Definitions

  • the invention relates to a cap for writing instruments, in particular for ballpoint pens, but also for other writing, drawing or painting devices, the cap having at least one air channel penetrating the end face.
  • 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 clothing soiling and against damage to the writing tip and which nevertheless enables continuous air circulation when it is not connected to the writing instrument .
  • the cap 1 shown in FIGS. 1 to 3 is formed as a whole in one piece and has an integrally formed clip 10.
  • the closed end face 2 is provided with two semicircular, the end wall 3 breaking through, axially extending sections 4 'of a continuous air channel 4.
  • a disk 5 'held by webs 6' is formed as an impact wall 5 acting from the inside.
  • the air channel 4 becomes continuous and opens into the interior 7 of the cap 1.
  • a serving as a transverse baffle 5 annular circumferential step 5 ⁇ causes a deflection of the air flow and a reliable protection of the - here containing a writing ball 12 - writing tip 11 from damage by axially penetrating into the cap 1 foreign bodies.
  • caps which are generally made of thermoplastic material by injection molding.
  • baffles 5 serving as disks 5 ' these are connected via radial and possibly also axially extending webs 6 to the end wall 3 and / or the cap wall 8.
  • the cap 1 having a clip 10' is attached to the shaft 14 of a writing instrument also provided with a writing ball 12.
  • a round disk 5 ′ designed as a baffle 5 is used, which has practically the same cross section or the same diameter, like the axially adjoining section 4 'of the air duct 4.
  • This disc 5' is fixedly connected by webs 6 with the cap wall 8 or with the end wall 3 or 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 in the area of the writing tip 11 ⁇ existing air openings of the writing instrument in the closed position, ie, when pushed onto the shaft 14 and positively held with the annular bead 15, the assembly position is hermetically sealed. On the other hand, when the cap 1 ⁇ is released or even when the cap is released, outside air can enter the interior 7 via the sections 4 ′, 4 ′ ′ ′ and 4 ⁇ .
  • the seal 9 is cup-shaped here and integrally formed on the baffle 5 or on the disc 5 'held by webs 6'.
  • any other seal shape and type can be selected.
  • this embodiment according to FIG. 7 in addition to the effects according to the task, there is the additional advantage that even with sealing caps and similar closures, both when plugging onto the writing, drawing or painting device, and when detaching it, no compression is formed on the one hand or The formation of negative pressure on the other hand arises and that the leakage resistance of such writing instruments is also increased thereby.
  • the recessed disc 5' also offers the possibility of the protected arrangement of a product, company or other identification in an advantageous manner. Blurring or damaging a mark made there is practically not possible.

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.

Claims (6)

1. Capuchon (1, 1′, 1˝) pour instruments d'écriture, en particulier pour stylos à bille, comportant au moins un canal d'air (4) traversant le bout ou côté d'extrémité (2), capuchon sur lequel le canal d'air (4) est conformé pour s'étendre axialement et radialement et se trouve exclusivement dans la zone du côté d'extrémité (2), lequel est fermé par ailleurs, et sur lequel les segments orientés axialement (4′) du canal d'air (4) sont délimités par au moins une paroi de rebondissement (5) s'étendant transversalement, ou par au moins un gradin (5˝) ou un disque (5′), et sont reliés à travers au moins un orifice radial (4′′′) à d'autres segments axiaux (4˝), disposés décalés, ou au volume intérieur (7) du capuchon (1, 1′, 1˝) pour la formation de canaux d'air (4) traversants, caractérisé en ce que la paroi latérale (8) du capuchon, la paroi d'extrémité (3) et la paroi de rebondissement (5), ou le ou les gradins (5˝), ou bien le ou les disques (5′), sont réalisés d'un seul tenant.
2. Capuchon selon la revendication 1, caractérisé en ce que le ou les disques (5′) et/ou le ou les gradins (5˝), servant de paroi de rebondissement (5), est ou sont disposé(s) avec un décalage axial par rapport à la paroi d'extrémité (3).
3. Capuchon selon la revendication 1 ou 2, caractérisé en ce que la paroi de rebondissement (5) présente essentiellement la même section droite que le segment axialement voisin (4′, 4˝) du canal d'air (4) et forme pratiquement son prolongement axial.
4. Capuchon selon une des revendications précédentes, caractérisé en ce que la paroi de rebondissement (5) est reliée par des barrettes ou entretoises (6) à la paroi d'extrémité (3) ou à la paroi latérale (8) du capuchon.
5. Capuchon selon une des revendications précédentes, caractérisé en ce qu'un élément d'étanchéité (9) est coordonné à la paroi de rebondissement (5).
6. Capuchon selon une des revendications précédentes, caractérisé en ce que le canal d'air (4) présente, sur toute son étendue, une aire de section ou de passage d'au moins 5 à 15 mm², de préférence de 7 à 10 mm².
