A housing includes: a housing body that contains at least one electromechanical or mechanical component, the housing body including a front plate and a pair of side plates, the plates being connected to a bottom plate in such a manner that the housing body includes an opening; a cover for closing the opening; and a gasket interposed between an edge portion of the housing body and an edge portion of the cover to tightly close an inside of the housing body. An edge portion of each of the side plates has a curved shape.

Provided is a container including a rigid wall portion having an opening, a flexible wall portion having a corresponding opening coupled to the opening of the rigid wall portion; and a support member coupled to the rigid wall portion configured for providing the container with stability. The rigid wall portion and the flexible wall portion form together a structure configured for holding fluids.

A fluid reservoir assembly, for containing a fluid such as a lubricant is disclosed with a first end plate, a body and a second end plate. The body is preferably formed from plastic or glass. The end plates are composed of a molded plastic resin and are sealingly fastened to the body with an adhesive. The reservoir assembly has an inlet and outlet. Depending upon the configuration of the end plates and body, reservoirs of various sizes, capacities and cross-sectional shapes (e.g. circular, rectangular, etc.) can be fabricated without the need for dedicated molds and specialized tooling.

The invention relates to a plastic vessel comprising a metal element (3) which is accommodated its base (10), wherein the plastic vessel comprises a vessel element (1) and a cover (2), such that the plastic vessel is formed in two pieces, and wherein a recess (12) is formed in the base (10) of the vessel element (1), said recess (12) being enclosed by the cover (2) such a that a central closed region (14) of the recess (12) is provided, which accommodates the metal element (3), and wherein the vessel element (1) and the cover (2) are connected to one another thermoplastically under pressure.

The vessel element (1) and the cover (2) are particularly made of polycarbonate or copolyester, and the plastic vessel is in particular a drinking glass, and the metal element (3) is in particular a neodymium magnet having a copper-nickel coating. Moreover the invention relates to a method for producing a plastic vessel while using the thermoplastic properties of the plastic, and to the use of the vessel in interaction with a suitable means of transport and/or in a vehicle of any kind and/or for the usage by persons with reduced motor skills and/or perception and/or attention and/or as a decorative element.

Specific composite materials described herein are based on the discovery that certain selections of materials and manufacturing conditions and processes provide unexpectedly improved self-supporting thin-film composite materials. It has been discovered that certain combinations of backing materials, shrink film materials, and manufacturing conditions provide improved composites having highly controllable, readily repeatable, and stable arc shaped cross-web curled structures. In general, the composite materials described herein comprise a dimensionally alterable film such as a polyester shrink film having a first surface and a second surface, and a polyester backing material having a first surface and a second surface, wherein the second surface of the backing material is laminated to the first surface of the dimensionally alterable film. Upon activation of the alterable film, for example upon exposing the composite material comprising the polyester heat shrink film to heat, the composite material can be imparted with an arc shaped cross-web curled structure along it longitudinal width, resulting in resistance to bending in its axial length, and a self-supporting material.

The various embodiments described herein include aluminum cups and method and materials to form aluminum cups. In one aspect, an aluminum cup includes a cup side wall including an aluminum foil layer, a first polymer layer, and a second polymer layer. The first perpendicular edge of the cup side wall can be heat-bonded to the second perpendicular edge of the cup side wall, bonding the first polymer layer to the second polymer layer.

The utility model discloses a multi-layer nested inner container easy to disassemble and clean and a sperm extractor comprising the same. A soft cup is arranged in a cavity of a hard inner long cylinder in an interference fit manner to form a detachable assembly; the soft cup can be well fixed by means of the hard inner long cylinder, and the soft material of the soft cup makes the interference fit structure easy to assemble and stable; and an outer surface of the hard inner long cylinder is provided with stoppers, and the stoppers abut against an outer cylinder to form interference fit. In this way, when the soft cup is pulled out, the hard inner long cylinder can be used as an acting point, which facilitates assembly and cleaning. In addition, the snap fit assembly mode is simple, so assembly efficiency is improved.
