C Problems to be Solved by the Invention] As mentioned above, the method of attaching the hanging string to the bag body using a fastener such as a stapler involves positioning the lower end of the hanging string at the upper edge attachment part of the bag body. Complex work processes are required, including the process of joining the pieces together and the process of accurately securing both ends with fasteners, which complicates the manufacturing process.If the bag becomes heavy due to being immersed in water, the hanging string can easily be attached. There was a problem that it often came off.

In addition, if the above-mentioned methods of attachment using seals are used, the bag is limited to bags that are sealed on three sides, the left and right edges and the upper edge, and the attachment force of the hanging string by adhesive seals is weak. When the bag, which has become heavy due to soaking, is being swung up and down on a hanging string.

There was a problem in that the hanging string would come off the seal and fall out.

[Means for solving problems]

The present invention was developed in order to solve the above-mentioned problems, and its purpose is to attach the hanging string to the seal part by sealing and adhering it together when forming the seal of the bag body. A pack with a hanging assembly that can provide a center-sealed bag with a vertical seal at the center as one bag, and can firmly attach a hanging string to one bag with both the vertical seal and the horizontal seal. In the present invention, packaging paper having water permeability and heat sealability is vertically sealed by overlapping both ends so that the entire paper forms a substantially cylindrical body, and at the same time, the vertically sealed portion is A vertical sealing process in which seals are welded at intervals along the middle of one long and thin hanging string, and a vertical seal in which the hanging string is welded while the vertical seal is positioned at the center of the cylindrical body. A horizontal sealing process in which a horizontal seal is added to the cylindrical body so as to cross the cylindrical body and the brewed product is sealed inside, and the central part of the horizontal seal is bisected vertically together with a hanging string, and the hanging string is A notch or a perforation-like separation line is formed on the vertical seal so that the vertical seal can be separated from the vertical seal side while leaving a part of the vertical seal welded as a grip on the hanging string side. By a manufacturing method consisting of a cutting process.

Each of the objectives mentioned above has been achieved.

[Effect]

A hanging assembly pack manufactured using the manufacturing method of the present invention having the above configuration has a vertical seal located in the center of the bag, and a center seal with horizontal seals at both upper and lower ends. A seal is formed on the seal bag, and when used,
If the tab is separated along the separation line formed on the vertical seal, this tab attached to the hanging string becomes a tag for hanging the bag, and the lower end of the hanging string is separated by two vertical and horizontal seals. It is firmly sealed and welded to the bag body side.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A method of manufacturing a pack with a hanging assembly according to the present invention will be described in detail below based on illustrated embodiments.

In carrying out the present invention, first, the entire wrapping paper 1, such as filter paper, which has water permeability, heat sealability, and sealability is formed using a forming member (not shown) as shown in FIGS. 1 and 2. As shown in the figure, it is formed into a substantially cylindrical body IX, and its both end edges 1a are stacked vertically. 5 Then, a vertical sealer (not shown) is applied.
Vertically seal the overlapped ends @la using .

In addition, when performing this vertical seal IT, as shown in the figure, one long and thin hanging cord 2 is inserted between both ends #la with the middle part 2b being intermittently overlapped with the middle part 2a being slack. do. Therefore, the above-mentioned hanging string 2 is seal-welded at intervals to the vertical seal 1T of the substantially cylindrical body IX at the intermediate portion 2b.

In the next step, a pair of horizontal sealers (not shown) are attached to the cylindrical body I.
It is sandwiched from both sides of X to form a horizontal seal IS. Horizontal sealing IS using a pair of horizontal sealers can be performed by clamping both horizontal seals against the cylindrical body 1X from both left and right sides as shown in FIG. The cylindrical body 1x is twisted by 90 degrees and supplied to the horizontal sealer, and the front and rear horizontal sealers are clamped onto the supplied cylindrical body IX.

FIG. 3 shows the state after the above-mentioned horizontal sealing process has been performed, and with this horizontal seal IS, the above-mentioned vertical seal IT is placed in the center position of the bag body IP as shown in FIG. In addition, the horizontal seal IS is especially performed so as to cross the part of the vertical seal IT where the midway 2b of the hanging string 2 is seal-welded, so that the hanging string 2 The middle 2b part is the vertical seal IT and the horizontal seal IS.
The seal is firmly welded to the bag IP side. In addition, while performing the horizontal sealing IS, various kinds of souvenirs 3 such as black tea and green tea are supplied and sealed inside the bag IP as shown in FIGS. 3 and 4.

FIG. 5 shows the cutting process of bisecting the center of the horizontal seal IS vertically along the line R including the hanging string 2 using a cutter (not shown) provided at the lower stage of the horizontal sealer, and A notch that can be cut from the vertical sealing process side with a part of the vertical seal IT left on the hanging string 2 side as a knob 4 on the bottom side of the vertical seal IT applied to the bag body IP, or , which shows a state in which a cutting process is performed to form a separation line 5 such as a perforation, and by performing both of these cutting processes, one hanging puncture is manufactured.

The above-mentioned separation line 5 is formed by cutting two lines so as to sandwich the part of the vertical seal IT into which the hanging string 2 is inserted from both sides as shown in FIG.
The lines 5, 5 of the book are formed in a cross-shaped shape, and especially in the second drawing, the lower line 5 is the hanging string 2 inserted.

It is a so-called center seal bag, and when the tab 4 is separated from the vertical seal IT along the separation line 5 as shown in the figure, the tab 4 becomes a tag for hanging, and the entire pack P is hung. It can be hung with the hanging string 2.

〔effect〕

The method for manufacturing a pack with a hanging assembly according to the present invention is as described above, and (1) in the pack with a hanging assembly manufactured according to the present invention, the hanging string becomes longer when the grip part is separated from the vertical seal. Use this tab as a hanging tag to hang the whole pack, put it in a cup, pour boiling water into it, and shake it up and down. However, the present invention is particularly capable of providing a pack (tea bag) with a hanging assembly and a center seal that has a novel shape that has never been seen before, and is highly functional. In addition, since the hanging string is sealed and welded to the bag body side with two seals (vertical seal and horizontal seal) on the root end side, the attachment is extremely strong and does not become heavy due to immersion. Even if you hang the bag and swing it up and down, the WJ weld will not simply come off and the hanging string will come off, so you can safely swing the bag up and down repeatedly to thoroughly infuse. It can be used very effectively for manufacturing bags for various memorial items such as black tea, green tea, and health foods.
