Has been formed. 5 is a spout part to which a cap 6 is attached. Further, the shoulder portion 12 and the bottom portion 13 have a slightly bulged shape. Then, two V-shaped grooves 11, 11 extending in the opening direction of the mold at the time of molding are formed on the bottom surface of the bottom portion 13. For this reason, the mold release at the time of molding is smooth, and the bottle 2 is easily crushed.

As shown in FIG. 1, narrow side grooves 8 and 8 are formed on both side surfaces 7 and 7 as a body peripheral wall of the bottle 2 in the vertical direction.

In each of the grooves 8, both edge portions of two cardboards 9 and 10 that form the cylinder body 3, that is, both edge portions located at a joint portion (joint) of the cylinder body 3, 9 a and 10 a. , 9b and 10b are overlapped and press-fitted.

As shown in FIG. 2, the groove 8 has an inverted wedge-shaped cross section, and a projection 11 1 is formed on its inner wall surface. As a result, the edge portions 9a and 10a, 9b and 10b of the thick papers 9 and 10 press-fitted into the groove 8 are overlapped with each other and the pressing force from the projection 11 causes the groove 8 to be pressed into the groove 8. The press-fitting condition is firm. Therefore, the cylindrical body 3 is firmly fixed to the container body 2.

The attachment of the cylinder 3 to the bottle 2 according to the first embodiment may be performed after the bottle 2 is filled with the contents in advance, or before the contents are filled. In particular, in the former case, it is possible to prevent the liquid from dripping into the cylindrical body 3, and it becomes difficult for the bottle 2 to deform due to the filling of the contents, and the press-fitted fitting state with the cylindrical body 3 is displaced during the work. There is an advantage that there is no fear. Further, since the shoulder portion 12 is slightly bulged, it is possible to prevent the cylindrical body 3 from sliding down when the contents are poured.

In FIG. 6, reference numeral 21 denotes a storage container for storing a softening agent as a content, and a bottle 22 as a main body of the container filled with the softening agent is slightly bulged above the waist and a handle 23 is provided. .

As shown in FIG. 4, narrow grooves 25, 25 are formed on both side surfaces 24, 24 as the body peripheral wall of the bottle 22 in the vertical direction.

In each of the grooves 25, both edge portions of two thick papers 27 and 28 constituting the cylindrical body 26, 27a and 28a, 27b and 28b are overlapped and press-fitted.

As shown in FIG. 5, the groove 25 has an inverted wedge-shaped cross section. On the other hand, a thick portion 29 is formed on each edge of the thick papers 27 and 28, for example, 27a and 28a. As a result, the edges 27a and 28a, 27b and 28b of the thick papers 27 and 28 press-fitted into the groove 25 are overlapped with each other and the contact with the thick portions 29 causes the grooves 27a and 28a, 27b and 28b to overlap with each other. The press-fitted state of 25 is made firm. Therefore, the cylinder 26 is firmly fixed to the bottle 22.

The storage containers 1 and 21 having such a configuration are suitable for mass production because they can be assembled simply by mounting the cylinder from the outer periphery of the bottle. Also, the cylinder and the bottle are firmly fixed. Further, since the upper part of the waist is slightly bulged, it is possible to prevent the cylindrical body 26 from slipping down when the contents are poured.

Second Embodiment FIG. 7 shows a second embodiment, in which 31 is a quadrangular prism-shaped bottle as a container body. On the bottom surface portion 32 of the bottle 31, one narrow groove 33 is formed.

As a result, it is extremely easy to assemble. Further, the flap 37 once press-fitted into the groove 33 tries to open in the direction orthogonal to the load of the bottle, and on the other hand, since the width of the groove 33 is narrow, the flaps 37 are pressed against each other, whereby the bottle 31 Does not easily come off from the box 34, and the fixed state is good.

(Third Embodiment) FIG. 8 shows a third embodiment, in which reference numeral 41 denotes a square-shaped bottle as a container body. The bottle 41 is formed such that the shoulder portion is slightly bulged, and one narrow groove 43 is formed around the entire circumference of the base portion 42.

Reference numeral 44 denotes a box as a cylinder made of cardboard that holds the bottle 41, and a flap 46 that is folded back toward the bottle 41 is provided on each of the lower edge portions 45 of the side surface of the box. .
