The utility model discloses technical scheme: a metal composite top cover for a milk powder can comprises a skirt and a top cover, and is characterized in that the skirt comprises a skirt ring sleeved on the top edge of a can body and a stepped waist ring positioned above the skirt ring; the waist-contracting ring is provided with a pivot clamping seat, the top cover is provided with a pivot hole corresponding to the pivot clamping seat, the pivot hole is formed by the edge curl of the end edge of the top cover part, and the top cover and the pivot clamping seat on the waist-contracting ring are connected through a pivot to form a flip structure; a plurality of inward bulges or grooves which are distributed at equal intervals are arranged on the skirt pendulum ring along the circumference of the skirt pendulum ring, and a plurality of outward pits or bulges which are distributed at equal intervals are arranged on the circumference of the outer wall of the top edge of the can body and matched with the bulges or grooves.

In the metal composite top cover for the milk powder can, the side of the waist-closing ring opposite to the pivot clamping seat is provided with the lock box convex position, and the corresponding position of the top cover is provided with the lock box concave position.

The top of the top edge of the tank body is abutted against the bottom surface of the step between the skirt hem ring and the waist ring.

The metal composite top cover for the milk powder can is characterized in that a sealing ring is arranged on the bottom surface of a step between the skirt pendulum ring and the waist ring.

The metal composite top cover for the milk powder tank is a concave-convex alternating curved surface.

The utility model relates to a metal system composite top cap for milk powder jar utilizes skirt pendulum ring lock on one's body, utilizes the skirt pendulum ring and receive protruding or recess on the arch between the waist ring and the skirt pendulum ring and the pit or the protrusion cooperation on the outer wall of can body apical margin make metal system composite top cap and can body zonulae occludens guarantee the leakproofness between metal system composite top cap and the can body. Simultaneously contrast traditional plastics material composite top cap, but metal material composite top cap has compromise the food security characteristic that no harmful gas spills over, no harmful substance is appeared and recoverable cyclic utilization's environmental protection characteristic, can guarantee the safety of the interior food of can body better.

Detailed Description

The present invention will be described in further detail with reference to the following examples and accompanying drawings.

Referring to fig. 1, 2, 3, 4 and 5, an embodiment of the present invention is shown in a metal composite top cover for a milk powder can. The iron composite top cover comprises a skirt base 1 and a top cover 2, wherein the skirt base 1 comprises a skirt hem ring 11 sleeved on the top edge of the can body and a waist-tightening ring 12 positioned above the skirt hem ring 11; a step 13 is arranged between the skirt hem ring 11 and the waist contracting ring 12. The waist ring 12 is provided with a pivot clamping seat 121, the top cover 2 is provided with a pivot hole 21 corresponding to the pivot clamping seat 121, the pivot hole 21 is formed by the edge curl of the end edge of the top cover part, and the top cover 2 and the pivot clamping seat 121 on the waist ring 12 are connected through a pivot 3 to form a flip structure; a plurality of inward bulges 111 which are distributed at equal intervals are arranged on the skirt pendulum ring 11 along the circumference of the skirt pendulum ring 11, and a plurality of outward pits which are distributed at equal intervals are arranged on the circumference of the outer wall of the top edge of the can body and matched with the bulges 111. Of course, a plurality of inward grooves which are distributed at equal intervals are arranged on the skirt pendulum ring 11 along the circumference of the skirt pendulum ring 11, and a plurality of outward bulges which are distributed at equal intervals are arranged on the circumference of the outer wall of the top edge of the can body and matched with the grooves. The top of the top edge of the can body is abutted against the bottom surface of the step 13 between the skirt hem ring 11 and the waist ring 12. So when the compound top cap lock of metal system was on one's body, several inward protruding 111 card was gone up to skirt pendulum ring 11 was gone into the outside pit of several on the outer wall of can body apical margin for the compound top cap of metal system closely locks in can body apical margin, and also make the top of can body apical margin tightly support and lean on in the 13 bottom surfaces of step between skirt pendulum ring 11 and receipts waist ring 12, two kinds of structures that correlate like this make the compound top cap of iron more closely lock in can body, make the leakproofness between compound top cap of metal system and the can body strengthen greatly. In a further mode, a sealing ring is arranged on the bottom surface of a step 13 between the skirt hem ring 11 and the waist contracting ring 12, so that the sealing property between the metal composite top cover and the can body is enhanced. A lock box convex position 122 is arranged on one side of the waist ring 12 opposite to the pivot clamping seat 121, and a lock box concave position 22 is arranged at the corresponding position of the top cover 2, so that the skirt 1 and the top cover 2 can be locked, and the sealing performance between the top cover 2 and the skirt 1 is ensured. The metal composite top cover is especially a tinplate composite top cover.

In a further mode, the shape of the top cover 2 can be a curved surface with alternate concave surfaces 23 and convex surfaces 24, and the mode can increase the hand-held force so as to ensure that the metal composite top cover is buckled on the can body more conveniently and quickly or the metal composite top cover is pulled out of the can body.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, many modifications and improvements can be made without departing from the inventive concept, and all of them belong to the protection scope of the present invention.
