Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to the packaging of a sealer equipped with an evacuation and welding device used for packing foodstuffs in sealed bags.

Conventional technology Conventionally, as a sealer, the opening of a synthetic resin film package containing food or other packaged items is held between the main body of the sealer and a top cover that is swingably attached to the main body of the sealer, and the inside of the packaging bag is sealed. There is a known sealing device that evaporates the package with a vacuum nozzle, then squeezes the opening and welds it with a heater to seal the package.However, the inner surface of the package was simply flat. .

Problems to be Solved by the Invention However, in the conventional method, during the process of evacuating the inside of the packaging bag and welding the opening, the inner surfaces of the packaging may come into close contact with each other, or the packaging may come into contact with the object to be packaged. When the packaging bag is bent under the weight of 1000 yen, the inner surfaces of the packaging bag stick together, making it impossible to completely exhaust the air inside the packaging bag, resulting in the problem that the bag is welded together with the item to be packaged, with air remaining.

SUMMARY OF THE INVENTION An object of the present invention is to solve these inconveniences and provide a sealing device packaging that can reliably exhaust air from inside the packaging bag and weld the opening of the packaging bag.

Alternative Means for Solving the Problems In order to achieve the above-mentioned object, the present invention includes a sheet made of a nonwoven fabric with good air permeability laid on the inner surface of a synthetic resin film constituting the package.

Function: With this structure, when the air inside the wrapping bag is exhausted, even if the flat parts in the middle of the packaging come into close contact with each other, or the wrapping bends due to the weight of the packaged item, the wrapping bag will not close. Because the inner surface is covered with a sheet made of highly breathable non-woven fabric,
Even if the flat parts come into close contact with each other during the packaging, or even if the packaging is still bent, the air can be reliably exhausted through the air-permeable nonwoven fabric.

Embodiment One embodiment of the present invention will be explained with reference to the drawings. In Fig. 1, 1 is the main body of the sealer, 2 is an upper lid swingably attached to the main body 1 with a support shaft 3, and 4 is connected to a vacuum pump. It is a vacuum nozzle. This vacuum nozzle 4 is interposed between a convex bag holder 5 raised on the main body 1 and a urethane foam bag holder 6 of the upper lid 2, and the vacuum nozzle 4 is housed in a net-like nonwoven fabric 8' shown in FIG. When the package 8 is inserted into the opening 9 and the top lid 2 shown in FIG.
is closed with the upper and lower bag holders 5 and 6 except for the vacuum nozzle 40, and the push rod 13 of the top cover 2 presses the micro switch 12 attached to the main body 1 for operating the vacuum pump, energizing it, and the vacuum pump is activated. The air inside is exhausted by the vacuum nozzle 4. 14 is a heater placed on the main body 1 in front of the vacuum nozzle 4; 16 is an elastic heat sealing presser with a releasing tape 16 attached to the surface thereof, which is provided at a position facing the heater 14; and a heat sealing presser 15 The heater 14 is normally in a separated state, and when the presser piece 17 provided on the upper cover 2 so as to be able to swing back is pressed, the operation described later is performed, and the magnet piece 11 is moved by the magnet 1o to swing the upper cover 2 and the heater 14 and the heat seal presser foot 16 are brought into pressure contact with each other, and the push rod 19 of the top cover 2 presses the micro switch 1B attached to the main body 1 for stopping the vacuum pump operation and activating the heater, stopping the operation of the vacuum pump, and energizing the heater 14 to generate heat. Then, the opening 9 of the package 8 is welded. Next, when the set time required for welding has elapsed, the power is automatically turned off, and when you press the operation lever presser foot 1 of the top cover 2 again, the heater 14 and the heat seal presser foot 1
The pressure contact state with 6 is released and they separate, completing the seal puncture. Thereafter, during the above operation, even if the flat parts of the packaging come into close contact with each other while the air inside the packaging 8 is exhausted by the vacuum nozzle 5 and the vane 4, or due to the weight of the object to be packaged 7 in the packaging 8, the packaging 8 Even if the packaging is bent midway through, the ventilation can be carried out without any problem due to the highly breathable non-woven fabric laid on the inner surface of the packaging.

Effects of the Invention As described above, according to the present invention, even if the flat parts of the package come into close contact with each other or the package bends due to the weight of the packaged item, the air can be removed by the highly breathable nonwoven fabric laid on the inner surface of the wrapping bag. It has the effect of being exposed.
