Abstract: A method for forming an overmolded container by covering a hollow inner bottle made of resin with an injection of a molten resin which forms an outer. The method comprises steps of setting the inner bottle in a mold with a space therebetween for forming the outer and circulating a pressurized gas into and out of a hollow space of the inner bottle through an upper opening thereof. The pressurized gas is supplied through a first path which opens toward an inner wall of the inner bottle and discharged out of the inner bottle through a second path. The pressurized gas supplied into and discharged out of the inner bottle is adjusted in pressure while the molten resin is being injected to the mold.

Abstract: [Object] To provide a parison for forming a container that includes a bottom of a thickness greater than that of a storage portion which has a squeezable property and to provide a blow-molding method using the parison. [Solution] A parison 50 is provided by injection molding in which external shapes of a neck forming portion 51 and a bottom forming portion 52 have the same external shapes as a neck section 20 and a bottom section 15 of a container 1 to be blow molded, respectively, and a body forming portion between the both forming portions has a thickness smaller than that of the bottom forming portion.

Abstract: A multilayered cosmetic container including a hollow inner container including a neck portion, a body portion with a diameter larger than that of the neck portion, and a shoulder portion, which connects the body portion to the neck portion, and a transparent outer layer over-molded on an outer side of the hollow inner container except a part of the neck portion, in which a curvature radius of a shoulder tip, which connects the shoulder portion to the body portion of the hollow inner container, is smaller than the curvature radius of the shoulder tip of the outer layer, which covers the shoulder tip of the hollow inner container, and centers of the curvature radii of the shoulder tip of the hollow inner container and of the shoulder tip of the outer layer do not conform to each other.

Abstract: A tube container has an outer tube formed with an extruding mouth at one end and two inner tubes each formed with an extruding mouth at one end. The inner tubes are inserted into the outer tube, and the extruding mouths of the two inner tubes are secured to the extruding mouth of the outer tube, respectively, while the other ends of the two inner tubes and the other end of the outer tube are pressed and welded together to form a hermetically sealed portion. The outer tube has a transverse cross section taking the form of an ellipse or a closed running track shape, namely a shape combining two semicircles with two straight lines. The inner tubes are arranged in the outer tube in the direction of major axis of the transverse cross section of the outer tube.

Abstract: This invention relates to a multi-tube container having multiple tubes in parallel. The container includes a plurality of body portions, each of which having a hollow portion for containing contents, a plurality of twistable head portions formed at one end of each of the body portions, a plurality of neck portions, each of which can be broken off by twisting of the head portion, creating an opening for extruding the contents from the hollow portion and is located between the body portion and the head portion, and a plurality of sealing portions formed at the other end of each of said body portions. Each of the sealing portions are breakably connected to the adjacent sealing portions, and at least one of the head portions and the neck portions are breakably connected to each other.

Abstract: A tube includes inner and outer sleeves that can be sealed simultaneously. The inner sleeve is supported in the outer sleeve stably while deformation of the inner sleeve is allowed due to discharge of contents therein. The outer sleeve encloses the inner sleeve to define a space therebetween. A dispenser for discharging the contents out of the inner sleeve includes a cylinder through which the contents is delivered. The dispenser is mounted to the outer sleeve and the cylinder is slidably related to the inner sleeve. Bottom ends of the inner sleeve and the outer sleeve are adhered to each other to define a bottom portion of the inner sleeve. The outer sleeve has at least one passage communicating the space with the outside of the outer sleeve.

Abstract: A tube container of double or triple sleeve structure is fabricated to include a molded nozzle having a neck and a shoulder formed integrally. An outer sleeve is welded to the shoulder of the molded nozzle An inner sleeve also is welded to the molded nozzle. A mixing nozzle piece is fitted tightly to the internal circumferential surface of the molded nozzle. A first creamy content is filled into the internal lower space of the inner sleeve and a second creamy content is filled into the annular space between the inner and outer sleeves.

Abstract: A vanity case includes a cover and a receptacle openably hinged together and formed of synthetic resin by molding. Provided on the outer surface of each of the cover and receptacle is at least one ornamental metallic band. Each band is integrally attached to the cover or receptacle by insert molding, with side portions of each band bent or folded downwardly to form generally a U-shape in section. The side portions are embedded in the synthetic resin forming the cover and receptacle, with the outer surfaces of the central portions thereof being exposed to extend outwardly from the surfaces of the cover and receptacle.

Abstract: A tubular container comprises a hollow body opened at one end and having in cross section a polygonal shape with sharp ridges being formed at corners, and a headpiece including a neck and a shoulder which includes an inclined portion having ridges and a polygonal configuration corresponding to the hollow body, the headpiece and the hollow body being integrally fused with each other with the ridges of the inclined portion being in agreement with the sharp ridges of the hollow body.

Abstract: A tubular container is molded with a cap by defining; at least one portion of a cavity for molding a neck portion between a female die for receiving a cap having a screw on the inside thereof and a male die having a fixed guide rod for insertion into the cap centrally thereof. A top end portion of a preformed container body is partly inserted into the cavity. A synthetic resin, which possesses compatibility with the container body and is not fused together with the cap, is injected into the cavity to form the neck portion integrally with the container body.

Abstract: A synthetic-resin-made container having ornamentation is formed by forming a flexible and ornamented tubular member and inserting it into an outer sleeve, disposing the sleeve in a molding die to define an annular space inside the tubular member, and injecting molten resin into the space and then solidifying the resin to form an inner sleeve which is fused with the outer sleeve at both ends thereof, thereby hermetically sealing the tubular member therebetween.
