Abstract

A container having a base and a lid which are capable of being releasably coupled at their outer circumferences. The base and lid are constructed of a lightweight, semi-rigid material. The base is deformable, within limits, in response to the pressure applied thereon but will return to its original shape when the deforming force is removed. Inclined, stepped sides extend from the bottom of the base and form a plateau to accommodate and support a pie tin and to hold the edges of the container extending past the rim of the pie tin away from the pie crust, filling and topping. When pressure is applied to depress opposite sides of the base at the top the base deforms to squeeze against the slanted sides of a pie tin therein, thereby raising the pie tin above the plateau such that a users fingers can be moved under the edge of the pie plate to lift it from the base.

STANFORD W. BIRD EQMM ATTORNEY PIE CONTAINER BRIEF DESCRIPTION OF THE INVENTION 1. Field of the Invention This invention relates to containers for the housing, storage and transportation of pies and the like.

2. Prior Art The need for packages in which pies prepared for commercial sale can be stored, transported and displayed has long been recognized. In the past, cardboard boxes have been used for such packaging and many times plastic window inserts have been provided in the boxes so that at least a portion of a pie inside can be viewed without opening of the box. The cardboard boxes are inexpensive and do provide some protection for the product inside during storage and transport, but they cannot be sealed so as to restrict air passage and they lack structural strength so that filled boxes cannot be stacked one on top of another to the extent desired and a box and its contents are frequently crushed. Frequently, it is difficult to open the cardboard box and to remove a pie therein without sticking a finger in the pie or without damaging the pie edges. Also, in the event the pie tin and contents slides to one side of such a carton, the peripheral crust and pie topping are apt to be damaged.

The cardboard boxes, while providing a measure of protection for the product therein are seldom very attractive and even if provided with plastic window inserts do not attractively exhibit pies placed therein.

The present invention provides a container which is specifically constructed to house and display a pie type food product and that overcomes the deficiencies inherent in the package previously used.

SUMMARY OF THE INVENTION Principal objects of the present invention are to provide a low-cost container in which a pie-like food product can be stored and transported and from which the product can be easily removed.

Another object is to provide a container having base and lid sections that can be releasably connected such that the connected sections are sufficiently sealed that the passage of air into the container interior is restricted.

Still other objects are to provide a container that will attractively display a pie-type'food product and that has sufficient structural strength to allow for safe stacking of the filled containers.

Principal features of the present invention include a plastic base and a plastic lid (preferably transparent) that can be releasably connected at their circumferences is such a manner as to effectively reduce the admission of air into the container interior.

The base has a bottom and a lower section wherein a slanted side wall extends upwardly and outwardly therefrom with an intermediate step therein forming a plateau spaced above the bottom of the container. A pie tin, whether of aluminum foil or other material fits snugly within the slanted side wall and the outermost lip of the tin rests on the plateau and cannot slide with respect thereto, even if the container is tipped somewhat. The side wall, above the plateau, is spaced sufficiently far from the outermost periphery of the pie tin that it does not engage a pie crust on the lip of the tin and extends sufficiently upwardly that the lid section placed thereon does not engage any filler or topping on the pie. The base section is constructed of a deformable plastic material so that when opposite sides of the wall of the section are depressed, portions of the wall between the depressed sides pull inward to squeeze the inclined surface of a pie tin contained therein. This pushes the pie tin upwards until the user can insert his fingers under the outermost flange of the tin to lift it from the base. When the depressing pressure'is removed from the side wall, the base returns to its original assigned shape. Y

The lid section is constructed of a lightweight, semirigid plastic material, such as a plastic, in which various designs, lettering, or symbols may be molded, and is preferably transparent, so that the container contents may be viewed.

Additional objects and features of the invention will become apparent from the following detailed description and drawings, disclosing what is presently contemplated as being the best modes of the invention.

DETAILED DESCRIPTION Referring now to the drawings:

In the illustrated preferred embodiment the container, shown generally at 10, is round and consists of a lid section 11 and a base section 12. The lid section 11 is shown as having a depression 13 formed in the center of a top surface 13a. The ridge forming the depression adds strength to the lid and the depression is shaped to receive the bottom of the base of a similar container stacked thereon. The depression thus helps to stabilize stacks of the container.

Lettering or writing or a design may be formed in the lid to advertise the source of the food product housed therein or for any other desired reason.

The base section 12 has a bottom 14 and a side wall 15 which is inclined upwardly and outwardly from the bottom to accommodate the inclined sides of a pie tin 16, as shown best in FIG. 4. The wall 15 is stepped to form a plateau 17 intermediate the height of wall 15 and above the bottom 14. The outermost flange or lip 16a of pie tin 16 rests on plateau 17 and the inclined wall 16b of the pie tin engages and rests on the wall 15.

A lip 18, which extends around the outer circumference of the base section 12, is adapted to fit into a groove 19 which is formed in the outermost flange20 of a depending circumferential wall 21 of the lid sec- As shown in FIGS 5-7, it its" a'siniple matter tore- I move apie tin (and apie therein, not shown) from the container 10. The lid section l] is removed, ashas been heretofore described, and the user pushes down at the top on opposite sides of the sidewall 15.The side wall 15, between the points at which the downward pressure is applied squeeae against the inclined wall 16b of the pie tin 16. This forces the pie tin up until the usercan position his fingers beneath theoutermost I between the flange 16a the side wall and plateau 17 during transport, storage and display and can be readily removed from the container without the user having to insert hishands into a container and thereforwithout damage to the product on the pie plate; Theportion of the side wall abovethe plateau is spaced from the outermost lip of distance to clear any toppingputon a pie.
