A CAN OPENER CONSTRUCTION WITH BETTER EASINESS IN OPENING AND ENHANCED SANITARINESS}

The present invention relates to a can lid structure with improved practicality, and more particularly to a can lid structure with improved open functionality and hygiene.

In more detail, the present invention relates to a can lid structure having a one-touch can opening means called EASY OPEN CAN having a so-called STAY ON TAB that can be easily opened. In particular, the operation of separating the opener end portions from the upper surface of the can body at appropriate intervals is performed by the pressing operation, and the operation of lifting the spaced opener end portions to open the inlet portion is separated and pressed to a predetermined portion of the opener to be sequentially performed. It is equipped with a weak part consisting of a pressing part, a curved bullet protrusion part, and a groove for performing the operation, which makes it possible to open the end of the opener at the same time, and to open it with a small amount. Cans for increased reliability, convenience and hygiene It relates to skim structure.

In general, various can lids having an opener 30 are used to easily open the inlet portion 22 of the can body 10, and the shape of the opening piece (開口 片) to form an opening portion. Pull open type to open and remove completely from the top of the can and open it, leaving the connecting part with the top of the can without removing the opening from the top of the can, or pushing the opening into the container. There are various types of can lid opening methods such as PUSH OPEN TYPE.

In addition, the type of opening that usually pulls the opener 30 and the opening piece is widely used in combination with the push-open type, which is pushed down into the container by the tip of the opener 30, which is generally made of steel or aluminum. In order to drink the contents, the inlet partitioned from the upper surface 20 by the dividing line 21 by lifting the opener 30 coupled to the upper surface 20 of the can by the rivet 24 to the top. By pushing the portion 22, the inlet portion 22 is divided with the upper surface 2 along the dividing line 21 to be opened so that the beverage contained in the can is drinkable.

However, such a conventional can is composed of a pressure-resistant can and a pressure-canned can, and is divided by the dividing line 21 by a water hammer phenomenon (a liquid splashing out of the can due to an external impact and pushing the can lid). Shear stress is applied to the inlet part 22 and the split line 21 breaks, so that the inlet part 22 is opened due to a phenomenon in which the split line 21 is partitioned to a predetermined thickness or more to withstand the shear stress. Breaking the dividing line 21 requires a certain amount of force and this force must depend entirely on the force applied to the opener 30, which is from the point of lifting the distal end 31 of the opener 30. Since one side of the opener 30 is in close contact with the inlet portion 22 partitioned by the 21, a considerable force is required for the lifting operation, so that a child or an elderly person frequently asks for help from another person and opens it. Ha In addition, it is also inconvenient to open the inlet part 22 again by picking up the opener end part 31 by lifting the opener end part 31 and then inserting a finger between the lifted part and the upper surface of the can. This occurred, and also the opener end portion 31 is placed in close contact with the upper surface of the can 20, so there is no room for the finger to lift the opener end portion 31 using nails, etc. At this time, the nail part feels pain. Many problems occurred, including severe injury. In addition, the can inlet 22 is exposed to various pollutants in the can distribution, there is also an unsanitary problem.

Therefore, the present invention has been made to fundamentally solve the above problems of the prior art, the object of which is to make the operation of separating the opener distal end from the upper surface of the can body by the pressing action, the distal end is spaced from the upper surface of the can Lifting the opener to open the inlet portion is formed by forming a weak portion consisting of a groove in a certain portion of the opener to be separated and sequentially made, or a pressing portion or a curved bullet projection and groove to perform a pressing operation on a certain portion of the opener By providing a groove portion made of, it is easy to open the end of the opener and at the same time can be opened with a small force, and to provide a one-touch can lid structure to improve the hygiene problems.
