Definitions
- This invention relates to dispensing containers for flufied foods, that is, for foods, such as whipping cream, into which have been mixed, under pressure, gases such as carbon dioxide and nitrous oxide, the expansion of which on reduction to atmospheric pressure will cause the food to be flufled or whipped. More specifically, this invention relates to dispensing containers simple and inpensive enough to permit their being discarded after a single use.
- Simple single-use containers have usually been designed for relatively low internal pressures; and for such containers it was convenient to insert the edges of a resilient sealing member under an ordinary crown cap to be crimped to the top of the container. Inasmuch as I employ pressures ranging up to 100 pounds per square inch, such a container is not suitable. I find it necessary to utilize a metal container onto which a metal top is spun or otherwise securely attached. A number of problems then arise as to the manner of assuring a pressure-tight seal while maintaining a simple structure. It is to these problems that this invention is directed.
- One object of this invention is to provide a dispensing container capable of resisting high internal pressure and nevertheless simple in design, and having a minimum number of readily assembled, inexpensive parts.
- Another object is to provide a container with a resilient sealing member and valve so formed that they lock each other in place in the container top.
- Another object is to provide a resilient sealing member which serves not only as a seal but also as a seat for the dispensing valve and, further, as a spring to restore the dispensing valve when displaced and control the flow from the container.
- Another object of this invention is to provide a container with a sealing member which prevents leakage through the top regardless of the degree of deflection of the dispensing valve.
- Another object is effectively to utilize the gas pressure within the container to maintain a seal between the sealing member and the container top even though said sealing member may be distorted by the angular tilt and lateral displacement of the dispensing valve.
- Fig. l is a perspective view showing the general external appearance of the present invention in a preferred embodiment.
- Fig. 2 is an enlarged sectional view showing the detailed organization of the elements which comprise the invention.
- Fig. 3 is an enlarged sectional view showing the relative positions of these elements when the dispenser is being operated by lateral pressure on the outlet valve stem.
- Fig. 4 is an enlarged sectional view of the resilient sealing member or grommet in unstressed condition, prior to its being assembled as shown in Fig. 2.
- my invention comprises a container 11 suitable for dispensing whipping cream into which nitrous oxide or other gases have been mixed under pressure, such container having a top wall 12 sealed onto it at pressure-tight joint 13. Centrally located in top wall 12 is circular opening 14 circumscribed by a stamped or pressed upturned annular flange 15.
- the sealing member or grommet 16 is formed of material, such as synthetic rubber, not injurious to cream and having suflicient resiliency to serve the functions herein described.
- Said member has a tubular bore 17 with an enlarged lower portion 18 to facilitate the dis- 2,704,172 Patented Mar. 15, 19 55 pensing action. Its relatively thin-walled neck portion 19 extends through and is held tightly in flange 15 and terminates in an enlarged collar portion 20 which extends over said flange.
- Below said top wall 12 said sealing member has a greatly enlarged body portion 21, which is tapered upward and outward to an extended thin flexible sealing edge 22.
- the upper face 23 of said body portion 21 is slightly concave or cupped before assembly; that is, when it is unstressed. Its lower face 24 serves as a seat for the head portion 25 of tubular stem valve 26.
- Valve 26 has at its lower or inner extremity imperforate head portion 25 of enlarged diameter, from which rises tubular stem 27 with rectangular ports 28 adjacent head portion 25. While circular holes would serve as ports, the rectangular shape permits a greater port area and hence an increased rate of flow. Stem 27 passes through and beyond the body portion 21, neck portion 18 and collar portion 20 of sealing member 16, said stem 27 fitting tightly in and slightly stretching tubular bore 17. Immediately above collar portion 20, stem 27 is sharply enlarged to form external shoulder 29, whose diameter is sufliciently less than that of top wall opening 14 to permit assembly in the manner hereinafter described.
- stem 27 curves or tapers inward and upward to tip 30, which has an external diameter sufliciently small to permit its insertion through tubular bore 17, and which tip is cross-slotted to shape the dispensed cream in the manner of a confectioners tip.
- the container is readily assembled as follows: Collar portion 20 of sealing member 16 is forced through opening 14 from the inner side until it emerges above flange 15, and neck portion 19 fits in opening 14. Tip 30 of valve 26 is then inserted through enlarged bore 18 of sealing member 16, and pushed by head portion 25 until it seats against lower face 24 of the sealing member, at which point shoulder 29 will have been forced through and emerged out of the upper end of collar portion 20 and be locked in place by it.
- the container 11 is then filled with cream, the top 12, assembled with valve 26 and sealing member 16, is sealed on at joint 13, and gas is inserted under pressure through the valve.
- tubular bore 17 of sealing member 16 fitting tightly against stem 27 of valve 26, will form a pressure tight seal between member and valve.
- stem 27 so enlarges neck portion 19 of the seal ing member as to make a seal between it and the annular flange of top wall 12.
- valve head portion 25 When lateral pressure is applied to the valve stem above shoulder 29, such pressure is resisted by a rotational deflection of the sealing member primarily in the region of its neck and collar portions 19 and 20.
- the flexible sealing edge 22 is, however, held tightly against the container top 12 by the pressure within the container, and is not puller away regardless of the degree of rotation of the other portions.
- one side of valve head portion 25 will be displaced from seat portion 24 ofthe sealing member as long as the lateral pressure on the valve stem is maintained.
- the increased diameter of bore 18 at the lower end of the sealing member permits the flow of the food through all the ports 28 simultaneously. Further, this increased bore 18 results in a necking down of the sealing member subjacent flange 15 of the container top.
- an elastic sealing member adapted to seal such valve within the opening of such container wall, said elastic sealing member comprising an annular valve seat portion, a tubular sleeve portion extending outwardly therefrom and having an outer sealing surface adapted to abut sealingly against such container wall opening and an inner sealing surface adapted to grasp elastically and sealingly around such valve at the level of its passage through the opening in the wall of such container, and anxnlarged upwardly presented concavely cupped annular face at the base of said sleeve portion, said face having an unsecured peripheral edge, said face being adapted to be stressed and flattened as a suction cup against the inner side of such container wall and retained in sealed relation thereagainst by gas pressure within such container, whereby on insertion of such gas pressure its unsecured peripheral edge is held sealed against such container wall regardless of the tilt of its sleeve portion attendant
- an elastic sealing member adapted to seal such valve within the opening of such container wall, said elastic sealing member comprising an annular valve seat portion, a tubular sleeve portion extending outwardfy therefrom and having an inner sealing surface adapted to grasp elastically and sealingly around the stem of such valve at the level of its passage through the opening in the wall of such container, and an enlarged upwardly presented concavely cupped annular face at the base of said sleeve, said face having a gradually tapering unsecured peripheral edge, said face being adapted to be stressed and flattened against the inner side of such container wall and retained in sealed relation thereagainst by gas pressure within such container.
- an elastic sealing member adapted to seal such valve within the opening of such container Wall
- said elastic sealing member comprising an annular valve seat portion, a tubular sleeve portion extending outwardly therefrom and having an inner sealing surface adapted to grasp elastically and sealingly around the stem of such valve at the level of its passage through the opening in the wall of such container, an enlarged upwardly presented concavely cupped annular face at the base of said sleeve portion, and a collar portion enlarged radially from the upper portion of said sleeve and having an outer diameter greater than the opening in the wall of such gontainer, the length of the sleeve portion between its base and the collar portion being no greater than the depth of the opening in the container wall, whereby the detention of the collar portion against the outer side of the wall opening maintains the sealing member flattened against the inner side thereof.
- a tilt-opening valve assembly for gas-pressure containers adapted to be sealedly retained in an opening of a wall thereof, comprising a rigid tubular stem valve member having a discharge spout exterior the container, a valve head within the container, a stern port adjacent said valve head, and an inwardly presented shoulder formed annularly inwardly of said discharge portion, in combination with an elastic sealing member adapted to seal such valve within the opening of such container wall, said elastic sealing member comprising an annular valve seat portion, a tubular sleeve portion extending outwardly therefrom and having an inner sealing surface adapted to grasp elastically and sealingly around the stern of such valve at the level of its passage through the opening in the wall of such container, an enlarged upwardly presented concavely cupped annular face at the base of said sleeve portion, and a collar portion enlarged radially from the upper portion of said sleeve and having a lower annular margin presented abutting the outer side of the wall of such container, said collar portion further having an upper
