Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a double bag for fruits used during cultivation of fruits.

[0002]

[Prior art]

 Conventionally, double bags used for growing apples are generally made of an outer bag with high light-shielding properties and an inner bag with low light-shielding properties. In the cultivation of apples, when the child is young, the apples are covered with the above-mentioned double bag, the chlorophyll of the apple epidermis is removed, and the outer bag is removed before the harvesting period is reached to allow sunlight to reach inside. The bag is exposed to the surface of the fruit through a bag, and after gradually adjusting to the sun's rays, the inner bag is removed, further encouraging apple coloring and preventing sunburn.

[0003] In this double-bagged cultivation with bags, it is necessary to carry out bag removal twice as described above. In particular, since the suitable period of bag removal work is short, the bag removal work is carried out twice during that time. And labor shortages and aging populations are putting a heavy burden on farmers.

[0004] However, as a result of recent experiments and research by the inventors, guidance to farmers, and trial and error by the farmers themselves, the weather, time, and fruits of the bag removal day were replaced with twice removal of bags. If the degree of maturity is comprehensively considered, double bags can be removed at one time, and such a one-time bag removal technique is becoming more and more popular. It is not impossible to remove the bags at once, even with the conventional double bags for removing bags twice, but there is an increasing demand for a double bag that is more workable and is exclusively used for removing bags once.

[0005] The inventors of the present invention put the inner bag, which is formed by overlapping both edges of the sheet member first, into a bottomed outer bag, and put the overlapped portion of the inner bag on the front side of the outer bag. And a notch was provided from the upper edge of the inner bag along one side edge of the sheet body of the overlapped portion, and this was provided from the upper edge of the outer bag. Providing a part that can be inserted into the fruit stalk so that it can be inserted easily so that the stalk can be easily protected, and the bag can be removed at once. did.

[0006]

[Problems to be solved by the invention]

 In the above-mentioned proposal, the bag can be easily attached to the stem or the like, and the inner bag contained in the outer bag may have a cylindrical shape by overlapping both edges of the sheet body. Thus, it is possible to remove the inner bag together with the outer bag at once, but it is intended to provide a device that can easily do this.

[0007]

[Means for Solving the Problems]

 According to the present invention, the inner bag to be placed in the outer bag having the bottom is formed into a substantially cylindrical shape by overlapping both edges of the sheet body, and the overlapping portion of the inner bag is formed in the width direction on the surface side of the outer bag. The outer bag and the inner bag are fixed so that they are located in the center of the outer bag. Or a discontinuous cutting line extending in the vertical direction from the front side of the outer bag to the upper end on the back side via the bottom thereof in close proximity to the lower end of the inner bag corresponding to the discontinuous cutting line. An upwardly extending cut line or cut line of appropriate length should be formed.

[0008] The stem can be easily inserted into the insertion portion, so that the bag can be easily covered, the fruit can be sufficiently protected, and both sides of the bottom of the outer bag can be picked and pulled left and right. In addition, the discontinuous cutting line provided in the outer bag is cut open from the bottom toward the front side and the upper part on the back side, and the overlapping part is opened on the front side of the inner bag, and upward from the lower end part on the back side. Since the sheet is opened by being guided by the extended cutting line or the discontinuous cutting line, the bag can be easily removed at once.

[0009]

Embodiment

 Hereinafter, the present invention will be described with reference to the drawings. The outer bag 1 made of paper is formed with a bottom having an open upper part. In the illustration, both corners 12, 12 of the bottom 11 are cut so that rainwater or the like can be drained. An insertion portion 14 for inserting a fruit stalk, a branch, or the like is formed substantially at the center of the front side 13 of the outer bag 1. In the illustrated embodiment, a cutout portion 16 is formed substantially at the center in the horizontal direction of the upper edge portion 15, and a cutout portion 17 having a required length is provided in the vertical direction following the cutout portion 16. . The notch 16 can be formed in a U-shape, a V-shape, or any other appropriate shape in addition to the arc shape shown.

The inner bag 2 is a sheet made of paper such as paraffin paper having an appropriate color, and is formed into a cylindrical shape large enough to be able to be housed in the outer bag 1 by overlapping both edges 21 and 22 thereof. The overlapping portion 23 is located substantially at the center in the lateral direction on the front side 13 of the outer bag 1. In the illustrated outer bag, the width: length is about 13.5 cm: 17 cm. In a bag of such a size, the width of the overlapping portion 23 of the inner bag 2 is about 10 to 20 mm, preferably about 10 to 20 mm. It is preferable that the overlapped portion is made relatively large by setting it to about 15 mm. If the size of the outer bag changes, the size of the overlap should be changed according to the above.

In the inner bag 2, the upper portion of the overlapping portion 23 is fixed in a tubular shape by an adhesive portion 24 having a dot shape or a line shape to prevent displacement. An insertion portion 26 is formed substantially at the center of the front side 25 of the inner bag 2, and can cooperate with the insertion portion 14 of the outer bag 1 to insert fruit stems, branches, and the like when the bag is covered. Like that.

In the illustrated embodiment, a cutout portion 28 of an appropriate length is provided from the rim portion 27 of the inner bag along one of the edges 21 and 22 located in the overlapping portion 23. A butting portion 29 is formed such that both edges thereof abut. In the figure, a cutout portion 28 is provided along the left side edge portion 21, and a protruding portion 30 corresponding to the cutout portion 28 protrudes from below. The projections can be cut off. The inner bag 2 and the outer bag 1 are arranged in a positional relationship such that they are adjacent to each other such that the butted portion 29 of the inner bag 2 overlaps or is near the cutout portion 17 provided in the outer bag 1. Thus, the insertion portions 14 and 26 are formed.

The outer bag 1 has a discontinuous cut line such as a perforation extending vertically from the front side 13 to the rim 15 of the back side 18 via the bottom 11 so as to be continuous with the insertion portion 14. 19 is provided to facilitate bag removal by separating the discontinuous cutting line. The discontinuous cut line may be formed so as to be close to the insertion portion 14, extend from the front side 13 to the rim 15 of the rear side 18 via the bottom 11.

On the front side 13 and the back side 18 of the bottom portion 11 of the outer bag 1, if the cut line portion 41 of the discontinuous cut line 19 is formed to be longer than other portions, the operation for removing the bag is further facilitated. become. A stopper 3 is provided on an upper portion of one side of the outer bag 1 and is positioned so as to be sandwiched by a bonding portion 20 for forming the outer bag in the illustrated case.

The inner bag 2 is provided with a cutting line 32 or a discontinuous cutting line of an appropriate length extending upward from the central portion of the lower end of the rear side 31 so as to correspond to the discontinuous cutting line 19 of the outer bag 1. ing. In the illustrated inner bag 2, the lip 27 is arranged to be shifted downward so that the lip 27 is located below the lip 15 of the outer bag 1. A projection 33 for hooking protruding upward from the portion 27 is provided, and a concave portion 34 corresponding to the convex portion 33 is provided on the lower edge portion. The cutting line 32 extends upward from the concave portion 34. ing. The convex portion 33 of the inner bag 2 may be fixed to the rear surface 18 of the outer bag 1 with an adhesive such as glue.

Further, it is more preferable that the outer surface of the inner bag 2 is bonded to the inner surface of the outer bag 1 with point-like or linear bonding portions 35 and 36 in the upper portion near the insertion portion 26. Further, in the illustrated example, the inner bag 2 is adhered to the rear side 18 of the outer bag 1 with the adhesive portions 37 and 38 sandwiching the discontinuous cut line 19, thereby making it easier to remove the bag once. .

When using this, when the mouth of the double bag 4 is opened, the upper portion of the overlapping portion 23 of the inner bag 2 is bonded 24 so that the upper portion of the double bag 4 is hooked on the inner bag or the upper portion of the inner bag is Fruits such as apples can be securely stored in the inner bag without being bent. Then, the stem portion of the fruit can be simultaneously inserted into the insertion portions 14 and 26 formed by the butting portion 29 of the inner bag and the cutout portion 17 of the outer bag. Try to close the parts together. Then, if the clasp 3 is bent or the mouth is closed, the fruit can be easily bagged.

In such a bag-covered state, even if fruits grow or the inner bag 2 is subjected to a force due to wind or the like, the inner bag has a cylindrical shape having the overlapping portion 23 as described above. Since the inner bag is fixed to the outer bag, the inner bag is not displaced so as not to impair the covered state, and the overlapping portion 23 can be expanded so as to conform to the enlargement of the fruit, The fruit can be reliably covered.

At the time of bag removal, if the lower side of the outer bag 1 is pinched and expanded to the left and right, the discontinuous cut line 19 is cut from the cut line portion 41 of the bottom 11 and the outer bag is torn on both sides. Sometimes, the overlapping portion 23 is opened on the front side of the inner bag, and the cutting line 32 or the discontinuous cutting line extending from the lower end guides the opening on the rear side, so that the outer bag and the inner bag are separated. Both bags can be easily opened by opening both sides. Further, at this time, since the insertion portion 26 of the inner bag also forms the butted portion 29 by the cutout portion 28, the inner bag can be removed cleanly without leaving a part of the inner bag in the stalk.

In the case where the upper edge of the inner bag is located below the upper edge of the outer bag, the upper portion of the double bag is only the outer bag. There is little resistance when the part is squeezed to close, and the bag can be easily covered with a light operation to improve the work efficiency. The convex part 33 is provided at the upper part of the inner bag and the corresponding concave part 34 is provided at the lower part. In this case, the amount of paper for forming the inner bag can be reduced, and the cost can be reduced.

[0021]

[Effect of the invention]

 As described above, the present invention makes it possible to easily carry out bagging work on fruits, and to protect fruits from pests, wind, rain, sunlight, etc. with a double bag, and obtain high quality fruits. Simply pulling the bag on both sides of the bottom of the outer bag to the left and right to tear it also allows the inner bag to be similarly torn and be removed all at once, thereby improving work efficiency and improving the overall efficiency. Productivity can be greatly improved.
