Description

  The present invention relates to a carry bag that is easy to assemble, can be used as a lightweight carry bag with casters, and can be used as it is as a packaging box for home delivery or small package shipment.

    In recent years, due to the progress of road and sidewalk maintenance, carry bags for storing and pulling luggage in a box-shaped body having casters on the bottom are widely used for travel and business trips. Since these conventional carry bags are made of metal or thick cloth, there is a limit to weight reduction.

Therefore, for example, Patent Document 1 proposes a technique in which a box-like case of a carry bag, a handle member, and the like are configured from an assembly of cardboard materials.

  In the inventions of Patent Documents 1 and 2, since a carry bag is produced using a cardboard-like material, it is considered that the weight can be reduced as compared with the conventional one, but a box-shaped case, a handle member, a handle holding member, etc. Since it is necessary to assemble them individually after forming them individually with a cardboard-like material, the production work of the carry bag becomes complicated. Moreover, since one cardboard-like material is required for each member, a plurality of cardboard-like materials having different shapes are required to produce one carry bag, and the distribution and storage of the cardboard-like material is complicated. It becomes.

  In the idea of Patent Document 3, a handle is integrally provided on the main body to improve the assemblability and reduce the weight, but only considerations regarding the use as a carry bag and its disposal have been made. Patent Document 3 is also considered to be used as a box for home delivery or the like, but a lid portion covering the upper opening of the box-shaped main body in that case is provided separately from the handle, and the handle is cut or folded into the box. There is a waste of installing a lid member separately from the handle.

  The present invention has been made in view of such conventional problems, and its purpose is to reduce the weight and to simplify the assembly and disassembly work, as well as to deliver the articles contained in the carry bag. In this case, the carry bag can be used as it is as a packaging box for home delivery, and a carry bag having no useless parts is provided.

The present invention is a carry bag. First, the invention of claim 1 is arranged such that a rotatable caster 2 is detachably disposed at the bottom of a box-shaped main body 1, and at least from the back of the box-shaped main body 1 opened upward. The handle piece 3 extended upward is folded so that the upper opening 4 of the box-shaped main body 1 can be closed, and the device of the second item is a cardboard in which the box-shaped main body 1 and the handle piece 3 are continuously integrated. It was formed by.

  The invention of claim 3 is such that reinforcing side pieces 5, 5 extending upward from both sides of the box-shaped main body 1 are made to be continuous with both sides of the handle piece 3. The caster 2 having the split groove 12 is attached to the shaft cylinder 9 to which the caster 2 is attached, and the stopper 10 is press-fitted into the shaft cylinder 9. The device is provided with a spiral protrusion 11 on the outer periphery of the stopper 10 to facilitate the removal of the stopper 10.

  In the present invention, the rotatable caster 2 is detachably disposed at the bottom of the box-shaped main body 1 as described above, and at least the handle piece 3 extending upward from the back of the box-shaped main body 1 opened upward is folded. Since the upper opening 4 of the box-shaped main body 1 can be closed, the main use is that the box-shaped main body 1 accommodates pamphlets and various purchased items inside the upper opening 4, has a handle piece 3, and casters 2. It can be rolled and used as a carry bag. When you want to ship this by postal parcel or courier, you can fold the handle piece 3 and use it as a lid to cover the upper opening 4 of the box-like body 1 without having to replace the contents of the carry bag with another box. It is convenient because it is good.

  Further, when the box-shaped main body 1 and the handle piece 3 are formed of a single continuous cardboard, it can be easily assembled by folding a sheet material such as a single cardboard and joining the joints.

  The caster 2 can be made of any suitable material such as plastic, aluminum, cardboard, cardboard, etc. When it is made of cardboard, of course, there is a limit to the excessive load, but it is relatively strong despite being lightweight. The short-sized contents can be made into a box-shaped main body 1 and the caster 2 can be rolled and moved.

  Further, when the reinforcing side pieces 5 and 5 extending upward from both sides of the box-shaped main body 1 are made continuous with both sides of the handle piece 3, the strength of the handle piece 3 is higher than that of the handle piece 3 alone. As a result, the handle piece 3 is difficult to break and durability is improved. Moreover, when the handle piece 3 is folded, the reinforcing side piece 5 can be easily folded along the fold line or the like, so there is no problem.

  After mounting the shaft cylinder 9 of the caster 2 through the bottom of the box-shaped main body 1 and attaching the casters 2 to both ends of the shaft cylinder 9 exposed, the stopper 10 is applied to the end of the shaft cylinder 9 as a stopper. As a result, it is simpler and easier to install than various conventional casters, and the caster 2 can be pulled out of the shaft tube 9 before assembly, so that the whole can be designed compactly.

  The best mode for carrying out the present invention will be described below in detail with reference to the drawings. FIG. 1 shows a state when used as a carry bag, and FIG. 2 shows a state where the upper opening 7 is covered with a handle piece 3 as a lid. FIG. 3 shows the unfolded state before assembling them. A front part 1c is continuously provided on one side of the back part 1a via a side part 1b, and another side part 1b is provided continuously from the front part 1c. The side portion 1b is glued with an overlap margin 1d and joined to the front portion 1a.

  A handle piece 3 extends from the upper side of the back portion 1a via a broken line, and auxiliary side pieces 5 and 5 extend from the upper side of the side portions 1b and 1b via the broken line. One of the auxiliary side pieces 5 is connected to one side of the handle piece 3 by a broken line, while the other auxiliary piece 5 is connected to the other side of the handle piece 3 by gluing the overlap margin 1d. And the handle piece 3 and the auxiliary | assistant side piece 5 are set so that it can fold by these broken lines and can cover the upper opening 4 of the box-shaped main body 1. FIG. Furthermore, the upper end of the handle piece 3 is folded back to have a double structure, so that the strength can be improved. 7 is a grip hole.

  Bottom portions 1e and 1g are extended from the lower ends of the back portion 1a and the front portion 1c via broken lines, and overlapping margins 1f and 1h are extended from the lower ends of the side portions 1b and 1b via the broken lines. Here, in the illustrated example, a crest 1i and a trough 1j are provided on each of the bottoms 1e and 1g, and one of the crests 1f and 1h is joined to each other by gluing, and the crest 1i as shown in FIG. And the valley 1j are engaged with each other so that the bottom can be easily configured.

Further, a folding part 6 that can be formed by pushing a part of the lower end of the box-shaped main body 1 inwardly by a solid line incision and a broken line by a broken line on the back part 1a and the bottom part 1e, if necessary, on the side parts 1b, 1b, etc. 6 ... are put in place, and by pushing them into the inside, the shaft tube 9 is attached to the lower end of the handle piece 3 side (or the front part 1c side) of the box-shaped main body 1 so as to be exposed at both exposed ends. The caster 2 is attached. In addition, you may make it form the stand 8 in the opposing edge part in which this folding part 6 is not provided by cutting and raising with a cut line and a broken line.

  Here, the material of the box-shaped main body 1 is formed of cardboard or cardboard, and the box-shaped main body 1 opened at least at the top as shown in FIG. 1 by assembling the box-shaped main body has a handle piece 3 above the back. It is extended to. The handle piece 3 functions as a handle when used as a carry bag, and functions as a lid that covers the upper opening 4 of the box-shaped main body 1 by folding the handle piece 3 along a broken line when stored or delivered. Further, the left and right sides of the handle piece 3 and the left and right edges of the upper opening 4 adjacent to the handle piece 3 are integrally connected by reinforcing side pieces 5 and 5 as necessary. In this case, it is preferable that the reinforcing side piece 5 is also provided with a fold line (broken line in the figure) so that it can be easily folded. A part of the auxiliary side piece 5 may be cut.

  A cylindrical tube 9 is inserted into the box-shaped main body 1 by using a gap formed by inserting a cut and a fold line at a lower corner of the box-shaped main body 1 or in an appropriate place between the lower-end corners and pushing in the fold-in portions 6, 6. Disc-shaped casters 2 are attached to both ends of the shaft tube 9 that protrudes left and right from the bottom of the lower end of 1. Here, the shaft tube 9 is formed by rolling cardboard or cardboard, and the caster 2 can also be made of cardboard. However, the shaft tube 9 and the caster 2 are made of materials other than cardboard, such as cardboard, plastic, aluminum, and other metals. It may be made of wood material. The caster 2 is mounted on the shaft tube 9 and locked, but a retaining pin may be inserted outside the caster 2 or a screwed lid 10 as shown in the figure may be mounted. The casters 2 may be installed on both the front and rear sides.

FIG. 4 shows an example of a stopper 10 using a screw-on lid. The stopper 10 has an insertion cylinder portion slightly thicker than the inner diameter of the shaft cylinder 9 and is an insertion cylinder that is press-fitted into the end of the shaft cylinder 9. A spiral non-slip protrusion 11 and a split groove 12 in a direction parallel to the shaft are provided on the outer periphery of the shaft. It is possible to prevent the caster 2 from coming off by press-fitting into. When removing, if the gripper part of the stopper 10 is held and rotated, the anti-slip protrusion 11 can be easily removed if it is spiral.
