Description

[Detailed description of the invention] [Field of industrial application] The present invention is a method for securing the lid and the main container when a lid is placed over the product removal opening of the main container in packaging containers such as styrofoam boxes and envelopes. Regarding sealing structure.

[Conventional technology]

Currently, there are packaging containers such as styrofoam boxes for storing products, as shown in FIG.

In the figure, 1 is a main container made of styrofoam, and 2 is a lid made of styrofoam, which is used to store pickles and other local products at tourist spots and sell them as souvenirs. Then, a handbag 3 is attached to make it easy to hold, and this handbag 3 uses a nylon string.

Since it is impossible to form the packaging container integrally with the handbag, a string locking portion is formed on the container side and the end of the string is tied thereto. In the illustrated example,
A protrusion 4 having a through hole is formed on the side of the main container 1, and the end of the handbag 3 is passed through the protrusion 4 from above, and the lower protruding end is tied to form a knot 3a to prevent it from slipping out.

Further, the lid 2 is integrally formed with a ring 5 on the side thereof, and the handbag 3 is passed halfway through this portion, so that the lid 2 can be opened and closed along the handbag 3.

Furthermore, in order to prevent the lid 2 from being opened freely during store display, the seal may be sealed by wrapping a paper band 6 around the entire product. , company name, and other advertising characters and designs can be printed.

Note that as a sealing method, the joint between the lid 2 and the main container 1 may be taped from the outside.

On the other hand, as shown in FIGS. 6 and 7, the envelope 7 for documents is sealed using a folding flap 8 as a lid by gluing or stringing it.

In the case of FIG. 6, a release paper 10 is pasted on the adhesive coated surface, and upon use, this is peeled off and the flap 8 is pasted.
Moreover, in the case of FIG. 7, the string 9 is wound.

[Problem to be solved by the invention] In the case of the box-shaped packaging container with a lid shown in FIG. Moreover, the work of attaching the handbag 3 is time-consuming, such as making the knot 3a. Further, the lid 2 and the main container 1 must be sealed with a band 6 or the like separately from the attachment of the handbag 3.

In the case of the envelope 7 shown in Figures 6 and 7, gluing the flap 8, which is the lid, is easy due to its shape;
When carrying a large number of such envelopes 7 in a bundle, it is difficult to hold them in the hand as they are, and the envelopes located inside may fall out.

The purpose of the present invention is to eliminate the disadvantages of the conventional example,
We have created a sealing structure for packaging containers, etc. that can be easily sealed regardless of their shape, such as boxes or envelopes, and can be attached to a handbag at the same time as the seal.It is also strong enough to hang even heavy items. It is about providing.

[Means to solve the problem]

In order to achieve the above-mentioned object, the present invention provides a packaging container that covers the product removal opening of the main container.
After putting a lid on the main container, attach a tape-like base paper made of a synthetic resin low-foam foam to the joint part as a sealing paper, with one end of the handbag pre-glued. It is a synthetic paper using an oriented film (OPP) formed by an axially oriented film forming method, and is coated with a synthetic resin adhesive as an adhesive. The gist is that the ends are overlapped on the surface, the vicinity of the ends rises approximately in parallel, and the upper end is curled and continuous.

[Effect]

According to the present invention, after putting a lid on the main container, the joint part is sealed with a sealing paper, but since the end of the handle is glued to the sealing paper in advance, the sealing paper is The handpiece can be attached to the container using paper as a base paper, and there is no need to form a special locking part for the handpiece.

In addition, the handbag is made of synthetic resin low foam material, so it is strong and has plasticity, making it easy to fit in your hand.The handbag is also made of tape, so if you attach it to an envelope, you can bundle it up. Envelopes can also be easily carried by holding them overlapping each other.

Furthermore, since the base paper is made of synthetic paper using an oriented film (OPP) made from polypropylene resin using a biaxially oriented film forming method, it is strong and has an adhesive suitable for such synthetic paper. Since it is coated with a synthetic resin adhesive, it has strong adhesion to the main container.

In addition, the ends of the handrails were placed over the adhesive-applied surface of the base paper, and the ends were made to stand up almost parallel to each other, so the hanging load was equal to the length of the handrails. The information is transmitted to the base paper without any force in the direction, and there is no fear that the hand piece will separate from the base paper.

〔Example〕

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

First, the hand portion 11 used in the present invention will be explained.

FIG. 4 shows an example of this, in which a handpiece 12 is adhered to a base paper 14 coated with an adhesive 13, and the handpiece 12 is made of a synthetic resin low-foam tape made of polypropylene or polyester. , while the upper part is curled, the adhesive attachment portions at the ends are adhered to the base paper 14 in a state in which the left and right sides are substantially parallel.

In order to have more strength than ordinary paper, the base paper 14 is made of synthetic paper made of an oriented film (OPP) formed from polypropylene resin by a biaxially oriented film forming method.

In that case, the adhesive 13 applied to the adhesive side of the base paper 14 is vinyl acetate (EVA) adhesive, for example, ethylene-vinyl acetate (EVA).
Synthetic resin adhesives such as emulsions are preferred.

Then, a release paper 15 is pasted on this adhesive surface.

In this way, the hand piece 12 is attached to the adhesive 13.
It is adhered to the adhesive surface of the base paper 14 and interposed between the base paper 14 and the release paper 15.

Figure 1 shows the first sealing structure for packaging containers, etc. of the present invention.
This is a perspective view showing an embodiment, which is composed of a main container 1 made of expanded polystyrene and a lid 2 made of expanded polystyrene, as in FIG. 5 above.

After placing the product in the main container 1 and putting the lid 2 on,
The release paper 15 of the carrying portion 11 is peeled off, and the base paper 14 is pasted as a sealing paper on the joint between the main container 1 and the lid 2 so that the side of the base paper 14 to which the adhesive 13 is applied is in contact.
