The present invention has been invented as described above, and the object of the present invention is to provide a container cover made of a synthetic resin which does not have a conformal property, and can be kept as a drinking port. Or, the owner ^ cry #, the opening of the main entrance without the pull ring from the easy to drink container cover. SUMMARY OF THE INVENTION In order to solve the above problems, the inventors of the present invention have made intensive research, and have found that an extension portion of a certain length can be formed in the occlusion portion, and is extended here: π The formation of the predetermined portion is provided with the locking portion. The configuration of the extension portion allows the t portion to be locked further, whereby the container lid made of a synthetic resin having no shape retaining property can be largely maintained as a drinking. Or the mouth of the mouth; the second part of the container cover such as the pull ring is not detached from the container cover, thus: cost invention. The cover of the present invention relates to the container cover of the following items: (1) - a type of container: it is specially held in the material system, the part around the occlusion portion is held in a table-like evil, and the other parts are broken to form a drinking. The container cap made of a synthetic resin made of the mouth or the mouth of the mouth includes: a pull ring provided in the closing portion, a peripheral edge breaking predetermined portion and a second inversion predetermined portion provided around the closing portion, and the blocking portion The rear side is extended to cooperate with the front portion - and after the occlusion portion: = two long portions: central rupture pre = the locking portion for maintaining the opening state of the occluding portion = ^ The part is provided on the back side of the closing portion, and () is in the container lid contained in (1) or (7), and the locking portion is a protrusion. </ br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br> In the container lid, the central fracture is fixedly disposed at a predetermined portion of the outer edge fracture, and the outer edge may be broken with the outer edge to form a band-shaped extension of a specific length; and (6) the container contained in (1) to 壬In the cover, the extension portion is formed at a predetermined portion.] 05080.doc 1304040 The pull ring is detached from the cover and is very easy to drink. The month of the occlusion portion is as long as it can be broken by the surrounding area.闭 卞 ^ The occlusion of the opening of the opening is not particularly limited. The plane of the cow from the center of the cover to the front side of the eye (the side of the drinking mouth) (seeing the front of the eyes, below) is seen one by one - The side of the occlusion mouth and the sputum of the octagonal shape, the teardrop shape, etc., as long as it belongs to the rear part of the occlusion part (h = side of the drinking opening) is preferably provided at the rear end portion, and the occlusion portion can be banded by hand Component: It can be 'not particularly limited', for example, a ring member or a sigh of the periphery of the occlusion portion The predetermined part means that the above-mentioned pull ring is pulled up and the heart is broken. Even if the pull ring is pulled up, the body of the cover body is connected to the top, and the part of the container is not linear or curved. The limit is provided with the outer edge reversing predetermined portion, and the closed base W (pull core) is not separated from the body of the crying squat. The other edge is to be cut by the predetermined portion by the right side of the occlusion portion. As a result, the stopper is locked to the upper right side, so the Yantas 4 + Γ 此外 此外 此外 预定 预定 预定 预定 预定 预定 预定 、 、 、 、 、 、 、 、 、 崎 崎 崎 崎 崎 崎 崎 崎 崎 崎 崎Knife / ... with "). Further, as the outer edge inverting predetermined portion, for example, a slit (thin portion) provided on the back surface of the container lid is exemplified. 2: The fixed part and the outer edge reversing plan are for the same industry, and the shape of the temple such as the depth and width of the cut can be set by the appropriate 2, and the valley is formed differently. Further, the extension portion of the specific length is formed by the predetermined portion on the rear side of the closing portion. y ^ The outer edge of the rupture i is the central portion of the rupture, which is the inside of the plug portion of J05080.doc Ι3Ό4040::: Similarly, the predetermined portion of the outer edge fracture is a portion which is broken by pulling up the tab, and is linearly and curved, and is particularly limited. The second flat portion (four) is provided at a predetermined portion of the outer edge to form a strip-shaped extension. If the extension portion is formed, the occlusion portion can be held in the deep reverse state by the front side of the occlusion portion, and the opening can be largely maintained. As described above, the financial center is "provided in parallel with the outer edge of the pre-turning portion" to form an extension having a desired length. The rotation = the aforementioned locking portion 'as long as it belongs to the rear portion of the blocking portion In the above-mentioned:: the predetermined portion is formed to maintain the above-mentioned occlusion 2::: stop-and-limit, and for example, a protrusion shape is used, and the second is easy, so that the household is a V-shaped portion (a protruding-shaped locking portion) is formed by molding. "ideal. This protrusion can be provided in the occlusion portion, but it is ideal from the point where it is easy to lock, the safety surface, and the beauty :::::. Further, the pull ring may have the following: 1: card: (4) is also included in the scope of the present invention. The card cover corresponding to the card 2 may be provided in the shape of the container cover corresponding to the card, for example, the mouth may be arranged, or the hook member or the insertion of the member (the insertion of the member, etc.). The dog-like member or the hook The member is preferably combined with the locked portion and the portion to be locked in the forming portion of the extending portion, and the back portion of the member is the "projector flange of the mounting body". Shape 襄...谷易. The body is formed in the molding, so the special opening can be used in the normal container..., especially to form the locked portion. W5080.doc (S) The outer edge of the back side of 1304040 is broken. The portion other than the portion 4 is provided with a straight-shaped slit outer edge inverting predetermined portion 5, as shown in Fig. 2(A), and is provided on the right rear portion of the closing portion when viewed from the front side. The shape of the groove depth and the width of the rupture predetermined portion 4 and the rim-overturning portion 5 are different. Further, the rear portion of the dam portion 2 is formed in the band-shaped extension portion 8 and is formed inside the occlusion portion 2. On the back side, a central break is scheduled in parallel at the outer edge breaking predetermined portion 4. The portion 6 can be formed, for example, in cooperation with the outer edge breaking predetermined portion 4, for example, a strip-shaped extension portion 8 having a length of 3 to 5 cm and a width of 3 to 1 cm. Further, the end portion side of the front side of the blocking portion 2 is fixed. When the pull ring 3 is pulled up, the outer edge breaking predetermined portion 4 and the central breaking predetermined portion 6 can be broken and the closing portion 2 can be opened. The locking portion 7 is stopped, and the locking portion 7 is provided with a protruding locking portion 7, and the opening portion of the portion 2 can be borrowed. Further, as shown in Fig. 3, the container lid holder 1 can also be configured to be inserted into the straw.
