By providing the inner bag so that it can be stretched, and stacking both ends of a sheet body having a substantially rectangular outer bag, and applying and bonding an adhesive along the longitudinal direction of the overlapping portion and the lower edge of the outer bag It proposes a fruit hanging bag which has a bottomed shape with an opening at the upper edge and a blank portion where no adhesive is applied to the upper portion of the overlapping portion.

Japanese Patent No. 2829945

  The fruit hanging bag prevents the formation of chlorophyll which hinders the subsequent vivid coloring because the outer bag blocks sunlight in the fruit fruit stage, and removes the outer bag at the stage of maturity (unbag removal) ), Which promotes the coloring of the fruit in a state where only the translucent inner bag is hung on the fruit. By the way, the fruit contained in the fruit hanging bag is enlarged as it goes from the juvenile stage to the maturity stage. In the fruit hanging bag, vertical folds are formed on both sides of the inner bag, and the overlapping part of the outer bag is formed. By forming a blank area where no adhesive is applied on the top of the bag, the vertical folds of the inner bag and the blank area of the outer bag are pushed outward by the expansion pressure due to fruit enlargement, and the inner bag and the outer bag are opened. When the outer bag that covers the fruit becomes larger, the outer bag is not stretched along the outer periphery of the fruit, and the outer bag is easy to be removed. Can maintain a state where the overlapping portion as the paste margin of the outer bag is also overlapped, so that it is possible to wipe out defective coloring of fruits due to incidence of sunlight.

  However, due to changes in cultivation methods due to recent fruit varieties improvement and consumer preference for large varieties, and differences in weather from year to year, depending on the fruit varieties and individual differences, the bottom edge of the margin ( The upper end of the bonded part) may be located above the maximum enlarged part of the fruit. In this way, when the lower end of the blank portion is positioned above the maximum enlarged portion of the fruit, the expansion pressure accompanying the growth of the fruit is applied to the adhesive portion, and the expansion pressure of the fruit is not applied to the blank portion. Therefore, it may happen that the outer bag is closely attached to the fruit in a stretched state so as to wrap the fruit, and the blank portion for spreading the outer bag outward does not function. In this case, since the inner edge of the outer bag is stretched along the fruit when the outer bag is removed, the outer bag cannot be effectively removed. That is, as described above, the purpose of providing a blank portion in Patent Document 1 is to pull out the outer bag with one hand by expanding the overlapping portion of the blank portion outward by the expansion pressure accompanying the growth of the fruit. If the lower end of the margin is positioned above the maximum enlarged part of the fruit, the outer bag will not spread by the margin, so hold the fruit with one hand. The other hand is forced to perform an extremely inefficient work such as holding the upper part of the outer bag and repeating the tearing several times.

  Such a problem may occur when the lower end of the margin part is located above the maximum enlarged portion of the fruit. For example, the lower end of the margin part may be lowered to increase the length of the margin part. However, if the lower end of the margin part is lowered in this way, the length of the adhesive part will be shortened accordingly, and in the fruit stage of the fruit, the margin part will be curled or the margin part will be separated, etc. There is a concern that sunlight enters from the gap and chlorophyll is formed, which hinders vivid coloring during the harvest period.

  The present invention has been made in order to solve the above-described problems, and the margin is shortened as much as possible in the fruit fruit stage, and the margin part is accompanied by fruit enlargement in the fruit maturation period. It aims at providing the fruit hanging bag which can extend the length of.

  The invention of claim 1 for achieving the above object is to form a double-structured fruit hanging bag integrated with an outer bag and an inner bag, and the outer bag has an overlapping portion at one end of a substantially rectangular sheet body. Fold the sheet body in half so that it remains, fold the overlap part over the other end of the sheet body, and apply adhesive along the vertical direction of the overlap part and the lower edge of the outer bag To form a bag with a bottom and an opening only at the upper edge, and to form a blank portion where no adhesive is applied to the upper portion of the overlapping portion. It is composed of a strong adhesion area and an upper weak adhesion area adjacent to the margin part, and the weak adhesion area can be peeled off by expansion pressure due to the growth of fruits contained in the inner bag.

  The invention according to claim 2 is characterized in that a composition ratio of the margin part to the adhesive part is set to 1: 1.5 to 1: 3.

  The invention of claim 3 is characterized in that the composition ratio of the weakly bonded area and the strongly bonded area in the bonded portion is 1: 1 to 1: 5.

  The invention according to claim 4 is characterized in that the weakly bonded region is composed of a non-bonded portion and a spotted bonded portion.

  The invention according to claim 5 is characterized in that the weakly bonded area is formed so that the adhesive application area is narrower than that of the strongly bonded area.

  The fruit hanging bag according to the invention of claim 1 is a bag shape whose inner bag can contain the fruit fruit, so that the fruit can be covered with the fruit at the fruit stage to prevent disease, insect control and growth of the fruit. The effect of promoting, preventing the damage | wound of the surface of a fruit, etc. can be exhibited. The outer bag has a blank portion where no adhesive is applied, a strong adhesion area, and a weak adhesion area. The weak adhesion area is formed adjacent to the blank portion. As a result, when the fruit grows and swells inside the inner bag, the blank portion where the adhesive is not applied opens due to the expansion pressure due to the growth of the fruit, and the maximum enlarged portion of the fruit contained in the outer bag is from the lower end of the blank portion. Even when it is in a lowered position, the outer bag's adhesive part is composed of a strong adhesive area and a weakly adhesive area, and the weak adhesive area is formed adjacent to the blank area, resulting in fruit growth. The weak adhesion region peels off due to the expansion pressure, and the peeled portion can be continuous with the blank portion to extend the region of the blank portion. Thereby, the inner edge of the outer bag is not stretched along the fruit, and the outer bag can be easily removed simply by pulling the outer bag with one hand. In addition, in the fruit fruit stage, since the overlapping part is closed by the weak adhesion area, the fruit is held by the outer bag without dripping in the blank part or opening the blank part and entering sunlight. Since it can be reliably shielded from light, the formation of chlorophyll, which hinders coloring, can be suppressed in the fruit growing stage.

  The fruit hanging bag according to the invention of claim 2 can optimize the composition ratio of the blank portion and the bonded portion according to the type of fruit grown in the fruit hanging bag.

  The fruit hanging bag of claim 3 can optimize the composition ratio of the weakly bonded area and the strongly bonded area in the bonded portion according to the kind of the fruit grown in the fruit hanging bag.

  The fruit hanging bag according to claim 4 comprises a non-adhesive part and a blank part by separating the spotted adhesive part by an expansion pressure due to the growth of the fruit by configuring the weakly adhesive area with the non-adhesive part and the spotted adhesive part. Since the margin of the outer bag spreads further outwards, the inner edge of the outer bag does not stretch along the fruit, and the outer bag can be easily removed simply by pulling the outer bag with one hand. Can be bagged. In addition, in the fruit fruit stage, since the overlapping part is closed by the weak adhesion area, the fruit is held by the outer bag without dripping in the blank part or opening the blank part and entering sunlight. Since it can be reliably shielded from light, the formation of chlorophyll, which hinders coloring, can be suppressed in the fruit growing stage.

  The fruit hanging bag of claim 5 is such that the weak adhesive area is weaker than the strong adhesive area by forming the weak adhesive area narrower than the strong adhesive area. As a result, the weak adhesion area with weak adhesive strength peels off due to the expansion pressure due to the growth of the fruit, and the area of the margin part expands continuously with the peeled part and the margin part, so that the inner edge of the outer bag stretches along the fruit However, the outer bag can be easily removed simply by pulling the outer bag with one hand. In addition, in the fruit fruit stage, since the overlapping part is closed by the weak adhesion area, the fruit is held by the outer bag without dripping in the blank part or opening the blank part and entering sunlight. Since it can be reliably shielded from light, the formation of chlorophyll, which hinders coloring, can be suppressed in the fruit growing stage.

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

  The fruit hanging bag 1 is formed by overlapping an inner bag 2 and an outer bag 3, and the upper side of the inner bag 2 is exposed above the outer bag 3. At the center of the upper edge of the inner bag 2, a V-shaped notch 4 for inserting a fruit tree branch B when the fruit A is hung is provided. Further, both side portions of the inner bag 2 are folded in a Z shape to form vertical pleats 5 on both side portions of the inner bag 2, and both ends of the inner bag 2 are overlapped to form a glue margin surface 6. The upper and lower edges of the inner bag 2 are opened by bonding the surface 6 with an adhesive. Thus, by forming the vertical pleats 5 folded in the Z shape on both sides of the inner bag 2 and pasting the adhesive marginal surface 6 that becomes the overlapping portion of the inner bag 2, the effective opening diameter of the inner bag 2 is reduced. 3 is substantially larger than the opening diameter of 3. Further, a thin wire 7 used for fixing the inner bag 2 is enclosed in the adhesive allowance surface 6 of the inner bag 2. Moreover, the adhesive piece 13 connected via the tear line 13a is formed in the lower end of the inner bag 2. As shown in FIG.

  The outer bag 3 is folded in half so that the overlapping portion 10 is left at one end of a substantially rectangular sheet body formed shorter than the inner bag 2, and the overlapping portion 10 is connected to the other end of the sheet body. The outer bag 3 is made into a bag shape having a bottom and opening only at the upper edge portion by folding the overlapping portion 10 and applying and bonding an adhesive to the lower edge portion 8 of the overlapping bag 10 and the outer bag 3. Bagged. In addition, the bottom edge both corners of the outer bag 3 form a drain opening 12 by forming a region where the lower adhesive portion 8a to which the adhesive is applied is not formed, and the drain opening 12 enters the outer bag 3 from the drain opening 12. Effective drainage of invading rainwater. Further, the adhesive piece 13 is bonded and fixed to the center of the bottom edge of the outer bag 3 by the lower-side adhesive portion 8 a that is sandwiched between the front and back paper of the outer bag 3 and the outer bag 3 is bonded. Further, as shown in FIG. 1, the adhesive portion 14 of the overlapping portion 10 at both ends of the outer bag 3 is formed at the lower portion in the vertical direction of the overlapping portion 10, and the upper portion of the overlapping portion 10 has a blank portion 15 to which no adhesive is applied. Form. In the present embodiment, since the drainage openings 12 are formed at both corners of the bottom edge of the outer bag 3, a slight margin 12a having no adhesive portion 14 is also formed at the lower end of the overlapping portion 10. However, it is not always necessary to form the blank portion 12 a at the lower end portion of the overlapping portion 10, and the adhesive portion 14 may be formed up to the lower end portion of the overlapping portion 10. Further, the blank portion 15 on the upper portion of the overlapping portion 10 is a portion that is expanded outward by the amount of the overlapping portion 10 by the pressure accompanying the volume expansion due to the growth of the fruit A stored in the fruit hanging bag 1. Moreover, the adhesion part 14 is comprised by the strong adhesion area | region 14a from which the lower part is hard to peel, and the weak adhesion area | region 14b located in the upper part of this strong adhesion area | region 14a. Moreover, as shown in FIG. 1, the upper end of the strong adhesion region 14a is formed so as to be positioned below the portion corresponding to the maximum diameter a of the fruit A.

  The bonding portion 14 is composed of a strong bonding area 14a and a weak bonding area 14b. The strong bonding area 14a is a portion where an adhesive is continuously applied with a certain width, and the weak bonding area 14b is The non-adhesive part 16 to which the adhesive is not applied and the dotted adhesive part 17 are configured. In this way, by forming the weak adhesion region 14b composed of the non-adhesion portion 16 and the dotted adhesion portion 17 on the upper portion of the strong adhesion region 14a, and forming the weak adhesion region 14b adjacent to the blank portion 15, Since the area of the dotted adhesion portion 17 is extremely small with respect to the continuously formed strong adhesion region 14a, the adhesive force of the weak adhesion region 14b is weaker than that of the strong adhesion region 14a. For this reason, when the expansion pressure due to the growth of the fruit A is applied to the dotted adhesion portion 17, the dotted adhesion portion 17 is peeled off by the expansion pressure of the fruit A. As described above, when the dotted adhesion portion 17 is peeled off by the expansion pressure of the fruit A, the non-adhesion portion 16 and the margin portion 15 are continuous, and a region spreading outward is also widened. By the way, although the upper end of the strong adhesion area 14a is formed so as to be located below the portion corresponding to the maximum diameter a of the fruit A, the maximum diameter a of the fruit A is the type of the fruit A, the environment for growing the fruit A, and the like. Therefore, the composition ratio between the blank portion 15 and the adhesion portion 14 and the composition ratio between the weak adhesion region 14b and the strong adhesion region 14a in the adhesion portion 14 are variously set within a predetermined range. That is, the configuration ratio of the blank portion 15 and the bonding portion 14 is set to 1: 1.5 to 1: 3, and the configuration ratio of the weak bonding area 14b and the strong bonding area 14a in the bonding section 14 is set to 1: 1 to 1. : Formed within the range of 5, as specific dimensions, the vertical width w of the outer bag 3 is 105 mm, the vertical width w1 of the entire bonded portion 14 is 50 mm to 70 mm, and the vertical width w2 of the margin 15 is 17 mm to The vertical width w3 of the weak adhesion region 14b is 8 mm to 35 mm, and the vertical width w4 of the strong adhesion region 14a is 25 mm to 58 mm. The inner bag 2 is formed of white or light-colored paraffin paper or water- and water-repellent paper, and has an appropriate translucency, while the outer bag 3 has an appropriate light-shielding property. ing. In addition, an adhesive portion 30 that partially adheres to the inner bag 2 and integrates the outer bag 3 and the inner bag 2 is formed on the upper surface of the front and back papers of the outer bag 3 by a tear line 31. 3 and separable.

  The usage method of the fruit hanging bag 1 of this invention comprised as mentioned above is demonstrated. As shown in FIG. 3, the fruit hanging bag 1 is put on the fruit A, the branch B is inserted into the notch 4 of the inner bag 2, the upper edge of the opening of the inner bag 2 is focused on the branch B, and the wire 7 The bag hanging work is completed by binding with the. Thus, by covering the fruit A with the fruit hanging bag 1, the prevention of diseases caused by rainwater and the progress of sugar content increase and maturity are promoted, and the inner bag 2 is hung until the harvesting period to cultivate the fruit A with diseases, pests, It can protect against contamination of pests and sprayed pesticides. In addition, the rainwater which accumulates in the outer bag 3 is drained to the outside from the drainage openings 12 provided at the lower ends on both sides of the outer bag 3.

  When a certain period of time has passed, the fruit A in the fruit hanging bag 1 grows and enlarges, and accordingly, the inner bag 2 expands in the radial direction as the vertical pleats 5 unfold. The outer bag 3 is shielded from light most of the period from the juvenile stage to the mature stage. At this time, since the lateral length of the outer bag 3 is shorter than that of the inner bag 2, the outer bag 3 is expanded from the inner side by the fruit A being grown by the enlargement of the fruit A. At this time, in the outer bag 3, the lower portion of the outer bag 3 in which the bonding portion 14 is formed remains in the bonded state, but the unbonded blank portion 15 is the fruit A stored in the fruit hanging bag 1. Because it spreads outside by the pressure accompanying the volume expansion due to growth of the sheet and spreads outside while maintaining the overlapping state of the overlapping portion 10 of the sheet body that constitutes the outer bag 3, it spreads without incident sunlight. The diameter becomes larger. Furthermore, when the fruit A grows and enlarges, the pressure accompanying the volume expansion of the fruit A is applied to the weakly bonded region 14b composed of the non-bonded portion 16 and the pointed bonded portion 17 formed on the strong bonded portion 14a. The weak adhesion area 14b having a lower adhesive strength than the strong adhesion area 14a is peeled off by the pressure of the fruit A. Thereby, since the non-adhesion part 16 and the margin part 15 continue, and the spreading allowance of the outer bag 3 increases, the inner edge of the outer bag 3 is not stretched along the fruit, and the outer bag 3 is removed. When doing so, the adhesive bag 13 is separated from the tear line 13 and the adhesive piece 13 is partially separated from the tear line 13a while the adhesive bag 30 that partially bonds the outer bag 3 and the inner bag 2 only by pulling the outer bag 3 downward. Only the outer bag 3 can be simply unpacked while the fruit A is wrapped in the inner bag 2. In this way, by removing the outer bag 3, it is possible to promote the coloring or the like of the fruit A.

  On the other hand, since the overlapping part 10 of the outer bag 3 is pasted together by the dotted adhesion part 17 during the period from the juvenile stage to the maturation stage of the fruit A, the blank part 15 can be formed as short as possible. Therefore, it is possible to reliably shield the sunlight that enters the outer bag 3 by, for example, the margin 15 being blurred or the margin 15 being opened by the influence of wind or the like.

  As described above, the blank portion 15 where the adhesive is not applied is formed at the upper end portion of the overlapping portion 10 for bonding the outer bag 3 with the adhesive, and the non-adhesive portion 16 is adjacent to the blank portion 15. By forming a weakly bonded area 14b that is easy to peel off with the pointed bonding part 17 and forming the upper end of the strong bonded area 14a below the part corresponding to the maximum diameter a of the fruit A, the fruit Due to the expansion pressure due to the growth of A, the spotted bonded portion 17 of the weakly bonded region 14b is peeled off, and the non-bonded portion 16 and the blank portion 15 can be continuously extended to extend the region of the blank portion 15. Thereby, the inner edge of the outer bag 3 is not stretched along the fruit, and the outer bag 3 can be easily removed simply by pulling the outer bag 3 with one hand. Moreover, in the fruit fruit stage, since the overlapped portion 10 is bonded by the weakly bonded region 14b, the marginal portion 15 is not bent and the marginal portion 15 is opened and sunlight is not incident. The fruit can be reliably shielded from light by the bag 3, and the formation of chlorophyll, which hinders coloring, can be suppressed in the growing stage of the fruit A.

  In addition, since the blank portion 15 can be formed by not providing an adhesive on the overlapping portion 10, it can be easily formed, and the weakly bonded region 14b also has a strong bonded region 14a and a non-adhered portion 16 that does not apply an adhesive. Since only the pointed adhesive portion 17 is formed at a distance, it can be formed easily.

  As mentioned above, although the Example of this invention was explained in full detail, this invention is not limited to the said Example, A various deformation | transformation implementation is possible within the range of the summary of this invention. For example, in the above-described embodiment, an example in which each of the non-bonding portion 16 and the pointed bonding portion 17 is formed is shown. However, as in the second embodiment of the present invention shown in FIG. The non-adhesive portions 16 and the dotted adhesive portions 17 may be arranged alternately. Furthermore, as in Example 3 of the present invention shown in FIG. 6, for example, the weak adhesion region 14b is constituted by a narrow portion 21 narrower than the strong adhesion region 14a, and the area of the weak adhesion region 14b is narrower than that of the strong adhesion region 14a. The structure which weakens the adhesive force of the weak adhesion area | region 14b rather than the strong adhesion area | region 14a by forming may be sufficient. Alternatively, adhesives having different adhesive strengths may be applied, the strong adhesive region 14a may be formed with an adhesive having a strong adhesive force, and the weak adhesive region 14b may be formed with an adhesive having a weak adhesive force. What is necessary is just to make it the structure in which the weak adhesive region 14b is easy to peel by the pressure accompanying the volume expansion of the fruit A by forming the weak adhesive region 14b whose adhesive force is weaker than the strong adhesive region 14a in the upper part of the adhesive part 14 which continues the part 15. .
