Description

[Detailed explanation of the invention] <Industrial application field> This invention is a portable packaging box (commonly called a service box) that stores portable packaging boxes for cakes, Japanese sweets, etc., and other small items. ), etc., regarding the mounting structure of the handle.

<Prior art> Conventionally, when a handle is attached to a box for storing cakes, confectionery, small items, etc. at a store or the like and handing it to a customer to make it easier to carry, the box has a certain degree of rigidity so as to maintain a certain shape. For example, a band-shaped handle made of paper or synthetic resin having a structure such as that shown in FIGS. 4 and 5 is used so that it can be attached as necessary.

In the above structure, engagement protrusions 2, 2 are protruded from the upper ends of the peripheral wall of the box 1 at corresponding positions, and both ends of the band-like handle 3 are engaged with each protrusion 2. In this case, the handle As shown in FIG. 4, inward engaging hooks 4 are bent at both ends of the protrusion 2, and a horizontal cut hole 5 corresponding to the width of the band is formed on the protrusion 2 side, into which the tip of the hook 4 is inserted. is provided, and the hook 4 is inserted into the notch hole 5 and locked therein.

<Problems to be solved by the invention> The conventional handle attachment structure as described above is convenient in that the handle can be attached and handed over at a store if necessary, but it is necessary to provide a protrusion that protrudes from the top surface of the box. If the handle 3 is stuck, it may break or become a hindrance when handling the box, and it is impossible to stack the boxes, or if both ends of the handle 3 descend downwards, they tend to disengage.

Furthermore, in the above structure, the locking part and the protrusion 2 on the hook side
Since the cut holes 2 on the sides contact and engage on a straight line in the horizontal direction, when the handle 3 is tilted with respect to the vertical line, for example when the handle is held together with other baggage, the box body 1 also This has the disadvantage that it tilts accordingly, causing cakes, soft Japanese sweets, etc. to lose their shape.

<Means for Solving the Problems> In order to solve the above problems, the handle mounting structure of the present invention has fixed positions at corresponding positions on the peripheral walls 13, 13 of the box body 11 made of an elastic member. An engaging portion 15b of the handle 15 is formed with a horizontal insertion hole 16 having a width from left to right, and the tips of the band-like portions 15a at both ends are folded inward and fixed in an overlapping state.
In the structure in which the engaging portion 15b is locked in the insertion hole 16 by inserting the engaging portion 15b into the insertion hole,
The folded end portion of b forms a curved mountain-shaped arc portion 15c and is formed as a stepped locking surface that intersects with the inner surface of the band portion 15a,
When the engaging portion 15b is inserted into the insertion hole 16 of the box body 11 and the handle 15 is lifted upward, the locking surface comes into contact with the insertion hole 16, and the engaging portion 15b is inserted into the insertion hole 1.
Further, a tongue-like piece 15e is cut out and formed in the center of the engaging part 15b, and when the engaging part 15b is bent, the extended end of the band-like part 15a is cut out. It is distinctive in that it is left unbent and protrudes downward.

<Function> The handle 15 has both ends inserted into each insertion hole 1 of the peripheral wall 13.
By inserting and locking into 6, it functions as a handle,
When inserting the above, the tongue-shaped piece 15 is inserted as shown in Fig. 1C.
e, insert it smoothly while guiding it to spread the insertion hole 16, and after inserting it, proceed as shown in Fig.
As long as the band-like part 15a is pulled upward as shown in B, the upper end of the engaging part 15b is locked in contact with the arc-shaped part 15c and the upper surface of the insertion hole 16, and the contact part is the handle 15 relative to the box body 11.
Even if the center of the box 11 is tilted, it always rolls along the arcuate portion 15c, and the box 11 always maintains a horizontal stable state due to the weight of the contents and the box 11. Further, the inserted engaging portion 15b can be easily pulled out by tilting the band-like portion 15a away from the box drawing to push open the insertion hole 16. Further, the tongue-shaped piece 15e pushes the peripheral wall of the box body 11 outward with its back surface, thereby constantly keeping the upper surface of the insertion hole 16 in the engagement portion 1.
It is pressed against the band-shaped portion 15a so as not to come off from the band-like portion 5b.

<Example> Figures 1 to 3 show an example of this invention.
A box body 11 made of paperboard has a lid body 1 that opens and closes from both ends of the top surface.
2, 12, two pairs of corresponding peripheral walls 13, 1
It is a rectangular box with a lid 12, 1
2 is opened and a cake, etc. is stored inside.

Each of the peripheral walls 13, 13 constituting the end face in the longitudinal direction is provided with a handle 1 made of paper or a synthetic resin band having a certain thickness, width, elasticity, and certain rigidity.
Both ends of 5 are inserted and locked. That is, each peripheral wall 13
Approximately at the center of the handle 15, there is provided a groove that prevents cracking from the end of the insertion hole 16 when the end of the handle 15 is inserted, facilitates the insertion, and ensures engagement of the engaging portion 15b described later. For this purpose, an insertion hole 16 is provided which has upwardly curved or bent relief portions 16a at both ends and is formed by a chevron-shaped or horizontal cut line with a width approximately equal to or larger than the width of the handle 15. The insertion hole 1
6 may be in the form of a long hole having a constant width in the vertical direction. Further, in the illustrated example, an upward notch 16b is formed in the center of the insertion hole 16, and the handle 15
The structure is such that it can be easily inserted. Handle 15
Both ends have engaging portions 15b made of folded pieces that are folded back to one side at folds 15d, overlap the band-like portion 15a, and are adhesively fixed, and the engaging portions 15b
As shown in the figure, the folded upper end portion forms an upwardly curved arcuate portion 15c, and
As shown in FIG. The handle 15 is configured to allow the handle 15 to swing from side to side with respect to the handle 11.

In addition, at the center of the end of the handle 15, there is no crease 15d, and a chevron-shaped tongue piece 15e that extends without being bent as an extension end of the band-like part 15a is provided protrudingly from the insertion hole 16. The structure is such that it is easy to insert the engaging portion 15b into the connector, and it is difficult to remove the engaging portion 15b. The entire handle 15 does not necessarily have to be formed into a band shape, and the gripping portion at the center in the longitudinal direction may be narrow or have a circular cross section.

<Effects of the invention> As a result of the handle mounting structure of the present invention being constructed as described above, the box body 11 does not have an engaging protrusion protruding from the peripheral surface, and can quickly and easily attach a separately prepared handle as necessary. In addition to being able to be attached to and removed from the box, even if the handle is tilted with respect to the vertical line due to carrying it with other luggage, etc., the box body can be stably maintained approximately horizontally, for example. This produces effects such as preventing problems such as deformation and damage of cakes, Japanese sweets, etc. Furthermore, the handle can be manufactured by simply processing both ends of a tape-shaped paperboard or the like, and can be supplied at low cost.
