Description

  The present invention relates to a packaging bag used when selling sugar beet.

  When selling tempura, various fried foods, and other side dishes including oil and soup at supermarkets, convenience stores, and department store food stores, side dishes are stored in plastic film sachets called show bags. To be provided to customers.

  When packaging the above-mentioned beet, generally, the beet is placed in a boat-shaped paper tray and stored in a show bag or a non-woven fabric for oil draining and then stored in a packaging form. It has been.

  Therefore, in the conventional show bag, since a flat tray or non-woven fabric is put in the bottom of the show bag, the show bag itself is a square bottom bag with a gusset, and the tray or non-woven fabric is placed in this to give self-supporting properties. Structure is adopted.

However, the use of the square bottom structure for the show bag itself as described above has a problem that the manufacturing process becomes complicated and the amount of the constituent material of the bag increases, resulting in a high cost.
JP 2001-199451 A

  The present invention can provide independence without having a square bottom structure, and it is not necessary to store prepared foods after preparing trays and nonwoven fabrics, reducing labor at the time of sale and saving materials. An object of the present invention is to provide a packaging bag that can reduce costs.

  As a means for solving the above-mentioned problems, the present invention provides a bag formed of a plastic film and having an opening at one end, and a bottom part of the bag is laminated with a hygroscopic sheet on the plastic film and folded in two in the width direction of the bag. Both ends of the bag are heat sealed to the side edges of the bag, and the hygroscopic sheet and the plastic film on the bottom are flattened when the side dish is stored. There is a thing to be given sex.

  Although an appropriate material can be used as the hygroscopic sheet, it is most preferable to use a non-woven fabric in terms of sealing properties, hygroscopicity, odorlessness, and the like.

  The plastic film constituting the bag is preferably made of a transparent film so that the contents can be seen through.

  Furthermore, it is desirable to provide a sealing portion that is bonded to the inner surface of the mouth portion of the bag by adhesion, fastener, or the like in order to reliably close the opening.

  According to the present invention, since the hygroscopic sheet and the bottom film can be flatly received by storing the commodities of the side dish from the opening of the bag, the side dish is stored in the tray etc. This makes it possible to quickly wrap the product at a storefront, backyard, or the like, thereby shortening the waiting time of the customer.

  Further, since a tray or the like is not required, the packaging material cost can be reduced, and the sales cost can be greatly reduced.

  Furthermore, by storing the product, the hygroscopic sheet and the bottom film can be flattened so that the lower part of the bag becomes a three-dimensional form without being fitted with a gusset, and can be placed upright after packaging. It can be a packaging bag that is extremely convenient in handling.

  FIG. 1 shows a form of a show bag as a packaging bag according to the present invention when stored, FIG. 2 is a front view when not in use, FIG. 3 (A) is a central longitudinal sectional view, and FIG. The center longitudinal cross-sectional view of (FIG. 1) is shown.

  The bag 1 is formed of a transparent heat-sealable plastic film, and the bottom of the bag 1 is laminated with a non-woven fabric 3 as a hygroscopic sheet on the bottom film 2 and folded into two in the width direction of the bag 1 by mountain folding. Is integrated with heat seals 4 and 4 together with the seal of the side edge of the bag 1 to form the bottom of the bag 1, and the non-woven fabric 3 and the bottom film 2 are stored by storing products such as sugar beet from the mouth 1 a. Is flattened and catches the product, and the bottom spreads out into a three-dimensional shape, giving it independence.

  When the bag 1 is manufactured, the bag 1 can be easily manufactured by the steps shown in FIGS. 4 (A) to 4 (D).

That sends a clear plastic film 5 having a predetermined width L ₁ in the direction of arrow P, and sends by laminating nonwoven fabric 3 having the required width L ₂ in the center.

The plastic film 5 and the nonwoven fabric 3 was two folding mountain fold shape at the center 6 of the region and the plastic film 5 and the nonwoven fabric 3 are laminated with cutting width L ₃ corresponding position of the bag 1 (FIG. 4 (B Next, the other side of the plastic film 5 is folded (shown in FIG. 4C).

  Thereafter, heat sealing 4 and 4 are applied to both side edges to seal the side portions, whereby the bag 1 having the mouth 1a opened can be formed (shown in FIG. 4D).

  1 to 3 show a case in which a sealing portion 7 for fastening the mouth portion 1a of the bag 1 with a fastener or adhesive glue is provided.

  Therefore, if the side dish is stored from the mouth 1a of the bag 1 at the store, the nonwoven fabric 3 and the bottom film 2 that are hygroscopic sheets are stretched and received in a flat shape, so that they can be stored in a stable state and the side dish. Since the oils and juices are absorbed by the nonwoven fabric 3, the flavor of the sugar beet is not impaired.

  Moreover, since the non-woven fabric 3 and the bottom film 2 are stretched by storing the sugar beet, the lower end of the bag 1 is spread and flattened, so that it becomes self-supporting and easy to use in handling.

  The hygroscopic sheet is not limited to the non-woven fabric 3, but may be hygroscopic paper or other materials.

  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. .

  In addition, the term hygroscopic sheet used in the description of the present invention does not mean that only moisture can be absorbed, but drip or tempura that exudes from fish or meat other than moisture. It means that oil such as can be absorbed.

  Further, in the above description, the transparent film has been described as an example so that it can be seen through as a plastic film constituting the packaging bag. However, the packaging bag of the present invention may be a film whose both sides are transparent. Only the transparent film may be used, or the film may be an opaque film on both sides so that the inside cannot be seen through and the inside can be seen only from the opening.

  Moreover, in the above-mentioned description, although the example with which the sealing part 7 is provided was shown as one form of a packaging bag, the case where it does not have the sealing part 7 as a packaging bag of this invention may be sufficient.

The perspective view which shows the state which opened the bottom part of one Embodiment of the packaging bag by this invention. The front view at the time of unused. (A), (B) is each schematic sectional drawing at the time of the unused and the time of use. (A)-(D) are process explanatory drawing which shows an example of the method of manufacturing the packaging bag by this invention.
