A set of preforms to make a container for beverages, comprising an external preform and an internal preform, each intended to form respectively an external keg and an internal bag of the container. The internal preform is associated internally with the external preform in order to define with the external preform a hollow space. The external preform and the internal preform have respective coupling members suitable to clamp the external preform and the internal preform with respect to each other in a desired reciprocal position.

To provide a container including an inner container that is deformed as content decreases, the container being a dispensing container reusable and excellent in an aroma retaining property. To implement such container, a dispensing container (10) includes a container body (13) including a flexible inner container configured to be filled with content and to deflate as the content decreases, and an outer container encompassing the inner container and having an intake hole through which external air is taken into a space between the inner container and the outer container, a discharge cap (15) including a top surface part having a discharge port through which the content is discharged, the discharge cap (15) being mounted on a mouth portion (13a) of the container body (13), and an external air introduction hole that provides communication between the outside and the intake hole. The inner container and the outer container are made of a polyethylene terephthalate resin.

The present invention is a double-walled container manufacturing method in which when a pair of partial molds is brought towards each other to be assembled to form a split mold, at least a portion of the mating surfaces of the pair of partial molds clamp a parison at two side portions that are at horizontal positions facing each other. The method is able to manufacture the container easily with a molding device that does not differ significantly from the past and, in a double-walled container obtained from a relatively rigid outer container and a flexible inner container the volume of which can change according to the amount of contents filled inside said outer container, an opening for introducing outside air can be formed very easily and reliably at a lower cost than the processing cost of prior art.

A method and apparatus of making an aerosol container. A polymeric container may be provided. The container may have a closed end bottom and a neck longitudinally opposed to the closed end bottom. The container has an internal container volume. A valve and a bag may be provided and a portion of the valve and the bag may be disposed within the container. The bag has a first bag volume. A portion of the at least one of the neck and the bag may contact a portion of the valve to form a temporary seal. Propellant may be introduced into the container. The bag may be collapsed from the first bag volume to a second bag volume. The pressure of the propellant and the pressure within the bag equilibrate. The valve may be joined to the container and the propellant may be sealed within the container.

A Propellant-Free continuous dispenser for dispensing liquid or viscous materials under pressure. The container comprises a tension surface, and a bag containing the liquid to be dispensed, which is in contact with the tension surface. An actuatable valve to which the bag is open serves to controllably release the liquid from the bag, and a diaphragm forms a floor to the tension surface underneath the bag. The diaphragm is elasticated and presses the bag against the tension surface to flatten the bag, thus to expel the contents under pressure.

The present disclosure relates to a container device capable of storing and discharging liquid.

A container device according to the present disclosure includes a pouch having the elastic property; a rigid container having a rigid outer case compared to the pouch and having a container opening at one side thereof; a coupling unit coupled to the container opening and for coupling an opening of the pouch with the container opening; and an air passage formed at the rigid container or the coupling unit. When the pressure is applied to the inside of the pouch and the volume of the pouch is increased, the volume of a space between the pouch and the rigid container is reduced by an increase in the volume of the pouch, such that the air in the space is discharged to the outside of the rigid container through the air passage to perform the depressurization of the space.

A delaminatable container excellent in productivity is provided. The present invention provides a delaminatable container comprising a container body having an outer shell and an inner bag, the inner bag to be shrunk with a decrease in contents, wherein the container body includes a storage portion to store the contents and a bottom seal protrusion protruding from a bottom surface of the storage portion, the container body is configured to seal the outer shell and the inner bag in the bottom seal protrusion, and the bottom seal protrusion includes a tapered portion extending in a longitudinal direction of the bottom seal protrusion and tapered from the bottom surface toward an end.

The present disclosure provides a container and a process for producing the container. In an embodiment, the process includes placing a sleeve bag on valve assembly (SBoV) in a blow mold apparatus. The blow mold apparatus has two opposing and movable molds. The SBoV has a valve seat. The process includes extending a parison of flowable polymeric material around the SBoV and between the opposing molds. The process includes moving the opposing molds to a closed position and pressing an upstream portion of the parison against the valve seat. The process includes blow molding a downstream portion of the parison into a container-shape within the closed mold. The process includes forming a container with the valve seat melt bonded to a neck portion of the container.

A method of manufacturing a delaminatable container is provided that is capable of uniformly delaminating the inner bag from the outer shell. According to the first aspect, a container body is formed having an outer shell and an inner bag. The inner bag preliminary delaminated from the outer shell in an entire circumference of a storage portion of the container body by rotating the container body while pressing the storage portion with a pressing mechanism from outside for compression or by moving the pressing mechanism along an outer circumference of the container body.

The present disclosure provides a flexible container. In an embodiment, the flexible container includes (A) four panels, each panel formed from a flexible multilayer film. The flexible multilayer film is composed of one or more polymeric materials. The four panels form (i) a body, and (ii) a neck. The flexible container includes (B) a fitment. The fitment includes a top portion and a base. The base is composed of a polymeric material. The base is sealed in the neck. The flexible container includes (C) a sleeve and bag-on-valve assembly, or SBoV. The SBoV includes a valve seat, a bladder, and an elastic sleeve. (D) The bladder and the elastic sleeve are inserted through the fitment and are located in the body. (E) The valve seat is attached to the fitment.
