A bag-in-bottle type of a squeeze dispenser comprising a housing, a cap, a flexible bag for containing fluid, and means to equilibrate atmospheric air pressure with air pressure inside the housing is disclosed. Said means include a closable air channel. The closable air channel, and the cap, may each be in an open or a closed position. When the cap is in an open position, the closable air channel is in a closed position, thus substantially locking the air inside the housing in place and allowing for fluid to be dispensed from the flexible bag upon application of pressing force on the sidewalls of the housing. When the cap is in a closed position, the closable air channel is in an open position, allowing for a flow of atmospheric air into, and out of, the dispenser housing and thereby equilibrating the air pressure inside the housing with air pressure of the atmospheric air.

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 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.

Fluid supply systems for storage and dispensing of chemical reagents and compositions, e.g., high purity liquid reagents and chemical mechanical polishing compositions used to manufacture microelectronic device products, having capability for detection of an empty or near-empty condition when the contained liquid is at or approaching depletion during dispensing operation. Fluid delivery systems employing empty detect arrangements are described, including pressure transducer monitoring of dispensed material intermediate the supply package and a servo-hydraulic dispense pump, or monitoring of dispenser chamber replenishment times in a dispenser being replenished on a cyclic schedule to flow material from the dispenser to a downstream tool utilizing the dispensed material.

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.

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 manufacturing method of double walled container comprises preparing a parison having a rigid outer layer and a flexible inner layer, enclosing the parison within a mold including split mold halves, thereby forming a molded parison including a pre-blow cylindrical section, a pre-blow conical bottom section, a pre-blow bottom projection, and a lower parison excessive burr, blowing gas into an inside of the molded parison, thereby forming a blown parison including a cylindrical section and a bottom section, the bottom section including a bottom projection, and removing the lower parison excessive burr from the blown parison, wherein the flexible inner layer is fixed to the rigid outer layer in the bottom projection.

The present disclosure provides a dispenser for pressurized material. In an embodiment, the dispenser for pressurized material includes a container half having an exposed edge and a closure member at the exposed edge. The container half has a cup half in an interior top portion. The dispenser includes a reciprocal container half having a reciprocal exposed edge and a reciprocal closure member at the reciprocal exposed edge. The reciprocal container half has a reciprocal cup half in an interior top portion. The closure member and the reciprocal closure member matingly engage along the exposed edges to attach the container half to the reciprocal container half and form a container. The dispenser includes a sleeve bag on valve (SBoV) assembly in an interior of the container. The SBoV assembly includes a valve seat. The cup and the reciprocal cup support the valve seat to secure the SBoV assembly in the container.

There is provided a liquid supply apparatus eliminating the need for a power supply, having relatively light weight and small footprint, and ensuring a stable liquid supply. The liquid supply apparatus includes a first support member, a second support member, a balloon having one end supported by the first support member and the other end supported by the second support member, and a casing having a constant longitudinal length. The balloon is disposed in the casing and is configured so as to be able to hold a liquid therein and discharge the liquid therefrom. When the balloon holds the liquid, the one end and the other end of the balloon are positioned in the case.

The present disclosure relates to a pouch assembly for storing a liquid and a container device using the same. A pouch assembly according to an embodiment of the present disclosure includes a pouch unit which is formed of an elastic material and in which a charging space for charging the liquid is formed. The pouch unit includes a pouch unit body in which the charging space and a pouch-side opening communicating with the charging space on one side thereof are formed, a pouch-side catch which is formed on one side of the pouch unit body and in which an outer circumferential side thereof in a state in which the pouch-side catch surrounds the pouch-side opening further extends outward from an outer surface side of the pouch unit body, and a selective sealing unit which is disposed at an upper side of the pouch-side catch and selectively opens/closes the pouch-side opening.
