A low-temperature vacuum cooking device and a cooking appliance including low-temperature vacuum cooking device are provided. The cooking appliance may include a housing including a container mount and a vacuum-packing module mount provided adjacent to each other, a first container having a space to accommodate a liquid therein, the first container being configured to be coupled with the container mount, a heater that heats the liquid accommodated in the first container, a vacuum pressure generator installed on the vacuum-packing module mount to suction air inside a food packing bag, a sealer installed adjacent to the vacuum pressure generator that heats the food packing bag in order to seal it, a cover rotatably installed on the housing to cover or open the first container and the vacuum pressure generator, and a high-temperature cooking unit including a top plate and a high-temperature heater provided at a lower portion of the top plate.

A storage electric sealer comprises a casing, a sealing module, a spring switch, a support cover, a press bar, and a sliding plate. The casing and the sealing module are arranged on the casing. The support cover includes at least two containing grooves. The press bar provided with a sliding chute is pivotally connected with the pivoting holder of the casing. The sliding plate is provided with a heat insulation block and at least a stopper, both lateral side of the sliding plate being connected with the sliding chute of the press bar in a sliding manner. Wherein, the sliding plate is located at a closed position in storage state, so that the stopper is accommodated in the containing groove of the support cover. As such, the storage electric sealer can be transformed into a storage state by a modified sliding mechanism to reduce the volume and damage rate effectively.

A low-temperature vacuum cooking device and a cooking appliance including low-temperature vacuum cooking device are provided. The cooking appliance may include a housing including a container mount, a first container having a space to accommodate a liquid therein, the first container being configured to be coupled with the container mount, a heater that heats the liquid accommodated in the first container, a cover rotatably installed on the housing to cover or open the first container.

The present invention relates to a container, a method and a system for sterilising a medical device. The invention is particularly, although not exclusively, for use with orthopaedic medical devices, such as surgical instruments used in orthopaedic surgical procedures.

Disclosed is a tray sealing apparatus for sealing a disposable tray with a thermoplastic sealing film. The tray sealing apparatus includes: a base body having a top surface and a tray reception cavity formed in the upper surface; and a heater unit for heating the sealing film that the sealing film adheres by fusion to the flange of the tray inserted in the tray reception cavity. The heater unit includes a principal surface with a predetermined width, and a thin strip-type electric heating element formed in a closed curve shape corresponding to the shape of the flange of the tray. When sealing the tray with the seal film by fusion, the peripheral surface of the electric heating element is disposed along the whole flange of the tray with the seal film being interposed therebetween so as to apply the heat generated by the electric heating element to the seal film.

A machine is described for covering book covers and sealing envelopes or articles of various kind. The machine comprises a fixed lower base suitable for resting a sheet of flexible plastic material for an article to be covered, an upper part movable towards said base and a heatable blade accommodated in the upper part to execute soldering of the overlapped ends of the plastic material sheet along the article edges when the upper part is approached to the lower base. The machine comprises an electric motor, a control member accessible from the outside of the machine for operating the electric motor and movement transmission means acting on the sides of the upper part to induce, at every activation of the electric motor, movement of the upper part towards the lower base for executing the soldering of the ends of the plastic material sheet.

A combination chamber and external suction vacuum packaging machine is operable to evacuate a vacuum bag and seal closed an open margin of the bag. The vacuum packaging machine includes a base and a lid that define a vacuum chamber operable for use in a chamber packaging operation, where the bag is entirely received within the vacuum chamber, and an external packaging operation, where only part of the bag is received within the vacuum chamber.
