An apparatus and method of forming a container from a preform having a closed end, an oppositely disposed open end, a body portion extending from the closed end and terminating in a neck finish portion at the open end, the preform having at least one inner diameter. A mandrel is provided having a tapered portion at one end thereof and at least one outer diameter greater in size than the at least one inner diameter of the preform. The mandrel is moved into the open end of the preform to expand the neck finish portion of the preform. The mandrel is further moved into the preform to also expand the body portion of the preform until the one end of the mandrel at least partially forms the closed end of the preform into an at least partially formed closed end of the container, after which the mandrel is removed from the container. According to a preferred embodiment of the present invention, the tapered portion of the mandrel may be collapsible into a body portion of the mandrel in order to finish form the closed end of the preform.

In this method, a delamination resistant three dimensional double curvature surface colored composite article is made by providing a membrane with a delamination-resistant coloring coating and applying the membrane to an injection mold having mold halves, a mold parting face, mold cavity edge and a mold cavity therein for the formation of an injection molded article, and injecting molten plastic into the mold cavity in order to form a three dimensional double curvature surface composite article with the membrane bonded to the injected plastic. Alternatively, the membrane is thermoformed.

A method of producing contoured vehicle floor mats having integrally formed nibs. The sheet is formed by a nib forming roll in an extrusion roll stack having a plurality of indentions. The nibbed sheet is placed onto the thermoform mold with the nibs directed away from the mold. The sheet is heated to a plastic state and stretched over the mold to form a contoured mat shaped to vehicle within a vehicle compartment, trunk or cargo area. The nibs on the underside of the mat contacts the floor covering and prevents the mats from sliding on the interior surface of the vehicle.

To provide a mouth guard-preparing sheet from which a mouth guard to be used for preventing teeth and their surrounding tissues from a trauma occurred mainly in sports and having a uniform thickness between the right and left sides thereof can be prepared, without causing a problem in the thickness of an anterior teeth portion becoming thin in the preparation of a custom-made mouth guard by heat-sucking. The mouth guard-preparing sheet is made of a thermoplastic resin having a plane shape substantially coincident with a shape of a fixed frame of a heat-sucking type mouth preparation device and provided with a mouth guard portion from a site to be contacted with a labial surface side of a gingiva of an anterior teeth portion to a molar portion side and an elongation tab portion in an exterior direction of a mouth guard portion, wherein said mouth guard portion has a thickness of 1.5˜10 mm; said elongation tab portion has a thickness of 0.1˜0.95 times the thickness of said mouth guard portion; and a stepped portion between the mouth guard portion and the elongation tap portion is in a straight line.

There is provided a container system adapted to withstand a single impact or repeated impacts. The container system possesses one uniform wall thickness throughout the entirety of its body so as to be impact-resistant. The container system features a first container having a first container body and a second container having a second container body. The second container defines a second body height and a second body wall thickness. A body recess adapted to releasably engage the first container body is formed on the second container body and is extended along the second body height. The body recess defines at least one recess bottom corner having a recess bottom corner wall thickness which is at least substantially similar to the second body wall thickness of the second container body. This specified bottom corner wall thickness of the body recess allows the second container to withstand the single impact or repeated impacts.

Introduction guides 12 are provided above and below a sheet-introduction opening portion of a pressure-reduced chamber 10, and heating means 17 is provided between the introduction guides. Each resin sheet 3 is attracted and attached respectively to the circumferential surface of a corresponding emboss roller 11 by reducing pressure. Pins 112 of the emboss roller 11 are truncated cone-shaped. The ratio of the total area of the lower bases of the pins 112 to the area of the circumferential surface of the emboss roller is 0.5 or more. The rising angle θ of the pin side face, in the vertical plane including the central axis of the pins 112, is in the range from 50 degrees to 70 degrees. Furthermore, a multilayered hollow structure plate 140 is formed by attaching non-air-permeable sheets 130 onto both the front and back of a core member obtained by fusing together hollow protrusions 112 in two thermoplastic resin sheets. A sound absorbing material 150 is provided on at least one of the front and back side thereof, and small holes 114a opened in the multilayered hollow structure plate are formed in liner portions 114 and the non-air permeable sheet 130 only in the positions that matches the liner portions 114.

Provided is a container system adapted to withstand repeated impacts. The container system features a first container having a first container body and a second container having a second container body. The second container defines a second body height and a second body wall thickness. A body recess which is adapted to releasably engage the first container body of the first container is formed on the second container body and is extended along the second body height. The body recess defines at least one recess bottom corner having a recess bottom corner wall thickness which is at least identical to the second body wall thickness of the second container body. This specified bottom corner wall thickness of the body recess allows the second container to withstand the single impact or repeated impacts. Polyethylene, extrusion blow-moldable copolyester, polycarbonate, and clarified polypropylene may be used to fabricate the second container.
摘要:
A fluid-filled chamber for an article of footwear and a method for manufacturing the chamber are disclosed. The chamber may be incorporated into a sole structure of the footwear and includes a central area and a plurality of lobes extending outward from the central area. The lobes are in fluid communication with the central area and are formed from a first surface, a second surface, and a sidewall. The sidewall joins with the first surface with the second surface to seal the fluid within the chamber, but no internal connections are generally utilized to join interior portions of the first surface with interior portions of the second surface. The fluid within the chamber may be air at a pressure that is approximately equal to an ambient pressure.
