A flat strip 1, suitable for forming a tube flexible skirt, comprising a decorative film 15 superimposed on a primary film 16, said primary film 16 consisting of a series of polymeric layers and comprising a sealable inner layer 14 at the lower surface 20 of the strip 1, said decorative film 15 comprising a sealable outer layer 7 at the upper surface 19 of the strip 1 and a decorative layer 8, 9.

The primary film 16 comprises means for stabilizing the strip 1 and protecting the decorative layer 8, 9 against heating.

There is provided an apparatus 1 that includes a pair of molds 10a and 10b that press together, heat, and weld an overlapping part of a plurality of film-like members, a pair of heater blocks 20a and 20b that respectively support the pair of molds; a plurality of first support blocks 37 that are connected via a plurality of rod-like members 50, which midway include parts that restrict transmission of heat, to one heater block 20a; a plurality of second support blocks 38 that are connected via the plurality of rod-like members to the other heater block 20b; and a driving mechanism 60 that changes, via the support blocks, a gap between the pair of molds to press together the film-like members. The plurality of first support blocks include at least one movable support block 39 including a mechanism 35 that moves in a first direction relative to the driving mechanism corresponding to thermal deformation in the first direction of the heater block to be supported, and the plurality of second support blocks include at least one movable support block 39.

This method for producing a packaged food product portion includes the following steps: providing a cup defining an inner area for receiving the food product; cold pouring, at a temperature below 50° C., the food product into the receiving area of the cup; covering the food product using a thermally insulating lid arranged such that thermally conducting flaps of the cup extend toward the outside of the lid after the covering step; folding the flaps on an outer face of the lid opposite the receiving area; and heat-sealing the flaps on the outer face.

An applicator mitt assembly system comprises an applicator mitt tooling including: a tooling body having a mitt-perimeter cutter and weld bead thereon which are shaped to a perimeter of a mitt to be cut; a heating element associated with the tooling body which is shaped so as to substantially match a shape of the weld bead to create a perimeter weld for the mitt when engaged with the tooling body; and an ejector platen which is actuatable relative to the tooling body to eject a cut and welded mitt. A conveyor device is adapted to feed mitt material towards the tooling and a tooling actuator adapted to actuate the tooling relative to the conveyor device to allow the cutter to cut mitt material at the conveyor device. A discrete applicator mitt tooling, method of assembling an applicator mitt, and welded applicator mitt are also provided.

The vacuum sealer includes a base, a cover, a vacuuming device, at least a heating device, at least a heat-resistant element wrapping around the heating device, at least a heat insulation element between the base and the heating device, at least a power provision device, and at least a safety breaker device. The safety breaker device includes at least a safety switch, and at least a trigger element. The object to be sealed is placed on the heating device and, as the cover closes the base, the safety switch engages the trigger element to release the safety breaker device and to allow the power provision device to power the heating device. The heat insulation element prevents heat from being conducted to the base. With the dual protection from the safety breaker device and the heat insulation element, safety is enhanced and the power provision device may operate under high voltage.

A device for sealing sample tubes comprises a tool assembly configured to interface with a rack holding a plurality of sample storage tubes, the tool assembly holding a plurality of punches and a die plate including a plurality of cutting holes, with each of the plurality of cutting holes accepting one of the plurality of punches. The tool assembly receives a foil sheet between the punches and the die plate. The device includes an actuator enabling linear movement of the tool assembly. Linear movement of the tool assembly towards the rack engages the die plate against the rack and punches the punches through the cutting holes of the die plate to punch a plurality of sealing sections from the foil sheet and to press and seal each of the sealing sections against a top end of each of the plurality of sample storage tubes in the rack.
