Description

[0001]
[Industrial application fields]
The present invention relates to a tissue carton that contains tissue paper, and more particularly to a tissue carton that can be easily folded after use.
[0002]
[Prior art]
The tissue carton that accommodates the folded tissue paper has a box shape for accommodating and taking out the tissue paper. However, when it is discarded after use, it is bulky if it is in the shape of a box, so that it is crushed and folded before being discarded.
[0003]
However, this tissue carton has a relatively simple structure so that it can be easily manufactured. However, the tissue carton is formed so as not to be crushed during transportation. I can't do it.
[0004]
Therefore, for example, in Japanese Utility Model Laid-Open No. 60-190679, as shown in FIG. 7, a cutting machine wire 33 for connecting the end face piece connecting edge ends 32, 32 is formed on the bottom face portion 31, In order to weaken the connecting stamped edges 36 and 37 so that the part 34, the end face flap 35 and the back side face part (not shown), and the end face flap (not shown) connected thereto can be easily separated, for example, end face connection A tissue carton in which half-cut lines are formed on the back surfaces of the ruled edges 36 and 37 is disclosed. This tissue carton can be folded after use by severing the sewing machine wire 33 and the end face connecting stamped edges 36, 37 and then pushing it down in the width direction of the tissue carton.
[0005]
[Problems to be solved by the invention]
However, in the tissue carton disclosed in the above publication, after the sewing machine wire 33 is cut off, the end face flaps 36 and 37 must be cut off before the end face flaps are cut off. In particular, detaching the end face connection stamped edges 36 and 37 is troublesome because the end face flaps are separated from both side surfaces. Further, in manufacturing the tissue carton, means for weakening the end face connecting stamped edges 36, 37, for example, a half-cut line is formed on the back side thereof, and thus a manufacturing process corresponding to that is required. It was.
[0006]
Furthermore, since the end face articulated stamped edges are weakened, the vertical strength is inferior. For this reason, during transportation, a load may be applied from above, or the edge in the height direction may hit an object, which may break before use. In this case, the value as a product is remarkably impaired, and there is a problem that dust is mixed from the broken portion.
[0007]
In order to solve this problem, the present applicant has disclosed a tissue carton in which a weakening means such as a perforation for separation is not formed on an end face connecting stamped edge in Japanese Utility Model Application No. 62-177458. However, even the tissue carton according to the present invention does not eliminate the trouble of having to separate the end face-connected stamped rim when folding, that is, the side part and the end face flap.
[0008]
Therefore, an object of the present invention is to provide a tissue carton that can be folded after use without being separated from the side surface portion and the end surface flap, is easy to manufacture, and does not break during transportation.
[0009]
[Means for Solving the Problems]
The foldable tissue carton of the present invention that has solved the above problems has end face flaps connected to each side face and folded inward, and extends to the upper surface connected to the bottom face and folded inside on the outside of these end face flaps. A bottom surface side end piece having a height not connected to a top surface and a top surface side end piece having a height that does not reach the bottom surface, and the bottom face side end piece and the top face end piece are bonded to the end face flaps, In the tissue carton in which the bottom surface side end surface piece and the top surface side end surface piece are bonded together,
Pushing in the form of a bulging line connecting the two points with respect to the bottom surface or top surface starting from two spaced points on the connection edge between the bottom surface side end surface piece and the bottom surface or on the connection edge between the top surface side end surface piece and the top surface Forming a perforation for forming an incision perforation from each of the starting points to each side of the bottom face side end face piece or the top face side end face piece,
The end portion of the incision perforation is located at a position that does not cover the bonded portion of the upper surface side end surface piece and the bottom surface side end surface piece, and the bottom surface side end surface piece generated when cut along the incision perforation or the The uncut portion of the upper surface side end face piece is not bonded to each end face flap,
It is characterized by this.
[0010]
In this case, it is desirable that the incision perforation is formed in a C-shape symmetrically about a center line in the height direction of the end face as a symmetry axis. In addition, it is desirable that an angle of formation of the perforation for incision with respect to a connecting edge between the bottom face side end face piece and the bottom face or a connecting edge between the top face side end face piece and the top face is 5 to 25 °.
[0011]
[Action]
In the present invention, for example, an incision perforation that connects a point on each side of the bottom surface side end surface piece and a point on a connecting edge between the bottom surface side end surface piece and the bottom surface to the bottom surface side end surface piece is preferably the bottom surface. It is formed in a U-shape symmetrically about the center line in the height direction of the side end face piece, and starting from the end points of the two incision perforations on the connecting edge between the bottom end face piece and the bottom face For example, a pressing perforation having a bulging line shape such as an arc shape is formed on the bottom surface.
[0012]
For this reason, the tissue carton according to the present invention presses the pushing perforation provided adjacent to the connecting edge between the bottom face side end piece and the bottom face with a finger, as described in detail in a later embodiment. Thus, it can be surely pushed through and can be cut along the incision perforation by pushing open as it is. If the incision perforation is cut off, the bottom end piece and the top end piece are pushed and spread together, and the sticking part to the end face flap is peeled off. After that, the end face flap is unfolded and the whole box is folded. Thus, in this tissue carton, the end face portion can be easily opened after use, and it is not necessary to cut off the end face flap when folding, so that it can be easily folded with a small force. In addition, since it is not necessary to form weakened parts such as perforations in the height direction in the assembled state, the manufacturing process can be reduced correspondingly, and breakage during transportation due to the formation of weakened parts may occur. Nor.

【Example】
Embodiments of the present invention will be specifically described below with reference to the drawings.
FIG. 1 is a perspective view of an assembled state of a tissue carton according to the present invention, and FIG. 2 is a plan view showing a developed state thereof. The central portion in the unfolded state is configured as a bottom surface 1, a side surface 2, a top surface 3, and a side surface 4, and a sticking flap 5 connected to the width direction side edge of the bottom surface 1 is stuck to the width direction side edge portion of the side surface 4. Can be assembled into a box shape. On the side edges in the longitudinal direction of the bottom surface 1, side surface 2, top surface 3, and side surface 4 are bottom surface side end surface pieces 11, 11, end surface flaps 12, 12, top surface side end surface pieces 13, 13, and end surface flaps 14, 14. It is connected. In the assembled state, the end surface portion on one side of the tissue carton is formed by bonding the end surface flaps 12, 14, the bottom surface side end surface piece 11, and the top surface side end surface piece 13. In the assembled state of the end surface portion, the end surface flaps 12 and 14 are folded in the innermost side, and the bottom surface side end surface piece 11 is folded on the outer side and adhered to the end surface flaps 12 and 14. And the upper surface side end surface piece 13 is folded in the outermost side, and is affixed on the end surface flaps 12 and 14 and the bottom surface side end surface piece 11. In this assembled state, the top surface side end piece 13 has a height that does not reach the bottom surface 1, and the bottom surface side end surface piece 11 does not reach the top surface 3. Further, the other side surface portion of the tissue carton has the same configuration.
[0014]
Further, the bottom end face piece 11, preferably as an axis in the height direction center line C of the bottom surface side end face piece 11 in the assembled state symmetrical manner, and a point on the side edge 11a, a bottom end face piece 11 Two incision perforations 11A and 11A that connect points on the connecting edge 1a with the bottom surface 1 are formed. An arc-shaped pushing perforation 1A is formed on the bottom surface 1 starting from the end points of the incision perforations 11A, 11A on the connecting edge 1a (hereinafter, the incision perforation 11A and the pushing perforation 11A). The eye 1A may be collectively referred to as a “folding perforation”).
[0015]
Further, a perforation 20A for forming a tissue paper outlet is formed at the center position of the top surface 3, and the tissue paper is pushed up at the center position of the bottom surface 1 when the remaining amount of tissue paper is reduced. A perforation 20B for forming a locking piece that facilitates removal is formed.
[0016]
Next, a folding method after using the tissue carton according to the present invention will be described. First, when the assembled tissue carton shown in FIG. 1 is folded, as shown in FIG. 3, for example, a portion surrounded by pushing perforations 1A, 1A and connecting edges 1a, 1a on both sides of the bottom surface 1 in the longitudinal direction ( (Hereinafter referred to as auxiliary pieces) 1b and 1b are pressed with the thumbs of both hands. Then, the pushing perforations 1A, 1A are torn and the thumb enters the tissue carton.
[0017]
From this state, when the bottom surface side end surface pieces 11 and 11 are spread outward in the tissue carton longitudinal direction, as shown in FIG. 4, the incision perforations 11A and 11A formed on the bottom surface side end surface pieces 11 and 11 are formed. The bottom surface 1 and the bottom surface side end surface pieces 11 and 11 are separated from each other, and are further expanded toward the outer side in the longitudinal direction of the tissue carton, whereby the end surface flaps 12, 12, 14, and 14 on the bottom surface side end surface pieces 11 and 11 are separated. The sticking part is peeled off. Moreover, since the bottom face side end face pieces 11 and 11 and the upper face side end face pieces 13 and 13 are stuck, the upper face side end face pieces 13 and 13 stuck to the bottom face side end face pieces 11 and 11 are also end faces. The flaps 12, 12, 14, and 14 are peeled off.
[0018]
Then, as shown in FIG. 5, after the bottom face side end face pieces 11, 11 and the top face side end face pieces 13, 13 are in a substantially horizontal state, the end face flaps 12, 12, 14, 14 are developed, Tilt the main body part in the direction indicated by the arrow in FIG. 5 and fold the tissue carton.
[0019]
As described above, in the present embodiment, the case where the folding perforation is formed on the bottom surface and the bottom side end face piece has been described, but the folding perforation may be formed on the top face and the top side end face piece.
[0020]
However, when the folding perforation is formed on the upper surface and the upper surface end piece, if the bottom surface end surface piece is folded more inside than the upper surface end surface piece in the assembled state, the upper surface side end surface piece and the bottom surface side When the end face piece is peeled off from the end face flap, the bottom face side end face piece is likely to be peeled off from the upper face side end face piece. If the bottom end piece is peeled off from the top end piece and the bottom end piece is stuck to the end flap, it is difficult to open the end flap. Therefore, when the upper surface side end surface piece is stuck outside the bottom surface side end surface piece in the assembled state, it is desirable to form folding perforations on the bottom surface and the bottom surface side end surface piece. On the contrary, when the bottom face side end face piece is stuck outside the top face side end face piece, it is naturally desirable to form the folding perforation on the top face and the top face side end face piece.
[0021]
Further, a desirable shape of the folding perforation will be described in more detail with reference to FIG. First, although the perforation for pushing formed on the bottom surface (upper surface), this can be a perforated line having an appropriate bulging line formed on the bottom surface (upper surface) starting from the connecting edge. In the above embodiment, the arc shape is used. However, the arc shape is not necessarily required, and may be a flat elliptical arc shape. Alternatively, for example, a shape such as a rectangle or a polygon may be used. However, in order to be easily separated by inserting a finger, and further, a perforation may be easily formed. For this, it is desirable to have a shape having no corners as a whole, that is, a shape such as a circular arc or an elliptical arc.
[0022]
On the other hand, in the present invention, in order to fold the tissue carton, it is assumed that the auxiliary piece 1b is first broken and the thumb is inserted into the tissue carton so that the person who folds the tissue carton can easily insert the thumb. The starting perforation 1A and the width L of the starting point are preferably 15 mm or more. On the other hand, if the width L, that is, the shape of the auxiliary piece 1b is too large, when the finger is inserted into the tissue carton, the resistance increases as the cutting extension increases and the force is dispersed. Therefore, since a large amount of force is required for the incision, the width L of the auxiliary piece 1b is preferably 35 mm or less. The most preferable width L is 25 mm.
[0023]
On the other hand, from the viewpoint of the incision perforation 11A formed on the bottom surface side end face piece 11, is a 11A, easily cut and allocation of force when cutting is made to be equal in each direction, for these incisions perforations 11A, 11A is preferably preferably formed symmetrically shaped height-direction center line C of the bottom surface side end face piece 11 (see FIG. 1) as an axis. However, it does not have to be strictly symmetrical. In addition, when it is formed so as to cover the bonded portion of the bottom surface side end surface piece 11 and the top surface side end surface piece 13, it is difficult to separate, so that it is formed only on the bottom surface side end surface piece 11 or the top surface side end surface piece 13. It is desirable to do. Furthermore, the angle θ formed by the connecting edge 1a and the incision perforation 11A is too small. However, if the angle θ is too small, the incision perforation 11A is difficult to separate in relation to the direction of the force. bottom-side end face piece Broken remainder 11b shown in 4, 11b and bonding area between the end face flaps 12,14 is increased, the obstacle disconnecting these switching Re rest 11b, and 11b from the end face flaps 12, 14 Become. In view of these points, it is desirable to set the angle θ within a range of 5 ° to 25 °. The most preferable angle in this range is 14 °.
[0024]
Further, wherein at each bottom surface side end face piece 11 and the upper end face piece 13 is attached to the end face flaps 12, 14 when folded, uncut portions 11b, 11b is attached to the end face flaps 12,14 5, when the tissue carton is opened until the state shown in FIG. 5 is reached, it is necessary to peel off the bottom-side end face pieces 11b and 11b from the end face flaps 12 and 14, which increases the labor for folding. For this reason, the portions corresponding to the bottom-side end face pieces 11b and 11b can be prevented from sticking to the end face flaps 12 and 14.
[0025]
In general, in order to prevent dust and the like from being mixed into the tissue carton, the bottom surface side end surface piece 11 and the top surface side end surface piece 13 are attached to the end surface flaps 12 and 14, but in the present invention, they are attached. If the attachment force is too large, the bottom surface side end surface piece 11 and the top surface side end surface piece 13 may be difficult to peel off from the end surface flaps 12 and 14 during folding.
[0026]
【The invention's effect】
As is clear from the above description, the tissue carton according to the present invention can be easily folded with a small force after use. Further, it is not necessary to separate the side surface portion and the end surface flap portion when folding. Further, since it is not necessary to form the weakened portion in the end face flap portion, the manufacturing process is reduced, and since the weakened portion is not formed in the height direction, it is not broken during transportation.
