A pressurized refill canister containing a composition including a propellant. The canister has an outlet valve having a stem biased to a closed position by a first resilient member. The stem has a maximum outer diameter of greater than 3 mm. At the outlet end of the stem, at least part of the wall of the stem extends inwardly from the outside diameter for at least 50% of the radius.

A blender jar assembly consisting of a blender jar, a cover and a vacuum pump is disclosed. The cover includes a cover body including a connection channel and a locking system formed on the cover body within the connection channel, and a sealing plug set detachably connected to the cover body and locked thereto by the locking system to cover the connection channel and having an air hole and an air valve adapted for blocking the air hole. Thus, the sealing plug set can be selectively mounted in the cover body, and the connection channel can be provided for accommodating a measuring cup or for the insertion of a stirring rod.

The device consists of two separate parts: a stationary unit (12) which contains a motor (16) and vacuum pump (14), and a mobile head (20) with a power-supply switch for the motor and an aspirating nozzle designed to fit over the valve (32) in the lid of an airtight container (28, 30). The mobile head connects to the stationary unit with two flexible coaxial spiral cords, consisting of a hose (22) linking the vacuum pump and aspirating nozzle, and a power cord (36) linking the switch to the electrical motor. Both lines can easily be stretched together from the storage position, in which the mobile head sits on the stationary unit, to active mode, in which the suction effect keeps the mobile head coupled to the container.

The present disclosure relates to methods of producing a packaging container for bulk solids. The packaging container has an inner compartment and a transport closure closing the inner compartment, the transport closure being provided with a pressure relief valve, the method includes the steps of forming a tubular container body having an upper body opening; presenting the container body to an upper body opening sealing station comprising a plunger piston comprising a bottom plate, the bottom plate having a through hole; closing the upper body opening by pressing the transport closure into the upper body opening such that a pressure above an ambient pressure is produced within the tubular container body, allowing gas to exit the valve and the valve to be pre-conditioned; and attaching the transport closure to the container body wall.

An appliance including a heating and circulating unit immersed in a pot for cooking food inside a cooking bag immersed in the water. A first recess is formed in a base for storing the heating and circulating unit. A second recess is formed in the base for storing the vacuum packaging unit. A third recess is formed in the base for holding a supply of cooking bags. Prior to cooking food is placed into the cooking bag and evacuated with the vacuum packaging unit. The vacuum packaging unit includes an electronic display and an electronic control panel. An electrical cable connects the vacuum packaging unit and the heating and the circulating unit. The heating and the circulating unit and the vacuum packaging unit are controlled from the electronic control panel and data related to the operation thereof is displayed on the electronic display.

The present invention relates to the use of vacuum packaging and vacuum packaging techniques. Embodiments of the present invention include bales and packages comprising a sealed chamber having an internal volume at a pressure less than ambient atmospheric pressure. In alternate embodiments of the present invention, the internal volume of the package comprises a bulk material, a bulk fiber material, fibers or fibrous materials. Also disclosed are methods for packaging, packaging systems and apparatus for packaging.

The present invention relates to a food container evacuation module (31) capable of enhanced performances in terms of attainable vacuum and also being portable and easy to use, to a food container evacuation system (300) comprising it and to food containers (33) apt to be used in such food container evacuation system (300).

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 device for the packaging of products, particularly of the food type, includes a container made of material that is flexible and substantially impermeable to gases and water vapor. The container forms inside it a compartment for accommodating products and is provided with at least one passage opening for the introduction and/or evacuation of the products into/from the compartment. At least one functional port can be closed hermetically and is associated with the container in fluid communication with the accommodation compartment. At least one monitoring port is associated with the container in fluid communication with the accommodation compartment, which is adapted to allow the passage of fluid at least from the inside of the compartment toward the outside. An assembly for detecting at least one chemical-physical parameter of the atmosphere is located within the accommodation compartment.

Described is a transportable system for conditioning used mattresses, including a container made of floppy material designed to contain an air-tight mattress and including a suction valve, said system also comprising a suction device.
