Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a toilet paper core that can also have a deodorizing function.

Conventional technology Traditionally, camphor was the most common toilet deodorizer, but as flushing became more common, the strong odor of camphor was replaced by lighter-tasting toilet deodorizers such as diasmine. Odorants have come to be liked and used.

In addition, recently, oxide-based fine powder deodorizers,
For example, a fine powder deodorizing agent has been developed whose main ingredients are titanium dioxide and zinc oxide.This deodorizing agent uses a catalytic action to deodorize malodorous components by reducing them to low molecular weight molecules, and the zinc oxide in the component chemically adsorbs oxidizing gases. Furthermore, titanium dioxide is thought to physically adsorb alkaline gases, and is particularly good at adsorbing ammonia and hydrogen sulfide.

Such powdery deodorizers include the product name TZ deodorizer sold by Titan Kogyo Co., Ltd., and as detailed in Japanese Patent Application Laid-Open No. 63-54935,
It is obtained by mixing an aqueous solution of a water-soluble titanium compound and a water-soluble zinc compound with an alkaline aqueous solution and drying the resulting precipitate.

This TZ deodorizer has an excellent deodorizing effect and is in the form of a fine powder, so it can be used by incorporating it into paper, thread, or foam materials such as sponges. In order to incorporate a deodorizing agent into a carrier such as thread paper or foam material, the above-mentioned powdered deodorizing agent is mixed into the raw material of the carrier in advance.
A method has been adopted in which a deodorizing agent is incorporated into the carrier at the same time as the carrier is manufactured.

The carrier containing the fine powder deodorizing agent produced in this manner is used in various ways, but attention is being focused on its use as a toilet deodorizing agent.

Problems that the invention aims to solve However, toilet deodorizers such as those mentioned above are so-called masking, meaning they cover up bad odors with other odors, so they are avoided by people who don't like strong odors. It was hot. Also, they wear out quickly and I often forget to replace them with new ones.

In addition, when incorporating a fine powder deodorizing agent into a carrier, if this deodorizing agent is mixed into the carrier raw material,
Since the carrier is coated with the polymer constituting the raw material of the carrier, the opportunity for the contained deodorizer to come into direct contact with odor components is reduced, and there is also the problem that the deodorizing effect is not good.

Means for Solving the Problems Therefore, the toilet paper core of the present invention is made by polymerizing a flat sheet material and a corrugated sheet material, at least one of which is breathable, and winding both together into a roll. The crest of the corrugated sheet material is combined with the flat sheet material to form a multi-layered cylinder, while the protruding space surrounded by the flat sheet material and the corrugated sheet material contains an oxide-based fine powder deodorizing agent. At the same time, the present invention is characterized in that a carrier whose polymer coating covering the fine powder deodorizing agent is destroyed by being exposed to an atmosphere containing active species is fixed.

Effect In the present invention, the carrier fixed in the protruding space surrounded by the flat sheet material and the corrugated sheet material is exposed to an atmosphere in which active species exist, and the surface is destroyed.
The polymer film that covers the fine powder deodorizer will be destroyed to the extent that the powder particles of the deodorant are exposed to the outside air, and therefore there will be more opportunities for direct contact with odor components. .

Moreover, as a result of this carrier being fixed in a protruding space surrounded by a flat sheet material and a corrugated sheet material, ventilation passages are alternately secured, and this is not possible in a mere flat plate shape. This is because the roll of toilet paper is attached to a holder inside the toilet and is forced to rotate each time the paper is used, which also causes problems with ventilation. good. Furthermore, when the paper is used up, the paper is replenished and replaced with a new one with a fixed carrier, so there is no need to forget to change the carrier, and the carrier can be replaced in accordance with the frequency of use of the toilet.

Example Next, an example of the present invention will be described. In this example, a flat sheet material is polymerized on both sides of a corrugated sheet material. In manufacturing this, one set of A carrier is fixed between the flat sheet material and the corrugated sheet material, which is then finished as a carrier fixing sheet, and while the front flat sheet material is polymerized onto this carrier fixing sheet, both are integrally rolled into a roll shape. The explanation will be made assuming that the corrugated sheet material is wound to form a multiple cylinder in which the upper and lower corrugated crests of the corrugated sheet material are joined to the inner and outer flat sheet materials.

FIG. 1 is a perspective view showing a state in which the carrier fixing sheet and the front flat sheet material are being wound together, and 1 is the carrier fixing sheet and 2 is the front flat sheet material.

As shown in FIG. 2, the carrier fixing sheet 1 contains a fine powder deodorizing agent in the protruding space 5 formed by the inner flat sheet material 3 and the corrugated sheet material 4 when both sheets are polymerized. A carrier 6 is fixed.

The flat sheet materials 2 and 3 and the corrugated sheet material 4 are
A paper material equivalent to a conventional toilet paper core may be used, but a soft sheet material such as nonwoven fabric, woven fabric, or knitted fabric may also be used for either one. In this example,
A conventional paper material is used for the flat sheet material 2 for the front surface, and a large number of small holes 7 are perforated throughout the surface of the flat sheet material 3 and the corrugated sheet material 4 for the inner surface of the paper material coated with a so-called hot melt agent. using things. Further, the carrier 6 contains an oxide-based fine powder deodorizing agent, and in this embodiment, a cotton-like tangle of nylon threads containing the TZ deodorizing agent is used. The TZ deodorizer is mixed in advance with nylon-based raw materials, and by cutting nylon threads manufactured from this raw material into predetermined lengths and entangling them, a cotton-like carrier containing the TZ deodorant is created. is being made. In that case, the TZ deodorizer may be kneaded into pellets, used as master pellets, and mixed with virgin pellets made of only nylon and this master pellet during spinning. Direct mixing may be used during melt spinning, but each fine powder must be uniformly dispersed. If the dispersibility is poor, a group that binds to an organic material and a group that binds to an inorganic material in the same molecule must be mixed. They may be mixed by treatment with a so-called coupling agent, surfactant, etc., which chemically binds the two groups or improves affinity through a chemical reaction.

Other materials that can be used as the carrier include synthetic fibers such as acrylic and polyester polypropylene, recycled fibers such as rayon, and semi-synthetic fibers such as acetate.

Further, the carrier is exposed to an atmosphere in which active species exist before or after being fixed between the flat sheet material and the corrugated sheet material, thereby destroying the film layer property on the surface of the carrier.

In this example, the nylon thread is made into a cotton-like shape, and before it is fixed between a flat sheet material and a corrugated sheet material, it is exposed to an atmosphere in the presence of ozone, thereby finely etching the surface of the fiber. This destroys the film covering the fine powder deodorizer.

In order to expose the carrier to an atmosphere in which ozone exists, for example, the ozone extraction tube from an ozone generator may be applied to the surface of the carrier to gradually transfer the ozone, or the carrier may be left in a container connected to the ozone extraction tube for a predetermined period of time. ,
In this case, the surface of the carrier becomes rough due to the oxidizing action of ozone, and the film on the fine powder deodorizer is broken. At this time, the deodorizing agent is also subjected to the oxidizing effect of ozone, but since this deodorizing agent is originally an oxide, there is no deterioration in performance due to ozone.

In addition to ozone, the active species mentioned above include ions,
There are radicals, electrons, atoms, laser light, radiation, especially ionizing radiation, etc. Exposure to an atmosphere in which these active species exist means that the active species is irradiated onto the carrier as a beam or shower,
Alternatively, it means that the carrier is placed in an atmosphere filled with the active species, and the energy of these active species acts physically and chemically, thereby causing the polymer of the coating that covers the fine powder deodorizer to The film is melted, evaporated, oxidized, and eroded, resulting in fine etching of the film, thereby destroying its properties. In order to create such an atmosphere in which active species exist, it is desirable to be able to select the active species, control their energy, and furthermore be able to scan the source of the active species over the carrier.

As such means, techniques such as ion etching, corona discharge, plasma discharge, electron beam processing, laser processing, etc. can be used.

In addition, when fixing the carrier in the protruding space formed by the flat sheet material and the corrugated sheet material, the second
As shown in the figure, a heat roller is formed by stacking a flat sheet material 3, a layered carrier 6', and a flat corrugated sheet material 4' like a sanderch, and forming corrugated irregularities. 9, the corrugated sheet material 4' is press-formed into a sinusoidal cross-section, and the hot melt agent at the crest of the corrugation is melted and bonded to the flat sheet material 3. In this case, the carrier is partially crushed and buried in the hot melt agent,
Also, depending on the conditions, it may melt itself and become integrated with the hot melt agent, forming a protruding space 5 with ventilation passages 8 on both sides.

When bonding a corrugated sheet material to a flat sheet material as in the above embodiment, it is convenient to use means such as thermal welding, high frequency welding, and ultrasonic welding. Sewing, even bonding with adhesives can be used.

In the present invention, the carrier fixing sheet 1 on which the carrier is fixed is first made into a diamond-shaped strip, and the flat sheet material 2 for the front is prepared as a similar diamond-shaped strip. As shown in Figure 1, while applying adhesive to the crest of the corrugated sheet material 4 on the side of the carrier fixing sheet 1, the carrier fixing sheet 1 is placed in a state where the two are shifted.
The flat sheet material 2 for the front is superimposed on the corrugated sheet material 4, and both are integrally wound to form a cylinder.

Therefore, if paper is wrapped around the cylindrical body obtained in this way and used as a core of toilet paper, it can be attached to a conventional holder as is, and the deodorizing agent contained in the carrier will exert its original deodorizing power. Moreover, since the paper is forcibly rotated each time it is used, odor components can be stirred and further contacted.

Furthermore, when the paper is used up, the core can be replaced as well as the paper replenishment, so it is obvious that you have forgotten to replace it like in the past.Furthermore, this is done in accordance with the frequency of use of the toilet. It is also ideal in proportion to the amount of odor generated.

In addition, after this wick is manufactured, until it is wrapped in paper and used in the toilet, it is possible that other odors may be absorbed and the deodorizing power decreases, so do not place the wick on the side. It is desirable to seal it with adhesive film or the like.

Furthermore, since the present invention is not a conventional masking method, it is suitable for people who are sensitive to strong odors, and is especially suitable for deodorizing flush toilets.

The above description has been made using a carrier containing a TZ deodorizer whose main components are titanium dioxide and zinc oxide, but it is not limited to this TZ deodorizer. Of course, it can be applied in the same way even when it contains oxides such as oxides such as oxides, other metal oxides, and other oxide-based deodorizers. This may be twisted into a thread and further structured by weaving or knitting, or may be a foam structure instead of a fibrous structure.

Further, in the above embodiment, the flat sheet material is used on both the front and back sides, but the invention is not limited to this, and it may be used on either the front or the back.

Effects of the invention Therefore, according to the invention, the carrier fixed in the projecting space has more opportunities to come into direct contact with odor components, and each time the paper is used, it is forced to Since it can be rotated, odor components can be agitated and odor contact can be carried out efficiently. Furthermore, when the paper is used up, the paper is replenished and replaced with a new fixed carrier, so there is no need to forget to change the paper, and it is possible to replace the paper in proportion to the frequency of use of the toilet and the amount of odor generated.

Of course, since it is not a conventional masking method, it is suitable for people who do not like strong odors, and it is especially suitable for deodorizing when washing with water.Since it is disposable, it is a product that exactly matches the sensibilities of modern people. can be provided.
