Description

[Detailed description of the invention] [Industrial field of application] This invention relates to a structure for taking out contents of a packaging container.

[Conventional technology] Standing and packaging containers for youth products, etc.
Pouches and paper containers are used. As shown in FIGS. 1 and 2, conventional standing pouches have a cylindrical shape with a front piece 2, a back piece 3, and a bottom piece 4, and are used to store fluids and powdery objects. They are often stored, displayed, and displayed in three-dimensional shapes. How to remove the contents from the pouch:
There is a method of tearing the pouch open using the notch 5 and using a straw or the like.

[Problems to be solved by the invention] However, this tearing requires a considerable amount of force, making it difficult for young children to open the opening, and the contents often spill out due to vibrations during tearing. Therefore, it has been considered to previously form a hole in the pouch for inserting a straw, but in this case there are many problems in achieving both the ability to retain the contents and the ease of operation. The same applies to holes for inserting straws in paper containers. Especially standing
In the case of pouches, it is important to note that when the pouch material is a laminate material, when the laminate material is punched out to form a hole for inserting a straw, adhesive and ink may leak from the edge of the punched laminate material. Alternatively, since the cut edges of the Al foil are exposed, it is necessary to develop a technology to prevent them from coming into contact with the contents. We have not yet obtained the required standing pouches and paper containers. As a solution to this problem, the applicant of this application previously proposed an improved method for manufacturing a standing pouch with a hole for inserting a straw (see Patent Application No. 17837 of 1982), and achieved remarkable results. However, there is still a risk that the contents may blow out when the tab is peeled off to open the hole for inserting the straw, and improvements in this respect have been desired.

This invention was made in view of the above circumstances, and it is possible to easily and reliably achieve both content retention performance and operability. The contents of the packaging container can easily cover the adhesive, ink, and Al foil cut edges that are exposed when forming the container, and there is no risk of the contents blowing out when the hole for inserting the straw is opened. The purpose of this invention is to provide a structure for taking out items.

[Means for Solving the Problems] Corresponding to this object, the contents removal part structure of the packaging container of this invention includes a hole for inserting a straw formed through the front and back of the body member, and a hole for inserting a straw into the body member. a first inner lining material that is affixed to the body member from the back side of the body member to close the hole for inserting the straw; and a hole for inserting the straw in the body member or the first inner lining material from the back side of the body member. a second inner liner material that covers the first inner liner material by adhering it to a part that is not covered by the straw; and a second inner liner material that is placed on the front side of the body member so as to cover the hole for inserting the straw, and that is inserted through the hole for inserting the straw. A structure for taking out contents of a packaging container, comprising the first inner liner material and an adhesive tab material, wherein the second inner liner material is different in material or thickness from the first inner liner material. By making the difference, the strength is lower than that of the first inner adhesive material, and it is configured to be breakable by inserting a straw, and at least in the portion that spans the hole for inserting the straw, it is different from the first inner adhesive material. It is characterized in that it is configured so that there is a gap between it and the second inner lining material.

[Operation] When taking out the contents, when the tab 21 is picked up and peeled off from the front piece, the first inner lining material 17 adhered to the tab 21 is destroyed along with the tab, and the straw insertion part is removed. A hole opens. Next, insert a straw into the straw insertion hole, pierce the second inner patch, insert it inside, and suck out the contents.

[Example] The details of this invention will be explained below with reference to the drawings showing an example.

In Figures 3 and 4, 11 is a standing pouch, and standing pouch 1
1 consists of a substantially rectangular front piece 12, a substantially rectangular back piece 13, and a substantially circular bottom piece 14, and the front piece 12 and the back piece 13 are adhesively sealed at the upper end and left and right side ends of each. , and the lower ends of the front piece 12 and the back piece 13 are adhesively sealed to the circumferential end of the bottom piece 14 to form a container body. A content removal portion 1 is provided on the front piece 12 of the container body.
5 is formed. Front piece 12, back piece 13,
As the material constituting the bottom piece 14, commercially available pouch materials may be used.

Details of the contents removal section 15 are as shown in FIG. 5a. That is, the front piece 12 has a hole 16 for inserting a straw that passes through its front and back sides, and a hole 16 for inserting a straw is formed on the back side of the front piece 12.
A first inner adhesive material 17 covering the straw insertion hole 16 is adhered to cover the straw insertion hole 16. First inner patch material 17
are constructed from materials such as polypropylene, polyethylene, and ethylene-vinyl acetate copolymers.

Furthermore, a second inner adhesive material 18 is adhered to the back side of the front piece 12, covering the first inner adhesive material 17. This second
The inner adhesive material 18 is also made of polypropylene, polyethylene,
It is made of a material such as ethylene-vinyl acetate copolymer, but it is important that it has a structure that is strong enough to be easily destroyed by being pierced with a straw. This strength can be achieved by appropriately selecting the following. The second inner lining material 18 is adhered to the inner surface material of the front piece 12 at the peripheral portion 20, and the first inner lining material 17 is not in close contact with the second inner lining material 18, but is attached to the periphery of the hole 16. Some gap 22 is left in section 17a.

Further, a tab 21 covering the straw insertion hole 16 is located on the front side of the front piece 12, and is adhered to the first inner lining material 17 through the straw insertion hole 16.

In the contents removal section structure of the packaging container configured in this way, when the contents are taken out, when the tab 21 is picked up and peeled off from the front piece 12, the first inner adhesive material adhered to the tab 21 is removed. 17 is destroyed along with the tab 21, and the hole 1 for inserting the straw is
6 opens (Fig. 5b). However, the straw insertion hole 16 is still covered with the second inner liner 18, and the packaging container 11 is sealed. Therefore, as shown in FIG. 10, a straw 23 is pierced into the second inner patch material 18 and inserted into the interior to suck out the contents.

[Effects of the invention] As described above, the structure of the contents removal portion of this packaging container has extremely good operability when taking out the contents.

Even when the tab 21 is pulled to open the hole for inserting the straw, the packaging container 11 is still completely sealed by the second inner liner 18, so the stronger first inner liner is used. There is no blowing out of the contents upon removal, and the second inner adhesive material can be easily destroyed by being pierced with a straw, so the contents may not be blown out when the second inner adhesive material is pierced with a straw. Therefore, blowing out when taking out the contents can be completely prevented. In particular, when piercing a straw, since there is a gap 22 between the hole 16 and the second inner liner 18, even if the tip of the straw to be inserted slips, it will not deviate from the hole 16 and the operation can be performed. It is easy and can be operated even by young children.
In addition, during storage or display, the hole 16 for inserting the straw is triple-blocked with the first inner lining material 17, the second inner lining material 18, and the tab 21, resulting in excellent strength and very good retention performance for the contents. Therefore, it is possible to easily and reliably achieve both content retention performance and operability. Moreover, the inner lining material 17 can reliably cover the adhesive, ink, and Al foil cut edge that are exposed when a hole for inserting a straw is formed by punching out the original laminate.

In the above embodiment, the peripheral part 20 of the second inner adhesive material 18 was adhered to the front piece 12, but it may be adhered not to the front piece 12 but to the peripheral part 17b of the first inner adhesive material 17. However, in this case as well, the peripheral edge 1 of the hole 16
7a, and the peripheral edge 17a of the hole 16 and the second
A gap 22 is formed between the inner adhesive material 18 and the inner adhesive material 18.
