Abstract
A dispenser for a substance such as lipstick. The dispenser includes containing a pusher for the substance and a declutchable drive to move the pusher in an axial direction within the body to dispense the substance. The pusher returns to an initial position when the declutchable drive is declutched.
Claims30
A dispenser comprising a body within which a pusher is movable, declutchable drive means for driving said pusher in axial displacement so as to dispense a substance, and return means for returning the pusher into an initial position when said drive means are declutched, wherein said return means comprise a resilient member working in traction, said resilient member being mounted such that said resilient member is elongated so as to exert a return force on said pusher, as said pusher is moved to dispense the substance said return force increasing as the elongation of said resilient member increases.
A dispenser comprising:
- a body;
- a pusher that is axially movable within the body, the pusher including a rod;
- a declutchable drive member, the declutchable drive member being capable of engaging the rod and, thereby, driving the pusher in axial displacement to dispense a substance;
- and
- a resilient member working in traction engaging the pusher to return the pusher to an initial position when the declutchable drive member is declutched said resilient member being mounted such that said resilient member is elongated so as to exert a return force on said pusher as said pusher is moved to dispense the substance, said return force is increasing as the elongation of said resilient member increases.
A dispenser comprising a body within which a pusher is movable, declutchable drive means for driving said pusher in axial displacement so as to dispense a substance, and return means for returning the pusher into an initial position when said drive means are declutched, wherein said return means comprise a resilient member working in traction, wherein the body of the dispenser has first and second portions capable of rotating relative to each other, wherein the pusher has a thread, the pusher is mounted with the ability to slide in the first portion of the body but without the ability to rotate relative to said first portion, and the drive means is secured to the second portion of the body, said drive means comprising at least one drive member movable between a driving position in which it engages the thread of the pusher so that relative rotation between the two portions of the body causes the pusher to move axially, and a declutched position in which it ceases to be engaged with the thread of the pusher and enables the pusher to return to its initial position under a return force of the resilient member, wherein the two portions of the body are separable and are shaped so as to be engageable one in the other, the drive member being organized in such a manner that inserting one of the portions in the other portion causes the drive member to be displaced from its declutched position towards its drive position, and vice versa when said portions are separated, and wherein the drive member comprises at least one resilient tab shaped to present a certain amount of resilience in the axial direction when it is engaged with the pusher, thereby enabling the pusher firstly to return slightly towards its initial position in the event of the user exerting axial thrust on the pusher while applying the substance, and secondly allowing the pusher to escape if said thrust exceeds a predetermined force.
A dispenser comprising:
- a body;
- a pusher that is axially movable within the body, the pusher including a rod;
- a declutchable drive member, the declutchable drive member being capable of engaging the rod and, thereby, driving the pusher in axial displacement to dispense a substance;
- and
- a resilient member working in traction engaging the pusher to return the pusher to an initial position when the declutchable drive member is declutched, wherein the body of the dispenser has a first portion and a second portion, the first portion being capable of being rotated relative to the second portion;
- the pusher has a thread and is mounted with the ability to slide in the first portion but without the ability to rotate relative to the first portion;
- and the declutchable drive member is movable between a driving position in which it engages the thread of the pusher so that relative rotation between the first portion and the second portion causes the pusher to move axially within the body, and a declutched position in which the drive member ceases to be engaged with the thread of the pusher allowing the pusher to return to its initial position under a return of the resilient member, wherein the first portion and the second portion are separable and are shaped to be engageable with each other;
- and the drive member is arranged such that engaging the first portion and the second portion causes the drive member to be displaced from a declutched position towards a drive position, and separating the first portion and the second portion causes the drive member to be displaced from the drive position towards the declutched position and wherein the drive member includes at least one resilient tab shaped to present resilience in the axial direction when the drive member is engaged with the pusher, the at least one resilient tab enabling the pusher to return slightly toward its initial position when a user exerts sufficient axial thrust on the pusher and allowing the pusher escape if
