Definitions
- Example embodiments in general relate to child-resistant closure systems for containers.
- CPSC Consumer Product Safety Commission
- Imidazolines are a family of drugs that are vasoconstrictors indicated for nasal congestion and/or ophthalmic irritation. Products containing imidazolines can cause serious adverse reactions, such as central nervous system (“CNS”) depression, decreased heart rate, and depressed ventilation in children treated with these drugs or who accidentally ingest them.
- CNS central nervous system
- the CPSC has preliminarily found that availability of 0.08 milligrams or more of an imidazoline in a single package, by reason of its packaging, is such that special packaging is required to protect children under 5 years old from serious personal injury or illness due to handling, using, or ingesting such a substance.
- the CPSC has taken this action under the Poison Prevention Packaging Act of 1970.
- CRC child-resistant closure
- An example embodiment is directed to a child-resistant closure system for a pump sprayer.
- the system includes a cap having a rim at its lower end and including a pair of legs, each leg in opposite relation to one another and extending downward from the rim, each leg tapered and including a rib thereon which extends outward from the side of the leg, with an undercut provided between each rib and the rim of the cap.
- the system includes a dispensing tip configured to receive the cap thereon, a lower end of the dispensing tip including a pair of finger-depressing shoulders in opposite relation to one another and extending horizontally outward from the dispensing tip, each shoulder including a slot therein that is configured to receive a corresponding leg of the cap therethrough for locking the cap to the dispensing tip, with a cylindrical collar provided beneath the shoulders as the bottom end of the dispensing tip, the collar including a pair of buttons in opposite relation to one another on a vertical facing of the collar, the buttons configured to be simultaneously actuated to release the legs from interior structure within the dispensing tip so as to remove the cap off of the dispensing tip.
- the system includes a cylindrical base having its upper end secured to the collar of the dispensing tip and its lower end secured to a dispenser bottle which contains fluid, the dispensing tip and base housing a sprayer pump unit therein which partly extends into the dispenser bottle interior and which is actuated by depressing the shoulders on the dispensing tip to spray the fluid within the dispenser bottle.
- the legs With the cap in place on the dispensing tip, the legs extend downward through the slots in the shoulders to contact the top of the base, with interior structure within the dispensing tip engaged in the undercuts provided between the ribs of the legs and the rim of the cap so as to allow for the sprayer pump unit to be locked out from operation.
- buttons on the collar are pressed simultaneously to deflect the legs inward and off of the base, which also deflects the corresponding ribs on the legs away from interior structure within the dispensing tip, so that the cap with its legs is drawn up through the slots in the shoulders and off of the dispensing tip.

Description
- The present application claims the benefit under 35 U.S.C. §119(e) of U.S. Provisional Patent Application No. 61/802,060 to the inventors, filed Mar. 15, 2013, the entire contents of which is hereby incorporated by reference herein.
- 1. Field
- Example embodiments in general relate to child-resistant closure systems for containers.
- 2. Related Art
- The Consumer Product Safety Commission (“CPSC”) proposed a rule in early 2012 to require child-resistant (“CR”) packaging for any over-the-counter or prescription product containing the equivalent of 0.08 milligrams or more of an imidazoline, a class of drugs that includes tetrahydrozoline, naphazoline, oxymetazoline, and xylometazoline, in a single package. Imidazolines are a family of drugs that are vasoconstrictors indicated for nasal congestion and/or ophthalmic irritation. Products containing imidazolines can cause serious adverse reactions, such as central nervous system (“CNS”) depression, decreased heart rate, and depressed ventilation in children treated with these drugs or who accidentally ingest them. Based on the scientific data, the CPSC has preliminarily found that availability of 0.08 milligrams or more of an imidazoline in a single package, by reason of its packaging, is such that special packaging is required to protect children under 5 years old from serious personal injury or illness due to handling, using, or ingesting such a substance. The CPSC has taken this action under the Poison Prevention Packaging Act of 1970.
- Accordingly, as it is expected that this rule will become law, manufacturers will be required to develop child-resistant closure (CRC) systems for their nasal pump sprayers and eye-dropper dispenser products (such as Visine®), as each of these products contain the equivalent of 0.08 milligrams or more of an imidazoline. In doing so, one goal is to ensure that the newly developed dispensers are robust enough to prevent children five years old and under from being able to inadvertently open the bottle to use or ingest the contents, while still being “senior friendly” to mature adults.
- Moreover, the same child-resistant principals as to be applied to nasal sprayers and eye-dropper (squeeze) bottles so as to comply with impending CR packaging regulations, could also be made applicable to other fields of fluid dispenser/packaging. For example, little or no thought has be given to developing CRC systems for consumer fluid pump dispensers having a viscosity generally higher than that of water or water-based medicinal fluids, such as those dispensers holding lotions, shampoos, baby oils, and paints.
- An example embodiment is directed to a child-resistant closure system for a pump sprayer. The system includes a cap having a rim at its lower end and including a pair of legs, each leg in opposite relation to one another and extending downward from the rim, each leg tapered and including a rib thereon which extends outward from the side of the leg, with an undercut provided between each rib and the rim of the cap. The system includes a dispensing tip configured to receive the cap thereon, a lower end of the dispensing tip including a pair of finger-depressing shoulders in opposite relation to one another and extending horizontally outward from the dispensing tip, each shoulder including a slot therein that is configured to receive a corresponding leg of the cap therethrough for locking the cap to the dispensing tip, with a cylindrical collar provided beneath the shoulders as the bottom end of the dispensing tip, the collar including a pair of buttons in opposite relation to one another on a vertical facing of the collar, the buttons configured to be simultaneously actuated to release the legs from interior structure within the dispensing tip so as to remove the cap off of the dispensing tip. The system includes a cylindrical base having its upper end secured to the collar of the dispensing tip and its lower end secured to a dispenser bottle which contains fluid, the dispensing tip and base housing a sprayer pump unit therein which partly extends into the dispenser bottle interior and which is actuated by depressing the shoulders on the dispensing tip to spray the fluid within the dispenser bottle. With the cap in place on the dispensing tip, the legs extend downward through the slots in the shoulders to contact the top of the base, with interior structure within the dispensing tip engaged in the undercuts provided between the ribs of the legs and the rim of the cap so as to allow for the sprayer pump unit to be locked out from operation. To release the cap so as to permit actuation of the sprayer pump unit via the shoulders, the buttons on the collar are pressed simultaneously to deflect the legs inward and off of the base, which also deflects the corresponding ribs on the legs away from interior structure within the dispensing tip, so that the cap with its legs is drawn up through the slots in the shoulders and off of the dispensing tip.

FIG. 1 is a perspective view of a child-resistant closure system for a pump sprayer according to an example embodiment. The child-resistant closure (CRC)system 100 includes acap 110, a dispensingtip 120 and abase 130. Each of thecap 110, dispensingtip 120 andbase 130 may be injection molded or extruded or otherwise formed of a suitable plastic material, as is known. Thecap 110 is 3-sided to minimize rolling and avoid losing thecap 110. Thebase 130 has interior grooves or threads for coupling it to a threaded member ondispenser bottle 140 which holds the medicinal fluid therein. Thebase 130 and dispensingtip 120 also enclose a sprayer pump unit 150 (not shown) which partly extends into thedispenser bottle 140 interior. - In an example, the
CRC system 100 described here and child-resistant based embodiments to be described hereafter may be applicable, but not limited to: single or multi-dose dispensers such as nasal sprayers, ocular sprayers, dermal sprayers, misters, aerators, airless dispensers, air-use dispensers, spouted and non-spouted pump assemblies, and the like. The containers or dispensers foreseeable have applications in the healthcare, home and garden, beauty and food and beverage industries, thus the embodiments described herein are applicable to dispensers or containers configured for, but not limited to dispensing nasal medicine, sunscreens, food products, paints and protectants, deodorants, insect repellants, sealed breath fresheners, ear medicine, dermal medicine, lotions, fragrances, air fresheners, spray starches, oxygen, insecticides, fungicides, herbicides, rodenticides, spray oils, talcs, and spray food stuffs. Further, the CRC systems can be varied in size and applied as a platform to handle any desired viscosity of fluid. -
FIG. 2 is an enlarged view of a portion of an interface between cap and dispensing tip to show selected components thereof. The dispensingtip 120 includes fingerdepressing shoulders 121 on which is formed a plurality ofslots Slots 123 are adapted to receive correspondinghooks 111 which extend from thebottom rim 113 ofcap 110.Slots 124 are adapted to receive extendinglegs 112 of thecap 110. As will be seen, thehooks 111 andlegs 112 prevent actuation ofshoulders 121 in a locked condition, with thehooks 111 preventing removal of thecap 110 whether or not thecap 110 is locked or unlocked to thedispensing tip 120. -
FIG. 3A is a portion of a sectional view of the system in the yz-plane to illustrate a locked condition,FIG. 4 is a portion of a sectional view of the underside of the dispensing tip in the xz-plane with selected components removed to illustrate a locked condition, andFIG. 5 is a portion of a sectional view of the system in the xy-plane to illustrate an locked condition. Referring toFIGS. 3A-5 , when thecap 110 is inserted into theslots hooks 111 snap fit intoslots 123 and lock, such that ahook 111 and therim 113 ofcap 110 captures part of dispensingtip 120 around the edge ofslot 123, as can be seen in bothFIGS. 3 and 4 . As shown inFIG. 5 , thelegs 112 extend all the way down throughslots 124 to terminate againstbase 130. Accordingly, depression ofshoulders 121 to activatesprayer pump unit 150 is not possible; operation is locked out. -
FIG. 3B is a portion of a sectional view of the system in the yz-plane to illustrate an unlocked condition, andFIG. 6 is a portion of a sectional view of the underside of the dispensing tip in the xz-plane with selected components removed to illustrate an unlocked condition. To remove thecap 110, a user needs to rotate thecap 110, as best seen inFIG. 6 . This aligns thehooks 111 andlegs 112 in the wider portions of theirslots cap 110 is loose, thehooks 111 are still retained to the inner lip surface of dispensingtip 120. In order to fully remove thecap 110 and permit pump actuation, one must squeeze bothribbed members 114 on the outer surface ofcap 110, simultaneously. Theribbed members 114 are seen best inFIG. 2 . By squeezing both ribbedmembers 114 simultaneously, thehooks 111 will deflect inward into the open larger slot space ofslot 123, permittingcap 110 removal. - Thus, when
cap 110 is in either the “locked” or “unlocked” position, thehooks 111 prevent thecap 110 from being removed, as they are always engaged under the surface of the dispensingtip 120. By placing the cap in the “unlocked” position and squeezing the sides of thecap 110 at theribbed members 114, thehooks 111 are allowed to disengage and thecap 110 can be removed. Unlike locking caps which are “squeeze and twist”, this design is “twist and squeeze. Additionally, because thehooks 111 snap into place when thecap 110 is installed, the end-user has the option of leaving thecap 110 unlocked, but it will still need to be squeezed to remove it, and it won't fall off. Moreover, as theshoulders 121 cannot be depressed with thecap 110 on, even loosely, it will still prevent accidental deployment. -
FIG. 7 is a front view of a child-resistant closure system for a pump sprayer according to another example embodiment. The child-resistant closure (CRC)system 200 includes acap 210, a dispensingtip 220 and abase 230. Each of thecap 210, dispensingtip 220 andbase 230 may be injection molded or extruded or otherwise formed of a suitable plastic material, as is known. Thecap 210 is 3-sided to minimize rolling and avoid losing thecap 210. Thebase 230 has interior grooves or threads for coupling it to a threaded member ondispenser bottle 240 which holds the medicinal fluid therein. Thebase 230 and dispensingtip 220 also enclose a sprayer pump unit 250 (not shown) which partly extends into thedispenser bottle 240 interior. -
FIG. 8 is a perspective view of a cap according to the system ofFIG. 7 .Cap 210 has a pair oflegs 211 extending downward on either side. Eachleg 211 has arib 215 separated from therim 213 of thecap 210 by an undercut 216. -
FIG. 9 is a front perspective view of a dispensing tip according to the system ofFIG. 7 , andFIG. 10 is a top view of the dispensing tip shown inFIG. 9 .Dispensing tip 220 includes a pair ofshoulders 221 that are used to depress thesprayer pump unit 250 within (not shown) under finger pressure, as is known. On either side is provided a pair ofbuttons 222 withreliefs 224 separated by ahinge 225 that acts as a cam when thebutton 222 is actuated by the user. Aramp 227 is position on the back side of eachrelief 224; this interfaces with eachleg 211, once thelegs 211 are inserted throughslots 223 in theshoulders 221 of dispensingtip 220. -
FIG. 11 is a bottom perspective view of a base according to the system ofFIG. 7 ,FIG. 12 is a dispenser bottle usable with the system ofFIG. 7 , andFIG. 13 is a top view of the bottle shown inFIG. 12 . Referring toFIGS. 11-13 , an anti-back off feature has been added to both thedispenser bottle 240 andbase 230. Thebase 230 is formed withinternal threads 231 andserrated teeth 232 at its bottom skirt. Upon full seating of the base 230 to thebottle 240, the downward force of application will push the bottom skirt of the base 230 over formedteeth 242 in thebottle 240, providing a secure method of application where tampering to remove the base 230 would be evident and would eliminate accidental removal. -
FIG. 14 is a portion of a sectional view taken of the system to shown a locked condition;FIG. 15 is a partial bottom perspective view of the dispensing tip, andFIG. 16 is a portion of a cross-cut of the cap and dispensing tip in the xz-plane to show positions of the legs and buttons in a locked position. Referring toFIG. 16 , once thecap 210 is placed on thedispensing tip 220, thelegs 211 travel through theslots 223 and ride over theramps 227 to lock into place, as best shown inFIG. 16 . In this locked condition,collar 226 of the dispensingtip 220 is retained between therim 213 ofcap 210 and therib 215, as best seen inFIG. 14 . Theleg 211 extends all the way down to thebase 230, locking out movement of theshoulders 221 and hencesprayer pump unit 250. - To unlock for operation, the user depresses both
buttons 222 inward. This causes theramps 227 to cant outward by way of the cam action ofhinges 225. This allowslegs 211 free travel. The user then rotates thecap 210 30 degrees after having depressed bothbuttons 222 to release thecap 210 from the dispensingtip 220. With the cap removed, actuation is now possible viashoulders 221. - Although the embodiment shown in
FIGS. 7-16 describes acap 210 having two legs that is twist to lock, in which the cap locks out actuation of a nasal pump sprayer, the exact same embodiment can be accomplished with acap 210 having a single button actuating asingle leg 211. The functions of locking and unlocking operations described above with a single button, having essentially the same construction and functionality asbutton 222 on dispensingtip 220, and a single leg having the same construction asleg 211, would accomplish the same goal of locking outshoulder 221 of the dispensingtip 220, as theleg 211 would extend all the way tobase 230. The other side would by legless but have a dummy button for manufacturing purposes. -
FIG. 17 is a front view of a child-resistant closure system for a pump sprayer according to another example embodiment, andFIG. 18 is a side view of the system ofFIG. 17 . Referring toFIGS. 17 and 18 , the child-resistant closure (CRC)system 300 includes acap 310, a dispensingtip 320 and abase 330. Each of thecap 310, dispensingtip 320 andbase 330 may be injection molded or extruded or otherwise formed of a suitable plastic material, as is known.

Additionally,FIG. 79A is a sectional view taken in the xy plane of a portion of the system to show a locked condition thereof. Referring toFIGS. 77 to 79 , there is shown the engagement of thebottle cap 1350 to thetank 1340 and the engagement of thebottle cap 1350 andtank 1340 to thebase 1330. Specifically, the base includesinterior grooves 1331 which mate withexterior threads 1351 oncap 1350. Optionally, thebase 1330 can have the configuration shown inFIG. 11 . Specifically, thebase 1330 can be configured with serrations (teeth) on its skirt (shown by arrow 1332), so as to form a mechanical bond with corresponding teeth or serrations (shown by arrow 1352) formed on the bottle cap skirt, upon screwing thebase 1330 down onto thethreads 1351 of thebottle cap 1350 to seat thesystem 1300 on the dispenser bottle. - In operation, with the
cap 1310 in place and thelegs 1311 secured in theslots 1323, actuation of thepump head 1315 is locked out. Specifically, thecap 1310 is retained by the twolegs 1311 which are tapered, with horizontal undercuts that engage withtabs 1327 that extend from a backside of arelief portions 1324 on thebuttons 1322 on thedispenser 1320, as shown inFIG. 79 . When engaging, thecap 1310 is placed and turned in a clockwise motion, which will press thelegs 1311 against thetabs 1327 extending from the underside of therelief portions 1324 of thebuttons 1322, as shown inFIG. 79 . This in turn forces thetabs 1327 to deflect outwards until the undercuts on thecap 1310 pass. Once clear, thetabs 1327 snap into position behind the undercuts on thelegs 1311 and lock thecap 1310 in place. As best shown inFIG. 78 , thelegs 1311 extend to the top of thebase 1330 and allow for thedispenser 1320 to be locked out while thecap 1310 is in place. - To release the
cap 1310, thebuttons 1322 on thecap 1310 must be simultaneously pressed in a horizontal inward motion. This causes theramps 1327 onreliefs 1324 to cant outward by way of the cam action ofhinges 1325, which in turn causes thelegs 1311 to deflect outwards. The user then rotates thecap 1310 30 degrees (into the wider part of slot 1323) after having depressed bothbuttons 1322 to release thecap 1310 from thedispenser 1320. This also placesspout 1316 in the unlocked position inaperture 1314, as shown inFIG. 74 . Thecap 1310 can then be removed, so that actuation ofpump head 1315 is now possible. -

Specifically, thebase 1430 can be configured with serrations (teeth) on its skirt (shown by arrow 1432), so as to form a mechanical bond with corresponding teeth or serrations (shown by arrow 1452) formed on the bottle cap skirt (similar to as shown on the bottle skirt ofFIGS. 12 and 13 ), upon screwing thebase 1430 down onto thethreads 1451 of thebottle cap 1450 to seat thesystem 1400 on the dispenser bottle. -
FIG. 86 is a sectional view taken in the xy plane of a portion of the system to show a locked condition thereof.FIG. 86 is provided to help describe the locked and unlocked conditions forcap 1410. With thecap 1410 in place and thelegs 1411 secured in theslots 1423, actuation of thepump head 1415 is locked out. Specifically, thecap 1410 is retained by the twolegs 1411 that are tapered, withundercuts 1419 that engage with the underside of theslots 1423 on thedispenser 1420. When engaging, thelegs 1411 will deflect inwards until theundercuts 1419 pass the slots on thedispenser 1420, where thelegs 1411 will snap back to vertical and engage, with a portion of thedispenser 1420 captured in theundercuts 1419 between theribs 1418 and rim 1413 off thelegs 1411. Thelegs 1411 extend to the top of thebase 1430 and allow for thedispenser 1420 to be locked out while thecap 1410 is in place. Accordingly, operation of thepump head 1415 is locked out. - To release the
cap 1410 into an unlocked condition, thebuttons 1412 on thecap 1410 must be pressed simultaneously, causing thelegs 1411 to once again deflect inwards and thecap 1410 can be drawn up and off of thedispenser 1420. With thecap 1410 removed off ofspout 1416, thepump head 1415 is now free to dispense. -
FIG. 87 is a front view of a child-resistant closure system for a pump sprayer according to another example embodiment,FIG. 88 is a perspective view of a cap according to the system ofFIG. 87 , andFIG. 89 is a bottom perspective view of a dispensing tip according to the system ofFIG. 87 .System 1500 is identical tosystem 200 previously described above, with the exception that only one button is present on dispensingtip 1520 and only oneleg 1511 is included oncap 1510. Otherwise, all other functionality of thesystem 1500 follows that ofFIGS. 7-16 which describesystem 200. Accordingly, a refresher on the operation and mechanical bonds formed when thecap 1510 is in place on thedispensing tip 1520 is hereafter described. -
FIG. 90 is a portion of a sectional view taken of the system in the xy-plane to show a locked condition. In addition to the mechanical bond formed between the serrated teeth (not shown) on the lower skirt ofbase 1530, which engages with teeth on dispenser bottle skirt 1540 (referring back to the anti-back off feature first described inFIGS. 11-13 , which is applicable both thesystem 200 and here),FIG. 90 shows where a portion of thedispensing tip 1520 on the underside ofslots 1523 is captured between therim 1513 ofleg 1511 and therib 1515. Theleg 1511 also extends all the way down tobase 1530, locking out actuation. - In operation, once the
cap 1510 is placed on thedispensing tip 1520, theleg 1511 travels through theslot 1523 and rides over theramp 1527 to lock into place. In this locked condition, a portion of the dispensingtip 220 is retained between therim 1513 ofcap 1510 and therib 1515, as best seen inFIG. 90 . Theleg 1511 extends all the way down to thebase 1530, locking out movement of theshoulders 1521 and hencesprayer pump unit 1550. - To unlock for operation, the user depresses the
button 1522 inward. This causes theramp 1527 to cant outward by way of the cam action ofhinge 1525. This allowsleg 1511 free travel. The user then rotates thecap 1510 and draws it up off of thedispensing tip 1520. With thecap 1510 removed, actuation is now possible viashoulders 1521. -
FIG. 91 is a perspective view of a child-resistant closure system for a pump sprayer according to another example embodiment, andFIG. 92 is an exploded view of the system ofFIG. 91 .System 1600 is identical tosystem 600 previously described above, with the exception that theretainer collar 630 has been replaced with a modifiedcrimp seal 1645, and the top of the dispenser bottle at theferrule portion 641 has been modified to add alip 1643 for thecrimp seal 1645. Otherwise, all other functionality of thesystem 1600 follows that ofFIGS. 31-36 which describesystem 1600. Accordingly, a refresher on the operation and mechanical bonds formed when thecap 1610 is in placed on thedispensing tip 1620 is hereafter described. -
FIG. 93 is a portion of a sectional view taken of the system in the xy-plane to show a locked condition. Initially, the mechanical bond formed with thecrimp seal 1645 is described. Referring toFIG. 93 , and noting that any ferrule body embodiment utilizing a retainer collar may be replaced with the following, the inventors modified theferrule portion 1641 of thedispenser bottle 1640 to add alip 1643. A metallic orsynthetic crimp seal 1645 was then added, crimped at a substantial pressure, so as to seat at the underside of therim 1643, to form a mechanical bond with therim 1643 as it engages an inner wall surface ofdispenser tip 1620. - In operation, with the
cap 1610 inserted through theslots 1623, thelegs 1611 contacting base 1630, operation of theshoulders 1621 is locked out; actuation ofsprayer pump unit 1650 is not possible. Specifically, thecap 1610 is retained by the twolegs 1611, with undercuts 16116 that engage with the underside of theslots 1623 on theshoulders 1621 of thedispensing tip 1620, and the twotabs 1614 that extend from thelevers 1612 on thecap 1610. When engaging, thelegs 1611 will pass theslots 1623 and engage with thedispensing tip 1620 once turned clockwise. At the end of the turning motion, thetabs 1614 deflect downward and engage with theshoulder 1621 portion atslot 1623 to lock out thecap 1610 and keep it from disengagement. As noted, thelegs 1611 extend to the top of the base 1630 and allow for the sprayer pump unit 1650 (by way of shoulders 1621) to be locked out while thecap 1610 is locked in place. - To release the
cap 1610, thelevers 1612 must be pressed inward simultaneously, causing thetabs 1614 to deflect upwards. Thecap 1611 is then turned in a counter-clockwise motion, drawn up through wider portion ofslot 1623, and off of thedispensing tip 1620. Withcap 1610 removed, downward movement of theshoulders 1621 to actuate thesprayer pump unit 1650 is possible. -
FIG. 94 is a front view of a child-resistant closure system for a pump assembly according to another example embodiment,FIG. 95 is an exploded view of selected components of the system ofFIG. 94 , andFIG. 96 is a top view of the dispenser according to the system.System 1700 is identical tosystem 1300 previously described above, with the exception that the spouted pump unit has been replaced with a spray pump unit. Otherwise, all other functionality of thesystem 1700 follows that ofFIGS. 74-79 which describesystem 1300. Accordingly, a refresher on the operation and mechanical bonds formed when thecap 1710 is in placed on thedispenser 1720 is hereafter described. -
FIG. 97 is sectional view A-A taken fromFIG. 96 . Reference should be made toFIG. 79 as well for the following discussion, which shows specifics of thedispenser 1320/1720 in cross section with the legs (same construction). In operation, with thecap 1710 in place and thelegs 1711 secured in theslots 1723, actuation of thepump head 1715 is locked out. Specifically, thecap 1710 is retained by the twolegs 1711 which are tapered, with horizontal undercuts that engage with tabs 1327 (1727) that extend from a backside of a relief portions 1324 (1724) on thebuttons 1722 on the dispenser 1720 (see related references inFIG. 79 ). When engaging, thecap 1710 is placed and turned in a clockwise motion, which will press thelegs 1711 against the tabs 1327 (1727) extending from the underside of the relief portions 1324 (1724) of the buttons 1722 (seeFIG. 79 for related element numbers). This in turn forces the tabs 1327 (1727) to deflect outwards until the undercuts on thecap 1710 pass. Once clear, the tabs 1327 (1727) snap into position behind the undercuts on thelegs 1711 and lock thecap 1710 in place. As best shown inFIG. 97 , thelegs 1711 extend to the top of thebase 1730 and allow for thedispenser 1720 to be locked out while thecap 1710 is in place. - To release the
cap 1710, thebuttons 1722 on thecap 1710 must be simultaneously pressed in a horizontal inward motion. This causes the tabs 1327 (1727) to cant outward by way of the cam action of hinges 1325 (1725), which in turn causes thelegs 1711 to deflect outwards. The user then rotates thecap 1710 30 degrees (into the wider part of slot 1723) after having depressed bothbuttons 1722 to release thecap 1710 from thedispenser 1720. Thecap 1710 can then be removed, so that actuation ofpump head 1715 is now possible. - The example embodiments being thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as departure from the example embodiments, and all such modifications as would be obvious to one skilled in the art are intended to be included in the following claims.
