A needleless syringe connector cap to be provided to a container having an aperture at its top, said cap comprising an elastically deformable plastic valve body. Said valve body comprises a first and second passage, each passage extending through the valve body. Both passages comprise a cross-slit valve in the extreme lower end of said passage, embodied as an aeration valve. The first passage is adapted to receive a first tapered syringe tip and the second passage is adapted to receive a second tapered syringe tip, wherein when fluid is withdrawn from a container to which the cap is provided through the first (second) passage using a first (second) tapered syringe tip to which said first (second) passage is adapted, the second (first) cross-slit valve opens in response to an under pressure in said container resulting from said withdrawal, so as to aerate said container.

An assemble and disassemble structure for container liner and liner locking device thereof, which provides a drinking container having a mineral liner that can be replaced through the assemble and disassemble structure. The assembly is provided with an outer cylindrical sleeve, the interior of which is a holding space. The outer circumference of the upper end of the outer cylindrical sleeve is a connecting end, and the mineral liner is inserted into the outer cylindrical sleeve. A connecting ring is provided with a clasping portion, and assembling the clasping portion to the outer cylindrical sleeve enables fixing the mineral liner in a stable position in the outer cylindrical sleeve. An elastic locking device locks the connecting ring at combining angular positions.

A container has an at least partially filled container body and at least one cap part (10). The cap part has at least one sealing part (16) that, for removal of the container contents, can be penetrated by a hollow-spike-shaped insertion part (22) from the outside, with a predeterminable actuating force, in an introduction direction. The insertion part can be removed from the container again, with a predeterminable pull-out force, in an oppositely directed pull-out direction. A device (16, 18) makes it difficult for the insertion part (22) to be removed with the pull-out force being increased such that unintentional removal of the insertion part (22) is at least made difficult.

A sprayer system includes a sprayer head, at least two reservoirs, and a gripping portion. The reservoirs hold constituent components of a product. The product is emitted from a nozzle included in the sprayer head. The emission of the product results in the depletion of the components of one of the reservoirs to a greater extent than the remaining at least one reservoir and changes the center of gravity of the sprayer system.

A vial assembly may include a vial having a body to hold a liquid material, and a neck extending from the body. The neck may include a multi-use surface configured to permit access to the liquid material. The vial assembly may include a cap to be received by the neck and to cover the multi-use surface. The cap may include a base having a first major surface, and a second major surface opposite of the first major surface, arms extending from the second major surface, and a rupturable reservoir of disinfectant material carried by the base between the first major surface and the second major surface. One or more of the first major surface and the second major surface may be flexible so as to rupture the rupturable reservoir when the cap is received by the neck.

A device is described for facilitating the preparation of therapeutic foam e.g. for the treatment of varicose veins. A pressurised vial contains a sclerosant liquid, e.g., polidocanol solution, and a sterile gas which is readily absorbed by the body, e.g., carbon dioxide, oxygen or a mixture of these gases. The vial is provided either with a specialised stopper/seal into which a syringe nozzle may be inserted or alternatively a septum seal which may be penetrated by a hypodermic needle. The quantities of gas and liquid and the pressure in the vial are pre-set so that, on connection of a syringe to the vial, a predetermined volume of both gas and liquid is transferred to the syringe, with the intention that the syringe is then used to make a foam by known means. The use of the vial ensures that the ratio of gas to liquid in the foam is standardised, and also provides a convenient way of packaging the gas and liquid and of filling the syringe in a sterile manner.

A device for closing a chamber of a container having an opening for accessing the chamber comprises a plunger, a plunger seat, a container carrier and a spacer. The plunger seat releasably holds the plunger in a predefined alignment. The container carrier is arranged to be connected to the container in a predefined position and alignment in relation to the opening of the container. The spacer is arranged to position and align the plunger seat adjacent to and distant from the container carrier such that the opening of the container is open when the container is connected to the container carrier.

A method for manufacturing bubbles of the present invention includes: injecting an aqueous liquid 10 into a container 20 to a predetermined height; and vibrating the container at the number of revolution of equal to or high than 5,000 rpm such that the aqueous liquid 10 repeatedly collides with an inner surface of the container 20. According to the manufacturing, simply by vibrating the container 20 at a predetermined number of revolution, a large amount of bubbles 1 having a uniform size can be stably generated in the aqueous liquid 10. Furthermore, the vibrating the container 20 is preferably performed in a state where an internal pressure of the container 20 is higher than 1.0 atm.
