Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a skin bank packaging method that is easy to open.

(Conventional technology) The recent development of packaging technology has been remarkable, and skin bank packaging is widely used for everything from medicines and foods to toys, office supplies, small household items, and even tools. .

(Problem to be solved by the invention) However, these openings are not always easy and smooth, and the two-layered part of the mount remains welded to the plastic film of the skin pack and peels off together with the packaged item. At present, the packaged item is removed by tearing off the peeled upper layer of the mount.

Alternatively, the space created between the plastic film and the packaged item is broken with another object and taken out.

In addition, in order to improve the above-mentioned points and make it easier to remove the packaged article from the plastic sheet covering the packaged article, an article packaging body in which a half cut is inserted in the backing paper was proposed in Utility Application No. 56-
57203 (Utility Model Application No. 57-169668), this method requires that a cup-shaped package be made in advance by thermoforming a transparent plastic sheet of almost the same shape as the packaged article. However, in order to adhere this to the mount, it is necessary to apply hot adhesive in advance to the position on the mount opposite the hem of the package, which is time-consuming. .

(Means for Solving the Problems) In view of these points, the present invention provides a method for packaging an object to be packaged and for unsealing and taking out the packaged object.
The work and handling are made simple and can be carried out reliably.

In other words, in the present invention, along the contour of the contact area of the packaged material, the packaging material is placed at a remote location outside of the contour, beyond the upper layer, to about the middle of the thickness of the packaging material. A notch, a so-called half-cut, is made, then the item to be packaged is placed inside the half-cut along this contour, and finally, this is wrapped with a heated plastic film, and
This is a skin pack packaging method in which the item to be packaged is wrapped and welded to a mount using a plastic film by degassing the air inside.

(Example) Hereinafter, a packaged product packaged by the method of the present invention will be explained with reference to the drawings, and the specific steps thereof will be explained.

Skin punk packaged products (A) packaged by the method of the present invention
) consists of a packaging mount (a), a packaged Th (b), and a packaging plastic film (C).

Next, the skin punk packaging method will be explained.

(6) Place a half-slice (2) on the packaging paper (a) along the contour of the contact area (1) of the packaged item (b) at a distance from this.

It depends on the thickness of this half cut (2Hj, mount (1)),
It is necessary to exceed at least the first layer (3) of the mount (a), and it may reach almost the middle of the thickness of the mount (a).

(2) Place the item to be packaged (b) in the half piece (2) along the outline of the mount (a).

■ Heated plastic film such as vinyl chloride (
When the packaging mount (a) and the object to be packaged (b) are wrapped in c) and the air inside the film (c) is degassed, the film (C) surrounds the object to be packaged (b). In this way, attach the mount (a
) to complete the skin pack packaged product (A).

A skin pack packaged product is completed through the above process, but in this case, if the packaged item is ball-shaped (not shown), the contact area with the mount is small, so the half-cut position is This is close to the projected position of the ball-shaped packaged object.

In any case, it is necessary to prevent the welded portion of the plastic film (c) to the mount (a) from entering the inside of the half-cut (2).

The one shown in Figure 1 is a typical one for explaining skin pack packaging, and the packaged object (b) is a rectangular parallelepiped, and the ones shown in Figures 3 and 4 are other examples. There it is,
The one shown in FIG. 3 is a columnar body (b) with flanges at both ends, and the one shown in FIG. 4 is a table clock (b).

In addition, on the mount (a), there is a 7.11 dissection part (4) in the corner part.
is provided.

To open such a skin pack packaged product (A),
When the plastic film (C) is peeled off by picking the peeling part (4) at the corner of the mount (a), the plastic film (C) is welded to the mount (a).
Peel off the Plus Deck film (C) from the mount (a).
This is done while the first layer part (3) is welded.

However, on the mount (a), there is a half-cut (
Since 2) is a container, when the 7-segment reaches this part, the peeling does not spread to the inside of the half-cut (2), but the surrounding plastic film (C) and the upper layer of the mount (a) ( 3
) The upper layer part (3) is peeled off from the mount (a) at the welded part.

At this time, the upper layer (3) of the packaged item (b) and the mount (a)
Therefore, depending on its shape, the packaged object (b) will either separate from the mount (a) along with the peeled side, or remain on the mount (a) side.

When separated from the mount (a) together with the release sides I and II, the mount (a) that has been peeled off together as in the conventional case is on the side of the packaged object (b) that has come into contact with the mount (a) Since the upper layer (3) is not attached, the packaged item (b) can be easily taken out.

(Effects of the Invention) The present invention includes a step of inserting a half-slice into the packaging board at a position away from the outside along the contour of the contact area of the packaged object, and a step of inserting the packaged object inside the half-slice. The process of placing the
Since the process consists of skin-backing the packaging mount and the packaged item with a heated plastic film, a plastic sheet package having almost the same shape as the packaged item proposed so far is pre-formed, and this package is Apply hot adhesive in advance to the position on the base plate facing the hem of the
This method does not require a lot of effort, unlike the method in which a half cut is placed along the inner edge of the application section, the object to be packaged placed in the half cut is covered, and the hem portion is heat-bonded to the backing paper.

According to the method of the present invention, skin-back packaging that is easy to open can not only be performed extremely easily, but also the packaged item does not move at all, and it can be quickly packaged regardless of the shape of the packaged item. can correspond to

In addition, when opening the package and taking out the packaged item, even if the plastic film is peeled off, the upper layer of the mount will peel off and stick to the side of the mount that comes into contact with the packaged item, as in the past. Since there are no holes, it is extremely easy to take out.

As described above, the present invention can easily and reliably perform skin-back packaging that is extremely easy to open, so it is suitable for use in skin-punk packaging, which has recently become extremely useful. It can be called an invention.
