3 Claims. (Cl. 220-14) This invention relates to scaling devices for reand removed and through which access to the frigerating cabinets such as are commonly emcans is had for removal of their contents. This ployed at soda fountains for dispensing puropening is customarily closed by a cover of any poses, such cabinets being adapted to contain one preferred construction, not shown.

The device Fig. 2 is a plan view of the construction shown maintains the cans in position and in the case in Fig. 1; of paper cans, prevents their collapsing, forms a Fig. 3 is a plan view of my novel sealing detight seal around each can, and also a tight seal vice; and. with the surrounding walls of the chamber so Fig. 4 is a sectional view taken on the line that the chamber is effectively sealed against the 44 of Fig. 3. atmosphere and circulation of air into and out of 50 Referring to the drawing more in detail, referthe chamber is precluded while, at the same time, ence character 5 indicates generally the cabinet, the dropping of particles of ice cream or other 6 and l a plurality of cans set side by side therein, solid matter around the cans is prevented. When and 8 the opening in the top of the cabinet it becomes necessary to replace the cans, the dethrough which the ice cream cans are inserted vice may be readily removed by pulling upwardly on the handle to detach it from the cans and the chamber.

In case the cabinet be constructed to receive single cans instead of doubles, the sealing device may be modified to comprise a single instead of a double opening, in which case the flexible marginal flange will be of uniform width entirely around the opening.

The details of construction in other particulars may obviously be varied from those shown and described without departing from the spirit of the invention as defined in the following claims.

I claim:

1. A sealing device for refrigerating cabinet comprising a body formed of flexible elastic material provided with a plurality of openings therethrough, each shaped and proportioned to snugly and sealingly embrace the outer surface of the upper portion of an ice cream can, said openings each being tapered outwardly from top to bottom, said body being provided with a marginal tapered flange projecting outwardly and upwardly around the body and adapted to engage and conform to the walls of the surrounding chamber to provide a seal for said chamber.

2. A sealing device for a refrigerating cabinet comprising a body formed of flexible elastic material provided with a plurality of openings shaped and. proportioned to snugly and sealingly embrace the outer surface of the upper portion of an ice cream can and provided with a tapered flexible flange extending at an angle to the plane of the body around the periphery thereof and adapted to engage and conform to the walls of the surrounding chamber so as to provide a seal for said chamber.

3. A sealing device for a refrigerating cabinet comprising a body formed of flexible elastic material provided with an opening shaped and proportioned to snugly and sealingly embrace the upper portion of an ice cream can, said opening being tapered outwardly from top to bottom, said device being provided at its upper edge with an outwardly and upwardly extending marginal flange, said flange being tapered toward its outer edge and being sufficiently flexible to engage and conform to the walls of the surrounding chamber so as to provide a seal thereofor.
