Description

push drink bottle

technical field

The invention relates to a beverage bottle.

Background technique

At present, beverages are mainly bottled. Due to the improvement of people's awareness of life quality and safety and health awareness, there are higher requirements for the appearance, shape and internal structure of beverage bottles. Therefore, colorful beverage bottles have appeared. How to change the form of the bottle, its basic structure includes a bottle body and a bottle cap, the body has a bottleneck, the bottleneck is formed with a bottleneck, and the bottle cap is arranged on the bottleneck and covers the bottleneck. However, they all avoid going astray due to the constraints of positioning dimensions, and adopt an auxiliary part structure to realize the sealing and firmness of the bottle body and the bottle cap and the convenience of opening. Similar documents can refer to the Chinese utility model patent "safe and sanitary beverage bottle" (authorized announcement number CN201071123Y) whose patent number is ZL200720055709.7. This patent adds a sealing gasket as a sealing auxiliary part; see application number 201210061752.X The Chinese invention patent application publication "a kind of beverage bottle" (authorization announcement number is CN102582929A), and this patent has increased sealing plug as sealing auxiliary parts. Although these auxiliary parts have improved the sealing performance of the beverage bottle, more parts not only increase the assembly process, but also increase the cost of materials and processing costs.

Also someone has proposed a beverage bottle structure with fewer parts, see the Chinese utility model patent "Beverage Bottle" (authorized announcement number is CN201670478U) whose patent number is ZL201020212617.7. , the outer surface of the ring wall has an external thread adapted to the internal thread on the inner wall of the bottle mouth. After the bottle cap and the bottle body are closed, the inner and outer sides of the bottle neck are threaded on the bottle cap to achieve double locking, greatly improving the sealing performance, and , no additional components are added.

Contents of the invention

The technical problem to be solved by the present invention is to provide a push-type beverage bottle with a cap that is easy to open and has good sealing performance in view of the above-mentioned technical status quo.

The technical solution adopted by the present invention to solve the above-mentioned technical problems is: a press-type beverage bottle, including a bottle body and a bottle cap. To cover and cover the bottle mouth, it is characterized in that the outer side wall of the lower end of the bottle neck protrudes with a locking part, and correspondingly, the inner lower end of the bottle cap has a claw that snaps and fits with the aforementioned locking part, and, The outer wall of the bottle cap is provided with a pressing block, and when the pressing block is pressed inward along the radial direction of the bottle cap, the aforesaid claws tilt outward along the radial direction of the bottle cap and can break away from the engaging portion.

The outer periphery of the pressing block is formed with anti-skid lines. A force application portion extends radially outward from the upper end of the pressing block. Easy to apply force. The anti-skid texture can adopt horizontal texture, inclined texture, net texture or wave texture, and the cross-section of the anti-skid texture can be rectangle, trapezoidal triangle, etc., which will not be further developed here.

The outer side wall of the upper end of the bottle neck is formed with an annular protrusion, while the diameter of the inner side wall is in an inverted cone shape. Correspondingly, the inner top of the bottle cap is formed with an inverted tapered ring that can be adapted to the inner wall of the bottle neck. An annular area is formed between the outer wall of the inverted tapered ring and the inner wall of the bottle cap to fit sealingly with the aforementioned annular protrusion. The annular convex part is adapted to the ring area of the bottle cap to obtain a double locking and sealing, which is an interference and sealing fit of the tapered inclined surface. At the same time, the catch of the engaging part and the bottle cap obtains another locking and sealing, double locking and sealing The connection between the bottle cap and the bottle body is firm, and at the same time, the sealing performance is better, and there are no redundant parts, which is beneficial to the reduction of raw material cost and processing cost.

The outer end surface of the annular protrusion is in the shape of a convex spherical surface, and correspondingly, the inner top of the bottle cap is formed with a concave spherical surface. The error spherical interference fit locking structure is adopted to make the connection between the two more firm.

The caliber of the inner wall of the bottleneck can be in the shape of an inverted cone, a polygonal pyramid, a triangular cone, a rectangular cone, a rectangular rounded pyramid or a wavy cone.

Further, the middle part of the bottle neck has an external thread, and correspondingly, the inner middle part of the bottle cap has an internal thread adapted to the aforementioned external thread.

Both the bottle body and the bottle cap are made of synthetic resin. The synthetic resin has a large elastic-plastic ratio, which is beneficial to the sealing and locking of the bottle cap and the bottle body.

The operation of the pressing block is facilitated, the bottom end of the pressing block is connected to the outer side of the claw, and a pressing gap is formed between the inner side wall and the outer side wall of the bottle cap.

The middle part of the inner side wall of the pressing block protrudes with a supporting part which is against the outer side wall of the bottle cap, and the end part of the supporting part is pointed. The supporting part serves as a supporting point, and the linkage between the pressing block and the claw can be realized by using the principle of leverage.

There are at least two pressing blocks and they are evenly arranged around the peripheral wall of the bottle cap. Of course, a single pressing block can also be provided, but more than two are preferred.

Compared with the prior art, the present invention has the advantages that: when a force is applied to the pressing block lightly, the jaws will tilt outward along the radial direction of the bottle cap and can break away from the engaging part, so that the bottle cap can be easily opened, and the operating range is large. It is small, comfortable to operate, convenient and easy to implement, and at the same time, the claws cooperate with the engaging part, and the sealing performance is better, both of which are taken into account.
