Definitions
- the main subject of the present invention is a cover with seal combined with any container.
- the tightness to the product contained in a container, or to the steam from this product is usually obtained by compression of a seal housed in a capsule or cover which can be screwed onto the through end of the container.
- the seal is generally glued or snapped in the bottom of the lid, which leads to some number of drawbacks.
- This phenomenon is all the more important on containers or pots whose diameter of the through end is tall.
- the seal may be injured and its performance questioned.
- the present invention offers a cover with seal ensuring in all circumstances a good seal, posing no compatibility issue with the product in the container, remaining not very fragile, avoiding all problems inherent in friction when closing of the container, and also solving all the problems of concentricity.
- the invention relates to a cover with seal combined with container which seal is mounted in a groove annular cover and has an annular lip projecting from one face of the joint and presenting at its end a substantially conical bearing face converging towards the axis of the joint in a direction distant from its plan and likely to cooperate by compression of the joint with the through end of the container, characterized in that said bearing face tapered seal lip cooperates with one side corresponding and complementary support forming the open end of said container, while the part of the conical bearing face closest to the axis of the seal rests on a sealing disc retained on a shoulder provided on the through end of the container.
- the seal and the container are made of polyolefin such as polypropylene by example, while the cover is made in one styrene-acrylonitrile copolymer to allow relative sliding of the seal with respect to said cover.
- This cover may 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 a groove annular 6 formed between said bottom 3 and the skirt 4 of the cover 2.
- seal seal 5 is retained by its periphery 5a in the annular groove 6.
- This seal 5 is present in the form of a plastic disc flexible and one of the 7 faces of which has a lip annular 8 projecting from face 7 and of which the end forms a substantially conical bearing face 9.
- the support face 9, as it appears clearly on the figure converges towards the X axis of the joint 5 which merges with the axis of the cover 2, and this in a direction going away from the plane of the joint 5.
- the other face 10 of the disc-shaped seal 5, or 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 slightly greater than the thickness formed by the periphery 5a of the disc 5 and the circular boss 11, of so that the seal 5 is retained so floating in the cover 2.
- the open end 1 of the container R has a face corresponding and complementary conical support 13 of the conical bearing face 9 of the circular lip 8 making projection from the face 7 of the seal 5.
- the materials making up cover 2 and all 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 open end 1 at all less, can be made of a polyolefin such as polypropylene for example, as well as the seal sealing 5, this so as to allow support and watertight attachment between the annular lip 8 and the open end 1 of the container R.
- a polyolefin such as polypropylene for example, as well as the seal sealing 5, this so as to allow support and watertight attachment between the annular lip 8 and the open end 1 of the container R.
- the cover 2 meanwhile, can be made in one styrene-acrylonitrile copolymer which can be possibly added a slip agent such as by example silicone, to allow sliding of the joint sealing 5, or more precisely of the circular boss 11 of this seal on the bottom 3 of the cover 2.
- a slip agent such as by example silicone
- this seal will be obtained for a rotation of minimum screwing of the cap or cover 3, so that said cover can be advantageously used for perform oriented capping, i.e. capping carried out by a quarter-turn screwing for example of the plug.
- This is useful when this plug is present example a square shape in front, when closing, coincide with the square shape of the container R.
