Detailed Description

The invention will be further explained by means of specific embodiments with reference to the drawings, in which:

referring to fig. 1, an embodiment of an easily opened aluminum-plastic combined cover includes an aluminum cover 1 and a plastic cover 2 connected to the aluminum cover 1, a central via hole is formed in the aluminum cover 1, the plastic cover 2 has a lower convex portion 21, the lower convex portion 21 penetrates through the central via hole and the lower convex portion 21 has a fitting portion abutting against the lower surface of the aluminum cover 1, the plastic cover 2 is rotatable relative to the aluminum cover 1, and the foregoing arrangement is substantially consistent with the existing aluminum-plastic combined cover and is not repeated. On the basis of the scheme, one annular cutting part 3 is arranged on the side wall of the plastic cover 2 (two annular cutting parts 3 can be arranged, the two annular cutting parts 3 are opposite to each other on the side wall of the plastic cover 2, as shown in fig. 2, although the aluminum cover 1 is easier to cut, the arrangement cost is relatively increased, and one annular cutting part 3 can sufficiently deal with the situation that the aluminum cover 1 is thinner in thickness, lower in hardness and the like under the common situation), and the annular cutting part 3 is used for extruding and cutting the side wall of the aluminum cover 1 in the process of rotating the plastic cover 2.

Specifically, the circular cutting component 3 comprises a cutting blade 31 and a pressing block 32, the cutting blade 31 penetrates through the side wall of the plastic cover 2, the head end of the cutting blade 31 is located on the inner side of the side wall of the plastic cover 2, the tail end of the cutting blade 31 is located on the outer side of the side wall of the plastic cover 2 and is fixedly connected with the pressing block 32, and the pressing block 32 is fixedly connected with the outer surface of the side wall of the plastic cover 2. The cutting blade 31 is a metal blade and the pressing block 32 is still a plastic block. Because it is rotatable to mould lid 2, the user can press according to the briquetting 32 with the finger (the material of moulding lid 2 itself is softer, is enough to press), and rotate simultaneously and mould lid 2, cutting blade 31 atress extrusion aluminium lid 2's lateral wall, and the follow-up cuts circularly simultaneously, until the lateral wall of aluminium lid 2 upper and lower one-tenth two, can easily will mould lid 2 and remove together with upper half aluminium lid 1.

Further, a circle of guide grooves 12 are formed in the outer surface of the side wall of the aluminum cap 1, and the guide grooves 12 are used for guiding the cutting blade 31 to cut. The section of the guide groove 12 is in a V shape, and the cutting blade 31 can be more accurately and stably guided to be circularly cut along the track line.

Further, the inner surface of the side wall of the aluminum cap 1 is provided with a preset nick, and the preset nick corresponds to and is consistent with the track of the guide groove 12. The predetermined score corresponds to the back of the guide groove 12 and is opposite thereto, so that the aluminum lid 1 can be cut more easily and accurately.

In addition, to provide a more comfortable pressing experience, the outer surface of the pressing block 32 is a raised convex surface 321, as shown in fig. 3; alternatively, the outer surface of the pressing block 32 is provided with a groove 322 for facilitating the pressing of the finger, which is illustrated in fig. 1 and 2.
