[0001]

BACKGROUND OF THE INVENTION The present invention relates to a packaging bag for packaging foods such as sandwiches.

[0002]

2. Description of the Related Art Conventionally, as a bag for packaging foods such as sandwiches, there is, for example, the one disclosed in Japanese Utility Model Publication No. 2-32587.

That is, in this packaging bag, as shown in FIG. 15, of the two projecting pieces 6d and 7d formed at the ends, one projecting piece 6d is provided with two cut lines 21 and 21. And that score line
The bag body 1d is cleaved by gripping the gripping piece 22 between the cutting lines 21 and 21 from the points 21 and 21 and tearing the film 23 as shown in FIG.

[0004]

However, in the packaging bag as described above, the cutting lines 21 and 21 are formed only on one protruding piece 6d, and the two protruding pieces 6d and 7d are mutually connected. Since they are separate bodies that are separated from each other, it is not always easy to search for the cutting line 21, and therefore the tab 22 cannot be easily pinched when the bag body 1d is opened.

When the knob 22 is picked up and split,
The other protruding piece 7d, on which the tab 22 is not formed, is grasped, but in the packaging bag as described above, the two protruding pieces 6d, 7d made of a film are separated from each other. Therefore, the respective protruding pieces 6d and 7d themselves are not stiff, and therefore, when the protruding pieces 6d are cleaved, the other protruding piece 7d cannot be held in a stable state.

Therefore, due to the above-mentioned factors, there has been a problem that the operation of tearing the bag body 1d by the knob 22 cannot be easily performed.

The present invention was made in order to solve such a problem, and it is easy to search for a pick piece, the pick piece can be easily picked, and the protruding piece has a waist. It is an object of the present invention to easily perform the tearing operation of the bag body by the tabs as a whole.

[0008]

The present invention has been made in order to solve such a problem, and means for solving the problem is that both side edges of the front film 2 and the back film 3 are heated. The bag main body 1 is formed by welding and has a seal portion 5 on one end side of both films 2 and 3 and an opening 12 on the other end side, and from the seal portion 5 the both front and back films 2 and 3 are formed.
In a packaging bag for food such as sandwiches in which two projecting pieces 6 and 7 are formed by extending 3 respectively, both projecting pieces 6 and 7 are formed by sealing the one projecting piece and the other projecting piece. Are integrated to form the gripping header 20,
Moreover, a tongue-shaped gripping piece 11 serving as a starting point of cleavage of the bag body 1 can be separated from at least one of the protruding pieces 6 and 7 from the gripping header 20 through a separating means. It is to be formed in.

[0009]

That is, at least the upper end edge of one of the two projecting pieces 6, 7 is sealed to the other projecting piece side, and the projecting pieces 6, 7 are integrated so that the gripping header is formed.
Since the projecting pieces 20 and 20 are formed, the projecting pieces 6 and 7 are not separated from each other, and therefore, the gripping header 20 formed by the integration of the projecting pieces 6 and 7 is separated from the tongue piece through the separating means. The 20 is easily separated, and the tab 20 can be easily searched and grasped.

When the bag body 1 is torn by picking the knob 11 separated from the gripping header 20, the gripping header 20 is gripped. Since the projecting pieces 6 and 7 are integrally formed, the gripping header 20 is stiff, so that the gripping header 20 can be held in a stable state.

[0011]

Embodiments of the present invention will be described below. 1 to 3, reference numeral 1 denotes a substantially trapezoidal bag body, which is formed by welding a front film 2 made of a uniaxially stretched polypropylene film and a back film 3 made of the same material at both side edges 4 and 4. There is.

Reference numeral 5 denotes a seal portion formed in the lateral direction on the upper end side of the bag body 1, and by weakly heat-sealing the front film 2 and the back film 3 constituting the bag body 1, both films 2 and 3 are formed. The front film 2 and the back film 3 are extended to form substantially rectangular projecting pieces 6 and 7 on the upper portion of the seal portion 5 so that they can be brought into and out of contact with each other.

The upper edges 6a, 7a and the both side edges 6b, 6c, 7b, 7c of both the projecting pieces 6, 7 are heat-sealed to seal the upper edge and the both side edges with a seal portion 8 and a seal portion 9, respectively.
9 is formed, and the protruding headers 6 and 7 are integrated to form the gripping header 20.

Reference numeral 10 denotes an inverted U in the substantial center of the one protruding piece 6.
The cut line is formed in a letter shape, and the inside of the cut line 10 is formed as a tongue-shaped gripping piece 11 serving as a starting point of cleavage of the bag body 1.

Reference numeral 12 denotes an opening of the bag body 1, which is formed on the lower end side of the bag body 1.

A packaging bag having such a structure
As shown in FIG. 4, the sandwich 14 is used by accommodating the sandwich 14 in the bag body 1 and folding the surplus portion protruding from the sandwich 14 to wrap the sandwich 14 as shown in FIG.

Next, when opening the packaging bag 14 as described above, as shown in FIG. 7, the projecting pieces 6, 7 are sealed by the seal portions 8, 9, 9 at the upper edge and both side edges. When the gripping header 20 formed by the integration is gripped, the gripping piece 11 formed through the cut line 10 on one of the projecting pieces 6 is gripped and pulled, and thus the front film 2 forming the bag body 1
Is torn along the tearing direction of the film of the bag body 1 formed of the uniaxially stretched polypropylene film.

In this case, the two protruding pieces 6,
Since seal portions 8, 9, 9 are formed on the upper edge and both side edges of 7 and the projecting pieces 6, 7 are integrated to form a gripping header, the gripping header 20 is shown in FIG. As shown, only the tongue-shaped knob 11 is easily separated through the cut line 10, and the knob 11 can be easily searched and grasped.

When the bag body 1 is cleaved by picking the knob 11 separated from the gripping header 20, the gripping header 20 is gripped, and the gripping header 20 is Since the protruding pieces 6 and 7 are integrally formed as described above, the gripping header 20 is stiff, so that the gripping header 20 can be gripped in a stable state.

Further, a seal for integrally integrating the two separate protruding pieces 6 and 7 is formed on the upper edges 6a and 7a of the protruding pieces 6 and 7 in the direction intersecting the tearing direction of the knob 11. Therefore, when the bag body 1 is torn by the picking piece 11, the two protruding pieces 6 and 7 that are sealed are never separated from each other, so that the holding header 20 can be held in a stable state.

Furthermore, since the gripping piece 11 is formed apart from the upper edge of the sealed gripping header 20, when gripping the gripping header 20 and gripping the gripping piece 11 at the same time. It does not cause any trouble.

In the above embodiment, the seal portions 8, 9, 9 for integrating the two protruding pieces 6, 7 are provided with the both protruding pieces 6, 7.
Since it is formed on the upper edge and both side edges of the
Although the preferable effect that 7 is almost completely integrated was obtained, the seal portion does not necessarily have to be provided on the three peripheral edges of the upper edge and both side edges, and for example, as shown in FIG. May be formed.

Further, the sealing portion is not limited to the case where it is applied only to the peripheral edge as in the above embodiment, and as shown in, for example, FIGS. May be sealed. In this case, the area of the seal portion 15 is considerably larger than the area of the non-seal portion 16,
The integration of both projecting pieces 6 and 7 becomes more complete. However, the non-sealing part is
16 must include score line 10.

Further, the seal portion for integrating the both projecting pieces 6 and 7 is not limited to a linear shape, and may be, for example, an arc line shape.

In any case, the form of the seal does not matter, as long as both the protruding pieces 6 and 7 are integrated by the seal to form the gripping header 20.

Further, in the above embodiment, both projecting pieces 6, 7 are provided.
Although the upper edges 6a and 7a of the above are formed so as to be located on the same line, the upper edges 6a and 7a do not necessarily have to be located on the same line. For example, as shown in FIG.
The upper edge 6a of the one protruding piece 6 may be sealed to the other protruding piece 7 side so that the upper edge 7a of the one protruding piece 6 is located above the upper edge 6a of the one protruding piece 6, and in this case However, there is no problem in the ease of grasping the picking piece 11, and the protruding pieces 6 and 6
There is no hindrance to the integration of 7. However, the top edge
When 6a and 7a are located on the same line, both protruding pieces 6 and 7
This is convenient for bag making, since the film can be melted and sealed at the same time when forming.

Further, in the above embodiment, the score line 10 has a reverse U shape.
Although it was formed in a character shape, the shape of the cut line 10 is not limited to the embodiment, and may be formed in a substantially U shape as shown in FIG. 12 (a), for example. Same figure (b)
It may be formed in an inverted W shape as shown in FIG. In short,
It suffices that the projecting piece 6 is formed with a tongue-shaped gripping piece 11 which is separable via the cutoff line 10 and serves as a starting point of cleavage for cleaving the bag body 1 by its pulling force. It should be noted that the term "tongue-shaped" here means that the tab 11 is separated from the peripheral edges such as the upper edges of both projecting pieces 6 and 7 that require sealing, and the tab 11 can be pinched. The shape of the "tongue piece" does not matter.

As shown in FIG. 14 (a), it is possible to store the tissue paper 18 in the gap 17 between the projecting pieces 6 and 7. In this case, the tissue paper 18 is picked via the cut line 10. After the piece 11 is picked up and the bag body 1 is cleaved, the tissue paper 18 can be picked out from the opening 19 formed by removing the picked piece 11 as shown in FIG. The gap 18 between the protruding pieces 6 and 7 functions as a tissue box, and the tissue paper is used when the sandwich 14 stored in the bag body 1 is eaten.
There is an advantage that 18 can be used as a towel.

Furthermore, it is also possible to attach a hand towel (not shown) which is wet with water and stored in a bag to the upper surface of the knob 11, and in this case, the hand towel is stored. By gripping and pulling the bag, the tab 11 can be pulled at the same time and the bag body 1 can be cleaved. In this case, there is an advantage that the bag-like hand towel can be detached from the packaging bag 13 at the same time as the bag body 1 is opened, and the hand towel can be used at the same time when the sandwich 14 is eaten.

Further, in the above embodiment, the separating means for separating the picking piece 11 was formed by the score line 10.
As the separating means, other than the score line 10 of the embodiment, for example, a perforation line or the like may be used, and further, a half cut, that is, a tear line weakened by heat may be used. Well, the separating means does not matter. For example, as shown in FIG. 13, it may be constituted by both the score line 10 and the perforations 10a. Further, in this embodiment, the separating means such as the cut line 10 is formed apart from the seal portion 5, but the separating means may be formed so as to contact the seal portion 5.

The point is that any means can be used as long as it can separate the picking piece 11 from both the protruding pieces 6 and 7 integrated by the seal.

Further, in the above-mentioned embodiment, the bag body 1 is composed of a uniaxially stretched polypropylene film, but the material of the bag body 1 is not limited to this, and it is a biaxially stretched or non-stretched polypropylene film. It may be present, or may be a film made of other synthetic resin such as polyethylene, and the material thereof does not matter.

However, when the film has a tearing direction like a uniaxially stretched polypropylene film,
The bag body 1 can be easily torn by the pulling force of the tab 11 formed by being surrounded by the score line 10. However, even if the film is a versatile film having no orientation, the tab
When 11 is formed in a horseshoe shape, there is an effect that the film can be torn linearly in the tearing direction by tensile stress. However, when the film does not have a tearing direction, it is preferable that the bag main body 1 be provided with a guide tear line such as a perforation or a half cut induced by the pulling force of the knob 11.

Further, in the above embodiment, the seal portion 5 at the boundary between the bag body 1 and the projecting pieces 6 and 7 is formed by weak heat sealing. Etc., and the means for sealing the same does not matter.

Further, in the above embodiment, the case where the sandwich is used as the object to be packaged has been described, but the kind of the object to be packaged is not limited to this, and may be rice balls or the like. Well, the kind does not matter. The point is that food only has to be used as an article to be packaged.

Further, in the above embodiment, the bag body 1 is formed in a substantially trapezoidal shape for suitable packaging in accordance with the sandwich form, but the shape of the bag body 1 is not limited to this. , It can be arbitrarily changed according to the type of food to be packaged.

Further, in the above embodiment, the knob piece 11 is formed only on one of the protruding pieces, but the knob piece 11 may be formed on both of the protruding pieces 6 and 7.

Further, in the above-described embodiment, the cut line 10 forming the knob 11 is formed separately from the seal portion 5, but the end of the cut line 10 is continuous with the seal portion 5. It may be formed by.

[0039]

As described above, according to the present invention, at least the upper edge of one of the two projecting pieces is sealed to the side of the other projecting piece to integrate the two projecting pieces. A gripping header is formed, and at least one of the projecting pieces has a tongue-shaped gripping piece serving as a starting point of cleavage of the bag body, which can be separated from the gripping header through a separating means. Since it is formed, the tongue-shaped gripping piece is easily separated from the gripping header through the separating means, and the gripping piece can be easily searched and gripped.

Then, when the bag body is cleaved by picking the gripping piece separated from the gripping header, the gripping header is gripped, and the gripping header seals the both protruding pieces. Since it is formed integrally, the gripping header is stiff, and thus the gripping header can be held in a stable state.

Therefore, due to such factors, in the present invention, as compared with the above-mentioned conventional packaging bag, the remarkable effect that the work of tearing the bag body by the gripping piece can be performed remarkably easily and reliably. Came to have.
