Abstract

The utility model relates to an easy-open lid, in particular to a pressure-resistant easy-open lid. The pressure-resistant easy-open lid comprises a lid body (1), an opening tongue piece (2) and a pull ring (3). A finger groove (4) is formed in the lid body (1), a wire mark (6) is arranged on the lid body (1), the opening tongue piece (2) is formed by machining a cutting line (5) on the lid body, and the pull ring (3) and the lid body (1) are connected through a rivet (7) at the planar center of the lid body (1). By arranging a reinforcing arch (8) recessed downwards along the plane of the lid body near the cutting line of the lid body, the strength of the portion near the cutting line is greatly improved, deformation of the portion near the cutting line can be effectively avoided, and customers are prevented from being hurt due to the fact that the opening tongue piece (2) and the content fly off.

Description

The easy-to-draw lid of a kind of pressure resistant type

Technical field

The utility model relates to a kind of easy-to-draw lid, the easy-to-draw lid of especially a kind of pressure resistant type.

Background technology

The normal employing of at present common easy-to-draw lid shape and structure shown in Figure 1; comprise and cover body 1, unlatching tongue piece 2, draw ring 3; lid body 1 is provided with finger groove 4 and wire size 6; opening tongue piece 2 is by forming at lid body 1 processing line of weakness 5; draw ring 3 is connected by being positioned at the rivet 7 that covers the body plane center with lid body 1; because canned pressure changes or environmental concerns; the capping metaboly appears in regular meeting; and deformation position is unfixing; in the time of near distortion appears at tangent line; easily cause tangent line integral body and pop, product tongue piece and content fly off, and injure the customer easily.Easy-to-draw lid as shown in Figure 2 once appearred in market, Taiwan, the direction of finger groove 4 is processed into the direction opposite with Fig. 1, control compressive resistance by finger groove wedge angle and the distance at lid body 1 edge, namely reach in this point deformation by the intensity that weakens the finger groove sharp corner, thereby avoid near tangent line, being out of shape, though this easy-to-draw lid can prevent that capping is out of shape near tangent line, can reduce the whole withstand voltage level that covers body.

The utility model content

For overcoming above-mentioned shortcoming, the utility model arranges one and strengthens arch near lid body tangent line, increased near the intensity of tangent line effectively, thereby avoided this region deformation, prevents that tangent line integral body from popping, and realizes the fixed point distortion by the whole withstand voltage level of strengthening lid.

The utility model is achieved in that the easy-to-draw lid of a kind of pressure resistant type, comprise cover body, open tongue piece, the Pull ring cover body is provided with finger groove and wire size, open tongue piece by forming at lid body processing line of weakness, draw ring is connected by being positioned at the rivet that covers the body plane center with the lid body, near lid body tangent line, be provided with a reinforcement arch recessed along the lid plane, it is parallel with lid body tangent line that this strengthens arch, width range is 0.5-0.9mm, depth range is 0.05-0.09mm, is 94 °-98 ° in the radian scope of covering circular arc that body plane forms.

The utility model has increased near the intensity of tangent line greatly by at lid body tangent line position a reinforcement arch being set, and can effectively avoid near the distortion of tangent line, and then avoid tongue piece and content to fly off, and injures the customer.

Fig. 1 is the planar view of the present easy-to-draw lid that generally adopts;

Fig. 2 is the planar view of the easy-to-draw lid of market, Taiwan appearance;

Fig. 3 is the planar view of the designed easy-to-draw lid of the utility model.

The specific embodiment

As shown in Figure 3, the related easy-to-draw lid of the utility model, comprise and cover body 1, open tongue piece 2, draw ring 3, lid body 1 is provided with finger groove 4 and wire size 6, opening tongue piece 2 is by forming at lid body 1 processing line of weakness 5, draw ring 3 is connected by being positioned at the rivet 7 that covers body 1 planar central with lid body 1, by mould up and down to covering the direct extruding of this dignity, make material production plastic deformation, near lid body tangent line, be shaped one along the recessed reinforcement arch 8 of lid body plane, thereby strengthen the intensity at tangent line position, avoid this region deformation, it is parallel with lid body tangent line that this strengthens arch 8, and width range is 0.5-0.9mm, depth range is 0.05-0.09mm, is 94 °-98 ° in the radian scope of covering circular arc that body plane forms.
