Abstract

A heated air popcorn popper and related methods of popping popcorn in which unpopped kernels are retained in a heating zone and are prevented from being expelled before they have been exposed to a heated air stream for sufficient time to result in popping of the kernels. The popcorn popper can have a popping portion including a retention mechanism capable of moving in response to physical contact with popped kernels that experience a dramatic volumetric increase in size following popping. As the number of popped kernels within the popping portion increases, the level of the popped kernels rises until they physically contact the retention mechanism, whereby the retention mechanism is forced to transition from a covering disposition to an open disposition in which popped kernels are allowed to exit the heating zone.

First claim

The invention claimed is:

1. A popcorn popper, comprising:
a base assembly including a popping portion, the popping portion including a popping floor and a kernel retention mechanism, the popping floor having perforations to vent heated air into the popping portion to cook kernels, and the kernel retention mechanism having at least one lid member, the lid member hingedly attached to the popping portion proximate to an upper opening of the popping portion such that the lid member is rotatable between a covering disposition in which the upper opening is covered by the lid member and an open disposition in which at least a portion of the upper opening is uncovered by the lid member, the at least one lid member is adapted to transition from the covering disposition to the open disposition in response to contact with popped kernels within the popping portion, the at least one lid member being further adapted to permit popped kernels to be ejected from the popping portion at least partially by the heated air used to cook the kernels after the at least one lid member transitions from the covering disposition to the open disposition.

2. The popcorn popper of claim 1 , wherein the kernel retention mechanism includes a plurality of lid members, each lid member being individually hingedly attached to the upper opening, wherein each lid member is individually rotatable between the covering disposition and the open disposition.

3. The popcorn popper of claim 2 , wherein at least one of the plurality of lid members further comprises a limit stop member, the limit stop member interfacing with a popping wall to limit a travel amount of the corresponding lid member between the covering disposition and the open disposition.

4. The popcorn popper of claim 3 , wherein the travel amount is equal to or less than a 90 degree angle defined between an upper opening plane and a lid member plane.

5. The popcorn popper of claim 1 , wherein the at least one lid member includes a plurality of lid openings, said lid openings adapted to allow air flow through the lid member with the lid member in the covering disposition.

6. A method for increasing kernel popping in a popcorn popper:
filling a popping portion of a popcorn popper with unpopped kernels;
supplying heated air to the popping portion so as to cause the unpopped kernels to pop and thereby fill the popping portion with popped kernels; and
retaining the popped kernels within the popping portion with a lid assembly on an opening of the popping portion until the popped kernels fill the popping portion, thereby causing the lid assembly to transition from a covering disposition to an open disposition;
after the lid assembly transitions to an open disposition, expelling the popped kernels from the popping portion at least partially using heated air.

7. The method of claim 6 , wherein the lid portion comprises a plurality of lid members with each lid member being individually, rotatably attached to the popping portion, wherein the step of retaining the popped kernels, further comprises:
individually rotating each lid member between the covering disposition and the open disposition.

8. The method of claim 7 , wherein at one lid member includes a limit stop member, and wherein the step of individually rotating each lid, further comprises:
limiting a maximum rotation angle for at least one of the lid members though interaction of the limit stop member and the popping portion.

9. The method of claim 8 , further comprising:
limiting the maximum rotation angle to between 0 degrees and 90 degrees.

10. The method of claim 6 , wherein the lid assembly includes a plurality of lid openings and wherein the method further comprises:
exhausting heated air though the plurality of lid openings when the lid portion is in the covering disposition.

11. A popcorn popper, comprising:
a base assembly including a popping portion, a dish portion at least partially surrounding the popping portion, the popping portion including popping floor with perforations to vent heated air into the popping portion to cook kernels, and a retainer for holding unpopped kernels within the popping portion wherein the retainer transitions between an initial covering disposition and an open disposition in which popped kernels are released into the dish portion at least partially as the result of heated air flowing through the popping portion.

12. The popcorn popper of claim 11 , wherein the retainer for holding unpopped kernels rotatably transitions between the initial covering disposition and the open disposition.

13. The popcorn popper of claim 12 , wherein the retainer for holding unpopped kernels comprises a lid assembly that is hingedly attached proximate an upper opening of the popping portion.

14. The popcorn popper of claim 13 , wherein the lid assembly comprises a plurality of lid members, each lid member being individually hingedly attached proximate the upper opening.

15. The popcorn popper of claim 14 , wherein at least one of the lid members includes a limit stop member, the limit stop member interfacing with the popping portion to restrict a maximum rotation angle of the at least one lid member.

16. The popcorn popper of claim 15 , wherein the maximum rotation angle is limited from about 0 degrees to about 90 degrees.
