In general, grapes are a fruit with good flavor and rich juice. It is mainly used as a raw fruit, and is also used in beverages, brewing, jam, dried fruit, and canned food.

Immediately after harvest, these grapes are put in a packaging bag and box-packed, and then go through a relatively long-term storage and distribution stage in a refrigerated state, and are sold to final consumers.

Therefore, the packaging bag for grapes must satisfy the following two requirements.

First, it is not necessary to transfer the grapes in the packaging bag to a separate container for the sale of grapes, and the condition of the grapes contained in the packaging bag should be visible from the outside.

Second, even during long-term storage and distribution of grapes, high air permeability must be maintained so that the quality of grapes does not deteriorate due to condensation caused by moisture in the bag.

In order to satisfy the above two requirements for packaging bags for grapes, Prior Art No. 20-0343502 "Individual Packing Bags of Grape Clusters" and Prior Art No. 20-2017 Domestic Utility Model Publication No. 20-2017 -0001431 "Wrapper for green grapes with antibacterial and anti-humidity function" is disclosed.

That is, according to the prior art 1 and the prior art 2, the state of the grapes can be visually checked from the outside using a transparent vinyl material, and a plurality of air holes are formed in the transparent vinyl to increase the air permeability.

However, in the prior art described above, if the diameter of the ventilation hole is formed to be large in order to simply increase the air permeability, damage to the packaging bag, such as the transparent vinyl is easily torn, occurs, and in order to prevent such damage, the diameter of the ventilation hole is reduced. If it is formed small, there is a problem in the prior art that it is not possible to obtain a desired level of air permeability from the packaging bag, which causes deterioration in quality in the process of storage and distribution of grapes.

An embodiment of the present invention will be described in detail with reference to the accompanying drawings as follows.

As shown in Figs. 1 to 6, the packaging bag for grapes according to the present invention includes a folded lower portion 10 formed by folding a single rectangular wrapping paper 1, and one edge of both sides of the folded lower portion 10. An adhesive side (20) formed by bonding only the adhesive side (20), an open side (30) formed on the opposite side of the adhesive side (20), and an open upper portion (40) formed on the opposite side of the folded lower part (10) In the packaging bag, the adhesive side portion 20 may be achieved by forming the non-adhesive portion 21 on the open upper portion 40 opposite to the folded lower portion 10 .

That is, the packaging bag for grapes according to the present invention is formed by folding one rectangular wrapping paper 1 and attaching it with an adhesive, and has four sides.

The wrapping paper 1 is preferably made of a paper material that is not easily torn while having excellent breathability, and the adhesive used in the production of the packaging bag for grapes of the present invention will preferably be a natural adhesive that is harmless to the human body.

The four sides forming the packaging bag for grapes have a lower folded lower portion 10, an adhesive side 20 on the left and an open side 30 on the right, as shown in FIGS. 1 and 2 when viewed from the front, and It consists of an upper open upper part (40).

Therefore, the packaging bag for grapes of the present invention is sealed in an L shape by folding or bonding two sides, and the remaining two sides are opened.

First, the folded lower portion 10 is a portion formed by folding the wrapping paper 1 and is sealed without using a separate adhesive.

In addition, the adhesive side portion 20 is sealed by bonding one side of the front side and the back side of the folded wrapping paper 1, and the left side in FIGS. 1 and 2 to each other using an adhesive.

In addition, the open side 30 is an open side opposite to the adhesive side 20 and opposite to each other in the folded wrapping paper 1, and can be opened when you want to put grapes as shown in FIG. 5, and the packaging for grapes After the grapes (2) are put in the bag, the side is tied using a separate wire string (3) as shown in FIG.

Lastly, the open upper part 40 is the opened side opposite to the folded lower part 10 in the folded wrapping paper 1, and can be opened when you want to put grapes as shown in FIG. 5, and FIG. 6 A portion of the grapes (2) contained in the packaging bag for grapes is exposed as such.

Accordingly, when viewed from the front, the packaging bag for grapes according to the present invention has a folded lower portion 10 and an open upper portion 40 that are long sides in the horizontal direction, and an adhesive side 20 and an open side that are short sides in the vertical direction. It is formed in an approximately rectangular shape having (30), and for this purpose, it may be made of one wrapping paper 1 that is approximately square as shown in FIG. 4 .

4 , the front side will form the inner surface of the packaging bag for grapes, and the back side will form the outer surface of the packaging bag for grapes.

In particular, in the present invention, there is a technical feature in that the non-adhesive part 21 is formed near the open upper part 40 in the adhesive side part 20 .

This non-adhesive part 21 is located on the above-described adhesive side 20 in the packaging bag for grapes, but the front and the back are not attached to each other because the adhesive is not applied. In particular, as shown in FIG. When a force is applied in the longitudinal direction to open or open the upper part 40, the non-adhesive part 21 naturally spreads back and forth to disperse and relieve the applied force.

Accordingly, in the packaging bag for grapes, the open top 40 is effectively prevented from being torn or the adhesive portion of the adhesive side 20 is peeled off, and the open top 40 is naturally induced to open outward.

Additionally, in the present invention, it will be preferable that two seam allowances 41 and 42 of two folds are formed in the open upper part 40 of the wrapping paper 1 by folding the end of the wrapping paper 1 inward.

These two seam allowances 41 and 42 are, as shown in FIG. 5, in the packaging bag for grapes, the seam allowance 41 formed on the open upper portion 40 of the front side and the open upper portion 40 of the rear surface. It will be the seam allowance (42).

As shown in FIG. 4 , the seam allowances 41 and 42 are formed by applying an adhesive to both upper and lower sides of the wrapping paper 1 and then folding both upper and lower ends inward.

In this way, in the packaging bag for grapes of the present invention, the two-fold seam allowances 41 and 42 are formed on the front and back surfaces of the open upper portion 40, respectively, to prevent the open upper portion 40 from being torn by external force. In addition to this, the open upper part 40 is induced to continuously maintain a straightened state without crying.

As a result, even when the open top 40 and the open side 30 are spread apart to put the grapes 2 in the packaging bag for grapes of the present invention as shown in FIG. 5 , the open top 40 is straightened will allow you to maintain

Of course, as shown in FIG. 6 , in the state in which the grapes 2 are contained, the edges do not cry due to the seam junctions 41 and 42 described above compared to the single fold, as if the grapes 2 are contained in a separate display container. It gives an impression to consumers.

Additionally, in the case of printing two printing lines 50 along the open upper part 40 near the open upper part 40 of the front and back surfaces of the packaging bag for grapes in the present invention, as illustrated in FIG. The printing line 50 makes it look like an entrance edge of a container for display, which may give consumers a higher aesthetic sense.

In addition, in the packaging bag for grapes of the present invention, it is preferable that the heights of the front seam allowance 41 and the rear seam seam end 42 of the wrapping paper 1 do not coincide with each other as shown in FIG. 3 .

In general, after the production of packaging bags for grapes, a plurality of packaging bags for grapes are stacked and stored or transported to a work space.

Then, when the operator puts the harvested grapes (2) in the packaging bag for grapes of the present invention, friction between the front and back surfaces of the open upper portion 40 in the packaging bag for grapes with the thumb and index finger, as shown in FIG. The two ends of the open upper part 40 are spread apart.

At this time, if the seam allowances 41 and 42 are not formed, or the ends of the open upper part 40 coincide with each other, the operator experiences a lot of difficulty in the operation of spreading the open upper part 40, and the grape ( 2) The work time for packaging is long.

However, in the packaging bag for grapes of the present invention, since the two seam allowances 41 and 42 formed on the open upper 40 of the front and back are formed with a height difference from each other as shown in FIG. By being able to spread the open upper part 40 of the packaging bag as shown in FIG. 5, it is possible to greatly improve the efficiency of the operator's packaging operation.

In addition to this, in the present invention, the folded lower portion 10 is preferably folded in and out three times to have a W-shaped cross section.

In FIG. 4 , a portion folded inward is indicated by a dotted line, a portion folded outward is indicated by a dashed-dotted line, and a hatching line is indicated in a portion to which an adhesive is applied.

Accordingly, in the packaging bag for grapes of the present invention, a cross section of a substantially W-shape is formed in the folded lower portion 10 as shown in FIG. 5 , and as a result, the grape packaging bag containing the grapes 2 is folded The lower portion 10 can be spread over a relatively large area.

Therefore, even if the packaging bag for grapes of the present invention containing the grapes 2 is placed on a horizontal surface, it is possible to maintain a stable standing state without collapsing.

Although the configuration and operation of the packaging bag for grapes according to the present invention have been described so far, the manufacturing process of the packaging bag for grapes will be described based on the apparatus for manufacturing the packaging bag for grapes according to the present invention.

As shown in FIGS. 7 and 8, the apparatus for manufacturing a packaging bag for grapes according to the present invention is an adhesive application roller 100 for intermittently applying an adhesive according to rotation to both edges in the width direction of the continuously supplied wrapping paper 1 Wow; a folding roller 200 having a width narrower than the width of the wrapping paper 1 and rotating; It consists of a plate and is located on both sides of the folding roller 200, and the both end surfaces 210 of the folding roller 200 and an upright part 310 for erecting both ends of the wrapping paper 1 in the width direction at right angles; a seam allowance blade 300 having a wider width than the upright portion 310 and including folding portions 320 for folding both edges of the wrapping paper 1 in the width direction erected at a right angle; It is preferable to include a pressure roller 400 for pressing both edges in the width direction of the wrapping paper 1 that has passed through the seam allowance blade 300 .

7 and 8 , the wrapping paper 1 is supplied from the right side in the drawing and will proceed continuously to the left, and proceed in the continuous supply direction shown in FIG. 4 .

First, in the production of a packaging bag for grapes using the apparatus for manufacturing a packaging bag for grapes according to the present invention, when the wrapping paper 1 in a state wound on a roll is supplied, the printing line ( 50) and the name of the company, etc. are printed.

Thereafter, the adhesive is repeatedly applied to the portion indicated by the hatched line in FIG. 4 using the adhesive application roller 100 , and in FIG. 7 , reference numeral 101 denotes a roller corresponding to the adhesive application roller 100 .

At this time, the application of the adhesive is not applied to the entire area indicated by the hatched line in FIG. 4 , but the adhesive is applied to the point repeated while the adhesive application roller 100 is rotated and applied pressure to the entire area indicated by the hatched line in FIG. 4 . to make it stick.

When the adhesive is applied to the seam allowance ends 41 and 42 to be formed on both sides of the continuously supplied wrapping paper 1 as described above, after passing through the guide roller 500, the folding roller 200 and the seam allowance blade 300 The seam-joint ends 41 and 42 of the wrapping paper 1 are folded by using.

At this time, the width of the folding roller 200 is formed to correspond to the width of the wrapping paper 1 excluding the seam weld ends 41 and 42 in the wrapping paper 1, and in FIG. 7, reference numeral 201 denotes the folding roller As a roller corresponding to (200), the width of this roller is formed to be wider than the width of the folding roller (200).

In addition, the seam allowance blade 300 is made of a long metal plate having a predetermined thickness, and an upright portion 310 and a folding portion 320 are formed, and the width of the folding portion 320 is the upright portion 310 ) is formed with a wider width.

The upright portion 310 of the seam allowance blade 300 is positioned adjacent to both sides of the outer end face 210 of the folding roller 200 as illustrated in FIG. 8 .

At this time, the seam allowance blade 300 is fixed to the pedestal 301 located on its lower side by a separate fastening means 302, and the position of the seam allowance blade 300 can be adjusted by loosening the fastening means 302. will be.

Accordingly, as the wrapping paper 1 proceeds from right to left in FIG. 8 , in a state where the folding roller 200 presses the wrapping paper 1 inside the seam junction ends 41 and 42 , the seam junction end 41 , 42) are both ends of the wrapping paper 1 as indicated by A in FIGS. 7 and 8 by the upright portion 310 of the seam allowance blade 300, that is, the seam seam ends 41 and 42 to be formed later. will raise the

The both ends of the wrapping paper (1) erected in this way are gradually reversed until the folding part 320 of the seam allowance blade 300 starts as it continues to the left, and when the folding part 320 is reached, the reverse phase is completely completed. Seam allowances 41 and 42 are formed.

At this time, reference numeral 301 is a pedestal for supporting the lower portion of the seam allowance blade 300, and has a fine gap between the pedestal 301 and the seam allowance blade 300 so that the seam allowance ends 41 and 42 are completely folded.

After that, the seam allowance ends 41 and 42 of the wrapping paper 1 coming out between the seam allowance blade 300 and the pedestal 301 are directly guided between the pressure roller 400 and the corresponding roller 401 and pressurized with high pressure. , the adhesive applied to the inside is spread evenly and adhered to complete the seam allowances 41 and 42.
