Description

Technical Field

[0001] The present invention relates to the field of packaging of functional solvent materials, specifically to the field of packaging of a primer, and particularly to a convenient liquid primer packaging. Background Art

[0002] A primer, also known as a primer treatment agent or a primer-type adhesion treatment agent, can be applied to the surface of a substrate by spraying or brushing. It can wet the substrate and at the same time assist in enhancing the adhesion between the substrate and paint or glue, improving the reliability. Common primers include: nylon primer, PP and PVC primers, metal primers, etc.

[0003] If the functions of the primer are distinguished according to different surface treatment processes, in the adhesive process, it mainly improves the bonding strength between the adhesive and the substrate, solves problems such as degumming of difficult-to-bond substrates, has good wettability and adhesion ability, and promotes the combination of the two through the connection channels of the primer. Moreover, in the spray painting process, it promotes the adhesion of the paint to the substrate by improving the surface of the substrate and enhancing the interlayer adhesion, achieving a firm coating.

[0004] Currently, the packaging of primers is in the shape of "cans" or "bottles" made of metal, which are relatively large. The usage method is to dip a brush into the primer substance and brush it on the surface of the substrate. This packaging method and usage method are suitable for large-scale industrial use, but are very inconvenient for small-scale use in the DIY industry, and there is a risk of polluting other surrounding substrates and causing great waste.

[0005] At the same time, due to the corrosiveness of the primer, when using ordinary packaging materials, it is easy to corrode the packaging materials; at the same time, the primer is easy to absorb the components in the packaging materials and swell, resulting in the packaging becoming brittle, deformed, and weakened in strength; in addition, there are also easy airtightness problems. Due to poor airtightness, over time, the primer in the packaging decreases.

[0006] In view of the above problems, there is an urgent need to innovate and design a more convenient and fast packaging dedicated to primers that can be used in the DIY industry. Summary of the Invention

[0007] In order to solve the above problems and make the primer better adapted to the DIY industry, the present invention proposes a new convenient liquid primer packaging. This packaging has the characteristics of being convenient to carry, easy to use, saving primer, and not polluting the surrounding substrates; it is very suitable for the DIY industry.

[0008] The present invention provides a liquid primer package, characterized in that it includes a container body and an opening and closing mechanism, wherein the container body and the opening and closing mechanism can be airtightly combined into one, and the opening and closing mechanism is installed at the top end of the container body; the container body is used to fill the primer inside, and has an outlet at the top end for guiding the primer outward; the opening and closing mechanism can selectively switch between a closed state that closes the connection between the primer filling space of the container body and the outside and an open state that can guide the primer outward.

[0009] The primer is also called a primer treatment agent or a primer-type adhesion treatment agent, which can be applied to the surface of the substrate by spraying or brushing, can wet the substrate, and at the same time help enhance the adhesion between the substrate and the paint or glue, thereby improving reliability.

[0010] Furthermore, the primer is a nylon primer, a PP primer or a metal primer.

[0011] Furthermore, the primer refers to a metal primer, and its main components include ethyl acetate, butyl acetate, etc.

[0012] Furthermore, the opening and closing mechanism includes a plug, which is composed of a shell, a latch and a spring. The shell and the latch are made of any one of polystyrene, ABS plastic, polyvinyl chloride, polyester, polyamide or polyethylene.

[0013] The shell and the latch are made of any one of polystyrene, ABS plastic, polyvinyl chloride, polyester, polyamide or polyethylene. These materials have the following characteristics: 1. Good compatibility with the primer, not corroded or dissolved, and will not affect the performance of the primer; 2. Excellent engineering mechanics, can form a very good match with the main body of the primer container to ensure that the primer will not leak out; 3. The primer will not swell due to absorbing the components in the packaging material.

[0014] Furthermore, the shell and the latch are made of any one of polyvinyl chloride, polyester, polyamide or polyethylene.

[0015] Furthermore, the housing and the latch are both made of polyethylene.

[0016] Furthermore, the shell has an open channel, and the latch has a snap ring, which can completely cover the channel.

[0017] Furthermore, the latch includes a front end, a snap ring and a tail, the snap ring is located between the front end and the tail, and the front end is covered with a spring; when an external force acts on the tail of the latch, the latch moves inward, the spring is compressed, the snap ring leaves the channel, and the channel opens; when the external force is removed, the spring rebounds, the latch resets, the snap ring completely covers the channel, and the channel closes.

[0018] Further, the outer shell includes a shell body and a shell cover. The shell cover is a hollow structure with a frustum that mates with the upper part of the shell body. The outer wall of the frustum is provided with an annular protrusion, which can be closely fitted with the shell body.

[0019] Further, the through hole is located at the center of the top of the frustum, and the tail of the plug can pass through the through hole and extend out of the shell cover from the frustum.

[0020] Further, the through hole is located at the center of the frustum, and the tail of the plug can pass through the through hole and extend out of the shell cover.

[0021] Further, the opening and closing mechanism further includes a fiber block, which is used to apply pressure to the tail of the plug and export the primer.

[0022] Further, the fiber block is in a flat shape with a narrowed top and is made of any one of acrylic fiber, polystyrene fiber, polyethylene fiber, wood fiber or polyester fiber.

[0023] The material of the fiber block needs to fill the voids. On the one hand, these voids lead the primer from the container to the substrate; on the other hand, a large number of fibers prevent the primer from flowing out of the container too quickly, thereby reducing the service life of the product. The material of the fiber block also needs to have the following characteristics: 1. Good compatibility with the primer, not being corroded or dissolved; 2. Good rigidity, not being deformed or collapsed under external force; 3. Good wettability, being quickly wetted by the solvent primer; 4. Not affecting the performance of the primer.

[0024] Further, the material of the fiber block is white polyester fiber material.

[0025] Further, the container body includes a tube body and an inner lid. Both the tube body and the inner lid are made of any one of polystyrene, ABS plastic, polyvinyl chloride, polyester, polyamide or polyethylene, and can be hermetically combined by threads. The inner lid has an outlet for leading the primer outwards, and the fiber block extends out from the outlet of the inner lid.

[0026] The inner wall of the tube body has threads, and its material has the following characteristics: 1. Excellent airtightness, ensuring that the primer will not leak out of the tube body; 2. Good compatibility with the primer, not being corroded or dissolved, and not affecting the performance of the primer.

[0027] The outer wall of the inner lid has threads, and its material has the following characteristics: 1. Combined with the tube body by threads, having a certain sealing property; 2. Good compatibility with the primer, not being corroded or dissolved, and not affecting the performance of the primer.

[0028] Further, the tube body and the inner lid are made of any one of translucent polyvinyl chloride, polyester, polyamide or polyethylene. For the convenience of observing the content of the primer in the container and for aesthetics, the tube body and the inner lid are made of translucent materials.

[0029] Further, the tube body and the inner cap are made of translucent polyethylene material.

[0030] Further, the inner cap is provided with a sponge pad, and the sponge pad is provided with rectangular holes matching the fiber blocks, and the fiber blocks pass through the sponge pad through the rectangular holes.

[0031] The sponge pad is circular and has the same size as the inner part of the inner cap. When the channel of the plug is opened for too long and too much primer flows out while the fiber blocks are not fast enough to adsorb it, the sponge pad can help adsorb the remaining primer to prevent the primer from leaking; at the same time, the sponge pad can also play a buffering role during the pushing or sliding process of the fiber blocks.

[0032] Further, the container body further includes an outer cap, and the outer cap is made of any one of translucent polystyrene, ABS plastic, polyvinyl chloride, polyester, polyamide or polyethylene, and can be hermetically combined with the inner cap to protect the fiber blocks from being damaged when not in use.

[0033] The outer cap is made of a translucent material and can protect the fiber blocks from being damaged under normal circumstances. These materials have the following characteristics: 1. Have a certain airtightness when combined with the tube body; 2. Have good compatibility with the primer, are not corroded or dissolved, and do not affect the performance of the primer.

[0034] Further, the outer cap is made of any one of translucent polyvinyl chloride, polyester, polyamide or polyethylene.

[0035] Further, the outer cap is made of translucent polyethylene material.

[0036] The part of the outer wall of the inner cap in contact with the outer cap is provided with an annular protrusion, and through this annular protrusion, the inner cap and the outer cap can be tightly combined.

[0037] For the liquid primer packaging provided by the present invention, the key lies in controlling the primer outlet through a spring. When pressing the white fiber blocks, the fiber blocks drive the plug to move inward, the channel is opened, and the solvent primer flows out from the channel to soak the white fiber blocks; when the pressing of the white fiber blocks ends, the plug is not affected by external forces other than the spring, and the spring rebounds to block the channel, so that the solvent primer cannot flow out, achieving the effect of preserving the solvent primer.

[0038] For the liquid primer packaging provided by the present invention, the requirements for the packaging material are relatively high. It must have good compatibility with the primer, not be corroded or dissolved, and not affect the performance of the primer. At the same time, it can also maintain an airtight package, and the primer will not be lost even if not used for a long time.

[0039] The beneficial effects of the present invention are as follows: The present invention provides a brand-new and convenient liquid primer packaging, including a tube body, an inner cap, a plug, a fiber block, and an outer cap. According to the special properties of the primer, a specific structure is designed and specific materials are used for preparation. This packaging has the characteristics of being convenient to carry and use, not requiring the borrowing of other tools for brushing, saving the primer, and not polluting the surrounding substrates. At the same time, the materials of this packaging have good compatibility with the primer, are not corroded or dissolved, do not affect the performance of the primer, and ensure good airtightness to ensure that the primer will not leak out. This packaging is very suitable for the DIY industry and is a special packaging for liquid primers. BRIEF DESCRIPTION OF THE DRAWINGS

[0049] Example 1 Liquid primer packaging provided by the present invention

[0050] The structural schematic diagram of the liquid primer packaging provided in this example is as shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 ,Figure 6 and Figure 7 as shown, where Figure 1 is a schematic view of the appearance of the liquid primer packaging Figure 2 is a schematic structural view of the components of the liquid primer packaging separated Figure 3 is a structural view of the fiber block of the liquid primer packaging Figure 4 is a structural view of the inner cap of the liquid primer packaging Figure 5 is a structural view of the sponge pad of the liquid primer packaging Figure 6 is a structural view of the plug of the liquid primer packaging Figure 7 is a schematic structural view of the components of the plug of the liquid primer packaging separated Figure 8 is a sectional view of the liquid primer packaging

[0051] The liquid primer packaging provided in this embodiment includes a container body 1 and an opening and closing mechanism 2. The container body 1 includes a tube body 3, an inner cap 4, a sponge pad 5 in the inner cap, and an outer cap 6. The opening and closing mechanism 2 includes a plug 7 and a fiber block 8

[0052] As Figure 6 and 7 shown, the plug 7 is composed of a housing 9, a plug pin 10, and a spring 11. The housing 9 and the plug pin 10 are both preferably made of polyethylene

[0053] Preferably, the housing 9 has an open channel 12, and the plug pin 10 has a snap ring 13 that can completely cover the channel 12

[0054] Preferably, the plug pin 10 includes a front end 14, a snap ring 13, and a tail 15. The snap ring 13 is located between the front end 14 and the tail 15, and the front end 14 is sleeved with the spring 11. When an external force acts on the tail 15 of the plug pin, the plug pin 10 moves inward, the spring 11 is compressed, the snap ring 13 leaves the channel 12, and the channel 12 is opened. When the external force is removed, the spring 11 rebounds, the plug pin 10 resets, and the snap ring 13 just completely covers the channel 12, and the channel 12 is closed

[0055] Preferably, the housing 9 includes a shell body 16 and a shell cover 17. The shell cover 17 is a hollow structure with a frustum 18 that mates with the upper part of the shell body. The outer wall of the frustum 18 is provided with an annular protrusion 19 that can fit tightly with the shell body 16. The through hole 12 is located at the center of the top of the frustum 18, and the tail 15 of the plug pin can pass through the through hole 12 and extend out of the shell cover 17 from the frustum 18

[0056] As Figure 3 shown, the fiber block 8 is flat, with a narrowed top 20, and is preferably made of white polyester fiber. The fiber block 8 is used to apply pressure to the tail 15 of the plug pin and discharge the primer

[0057] As Figure 1 、 2As shown in Figures 4 and 8, both the tube body 3 and the inner cap 4 are made of translucent polyethylene material and can be hermetically combined by threads. The inner cap 4 has an outlet 21 for discharging the primer outward, and the fiber block 8 extends from the outlet 21 of the inner cap 4. A sponge pad 5 is installed inside the inner cap 4. As Figure 5 shown, the sponge pad 5 has a rectangular hole 22 that matches the fiber block 8, and the fiber block 8 passes through the sponge pad 5 through the rectangular hole 22. The outer cap 6 is made of translucent material and can be hermetically combined with the inner cap 4 to protect the fiber block 8 from damage when not in use. The part of the outer wall of the inner cap 4 in contact with the outer cap 6 is provided with an annular protrusion 23, and the inner cap and the outer cap can be tightly combined through the annular protrusion 23.

[0058] Example 2 Selection of Fiber Block Materials

[0059] In this example, the primer used is the TEK7649AA model primer of Saint-Gobain (China) Investment Co., Ltd. Eight materials, namely polypropylene fiber, polystyrene fiber, acrylic fiber, polyacrylonitrile fiber, polyamide fiber, polyethylene fiber, wood fiber, polyester fiber, and polyethylene fiber, are selected to prepare the fiber block, and the adsorption and compatibility of each material with the primer need to be investigated.

[0060] Accurately weigh 100 g (M0) of each material and place it in a beaker. Then add a sufficient amount of primer to each beaker and soak for a period of time. After each material is saturated with the primer, record the adsorption time t. Filter out the excess primer with a standard sieve and dry the surface of the adsorbed material, and weigh it as M1. Calculate the primer adsorption ratio Q and the primer adsorption rate V according to the following formulas respectively: Q = (M1 - M0) / M0, V = (M1 - M0) / (M0×t), and let it stand for more than 24 hours, and observe whether there is corrosion and dissolution on its surface. The results are shown in Table 1.

[0061] Table 1 Adsorption Properties and Compatibility of Different Materials with the Primer

[0062] Material Adsorption ratio Adsorption rate Compatibility Polypropylene 183 2.8 Slight corrosion phenomenon Polystyrene fiber 403 11.5 No corrosion and dissolution phenomenon Acrylic fiber 415 9.9 No corrosion and dissolution phenomenon Polyacrylonitrile fiber 236 5.1 Slight corrosion phenomenon Polyamide fiber 247 4.7 Slight corrosion phenomenon Polyethylene fiber 437 12.7 No corrosion and dissolution phenomenon Wood fiber 421 10.3 No corrosion and dissolution phenomenon Polyester fiber 451 13.8 No corrosion and dissolution phenomenon

[0063] As can be seen from Table 1, the materials that have good compatibility with the primer, no corrosion and dissolution phenomenon, and are suitable for preparing the fiber block for primer packaging are acrylic fiber, polystyrene fiber, polyethylene fiber, wood fiber, and polyester fiber. Among them, the polyester fiber has the best adsorption performance for the primer, with the highest adsorption ratio and adsorption rate. Therefore, using polyester fiber to prepare the fiber block for primer packaging is the best choice.

[0064] Example 3 Selection of Container Packaging Materials

[0065] In this embodiment, the primer used is the TEK7649AA primer of Saint-Gobain (China) Investment Co., Ltd. Initially, 8 materials including polystyrene, ABS plastic, polypropylene, polyvinyl chloride, polyester, polyacrylonitrile, polyamide, and polyethylene were selected to prepare the tube body, inner cap, plug, and outer cap of the liquid primer packaging provided in Example 1. It is necessary to investigate the compatibility of each material with the primer (according to the experimental method of Example 2), as well as the airtightness of the solvent packaging material with the primer (the experimental method is: place the product in an environment of 60 °C for 28 days and detect the mass loss rate). The investigation results are shown in Table 2.

[0066] Table 2 Selection of Container Packaging Materials

[0067]

[0068]

[0069] It can be seen from Table 1 that considering the airtightness and compatibility with the primer, polystyrene, ABS plastic, polyvinyl chloride, polyester, polyamide, and polyethylene can be used. Considering comprehensively, polyethylene is used to make the tube body, inner cap, plug, and outer cap of the primer packaging material. Considering airtightness, polyvinyl chloride, polyester, polyamide, and polyethylene are preferred, and polyethylene is the most preferred, with the best airtightness, a mass loss rate of only 10.0%, and more suitable stiffness and elasticity. Therefore, the liquid primer packaging material is most preferably polyethylene.

[0070] Example 4 Airtightness Investigation

[0071] The airtightness of the primer pen has a decisive impact on the practicability and service life of the product. The primer is generally a low-boiling volatile substance, and such substances are very easy to volatilize at room temperature. During the storage, transportation, and sale of the product, high-temperature environments (≥35 °C) will inevitably occur; if the airtightness is poor, the primer will quickly volatilize, thus affecting the performance and service life of the product.

[0072] To ensure that the product has the best performance, the research team conducted a large number of material selections and tests for this problem. In this embodiment, the liquid primer packaging provided in Example 1 is used, where the fiber block is made of polyester fiber, and the tube body, inner cap, plug, and outer cap are all made of polyethylene. Now, the research team can place the product in environments of 60 °C and 25 °C respectively for 28 days; the results show that the amounts of primer lost are 10% and 1% respectively.

[0073] The compatibility of the packaging with the primer is also a very crucial influencing factor. During the above airtightness test process, we did not find any adverse effects on each other between the primer and the packaging material. The performance of the primer did not change at all, and the packaging did not change either.

[0074] Although the present invention is disclosed as above, the present invention is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the scope defined by the claims.
