Description

The present invention mainly relates to a carton storing sanitary paper such as tissue paper. More specifically, a so-called film in which an exit (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 covering the exit is not required on the inner surface of the box. It relates to the structure of the outlet of the Resty Carton.
In the present invention, “sanitary paper” refers to tissue paper (what is called facial paper, decorative paper, etc.), dust paper, paper towels (kitchen paper, etc.), toilet paper (excluding rolls), and Watting (paper cotton). ) And other disposable papers.

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 (see Patent Document 1).
A straight slit is provided in the center of the film, and the tissue paper as the contents 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 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 by reducing the opening area of the outlet, and when taking out the tissue paper, This prevents the so-called pop-up tissue paper from falling into the box due to the friction at the top and holds the tissue paper in a predetermined position.

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 used at the outlet of the tissue paper in a box, and the outlet can be opened in a double-sided manner (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 cartons containing tissue paper that can be held at both ends of the take-out port so as not to drop into the box are known (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).

  On the other hand, a tissue paper box is known in which tissue paper outlets are provided on the top surface of a tissue paper carton and the bottom surface opposite to the tissue paper so that the tissue paper can be taken out from both sides of the carton. (For example, see Patent Document 7).

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 this movement, when disposing of used cartons of sanitary paper such as tissue paper and kitchen paper, it is no longer necessary to peel off the plastic film attached to the outlet from the carton body, or the carton is collected and recycled as used paper. The demand for “film-less tissue cartons” is increasing due to advantages such as saving paper and plastic and making it possible to turn it into a recycling process just by crushing it.

  However, in the above-described filmless tissue carton, in the case of the above-mentioned Patent Documents 2 to 6, the tissue paper is externally removed by the shape of both ends of the outlet being linear or the shape of the flap end being angular. When tissue paper is taken out, the tissue paper is likely to get caught at the corner of the outlet, etc., and when it is pulled upward, it can be torn, or the tissue paper can not be taken out smoothly in a pop-up manner. is there.

  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 is likely to enter, and since the shape of the slit portion is not smooth, it can be said that the tissue is easily caught on the corner portion.

In addition, if the outlet is too large, outside dust and other foreign objects can easily enter the box, and when used around the kitchen, mud, dust, or water used in cooking A problem arises in that the oil jumps into the box from the take-out port and easily contaminates or wets the contents that should be kept clean.
By the way, as shown in the said patent documents 1-6, most of tissue paper cartons were provided with the taking-out port for taking out tissue paper in one surface (usually upper surface) of a substantially rectangular parallelepiped storage box. . Since this tissue paper carton has a tissue paper outlet only on the top surface, it can only be used by placing it on a tabletop or floor and taking out the tissue from the top surface outlet. Therefore, if the tissue paper stored in the box is reduced, the lower one becomes difficult to take out. In order to take it out, it was necessary to hold the box with one hand, and in order to lift a small amount of tissue paper, a bottom-up mechanism for raising the bottom had to be placed on the bottom of the box. In use, it has also become a place blockage to take up space on the tabletop or floor.

  As an attempt to improve the above problems, as disclosed in Patent Document 7, tissue paper outlets are provided on the top surface of a tissue paper carton and the bottom surface opposite to the tissue paper, regardless of how it is placed in use. The thing which can take out tissue paper from two upper and lower sides is proposed. However, if there is little remaining tissue paper stored inside the box, there will be a problem that even if a bottom raising mechanism is installed, it will be difficult to hold the tissue paper in place at the outlet and it will easily fall into the box. As a result, the tissue paper may not be smoothly removed from the outlet. In addition, if the tissue paper box is used with its side facing down, the tissue paper bundle inside will be bent by its weight and will slide down downwards, so it will not be possible to stably pop up to the last piece of tissue paper. Has occurred.

The purpose of the present invention is to solve the problem that when taking out the tissue paper to the outside, it will be caught by the corner of the opening, etc. It is to provide a filmless carton that saves time and labor. In addition, another object of the present invention is that tissue paper can be taken out one by one in a pop-up manner smoothly without dropping tissue paper into the box during use, and from the take-out port to the outside. It is to provide a filmless carton having a structure that is difficult for dust and foreign objects to enter.
Still another object of the present invention is to allow the tissue paper to be taken out from both 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. Both standing and vertical (vertical) can be used, it can be used in a narrow place, and the film that makes it easy to take out the tissue paper when the remaining tissue paper is low It is to provide restakun.

In order to solve the above problems, the present invention includes the following means.
The first of the present invention, the upper and lower at least one surface of the box has an elongated outlet in the longitudinal direction of the box, the sanitary paper carton of film on the inner surface with a removal port is not disposed, the The outlet has two or two sets of opening cut lines extending at intervals in the longitudinal direction of the box at the center of the surface having the outlet, and an end cut line connecting the ends. A hinge part constituted by a curved broken line that bulges outward along the longitudinal direction of the box is disposed on both sides of the band-shaped cut part, with the band-shaped cut part surrounded by Two or two sets of opening cut lines and a curved broken line constituting the hinge portion are connected at each end by a curved cut line, and the opening cut line A lead-in line, a curved broken line constituting the hinge portion, and this A pair of first flap portions surrounded by the curved cut line connecting the two are formed, and the pair of first flap portions function as a door after opening the outlet. It is a carton with sanitary paper.

Furthermore, the first invention, the end score line of the strip cutout ends is formed bulging curved towards the inside of the box, the the end of the score line for the opening hinge part The curved cut lines connecting the ends of the curved broken lines constituting the two are formed in a curved shape that swells toward the outside of the box, so that these two cut lines are continuous waves. The take-out end edge portion formed by the wavy cut line and the end edge portion of the first flap portion function as a pinching portion that holds the paper being taken out by frictional force. which is a sanitary paper carton shall be the feature.

A second aspect of the present invention is characterized in that the interval between the two or two sets of cut lines constituting the strip-shaped cut portion is 5 to 20 mm at a narrow interval before opening the outlet. 1 is a carton containing sanitary paper according to the first aspect of the invention.

According to a third aspect of the present invention, a knob folding line is provided in the vicinity of the end of the band-shaped cutout section so as to be substantially orthogonal to the two or two sets of cut lines, and the knob section folding line and the band-shaped cutout section are provided. A sanitary paper-containing carton according to the first or second invention , wherein a knob is formed between the end cut lines.

According to a fourth aspect of the present invention, there is provided a tongue-shaped protrusion that is surrounded by end cut lines at both ends of the strip-shaped cutout section and a cut line at the end of the first flap section, and the root of the protrusion section. a sanitary paper carton as claimed in any one of the first to third aspects of the invention, characterized in that the second flap portions of the pair is formed by arranging a line to the part.

According to a fifth aspect of the present invention, the two sets of opening cut lines are constituted by a double line consisting of two parallel perforations having substantially the same dimensions as one set of cut lines. set of score lines are sanitary paper carton as claimed in any one of the first inventions fourth invention, characterized in that are arranged on both sides of the strip cutout.

According to a sixth aspect of the present invention, the two sets of opening cut lines are a pair of cut lines each consisting of two parallel perforations having different lengths of perforated cut portions. Arranged so that the cuts of the perforations in the double line are arranged in a staggered manner so that the phase cuts are alternately arranged, and the one set of cut lines is the strip cut it is sanitary paper carton as claimed in any one of the fifth invention from a first aspect, characterized in that are arranged on both sides of the section.

According to a seventh aspect of the present invention, the cut line at the end of the first flap portion connected to the curved bent line constituting the hinge portion of the first flap portion is a substantially arc-shaped cut line having a small end portion. Alternatively, the sanitary paper-filled carton according to any one of the first to sixth inventions is characterized in that it has a punched portion and prevents breakage of this portion.

According to an eighth aspect of the present invention, the curved broken line that forms the hinge portion of the first flap portion is a curved shape that swells toward the outside of the box, and when the first flap portion is opened after opening, A sanitary paper-filled carton according to any one of the first to seventh inventions, wherein a force in the closing direction acts on the first flap portion.

According to a ninth aspect of the present invention, the length of the first flap portion in the longitudinal direction is 65 to 100% when expressed as a ratio to the length of the sanitary paper in the carton long side direction. The sanitary paper-filled carton described in any one of the first to eighth inventions.

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

The carton containing sanitary paper such as tissue paper and kitchen paper of the present invention has a pair of first flap portions, particularly the first, that function as a door when taking out the paper, even if a film is not disposed on the surface having the outlet. Since the paper is taken out while being sandwiched between the sandwiching portions formed at both ends of the flap portion, the paper is not dropped during the taking-out, and the take-out is easy. Further, because of the action of the sandwiching portion, the paper is easily taken out one by one or one set, so that it is possible to prevent the paper from being overlapped and taken out more than necessary.
In addition, 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 is caught by the corner of the opening and broken as in the past. There is no. In particular, in the case of tissue paper, since it is folded and stored alternately, the direction in which the tissue paper to be taken out is alternately changed at the time of take-out, so that the pinch portion of the first flap end is also alternately pinched. However, since the curved cut line at the end of the first flap and the end cut line at the end of the cut-off part form a continuous smooth wave shape, the movement between the sandwiched parts is performed smoothly. It is excellent in preventing paper tearing and catching.
Further, when the opening at the take-out port is small and the paper is not taken out, a force acts in the direction of closing the take-out port on the two flaps, so that it is difficult for dust and foreign matter to enter.
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 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 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 the outlet of the 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. The cut line may be a straight cut (slit), or may be a perforated cut having a partial connection, or a cut called a “zipper” in the packaging industry is bent into a bowl shape. A break line for opening is included (see page 281 of the well-known and commonly used techniques in the packaging industry, issued on December 20, 1978), and this is also an example of the cut line of the present invention. In addition, as shown in the below-mentioned Example, this cutting line of the present invention may extend in a straight line substantially in the longitudinal direction of the center of the take-out port. It is constituted by two or two sets of cut lines formed substantially parallel at a predetermined interval. When there are two sets of the cut lines, a plurality of cut lines such as two perforations are arranged as double lines to constitute one set of cut lines.

  One embodiment of the present invention is configured by at least two or two sets of perforated cut lines extending in the longitudinal direction at a substantially central portion in the width direction of the box, located on at least one of the upper and lower surfaces of the box. It has a narrow strip-shaped cutout portion. On both sides of the strip-shaped cut-out portion, hinge portions are formed that are formed by curved broken lines that extend in the longitudinal direction of the box and bulge toward the outside of the box. In addition, a pair of first flap portions of a double door type that can be drawn and are surrounded by the cutout portion and the hinge portion are provided.

  Both ends in the longitudinal direction of the pair of first flap portions are formed in a smooth curved shape bulging outward from the box by a cut line continuous to the pair of hinge portions, preferably in an arc shape. The cut line may be perforated or zippered, but is preferably a continuous cut in order to smooth the cut surface. Further, the sanitary paper being taken out from the inside of the box is pinched by frictional force between the curved opening end portion formed by the cut line and the end portion of the first flap portion, so that the sanitary paper is put into the box inside. Falling can be prevented.

The second embodiment of the present invention is different from the first embodiment in that the number of opening cut lines in the first embodiment is one or one set, and there is no strip-shaped cutout portion. It is almost the same as the form. In addition, one set includes a plurality of cut lines such as two perforations arranged as double lines to form a set of cut lines.
When the sanitary paper stored in the carton is taken out from the outlet according to the present invention, if there is one or one set of opening cut lines (in the case of the second embodiment), the opening cut line is designated. In the case where the belt-like cut-out portion is arranged (in the case of the first embodiment), after cutting out the belt-like cut-out portion, a finger is inserted from the opened portion, and the uppermost sanitary paper When the pin is pinched and pulled upward, the pair of first flap portions are pulled out while rising obliquely upward along a curved broken line bulging outward of the box according to the force. The inclination angle is preferably about 15 to 30 degrees. Furthermore, the next sanitary paper following this is pulled out from the opened portion, and the sanitary paper is also elastically sandwiched and held between the opposing sides of the pair of first flap portions. Of course, it is also possible to open the pair of first flap parts (doors) by bending the first flap part diagonally upward with the finger force, and to form the outlet reliably. In this way, it is preferable to form with “finger power”.

  In addition, as described above, the bent line constituting the hinges of the pair of first flap portions that can be drawn to the left and right is a curved shape that bulges toward the long side of the upper surface of the carton (outside the box), preferably an arc shape. As a result, a force that tends to close when the first flap portion is opened obliquely upward (force to return to the state before bending) is applied. For this reason, a force is exerted to elastically sandwich the sanitary paper being taken out between the pair of first flap portions and hold the sanitary paper in a predetermined position in the opening portion. Can be prevented from falling to. When the sanitary paper is not taken out, the first flap portion acts as a cover of the carton to return to the state before being bent, and functions to prevent intrusion of external dust and foreign matters. The action of holding the sanitary paper is large mainly at both end portions of the first flap part, and this action is small between the opposing sides formed by two or two sets of opening cut lines.

It is preferable that the interval between the two or two sets of cut lines constituting the strip-shaped cut portion is about 5 to 20 mm in a portion having a small interval before opening the outlet. If this interval is too narrow, it is difficult to cut the cut portion, and if it is too wide, dust and foreign matter are liable to enter the carton, which is not preferable.
Further, the length of the first flap portion in the longitudinal direction is approximately 65 to 100% when expressed as a ratio to the length of the sanitary paper stored in the carton long side direction (the length of the sanitary paper). Preferably, it is more preferably 75 to 95%. 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 to be held above the take-out port tends to fall into the box, which is not preferable. For the same reason, the length in the longitudinal direction (minimum dimension of the central portion) of the strip-shaped cut portion is 50 to 95 when expressed as a ratio to the length of the sanitary paper in the carton long side direction. % Is preferable, and 65 to 85% is more preferable.

The carton of the present invention has an outlet on at least the upper surface, but may further have a similar outlet on the lower surface facing the upper surface. When the outlets having the configuration of the present invention are arranged on the two opposing surfaces as described above, when the remaining sanitary paper is reduced, the two holding flap portions at the lower side outlets are approximately 90 degrees inside the carton. By bending and pushing up the internal sanitary paper to the upper surface side, the last one of the sanitary paper can be stably popped up, and the sanitary paper can be easily taken out.
In addition, when a carton having an outlet having the structure of the present invention disposed on two opposing surfaces is used with the side face down and standing vertically, not only the sanitary paper can be taken out from both sides, but also the first inside the carton. When the flap part is folded and used, the bundle of sanitary paper inside can be prevented from curving due to its weight and being displaced downward, so that the sanitary paper can be taken out more easily, especially in narrow spaces such as automobiles. It is convenient to use on the dashboard.

  Further, it is possible to print and use patterns, characters and designs that are visible from the outside when opened on the inner surface of the first flap portion (the inner surface of the box). For example, if a lottery or the like is printed on the surface, the consumer's interest can be enhanced, 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 the figure, the same reference numerals as those in FIG. 1 denote the same parts, and the basic box structure is a conventional one (tissue paper). Carton).
FIG. 1 is a developed view showing an example of a carton of the present invention in which tissue paper outlets are provided on both upper and lower sides of a box. FIG. 2 is a perspective view showing an example of a usage state when taking out the tissue paper from the outlet on the upper surface of the carton in FIG. FIG. 3 is a cross-sectional view thereof. Further, FIG. 4 is an enlarged perspective view showing the tissue paper sandwiched between the flap portions provided at the outlet of the carton of the present invention. FIG. 5 is a plan view in which a zipper-type cut is provided at the tissue paper outlet of the carton of the present invention.

In FIG. 7B, a double line composed of two parallel perforations having different lengths of the perforated cut portion is formed as a set of cut lines, It is an example in which the perforations are arranged in a staggered manner so that the perforations are arranged in a staggered manner, and the incisions having different lengths arranged in a staggered manner are arranged as described above. It is a top view which shows the example by which one set of cut lines which consist of a parallel perforation which has are each arrange | positioned at the both sides of the strip | belt-shaped cutout part 13. FIG.
FIG. 7C is a partially enlarged view of the perforation shown in FIG.

  As shown in FIG. 1, in the carton of the present invention, similarly to the conventional one, a cardboard blank is punched into a required developed shape to form a carton blank with a fold line or a cut line, and this blank is passed through the fold line. Used in a rectangular parallelepiped shape. This carton is usually provided with tissue paper outlets on the upper surface of the box, but FIG. 1 is 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 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 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 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 lengths 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 shown in FIG. 1 is elongated in the longitudinal direction at the center of the upper surface plate 1 and the lower surface plate 2. That is, the outlet has opening cut lines 11a and 11b that extend in the longitudinal direction of the box at the center of each face plate and have two perforations in parallel with a predetermined interval. Yes. Moreover, it has the end part cut lines 12a and 12b which connect the both ends of the said cut lines 11a and 11b, respectively.
The strip-shaped cut portion 13 surrounded by the two perforated cut lines 11 a and 11 b and the end cut lines 12 a and 12 b is formed in the longitudinal direction of the center portion of the upper surface plate 1 and the lower surface plate 2. Are formed respectively.
Further, on both sides of the strip-shaped cutout portion 13, hinge portions are formed which are formed by curved broken lines 14 a and 14 b extending in the longitudinal direction of the box and bulging toward the outside of the box, and the opening cut The lines 11a and 11b are connected to both ends of the curved bent lines 14a and 14b constituting the hinge part by curved cut lines 15a and 15b.

The 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 them. Portions 16 and 16 are formed.
In addition, the tongue-shaped protrusions surrounded by the end cut lines 12a and 12b at both ends of the cutout section 13 and the curved cut lines 15a and 15b are formed at the base portion of the cut portion 13 at the short side of the box. Parallel folding lines 18 are arranged to form the second flap portion 17.
Thus, the curved portions of the second flap portion (curved cut lines 15a and 15b, end cut lines 12a and 12b) and the curved edges of the carton opening (cut lines 15a and 15b) A sanitary paper such as tissue paper taken out from a carton by a continuous smooth wave shape and a curved portion of this wave shape and a curved portion (curved cut lines 15a and 15b) of the first flap end. Can be taken out smoothly and paper can be prevented from falling into the carton. In particular, when tissue paper is folded and stored like tissue paper, the take-out direction of the tissue paper to be taken out changes alternately during take-out (see FIG. 3). Although it is alternately switched (alternately switched to the 15a side and the 15b side), as described above, the tissue between the sandwiched portions is formed by the continuous smooth wave shape formed by the second flap portion or the like. Paper can move smoothly, and it is excellent in preventing tearing and catching of paper.

  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 is It is preferable to form so as to contact via a small substantially arc-shaped cut line 19 that is curved toward the long side. By adopting such a configuration, it is possible to avoid breakage of the ends of the curved bent lines 14a and 14b constituting the hinge portion, and when the tissue paper is pulled out, it can be pulled out smoothly without being caught by the hinge portion. Become. 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. Although the example of the specific shape of this part is shown in FIG. 10, it is not necessarily limited to this. (1) in FIG. 10 shows an example of a partially circular arc having a radius of 1 mm, which is close to an elongated circular shape as a whole. Further, (2) in FIG. 10 shows an arc-shaped example with a radius of 1 mm, and (3) in FIG. 10 shows an arc-shaped example with 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. Moreover, the dimension of the longitudinal direction of the taking-out port 10 is 200 mm, and the dimension of the transversal direction of the carton is formed to 60 mm. In addition, the interval between the two perforation cut lines 11a and 11b constituting the cutout portion 13 of the take-out port is 10 mm in the case of FIG. 1, but the cutout portion can be easily cut out by inserting a finger. It is preferable that the size is as large as possible, and is preferably about 5 to 20 mm. Note that the curvature radius when the curved broken lines 14a and 14b constituting the hinge portion of the outlet are arcuate is set to 560 mm as an example, but a force in the closing direction is obtained after opening the first flap portion. Therefore, the thickness is preferably about 300 to 760 mm. If this radius of curvature 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 addition, the example different from FIG. 1 of the cut line 11 provided in the extraction opening of this invention is shown in FIG.5, FIG.6, FIG.7. FIG. 5 is an example in which the perforated cut line is replaced with a zipper, and FIG. 6 is an example in which only one cut line is provided at the center of the outlet, and FIGS. b) is an example in which two sets of cut lines in which the perforated cut lines are constituted by double lines are provided. In the example of FIGS. 7A and 7B, a zipper is provided at one end of the strip-shaped cut portion sandwiched between two sets of double wires. 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 are all examples of the cut line of the present invention.
FIG. 7 (b) shows two perforations having incisions with different lengths on both sides of the strip-shaped cut portion 13 in parallel, and each perforation has a staggered pattern. The perforation having a long cut portion is located inside the carton, and the perforation having a short cut portion is located outside the carton. If these two types of perforations with different lengths of cuts are arranged in a zigzag pattern, when the strip-shaped cut part is picked up with a finger and cut out, an uneven cut is formed along the perforation, so that it looks good. Well, the edge of the band-shaped cut-out part does not fluff or flutter, and it does not become a non-uniform jagged cut surface, so the appearance is good. Further, when the strip-shaped cut portion 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-layer white paperboard mainly composed of waste paper, the edge of the strip-shaped cut-out portion can be cut out relatively smoothly as described above, so printing and color were applied. 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 with different lengths on both sides of the strip-shaped cut portion 13 is arranged in a staggered manner. Since the cut portion of the outer perforation is formed to be long and short, when the strip-shaped cut portion is cut, the edge of the strip-shaped cut portion is beautifully cut into irregularities, so that the appearance of the cut is improved.

In this case, as shown in FIG. 7 (c), the length d of the long perforated cut portion m is preferably 1 to 6 mm, and the length e of the short perforated cut portion n is 0. Preferably, the ratio d / e between the length d of the long perforation and the length e of the short perforation is in the range of 1.2 to 12. It is preferable. If the length and ratio of the two perforated cuts are within this range, the strip-shaped cut part can be cut easily and cleanly. When the lengths of the long perforated portion m and the short perforated portion n are less than 1 mm and less than 0.5 mm, respectively, it becomes difficult to cut the strip-shaped cut portion, and the long cut portion m and the short cut portion When the length of n becomes longer than 6 mm and 3 mm, respectively, the strength of the strip-shaped cut portion is lowered, and the strip-shaped cut portion is easily broken by an impact during transportation or storage. Further, when the d / e ratio is less than 1.2, it becomes difficult to cleanly cut the strip-shaped cut portion. When the d / e ratio exceeds 12, the strength of the strip-shaped cut portion is reduced, and the impact during transportation or storage is reduced. As a result, the strip-shaped cut portion is easily broken.
Moreover, it is preferable that the space | interval i of the notch parts m and n of two perforations is 0.2-1 mm. When the interval i between the notches m and n of each of the two perforations is less than 0.2 mm, the strength of the strip-shaped cut portion is lowered, and the strip-shaped cut portion is easily broken by an impact during transportation or storage, When it becomes longer than 1 mm, it becomes difficult to cut the strip-shaped cut 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 the length e of the cut portion n having the short cut portion n. The distance g (the length of the connecting portion) between adjacent notches n in the perforation having a short notch n is the same length, and the notch of the perforation having a long notch m It is preferable that the lengths m of the two perforations are set in a zigzag pattern by setting the length to be approximately the same as the length d of m. You may comprise so that it may have some overlap allowances by adjusting the length of an insertion part. It is preferable that the distance h (length of a joint part) between the adjacent cut parts m in the perforation which has a long cut part m is 0.5-3 mm, and the perforation which has the short cut part n It is preferable that the distance g (length of a connection part) between the adjacent notch parts n is 1-6 mm.
Moreover, it is preferable that the width f of the notches m and n of each perforation is 0.5 to 3 mm.

  FIG. 9 shows an example different from those shown in FIGS. 1, 5, 6, and 7, in which the knob 31 is formed by providing the knob-like folding line 30 on the band-like cutout 13 of the tissue paper outlet. This is a modification of the carton. Further, in this example, unlike the examples of FIGS. 1 and 5 to 7, the curved cut lines 15 a and 15 b and the end cut lines 12 a and 12 b are discontinuous cuts having a connecting portion (connecting portion). Consists of incoming lines. The other example of FIG. 1 is an example in which these score lines are constituted by continuous score lines. Further, this example (FIG. 9) shows an example in which the outlet is provided only on the upper surface plate, unlike the example of FIG. 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 arc-shaped cut line connected to the end of the hinge portion of the first flap. .

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, there is one opening cut line 11 in the upper surface opening. In case of, press with your finger. When the strip-shaped cutout portion 13 is arranged, either the left or right second flap portion 17 is pushed down from the fold line 18, and a finger is put under the end of the cutout portion 13 to pinch the cutout portion and cut off. Thereafter, when the uppermost tissue paper is picked up from the opened portion and pulled upward, the pair of first flap portions 16 and 16 are inclined obliquely upward along the curved folding lines 14a and 14b bulging outward. While bending. In this case, as shown in FIG. 9, when the knob portion folding line 30 is arranged in the vicinity of the end of the strip-shaped cutout portion 13 so as to be substantially orthogonal to the opening cut lines 11 a and 11 b, and the knob portion 31 is formed, It is preferable because it is easy to open.
Further, the next tissue paper is drawn out from the opened portion, and between the opposing sides of the pair of first flap portions, between the opposing sides of the first flap portions and the second flap portion, and a box. Are held in a pop-up state by being elastically sandwiched between the opening edges.
Further, the pair of first flap portions 16 and 16 is formed so that the folding lines 14a and 14b serving as hinges have an arc shape that bulges toward the outside on the long side of the upper surface of the carton. When closing, a tendency to close (force to return to the state before bending) works. For this reason, while the tissue paper being taken out is elastically sandwiched between the pair of first flap portion and second flap portion and held in a predetermined position in the opening portion, even if the tissue paper content decreases, Prevent tissue paper from falling into the carton. When the tissue paper is not taken out, the first flap part acts as a lid 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 is reduced, as shown in FIG. 8, the pair of first flap portions provided at the outlet of the bottom plate can be bent and used as a bottom raising member. . That is, when the two first flap portions 10 in the lower surface outlet 10b are bent approximately 90 degrees inside the carton and the internal tissue paper is pushed up to the upper surface side, this causes the upper surface of the tissue paper 10 Can be popped up stably.

Further, in this embodiment (example in FIG. 1), the tissue paper outlets are provided on the two opposite surfaces (upper surface and lower surface) of the carton, so there is no discrimination between the upper and lower surfaces of the carton, and how to place the carton during use However, as shown in FIG. 11, both horizontal installation and vertical installation can be used, so that it can be used in a narrow place. Further, since the tissue paper can be taken out from both the upper and lower surfaces, even when the remaining tissue paper is reduced, the take-out property of the tissue paper is improved.
In addition, when opening the carton, it is necessary to consider the material of the carton in order to prevent the band-shaped cut portion 13 from being broken or causing a break in the peripheral portion 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 has the first flap and the second flap at the outlet, and since the opening is large, there are few portions where the tissue touches at the outlet of the carton, and the opening shape is smooth. When opening and taking out one tissue at a time, (1) The sound when taking out the tissue is almost as low as a conventional carton with film. (2) Little paper dust is generated when removing tissue.

In general, cartons containing sanitary paper such as tissue paper are sold in the market, with a plurality of (usually 5 units in one unit) accumulated in one pack and the surroundings wrapped in film. It is convenient for the user if a carton stand member is built in the packaging pack. The stand member may be manufactured separately from the carton using cardboard. For example, the stand member may be manufactured from the bottom plate of one of the five cartons. 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 the structure of the outlet or the carton having the outlet on both upper and lower sides. You are not limited to what you do. In addition, an adhesive, a magnet, or the like may be provided on the back surface of the stand member and used by attaching to a refrigerator, a kitchen cabinet, a table wagon, an office desk, or an automobile dashboard. FIG. 12 is a developed view showing an example in which a stand member is integrally incorporated in the lower surface plate 2 of the carton of the present invention. FIG. 13 is an explanatory view of a method of assembling the stand member S cut from the lower surface plate 2 of FIG.
