Dispensing device for a receptacle containing a product of liquid to pasty consistency

A dispensing device for a receptacle containing a product of liquid to pasty consistency, including a sealing capsule fitted with a dispensing opening, said capsule including a means of closing which is in the form of a clamp having two arms linked by a crosspiece, said crosspiece having one area which serves to close the said opening, the ends of said arms farthest away from the crosspiece having means of articulation on a section fixed to said receptacle, said means of articulation allowing displacement of said clamp along the axial direction of said receptacle in order to distance the crosspiece from said opening, wherein rotation of the clamp will cause displacement of the crosspiece at a tangent to the said opening, said device including a cam system, located between the arms of the clamp and a part of the receptacle causing, from commencement of rotation of the cam from the closed position, said displacement of the clamp along said axial direction, wherein the means of articulation of the clamp include, for each arm, a non-circular axis cooperating with a window having an internal surface engaged by said axis in such a way that, whatever the angle of the axis, the contact between the axis and said internal surface of the window will be sufficiently close to avoid any sudden movement of the clamp in relation to said receptacle, while initiating the aforementioned displacement along said axial direction,

• said receptacle being closed by a picot system fixed to said crosspiece of said clamp, wherein said axis includes a component having a base having two shoulders which together form an angle, said component having an upper part presenting a trapezoid with rounded angles, said trapezoid having a large base which faces upwardly, said window having a lower section which is substantially semi-circular and an upper part which is triangular, said window having a base including a boss for cooperation with said shoulders during rotation of said component, said component having an axis engaged in a longitudinal slit provided in a portion of said receptacle.

A dispensing device for a receptacle containing a product of liquid to pasty consistency, including a sealing capsule fitted with a dispensing opening, said capsule including a means of closing which is in the form of a clamp having two arms linked by a crosspiece, said crosspiece having one area which serves to close the said opening, the ends of said arms farthest away from the crosspiece having means of articulation on a section fixed to said receptacle, said means of articulation allowing displacement of said clamp along the axial direction of said receptacle in order to distance the crosspiece from said opening, wherein rotation of the clamp will cause displacement of the crosspiece at a tangent to the said opening, said device including a cam system, located between the arms of the clamp and a part of the receptacle causing, from commencement of rotation of the cam from the closed position, said displacement of the clamp along said axial direction, wherein the means of articulation of the clamp include, for each arm, a non-circular axis cooperating with a window having an internal surface engaged by said axis in such a way that, whatever the angle of the axis, the contact between the axis and said internal surface of the window will be sufficiently close to avoid any sudden movement of the clamp in relation to said receptacle, while initiating the aforementioned displacement along said axial direction,

• said non-circular axis being located on the internal face of each said arm of said clamp, said window being located on a part of said receptacle, said window being circular and located in a middle plane Of said receptacle and including a hollow and a boss diametrically opposite said hollow and corresponding to the closed position of said clamp.

A dispensing device for a receptacle containing a product of liquid to pasty consistency, including a sealing capsule fitted with a dispensing opening, said capsule including a means of closing which is in the form of a clamp having two arms linked by a crosspiece, said crosspiece having one area which serves to close the said opening, the ends of said arms farthest away from the crosspiece having means of articulation on a portion of said receptacle, said means of articulation allowing displacement of said clamp along the axial direction of said receptacle in order to distance the crosspiece from said opening, wherein rotation of the clamp will cause displacement of the crosspiece-at a tangent to the said opening, said device including a cam system, located between the arms of the clamp and a part of the receptacle causing, from commencement of rotation of the cam from the closed position, the aforementioned displacement of the clamp along said axial direction, wherein the means of articulation of the clamp include, for each arm, a non-circular axis cooperating with a window having an internal surface engaged by said axis in such a way that, whatever the angle of the non-circular axis , the contact between the non-circular axis and the internal surface of the window will be sufficiently close to avoid any sudden movement of the clamp in relation to said receptacle, while initiating the aforementioned displacement along the axial direction, said dispensing opening comprising a slit formed in a dome shaped membrane located at one end of said receptacle, said crosspiece being dimensioned to come into contact with said membrane when in a closed position, said cam system including at least one ramp fixed to a part of one of said clamp and said receptacle and a ramp follower being associated with the other of said clamp and said receptacle to cause axial displacement upon commencement of rotational movement of said clamp, said ramp including a groove set into said receptacle, said groove being arc shaped and convexly curved relative to said opening of said receptacle, said receptacle having a middle plane with said groove being located in said middle plane, at least one of said arms of said clamp including an internal face confronting said receptacle and a cam follower comprising a tappet disposed on said internal face and engaged in said groove.
