Definitions
- the present invention concerns a so-called fibre-tip pen, that is a writing instrument wherein the ink reservoir and the nib consist of fibrous elements.
- the commercially available pens of such kind comprise, beside the nib and the reservoir, at least three elements made of plastics, namely a body, a closing bottom and a cap (if the nib is directly inserted into the body), or a body closed at one end, a nib-holder and a cap.
- the aim of the invention is to provide a pen with a very simple structure, comprising a number of pieces of plastics reduced to a minimum.
- a pen that comprises, besides the nib and the reservoir, only two elements of plastics, namely a body closed at one end and a cap.
- the fibre-tip pen comprises a body 1 of plastic material, consisting of a tubular element 1a closed at one end by a base 1b which is integral with tubular element 1a.
- Body 1 houses inside it a reservoir 3, consisting of a fibrous tubular element impregnated with ink, and has, at its end opposite to base 1b, an opening arranged to receive a portion 4a of a nib 4, which portion is opposite to tip 4b.
- a reservoir 3 consisting of a fibrous tubular element impregnated with ink, and has, at its end opposite to base 1b, an opening arranged to receive a portion 4a of a nib 4, which portion is opposite to tip 4b.
- nib 4 made of a fibrous material, is directly inserted into pen body 1.
- the nib comprises a first portion 4a, with such a diameter as to be fitted under pressure into body 1, and a second portion 4b, generally sharpened or rounded, which remains outside body 1 and which will therefore be used for writing.
- the inner nib portion 4a is in contact with fibrous element 3 impregnated with ink, as shown in the drawing, so as to transfer the ink from reservoir 3 to nib tip 4b.
- the diameter of the outer nib portion 4b may be the same as that of inner portion 4a, for simplicity of manufacture, or it may be smaller or greater, the latter solution being shown in the drawing.
- the diameter of inner portion 4a decreases, because of the pressure exerted by the internal walls of body 1.
- a cap 5 made of plastics is then applied on the end portion of body 1 and on nib 4, which cap is arranged to protect the nib and to prevent the ink in the reservoir from becoming dry.
- body 1 and cap 5 are the only “non-inked” elements, made of plastics in this embodiment, necessary for the pen manufacture.
- plastics like the nib-holder and/or the body-closing bottom, present in all commercially available pens, so that the production costs are reduced and the pen assembling operations are simpler.
Abstract
Description
- The present invention concerns a so-called fibre-tip pen, that is a writing instrument wherein the ink reservoir and the nib consist of fibrous elements.
- In the simplest case, the commercially available pens of such kind comprise, beside the nib and the reservoir, at least three elements made of plastics, namely a body, a closing bottom and a cap (if the nib is directly inserted into the body), or a body closed at one end, a nib-holder and a cap.
- The structure of such pens, even though very simple, entails therefore the manufacture of three pieces made of plastics, two of which, the body and the closing bottom or the body and the nib-holder, must be made with particular care, to avoid possible ink leakage.
- The aim of the invention is to provide a pen with a very simple structure, comprising a number of pieces of plastics reduced to a minimum.
- This aim is attained by a pen that comprises, besides the nib and the reservoir, only two elements of plastics, namely a body closed at one end and a cap.
- It is evident that eliminating one of the elements of plastics reduces the production costs and simplifies the pen assembling operations.
- The above and other aims are attained by the pen made in accordance with the invention, as claimed in the appended claims.
- The above and other aims of the invention will become more apparent from the description of a preferred embodiment, with reference to the accompanying drawing which shows, in cross-sectional view, a pen made in accordance with the present invention,
- As shown in the drawing, the fibre-tip pen according to the invention comprises a
body 1 of plastic material, consisting of atubular element 1a closed at one end by a base 1b which is integral withtubular element 1a. -
Body 1 houses inside it areservoir 3, consisting of a fibrous tubular element impregnated with ink, and has, at its end opposite to base 1b, an opening arranged to receive a portion 4a of anib 4, which portion is opposite to tip 4b. - In
effect nib 4, made of a fibrous material, is directly inserted intopen body 1. The nib comprises a first portion 4a, with such a diameter as to be fitted under pressure intobody 1, and asecond portion 4b, generally sharpened or rounded, which remains outsidebody 1 and which will therefore be used for writing. Generally, the inner nib portion 4a is in contact withfibrous element 3 impregnated with ink, as shown in the drawing, so as to transfer the ink fromreservoir 3 tonib tip 4b. The diameter of theouter nib portion 4b may be the same as that of inner portion 4a, for simplicity of manufacture, or it may be smaller or greater, the latter solution being shown in the drawing. However, during insertion ofnib 4 intobody 1, the diameter of inner portion 4a decreases, because of the pressure exerted by the internal walls ofbody 1. - A
cap 5 made of plastics is then applied on the end portion ofbody 1 and onnib 4, which cap is arranged to protect the nib and to prevent the ink in the reservoir from becoming dry. - In the structure described above, which forms the subject matter of the invention,
body 1 andcap 5 are the only "non-inked" elements, made of plastics in this embodiment, necessary for the pen manufacture. Thus it is possible to eliminate some elements of plastics, like the nib-holder and/or the body-closing bottom, present in all commercially available pens, so that the production costs are reduced and the pen assembling operations are simpler.
Claims (4)
- Writing instrument of the type comprising a body (1) internally housing an ink reservoir (3) made of fibrous material, a nib (4) co-operating with said reservoir (3) and a cap (5) which can be applied on said body to protect said nib (4), characterised in that said body (1) is made of a single piece and comprises a tubular element (1a), which is closed at one end by a base (1b) and which presents, at the opposite end, an opening for the introduction of a nib (4).
- Writing instrument according to claim 1, wherein said nib (4) comprises afirst portion (4a), arranged to be introduced into the opening of said body (1), and a second portion (4b), which remains outside the body (1) and which is used for writing.
- Writing instrument according to claim 1, wherein said body (1) is made of plastics.
- Writing instrument according to any preceding claim, further comprising a removable cap (5), which can be applied onto the end portion of said body housing the nib (4) and which is arranged to protect the nib (4) and to prevent the ink from becoming dry.
