A bag or liner can be sized to fit into a bucket, such as a five gallon bucket. The bag or liner can extend above the height of the bucket to form a funnel portion to assist in pouring material into the apparatus inside the bucket. The bag or liner can have graduations corresponding to volume of material poured into the bag or liner and bucket to assist in mixing ingredients of a material. The bag or liner can include a flat bottom wall and internal seams to conform to the bucket's shape. The bag or liner can include perforations to permit detachment of the funnel portion of the bag or liner. To enhance the preservation of mixed ingredients and the workability of the mixed ingredients, the bag or liner can include a re-sealable seam at a top opening of the funnel portion that permits evacuation of air enclosed by the bag or liner through a one-way valve that supports vacuum packaging. The bag or liner can include integral handles to allow easy removal of the bag or liner from the bucket.

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.

Stopper assembly for a serving device configured to be positioned in a neck of a container, such as a bottle, wherein the stopper assembly comprises a body element arranged to fit in the serving device; a valve element mountable on the body element, wherein the body element extends substantially in a direction transverse to the valve element; and a handling element that is connectable to the valve element and extending in a direction substantially transverse to the valve element at an opposite side of the body element, such that the valve element is arranged in between the handling element and the body element.

A laminated package for solid products in powder or grain form, includes a set of stiffening notches, a dispensing mouth with a seal, valves for loading inert gas, in which the lateral folds of the upper face are folded inwards under the front and rear flaps, and the lateral folds of the lower face are folded outward and folded and stuck on the lower face over the front and rear flaps, and a method for forming the package.

A cap apparatus includes a cap body and a valve body. The valve body includes an upper portion, a lower portion, and a stem intermediately disposed between the upper portion and the lower portion, the valve body including a bore formed therein having concentric alignment to and traversing the upper portion and the stem, and the valve body including a perforation formed therein having concentric alignment to and traversing the stem and the lower portion. The perforation forms a substantially impermeable seal within the valve body. The cap body includes an aperture in coaxial alignment with the bore and the perforation. The inner surface of the cap body includes multiple internal threads.

A resealable vacuum valve for sealing a canning jar has an annular vacuum interface ring, a vacuum interface ring surface, and a valve interface bottom surface opposite the vacuum interface ring surface. A sealing membrane is interior to the vacuum interface ring. An anchor stem is fixedly attached to and extending from the bottom of the sealing membrane. At least one air evacuation hole is disposed through the sealing membrane interior to and equidistantly around the interior of the vacuum interface ring. With the anchor stem of the vacuum valve extended through a hole disposed in a lid placed onto a canning jar, a vacuum is applied to the vacuum valve removing air from inside the canning jar through the air evacuation holes such that the vacuum seals the sealing membrane bottom surface to the canning jar lid while sealing the canning jar lid to the canning jar.

One embodiment of an apparatus with mobile reusable airtight container assembly (10) which utilizes pressurized inert gas or CO2 gas for long term preservation of the freshness of roasted coffee beans or grounds in terms of aroma and taste, utilizes a system of an electronic controller (250), pressure switch (170), gas delivery valve (180), check valve (50) and vent valve (160) to create a pressurized environment of inert gas or CO2 gas and low residual oxygen and moisture concentrations within the airtight container assembly (10). An airtight lid (20) with pressure seal (220) covers the airtight container assembly (10) and creates a reusable system whereby the user can remove a portion of the roasted coffee beans or grounds as often as needed in order to brew coffee without degrading the long term freshness of the roasted coffee beans or grounds stored within the airtight container assembly (10). A two stage opening mechanism (40) prevents uncontrolled opening of the airtight lid (20) while the airtight container assembly (10) is pressurized. The check valve (50) enables the mobile aspect whereby the airtight container assembly (10) can be removed from and replaced back on a control system (260) as many times as desired by the user, while maintaining the optimum storage condition of pressurized inert gas or CO2 gas with low residual oxygen and moisture concentrations.

A multi-chamber device is described. The device can include a first chamber and a second chamber disposed within the first chamber. Each chamber may be formed from a flexible material. A first tube may extend between the first chamber and outside the first chamber to enable addition of gas to the first chamber. A second tube may extend between the second chamber and outside the first chamber to enable removal of gas from the second chamber.
