Definitions

  • the invention relates generally to an improvement to caps for writing instruments containing ink and in particular to a cap with a safety ventilation device in order to facilitate an air flow along the cap, if the latter has lodged in a person's windpipe, for example of a child, when swallowed accidentally.
  • a cap for a writing instrument containing ink having safety ventilation means enabling an air flow along the cap, if the cap has lodged in a person's windpipe when swallowed accidentally, said cap being closed on all sides with the exception of an insertion end, said safety ventilation means comprising at least one axial ventilation path on the outside of the cap, which along at least part of its axial extension has an open cross-sectional configuration, whereby when a covering is placed around the cap, a cross-sectionl area for ventilation in each radial plane is defined having a throughflow capacity corresponding to the air requirement of a person, said ventilation path comprising a space between a substantially plate-like retaining clip and the outer surface of the cap, said retaining clip being attached adjacent the closed axial end to the cap, in which the spring deflection of said clip being limited by a stop for maintaining a minimum spacing with respect to the cap, said clip in its base portion has a perforation aligned substantially axially to and communicating with said space between the cap
  • the resilient connecting webs in the base portion also contribute to preventing injuries to the windpipe or gullet.
  • a feature of the caps according to the present invention is the high sealing function resulting from the fact that the caps are closed on all sides, i.e. there are no perforations leading into the inside of the caps.
  • the caps therefore corresponds in their sealing function to conventional caps used in writing instruments without a safety ventilation device.
  • Existing caps can therefore readily be replaced by safety caps according to the invention.
  • the construction of the safety ventilation device according to the invention has advantages both as regards manufacturing techniques, since it is not necessary to form any cavities which are not easily accessible, as well as an improved safety function, in that the portions of the caps, which are critical, can readily be checked at a glance as regards their functional state.
  • a further advantage is the relatively high freedom as regards the design of the caps.
  • the cap bears the general reference numeral 1.
  • the cap 1 has a substantially tubular or cylindrical shape with an outer diameter of normally up to 16 mm.
  • the cap is closed at one axial end, whereas the other axial end is provided with an insertion opening 4.
  • the writing part 9 of the writing instrument 8 supporting the writing point 10 is inserted by way of the insertion opening 4.
  • a retaining clip 2 extending coaxially to the cap 1 is attached by its base region 12 to the closed top of the cap 1.
  • the base region 12 may be curved and contains a perforation 3 aligned substantially axially.
  • the airway of the present embodiment comprises the perforation 3 and the gap 6 connected thereto between the retaining clip 2 and the outer surface of the cap 1.
  • the airway should have a cross-sectional area of at least 3.4 mm 2 , preferably greater equal to 6.8 mm 2 , at any axial point along the cap.
  • the retaining clip 2 extends along the outside of the cap 1 as far as a point close to the insertion opening 4. In order that an adequate airway is guaranteed between the edge of the insertion opening 4 and the free end of the retaining clip 2, the spacing m of the free axial end of the retaining clip 2 from the insertion opening 4 should amount to less than 2 mm.
  • the reference numeral 5 relates to the inside of the cap, which when the writing part 9 is inserted, is sealed with respect to the atmosphere by a peripheral region of the writing instrument 8.
  • the reference numerals 13 relate to web-like areas, which are formed by the perforation 3 provided in the base attachment region 12 of the retaining clip 2 and which connect the retaining clip 2 resiliently to the cap.
  • the cap 1 with the inserted writing instrument 8 can be clipped to an article of clothing by means of the retaining clip 2.
  • the perforation 3 in the base attachment region 12 and the gap 6 between the retaining clip 2 and outer surface of the cap 1 form an airway, so that the air passage necessary for the child to breathe is ensured and the danger of asphyxiation does not exist. Furthermore, since the retaining clip extends close up to the insertion opening 4 of the cap, even close to this end of the cap, the airway is not closed by the windpipe. Since the retaining clip is held resiliently by the connecting webs 13, even in the case of contact of the tip of the retaining clip 2 with the gullet or windpipe, the danger of asphyxiation is substantially reduced.
  • the reference numeral 7 relates to a projection, which keeps the retaining clip at a suitable distance from the surface of the cap 1.
  • the second embodiment of the invention is illustrated in Figures 5 to 8.
  • the difference from the embodiment according to Figures 1 to 4 consists in that the retaining clip 2 is attached by way of a radial base attachment region 12 to the top of the cap 1.
  • the retaining clip 2 extends along the cap 1.
  • an axial perforation 3 Provided in the attachment base region 12 of the retaining clip 2 is an axial perforation 3, which is in axial alignment with the gap 6 between the retaining clip 2 and outer side of the cap, so that an airway is formed, which extends as far as the insertion opening 4 of the cap 1.
  • resilient connecting webs 13 are formed in the base attachment region 12 of the retaining clip 2 on both sides of the perforation 3, which connecting webs facilitate clipping of the cap to air article of clothing and at the same time alleviate the danger of injury to the windpipe, if the cap is accidentally swallowed.
  • the third embodiment of the invention is illustrated in Figures 9 to 12.
  • This embodiment differs from the embodiment according to Figures 5 to 8 substantially solely in that between the gap 6 and the perforation 3 in the base attachment region 12, an enlarged air space 14 is provided at the top of the cap 1.
  • the perforation 3 can consequently be offset somewhat radially with respect to the gap 6.
  • the resilient connecting webs 13 are provided in the base region 12 at the sides of the perforation 3.
