Description

Technical Field

[0001] This utility model relates to the field of liquid plastic container technology, and in particular to a fragrance bottle cap. Background Technology

[0002] In existing drinking water products, if a flavor is desired, pre-mixed flavorings are added to the water to create a beverage. However, if one wants to drink flavored purified water without ingesting flavorings or other substances, appropriately flavored water containers can be used.

[0003] Scented water containers are made by embedding a fragrance ring at the mouth or cap of the container, so that the water is infused with fragrance when drinking from the container.

[0032] Please see Figures 1 to 5 This embodiment provides a scented bottle cap that can be installed on a water container, allowing users to fill the container with water and obtain a fragrance while drinking. The scented bottle cap of this embodiment includes a cap base 1 and a cap body 2.

[0033] The cap 1 has a suction nozzle 111. The cap 1 contains a liquid outlet channel 1212, a fragrance source storage chamber 101, a fragrance temporary storage chamber 102, and a fragrance channel 1211. One end of the liquid outlet channel 1212 has a liquid outlet 12121 exposed at the suction nozzle 111. When the fragrance bottle cap is installed on the bottle body 4, the liquid in the bottle can enter the liquid outlet channel 1212 and exit from the liquid outlet 12121. A silicone valve 103 is installed in the liquid outlet channel 1212 to control the liquid flow rate. When the user sucks liquid from the suction nozzle 111, the silicone valve 103 opens to increase the liquid flow rate. In its natural state, the silicone valve 103 closes, shutting off the liquid outlet channel 1212. Specifically, the silicone valve 103 is a cross-shaped silicone valve 103.

[0034] The fragrance source storage chamber 101 is used to store fragrance substances, which may be fragrance strips or fragrance granules. The fragrance temporary storage chamber 102 is connected to the fragrance source storage chamber 101 through a vent 1221, so that the fragrance gas in the fragrance source storage chamber 101 can enter the fragrance temporary storage chamber 102 through the vent 1221. The fragrance temporary storage chamber 102 is used to store fragrance gas. One end of the fragrance channel 1211 is exposed at the mouthpiece 111, and the other end is connected to the fragrance temporary storage chamber 102. The cover 1 is also provided with an air inlet 110 that connects to the fragrance source storage chamber 101. The air inlet 110 is used to connect the fragrance source storage chamber 101 with the outside atmosphere, thereby balancing the air pressure of the fragrance source storage chamber 101, the fragrance temporary storage chamber 102 and the outside atmosphere, so that the fragrance can be smoothly delivered to the top of the mouthpiece 111 through the fragrance channel 1211.

[0035] When the cover 2 is placed on the cover 1, the liquid outlet 12121, one end of the fragrance channel 1211 and the air inlet 110 are all sealed by the cover 2.

[0036] As can be seen from the above configuration, the fragrance bottle cap of this application can be installed on the bottle body. When the cap 2 is opened, the air inlet 110 is connected to the outside atmosphere. When the user sucks on the mouthpiece 111, not only can liquid be drawn in from the liquid outlet 12121, but negative pressure is also generated in the fragrance channel 1211, allowing outside air to enter the fragrance source storage chamber 101 from the air inlet 110. This air then carries the fragrance molecules in the fragrance source storage chamber 101 into the fragrance temporary storage chamber 102, and together they are drawn in by the user from the top of the mouthpiece 111 along the fragrance channel 1211, producing a fragrance sensation. In other words, when the user sucks, the liquid and fragrance can enter the mouth together.

[0037] When the cover 2 is placed on the cover 1, the cover 2 and the cover 1 are tightly connected, so that the liquid outlet 12121, one end of the fragrance channel 1211 and the air inlet 110 are all sealed. In this way, the fragrance molecules in the fragrance storage chamber 102 will not enter the liquid outlet 12121 or the liquid outlet channel 1212 and contaminate the liquid, which effectively blocks the spread of fragrance.

[0038] This application differs from most existing scented straw water containers in principle. Most scented water containers have an air channel connecting the fragrance tank and the water channel, causing the water and fragrance to mix together before entering the mouth. This may cause the water to enter the fragrance tank along the air channel, resulting in water accumulation in the fragrance tank and thus affecting the fragrance quality.

[0039] Using the fragrance-filled water container of this application, the water flow and fragrance do not meet before entering the mouth, thus avoiding this phenomenon and providing a continuous, high-quality, and healthy fragrance supply. This is one of the characteristics of the fragrance-filled water container of this application.

[0040] Furthermore, when the nozzle 111 is drawing liquid, if some liquid accidentally enters the fragrance channel 1211, this liquid will not directly enter the fragrance source storage chamber 101 and contaminate the fragrance substance. Instead, it will enter the fragrance temporary storage chamber 102 through the fragrance channel 1211 and be stored there. In other words, the fragrance temporary storage chamber 102 in this embodiment has a water storage function, which allows the return water to be stored, thereby preventing water from mixing with the fragrance substance and causing the fragrance substance to deteriorate. Therefore, the functionality and practicality of this product can be significantly improved.

[0041] In this embodiment, the fragrance source storage cavity 101 is arranged around the outer periphery of the fragrance temporary storage cavity 102, and the fragrance temporary storage cavity 102 is arranged around the outer periphery of the liquid outlet channel 1212, so that the fragrance gas can circulate around the fragrance source storage cavity 101 once before entering the fragrance temporary storage cavity 102, thereby increasing the fragrance concentration.

[0042] In the horizontal direction, the vent 1221 is positioned higher than the bottom of the fragrance storage chamber 102, which can effectively prevent moisture that accidentally enters the fragrance storage chamber 102 from entering the fragrance source storage chamber 101 through the vent 1221.

[0043] Specifically, the cover 1 includes an outer cover 11 and an inner cover 12. The inner cover 12 is disposed inside the outer cover 11 to enclose the fragrance source storage cavity 101 and the fragrance temporary storage cavity 102 together with the outer cover 11. This arrangement facilitates the placement of fragrance substances. By separating the outer cover 11 and the inner cover 12, the fragrance substances can be placed into the fragrance source storage cavity 101. The inner cover 12 includes a tubular portion 121. The liquid outlet channel 1212 is formed inside the tubular portion 121. The liquid outlet 12121 of the liquid outlet channel 1212 is formed at the top end of the tubular portion 121. The fragrance channel 1211 is axially disposed in the tube wall of the tubular portion 121. One end of the fragrance channel 1211 extends to the top end of the tubular portion 121, and the other end extends to the outer wall of the tubular portion 121.

[0044] The suction nozzle 111 is formed on the outer cover 11. The suction nozzle 111 is arranged around the outer periphery of the tubular portion 121. The top end of the tubular portion 121 is exposed at the top end of the suction nozzle 111. The air inlet 110 is provided on the outer cover 11.

[0045] Specifically, the inner cover 12 further includes a first annular portion 122 and a second annular portion 123. The first annular portion 122 is disposed around the outer periphery of the tubular portion 121, and the second annular portion 123 is disposed around the outer periphery of the first annular portion 122. The first annular portion 122 abuts against the inner wall of the outer cover 11 to enclose the fragrance storage cavity 102, and the second annular portion 123 abuts against the inner wall of the outer cover 11 to enclose the fragrance source storage cavity 101. The first annular portion 122 has a vent hole 1221.

[0046] Preferably, the bottom of the inner cap 12 is further provided with a sealing ring 124 that extends into the bottle body. This improves the sealing performance between the inner cap 12 and the bottle body.

[0047] Preferably, in this embodiment, the inner cap 12 and the outer cap 11 are snap-fitted together. The bottom of the outer cap 11 is provided with an internal thread that connects to the bottle body. The cap body 2 is connected to the outer cap 11 via a connecting ring 21. This facilitates the installation of the inner cap 12. Specifically, the outer periphery of the second annular portion 123 is provided with a snap-fit ​​groove, and the inner sidewall of the outer cap 11 is provided with a snap-fit ​​ring that snaps into the snap-fit ​​groove.

[0048] To improve sealing performance, the outer cover 11 and the inner cover 12 are connected by an interference fit.

[0049] Preferably, in this embodiment, the cover 2 is provided with a first sealing post 22, a first sealing surface 23, and a second sealing surface 24 on the side facing the cover base 1. The first sealing post 22 is used to close the liquid outlet 12121, the first sealing surface 23 is used to seal one end of the fragrance channel 1211, and the second sealing surface 24 is used to seal the air inlet 110. This arrangement improves the overall sealing performance and further prevents the mixing of liquid and fragrance.

[0050] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
