Description

Technical Field

[0001] The present invention relates to a cutting valve for realizing internal cutting in an inner container and an aerosol container containing the cutting valve, belonging to the technical field of aerosol container design. Background Art

[0002] An aerosol is an aerosol commodity produced in the modern fine chemical industry, which has the advantages of small volume, convenient to carry, simple to use, uniform distribution of the ejected material, and can fully exert the application effect. It has been widely used in the fields of insect killing, sterilization, medical and health, mechanical lubrication, non-destructive flaw detection of materials, etc.

[0003] Among them, when using aerosol paint or certain medicaments, two different materials need to be mixed on-site and used up within a short time. This requires storing the two materials separately during the production process. For more convenient use, generally, such two materials are stored in the same container and separated from each other. When in use, the bottom of the inner container is punctured through a puncturing valve, so that the material in the inner container flows out, and then is mixed with the material outside the inner container, and then is ejected through another valve; the specific technical solution of making the material in the inner container flow out by setting a puncturing valve can be detailed in the patent application with the application number 201510036599.9, that is: a stamping shear cut that can be punctured is provided at the lower end of the inner container, a connecting rod is provided in the valve chamber of the puncturing valve mechanism, a punch that can puncture the stamping shear cut is connected to the lower end of the connecting rod, and a valve rod that can drive the connecting rod to move downward so that the punch punctures the stamping shear cut is provided in the valve chamber at the upper end of the connecting rod. When it is necessary to mix the two materials, pressure is applied to the upper end of the connecting rod to press down the punch to puncture the stamping shear cut. In this way, the material in the inner container can enter the container and be mixed with another material. Because this technology requires presetting a stamping shear cut that can be punctured at the lower end of the inner container in advance, the processing accuracy requirements for this stamping shear cut are very high, and it is very easy to have problems such as either it cannot be punctured by stamping, or during transportation, the stamping shear cut is damaged by the material outside the inner container, resulting in premature mixing and failure; in addition, the puncturing valve structure is very complex, the processing cost is very high, and it occupies a large volume, reducing the effective volume of the inner container. Summary of the Invention

[0004] Aiming at the above problems existing in the prior art, the purpose of the present invention is to provide a cutting valve for realizing internal cutting in an inner container and an aerosol container containing the cutting valve, which is simple in processing and low in cost, can meet the use requirements and convenience, and has transportation safety and small occupied volume, so as to solve the packaging problem of aerosol products that require on-site mixing of two materials.

[0005] To achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A cutting valve for realizing in-tank cutting, comprising a sealing cup that can be hermetically connected to the opening of the inner tank. A rotating shaft is passed through the center of the sealing cup. A cutting valve body assembly is sleeved on the shaft body of the rotating shaft at the top of the sealing cup. The cutting valve body assembly is provided with a cutting blade that can contract and extend. When the cutting blade is in the contracted state, there is a gap between the tip of the cutting blade and the inner wall of the inner tank. When the cutting blade is in the extended state, the tip of the cutting blade will penetrate outside the wall of the inner tank.

[0007] An implementation scheme, the cutting valve body assembly is further provided with a cutting tool holder, a cam, a cam mounting seat and a fixed seat. The cam mounting seat is provided with an opening groove adapted to the cam. The cam is located in the inner cavity of the opening groove. The cutting tool holder is rotatably connected to the opening side of the opening groove. The cutting blade is fixedly arranged on the front outer side surface of the cutting tool holder. The fixed seat is fixedly connected to the sealing cup. The centers of the cam, the cam mounting seat and the fixed seat are all provided with shaft holes adapted to the shaft body of the rotating shaft. The cam mounting seat, the cam and the fixed seat are sequentially sleeved on the shaft body of the rotating shaft from top to bottom. And, a limiting column is arranged at the bottom of the front end of the cutting tool holder, and a limiting notch is arranged on the circumferential side surface of the fixed seat. When the limiting column is located in the limiting notch, there is a gap between the tip of the cutting blade and the inner wall of the inner tank. When the limiting column leaves the limiting notch and is located on the outer circumferential surface of the cam mounting seat, the tip of the cutting blade will penetrate outside the wall of the inner tank.

[0008] A preferred scheme, a limiting card slot and a limiting card are arranged on the shaft body at the top of the cam mounting seat.

[0009] An implementation scheme, a through hole is arranged at the center of the sealing cup. The bottom of the fixed seat is provided with a boss whose outer diameter is adapted to the inner diameter of the inner cavity of the through hole. A shaft hole adapted to the shaft body of the rotating shaft is arranged at the center of the boss.

[0010] A preferred scheme, a sealing ring Ⅰ is arranged between the boss and the rotating shaft.

[0011] A preferred scheme, the diameter of the head of the rotating shaft is larger than the inner diameter of the shaft hole on the sealing cup.

[0012] A further preferred scheme, a manual operation ring is arranged at the head of the rotating shaft.

[0013] A preferred scheme, the sealing cup is made of tinplate, and the rotating shaft and the cutting valve body assembly are both made of engineering plastic.

[0014] An aerosol container containing the above-mentioned cutting valve, comprising a container for containing a first material and an inner container for containing a second material. The inner container is located inside the container, and the open end of the inner container is hermetically connected to one end of the container. A spray valve assembly communicating with the inner cavity of the container is hermetically arranged at the other end of the container, and the above-mentioned cutting valve is hermetically installed at the open end of the inner container.

[0015] An embodiment, wherein the container is a tinplate spray can, and the inner container is an aluminum inner container.

[0016] Compared with the prior art, the present invention has the following beneficial technical effects:

[0017] Since the cutting valve provided by the present invention can achieve cutting inside the inner container, when an aerosol container with the cutting valve of the present invention hermetically installed at the open end of the inner container needs to mix two materials on-site, only by rotating the rotating shaft therein to drive the cam movement, the cutting blade can make a cutting circular motion on the inner wall of the inner container under the drive of the cam, so that the main part of the inner container containing the second material is cut off and dropped, and then the second material in the inner container can be quickly mixed with the first material contained in the container. It not only has high mixing efficiency but also is very simple to operate; in particular, by using the cutting valve of the present invention, there is no need to reserve a stamping shear cut at the lower end of the inner container, which not only reduces the processing difficulty and cost of the inner container but also ensures the transportation safety of the aerosol; moreover, the cutting valve of the present invention occupies a small volume, so that the effective volume of the inner container can be significantly increased compared with the prior art; in addition, the structures of the cutting valve and the aerosol container of the present invention are very simple and are easy to realize large-scale, low-cost processing and assembly; therefore, compared with the prior art, the present invention not only has obvious practical value but also has remarkable progressiveness, and creatively solves the packaging problem of aerosol products that need to mix two materials on-site.

[0034] Embodiment

[0035] Please refer to Figure 1 , Figure 8 , Figure 10 and Figure 11 as shown: A cutting valve 1 for realizing in-tank cutting provided in this embodiment includes a sealing cup 1-1 that can be hermetically connected to the opening of the inner tank 2. A rotating shaft 1-2 is passed through the center of the sealing cup 1-1. A cutting valve body assembly 1-3 is sleeved on the shaft body of the rotating shaft 1-2 at the top of the sealing cup 1-1. A retractable and extendable cutting blade 1-31 is provided on the cutting valve body assembly 1-3. When the cutting blade 1-31 is in the retracted state, there is a gap between the tip 1-311 of the cutting blade 1-31 and the inner wall of the inner tank 2 (please refer to Figure 1 and Figure 8 as shown). When the cutting blade 1-31 is in the extended state, the tip 1-311 of the cutting blade 1-31 will penetrate outside the wall of the inner tank 2 (please refer to Figure 10 and Figure 11 as shown).

[0036] Please refer to Figures 1 to 7 as shown again. In this embodiment, the cutting valve body assembly 1-3 further includes a cutting tool holder 1-32, a cam 1-33, a cam mounting seat 1-34, and a fixed seat 1-35. The cam mounting seat 1-34 is provided with an open groove 1-341 adapted to the cam 1-33. The cam 1-33 is located in the inner cavity of the open groove 1-341. The cutting tool holder 1-32 is rotatably connected to the opening side of the open groove 1-341. The cutting blade 1-31 is fixedly provided on the front outer side of the cutting tool holder 1-32. The fixed seat 1-35 is fixedly connected to the sealing cup 1-1. The centers of the cam 1-33, the cam mounting seat 1-34, and the fixed seat 1-35 are all provided with shaft holes 1-331, 1-342, and 1-351 adapted to the shaft body of the rotating shaft 1-2. The cam mounting seat 1-34, the cam 1-33, and the fixed seat 1-35 are sequentially sleeved on the shaft body of the rotating shaft 1-2 from top to bottom; and, a limiting post 1-321 is provided at the bottom of the front end of the cutting tool holder 1-32, and a limiting notch 1-352 is provided on the circumferential side of the fixed seat 1-35.

[0037] When the limit post 1-321 is located in the limit notch 1-352, there is a gap between the tip 1-311 of the cutting blade 1-31 and the inner wall of the inner container 2 (as Figure 8 shown); when the limit post 1-321 leaves the limit notch 1-352 and is located on the outer peripheral surface of the cam mounting seat 1-34, the tip 1-311 of the cutting blade 1-31 will penetrate outside the wall of the inner container 2 (as Figure 10 shown).

[0038] Please refer to Figure 4 again: In this embodiment, the cup cover 1-1 has a protrusion 1-11 adapted to the open inner cavity of the inner container 2. A sealing groove 1-12 capable of sealingly connecting with the opening edge of the inner container 2 is provided at the outer peripheral bottom of the protrusion 1-11. And a through hole 1-13 for connecting with the fixed seat 1-35 and a shaft hole 1-14 for the shaft of the rotating shaft 1-2 to pass through are provided at the center of the protrusion 1-11.

[0039] Please refer to Figure 5 again: In this embodiment, the bottom of the fixed seat 1-35 is provided with a boss 1-353 whose outer diameter is adapted to the inner diameter of the through hole 1-13. A shaft hole 1-351 adapted to the shaft of the rotating shaft 1-2 is provided at the center of the boss 1-353. A limit notch 1-352 is provided on the peripheral side surface of the fixed seat 1-35.

[0040] Please refer to Figure 6 again: In this embodiment, the cam mounting seat 1-34 is provided with an open groove 1-341 adapted to the cam 1-33. A pin shaft 1-343 for rotatably connecting the cutting tool holder 1-32 is provided on the opening side of the open groove 1-341. And a shaft hole 1-342 for the shaft of the rotating shaft 1-2 to pass through is provided at the center of the cam mounting seat 1-34.

[0041] Please refer to Figure 7 again: In this embodiment, the cam 1-33 is assembled in the inner cavity of the open groove 1-341. The cutting tool holder 1-32 is rotatably connected to the opening side of the open groove 1-341 through the pin shaft 1-343. In the initial state, the tip 1-311 of the cutting blade 1-31 is located inside the outer peripheral surface of the cam mounting seat 1-34, that is: there is a gap between the tip 1-311 of the cutting blade 1-31 and the inner wall of the inner container 2 (please refer to Figure 8 shown).

[0042] When the rotating shaft 1-2 rotates, the cam 1-33 will rotate accordingly, thereby pushing out the cutting tool holder 1-32 by extrusion. As a result, the limit post 1-321 on the cutting tool holder 1-32 will leave the limit notch 1-352 and be located on the outer peripheral surface of the cam mounting seat 1-34. At this time, the tip 1-311 of the cutting blade 1-31 has protruded from the outer peripheral surface of the cam mounting seat 1-34 (please refer to Figure 11 as shown), so as to penetrate through the wall of the inner container 2 (please refer to Figure 9 and Figure 10 as shown). As the rotating shaft 1-2 continues to rotate, the cutting blade 1-31 will perform a cutting circular motion on the inner container 2, thereby cutting the inner container 2 from the inside to the outside.

[0043] As a preferred solution:

[0044] A limit card slot 1-21 and a limit card 1-4 are provided on the shaft body at the top of the cam mounting seat 1-34 to position the cutting valve body assembly 1-3;

[0045] A sealing ring Ⅰ1-354 is provided between the boss 1-353 and the rotating shaft 1-2 to achieve a sealed connection between the rotating shaft 1-2 and the sealing cup 1-1;

[0046] A sealing ring Ⅱ1-15 is provided in the edge sealing groove 1-12 to achieve a sealed connection between the edge sealing of the opening of the inner container 2 and the sealing cup 1-1;

[0047] The diameter of the head of the rotating shaft 1-2 is larger than the inner diameter of the shaft hole 1-14 on the sealing cup 1-1, and a manual operation ring 1-5 is provided at the head of the rotating shaft 1-2 for easy extraction and applying a rotational force to the rotating shaft;

[0048] The sealing cup 1-1 can be formed from tinplate material, and the rotating shaft 1-2 and the cutting valve body assembly 1-3 can both be formed from engineering plastic material.

[0049] Please refer to Figure 12 and Figure 13 as shown:

[0050] An aerosol container containing the cutting valve capable of realizing cutting inside the inner container according to the present invention includes a container 3 for containing the first material and an inner container 2 for containing the second material. The inner container 2 is located inside the container 3 and the open end of the inner container 2 is sealedly connected to one end of the container 3. The cutting valve 1 is sealedly installed at the open end of the inner container 2. A spray valve assembly 4 communicating with the inner cavity of the container 3 is sealedly provided at the other end of the container 3; the spray valve assembly 4 adopts known technology and is not an improvement point of this application, so no detailed description will be given here.

[0051] The container 3 is preferably a tinplate spray can, and the inner container 2 is preferably an aluminum inner container.

[0052] When two materials need to be mixed on site, just rotate the rotating shaft 1-1 in the cutting valve 1 installed at the open end of the inner tank 2, and the cutting blade 1-31 therein can perform a cutting circular motion on the inner tank 2, so that the inner tank 2 is cut off from the inside to the outside, thereby realizing the mixing of the second material contained in the inner tank 2 and the first material contained in the container tank 3, and then spraying and using through the spray valve assembly 4.

[0053] In summary, it can be seen that: by using the cutting valve provided by the present invention, internal cutting of the inner tank can be realized, and rapid mixing of the second material contained in the inner tank and the first material contained in the container tank can be achieved. It not only has high mixing efficiency but also is very simple to operate; in particular, by using the cutting valve of the present invention, there is no need to reserve a stamping shear cut at the lower end of the inner tank, which not only reduces the processing difficulty and cost of the inner tank but also ensures the transportation safety of the aerosol; moreover, the cutting valve of the present invention occupies a small volume, so that the effective volume of the inner tank can be significantly increased compared with the prior art; in addition, the structures of the cutting valve and the aerosol container of the present invention are very simple and are easy to realize large-scale, low-cost processing and assembly; therefore, compared with the prior art, the present invention not only has obvious practical value but also has significant progressiveness, and creatively solves the packaging problem of aerosol products that require on-site mixing of two materials.

[0054] Finally, it is necessary to point out here that: the above description is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
