signments, to American Can Company, New York, N. Y., a corporation of New Jersey Application-February 18, 1954, Serial No.'411, 14 1 Claims. (Cl. 22144) :casing having a circular interior opening'through which the articles are dispensed. A means is provided on the interior wall of the opening for decreasing slightly the diameter of the opening and for supporting the stack'of nested articles. This means, which may comprise a plurality of equally spaced projections or lugs, serves to prevent free movement of the stack through the opening and also as a support for the stack.

It is common practice to form these projections integrally with the inside wall of the casing so that the casing'will support a stack of cups of only one diameter. However, in some cases it is desirable that the same casing support cups of less diameter than those to be supported by the fixed or jections.

Heretofore it has been proposed to reduce further the permanently attached proinside diameter of such a casing at the dispensing end thereof by providing a continuous ring adapter which itself has inwardly projecting supports. This adapter 'has a projection provided on its exterior surface which rests on the permanent projections formed on'theinterior surface of such casing, while its interior surface is provided with projections which reduce its diameter slightly. When this adapter is in operating position in the casing it serves to reduce further the diameter of the opening with the result that cups of less diameter than those supported by the permanent projections on the casing may be used.

Thestructure just described comprises in effect two separate casings, each with interior projections adapted to support cups of different diameters. In use, the smaller shell or adapter is placed inside the larger casing .and supported by the projections on that casing when it is desired to use the dispenser for cups of less diameter.

I have found, however, that the same result can .be obtained with a considerable saving in tool and material costs, by providing separate insertable and replaceable adapters designed to be supported by and between the permanent projections formed on the casing.

An object of the invention, therefore, is to provide a dispenser comprising a casing having permanent projections associated therewith for supporting cups of a predetermined diameter and being so constructed as to receive separate movable adapters between the permanent projections, which adapters reduce the diameter of the opening in the casing to a greater extent than do the permanent projections so as to support cups of less diameter than those supported by the permanent projections on the casing.

A further object is to provide an adapter arrangement of the character described which is made with a minimum of tool and material cost.

Pa., assignor, by msne as- Patented Mar. 10, 1959 Another object is to provide an adapter construction which may be readily inserted, in the casing from the dis charge end thereof.

Other objects and advantages of the invention will readily apparent from the following description and accompanying drawings wherein:

Fig. 3 is a section taken on line III-III of Fig. 2 looking in the direction of the arrows.

Fig.5 vis a top view of the adapter shown in Fig. 4.

Fig. 6 is a vertical section taken on line.VI-VI of Fig. '4 looking in the direction of the arrows.

Referring .to the drawings, a shell or casing '10, which may have any suitable external configuration, serves as a support 'for the cups to be dispensed. Thecasing is here shown as provided with a top wall 11 formedintegrally with the casing, and with an opening 12 at its bottom. The casing shown is generally cylindrical and the opening 12 is circular. Aportion 13 projects from the casing vand is provided with a flat surface 14. This surface is adapted to engage and 'be placed against an- .other Jflat surface .such as a wall. The casing may be secured to the wall .by screws (not shown) .which pass through the openings 15 and 16' provided in the flat surfacelel, or by any other suitable means.

A plurality of inwardly projecting flat-faced supports 17 are spaced equally around the interior wall. of the casing. Each of these projections comprises an outwardly and downwardly inclined surface or shoulder 18 which serves to support the brim of the lowermostcup in the stack. The lowermost edge of surface 18 coincides with the upper edge of a vertical surface 19 which extends nearly to the bottom of the casing. As here shown,.the lower edge of surface19 coincides with'the upper edge of anfinwardly inclined surface 20 which extends to .the bottom edge 21 of the casing '10. In practice it is preferred to use four such projections equally spaced from each other. With this structure the projections 17 support a stack of cups ofpredetermined .23 designed to conform to the curvature of the inner wall of casing .10 and its width is sufiicient to extend between two adjacent projections 17'. The opposite side edges of the adapter are beveled as indicated at25. These edges interfit with beveled vertical sides of projections 17.

In practice the adapter is slid upwardly from the bottom of the casing with the beveled edges 25 of the adapter engaging with and interfitting beveled edges 26 on the sides of projections 17. In order to provide flexibility and resiliency for the side walls of the adapter, slots 27 extend from the top edge thereof downwardly toward, but terminating short of the bottom edge thereof. These slots are formed in the wall of the adapter between the edges 24 and the cup-supporting portion thereof and thereby provide a flexible portion 270. The cup edges 26 formed at the 31 and an inclined portion 32 the lower edge of the vertical portion 31 to edge 33 of the adapter.

;It will be noted (Fig. 6) that in profile the slanted portion 30 of the adapter extends out a considerable distance from the curved back wall 23 so that when the adapter is in place as shown in'Fig. 2, the portion 30 which supports cups, extends nearer the center of the opening 12 than does the portion 18 of the permanent projection 17. Thus when all the adapters are in place, cups of less diameter than those supported by the permanent projections 17 are supported by the casing in a position to be readily dispensed.

As has been previously stated, the slots 27 allow flexibility of the side edges of the adapter so that when the adapter is in place it has a close fit with the beveled edge portions 26 of the permanent projections 17. To retain the adapters in position against downward displacement extending inwardly from the bottom -in use, laterally projecting ears 34 are provided at the upper outside corner of each of the resilient flexible portions 27a. These ears overlie the upper edges of the adjacent permanent projections 17 Should it be desired to remove the adapters it is necessary only to press the two resilient portions other until the ears 34 are released from the upper edges of the permanent projections 17 and then to push the adapter downwardly until it is free. A construction which permits adapters to be applied and released from a dispenser through the bottom opening is particularly advantageous in cases where the protective cover for the cups is permanently attached to the supporting casings although the invention is not limited to use with such a cover structure.

While only one embodiment of the invention has been shown and described it will be readily apparent that the invention is not so limited but may be any construction defined by the following claims.

I claim:
