Definitions
- the present invention relates to a tight screw cap for a threaded neck of a container and more specifically a cap of the type having an external cylindrical skirt internally threaded surrounding a bowl bottom, that is to say a bottom having a circular bottom wall surrounded by a cylindrical side wall connecting it to the upper edge of the outer skirt of the stopper, the outside diameter of the lateral cylindrical wall of the cup bottom corresponding to the inside diameter of the threaded upper end of the container neck and its length being less than that of the cylindrical skirt of the plug.
- This type of stopper which is often used with blown plastic containers such as PVC, is itself made of injected plastic material such as polyethylene, and the most frequently encountered problem is obtaining good tightness despite the relative flexibility of the material of the container and the cap, especially when the container contains a pressurized liquid such as a carbonated drink.
- the present invention aims to provide a stopper capable of withstanding the pressure of a carbonated drink.
- the bottom wall of the bowl bottom is connected to its lateral cylindrical wall by a part in the shape of a crown, of bi-frustoconical cross-section delimiting, at the periphery of the bottom wall, an annular groove of substantially triangular section projecting from the bottom wall, on the same side as the free end of the outer skirt.
- the angle at the top of the most central frustoconical part of the crown is between 105 ° and 155 ° and, preferably, is equal to 130 °
- the angle at the top of the outermost frustoconical part of the crown is between 35 ° and 85 ° and, preferably, is equal to 60 °
- the values of these angles at the top being related to the internal diameter the neck, that is to say the outside diameter of the cylindrical side wall of the bottom of the cuvette of the stopper.
- the internal thread of the outer skirt of this plug is a cylindrical thread and advantageously comprises two threads.
- the sealed screw cap 2 for the container threaded neck of the invention is of the type having a cylindrical outer skirt 3 and a cup bottom 4.
- the outer skirt 3 has, on its internal face, a thread 5 and, on its outer face, grooves 6 facilitating its operation by the user.
- the bowl bottom 4 comprises a bottom wall proper of circular profile, surrounded by a lateral cylindrical wall 8 shorter than the outer cylindrical skirt 3, secured by its lower edge 8a to the bottom wall 7 and connected by its edge upper 8b, at the upper edge 3a of the outer skirt 3.
- annular space 9 capable of accommodating the threaded upper end 11a of the neck 11 of the container when the cap 2 is screwed onto it, as illustrated in FIG. 2.
- the outside diameter of the lateral cylindrical wall 8 is therefore substantially equal to the inside diameter of the threaded upper end 11a of the neck 11 of the container.
- This stopper which is made of injected plastic material such as polyethylene, is intended to be used for closing containers of blown injected plastic material such as PVC or the like.
- the object of the present invention is to make this stopper perfectly sealed, even when the container contains a pressurized liquid such as a carbonated drink, generating inside the container a pressure capable of causing the stopper to be ejected.
- the bottom wall 7 of the bowl bottom 4 is connected to the lower edge 8a of the lateral cylindrical wall 8 by a part 12 in the form of a crown of bi-frustoconical cross section defining, at the periphery of the bottom wall 7, an annular groove 13 of substantially triangular section and the circular edge 13a of which projects from the bottom wall 7, on the same side as the free edge of the outer skirt 3.
- the angle at the top of the most central frustoconical part 13b of the wall of the groove 13 is equal to 130 °
- l 'angle at the top of the outermost frustoconical part of the wall of the groove 13 is equal to 60 °.
- the thread 5 formed in the internal face of the outer skirt 3 is double thread, which obviously implies that the thread corresponding to the upper threaded end 11a of the neck 11 of the container is also provided with a double thread.
- this plug 2 can, as well as other types of plugs, be equipped, if desired, with a tearable tamper-evident belt.
