(ci. i5-sii 14 Claims.
The invention relates to dish-like containers, and, more particularly, t0 the type embodying single-use removable and readily disposable liners and holders with which said liners are used.
The liner of the present invention and the holder therefor are simple and cheap to con-V struct, and yet are reliable in use.
Such liners and holders are especially adapted for receiving food products, such as ice cream, and
are frequently use'd at picnics, soda fountainsl and other similar places, so that after use the liner may be thrown away and the holder set aside for future use. Usually, the liner is made of waterproof paper suitably folded or pleated to y fit the holder, and is merely dropped into the holder to resi; therein by gravity. l
Liners heretofore used have also been held in place by having a part of the body inserted under the edge of the holder or the like. With this construction, it was necessary to make these liners of some substantial, heavy stock which was difficult to work and more expensive.
.An object, of the present invention is to provide an improved holderand linerconstruction in which the liner may be conveniently detachably connected to the holder so that it will not inadvertently fall out of the holder or be lifted and lock the liner against accidental removal therefrom. In the preferred form of the invention, however, the base is made in the form of a disk underlying the bottom of the liner and reinforces the bottom of the liner against tearing through due to moisture in the material placed in the dish softening the thin paper, and also against the action of a cutting implement should the same be usedto cut the material in the dish..
The liner and reinforcing .base can be secured together at the time 'when they are manufactured, or, if desired, the bottom of the yliner and/ or the base can be provided with an adhesive which will adhere only to a properly prepared coacting out of the holder when food, such as ice cream, is h bottom edge of the liner and forms a resilient rim or ange to cooperate with the holder to lock the liner in place.
The holders for receiving the liners are provided with abutments, preferably in the form of a plurality of spaced projections on the inner side walls adjacent the base which cooperate with the flange on the base of the liner to hold the same against accidental removal from the holder.
This construction eliminates any objectionable flanges, or the like, on the holder which are hard to clean. A Y
Inasmuch as the holders of the present invention are of a relatively simple construction, they may be inexpensively produced, as they can be readily molded from plastic material, or stamped Y from sheet metal.
surface, sothat they can be secured together. Such liners and bases can be easily stacked without adhering to one another, and, when it is de'- sired to use them, `they can be secured together quickly by the user. If dry adhesive is used, the liner and base may be assembled by merely pressing the two dry adhesive surfaces together.
The dishes may be made in any suitable shape, and the liners can be printed with decorative designs, as required. I
To readily remove the liner from the holder, an aperture lmay be provided in the bottom of the holder through which the fingers or a suitable instrument can be inserted and apply outward pressure to the reinforcing base to flex the same and cause it to snap'frcm under the projections. Since the liner is held adjacent the bottom thereof, pressure through the aperture in the base of the holder will readily release it for disposal and/or replacement.
Other features and advantages will hereinafter appear. l
In the accompanying drawing:
Figure 1 shows a top plan View of the receptacle with the liner in place.
Fig. 2 is a longitudinal sectional view, taken along line 2-2 of Fig. 1.
Fig. 3 shows a fragmentary view, similar to Fig. 2, of another form of projection.
Fig. 4 is a view similar to Fig. 3 showing still another form of projection.
Fig. 5 shows an exploded view of the liner and holder thereforjust prior to the liner being in-I serted into the holder.
As shown in the drawing, the receptacle of `the present invention .comprises a dish-shaped therefrom. Adjacent the bottom of the side walls on the inner surface thereof is located the locking -means for cooperating with the liner to hold it in position. While the locking means may be a continuous rib, I have found that a plurality of projections I4 uniformly spaced at intervals around the dish and each providing a shoulder I5 will securely hold the liner in place.
These projections may be formed, as shown in Fig. 2, by a thickened portion of the wall, preferably made integral with the wall, although separate projections secured to the wall can be used if desired. They can also be formed by a lanced finger I 4a bent inwardly to provide a shoulder |5a, as shown in Fig. 3, or by a portion Mb -,of the wall of uniform thickness beingl pushed in to provide the shoulder I5b, as shown in Fig. 4. The latter two forms of holder can be more readily stacked as the projections on one will fit within the recess formed in the outer walls of the next adjacent holder in the pile.
Although the projections may be formed with shoulders on their upper surfaces, I have found that a smoother and easier insertion of the liner is accomplished when'the upper surface I6 of each of the projections I4, Ma and IIb is .inclined upwardly so that it merges with the wall. 'I'his inclined portion serves as a guide and camming means for the liner holding means as will be described.
The holder can be easily stamped from sheet metal or molded from a plastic material, and can be provided with legs, handles or suitable ornamentation as required.
The liner I I is shaped to conform to the holder and has a bottom IIa and side walls IIb. Preferably, itis made of thin paper or the like material. In the illustrated form of the invention, it is blanked out-and pleated around its edges, as shown at I1, so that it lies close to the side walls of the holder. Secured to the bottom Ila of the hner is the means for cooperating with the projections' to hold the liner in position. In the broader aspects of the invention, this means may be a ring, annulus or segments thereof ,of stiil', pliable, resilient material located around the bottom to provide a sti projecting flange or rim adapted to interengage with the projections I4. In the preferred form of the invention, however, a base I8 of still?, pliable, paper-like material is stamped out so as to be coextensive with and overlie the bottom of the liner and secured thereto to project beyond the edge thereof to form a flange or rim I8a to hold the liner tothe holder through cooperation with the projections thereon.
This base also reinforces the bottom of the liner and prevents` it from tearing through should it become softened due to the moisture of the material placed in the dish, or when a cutting implement is used to cut said material in the dish.
The liner and the base member-can beblanked out in the factory and secured together by suitable adhesives or cements and shipped ready for insertion into the holder. In the alternative,
- the liner and base member can be shipped separately and assembled by the user. When this method is contemplated, the bottom of the liner4 may be provided with dry adhesive or the like and the top of the base also provided with dry adhesive or the like. The linersand base members, when so prepared, can be separately stacked associate a liner and a basewlth the adhesive surfaces in engagement with one another and apply a pressure thereto whereupon the two will be secured together. A
In assembling a liner with a holder, the liner is inserted into the holder and the projecting rim I8a first engages the inclined upper surfaces I6 of the projections I 4. Pressure is applied to the liner and continued movement inward causes the rim to pass over these surfaces and be cammed and flexed thereby. As the rim passes over the lower edge of the projections, it snaps into the position shown in Fig. 2 and interlocks with the shoulders to hold the liner in proper position in the holder and against accidental removal therefrom.
I'he holder is provided with an aperture I9 in the bottom surface thereof and through which the fingers of the user or an implement can be inserted to engage the bottom surface of the reinforcing base member and apply pressure thereto in an outward direction which causes the base member to ex and the rim to release from its engagement with the shoulders, whereupon the liner snaps free of the holding means and may then be readily removed for disposal or replacement.
It has been found that when the liner and base are to be assembled by the user, the two can be readily centered by a novel process which comprises rst inserting the reinforcing base member into the holder with the adhesive side facing upwardly.
The thin paper liner is then'positioned in the holder, and, inasmuch as it conforms to the shape of the holder, will properly center itself.
.Pressure is then applied to the bottom of the fwithin the scope of this invention and portions accidental removal therefrom.
