JP2004217245A - Mixed ejection mechanism for container content - Google Patents

Abstract

<P>PROBLEM TO BE SOLVED: To simplify the structure of a mixed ejection mechanism for ejecting contents A, B held in separate containers to the outside space in a mixed state, and improve the mixing efficiency of both contents. <P>SOLUTION: A balance member 20 moving horizontally in response to a pressure difference between the contents is arranged in an inner space 10e of a passage member 10 for sending out the contents A, B to a content ejecting part. When the pressure of the content A is higher than that of the content B in an operation mode, the pressure difference presses a bearing part 20c of the balance member 20 to the right, and a left flow rate adjusting member 20a reduces the effective inflow sectional area of an inflow port 10j. Meanwhile, the content B flows through an open inflow port 10K into the inner space 10e, presses the pressure bearing part 20c to the left, thus narrows the inflow port 10k. Hence, the balance member 20 moves to narrow the inflow port for either of the contents A, B of higher pressure, so that a supply ratio between both contents sent out to a space 10h for mixed ejection is made constant. A mixed ejection mechanism to improve a mixing efficiency by rolling or making turbulent the contents is also provided. <P>COPYRIGHT: (C)2004,JPO&NCIPI

Are respectively shown.
The solid arrow indicates the flow of the content A, and the broken arrow indicates the flow of the content B.
[0021]
As shown in FIG. 1 and FIG.
-Two aerosol containers 1 and 2 containing contents A and B,
A cover body 3 for integrating the two aerosol containers;
A passage member 10 of the contents accommodated in the cover body and fitted to the stems 1a, 2a of the aerosol containers 1, 2;
A balance member 20 provided in the internal space 10e of the passage member and connecting the left valve member 20a, the right valve member 20b, and the pressure receiving portion 20c by a shaft portion 20d;
An operation member 4 attached to the cover body 3 and pressing the passage member 10 (stems 1a, 2a);
The content discharging unit 5 attached to the passage member 10;
It is composed of
[0022]
Here, the passage member 10 includes a T-shaped tubular portion 10a and two L-shaped tubular portions 10b and 10c, and the three members are integrated by ultrasonic welding, fitting, assembly, or the like.
[0023]
The balance member 20 accommodated in the internal space 10e of the passage member 10 moves in the left and right directions in the drawing due to the pressure difference received from the contents A and B flowing into the internal space 10e of the passage member 10 on each side surface thereof. Adjustment of the effective inflow cross-sectional area of the inflow ports 10j and 10k is continuously performed.
[0024]
As shown in FIG. 2A, a narrow slit 10i is formed in a communicating portion between the internal space 10e of the passage member 10 and the mixing and discharging space 10h, and the contents A and B pass through the slit. Due to the resistance caused by this, it is easy to mix.
[0025]
In the stationary mode in which the operation member 4 is not pressed, the pressure receiving portion 20c of the balance member 20 is generally located at a substantially central portion of the slit 10i, and the inflow ports 10j and 10k are respectively located inside, as in FIG. It is in a state of communicating with the left portion 10f and the right portion 10g of the space 10e. Since the stems 1a and 2a are not pressed, the contents are not released.
[0026]
When the finger holder 4a of the operating member 4 in FIG. 1 is pressed, the operating member rotates counterclockwise about the shaft 4c as a rotation axis, and the protruding portion 4b becomes the shoulder 10d of the passage member 10 for the contents. And stems 1a and 2a start to move downward.
[0027]
At this time, the lowering state of both stems is seldom the same, and usually, one of the stems moves down ahead of the other. As a result, the pressures of the contents A and B entering the internal space 10e from the inflow ports 10j and 10k to the pressure receiving portion 20c are not balanced.
[0028]
For example, if the pressure from content A is higher than that from content B,
-The pressure receiving portion 20c is pressed rightward in the figure as indicated by the solid arrow,
-The inflow port 10j has its inflow cross-sectional area reduced or closed by the left valve member 20a.
[0029]
Since the contents A sent from the left side portion 10f of the internal space 10e to the mixing / discharging space portion 10h are restricted by the narrow slits 10i, the pressure receiving portion 20c sufficiently receives the pressure of the contents and receives the right pressure in the figure. Move in the direction.
[0030]
On the other hand, since the inlet 10k is still open,
-The content B flows into the right side portion 10g of the internal space 10e,
Pressing the pressure receiving portion 20c leftward in the figure.
[0031]
As described above, the balance member 20 moves in the left-right direction due to the pressure difference between the contents A and B flowing into the internal spaces 10f and 10g from the inflow ports 10j and 10k, and the balance member 20 has a higher pressure (a direction where a larger amount flows into the internal space). 2), the operation of narrowing the effective inflow cross-sectional area of the content distribution inlet is continuously performed, whereby the stable state shown in FIG.
[0032]
Also, when the contents A and B flow into the mixing and discharging space 10h,
A mixing action by moving the pressure receiving portion 20c in the left-right direction;
Resistance due to passing through the narrow slit 10i,
To be mixed.
[0033]
In addition, even when the operation member 30 is pressed in a state where the balance member 20 is not located at the center of the passage member 10, the above-described action occurs due to the pressure difference between the contents A and B flowing into the internal space. The supply ratio of the contents A and B to the section 10h can be made constant.
[0034]
When the balance member 20 moves due to the pressure difference between the contents A and B flowing into the internal space 10e of the passage member 10, the mixing / discharging mechanism α has a high pressure side (for example, a side on which more contents flow). Any structure that reduces the effective inflow cross-sectional area of the inflow port may be used, and the inflow port may not be completely closed.

[0037]
Here, each of the aerosol containers 1 and 2 containing the contents A and B is the same as the mixing and discharging mechanism α in FIG. 1 and will be described with the same reference numerals. The illustration of the comb-like content discharging section, the operation member, and the cover body is omitted.
[0038]
The first feature of the mixed release mechanism β in FIG.
Forming respective detours of the contents A and B flowing into the mixing chamber 52a of the cylindrical member 50,
-Three slits 52d and 52e dedicated to each content are provided at three places to form this detour,
A cross-shaped fine hole 51b was formed at the outlet from the mixing chamber 52a,
That is.
[0039]
As a result, the flow rates and directions of the contents A and B flowing into or out of the mixing chamber 52a are changed, and the contents A and B are in a turbulent state and are surely mixed.
[0040]
A second feature is that the cylindrical member 50 having the above-mentioned mixing action is detachably attached to the respective passage members 41 and 42 of the contents A and B. This makes it possible to easily clean the inside of the tubular member 50 and the passage members 41 and 42 in which the contents A and B are easily solidified.
[0041]
As shown in FIG. 3B, the cylindrical member 50 includes a cylindrical portion 52 having a mixing chamber 52a and an elliptical cylindrical portion 51 having a mixing / discharging space 51a downstream thereof. .
[0042]
A slit 52d for passing the content A and a slit 52e for passing the content B are formed at three places on the outer peripheral surface of the hanging portion 52b of the cylindrical portion 52, respectively.
[0043]
Further, partition plates 52c are provided at two places in such a manner that these slits 52d and 52e are separated from each other. This is because when the contents A and B are mixed, they are easily solidified by a chemical reaction, so that they are prevented from mixing outside of the mixing chamber, or the contents of other containers are prevented from being mixed into the aerosol containers 1 and 2. To do that.
[0044]
Further, a cross-shaped fine hole 51b communicating between the mixing chamber 52a and the contents flowing out from the mixing chamber 52a to the mixing and discharging space 51a is formed.
[0045]
As shown in FIG. 3A, the tubular member 50 is
The outer peripheral surface of the cylindrical portion 52 is in close contact with the inner peripheral surface of the joint 80,
-The hanging part 52b is locked in the groove 80e of the joint 80,
The partition plate 52c abuts the step 80d of the joint 80,
-In the form that the convex part 52f is locked to the step part 80b of the joint 80,
It is attached to a joint 80.
[0046]
At this time,
The slits 52d and 52e of the tubular member 50 are located below the content inflow holes 80g and 80h of the joint 80,
A gap 80f is formed between the outer peripheral surface of the hanging portion 52b of the cylindrical portion 52 and the joint 80,
-A U-shaped detour from the contents inflow holes 80g and 80h of the joint 80 to the mixing chamber 52a of the tubular member 50 is formed through the gap and the slits 52d and 52e.
[0047]
In the operation mode in which the operation member (not shown) is pressed, the contents A and B of the aerosol containers 1 and 2 are the stems 1a and 1b, the contents passages 41a and 41b, the inflow holes 80g and 80h, respectively. The content is discharged from the content discharging portion (not shown) to the external space via the gap 80f, the slits 52d and 52e, the mixing chamber 52a, the cross-shaped fine holes 51b, and the mixing and discharging space 51a.
[0048]
At this time, the contents A and B are respectively
-Flows into the mixing chamber 52a from the upstream side once through the U-shaped bypass described above;
After passing through the circumferential gap 80f, it passes through the three slits 52d and 52e, so that it flows into the mixing chamber 52a in a circulating manner.
As a result, the speed and the direction change, and a turbulent state occurs and the two are mixed.
[0049]
Further, since the cross-shaped fine holes 51b have a shape in which the amount of the contents flowing out from the mixing chamber 52a to the mixing and discharging space 51a is reduced, the contents A and B are added to the above-described detour, and the cross-shaped fine holes 51b are formed. When passing through, they are mixed with each other.
[0050]
Instead of the cross-shaped fine holes 51b, round fine holes may be formed in a form in which the amount of contents flowing out from the mixing chamber 52a to the mixing and discharging space 51a is reduced.
[0051]
When the elliptical tubular portion 51 of the tubular member 50 is rotated in the counterclockwise direction, each of the convex portions 52f is guided by the slope-like portion 80c of the joint 80 and rides on the upper edge portion 80b. 50 can be easily removed from the joint 80, and the mixing chamber 52a and the like can be cleaned.
[0052]
The feature of the mixing / discharging mechanism γ in FIG. 4 is that, in addition to the detours of the contents A and B formed in the mixing / discharging mechanism β in FIG. That is, the narrow gap forming member 70 is provided in the space 61a.
[0053]
The other components of the cylindrical member 60, namely, the convex portion 62f that engages with the step portion 80b of the joint 80, the partition plate 62c provided on the hanging portion 62b of the small-diameter cylindrical portion 62, the slits 62d and 62e are illustrated in FIG. This is the same as the third cylindrical member 50.
[0054]
As shown in FIG. 4 (a), an annular elastic member 72 closely contacting the inner peripheral surface of the cylindrical member 60 is fitted above and below the columnar portion 71 of the narrow gap forming member 70, and vertically below. A groove 71a serving as a passage for the contents is formed. Here, the material of the annular elastic member 72 is, for example, polyethylene, polypropylene, or the like.
[0055]
And, between the annular elastic member and the inner peripheral surface of the large-diameter cylindrical portion 61 of the cylindrical member 60, a passage area for contents whose cross-sectional area gradually decreases as going from the upstream side to the downstream side. 61b are formed.
[0056]
As a result, the contents A and B smoothly flow into the passage area 61b and pass through the narrow gap 61c in a manner of forcibly pressing the annular elastic member 72 inward against the urging force of the annular elastic member 72. Since it is pressed outward by the urging force of the annular elastic member 72, it is stretched thinly and mixed with each other.
[0057]
In the stationary mode in which the operating member (not shown) is not pressed, the annular elastic member 72 comes into close contact with the inner peripheral surface of the large-diameter cylindrical portion 61 due to its urging force, and when the mixing / discharging mechanism γ falls, for example. It has a sealing function to prevent leakage of contents.
[0058]
In the operation mode in which the operating member (not shown) is pressed, similarly to the mixing and discharging mechanism β in FIG. 3, the contents are filled in the internal space 62a of the small-diameter cylindrical portion 62 of the cylindrical member 60 by the detour or the slits 62d and 62e. Is mixed.
[0059]
As shown in FIG. 4 (b), the content in the mixed state passes through the groove 71a and is sent out to the mixing / discharging space 61a. Then, as described above, the contents push the annular elastic member 72 inward and pass through the narrow gap 61b with the inner peripheral surface of the tubular member 60, and at this time, they are in a thinly rolled state and are in a rolled state.

【The invention's effect】
The present invention thus includes an inflow amount adjustment unit that moves in a direction to reduce the content inflow area of the output unit having a larger pressure of the content flowing from each output unit of the plurality of containers into the content passage unit. Since it is provided in the content passage, the supply ratio of the content discharged into the external space can be made constant, and the structure of the mixing and discharging mechanism can be simplified.
[0070]
In addition, a detour is provided between the content passage communicating with each output section of the plurality of containers and the downstream mixing chamber, and pores are formed at the outlet of the mixing chamber. By mixing the object in a turbulent state, the mixing efficiency of the two can be improved.
[0071]
Further, since a narrow passage area is formed in the content common passage portion communicating with each output portion of the plurality of containers, each content can be put into, for example, a rolled state to improve the mixing efficiency of the two.
[0072]
Furthermore, since the narrow passage area setting portion is made of an elastic body biased toward the content passing surface side, each content is effectively rolled by receiving the urging force of the elastic body when passing through the content passing surface. And the mixing efficiency of the two can be improved.
