A sheet member container having one or more sheet members including a main-body forming sheet member in which a plurality of film layers including an inner film layer and an outer film layer are stacked; a containing portion that accommodates contents; a container main body including the main-body forming sheet member, and surrounding the containing portion; and a peripheral edge sealing portion in which the one or more sheet members are folded along a folding line, and peripheral edge portions of the one or more sheet members are attached to each other.

The disclosure provides ethylene/α-olefin copolymer based co-extruded, multi-layer films, including barrier films and non-barrier films, and articles of manufacture that include the films, such as flexible bags and containers for flowable materials. The films and articles that include the films have improved flex-crak reisstance and toughness. The films and articles that include the films have good barrier properties as the barrier films include a core layer of ethylene-vinyl alcohol (EVOH) copolymer having a high ethylene content. The low amount of EVOH copolymer in the total film that is needed to achieve the flex-crack resistance, toughness, and good barrier properties, further allow for the recycling of the films and articles of manufacture.

A cap assembly comprising a body, a sealing membrane and a retaining ring. An opening is provided through the body and includes a recessed circumferential channel and a membrane engaging flange positioned proximate the recessed circumferential channel. The sealing membrane covers the opening and includes a body engaging flange and a pierceable surface. The retaining ring is positioned with the sealing membrane engagement surface in overlying engagement with the sealing membrane. Extension of the tab into the recessed circumferential channel of the body releasably maintains the overlying engagement and biases the retaining ring against the membrane. The inner wall structure of the retaining ring extends radially inward beyond the membrane engaging flange of the sealing membrane, to, in turn, protect the membrane.

Non-durable self-supporting flexible containers having product volumes and structural support frames are provided with vents to facilitate equalization of the pressure inside the product volume to the pressure of the environment outside of the containers. The vents enable rapid recovery of the structural support from a deformed state, which occurs when a fluent product is dispensed, to an undeformed state. For this purpose, the vents comprise vent paths between the environment outside of the containers and the product volume. The vents may further comprise a non-wetting material surrounding the entrance and exit of the vent path and/or microtexturing or a spacer to maintain space for air flow in the vent path.

A sealing container is designed to enable a user to adjust the timing of discharging the contents. The sealing container includes: a bag-shaped member for accommodating the contents therein, a sealing film for sealing the bag-shaped member, an opening means so configured that at least a part of which is movable toward the sealing film and is capable of opening the sealing film, an operation unit for performing an operation of moving the opening means, and a discharge means configured to be capable of discharging the contents from the bag-shaped member at a timing different from a timing at which the opening means penetrates the sealing film by operating the operation unit. It is possible for the user to perform only the operation of opening the sealing film by operating the operation unit, so that the user is able to arbitrarily adjust the timing at which the content is discharged from the bag-shaped member of the sealing container.

The present invention refers to an automatic opening device for a package, the device comprising an spout, a cap and a means for tearing the sealing element of a package, which can be either the aluminium layer of an aseptic carton package, or a sealing element located under the spout or the plastic material of a plastic pouch or the like.

The present application relates to a system for dispensing fluid. The system includes a flexible container including a spout that is in fluid communication with an interior region of the container. The system includes a cap configured to be mounted to the spout. The cap includes an opening that leads to a membrane and a first retention mechanism located in the opening. The system includes a piercing tube having a first end configured to puncture the membrane and a second end configured to be connected to a dispensing tube. The piercing tube includes a seal bead and a second retention mechanism. The piercing tube is inserted into the opening of the cap such that the first end punctures the membrane, the first and second retention mechanisms engage each other to retain the piercing tube in the cap, and the seal bead sealingly engages the cap.

A pouch container has a gas filling space therein, and includes a first wall section and a second wall section. The first wall section includes a first tongue-shaped portion. The second wall section includes a second tongue-shaped portion and overlapping the first tongue-shaped portion. A projection length of the second tongue-shaped portion is longer than that of the first tongue-shaped portion. A gas injection portion is provided in which an injection port communicating with the gas filling space is formed by joining both end portions of both the first tongue-shaped portion and the second tongue-shaped portion in a width direction, and the injection port is defined by a tip end portion of the first tongue-shaped portion in a projection direction and the second tongue-shaped portion at a portion facing the tip end portion.

A barrier spout having a base flange and an upstand portion. The base flange has a top surface, a bottom surface and an outer surface. The upstand portion has a proximal end extending from the base flange terminating at a distal end. An upper opening is defined at the distal end, and a lower opening is defined at the proximal end. The base flange and the upstand portion each comprise a three layer co-molded configuration including an outer layer, an inner layer and a central layer. The central layer has an oxygen transmission rate that is less than an oxygen transmission rate of either of the outer layer and the inner layer.

An apparatus for material storage, transport and dispensation uses a bag constructed from one of more flexible plastic sheets and forming a chamber for holding material. Reinforced end regions of the bag may be removably coupled to one another to form a self-forming loop. A nozzle is coupled to the chamber by a flexible tube to form an attachment for dispensation of material from the chamber. The attachment may take the form of a shower head, for example.
