A device for treating hollow bodies, comprising at least a nozzle and a circuit for setting a pressurized airflow in circulation, having a valve and a first pressure sensor measuring a first pressure; a control distributor of said valve; a line connecting said distributor to said valve; a control unit with a time measurement component; wherein said device comprises a second pressure sensor situated along said line, measuring a second pressure, and wherein said control unit comprises means that are able to determine a differential between the measurement of the first pressure and the measurement of the second pressure as a function of time. The invention also relates to a corresponding treatment method.

A container with a shell and lining within its interior is provided. The shell and/or lining can be fabricated from a biodegradable, recyclable, and/or compostable material. The lining can be configured as a parison, a preform, and/or other mass that is capable of being expanded. The lining can be inserted within a cavity of the shell and caused to expand to form an expanded state. The lining, in the expanded state, may be used as a barrier, preventing beverage that is inserted into the container from making contact with the shell. The lining, in the expanded state, may be configured to maintain contact with an inner surface of the shell so as to provide adequate shock absorption. The lining can be a thin film, providing an overall thinner construction and/or an overall lighter construction can be used to fabricate the container.

To suppress the degradation of sealing property of a pressure vessel and the deterioration of a sealing member, and to reduce the workload and cost of manufacture, a blow molding device includes a pair of molds configured to be clamped to sandwich a parison from both lateral sides, and a blow pin configured to form a neck portion together with the molds. The blow pin includes a blow pin body portion having an outer circumferential surface of a shape corresponding to an inner circumferential surface of the neck portion, and a ring portion forming an annular recess portion between the blow pin body portion and the ring portion to form an outer circumferential surface of a tip portion of the neck portion, which is a smooth surface without any parting line.

Disclosed are a water storage tank bladder, a manufacturing method therefor, the water storage tank including the bladder, and a water treatment apparatus including the water storage tank. According to one embodiment of the present invention, the water storage tank bladder used in the water storage tank to receive and store water and discharge the stored water has a lower side of which the thickness can be thicker than the thickness of the upper side of the bladder and thicker than the thickness of the lateral sides of the bladder.

A system, that includes a container, that includes a first container opening, a liner disposed in the first container opening, a pump connected to the container, and a controller, where the controller is programmed to perform a method for filling the container with the liner, that includes making a first determination that a power on condition is satisfied, in response to the first determination, providing power to the pump, and after providing the power to the pump, making a second determination that a power off condition is satisfied, and in response to the second determination, cutting the power to the pump.

Multi-barrier bottles having tabbed preforms, as well as methods of forming the same are disclosed. A tabbed preform includes an elongate body extending into a cavity of a first barrier, where the cavity is defined by at least one piece having a recess therein. The tabbed preform further includes at least one preform extension piece extending from the elongate body at a predetermined distance from a top surface of the elongate body. The at least one preform extension piece is sized and shaped to correspond to a size and a shape of the recess.

A container including a longitudinal overlapping seam extending from an end seam and a mold part line extending from the closed end of the container to the open end of the container. The container wall consists of a one-piece thermoplastic substrate.

The invention relates to a blow-molded recipient including a reservoir, the reservoir having a bottom wall including an opening, a central element arranged at the opening of the reservoir, and a socket arranged to surround the central element. Both the socket and the central element show a lower end and an upper end and are connected by their respective upper ends by a disc with a central aperture. The assembly includes the socket, the central element and the disc, forming a ring that comes into one piece. At least a part of the bottom wall of the reservoir is arranged to face the disc. The reservoir is irreversibly fixed to the ring.

The present invention relates to a method for providing a product viewing window in a container. The container has at least a body ply and a liner ply, wherein the body ply has at least one aperture therethrough. The liner ply is adhered across the aperture, forming a window into the container. A window-finishing machine that comprises at least two platens and, optionally, a machine pocket positioned between them, a heating element extending through at least one of the platens, and a pressurized air device engages a container. The heating element heats the window of the container to the desired temperature, pressurized air is injected into the container such that the window is forced at least partially through the aperture of the container (and optionally into contact with the machine pocket wall), and the container window is then cooled to the desired temperature.

The present disclosure is directed to embodiments of catheter-based prosthetic heart valves. In one embodiment, a prosthetic heart valve includes a collapsible and expandable annular frame, a leaflet assembly mounted within the annular frame, a first skirt mounted on the frame, and a second skirt mounted on the frame. The frame includes a plurality of rows of cells. The leaflet assembly includes a plurality of leaflets. Adjacent leaflets are connected to each other to form commissures, each of which is connected to a cell of an outflow row of cells of the frame. Inflow end portions of the leaflets are sutured to an outflow end portion of the first skirt along undulating suture line.
