Description

Technical Field

[0001] The utility model relates to the technical field of tear-off caps, and specifically, to a tear-off strip structure for a plastic bucket tear-off cap. Background Art

[0002] A tear-off cap is a common type of packaging cap, which generally has the following characteristics: A tear-off cap is generally designed to be opened by manual tearing, which is relatively convenient to use. In terms of material, a tear-off cap can be made of plastic (such as PET, etc.), which has certain flexibility and durability and is easy to open without additional tools. It has a certain degree of sealing performance and can protect the items inside the packaging. The tear-off cap has so many advantages, which is inseparable from the tear-off strip provided inside the cap body.

[0003] After retrieval, a tear-off connected cap disclosed in the publication number CN219340302U is roughly described as including an upper cap, a tear-off ring, and a fixing ring. The fixing ring is fixedly connected to the bottle mouth through buckles evenly distributed on the inner end face. There are two connecting ribs between the upper cap and the fixing ring, and a fixing rib is arranged between the connecting ribs. Both ends of the fixing rib are respectively connected to the tear-off ring and the fixing ring. Symmetrically distributed grooves are arranged on the inner end face of the tear-off ring, and a first protrusion matching the upper groove of the tear-off ring is arranged on the outer end face of the upper cap. A second protrusion matching the lower groove of the tear-off ring is arranged on the outer end face of the fixing ring. The connected cap proposed by the utility model can replace the existing cap that is used separately from the bottle, and can fix the upper cap at any opening angle position, which is convenient for users. During use, the upper cap is always connected to the fixing ring through the connecting ribs. Without affecting the use, it can prevent the upper cap from being lost and is also convenient for the recycling of the bottle.

[0004] Although the above solution can make the upper cap open at any angle and prevent the upper cap from being lost, in actual use, there is often a situation where the liquid in the bucket has not been used up and still needs to be sealed. Simply using the bucket cap for sealing, the grooves at the tear-off strip tearing position of the bucket cap are prone to being contaminated with dust or dirt. When the bucket cap is opened next time, the dirt is likely to fall into the liquid in the bucket and cause pollution, or some special liquids may cause air to enter the bucket when the bucket cap is not fully tightened, resulting in liquid pollution. Content of the Utility Model

[0005] The purpose of the utility model is to provide a tear-off strip structure for a plastic bucket tear-off cap, which solves the problems in the prior art that in actual use, there is often a situation where the liquid in the bucket has not been used up and still needs to be sealed. Simply using the bucket cap for sealing, the grooves at the tear-off strip tearing position of the bucket cap are prone to being contaminated with dust or dirt. When the bucket cap is opened next time, the dirt is likely to fall into the liquid in the bucket and cause pollution, or some special liquids may cause air to enter the bucket when the bucket cap is not fully tightened, resulting in liquid pollution.

[0006] The utility model provides the following technical solution: A pull strip structure for a tear-off lid of a plastic bucket, including a lid body. A circular groove is opened at the upper end of the lid body. A groove is inwardly opened on the outer side wall of the lid body away from the circular groove. An inclined groove is opened at the upper end of the groove. A limiting hole is opened inside the lid body on the inner side of the groove. A tear-off strip is arranged inside the groove, and the outer side wall of the tear-off strip is flush with the outer side wall of the lid body.

[0007] With the above scheme, the tear-off strip is arranged in the groove opened on the outer side wall of the lid body, and their outer side walls are flush, which not only increases the integrity but also has a certain aesthetic effect. Moreover, both the inclined groove arranged inside the groove and the limiting hole arranged inside the groove can play a role in matching and clamping.

[0008] As a preference of the above technical solution, slot openings are symmetrically opened inside the tear-off strip. A plurality of flexible elastic strips are fixedly connected to the lower end of the slot openings. A dust-proof plate is fixedly connected to the upper end of the flexible elastic strips. An inclined plate is fixedly connected to the upper end of the dust-proof plate. A limiting ball that is clamped with the limiting hole is arranged on the inner side wall of the tear-off strip.

[0009] With the above scheme, the slot openings opened inside the tear-off strip can provide a contraction space for the dust-proof plate and the inclined plate, and complete the contraction function through the flexible elastic strips. After the dust-proof plate pops out, it can effectively increase the surface area of the tear-off strip. The inclined plate can also be in close contact with the lid body through the inclined surface. When it is necessary to close the lid during the intermittent use, both of them can effectively prevent the liquid part in the bucket from being polluted by impurities in the air.

[0010] As a preference of the above technical solution, sliding grooves are symmetrically opened on the inner side wall of the slot openings. Sliding blocks are symmetrically and slidably connected inside the sliding grooves. One of the sliding blocks is connected to the outer side wall of the dust-proof plate. A limiting plate for preventing the sliding block from falling off is arranged on the inner side wall of the sliding groove.

[0011] With the above scheme, the dust-proof plate can be limited by the sliding blocks inside the sliding grooves, so that it will not be loose inside the slot openings, and the limiting plate can prevent the anti-sliding block from falling out of the sliding grooves.

[0012] As a preference of the above technical solution, a fixing strip is arranged on the outer side wall of the tear-off strip. A pull ring is arranged inside the fixing strip. A circular shaft is arranged at the protruding end of the fixing strip, and the circular shaft penetrates through the pull ring, and the pull ring can rotate along the circular shaft.

[0013] With the above scheme, the pull ring can be used to more conveniently tear off the tear-off strip to open the lid body. By arranging a circular shaft inside the fixing strip, the pull ring can rotate along the circular shaft to adjust the clamping angle.

[0014] As a preference of the above technical solution, a fixing plate is arranged on the outer side wall of the tear-off strip on one side of the pull ring. A buckle is arranged on the outer side wall of the fixing plate.

[0015] With the above solution, by setting the fixed plate and the buckle on its outer side wall, it can be matched and snapped with the pull ring, and can provide a certain pulling function when the cover body is reset.

[0016] As a preference of the above technical solution, anti-slip bumps are evenly arranged on the outer side wall of the cover body above the tear strip.

[0017] With the above solution, through the setting of the anti-slip bumps, the friction can be increased, and the convenience of opening the cover body can be improved.

[0018] As a preference of the above technical solution, a clamping strip is arranged on the inner side wall of the cover body, a matching barrel body is arranged below the cover body, and a clamping groove is opened on the outer wall of the upper end of the barrel body.

[0019] With the above solution, through the clamping of the clamping strip in the cover body and the clamping groove in the barrel body, since the plastic has a certain elastic deformation, the clamping can provide a certain tightness for the two. Then, through the clamping of the limiting ball in the tear strip and the limiting hole in the groove of the cover body, the tightness of the two is further improved.

[0020] Compared with the prior art, the beneficial effects of the present utility model are as follows: The cover can be easily opened through the tear strip in the groove of the cover body, and the cover body can be more easily opened through the pull ring. When the tear strip is pulled open, the notch inside it, due to the setting of the flexible elastic strip and the dust-proof plate, and the flexible elastic strip is extruded in the notch during processing, thus generating an inward tightening extrusion force. When the tear strip is fully opened, the flexible elastic strip will release the extrusion force and drive the dust-proof plate to pop out, and drive the inclined plate on the dust-proof plate to pop out together. And because the side wall of the inclined plate is inclined, it can more closely adhere to the side wall of the cover body, so as to prevent dust and dirt in the air from floating into the barrel along with the air and causing pollution. Through the clamping groove arranged on the outer side wall of the barrel body, it can be clamped into the clamping strip arranged on the inner side wall of the cover body when the barrel body and the cover body are combined to improve the tightness, and through the limiting ball arranged on the inner side wall of the tear strip, it can be clamped with the limiting hole on the outer side wall of the cover body, further improving the tightness after the two are reset.

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0028] As Figure 1 shown, the present invention provides a technical solution: a pull strip structure for a pull-open lid of a plastic bucket, including a cover body 1. A circular groove 101 is opened at the upper end of the cover body 1. An inwardly opened groove 102 is provided on the outer side wall of the cover body 1 away from the circular groove 101. An inclined groove 103 is opened at the upper end of the groove 102. A limit hole 104 is opened inside the cover body 1 on the inner side of the groove 102. A pull strip 2 is arranged inside the groove 102. The outer side wall of the pull strip 2 is flush with the outer side wall of the cover body 1. The pull strip 2 is arranged in the groove 102 opened on the outer side wall of the cover body 1, and their outer side walls are flush, which not only increases the integrity but also has a certain aesthetic effect. Moreover, both the inclined groove 103 and the limit hole 104 arranged inside the groove 102 can play a role in matching and clamping.

[0029] As Figure 2 , Figure 3 and Figure 4As shown, symmetrically arranged notches 201 are formed inside the tearing strip 2. A plurality of flexible elastic strips 202 are fixedly connected to the lower bottom end of the notch 201. The upper top end of the flexible elastic strip 202 is fixedly connected to a dust-proof plate 203. The upper top end of the dust-proof plate 203 is fixedly connected to an inclined plate 204. A limiting ball 205 that is engaged with the limiting hole 104 is arranged on the inner side wall of the tearing strip 2. The notch 201 formed inside the tearing strip 2 can provide a contraction space for the dust-proof plate 203 and the inclined plate 204, and the contraction function is completed through the flexible elastic strip 202. After the dust-proof plate 203 pops out, it can effectively increase the surface area of the tearing strip 2. Moreover, the inclined plate 204 can be in close contact with the cover body 1 through the inclined surface. When the cover needs to be closed during the intermittent use, both of them can effectively prevent the liquid part in the barrel body 107 from being contaminated by impurities in the air. Symmetrically arranged sliding grooves 206 are formed on the inner side wall of the notch 201. Symmetrically arranged sliders 207 are slidably connected inside the sliding grooves 206. One of the sliders 207 is connected to the outer side wall of the dust-proof plate 203. A limiting plate 208 for preventing the slider 207 from falling off is arranged on the inner side wall of the sliding groove 206. Through the sliding groove 206, the slider 207 can limit the dust-proof plate 203 so that it will not loosen inside the notch 201, and the limiting plate 208 can prevent the slider 207 from falling out of the sliding groove 206.

[0030] As Figure 4 and Figure 5 shown, a fixing strip 209 is arranged on the outer side wall of the tearing strip 2. A pull ring 210 is arranged inside the fixing strip 209. A round shaft 211 is arranged at the protruding end of the fixing strip 209, and the round shaft 211 penetrates through the pull ring 210, so that the pull ring 210 can rotate along the round shaft 211. Through the pull ring 210, it is more convenient to tear the tearing strip 2 to open the cover body 1. By arranging the round shaft 211 inside the fixing strip 209, the pull ring 210 can rotate along the round shaft 211 to adjust the engaging angle. A fixing plate 212 is arranged on the outer side wall of the tearing strip 2 on one side of the pull ring 210. A buckle 213 is arranged on the outer side wall of the fixing plate 212. By arranging the fixing plate 212 and the buckle 213 on its outer side wall, it can be engaged with the pull ring 210 in a matching manner and can provide a certain pulling function when the cover body 1 is reset.

[0031] As Figure 1 shown, anti-slip convex blocks 105 are evenly arranged on the outer side wall of the cover body 1 above the tearing strip 2. Through the arrangement of the anti-slip convex blocks 105, the friction force can be increased, and the convenience of opening the cover body 1 can be improved. A clamping strip 106 is arranged on the inner side wall of the cover body 1. A matching barrel body 107 is arranged below the cover body 1. A clamping groove 108 is formed on the outer wall of the upper top end of the barrel body 107. Through the clamping of the clamping strip 106 in the cover body 1 and the clamping groove 108 in the barrel body 107, due to the certain elastic deformation of the plastic, the clamping can provide a certain tightness for the two. Further, through the engagement of the limiting ball 205 in the tearing strip 2 and the limiting hole 104 in the groove 102 of the cover body 1, the tightness of the two is further improved.

[0032] Working principle: The operator tears the tearing strip 2 in the groove 102 on the outer side wall of the cover body 1. Since the inclined plate 204 is arranged in the notch 201 of the tearing strip 2, and the staff has snapped the inclined plate 204 into the inclined groove 103 before the cover body 1 leaves the factory. Therefore, when tearing, the extrusion force of the flexible elastic strip 202 in the notch 201 is released, and then drives the dust-proof plate 203 and the inclined plate 204 connected thereto to pop out of the notch 201. Since the popped-up dust-proof plate 203 and inclined plate 204 increase the surface area of the tearing strip 2, it can cover the original position of the tearing strip 2, and the phenomenon of dust and air pollution prevention can be achieved. When it is necessary to close the barrel body 107, the cover body 1 is pressed into the outer surface of the barrel body 107. Since the cover body 1 is provided with a clamping strip 106, and the upper end of the barrel body 107 is provided with a clamping groove 108. Due to the elastic effect of the plastic material, the clamping strip 106 is snapped into the clamping groove 108 to fix the two. The tearing strip 2 is placed back into the groove 102, and the limiting ball 205 arranged on its inner side wall is snapped into the limiting hole 104 arranged on the outer side wall of the cover body 1 for limiting, further improving the tightness of the two and improving the sealing effect to a certain extent.

[0033] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than limiting it.
