  According to the present invention, since the quantitative crease line 13 that can be easily horizontally folded in the front-rear direction of the trunk portion 10 is provided, the contents in the trunk portion 10 are pushed out from the lower end, and the quantitative crease line 13 is It is possible to discharge a fixed amount by pushing out to the part, and then bending the barrel 10 from the portion of the fixed crease line 13 to fill the filling area and the non-filling area (pressing the trunk 10). Can be easily separated from the filled region, and the lower unfilled region folded down can be folded back to the rear surface or the front surface of the body portion 10 of the filled region. Therefore, the bent state can be stably maintained.

  When the fixed crease line 13 is constituted by a horizontal annular linear recess 14 formed on the outer periphery of the body portion 10, the same effect as the effect described in the above paragraph 13 is exhibited, and the length of the fixed crease line 13 is also shown. Can be formed as long as possible, so that easier bending is possible.

  When the fixed crease line 13 is constituted by a horizontal non-annular linear recess 15 having a discontinuous portion 16 at least in one of the front and rear positions of the body portion 10, the same effect as the effect described in paragraph 13 above is obtained. In addition, the outer surface of the body portion 10 of the discontinuous portion 16 can be effectively used. For example, a label can be attached to the portion.

  When the discontinuous portion 16 on the outer surface of the body 10 is configured as the display surface 17, the same effect as described in the paragraph 13 can be exhibited, and the display surface 17 can be formed without distortion even if it is printed or the like. There are advantages.

  When a plurality of fixed crease lines 13 are provided, the container can be used in multiple divisions more than two divisions depending on the purpose of use, etc., and from the beginning to the end of use of the container, It is possible to maintain a stable separation state in the unfilled region.

  A cap body B1 having a discharge port 21 opened on a top plate 22 extending from the upper end of a peripheral wall 20 fitted to the mouth-and-neck portion 12, and a bar for closing the discharge port 21 while providing the cap body B1 to be openable and closable. When the cap B composed of the lid B2 having the stopper 33 is mounted, the outlet 21 is closed by the rod stopper 33 by closing the lid B2 after discharging the contents. Therefore, there is an advantage that the contact between the filling region of the contained material defined inside and the outside air can be minimized.

The quantitative crease lines 13 in the present example are respectively composed of horizontal annular linear recesses 14 formed on the outer periphery of the body part 10, and each quantitative crease line 13 extends from the lower part to the upper part of the body part 10. It is recessed by the space | interval from which the amount of accommodation between them becomes the same. Accordingly, in the illustrated example, a plurality of recesses are provided at equal intervals. However, the distance between the lowermost quantitative crease line 13a and the closed portion 10a at the lower end of the container body A is different from the shape of the body 10 between the lower crease line 13b from the bottom immediately above it. The lower fold line 13a is recessed at a predetermined length from the lower end so that the lower volume and the upper volume are the same. In addition, the upper part of the second fixed crease line 13b from the bottom is formed at equal intervals because the body shape is the same. The number of quantitative crease lines 13 may be appropriately selected depending on how many times the contents are divided and used, and not only in the case of providing a plurality as in this example, but also by providing one quantitative crease line 13 and dividing it into two. You may comprise so that discharge may be performed.

  The fixed crease lines 13 formed by the horizontal annular linear recesses 14 can be formed before or after the container body A is formed. The other embodiments are the same with respect to the formation of the linear recess.

  The cap B is composed of a cap body B1 and a lid body B2. The cap body B1 extends from the upper end of the peripheral wall 20 fitted to the outer periphery of the mouth-and-neck portion 12 with a top plate 22 having a discharge port 21 at the center. Further, a seal cylinder 23 suspended from the back surface of the top plate 22 is liquid-tightly fitted to the inner peripheral upper end portion of the mouth / neck portion 12. The lid body B2 is in the form of a flat plate with the top wall portion 31 extending from the upper end edge of the peripheral wall portion 30, and the rear lower end of the peripheral wall portion 30 is integrally connected with the upper end of the peripheral wall 20 rear portion of the cap body B1 and the hinge 32, The upper surface of the cap body B1 is provided so that it can be opened and closed. Further, the discharge port 21 is closed by fitting a rod plug 33 suspended from the back surface of the top wall portion 31 into the discharge port 21.

  In use, the tube container 1 configured as described above can discharge the contents from the discharge port 21 by opening the lid B2 from the state of FIG. After crushing the body part 10 to the fixed crease line 13a, the body part 10 is horizontally folded at the lowermost part of the crease line 13 as shown in FIG. . The bent lower end can be stored by being bent, for example, from the state shown in FIG. 2 until it contacts the front surface of the body 10.
