Description

Method with toothbrush and location toothbrush head of controlled head movement
Technical field
The present invention relates to toothbrush, particularly relate to toothbrush with controlled head movement and the method for locating toothbrush head.
Background technology
Traditional toothbrush comprises a plurality of the same bristle tufts, and every cocooning tool has one first end and one second end, and first end is held and is captured in the toothbrush head and is fixed in the latter, and second end is free end and is used to brush teeth.Different bunches free end constitutes an enveloping surface, and this enveloping surface can the distortion a little by means of bristle is crooked when touching by the brush surface, but can not cooperate a surface with complicated shape fully.Such complex surface occurs in mouth, and tooth generally is in " C " shape case of bending in upper and lower jaw herein, and therefore every row's tooth has the outer bend and the recessed interior curve of protrusion.
In the process of brushing teeth, the user makes hope that bristle is fit to tooth express by the curved profile that operate toothbrush effectively makes bristle suitably be deformed into denture.Thisly just cause the excessive wear of the flank of tooth and gum, and toothbrush conforms to suitably so that required cleaning is provided with tooth near the strong operation of tooth.
It is disclosed in the prior art so that make bristle meet the toothbrush of dentition profile to have a deflection neck between toothbrush head that contains bristle and handle.The example of this deflection neck toothbrush is included in United States Patent (USP) 759,490 and 4,520, the multiple toothbrush that discloses in 526.It is flexible that United States Patent (USP) 759,490 is created neck by means of placement deflection elastomeric material between rigid head portion and handle, and this deflection elastomeric material can strengthen with second kind of this type material.And that United States Patent (USP) 4,520,526 is created neck by means of following alternative method is flexible: or take a part of material away from the top and bottom portion of toothbrush stem, or in neck, have an oval hole that reaches opposite side from a side.This deflection elasticity toothbrush stem allows bristle head relative curved handle when the user applies excessive strength, reduces the danger of damage tooth and gum whereby.Yet this flexing method does not allow the user to have following ability: the special semicircle in oral area surface that control toothbrush head profile becomes cleaning with water, and to avoid in first example, applying the needs of excessive strength.
United States Patent (USP) 4,333,199 disclose a kind of toothbrush, and its head can pivotally be installed on the helical spring that is positioned at recessed handle top, so that be suitable for rotating when head is applied on the tooth and inclination.Yet in the oral area surface semicircle that this deflection action can allow toothbrush head roughly to follow just to be cleaned with water, it does not provide by the directly actuated toothbrush head motion of user, inclination and spinning movement.
PCT International Application No. WO 89/10076 discloses a kind of toothbrush, and it has angle between the toothbrush head of change and the handle so that the location toothbrush head makes it the ability parallel with the denture arch section.WO 89/10076 discloses a kind of toothbrush, and it has the handle that can be pivotally connected to head, handle is made of the upper and lower sidepiece of a pair of rigidity that separates herein, and these sidepieces can pivotally link together and can vertically move mutually.As an alternative, the upper and lower sidepiece of the rigidity that separates can connect by an elasticity interlayer, and this also allows them can vertically move mutually.Use a kind of like this by toothbrush rigidity sidepiece the handle that can pivotally connect that vertically moves control and head accurately to control the toothbrush head position be difficult at most.It is because the following fact that this accurate control lacks: the connection that can pivot lacks rigidity or resistance, has the trend that makes the toothbrush head overexercise; Move with extent of elasticity and substitute to use an elastic layer can limit head with being directly proportional.
Therefore, have a kind of like this demand in toothbrush art: the user can more accurately control the position of toothbrush head, so that head is positioned to the state that conforms to the denture curved profile.
Summary of the invention
Therefore, the object of the present invention is to provide a kind of user of having to control the method for the toothbrush and the location toothbrush head of head.
A kind of user of having according to the present invention can control the toothbrush of head, and it comprises: an elongate handle, and it has a longitudinal axis, a upper side and a downside; But described handle is made up of the trunk portion of one first relative stiffness and overall S-shaped bending and second elastic deflection of an opposition and the part of overall S-shaped bending; One end of the described first overall S shape sweep stretches into a base portion and the other end stretches into a neck, and described neck is being equipped one and flattened head, described head have one comprise many bristle tufts of stretching out from here above; It is characterized by, the S shape sweep of described opposition determines that has an one or more hole and the one or more elongation 8 word figures in hole down gone up.
According to a kind of method of locating toothbrush head of the present invention, it comprises: molding one is aforesaid toothbrush; By the S shape sweep of described first relative stiffness around the hole on described is exerted pressure, but and be pressed on the there simultaneously and assign to locate described toothbrush head with the S shape bend of the described second relative elastic deflection of its opposition.

The specific embodiment
Referring now to accompanying drawing,, identical Ref. No. is applicable to same or similar member in several accompanying drawings, especially referring to Fig. 1, shows a toothbrush 12 therein.Fig. 1 be round longitudinal axis A-A and have a upper side 13 and a relative downside 15 one the perspective view of toothbrush of the present invention, its toothbrush has a head 14 of making integral body and stretching out from the latter with neck 16, this neck is made integral body with handle 18 again and is stretched out from the latter, and this handle is made integral body with base portion 24 and stretched out from the latter.Have a face 20 on the upper side 13 of head 14, stretch out many rows bristle tufts 22 vertical with longitudinal axis A-A from this face.
According to the present invention, head 14 can be labeled as in Figure 1A in the vertical plane of V with respect to handle 18 deflections, but is rigidity basically for handle in the horizontal plane that is labeled as H among Figure 1A.This flexibility results from the following fact: handle 18 is many parts shape, that is to say to make a plurality of partial status of being made up of at least two kinds of visibly different materials of elastic modelling quantity; A part is made by the plastics of relative stiffness, but and another part is made by the elastomer of elastic deflection.The parts of plastics of relative stiffness comprises vertical trunk 26 of an overall S-shaped bending, and it extends to from toothbrush stem widens base portion 24.And but the elastomer portion 28 of elastic deflection also is overall S shape curved shape, and with 26 one-tenth antagonistic relations of vertical trunk of overall S-shaped bending, but so that the opening of the vertical trunk of rigidity of overall S-shaped bending by elastic deflection elastomer portion 28 closures of overall S-shaped bending.Simultaneously, but the elastic deflection body part 28 of the overall S-shaped bending of vertical trunk of the rigidity of S shape bending 26 and opposition forms one is 8 elongated word figures totally.The interlocking S shape that forms the overall figure of 8 words is crooked determines two holes, i.e. the last hole 30 of proximate neck 16 and one the following hole 32 of adjacent base 24 more more; The cross-sectional area in two holes preferably about equally.
Hole 30 and 32 has enough cross-sectional areas, but so that give power that the relative stiffness trunk portion 26 center on hole 30 applies greater than the relative elastic deflection part 28 that centers on hole 30 of giving opposition or when giving the power that applies around the relative stiffness trunk portion in hole 32 down of opposition the user, the bristle of connection supports head 14 and departs from a position along the direction of toothbrush upper side 13.The power that is caused by the user in this control is used in Fig. 1 with longitudinal axis A-A relative arrow in an acute angle and is described.Therefore, but the user can give around the relative elastic deflection part 28 in last hole 30 with a suitable angle and apply the power that applies around the corresponding relative stiffness trunk 26 in last hole 30 greater than giving, so that bristle supporting head 14 can be offset to a position in opposite direction, promptly leave the upper side 13 of toothbrush.
The interlocking S shape sweep that forms handle is shown in longitudinal axis A-A and substantially equally separates on every side in Fig. 1; Yet, in alternate embodiments more of the present invention, the S shape sweep of interlocking can be more near the place ahead of longitudinal axis A-A, as Fig. 2, perhaps more near the rear of longitudinal axis, as Fig. 3.Also have, be generally the ellipse with a relative short and small axis of pitch for a longer longitudinal axis at hole among Fig. 1 30 and 32, its longer longitudinal axis can be to align with toothbrush longitudinal axis A-A or in an acute angle with the latter; Simultaneously, these holes also can be round, and have axis of pitch length much bigger for their longitudinal axis length, shown in Fig. 2.As an alternative, hole 30 and 32 can be crescent, as shown in Figure 8.
According to the present invention, the trunk 26 and the base portion 24 of head 14, neck 16, the bending of S shape are shaped as an one-piece machine member, and its material is polypropylene or a kind of other plastics with similar relative stiffness structure of a kind of relative stiffness, and for example polyamide is a nylon; Perhaps a kind of polyester or a kind of copolymerization fat, for example PETG (PET); Perhaps a kind of poly terephthalic acid cyclohexylidene two methylene vinegar (PCTA) of sour modification; Perhaps a kind of cellulosic plastics; Perhaps styrene-acrylonitrile (SAN) or acrylonitrile butadient styrene (ABS).Polypropylene or other rigidity plastics would rather have from 40 to 110 Xiao A hardness scope, and from 60 to 110 is better, and preferably from 80 to 100.The polypropylene that is suitable for can by the flood of 75603 Texas Lang Weiyou now Man (Huntsman Corporation, Longview, Texas, 75603) provide, its trade name is the graceful now polypropylene P4G3Z-039 of flood.
But the elastomer S shape sweep 28 of elastic deflection can be used various materials relatively, and especially thermoplastic elastomer (TPE) (TPE) is shaped.But the acceptable TPE material of S shape elasticity of flexure body portion 28 usefulness of elastic deflection relatively comprises the styrene block copolymer of styrene-ethylene/butylene-styrene (SEBS) type, s-B-S for example, styrene-isoprene-phenylethene and related copolymers, and thermoplastic polyurethane (TPU) or a kind of thermoplastic hard rubber of forming by the mixture of polypropylene and EPDM (ethylene propylene diene terpolymers) (TPV), described TPV can be provided as at United States Patent (USP) 5,393, the Santoprene (trade mark) or the Vyran (trade mark) that describe in 796, another kind of TPV is made up of the mixture of a kind of polypropylene and natural rubber, Santoprene and Vyran all are the advanced elastomer LP of system (the Advanced Elastomer Systems LP by Akron city, 44311 Ohio, Adron, Ohio 44311) elastomer sold.In addition, Zui Jia TPE is the Dynaflex G6713 (trade mark) that is sold by the GLS Corp. (Illinois 60013 for GLS Corp., Cary) in city in the 60013 Yi Linuosi state cards.These and other elastomers that are suitable for typically have from about Xiao A hardness of 1 to 94, and about 15 to 60 is better, and preferably about 15 to 40.
But the elastomeric material of elastic deflection can be formed and cover around the handle 18, elastomer again the injection moulding zone as shown in sectional drawing Fig. 4.But the elastomer S shape sweep of elastic deflection is shown as zone 38 and 40 in Fig. 4, and they are separated by the cross section of the relative stiffness trunk 26 of the overall elongated and S shape bending that shows.The elastomer S shape of the trunk portion 26 of relative stiffness and relative deflection partly promptly the degree of flexibility in zone 38 and 40 all can come further to be controlled by means of changing its thickness, more or less flexible promptly is provided.
If toothbrush inscape for relative stiffness, be the trunk portion 26 of toothbrush head 14, neck 16, relative stiffness and overall S-shaped bending and the profile that base portion 24 needs a substantially transparent, can adopt polyester, for example PETG or a kind of copolyesters, for example PCTA polyester or SAN, perhaps a kind of cellulosic plastics, for example cellulose acetate propionate (CAP).If for the elastomer inscape of the relative deflection of toothbrush, i.e. the profile of a kind of substantially transparent of S shape elasticity of flexure body portion 28 needs of deflection relatively, some TPE, or TPUS, perhaps ethylene-vinyl acetate copolymer (EVA) material can be used.A kind of TPE of substantially transparent of the best can be by 02861 Lang Te island handkerchief mound Kate's (the Teknor Apex Company of Tai Kenuoali Ces Co.,Ltd, Pawtucket, Rhode Island 02861) provide, it sells commercial label is 96-E0807A-03NT WAT CLR.
Alternate embodiments more of the present invention can be included among the upper and lower section of the shaping handle 18 that totally is 8 word figures, be not only two holes that discussed the front, and an independent hole or one group of a plurality of hole, i.e. three, four, five or six holes are arranged in each section.Have in handle 18 under two kinds of situations of single or this one group of hole, the trunk of relative stiffness all forms or single hole hole or first side of hole in groups, and the elastomer formation of a relative resilient deflection or single hole or second side of hole in groups.Hole can be totally to be half moon-shaped, totally to be oval or overall rounded, and their longitudinal axis is aimed at toothbrush longitudinal axis A-A or in an acute angle with the latter usually.This aggregative hole can all be positioned at substantially the toothbrush longitudinal axis around, in other words in its both sides.The illustrative of these alternate embodiments is described and is displayed among Fig. 6,7 and 9.
Because the embodiment of the invention contains the base portion that broadens that adopts all bicomponent structures, increases the weight of typical toothbrush significantly, therefore for impost is minimized, base portion can be a hollow.As shown in Figure 5, a kind of like this hollow base can be made by a kind of relative stiffness polypropylene shell 34 of inner injection mo(u)lding, but but this shell comprised elastic deflection elastomeric material elastic deflection elastomeric material 36 round.As an alternative, as shown in figure 10, the present invention can comprise a kind of typical narrow toothbrush base portion, thereby reduces the weight that increases.
Many parts combined toothbrush of the present invention can be with traditional injection molding technology molding, and this technology is well-known in this technology.For example, according to the present invention, but the elastomeric material of elastic deflection part can be by means of in second injection step injection mouldings again around handle 18 after first injection step of skeleton in other words of injection moulding framework, and described framework is made up of the handle stem portion 26 and the base portion 24 of the head 14 of embedding bristle, neck 16, relative stiffness.This framework is placed in second mould in this second injection step, but with the elastomeric material of elastic deflection around its handle 18, more specifically say so be expelled to this mould around the relative stiffness trunk portion 26 that extends to neck 16 basal planes from base portion 24 among.
