Description

  The present invention relates to an irregular fruit packaging bag, and more particularly to an irregular fruit packaging bag that is optimal as a packaging bag for selling bunch bananas.

  As a packaging material for displaying a bunch of bananas at a store and offering them for sale, as shown in FIG. 6, an OPP film having a heat-sealing property is used to form a bag having an outer shape that conforms to the shape of the bunch of bananas. .

In banana retail sales, the banana skin is packaged in a completely ripe state.
When the ripening further proceeds with ethylene gas, the meat quality is softened and the commercial value is lowered. Therefore, a large number of holes b are formed in the bag a in order to escape the generated ethylene gas.

  However, such a perforated bag is not preferable because there is a possibility that insects may enter from the hole b. Further, the conventional film bag cannot be expected to have a buffer function at all, so that it is easy to damage the banana by rubbing against each other during handling or display after packaging.

  There are no documents showing means for solving the above problems.

  The present invention is able to wrap bunch bananas and similar irregular fruits such as bunch grapes, bunch petit tomatoes, etc. without losing their form, and can maintain the breathability after packaging. It is an object of the present invention to provide an unshaped fruit packaging bag which does not intrude and does not damage the fruits even when rubbed after packaging, and which can give a high-class feeling and enhance the display effect.

  As a means for solving the above problems, the present invention is a bag having one end opened, wherein one half of the bag from the opening to the bottom is made of a transparent resin film and the other half is made of a nonwoven fabric. The nonwoven fabric portion is folded inward along the longitudinal direction to form a gusset portion, and the lower end of the resin film and the nonwoven fabric gusset portion are sealed together to form the bottom portion of the bag.

  A second aspect of the present invention is that the folding width of the gusset portion of the nonwoven fabric is set to be substantially the same width as the nonwoven fabric portion serving as the outer surface. According to this, it is preferable when increasing the adaptability to the shape of the irregular-shaped fruit to be packaged.

  A third aspect of the present invention is that the transparent resin film is an OPP film having a good sealing property.

  According to a fourth aspect of the present invention, one side edge of the left and right nonwoven fabrics is heat-sealed to the left and right side edges of the transparent resin film having a band shape, and the other side edges of the left and right nonwoven fabrics are folded outward to fold the left and right sides. The base portions of the portions are heat sealed, the left and right nonwoven fabrics are folded in the longitudinal direction to form a gusset portion, and the bag bottom is formed by heat fusing at a predetermined bag length position.

  According to a fifth aspect of the present invention, when the irregular fruit is a bunch banana, the gusset portion of the non-woven fabric bulges outward when the bunch banana has the tip of the transparent resin film as the bottom side and the back side of the bunch banana warp as the non-woven side. The outer edge of the bottom part of the gusset part is pulled up and the nonwoven fabric is fitted and stored so as to fit in the shape of a bunch banana.

  According to the present invention, one half of the bag is composed of a nonwoven fabric, only the other half is composed of a transparent resin film, and the nonwoven fabric portion is folded inward along the vertical direction of the bag to form a gusset portion. Therefore, even if the irregular fruit is a bunch of bananas, if the tip of the bunch of bananas is inserted as the bottom side of the transparent film, the back side of the bunch of bananas bulges the gusset of the nonwoven fabric outward. It is possible to accept an irregular shaped bunch of bananas without hindrance, and at the same time, the bottom end of the nonwoven fabric is pulled upward by this bulging of the gusset, so that the nonwoven fabric fits in the shape of a bunch of bananas and is in a stable state Can be stored.

  In particular, the nonwoven fabric has a gusset portion, so that it conforms well to the size and shape of the tufted banana, and can be made into a packaging bag that can be easily packaged even if it is a tufted banana.

  Further, since the nonwoven fabric has air permeability, there is no need to make a hole for exhausting ethylene gas in the bag, and therefore there is no possibility of invasion of insects, and safety can be improved.

  Furthermore, since the non-woven fabric part fits well into the bunches of bananas, the display effect is improved, and at the same time, a high-class feeling can be created, and the interior can be seen through through a transparent resin film at the time of display. Will not be disturbed.

  In addition, even if the ones packaged after packaging are rubbed together, the banana is prevented from being damaged because the nonwoven fabric has a buffering property.

  The effects described above can be obtained in the same manner even for irregular fruits such as bunch grapes other than bunch bananas, bunch cherry tomatoes, and the like.

  If a packaging bag is comprised like Claim 4, it can be manufactured with the existing bag making machine, can be provided cheaply, and yet the seal part (folding part) of the other side edge of a nonwoven fabric Is located on the outer surface side of the bag, the sealing part does not come into contact with the irregular shaped fruits even if the non-woven fabrics are sealed, and the fruits are not adversely affected.

  FIG. 1 shows a perspective view of an embodiment of an irregular fruit packaging bag 1 according to the present invention, and FIG. 2 shows a schematic cross section taken along the line AA of FIG.

  One end of the packaging bag 1 is open, one half of the direction from the opening 1 a to the bottom 1 b of the other end is made of the transparent resin film 2, and the other half is made of the nonwoven fabric 3.

  The nonwoven fabric 3 is formed into a gusset portion 4 by being folded inward along the longitudinal direction at one side edge of the packaging bag 1, and the nonwoven fabric 3 in which the gusset portion 4 is overlapped from the transparent resin film 2. Both are fixed to the lower end by the heat seal 5, thereby forming the bottom 1b.

  The folding width L of the gusset portion 4 is substantially the same width as the non-woven fabric portion serving as the outer surface. The transparent resin film 2 is an OPP film in consideration of heat sealing properties. The film 2 is not limited to the OPP film, and may be another resin film. However, the transparency is preferably a colorless transparent film. However, in some cases, it may be a light colored film.

  As the structure of the packaging bag 1, as shown in FIGS. 5 (A) to (D), the width of the film 2 is substantially the same as the width of the left and right side edges of the strip-shaped transparent resin film 2 having the required width. The respective one side edges of the left and right strip-shaped nonwoven fabrics 3 and 3 are joined by the heat seals 6 and 6, respectively (FIG. 5A), and the other side edges of the left and right nonwoven fabrics 3 and 3 are outward. The folded portions 3a and 3a are folded, the base portions are joined together by a heat seal 7 and joined (FIG. 5B), and then the transparent resin film 2 is folded in half at the longitudinal center (FIG. 5). (C)) After that, the heat seal 7 portion of the nonwoven fabric 3, 3 is folded inward to form the gusset portion 4 (FIG. 5 (D)), and the bottom portion 1b is formed by heat fusing at a predetermined bag length position. The packaging bag 1 is obtained by forming and opening 1a.

  If said structure is employ | adopted, it can be bag-made using the existing bag making machine, and the packaging bag 1 can be obtained cheaply, without requiring special special machinery equipment.

  3 and 4 exemplify the case where the bunch banana 8 is packaged as an irregular shape fruit in the packaging bag 1, and the tip 8a of the bunch banana 8 is transparent resin film as shown in FIG. The back portion 8b of the bunch banana 8 is inserted into the packaging bag 1 as the non-woven fabric 3 side with the bottom portion 1b side of the two portions.

  Then, the gusset portion 4 of the nonwoven fabric 3 is expanded from the inside by the swelling of the back side 8b of the bunch banana 8, and expands following the shape of the back side 8b of the bunch banana 8, and the outside of the bottom 1b on the non-woven fabric 3 side is expanded at this time. Since the end 1 c is pulled upward as seen in FIG. 3, the nonwoven fabric 3 fits comfortably over most of the back side 8 b of the bunch banana 8 so as to wrap the bunch banana 8, and the opening 1 a is closed with the stopper 9. Complete the packaging.

  By packaging in this way, the surface opposite to the back side 8b of the bunch banana 8 is located in the transparent resin film 2 so that the buyer can clearly see the color gloss of the bunch banana 8 from the outside (see FIG. 4). State), it can be displayed at the store as a form that does not hinder product definition, and at the same time, a high-class feeling can be brought out at the time of display.

  Further, as described above, the gusset portion 4 of the nonwoven fabric 3 bulges outward and comes into close contact with the shape of the back side 8b of the bunch banana 8. Since the raised portions 3a and 3a are located on the outer surface side, they do not come into contact with the bunch banana 8, and the bunch banana 8 is not damaged by the folded portions 3a and 3a.

  When packaged in this way and displayed at the storefront, even if the packages are rubbed together, the bunch banana 8 is prevented from being damaged by the buffering function of the nonwoven fabric 3.

  Even if ethylene gas is generated during the display, it is released to the outside through the breathable nonwoven fabric 3, and the quality of the bunch banana 8 is not deteriorated.

  As described above, the case of the bunch banana 8 is shown as the irregular fruit. However, the bunch of irregular fruit, for example, the bunch grape, the tufted cherry tomato, etc., can be similarly packaged for sale.
