Description

[Detailed Description of the Invention] [Industrial field of application] The invention of this application relates to a heat-welding clamp for use in heat-sealing the open end of a synthetic resin bag.

[Conventional technology]

Heretofore, this type of heat welding sandwiching tool has not existed at all. Therefore, as shown in FIGS. 8 and 9, in a bag that is used by heat welding the open end of a synthetic resin bag at home, such as a compressed futon bag, as shown in FIGS.
The open end (12) of the bag (11) containing (10) is sandwiched between clothes scissors (13) at several points, and after being marked with an iron (14) or iron, the open end of the bag (11) The entire area of (12) was heat-welded.

[Problems to be solved by the invention] However, in the above heat welding method, the heat welding work is often troublesome and wrinkles often occur, and the open end (12) of the heat welded bag (11) is completely sealed. There was a problem that they could not do it.

Therefore, the invention of this application can be easily used when sealing the open end of a synthetic resin bag by heat welding, and in that case, there is no wrinkling at all for heat welding sandwiching. It was made for the purpose of providing ingredients.

[Means for Solving the Problems]

Therefore, in the heat welding sandwiching device of the invention of this application, a concave body (2) is provided in the longitudinal direction of one long plate (1a), and the concave body (2) is provided in the longitudinal direction of the other long plate (1b). The long plate (1a) is provided with a convex body (3) that can be freely fitted to the second plate.
Alternatively, one outer surface of the long plate (1b) is the heating surface (4).

And, the long plate (1a) and the long plate (1b) are
It can be made of a heat-resistant resin or a metal.

Further, a pressing body (5) may be provided on one of both ends of the long plate (1a) having the outer surface as the heating surface (3) or both ends of the long plate (1b).

[Action]

Since the convex body (3) can be freely fitted to the concave body (2) in the heat welding sandwiching device of the invention of this application, the heat-welded body is provided between the concave body (2) and the convex body (3). It is possible to sandwich and hold the heat-welded body so that it does not move.

In addition, in the heat-welding clamp of the invention of the present application provided with the pressing body (5), the vicinity of the heat-welded body sandwiched between the concave body (2) and the convex body (3) is the heating member. Prevent floating above the surface (4).

〔Example〕

Hereinafter, the construction of the heat-welding holding device of the invention of this application will be described with reference to the drawings showing examples.

(1a) is one elongated plate, and a concave body (2) is provided in the longitudinal direction of this elongated plate (1a). (1b) is
The other long plate, and in the longitudinal direction of the long plate (1b), a convex body (3) that can be fitted into the concave body (2) is provided.

Further, one outer surface of the long plate (1a) or the long plate (1b) is a heating surface (4). The elongated plate (1a) and the elongated plate (1b) are made of, for example, a heat-resistant resin or a metal so as to form the heating surface (4). As the heat-resistant resin, for example, a thermosetting resin such as urea resin, melamine resin, or epoxy resin is used, and as the metal, stainless steel, aluminum, or the like is used without particular limitation.

Further, a pressing body (5) can be provided on one of both ends of the long plate (1a) having the outer surface as the heating surface (4) or both ends of the long plate (1b). This pressing body (5) is provided on both sides of the long plate (1a) or both ends of the long plate (1b), which is the other side, from one of both ends of the long plate (1a) or both ends of the long plate (1b). It hangs and narrows the gap (6) between the two ends of each other.

Next, as shown in FIG. 3 to FIG. 7, the state of use of the heat welding sandwiching tool of the invention of the present application configured as described above is shown, for example, in the home by heat welding the open end of the compressed futon bag. The case where the above is used will be described.

First, as shown in FIG. 3, the futon (10) is stored in the bag (11). Next, as shown in FIG. 4, the heat-welding clamp of the present invention is inserted into the open end (12) of the bag (11).
Further, as shown in FIG. 5, an iron (14) is applied to the heating surface (4) of the heat welding sandwiching tool to heat it. And
As shown in FIG. 6, after the temperature of the heating surface (4) of the heat welding sandwiching tool is lowered, the concave body (2) and the convex body (3) are
Remove the mating of.

The above operation completes the thermal welding of the open end of the compressed futon bag. The temperature of the heating surface (4) of the heat welding sandwiching tool may be lowered by natural cooling, but by applying a cooling means such as an unheated iron to the heating surface (4). The temperature can be lowered quickly. By doing so, the heat-welded surface of the bag (11) is rapidly cooled and the welding strength is increased.

After that, as shown in FIG. 7, the suction pipe (16) of suction means such as a vacuum cleaner is applied to the opening / closing valve (15) to suck and remove the air in the bag (11). Then, the futon (10) is reduced in volume, and the futon (10) is hermetically stored in the bag (11) and stored in a closet or the like.

[Effect of device]

The heat welding sandwiching device of the invention of this application is configured as described above, so that the heat welded body is sandwiched between the concave body (2) and the convex body (3), and the heat welded body is Since it can be stopped so as not to move, the heat welding work is simplified and wrinkles are not generated, and the open end (12) of the heat welded bag (11) can be completely sealed.

Further, in the heat-welding clamp of the present invention, which is provided with the pressing body (5), the vicinity of the heat-welded body sandwiched between the concave body (2) and the convex body (3) is the heating surface. (4) Since it is prevented from floating above, the vicinity of the heat-welded body does not get in the way, and the heat-welding work becomes easier.
