Abstract
A safety cover comprises an inner plug and an outer cover. The coupling portions of the inner plug and outer cover are alternatively arranged with stopper and ribs. The inner surfaces of the limiting stoppers coupling to the ribs are inclined. When the ribs of the inner plug are separated from the limiting stoppers of the outer cover, the inner plug dose not rotate with the rotation of the outer cover. When the user presses the outer cover slightly, so that the buckle ring of the outer cover is embedded into the annular flange of the inner plug, the stopper ribs of the outer cover exactly slide along the limiting stoppers of the inclined surface of the inner plug to buckle the limiting stoppers. Thereby, the stopper ribs of the outer cover resist against the limiting stoppers of the inner plug to rotate therewith.
Description
- The present invention related to safety covers, and particularly to a safety cover wherein the coupling portions of the inner plug and outer cover are alternatively arranged with stoppers and ribs. The inner surfaces of the limiting stoppers coupling to the ribs are inclined. When the ribs of the inner plug are separated from the limiting stoppers of the outer cover; the inner plug dose not rotate with the rotation of the outer cover; when the user presses the outer cover slightly, so that the buckle ring of the outer cover is embedded into the annular flange of the inner plug, the stopper ribs of the outer cover exactly slide along the limiting stoppers of the inclined surface of the inner plug to buckle the limiting stoppers; thereby, the stopper ribs of the outer cover resists against the limiting stoppers of the inner plug to rotate therewith.
- In the prior art, the outer cover and inner plug are formed with threaded surfaces. Before locking the threaded surfaces, a press space is left for preventing the inner plug from rotation as the outer cover rotates. Thereby, a safety cover is formed. However, the no buckle structure is formed. The coupling of the inner plug and outer cover must be achieved by slightly adjusting the outer cover.
- Accordingly the primary object of the present invention is to provide a safety cover which comprises an inner plug and an outer cover locked to a periphery of the inner plug. The inner plug has a plurality of ribs. A top surface of the inner plug has an annular groove. The annular groove is installed with a buckle portion. The outer cover has an annular flange buckled with a buckling ring of the inner plug. The outer cover has a configuration corresponding to the ribs of the inner plug. A plurality of limiting stoppers are arranged around a whole inner surface of the outer cover. Each of an inner surface of each limiting stopper coupled to a respective rib of the inner plug is an inclined surface. A portion of the outer cover corresponding to the buckle portion of the inner plug is installed with a protruding annular ring for confining the buckled portion. When the ribs of the inner plug are separated from the limiting stoppers of the outer cover; the inner plug dose not rotate with the rotation of the outer cover; when the user presses the outer cover slightly, so that the buckle ring of the outer cover is embedded into the annular flange of the inner plug, the stopper ribs of the outer cover exactly slides along the limiting stoppers of the inclined surface of the inner plug to buckle the limiting stoppers; thereby, the stopper ribs of the outer cover resists against the limiting stoppers of the inner plug to rotate therewith.
- The various objects and advantages of the present invention will be more readily understood from the following detailed description when read in conjunction with the appended drawing.
- FIG. 1 is an exploded perspective view of the present invention.
- FIG. 2 is an assembled cross section view of the present invention.
- FIG. 3 is a plane cross section view showing that in the present invention, where the inner plug and outer cover are separated.
- FIG. 4 is a plane cross section view showing that the inner plug is buckled to the outer cover.
- FIG. 5 is a plane cross section view showing the separation state in another embodiment of the present invention.
- FIG. 6 is a plane cross section view showing the buckling state in another embodiment of the present invention.
- With reference to FIG. 1, the structure of the present invention is clearly shown. The present invention mainly includes an
inner plug 1 and anouter cover 2 locked to a periphery of theinner plug 1. - An inner surface of the
inner plug 1 is formed with a threadedsurface 11 which can be exactly locked to an opening of a can. An annular surface of theinner plug 1 is protruded with abuckling ring 12 which is engagable with theouter cover 2. A portion of theinner plug 1 resisting against theouter cover 2 has a plurality ofribs 13 which are arranged around a circle. A top surface of theinner plug 1 has anannular groove 14. A center of theannular groove 14 is installed with abuckle portion 15 which can be inserted into an inner top groove of theouter cover 2. - The
outer cover 2 has anannular flange 21 buckled with thebuckling ring 12 of theinner plug 1. A portion at a top inner surface of theouter cover 2 has a configuration corresponding to theribs 13 of theinner plug 1. A plurality of limitingstoppers 22 are arranged around the whole inner surface of theouter cover 2. The inner surfaces of thelimiting stoppers 22 coupled to theribs 13 of theinner plug 1 areinclined surfaces 221. The portion of theouter cover 2 corresponding to thebuckle portion 15 of theinner plug 1 is installed with a protrudingannular ring 23 for confining the buckledportion 15. - The assembly of the present invention is illustrated in FIG. 4. The
limiting stoppers 23 are the top inner surface of theouter cover 2 and theinner plug 1 is engaged to theannular ring 23 of theouter cover 2. Thebuckling portion 15 of theinner plug 1 exactly resists against theannular ring 23 of theouter cover 2. - Thereby, in general, the
buckling portion 15 of theinner plug 1 is exactly buckled to theannular ring 23 of theouter cover 2. Theribs 13 of theinner plug 1 are separated from thelimiting stoppers 22 of theouter cover 2 so that theinner plug 1 can not rotate with the rotation of the outer cover 2 (referring to FIG. 3). - When it is desired to rotate the
outer cover 2 to be out of theinner plug 1, the user only needs to press theouter cover 2 downwards so that thebuckle portion 15 of theinner plug 1 is exactly embedded into theannular ring 23 of theouter cover 2. Further, theribs 13 of theinner plug 1 slide downwards along thelimiting stoppers 22 of theinclined surface 221 of theouter cover 2 to be buckled to thelimiting stopper 22. Thereby, thelimiting stopper 22 of theouter cover 2 resists against therib 13 of theinner plug 1 to drive theinner plug 1 to rotate at the same time (referring to FIG. 4). After theouter cover 2 is tightened, the user applies a slight force to lift theouter cover 2 so that thelimiting stopper 22 of theouter cover 2 separates from therib 13 of theinner plug 1. Thereby, a safety cover is formed. - With reference to FIG. 6, another embodiment of the present invention is illustrated. A top inner surface of the
outer cover 2 is aligned to thelimiting stopper 22 of theinner plug 1 has anannular stopping rib 24. An inner surface of theouter cover 2 has anannular groove 25. A center of theannular groove 25 is concave so as to form abuckle ring 26. - The
inner plug 1 has an annularlimiting stoppers 16 which are arranged along a circle. An inner surface of eachlimiting stopper 16 is formed as aninclined surface 161. Thebuckle ring 26 of theinner plug 1 coupled to theouter cover 2 is installed with anannular flange 17 for receiving thebuckle ring 26. - Thereby, generally, the
buckling ring 26 of theouter cover 2 is exactly buckled to theannular flange 17 of theinner plug 1 so that when the stoppingrib 24 of theouter cover 2 is separated from thelimiting stoppers 16 of theinner plug 1, theinner plug 1 can not rotate with the rotation of the outer cover 2 (referring to FIG. 5). - When the user presses the
outer cover 2 slightly, so that thebuckle ring 26 of theouter cover 2 is embedded into theannular flange 17 of theinner plug 1, thestopper ribs 24 of theouter cover 2 exactly slide along thelimiting stoppers 16 of theinclined surface 161 of theinner plug 1 to buckle thelimiting stoppers 16. Thereby, the stopper ribs 24 of theouter cover 2 resist against thelimiting stoppers 16 of theinner plug 1 to rotate therewith (referring to FIG. 6). - Although the present invention has been described with reference to the preferred embodiments, it will be understood that the invention is not limited to the details described thereof. Various substitutions and modifications have been suggested in the foregoing description, and others will occur to those of ordinary skill in the art. Therefore, all such substitutions and modifications are intended to be embraced within the scope of the invention as defined in the appended claims.
