Child safety bottle

Abstract

The invention discloses a child safety bottle, and relates to the field of storage containers. The invention includes a bottle body and a bottle cap, wherein the bottle cap is screwed on the bottle body; the position of the bottle cap screwed on the bottle body is adjustable along an axis direction of the bottle body; the bottle cap is provided with an elastic sheet therein, which is configured to drive the bottle cap to move toward a side that is away from the bottle body; the bottle cap is provided with a first abutment block, and the bottle body is provided with a second abutment block; when the bottle cap screwed on the bottle body is located on a side that is close to the bottle body, a spiral trajectory of the first abutment block is separated from the second abutment block; and when the bottle cap screwed on the bottle body is located on a side that is away from the bottle body, the spiral trajectory of the first abutment block intersects with the second abutment block. The invention realizes the loosening and locking of the bottle body and the bottle cap. The structure of the bottle cap is relatively simple, which facilitates the production and fabrication of the bottle cap, and increases the production efficiency of the child safety bottle.

What is claimed is: 
     
         1 . A child safety bottle, wherein the child safety bottle comprises a bottle body and a bottle cap, and the bottle cap is screwed on the bottle body;
 wherein the position of the bottle cap screwed on the bottle body is adjustable along an axis direction of the bottle body;   the bottle cap is provided with an elastic sheet therein, which is configured to drive the bottle cap to move toward a side that is away from the bottle body;   the bottle cap is provided with a first abutment block, and the bottle body is provided with a second abutment block;   when the bottle cap screwed on the bottle body is located on a side that is close to the bottle body, a spiral trajectory of the first abutment block is separated from the second abutment block; and   when the bottle cap screwed on the bottle body is located on a side that is away from the bottle body, the spiral trajectory of the first abutment block intersects with the second abutment block.   
     
     
         2 . The child safety bottle according to  claim 1 , wherein:
 the elastic sheet abuts an outer side of the bottle body, and the radius of an inner wall of the elastic sheet is smaller than the radius of an outer wall of the bottle body; or   the elastic sheet abuts an inner side of the bottle body, and the radius of an outer wall of the elastic sheet is larger than the radius of an inner wall of the bottle body.   
     
     
         3 . The child safety bottle according to  claim 1 , wherein:
 the first abutment block is provided in plural, and the interval between adjacent first abutment blocks is larger than the length of the second abutment block; and/or   the second abutment block is provided in plural, and the interval between adjacent second abutment blocks is larger than the length of the first abutment block.   
     
     
         4 . The child safety bottle according to  claim 3 , wherein:
 the interval between adjacent first abutment blocks is equal to the interval between adjacent second abutment blocks.   
     
     
         5 . The child safety bottle according to  claim 1 , wherein:
 the first abutment block is provided with a first inclined surface for abutment with the second abutment block, the first inclined surface facing the bottle body; and/or   the second abutment block is provided with a second inclined surface for abutment with the first abutment block, the second inclined surface facing the bottle cap.   
     
     
         6 . The child safety bottle according to  claim 1 , wherein:
 when the bottle cap is screwed to an end close to the bottle body, an end of the first abutment block that is close to the second abutment block approaches an end of the second abutment block that is close to the first abutment block.   
     
     
         7 . The child safety bottle according to  claim 6 , wherein:
 a guide track, which faces the bottle cap, is provided on the bottle body; and   when the bottle cap is screwed to an end close to the bottle body, the first abutment block abuts the guide track.   
     
     
         8 . The child safety bottle according to  claim 1 , wherein:
 the bottle body is provided with an external thread, the bottle cap is provided with a plurality of spiral strips that are engaged with the external thread, and a second communication groove is formed on the external thread to form the second abutment block.   
     
     
         9 . The child safety bottle according to  claim 8 , wherein:
 the interval between the first abutment block and a lower spiral strip is larger than the pitch of the external thread; and/or   the interval between the first abutment block and an upper spiral strip is smaller than the pitch of the external thread.
