Abstract

Official abstract text for this publication.

A multi-function writing instrument comprises a body extending in an axial direction, at least two writing elements arranged inside the body, each writing element comprising a writing head able to take up a retracted position in which the writing head is stowed in the body and a writing position in which the writing head protrudes from the body, one of the writing elements being a lead-holder system comprising a lead-holder mechanism and a lead container, the lead container comprising a side opening for inserting leads.

First claim

Opening claim text (preview).

The invention claimed is: 1. A multi-function writing instrument comprising a body extending in an axial direction, the body including a front portion and a rear portion, at least two writing elements arranged inside the body, each writing element comprising a writing head able to take up a retracted position in which the writing head is retracted into the body and a writing position in which the writing head protrudes from the body, one of the writing elements being a lead-holder system comprising a lead-holder mechanism and a lead container, the lead container comprising a side opening for inserting leads, wherein the side opening is accessible for inserting leads into the lead container only after the front portion is separated from the rear portion. 2. A multi-function writing instrument according to claim 1 , comprising a lead retention element which is configured to take up a position for retaining leads in the lead container and an insertion position for inserting leads in the lead container through the side opening for inserting leads. 3. A multi-function writing instrument according to claim 2 , wherein the retention element is configured to pass from the retention position to the insertion position by a rotation about the axial direction of the retention element relative to the lead container. 4. A multi-function writing instrument according to claim 2 , wherein the retention element is a sleeve arranged around the lead container. 5. A multi-function writing instrument according to claim 4 , wherein the sleeve comprises a lead insertion window. 6. A multi-function writing instrument according to claim 1 , wherein the side opening for inserting leads has a length in the axial direction greater than or equal to 20 mm and less than or equal to 30 mm. 7. A multi-function writing instrument according to claim 1 , wherein the front portion and the rear portion are movable in rotation relative to one another about the axial direction. 8. A multi-function writing instrument comprising a body extending in an axial direction, two or more writing elements arranged inside the body, wherein the writing elements comprise a writing head configured to adopt a retracted position in which the writing head is stored inside the body and a writing position in which the writing head is projected outside the body, wherein one of the writing elements is a lead-holder system comprising a lead-holder mechanism and a lead container, the lead container comprising a lateral lead insertion opening, the writing instrument further comprising a lead retention element which is configured to take up a position for retaining leads in the lead container and an insertion position for inserting leads in the lead container through a side opening for inserting leads, wherein the retention element is a sleeve arranged around the lead container, and the sleeve is contained entirely within the body of the writing instrument. 9. A multi-function writing instrument according to claim 5 , wherein the sleeve is configured to pass from the retention position to the insertion position by a rotation about the axial direction of the retention element relative to the lead container. 10. A multi-function writing instrument according to claim 6 , comprising a lead retention element which is configured to take up a position for retaining leads in the lead container and an insertion position for inserting leads in the lead container through the side opening for inserting leads. 11. A multi-function writing instrument according to claim 10 , wherein the retention element is configured to pass from the retention position to the insertion position by a rotation about the axial direction of the retention element relative to the lead container. 12. A multi-function writing instrument according to claim 10 , wherein the retention element is a sleeve arranged around the lead container, and the sleeve is contained entirely within the body of the writing instrument. 13. A multi-function writing instrument according to claim 12 , wherein the sleeve comprises a lead insertion window. 14. A multi-function writing instrument according to claim 13 , wherein the sleeve is configured to pass from the retention position to the insertion position by a rotation about the axial direction of the retention element relative to the lead container. 15. A multi-function writing instrument according to claim 10 , wherein the front portion and the rear portion being movable in rotation relative to one another about the axial direction. 16. A multi-function writing instrument according to claim 11 , wherein the front portion and the rear portion are movable in rotation relative to one another about the axial direction. 17. A multi-function writing instrument according to claim 12 , wherein the front portion and the rear portion are movable in rotation relative to one another about the axial direction. 18. A multi-function writing instrument according to claim 13 , wherein the front portion and the rear portion are movable in rotation relative to one another about the axial direction. 19. A multi-function writing instrument according to claim 8 , wherein the body comprises a front portion and a rear portion, and the sleeve is accessible for loading leads into the lead container only when the front portion and rear portion of the body are separated from one another. 20. A multi-function writing instrument according to claim 19 , wherein the sleeve is configured to pass from the retention position to the insertion position by a rotation about the axial direction of the retention element relative to the lead container, wherein the sleeve comprises a lead insertion window, wherein leads are insertable through the side opening only when the lead insertion window of the sleeve at least partially radially aligns with the side opening.
