うような欠点があつた。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a back seal for a multilayer laminate tube. Conventionally, both ends of a multilayer laminate sheet are heated with a gas burner, etc. It was common to manufacture a laminate tube by melting the thermoplastic resin, then overlapping both ends, pressing the overlapping part, and sealing the back, but in this case, the surface was heated with a gas burner, etc. As a result, the resin on the surface burns, sometimes exposing the intermediate layer such as paper or aluminum foil, and the overlapping part inevitably becomes thicker, resulting in poor appearance.Furthermore, the resin surface burns and foams. It becomes necessary to cover the overlapping portion by pouring tape or resin over it. Further, these conventional methods have drawbacks such as incomplete end face protection and the thickness of the overlapping portion after sealing is nearly twice that of a multilayer laminate sheet.

In this example, a high-frequency induction heating method was used, but room temperature heating, thermal heating,
Although an ultrasonic heating method may be used, a high frequency induction heating method is preferable, and in FIG. 2, 4 indicates an electrode of a high frequency induction heating device.

トシート１の本体部分の厚みが薄くなる。 At both ends 2 and 3 of the pre-pressed laminate sheet 1, a pre-pressed portion f is formed as shown in FIG. 3, and the thermoplastic resin layers a, c and e flow out into this pre-pressed portion f. , a flowed resin layer g is formed to completely cover the other paper layer b and aluminum foil layer d. Also, at this time, the thermoplastic resin layer flows out of the preliminary press section f, and the thickness of the main body portion of the multilayer laminate sheet 1 becomes thinner.

の本体の一枚分の厚みに相当するようにする。 As the next step, the pre-pressed parts f of the multilayer laminate sheet 1, whose both ends have been pre-pressed, are wrapped around a mandrel so that they overlap to form a cylindrical shape.
The overlapping portion 5 is heated and pressed using a high frequency induction heating method, and the back is sealed as shown in FIG. 3 to produce a multilayer laminate tube 6. Here, in the overlapping part 5 of the multilayer laminate tube 5, the outflowing resin g that has flowed out during the preliminary pressing further flows out in the back sealing process to form the outflowing resin h, as shown in FIG. sheet 1
The thickness should be equivalent to the thickness of one sheet of the main body.

る。 In addition, in the present invention, preliminary press parts f are provided at both ends of the multilayer laminate sheet 1 in the first step, and the overlapping parts 5 are heated and pressed in the next back sealing process, so the thermoplastic resin in the preliminary press parts f is poured out. , since the thickness of the overlapping part 5 can be made equivalent to one sheet of the original multilayer laminate sheet 1, the flowed resin layers g and h can completely cover the joint part. The appearance of the product is excellent, and the texture is also improved.

In addition, not only can the defect rate be significantly reduced by pressing twice, but even though there are two pressing steps, high-frequency sealing is less time-consuming than gas burner heating.
