Definitions

  • the invention relates to a closure cap for writing or similar devices in the form of a sleeve, with an interior and an insert opening that can be closed by the writing device, and an air duct that extends in the axial direction of the sleeve.
  • Caps of this type have different functions to perform.
  • the main thing is to cover or seal a writing tip.
  • the latter is particularly the case with writing implements which are filled with liquid and volatile recording liquids.
  • Another important important function, according to recent knowledge, is seen in the fact that the cap must provide an air passage in the axial direction if, owing to its relatively small dimensions, it is taken into the mouth by a living being and from there into the trachea. In this case, the risk of suffocation must be excluded. an air passage cross-section must be kept which is sufficiently dimensioned to allow further ventilation.
  • Air passages on caps that fulfill this purpose are known for example from GB 21 74 734.
  • a plurality of axial, radially outwardly open channels are provided which lead into the interior of the cap in the region of the insertion opening.
  • the depth and width of the channels is very limited because the outer diameter of the cap is not significantly larger than that of the writing instrument shaft. It cannot therefore be ruled out that within the trachea both the channels and the ribs separating them are enclosed by the elastic tissues inside or in particular at the beginning of the trachea and therefore prevent or restrict air passage.
  • the cross section of the air duct itself is limited by the fact that the sealing caps of the writing implements have to be kept as small as possible in cross section so that they do not take up too much space in the cases. In most cases, writing utensils of this type are included in the case in different colors. Therefore, if possible, the cross section of the caps is designed so that the total space requirement is not increased by the caps, but an arrangement is made possible in which the shafts of the writing instrument lie against one another.
  • the invention is therefore based on the object of providing a sealing cap with at least one large-volume air duct which makes it possible to arrange a plurality of writing instrument shafts in a case lying directly against one another.
  • a non-closed air duct is formed by two strips.
  • the cross section of the air duct can be designed to be extraordinarily voluminous, it being possible at the same time to line up the writing instrument shafts, since the strips enclose the sleeve of the writing instrument arranged next to it in the form of holding claws. This ensures not only sufficient air passage, but at the same time a minimal space requirement for several writing utensils, which can be accommodated next to each other in a case.
  • the circumference of the closure cap can be enlarged by the strips to such an extent that penetration into the trachea is prevented.
  • a particular advantage is seen in connecting the writing utensils together using the sleeves, so that at least two writing utensils can be plugged together to form a unit. This can be achieved if the strips are resilient and their free ends are at a distance which is smaller than the thickness of the device shaft.
  • this is particularly useful when the application tip is in the form of a wedge surface, which must be guided accordingly when using the writing instrument. According to the features of claim 11, this can be achieved by arranging a locking groove in relation to the position of the wedge surface at the tip of the application.
  • the cap can not only be attached to the device shaft, but also to a similar closure cap. This can be achieved in a simple manner with an arrangement of the connections of the strips according to the features of claim 6. Good conditions for injection molding and a secure positive fit of sleeves put together or of sleeves with device shafts are therefore achieved with an embodiment which makes use of the features of claim 7.
  • the strips are part of an essentially U-shaped holding claw, which forms a separate part and which consists of opposing pairs of concave and convex arches, the inner radius of the convex arch corresponds to the outer radius of the device shaft.
  • a rationalization effect in the manufacture of the writing instrument is achieved by a separate holding claw, in which the strips are formed by the u-shaped legs of the claw. In this way, the sleeve can be made in the same color as the device shaft and only the holding claws in different colors need to be attached to the corresponding strips. It is also possible to manufacture the cap and holding claws from different materials, for example from metal.
  • a positional orientation in the axial direction without additional space requirement is achieved by a U-shaped holding claw, which has an outer diameter at the base that is smaller than the outer diameter of the sleeve and that a recess is provided in the sleeve.
  • the sleeve is also useful for improving the ergonomics of the grip area of the writing instrument if the end face which contains the insertion opening is designed as an inclined surface.
  • the device shaft contains at least one locking groove on the outer circumference at right angles to a wedge surface of the application tip, which corresponds to a knob on the inside of one of the strips.
  • Figures 1 and 2 show the essence of the novel cap.
  • This consists of a sleeve 1, which is open on one end to receive a device shaft 2 with an application tip 3, which is sealed within a sealing neck 6 in a known manner.
  • FIG Sleeves 1 are inserted into each other. Since the outer diameter of the sleeve 1 is identical to the outer diameter of the device shaft 2, both a sleeve 1 can be pushed onto a sleeve 1 of the same type as a device shaft 2 (see FIGS. 5 and 6).
  • FIGS. 3 and 4 show a further exemplary embodiment of the invention, in which the strips 8 are designed as a holding claw which can be produced separately.
  • a recess 11 is provided for fastening this claw to the sleeve 1, as a result of which the strips 8 can be oriented in their axial position.
  • the holding claw is also formed.
  • This claw is inserted into a recess 11 of the sleeve 1, the ends of which have the function of the strips 8 according to the exemplary embodiment in FIG.
  • the claw can be made of both plastic and metal and can be produced in different colors when used on writing implements.
  • the color difference can be achieved through the sleeve 1.
  • the claw mentioned is resilient in the recess 11 of the sleeve 1 and has two legs, which are composed of a concave 12 and convex 13-shaped arch. It is also possible here that the free ends 9 of the claw grip a second claw in a non-positive and positive manner.
  • a further advantage can be achieved according to an embodiment according to FIG. 7 if the sleeve 1 has an inclined surface 14 and a knob 10 is formed in the area of the strips 8.
  • the knob 10 engages in a locking groove 15, as a result of which the wedge surface 4 of the application tip 3 can be aligned in accordance with the sleeve 1.
  • an enlarged grip zone is created which no longer requires alignment of the application tip 3. It is useful in this embodiment to provide an inclined surface 14 which is largely adapted to the finger position when writing and thus takes into account the laws of ergonomics.
