Abstract

A water bottle-straw assembly comprising a screw-threaded cap base including a lift-lower cap attached at one side thereof and a through hole in which a suction base is inserted. The suction base has a protruding suction end having a valve and a flange providing an air guiding groove. A straw is inserted into the suction base and a flexible tube is telescopically connected to the lower end of the straw to allow use with containers of varying sizes.

Claims

1. An improved structure of a water bottle-straw assembly, comprising:

a water bottle body having an open end and a closed end;

a cap base screwed to the open end of the water bottle body, wherein a through hole and an air inlet are formed on said cap base, a rabbet groove is provided around said through hole beneath said cap base, and said cap base is also provided with a lift-lower cap at its edge;

a suction base made of silicone and being made integral, wherein a first flange is formed around said suction base, a suction end is protruded on said suction base, a second flange is formed around the low part of said suction end, a valve is provided at the top of said suction end, an air-guiding groove is formed said first flange and, an air inlet valve is provided in said air-guiding groove;

a straw, the upper end of which is connected into said suction end of said suction base and the lower end of which touches the inner bottom of the water bottle body;

wherein said suction end goes through said through hole of said cap base in such a way that said two flanges of said suction base are rabbetted with said rabbet groove and the edge of said through hole, respectively, and that said suction end is protruded above said cap base; and

wherein said air-guiding groove on said flange corresponds to and is thus air-connected to said air inlet on said cap base.

2. The improved structure according to claim 1, wherein a flexible tube is telescopically connected to said lower end of said straw, thereby the total length of said straw being adjustable to make said tube touch the inner bottom of the water bottle body by means of telescoping, in order for use in water bottles with various capacity depths.
