COMBINED COUPLING AND CLOSURE FOR DISPENSING CANISTERS Filed Nov. 29, 1963 jflzzfzzzi a/ gag/m, @KKW United States Patent 3,186,537 CONEEED COUPLEWG AND LOSURE Fill?! DlSlENSlNG QANKSTERS Edgar F. Qollins, Wilmette, ill, assignor to Stone Qontainer Corporation, Chicago, lllh, a corporation of Illinois Filed Nov. 29, 1963, Ser. N 326,897 5 Claims. (ill. ZZZ-48d) This invention relates generally to canisters for dispensing granular food products and more particularly, relates to a combined coupling and closure device for use with dispensing canisters of the character described which enables a pair of such canisters to be nested one on top of the other for shipment, storage and display as a unitary assemblage.
Nested or stacked canisters, each of which contains a granular food product, such as, grated cheese, condiments, or the like, have been utilized heretofore with recognized advantages. In practice, it is contemplated that the nested canisters will be separated and used individually; consequently, each canister must have means for dispensing the granular contents and some manner of closure for the dispensin' means when the contents are not being dispensed. Various dispensing and closure means for this type of canister are known, such as the well known dredge top. Top realize a nested or stacked assemblage of such dispensing canisters, resort is had to some manner of separate coupling device which will hold the pair of canisters in nested assembly and permit their separated for dispensing the contents of canisters.
A primary object of the invention is to provide a novel coupling and closure device of the character described which is characterized by structural features which enable the device to function both as a coupling member for nesting the dispensing canisters and as a dispensing means and closure for one of the canisters after they are separated.
Another important object of the invention is to provide a coupling and closure device of the character decribed which is formed as an integral ring member having oppositely opening circular skirts for coupling a pair of dispensing canisters together and a transverse wall intermediate the open mouths of said skirts capable of functioning as a dispensing means and closure for one of the canisters by means of selective rotation of said device on said one canister.
A further object of the invention is to provide a novel device of the character described which is economical to manufacture and install; which is capable of being used on commercially available dispensing canisters without requiring modification of the canister; which can be used advantageously with a large variety of different canister constructions; and which is simple and easy to install and use.
The foregoing and other objects of the invention will become apparent from the ensuing disclosure in which a preferred embodiment has been described in detail in the specification and illustrated in the accompanying drawing. It is contemplated that minor variations may be made in the size, arrangement, construction and proportions of the several parts thereof without departing from the scope or sacrificing any of the advantages thereof.
In the drawing:
FIG. 1 is a side elevational view showing a pair of dispensing canisters coupled together by means of the combined coupling and closure device embodying the invention.
FIG. 2 is a sectional view taken along the line 22 of FIG. 1 and in the general direction indicated.
FIG. 3 is a top perspective view of the device embodyice ing invention with a portion broken away to shown cross sectional details.
FIG. 4 is a sectional View taken along the line 44 of FIG. 1 and in the general direction indicated.
Referring now to the drawing, the combined coupling and closure device embodying the invention is identified generally by the reference character Ztl in FIG. 3. As will appear more particularly from the ensuing dis closure, the device 2! is capable of coupling together a pair of dispensing canisters 22 and 24 in a nested or stacked assemblage one on top of the other, as seen in FIG. 1. Each of said canisters Z2 and Z4 is representative of a type of a conventional package for dispensing granular foods, such as grated cheese, condiments, or the like, and the canisters are generally similar in construction. Such a canister has an elongated cylindrical sleeve as of cardboard, sheet metal or other suitable material providing a circumferential wall open at opposite ends thereof. According to the invention, it is contemplated that the bottom end of each of the canisters will be closed off in a conventional manner, such as, by a circular metal plate providing a marginal head or flange 28 which is crimped or otherwise secured around the marginal lip of the open bottom end of the sleeve 26. The bead or flange is slightly larger in diameter than the outside diameter of the sleeve.
Referring to FIG. 4, the open upper end 29 of sleeve 26 of the upper canister 22 is closed by a dish-shaped circular metal plate 39 having a marginal bead 32 crimped over the marginal lip of said open end. The plate 3% has a circular opening 34 therethrough and a segmentshaped knock-out section 3 Engaged in the hollow of said plate 353 is a conventional dredge top 38 with an opening 39 and a second opening which correspond respectively to the opening obtained when section 36 is removed and opening 34. The dredge top 33 is rotatable selectively about the depending in 48 integral with top 38 which extends through a suitable medial opening in plate 3% to open and close the canister 22. The construction of canister 22, as described, is typical, but it can vary as to the means for dispensing materials therefrom without interfering with the invention.
Referring to FIG. 2, it will be seen that the open upper end 52 of the sleeve 2-6 of canister 24 has a circular metal plate id of dish-shaped configuration secured across the end 42 by means of the peripheral flange 45 engaged around the marginal lip 46. The plate 44 forms a cover or lid for said end 52 and has a knock-portion 46 to provide a large crescent-shaped opening, for instance, and a series of smaller openings 43 for dispensing smaller quantities of the contents of canister 24.
The device 2% embodying the invention preferably is molded as an integral structure of a suitable plastic material such as polyethylene, however, other materials such as metals, also would be feasible. The device Ztl comprises an annular ring having a first skirt 553 and a second skirt 52., said skirts opening in opposite directions. Each skirt has a circular groove 54 in the internal circumferential surface thereof and spaced inwardly a short distance from the end face 55 of the skirt. Inside the ring is a transverse wall 58 which functions as a dispenser top or lid. Referring to FIG. 2, it will be seen that the dispenser top 58 is connected to the ring by means of a short downwardly slanted section 59 so that the lid or top 58 is spaced to one side of the transverse center line of the ring and surrounded by the skirt 52. There results also an annular recess 61 between the wall 58 and skirt 52 toward which the groove 54 in skirt 52 opens.
Referring to FIG. 2, to nest the canisters 22 and 24, the bottom end of supper canister 22 has the bead 28 thereof engaged in the groove 54 of skirt Si) which is at the upper end of the coupling device as shown in PEG. 2.
' the same.
The canister 24 has its upper end received in the skirt 52 with bead or flange 45 engaged in the groove 54 of skirt 50. The dispenser Wall 58 is engaged directly upon the plate 44, Further, the wall 58 has a pair of openings 6t) and 62, opening 62 being larger than opening 60. Each of the skirts t and 52 are made sufficiently resilient to permit ahead 28 or 45 to be snapped into the appropriate groove 54. t i
The canisters 22 and 2 5- are shown nested in FlG. 1. When canister 22 is separated from the ring device 243, the device 29 remains installed on the bottom canister 24. By rotation of the device 2%, each of the openings 69 and 62 can be aligned selectively with an opening in It will be noted that the device 2!} can be used with different structures of dispenser packages since the Wall 58 provides a separate dispenser top for the bottom canister of the nested pair. Consequently, the top canister 22 can have any kind of dispenser top so long as the bottom end of this canister can be engaged in the skirt 5h. The lower canister 24 requires only a top cover or lid plate 44 either with or without dispensing openings. Where no such openings are provided, the user can punch his own holes to align with the openings so and 62 of the dispenser top Wall 58. Also, the upper canister 22 can be made with an upper end wall similar to plate 44 and without a dredge top. When canister 24 is exhausted, device 20 can be removed and installed'on canister 22 overlying such anend plate. Thus, device Ziicould be used also for two identical canisters 24. I
It is believed that the invention has been described in suflicient detail to enable the skilled artisan to practice In the appended claims, the invention has been pointed out in language intended to be liberally 7 4 construed commensurate with the advance in the arts and sciences contributed thereby.
