Description

Dec. 29, 1959 A. HALPERN CONTAINER CLOSURE AND POURING SPOUT Filed March 18, 1957 I l 22 I4 25 23 INVENTOR. Israel A. Halpem WWW Afforneys nited States This invention relates to a new closure for containers and pouring spout for containers, as glass bottles adapted to contain liquids such as liquor, vinegar, salad oil and the like. The present invention is a continuation-in-part of my copending application Serial No. 476,149 filed December 20, 1954, now Patent No. 2,790,582.
it is an object of the present invention to provide an improved closure and pouring spout for containers wherein the contents of a glass bottle or the like may be eifectively sealed therein and yet which operates as a pouring or dispensing spout when in operaive pouring position. It is a principal object of the present invention to provide a pouring spout which effectively prevents dripping or leakage of the fluid product dispensed upon termination thereof.
It is a well known fact that loss of liquid by dripping from the pouring end of a bottle causes considerable loss. in the case of whiskey, for example, the loss by dripping may be very substantial and work an economic loss of considerable magnitude in bars or other such locations. In the case of salad oils, drippings from the open or pouring end of the bottle quickly discolors labels attached to the bottle, and affords a very unsightly appearance to the container. The present invention provides a pouring spout which prevents after-pouring leakage or dripping.
Further objects of the present invention are to provide a closure and pouring spout which may be employed with conventional containers such as glass bottles, and used in the place and stead of conventional stoppers, caps, and the like. The dispensing spout is so arranged that when in closed or inoperative position a revenue stamp, as used with liquor bottles, may be installed in conventional fashion. It is a specific object to provide a pouring spout wherein the breathing orifice is built into the plug in such a way as to insure proper breathing during pouring.
Additional advantages of the present invention stem from employment of a closeable dispensing spout which operates as an eflicient closure for a bottle to prevent evaporation or spillage of contents and further prevents ingress of insects and the like to the contents, as hapens with pouring spouts presently in use.
Other objects and advantages of the invention will be apparent upon review of the specification and reference to the accompanying drawings in which similar characters of reference represent corresponding parts in each of the several views.
In the drawings:
Fig. l is a vertical sectional view through a portion of a container with the pouring spout in closed position;
Fig. 2 is a view similar to Fig. l with the pouring spout in open or pouring position;
Fig. 3 is a sectional view taken on the line 33 of Fig. 2; and
Fig. 4 is a front elevational view of the plug member.
The device of the instant invention is illustrated as installed in the neck 11 of a conventional bottle provided with an external groove 12 on the upper end thereof. A metal cap 13 engages groove 12 and is formed with a central aperture 14. Cap 13 holds the pouring spout in place. Seated within the bottle top is a sleeve 17 formed of impervious plastic material such as polyethylene resin, neoprene or the like. The sleeve is provided with an annular flange 18 which fits against the top of the neck of the bottle and is sandwiched between metal cap 13 and the top bearing surface 19 of the bottle. Disposed slidably within sleeve 17 and through cap aperture 14 is a plug member indicated generally at 22. The plug is preferably formed of liquid impervious plastic material such as polyethylene resin or neoprene or other suitable material. The plug is provided with an enlarged head 23 which is superposed over cap 13 when in closed position. An annular recess may be formed in the top surface of flange 18 to receive a cork gasket 25. A'revenue stamp is illustrated at 24 and may be applied in the usual fashion to prevent unauthorized opening of a sealed bottle.
Plug 22 fits slidably and snugly within sleeve 17 and is provided with an external bead 28 adjacent its lower end to limit withdrawal of the plug beyond a predetermined limit relative to sleeve 17. The plug is provided with a central bore 32 extending up from its bottom to enable liquid to discharge from the interior of the container through a pouring hole indicated generally at 33. The bottom of the plug is cut away at an oblique angle in respect to the longitudinal axis of bore 32, as indicated by reference numeral. 34 so that the liquid opening 35 is generally elliptical and presents an enlarged initial opening for liquid to travel from container interior to pouring hole.
in order to provide for entry of air into the container to replace the liquid being poured therefrom, a breather duct 41 is provided by a groove extending from the bottom of the plug to egress port 42 communicating with atmosphere when the plug is in open or pouring position, as indicated in Fig. 2. When the plug is in a retracted or closed position, shown in Fig. 1, port 42 is disposed within the container and sealed from atmosphere. The duct 41 is formed in the wall of the plug adjacent the lowermost part of opening 35', so that the bottom of duct All lies in approximately the same horizontal plane as a portion of opening 35.
The plug is formed with a recess, as indicated by reference numeral 47, adjacent but spaced downwardly from its upper end so that it is entirely within the bottle when the plug is closed, as shown in Fig. 1. Recess 47 has an oblique wall 48 disposed at about a 60 angle from which projects spout 49 disposed at about a 45 angle to the central axis of plug 22. The inside diameter of spout 49 is considerably less than bore 32. The terminal of spout 49 is formed with a curve 50' to reduce tendency to drip. The larger diameter of bore 32 as compared with spout 49 insures that upon completion ofpouring, the liquid contained in pouring spout 49 is forced back into bore 32 and thence into the con tainer interior by reason of the atmospheric pressure exerted at the pouring lip. Additionally, the curved edge orifice 50 assists in preventing spillage or dripping upon completion of pouring.
Normally, the bottle is substantially inverted when pouring. Upon completion, the user puts the bottle back to an upright position and the liquid drains from bore 32 to the container interior by gravity. Atmospheric pressure forces liquid trapped in pouring spout 49 interiorly to the bore and spillage and dripping is thus effectively prevented.
In operation, the closure is placed on a bottle or the like and may be sealed as by a stamp 24 to prevent unauthorized opening of the container. The user may break the seal and pull plug 22 upwardly, thereby exposing breather orifice 42 and pouring spout 49 to atmosphere, as shown in Fig. 2. Upon inversion of the container, fluid will flow through bore 32 outwardly through spout opening 50 while air is replaced through orifice 42 and duct 41. It is noted that opening 35 of bore 32 is enlarged and lies in part in substantially the same hori- Zontal plane as the bottom of duct 41, thus facilitating pouring.
Upon completion of pouring, the container is moved to a generally upright position and the fluid within bore 32 flows back .into the interior of the bottle. The fluid trapped in the pouring spout 49 does not drip by reason of the relative angles and diameters of the ports and curved edge 50.
Although the foregoing invention has been described in some detail by way of illustration and example for purposes of clarity of understanding, it is understood that certain changes and modifications may be practiced within the spirit of the invention and scope of the appended claims.
