Abstract
An improved stackable lid design for placement onto a container by automated processing machinery is disclosed. The design includes an alignment notch extending into a rim portion of the lid. The notch serves to keep individual lids in a stack of such lids in proper rotational alignment. The notch also enables a user to properly orient a stack of such lids within the processing machinery. The notch can be sized to receive an end user's finger for effecting removal of the lid from the container.
Claims3
A stackable lid for placement onto a container by automated processing machinery, the container having a flat peripheral ledge-like rim, the lid comprising:
- an upper cover portion;
- a rim portion continuous with the cover portion including a sidewall portion extending downward from the cover portion, a ledge portion for engaging said container rim, and a skirt portion adapted to extend downwardly around said container rim;
- a plurality of inwardly extending stacking projections formed in said sidewall portion;
- a plurality of locking projections on said skirt adapted to engaged beneath said container rim;
- and
- an alignment notch formed in said sidewall portion positioned directly above one of the locking projections, the alignment notch providing mechanical alignment means for rotationally aligning individual lids within a stack of such lids, the alignment notch providing visual means for enabling a user easily to detect the rotational orientation of a stack of such lids for a user's proper placement of a stack of the lids into a lid infeed portion of the automated processing machinery for preventing the processing machinery from becoming jammed due to misaligned lids.
A stackable lid for placement onto a container by automated processing machinery, the container having a flat peripheral ledge-like rim, the lid comprising:
- an upper cover portion;
- a rim portion continuous with the cover portion including a sidewall portion extending downward from the cover portion, a ledge portion for engaging said container rim, and a skirt portion adapted to extend downwardly around said container rim;
- a plurality of inwardly extending stacking projections formed in said sidewall portion;
- a plurality of locking projections on said skirt adapted to engage beneath said container rim, said plurality of locking projections being at least three in number, the first two of said at least three locking projections being positioned in one of the halves of the lid, the third of said at least three locking projections being centrally placed in the second half of the lid;
- and
- an alignment notch formed in said sidewall portion and positioned above the third locking projection, the alignment notch being sized to receive a digit of a human hand for effecting removal of the lid from the container, the alignment notch providing mechanical alignment means for rotationally aligning individual lids within a stack of such lids, and the alignment notch providing visual means for enabling a user easily to detect the rotational orientation of a stack of such lids for a user's proper placement of the stack into a lid infeed portion of the automated processing machinery for preventing the processing machinery from becoming jammed due to misaligned lids.
