Description

[Technical Field]

[0001] The present invention provides Dog toothbrush It is related to. [Background technology]

[0002] Pet dog owners manage their pets' health by controlling the quality and quantity of food they give them according to their pets' appetites to prevent them from becoming obese.

[0003] In particular, the number of owners who start brushing their dogs' teeth after they are a few months old is increasing year by year. In this case, owners need to purchase commercially available pet toothbrushes in the appropriate sizes for various dog breeds from pet shops or online stores.

[0004] Here, Patent Document 1 below discloses a pet toothbrush that functions both as a toothbrush and a plaque remover.

[0005] Furthermore, toothbrushes of various shapes have been put into practical use for humans as well as pets (Patent Document 2).

[0006] By the way, if you look around at some media outlets on the Internet, you will find the following comments published about dog tooth brushing habits: "It has been reported that over 90% of dog owners feel that their dogs need dental care at home. For example, care that uses snacks that also serve as teeth brushing, care that uses toothbrushes, care that uses toothpaste sheets, gloves, and gauze, care that uses finger brushes, and care that uses supplements. These comments suggest that care using snacks that also double as tooth brushing accounts for approximately half of the cases, care using toothbrushes, toothpaste sheets, gloves, and gauze accounts for approximately 30%, and care using finger brushes accounts for approximately 10%.

[0007] According to these statistics, more than 90% of owners feel that their pet dogs need dental care at home, and many owners combine multiple types of dental care. [Prior art documents] [Patent documents]

[0008] [Patent Document 1] Japanese Patent Application Laid-Open No. 2012-231968 [Patent Document 2] Japanese Patent Application Laid-Open No. 2008-302164

[0009] The teeth on a dog's lower and upper jaws differ from those of humans, with the upper jaw having a tooth row that is narrow at the tip and spreads out to the back teeth, with the longest canine tooth as the base and curving from the inside to the outside, while the upper jaw has a tooth row that spreads out smoothly from the longest canine tooth to the fifth tooth, with the tooth row curving slightly inward from the fifth tooth to the back teeth. Summary of the Invention [Problem to be solved by the invention]

[0010] In order to brush each of the canine teeth, which are arranged in a characteristic shape, owners often give their dogs treats and brush them repeatedly, but they often end up leaving some teeth unbrushed.

[0011] On the other hand, owners would like to be able to brush all of their canine teeth thoroughly with one toothbrush, but commercially available toothbrushes do not meet this requirement.

[0012] Dog owners also recognize that tooth brushing is an important habit, but apart from some who have gotten used to brushing their dog's teeth to the point that they prefer it, most dog owners often use tools other than toothbrushes, although this depends on the breed and the owner's habits.

[0013] On the other hand, some dog owners say that if they use an appropriately shaped toothbrush and can eliminate discomfort, the habit of brushing their dog's teeth will become established, and that continuing the habit of brushing their dog's teeth can contribute to maintaining their dog's long-term health.

[0014] Furthermore, the path of toothbrushing for dogs shown in videos and other media is often so linear that the brushing path is so far removed from the way the toothbrush touches the gums that most pet dogs turn their heads away just by looking at the toothbrush.

[0015] In particular, commercially available toothbrushes have bristles planted so that the top is flat.

[0016] However, when actually brushing the teeth, it is difficult to apply the brush perpendicularly to the outer surface of the teeth because the teeth are covered by the skin of the face, and even if it were possible, it would be difficult to brush all of the pet's teeth thoroughly without leaving any areas unbrushed unless the owner carefully selected the angle of their arm or wrist.

[0017] Similarly, when brushing the inside of your dog's teeth, even if you open the mouth and move the teeth up and down, it does not open 180 degrees like a tooth model, so with a flat toothbrush surface, the contact of the brush tip with each tooth is uneven, making it difficult to brush thoroughly without leaving any teeth unbrushed.

[0018] Moreover, according to the above statistics, owners tend to take the easy way out and focus on using dental gum as the main method of dental care for their pet dogs, and use other dental care methods as a supplement.

[0019] Specifically, because a dog's mouth cannot be opened 180 degrees, the toothbrush must be applied at an angle to some extent, and if the brush has flat bristles, in order to increase contact with the tooth surface, the top of the brush must be pressed forcefully against the tooth surface, resulting in the corners of the flat surface hitting the gums and gingiva in the mouth too hard. As a result, the dog will start to dislike toothbrushing itself, making toothbrushing itself difficult for the owner.

[0020] As such, many owners recognize the importance of brushing their dog's teeth, but they make it seem like they've done so by using easy dental care such as chewing gum.

[0021] However, in reality, dental care using gum alone is not believed to be sufficient to maintain the oral health of pet dogs, and brushing the teeth by owners, which is highly effective dental care, is time-consuming and there is a fear that it may damage the oral cavity of pet dogs. As a result, the adoption rate is low and the oral hygiene environment for pet dogs has not yet been established.

[0022] In light of the above findings, the applicant has repeatedly tried and tested the shape of the brush attached to the base of a conventional dog toothbrush in order to promote the habit of brushing the teeth of pet dogs, and has developed a toothbrush that can contribute to the oral hygiene environment of dogs for both pet dogs and their owners. Dog toothbrush This provides:

[0023] The present invention has been made to solve the above-mentioned problems, and the object of the present invention is to provide a brush with a mountain-shaped tip that can be adapted to fit the arrangement of canine teeth arranged on the upper and lower jaws of dogs, while minimizing contact with the corners to minimize pain and discomfort, allowing for stress-free, comprehensive brushing of the entire tooth with ease. Dog toothbrush The purpose is to provide [Means for solving the problem]

[0024] To achieve the above object, the dog toothbrush of the present invention has the following configuration. A dog toothbrush for brushing the dentition in a dog's mouth, comprising a head portion on which tufts of bristles are implanted, a neck portion extending from the head, and a handle portion extending from the neck portion, which are integrally formed; the tufts of bristles have a first mountain shape that descends with a predetermined curvature toward the upper end and the lower end from an apex at the center position in the vertical direction of the head portion, and a second mountain shape that descends at an acute angle toward the left end and the right end from an apex at the center position in the vertical direction of the head portion; and the lengths of adjacent bristles on the head portion are randomized with respect to the first mountain shape and the second mountain shape. The hair bundle includes hairs planted in an oblique direction so as to be inclined toward the top. It is characterized by: [Effects of the Invention]

[0025] According to the present invention, the mountain-shaped brush tip adapts to and fits the arrangement of the canine teeth located on the upper and lower jaws of a dog, allowing for stress-free, comprehensive brushing of the entire tooth with ease and operability.

DETAILED DESCRIPTION OF THE INVENTION

[0027] Next, the best mode for carrying out the present invention will be described with reference to the drawings. The following embodiments relate to a dog toothbrush and include essential features of the invention as well as alternative and preferred embodiments.

[0028] <System configuration description> [First embodiment] FIG. 1 is a plan view illustrating the alignment of a dog's teeth to which the present invention is applied. In Figure 1, 1 shows the tooth arrangement in the upper jaw, and the number of permanent teeth in an adult dog is 20 in the upper jaw: incisors (6) + canines (2) + premolars (8) + molars (4). 22 in the lower jaw: incisors (6) + canines (2) + premolars (8) + molars (6). This means that a total of 42 teeth usually grow out of the gums.

[0029] Furthermore, the shape of the dentition of an adult dog is characterized by complex curvature.

[0030] 2 is a side cross-sectional view showing the configuration of a dog toothbrush according to this embodiment. This embodiment is a dog toothbrush for brushing the dentition in a dog's mouth, and has a structure in which a head portion in which tufts of bristles are implanted, a neck portion extending from the head portion, and a handle portion extending from the neck portion are integrally formed.

[0031] Figure 2(a) shows the first toothbrush, and Figure 2(b) shows the second toothbrush. The bristles of the first toothbrush are planted so that the mountain shape follows a gentler curve than the second toothbrush. The bristles can be made of artificial bristles (nylon, polyester, etc.) or natural bristles (hog bristles, horse bristles, etc.). The bristles may be planted with a uniform thickness, or with uneven thickness, with the bristles being thin at the top of the mountain shape and thicker towards the base.

[0032] This reduces the fit of the tip that comes into contact with the dog's gums, and prevents the arched shape from being damaged even if the number of times the toothbrush is used increases due to tooth brushing habits.

[0033] FIG. 3 is a diagram illustrating the different brushing methods using the first toothbrush and the second toothbrush shown in FIG. 2, and the tooth row is the same as the tooth row shown in FIG.

[0034] In FIG. 3, 21 denotes the head of the first toothbrush, and 22 denotes the head of the second toothbrush.

[0035] The owner communicates with their dog and, in a relaxed state, calls out to their dog and tells them what action to take next.

[0036] The dog toothbrush shown in this embodiment is for brushing the curved rows of teeth that grow inside a dog's mouth, and is integrally formed with a head portion on which tufts of bristles are implanted, a neck portion extending from the head portion, and a handle portion extending from the neck portion.

[0037] The dog toothbrush has a first tuft shape with a curve that curves upward and downward from the vertical center of the head, descending with the curvature of the curve formed by the row of teeth that grows along the shape of the dog's jaw, and a second tuft shape with a curve that curves downward at an acute angle from the vertical center of the head toward the left and right ends, and the bristles are planted on the first tuft shape and the second tuft shape so that the lengths of adjacent bristles on the head are random. Here, "random" means that the lengths of the tips of the long and short bristles are irregular (uneven), for example, within a range of 3.1 mm to 4.1 mm, but the difference in tip length is not limited to this.

[0038] The hair implantation pattern on the head portion may be an arrangement of equal-spaced vertical or horizontal rows, or may be an arrangement in which the hair implantation pattern itself is random.

[0039] More specifically, the brush comprises a first head portion 21 and a second head portion 22, a neck portion, and a handle portion, which are configured as hair implantation portions in which tufts of hair are implanted from the tip a to the rear end b of the head portions 21 and 22, so that the tufts of hair are implanted in a shape that approximates part of the curve formed by the row of teeth that grows along the shape of a dog's jaw (see Figure 1) from the outside of the row of teeth, and the tufts of hair are implanted in a slightly pointed mountain shape (see Figure 4) on both sides based on the center of the tuft of hair from the tip a to the rear end b, and the lengths of the individual hairs that make up the tufts are uneven.

[0040] In particular, the first head portion 21 and the second head portion 22 onto which the hair is implanted have hair bundles implanted from the tip a to the rear end b of the implanted head portions 21, 22 in a shape that approaches from the outside of the tooth row part of the curve with different curvatures formed by the row of teeth that grows along the shape of the dog's jaw, and the hair bundles are implanted in a slightly pointed mountain shape on both sides based on the center of the hair bundle from the tip to the rear end, and the length of each hair that makes up the hair bundle is implanted randomly (unevenly).

[0041] In this example, the radius of curvature of the first head portion 21 shown in FIG. 2(a) is slightly larger than the radius of curvature of the second head portion 22 shown in FIG. 2(b).

[0042] Here, the radius of curvature of the first head portion 21 shown in Figure 2(a) and the radius of curvature of the second head portion 22 shown in Figure 2(b) are varied to provide characteristic sizes for each breed of dog, small, medium, and large dogs, making it possible to provide a toothbrush that is suitable for any breed of dog, small, medium, or large dog.

[0043] [Upper jaw brushing] First, the owner inserts the index finger of their left hand between canine tooth T1 or canine tooth T2 and adjusts the upper and lower jaws to open. Next, the owner gently brushes the teeth 22-1 to 22-5 shown in Figure 3 by lightly contacting the head part 22 with the gums at an angle of about 45 degrees to the teeth. After brushing the teeth 22-1 to 22-5 shown in Figure 3, the owner should give the dog a small treat and praise the dog for brushing its teeth.

[0044] Next, gently brush the teeth 21-1 and 21-2 shown in Figure 3 by lightly contacting the head 21 with the gums at an angle of about 45 degrees to the teeth. Once brushing of the teeth 21-1 and 21-2 shown in Figure 3 is complete, give your dog a small treat and praise it for brushing its teeth.

[0045] [Brushing the lower jaw] First, the owner inserts the index finger of their left hand between canine tooth T3 or canine tooth T4 and adjusts the upper jaw so that it opens. Next, the owner gently brushes the area between teeth 22-6 to 22-12 shown in Figure 3 by lightly pressing head 22 against the area, for example, with the angle between the gums and the teeth at about 45 degrees. After brushing teeth 22-6 to 22-12 shown in Figure 3, the owner should give the dog a small treat and praise the dog for brushing its teeth.

[0046] Next, gently brush the teeth 21-3 and 21-4 shown in Figure 3 by lightly contacting the head 21 with the gums at an angle of about 45 degrees to the teeth. Once brushing of the teeth 21-3 and 21-4 shown in Figure 3 is complete, give your dog a small treat and praise it for brushing its teeth.

[0047] FIG. 4 is a cross-sectional view showing the state of hair implantation in the head portions 21 and 22 shown in FIG. (a) shows the cross-sectional shape of the toothbrush in the short direction, (b) shows the cross-sectional shape of the toothbrush in the long direction, and (c) shows the length of the bristles that make up the brush.

[0048] The toothbrush shown in this embodiment has a mountain-shaped top, bottom, side and both surfaces.

[0049] As shown in Figure 4, the shape of heads 41, 42, and 43 is such that the bristles are not planted to form a flat surface like conventional toothbrushes, but are planted in a mountain shape with a convex portion at the top. Note that the material of the base may be made of an elastic material, such as rubber or soft plastic, if it has the structure shown in Figure 6, which will be described later.

[0050] In this embodiment, as shown in Figure 4(c), the length of each bristles of the brush is random and short, and the bristles are planted as densely as possible. The bristles are made of a soft material, and are designed to be able to wrap around and contact each tooth.

[0051] This allows food debris and the like to be efficiently scraped away and plaque to be removed when brushing.

[0052] Furthermore, when the toothbrush moves around inside a dog's mouth during brushing, it often hits the flesh of the cheek, causing discomfort.

[0053] In contrast, the shape of the toothbrush shown in this embodiment allows for a comfortable contact between the toothbrush and the teeth, ensuring stress-free, comprehensive contact with the teeth. This makes it easier for your pet dog to brush its teeth better and develop the habit of doing so.

[0054] [Effects of the first embodiment] According to this embodiment, the brush tip has a mountain-shaped tip, with the bristles being randomly planted and forming sharp edges, which can adapt to and fit the arrangement of the canine teeth on the upper and lower jaws of a dog, while minimizing contact with the corners to reduce pain and discomfort, allowing for easy and stress-free brushing of the entire tooth area.

[0055] Second Embodiment FIG. 5 is a perspective view showing the structure of the dog toothbrush according to this embodiment.

[0056] In FIG. 5, reference numeral 51 denotes a toothbrush, which is composed of a main body 52 and a brush part 53 that are detachable in the vertical direction.

[0057] Reference numeral 54 denotes an elastic portion, which allows the tip of the toothbrush to be bent or raised up and down, for example, starting from the second joint of the index finger.

[0058] This allows the tip of the toothbrush to contact the teeth at an angle of, for example, 45 degrees inside your dog's mouth, allowing you to scrape away plaque.

[0059] This means there is no need to purchase two toothbrushes in advance; simply by replacing the brush head, one brush body can be used to brush all sizes of dogs, including small, medium and large.

[0060] [Effects of the second embodiment] According to this embodiment, brush sections suitable for small, medium and large dogs can be attached and detached to one toothbrush body, so that even if the dog grows or the size of its jaw changes, you can use the Blythe section of the appropriate size to brush your dog's teeth, making it highly economical.

[0061] Third Embodiment FIG. 6 is a perspective view showing the structure of the dog toothbrush according to this embodiment.

[0062] In Figure 6, 61 is a ring portion that is molded integrally with the head portion and is configured so that the index finger or middle finger of the owner's dominant hand can be inserted therethrough. As shown in Figure 5, the head portion of the dog toothbrush shown in this embodiment is configured to be detachable from the main body portion, so that the owner inserts their index finger or middle finger into the ring portion of the head portion when brushing. This allows the toothbrush, which becomes part of the fingertip, to be manipulated inside the dog's mouth.

[0063] This allows the toothbrush's straightness to allow the tip to move freely around your dog's mouth, allowing you to thoroughly brush even those teeth that are often left unbrushed (especially around the front teeth, with canines being a good example).

[0064] In addition, because the owner's fingers are used directly, for dogs with a sensitive sense of smell, creating an oral environment with a strong, familiar smell of the owner's fingertips can also help alleviate the dog's aversion to having its mouth brushed.

[0065] [Effects of the third embodiment] According to this embodiment, the tip of the toothbrush shown in the second embodiment can be used to cleanly and carefully scrape away plaque from around the front teeth in your dog's oral cavity, preventing poor health caused by periodontal disease.

[0066] [Fourth embodiment] In the first to third embodiments, the configuration of one dog toothbrush has been described, but in order to adapt to the different jaw curvature shapes described above, the dog toothbrushes shown in Figures 2(a) and 2(b) may also be configured as a set of dog toothbrush systems.

[0067] Specifically, the dog toothbrush system comprises a first dog toothbrush and a second dog toothbrush for brushing the curved row of teeth that grow inside a dog's mouth. The first dog toothbrush (head portion 21) comprises a first head portion 21 and a second head portion 22 that form a first bristle-implanted portion in which tufts of bristles are planted from the tip to the rear end of the base on which the bristles are planted, in a shape that approaches part of the first curve C1 formed by the row of teeth that grows along the shape of the dog's jaw from the outside of the row of teeth, and in which tufts of bristles are planted in a slightly pointed mountain shape on both sides based on the center of the tufts from the tip a to the rear end b, and the lengths of the bristles that make up the tufts are uneven, as well as a neck portion and a handle portion that are integral with these.

[0068] The second dog toothbrush (head portion 22) comprises a second bristle implantation portion and second head portion 22, in which bristles are implanted from the tip to the rear end of the base on which the bristles are implanted in a shape that approaches part of a second curve C2 formed by the row of teeth that grows along the shape of the dog's jaw from the outside of the row of teeth, and in which the bristles are implanted in a slightly pointed mountain shape on both sides based on the center of the bristles from the tip a to the rear end b, and in which the lengths of the bristles that make up the bristles are uneven, as well as a neck portion and a handle portion that are integral with these.

[0069] The first curve C1 and the second curve C2 have different radii of curvature.

[0070] [Effects of the fourth embodiment] According to this embodiment, by purchasing the first head unit 21 and the second head unit 22 separately or by purchasing a system in which they are sold together, it is possible to brush every corner of the entire dentition in the dog's oral cavity with a consistent fit, even though the dentition grows in a curved shape inside the dog's oral cavity, thereby improving measures against periodontal disease in dogs and even extending the dog's lifespan.

[0071] Fifth Embodiment The hair bundles on the head shown in Figure 4 are planted in a direction perpendicular to the plane, but when planting odd-numbered hairs in a vertical row, they may be planted at an angle so that they fall toward the top. of In the direction Hair transplant A configuration in which

[0072] [Effects of the fifth embodiment] According to this embodiment, it is possible to prevent the shape of the bristles on the top side from becoming distorted depending on the state of use of the toothbrush.

[0073] Although the above embodiments do not mention the quality of the bristles to be implanted, in terms of the category of commercially available toothbrushes, they belong to the soft category, and animal hair or artificial bristles are used.

[0074] Sixth Embodiment 7 is a diagram showing the structure of the dog toothbrush according to this embodiment, which shows the state of bristles planted in the head portions 21 and 22 shown in FIG.

[0075] (a) shows the cross-sectional shape of the toothbrush in the short direction, (b) shows the cross-sectional shape of the toothbrush in the long direction, and (c) shows the length of the bristles that make up the brush.

[0076] The toothbrush shown in this embodiment has a mountain-shaped top and bottom, side and both sides. Unlike the tapered bristles shown in Figure 4, the top surface of the bristles has a gently sloping mountain-shaped structure.

[0077] As shown in Figures 7(a) to 7(c), the heads 71, 72, and 73 are not shaped to form a flat surface like conventional toothbrushes, and instead the dog toothbrush shown in this embodiment has bristles planted in a mountain-like shape in the vertical direction that is convex toward the top, and a horizontal shape in which the length of the bristles gradually decreases from the center toward the outside. Note that the material of the base may be made of an elastic material, such as rubber or soft plastic, if it has the structure shown in Figure 6, which will be described later.

[0078] In this embodiment, as shown in Figure 7(c), the length of each bristles of the brush is random and short, and the bristles are planted as densely as possible. The bristles are made of a soft material so that they can wrap around and contact each tooth.

[0079] This allows food debris and the like to be efficiently scraped away and plaque to be removed when brushing.

[0080] Furthermore, when the toothbrush moves around inside a dog's mouth during brushing, it often hits the flesh of the cheek, causing discomfort.

[0081] The toothbrush for dogs shown in FIG. 7 may also be configured so that the tip is detachable.

[0082] Furthermore, the tip of the dog toothbrush shown in Figure 4 and the tip of the dog toothbrush shown in Figure 7 may be formed as a pair on the same handle, allowing the owner to use the two types of toothbrushes by switching between them as needed to brush the canine teeth according to their dentition.

[0083] [Effects of the Sixth Embodiment] According to this embodiment, it is possible to efficiently complete tooth brushing for dogs with different tooth structures, from small dogs to large dogs, while observing the dog's reaction when brushing.

[0084] In addition, it is possible to reliably remove plaque that forms depending on the smell of the food eaten by the dog, particularly the menu (food (hard or soft)).

[0085] This means that owners can contribute significantly to their dogs' longer lifespans by helping them develop proper tooth brushing habits.

[0086] The present invention is not limited to the above-described embodiments, and various modifications (including organic combinations of the respective embodiments) are possible based on the spirit of the present invention, and these are not excluded from the scope of the present invention.

[0087] In this embodiment, a toothbrush for dogs has been described, but by changing the size of the toothbrush, it can also be applied to other animals, such as cats, cows, pigs, giant pandas, deer, etc.
