Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to a packaging box, and more particularly to an improvement in a packaging box having a handle.

0002

[Conventional technology]

Packaging boxes are often fitted with handles to make them easier to carry. It is being said. This handle is described in Japanese Utility Model Application Publication No. 2-131935. Are known. This handle has an insertion part on both ends of the handle that is inserted into the insertion hole of the box. However, a pair of hook portions are formed projecting from this insertion portion. To attach this handle to a box, insert the handle into the box's insertion hole and insert it through the center of the box. After inserting it, pull it out in the opposite direction. At this time, the hook part bends inward. This allows it to be inserted into the insertion hole, and after insertion, it expands outward (in the width direction) to It gets caught in the hole.

0003

[Problem that the idea aims to solve]

In this way, in the above-mentioned handle, in order to make the hook part easier to bend inward, In addition, it is necessary to form the hook portion to extend greatly from the center of the handle, and For the same purpose, it is preferable to form a large cutout hole in the center of the insertion part. It is. However, since the hook needs to extend far beyond the center of the handle, this is not possible. If you try to manufacture the entire handle by cutting it out of a strip of material, you will end up with a large overhanging pull. It becomes necessary to set the width between the hanging parts to the width of the strip material. Therefore, the central part of the handle If this happens, there will be a large surplus of material in the strip, and all of this surplus will be wasted. , it is not possible to make effective use of materials. Also, it is preferable to form a large notch hole in the center of the insertion part; In order to make it easier for the hook to bend inward, the cutout hole should be made through the hole. It needs to be a through hole. However, when forming the through holes by punching, the punching did not work properly. In many cases, the quality of the product is not maintained, increasing the incidence of defective products. Moreover, the cutout hole is large. The more you do this, the more likely it is that the hook will bend inward. However, on the contrary, there is a problem in that the strength of the insertion portion decreases.

0004 Moreover, in the above handle, the width of the center part of the handle is smaller than the insertion hole of the box. It is set so that the center part is inserted into the insertion hole when installing the handle. be. However, when bending the hook inward and inserting it, there is considerable resistance. Conversely, when the hook passes through the insertion hole, this resistance suddenly disappears. Besides that As a result, the center part of the handle that follows this may be inserted deeper than necessary, and the handle may become loose after insertion. When pulling out the handle in the opposite direction, it becomes necessary to pull it out further than necessary, making it difficult to attach the handle. It takes a lot of time to do the work.

[0005] Furthermore, in the above-mentioned handle, since the insertion depth of the handle is fixed at a fixed position, No consideration has been given to Therefore, when packing with the handle attached, This handle may protrude beyond the box, making it difficult to grasp it during packing. It is not necessary to remove the hand or insert the handle deeply into the insertion hole. Ru. Conversely, when carrying the box, the handle is inserted shallowly into the insertion hole and the handle is It is easier to reach into the handle if it remains larger than the box, making it easier to use. It is advantageous. However, no consideration was given to fixing the insertion depth of the handle at a fixed position. Because the handle is not inserted deeply into the insertion hole, when holding the handle, the handle is inserted deeply into the insertion hole. The problem arises that it is necessary to extract the

[0006]

[Means to solve the problem]

Therefore, the first invention of the present application is to provide a packaging box having the following configuration. and solve the above problems. The packaging box according to the first invention of the present application has a box body 1 and a box that is passed between two points of this box body. The box body is provided with a handle 2, and an insertion hole 12 is formed at each of two points on the box body. The central portion 3 of the handle is shaped like a band having a width greater than the width of the insertion hole 12. At both ends of this handle, insertion parts 4, 4 are formed which are respectively inserted into the two insertion holes mentioned above. has been done. Each insertion portion 4 extends integrally from the 3 ends of the central portion of the handle and is wider than the central portion. a small neck portion 5; a tapered portion 6 integrally extending at the tip of the neck portion; It extends rearward from both sides of the tapered part of the handle and is bent toward the back of the handle. A pair of engaging pieces 7, 7 are provided. The length between the outer sides of the engaging pieces 7, 7 of each insertion part is equal to the width of the insertion hole 12 of the box body. The width of the neck portion 5 of each insertion portion is larger than that of the insertion hole in the box body. The width is set to 12 or less. Then, bend the insertion part 4 of the handle in a substantially V-shape at approximately the center in the width direction and insert it into the box body. By inserting it into the entry hole 12 and pulling the insertion part 4 of the handle in the opposite direction to the insertion direction. , the engaging pieces 7, 7 are engaged with the back surface of the insertion hole. Further, the second invention of the present application provides a packaging box having the following features in addition to the above configuration. By doing so, the above problem is solved. That is, the central portion 3 of the handle has a constant width over substantially its entire length in the longitudinal direction. It is in the shape of a band, and the maximum width of each insertion portion 4 is equal to the above-mentioned constant width of the central portion 3 of the handle. It is set as below. The insertion portion 4 is formed in a fold formed approximately in the widthwise center of the handle. In addition, the neck portion 5 of each insertion part has a small line 8 near the distal end and near the proximal end. Convex portions 51 and 52 protruding in the width direction are formed on at least one side, and these convex portions are inserted. It is characterized by being something that locks into a hole.

[0007]

[Effect]

In the present invention, the handle 2 is bent in a substantially V-shape from the center of the insertion portion 4, and It is inserted into the insertion hole 12 of the main body 1. This allows the insertion part 4 to be inserted into the insertion hole 1 of the box body 1. You will be able to pass 2. Here, the width of the insertion hole 12 is the width of the center part 3 of the handle. Because the width is smaller than the width of the handle, the three ends of the center part of the handle come into contact with the outer wall surface of the insertion hole 12, and the middle part The central portion 3 never enters the insertion hole 12. Pass through the insertion hole 12 and enter the box body. The engaging pieces 7, 7 of the insertion part that have entered the The entry portion 4 naturally returns from the V-shaped state to the flat shape before insertion. In this state, pull the handle. When lifted up, the tip of the neck portion 5 of the handle can be pulled out of the insertion hole 12. becomes. At this time, the distance between the outer sides of the engaging pieces 7, 7 is larger than the width of the insertion hole 12. Therefore, the engaging pieces 7, 7 cannot pass through the insertion hole 12 and are bent in the rearward direction. It is left behind on the inner surface of the insertion hole in an open state and engages with the inner surface of the insertion hole. Furthermore, by forming the first convex portion 51 near the base end of the neck portion 5, the handle can be It is lightly fixed in the same position and prevents the handle from accidentally lifting up. or By forming the second convex portion 52 near the tip of the neck portion 5, the handle is pulled up. It can be easily fixed with the handle, and the handle makes it easy to grab when carrying it. It is something.

【Example】

Hereinafter, embodiments of the present invention will be described based on the drawings. Figure 1 is a plan view of a handle according to an embodiment of the present invention, and Figure 2 is an overall perspective view of an embodiment of the present invention. It is a diagram.

[0009] This packaging box includes a box body 1 made of paper or the like having two opposing sides; The handle 2 is provided between two sides of the handle 2. This box body 1 has a rectangular parallelepiped shape, but it can be modified into other shapes as appropriate. It is possible. An insertion hole 12 is formed in each of the opposing sides 11 of this box body. ing.

0010 Next, the handle 2 has a central portion 3 having a certain width larger than the width of the insertion hole 12. Forms a band. In this central part 3, bending lines 31, 31 are formed at two places. As a result, the central portion 3 is divided into a top surface corresponding portion 32 and side surface corresponding portions 33, 33. It is. The length between the bending lines 31, 31, that is, the length of the upper surface corresponding portion 32 is set approximately equal to the length of the top surface 13 of the box body 1. Also, the bending line 31 The length between 3 and the insertion hole 12. And inside this handle Insertion parts 4 inserted into the insertion holes 12 are formed at both ends of the central part. This insertion portion 4 is composed of a neck portion 5, a tapered portion 6, and a pair of engagement pieces 7, 7. has been completed.

[0011] The neck portion 5 extends integrally from the end of the central portion 3 of the handle, and has a width corresponding to the width of the central portion 3 and the box body. The width of the insertion hole 12 is smaller than that of the insertion hole 12. Near the proximal end of this neck part, there is a first Convex portions 51 are formed to protrude on both sides. Also, near the tip of the neck, The second convex portion 52 is formed to protrude on both sides. This first convex portion 51, 51 The length between them and the length between the second protrusions 52, 52 are respectively the width of the insertion hole 12 of the box body. It is preferable to set it to be approximately equal or slightly larger.

0012 The tapered portion 6 extends integrally with the tip of the neck portion, and its base end is connected to the neck portion. It is wider than the portion 5, and becomes smaller toward the tip. to this This makes insertion into the insertion hole 12 of the box body easier.

[0013] The engagement pieces 7 extend rearward from both sides of the tapered portion 6, and The flexibility of the material allows it to bend toward the back of the handle. In addition, the bend It is also possible to form a crease line to make it easier to fold. The length between the outer sides of the engaging pieces 7, 7 is the maximum width of the insertion part, and this width is The width is set larger than the width of the insertion hole 12 of the body. Also, in this example, this is equal to the above-mentioned constant width of the central part 3 of the handle, but smaller than the width of the central part 3. It is also possible to do so.

[0014] In the insertion portion 4 having the above configuration, from the neck portion 5 to the tapered portion 6 A bending line 8 is formed in the center. This bending line 8 will be described later. This is to facilitate the insertion work and does not necessarily need to be provided. In this embodiment, a groove is used as the bending line 8, but from the back side It is also possible to make a small width score line that penetrates the surface. Also, in the example is a continuous line from the neck portion 5 to the tapered portion 6, but there are intermittently grooves or Alternatively, a score line may be added.

[0015] As shown in FIG. 9, this handle 2 is made by molding a continuous tape 101 made of synthetic resin. 102, 102 can be cut and manufactured. This tape width is The width of the central part 3 of the handle may be equal to the width of the central part 3 of the handle. Handles can be manufactured by simply cutting from scratch without any other processing. Ru. Preferably, the mold 102 is provided with cutting blades in the shape of the insertion portion 4 symmetrically. This allows you to cut the insertion part on the rear end side of the leading handle and the rear end of the handle in one cutting operation. It is possible to cut the insertion part on the distal end side of the attached handle at the same time, and it is possible to cut both parts at the same time. Detachment can be performed. Moreover, as mentioned above, the maximum width of the insertion portion can be set to be less than or equal to the width of the central portion 3 of the handle. This prevents excess tape from appearing in the center of the handle, and reduces the amount of material. Effective use can be made. In addition to synthetic resin, the material of the handle may be paper, cloth, etc. with appropriate flexibility and strength. The obtained materials can be appropriately selected and used.

[0016] Next, in order to attach this handle 2 to the box body 1, attach the handle to two locations on the center part 3. After bending from the bending lines 31, 31, insert the insertion parts 4, 4 into the insertion holes 12 of the box body. insert. During this insertion, insert the insertion part 4 of the handle 2 into a V-shape from the center in the width direction. bend it to See Figures 3 and 4. This allows the insertion part 4 to be inserted into the insertion hole 12 of the box body 1. You will be able to pass. Of course, the insertion hole 12 allows the V-shaped insertion portion 4 to pass through. It needs to have an appropriate width and height so that it can be used.

[0017] Here, as mentioned above, the width of the insertion hole 12 is smaller than the width of the central part 3 of the handle. Therefore, the 3 ends of the center part of the handle come into contact with the outer wall surface of the insertion hole 12, and the center part 3 comes into contact with the outer wall surface of the insertion hole 1. 2 will not be entered. See Figures 5 and 6. Moreover, in this embodiment, the first convex portion 51 protrudes from both sides near the base end of the neck portion 5. Since the insertion hole 12 is formed between the first convex portion 51 and the third end of the central portion, will be pinched, and the handle will be lightly fixed in the same position. And as mentioned above The length of the upper surface corresponding portion 32 of the handle is set approximately equal to the length of the upper surface 13 of the box body 1. In addition, the length of the side surface corresponding portion 33 is the length between the top surface 13 of the box body and the insertion hole 12. Since the handle is set approximately equal to the shape of the box body, the handle can be easily moved It will be fixed. This may cause the handle to lift up from the box body. There is no handle, so when packing the box body, you can pack it like a normal box body without worrying about the presence of the handle. You can proceed with your work. The engagement pieces 7, 7 of the insertion part of the handle pass through the insertion hole 12 and enter the box body. Therefore, the insertion portion 4 naturally returns from the V-shaped state to the state close to the flat state before insertion. ing.

[0018] Next, to carry the box body by the handle, connect the upper surface corresponding part 33 of the handle and the box body. Insert your hand between the top surface 13 and pull up. As a result, the first convex portion 51 and the insertion The light engagement with the hole 12 is released, and the tip of the neck portion 5 of the handle is pulled out of the insertion hole 12. It is brought out. At this time, the distance between the outer sides of the engaging pieces 7, 7 is smaller than the width of the insertion hole 12. is also large, so the engaging pieces 7, 7 cannot pass through the insertion hole 12, and the engagement pieces 7, 7 cannot pass through the insertion hole 12, It is left behind on the inner surface of the insertion hole in a bent state and engages with the inner surface of the insertion hole. Figure 7, fig. See 8. Moreover, in this embodiment, the second convex portion 52 is stretched on both sides near the tip of the neck portion 5. It is designed to come out. Therefore, there is no insertion between the second convex portion 52 and the tapered portion 6. The entry hole 12 is in a state of being pinched, and the handle is lightly fixed in the same position. This results in The handle is lightly fixed in the pulled up state, and the upper surface corresponding part 32 of the handle is connected to the box body. An appropriate distance is maintained between the top surface 13 and the top surface 13. Therefore, future luck The upper surface corresponding portion 32 of the handle is designed so that it can be grasped very easily. become.

[0019] Note that the present invention is not limited to the above embodiments, and the gist of the claims It may be implemented with appropriate changes within the scope of the above. For example, the typical shape of the box body is a rectangular parallelepiped, but other shapes such as a cylinder, a polygonal prism, etc. It is also possible to change the shape to other shapes such as a cylinder or a polygonal prism. Also, the handle In addition to passing it between the sides, for example, there are two insertion holes on the top of the box body. It may also be installed so that the handle is along only the top surface. Also, there may be powder etc. inside the box body. When storing the box, double the entire box body or just the part that corresponds to the back side of the insertion hole. It is also a good idea to have a structure that prevents stored items from spilling out of the insertion hole. stomach.

[0020] In addition to the shape shown in the figure, the insertion hole 12 has a shape that allows the insertion portion 4 bent in a substantially V-shape to pass through. As long as the shape can be obtained, the shape can be changed as appropriate. The shape for bending the insertion part of the handle is approximately V-shaped, but for example, the bending line 8 Two or more may be formed in parallel, and in this case, the shape to be bent is close to a U-shape. becomes. The first and second convex portions 51 and 52 on the neck portion of the insertion portion do not necessarily need to be provided. In addition, the shape may be changed to a shape suitable for light fixing, such as a saw blade shape. can be changed.

[0021]

[Effect of the idea]

The first idea of the present application is to bend the insertion part in a V-shape and insert it into the insertion hole, and bend it toward the back side. In order to engage the insertion hole with the engaging piece, the hook part should be wide from the center of the handle. There is no need to form an overhang, and there is no need to form a cutout hole in the center of the insertion part. Nor. Therefore, the handle can be easily designed and manufactured, and the entire handle can be made from a strip of material. Even when manufacturing by cutting, it is important not only that there is no large surplus part, but also that there is no need to cut out the cutout hole. This can solve the problem that the strength of the insertion portion is reduced due to the presence of the insertion portion. Moreover, in the handle of the first invention of the present application, the box book is located at the central end of the handle. This prevents the body from entering the insertion hole, so when installing the handle, make sure that the center of the handle is not inserted. This allows the handle to be attached smoothly.

[0022] Furthermore, in the second invention of the present application, in addition to the above effects, the insertion depth of the handle is increased. Because it can be fixed in a fixed position, the handle does not lift up and interfere with packing work. It never happens. Also, when carrying the box, be sure to pull out the handle one by one. The problem of having to do this can also be solved.
