した稜線を形成する。《Operation》 When one layer and two layers of thermoplastic resin are arranged alternately in the circumferential direction and extruded into a spiral sleeve, the first layer is made of low density polyethylene and the second layer is made of high density polyethylene and low density polyethylene. Since both resins are made of polyethylene, they are bonded together due to their mutual compatibility, but due to the difference in heat shrinkage rates between low-density polyethylene and high-density polyethylene, the joint of both resins forms a raised ridgeline.

り、略菱形の変形スリーブとなるのである。 The body 1 is formed from a cylindrical sleeve 1a, as shown in FIGS. 3 and 4. The cross-sectional shape of this sleeve 1a is a modified rectangular shape,
The wall surface is provided with double-layered portions 7 and single-layered portions 8 alternately in the circumferential direction. The two-layer portion 7 has an inner wall portion 7a made of high-density polyethylene, which is a relatively hard thermoplastic resin, and an outer wall portion 7b, which is made of low-density polyethylene, which is a relatively soft thermoplastic resin. Further, the single-layer portion 8 is formed from the same type of low-density polyethylene as the outer wall portion 7b of the second-layer portion 7. These two-layer portions 7 and single-layer portions 8 are extruded from annular nozzles adjacent to each other alternately in the circumferential direction, and during extrusion, the nozzles are slowly rotated and the extruded The two-layered portion and the single-layered portion of the sleeve are formed in a spiral manner. After such extrusion molding, the sleeve portion is cooled, and at this time, due to the difference in shrinkage rate between the high-density and low-density polyethylene, the boundary joining portion between the two forms a raised ridgeline 9. , resulting in a substantially diamond-shaped deformed sleeve.

極めて便利である。<<Effects>> As described above, in the tube container according to the present invention, the sleeve portion is formed by disposing the single layer portion and the double layer portion of the thermoplastic resin alternately in the circumferential direction and extruding them into a spiral sleeve shape. using
Since the single-layer portion is made of low-density polyethylene, the inner wall of the two-layer portion is made of high-density polyethylene, and the outer wall is made of low-density polyethylene, the joint between the two resins bulges due to the difference in heat shrinkage rate of the two resins. When you look at the cross-sectional shape of the ridge line, you can see that the polygonal corners are protruding, giving it a unique appearance. The polygon shape is easily deformed by taking advantage of the properties of the resin, so even if external heat is applied to the sleeve during later decoration, the square shape will not collapse, making the decoration work more efficient. can do well. In addition, the raised ridgeline mentioned above functions as a rib, and when the pressing force applied to the body is released during use,
The torso immediately returns to its original state, making it extremely convenient to use.
