Referring to fig. 1 to 6, the present embodiment provides a 407# oblong full-open pop-top cover, which includes: a cover surface 1 and a pull ring 2 riveted on the top surface of the cover surface 1; the edge of the cover surface 1 is provided with an annular dividing line 11 near the edge, the annular dividing line 11 is also provided with an upward extending curled edge, and the curled edge is used for being sealed with a tank opening flanging of the tank body by a special tank sealing machine; the inner side wall 13 of the bead is of a cross-section that gradually expands outwardly from the bottom to the top. The inner side wall 13 which gradually expands outwards from the bottom to the top is used for avoiding packaging food, so that the food can not damage the edge of the food when being poured out, and the integrity of the food is ensured.

Wherein, the cover surface 1 comprises: a rectangular part, a small semicircular part extending outwards from one opposite side of the rectangular part, namely the cover surface 1 is in a rounded rectangle shape.

The radius of the small semicircular part is 40+/-2 mm, the length of the short side of the rectangular part is 80+/-4 mm, and the length of the long side of the rectangular part is determined according to actual needs.

This open easy-open lid is through the capping 1 design into the fillet rectangle shape with the cover, and pull ring 2 rivets in fillet rectangle's minor face position, when tearing the cover through pull ring 2, the required strength of tearing on the long limit of being parallel relatively is even, easily tears, and user experience is better. The traditional oval can cover is torn from the short side, and the score line is from the short side to the middle part of the long side, so that the traditional oval can cover can be torn with more and more strength, is not friendly to users and has poor use experience.

The annular score line 11 is located at a portion below the tab 2, that is, the score line portion with the greater depth is easy to be torn, the tab body outside the rivet joint 21 of the tab 2 is provided with an annular notch 22, and the tip 23 of the tab 2 is located directly above the annular score line. When the cover is opened, the main body of the pull ring 2 is firstly bent upwards, and then the corresponding annular dividing line part is pierced by the tip 23 for pressure relief; the tab 2 continues to be pulled up so that the lid surface 1 is completely torn open.

Specifically, the cover 1 includes: the main cover surface 10, by the turn-up that the edge of main cover surface 10 extends, still be equipped with a plurality of strengthening rib grooves 12 on the main cover surface 10, in this embodiment, the strengthening rib groove 12 is a plurality of groove structures of concave locating main cover surface 10 middle part.

As shown in fig. 6, the crimp includes: an inner side wall 13 bent upwardly from the edge of the main lid surface 10, a top wall 14 extending horizontally outwardly from the edge of the inner side wall 13, and an outer curl 15 curled downwardly from the edge of the top wall 14.

The cross section of the junction of the main cover surface 10 and the inner side wall 13 forms a first arc shape, and the arc radius R1 of the first arc shape is 1.2mm.

The cross section of the junction of the inner side wall 13 and the top wall 14 is in a second arc shape, and the arc radius R2 of the second arc shape is 0.5mm.

The cross section of the outer bead 15 forms a third arc shape with an arc radius R3 of 1.1mm.

Further, in the present embodiment, the vertical height of the inner sidewall 3 is 4mm. The top wall 14 has a horizontal width of 5mm. The vertical height of the outer bead 15 is 2.2mm and the lateral width is 1.1mm. The cross section of the top wall 14 has a fourth arc shape with an arc radius R4 of 8mm.

Wherein, the angle of the outward expansion of the cross section of the inner side wall 13 is 4 degrees, namely the cross section forms an included angle of 4 degrees with the vertical direction.

Referring to fig. 7 again, the present embodiment further provides a two-piece stretching can 100, which includes a can 3 and the 407# oblong fully-open easy-open lid 1 according to any one of the above described embodiments that is covered on the can 3.

In the 407# long oval fully-open easy-open cover and two stretching can bodies thereof in the embodiment, the main body part of the cover surface 1 is rectangular, a semicircular part extends out of one opposite short side of the rectangular part, the opening corresponding to the can body 3 is matched with the cover surface 1, and the cover surface 1 and the two stretching can bodies 100 of the cover surface 1 are attractive in appearance. Wherein the radius R5 of the semicircle-shaped part is 40+/-1 mm.

According to the 407# long oval full-open easy-open cover and the two-piece stretching tank body thereof, the inner side wall 13 of the curled edge is designed to be in an outward expansion extension shape, and the torn annular score line 11 is arranged in the inner part, so that after the cover is opened, the edge profile of the opening edge of the cover is larger than the outer edge profile of the inner food material, and the food material can be conveniently and completely poured out from the opening. And the capping of cover designs to the right-angled rectangle shape, and when opening the jar, tears the cover along the line of marking, and required strength is even, and the use is experienced better.

The foregoing examples are provided to further illustrate the technical contents of the present utility model for the convenience of the reader, but are not intended to limit the embodiments of the present utility model thereto, and any technical extension or re-creation according to the present utility model is protected by the present utility model. The protection scope of the utility model is subject to the claims.
