DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a simple disposable container made of synthetic resin which can be easily crushed and disposed of.

[0002]

2. Description of the Related Art In recent years, used containers have been separated and collected and provided for reuse. However, there is a limit to the processing, and many containers are still discarded as they are without being crushed. Now, how to do this is a serious problem. In view of the problem of trash in such containers, recently, bag containers called so-called pouches have become available as simple containers or refill containers. This type of bag container is excellent in that it can be considerably reduced in size by folding, crushing, etc. at the time of disposal, and the amount can be significantly reduced.

[0003]

However, on the other hand, since this kind of bag container has no shape-retaining property and is difficult to determine its shape, it is difficult to use, handle or look at the following. It has many disadvantages as well. The filling of the contents is not easy and the filling speed is extremely slow. It is difficult to stand up, and even if it is of a stand-up type, it tends to fall as the contents are reduced. It is difficult to hold because there is no gripping means, it is difficult to determine the pouring direction, it is hard to pour, and it is not easy to handle and easy to leak. In the case where contents are poured out halfway and the remaining amount is stored, the contents often fall down, leaking the contents, and polluting the surroundings. In particular, in a refill container in which the mouth is cut open, it cannot be closed sufficiently, so that it is almost impossible to prevent leakage. It looks bad. Therefore, the present invention aims to solve all of the problems by making it possible to easily perform the function of a bottle while easily crushing and discarding.

[0004]

In order to achieve the above object, a first aspect of the present invention is to provide a bottle-shaped thin-walled container body 1 having a relatively large cylindrical filling port 3 at the upper end of a body 2 by blow molding. The filling port 3 formed and filled with the contents is sealed 4, and a relatively small spout 5 which is closed so as to be able to be cut and opened with the sealing is secondarily formed. Is provided with a stopper 6 which is detachably fitted to the cutout opening 5.

According to a second aspect of the present invention, there is provided a simple disposable container made of a synthetic resin according to the first aspect, which is easy to crush and dispose. A plug support piece 8 is arranged in the plug storage recess, and a plug support hole 9 is formed in the plug support piece, and the plug 6 is detachably fitted into the plug support hole. Be supported.

According to a third aspect of the present invention, there is provided a simple disposable container made of a synthetic resin according to the second aspect, which is easily crushed and discarded. The plug 6 is connected to the end of the band.

In the figure, 1 is a bottle-shaped thin container body blow-molded with a polyolefin-based synthetic resin or the like, 2 is a box-shaped body of the container body, 3 is a relatively large cylinder protruding from the upper end of the body. In the filling port (Fig. 3)
After filling the contents, the filling port is crushed from both sides by heat fusing means, ultrasonic fusing means or the like, and fusion sealed 4 (FIG. 1). Reference numeral 5 denotes a relatively small cylindrical spout which can be cut and formed secondarily at the filling port 3 in association with the sealing 4, and 6 is detachably fitted to the spout 5 which has been cut and opened. This is a plug attached to the container 1 as an accessory. In FIG. 1, a dotted line 13 indicates a cutting portion for cutting and opening the spout 5, and when making the opening, the cutting portion may be cut with scissors or the like. In addition, a thin break line or the like that breaks the cut portion 13 by twisting the cut portion 13 may be used.

[0008] The container body 1 has a recessed stepped housing recess 7 formed in the upper part of the body 2 on the rear surface, and a stopper supporting piece 8 is erected in the center of the recessed housing body. A plug support hole 9 is drilled in the lower part of the body support piece, and the plug 6 is removably fitted and supported in the plug support hole. A through hole 11 for band connection is provided. Although the thickness of the container body 1 formed by the blow molding described above may be as thin as 1 mm or less, the container body 1 has appropriate rigidity such that the container body 1 can naturally maintain its shape.

The strip 10 has a projection 12 at the base end and a plug 6 at the tip.
Are formed integrally by injection molding using the same synthetic resin as the container body 1, and the protrusion 12 is fitted into the through-hole 11, so that the base end is connected to the plug support piece 8. Connect. The connection may be made before or after the cutting opening of the spout 5.

[0010] When filling the contents, the contents may be filled in the same manner as the bottle with the filling port 3 shown in FIG. 3 being opened. After the filling, as shown in FIG. 1, the filling port 3 is crushed from both sides by a heat fusing means, an ultrasonic fusing means or the like, and is fused and sealed. Is formed secondarily.

Next, when pouring out the contents, the spout 5
Is cut and opened by the cutting section 13 and poured out from the spout. At this time, the body 2 may be pressed. When the contents remain after pouring and are to be preserved, the container 1 is erected in the same manner as a bottle, the plug 6 is removed from the plug support hole 9, and as shown in FIG. To fit, save,
store. In the subsequent pouring, the plug 6 may be pulled out and poured out from the pouring port 5 in each case. The pulled-out plug 6 is held in the container 1 via the narrow band 10.

FIG. 4 shows another embodiment of the invention of a simple disposable container made of synthetic resin which can be easily crushed and discarded according to the first and second aspects. In this case, in FIGS. 1 to 3, the plug 6 forms a single body, and does not connect the strip 10 and the protrusion 12. Therefore, it does not have the through hole 11 for fitting the projection to the plug support piece 8. Others are the same as those in FIGS. 1 to 3.
