Description

  The present invention relates to a sanitary paper storage carton, and more particularly to a sanitary paper storage carton that can easily peel off a window film.

  In general, tissue paper widely used in homes and offices is sold in the form of being stored in the internal space of a rectangular parallelepiped box (hereinafter also referred to as “carton”). When using tissue paper, the user cuts the elongated outlet on the box by cutting off a perforation (cutting line for forming the outlet) of a predetermined shape provided on one side of the box (usually the upper surface of the box). Can be formed.

  The tissue paper stored in the box is usually a pair of two sheets, and each pair is stored by being alternately folded by a so-called pop-up method so that each set can be continuously taken out from the inside of the box. ing. Thus, when alternately folded, when one set of tissue paper is pulled out from the slit, the next set is pulled out from the inside of the box to the position held by the slit. The pulled-out tissue paper is held in a predetermined position where it pops up by the frictional force between the slit of the window film and the tissue paper, and is prevented from falling into the box. In addition, tissue paper is protected from external dust and foreign matter by a window film.

  Such a box is not limited to tissue paper, but is used to store sanitary paper that includes tissue paper (a collective term for disposable paper such as paper towels (kitchen paper, etc.), toilet paper (excluding rolls), and cotton (paper cotton)). Widely used as a box.

  By the way, the “Container Recycling Law” has been fully implemented since 1997, and it has clarified the responsibility of consumers to separate and collect waste, municipal collection, and the recycling of businesses. As a result, in recent years, the movement toward building a recycling-oriented economic society has been accelerating. As for used cartons of sanitary paper such as tissue paper and kitchen paper, consumers are required to peel off the pasted window film from the carton body, separate it, and discard it.

  As such a box, for example, a box in which a window film such as a polyethylene film covering the outlet is previously attached from the inside of the box and a linear slit is formed at the center of the window film is proposed. (For example, refer to Patent Document 1). The user can draw out the tissue paper stored in the internal space through the slit of the window film and use it. And the adhesion | attachment part at the time of sticking a window film on a box is arrange | positioned in the rectangular shape which surrounds an extraction port in many cases.

  Conventional sanitary paper storage cartons are generally formed continuously without breaking the portion of the bonded portion disposed along the slit forming direction. Therefore, when the window film 20 (for example, FIG. 11 and FIG. 12 of the present application) is peeled along the long side direction, a large force is required particularly at the start of the peeling, so that the peeling is difficult. was there. Therefore, in the case where the bonding portion has such a rectangle, sanitary paper storage cartons having a shape in which a part of the short side of the rectangle is broken have been proposed (for example, Patent Document 2 and Patent Document). 5).

  For example, in the sanitary paper storage carton 110 shown in FIG. 11 of the present application, at least a part of the rectangular adhesive portion 22 arranged along the slit forming direction is broken and formed discontinuously. This is an example. However, this carton is formed by discontinuously forming a part of the adhesive part for the purpose of preventing a malfunction when the slit formed in the paper window film is broken from the end part. It is not intended to reduce the bonding strength of the bonded portion.

  Further, when the window film is peeled off, it is often peeled along the longitudinal direction of the window film (or the long side direction of the rectangle if the window film is formed in a rectangular shape). For this reason, the effect of easily peeling off the window film is exhibited only by forming the adhesive portions discontinuously along the peeling direction. That is, as in the sanitary paper storage carton 110 shown in FIG. 11 of the present application, when the discontinuous part 24 is formed in a part of the rectangular short side of the rectangular adhesive part 22, the rectangular adhesive part Although it is possible to reduce the adhesive strength to some extent as compared with the case where all of the above are continuously formed, the window film cannot always be easily peeled off with a weak tensile force.

  In view of this, various ideas have been proposed to make it easy to peel off the pasted window film from the carton body and to facilitate separation and disposal of the window film. For example, a collaborator of the present inventor has already proposed a carton in which a cut line surrounding a bonding portion of a window film is formed in the carton body (see, for example, Patent Document 3).

Furthermore, various devices have been made for the adhesive portion. In the sanitary paper storage carton 120 shown in FIG. 12 of the present application, the adhesive portion 22 is formed in a rectangular shape surrounding the outlet, and the long side of the rectangle This is an example in which the width W1 of at least a part of the bonded portion formed in is formed narrower than the maximum width W2 of the short side of the rectangle. The applicant of the present application has proposed that the adhesive portion is partially broken or a narrow portion is arranged to facilitate peeling (see Patent Document 4).
Japanese Utility Model Publication No.41-6464 JP-A-9-118377 JP-A-2005-313909 Japanese Patent Application No. 2006-41217 JP 2004-217296 A

  In particular, the sanitary paper storage carton 130 shown in FIG. 13 proposed by the present applicant in Patent Document 4 is an example in which the adhesive portion is partially broken or the narrow portion 56 is formed. The user can peel off the window film from any direction starting from the four vertices of the rectangular film.

  However, as shown in FIG. 13, the adhesive strength can be reduced by providing a narrow portion 56 in a part of the adhesive portion 22, but it was used as an adhesive when an elderly person peeled off with a weak force. There was a phenomenon that the film was torn or stretched without the vinyl being peeled off. As in the present application, even a person who has a weak force by forming a non-adhesive portion has not been configured to be easily and easily peeled off. It was anxious to be able to peel off the window film more easily.

  The present invention has been made in view of such problems of the prior art, and even if the force to peel off is weak, such as an elderly person, a child, or a woman, the window film is removed from the carton body. It is an object to provide a carton for storing sanitary paper that can be easily and reliably peeled off even with a weaker force.

As a result of intensive studies to solve the above-mentioned problems, the present inventor has as follows: 1) an adhesive portion of the window film is provided so as to surround the outlet, and the overall shape is formed in a hexagonal frame shape; 2) A pair of adhesive portions provided opposite to each other via the outlet, and another pair of adhesive portions provided opposite to each other via the outlet, 3) the pair 4) The adhesive part of the V-shaped adhesive part that gradually spreads in the direction of the central part of the outlet is paired. 4) The other pair of adhesive parts has the outer shape of the upper surface of the carton body. It is assumed that the linear adhesive portions provided on the sides of the rectangle formed are paired, and 5) the V-shaped adhesive portions constituting the pair of adhesive portions and the other pair of adhesive portions. The linear adhering part that constitutes is independent through at least one discontinuous part. It has been found that the force required for peeling off can be further reduced, and the present invention has been completed. That is, according to the present invention, the following sanitary paper storage carton is provided.

Should be.

[1] Carton for storing sanitary paper:
The sanitary paper storage carton of the present invention has a shape having an upper surface 2, a bottom surface 4, a pair of side surfaces 6, and a pair of wife surfaces 8, as in the sanitary paper storage carton 1 shown in FIGS. 1 and 7, for example. The cut-out line 14 for forming the outlet is formed so as to form a box that is bent and defined by these surfaces and has an internal space in which the sanitary paper can be stored. A window film having a formed carton body 16 and a window film 20 which is disposed so as to cover the outlet from the inside of the carton body 16 and has a slit 18 for taking out sanitary paper. 20 is affixed to the inside of the carton body 16 by the adhesive portion 22 is provided in a form surrounding the preparative adhesive section 22 outlet, the shape of the entire A pair of adhesive portions 22a which are formed in a rectangular frame shape and are provided opposite to each other via an outlet, and another pair of adhesive portions 22b which are provided opposite to each other via an outlet. The pair of adhesive portions 22a is paired with a V-shaped adhesive portion that gradually spreads toward the center of the outlet, and the other pair of adhesive portions 22b is the outer shape of the top surface of the carton body 16. A linear adhesive portion provided on the side of the rectangular side forming a pair forms a V-shaped adhesive portion constituting a pair of adhesive portions 22a and a linear shape constituting another pair of adhesive portions 22b the adhesion portion, are provided independently through the discontinuous portion of the at least one location.

[1-1] Carton body:
The "carton body" is an inner space that can be folded into a shape having an upper surface, a bottom surface, a pair of side surfaces, and a pair of wife surfaces having a take-out port, and can store sanitary paper. And a box having a cut-out line for forming an outlet so as to coincide with the outer peripheral shape of the outlet of the sanitary paper.

[1-1A] Box shape:
The “box shape” is an inner space that can be folded into a shape having a top surface, a bottom surface, a pair of side surfaces, and a pair of wife surfaces having a take-out port, and can store sanitary paper. Shape. Examples of such shapes include hexahedron shapes such as a rectangular parallelepiped shape and a cubic shape. In these shapes, the upper surface and the bottom surface, the one side surface and the other side surface, and the one wife surface and the other wife surface are arranged in parallel so as to face each other. Among these shapes, a rectangular parallelepiped shape is preferable. For example, the sanitary paper storage carton 1 shown in FIGS. 1 and 7 is an example in which the carton body 16 is configured in a rectangular parallelepiped shape having the side surface 6 side of the carton body 16 as a long side and the end surface 8 side as a short side. In addition, in these shapes, those obtained by chamfering the ridge line portions of the two surfaces are also included in the “box shape” referred to in this specification.

  The “carton main body” is formed into a shape having a top surface, a bottom surface, a pair of side surfaces, and a pair of wife surfaces having an outlet, for example, by bending a carton blank made of a paper material or the like. The carton blank 100 shown in FIG. 8 has a top surface 2, a bottom surface 4, and a pair of side surfaces 6 formed of a sheet of paper material via a folding line, and from the edge of the side surface 6 via the folding line. The inner flap 26 is extended.

  Further, an upper outer flap 28 extends from the edge of the upper surface 2 via a fold line, and similarly, an outer bottom flap 30 extends from the edge of the bottom surface 4 via a fold line. Has been issued. Further, a side joining margin 32 is extended from one side edge of the bottom surface 4 via a fold line, and the end face of the bottom surface outer flap 30 has a mating surface which is a joining margin with the upper surface outer flap 28. A joint 34 is attached. Such a carton blank 100 forms a pair of end faces 8 by bending each fold line, joining the side joining margin 32 and the side face 6, and joining the end face joining margin 34 and the upper outer flap 28. be able to. By doing so, the carton blank 100 can be a sanitary paper storage carton 1 as shown in FIGS. 1 and 7.

  In the sanitary paper storage carton of the present invention, the carton body is formed on the bottom surface, and two points a and b on a ridge line between the bottom surface and one side surface (hereinafter referred to as “bottom surface-side surface ridge line”). A first incision line for connecting the bottom surface and the side surface ridge line and / or one side surface, and starting from two points a and b, the bottom surface side surface ridge line end point or the ridge line between the top surface and the side surface ( Hereinafter, it is preferable that the first cutting line for dismantling reaching “upper surface-side surface ridge line” is formed.

  Such a carton can be easily disassembled by separating the side surface and the bottom surface when discarding an empty carton after use. Combined with the effect that “the carton can be easily disassembled” and the effect of “the window film is easy to peel off” of the sanitary paper storage carton of the present invention, the carton is disassembled and the window film is pulled. A series of operations of peeling off becomes easier and simpler. Therefore, such a carton contributes to promoting the separation and disposal of the sanitary paper storage carton.

  For example, the sanitary paper storage carton 1 shown in FIG. 7 includes a first push-in cutting line 38 formed on the bottom surface 4 and connecting the two points a and b on the bottom surface-side ridge line 36. This is an example in which a first dissection cut line 44 formed on the bottom surface-side ridge line 36 and starting from two points a and b and reaching the end point 40 of the bottom surface-side surface ridge line 36 is formed.

  Further, the sanitary paper storage carton of the present invention further includes an upper surface outer flap that extends from the edge of the upper surface via a ridge line, and a bottom surface outer flap that extends from the edge of the bottom surface via the ridge line. The upper surface outer flap and the bottom surface outer flap are joined to form a wife surface, and the bottom surface outer flap is provided with a joint allowance with the upper surface outer flap at the tip, and the joint margin and the bottom surface outer flap are A second cutting line for dismantling is formed between the second cutting line formed on the bottom surface and connecting two points on the ridgeline between the bottom surface and the one end surface, and a flap outside the bottom surface It is further preferable that a third dismantling cut line that is formed at the two points and reaches the second dismantling cut line is formed.

  Such a carton can separate not only the side surface and the bottom surface, but also the upper surface outer flap and the bottom surface outer flap forming the wife surface. Therefore, the carton can be further easily disassembled and developed into a planar shape, and the carton can be easily dismantled even by an elderly person or a disabled person. That is, in combination with the structure of the joint portion of the sanitary paper storage carton according to the present invention, the window film can be more easily peeled off, and the paper and plastic can be separated and discarded more easily. .

  For example, the sanitary paper storage carton 1 shown in FIGS. 1, 7, and 8 includes an upper surface outer flap 28 that extends from the edge of the upper surface 2 via the ridge line, and an edge of the bottom surface 4 that passes through the ridge line. And an extended bottom outer flap 30. The bottom surface outer flap 30 is provided with a mating surface joint allowance 34 which is a joint allowance with the upper surface outer flap 28 at the tip, and the upper surface outer flap 28 and the bottom surface outer flap 30 are joined via the wife surface joint allowance 34. Thus, the end face 8 is formed, and a second dismantling cut line 46 is formed between the end face joining margin 34 and the outer bottom flap 30. Further, the carton body 16 is formed on the bottom surface 4, and has a second pushing cut line 48 connecting the two points c and d on the ridge line between the bottom surface 4 and the one end surface 8, and the bottom surface outer flap 30. This is an example in which a third dismantling cut line 50 that is formed and starts from two points c and d and reaches the second dismantling cut line 46 is formed.

  The sanitary paper storage carton 1 shown in FIGS. 1 and 2 can be disassembled by the method shown in FIGS. First, as shown in FIG. 9, when the inner portion of the second push-in cutting line 48 is pressed and broken with the thumb, the third dismantling cut line 50 and the second dismantling cut-off line are accompanied accordingly. The cut line 46 is also broken, and the upper outer flap 28 and the lower outer flap 30 can be cut. Next, when the inner portion of the first push-in cut line 38 is pressed and broken with the thumb, the first break-up cut line 44 is also broken and the bottom surface 4 and the side surface 6 are cut. be able to.

  By doing so, the upper outer flap 28, the lower outer flap 30, the side surface 6 and the bottom surface 4 can be cut outward, and the sanitary paper storage carton 1 is developed in a flat shape as shown in FIG. Can be dismantled to state. In this state, the window film 20 can be peeled off very easily.

  The sanitary paper storage carton of the present invention has an inner space defined by an upper surface, a bottom surface, a pair of side surfaces, and a pair of wife surfaces having an outlet. This internal space is a space for storing sanitary paper. There are no particular restrictions on the type of sanitary paper stored in this internal space. For example, tissue paper (what is called facial paper, decorative paper, etc.), dust paper, paper towels (kitchen paper, etc.), toilet paper (excluding rolls), Disposable paper such as Watting (paper cotton) (for example, see Paper and Pulp Technology Handbook 5th Edition, page 459, issued on January 30, 1992, edited and published by the Pulp and Paper Technology Association).

  Among them, one sanitary paper is folded and folded while the other sanitary paper is sandwiched between the folded parts, so that a bundle of sanitary paper in which a plurality of sanitary papers are continuously stacked is stored in the internal space. It is preferable to do. In the sanitary paper having such a laminated structure, when the uppermost sanitary paper is taken out, a part of the sanitary paper of the next layer sandwiched between the sanitary papers protrudes from the outlet, and the sanitary paper can be easily taken out. There is an advantage (so-called pop-up method).

  There is no particular limitation on the material constituting the sanitary paper storage carton of the present invention. However, it is preferable to use a paper material such as cardboard as a constituent material for the convenience of bending the box. Generally, as these paper materials, for example, those produced using wood pulp, waste paper, etc. as raw materials can be suitably used.

[1-1B] Cut-out line for forming an outlet:
The “takeout forming cut line” is a cut line formed so as to coincide with the outer peripheral shape of the sanitary paper takeout opening. The user can form the outlet by breaking the cut line, and can take out the sanitary paper from the outlet.

  There is no restriction | limiting in particular about the outer periphery shape of the taking-out opening of a sanitary paper, What is necessary is just to select suitably according to the shape of a carton main body or a sanitary paper. However, since a rectangular parallelepiped is often used as the carton body, the shape of the outlet is preferably a horizontally long shape along the longitudinal direction of the carton body. Accordingly, examples of the outer peripheral shape of the outlet include a substantially rectangular shape, a substantially oval shape, an oval shape, a rhombus shape, and a polygonal shape. For example, the sanitary paper storage carton 1 shown in FIG. 1 is an example in which a substantially rectangular outlet forming cut line 14 is formed.

  The cut line for forming the outlet is usually formed on the upper surface 2 of the carton main body 16 like the sanitary paper storage carton 1 shown in FIG. 1, but there is no particular limitation. For example, it may be formed on the bottom surface of the carton body, or may be formed on another surface. Moreover, the cut line for forming the outlet does not have to be formed only on one surface, and may be formed on two or more surfaces (for example, an upper surface and a bottom surface).

  In addition, the cut line for peeling may be formed in the part (part used as a cut piece) enclosed by the cut line for opening formation so that two points of the cut line for outlet formation may be connected. By forming such a cut line, there is an advantage that the cut piece can be easily peeled off. For example, the sanitary paper storage carton 1 shown in FIG. 1 is an example in which a substantially U-shaped tearing cut line 52 is formed on the end side of the substantially rectangular outlet forming cut line 14. .

  The above-described cut line for outlet and peel-off line may be a straight cut (slit) or may be a perforation having a partial connection. In addition, a break line for opening, which is called a zipper in the packaging industry, is bent into a bowl shape (see page 281 of the packaging industry well-known and commonly used technology, issued on December 20, 1978), 2 A perforated line may be used. For example, the sanitary paper storage carton 1 shown in FIG. 1 is an example in which a portion of the outlet forming cut line 14 inside the tearing cut line 52 is a double line perforation.

  Moreover, in the sanitary paper storage carton of the present invention, it is also one of preferable modes to form a push-up piece forming cut line for forming a pair of push-up pieces on the bottom surface. When the remaining amount of sanitary paper stored in the carton body is low, the push-up piece forming cut line formed on the bottom surface is pressed and broken, and folded inside the carton body to remove the pair of push-up pieces. Form. Since the sanitary paper inside the carton body is pushed upward by the push-up piece, it is possible to stably pop up from the outlet on the top surface to the last sheet of sanitary paper. For example, the sanitary paper storage carton 1 shown in FIG. 7 is an example in which a pair of U-shaped push-up piece forming cut lines 54 are formed at the center of the bottom surface 4.

[1-2] Window film:
The “window film” is a film material that is disposed so as to cover the take-out port from the inside of the carton body and in which a slit for taking out sanitary paper is formed. When a window film is pasted from the inside of the outlet, the sanitary paper can be protected from external dust and foreign matter. Also, when taking out sanitary paper, the pop-up sanitary paper is prevented from falling into the carton due to friction between the slits formed in the window film, and the sanitary paper is kept protruding from the outlet. It becomes possible to do.

[1-2A] Film:
A “film” is a thin film member. The constituent materials are not particularly limited, but for example, plastics such as polyethylene, polypropylene, polyvinyl chloride, polyester, polyvinyl alcohol; printing paper such as glassine paper, kraft paper, Kent paper, India paper, calligraphy paper, wrapping paper, processed base paper And the like can be suitably used. Further, as the plastic, a biodegradable plastic may be used.

  The “biodegradable plastic” means a plastic that is decomposed by the action of microorganisms including bacteria or enzymes. Specifically, poly (α-hydroxy acid) such as polyglycolic acid and polylactic acid; polylactones such as poly (ε-caprolactone) and poly (β-prochiolactone); poly-3-hydroxypropionate, Poly-3-hydroxybutyrate, poly-3-hydroxycaprolate, poly-3-hydroxyheptanoate, poly-3-hydroxyoctanoate, poly-3-hydroxyvalerate, poly-4-hydroxybutyrate Poly (α-hydroxyalkanoate) such as polyethylene oxalate, polyethylene succinate, polyethylene adipate, polyethylene azelate, polybutylene oxalate, polybutylene succinate, polybutylene adipate, polybutylene sebacate, polyhexamethylene seba Kate, polyneopentylo Polycondensate of glycol and carboxylic acid such as Sareto; and the like. The polymer constituting these plastics is not limited to a homopolymer and may be a copolymer. Moreover, the polymer which has a urethane bond, an amide bond, an ether bond, etc. may be used in the range which does not affect biodegradability.

  The film includes any of a transparent film, a translucent film, an opaque film, and a colored film. Moreover, the film on which the character, the pattern, etc. were printed may be sufficient. The shape of the film may be any shape as long as the outlet of the carton body can be covered. However, since a horizontally long shape is widely used as the shape of the outlet, it is preferable to use a rectangular film like the sanitary paper storage carton 1 shown in FIGS. Therefore, in the following description, the description will be made by an aspect using a rectangular film corresponding to a horizontally long shape which is a shape of a frequently used outlet.

  In the sanitary paper storage carton of the present invention, the window film is configured in a rectangular shape, and has a higher tensile strength in the long side direction than the tensile strength in the short side direction. Is preferably affixed to the inside of the carton body so that the long side is along the side surface and the long side is along the side surface.

  For example, in a stretched film obtained by stretching a plastic made of a linear polymer such as polyethylene or polypropylene in a certain direction, the molecular chain is oriented in the stretching direction of the linear polymer, so that the tensile strength in the stretching direction is increased. When such a stretched film is used for a window film, the window film 20 is configured in a rectangular shape like the sanitary paper storage carton 1 shown in FIG. When the inner side of the carton main body 16 is pasted so that the long side is along the side surface 6, the window film 20 is peeled off from the one end face 8 side toward the other end face 8 side. It can be peeled off neatly without breaking.

[1-2B] Slit:
A “slit” is a break through the window film. Sanitary paper such as tissue paper stored in the sanitary paper storage carton is drawn out of the carton through this slit. For example, the sanitary paper storage carton 1 shown in FIG. 1 is an example in which a linear slit 18 is formed at the center of the window film 20.

[1-3] Bonding part:
The “adhesion part” is a part that adheres the carton body and the window film. That is, the window film is affixed to the inside of the carton body by the adhesive portion. As long as a window film can be affixed on a carton main body, the formation method is not specifically limited. For example, the adhesive portion can be formed by a method such as an adhesive, a double-sided tape, and heat fusion. In addition, the adhesion part may be colored. For example, by forming a bonded portion using a colored adhesive or the like, there is an advantage that the position of the bonded portion can be easily visually recognized and the manufacture of the carton is facilitated.

In the sanitary paper storage carton of the present invention, the adhesive portion is provided so as to surround the outlet, and the overall shape is formed in a hexagonal frame shape, and relative to the outlet via the outlet. A pair of adhesive portions provided facing each other and another pair of adhesive portions provided opposite to each other via the outlet, and the pair of adhesive portions is a central portion of the outlet V-shaped adhesive portions that gradually spread in the direction (a divergent shape) form a pair, and the other pair of adhesive portions is a linear shape provided on the side of the rectangle that forms the outer shape of the top surface of the carton body. The bonding portions form a pair, and the shape of the entire bonding portion surrounding the outlet is formed in a hexagonal shape. By comprising in this way, the force required at the time of peeling can be reduced significantly.

The adhesive portion includes a V-shaped adhesion portion constituting the pair of adhesive regions, a linear bonding part constituting the other of the pair of adhesive regions through discontinuities of at least one portion It is provided independently . At least by making this discontinuous part exist, peeling becomes easier.

Of the adhesion portion, the pair of adhesive regions, provided on the short side of the rectangle forming the outer shape of the carton body top surface, and the other pair of bonded joints, long side of the rectangle forming the outer shape of the carton body top surface It is preferable to provide it in order to reduce the force required to peel off. Furthermore, it is preferable that the pair of bonded portions have discontinuous portions formed at a V-shaped opening start point (hereinafter also referred to as a start point) of the V-shaped bonded portion constituting the pair of bonded portions . For example, the sanitary paper storage carton 1 shown in FIGS. 2 to 3 is a specific arrangement example of the bonding portion 22. In addition, the size of the discontinuous portion 24 formed in the embodiment shown in this drawing can be sufficiently resisted by the force applied to the window film when the sanitary paper is taken out, and can be easily peeled off by the desired peeling force. Just choose.

  The spreading angle of the adhesive portion formed in a V shape may be set to an angle that can sufficiently counter the sanitary paper take-out pressure and can be smoothly peeled off. Of course, it goes without saying that it is necessary to consider the balance with the length of the bonded portion formed on the long side. Usually, it is arbitrarily selected from a range of 60 ° to 120 ° when expressed as a full angle. The V-shaped bonded portion is preferably provided with a discontinuous portion that becomes the non-bonded portion 23 at least at the starting point, preferably including the vicinity thereof.

In addition, in the sanitary paper storage carton of the present invention, various aspects of the shape of the discontinuous portion formed as at least the starting point of the V-shaped bonded portion and the non-bonded portion 23 provided in the vicinity thereof are shown in FIGS. Shown in FIG. 4C. Specifically, since the bonding portion 22a has a width W, the cut shape with respect to the width W is various in relation to the outer shape of the top surface of the carton body, in other words, the rectangular short side forming the outer shape of the window film. It can be a cut shape. Specifically, a part of the hexagonal frame-shaped adhesive portion is cut out in parallel with the rectangular short side forming the outer shape of the window film (FIG. 4A), or the rectangular short side forming the outer shape of the window film. A part of the hexagonal frame-shaped adhesive part is formed so as to be cut perpendicularly to the vertical direction (FIG. 4B), or a predetermined angle, for example, 30 ° to the rectangular short side forming the outer shape of the window film. You may form with the arbitrary angles within 60 degrees (Drawing 4C). In addition, you may form from the some discontinuous part formed in barcode form or dotted line form.

  By taking the various shapes described above, the force required for peeling at the start of peeling can be reduced compared to the conventional one, and this part is centered along the peeling direction. By applying the adhesive in a V-shaped shape that gradually spreads toward the surface, the peeling force reduces the peeling resistance that occurs when the adhesive is applied vertically as in the past. Furthermore, in order to guide the force at the start of peeling to the force in the long side direction substantially without resistance, a rectangular portion that forms the outer shape of the window film by grasping a portion of the window film that faces the non-adhesive portion 23. The window film can be peeled off very easily in a direction parallel to the long side (parallel to the slit forming direction). Although not shown in the figure, characters indicating the starting point of peeling such as “please pull from here” may be printed on the surface of the carton body near the non-bonding portion 23.

  For example, in the sanitary paper storage carton 1 shown in FIGS. 2 to 3, the bonding portion 22 is formed with a non-bonding portion 23 at the start point of the so-called “V-shaped” bonding portion. The size of the adhesive portion 23 is such that the window film is not peeled off or greatly distorted by the force applied when the sanitary paper is taken out, and has an area that can suppress the force required for peeling as much as possible. Just do it.

Furthermore, in the sanitary paper storage carton of the present invention, the discontinuous portion 24 is formed on at least a part of the other pair of bonding portions 22b provided on the long side of the rectangle forming the outer shape of the upper surface of the carton body. It may be. With such a structure, reducing the adhesive strength of the amount corresponding to the adhesive portion of the formed discontinuous portion, namely, it is possible to reduce the area of the bonding portion to peel, the outer shape of the carton body top surface It is possible to easily peel off the window film along the long side direction of the rectangle formed (in other words, the slit forming direction ) , for example, along the long side direction of the rectangular window film. Therefore, even a weak person such as an elderly person, a child, or a woman can surely and easily peel off the window film from the carton body sufficiently even with a weak force. The size of the discontinuous portion 24 may be selected within a range that can sufficiently resist the force applied to the window film when the sanitary paper is taken out and can be easily peeled off by a desired force at the time of peeling.

For example, as shown in the sanitary paper storage carton 140 in FIG. 5, a part of the adhesive portion 22b arranged along the direction in which the slit 18 is formed is broken, and each of the discontinuous portions 24 at three locations (total of 6 locations). May be formed. Further, by forming a narrow portion 56 formed narrowly in a part of the adhesive portion 22b as shown in FIG. 6 to be described later, for example, the adhesive strength in the portion can be reduced. Therefore, the window film 20 can be easily peeled off as compared with the case where the bonding portion 22b is formed with a certain width.

  Furthermore, in the sanitary paper storage carton of the present invention, it is preferable that a discontinuous portion is further formed in at least a part of a portion of the adhesive portion that is arranged in a divergent shape in the slit forming direction. Such a configuration can reduce the peeling strength at the time of peeling while securing the necessary adhesive strength for the short side portion, so that the discontinuous portion is provided in the portion arranged along the slit forming direction. Combined with the structure to be formed, the window film can be peeled off more easily.

For example, in the sanitary paper storage carton 150 shown in FIG. 6, the adhesive portion 22 is disposed so as to surround the outlet, and a part of the adhesive portion 22 b disposed along the direction in which the slit 18 is formed is broken. , together with the discontinuity 24 is formed in each three (total of six), a part of the adhesive portion 22b formed between the discontinuity 24, which is narrower than the width of the other partial width This is an example in which a narrow portion 56 is formed. Further, in this example, a taper portion 25 is formed in a portion of the adhesive portion 22a having a V-shape that is in contact with 22b arranged along the formation direction of the slit 18, and the V-shape is formed. When the non-adhesive part formed by discontinuous part of the adhesive part 22a is included in the discontinuous part and counted, seven discontinuous parts 24 (total of 14 parts) are formed. .

As the sanitary paper storage carton of the present invention, among the adhesive portions, among the adhesive portions 22a arranged in a V shape toward the slit forming direction and the adhesive portions 22b arranged parallel to the slit forming direction, Either one may be formed narrower than the other. Even in such a form, similarly to the form in which a part of the adhesive portion is discontinuous, the adhesive strength at that part can be reduced. Therefore, the window film can be peeled off very easily as compared with the case where the adhesive portion is formed with a certain width.

  Although not shown in the drawings, a form in which a part of the adhesive part arranged along the slit forming direction is broken to form a discontinuous part, and a part in which a part of the adhesive part is formed to be narrow. A combination of both is also a preferred embodiment. In such a form, it is possible to enjoy the effects of both a form in which a part of the adhesive part is discontinuous and a form in which a part of the adhesive part is narrowly formed, and the window film is peeled off more. It can be made easier.

  Although not shown, in the sanitary paper storage carton of the present invention, at least one end portion of the adhesive portion arranged along the slit forming direction is tapered. It is preferable to have a tapered portion. By setting it as such a structure, since an adhesion part becomes narrow as it goes to the front-end | tip of a taper part, the adhesive strength of the part can be reduced.

  In the sanitary paper storage carton of the present invention, the adhesive application area should be reduced to such an extent that it is not peeled off by the force applied when the sanitary paper is taken out and the force required for peeling can be suppressed as much as possible. Therefore, it is possible to shorten the drying time of the adhesive and reduce the amount of the adhesive used, which is preferable from the viewpoint of production efficiency, production cost, and resource saving.

  Conventionally, since it takes time for the adhesive to dry and exhibit adhesive force, there is a problem that the window film is peeled off before bonding unless the window film itself has a certain weight. On the other hand, in the sanitary paper storage carton of the present invention, the amount of adhesive to be used can be reduced, so that the drying time of the adhesive is shortened, and as a result, the window film is made thicker than necessary and the weight is reduced. Has the advantage that it is not necessary to increase the weight.

The sanitary paper storage carton of the present invention can be manufactured, for example, by the following manufacturing method. First, a pressing die having a convex surface that matches the desired shape of the bonded portion is prepared. Next, after the adhesive is attached to the convex surface of the pressing die, the pressing die is brought into contact with the position surrounding the cut line for forming the outlet of the carton blank, and the adhesive is attached to the carton blank. Further, before the adhesive is dried, a window film in which slits are formed in advance is placed at a predetermined position and attached.

  Thereafter, the carton blank is bent along the folding line, the side surface and the bottom surface are joined together, and the overlapping portion is bonded with an adhesive to form a square tube shape with the end face side open. Next, a purified paper bundle in which sanitary paper is laminated is loaded into the internal space of the rectangular tubular carton blank. Further, after bending the pair of inner flaps along the folding line, the upper surface outer flap and the bottom outer flap are folded so that the portions overlap each other, and the overlapping portions are bonded with an adhesive or the like, so that the pair of wife Form a surface. In this manner, the sanitary paper storage carton of the present invention can be manufactured.
