Abstract
Description
[Technical Field]
[0001] This invention relates to a flexible container for storing and transporting crops such as carrots harvested by a crop harvesting machine or the like, and to a structure for keeping the top opening through which the harvested crops are put in open. [Background technology]
[0002] When vegetables such as carrots are mechanically harvested using a crop harvester, a large flexible container is attached to the crop harvester and the harvested crop is placed into it (Patent Documents 1 and 2). Near the top opening of the flexible container, hooks made by sewing both ends of a strip-shaped band to the peripheral wall are provided at appropriate intervals, and by hooking a hanging hook on the crop harvester to these hooks, the top opening is kept open so that the harvested crop can be placed into it.

[0003] [Patent Document 1] Japanese Patent Application Publication No. 10-17075 [Patent Document 2] Patent Publication No. 2021-45062 Summary of the Invention [Problem to be solved by the invention]
[0004] As described above, conventional flexible containers have required a strap-like band made of a separate piece of fabric to be sewn onto the container body to serve as a hook in order to keep the top opening open. This resulted in additional material costs for the strap-like band when manufacturing the container, and also required time and effort to sew it on.
[0005] The present invention has been made to solve the above-mentioned problems, and its object is to manufacture a flexible container capable of holding an opening at a top in a rational manner and at low cost. [Means for solving the problem]
[0006] In order to achieve the above-mentioned object, the present invention provides a flexible container for storing harvested produce, in which the upper opening of the flexible container is made by folding the upper edge outward and sewing a bag-like portion circumferentially, while any position on the bag-like portion is made an open portion that is not sewn circumferentially, and this open portion has a pair of stitching patterns on both sides as markers, and the space between the pair of stitching patterns is sewn into the shape of a pocket with an opening at the bottom edge, and a hanging hook can be inserted into this pocket-like open portion.
[0007] According to the above means, by inserting the hanging hook into the pocket-shaped opening from below and lifting up the upper opening, the upper opening can be kept open when the harvested crop is put in. Furthermore, because the pocket-shaped portion is made of fabric with the upper opening folded back, there is no need to prepare any special parts separately, and the sewn-in bin can be completed simply by sewing a stitching pattern on the left and right sides.
[0008] This stitching pattern not only reinforces the opening (on both sides), but also serves as a marker that allows the user to visually identify the position of the pocket-like opening when attaching the flexible container to a crop harvesting machine or the like.
[0009] The stitching pattern may be a complex pattern such as a floral design, but a simple pattern that does not require much sewing effort is preferable, as long as it serves as a marker to indicate the opening. Specifically, examples include squares, triangles, diamonds, polygons, circles, ellipses, and partial shapes of these (circular arcs and elliptical arcs), as well as geometric patterns that combine these. In addition, zigzag patterns, lightning bolt patterns, and letters such as the alphabet (Roman letters) are also included, and characters that can be drawn in one stroke, such as the letter Z, can be more easily formed. Note that even a single line or a single curve is included in the stitching pattern of the present invention if it serves as a marker. Furthermore, the stitching pattern does not need to span the entire vertical width (fold width) of the bag-shaped portion; for example, the stitching pattern may span half the vertical width of the bag-shaped portion.
[0010] Furthermore, if the stitching thread used for the stitching pattern is a colored thread, it will be easier to see, and in particular, by using a red thread, the position of the pocket-shaped opening can be made even more noticeable.
[0011] Furthermore, since the bag-shaped portion is hollow in the circumferential direction, by inserting a string through this bag-shaped portion and using this string to tighten the entire upper opening into a purse-like shape, the upper opening can be easily closed after the harvested product has been placed inside. [Effects of the Invention]
[0012] According to the present invention, the upper opening for putting harvested products into the container is formed by folding the upper edge outward and sewing it circumferentially to form a bag-like portion, while any position on this bag-like portion is left unsewn and an open portion is formed at any position on this bag-like portion.A pair of stitching patterns is provided on both side ends of this open portion as markers, and a pocket-like portion with an opening at the lower edge is formed between the pair of stitching patterns.A hook for hanging can be inserted into this pocket-like portion, so that when hung on a crop harvesting machine or the like, the upper opening can be easily held and attached, and manufacturing costs and effort can be reduced. [Brief explanation of the drawings]
[0013] [Figure 1] 1 is an overall perspective view of a flexible container according to an embodiment of the present invention; [Figure 2] Enlarged view of the pocket-shaped opening [Figure 3] FIG. DETAILED DESCRIPTION OF THE INVENTION
[0014] A preferred embodiment of the present invention will now be described with reference to the accompanying drawings. Fig. 1 is a perspective view of a flexible container (opened) according to one embodiment of the present invention, particularly suitable for harvesting and transporting carrots. Reference numeral 1 denotes a rectangular cylindrical body having four peripheral surfaces; 2 denotes an upper lid connected to the upper side of body 1; 3 denotes a bottom lid attached to the lower side of body 1 so as to close the lower bottom of the body; the bottom is formed by tightening four chrysanthemum-shaped pieces 3a with a string or rope 3b threaded through their lower edges. Reference numeral 4 denotes an inverted U-shaped lifting belt attached to two opposing locations on the outer surface of body 1, which is used to lift the flexible container when harvesting, transporting, or discharging carrots.
[0015] In a flexible container having such a basic configuration, the feature of the present invention is the structure of the top opening of the top lid 2. That is, the top opening of the top lid 2 is formed by folding the upper edge outward and sewing 5 the resulting lower edge to the lining fabric in the circumferential direction to form a hollow bag-like portion 6, while the above-mentioned sewing 5 is not performed at four points of this bag-like portion 6, forming an open portion 8 including an unsewn portion 7 in the circumferential direction, as shown in Figure 2.
[0016] Furthermore, as shown in Figure 2, this opening 8 has a pair of "triangular" stitching patterns 9 on both sides, and the unsewn portion 7 is sewn in the shape of a pocket with an opening between the pair of stitching patterns 9.
[0017] As shown in Figure 3, a hanging hook F can be inserted from below through the unsewn part 7 into the pocket-shaped sewn opening 8, which allows the top cover 2 to be kept open when the harvested produce is put in. At that time, the position of the opening 8 in the bag-shaped part 6 can be easily seen using the stitching pattern 9 as a guide.
[0018] In this embodiment, the stitching pattern 9 is "triangular" and its acute angles have the effect of strongly indicating the opening 8. Also, since the triangular shape can be drawn in one stroke, sewing it is relatively easy. Furthermore, by forming the stitching pattern 9 with red sewing thread, the position of the opening 8 can be made even more conspicuous.
[0019] In this way, the flexible container of this embodiment can sew a pocket-shaped opening 8 by folding back the top opening and applying the stitching pattern 9. In this case, there is absolutely no need to prepare any additional fabric, including a reinforcing fabric for the portion where the stitching pattern 9 will be applied. Nevertheless, the insertion port (opening 8) for the hanging hook can be configured in a conspicuous manner, making it possible to produce a flexible container that is extremely easy to use.
[0020] Furthermore, since the bag-shaped portion 6 is hollow in the circumferential direction, by inserting a string 10 through it, the entire upper opening of the top lid 2 can be tightened like a purse with the string 10, making it possible to close the top lid 2 after harvesting, which is very rational.
[0021] It should be noted that the above embodiment is merely one example of the present invention, and the overall shape may be cylindrical, or the bottom cover 3 may be changed to the bottom cover employed in the patented invention of Patent No. 6767787 held by the applicant of the present invention. Furthermore, the number and positions of the openings 8 may also be changed, and the stitching pattern 9 may of course be changed to another pattern. [Explanation of symbols]
