Description

  The present invention relates to a binding tool in which an opening of a packaging bag filled with food and a planar shape for binding a bundle of other articles are substantially C-shaped.

  As shown in FIG. 10, it is conventionally known that the opening 3 of the packaging bag 2 filled with the articles 1 such as sliced bread is bundled and bound by the binding tool 4. And as this binding tool 4, as shown in FIG. 11, the main-body part 5 formed from one piece of synthetic resin with comparatively poor flexibility and having a substantially C-shaped planar shape, and the bundle of articles are inserted. The binding portion 6 and the insertion portion 7 that pushes the opening 3 of the packaging bag 2 in the direction of the arrow Y through the binding portion 6 (US Pat. No. 3,164,250 specification).

  In the binding tool 4 having such a structure, the effect that the opening 3 of the packaging bag 2 surrounded by the binding part 6 can be surely bound is exhibited, but the necessity for resource saving is further emphasized. However, there is a problem that the amount of the synthetic resin used for each binding tool 4 is large.

U.S. Pat. No. 3,164,250

  Therefore, in order to solve the above-mentioned problem, it is only necessary to make the tying tool itself thinner. However, if the tying tool is made thinner, the physical performance of the tying tool decreases accordingly. Therefore, in order to save resources of the binding tool, it is necessary to suppress physical deterioration of the binding tool. An object of the present invention is to save resources of a binding tool while suppressing a decrease in physical performance.

  In order to solve the above-described problems, the present invention is configured such that the binding tool is composed of a main body portion in which a plane made of a piece of synthetic resin is substantially C-shaped, and a rib portion protruding to one side thereof. As a result, it is possible to reduce the amount of synthetic resin used to form the main body from the binding device according to the known technique, and it is possible to suppress physical deterioration of the main body due to the thin main body. In the present invention, the rib portion is originally formed from a flat surface at a specific portion in the binding portion, and when an external force is applied to the specific portion, the vertical component of the external force acting on the specific portion is used. It means continuous or discontinuous deformation processing that resists.

  In order to achieve the above-described problem more effectively, the present invention provides a first rib portion provided in the outer peripheral region of the main body portion and a second rib provided in the inner peripheral region as the rib portion. Three types of rib portions, that is, a third rib portion formed in the plane region of the portion and the main body, are provided to the main body portion. The first rib portion is an inclined rib that reinforces the outer peripheral region of the main body portion, and the second rib and the third rib are groove ribs that reinforce the inner peripheral region and the planar region, respectively. As a shape of the binding tool that realizes such a rib, the main body portion has a leaf shape.

  The present invention is excellent in that it can reduce the amount of synthetic resin used in a binding tool in which a planar shape for binding a bundle of articles is formed in a substantially C shape while suppressing a decrease in physical performance with respect to the binding tool. Demonstrate the effect.

  Next, the best mode for carrying out the present invention will be described in detail with reference to the drawings. As shown in FIG. 1, FIG. 2, FIG. 3, FIG. 4 and FIG. 5, a tying member 10 according to the present invention is made of a single piece of synthetic resin, and the leaf-shaped main body of which the plane forms a substantially lateral C shape. 12 and a plurality of and a plurality of types of rib portions 14 projecting to the back side, which is one side thereof.

  Further, the body portion 12 has a Ω-shaped shape that keeps a bundled portion of articles bundled (described later), for example, as shown in FIG. A binding region 16 and an insertion region 18 that connects the binding region 16 and the peripheral region 20 of the main body 12 are formed. A guide region 19 is formed between the peripheral region 20 and the insertion region 18 so as to expand outward in a substantially V shape, and the three regions 18, 19, 20 are smoothly continuous. ing. A plurality of sharp protrusions 17 are formed in the binding area 16 to increase the frictional resistance against the bundled portion of the article.

  In addition, the peripheral region 20 is provided with an inclined rib 141 whose outer peripheral end is inclined to the back surface side as the first rib of the main body portion 12, which increases the bending strength of the main body portion 12 and also bundles articles. The touch to the part is softened.

  Similarly, a groove rib 142 is cantilevered on the leading end side of the inclined rib as a second rib in the binding area 16 and the insertion area 18. In the present invention, the groove rib 142 is referred to as a cantilever groove rib.

  Further, a leaf-like groove rib 143 deeper than the depth of the cantilever groove rib 142 is formed as a third rib in the center of the main body portion 12.

  The binding device 10 according to the present invention having such a shape and structure is formed by press-molding a sheet of engineering resin such as a flexible synthetic resin, for example, polyethylene terephthalate or polybutylene terephthalate, as shown in FIG. In addition, it is obtained by a method in which a plurality of binding devices 10 are once formed as a connection body 22 having a structure in which a plurality of binding devices 10 are connected and then separated into individual binding devices 10. In addition, the connecting part 24 which connects each binding tool 10 in the connection body 22 is provided with a break line 26 in advance, and by breaking the break line 26, the plurality of binding tools 10 from the connection body 22. Are separated.

  Next, the operation and effect of the binding tool configured as described above will be described. When binding a bound portion of an article to the binding tool, the binding tool according to the related art is indicated by an arrow Y in FIG. The bundled opening 3 of the article 1 is pressed in the direction. In the binding tool 10 of the present invention, as shown in FIGS. 2, 7 and 8, the direction of the arrow X inclined from the arrow Y is shown. The bound portion 28 of the article is pressed toward the object. At this time, since the first rib 141 is a pair of inclined ribs in the guide region 19 and the peripheral region 20 of the binding tool 10 according to the present invention, the pair of inclined ribs first receives the bound portion 28 of the article. .

  Subsequently, as shown in FIG. 9, the pair of insertion regions 18 in the binding tool 10 are pushed down by the bound portion 28 of the inclined article, widen the gap between them, and finally the bound portion 28 of the article is moved. As shown by the one-dot chain line in FIG. 2, the binding region 16 surrounds the bound portion 28 of the article. Since the cantilever rib 142 protrudes from the binding area 16 and the sharp protrusion 17 is present at a part thereof, they securely bind and hold the bound portion 28 of the article.

  Since the first, second, and third ribs 141, 142, and 143 exist in the binding device 10 that once holds the bound portion 28 of the article, the main body 12 itself exhibits bending deformation resistance. In particular, the cantilever groove rib 142, which is the second rib having a shallower depth than the groove rib 143 of the third rib, exhibits higher bending deformation resistance than the other ribs, and firmly holds the bound portion 28 of the article. To do. Therefore, since the bending deformation resistance can be increased as compared with the case where the main body portion 12 is simply formed from a flat synthetic resin piece, the thickness of the main body portion can be reduced corresponding to the increase in bending deformation resistance, and as a result, The present invention exhibits the effect that the amount of synthetic resin consumed per binding tool can be reduced.

  Further, the direction X of pressing the bound portion 28 of the article against the binding tool 10 according to the present invention is not only different from the pressing direction Y of the binding tool according to the prior art, but also the bound portion 28 of the article is the first. Since the rib is pressed against the inclined rib 141, the feel of the bound portion 28 of the article against the binding tool 10 is softened. As a result, the pressing force of the bound portion 28 of the article against the binding tool 10 can be reduced. As a result, damage to the article can be reduced.

  This fact exhibits an additional effect that only a small release force is required when unbinding the articles once bound to the binding tool 10. As shown in FIG. 12, for example, in order to release the binding tool 4 according to the prior art from the article, it is necessary to alternately separate the pair of insertion portions 7 with fingers, and it is necessary to apply a considerable separation force at this time. However, in the binding tool 4 according to the present invention, since the first rib is not the groove rib but the inclined rib 141, the pair of insertion regions 18 can be separated with a relatively small separation force. .

  In this invention, since the 3rd rib 143 extended to the flat part of the main-body part 12 has a vein shape, the effect of improving the designability of the external appearance of the binding tool 10 formed in the leaf shape of a tree is exhibited.

  The present invention can be carried out by changing a part of the embodiment as long as it follows the fundamental technical idea and does not significantly impair the effects of the invention.

  The present invention can be widely used in the field of binding bundled articles.
