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.

This sensor storage container comprises a bottomed cylindrical container body (1) having an opening in its top face, an opening/closing lid (2) provided to the opening of the container body (1) in an openable/closable manner, and an inner case (7) that is open at its top face and provided within the container body (1). The opening/closing lid (2) is linked to the container body (1) via a hinge portion (3), at the peripheral edge of the opening of the container body (1). The inner case (7) is linked on the hinge portion (3) side to the opening/closing lid (2).

The invention is drawn to a container comprising a bottom wall and at least one sidewall extending upwardly from the bottom wall. The sidewall terminates in an edge and has an inner and an outer surface. The bottom wall and the at least one sidewall form a container interior. A flexible bag having an open end is disposed within the interior of the container and over the top edge of the container. A slide ring extends at least partially circumferentially about the outer surface of the sidewall and is affixed to the open end of the bag and frictionally engaged with the outer surface of the sidewall.

The invention relates to a closure device comprising a closure wall having a communication conduit passing through it and intended to close the opening of a container of a product and a stopper movable in the duct. The stopper comprises a cavity open on one side of the wall, closed by a bottom and comprising at least one lateral opening. In the closed position, this bottom closes the conduit, and in the open position, the side opening(s) and said bottom exit the conduit, the conduit thus being open in fluid communication through the stopper. The invention also relates to a product refill comprising a container closed by this closure device. It also relates to a dispensing device comprising this refill and a dispensing head.

A product lifting device including a lifting platform, a cap assembly, and a plurality of lifting lines configured to connect the lifting platform to the cap assembly. The lifting platform is configured to fit within a container having a cap and an opening. The cap assembly has both a lifting ring and an adapter. The lifting ring is configured to fit over a bottom part of the adapter, which is configured to fit over the opening in the container. The top part of the adapter is configured to receive the container cap. The lifting lines extend upwardly from the lifting platform, through the bottom part of the adapter from inside to outside, and terminate at the lifting ring.

The present disclosure provides a contact lens package containing a contact lens in a compressed state. In one exemplary embodiment, the overall internal depth of the package is less than the natural sagittal depth of the contact lens. Different single-use contact lens package shapes and configurations may be used. In some embodiments, a spring disc is included in the packages to help present the contact lens to the user when the package is opened. The contact lens packages may be adhered or clipped to a card or other carrier sheet, and may be housed in a number of different secondary packages.

A coaster is structured to be coupled to a conventional cup, such as an iced beverage cup, using a conventional cup sleeve. The coaster includes a generally disk shaped base having an outer perimeter. Two or more elongate tethers extend outwardly from the outer perimeter of the base. The coaster assumes a combination-ready configuration with the two or more elongate tethers extending generally upright and outwardly to a same side of the base, in such a way that the coaster fits snugly within a conventional cup sleeve. In a final combination configuration with a cup sleeve, the coaster combines with the cup sleeve to create an insulating and water absorptive coaster and sleeve, frictionally and snugly coupled to the cup in a robust manner to make the coaster highly portable together with the cup and cup sleeve, and configured to collect condensation formed on the exterior surface of the cup.

The present disclosure provides cases comprising a lift mechanism, kits comprising a case and an instrument, and methods of using same.

The present invention discloses a container with synchronous rising and lowering functions, which is configured to contain an article. The container comprises: a box body, having a containing space therein; a cover unit, connecting one side thereof to one side of an upper edge of the box body; a lifting unit, locating in the containing space for being placed the article; and a connection unit, connecting the cover unit and the lifting unit, wherein when the cover unit is opened, the cover unit is linked with the connection unit to allow the connection unit to drive the lifting unit to rise synchronously, and when the cover unit is enclosed, the cover unit is linked with the connection unit to allow the connection unit to drive the lifting unit to lower synchronously.

A quantitative pressing structure is disclosed herein. It comprises a pressing structure; an assembling seat disposed on the pressing structure for assembling at an opening of a container; a piston tube disposed at a bottom of the assembling seat and comprising a piston having a piston rod accommodated therein; a lid disposed at a top of the piston tube and having an outer casing protruded thereon and correspondingly disposed on a periphery of the piston rod, wherein an upper end of the piston rod of the piston penetrates the lid; a pressing portion disposed at a top of the piston rod; and a plurality of limiting kits having different heights for limiting a pressing down degree of the pressing portion, wherein each of the plurality of limiting kits has a slot for assembling on the outer casing of the lid.
