The bag supporting jig 9 is freely slidable and is pulled in backward like a nozzle immediately before sealing. Thus it does not interfere with the sealing permitting the mouth of the bag to be sealed easily and securely.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a hermetic packaging device used for packaging clothing used in general households.

2. Description of the Related Art Conventionally, this type of sealed packaging device generally has a structure shown in FIG. 5, and this structure will be explained based on the drawing. 13
is an article to be packaged, such as clothing, which is stored in the packaging bag 14. 15 is a sealed packaging device body (hereinafter simply referred to as the main body);
Reference numeral 15a denotes a main body base constituting this main body 15, and has a built-in air pump (not shown). 15b is a main body lid part. Reference numeral 16a designates a lower pressing portion provided on the main body base 15a, and reference numeral 16b represents an upper pressing portion provided on the main body lid portion 15b facing the lower pressing portion 16a. The lower pressing portion 16a and the upper pressing portion 16b are made of an elastic material and have the function of pressing the opening of the packaging bag 14 with good airtightness. Reference numeral 17a denotes a heat section provided on the main body base 15a inside the lower pressing section 16a, in which a heater for heat sealing is embedded. 17b is a heat pressing device provided on the main body lid portion 15b facing the heating portion 17a. The heat pressing device 17b is movable up and down, and normally remains in the upper position, but during sealing, it is pushed downward to press the opening of the packaging bag 14 into the heating section 1.
It is constructed so that it can be firmly pressed against 7a to seal it. A nozzle 18 has one end connected to an air bomb (not shown), and is provided at the center of the main body base 15a. 19 is a slide device connected to this nozzle 18 and slidable back and forth. The slide device 19 is used when setting the packaging bag 14 and when the packaging bag 14 is set.
When you inhale the air inside, it is pulled towards you. That is, the nozzle 18 crosses the lower pressing part 16a and the heating part 17a to a position where it abuts them. When this suction is finished, the nozzle 18 is drawn in from the front to the rear using the elastic force of a spring (not shown).

Reference numeral 20 denotes a fixture provided at opposing positions of the main body base 15a and the main body cover 15b, which engage and fix the main body base 15a and the main body cover 15b so that they do not open when they are closed. It has a function.

Its operation is explained in the Joki Kaikai. The user places the nozzle opening of the nozzle 18 between the opening of the packaging bag 14 in which the object to be packaged 13 is tied, and gently pulls the opening of the bag from side to side with both hands, so that the packaging bag 14 is heated with the lower pressing part 16a. Part 17a
Place it so that it covers the Next, remove one hand from the bag opening and hold the main body lid 15b to close it. Then, the bag l of packaging bag 14
The nozzle opening of the nozzle 18 is lightly held between the lower and upper pressing parts 16a and 16b, which have elasticity, and are pressed from above and below. This completes the setting of the packaging bag 14. Next, the packaging bag 1 is transferred from the nozzle l8 by an air pump.
4, and when enough air has been taken in, stop the air intake and pull the slide device fil9 inward. When the slide device 19 is retracted inward, the nozzle 18 is retracted. Thereafter, the heat pressing device 17b is quickly pushed downward, the bag opening of the packaging bag 14 is strongly pressed against the heating part 17a, and the heat sealing heater is turned on to seal the bag opening. After sealing is completed, the main body cover 15b is opened and the packaging bag 14 is taken out, thereby realizing sealed packaging.

Problems to be Solved by the Invention The first problem with such a conventional structure is that when the bag is set, the bag opening of the packaging bag may shift diagonally or become loose, causing wrinkles and an incomplete seal. This caused air to get trapped in the product immediately after it was completed.

The reason for this is that even if you pull the opening of the packaging bag with both hands to prevent wrinkles from forming and place it on the base of the main body, one of your hands must be removed from the opening of the bag in order to close the main body lid. This means that the packaging bag cannot be held tightly taut. In other words, if the seal is incomplete and air gets in, you may have to start over again, or you may have to pull the opening of the packaging bag again before sealing to prevent wrinkles from forming. When I noticed this, I had to set it up again. A second problem is that the packaging bags are attracted to the nozzle tip during suction, and the packaging bags come into close contact with each other, blocking the nozzle tip, making it impossible to continue suctioning any more. The reason for this is that the suction speed is highest near the nozzle tip, and therefore the packaging bags are attracted to each other and come into close contact with each other. Once the nozzle tip is blocked due to close contact, it is necessary to manually release the tightly stuck packaging bag to release the blockage. As described above, in the conventional configuration, the operator must always be careful when operating the device, making it inconvenient to use.

Therefore, the present invention aims to solve these problems, and its first object is to provide a hermetically sealed packaging device that is configured to ensure reliable sealing by preventing the sealing portion from being diagonally shifted or wrinkled. This is the purpose of A second purpose is to provide another means for achieving the first purpose.

Means for Solving the Problems The first means for achieving the first objective is to provide a main body base with a built-in pump, a main body cover rotatably attached to a part of the main body base, It is equipped with a nozzle for sucking the air inside the packaging bag in which clothes etc. are stored, a slide device for sliding this nozzle back and forth, and a sealing device for sealing the bag opening of the packaging bag. This sealed packaging device is provided with a slidable bag support for hooking the bag opening of the packaging bag. A second means for achieving the second object is a sealed packaging having a structure in which, in addition to the structure of the first means, a suction device for sucking the air inside the packaging bag is added to the bag support. It is used as a vessel.

The first means of action works as follows. A bag support is provided on one end of the heating section on the main body base so as to be in contact with the heat section, and the bag support is left protruding forward so that the user can place one end of the bag opening of the packaging bag on it. By hooking it, hold the other end with one hand and pull it left and right.
It is possible to maintain the state of being pulled left and right. At the same time, you can close the main body cover with your other hand. In addition, the bag support is slidable and can be pulled back just like the nozzle just before sealing to easily and reliably seal the packaging bag without getting in the way during sealing.

Moreover, the second means operates as follows. Similar to the nozzle installed in the center of the main body base, by connecting the bag support in parallel to the pump as an intake nozzle, there will be two nozzles, and even though the total intake amount is the same, it will be adjusted according to each intake resistance. Since the intake air amount of each nozzle is distributed, the suction speed near the tip of each nozzle can be reduced. In other words, even if the packaging bags come close to each other near the tip of one nozzle and the intake resistance increases, the presence of the other nozzle prevents it from being completely blocked, and therefore the intake air suddenly stops midway through intake. This can be prevented from becoming impossible.

EXAMPLE Hereinafter, an example of the present invention will be described based on the accompanying drawings. In FIGS. 1 and 2, reference numeral 1 indicates an object to be packaged, such as clothing, which is housed in a thermoplastic packaging bag 2. As shown in FIG. 3 is a sealed packaging device main body (hereinafter simply referred to as the main body), and this main body 3 is:

The lower pressing portion 4a and the upper pressing portion 4b are made of a resilient material such as rubber, and function to press the opening of the packaging bag 2 with good airtightness. 5a is the main body base 3
A heat sealing heater is embedded in a heat section provided on the inside of the lower pressing section 4a on the top a. 5b is the heat part 5a
It is a heat pressing device provided on the main body lid part 3b facing the , and is configured to be movable up and down. Heat pressing device 5b
normally remains raised, but has the function of pushing downward during sealing and strongly pressing the opening of the packaging bag 2 against the heating section 5a to ensure sealing.

Reference numeral 6 denotes a nozzle provided at the center of the main body base 3a, one end of which is connected via a pipe 8 to an air pump (not shown). This is a slide device that is connected to the nozzle 6 of No. 7 and can be slid back and forth. Reference numeral 9 denotes an L-shaped bag support, and one side of this L-shape protrudes from the base of the main body and comes into contact with the left end of the reheating part 5a and the lower pressing part 4a, and when the packaging bag 2 is set, this bag opening is It can be hung on the edge of the The other end of the bag support 9 is connected to a slide device 7, and by sliding the slide device 7 back and forth, it slides back and forth together with the nozzle 6. This slide device 7 is fixed in a pulled forward state when setting the packaging bag 2 or while sucking air inside the packaging bag 2, so that the tips of the nozzle 6 and the bag support 9 are attached to the packaging bag 2. It is designed to come to a position where it covers the opening of bag 2. When this suction is finished, the fixation is released and the nozzle 6 and the bag support 9 can be pulled back from the front by using the elastic force of a spring (not shown). Reference numeral 10 denotes a fixture provided at opposing positions of the main body base 3a and the main body cover 3b, which has a function of fixing the main body base 3a and the main body cover 3b so that they do not open when they are closed. There is.

Next, the operation of this embodiment will be explained. First, hook the left end of the bag opening of the packaging bag 2 containing the packaged item 1 onto the bag support 9,
Holding the nozzle opening of the nozzle 6, while lightly pulling the bag I to the left and right with one hand, place it so that it rests on the lower pressing part 4a and the heating part 5a, and close and secure the main body lid part 3b with the other hand. Fix firmly with tool 7. Then, the bag opening of the packaging bag 2 is pressed from above and below with the nozzle 6 and the bag support 9 between the elastic lower presser part 4a and the upper presser part 4b while being stretched from side to side. Setting of the packaging bag 2 is completed in the above manner. Next, the air inside the packaging bag 2 is sucked in through the nozzle 6 using an air bomb. When the suction is stopped and the slide device 7 is pulled inward, the nozzle 6 and the bag support 9 are moved in conjunction with this.
is drawn in. Thereafter, the heat pressing device 5b is quickly pushed downward, the bag opening of the packaging bag 2 is strongly pressed against the heating part 5a, and the heat sealing heater is turned on to seal one bag. After sealing is completed, the main body cover 3b is opened and the packaging bag 2 is taken out, thereby achieving a completely sealed packaging.

As described above, according to this embodiment, when setting the packaging bag on the main body base, the main body cover is held and closed with one hand, while the bag opening of the packaging bag is pulled with the other hand. As a result, the sealed packaging device is easy to use without causing the sealing portion to shift diagonally or becoming incompletely sealed due to wrinkles.

Next, a second embodiment will be explained based on FIGS. 3 and 4. In the figure, 1l is an L-shaped bag support, which is connected to a pump (not shown) via a vibrator 12 in parallel with the nozzle 6, and has a bag support nozzle l1a, and this bag support nozzle l.
It is composed of a connecting tool 1lb that connects the sliding device 7 and the sliding device 7. By sliding the slide device 7 back and forth, the bag support 11 is also slid back and forth together with the nozzle 6.

In this embodiment, by using two nozzles, the nozzle 6 and the bag support nozzle lla, at the same time, the number of nozzles becomes two, and the amount of intake air can be distributed according to the intake resistance of each nozzle. At the same time, the suction speed near the tip of each nozzle can be reduced. In other words, even if the packaging bags are sucked near the tip of one nozzle and the bags come into close contact with each other, increasing intake resistance, the presence of the other nozzle prevents the nozzle from becoming completely blocked. be. Therefore, it is possible to prevent sudden inability to inhale during inhalation.
