Description

Technical Field

[0001] The utility model relates to the field of containers, in particular to a perfume refill bottle with anti-wear bottom filling. Background Art

[0002] Perfume is a liquid that can make people feel pleasant by emitting fragrance. After consumers buy a whole bottle of perfume, in order to facilitate carrying, they need to refill the perfume into a smaller bottle. In order to reduce the volatilization and spilling of perfume during refilling, the bottom filling method is generally used for refilling. At present, the bottom filling structure of the perfume refill bottle with anti-wear bottom filling on the market is complex in structure and prone to leakage. For example, a cosmetic container with the publication number of CN102871336A is provided with a sealing ring on each of the upper and lower sides of the lower valve outlet, and an O-ring is also provided at the bottom below. The two sealing rings can ensure that when not refilling, the upper sealing ring prevents the perfume in the container body from flowing into the channel and flowing out from the outlet of the lower valve. When refilling, a gap is formed between the lower valve and the channel, resulting in leakage. The O-ring needs to be movably matched with the small ribs on the inner wall of the channel. When the lower valve rises for refilling, the O-ring moves upward and is squeezed by the small ribs, so that a gap is formed between the O-ring and the inner wall of the channel for exhausting air. When the lower valve descends and is not refilling, the O-ring moves downward and disengages from the small ribs and forms a seal with the channel, so that an air seal is formed in the return air pipe. This structure not only requires multiple sealing rings and O-rings to be provided on the lower valve, but also requires small ribs to be machined in the channel to cooperate with the O-ring. Moreover, the sealing ring above the outlet will rub against the end of the channel when moving up and down, and the sealing ring is easily damaged and the seal fails, resulting in leakage. When the O-ring repeatedly rubs against the small ribs, it is easily cut by the small ribs, resulting in seal failure and the inability to form an air seal in the return air pipe, and the perfume in the container body is easily leaked out from the return air pipe.

[0015] The technical solutions of the present utility model will be further described below in conjunction with the drawings and preferred embodiments.

[0016] Such as Figure 1 , Figure 2As shown in the figure, the perfume refill bottle with anti-wear bottom filling of the present utility model includes: a bottle body 1, which is made of transparent glass material. A liquid storage cavity 11 and a filling cavity 12 are provided in the bottle body 1. A partition plate 13 is provided between the liquid storage cavity 11 and the filling cavity 12. A valve seat 14 is hermetically arranged at the top of the liquid storage cavity 11. A pressing pump 15 is arranged in the valve seat 14. A bottle cap 16 is clamped on the valve seat 14. The bottle cap 16 covers the outside of the pressing pump 15 to protect the pressing pump 15. A connecting column 131 extends upward on the partition plate 13. An installation hole communicating the liquid storage cavity 11 and the filling cavity 12 is opened in the connecting column 131. An exhaust pipe 17 is inserted into the installation hole. The exhaust pipe 17 extends upward into the liquid storage cavity 11. The exhaust pipe 17 is in interference fit with the installation hole. A communicating hole 132 and a frustum-shaped hole 133 are provided in the partition plate 13 and are connected. An upper sealing gasket 2 is hermetically clamped in the frustum-shaped hole 133. A sealing boss 21 extends outward on the upper sealing gasket 2. The sealing boss 21 abuts against the partition plate 13. The aperture of the sealing hole of the upper sealing gasket 2 is smaller than the aperture of the communicating hole 132. A needle valve 3 is slidably sealed in the sealing hole of the upper sealing gasket 2. A feed channel 31 penetrating the bottom wall and the side wall is opened in the needle valve 3. A spring 32 is sleeved on the needle valve 3. The top of the spring 32 abuts against the sealing boss 21 of the upper sealing gasket 2. The top thrust of the spring 32 can ensure the sealing stability between the upper sealing boss 21 and the partition plate 13, thereby improving the sealing performance of the upper sealing gasket 2. A plug body 4 is hermetically arranged in the filling cavity 12. The plug body 4 does not extend downward out of the filling cavity 12. The plug body 4 is in interference fit with the filling cavity 12 to improve the sealing performance and connection stability between the plug body 4 and the filling cavity 12. A positioning ring 41 protrudes on the outer side wall of the plug body 4. A positioning groove 121 is recessed on the inner side wall of the filling cavity 12. The positioning ring 41 on the plug body 4 is snapped into the positioning groove 121 in the filling cavity 12. An avoidance hole 42 is opened on the bottom wall of the plug body 4. A lower sealing gasket 5 is movably arranged on the plug body 4. A first exhaust annular gap of 0.1 mm to 0.15 mm is left between the lower sealing gasket 5 and the inner side wall of the plug body 4. The needle valve 3 abuts against the lower sealing gasket 5. The outer diameter of the needle valve 3 is not greater than the outer diameter of the lower sealing gasket 5. A feed port 51 communicating the feed channel 31 and the avoidance hole 42 is opened on the lower sealing gasket 5. A conical limiting hole 52 is connected to the feed port 51. The small-diameter end of the conical limiting hole 52 is connected to the feed port 51. An exhaust groove 43 is outwardly expanded on the inner side wall of the plug body 4. A second exhaust annular gap is left between the upper sealing gasket 2 and the exhaust groove 43. A sheath 18 is clamped on the valve seat 14. The sheath 18 covers the outside of the bottle body 1 to protect the bottle body 1.

[0017] When it is necessary to fill the perfume into the liquid storage cavity 11 of the bottle body 1, first remove the sheath 18, then hold the bottle body 1 and press the lower gasket 5 against the liquid outlet end of the perfume bottle. The liquid outlet end of the perfume bottle passes through the avoidance hole 42 of the plug body 4 and contacts the feed port 51 under the guiding action of the conical limiting hole 52. Apply force upward, and the liquid outlet end of the perfume bottle pushes the lower gasket 5 and the needle valve 3. After the needle valve 3 overcomes the elastic force of the spring 32, it moves upward along the sealing hole in the upper gasket 2. When the feed channel 31 on the side wall of the needle valve 3 extends over the upper gasket 2 and into the liquid storage cavity 11, squeeze the outer wall of the perfume bottle, and the perfume in the perfume bottle will enter the liquid storage cavity 11 through the liquid outlet end, the feed port 51 and the feed channel 31. Since the needle valve 3 is always in a sealed fit state with the sealing hole in the upper gasket 2, the liquid level height of the perfume entering the liquid storage cavity 11 is lower than the top height of the exhaust pipe 17, so the perfume will not leak into the filling cavity 12. When the perfume enters the liquid storage cavity 11, the air in the liquid storage cavity 11 will be discharged out successively through the exhaust pipe 17, the second exhaust annular gap between the upper gasket 2 and the exhaust groove 43, the first exhaust annular gap and the avoidance hole 42 in the plug body 4. During the filling process, observe the perfume liquid level in the liquid storage cavity 11 through the transparent bottle body 1. When the perfume liquid level in the liquid storage cavity 11 is about to approach the top end of the exhaust pipe 17, stop filling. The lower gasket 5 is separated from the liquid outlet end of the perfume bottle, and the needle valve 3 and the lower gasket 5 reset under the elastic force of the spring 32. The liquid outlet channel 31 on the needle valve 3 is blocked by the upper gasket 2 again, and the lower gasket 5 is sealed and fitted on the plug body 4 again. At this time, the plug body 4 is isolated from the external air, and the exhaust pipe 17 is also isolated from the external air to form an air seal, and the perfume in the liquid storage cavity 11 cannot leak out from the exhaust pipe 17. Finally, reattach the sheath 18 to the valve seat 14 to prevent perfume leakage caused by accidental contact with the lower gasket 5.

[0018] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them.
