Description

A combined bottle cap

Technical field

The present invention relates to the field of packaging technology, and in particular to a combined bottle cap.

Background technique

The current packaging bottle is as shown in Figure 1. The upper end of the packaging bottle 100 is provided with a liquid discharge pump head 200. Press the liquid discharge pump head 200 downward to discharge liquid. The liquid discharge pump head 200 is covered with a top cover 300 and the inner wall of the top cover 300 A convex ring 3001 is provided, through which the top cover 300 clamps the outer wall of the liquid outlet pump head 200 . During use, it is laborious to pull out the top cover 300 and is difficult to open, especially for products where part of the convex ring 3001 and the liquid discharge pump head 200 are tightly matched. The top cover 300 is easy to fall off after being pulled out, and is easily contaminated after being dropped. If the contaminated top cover 300 is continued to be used, it will also contaminate the liquid outlet, affecting the next use, and there is a hygiene problem.

Contents of the invention

The object of the present invention is to overcome the above-mentioned shortcomings of the prior art and provide a combined bottle cap, which is easy to open and does not need to be separated from the bottle body during use. The bottle cap is not easy to fall off and is more hygienic to use.

In order to achieve the above objects, the technical solution of the present invention is:

A combined bottle cap, including a bottle cap used to connect a bottle body, a pressing pump head is provided on the top of the bottle body, and a liquid outlet is provided on the side of the pressing pump head, and the bottle cap includes a second bottle cap and a first bottle cap, The outer wall of the first bottle cap fits the inner wall of the second bottle cap. The first bottle cap can rotate around the central axis of the second bottle cap. The second bottle cap includes a first cylinder ring and a second cylinder ring located on both sides. The first cylinder The ring and the second cylinder ring are spliced to form a complete ring. The inner wall of the first cylinder ring is provided with a first groove. The inner wall of the second cylinder ring is provided with a second groove connected with the first groove and located below the second groove. The third groove is connected up and down. The first groove and the second groove form a closed loop. The outer wall of the first bottle cap is provided with a protruding block. The rotation of the first bottle cap can cause the protruding block to move between the first groove and the second groove. It slides in the groove, and the bottom of the first bottle cap is connected with a connecting block. The first bottle cap includes a second ring at the bottom. When the protruding block is located in the first groove, the outer end of the liquid outlet is located inside the second ring, and the connection The block is located above the top of the pump head. When the convex block enters the third groove downward along the second groove, the bottom surface of the connecting block fits the top of the pump head. The liquid outlet is connected to the outside world. Press the top of the first bottle cap to Make the protruding block slide up and down along the inner wall of the third groove and press the pump head to discharge liquid.

There is a fixed sleeve on the outer wall of the pressing pump head, and the outer side of the fixed sleeve is connected to the second bottle cap.

The fixed sleeve includes a collar cover at the top, and the connecting block passes through the collar cover and can slide up and down along its inner wall.

The connecting block includes a chassis located at the bottom. The chassis is located below the collar cover. The outer wall of the upper end of the connecting block is covered with a spring. The upper end of the spring resists the lower end of the collar cover, and the lower end of the spring resists the upper end of the chassis.

The protruding block is cylindrical and the cylindrical axis direction is along the radial direction of the second bottle cap.

The second ring is in the shape of a semicircle, and the bottom of the second ring is lower than the bottom of the liquid outlet.

The inner wall of the first cylinder ring is provided with a clamping groove. The clamping groove is located below the first groove and connected to it. The clamping groove and the third groove are arranged oppositely, and the bottom of the convex block can be clamped into the clamping groove.

The first cylinder ring is provided with a through hole, which is located below the card slot, and the liquid outlet can be connected to the external connection through the through hole.

The second groove includes chute grooves located on both sides, the chute grooves on both sides gradually slope downward inwardly, and the third groove is located below the downwardly sloping end of the chute.

The first cylindrical ring is provided with first convex rings at its upper and lower ends, and the second cylindrical ring is provided with second convex rings at its upper and lower ends. The outer walls of the first convex ring and the second convex ring are connected with fixed rings.

The beneficial effects of the present invention are:

The rotatable first bottle cap rotates to open or close the liquid outlet, which can block the liquid outlet from the outside world when not in use, which is beneficial to the storage of liquid in the bottle, and when in use, there is no need to remove the first bottle cap. Eliminates the problem of easily losing the bottle cap after removing it.

When the first bottle cap is closed, it cannot be pressed down, and the fixing sleeve that can directly contact the upper end of the pump head is located above the pump head. There is a certain distance between the two, so the pump head cannot be opened to prevent unauthorized use. When in use, the carrier mistakenly presses the bottle, causing the liquid in the bottle to spray out.

When the first bottle cap rotates, the first bottle cap is pushed up by the spring, so that the convex block resists the first groove or the second groove when sliding, which can improve the user's feel when opening or closing, and the convex block can When the block slides to the third groove or the card slot, it is not easy for the first bottle cap to rotate too fast, causing the convex block to rotate through the third groove and the card slot without entering the third groove or the card slot, thus affecting the use. .
