Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bottle-shaped container, and more particularly to a bottle-shaped container made of synthetic resin having an opening at its upper end.

[0002]

2. Description of the Related Art Conventionally, glass bottles have been widely used for filling and supplying or storing liquids such as various drinks and chemicals. However, since glass bottles are heavy and have the drawback of being easily broken, bottle-like containers made of synthetic resin have been used instead of such glass bottles.

A bottle-shaped container made of synthetic resin can be obtained by placing an extruded hollow parison in a mold and blowing air into the mold to perform blow molding. Such a blow-molded container has substantially the same shape as a glass container, and has a mouth formed at the upper end.

[0004]

Generally, a bottle-shaped container made of a synthetic resin molded body is advantageous in that it is lightweight and more resistant to impact than glass. However, it has a drawback that it requires a space for disposal after use.

Steel cans and aluminum cans do not become bulky by being crushed after use. On the other hand, in the case of a bottle-shaped container made of synthetic resin, even if it is crushed after use, air will enter through the mouth and it will automatically restore to the shape of the original bottle-shaped container. It doesn't make sense to fold it, compress it, and throw it away. Therefore, such a bottle-shaped container has a problem that it requires a space at the time of disposal.

The present invention has been made in view of the above problems, and an object thereof is to provide a bottle-shaped container in which an empty container is not bulky at the time of disposal after use. is there.

[0007]

According to the present invention, there is provided a synthetic resin bottle-shaped container having a mouth portion at an upper end thereof, wherein a body portion is made of a foldable flexible synthetic resin material and is engaged with the mouth portion. The present invention relates to a bottle-shaped container in which an engaging portion is continuously provided on the bottom side.

[0008]

After use, the flexible body portion is folded, and the engaging portion continuously provided on the bottom side is engaged with the mouth portion to maintain the folded state. The original bottle-like shape will not be restored.

[0009]

1 to 5 show a bottle-shaped container according to a first embodiment. As shown in FIG. 1, this bottle-shaped container includes a container body 10 having a square cross section formed by blow molding polyethylene resin. The container main body 10 is formed with ribs 11 forming a joint portion at the time of blow molding so as to extend in the longitudinal direction in the body portion. A mouth 12 is formed on the top of the container body 10. The mouth portion 12 constitutes a spout for the liquid filled inside, and the cap 13
Is to be screwed on.

Next, the structure of the bottom of the container body 10 will be described with reference to FIGS. 2 and 3. Container body 10
An engagement ring 18 is continuously provided on the bottom surface 17 of the through a connecting portion 19. The lower end of the connecting portion 19 is a hinge 20. The engagement ring 18 and the connecting portion 19 are preformed on the preform. The engaging ring 18 is housed in a recess 21 formed on the bottom surface 17, and is locked by locking portions 22 formed on both sides of the recess 21, as shown in FIG. It does not protrude from the bottom surface 17.

The engaging ring 18 rotates the hinge 20 at the lower end of the connecting portion 19 so that the engaging ring 18 is housed in the recess 21 as shown in FIG. It is used in a locked state. Therefore, even if such a container is provided with the engaging ring 18 at the bottom, it does not prevent the container from being stably placed on a flat table. Then, such a container body 10 is filled with, for example, a beverage, and the mouth portion 1
2 is screwed by the cap 13 and used for physical distribution.

When the container is discarded after drinking the beverage supplied by such a container, the engaging ring 1 is located at the hinge 20 of the connecting portion 19 as shown in FIG.
Raise 8 at a right angle as shown in FIG. And after this,
As shown in FIG. 5, the side portion on which the rib 11 is formed is folded inward, and the intermediate portion in the height direction of the side plate portion on which the rib 11 is not formed is folded. Then, the bottom surface 17 is bent so that it is almost at the same position as the mouth portion 12.
After that, the engagement ring 18 is engaged with the mouth portion 12 to which the cap 13 is screwed. The cap 13 of the mouth 12 may be removed and the engagement ring 18 may be engaged. As a result, as shown in FIG. 5, the container body 10 is pressed by the engagement ring 18 so as not to return to its original shape in the folded state.

As described above, the bottle-like container according to this embodiment has the engaging ring 18 housed in the recess 21 formed in the bottom surface 17 thereof, and the hinge 2 is used after use.
The engaging ring 18 is raised at 0, the body portion is folded, and the engaging ring 18 is engaged with the mouth portion 12. Therefore, the original shape is not restored after folding and crushing, and the volume reduction effect is extremely high, and the weight reduction effect after disposal is very high.

Next, a second embodiment will be described with reference to FIGS. In this embodiment, the container body 10 is composed of a bottle-shaped container made of polyethylene resin whose upper end side is narrower. The container body 10 is provided with ribs 11 extending in the vertical direction at four corners thereof. In addition, a handle 26 is continuously provided at a predetermined position on the body, and the handle 26 is located above the step 27 of the body.

Further, on the bottom surface 17 of the container body 10,
As shown in FIGS. 7 and 8, engagement rings 18 similar to those of the first embodiment are continuously provided, and can be rotated at hinges 20 of a connecting portion 19. And bottom 1
7 is accommodated and held in the recess 21 formed in 7, and the locking portion 2
It is designed to be locked by 2.

Therefore, even in such a bottle-shaped container, after use, as shown in FIG. 9, the body portion is bent about 180 ° at an intermediate position in the height direction. Then, the engaging ring 18 formed on the bottom surface 17 is raised at the hinge 20 of the connecting portion 19, and the engaging ring 18 is engaged with the mouth portion 12 so that the folded state is maintained. The original shape as shown in is not restored. Also in this case, the cap 13 may be screwed on the mouth portion 12 or may be removed. Therefore, also in such an embodiment, it is possible to obtain the same effect as that of the first embodiment.

Next, a third embodiment will be described with reference to FIGS. In the third embodiment, the engagement ring 18 is formed not on the bottom surface of the container body 10 but on the body portion at the lower end side thereof. That is, a step portion 30 opened downward is formed below the step portion 27 where the handle 26 is formed, and the recess of the step portion 30 is used to form the engagement ring 18.

Therefore, in the case of such a bottle-like container, the middle portion in the height direction is bent, and the engagement ring 18 and the step formed on the bottom side of the barrel and below the handle 26 are stepped. The mouth portion 12 of the container body 10 is inserted into the portion between the portion 30 and the portion 30. As a result, the container body 10 is maintained in the folded state, and is not restored to the original shape shown in FIG. As a result, the weight reduction effect after disposal is enhanced, and the same operational effect as that of the first embodiment can be achieved.

Next, a fourth embodiment will be described with reference to FIGS. The overall shape of the container body 10 of this embodiment is similar to that of the second and third embodiments, and a step portion 27 is formed on a part of the outer peripheral side of the body, and the step portion 27 is formed. A handle 26 is connected to the upper part of the. Further, in this bottle-shaped container, a circular engaging recess 32 is formed on the bottom surface 17 as shown in FIGS. 13 and 14.

Therefore, when the container is thrown away after drinking the beverage filled therein, as shown in FIG. 15, the body portion of the container body 10 is bent so as to be rounded and the cap 13 is removed. The mouth portion 12, which is designed to be screwed, is inserted into the engagement concave portion 32 and engaged. Due to such an engaging recess 32, the container body 10
Will be maintained in a folded state as shown in FIG. 15, and will not be restored to its original shape after disposal. Therefore, even with such a configuration, it becomes possible to exert a high weight reduction effect after disposal.

The present invention has been described above with reference to the embodiments.
The present invention is not limited to a bottle-shaped container formed by blow molding a polyethylene resin, but can be applied to bottle-shaped containers made of various synthetic resins such as polypropylene resin. Also, the manufacturing method thereof does not necessarily have to be blow molding, and various other moldings such as vacuum molding or pressure molding may be used. Furthermore, if the body portion is foldable, it may be an injection molded container. Further, the shape is not limited to the shape of each of the above-described embodiments, and various changes can be made according to the mode of use and the type of liquid filled therein. Further, such a container may be used not only for a container for beverages but also for filling various kinds of liquid medicines and substances having fluidity.
