Abstract
Description
Technical Field
[0001] This utility model relates to the field of bottle caps, and more particularly to a combination cap. Background Technology
[0002] Currently, many beverages are packaged in bottles, and these bottles typically have open openings. This open opening presents a problem: consumers may choke when drinking rapidly due to the large opening. Furthermore, the wide opening is unsuitable for careful sipping. To address this, patent publication CN114803127A discloses a bottle cap with an adjustable opening size. However, this cap only has one channel, preventing outside air from entering the bottle when the user drinks through it. This creates negative pressure inside the bottle, preventing the beverage from flowing out smoothly. Utility Model Content
[0003] To address the aforementioned problems, this invention proposes a combined cap with an air hole and a liquid hole at both ends of the baffle. When drinking beverages, the liquid hole is located at the bottom and the air hole at the top. The beverage flows out through the liquid hole and the gas enters through the air hole, ensuring that there is no negative pressure inside the bottle and that the beverage can flow out smoothly.
[0004] The technical solution adopted by this utility model is as follows:
[0005] A combined cover includes a connecting cylinder and an outer cover. One end of the connecting cylinder is provided with an internal connecting thread, and the other end of the connecting cylinder is provided with an external connecting thread. The outer cover is provided with a mating thread that mates with the external connecting thread. One end of the connecting cylinder is provided with a baffle plate, which has a liquid hole and an air hole, located at opposite ends of the baffle plate.
[0006] In this type of cap assembly, the internal connecting thread on the connecting cylinder is used to screw onto the bottle neck. The outer cap, through its own mating thread, engages with the external thread on the connecting cylinder to seal the bottle neck. When the bottle neck is properly sealed, the connecting cylinder is mounted on the bottle neck (when in place, the bottle neck engages with the stepped annular groove inside the connecting cylinder), and the outer cap is mounted on the connecting cylinder. To open the cap, unscrew the outer cap from the connecting cylinder. The beverage can then be consumed through the connecting cylinder. One end of the connecting cylinder is blocked by a baffle plate. When drinking, this ensures that the liquid outlet is below and the vent is above, allowing the beverage to flow out through the liquid outlet and the gas to enter through the vent. This prevents negative pressure inside the bottle, ensuring smooth drinking.
[0007] In summary, in this type of combined cap, air holes and liquid holes are respectively opened at both ends of the baffle. When drinking beverages, the liquid hole is located at the bottom and the air hole is located at the top. Beverages flow out from the liquid hole and gas enters from the air hole, ensuring that there is no negative pressure inside the bottle and that the beverages can flow out smoothly.
[0008] In this type of cap, when drinking beverages, the beverage flows out through the liquid hole, and the diameter of the liquid hole is much smaller than the diameter of the bottle mouth. Therefore, when drinking beverages through the liquid hole, the amount of beverage flowing out is relatively small, and there will be no choking phenomenon, and it is convenient to savor the beverage.
[0009] Specifically, in this assembly cover, the outer cover includes a top piece and a ring cylinder, which are integrally formed and threaded onto the inner wall of the ring cylinder.
[0010] Optionally, the baffle is provided with a concave shape, which forms an air passage with the inner wall of the connecting cylinder. The air passage is connected to the air hole, and a guide slope is provided on one side of the baffle.
[0011] The baffle is set at the opening of the connecting cylinder, and part of the baffle is recessed into the interior of the connecting cylinder. The recess and the inner wall of the connecting cylinder form an air passage. The air passage is circular. Due to the recess on the baffle, a guide slope is formed on one side of the baffle. When the air hole is located above and the liquid hole is located below, the presence of the guide slope can prevent the liquid from overflowing into the air passage and guide the liquid to the liquid hole.
[0012] Optionally, an anti-theft ring is provided on the outer cover.
[0013] The anti-theft ring is specifically set on the ring cylinder. The anti-theft ring and the top plate are located at opposite ends of the ring cylinder. When the outer cover is unscrewed from the connecting sleeve, the anti-theft ring will fall off the outer cover and remain on the connecting cylinder.
[0014] Optionally, a sealing gasket is provided between the outer cover and the baffle.
[0015] Optionally, the sealing gasket is bonded to the outer cover.
[0016] The sealing gasket is fixed to the top plate of the outer cover by ultrasonic welding. The sealing gasket includes, but is not limited to, silicone sealing gaskets.
[0017] Optionally, the outer cover is made of polyethylene.
[0018] The outer cover can be made of high-density polyethylene injection molding.
[0019] Optionally, the connecting cylinder is made of polypropylene.
[0020] Optionally, the baffle is made of polypropylene.
[0021] The beneficial effects of this utility model are: air holes and liquid holes are respectively opened at both ends of the baffle. When drinking beverages, the liquid hole is located at the bottom and the air hole is located at the top. The beverage flows out from the liquid hole and the gas enters from the air hole, ensuring that there is no negative pressure inside the bottle and the beverage can flow out smoothly.

[0031] As attached Figure 1 Appendix Figure 2 Appendix Figure 3 and appendix Figure 4 As shown, a combined cover includes a connecting cylinder 4 and an outer cover. One end of the connecting cylinder 4 is provided with an internal connecting thread 402, and the other end of the discharge cylinder is provided with an external connecting thread 401. The outer cover is provided with a mating thread that mates with the external connecting thread 401. One end of the connecting cylinder 4 is provided with a baffle 3. The baffle 3 has a liquid hole 303 and an air hole 302, which are located at opposite ends of the baffle 3.
[0032] In this type of cap assembly, the internal connecting thread 402 on the connecting cylinder 4 is used to screw onto the bottle neck. The outer cap, through its own mating thread, engages with the external thread on the connecting cylinder 4 to seal the bottle neck. When the connecting cylinder 4 is installed on the bottle neck (when installed in place, the bottle neck is locked in place by the stepped annular groove 403 inside the connecting cylinder 4, and the stepped annular groove 403 locks the bottle neck, fixing the entire connecting cylinder 4 firmly to the bottle neck and preventing it from being unscrewed), the outer cap is installed on the connecting cylinder 4. To open the cap, the outer cap is unscrewed from the connecting cylinder 4, allowing the beverage to be consumed through the connecting cylinder 4. One end of the connecting cylinder 4 is blocked by the baffle 3. When drinking, the liquid hole 303 is positioned below, and the vent 302 is positioned above. The beverage can flow out through the liquid hole 303, while gas can enter through the vent 302, ensuring that there is no negative pressure inside the bottle and allowing for smooth consumption.
[0033] In summary, in this type of combined cap, air holes 302 and liquid holes 303 are respectively opened at both ends of the baffle 3. When drinking beverages, the liquid hole 303 is located at the bottom and the air hole 302 is located at the top. Beverages flow out from the liquid hole 303 and gas enters from the air hole 302, ensuring that there is no negative pressure inside the bottle and that beverages can flow out smoothly.
[0034] In this type of cap, when drinking beverages, the beverages flow out through the liquid hole 303. Since the diameter of the liquid hole 303 is much smaller than the diameter of the bottle mouth, the amount of beverages flowing out when drinking through the liquid hole 303 is relatively small, so there will be no choking phenomenon, and it is convenient to savor the beverage.
[0035] Specifically, in this assembly cover, the outer cover includes a top piece 101 and a ring cylinder 102. The top piece 101 and the ring cylinder 102 are integrally formed and are threaded onto the inner wall of the ring cylinder 102.
[0036] As attached Figure 1 Appendix Figure 2 Appendix Figure 3 and appendix Figure 4 As shown, the baffle 3 is provided with an indentation 301, which forms an air passage 34 with the inner wall of the connecting cylinder 4. The air passage 34 is connected to the air hole 302, and a guide slope 304 is provided on one side of the baffle 3.
[0037] The baffle 3 is set at the opening of the connecting cylinder 4, and a part of the baffle 3 is recessed into the interior of the connecting cylinder 4. An air passage 34 is formed between the recess 301 and the inner wall of the connecting cylinder 4. The air passage 34 is circular. Due to the recess 301 on the baffle 3, a guide slope 304 is formed on one side of the baffle 3. When the air hole 302 is located above and the liquid hole 303 is located below, the presence of the guide slope 304 can prevent liquid from overflowing into the air passage 34 and guide the liquid to the liquid hole 303.
[0038] As attached Figure 1 Appendix Figure 2 Appendix Figure 3 and appendix Figure 4 As shown, an anti-theft ring 2 is provided on the outer cover.
[0039] Specifically, the anti-theft ring 2 is set on the ring cylinder 102. The anti-theft ring 2 and the top piece 101 are located at the two ends of the ring cylinder 102 respectively. When the outer cover is unscrewed from the connecting sleeve, the anti-theft ring 2 will fall off the outer cover and remain on the connecting cylinder 4.
