Abstract

A knife blade (1) which is used for cutting is clamped between two thin hard plates (5) or embedded in the thin object (7) of the hard plastic. The knife blade (1) is arranged in a long and narrow opening (11) or open slot, and forms a sharp cutting angle with the long and narrow opening (11). The front guide element of the knife blade (1) is realized by two side faces (13) of the long and narrow opening (11). The long and narrow opening (11) further forms the effective protection element of the cutting edge (3) of the miniature cutter.

Description

Micro-knife for open envelope

This invention belongs to the miniature cut paper cutter that is used for opening mail.

Having known has several cutting blade and leading cut paper cutters to element of being equipped with, and such cutter or create independent apparatus perhaps is combined on other article.

Italian utility model to the applicant's application is numbered No.202477, submits on March 19th, 1985, and on November 24th, 1986 went through, and can be used as reference.

The target of this invention is to improve above-mentioned cut paper cutter; utilize fairly simple structure to realize this goal; for example can consider blade is inserted paired thin hard object; in the card that has sealed as plastics; perhaps insert in the object of similar duroplasts; simultaneously cutting edge is granted asylum, so just can realize a kind of improved min-cutter, this cutter not only simply but also safety.

It should be noted that according to this invention, this improved cutter that is used for opening mail, the simplification by means of design can provide a kind of microminiature cutter as thin as a wafer, and this cutter is applicable to many aspects.

In other words, this min-cutter can be installed on many different article, on ruler, the cap of a pen, stationery and other articles for use, and install to such an extent that the articles for use surface that combines with it parallels, perhaps perpendicular with it, and be applied in the occasion of parallel installation, a suitable spacing is set, to be convenient to that min-cutter itself inserted envelope or similarly in the articles for use between this cutter hub and articles for use surface.

Described min-cutter comprises the body and the director element of cutting tip substantially, blade body is clipped in two thin hardboards that are coupled, perhaps be embedded in the thin object of duroplasts, and this blade body is positioned in the bottom of slotted opening, and forms a sharp-pointed cutting angle with this slotted opening; Director element is formed by the side of slotted opening itself, because each element arranges like this that in cutter this slit will be formed the effective protecting component of min-cutter cutting edge.

Utilize quoting as proof in detail of accompanying drawing that the present invention more carefully is illustrated now, these accompanying drawings only have exemplary meaning.

Fig. 1 is according to this invention, is used for the partial side view of the min-cutter in bight, card garden;

Fig. 2 is the partial side view that is used for the min-cutter of card oblique angle portion;

Fig. 3 is the partial elevation view of the min-cutter on Fig. 1 and 2;

Fig. 4 is according to this invention, the limitation side view of min-cutter, this min-cutter be contained in its tool element at regular intervals on;

Fig. 5 is the plane of the min-cutter on Fig. 4.

Demonstrate from accompanying drawing, min-cutter blade body 1 has sharp edge at 3 places substantially, this blade body is clipped between two thin hardboards 5 that are coupled, perhaps be embedded in the thin object 7 of duroplasts, and be positioned in the bottom 9 of narrow otch 11, also narrow therewith in addition otch is formed a sharp-pointed cutting angle.

Min-cutter body 7(or 5), that is the director element of min-cutter itself constitute by two sides 13 of narrow otch 11.

Owing to the bottom that blade body 1 is placed on narrow otch, so this narrow otch will form an effective protecting component to the cutting edge 3 of this min-cutter blade body 1.

According to this invention, Fig. 4 and Fig. 5 represent that min-cutter is applied in the cap of a pen end or the similar situation of other object end.

When requiring along object with flat surfaces, during as the cap of a pen and other article landscape configuration min-cutter, cutter hub 7 is installed to such an extent that have certain spacing apart from the end face 15 of the cap of a pen, nature, part 7 also be approach with subminiature, and be embedded with the blade body 1 of min-cutter, and the end face of the cap of a pen is arranged essentially parallel to the cutter hub 7 of min-cutter, can easily be inserted in the envelope that to open like this, otherwise will be difficult to insert.

Obviously, this invention is not limited only to disclosed this illustrated embodiment, and has several correction patterns and other corrective measure also can be applicable to the scope of this invention.

Claims
