A new bottle cap comprising a cap body and at least one air-return valve having a drinking port and an air-return port which is correspondingly disposed to the air-return valve are disposed on the cap body; an anti-leakage valve is disposed in the drinking port; the place where the air-return port is located extends inwardly to form a convex portion in the cap body; one end of the air-return valve is connected to the convex portion in a matching way, and the other end of the air-return valve is a closed port structure; one end of the air-return valve is designed to be a closed port structure, which can effectively prevent the air in the cap body from outflowing through the air-return valve.

A plastic closure embodying the principles of the present invention comprises a closure cap having a top wall portion, and an annular skirt portion depending from the top wall portion. The skirt portion includes an internal thread formation for threaded engagement with the external thread formation of an associated container. In order to facilitate high-speed application, and minimize the use of polymeric material, the closure is configured to exhibit a variation in retention force which decreases in a direction away from the top wall portion of the closure cap.

The present disclosure relates to a lid and a method of using a lid. The lid includes a body having a top surface, a bottom surface, and a perimeter. The lid also includes a sealing member carried by the perimeter of the body. The sealing member is configured to move between a first position and a second position. The method of using the lid includes the step of positioning the lid with the sealing member in a second position above an open end of a container. The method further includes the step of securing the lid and the container together by moving the sealing member from the second position to a first position to cause engagement of the sealing member with the container thereby forming a removable attachment and a substantial seal between the lid and the container.

A packaging assembly includes a box storage compartment that forms a sealed unit package capable of containing a number of peroxyacetic acid solution-storing containers. The package has a number of reinforced compartmented spaces to hold the containers during transport and can optionally have an absorbing agent material in the spaces and/or base portion of the package. The packaging assembly allows a predetermined amount of peroxyacetic acid solution to be safely transported to an area where the solution can be easily and safely used and without the need for special equipment or handling procedures.

A portable water purifying bottle comprises: an upper cover, having a water output port; a filter core component, disposed inside the upper cover, and located below the water output port; and a plastic cup sleeve, sleeved into a lower portion of the upper cover. The portable water purifying bottle is simple in design, the plastic cup sleeve made of silicone for storing water is retractable for easy carrying, thus fulfilling the needs of outdoor user. Further, the portable water purifying bottle is able to provide water output at fast speed to save time, while its appearance is compact and pleasing, hereby having a good prospect in the market.

A one-way valve integrated into a lamination of the kind used as a membrane seal for coffee containers and the like. The valve comprises a top layer, a substrate and a fluid polyol film. The top layer and the substrate are adhered together by an adhesive disposed between the top layer and the substrate. The adhesive defines a boundary of a valve chamber in which the top layer and the substrate are not permanently adhered to each other. The film enhances the adhesiveness of the top layer to the substrate in the area of the valve chamber so that gas inside the container does not escape until the internal pressure reaches a minimum value.
