BACKGROUND OF THE INVENTION
The present invention relates to a simple disposable container made of synthetic resin that can be easily crushed and discarded.
[0002]
[Prior art]
In recent years, used containers have been collected separately and reused, but there are limits to processing, and many things are still discarded without being crushed. Yes, how to do this is a serious problem.
In view of the dust problem of such containers, recently, a so-called pouch as a mere container or a refill container has come into circulation. This type of bag container is excellent in that it can be considerably reduced by folding, crushing, or the like at the time of disposal, and the amount can be remarkably reduced.
[0003]
[Problems to be solved by the invention]
On the other hand, this type of bag container has no shape retention, and it is difficult to determine its shape. Therefore, it has many disadvantages in terms of use, handling, and appearance. is doing.
(1) The filling of the contents is not easy and the filling speed is very slow.
{Circle around (2)} It is difficult to stand up, and even a stand-up type tends to fall down as the content decreases.
(3) It is difficult to hold because it does not have a gripping means, it is difficult to pour because the pouring direction is difficult to determine, and handling is not easy and it is easy to leak.
(4) When the contents are poured out halfway and the remaining amount is stored, the contents often fall down and the contents leak, and the surrounding area is often stained. In particular, in a refillable container that opens the mouth, it is impossible to prevent the leakage because it cannot be sufficiently closed.
▲ 5 ▼ It looks bad.
Therefore, the present invention is intended to solve all of these problems by facilitating crushing and discarding and also making it possible to sufficiently exhibit the function of the bottle.

DETAILED DESCRIPTION OF THE INVENTION
The drawings show an embodiment of the invention of a simple disposable container made of a synthetic resin that can be easily crushed and discarded according to claims 1 to 3.
In the figure, 1 is a thin, easily deformable bottle-shaped container formed of a polyolefin-based synthetic resin or the like, 2 is a box-shaped cylinder of the container, and 3 is a cylinder provided at the upper end of the cylinder The filling port is used exclusively for filling, and after filling, it is crushed into a single shape and fused and sealed. Reference numeral 4 denotes a small tubular spout provided on the inclined shoulder 5 of the container body, which is used only for pouring and is opened by cutting (cutting) the tip.
[0008]
The container body 1 is formed by appropriately forming the dish-like front half 1a and the latter half 1b of the body 2 through the filling port 3 from a polyolefin synthetic resin film or sheet, such as vacuum molding, pressure molding, match forming, or the like. Are formed into a thin container with a wall thickness of 1 mm or less, and the front half 1a and the latter half 1b are respectively provided with flanges 6 on the periphery, and are mutually connected. Are formed in a state where they are connected on one side and expanded to the left and right (FIG. 2), and then folded, the flanges 6 are brought into contact with each other, and are fused and integrated by ultrasonic welding means or the like.
In addition, the spout 4 is arranged to protrude forward or backward in a small cylindrical shape at one or both of the inclined shoulders 5 of the front half 1a and the rear half 1b. In the illustrated example, it is provided only in the first half 1a, but is not limited thereto. In addition, it may be provided so as to be shifted to either the left or right side.
[0009]
Since it is the above structure, what is necessary is just to fill the content like the bottle with the opening filling port 3 in the bottle form of FIG. 3 thru | or FIG. At this time, the flange 6 fused and integrated with each other serves as a rib, and is necessary for naturally maintaining the shape of the filling port 3 by itself in the form and the synthetic resin molding. Since it can be made thick, it does not interfere with filling.
After filling, as shown in FIG. 1, the filling port 3 is crushed into a single shape by ultrasonic welding means or the like to be fused and sealed 7. Thereafter, the filling port 3 is not opened.
When the contents are to be poured out, the tip of the spout 4 is opened by cutting, and the spout is poured out only from the spout. The spout 4 can be formed with a thin tip at its shape, molding, and easy to cut. Further, when pouring out by the spout 4, it is almost in a state of being poured out directly from the barrel 2, and it is sufficient to pour in a state where the barrel 2, and thus the container body 1 is lying down, and it is necessary to invert it. Absent.
When the contents remain after pouring and are to be stored, the spout 4 is closed with a stopper or the like, and the bag container body 1 is laid down with the spout 4 facing upward and stored and stored.
[0010]
【The invention's effect】
According to the first, second, and third aspects of the invention, the following effects can be obtained because of the configuration described above.
(1) Even if the container body 1 is a bottle shape, it is thin and easy to deform, so it can be easily crushed and folded at the time of disposal, and can be considerably reduced in size. Can be reduced.
(2) The barrel 2 for containing the contents is box-shaped, and a cylindrical filling port 3 is provided from the upper end of the barrel to be used only for filling the contents and sealed after filling, thereby forming a bottle-shaped container body. 1 is formed, the container body 1 can be filled with the same contents as a bottle, and even if it is a bag container, it can be filled at a high speed, and the filling port 3 can be easily sealed. It can be done quickly.
(3) Since the barrel 2 is box-shaped, the container body 1 after filling the contents can be handled in the same manner as a box in the lying state, and can be stored and stored stably. Moreover, it can be stored and stored in a sealed state by sealing the filling port 3.
(4) Since the spout 4 that is cut and opened exclusively for pouring is positioned at the appropriate position of the box-shaped body 2 with the container 1 lying down, the contents should be poured out. The pouring outlet 4 may be opened by being cut open, and at the time of the pouring, the container body 1 can be directly poured out from the trunk 2 in a state where the container body 1 is laid down, and the container body 1 is inverted. Therefore, there is no need to change the pouring direction due to unexpected bending or the like, and the fluctuation does not make it difficult to pour.
(5) Since the barrel 2 is box-shaped, it is easy to hold, easy to pour with a fixed pouring direction, easy to handle, and less likely to leak.
(6) Even when the contents are poured out halfway and the remaining amount is preserved, the barrel 2 is box-shaped, and can be stably stored and stored with the spout 4 facing upward when the container body 1 is lying down. The contents will not leak and will not stain the surroundings. Therefore, the spout 4 can be simply closed with a stopper or the like.
(7) It looks the same as the bottle, so it looks good.
(8) Due to its structure, the first half 1a and the second half 1b can be easily molded by synthetic resin vacuum molding, pressure molding, match forming, etc., and these can be easily joined and integrated. Can be manufactured very easily and can be provided at low cost.
