A thread joining mechanism which possesses and for annular engaging external surface and/or internal surface, preferably for the containers with annular opening, comprising: at least an external thread line, including upper end and lower end which outspread along annular engaging external surface and/or internal surface, at least a convex fixed area and locking piece, preferably be processed as configuration by a part of said upper end and lower end which close to said external thread line, or preference is given to the convex part that integrates with said annular engaging external surface and/or internal surface, said fixed area and locking piece are set to that said annular engaging external surface and/or internal surface, and upper end and/or lower end of corresponding said thread line are separated by preset spacing, and outspread along the same direction with said thread line.

A stackable container lid includes a top surface defining a flat surface plane without an upward protrusion, at least one recess in the top surface, a bottom surface including a rib structure adjacent a perimeter, and at least one nest segment integrated with the rib structure and protruding from the rib structure. The container lid is readily stackable with other container lids and is suited for handling with automation equipment.

A lid for outfitting a container is provided. The lid includes a cover shell defining a first cavity, a first lid rim defining an opening, and a hinge member constructed to pivotally interconnect the first lid rim with the cover shell. The cover shell releasably lockable to the first lid rim.

A cap for a container having a pair of side walls each with an inner wall surface. Each inner wall surface having a minimum of two pairs of ribs distributed thereon for retention of a liner. Each of the a minimum of two pairs of ribs has a concave arc with a concave radius of curvature forming a curved portion of the inner wall, and a convex arc. Each of the a minimum if two pairs of ribs has a different overall configuration that facilitates removal, and securing onto, of the cap from/to the container without damage of the ribs and the retention of the liner in the cap.

A container apparatus having at least one containment member is disclosed that may include a bottom and at least one sidewall, an interior and an open end. The container may also include a flange that extends around a free end of the at least one side wall, and a plurality of wall members (or castellations) connected to/formed with/that extend from the flange. The plurality of wall members may be separated by ventilation apertures, with the plurality of wall members and the ventilation apertures extending around the perimeter of the free end. A sealing material, such as a removable film, may extend over the open end to enclose the containment member.

An apparatus and method for manufacturing a container with a closure-release mechanism. The process in particular relates to thermoforming a plastic sheet to form a container with a clam shell locking system in order to facilitate a secure closure and easy opening packaging container. The clam shell locking arrangement comprises a post which is secured in an aperture when the container is in closed state. The post is a projection or protrusion in a vertical or nearly vertical sidewall of the cover of the thermoformed package and fits securely into the aperture, which is a cut-out made in the outer, and optionally also the inner, wall segments of the vertical or nearly vertical surfaces of the base section of the thermoplastic containers.

A bottle assembly is provided. The bottle assembly comprises a bottle having an end portion including a first detent formation, and a collar having a second complementary detent formation. The collar is arranged to snap fit to the end portion by engagement of the detent formations by application of force only in a direction towards the bottle. In addition, a valve assembly for use with a drinking vessel is provided. The valve assembly comprises a base member and a sealing member. The sealing member is moveable, dependent on a pressure difference across it, between a sealed position, wherein the sealing member is sealed against the base member, and an unsealed position, wherein the sealing member is unsealed from the base member. One or more channels are formed between the base member and the sealing member and extend to a periphery of the sealing member. The one or more channels are arranged to allow air to enter the drinking vessel from the periphery of the sealing member when the sealing member is in the unsealed position.

A food package for sliced food products to be maintained with a fluffed appearance, the package including a rigid base member forming a compartment for receiving the food product and a rigid lid sealed to the compartment. Advantageously, the base member includes a bottom wall and side wall portions that are configured to engage the food product to hold the slices in a fluffed arrangement thereof. Preferably, one or more tapered side wall portions hold the food product upwardly toward the lid and inwardly toward a center of the package. In preferred embodiments, the base member and lid provide a rigid-rigid construction of the food package. In preferred embodiments, the food package is also configured to stand-up in a vertical display orientation and does not require the food product be contained within a sealed pouch within the compartment.
