  The present invention does not allow the oil or juice to be attached to the outer surface of the bag when storing sugar beet, and allows the sugar beet to be smoothly stored in the bag. Another object of the present invention is to provide a packaging bag that does not adhere to clothes or clothes.

  It is another object of the present invention to provide a packaging bag that can store a sugar beet containing oil and juice and then absorb the oil to prevent the flavor of the sugar beet from being impaired.

  Another object of the present invention is to provide a packaging bag that can greatly improve the working efficiency of packaging.

  As a means for solving the above-mentioned problems, the present invention is a bag formed of a plastic film and having one end opened, and both ends thereof are separated from each other by a slit over a required length to form a pair of opening pieces. In the present invention, a tear-stop portion made of a notch is formed at the end of the slit.

  In addition, the bag is formed of a plastic film and is open at one end, and is formed with a tearable easy portion capable of tearing so that a pair of opening pieces can be formed over a required length from both sides of the opening. This is because a tear-stop portion made of a notch is formed at the end of the easy portion.

  The bottom of the bag is formed by laminating a hygroscopic sheet on a plastic film, folding the bag in two in the width direction of the bag, heat-sealing both ends to the side edge of the bag, and storing the product of the vegetables The hygroscopic sheet and the bottom plastic film can be stretched to receive the product on the hygroscopic sheet surface and to give the bag self-supporting property.

  The hygroscopic sheet may be a hygroscopic paper or the like, but preferably a non-woven fabric is used in consideration of sealing properties.

  Further, it is desirable to provide a sealing portion to be joined by adhesion, fastener, or the like at an appropriate position on the facing surface of the opening piece, in order to reliably close the opening.

  According to the present invention, when opening a pair of opening pieces when storing the vegetables, both opening pieces can function as a chute and can store the vegetables along the inner surface. Oil or juice does not adhere to the outer surface of the bag, and the outer surface of the bag is prevented from being soiled, and the baggage is prevented from being soiled when being taken home.

  Since the tearing easy part is formed so that a pair of opening pieces can be formed from both sides of the opening to the required length, the pair of opening pieces is opened as described above when tearing the tearing easy part. In this way, both opening pieces can function as a chute so that sugar beet can be stored inside along the inner surface, and if the easy tear portion is not torn, the bag functions as a deep vertical bag. Depending on the size and type of contents to be packaged, two types of functions can be used depending on whether the easy tear portion is torn or not torn.

  Moreover, since the tear stopper part which consists of notches is provided in the root part of the opening piece, even if the opening piece is spread with a strong force, the side edge of the bag will not be torn.

  On the other hand, if a hygroscopic sheet is laminated on the film at the bottom of the bag and folded into two in a mountain fold shape, both ends of the bag are heat-sealed to the side edge of the bag, and the vegetables are stored from the opening of the bag. As a result, the hygroscopic sheet and the bottom film can be flatly spread and received, so there is no need to store prepared foods in a tray or the like and store them in a bag, which enables quick packaging at the store, and the tray. Etc. are not required, so the packaging material cost is low and the sales cost can be reduced.

  In addition, by storing the side dishes, the hygroscopic sheet and the bottom film are spread flat, so that the bottom end of the bag becomes a three-dimensional form without using a bag with a gusset. become.

  Also, when the side dishes are stored, if a pair of opening pieces are opened, both opening pieces function as a chute and can store the side dishes along the inner surface. Can greatly improve.

  FIG. 1 shows a front view of an embodiment of a show bag as a packaging bag according to the present invention, and FIG. 2 shows a perspective view of a state in which an opening is opened when storing sugar beet in the bag.

  The bag 1 is a bag having one end opened by a transparent plastic film, and slits 2 and 2 of a required length are inserted and separated from both ends of the opening end to form a pair of opening pieces 3 and 3. Yes.

  At the end positions of the slits 2 and 2, tear-preventing portions 4 and 4 made of semicircular cutouts are formed, and hand-holding holes 5 and 5 are formed in the opening pieces 3 and 3, respectively. ing. And the sealing part 6 and 6 by the adhesion | attachment or fastener for sealing an opening part is provided in the opposing surface of the opening pieces 3 and 3. As shown in FIG.

  The bottom portion of the bag 1 in the illustrated embodiment is laminated with a non-woven fabric 8 as a hygroscopic sheet on the bottom film 7 as shown in FIG. The bottom of the bag 1 is formed by the heat seals 9 and 9 together with the seal of the side edge 1, and the non-woven fabric 8 and the bottom film 7 are flat as shown in FIG. It spreads in the shape of a dish and catches the side dish 10, and the bottom spreads out into a three-dimensional shape, giving it independence. The hygroscopic sheet is not limited to non-woven fabric, and may be hygroscopic paper.

  Therefore, when the side dish 10 is packaged at the store, if the pair of opening pieces 3 and 3 are opened and the side dish 10 is accommodated between them as shown in FIGS. The inner surface of 3 becomes a chute shape, and the side dish 10 is induced | guided | derived and can be accommodated smoothly. As a result, oil or juice does not adhere to the outer surface of the bag 1 and the outer surface of the bag 1 is not soiled.

  As shown in FIG. 4 (B), the stored side dish 10 can be stored in a stable state since the nonwoven fabric 8 and the bottom film 7 are flatly stretched and received, and the oil content of the side dish 10 etc. Is absorbed by the non-woven fabric 8 so that the side dish 10 does not become sticky, or even if it becomes sticky, the degree of stickiness is reduced and the flavor is prevented from being impaired.

  Moreover, since the non-woven fabric 8 and the bottom film 7 are stretched by storing the sugar beet 10, the lower end of the bag 1 is widened to give self-supporting properties, and the form becomes easy to handle.

  After storing the prepared food 10, the opening pieces 3 and 3 are closed by the sealing portions 6 and 6 as shown in FIG.

  Next, another embodiment of the packaging bag according to the present invention will be described with reference to FIG. The bag 11 shown in FIG. 5 has a perforation 12 as an easy tearing portion. The perforations 12 are formed from the opening to both sides at a required length, and the perforations 12 are separated when the perforations 12 are torn to form a pair of opening pieces 13. When the perforation 12 is not torn, the pair of opening pieces 13 has a cylindrical shape, and the bag 11 can function as a deep vertical bag. In this case, it is convenient when the wide opening of the opening is not required but a long depth of the bag is required. When the perforation 12 is torn, the bag 11 can function in the same manner as the bag 1 shown in FIG. Thus, the bag 11 can use two types of functions depending on the size and type of contents to be packaged depending on whether the perforation 12 is torn or not.

  In addition to the perforation 12, any easy tearing portion may be used as long as it can be easily torn, such as a narrow tape.

  In the above description, a show bag has been described as an example of one form of a packaging bag. However, the packaging bag of the present invention is not limited to a show bag, and may be a packaging bag for transport such as a shopping bag.
