A receptacle including a body configured to receive refuse items and a mated handle is disclosed. The handle includes a base plate and a gripping portion connected by one or more sidewalls. The back side of said base plate contains a projection to allow the handle to mate with the body of the receptacle. The projection includes two regions offset from each other so that, when the body of the receptacle is formed by blow molding, the body can fill around the projection, thereby securely attaching the two. The handle can further include a cinch so that if a liner is used within the body of the receptacle, there is a place to tie it off on the handle. Multiple handles can be mated to a single receptacle body.

An insulating coated wire includes a center conductor and an insulating coating. The insulating coating has a bending auxiliary section in which the thickness of the insulating coating is smaller than that of the other portion, and that has a shape in which at least a part thereof protrudes outward in the radial direction. The bending auxiliary section has a shape that facilitates bending of the insulating coated wire by elongation deformation thereof. This insulating coated wire can be manufactured by arranging, on the circumference of an insulating coated wire material, a metal mold that has the inner surface including the section having a shape protruding outward in the radial direction, and forming the bending auxiliary section in the shape along the inner surface of the metal mold by heating the insulating coating within the metal mold and generating a pressure difference between inside and outside of the insulating coating.

Disclosed are a valve device and a blow molding system. The valve device is used in a blow mold and one or two decorative labels for affixing to a bottle body are placed in the blow mold. The valve device comprises a base and at least one pin arranged on the base, wherein the pin is inserted into a vacuum suction hole of the blow mold. The valve device opens the vacuum suction holes to create negative pressure and enable a decorative label to be adsorbed to the inner wall of the blow mold, and blocks the vacuum suction holes to achieve detachment between the decorative label and the inner wall of the blow mold, thereby adhering the decorative label to the bottle body to complete the production.
