Abstract
A closure system can be attached to existing paint pails, cans, and other, similar metallic containers. It includes a crimped insert ring attaching to the container and a primary lid, preferably having tamper-evident features. A secondary lid is seated on and seals to the primary lid, with the secondary lid possibly being made partially or completely from plastics, thereby facilitating its ability to reseal the paint container by way of a plug seal. The insert, primary lid, and secondary lid may have one or more annular grooves or ridges to facilitate their attachment to one another.
Claims11
A tamper-evident closure system for cylindrical paint containers, the system comprising:
- an annular ring having an outer peripheral edge configured for attachment by way of crimping, an inner peripheral edge, and a mid-section including an engagement groove and radial ledge;
- a primary lid seated on a top facing of the annular ring, the primary lid having a central portion with a tamper evident panel defined by a thinned groove formed in the central portion, a peripheral edge that couples to the outer peripheral edge of the annular ring, and middle portion positioned between the central portion and the peripheral edge of the primary lid and including a ridge and a groove configured to be seated within the groove of the annular ring;
- a secondary lid seated on a top facing of the primary lid, the secondary lid having an attachment feature on its peripheral edge and a solid panel that covers and seals the central portion of the primary lid;
- and
- wherein, prior to removal of the tamper evident panel, both the primary and secondary lid seal create a seal over an opening in the annular ring and wherein an axial elevation of the tamper evident panel is:
- i) above that of both the thinned groove and a lower extremity of the groove in the primary lid, and ii) below that of the mid-section of the annular ring.
