DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a hermetically sealed package of tissue paper or confectionery, and in particular, a tissue paper polymerized by moistening a cleaning liquid or a face wash, or a damp paper. The present invention relates to a package which can hold an article, such as confectionery, which is disliked by taking out one by one, in a sealed state except when the article is taken out.

[Conventional technology]

A conventional sealed package of this type is, for example, the one disclosed in Japanese Utility Model Publication No. 58-31823 in the name of the present applicant.

As shown in FIG. 5 and FIG. 6, this hermetically sealed package has a non-breathable sheet-like wrapping material (12) tightly wrapping an object to be packaged, and the wrapping material (12) is placed on the wrapping material (12). A long U-shaped cut line (15) is attached to the piece (12a), and an inner region (14) which is an internal region of this cut line (15) has a sheet-like outer cover larger than that. (16) is polymerized and the outer lid (16) is adhered to the upper piece (12a) with a re-adhesive adhesive (17).

According to this, as shown in FIG. 6, when the outer lid (16) is peeled upward by the semi-circular side of the cut line (15),
The inner lid (14) remains attached to the lower surface of the outer lid (16) and is notched.
A part of the article to be packaged (11) can be taken out through the opening (13) which is separated from the packaging material (12) along the (15) and is formed thereafter.

Then, when the outer lid (16) is closed again, the inner lid (14) is opened (13).
To close the opening (13) and the outer lid (16)
The adhesive (17) again adheres to the upper piece (12a) of the packaging material (12) to completely seal the article to be packaged (11).

[Problems to be solved by the device]

According to the conventional sealed package as described above, unless the outer lid (16) peeled upward is properly stopped at the end of the score line (15), both ends of the score line (15) are covered with the outer cover (16). 16), and the cut portion impairs the hermeticity of the packaged object (11) after re-adhesion of the outer lid (16), or the inner lid (14) together with the outer lid (16). ) May be completely torn from the packaging material (12).

In order to prevent such cutting progress and tearing of the inner lid (14), for example, as shown in FIG. 7, both end portions (15a) of the cut line (15) are arcuate toward each other inward. Bend or, as shown in FIG. 8, at both ends of the score line (15),
It has been proposed to form a circular or substantially circular hole (18) (see, for example, Japanese Utility Model Laid-Open No. Sho 58-19966). However, in this case, the inner lid (14) and the packaging material (12) are formed. Since the connecting part with and becomes shorter, the strength of this part may be reduced and the inner lid (14) may be easily torn off.In any of these cases, the outer lid (16) and the packaging material (1
The boundary line (L) of the bonded portion with 2) is always linear as shown by the alternate long and short dash line in FIGS. 6 and 8,
There is a problem in that it is difficult to obtain the tearing-off prevention force of the inner lid (14) that is too large.

An object of the present invention is to provide a hermetically sealed package that solves these problems.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, the present invention close-packs an article to be packaged with a non-breathable sheet-like packaging material, and attaches a substantially U-shaped cut line to the upper piece of the packaging material, and Above that, a large sheet-shaped outer cover that covers the cut line,
With an adhesive, by adhering to the extent that it is peelable and re-adhesive, the inner lid, which is the inner region of the cut line, leaves a continuous portion with the packaging material when the outer lid is peeled off.
In a hermetically sealed package which is peeled off from a packaging material together with an outer lid, and thereafter an opening for taking out an article to be packaged is formed, a terminal portion of the cut line is branched into two, and one of the branched portions is It is characterized in that it is curved in an arc shape toward the outside and the other branch portion toward the inside.

[Action]

According to the hermetically sealed package of the present invention, when the inner lid is separated along with the outer lid along the cut line to the continuous portion with the packaging material, the cut line is bifurcated at the end portion. The force is divided into two by, and it becomes difficult for the inner lid to be cut off from the end of the score line in the peeling direction, and the possibility of tearing the inner lid is reduced.

In particular, when the outer lid is opened to some extent and then pulled further in the direction to open it with a strong force, a trapezoidal space is formed at the end of the opening, and the adhesive portion between the outer lid and the packaging material is formed. The center part of the boundary line is deformed so as to be recessed into a trapezoidal shape, and accordingly, the part near the boundary line of the outer lid is deformed to form a three-dimensional rib structure, and the outer lid is further pulled. Peeling can be strongly prevented.

〔Example〕

Next, one embodiment of the present invention in the case where the object to be packaged is a moistened wiping paper will be described with reference to FIGS. 1 to 4.

In (1), a large number of wiping papers, cottons for wiping, non-woven fabrics, etc. (hereinafter collectively referred to as wiping papers (1a)) are folded in a Z shape so that they can be taken out one by one from above. A cleaning liquid is impregnated into each wipe paper (1a) which is a rectangular object to be packaged.

(2) is a sheet-like packaging material made of polyethylene, for example, and this packaging material (2) is wrapped around the object to be packaged (1) to form a packaging material (2).
The lower surface overlapped part is heat-fused with the fusion line (2a) in the vertical direction (longitudinal direction), and both sides of the packaging material (2) are heat-fused with the fusion lines (2b) and (2b) in the horizontal direction. Items to be packaged by wearing (1)
Is sealed.

A substantially U-shaped longitudinal cut line (5) is cut approximately in the center of the upper piece (2c) of the packaging material (2), and the inner area is an inner lid.
It is (4).

The score line (5) can be a completely cut continuous cut line or a fragile line such as a perforation or a V groove.

Both ends (5a) of the score line (5) are bifurcated into an arcuate branch (5b) directed outward and an arcuate branch (5c) directed inward.

(6) is made of the same material as the packaging material (2) and has an inner lid
(4) A sheet-like outer lid having a larger rectangular shape, and a non-curable adhesive adhesive (7) attached to the lower surface thereof.

The outer lid (6) is the upper piece (2c) of the packaging material (2) centering on the inner lid (4).
It is adhered to the upper surface of the with a re-adhesive adhesive (7).

In addition, (6a) is an inner lid (4) for convenient peeling of the outer lid (6).
It is preferable that the ear piece is provided at the center of the free end side (the left end in FIG. 1) of the above, and the adhesive agent (7) is not attached to the lower surface thereof.

In the hermetically sealed package of this example, the packaging material (2) is a fusion line (2a) (2
b), and the opening (3) formed after cutting the score line (5) is closed by the inner lid (4),
The outer edge of the outer lid (6) is the upper piece (2) of the packaging material (2) around the opening (3).
By being adhered to c), the bundle of wiping paper (1a) (1)
Is completely sealed. Therefore, the cleaning liquid impregnated in the wiping paper (1a) will not leak or evaporate (see FIGS. 1 and 2).

If you want to remove the wiping paper (1a) and use it, use the earpiece (6a).
Pinch and peel off the outer lid (6) from the left end of Fig. 1 toward the right. Then, the inner lid (4) is separated from the packaging material (2) together with the outer lid (6) while being adhered to the inner surface of the outer lid (6).

As shown in FIG. 3, the inner lid (4) is connected to the wrapping material (2) at the connecting portion (4
After being opened to b), it is difficult to separate the inner lid (4) and the outer lid (6) any further.

However, if the outer lid (6) is peeled off too strongly against the adhesive force of the adhesive (7), the end of the outer lid (6) is separated from the packaging material (2) and the inner lid (4) is torn off. May be

In this embodiment, the terminal portion (5a) of the score line (5),
Since it is branched into two branch parts (5b) (5c) directed to the outer side and the inner side, the force is divided here, and the inner lid (4) is separated from each end of the score line (5). There is less risk that the inner cover (4) will be torn off and the inner lid (4) will be torn off.

In particular, if the outer lid (6) is pulled further in the direction to open it from the state shown in FIG. 3 with a strong force, as shown in FIG. 4, a trapezoidal shape indicated by a chain double-dashed line at the end of the opening (3). The space (8) is formed and the boundary line between the outer lid (6) and the packaging material (2)
As shown by the alternate long and short dash line in FIG. 4, (L) is deformed so that the central portion is recessed into a trapezoidal shape, and accordingly, the vicinity of the boundary line (L) of the outer lid (6) is three-dimensional. The outer lid (6) can be strongly prevented from being peeled off further by deforming so as to form a general rib structure.

After that, the opening (3) formed by separating the inner lid (4)
Thus, the wiping paper (1a) can be taken out one by one (see FIG. 3).

At this time, the base end (4b) side of the inner lid (4) in the opening (3) is
By opening both branch parts (5b), (5c) of the score line (5), the cutting line (5) is greatly expanded, and the wiping paper (1a) can be taken out more easily than in the conventional case.

After removing the wiping paper (1a), when the outer lid (6) is closed again, the inner lid (4) fits into the opening (3) to close the opening (3), and the adhesive (7) The outer lid (6) is the upper piece (2c) of the packaging material (2)
Then, the article to be packaged (1) is completely sealed.

Therefore, according to this wiping paper package, the outer lid (6) can be opened and closed many times until the wiping paper (1a) is used up.

In addition, in order to manufacture the hermetically sealed package of this example, after the cut line (5) was attached to the packaging material (2) by a pressing device or the like, the outer lid (6) was attached to the upper surface thereof, and then, The article to be packaged (1) may be wrapped and fused by the packaging material (2) in the same manner as a conventional method of packaging tissue paper or the like.

Therefore, it is possible to easily manufacture and it is also easy to automate the manufacturing operation.

As disclosed in the above-mentioned Japanese Utility Model Publication No. 58-31823 as an embodiment shown in FIG. 2 (FIGS. 4 to 6 of the publication), the present invention is designed so that both end portions of the packaging material are covered with each other. Of course, the present invention can also be applied to a type in which upper and lower parts of a package are superposed on each other so as to be bonded to each other.

[Effect of device]

As is clear from the above, according to the hermetically sealed package of the present invention, when the outer lid and the inner lid adhered to the outer lid are opened, there is a risk that the packaging material may be cut and the inner lid may be torn from the packaging material. It is small and its durability can be greatly improved compared to the conventional one, and both branches of the score line are opened at the time of opening the lid, which greatly expands the opening on the base end side of the inner lid, There are advantages such as easy removal of the package.

In particular, when the outer lid is opened to some extent and then pulled further in the direction to open it with a strong force, a trapezoidal space is formed at the end of the opening, and the adhesive portion between the outer lid and the packaging material is formed. The center part of the boundary line is deformed so as to be recessed into a trapezoidal shape, and accordingly, the part near the boundary line of the outer lid is deformed to form a three-dimensional rib structure, and the outer lid is further pulled. Peeling can be strongly prevented.
