Abstract

A container ( 10 ) for holding a bundt cake ( 12 ), which avoids an unsightly accumulation of sugar frosting around the central hole in the cake, and which provides strength for stacking containers with cakes therein on top of one another. The container includes a base ( 14 ) with a cake-supporting surface ( 30 ) and a central upward projection ( 32 ) for insertion into the central cake hole, and a cover ( 16 ) with a cover top ( 20 ) and with side walls ( 22 ) that have bottoms ( 24 ) that latch to the base. The central upward projection has a plurality of largely vertically extending grooves ( 40 ) that allow hot frosting to flow down to a recess ( 44 ) lying below the cake-supporting surface. The middle of the cover forms a downwardly-extending post ( 62 ) that engages the top of the center projection on the base, to support the cover, especially when containers holding cakes are stacked. The cover periphery has a raised rim portion ( 80 ) that fits into a corresponding circular recess space ( 104 ) in the lower surface of the base to further help in stacking.

Claims (11)

1. A container and a cake that has a central vertical hole, comprising:

a base which comprises a piece of plastic that has been formed with a cake-supporting surface with said cake lying thereon, said base having a rim portion and a central upward projection that projects upward into the hole in the cake, said projection having a top surface;

a cover which comprises a piece of plastic that has been formed with a primarily horizontal cover top wall and with cover side walls that have a bottom that holds to said rim portion;

said cover top wall is formed with a post part that is narrower than said upward projection and that projects a plurality of centimeters downward to lie against said top surface of said projection at least when the cover top wall is pushed down.

2. The container described in claim 1 wherein:

said post part has a diameter and has a vertical height that is greater than said diameter.

3. A container for holding a cake that has a central vertical hole, comprising:

a base which comprises a piece of plastic that has been formed with a cake-supporting surface, a rim portion, and a central upward projection for projecting into the hole in the cake, said projection having a top surface;

a cover which comprises a piece of plastic that has been formed with a primarily horizontal cover top wall and with cover side walls that have a bottom that holds to said rim portion;

said cover top wall is formed with a post part that projects downward to lie against said top surface of said projection at least when the cover top wall is pushed down;

said projection has a lower portion extending along most of the height of the projection and which is tapered so its sides extend at a first taper angle from the vertical, and said projection has an upper part of a height of at least one centimeter which is tapered so its sides extend at a second taper angle to the vertical that is at least twice said first taper angle.
