FIELD OF THE INVENTION
[0001] This invention relates to a safe inner plug for bubble blowing fluid bottle designed to prevent the bubble fluid from seeping off, in particular when the bent fluid stick is pulled out of the fluid bottle, there is always excessive bubble fluid on the fluid stick, and the plug will scrape the bubble fluid off the fluid stick, so no bubble fluid is wasted.
BACKGROUND OF THE INVENTION
[0002] There are many bubble blowing toys available on the market for sale and the manufacturers are taking an aggressive effort in developing a variety of novel and fancy bubble blowing toys in an attempt to induce the strong purchase desire from the consumers. However, in most cases, the bubble blowing toy provides a fluid stick which is always directly fastened to the twist cap, permitting the bubble fluid directly contact the cap. When the cap is opened, only a part of the excessive bubble fluid attached the fluid stick can be removed by sweeping the fluid stick on the bottle mouth, and most is dripped and wasted.
[0003] Due to such seepage and dripping of bubble fluid, the inventor has spent years in designing a stop at the bottle mouth to prevent the seepage of bubble fluid which possesses the industrial practicable value at the same time.
SUMMARY OF THE INVENTION
[0004] The primary object of the invention is provide a base plate which is cut into a plurality of slots to work as the scrapers which enable to remove the excessive bubble fluid attached to the fluid stick to avoid the incautious dripping or the waste of bubble fluid.
[0005] Another object of the invention is to provide a concave void which is employed in one way to keep the bubble fluid away from the bottle mouth and in other to collect and return the excessive bubble fluid to the bottle.
[0006] Another object of the invention is to provide a downward extended base plate on the safe inner plug. When the bottle is shaken or toppled down, the bubble fluid is allowed to flow and contact the base plate, but never reaches the twist cap so as to prevent seepage of bubble fluid coming out of the bottle mouth.
[0007] Another object of the invention is to provide a fluid stick which is in a bent or curved form. When pulling off, it goes through the scraper to make some fantastic music.
[0008] The invention is explained in great details with an aid of the preferred embodiment as illustrated in the drawings attached.

DETAILED DESCRIPTION OF THE INVENTION
[0019] As shown in FIGS. 1 and 10, the safe inner plug 1 is inserted in the bottle mouth 41 of the fluid bottle 4 and closely seals the bottle mouth 41. The safe inner plug 1 constitutes a brace ring 11, a base plate 12 and a concave void 13, wherein the base plate 12 and the concave void 13 are installed in the inner side of the brace ring 11. The base plate 12 has at least two radial cuts 121 to form a plurality of scrapers 122 which are a critical device to stop seepage of the bubble fluid from the fluid bottle 4. Since the bubble fluid is kept off the cap 3, the bubble fluid will never contaminate the bottle mouth 41 and the cap 3, so the bottle mouth 41 and the cap always remain in neat condition.
[0020] As shown in FIGS. 2 through 4, the safe inner plug 1 has a base plate 12 and a concave void 13 which is disposed on the top of the base plate 12. The scraped bubble fluid will stay in the concave void 13 temporarily and returns to the fluid bottle 4 finally. The base plate 12 has several modifications as described below.
[0021] As shown in FIG. 2, the base plate 12 of the safe inner plug 1 is an inward extension from the bottom of the circular wall 14 and is disposed lower than the brace ring 11, and a concave void 13 is formed between said base plate and the inner side of said circular wall 14. As shown in FIG. 3, the base plate 12 of the safe inner plug 1 extends inward from the joint of the brace ring 11 and the circular wall 14 and inclines downward in an angle to the center to form a tapered concave void 13 which leads the excessive bubble fluid into the fluid bottle 4. As shown in FIG. 4, the base plate 12 is in a curved form, so is the concave void 13. The concave void 13 of the safe inner plug 1 is used to collect and to store temporarily the excessive bubble fluid removed from the fluid stick in one end and keeps the bubble fluid from directly contacting the cap 3 in another end. This is a unique way to stop seepage of bubble fluid.
[0022] As shown in FIGS. 5 through 7, the radial cuts 121 of the base plate 12 of the safe inner plug 1 are in radial arrangement so as to convert the base plate 12 into a plurality of scrapers 122. The fluid stick 2 penetrates into the fluid bottle 4 through the scrapers 122 as illustrated in FIG. 10. The opening 123 in the center of the scrapers 122 of the base plate 12 can be made in a round or square pattern to suit the shape of the shank 21 of the fluid stick 2.
[0023] As shown in FIGS. 8 and 9, the top shank 21 end of the fluid stick 2 is linked to the cap 3 and the lower shank 21 end with the bubble forming ring 22. The shank 21 can be in a pattern of screw, wave, or straight rod. When the fluid stick 2 is pulled through the scrapers 122, the friction produces a fantastic music to give more fun for it. When the fluid stick 2 is pulled out, the excessive bubble fluid attached to the shank 21 will be entirely shaved off by the scrapers 122 of the base plate 12 of the safe inner plug 1, keeping the fluid stick 2 clean and neat.
[0024] As shown in FIG. 10, when the fluid stick 2 is pulled upward, the bent shank 21 of the fluid stick 2 will push the scrapers 122 of the base plate 12 upward, there the excessive fluid attached to the shank 21 is shaved off to prevent any dripping of bubble fluid on the ground.
