Description

Sandwich packaging bag

Technical Field

The utility model relates to a wrapping bag for sandwich for placing triangle-shaped sandwich.

Background

In the prior art, a pair of plastic film sheets stacked together is used to form a bag body with three sealed sides, and a sandwich is placed in the bag body to complete the package.

As expected to be widely used, a packaging bag for a triangular sandwich is formed of a pair of sheets made of plastic films stacked together, and the two sides of the packaging bag are narrowed toward the front end, and the three sides are sealed into a bag body by a joining method such as welding and the like and are three-dimensionally unfolded. In this case, the sealing portion of the bag body is provided with a flap portion within the specification of the front end of the thin sheet and a rear end as a reserved opening, and specifically, the sealing portion is composed of a top sealing portion for joining the sheets to each other along a line passing through both side edges and a side sealing portion for joining both side edges of the sheets to each other behind the top sealing portion.

After the sandwich is contained in the packaging bag, the remaining part of the bag body is folded and sealed with an adhesive tape or the like at an opening portion from the rear end of the food to the rear end of the bag body, and the bag is marketed as a sandwich in which the package is completed. Therefore, a consumer purchasing a sandwich must remove the package to remove the food product contained therein. At this time, since it is troublesome to open the sealing portion at the rear end of the food, the consumer often tears the bag body itself to take out the food. However, this method of tearing the pouch by hand is difficult, and therefore many easier methods have been proposed in the prior art.

As a typical example of the above-described easy-to-open method, as described in patent document 1 (japanese patent laid-open publication No. 2017-047940), there is known a sandwich packaging bag having a bag body in which a pair of plastic film sheets are overlapped to form a sheet, and the sheets are joined to each other along a line passing through both side edges to form a top seal portion in the case where a predetermined range of the leading end of each sheet is defined as a flap portion to be reserved; and a pick-up portion formed in a predetermined region above the sheet, the pick-up portion being provided at the center in the width direction of the flap portion of the one sheet, and having one end extending beyond the top seal portion to reach a dicing tape of the pick-up portion and joined to the back surface of the sheet.

SUMMERY OF THE UTILITY MODEL

Technical subject

In the aforementioned prior art, the pick-up portion provided on the flap portion is picked up and pulled up with the fingertip together with the cutting tape, thereby producing an effect of tearing the sheet along the cutting tape and in a prescribed direction, i.e., in the total length direction of the inclined surface of the bag body. In this case, the sandwich can be taken out from the opening formed by tearing.

This alone is not sufficient for the consumer, and therefore attempts are often made to border the opening created by the tear and further spread the bag side-to-side to facilitate removal of the sandwich.

However, since the sheets overlapped with each other on the bag body are firmly joined by the joining line constituting the top seal portion, even if the opening portion formed by tearing the sheets is divided into two, the divided sheets are joined to the sheets overlapped with each other, and therefore, even if the divided sheets are pulled out to the left and right, it is difficult to smoothly spread the sheets due to the restriction of the joining portion, and moreover, there is a risk that the food material filler overflows from the end face of the sandwich and sticks to the hand due to irregular tearing.

Means for solving the problems

An object of the utility model is to provide a solve wrapping bag for sandwich of aforementioned problem.

Therefore, the utility model provides a package bag for sandwich, including the bag body, this bag body is through stacking a pair of plastic film piece as the sheet, under the state of reserving the regulation scope at each sheet front end as the fin portion, make each sheet join each other along the line that passes the both sides limit and form the top sealing to make each sheet both sides limit at top sealing rear join each other and form the side sealing with sealed three sides, the bag body has the tongue piece, the tongue piece has lower extreme and top and is cut into the peninsula shape, makes the fin portion top of one side sheet be equipped with the pick-up portion of certain area, and the cutting tape that one end surpassed the top sealing and reach the pick-up portion simultaneously engage in the back of sheet, the pick-up portion sets up on the position that the tip direction skew of the sheet from the width direction central authorities of sheet, and is equipped with the incision that is used for triggering the sheet tearing towards the width direction central authorities of sheet on the incision of pick-up portion in succession.

Further, the sandwich packaging bag pickup portion is cut into an inverted U-shaped peninsula shape.

Technical effects

According to the technical scheme of the utility model, pick up the portion of will setting up on fin portion and pick up and pull up with the fingertip together with the cutting tape to remove the portion of picking up of one side sheet from the sheet, leave the portion of tearing along the portion of picking up shape on the sheet. Further, at this time, the position where the tear portion is generated is not at the widthwise center of the sheet but at a position shifted in the end direction of the sheet, and a notch for triggering tearing of the sheet toward the widthwise center of the sheet exists on the notch left in the sheet pickup portion.

Therefore, if the sheet on the bag body side is pulled up in the width center direction from the opening portion resulting from the cut-out, since the cut is located at one end of the tear portion remaining on the wing portion, this becomes a trigger point of tearing, and the sheet can be easily opened in the width center direction along the top seal bonding line, thereby obtaining a wide opening portion.

At this time, the tear portion is provided on the flap portion outside the bag body, not on the bag body with three sides sealed, and therefore the sealability of the bag body is not impaired. Thus, a packaged food having a wide opening can be obtained without fear of contamination of foreign matter or deterioration of the food.

Detailed Description

The following describes embodiments of the present invention with reference to the drawings. Fig. 1 to 3 are views showing a sandwich packaging bag according to the present invention, in which a food is packaged in a triangular sandwich. The packaging bag is made of a pair of sheets made of a plastic film having both sides narrowed toward a front end, the sheets are stacked together, and in a state where a predetermined range of the front end of each sheet is left as a flap portion, the sheets are joined to each other by a top seal seam passing through both sides to form a top seal portion, and the sheets are joined to each other at the rear of the top seal portion to form a side seal portion to seal the three sides, thereby forming a bag body.

In the bag body, the triangular sandwich is inserted into the bag body, and the bag body is three-dimensionally unfolded into a plate-like triangle in which the thicknesses of the pair of opposing inclined surfaces are defined by the width of the top seal portion. In this case, as a method of tearing the bag body to take out the sandwich, the dicing tape is bonded to the back surface of one of the side sheets so that one end thereof extends beyond the top seal bonding line to the pickup portion provided in the flap portion. In this bag body, the effect of cutting the sheet in the direction specified by the cutting tape, that is, in the total length direction of the inclined surface of the bag body, is produced by pulling up the pickup portion provided at the flap portion together with the cutting tape with the fingertips.

The bag body has a pair of sheets 10 and 1 made of a plastic film, and a dicing tape 6 bonded on the back surface of the sheet 10 (i.e., the inner surface side of the bag). In addition, the embodiment is also provided with a strip-shaped sheet 5 made of plastic film, which is used for avoiding the stain caused by the contact with the exposed end surface of the food material in the sandwich. The pair of sheets 10 and 1 has a trapezoidal or trapezoid-like shape whose both side edges are narrowed toward the front end, and the bag body can be expanded three-dimensionally after three sides are sealed to constitute the bag body.

In this case, in the bag body molding, the flap portion in which the front end of the sheet is folded within a prescribed range does not constitute the bag body portion, but is reserved as the flap portions 4A and 4B, and the rear end of the sheet is reserved as an opening for placing the food. Specifically, the starting portions of the flap portions 4A and 4B are provided with top seal joint lines 2A and 2B, which join the sheets to each other along the lines passing through both side edges of the sheets, and side seal joint lines 3A and 3B, which join both side edges of the sheets to each other behind the top seal portions, thereby constituting a three-sided seal portion of the bag body. The bag body is unfolded so that the thicknesses of the pair of opposing slopes are defined by the widths of the top seal parts 2A and 2B and the side surfaces form a plate-like triangle by the folds a1 and a1 and B1 and B1, thereby completing the basic shape of the bag body. Further, heat sealing is employed here as the joining method.

In the above-described bag making process, the cutter belt 6 is joined to the back surface of the sheet 10 on one side. The dicing tape 6 is provided so that one end thereof reaches the cut-formed pickup portion S provided on the tab portions 4A and 4B beyond the top- sealing join lines 2A and 2B. The pickup portion S has a certain area above since the tongue piece is reserved with a lower end and is cut above in a peninsula shape, and is obtained by cutting the sheet 10 in an inverted U shape here.

The pickup portion S and the dicing tape 6 reaching the pickup portion are provided at positions shifted from the widthwise center of the sheet 10 toward the end of the sheet (for example, positions shifted toward the left side of the sheet 10 in the drawing). Further, a notch S2 for triggering tearing of the sheet toward the widthwise center of the sheet is continuously arranged on the notch S1 of the pickup S.

In the bag body basically formed through the above steps, after the sandwich is put from the opening at the rear, the remaining part of the bag body from the rear end of the sandwich to the opening at the rear end of the bag body is folded and sealed by an adhesive tape or the like to complete the packaging.

When the above-described sandwich packaging bag is opened, the pickup portion S of the flap portion 4A of the one-side sheet 10 to which the dicing tape 6 is joined is picked up and pulled up, and the dicing tape 6 joined thereto is also pulled up, whereby the sheet is torn along the dicing tape, and an opening portion (shown in fig. 3) formed by the tearing is formed at a position shifted in the sheet end portion direction.

Next, the one-side sheet 10 of the bag body is pulled out in the center direction with the opening portion formed by the cutting as a boundary, and the cut S2 is located at one end of the cut-out portion S1 left in the flap portion 4A, so that this becomes a trigger point of tearing, and the sheet can be easily opened in the width center direction along the top seal bonding line, and a wide opening portion P (see fig. 5) appears.

In the above examples, the sheets 10 and 1 used the antifogging OPP film having a thickness of 40 μm, the tape-shaped sheet 5 used the double-sided heat-sealing OPP film having a thickness of 30 μm, and the dicing tape 6 used the OPP film having a thickness of 30 μm, but this is only one of the embodiments.
