Definitions
- the invention relates to a pen with a mine and a mine surrounding Mine envelope. Under mine cover all parts of the pen are understood, permanently or temporarily adjacent to the mine, eg. Legs the mine coaxially enveloping sleeve and an optional to protect the pen tip on this attachable cap.
- Such a pen for applying Color used on paper or similar sheet materials.
- Such a pen may in turn, e.g. at a Kajal or lipstick, to apply color to the skin.
- a lipstick may be the use of the pen, such as a lipstick, too to order a cosmetic or pharmaceutical preparation.
- pollution to be cleaned is therefore in this context on the one hand a macroscopic contamination by granular, lubricating or liquid material, such as Dust, earth, skin particles or hair called.
- granular, lubricating or liquid material such as Dust, earth, skin particles or hair called.
- a such contamination is extremely noticeable e.g. in the infestation of the pen tip by bacteria, Viruses, mites or fungi.
- the invention is therefore an object of the invention to provide a pen for Use in the medical or pharmaceutical field is suitable.
- the cleaning agent is a passive cleaning Material.
- a passively cleansing substance is a substance that generally Meaning a pollution-repellent effect.
- Well known are substances, which are primarily repellent to macroscopic pollution. This is especially intended to a so-called anti-stick surface, such as they e.g. used with kitchen utensils with great success.
- Such Anti-adhesive surface prevents by means of a smooth, dense surface structure, chemical inertness and thus a very low coefficient of friction, that macroscopic contamination can adhere to the surface.
- An in Particularly advantageous material in this regard is polytetrafluoroethylene (PTFE).
- PTFE is a chemically and biologically inert and hydrophobic plastic that is commercially available under the trade name Teflon®.
- Teflon® a PTFE coating
- the non-wetting effect of a surface is mainly below the Term "lotus effect" known. This property manifests itself in the fact that liquids, especially water, can not adhere to the surface, but roll off.
- the lotus effect is achieved by a surface that is microscopic Fine structure, e.g. in the form of small nubs. Water and others Soiling touches the surface only in the area of the stud ends, So only in a very small area, and therefore can not cling to the surface.
- a general advantage of a passive cleaning form is that in the intended Use of the pen no toxic or irritant substance is released.
- the pen thus has a particularly high compatibility, especially for allergy sufferers, on.
- the cleaning agent in addition or alternatively to a passive cleaning action, an active cleaning action.
- active cleaning action include, in particular with regard to microbial contamination chemical killing or decomposition of germs or fungi understood.
- a plastic for the mine cover advantageous in itself antimicrobial acts. Such plastics may e.g. out with a disinfectant be made offset polymer.
- the cleaning agent to integrate in the mine envelope. So it is for example when using a cleaning agent with an undesirable side effect appropriate, the cleaning agent as a permanent component, in the form of a coating the mine cover or distributed throughout the volume of the mine cover. In this way, although an accumulation of pollution in the vicinity the mine prevents. On the other hand, the cleaning agent does not get into the lead material itself, and therefore not on the skin.
- the detergent As a component of the shell material.
- the shell material which in gaseous or liquid form over long Time slowly exits the mine cover.
- the cleaning agent is during the storage of the pen permanently held in the mine cover, and only occurs Mechanical stress of the mine cover from the shell material. This is particularly advantageous when the triggering of the cleaning agent mechanical stress on the mine cover when used as intended of the pen, e.g. at-tips of the pen or during a relative movement the mine opposite the mine cover, occurs.
- the cleaning agent is in this Drop only when the pen is used. Through the targeted Output of the cleaning agent this is used particularly economically, especially as the cleaning agent is not consumed during the storage times. On the other hand, there is always a thorough cleaning of the pen tip, when the pen is used.
- This principle is realized in particular by a a mine envelope containing a microporous carrier, wherein the detergent is absorbed in the pores of the carrier. Especially if the pores the carrier is closed, is a loss or aging in the Pores trapped detergent effectively inhibited. Only when the pen is tipped before use, the pores are cut, causing the detergent exit and wet the pen tip cleansing. This cleaning can be done both actively done by killing germs, as well as passively, by the cleaner a dirt-repellent film over the Pen point forms.
- the pencil is in the manner of a pencil fixedly connected to a mine-like surrounding part of the mine cover.
- the sleeve is preferably made of a wood composite or a Made of plastic.
- Such a pen can be particularly good point, as the Sleeve that supports and protects mine.
- tips is advantageously the peeled off due to storage and use soiled old surface of the pen tip.
- the cleaning agent serves primarily to prevent new pollution the exposed surface by the pointed tool or the Skin contact.
- the mine slidably with respect to the sleeve.
- This embodiment is preferably used in a very soft and wide mine use.
- one of a lipstick itself provided known rotary drive of the mine.
- the pin in analogy to a mechanical pencil with a To equip pressure drive for mine feed. This version has in particular the advantage that the pen is providable with a replaceable mine.
- a pin provided with one or more of the features described is especially suitable for a mine, a medical or pharmaceutical Contains active ingredient, especially since the integrally provided detergent the required hygienic boundary conditions without special external intervention.
- the described Cleaning agent preferably used in combination with each other and, if necessary, also used in spatially different place. That's the way it is appropriate to build the mine cover from several layers, whose outer, for example, has a passive cleaning effect, and their inner serves for active cleaning of the mine.
- the cap would be conceivable and equip the sleeve with various cleaning agents. It continues possible to design a pressure drive for the mine in such a way that it does with the mine advance simultaneously mechanically stressed the sleeve material, whereby At the same time, a targeted discharge of the cleaning agent takes place during the lead feed.
- Fig. 1 shows a schematic cross-section of a pharmaceutical or pen 1 provided for medical use.
- the pen 1 comprises a refill 2, which is surrounded substantially coaxially by a sleeve 3.
- the mine 2 and the sleeve 3 stationary connected to each other.
- a longitudinal end of the pin 1 to a pen tip 4 conically tapered.
- the near-axis region of the penpoint tip 4, in which the Mine 2, the sleeve 3 projects beyond and in which the mine 2 thus at the pin surface is merely, is designated as a writing surface 5.
- the pin 1 is coated on the outside by a protective lacquer layer 6.
- a cap 7 on the Pen tip 4 attached.
- the inner wall 8 of the cap 7 is substantially formed complementary to the pen tip 4. In the area of the opening 9 of the cap 7 this is provided with a seated on the sleeve 3 seated rim 10, to ensure the captivity of the cap 7 during storage and to enclose the pen tip 4 substantially airtight.
- the illustrated pen 1 is preferred to medical and pharmaceutical Intended purpose.
- the pressed powdery form or paste-like form Mine 2 present is therefore with a medical or pharmaceutical Provided drug, which is analogous to the use of a normal pencil by pressing the writing surface 5 on the skin of a subject, not shown is orderable.
- the sleeve 3 provided with a cleaning agent 11, which in a sketchy detail view is shown in Fig. 2.
- the material of the sleeve 3 then comprises a microporous Carrier 12, in the pores 13 of the cleaning agent 11 was added is.
- the pin 1 should be freshly sharpened before use.
- The are in the Cutting surface lying pores 13 of a cutting tool, not shown cut.
- the contained in these pores 13 liquid or paste-like Cleaning agent 11 occurs during the sharpening process from the trimmed Pore 13 and forms on the surface 14 of the pen tip 4 is a thin Movie 15 off.
- the detergent 11 contains an antibacterial, antiviral or fungicidal active ingredient and cleanses by killing germs or
- the film 15 evaporates immediately during the sharpening process, so that at the time of using the Pen 1 the surface 14 disinfected, but mainly of residues of the cleaning agent 11 is free.
- the resist layer 6 shown in Fig. 1 is preferably impermeable as well towards the cleaning agent 11 as well as against penetrating water and against other contaminants.
- the protective lacquer layer 6 protects the sleeve 3 on the one hand from contamination.
- the protective lacquer layer inhibits 6 the evaporation of the cleaning agent 11 to the outside.
- the inner wall 8 of the cap 7 is preferably with a non-wetting surface Mistake. Such a non-wetting surface is e.g. from nature known from the leaf of the lotus flower.
- the inner wall 8 is enlarged schematically shown in Fig. 3. Thereafter, the inner wall 8 for the production of the so-called "Lotus effect" provided with microscopic nubs 16, the prevent accumulation of water and dirt.
- FIG. 4 an alternative embodiment of the pin 1 is shown, in which the Mine 2 in the manner of a lipstick in the longitudinal direction 17 of the pin 1 opposite the sleeve 3 is slidably disposed.
- the sleeve 3 is in this embodiment integrally formed on a knob 18.
- the knob 18 is in one Ring groove 19 on a cylindrical outer wall 20 of the pin 1 about the pin axis 21 rotatably mounted.
- the mine 2 is facing the knob 18 at its End 22 mounted on a carriage 23, which prefers as part of the mine cover at least partially made of PTFE (Teflon).
- the carriage 23 engages with two relative to the pin axis 21 radial formations 24 by one helically around the sleeve 3 winding slot therethrough in each case a longitudinally extending 17 groove 25 of the outer wall 20 a.
- the sleeve 3 contains in the embodiment shown in FIG. 4 a migrating Detergent 11, that is, a substance that is gradually removed from the material diffused out of the sleeve 3.
- the outer wall 20 is one for the cleaning agent 11 impermeable material produced and inhibited in this way the unused Loss of the cleaning agent 11 through the outer wall 20th
