Description

Technical Field

[0001] This utility model relates to the field of aerosol valve technology, and in particular to a binary aerosol valve assembly. Background Technology

[0002] The binary aerosol valve is a key component of binary packaged aerosol products. It is a valve used in binary aerosol products that can separate the raw material and the propellant, and spray the raw material in a mist form by pressing the valve during use.

[0003] Chinese patent CN216986139U discloses a novel binary packaging structure, including a pouch and a female valve mechanism, with the pouch and valve mechanism heat-sealed together. The bottom side of the pouch has a bifurcated heat-sealing structure. The bifurcated heat-sealing structure allows the bottom of the pouch to extend downwards and outwards after the additive is added, contacting the bottom of the can, thus changing the traditional suspended placement within the can. This invention designs the bottom of the pouch as a bifurcated structure, allowing the bottom of the pouch to sink and contact the bottom of the can. The connection between the fixed cap and the can is designed with a double seal to enhance the sealing effect. Furthermore, to increase the amount of additive passing through, the inlet and outlet pipes are equipped with several inlet and outlet holes, and the inlet channel at the top of the valve stem is expanded outwards, increasing the amount of additive entering the nozzle.

[0004] The aforementioned bag is heat-sealed to the female valve mechanism. During the production process, the material needs to be heated and pressure applied one by one, resulting in low production efficiency. Moreover, the heat-sealing effect may be affected by dirt at the connection point, thus reducing product quality. Utility Model Content

[0005] This utility model provides a binary aerosol valve assembly to solve the technical problem of low production efficiency caused by the current heat-sealing connection between the bag and the female valve mechanism, which requires heating and applying pressure to each material individually during the production process.

[0006] To solve the above-mentioned technical problems, this utility model discloses a binary aerosol valve assembly, including: a sealing connection mechanism and a bag. The bag is provided at the lower end of the sealing connection mechanism. The sealing connection mechanism and the bag are an integral structure. The sealing connection mechanism includes a sealing bowl, a bowl cover and a connecting part. The sealing bowl is cylindrical. The lower end of the sealing bowl is connected to the upper end of the bowl cover. The bowl cover is bowl-shaped. The upper end of the bowl cover is connected to the sealing bowl. The lower end of the bowl cover is connected to the upper end of the connecting part. The lower end of the connecting part is connected to the bag. A flow channel is provided in the connecting part. One end of the flow channel is connected to the inside of the bowl cover and the other end of the flow channel is connected to the inside of the bag.

[0007] Preferably, the sealing connection mechanism is manufactured using injection molding, and the bladder is manufactured using blow molding.

[0008] Preferably, both the sealing connection mechanism and the bladder are made of thermoplastic structural materials, including but not limited to polyethylene, polyvinyl chloride, polypropylene, and polyethylene terephthalate.

[0009] Preferably, the end of the sealing bowl away from the bowl cover has a rolled edge that is folded down.

[0010] Preferably, the diameter of the upper end of the bowl cover is larger than the diameter of the lower end of the bowl cover.

[0011] Preferably, the inner wall of the bowl cover is provided with a number of reinforcing ribs along its circumference, and the number of reinforcing ribs are distributed in a ring array about the central axis of the bowl cover.

[0012] Preferably, the connecting part is funnel-shaped near the end of the pouch, and the diameter of the upper end of the connecting part is smaller than the diameter of the lower end of the connecting part.

[0013] Preferably, the wall thickness of the connecting part is greater than the wall thickness of the pouch.

[0014] Preferably, the cross-section of the bladder has an annular wavy structure, and the sidewall of the bladder has several rib-shaped protrusions that are evenly distributed.

[0030] Example 2

[0031] Based on the above embodiment 1, the sealing connection mechanism 1 is manufactured by injection molding, and the bag 2 is manufactured by blow molding.

[0033] The working principle and beneficial effects of the above technical solution are as follows: The sealing bowl 11, the bowl cover 12, and the connecting part 13 are made by injection molding, resulting in a thicker wall for the sealing bowl 11, the bowl cover 12, and the connecting part 13, which enhances the overall structural strength of the sealing connection mechanism 1. The bag 2 is made by blow molding, resulting in a shrinkable structure for easy ejection of raw materials from the bag 2. The bag 2 can be blow molded into different shapes according to different needs. During blow molding, it can first be blow molded into a bag preform (such as...). Figure 4 As shown), and then a second blow molding process is performed to obtain the bag 2 (as shown). Figure 5As shown, both the sealing connection mechanism 1 and the pouch 2 are made of thermoplastic structural materials, including but not limited to polyethylene, polyvinyl chloride, polypropylene and polyethylene terephthalate. The preferred material is polyethylene terephthalate (PET). The sealing connection mechanism 1 and the pouch 2 are made of the same material, which can improve the reliability of the connection between the connection part 13 and the pouch 2. Compared with the existing metal sealing connection mechanism 1, the use of polyethylene material can save costs.

[0035] Based on Example 1 or 2, such as Figure 1 As shown, the sealing bowl 11 has a downward-folded rolled edge 111 at the end away from the bowl cover 12.

[0036] The working principle and beneficial effects of the above technical solution are as follows: a sealing ring is provided on the inner side of the rolled edge 111. The rolled edge 111 can seal the sealing bowl 11 and the mouth of the spray can together, which facilitates the installation of the sealing connection mechanism 1.

[0037] Example 4

[0040] The working principle and beneficial effects of the above technical solution are as follows: Several reinforcing ribs 121 are arranged along the circumference of the inner wall of the cup cover 12. The reinforcing ribs 121 can enhance the structural strength of the cup cover 12 and prevent the cup cover 12 from deforming. The reinforcing ribs 121 are also made by injection molding process and integral molding process with the cup cover 12, which can shorten the production cycle and greatly improve the production efficiency of the aerosol valve assembly.

[0043] The working principle and beneficial effects of the above technical solution are as follows: when the raw material flows through the connecting part 13, the flow rate of the raw material can be accelerated through the trumpet-shaped connecting part 13, which is conducive to the atomization of the raw material.

[0044] Example 6

[0045] Based on any one of Examples 1-5, such as Figure 1As shown, the wall thickness of the connecting part 13 is greater than the wall thickness of the pouch 2.
