A method of manufacturing a cover for a spa includes the steps of vacuum molding a first shell member and a second shell member, bringing the first and second shell members into registration with one another to define a hollow cavity therebetween, and injecting a foam into the hollow cavity, wherein the foam is configured to bond with the shell members to create a unitary structural part that provides increased strength and rigidity.

The invention relates to a method for impregnating a polymer granulate with a predefined mass of a gaseous propellant. According to the invention, the polymer granulate is arranged inside a pressure vessel and a gaseous propellant is introduced into the inside of the pressure vessel.

A patterning method using an imprint mold, to form an imprinted pattern structure, includes providing a resist layer from which the pattern structure will be formed, performing a first imprint process on a first area of the resist layer by using the imprint mold to form a first pattern of the pattern structure through deformation of the resist layer in the first area, and performing a second imprint process on a second area of the resist layer by using the imprint mold to form a second pattern of the pattern structure through deformation of the resist layer in the second area. The first and second areas are overlapped with each other in a third area of the resist layer, and the performing the second imprint process deforms a first portion of the first pattern in the third area to form the second pattern.

A fluid container having a proximal end having an end wall, a distal end having an open-ended neck, and a sidewall extending between the proximal end and the distal end along a longitudinal axis is described. A localized crystallinity of a polymeric material of the fluid container of at least a first region of the fluid container is greater than a crystallinity of a polymeric material of the fluid container of at least a second region. Examples of fluid containers include medical fluid containers, such as medical bottles and syringes, including rolling diaphragm-type syringes, and commercial beverage containers Articles of manufacturer formed form a polymeric material and having regions with increased localized polymeric crystallinity are also described.

Embodiments of the disclosure relate to a blister package having a laminate structure that is heat-sealable to a lacquer layer on strain-hardened aluminum foil. The blister package includes a lid layer comprising a strain-hardened aluminum foil, a lacquer layer on a sealing surface of the strain-hardened aluminum foil and a laminate structure sealed directly to the lacquer layer. The laminate structure includes a multilayer film and a plurality of wells formed therethrough. The multilayer film includes a first formable layer of a thermoplastic material and a sealing layer of a copolyester material. The sealing layer overlies the first formable layer and has an outer surface opposite the first formable layer. The sealing layer has crystallinity from 5% to 20% as measured by differential scanning calorimetry (DSC). The outer surface of the sealing layer is sealed directly against the lacquer layer.
