Definitions

  • the present invention relates to writing instruments, and, more particularly, to retractable marker pens.
  • a marker pen includes a filter filled with ink, a pen nib formed at an end of the filter, and a body encasing the filter.
  • the pen nib is exposed out of the body when in use, and therefore, the marker pen must further have a means for allowing the pen nib to be hermetically received in the body, in order to prevent drying of ink in the nib.
  • a representative example of conventionally used sealing means includes a cap for covering a front end of the body encasing the filter.
  • conventional marker pens using a cap as a nib sealing means have the problems that a user has to manually open and close the cap whenever using the marker pen and that the marker pen may be unavailable upon the loss of the cap.
  • the cap is loosely closed, there is the risk of vaporization of the ink. hi the worst case, if the cap is completely separated, children are exposed to the danger of suffocation by the separated cap. However, when the cap is tightly closed for the purpose of eliminating the vaporization of ink, it may be difficult to open the cap for use.
  • retractable marker pens have been developed and used conveniently.
  • a pen nib can be extruded out of a body when in use by simply pressing a filter support provided at the body. If the filter support is again pushed after completing the use of the marker pen, the pen nib can be intruded into the body.
  • Such a conventional retractable marker pen still has a need for installing a nib sealing means to the body, in order to allow the pen nib to be hermetically received in the body, to prevent drying of ink in the nib.
  • FIG. 1 illustrates one example of a conventional nib sealing means for a marker pen.
  • the sealing means include a bonded member 201, which is made of a soft material and will be installed to a front end of a body.
  • a pair of push plates 202 are attached to opposite sides of the bonded member 201 such that a pen nib 203 is extruded out of the bonded member 201 by forcibly opening a mouth of the bonded member 201 between the push plates 202.
  • the nib 203 is intruded into the bonded member 201, and the push plates 202 act to press the mouth of the bonded member 201, so as to seal the bonded member 201.
  • a problem of the above described sealing means is that the fabrication of the sealing means is difficult because of the complicated configuration. Furthermore, due to the fact that the pen nib 203 is extruded out of and intruded into the bonded member 201 by forcibly opening a specific region of the bonded member 201, an ink- vehicle may be applied onto the specific region, thus producing a vehicle layer thereon. The vehicle layer consequently causes a gap in the bonded member, resulting in a degradation in the sealing efficiency of the bonded member. As a solution to achieve an improved sealing efficiency as well as easy fabrication of the conventional retractable marker pen, as shown in FIG.

  • the tubular sealing member 301 is formed, at an inner periphery thereof, with a sealing protrusion 3011, and the nib cylinder 303 is formed, at an outer periphery thereof, with a sealing protrusion 3031.
  • a cap 302 is installed to a front end of the tubular sealing member 301, to define a sealing space for a pen nib 304, protruded from a front end of the nib cylinder 303, within the tubular sealing member 301.
  • the cap 302 is provided with a pulling string 305.
  • the pen nib 304 is pushed forward for the use of the marker pen, the pen nib 304 is exposed to the outside as a front end of the nib 304 pushes and opens the cap 302. After the marker pen is completely used, the pen nib 304 is intruded into the tubular sealing member 301, and simultaneously the cap 302 is closed under the operation of the pulling string 305.
  • a problem of the marker pen having the above described configuration is that an ink discharged from the nib 304 is continuously applied onto a specific region of the cap 302 and remains an ink vehicle layer on the specific region, and the ink vehicle layer may result in a degradation in the sealing efficiency of the cap 302.
  • the present invention has been made in view of the above problems, and it is an object of the present invention to provide a retractable marker pen in which a cap for sealing a pen nib can be opened or closed under operation of a separate opening device without the risk of touching with the pen nib, thereby preventing an ink discharged from the pen nib from being applied onto the cap differently from the prior art in which a cap is pushed and opened by a pen nib, and consequently eliminating the risk of a degradation in the sealing efficiency of the cap even after the long time use of the marker pen.

As a result, the retractable marker pen according to the present invention can achieve an improved operating reliability as well as high- quality products.

Abstract

La présente invention concerne un instrument d'écriture, et plus particulièrement, un marqueur escamotable. Dans un marqueur classique à rabattement, un capuchon pour empêcher l'encre de sécher dans une pointe de stylo est conçu pour être ouvert par poussée de la pointe. Un problème découlant de cette configuration c'est que la couche de transport d'encre produite au niveau du capuchon empêche la fermeture hermétique du capuchon, entraînant ainsi une détérioration dans l'efficacité d'étanchéité du capuchon. Afin de résoudre ce problème, dans le marqueur escamotable de la présente invention, suite à l'ouverture du capuchon par poussée par une partie de poussée qui est définie dans un bras coulissant solidaire d'un élément de corps de marqueur, la pointe est saillante hors d'un boîtier du marqueur, de sorte qu'il n'y ait pas d'encre sur le capuchon, et permettant par conséquent une efficacité d'étanchéité améliorée du capuchon.
