Description

The present invention relates to a carton mainly containing sanitary paper such as tissue paper. More specifically, a so-called film which does not require a window-attaching film for covering the inside of the box with an opening (opening) for taking out sanitary paper on at least one of the upper and lower surfaces of the paper box. It relates to the structure of the outlet of the restish carton.
In the present invention, “sanitary paper” refers to tissue paper (what is called facial wipe, decorative paper, etc.), dust paper, paper towel (such as kitchen paper), toilet paper (excluding rolls), watting (paper cotton). ) Is a general term for disposable paper.

A carton storing tissue paper, which is widely used in homes and offices, has a structure in which an outlet for taking out tissue paper is provided on one surface (usually, the upper surface of the box) of a substantially rectangular storage box. The user cuts the cut piece along a substantially elliptical perforated cut line provided on one surface of the box (usually the upper surface of the box), and opens the outlet (opening) in an elongated shape. Usually, a film such as a polyethylene film covering the outlet is attached to the inner surface of the outlet (see Patent Document 1).
A linear slit is provided in the center of the film, and the tissue paper as the content is drawn out through the slit. The tissue paper inside the carton is usually folded and stored alternately as a set of two sheets so that each set can be taken out of the box continuously, and when one set of tissue paper is pulled out from the slit, The next set of tissue paper is folded in a so-called pop-up manner so as to be pulled out from the inside of the box to a position held by the slit.
The film affixed to the inner surface of the box protects the contents against external dust and foreign substances by reducing the opening area of the outlet, and when removing the tissue paper to the outside, the gap between the film slits is reduced. This prevents the so-called pop-up tissue paper from dropping into the inside of the box due to the friction in the box, and plays a role of holding the tissue paper at a predetermined position.

On the other hand, for the purpose of eliminating the material cost of a plastic film such as polyethylene and the step of attaching the film to a box, a so-called “filmless tissue carton” having a structure in which the film is not attached to the inner surface of the outlet has already been proposed. . That is, there is known a tissue paper packaging box in which an opening can be opened like a double door without using a film in an outlet of a boxed tissue paper (for example, see Patent Literature 2, Patent Literature 3, Patent Literature 4). .
Also, in the same `` filmless tissue carton '' as in the previous example, the tissue paper being taken out is elongated in the longitudinal direction of the box, and the longitudinal ends of the outlet formed in a substantially rhombic shape are opened at a specific angle shape. 2. Description of the Related Art There is known a tissue-carton-containing carton that can be held at both ends of a take-out port so that a drop does not occur inside the box (for example, see Patent Document 5).
Further, there is also known a carton in which slits are formed at both end edges of an outlet so as to sandwich tissue paper without limiting the shape of the outlet to a diamond shape (for example, see Patent Document 6).

  On the other hand, there is known a tissue paper box in which tissue paper outlets are provided on two surfaces, an upper surface and a lower surface facing the tissue paper-containing carton, so that tissue paper can be taken out from both surfaces of the carton. (See, for example, Patent Document 7).

In recent years, regarding the disposal of waste, which is one of the environmental issues, the Container Recycling Law, which clarified the responsibility of consumers for separate discharge, collection and collection of local governments, and the recycling of businesses, particularly for container and packaging waste, was established in 1997. It has been fully enforced since then, and the movement toward building a recycling-oriented economic society is accelerating. Under these circumstances, when disposing of used cartons of tissue paper, kitchen paper, and other sanitary paper, there is no need to peel off the plastic film attached to the outlet from the carton itself, or the carton can be collected and recycled as used paper. The need for “filmless tissue cartons” has been increasing due to advantages such as the elimination of the need to separate paper and plastic into paper and the mere crushing of the paper and recycling.

  However, in the aforementioned filmless tissue cartons, in the case of Patent Documents 2 to 6, the shape of the both ends of the outlet is linear or the shape of the end of the flap is angular, so that the tissue paper is externally attached. When taking out the tissue paper, the tissue paper is easily caught on the corners of the take-out opening, etc., and it tears when pulled up, or the tissue paper cannot be taken out smoothly in a pop-up manner. is there.

  The strength of tissue paper is the strength of paper in the direction of pulling out the tissue paper held in the storage box.However, the strength of paper is related to other quality requirements of tissue paper, and it is easy to change it. is not. Further, the size of the tissue paper outlet is large, so that it is difficult to tear. However, if it is too large, it becomes difficult to hold the popped-up tissue paper at a predetermined position of the outlet, and there is a problem that the tissue paper easily falls into the box.

On the other hand, in the carton disclosed in Patent Document 5, the opening angle of both ends in the longitudinal direction of the substantially diamond-shaped outlet is set from 60 degrees to 170 degrees. When the paper is taken out, the paper is caught by the corners and is difficult to be torn or taken out. On the other hand, when the paper exceeds 170 degrees, the gripping function is deteriorated, and there is a problem that the tissue paper easily falls into the box.
Further, in the case of the carton of Patent Document 6, the entrance of the slit is narrow, so that it cannot be said that the tissue is easy to enter, and since the shape of the slit portion is not smooth, it can be said that the tissue is easily caught by the corner.

Not only that, if the outlet is too large, outside dust and other foreign matter can easily enter the box, and when used around the kitchen, mud, dust, or water or There is a problem in that the oil jumps into the box from the outlet, and the contents to be kept clean are easily soiled or wet.
By the way, as shown in Patent Documents 1 to 6, many tissue paper cartons are provided with an outlet for taking out tissue paper on one surface (usually the upper surface) of a substantially rectangular parallelepiped storage box. . Since the tissue paper carton has an outlet for tissue paper only on the upper surface, there is no other use than to place the tissue paper on a tabletop or a floor and remove the tissue from the outlet on the upper surface. For this reason, when the amount of tissue paper stored in the inside of the box decreases, it becomes difficult to remove the lower one. To remove it, the box had to be held with one hand, and a bottom-up mechanism had to be placed on the bottom of the box to lift up the little tissue paper. In addition, when used, the space is blocked up to take up space on the table or floor.

  As an attempt to improve the above-mentioned problem, as disclosed in Patent Document 7, a tissue paper outlet is provided on two surfaces of an upper surface of a carton containing tissue paper and a lower surface opposite to the carton, regardless of how to place the box at the time of use. There has been proposed one capable of taking out tissue paper from two upper and lower surfaces. However, if the amount of tissue paper stored inside the box becomes small, it becomes difficult to hold the tissue paper at the predetermined position of the exit even if the bottom-up mechanism is installed, and it becomes easy for the tissue paper to fall into the box. In some cases, the tissue paper cannot be removed smoothly from the outlet. Furthermore, if the tissue paper box is used standing on its side, the tissue paper bundle inside will be bent by its weight or fall down, so that it will not be possible to pop up the last tissue paper stably. Has occurred.

An object of the present invention is to solve the problem that when tissue paper is taken out, the problem is that the tissue paper is caught by the corners of the opening or the like and becomes difficult to take out, and at the same time, when discarded after using the carton, paper and plastic are removed. The purpose is to provide a filmless carton that can save the trouble of sorting. Further, another object of the present invention is to enable a tissue paper to be taken out one set at a time in a pop-up manner without dropping tissue paper into a box during use, and to be smoothly taken out from the takeout opening. An object of the present invention is to provide a filmless carton having a structure in which dust and foreign matter hardly enter.
Still another object of the present invention is to remove the tissue paper from either of the upper and lower surfaces of the carton so that it can be used without discrimination between the upper and lower surfaces of the carton. A film that can be used in any place, standing upright (vertical placement), can be used in a narrow place, and makes it easy to take out the contents of the tissue paper even when the remaining tissue paper becomes small. It is to provide Leska Ton.

  In order to solve the above problems, the present invention includes the following means. A first aspect of the present invention is a carton containing sanitary paper, which has an elongated outlet in the longitudinal direction of the box on at least one of the upper and lower surfaces of the box, and in which the film is not arranged inside the surface having the outlet.

In the present invention, the “cut line” means a line that is separated at the time of opening, and the “fold line” means a line that is easily bent at the time of opening.

The carton storing the sanitary paper such as the tissue paper and kitchen paper of the present invention has a pair of first flap portions functioning as a door at the time of taking out the paper, even if the film is not disposed on the surface having the take-out opening, in particular, the first flap portion. Since the paper is taken out while being sandwiched between the nip portions formed at both ends of the flap portion, the paper does not drop during the taking out, and the taking out is easy. Further, the paper can be easily taken out one sheet or one set by the action of the sandwiching portion, so that it is possible to prevent the paper from being taken out more than necessary.
Further, since the outlet is surrounded by a curved cut line and a curved broken line, when taking out tissue paper or the like, the tissue paper may be caught by a corner of the opening and torn as in the related art. There is no. In particular, in the case of tissue paper, since the tissue paper is alternately folded and stored, when taken out, the direction in which the tissue paper to be taken out is changed alternately, so that the sandwiching portion at the end of the first flap is also alternately sandwiched. However, since the curved cut line at the end of the first flap and the end cut line at the end of the cut portion have a continuous smooth wave shape, the movement between the sandwiched portions can be smoothly performed. It is excellent in preventing the paper from being torn or caught.
Further, when the opening at the outlet is small and the paper is not taken out, a force acts on the two flaps in the direction to close the outlet, so that dust and foreign matter are hardly penetrated.
Furthermore, since it is not necessary to arrange the film inside the outlet, it is not necessary to separate the paper carton and the film at the time of disposal, and the product is environmentally friendly. Furthermore, elimination of the film not only saves material costs but also shortens the manufacturing process, thereby achieving energy and resource savings.

Next, the present invention will be described in more detail based on embodiments of the present invention.
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 at least on an upper surface. In the present invention, sanitary paper stored in a carton is tissue paper (also referred to as facial wipes, decorative paper, etc.), dust paper, paper towels (kitchen towels, kitchen sheets, paper sheets mainly used in kitchens called empty sheets) ), Toilet paper (except for rolls), watting (paper cotton), and other disposable papers (Paper and Pulp Technical Handbook, 5th edition, page 459, issued January 30, 1992, Edited and published by Japan Society of Pulp and Paper Technology). In the present invention, the term "sanitary paper" is used as a generic term for these disposable papers. In general, the phrase "tissue paper" is often used to refer to general disposable paper such as facial wipes and toilet paper, but in a narrow sense, it usually has dry crepe and is used mainly for facial wiping. It is used only for tissue paper, and the latter is adopted in this specification. "Paper towels" are papers produced using pulp fiber as a main ingredient as a substitute for towels and towels, and among them, those mainly used in kitchens are called kitchen papers.

  The carton according to the present invention is a storage box mainly made of paper material such as cardboard made of wood pulp, waste paper or the like, and is a storage box mainly storing sanitary paper such as tissue paper and paper towel. More specifically, an opening (opening) for taking out sanitary paper is provided on at least one of the upper and lower surfaces (usually the upper surface) of the paper box, and a window-attached film having a slit for covering the opening on the inner surface of the box is provided. There is a feature in the structure of a so-called filmless tissue carton that is not provided.

  In order to form the outlet of the present invention, a cut line extending in the longitudinal direction of the central portion is provided on at least one of the upper and lower surfaces of the box. This cut line may be a linear cut (slit), a perforated cut having a partial connection, or a cut called a “zipper” in the packaging industry bent into a hook shape. Includes a tear line for opening (refer to page 281 of the well-known and commonly used technology of the packaging industry, issued by the Patent Office on December 20, 1978), which is also an example of the score line of the present invention. In addition, this cut line of the present invention may extend in a straight line substantially in the longitudinal direction of a substantially central portion of the outlet, as shown in an example described later, but is generally in the width direction of the outlet. It is constituted by two or two sets of cut lines formed substantially in parallel at a predetermined interval. When two cut lines are provided, a plurality of cut lines, such as two perforations, are arranged as double lines to form one set of cut lines.

  One embodiment of the present invention is constituted by at least two or two sets of perforated cutting lines that are located on at least one of the upper and lower surfaces of the box and extend in the longitudinal direction substantially at the center in the width direction of the box. Has a narrow band-shaped cutout. On both sides of the band-shaped cutout portion, a hinge portion formed by a curved broken line extending in the longitudinal direction of the box and expanding toward the outside of the box is formed. Further, a pair of first flaps in the form of a double door that can be drawn are provided, being surrounded by the cutout and the hinge.

  Both ends in the longitudinal direction of the pair of first flap portions are formed in a smooth curved shape, preferably a circular arc shape, which bulges out of the box by a cut line continuous with the pair of hinge portions. The cut line may be perforated or zippered, but is preferably formed as a continuous cut to make the cut surface smooth. Further, the sanitary paper being taken out from the inside of the box is pinched by the frictional force between the curved opening end formed by the cut line and the end of the first flap portion, so that the sanitary paper enters the inside of the box. Fall can be prevented.

The second embodiment of the present invention is different from the first embodiment in that the opening cut line is one or a pair and there is no band-shaped cutout, but other configurations are the same as those of the first embodiment. It is almost the same as the form. In addition, one set includes a plurality of cut lines, for example, two perforations, which are arranged as double lines to form one set of cut lines.
When taking out the sanitary paper housed in the carton from the take-out opening in the present invention, when one or one set of opening cut lines is used (in the case of the second embodiment), this opening cut line is designated by a finger. When the band-shaped cutout portion is arranged (in the case of the first embodiment), the user cuts the band-shaped cutout portion, puts a finger from the opened portion, and puts the uppermost sanitary paper. , The pair of first flap portions are pulled out according to the force while rising up obliquely upward along a curved fold line bulging out of the box. The angle of inclination is preferably about 15 to 30 degrees. Further, the next sanitary paper following this is pulled out from the opened portion, and also functions to elastically sandwich and hold the sanitary paper between the opposing sides of the pair of first flap portions. Of course, it is also possible to open the pair of first flap portions (doors) by bending the first flap portion obliquely upward with the force of a finger, thereby forming an opening. Is preferably formed by the “finger power” as described above.

  Note that, as described above, the broken line forming the hinge of the pair of first flap portions that can be drawn to the left and right is formed into a curved shape, preferably an arc shape, which bulges toward the long side (outside the box) of the upper surface of the carton. By doing so, a force that tends to close (force to return to the state before bending) acts on the first flap portion when it is opened obliquely upward. For this reason, a force for elastically holding the sanitary paper being taken out between the pair of first flap portions and holding the sanitary paper at a predetermined position in the opening portion acts. Can be prevented from falling. When the sanitary paper is not taken out, the first flap portion serves as a lid of the carton to return to the state before the folding, and functions to prevent the intrusion of external dust and foreign matter. The effect of holding the sanitary paper is large mainly at both ends of the first flap portion, and is small between the opposing sides formed by two or two sets of opening cut lines.

It is preferable that the interval between two or two sets of cut lines constituting the strip-shaped cut portion is about 5 to 20 mm in a narrow portion before opening the outlet. If the interval is too small, it is difficult to cut off the cutout portion. If the interval is too wide, dust and foreign matter easily enter the carton, which is not preferable.
The length of the first flap portion in the longitudinal direction is about 65 to 100% when expressed as a ratio to the length of the stored sanitary paper in the carton long side direction (the length of the sanitary paper). It is preferable that it is 75 to 95%. If this ratio is too small, the hygiene paper will be broken and it will be difficult to take it out. If this ratio is too large, the hygienic paper that is to be held above the outlet will be easily dropped into the box, which is not preferable. For the same reason, the length of the strip-shaped cutout in the longitudinal direction (the minimum dimension at the center) is 50 to 95 when expressed as a ratio to the length of the stored sanitary paper in the carton long-side direction. %, More preferably 65 to 85%.

The carton of the present invention has an outlet at least on the upper surface, but may also have a similar outlet on the lower surface facing the upper surface. When the outlet having the configuration of the present invention is arranged on the two opposing surfaces in this manner, when the remaining sanitary paper is running low, the two holding flaps at the outlet on the lower surface are approximately 90 degrees inside the carton. By folding and pushing up the internal sanitary paper to the upper side, the last one of the sanitary papers can be stably popped up, and the hygienic paper can be easily taken out.
In addition, when a carton having an outlet having the configuration of the present invention disposed on two opposing surfaces is used upright with the side face down, not only can sanitary paper be taken out from both surfaces, but also the first paper can be placed inside the carton. When the flap portion is folded and used, the bundle of sanitary paper inside can be prevented from being bent by its weight or displaced downward, so that the take-out property of the sanitary paper is improved, particularly in a narrow place, for example, in an automobile. It is convenient to use on a dashboard.

  Further, on the inner surface (the inner surface of the box) of the first flap portion, it is possible to print and use a pattern, a character or a pattern which is visible from the outside when opened. For example, if a lottery or the like is printed on the surface, the interest of the consumer can be attracted, the advertising effect can be enhanced, and demand can be stimulated.

Next, the present invention will be further described with reference to the drawings, but the present invention is not limited to this example. 1 to 7 show an example of an embodiment of the present invention, in which parts denoted by the same reference numerals as those in FIG. 1 represent the same parts, and the basic box configuration is a conventional one (tissue paper).

In FIG. 7B, a double line composed of two parallel perforations having different lengths of cut portions of the perforations is configured as a set of cut lines. This is an example in which the cut portions of the perforations are arranged alternately with a phase shift so that the cut portions of the perforations are staggered, and the cut portions of different lengths arranged in a staggered manner as described above. FIG. 9 is a plan view showing an example in which a pair of cut lines formed of parallel perforations having a line are provided on both sides of the band-shaped cutout portion 13.
Further, FIG. 7 (c) is a partially enlarged view of the perforation shown in FIG. 7 (b).

  As shown in FIG. 1, the carton of the present invention forms a carton blank in which a cardboard is punched into a required developed shape and a broken line or a cut line is formed in the same manner as a conventional carton. Assemble and use in a rectangular parallelepiped shape. This carton usually has a tissue paper outlet on the upper surface of the box, but FIG. 1 shows an example in which tissue paper outlets 10a and 10b are provided on two opposing surfaces (upper surface and lower surface) of the carton. . In FIG. 1, reference numerals 1 and 2 denote rectangular upper and lower plates, respectively, which are formed symmetrically. Numerals 3 and 4 denote a pair of rectangular side plates, and numeral 5 denotes a glue margin connected to one side edge of the lower plate. The upper plate 1 and the lower plate 2 are formed wider than the side plates 3 and 4. The tissue paper outlets 10a and 10b are formed symmetrically similarly to the upper surface plate and the lower surface plate. Reference numerals 6 and 7 denote end plates connected to the upper and lower plates 1 and 2 and both end edges. Reference numerals 8 and 9 denote inner flaps connected to both end edges of the side plates 3 and 4. The end plates 6 and 7 are to be folded on the inner flaps 8 and 9 to seal both end surfaces of the cylindrical box body at the time of carton production. The lengths of the end plates 6 and 7 are set such that the ends of the end plates can be overlapped and fixed when sealing both end surfaces of the tubular main body at the time of box making.

Next, the configuration of the tissue paper outlet will be described with reference to an embodiment. The tissue paper outlet shown in FIG. 1 is provided in the center of the upper surface plate 1 and the lower surface plate 2 to be elongated in the longitudinal direction. That is, the outlet has two perforated opening cut lines 11a and 11b extending in the longitudinal direction of the box at the center of each of the face plates and parallel at a predetermined interval. I have. Also, there are end cut lines 12a and 12b connecting both ends of the cut lines 11a and 11b, respectively.
A band-shaped cutout 13 surrounded by the two perforated cutout lines 11a and 11b and end cutout lines 12a and 12b is formed in the longitudinal direction of the central portion of the upper plate 1 and the lower plate 2. Respectively.
On both sides of the band-shaped cutout portion 13, hinge portions formed by curved broken lines 14a and 14b extending in the longitudinal direction of the box and expanding toward the outside of the box are formed. The lines 11a and 11b are connected to both ends of the curved broken lines 14a and 14b constituting the hinge portion by curved cut lines 15a and 15b.

Then, a pair of first flaps surrounded by the opening cut lines 11a and 11b, the curved broken lines 14a and 14b constituting the hinge portion, and the curved cut lines 15a and 15b connecting these. Parts 16, 16 are formed.
Further, the tongue-shaped protrusions surrounded by the end cut lines 12a and 12b at both ends of the cutout 13 and the curved cut lines 15a and 15b are provided at the base of the tongue at the short side of the box. The second flap portion 17 is formed by arranging parallel broken lines 18.
As described above, the curved portions (curved cut lines 15a and 15b, end cut lines 12a and 12b) of the second flap portion and the curved edges (cut lines 15a and 15b) of the carton opening are formed. Has a continuous and smooth corrugated shape, and the corrugated portion of this corrugated shape and the curved portions (curved cut lines 15a and 15b) at the end of the first flap form sanitary paper such as tissue paper taken out of the carton. And can be taken out smoothly, and the paper can be prevented from falling into the carton. In particular, in the case where the tissue paper is folded and stored alternately, as in the case of tissue paper, the take-out direction of the tissue paper to be taken out changes alternately during take-out (see FIG. 3). Although they are interleaved alternately (alternately alternately on the 15a side and 15b side), as described above, the tissue between the interleaved portions is formed by the continuous smooth wave shape formed by the second flap portion and the like. The paper can move smoothly, and it is excellent in preventing the paper from being torn or caught.

  In the figure, the portion where the curved broken lines 14a and 14b constituting the hinge portion of the first flap portion 16 and the curved cut lines 15a and 15b at the end of the first flap portion are connected to each other in the box. It is preferable to form so as to be in contact with a small substantially arcuate cut line 19 curved toward the long side. With such a configuration, it is possible to avoid breakage of the end portions of the curved broken lines 14a and 14b constituting the hinge portion, and to smoothly pull out the tissue paper without being hooked on the hinge portion when the tissue paper is pulled out. Become. This small, substantially arcuate shape may have a radius of curvature of several mm, for example, and may be a curve close to an arc instead of an arc. Also, a circular or oval shape may be punched. An example of a specific shape of this part is shown in FIG. 10, but is not limited to this. (1) of FIG. 10 shows an example in which a part of a circular arc having a radius of 1 mm is close to an elongated circular shape as a whole. FIG. 10 (2) shows an example of an arc having a radius of 1 mm, and FIG. 10 (3) shows an example of an arc having a radius of 2 mm.

  Incidentally, in the case of the carton shown in FIG. 1, the dimension in the longitudinal direction is 242 mm as an example, the dimension in the lateral direction is 116 mm, and the height is 50 mm. The length of the outlet 10 in the longitudinal direction is 200 mm, and the width of the carton in the lateral direction is 60 mm. The interval between the two perforation lines 11a and 11b constituting the cutout portion 13 of the outlet is formed to be 10 mm in the case of FIG. 1, but the cutout portion is easily cut out by inserting a finger. The size is preferably as small as possible, and preferably about 5 to 20 mm. The radius of curvature when the curved broken lines 14a and 14b forming the hinge portion of the outlet are arc-shaped is set to 560 mm as an example, but a force in the closing direction is obtained after opening the first flap portion. Therefore, it is preferable to set the thickness to about 300 to 760 mm. If the radius of curvature is too small, the closing force is too large, and if it is too large, the closing force is too small. Further, the hinge portion may be not an arc but a curve close to an arc, as long as an appropriate closing force can be obtained.

In addition, FIGS. 5, 6, and 7 show examples of the cut line 11 provided in the outlet of the present invention, which are different from FIG. FIG. 5 shows an example in which the perforated line is replaced with a zipper, and FIG. 6 shows an example in which only one perforated line is provided at the center of the outlet, and FIGS. b) is an example in which two sets of cut lines are provided in which perforated cut lines are formed of double lines. In the examples of FIGS. 7A and 7B, a zipper is provided at one end of the band-shaped cutout portion sandwiched between two sets of double lines. Although not shown, the cut line does not need to be linear, and may be provided in a waveform by a wave blade. Further, the cut line may be a finer cut line than a normal perforation called a micro blade, and these are all examples of the cut line of the present invention.
FIG. 7B shows two perforations having cuts of different lengths on both sides of the band-shaped cutout 13 arranged in parallel, and the cuts of each perforation are staggered. The perforations having long cuts are located inside the carton, and the perforations having short cuts are placed outside the carton. When two kinds of perforations having different lengths of the cutout portions are arranged in a staggered manner, when the band-shaped cutout portion is picked and cut with a finger, an uneven cutout is formed along the perforations, so that the appearance is improved. Often, the edges of the band-shaped cutout portions are not fluffed or crumpled and do not form uneven jagged cut surfaces, so that the appearance is good. In addition, when the band-shaped cutout is cut off, it can be easily opened with a small force, so that the band-shaped cutout can be easily opened and the sound at the time of cutting can be reduced. Furthermore, even when the carton of the present invention is manufactured from a multi-layered white paperboard mainly composed of waste paper, the edges of the band-shaped cutout portions can be cut off relatively smoothly and neatly as described above, so that printing and coloring were performed. The upper layer of the surrounding paper can be cut off without being peeled off (peeling of the paper layer can be prevented). Furthermore, a cut line formed of two parallel perforations having cut portions of different lengths in a staggered arrangement on both sides of the band-shaped cut portion 13 is formed by cutting the cut portion of the inner perforation. Since the cut portion of the long perforation is formed short, the edge of the band-shaped cut portion is cut off in an uneven shape when the band-shaped cut portion is cut, so that the appearance of the cut is improved.

In this case, as shown in FIG. 7C, the length d of the long cut portion m is preferably 1 to 6 mm, and the length e of the short cut portion n is 0. It is preferable that the ratio d / e of the length d of the long cut portion of the perforation and the length e of the short cut portion of the perforation is in the range of 1.2 to 12. Is preferred. When the length and the ratio of the cut portions of the two perforations are in this range, the band-shaped cut portion can be cut easily and neatly. When the length of the long cut portion m and the short cut portion n of the perforation are less than 1 mm and less than 0.5 mm, respectively, it becomes difficult to cut the band-shaped cut portion, and the long cut portion m and the short cut portion are reduced. When the length of n exceeds 6 mm and 3 mm, respectively, the strength of the band-shaped cutout decreases, and the band-shaped cutout is easily broken by an impact during transportation or storage. When the ratio d / e is less than 1.2, it becomes difficult to cut the band-shaped cutout cleanly. When the ratio d / e exceeds 12, the strength of the band-shaped cutout decreases, and the impact during transportation or storage is reduced. Thereby, the strip-shaped cutout portion is easily broken.
Further, the interval i between the cut portions m and n of the two perforations is preferably 0.2 to 1 mm. When the interval i between the cut portions m and n of the two perforations is less than 0.2 mm, the strength of the band-shaped cut portion is reduced, and the band-shaped cut portion is easily broken by an impact during transportation or storage, If the length is longer than 1 mm, it becomes difficult to cut the band-shaped cutout portion.
Further, the distance h (the length of the connecting portion) between the adjacent cut portions m in the perforation having the long cut portion m is equal to the length e of the cut portion n having the short cut portion n. The length g (the length of the joint portion) between adjacent cut portions n in a perforation having a short cut portion n is the same length, and the cut portion of the perforation having a long cut portion m It is preferable to arrange the cut portions m and n of the two perforations in a staggered manner by setting the length to about the same as the length d of the m. The length of the insertion portion may be adjusted so as to have a slightly overlapping margin. In a perforation having a long notch m, a distance h (length of a connecting portion) between adjacent notches m is preferably 0.5 to 3 mm, and a perforation having a short notch n. Is preferably 1 to 6 mm between adjacent cut portions n (length of the joint portion).
Further, the width f of the cut portions m and n of each perforation is preferably 0.5 to 3 mm.

  FIG. 9 shows another example different from FIGS. 1, 5, 6, and 7, in which a tab portion bent line 30 is provided in a band-shaped cut portion 13 of a tissue paper outlet to form a tab portion 31. Is a modified example of the carton. Also, in this example, unlike the examples of FIGS. 1 and 5 to 7, the curved cut lines 15a and 15b and the end cut lines 12a and 12b are discontinuous cuts having a connecting portion (connecting portion). It is composed of a wire. The other example in FIG. 1 is an example in which these cut lines are constituted by continuous cut lines. Further, this example (FIG. 9) is different from the example of FIG. 1 in that an outlet is provided only on the top plate. FIG. 10 is an enlarged view showing an example of the configuration of one end of the tissue paper outlet, and shows the shape of a small substantially arcuate cut line connected to the hinge end of the first flap. .

In the carton of the present invention, as shown in FIGS. 2 and 3, when the opening is opened to take out the tissue paper P stored in the box, one opening cut line 11 in the upper opening is provided. In the case of, press and unfold with your finger. When the band-shaped cutout 13 is arranged, one of the left and right second flaps 17 is pressed down from the broken line 18, a finger is inserted under the end of the cutout 13, and the cutout is pinched and cut out. Thereafter, when the uppermost tissue paper is picked up from the opened portion and pulled out upward, the pair of first flap portions 16, 16 are inclined obliquely upward along the curved fold lines 14a, 14b bulging outward. Bend while bending. In this case, as shown in FIG. 9, near the end of the band-shaped cutout portion 13, the pick-up fold line 30 is disposed substantially orthogonal to the opening cutout lines 11 a and 11 b to form the pick-up portion 31. Easy to open and preferable.
Further, the following tissue paper is pulled out from the opened portion, and is between the opposing sides of the pair of first flaps, between the opposing sides of both ends of the first flap and the second flap, and in a box. And is held in a pop-up state by being elastically sandwiched between the opening edges of the opening.
Further, the pair of first flap portions 16, 16 are opened diagonally upward by forming bent lines 14a, 14b serving as hinges into an arc shape bulging outward on the long side of the upper surface of the carton. When closed, a tendency to close (force to return to the state before bending) acts. For this reason, while the tissue paper being removed is elastically sandwiched between the pair of first flap portions and the second flap portion, a force acts to hold the tissue paper at a predetermined position of the opening, and even if the content of the tissue paper is reduced, Prevents tissue paper from falling into the carton. When the tissue paper is not taken out, the first flap portion serves as a lid of the carton in an attempt to return to the state before bending, thereby preventing external dust and foreign matter from entering.

  When the remaining amount of tissue paper in the box decreases, as shown in FIG. 8, the pair of first flap portions provided at the outlet of the lower plate can be used by being bent inward as a bottom-up member. . That is, the two first flap portions 10 in the lower outlet 10b are bent approximately 90 degrees inside the carton, and the tissue paper inside is pushed up to the upper side, whereby the end of the tissue paper is discharged from the upper outlet 10a. Up to one sheet can be stably popped up.

Further, in this embodiment (example of FIG. 1), since the tissue paper outlet is provided on two opposing surfaces (upper surface and lower surface) of the carton, discrimination between the upper and lower surfaces of the carton is eliminated, and the method of placing the carton during use is eliminated. Also, as shown in FIG. 11, both the horizontal and vertical installations can be used, so that they can be used in a narrow place. In addition, since the tissue paper can be taken out from either of the upper and lower surfaces, even when the amount of the stored tissue paper is reduced, the ease of taking out the tissue paper is improved.
Further, when opening the carton, it is necessary to consider the material of the carton in order to prevent the band-shaped cutout portion 13 from breaking or causing a cut in the periphery of the opening. The carton in the present invention is preferably manufactured from cardboard made from wood pulp, waste paper, or the like. In this case, the tear strength specified in JISP8116-2000 is in the range of 2500 to 2900 mN in the vertical direction and 3000 to 3400 mN in the horizontal direction. Preferably, there is. If the tear strength is too low, it is easy to break, and if the tear strength is more than necessary, it is difficult to form an opening, which is not preferable. In a conventional carton containing sanitary paper, thick paper having a tear strength specified in JISP8116-2000 of about 2300 mN in the vertical direction and about 2800 mN in the horizontal direction is used. It can be said that it is preferable to use a cardboard with increased strength.

  In addition, it was confirmed that the filmless carton of the present invention is superior to other conventionally proposed filmless cartons in the following points, and that the same effect as the conventional carton with film can be obtained. That is, the filmless carton of the present invention has the first flap and the second flap at the outlet, and the opening is large, so that the portion of the carton where the tissue touches is small, and since the opening has a smooth shape, the flap can be used. When opening and taking out a set of tissues one by one, (1) the sound of taking out the tissue is almost as low as a conventional carton with film. (2) There is little paper dust when taking out the tissue.

In general, cartons containing sanitary paper such as tissue paper are stacked in a pack of a plurality (usually 5 units as one unit), and the periphery thereof is wrapped in a film and sold in the market. It is convenient for the user to incorporate a carton stand member into the packaging pack. The stand member may be manufactured separately from the carton using cardboard, or may be manufactured from the lower plate of one of the five cartons, for example. Of course, the stand member may be obtained from two or more cartons, and the carton provided with such a stand member is packaged together with a carton having a structure of an outlet or a structure having an outlet on both upper and lower surfaces. It is not limited to what you do. Further, an adhesive, a magnet, or the like may be provided on the back surface of the stand member or the like, and the stand member may be mounted on a refrigerator, a kitchen cabinet, a table wagon, an office desk, or a dashboard of an automobile. FIG. 12 is a developed view showing an example of a case where the stand member is integrated into the lower plate 2 of the carton of the present invention. FIG. 13 is an explanatory diagram of a method of assembling the stand member S cut from the lower plate 2 of FIG.

Inner flaps 25 provided on both sides are insertion grooves into which insertion flaps formed at the bases of the inner flaps are inserted. FIG. 14 is an explanatory diagram in which the carton C of the present invention is held vertically by the assembly type stand member S.
When such a stand member is used, there is no problem in the place where the carton is placed, and when taking out the tissue paper, particularly in the case of the upper and lower both-side taking-out structure, the effect is great, and the operability of taking out the tissue paper is improved.
