The can plate 200 is formed with a guide hole 204 extending from the entrance hole 202. At this time, the guide hole 204 is preferably disposed at a right angle to the access hole 202. The can plate 200 is formed with a circular fixed protrusion 206. The can plate 200 is preferably formed of aluminum, steel, or the like, but is not limited thereto. In addition, the can plate 200 may be made of a plastic material such as a polymer.

The upper opening plate 210 and the lower opening plate 220 is preferably formed of a plastic material, but is not limited thereto. The fitting hole 212 is formed at an approximately central position in the upper opening plate 210. The can top plate 200 is formed with a fixed protrusion 206 having a concave shape in a circular shape. The connection guide shaft 222 protrudes upward on the surface of the lower opening plate 220 so as to be fitted to the fitting hole 212 through the guide hole 204. The lower opening plate 220 is formed with recesses 228 having a concave shape in a circular shape so that the fixing protrusions 206 are inserted therebetween. The connecting guide shaft 222 slides along the guide hole 204 together with the upper opening plate 210. The connection guide shaft 222 is provided with a gas discharge hole 224 to which the sealing plug 232 is fitted.

The sealing member is preferably formed of a sealing tape 230 made of vinyl, which is commonly used, but other similar materials may be used. The sealing plug 232 protrudes downward from the bottom surface of the sealing tape 230. The handle 234 extends to one side of the sealing tape 230 to protrude. The sealing tape 230 is disposed at a right angle with respect to the guide hole 204 of the can plate 200. This is to prevent interference with the movement of the upper opening plate 210 and the lower opening plate 220 sliding along the guide hole 204. In particular, as indicated by the dotted lines in FIG. 2, the sealing tape 230 has a cutout line 236 formed along its outer circumference. That is, when the sealing tape 230 is attached to the can plate 200, it does not fall into a complete bond to the outside centered around the dotted line, and inside the user relatively easily by the force to pull the sealing tape 230 Let it fall In addition, it is preferable that a part of the sealing tape 230 is completely attached to the can plate 200 so that the sealing tape 230 is not completely separated from the can plate 200.

The sealing filler 240 to be described later is provided between the fixed protrusion 206 and the fixed groove 228. In addition, the filler 240 is provided between the upper opening plate 210 and the connecting guide shaft 222. The filler 240 is preferably an elastomer such as natural rubber and synthetic rubber, but is not limited thereto.

With reference to the accompanying drawings will be described the operation of the retractable sliding can end according to a preferred embodiment of the present invention having the structure as described above.

3 is a cross-sectional view taken along line A-A of FIG. 2 showing a sealed state. 4 is a cross-sectional view taken along the line A-A of FIG. 2 with the tape partially removed. 5 is a cross-sectional view taken along the line A-A of FIG. 2 in a state where the entrance hole of the can plate is partially opened. FIG. 6 is a cross-sectional view taken along line B-B of FIG. 2.

Referring to FIG. 3, the can end is in a state in which the entrance hole 202 is closed by the upper opening plate 210 and the lower opening plate 220. In addition, the upper opening plate 210 is covered with the sealing tape 230. In this state, the internal pressure of the canister (not shown) is maintained. That is, the sealing plug 232 provided in the sealing tape 230 is a state in which the gas discharge hole 224 of the connecting guide shaft 222 is sealed.

In this case, the filler 240 is positioned between the fixing protrusion 206 of the can plate 200 and the fixing groove 228 of the lower opening plate 220. For this reason, the gap between the fixed protrusion 206 and the fixed groove 228 is more tightly contacted by the filler 240. In addition, the lower opening plate 220 is brought closer to the bottom surface of the filler 240 and the can plate 200 by the internal pressure of the can container (not shown), thereby greatly improving the sealing force. The sealing tape 230 serves as an auxiliary for preventing internal gas leakage through the circumference of the opening plate.

Then, as shown in FIG. 4, when the user of the can container grasps the handle 234 of the sealing tape 230 and pulls it in one direction to drink the beverage, the sealing tape 230 is attached to the can plate 200. Slowly fall off the site. At this time, only the inner part of the sealing tape 230 is separated from the can plate 200 with the cutting display line 236 as a boundary. This is because the sealing tape 230 is strongly attached to the outside of the cut-out line 236 so that the inside of the sealing tape 230 can be detached relatively easily. By doing so, the user can know whether the canned plate 200 is opened by looking at the cutout display line 236 left on the upper surface of the canned plate 200.

In this process, when the sealing tape 230 is gradually dropped from the can plate 200, the sealing stopper 232 of the sealing tape 230 is removed from the gas discharge hole 224 of the connecting guide shaft 222. Thus, the gas inside the can vessel (not shown) is partially discharged to the outside. For this reason, the internal pressure of the can container (not shown) which pushed itself lowers the lower opening plate 220 disappears. As a result, the lower opening plate 220 is released while being in close contact with the can plate 200, whereby the upper opening plate 210 and the lower opening plate 220 can be easily slid in the can plate 200. .

Subsequently, as shown in FIG. 5, the user pushes the upper opening plate 210 of the can plate 200 in one direction while being slightly pressed downward. Then, since the upper opening plate 210 and the lower opening plate 220 are in a coupled state with each other, the upper opening plate 210 and the lower opening plate 220 are slidably moved along the guide hole 204 of the can plate 200. Here, the fixing groove 228 of the lower opening plate 220 is separated from the fixing protrusion 206 of the can plate 200. Accordingly, the entrance and exit hole 202 of the can plate 200 is opened to be in a state capable of drinking. At this time, since the sealing tape 230 is disposed at a right angle with respect to the guide hole 204, the sealing tape 230 does not interfere with the movement of the upper opening plate 210. The canned plate 200 prevents the fixed protrusion 206 and the fixed groove 228 of the lower opening plate 220 from being slid before a predetermined force is applied.

In addition, after the user has consumed the contents in the canister (not shown), storage is possible. That is, the user slides the upper opening plate 210 and the lower opening plate 220 to their original state to seal the entrance hole 202 of the can plate 200. At this time, the fixing protrusions 206 of the can plate 200 are positioned in the fixing grooves 228 of the lower opening plate 220, respectively, to be fixed without moving (see FIG. 6).

As mentioned above, according to the openable sliding can end according to the embodiment of the present invention, by removing the existing opening tab, the upper plate and the lower opening plate is coupled to the can plate to be slidably moveable, Since the access hole is formed and only the coupling operation of the upper opening plate and the lower opening plate is performed, there is an effect of reducing the work process and improving productivity. In addition, it is possible to greatly reduce the material cost by replacing the can plate made of only aluminum with steel or plastic.

In addition, the can top plate is made of steel or aluminum, and the upper opening plate and the lower opening plate are made of plastic, so that when the can end is manufactured and packaged in pieces, the bottom of the can end, that is, the top of the bottom opening plate and the can end, In other words, the sealing tape is in contact so that there is no fear of the coating peeling off. In addition, recovery is advantageous because the upper opening plate and the lower opening plate do not easily fall from the can plate during recycling, and even if these parts are melted at once, the plastic melts first, so only carbon and hydrogen are generated, so that there is no problem on the environment.

On the other hand, when the sealing tape is removed from the can plate, only a part of the sealing tape falls off around the cutout line, so it is easy to know whether it is opened.

In addition, in the present invention, the upper opening plate and the lower opening plate can be slid to open and close the access hole of the can plate, so that it is convenient to drink during the movement or time, and there is no fear of infection by foreign substances such as insects even during storage. .

In the above, the present invention has been described in detail with reference to the above-described embodiments, but the present invention is not limited thereto, and those skilled in the art may change or improve the technology within the scope of ordinary knowledge.
