Abstract
A plastic container having a container body and a permanently attached container lid is provided. The container lid is attached to the container body by a living hinge such that the entire plastic container is a one-piece construction. The container lid is pre-curved such that in an open state the container lid is curved. However, when the container lid mates with the container body in a closed state, at least a portion of the container lid that was previously curved becomes substantially planar such that portions of the lid remain biased into the container body. The container can also incorporate a carrying feature for receiving and positioning articles therein, as well as a sealing chamfer for reducing the likelihood of the ingress of foreign matter into an interior cavity of the container.
Claims13
A plastic container comprising:
- a generally cup-shaped container body, having a bottom and a sidewall depending upwardly from the bottom, the bottom and the sidewall defining a storage area, the container body including a flange formed on the sidewall, the flange extending radially outward from the sidewall;
- a lid coupled to the container body by a living hinge, the lid adapted to rotate about the living hinge between an open and a closed position, the lid including a sealing flange and a skirt each depending downwardly from a bottom surface of the lid, wherein a receiving channel is formed between the sealing flange and the skirt;
- and
- a carrying feature formed in the bottom, the carrying feature interrupting the bottom such that the bottom is non-planar;
- wherein the carrying feature includes a skirt depending upwardly from the bottom of the container, the skirt depending upwardly within an internal cavity of the container body to cordon off a carrying region;
- and
- wherein the skirt is supported by a plurality of regularly spaced support ribs extending from the sidewall to an outer surface of the skirt.
A plastic container comprising:
- a generally cup-shaped container body, having a bottom and a sidewall depending upwardly from the bottom, the bottom and the sidewall defining a storage area, the container body including a flange formed on the sidewall, the flange extending radially outward from the sidewall;
- a lid coupled to the container body by a living hinge, the lid adapted to rotate about the living hinge between an open and a closed position, the lid including a sealing flange and a skirt each depending downwardly from a bottom surface of the lid, wherein a receiving channel is formed between the sealing flange and the skirt;
- and
- a carrying feature formed in the bottom, the carrying feature interrupting the bottom such that the bottom is non-planar;
- wherein the carrying feature comprises a bottom surface facing the storage area the surface having a cross section with alternating curved concave and convex portions, wherein each concave portion has a first radius of curvature and wherein each convex portion has a second radius of curvature, the first radius of curvature greater than the second radius of curvature.
A plastic container, comprising:
- a lid having a sealing flange depending downwardly from an interior surface of the lid;
- a container body having a bottom and a sidewall with a sealing flange formed at an end of the sidewall, wherein the lid and container body are connected by a living hinge, the sidewall terminating in a living hinge;
- a sealing chamfer formed on an interior side of the sidewall of the container body at the distal end, the sealing chamfer configured to sealingly engage the sealing flange when the container is in a closed position;
- and
- a carrying feature formed in the bottom, the carrying feature interrupting the bottom such that the bottom is non-planar;
- wherein the carrying feature includes a skirt depending upwardly from the bottom of the container, the skirt depending upwardly within an internal cavity of the container body to cordon off a carrying region;
- and
- wherein the skirt is supported by a plurality of regularly spaced support ribs ee tending the sidewall to an outer surface of the skirt.
