Definitions
- the present invention relates to any metallic annular part coming from force fit onto any plastic element in particular of a device product distribution, and more particularly any collection device such as than a hoop, an overcap, a cover for a pusher or a stopper, for example.
- the present invention provides a solution to this problem and therefore avoids the aforementioned drawback.
- Document BE-545,477 discloses a threaded metallic element screwed onto a threaded plastic ring.
- the subject of the present invention is a metal covering member intended for be force-fitted onto an essentially cylindrical plastic element, characterized in that it comprises an annular side wall provided on its internal face with at least one relief extending obliquely over at least part of the height of said wall lateral, the internal diameter of said covering member at said at least one relief being slightly less than the outside diameter of said plastic element, said plastic element conforming by creep, after force fitting of the overlap, the shape of said at least one oblique relief so as to allow said covering member to be removed by unscrewing said plastic element.
- said at least one oblique relief has an elongated shape forming a internal thread on the annular side wall of the covering member.
- the internal face of the wall lateral annular of said covering member is provided with a single oblique relief extending over approximately the entire circumference of said annular wall.
- the internal face of the side wall of said covering member is provided with several parallel oblique reliefs distributed around its circumference.
- the difference between the outside diameter of the plastic element and the internal diameter of the covering member at the level of said at least one relief is weak, said oblique relief being able to be produced in the form of a gadroon or a rib.
- annular metal part is represented under the shape of a hoop or a plug, but it is understood that the invention also relates well to any other metal covering member intended to be press fitted onto a cylindrical plastic element in particular of a product dispenser, such as by example a covering or an overcap for a pusher or a collar.
- the covering member is metallic and annular and is intended to be force-fitted onto a plastic element of a product dispenser, for example example.
- the plastic element can be for example a snap ring intended to fix the dispensing member (a pump for example) to the container containing the product.
- the internal diameter of the covering member 1 is typically approximately equal to the outside diameter of the plastic element on which it is fitted. So said covering member 1 can slide more or less easily on the outer wall lateral of said plastic element.
- the covering member 1 comprises on the internal face 3 of its annular side wall 2 at least one relief 4 extending obliquely over a portion the height of said side wall 2.
- the internal diameter of the member overlap 1 at said at least one oblique relief 4 is less than the diameter outside of the plastic element on which said covering member comes be fitted.
- said at least one relief 4 can be implemented in the form of ribs or gadroons.
- the outer surface 5 of the covering member 1 remains perfectly cylindrical, which may be a choice from an aesthetic point of view.
- said at least one oblique relief 4 has an elongated shape to form an internal thread on the side wall annular 2 of the covering member.
- the internal face 3 of the side wall 2 of the covering member 1 comprises a single relief 4.
- this oblique relief extends approximately over a complete turn of the circumference of the side wall 2. It is very clear in this case that the slope of said relief 4 is relatively small.
- the difference between the outside diameter of the plastic element and the internal diameter of the covering member 1 at said at least one relief oblique 4 is weak.
- the covering member 1 intended to be force-fitted onto an element plastic 10 is disposed on the latter, the lower end 6 of said at least one relief 4 abutting and preventing said covering member 1 from sliding along said plastic element.
- the covering member is then force-fitted onto said element plastic according to well known techniques.
- the difference in hardness between the metal of the covering member 1 and the plastic of the plastic element provides a effective fitting.
- the plastic of the plastic element follows by creep, after a period of time which depends on the hardness of said plastic, the shape of said at least one relief 4 of the covering member 1.
- the invention therefore makes it possible to very simply separate the metal from the plastic, especially in product distributors without modifying the installations of mounting of said distributors.
