Methods of manufacturing and fixtures for manufacturing containers, particularly for holding cosmetic products, using thin-walled tubes. One end of a container may be formed using an integral process, such as insert molding, while the other end of the container is formed using assembly steps, such as welding, to form a completed cosmetics container from a thin-walled tube.

A biodegradable sampling bag for containing samples or the like, comprises a flexible enclosure defining a chamber adapted to contain therein the sample, the flexible enclosure being made of a plastic material, which contains an additive that renders the flexible enclosure biodegradable when exposed for a sufficient period of time to microbial action. The additive is adapted to enable microorganisms to metabolize the molecular structure of said flexible enclosure. The additive is effective in altering the polymer chain of the plastic material to allow microbial action of a suitable environment to colonize in and around the plastic material, whereby microbes can then form a biofilm on a surface of the flexible enclosure and secrete acids which break down the entire polymer chain. The flexible enclosure, when exposed to microbial action, is adapted to withstand biodegradation for a given period of time, typically of at least three months.

A method of manufacturing a high pressure tank includes: preparing a liner; forming a fiber reinforced resin layer which is a layer of a fiber reinforced resin on an outer side of the liner, and forming a resin layer which is a layer formed of a portion of a thermosetting resin on an outer surface of the fiber reinforced resin layer; increasing a temperature of the fiber reinforced resin layer and the resin layer to a predetermined temperature which is a temperature at which the thermosetting resin is cured; causing a pressure in the liner to be regulated to be a second pressure higher than a first pressure which is a pressure in the liner in the forming of the fiber reinforced resin layer and the resin layer; and maintaining the temperature of the fiber reinforced resin layer and the resin layer at the predetermined temperature.

Upon manufacturing a heat-resistant container using PET sheet, high heat-resistance is achieved without a stretching operation. The method comprises a molding sheet-making process, wherein a sheet is made including organic acid metal salt particulates produced by allowing an inorganic basic material or carbonate that is solid at ordinary temperature to react with an organic acid that is solid at ordinary temperature in the equivalent relationship, and a container-molding process, wherein, the molding sheet made in the molding sheet-making process is heated to 80-130° C., formed into a container shape by a vacuum or vacuum-pressure forming machine using a mold, and heat-set by keeping at 130-220° C. in the same mold, and the container formed in the container-molding process has a crystallinity of 18% or more.

A plastic container for storing a product. The container includes a base formed of a plastic material and sidewalls formed of the plastic material and extending upwardly from the base, ending in an open top adapted to be closed by a cap, and with the base defining an interior volume. The container also includes a snapping frame integrally formed in the base of the plastic material. The frame has a convex base shape before activation when the pressure in the interior volume is less than or equal to a predetermined critical pressure and has a concave base shape immediately after activation when the pressure in the interior volume is greater than the predetermined critical pressure, thereby increasing the interior volume and avoiding catastrophic failure of the container. Also disclosed are a method of using the container and a process of manufacturing the container.

Container (1), obtained by blow molding or stretch blow molding of a blank made of plastic material, which comprises a body (2), a shoulder (3) in the extension of the body (2) at an upper end thereof, and a neck (4) in the extension of the shoulder (3), the shoulder (3) being articulated between two stable positions, namely a deployed position in which the shoulder (3) projects from the body (2), and a retracted position in which the shoulder (3) is at least partially retracted into the body (2), the shoulder (3) being articulated in order to be able to adopt, in addition to the deployed position and the retracted position, a third stable position, intermediate between the deployed position and the retracted position.

An air bag packaging arrangement and a self-adhesive checking valve, the air bag packaging arrangement includes an air bag and an air valve which is the self-adhesive checking valve. The air bag includes first and second cell overlapped layers to form an air chamber and a valve opening. The air valve includes first and second sealing films overlapped between the first and second cell layers, and a strengthening film provided between the first valve film and the first cell film to strengthen a joint strength between the first valve film and the first cell film, so as to prevent the first valve film from being broken, so as to further avoid an air leakage.

Method for producing tilled containers from parisons made from a thermoplastic material, wherein the respective parison is at least conditioned thermally and is subsequently shaped during a shaping and filling phase in a mold by the action of the pressure of the supplied filling substance into the respective container at a shaping and filling pressure, wherein, during the shaping and filling phase, the parison is guided at least temporarily through a stretching rod and/or is stretched in the axial direction, and wherein, at least at the end of the shaping and tilling phase, the respective container has an internal pressure which corresponds to the shaping and filling pressure (p2).

Container of a bag-in-container type, wherein a neck region of the container is provided with at least one opening extending substantially radially there through, into a space between the outer container and an inner container adjacent thereto, wherein the neck region is provided with coupling elements, preferably at opposite sides of the at least one opening, seen in circumferential direction, for coupling of a connecting device to the container for introducing a pressure fluid through the at least one opening into a space between the inner and outer container.

A method for producing an element of a capsule, the capsule being intended to contain a product having at least one component that can be extracted by means of an extraction fluid, comprises the step of obtaining at least one preparatory zone intended to define, during use of the capsule, a passage for the extraction fluid, so that the extraction fluid can pass through the capsule in order to extract said component. The preparatory zone is obtained by means of a cutting operation carried out before the capsule is filled with the product and after the capsule element has been formed. The cutting operation is carried out by means of a blade element.
