Description

Safety razor
The present invention relates to the shaving device, relate to a kind of safety razor blade unit, this unit has the blade of a band cutting edge at least, and this blade cutting edge utilizes handle can cross the surface of scraping surface skin and moves, and this blade unit is contained on this handle.Blade unit removably is contained on the handle, make and when the sharpness of blade is reduced to inadequacy, can change this blade unit with a new blade unit, perhaps blade unit also can permanently be contained on the handle, can throw away whole shaver when a blade on it or all blade rusts.Shaving blade unit generally comprises backplate and cover plate, the former forms the surface of a contact skin, be positioned at the place ahead of blade (or a plurality of blade), the latter contacts skin, be positioned at the back of blade (or a plurality of blade), cover plate and backplate are to play an important role in the parameter forming so-called " shaving geometry ", and during shaving, these parameters are determined orientation and the position of blade with respect to skin.The present invention is specifically related to the backplate and/or the cover plate of shaving blade unit.
The preliminary step before the shaving generally be with the shaving agent for example shaving soap etc. be coated in and be beneficial to the shaving operation on the skin.An effect of shaving agent for example is lubricated skin, so that blade more easily slides on skin.But in some cases, can not smear skin well.And after finishing, shaving also must wipe most of shaving agent.Therefore preferably can provide a kind of like this shaver, this shaver has the device that can discharge shaving improver or medium during shaving.Constituted a kind of blade unit as everyone knows, this unit has a kind of bar part, and lubricant just oozes out from this bar part very slowly during shaving.It is useful that this lubricious strip has been proved to be, and still, the active material that it can be joined in the bar part by for example manufacture process is limited, and the speed that lubricant is discharged is too slow, thereby still needed to smear fully skin before shaving.Also proposed a kind of shaver, it comprises a chamber that liquid shaving agent is housed and soaks into the sponge of this shaving agent and the shaving agent is discharged to system on the shaver workpiece by the finger pressure extruding.Yet, still still need such shaver, this shaver is suitable for sending shaving agent goods gradually and not needing the user to operate especially in the whole length of life of shaving blade unit, for example refills reservoir or product is discharged when needed.
The invention provides a kind of safety razor unit, this unit has at least one elongated blade and skin engagement parts, this attachment form expose in case during shaving with the surface of skin contact, above-mentioned attachment comprise and manyly are used to keep the appropriate section shaving to improve the hole of goods, above-mentioned hole vertical and horizontal on skin contact surface distribute, and each hole opening from the teeth outwards.
Skin engagement parts of the present invention can send the material that can not comprise in the prior art lubricious strip, because these materials can not bear machined.It can be a kind of formulation example such as gel that shaving improves goods, and it is designed to have the property of solubilizing that needs, and can remain in the hole motionless easily owing to the characteristic of goods.These goods can be the fluid or the gels of viscous, have the characteristic miscible with water, or may be dissolved in the water, make the goods fluidify, so that discharge from the hole, water are always arranged generally when shaving.
For the ample supply shaving improves goods, prolong the service life of blade unit, the inner in hole communicates with a storage chamber, and this storage chamber is equipped with the shaving that sends by the hole and improves goods.
The hole should be configured to have the array of abundant combined density, to guarantee smearing goods satisfactorily during the shaving.When keeping reasonably well forming skin contact surface, the face width between adjacent hole should be suitable for the 5%-100% of this hole maximum transverse size.
In preferred structure, the hole is columnar, promptly has the sidewall of smooth curved, and the preferably upright cylinder in hole, and its axis is substantially perpendicular to skin contact surface.But other shape also is feasible, and for example cross section is hexagon or oval shape.The degree of depth in hole for example approximates the radius in hole less than the diameter in hole.The thickness of material is less than the hole radius between the adjacent hole.
The hole is preferably formed on the antetheca in chamber, improves the supply of goods with the shaving that keeps fluid, and each hole is communicated with the chamber by a restricted opening, and this opening is controlled flow of articles and gone into the flow in hole, thereby is controlled at the release on the skin contact surface.
Skin engaging member can be the backplate of blade unit, and perhaps it can be for example cover plates of other parts.
Describe embodiment with reference to the accompanying drawings in detail, the present invention may be better understood thus, and these accompanying drawings are:
Fig. 1 is the perspective view of the incision of shaving blade unit of the present invention;
Fig. 2 is the view in transverse section by blade unit.
Be shown in safety razor blade unit among the figure and comprise that the pair of series formula is contained in blade 1 and 2 on the bearing support, is fixed on the framework and constitutes the backplate 3 of hollow storage chamber 4 and for example be the cover plate 5 of lubriation material strips, this lubriation material bar is positioned at the blade back by bracket supports.
The surface 9 that backplate comprises upper wall 8 and exposes, this surface configuration becomes to contact with skin during shaving.Form many holes 10 that are configured to regular array in this wall, this array extends at the length and the width of skin contact surface.The hole is configured to many stringers, and triplex row is arranged in an example shown, and the hole vertical misalignment in the adjacent lines, thereby it is very near that the hole is separated by.The hole is circular, and in the embodiment shown, all holes have same diameter.
Each hole 10 is communicated with storage chamber 4 by hole 12, and hole shown in the figure 12 has restricted area at the hole inner end.The circulation area of selecting hole, the feasible shaving that is included in the storage chamber 4 improves goods and can flow to controlled speed in the hole, goods are assembled in this hole, and remain in the hole under the influence of for example flowing product surface tension characteristics, thereby can discharge at any time during shaving.Limited hole plays a part also to prevent that shaving auxiliary agent goods from turning back to storage chamber from the hole, thereby the goods that remain full of of hole.In fact, storage chamber will comprise the shaving auxiliary agent goods of abundant amount, and the whole service life that can keep blade unit is promptly until the blade rust.
Shaving auxiliary agent goods preferably have lubrication property, and other characteristic that perhaps has another kind or also have is in addition for example thought favourable humidification characteristic during shaving.Goods will have enough flowabilities, so that goods can flow into the hole from storage chamber, goods will have enough viscosity and surface tension characteristics, thereby can remain in the hole and can not be freely flow out from the opening in hole, and when sliding on skin on the backplate surface during the shaving,, can little by little send owing to become easier when mobile with water contact for example.
Providing shaving to improve goods to the hole is not important feature, within the scope of the present invention be, the hole is made to definite shape and size, improve goods and keep these goods thereby during a shaving, assemble endermic shaving, thereby form improved lubrication in the incipient stage of shaving subsequently up to shaving next time.
