A sheet metal lid has a rim portion removably secured and sealed to a container and the lid includes a vent button having a top wall portion surrounded by a side wall portion and an outwardly projecting flange portion. The flange portion of the button has a short arcuate score or shear line extending substantially into the sheet metal, and additional score lines extend into the flange portion at lesser depths to protect a coating on the inner surface of the lid. A resilient sealant material may be bonded to the inner surface of the vent button, and the opposing sheet metal portions of the score line form a small gap for releasing a vacuum or pressure from the container in response to a controlled downward pressure on the top wall portion of the vent button.

The present invention is directed to a child resistant double seam container lid including an adapter ring for securely affixing to the double seam top rim of conventional containers that will be difficult for children to open, yet readily openable by adults. More particularly, a two-piece, and three-piece child resistant double seam affixable container lid is provided having a first piece lid portion, a second piece adapter ring locking member second piece and optionally a third piece securing unit piece, with first and second rotational alignment indicators on the lid portion and adapter ring, and optional additional integral features such as a liquid measuring cup feature, a liquid tight lid feature, a threaded lid portion, a replaceable double seam container lid portion and a double seam container lid locking member adapter ring variously configured to be securely affixable to the double seam container rim.

A disposable, non-toxic, biodegradable, flexible cover fitting on beverage containers to protect from unwanted contamination or spillage is described. In one embodiment, the invention provides a cover for a drink container, the cover comprising: a flexible body having a substantially flat, circular shape; a bead disposed about a circumference of the flexible body; and an indicator visible on at least one surface of the body at which a puncture through the body may be made.

A bottle assembly is provided including a bottle having an end portion with 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 including 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 are arranged to allow air to enter the drinking vessel when the sealing member is in the unsealed position.

The invention provides a container lid (1) comprising: a closure panel (7) comprising an inside surface and an outside surface; a container fastening portion (9); and a liner (5) comprising one or more layers, connected to the inside surface of the closure panel, wherein the liner or at least a lowermost layer of the liner is detachable from the closure panel, characterized in that said container lid comprises a resilient portion (15) located between said closure panel and said fastening portion.

The Applicant's invention provides a lid for a food container including a cover, a dressing storage compartment, and a shutter attached to the cover or the dressing storage compartment for sealingly closing the dressing storage compartment. The shutter is configured to allow dispensing of the dressing contained in the dressing storage compartment when the dressing storage compartment is caused to move up relative to the cover, without the need of opening the lid. The Applicant's invention also provides a food container including the lid.

A cover structure is disclosed. When an annular sealing portion of a cover body is engaged with a container, a sealing section of the annular sealing portion abuts against an annular inner surface of the container, and then, a folding section of the annular sealing portion is folded to a sealing state, so that part of the folding section abuts against the annular outer surface of the container to form a dual leak-proof sealing structure. The folding section of the annular sealing portion is an annular elastic and full-peripheral tightening structure. Therefore, the sealing between the container and the cover may be strengthened for a good sealing effect, and preventing liquid in the container from being splashed on surrounding articles. When the folding section is in the unsealing state, the cover can be separated from the container, which is convenient to carry and use.

A closure system with a three-dimensional structure with an opening and a lid for plugging onto the three-dimensional structure in order to close the opening. The lid is bistably deformable between a first state, in which its end wall is curved in the plug-in direction, and a second state, in which the end wall is curved against the plug-in direction. An annular edge section of the lid has a greater outer circumference in the first bistable state than in the second bistable state and forms a clamping fixture of the lid to a wall region of the opening when the edge section is pressed inwards in the first state or outwards against the wall region in the second state. The three-dimensional structure transfers a force from the outside at specified locations that to a snapping process of the lid from one to the other bistable state.

The present invention is directed to a child resistant double seam container lid including an adapter ring for securely affixing to the double seam top rim of conventional containers that will be difficult for children to open, yet readily openable by adults. More particularly, a two-piece, and three-piece child resistant double seam affixable container lid is provided having a first piece lid portion, a second piece adapter ring locking member second piece and optionally a third piece securing unit piece, with first and second rotational alignment indicators on the lid portion and adapter ring, and optional additional integral features such as a liquid measuring cup feature, a liquid tight lid feature, a threaded lid portion, a replaceable double seam container lid portion and a double seam container lid locking member adapter ring variously configured to be securely affixable to the double seam container rim.

A hydration system that utilizes a disposable drink container and a leak-resistant cap. The cap can be screwed into the disposable drink container before use. The disposable drink container has a safety foil region with a foil disk having one or more output holes, which is covered with a liner. The user should remove the liner to uncover the output holes and reattach the cap before drinking the liquid in the container. The cap can have a spout section with a leak-resistant section to draw out the liquid. The leak-resistant section can have a curved lip that creates a narrow liquid opening, such that liquid is held in place (does not spill) by surface tension when the system is accidentally inverted or overturned. The cap can also have a sealing ring to create a liquid-tight seal between the cap and the drink container.
