Abstract

PURPOSE: To obtain a packaged body in shrink packaging for which only the top can be opened entirely on unsealing by a simple operation. CONSTITUTION: In a pillar-type package made by heat shrinkage (so-called shrink packaging) wherein a heat-shrinked bag body is sealed with an end seal 4 provided perpendicularly against a cut tape 2 provided horizontally at the inside on both sides of the end seal 4, a starting point for unsealing is provided at the outside on U-shaped cuts 8 provided at the right and the left of the end seal with film-like adhesive pieces 9 put for separably covering both of the U-shaped cuts. Thereby, the package can be unsealed easily in a manner of taking-out a lid by virtue of the direction wherein the end seal is provided and the structure wherein starting point for unsealing is provided. The package in the structure as mentioned above is available not only for easy unsealing in the manner of taking-out the lid, but also for taking out neatly only the upper part of the package. Therefore, the package with its lower part left unsealed can be used promptly as a tray for display.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat-shrink type (hereinafter referred to as shrink type) film packaging opening mechanism for foods, medicines, cosmetics and other products such as prismatic, columnar, disk-shaped, bottle-shaped and the like, or product storage containers. It is about improvement.

[0002]

2. Description of the Related Art A shrink-type film package is not only capable of full-scale packaging of a conventional paper box or the like, but also transparent so that the contents can be recognized from the outside, which is also useful for cost reduction. Further, since it has a shrink form, it has an advantage that it can be applied to any product shape.

However, this type of conventional shrink wrapping has a pouch-type wrapping, in which the end seal of the bag is provided horizontally and only one cut tape is attached to the inner surface on one side, as is the case with the pillow type wrapping. There is. Therefore, when opening the package, only one side is linearly opened in one direction and one side is opened, and further processing such as cutting and tearing is required to take out the contents, and the torn line is irregular. There were some drawbacks such as lack of aesthetics.

[0004]

In view of the above-mentioned drawbacks when the conventional shrink wrapping body is opened, not only the shrink wrapping with a tape is possible regardless of the shape of the contents, but at the same time, The invention of a shrink wrapping body having a novel structure is provided for the purpose of performing shrink wrapping that opens and closes the entire surface and allows the display and removal of products with the upper part completely and exposed. I made an earlier application. (Japanese Patent Application No. 5-338842). The present application relates to an improvement of the opening mechanism of the package according to this earlier application. .

[0005]

[Means for Solving the Problem and Its Action] In both the previous application and the present application, the sheet 5 is wrapped in a sheet-shaped plastic film 1 shown in FIG. Both edges A and B are joined together to form a cylindrical seal 3 (Fig. 8b), and the front and rear of the packaged object are sealed with an end seal 4
(Fig. 8c), and then shrink film 1 is shrunk film (Fig. 8d)
The present invention relates to so-called shrink packaging using vinyl chloride, polypropylene, polystyrene, vinylidene chloride copolymer and the like.

[0006] Further, when laying on the package object of the present application, as shown in FIG. 8, one cut tape (the tear tape) is formed on each line corresponding to both inner side surfaces of the opening portion of the heat-shrinkable plastic film 1. -P) 2 is affixed in advance, and FIG.
When the pillow packaging is performed according to the steps (a) to (d), the end seal 4 is set in the vertical direction, that is, the direction (Z) orthogonal to the direction (X) of the cut tape, and then heat shrinking is performed. A heat-shrinkable package having a novel form, which is characterized by the above, can be obtained, and the previous application was filed. As will be described later, this package is a new type of package that can be opened from the opening section 41 to the left and right, and the upper part can be completely removed like a lid. Therefore, it is extremely easy to take out from the packaging of toys, canned goods, irregularly-sized bottles, fruits and vegetables,
It is possible to provide a new packaging form which has a number of advantages such as simplification and the ability to completely remove only the upper packaging and display the contents while keeping the packaging in the lower packaging.

Prior to the previous application, one cut tape was attached to only one side as an ordinary pillow package. Therefore, when the package is opened, the one side to which the one-sided cut tape is attached only linearly opens in one direction on one side, and the extraction and replacement of the contents were extremely complicated.

At this time, even if one cut tape is attached to each of the right and left sides, the end seal 4 as in the present invention is used.
Is not (Z) structure orthogonal to the direction (X) of the cut tape, the package cannot be manufactured with the double-sided cut tape joined due to the manufacturing technology of the package. It was impossible to form a completely open lid over the entire circumference as in the present invention only by forming linear openings on both side surfaces.

On the other hand, in the present invention, FIG.
(A) Or, as shown in FIGS. 2 to 7 and 8, the end seals 4 are orthogonal to the cut tapes 21 and 22 attached to both side surfaces, and the ends of the cut tapes 21 and 22 come into contact with each other at the intersection 41. Since it is in a state, by pulling the ends of both sides to the left and right, the package can be completely separated vertically, and the upper part of the shrink package can be opened like an open lid.

In summary, in the conventional heat shrink packaging construction, there has never been a seal type in which the end seal 4 is perpendicular to the cut tape 2. Therefore, it is not possible with the conventional type to butt the ends of the cut tape against both inner side surfaces of the end seal part and open the entire surface openly. That is what I got.

The present application relates to improvement of the opening mechanism of the shrink wrapping body having the above-mentioned configuration according to the prior application. 1. FIG. 1 shows an example of a concrete implementation of the present invention. FIG.
(A) is attached to the end seal part 4 of the package and both inner side surfaces of the package, and the left and right end edges 21, 21 of the cut tape contained therein,
22 Make a U-shaped cut 8 on the left side of the outer bag (a).
It is provided on the right (b).

With this configuration, when the tongue-shaped U-shaped cut 8 (a) is pulled when opening,
With this as a starting point, the action of the cut tape existing on the inner surface thereof causes the package body to be opened (counterclockwise in the figure) along it. Similarly, it can be opened on the opposite side (clockwise) starting from 8 (b), and as a result, the entire surface can be opened like a lid (Fig. 1B). Such unsealing is performed by shrinking the end seal portion 4 invented by the present invention or the like from the left and right with a shrink tape, and a U-shaped cut on the left and right sides. This is a new effect that can be achieved only when the combination is performed.

2. Further, U-shaped cuts provided on the left and right sides of the end seal portion, which are the opening starting points 41 of the package having such a structure, are separately provided on the left and right sides or commonly on the left and right sides.
It is covered with an adhesive piece 9 coated with an adhesive from above (Fig.
First, the package can be kept airtight. At the same time, when opening, the non-adhesive portion (10a, 10b) provided on the edge of the adhesive piece can be grasped and pulled to make the opening easier.

That is, FIG. 2 (e) shows an adhesive piece 9 applied to the back surface of the adhesive, and both ends are provided with a portion 10 which does not apply the adhesive and serves as a grip portion when the bag is opened. FIG. 2F shows a state in which the U-shaped cut 8 is attached to the bag body from the outside so as to cover the entire surface (top view). Similarly, FIG. 2 (g) shows a side sectional view of this portion.

As is clear from FIG. 2 (f, g), at the opening starting point 41, strip-shaped cut tapes are attached to the left and right 21, 22 on the inner surface of the package (shrinking film) 1.
An adhesive piece 9 is attached to the outer surface of the package so as to cover the U-shaped cuts 8 provided on the left and right sides near the end seal portion of the package.

When the unsealing starting point has such a structure, at the time of unsealing, first, the non-adhesive portion 10 provided at the end of the adhesive piece 9 is opened.
When (a) is grasped and pulled, since the adhesive piece is detachably attached by the adhesive layer 23, it can be easily peeled off and the U-shaped cut 8 (b) on the side opposite to the non-adhesive portion 10 (a) Starting from, the tear opening of the bag body 1 proceeds with the cut tape 22 below it.

Next, when the U-shaped cut 8 (a) on the opposite side of the opening start point in the opened state is pulled, the tear opening is advanced on the left side together with the lower cut tape 21. Thus, it is possible to perform tearing and unsealing of the entire circumference like a lid by performing unsealing with the right side and then the left side around the opening starting point.

When the opening starting point has such a structure, the perforated part formed by the U-shaped cut is kept airtight by the adhesive piece, and the alteration of the contents can be prevented in advance, and the end of the adhesive piece is opened at the time of opening. You can open the entire surface just by pulling.

The cut pattern to be provided as the starting point of opening on the package is not limited to the U-shape illustrated in FIGS. 1 and 2, but may be square (FIG. 3L) or mountain-shaped. (E), etc. can be arbitrarily selected. In the present application, these are generically described as U-shaped cuts. Further, the adhesive piece 9 may extend over the end seal 4 and be covered with a single adhesive piece in common with the left and right cut patterns (Fig. 2, f, g), or left,
You may cover the cut patterns separately on the right (Fig. 3, Nu, Le).

When the handle portions 10 provided on the adhesive piece 9 and not coated with the adhesive agent are provided at both left and right ends (see FIG.
F, G; Fig. 3 ・ E), when installed in the center (Fig. 3 ・
In both cases, the cut pattern on the left and right sides of the end seal part of the bag body is covered airtightly and the pulling force is applied to the bag body. Any shape can be adopted as long as it is in the direction of tearing.

3. As an advantageous application mode of the unsealing mechanism of 1 and 2 according to the invention of the present application, a case where such unsealing mechanism is provided on both the front and the back of the package can be mentioned.

For example, as shown in FIG. 4 (T), the opening starting point of [a structure in which the U (corner or mountain) -shaped cuts on the left and right are covered with one adhesive piece 9] 9F) and the back (9
If it is provided on both the R side and both sides, if one end 10 (a) (left side) of the adhesive piece on the front side (9F) is pulled, the adhesive piece 9 (F) will peel off and the U-shaped cut on the right side will be torn, While pulling the cut tape in order, the package is opened along with it. When this reaches the opening starting point 9 (R) on the back side, the opening operation similar to that on the front side 9 (F) works continuously, and due to the connecting effect of the cut tape and the adhesive piece, as shown in Fig. It is possible to continuously perform the tearing operation even at the opening starting point of, and the surprising effect that the tearing of the entire circumference of the package can be advanced at once with one operation is obtained.

In other words, when the opening starting points of the above construction are provided on the front and back sides of the package, if opening is started rightward (or leftward) at one location, the opening is continued all around in one operation. As a result, the practically important effect, which will be described later, can be obtained by opening the lid completely.

[0024]

EFFECT OF THE INVENTION The present invention is a shrink wrap according to the invention previously filed by the inventor in which the cut tape is in the horizontal direction (X) and the cut seal is in the vertical direction (Z). This can be done for the first time in a packaging body having a new configuration in which cut tapes are arranged on both inner side surfaces of the rule 4, and the present application relates to the configuration of the opening starting point of such a packaging body. Have an effect.

(1) In other words, the cut tape is in a state of being horizontally butted against the end seal direction (vertical).
By providing a U-shaped (mountain, square) -shaped cut on the outer bag body of the container, the entire body can be opened like a lid by pulling the U-shaped (mountain or square) cut at the same time.

(2) Further, when the left and right U-shaped cut portions are separately or commonly covered by the adhesive pieces so as to be peelable, the airtightness impaired by the U-shaped cut is provided. When restoring the handle and pulling the handle (non-adhesive portion) provided on the edge of the handle, it becomes possible to easily and easily open the entire surface like a lid.

(3) As one aspect of the present invention, in the case where two opening U-shaped cuts are covered with one adhesive piece and two such opening start points are provided on the front and back sides of the package, The unsealing operation caused at the unsealing start point on the front side can be advanced all at once over the entire circumference, and a package excellent in operability can be obtained.

In the package having such a structure, the horizontal direction (X) of the cut tape is made vertical with respect to the direction (Z) of the end seal, which is limited in the present application, and both ends of the end seal portion are arranged. This is the first effect that can be achieved in the shrink package according to the combination of the structure in which the cut tape is attached to the side surface and the opening start point according to the present application.

(4) The invention of the present application is, for example, a cylindrical shape as shown in FIG. 5A (for example, a tea canister, etc.), a disk shape as for (LA) (for example, a cheese container, etc.), or a box as shown in FIG. The present invention can be arbitrarily applied to various modes and uses, such as a body provided with opening points at the corners of the body, a body having a large number of bottles as shown in FIG. 7, and the like. (5) In the case of such a package, the upper part (M) can be easily removed so that the lid can be removed in one operation, and it is used for packaging precision parts. By removing N), it is possible to prevent the attached article from being contaminated by the skin oil of the hand. (6) Especially in the case of Fig. 7, when exhibiting at a store,
Remove only the upper part (M) of the transport package by opening the lid,
The lower part (N) is displayed as it is, instead of a tray (bowl-shaped container), containing the contents, and it offers a new packaging usage form, which has the advantages that it can be used for picking up one piece (piece), displaying, and selling. There are also possible effects.
