BACKGROUND OF THE INVENTION
The present invention relates to a packaging bag for foods for packaging foods such as sandwiches and castellas (hereinafter referred to as “sandwiches”), and more specifically, the sandwiches that have been properly opened and packaged can be taken out properly. The present invention relates to a packaging bag for foods, in which the sandwich sandwich is not easily deformed even when an external force is applied to the side surface of the packaging bag (the result of packing the sandwich with the packaging bag).
[0002]
[Prior art]
Right-angled triangular sandwiches are sold in the form of food packaging bags as shown in FIGS. In this food packaging bag, both side edges 111 and 121 of the trapezoidal front film 110 and the back film 120 that are overlapped as shown in FIG. The “upper” side is sealed by a strip-shaped seal portion 101, and the wide other end (hereinafter referred to as “lower”) side can be opened by the opening 102. In order to make the opening 102 easy to expand, the front film 110 is formed slightly shorter than the back film 120 as shown by the dotted line in FIG. 6, or the back film 120 is formed slightly shorter than the front film 110. Has been.
[0003]
Further, the upper side from the seal portion 101 is the protruding pieces 112 and 122 in which the front film 110 and the back film 120 are overlapped, and the periphery of the protruding pieces 112 and 122 is extremely finely sealed by heat. In some cases, the upper edges of the protruding pieces 112 and 122 have a design-rich shape such as an arc shape or a wave shape.
[0004]
Further, the protruding piece 122 of the back film 120 is provided with an inverted U-shaped cut line 123, and the inside of the cut line 123 is a tongue-shaped knob piece 124. Since the front film 110 and the back film 120 are merely superimposed, the knob 124 can be picked up. On the inner surface of the back film 120, a thin strip-shaped cutting means (hereinafter referred to as “cut tape”) for tearing the back film 120 from the knob 124 to the vicinity of the opening 102 across the seal portion 101. 103 is pasted.
[0005]
In such a food packaging bag, the front film 110 and the back film 120 are overlapped with each other, and the front film 110 and the back film 120 are bent at a right angle as shown in FIG. And the opening 102 is opened in a rectangular shape, thereby forming a bag-shaped space 104 having substantially triangular side surfaces. The sandwich S is accommodated in the space 104, and the front film 110 and the back film 120 on the opening 102 side are folded into a bottom 105 as shown in FIG. 8, and the bottom 105 is an adhesive tape (not shown). And the sandwich S is packaged.
[0006]
And in order to eat the sandwich S packaged, the cut tape 103 provided on the protruding piece 122 of the back film 120 is picked and pulled straight downward so that the cut tape 103 is sealed as shown in FIG. The back film 120 of 101 is cut and then pulled straight downward to tear the back film 120 downward. When the back film 120 is torn toward the bottom 105, the food packaging bag is opened, and the sandwich S can be taken out from the torn back film 120 side.
[0007]
In such a food packaging bag, the narrower one of the cut tape 103 is easier to tear the back film 120, so that a thin one is generally attached to the back film 120. However, since the sandwich S is wide, it is difficult to take out the sandwich S only by tearing the back film 120 thin, and in order to take out the sandwich S, the interval between the back torn films 120 must be widened. Is troublesome.
[0008]
Therefore, an opening film piece for tearing the back film with a wide width and a pair of belt-like protective tapes arranged on both sides of the opening film piece are each attached to the back film. A food packaging bag is disclosed in Japanese Utility Model Registration No. 3084968.

The food packaging bag disclosed in Utility Model Registration No. 3084968 is provided with an opening shooting piece on the upper end of a wide opening film piece attached to a back film. By pulling the opening image piece downward, the back film is torn by the width of the opening film piece. And a pair of band-shaped protective tapes affixed to the back film on both sides of the opening film piece prevents the back film from being torn unnecessarily wider than the width of the protective tape, and the sandwich is spilled inadvertently. Not to be.
[0011]
By the way, any conventional food packaging bags, including the food packaging bags disclosed in the utility model registration No. 3084968, were packaged with unnecessarily external force applied to the side surfaces of the packaging bags when opened. The sandwich may be deformed as if it was crushed. This is because it is not considered that any conventional food packaging bag is reinforced to maintain the regularity of the packaging bag.
[0012]
Therefore, the present invention provides a food product in which the packaged sandwich is not easily deformed even if an external force is applied to the side surface after the sandwich that has been opened and packaged properly can be taken out properly. It is an object to provide a packaging bag.
[0013]
[Means for Solving the Problems]
The packaging bag for food according to the present invention is such that both side edges of the superposed front film and back film are sealed, one end side is sealed by a seal part, and the other end side can be opened by an opening part. Or, in a food packaging bag in which the portion of the back film that is torn from the seal portion side to the opening portion side is a tear portion, it is attached to both sides of the film provided with the tear portion to regulate the width of the tear portion Each of the paired guide sheets is formed so as to straddle the folding line on the side edge side of the film.
[0014]

Furthermore, the upper side from the seal portion 1 is the protruding pieces 12 and 22 in which the front film 10 and the back film 20 are overlapped, and the periphery of the protruding pieces 12 and 22 is extremely finely sealed by heat. A trademark or the like is printed on the protruding pieces 12 and 22, and the protruding pieces 12 and 22 are picked so that the packaging bag can be taken out from the display shelf. Furthermore, the upper edges of the protruding pieces 12 and 22 may have a shape with a good design such as an arc shape or a wave shape.
[0021]
Then, an inverted U-shaped cut line 23 is put in the protruding piece 22 of the back film 20, and the inside of the cut line 23 is a tongue-shaped knob piece 24. Since the front film 10 and the back film 20 are merely superimposed, the knob 24 can be picked up.
[0022]
A strip-shaped cutting means (hereinafter referred to as “cut tape”) 3 for tearing the back film 20 is attached to the inner surface of the back film 20. The cut tape 3 is pasted from the knob 24 to the vicinity of the opening 2 so as to intersect the seal 1 so as to be orthogonal to the center of the seal 1.
[0023]
A portion that is wider than the cut tape 3 and is torn to the opening 2 side from the seal portion 1 of the back film 20 is defined as a cleavage portion 25. The cleavage portion 25 has a width that facilitates removal of the sandwich S to be packaged (see FIG. 7), for example, a wide width of at least 20% or more, preferably 50% or more of the length of the seal portion 1. Note that the cut tape 3 from the seal portion 1 to the vicinity of the opening 2 may have the same wide width as the cleavage portion 25.
[0024]
In the food packaging bag according to the present embodiment, the pair of guide sheets 4 for regulating the width of the tearing portion 25 are on both sides of the tearing portion 25 of the back film 20, respectively. It is characterized by being provided so as to straddle the folding line 26 on the edge 21 side. The guide sheet 4 is provided so as to straddle the folding line 26 on the side edge side, so that the packaging bag for food is superimposed on the corner portion 27 (see FIG. 5) of the back film 20 in the state where the sandwich S is packaged. In addition to reinforcing the corner portion 27, the guide sheet 4 is formed between the pair of side edges 21, 21 on the side of the fold lines 26, 26, and between the one fold line 26 and the side edges 21. The back film 20 is reinforced in a state of being superimposed on the side surface 20b, and the packaged sandwich S is not easily deformed even when an external force is applied to the take-out surface 20a or the side surface 20b.
[0025]
Further, the guide sheet 4 is formed to a length from the seal portion 1 to the planned folding line 28 on the other end side of the back film 20. Since the back film 20 is folded at the planned folding line 28 to wrap the sandwich S, the guide sheet 4 matches the height of the packaged sandwich S and is overlapped with the back film 20 so that the external force in the vertical direction is increased. Even when added to the packaged sandwich S, the sandwich S is not easily deformed.
[0026]
As such a guide sheet 4, the inner side edge 4a coincides with the lines on both sides of the cleavage portion 25, and the outer side edge 4b is finely sealed, and the side edges 11, 21 is formed in a trapezoidal shape such that the upper edge 4 c coincides with the seal portion 1, and the lower edge 4 d coincides with the expected folding line 28 of the back film 20. The trapezoidal guide sheets 4 and 4 are adhered to the back film 20 over the entire circumference or the entire surface by heat, adhesive, or the like.
[0027]
Such a guide sheet 4 is adhered to the inner surface of the back film 20 as shown in FIG. 3 or the outer surface of the back film 20 as shown in FIG. When the guide sheet 4 is attached to the inner surface of the back film 20 as shown in FIG. 3, the outer edge 4b of the guide sheet 4 is sandwiched between the front film 10 and the side edges 11 and 21 of the back film 20, The three parties 4b, 11 and 21 can be sealed together by heat. Further, when the guide sheet 4 is attached to the inner surface of the back film 20, the guide sheet 4 has an advantage that the appearance is not impaired.
[0028]
On the other hand, as shown in FIG. 4, when the guide sheet 4 is attached to the outer surface of the back film 20, the guide sheet 4 is not turned up or removed from the back film 20. The entire circumference is attached to the outer surface of the back film 20 in a strip shape or entirely. And when the guide sheet 4 is stuck on the outer surface of the back film 20 in this way, the back film 20 is sandwiched between the guide sheet 4 and the cut tape 3 and is cut and torn in a state where a shearing force is applied. Has the advantage of being able to

Further, in the food packaging bag of the present embodiment, as shown in FIG. 1 and FIG. 2, the tab 24 provided on the protruding piece 22 is the opening start point 5, and the opening piece 6 including the opening start point 5 is the opening piece 6. It is stuck.
[0030]
The opening piece 6 is disposed on the inner surface side of the back sheet 20, and is between the seal portion 1 and the opening portion 2 of the back film 20, and is attached to a position close to the seal portion 1. The distal end 6b is attached to a knob 24 provided on the protruding piece 22. The base end portion 6a of the opening piece 6 has the same width as the interval between the pair of guide sheets 4 and 4, and the base end portion 6a is a starting point for tearing the back film 20 at the interval between the pair of guide sheets 4 and 4. Yes. On the other hand, the tip 6b of the opening piece 6 is not attached to the back film 20 around the knob 24 so that the knob 24 can be picked up. Such an opening piece 6 has, for example, an inverted Y shape shown in FIG. 1 or an inverted V shape shown in FIG. 2, and does not specify an inverted U shape or an inverted T shape.
[0031]
Further, as shown in FIGS. 3 and 4, an inner film 7 having substantially the same width as that of the sandwich S is attached to the inner surface of the front film 10. Even if the inner film 7 includes, for example, a sticky material mixed with boiled eggs and mayonnaise as a material of the sandwich S, the sticky material adheres to the inner film 7 so that the surface film 10 is not soiled. Has been.
[0032]
And even if it exists in the packaging bag for foodstuffs of this embodiment, when the opening part 2 is opened in the rectangular shape from the state with which the front film 10 and the back film 20 were piled up, the folding line 26 is a corner | angular part. 27, and a bag-like space (not shown) having a substantially triangular side surface is formed. At this time, the guide sheet 4 is overlaid on the corner 27 of the back film 10.

And the sandwich S is accommodated in the space, the front film 10 and the back film 20 on the opening 2 side are folded into the bottom 8, and the bottom 8 is sealed with an adhesive tape (not shown), Sandwich S is packaged. At this time, the lower edge 4 d of the guide sheet 4 coincides with the bottom 8 of the sandwich S. The guide sheet 4 is also superimposed on the take-out surface 20a and the side surface 20b of the packaging bag to reinforce the back film 20 from the front and side surfaces, and further back from the bottom to the upper end of the packaging bag on the take-out surface 20a. Since the film 20 is superposed on the film 20, the sandwich S is hardly deformed even when an external force is applied to the packaging bag.
[0034]
And in order to eat the packaged sandwich S, the stuck piece 24 and the tip 6b of the unsealed piece 6 are picked and pulled straight downward. At this time, even if the side surface of the packaging bag is grabbed and an external force is applied to the sandwich S, the sandwich S is hardly deformed due to the reinforcing effect of the guide sheets 4 and 4.
[0035]
When the picking piece 24 and the opening piece 6 are further pulled in the direction of the bottom portion 8 directly below, the base end portion 6a of the opening piece 6 tears both sides of the cleavage portion 25 of the back film 20 as shown in FIG. Since the pair of guide sheets 4, 4 are attached to the back film 20, the back film 20 is cleaved with a constant width without being torn from the cleaving portion 25 toward the side edges 11, 21. The Rukoto.
[0036]
Further, even when the pulling piece 24 and the opening piece 6 are not properly pulled and the back film 20 does not follow the inner side edge 4a of the guide sheet 4 and is torn apart, the cut tape 3 At a minimum, the back film 20 is torn to the bottom 8 with the width of the cut tape 3. By opening the packaging bag in this manner, the packaged sandwich S can be reliably taken out.
[0037]
The present invention is not limited to the embodiment of the invention and can be variously modified within the scope of the technical matters described in the claims. For example, the pair of guide sheets 4 and 4 may be provided on the front film 10.
