Definitions
- the present invention relates to an injection button that injects contents, and more particularly to an injection button that is attached to an aerosol container and injects aerosol contents and is a mechanical breakup type injection button.
- a mechanical breakup button has been used as an injection button that satisfies the demand for reducing the spray particle diameter of the aerosol contents or injecting the contents over a wide range.
- the mechanical breakup button is known as a mechanism that finely and uniformly injects particles by applying a turning force to the contents in the vicinity of the injection port and injecting it from the injection port, and is particularly effective when the propellant is a compressed gas. It is.
- a conventional mechanical break-up button has a tip that fits into the recess of the injection button, a spray passage is formed on the peripheral surface of the tip, and a swirl chamber is formed from a groove formed on the front end of the tip or the inner surface of the nozzle body. After that, various devices are known so as to inject at a wide angle while rotating from the injection port (see, for example, Patent Documents 1 and 2).
- the mechanical break-up type injection button is effective for wide-angle injection, but the injection angle of the conventional injection button is not more than 80 °, and only within 90 ° at most is practically used. Therefore, conventionally, for example, hair products such as hair sprays, horticultural insecticides or deodorants for garbage, etc., in spraying the contents with compressed gas or liquefied gas, in order to achieve a good coating effect, more wide-angle spray and particle Although miniaturization is demanded, it has not been satisfied yet.
- An object of the present invention is to provide an injection button that can inject contents at a wide angle over a wide range, reduce the diameter of the injection particles, and has a simple structure.
- the inventor has various dimensions constituting the injection button schematically shown in FIG. Among them, the injection port diameter Da, the swirl chamber diameter D, the length L from the stem side wall of the nozzle body to the tip of the spray port, the land length La of the spray port, the swirl chamber thickness Lb, the spray groove width Dd, the spray groove depth Focusing on the number of injection grooves, the ratio D / Da between the swirl chamber diameter D and the injection port diameter Da, the ratio D / Dd between the swirl chamber diameter D and the injection groove width Dd, the swirl chamber diameter D and the nozzle body in particular. It is predicted that the three elements of the ratio D / L with the length L from the stem side wall to the tip of the injection port will greatly affect the injection angle and the particle diameter of the contents, and how these values affect the injection angle. The effect was analyzed by numerical analysis.
- the graph shown in FIG. 4 is a numerical analysis of the effect of the ratio D / Dd between the swirl chamber diameter D and the injection groove width Dd on the injection angle.
- the dimensions other than the injection groove width Dd were fixed, the swirl chamber diameter D and the injection groove width Dd were changed to change D / Dd, and the injection angle at that time was obtained.
- the graph shown in FIG. 5 shows the injection when changing the D / L value while fixing the dimensions other than the swirl chamber diameter D and the length L from the stem side wall of the nozzle body to the tip of the injection port. The effect on the angle was investigated by numerical analysis.
- FIG. 6 shows the result of numerical analysis of the influence of the land length La on the injection angle with fixed dimensions except for the land length La, and it is understood that the shorter the land length La, the wider the angle injection. It was. The angle change increases as the land length La approaches 0 mm.
- FIG. 7 shows the result of numerical analysis of the influence of the injection groove width Dd on the injection angle with the fixed dimensions other than the injection groove width Dd. As the injection groove width becomes narrower, wide angle injection can be obtained. I understood.
- an injection button according to a first aspect of the present invention that solves the above problem is a spray button having a swirl chamber, an injection port, and a plurality of injection grooves.
- the swirl chamber diameter D, the injection port diameter Da, and the connection between the injection groove and the swirl chamber When the width Dd of the part and the length L from the stem side wall of the nozzle body to the tip of the injection port are set as follows: i) D / Da> 1, ii) D / Dd ⁇ 5, iii) D / L ⁇ 3 It is characterized by satisfying.
- the swirl chamber diameter is equal to or smaller than the injection port diameter, that is, if D / Da ⁇ 1, it is difficult to cause the contents to rotate and wide angle injection cannot be performed.
- Da> 1, preferably D / Da ⁇ 3.
- D / Dd ⁇ 5 the contents cannot be sufficiently rotated in the swirl chamber, so that wide-angle injection cannot be performed and the particles cannot be atomized, so D / Dd ⁇ 5.
- the length L from the side wall on the stem side to the tip of the injection port is long with respect to the diameter of the swirl chamber, the flow resistance of the contents becomes large and the rotation is lost and the relationship with D / L is injected. Therefore, in order to achieve an injection angle of 90 ° or more, D / L ⁇ 3 must be satisfied.
- the spray button of the present invention further has a land length of the spray port of 0.3 mm or less, a length from the stem side wall of the swirl chamber to the tip of the spray port of 0.6 mm or less, More preferably, the diameter is 1.5 mm to 3.0 mm, and the width of the connecting portion between the spray groove and the swirl chamber is 0.1 mm to 0.3 mm. And it is desirable that there are three or more injection grooves.
- the said injection button can be used suitably for the container injected with compressed gas.
- FIG. 1 is a schematic front sectional view of a spray button according to an embodiment of the present invention.
- the injection button 1 according to the present embodiment is composed of a combination of two pieces of an injection button main body 2 and a nozzle body 3, and the nozzle body 3 is assembled by being fitted to the protrusion 4 of the injection button main body 2.
- the injection button main body 2 is integrally formed of synthetic resin, and an inflow path 6 into which a container stem is fitted is formed in the center part. And the communicating hole 7 substantially orthogonal to the inflow path 6 is formed.
- the nozzle body 3 is composed of a nozzle base 14 and an annular wall 15 formed to project from the back surface (stem side) of the nozzle base. As shown in FIG. 1, the annular wall 15 is formed to a length that fits partway through the annular groove 8. A plurality of (three in the illustrated embodiment) passages 16 are formed along the outer peripheral surface of the projecting portion 4 at equal intervals on the inner peripheral surface of the annular wall 15, and the base end portion is the stem of the nozzle body. It communicates with the injection groove 17 formed on the side wall surface 23.
- the injection groove 17 is formed so as to be in contact with the outer peripheral portion of the swirl chamber 20 described later from a substantially tangential direction, and the contents are supplied to the swirl chamber 20 in the tangential direction from three directions in the present embodiment.
- a swirling flow is formed.
- the injection groove 17 is formed so as to become narrower as it reaches the connecting portion 18 with the swirl chamber.
- the ejection groove 17 is formed on the stem side wall surface 23 of the nozzle body, but can also be formed on the distal end surface of the projecting portion 4 of the ejection button body.
- the swirl chamber 20 is formed as a circular recess on the back surface of the nozzle base and is formed between the tip surface of the protrusion 4 of the injection button main body 2. In this embodiment, it is formed as a circular recess, but it may be formed as a dome shape or a truncated cone recess.
- An injection port 21 is formed through the nozzle base 14 from the center of the swirl chamber 20. As shown in FIG. 1, in the present embodiment, the injection port 21 is formed with a dome-shaped recess 22 on the surface of the nozzle base, and is opened at the center of the bottom so that a good wide-angle injection of the contents can be performed.
- the injection button according to the present embodiment has the above-described structure, is attached to a stem of a container (not shown), and presses downward to push the stem down, thereby opening the valve to pressurize gas, liquefied gas, or trigger. Due to the pressure of the pump, it flows from the inflow passage 6 through the annular groove 8 and from the tip through the liquid passage 16 formed in the inner peripheral surface of the annular wall into the swirl chamber from the tangential direction at three-degree positions at 120 ° intervals. The contents flow into the swirl chamber from three directions in the tangential direction at high pressure, and as a strong swirl flow in the swirl chamber, the contents are jetted to the outside while maintaining rotation. At that time, the contents can be crushed into fine particles during the rotation process and injected at a predetermined injection angle.
- the land length La of the injection port 21 is 0.3 mm or less
- the length L from the stem-side side wall surface 23 of the swirl chamber 20 to the spray port front end surface 24 is 0.6 mm or less
- the diameter D of the swirl chamber is
- the width of the connecting portion 18 between the injection groove 17 and the swirl chamber 20 is 1.5 mm to 3.0 mm, and the width is within the range of 0.1 mm to 0.3 mm.
- the land length La is preferably short so as not to give flow resistance at the time of injection to the contents rotated in the swirl chamber, but if the land length is less than 0.1 mm, durability is insufficient.
- the range of 0.1 mm or more and 0.3 mm is desirable.
- the present inventor conducted experiments and numerical analysis by changing the land length La in the range of 0.2 to 0.7. In an example described later, an injection angle of 90 ° or more can be realized at 0.2 mm. However, in the range of 0.3 mm to 0.7, only an injection angle in the range of 48 ° to 80 ° was obtained.
- the length L from the stem-side side wall surface 23 of the swirl chamber 20 to the injection nozzle tip end surface 24 should be as short as possible in order to reduce the flow resistance of swirl flow as in the case of the land length La. 0.6 mm or less is preferable, but considering the strength of the injection port 21 and the thickness forming the swirl chamber, the range of 0.3 to 0.6 mm is preferable. Similarly, according to numerical calculations and experiments, a good injection angle could not be obtained in a range where L was 0.65 to 1.15 mm.
- the diameter D of the swirl chamber is desirably larger to form a swirl flow, but if it is increased, the diameter of the nozzle body has to be increased, so a range of 1.5 mm to 3.0 mm is desirable. If the swirl chamber diameter D is 1.5 mm or less, it is difficult to form a strong swirl flow, and wide-angle injection cannot be performed. Further, it is more preferable that the width of the connecting portion between the spray groove and the swirl chamber is 0.1 mm to 0.3 mm. As described above, the width of the connecting portion has a relative relationship with the diameter of the swirl chamber as described above, and when the diameter of the swirling chamber is 1.5 mm to 3.0 mm, the width of the connection portion. Is preferably in the range of 0.1 mm to 0.3 mm. In order to cause uniform high-speed swirling of the contents in the swirl chamber 20, it is desirable that there are three or more spray grooves.
- the injection button of the present embodiment can be applied to a container that injects various contents, particularly an aerosol container that is injected with compressed gas, and nitrogen, carbon dioxide, nitrous oxide, or the like can be used as the compressed gas. Further, the contents can be suitably applied to the injection of aerosol contents having a viscosity of 100 cp or less, and these contents can be injected by a wide angle injection of 90 ° or more and an average particle diameter of 65 ⁇ m or less. Therefore, it is used for jetting water or alcohol-based aerosol contents, such as hair supplies such as hair sprays, horticultural insecticides or garbage deodorants, in a wider range and in a fine particle state than conventional spray buttons.
- the spray button which can be sprayed and was excellent in the application effect is obtained.
- the Lb, the injection groove width Dd, the injection groove depth, and the number of injection grooves are configured as shown in Table 1, and water having a viscosity of 1 cp is injected as the aerosol content with nitrogen at a pressure of 0.7 MPa as the compressed gas.
- the spray angle and average particle size were measured.
- the injection angle was measured from the image which image
- the average particle size was measured with a laser diffraction particle size distribution measuring device with a distance from the measurement point to the injection port being 15 cm.
- the injection angles and average particle sizes in Examples 1 and 2 and Comparative Examples 1 to 4 are shown in the graph of FIG.
- the injection angle of 90 ° in Example 1 and 95 ° in Example 2 was 90 ° or more in any of the examples, whereas the comparative example was a comparative example.
- No. 2 has an injection angle of 80 °, but the maximum is only 80 ° to 40 °.
- the average particle size of the aerosol contents was 65 ⁇ m in Example 1 and 64 ⁇ m in Example 2, and fine particles equivalent to good fine particles such as 63 ⁇ m in Comparative Example 2 and 64 ⁇ m in Comparative Example 4 were obtained.
- the injection button of the present invention was able to obtain a wide-angle injection and a sufficiently small spray particle diameter that are not found in the conventional injection button, and it was confirmed that the injection button had a high coating effect.
- the injection button of the present invention can be applied to an injection button for injecting various contents, and is particularly suitable for injecting contents with a compressed gas propellant over a wide range of 80 ° to 100 ° and with a small injection particle diameter. It is highly possible to use as an aerosol container spray button.
