Description

The present invention mainly relates to a carton storing sanitary paper such as tissue paper. More specifically, a paper take-out opening (opening) for taking out sanitary paper is provided on at least one of the upper and lower surfaces of the paper box, and a window pasting film for covering the take-out opening is not required on the inner surface of the box. The present invention relates to a structure of a so-called film-less tissue carton outlet.
In particular, the present invention takes into account the operability and safety during use, and the shape of the cut-out part forming the outlet is easy to handle with a hand and has a gentle impression, and is stacked and stored inside the box. Make it easy to take out the first sheet of paper from the outlet, and when the second and subsequent sheets are pulled out of the outlet, they can be taken out in a straight line in the vertical direction or crossed in the diagonal direction. In this case, the present invention relates to a structure of an outlet that can be easily taken out.
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 storing tissue paper widely used in homes and offices has a structure in which an outlet for taking out tissue paper is provided on one surface of a substantially rectangular parallelepiped storage box (usually the upper surface of the box). The user cuts off the cut piece along a substantially elliptic perforated cut line provided on one surface of the box (usually the upper surface of the box), and opens the outlet (opening) to be elongated. A film such as a polyethylene film covering the outlet is usually attached to the inner surface of the outlet, and a linear slit is provided at the center of the film (see, for example, Patent Document 1).
In such a carton, the tissue paper as the contents is pulled out through the slit of the film. The tissue paper inside the carton is usually folded and stored alternately as a set of two sheets so that each set can be continuously removed from the box, and when one set of tissue paper is pulled out from the slit, 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 film adhered to the inner surface of the box protects the contents against external dust and foreign matters, and when taking out the tissue paper, so-called pop-up tissue paper is caused by friction between the slits of the film. It prevents falling into the box and holds the tissue paper in place.

On the other hand, a so-called “film-less tissue carton” having a structure in which the film is not attached to the inner surface of the outlet has been already proposed for the purpose of omitting the material cost of the plastic film such as polyethylene and the process of attaching the film to the box. . That is, a tissue paper packaging box is known in which a film is not attached to the outlet of the tissue paper box and the outlet can be opened in a double-spread shape (see, for example, Patent Document 2, Patent Document 3, and Patent Document 4). .).
Also, in the “film-less tissue carton” similar to the previous example, the tissue paper being taken out is opened by opening the both ends in the longitudinal direction of the outlet, which is elongated in the longitudinal direction of the box and having a substantially diamond shape, into a specific angular shape. A tissue paper carton is known that can be held at both ends of the take-out port so as not to drop into the box (see, for example, Patent Document 5).
Furthermore, a carton is also known in which the shape of the take-out port is not limited to a rhombus, and slits are formed at both end edges of the take-out port to sandwich tissue paper (see, for example, Patent Document 6).

In recent years, with regard to the disposal of waste, which is one of the environmental problems, the “Container Recycling Law” has been established in 1997, which clarifies consumer's separate discharge, municipal collection, and business owner's recycling responsibilities, especially for container and packaging waste. Since then, the movement toward the construction of a recycling-oriented economic society is accelerating. In such a movement, when discarding used cartons of tissue paper such as tissue paper and kitchen paper, the plastic film stuck to the outlet must be peeled off from the carton body, separated and discarded, There is a new problem that it takes time and effort. Therefore, the “film-less tissue carton” saves the trouble of separating the carton into paper and plastic when it is collected and recycled as waste paper, and can be used for recycling by simply crushing it as it is. It attracts attention and its demand is increasing.
For this reason, the present applicant has also proposed a “film-less tissue carton” (for example, see Non-Patent Document 1).
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 Oji Paper's public relations magazine “Miki no Hibiki”, Oji Paper Public Relations Office, published on June 20, 2003, summer issue, pages 25-26

  However, in the above-mentioned “film-less tissue carton”, in the case of the above-mentioned Patent Documents 2 to 6, when the shape of both ends of the outlet is linear or the shape of the flap end is square, The problem is that tissue paper can easily get caught at the corners of the outlet when taking it out, it can be torn when it is pulled upward, and tissue paper can not be taken out smoothly in a pop-up manner. There is. In addition, there was a problem that the sound generated when the tissue paper was rubbed with the box during extraction was unexpectedly loud.

  The paper strength of tissue paper is a problem with the paper strength in the direction of pulling out the tissue paper held in the storage box, but paper strength is also related to other quality requirements of tissue paper and it is easy to change is not. In addition, the larger the size of the tissue paper outlet, the harder it is torn, but if it is too large, it becomes difficult to hold the popped up tissue paper at a predetermined position of the outlet, and it becomes easy to fall into the box.

  On the other hand, in the carton shown in Patent Document 5, the opening angle at both ends in the longitudinal direction of the substantially diamond-shaped outlet is set from 60 degrees to 170 degrees. If the opening angle is less than 60 degrees, the tissue is used. When the paper is taken out, it is caught at the corners and becomes torn or difficult to take out. On the other hand, when it exceeds 170 degrees, the gripping function is lowered and the tissue paper tends to fall into the box.

  Further, in the case of the carton of Patent Document 6, since the entrance of the slit is narrow, it cannot be said that the tissue paper is easy to be taken out, and the shape of the slit portion is not a smooth shape, so that the tissue paper is caught on the corner portion. .

  As an attempt to improve the above-described problem, the present applicant discloses “filmless box” according to Non-Patent Document 1. This “filmless box” has a structure in which a paper take-out opening formed by a zipper-type cut-out portion and a pair of flaps for holding paper on both front and rear sides of the take-out opening are provided. This “film-less box” is formed by arc-shaped curves at the left and right ends of the cut-out part that forms the outlet, so that when the tissue paper in the box is pulled out, the corner of the cut-out part etc. This prevents the tissue paper from being caught and torn, and allows the tissue paper to be removed smoothly and continuously in a pop-up manner without dropping the tissue paper into the box during use. However, since the shape of the cut-out portion forming the paper outlet is a thin band, it is difficult to pick up when opening the zipper and it is difficult to open the zipper. Also, when opening, there is a risk that the hand will be rubbed and damaged by a narrow cutout. In addition, since there is no room at the take-out port, it is difficult to take out the first sheet of paper that is stacked and stored inside the box from the exit, and it is also used when the second and subsequent sheets are taken out from the take-out port. When a person's dominant hand is pulled out or the paper is pulled in an oblique direction, there are disadvantages such as damage to the flap portion or paper catching on the flap.

  Accordingly, the filmless tissue carton of the present invention provides a sanitary paper carton that solves the above-described problems and is easy to open and easy to take out the first and second and subsequent tissue papers after opening. In addition to solving the problem of being caught by a corner and tearing, tissue paper can be taken out smoothly and continuously in a pop-up manner without the tissue paper falling into the box during use. Furthermore, the present invention provides a film-less tissue carton that eliminates the need to separate paper and plastic when discarded after use.

In order to solve the above problems, the first aspect of the present invention is that a cut line is formed along the shape of the outlet in order to form an outlet for the paper stored in the box on at least one of the upper and lower sides of the box. And in a carton with sanitary paper in which a film covering the outlet is not arranged inside the surface having the outlet,
The cut-out part forming the take-out port consists of a band-like cut-out part at the middle part and end cut-out parts at both ends in the longitudinal direction,
In the band-shaped cutout portion of the intermediate portion is formed in a shape that the central portion is constricted, both end portions are formed in a shape that is wider than the central portion,
In the end cutout portion at both ends in the longitudinal direction, it is formed wider than the band cutout portion while being formed integrally with the band cutout portion,
In addition, on both sides of the cutout portion forming the takeout opening, a first hinge portion formed by a curved broken line that bulges outward along the longitudinal direction of the box is formed, and the cutline And a pair of horizontally long first flap portions surrounded by a curved broken line constituting the first hinge portion, and further along the short side direction of the box outside the both longitudinal ends of the cutout portion. Forming a second hinge part constituted by a polygonal line, a tongue-shaped second flap part in contact with the end cutout part is formed;
It is a carton with sanitary paper, characterized by

  A second aspect of the present invention is the sanitary paper-filled carton according to the first aspect of the present invention, wherein the band-shaped cutout portion has a shape narrower toward the center.

  According to a third aspect of the present invention, there is provided the sanitary paper-containing carton according to the first or second aspect, wherein the cut line for forming the strip-shaped cut portion comprises two or two sets of cut lines. .

  According to a fourth aspect of the present invention, an end cut line constituting the outer edge of the end cut portion is formed as a smooth cut line having a wavy shape, and the end cut portion is formed by the wavy cut line. Is a sanitary paper-filled carton according to any one of the first to third inventions, characterized in that a double-hill shaped knob is formed.

  A fifth aspect of the present invention is the sanitary paper-containing carton according to any one of the first to fourth aspects, wherein the strip-shaped cut-out portion and the end cut-out portion are separated by a broken line.

  The sixth of the present invention is configured such that the strip-shaped cut portion and the end cut portions located at both ends thereof can be separated by a cut line, and so as to bite into both longitudinal ends of the strip-shaped cut portion, The sanitary paper-filled carton according to any one of the first to fourth inventions, wherein the fingertip pressing portions connected to the end cutout portions are formed so as to face each other.

  According to a seventh aspect of the present invention, a cut line that divides the band-shaped cut portion and the end cut portions located at both ends thereof is connected to a substantially fan-shaped arc-shaped cut line and bases at both ends of the arc-shaped cut line. The sanitary paper-filled carton according to the sixth aspect of the present invention, wherein the carton is formed by a straight cut line.

  According to an eighth aspect of the present invention, a holding portion for sandwiching sanitary paper is formed between the substantially sector-shaped arc-shaped cut line and the first flap portion after the end cut portion is cut. A sanitary paper-filled carton according to the seventh aspect of the invention.

  According to a ninth aspect of the present invention, the curved fold lines provided on both sides of the pair of first flap portions are formed by shallow embossed stripes whose end fold lines are thicker than the central fold line. A sanitary paper-filled carton according to any one of the first to eighth inventions.

  The carton containing sanitary paper such as tissue paper and kitchen paper of the present invention divides the cut-out part forming the paper outlet into an intermediate part and both longitudinal end parts, and in the intermediate part, the central part is It is formed in a constricted shape, and both end portions are formed in a shape wider than the central portion, and both end portions in the longitudinal direction are formed so as to be wider than the intermediate portion while being formed integrally with the intermediate portion. Thus, by finishing the shape of the cut-out part forming the paper outlet into a substantially bow-tie shape, the appearance of the opening becomes a graceful and soft impression, and the appearance is excellent. In addition, by widening both longitudinal ends of the cutout portion that forms the outlet, both ends can be easily picked and opened when the outlet is opened. In addition, after opening the first sheet of sanitary paper, the finger can be easily inserted into the wide outlet end, and the first sheet can be securely picked up. There is no risk of scratching your hands. Furthermore, since the outlet is formed symmetrically on the left and right and front and back, it can be used in various ways such as flat or standing, and it is easy to use for anyone regardless of the user's dominant hand. Has been made.

Further, even if no film is disposed at the outlet, the intermediate portion of the outlet is constricted, and the paper is taken out while being sandwiched between the pair of first flap portions which are horizontally long and project from both sides toward the intermediate portion of the outlet. Therefore, the paper in the middle of taking out does not fall into the box, and the taking out is easy. Further, since the paper is easily taken out one by one or one set by the sandwiching action of the pair of first flap portions, it is possible to prevent the paper from being overlapped and taken out more than necessary.
In addition, since both end portions in the longitudinal direction of the take-out port are formed as smooth cut lines having a wave shape, the tissue paper is not caught and broken by the both end portions of the take-out port when taking out the tissue paper or the like. In particular, in the case of tissue paper in a box, the folding direction of the tissue paper is alternately changed because the folding is called an interfolder, and the direction in which the tissue paper is taken out changes alternately. As a result, the tissue paper is smoothly moved in the take-out direction, which is excellent in preventing paper tearing and catching. In addition, the friction between the box and the tissue paper is reduced at the time of taking out the tissue paper by such an action, and the sound of taking out the tissue paper is hardly generated and can be taken out gently.
Further, by narrowing the width of the central opening at the take-out port, the structure is such that dust and foreign matter do not easily enter when the paper is not taken out.

Further, according to the present invention, when the carton is opened, the opening area of the cutout portion forming the tissue paper outlet is made large or small, as shown in FIG. 13 or FIG. Can be adjusted.
Furthermore, since it is not necessary to dispose a film inside the outlet, it is not necessary to separate the paper carton from the film at the time of disposal, and the product is environmentally friendly. Further, by eliminating the film, not only the material cost can be saved, but the manufacturing process can be shortened, and energy saving and resource saving can be achieved.

Next, the present invention will be described in more detail based on embodiments of the present invention.
The present invention is a substantially rectangular parallelepiped carton for storing sanitary paper such as tissue paper and kitchen paper, and has a paper outlet on at least the upper surface. In this invention, sanitary paper stored in a carton is tissue paper (also called facial paper, decorative paper, etc.), dust paper, paper towel (kitchen towel, kitchen sheet, paper used mainly in kitchens called cooking sheets) Disposable paper such as toilet paper (excluding rolls), Watting (paper cotton), etc. (refer to Paper Pulp Technology Handbook 5th edition, page 459, issued on 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. In general, the term “tissue paper” is often used to refer to general disposable paper such as facial paper, toilet paper, etc., but in a narrow sense, it usually has a dry crepe and is mainly used for facial wipes. This is used only for tissue paper, and the latter is used in this specification. 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 a so-called film-less tissue carton outlet that is not provided.

The present invention has an outlet having a shape similar to a “bow tie” constricted in the center and spread toward the longitudinal ends of the box on at least one upper and lower surfaces of the box. A sanitary paper-filled carton without a film on the inside, and a cut line 11 extending in the longitudinal direction of the box for forming a cut-out part for an outlet, and end parts continuous to both ends of the cut line 11 A score line 12 is provided. A substantially bow-tie-shaped cutout (opening cutout) 13 is formed by being surrounded by both the cut lines 11 and 12 forming the takeout opening, and extends outside the cutout 13 in the longitudinal direction of the box. A first hinge part formed by a curved broken line 16 bulging toward the outside of the box is formed. Thus, a pair of horizontally long first flap portions 17 surrounded by the cut line 11 and the curved broken line 16 constituting the hinge portion are formed.
Further, a tongue-like second hinge portion formed by a curved broken line 18 bulging outward along the short direction of the box is formed outside both longitudinal ends of the cutout portion, Second flap portions 19 and 19 surrounded by the end cut line 12 and the curved broken line 18 are formed. The polygonal line 16 outside the cut line and the polygonal line 18 outside the end cut line can also be formed by normal ruled lines.
Further, a broken line 15 is provided in the vicinity of both ends of the opening cut-out portion 13 to divide the cut-out portion 13 into a central band-like cut-out portion 24 and end cut-out portions 14 at both ends, and the end cut-out portion 14 is cut off. The band-shaped cutout portion 24 and the end cutout portion (pickup portion) 14 are configured to be cut out integrally from the top surface of the box. At the time of opening, the end knob 14 used as the knob of the opening cutout 13 is formed in a wide and double hill shape so that it can be easily picked up.

  The cut line 11 extending in the central longitudinal direction of the box may be formed by a straight cut (slit) or may be a perforated cut having a partial connection, and is referred to as a “zipper” in the packaging industry. The breaking line for opening in which the cut is bent into a bowl shape (see page 281 of the well-known and commonly used techniques in the packaging industry, issued by the Japan Patent Office on December 20, 1978), or a double line perforation.

  The cut line 11 may be parallel or curved at a predetermined interval in the width direction of the cut portion for forming the take-out port. For example, as shown in FIG. 1, it can be formed by a cut line that is bent so that the central portion is constricted and gradually increases from the central portion toward both ends.

  On the other hand, the end cut line 12 is constituted by a wave-like curve, and is formed by a continuous smooth wave-like curve, for example, as shown in FIG. This cut line may be a perforated cut line or a zipper, but in order to make the cut surface smooth, it should be a continuous cut or a discontinuous cut having a connecting part (connecting part) shorter than the cut dimension. Is preferred.

  When taking out the sanitary paper stored in the carton from the outlet 10, press one of the second flaps 19 formed at the end of the outlet with your finger, push it into the box, Break the connected corrugated pinnacle-shaped knob 14, insert a finger through the open portion, pick up the pinnacle-shaped knob 14, The cut portion 13 formed integrally with the knob is cut from the top surface of the box and opened. After opening, insert a finger from the wide end of the outlet, pinch the uppermost first sanitary paper and pull it upward. The pair of first flap parts 17 are pulled out while being inclined obliquely upward along the curved fold line 16 swelled outside the box in accordance with the force when pulling out the sanitary paper. It is. Then, when the next sanitary paper is pulled out, the first flap portion 17 rising from the opened portion and the tongue-shaped second flap portion 19 protruding from both ends of the take-out port elastically sandwich the sanitary paper. Also works to hold in. Further, when the sanitary paper is taken out, the second flap portion 19 also functions as a guide piece that smoothly guides the sanitary paper withdrawing direction alternately.

As described above, the broken line 18 constituting the hinges of the pair of second flap portions 19 has a curved shape, preferably an arc shape, which bulges toward the long side of the upper surface of the carton (outside the box). When the flap is opened obliquely upward, a force that tends to close (a force to return to the state before bending) acts on the flap. For this reason, the sanitary paper being taken out is elastically sandwiched between the pair of second flap portions 19 and a force is held to hold the sanitary paper in a predetermined position in the opening, and the sanitary paper is pressed upward from the opening. The sanitary paper can be prevented from falling into the carton even if the sanitary paper is reduced. When the sanitary paper is not taken out, the second flap portion acts as a lid to return to the state before the folding, and functions to prevent the entry of external dust and foreign matter.
In this way, the closing force acts on the flap, and the operation and effect of holding the sanitary paper and playing the role of the lid are the same for the first flap portion.

  As described above, the sanitary papers stacked in the box are alternately folded one by one, so that the pulling directions are alternately switched when being pulled out. Therefore, the 2nd flap part 19 with the semicircle-shaped outer edge comprised by the smooth waveform curve is formed in the both ends of an extraction port. The second flap portion 19 protruding in a semicircular shape has an action of distributing the sanitary paper drawer direction alternately, and is taken out by the outlet end portion including the second flap portion and the first flap edge. It functions as a pinching part that holds the sanitary paper inside.

  If the interval between the cut lines constituting the opening cut-out portion 13 is too narrow, it will be difficult to cut out the cut-out portion for opening, and if it is too wide, dust and foreign matter will easily enter the carton. Therefore, the interval is 5 to 15 mm at the narrowest portion of the central portion of the cutout portion 13 and the interval is about 20 to 50 mm at the widest portion at both ends of the cutout portion 13. It is preferable to form a width of about two.

  In addition, the longitudinal dimension of the first flap portion 17 is about 65 to 100% when expressed as a ratio to the dimension of the sanitary paper stored in the carton long side direction (size of sanitary paper). Preferably, 75 to 95% is more preferable. If this ratio is small, the sanitary paper is torn and difficult to take out, and if this ratio is too large, the sanitary paper that should come out of the outlet 10 and be held easily falls into the box. For the same reason, the dimension in the longitudinal direction of the cutout portion 13 for opening (minimum dimension at the center) is 50 to 95% when expressed as a ratio to the dimension in the carton long side direction of the sanitary paper stored. It is preferable that it is about 65 to 85%.

The carton of the present invention has the outlet 10 on at least the upper surface, but a pair of bottom raising members may be formed on the lower surface facing the upper surface. By providing the bottom raising member on the lower surface in this way, when the remaining sanitary paper is reduced, it is bent approximately 90 degrees inside the carton, and the sanitary paper inside is pushed up to the upper surface side, thereby the last one of the sanitary paper. It is possible to pop up stably up to a sheet, and it becomes easy to take out sanitary paper.
In addition, when a carton having the take-out port of the present invention on the upper surface is used with the side facing down and vertically, when the bottom raising member is folded inside the carton, the bundle of sanitary paper in the box is weighted. Therefore, it is possible to prevent the sanitary paper from being taken out and to be used particularly in a narrow place.

  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 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 box structure is conventional (tissue paper). Carton).

  FIG. 1 is a development view showing an example of a carton according to the present invention in which a curved tissue paper outlet is provided on the upper surface of a box. FIG. 2 is a perspective view showing an example of a usage state when the tissue paper is taken out from the outlet on the upper surface of the carton in FIG. FIG. 3 is a cross-sectional view showing an example of a usage state in which the bottom raising member provided on the lower surface of the carton is bent inward.

  As shown in FIG. 1, the carton of the present invention is formed by punching cardboard into a required unfolded shape to form a carton blank having a broken line or a cut line, and this blank is assembled and used in a rectangular parallelepiped shape via the broken line. This carton is provided with a tissue paper outlet on the top of the box, so that it can be easily removed when the tissue paper in the box is low on the bottom surface, and to prevent the tissue paper from dropping. This is an example in which a push-up piece is provided. In FIG. 1, reference numerals 1 and 2 denote a rectangular upper surface plate and lower surface plate, both of which are formed symmetrically. Reference numerals 3 and 4 denote a pair of rectangular side plates, and reference numeral 5 denotes a glue piece connected to one side edge of the bottom plate. The top plate 1 and the bottom plate 2 are formed wider than the side plates 3 and 4. The tissue paper outlet 10 is formed on the top plate. Reference numerals 6 and 7 denote end plates 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 plates 3 and 4. The end face plates 6 and 7 are folded over the inner flaps 8 and 9 to seal the both end faces of the cylindrical box body when the carton is manufactured. The dimensions of the end face plates 6 and 7 are formed such that when the both end faces of the cylindrical main body are sealed at the time of box making, the end portions of the end face plates are overlapped and fixed together.

Next, the structure of the tissue paper outlet will be described with reference to an embodiment. The tissue paper outlet 10 shown in FIG. 1 is elongated in the longitudinal direction at the center of the top plate 1. That is, the take-out port 10 has two perforated opening cut lines 11 and 11 at predetermined intervals in the longitudinal direction of the box at the center of the upper surface plate, and both ends of the cut lines 11 and 11. Are surrounded by wavy end cut lines 12, 12 connecting the two.
And, in the opening cutout portion 13 that forms the outlet 10, a band-shaped cutout portion 24 is formed surrounded by the cut lines 11 and 11, and a knob-part folding line 15 is provided at both ends of the band-like cutout portion 24, A double-knob-shaped knob portion (edge cutting portion) 14 surrounded by the end cutting line 12 and the knob line 15 is formed. The strip-shaped cutout portion 24 and the double-hill shaped knob portion 14 are integrally formed to constitute the cutout portion 13 for opening, and are separated from the top plate 1 to open the outlet 10.

  The cut line 11 in FIG. 1 is an example of a curved cut line curved inward. Therefore, the width of the band-shaped cutout 24 is narrow at the center and gradually increases toward both ends. Furthermore, the double-hill shaped knob 14 connected to the strip-shaped cutout 24 is wide enough to be picked up with a finger when opened and is easy to pick up. Moreover, the wave-shaped edge part cut line 12 is comprised by the discontinuous cut line which has a connection part (connection part).

On both sides of the opening cut-out portion 13, hinge portions are formed which are formed by curved broken lines 16 extending in the longitudinal direction of the box and slightly bulging toward the outside of the box.
A horizontally long first flap portion 17 surrounded by the opening edge of the outlet 10 opened by the cut line 11 and the end cut line 12 and the curved bent line 16 is opposed to the outlet 10. A pair is formed on the long side so as to protrude to the center.

  In addition, a curved fold line 18 bulging outward is disposed outside the wavy end cut line 12, and a tongue-like shape surrounded by the end cut line 12 and the fold line 18. A second flap portion 19 is formed.

  As shown in FIG. 2, the opening cut-out portion 13 formed by the cut line 11 and the end cut line 12 has a narrow shape toward the center, and the entire cut line has a continuous smooth curved shape. The sanitary paper such as tissue paper taken out from the carton can be sandwiched between the corrugated curved part at both ends of the take-out port 10 and the curved part at the edge of the first flap part 17, and the paper inside the carton can be taken out smoothly. Falling can be prevented. In particular, when the paper is folded and stored alternately like tissue paper, the take-out direction of the tissue paper to be taken out changes alternately at the time of take-out (see FIG. 3). As described above, the outlet end is formed with a continuous smooth wave shape, so that the tissue paper can move smoothly between the sandwiched portions, and the paper can be torn or caught. It is excellent in prevention.

  Further, if the end of the curved bent line 16 constituting the hinge portion breaks, when the tissue paper is pulled out, there is a problem that it is caught and cannot be pulled out smoothly or the tissue paper is torn. In order to avoid breakage at the end of the curved bent line 16 serving as the hinge portion, a small substantially arc-shaped cut line 20 curved toward the long side of the box is formed at the end of the curved bent line 16. The small substantially arc shape may have a radius of curvature of several millimeters, for example, and may be a curve close to an arc instead of an arc. Further, it may be punched into a circle, an ellipse or the like.

  In the case of the carton shown in FIG. 1, the bottom plate 2 is provided with a bottom-up member cut line 21, a folding line 22 serving as a hinge portion is provided, and a pair of bottom-up members 23 surrounded by the cutting line 21 and the folding line 22, 23 is formed.

  Incidentally, in the case of the carton shown in FIG. 1, the dimension in the longitudinal direction is, for example, 242 mm, the dimension in the lateral direction is 116 mm, and the height is 50 mm. Moreover, the dimension of the longitudinal direction of the outlet 10 is formed in 180 mm. Further, the interval between the two perforation cut lines 11 and 11 constituting the opening cutout portion 13 of the outlet 10 is 9 mm at the narrowest portion in the center. It is preferable that the end of the take-out port 10 has a size that allows the tissue paper to be easily taken out by inserting a finger. If the radius of curvature when the curved broken line 16 constituting the hinge portion of the outlet is an arc is too small, the closing force becomes too large, and conversely if too large, the closing force becomes too small. Moreover, this hinge part may be not a circular arc but a curve close to a circular arc, as long as an appropriate closing force can be obtained.

In the carton of the present invention, as shown in FIGS. 2 and 3, when the outlet is opened to take out the tissue paper P stored in the box, either the left or right second flap portion 19 is folded on the broken line 18. Pushing down further, putting a finger under the end cut line 12 to pick up the Futari-shaped knob 15, cut out a series of opening cuts 13 together with the Futari-shaped knob 15 and open it. When the uppermost tissue paper is picked from the wide end of the open outlet 10 and pulled upward, the pair of first flap portions 17 and 17 are obliquely upward along the curved broken line 16 bulging outward. It can be bent and tilts elastically.
Further, the subsequent tissue paper is drawn out from the opened portion, and the open end portion including the opposite sides of the pair of first flap portions 17, the edge of the first flap portion 17, and the second flap portion 19. It is sandwiched and held elastically. In addition, the tissue paper drawn out to the take-out port 10 is slanted so as to obliquely cross the take-out port 10 such as both edges of the opposed first flap portions 17 and 17 and the lower right and upper left of the take-out end portion. It can also be pulled out to be held at the opposite ends.

  In addition, the pair of first flap portions 17 and 17 tend to close when they are opened obliquely upward by forming a bent line 16 serving as a hinge into an arc shape that bulges outward on the long side of the upper surface of the carton. Force to return to the previous state) works. For this reason, the tissue paper being taken out is elastically sandwiched between the pair of first flap portion 17 and second flap portion 19 to hold the tissue paper in a predetermined position, and the tissue paper content is reduced. Also prevents the tissue paper from falling into the carton. When the tissue paper is not taken out, the flap part acts as a cover of the carton to return to the state before the folding, thereby preventing the entry of external dust and foreign matters.

  When the remaining amount of tissue paper in the box decreases, as shown in FIG. 3, the pair of bottom raising members 23 provided on the lower surface plate 2 can be folded and used inside the box. That is, the cut line 21 of the lower surface plate 2 is broken, and the bottom raising member 23 is bent approximately 90 degrees inside the carton with the broken line 22 as a hinge portion, and the bottom raising members 23 and 23 are sequentially bent. The folded tissue raising members 23 and 23 push up the internal tissue paper to the upper surface side. As a result, it is possible to stably pop up from the outlet 10 on the upper surface to the last piece of tissue paper.

  FIG. 4 shows an example different from FIG. 1 of the cut line 11 provided at the outlet 10 of the present invention. FIG. 4 shows an example in which two sets of cut lines each having a perforated cut line formed of double lines are provided. FIG. 4 is an example in which a double line (double perforation line) composed of two parallel perforations having substantially the same dimensions is configured as a set of cut lines, and the double line ( It is a top view of the upper surface board which shows the example by which 1 set of cut lines comprised as a double perforation line are each arrange | positioned at the both sides of the cut part 13 for opening. 2 shows an example in which two perforations having incisions with different dimensions are arranged in parallel, and the incisions of each perforation are arranged in a staggered manner, and the perforations having long incisions are A perforation having a short cut portion located inside the carton is arranged so as to be located outside the carton. If two types of perforations with different cutout dimensions are arranged on both sides of the opening cutout 13 in a zigzag pattern, when the cutout for opening is picked up with a finger and cut off, it is uneven along the perforation. Since the cut surface is formed, it looks good, the edge of the opening cut portion does not fluff or flutter, and the uneven cut surface does not become uneven. In addition, when the cutout portion for opening is cut off, it can be easily opened with a small force, so that it is easy to open and the sound at the time of cutting can be reduced.

Furthermore, even when the carton of the present invention is manufactured with multi-layered white paperboard mainly composed of waste paper, the edge of the opening cutout can be cut out relatively smoothly and smoothly as described above. The upper layer of the surrounding paper can be cut off without being peeled off (paper layer peeling can be prevented). Furthermore, the cut line composed of two parallel perforations having cut portions of different lengths so as to be arranged in a staggered manner on both sides of the opening cut-out portion 13 is formed by connecting the cut portion of the inner perforation. When the outer perforation cut portion is formed to be long, when the opening cut portion is cut, the edge of the opening cut portion is torn cleanly in an uneven shape, so that the appearance of the cut is improved.
Although not shown in the figure, the cut line does not have to be linear, and may be provided in the waveform by a wave blade. Further, the cut line may be finer than a normal perforation called a micro blade, and these can all be used as the cut line of the present invention.

  FIG. 5 shows an example different from FIGS. 1 and 4, and both ends of the curved broken line 16 outside the first flap portion 17 forming the outlet 10 provided in the upper surface plate 1 are thick and shallow embossed lines. And is a plan view showing an example in which a bottom raising member that can be pushed up by one push is provided on the bottom plate. FIG. 6 is an enlarged plan view of the outlet end portion of FIG.

  In the outlet 10 opened by the cut line 11, the end of the curved broken line 16 constituting the hinge portion of the first flap portion 17 is a portion that is likely to break while repeatedly performing the operation of taking out the sanitary paper from the box. . Instead of providing a substantially arc-shaped cut line 20 as shown in the embodiment of FIG. 1 in order to avoid breakage of this portion, as shown in the enlarged view of FIG. 6, the end of the curved broken line 16 is thickened. ing. A normal polygonal line constituting the central part of the curved polygonal line 16 has engraved creases in the entire paper thickness of the carton blank. The folding lines applied to the ends of the curved broken line 16 shown in FIG. 6 are shallow folding lines in which a folding line having a depth of about half the paper thickness of the blank is engraved. The width of the fold line is engraved. By forming a folding line with a width corresponding to three normal folding lines, it is formed to be three times as thick. In this way, the sanitary paper is repeatedly taken out, and the end of the curved bent line 16 that is easily broken by bending the first flap portion 17 is formed into a shallow and thick broken line, thereby strengthening and avoiding breakage. It is made to be able to.

  Further, the bottom raising member provided on the bottom plate shown in FIG. 5 is formed so that the bottom raising member 23 formed by the semicircular cut line 21 is separated into right and left, and can be bent with the folding line 22 as a hinge part. Yes. The bottom raising member 23 formed symmetrically can be bent to the inside of the box at the same time with one push.

  7 and 8 show modifications of the bottom raising member of the carton according to the present invention. These are different in shape from the bottom raising member in FIG. 5, are surrounded by the cut line 21, and are formed to be bendable to the lower surface plate 2 with the fold line 22 as a hinge portion. The bottom raising member 23 is an example of an elliptical shape having a symmetrical shape in FIG. 7, and FIG. 8 is an example constituted by a curve in which a dent is formed in the center of the tip, and the shape of the bottom raising member is as illustrated here. There is no limitation, and various shapes such as curves and broken lines can be used.

FIG. 9 shows an embodiment different from those shown in FIGS. This embodiment is also a plan view of a top plate provided with a tissue paper outlet having a bow tie-shaped opening cutout 13 formed therein.
Two or two sets of cut lines 11 extending in the central longitudinal direction of the upper surface of the box are parallel to the central portion at a predetermined interval in the width direction of the box, from one end thereof to both ends in the longitudinal direction of the box. It is provided in the shape which spreads diagonally so that a width | variety increases gradually. Parallel cutting lines and diagonally extending cutting lines are configured to be connected in the vicinity of the central portion, and wavy end cutting lines 12 are provided at the ends of the diagonally extending cutting lines. ing.
An opening cut-out portion 13 is formed surrounded by the cut line 11, a broken line 15 is provided in the vicinity of both ends of the opening cut-out portion 13, and a double hill shaped pick-up portion (end end) surrounded by the end cut line 12 is formed. Part cutout part) 14 is formed. That is, the opening cut-out portion 13 is formed by a belt-like cut-out portion 24 at the center portion thereof, and a double hill-shaped knob portion 14 formed integrally at both ends, which is cut out from the top plate 1 and the outlet 10 is opened. . The outlet 10 is formed in a shape similar to a bow tie shape.
Moreover, the 1st hinge part comprised by the curved broken line 16 swelled toward the edge of the long side of the upper surface board 1 is formed in the outer side of the cut lines 11 and 11, and the curved folded line 16 and A pair of substantially trapezoidal horizontally long first flap portions 17 surrounded by the cut line 11 is formed. In addition, a fold line 18 parallel to the short side of the top plate 1 is provided outside the double hill knob 14, and a tongue-shaped second flap portion 19 surrounded by the end cut line 12 and the fold line 18 is provided. Is formed.
The outlet 10 shown in FIG. 9 is the same as that shown in FIG. 1 in the opening procedure and the action of the first flap portion 17 and the second flap portion 19 when taking out the sanitary paper.

  Also in this embodiment, since the tissue paper outlet 10 of the carton is formed in the center of the top plate in a symmetrical shape in the left-right direction, there is no discrimination between the left and right sides of the carton. Therefore, the user can use it without being influenced by the dominant hand. In addition, the carton can be placed either horizontally or vertically for use in a narrow place. Further, even when the remaining tissue paper is reduced, the take-out property of the tissue paper does not deteriorate.

FIG. 10 is a plan view showing another example of the tissue paper take-out part of the present invention, and FIG. 11 is an enlarged view of a main part of the take-out part shown in FIG.
The carton with sanitary paper shown in this embodiment is configured such that the cut-out portion 13 forming the tissue paper outlet 10 is divided into an intermediate band-like cut-out portion 24 and end cut-out portions 14 located at both ends thereof. This is the same as the embodiment described above. The difference is that both the cut-out portions 14 and 24 can be divided and separated by discontinuous cut lines 25 and 26 having a connection (connection portion).

  That is, the carton shown in this example can be cut and removed in accordance with the user's needs for either one or both of the intermediate band-shaped cut portion and the end cut portions located at both ends. The opening area can be adjusted. Specifically, when the user of the carton wants a small outlet when the outlet 10 is to be cut and removed, if the user does not remove the end cut portion 14, dust will enter the box. When the carton user wants a large outlet, if the user removes the end cutout 14, the opening area of the outlet increases, and the tissue paper can be easily taken out. .

  In the carton shown in this example, the fingertip pressing portions 27 and 27 that are necessary when opening the outlet are provided at both ends in the longitudinal direction of the strip-shaped cutout portion 24 located in the middle. It is formed so that it may become a pair. The fingertip pressing portions 27 and 27 are provided such that arc-shaped cutting lines 25 and 25 each having a substantially fan shape in order to form the fingertip hole 28 bite into both longitudinal ends of the strip-shaped cutout portion and face each other. Further, by providing straight cut lines 26 and 26 that are connected to the bases of both ends of the arcuate cut line 25 having a substantially fan shape, the middle band-shaped cut portion 24 and the end cut portions 14 located at both end portions thereof. Are configured to be separable. A holding portion 29 for sandwiching the end portion of the tissue paper is formed between the substantially arc-shaped arc-shaped cutting lines 25 and 25 and the first flap portion 17. Here, the “fan-shaped arc-shaped cut line” is not limited to the 180-degree arc-shaped cut line shown in FIG. It is a concept including an arcuate cut line including an acute angle.

  In the above configuration, when the outlet 10 is cut off and removed, the fingertip is pressed against one of the fingertip pressing portions 27 and 27 surrounded by the substantially arc-shaped cutting lines 25 and 25 to open the cover. After that, the middle strip-shaped cutout 24 is pulled up by sliding the fingertip into the backside while keeping the fingertip hooked in the fingertip hole 28. Further, as shown in FIG. 12, the strip-shaped cutout portion 24 is removed by pulling the strip-shaped cutout portion upward along the cut line 11 from the end. At this time, the strip-shaped cutout portion 24 that is easily torn is torn in the direction of the cut line 11, so that it can be torn with a small force, and when the strip-shaped cutout portion 24 is cut off, the surrounding paper is peeled off and the appearance is removed. There is no loss.

Next, a method for adjusting the opening area of the outlet will be described. FIG. 13 (A) is a diagram showing a situation in which a middle strip-shaped cutout is removed and both end cutouts located at both ends are left in the cutout forming the tissue paper outlet. is there. FIG. 13 (B) is a diagram showing a situation in which one of the middle strip-shaped cut-out portion and the end cut-out portions located at both ends is removed and the other is left in the cut-out portion forming the tissue paper outlet. .
Moreover, FIG. 14 (A) is a figure which shows the condition which opened the cutout part which forms a tissue paper taking-out opening completely. FIG. 14B is a diagram illustrating a state in which the end cutouts located at both ends are removed and the intermediate band cutouts are left in the cutout forming the tissue paper outlet.
In the figure, the hatched area indicates the opening location. Thus, when opening the carton, as shown in FIG. 13 (A-B) or FIG. 14 (A-B), a cutout portion that forms a tissue paper outlet according to the needs of each user. There is an effect that the opening area can be adjusted to be large or small.

In the above configuration, as shown in FIG. 13 (A), when the fingertip pushing portions 27 and 27 are connected to the end cutout portion 14 so as to face the inside thereof, the remaining fingertips Since the shape of the pushing parts 27 and 27 is formed in the substantially fan-shaped arc shape, when pulling out the first tissue paper from the inside of the box upward from the outlet 10, the fingertip pushing part is used when taking out the tissue paper. 27 functions as a guide for tissue paper. That is, the tissue paper is gently squeezed along the arcuate portion of the fingertip pressing portion 27 and is smoothly taken out without being caught.
Further, the end of the next tissue paper drawn out from the carton following the extracted tissue paper is gently squeezed along the arcuate fingertip pushing portion 27 and enters the holding portion 29, where the holding is performed. The portion 29 holds the end of the tissue paper in a standing state. Therefore, the take-out property of tissue paper is further improved.

  The present invention is not limited to the above-described embodiment, and it is needless to say that various modifications can be made without departing from the gist of the present invention. For example, if a lottery or fortune-telling is appropriately printed on the back surface of the strip-shaped cutout portion or the end cutout portion, the enjoyment of cutting the strip-shaped cutout portion or the end cutout portion can be enjoyed. In addition, if you print points and gift vouchers, you can enjoy collecting points and enjoying presents.

Further, the curved bent line 16 constituting the hinge of the first flap portion can be formed by a perforation in addition to a normal folding line according to the degree of required stress. The first flap portion 17 may be easily opened and closed by a means such that the eyes are alternately repeated.
Further, in the example of FIG. 10, both the cutout portions 14 and 24 are configured to be separated by the cut lines 25 and 26, and the fingertip pressing portion 27 is provided so as to be integrated with the end cutout portion 14. However, as shown in FIG. 15 (A) or (B), the linear cut line at the boundary between the strip-shaped cut portion and the end cut portion is replaced with the broken line 15, and an opening is formed by the fingertip pushing portion 27. Therefore, it is possible to cut the entire band-shaped cutout portion 24 and the end cutout portion 14.

  In addition, when opening the carton, it is necessary to consider the material of the carton in order to prevent the opening cutout 13 from breaking or causing a break in the periphery of the opening. The carton in the present invention is preferably produced from cardboard made from wood pulp, waste paper, etc. 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 it is more than necessary, it is difficult to form the opening, which is not preferable. In the conventional carton containing sanitary paper, cardboard 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 cardboard with higher strength.

In addition, the filmless carton of the present invention was superior to other conventionally proposed filmless cartons in the following points, and it was confirmed that the same effect as the conventional carton with a film was obtained. That is, the filmless carton of the present invention can be easily opened without damaging the fingers, and can easily take out the first set of paper stacked and stored inside the box from the outlet. When the paper is also pulled out from the take-out port, it can be taken out in a straight line in the vertical direction or crossed in the diagonal direction, so that the user can use it without being influenced by the dominant hand. Also, there are few parts where tissue touches at the carton outlet, and the opening shape is smooth, so when taking out tissue one by one,
(1) The sound when taking out the tissue is almost as low as a conventional carton with a film. (2) Little paper dust is generated when removing tissue.
