Description

  The present invention relates to a fruit bag used for fruits such as peaches, apples and plums, and more particularly to a fruit bag suitable for use with citrus fruits.

Conventionally, in fruit tree cultivation, in order to protect fruits from disease, insect damage, wind and rain, spraying agents, and the like, fruits are covered with a single fruit bag or multiple fruit bags in which a plurality of fruit bags are stacked. Among them, peaches, apples, citrus fruits, etc. are bound on the branches or bound between the fruit shafts, so I-shaped cut lines called mouth-cuts are placed in the opening of the fruit bags, or V-shaped It is used by making it easy to widen the opening by cutting it out. For example, the applicant of the present application has applied for a fruit double bag having a mouth cut portion at the opening in Patent Document 1.
Hereinafter, in the present specification, the I-type cut line, the V-type cut-out, and the like will be collectively referred to as a cut-in portion. Moreover, in this specification, when it only calls a "fruit bag", it means the multiple fruit bag which piled up the single fruit bag or the several fruit bag.

  The fruit bag is usually placed in the juvenile stage, but for citrus fruits, the purpose is to prevent frost and cold damage in winter, and it is common to carry out bagging after the fruit has grown sufficiently. In such bagging for citrus fruits, when the producer puts the bag, when the I-shaped cut line 103 is sandwiched between the fruit axes, the opening 101 needs to be opened widely. For example, as shown in FIG. 11, when a fruit bag 100 having a cut line 103 continuous from the notch 102 is hung on the fruit, as shown in FIG. 12, the opening 101 is opened and the fruit A is placed inside the fruit bag 100. When both sides of the opening 101 and the cut line 103 are opened too much, or when a fruit shaft or a branch is sandwiched between the cut lines 103, when trying to bind fruit bags without gaps, etc. Further, a tear 105 occurs in the fruit bag 100 from the end portion 103 ′ below the cut line 103, and there is a problem that it can no longer be used as a fruit bag. In FIG. 11, reference numeral 104 denotes a stopper for folding and winding the upper end portion of the opening 101 around the fruit shaft or branch passed through the cut line 103.

  In order to solve this problem, methods such as thickening or hardening the material (paper) of the fruit bag to make it difficult to tear are used. For the producers who perform the work, the material of the fruit bag is thick or hard, which increases the fatigue of the fingers, resulting in a problem that the efficiency of the bag hanging work is reduced.

  In view of the above problems, an object of the present invention is to provide a thin and soft fruit bag that is not easily torn during bag hanging.

  Hereinafter, specific embodiments of the present invention will be described with reference to the drawings. The following embodiment is one form when the present invention is embodied, and is not intended to limit the present invention within the scope thereof. In the description of the present invention, the vertical direction of the fruit bag is expressed as “upper” and “lower” in the state shown in the drawings. Thereby, the upper and lower sides of the fruit bag as a product are not specified.

  A first embodiment of the present invention will be described with reference to FIGS. 1 is a front view of a fruit bag in Example 1. FIG. The code | symbol 10 has pointed out the whole fruit bag. The code | symbol 11 is an opening part provided in the upper end part of the fruit bag 10 for introduce | transducing a fruit into the inside of a fruit bag. Reference numeral 12 denotes a cutout part formed by cutting out and processing the fruit bag side surface starting from the upper end of the opening 11 so that the operator can easily open the opening 11. The shape of the notch 12 is not limited to the shape shown in FIG. Reference numeral 13 denotes a cut line for making the opening 11 easy to open and for facilitating the pinching of the fruit axis or the branch. Reference numeral 14 denotes a clasp for folding the upper end portion of the opening 11 around the fruit shaft or branch passed through the cut line 13. An adhesive B as a reinforcing means for preventing tearing of the cut line 13 is applied to a terminal portion below the cut line 13 in a predetermined shape. The fruit bag 10 is formed into a bag shape by folding a sheet-like paper sheet and bonding it with an adhesive bonding part 15.

  FIG. 2 shows an initial state in which the fruit bag shown in FIG. 1 is hung on the fruit A (citrus fruit in this embodiment). A force F is applied to the fruit bag 10 whose opening 11 has been opened by the operator in a direction of pulling the opening 11 to both sides. In the conventional fruit bag, as described above, this force F concentrates on the end portion 13 ′ below the cut line 13 and becomes a tearing force, and the fruit bag tears further downward from the end portion 13 ′ of the cut line 13. However, the fruit bag 10 of the present embodiment can obtain a strength that can withstand the tearing force by the adhesive B as the reinforcing means. In addition, the adhesive B should just adhere to the side surface of the fruit bag 10 with its own adhesive force, and should have a fixed intensity | strength with respect to a tear, a plastics, an adhesive agent, an adhesive, or an adhesive surface or one side. A reinforcing tape or the like having an adhesive surface can be used. For the plastic, adhesive, and pressure-sensitive adhesive, a material that can be ignored at the time of completion of the product is selected (for example, by drying) even if the material is sticky at the time of application.

  Further, as shown in FIG. 3, in the next stage of the bagging operation, the end of the cut line 13 is crossed and the fruit axis is sandwiched. At this time, there was a risk of tearing downward from the score line 13 by crossing more than necessary due to excessive force applied to the operator, but it was torn by the end portion 13 ′ reinforced by the adhesive B. Can be prevented. Then, as shown in FIG. 4, the opening part 11 is closed using the clasp 14 so that the fruit bag 10 may not detach | leave from a fruit similarly to a normal fruit bag. In this way, tearing from the end portion 13 ′ below the cut line 13 of the fruit bag 10 can be prevented.

  Next, Example 2 will be described with reference to FIG. FIG. 5 shows the structure of a double fruit bag, (a) shows an inner bag, (b) shows an outer bag, and (c) shows a double fruit bag in which these are stacked. Reference numeral 20 denotes an inner bag of a double fruit bag. Similar to the fruit bag of the first embodiment, an opening 21, a notch 22, and a cut line 23 are formed. Reference numeral 30 denotes an outer bag. Similarly, the outer bag 30 has an opening 31, a notch 32, and a cut line 33, and a stopper 34 is further attached to the outer bag 30. The inner bag 20 is accommodated in the outer bag 30 to form a double fruit bag 40. The outer bag 30 is formed to be slightly larger than the inner bag 20 in terms of the dimensions of the openings 21 and 31 and other external shapes. FIG. 5C shows a double fruit bag 40 in a state where the inner bag 20 is accommodated in the outer bag 30 (the inner bag 20 is indicated by a dotted line).

  In the double fruit bag configured as described above, the lower end portion of the cut line 23 of the inner bag 20 or the lower end portion of the cut line 33 of the outer bag 30, or the cut lines 23 of both the inner bag 20 and the outer bag 30. , 33 is coated with adhesive B at the position of the lower end. In Example 2 shown in FIG. 5, the example which apply | coated the adhesive B only to the outer surface of the downward termination part of the cut line 23 of the inner bag 20 is shown. With this adhesive B, it is possible to provide the double fruit bag 40 with a strength that can withstand the tearing force, as in the first embodiment.

  As described above, the location and position of the application of the adhesive B may be any one or more of the inner bag 20 and / or the outer bag 30, or / and the outer bag 30, but considering the quality of the fruit to be included, It is desirable to apply other than inside the inner bag 30. In addition, the inner bag 20 and the outer bag can be manufactured by sticking the inner bag 20 and the outer bag 30 with a pressure-sensitive adhesive. In view of the effect that the bag 30 is not detached, it is desirable to apply at least the adhesive B to the outer surface of the inner bag 20 and / or the inner surface of the outer bag 30. In that case, the adhesive applied to the outer surface of the inner bag 20 or the inner surface of the outer bag 30 may bond the inner bag 20 and the outer bag 30, or the inner bag 20 and the outer bag 30 do not bond. In addition, mutual deviation may be allowed. In the case of Example 2 as well, the pressure-sensitive adhesive B is plastic, adhesive, pressure-sensitive adhesive, and a double-sided adhesive tape (if it is attached to the outside of the outer bag 30, a single-sided adhesive tape may be used). Etc. can be used. Thus, even if it is the double fruit bag 40, the tearing from the terminal part below the cut lines 23 and 33 can be prevented.

  Next, Example 3 will be described with reference to FIG. FIG. 6 shows the structure of a triple fruit bag. (A) shows an inner bag, (b) shows an inner bag, (c) shows an outer bag, and (d) shows a triple fruit bag in which these are stacked. Reference numeral 50 denotes an inner bag. As in the first and second embodiments, the opening 51, the cutout 52, and the cut line 53 are formed. Reference numeral 60 denotes an inner bag. The inner bag 60 is formed in a simple bag shape having only the opening 61. Reference numeral 70 denotes an outer bag, which has an opening 71, a notch 72, a cut line 73, and a clasp 74 attached thereto.

  The inner bag 50 is accommodated in the inner bag 60, and the inner bag 50 and the inner bag 60 are accommodated in the outer bag 70, whereby a triple fruit bag 80 shown in FIG. 6D is obtained (the inner bag 50 and the inner bag 60 are Dotted line display). At this time, as shown in FIG. 6 (d), the upper end portion of the opening portion 61 of the inner bag 60 is connected to the lower end portions 53 ′ below the cut line 53 of the inner bag 50 and the cut line 73 of the outer bag 70, and Each dimension is determined by a dimension located in the vicinity of 73 ′.

  In the triple fruit bag 80 shown in FIG. 6, the adhesive B as a reinforcing member is applied to the central portion near the opening on the outer side of the inner bag 61. When the inner bag 50 and the inner bag 60 are put inside the outer bag 70, the inner side of the outer bag 70 and below the end portion 73 ′ of the cut line 73 and the position of the adhesive B applied to the inner bag 60 are as follows. The adhesive B applied to the inner bag 60 absorbs the tearing force of the triple fruit bag 80, and the end portion 73 ′ of the triple fruit bag 80 can be reinforced from the inside. . Thereby, similarly to Example 1 and Example 2, the presence of the adhesive B makes it possible to give the triple fruit bag 80 strength sufficient to withstand tearing force. In addition to the above, an adhesive B may be directly reinforced from the outer surface below the terminal portion 73 ′ of the outer bag 70, and the adhesive can be applied to the inner bag 50 as long as the necessary strength can be ensured. B may be applied for reinforcement. Of course, you may apply | coat to all these positions.

  In the single or multiple fruit bags as described above, the adhesive as a reinforcing means is disposed at the lower end of the cut line formed in the fruit bag, thereby improving the tear strength of the fruit bag and opening the fruit bag. Even when a load is applied, such as when the fruit axis or branch is sandwiched in the cut line or when trying to bind the fruit bag without any gaps, the side of the fruit bag will tear continuously from the cut line. Can be suppressed. Further, since only the reinforcing means capable of withstanding the tearing force is applied to the score line, the fruit bag itself can be made of a thin and good workable material as in the prior art.

  Here, the effect of the present invention was verified by experiments. The fruit bag which is easy to hang the bag on the fruit is easy to tear from the cut line because the material is thin, and its tear strength is 267.7 mN as shown in Table 1 as the conventional product 1. On the other hand, it was possible to increase the tear strength to 333.4 mN by making the material thick like the conventional product 2. From this, it can be seen that if the tear strength of the cut line of the fruit bag is 400 mN, the tear strength is not torn from the cut line. The investigation method was carried out by a method according to JIS P 8116: Paper-Tear Strength Test Method-Elmendorf Tear Tester Method.

  However, if a material with a tear strength of 400 mN or more, such as a conventional product 2 or a fruit bag with a tear strength material or higher, is used as the material of the fruit bag, the strength of the fruit bag increases, but the material becomes harder. The thickness of the fruit bag increases, the total weight of the fruit bag increases, and a heavy burden is placed on the operator's fingers during the bagging operation.

  Then, when the same experiment was tried with respect to the fruit bag after giving the reinforcement means shown in Example 1 thru | or Example 3 mentioned above, as shown in Table 1, a reinforcement means is given. While the tear strength of the cut line part of the previous fruit bag was 267.7 mN, the tear strength of the cut line part of the fruit bag after applying the reinforcing means of Example 1 was almost doubled to 544.3 mN. The tear strength was significantly improved. In addition, a bag using the same material as the conventional product 1 and Example 1 is used as an outer bag, and an adhesive is applied to an inner bag using a material having a tear strength lower than that of the outer bag. The tear strength of the cut line portion of the fruit bag of Example 2 is 451.1 mN. Furthermore, a bag using the same material as the conventional product 1 and Example 1 is used as an outer bag, and other materials (outer bag) The inner bag using the inner bag using the inner bag and the inner bag using the inner bag, and the inner bag attached by applying an adhesive to the end of the cut line of the outer bag, that is, Example 3. It was able to be obtained as an experimental result, respectively, that the tear strength of the cut line part of the fruit bag of the aspect of becomes 725.7 mN. Thereby, in the fruit bag to which the reinforcing means of the present invention is applied, the tear strength in the vicinity of the lower end portion of the cut portion is at least 400 mN (millinewton) without increasing the fingertip force required for the bagging operation. ) It was proved that the effect is demonstrated by the above.

  A fruit bag when bagging a peach fruit, which is different from the above-described Examples 1 to 3, will be described with reference to FIGS. The peach fruit bag 90 is formed with a notch 92 so that the opening 91 can be easily opened. Peach has a short fruit axis, so it is different from Examples 1 to 3, and V-shaped cutouts 93 (both formed on both sides of the fruit bag are I-type cut lines if formed on both sides). May be formed). The peach fruit bag 90 may be formed in a round shape having an R at the tip of the V-shaped cutout portion 93 so as not to be torn during bagging. In order to further reinforce this, adhesive B is applied to the tip of the V-shaped cutout. Of course, there is no problem even if this is replaced with plastic, adhesive, reinforcing tape or the like, as in the previous embodiment.

  A procedure for bagging the peach fruit bag 90 shown in FIG. 7 on the peach fruit will be described. First, as shown in FIG. 8, the opening 91 is opened to introduce the peach fruit A ′ into the peach fruit bag 90. At that time, the peach branch is placed so as to fit into the V-shaped cutout 93. Thereafter, as shown in FIG. 9, the upper ends of the V-shaped cutout portions 93 on the near side are crossed, and the upper ends of the V-shaped cutout portions 93 on the back side are also crossed to sandwich the branch. At this time, even if a load is applied to the tip of the V-shaped cutout portion 93, the tear strength of the V-shaped cutout portion of the fruit bag is improved by the adhesive B, so that the fruit bag is not torn. Subsequently, as shown in FIG. 10, the clasp 94 is bent and the upper end of the V-shaped cutout portion is fixed so that the fruit bag 90 is not detached from the pinched branches. Pouch the peach fruit as above.

  As described above, even if it is a V-shaped cutout formed for peach fruit, it can be prevented from being torn when the fruit bag is hung by reinforcing it with an adhesive or the like. it can.

  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, although not shown, when the cut line or the cutout portion is U-shaped, the reinforcing member may be disposed so as to cover the lower portion of the U-shaped rounded end portion. Moreover, although it demonstrated as a 1 thru | or triple fruit bag in the Example, it does not limit to this, Even if it applies this invention with what piled up four or more fruit bags, there is no problem.
