Definitions

  • the invention relates to a writing or painting device, in particular a fiber pen, consisting of a barrel that absorbs the colored liquid and a closure cap that protects the writing or fiber tip and that can be removed from the barrel.
  • Writing and painting equipment such as ink pens, ink drawers, fiber pens, felt pens, text liners and the like. are known in the most varied of embodiments, these devices having a shaft for holding the ink, ink, paint or the like, e.g. in the form of refills or cartridges, and a cap covering the writing or fiber tip to protect against drying out is common.
  • the caps of these writing or painting devices are designed as screw or plug caps. In some writing or painting devices, the caps have dimensions that pose a choking risk for children if they are accidentally swallowed, or capsule pens because these caps or capsules get stuck under the larynx and block the trachea. Children tend to put caps or fountain pens in their mouths, suck or chew them, and accidentally swallow them. Such caps or capsules of writing or painting devices, such as fiber pens or the like, pose a choking risk for children if the caps or capsules are accidentally swallowed, and offer no security against suffocation.
  • the invention has for its object a writing or painting device, in particular a fiber pen, in which the writing or fiber tip is protected by a closure cap, so train that the risk of suffocation for children is reduced to a minimum if the cap is accidentally swallowed. Furthermore, the writing or fiber tip should be protected against drying out and the color of the writing or fiber tip should be recognizable in the area of the closure cap.
  • a fiber pen is provided with a cap, which provides a high level of security against suffocation if the cap is accidentally swallowed, especially by children. Due to the outer wall profile of the closure cap with outside air flow guide channels, which are connected to the inner air flow guide channel, which is formed by the interior of the closure cap, an inhalation and exhalation is ensured even after swallowing a safety cap designed according to the invention, since the and exhalation required air can flow through the swallowed safety cap, even if the swallowed sealing cap becomes lodged under the larynx and thus blocks the trachea.
  • a complete blocking, ie closing the trachea by a swallowed cap is no longer possible and the risk of suffocation is no longer there or is reduced to a minimum, because even if the cap is swallowed, an adequate air supply is always guaranteed.
  • the fact that the outer air flow guide channels lie between the web-shaped sections of the closure cap ensures that in ver swallowed cap, the air flow guide channels are not closed, because the web-shaped sections of the cap ensure that the air flow guide channels are kept clear.
  • the particular advantage of this sealing cap lies in particular in the fact that both internal ventilation and external ventilation are created through the openings and additionally through the air flow guide channels.
  • the fiber pen 50 shown as an exemplary embodiment in FIGS. 1, 2 and 9 is a writing or painting device that consists of a shaft 51 with an attached, removable and by means of a clamping fit on the shaft 51 of the fiber pen 50, there is a closure cap 10, the shaft 51 being designed to receive a colored liquid and carrying a fiber tip 52 at its upper end 12 (FIGS. 3 and 5), which will be discussed in more detail below Cap 10 can also be designed as a screw or plug cap. The lower open end of the cap 10 is designated 13. Both the closure cap 10 and the shaft 51 of the fiber painter 50 are made of plastics or other suitable materials.
  • the outer wall surface of the fiber painter shaft 51 is provided with a colored coating or the shaft 51 is made from a colored plastic, the color of the outer coating or the colored plastic then being the color of the colored liquid in corresponds to the interior of the fiber painter 50.
  • the closure cap 10 has an outer wall profile 20 which extends over part of the closure cap region and is formed in the outer wall surface 14 of the closure cap 10.
  • the unprofiled wall surface of the cap 10 is designated 14a and the interior of the cap 15 (Fig.10).
  • the closure cap 10 there is also the possibility of designing the closure cap 10 such that the outer wall profile 20 extends over the entire region of the closure cap.
  • This outer wall profile 20 comprises a number of outer air flow guide channels 121 which are distributed over the circumference of the closure cap and extend approximately in the longitudinal direction of the closure cap and which are arranged in the Cap wall 14 formed openings 30 are connected to the interior 15 of the cap 10, which forms the inner air flow duct 115 (Fig. 10 and 17)
  • the sealing cap outer wall profile 20 has a number of raised, web-shaped sections 22, which are distributed over the circumference of the sealing cap 10 and extend in the longitudinal direction of the sealing cap, and which end in the upper end 12 of the sealing cap 10 and with their lower ends 22c merge into the unprofiled wall surface 14a of the closure cap 10, the transition being able to be flush with the surface (FIGS. 17 and 18).
  • These web-shaped sections 22 of the sealing cap outer wall profile 20 run parallel to one another and are arranged at a distance from one another.
  • a groove-shaped or groove-shaped section 23 is formed between each two web-shaped sections 22 and, like the web-shaped sections 22, extends in the longitudinal direction of the closure cap.
  • the cross section of the web-shaped sections 22 of the closure cap 10 can be square, rectangular or triangular, but the cross sections can also have other geometrical shapes, so that those between the web-shaped Sections 22 formed groove-shaped sections 23 have a corresponding cross-sectional profile.
  • the web-shaped and the groove-shaped sections 22, 23 run in the longitudinal direction of the closure cap 21
  • the web-shaped sections 122 are designed to run helically, ie here there is an odd course, and an S-shaped course of the web-shaped and the groove-shaped sections 122, 123 can also take place.
  • the cap outer wall profile 20 can have a completely different shape, but it is always necessary that air flow channels are provided in the outer wall region of the cap 10 and are designed such that an air flow is guided in the longitudinal direction of the cap, the outer formed in the outer wall surface of the cap 10 Air flow guide channels 121 are connected to the interior 15 and the inner air flow guide channel 115 of the closure cap 10, be it through openings 30 formed in the groove-shaped sections 23 or 123 of the closure cap outer wall profile 20 or through a plurality of openings 30 in each individual groove-shaped section 23 or 123.
  • the openings 30 are ring-shaped in the groove-shaped sections 23 and 123 adjacent to the transition region of the web-shaped sections 22 of the sealing cap outer wall profile 20 into the non-profiled wall surface 14a of the sealing cap 10 and have, depending on the cross-sectional profile of the web-shaped sections 22 and 122 and the groove-shaped sections 23 or 123 a correspondingly designed opening area (Fig. 17 and 18).
  • the air flow area of each opening 30 corresponds approximately to the shape of a square, a rectangle or a trapezoid.
  • the openings 30 are laterally limited the web-shaped sections 22 and 122 of the outer wall profile 20 of the closure cap 10.
  • the openings 30 should have the largest possible dimensions in order to ensure that large amounts of air can flow through.
  • each web-shaped section 22 or 122 of the sealing cap outer wall profile 20 preferably corresponds to a multiple of the wall thickness of the sealing cap 10.
  • the spacing of the web-shaped sections 22 or 122 from one another can be of the same or different design.
  • the number of the outer air flow guide channels 121 of the sealing cap outer wall profile 20 can be chosen arbitrarily; it will depend in each case on the diameter and the dimensions of the closure cap 10.
  • the cap 10 according to Fig. 11 and 12 has ten
  • the cap according to Fig. 13 and 14 has twelve
  • the cap according to. 15 and 16 have eighteen outer air flow guide channels 121, which results in the corresponding number of openings 30, so that caps 10 with a plurality of small openings 30 and caps 10 with only a few openings 30 are created, in which case the latter Openings have relatively large dimensions.
  • an inner cap 16 is arranged in the interior of the closure cap 10 or an interior profile configuration is provided, which is formed at the same time during the manufacture of the closure cap 10 with its closure cap outer wall profile 20.
  • the closure cap 10 with its closure cap outer wall profile 20 and this inner cap 16 or with the interior profile configuration, which will be discussed in more detail below, are formed in one piece or are formed in the manufacture of the closure cap 10.
  • This inner cap 16 encloses the fiber tip 52 of the fiber pen 50 in an airtight manner, thus preventing the fiber tip from drying out and contributing to a firm fit of the closure cap 10 on the fiber pen shaft 51.
  • the openings 30 are formed in the groove-shaped sections 23 and 123 of the cap outer wall profile 20 below the inner cap 16 in the groove-shaped sections 23 and 123, so that, in addition, a securing of the writing - And painting equipment against drying out is given without the air flowing through the cap 10, if it should be swallowed, is reduced.
  • the free end 51a of the shaft 51 carrying the fiber tips 52 has an outer wall profile and the interior of the cap has a corresponding interior design or Inner wall profiling on (Fig. 2,5,6,7 and 8).
  • the shaft 51 of the fiber painter 50 is provided with a first retracted, cylindrical portion 151 at its end 51a carrying the fiber tip 52, forming a first step-shaped section 150.
  • This section 151 merges into a second section 152, which tapers conically to the fiber tip 52, to which a third, drawn-in, cylindrical section 154 connects to form a second step-shaped section 153.
  • This section 154 carries at its free end 154a the fiber tip 52, the diameter of which is smaller than the diameter of the section 154, so that a third step-shaped section 155 is formed (FIGS. 1, 3, 5 and 6).
  • the cap 10 has an interior configuration corresponding to the profiled end of the fiber paint shaft 51 (FIGS. 7 and 8).
  • the inner cap 16 or that molded part of the closure cap 10 which receives the shaft 51 with its end section carrying the fiber tip 52 has a first inner wall section 160 which corresponds to the shape, the profile and the dimensions of the shaft 51.
  • This inner wall section 162 merges into a third inner wall section 163 located in the area of the openings 30 formed in the closure cap 10 and arranged in a ring shape Dimensions correspond to those of the tapered shaft section 152.
  • a fourth inner wall section 165 adjoins the inner wall section 163 to form a step-shaped section 164, the cylindrical shape of which corresponds to the cylindrical shaft section 154, the dimensions of the shape of the inner wall section 165 corresponding to those of the shaft section 154.
  • the inner wall section 165 merges with the formation of a step-shaped section 167 into a fifth inner wall section 166 which, like the inner wall sections 160, 162 and 165, is hollow-cylindrical, the inner wall section 166 being designed such that the fiber tip 52 comes to lie in the interior of the inner wall section 166.
  • the inner wall sections 160, 162, 163, 165 and 166 are formed as lined-up cylindrical hollow bodies which are designed in terms of their dimensions and their shapes so that the fiber-paint shaft 51 with its profiled end section when the closure cap 10 is attached with its individual cylindrical sections 151, 154 including the cylindrical section of the shaft 51 which is followed by the cylindrical sections tapering to the fiber tip 52, and the frustoconical section 152 comes to lie in the corresponding recesses or inner wall section of the closure cap 10, which is designed as cylindrical sections, as shown in FIG.
  • the web-shaped sections 22, 122 run with their inner edges in the area of the openings 30 in accordance with the outer shape of the section 152 of the fiber-paint shaft 51 (FIG. 8). Since the shaft 51 with its shaft sections 151, 152 comes to lie in the closure cap 10 in the area of these openings 30, the color of the shaft 51 can be seen through the openings 30.
  • a fiber pen with a sealing cap has been created which, due to its valve-like properties, makes a significant contribution to reducing the risk of suffocation when the sealing cap is swallowed and which, moreover, ensures an interior profile of the sealing cap which is oriented towards the outer profiling of the fiber pen shaft to ensure a high level of security against If the fiber pen dries out after a long period of non-use, the closure cap on the fiber pen shaft is well clamped.
  • the profile 20 can be formed in the outer wall of the closure cap; however, it is also possible to design the cap wall itself with a corresponding profile 20.
  • the formation of the web-shaped sections 22, 122 can also take place in that, if the closure cap 10 has a correspondingly thick wall, 14 grooves or grooves are formed in the closure cap wall, which then form the air flow guide channels 121, which then open into the openings 30 which are also provided.
  • the openings 30 formed in the closure cap 10 simultaneously represent windows in order to make the color of the shaft recognizable through them from the outside when the closure cap 10 is placed on the shaft if the color of the shaft corresponds to the color liquid. This is possible because, when the closure cap 10 is in the plugged-on state, the portion carrying the writing or fiber tip comes to rest in the area of the openings 30.
  • the inner cap 16 of the closure cap 10 covering the writing or fiber tip 52 of the writing or painting device 50 can be made of a crystal-clear material in the area of the groove-shaped sections 23 and 123, respectively that the color of the writing or fiber tip is recognizable from the outside.
  • This window-like configuration can e.g. can be obtained in such a way that the closure cap 10 is made of crystal-clear materials and then colored to form window-like viewing openings.
  • the cross section of the shaft of the color painter 50 need not be circular. Other cross-sectional shapes are also possible.
  • the outer wall profiling of the shaft is then formed at its end carrying the fiber tip in accordance with the previously described gradation.
  • the inner wall sections or cylindrical cavities of the closure cap are then adapted to the respective cross-sectional shapes of the shaft or its gradation at the free end.
