The combination is more secure. In addition, the outer wall surface of the plug body 2 can also be provided with a plurality of fins 23, so that when the plug body 2 is closed at the opening of the container, the plug body 2 and the container can be made by the appropriate friction force provided by the number of flaps 23. A better sealing effect between the openings.

The enlarged diameter body 3 has a post 31 which can be bored through the through hole 12 of the body 1 and fixed at a predetermined position. The fixing can be various conventional fixing methods such as an adhesive. In the embodiment, the pole 31 is provided with a second joint portion 32. The second joint portion 32 can be combined with the first joint portion 15 of the body 1 so that the diameter-expanding body 3 can be fixed by the pillar 31. At a predetermined position of the through hole 12 of the body 1, the second joint portion 32 may be a protruding number of ring one-way ratchets, so that the first joint portion 15 forming the one-way ratchet can be engaged with the second joint portion 32. In order to prevent the expansion body 3 from moving in the reverse axial direction. The enlarged diameter body 3 further includes a tapered portion 33 adjacent to the post 31, and the tapered portion 33 is expanded in diameter from the adjacent portion of the post 31 toward the end portion. The tapered portion 33 can abut against the inner wall of the expansion piece 14 of the body 1, and the expansion piece 14 can be radially expanded by the tapered portion 33. That is, the post 31 of the enlarged diameter body 3 is fixed at a relative position of the through hole 12 of the body 1, so that the expanded piece 14 of the body 1 can be radially expanded to a predetermined size.

Referring to FIG. 3, when the operator wants to make the external expansion container plug better, it is also possible to use a cover 4 to be coupled to the container stopper formed by the body 1 and the plug body 2. The cover 4 may be made of the same material as the container of glass, ceramics, porcelain, or the like. The cover body 4 has a top surface and a bottom surface. The cover body 4 is provided with an inner hole 41. The hole edge of the inner hole 41 has an edge convex portion 42. The edge convex portion 42 has a smaller diameter than the inner hole 41. straight path. The bottom surface of the cover body 4 may further be provided with a counterbore portion 43 from which the fixing plate 11 of the body 1 can be accommodated, so that the container plug can form a better appearance.

Referring to FIG. 4 , when the container plug of the present invention is not combined with the cover body 4 , the plug body 2 is coupled to the outer wall of the body 1 , and the expanded diameter body 3 is disposed through the through hole 12 of the body 1 . To form a container plug together, at this time, the lid 4 has not been combined with the container stopper.

Referring to FIG. 5, the container plug formed by the main body 1, the plug body 2 and the enlarged diameter body 3 can also be combined with a cover body 4, which is a tapered portion 33 and a body 1 of the expanded diameter body 3. The expansion piece 14 is disposed in the inner hole 41 of the cover body 4, and the top of the tapered portion 33 of the enlarged diameter body 3 abuts against the bottom of the inner hole 41 of the cover body 4 (in the drawing), and is externally driven. The rod 31 of the enlarged diameter body 3 is moved axially downward relative to the through hole 12 by a predetermined distance (in terms of the drawing). Therefore, the tapered portion 33 can force the expansion piece 14 of the body 1 to be located at the edge convex portion. The inner hole 41 of the rear side of the portion 42 is radially expanded. Thus, the expanded piece 14 has a radial dimension larger than that of the edge convex portion 42 and is blocked on the rear side of the edge convex portion 42. The pole 31 of the enlarged diameter body 3 can be fixed to a relative position of the body 1. In this embodiment, since the pole 31 of the enlarged diameter body 3 is provided with the second joint portion 32, the second joint portion 32 can be combined with the first joint portion 15 of the body 1 to expand the joint. The pole 31 of the radial body 3 is fixed to a predetermined position of the body 1 and the cover body 4 is brought into engagement with the body 1. Thus, the combination of the lid body 4 and the container plug (that is, the combination of the body 1, the plug body 2, and the diameter-expanding body 3) can be facilitated, and the lid body 4 and the container plug are not peeled off.

Please refer to Figures 6 and 7, which are the expanded body 3 and the body 1 of the present invention. In another preferred embodiment of bonding and fixing, the enlarged diameter body 3 and the body 1 are fixed in a screwing manner. In the embodiment, the aperture of the through hole 12 of the body 1 forms a single inner diameter, and the pole 31 of the enlarged diameter body 3 is provided with a threaded second joint portion 32, and the second joint portion of the threaded portion is formed. The 32 series can be used to screw a screw member 34. The diameter-expanding body 3 is preferably non-rotatable with respect to the body 1. For example, the cross-section of the tapered portion 33 of the enlarged diameter body 3 and the inner wall surface of the number of the expansion sheets 14 of the body 1 can form the same non-positive The circular shape, or as shown, the tapered portion 33 of the enlarged diameter body 3 is provided with a radially projecting projection 35 which can be embedded in the gap 17 between the adjacent ones of the plurality of expanded sheets 14. Therefore, when the screwing member 34 is screwed to the second joint portion 32 of the enlarged diameter body 3, the expanded diameter body 3 can be formed so that the screwing member 34 can be easily rotated without being rotated.

Please refer to FIG. 7 , which is a case where the body 1 and the cover 4 of the present invention are not combined. At this time, the plug body 2 and the body 1 are also separated and uncoupled, and the expanded body 3 is worn. In the through hole 12 of the body 1, and the second joint portion 32 of the enlarged diameter body 3 is coupled with the screwing member 34, the body 1 and the expanded diameter body 3 are combined.

Referring to FIG. 8, when the container plug needs to be coupled to a cover body 4, the combined body 1 and the enlarged diameter body 3 can be used for the expansion piece 14 of the body 1 and the tapered portion of the expanded diameter body 3. 33 is inserted through the inner hole 41 of the cover body 4, and by the rotation of the screwing member 34, the enlarged diameter body 3 is longitudinally moved to the through hole 12 of the body 1, and the expanded diameter body 3 The tapered portion 33 can press the expansion piece 14 to form the expansion piece 14 to be radially expanded. Thus, the expansion piece 14 can be expanded to have a larger radial dimension than the edge protrusion 42 and is blocked at the edge protrusion 42. Back side. In the present embodiment, due to the pole of the enlarged diameter body 3 The second joint portion 32 is provided with the second joint portion 32, and the second joint portion 32 is screwed with the screw member 34. Therefore, the rod 31 of the diameter-expanding body 3 can be fixed to a relative position of the body 1 so that The cover 4 and the body 1 are combined for the purpose.

Referring to FIG. 9, when the cover body 4 is combined with the body 1, the plug body 2 can be combined with the body 1. Thus, the container plug can be formed with a cover 4 of the same material as the container. Moreover, the cover 4 does not fall off the container.

The invention further comprises an expanded container plug, which can be combined with a cover body of the same material as the container, so that the container plug has the effect of better appearance effect.

According to the present invention, the expanded container plug can be combined with the existing container lid, so that the effect of re-making the mold for the mold for the lid can be avoided.

While the invention has been described in connection with the preferred embodiments described above, it is not intended to limit the scope of the invention. The technical scope of the invention is protected, and therefore the scope of the invention is defined by the scope of the appended claims.
