Description
TECHNICAL FIELD
[0001] The utility model belongs to the technical field of bottle cap, and specifically relates to an easy-to-tear cap. BACKGROUND
[0002] As an important component of packaging containers, the main function of a bottle cap is to close the bottle mouth, prevent the leakage of contents, and protect the contents from external pollution. With the increasing requirements of consumers on product quality and safety, the sealing performance and ease of use of a bottle cap become key indicators for measuring its quality.
[0003] Most of the common bottle cap designs on the market adopt the way of one layer of inner sealing and one layer of top sealing. Although this design can close the bottle mouth to a certain extent, the sealing performance is relatively poor, and it is difficult to effectively prevent the penetration of gas, liquid or small particles, thereby affecting the shelf life and quality of products. In addition, in order to facilitate consumers to tear and open, the existing bottle caps on the market are often designed with small notches at the tear opening. Although this design improves the ease of use of the bottle cap to a certain extent, the existence of the notches destroys the integrity of the bottle cap, not only affects the appearance of the product, but also may cause fragments or damage during use, which poses a potential threat to the safety of consumers. SUMMARY
[0004] In order to solve the above problems, the utility model provides an easy-to-tear cap.
[0005] The technical scheme adopted by the utility model is as follows: the utility model provides an easy-to-tear cap, which comprises a bottle cap, a bottle mouth inner ring is arranged at the lower end of the bottle cap, an outer sealing layer is arranged at the lower end of the periphery of the bottle cap, a tear groove is arranged on the inner side wall of the outer sealing layer, and a tear strip is arranged at the lower end of the outer sealing layer.
[0006] Further, a bottle mouth inner sealing protrusion one is arranged at the lower end of the outer side wall of the bottle mouth inner ring, and a bottle mouth inner sealing protrusion two is arranged at the upper end of the outer side wall of the bottle mouth inner ring.
[0007] Further, a top layer sealing ring is arranged at the inner top end of the bottle cap, and the top layer sealing ring is arranged outside the bottle mouth inner ring.
[0008] Further, a bottle mouth outer sealing protrusion is arranged on the inner side wall of the outer sealing layer.
[0009] Further, the shape of the tear groove is a sharp corner structure.
[0010] Further, the bottle cap is made of PE material.
[0011] The utility model has the beneficial effects as follows by adopting the above structure:
[0012] (1) By setting the bottle mouth inner sealing protrusion one, the bottle mouth outer sealing protrusion, the top layer sealing ring and the bottle mouth inner sealing protrusion two, four layers of sealing structure, greatly enhance the sealing effect of the bottle cap, effectively prevent the product leakage.
[0013] (2) The user only needs to pull up the tear strip with fingers, and gradually tears along the edge of the bottle cap, so that the bottle cap can be easily opened, and the operation is simple and fast.
[0014] (3) The sharp angle-shaped tear groove design makes the tearing process more smooth, and reduces the operation difficulty of the user.
[0015] (4) During the tearing process, the bottle cap itself has no gap, the integrity of the bottle cap is maintained, the fragments or damage caused by tearing are avoided, and the overall appearance and safety of the product are improved.
[0016] (5) The bottle mouth inner sealing protrusion one, the bottle mouth outer sealing protrusion, the top layer sealing ring and the bottle mouth inner sealing protrusion two, four layers of sealing structure not only prevent the product leakage, but also better isolate the bacteria in the air, and ensure the hygiene and safety of the product.
