Description

Technical Field

[0001] This utility model relates to the field of tile grout, and more particularly to a sealing device for the nozzle part of a polyurea tile grout bottle. Background Technology

[0002] The opening features a closed design; to ensure that the bottle opening does not come into contact with air, the nozzle has been improved from an open structure to a completely sealed one, as detailed below. Figure 8 As shown.

[0003] Existing technology involves sealing the bottle opening, which effectively prevents air from entering and avoids oxidation and contamination. However, because the bottle opening is completely sealed, filling cannot be done from the opening; only a tail-filling method can be used (hereinafter referred to as "rear-filling"). While this rear-filling method achieves filling, the extremely small space at the bottle opening and the high viscosity of the polyurea grout components prevent air from escaping smoothly during filling, making it difficult to eliminate residual air bubbles. Over time, and due to bumps and vibrations during transportation, these air bubbles move and accumulate within the bottle, further promoting contact between the active components in the polyurea grout and the residual air, thus accelerating the curing reaction and affecting the product's stability and lifespan. Details are as follows... Figure 7 As shown.

It should be understood that the following specific embodiments are only for illustrating the present invention and are not intended to limit the scope of the present invention.

[0021] This patent provides multiple parallel solutions; the different descriptions represent improved or parallel solutions based on a basic solution. Each solution has its own unique characteristics. Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other. Fixing methods not described herein can be any type of fixing, such as threaded fixing, bolt fixing, or adhesive bonding.

[0022] Example 1: Referring to all the attached drawings; the sealing device at the nozzle of the polyurea grout bottle, with two cylindrical bodies 4 connected to one opening, and a partition plate 3 arranged at the opening, characterized in that: The sealing device includes a plug 5 that can plug the opening 2; the plug 5 includes a top cover 51, the top cover 51 is connected to two solid halves 52 by an upper mating structure 55, and a gap 53 is arranged between the two solid halves 52. The two solid halves 52 can be inserted into both sides of the partition 3; a closed structure 54 is arranged above the two solid halves 52; the closed structure 54 can achieve airtightness; The length of the solid half-body 52 is equal to the length of the opening. The substantial technical effect and its implementation process, i.e., the basic function and non-obviousness, are as follows: [Comparison] Figure 8 And the remaining attached figures; the main problem this utility model solves is: the nozzle part of the polyurea grout bottle, preventing the active components of the polyurea grout from curing upon contact with air before use.

[0023] The original sealed bottle opening was replaced with an open one; and the nut was modified by adding a layer of soft sealing material such as silicone or rubber to the plug inside the nut, which not only sealed the bottle opening but also blocked the bottleneck area, thus solving the problem of incomplete filling at the bottleneck area.

[0024] This invention combines the principle of a rubber stopper, which not only isolates external air but also prevents air residue by blocking the bottle neck. This essentially solves the problem of polyurea grout products reacting with air at the bottle opening. Details of the air reaction at the bottle opening are as follows... Figure 7 As shown.

[0025] The sealing plug is made to the same height as the bottle neck, and the bottle neck is sealed with the plug. This will prevent problems such as incomplete filling and air residue during subsequent filling.

[0026] By adding a sealing device to the bottle neck nut, both the entry of external air and the air residue caused by incomplete filling are prevented; overall, the problem of air solidification at the head of the seamless polyurea bottle series has been overcome.

[0027] Example 2: As a further improvement, parallel solution, or optional independent solution, the solid half 52 is made of silicone or rubber. The substantial technical effect and its implementation process, i.e., the basic function and non-obviousness, are as follows: similar materials are all within the scope of protection of this patent.

[0028] Example 3: As a further improvement, parallel, or optional independent solution, gap 53 can clamp the separator 3. The substantial technical effect and its implementation process, i.e., the basic function and non-obviousness, are as follows: achieving tight sealing and airtightness.

[0029] Example 4: As a further improvement, parallel, or optional independent solution, the closed structure 54 includes multiple rings of protrusions, with a smaller lower diameter and a larger upper diameter. The substantial technical effect and its implementation process, i.e., the basic function and non-obvious aspects, are as follows: better sealing effect.

[0030] Example 5: As a further improvement, parallel, or alternative independent solution, the two solid halves 52 are arranged symmetrically. The substantial technical effect and its implementation process, i.e., the basic function and non-obviousness, are as follows: thus, a seal can be achieved equivalently.

[0031] Example 6: As a further possible improvement, parallel solution, or optional independent solution, the overall structure of the plug 5 is an integrated structure.

[0032] Innovatively, each of the above effects exists independently, yet a single structure can be used to combine the results.

[0033] It should be noted that the multiple solutions provided in this patent include their own basic solutions, which are independent of each other and do not restrict each other. However, they can also be combined with each other without conflict to achieve multiple effects.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
