Description

The present invention relates to a sanitary paper-filled carton. More specifically, an outlet (opening) for taking out sanitary paper is provided on at least the upper surface of the carton, and it is not necessary to attach a window pasting film covering the outlet on the inner surface of the outlet. Opening is made so that no dust is taken out when opened, and sanitary paper falls into the box during use so that it can be removed smoothly and continuously, and the opening can be closed during use. The present invention relates to a structure of an outlet for a carton containing sanitary paper that prevents dust and the like from entering the box from being contaminated.
In the present invention, “sanitary paper” refers to tissue paper (what is called facial paper, decorative paper, etc.), dust paper, paper towels (kitchen paper, etc.), toilet paper (excluding rolls), and Watting (paper cotton). ) And other disposable papers.

A carton containing tissue paper is usually provided with an outlet for taking out the tissue paper on one side of a substantially rectangular box (usually the upper surface of the box). Remove a part of the box along the eyes and open the outlet (opening). A resin film such as a polyethylene film that covers the outlet is usually attached to the inner surface of the outlet (see, for example, Patent Document 1).
A slit is formed at the center of the resin film, and the tissue paper inside the box is drawn out through the slit of the film. This tissue paper is usually folded and stored as a set of two sheets so that each set can be continuously taken out of the box. When one set of tissue paper is pulled out from the slit of the resin film The next set of tissue paper is folded by a so-called pop-up method so as to be pulled out from the inside of the box to a position held by the slit.
The resin film adhered to the inner surface of the outlet prevents the so-called pop-up tissue paper from falling into the box due to friction between the slits of the film when pulling out the tissue paper. Plays a role that can be drawn to. In addition, by providing a resin film, external dust and foreign matter are prevented from entering the box.

However, in the case of Patent Document 1, the resin film is exposed by cutting and removing a part of the box surface along the perforation that forms the opening from the unopened state, and tissue paper is exposed from the slit of the exposed film. Therefore, when part of the box is removed along the perforation to remove the thick paper in the opening, strip-shaped paper dust having a length and width corresponding to the opening is generated. In addition, since the resin film is affixed to the inside of the opening, it is necessary to manufacture, process, and affix the resin film at the time of manufacture, which increases the manufacturing cost, and the used box after taking out the tissue paper In the case of discarding, it is necessary to remove the resin film from the viewpoint of environmental protection, and the user is forced to take extra time.
Recently, packaging manufacturers are strongly required to reduce the amount of packaging waste and collect used packaging. In the case of tissue paper storage boxes, it has begun to be requested to collect and recycle the boxes as used paper after use. However, when collecting as used paper, the resin film is different from paper, which is an obstacle to collection and recycling.

Therefore, recently, a carton containing tissue paper that does not attach a resin film to the opening has been attracting attention. However, tissue paper cartons that do not have a resin film attached to the opening make it easy for the tissue paper to fall into the box during use due to the wide opening, and dust and so on can get into the box. This causes inconvenience such as dirty tissue paper. Therefore, it is possible to reduce the size of the opening or hold the tissue in a special shape so that the tissue paper does not fall into the box. However, there is a drawback that the tissue paper is easily caught and difficult to take out. . (For example, see Patent Documents 5 to 7).
In addition, there has been proposed a box containing tissue paper provided with a flap portion that can be opened in a double-spread shape at the tissue paper outlet (see, for example, Patent Documents 2 to 4).

The present applicant also discloses a “filmless carton” according to Non-Patent Document 1. This box has a structure in which an opening formed by a zipper-type band-shaped cut-out portion and a pair of flaps for holding paper on both front and rear sides of the opening. This “film-less carton” is formed by arc-shaped curves at the left and right ends of the cut-off part that forms the box opening. The purpose is to prevent the paper from being caught and torn and to continuously and smoothly take out the tissue paper one by one in a pop-up manner without dropping the tissue paper into the box during use. However, when the box is opened, a band-shaped cut portion that forms an opening is generated as dust. In addition, there is a disadvantage that dust is likely to enter the box from the belt-shaped opening.
Japanese Utility Model Publication No.41-6464 Japanese Utility Model Publication No. 57-167080 JP-A-9-150871 Japanese Utility Model Publication No. 4-80878 Japanese Utility Model Publication No. 6-72883 Japanese Patent Laid-Open No. 9-30573 Japanese Utility Model Publication No. 63-144492 Oji Paper's public relations magazine “Sound of the Forest”, Oji Paper's Public Relations Office, published on June 20, 2003, summer issue, pages 25-26

An object of the present invention is to eliminate the need to cut and remove a part of the box surface when opening a carton, and to prevent the generation of paper dust. The structure prevents the entry of dust and foreign matter from the outside, and the tissue paper clamping function at the opening and its removal performance are eliminated, eliminating the need for a resin film to be attached to the back of the opening. It is intended to reduce costs and improve recyclability after use.
In addition, consumers tend to demand a high-grade feeling for sanitary paper such as tissue paper, and one of the ideas to meet these demands is to add a scent to tissue paper. Accordingly, another object of the present invention is to provide a carton that can easily impart a fragrance that is pleasant to the user to the sanitary paper when the sanitary paper is pulled out of the box.
Still another object of the present invention is to provide a filmless carton that can suppress the sound produced when the paper box and tissue paper come into contact with each other when the tissue paper is taken out.

In order to solve the above problems, the present invention includes the following means.
That is, the first of the present invention is a substantially rectangular parallelepiped carton that contains sanitary paper and has no resin film attached to the inside of the sanitary paper outlet,
A cut line for forming an outlet is formed at a position offset to one of the long sides of the carton upper surface with respect to the longitudinal center line C of the carton upper surface, and on the long side of the carton on both sides of the cut line. A hinge portion constituted by a curved broken line that bulges outward along the line is disposed, and a cut line for forming the outlet and a curved broken line that constitutes the hinge portion have respective ends. Are connected by a curved cut line at the portion, surrounded by a cut line for forming the outlet, a curved broken line constituting the hinge portion, and a curved cut line connecting them The flap portion is provided with two large and small flap portions that can be opened and closed, and a folding line is provided on the large flap portion in a position parallel to the cut line so that the flap portion can be partially bent in two steps. Even after opening the carton, the two Tsu is outlet structure of sanitary paper carton, characterized in that to be able to seal the outlet up by up unit.

  According to a second aspect of the present invention, a second hinge portion configured by a broken line along the short side of the carton is disposed outside both ends of the cut line for forming the outlet, and the second hinge portion is The exit structure for a sanitary paper-filled carton according to the first invention, wherein a second flap (movable piece) is formed surrounded by a broken line and a curved cut line at the end. It is.

  According to a third aspect of the present invention, there is provided a sanitary paper-containing carton outlet according to the first or second aspect, wherein a paint containing a fragrance is printed on at least one back surface of the flap portion. Structure.

  According to a fourth aspect of the present invention, there is provided the sanitary paper-containing carton outlet structure according to the first or second aspect, wherein an aromatic member is attached to at least one back surface of the flap portion. .

  According to a fifth aspect of the present invention, a lubricant for reducing the frictional force between the sanitary paper and the outlet rear surface is attached to at least one rear surface of the flap portion. The exit structure of the sanitary paper-filled carton described in 1.

  The carton with sanitary paper of the present invention can be opened by being cut off by pressing the cutting line with a finger from an unused state, and a part of the box surface is not cut and excised, so that it does not generate dust when opened. There is.

  Moreover, since the necessity of sticking the resin film to the back surface of the opening is eliminated, not only the film material cost is saved, but the film manufacturing / processing and sticking work becomes unnecessary. Further, when the used box is discarded by eliminating the film, the trouble of removing the film and separating the carton and the film is eliminated, so that the empty box can be easily recovered and regenerated, thereby improving efficiency.

  In addition, the first configuration of the present invention allows the flap portion to be bent in two steps, allows a large outlet when opened, eliminates the difficulty in removing tissue paper during use, First, even if the tissue falls into the box, it is easy to insert the finger into the box and pull out the tissue paper.

Furthermore, when the cartons according to the present invention are used for a long time with the tissue paper being dispensed, the tissue paper can be sandwiched between two flap portions that can be opened and closed, so that the box can be used during a long period of use. Tissue paper does not fall inside, and it is easily pinched for the next use opportunity.
Furthermore, the carton of the present invention has a structure that prevents dust and foreign matter from entering the box during use since the paper outlet can be completely closed by the flap portion even after the carton is opened.

Furthermore, when taking out the sanitary paper according to the third configuration or the fourth configuration, a pleasant scent can be imparted to the user on the sanitary paper. When the sanitary paper is not taken out, the paper outlet can be sealed by the flap portion, so that the fragrance can be prevented from being released out of the box. Therefore, it can be expected that the sanitary paper is given a high-class feeling by the aroma imparted from the carton, and the user is given various effects such as a refreshing effect and a relaxing effect by the scent of the sanitary paper.
In addition, the fifth configuration makes it possible to smoothly take out sanitary paper and suppress the generation of sound during removal.

As described above, the present invention is a substantially rectangular parallelepiped carton for storing sanitary paper such as tissue paper and kitchen paper, and has an outlet on at least the upper surface.
The term “tissue paper” is a general term for all disposable paper such as facial paper and toilet paper, but in a narrow sense, it has a dry crepe and is limited to facial tissue paper used mainly for facial wipes. It may be pointed out. The “paper towel” is a paper manufactured using pulp fiber as a main raw material as a substitute for a towel and a towel. Among these, a paper used mainly in a kitchen is called a kitchen paper.

The carton in the present invention is a storage box mainly made of paper materials such as cardboard made of wood pulp, waste paper, etc., and is a storage box mainly storing sanitary paper such as tissue paper and paper towels. More specifically, a window pasting film having an outlet (opening) for taking out sanitary paper on the upper and lower surfaces (usually the upper surface) of the paper box and having a slit covering the outlet on the inner surface of the box. There is a feature in the structure of the outlet of the so-called filmless tissue carton that is not provided.
Next, the present invention will be described based on an embodiment shown in the drawings.

1 to 3 show an example of an embodiment of the present invention. In the figure, the same reference numerals as those in FIG. 1 denote the same parts, and the basic structure of the box is conventional (tissue paper). Carton).
FIG. 1 is a perspective view showing a carton of the present invention, and FIG. 2 is a perspective view showing a state in the middle of pulling out tissue paper Tp from the opening by opening the tissue paper extraction opening on the top surface of the carton in FIG. It is. FIG. 3 is a perspective view showing an example in which tissue paper is sandwiched between two flap portions that can close the tissue paper outlet.

  The carton of the present invention is similar to the conventional tissue paper carton, in which a cardboard blank is punched into a required developed shape to form a carton blank with a fold line or a cut line, and the blank is bent along the fold line to form a rectangular parallelepiped shape. Used to assemble. FIG. 1 shows the state of the upper surface of the carton before opening, and the cut line 3 for forming the outlet is formed at a position offset to one of the long sides of the upper surface of the carton from the longitudinal center line C of the upper surface of the carton. Has been. In FIG. 1, reference numeral 1 denotes a carton containing sanitary paper, and 2 denotes the upper surface of the carton.

The cut line 3 for forming the outlet is formed by a wide-sewing machine line, but may be a breaking line for opening in which a cut called a “zipper” is bent in a bowl shape for easy breaking. (Refer to page 281 of the well-known and commonly used techniques in the packaging industry, issued by the Patent Office on December 20, 1978), or a long linear cut (slit), or may be provided in a waveform by a wave blade. Both are examples of the cut line of the present invention. Further, this cut line may be formed by a finer cut than a normal perforation by a micro blade.
In addition, the cut line may be a single straight line extending in the longitudinal center line C direction on the upper surface of the carton, but is constituted by a plurality of cut lines formed substantially in parallel at a predetermined interval. But you can. When there are a plurality of cut lines, for example, two cut lines may be arranged as a double line to form a set of cut lines. Also, two types of perforations with different lengths of cuts can be arranged in a staggered manner.

On both sides of the cut line 3 for forming the take-out opening, there are formed hinge portions formed by curved broken lines 4a and 4b that swell along the long side of the upper surface and slightly bulge toward the outside of the box. Further, cut lines 5 and 5 formed by corrugated curves are connected to both ends of the cut line 3 for forming the outlet and both ends of the curved bent lines 4a and 4b constituting the hinge portion. ing.
And, surrounded by the cut line 3 for forming the outlet, the curved broken lines 4a, 4b constituting the hinge portion, and the curved cut lines 5, 5 connecting them, the outlet is Two large and small flap portions 6a and 6b that can be opened and closed are formed. On the large flap portion 6a, a fold line 7 is provided at a position parallel to the cut line 3 for forming the outlet, and the free end 8 side of the flap 6a is formed so as to be bent in two steps.
A second hinge part constituted by a fold line 9 along the short side of the carton is disposed outside both ends of the cut line 3 for forming the outlet, and a fold line 9 constituting the second hinge part; A second flap (movable piece) 10 is formed surrounded by the curved cut line 5 at the end.
Reference numeral 11 denotes a small substantially arc-shaped cut line 11, which avoids breakage of the ends of the curved broken lines 4a and 4b constituting the hinge portion, and does not get caught on the hinge portion when the tissue paper is pulled out. It is provided so that it can be pulled out smoothly.

  In the above-described configuration, first, the cut line 3 for forming the outlet is pressed and released with a finger, and the fingertip is further slid from the free end side 8 side of the large flap 6a to the back surface so that the flap 6a can be The carton 1 is opened by pulling upward by the curved broken line 4a. At this time, it is not necessary to break and remove a part of the flap as in the prior art. Then, a finger is inserted through the opening formed and the first tissue paper Tp is pulled out from the box as shown in FIG. According to the above configuration, the opening can be made large, and the difficulty of taking out the tissue paper at the time of use is eliminated, and even if the tissue falls into the box, the finger is inserted into the box. It is easy to pull out tissue paper.

  The bent lines 4a and 4b constituting the hinge portions of the left and right flap portions 6a and 6b are curved to bulge toward the long side of the upper surface of the carton (to the outside of the box). When opened diagonally upward, a closing tendency force (force to return to the state before bending) works. Further, since the movable piece 10 is formed surrounded by the broken line 9 constituting the second hinge part and the curved cut line 5 at the end, the tissue paper Tp taken out from the box is as shown in FIG. Between the flaps 6a and 6b and the movable piece 10, and can be easily pulled out while preventing the paper from falling into the carton.

  The carton of the present invention can be resealed when dispensing tissue paper, and in this case, the outlet can be completely closed by the flap portions 6a, 6b. The structure makes it difficult for foreign objects to enter. In addition, tissue paper can be sandwiched between two flaps that can be opened and closed (see Fig. 3), so the tissue paper will not fall into the box during long periods of use, and the next use It can be easily picked and held for the occasion.

Next, a modified example of the present invention will be described.
FIG. 4 shows an example in which a coating material 12 containing a fragrance is printed on at least one back surface of the flap portions 6a and 6b (this is referred to as fragrance printing in this specification). When the sanitary paper is pulled out, the sanitary paper is rubbed against the portion on which the fragrance is printed, so that the microcapsules are destroyed and the fragrance is applied to the sanitary paper. This perfume printing can be easily carried out by printing means such as screen printing, offset printing, stamp pressing, etc., which are well-known methods for carton blanks during the manufacture and processing of cartons that contain tissue paper. Here, an example of perfume printing will be briefly described. In the fragrance printing, the fragrance is enclosed in a microcapsule of several μm, and the fragrance ink combined with the ink component is printed. This microcapsule has the effect of breaking the capsule when necessary and releasing the scent, the function of slowly releasing the microcapsule from the small pores over a long period of time, the so-called release properties, The fragrance printed with perfume ink can be stored for a long period of time if the pressure is not applied, such as rubbing the microcapsules in the ink and the fragrance in the ink diverges when the printing surface is rubbed or pressure is applied. it can. The scent to be encapsulated in the microcapsule can be selected from several tens of varieties. Depending on the scent to be encapsulated, various effects such as a relaxing effect, a refreshing effect, and an insect repellent can be expected.
Moreover, a perfume ink can also be printed by the said means on the inner surface of any flap part visible from the outside when opened. And when a flap part is opened, while a character and a pattern of printing attract consumer's interest and raise an advertising effect, a fragrance gives a sense of quality and can stimulate demand.
In addition, it can replace with the said fragrance | flavor printing and can also affix an aromatic member to the at least one back surface part of the said flap part. As the fragrance member, a sheet in which perfume oil, which is the source of fragrance, is adsorbed on a resin such as urethane may be adhered to the flap portion.
In any of the above cases, when the tissue paper is pulled out (see FIG. 4), the tissue paper touches the portion on which the fragrance is printed or the fragrance member, and the fragrance is added to the tissue paper.

Although not shown, it is possible to attach a lubricant for reducing the frictional force between the sanitary paper and the back surface of the outlet on at least one back surface of the flap portion. Examples of lubricants include waxes that are esters of fatty acids and monohydric or dihydric alcohols, higher fatty acids such as palmitic acid and stearic acid, amides with monohydric higher alcohols, or solid but non-crystalline with a low melting point. Polyethylene, polypropylene, ethylene / propylene copolymer, silicon resin, fluorine resin, or the like is preferable.
If such a configuration is adopted, the pull-out resistance of the tissue paper can be greatly reduced, the tissue paper can be taken out smoothly, and the tissue paper can be pulled out continuously without being cut to the end. When taking out the tissue paper to the outside, it is possible to suppress the sound produced by the contact between the paper box and the tissue paper.

FIG. 1 is a perspective view showing an example of a carton according to the present invention. FIG. 2 is a perspective view showing a state in the middle of opening the tissue paper extraction opening on the upper surface of the carton of FIG. 1 and pulling out the tissue paper Tp from the opening.
