Pressure packaging with improved drop resistance and impact resistance

A multi-layered pressure packaging comprises a first container including a lockable neck portion followed by a body part and a bottom part, obtained from a non-foamed thermoplastic material by stretch blow molding, and a first layer at least enclosing the body part and/or bottom part of the first container. The first layer comprises foamed material, and the foamed material layer is foamed in place with an outer enclosure applied over and around the first container defining a free space in between, and foamable material introduced and foamed between the first container and the outer enclosure in the free space, obtaining the foamed material layer. A second layer is applied on the outer surface of the foamed layer for keeping the foamed layer and the first container together. Methods are provided for manufacturing a multi-layered pressure packaging according to an embodiment.

COOLING TANK, WATER PURIFIER HAVING SAME, AND COOLING TANK MANUFACTURING METHOD

Provided is a cooling tank comprising a tank body in which a water accommodation space is formed, a foaming case for encompassing the outer peripheral surface of the tank body, and a foam insulating material formed by a foaming agent flowing into the foaming space between the outer peripheral surface of the tank body and the foaming case, and then foaming, wherein the foam insulating material is integrated with the tank body and the case through foaming, and the case has an air outlet through which air of the foaming space is discharged during a foaming process.

METHOD FOR MANUFACTURING A COMPOSITE PART AND USE THEREOF

For manufacturing composite parts (1) having an inner hollow moulded body (2) with openings (3), which are accessible from outside, the moulded body is introduced into a moulding tool on the mould walls on which a shell layer (11) was applied. The hollow space between the moulded body (2) and the shell layer (11) is filled with a thermally insulating plastic foam (12) which is foamed in the moulding tool and bonds to the moulded body and the shell layer. After removal, a moulded body is provided, which has a qualitatively good surface formed by the shell layer. Such a composite part is preferably used for connecting thermally insulating pipes.

Included are a first board having a hard polyurethane foam layer formed in a space sandwiched between a pair of thin plates, and a second board having a porous structure where a recessed groove is formed in one main surface, a part of the second board being arranged in the space and joined to the first board. The hard polyurethane foam layer is also formed in gaps between the thin plates and the second board to join the boards. Thus, the step of molding the first board can join and integrate the boards, and mold a bendable, lightweight, and very strong vehicle interior board. Therefore, the vehicle interior board can be reduced in number of parts, simplified in manufacturing process, and improved in productivity.

ANNULAR REINFORCEMENT STRUCTURE

An annular reinforcement structure is provided having an inner reinforcement band, an outer reinforcement band positioned around and concentric with the inner reinforcement band, and a cast-in-place polymer foam spacer, which maintains the spatial orientation of the inner and outer reinforcement bands. The annular reinforcement structure may be embedded in an elastomeric matrix material to provide stability, such as for belt for power transmission.

A container, that includes a transparent portion, which reveals an interior portion of the container, an access aperture communicating with the interior portion of the container, and a lid adjacent the access aperture. A first liquid component is placed into the interior portion. A second liquid component is poured into the interior portion. The lid of the container is closed to fully enclose the first and second liquid components. The components are agitated until the first and second liquid components are a mixture of uniform color, without an appearance of marbling and swirling, when viewed through the transparent portion of the container. The lid is opened to expose the mixture of uniform color. The mixture of uniform color is poured from the container into a receiving structure. The mixture of uniform color is transformed into a closed-cell polyurethane structure within the receiving structure.

Apparatus and method for manufacturing insulated pipe assembly
10737309 · 2020-08-11 · ·

An apparatus and method for manufacturing a pipe assembly having an inner pipe and an outer jacket may include a support member, a pair of lance assemblies and a pair of caps. The support member supports the outer jacket of the pipe assembly and is drivable between a first position and a second position. The pair of lance assemblies are configured to be inserted into opposing ends of the inner pipe such that the pair of lance assemblies engage an inner wall of the inner pipe. One of the outer jacket and the inner pipes moves relative to the other of the outer jacket and the inner pipe to center the inner pipe within the outer jacket when the support member is driven from the first position to the second position. Insulation is inserted through at least one cap into a space between the inner pipe and outer jacket.
