Detailed description of the invention
An embodiment of toothbrush of the present invention is described.
Fig. 1 represents the side view of the toothbrush of present embodiment.The toothbrush 1 of present embodiment has: planting hair has the brushhead 10 of pieces 11 and be extended the handle portion 20 of the strip being arranged on brushhead 10.
In toothbrush 1, brushhead 10 and handle portion 20 one-body molded be as a whole strip, such as resin can be obtained as material by ejection formation.
Described resin can consider the decision such as rigidity, mechanical property that toothbrush 1 requires.Such as, by the high hardness resin using crooked elastic rate (JISK7203) to be in 500 ~ 3000MPa scope, the mechanical property that toothbrush 1 needs can be obtained.As such high hardness resin, list such as polypropylene (PP), PET (PET), polycaprolactam (PCT), polystyrene (PS), acrylonitrile-butadiene-styrene copolymer (ABS), cellulose propionate (CP), polyarylate, Merlon and acrylonitrile-styrene (AS)---etc.In these a kind or multiple can be used.
In addition, in handle portion 20, in order to improve holding, also can be such as partly or integrally cover the soft resin such as elastomer.
As shown in Figure 2, plant territory, hair-fields 12 in brushhead 10, tie up the pieces 11 of multiple bristle by implanting planting in pore 13 in lattice arrangement.
At this, planting territory, hair-fields 12 is regions that the imaginary line A obtained by the outermost outermost portion of respectively planting the peritreme of pore 13 of connection is surrounded as.This imaginary line A forms the adjacent tangent line of planting between pore 13.
Plant territory, hair-fields 12 to have: a mao portion 12b is planted in the front portion of to plant mao portion 12a to the pieces interval that tip side is configured from the base end side of brushhead 10 and being configured to plant than pieces interval the close tip side of mao portion 12a.
At this, it is adjacent pieces 11 is configured by interval each other from part from the cardinal extremity across brushhead 10 to the center line B planting territory, hair-fields 12 on top (in fig. 2, indicate be configured to each other with the example of length L3 across interval across the adjacent pieces 11 in center line B ground) that mao portion 12a is planted at pieces interval.Namely, pieces interval is planted a mao portion 12a and is referred to, the top of the following buffer part 12c on the direction from cardinal extremity to top of brushhead 10, when the line will intersected vertically with the center line B planting territory, hair-fields 12 is as imaginary line C, the region of the base end side of the brushhead 10 that lower layer line C and imaginary line A surrounds.
Plant at such pieces interval in mao portion 12a, planting the part 12c (following, sometimes also referred to as " buffer part 12c ") being formed with near the center line B in territory, hair-fields 12 and not planting mao mao's bundle.Therefore, planting in territory, hair-fields 12, the region existing for pieces 11 to base end side opening, from directly over the shape seen in such as roughly U-shaped.
In addition, the region that mao portion 12b refers to the tip side of the brushhead 10 that imaginary line C and imaginary line A surrounds is planted in front portion.
At this, the cardinal extremity of brushhead 10 refers to the outermost portion of planting pore 13 being positioned at handle portion 20 side in brushhead 10.
The buffer part 12c of present embodiment is rectangular-shaped with what be length direction from the cardinal extremity of brushhead 10 towards the direction on top.When the length direction of rectangular-shaped buffer part 12c is the direction from the cardinal extremity of brushhead 10 towards top, then can guarantee that pieces 11 enters neck portion fully.
Described buffer part 12c is positioned at the central authorities of the width of planting territory, hair-fields 12.When buffer part 12c is positioned at the side side of planting territory, hair-fields 12, the entering of bristle tips to neck portion of pieces 11 cannot be played.
Pieces interval plant mao portion 12a from the cardinal extremity of brushhead 10 towards the length L1 on the direction on top be direction from the cardinal extremity of brushhead 10 towards top plant 25 ~ 75% of the length L2 in territory, hair-fields 12, be preferably 30 ~ 70%, be more preferably 50 ~ 60%.Specifically, described L1 be at the cardinal extremity from brushhead 10 towards in the direction on top, plant the base end side of the brushhead 10 in territory, hair-fields 12 and front portion plant mao base end side of portion 12b the base end side of planting pore 13 between distance.In addition, specifically, described L2 be at the cardinal extremity from brushhead 10 towards in the direction on top, plant the base end side of the brushhead 10 in territory, hair-fields 12 and front portion plant the top side of mao portion 12b the top side of planting pore 13 between distance.
During described lower limit that described L1 is not enough, pieces interval is planted mao bristle tips of the pieces of portion 12a 11 and is declined to the entering in neck portion.
The cardinal extremity from brushhead 10 of described L1 i.e. buffer part 12c is towards the length the direction on top.
Therefore, when meaning that L1 exceedes described higher limit, buffer part 12c is also formed in the tip side of planting territory, hair-fields 12.Usually, in order to make to apply stronger pressure when cleaning molar or the flank of tooth to the pieces 11 of tip side, when the tip side formation of planting territory, hair-fields 12 does not have the buffer part 12c of pieces 11, to the sparse sense of bristle producing pieces 11 deficiency when molar or flank of tooth cleaning, infringement use sense.
Pieces interval is planted in mao portion 12a, and across center line B ground, adjacent pieces 11 standoff distance L3 is each other, and 15 ~ 70% of length L4 on the direction that intersects vertically of the center line B planting territory, hair-fields 12, be preferably 20 ~ 50%, be more preferably 25 ~ 30%.Specifically, described L3 is the distance between inner side of planting pore 13 of planting mao portion 12a across the adjacent pieces interval, center line B ground of planting territory, hair-fields 12.In addition, specifically, described L4 is in the direction vertical with center line B, is planting the outermost of planting pore 13 of side side of a side in territory, hair-fields 12 and the distance between the outermost of planting pore 13 of the side side of the opposing party.
During described lower limit that described L3 is not enough, bristle tips declines to the entering in neck portion, and when described L3 exceedes described lower limit, the brushing of tartar declines.
The size being provided with the brushhead 10 of planting territory, hair-fields 12 can be considered to decide in intraoral operability etc., and such as width makes 10 ~ 15mm, and thickness makes 4 ~ 8mm.
As forming the bristle of pieces 11, can enumerate reduce gradually to its diameter of bristle tips bristle (taper hair), bristle other parts except whole round portion be formed as the roughly the same bristle of external diameter (broad wool) etc.Plant at pieces interval in mao portion 12a, because the entering of bristle tips to neck portion uprises, can more effectively prevention of periodontal disease, thus bristle be preferably taper hair at least partially, more preferably bristle is all taper hair.
As taper hair, can enumerate such as, two ends be processed into taper taper hair, only have one end to be processed into the taper hair of taper, on 1 hair, to be formed with the taper hair etc. in multiple sharp-pointed portion.
In addition, bristle also can be mixing taper hair and broad wool.Such as, also pieces interval can be planted a mao bristle of portion 12a and do tapered hair, front portion be planted a mao bristle of portion 12b and make broad wool.In addition, plant in mao portion 12a at pieces interval, also can mix taper hair and broad wool.
The material of bristle can use such as, the polyamide such as 6-12 nylon, 6-10 nylon; The polyester such as PET, polybutylene terephthalate (PBT) (PBT), PTT (PTT), PEN (PEN), PBN (PBN); The polyolefin such as PP; And the synthetic resin material of the elastomer such as polyolefin elastomer, ethene based elastomers etc.
Multiple combinationally using can be selected in these resin materials, wherein, from the viewpoint that can easily strengthen elasticity, make the brushing of tartar become larger, the mixture of preferred multiple polyester, the preferably mixture of 2 ~ 3 kinds of polyester.
As the mixture of multiple polyester, the mixture of the PET such as preferably listed and polybutylene terephthalate (PBT) (PBT).In addition, bristle also preferably has the polyester bristle of the multiple cored structure in the sheath portion of more than at least 1 layer in the outside comprising core and be arranged on described core.When there is multiple cored structure, because core and sheath portion can use different polyester, so the adjustment of mechanical performance becomes easy.Therefore, it is possible to easily obtain comparatively strong, higher to the brushing of the tartar bristle of elasticity.As the combination of the different polyester that can be used on the bristle in described core and sheath portion, such as preferred polybutylene terephthalate (PBT) (PBT) and PET.
The shape of cross section of bristle is preferably circular, but is not necessarily be defined in circle, can be arbitrary shape according to the object purposes of toothbrush 1.Such as, can be that oval, polygon (such as, can enumerate triangle, quadrangle, pentagon, hexagon etc.), abnormity (star, cloverleaf pattern, bunge bedstraw herb shape etc. such as, can be enumerated.) etc. shape.
When cross section is circular, from making elasticity grow, making to change high viewpoint to the brushing effect of tartar, the thickness (namely, maximum gauge) of bristle is preferably more than 6mil, below 10mil.
But, as bristle, when using the bristle with multiple cored structure or the bristle be made up of polyester mixture to make elasticity strengthen, even if the thickness of bristle also can obtain higher brushing effect less than 6mil.
In addition, sweep the considerations such as sense, cleaning effect, durability from use sense, brush, also bristles different for thickness at random can be combinationally used.
The staple length of bristle is preferably, when adult uses from brushhead 10 plant hair side for 8mm ~ 13mm, when children use from planting hair side of brushhead 10 be 6mm ~ 9mm.The length of bristle can be all identical, also can be not identical.As the pieces that the length of bristle is not identical, list so a kind of pieces: the central uplift length of each bristle being chosen to make pieces.
In addition, do not need to make whole bristles be bristle of the same race.Such as, planted hair to plant mao pieces of portion 12a 11 at pieces interval to plant mao pieces of portion 12b 11 in front portion also can be not identical with being planted hair.The main effect of planting mao pieces of portion 12a 11 due to pieces interval is the tartar removing neck portion, and the part beyond neck portion is cleaned in the main effect that mao pieces of portion 12b 11 is planted in front portion, thus preferably uses the bristle adapted with effect.
As the fur planting method of pieces 11, flat wire can be suitable for and throw the well-known method such as method, hot fusing method into.
Throwing in method at flat wire, is two by many bristles are pricked Shu Houyi folding, throws into and plant pore after clamping is called as the anti-falling piece of flat wire in-between, thus pieces 11 is planted hair and respectively planting pore 13.
Flat wire is by planting the central part of pore 13 and squeezing into be arranged on plant in pore 13 across planting pore 13 ground.As the material of flat wire, such as, can enumerate the metal such as brass, stainless steel, other rigid plastics, biodegradable plastics etc. can also be enumerated.
Although the length of flat wire, width, thickness can corresponding pieces 11 or plant pore 13 and at random adjust, usually, the length of flat wire is larger than the diameter of planting pore 13, and the width of flat wire is less than the degree of depth of planting pore 13.In addition, by regulating the thickness of flat wire, pieces 11 reliably can be fixed on and plant in pore 13 and reduce space.In addition, in order to prevent flat wire from deviating from from planting pore 13, the length of the part preferably exposed from the both sides of planting pore 13 adds up to 0.3 ~ 0.6mm.
Pieces 11 plant hair the shape of planting pore 13 be not particularly limited, can enumerate such as, circular, oval, tetragonal etc.
As long as the thickness of pieces 11 can be made the aperture enabling its bristle tips enter neck portion by part or all the diameter of planting pore 13, not by not restriction, be preferably 1.0 ~ 1.3mm.
Plant the diameter of pore 13 when more than 1.0mm, even if the hair of planting throwing method into by flat wire is also easy to pitch of holes to do narrow, be difficult to feel the sparse sense of bristle.On the one hand, as long as the diameter of planting pore 13 is at below 1.3mm, the entering to neck portion just can be made to become higher.In addition, when the diameter of planting pore 13 diminishes, the free degree of planting pore configuration improves.
Especially, the diameter of planting pore 13 that mao portion 12a is planted at pieces interval is preferably 1.0 ~ 1.3mm.Mao pieces of portion 12a 11 is planted using entering as main object to neck portion in pieces interval.Therefore, planting by making pieces interval the diameter of planting pore 13 that mao portion 12a is formed is 1.0 ~ 1.3mm, thus especially can play good effect in the entering in neck portion.
The spacing of planting pore 13 for the part beyond the buffer part 12c planting territory, hair-fields 13 is not particularly limited.When wishing to suppress the sparse sense of bristle, preferably the spacing of planting pore 13 of the part beyond the buffer part 12c planting territory, hair-fields 13 is done narrow.
As shown in Figure 3A, when using the toothbrush 100 not forming buffer part 12c in the past to brush teeth by rubbing manipulation, when pieces 11 is pressed into flank of tooth C, pieces 11 supports each other.Therefore, pieces 11 is difficult to flexure, and bristle tips reduces to the entering in neck portion.
But, as shown in Figure 3 B, use and be formed when not having the toothbrush 1 of the present embodiment of the buffer part 12c of pieces to brush teeth by rubbing manipulation, can suppress pieces interval being planted the situation that when mao pieces of portion 12a 11 is pressed into flank of tooth C, pieces 11 supports each other.Therefore, pieces easily bends, and bristle tips is higher to the entering in neck portion.
In addition, as described so, arrange buffer part 12c pieces interval to be planted mao pieces of portion 12a 11 and make in the toothbrush 1 of the present embodiment of easily flexure, owing to not being the toothbrush spacing of planting pore 12 of entirety expanded, so, the flexible decline of pieces, the sparse sense of bristle can be suppressed, the brushing to tartar can be guaranteed fully.
Further, because buffer part 12c is formed at the tip side of planting territory, hair-fields 12, so can not produce the not enough so sparse sense of bristle of pieces 11, the use sense as toothbrush 1 is excellent.In addition, by being formed with buffer part 12c, thus the circulation of saliva etc. when cleaning in oral cavity, can not be hindered, easy drying, comparatively health after using in addition.
Do not form buffer part 12c owing to planting a mao portion 12b with the front portion of face, pieces 11 more thickly exists, and thus can clean fully the flank of tooth.
Due in addition, a mao pieces of portion 12b 11 is planted when existing in front portion rarelyr, front portion is planted mao elasticity of the pieces of portion 12b 11 and is died down, so, when improving the pressing force of pieces 11 pairs of flank of tooth when cleaning in oral cavity, brushhead 10 becomes easy and face, in the toothbrush 1 of present embodiment, owing to ensure that a mao pieces of portion 12b 11 is planted in front portion fully, even if so the pressing force improving pieces 11 pairs of flank of tooth also can prevent brushhead 10 and face.By improving the pressing force of pieces 11 pairs of flank of tooth, thus more can improve pieces interval and plant the entering of mao pieces of portion 12a 11 to neck portion.
In addition, the invention is not restricted to above-mentioned embodiment.
Planting the arrangement not necessarily lattice-like arrangement of pore 13, also can be staggered or asymmetric geometry etc. other certain arrangement.The arrangement of planting pore 13 is also symmetrical without the need to relative centre axle B.But from the bristle tips of pieces 11 to the viewpoint of the entering in neck portion, the arrangement relative centre axle B preferably planting pore 13 is symmetrical.
In the above-described embodiment, the length direction of buffer part 12c is in the direction from the base end side of brushhead 10 towards top of planting territory, hair-fields 12, and the length direction of buffer part 12c also can be the direction intersected vertically with the center line B planting territory, hair-fields 12.
In addition, buffer part 12c may not be rectangular-shaped.But the shape of buffer part 12c is determined by the arrangement of planting pore 13 adjacent with buffer part 12c.In the asymmetrical situation of arrangement relative centre axle B of planting pore 13, buffer part 12c is the shape of the complexity of non-thread symmetry.
In addition, toothbrush of the present invention also can use as the brush of electric toothbrush.Even if when toothbrush of the present invention is used in the brush of electric toothbrush, also can makes the entering of bristle tips to neck portion and the brushing to tartar and to deposit and use sense is excellent.
