Description

Technical Field

[0001] The utility model relates to the technical field of cans, in particular to a beer or beverage can. Background Art

[0002] The can is a common beer (beverage) packaging container, which has the characteristics of being portable, having good sealing performance, and being easy to open, etc. The existing cans include a breaking piece lever structure and a pull ring structure.

[0003] The breaking piece lever structure is a breaking piece riveted on the top of the can lid. The riveting position of the breaking piece is in the middle of the lid. There is a tear line engraved on the can lid. The tear line is located on one side of the breaking piece. When in use, the breaking piece is lifted up on the side away from the tear line by the lever principle, and the other side of the breaking piece presses the tear line area into the can to form the can mouth. The breaking piece structure uses the riveting point as the fulcrum, and the power arm formed is equal to the resistance arm in length or slightly larger than the resistance arm. Therefore, the breaking force required to open the can mouth is large, which is not labor-saving. For people with less strength, they may need to use other tools to open the can, which is inconvenient.

[0004] The pull-ring structure is a closed tear line engraved on the top of the can lid, and a pull-ring is riveted on one side of the tear line. The riveting point between the pull-ring and the tear line is located in the center of the lid. When opening the can, the pull-ring needs to be pulled up rigidly. At this time, the tear line starts to break from the center of the lid, and then extends outward to the edge of the lid until the tear area is completely torn off to form the can mouth. The pull-ring structure does not use a labor-saving structure when opening the can mouth. It needs to be opened by hard pulling, which is laborious and inconvenient to use. In addition, after opening the can, the pull-ring is separated from the can body, making it inconvenient to recycle the whole. Utility Model Content

[0005] In order to overcome the deficiencies of the prior art, the utility model aims to provide a beer or beverage can to solve the problem that it is laborious to open the existing cans.

[0006] The technical solution adopted by the utility model is as follows:

[0007] A beer or beverage can comprises a can body and a cover body which is rolled and fixed to the opening of the can body, the top surface of the cover body is provided with a tearing area for forming the can mouth, the edge of the tearing area is provided with an unclosed tear line, a pull ring is connected to the tearing area on the side away from the end point of the tear line, the edge of the pull ring close to the connection position with the tearing area is provided with a supporting part which can be abutted against the top surface of the cover body, and a force applying part is provided on the side of the pull ring away from the supporting part, and by bending the force applying part upwards, the pull ring opens the tearing area with the supporting part as a fulcrum.

[0008] Compared with the prior art, the principles and beneficial effects of the utility model are as follows:

[0009] This scheme adopts the lever principle, with the pull ring as a lever, the support part as a fulcrum, the force-applying part as a power point, and the connection position between the pull ring and the tearing area as a resistance point. When opening the can, by bending and pulling up the force-applying part, the pull ring uses the support part as a fulcrum to bend and pull up the tearing area. At this time, a small opening is torn in the tear line closest to the resistance point, and then the pull ring is pulled upward, and the tearing area continues to tear from the opening to the outside along the tear line until it reaches the end point of the tear line of the cover body, and the tearing area is torn to form the can mouth. In this process, since the resistance point is close to the fulcrum, the distance between the resistance point and the fulcrum is the resistance arm, and the power point is far away from the fulcrum, and the distance between the power point and the fulcrum is the power arm. According to the lever balance condition: the magnitude of the power and resistance is inversely proportional to the length of the corresponding force arm, therefore, only a small initial force needs to be applied to tear the tear line through the pull ring, which is more labor-saving. In addition, since the two end points of the tear line are not closed, after the tear area is torn to form the can mouth, the pull ring is bent to the edge of the cover body on the opposite side of the can mouth and placed, which is convenient for drinking without obstruction. The end point of the tear line is connected to the cover body, and after the beer (beverage) is consumed, the can body, the cover body and the pull ring can be recycled as a whole.

[0010] As a preferred embodiment of the utility model, the edge of the top surface of the cover body is provided with an annular plate, and the inner and outer circular edges of the annular plate are provided with two annular reinforcing ribs, and the support part is placed against the upper surface of the annular plate. The annular plate provided in this solution can play the role of reinforcing ribs. Since the fulcrum position is subjected to greater force when the lever is working, this solution can increase the strength of the position where the top surface of the cover body and the support part are in contact by providing an annular plate, and the annular reinforcing ribs provided at the same time can help increase the resistance of the tear line when it is torn.

[0011] As a preferred embodiment of the utility model, the top surface of the cover body is provided with a clearance groove corresponding to the force applying part. The clearance groove provided in this solution can facilitate placing fingers in the clearance groove when opening the can, so that the fingers can be smoothly buckled on the force applying part, which is convenient for force application.

[0012] As a preferred embodiment of the utility model, a clearance step is provided on the lower side of the force applying part. The clearance step provided in this solution can increase the gap between the force applying part and the clearance groove, further increase the clearance space, and help the fingers buckle on the force applying part for applying force.

[0013] As a preferred embodiment of the utility model, a connecting portion extends inwardly from the inner side of the pull ring, a rivet hole is opened on the connecting portion, a rivet is provided in the tearing area to match the rivet hole, and the connecting portion is riveted to the tearing area.

[0014] As a preferred embodiment of the utility model, the distance from the force-applying part to the support part is equal to five times the distance from the rivet to the support part. According to the balance condition of the lever: the magnitude of the power and the resistance is inversely proportional to the length of the corresponding force arm. In this solution, the distance from the force-applying part to the support part is the power arm, and the distance from the rivet to the support part is the resistance arm. Since the power arm is equal to five times the resistance arm, in order to meet the balance condition of the lever, when opening the bottle cap, only one-fifth of the resistance needs to be applied to the force-applying part, that is, five times the initial force can be saved.

[0021] Typical embodiments that embody the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention can have various changes in different embodiments without departing from the scope of the present invention, and the descriptions and illustrations therein are essentially for illustrative purposes rather than for limiting the present invention.

[0022] In the description of the present application, the terms "top", "bottom", "one end", "one side", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the structure referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they should not be understood as limitations on the present application.

[0023] See also Figure 1-3As shown, this embodiment discloses a beer or beverage can, including a can body 1 and a cover body 3, wherein the can body 1, the cover body 3, and the pull ring 2 are all sheet metal structures. The edge of the cover body 3 is provided with a frill 33, which is roll-formed on the edge of the can mouth of the can body 1. The top surface of the cover body 3 is provided with a tearing area for forming the can mouth, and the edge of the tearing area is engraved with a tear line 31, which includes an arc segment close to the edge of the top surface of the cover body 3, and two straight line segments extending from the two ends of the arc segment, and the free ends of the two straight line segments are both located in the middle of the top surface of the cover body 3. A pull ring 2 is connected to the tearing area near the edge of the top surface of the cover body 3, and the pull ring 2 is used to tear open the tearing area. Specifically, the pull ring 2 includes a triangular portion located on the front side and a circular ring portion located on the rear side. The circular ring portion and the triangular portion are integrally formed, and the circular ring portion is aligned with the center of the top surface of the cover body 3. The tip of the triangular portion extends inward to form a connecting portion 21. A rivet hole 22 is opened on the connecting portion 21. The tearing area is integrally stamped with a rivet 311 to cooperate with the rivet hole 22, and the connecting portion 21 is riveted to the tearing area.

[0024] The edge of the tip of the triangle portion can be placed against the top surface of the cover body 3, the edge of the tip of the triangle portion is set as the support portion 25, and the side of the annular portion away from the support portion 25 is set as the force-applying portion 23. When in use, by pulling up the force-applying portion 23, the pull ring 2 pulls up the rivet 311 with the support portion 25 as a fulcrum, and the force applied to the rivet 311 acts on the tear line 31. At this time, a small opening is torn in the tear line 31 closest to the rivet 311, and then the pull ring 2 is continuously pulled upward, and the tear line 31 continues to tear outward from the opening until it reaches the end point of the tear line 31, and the tear area is torn to form a can mouth. The pull ring 2 in this solution uses the lever principle to tear the tear area, which is more labor-saving.

[0025] Furthermore, the top surface of the cover body 3 is integrally formed with an annular plate 4, and the inner and outer circular edges of the annular plate 4 are integrally formed with two annular reinforcing ribs 41, and the support portion 25 is placed against the upper surface of the annular plate 4 and is located between the two annular reinforcing ribs 41. Since the fulcrum position is subjected to greater force when the lever acts, the strength of the fulcrum position can be increased by providing the annular plate 4.

[0026] Furthermore, a clearance groove 32 is provided on the top surface of the cover body 3 corresponding to the force applying part 23, and a clearance step 24 is provided on the lower side of the force applying part 23. By providing the clearance groove 32 and the clearance step 24, the clearance space can be increased when opening the can, so that the fingers can be smoothly buckled on the force applying part 23, which is convenient for force application.

[0027] Furthermore, the distance between the force-applying part 23 and the support part 25 is equal to five times the distance between the rivet 311 and the support part 25. According to the balance condition of the lever: the magnitude of the power and the resistance is inversely proportional to the length of the corresponding force arm. Since the distance between the force-applying part 23 and the support part 25 is the power arm, and the distance between the rivet 311 and the support part 25 is the resistance arm, the power arm is equal to five times the resistance arm. To meet the balance condition of the lever, when opening the can, only one-fifth of the force needs to be applied to the force-applying part 23, which is more labor-saving.

[0028] Specific implementation process:

[0029] When opening the can, place your finger on the air-avoiding groove 32 and pull up the force-applying part 23. At this time, a small opening is torn in the tear line 31 near the rivet 311. Then continue to pull the pull ring 2 upward, and the tear line 31 continues to tear from the opening outward until it reaches the end point of the tear line 31. The torn area is torn to form the can mouth. After the can mouth is completely torn, fold the torn area along the line connecting the two end points of the tear line 31 to the top surface of the cover body 3, then flatten the pull ring 2 and place it on the top surface of the cover body 3, or bend the pull ring 2 to a certain angle so that the pull ring 2 is against the side wall of the can body 1, and then you can start drinking.

[0030] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
