Problems solved by technology

This friction engagement between the screw threads of the bottle neck and the cap also often affects the quality of the liquid seal between the cap and bottle.
If the cap is loose on the bottle neck due to the cap not being screwed down entirely on the bottle neck liquid contained in the bottle could potentially leak t

Embodiment Construction

[0020] Each of the embodiments of the bottle neck closure apparatus to be described could simply be used to close the opening of a bottle, or could be used as an attachment for another component to the bottle, for example a hand operated trigger sprayer. In each of the embodiments to be described the component parts of the embodiments are constructed of materials typically used in the construction of bottle and cap closures, for example plastic material. A first embodiment of the bottle and cap closure apparatus of the invention is shown in FIGS. 1 and 2.

[0021]FIG. 1 shows an upper portion of a bottle 12 having a cylindrical bottle neck 14. The bottle neck 14 surrounds an opening to an interior volume of the bottle. The bottle neck and bottle opening have a center axis 16 that defines mutually perpendicular axial and radial directions relative to the bottle 12 and the bottle neck 14. The bottle neck 14 has a cylindrical exterior surface 18 that extends upwardly from the bottle 12 t...

Abstract

A closure apparatus for a bottle neck and cap increases the torque necessary to remove the cap from the bottle neck. Projections are provided on one of the bottle neck exterior and cap interior, and indentations are provided on the other of the bottle neck exterior and cap interior. When the cap is secured on the bottle neck, the projections engage in the indentations. The engagement of the projections in the indentations requires an increased torque to remove the cap from the bottle neck.

Description

BACKGROUND OF THE INVENTION [0001] (1) Field of the Invention [0002] The present invention pertains to a closure apparatus for a bottle neck and cap that increases the torque necessary to remove the cap from the bottle neck. More specifically, projections are provided on one of the bottle neck and cap interior, and indentations are provided on the other of the bottle neck and cap interior. When the cap is secured on the bottle neck, the projections engage in the indentations. The engagement of the projections in the indentations requires an increased torque to remove the cap from the bottle neck. [0003] (2) Description of the Related Art [0004] A typical bottle and cap closure apparatus comprises a bottle neck having one or more exterior screw threads that engage with interior screw threads of the cap. The cap is positioned on top of the bottle neck and turned in the clockwise direction relative to the bottle to screw the interior threads of the bottle cap onto the exterior threads ...
