A battery assembly according to an exemplary aspect of the present disclosure includes, among other things, a battery array and a foam shell that surrounds the battery array.

A method and apparatus for the formation of double-walled containers with the structure of two integrally connected and adjacent containers extending in the same direction with an air gap between them, stretch-blow moulded as single bodies out of thermoplastic material, and suitable for mass-production. A thermoplastic tubular blank is formed and then heat-conditioned. The heat-conditioned tubular blank is then mechanically stretched longitudinally and blow-formed outwards by gas pressure to conformingly and stretchingly assume the tubular blank to the shape of a first dual-container shaped mould cavity set in order to form a stretch-blow moulded first container integrally connected to a second container, with both containers extending in opposite directions. Next, additional heat-conditioning is applied to further heat-condition as necessary the stretch-blow moulded second container and if deemed an advantage, at least part of the first container. Then at least one profiled inversion piston shaped as a male mould member with an outer surface configuration that defines the inner surface configuration of the article being formed and a second container shaped mould cavity set with a single-container shaped configuration are provided along with one or more wall stability devices which are applied to at least part of the wall surface(s) of either or both of the two integrally connected stretch-blow moulded containers, such that the second smaller container side wall(s) are at least substantially not in contact with the second container shaped mould cavity set and may be inverted at least partially inside-out, while at the same time the second smaller container bottom wall at least substantially does not invert, in order for the second smaller container to become a substantially mirror-image inverted second smaller container extending in the same direction as, and interior to, the first container.

In one embodiment, a method of forming a rigid package includes positioning a label with a plastic outer surface within a mould, positioning a PET sheet over the mould, contacting a first surface portion of the plastic outer surface with a second surface portion of the PET sheet, wherein at least one of the first surface portion and the second surface portion has a surface energy modified by a surface energy treatment, thermoforming the positioned PET sheet in the mould, and direct bonding the first surface portion and the second surface portion.

A thermally expandable sheet includes: a first thermally expansive layer that is formed on one side of a base and contains a first thermally expandable material and a first binder, the first thermally expansive layer having a first ratio of the first thermally expandable material with respect to the first binder; and a second thermally expansive layer that is formed on the first thermally expansive layer and contains a second thermally expandable material and a second binder, the second thermally expansive layer having a second ratio of the second thermally expandable material with respect to the second binder, wherein the first ratio is lower than the second ratio.

A battery assembly includes a battery array and a foam shell that surrounds the battery array. The battery array may be housed within a foam shell, and a barrier can be secured to the foam shell to establish a battery assembly. The battery assembly may then be secured to a vehicle body.

A getter assembly is provided and includes a first canister, an internal can including getter, and a second canister. The internal can is disposable in the first canister to occupy a first position at which the getter is hermetically sealable and second positions at which the getter is exposed to an exterior environment. The second canister is engageable with the first canister to drive movements of the internal can between the first position and the second positions following activation and hermetic sealing of the getter.

A preform formed from polypropylene or high density polyethylene and with which a container of a desired shape can be precisely molded by liquid blow molding. When formed of polypropylene as a closed-bottom cylinder shape having an open end section and a body section, the preform is molded into the container by stretching the body section in the axial direction by a stretch ratio of 2.25-4.34, inclusive, and in the radial direction by a stretch ratio of 1.95-5.00, inclusive. When formed of high density polyethylene as a closed-bottom cylinder shape having an open end section and a body section, the preform is molded into the container by stretching the body section in the axial direction by a stretch ratio of 1.69-2.50, inclusive, and in the radial direction by a stretch ratio of 2.26-5.07, inclusive.

A method for producing a container having a threaded wide neck, includes steps of: heating a preform having a polyester body, on which there is mounted a polyolefin sleeve positioned next to an area of the body corresponding to the wide neck of the container; introducing the heated preform, with the sleeve, into a mould having the footprint of the container, including a threaded area having the footprint of the wide neck; injecting a pressurised fluid into the preform in order to form a blank of the container including a lower portion including the wide neck with a thread formed in the sleeve and an upper portion above the wide neck; separating the upper portion from the lower portion that thus forms the container.

A compound type polyurethane toilet seat, comprising a surface coating layer, a positioning structure and a seat support; the surface coating layer is made from polyurethane and seamlessly covers the outer surface of the seat support by means of the positioning structure; the preparation process comprises: step 1, spraying a release agent and an in-mold paint in a cavity of a mold; step 2, cleaning the surface of the seat support; step 3, polishing or abrasive blasting; step 4, thermally treating the seat support; step 5, spraying the release agent in the cavity of the mold, and installing the seat support in the cavity of the mold; step 6, injecting a polyurethane raw material into the cavity of the mold, and shaking the mold; step 7, foaming the polyurethane raw material.

A tubular irrigation device, such as a pipe or sleeve, having a circular multilayer polymeric structure including one or more layers of woven polymeric thermoplastic materials, one or more layers of thermoplastic polymeric materials, and one or more layers of polymeric waterproofing materials in film form. Methods of making the tubular irrigation device are also described.
