Problems solved by technology

[0003] The purpose of the present invention is to solve the problem that the pull ring of the easy open lid in the prior art is easy to loosen and deflect, which causes the relative position of the olecranon tip of the pull ring and the notch to change, resulting in the problem that the easy open lid cannot be opened or is difficult to open. A new type of easy-open lid that can still be opened when the pull ring is loose and its design method, which can still ensure the normal opening of the easy-open lid when the pull ring is loose and deflected at a certain angle

Embodiment 1

[0036] exist figure 1 figure 2 In the shown embodiment 1, a new type of easy-open lid with an opening, the easy-open lid includes a lid body 1 and a pull ring 3 riveted to one side of the lid body through a rivet 2, the lid body is a symmetrical structure, and the rivet The central axis of is located on the symmetrical central plane 12 of the cover, and the grooves are symmetrical with respect to the symmetrical central plane of the cover. The pull ring includes a handle 4 on one side of the rivet and an olecranon 5 on the other side of the rivet. The cover is provided with a groove 6 surrounding the center of the cover. The cross section of the groove is the upper Trapezoidal with a wide bottom and a narrow bottom. The groove is a ring-shaped closed structure formed by connecting four groove segments, including a main segment 7 and an open segment 8 near the olecranon (see image 3 ), the opening section is arc-shaped, the center of the opening section is located on the c...

Embodiment 2

[0039] The groove in Example 2 is a ring-shaped closed structure formed by connecting 6 groove segments. The depth of the 6 groove segments is the same, and the depth is 60% of the thickness of the easy-open lid body, including a main segment and a olecranon. Opening section, the opening section is arc-shaped, the center of the opening section is located on the central axis of the rivet, the two ends of the opening section are connected to an extension section, the extension section is a straight line section, and is arranged on both sides of the opening section. In the tangential direction of the end, the end of the extension section passes through the transition section 11 ( Figure 4 Indicated by a dotted line) is connected to the main section, the transition section is arc-shaped, and the extension section is tangent to one end of the transition section, and the other end of the transition section is smoothly connected to the main section (see Figure 4 ), and the rest are...

Embodiment 3

[0041] The groove depth of the opening section of embodiment 3 is equal to and greater than that of the main section, the groove bottom of the extension section is an inclined structure, and the groove depth of the extension section near the opening section is the same as the groove depth of the opening section. The groove depth of the end of the extension section close to the main section is the same as that of the main section. In this embodiment, the depth of the grooved main section is 55% of the thickness of the easy-open lid body, the depth of the grooved opening section is 1.1 times the depth of the main section, and the rest are the same as in Embodiment 1.

Abstract

The invention discloses an easy opening cover with a novel opening and a design method of the easy opening cover. The easy opening cover includes a cover body and a pull ring. The cover body is provided with a carving groove surrounding the center of the cover body. The carving groove is of a circular structure formed by connecting a plurality of groove sections. The carving groove includes a mainsection and an opening section close to an eagle beak. The opening section is in an arc shape, the circle center of the opening section is located on the central axis of a rivet, the two ends of theopening section are connected with extension sections, and the other ends of the extension sections are connected with the main section. When the pull ring rotates around the central axis of the rivetwithin a certain angle range, the eagle beak on the pull ring is always located above the opening section of the carving groove. The problem that the easy opening cover cannot be opened or is difficult to open because of the change of the relative position of an eagle beak tip of the pull ring and the carving groove due to the fact that the pull ring of the easy opening cover is prone to loosening and deflecting is effectively solved, and the practical value is high.

Description

technical field [0001] The invention relates to the technical field of easy-open lids for packaging containers, in particular to a novel easy-open lid with an opening and a design method thereof. Background technique [0002] In the metal packaging industry, a large number of canned food packaging uses easy-open lid packaging, which greatly facilitates the consumption of canned food, but there are often cases where the ring is dropped, and the olecranon tip of the pull ring bends and cannot pierce the engraved groove, resulting in poor opening. During production, transportation, and storage, the pull ring is bumped and twisted, causing more opening failures after the pull ring is rotated. Especially the full-open easy-open cover, the opening process is to lift the tab, use the rivet as the fulcrum, make the olecranon tip of the tab pierce the groove, turn over the tab to open the opening to a certain width, and then pull the tab back It can be fully opened along the groove....
