A method of preserving a liquid in a container comprises connecting a fluid flow line between a headspace of the container and a pressure modifying means and performing an operating cycle of the pressure modifying means during which the dynamic pressure in the fluid flow line is measured and compared to an initial target dynamic pressure value Pt. At the end of the operating cycle, a static pressure is measured in the fluid flow line and a pressure correction Pcorr is applied to the initial target dynamic pressure value to obtain an updated target dynamic pressure value Pt′ for use in a subsequent operating cycle of the pressure modifying means. The pressure modifying means may be a vacuum pump for the preservation of still wines, or a gas supply for the preservation of sparkling wines. A corresponding system is also disclosed.

A system and corresponding method for charging an aerosol can with a compressed gas charge includes a base that is adapted for receiving a can that (i) houses a product and (ii) includes a means for injecting gas, such as a grommet or valve on the bottom of the container, and includes a compressed gas source, such as a pre-charged canister of compressed air, and air compressor, and/or an automatic or manual air pump. The can may be filled with at atmospheric pressure and then shipped while the can contains approximately atmospheric pressure. Upon receipt of the can, a user may charge the can with a compressed gas and repeat charging if needed after some of the product has been dispensed.

The invention relates to a device for vacuum stoppering a medical container. The device includes a main body defining an internal volume that has a variable pressure chamber configured to be connected to a vacuum pump. A stopper holder system is arranged in communication with the variable pressure chamber and is configured to receive and hold a stopper aligned with the direction of travel of a piston rod. A piston rod is moveable inside the internal volume of the main body along a longitudinal axis between a proximal rest position and a distal operative position wherein the piston rod pushes the stopper into the medical container. A container holder system provided in the main body, is arranged distally relative to the stopper holder system and in communication with the variable pressure chamber.

Apparatus and Method for Manufacturing a Smoking Article Pack An apparatus (10) for manufacturing a sealed pack (20, 34, 36, 37) of smoking articles (2) and modifying an internal atmosphere thereof. The apparatus (10) comprises a handling mechanism (13) for conveying a sealed pack (20) of smoking articles (2) within the apparatus (10). The handling mechanism (13) includes a support plate (24) against which a pack (20) abuts during conveyance by the handling mechanism (13). The support plate (24) includes a gas port (29). The apparatus (10) is configured such that, as a pack (20) is conveyed by the handling mechanism (13) in abutment with the support plate (24), the gas port (29) may engage a valve (4) formed in the pack (20) to enable a gaseous atmosphere within the sealed (20) pack to be modified. Also, a method of manufacturing a pack (37) of smoking articles (2) by means of such an apparatus (10).

An electrical vacuum-pumping device includes a primary structure body, an upper lid, an electrical vacuum pump, a power source, and a suction nozzle. The primary structure body includes an upper body board and a lower body board which are fastened with each other, and in which an accommodating space is provided. The lower body board is provided with a suction hole for communicating with ambient atmosphere. The electrical vacuum pump is provided with a vacuum-pumping mouth, and is arranged in the accommodating space, and is electrically connected with the electrical vacuum pump. The suction nozzle is fixedly arranged underneath to the lower body board. When in a state of use, the suction nozzle can engage directly with an impermeable cup or a joint at one's option; or engage an object to be vacuum-pumped and then attach the same to the object to be vacuum-pumped.

A vacuum adapter device is useful for connecting a suction generating device to a garment bag. The device includes at least one conical section. The conical section includes a wide opening configured be connected to one of the suction generating device and the garment bag and a narrow opening connected to a reinforcing feature configured to prevent the narrow opening from collapsing when suction is applied to the device. The conical section is constructed with a flexible polymer material.

An evacuated bottle system including a bottle defining a hollow interior, the bottle having a neck with a rim defining an opening; a cap assembly supported on the bottle, the cap assembly including a funnel having a first portion and a second portion, the first portion being insertable within the interior of the bottle and the second portion engaging a portion of the bottle to support the funnel above the rim, the funnel defining a bore that fluidly communicates with the hollow interior of the bottle; a self-sealing membrane that covers the bore formed by the funnel to selectively seal the hollow interior of the bottle; a cap attachable to the bottle, the cap including a cover portion that extends at least partially over the self-sealing membrane to restrain movement thereof, the cover portion being axially spaced from the self-sealing membrane to define a gap that permits axial movement of the self-sealing membrane to selectively open the bottle to fluid communication outside of the bottle.
