Description

Easy-to-open bottle cap of packaging bottle

Technical Field

The invention relates to the technical field of packaging containers, in particular to a packaging bottle cap with an easy-opening.

Background

At present, aluminum bottle caps are widely applied to packaging bottles of food, medicines, health care products, chemicals and the like, and hundreds of billions of preparations are produced in China every year. However, almost all preparations on the market at present need to be matched with a bottle stopper and a metal cover to realize sealed packaging, and auxiliary tools such as a straw and the like are needed during use, so that the processing cost is high, and a large amount of plastic waste is generated; meanwhile, the bottle cap is time-consuming and labor-consuming to open, the bottle cap is difficult to open without a straw, the use is inconvenient, and a large amount of manpower and material resources and equipment investment are consumed for producing a large amount of plastic straws, so that the resource waste is also caused.

The aluminum bottle cap in the prior art generally comprises a plastic outer cap, an aluminum cap and a rubber inner cap, wherein the aluminum cap consists of an aluminum top plate and an aluminum side surrounding plate, and a through hole is formed in the center of the aluminum top plate; the aluminum cover is arranged in the inner cavity of the plastic outer cover, and the rubber inner cover is arranged in the inner cavity of the aluminum cover; the top surface of the inner cavity of the plastic outer cover is provided with a convex column, the lower end of the convex column is provided with a convex ring, the diameter of the convex ring is larger than that of the through hole, the convex column is arranged in the through hole, and the convex ring is arranged below the through hole (the convex ring is usually contacted with the lower surface of the aluminum top plate). The aluminum cover is connected with the plastic outer cover in a hot riveting forming mode (a convex ring is formed at the lower end of the convex column through hot riveting). When the bottle cap is to be installed on the bottle mouth of the glass bottle body, the rubber inner cap is covered on the bottle mouth, and then the lower edge of the aluminum side covering plate is buckled and pressed by buckling and pressing equipment to form a covering edge, so that the aluminum cap covers the periphery of the bottle mouth and the rubber inner cap.

When a user wants to take the preparation, the plastic outer cover is broken off by hand, the convex ring is separated upwards from the through hole, the plastic outer shell is disconnected with the aluminum cover, the rubber inner cover is exposed on the top surface of the aluminum cover, and the suction tube is inserted into the bottle body from the rubber inner cover, so that the preparation can be taken. Because the diameter of the convex ring is larger than that of the through hole, when the convex ring is pulled out upwards from the through hole, the part of the aluminum top plate at the edge of the through hole is pulled up to form a bulge, even a crack or a burr appears, the position of the bulge, the crack or the burr is around the position of inserting the straw, and when a user takes the preparation, the lips or fingers of the user are easily scratched.

Therefore, in order to solve the above problems, there is a need for an easy-to-open bottle cap for a packaging bottle, which can be opened directly to drink a preparation in the packaging bottle without using auxiliary tools such as a plastic straw, and can well avoid the problem of easy scratching of a handle when an aluminum cap is opened, and has a simple overall structure and convenient and safe use.

Disclosure of Invention

In view of the above, the invention aims to overcome the defects in the prior art, and provides an easy-to-open bottle cap for a packaging bottle, which can be directly opened to drink a preparation in the packaging bottle without using auxiliary tools such as a plastic straw and the like, can well avoid the problem that a handle is easy to scratch when an aluminum cap is opened, and has a simple overall structure and convenient and safe use.

The easy-opening packaging bottle cap comprises an outer cap, an aluminum cap and a sealing gasket, wherein the aluminum cap is arranged in an inner cavity of the outer cap, the sealing gasket is arranged in the inner cavity of the aluminum cap and is attached and sealed with a bottle opening, the aluminum cap is composed of a top plate and a side wall, a tearing opening is formed in the top plate, two penetrating cutting lines are formed between the tearing opening and the side wall edge to divide the aluminum cap into a first tearing surface and a second tearing surface, and the first tearing surface part is fixedly connected with the outer cap.

Furthermore, a through hole is formed in the first tearing surface, a convex column is arranged on the top surface of the inner cavity of the outer cover in a shape-fitting manner relative to the through hole, a boss is formed at the lower end of the convex column and is located in the through hole, the cross section of the convex column is smaller than that of the through hole, the convex column is limited in the through hole by the boss, and the same bottle cap opening effect can be achieved by fixedly connecting the hole in the outer cover with the first tearing surface, so that the detailed description is omitted.

Further, two the line of carving absolutely parallel just the first area of tearing the face is less than the second area of tearing the face, the line of carving absolutely that is parallel to each other is when opening the bottle lid, and it is parted with the first face of tearing and the second of tearing more easily, and is more laborsaving, and certainly in the actual production life, two lines of carving absolutely can set up with other many ways.

Further, it is by to open the tear mouth the boss covers completely, and the boss will open the tear mouth and cover completely and can set the bottle lid and have better leakproofness, according to actual conditions, should open the tear mouth and can be for opening completely or with the easy tear mouth of score broken line intercommunication.

Furthermore, the boss with but circumference is provided with a plurality of dogteeth on the binding face of roof, and the setting of dogtooth can guarantee the good combination of aluminium lid and enclosing cover well, and then guarantees that the bottle lid just too has good leakproofness.

Furthermore, the sealing gasket is circumferentially provided with a concave edge attached to the bottle mouth, and the concave edge matched with the bottle mouth can ensure good sealing between the bottle cap and the bottle body.

Furthermore, the outer cover is made of plastic, the sealing gasket is a rubber gasket, the plastic and the rubber are cheap and easily available materials, the manufacturing cost is low, and the recycling is convenient.

When opening the bottle lid, the user only need break off with the enclosing cover, and the face of tearing that links together with the enclosing cover is along carving the broken line and the face of tearing separately with first, and the mode that covers in the sealed pad outside with incomplete covering at this moment is torn the face and is just peeled off very easily in the second, takes off the second and tears the face, can reveal sealed the pad, the user alright with the thing of direct drinking to adorning inside the bottle.

The invention has the beneficial effects that: according to the bottle cap of the packaging bottle with the easy-opening, disclosed by the invention, the bottle cap can be easily opened by breaking the outer cap, the bottle cap can be directly opened to drink a preparation in the packaging bottle on the premise of not using auxiliary tools such as a plastic straw and the like, the problem that a handle is easy to scratch when an aluminum cap is opened can be well avoided, the whole structure is simple, and the use is convenient and safe.
