in the drawings, the reference numbers: 1. a bottle cap body; 2. a water outlet; 3. sealing the top sheet; 4. an outer ring portion; 5. an inner ring portion; 6. reinforcing the connection points; 7. installing threads; 8. anti-skid stripes; 9. a retaining ring.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-4, the novel plastic bottle cap includes a cap body 1; a water outlet 2 is arranged on the bottle cap body 1, a sealing top plate 3 is arranged at the water outlet 2, and the thickness of the sealing top plate 3 is 0.1-0.5 mm; the bottle cap body 1 comprises an outer ring part 4 and an inner ring part 5, the water outlet 2 is arranged on the inner ring part 5, and the sealing top plate 3 is arranged at one end of the inner ring part, which is close to the inner side of the bottle cap body 1; the thickness of the sealing top sheet 3 is reduced to 0.1-0.5mm through rotary cutting; sealed top flat 3 leaves with the junction of inner ring part 5 and strengthens tie point 6, when carrying out secondary cross cutting, leaves and does not do the cutting a bit, makes sealed top flat 3 broken and not fall through strengthening tie point 6, avoids falling into the aquatic, outer loop part 4's inboard is provided with mounting thread 7, convenient and bottle threaded mounting, outer loop part 4's the outside is provided with anti-skidding stripe 8, is convenient for adorn bottle lid body 1 soon through anti-skidding stripe 8, bottle lid body 1's inboard top be provided with bottleneck complex holding ring 9, play the effect of further location through inside holding ring 9, guarantee the effective cooperation of bottle lid body 1 and bottle.

When in use, the thickness of the sealing top plate 3 of the bottle cap can not be processed to be less than 0.5mm by the injection molding process at present, if the thickness of the sealing top plate 3 of the bottle cap formed by one-time injection molding is less than 0.5mm, the defective rate of the bottle cap can be greatly increased, the sealing top plate 3 at the inner side of the bottle cap can be thinned by the die cutting process after one-time injection molding, the thickness of the sealing top plate 3 can be processed to be 0.1-0.5mm, so that the top breaking force of the sealing top plate 3 is small and stable, the top breaking force of the sealing top plate 3 can be controlled to be about 100N, the force can push the sealing top plate 3 open by fingers, and the sealing top plate 3 can play a good sealing effect at ordinary times, the sealing top plate 3 is arranged at the bottom of the inner ring part 5, the sealing top plate 3 can not be pushed open by internal force, the sealing property is ensured, and the sealing top plate 3 can be pushed open only by external force, convenient to use improves the use reliability.

It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.
