DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a soft package used for enclosing a liquid or semi-solid container, and more particularly, to a container which can be easily taken out or squeezed out. The present invention relates to a soft package that can store stored items without leaking even if all of the stored items remain inside without being used up.

[0002]

2. Description of the Related Art For example, daily necessities such as liquid detergents, shampoos and rinses, foods such as mayonnaise, ketchup, miso, etc., and pharmaceuticals or quasi-drugs such as ointments and creams, A conventional soft package used for storing and storing a liquid or semi-solid material having a flow characteristic includes a bottomed container formed of a hard synthetic resin, a flexible container. Soft-bottomed or non-bottomed soft packages made of synthetic resin or thin foil sheets of aluminum foil, etc., or bags or boxes made of surface-treated paper etc. Many types are known.

[0003]

However, among the conventional storage containers, a rigid storage container having a bottom has to have a three-dimensional structure having a predetermined space capable of accommodating the contents.
In order to store and transport these in an empty state, a correspondingly large storage space is required, so that there is a problem that the efficiency of the storage space is extremely low, and at the same time, transport and transport while holding one by one. Alternatively, since it is stored and transported and transported in a container, the efficiency of the transporting and transporting operations is low, and an accident of falling and injuring the transporting and transporting operations has been caused.

Further, in order to take out the contents from these containers, it is necessary to equip a discharge device such as a pump or a hinge cap, and especially in the case of a rigid plastic container, There are problems such as the fact that when all the materials are used up, they become oversized garbage, and when they are incinerated, a relatively large amount of toxic gas is generated, and the high temperature may damage the incinerator itself.

[0005] On the other hand, a bottomed soft package made of a thin-film sheet is different from a bottomless soft package even when all of the contents are left inside without being used up. Although it can be prevented and the stored contents can be stored without leaking, there is a problem that its manufacture is very troublesome and relatively expensive.

[0006] The present invention has been made in view of such circumstances, and it is an object of the present invention to easily take out or squeeze out a stored item, and to make it self-standing even after opening. Further, a soft package that can be stored without leaking the stored contents even if all of the stored contents remain inside without being used up is provided by a simple structure.

[0007]

The gist of the means adopted by the present invention to solve the above-mentioned problems is as described in the above-mentioned claims.

[0008] By the way, in claim 1 described above, "...
One ridge extending upward from the bottom surface of the soft package body is inclined so as to protrude outward from the bottom surface. "Means that the ridge is linear and all ridges constituting the ridge are formed. It does not mean that the part is gradually inclined so as to protrude outward from the bottom surface, but it is obscure meaning that it is inclined so as to protrude outward from the bottom surface when observing the ridge side as a whole It is. The reason is that the flexible package is formed of a flexible thin film sheet, and thus can be bent or bent freely. Similarly, this soft package is a so-called soft package.
It does not always have a tetrahedral structure like a package called "Tetra Pak (trade name)", and is deformable.

According to the soft package of the present invention employing such a configuration, the top facing the bottom is displaced outward from the bottom, and the top serves as an outlet for taking out the contents. From here, when tilting while supporting the whole or when the peripheral wall is pressed inward as needed,
It is possible to reliably take out or squeeze out the necessary amount of the stored contents without polluting the surroundings.

[0010] Then, when the necessary amount of the stored material is reliably taken out or squeezed out, if there is any remaining material that has not been used up, air is taken in from the outlet provided at the top to the inside, and the soft peripheral wall is taken out. Bulges outward,
Together, these can move the contents inside to the bottom side. In other words, even after opening, the container can be made to stand on its own, the remaining contents that have not been used up can be stored without leaking, and the contents can be divided and used.

Further, since the flexible package is made of a flexible sheet material, the flexible package can be bent at a position below the top and above the stored material that has not been used up and can be taken in. The effect that the mouth can be sealed is obtained.

When all the contents have been used, the amount of the synthetic resin used to form the soft package is small, so that it may become oversized garbage or be incinerated as in the conventional case. An effect is obtained that inconvenience such as generation of a large amount of toxic gas or damage to the incinerator itself due to high temperature is unlikely to occur.

Next, a second aspect of the present invention adopts such a configuration.
According to the soft package described in (1), in addition to the function of the soft package according to claim 1, the flange formed by heat sealing both ends of the thin film sheet in the longitudinal direction functions as a skeleton and a handle. Will be able to function as

Next, a third aspect of the present invention will be described.
According to the soft package described in (1), substantially the same function as the function of the soft package according to claim 1 or 2 can be obtained.

[0015] That is, with a simple structure, it is easy to take out or squeeze out the contents, and even after opening, the contents can be made independent. Even if all the contents remain inside without being used up, It is possible to provide a soft package that can store contents without leaking.

[0016]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described in more detail with reference to more specific examples shown in the drawings.
The present invention is not limited by the following examples unless it exceeds the gist of the present invention.

FIG. 1 is a perspective view schematically showing the entirety of a soft package 10 according to the present invention, in which an outlet for taking out the contents is not opened. FIG. 2 is a longitudinal sectional view taken along the line AA of FIG. 1, and FIG. 3 is a soft package 1 shown in FIG.
FIG. 7 is a front view shown for explaining one state when manufacturing No. 0;

In the figure, a soft package 10 is a cylindrical body 11 formed by heat sealing both ends of a polypropylene sheet having a thickness of about 0.1 mm and a width of 34 cm in the longitudinal direction.
Is heat-sealed with a heat-sealing machine so that the width of the welding surface 16 is about 1 cm to form a ridge 12 inclined 30 degrees or more (FIG. 2). 11a is filled with about 6500 ml of a commercially available viscous cleaning agent, and then the width of the welding surface 16 is about 1 cm so that the width of the heat sealing surface is about 1 cm above the ridge 12. As described above, when the ridge 13 is formed by heat sealing in the horizontal direction with a heat sealing machine, and the ridge 13 is thermally cut off from the cylindrical body 11, the soft package 10 as a final product is obtained. It is preferable to form the ridge 11 provided on the soft package 10 manufactured at the same time when the soft package 10 is cut off, because the workability can be improved. Substantially, these steps are repeatedly performed.

In the flexible package as the final product, the edge 12
May be provided so as to protrude outward, and the inclination angle of the ridge 12 is not limited to 30 degrees or more, and is appropriately designed according to the dimensions and shape of the flexible package as the final product. In the case of the flexible package as the final product, the bottom and ridge 1
2 is preferably an obtuse angle of 140 degrees or less, and more preferably an obtuse angle of 95 to 120 degrees.

That is, the soft package 10 is characterized in that the ridge 12 extending upward from the bottom surface of the soft package 10 is inclined so as to protrude outward from the bottom surface. An outlet 15a is formed by cutting off a part of the top portion 15 facing the bottom surface with scissors or the like, so that the internal contents can be taken out or squeezed out from the outlet 15a.

As shown in the figure, an outlet having a cover for covering the opening can be formed integrally with the top portion 15 in advance. This embodiment particularly corresponds to the third aspect of the present invention.

Next, a procedure for taking out the stored contents from the flexible package 10 will be described.

First, a part of the top portion 15 facing the bottom surface is cut off with scissors or the like to open an outlet 15a.
Then, the whole is lifted up by hand, and the outlet 15a is moved above the opening of the container into which the contents are to be transferred, so that the contents are slowly poured or squeezed out by hand. 4).

At this time, an outlet 15 formed in the top 15
a protrudes like a spout of a kettle, and furthermore, an apparent guideway (not shown) is formed in the vicinity of the center of the bottom surface, which hangs downward particularly by the weight of the storage object and leads to the outlet 15a. Since the action of collecting and guiding the articles toward the outlet 15a is added, it is possible to reliably take out the contents without contaminating the surroundings, and to take out or squeeze out the contents to the end without waste and remove all of them. The effect of being able to use up is obtained.

[0025] Further, after a desired amount of stored material is taken out, if there is any remaining material that has not been used up,
Air can enter the inside from the outlet 15a opened at the top 15 to move the contents to the bottom side. Further, since the soft package 10 is a flexible peripheral wall, it bulges outward. The container can be moved further to the bottom side, and together, since the center of gravity moves downward, it can stand alone even after opening (FIG. 5), and the remaining container that has not been used up can be removed. The effect of being able to store without leaking, and to be able to take out or squeeze out while dividing the contents is obtained.

Further, since the flexible package is made of a flexible sheet material, it is naturally bent at a position below the top portion 15 and above the remaining contents, thereby sealing the intake port 15a. The operation and effect can be obtained.

When all the contents are taken out, since the soft package is formed of the thin film sheet, it does not become oversized garbage, and the safer disposal can be achieved. .

A cylindrical body 11 having a flange 14 formed by heat sealing both ends of a thin film sheet in the longitudinal direction.
When the flange 14 is connected to the top portion 15 facing the bottom surface by using the flange, the flange 14 functions as a skeleton together with another heat-sealed welding surface 16. This prevents the entire body from shrinking and becoming sloppy, and also functions as a handle when carrying or carrying.

[0029]

As described above, according to the flexible package of the present invention, in particular, it is easy to take out or squeeze out the contents, and it is possible to stand alone even after opening. In terms of being able to provide a soft package that can be stored without leaking even if all of the contents remain inside without being used up, it is extremely effective in that it can be provided with a simple structure and at low cost. Things.
