Description

  The present invention relates to a domestic nipple marking sheet for labeling an animal suffering from the disease in advance so as not to milk from an inflamed site such as mastitis or papillitis in milking animals such as cows and goats.

  When milking dairy cows, mastitis is one of the most problematic diseases. When mastitis becomes severe, it must be used as a waste cow, and is ranked first or second as a reason for waste cow every year. In addition, even if it does not lead to discontinued cattle, mastitis results in a decrease in milk yield and deterioration of milk components. In addition, milk is shipped according to laws and regulations during the period of treatment for mastitis with antibiotics. It can't be done, and it has a big economic impact on dairymen.

  It is said that 5-10% of dairy cows are infected with mastitis. Currently, in order to distinguish between normal dairy cows and dairy cows infected with mastitis, it is normal to spray colored spray near the breast affected by mastitis or to attach a rubber band to the nipple. Differentiate from cows. However, the colored spray may be discolored before the work is completed or finished, and the nipple is a straw, so that there is a possibility that the milking machine is mistakenly attached and milked. In addition, the method of attaching a rubber band or the like is inferior in workability, is troublesome to attach and detach, and has a risk of restraining and damaging the nipple or exacerbating papillitis. Milking is a heavy labor due to the nature of handling so many cattle, and there are still accidents involving milk from cows infected with normal milk. Infected cow milk is unsuitable as a beverage and is disposed of as a dairy farmer.

  Conventionally, there is known a nipple protecting material for livestock that is waterproof and can be wound and fixed, and is made of a flexible film having a certain elongation rate (for example, Patent Document 1). Patent Document 1 proposes a nipple protecting material capable of treating or preventing nipple (breast) inflammation such as mastitis and papillitis in milking animals such as dairy cows. The teat protection material is intended for treatment or prevention. In Patent Document 1, it is possible to attach a milking machine after the nipple protection material is pasted on the nipple, and it is not necessary to replace each time milking, and it can be continued for several days to several weeks. Are listed. However, in practice, if milking is performed with the teat protection material wrapped around the teat, the quality of the milked product may be lowered by embracing the air. There are concerns such as rubbing and peeling off the nipple protection material. In addition, when a film having poor moisture permeability is continuously applied for several days to several weeks, there is generally a problem that stress on the skin becomes excessive, and skin respiration is disturbed and skin irritation is likely to occur. In addition, since the nipple protecting material according to Patent Document 1 employs a flexible film, if it is directly applied to a domestic animal's nipple, moisture permeability may not be sufficient, and skin irritation may occur. In addition, flexible films have poor visibility, and it is difficult for dairymen to distinguish between infected and non-infected animals without coloring.

A gel-like nipple pack that protects the nipple from bacteria, dirt, excrement, and the like is also known (for example, Patent Document 2). Specifically, in Patent Document 2, a pack is formed on the teat by applying a liquid containing alginate to the teat and allowing it to gel. Even the method described in Patent Document 2 does not have a marking function, and dairymen cannot easily distinguish between infected animals and non-infected animals.

  The best mode of the present invention will be described below with reference to the drawings. The best mode described below is merely a part of the present invention, and the present invention is not limited to the best mode.

<Composition of nipple marking sheet for livestock>
First, the nipple marking sheet for livestock according to the best mode is a support body having moderate flexibility, a skin-friendly adhesive layer applied on the support body, and a bonding state with the adhesive layer when not in use. And a release layer that can be easily peeled when used. Furthermore, the adhesive layer is not formed on a part or all of the outer edge of the support, or the adhesive layer is further coated with a coating member (for example, a film) to make it non-adhesive, and the peeling workability is good. The mouth portion is colored in this way. A roll-shaped tape is not suitable because dairymen work with gloves during milking and handling becomes extremely bad.

Hereinafter, the structure of the livestock nipple marking sheet according to the best mode will be described first.
FIG. 1 is a view showing an example of a livestock nipple marking sheet according to the first embodiment. More specifically, FIG. 1A is a diagram showing a state in which the marking sheet 1 is partially isolated from the peeling layer 11 by pinching the chamfered portion 10b of the support 10. FIG. 1B is a surface view of the marking sheet 1. FIG. 1C is a rear view of the marking sheet 1 (after peeling). FIG.1 (d) is a rear view of the said marking sheet 1 (before peeling). FIG. 1E is a cross-sectional view of the marking sheet. The livestock nipple marking sheet 1 according to the figure is in a bonded state with a support 10, an adhesive layer 10a disposed on the support 10, and the adhesive layer when not in use, but easily peeled off when used. Possible release layer 11. Further, a part of the support 10 is not formed with a pressure-sensitive adhesive layer or is coated with a film on the pressure-sensitive adhesive layer so as to be non-tacky (for example, blue) ) Having the chamfered portion 10b. As shown in FIG. 1 b, the colored mouthpiece 10 b is visible through the support 10. Here, for example, as shown in FIG. 1 (e), the chamfered portion 10 b covers the pressure-sensitive adhesive layer 10 a applied to the support 10 with a colored film at one outer edge of the four sides of the support 10. Do it. Hereinafter, each element will be described in detail.

(Structure of support)
The size and shape of the nipple marking sheet (or support) for livestock according to this best mode need to be able to wrap the whole or part of the nipple of the target livestock by deformation (see FIG. 3). Specifically, a square having a side of 5 to 15 cm, preferably 8 to 12 cm (eg, square, rectangle, rhombus), a circle having a diameter of 5 to 15 cm, preferably 8 to 12 cm, or a short axis and a long axis 5-15 cm, preferably 8-12 cm oval. In another form, it is a substantially rectangular shape having a long side of 5 to 15 cm, preferably 8 to 12 cm and a short side of 2 to 6 cm, preferably 2 to 4 cm. Here, “substantially square” and “substantially rectangular” may be such that they can be seen as a substantially rectangular or rectangular shape, and include not only those with corners but also chamfered ones. Further, “substantially circular” and “substantially oval” may be such that they can be seen as substantially circular or oval, and include those that are partially cut. For example, the size and shape of the support sheet 10 shown in FIG. 1B is a substantially square shape with four sides chamfered and one side of about 10 cm. This is a design based on the fact that the sheet is designed for cattle and the nipple thickness of the cattle is approximately 15 to 40 mm.

  Here, the thickness of the support is preferably determined as appropriate depending on the material properties of the support, but is preferably 0.05 to 0.8 mm in consideration of the followability of the skin of the breast. -0.5 mm is more preferable.

(Configuration of adhesive layer)
Next, the pressure-sensitive adhesive layer disposed on the support may be present over the entire surface of the support or may be present only partially. For example, in the support sheet 10 shown in FIG. 1, the adhesive layer 10 a is applied over the entire surface of the support 10 because it is easy to manufacture. However, since livestock may hurt if the nipple is covered with an adhesive, it is a technique that does not provide an adhesive layer for the part that hits the tip of the nipple (for example, pattern coating), or the adhesive of the part It is also effective to cover the layer with a covering member (for example, to leave the release layer in the portion corresponding to the tip of the nipple even after the release layer is peeled off). It is also possible to provide a pad used for a bandage.

(Configuration of the mouthpiece)
Next, the chamfered portion formed at the end of the support does not necessarily have to be present on the livestock nipple marking sheet. However, dairymen need to behave well because they work with gloves such as latex during milking, and because there are many cows that milk twice a day and milk a day, In consideration of further improvement and ease of peeling from the release layer, the presence of the chamfered portion is preferable because rigidity increases and it is easy to grip with the hand of the glove. Here, for example, as described above, the formation method of the chamfered portion may be a method in which the adhesive layer is not formed on the part, or a film or an adhesive film is further coated on the adhesive layer existing in the part. A technique of making it stick may be used. For example, as described above, as shown in FIG. 1 (e), in the livestock nipple marking sheet 1 according to this embodiment, the adhesive layer 10 a is provided over the entire surface of the support 10, and the end of one side is colored. The mouth portion 10b is formed by attaching a film (for example, a blue film). Here, a color with good visibility such as blue, green, red, and yellow is suitable for the color of the mouth portion 10b (color of the colored film when a colored film is attached). In addition, when a colored film is used, as shown in FIG.1 (b), the said coloring can be observed also from the surface through a support body (for example, nonwoven fabric). In addition, since the mouth part is basically not in close contact with the skin, after pasting the nipple marking sheet for livestock on the nipple, the tape part with the mouth part is lightly bent so that it comes into contact with its own nonwoven fabric. It becomes possible to directly recognize the chamfered portion without passing through, and the workability at the time of peeling is improved. The width of the film at the chamfered portion is preferably 1 to 3 cm in consideration of difficulty in peeling during sticking and ease of peeling after sticking for a predetermined time. Moreover, when the material of the film of a mouthpiece part is polyester, 5-80 micrometers is suitable for thickness.

《Materials for livestock nipple marking sheet》
Next, the material of the livestock nipple marking sheet according to the best mode will be described.

(Support material)
The moderately stretchable support constituting the teat marking sheet according to the best mode preferably has flexibility that can follow the expansion and contraction of the skin of the breast and fixation for several hours, and does not cause skin irritation. Is. Here, as for the support body which concerns on this best form, it is suitable that 5% tensile stress (N / 25mm) of MD direction is 2.0-30. This is because if it is less than 2.0, it is too soft to be applied, and if it exceeds 30, it is too hard and does not conform to the skin, making it stiff. In this specification, X% (5%, 10%, 20%) tensile stress and elongation are in accordance with JIS-K7113, using a tensile tester at a temperature of 23 ° C. and an extension rate of 300 mm / min. This is a measurement of stress (sample width 25 mm, gripping interval 50 mm) when the sample is stretched by X% (5%, 10%, 20%). Further, the support according to the best mode has an elongation (%) of preferably 10 to 400, more preferably 20 to 250, and most preferably 20 to 150. If it is less than 20%, it does not fit into the skin, and if it exceeds 250%, it grows too much and is difficult to stick when it is peeled off. Further, the support according to the best mode preferably has a bending hardness (mg · cm) of 50 to 300. In addition, the bending hardness in this specification is measured by performing a test according to the ASTM D1388 Option B heart loop test. Furthermore, since the operation | work which attaches a milking machine requires the judgment of whether milking is quick, the possibility that a transparent support body may equip with a milking machine by mistake and milking will arise. Therefore, a non-transparent support is preferable. In addition, when a support having poor moisture permeability is used, the evaporation of moisture evaporating from the skin is hindered, so that the stratum corneum is adversely affected, such as whitening of the skin and skin irritation caused by skin moistening. For example, even in the case of a urethane film that is considered to have relatively good moisture permeability as compared with a polyolefin or polyester film, in order to improve workability, when the thickness is 50 μm or more, for example, 100 μm, The moisture permeability is low, the adhesiveness at the time of sticking is poor, and there is a problem that the tape does not have a waist when holding the sticking material by hand. In addition, when the film is used, since it is difficult to peel off at the time of peeling, the nipple may be damaged by a nail or the like. Based on the above, the support suitable in the present invention is a woven fabric, a nonwoven fabric or a knitted fabric which is a support having high visibility, moderate flexibility, good moisture permeability, and low risk of damaging the nipple tip. is there. A more preferable support is a nonwoven fabric, a woven fabric, or a knitted fabric using fibers with low stretchability such as polyester fiber, cotton, rayon, polypropylene, polyethylene, cellulose, and the like. A particularly suitable support is a polypropylene spunbonded nonwoven fabric from the viewpoint of touch and workability. Regarding the above-described tensile stress and elongation, the sheet having the adhesive applied to the support has substantially the same numerical value as that of the support (therefore, the preferable tensile stress and elongation of the sheet are the above-described support. Of the same range). On the other hand, the bending hardness (mg · cm) is preferably 15 to 70, more preferably 20 to 65, and most preferably 30 to 60. If it is less than 15, the tape does not have a waist and it is difficult to stick it, and if it exceeds 70, it is too hard and it becomes stiff and the livestock (for example, cattle) hurts during sticking or peeling.

  In addition, you may give the process which provides functions, such as a water repellent function, to a support body. For example, as a method for performing water repellent treatment on a support, a general method such as applying (for example, applying) a water repellent agent to the support, or laminating a film having a water repellent function on the support, etc. The process can be performed by a method. For example, if a polyurethane layer with water repellency and moisture permeability is laminated on one side of the support (the side opposite to the side where the adhesive layer is placed), the support will have a waterproof function as well as a water repellency function. It becomes possible to grant. The urethane used here may be either ether-based or ester-based urethane. Considering moisture permeability, the thickness of the urethane layer is preferably 1 to 40 μm, and more preferably 5 to 30 μm.

(Adhesive material)
As the pressure-sensitive adhesive according to the best mode, rubber-based, acrylic-based, and silicone-based pressure-sensitive adhesives that are pressure-sensitive adhesives generally used for human skin application are preferably used. Here, the rubber-based pressure-sensitive adhesive has an excellent adhesive force to the skin surface, but usually has a high hydrophobicity and poor moisture permeability, so that the skin surface is stuffy due to sweating from the skin surface during application. There is a possibility that the skin adhesive force may rapidly decrease when irritation occurs or when sweating a lot during summer. Therefore, an acrylic adhesive is more suitable. Hereinafter, such an acrylic pressure-sensitive adhesive will be described in detail.

  As the acrylic pressure-sensitive adhesive, a pressure-sensitive adhesive composition containing a carboxylic acid ester in an acrylic copolymer is preferable from the viewpoint of skin irritation. In particular, an acrylic copolymer obtained from a monomer mixture containing (meth) acrylic acid alkyl ester / alkoxy group-containing ethylenically unsaturated monomer / carboxyl group-containing ethylenically unsaturated monomer, and carboxylic acid ester Acrylic pressure-sensitive adhesives containing are preferred. The preferred embodiment will be described in detail below.

  First, an acrylic copolymer obtained from a monomer mixture containing (meth) acrylic acid alkyl ester / alkoxy group-containing ethylenically unsaturated monomer / carboxyl group-containing ethylenically unsaturated monomer will be described. First, as the (meth) acrylic acid alkyl ester which is one monomer component, it is effective to use a long chain alkyl ester having 2 or more alkyl groups and further 6 to 15 carbon atoms, and relatively little irritation to the skin. And, it has an advantage that the adhesiveness is hardly lowered even after long-term use. For example, it is preferable to use isononyl acrylate, 2-ethylhexyl acrylate, or the like. Next, the alkoxy group-containing ethylenically unsaturated monomer that is one monomer is a component that imparts hydrophilicity and moisture absorption to the resulting pressure-sensitive adhesive composition or pressure-sensitive adhesive layer. For example, it is preferable to use an alkoxyalkyl acrylate having an alkoxy group having 1 to 4 carbon atoms, such as methoxyethyl acrylate, ethoxyethyl acrylate, or butoxyethyl acrylate. Next, the carboxyl group-containing ethylenically unsaturated monomer as a monomer has a function of improving the cohesive force of the resulting acrylic copolymer, while ensuring a reactive site for the crosslinking treatment. Examples include acrylic acid and methacrylic acid.

Here, in the production of a copolymer of (meth) acrylic acid alkyl ester / alkoxy group-containing ethylenically unsaturated monomer / carboxyl group-containing ethylenically unsaturated monomer, The alkyl methacrylate is preferably 50 to 90% by weight, more preferably 60 to 80% by weight, and the alkoxy group-containing ethylenically unsaturated monomer is preferably 10 to 60% by weight, and more preferably. Can be produced by blending 20 to 50% by weight of a carboxyl group-containing ethylenically unsaturated monomer in an amount of 0.1 to 8% by weight, more preferably 0.5 to 5% by weight, and copolymerizing them. In addition, as modifying monomers for various modifications such as imparting hydrophilicity, simple monomers such as styrene, vinyl acetate, N-vinyl-2-pyrrolidone, 2-hydroxyethyl acrylate, 2-hydroxypropyl acrylate, etc. The monomer may be appropriately copolymerized as necessary.
The acrylic copolymer preferably has a glass transition temperature of −23 ° C. or lower from the viewpoint of skin adhesive strength. Furthermore, the weight average molecular weight of the acrylic copolymer is adjusted to 1 million or less, preferably about 500,000 to 900,000, so that sufficient skin adhesive force can be exerted even when plasticized by a compatible carboxylic acid ester. It is preferable to do. The polymerization method for obtaining the acrylic copolymer is not particularly limited, such as solution polymerization, emulsion polymerization, suspension polymerization and the like, and is a normal radical such as a peroxide compound or an azo compound. Copolymerization is possible by radical polymerization using a polymerization initiator.

  Next, as carboxylic acid ester, carboxylic acid ester using monohydric alcohol such as ethyl myristate, isopropyl myristate, isopropyl palmitate, butyl stearate, isopropyl isostearate, hexyl laurate, cetyl lactate, myristyl lactate, Carboxylic acid using a dihydric or higher polyhydric alcohol such as propylene glycol dicaprylate, propylene glycol diisostearate, glyceryl tricaprylate, glyceryl tri-2-ethylhexanoate, glyceryl triisostearate, trimethylolpropane tri2-ethylhexanoate It is preferable to use one or more acid esters in combination. Here, the carboxylic acid ester used exhibits liquid or paste-like properties at room temperature.

  The pressure-sensitive adhesive composition preferably contains 10 to 60 parts by weight, particularly preferably 10 to 20 parts by weight, of carboxylic acid ester with respect to 100 parts by weight of the acrylic copolymer.

(Material of other optional components)
In addition, the nipple marking sheet which concerns on this best form may further have the chemical | medical agent which treats the inflammation of a nipple, such as mastitis and nipple inflammation in milking animals, such as a cow. In this case, it is necessary to apply the drug to the part that comes into contact with the inflamed part. For example, a method of introducing the drug into the adhesive layer can be mentioned.

《Method for producing nipple marking sheet for livestock》
The livestock nipple marking sheet according to the present invention can be produced by applying an adhesive to at least one surface of a flexible support according to a conventional method. An adhesive may be applied onto release paper and transferred onto a support. In order to apply the pressure-sensitive adhesive, a solution obtained by uniformly dissolving or dispersing the base polymer and, if necessary, the additive component in an organic solvent may be applied onto a support or release paper and dried. Although the thickness of an adhesive layer is not specifically limited, Usually, it is 15-80 micrometers, Preferably it is about 20-60 micrometers. Then, it cuts suitably and produces a nipple marking sheet for livestock. At that time, it is preferable that the support and the release paper have the same size or are cut so that the release paper is slightly larger than the support.

《How to use livestock nipple marking sheet》
Milking from dairy cows is performed twice a day. During the lactation period, cows with mastitis must be milked for disposal, so it is necessary to distinguish between cows with mastitis and normal cows and staggering the milking time. Since normal milking is generally performed with the butt facing the cow, one or more of the four nipples, preferably the nipples on the butt side, and more preferably the two nipples facing each other. By covering with the sheet, it becomes easy to distinguish from a normal cow that works as a marking. Since the livestock nipple marking sheet is pasted twice a day, it is preferable that the livestock nipple marking sheet can be stuck on the nipple continuously for about 12 hours. For example, in the case of a lactating treatment cow, in the case of a nipple marking sheet for livestock that covers the nipple, nipple cleaning, milking, nipple drying, dipping, nipple drying, and application of a nipple marking sheet for domestic animals In the case of the type of livestock nipple marking sheet to be applied around the nipple, nipple cleaning, milking, nipple drying, pasting of the domestic nipple marking sheet, and dipping are performed in this order. In the case where a livestock marking sheet is pasted around the nipple, the drying operation is reduced, which is more efficient. The dipping is an operation of immersing the tip of the nipple in a chemical for disinfection.

Hereinafter, the usage method (three aspects) of the domestic animal nipple marking sheet which concerns on this best form is explained in full detail.
First, the usage method of the nipple marking sheet for livestock which concerns on a 1st aspect is demonstrated, referring FIGS. 1-4. First, as shown in FIG. 1 (a), just before use, the nipple marking sheet 1 for livestock is peeled from the peeling layer 11 by pinching the mouthpiece 10b. And after putting the said sheet | seat 1 on the whole palm so that the adhesive layer 10a of the nipple marking sheet | seat 1 for domestic animals may become an upper surface, as shown in FIG. 2, the center part of the said sheet | seat 1 is put on the front-end | tip of a domestic nipple. Make contact. Then, by moving the entire palm further upward with the tip of the nipple in contact with the sheet 1, as shown in FIG. 3, the sheet 1 is deformed into a bag shape so that the entire nipple is completely covered. It is covered with a marking sheet 1. As a result of the adhesive layer being provided on all or part of the sheet 1 facing the nipple, the adhesive layer adheres to the nipple and the sheet remains fixed to the nipple. It becomes.

  Next, the usage method of the domestic animal nipple marking sheet which concerns on a 2nd aspect is demonstrated. First, as shown in FIG. 1 (a), just before use, the nipple marking sheet 1 for livestock is peeled from the peeling layer 11 by pinching the mouthpiece 10b. And after putting the said sheet | seat 1 on the whole palm so that the adhesive layer 10a of the said sheet | seat 1 may become an upper surface, in order to position affixing, first, it affixes from the nipple upper part on the head side of a cow, and then the nipple tip The whole palm is moved upward from the part and pasted so as to cover the whole. If it does so, as shown in FIG. 3, the said sheet | seat 1 will deform | transform into a bag shape and the whole nipple will be coat | covered completely. And as a result of the adhesive layer being provided on all or part of the side of the sheet 1 facing the nipple, the adhesive layer adheres to the nipple and the sheet 1 is fixed to the nipple. Will remain.

  Next, the usage method of the nipple marking sheet | seat for livestock when the front-end | tip of a nipple is not covered based on a 3rd aspect is demonstrated. First, as shown in FIG. 17, the nipple marking sheet 1 for livestock is peeled from the peeling layer 11 by pinching the mouthpiece 10b immediately before use. And as shown in FIG. 18, it sticks so that the adhesive layer 10a of the said sheet | seat 1 may wind up so that the front-end | tip part of a nipple may be removed and may be fixed, and it sticks so that a mouthpiece part can be visually recognized. Fig. 18 (a) is a side view of an aspect in which a nipple marking sheet for livestock is affixed to a cow's nipple, and the palm is pasted, and Fig. 18 (b) is a cross-sectional view taken along line AA in Fig. 18 (a). It is. At this time, as shown in FIG. 18, it is preferable to use a palm-to-paste method to bond the adhesive surfaces together because it is difficult to peel off in use, but as shown in FIG. 19, the adhesive is overlapped on the support of the patch itself. It may be affixed. FIG. 19A is a side view, and FIG. 19B is a cross-sectional view taken along line BB in FIG. 19A. In this example, since the livestock nipple marking sheet 1 is made of a non-woven fabric, the colored mouth portion 10 b is visible from the opposite side of the sheet 1.

  FIG. 20 is a livestock nipple marking sheet according to the third embodiment. Here, FIG. 20 is a rear view of the livestock nipple marking sheet according to the third embodiment. Here, FIGS. 20 (a), (b), (c) and (d) are respectively a plan view, a front view, a rear view and a right side view of the livestock nipple marking sheet according to the embodiment (all peeled). Before). As shown in FIG. 20 (b), the configuration except for the shape that is substantially rectangular and that completely covers the chamfered portion 10b opposite to the peeling layer 11 and extends outward is the nipple for domestic animals according to the first embodiment. Same as marking sheet. In this embodiment, the release layer 11 is formed in a size larger than the support in both the longitudinal direction and the transverse direction. With this configuration, the mouthpiece 10b can be easily pinched and easily peeled from the release layer 11 even when wearing gloves. Moreover, since the shape is substantially rectangular, it is possible to suitably remove the tip of the nipple and wind it so that it is fixed to the periphery, and attach it so that the mouth portion is visible.

  In the first aspect to the third aspect, it is preferable that the mouth portion is disposed in the nipple portion on the tail side (that is, the side opposite to the head) of the cow after the pasting. The reason is as follows. As mentioned earlier, milk must be milked for disposal from cows with mastitis during lactation. Therefore, it is necessary to peel off the marking sheet affixed to the nipple of a cow with mastitis. At this time, the milking operation is performed from the tail side of the cow. Therefore, when the chamfer is arranged in the direction of the tail of the cow, the peeling work from the tail side of the cow becomes easy, and the peeling work and the milking work can be performed continuously. In particular, as described above, dairymen need to behave neatly because they work with gloves such as latex at the time of milking, and because there are many cows that are milked twice a day and milked a day. Among them, the merit of using the sticking mode is great.

《Example shape of livestock nipple marking sheet》
