BACKGROUND OF THE INVENTION
The present invention relates to a self-supporting type packaging container.
[0002]
[Problems to be solved by the invention]
Traditionally, packaging containers that contain liquids, such as packaging containers that contain liquid detergents, shampoos, rinses, etc., have been formed into bottles by blow molding, etc. In the current situation, it is a molded product with a relatively large amount of synthetic resin used, and it becomes a bulky unnecessary product when it is empty and no longer used, and it is difficult to reduce waste. ing.
On the other hand, a pouch-type packaging container in which the periphery of the front sheet and the back sheet is bonded by heat sealing, and the bottom sheet by heat-sealing the periphery with the bottom sheet interposed between the front sheet and the back sheet Standing pouch-type packaging containers that are self-supporting by opening the door are also available. In this type of packaging container, the material used is also a sheet, which can be reduced in size by being folded at the time of disposal, which is advantageous in reducing waste. However, since this packaging container is cut out and opened, what is suitable as a container is food that is used up. When the above liquid detergent, shampoo, rinse, etc. are used as a container, It is a product for refilling into a container. Of course, it is conceivable to fill this packaging container with the required contents and provide it as a product for long-term use. There is an inconvenience that the shape is remarkably easily damaged, and it is difficult to reseal the sheet because the sheet is cut when taking out the contents. Therefore, it was unsuitable as a container for containing things to be used little by little.
In addition, the conventional blow-molded bottle or pouch-type container made of sheet material has restrictions and limitations on its shape, and it has become difficult to provide a container with a new design.
Accordingly, the present invention provides a packaging container that is easy to dispose by reducing the amount of material used in the packaging container, and that can be provided with a new design suitable for use in small quantities of the contents. With the goal.

[Means for Solving the Problems]
The present invention has been made in consideration of the above-mentioned problems, and is formed by recessing a sheet material, and has a lower end in a flange formed around an opening portion with a housing recess recessed in the depth direction from the front surface as the opening portion, The container main body is in contact with the bottom plate of the storage recess and is self-supporting, and a front sheet that closes the opening of the container main body, and the transparent sheet that opens to the front sheet at a position corresponding to the upper portion of the storage recess in the front sheet. the spout formed by covering with the check valve sheet hole from the container body side of the front seat is provided, characterized in that bonded to a peelable seal on the outer surface side of the front sheet so as to cover the spout packaging A container is provided to solve the above problems.
Then, in the present invention accommodating recess, as possible out to and are made tapered toward the top.

DETAILED DESCRIPTION OF THE INVENTION
It will be described in detail with reference now to the present invention from Figure 1 in the embodiment shown in FIG.
In the figure, reference numeral 1 denotes a packaging container. The packaging container 1 comprises a container body 2 and a front sheet 3 as shown in FIG. Is provided. And the said container main body 2 in this packaging container 1 is what the required part of the sheet | seat material was recessed by vacuum forming etc., and the front is made into the substantially triangular form in the depth direction as the substantially triangular open part 4. The housing recess 5 is tapered toward the top. A flange 6 is formed around the opening 4. In this storage recess 5, the depth distance from the front opening 4 is different between the upper part and the lower part of the storage recess 5, and the depth dimension on the lower side is larger (see FIG. 2). In this way, the depth of the lower side of the storage recess 5 is large, and the rear end 7a of the bottom plate 7 and the lower end 6a of the flange 6 connected to the front end of the bottom plate 7 in the storage recess 5 are grounded. And self-supporting form.
[0005]
On the other hand, the front sheet 3 has a substantially triangular shape corresponding to the shape of the container body 2 as viewed from the front. The front sheet 3 is superposed on the front side of the container body 2 and the periphery is welded to the flange 6 by heat sealing, ultrasonic welding or the like. By attaching the front sheet 3, a storage space that covers the storage recess 5 and is closed is formed. Further, as shown in the figure, the front sheet 3 has a seal 8 bonded to a position corresponding to the upper portion of the housing recess 5 so as to be peelable from the outside, and a position where the seal 8 is bonded. Is provided with a spout 9 in an unused state in which the contents placed in the storage recess 5 are not poured out, that is, in the distribution stage of the product containing the contents in the packaging container or the display stage in the store. It is protected by a seal 8 so that the spout 9 does not appear at the time.
As shown in FIG. 4, the spout 9 is formed by covering a through hole 10 opened in the front sheet 3 with a check valve sheet 11 from the back side (container body side) of the front sheet 3 as shown in FIG. A slit 12 is inserted into a portion of the check valve seat 11 that is exposed from the through hole 10. When the pressure in the storage space formed by the storage recess 5 and the front seat 3 is increased, the slit 12 is provided. Is provided to open. When pouring out the contents, after peeling off the seal 8 as shown in FIG. 3, the container is tilted forward so that the upper part of the container comes to the front, or the spout 9 is turned down. After the container moves to the 9 side, the container is poured out from the spout 9 by pushing lightly so as to crush the entire container. Note that the slit 12 of the check valve seat 11 is provided so that it does not open unless an excessive pressure is applied, and even if the packaging container 1 falls down with the seal 8 removed, the slit 9 can be removed from the spout 9. contained object is you are so as not to leak out.

【The invention's effect】
As described above, according to the packaging container of the present invention, the lower end of the flange formed around the open portion with the storage recess recessed from the front as the open portion and recessed in the depth direction according to the sheet material. The container body comprises a container body that is self-supporting with the bottom plate of the storage recess, and a front sheet that closes the open portion of the container body, and a spout is provided at a position corresponding to the upper portion of the storage recess. It is a feature. In this way, the packaging container has a simple structure consisting of a container body with a recessed portion by recessing the sheet material and a front sheet covering the recessed portion, so that the amount of material used as a container is small and the front sheet is peeled off when discarded. By making them separate, they are not bulky and are easy to dispose of. In addition, since the container body is formed by recessing the sheet material, it becomes possible not only to provide a new container with excellent design, but also to provide a certain degree of rigidity as a whole container. Even when used for a long period of time, it is difficult to lose shape and maintain its appearance. And since it is self-supporting, it is easy to use, and if various catchphrases are described on the front sheet, it becomes easy to stand out.
In addition, by forming the storage concave portion to be tapered upward, there is an advantage that the self-supporting stability of the entire container is enhanced and the contents can be easily poured out. Furthermore, if openable constituting the spout, as a container, such as a shampoo or rinse to be used out portionwise Note, etc. Luna such as more adaptive, in which excellent effects in practical use.
