Description

Technical Field

[0001] The invention belongs to the technical field of liquid caps, and in particular relates to an environmentally friendly pull-ring bottle cap. Background Art

[0002] At present, the covers of the commonly used liquid bottles in life, such as edible oil bottles, soy sauce bottles, beverage bottles, etc., are all provided with liquid outlets. In order to ensure that the liquid outlets do not leak during transportation or sales, the manufacturers will seal the liquid outlets with sealing parts when leaving the factory. The sealing parts commonly used by various manufacturers at present are to set a sealing piece in the liquid outlet, and set a pull ring on the sealing piece. When in use, the cover body is opened, the pull ring on the sealing piece is pulled, and the sealing piece is torn off and taken out. Because the cover bodies of sesame oil, seasoning oil, etc. are set to be small due to the small capacity of the bottle body in people's daily life, in order to facilitate the outflow of liquid in the bottle, an oil guide pipe is often set on the liquid guide port of the cover body, and a pull ring for pulling the seal on the liquid guide port is set in the oil guide pipe, resulting in the setting size of the pull ring being limited by the diameter of the oil guide pipe. If the inner diameter of the pull ring is too small, the pull ring cannot be hooked by the fingers of the people, and an auxiliary tool is needed to open it, resulting in very inconvenient use. Therefore, when the size of the cover body is certain, how to set the pull ring on the oil guide pipe of the cover body to the largest size has always been a difficult problem in the art.

[0003] Although, Chinese patent document CN201720742019.2 discloses a pull ring liquid outlet cover, refer to Figure 5 As shown, the guide tube 4 is provided with a notch 11 corresponding to the free end of the pull ring 9, so that the user can clamp the free end of the pull ring 9 with fingers and pull the sealing sheet 14 connected to the pull ring 9 out of the liquid outlet to open the liquid outlet. Although this structure solves the problem of opening the pull ring when the pull ring 9 is too small to a certain extent.

[0004] 1. However, for people with less strength, when they use their fingers to clamp the free end of the pull ring 9 to apply force, the fingers are likely to be unable to clamp the free end of the pull ring 9 firmly, causing the fingers to slip away from the free end of the pull ring 9 and unable to pull out the sealing piece 14. Therefore, it is still necessary to make the pull ring large enough so that people can put their fingers into the inner ring of the pull ring 9, so that they can stably hook the pull ring 9 and apply force to pull the sealing piece 14 connected to the pull ring 9 out of the liquid outlet. In addition, a funnel-shaped reflux groove 15 is also provided on the cover body 2 outside the guide tube 4, and an air outlet 6 is provided at the bottom of the funnel-shaped reflux groove 15. The air outlet 6 is used for the residual liquid on the guide tube 4 to flow back into the bottle. Therefore, when the size of the cover body 2 is certain, the funnel-shaped reflux groove 15 is provided on the cover body 2, which occupies a part of the space of the cover body 2, resulting in limited space for setting the guide tube 4 on the cover body 2, making the setting of the guide tube 4 on the cover body 2 account for a small proportion, thereby affecting the size of the pull ring 9 set in the guide tube 4. The diameter of the guide tube 4 can only be increased by setting the diameter of the cover body 2 to be large enough, thereby increasing the diameter of the pull ring 9. However, this will increase the material used for the cover body 2, resulting in increased manufacturing costs. Moreover, after the cover body 2 is enlarged, it is not compatible with the industry standard bottle mouth size, resulting in the need to invest in bottle-related molds and production equipment, which is not conducive to market promotion and use.

[0005] 2. When people pour liquids repeatedly, the residual liquid in the guide tube 4 keeps flowing down to the reflux groove of the cover body 2. Finally, due to the long distance to the air outlet 6 or having flowed to the air outlet 6, but the small diameter of the air outlet 6 makes the liquid reflux rate slow, most of the residual liquid still remains on the reflux groove 8 of the cover body 2. When people pour liquids continuously, the residual liquid will flow out of the outer wall of the cover body 2 from the upper edge of the reflux groove 8, causing pollution of the bottle mouth, dirtying the bottle mouth and the bottle body and causing waste of liquid.

[0006] 3. In addition, a sealing ring 12 is provided inside the buckle cover 1 of the pull ring liquid outlet cover body, which is used to buckle on the guide tube 4 to seal the liquid outlet. When in use, the buckle cover 1 is opened, and the liquid in the bottle can be poured out by pulling out the pull ring 9, the sealing piece 14 and the conical sealing column 7. Since the liquid in the bottle (such as cooking oil, soy sauce, etc.) is often used, the buckle cover 1 will often be opened from the cover body 2 and then covered back on the cover body 2, causing the buckle cover 1 to deform so that the buckle cover 1 cannot be tightly covered with the cover body 2, and a covering gap will appear, which loses the sealing performance. In addition, the sealing ring 12 provided on the buckle cover 1 can only seal the liquid outlet, but cannot seal the air outlet 6, causing the air outlet 6 to be connected to the outside air. Therefore, the solution in the bottle is prone to deterioration when not used for a long time, which endangers the health of diet. In addition, when the liquid in the bottle is not used up at one time after the first use, because it needs to be reused frequently, sometimes the bottle is accidentally caused to fall to the ground, and the liquid will flow out from the air outlet 6 at this time, causing pollution. Summary of the invention

[0007] The purpose of the present invention is to provide an environmentally friendly bottle cap with a pull ring, which aims to solve the problems in the prior art that the diameter of the pull ring arranged in the guide wall is small, which is not conducive to people grasping the free end of the pull ring to pull out the sealing piece connected to the pull ring, and the diameter of the air outlet is small and the distance of the reflux groove is too long, which makes the liquid reflux rate slow, and the liquid cannot be used up at one time and can be kept fresh for repeated use for a long time, and the technical problem of sealing the liquid when the bottle falls to the ground during use.

[0028] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0029] In the embodiments of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific circumstances.

[0030] In one embodiment of the present invention, referring to Figure 1 and Figure 2 , a ring-pull environmentally friendly bottle cap is provided, comprising a buckle cover 1 and a cover body 2; the buckle cover 1 is covered on the cover body 2. A reflux groove 5 is provided in the cover body 2, a sealing platform 4 is provided in the middle of the reflux groove 5, and a liquid outlet 6 is provided in the sealing platform 4. A guide wall 8 is provided around part of the periphery of the sealing platform 4, and the liquid outlet 6 is arranged close to the guide wall 8, and the guide wall 8 has an upper liquid guide port 81 and a side opening 82. A sealing sheet 7 is also provided on the liquid outlet 6, one end of a ring pull 9 is connected to the sealing sheet 7 through a connecting piece 91, and the other end of the ring pull 9 is a free end 92 and the free end 92 extends from the side opening 82.

[0031] Further, refer to Figure 2 , the reflux groove 5 is a funnel-shaped reflux groove, and the funnel-shaped reflux groove has the function of quickly gathering the residual liquid on the reflux groove 5. That is, when people pour liquid once or repeatedly, the residual liquid on the guide wall 8 keeps flowing down to the funnel-shaped reflux groove of the cover body 2, and the liquid quickly gathers downward along the funnel-shaped reflux groove. Due to the large diameter of the liquid outlet 6, the liquid quickly flows back into the bottle through the liquid outlet 6. The funnel-shaped reflux groove improves the reflux efficiency of the residual liquid and ensures that the bottle mouth is clean and beautiful. Therefore, referring to Figure 5 The structure of the present invention can effectively solve the technical problems in the prior art that when people pour liquid repeatedly, the residual liquid in the guide tube 4 keeps remaining and flows to the reflux groove of the cover body 2, and finally most of the residual liquid remains on the reflux groove 8 of the cover body 2 due to the long distance to the air outlet 6 or has flowed to the air outlet 6, but the diameter of the air outlet 6 is small, so that the liquid reflux rate is slow. At this time, most of the residual liquid still remains on the reflux groove 8 of the cover body 2. When pouring liquid continuously, it will flow out of the outer wall of the cover body 2 from the upper edge of the reflux groove 8, causing the bottle mouth to be polluted, the bottle mouth and the bottle body to be dirty, and causing liquid waste.

[0032] Furthermore, the guide wall 8 is an arc-shaped guide wall, so that the guide wall 8 can completely receive the liquid poured out from the liquid outlet 6 and guide the poured liquid so that the liquid flows out from the liquid outlet 81 smoothly and smoothly along the guide wall 8.

[0033] Specifically, in the present embodiment, the liquid outlet 6 is a "semi-circular" liquid outlet, the arc end 61 of the "semi-circular" liquid outlet is located inside the guide wall 8, and the straight end 62 of the "semi-circular" liquid outlet extends out of the side opening 82. When pouring liquid, the liquid can smoothly flow out of the liquid guide port 81 through the guide wall 8. The residual liquid on the reflux groove 5 quickly gathers downward along the funnel-shaped reflux groove. Since the straight end 62 of the "semi-circular" liquid outlet extends out of the side opening 82, the distance for the residual liquid to flow to the liquid outlet 6 is shortened, and the residual liquid gathered on the sealing platform 4 directly flows back into the bottle from the liquid outlet 6. Therefore, the residual liquid on the reflux groove 5 can flow back into the bottle from the liquid outlet 6 more quickly.

[0034] In another embodiment of the present invention, referring to Figure 2-Figure 4 The sealing platform 4 of the pull-ring environmentally friendly bottle cap is also provided with a funnel groove 10, and the funnel groove 10 is located on one side of the liquid outlet 6; the lowest part of the funnel groove 10 is provided with a reflux hole 11, and the reflux hole 11 is provided with a sealing column 12. When in use, the sealing column 12 is pulled out, and when the liquid is poured out from the guide wall 8 once or repeatedly, the residual liquid on the guide wall keeps remaining and flows to the reflux groove 5 of the cover body 2, and the residual liquid quickly refluxes downward along the reflux groove 5, and the residual liquid can flow back into the bottle from the liquid outlet 6 and the reflux hole 11 of the funnel groove 10 at the same time, so that the residual liquid reflux rate is faster and the reflux effect is better. If people do not control the amount of liquid to be poured, the liquid is poured out too quickly and a large amount of liquid flows back to the flow channel 5, even a large amount of liquid can quickly flow back into the bottle from the liquid outlet 6 and the reflux hole 11, so that a large amount of residual liquid can be quickly refluxed in a short time, avoiding the contamination and turbidity of the cover body 2 caused by residual liquid hanging outside or poor reflux, and keeping the bottle mouth clean and hygienic. Due to the structure of the liquid outlet 6 and the reflux hole 11, when containers equipped with the pull ring environmental protection bottle cap structure are filled and poured, the filling and pouring can be completed well without spilling out of the cover body 2.

[0035] Specifically, in this embodiment, the funnel groove 10 is a "semicircular" funnel groove; a partition 18 is formed between the straight end of the "semicircular" funnel groove and the straight end 62 of the "semicircular" liquid outlet, and the partition 18 has a diversion function, so that the residual liquid can flow into the liquid outlet 6 and the funnel groove 10 along both sides of the partition respectively.

[0036] Furthermore, due to the arc-shaped structure of the guide wall 8, it can be set on the cover body 2 to the maximum extent, and the funnel groove 10 is set in the sealing platform 4 will not affect the setting space of the guide wall 8 on the cover body 2, so that the guide wall 8, the liquid outlet 6, and the funnel groove 10 are more compactly and reasonably arranged on the cover body 2. That is, when the size of the cover body 2 is certain, since the guide wall 8 can be set on the cover body 2 to the maximum extent, the pull ring 9 can also be set on the cover body 2 to the maximum extent. In this way, the diameter of the pull ring 9 can be increased to a suitable value without increasing the diameter of the cover body 2. In this way, people can easily pass their fingers through the inner ring of the pull ring 9 and stably hook the pull ring 9 to apply force. Since the guide wall 8 has a side opening 82 structure, people will not be blocked by the guide wall 8 during the force application process and can more easily apply force to the pull ring 9. By pulling the sealing piece 7 connected to the pull ring 9 out of the liquid outlet 6, the liquid in the bottle can be poured out from the liquid outlet 6 for use. Therefore, the arc-shaped structure of the guide wall 8 can well solve the problem that the pull ring is difficult to make larger in the prior art.

[0037] The ring-pull environmentally friendly bottle cap provided by the embodiment of the present invention has one of the following technical effects: when in use, when people pour liquid for multiple times in succession, the residual liquid on the guide wall 8 keeps remaining and flows to the reflux groove 5 of the cover body 2, and the liquid flowing to the reflux groove 5 of the cover body 2 will quickly gather downward along the reflux groove 5, and a part of the residual liquid will flow back into the bottle through the liquid outlet 6, and the remaining part of the residual liquid will pass through the conical sealing groove 14 on the sealing platform 4, and finally flow into the reflux hole 11 of the funnel 10 and flow into the bottle, so as to prevent the residual liquid on the reflux groove 5 of the cover body 2 from being continuously poured. The liquid will flow out of the outer wall of the cover body 2 from the upper edge of the reflux groove 5, causing pollution to the bottle mouth. The liquid outlet 6 arranged on the cover body 2 can realize that part of the liquid remaining on the guide wall 8 flows back to the inner body of the bottle through the liquid outlet 6. Since the liquid outlet 6 has a large diameter and is short from the guide wall 8, the reflux rate is faster than that from the reflux hole 11. The remaining part of the residual liquid passes through the conical sealing groove 14 on the sealing platform 4, and finally flows into the reflux hole 11 of the funnel groove 10 and flows into the bottle. The setting of the double reflux mechanism can effectively ensure the cleanliness and beauty of the bottle mouth and the bottle body, and reduce liquid waste. Due to the structure of the guide wall 8, it is set on the cover body 2 to the maximum extent and will not be affected by the setting of the funnel groove 10 on the cover body 2. That is, when the size of the cover body 2 is certain, since the guide wall 8 can be set on the cover body 2 to the maximum extent, the pull ring 9 can also be set on the cover body 2 to the maximum extent. In this way, the diameter of the pull ring 9 can be increased to a suitable value without increasing the diameter of the cover body 2. People can easily pass their fingers through the inner ring of the pull ring 9 and stably hook the pull ring to apply force. Since the guide wall 8 has a side opening 82 structure, and people will not be blocked by the guide wall 8 during the force application process, they can more easily apply force to the pull ring, pull the sealing piece 7 connected to the pull ring 9 out of the liquid outlet 6, and pour the liquid in the bottle from the liquid outlet 6 for use.

[0038] In another embodiment of the present invention, referring to Figure 2-Figure 4 , the sealing platform 4 of the pull-ring environmentally friendly bottle cap is circular. A conical sealing groove 14 is provided at the connection between the sealing platform 4 and the reflux groove 5. A sealing ring 13 is convexly provided inside the buckle cover 1, and a conical sealing platform 15 is provided at the open end of the sealing ring 13. When the buckle cover 1 and the cover body 2 are covered, the conical sealing platform 15 extends into the conical sealing groove 14 and seals against the conical sealing groove 14, so that the funnel groove 10 and the liquid outlet 6 are sealed in the sealing ring 13 to protect the liquid in the bottle from deterioration. Even if the buckle cover 1 needs to be opened from the cover body 2 and then covered on the cover body 2 frequently when using the cover body liquid, causing the buckle cover 1 to deform so that the buckle cover 1 cannot be tightly covered with the cover body 2 and a covering gap appears, and the sealing performance is lost, it does not affect the sealing ring 13 to tightly seal the funnel groove 10 and the liquid outlet 6 therein, and can still isolate the liquid in the bottle from the outside air and protect the liquid in the bottle from deterioration. In addition, when the liquid in the bottle is not used up at one time after the first use, the snap cover 1 will be closed on the cover body 2 to seal and store the liquid for secondary use. Due to the need for frequent reuse, the bottle may be accidentally touched and fall to the ground. At this time, even if the liquid flows out from the liquid outlet 6 and the reflux hole 11, due to the sealing and blocking effect of the sealing ring 13, when people correct the bottle, the liquid flowing into the sealing ring 13 will flow back into the bottle through the liquid outlet 6 and the reflux hole 11, avoiding contamination of the bottle cap.

[0039] Furthermore, the height of the sealing column 12 should be lower than the height of the guide wall 8, so as to facilitate the closing of the buckle cover 1 and the cover body 2 and prevent the sealing column 12 from hitting the buckle cover 1 and causing the buckle cover 1 and the cover body 2 to not close tightly. If the sealing ring 13 is too high, it will not be able to seal the funnel groove 10 and the liquid outlet 6, causing the solution in the bottle to deteriorate and endangering dietary health.

[0040] In another embodiment of the present invention, referring to Figure 2-Figure 4 The cover body 2 of the pull-ring environmentally friendly bottle cap is connected to the side wall of one end of the buckle cover 1 through the connecting belt 3, and the other end of the buckle cover 1 is a free end. An opening groove 16 is also provided on the outer side wall of the buckle cover 1 away from the connecting belt 3. The opening groove 16 facilitates the user to buckle the buckle cover 1 on the cover body 2 or open it from the cover body 2, which is convenient for use.

[0041] Furthermore, the upper outer side wall of the cover body 2 is provided with a first arc-shaped convex portion 22, and the lower inner side wall of the buckle cover 1 is provided with a second arc-shaped convex portion 17. When the buckle cover 1 and the cover body 2 are covered, the second arc-shaped convex portion 17 cooperates with the first arc-shaped convex portion 22 to make the buckle cover 1 stably buckled on the cover body 2.

[0042] The rest of this embodiment is the same as the first embodiment. The features not explained in this embodiment are all based on the explanations in the first embodiment and will not be described in detail here.

[0043] The pull-ring environmentally friendly bottle cap of the present invention is operated and used by the user opening the snap cover 1 covered on the cover body 2, then passing a finger through the ring hole of the pull ring 9, and then forcefully pulling the pull ring 9, which tears off the sealing sheet 7 from the liquid outlet 6 through the connecting piece 91, and then pulls out the sealing column 12 provided on the reflux hole 11, and then the solution in the bottle can be used. After use, the snap cover 1 is snapped on the cover body 2.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
