Description
Invention field
The present invention relates to toothbrush and manufacture method thereof, more specifically, relate to the toothbrush and the manufacture method thereof that comprise flexible separate bristle springy zone, the diameter of this separate bristle is bigger than the diameter of traditional soft toothbrush bristle, in use apply simultaneously the active force of the softness of buffering, make it compare, strengthened cleaning action and can not produce bigger injury gingival tissues with traditional soft bristle.
Background of invention
As everyone knows, toothbrush is the use of the toothbrush of hard bristle particularly, may be to particularly gums generation injury of soft oral tissues in the mouth.This injury can show as common gums pit and three types relevant local gums occur and damage: (1) is in gingival edge or at the erosion of the epithelial surface of the diffusion edge at gums-tooth edge, the hemorrhage or trickle from the erosion district simultaneously; (2) except that the gum area of health, also have superficial epithelium significantly break or (3) epithelial surface of bore a hole is rolled, thereby make outside bottom layer tissue is exposed to.Show, when using soft toothbrush rather than medium-hard toothbrush, can obviously reduce extent of injury.See M.Pader,
Oral Hygiene Products and Practice, Marcel Dekker, Inc., 1988,170 pages.
" softness " of toothbrush characteristic, " medium " or " firmly " are directly for " pliability " of toothbrush bristle.And different, it defines the ability of bristle filaments resistance to deformation (as bending) to " pliability " of the bristle of given material together with the diameter of bristle and length; Wherein, " pliability " of filament reduces with diameter increase and bristle lengths increases.Usually, modern toothbrush comprises about basically 0.43 inch (11mm) long nylon brush hair, when bristle diameter in about 0.006 inch (0.15mm)-0.007 inch (0.18mm) or more hour, this toothbrush is classified as " softness ", when bristle diameter when about 0.0080 inch (0.20mm), this toothbrush is classified as " medium ", when bristle diameter at about 0.009 inch (0.23mm) or when bigger, this toothbrush is classified as " hard " or " firmly ".
Use this " softness " bristle,, can not provide removing effect with effective removal plaque, stain and the swill the same than the major diameter bristle though the potential injury that minimizes gums is played an important role.This diameter can apply the sweeping power of enhancing to tooth at about 0.008 inch (0.20mm) or bigger than the major diameter bristle, disperseing effectively and to clean plaque and swill, and wipes stain.
Therefore the such toothbrush of significant need, its can provide have than minor diameter avoid in the mouth soft oral tissues is produced injury and soft " softness " bristle, can provide again to have the larger-diameter soft bristle of removing effect that strengthens.
The invention summary
The present invention includes a kind of toothbrush and preparation method thereof, this toothbrush has the head that has rigidity week frame, the all frames of described rigidity have at least one can be from the transverse holes that wherein runs through, across this hole or a plurality of hole and extend a plurality of bottoms bands (strings), this bottom band is supporting the separate bristle zone, and this bottom band and bristle are flexible by bending and rotation in use.Each separate bristle and support foot band are in use because bending and rotation and crooked ability, especially each separate bristle around the lateral rotation of the longitudinal axis of its support foot band, bristle " pliability " is reduced, and general toothbrush are impossible realize; Wherein, each bristle is fixed in the head toothbrushes material un-rotatably.
Also can be by using thinner, more soft bottom band and the bottom band being placed in the rigidity week frame with pressured state, make band outwardly-bent or arch from the plane that rigidity week frame is set in bottom come out further to reduce " pliability " of bristle.When with toothbrush application on tooth and gums the time, this outside ability that the bottom band that shows enhanced absorption part brushing pressure of encircleing.Unexpectedly, in toothbrush of the present invention, use typical nylon brush hair, " pliability " of bristle significantly reduces, thereby can use larger-diameter bristle, be that diameter is at about 0.008 inch (0.20mm)-0.015 inch (0.38mm) or bigger bristle, can be used for more effective cleaning, yet, the pliability characteristic of bristle diameter at 0.006 inch (0.15mm)-0.007 inch (0.18mm) or littler " softness " toothbrush also is provided simultaneously.
In the second embodiment of the present invention, the rigidity of head toothbrushes week frame have more than one can be from the transverse holes that wherein runs through.Rigidity week frame can have two, three, four, five or more a plurality of can be from the transverse holes that wherein runs through, this hole can have identical or different area.Comprise a plurality of bottoms band in each transverse holes, a plurality of bottoms band forms flexible lattice springy across arbitrary particular bore, extends the separate bristle zone from these flexibility lattice.As mentioned above, the pressurized degree of each lattice by changing the solid bottom band, thus the degree that particular bin is outwards encircleed will increase or reduce, and correspondingly influences the flexibility of area of bristles, to obtain " pliability " of desirable bristle.
Head toothbrushes of the present invention have have at least one can be from the rigidity week frame of the transverse holes that wherein runs through, the manufacturing of this head toothbrushes may further comprise the steps: at first, place preformed bristle sub-component between two parts of mould, it has a plurality of separate bristle filaments that are connected to the bottom band and therefrom extend; Then, the thermoplastic of toothbrush frame structure is injected mould and forms rigidity week frame, and the two ends of bottom band are permanently locked onto in the position in the framework, in rigidity week frame, run through each hole sub-component is installed.Then, when the molten thermoplastic material cooling that is used to form rigidity week frame, the all frames of rigidity will shrink, reduced makes and will be placed with pressured state across the bottom band that extends on it, and the bottom band will outwards encircle from the plane that rigidity week frame is set, thereby make each bottom band will show the flexibility springy of enhancing.
