Embodiment Construction

[0022] The present invention will be further described below in conjunction with the drawings.

[0023] Such as figure 1 As shown, the present invention includes a housing 1 and an inner cover 3 rotatably arranged in the housing 1. The inner wall of the inner cover 3 is provided with a thread, and also includes an opening member arranged in the housing 1. The operation of the opening member The end is located outside the housing 1, the opening piece is movably fitted with the housing 1 in the axial direction, and the opening piece is in contact with the inner cover 3 through a rotation stop structure during pressing operation. During installation, first install the opening piece into the casing 1. The opening piece can be fitted with the casing 1 through a guiding structure, such as guide grooves and guiding ribs; or it can be loosely fitted directly into the casing 1. Internal axial movement. Then screw the inner cap 3 onto the threaded bottle mouth 6. Finally, buckle the shel...

Abstract

The invention discloses a bottle cover, particularly relates to a press-type bottle cover, and provides a press-type bottle cover which is sealed reliably. The press-type bottle cover comprises a shell and an inner cover arranged in the shell in a rotatable manner, wherein a screw thread is formed on the inner wall of the inner cover. The press-type bottle cover is characterized by also comprising an opening piece arranged in the shell, wherein the operating end of the opening piece is positioned outside the shell, and is movably matched with the shell in an axial direction; and the opening piece is contacted with the inner cover through a rotation stopping structure during pressing. As the opening piece is matched with the inner cover through the rotation stopping structure during pressing, the opening piece is only pressed to make the inner cover rotate when the press-type bottle cover is used; a bottle body is sealed by the screw thread on the inner cover, and the sealing effect is reliable; and furthermore, when the opening piece is not pressed, the inner cover cannot be operated; and therefore, misoperation is prevented.

Description

Technical field [0001] The invention relates to a bottle cap, in particular to a press type bottle cap. Background technique [0002] Push-type bottle caps have been widely used in wine packaging. They only need to press the button on the cap to open the cap, which is more convenient to operate and can prevent accidental opening of the cap. [0003] For example, the publication date is July 26, 2006, and the Chinese patent "A Bottle Cap Device with Locking Hook" with the publication number CN1807193A discloses such a push-type bottle cap, including a sleeve, an inner sleeve, a button, and a spring. , Bottle stopper, lock hook sleeve and transition bottleneck. The inner sleeve is lined in the cylinder sleeve to stabilize the lock hook sleeve. The inside of the lock hook sleeve is composed of twelve locking hooks arranged vertically along the circumferential direction. The locking hooks have Elastic, the top end is a hook end that can be elongated in the radial direction, and one si...
