A piston for a reservoir of a dispenser of a fluid product without air intake, and presenting a central axis X includes both sealing means and also guiding means. The sealing means extend in a plane orthogonal to the axis X and define a single external sealing line in a closed loop, distal from the axis X, capable of coming into contact with an inner wall of the reservoir 10. The guiding means include a base from which extends one or more tabs with free ends defining external guide points, distal from the axis X, capable of coming into contact with the inner wall of the reservoir.

Apparatus (10) for the preparation of aerated drinks, comprising: an aerator stage (20) comprising: a removable aerator bottle (30) defining a chamber (32) for receiving a liquid to be aerated; an aerator bottle interface (40) operative to engage the removable aerator bottle (30) and seal the chamber (32) thereof; a gas inlet line (60) operative to fluidly connect a gas source (50) to the aerator bottle interface (40); and a gas supply mechanism (70) for controlling supply of gas from the gas source (50) to the aerator bottle interface (40) via the gas inlet line (60); characterised by: an aerated liquid dispenser outlet (110); a liquid outlet line (120) operative to fluidly connect the aerator bottle interface (40) to the aerated liquid dispenser outlet (110) to allow aerated liquid to flow from the chamber (32) of the removable aerator bottle (30) to the aerated liquid dispenser outlet (110); and a liquid flow controller (130) for controlling discharge of aerated liquid from the removable aerator bottle (30) to the aerated liquid dispenser outlet (110) via the liquid outlet line (120).

A dispensing pump mechanism is provided. The pump comprises integrally molded temper-evidence part between a container collar and a spout; said collar has multiple off-centre outlet channel for dispensing one or more products from the container; said collar also comprises an integrated air vent to be blocked and opened by the rotation of the spout. The whole pump can be over-molded one-piece structure with elastic parts as being actuating parts. The pump improves the functions of the pump, such as lower restitution rate, less structural parts, lower cost, water/dust proof, lightweight, easy assembly.

A piston for a collapsible cartridge for dispensing a material, the piston includes a rigid portion and a flexible portion. The rigid portion has a first diameter, a first end and a second end. The first end is configured to be disposed in a material dispensing direction. The flexible portion has a second diameter less than the first diameter, a first end disposed in the material dispensing direction and a second end disposed in an opposite direction. The flexible portion is disposed on the first end of the rigid portion such that the second end of the flexible portion is disposed to face the first end of the rigid portion. The flexible portion is configured to radially expand and longitudinally compress upon a force applied to the first end of the flexible portion to compress the collapsible cartridge between the flexible portion and an interior surface of a support cartridge.

A battery holder (10) comprising a translucent, extruded polypropylene body (11) having a rectangular passage (12) therethrough. The body (11) has an insertion end (13) and a remote ejection end (14). The battery holder body (11) has an elongate axis extending from the insertion end (13) to the remote end (14), and the axial passage (12) extends therethrough from the insertion end (13) to the remote end (14). The axial passage (12) is of substantially constant cross section transverse said axis, the cross section being selected to permit frictionally retarded movement of a battery (16) therethrough of from the insertion end (13) of the passage (12) to a remote ejection end (14). The axial passage is of a length selected to enclose a plurality of the batteries laid in series in an edge to edge manner.

A portable food carrier is disclosed, including a flexible, compressible outer container body and an internal lift having a tapered bottom. The tapered bottom of the lift is particularly configured to allow a user to grasp the carrier and squeeze the container body at the location of the taper, causing the lift to move upward in the container, in turn pushing food product located above the lift toward an open, top mouth of the container, where the user may then access and eat the food product. The lift is configured to interact with the interior of the container in such a way so as to assist the user in maintaining smooth movement as the user squeezes the outside of the container, thus making it optimized for use with only one hand.

A cosmetic container includes an outer container, an inner container inserted into the outer container to receive a content injected therein, and a pump support coupled to an upper opening of the inner container and including a support body connecting to an inside of the inner container. The container further includes a pump inserted through the support body to discharge the content, and a shoulder coupled to an upper portion of the outer container to downwardly press the pump support with respect to the outer container.

A content dispensing package apparatus is provided. The content dispensing package apparatus can be configured to elevate contents for immediate dispensing to the user, the user able to raise the contents from outside an outer container. For example, a container for dispensing edible contents can include a first container portion, a second container portion configured to move between a first position and a second position, and a tab coupled to the second container portion. The tab can be accessible from the outside of the container and used to move the second container.

Disclosed is a cosmetic container that allows easy recycling and refilling. A cosmetic container according to one aspect of the invention includes: an outer container; an inner container separably inserted into the outer container and configured to receive a content injected therein; a pump support coupled to an upper opening of the inner container and including a support body connecting to an inside of the inner container; a pump inserted through the support body and configured to discharge the content; and a shoulder separably coupled to an upper portion of the outer container to downwardly press the pump support with respect to the outer container, where separating the shoulder from the outer container may separate the pump from the support body and thereby enable a replacing of the inner container and the pump support.

A re-mixing dispenser for containing and dispensing a liquid. The dispenser may have one or more tubes, each containing a different liquid. At least one of the liquids may be re-mixed in situ, using a special two-piece plunger and plunger rod. A mixing piece of the two-piece plunger is moveable independently of a top piece and has blades that allow it to move through the liquid. A plunger rod is removably attached to the mixing piece and is operable to move the mixing piece up and down within the tube during mixing. The two plunger pieces are joined and moved as a single plunger during dispensing.
