Abstract

A device for applying a removable substance in the form of a baton, has a substance carrier and a protective sleeve so that the substance carrier can be made to move relative to the protective sleeve. A movement part has a longitudinal slot in which the substance carrier is guided by a peg, and the substance carrier can be moved between a retracted position and an extended position. The longitudinal slot has a retaining portion assigned to the extended position, the central longitudinal axis of which runs at an angle to a central longitudinal axis of a movement portion of the longitudinal slot. The central longitudinal axis of the retaining portion and the central longitudinal axis of the movement portion enclose an obtuse angle.

First claim

The invention claimed is:

1. A device ( 1 ) for applying a transferable substance (M) in the form of a stick, comprising:
a substance carrier ( 2 ),
a protective sleeve ( 4 ) for the substance carrier ( 2 ), wherein the substance carrier ( 2 ) is configured to be displaced relative to the protective sleeve ( 4 ) in order to displace a free end region of the substance (M) into a freely projecting position, and
a movement part ( 5 ) with a longitudinal slot ( 6 , 6 ′), in which the substance carrier ( 2 ) is guided with a peg ( 7 ) engaging into the longitudinal slot ( 6 , 6 ′) such that the substance carrier ( 2 ) can be moved between a retracted position and an extended position,
wherein the longitudinal slot ( 6 , 6 ′) has a retaining portion ( 9 ) assigned to the extended position,
wherein a central longitudinal axis (y) of said retaining portion extends at an angle to a central longitudinal axis (z) of a movement portion ( 8 ) of the longitudinal slot ( 6 , 6 ′),
wherein the central longitudinal axis (y) of the retaining portion ( 9 ) and the central longitudinal axis (z) of the movement portion ( 8 ) include an obtuse angle (a),
wherein the substance carrier ( 2 ) is accommodated in a counter-retaining cylinder ( 3 ), in an inner wall of which a control groove ( 26 ) for the peg ( 7 ) is formed,
wherein the control groove ( 26 ) has assigned to the extended position an inclined surface ( 27 ) that leads to a transition to the cylindrical inner surface ( 28 ) of the counter-retaining cylinder ( 3 ), and
wherein the peg ( 7 ) is not or only partially in overlap with the inclined surface ( 27 ) in the extended position.

2. A device ( 1 ) for applying a transferable substance (M) in the form of a stick, comprising:
a substance carrier ( 2 ),
a protective sleeve ( 4 ) for the substance carrier ( 2 ), wherein the substance carrier ( 2 ) is configured to be displaced relative to the protective sleeve ( 4 ) in order to displace a free end region of the substance (M) into a freely projecting position, and
a movement part ( 5 ) with a longitudinal slot ( 6 , 6 ′), in which the substance carrier ( 2 ) is guided with a peg ( 7 ) engaging into the longitudinal slot ( 6 , 6 ′), such that the substance carrier ( 2 ) can be moved between a retracted position and an extended position,
wherein the longitudinal slot ( 6 , 6 ′) has a retaining portion ( 9 ) assigned to the extended position,
wherein a central longitudinal axis (y) of said retaining portion extends at an angle to a central longitudinal axis (z) of a movement portion ( 8 ) of the longitudinal slot ( 6 , 6 ′),
wherein friction cams ( 24 ) are formed on the substance carrier ( 2 ) and in frictional contact with the inner surface ( 29 ) of the movement part ( 5 ) during the displacement of the substance carrier ( 2 ),
wherein the friction cams ( 24 ) are designed non-circular with a longer dimension (a) and a shorter dimension (b), and wherein the longer dimension (a) essentially is realized in a direction of the movement portion ( 8 ), and
wherein, in a view of an outer edge ( 25 ) of the friction cam ( 24 ) from radially outside, the greatest dimension in the transverse direction is realized eccentric to the greatest dimension in the longitudinal direction.

3. The device according to claim 1 , wherein the retaining portion ( 9 ) has a catch projection ( 31 ), which is configured to be overrun by the peg ( 7 ), in order to retain the substance carrier ( 2 ) in the extended position.

4. The device according to claim 1 , wherein two opposing longitudinal slots ( 6 , 6 ′) are formed.

5. The device according to claim 4 , wherein an overrunnable catch projection ( 31 ) is formed in the respective retaining portion ( 9 ) of both longitudinal slots ( 6 , 6 ′).

6. The device according to claim 4 , wherein two pegs ( 7 ) are provided for respectively engaging into one of the longitudinal slots ( 6 , 6 ′).

7. The device according to claim 6 , wherein a control groove ( 26 ) is formed in the counter-retaining cylinder ( 3 ) for each peg ( 7 ).

8. The device according to claim 7 , wherein both control grooves ( 26 ) have an inclined surface ( 27 ) assigned to the extended position.

9. The device according to claim 2 , wherein, in a standing position of the device ( 1 ), in which its longitudinal axis (x) essentially is oriented vertically and the opening for displacing the substance (M) outward in a sliding manner is directed upward, the greatest dimension in the transverse direction is realized underneath a center of the greatest dimension in the longitudinal direction of the catch projection ( 31 ).

10. The device according to claim 2 , wherein the outer edge ( 25 ) of the friction cam ( 24 ) has a drop-shaped contour.

11. The device according to claim 1 , wherein the obtuse angle is between 100 and 170 degrees.
