[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Example 1: Specific implementation method for solving the technical problem that the existing blow-molded bottles cannot complete the bottle cap opening operation on the bottle body

[0034] A blow-molded bottle that is easy to open comprises a bottle body 1, wherein the upper end of the bottle body 1 is connected with a bottle mouth 13, the upper end of the bottle body 1 is threadedly connected with a bottle cap 3, the bottle cap 3 comprises an opening portion 31 and a connecting portion 32, one end of the connecting portion 32 is rotatably connected with the opening portion 31, the connecting portion 32 is threadedly connected with the upper end of the bottle body 1, a slide groove 11 is arranged on one side of the bottle body 1, a groove 12 is arranged at the upper end of the slide groove 11, an L-shaped operating rod 2 is slidably arranged in the slide groove 11, the upper end of the L-shaped operating rod 2 extends into the groove 12, a spring is arranged between the upper end of the L-shaped operating rod 2 and the bottom of the groove 12, the spring is used to reset the L-shaped operating rod 2, and a reset spring can also be arranged between the bottom of the slide groove 11 and the bottom of the L-shaped operating rod 2. A push pin 21 is connected to the upper end of the L-shaped operating rod 2, and a locking rod 22 is slidably connected to the upper end of the bottle body 1. The locking rod 22 is slidably connected to the upper end of the bottle body 1 through a sliding sleeve. A spring is connected to the end of the locking rod 22, and the spring is used to reset the locking rod 22. The locking rod 22 is arranged between the threaded ring at the upper end of the bottle cap 3 and the bottle mouth 13. When the L-shaped operating rod 2 moves upward, it can drive the locking rod 22. A locking block 33 is provided on the inner side of the opening part 31 at a position corresponding to the locking rod 22. When the locking rod 22 is extended, it can be connected with the locking block 33 and limit the rotation of the opening part 31 and the connecting part 32. A trapezoidal hole 221 is provided on the locking rod 22. When the push pin 21 moves into the trapezoidal hole 221, it can drive the locking rod 22 to move in a direction away from the locking block 33.

[0035] in:

[0036] In order to automatically open the bottle cap 3, the bottle cap 3 is a spring buckle cap, and the opening portion 31 can be automatically opened when the locking rod 22 is disconnected from the locking block 33. The spring buckle cap is a mature existing technology, and an elastic member is usually provided between the opening portion 31 and the connecting portion 32 of the spring buckle, and the elastic member can bounce the opening portion 31 when the locking rod 22 is disconnected from the locking block 33, and automatically reset after the opening portion 31 is closed.

[0037] In order to improve the sealing performance of the bottle cap 3 , a sealing block 34 is provided inside the opening portion 31 , and the sealing block 34 is used to seal the bottle mouth 13 when the opening portion 31 is closed.

[0038] In order to facilitate the use of the present invention, the height of the bottle mouth 13 is higher than the setting height of the locking rod 22. Since the locking rod 22 and the sliding sleeve structure are located near the bottle mouth 13, the bottle mouth 13 needs to be at a certain height to prevent the locking rod 22 and the sliding sleeve structure from affecting the drinking action. After the height of the bottle mouth 13 is increased, the height of the bottle cap 3 should also be increased accordingly.

[0039] Embodiment 2: Manufacturing method of embodiment 1

[0040] Due to the arrangement of the groove 12 and the slide groove 11 in the bottle body 1 of the present invention, the blank mold can retain all the grooves 12 and part of the slide groove 11, and a protrusion for shaping the slide groove 11 can be arranged on the blow mold. Since the bottle cap and the L-shaped operating rod 2 have relatively complex structures, a customized part produced by a non-blow molding process can be selected and installed on the bottle body 1 after the blow molding of the bottle body 1 is completed.

[0041] The specific production process is as follows:

[0042] S1: Processing a mold blank with a threaded ring and a bottle mouth 13 at the top, and all grooves 12 and part of the slide grooves 11 at the upper end of the blank body;

[0043] S2: Blow molding the mold blank using a blow molding mold with a protruding block, the protruding block is used to form the slide groove 11;

[0044] S3: Installing a locking rod 22 and an L-shaped operating rod 2 on the blow-molded bottle body 1;

[0045] S4: Install the bottle cap 3, and perform an operation test on the L-shaped operating rod 2 and the locking rod 22 to ensure that when the L-shaped operating rod 2 is pushed upward in the slide groove 11, it can drive the locking rod 22 to move away from the locking block 33 and open the opening portion 31 of the bottle cap 3;

[0046] S5: Add water into the bottle body 1 to test the sealing performance of the bottle body 1. After the test, pour out the water to complete the production.

[0047] It should be noted that, in the description of the present invention, the directions or positional relationships indicated by the terms "up", "down", "left", "right", "front", "back", etc. are descriptions of the structure of the present invention based on the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0048] The "first" and "second" in this technical solution are only used to distinguish the names of the same or similar structures, or corresponding structures with similar functions, and are not an arrangement of the importance of these structures, nor do they have a ranking, comparison of size, or other meanings.

[0049] In addition, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense. For example, the connection can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be a connection between the two structures. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood based on the overall idea of ​​the present invention and the specific context of the present solution.
