A housing (1, 1′) for a pressurized container, has a bottom (12, 12′) a stopper, sealing means (124, 124′) to ensure sealing between the stopper (2, 2′) and the housing (1, 1′) when the housing is provided with a stopper; and retaining means (126, 126′) to retain, when the container is pressurized, a stopper (2, 2′) closing the opening. The retaining means (126, 126′) are distinct from the stopper (2) and are in an inactive initial form (125, 126) and must, in order to fulfill their function, be activated (126, 126′) after the opening has been closed by a stopper.

A laminate sheet, particularly an aluminium-based laminate comprises polyethylene having a density of 0.90-0.96 g/cc, a polyethylene-based film having a melting temperature of less than 240° C.; low density polyethylene in order to provide high adhesion; an aluminium barrier film, and a polyethylene-based film having a sealing property. Furthermore, the laminate sheet may further comprise a blown film or a dry laminate for making a tube and a tube shoulder in order to prevent flavor loss of the products packaged therein and without stress crack.

The present invention relates to metalworking, in particular to producing vessels from non-heat-treatable aluminium alloys used for tanks and pressure vessels. Disclosed is a method of manufacturing a vessel, the method including: forming a tube by rolling at least one flat blank and abutting the edges thereof, friction stir welding the abutted edges and working at least a part of the welded tube into a shape of the vessel, wherein the flat blank is a sheet of a non-heat-treatable aluminium alloy preliminarily subjected to cold working with permanent deformation within the range of 0.5-15%, and said working of at least one part of the welded tube is hot working at a temperature of 230-520° C. The technical effect is a reduction in vessel weight, an increase in vessel strength, a uniform vessel strength and a reduction in the number of hot working cycles during manufacturing of the vessel. Further, the method provides reduced metal and time consumption in manufacturing a vessel from a non-heat-treatable aluminium alloy, low payload ratio, increased reliability and longer service life of the vessel produced using the method.

A method for receiving and ejecting molded articles includes: (a) drawing air from a cooling tube cavity into an air channel through a plate bore to draw at least a portion of a molded article into the cavity; (b) moving a valve within the plate bore from a first position for conducting air from the cavity to the air channel to a second position for reducing air flow through the plate bore relative to the first position; and (c) when the valve is in the second position, urging pressurized air from the air channel to the cavity through the plate bore to assist ejection of the molded article from the cavity.

The invention refers to a method of manufacturing a pressure tank, comprising an inner container and an outer layer made of a fiber material which is wound around the inner container. In performing the method, a retention device with several retention elements protruding therefrom is attached to an inner container so as to wind a local pole cap reinforcement in a dome-shaped pole cap portion of the inner container. Then the retention device is removed and an outer layer is produced by winding of fiber material, the outer layer surrounding the central portion and the pole cap portions of the inner container.

A support includes a central portion configured to receive one or more products, a perimeter band which completely surrounds the central portion, a projection defined at the perimeter band and exhibiting at least one raised portion emerging with respect to the perimeter band and extended away from the central portion. The raised portion includes a through channel crossing the projection and having an access opening which is completely extended at a position spaced from the perimeter band and is configured to enable gas to pass into the through channel through the projection. The central portion and the perimeter band are made of sheet material.

Medicated starch-based powder formulations are packaged to ensure the medication remains stable for a desired shelf life. The medicated starch-based powder formulation may be packaged in a sealed container so as to maintain medicament functionality for at least one year. The container may be fabricated and/or lined with a low permeability coefficient and sealed with a foil heat induction seal liner. The container may be treated with a media to alter the surface properties of the container to increase the integrity of the container. The medicated starch-based powder formulation may include cornstarch and menthol.

Biodegradable insulating structures and panel systems, and methods for producing and assembling the biodegradable insulating structures are provided. The biodegradable insulating structures include biodegradable foam panels formed from biobased polymer foam beads which include polylactic acid. The biodegradable foam panels have edges that form a seal with adjacent biodegradable foam panels to restrict thermal energy transfer at the edges.

A virtually seamless, flexible, and shape-retaining bag and a method of manufacturing such a bag is disclosed. The bag is formed from two complementary three-dimensional custom shaped halves of molded flexible foam. A single and continuous piece of material, fabric, or textile is bonded or otherwise joined over the exterior of each half. The entire outer material covering each half is free of seams, stitching, or other joining of two separate pieces material. The complementary and exposed edges of the two halves are joined about a hinge and fastener, whereby opening the fastener allows the two halves to separate about the hinge, and closing the fastener secures the first half to the complementary second half of the bag.

A cultivation bag assembly for the cultivation of microbes, fungi and other organisms includes an inner bag for containing a food substrate and an organism to be cultivated. At least one wall of the inner bag is constructed of a layer of water-vapor permeable material. An outer bag of the assembly has first and second walls formed from gas impermeable layers. At least one of the first and second walls of the outer bag has a gas filter patch to allow the passage of oxygen and carbon dioxide gases into and out of the interior of the inner bag to facilitate incubation of the organism within the interior of the inner bag. The inner bag and outer bag are coupled together at a first end of each of the inner bag and outer bag.
