The object of this invention is to provide a delaminated bottle, which has a base cup fitted tightly around the bottom cylinder of the container and in which a slit is opened easily for the introduction of outside air into the interspace between the outer layer and the inner layer. The container has a male screw on the outer wall of container bottom cylinder and the base cup has a female screw, which is disposed in the upper portion of the inner surface of cylindrical cup wall and is screwed on the container bottom cylinder. The base cup has also an upright pushing section disposed in the lower portion of the inner surface of the cylindrical cup wall, and this upright pushing section pushes up on the walled bottom plate so as to open a slit in the outer layer of the pinch-off portion when the base cup is engaged with the male screw. Thus, the upright pushing section pushes up on the underside of the walled bottom plate at the time when the base cup is firmly fitted around the container bottom cylinder. The bottom seal is deformed and curved to open a slit easily and reliably so that outside air is introduced into the interspace between the outer layer and the inner layer.

L'invention concerne les emballages distributeurs pour produits visqueux, crémeux ou en pâte, ainsi qu'une méthode de fabrication pour ces emballages distributeurs. Le corps (6) de l'emballage suivant l'invention, en substance tubulaire, comporte une enveloppe intérieure (8), apte à contenir le produit à distribuer, et une enveloppe extérieure (7) capable de céder à la pression et de reprendre ensuite, en substance, sa forme initiale. Le corps (6) comporte une couche externe (40) sans discontinuité, en forme de manchon, une couche médiane (39) et une couche interne (81), réalisées à partir d'au moins une feuille de matériau enroulée sur elle-même à l'intérieur de la couche interne. Le corps tubulaire (6) ainsi formé est ensuite soudé, par une de ses extrémités, à une tête (1) distributrice, l'autre extrémité étant fermée par une soudure ou placée sur une embase. L'emballage suivant l'invention s'applique notamment aux produits cosmétiques, aux produits d'hygiène et à des produits techniques.

A package comprising, an elongated collapsible tube (14) defining a chamber to receive a flowable material, with the tube having a tapered shoulder (20), and a hollow neck (22) having an inner end extending from the shoulder, and an outer end. The shoulder normally causes flavor loss of the material in the region of the chamber adjacent the shoulder. The package has an insert (28) comprising a tubular section (30) having an outer end connected to the neck, and an inner end extending into the chamber a sufficient distance to prevent extrusion of the material in the region of the shoulder through the neck.
摘要:
A container (1) for liquid is described, comprising a base (2), a lid (3), a jacket (4) and an inner bag (5). The jacket extends (4) between the base (2) and the lid (3), defining with them a closed inner volume. The inner bag (5) is interchangeably positioned in the inner volume and can be filled with a liquid. In the filled configuration, the inner bag (5) holds upright the container; in the emptied configuration the inner (5) bag is bent on itself and the container is collapsed with the lid (3) close to the base (2) or in abutment thereon. The jacket (4) is a tubular member made of a laminar material that can be bent on itself like a textile, for example a band that can be bent like bellows. This feature allows switching easily from the upright configuration to the collapsed or bent one, without the need—as in solutions of the known art—to overturn rigid parts, disassemble envelopes or guide the rings defining the metal meshes.
