Description

The present invention relates to a packaged food such as a sandwich housed in a plastic film packaging bag.

  A pair of sheets made of plastic film with both sides narrowing toward the tip are overlaid, and each sheet is attached by a top sealing adhesive line that crosses both sides while leaving a predetermined range of the tip of each sheet as a tab portion. A bag body in which three sides are sealed by a top sealing part in which sheets are bonded together and a side sealing part in which both sides of each sheet behind the top sealing part are bonded is known as a sandwich packaging bag ( Patent Document 1).

In the above known invention, by inserting a triangular sandwich into the bag body, the bag body is three-dimensionally expanded into a plate-like triangle in which the thickness of a pair of opposed slopes is defined by the width of the top sealing portion. . In this case, as a means for tearing the bag body for taking out the sandwich, any sheet is cut so that one end of the cut tape extends beyond the adhesive line for sealing the top portion and reaches the raised piece by the notch provided in the tab portion. It is glued to the back side. In this known invention, the sheet is cut along the direction defined along the cut tape, that is, along the entire length of the slant surface of the bag body, by pulling the pull-up piece provided on the tab portion with the fingertip and pulling it up. Produces the effect.
Japanese Utility Model Publication No. 7-8238

  In the packaged sandwich using the packaging bag, since the sheet is cut along the entire length of the inclined surface of the bag body, the sandwich can be pulled out from the window portion generated by the cutting.

  By the way, it is not enough for an actual consumer, and there are many attempts to make it easier to take out the sandwich by spreading the bag body to the left and right with the window part generated by cutting as a boundary.

  However, the overlapping sheets of the bag are strongly bonded to each other by the top sealing adhesive line, and even if one sheet is divided into two by the window generated by cutting, the divided sheet is still Because it is bonded to the overlapped sheet, even if the divided sheet is pulled to the left or right, it is restricted by the bonded part and does not spread well, but conversely, the contents that protrude from the end face of the sandwich by being torn irregularly There was a risk of sticking to hands.

  This device was created for the purpose of providing a packaged food that eliminates the above-mentioned problems of the prior art, and is used for sealing the top part of a pair of sheets made of plastic film and crossing both sides. By the top sealing part which bonded each sheet in the state which left the tip predetermined range of each sheet as a tab part by the adhesion line, and the side sealing part which bonded both sides of each sheet behind the top sealing part Consists of a bag with 3 sides sealed, and the cut tape is bonded to the back of any sheet so that one end of the cut tape extends beyond the adhesive line for sealing the top and reaches the raised piece by the notch provided in the tab part. In a packaged food made of a solid food that expands the bag body into a plate-like three-dimensional shape along its outer shape by being inserted into the bag body having the structure described above, and by using a tab portion cut tape On either side of the Ri-up appointment place, characterized in that the cutout for providing an opportunity for tear arranged close to the bond line for top sealing.

  In addition, as a second invention here, in the packaged food, on both sides of the portion of the tab portion to be cut with the cut tape, the width of the adhesive line for top sealing is narrowed to create a step, and the step portion is torn. Also disclosed is a device in which a cut-out portion is provided to provide a trigger.

  Therefore, according to the present invention, when one sheet of the bag body is pulled left and right with the window portion generated by the cutting as a boundary, the cut-out portion is attached to both sides of the portion to be cut by the cut tape of the tab portion. Since the sheet is arranged close to the sheet, it becomes a trigger for tearing, and the sheet can be easily torn along the top sealing adhesive line and opened to the left and right, and a wide opening appears. 6 and 7).

  In this case, since the cutout portion is not provided in the bag body in which the three sides are sealed, but is provided in the tab portion outside the bag body, the sealing performance of the bag body is not impaired. Therefore, it is possible to realize a packaged food product that can obtain a wide opening without worrying about the mixing of foreign substances or the deterioration of the food product.

  On the other hand, according to the second device in which the width at the front and rear of the adhesive line for sealing the top portion is narrowed to form a step and a cutout portion is provided to give a trigger for tearing to the stepped portion, As the stress when one sheet of the bag body is pulled to the left and right is concentrated on this stepped portion, a more effective tear triggering action occurs.

  Hereinafter, specific embodiments of the present invention will be described with reference to the accompanying drawings. Here, a triangular sandwich is taken as an example of food, but it goes without saying that food is not limited to this. FIG. 2 shows each member constituting the bag P used in the packaged food of the present invention in an unfolded state. This bag is composed of a pair of sheets 1A and 1B made of plastic film and a cut tape 10 bonded to the back surface (the inner surface side of the bag) of the sheet 1A. The pair of sheets 1A and 1B are formed in a trapezoidal shape or a trapezoid-like shape in which both sides are narrowed toward the tip, and after three sides are sealed to form a bag, the bag is expanded three-dimensionally.

  In this case, a predetermined range of the leading end of the sheet is left as the tab portions 4A and 4B that do not form the bag portion in configuring the bag body, and the rear end of the sheet is left as an opening for inserting food. Specifically, the top sealing bonding lines 2A and 2B are provided for bonding the sheets to each other along a line crossing both sides of the sheet at the starting point of the tab portions 4A and 4B. By providing side surface sealing portions 3A and 3B in which both side sides of each rear sheet are bonded to each other, the three side sealing portions of the bag body are formed. And with the folds A1, A1 and B1, B1, the thickness of the pair of opposing slopes A and B is defined by the width of the top sealing portions 2A and 2B, and the side faces C and C are formed into a plate-like triangle forming a triangle. By expanding the bag body, the basic shape of the bag body is completed (see FIG. 1). In the embodiment of the present invention, a heat seal is adopted as the bonding means.

  In the bag making step, the cut tape 10 (here, a plastic film is used) is bonded to the back surface of one sheet 1A. The cut tape 10 is arranged so that one end of the cut tape 10 extends beyond the top sealing adhesive lines 2A and 2B and reaches the raised piece S by the notch provided in the tab portions 4A and 4B. The pulling piece S is obtained by cutting the sheet 1A into a U shape here, but the shape is not limited to this, for example, a pair of cuts having a wider interval than the starting end of the cut tape at the sheet end. Of course, it may be provided. Needless to say, the easy opening means using the cut tape and the raising piece may be arranged on the 1B side instead of the sheet 1A.

  FIG. 3 is a diagram showing details in the vicinity of the tab portion. In this embodiment, the wide portion D2 is obtained by narrowing the front and rear width of the top sealing adhesive line 2A (2B) to the narrow portion D2 on both sides of the portion to be cut by the cut tape 10 of the tab portion 4A (4B). Are provided with cut-out portions 6 and 6 for giving a trigger for tearing to the step portion. In this embodiment, the cutout portions 6 and 6 are a plurality of short linear cutouts penetrating the sheet 1A, but the number may be one, and the shape and number are not limited to those shown in the figure. Of course.

  Further, in this embodiment, a strip 5 made of a plastic film to be in contact with the end face of the inserted food is disposed on the back surface of the sheet 1B.

  After the food P such as a sandwich is inserted into the bag body P whose basic shape has been completed by the above steps, for example, from the rear opening, the excess portion of the bag body that hangs from the food rear end to the bag rear end opening is folded. Sealing with adhesive tape or the like completes packaging.

  When opening the bag, the cut tape adhered to the tab 4A of the sheet 1A to which the cut tape 10 is bonded is picked up and pulled up (see FIG. 4). As the sheet is pulled up as well, the central portion of the sheet is cut off while being cut along the cut tape (see FIG. 5).

  Next, if one sheet 1A of the bag body is pulled to the left and right with the window portion generated by the cutting as a boundary, the cut-out portions 6 and 6 trigger the sheet to be easily torn along the top sealing adhesive line 2A. It can be opened to the left and right, and a wide opening appears (see FIGS. 6 and 7). FIG. 7 shows a state in which the sheet 1 </ b> A is pulled apart at the rear end portion of the bag body P and completely opened.
