Abstract
A container, such as a roll-out cart, includes a body portion and a lid. The body portion includes an outer wall extending upward from a base wall to a mouth of the body portion. The lid is secured to the body portion and pivotable between a closed position over the mouth and an open position. The lid includes an upper lid portion and a lower lid portion. The upper lid portion extends downward to an outer lip. The lower lid portion extends downward to an inner lip. The inner lip is inward of the outer wall of the body portion when the lid is in the closed position. The outer lip is outward of the outer wall of the body when the lid is in the closed position.
Claims26
A method of making a container lid including:
- a) thermoforming an upper lid portion including thermoforming a first polymer sheet as the upper lid portion and forming a plurality of rearward projections for hingeably securing to a handle spaced rearwardly of a container;
- b) thermoforming a lower lid portion;
- c) placing an RFID tag between the upper lid portion and the lower lid portion;
- and
- d) securing the upper lid portion and the lower lid portion together.
A method of making a container lid including:
- a) thermoforming an upper lid portion including forming an upper lip projecting downward from a periphery of an upper panel portion of the upper lid portion;
- b) thermoforming a lower lid portion including forming a lower lip projecting downward from a periphery of a lower panel portion of the lower lid portion and forming a platform higher than the periphery of the lower panel portion of the lower lid portion:
- c) placing an RFID tag between the upper lid portion and the lower lid portion, wherein the platform is spaced below the upper lid portion, and wherein the RFID tag is positioned on the platform;
- and
- d) securing the upper lid portion and the lower lid portion together.
A method of making a container lid including:
- a) thermoforming a first polymer sheet into an upper lid portion having an upper lip projecting downward from a periphery of the upper lid portion;
- b) thermoforming a second polymer sheet into a lower lid portion, including forming in the second polymer sheet a lower lip and a double-walled hollow inner lip spaced inward of the lower lip, wherein the lower lip projects downward from a periphery of a lower panel portion of the lower lid portion, wherein the double-walled hollow inner lip extends about at least a front edge and opposed side edges of the lower lid portion;
- and
- c) securing the upper lid portion and the lower lid portion together.
A method of making a container lid including:
- a) forming an upper lid portion including forming an upper lip projecting downward from a periphery of the upper lid portion;
- b) forming a lower lid portion having a lower lip projecting downward at a periphery of a lower panel portion of the lower lid portion, including forming a double-walled hollow inner lip spaced inward of the lower lip, wherein the double-walled hollow inner lip extends downward further than the lower lip;
- and
- c) joining the upper lid portion to the lower lid portion via twin sheet thermoforming, adhesive, or welding.
A method of making a container lid including:
- a) thermoforming a first polymer sheet into an upper lid portion having an upper lip projecting downward from a periphery of the upper lid portion;
- wherein step a) includes forming a plurality of rearward projections for hingeably securing to a handle spaced rearwardly of a container;
- b) thermoforming a second polymer sheet into a lower lid portion, including forming in the second polymer sheet a lower lip and a double-walled hollow inner lip spaced inward of the lower lip, wherein the double-walled hollow inner lip extends about at least a front edge and opposed side edges of the lower lid portion;
- and
- c) securing the upper lid portion and the lower lid portion together.
A method of making a container lid including:
- a) thermoforming an upper lid portion;
- b) thermoforming a lower lid portion, including forming a lower lip projecting downward from a periphery of the lower lid portion and forming a double-walled hollow inner lip spaced inward of the lower lip and extending downward further than the lower lip;
- c) placing an RFID tag between the upper lid portion and the lower lid portion;
- and
- d) securing the upper lid portion and the lower lid portion together.
