Description

[Technical field]

[0001] The present invention relates to an absorbent article for pets. [Background technology]

[0002] Disposable pet diapers for pets such as dogs and cats have been known for some time. As the number of pet owners has increased, the number of pet owners who keep pets indoors has also increased, and the use of disposable pet diapers has also increased. In addition, when taking pets out, people often put disposable pet diapers on them to prevent them from soiling the surroundings. Patent Document 1 discloses a belly-band-shaped paper diaper for male dogs, and states that this paper diaper can fit the dog's body by connecting both ends of the padding over the back with a belt to form a belly-band shape.

[0012] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of an absorbent article for pets according to the present invention will be described in detail with reference to the drawings. The pet absorbent article 1 according to this embodiment is to be worn by pets (for example, dogs, cats, etc.), and is particularly suitable for use with male pets. In this specification, wearing of the absorbent article for pets refers to a state in which the absorbent article for pets is wrapped around the body (torso) of an animal pet, regardless of whether it is before or after absorbing bodily fluids. The lateral direction (longitudinal direction) of the absorbent article for pets refers to the direction along the waist direction (circumferential direction) of the pet when the absorbent article for pets is worn, and is the direction along the arrow X in the figure. The width direction (front-rear direction) of the absorbent article for pets refers to the direction intersecting (orthogonal to) the longitudinal direction, and is the direction along the arrow Y in the figure. The thickness direction of the absorbent article for pets refers to the direction in which each component is laminated, and is the direction along the arrow Z in the figure. The skin side of the absorbent article for pets refers to the direction toward the body side of the pet when the absorbent article for pets is worn in the thickness direction, and the non-skin side refers to the direction opposite to the skin side in the thickness direction. The front-rear direction refers to the front-rear direction of the pet when the absorbent article for pets is worn. Bodily fluids mainly refer to urine.

[0013] Fig. 1 is a plan view of the non-skin side of the absorbent article for pets according to the first embodiment of the present invention. Fig. 2 is a cross-sectional view taken along the line II-II in Fig. 1. Fig. 3 is a cross-sectional view taken along the line III-III in Fig. 1. Fig. 4 is an explanatory view showing a modified example of a fixing part. Figs. 2 and 3 each show a schematic cross-section of the absorbent article for pets. Furthermore, each drawing does not stipulate the size relationship between the components of the absorbent article for pets, and the dimensions of each component can be appropriately selected from a wide range depending on the purpose of the absorbent article for pets, the type of pet for which it is used, etc.

[0014] As shown in Figures 1 to 3, this pet absorbent article 1 comprises a liquid-permeable top sheet 2 which is positioned relatively closer to the skin when the pet absorbent article 1 is worn on a pet, a liquid-impermeable back sheet 3 which is disposed opposite the top sheet 2 and which is positioned relatively closer to the skin when the pet absorbent article 1 is worn, an absorbent body 4 which is disposed between the top sheet 2 and the back sheet 3, at least a pair of three-dimensional gathers 5 which are provided on the skin-side surface of the top sheet 2 and arranged in the lateral direction, a mechanical hook tape (fastening portion) 6 which is provided at an end of the back sheet 3 in the longitudinal direction, and two fixing portions 7 which protrude from one end of the back sheet 3 in the width direction and to which the pet's legs are fixed.

[0015] The back sheet 3 has a resin film 12 that contacts the absorbent body 4 to prevent leakage of body fluids such as urine, and a nonwoven fabric portion 8 located on the non-skin side of the resin film 12. The nonwoven fabric portion 8 can also be provided so as to be located on a surface where the absorbent body 4 is not present. The fixing portion 7 is fixed to the back sheet 3 including the nonwoven fabric portion 8. Body fluids are absorbed and retained in the absorbent body 4 through the top sheet 2. The three-dimensional gathers 5 may be provided not only in the lateral direction but also in the width direction, so that the three-dimensional gathers 5 surround the absorbent body 4 on all sides.

[0016] Each component will be described below. (Top sheet) The top sheet 2 is a liquid-permeable sheet-like member that quickly passes bodily fluids toward the absorbent body 4, and is disposed opposite the back sheet 3 with the absorbent body 4 sandwiched therebetween. The top sheet 2 is in contact with the wearer's skin, and is preferably a substrate that has a soft feel and does not irritate the skin. The top sheet 2 may be formed from a substrate that has liquid permeability that allows bodily fluids to move toward the absorbent body 4. Examples of substrates for the top sheet 2 include hydrophilic sheets, composite nonwoven fabrics that are laminates of the same or different hydrophilic sheets, open-ended films such as open-ended polyethylene films, and foamed films such as polyethylene foam and urethane foam. Examples of hydrophilic sheets include air-through nonwoven fabrics, thermal bond nonwoven fabrics, spunlace nonwoven fabrics, spunbond nonwoven fabrics, and the like, which are made using synthetic fibers made of synthetic resins such as polypropylene and polyethylene, regenerated fibers such as rayon, and natural fibers such as cotton. Among these, nonwoven fabrics are preferred, and air-through nonwoven fabrics or spunbond nonwoven fabrics are more preferred from the viewpoint of texture.

[0017] The top sheet 2 may be embossed or perforated on its surface to improve liquid permeability. Any known method may be used for embossing or perforating the top sheet 2 without any restrictions. In addition, the top sheet 2 may contain lotion, antioxidant, anti-inflammatory component, pH adjuster, antibacterial agent, moisturizer, etc. to reduce irritation to the skin. The shape of the top sheet 2 is not particularly limited, and may be any shape that covers the absorbent body 4 to guide bodily fluids to the absorbent body 4 without leaking. The length in the width direction of the top sheet 2 of this embodiment is shorter than the length in the width direction of the absorbent article 1 for pets.

[0018] (Back seat) The back sheet 3 may be formed from a liquid-impermeable substrate so that the body fluid held by the absorbent 4 does not leak to the non-skin side, and is formed from a material such as a resin film or a composite sheet formed by laminating a resin film and a non-woven fabric. Of these, the back sheet 3 is preferably a composite sheet formed by laminating a resin film (film portion) 12 on the skin side and a non-woven fabric (non-woven fabric portion) 8 located on the non-skin side of the resin film 12, as shown in Figures 2 and 3.

[0019] Examples of the resin film 12 used in the back sheet 3, which is a composite sheet, include polyester, polyvinyl alcohol, polyethylene, polypropylene, and composite films of polyethylene and polypropylene. The nonwoven fabric portion 8 used in the back sheet 3, which is a composite sheet, is not particularly limited in its manufacturing method, and examples thereof include composite nonwoven fabrics obtained by laminating multiple identical and / or different types of nonwoven fabrics, such as spunbond nonwoven fabric, meltblown nonwoven fabric, spunbond nonwoven fabric / meltblown nonwoven fabric, and spunbond nonwoven fabric / meltblown nonwoven fabric / spunbond nonwoven fabric, and composite materials thereof.

[0020] It is preferable that the back sheet 3 has breathability to prevent stuffiness during wear. In order to provide the back sheet 3 with breathability, for example, a filler may be blended into the resin film 12 of the base material, or the back sheet 3 may be embossed. An example of the filler is calcium carbonate, and the blending method may be any known method without limitation. For example, a porous (breathable) resin film can be obtained by kneading a resin and a filler, forming the resulting kneaded product into a film, and removing the filler from the resulting film. The length in the width direction of the backsheet 3 in this embodiment is the same as the length L2 in the width direction of the absorbent article for pet 1 (see FIG. 6).

[0021] FIG. 6 is a plan view illustrating the dimensions of one example of an absorbent article for pets. The sizes (L1 to L8) of the individual components of the absorbent article for pet 1 are set according to the size of the pet that is expected to wear it. As shown in FIG. 6, the total lateral length L1 of the pet absorbent article 1 depends on the size of the pet, but to be generous, it is generally preferable that it be 300 mm or more and 570 mm or less, and the total widthwise length L2 of the pet absorbent article is preferably 180 mm or more and 350 mm or less.

[0022] (3D gathers 5) 1, the pet absorbent article 1 includes, for example, a pair of three-dimensional gathers 5 near both side edges of the skin side of the top sheet 2 along the lateral direction of the pet absorbent article 1. In this embodiment, one widthwise end of the three-dimensional gathers 5 is fixed near both side edges of the skin side of the back sheet 3, a widthwise intermediate portion is fixed near both side edges of the skin side of the top sheet 2, and the other widthwise end is a free end that is not fixed to the top sheet 2. Note that the three-dimensional gathers 5 are merely one example, and three-dimensional gathers of various shapes and configurations can be used.

[0023] The front and back three-dimensional gathers 5 are sheet-like members for preventing lateral leakage (leakage in the front-rear direction) of bodily fluids excreted by a pet wearing the pet absorbent article 1. The front and back three-dimensional gathers 5 are disposed on both sides in the width direction (Y direction) of the skin side of the top sheet 2, extend in the longitudinal direction, and are fixed to the top sheet 2. Note that the object to which the three-dimensional gathers 5 are fixed is not limited to the top sheet 2; for example, the three-dimensional gathers 5 may be fixed to the back sheet 3 in addition to the top sheet 2.

[0024] The sheet constituting the three-dimensional gathers 5 is a liquid-impermeable sheet having water-repellent and / or waterproof properties, and is composed of, for example, a nonwoven fabric. The nonwoven fabric used here is not particularly limited to any water-repellent and / or waterproof (liquid-impermeable) nonwoven fabric formed from hydrophobic fibers, and examples thereof include spunbond nonwoven fabric, meltblown nonwoven fabric, composite nonwoven fabric (SMS nonwoven fabric) which is a spunbond nonwoven fabric / meltblown nonwoven fabric / spunbond nonwoven fabric laminate, and composite nonwoven fabric (SMMS nonwoven fabric) which is a spunbond nonwoven fabric / meltblown nonwoven fabric / meltblown nonwoven fabric / spunbond nonwoven fabric laminate. Among these, an SMS nonwoven fabric is preferable.

[0025] Elastic stretchable members (not shown) may be provided on the front and back three-dimensional gathers 5. The elastic stretchable members may be arranged along the longitudinal direction of the front and back three-dimensional gathers 5 to impart standing ability to the front and back three-dimensional gathers 5. As the elastic stretchable member, for example, thread-, string- or band-shaped members made of natural rubber, synthetic rubber, polyurethane or the like may be appropriately used. Front and rear side gathers (not shown) may be provided along the longitudinal direction at both widthwise ends of the pet absorbent article 1. The front and rear side gathers provide stretchability to both widthwise ends of the pet absorbent article 1, improving the fit to the pet's body.

[0026] (Absorbent 4) The absorbent body 4 is disposed between the top sheet 2 and the back sheet 3, and absorbs and retains bodily fluids that have permeated through the top sheet 2. The shape of the absorbent body 4 is not particularly limited, and examples thereof include a rectangular shape, an oval shape, and the like. The absorbent body 4 may contain, for example, absorbent fibers and a highly absorbent polymer as an absorbent base material. 6, the lateral length L3 of the absorbent body 4 is preferably 100 mm or more and 370 mm or less. The widthwise length L4 of the absorbent body 4 is preferably 50 mm or more and 250 mm or less.

[0027] (Absorbent Fiber) The absorbent fiber is not particularly limited as long as it is generally used in absorbent articles such as sanitary napkins, paper diapers, and urine pads, and examples thereof include fluff pulp, cotton, rayon, acetate, tissue, absorbent paper, hydrophilic nonwoven fabric, etc. Among these, fluff pulp is preferred from the viewpoint of absorbency. Examples of fluff pulp include wood pulp (e.g., coniferous bleached kraft pulp (N-BKP) such as southern pine and Douglas fir), synthetic fiber, resin fiber, cotton-like defibrated material such as non-wood pulp, etc.

[0028] (Superabsorbent polymer) The superabsorbent polymer (hereinafter also referred to as "SAP") is not particularly limited as long as it can absorb body fluids and prevent backflow, and examples thereof include polyacrylates, polyaspartates, (starch-acrylic acid) graft copolymers, (acrylic acid-vinyl alcohol) copolymers, (isobutylene-maleic anhydride) copolymers, and saponification products thereof. Among these, from the viewpoint of the absorption amount per weight, polyacrylates are preferred, alkali metal polyacrylates are more preferred, and sodium polyacrylate is even more preferred. The superabsorbent polymers can be used alone or in combination of two or more.

[0029] The superabsorbent polymer is used in the form of particles, fibers, etc., for example, but is preferably used in the form of particles from the viewpoint of ease of handling, etc. In this case, by avoiding the use of a fine powder of superabsorbent polymer that has poor flowability as a powder and using a superabsorbent polymer having a medium particle size, it is possible to improve basic absorption performance and reduce the rough feel caused by the absorbent body 4 becoming hard.

[0030] The absorbent fibers and SAP in the absorbent body 4 may be in the form of a mixture of SAP particles in absorbent fibers, or may be in the form of a SAP sheet with SAP particles bonded between absorbent fibers. Another form of absorbent body 4 may be an absorbent sheet containing multiple hydrophilic nonwoven fabrics and a superabsorbent polymer bonded between the hydrophilic nonwoven fabrics.

[0031] (Absorbent paper) The entire absorbent 4 may be wrapped in absorbent paper (not shown). As the absorbent paper, any hydrophilic sheet commonly used in this field may be used, for example, hydrophilic nonwoven fabrics such as thermal bonded nonwoven fabrics, spunbonded nonwoven fabrics, airlaid nonwoven fabrics, air-through nonwoven fabrics, and pulp-containing nonwoven fabrics, tissue paper, absorbent paper, etc. Among hydrophilic nonwoven fabrics, hydrophilic nonwoven fabrics such as thermal bonded nonwoven fabrics, spunbonded nonwoven fabrics, air-through nonwoven fabrics, and pulp-containing nonwoven fabrics are more preferred, and tissue paper (crepe paper), spunbonded nonwoven fabrics that have been subjected to hydrophilic treatment as necessary, and the like are even more preferred.

[0032] (Liquid diffusion sheet) A liquid-permeable liquid diffusion sheet (not shown) may be provided between the top sheet 2 and the absorbent body 4. The liquid diffusion sheet diffuses bodily fluids from the top sheet 2 side and guides them to the absorbent body 4 side. Examples of the liquid diffusion sheet include nonwoven fabrics such as air-through nonwoven fabrics, point-bonded nonwoven fabrics, spunbonded nonwoven fabrics, melt-blown nonwoven fabrics, and composite nonwoven fabrics obtained by laminating spunbond / melt-blown or spunbond / melt-blown / spunbond. There are no particular limitations on the shape of the liquid diffusion sheet, but it is preferable that the liquid diffusion sheet has a shape that can completely cover the surface of the absorbent body 4 so that liquids such as urine are thoroughly diffused into the absorbent body 4.

[0033] (Fastening part 6) The fastening portion 6 is a part for fastening both longitudinal sides of the pet absorbent article 1 to each other when the pet absorbent article 1 is put on a pet, and is provided at one longitudinal end portion of the pet absorbent article 1. In this embodiment, a mechanical hook tape 6 is used as the fastening part 6. The mechanical hook tape 6 is fixed to the non-skin side of the back sheet 3 at one end in the longitudinal direction of the pet absorbent article 1 in a state of extending along the width direction. The mechanical hook tape 6 is a member having a plurality of hooks (not shown) on the non-skin side, and is a tape that is detachable from the top sheet 2. Note that the "mechanical hook tape" may also be called a "mechanical tape" or a "hook tape".

[0034] In addition, when the mechanical hook tape 6 is used as the fastening part 6 as in this embodiment, a loop material or the like may be fixed at a position corresponding to the mechanical hook tape 6. In addition, the fastening part 6 is not limited to the mechanical hook tape 6, and may be, for example, an adhesive layer made of a hot melt adhesive or an adhesive tape. In addition, in this embodiment, the fastening part 6 is provided on the non-skin side (non-skin side of the back sheet 3) of one end in the longitudinal direction of the absorbent article for pet 1, but is not limited thereto, and may be provided on the skin side of one end in the longitudinal direction of the absorbent article for pet 1. In this way, the fastening part 6 is configured to be able to take the connected state and the separated state any number of times so that it can be adjusted according to the size of the pet's waist. The fastening part 6 is often formed with a width in the lateral direction.

[0035] (Fixed part 7) Two fixing parts 7 are provided at one end (rear side) of the two widthwise ends of the back sheet 3. The horizontal positions of the two fixing parts 7 are arranged substantially symmetrically on either side of the center line (not shown) of the back sheet 3 in the horizontal (longitudinal) direction. During use, the two fixing parts 7 are inserted through the hind legs of a pet when the absorbent article for pet 1 is put on, and are fixed (held) around the legs.

[0036] The fixing part 7 is made of a material that is gentle on pets and has a strength that allows it to stably hold the pet's legs without breaking even when the pet walks through it after the pet has passed through it. Specifically, the fixing part 7 is made of a nonwoven fabric or cellulose fiber material, and the basis weight of this material is 70 g / m 2 More than 100g / m 2 It is preferable that the material is as follows: The material is easy to put on and gentle to the skin, and it is also preferable that the material is light, compact, and strong disposable paper diaper for pets. The connection portion between the base portion having the absorbent body 4 and the fixing portion 7 may be configured such that the base end of the fixing portion 7 is connected to the surface of the backsheet 3, or that the base end of the fixing portion 7 is sandwiched and connected between the nonwoven fabric of the backsheet 3 and the backsheet film.

[0037] Although the shape of the fixing part 7 is exemplified as a square shape in FIG. 1, various shapes can be appropriately adopted as long as the shape is large enough to insert the pet's legs and strong enough to hold the legs. The fixing part 7 is made of a nonwoven fabric that is a separate member from the nonwoven fabric part 8 of the back sheet 3. A configuration in which the fixing part 7 is attached as a separate member from the nonwoven fabric part 8 is easier to manufacture than an integrated type, and material costs are reduced. In addition, by making the material of the fixing part 7 as a leg insertion part from a material different from the nonwoven fabric part 8, it is easier to ensure the characteristics required for the fixing part 7 as needed. 6, the horizontal length L5 of the fixing part 7 is preferably 30 mm or more and 100 mm or less, and the width direction length L6 of the fixing part 7 is preferably 30 mm or more and 150 mm or less.

[0038] As shown in FIG. 4, the insertion shape portion 9 formed in the fixing portion 7 is preferably formed by any one of a cut-like slit, a perforation, or an opening 11 from the viewpoint of ease of molding. Fig. 4 is a diagram showing an example of the insertion shape portion 9. Fig. 4(a) shows an example in which the insertion shape portion 9 is configured by one line segment 10 formed by a slit or perforation extending horizontally or vertically, Fig. 4(b) shows an example in which the insertion shape portion 9 is configured by two intersecting line segments 10, and Fig. 4(c) shows an example in which the insertion shape portion 9 is configured by three intersecting line segments.

[0039] In Fig. 4(d), an opening 11 is provided, and the opening 11 has folds 13 protruding inward on each of the four sides of an assumed quadrangle, and has a shape like two Y-shapes connected horizontally. By providing multiple folds 13 around the opening 11 in this way, when a leg is inserted into the opening 11, the size of the opening 11 can be changed from the small area of ​​the foot to the locking position at the top of the leg, and the folds 13 that are changed by the insertion of the leg press the leg from the periphery, allowing the leg to be held comfortably. Note that the folds 13 are also formed when the insertion shape portion 9 is formed by multiple intersecting line segments 10 as in Fig. 4(b)(c).

[0040] Fig. 4(e) shows an example in which the opening 11 is formed in a square shape, and Fig. 4(f) shows an example in which the opening 11 is formed in a circular shape. The size of the opening 11 can be a fixed size or can be set according to the expected size of the pet. The fixing part 7 in which the opening 11 is formed is made of a flexible material such as nonwoven fabric, so that it can be held well on the leg as long as the size of the opening 11 is not set excessively large compared with the width (diameter) of the upper part of the pet's leg. 6, the lateral length L7 of the insertion shape portion 9 is preferably 10 mm or more and 80 mm or less, and the width direction length L8 of the insertion shape portion 9 is preferably 10 mm or more and 80 mm or less.

[0041] FIG. 5 is a diagram for explaining the ingenuity of the portions formed at both ends of the line segment of the slit or perforation when the insertion shape portion 9 is formed of a slit or perforation. As shown in Figures 5(a) and (b), both ends of line segment 15 constituting the slit or perforation are connected to other line segments in a direction intersecting the direction in which line segment 15 extends, thereby preventing tearing and improving the fit when the legs are put in. Note that the configuration in Figure 5(a) is an example in which short line segments 16 that intersect at right angles are connected to both ends of line segment 15 extending laterally, and Figure 5(b) is an example in which short line segment 17 that intersects with line segment 15 extending laterally at an angle θ of approximately 120° is provided on only one side.

[0042] Also, as shown in Fig. 5(c), a configuration can be adopted in which round holes 18 are formed at both ends of the line segment 15 that constitutes the slit or perforation. This configuration also prevents tearing and improves the fit by facilitating deformation of materials such as the nonwoven fabric portion 8 at both ends. Although a small round hole 18 is shown in Fig. 5(c), the size of the round hole can be set appropriately.

[0043] (How to use) Next, there will be described an example of a method of using the pet absorbent article 1. Note that the method of using the pet absorbent article 1 described below is just an example, and the article can also be used in other modes. Fig. 7 is an explanatory diagram showing a pet wearing the pet absorbent article 1 as viewed from the side. Fig. 8 is an explanatory diagram showing a pet wearing the pet absorbent article as viewed from behind.

[0044] As shown in Figs. 7 and 8, the absorbent article for pet 1 is attached to the waist of the pet 20 such that the longitudinal direction of the absorbent article for pet 1 is the circumferential direction of the waist of the pet 20 and the width direction is the front-rear direction of the pet 20. When attaching the absorbent article for pet 1 to the pet 20, first, the absorbent article for pet 1 is placed under the waist of the pet 20 with the top sheet 2 side facing the skin side of the pet 20 and the two fixing parts 7 on the rear side. Next, the hind legs 21 of the pet 20 are inserted through the two fixing parts 7, and both longitudinal ends of the absorbent article for pet 1 are lifted so as to cover the urination part of the pet 20 from below, and the absorbent article for pet 1 is wrapped around the waist of the pet 20. Then, while holding one longitudinal end of the absorbent article for pet 1 with a hand, the other end is pulled and tightened, and the other end is fastened by engaging with the mechanical hook tape (fastening part) 6 on the one end side. This allows the pet absorbent article 1 to be worn by the pet 20 when in use.

[0045] In the pet absorbent article 1 configured as described above, the two fixing portions 7 protruding from one widthwise side (rear side) of the nonwoven fabric portion 8 are provided with insertion-shaped portions 9, so that the fixing portions 7 are more likely to deform in response to the movement of the hind legs 21 than in a configuration in which the insertion-shaped portions 9 are formed in the nonwoven fabric portion 8 itself.

[0046] The pet absorbent article 1 according to this embodiment has the following advantages. In the configuration of this embodiment, the nonwoven fabric part 8 of the back sheet 3 constituting the absorbent article for pet 1 has no slits or holes, and a fixing part 7 protruding from the side of the nonwoven fabric part 8 is provided separately. This allows the pet to move its legs easily, and the nonwoven fabric part 8 is not rubbed by the movement of the legs as in the conventional case. This makes it less likely that skin rashes or tangled fur will occur due to rubbing with the nonwoven fabric part 8. For example, the pet absorbent article described in Patent Document 1 may rotate if the absorbent article does not fit the pet's body type and moves vigorously, but in this embodiment, the absorbent article is fixed to the legs by fixing portion 7 and will not rotate.

[0047] Furthermore, in the conventional configuration, when an owner puts the product of this embodiment on a pet, if the pet moves and it is difficult to put on the diaper, the pet may put it on loosely, which may cause the diaper to slip off. However, in the configuration of this embodiment, by attaching the fixing part 7, even if the diaper is put on loosely, since the diaper is provided with a part fixed to the leg, it is possible to prevent leakage of urine, etc., caused by the pet absorbent article 1 rotating and slipping off.

[0048] Even if the belt portion should come off, the insertion portion of the fixing portion 7 is shaped so that it is difficult for the absorber 4 to come off the pet's leg, and therefore the absorber 4 will not come off the pet's leg completely. Furthermore, since the fixing parts 7 protruding from the pet absorbent article 1 serve as a guide when putting on the pet, there is no misalignment between the position of the private parts and the absorbent body 4 when the pet is put on. Even after putting the pet absorbent article 1 on the pet, the protruding fixing parts 7 can move up and down and twist in response to the pet's movements independently of the back sheet 3, and can also deform laterally, so that the occurrence of inconveniences such as urinary leakage can be suppressed without causing excessive stress to the pet.

[0049] Although the present invention has been described above using the embodiments, it goes without saying that the technical scope of the present invention is not limited to the scope of the above embodiments, and it is clear to those skilled in the art that various modifications and improvements can be made to the above embodiments.
