POURING AND CLOSING CAP FOR RECEP'IACLES Filed April 20, 1938 16.5. le'l T z Patented Mar. 3, 1942 are POURING AND CLOSING CAP FOR RECEPTACLES Application April 20, 1938, Serial'No. 203,130
7 Claims. (Cl. 65-31) My invention relates to caps, covers, or the like, for useon bottles, jars, pitchers, and similar fluid containing receptacles, designed normally to close the receptacle to seal the contents thereof againstcontamination, but adapted to be opened by manual operation to permit pouring of the contents from the receptacle. My invention has particular reference, although not necessarily, to syrup pitchers. It is a purposeof my invention to provide a cap which, as applied to a syruppitcher or similar receptacle, is adapted to be manually opened to permit pouring of the liquid from the receptacle, and when released to automatically close in a manner to prevent dripping of the syrup or other liquid from the pitcher.
It is also a purpose of my invention to provide a cap for receptacles which is structurally characterized by its simplicity, durability, low cost of manufacture, easy mode of assembly and disassembly of its parts, and the form of its body and closure member, which lend themselves to being constructed of any suitable composition material, as well as metal.
I will describe only one form of pouring and closing cap for receptacles, embodying my invention, and will then point out the novel features thereof in claims.
In the accompanying drawing:
Fig. 1 is a view showing in perspective one form of cap embodying my invention in applied position on a receptacle.
Fig. 2 is a view on an enlarged scale showing the cap in top plan.
Fig. 3 is a vertical sectional view taken on the line 3--3 of Fig. 2, with the cap in applied position on the receptacle, and with the closure member of the cap in closed position.
Fig. 4 is a view similar to Fig; 3 closure member in open position.
Fig. 5 is a vertical sectional view taken on the line 5-5 of Fig. 3.
Fig. 6 is an enlarged sectional view taken on the line 63 of Fig. 3.
showing the In carrying out my invention, I provide a hole low body B of cupped form so as to have an arcuately curved outer or upper side on which a closure member C of like curvature is adapted to slide in a groove l5. This groove is of U-form in cross section and extends from one edge of the body B over to a pouring spout it formed in the body adjacent its opposite edge. The closure member C is in the form of a strip permanently curved to the same longitudinal curvature as the groove l5 so as to lie flat therein and to be slidable on the body to open and closethe pouring spout IB.
To prevent dripping of any liquid poured from the spout Hi, the inner edge lfi (Fig. 2) of the curved part of the spout is on any radius different from that of the curved end edge 11 of the closure member, and, as shown in Fig. 3, the upper surface of the spout is in the same plane as the bottom surface of the groove l5 so that in the closed position of the closure the spout is sealed against the leakage of liquid therefrom.
Thatend of the closure member C opposite from the spout-closing end is formed with, or has fixed thereto, an extension l8 which projects laterally therefrom at an angle suitable for depression by the thumb of the operator for moving the closure member to a position in which the spout I6 is open. Normally the closure member is urged to spout-closing position by any urging means such as the coiled spring l9. This spring,
at its upper end, is secured in an ear 20 on the underside of the closure member C, and at its lower 'end to a tongue 2| on a plate 22.
To accommodate the ear 20 in its movement with the closure member as the latter is moved to or from open or closed position, the body-B is formed with a slot 23. Extending downwardly from the opposite edges of this slot '23 area pair of side walls 24, tapered in width and connected at their wide ends by a wall 25. The walls 24 and 25, which are formed integral with the cap body, as will be understood, cooperate with the plate 22 to form a housing for the spring [9 and to prevent the passage of fluid from the receptacle upon which the cap is mounted outwardly into the slot 23. Thus, the closure member and spring are protected against contamination by the liquid, or vice versa, and in the instance of syrup, it is prevented from-entering the groove l5 and impeding operation of the closure member. The plate 22 is formed at its edges with lips 26 which overlap the edges of the walls 24 and 25 so as to effectively close the housing.
'With the spring [9 associated with the closure member C and the plate 22, it will be manifest that the spring not only urges the closure member to closed position with respect to the spout It, but it urges the closure member downwardly in the groove to maintain the member within the groove at all times, and, yet, allows the member to be slid to open or closed position. By urging the closure member downwardly itis pressed against the spout in its forward sliding more, the spring serves to maintain the plate 22 in housing-forming position on the walls 24 and 25. Manifestly, the plate 22 can be pulled ofi1" of the walls and the spring I9 disconnected to allow removal of the closure member when necessary for purposes of cleaning.
The cap body B for a portion at one end of the groove I5, is indented to form a secondary groove 21 having a lower end wall 28 and an upper end wall 29 connected by a curved bottom wall 30. The wall 29 is divided to form a slot 3| which provides a vent port to admit air to the receptacle and thus facilitate pouring of the contents of the receptacle from the spout IS. The closure member at its point of junction with the extension I8 is formed with a tongue 32 movable in the secondary groove 21 and provided with a wedge-shaped projection 33 which constitutes a valve for the vent 3|. 7
As it will be observed from the consideration of Figs. 3 and 4, the valve 33 closes the port 3| when the closure member C is in closed position with respect to the spout l6. Conversely, when the closure member is in open position the valve 33 is displaced from the port 3| to open the latter and thus admit air to the receptacle concurrently wtih opening of the spout l6. Not only does the valve 33 function to close the vent 3|, but it coacts with the wall 29 to limit movement of the closure member to closed position under the action of the spring IS. The extreme open position of the closure member is defined by the underside of the extension l8 abutting the wall 28.
The cap body B may be constructed in any suitable manner to permit of its temporary or permanent attachment to a receptacle. In the present instance, the cap is shown applied to a conventional form of syrup receptacle R provided with an externally threaded neck 34. The cap body is formed with an internally threaded collar 35 which permits screwing of the cap on the receptacle. To convert the receptacle into a pitcher, the cap body may be formed with a radial projection 36 into which is screwed a handle 37.
With the cap applied to the receptacle as described and the closure member C in closed position as illustrated in Fig. 3, the spout I6 is closed and the vent port 3| likewise closed by the valve 33 so that the contents of the receptacle are sealed against contamination. To pour the contents of the receptacle therefrom, the handle 31 is gripped and the receptacle tilted and, concurrently with or after such tilting, the thumb of the hand is employed to depress the extension Hi to the position shown in Fig. 4, wherein the closure member is slid rearwardly to open the spout Hi. In this position of the closure member the valve 33 is moved to open the port 3| and thus admit air to the receptacle, thereby causing free pouring of the contents. In this open position of the closure member the extension l8 abuts the projection 36 so that any excessive pressure exerted on the extension l8 will not tend to distort the cap or loosen its connection with the receptacle. This is advantageous particularly where the cap body and closure member are made of a composition material such as Bakelite, and, hence, subject to breakage. As the cap body and the closure member are both made from a single piece of material, they lend themselves to being molded from any suitable composite material.
Although I have herein shown and described only one form of pouring and closing cap for receptacles embodying my invention, it is to be understood that various changes and modifications may be made herein without departing from the spirit and scope of the appended claims.
