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.

A portable sanitizer dispenser including a body that securely encloses a bottle of sanitizer, an attachment mechanism operatively attached to the body, and a dispensing mechanism operatively attached at a mouth of the bottle or at a bottom of the body. A method of using the portable sanitizer dispenser, by attaching the portable sanitizer dispenser to an object with an attachment mechanism operatively attached to a body, actuating a dispensing mechanism operatively attached to the body, and dispensing sanitizer.

A method of manufacturing a container includes: a container preparing step of placing a filling space of the pouch inside a receiving space of an outer container; and a pouch expanding step of supplying air to the filling space of the pouch and expanding the pouch toward the receiving space.

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.

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.

A refill package for liquid products, comprising: (a) a rigid outer container comprising an inside face, an opening, and an air intake means; wherein the opening comprises a removable closure and wherein the air intake means comprises a sealable orifice and a sealing mechanism, and (b) a flexible inner body, for containing a liquid product; wherein the flexible inner body is joined to the rigid outer container around the opening.

A constant pressure system includes a pressure vessel with a vapor-liquid mixture used to provide pressure forces instead of compressed air that is typically used. The vapor-liquid mixture can be a number of substances, such as nitrous oxide, so long as the mixture exists in both the liquid and vapor phases. Importantly, the vapor-liquid mixture must maintain a constant pressure during the dispensing of fluids from the tank, so that the fluids are dispensed at the same constant pressure. As a result, the fluids within the tank can be dispensed at the same pressure as that of the vapor-liquid mixture within the tank, or scaled to a higher or lower pressure value through the use of a pressure-converter valve within the system.

A device for dispensing a material under pressure comprises one or more elastic portions defining a chamber within which the material is to be contained, and one or more non-elastic portions that are coupled to the elastic portion(s). The device optionally and preferably also includes an outlet for dispensing the material out of the chamber. When the material is contained within the chamber, the elastic portion(s) is stretched to apply inwardly directed compressive forces and urge a reduction in a volume of the chamber.

Elastomeric composites comprising natural rubber, a filler and nanofiller, which exhibit improved performance are disclosed. The elastomeric composite comprise a filler in an amount of less than 50 parts, yet exhibit high elastic modulus, high elasticity and reduced relaxation and/or creep. Articles and devices for dispensing fluid materials and comprising elastomeric composites are also disclosed.

A fluid dispensing mechanism for a fluid dispensing device, comprising an elastic sleeve surrounding a bag for filling with fluid for dispensing, the bag having a circumference and being folded at a plurality of folding locations around said circumference, thereby to unfold evenly under said sleeve during a filling process of pressurized filling of said bag with fluid, the mechanism further comprising an anchoring column. The bag is folded around the anchoring column.
