【Example】

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. Figures 1 and 2 are books The top side and the bottom of the tube container according to the invention are not sealed. FIGS. 3 and 4 are perspective views of the tube container according to the present invention. FIG. 6 is a cutaway perspective view and a side sectional view of the main body in a state where the bottom portion is not sealed.

[0008] As shown in FIG. 1, the container body 10 is roughly divided into a body section that forms a storage section for cosmetics, etc. 12 and a neck portion 16 having a slightly smaller diameter than this body portion 12, and the circumference of the neck portion 16 is A thread 20 is formed on the enclosure for screwing a lid (not shown). Ma In addition, a spout 18 for pouring out the contents of the container body 10 is provided on the top surface of the neck portion 16. I'm being kicked. Furthermore, as shown in FIGS. 2 and 3, the inside of the container body 10 is The longitudinal direction of the container body 10 is provided by a corrugated partition wall 22 extending in the inner diameter direction of the body 10. The container body 10 is divided into two chambers, and different contents stored in each chamber are stored inside the container body 10. I try not to mix them in the section. The spout 18 is opened in each of the two chambers. The contents stored in each chamber can be taken out individually.

[0009] 5 to 7 show how to press the bottom of the container body 10 to seal it. FIG. Figure 5 shows the initial state before pressing, and Figure 6 shows the state in the middle of pressing. FIG. 7 shows the fully pressed state. Here, as shown in Figure 7, When the bottom of the container body 10 is completely pressed down, the width W of the bottom is shown in FIG. This is approximately 1/2 of the inner circumferential length of the trunk peripheral wall 14 forming the trunk 12 in its initial state. On the other hand, when the corrugated partition wall 22 is expanded into a flat plate, the developed length is as follows: It is manufactured so that it is approximately 1/2 of the inner circumference length of 4. Therefore, the corrugated sheet finish The cut wall 22 and the two-layer body circumferential wall 14 sandwiching it form three layers and are in close contact with each other. If the thickness of the wall 14 is t and the thickness of the partition wall 22 is t', then the thickness of the bottom to be sealed is is uniformly (2t+t'), and the working conditions for heat sealing or ultrasonic sealing are It can be easily determined based on the wall thickness and can be sealed reliably. be.
