Abstract: An ink tank producing a stable negative pressure regardless of material used is provided. In the ink tank, inner and outer walls include a bonding region having a bonding force distribution. With this arrangement, since the inner wall separates from the outer wall as ink in the ink tank is being guided out, the area of a non-bonding region increases.

Abstract: A double-wall fuel container of plastic material is composed of at least two shell portions which are welded together. The half-shell portions are each in the form of double-wall blow moldings, with a gap being kept free at least in a region-wise manner between the walls of the blow moldings.

Abstract: A container blank comprises at least one substrate layer made of disposable material and at least one film layer disposed substantially over the substrate layer and having at least one portion adapted to shrink away from the substrate layer upon application of heat. The shrunk film layer portion is adapted to thermally insulate the substrate layer located substantially behind the shrunk film layer portion.

Abstract: A disposable cup comprises a side wall having an outer surface, an inner surface, and at least one air pocket formed on the inner surface. The air pockets are formed by shrink film being adhered to the inner surface in at least one pattern and adapted to pull away from the inner surface in accordance with the pattern upon application of heat at a temperature range sufficient to cause the formation of air pockets. The formed air pockets thermally insulate a portion of the outer cup surface located directly behind the air pockets.

Abstract: A coffee server for serving brewed coffee is insulated with a partial vacuum pulled in a void (36) between the walls of an outer vessel (20) and an inner vessel (32). The outer and inner vessels are fabricated of metal and have a top narrow neck opening (22) and (34) that are attached together with a hermetic seal (42). The partial vacuum is for minimizing heat loss conducted through the combined vessels permitting coffee placed inside to retain its useable heat content for at least six hours without additional heat being added. A pour spout neck (44) is fitted to the vessel necks and provides a liquid flow path when the server is tilted to pour coffee that is stored inside. An offset brew though stopper (52) including a hinged cover (58), is removably attached to the pour spout neck with the cover pivoted to permit coffee from a brewer to enter the server through an offset portion of the stopper during the filling process.

Abstract: A fuel tank for a motor vehicle comprising a wall composed of two shells arranged one above the other. The outer shell of the wall preferably has an inlet orifice and an outlet orifice. A filter element is arranged in front of the outlet orifice. Scavenging air from the inlet orifice thereby passes first into a gap between the shells and subsequently to a filter element. As a result, fuel vapors can no longer diffuse through the wall and pollute the environment.

Abstract: The present invention is disclosed to provide a heat insulating container constructed to avoid the deterioration of an appearance or to prevent the noisy sound from occurring by the scraps generated in the course of welding. An inner casing is arranged in an outer casing so as to maintain a space therebetween, the inner casing and the outer casing being joined by welding and a scrap movement blocking member is provided at least one of the inner and outer casings for preventing the scraps generated in the process of welding moving into the space.

Abstract: A three-dimensional rotating cup includes an exterior fixed cup, an interior fixed cup and a middle rotating layer. The middle rotating layer is inside the exterior fixed cup. The interior fixed cup is inside the middle rotating layer and a transparent fluid is filled inside the clearance between the interior fixed cup and the exterior fixed cup. Furthermore, extending outwardly from the edge of the interior fixed cup is a protruding flange. The bottom of the protruding flange is joined to the top of the edge of the exterior fixed cup. The inside and outside walls of the exterior fixed cup and middle rotating layer and the outside wall of the interior fixed cup include figure paintings.
