Provided is a wine stopper capable of being vacuumized, the wine stopper comprising a base capable of covering an outer side of a wine bottle, and a shell enclosing a cavity with the base. A boss capable of being clamped in a bottle opening is arranged on one side, away from the shell, of the base. The wine stopper further comprises a power source arranged in the cavity and a vacuum pump capable of creating a vacuum in the wine bottle, a through hole capable of communicating the vacuum pump with the interior of the bottle is provided in the boss, a measurement assembly capable of measuring a vacuum degree of the interior of the wine bottle is arranged in the cavity, and the measurement assembly is electrically connected with the vacuum pump.

Method for packaging electrical insulators (4) for high voltage or very high voltage, such as electrical line insulators made with a dielectric material chosen from glass or porcelain, and more specifically, electrical insulators with a protective hydrophobic silicone elastomer coating covering the surface of the electrical insulators, under vacuum or under inert gas.

Desiccant bag for electronic devices characterized in that it comprises: A first outer bag, made of plastic, hermetically sealed. A second porous bag, housed inside the first bag, leaving a gap between the first bag and the second porous bag, in which an absorbent material or drying product (superabsorbent polymer) is housed. A third porous bag housed inside the second bag, impregnated with an oxygen scavenger material housing the electronic device to be recovered and/or protected wherein the first two bags are crossed by a transverse pipe which has a connection having a bypass which starting from the connection penetrates inside the third bag. A minimization of the drying time, effectiveness in the process by using mechanical and chemical means and effectiveness that can reach 100% are achieved.

The sealing device includes a bag conveying mechanism, a sealing module, and a module conveying mechanism. The sealing module includes a base and an actuator, and a first sealing block and a second sealing block arranged on the base. The actuator is configured to open and close the clamping opening and includes a push rod and a horizontal actuation track. When the sealing module is moved along the conveying path of the module conveying mechanism, the horizontal guide post slides along the horizontal actuation track, and the horizontal actuation track drives the push rod via the horizontal guide post to move horizontally. Thus, the clamping opening is opened or closed.

The disclosure refers to a packaging device for manufacturing a packaging for a foodstuff. In particular, the packaging may include a trough-shaped lower packaging part and a top film which can be sealed together along their edges by means of a sealing tool of the packaging device. In order to improve a packaging device completely without evacuation or by evacuation in a simple and inexpensive manner with only a slight negative pressure in such a way that sufficient vapor purging is possible and at the same time cooling of the foodstuff before sealing or excessive degassing of the foodstuff does not take place, vapor can be introduced under pressure between the lower packaging part and the top film at at least one vapor entry point before sealing and can be released into the surrounding atmosphere at an outlet point from the packaging.

A method of making a pressurized packaged liquid beverage. The method includes filling a container including a one-way valve with a liquid beverage, sealing the container, introducing a volume of gas through the one-way valve after sealing the container, and agitating the liquid beverage inside the sealed container, When the container is opened, the liquid beverage increases in volume and separates into liquid phase and a drinkable foam phase. The method may be carried out in a sealed container including a one-way valve adapted to allow a gas to enter the first container but not exit or a circulatory agitation system according to other embodiments. Thee liquid beverage may include milk, coffee, fruit juice, or mixtures thereof, particularly mixtures of milk and coffee, and may further include a gum. The gas may be nitrous oxide.
