This arrangement can not only expand the effective capacity of the bottle body 1, but also can cleverly use the bottom of the second recess 3 for pressing, which has the beneficial effects of limiting the amount of deformation of the bottle body 1 and extruding a quantitative liquid.

Wherein, a gap is left between the outer wall of the second recess 3 and the inner wall of the first recess 112.

Wherein, the cross section of the first recess 112 on the bottle body 1 is trapezoidal or approximately trapezoidal. The depth of the first recess 112 is determined by the shape of the bottle body and the amount of space compression corresponding to its deformation. The feedback of pressing the bottle body and the necessary extrusion volume, the pressing distance h of the first recess 112 is greater than 5 mm.

Wherein, the first recess 112, the second recess 3 and the bottle body 1 are integrally formed. Such a structure is simple, and can be designed to be integrated with the bottle body 1 through a mold structure for mass production.

The squeezing process during use of the present invention requires pouring the bottle body so that the mouth of the bottle faces downwards so that the liquid can flow out.

The above are only preferred embodiments of the present invention, and are not used to limit the scope of implementation of the present invention. Any modification or equivalent replacement of the present invention without departing from the spirit and scope of the present invention shall be covered by the protection of the scope of the patent application of the present invention.
