Description

The present invention relates to a carton containing sanitary paper such as tissue paper, and in particular, after use, the resin film pasted around the outlet can be easily peeled off and recycled as it is for used paper for paper recycling. Sanitary paper carton.
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.

In general, a carton containing tissue paper is stored in a substantially rectangular parallelepiped paper box, with the tissue paper being folded up alternately so that one set can be continuously taken out from the box, usually as a set of two sheets. . In many cases, cartons containing tissue paper are packaged in units of five boxes and displayed and sold at stores such as mass retailers and convenience stores. Each box which is film-wrapped has an outlet for taking out tissue paper on the upper surface.
When the outlet (opening) is opened, a resin film such as polyethylene film is attached to the inner surface of the outlet, and this resin film prevents external dust from entering from the outlet, and the tissue in the box The paper is hygienically protected. In addition, a slit is provided in the central portion of the resin film so that dust cannot pass through, and the tissue paper as the contents is drawn out through the slit. The bundle of tissue paper inside the carton is folded by a so-called pop-up method so that when one set of tissue paper is pulled out from the slit, the next set of tissue paper is pulled out from the inside of the box to the position held by the slit. It is stored.
As described above, the resin film adhered to the inner surface of the outlet of the box protects the contents against external dust and foreign matters by reducing the opening area of the outlet, and simultaneously takes out the tissue paper to the outside. In this case, the so-called pop-up tissue paper is prevented from sinking into the box due to friction at a slit provided in the resin film, and the tissue paper is held in a predetermined position (see Patent Documents 1 and 2).

  However, when the paper box is discarded after use, if the resin film is affixed to the inner surface of the take-out port, the paper film must be crushed as it is and the resin film is not peeled off. Since it cannot be recycled as used paper, it is necessary to peel off the resin film, dispose it after separating it, and there is a problem that the user has extra trouble and lacks in recyclability. Also, when incinerated as paper trash, harmful gases and the like are discharged, so it is difficult to incinerate from the viewpoint of protecting the global environment.

By the way, the applicants have proposed paper boxes that can be easily dismantled after use and crushed into a flat shape for easy disposal of paper boxes that store tissue paper or the like (see Patent Documents 3 to 4). ).
However, even in the paper boxes of Patent Documents 3 to 4 that can be easily crushed, it is troublesome to put a hand into the box from the side and peel off the resin film on the back side. May injure the person's finger carelessly. Also, since the resin film is transparent and not easily noticeable, users such as those with poor eyesight and elderly people cannot easily see the transparent film affixed to the inner surface of the outlet, and the film itself is difficult to peel off. There is a problem that the resin film is discarded as it is without being peeled off.

Next, the present invention will be described in more detail based on embodiments of the invention.
The present invention is a substantially rectangular parallelepiped carton for storing sanitary paper such as tissue paper and kitchen paper, and has a sanitary paper outlet on at least one of the upper and lower surfaces of the box.
Sanitary paper stored in the carton of the present invention includes tissue paper, dust paper, paper towels (including kitchen towels, kitchen sheets, and paper used mainly in kitchens), toilet paper (however, rolls) Except), disposable paper such as Watting (paper cotton), etc. (see Paper Pulp Technology Handbook 5th edition, edited and published by Paper Pulp Technology Association). In the present invention, the term sanitary paper is used as a general term for these disposable papers. In general, the phrase “tissue paper” is often used to refer to general disposable paper such as facial paper and toilet paper. In the narrow sense, it is called facial paper and decorative paper. It is a sanitary paper with water absorption. In addition, a paper towel is a paper manufactured using pulp fiber as a main raw material as a substitute for towels and towels, and among these, paper used mainly in a kitchen is referred to as kitchen paper.

The carton of the present invention is a paper box mainly made of paper materials such as cardboard made of wood pulp, waste paper, etc., and is a box that mainly stores sanitary paper such as tissue paper and paper towels. More specifically, this is a sanitary paper carton in which a resin film having a slit is attached to the inner surface of the box to cover the outlet.
Hereinafter, although the specific content of this invention is demonstrated based on the Example shown in a figure, this invention is not limited to this example.

FIG. 1 is a perspective view of a carton of the present invention, FIG. 2 is a developed view showing a carton blank of the present invention, and FIG. 3 is a perspective view of a state in which the carton is flattened.
As shown in FIGS. 1-3, the carton of this invention forms the carton blank which stamped the required unfolding shape by using cardboard as a material like the conventional product, and engraved the fold line and the cut line, and this blank is the fold line. It is assembled into a rectangular parallelepiped and used. The carton has a sanitary paper outlet 10 on the top surface of the box. In the figure, reference numerals 1 and 2 indicate rectangular upper and lower plates facing in the vertical direction when assembled in a box shape, and reference numerals 3 and 4 also indicate a pair of horizontal surfaces facing in the horizontal direction when assembled. It is a rectangular side plate, and is formed symmetrically across the top plate 1. Reference numeral 5 denotes a glue piece connected to one side edge of the lower surface plate 2. Reference numerals 6 and 7 are end face plates connected to both end edges of the upper surface plate 1 and the lower surface plate 2, and reference numerals 8 and 9 are inner flaps connected to both end edges of the side plate 3 or 4. When the end face plates 6 and 7 are assembled in a box shape, the end faces of the end face plates 6 and 7 are overlapped with each other when the both end faces of the cylindrical box body are sealed on the inner flap 8 or 9. It is formed in a length that can be fixed together.

At the tip of one end face plate 7, a margin portion that overlaps with the other end face plate 6 is formed by a perforated cut line 14, and a bent line 16 is formed at the center of the bottom face plate 2 as shown in FIG. 2. When the trapezoidal or inverted trapezoidal perforation lines 17 and 18 are formed in different directions from each other, when the remaining amount of sanitary paper in the box decreases, each perforation is formed from the outside of the box. The sewing machine is separated along the cut lines 17 and 18 so that the bottom is raised, and the sanitary paper is pushed up toward the top plate so that it can be easily taken out.
After all the sanitary paper is used up, the box constructed in this manner is opened by pushing the arc-shaped perforation cut line 15 provided in the end face plate 7 with a finger and inserting the fingertip into this opening. The perforation line 14 is cut off and the upper and lower end plates 6 and 7 and the inner flaps 8 and 9 are opened to the outside, and the entire box is crushed flat as shown in FIG. Can be dismantled.

Next, a method for removing the resin film f attached to the inner surface of the outlet 10 from the used box will be described.
FIG. 4 is a top view of the carton of the present invention showing the state before opening the outlet, and FIG. 5 is a rear view similar to FIG. 4, where the resin film f attached to the surface having the outlet is joined. A region (glue surface) g and a perforation line 19 provided at an outer position surrounding the region (glue surface) g are shown. The resin film f attached to the inner surface of the outlet 10 is formed so as to be cut from the upper surface plate 1 by the perforated cut line 19. In this embodiment, the opening shape formed by cutting the top plate 1 is a substantially rectangular shape, but is not necessarily limited to such a shape, such as an elliptical shape, a rhombus, or a polygonal shape, Needless to say, various opening shapes are possible.

The cut line that forms the cutout portion surrounding the joint region (glue surface) g of the outlet 10 and the resin film f is a cut line 19 of the perforation. This cut line is as shown in FIG. Although it may be a zipper or not shown, it may be formed as a double perforation composed of an inner perforation and an outer perforation, and the inner perforation and the outer perforation are arranged in a staggered manner. Also good. Of course, this perforation does not need to be linear as shown in the figure, and may be formed into a wave shape by a wave blade, and this perforation is formed with a finer blade than a normal blade called a micro blade. Can be made.
In addition, as shown in FIG. 6, it is preferable to provide the finger pushing part 22 by providing the finger pushing part formation cut line 20 and the broken line 21 inside the perforation cut line 19. When the inside of the finger pressing portion forming cut line 20 is pressed with a finger, a knob portion for cutting the top plate 1 is formed. The finger pressing portion forming cutting line 20 is formed by connecting a cutting edge and may be, for example, a semicircular shape or a square shape, but a semicircular shape is preferable.

FIG. 7 is a back view showing another example of the top plate of the carton showing the state before opening the take-out port, and in this example, the joining region of the resin film to be attached to the inner surface of the surface having the take-out port (The hatched portion) By coloring g, the resin film was made noticeable.
As a coloring method, in the resin film adhesion step, a colored paste may be used to spray the surface to which the resin film is to be joined, but the carton side margin (base) surface is colored by means such as color printing. Then, when a transparent resin film is affixed, it becomes conspicuous at the position where the transparent resin film is affixed. Therefore, even users with poor eyes and elderly people can easily perform the work of peeling off the resin film after the box is disassembled.
In addition, by applying colored glue or achromatic glue in a predetermined pattern to the region where the resin film is to be joined, the resin film can be made more conspicuous from others.
When no colored paste is used, it is possible to make the resin film more noticeable by making the resin film itself a colored film or a film with a pattern. The peeling work can be easily performed.
Of course, a perforated cut line 19 is provided at an outer position surrounding the bonding region (glue surface) g of the resin film f, and the resin film f is cut along the perforated cut line 19 as in the above-described embodiment. It is also possible to form it so that it can be cut off from the top plate 1.

  In order to make the bonding region and the resin film conspicuous in the entire circumference surrounding the bonding region of the resin film affixed to the inner surface or in one or several places thereof, as illustrated in FIG. 7 or FIG. It can be printed (marked). In addition, a notice such as “Please remove the film when putting it into garbage” may be printed instead of the above-mentioned discrimination mark.

Next, other examples will be described. 9 to 12 are examples in which a detection window 30 on which sanitary paper can be visually recognized is provided on at least one side of the outlet 10, and a resin film is provided inside the detection window 30 in the same manner as the outlet 10. This is an example in which foreign substances such as dust do not enter from the outside through the detection window (the figure shows an example in which detection windows are provided on both sides of the outlet).
Although this window pasted resin film may be provided separately from the resin film stuck inside the surface having the outlet, the resin film stuck inside the surface having the outlet is shown in FIG. As shown in FIG. 12, it is preferable to serve also as the resin film f stuck inside the said detection window. The bonding region (glue surface) of the resin film is indicated by the symbol g as in FIG. Colored glue may be used to spray the bonding area of the resin film, but if the carton side glue (base) surface is colored by means such as color printing, the film itself may be a transparent film. Good. Furthermore, it is also possible to pattern-apply colored glue or achromatic glue on the bonding area of the resin film, or to print and display the discrimination marks 23 to 25 (marking) as illustrated in FIG. 7 or FIG. In the same way as in the previous example, it is possible to print a precautionary note such as “Please remove the film when putting it in garbage” instead of the discrimination mark.
Although not shown in the drawings, the resin film f is provided with a perforated cut line 19 at the outer position surrounding the bonding region (glue surface) g of the resin film f pasted to the outlet, as in the above embodiment. Can also be formed so as to be cut off from the top plate 1 by the perforation line 19.

Further, in the illustrated example, the perforated cut line 19 is provided at a position inside the ridge line of the surface having the sanitary paper outlet (meaning a boundary line with the long side surface or the short side surface of the carton). You may make it cut out the whole surface which provided the cut line on the said ridgeline, and affixed the resin film.
Further, a part of the cut line may be formed so as to reach the long side surface or the short side surface beyond the ridge line. In this case, if one of the cut lines provided on the ridgeline (boundary with the long side surface or the short side surface) is a crease line (ruled line), the surface on which the resin film is pasted is opened in a single-opening manner. It becomes easy to peel off the resin film. This example is also one of the embodiments of the present invention.

As described above, the user of the carton of the present invention can easily peel off at least the resin film attached to the inner surface of the box.
Therefore, when the box is disassembled after use, the box from which the film has been peeled can be recycled as a valuable paper resource as a raw material for recycling, so that the workability during paper recycling can be improved.
