The document relates to a method of making a disposable double walled structure comprising an inner wall portion (51) surrounding a product space presenting a cross section and extending along an axial direction, perpendicular to the cross section, between first and second axially spaced apart portions, and an outer wall portion (52) at least partially surrounding the inner wall portion (51), wherein an insulating space is formed between the inner and outer wall portions. The method comprises forming the inner and outer walls (51, 52) in one piece, such that the inner and outer walls are connected at the first axial portion and at least partially overlap as seen in a direction perpendicular to the axial direction, and bending at least one of the inner (51) and outer (52) wall portions in the direction perpendicular to the axial direction towards the other one of the inner (51) and outer (52) wall portions at the second axial portion, so as to form the insulating space.

A three-dimensional, vacuum thermal insulating element comprising a compressed three-dimensional porous structure, an envelope closed in an airtight manner comprising a thermoformable barrier wall, enclosing the porous structure, which is interposed between two major surfaces of the barrier wall, and where, at outside ambient temperature and pressure, a pressure between less than 10.sup.5 Pa and more than 10.sup.−2 Pa prevails. The barrier wall is thermoformed at said the two major surfaces, between which the porous structure is bent-shaped and/or has reliefs and/or depressions.

A composite table top including a top plate having an outer and an inner surface, a bottom plate comprising a plurality of projections, each of the plurality of projections having a top defining a top surface. The composite table top has at least a pair of reinforcement inserts disposed at two opposite edges of the bottom plate. The sum of the top surfaces of the plurality of projections is 30%-70% of the upper surface of the bottom plate.

A fluid chamber for a shoe may be formed using pressure channels in a forming mold, eliminating the need to insert a nozzle or needles into the chamber for inflation. A fluid chamber so formed may have a smaller seal area than a chamber formed using an inflation needle, making the chamber more visually pleasing. Apparatus and methods for forming a fluid chamber in this fashion are also disclosed.

A fluid chamber (20) for a shoe may be formed using pressure channels (190) in a forming mold (100A), eliminating the need to insert a nozzle or needles into the chamber for inflation. A fluid chamber so formed may have a smaller seal area than a chamber formed using an inflation needle, making the chamber more visually pleasing. Apparatus and methods for forming a fluid chamber in this fashion are disclosed.

A method of manufacturing a wearable article may include providing a modular mold assembly that defines a mold cavity. The modular mold assembly may include a base and a first removable mold tool that interfits with the base. The base may have a mold surface partially defining the mold cavity and the first removable mold tool may have a mold surface disposed at and further defining the mold cavity of the modular mold assembly. A topography of the mold surface of the first removable mold tool may be nonuniform and different than a topography of the mold surface of the base. The method may include disposing polymeric material at the mold cavity, and then thermoforming a bladder in the mold cavity from the polymeric material. The bladder may have an outer surface with a nonuniform topography imparted by the topography of the mold surface of the first removable mold tool.

A three-dimensional vacuum thermal insulation element having a compressed three-dimensional porous structure and a shell closed in an airtight manner. The shell includes a thermoformable barrier wall and encloses the porous structure arranged between two major surfaces of said barrier wall. The porous structure has a pressure of between less than 105 Pa and more than 10-2 Pa at ambient external temperature and pressure. The barrier wall is thermoformed at the site of said two major surfaces, between which the porous structure has a curved shape and/or reliefs and/or depressions.

A table has a bottom plate having a bottom plate channel and an outer wall. A bottom plate lip is perpendicular to the outer wall. A top plate has a top plate lip overlying and parallel to the bottom plate lip. A lower end of a frame is in the bottom plate channel and an upper end of the frame is in contact with the top plate. An edge piece clamps the top plate lip and the bottom plate lip together. The edge piece extends entirely around a perimeter of the top plate.

A three-dimensionally shaped assembly comprising fibres in a three-dimensional structure, and a sleeve comprising a polymeric film and which encloses the fibrous structure, the shape of which is followed by the polymeric film.
