The present invention pertains in general to an apparatus and method for the modification of atmosphere in the packaging of perishable items, such as food items, for increased longevity. Embodiments include apparatus and methods which provide a customizable mix of gasses dependent upon the food being stored, and process for the monitoring of estimated pressurized gas canisters remaining within a vessel providing pressurized gasses.

Provided is an automatic air-extracting sealing box cover, comprising a bottom cover and a top cover that are mutually detachably connected, wherein the bottom cover and the bottom cover are connected to form a device chamber, and an automatic air extracting apparatus is mounted in the device chamber; the automatic air-extracting apparatus comprises a power source, a pressure sensor, an air pump, and a controller; the power source is connected to power source input ends of the pressure sensor, the air pump and the controller; an air extracting opening of the air pump and a probe of the pressure sensor project out of a lower surface of the bottom cover; an output end of the pressure sensor is connected to a collection circuit, and an output end of the collection circuit is connected to an input end of the controller; a control signal output end of the controller is connected an on/off control end of the air pump.

A method of making a pack for food comprising the following steps. Forming a tray by providing a tray laminate comprising a fibrous web (21) bonded to a web of a gas barrier film (20) comprising a multi-layer laminate comprising a heat sealable layer and a gas barrier layer. Vacuum and/or thermoforming the laminate to create a tray with an upstanding rim. Filling the tray with a food product (F). Providing a web of lid film (13), the lid film (13) being a gas barrier film comprising a multi-layer laminate comprising a heat sealable layer and a gas barrier layer. Heat sealing the lid film (13) to the gas barrier film of the tray around the periphery of the tray to create a hermetic seal between the two barrier films. Severing the pack from the webs of material.

A closure for a container. The closure includes a carbon dioxide emitter, and a release rate control layer that is configured to control release of carbon dioxide from the carbon dioxide emitter into the container when the closure is coupled to the container.

A method for transporting a cassette pod for containing semiconductor waters is provided. The method includes transporting a cassette pod configured to receive a semiconductor wafer with a transporting apparatus. The method further includes supplying a gas from a cylinder into a housing of the cassette pod. The cylinder is externally positioned on the housing. The method also includes detecting a gas pressure in the cylinder with a detection element. In addition, the method includes issuing a signal to the transporting apparatus when the gas pressure in the cylinder is lower than a predetermined limit.

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 container for a consumable recipient product. The container also contains a non-consumable donor product carrier which contains a donor product which emits a substance to impart a characteristic to the recipient product in the container. The donor product carrier includes a barrier layer, disposed between the donor product and the recipient product, through which the substance can travel.

Inhibiting spoilage of items is achieved by providing a container having an environmentally controlled storage compartment sealed form the external atmosphere and a reaction medium in a separate compartment in fluid communication with the storage compartment.

The invention relates to a vegetable box which is capable of preserving the products in the box in a fresh state and for an extended period of time by exchanging the air composition inside the box via the respiration and photosynthesis of the fresh fruits/vegetables, and thus ensuring the oxygen and/or carbon dioxide to reach the target partial pressure and stabilizing the same at these values. The invention is characterized by comprising a lock sensor (6) which is arranged in the internal portion of the body (1) at the section where the body (1) contacts with the cover (2) and which senses the opening/closing of the cover (2); a gas sensor (7) which is disposed inside the body (1) and which measures the partial pressure of the oxygen and/or carbon dioxide gases inside said body (1), and then informs the control unit (9) of the obtained pressure values; and an electronic control unit (9) which, using the information from the lock sensor (1) and gas sensor (7), activates/deactivates the lighting unit (8) and which is disposed in the body (1).

An automatic replenishing system for automatically replenishing preservative gas within a compressible bladder for supply to the inner volume of a vessel. A compressible bladder has an outer wall and an inner volume. A supply conduit receives preservative gas from a source, and a discharge conduit supplies preservative gas to a vessel. An inflation detection system detect a first condition wherein the compressible bladder is inflated to a state of inflation and a second condition wherein the compressible bladder is inflated below the state of inflation. A valve system is operative to prevent preservative gas from flowing from the source of preservative gas and into the compressible bladder when the compressible bladder is in the first condition and to permit preservative gas to flow from the source of preservative gas and into the compressible bladder when the compressible bladder is in the second condition.
