Abstract
A tamper-evident cap is disclosed including a closure member and an annular wall depending outward therefrom to a bottom rim. Annular wall has a flange or sealing member extending inwardly adjacent to the closure member and a plurality of threads spaced apart and helically positioned to cooperate with respective threads of a container neck finish having substantially the same outward shape. A band is circumferentially positioned around the bottom rim including a pull tab and teeth. The pull tab extends from a part of the band and is preferably positioned within the circumference of the band. The teeth are mounted on a boss each tooth having an inner face angled acutely relative to the rim and being designed fit with the neck finish. A cap in combination with a neck finish having a vertical wall for sealing engagement with the cap annular flange is also disclosed.
Description
- The present invention relates to container caps and, more particularly, to tamper-evident caps for containers.
- Various types of caps exist for removably sealing containers, such as blow-molded or injection molded containers. One such cap has spiral threads extending along an interior surface which match spiral threads on the exterior of a compatible container neck. The threads enable a “screw-on” placement.
- Caps may further provide a tamper-evident means, such as a tear band, that is intended to show evidence if the cap has been tampered with or previously removed. Many tear bands fit about the cap diameter and cooperate with ratchet teeth on the corresponding container neck finish. Typically, the tear band has a pull tab that must first be torn and then removed to permit the end user to twist the cap off from the neck. However, current cap threads and neck finish engagements are not always effective to prevent the removal of the cap without first tearing the tear band. In such case, a so called tamper-evident cap can be removed from and reapplied to a container without leaving any visual evidence that it has been tampered with.
- Other tamper-evident bands, such as “drop bands,” are designed to remain on the container. When the cap is twisted the drop band drops down on the neck revealing that it has been separated from the cap. However, the band does not always drop down as it should and instead may falsely appear to be connected with the bottom of the cap when it is not.
- In addition to failing to provide visual evidence of a tampering, such configurations are not always effective for self-centering the cap on the container thereby resulting in a potential to cross thread during the capping operations. Thus there is a need to provide a tamper evident cap for containers that attaches and releases with relative ease while preventing the cap to be removed without also tearing the tear band and still providing visual evidence of tearing at point of purchase.
- In general, one aspect of the present invention is directed to a container cap including a closure member having an annular wall tapered or conically depending from the periphery of the closure member. At the other end of the depending annular wall is positioned a tamper-evident tear-off band. This band is secured to the annular wall by means of a raised boss at the bottom of the annular wall. The band includes a pull tab and ratchet teeth adapted to cooperatively engage teeth on the neck finish of the container to which it is fit to prevent removal of the cap without first removing the band. According to aspects, the pull tab is positioned within the circumference of the band, and, optionally, has a break-tie securing it to a part of the band. At least one of the teeth has an inner face at an acute angle relative to the bottom rim.
- Another aspect of the invention is directed to a neck finish formed having a conical wall that defines an opening therethrough. The wall includes a first end that is typically open to the outside and adapted to receive a cap, and a second end that terminates at the container body. At the first end there is a vertical wall with a lip extending inwardly of the wall and preferably outwardly of the plane of the opening to provide a secondary seal when cooperating with a cap of the present invention.
- In another aspect, embodiments of the invention include a bottle cap adapted to cooperatively engage the neck finish. In another aspect, the invention provides a tamper-evident cap having an outwardly conical annular wall in combination with a neck finish having substantially the same angular taper.
- Other objects, features, aspects and advantages of the present invention will become better understood or apparent from the following detailed description, drawings, and appended claims of the invention.

FIG. 8 shows a top plan view of a neck finish according to embodiments of the present invention. - As shown in
FIG. 1 , an embodiment of the present invention includes abottle cap 30 that can be used for sealing a container (not shown).Cap 30 has aclosure member 31 at one end and anannular wall 32 depending from the perimeter thereof and terminating with abottom rim 35 at its other end. Closuremember 31 is substantially circular and is designed to cover the mouth or opening in aneck finish 50 of a container 10, as shown for example inFIGS. 2 and 3 , and includes dependingvalve 48. Anannular flange 41 extends circumferentially from theclosure member 31 alongwall 32 at an acute angle relative to the plane ofmember 31. - A visual tamper-
evident band 34 extends around thebottom rim 35 of annular dependingwall 32. In an embodiment,annular wall 32 tapers outwardly fromclosure member 31 toband 34 and/or has a generally conical shape. The degree of tapering or conical structure depends, in part, on the dimensions of the container, particularly the neck finish, with which thecap 30 is used. In an example,annular wall 32 tapers at an angle of about 5° to about 20°; and, in specific example,annular wall 32 tapers outwardly to rim 35 at about 8°. In tests involving an approximately 38 millimeter cap, annular walls having an angle greater than above 11° were less effective in providing the advantages of this invention. The angle can be further adjusted for a 28 or 48 millimeter cap, or other sized cap, as such size is commonly referred to in the industry. The taper or conical structure of the cap and neck finish permits the cap to self-center on the neck during the capping process. The cap can be made from plastic such as high or low density polyethylene or any other resilient material that is suitable for securing a cap to a container. - The visual tamper-
evident band 34 includes apull tab 36, extending from a part of theband 34, andratchet teeth 39 aligned along an interior surface thereof. Theband 34 attaches to thebottom rim 35 of theannular wall 32 with at least oneboss 37 with a connection sufficient to affix the band thereto while also permitting the band to be torn from the wall to allow removal of the cap from the neck finish. In an example, multiple raisedbosses 37 run horizontally radially across thebottom rim 35 ofcap 30 and affix to thecorresponding ratchet teeth 39. As shown for example inFIG. 4 , the tips or corners ofratchet teeth 39 connect to an outward end ofbosses 37. In an embodiment, attachment of the ratchet teeth to thebosses 37 cooperates in preventing the cap from being removed from the container 10 without first removing thetear band 34. -
Pull tab 36 is positioned within the circumference of theband 34 and attached continuous therewith at break-tie 38. Optionally, in an example, a second break-tie joins a top portion ofband 34 to thebottom rim 35 of the cap opposite break-tie 38. In an example, thepull tab 36 is upwardly or downwardly extending. The extension ofpull tab 36 in combination with the tapering or conical structure ofannular wall 32 enablestab 36 to remain generally within the same circumference of theband 34 as shown, for example, inFIGS. 4 and 5 . This placement onband 34 leaves an open space between thewall 32 and thetab 36 in which the user can grab hold of the extending portion of thetab 36 and pull thetab 36 disengaging the break-tie 38 from theband 34. The conical shape allows thetab 36 ofband 34 to be tucked inward towardannular wall 32. Additionally, unlike many prior tamper-evident caps which have pull tabs that protrude beyond the band's outer circumference, the present cap is not hindered by such protrusion enabling it to move freely in an orientation roll sorter for positioning and appropriately orienting them for application to a container. Further, such circumferential positioning prevents the cap tabs from interlocking or entangling with tabs of other caps in the chute or sorter. Working in the 360 degree band circumference gives the cap an opportunity to roll without interference between the cap and orientation process. - In an example, a user removes
cap 30 by sliding a finger down alongannular wall 32 pushingtab 36 outward, and pullingtab 36 away fromwall 32 and severing break-tie 38 from a portion ofband 34. Absence of break-tie 38 provides the user with visual evidence that the cap has been tampered with or removed. - Ratchet
teeth 39 are adapted to engageteeth 58 on theneck finish 50 of a container 10, as shown, for example, inFIG. 2 . Theratchet teeth 39 are attached to the bottom of the cap body at raisedbosses 37 which secureband 34 to the cap. Eachratchet tooth 39 has aninner face 40.Inner face 40 is positioned at an acute angle α from the plane of cap 10. In an example, angle α is about 10° to about 20°, and, in another example, angle α is more preferably about 15° from the plane of the cap going inwardly. However, angle α could vary beyond these ranges if a cap having a longer profile is needed, for example, if a longer annular wall is used. That angle determination can be made within the scope of this invention by persons of ordinary skill in the art without undue experimentation. Angle α is important in the self-centering of the cap on the neck finish. Theinner face 40 is designed, in part, to permitcap 30 to expand over an outer edge of the neck finish when being applied to container 10. This helps to self center the cap on the container from a slight angle inputted by a capping machine to thus provide proper thread engagement. -
Cap 30 includes anannular flange 41 positioned on theannular wall 32 proximate toclosure member 31.Annular flange 41 extends at an angle β relative to theclosure member 31. In an example angle β is in the range of about 30° to about 60°. In another example, angle β is about 45°. According to aspects of the invention,inner face 40 andannular ring flange 41 are located and dimensioned to engage and cooperativelysecure cap 30 onto the neck finish of a container. For example as illustrated inFIG. 3 , capinner face 40 andflange 41 cooperate with anannular flange 59 and anannular lip 57 of theneck finish 50 of a container 10, respectively, when the cap is screwed onto the neck finish. In an example, theinner face 40 sits between the bottom end of theneck finish 56 and aprotective rim 70 on the container 10. - Several sets of helically spaced
threads 43 are positioned on the inner surface ofannular wall 32 generally extending from theclosure member 31 proximate to theannular flange 41 to thebottom rim 35. Eachthread 43 has a respective lead opening 44 andtail 45. Thethreads 43 are tapered toward lead openings 44 andtails 45. The conical or taper design ofannular wall 32 andthreads 43 helps allow thecap 30 to self center on the neck of a container. Further, the tapered or conical design minimizes the chance that threads would over strip or cross thread. In an example, there are at least five thread leads 44 each one beginning at about 72 degrees around the inner surface ofannular wall 32. Preferably,threads 43 extend more than 90 degrees and less than 360 degrees around the inner surface ofannular depending wall 32. In an example,threads 43 extend around the inner surface about 180 degrees. According to an aspect of the invention,threads 43 project inwardly fromannular wall 32 at an angle γ. Angle γ is in the range of about 30 degrees to about 90 degrees, and, preferably, angle γ is about 60 degrees, plus or minus five degrees. - Depending from
closure member 31, isannular valve 48.Annular valve 48 is positioned at a distance fromannular wall 32 that will permit insertion of the top portion of a container neck finish to fit therebetween. In an example, thevalve 48 is spaced from an internal surface of the annular depending wall at a distance that is sufficient to engage an annular lip on the neck finish. In an example, this joinder creates acorner area 47 for accepting the “updraft” from the top rim of the neck of a container. Typically, thecorner area 47 provides a right angle into which the top rim fits sufficiently to create a sealing engagement. In an example, this rim and the top portion of the container neck fit comfortably between theannular flange 41 andannular valve 48. Thevalve 48 extends to a point near to the start ofthreads 43. In an example,valve 48 includes ataper 49 which facilitates initial engagement of the valve to the inner periphery of the neck finish of a container opening. - In another example of
cap 30,annular valve 48 may be eliminated. In this example it will be preferable to also eliminateannular ring valve 41. With removal ofannular valve 48, and preferablyring flange 41, a circular sealing member, not shown, would be positioned substantially withclosure member 31 to provide a seal between said closure member andopening 53. The sealing member is preferably a disk made of foils, foam, paper or the like. This example entails an additional step of the sealing member placement prior to the bottle capping operation. - In an example,
cap 30 has outer ribs orserrations 46 extending along the exterior ofannular wall 32. Generally serrations 46 extend from the perimeter ofclosure member 31 to thebottom rim 35. According to embodiments,serrations 46 taper toward thebottom rim 35 and have an outer spine that is substantially perpendicular to the plane of theclosure member 31. In an example, sets ofserrations 46 are positioned equidistant about the circumference ofannular wall 32. In an example, each set contains two to four serrations. In an example there are eight sets of serrations, the majority of which sets contain about two, and preferably three,serrations 46.Serrations 46 in combination withthreads 43 prevent the cap from nesting when stacked with other caps. - According to aspects of an embodiment, the present invention includes a
conical neck finish 50 of a container 10, as illustrated for example inFIG. 2 .Neck finish 50 preferably has substantially the same tapered or conical angle of revolution ascap 30.Neck finish 50 includes anannular wall 52 defining therethrough acylindrical opening 53 having afirst end 54 and asecond end 56.First end 54 provides access toopening 53. Near opening 53, avertical wall 55 and anannular lip 57 are provided at the first end of theannular wall 52.Vertical wall 55 is positioned substantially perpendicular to the plane of afitting closure member 31. Slight variance in the perpendicular is acceptable; however, a significant divergence may prohibit engagement of the cap to the neck finish. In an example, the vertical wall varies at less than about an 8 or 10 degree angle, and, preferably it is perpendicular.Annular lip 57 extends inward from thevertical wall 55 and terminates at theinner diameter 51 of the container. Theinner diameter 51 is also situated at the end of the updraft. Preferably theannular lip 57 extends inwardly at a slight outward angle from the plane of the first end as shown inFIGS. 2 and 3 . - In an example, when
cap 30 is applied to theneck finish 50,annular valve 48 is spaced apart from annular wall 32 a distance which is represented by the difference in the radial distance from the outer edge ofannular wall 32 at its closure end and the center of a container neck opening and the inner edge of thelip 57. The outer diameter ofvalve 48 together withannular flange 41 on the cap enhance sealability ofcap closure member 31 by creating pressure on the container neck. In an embodiment, as thevalve 48 penetrates theinner diameter 51 pushes inward to opening 53, updraft of 57 deflects inward andvertical wall 55 is pushed outward on the neck.Annular flange 41 actuates on the top portion ofvertical wall 55 pushing it back thereby creating a secondary seal. - Positioned adjacent to the
second end 56 is at least one set ofannular ratchet teeth 58 to provide a tamper evident grip for the cap. Ratchetteeth 58 may be positioned around the entire circumference of thesecond end 56 of the neck or only a portion thereof. In an embodiment, there are two sets ofteeth 58 positioned aboutend 56 with aflat wall 69 separating them at each end of both. Each set consists of eight to twelveteeth 58, although they need not have an equal number. In an example, each set has ten teeth. In an embodiment, theteeth 58 of two different sets ofteeth 58 are positioned in opposing directions to prevent “backing off” the cap from the bottle neck. Ratchetteeth 58 are adapted to cooperatively engagecorresponding teeth 39 on the tamper-evident band 34 positioned on themating cap 30. - In an embodiment of the invention, an
annular ring flange 59 is positioned substantially adjacent to the plane in which theannular ratchet teeth 58 are provided. Thisflange 59 in cooperation withannular lip 57 provides a means for securing the cap to the bottle. In an example, the cap snaps over and locks onto the neck finish. - Helically extending between the
annular lip 57 and theannular ring flange 59, are at least threethreads 64 leading atpoints 66 and terminating atpoints 67, adjacentfirst end 54 andannular ring flange 59, respectively.Threads 64 are helically spaced in contiguous relationship as shown inFIG. 2 . In an example, there are fivethreads 64. In embodiments, eachthread 64 extends around the circumference ofannular wall 52 at a degree corresponding to that ofcap threads 43. - In an example, when
cap 30 is applied to theneck finish 50 of a container, the threads of the cap contact the top of the threads of the container neck finish before thevalve 48 orflange 41 contact the inside dimension of the container. In an example,cap threads 43 engage thebottle threads 64 before theratchet teeth 58 engage. The cap threads engage with the rotating of the cap engaging the threads of neck finish and engaging thecap 30.Valve 48 cooperates withflange 41 to seal contents whenlip 57 pushes against the valve during engagement of the threads. - The
protective rim 70 extends downwardly and outwardly from theratchet teeth 58. Theprotective rim 70 protects the tamper-evident band 34 from intrusion, for example, by an object that could be used to dislodge the tamper-evident band 34 without tearing it and enable the cap to release from the container. The neck finish can be made of plastic such as high or low density polyethylene of any other material suitable for use with the contents of the container. The material may be the same as that of the container. -
Cap 30 when used in combination withneck finish 50 of the present invention provides a seal that is particularly well suited to standard beverage containers, such as blow molded milk containers. When properly sealed, air will not penetrate through the container opening. Use of the tamper-evident band 34 withbreak tie 38 makes it extremely difficult, if not impossible, to tamper with the contents of the bottle without indicating evidence thereof on the cap. Use of optional second break-tie provides a further security seal. - The embodiments of the invention shown and described in the above figures are exemplary of numerous embodiments that may be made within the scope of the invention. It is to be understood that the detailed embodiments, figures and examples are presented for elucidation and not limitation. The invention may be otherwise varied, modified or embodied within the scope of the invention as defined in the appended claims.
