As shown in fig. 1 to 7, the present invention discloses a container, which comprises a container body and a bottle cap, wherein the container body is provided with a bottle mouth for assembling the bottle cap, and the bottle cap is a combined bottle cap and comprises a base 1 and a cover body 2.

The base 1 is provided with an inverted buckle I102 and a limit boss 104 positioned above the inverted buckle I102, the limit boss 104 is arranged on the outer wall of the base 1, and the cover body 2 is provided with an inverted buckle II 205.

When the base 1 is connected with the bottle mouth, the reverse buckle I102 is close to the inner wall of the base 1 under the pressure of the bottle mouth. After the connection is finished, the reverse buckle I102 is restrained by the axial direction of the protruding part of the outer wall of the bottle opening to prevent the base 1 from being separated from the bottle opening, at the moment, a pulling force is applied to the base 1, the top of the reverse buckle I102 is blocked by the protruding part of the periphery of the bottle opening, and meanwhile, the reverse buckle I102 cannot be deformed to be separated from the gap due to the fact that the gap between the base 1 and the bottle opening is small, and therefore the base 1 is firmly fixed on the bottle opening.

Similarly, when the cover 2 is connected to the base 1, the reverse buckle II205 is close to the inner wall of the cover 2 under the pressure of the limiting boss 104 on the base 1. After the connection is completed, the reverse buckle II205 is axially constrained by the limit boss 104 to prevent the cover 2 from separating from the base 1, at this time, a pulling force is applied to the cover 2, the top of the reverse buckle II205 is blocked by the limit boss 104, and meanwhile, the reverse buckle II205 cannot be deformed to separate from the gap due to the small gap between the cover 2 and the base 1, so that the cover 2 is firmly fixed on the bottle mouth.

Further, the cover body 2 includes an annular connecting wall 201, a top cover 202, and a tamper strip 203; the undercut II205 is provided on the inner wall of the annular connecting wall 201. The top cover 202 is provided with a section of arc-shaped surrounding blocking part 214 extending along the circumferential direction and a hinge part 208 located between two ends of the arc-shaped surrounding blocking part 214 at a certain interval L2, wherein L2 is smaller, and the hinge part 208 and the arc-shaped surrounding blocking part 214 are not connected in the circumferential direction, so that the movement smoothness of the top cover 202 is improved. The hinge part 208 is integrally connected with the annular connecting wall 201, the bottom of the arc-shaped surrounding part 214 is provided with an anti-theft groove 213, the length of the anti-theft groove 213 is not more than half of the perimeter of the cover body 2, a certain distance L1 is arranged between the two ends of the anti-theft groove 213 and the corresponding end parts of the arc-shaped surrounding part 214, and L1 is larger so as to ensure that the connecting body II215 has enough length. The anti-theft strip 203 is arranged at the anti-theft slot 213, and the upper edge and the lower edge of the anti-theft strip are integrally connected with the corresponding parts of the arc-shaped surrounding part 214 and the annular connecting wall 201 through the connecting body I209. The bottom of the arc-shaped surrounding part 214 at the position of the non-anti-theft slot is integrally connected with the corresponding part of the annular connecting wall 201 through a plurality of connecting bodies II 215.

The connector I209 may be a plurality of connecting bridges distributed at equal intervals, or may be a connecting strip having a length equal to that of the anti-theft strip 203 and having a thin size, and the thin size ensures that the connecting strip can be broken under a tearing operation to tear off the anti-theft strip 203. The connecting body II215 is a plurality of connecting bridges distributed at equal intervals. When the lid body 2 is opened, the tamper-proof strip 203 is removed, and then the top lid 202 is opened upward, and the connecting body II215 is broken by the pulling force of the lid opening, so that the top lid 202 can be completely opened. The anti-counterfeiting capacity of the bottle cap is improved through the two structures, and secondary use is avoided.

Further, one or both ends of the antitheft strip 203 are provided with a tearing head 204 protruding outward, and the tearing operation of the antitheft strip 203 can be better completed by the tearing head 204. The tear tab 204 may also be used to position the closure relative to the container, for example, when the container itself has protruding structures such as handles, the tear tab 204 is positioned on the opposite side of the protruding structures. The front portion of the top cover 202 is further provided with a protrusion 210, and the opening operation can be better performed by the protrusion 210.

Further, the hinge portion 208 is provided with a limiting structure 211 which enables the top cover 202 to be opened at a certain angle relative to the annular connecting wall 201 after the anti-theft strip 203 is separated, the limiting structure 211 is a structure with two lower ends and a middle higher end, and the top cover 202 can be kept at the angle position when being opened to a certain angle through the limiting structure 211 so as to completely expose the bottle mouth, while the hinge portion 208 in the prior art has no fixed keeping function, and the angle can not be kept after the top cover 202 is opened, so that the pouring of the content in the bottle is influenced. The opening angle of the top cover 202 is limited by the shape of the structure of the limiting structure 211, with different structures corresponding to different opening angles. The outer wall of the hinge part 208 is recessed inwards relative to the outer wall of the annular connecting wall 201, and the thickness of the part, close to the limiting structure 211, of the hinge part 208 is smaller than that of the annular connecting wall 201. This configuration enables, on the one hand, the hinge portion 208 to be deformed under a smaller force to open the top cover 202, and on the other hand, the entire cover 2 is smooth at its outer periphery to facilitate quick grasping of the assembly device. In the prior art, the hinge part usually protrudes out of the outer peripheral surface of the bottle cap, so that the hinge part needs to be positioned firstly, and then the bottle cap can be accurately grabbed to complete the assembly of the bottle cap and the bottle mouth.

Further, the base 1 comprises an outer annular wall 101 for connecting the mouth of the bottle and a cover 108 for putting the mouth of the bottle into communication with or closing it from the outside; the reverse buckle I102 is provided on the inner wall of the outer annular wall 101, the peripheral side of the cover 108 is integrally and sealingly connected to the outer annular wall 101 via a connector III109, and the top of the cover 108 is provided with a pull ring 110. Connector III109 is a connecting ring along one circumference of the cover 108 and has a smaller thickness than the cover, so that it can be broken when the cover 108 is torn.

Further, the base 1 further comprises an inner annular wall 106 for fixedly arranging the sealing cover 108, and the inside of the cover 2 is provided with a sealing ring part 212 for forming sealing contact with the inner annular wall 106; the cap 108 is integrally sealed within the inner annular wall 106 by a connector III109, the inner annular wall 106 being integrally connected to the outer annular wall 101. Due to the sealing connection between the inner annular wall 106 and the sealing ring portion 212, when the cap 108 is removed, the cap 202 can still maintain the sealing function after being closed, thereby avoiding the leakage of the content in the bottle and ensuring the reliability of the subsequent use.

Further, the base 1 comprises a middle annular wall 103, the outer annular wall 101 being integrally connected to the middle annular wall 103 by an annular collar I105, the middle annular wall 103 being integrally connected to the inner annular wall 106 by an annular collar II 107. The middle annular wall 103 can play a role in sealing the bottle mouth on one hand and playing a role in clamping with the cover body on the other hand. In particular, the inner wall of the outer annular wall 101 is also provided with a projection I113. The base 1 and the bottle mouth are strongly combined through the reverse buckle I102, and the connection firmness is further strengthened through the buckling of the bulge I113 and the bulge on the outer wall of the bottle mouth, so that the double protection effect is achieved.

The outer wall of the middle annular wall 103 is also provided with a protrusion II114 corresponding to the protrusion I113, and the protrusion I113 and the protrusion II114 can be mutually matched to form clamping connection with a clamping groove structure on the bottle mouth.
