A combined device of a box is composed of soft and elastic materials, and includes: a lid; a shell body, the lid covers the shell body to form the box; at least one fastening portion; The fastening portion is accommodated in an accommodating cavity of the buckle slot, and the width as clamping for the buckle slot to hook and contact is less than or equal to the width for the fastening portion to hook and contact, so as to fix the lid and the shell.

Disclosed is an airtight container including a main body with an opening, and a cover, the airtight container including: an edge portion to press a sealing edge formed at an upper end of the main body; a locking clamp including an engaging portion to engage with an engaging-portion holder extended from the sealing edge or formed in a lateral wall; and a hinge provided between the edge portion and the locking clamp and including a material to be folded and unfolded with respect to the edge portion so that the engaging portion can be locked to and released from the engaging-portion holder. Thus, there is provided an airtight container with a soft hinge and a double injection-moulding structure, which is improved in durability because the hinge is prevented from damage even though it is used for a long time.

The present application discloses a container, having a housing with a housing bottom wall and a housing sidewall, and a liner having a liner bottom wall and a liner sidewall. The liner is detachably connected to the housing sidewall, so that the liner is received in the housing chamber. At least a portion between the housing sidewall and the liner sidewall has a gap therebetween. This application discloses a double-layer container having a liner and a housing detachable with each other, so that the housing can use a combination of different shapes of the liner. At the same time, the liner of the container in the present application is made of a flexible material to facilitate cleaning of the liner. On the other hand, the double-layer container of the present application can directly use the liner as a seal, which is convenient for cleaning.

A sterile container and a closure mechanism for the sterile container. The sterile container includes a container pan and a container lid. The container lid is lockable to the container pan by the closure mechanism. The closure mechanism has a bar element for undercut engagement with an engagement element arranged on the container pan or on the container lid and which forms an undercut. The bar element is positionable in a closed position, in which the bar element is operatively engaged with the engagement element via the undercut, and in a release position, in which the bar element and the engagement element are disengaged. The closure mechanism includes a locking element that is operatively connectable to the bar element and which is integrated into the closure mechanism in such a way that the locking element blocks the closure mechanism when the closed position is reached.

An interbox connector used in intermodal transportation systems is provided. The interbox connector is adapted to secure a top container to a bottom container in which the top container and bottom container each have corner castings. A plate is configured to be positioned between a corner casting of the bottom container and a corner casting of the top container prior to the top container being stacked on the bottom container. A first latch extends upwardly from the plate in which the first latch is configured to be disposed in the corner casting of the top container. A second latch extends downwardly from the plate in which the second latch is configured to be disposed in the corner castings of the bottom container. Placement of the top container on top of the bottom container causes the second latch and the first latch to automatically rotate and secure the top container to the bottom container.
