This invention relates to a tweezers, and in particular, a means and method for producing a single-piece tweezer with small and big tip.
Tweezers are used for a variety of purposes, including hair removal, or for medical purposes such as sliver removal. The typical tweezer has diverging arms with pointed tips. When the arms are compressed by the user, the tips converge and can be used to grip very small items such as hairs, slivers, and the like, and extract them.
By looking at prior art, multiple advancements have been seen in tweezers construction. For instance, a U.S. Pat. No. 4,761,028A relates to single-piece tweezers. The means and method for forming tweezers and tweezers handles out of a single piece of material. The tweezers consist of unitary body including two parallel spaced apart arms which extend from an integrally formed heel end portion The ends of the arms opposite the heel end portion comprise tweezer tips or can be connected to replaceable tweezer tips. In a preferred embodiment, the single piece tweezers are produced by electrical discharge machine process which produces very accurate and precise cuts.
A U.S. Pat. No. 2,006,0175853A1 relates to Tweezer. The tweezer is comprised of arms diverging from a base, wherein each arm has a first section closest to the base that diverges from a straight line perpendicular to the base, and a second section furthest from the base that converges toward a straight line perpendicular to the base.
A Free-standing tweezer bearing U.S. Pat. No. 4,852,929A discusses a tweezer i.e. constructed so that it is free standing in a vertical position with its gripping end positioned upward.
A WO patent 2,012,004885A1 relates to hair tweezers. The proposed hair tweezers have a bend section from which a pair of opposing plate-shaped gripping sections extend in the longitudinal direction, and opposing gripping surfaces are respectively formed on the ends of the gripping sections which are located on the side facing the bend section. The hair tweezers do not cause a problem in that, when the hair tweezers are in use, the ends on the side on which the gripping surfaces are formed are displaced in the vertical direction, which intersects the longitudinal direction, to make it difficult for the user to grip a targeted unwanted hair. The thickness of a bend section is equal to or greater than the thickness of the portions of a pair of gripping sections which are not included in the bend section. The pair of gripping sections are respectively provided with thin sections, which have a small thickness, located between the bend section and the ends having the gripping surfaces formed thereon.
A US patent 2,0150,148840A1 discusses another variation of tweezers. The Tweezers are disclosed for example folding tweezers. In some implementations the tweezers include a protective member and a tweezer member pivotably mounted on the protective member to allow the tweezer member to rotate relative to the protective member between a first position, in which the tweezer member is protected by the protective member, and a second position, in which the tweezer member is exposed. The tweezer member may be mounted adjacent the distal end of the protective member, and may include a portion configured to extend beyond the distal end of the protective member when the inner tweezer member is in the first position.
By looking at prior art multiple there are multiple solutions that have been presented in prior art regarding bringing advancements in various types of tweezers designs and their functionality. However, these solutions are limited and restricted to their conventional systems. The current invention aims to provide two types of tips i.e., small and big tip. Wherein both tweezers are thin blade tips with fiber.

Tweezers are a well-known, simple mechanical device that is produced in many different forms to fulfill various needs such as hair removal, wound debridement and generally manipulation of small things. The present invention relates to a tweezer design with big and small tips.
The present invention as per its preferred embodiments proposes a tweezer structure wherein the invention relates to tweezers, in particular, cosmetic tweezers with small and big tips, comprising two legs extending in the longitudinal direction, which are connected to one another with their one end and the free ends of which form inner jaw surfaces, so as to hold something between both jaw surfaces, wherein both legs including the connecting area consist of a metallic glass or of an amorphous metal in one piece. In the case of such a one-piece production, the entire pair of tweezers with all of its parts and areas is produced in a single injection molding process, so that it is not necessary to subsequently fasten the legs of the tweezers to one another and extensive machine finishing operations are no longer necessary.
With the injection molding in one piece, the legs of the tweezers and the connection location have the final shape, so that subsequent profiling, ribbing, ribs are not necessary and so that even embellishments and the application of a logo already exist with the first operating process. A high degree of creative freedom, therefore, exists. A pleasing visual appearance can be attained, because more design and freedom/leeway/variances are at hand, in particular, due to certain designs of the surfaces, such as ergonomic shaping and/or ribbing.
The chosen material is highly elastic, free from corrosion, and has a high durability and a low wear/low abrasion. The production effort is extremely low. The number of production steps (stamping, punching, shaping, among others) is significantly reduced.
Tweezers may be made from thermoplastic materials that have shape memory, such as polypropylene, polyethylene, styrene, and so on. In addition, tweezers may be made from metals that have shape memory, such as tin, aluminum, iron, or alloys of such metals. Preferably the tweezer is made of a thermoplastic material with shape memory, or aluminum.
While a specific embodiment has been shown and described, many variations are possible. With time, additional features may be employed. The particular shape or configuration of the platform or the interior configuration may be changed to suit the system or equipment with which it is used.
Having described the invention in detail, those skilled in the art will appreciate that modifications may be made to the invention without departing from its spirit. Therefore, it is not intended that the scope of the invention be limited to the specific embodiment illustrated and described. Rather, it is intended that the scope of this invention be determined by the appended claims and their equivalents.
