CAP OR CLOSURE FOR CONTAINERS Filed Dec. 8, 1958 INVENTOR.
United States Patentlice 3,067,916 Patented Dec. 11, 1962 3,067,916 CAP R CLOSURE FOR CONTAINERS Nathan B. Lerner, Chicago, Ill., assigner to W. Braun Co., Chicago, Ill., a co-partnership Filed Dec. 8, 1958, Ser. No. 778,693 1 Claim. (Cl. 222-519) This invention relates to a cap or closure for containers and the like.
One of the objects of this invention is to provide a cap or closure for containers which effectively seals the container and which is provided with a spout opening which is in a plane substantially at right angles to the longitudinal axis of the closure and the container.
Another object of this invention is to provide a cap or closure of the foregoing character which is used for dispensing liquids from containers.
Another object of this invention is to provide a cap or closure which is held captive to the container, which may be integrally formed or molded in'a single operation, which is inexpensive to manufacture and which is easy to use.
Another object of this invention is to provide a cap or closure which serves to seal the container and which is provided with a laterally disposed discharge spout opening at substantially right angles to the longitudinal axis of the cap and the container so that the contents of the con# tainer may be discharged by a slight tilting of the container.
Another object of this invention is to provide a cap or closure of the foregoing character which provides a corking closure forl the container.
In the drawings: i
FIGURE 1 is a front elevational view of the closure or cap applied to the container. A
FIGURE 2 is a cross-sectional view of FIGURE 1 taken on lines 2 2 of FIGURE 1 with the closure or cap in sealing position.
FIGURE 3 is a view similar to FIGURE 2 with the closure or cap in position to permit the contents of the container to be discharged through the spout of the closure or cap.
FIGURE 4 is a perspective view of the closure or cap.
FIGURE 5 is a cross-sectional view similar to FIGUR 2 with a modified cap construction, and
FIGURE 6 is a cross-sectional view of a modied cap construction.
The structure shown in FIGURES 1 to 4 inclusive will be rst described. The cap or closure 10l is molded preferably of a resilient plastic material, such as polyethylene, plasticized nylon, plasticized acrylic resins, plasticized vinyl resins, and the like, and is adapted to lit over the neck of any conventional bottle or container for dispensing the contents from the container.
As illustrated, the conventional container generally indicated at 12 has a neck 14, a portion of which is provided with a helical thread 16. The neck above and below the threaded portion is designated at 18 and 20 respectively and same has a smooth surface, not being threaded. The neck is provided with the usual discharge opening 22 communicating with the interior of the bottle or container through which the liquid contents of the container is discharged. The container 12 just described is conventional in the art and no invention is claimed therein.
The cap or closure 10 forming this invention comprises a tubular body portion 24 which is provided with an internal helical shaped thread 26 to engage the helical thread 16 of the neck 14 of the container. The upper part of the tubular body portion 24 is slightly enlarged as at 28 to provide a wall surface of a slightly greater diameter than the tubular body portion 24. The lower portion of the tubular body portion 24 is provided with an inwardly extending lip or bead 25 which extends inwardly of the edges of the thread and said lip or bead 25 will engage the lowermost portion of the threads 16 to hold the cap 10 captive on the neck of the container and prevent removal therefrom. The cap may however be rotated sutilciently to permit raising the cap suliiciently to unseal and uncover the discharge opening 22 of the container. While the inner periphery of the lip or bead 25 is inward of the outer edges of the threads 16 of the neck 14 of the container, the character of the plastic material from which the cap is made will permit the cap to give suliciently to permit the lip or bead 25 to pass over the threads when initially securing the cap to the neck of the container. If a removable cap is desired, the lip or bead 25 may be eliminated.
Extending across the top of the cap is a top portion 30 which also extends horizontally forward of the enlarged annular portion 28 and also inclines or tapers inwardly as at 32. The enlarged tubular wall portion 28 of the body also extends forwardly and tapers inwardly at 34 and is joined by a forwardly extending lower lip 36 to form a spout generally indicated at 38 having a generally rectangular shaped opening 40` which communicates with the interior of the cap.
It will be seen that the discharge outlet 4t) of the spout 38 is sidewise of the body of the cap, that is, the spout outlet 40 is in a plane substantially at right angles to-the longitudinal axis of the closure. The longitudinal axis of the cap is designatedl -by the line A-A in FIGURE 2. This feature is Very important since by tilting the con'- taner, the liquid contents are funneled to the discharge opening of the spout and is discharged in a plane at approximately right angles to the longitudinal axis of the closure, as well as to the container. This permits pouring through the spout by a slight tilting or inclination of the container from the vertical, as contrasted to the horizontal pouring position necessary in prior art structures where the discharge opening is through the top of the closure, i.e. where the discharge outlet of the closure is in a vertical plane parallel with the axis ofthe closure and the container, such as shown in Patent No. 2,463,152 which is directed to a cap for a collapsible tube and is not applicable for liquids.
The top portion 30 of the cap is provided with a centrally positioned annular depressed portion 42 which forms an inner annular boss 44 extending into the cap interior below the top. The boss'44 is adapted to make a seal tight fitting engagement with the top of the neck of the container to close the neck when the cap is in closed position on said neck to prevent discharge of the liquid from said container, as best shown in FIGURE 2.
The enlarged body portion 28 of the cap is provided with a transverse opening 46 communicating with the interior of the cap. When the cap is in closed position as shown in FIGURE 2, the opening 46 is below the top of the neck of the container and is closed by the upper wall of the neck of the container so that in eiect the opening 46 is sealed when the cap is in closed position. However, when it is desired to discharge the liquid from the container, the cap is rotated slightly to its raised position, as shown in FIGURE 3, and in this position the annular boss 44 of the cap is displaced from the upper edge of the neck and the transverse opening 46 is above the neck of the container to permit air to enter into the cap, and by tilting the container the liquid in the container is discharged through the spout 38 of the cap.
With applicants arrangement of the air opening 46 in relation to the spout 38 and sealing means 44, the air opening is uncovered simultaneously with the unsealing of the discharge outlet of -the container, thus by a slight turning of the cap the cap is in a position to be used as a spout for the discharge of the contents of the container. After thus used, the cap may be rotated to the position as shown in FIGURE 2 to seal the container..
The cap construction shown in FIGURE 5 is similar to the construction shown in FIGURES 1 to 4 and will not be described except for the difference. In this construction the top portion 30 of the cap is provided with a downwardly extending annular boss 44 which extends below the plane of the discharge end of the spout 38 and said boss 44 extends into the neck of the container a greater distance than the distance of the boss 44 shown in FIGURES 1 to 4 inclusive. This construction is used preferably on liquid bottles or containers where a corking effect is desired and where it is desired to discharge the liquid rnore slowly. The rate of discharge may be more effectively controlled dependent on the position of the boss 44 in relation to the neck, for example, by rotating the cap slightly to raise it in relation to the outlet end of the container a smaller passage is provided for the outlet of the liquid from the container through the spout which may be increased by rotating the cap to a greater degree.
The modication shown in FIGURE 6 twill now be described. The container 50` has a neck 52 provided with an outwardly extending beaded portion 54. The cap or closure generally indicated at 56 comprises a tubular body portion 5S, the lower end of which is provided with an inwardly extending lip or bead 60 adapted to engage the bead 54 of the container to prevent removal of the cap and hold same captive to the container. Extending inwardly from the body is a top portion 62 which continues downwardly to form an annular wall 64 parallel with the tubular body portion 58. The annular wall 64 continues to form a horizontal wall 66. The cap is provided with a discharge spout 68 similar to that previously described.
The tubular body 58 is provided with an air opening 70 below the plane of the spout 68.
The cap shown in FIGURE 6 is applied to the neck of the container so that the annular wall 64 is received lwithin the neck of the container and engages same. The annular wall 64 and horizontal wall 66 acts as a cork for the container. The cap shown has a sliding tit with the neck of the container and by raising the cap so that the horizontal wall 66 clears the upper portion of the neck, the discharge opening of the container is unsealed so that the liquid Vfrorn the container may be poured through the spout 68. If desired, the cap shown in FIGURE 6 may be provided with internal threads to engage the threaded neck of a container, similar to that shown in the previous gures, in which ease the cap is rotated with respect to the neck instead of sliding same, as shown.
While this invention in the forms shown is best suited for dispensing liquids of any viscosity from a container, it may also be used for dispensing pastes of any character, and where so used the air opening in the cap may be eliminated.
The cap shown in the drawings may be integrally molded in a single molding operation and requires no assembly of parts. It serves to effectively seal the container and permits the contents to be discharged through a spout which extends laterally and forwardly of the cap. It is economical to produce and very efficient in operation.
It will be understood that various changes and modiications may be made from the foregoing without departing from the spirit and scope of the appended claim.
A one piece cap for a container for material, which container has a threaded neck portion and a discharge opening with an inside annular wall coextensive with the internal diameter of the neck, said cap having a continuous and uninterrupted tubular body provided with a continuous and uninterrupted thread cooperating with the threaded neck, said tubular body having an enlargement at the upper end, a substantially at top wall portion extending across the top of said enlargement, said top wall portion and said enlargement continuing laterally and forwardly of said tubular body and converging towards its forward end to form a laterally extending discharge spout which extends laterally of said tubular body and laterally beyond any portion of said tubular body with the discharge opening of said spout being in a plane substantially at right angles `to the longitudinal axis of said body, said at top wall portion is of uniform thickness and extends laterally outward to form the top of the spout, said top wall portion has an integrally formed central sealing projection projecting into the discharge opening of the container below the top of said discharge opening to engage the inside annular wall of the neck inwardly of the discharge opening for closing said container when said closure is in closed position.
