Description

Technical Field

[0001] The utility model relates to the technical field of bottle caps, in particular to a pull-ring sealing cap. Background Art

[0002] To facilitate pouring, laundry detergent bottles typically have separate caps: an upper cap seals the bottle, while a lower cap connects to the bottle body. The lower cap has a liquid outlet, and a drainage tube is positioned above the outlet to guide the liquid. However, due to the bumpy conditions often encountered during transportation, the liquid can easily flow out of the lower cap's outlet, overflowing between the upper and lower caps and contaminating the inner wall of the upper cap. If the upper and lower caps become loose, the liquid can easily leak.

[0003] To address this issue, conventional technology typically installs a seal at the liquid outlet, providing a secondary seal to prevent liquid leakage during transport. The seal is removed before use, allowing the laundry detergent to drain normally. However, due to the small size of the liquid outlet and the height of the drainage tube, it's difficult to reach into the tube and apply force to remove the seal, making the tearing process difficult and laborious.

[0027] The technical solution protected by the present utility model is described in detail below with reference to the accompanying drawings.

[0028] like Figure 1-3 As shown, the present application proposes an easy-to-tear pull-ring sealing cap, which includes a cap body 1 and a partition 11 disposed within the cap body 1. The partition 11 is provided with a sunken section 2 and a drainage tube 4. The sunken section 2 is provided with an opening 21, and a pull-ring device 3 is provided on the opening 21 in a tearable manner. The cap body 1 is used to connect with the bottle body, and the laundry liquid is poured out from the opening 21. The drainage tube 4 is used to guide the laundry liquid during pouring. The pull-ring device 3 is used to prevent leakage of the laundry liquid during transportation and to seal the opening 21.

[0029] like Figure 1-3 As shown, the cover body 1 has a cylindrical inner cavity, and the partition 11 is obliquely arranged in the inner cavity. In this embodiment, the cover body 1 and the partition 11 are integrally formed. The partition 11 divides the inner cavity of the cover body 1 into an upper chamber 12 and a lower chamber 13. The lower chamber 13 is used to communicate with the inner cavity of the bottle body. The inner wall of the lower chamber 13 has a threaded structure connected to the bottle body, so that the cover body 1 can be set on the bottle body by thread locking. Preferably, an annular groove is provided between the lower end surface of the partition 11 and the inner wall of the cover body 1, and a sealing ring 5 is arranged in the annular groove. When the cover body 1 is threadedly locked on the bottle body, the sealing ring 5 improves the sealing of the connection between the cover body 1 and the bottle body, preventing liquid from leaking from the connection between the cover body 1 and the bottle body.

[0030] like Figure 1-3As shown, the sinking interval 2 is correspondingly arranged on the partition 11, and the sinking interval 2 includes an opening 21 and a guide structure 22 arranged around the opening 21. The opening 21 includes a liquid outlet 211 and a reflux portion 212 that are interconnected. The reflux portion 212 is located on the lower side of the liquid outlet 211, and the area of ​​the liquid outlet 211 is larger than the area of ​​the reflux portion 212. The drainage tube 4 is correspondingly arranged around the sinking interval 2 and placed in the upper chamber 12. The middle of the end of the drainage tube 4 away from the partition 11 protrudes from the upper edge of the cover body 1, and is formed with an arc-shaped annular edge with low sides and high middle, which helps to drain the liquid. A notch 41 is provided in the drainage tube 4 corresponding to the reflux portion 212, which is convenient for a person to reach into the notch 41 to pull the pull ring device 3, and the residual liquid can flow back into the bottle body from the reflux portion 212. Preferably, the horizontal width D1 of the notch 41 is no less than 18 mm to ensure that a single finger can pass through it. The horizontal width D1 of the notch 41 does not exceed the maximum diameter of the liquid outlet 211 to ensure proper drainage when pouring the laundry liquid. The laundry liquid pours out of the liquid outlet 211, and the drainage tube 4 guides the liquid. The laundry liquid remaining on the outer wall of the drainage tube 4 flows back into the bottle through the lowered reflux portion 212.

[0031] like Figure 1-3 As shown, the side of the guide structure 22 near the opening 21 is tilted toward the lower chamber 13 to assist in the backflow of liquid from the inner wall of the drainage tube 4. The width of the guide structure 22 gradually increases from the end of the liquid outlet 211 away from the return portion 212 toward the return portion 212, causing the inner diameter of the liquid outlet 211 to gradually decrease toward the return portion 212. This controls the amount and speed of liquid discharge when the bottle is tilted at a large angle. Furthermore, the guide structure width D2 corresponding to the end of the liquid outlet 211 away from the return portion 212 ranges from 0 to 3 mm to ensure smooth and efficient liquid discharge when the bottle is tilted at a relatively low angle.

[0032] like Figure 1-3 As shown, the pull ring device 3 is detachably connected to the interior of the opening 21 and is used to seal the opening 21. The pull ring device 3 includes: a sealing sheet 31 disposed within the opening 21; a pull ring 32 fixed to the side of the sealing sheet 31 near the reflux portion 212; and a tear layer 33 disposed between the outer periphery of the sealing sheet 31 and the inner wall of the opening 21. When a force is applied to the pull ring 32, the tear layer 33 breaks, separating the sealing sheet 31 from the opening 21, thereby connecting the upper chamber 12 with the lower chamber 13.

[0033] like Figure 1-3As shown, the thickness of the tear layer 33 gradually increases from the return portion 212 toward the liquid outlet portion 211. The tear layer 33 is thinner near the return portion 212, allowing a person to break the tear layer 33 with minimal force when sealed, saving manpower. The tear layer 33 is thicker away from the return portion, providing overall sealing strength for the pull ring device 3 and ensuring a tight seal.

[0034] like Figure 1-3 As shown, the pull ring 32 includes a connecting portion 321 and an annular portion 322. The connecting portion 321 is fixed vertically to the sealing sheet 31, and the annular portion 322 is disposed at the end of the connecting portion 321 away from the sealing sheet 31. The end of the annular portion 322 away from the connecting portion 321 is tilted away from the sealing sheet 31. Preferably, the vertical height difference H1 between the end of the annular portion away from the connecting portion and the corresponding sealing sheet below is not less than 10 mm, to ensure that the end of the user's finger can directly reach under the annular portion 322, pull the annular portion 322, and then apply an upward pulling force.

[0035] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
