Abstract
A sealing cap, which engages a neck of a bottle, including a top wall from which extend a sidewall and a sealing skirt. The sidewall includes a cap thread to be screwed onto a neck thread of the neck of the bottle around a screwing axis. The sealing skirt includes an inclined sealing surface to be pressed against a corresponding surface of the neck on an opposite side from the surface including the neck thread, upon screwing the cap thread onto the neck thread. The inclined sealing surface is formed by a wall of the sealing skirt surrounding a cavity. An inclination angle between the inclined sealing surface and the screwing axis is between 7° and 25°. An axial length of the cap thread, taken parallel to the screwing axis, is higher than or equal to 1.5 times a pitch of the cap thread.
Claims21
A sealing cap to engage a neck of a bottle, the sealing cap comprising a first top wall from which extend a first sidewall and a sealing skirt, wherein:
- the first sidewall comprises a cap thread to be screwed onto a neck thread of the neck of the bottle around a screwing axis,
- the sealing skirt comprises an inclined sealing surface to be pressed against a corresponding surface of the neck of the bottle on an opposite side from the surface comprising the neck thread, upon screwing the cap thread onto the neck thread,
- the inclined sealing surface is formed by a wall of the sealing skirt surrounding a cavity,
- an inclination angle between the inclined sealing surface and the screwing axis is between 7° and 25°, and
- an axial length of the cap thread, taken parallel to the screwing axis from a level of a proximal end of the inclined sealing surface to a level of a distal end of the cap thread, is higher than or equal to 1.5 times a pitch of the cap thread.
