[0010]

[Means for Solving the Problems]

 The case according to the present invention is a case including a quadrangular cylindrical main body, a bottom formed at the lower end of the main body, and a lid formed at the upper end of the main body, wherein the bottom has one side at the lower end of the main body. An inner bottom flap extending from the lower end of the main body and having an insertion hole formed therein; and an outer bottom flap extending from the other end opposite to one side at the lower end of the main body and having a tip portion inserted into the insertion hole. A bottom flap extending from another side at the lower end of the main body, the tip of which is inserted into the insertion hole, a notch is formed from the edge of the inner bottom flap to the insertion hole, and This is a case where a cut is formed in the bottom flap to insert the inner bottom flap. In the case according to the present invention, the cut is formed, for example, from the edge of the side bottom flap to the center. In the case according to the invention, the cut is formed, for example, from the tip of the inner bottom flap to the insertion hole.

In the case according to the present invention, when assembling the bottom, the tip of the side bottom flap and the tip of the outer bottom flap are inserted into the insertion holes formed in the inner bottom flap. Since the cut is formed from the edge to the insertion hole, the inner bottom flap is easily deformed, and the tip of the side bottom flap and the tip of the outer bottom flap are easily inserted into the insertion hole of the inner bottom flap. Therefore, in the case according to the present invention, the bottom is easy to assemble.

In the case according to the present invention, the tip of the side bottom flap and the tip of the outer bottom flap are inserted into insertion holes formed in the inner bottom flap. It is hooked on the prescribed part. For this reason, in the case of the present invention, even if a relatively heavy object such as a lotion or a hairdressing bottle is stored in the case, the tip of the side bottom flap and the tip of the outer bottom flap are kept. It is difficult for the inner bottom flap to come off from the part defining the insertion hole, and the bottom is hard to come off.

Further, in the case according to the present invention, a cut is formed in the side bottom flap, and the inner bottom flap is inserted into the cut, so-called play between the side bottom flap and the inner bottom flap is reduced. It becomes difficult for the bottom flap to come out of the insertion hole of the inner bottom flap.

In addition, in the case according to the present invention, since a cutout portion through which dust passes is not formed in the side bottom flap, it is difficult for dust to enter the inside from the outside.

The above and other objects, features and advantages of the present invention will become more apparent from the following detailed description of embodiments of the present invention with reference to the drawings.

[Embodiment of the invention]

 FIG. 1 is a perspective view showing an example of the case according to the present invention, and FIG. 2 is a developed view thereof. The case 10 shown in FIG. 1 is entirely formed of a synthetic resin such as polypropylene. The case 10 includes a quadrangular cylindrical main body 12. The main body 12 includes four side walls 12a, 12b, 12c, and 12d, and the four side walls 12a to 12d are connected in a quadrangular cylindrical shape by bonding a marginal portion 12e.

A bottom 14 is formed at a lower end of the main body 12. The bottom 14 includes an inner bottom flap 14a, two side bottom flaps 14b, 14c and an outer bottom flap 14d extending from lower ends of four side walls 12a, 12b, 12c and 12d of the main body 12.

A horizontally long insertion hole 16 is formed in the center of the inner bottom flap 14a. The insertion hole 16 is a hole for inserting the tip portions of the two side bottom flaps 14b and 14c and the tip portion of the outer bottom flap 14d when assembling the bottom 14.

Further, a rectangular cut 18 is formed in the inner bottom flap 14 a from the center of the tip to the insertion hole 16. This notch 18 deforms the inner bottom flap 14a when inserting the tip portions of the two side bottom flaps 14b and 14c and the tip portion of the outer bottom flap 14d into the insertion hole 16 of the inner bottom flap 14a. This is to make it easier.

The two side bottom flaps 14b and 14c are formed with, for example, S-shaped cuts 20b and 20c, respectively, from their ends to the center. These cuts 20b and 20c are for inserting the inner bottom flaps 14a when inserting the tip portions of the side bottom flaps 14b and 14c into the insertion holes 16 of the inner bottom flaps 14a.

Then, from the state where the bottom flaps 14a to 14d are opened as shown in FIG. 3, the inner bottom flap 14a is first closed as shown in FIG.

Next, as shown in FIG. 5, the two side bottom flaps 14b and 14c are closed. In this case, the tip portions of the two side bottom flaps 14b and 14c are inserted into the insertion holes 16 formed in the inner bottom flap 14a, and are hooked on the portions defining the insertion holes 16 of the inner bottom flap 14a. . In this case, the inner bottom flap 14a is inserted into the cuts 20b, 20c formed in the two side bottom flaps 14b, 14c.

Then, as shown in FIGS. 6 and 7, the outer bottom flap 14d is closed. In this case, the tip portion of the outer bottom flap 14d is inserted into the insertion hole 16 formed in the inner bottom flap 14a, and is hooked on a portion defining the insertion hole 16 of the inner bottom flap 14a.

In this case 10, since the cut 18 is formed from the edge of the inner bottom flap 14a to the insertion hole 16, the inner bottom flap 14a is easily deformed, and the tips of the two side bottom flaps 14b and 14c are formed. It is easy to insert the portion and the distal end portion of the outer bottom flap 14d into the insertion hole 16 of the inner bottom flap 14a. Therefore, in this case 10, the bottom 14 is easy to assemble.

In this case 10, the tip portions of the two side bottom flaps 14b and 14c and the tip portion of the outer bottom flap 14d are inserted into the insertion holes 16 of the inner bottom flap 14a, and the inner bottom flap 14a It is hooked on the part defining the insertion hole 16. Therefore, in this case 10, even if a relatively heavy object such as a bottle containing a lotion or a hairdressing agent is stored therein, the tip portions of the two side bottom flaps 14b and 14c and the tip portions of the outer bottom flap 14d. The portion does not easily come off from the portion defining the insertion hole 16 of the inner bottom flap 14a, and the bottom 14 does not easily come off.

Further, in this case 10, the inner bottom flap 14a is inserted into cuts 20b, 20c formed in the two side bottom flaps 14b, 14c, and the two side bottom flaps 14b, 14c and the inner bottom flap 14a are connected to each other. Since the so-called play becomes small, it becomes difficult for the two side bottom flaps 14b and 14c to come out of the insertion hole 16 of the inner bottom flap 14a.

Also, in this case 10, no cutout is formed in the two side bottom flaps 14b and 14c to allow the dust to pass through, so that the dust does not easily enter the inside from the outside.

A lid 22 is formed on the upper end of the main body 12 of the case 10. The lid 22 includes two side lid flaps 22b, 22c and an outer lid flap 22d extending from the upper ends of the three side walls 12b, 12c, and 12d of the main body 12. First, the two side lid flaps 22b, 22c are closed. Next, the outer lid flap 22d is closed.

FIG. 8 is a perspective view showing another example of the case according to the present invention. The case shown in FIG. 8 is formed to have a smaller overall width than the case shown in FIG. 1, and in particular, the cut 18 is formed in a straight line. In the case shown in FIG. 8, as in the case shown in FIG. 1, when assembling the bottom 14, first, from the state where the four bottom flaps 14 a to 14 d are opened as shown in FIG. The inner bottom flap 14a is closed as shown, then the two side bottom flaps 14b and 14c are closed as shown in FIG. 11, and finally the outer bottom flap 14d is closed as shown in FIGS. Can be In the case shown in FIG. 8, similarly to the case shown in FIG. 1, the insertion hole 16 and the cut 18 are formed in the inner bottom flap 14a, and the cuts 20b, 20c are formed in the side bottom flaps 14b, 14c. Therefore, an effect similar to that of the case shown in FIG. 1 is achieved.

In each case 10 described above, a rectangular or linear cut 18 is formed in the inner bottom flap 14a, but the shape of the cut 18 is not particularly limited.

In each case 10 described above, the S-shaped cuts 20b, 20c are formed on the side bottom flaps 14b, 14c, but the shape of the cut is not particularly limited.
