Description

  The present invention relates to a packaging box with a handle.

When displaying and carrying boxes with large items such as shampoo bottles and glass bottles at the storefront, they are difficult to handle because they are difficult to grasp. There was a problem such as having to.
As a means for solving such a problem, there is a method of attaching a handle belt to a box by fusing, bonding, fitting or the like (see Patent Documents 1 to 3), but requires a separate part and a separate process. For this reason, there are disadvantages that the processing and work process become complicated, and that material costs, processing costs, and the like are incurred.

  On the other hand, there is a method of forming a handle by using a part of the box (see Patent Documents 4 and 5), but since the signboard portion cannot be formed, the appearance is remarkably impaired, and the handle is still formed. In this state, the boxes cannot be stacked stably, and when they are put in a transport box, a space is created in the upper part of the box, so that a safe and inexpensive transport form cannot be taken.

JP 2009-96513 A Japanese Patent No. 3787777 Utility Model Registration No. 3025410 JP 2001-206349 A JP 2009-23672 A

  The present invention makes it possible to form a handle that is easy to hold and can be held with peace of mind, suitable for placing large and heavy items, etc., and even after forming the handle, the boxes can be stacked or an extra space can be left in the shipping container. It is an object of the present invention to provide a packaging box with a handle that can be stored without emptying.

The present inventor has solved the above-mentioned problem by making a part of the left and right upper side flaps longer and allowing them to fit with each other to form a handle.
That is, according to the present invention, a front plate 1, a back plate 2, left and right side plates 3, 4 and a lower cover plate 5 are provided, and an upper cover plate 11 and an upper insertion piece 12 are sequentially extended on the upper edge of the front plate 1. The upper side flaps 31 and 41 are extended at the upper edges of the left and right side plates 3 and 4, and both the upper side flaps 31 and 41 are bent at a right angle, and then the upper lid plate 11 is bent at a right angle. Further, in the packaging box that is sealed by bending the upper insertion piece 12 inward at a right angle and inserting it between the back plate 2 and the ends of the left and right upper side flaps 31 and 41, the left and right upper side flaps 31 , 41 are cut in a direction parallel to the back plate 2 to form rear side half-cut upper side flaps 311 and 411 and front side half-cut upper side flaps 312 and 412, and left and right front side half-cut upper side flaps 312 and 412. Near each other The hooks 3H and 4H that can be fitted are provided, and the lengths from the bent portions of the left and right front half cut upper side flaps 312 and 412 are obtained by fitting the hooks 3H and 4H to each other to further play. In addition, the handle is a packaging box with a handle that allows the hook portions 3H and 4H to be fitted to each other to form a handle.

  According to the present invention, it is possible to form a handle that is easy to hold and can be held with peace of mind, which is suitable for putting large and heavy items, etc. without extra materials and costs. It is possible to provide a packaging box with a handle that can be stacked with each other or stored without leaving an extra space in the transport box.

It is a perspective view of one example of a packaging box with a handle of the present invention. It is an expanded view of an example of the packaging box with a handle of FIG. It is explanatory drawing which shows the other example of the fitting type of a handle. It is explanatory drawing which shows the example of the shape of the hook part provided in a back side half cut upper side flap.

Hereinafter, the packaging box with a handle of the present invention will be described with reference to FIGS.
The packaging box with a handle shown in FIG. 1 is assembled from the state of the developed view of FIG. In addition, since the packaging box with a handle of the present invention is supposed to store a relatively heavy product, as shown in FIG. 2, the lower cover plate is formed by combining complicated shapes. However, since the lower lid plate is not a characteristic part of the present invention, detailed drawing is omitted in FIG.

The packaging box A is provided with a front plate 1, a back plate 2, left and right side plates 3, 4 and a lower cover plate 5, and an upper cover plate 11 and an upper insertion piece 12 are sequentially extended on the upper edge of the front plate 1. The signboard portion 21 is extended at the upper edge of the back plate 2, and the upper side flaps 31, 32 are extended at the upper edges of the left and right side plates 3, 4.
Thus, both the upper side flaps 31 and 41 are bent inward at a right angle, then the upper cover plate 11 is bent inward at a right angle, and the upper insertion piece 12 is bent inward at a right angle, so The upper cover plate 11 is locked by being inserted between the end portions of the upper side flaps 31 and 41 to form a packaging box.
The signboard portion 21 is not necessarily provided, but it is preferable to provide the signboard portion 21 because the overall balance and appearance are improved. When provided, the fishing hole 21H is appropriately provided.

However, in the packaging box of the present invention, the left and right upper side flaps 31, 41 are cut in a direction parallel to the back plate 2, and the back side half cut upper side flaps 311, 411 and the front side half cut upper side flaps 312, 412 are Is forming.
The left and right back side half-cut upper side flaps 311 and 411 are bent inward at a right angle so that the upper cover plate 11 is locked.
On the other hand, hook portions 3H and 4H that can be fitted to each other are provided in the vicinity of the front ends of the left and right front half cut upper side flaps 312 and 412 and the lengths from the bent portions of the left and right front half cut upper side flaps 312 and 412 are provided. The handle portions can be formed by fitting the hook portions 3H and 4H together so that the hook portions 3H and 4H can be fitted to each other to have more play.

As the hook portions 3H and 4H, one is a slit and the other is a locking piece, and a form of fitting by inserting the locking piece into the slit is preferable. 1 to 3, for convenience, the slit is indicated as 3H, and the locking piece is indicated as 4H.
As shown in FIGS. 1 to 3, the shape of the slit 3 </ b> H is preferably a shape in which both ends are obliquely bent in the direction of the base of the front side half-cut upper side flap 312, since the locking piece 4 </ b> H can be easily inserted and is not easily detached. .
As shown in FIGS. 1 and 2, the shape of the locking piece 4H is a tongue-like shape whose tip is directed toward the base of the front side half-cut upper side flap 412 and can be easily inserted into the slit 3H. It is relatively easy and easy to remove when taking out.
However, on the contrary, in order to prevent the stored product from being inadvertently taken out, that is, to prevent unauthorized opening, it is preferable to make it harder to come off, and there are various shapes as shown in FIG. The shape and direction can be taken.

That is, the locking piece 4H shown in FIG. 3A has an arrow shape with the tip directed toward the tip of the front side half-cut upper side flap 412. The arrow width is the width including the bent portion of the slit 3H. Since they are substantially the same, it is extremely difficult to remove them from the slit 3H.
The locking piece 4H shown in FIG. 3B has an arrow shape whose tip is directed toward the base portion of the front side half-cut upper side flap 412. However, when it is lowered by a handle, the weight of the contents is reduced. Since the shape is received at the base of the arrow shape, sufficient strength is obtained, and the arrow width is substantially the same as the width including the bent portion of the slit 3H, so it is extremely difficult to remove from the slit 3H.

The locking piece 4H shown in (C) of FIG. 3 has the same arrow shape as that of (A) and (B). However, a slit 4HC is provided at the tip of the arrow and the tip is clamped from the left and right. The arrow width of the arrow shape is narrowed to facilitate insertion into the slit 3H.
In the case of the embodiment shown in FIG. 3C, the arrow width is larger than the width including the bent portion of the slit 3H. When it returns to the arrow width, it is almost impossible to remove it from the slit 3H.
However, providing a slit at the tip of the arrow shape is also applicable to the shapes of (A) and (B).

  As described above, in the case of the mode shown in FIGS. 3A to 3C, it is extremely difficult or almost impossible to remove the locking piece 4H from the slit 3H. . Therefore, easy cutting lines 3P, 4P such as perforations are provided on either one or both of the left and right front half upper side flaps 312, 412 and cut from there to remove the handle and take out the product. It is preferable that the handle can also function to prevent unauthorized opening.

  In the packaging box of the present invention, the left and right upper side flaps 31 and 41 are cut in a direction parallel to the back plate 2 to form the back side half cut upper side flaps 311 and 411 and the front side half cut upper side flaps 312 and 412. However, the ratio of the width W2 of the front side half-cut upper side flaps 312 and 412 to the width W1 of the back side half-cut upper side flaps 311 and 411 locks the upper cover plate 11 to the back side half-cut upper side flaps 311 and 411. It is appropriate that W1: W2 = 1: 4 to 3: 2 to form a handle having a necessary strength with the front side half cut upper side flaps 312 and 412.

  The left and right upper side flaps 31 and 41 are cut in a direction parallel to the back plate 2 and the width (depth) of the left and right rear side half cut upper side flaps 311 and 411 formed thereby is small. Although the box tends to swell laterally from the boundary between the bases of the upper side flaps 311 and 411 and the base of the handle, the movement in the depth direction tends to increase, and further, the box tends to tear from the boundary of the base. As shown in FIGS. 1 and 2, bases 311 </ b> B and 411 </ b> B of the rear side half-cut upper side flaps 311 and 411 and the front side half-cut upper side flaps 312 and 412 are connected to the front side half-cut upper side flaps 312 and 412. Such an inconvenience can be prevented by curving in a circular arc shape.

The length from the bent part (base part) of the side flaps and the left and right back side half-cut upper side flaps 311 and 411 should be half or less of the lateral width of the back plate 2 so that the tips do not overlap each other. As long as it plays the role which locks the board 11, as shown in FIG.1 and 2, it should just be in the range of 20 to 50% of the horizontal width of the backplate 2. As shown in FIG.
However, the back side half cut upper side flaps 311 and 411 are fixed by hook portions in the same manner as the front side half cut upper side flaps 312 and 412, and the length when fixed is equal to the lateral width of the upper lid plate 11, or By being configured to be slightly shorter, the box is prevented from collapsing from the boundary between the base of the back side half-cut upper side flaps 311 and 411 and the base of the handle, and the movement in the depth direction is increased, and the top cover Since the role which locks the board 11 can be played, it is preferable.

The hook portion in this case is a combination of the slit 3I and the locking piece 4I as shown in FIGS. 4A and 4B, or the notches 3J and 4J as shown in FIG. 4C. May be.
Furthermore, as shown in FIG. 4 (B), by providing the slit 3I in the form of rotating about 5 ° to 15 ° in the direction of the back plate 2 (upward in FIG. 4, ie, counterclockwise in FIG. 4), When the back side half-cut upper side flaps 311 and 411 are pulled together in the fitted state, the tips of the back side half-cut top side flaps 311 and 411 slightly approach the back plate 2 in a form that slightly intersects at the fitting part, The locking function by the bases of the side half-cut upper side flaps 311 and 411 can be more reliably achieved, and the above-described bases 311B and 411B are curved in an arc shape on the front side half-cut upper side flaps 312 and 412 side. The effect by this can also be acquired reliably.

  In addition, the base of the back side half-cut upper side flaps 311 and 411 functions as a locking mechanism, so that when the box is assembled, the width is widened so as to contact the back plate 2, but this contributes to the locking mechanism of the base. Since the width is narrowed in the front end direction beyond the portion to be fitted, as described above, the front end of the back side half cut upper side flaps 311 and 411 slightly approaches the back plate 2 so as to cross each other at the fitting part. However, the tips of the back side half cut upper side flaps 311 and 411 do not collide with the back plate 2 and the insertion of the upper insertion piece 12 is not hindered.

The length from the bent part (base part) of the left and right front half upper side flaps 312 and 412 and the position where the hook parts 3H and 4H are provided can form the handle by fitting the hook parts 3H and 4H, In a state where the handle is not pulled up, it is necessary that the left and right front side half cut upper side flaps 312 and 412 have a length and a position that allow play so that they can be flatly overlapped.
That is, the length of the front side half-cut upper side flaps 312 and 412 and the positions of the hook portions 3H and 4H that can form a gap in a state where the handle is formed and the handle is pulled up are set to the positions of the hook portions 3H and 4H. It is preferable that the length of the hook part 4H is such that the hook part does not come off even when the side half cut upper side flaps 312 and 412 are in a state where they overlap with each other.

However, if you increase the gap when you raise the handle too much, you will not be able to play its role if the handle has a function to prevent unauthorized opening, so if you raise the handle up, It is preferable that there is a gap between the handle and the upper lid plate 11 that is 10 mm or more and does not exceed the vertical width (depth) of the upper lid plate 11.
Further, in order for the front side half cut upper side flaps 312 and 412 to function as a handle and overlap with each other flatly, each length is preferably longer than half the width of the back plate 2 and shorter than the entire width. .

Further, as shown in FIGS. 1 and 2, a recess 11C is formed by vacuum forming or the like at a position near the front plate 1 at the center of the upper cover plate 11 and under the formed handle, It can be inserted to make it easier to hold the handle.
The width of the recess 11C is 50% to 80% of the width of the box (25% to 40% from the center of the handle to both sides), and the vertical width (depth) is the same width as the handle to the vertical width of the box (depth). ) And a depth of 5 to 20 mm is preferable. Moreover, it can also have an effect which presses down and fixes a product from the upper part by making it the shape which corresponds to the shape of stored goods.

The material of the packaging box is not particularly limited, and a synthetic resin sheet, paperboard, synthetic paper, a laminated material composed of a synthetic resin sheet and paperboard, synthetic paper, or the like can be used, and these board materials are punched and shaped.
Among these plates, the use of a transparent synthetic resin sheet allows the appearance, pattern, color, etc. of the product to be visible at the time of display, so toiletries such as cosmetics, various care products and travel products, and orals such as toothbrushes It is particularly suitable for storing daily items such as care products and sanitary products such as contact lens cleaning agents.
In addition, after storing goods, when displaying the packaging box A of this invention in the state which locked the upper cover board 11 and also formed the handle, usually the back board 2 is made into the front. Display.

  The material of the synthetic resin sheet is not particularly limited, but biodegradation of thermoplastic resin, for example, polyester such as polyethylene terephthalate and polybutylene terephthalate, polyolefin such as polystyrene, polypropylene and polyethylene, polycarbonate, vinyl chloride, polyvinyl alcohol, and polylactic acid. Preferred are plastics.

The thickness of the plate material varies depending on the material and the like, but can be appropriately determined in consideration of ease of handling and strength. For example, in the case of a synthetic resin sheet, it is preferably 0.1 to 0.5 mm, more preferably 0.2 to 0.4 mm, and in the case of paperboard, it is preferably 0.3 to 1 mm.
When forming the concave portion 11C by shaping a thermoplastic resin sheet, it is appropriate to heat-soften the thermoplastic resin sheet and perform thermoforming by a method such as vacuum forming, pressure forming, or press forming.

  The packaging box with a handle of the present invention is easy to hold and can form a handle that can be held with peace of mind, and even after the handle is formed, the boxes can be stacked or stored without leaving an extra space in the transport box. Therefore, it can be preferably used to put in a large and heavy product.
