Definitions
- the present invention essentially relates to a self-centering seal intended to equip for example a container lid or cap.
- Leaktightness to the product contained in a container, or to the vapor emanating from this product, is generally obtained by compression of a seal housed in a capsule or cover which can be screwed onto the open end of the container.
- the seal is generally glued or snapped into the bottom of the cover, which leads to a number of drawbacks.
- This phenomenon is all the more important on containers or pots with a large opening diameter.
- the seal in the event of surface defects or flatness of the opening end of the pot, the seal can be injured and its performance called into question.
- the object of the present invention is to remedy the above drawbacks in particular by proposing a seal ensuring in all circumstances a good seal, posing no problem of compatibility with the product in the container, remaining not very fragile, avoiding all problems inherent in friction when closing the container, and also solving all concentricity problems.
- the subject of the invention is a seal for a cover or the like forming, for example, a screw cap on the open end of any container, and of the type comprising a disc or a ring the periphery of which is provided.
- protruding means capable of sealing by compression of the seal on the opening end of the container, characterized in that said protruding means consist of an annular lip projecting from one face of the disc or ring and having at its end a substantially conical bearing face.
- the substantially conical bearing face of the aforementioned lip converges towards the axis of the disc or ring in a direction distant from the plane thereof.
- This seal is further characterized in that the other face of the aforementioned disc or ring comprises, in line with the aforementioned lip, an annular boss, the bearing face of which has the shape of a flat.
- the invention also relates to a cover, for example forming a screw cap on any container or pot, and equipped with a seal meeting the above characteristics, this cover being characterized in that said seal is mounted floating substantially parallel to the bottom of the cover in an annular groove in this cover, the width of which is slightly greater than the thickness formed by the aforementioned disc or ring and the aforementioned boss.
- the seal as well as the container are made of polyolefin such as polypropylene for example, while the cover is made of a styrene-acrylonitrile copolymer to allow relative sliding of the seal relative to said cover.
- This cover can be of the oriented plug type, by quarter-turn screwing for example.
- a seal 5 is mounted floating in the cover 2, substantially parallel to its bottom 3, and this thanks to an annular groove 6 formed between said bottom 3 and the skirt 4 of the cover 2. As can be seen in the single figure, the seal 5 is retained by its periphery 5a in the annular groove 6.
- This seal 5 is in the form of a disk made of flexible synthetic material and one of the 7 faces of which has an annular lip 8 projecting from the face 7 and the end of which forms a substantially conical bearing face 9.
- the other face 10 of the disc-shaped seal 5, or else which could still be in the form of a ring, has an annular boss 11 whose bearing face 12 on the bottom 3 of the cover 2 has the shape of a flat.
- the width or height of the annular groove 6 in the cover 2 will be slightly greater than the thickness formed by the periphery 5a of the disc 5 and the circular boss 11, so that the seal 5 is retained floatingly in the cover 2.
- the open end 1 of the container R has a corresponding conical support face 13 complementary to the conical support face 9 of the circular lip 8 projecting from the face 7 of the seal 5.
- the materials constituting the cover 2 and very particularly the bottom 3 on the one hand, and the seal 5 on the other hand are chosen so that they provide a sliding cooperation between these two elements .
- the container R or its through end 1 at the very least, can be made of a polyolefin such as polypropylene for example, as well as the seal 5, this so as to allow a support and a watertight attachment between the lip annular 8 and the through end 1 of the container R.
- a polyolefin such as polypropylene for example
- the cover 2 for its part, can be made of a styrene-acrylonitrile copolymer to which a slip agent such as for example silicone can optionally be added, to allow the seal 5, or more precisely the circular boss, to slide. 11 of this seal on the bottom 3 of the cover 2.
- a slip agent such as for example silicone
- the materials involved in the production of the cover, the seal and the container closable by the cover may be other than those presently described.
- the obturator disc which complements the seal can be omitted.
