摘要: Provided are a double container assembly comprising: a double container comprised of a relatively-rigid outer container and a flexible inner container disposed inside the outer container and capacity-variable in response to an amount of a content thereof, and capable of being easily produced using a molding apparatus which is not largely different from a conventional type; and a threaded cap, and a manufacturing method for the double container assembly, wherein the double container assembly and the manufacturing method can form an external air introducing opening in the double container significantly easily and reliably at a lower processing cost than that in conventional techniques. During the course of moving a pair of partial molds to come close to each other so as to combine them together to make up a split mold, a portion of a parison corresponding to a small-outer-diameter region of a double container is clamped by at least respective parts of mating surfaces of the pair of partial molds, to thereby form a protruding tub piece. Then, the protruding tub piece is cut off to form a space between the outer and inner containers of the double container, and an opening area of the space is sufficiently expanded through an operation of threadingly engaging the cap with the double container.

摘要: Provided is a double container which comprises a relatively rigid outer container and a flexible inner container disposed inside the outer container and capacity-variable in response to an amount of a content thereof. The double container is configured to contain, particularly, a high-viscosity liquid, e.g., a liquid having a viscosity of 1000 to 100,000 mPa/s, and to be easily produced by a forming technique having no significant difference from conventional techniques, wherein the double container for a high-viscosity liquid is capable of containing the content without causing oxidation thereof, while maintaining the outer container in its original shape or dimensions, and discharging the content by squeezing the outer container, irrespective of a level of a remaining amount of the content.

摘要: The present invention is a double-walled container manufacturing method in which when a pair of partial molds is brought towards each other to be assembled to form a split mold, at least a portion of the mating surfaces of the pair of partial molds clamp a parison at two side portions that are at horizontal positions facing each other. The method is able to manufacture the container easily with a molding device that does not differ significantly from the past and, in a double-walled container obtained from a relatively rigid outer container and a flexible inner container the volume of which can change according to the amount of contents filled inside said outer container, an opening for introducing outside air can be formed very easily and reliably at a lower cost than the processing cost of prior art.
