A process and apparatus (1) for packaging a product (P) arranged on a tray (4) is disclosed. The apparatus comprises a packaging assembly (8) configured for tightly fixing one or more film sheets to one or more trays. The packaging assembly includes a lower tool (22) defining a prefixed number of seats (23) for receiving the trays and an upper tool (21) facing the lower tool and cooperating with the upper tool to define a packaging chamber (24). The packaging assembly (8) is configured to operate at least in a first operating condition, where said packaging chamber (24) is open, and in a second operating condition, where said packaging chamber (24) is hermetically closed. First injection apertures (90) are positioned in corner regions of the seat and are configured to inject streams of gas in a direction substantially parallel to and above the flange (4c) of a tray (4) positioned in said seat. The process includes the step of activating injection of a plurality of streams of gas through said first apertures (90) in order to form a controlled atmosphere inside the tray before closing the tray with the film.

Certain exemplary aspects of the present disclosure are directed towards a manufacturing apparatus including a first chamber having a first cavity, and a first actuator. The first actuator aligns the opening of the first chamber to an opening in a second chamber having a second cavity, sealing the first cavity to the second cavity. The manufacturing apparatus further includes gas flow componentry that in conjunction with the first actuator and first chamber evacuate the second cavity by drawing a vacuum in the first cavity. After the second cavity is evacuated, the gas flow componentry fills the second cavity filled with a gas by introducing the gas to the first cavity. A second actuator seals the gas in the second cavity by applying a seal that covers the opening in the second chamber while the first and second cavity remains sealed to one another via the first actuator.

The present application discloses a vacuum sealed container, including a container body, a container lid, a vacuum generator, at least one magnifier and an indicator. The container body includes a first wall and a bottom surface, wherein the first wall and the bottom surface define an accommodation space. The container lid is coupleable to the container body. The vacuum generator is coupled to the container lid to evacuate fluid from the accommodation space. The at least one magnifier is coupled to the container body. The indicator is coupled to the container. A method for using the aforementioned vacuum sealed container is also disclosed.

A tray for receiving sausages is provided. The tray includes cells which are adapted to substantially match the shape of sausages or other soft materials. The tray may be vacuum sealed to cause a relatively uniform top surface suitable for stacking. The tray may be sealed without pre-freezing the sausages and without causing significant deformation to said sausages upon thawing. The tray may be loaded in an automated manner without the use of robotic arms placing individual sausages into the tray.

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 process is disclosed for controlling a plurality of magnetrons of a thermal processing tunnel in accordance with a preconfigured magnetron actuation scheme. In some implementations, the process can include the steps of: receiving an identifier indicating a predefined packaged food product configuration; based on the identifier, obtaining a preconfigured magnetron actuation scheme that is preconfigured based on at least one characteristic of the predefined packaged food product configuration, wherein the preconfigured magnetron actuation scheme is preconfigured to cause at least one of the plurality of magnetrons to have a different execution characteristic than at least one other magnetron of the plurality of magnetrons; and transmitting at least one instruction in accordance with the preconfigured magnetron actuation scheme to a signal controller that drives the plurality of magnetrons, thereby causing the plurality of magnetrons to execute in accordance with the preconfigured magnetron actuation scheme.

The disclosure provides a smart heat sealing method for vacuum packaging, comprising steps of: recording a time interval ?t between two adjacent starts of a heating device which is continuously started a number of times; recording a number k of starts of the heating device; obtaining a first heating coefficient p.sub.1 based on ?t, obtaining a second heating coefficient p.sub.2 based on k, selecting the heating constant t depending on specified parameters and performance of the vacuum package machine, and calculating the heating time T for next operation of the heating device by a formula T=p.sub.1*p.sub.2*t based on p.sub.1, p.sub.2, and t. It solves the heat accumulation problem of the heating device caused by too much repeated use or overuse in short time interval, and thus avoids unsuccessful vacuuming and solves the problem of poor heat sealing effect, and greatly improves user experience.

A contact lens package may include a first package layer, a second package layer, a lens receiving area defined between the first and second package layers, a first seal portion between the first and second package layers extending around a first portion of the lens receiving area, a second seal portion between the first and second package layers extending around a second portion of the lens receiving area, and the second seal portion having different sealing properties than the first seal portion. The second seal portion together with the first seal portion complete a seal around the lens receiving area. The first seal portion defines an unsealed gap at a location around the lens receiving area, and the second seal portion closes the gap. The gap allows a flow of fluids after a formation of the first seal.

The present invention relates to a method of introducing nitrogen into a beverage container. The beverage container (10) comprises a cylindrical neck part (16) having a circumferential rim (18) defining an opening (20). The cylindrical neck part comprises an outer circumferential flange (22) encircling the cylindrical neck part. A connecting element (36) comprising a circular closure plate (64) and a cylindrical housing (54) having a set of inwardly oriented locking parts (56) is positioned such that the cylindrical housing is at least partially covering the cylindrical neck part and a fluid path (58) is defined between the connecting element and the cylindrical neck part. A collar (42, 44) comprising a gas inlet (48) is placed about the cylindrical neck part and gas is injected into the beverage container via the gas inlet. Finally, the connecting element is moved towards the cylindrical neck part for arresting the connecting element to the cylindrical neck part and sealing the circular closure plate against the circumferential rim.
