The invention proposes a biological protection membrane which is mounted, in a device for dispensing liquid from a sterile packaging bottle, across a fluid-circulation duct, in the path of the liquid extracted from the bottle and the outside air which is drawn into the bottle. The membrane (7) is made partially of a hydrophilic material and partially of a hydrophobic material. Both the hydrophobic portion (23) and the hydrophilic portion (22) are made from a polymer base, laden in the body thereof with a biocidal agent that is active in the destruction of bacteria by the ionic oxidation effect. The circulation of fluids through the membrane (7) is organised so as to promote the ionic action on the flow of outside air in the hydrophobic material, and to drive the ionically charged active agent by the liquid passing through the membrane in the hydrophilic portion thereof. A porous buffer (8), inserted in the path of the fluids on the inside of the membrane, collects the active agent extracted from the membrane by the remaining liquid not dispensed, passing through the membrane from the outside towards the inside.

Provided are a tube container having a shutoff function on a shoulder and a neck and a method of manufacturing the same, in which a head gas barrier layer formed of an aluminum sheet is bonded to inner surfaces of the shoulder and the neck serving as a head to correspond to the inner surfaces according to formation of the head, and thus the shutoff function is provided to prevent chemical changes in even a shoulder and neck portion due to external environmental factors, so that contents filled in the tube container are prevented from decaying or deteriorating, and intrinsic ingredients of the contents are prevented from being lost for a long time. Accordingly, the contents are prevented from decaying or deteriorating due to the external environmental factors, and the intrinsic ingredients of the contents are used for a long time without losing the intrinsic ingredients.

A packaged product, a method of manufacturing a package, and a method of dispensing a consumable substance from a package. The packaged product may include a flexible tube having a cavity and an opening that forms a passageway into the cavity. A cap may be detachably coupled to the flexible tube to close the opening. A flexible container may be positioned within the cavity of the flexible tube, and a consumable substance may be disposed within the flexible container, which can be completely sealed and free of openings prior to first use. Introduction of one or more drops of water into the first cavity through the opening in the outer container may dissolve at least a portion of the flexible container thereby forming a hole in the flexible container through which the consumable substance is configured to be dispensed.

A fluid dispensing container is provided. The container includes a container body formed from a first flexible material defining an interior cavity. The container includes a membrane formed from a second flexible material and a seal coupling the membrane to the inner surface of the container body. The membrane divides the interior cavity into a contents chamber and a dispensing chamber, and the membrane and the seal are configured to be fluid tight to maintain fluid within the contents chamber prior to rupture of the membrane. The rupture stress of the second flexible material is less than the rupture stress of the first flexible material such that, as fluid pressure within the contents chamber increases, the membrane is configured to rupture without the container body rupturing.

There is provided a pack (10) in the form of a stirrer for a hot or cold beverage. The stirrer comprises first and second films (13, 14) sealingly connected around a periphery to enclose a volume in which is disposed a liquid. The liquid is conveniently disposed in an elongate channel (15) formed in one of the films. Openable portions (17, 55) are provided at respective ends of the stirrer, one openable portion (17) allowing the liquid to flow out once opened and the other openable portion (55) acting as a vent. Each openable portion is opened by peeling apart the two films and has a stronger connection (52, 57) provided to limit the opening of the ends.

There is provided a pack (10) for a product (12) which is sealingly retained in a volume defined by first and second films (13, 14) sealingly secured about a periphery. The pack has an openable portion through which a liquid contained in the product (12) can be dispensed. One of the films (14) has a pre-formed hinge (20) across at least part of the volume to assist folding of, and liquid extraction from, the product (12). The pre-formed hinge (20) may be in the form of a pre-formed fold line.
