Description

Technical Field

[0001] This utility model belongs to the field of chemical storage, specifically a leak-proof storage bottle for low-concentration inorganic acids. Background Technology

[0002] Inorganic acids, as common and widely used corrosive chemical reagents, are extensively applied in chemical reactions, analytical testing, preparation processes, and experimental operations. Inorganic acids are typically highly corrosive and volatile, and they often react with other substances during experiments, sometimes even producing harmful gases. Therefore, effectively preventing leakage, dripping, and reactions with external substances is a crucial issue for experimental safety.

[0003] In experiments using inorganic acids, the sealing of the container and the design of the pouring operation are crucial. While most liquid container caps on the market generally meet the needs of general liquid storage and pouring, their design is not optimized for the corrosive properties of inorganic acids and other liquids, thus having certain shortcomings. During the pouring of inorganic acid liquids, ordinary caps are prone to liquid adhering to the bottle opening or cap surface, leading to dripping. This not only contaminates the bottle but may also cause acid leakage, posing a safety hazard to laboratory personnel. Due to the corrosive nature of inorganic acids, liquid residue and dripping pose significant risks of injury to personnel's skin, clothing, and experimental equipment. Furthermore, the limited sealing performance of ordinary caps allows liquid residue at the bottle opening to react with moisture or impurities in the air, further increasing the danger. Utility Model Content

[0004] The purpose of this invention is to provide a leak-proof storage bottle for low-concentration inorganic acids to solve the problems mentioned in the prior art.

[0005] A leak-proof storage bottle for low-concentration inorganic acids is provided, comprising:

[0006] Bottle body;

[0007] The bottle mouth is provided on the bottle body. The bottle mouth includes an outer convex ring and an inner convex ring. The inner convex ring is sleeved inside the outer convex ring and forms a receiving groove between the inner wall of the outer convex ring and the inner wall of the outer convex ring.

[0008] A bottle cap that can be fitted to the end of the bottle opening furthest from the bottle body.

[0009] Furthermore, taking the direction from the bottle body to the bottle mouth as the vertical direction, the elevation of the top edge of the inner convex ring in the vertical direction is greater than the elevation of the top edge of the outer convex ring in the vertical direction. This structure ensures that when liquid is poured from the bottle, the liquid will flow out along the edge of the inner convex ring, preventing leakage and splashing caused by contact between the liquid and the edge of the outer convex ring.

[0010] Furthermore, the end of the inner rim ring furthest from the bottle body forms a flared opening with an increasing diameter along the direction of departure. When pouring, the outer wall of the flared opening has a larger angle with the direction of flow discharge relative to the cylindrical outer wall, making it less likely for liquid to adhere to the edge and outer wall of the flared opening.

[0011] Furthermore, the flared portion is recessed towards the central axis of the bottle opening. This recess creates an arc-shaped guiding structure on the inner wall surface, allowing the liquid to flow back into the bottle through the inward angle of the inner wall after pouring, reducing liquid adhesion. This structure utilizes the surface tension of the liquid to guide its return into the bottle while preventing spillage along the outer side of the bottle opening.

[0012] Furthermore, after the bottle cap is fitted with the bottle opening, the top edge of the inner convex ring fits against the inner top wall of the bottle cap. After the bottle cap is placed on the bottle opening, the bottom wall of the bottle cap will press against the top of the inner convex ring, causing the inner convex ring to deform to a certain extent, thereby forming a sealing structure between the bottle cap and the inner convex ring, enhancing the sealing performance of the bottle opening.

[0013] Furthermore, the end of the outer convex ring furthest from the bottle body extends away from the central axis of the bottle opening to form an anti-overflow ring. After the bottle cap is fitted with the bottle opening, the anti-overflow ring fits against the inner side wall of the bottle cap. When the bottle cap is placed on the bottle opening, the side wall of the bottle cap compresses the anti-overflow ring of the outer convex ring, causing a certain degree of deformation. This forms a sealing structure between the bottle cap and the outer convex ring, enhancing the sealing performance of the bottle opening. In addition, the compression between the bottle cap and the anti-overflow ring increases the friction between them, thereby strengthening the fit between the bottle cap and the bottle opening and improving the tightness of the fit.

[0014] Furthermore, the bottle neck and bottle body are detachably connected. Removing the bottle neck entirely from the bottle body facilitates liquid filling and prevents dripping and splashing when filling from the inner edge ring. The detached bottle neck also results in a larger opening diameter, leading to more efficient liquid filling.

[0015] Furthermore, a hinge is provided between the bottle cap and the bottle opening. The hinge facilitates opening and closing the bottle cap and prevents it from being lost.

[0016] Furthermore, the inner wall of the inner edge protruding ring is provided with at least one opening extending at an angle of α degrees, where the angle α is 60° to 120°. The opening with a certain angle allows for the formation of a more concentrated flow stream when liquid is poured out, optimizing the flow rate and volume control during the liquid pouring process, reducing the surging effect during liquid pouring, making the liquid flow more stable, and less prone to overflow or dripping.

[0017] Furthermore, a plunger that mates with the opening is disposed inside the inner convex ring, and a pull ring is provided at the end of the plunger away from the bottle body. The engagement of the plunger with the opening further enhances the sealing performance of the bottle mouth. When the storage bottle is sealed, the plunger can be inserted into the bottle mouth to effectively prevent acid leakage or dripping. When it is necessary to pour the liquid, the plunger can be easily removed by pulling the pull ring, ensuring simple operation. This design not only improves the sealing effect of the bottle mouth but also facilitates operation by laboratory personnel, ensuring the safe storage and use of low-concentration inorganic acids and avoiding potential hazards to the experimental environment and personnel from acid leakage.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] When the liquid inside the bottle is poured out from the bottle opening, the inner rim ring acts as a guide to guide the liquid out. If there is liquid residue on the edge of the inner rim ring, the residual liquid will slide down the outer wall of the inner rim ring into the receiving groove between the inner and outer rim rings. This effectively prevents acid from leaking into the bottle during use, ensuring that no liquid will splash or drip during pouring, and providing a safer and more efficient experimental operating environment.

[0028] However, there may be instances where unnecessary detailed descriptions are omitted. For example, detailed descriptions of well-known matters or repetitive descriptions of essentially the same structures may be omitted. This is to avoid unnecessarily lengthy descriptions and to facilitate understanding by those skilled in the art. Furthermore, the accompanying drawings and the following description are provided to enable those skilled in the art to fully understand this application and are not intended to limit the subject matter of the claims.

[0029] Please see Figure 1-2 As shown in the embodiment of this utility model, a leak-proof storage bottle for low-concentration inorganic acids includes a bottle body 1, a bottle mouth 2, and a bottle cap 3. The bottle mouth 2 is disposed on the bottle body 1 and includes an outer convex ring 21 and an inner convex ring 22. The inner convex ring 22 is fitted inside the outer convex ring 21 and forms a receiving groove 23 between the inner convex ring 21 and its inner wall. The bottle cap 3 can cooperate with the end of the bottle mouth 2 away from the bottle body 1.

[0030] An outer convex ring 21 is mounted on the bottle body 1. One end of an inner convex ring 22 is integrally formed with the inner wall of the outer convex ring 21 and spaced a certain distance apart, forming a receiving groove 23. The inner convex ring 22 is a through structure that connects the inside of the bottle body 1 to the outside. When pouring liquid, the inner convex ring 22 acts as a guide, ensuring smooth liquid flow. When liquid remains on the edge of the inner convex ring 22, this residual liquid will slide down the outer wall of the inner convex ring 22 into the receiving groove 23, preventing liquid from dripping onto the outside of the bottle body 1 or splashing out. This design effectively prevents acid leakage, improves the safety of experimental operations, and enhances the cleanliness of the experimental environment. After the liquid has been poured out, the bottle cap 3 is fitted with the bottle mouth 2 to complete the seal.

[0031] The bottle body 1, bottle mouth and bottle cap 3 are made of polytetrafluoroethylene. As a storage bottle for inorganic acids, it ensures that the structure will not fail due to corrosion of inorganic acids during long-term storage.

[0032] With the direction from bottle body 1 to bottle mouth 2 as the vertical direction, the elevation of the top edge of the inner convex ring 22 in the vertical direction is greater than the elevation of the top edge of the outer convex ring 21 in the vertical direction. This design allows liquid to flow smoothly from the edge of the inner convex ring 22 when poured, and avoids dripping and splashing caused by liquid contact with the outer convex ring 21. The elevation design of the top of the inner convex ring 22 ensures that when liquid flows out through the inner wall, it will not overflow along the edge of the outer convex ring 21, thereby enhancing the liquid guiding effect and sealing performance of the bottle mouth 2 and reducing the risk of liquid residue in the bottle mouth 2.

[0033] Please see Figures 1-3 As shown, the end of the inner rim ring 22 furthest from the bottle body 1 forms a flared opening 221 with an increasing diameter along the direction of distance. The design of the flared opening 221 allows the liquid to flow out more smoothly when poured. Through the angled design of the outer wall of the flared opening 221, the liquid is less likely to adhere to the edge or outer wall of the flared opening 221, further reducing the problems of liquid residue and leakage.

[0034] When the bottle cap 3 is fitted with the bottle mouth 2, the top edge of the inner convex ring 22 fits against the top inner wall of the bottle cap 3. The design of the flared part 221 allows the edge of the flared part 221 to undergo a certain degree of uniform deformation along the expansion direction without creating gaps when the bottle cap 3 squeezes the inner convex ring 22, thereby enhancing the sealing performance between the bottle cap 3 and the inner convex ring 22.

[0035] Furthermore, the flared portion 221 is recessed towards the central axis of the bottle mouth 2, forming an arc-shaped trumpet structure. This arc-shaped guiding structure of the flared portion 221 effectively utilizes the surface tension of the liquid to allow it to flow smoothly back into the bottle after being poured out. This structure reduces liquid adhesion to the flared portion 221, preventing liquid from overflowing between the cap 3 and the flared portion 221 when the cap 3 is squeezed.

[0036] The outer edge protruding ring 21 extends from the end away from the bottle body 1 in a direction away from the central axis of the bottle mouth 2 to form an anti-overflow ring 211. The anti-overflow ring 211 can be an outwardly protruding annular structure or a flared structure with a diameter that gradually increases. After the bottle cap 3 is engaged with the outer edge protruding ring 21, the anti-overflow ring 211 will undergo a certain degree of deformation, thereby forming a tight-contact sealing structure, effectively preventing liquid leakage or external air from entering the bottle.

[0037] The bottle neck 2 and bottle body 1 are detachably connected, specifically via a threaded connection. This detachable connection facilitates liquid filling and cleaning of bottle body 1. By removing the bottle neck 2, operators can more easily add liquid and clean bottle body 1, avoiding dripping or splashing issues when filling liquid using the bottle neck 2. Furthermore, removing the bottle neck 2 results in a larger opening diameter for bottle body 1, improving liquid filling efficiency and reducing operational complexity.

[0038] A hinge 4 is provided between the bottle cap 3 and the bottle mouth 2. The design of the hinge 4 makes opening and closing the bottle cap 3 easier and less likely to be lost. Through the hinge 4, the bottle cap 3 is always connected to the bottle mouth 2, avoiding the risk of the bottle cap 3 being lost or falling off. The hinge 4 can be a rotatable hinge structure or a deformable elastic element.

[0039] Please see Figure 2 and Figure 4 As shown, the inner wall of the inner edge protruding ring 22 is provided with at least one opening 222 extending at an angle of α degrees, where the angle α is 60° to 120°. Specifically, the opening 222 can be a rhomboid structure, allowing the bottle opening 2 to have multiple pouring directions. This design effectively concentrates the liquid flow direction, optimizing the flow rate and flow control during liquid pouring. This design helps reduce the gushing effect during liquid pouring, making the liquid flow more stable and reducing the risk of spillage or dripping. In addition, the angle setting allows the liquid to flow more concentratedly in the designated direction, preventing the liquid from being dispersed at the edge of the bottle opening 2 and ensuring the controllability of the liquid flow.

[0040] The inner rim ring 22 houses a plunger 51 that mates with the opening 222. A pull ring 52 is located at the end of the plunger 51 furthest from the bottle body 1. When the plunger 51 is inserted into the opening 222 of the inner rim ring 22, a fully sealed structure is formed to prevent acid leakage. The pull ring 52 at the end of the plunger 51 furthest from the bottle body 1 allows for easy removal of the plunger 51, enabling easy dispensing of the liquid when needed. This design not only improves the sealing effect of the bottle opening 2 but also simplifies the operation for laboratory personnel, ensuring the safety of the acid during storage and use.

[0041] It should be noted that this application is not limited to the above-described embodiments. The above embodiments are merely examples, and any embodiments with the same structure and effect as the technical concept within the scope of this application are included in the technical scope of this application. Furthermore, various modifications that can be conceived by those skilled in the art to the embodiments, and other ways of constructing by combining some of the constituent elements of the embodiments, without departing from the spirit of this application, are also included in the scope of this application.
