Description

Locking structure of the push-button bottle

This creation involves a locking technology for a push-type spray bottle.

According to the prior art, there is a container for containing liquid, particularly a press-type container structure, in which a press-type nozzle is arranged on the open end of a container bottle, and a detachable end cap is covered around the press-type nozzle, and liquid substances can be placed in the container bottle. When people want to use the liquid substance in the container, they first remove the end cap from the container bottle, then press the push-type nozzle, use the liquid sucking assembly connected to the push-type nozzle to suck out the liquid substance in the container bottle and spray it out from the nozzle of the push-type nozzle; after use, they re-close the end cap on the upper opening of the container bottle and cover the push-type nozzle inside to prevent the push-type nozzle from spraying the liquid substance due to accidental pressing.

Since the end cap of the above-mentioned liquid container must be removed from the container bottle before each use, and then the end cap cover must be put back on the container bottle after use, if the end cap is not put back on the container bottle immediately or the end cap is loosened from the container bottle, the push-type spray head can easily spray liquid cosmetics due to accidental compression; therefore, patents such as Chinese patents CN112777123 "Spray pump and liquid dispensing device" and CN214030142 "Atomizing spray head device" were developed, so that the spray head is stored in an external shell and a protective cap to prevent accidental compression.

However, although the spray head is covered inside, the protective cap is not locked. Therefore, when such a spray bottle is carried outside, it may be pressed accidentally and the liquid material may be squeezed out. Therefore, the structural design of the spray bottle needs to be further improved, which is what the industry is eager to break through.

In order to solve the above-mentioned shortcomings of the existing technology, the main purpose of this invention is to provide a locking structure for a press bottle, which uses the concave and convex design of the action ring and the press cap to produce a locking and anti-mispressing function, in order to overcome the difficulties in the existing technology.

Technical means to solve the problem. To achieve the above purpose, this invention provides a locking structure for a push bottle, which is applied between the outer pressure cap of the push bottle and its upper shell. Its features include an action ring combined with the bottle body, a groove on the action ring, the upper shell is sleeved on the push valve end of the bottle body, and is positioned corresponding to the action ring, and an outer pressure cap is covered on the push valve. The outer pressure cap has a protrusion, so that the protrusion can produce a locking effect corresponding to the top edge of the action ring, or present an unlocking state corresponding to the groove; by this design, the push bottle can achieve the effect of preventing accidental pressing in the locked state.

The protruding portion of the outer pressure cover is provided with a protruding rib, and the upper shell is provided with an embedding groove for the protruding rib to be embedded and limited and can move up and down.

Among them, the top of the action ring is provided with a latching edge, and the upper shell body is provided with a convex ring corresponding to the latching edge to engage with it and limit the position.

Among them, the outer wall of the action ring is convexly provided with a limit block, and the inner wall of the upper shell is provided with two guide grooves, and the two guide grooves can be respectively provided for the limit block to provide the limit of the rotation locking or unlocking of the outer pressure cover.

The bottle body is provided with an embedded protrusion, and the action ring is provided with a locking groove that is mutually embedded with the protrusion.

The action ring and the bottle body are integrally formed.

The bottle body includes an inner bottle and an outer bottle, the inner bottle is placed in the outer bottle, and the outer bottle is integrally formed with the action ring, and the inner bottle is locked and combined with the push valve.

The drawings used in this article are only for illustration and auxiliary description, and may not be the actual proportion and precise configuration of this invention after implementation. Therefore, the proportion and configuration of the attached drawings should not limit the patent scope of this invention in actual implementation. This should be stated in advance.

Please refer to the first and second figures for the three-dimensional appearance and the exploded view of this invention. The locking structure of the push bottle of this invention mainly includes a bottle body (1) for containing liquid, an upper shell (2) and an external pressure cover (3), wherein a push valve (4) is locked at the opening of the bottle body (1), and the upper shell (2) is sleeved and installed on the outside of the push valve (4), and the external pressure cover (3) is sleeved on the push valve (4), and the external pressure cover (3) can be pressed to link the push valve (4) to suck out the liquid in the bottle body (1), and its characteristics are:

The bottle body (1) is combined with an action ring (5) for positioning and is locked on the inner side of the upper shell body (2). The upper shell body (2) can rotate relative to the action ring (5). A groove (51) is provided downward from the top edge of the action ring (5). A protrusion (31) is provided on the outer pressure cover (3). A rib (311) is provided on the protrusion (31). An embedding groove (21) is provided on the upper shell body (2) to allow the rib (311) to be embedded and movable in the embedding groove (21). The protrusion (31) can produce a locking effect corresponding to the top edge of the action ring (5), or present an unlocking state corresponding to the groove (51).

In addition to the above features, a latch edge (52) is provided on the outer side of the top edge of the action ring (5), and a convex ring (22) is provided on the inner side of the upper shell (2) corresponding to the latch edge (52) to engage with the latch edge for position limiting; at the same time, a limit block (53) is convexly provided on the outer wall of the action ring (5), and two guide grooves (23) are provided on the inner side wall of the upper shell (2), and the two guide grooves (23) can be respectively provided for the limit block (53) to latch, so as to provide the limit of the rotation locking or unlocking of the external pressure cover (3).

During assembly of the invention, an embedding protrusion (11) is provided on the edge of the bottle at the open end of the bottle body (1), and the action ring (5) is provided with a snap-fit groove (54) that engages with the embedding protrusion (11), so that the action ring (5) can be fixed on the bottle body (1) without rotation. Then, the upper shell body (2) is sleeved and installed on the outside of the action ring (5), and the upper shell body (2) uses the protrusion (22) to correspond to the action ring (5). The latch edge (52) on the top edge of the ring (5) is relatively displaceable, which means that the upper shell (2) can be rotated and displaced; then, the external pressure cover (3) is covered on the outside of the push valve (4), and the protruding rib (311) is correspondingly embedded in the embedding groove (21) of the upper shell (2) to limit the position.
