2. Description of the Related Art As a conventional self-supporting package, a rectangular one having a bottom end and an upper end having the same width as shown in FIG. 4 is generally widely used, but a liquid content is poured out from the upper end. At that time, there was a problem in handling at the time of use, such that the upper end was caught in the container to be transferred, the container was tumbled, and the liquid inside was spilled. Also, when a large amount of liquid is put in, it cannot be said that the stability and shape retention of the package are excellent, and when the contents are poured out, the body of the package does not have the weight of the contents. It bent properly and could not be dispensed well.

In order to deal with these problems, there has been proposed a package having a shape in which the spout has a protruding shape, a shape having an opening at the upper end, and the like. However, when the contents of these packages increase and the weight increases, the stability of the packages deteriorates and various problems occur such as being difficult to hold.
Especially in the case of an intestinal cleansing agent whose content is a medicine, 2 l
It is necessary to dissolve a large amount of water inside the package, and the powder and liquid do not mix well inside the package and it is difficult to dissolve, or when transferring to a cup the upper end is difficult to pour into the container etc. There was a problem.

[0004] It is already known that powder formulations such as intestinal cleansing agents filled in self-supporting packages are dissolved in water each time they are used, but these formulations have a large volume and are determined. It is necessary to divide the dose into several doses, to improve the stability and solubility of the package, to improve the ease of pouring from the package into a container, and to reduce the volume attached to the package. It was desired to improve the accuracy of the scale.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems of the prior art, and its purpose is to make it possible to pour a liquid content without disturbing the package itself. Now, even if it contains a large amount of liquid, stability and shape retention that does not cause problems such as center folding, shape that easily causes convection to facilitate dissolution when mixing powder and liquid in the package. , To provide a self-supporting packaging with the accuracy of the measured values when calibrated, and to re-seal to allow dissolution of the contents and pouring of the contents in multiple batches. It is to provide a self-supporting package having a possible spout.

Further, in a preferred embodiment of the self-supporting package of the present invention, the volume of the self-supporting package is 500 to 3000 ml, and the scale has a scale that allows confirmation of the internal volume.

[0009]

BEST MODE FOR CARRYING OUT THE INVENTION The self-supporting package of the present invention will be specifically described below, but the present invention is not limited thereto.

FIG. 1 shows an example of the self-supporting package of the present invention in a flat state. As is clear from FIG.
The self-supporting package of the present invention is formed of a bottom face forming part 1 and a pair of side face forming parts 2 joined to the bottom face forming part 1 and facing each other, and the pair of side face forming parts 2 is an upper end part 3 and a side end part 4. Are joined and sealed together. In the self-supporting package of the present invention, the contents can be filled in the internal space formed by the bottom face forming part 1 and the pair of side face forming parts 2, and the bottom face forming part is filled in the self-supporting state in which the internal space is expanded. The cross-sectional area in the lateral direction is the same or gradually decreases from 1 toward the upper side of the pair of side surface constituting portions 2.

In the self-supporting package of the present invention, in the flat state, the ratio of the lengths of the sides of the upper end portion 3 and the bottom end portion 5 is 0.15.
.About.0.65: 1.0 is required. If the ratio of the side lengths is less than the above value, it is not possible to make a sufficiently large mouth portion on the upper end portion 3, while if it exceeds the above value, the large upper end portion 3 of the package interferes with the container to be poured out. Or, when it contains a large amount of liquid, it is not preferable because it may be broken inside. In this way, by controlling the ratio of the length of the side of the upper end portion 3 to the length of the side of the bottom end portion 5 within a certain range, the ease of pouring the liquid contents, the stability of the package, and the shape retaining property are preferably achieved. To be done.

Further, in the self-supporting package of the present invention, the upper end portion 3
It is necessary that a resealable spout 6 be provided in the. The spout 6 is suitable as a mouth for pouring liquid or pouring the contents into the self-supporting package, and the position of the spout is at the upper end 3 of the package in terms of ease of pouring into the container.
In particular, it is preferable to provide it at the center of the upper end portion 3. It is also possible to form the upper end 3 substantially only from the resealable spout as in the self-supporting package of FIG. Spout 6
There is no particular limitation on the structure of the structure as long as it can be resealed, and a conventionally known structure such as a structure having a screw cap as a cover or a structure having an inner cover for improving sealing performance can be used. . The inner diameter of the spout is generally 16 mmφ, but it is preferable to make it 20 mmφ or more for the contents that need to be dissolved before use in order to make it easier to add dilution water such as tap water.

The width of the self-supporting package of the present invention is 1 / the height from the side of the bottom end 5 to the side of the upper end 3 in a flat state.
1 to 3 of the length of the side of the bottom end 5 at the position A of 3 to 2/3
It is 1.1 times, and it is preferable to gradually decrease symmetrically from the position A to the side of the upper end portion 3. That is, when the side surface of the self-supporting package is flat, it is formed so that the width from the side of the bottom end portion 5 to the height of the position A is vertically or symmetrically widened in the lateral direction, and goes above the position A. It is preferable that the width be gradually narrowed symmetrically toward the upper end. The position A is 50% of the height of the self-supporting package ±
More preferably, it is 10%. By forming a self-supporting package in this way, the stability of the package at the time of self-supporting is increased, and when the liquid content is moved from the upper end to the bottom end and from the bottom end to the upper end, the contents are mixed. It is possible to cause convection of the liquid on the side surface to facilitate stirring.

As shown in FIGS. 2 and 3, the self-supporting package of the present invention is 1/3 of the height from the side of the bottom end 5 to the side of the upper end 3.
At a position A of ⅔, a part of the joint sealing of the side end portion 4 extends symmetrically to the inside and the surplus joint sealing surplus portion 7 is formed.
Is preferably provided. Further, it is preferable that the joint sealing surplus portion 7 extends symmetrically inward in the range of less than 10% of the width of the self-supporting package. By doing so, when the liquid is agitated inside the package, the liquid inside has a swirling effect, and when the liquid is filled in the part, the package bends slightly and the package shape is always constant. Can be kept at. further,
In this way, since the package is always kept in a constant shape, the accuracy of the scale attached to the package can be increased.

The self-supporting package of the present invention is formed of a bottom face part and a side face part, and the materials of these parts are preferably flexible enough to be easily folded when discarded, for example, Polyolefin such as polypropylene or polyethylene, nylon, polyethylene terephthalate, single layer or laminated plastic film such as EVOH, and laminated plastic film using aluminum or titanium dioxide or paper as the inner layer and outer layer of any of the above films can do. Generally, when filling a material that needs light shielding, a light-shielding material is selected, and when filling a material that is feared to be changed by oxygen, a material that does not have oxygen permeability is selected.
When it is necessary to check the properties and quantity, transparent materials are selected.

Further, the self-supporting package of the present invention can be printed, and, for example, a scale capable of confirming the content can be attached to the side surface constituting portion. When it is necessary to measure the content to some extent accurately, it is preferable that a part of the joint sealing at the side end of the package extends symmetrically inward. The volume of the self-supporting package of the present invention is not particularly limited, but preferably 500 to 3000 ml, more preferably 700 to 2500 ml, and still more preferably 10 ml.
It is from 00 to 2500 ml. In the case of low volume, it is light, so problems such as spilling when transferring contents by hand are unlikely to occur, but in the case of high capacity of 500 ml or more, and even 1000 ml or more, the whole becomes heavy and the contents are transferred by hand There is a high possibility of spilling. Especially in the case of intestinal cleansing agents that are taken during colon surgery, colonoscopy, etc., about 2
Since 000 ml of the aqueous solution is divided into a plurality of cups and transferred and consumed for drinking, there is a problem such as water spilling from the cup when transferring, and improvement from the medical field has been demanded. However, the self-supporting package of the present invention does not cause a problem even when it is filled with such a high volume content.

The content to be filled in the self-supporting package of the present invention may be any of liquid, solid, powder, gel, sol, etc., but is not particularly limited, but in order to make the best use of the features of the present invention, it is necessary to use it. It is preferable to fill the contents (for example, powder) to be used by dissolving or diluting with a liquid. Specifically, foods such as concentrated liquid foods and orally administered medicines such as intestinal cleansing agents can be filled. In the case of a concentrated liquid food, it is difficult to take it home with a liquid when it is eaten by a patient at home because of its weight, but at home, a powder or solid liquid food is dissolved in water when used. Used for use. In the case of an intestinal cleansing agent, 20 in the package.
It is used in such a manner that it is dissolved in a large amount of water of about 00 ml at the time of use, and the solution is transferred to a container such as a cup for oral administration.

The self-supporting package of the present invention can be manufactured by appropriately using any conventionally known method. For example, a self-supporting bag making machine makes a desired bottom shape and a pair of side surface parts. Create a three-sided self-supporting package consisting of, insert a resealable spout into the upper end of this package, and use a high temperature heat plate from the outside to the top and side edges of a pair of side components It can be manufactured by applying pressure to and sealing.
