Description

Technical Field

[0001] This utility model relates to the field of cleaning products technology, specifically to an integrated sealing device for cleaning liquid bottles. Background Technology

[0002] Bottled cleaning liquids (such as hand sanitizer and detergent) are commonly found in homes, public restrooms, and kitchens. These liquids are typically dispensed via bottles attached to cleaning pumps or machines. Once the liquid is used up, the bottle needs to be replaced. Before use, the bottle opening must be sealed to prevent leakage; therefore, a sealing device is required at the bottle opening. Traditional sealing devices are often cap seals, achieved through a threaded connection between the cap and the bottle opening. However, these bottles require manual unscrewing of the cap for use, making installation and replacement somewhat cumbersome.

[0003] To improve ease of use, a liquid bottle sealing device has emerged on the market that allows for direct opening of the bottle neck by simply inserting it into a cleaning pump head or machine, such as... Figure 1-2 As shown. When this type of liquid bottle is not in use, the spring 4 is open, causing the liquid outlet 301 on the sealing plug 3 to be misaligned with the cavity inside the bottle body 1. The sealing ring 5 and the bottle cap 2 seal against each other, preventing the liquid inside the bottle from leaking. During installation, the sealing plug 3 is aligned with the cleaning pump or machine. The cleaning pump or machine will push the sealing plug 3 into the bottle body 1, compressing the spring 4 until the liquid outlet 301 on the sealing plug 3 is connected to the cavity inside the bottle. At this time, the cleaning liquid inside the bottle can flow out of the bottle opening through the misaligned hole.

[0004] However, existing bottle-mouth sealing devices of this type still have the following problems:

[0005] 1. Additional accessories such as springs and sealing rings are required, making assembly complex and costly.

[0006] 2. Springs are mostly made of metal, while the bottle body and sealing plug are mostly made of plastic. They need to be disassembled for recycling after use, which increases the difficulty and cost of recycling. Utility Model Content

[0007] To address some or all of the problems existing in the prior art, this utility model provides an integrated sealing device for cleaning liquid bottles, comprising a bottle body with a liquid storage chamber for holding cleaning liquid. One end of the bottle body is a liquid outlet, and a bottle cap is provided on the liquid outlet. A sealing plug is provided inside the bottle cap. The sealing plug is an integrally formed structure, including a central column. A limiting ring is provided on the outer wall of the central column, and a flow guide groove is provided inside the central column. One end of the central column has a symmetrical elastic arm, and one end of the elastic arm abuts against the bottle cap. In its natural state, the elastic arm is open, and the limiting ring and the bottle cap are in sealing contact. After the elastic arm is deformed under pressure, the flow guide groove can communicate with the liquid storage chamber.

[0008] As a further improvement of this utility model, the elastic arm is in the shape of a frustum.

[0009] As a further improvement of this utility model, the thickness of the end where the elastic arm connects to the central column is greater than the thickness of the other end.

[0010] As a further improvement of this utility model, the bottle cap is provided with an installation hole, the installation hole is provided with a limiting step, the sealing plug passes through the installation hole, and the end of the elastic arm away from the central column abuts against the limiting step.

[0011] As a further improvement of this utility model, the liquid outlet end of the bottle body is provided with an external thread, and the bottle cap is provided with an internal thread adapted to the external thread, and the bottle cap is threadedly connected to the bottle body.

[0012] As a further improvement of this utility model, the outer side wall of the bottle cap is provided with an array of anti-slip ridges.

[0013] As a further improvement of this utility model, the sealing plug is made of elastic silicone material.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This utility model features an integrated sealing plug design, reducing the number of parts, assembly difficulty, and manufacturing costs. Furthermore, it eliminates the need for a metal spring, allowing for direct recycling after use without disassembly, thus reducing recycling difficulty and costs and meeting environmental protection requirements. Normally, the cleaning fluid is contained within the storage chamber. The elastic arm opens, allowing the limiting ring to seal against the bottle cap, preventing leakage of the cleaning fluid. During use, aligning the bottle cap with the cleaning pump or machine causes the pump or machine to compress the sealing plug, pushing the central column into the storage chamber. The central column compresses the elastic arm, causing it to deform elastically until the guide groove connects with the storage chamber. At this point, the cleaning fluid in the storage chamber can flow out through the guide groove, facilitating user access. Attached Figure Description

[0022] Unless otherwise defined, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used in the specification is for the purpose of describing particular embodiments only and is not intended to limit the invention; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and accompanying drawings of this invention are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or accompanying drawings of this invention are used to distinguish different objects, not to describe a particular order.

[0023] In this invention, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this invention. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment to other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this invention can be combined with other embodiments.

[0024] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0025] like Figure 3-5 As shown, a cleaning liquid bottle includes a bottle body 1, with a storage chamber 11 for holding the cleaning liquid inside the bottle body 1. One end of the bottle body 1 is a liquid outlet 12, and a bottle cap 2 is installed on the liquid outlet 12. A sealing plug 3 is provided inside the bottle cap 2. The bottle cap 2 is used to install the sealing plug 3, and the sealing plug 3 is used to open or close the liquid outlet 12.

[0026] For ease of assembly, an external thread 13 is provided on the liquid outlet 12, and an internal thread 21 adapted to the external thread 13 is provided on the bottle cap 2. The bottle cap 2 is threadedly connected to the bottle body 1. The bottle cap 2 can be easily installed onto the bottle body 1 by aligning the internal thread 21 on the bottle cap 2 with the external thread 13 on the bottle body 1. In other embodiments, the bottle cap 2 and the bottle body 1 can also adopt other connection methods, such as snap-fit ​​or adhesive bonding.

[0027] In this embodiment, to facilitate operation, anti-slip ridges 22 are arrayed on the outer side wall of the bottle cap 2. By providing the anti-slip ridges 22, the friction between the bottle cap 2 and the operator's hand is increased, thereby preventing hand slippage during installation and improving installation efficiency. In other embodiments, other types of anti-slip structures can also be provided on the outer side wall of the bottle cap 2, such as anti-slip grooves, anti-slip bumps, etc.

[0028] The sealing plug 3 adopts an integrated molding structure and can be made of elastic silicone or other elastic materials. The sealing plug 3 includes a central post 31, a limiting ring 32 on the outer wall of the central post 31, a flow guide hole 33 inside the central post 31 extending to the upper end face of the central post 31, and a symmetrical elastic arm 34 at one end of the central post 31. The bottle cap 2 has a mounting hole 23, and a limiting step 24 inside the mounting hole 23. When installing the sealing plug 3, the central post 31 is passed through the mounting hole 23, and the limiting ring 32 on the central post 31 also passes through the mounting hole 23. During this process, the elastic arm 34 abuts against the limiting step 24 and is deformed by the limiting step 24. After the limiting ring 32 passes through the mounting hole 23, the central post 31 is released, and the elastic arm 34 automatically returns to its original position under the action of elasticity, so that the limiting ring 32 and the bottle cap 2 are sealed together.

[0029] Therefore, after the sealing plug 3 is installed, in its natural state, the end of the elastic arm 34 away from the central column 31 abuts against the limiting step 24, causing the limiting ring 32 to seal against the bottle cap 2. This seals the outlet end 12 of the bottle body 1, preventing the cleaning liquid in the storage chamber 11 from flowing out. When this cleaning liquid bottle is installed on a cleaning pump or machine, the bottle cap 2 can be aligned with the pump or machine, and the pump or machine can push the sealing plug 3 towards the storage chamber 11. During the movement of the sealing plug 3, the central column 31 will squeeze the elastic arm 34, causing it to deform elastically until the guide groove 33 connects with the storage chamber 11. At this point, the cleaning liquid in the storage chamber 11 can flow out through the guide groove 33, making it convenient for the user.

[0030] The sealing plug 3 in this cleaning liquid bottle adopts an integrated structural design, which reduces the number of parts, lowers the difficulty of assembly, and also reduces the manufacturing cost. On the other hand, there is no need to install a metal spring, and it can be directly recycled as a whole after use without disassembly, which reduces the difficulty and cost of recycling and meets environmental protection requirements.

[0031] In this embodiment, the elastic arm 34 is in the shape of a frustum. In other embodiments, the elastic arm 34 may also be in other symmetrical shapes, as long as it can achieve elastic deformation and recovery.

[0032] The thickness of the end connecting the elastic arm 34 and the central column 31 is greater than the thickness of the other end. This design makes the elastic arm 34 more likely to deform under pressure. On the other hand, it can also reduce the risk of breakage at the connection between the elastic arm 34 and the central column 31 under pressure, thus extending the service life.

[0033] The above-described specific embodiments are preferred embodiments of this utility model, and are not intended to limit the specific scope of this utility model. The scope of this utility model includes but is not limited to the specific embodiments described above. All equivalent changes made in accordance with this utility model are within the protection scope of this utility model.
