A tamper-resistant container defining an opening extending into a canister chamber. A lid is sized and configured to engage the canister rim for closure of the opening. The container is configured to be of a maximum height H less than or equal to 85% of a maximum width W.

The hybrid plug is a single component replacement for three components, the paint plug, conventional plug and capseal in a drum closure. It is formed from a single sheet of metal and has a plug portion and a capseal portion which vary in thickness. The plug portion has a collar and an externally threaded wall with a plug gasket disposed on a plug gasket seat. The capseal portion is provided with ears and scoring to enable separation from the plug portion and with a lining on the inner wall of the capseal portion to safeguard against plug gasket failure. The capseal portion may be recessed at intervals to form dimples which hold the hybrid plug in place in an automated insertion process. The hybrid plug provides a passage for air and gases during paint curing and leak testing without necessitating removal.

A container includes a container portion and a lid portion. The container portion presents a tab rim and internal threads. The lid portion presents a plurality of flexible removable tabs disposed around its outer periphery. The tabs are adapted to engage with and interlock with the container tab rim when the lid portion is pressed down on the container. The lid portion also has helical threads that are arranged to engage the helical threads of the container portion. At least one of the set of helical threads of the container portion or the set of helical threads of the lid portion are able to flex when the lid portion is pressed down upon the container portion. A closed container may be adapted for repeated use by removing the tabs and using the threaded lid portion to open and close the container.

The present invention relates generally to a container that may be sealed and reclosed with a threaded closure. More specifically, the present invention relates to methods of manufacturing a metallic container having an opening with inwardly facing threads. The threads are formed on the metallic container by pressing a neck portion of the metallic container against closure threads of a threaded closure which is inserted at least partially into the opening. The container threads may optionally be formed while the threaded closure is in tension. In this manner, after the container threads are formed, the closure threads can apply a force to the container threads such that the threaded closure is in tension. The container opening may be selectively sealed and reclosed with the threaded closure which releasably engages the container threads. Novel apparatus and methods of sealing metallic containers and forming threads on the metallic containers are also disclosed.

A container is provided with a lid having a removable thermometer for measuring the temperature of liquids in the container. A gasket is provided to secure the thermometer to the lid and maintain a hermetic seal between the thermometer and the gasket and between the gasket and the lid. The gasket is resilient to maintain the hermetic seal when the thermometer is subjected to torque or other stresses such as may occur when the lid is attached or detached from the container.
