Description

Technical Field

[0001] The utility model relates to the technical field of daily necessities containers, in particular to a rotary sealing cover for a cleaning liquid bottle. Background Art

[0002] The rotary sealing cover is a common sealing technology, which is usually used on the lid or cover of containers or equipment to ensure that the liquid in the container will not leak or be contaminated by the outside world. This type of sealing cover covers many fields such as food and beverage packaging, chemical containers, and pharmaceutical bottles.

[0003] After searching, the Chinese patent "A Rotary Sealing Bottle Structure" with the authorization announcement number "CN 213503309U" adopts a sealing method that uses a threaded connection and a sealing plug. The bottle cap is spirally connected to the outer wall of the bottle body, so that the bottle cap tightly presses the sealing plug 2, and the sealing plug 2 is tightly pressed in the top annular groove 3 of the sealing cover; the sealing cover is spirally connected to the inner wall of the bottle body, so that the edge of the cover tightly presses the sealing plug 1, and the sealing plug 1 is tightly pressed in the annular groove 1 on the top wall of the bottle mouth, forming a multiple sealing structure with good sealing performance. Since the spiral connection position between the bottle cap and the bottle body, and the sealing cover and the bottle body is fixed, the interference is constant during the cooperation, so that the interaction between the bottle cap and the sealing cover, and the sealing cover and the bottle body is constant, making the sealing structure stable and the service life increased.

[0004] Although the patented technology solves the problem that the sealed bottle packaging has poor quality preservation, fragrance preservation and moisture retention of the product after the sealing structure is destroyed, especially the shelf life of the sealed bottle is reduced to the lowest after opening, and it can hardly play the role of sealing and preserving the product, and the secondary sealed bottle packaging with good performance, its sealing equipment is mostly complex in structure, or requires manual adjustment by humans during packaging, and more man-hours are spent on each sealed bottle packaging, which not only reduces production efficiency but also increases production costs. However, the patented technology connects the sealing cap to the bottle body by a threaded connection. In actual use, when pouring the liquid in the bottle body, the liquid often flows along the bottle mouth to the threaded connection, and there are usually tiny gaps between the inner and outer surfaces of the thread to allow them to nest and rotate with each other to play a role of mechanical connection, which causes the liquid to leak through these tiny gaps. Therefore, a rotary sealing cap for a cleaning liquid bottle is proposed to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a rotary sealing cap for a cleaning liquid bottle in order to solve the above-mentioned problem, which improves the problem that when pouring the liquid in the bottle, the liquid tends to flow along the bottle mouth to the threaded connection, and there are usually tiny gaps between the inner and outer surfaces of the threads, so that they can be nested and rotated with each other to play a role of mechanical connection, which makes the liquid leak through these tiny gaps.

[0006] The utility model achieves the above-mentioned purpose through the following technical scheme, a rotary sealing cover for a cleaning liquid bottle, comprising an inner cover body; a reflux component, the reflux component comprising a pouring plate fixedly connected to the top of the inner cover body, the top of the inner cover body is located on the outside of the pouring plate and is provided with an inclined guide groove, and the inner surface of the inner cover body is located on one side of the inclined guide groove and is provided with a reflux opening.

[0007] Preferably, the reflux opening and the pouring plate are axially symmetrically distributed relative to the axis of the inner cover body, the liquid pouring position and the reflux position are symmetrical to each other, and the height of the pouring plate is relatively high, so that the user will not confuse the pouring plate with the reflux opening.

[0008] Preferably, the height of the inclined guide groove gradually decreases from the pouring plate to the reflux opening, so that the liquid flowing into the inclined guide groove can flow to the reflux opening through the height difference of the inclined guide groove and flow back into the bottle body through the reflux opening.

[0009] Preferably, the outer surface of the inner cover body is threadedly connected to the outer cover body, and the inner top of the outer cover body is fixedly connected to a circular sealing ring. After the outer cover body is connected to the inner cover body, the circular sealing ring will enter the inner cover body and fit tightly against the inner surface of the inner cover body and cooperate with the rubber scraper below to prevent the liquid in the bottle from leaking when the outer cover body is connected to the inner cover body.

[0010] Preferably, the outer diameter of the circular sealing ring is consistent with the inner diameter of the inner cover body, so that the circular sealing ring will not be scratched with the tipping plate on the top of the inner cover body when entering the inner cover body, so as to prevent the circular sealing ring from colliding with the tipping plate and causing damage when the outer cover body is twisted.

[0011] Preferably, a connecting column is fixedly connected to the inner top of the outer cover body. The rubber scraper will generate friction resistance when it contacts the inner cover body. The connecting column fixes the rubber scraper to prevent the rubber scraper from deviating due to friction resistance when it contacts the inner cover body.

[0012] Preferably, a rubber scraper is fixedly connected to the bottom of the connecting column, which can scrape off the cleaning liquid remaining on the inner surface of the inner cover to prevent the cleaning liquid from solidifying at the bottle mouth. At the same time, after the bottle loses its vacuum sealing state when the outer cover is unsealed, the rubber scraper can also play a sealing role. When the cleaning liquid bottle falls over, the rubber scraper will block the cleaning liquid in the cleaning liquid bottle to prevent the cleaning liquid from leaking.

[0013] Preferably, the outer diameter of the rubber scraper is consistent with the inner diameter of the inner cover body, so that the rubber scraper will not scratch the pouring plate on the top of the inner cover body. At the same time, when the rubber scraper moves inside the inner cover body, it will not touch the reflux opening, and after the liquid in the reflux opening is refluxed, the rubber scraper will scrape off the residual liquid on the surface of the inner cover body.

[0014] The beneficial effects of the utility model are:

[0015] 1. After the cleaning liquid is poured out, some liquid will remain on the surface of the pouring plate. These liquids will flow to the inner and outer sides of the pouring plate. The liquid flowing to the outer side will flow into the reflux opening through the action of the inclined guide groove, and flow back into the bottle body together with the liquid flowing to the inner side of the pouring plate. This solves the problem that when pouring the liquid in the bottle body, these liquids tend to flow along the bottle mouth to the threaded connection, and there are usually tiny gaps between the inner and outer surfaces of the thread, which causes the liquid to leak through these tiny gaps;

[0016] 2. When the outer cover moves downward, the rubber scraper under the connecting column will move downward along the inner diameter of the inner cover to scrape off the cleaning liquid remaining on the inner surface of the inner cover. The scraped cleaning liquid will drip into the cleaning liquid bottle to prevent the cleaning liquid from solidifying at the bottle mouth. BRIEF DESCRIPTION OF THE DRAWINGS

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] When implementing: Figure 1-5 As shown, a rotary sealing cover for a cleaning liquid bottle includes an inner cover body 1; a reflux assembly 2, the reflux assembly 2 includes a pouring plate 21 fixedly connected to the top of the inner cover body 1, an inclined guide groove 22 is provided on the top of the inner cover body 1, and a reflux opening 23 is provided on the inner surface of the inner cover body 1, which is located on one side of the inclined guide groove 22.

[0025] like Figure 3 , Figure 4 and Figure 5 As shown, the reflux opening 23 and the pouring plate 21 are axially symmetrically distributed relative to the axis of the inner cover body 1, and the height of the inclined guide groove 22 gradually decreases from the pouring plate 21 to the position of the reflux opening 23, so that the liquid flowing into the inclined guide groove 22 can flow to the position of the reflux opening 23 by gravity, and flow back into the bottle body through the reflux opening 23.

[0026] like Figure 1 , Figure 2 and Figure 4 When the bottle cap 1 is in the closed position, the sealing ring 31 is fixed on the top of the inner side of the bottle cap 1 and the outer side of the bottle cap 1 is in the closed position, so that the outer sealing ring 31 is fixed on the inner side of the bottle cap 1 and the outer side of the bottle cap 1 is in the closed position, so that the outer sealing ring 31 is fixed on the top of the inner side of the bottle cap 1 and the outer side of the bottle cap 1 is in the closed position, so that the outer sealing ring 31 is fixed on the inner side of the bottle cap 1 and the outer side of the bottle cap 1 is in the closed position, so that the outer sealing ring 31 is fixed on the top of the inner side of the bottle cap 1 and the outer side of the bottle cap 1 is in the closed position, so that the outer sealing ring 31 is fixed on the

[0027] When the user needs to pour the cleaning liquid, the outer cover 3 is opened and the cleaning liquid is poured toward the position of the pouring plate 21. The cleaning liquid will flow out through the pouring plate 21. When the pouring is completed, part of the liquid will remain on the surface of the pouring plate 21. These liquids will flow to the inner and outer sides of the pouring plate 21. The liquid flowing to the outside will flow into the reflux opening 23 through the action of the inclined guide groove 22, and flow back into the bottle body together with the liquid flowing to the inner side of the pouring plate 21. After that, the outer cover 3 is tightened. At this time, the rubber scraper 5 under the connecting column 4 will move downward along the inner diameter of the inner cover 1 to scrape off the cleaning liquid remaining on the inner surface of the inner cover 1 and the inner surface of the pouring plate 21. The scraped cleaning liquid will drip into the bottle body. When the outer cover 3 is fixed, the rubber scraper 5 is at the connection between the inner cover 1 and the bottle body, so that the bottle body can obtain a good sealing.

[0028] It should be noted that the tipping plate 21, circular sealing ring 31 and rubber scraper 5 in the above description are all relatively mature devices in the existing technology. The specific models can be selected according to actual needs and will not be described in detail here.
