The lid is made of multilayer material comprising two layers of PP framing an EVOH barrier layer, said lid having on its lower face (21) a circular groove (5) housing the sealing gasket, a central portion (23) of said lid forming a convex dome (23a) raised outwards before vacuuming and capable of becoming concave (23b) during vacuuming, while a circular groove (24) surrounding the convex dome (23a) is provided at the level of the upper face (22) of the lid, the latter also being provided, on its entire perimeter, with a closing rim (6) having snap-on means (61, 62).

The utility model relates to a sealing device of an infusion specimen bottle, which belongs to the technical field of specimen bottles and comprises a specimen bottle, a sealing component and an inflating component, the sealing component comprises a bottle plug and a plurality of groups of sealing rings, the sealing rings are uniformly arranged on the surface of the bottle plug, the bottle plug is plugged at a bottle opening, the sealing rings are used for sealing the specimen bottle, and the inflating component is used for inflating the inflating component. A sealing ring is arranged in the bottle plug, an air bag is arranged between the sealing rings, the air inflation assembly comprises a hand-pinched air inflation ball and an air inflation pipe, the hand-pinched air inflation ball inflates the air bag through the air inflation pipe, a gap between the bottle plug and the bottle opening of the specimen bottle can be filled after the air bag is filled with air, and the situation that the sealing effect of the specimen bottle is affected due to volatilization of the air in the specimen bottle is avoided.

The present disclosure relates to the field of bottle stopper devices, and in particular, to a quick opening and closing container stopper, which includes a fixed shell and a movable stopper body. The fixed shell is provided with a dodging opening. The movable stopper body is provided with a limiting plate. An elastic sealing sleeve abuts against and between the limiting plate and the fixed shell. A knob is rotatably connected to the movable stopper body. The knob includes a side lug. When the container stopper is in a locked state, the side lug extends beyond a contour range of the dodging opening, and the fixed shell and the limiting plate are close to each other and drive the elastic sealing sleeve to bulge outward. When the container stopper is in an unlocked state, the side lug is accommodated in the dodging opening.

A tube set seal assembly including: a body configured for insertion into an opening of a container, a plurality of passages extending through the body, and an inflatable annular seal provided on the body. Wherein the body comprises an inflation channel in communication with the seal for supply of gas to the seal to cause the seal to inflate.

The application discloses a container plug capable of being quickly assembled and disassembled, which comprises a hollow handle, a plug body and an elastic sealing sleeve, the plug body comprises a positioning pin block and a spring pressing pin, the spring pressing pin is in abutment or separation with the positioning pin block in the process of moving away from or close to the positioning pin block; the hollow handle comprises a limiting boss, at least one guide slide rail is arranged on the limiting boss, and an elastic limiting piece is arranged on the first preset position of the limiting boss; the plug body is arranged in the elastic sealing sleeve and the hollow handle along the guide slide rail, the elastic limiting piece and the spring pressing pin are in abutment in the process of relative movement, the guide slide rail is in abutment with the positioning pin block and moves oppositely, and the two ends of the elastic sealing sleeve are connected with the hollow handle and the plug body respectively; the container plug capable of being quickly assembled and disassembled is characterized in that the elastic limiting piece presses down the spring pressing pin, the guide slide rail is pressed against the positioning pin block and moves oppositely, the plug body is arranged in the hollow handle, the assembly of the container plug is completed, and a certain assembly sequence is not needed.

Various systems for the containment or delivery of a product are provided. The systems allow for the storage of products at low temperatures and include a container closure inserted into a container (10). The container closure may have an elastomeric body (12) and include a material (14) having a negative coefficient of thermal expansion. In other systems, the material having a negative coefficient of thermal expansion may be inserted between the elastomeric container closure and a seal. Other systems may include an insert at least partially embedded within the elastomeric body of a container closure, an actuator having a distal end movably attached to the insert, and a resilient element between the distal end of the actuator and the insert, wherein the resilient material expands radially upon displacing the distal end of the actuator toward the insert.

The invention relates to a container closure device (for liquids) comprising: - a essentially frustomeric closure body made of an elastomeric material, - a hollow tube mounted in the closure body, and - an inflatable element fixed to one end of the hollow tube. Figure for the abstract: Figure 2
