Medical device for preserving explanted corneas, serving as a viewing chamber, comprising a sealed outer main case (2) which contains a container (3) for preserving and viewing a cornea which comprises a vessel (4) which inside it forms a preserving chamber, (11), a supporting unit (12) for a corneoscleral disc positioned in the preserving chamber (11), and a first lid (5) removably joinable or joined to the vessel (4); the medical device (1) being ready for use and also comprising a first locking ring (18) which is joinable or joined to both the first lid (5) and to the vessel (4), outside them, and is breakable or deformable; wherein when the first lid (5) is joined to the vessel (4) and the first locking ring (18) is joined both to the first lid (5) and to the vessel (4), in an intact and non-deformed condition, the first locking ring (18) prevents removal of the first lid (5) from the vessel (4), whereas in a broken or deformed condition, the first locking ring (18) allows removal of the first lid (5) from the vessel (4).

The present invention relates to a food packaging comprising a first par-tial shell, which has a first depression and a first flange delimiting said first depression; a second partial shell, which has a second depression and a second flange delimiting said second depression; the first and second partial shells being coupled to each other via their flanges thus defining a cavity for holding food. The invention relates to novel types of packaging and partial shells. The first partial shell can be made of a material that is different from that of the second partial shell. The partial shell can have a window that consists of a first material which is different from a second material that forms at least one outer surface of the partial shell. The flange can have a first region that consists of a first material and a second region that consists of a second material.

Disclosed is a double-wall vacuum-insulated food container with complementary lid. The body of the container has a base and an upwardly-extending side wall terminating in an upper free edge. The container also has an inner portion and a complementary outer portion with a gap between. The lid sealingly fits onto the upper free edge of the container. The lid includes a central member and a surrounding frame with a sealing ring. The sealing ring serves as an interface between a lower peripheral edge of the frame and the upper free edge of the container. The frame has fastening members which complementary features disposed about the upper free edge of the container. Within the container is a separator having an outer profile substantially complementary with an inner contour of the container, whereby the interior of the container may be selectively divided by a user.

Disclosed embodiments include a structural assembly having a first panel having a first edge and a first aperture adjacent to the first edge, and a clamp having a first piece that passes through the first aperture, a second piece, and a fastening portion that fastens together the first piece and the second piece. The structural assembly may include a second panel having a second edge and a second aperture adjacent to the second edge, and the second piece passes through the second aperture, and the clamp holds the first panel and the second panel together.

A sealable container system contains a body and a lid assembly. The body includes an internal volume defined by a bottom and side wall(s) and divot(s) with a cavity at an upper edge of and in an inside surface of the side wall. The lid assembly includes a lid with outer and inner walls at its bottom side with a channel in-between. A gasket couples to the lid with a wall portion residing within the channel and a lip outside the channel. When the lid assembly is pressed into the body, the lip of the gasket abuts the divots and forms a gap with the side wall, where air in the internal volume exits through the gap. When the lip travels past the divots, the lip fully seats against the inside surface of the side wall, and negative air pressure is imparted to the internal volume of the body.

The present disclosure provides a chemical container and a method for manufacturing the same. The chemical container comprises a head portion having a top wall and a head sidewall extending from an edge of the top wall, as well as a body portion jointed with the head portion and defining a chamber together with the head portion. The top wall has a mouth structure configured for one or more pipelines to pass through and connect with the chamber. The manufacturing method is simple and of low cost, and the resulted chemical container is able to withstand a greater internal pressure and is configured to collect any leaking liquid chemicals.

Methods and apparatus for providing a collapsible cargo box. The cargo box include a left wall having a tongue at the rearmost portion and a tongue at the bottom, a right wall having a tongue at the rearmost portion and a tongue at the bottom, a rear wall having a tongue at the leftmost portion, the rightmost portion and the bottom, a base and a tailgate. The method may include sliding the tongue at the bottom of the left wall into a first groove in the base, sliding the tongue at the bottom of the rear wall into a second groove in the base, sliding the tongue at the bottom of the right wall into a third groove in the base, rotatably coupling the tailgate to the base, coupling the left wall to the rear wall and coupling the right wall to the rear wall.

The modular panel 20 interlocking and reinforcing mechanism for building enclosures pertains to assembling boxes 21 with six of the same or similar modular panels 20 without extra components or connectors. My mechanism joins modular panels 20 by interlocking both grooves 22 attached by living hinges 24 on the panel edges, thus creating the box 21.

The embodiment of my mechanism joins modular panels 20 by interlocking both grooves 22 attached by living hinges 24 on the panel edges, thus creating the box 21. The living hinges 24 allow all the grooves 22 to turn forty five degrees at the corners. Upon interlocking both grooves 22 to each other at a forty five degree angle, it completes the ninety degree dihedral angle transition from one panel 20 to another for corners. Another embodiment of my mechanism is to assemble a box 21 in expanded sizes by using the same or similar modular panels 20 without extra accessories. Modular panels are connected side by side to expand the flat surface or transitioning to a ninety degree angle at the box corners. An additional embodiment of my mechanism includes similar sized reinforcing rods 30 embedded in the interlocked grooves 26, which allows them tightly interlock together and strengthen the box 21. One type of the interlocking groove 22 mentioned above is round with a narrower outer opening than the inner width.

The invention relates to a fuel tank of thermoplastic polymer for a motor vehicle, having at least one reinforcing element inside the fuel tank, the reinforcing element inside the fuel tank extending between opposing tank walls (15), parts of the reinforcing element passing through the tank wall and parts of the reinforcing element engaging behind the tank wall from outside, the fuel tank being distinguished according to the invention in that the reinforcing element (8) is provided with at least one multipart fastening head (11), which comprises a first closing means engaging through the tank wall (15) from inside and a second closing means engaging through the tank wall (15) from outside, which closing means are of mutually complementary construction.
