A package for a medical device such as an intermittent catheter has a case with open and closed ends. A hinge connects a cap to the case to permit movement of the cap between open and closed positions. A seal connected to one of the cap and case is engageable with the other to maintain a sterile environment inside the package. The seal can be repeatedly made and broken whenever the user closes or opens the cap. The case includes a pair of slots at the open end. A pair of latches is formed in the cap. The latches fit into the slots to prevent lateral forces from distorting the cap when the cap is closed. A first use indication label spans a depression in the outer contour of a closed cap and case, assuring visual confirmation of breach of the label upon first opening of the cap.

Container (1) for foodstuffs comprising a main body (2) having a bottom wall (2a) and a perimeter side wall (2c) connected to the bottom wall (2a) so as to define a containment volume for foodstuffs. The perimeter side wall (2b) being provided with an edge portion (2c) distal from the bottom wall (2a).

The container (1) comprises a lid (3) comprising a central portion (3a) and engagement tabs (3b) extending from a perimeter portion (3c) of the central portion (3a) and configured to hook or to be hooked to the edge portion (2c) of the main body (2) so as to define a configuration for engaging the lid (3) with the main body (2). The central portion (3a) can be pressed by a user so as to obtain a movement of the engagement tabs (3b) away from the edge portion (2c), defining a configuration for disengaging the lid (3) from the main body (2).

An insulated container having a canister can be sealed by a lid structure. The lid structure can be a multi-part insulated lid. The lid can include a vent configured to vent air from inside the canister. In addition, the container may be part of a container kit or container system where one or more inner containers, are nested and secured within the insulated container.

This disclosure provides a box lid and an airtight box and belongs to the technical field of food preservation boxes. The box lid comprises: a lid body; and a sealing ring connected to the lid body, the sealing ring comprising an inclined portion inclined inwards, wherein the inclined portion can produce elastic deformation and is deformable to a sealing state. The beneficial effects of this disclosure are as follows: The specially designed sealing ring allows the airtight box to maintain an airtight effect when the interior is in a positive pressure environment, so the airtight box does not need air release after being sealed. When the box lid reaches the sealing position from the contact position, the air pressure in the box increases to assist the inclined portion of the sealing ring to achieve sealing.

Disclosed are a container cover and a vacuum preservation container. The container cover comprises a cover body and an air extraction assembly, wherein a first through hole is provided in the cover body, the air extraction assembly comprises an outer cover and an inner cover, the inner cover is arranged on an upper end of the first through hole in a sealing manner, a second through hole and a third through hole are provided in the inner cover, the second through hole is in communication with the first through hole, a first one-way valve is arranged in the second through hole, and a second one-way valve is arranged in the third through hole.

A storage tube assembly, with a cap having a top surface and a sealing member connected to the top surface, the sealing member has a generally cylindrical upper wall and a generally cylindrical lower wall, the sealing member also has a recessed portion between the upper wall and lower wall and a flange cut into the lower wall; a sealing ring, the sealing ring is sized to cooperate with and be received in the recessed portion of the sealing member of the cap; and a tube, the tube has a generally circular inner wall with a cut therein, the cut in the inner wall is positioned to receive the sealing ring when the sealing ring is positioned within the recessed portion of the cap and the cap is placed into an open end of the tube.

A storage container is disclosed, which includes: a container body; a folding line enabling folding and unfolding; a cover comprising a first and a second cover provided on the left and right sides of the folding line; a rotary pressing member rotatably provided on or near the folding line; and an elastic element coupled to the outer edge or inner side of the cover, wherein the cover can be inserted into the container body while folded, the cover is unfolded by a rotation of the rotary pressing member in one direction, the rotary pressing member is coupled to the cover so that the elastic element comes tightly contacts the inner wall surface of the container body and the cover maintains an unfolded state, and the cover is folded by a rotation of the rotary pressing member in the other direction so as to be separable from the container body.

A method for improving performance of a cup lid and a cup lid manufactured by the method are disclosed. The method includes: manufacturing a TPU handle with mounting holes, a stainless steel outer cover, a stainless steel top plate, a PP plastic inner ring with mounting snap positions, a PP plastic main body cover, a PP plastic honeycomb, a stainless steel vacuum piece, a silicone ring, and a sealing ring; setting connecting positions on the PP plastic main body cover, using bridge connectors to guide through the mounting snap positions, the connecting positions and the mounting holes; pressing the TPU handle, the stainless steel outer cover and the PP plastic inner ring against the PP plastic main body cover using the bridge connectors, so that a middle part of the bridge connector is restricted by the connecting position and the mounting snap position to limit the position of the ring.

A moisture tight container (100, 300) includes a container body (101, 301) and a lid (101, 120, 320) preferably linked to the body (101, 301) by a hinge (140, 340). The body (101, 301) and lid (101, 120, 320) include at least a first seal (462) and a second seal (464) in series to provide a moisture tight seal (460) between the body (101, 301) and the lid (101, 120, 320). The first seal (462) includes mating of thermoplastic-to-thermoplastic sealing surfaces of the body (101, 301) and lid (101, 120, 320) respectively. The second seal (464) includes mating of thermoplastic-to-elastomeric sealing surfaces of the body (101, 301) and lid (101, 120, 320), respectively, or of the lid (101, 120, 320) and body (101, 301), respectively.

It is desired to make an improved lid suitable for pails, overcoming the problem of existing complexities and leaks. The invention is achieved by a lid (300) having a lid skirt (320) provided with an inner collar (328) that engages an outer collar (222) of a sidewall (220) of a pail (200), the lid skirt (320) being provided with a fastening mechanism (330) for tightening the inner collar (328) around the sidewall (220) below the outer collar (222). Corresponding to the lid (300) a pail (200) is provided having a simplified structure that is supported mechanically by the lid (300). Furthermore, a thermally insulated compound pail is disclosed, the compound pail comprising a first inner pail (200) that is inserted into a second outer pail (200) such that a space (404) is formed between said pails (200).
