Figure 4 is the description! A schematic view of the relationship between the sealing strip 1〇 and the second sealing strip 2〇 and the arrangement of the hand bag 30. For convenience of explanation, the first sealing strip μ and the second sealing strip α and the hand bag 30 are shown separated. The length C2 of the hand bag 7054-10404-PF:11 along the longitudinal direction of the first sealing strip 10 is longer than the length C1 of the central portion 39 other than the side wrapping portion 33 in the cross section of the handle. For example, the length C2 is preferably a length. ... to the position -. Further, the thickness T2 of the convex portion η is preferably about 2 厚度 of the thickness T1 of the film of the packaging material of the hand bag 3〇. 2 times the sum of 1 and I fl, for example, the thickness T2 of the convex portion 11 is h8 to 2.2 times the thickness T1, and preferably U to 2 times. For example, and because the diaphragm has a thickness of 105 to 110, the projection 11 preferably has a thickness in the range of 210 to 220 μm. A list of the use states of the sealing device 本 of the present embodiment will be described with reference to Fig. 5 . Fig. 5 is a schematic view showing an example of the state of use of the sealing device 1. The closing device 1 sets the seal/$degree and time on the control unit 4 according to the shape of the handle bag 3, and requires pressure or the like for the pressure contact. The control unit 4 energizes the nickel-chromium wire U by the setting to excite the driving unit. The second seal is 2. The hand bag 3 is sandwiched between the first sealing strip 1〇 and the second sealing strip 20 which are electrically heated and heated to close the first sealing strip 1 side to perform sealing. In a state in which the handle & 30 is sandwiched between the j-th sealing strip 1〇 and the second sealing strip 2〇, the 'partial side wrapping portion 33 is formed by the front surface 34 and the rear surface 35 of the hand bag 30. The diaphragm 'and the folding are formed as a width of the side surface, and a total of four diaphragms of the I5 knife and the two side surfaces 31 of the folded apex 32 are superposed. On the other hand, in the cross section of the hand bag 30, the center portion 39 other than the surrounding portion 33 is formed by overlapping two diaphragms constituting the front surface 35 of the hand. Therefore, the thickness of the center portion 39 and the example portion 33 of the hand bag 30 is different, and the side wall portion 33 is substantially twice as thick as the center portion 39.

7054-10404-PF 1357395 A convex portion η having a thickness substantially the film is provided in the i-th sealing strip 1Qj1. Therefore, when configured such that the hand bag 2: the portion 39 and the convex portion 11 correspond, the hand bag is in the first! When the convex portion 11 is provided on the sealing strip 10, it becomes flat. Furthermore, when the thickness of the convex portion η is more than 2 times larger than the thickness of the diaphragm, the middle two portions 39 of the hand bag 3 反 are more prominent than the side wrapping portions 33 because they are not flat, 曰, It is unpopular. The thickness of the projection u is preferably substantially about twice the thickness of the diaphragm. Further, as described below, the both end portions iia and ub in the longitudinal direction of the convex portion u extending in the longitudinal direction of the i-th sealing strip ι are arranged such that the apex 32 of the side wrapping portion 33 is disposed and One of the portions in which the four diaphragms are overlapped is placed on the convex portion 21. Thus, for example, the thickness 12 of the projection 11 may be a thickness of 2 times (four) the thickness of the diaphragm. The length C 2 along the longitudinal direction of the first sealing strip i 凸 of the convex portion 11 is the length of the central portion 39 in the cross section of the hand bag 30. Therefore, when the hand bag 30 is disposed such that the center portion 39 corresponds to the convex portion n, it is configured such that the apex 32 of the side bulb portion 33 runs to the end portion 1 la, 1 lb side of the length side θ of the convex portion 11 . The length at which the vertex side of the side wall portion 33 is in contact with the convex portion j j is, for example, in the range of 1 mm to 3 nm. With this arrangement, when the second sealing strip 20 is pressed against the pocket 30, the portion (side portion 33) of the four diaphragms and the portion (the central portion 39) of the two diaphragms where the small holes are likely to be generated are The border is actually pressed and crimped by the opponent's bag 30. According to this embodiment, the small hole can be produced and the hand bag 30 having the difference in thickness in the cross section can be surely sealed. Further, since it is not necessary to raise the temperature to a necessary level in order to surely perform the sealing, the central portion 39 other than the side wrapping portions 7054-10404-PF 10 I357395 33 is not easily burned in the cross section of the hand bag 30. turbid. According to the present embodiment, heat conduction is performed by sealing by means of a sealing device including the heat generating portion 13 in any of the first sealing strip 1 and the strip 20. According to the present embodiment, since the embossed gentleman and the tenon forming material lie are disposed between the sealing main body 15 and the heat generating portion 13, and can be used in the existing sealing device. The convex portion 11 becomes the manufacture of the upper sealing device of the present invention. M1' can be performed briefly. [2] Second embodiment Next, the second embodiment will be described. Fig. 6 is a schematic view showing a sealing portion of the first embodiment in the first embodiment. In the second embodiment, only the portions different from the first embodiment will be described. The other portions are the same as those of the i-th embodiment. The convex portion u of the second sealing strip m of the second embodiment is formed by integrally forming the convex portion material Hd from the sealing strip main body 15A. The heat-resistant tape 12, the chrome-plated wire 13, and the heat-resistant tape 14 are alternately overlapped on the sealing strip main body i5A integrated with the forming material 11d of the convex portion 11. The second seal and the second seal do not include the chrome-plated wire 13 and the heat-resistant tape 12, so that the seal portion 7A of the second embodiment has a heat-generating portion only on the - side. Also with such a configuration, the same effects as in the first embodiment can be obtained. According to the present embodiment, since the convex portion forming material lid is integrated with the sealing strip main body 15A, the durability against the force applied to the convex portion uA is improved. The embodiment of the present invention is not limited to the above embodiment ’ and the technical scope of the present invention is not limited thereto. For example, in the first and second embodiments, the convex portion 11 is provided in
