With continued reference to fig. 3 and 4, the locking groove 43 of the embodiment of the present invention further includes a first boss 44 and a second boss 45 sequentially spaced along the screwing direction of the second thread 42, and the groove 46 is located between the first boss 44 and the second boss 45; the first boss 44 and the second boss 45 are both arranged at the end of the second thread 42 in a protruding manner towards the container body 40; thus, the first boss 44 and the second boss 45 protrude from the end of the second thread 42, so that the heights of the first boss 44 and the second boss 45 in the direction towards the container body 40 are larger than the thickness of the second thread 42 in the direction towards the container body 40, the locking block 13 can be lifted towards the container body 40 by the first boss 44 in the process of screwing in the groove 46, so that the elastic sealing plug 20 is greatly compressed to improve enough reverse elasticity, and then the locking block 13 falls into the groove 46 again, so that the locking block 13 can be firmly clamped in the groove 46. When the container cover 10 needs to be opened, the container cover 10 needs to be pressed by providing a larger force to enable the locking block 13 to be separated from the groove 46 and reach the height of the first boss 44 to unlock, and in general, the child cannot independently press the container cover 10 and can provide such a larger force, so that the false opening and eating behaviors of the child are effectively prevented, and the safety of the child is ensured.
The groove 46 is defined by a first boss side wall surface 441 provided on the first boss 44, a second boss side wall surface 451 provided on the second boss 45, and a bottom wall surface 461 located between the first boss side wall surface 441 and the second boss side wall surface 451; the size of the locking block 13 is adapted to the groove 46 and locked to the first boss side wall surface 441, the second boss side wall surface 451 and the bottom wall surface 461, and the intermittent distance between the locking block 13 and the end of the first thread 12 in the screwing direction is greater than or equal to the length size of the first boss 44 in the screwing direction of the second thread 42. The first boss side wall surface 441 prevents the lock block 13 from being reversely screwed out to prevent erroneous opening, and the second boss side wall surface 451 prevents the lock block 13 from continuing to rotate in the screwing direction to prevent the container cover 10 from being excessively screwed to damage the container cover 10 and the container body 40. Meanwhile, the locking block 13 can be abutted against the bottom wall surface 461 under the elasticity of the elastic sealing plug 20, so that the locking block 13 and the bottom wall surface 461 are in a pre-tightening state, and the firmness of the matching between the locking block 13 and the groove 46 is enhanced. The size of the locking block 13 in the embodiment of the invention can be adapted to the groove 46, that is, the locking block 13 can be just clamped into the groove 46, so that the container cover is easy to loosen left and right due to an excessive gap between the locking block 13 and the groove 46 is prevented. Meanwhile, in the embodiment of the present invention, the intermittent distance between the locking block 13 and the end of the first thread 12 in the screwing direction is greater than or equal to the length dimension of the first boss 44 in the screwing direction of the second thread 42, that is, after the locking block 13 is clamped into the groove 46, the first boss 44 can be smoothly embedded into the gap between the end of the first thread 12 and the locking block 13, so as to prevent the interference of the locking firmness between the locking block 13 and the groove 46 caused by mutual interference of the ends of the first boss 44 and the first thread 12.
In the embodiment of the present invention, the locking block 13 may be formed by cutting off the end of the first thread 12 in the screwing direction of the first thread 12, so that the locking block 13 is a part of the first thread 12, so that the locking block 13 can be screwed into the second thread 42 normally, and of course, the locking block 13 may also be a small block which is independently arranged and has a width smaller than the pitch of the second thread 42 so as to be screwed into the second thread 42 normally.
As shown in fig. 5, in the embodiment of the present invention, the angle between the bottom wall surface 461 and the side wall surface of the first boss is a1, and the angle between the bottom wall surface 461 and the side wall surface of the second boss is a2.
