A multifunctional vacuum sealing machine which includes a shell, and a vacuumizing device and a sealing device which are arranged in the shell, wherein the sealing device includes a hot welding device; cross sealing can be performed at a connector position twice, thus forming a completely-closed sealing line; and during vacuumizing, while a bag to be vacuumized is clamped and sealed by an upper cavity and a lower cavity, the bag is punched by a cutter head in the upper cavity, the bag is vacuumized, a punching position is in a closed area surrounded by one sealing line with the adjacent first heating wires and the second heating wire or in a closed area surrounded by the first heating wires and the second heating wires, and after vacuumizing, an opening is sealed at an original position, so that it is guaranteed that air cannot enter the vacuumized bag during sealing.

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.

A rechargeable sealer with storage function includes a casing, an electric heating module, a circuit board, a supporting base, a press bar, a spring-back mechanism, and a sliding plate. The casing is provided with an accommodating chamber, in which are provided with a fore contact element and a rear contact element. A rechargeable battery is positioned in and between the fore contact element and the rear contact element. The circuit board, provided with an external slot, is disposed in the accommodating chamber, featured in charging the rechargeable battery. The press bar is provided with a sliding slot, and is pivotally connected with the pivoting shaft of the supporting base, served as a pressing structure corresponding to the casing.

System, assemblies, and methods for heat shrink sealing open-topped containers wherein the system includes a two-part housing or enclosure wherein a majority of a bulk roll of film material is accessible when the cover is open. The system preferably includes a movable feed roll to improve the efficiency associated with reloading operations. In a preferred aspect, the system includes a movable sealing unit that accommodates use of the lidding system with open ended containers having various sizes and shapes. In a more preferred aspect, the system includes an indicia generating device operable to label sealed containers and a knife that generates a perforation in the film during sealing operations.

A vacuum sealer includes: a housing comprising a vacuum chamber therein; a vacuum pump in fluid communication with the vacuum chamber; a sealing mechanism adjacent a periphery of the vacuum chamber; a valve positioned and configured to releasably seal the vacuum chamber, the valve movable between a first position, in which the valve forms a seal with the sealing chamber, and a second position, in which the valve does not form a seal with the sealing chamber; and a controller operatively connected with the vacuum pump, the sealing mechanism, and the valve. The controller is configured to move the valve from the first position to the second position during sealing.

A vacuum sealing machine capable of locking a cover automatically having an upper cover limiting mechanism, comprising: an upper cover (10), a lower base (20), and vacuumizing grooves. The upper cover (10) is hinged to the lower base (20), and the vacuumizing grooves are located at the front portion of the vacuum sealing machine. The vacuum sealing machine comprises a cover locking mechanism and an upper cover limiting mechanism. The cover locking mechanism is mounted on the upper cover (10) or the lower base (20); the cover locking mechanism is connected to the upper cover limiting mechanism; the upper cover limiting mechanism comprises a limiting lock plate (40) and a limiting portion (36); the limiting lock plate (40) movably mounted on the upper cover (10) is snap-fitted with the limiting portion (36) provided on the lower base (20), or the limiting lock plate (40) movably mounted on the lower base (20) is snap-fitted with the limiting portion (36) provided on the upper cover (10); and the limiting lock plate (40) and the limiting portion part (36) are snap-fitted to form a bag-entry gap having a set height between the limiting lock plate (40) and the limiting portion (36). The present vacuum sealing machine can automatically lock and open the cover, so that the entire vacuum sealing work can be automatically completed only by fixing a vacuum packaging bag with both hands and pressing a start button of the vacuum sealing machine. The use of the machine is simple and convenient.

A non-powered cooler system with an integrated powered vacuum sealer wherein the outer body may be made up of a hard casing of hard plastic material or soft waterproof material. A battery powered vacuum sealer for use in connection with the non-powered cooler or otherwise. The non-powered cooler having a supplemental compartment configured to hold a battery powered appliance, such as a vacuum sealer, or a volume of food.

A method and apparatus for sealing a plastic enclosure is provided. The apparatus includes a handle including elements pivotally coupled together at a first end. The apparatus also includes a pair of spaced apart heating elements positioned along an inner surface of an element and connected to a power source where a longitudinal axis of the heating elements is oriented parallel with a longitudinal axis of the element. Plastic material including first and second plastic layers is positioned at an interface between the second elements. Upon pivoting the first elements from an open position to a closed position the heating elements increase a temperature at the interface to melt the plastic material and form a pair of spaced apart seals between the first and second plastic layers.
