Description

  The present invention relates to a paper tube and a roll sheet using the paper tube.

  2. Description of the Related Art Conventionally, a toilet roll in which toilet paper is wound around a paper tube, in which a perfume is imparted to the paper tube, is known. In such a scented toilet roll, in addition to the scent of the scent during use, the perfume does not volatilize until the start of use (hereinafter referred to as scent retention).

  However, since toilet rolls are shipped after being manufactured and packaged in a packaging film made of polyethylene, polypropylene, etc., it takes a considerable amount of time to be used by consumers, so the scent becomes weak at the time of use. There was a problem.

  Therefore, for example, a perfume is interposed between the inner hollow cylinder and the outer hollow cylinder constituting the paper tube, and a plurality of perforations are provided in the inner hollow cylinder or the outer hollow cylinder, so that the scent at the initial stage can be obtained. A toilet roll with a scent that eliminates the shortcoming of insufficient volatilization and can always obtain a uniform volatilization effect is disclosed (for example, see Patent Document 1).

Japanese Patent No. 4159061

  However, in the toilet roll described in Patent Document 1, since the fragrance is interposed between the inner hollow cylinder and the outer hollow cylinder, volatilization of the fragrance until the start of use can be suppressed to some extent, but gradually. Since the perfume is volatilized, if the time until the consumer starts using the toilet roll is long, the scent becomes weak at the time of use.

  An object of the present invention is to provide a paper tube that prevents volatilization of the fragrance until the start of use and can start volatilization of the fragrance according to the intention of the consumer, and a roll sheet using the paper tube.

It is a perspective view of the roll-shaped toilet paper of this invention. It is the side view (a) and XX section sectional drawing (b) of the paper tube of this invention. It is sectional drawing (a) of the paper tube of this invention, and the one part enlarged view (b). It is explanatory drawing which shows the formation method of the paper tube of this invention.

  Hereinafter, a paper tube which is an embodiment of the present invention and a roll sheet using the paper tube will be described in detail with reference to the drawings. However, the scope of the invention is not limited to the illustrated examples.

(Embodiment)
In the present embodiment, toilet paper is illustrated as a sheet, and roll toilet paper is illustrated as a roll sheet.

<Rolled toilet paper>
For example, as shown in FIG. 1, the roll-shaped toilet paper 100 includes a paper tube 1, toilet paper 2 wound around the paper tube 1, and the like. A paper holder is provided in the paper tube 1. In general, the toilet paper 2 is pulled out and used with the support portion inserted.
Although the magnitude | size of the roll-shaped toilet paper 100 is not specifically limited, A thing with a diameter of 100-120 mm, a width of 100-115 mm, and a paper tube diameter of 35-50 mm is common, and it is suitable also in this invention.

  The base paper which comprises the toilet paper 2 can be manufactured with the papermaking raw material for thin paper which uses raw material pulp as a main raw material. The raw material pulp is not particularly limited, and an appropriate raw material pulp can be selected according to the specific application of the toilet paper 2 and can be used by appropriately blending.

In addition, the number of plies and the basis weight of the toilet paper 2 can be appropriately adjusted depending on the application, but the number of plies is 1 to 3 plies, the total paper thickness is 100 to 270 μm, and the basis weight per ply is 10 It is desirable to use one in the range of ˜30 g / m ² . When the basis weight is less than 10 g / m ² , it is preferable from the viewpoint of improving the softness, but it is difficult to ensure adequate strength that can withstand use. On the other hand, when the basis weight exceeds 30 g / m ² , the entire paper becomes hard and a feeling of stickiness is generated, resulting in poor touch. The basis weight is measured according to JIS P 8124 (1998).

  In addition, the paper thickness is measured by fully adjusting the specimen under the conditions of JIS P 8111 (1998), and then dial thickness gauge (thickness measuring instrument) “PEACOCKG type” (manufactured by Ozaki Seisakusho) under the same conditions. It shall be measured using Specifically, confirm that there is no dust, dust, etc. between the plunger and the measurement table, lower the plunger on the measurement table, move the memory of the dial thickness gauge to adjust the zero point, and then Raise the plunger, place the sample on the test bench, slowly lower the plunger and read the gauge at that time. At this time, just put the plunger. The terminal of the plunger is made of metal so that a circular plane having a diameter of 10 mm is perpendicular to the plane of the paper, and the load at the time of measuring the paper thickness is about 70 gf. Note that the paper thickness is measured with 1 ply for 1 ply, and with multiple plies for multiple plies. The measured value is an average value obtained by performing the measurement 10 times.

<Paper tube>
For example, as shown in FIG. 1, the paper tube 1 has a substantially hollow cylindrical shape.
FIG. 2 is a side view of the paper tube 1 and a cross-sectional view taken along the line XX. As shown in the side view of FIG. Is a spiral paper tube having a two-layer structure in which both the outer paper tube base paper 12 are spirally wound and bonded together with an adhesive.
Preferably, the spiral paper tube having a two-layer laminated structure in which the inner paper tube base paper 11 and the outer paper tube base paper 12 having a basis weight of 120 to 220 g / m ² and a paper thickness of 150 to 500 μm are spirally wound is a strength of the paper tube 1. Easy to secure.
For example, the solid lines indicated by JT21, JT22, and JT23 in FIG. 2A indicate the joint of the outer paper tube base paper 12 formed on the front side of the outer layer OL21 formed by spirally winding the outer paper tube base paper 12. The broken lines shown in JT24 and JT25 are the joint portions of the outer paper tube base paper 12 formed on the back side of the outer layer OL21 formed by spirally winding the outer paper tube base paper 12.
In FIG. 2 (a), the other non-numbered broken line is a joint portion of the inner paper tube base paper 11 formed on the inner layer IL21 formed by spirally winding the inner paper tube base paper 11.
Further, the inner layer IL21 and the outer layer OL21 constitute a paper tube layer LY21.

  2B, the paper tube 1 includes a paper tube layer LY21 formed of a hollow cylinder in which an inner paper tube base paper 11 and an outer paper tube base paper 12 are spirally wound. The capsule CP21 is provided on the inner peripheral surface of the paper tube layer LY21, and the fragrance is enclosed. The buffer CP21 prevents the capsule CP21 from being damaged and reduces the adhesion of the fragrance.

The capsule CP21 is made of gelatin or the like and contains a fragrance inside. Further, when the user crushes the capsule CP21 at the start of use, volatilization of the contained fragrance is started. The capsule CP21 preferably has a diameter of 4 mm or more so that it can be easily crushed during use. The film of the capsule CP21 is preferably 3 μm to 50 μm. Further, it is 5 μm to 20 μm under better conditions. When the thickness exceeds 50 μm, it is difficult for the user to crush the capsule CP21 although it is difficult to crush by external force. On the other hand, if it is less than 3 μm, it may be crushed by an unexpected external force, particularly when the capsule CP21 is applied to the outer paper tube base paper.
Although the manufacturing method of a fragrance | flavor capsule is not specifically limited, For example, if the dripping method is used, since the fragrance | flavor capsule which has a seamless film can be manufactured, it is preferable. This method can be performed by using a double nozzle and simultaneously discharging a fragrance-containing solution from the inner nozzle and a liquid coating material from the outer nozzle.
In addition to the fragrance, the capsule may contain other additives such as a solvent, a pigment, and an emulsifier. As a solvent for the fragrance-containing solution, for example, medium chain fatty acid triglyceride (MCT) can be used.
The coating can be used with, for example, starch, dextrin, polysaccharides, agar, duran gum, gelatin, carrageenan, various natural gelling agents, glycerin, various waxes, sorbitol, calcium chloride and the like, and further includes fragrances and coloring agents. You can also

The cushioning member CS21 is composed of a nonwoven fabric or the like, and covers the capsule CP21 to prevent the capsule CP21 from being crushed by an unexpected external force until it is used, and when the capsule CP21 is crushed and used, the capsule CP21 is stained. The fragrance | flavor taken out does not adhere excessively to the toilet paper 2, or it reduces that fragrance | flavor adheres to the support part of a paper holder. The buffer member CS21 may be a sponge type made of a synthetic resin such as polyurethane in addition to the nonwoven fabric.
When the buffer member CS21 is applied to the inside of the paper tube 1, the thickness of the buffer member CS21 is preferably 50 μm to 2000 μm. Moreover, it is 200 micrometers-600 micrometers in better conditions.
If the thickness is less than 50 μm, it will be crushed by an unexpected external force, or pain will occur when the user crushes. Conversely, if the thickness exceeds 2000 μm, the cushioning member CS 21 is particularly provided outside the paper tube 1. Depending on the particle size, the location of the capsule is difficult for the user to understand, or when it is applied inside, the roll is difficult to rotate smoothly when it is hung on the holder.
On the other hand, when the thickness is in the range of 200 μm to 700 μm, the location of the capsule is easy to understand, and even if it is crushed, it does not hurt. Hard to be crushed by external force. Moreover, as for the width | variety of the nonwoven fabric which is the buffer member CS21, 20 mm or more is desirable.
When the buffer member CS21 is provided inside the paper tube 1, if the width is shorter than 20 mm, the roll is difficult to rotate smoothly.
Even on the outside of the paper tube 1, if the width is short, there is a possibility that the buffer part will be deflated due to contact with other equipment such as when a paper tube conveying conveyor or paper is wound after the paper tube 1 is formed.
Although a manufacturing method is not limited, For example, a capsule can be bonded to a nonwoven fabric by the following method, and a paper tube can be shape | molded after that. That is, after an adhesive such as vinyl acetate is applied to the entire surface of the nonwoven fabric, capsules are applied to the bonding portion at regular intervals in the flow direction, and then bonded to the inner paper or outer base paper.

  In addition, the fragrance contained in the capsule CP21 is not particularly limited. , Musk tonkin, myrrh, oak moss or moss de chine, milk incense, peony incense, oris, baturi, rosemary oil, sandalwood oil, vetiver oil, violet leaf absolute, etc. Cinnamic aldehyde, cinnamic alcohol, coumarin, ester, indole, ketone, salicylic acid and related compounds, terpenoids, vanillin and other various synthetic fragrances, or a mixture of two or more thereof.

  Incidentally, in FIG. 2B, the thickness of the buffer member CS21 is exaggerated to make it easy to see the configuration of each layer (inner layer, outer layer). The buffer member CS21 is thinner than the paper tube base paper 12, and the buffer member CS21 is bonded by an adhesive such as vinyl acetate applied to the inner peripheral surface of the inner paper tube base paper 11. Become.

  Here, a method of forming the paper tube 1 will be described with reference to FIGS. FIG. 3 is a cross-sectional view (a) of the paper tube 1 of the present invention and a partially enlarged view (b) thereof, and FIG. 4 is an explanatory view (perspective view) showing a method for forming the paper tube 1 of the present invention. ).

  As shown in FIG. 3A, a buffer member CS21 is bonded to the inner peripheral surface of the paper tube layer LY21 with an adhesive, and the capsule CP21 is sandwiched between the buffer member CS21 and the inner peripheral surface of the paper tube layer LY21. Is done.

  Then, as shown in FIG. 4, a long hollow cylinder is formed by spirally winding the inner paper tube base paper 11 or the like, and the long hollow cylinder thus configured is appropriately set to a predetermined length. The paper tube 1 is formed by cutting.

  In the roll-shaped sheet 100 using the paper tube 1 formed in this way, the fragrance is included in the capsule CP21, and the volatilization of the fragrance can be prevented until the capsule CP21 is crushed, and volatilization of the fragrance can be started by the intention of the consumer. .

Here, Table 1 shows the following conditions, in which Examples 1 to 4 and Comparative Examples 1 to 3 are sealed in a polyethylene film, and assuming product deterioration within the storage period, room temperature is 50 degrees and humidity is 50. It is the test result which shows the relationship of the intensity | strength of the fragrance after standing for 0 hours, standing for 12 hours, standing for 24 hours, standing for 36 hours, and standing for 48 hours.
In Examples 1 to 4, the capsules were crushed after standing for the predetermined time, and the fragrance strength was evaluated.

In Comparative Example 1, 120 μL of fragrance is applied to the gap between the toilet paper and the core using a micropipette at the center of the roll. (Using unscented erière shower toilet)
In Comparative Example 2, 240 μL of fragrance is applied to the gap between the toilet paper and the core using a micropipette at the center of the roll. (Using unscented erière shower toilet)
In Comparative Example 3, 360 μL of fragrance is applied to the gap between the toilet paper and the core using a micropipette at the center of the roll. (Using unscented erière shower toilet)
In Examples 1 to 4, a nonwoven fabric provided with capsules at regular intervals is attached to the same roll as Comparative Example 1 and the like along the spiral of the paper tube base paper inside the paper tube 1. (Nonwoven fabric width 35mm, thickness 160μm derived from pulp raw materials)
A vinyl acetate resin emulsion adhesive is applied to the entire surface of the nonwoven fabric, and capsules are evenly distributed in the longitudinal direction. After capsule application, the nonwoven fabric is applied to the inside of the paper tube in a spiral direction.
Also. In each of Examples 1 to 4 and Comparative Examples 1 to 3, one roll is encapsulated in a PE film having a thickness of 25 μm, and the opening is heat-sealed and hermetically sealed (standing at each time condition).
About Examples 1-4, after opening from a film and destroying all the capsules, aromaticity is confirmed.

(The roll hardness of roll toilet paper 100 is 1.2 kgf)

  In Table 1, 12 verifiers were evaluated in 5 stages, and the average value of 12 verifiers was described (Evaluation criteria: 5: A scent was felt firmly from the roll. 4: A scent was felt 3: Slightly scented 2: Slightly scented 1: No scented)

  As is clear from Table 1, in Comparative Example 1, the average value was 2.7 after standing for 12 hours under conditions of room temperature of 50 degrees and humidity of 50%, whereas Example 1 Then, the average value was 4.3 even after 24 hours of standing at room temperature of 50 degrees and 50% of humidity, and the average value was 4.0 even after standing for 48 hours. Thus, volatilization of the fragrance can be prevented until the start of use, and volatilization of the fragrance can be started at the consumer's will.

  Also, by holding the capsule containing the fragrance between the paper tube layer and the cushioning member, the volatilization of the fragrance due to the capsule being crushed by an unexpected external force is prevented, and volatilization of the fragrance is started by the consumer's will it can.

  Further, as apparent from Table 1, the amount of the fragrance contained in one capsule as in Example 4 is 40 μL to 70 μL, although the amount of the fragrance of Comparative Example 1 in Table 1 is less than 120 μL. Even after 48 hours of standing, the average value in the case of one capsule is 3.1 (the average value of Comparative Example 1 in Table 1 is 1.7), preventing volatilization of the fragrance until the start of use, It can be seen that perfume volatilization can be initiated by the consumer's will.

  Table 2 shows the test results showing the relationship between the size of the capsule sandwiched between the buffer member and the inner peripheral surface of the paper tube layer and the time for recognizing the capsule under the conditions shown below. is there.

  In the evaluation 1 of Table 2, the evaluation “◯” is “3 out of 3 verifiers felt easy to find the capsule.”, And the evaluation “×” was “1 out of 3 verifiers” I felt it was difficult to find the capsule. ”

  In the evaluation 2 of Table 2, the evaluation “◯” is “3 out of 3 verifiers felt that it was easy to pull out toilet paper from the paper holder”, and the evaluation “×” was “of 3 verifiers. One of them felt it was difficult to pull out toilet paper. "

  As is clear from Evaluation 1 in Table 2, when the capsule diameter is 3 mm or less, it takes time to recognize the position of the capsule, and it takes some time to start volatilization of the fragrance by the consumer's intention. Become. On the other hand, if the diameter of the capsule is 4 mm or more, the position where the capsule is present can be easily recognized, so that the perfume volatilization can be easily started by the consumer's intention.

  Further, as apparent from Evaluation 2 in Table 2, when the diameter of the capsule is 7 mm or more, it becomes difficult to pull out the toilet paper from the paper holder. For this reason, the diameter of the capsule is preferably 6 mm or less. For example, when the diameter of the capsule is 7 mm or more, the portion of the capsule swells, interferes with the support portion of the paper holder and does not rotate well, and the toilet paper becomes difficult to pull out.

  As described above, in the embodiment of the present invention, in the paper tube 1 serving as the core of the roll-shaped sheet 100, the hollow cylindrical paper tube layer LY21 formed of the paper tube base paper and the inner peripheral surface of the paper tube layer LY21 are provided. By providing the buffer member CS21 provided and the capsule CP21 in which the fragrance is encapsulated and sandwiched between the buffer member CS21 and the inner peripheral surface, volatilization of the fragrance is prevented until the capsule CP21 is crushed. Perfume volatilization can begin.

  In the embodiment of the present invention, a spiral paper tube having a two-layer structure in which the inner paper tube base paper 11 and the outer paper tube base paper 12 are both spirally wound and bonded with an adhesive is illustrated. However, of course, it may be a flat-wrapped paper tube having a two-layered structure in which the rectangular inner paper tube base paper 11 and the outer paper tube base paper 12 are wound only one layer in a direction perpendicular to the axis.

  Further, in the embodiment of the present invention, a spiral paper tube having a two-layer structure in which the inner paper tube base paper 11 and the outer paper tube base paper 12 are both spirally wound and bonded with an adhesive is illustrated. However, of course, a single-layer paper tube composed of a single paper tube base paper may be used.

  In the embodiment of the present invention, the buffer member CS21 is provided on the inner peripheral surface of the paper tube layer LY21, and the capsule CP21 is sandwiched between the buffer member CS21 and the inner peripheral surface of the paper tube layer LY21. Of course, the buffer member CS21 is provided on the outer peripheral surface of the paper tube layer LY21, and the capsule CP21 can be sandwiched between the buffer member CS21 and the outer peripheral surface of the paper tube layer LY21.

Further, in order to make it easy for the consumer to crush the capsule CP21, the inner surface of the paper tube layer LY21 is sandwiched and the capsule CP21 is sandwiched, and the portion pressed to crush the capsule CP21 at the start of use is colored. Alternatively, marking may be performed.
That is, the user can easily crush the capsule CP21 by pressing the colored or marking portion on the inner peripheral surface of the paper tube layer LY21, and volatilization of the fragrance can be performed by the consumer. You can start.
When the capsule CP21 is applied to the inside of the paper tube 1, when the capsule CP21 is applied to the outside of the paper tube 1, the portion opposite to the capsule attachment portion of the buffer member CS21, for example, A circular marking “●” having a diameter of about 5 mm is given to remind the capsule CP21.
Incidentally, the size and shape of coloring or marking are not particularly limited, and may be any size and shape that can be recognized by the user.
