Detailed Description

The technical solutions of the present utility model are further described in detail below with reference to the accompanying drawings and specific embodiments, and the parts of the present utility model which are not specifically described and disclosed in the following embodiments should be understood as the prior art known or should be known to those skilled in the art.

As shown in fig. 1 and 2, the utility model discloses a backflow prevention bottle body, which comprises a bottle body 1 and a bottle neck which are integrally formed, wherein the bottle neck comprises a large-diameter part 6 and a small-diameter part 3, the lower end of the large-diameter part 6 is connected with the bottle body 1, and the upper end is connected with the small-diameter part 3.

The upper part of the bottle body 1 is provided with a bottle shoulder 7, and the large diameter part 6 of the bottle neck is connected to the bottle body 1 and is positioned above the bottle shoulder 7. The whole outline of big footpath portion 6 and path portion 3 is straight barrel type, and wherein the outer port of path portion 3 is the flaring bottleneck that expands outward, and the terminal surface of flaring bottleneck is provided with bottleneck platform 4.

The bottleneck platform 4 is annular, and an annular groove 5 is formed between the bottleneck platform 4 and the outer wall of the small-diameter part 3 and the end face of the large-diameter part 6. When the bottle body is adjusted to enable the fluid in the bottle to flow out, the bottle body needs to be adjusted to be in an inclined or horizontal state from a vertical state, the opening edge of the horn-shaped bottle opening is lower than the straight cylinder part of the small-diameter part 3, and the fluid flows out of the bottle body along with the opening edge, so that the fluid can be prevented from flowing back; after the fluid is poured out, when the bottle body is adjusted to be in a vertical state, the fluid in the straight cylinder part of the small-diameter part 3 flows back into the bottle body, and the fluid at the horn-shaped opening can continuously flow out of the bottle from the lower opening edge, so that the backflow phenomenon is avoided.

The material of bottle is PET or PE to through annotating blow, crowding blow or annotating stretch blow shaping, the material of selecting is common material and easily obtains, annotates and blows, crowding blow or annotate stretch blow etc. shaping technology can guarantee that the bottle has stable quality.

As shown in fig. 3 and 4, the utility model also discloses a backflow prevention packaging bottle, which comprises a bottle cap 10 and the bottle body, wherein the bottle cap 8 is connected with the bottle body through threads.

The outer wall of the large diameter part 6 of the bottle neck is provided with an external thread 2, the inner wall of the bottle cap 8 is provided with an internal thread matched with the external thread 2, and the bottle cap 8 is rotated so as to realize the lifting or lowering of the bottle cap 8 relative to the bottle body, thereby achieving the purpose of opening or sealing the bottle mouth. The screw thread rotary opening type sealing is adopted, and the bottle cap 8 and the bottle body can be separated simply and conveniently after finished product packaging is used, so that the garbage classification in the later period is convenient.

The external thread 2 arranged on the large diameter part 6 has a diameter larger than the maximum diameter of the external port of the small diameter part 3, and the external thread 2 is matched with the internal thread on the inner wall of the bottle cap 8 for use, namely, the diameter of the internal thread is also larger than the maximum diameter of the trumpet-shaped bottle mouth, so that the interference of the trumpet-shaped bottle mouth to the closing process of the bottle cap 8 is avoided.

When the bottle cap 8 is covered on the bottle body, the bottle opening platform 4 can be abutted against the inner side of the bottle cap 8, so that the bottle cap 8 and the bottle body are sealed.

In order to enhance the sealing effect of the bottle body and the bottle cap 8, a gasket (not shown in the figure) is arranged in the bottle cap 8, and the diameter of the gasket is smaller than the inner diameter of the bottle cap 8 and larger than the outer diameter of the annular bottle opening platform 4. When the packaging bottle is covered, the bottle opening platform 4 is firstly abutted against the gasket, and then is abutted against the inner side of the bottle cover 8. The gasket can be fixedly arranged in the bottle cap 8, for example, by bonding, scalding or electromagnetic induction heat sealing, and can also be directly and movably arranged in the bottle cap 8, and only the gasket can cover the whole bottle mouth platform 4 during the covering process.

The aluminum foil used for sealing the bottle mouth is arranged on the horn-shaped bottle mouth, the sealing effect can be further enhanced by the aluminum foil seal, and liquid in the packaging bottle is prevented from leaking from the bottle mouth. In order to facilitate the opening of the aluminum foil, an annular positioning ring and a spike for puncturing the aluminum foil are also arranged outside the bottle cap 8. When the aluminum foil is required to be pierced, the bottle cap 8 is firstly taken down from the bottle body, the bottle cap 8 is turned over and pressed above the bottle mouth, the sharp part on the bottle cap 8 pierces the aluminum foil, and the aluminum foil can be pierced and cut in a ring shape by rotating the bottle cap 8.

The bottle lid 8 outer wall is provided with anti-skidding tooth 9, and anti-skidding tooth 9 is the vertical sand grip of following bottle lid 8 outer wall circumference interval distribution, and the frictional force when the setting of anti-skidding tooth 9 can increase rotatory bottle lid 8 uses with the cooperation of the seal of screw thread swing formula, more easily opens or twists tight bottle lid 8.

In the utility model, the material of the bottle cap 8 is PP or PE, and the bottle cap 8 is formed by injection molding.

The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the utility model.
