Description

[Detailed Description of the Invention] Industrial Field of Application The present invention relates to a grape packaging bag that can be used to package grapes and to be used for sorting, packing, transporting, or displaying and selling at stores.

Conventional technology As a conventional fruit packaging bag,
Bags made of paper and cellophane paper pasted together, as shown in this issue, or bags made of transparent double-sided film made by heat-sealing synthetic resin films to each other are used.

Problems that the invention aims to solve Conventional fruit packaging bags made by polymerizing and laminating paper and cellophane paper can be used to package grapes, such as in production areas, where they are placed in the bag so that the ripe, well-colored side is visible. There is a tendency for the bad aspects to be hidden, and there is a problem in determining the grade price of the packaged product.Furthermore, when the product is displayed and sold in stores as it is, it can cause complaints and troubles from consumers who have purchased the product.

In addition, in the case of a transparent bag made of double-sided film, the entire packaged grapes can be seen, so the above-mentioned drawbacks are solved, but on the other hand, bags made of double-sided transparent film have poor ventilation and tend to accumulate grape juice, causing cloudiness and stuffiness. Moreover, since both sides are transparent, the color does not match the color of the grapes, making them look dark and dull, and the grapes do not stand out even when displayed in stores. Furthermore, since the double-sided films are bonded together by heat sealing, there are many problems such as it is difficult to speed up bag production and the production capacity is low, and the cost of film is higher than that of paper.

The present invention was created with the aim of solving these problems.

Means for Solving the Problems The structure of the present invention will be explained using FIGS. 1 to 4 corresponding to the embodiments. A trapezoidal synthetic resin film 2 is polymerized and glued to each other along the oblique side 3 and bottom side 4 of one side of the paper 1, and the other side of the synthetic resin transparent film 2 is folded over the side edge 5 of the paper 1 and glued together. an extended portion 6 of a predetermined width extending from the side edge 5;
Either a through hole 7 is formed by folding at the lower end, or V-shaped or W-shaped folded pleats 8, 9 and a through hole 10 are formed inward at the folded portion as shown in FIGS. 6 and 7.
form. Further, a window frame 11 having a grape-shaped, oval, etc. punched hole is attached to the center of the paper 1 with a transparent paper 12 attached thereto.
This is a grape packaging bag structure in which an opening 13 is provided on the upper side of an inverted trapezoidal shape. Reference numeral 14 indicates a microhole formed in the synthetic resin transparent film 2.

Function In the grape packaging bag of the present invention, a bunch of grapes a is inserted through the opening 13 on the upper side, and then the upper side of the opening 13 is bent and sealed with an appropriate fastener 15. The expanded portion 6 or folded folds 8 and 9 of the transparent resin film 2 stand up and the front side bulges out, making it easy to insert and having an inverted trapezoid shape, so there is no extra blank space at the tip like in a triangular bag. The front side has a bulging shape that follows the shape of the grape bunch, while the paper 1 side maintains a nearly flat shape as it is placed on the display stand, and together with the whiteness of paper 1, it brings out the grapes. In addition, the consumer can see not only the surface but also the back side of the grape through the window frame 11 and make a selection and purchase with peace of mind.

Example The following will explain the embodiments shown in the drawings.

1 to 4 show a grape packaging bag showing an embodiment of the present invention, 1 is a fibrous inverted trapezoidal paper, 2 is an inverted trapezoidal transparent synthetic resin film having a width larger than the paper 1, Paper 1 and synthetic resin transparent film 2 are glued together along one oblique side 3 and bottom side 4 by gluing lines 3a and 4a. The other side of the synthetic resin transparent film 2 has a glue line 5 along the other side edge 5 of the paper 1.
It is glued with polymer glue in a. 6 is an extension formed on the other side of the synthetic resin transparent film 2 by folding it back;
Reference numeral 7 indicates a through hole at the lower end formed by folding the paper 1, and 11 indicates a window frame provided in the center of the paper 1. A desired hole such as a grape-shaped hole, an oval shape, or a square shape is punched out, and a transparent film 12 is placed around the punched hole. It is constructed by pasting. 13 is an opening on the upper side of the inverted trapezoidal shape. When manufacturing this bag, as shown in FIG. 8, window frames 11, 11 are punched out at intervals on the left and right sides in the width direction, and transparent paper is pasted from the bottom side of the roll sheet 1.
A wound synthetic resin transparent film base paper 2a having a width larger than that of the base paper is polymerized and glued to the lower surface of the transparent film base paper 2a with cross-shaped gluing lines 3A intermittently attached to the upper surface thereof, and then the transparent film base paper 2a is Gluing lines 5a are provided on the upper surfaces of both sides, and both sides of the base paper 1a are folded and polymerized with glue. Then, the diagonal line is divided in the middle from the diagonal line of the gluing line 3A of the 〓 shape, dividing it into left and right halves, and then the hook shape of the 〓 shape is formed. By cutting in the width direction along the section 4A, the grape packaging bags of the present invention can be obtained two at a time.

FIG. 6 shows a modification of the present invention, in which V-shaped folding pleats 8 are provided inwardly on one side of the inverted trapezoidal shape of the synthetic resin transparent film 2. This can be simply applied by a folder during manufacture as described above. The other configurations are exactly the same as the embodiments described above.

FIG. 7 shows another modification of the present invention, in which a W-shaped folding fold 9 is provided on one side of the inverted trapezoidal synthetic resin transparent film 2, and the other structure is the same as that of the above-mentioned embodiment. It's exactly the same.

Further, the above folding folds 8 and 9 can easily be provided on both sides of the inverted trapezoidal grape packaging bag.

Effects of the invention Since the grape packaging bag of this invention is constructed as described above, when grapes are inserted and packaged, the inverted trapezoidal transparent synthetic resin film, which is more flexible than paper, bulges out to the front side, making the opening large. Since it is an inverted trapezoidal bag that opens, it is easy to insert grapes, and there is no extra blank space at the tip of a rectangular bag like a triangular bag. The grape juice inside is absorbed, and unlike double-sided film, there is no water droplets, cloudiness, or smearing, and the whiteness of the paper makes the grapes stand out, creating a beautiful packaging. Instead, you can see the back side of the grapes through the transparent paper on the window frame, which prevents the tendency of grapes in production areas to hide the bad side of the grapes by wrapping them in the paper side of the bag. In addition to being able to optimize the decision-making and sorting of grapes, they can be packaged, transported, displayed and sold at stores, and since consumers can see the front and back of the grapes before purchasing, they can rest assured that they will not have to worry about complaints or troubles later on. Furthermore, the window frame production capacity can be easily produced using the same methods as window envelopes and bags, and the production capacity does not decrease at all, so it is suitable for speeding up mechanical production and mass production compared to double-sided synthetic resin film bag making using heat sealing. Moreover, the cost of expensive materials such as films can be reduced, and an excellent packaging bag that takes advantage of only the advantages of conventional packaging bags of this type can be provided at a low cost.
