Description

  The present invention relates to a finger sack. In particular, the present invention relates to a finger sack that can be used for cleaning and massaging teeth and gums.

  In order to prevent periodontal disease, strengthen gums, or prevent bad breath, it is preferable to clean the oral cavity after meals. For this reason, the mouth is usually brushed with a toothbrush to keep the oral cavity clean. However, it is often difficult to brush the teeth on the go, and it is often difficult for the sick to brush their teeth while lying down. Furthermore, it was often difficult for pet animals to watch out for toothbrushes and brush their teeth.

  Therefore, it has been proposed to use a finger sack instead of a toothbrush so that the oral cavity can be cleaned. For example, JP-A-9-220243 (Patent Document 1), JP-A-2005-334065 (Patent Document 2), JP-A-2001-245725 (Patent Document 3), JP-A-4-104922 (Patent) Document 4) proposes a finger sack that can clean the oral cavity. Specifically, finger sac made by using Japanese paper, a cotton nonwoven fabric produced by a water jet method, a spun bond nonwoven fabric, or a heat-shrinkable nonwoven fabric is disclosed as these finger sac. ing. However, these finger sacks have not been sufficiently cleaned, such as being difficult to clean up to the gap between the teeth.

  Also, when using such a finger sack, the inserted finger is bent or stretched for cleaning, etc., but these conventional finger sacks are hard and difficult to bend, so they are inferior in operability such as cleaning. In some cases, the nonwoven fabric itself or the joint between the nonwoven fabrics may break.

  Furthermore, when a finger thick person inserts a finger into such a finger sack, the finger sack is not extensible and difficult to wear, and in some cases, the finger sack may break during wearing or use. there were.

(First aspect)
FIG. 1 is a schematic plan view on the cleaning nonwoven fabric side, FIG. 2 is a schematic plan view on the back nonwoven fabric side, and a schematic side view of the finger sack of the present invention with the finger sack attached to a finger. 3 will be described.

  The finger sack (first aspect) in FIGS. 1 to 3 is composed of a spunbonded nonwoven fabric having a hydroxyapatite powder P supported on the surface so that it can be brought into contact with teeth in the oral cavity, gums and the like to perform a cleaning action. The cleaning nonwoven fabric 1 and the back surface nonwoven fabric 2 which consists of a hydroentangled nonwoven fabric are joined by the U-shaped melt | fusion part F along the outer periphery. The cleaning nonwoven fabric 1 is formed with four folds G1 to G4, and the mountain fold lines PL1 to PL4 of the folds G1 to G4 all extend in a direction orthogonal to the length direction of the finger sack.

  In the state of the finger sack in FIGS. 1 to 3, the cleaning nonwoven fabric 1 and the back nonwoven fabric 2 in a state having four folding folds G1 to G4 are both linearly extended first side edge E1 (upper side in FIG. 1). Outer edge), connected to the first side outer edge E1, and convexly curved base outer edge E2 (left outer edge in FIG. 1), connected to the base outer edge E2, and the second side extending linearly The outer edge E3 (the lower outer edge in FIG. 1) and the insertion-side outer edge Ei (the right outer edge in FIG. 1) connected to the second side outer edge E3 and the first side outer edge E1 and curved in a concave shape on the bottom outer edge E2 side. A bell-like shape having an outer peripheral edge made of

  Moreover, in the state of the finger sack in FIGS. 1-3, the cleaning nonwoven fabric 1 and the back surface nonwoven fabric 2 of the state which has four folds G1-G4 have the same magnitude | size. Therefore, in the stage before inserting a finger, the cleaning nonwoven fabric 1 and the back nonwoven fabric 2 in a state having four folding folds G1 to G4 are in a completely overlapped state.

  Further, in FIG. 1 (cleaning nonwoven fabric 1 side), the fusion part F is a first side fusion welded in a straight line parallel to the first side outer edge E1 of the cleaning nonwoven fabric 1 and spaced apart by a certain distance. Part F1, connected to the first side fusing part F1, parallel to the bottom outer edge E2 of the cleaning nonwoven fabric 1, spaced apart by a certain distance, curved fusing part F2, the bottom fusing It is connected to the wearing part F2, and is composed of a second side-side fused part F3, which is parallel to the second side edge outer edge E3 of the cleaning nonwoven fabric 1 and is linearly fused with a certain distance. .

  Note that neither the first side fusing part F1 nor the second side fusing part F3 extends to the insertion side outer edge Ei of the cleaning nonwoven fabric 1 and has four folds G1 to G4. It has a length of about two thirds of the length (about 96 mm) of the first side outer edge E1 or the second side outer edge E3 of the nonwoven fabric 1. Further, the end F1e (the right end in FIG. 1) of the first side fusing part F1 is separated from the end F3e (the right end in FIG. 1) of the second side fusing part F3 by about 30 mm.

  The finger sack of FIGS. 1 to 3 has the above-described configuration, and a hollow portion can be formed by spreading the insertion-side outer edge Ei of the cleaning nonwoven fabric 1 and the back nonwoven fabric 2 away from each other. When the finger is inserted so that the ventral side of the finger 3 becomes the side of the cleaning nonwoven fabric 1 having four folding folds G1 to G4 in the hollow portion, as shown in FIG. 3, the folds of the folding folds G1 to G4 are slightly Eyes PL1-PL4 will be in the state where it protruded. Therefore, when performing the cleaning operation, for example, if the mountain fold lines PL1 to PL4 of the folds G1 to G4 are positioned between the teeth, the mountain fold lines PL1 to PL4 are between the teeth. Therefore, it is easy to clean. Moreover, since the edges of the mountain crease lines PL1 to PL4 can be used, the cleaning property is excellent even if it is not between the teeth.

  In addition, since the hydroxyapatite powder P is carried on the cleaning nonwoven fabric 1, it not only has excellent cleaning properties, but also promotes the formation of self-bones, exhibits high adsorptivity of bacteria, etc., or teeth It exerts effects such as imparting acid resistance to. Therefore, it can be suitably used for cleaning the oral cavity.

  In addition, neither the first side fusing part F1 nor the second side fusing part F3 of the fusing part F extends to the insertion side outer edge Ei of the cleaning nonwoven fabric 1, and the first from the insertion side outer edge Ei. Since the region from the end F1e of the side fusing part F1 to the end F3e of the second side fusing part F3 can be freely expanded, the insertability of the finger 3 is excellent.

  More specific description will be given below.

  A spunbond nonwoven fabric having a hydroxyapatite powder P supported on the surface is used as the cleaning nonwoven fabric 1 and is folded so as to have four folds G1 to G4. That is, the cleaning nonwoven fabric 1 extends from the bottom outer edge E2, and has a mountain fold line PL1 extending in a direction perpendicular to the length direction of the finger sack as a mountain to fold back toward the bottom outer edge E2 to form a fold G1. The valley fold line PL1 ′ extending in the direction perpendicular to the length direction of the fold is used as a valley, folded back to the insertion-side outer edge Ei side, and further, the mountain fold line PL2 extending in the direction perpendicular to the length direction of the finger sack is taken as a mountain. The folding fold G2 is formed by folding back to the E2 side. Similarly, a crease G3 is formed with a valley fold line PL2 ′ extending in a direction perpendicular to the length direction of the finger sack as a valley and a mountain fold line PL3 extending in a direction perpendicular to the length direction of the finger sack as a mountain. A fold G4 is formed with a valley fold line PL3 ′ extending in a direction perpendicular to the length direction of the sack as a valley and a mountain fold line PL4 extending in a direction perpendicular to the length direction of the finger sack as a mountain, and the length of the finger sack is formed. The cleaning nonwoven fabric 1 extends to the insertion side outer edge Ei with a valley fold line PL4 ′ extending in a direction orthogonal to the direction as a valley. Therefore, when the finger is inserted so that the belly side of the finger 3 becomes the cleaning nonwoven fabric 1 side, the mountain fold lines PL1 to PL4 of the folds G1 to G4 slightly protrude as shown in FIG. Is excellent.

  In addition, as shown in FIG. 1, the mountain fold lines PL <b> 1 to PL <b> 4 are on the insertion side outer edge Ei side, and the valley fold line PL <b> 1 ′ to PL <b> 4 ′ on the bottom side outer edge E <b> 2 side. Since the fingertip can be inserted without being caught by the folds G1 to G4, the wearability is excellent. However, if not worrying about the wearability, unlike FIG. 1, the mountain crease lines PL1 to PL4 may be on the bottom outer edge E2 side, and the valley crease lines PL1 ′ to PL4 ′ may be on the insertion side outer edge Ei side. .

  In addition, although the cleaning nonwoven fabric 1 in FIG. 1 has four folds G1-G4, it does not need to be four and may be 1-3 or 5 or more. Moreover, although the space | interval with the space | interval (PL1-PL1 ', PL2-PL2', PL3-PL3 ', PL4-PL4') of a mountain crease line and an adjacent valley crease line is not specifically limited, folds G1- It is preferable that it is 3 mm-12 mm so that the mountain fold line PL1-PL4 of G4 may protrude moderately, and it may be excellent in cleaning property. Further, the distance between the crease lines (PL1-PL2, PL2-PL3, PL3-PL4) is not particularly limited, but is preferably 3 mm to 15 mm so as to be excellent in cleanability.

  Furthermore, the cleaning nonwoven fabric 1 in FIG. 1 extends in the direction in which the mountain fold lines PL1 to PL4 and the valley fold lines PL1 ′ to PL4 ′ of the folds G1 to G4 are orthogonal to the length direction of the finger sack. -PL4 and valley crease lines PL1'-PL4 'do not need to extend in the orthogonal direction. If the mountain fold lines PL1 to PL4 or the valley fold lines PL1 'to PL4' extend in a direction intersecting with the length direction of the finger sack, the same effects are obtained. The “finger sack length direction” in the present invention refers to a direction parallel to the finger insertion direction Id.

The cleaning nonwoven fabric 1 in FIG. 1 is composed of a spunbonded nonwoven fabric carrying a hydroxyapatite powder P on its surface, but this spunbonded nonwoven fabric is not stretchable and is therefore suitable for effective cleaning without stretching during cleaning. is there. Hydroxyapatite is basic calcium phosphate represented by the chemical formula Ca ₁₀ (PO ₄ ) ₆ (OH) ₂ .

  In FIG. 1, a spunbond nonwoven fabric is used, but instead of the spunbond nonwoven fabric, for example, a fiber sheet such as a woven fabric, a knitted fabric, a chemical bond nonwoven fabric, a thermal bond nonwoven fabric, a needle punched nonwoven fabric, or a hydroentangled nonwoven fabric is used. be able to. When the finger sack of the present invention is used for oral cleaning, the cleaning nonwoven fabric 1 is a spunbond nonwoven fabric or thermal bond nonwoven fabric so that unintended chemical substances do not enter the body of the user (human, pet animal, etc.). Or it is preferable that it is a hydroentangled nonwoven fabric.

  In addition, since the cleaning nonwoven fabric 1 carries the hydroxyapatite powder P, the cleaning nonwoven fabric 1 not only has excellent cleaning properties, but also promotes the formation of self-bones, exhibits high adsorptivity of bacteria, etc., or teeth It exerts effects such as imparting acid resistance to. Therefore, it can be suitably used for cleaning the oral cavity.

  The hydroxyapatite powder P is preferably fired. It is because even if it is a case where it uses for a cleaning use by baking, it does not collapse by friction and it is easy to exhibit the said function over a long period of time. Moreover, it is preferable that the hydroxyapatite powder P is spherical so that the touch is excellent. Furthermore, the particle diameter of the hydroxyapatite powder P is not more than one-third of the average fiber diameter of the fibers constituting the fiber sheet (in FIG. 1, the spunbond nonwoven fabric) so that it does not easily fall off from the fiber sheet such as the spunbond nonwoven fabric. Is preferred.

  As described above, in FIG. 1, the hydroxyapatite powder P is supported. However, in addition to or instead of the hydroxyapatite powder P, a functional powder may be supported. Examples of such functional powder include abrasives (eggshell, hydrous silicic acid, titanium oxide, heavy calcium carbonate, silica, calcium carbonate, calcium pyrophosphate, calcium dihydrogen phosphate, anhydrous silicic acid, calcium hydrogen phosphate. , Calcium dihydrogen phosphate, etc.) Fluorine compound powders (for example, sodium monofluorophosphate and sodium fluoride) with functions of strengthening and remineralizing teeth, powders that promote anti-inflammatory effects (tranexamic acid, ε- Aminocaproic acid, dipotassium glycyrrhizinate, β-glycyrrhetinic acid, etc.), powders that promote astringency (such as sodium chloride), and powders that suppress hypersensitivity (such as aluminum lactate and potassium nitrate).

  When such functional powder (including hydroxyapatite powder P) is supported by a binder, the surface of the functional powder is covered with the binder, and the function tends to be reduced or cannot be exhibited. The functional powder is preferably supported by fusing fibers constituting a cleaning fiber sheet (spunbond nonwoven fabric in FIG. 1). As a supporting method by fusing the fibers, a method disclosed in Japanese Patent Application Laid-Open No. 2004-3070 is preferable. In other words, a functional sheet heated to a temperature higher than the melting point of the thermoplastic resin is brought into contact with a fiber sheet (spunbond nonwoven fabric in FIG. 1) containing fibers made of thermoplastic resin on the surface, and the thermoplastic resin It is preferable to support the functional powder by fusing.

  In FIG. 1, the hydroxyapatite powder P is carried on the entire surface of the cleaning nonwoven fabric 1, but the end F1e of the first side fusing part F1 and the end F3e of the second side fusing part F3 are connected. It may be carried only in an area related to cleaning or the like, such as being carried only in the area having the fusion part F (the left area in FIG. 1) with respect to the straight line formed by tying. It is not a thing.

  On the other hand, since the back surface nonwoven fabric 2 in FIG. 2 is made of a hydroentangled nonwoven fabric, unintended chemical substances do not enter the body of the user (human, pet animal, etc.), and the touch is also excellent.

  The fibers constituting the hydroentangled nonwoven fabric are not particularly limited. For example, recycled fibers such as rayon, semi-synthetic fibers such as acetate, nylon, vinylon, vinylidene, polyvinyl chloride, polyester, acrylic, polyolefin ( Polyethylene, polypropylene, etc.), synthetic fibers such as polyurethane and elastomer, and vegetable fibers such as cotton. In addition, the fiber does not need to be comprised from one component resin, and may be comprised from resin more than two components. Particularly, a composite fiber in which a plurality of resins having different heat shrinkage rates are combined, more specifically, a fiber having an eccentric core-sheath structure or a side-by-side structure made of polyester-low-melting point polyester or polypropylene-ethylene-propylene copolymer. Is a highly crimped fiber having a number of crimps of 50 (number / 25.4 mm, a value obtained by the method defined in JIS L1015: 2010 8.12.1 crimp number) or more by expressing crimps. The hydroentangled nonwoven fabric containing such highly crimped fibers (preferably containing 50 mass% or more, more preferably containing 80 mass% or more, and more preferably containing 90 mass%) has excellent extensibility and is soft to the touch In addition, since it has elasticity, it is suitable because it has excellent adhesion to the inserted finger 3.

  The back surface nonwoven fabric 2 in FIG. 2 does not need to be a hydroentangled nonwoven fabric, and may be a fiber sheet such as a woven fabric, a knitted fabric, a spunbond nonwoven fabric, a chemical bond nonwoven fabric, a thermal bond nonwoven fabric, or a needle punched nonwoven fabric. Similarly to the cleaning nonwoven fabric 1, the back nonwoven fabric 2 is preferably a spunbond nonwoven fabric, a thermal bond nonwoven fabric, or a hydroentangled nonwoven fabric so that unintended chemical substances do not enter the body of the user (human, pet animal, etc.). .

  In addition, since both the cleaning nonwoven fabric 1 and the back surface nonwoven fabric 2 are generally white sheets, the cleaning nonwoven fabric 1 and the back surface nonwoven fabric 2 tend to be difficult to distinguish. It is preferable to have a mark that can be recognized. For example, the cleaning nonwoven fabric 1 and / or the back surface nonwoven fabric 2 are of different colors, and the cleaning nonwoven fabric 1 and / or the back surface nonwoven fabric 2 are printed with figures, characters, patterns, etc., to have different surface states. 1 and / or the back nonwoven fabric 2 can be provided with irregularities by embossing or the like, so as to have different surface states.

  Further, when the finger sack of the present invention is used for cleaning in the oral cavity, the cleaning nonwoven fabric 1 and the back nonwoven fabric 2 are wetted by the saliva secreted, and as a result, the inserted finger gets wet and the oral cavity is infected. In order to prevent secondary infection due to the attachment of an infection source to the finger, the inside of the cleaning nonwoven fabric 1 and / or the back nonwoven fabric 2 (contact with the finger) A film which does not transmit liquid can be laminated on the side).

  The composition of this film can be selected arbitrarily. For example, polyethylene (high density polyethylene, medium density polyethylene, low density polyethylene, etc.), polyvinyl chloride, polyvinylidene chloride, polyvinyl alcohol, polypropylene (biaxially oriented polypropylene, nonaxially oriented) Polypropylene), polyester (polyethylene terephthalate, polytetraethylene terephthalate, polybutylene terephthalate, etc.), polylactic acid, polyurethane, polycarbonate, polystyrene, polyacrylonitrile, ethylene vinyl acetate copolymer, ethylene-vinyl alcohol copolymer, ethylene-methacryl Acid copolymers, nylon, cellophane, etc. can be used. The film is preferably a polyurethane resin or a polyolefin elastomer resin so that the operability of the finger sack is excellent.

  In addition, the method of laminating a film can be carried out by a conventionally known method. For example, dry lamination in which the film and the cleaning nonwoven fabric 1 or the back surface nonwoven fabric 2 are laminated with an adhesive, the cleaning nonwoven fabric 1 or the back surface nonwoven fabric 2 Examples include a direct laminate in which a molten resin is laminated on the film to directly form a film. However, it is not limited to these known methods.

  In the finger sack of FIGS. 1-3, since the cleaning nonwoven fabric 1 and back nonwoven fabric 2 which have a bell-shaped external shape are joined by the U-shaped melt | fusion part F along the outer periphery, the cleaning nonwoven fabric 1 and The finger 3 can be inserted into a hollow portion formed by spreading the insertion side outer edge Ei of the back nonwoven fabric 2 outward. However, as long as the finger 3 can be inserted, the outer shapes of the cleaning nonwoven fabric 1 and the back nonwoven fabric 2 do not need to be bell-shaped. For example, it may be rectangular, trapezoidal, or semi-elliptical.

  1 to 3, the U-shaped fusion part F has a constant thickness from the end F1e of the first side fusing part F1 to the end F3e of the second side fusing part F3. However, the thickness of the fused portion need not be constant. For example, the vicinity of the end F1e of the first side fusing portion F1 and / or the end F3e of the second side fusing portion F3 (for example, the end F1e of the first side fusing portion F1 or the second side fusing) In the range of about 5 mm from the end F3e of the part F3), by increasing the thickness of the fused part (for example, twice), it is possible to make it difficult for the finger sack to come off the finger during an operation such as cleaning.

  In addition, it is independent from the fusion | fusion part F which joins the cleaning nonwoven fabric 1 and the back surface nonwoven fabric 2, rather than the terminal F1e of the 1st side edge fused part F1, and / or the terminal F3e of the 2nd side edge fused part F3. By providing a fusion part (for example, a length of about 5 mm) slightly inside, it is possible to make it difficult for the finger sack to come off the finger during operations such as cleaning.

  Moreover, in the finger sack of FIGS. 1-3, when forming a hollow part and inserting a finger | toe, when it assumes that neither the cleaning nonwoven fabric 1 nor the back surface nonwoven fabric 2 deform | transforms, the cleaning nonwoven fabric 1 and the back surface nonwoven fabric 2 Can cover the finger with the same area, but as long as the finger 3 can be inserted by forming a hollow portion, it does not have to be the same area. For example, when it assumes as mentioned above, the cleaning nonwoven fabric 1 and the back nonwoven fabric 2 can cover a finger by the area ratio of 1: 4-4: 1. However, in consideration of the cleaning properties of the folding folds G1 to G4 by the cleaning nonwoven fabric 1, when the above assumption is made, the cleaning nonwoven fabric 1 and the back nonwoven fabric 2 cover the fingers at an area ratio of 1: 1 to 3: 1. It is preferred that it be possible.

  In addition, in the finger sack of FIGS. 1-3, although comprised from the two types of fiber sheets of the cleaning nonwoven fabric 1 and the back surface nonwoven fabric 2, it is not necessary to comprise from two types of fiber sheets. For example, it can be comprised from one type of fiber sheet which has a crease, and can be comprised from three or more types of fiber sheets.

  Moreover, in the finger sack of FIGS. 1-3, the hydroxyapatite powder P is carry | supported only by the cleaning nonwoven fabric 1, and it is not carry | supported by the back surface nonwoven fabric 2, However, The back surface nonwoven fabric 2 also has a hydroxyapatite powder etc. If the functional powder is supported, the back nonwoven fabric 2 can also be used as a cleaning nonwoven fabric.

  Further, the fusion part F in the finger sack of FIGS. 1 to 3 has a U-shape that is spaced apart from the first side outer edge E1, the bottom outer edge E2, and the second side outer edge E3 by a certain distance. It does not have to be a U-shape. For example, it is not necessary to be parallel to the first side outer edge E1, the bottom outer edge E2, and / or the second side outer edge E3, and the first side edge fused portion F1, the bottom side fused portion F2, and / or the second The distance between the side fusion part F3 and the first side outer edge E1, the bottom outer edge E2, or the second side outer edge E3 may change continuously or discontinuously. Further, the first side fusing portion F1, the bottom fusing portion F2, and / or the second side fusing portion F3 are separated from the first side outer edge E1, the bottom outer edge E2, or the second side outer edge E3. However, it may be fused including the first side outer edge E1, the bottom outer edge E2, and / or the second side outer edge E3. Further, since the finger can be fixed only by the first side fusing part F1 and the second side fusing part F3, the bottom fusing part F2 is not necessary.

  Further, in the finger sack of FIGS. 1 to 3, neither the first side fusing part F1 nor the second side fusing part F3 extends to the insertion side outer edge Ei of the cleaning nonwoven fabric 1, The lengths of the side-side fused portion F1 and the second side-side fused portion F3 are approximately two-thirds of the length of the first side-side outer edge E1 and the second side-side outer edge E3. There is no need for such fusion. For example, the length of the first side fusion part F1 and / or the second side fusion part F3 may extend to the insertion side outer edge Ei of the cleaning nonwoven fabric 1, or may not extend. The length does not have to be about two-thirds of the length of the first side outer edge E1 and the second side outer edge E3. The lengths of the first side fusing part F1 and the second side fusing part F3 correspond to the insertion length of the finger 3, so that the first side has excellent adhesion to the finger 3 of the finger sack. The lengths of the side fusion part F1 and the second side side fusion part F3 are preferably 30 mm to 60 mm in consideration of the length of a finger from a child to an adult.

  Further, in FIGS. 1 to 3, the distance between the end F1e of the first side fusing portion F1 and the end F3e of the second side fusing portion F3 is half of the outer circumference of the finger to be inserted (usually the index finger). Corresponds to the length. Therefore, the distance between the end F1e of the first side fusing part F1 and the end F3e of the second side fusing part F3 is preferably adjusted as appropriate by the user. For example, when a general adult male is assumed to be a user, the thickness is preferably 30 to 35 mm.

  Furthermore, in FIGS. 1-3, although the cleaning nonwoven fabric 1 and the back surface nonwoven fabric 2 are joined by the melt | fusion part F, it is not necessary to be joined by the melt | fusion part F. FIG. For example, it may be joined by sewing, or may be joined by an adhesive action of an adhesive such as hot melt.

  Furthermore, the finger sack of the present invention can be suitably used for cleaning of the oral cavity, but it is for cleaning around the ears and between fingers, for nail brushing, and for cosmetics (blotting, massage, remake, etc.) It can also be suitably used as a finger sack for cleaning jewelry and for cleaning screens of smartphones and the like. It can also be used as a finger sack when turning paper.

  The finger sack as shown in FIGS. 1 to 3 can be manufactured as follows, for example.

  First, after the cleaning nonwoven fabric 1 manufactures or prepares a spunbond nonwoven fabric by a conventional method, for example, the hydroxyapatite powder P is supported on the spunbond nonwoven fabric by the method disclosed in JP-A-2004-3070. . That is, the hydroxyapatite powder P heated to a temperature higher than the melting point of the thermoplastic fiber constituting the spunbond nonwoven fabric is brought into contact with the spunbond nonwoven fabric, and the hydroxyapatite powder P is supported by fusion of the thermoplastic fibers. Let Subsequently, the spunbond nonwoven fabric carrying the hydroxyapatite powder P is formed with a desired number of creases at a desired interval by a pleating machine such as that used in clothing.

  On the other hand, a hydroentangled nonwoven fabric is produced from the back nonwoven fabric 2 by the hydroentanglement method.

  Then, after the cleaning nonwoven fabric 1 having the folds G1 to G4 and the back nonwoven fabric 2 are overlapped, they are fused and joined (formed with a fusion part F) in a U shape by ultrasonic waves or the like, and then fused. A finger sack as shown in FIGS. 1 to 3 can be manufactured by punching out the outer side slightly from the fusion part F in a bell shape in parallel with the part F.

(Second aspect)
The finger sac in FIGS. 1 to 3 is an embodiment in which the cleaning nonwoven fabric 1 has creases, but the back nonwoven fabric 2 may have creases instead of or in addition to the cleaning nonwoven fabric 1. As an example, FIG. 4 is a schematic plan view of the back nonwoven fabric side of a finger sack (second embodiment) composed of a cleaning nonwoven fabric 1 having no folds and a back nonwoven fabric 2 having folds G1 to G5. FIG. 5 shows a schematic side view of the finger sack attached to the finger. In the finger sack of this 2nd aspect, the back fold nonwoven fabric which the mountain fold line PL1-PL5 and valley fold line PL1'-PL5 'of the creases G1-G5 are extended in the direction orthogonal to the length direction of a finger sack is provided. Therefore, as shown in FIG. 5, when the finger is inserted so that the fingernail side is the back nonwoven fabric side having the folds G1 to G5, and the finger is bent and cleaning or the like is performed, the folds G1 to G1 Since the part where the G5 is folded (the part between the mountain fold lines PL1 to PL4 and the valley fold lines PL1 ′ to PL4 ′) can be exposed, it is easy to bend and can follow the movement of the finger. It has the feature of being excellent.

  In the second embodiment, the back nonwoven fabric has five folds, and the number of folds is different from the cleaning nonwoven fabric having four folds in the first embodiment. This is because it is easy to follow the movement of the finger and is excellent in operability by extending to the second joint of the finger. Thus, the number of folds can be set as appropriate.

  The difference between the second aspect and the first aspect is that the cleaning nonwoven fabric 1 does not have creases and the back nonwoven fabric 2 has creases, and the number of creases in the back nonwoven fabric 2 is different. However, the other points can be the same as those in the first embodiment, and similar modifications are possible.

(Third aspect)
The finger sac in FIGS. 1 to 3 is an aspect in which the mountain fold lines PL1 to PL4 and the valley fold lines PL1 ′ to PL4 ′ of the folds G1 to G4 in the cleaning nonwoven fabric 1 extend in a direction perpendicular to the length direction of the finger sack. The mountain fold lines PL1 to PL4 or the valley fold lines PL1 ′ to PL4 ′ do not need to extend in the orthogonal direction. As an example, FIG. 6 shows a schematic plan view of the cleaning nonwoven fabric 1 in which the fold crease lines PL1 to PL4 and the valley fold lines PL1 ′ to PL4 ′ of the cleaning nonwoven fabric 1 extend in a direction parallel to the length direction of the finger sack. .

  In this 3rd aspect, since the mountain fold line PL1-PL4 and valley fold line PL1'-PL4 'of the crease in the cleaning nonwoven fabric 1 are extended in the direction parallel to the length direction of a finger sack, such a cleaning nonwoven fabric When the finger is inserted into the finger sack with 1, the part where the folds are folded (the part between the mountain crease lines PL1 to PL4 and the valley crease lines PL1 'to PL4') can be exposed. Even if a finger is inserted, it is easy to insert, and the finger sack does not break when worn or used.

  In addition, when a finger is inserted into the finger sack of the third aspect so that the belly side of the finger becomes the cleaning nonwoven fabric 1 side having a fold, the crease line of the fold is slightly protruded. Since the mountain fold lines PL1 to PL4 can be reached deeply between the teeth, the cleaning performance is excellent. Moreover, since the edge of this mountain fold line PL1-PL4 can be used, it is excellent in the cleaning property even if it is other than between teeth.

  The difference of the third aspect from the first aspect is in the direction in which the crease fold lines PL1 to PL4 and the valley crease lines PL1 ′ to PL4 ′ extend in the cleaning nonwoven fabric 1, and the other aspects are the first aspect. And similar modifications are possible.

(4th aspect)
The finger sac in FIGS. 1 to 3 is an aspect in which the fold crease lines PL1 to PL4 and the valley crease lines PL1 ′ to PL4 ′ of the cleaning nonwoven fabric 1 extend in a direction perpendicular to the length direction of the finger sack. PL1 to PL4 or valley fold lines PL1 ′ to PL4 ′ do not need to extend in the orthogonal direction. As another example, the back nonwoven fabric 2 has a crease, and a schematic plan view of the back nonwoven fabric 2 in which the mountain fold lines PL1 to PL4 and the valley fold lines PL1 ′ to PL4 ′ extend in a direction parallel to the length direction of the finger sack. Is shown in FIG.

  Also in this 4th aspect, like the 3rd aspect, the crease crease lines PL1-PL4 and the valley crease lines PL1'-PL4 'in the back nonwoven fabric 2 extend in a direction parallel to the length direction of the finger sack. Therefore, when a finger is inserted into the finger sack provided with such a back nonwoven fabric 2 so that the fingernail side is the back nonwoven fabric side having folds, the folded portions of the folds (mountain fold lines PL1 to PL4) And the valley crease lines PL1 ′ to PL4 ′) can be exposed, so that even if a thick finger inserts a finger, it is easy to insert, and the finger sack does not break when worn or used. Have.

  In addition, when the finger is inserted so that the fingernail side is the back nonwoven fabric side having the crease, and the finger is bent and an operation such as cleaning is performed, the folded part of the crease (the mountain fold lines PL1 to PL4 and Since the portion between the valley fold lines PL1 ′ to PL4 ′ can be exposed, it is easy to bend and can follow the movement of the finger, so that it has excellent operability.

  The difference between the fourth mode and the first mode is that the back nonwoven fabric 2 has creases, and the mountain fold lines PL1 to PL4 and the valley fold lines PL1 ′ to PL4 ′ are parallel to the length direction of the finger sack. The other points are the same as those of the first embodiment, and the same modifications are possible.
