Definitions

  • the invention relates to a cap for writing instruments, in particular for ballpoint pens, but also for other writing, drawing or painting instruments, the cap having at least one air channel penetrating the end face.
  • Such caps are known from EP-OS 204 252 (AI). However, these known caps always consist of several inserted and / or axially movable parts and are therefore always expensive and usually complicated to manufacture.
  • the object of the invention is therefore to provide a simple and inexpensive to produce cap for writing utensils of all kinds, which reliably protects both against soiling of clothing and against damage to the writing tip and which nevertheless enables continuous air circulation when it is not connected to the writing instrument .
  • Fig. 1 shows a first embodiment in part according. the line A-A in Fig. 3 sectional view
  • Fig. 2 is a side view of the cap acc. Fig. 1
  • Fig. 3 is a plan view of the cap acc. 1 and 2
  • FIG. 4 shows a second embodiment in a sectional view along the line B-B in FIG. 6,
  • Fig. 5 is a side view of the cap acc. Fig. 4,
  • Fig. 6 is a plan view of the cap acc. 4 and 5 and
  • Fig. 7 shows a third variant with integrated inner seal in a sectional view.
  • the cap 1 shown in FIGS. 1 to 3 is formed in one piece overall and has an integrally formed clip 10.
  • the closed end face 2 is provided with two semicircular, axially extending sections 4 ′ of a continuous air duct 4 that break through the end wall 3.
  • a disk 5 'held by webs forms as an impact wall 5 acting from the inside.
  • a ring-shaped circumferential step 5 ′′ serving as a transverse baffle 5 in this case causes a deflection of the air flow and reliable protection of the writing tip 11 — which here contains a writing ball 12 — from damage by foreign bodies penetrating axially into the cap 1. It also prevents z.
  • fabric parts of a garment penetrate far into the cap and can come into contact with the writing tip 11 or writing ball 12 and contaminate them.
  • the shaft 14 of the writing instrument and the cap 4 are connected to one another in a form-fitting or friction-locked manner, but axially releasably.
  • the substantially axially and radially offset axial sections 4 'and 4' 'of the air duct 4 and the axially adjacent steps 5' 'and / or disks 5' serving as baffle walls 5 are advantageously designed such that they are essentially the same or have approximately the same cross section. This facilitates or enables the axial demolding of the caps, which are generally made of thermoplastic material by injection molding. To secure or secure the washers 5 'serving as impact walls 5', these are connected to the end wall 3 and / or the cap wall 8 via radial and possibly also axially extending webs 6.
  • a first axially extending section 4 'of an air duct 4 arranged coaxially to the interior 7 of the cap 1' penetrates the end wall 3 from the end face 2.
  • a continuous air channel 4 is created via radial openings 4 ′′ ′′ and further axial sections 4 ′′.
  • the cap 1 ' which has a clip 10, is fitted onto the shaft 14 of a writing instrument likewise provided with a writing ball 12. For the axial covering of the writing tip 11, one is used as
  • Baffle 5 designed round disc 5 ', which has practically the same cross-section or the same diameter, like the axially adjoining section 4 'of the air duct 4.
  • This disk 5' is firmly connected by webs 6 to the cap wall 8 or to the end wall 3 or is integrally formed thereon.
  • the number of webs 6 can be chosen arbitrarily. For example, two, three or even four webs are advantageous and sufficient.
  • the cap 1 ′′ in principle as shown and described in FIGS. 4 to 6, is assigned to a writing, drawing or painting device with a wick tip 13 and is provided with an additional seal 9. Characterized the wick tip 13 and possibly existing in the area of the writing tip 11 '' air openings of the writing instrument in the closed position, i. that is, airtight when the mounting position is pushed onto the shaft 14 and held positively with the annular bead 15.
  • the seal 9 is cup-shaped here and integrally formed on the baffle 5 or on the disc 5 'held by webs 6'. Alternatively, any other seal shape and type can be selected. So z. 3. a foam or foam rubber cushion or a silicone overlay or insert can also be used as the seal 9.
  • cap 1, 1 ', 1' 'to allow air to flow axially from the inside and outside, if it is not connected to the writing, drawing or painting device, is intended in particular to ensure the safety of children or other people reduce the risk of suffocation if such a cap is swallowed.
  • the secure connection between the shaft 14 and the cap 1 is achieved by means of an annular groove 16 in the shaft 14 and an annular bead 15 on the cap 1".
  • the recessed disc 5' also offers the possibility of advantageously arranging a product, company or other identification in a protected manner. Blurring or damaging a mark made there is practically impossible. Positions
  • Air duct general or overall

Abstract

Un capuchon pour instruments d'écriture, notamment pour stylos à bille, comporte au moins un canal d'air (4) qui traverse la face frontale (2). Ce canal d'air est disposé axialement et radialement et se trouve dans la région de la face frontale fermée par ailleurs. Les sections (4') disposées axialement du canal d'air sont délimitées par au moins une paroi transversale d'impact (5) ou bien par au moins un étagement (5'') ou un disque (5') et sont reliées par l'intermédiaire d'au moins une ouverture radiale (4''') avec d'autres sections axiales en quinconce (4'') ou avec l'intérieur (7) du capuchon (1'') pour former des canaux d'air traversants. En outre, la paroi du capuchon, la paroi frontale et la paroi d'impact ou bien le ou les étagements ou encore le ou les disques sont solidaires les uns des autres.
