Abstract: A beverage container configured from a front and a rear surface portion, a base portion, and a pair of gusset portions. The gusset portions configure side portions of the container by being sealed to mutually confronting edge portions of the front and rear surface portions and the base portion. The upper portions of the front and rear surface portions configure a neck portion that has a more slender shape than the remainder of the front and rear surface portions and that extends in a single direction. A notch is formed in the edge sealed portion of the neck portion. The front and rear surface portions are sealed directly together at a predetermined region corresponding to the notch without the gusset portions existing therebetween. A straw extends from and is positioned within the neck portion. The neck portion can be opened from the notch.

Abstract: A multilayer sheet harmless to human beings, having a certain gas-barrier property, and comprising an easily-produced metal film layer and a packaging material made of the multilayer sheet. The multilayer sheet is composed of at least a resin film layer and a metal film layer of magnesium or a magnesium alloy integrally formed on the resin film layer by evaporation, electron beam, or sputtering. Magnesium is harmless to human beings, and therefore such a multilayer sheet can be preferably used as a material of a food or medicine bag.

Abstract: A beverage container is configured from a front surface portion (5), a rear surface portion (6), a base portion, and a pair of gusset portions (7). The gusset portions (7) configure side portions of the container by heat sealed to mutually confronting edge portions of the front surface portion, the rear surface portion, and the base portion. The upper portions of the front surface portion and the rear surface portion configure a neck portion that has a more slender shape than the remainder of the front surface portion and the rear surface portion and that extends in a single direction. A notch (12) is formed in the edge sealed portion of the neck portion. The front surface portion and the rear surface portion are heat sealed directly together at a predetermined region corresponding to the notch without the gusset portions existing therebetween. A straw extends from the neck portion toward the base portion. The upper portion of the straw is positioned within the neck portion.

Abstract: A cartridge for a fluid dispensing apparatus, comprises a film shell having a tubular shape; and a film bottom member. The film bottom member is provided at the rear end of the film shell in the longitudinal direction thereof. The film bottom member is capable of being folded into a V-shape along a folding line or of being unfolded so as to expand at the central portion of the folding line in the transverse direction of the film shell, by filling the cartridge with fluid material.

Abstract: The present invention provides a gusset bag in which a sufficient area for indication can be retained on flat surfaces, paying attention to the structure of the gusset bag. The gusset bag 1 of the invention comprises flat surfaces 2 and 2 opposed to each other; and side surfaces 3 and 3 capable of being tucked in at creases by connecting the both ends of the flat surfaces 2 and 2; wherein a part of the side surfaces 3 and 3 is made transparent to form windows 9 and 9. Since windows 9 and 9 are provided on the side surfaces 3 and 3, it is possible to retain a sufficient area for indication in the flat surfaces 2 and 2, and observe the contents from outside.

Abstract: A self-standing container comprises a tubular main body and a bottom-forming sheet. The main body has upper and lower end portions, which are opened.

Abstract: A liquid container having a stable shape that is easy to fill and that enables the user to pour out liquid to the last drop into an intended target using one hand only and without spilling the liquid. An internal space of a container is defined by a front surface portion, a rear surface portion having the shape identical with the front surface portion, and a pair of gussets each connecting together each confronting edges of the front and rear surface portions. The gusset has a folded arrangement. If liquid is filled in the container, V-shape of the gusset expands to provide a three dimensional container. The gussets extend to a neck portion. By the expansion of the gussets, a spout has a sufficient open area capable of controlled pouring of the liquid therethrough. If the liquid amount in the container is reduced, the spout is automatically closed when the container is self-standing on a table.
