Description

Dental-floss device
Technical field
The present invention relates to a kind of oral care implement for cleaning teeth, particularly a kind of dental-floss device.User is handled this dental-floss device, and the dental surface of teeth space both sides is cleaned.When not being used, this dental-floss device is " two dimension " structure.In use, this dental-floss device can be " three-dimensional " structure from " two dimension " reconfiguration.
Background technology
Utilize the technology of the dental surface of dental floss cleaning teeth space both sides, it is documented, the mankind have used centuries.Simultaneously, the various devices of disclosed assisted control dental floss, numerous.Wherein, No. DES227896, United States Patent (USP) discloses a kind of dental-floss device.This dental-floss device comprises a dental floss bracket and a handle that is used for grasping.This dental floss bracket roughly is " U-shaped " structure, comprises a base portion; Extend first support bar and second support bar from this base portion; One section dental floss, its two ends are fixed on respectively the free end of the first support bar and the second support bar.The handle of this dental-floss device has an end to be fixedly connected with the base portion of dental floss bracket.Handle is axis and be fixed on the angle between the axis longitudinally of the dental floss on dental floss bracket longitudinally, is roughly 90 degree.This dental-floss device structurally has following features: if disregard the thickness of dental-floss device itself, so, the handle of dental floss bracket and dental-floss device roughly is positioned on same plane, is two-dimensional structure.This paper agreement: the handle of this dental floss bracket and dental-floss device is the dental-floss device of two-dimensional structure, is called " two-dimentional dental-floss device ".
Usually adopt the injection forming process, the dental floss fiber is fixed in the first support bar of dental floss bracket and the free end of the second support bar.If the employing multi-cavity mold, an injection moulding just can be produced a plurality of dental-floss devices.For the manufacture of the dental floss of dental-floss device, be generally nylon or polyester filaments, or other high modulus fibre long filament.The fineness of fiber is roughly between the 300-900 denier.Dental floss bracket and dental floss handle portion generally adopt the suitable plastic material manufacturing of polypropylene or other hardness.Had the method for a lot of manufacturing dental-floss devices to be disclosed, therefore not to repeat here.
Aforementioned No. DES227896 disclosed dental-floss device is two-dimensional structure, therefore is easy to make, and is convenient to packing and carries.But this dental-floss device also has obvious defective: when being used for cleaning molar, dental floss can not arrive at some position of molar.
United States Patent (USP) can be regarded as a kind of improvement of No. DES227896, United States Patent (USP) for No. DES274375.No. DES274375 disclosed dental-floss device of United States Patent (USP) also comprises a dental floss bracket and a handle that is used for grasping.Compare for No. DES227896 with United States Patent (USP), its improvements are: the axis longitudinally of the handle that No. DES274375, United States Patent (USP) and be fixed on the angle between the axis longitudinally of the dental floss on dental floss bracket is roughly 0 degree.Usually, such dental-floss device, the axis longitudinally of its handle and the angle between the axis longitudinally that is fixed on the dental floss on dental floss bracket at 0 degree between 60 degree.
United States Patent (USP) structurally still has following features No. DES274375: if disregard the thickness of dental-floss device itself, so, the handle of dental floss bracket and dental-floss device roughly is positioned on same plane, is two-dimensional structure.Therefore, United States Patent (USP) still belongs to " two-dimentional dental-floss device " for No. DES274375.
Owing to being two-dimensional structure, so United States Patent (USP) has advantages of " two-dimentional dental-floss device " for No. DES274375: be easy to make, and be convenient to packing and carry.And because the angle between the axis longitudinally of the axis longitudinally of its handle and dental floss is more reasonable, thereby it can clean molar better.But, when using its cleaning molar, still difficult and effort.
United States Patent (USP) discloses a kind of dental-floss device No. DES274375.It also comprises a dental floss bracket and a handle.This patent has and aforementioned two characteristics that patent is different: even disregard the thickness of dental-floss device itself, the handle of dental floss bracket and dental-floss device is not positioned on same plane yet.This dental-floss device has three dimensional structure.This paper agreement: the handle of this dental floss bracket and dental-floss device is the dental-floss device of three dimensional structure, is called " three-dimensional dental-floss device ".
This " three-dimensional dental-floss device " has following advantage: its dental floss can arrive at any position of any tooth (comprising molar), so it can clean the teeth up hill and dale, and easily handles.But, " three-dimensional dental-floss device " also has weak point: owing to being three dimensional structure, so manufacturing cost is higher, and is not easy to packing and carries.
US Patent No. No. 20040134512A1 (it designs artificial designer of the present invention) discloses a kind of dental-floss device.This patent has proposed the concept of " two-dimentional dental-floss device is transformed to three-dimensional dental-floss device " first in the whole world.The disclosed dental-floss device of this patent has following feature: when not being used, this dental-floss device is " two-dimentional dental-floss device " structure.In use, its " two-dimentional dental-floss device " structure can be transformed to " three-dimensional dental-floss device " structure.Whereby, this dental-floss device both had advantages of " two-dimentional dental-floss device ": be easy to make, and be convenient to packing and carry; Simultaneously, have advantages of again " three-dimensional dental-floss device ": it can clean the teeth up hill and dale, and easily handles.
But, United States Patent (USP) has the following disadvantages for No. 20040134512A1: after this dental-floss device is transformed to " three-dimensional dental-floss device " from " two-dimentional dental-floss device ", must by the support of (with a tightening device) support component, just can make " the three-dimensional dental-floss device " that form after conversion have firm structure.This just need to arrange support component and tightening device on this dental-floss device, thereby makes the structure of this dental-floss device more complicated that becomes.
US Patent No. No. 20050133058A1 (its designer also is designer of the present invention) also discloses a kind of " it is three-dimensional that two dimension becomes " dental-floss device.This dental-floss device has a first handle and a second handle.The apart segment distance of first handle and second handle, and have respectively an end to be connected with the base portion of dental floss bracket.In their junction, the first hinge and the second hinge are set respectively.When not being used, this dental-floss device roughly is " two-dimentional dental-floss device " structure.During use, user need to reverse the handle of this dental-floss device, and first handle and second handle are drawn close each other, holds with a firm grip and pushes down first handle and second handle.This moment, dental-floss device was " three-dimensional dental-floss device " structure.This dental-floss device needn't just can make " the three-dimensional dental-floss device " that form after conversion to have firm structure by the support of support component, and is therefore relatively simple for structure.
This dental-floss device has following feature: reverse first handle and the second handle of dental-floss device when user, when dental-floss device is transformed to " three-dimensional dental-floss device " from " two-dimentional dental-floss device ", user will bear the counteracting force that handle applies.If the axis longitudinally of the first hinge (with the second hinge), and the angle between the axis longitudinally that is fixed on the dental floss on dental floss bracket is in 90 degree left and right, and this counteracting force is smaller.If the axis longitudinally of the first hinge (with the second hinge), and be fixed on the angle between the axis longitudinally of the dental floss on dental floss bracket smaller (such as reaching 60 degree), this counteracting force just becomes larger.During use, user must be used larger pressure pressing handle, relatively effort.
On the other hand, if the axis longitudinally of the first hinge (with the second hinge), and the angle between the axis longitudinally that is fixed on the dental floss on dental floss bracket larger (such as reaching about 90 degree), so, the distance of being separated by between the tail end of first handle and the tail end of second handle will be distant, the space that dental-floss device takies is just larger, is not easy to packing or carries.Therefore, be necessary to arrange the axis longitudinally of the first hinge (and second hinge) and the angle between the axis longitudinally that is fixed on the dental floss on dental floss bracket smaller (such as being set to 45 degree left and right).So, user must apply larger pressure, reverses and pressing handle, " two-dimentional dental-floss device " could be transformed to firm " three-dimensional dental-floss device ".When causing using dental-floss device, this relatively requires great effort.
In the second embodiment of No. 20050133058A1, US Patent No., a kind of scheme that reduces this counteracting force has been proposed, that is: with the thickness of first handle (and second handle) near the part zone of the first hinge (or second hinge), construct thinlyyer.Although can reduce like this counteracting force that the handle of dental-floss device applies user,, therefore the steadiness of dental-floss device also can reduce.During use, dental floss bracket can slightly swing, and can reduce the effect that cleans the teeth like this.
In sum, a kind of easy-to-use, simple in structure, " it is three-dimensional that two dimension becomes " effect that cleans the teeth excellence dental-floss device of Design and manufacture seems necessary.
