[0025] Example 1

[0026] like Figures 1-8 As shown, the nursing solution bottle includes a bottle body 1 and a bottle cap, and the bottle body 1 is a round bottle. The bottle cap includes a bottle cap body 2 and a buckle 3, and the buckle 3 can be fastened onto the bottle cap body 2. The bottle cap body 2 and the buckle 3 are connected by a connector 10.

[0027] The outer wall of the bottle mouth of the bottle body 1 is provided with an external thread 4, a support ring 5, a step 6, and a retaining ring 8 in sequence from the head. The outer diameter of the external thread 4 can be the same as or different from the diameter of the support ring 5 and the retaining ring 8.

[0028] The outer circumference of the retaining ring 8 is evenly distributed with retaining posts 7, and the bottom of the retaining ring 8 is provided with a limiting ring 9. The limiting ring 9 is used to contact the opening of the bottle cap body 2, and a step 20 is provided between the limiting ring 9 and the shoulder of the bottle body 1.

[0029] Both step 1 (6) and step 2 (20) are cylindrical surfaces.

[0030] The bottle cap body 2 consists of a circular annular sidewall at the bottom and a flat top. The bottom of the circular annular sidewall has an internal thread that protrudes above the inner wall surface. The inner wall surface at the opening of the bottle cap body 2 is evenly provided with stop heads 18, which are recessed into the inner wall surface, i.e., located on the outer side of the inner wall surface. When the bottle cap body 2 is threadedly connected to the bottle body 1, the stop heads 18 and the stop posts 7 are staggered. The top of the bottle cap body 2 is provided with an upwardly extending liquid outlet head 11, and the bottle cap body 2 is provided with a recess 15.

[0031] An inner ring 19 extends downward from the top of the bottle cap body 2 on the inner side of the annular sidewall. When the bottle cap body 2 is screwed onto the bottle mouth, the bottle mouth sidewall is located between the inner wall surface of the bottle cap body 2 and the inner ring 19, which enhances the sealing of the bottle mouth threaded connection.

[0032] The head of the bottle cap body 2 is provided with a liquid outlet head 11, and the top of the liquid outlet head 11 is provided with a liquid outlet hole 13; the head of the liquid outlet head 11 is spherical, and the part below the head is columnar, and the bottom corner 24 of the bottom of the liquid outlet head 11 connected with the top of the bottle cap body 2 is arc-shaped and concave; a liquid outlet head sleeve 12 is arranged on the cap 3 corresponding to the liquid outlet head 11, the lower edge of the liquid outlet head sleeve 12 is arc-shaped, the bottom center of the liquid outlet head sleeve 12 is provided with a plug 14, the head of the plug 14 is a plane, and the part above the plane is a spherical surface, the plug 14 is used to plug at the liquid outlet hole 13 of the liquid outlet head 11, and when the cap 3 is clamped on the bottle cap body 2, the plug 14 is plugged at the liquid outlet hole 13 of the liquid outlet head 11; the lower edge of the liquid outlet head sleeve 12 abuts against the bottom corner 24 to form a closed space, so that a double-layer seal is formed outside the liquid outlet head 11, and air is isolated. The lower edge of the liquid outlet head sleeve 12 is an elastic outer edge 25, which is preferably soft rubber, and when the cap 3 is clamped on the bottle cap body 2, the elastic outer edge 25 is deformed by extrusion with the bottom corner 24, and the sealing property is improved through elastic deformation. In this way, a double-layer seal is formed at the liquid outlet hole 13, air is well isolated, the risk of spilling is reduced, and the nursing liquid is prevented from being in contact with air to cause deterioration.

[0033] The side of the cap 3 away from the bottle cap body 2 is provided with a contraction wall 16, and the contraction wall 16 is located on the inner side of the cylindrical surface, and the outer side of the contraction wall 16 is provided with a push-pull surface 17 for thumb pushing and pulling; corresponding to the contraction wall 16, the bottle cap body 2 is provided with a notched wall 21 located on the inner side of the cylindrical outer wall of the bottle cap body 2; on the outer side of the notched wall 21, the top of the bottle cap body 2 is thinned to form a notch 22; in this way, elastic deformation is generated, and the cap 3 can be tightly clamped on the bottle cap body 2.

[0034] The material of the nursing liquid bottle can be HDPE, PET or PP.

[0035] The bottle mouth is designed as double steps, i.e., step one and step two, while the sealing property and appearance of the product are considered, and the improvement can fix the container through the mechanical clamp during the filling production, and then the container is transferred, so that the time for replacing the mold is greatly reduced, and the production efficiency is improved.

[0036] Firstly, the mechanical hand of the filling process is clamped at step one, and when the sealing process is entered, the mechanical hand of the sealing process is clamped at step two, at this time, the mechanical hand of the filling process is loosened from step one, so that the container is easily transferred between the two processes, and the operation is more simple and convenient; at the same time, the conversion of different filling containers no longer needs to replace the mold, so that the time for replacing the mold is greatly reduced, and the production efficiency is improved; in the prior art, the clamp is clamped at the bottle body, in order to adapt to bottles of different shapes and specifications, the mold needs to be replaced, thereby causing downtime.

[0037] Example 2

[0038] As Figure 9 , 10As shown, the difference between the embodiment 2 and the embodiment 1 is that the bottle body of the embodiment 2 is a square bottle, and the transition step 23 is arranged between the step two 20 and the bottle body 1.

[0039] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing detailed description of the present application has been made with reference to the foregoing embodiments, for those skilled in the art, it still can be modified, or part of the technical features of the equivalent replacement. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application, shall be included within the scope of the present application.
