Description

  The present invention relates to a wiping article in which a sheet material having a shape and size that can be used as a towel or towel when compressed is compressed and stored in a pack so that it can be used in a wet state.

  Wet towels, wet napkins or wet towels are called by various names, but there are products used for the common purpose of wiping each part of the body such as hands and face, etc., and these are the same as wiping supplies Conceivable. These are made by impregnating moisture into a non-woven fabric cut into a regular shape and packaged one by one in a plastic film bag, or by continuously forming perforations for each fixed size, Some of them are filled so that they can be pulled out from the mouth of the container. Such a wiping article is ready for use and has a large and bulky packaging form, which is problematic in portability. Moreover, since materials, such as a nonwoven fabric, have been in contact with moisture for a long time, there is a possibility of expiration of use or deterioration.

  JP-A-11-139463, on the other hand, contains a semi-dry tissue and a sachet filled with an aqueous liquid in an outer bag and breaks the bag due to an increase in internal pressure during microwave heating, resulting in a hot and steamed state. An invention that can be made is disclosed. For this reason, in addition to having the problem of the previous period, it cannot be used when heating by microwaves cannot be performed, and it cannot be used at a place without facilities. In addition, utility model registration No. 3072960 folds a dry hand towel body, stores an individual liquid bag filled with water or disinfectant therein, and squeezes the hand towel body from the outside during use to squeeze water in the bag or Disclosed is a device capable of crushing a disinfectant solution and soaking it in a wet body. However, in this case, the dry wet towel body is only reduced to a folded state, and it is difficult to see how much water or liquid has soaked from the individual liquid bag stored in the wet towel body, and the individual liquid bag is removed. There is a problem that it takes time and effort.

  Therefore, the present inventor can separate the small compressed sheet material and the liquid, enclose them in one bag pack, supply the liquid to the sheet material, inflate it, and take it out and use it as it is. Developed an excellent wiping product. This wiping product can be used in a wet condition when necessary, so it can be used conveniently, for example, for elderly care, and also for wiping dirt during outdoor activities. Can be used. Furthermore, even if there is no heating device or ice, it can be used warm or cold, so that a cool feeling can be obtained in summer, while a warm feeling can be obtained in winter. Have. In order to use this, it is only necessary to break the separation band that bisects the inside of the pack, impregnate the liquid material of one part into the sheet material of the other part, and expand the compressed sheet material . However, there is a problem that it is difficult to break well because the separation band is made of a uniform thickness and crosses the pack.

JP-A-11-139463 Utility model registration No. 3072960

  The present invention has been made paying attention to the above points, and the problem is that, in a wiping article having a structure in which the inside of the pack is separated by a breakable separation band, the separation band is accurate and relatively easy. The sheet material of the other part is impregnated with the liquid which has been divided into two parts and is divided into two parts, and is expanded. Another object of the present invention is to provide a wiping article that can be used in a wet state without requiring any tools or auxiliary tools.

In order to solve the above-mentioned problem, the present invention is a wiping article in which a sheet material having a shape and size that can be used as a towel or a towel when expanded is compressed and stored in a pack.
The pack for storing the sheet material has a pack structure that is not broken by pressure by forming a strong adhesion portion on the periphery of the pack using a thermoplastic film, and inward from the strong adhesion portion on the periphery of the pack. It has a rupture force guide portion that extends, and breaks with pressure by forming a weak bond portion weaker than the strong bond portion between the rupture force guide portion or the rupture force guide portion side and the pack peripheral side. A possible separation band is provided, and the inside of the pack is separated into at least two chambers, and one chamber provided with the breaking force guiding portion is filled with a liquid to be impregnated and expanded by breaking the separation band, The other room is inflated by impregnation with liquid and has a structure in which a sheet material compressed into a shape and size that can be used as a towel or towel is arranged. A.

  As described above, the wiping article according to the present invention may be considered as a generic term for a wet towel, a wet napkin or a wet towel, etc. It is planned to be used for the common purpose of wiping others. As the sheet material constituting the wiping article according to the present invention, a sheet material that is expanded so as to be infiltrated with liquid and compressed to have a shape and size that can be used as a hand wipe when expanded is used. The sheet material is in a small compressed state before use, expands when impregnated with a liquid during use, and expands to restore the original shape, resulting in a wet wiping article. That is, the shape and size can be used as a hand wipe. The use at the time of restoration may be a towel, a handkerchief, or a towel, but is not limited thereto.

  This small-compressed sheet material uses a woven or non-woven fabric made of synthetic resin or natural resin fibers, cut it into almost constant dimensions, and, for example, a diameter of 1 to several centimeters by compression molding means. Use coins that are 0.5 to several centimeters in height. Of course, it may be a rectangular shape such as a dice, or a granular or plate shape such as gum, and the size is not limited to the above dimensions. Thus, what compressed the sheet material small maintains the state compressed small in the dry state, Therefore Portability is not impaired.

  The above-mentioned sheet material compressed to a small size is handled in a state of being stored in a pack, and when used, the liquid is supplied to the other chamber by applying pressure, for example, by striking one chamber of the pack in which the liquid is sealed. The sheet material is then impregnated to expand in the pack, and then taken out from the pack and used. In the present invention, therefore, the inside of the pack is separated into at least two chambers by a separation band. A small compressed sheet material is placed in one of the two chambers of the pack, and is impregnated and expanded by breaking the separation zone. Place in another room. That is, the separation band is a means for separating the two chambers, and is also a means for breaking when passing through the two chambers when pressure is applied. A typical container corresponding to such a pack is preferably a flat bag.

  The separation band may be provided over the entire width of the middle part of the pack, or may be provided only in a part. That is, the separation band can be provided together with the strong adhesion portion, or can be provided only with the weak adhesion portion. In addition, the separation band is formed as a structural portion that can be broken by applying pressure by striking, for example. Therefore, the pack structure that does not break means a structure that does not break due to, for example, a pressure at which the separation band breaks.

  In order to provide a weakly bonded separation zone, different types of thermoplastics that are bonded with weaker adhesive strength than the thermoplastics used in the pack are interposed between the thermoplastic films that make up the pack. There is a method of adhering (the invention according to claim 2). Further, a method of bonding the same kind of thermoplastic plastics at a temperature lower than that of the strongly bonded portion is also applicable.

  On the other hand, since a problem that it is difficult to break well with a simple band-shaped separation band has been clarified, in the present invention, a breaking force is applied to the separation band so as to pass through two chambers by applying a pressure higher than a predetermined pressure. In order to concentrate, the following improvements were made to solve this. As one of the means, a pack having the bag-like structure described above is provided with a pack structure that does not break by using a thermoplastic film and strongly adhering the periphery, and is directed inward from the strong adhesion portion of the pack periphery. And a breaking force guiding portion extending. The breaking force guiding part may be provided in the strong adhesion part or in the weak adhesion part. Further, it may take a form extending inward from both the left and right sides of the pack periphery, or may take a form extending inward from either the left or right side of the pack periphery.

  It can be said that the breaking force guiding portion is a portion that divides the inside of the pack into two parts, but not completely. The breaking force guiding portion is a means for avoiding dispersion of breaking force and concentrating breaking force by inducing an external force to an easily breakable portion called a separation band. As a result, the liquid filled in one of the two chambers can be reliably supplied to the sheet material arranged in the other, which is compressed to a small size.

  The breaking force guiding portion can take various forms, but basically, the breaking force guiding portion has a configuration extending inward from the strong adhesion portion on the periphery of the pack. is there. Further, it is desirable that the breaking force guiding portion has an inclined portion that extends inward from the strong adhesion portion on the periphery of the pack and is inclined toward the easy breaking portion. ). That is, what can guide the external force applied to the pack to the separation zone corresponds to the inclined portion of the present invention. Therefore, the inclined portion in the present invention does not necessarily need to be a linear inclination. For example, the bent part is also inclined, and the stepped part also corresponds to the inclination in the present invention.

  The breaking force guiding portion extends inward from the strong adhesion portion on the periphery of the pack, but it may have a form extending inward from both the left and right sides of the pack, or inward from either the left or right side. It may be a form that extends toward the surface. 1 and 2 have a substantially symmetric structure in which inclined portions are located on the left and right sides of the easily breakable portion (the invention according to claim 4). However, in the case shown in FIGS. 9, 10, etc., the inclined portion is located only on one side of the easily breakable portion. The width of the easily breakable portion located at the tip of the inclined portion can be arbitrarily determined. When the weak adhesive strength of the easy-to-break portion is constant, the smaller the width, the more concentrated the external force, so the fracture becomes easier, and if the weak adhesive strength is weak, a width of a certain width or more may be required. is there.

  In the wiping article according to the present invention configured as described above, a heating unit that heats the sheet material expanded by liquid impregnation can be provided in the pack, and the sheet material can be used after being warmed. As the heating means, it is most desirable to use a warmer that uses the oxidation action of iron powder, which is called a disposable warmer or a single-use warmer, because of its price, safety, and ease of use. Further, a cooling means for cooling the sheet material expanded by the liquid impregnation can be provided in the pack so that the sheet material can be cooled and used. As a cooling means, it is most desirable to use a cold insulator filled with a chemical substance, called a cooling pack or freezing point, from the viewpoint of price, safety and ease of use. Furthermore, as the liquid used in the present invention, various kinds of water, an aqueous solution containing disinfecting and cooling components, a non-aqueous solution, and any other liquid can be used. When these liquids are colored or colored, the impregnation state is known from the coloring. Moreover, paradoxically, the sheet material can be expanded without using the liquid in the pack.

  Since the present invention is configured and operates as described above, in the wiping article having a structure in which the inside of the pack is divided into two by a breakable separation band, the breaking force guiding portion is formed and the breaking force described above is formed. Since the easy-to-break part composed of the separation band is arranged at the leading end of the guide part, the separation band can be accurately and relatively easily broken, and the liquid in one part can be divided into two parts. The sheet material of the other part can be impregnated and expanded. In addition, according to the present invention, the separation zone can be reliably broken by, for example, striking one chamber in which the liquid of the pack is sealed, so that the tool can be wet without requiring any tools or auxiliary tools. A wiping article that can be used in a state can be provided. Thus, according to the present invention, it is possible to use a wet wiping article when necessary. Further, in the present invention, the sheet material is stored in the pack in spite of being in a small compressed state and is not taken out until it expands due to liquid impregnation. Can be prevented.

  Hereinafter, the wiping article 10 of the present invention will be described in more detail with reference to the illustrated embodiment. FIG. 1 shows an example of a wiping article 10 according to the present invention, which uses a thermoplastic plastic, and strongly adheres four peripheral edges thereof to form a flat bag-like structure pack 11 having a rectangular shape. Formed.

  The code | symbol 12 shows what compression-molded the sheet | seat material small so that it might become a shape and magnitude | size which can be used as hand-wiping etc. if it expands. The sheet material 12 is compression-molded 12 using a woven or non-woven fabric made of synthetic resin or natural resin fibers, and dispersed with ultrafine metal powder having antibacterial properties such as silver and zinc. Then, the original sheet is cut into a fixed size and formed into a size of, for example, a diameter of about 2.5 cm and a height of about 2 cm by compression molding means. The sheet material 12 which is compression-molded small can be formed into a size and shape other than those described above depending on the purpose and application.

  In the illustrated example, as a thermoplastic plastic suitable for the pack 11, in order to provide a pack structure that does not break, a doubled film is used so that the pack 11 does not leak by any chance. I am trying. The illustrated pack 11 is formed by strongly adhering the peripheral edge 13 and extends inward from the strong adhesive portion 14 at the peripheral edge of the pack in the middle portion, and is a break consisting of the strong adhesive portion 14 in the same manner as described above. A force guiding portion 15 is provided. Further, by forming a weakly bonded portion 16 that is weaker than the strong bonded portion 14 between the breaking force guiding portions, a separation band 17 that can be broken by striking is provided, and the interior of the pack is minimally provided in two chambers 18. , 19 are separated.

  In the embodiment represented in FIG. 1, the pack 11 is formed using a polyester film that is a thermoplastic plastic. The pack 11 has a strong extension extending inward from the left and right sides of the periphery. Symmetrical rupture force guide portions 15, 15 made of the adhesive portion 14 are formed. The breaking force guiding portions 15 and 15 are provided with inclined portions 20 and 20 that are inclined toward the center of the pack on the side of the one chamber 18 filled with liquid. The inclined portion 20 constitutes a straight steep inclination, and the width of the separation band 17 set relatively wide is determined between the tip portions.

  In the illustrated example, nylon films are used as the different types of thermoplastic plastics 21 and 21 that are bonded with a weaker adhesive force than the thermoplastic used in the pack 11, and the thermoplastic plastic film constituting the pack 11. The separation band 17 is formed by interposing and adhering with an arbitrary width (see FIG. 3). Adhering the thermoplastic films 21 and 21 means forming the separation band 17, and the adhesive width affects the adhesive force, but can be set to an arbitrary adhesive width, narrow or wide. The adhesion between the different types of thermoplastic plastics (nylon films) 21 and 21 and the thermoplastic plastic (polyester film) used in the pack 11 is a strong adhesion 14.

  Then, a small compressed sheet material 12 is placed in one of the two chambers 19 of the pack 11, and an amount of liquid 22 sufficient to impregnate and expand the above-described material 12 by breaking the separation band 17. And placed in the other chamber 18 of the two chambers of the pack. The liquid 22 may be water, an aqueous solution mainly composed of water, or a liquid composed of a component having a special purpose such as a disinfecting liquid. In that case, it is naturally necessary that the liquid 22 is a stable component in relation to the constituent material of the pack, the constituent material of the separation band, and the like.

  In order to use the wiping article 10 according to the present invention configured as described above, in FIG. 1, the one chamber 18 in which the liquid 22 is sealed is hit with a fist, for example. When this striking force is applied to the pack 11, the pressure accompanying the striking induces the liquid 22, which is an incompressible fluid, to the separation zone 17 along the inclined portion 20 of the breaking force guiding portion 15, and as a result, The separation band 17 cannot withstand the concentrated pressure, and eventually breaks. When the separation band 17 breaks, the liquid 22 flows from the one chamber 18 through the broken portion 23 to the other chamber 19, soaks the sheet material 12 that has been compressed to a small size, and expands it (see FIG. 2). ).

  If the encapsulated liquid 22 is absorbed by completely expanding the small compressed material 12 of the sheet material and does not remain in the pack 11, it can be removed and removed. Therefore, the pack 11 is opened from the cut opening 24, and the wet and swollen one 12 'is taken out and expanded as shown in FIG. 4, and can be used as it is.

  The breaking force guiding portion 15 can take various forms as shown in FIG. Basically, the breaking force guiding portion has a configuration extending inward from the strong adhesion portion on the periphery of the pack. The example of FIG. 5 is the same as that shown in FIG. 1, but is Example 1 having the separation band 17 that becomes the fracture portion 23 having a wide opening width, whereas Example 2 of FIG. 1 is an example having a substantially V-shaped separation band 17 having a narrow opening width, which is composed of a weakly bonded portion 16, all having a breaking force guiding portion 15 and an inclined portion 20 similar to those in FIG. 5. Example 2 in FIG. 6 has a fracture portion 23 'having a narrow opening width. In such a case, since the pressure concentration may be further increased, the thickness of the breaking portion 23 ′ at the tip of the breaking force guiding portions 15, 15 can be increased and the breakability can be suppressed.

  The example shown in FIG. 7 has breaking force guiding portions 25 and 25 having a constant width, inclined portions 26 and 26 are provided inwardly in steep inclinations, and a separation band that can form a wide broken portion 27 at the tip thereof. Example 3 with 17. In contrast to this, in the example of FIG. 8, a rupture portion 27 ′ having a narrow opening width is formed at the tips of the rupture force guide portions 25, 25 having a constant width, which are all formed of the weakly bonded portion 16 as in the example of FIG. 7. This is Example 4 as the separation band 17. In these examples, the pressure increases at a stroke in the central portion of the pack, but the break portion is not necessarily provided in the central portion.

  The example of FIG. 9 has breaking force guiding portions 29 and 29 whose inner side is defined by a loose inclined portion 28, and a middle-width breaking portion 30 is provided between the tip portion and the pack periphery. It is Example 5 which has the separation zone 17 which can be formed. The example of FIG. 10 has a rupture force guiding portion 29, 29 whose inner side is defined by a loose inclined portion 28 on one side, and a medium bond between the strong adhesion portion 31 provided on the other side. It is Example 6 which has the separation band 17 which can form the fracture | rupture part 30 of width.

  The example of FIG. 11 has the rupture force guiding portions 25 and 25 having a constant width as in the example of FIG. 7, has a bent portion as the inclined portion 32 at the center, and forms a wide rupture portion 33. This is Example 7 with a possible separation band 17. The example of FIG. 12 is an example 8 in which the inclined portion 32 has a bent portion, but the position thereof is asymmetrically arranged between the distal end portion of the breaking force guiding portion 25 having a certain width and the peripheral edge of the pack. .

  As described above, the wiping article 10 according to the present invention described so far can be used in combination with a heating means and a cooling means. In that case, the heating means is warmed by bringing the heating means into contact with the wet wiping article 10, or the cooling means is squeezed and cooled to bring the cooling means into contact with the wet wiping article 10. As the heating means, a warmer using a oxidizing action of iron powder called a disposable warmer or a single-use warmer is used. In addition, as an example of means for cooling and using the cooling means for cooling the wiping article 10 instead of the heating means and using it as a cooling means, a cold insulator filled with a chemical substance called a cooling pack, freezing point, etc. (for example, , Instant Cooling Pack “Cool Girl” related to Sankei Trading Co., Ltd. can be used. The heating means and reaction aid are, for example, iron powder and salt water, and the cooling means and reaction aid are, for example, a combination of ammonium nitrate and urea.

  The wiping product according to the present invention is used not only as a wiping product for wiping hands and face, but also as a wipe for sweat during sports, as a wiping body for elderly care, and for cleaning in a medical field. There is a possibility that it can be used for such purposes. It is also useful for taking measures while maintaining necessary and sufficient hygiene even when it is difficult to expect cleanliness, such as at the accident site. Furthermore, it can be used as a pack material for makeup by forming a sheet material into a shape to be affixed to the face.
