摘要： Method of blow moulding a container from a hollow, elongated parison of a thermoplastic material, wherein the method comprises: —arranging the parison in a closed moulding equipment comprising a moulding cavity and at least one aperture, wherein the at least one aperture provides an opening into the moulding cavity from outside the closed moulding equipment, wherein the circumference of the at least one aperture is larger than or equal to a circumference of the parison, such that a first section of the parison is arranged inside the moulding cavity, a second section of the parison is arranged within the at least one aperture and a third section of the parison is arranged outside the closed moulding equipment, —closing a shutter system around the third section of the parison, thereby pinching the parison and providing a closed volume inside the first and second sections of the parison, —arranging a blow conduit in fluid communication with the closed volume inside the second section of the parison, —blowing pressurised gas from the blow conduit into the first and the second section of the parison, thereby forming first and second blow moulded sections, wherein the first blow moulded section is the container, and—separating the second blow moulded section from the first blow moulded section, thereby providing an opening in the container.

摘要： A method of forming a container includes blow molding a primary form of the container inside a primary mold. The primary form has an exterior surface. The method also includes applying a fluid to the exterior surface of the primary form to shrink the primary form and to form a shrunken form of the container. Furthermore, the method includes blow molding a secondary form of the container from the shrunken form inside a secondary mold.

摘要： A method of forming hollow tubular members may include providing a mold defining a surface corresponding to a configuration of the hollow tubular member. A fabric material may be placed in the mold for bonding with a resin to form the hollow tubular member. A bladder may be placed in the mold next to the fabric material to form a substantially air tight region around the fabric material. A pump may be used to apply a sub-atmospheric pressure in the substantially air tight region and thereby press the fabric material against the mold. The sub-atmospheric pressure may also be used to draw the resin material into the mold in contact with the fabric material. Once the resin and fabric material have adequately cured, the hollow tubular member may be removed from the mold.

摘要： A stress-softened thermoplastic elastomeric (TPE) film which has been subjected to tensional deformation comprising at least uniaxial strain, and having improved textural and thermal transmissivity characteristics, as compared to a native, unstretched material. Such stress-softened thermoplastic elastomeric film may be employed in a wide variety of articles, including condoms, finger cots, tubular bandages, and the like. Condoms comprising such stress-softened TPE film are described, including condoms having a main sheath comprising stress-softened and non-stress-softened areas in a pattern or other predetermined arrangement. A variety of methods and apparatus for forming stress-softened tubular articles of thermoplastic elastomeric film is disclosed.

摘要： Condoms are disclosed of the type having a main sheath portion closed at a distal end and open at a proximal end thereof, which are amenable to construction from thermoplastic elastomeric materials. In one preferred aspect, such condoms have an annular-shaped sealing element, formed of an elastic material, circumscribing an interior opening of smaller size than the proximal end opening of the condom, and joined at the outer periphery of the sealing element to the main sheath, at or in the vicinity of the proximal end opening. Such construction thereby provides a membrane dam in the proximal segment of the condom to enhance its effectiveness as a contraceptive and to minimize the incidence of sexually transmitted diseases. Also disclosed are various condom manufacturing and processing apparatuses, as well as applicators for applying the condoms to the penis of a wearer.

摘要： A method of forming a hollow reinforced fiber structure includes the steps of providing fiber reinforced material around a flexible expandable member and placing the resulting package inside of a mold which includes inner surfaces conforming to the shape of the structure being formed. A second expandable means is included in the mold on both sides of the package. After the mold is closed, pressure is applied to force the second expandable means against the fiber reinforced material. Resin is injected into the fiber reinforced material. The pressure is then decreased in the second expandable means as inflatable member is expanded to force the fiber material to conform to the inner surfaces of the mold. The fiber material is then cured to form the structure.

摘要： This invention controls the application of a parison to a core rod in the cavity of the injection mold of injection blow molding apparatus. The invention is particularly useful for core rods that include a balloon which covers the outside surface of the core rod and over which the parison is applied. Elastomer material of which the balloon is made is eventually eroded by the hot blast of plastic injection against the end of the core rod in the conventional manner. This invention covers most of the core rod with a protecting metal tube in the mold cavity and applies the plastic as a rolling wave instead of a blast impact.
