Abstract
Description
【Technical Field】 【0001】 The present invention relates to roll paper products, particularly packages for toilet rolls. 【Background Art】 【0002】 In the case of toilet rolls, it is common to package them in plastic wrapping films in units of, for example, 4 or 12. A finger-hanging hole is formed at the upper part of the wrapping film, and it is a package considering the carrying by consumers from the store. For the package taken home, the wrapping film is broken to extract the entire amount of the toilet roll, and the wrapping film is either discarded or the required number is taken out, and the remaining number is left in the wrapping film in a semi-packaged state, for example, stored in the toilet. 【0003】 On the other hand, in the case of one toilet roll, there is a product covered with wrapping paper. In use, the wrapping paper is discarded and the toilet roll is hung on a holder. 【0004】 Packages of multiple toilet rolls wrapped in plastic wrapping films may not be preferred according to the recent trend of decarbonization. 【Prior Art Documents】 【Patent Documents】 【0005】 【Patent Document 1】 Japanese Patent Application Laid-Open No. 2014-169127 【Summary of the Invention】 【Problems to be Solved by the Invention】 【0006】 Therefore, the main problem of the present invention is to provide a package for roll paper products, particularly toilet rolls, that is suitable for the trend of decarbonization and provides a deodorizing function during storage. 【Means for Solving the Problems】 【0007】 The following are representative examples of how the above problems were solved. 【0008】 <Typical form of packaging for roll paper products> A package in which multiple roll paper products are wrapped in packaging material, The aforementioned packaging material is wrapping paper, The inner surface of the aforementioned packaging paper is coated with a deodorizing component that reduces or eliminates odors. The aforementioned roll paper products are stacked in the height direction. Stacking section in the height direction of roll paper products Covering over A paper band is wrapped around it, and this band does not extend above or below the aforementioned stacking section. A packaging material for roll paper products characterized by the following features. [Effects of the Invention] 【0009】 According to the present invention, the product is in line with the trend toward decarbonization and exhibits a deodorizing function when roll paper products are stored. [Brief explanation of the drawing] 【0010】 [Figure 1] This is a partially broken front view of a toilet roll package installed vertically. [Figure 2] This is a partially cut front view of a toilet roll package in its installed state, with the top wrapping paper removed and the top toilet roll taken out.

[Figure 4] This is a perspective view showing an example of packaging with four toilet rolls stacked on top of each other. [Figure 5] This is a cross-sectional view showing an example of the layered structure of wrapping paper. [Figure 6] This is a perspective view of a usage scenario where, in a package containing four stacked toilet rolls, two toilet rolls are removed, and the remaining toilet rolls are stored in a semi-packaged state, still in their original wrapping paper. [Figure 7] It is an explanatory perspective view for a waste bag after using a toilet roll. [Figure 8] It is a partially broken front view showing a packaging style with four toilet rolls placed horizontally. 【Embodiments for Carrying out the Invention】 【0011】 Hereinafter, embodiments of the present invention will be described in detail while referring to the accompanying drawings. 【0012】 FIG. 1 shows a state where a package of toilet rolls 10 is installed. In the illustrated example, the paper tubes are vertical, there are four in one row, and they are stacked in three rows, totaling twelve toilet roll packages. 【0013】 In the present invention, wrapping paper is used as the packaging material. The most suitable wrapping paper is kraft wrapping paper. Kraft paper is paper made from kraft pulp, and it is particularly desirable that it be brown paper made from unbleached kraft pulp. As the basis weight of the kraft wrapping paper, as will be described later, in addition to the strength as wrapping paper, from the viewpoint of having self-standing rigidity in an open state at the upper part, 50~200 g / m 2 is desirable. The paper thickness is preferably 100~300 μm. If the basis weight is excessively low, there is a possibility of breakage during packaging or transportation. Increasing the basis weight excessively is not economical. 【0014】 As a packaging form, as shown in FIG. 3, it can be made into a caramel packaging. That is, a cylindrical body having an overlapping portion R on the side is formed, and folding and overlapping are performed at the top (upper part) and the bottom (lower part) thereof to form a closed end portion. 【0015】 As shown in Figure 5, a deodorizing component that mitigates or eliminates odors is applied to the inner surface of the base paper 10c of the packaging paper 10, for example, by coating. In this case, the deodorizing component of the deodorizing component layer 10a is preferably a deodorizing component that mitigates or eliminates at least ammonia odor, from the perspective of installing the packaging in a toilet. In addition, it is desirable that it also eliminates odors originating from feces. In addition to deodorizing components, it is also possible to add fragrance components. 【0016】 Such packaging may be placed on store shelves. If the packaging is exposed to rain while on display, moisture can penetrate through the wrapping paper to the toilet roll, potentially rendering the highly absorbent toilet roll unsaleable. Therefore, as shown in Figure 5, it is desirable to apply a water-repellent or waterproof layer 10b to the outer surface of the base paper 10c by coating or other means. 【0017】 Consumers should not tear open the packaging they have purchased and brought home, remove the entire contents of the toilet roll, and then discard the packaging, but rather make effective use of the packaging. One way to utilize this product is to take out the required number of items, leave the remaining items in their packaging, and store them, for example, in the toilet. 【0018】 In this case, the wrapping paper exhibits sufficient rigidity compared to the wrapping film, and can therefore maintain an upright position, as shown in Figure 2, for example. To further enhance this self-supporting capability, it is desirable to wrap a band material 30, particularly preferably made of paper, around the overlapping portion R, as shown in Figures 2 and 3. The position of this band material 30 is preferably at least below the center in the height direction, as shown in Figure 7, which is a typical example. 【0019】 The overlapping sections R, top (upper part), and bottom (lower part) of the wrapping paper, and the opposing surfaces of the folded overlapping sections (folded flaps 10A, 10B), can be joined together, continuously or intermittently, using, for example, a hot-melt adhesive. 【0020】 On the other hand, in accordance with the aforementioned usage configuration, for example as shown in Figure 2 or Figure 6, it is desirable to form a tearing perforation 20 that wraps around the entire body of the packaging in order to take out the required number of items and leave the remaining items in the packaging paper 10 in a semi-packaged state for storage, for example in a toilet. The position of the tearing perforation 20 should preferably be at the top of the packaging, i.e., at a position where the topmost toilet roll 11 does not tip over, for example, 10 to 80 mm from the top edge. 【0021】 Figure 2 shows the state after tearing along the perforation line 20, removing the top section, and taking out two toilet rolls, leaving 10 toilet rolls in the partially wrapped packaging paper 10. As a result of removing the top section, an opening is formed at the top. 【0022】 In this state, because the top edge of the packaging is open, the inner surface of the packaging paper and the outside air inside the toilet come into free contact, and as a result, the odor BS of the toilet comes into contact with the deodorizing component layer 10a on the inner surface of the packaging paper 10, thus achieving deodorization. 【0023】 A handle 40 may be provided on the packaging, for example, as a strip on the top, if necessary. While it is preferable that the handle 40 be made of paper, a plastic band may also be used if the band itself is to be peeled off the packaging and disposed of separately. The handle 40 can be attached to the outside of the packaging 10 using hot-melt adhesive or the like. 【0024】 The example above shows 12 packages, but the number is not limited as long as it involves multiple toilet rolls. For example, as shown in Figure 4, it also includes configurations such as stacking two vertically oriented toilet rolls side by side in two layers to store a total of four toilet rolls. 【0025】 Figure 6 shows the state after tearing along the perforation line 20, removing the top part, and taking out the two toilet rolls, leaving the two toilet rolls in the partially wrapped packaging paper 10. 【0026】 In the above example, the toilet roll 11 is packaged in a vertical orientation with its paper core oriented vertically. However, as shown in Figure 8, the toilet roll 11 can be packaged in a horizontal orientation with its paper core oriented horizontally. 【0027】 The packaging 10 provides deodorizing function until all toilet rolls 11 are removed, after which, as shown in Figure 7, it can be used as a waste storage bag for toilet waste (e.g., used toilet cleaning sheets) W. In this case, the band material 30 can be peeled off the packaging paper 10 and used as a sealing band to bundle and seal the opening of the packaging bag. 【0028】 Suitable materials can be used as the deodorizing component according to the present invention. In addition to materials that exhibit physical deodorizing effects through adsorption, etc., in the form of granular solids such as zeolite, chemical deodorizing components that chemically deodorize malodorous components can be suitably adopted. 【0029】 Here, the chemical deodorizing component can be a compound having a ketone group or aldehyde group that has a deodorizing effect through a neutralization reaction against odors containing amine groups, such as ammonia derived from urine components. In addition to ammonia, compounds that also exhibit deodorizing effects against odor components such as hydrogen sulfide, trimethylamine, methyl mercaptan, and isovaleric acid are particularly preferred. 【0030】 Furthermore, it is desirable that the chemical deodorizing component contains one of the following: polyphenols, polyphenol derivatives, and polyphenol analogs (hereinafter also referred to as polyphenols, etc.). Polyphenols, etc. are extracted from plants and processed plant products, and have a deodorizing function against ammonia, which is at least one of the main malodorous components present in toilet spaces, due to the reactivity of phenolic hydroxyl groups. Of course, there are also polyphenols that have a deodorizing function by reacting with hydrogen sulfide, methyl mercaptan, and trimethylamine, which are known to be malodorous components in toilet spaces in addition to ammonia, and the above-mentioned polyphenols, etc. may be such. For example, among polyphenol derivatives, those that have been artificially given appropriate functional groups to polyphenols with high molecular weight, as in Patent No. 3919729, to add or enhance the deodorizing function against specific components can also be used. 【0031】 It is desirable to use polyphenols or the like as the deodorizing component, and to use volatile deodorizing fragrances as the volatile deodorizing substances described later, with ester compounds as the fragrance components, because this provides a deodorizing effect through different deodorizing mechanisms: the deodorizing effect due to the reactivity of phenolic hydroxyl groups and the deodorizing effect due to the exchange reaction of the ester compounds. Furthermore, polyphenols and the like do not affect the aroma or deodorizing effect of the ester compounds. In particular, the combination with citronellyl formate and phenylethyl formate is desirable in terms of aroma and effect. 【0032】 Although the aforementioned polyphenols are not easily impregnated into paper, they can be impregnated when applied to paper together with lower alcohols such as ethanol, methanol, butanol, and propanol. 【0033】 More preferred examples of polyphenols include tannins, catechins, rutins, anthocyanins, ellagic acid, coumarins, flavones, and their derivatives or precursors. These exhibit particularly high deodorizing effects against odor components in toilets and do not affect the fragrance of the volatile deodorizing fragrances, which are ester compounds. 【0034】 Among the specific examples above, tannins and their derivatives are particularly preferred. Tannins and tannin derivatives have a large molecular weight and contain many phenolic hydroxyl groups, resulting in excellent deodorizing properties. The tannin can be either condensed tannin or hydrolyzed tannin. Among tannins, persimmon tannin derived from persimmons has a very large molecular weight and is extremely effective in deodorizing, so it is preferable to include at least one of persimmon tannin or a persimmon tannin derivative as a deodorizing component. If persimmon tannin is included, it is also preferable to include tea catechins. The above-mentioned polyphenols may also be derived from commercially available polyphenol-based deodorizing components. Examples of commercially available polyphenol-based deodorizing components include Pancil COS-15, Pancil COS-17, Pancil CL-10, Pancil AS-10, Pancil AS-20, Pancil BA-210-1, Pancil COS-5, Pancil FG-22, Pancil FG-25, Pancil FG-30, Pancil FG-60, Pancil FG-70, Pancil FG-99, Pancil FX10, Pancil PO-10, and Pancil BA-200E-1, all manufactured by Release Kagaku Kogyo Co., Ltd. 【0035】 In addition to the aforementioned chemical deodorizing components, volatile deodorizing fragrances can also be used. There are no particular limitations on the amount of volatile deodorizing fragrance that can be used. The specific amount of volatile deodorizing fragrance can be determined by considering the specific type used, the deodorizing effect, the scent, the fragrance profile, and the intensity of the fragrance. 【0036】 The aforementioned volatile deodorizing fragrance is a fragrance that is volatile at room temperature and emits an aroma through volatilization, while also undergoing a chemical reaction with malodorous components in the toilet space. In particular, it transforms malodorous components into substances that are odorless or have little odor through this chemical reaction. Malodorous components are those that are problematic in the toilet space, and typically include ammonia and trimethylamine, which cause urine odor, and methyl mercaptan and hydrogen sulfide, which cause fecal odor. 【0037】 Volatile deodorizing fragrances release their aroma through volatilization, making them highly effective against malodorous components such as ammonia diffused within the toilet space. In other words, the deodorizing fragrance is released into the toilet space, quickly coming into contact with malodorous components such as ammonia that are diffused within the space, thus exerting its deodorizing effect. Furthermore, as the fragrance diffuses within the toilet space, it also comes into contact with urine splashed on the walls and floor, suppressing the urine odor caused by ammonia and other substances emitted from the urine. In short, it is highly effective in deodorizing the source of the odor. Moreover, because volatile deodorizing fragrances are fragrances, the strength of the deodorizing effect can be easily perceived by the intensity of the fragrance, and changes such as a decrease in fragrance intensity or a change in fragrance intensity can be recognized as a decrease in deodorizing effect. 【0038】 The volatile deodorizing fragrance preferably contains one or more ester compounds. Many ester compounds exhibit floral or fruity scents, making them suitable as fragrances for use in toilet spaces. At the same time, they can remove or reduce ammonia odor by reacting with ammonia, the main malodorous component in toilet spaces. 【0039】 The above chemical deodorizing components can be used in combination with volatile deodorizing fragrances containing ester compounds. 【0040】 Preferred ester compounds include linalyl acetate, eugenyl acetate, geranyl acetate, savinyl acetate, sabinene hydrate, citronellyl acetate, terpinyl acetate, neryl acetate, butyl algerate, vetiveryl acetate, benzyl acetate, benzyl benzoate, bornyl acetate, bornyl isovalerate, methyl anthranylate, methyl salicylate, methyl butyrate, methyl benzoate, menthyl acetate, lavandulyl acetate, linalyl acetate, or formic acid esters. These exhibit a high deodorizing effect against ammonia while possessing an aroma that is pleasant to humans. The volatile deodorizing fragrance preferably contains one or more selected from this group. 【0041】 On the other hand, it is preferable that the ester compound has 5 or more carbon atoms. More preferably, specifically, it is preferable that it has 6 to 12 carbon atoms. If the number of carbon atoms is less than 5, the volatility may be too high, and the persistence of the fragrance and deodorizing effect may not be sufficient. In particular, fragrances related to ester compounds with 6 to 12 carbon atoms often have a vapor pressure of 0.02 mmHg or more and less than 0.1 mmHg at 20°C in terms of volatility. This range is called the so-called middle note in fragrances, and it has an excellent balance between persistence and volatility. Considering the period during which a toilet roll is generally used up, it is possible to fully develop the fragrance and deodorizing effect throughout the life of the toilet roll. Compounds with more than 12 carbon atoms are also acceptable, but when the number of carbon atoms exceeds 12, it becomes what is called the base note in fragrances, and its rapid volatility is somewhat inferior. 【0042】 Particularly preferred volatile deodorizing fragrances are those containing at least one of citronellyl formate and phenylethyl formate. These easily adjust the fragrance to a floral scent such as rose, exhibiting a desirable fragrance in toilet spaces, and are highly effective at chemically deodorizing nitrogen sources, especially ammonia. Furthermore, they are compatible with urine odor in terms of masking properties. In addition, citronellyl formate and phenylethyl formate, with 6 to 12 carbon atoms, have a middle note fragrance profile, resulting in excellent usage and deodorizing duration, and their fragrance is easily perceived, making their deodorizing effect easily recognizable. When using citronellyl formate and phenylethyl formate, the content should be between 1% and 10% by mass of the total amount of fragrance used per toilet roll. Within this range, a sufficient fragrance can be perceived while also achieving a deodorizing effect. 【0043】 On the other hand, the deodorizing component according to the present invention may also contain organic acids and organic acid salts. Organic acids and organic acid salts also have a deodorizing effect. It is desirable that the organic acids and organic acid salts are highly safe for the human body, and examples include lactic acid, tartaric acid, malic acid, fumaric acid, succinic acid, citric acid, glutaric acid, amino acids, adipic acid, ascorbic acid, or inorganic or organic salts thereof. Examples of inorganic bases that form salts include hydroxides, oxides, carbonates, and bicarbonates of alkali metals or alkaline earth metals such as sodium, potassium, lithium, calcium, and magnesium. Examples of organic bases include nitrogen-containing bases, such as primary, secondary, or tertiary amines, and compounds having groups such as imino groups, guanidino groups, imidazolino groups, imidazolyl groups, and pyridyl groups. It will be done. 【0044】 Regarding the amount of deodorizing component to be applied, from the perspective of deodorizing effect, it should be 0.002 to 6.0 g / m². 2 It is desirable that this be the case. More preferably, 0.2 to 2 g / m 2 That is the case. 【0045】 On the other hand, the material for forming the waterproof layer 10 having water-repellent or waterproof function in the embodiment is not limited. 【0046】 For example, silicone-based, paraffin-based, alkylchromic chloride-based water repellents, waxes (paraffin wax is particularly preferred), natural fibers, synthetic resins (especially UV-curing resins), and silicones can be used. A water-repellent performance of R8 to R10 is desirable, in accordance with JAPAN TAPPI Paper Pulp Test Method No. 68. 【0047】 • Basis weight is measured as follows: After pre-drying the sample or test piece, leave it in a test room or apparatus under standard conditions (temperature 23±1°C, relative humidity 50±2%) to reach a constant weight. Pre-drying means bringing the sample or test piece to a constant weight in an environment of 100°C. Note that pre-drying is not necessary for fibers with an official moisture content of 0.0%. Using a sample-taking template (100mm × 100mm), cut out a sample measuring 100mm × 100mm from the test piece that has reached a constant weight. Measure the weight of the sample, multiply it by 10 to calculate the weight per square meter, and this is the basis weight. 【0048】 • "Thickness" was measured using an automatic thickness measuring instrument (KES-G5 handy compression measurement program) with a load of 0.098 N / cm². 2 , and pressure area: 2cm 2 Automatic measurement is performed under these conditions. [Examples] 【0049】 To confirm the effects of the present invention, the deodorizing effect against the main malodorous components in a toilet space was tested and confirmed using the following procedures (1) to (4) in Example 1, in which deodorizing component A that reduces or eliminates at least ammonia odor was applied; Example 2, in which deodorizing component B that reduces or eliminates at least ammonia odor was applied; and a comparative example in which no deodorizing component was applied. (1) Place the odors in a 5L airtight container so that the concentrations are ammonia: 100 ppm, hydrogen sulfide: 4 ppm, trimethylamine: 28 ppm, and methyl mercaptan: 8 ppm to 130 ppm. (2)Basic weight 160g / m 2 A piece of kraft paper measuring 41mm x 114mm is impregnated with a deodorizing agent to create a sample. (3) Place the kraft paper prepared in (2) into a sealed container with the gas prepared in (1) and leave it for 60 minutes. (4) After standing for 60 minutes, the gas concentration in the airtight container for each sample was measured, and the gas decomposition effect was confirmed using a gas detection tube. The results are shown in Table 1 below. 【0050】 [Table 1] 【0051】 Looking at Table 1, we can see the following: • Blank kraft paper without a deodorizer (comparative example) absorbs the odor itself, so after 60 minutes the odor is slightly reduced, but the deodorizing effect is low. • Example 1 did not show sufficient deodorizing effect against trimethylamine, but it did show sufficient deodorizing effect against other malodorous components. In Example 2, the deodorizing effect against each malodorous component was high, confirming that the deodorizing effect is observed in the usage environment envisioned by the present invention. Furthermore, Examples 1 and 2 showed a significant difference in deodorizing effect after 60 minutes. Based on these results, it can be said that the packaging paper according to the present invention does not release the deodorizing components and is excellent in immediate effectiveness against malodorous components diffused in the toilet space and in deodorizing effect against the source of the odor. [Industrial applicability] 【0052】 Although the above example described the present invention in relation to toilet paper, it can also be used for roll products such as kitchen paper used for handling odor-emitting foods such as meat and fish. In this latter example, the purpose is to deodorize the kitchen.
