Description

  The present invention generally relates to a fruit and vegetable packaging bag, and more particularly to a fruit and vegetable packaging bag that is used for packaging fruits and vegetables such as bananas and broccoli and displaying them in a store.

  Conventionally, various forms of goods have been proposed as packaging bags for packaging bananas and displaying them in stores.

  For example, in JP 2010-100306 A (hereinafter referred to as Patent Document 1), as a packaging body that can be packaged while maintaining air permeability without impairing the form, an appropriate interval according to the length of the banana. A packaging body in which a plurality of vent holes are formed side by side is described.

  Further, for example, in Japanese Patent No. 3154441 (hereinafter referred to as Patent Document 2), as a package that can maintain freshness by allowing the banana to continue its breathing action in an appropriate oxygen atmosphere, there are many fine objects. A package in which a perforated hole is formed is described.

  Furthermore, for example, in Japanese Patent Application Laid-Open No. 2005-219964 (hereinafter referred to as Patent Document 3) and Japanese Patent Application Laid-Open No. 2007-22586 (hereinafter referred to as Patent Document 4), in order to package irregular shaped fruits such as bunch bananas, etc. Describes an unshaped fruit packaging bag in which a transparent resin film and a nonwoven fabric are combined.

JP 2010-100306 A Japanese Patent No. 3154441 JP 2005-219964 A JP 2007-22586 A Japanese Patent Laid-Open No. 11-240579

  However, in the package described in Patent Document 1, ethylene gas generated from the banana can be released from the plurality of vent holes, but oxygen gas is introduced into the package body from the outside of the package through the plurality of vent holes. Therefore, there was a problem that the banana was oxidized and the quality deteriorated. In addition, there is a problem that insects enter the package through a plurality of vent holes.

  In the package described in Patent Document 2, oxygen gas is difficult to enter the package through a large number of fine holes from the outside of the package, so that deterioration of quality due to banana oxidation can be suppressed, and the package Insects can be prevented from entering the inside of the packaging, but there is a problem that the ethylene gas generated from the banana tends to accumulate inside the packaging.

  In the packaging bags described in Patent Document 3 and Patent Document 4, ethylene gas generated from the banana is released out of the packaging bag through a breathable nonwoven fabric. However, since the packaging bag is configured by combining the transparent resin film and the nonwoven fabric, there is a problem that the structure of the bag is complicated and the manufacturing cost increases.

  The functional film material described in Patent Document 5 is suitable for storing, for example, vegetables, mushrooms, and the like as stored items that generate gas. It is provided in the arrange | positioned welding part. For this reason, when storing bananas or the like having bunched parts, it is difficult to quickly exhaust ethylene gas generated from bananas or the like out of the bag through the gas zone or the exhaust hole. was there.

  Accordingly, an object of the present invention is to prevent outside air such as air containing oxygen gas or insects from entering the bag, and gas generated from fruits and vegetables such as bananas and broccoli as bags. It is providing the packaging bag for fruit and vegetables which can be discharged | emitted outside.

  The fruit and vegetable packaging bag according to the present invention is a fruit and vegetable packaging bag made of two synthetic resin films, and includes an insertion opening, a bottom, one side end, and the other side end. The insertion port portion is composed of an opening formed by overlapping the edges of two films without being continuously welded, and is used for inserting fruits and vegetables. At the bottom, there are a plurality of aperture portions formed without overlapping and welding a part of two films, and a plurality of aperture portions formed by overlapping and welding a part of two films. Has been placed. One side end portion extends from the insertion opening portion toward the bottom portion, and is formed by continuously welding the end edges of the two films overlapping each other. The other side end portion extends from the insertion port portion toward the bottom portion and is disposed on the side facing the one side end portion, and is formed by continuously welding the end edges of the two films overlapping each other. Opening / closing rows formed of a plurality of aperture portions and groups of aperture portions, in which one aperture portion and one aperture portion are alternately arranged in the direction in which the edge of the bottom portion extends, include at least two rows, the bottom portion It is arranged along the edge. In at least two open / close rows, one aperture portion and one aperture portion are arranged at different positions in the direction from the bottom toward the insertion port.

  Using the packaging bag for fruits and vegetables of the present invention, fruits and vegetables are stored in the packaging bag from the insertion opening. Thereafter, the insertion port is sealed with a seal or the like. In this state, the fruits and vegetables are displayed in stores. At this time, when a gas such as ethylene gas is generated in the bag from fruits and vegetables such as bananas and broccoli as stored items, the bag is in a sealed space, so that the bag swells and the internal pressure of the bag increases. With this pressure, ethylene gas is discharged out of the bag through a plurality of openings. For this reason, the freshness and quality of fruits and vegetables can be maintained without being adversely affected by the gas generated by the fruits and vegetables. For example, when a banana is stored, the banana can be prevented from becoming black.

  Further, the pressure of the gas generated inside the bag can prevent outside air such as air from entering the bag through a plurality of openings. For this reason, since oxygen gas does not enter the inside of the bag, it is possible to prevent the fruits and vegetables from being oxidized. Thereby, it is possible to maintain the taste and freshness without rotting the fruits and vegetables.

  Further, while the gas is generated from the stored item, the internal pressure is higher than the external pressure, but when the gas is not generated, the internal pressure and the external pressure are in an equilibrium state. Also at this time, since the gas does not enter and exit through the plurality of opening portions, it is possible to prevent outside air such as air from entering the inside of the bag through the plurality of opening portions.

  In particular, in the fruit and vegetable packaging bag of the present invention, an open / close row consisting of a group of a plurality of aperture portions and aperture portions is positioned at the bottom of the bag. When a banana, broccoli or the like having an expanded portion of the tuft is stored, the expanded portion can be positioned at the bottom of the bag. For this reason, it becomes easy to discharge | emit rapidly the ethylene gas generated from a bunch of bananas etc. out of a bag through a plurality of opening portions.

  In addition, since at least two open / close rows have one opening portion and one closing portion arranged at different positions in the direction from the bottom toward the insertion port, outside air such as oxygen gas can flow inside the bag. In addition to preventing entry, insects can be effectively prevented from entering the bag.

  As described above, according to the present invention, it is possible to prevent outside air such as air containing oxygen gas and insects from entering the inside of the bag, and it is generated from fruits and vegetables such as bananas and broccoli as stored items. Gas can be discharged out of the bag.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  As shown in FIGS. 1 to 3, the banana packaging bag 1 is an example of a package for fruits and vegetables, which is a packaging bag for fruits and vegetables made of two synthetic resin films 1 a and 1 b. For example, as the synthetic resin films 1a and 1b, an OPP (oriented polypropylene; stretched polypropylene) film having a thickness of 25 μm and subjected to an antifogging treatment is used. A (polypropylene) film, a PE (polyethylene) film, or the like may be used.

  The banana packaging bag 1 includes an insertion port portion 11, a bottom portion 12, one side end portion 13, and the other side end portion 14.

  The insertion port 11 is composed of an opening formed by overlapping the edges of the two synthetic resin films 1a and 1b so as not to be continuously welded, and is used for inserting fruits and vegetables. On the bottom portion 12, a plurality of apertures 121 formed by overlapping a part of the two synthetic resin films 1a and 1b and not being welded, and a part of the two synthetic resin films 1a and 1b overlap. A plurality of closed hole portions 122 formed by welding are disposed.

  The one side end portion 13 extends from the insertion port portion 11 toward the bottom portion 12 and is formed by continuously welding the end edges of the two synthetic resin films 1a and 1b. Further, the one side end portion 13 is formed so as to bend toward the bottom portion 12, and has a linear end edge on the insertion port portion 11 side, and has an arc-shaped end edge on the bottom portion 12 side. The other side end portion 14 extends from the insertion port portion 11 toward the bottom portion 12 and is disposed on the side facing the one side end portion 13, and the edges of the two synthetic resin films 1 a and 1 b overlap to be continuous. And formed by welding. The other side end portion 14 has a linear edge throughout.

  Two open / close rows 120 a and 120 b are formed on the bottom 12. Each of the open / close rows 120a and 120b includes a group of a plurality of aperture portions 121 and a aperture portion 122. One aperture portion 121 and one aperture portion 122 are formed alternately in the direction in which the edge of the bottom portion 12 extends. Each of the open / close rows 120 a and 120 b is disposed along the edge of the bottom portion 12. In the two rows of opening / closing rows 120a and 120b, one opening portion 121 and one closing portion 122 are arranged at different positions in the direction from the bottom portion 12 toward the insertion port portion 11. That is, the group of the plurality of open hole portions 121 and closed hole portions 122 includes not only the direction in which the edge of the bottom portion 12 extends but also the direction intersecting the direction in which the edge of the bottom portion 12 extends (orthogonal direction), that is, the bottom portion 12 and Also in the direction connecting the insertion port portion 11, the one hole portion 121 and the one hole portion 122 are arranged in a staggered manner and at different positions.

  As shown in FIG. 2, in the opening portion 121, a part of the two synthetic resin films 1 a and 1 b is overlapped and not welded, so that a space through which gas can pass is formed. The opening portion 121 formed at the edge on the bottom 12 side has an opening 123 that communicates with the outside of the bag. On the other hand, the closed hole portion 122 forms a side wall that stops the passage of gas because a part of the two synthetic resin films 1a and 1b are overlapped and welded. On the insertion opening 11 side of the closed hole portion 122, a part of the two synthetic resin films 1a and 1b are overlapped and not welded, so that a space for storing bananas, that is, a bag interior 10 is formed. ing.

  As shown in FIG. 3, on the insertion port 11 side of the closed hole portion 122, a part of the two synthetic resin films 1 a and 1 b are not overlapped and welded, so adjacent to the open hole portion 121, A space for storing bananas, that is, a bag interior 10 is formed.

  As shown in FIG. 4, the gas generated in the bag passes through the opening 123 formed at the edge of the bottom portion 12 through the opening 121 sandwiched between the two closing portions 122, as indicated by an arrow G. Discharged outside. At this time, the closed hole portion 122 acts to stop the passage of gas.

  In addition, although the length and space | interval of the opening part 121 and the closing part 122 are about 16 mm, for example, it is not limited to this length and space | interval, It changes suitably according to the magnitude | size of a stored item or a bag. be able to. Moreover, the number of the open / close rows formed is not limited to two, and can be appropriately changed according to the size of the stored items or bags.

  Using the banana packaging bag 1 configured as described above, the banana 100 is accommodated in the banana packaging bag 1 from the insertion opening 11 as shown in FIG. Then, as shown in FIG. 6, the insertion port part 11 is sealed using the seal | sticker 200 with a back sealer. In this state, the banana 100 is displayed at a store or the like. At this time, when a gas such as ethylene gas is generated in the bag from the banana 100 as the stored item, since the bag is in a sealed space, the bag swells and the internal pressure of the bag increases. With this pressure, ethylene gas is discharged out of the bag through a plurality of apertures 121 as shown in FIG. For this reason, the freshness and quality of the banana 100 can be maintained without being adversely affected by the gas generated by the banana 100. For example, it is possible to prevent the banana 100 from becoming black and to hold the banana 100 in an attractive manner.

  Further, it is possible to prevent outside air such as air from entering the bag through the plurality of hole portions 121 due to the pressure of the gas generated inside the bag. For this reason, since oxygen gas does not enter the bag, the banana 100 can be prevented from being oxidized. Thereby, the taste and freshness can be maintained without the banana 100 rotting.

  Further, while the gas is generated from the banana 100, the internal pressure is higher than the external pressure, but when the gas is not generated, the internal pressure and the external pressure are in an equilibrium state. Also at this time, since the gas does not enter and exit through the plurality of opening portions 121, it is possible to prevent outside air such as air from entering the inside of the bag through the plurality of opening portions 121.

  In particular, in the banana packaging bag 1 of the present invention, the open / close rows 120a and 120b made up of a group of the plurality of hole portions 121 and the hole portions 122 are positioned on the bottom portion 12 of the bag. When the banana 100 having the expanded portion of the tuft 110 is stored, the expanded portion can be positioned at the bottom 12 of the bag. For this reason, it becomes easy to quickly discharge the ethylene gas generated from the bunch 110 of the banana 100 out of the bag through the plurality of opening portions 121.

  In the two open / close rows 120a and 120b, one opening portion 121 and one closing portion 122 are arranged in different positions in the direction from the bottom portion 12 toward the insertion port portion 11, so that oxygen gas, etc. In addition to preventing the outside air from entering the bag, it is possible to effectively prevent insects from entering the bag.

  Instead of the banana packaging bag 1 of the present invention, as shown in FIG. 7, a banana packaging bag 2 having a large number of fine holes (not shown) is used to store bananas in the same manner as described above. To do. In this case, oxygen gas hardly enters the inside of the banana packaging bag 2 from the outside of the banana packaging bag 2 through a large number of fine holes, so that deterioration in quality due to banana oxidation can be suppressed. Insects can be prevented from entering the inside of 2. However, ethylene gas generated from the banana tends to accumulate inside the banana packaging bag 2. For this reason, when the banana packaging bag 2 is used, the surface area where the banana becomes black becomes larger and the appearance becomes worse than when the banana packaging bag 1 of the present invention is used.

  Moreover, as shown in FIG. 8, using the banana packaging bag 3 formed by arranging six holes 31 having an opening diameter of about 6 to 10 mm with an interval corresponding to the length of the banana, Store bananas in the same way. In this case, ethylene gas generated from the banana can be discharged from the six holes 31. However, since oxygen gas enters the inside of the banana packaging bag 3 from the outside of the banana packaging bag 3 through the hole 31, the banana is oxidized and the quality deteriorates.

  In the above embodiment, the example in which the banana is stored using the packaging bag of the present invention has been described. However, as shown in FIG. 9, the broccoli 300 having the bunch 310 is formed using the broccoli packaging bag 4. Even if it is housed, the same effects as described above can be achieved. In this case, each of the one-side end portion 13 and the other-side end portion 14 may be formed so as to bend toward the bottom portion 12. The packaging bag of the present invention is not limited to bananas and broccoli as stored items, and can be applied when storing various fruits and vegetables that can generate gas.

  It should be considered that the embodiments disclosed herein are illustrative and non-restrictive in every respect. The scope of the present invention is shown not by the above embodiments but by the scope of the claims, and is intended to include all modifications and variations within the meaning and scope equivalent to the scope of the claims.
