Abstract
A writing instrument may include a barrel having a longitudinal axis, a cartridge, a writing tip, a self-retracting and sealing system for sliding the cartridge inside the barrel between a first position wherein the writing tip extends outside the barrel and a second position wherein the writing tip is retracted, the system comprising a button configured to move the cartridge between the first and the second position, and a sealing member configured to be actuated between a closed position closing a writing passage of the writing instrument, wherein the cartridge is configured to actuate the sealing member to the open position when the cartridge is moved to the first position and to allow the sealing member in the closed position when the cartridge is in the second position.
Claims20
A writing instrument comprising:
- a barrel having a longitudinal axis;
- a cartridge;
- a writing tip provided at one end of the cartridge;
- a self-retracting and sealing system configured to slide the cartridge axially inside the barrel between a first extended forward position wherein the writing tip extends outside the barrel and a second retracted rearward position wherein the writing tip is retracted inside the barrel from the first extended forward position along an axial rearward direction, the self-retracting and sealing system comprising:
- a button configured to, when actuated, move the cartridge into the first extended forward position, and when not actuated, move the cartridge into the second retracted rearward position;
- and
- a sealing member configured to be actuated between a closed position where the sealing member closes a writing passage of the writing instrument and an open position where the writing passage is not closed by the sealing member;
- and
- a cap configured to be actuated so as to slide in an opposite manner with respect to the sliding of the cartridge along the longitudinal axis,
- wherein the cartridge is configured to actuate the sealing member from the closed position to the open position when the cartridge is moved from the second retracted rearward position to the first extended forward position and to allow the sealing member to move from the open position to the closed position when the cartridge is in the second retracted rearward position.

- and
- a sealing member configured to be actuated between a closed position where the sealing member closes a writing passage of the writing instrument and an open position where the writing passage is not closed by the sealing member;
- wherein the cartridge is configured to actuate the sealing member from the closed position to the open position when the cartridge is moved from the second retracted rearward position to the first extended forward position and to allow the sealing member to move from the open position to the closed position when the cartridge is in the second retracted rearward position, wherein the button has a forward end configured to move radially away from the sealing member when the button is actuated, thereby allowing the sealing member to move to the open position, and wherein when a state of the button changes from being actuated to not being actuated, the forward end of the button pushes the sealing member into the closed position.
