A system for evacuating and sealing containers filled with product, for example, food product, includes an enclosed, sealed housing wherein the pressure level and the atmospheric content can be controlled. A vacuum shroud is positioned in registry with a container entrance opening in the housing, the shroud connectible to a vacuum source and to a source of replaceable gas to replace the ambient air to be removed from the container. The shroud is advanceable to seal the container entrance opening and is retractable from the container entrance opening. A container transport system inserts the container through the housing entrance opening and into the shroud. Thereupon, a sealing system seals the housing from the ambient after the container has been inserted into the shroud. After the air in the container has been replaced with an inert gas and then the shroud retracted, a closure subsystem applies a cover to the evacuated container. Thereafter, an out feed subsystem removes the closed container from the housing while maintaining the atmospheric content and pressure level within the housing.

An inventive vacuum storage container for long term storage of perishable and non-perishable items, incorporating a pump, power supply, controller, sensor, top cover, expandable seal, pressure sensor and base plate. The controller activates the pump based on signals from the sensor to maintain a vacuum state within an interior vacuum chamber formed by the top cover, expandable seal, and base plate. The container is configured to effectively maintain vacuum pressure by activating a pump when the lack of vacuum pressure is indicated.

A fluid storage bag comprising a storage bag sealed to a collapsible quick filling and self-sealing fill tube. After partially filling the storage bag, through the fill tube, to a desired level with water or other liquid the storage bag is inverted, thereby collapsing and effectively sealing the fill tube against itself. After use, the storage bag may be re-filled, or recycled. In one example, a 4 inch wide fill tube extends at 6 inches into the storage bag, with the last 5 inches creating a funnel to a 2 inch bottom width. In other examples air or other gas may be introduced through the fill tube; and as the bag is pressurized, the fill tube collapses and seals so that the bag may serve as a flotation device, air mattress, pillow or other device.

A food package having a heat-sealed cover composed of a lower plastic film and an upper plastic film which is distinct and separate from the lower plastic film is disclosed. The upper and lower films are collapsible, i.e., they can be creased and crumpled into a ball without effort or folded as a tissue paper. The lower film and upper film are heat-sealed to each other at respective perimeter edges to define a closed, watertight internal housing filled with a modified atmosphere. A tray, configured to house the food product, is inserted in the closed internal housing but is not fixed to the upper or lower film. The food packaging described herein allows a substantial reduction of plastic compared to those currently on the market, while guaranteeing its mechanical rigidity, and the long-term quality of the product. A method for producing the packaging is also disclosed.

The present disclosure relates to a method for preventing or reducing cannabaceae biomass decomposition during storage by packaging an amount of the biomass in a flexible film of gas impervious material to provide a cannabaceae biomass package which is impermeable to gases.

A vacuum sealing machine capable of locking cover automatically having upper cover limiting mechanism includes an upper lid, a lower seat, and an evacuation tank. The upper lid is hinged to the lower seat. The evacuation tank is located at the front of the vacuum sealing machine, and includes a lid-locking mechanism and an upper lid-limiting mechanism. The lid-locking mechanism is installed on the upper lid or the lower seat, and is connected to the upper lid-limiting mechanism. The upper lid-limiting mechanism includes a limiting lock plate and a limiting buckle portion. The limiting lock plate movably installed on the upper lid is fitted with the buckle of the limiting buckle portion installed on the lower seat; alternatively, the limiting lock plate movably installed on the lower seat is fitted with the buckle of the limiting buckle portion installed on the upper lid.
