Description

The present invention relates to a box carton with sanitary paper. More specifically, in a box carton in which an outlet is formed on the top surface of a hexahedron paper box and a plurality of sets of folded sanitary paper such as tissue paper are housed inside the box, Further, the present invention relates to a box carton in which a paper outlet is provided on the side of the box, and the box carton can be smoothly taken out not only horizontally but also vertically depending on the usage environment.
The term “side surface” as used herein refers not only to the “long side surface” surrounded by the ridge in the length direction and the ridge in the height direction, but also in the ridge in the width direction and the ridge in the height direction. It is also used to include the enclosed “short side surface (sometimes referred to as end face or toe face)”.

  Box cartons containing tissue paper are widely used at home and at work. Such a box carton is generally provided with a take-out opening in which a transparent resin film with a slit formed in the center is attached to the upper surface of a hexahedron box in order to take out tissue paper. The tissue papers inside the carton are usually stacked and stored so that each pair of tissue papers is folded into a rectangle and the set can be continuously removed from the box. When the tissue paper stored in the box is pulled out and used, the tissue paper is continuously taken out one by one from the outlet on the upper surface of the box to which the transparent resin film is attached.

However, when such a box carton containing tissue paper is used on a desk in a workplace, for example, it occupies a large area on the desk. However, this tissue paper carton has an outlet only on the top surface of the box, so it is not possible to place objects on the top surface, and tissue paper is placed in the space between books or files arranged on a shelf. Cannot be used with a carton. Also, when the carton is placed at a high place, it is difficult to take out the paper. Further, when the paper outlet is turned sideways, there is a problem that when the remaining amount of paper in the box decreases, the stack of papers collapses and the paper in the box cannot be taken out smoothly.
Thus, the conventional box carton has restrictions on the place and space to be placed.

From the above problems, as shown in Patent Documents 1 to 5, for example, techniques for providing paper outlets not only on the top surface of the box but also on the side surfaces have been proposed. That is, Patent Documents 1 and 2 show a technique in which a paper outlet is formed on the long side and the short side of the box, and in particular, what is shown in Patent Document 2 is the lower side of the outlet. However, a substantially T-shaped inclined outlet is provided so as to reach near the bottom of the box so that the paper remaining on the bottom of the box can be smoothly taken out to the end. Furthermore, in what is shown in Patent Document 3, a plurality of outlets are provided on the front and rear sides of the box, and the box can be installed vertically in a gap such as a book or a file. And a technique for attaching a paper outlet to a wall in any direction. And patent document 4 is disclosing the technique which provided continuously the cut line which forms a paper take-out in the box upper surface and the side surface.
Further, the side surface outlet disclosed in Patent Document 5 is provided with a rectangular cut piece on the side surface, and the rectangular cut piece is configured to be opened and closed by a single-opening flap having a lower side as a hinge. When taking out, it aims at preventing the taken-out paper from drooping downward by bending a one-sided flap outward at a right angle.

Japanese Utility Model Publication No. 62-127983 Utility Model Registration No. 2586017 JP 7-187261 A Japanese Utility Model Publication No. 51-47733 Registered Utility Model No. 3045100

However, the box carton as described above has the following problems.
That is, in the case where the paper outlet is formed on the long side or the short side of the box as in Patent Documents 1 to 4, there is no cover for closing the outlet on the side outlet. It was easy to get in and there were hygiene problems.
In Patent Document 5, a horizontally long single opening flap having a lower part as a hinge is provided on a part of a side surface so that a side outlet can be opened and closed. The single opening flap constituting the outlet The hinge part is difficult to move and requires force to open and close, and is easy to tear. In addition, the side take-out port has a problem that it is difficult to continuously take out the paper to be taken out as compared with the upper side take-out port.
As described above, many conventional box cartons with tissue paper are used in which a resin film having a slit is attached to the back surface of the outlet. However, the above-mentioned conventional type box not only increases the manufacturing cost because the number of steps for applying the resin film is increased, but also has to be separated by separating the resin film after use because of waste treatment and recycling treatment. It was troublesome for the user. In view of this, a box carton has been developed that eliminates the need for attaching a resin film provided at the outlet, reduces manufacturing costs, and eliminates waste separation. The present inventor also proposed, for example, as Japanese Patent Application Laid-Open No. 2004-315084 is doing.

  The present invention has been made in view of the problems of the prior art, and the main object of the present invention is to provide a paper outlet in the side of the box as well as the top of the box in a box carton containing sanitary paper. The paper box in the box can be taken out no matter how the box carton is placed, and the shape of the outlet can be used to prevent foreign matter from entering the box without using a resin film. It is to provide a carton that has good usability.

In order to solve the above problems, the present invention proposes the following means. That is, the first of the present invention is a sanitary paper carton in which an outlet is formed on the upper surface of the box and a plurality of sets of folded sanitary paper are housed therein.
At least one of the front, rear, left and right side surfaces of the box is formed with an outlet surrounded by a ridge line formed by the side surface and the top surface of the box and a cut line whose end is in contact with the ridge line. The exit is configured to be openable and closable by a single-opening type flap having the ridge line as a hinge, and further, a protrusion for taking out sanitary paper at both right and left ends of the opening formed when the side outlet is opened. The sanitary paper carton is characterized in that sanitary paper end holding grooves are formed in the upper and lower portions of the guide projection.

  According to a second aspect of the present invention, the lower side portion of the side surface outlet is formed in a shape in which the central portion of the outlet is constricted by an arcuate protrusion that protrudes toward the ridgeline. The sanitary paper carton described in 1.

  According to a third aspect of the present invention, there is provided the sanitary paper carton according to the first or second invention, wherein a push-up piece for pushing up the stored sanitary paper is formed by a substantially arc-shaped cut line on the lower surface of the box. is there.

  A fourth aspect of the present invention is the sanitary paper carton according to any one of the first to third aspects, wherein a resin film is not disposed on the back surface of the upper surface outlet and the side surface outlet.

  By the way, the term “cut line” in the present invention means a line that is easily cut off during use, and is formed as a perforation composed of a cut line and a connecting part. The interval between the cuts may be uniform or non-uniform. The perforations may be single or double perforations, and the double perforations may have an inner perforation and an outer perforation arranged in a staggered manner. Furthermore, an opening cutting line in which a cut called a “zipper” in the packaging industry is bent into a bowl shape may be used.

  The carton of the present invention forms a sanitary paper outlet on not only the top surface of the box but also any of the four front, back, left, and right sides of the box. Use with objects placed on the top surface of the box, insert into small gaps such as car door pockets, dashboards, office shelves, etc., further raise the box, attach to the side of the desk or wall Or can be used in high places. In this way, the sanitary paper in the box can be taken out from any outlet of the box no matter how it is used or placed, so it can be used in limited and limited installation environments. Occupying area can be reduced.

  The carton of the present invention forms, on at least one of the front, back, left and right side surfaces of the box, an outlet surrounded by a ridge line formed by the side surface and the upper surface of the box and a cut line in contact with the ridge line, The side outlet is configured to be openable and closable by a single-opening flap with the ridge portion as a hinge. Therefore, the side outlet is closed by a single-opening flap without attaching a resin film, Intrusion of foreign matter can be prevented. Since the single-sided flap forming the side outlet opens and closes with the ridgeline of the box as a hinge, the hinge is easy to bend and is not easily damaged.

  Further, the carton of the present invention is provided with sanitary paper take-out guide protrusions at opposite left and right ends of the opening window formed when the side outlet is opened, and the guide protrusions above and below the guide protrusions. Since the end holding grooves for sanitary paper are formed in the part, the guide protrusions provided at the left and right ends guide the drawn sanitary paper and hold the end provided at the upper and lower parts of the guide protrusions. The groove holds the end of the sanitary paper that is drawn out so that it does not fall into the box. Further, since the sanitary paper can be sandwiched between the flap end and the lower side of the window, the sanitary paper can be easily pulled out because the sanitary paper can be held at the outlet for the next use opportunity.

  Furthermore, since the push-up piece for pushing up the sanitary paper in the box is formed by a substantially arc-shaped cut line on the lower surface of the box, even if a space is created in the box when taking out the sanitary paper, the user can By pushing the push-up piece inward, it is possible to prevent the sanitary paper bundle from slipping down and maintain the ease of drawing out the sanitary paper.

A preferred form for carrying out the present invention is a box carton for storing tissue paper used in ordinary homes and workplaces. In addition to such tissue paper, the present invention is also suitable for use in a carton for storing arbitrary sanitary paper such as paper towels.
The term “tissue paper” is often used to refer to general disposable paper such as facial paper and toilet paper, but in a narrow sense, it usually has a dry crepe and is mainly used for facial wipes. It may be limited to tissue paper. In addition, “paper towels” are papers that are mainly made of pulp fiber as a substitute for towels and towels. Of these, papers that are mainly used in kitchens are called kitchen papers (Paper and Pulp Technology Handbook). , 5th edition, see page 459, published January 30, 1992, edited and published by the Pulp and Paper Technology Association). In the present invention, the term sanitary paper is used as a general term for these disposable papers.

  The carton of the present invention is manufactured mainly from paper materials such as cardboard made of wood pulp, waste paper, etc., and usually has an outlet for taking out sanitary paper at the center of the box upper surface. In the conventional carton, a resin film (in many cases, a polyethylene film) with a slit in the center is attached to the top outlet, and tissue paper is continuously fed from the inside of the box one pair at a time. Can be taken out automatically. However, what is shown in the embodiment of the present invention is a so-called filmless carton in which a resin film covering the outlet is not attached.

  Next, an embodiment of the present invention will be described with reference to the drawings, but the present invention is not limited to this embodiment.

  FIG. 1 shows an embodiment of the present invention and is a perspective view of an unopened carton. FIG. 2 is a development view of the carton of FIG. FIG. 3 shows a state in the middle of opening the upper outlet. As will be described in detail later, the carton of this embodiment is such that a tissue paper outlet is also formed on the side of the box. Moreover, (I)-(V) of FIG. 4 is explanatory drawing which shows the state which takes out a tissue paper by opening a taking-out port formed in the box side surface by putting a carton vertically.

First, the carton blank of this embodiment is demonstrated based on the expanded view of FIG. In the figure, reference numerals 1 and 2 are upper and lower plates having a wide rectangular shape, and 3 and 4 are side plates forming left and right side surfaces (long side surfaces) having a narrow rectangular shape. These are alternately connected via a broken line. Reference numeral 5 denotes a joining piece connected to one side edge of the lower surface plate 2. The upper surface plate 1 and the lower surface plate 2 and the side surface plates 3 and 4 can be assembled into a rectangular tube shape by the joining piece 5.
Reference numerals 6 and 7 are an upper surface side outer flap and a lower surface side outer flap connected to the upper surface plate 1 and the lower surface plate 2, and both end edges, and 8 and 9 are inner flaps connected to both end edges of the side surface plates 3 and 4. . When the carton is assembled by the machine, the outer flaps 6 and 7 are folded on the outer surfaces of the inner flaps 8 and 9 to seal the opening surfaces (face surfaces) of the main body. A cut line 14 is formed on the tip end side of the wire, and a joining margin 10 is connected to the outside of the cut line 14. The front end portions of the outer flaps 6 and 7 are overlapped and bonded to each other through the joint allowance 10. The length of the upper surface side outer flap 6 is set slightly larger than half the box height, and the length of the lower surface side outer flap 7 is also set slightly larger than half the box height, and the lower surface side outer flap is also set. The joint margin 10 connected to the tip of the joint 7 is formed with a pair of notch steps 11a and 11b at both ends thereof, so that the joint margin is shaped like a tongue. The width of the tongue-shaped joint allowance 10 is larger than the distance between the front edges of the opposing inner flaps 8 and 9 when the inner surfaces of the upper and lower outer flaps 6 and 7 are bonded to the outer surfaces of the left and right inner flaps, respectively. Is formed. With this configuration, the overlapping portions of the upper and lower outer flaps 6 and 7 and the left and right inner flaps 8 and 9 can be joined to close the end walls (face surfaces) at both ends in the longitudinal direction of the box.

  A cut line 14 for facilitating disassembly after use is formed on the boundary between the lower outer flap 7 and the tongue-shaped joint margin 10 connected to the tip. Further, an arc-shaped dissection cut line 12 a starting from a connecting broken line between the lower surface side outer flap 7 and the lower surface plate 2 is formed on the lower surface plate 2. Furthermore, two parallel lines extending from the intersection of the connecting bent line and the arcuate cut line 12a to the cut line 14 formed on the boundary between the lower outer flap 7 and the joint 10 connected to the tip thereof. Cut lines 13a and 13b are formed. Note that the arc of the arc-shaped cut line 12a may be an elliptical arc. Further, it may be a polygonal shape such as a corner, but it is preferably a circular arc having no corners in consideration of ease of manufacturing and safety in use. The diameter of the arc here is 10 to 35 mm, preferably about 20 mm, considering that the user pushes the finger.

Next, the take-out port provided on the upper surface of the box and the tissue paper push-up device provided on the lower surface of the box will be described.
The tissue paper outlet 20 shown in FIG. 2 is formed in a ribbon shape elongated in the longitudinal direction at the center of the top plate 1. The outlet 20 has two perforated opening cut lines 21 with a predetermined interval in the longitudinal direction of the upper surface plate, and wave-shaped end cuts connecting the both ends of the cut line 21 respectively. It is surrounded by the lead wire 22. In addition, hinge portions are formed on both sides of the outlet 20 by curved broken lines 23 that extend in the longitudinal direction of the box and slightly swell toward the outside of the box. The opening end edge of the outlet 20 formed by being surrounded by the cut line 21 and the end cut line 22 and the horizontally long first flap portion 24 are opposed to each other by the curved broken line 23. A pair is formed on the long side so as to protrude to the center. In addition, a curved broken line 25 bulging outward is disposed outside the wavy end cut line 22, and the second tongue-shaped second line surrounded by the end cut line 22 and the bent line 25. A flap portion 26 is formed.

  The take-out port 20 shown in the figure has a narrower shape toward the center, and the entire incision line has a continuous and smooth curved shape. The corrugated curve portion at both ends of the take-out port and the curve at the edge of the first flap portion. The unit can take out sanitary paper such as tissue paper taken out from the carton while being sandwiched between the first flaps 24, and can prevent the sanitary paper from falling into the carton. In particular, in the case of tissue paper stored in a folded state, the take-out direction of the tissue paper taken out at the time of use changes alternately, but as described above, the outlet end is formed by a continuous smooth curve. Therefore, the tissue paper can move smoothly between the first flaps 24, 24, and tearing and catching when pulled out can be prevented.

  On the other hand, a push-up piece 29 surrounded by a connecting fold line between the joining piece 5 and the lower face plate 2 and an arc-shaped cut line 28 is formed at a position near the joining piece 5 of the lower face plate 2. When the remaining amount of tissue paper in the box decreases, the push-up piece 29 can bend the push-up piece 29 inside the box at an arbitrary angle to push up the tissue paper in the box so that it can be easily taken out from the take-out port. be able to. Note that the push-up piece 29 shown in FIG. 2 has a radius of 30 to 50 mm, preferably about 40 mm, as an example, and is formed by a semicircular cut line that ends at the connecting fold line between the joining piece 5 and the bottom plate 2. Although it is formed, it is not necessary to be a complete semicircular cut line as in the case of the cut line 12a, and it may be a polygon.

  Next, the tissue paper outlet provided on the side surface of the box will be described with reference to the carton blank of FIG. 2. When the carton is placed vertically on one side plate 4, the outlet 31 is formed. In other words, the side plate 4 between the upper surface plate 1 and the lower surface plate of the box is formed with an outlet 31 surrounded by a boundary line with the upper surface of the box, that is, a ridge line and a cut line 30 in contact with the ridge line when the carton is assembled. is doing. The side surface outlet 31 is approximately half the size of the top surface outlet 20 and is configured to be openable and closable by a single-opening flap having the ridge line portion as a hinge 32. Sanitary paper take-out guide projections 33a and 33b are provided at both left and right ends of the opening formed when the side outlet is opened, and the sanitary paper is provided above and below the guide projection. End holding grooves 34 and 35 are formed. By forming the lower side portion of the side surface outlet so as to form an arc shape projecting toward the ridgeline, the side surface outlet is formed in a constricted central portion.

An example of a method for taking out the paper from the side take-out port will be described with reference to FIG. First, the carton is placed vertically from the state (I) as shown in (II). Next, after pushing the lower side portion of the side surface outlet 31 with a finger as shown in (III), the ridge line formed between the side surface of the box and the upper surface of the box, and the cut line whose end portion is in contact with the ridge line, The part surrounded by is lifted upward in a single-opening manner as shown in (IV) with the ridge line part as a hinge. Next, the flap of the one-sided opening is opened, and the paper is taken out from the outlet as shown in (V). That is, when the sanitary sheets stacked in the box are sequentially drawn out from the opening formed when the outlet is opened, either of the end holding grooves 34 and 35 provided on the upper and lower portions of the guide protrusions 33a and 33b is determined. The end of the sanitary paper is held so that it does not fall into the box. Since the outlet 31 has a shape formed by a smooth curve with the central portion constricted, when the sanitary paper is taken out, the outlet 31 can be smoothly pulled out from the central portion of the outlet, and the central portion of the outlet is further constricted. By narrowing, the sanitary paper does not fall into the box during long periods of use, even if the resin film having a slit is not used for the outlet, and is held at the outlet for the next use. The
Further, since the take-out port 31 can be closed with a single-open flap, entry of foreign matter such as dust and dirt into the box can be prevented.

  Next, another embodiment of the present invention will be briefly described. The take-out port 31 in FIG. 1 is formed in a shape in which the lower side of the take-out port protrudes upward and the center is constricted, but for example, it can be formed so that both upper and lower sides are parallel like a trapezoid. It is. In the above embodiment, the outlet 31 is provided on one side plate 4, but may be provided on the other side plate 3, or may be provided on both the left and right side plates 3, 4. Further, although not shown, it can be formed on the upper surface side outer flap 6.

  Next, a modified example of the push-up device will be briefly described. In FIG. 5, a pair of linear broken lines 41 a and 41 b is provided at the center of the lower surface plate 2, and arc-shaped cut lines 42 a and 42 b are provided so as to connect both ends of the linear bent lines. Paper lifting pieces 40a and 40b are provided. Further, four push-up pieces 50a to 50d each having a ridge line formed by the side face plate 4 and the lower face plate 2 and a ridge line formed by the joining piece 5 and the lower face plate 2 as hinges are used as the one set of push-up pieces 40a, This is an example in which 40b is provided near the four corners of the bottom plate 2. Since these push-up pieces 40a, 40b and 50a, 50b, 50c, 50d can all be easily separated from the lower surface plate 2 via an arc-shaped cut line, when bent at an appropriate angle inside the carton, The tissue paper inside the box can be pushed up by the folded pieces that are bent respectively.

It is a perspective view which shows one embodiment of this invention and shows an unopened carton. FIG. 2 is a development view of the carton of FIG. It is a perspective view which shows the state which opens the extraction opening provided in the upper surface board of the carton. It is a perspective view which shows the state which opens the taking-out opening provided in the side plate of the carton of this invention, and takes out tissue paper. It is the partial explanatory view which showed the modification of the raising apparatus provided in the lower surface board of a carton.
