A volumetric displacement preservation system for preserving a volume of flowable substance in a vessel. A fluid exchange structure has a stopper, a head portion, and a fluid exchange valve with a first condition where fluid inlet and exhaust pathways in the fluid exchange structure are simultaneously closed and a second condition where the fluid inlet and exhaust pathways are simultaneously opened by conduit joining portions in the fluid exchange valve. A chamber retains a volume of preservative gas and is connected to the fluid inlet pathway externally to the vessel. The preservative gas can be supplied from the chamber into the vessel through the fluid inlet pathway as liquid is exhausted through the fluid exhaust pathway. The chamber can be replenished from preservative gas displaced from the vessel in a reverse volumetric displacement process or from preservative gas supplied by a preservative gas production canister.

A sealing station for a packaging machine, the sealing station may be a tray sealer. The sealing station includes an upper die with a sealing plate and a lower die with a tray holder for receiving at least one packaging tray to be sealed. A cutting blade is arranged within the sealing station, and cuts a lid for closing the packaging tray out of a top film. The cutting blade has an endless cutting edge for cutting out the lid along its contour. The cutting blade includes a first and a second blade section, for cutting out a first and second section of the contour of the lid respectively. The second blade section may produce a tear-off corner in the lid projecting beyond the edge region. The sealing station may include a first clamping jaw on the sealing plate, and a second clamping jaw on the tray holder.

Storage containers and lids for such containers are provided. The lid has a first lid face and a second lid face. The second lid face has a rim configured to attach the lid to a storage bin. On the first lid face and extending to the second lid face is a plurality of apertures to provide airflow through the lid. A seal material extends from the second lid face that is configured to make the airflow path selectively sealable at a continuous wall and closed surface of a corresponding storage bin.

Thermoformed trays comprising ribs retain individual food products in place. The individual food products are generally elongate and prone to displacement during handling. The formed trays comprise: a base; a plurality of sidewalls integrally formed with and extending from the base, the base and sidewalls defining an interior cavity having a cavity width; a plurality of pairs of ribs integrally formed with and extending from first and second opposing sidewalls into the interior cavity, and a plurality of channels positioned between and separating adjacent ribs, wherein each channel of an adjacent pair of ribs defines an individual food product receiving slot. Each rib may extend into the interior cavity a length that is at least about 7% of the cavity width.

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.

A vessel cap (100, 10) for exchanging gas in and pressuring a vessel headspace (30), the cap (100, 10) comprising a cap inlet (11), a seal (12) arranged to form a gas-tight seal on a vessel opening, a pressure reducing valve, a gas inlet port (25) arranged to allow incoming gas into the vessel headspace (30), a gas outlet port (31) arranged to allow outgoing gas to escape from the vessel headspace (30).

A packaging system and methods for the preservation of volatile chemicals in a product containing volatile chemicals is disclosed. The packaging system generally has one compartment adapted for the storage of the volatiles containing product in communication with a second compartment which contains a source of volatile chemicals such that the volatile chemicals disperse into the first compartment. The make up of the volatile chemicals in the second compartment are selected either to match the naturally occurring volatile chemicals in the product to be packaged or to complement the naturally occurring volatile chemicals in the product to be packaged. In this way, the naturally occurring volatiles content of the product can be preserved or odors and flavors that do not naturally occur within the product can be added. In some case, the product to be packaged is cannabis.

The receptacle including stacking lugs to help reduce vacuum and friction when de-nesting the receptacles. The receptacle including a lid that helps when storing certain types of goods and/or serves as a seat. A septum or receptacle molded into the lid to allow for injection of inert gases or flushing headspace.

Disclosed are packaging systems and method useful in extending the storage-life of foodstuff such as fresh fish. The packaging systems and methods can be used to transport or store the foodstuff for an extended period of time. The packaging systems preferably use a fuel cell to maintain a reduced oxygen level in the environment surrounding the foodstuff.

The invention relates to a container for packaging products, in particular fresh products such as meat products. The container comprises a container body with a product space for accommodating a product and a receiving space at least for receiving liquid, preferably liquid from the product. The container body according to the invention comprises partition means that separate the product space and the receiving space from each other. The partition means comprise at least one outlet opening configured to at least discharge liquid from the product space to the receiving space. The container is further provided with at least one resistance element extending into the receiving space, which resistance element surrounds the outlet opening in such a manner that the resistance element prevents the transport of liquid from the receiving space to the product space.
