Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
Example 1
As shown in fig. 1-2, the oral liquid packaging bottle cap in the present embodiment includes a plastic outer cap 1, an aluminum cap 2 and a rubber inner cap 3, wherein the aluminum cap 2 is composed of an aluminum top plate 21 and an aluminum side surrounding plate 22, a through hole 23 is formed in the center of the aluminum top plate 21, the aluminum cap 2 is installed in the inner cavity of the plastic outer cap 1, and the rubber inner cap 3 is installed in the inner cavity of the aluminum cap 2; the top surface of the inner cavity of the plastic outer cover 1 is provided with a convex column 11, the lower end of the convex column 11 is provided with a convex ring 12, the diameter of the convex ring 12 is larger than that of the through hole 23, the convex column 11 is positioned in the through hole 23, the aluminum top plate 21 comprises an annular aluminum top plate main body 211 and an easy-tearing ring 212, the easy-tearing ring 212 surrounds the through hole 23, and the convex ring 12 is positioned below the through hole 23 and is in contact with the lower surface of the easy-tearing ring 212.
The outer edge of the easy-to-tear ring 212 is connected with the inner edge of the annular aluminum top plate main body 211 through a plurality of connecting points 213, the connecting points 213 are arranged along the circumferential direction of the easy-to-tear ring 212, and a breaking line 214 for separating the easy-to-tear ring 212 from the annular aluminum top plate main body 211 is arranged between two adjacent connecting points 213. When the plastic outer cover 1 is manually opened, the connection points 213 are broken, and the easy-to-tear ring 212 is separated from the annular aluminum top plate body 211.
A plurality of reinforcing ribs 2111 are arranged on the annular aluminum top plate main body 211, and the reinforcing ribs 2111 and the aluminum cover 2 are formed through integral punch forming. When the easy-tear ring 212 is torn, the annular aluminum ceiling main body 211 is locally reinforced by the respective reinforcing ribs 2111, and the annular aluminum ceiling main body 211 can be better prevented from being deformed.
The number of the reinforcing ribs 2111 is plural, and the reinforcing ribs 2111 are arranged along the circumferential direction of the easy-tear ring 212. When the strengthening rib 2111 has many circles, two strengthening ribs 2111 between two adjacent circles of strengthening ribs 2111 have two distribution modes: the first is that two reinforcing ribs 2111 adjacent to each other in front and back are aligned and distributed, and are arranged neatly and not staggered; the second is that two reinforcing ribs 2111 adjacent to each other in the front and back are distributed in a staggered manner, that is, a gap is formed between two reinforcing ribs 2111 in the same ring of reinforcing ribs 2111, and the adjacent reinforcing rib 2111 in the other ring of reinforcing ribs 2111 corresponds to the gap.
The upper surface of the rubber inner cover 3 is provided with a positioning groove 31, and the positioning groove 31 is positioned in the projection area of the easy-to-tear ring 212 in the vertical projection plane. The positioning groove 31 is arranged on the upper surface of the rubber inner cap 3, so that the thickness of the rubber inner cap 3 at the position of the positioning groove 31 is thinner, and when a straw is inserted, the straw can easily pierce through the rubber inner plug and extend into the glass bottle body.
Four salient points 32 are arranged on the upper surface of the rubber inner cover 3, and the salient points 32 are positioned on the periphery of the positioning groove 31. When the rubber inner cover 3 is installed in the inner cavity of the aluminum cover 2, the salient points 32 on the upper surface of the rubber inner cover 3 can abut against the position where the annular aluminum top plate main body 211 is located, and a good supporting effect is achieved.
When a user wants to take the oral liquid, the plastic outer cover 1 is broken off by hand, at the moment, the easy-to-tear ring 212 is separated from the annular aluminum top plate main body 211 under the action of the convex ring 12, so that the plastic outer shell is separated from the aluminum cover 2, the rubber inner cover 3 is exposed on the top surface of the aluminum cover 2, and a straw is inserted into the bottle body from the rubber inner cover 3, so that the oral liquid can be taken. Because the easily torn ring 212 is easily separated from the annular aluminum top plate main body 211, after the plastic outer cover 1 is broken off, the annular aluminum top plate main body 211 basically cannot deform and can keep flat, the occurrence of protrusion, breakage or burrs is effectively avoided, the lips or fingers of a user are prevented from being scratched, and the safety of the user when the user takes the oral liquid is improved. In addition, after the plastic outer cover 1 is broken off, the annular aluminum top plate main body 211 can press the rubber inner cover 3, so that the sealing performance between the rubber inner cover 3 and the bottle opening of the bottle body is ensured, and the leakage of the oral liquid is avoided.
