C 0* The following statement is a full description of this invention, including the best method of performing it known to us: 1A CONTAINER WITH PUMP FOR DISCHARGING BUBBLES This specification claims matter that was disclosed in Australian Patent Application No. 38814/95.

FIELD OF THE INVENTION The present invention relates to a container provided with a pump for discharging bubbles which is capable of bubbling up liquid (for instance, liquid for 10 cleansing foam, liquid for shaving cream and the like) received in a container body to make the liquid flow in a foamy state.

BACKGROUND OF THE INVENTION For instance, the container disclosed in International Publication No. W092/08657 can be exemplified as a container with a pump for discharging bubbles. The container is provided with a container body for receiving liquid having a bubbling property such as a liquid detergent and a pump for discharging bubbles provided on a neck portion of the container body, and they are constructed so that, by depressing a pump head of the pump for discharging bubbles, the liquid is pumped up from the container body and the air is sucked from the outside of 1B the carrier body to mix the liquid and the air. And then, the vapor-liquid mixture is bubbled via a net (bubbling member) provided within the pump and the bubbles are discharged from a nozzle of the pump head.

The pump for discharging bubbles has had various e *e 2 problems as follows.

It sometimes happens that the sucked outside air intrudes into the container body to bubble the liquid, and the liquid surface within the container body is filled with the bubbles, when the bubbles are discharged.

It is difficult to discharge the bubbles in a straight line form relatively for a long range.

A coil spring for energizing the pump head 1 0 upwards all the time is received in a region where it is in contact with the liquid, and the contact of the coil spring with the liquid may be not desirable depending on the kind of the liquid received in the container body, It is not possible to change a discharging form 15 of the bubbles.

There is the possibility that only the air passes through the net (bubbling member) before the liquid passes through the net at the first stage of discharging bubbles, and the bubbles will be discharged unseemly in that case, because the liquid which has remained within the net at the last discharging is formed into larger bubbles by flow of only the air and the large bubbles are discharged from the nozzle of the pump head.

It sometimes happens that the balance of the volumes of the liquid and air to be mixed is lost and the liquid volume becomes smaller than the air volume, 3 and accordingly the bubbling will be incomplete at the first stage of discharging bubbles.

Although the container disclosed Japanese Patent Application No. 6-136411(1994) exists as a container with a pump for discharging bubbles improved in the point of it also leaves room for improvements as follows.

It is difficult to change the size of bubbles i.

(diameter of the bubbles).

A measure for preventing a undesired leakage of liquid which is likely to occur when the container is 0000 overturned and so on is not complete.

It sometimes happens that the bubbles adhered to the net (bubbling member) gets dry to clog the net 15 when it is not used, and the bubbles will be formed badly hereafter.

An object of the present invention is to provide a container with a pump for discharging bubbles in which the liquid is not bubbled before it is bubbled in a bubbling member so that the container body will not be filled with bubbles; a container with a pump for discharging bubbles which is capable of discharging the bubbles in a straight line form relatively for a long range; a container with a pump for discharging bubbles in which a coil spring for energizing a pump head upwards all the time is provided in a position isolated from the liquid; a container with a pump for discharging 4 bubbles which is capable of changing a discharging form of bubbles; a container with a pump for discharging bubble which is capable of discharging bubbles stably in a state that the size of bubbles is fixed from the first stage of discharging bubbles; a container with a pump for discharging bubbles which is capable of changing the diameter of bubbles easily; a container with a pump for discharging bubbles which is capable of preventing an 10 undesirable leakage of liquid and a container with a .0 pump for discharging bubbles in which the net (bubbling member) in not clogged up due to drying.

When the outside cylinder member 110 is rotated relatively to the inside cylinder member 117, although the projection 123b of the inside cylinder member 120 can pass over the passable projection 117 with a predetermined resistance, it can not pass over the stopper projection 116, and 51 accordingly the rotation of the outside cylinder member 110 is limited by the stopper projection 116.

As shown in Fig. 6, when the projection 123b is positioned between the stopper projection 116 and the passable projection 117, the opening l15a of the cylinder portion 115 in the outside cylinder member 110 and the discharging hole 121a of a small diameter in the inside cylinder member 120 are made to communicate with another, and the discharging hole 121b of large 10 diameter is closed by the peripheral surface of the cylinder portion 115.

As shown in Fig. 7, the lower end of 10 the vertical rib 151a tapers off as it proceeds downward Sand the upper end of the engagement projection 124a tapers off as it proceeds upward so that the vertical .rib 151a and the engagement projection 124a are guided by the respective taper surface, when the pump head 100 15 is ascended from the lower part.

In the periphery of the stem 40, an annular flange portion 43 which is projected to the outside is formed near the middle in the vertical direction and an annular rising wall 44 is provided projectingly, upwardly on the upper surface of the flange portion 43. The internal surface of the rising wall 44 is formed on the taper surface whose diameter is enlarged as it proceeds upward.

In the stem 40, the second piston 60 is fitted outwardly to the space between the flange portion 43 and the pump head 100 in a state that it can be moved upward and downward a little. The second piston 60 is formed in 53 a hollow cylinder shape in which the upper and lower ends are opened, the utmost external portion is formed to the seal cylinder portion 61 which slides on the internal surface of the large diameter cylinder portion 22 of the cylinder member 20 air-tightly, the utmost internal portion is formed to the basic cylinder portion 62 which is fitted outwardly to the stem 40 and the seal cylinder portion 61 and the basic cylinder portion 62 are connected with one another by the stepped cylinder 0 portion 63 in which the cross section is bent in a step form.

The upper part of the basic cylinder portion 62 is contacted air-tightly with the internal surface of the cylinder-shaped valve body 125 with pressure in a state that it can be slid. The air hole 64 is provided on the part in which the basic-cylinder portion 62 is connected to the stepped cylinder portion 63 in a state that they are dispersed with respect to the circumferential direction, and the air hole 64 is opened and closed by the relative upward and downward movement between the pump head 100 and the second piston 60. Namely, the air hole 64 is closed when the pump head 100 moves upward and downward relatively to the second piston 60 so that the cylinder-shaped valve body 125 of the pump head comes into contact with the part where the basic cylinder portion 62 is connected to the stepped cylinder portion 63, and the air hole 64 is opened when the 54 cylinder-shaped valve body 125 is separated from the above-mentioned connection part.

'The lower end of the basic cylinder portion 6 2 is brought into contact with and separated from the internal surface of the rising wall 44 of the stem 40 by the relative upward and downward movement between the stem 40 and the second piston 60. In the external surface of the stem 40, a plurality of verticai grooves which are extended in the vertical direction are provided in a region to.which the basic cylinder portion 62 is fitted outwardly in a state that they are dispersed with respect to the circumferential direction.

A second air Suction valve 90 is fixed on the lower part of the basic cylinder portion 62. The second air suction valve 90 is provided with an annular diaphragm 91 of upward taper which is extended outside in the diametral direction from the lower end thereof. The diaphragm 91 has an elasticity, and operates so that the peripheral end portion of the diaphragm 91 is brought 55 into contact with the lower surface of the stepped cylinder portion 63 of the second piston 60 with pressure to be sealed under normal conditions, and the peripheral edge of the diaphragm 91 is pulled downward by negative pressure within the large-diameter cylinder portion 22 to be separated from the stepped cylinder portion 63.

In the attaching trunk 150, a cylinder-shaped rib 152 is provided on the outside of the central cylinder 10 portion 151, and the first air suction valve 80 which seals the space between the attaching trunk 150 and the internal surface of the large-diameter cylinderportion 22 is fixed on the lower end of the cylinder-shaped rib 152. A seal cylinder portion 81 of the first air 15 suction valve 80 in contact with the large-diameter cylinder portion 22 is formed in a taper cylinder shape to be extended in the diagonal upper direction, and has o an elasticity. Besides, the upper end portion of the seal cylinder portion 81 operates so that it is pulled inside in the diametral direction by negative pressure within the container body 1 to be separated from the internal surface of the large-diameter cylinder portion 22.

Further, a clear cover 202 is detachably provided on the attaching trunk 150.

Then, the operation of the container with a pump for discharging bubbles of the embodiment 1 will be 56 described.

Fig. 1 and Fig. 3 indicate a state that the pump head is ndt yet depressed, namely, a state that the pump head is positioned at the upper limit. In this state, the liquid suction valve 30 is pushed up through the first piston 50 by the coil spring 39, the lower-part valve body 31 is separated from the valve seat 24a of the cylinder member 20, and the inside of the smalla diameter cylinder portion 24 is made to communicate with 10 the inside of the container body 1 through the suction pipe 201. The upper-part valve body 35 of the liquid suction valve 30 is in contact with the valve seat of the first piston 50 to close the upper-part opening of the first piston 50. The lower end of the basic 15 cylinder portion 62 of the second piston 60 is in S"contact with the rising wall 44 of the stem 40, the first air suction valve 80 is in contact with the stepped cylinder portion 63 of the second piston 60 and the large-diameter cylinder portion 22 of the cylinder member 20 with pressure, and the lower end of the cylinder-shaped valve body 125 of the pump head 100 is separated from the stepped cylinder portion 63 of the second piston 60 to open the air hole 64.

As the pump head 100 is depressed from the abovementioned state, the stem 40 and the first piston 50 are descended together with the pump head 100. As a result, as shown in Fig. 4, the upper-part valve body 35 of the 57 liquid suction valve 30 is separated from the valve seat 52 of the first piston 50 to open the upper-part opening of the fist piston 50. At almost the same time, the inside of the small-diameter cylinder portion 24.is pressurized by descending the first piston 50, the liquid suction valve 30 is descended by liquid pressure within the small-diameter cylinder portion 24, and the lower-part valve body 31 comes into contact with the valve seat 24a to close the lower part opening of the 10 small diameter cylinder portion 24. On the other hand, the second piston 60 is standing by frictional force between the seal cylinder portion 61 and the largediameter cylinder portion 22 right after the depressing of the pump head has started. As a result of descending 15 of the stem 40 in the state, the lower end of the basic cylinder portion 62 of the second piston 60 is separated from the rising projection 44 of the stem 40, and the lower end of the cylinder-shaped valve body 125 of the pump head 100 comes into contact with the stepped cylinder portion 63 of the second piston 60 to close the air hole 64.

The second piston 60 is also descended together with the pump head 100, the, stem 40 and the first piston after the lower end of the cylinder-shaped valve body 125 of the pump head 100 comes into contact with the stepped cylinder portion 63 of the second piston As the pump head 100 is descended after that, the 58 liquid within the small-diameter cylinder portion 24 pressurized by the first piston 30 passes through the upper end opening of the first piston-30 and the vertical grooves 33a and 34a of the liquid suction valve 30 and passes through the space between the vertical ribs 42 of the stem 40 to be pushed into the upper-part of the upper part valve body 35. Further, the liquid pushes up the liquid discharge valve 70 with hydraulic S" pressure to flow into the vapor-liquid mixing chamber 46 (See Fig. On the other hand, the air received within the large diameter cylinder portion 22 passes through the space between the flange portion 43 and rising projection 44 of the stem 40 and the lower end of the basic cylinder portion 62 of the second piston 15 passes through the vertical groove 45 of the stem passes through the vertical groove 123a of the inside cylinder member 120 of the pump head 100, and passes through the passage between the casing 131 of the bubbling unit 130 and the stem 40 to flow into the vapor-liquid mixing chamber 46.

Then, the liquid and the air are joined and mixed in the vapor-liquid mixing chamber 46 to be delivered into the bubbling unit 130.. After that, the liquid is bubbled when it passes through the upper and lower two nets 133 of the bubbling unit 130 to be pushed into the cylinder portion 115 of the pump head 100 in a foamy state. The bubble passes through the opening 115a of 59 the cylinder portion 115 and the small-diameter discharging hole 121a of the small-diameter cylinder member 120 to be discharged from the ~kozzle 113 of the pump head 100. Fig. 8 indicates a discharging state of the bubbles at the moment, and the bubbles are discharged strongly in a state that they are converged finely.

When the outside cylinder member 110 is rotated at 180 degrees against the inside cylinder member 120, the 0 opening 115a of the cylinder portion 115 in the outside cylinder member 110 is made to communicate with the large-diameter discharging hole 121b of the inside cylinder member 120 before depressing the pump head 100, and the pump head 100 is depressed in the state, the 15 thick bubbles are discharged from the nozzle 113, as •9 shown in Fig. 9. The strength of the bubbles discharged at this case is weaker than that of the bubbles discharged through the small-diameter discharging hole 121a.

Namely, in the container with a pump for discharging bubbles, it is possible to select one of the large and small discharging holes 121a and 121b to let the bubbles pass through the discharging hole so as to change the discharging form of the bubbles, if relative position in the circumferential direction of the outside cylinder member 110 and the inside cylinder member 12 of the pump head 100 is selected according to 60 circumstances.

If the finger is off from the pump head 100 after the depressing of the pump head 100, the hydraulic pressure within the small-diameter cylinder portion 24 and the air pressure within the large-diameter cylinder portion 22 falls, the liquid discharge valve 70 is brought into contact with the valve seat 41, and the first piston 50, stem 40 and the pump head 100 are pushed up by the elasticity of the coil spring 39.

10 Hereupon, the second piston 60 is standing by frictional force between the seal cylinder portion 61 and the large-diameter cylinder portion 22 right after the pushing up of the pump head has begun. As a result of ascending of the stem 40 in the state, the internal 15 surface of the rising projection 44 of the stem 40 is brought into contact with the lower end of the basic cylinder portion 62 of the second piston 60 with pressure to close the space between the inside of the large-diameter cylinder portion 22 and the vertical groove 45 of the stem 40. At the same time, the lower end of the cylinder-shaped valve body 125 of the pump head 100 is separated from the stepped cylinder portion 63 of the second piston 60 to open the air hole 64.

The first piston 50, the stem 40, the second piston 60 and the pump head 100 are ascended together, after the internal surface of the rising projection 44 comes into contact with the lower end of the basic cylinder 61 portion 62.

The inside of the small-diameter cylinder potion 24 is pressurized negatively when the first piston 5L is ascended, and accordingly the liquid suction valve 30 is pulled up and the lower-part valve body 31 is separated from the valve seat 24a to make the inside of the small diameter cylinder portion 24 communicate with the inside of the container body 1. As a result, the liquid within the container body 1 is sucked up into the smalldiameter cylinder portion 24, as the first piston 50 is 4ascended.

The inside of the container body 1 is pressurized negatively when the liquid is pumped up into the small- S- diameter cylinder portion 24, and accordingly the seal 15 cylinder portion 81 of the first air suction valve 80 is drawn to the direction away from the internal surface of the large diameter cylinder portion 22, and a gap is 4. generated between the seal cylinder portion 81 and the large diameter cylinder portion 22.

Besides, the inside of the large-diameter cylinder portion 22 is pressurized negatively as the second piston 60 is ascended, and accordingly the diaphragm 91 of the second air suction valve 90 is drawn downward and separated from the stepped cylinder portion 63 of the second piston 60 to generate a gap.

As a result of operating of the first air suction valve 80 and the second air suction valve 90 in the 62 above-mentioned way, the outside air is sucked into the attaching trunk 150 through the space between the central cylinder portion 151 of the attaching trunk 150 and the pump head 100. Then, part of the air passes through the air hole 64 of the second piston 60 to get into the large-diameter cylinder portion 22, and the other air passes through the flange portion 21 of the cylinder member 20 to get into the container body 1. By these actions, the pressures within the large-diameter .10 cylinder portion 22 and the container body 1 are equal to the air pressure, the first piston 50 and the second piston 60 are ascended smoothly and the liquid is pumped Sup into the small-diameter cylinder portion 24 smoothly.

The container with a pump for discharging bubbles 15 is in a initial state shown in Fig. 1 and Fig. 3, when the pump head 100 returns to the upper limit.

[THE EMBODIMENT 2] The container with a pump for discharging bubbles of the embodiment 2 will be described in accordance with Fig. 10 and Fig. 11.

The basic constructions of the container with a pump for discharging bubbles of the embodiment 2 is the same as those of the embodiment 1, and the difference lies in a part of the construction of the pump head 100.

In the pump head 100 in the embodiment 2, the outside cylinder member 110 can be held in a position 63 where the opening 115a of the outside cylinder member 110 is closed without being connected to any one of the discharging holes 121a and 121b of the inside cylinder member 120.

The construction will be described. Fig. 10 and Fig. 11 are cross section diagrams corresponding to Fig.

and Fig. 6 of the embodiment 1. As shown in Fig. 11, in the internal surface of the peripheral wall portion *eeo 111 of the outside cylinder member 110, a pair of iO passable projections 118a and 118b in addition to the stopper projection 116 andpassable projection 117 are provided in a position separated at 180 degrees in the circumferential direction one another.

When the projection 123b of the inside cylinder member 120 is positioned in a space between the passable projection 118a and the passable projection 118b, the opening 115a of the cylinder portion 115 of the outside cylinder member 110 is closed by the internal surface of the small-diameter portion 121 of the inside cylinder member 120 without being made to communicate with any one of the discharging holes 121a and 121b of the inside cylinder member 120, and the discharging holes 121a and 121b are closed by the external surface of the cylinder portion 115 at the same time, as shown in Fig. If the opening 115a is closed in the abovementioned way, the inside of the inside cylinder member 120 can be prevented from getting dry. Although it 64 sometimes happens that part of the bubbles are solidified in a state that it is adhered to the net 133, the meshes of the net 133 are clogged and the formation of the bubbles is insufficient or unstable when the pump is operated after that, if the inside cylinder member 120 gets dry, in the embodiment 2, it is possible to prevent the bubbles within the pump head 100 from getting dry, and accordingly a clogging of the net 133 as a bubbling member can be prevented and the bubbles S 10 can be formed well and stably.

Further, if the outside cylinder member 110 is rotated against the inside cylinder member 120 in the state of Fig. 10 and Fig. 11, the project 123b can pass over the passable projection 118a or the passable 15 projection 118b, and accordingly the opening 115a can be made to communicate with-the discharging hole 121a or the discharging hole 121b.

[THE EMBODIMENT 3] The container with a pump for discharging bubbles of the embodiment 3 will be described in accordance with Fig. 12 to Fig. Fig. 12 is a longitudinal section diagram of the container with a pump for discharging bubbles of the embodiment 3. The difference between the embodiment 3 and the embodiment 1 lies in the pump head 100, and other constructions of the embodiment 3 are the same as 65 those of the embodiment 1. Only the difference will be described below, and the descriptions concerning the constructions which are the same as those of the container with a pump for discharging bubbles of the embodiment 1 will be omitted by giving the identical numbers to the same conditional parts.

Fig. 20 is a cross section diagram of the cylinder portion 115 of the outside cylinder member 110 and the small-diameter portion 121 of the inside cylinder member 120, and Fig. 21 is a cross section diagram of the large-diameter portion of the stepped hole of the outside cylinder member 110 and the large-diameter portion 123 of the inside cylinder member 120.' As shown in Fig. 21, in the internal surface of the o 10 large-diameter portion of the stepped hole of the outside cylinder member 110, sets of stopper projection' 116 and passable projection 117 which are extended in the vertical direction are formed in positions which are separated at 180 degrees one another in the 15 circumferential direction. On the other hand, on the external surface of the large-diameter portion 123 of the inside cylinder member 120, the projections 123b which are extended in the vertical direction are each formed on the positions which are separated at 180 degrees one another in the circumferential direction.

When the outside cylinder member 110 is rotated relatively to the inside cylinder member 120, although the projection 123b can pass over the passable projection 117 with a predetermined resistance, it can not pass over the stopper projection 116, and accordingly the rotation of the outside cylinder member 110-is limited by the stopper projection 116.

78 As shown in Fig. 21, when the projection 123b is positioned between the stopper projection 116 and the passable projection 117, the peripheral surface of the cylinder portion 115 closes the discharging hole 121b and the peripheral surface of the small-diameter portion 121 closes the opening 115a of the cylinder portion 115.

Then, the opening 115a of the cylinder portion 115 is made to communicate with the discharging hole 121b, and the nozzle 113 is positioned in front of the discharging 10 nozzle 121b in a state that the outside cylinder member 110 is rotated against the inside cylinder member 120, and the projection 123b is made to pass over the passable projection 117 to be stopped on the other stopper projection 117 which is separated at 180 15 degrees.

A large number of vertical ribs 151a which are extended in the vertical direction are formed on the internal surface of the central cylinder portion 151, and a large number of engagement projections 124a which are each inserted between the vertical ribs 151a are formed on 79 the lower end of the external surface of the skirt cylinder portion 124 in a state that they are projected to the outside. As shown in Fig. 22, the lower end of the vertical rib 151a tapers off as it proceeds downward, and the upper end of the engagement projection 124a tapers off as it proceeds upward so that the vertical rib 151a and the engagement projection 124a will be guided by the respective taper surface, when the pump head 100 is ascended from the lower position.

In the periphery of the stem 40, the annular flange portion 43 which is projected to the outside is formed near the middle in the vertical direction, and an annular rising wall 44 is provided projectingly, upwardly on the upper surface of the flange portion 43.

Namely, the air hole 64 is closed S• when the pump head 100 moved upward and downward relatively to the second piston 60 so that the cylindershaped valve body 125 of the pump head 100 comes into contact with the part where the basic cylinder portion 62 is connected to the stepped cylinder portion 63, and the air hole 64 is opened when the cylinder-shaped valve body 125 is separated from the above-mentioned connection part.

The lower end of the basic cylinder portion 62 is brought into contact with and separated from the internal surface of the rising wall 44 of the stem 40 by 81 the relative upward and downward movement between the stem 40 and the second piston 60. In the external surface of the stem 40, a plurality of vertical grooves which are extended in the vertical direction are provided on the region to which the basic cylinder portion 62 is fitted outwardly in a state that they are dispersed with respect to the circumferential direction.

a The second air suction valve 90 is fixed on the lower part of the basic cylinder portion 62. The second air suction valve 90 is provided with an annular diaphragm 91 of upward taper which is extended to the outside in the diametral direction from the lower end thereof. The diaphragm 91 has an elasticity and operates so that the peripheral end portion of the diaphragm 91 comes into contact with the lower surface of the stepped cylinder portion 63 of the second piston 60 to be sealed under normal conditions, and the peripheral end of the diaphragm 91 is pulled downward by negative pressurization within the large diameter 82 cylinder portion 22 to be separated from the stepped cylinder portion 63.

In the attaching trunk 150, the cylinder-shaped rib 152 is provided on the outside of the central cylinder portion 151, and the first air suction valve 80 for sealing the space between the attaching trunk 150 and the internal surface of the large-diameter cylinder portion 22, is fixed on the lower end of the cylindershaped rib 152. A seal cylinder portion 81 of the first 10 suction valve 80 in contact with the large- diameter cylinder portion 22 is formed in a taper cylinder shape to be extended in the diagonal upper direction and has an elasticity, and the upper end portion of the seal cylinder portion 81 operates so that it is pulled inside 15 in the diametral direction by negative pressurization within the container body 1, to be separated from the internal surface of the large- diameter cylinder portion 22.

Further, the clear cover 202 is detachably provided on the attaching trunk 150.

Then, the operation of the container with a pump for discharging bubbles of the embodiment 4 will be described.

Fig. 16 and Fig. 18 indicate a state that the pump head is not yet depressed, namely, a state that the pump head 100 is positioned at the upper limit. Besides, Fig. 16 indicates a state that the discharging hole 121b 83 of the inside cylinder member 120 in the pump head 100 is closed.

When the bubbles-are discharged, first of all, the cover 202 is removed and the outside cylinder member 110 is rotated against the inside cylinder member 120 so as to make the discharging hole 121b of the inside cylinder member 120 communicate with the opening 115a of the outside cylinder member 110.

In a state that the pump head 100 is not yet depressed, the liquid suction valve 30 is pushed up by the coil spring 39 through the first piston 50, the lower-part valve body 31 is separated from the valve seat 24a of the cylinder member 20, and the inside of the small-diameter cylinder portion 24 is made to communicate with the inside of the container body 1 through the suction pipe 201. The upper-part valve body 35 of the liquid suction valve 30 is in contact with the valve seat 52 of the first piston 50 to close the upper part opening of the first piston 50. The lower end of the basic cylinder portion 62 of the second piston 60 is in contact with the rising wall 44 of the stem 40, the first air suction valve 80 is in contact with the stepped cylinder portion 63 of the second piston 60 and the large-diameter cylinder portion 22 of the cylinder member 20 with pressure, and the lower end of the cylinder-shaped valve body 125 of the pump head 100 is separated from the stepped cylinder portion 63 of the 84 second piston 60 to open the air hole 64.

As the pump head 100 is depressed from that state, the stem 40 and the first piston 50- are descended together with the pump head 100. As a result, as shown in Fig. 19, the upper-part valve body 35 of the liquid suction valve 30 is separated from the valve seat 52 of the first piston 50 to open the upper-part opening of the first piston 50. At almost the same time,- the inside of the small-diameter cylinder portion 24 is 10 pressurized by descending of the first piston 50, the liquid suction valve 30 is descended by the hydraulic pressure within the small-diameter cylinder portion 24 and the lower-part valve body 31 comes into contact with the valve seat 24a to close the lower-part opening of o 15 the small diameter cylinder portion 24. On the other hand, the second piston 60 is standing by the frictional force between the seal cylinder portion 61 and the large-diameter cylinder portion 22 right after the depressing of the pump head has been started. As a result of descending of the stem 40 in the state, the lower end of the basic cylinder portion 62 of the second piston 60 is separated from the rising projection 44 of the stem 40, and the lower end of the cylinder-shaped valve body 125 of the pump head 100 comes into contact with the stepped cylinder portion 63 of the second piston 60 to close the air hole 64.

The second piston 60 is also descended together 85 with the pump head 100, the stem 40 and the first piston after the lower end of the cylinder-shaped valve body 125 of the pump head 100 comes into contact with the stepped cylinder portion 63 of the second piston As the pump head 100 is descended after that, the liquid within the small-diameter cylinder portion 24 pressurized by the first piston 30 passes through the upper-end opening of the first piston 30 and the vertical grooves 33a and 34a of the liquid suction valve 30, and passes through the space between the vertical ribs 42 of the stem 40 to be pushed into the upper-part of the upper part valve body 35. Further the liquid pushes up the liquid discharge valve 70 with the hydraulic pressure to flow into the vapor-liquid mixing 15 chamber 46 (See Fig. 17). On the other hand, the air received within the large-diameter cylinder portion 22 passes through the space between the flange portion 43 and the rising projection 44 of the stem 40 and the lower end of the basic cylinder portion 62 in the second piston 60, passes through the vertical groove 45 of the stem 40 and passes through the vertical groove 123a of the inside cylinder member 120 in the pump head 100.

Further, the air passes through the passage between the casing 131 of the bubbling unit 130 and the stem 40 to flow into the vapor-liquid mixing chamber 46.

Then, the liquid and the air are joined and mixed within the vapor-liquid mixing chamber 46 to be 86 delivered into the bubbling unit 130. After that, the liquid is bubbled when it passes through two upper and lower nets 133 of the bubbling unit 130 to.be puzhed into the cylinder portion 115 of the pump head 100 in a foamy state. The bubbles pass through the opening 115a of the cylinder portion 115 and the discharging hole 121b of the small-diameter portion 121 to be discharged from the nozzle 113 of the pump head 100. Fig% 23 indicates a discharging state of the bubbles at the time.

If the finger is off from the pump head 100 after the depressing of the pump head 100, the hydraulic pressure within the small-diameter cylinder portion 24 and the air pressure within the large-diameter cylinder 15 portion 22 fall, the liquid discharge valve comes into contact with the valve seat 41, and the first piston the stem 40 and the pump head 100 are pushed up by the elasticity of the coil spring 39.

Hereupon, the second piston 60 is standing by the frictional force between the seal cylinder portion 61 and large-diameter cylinder portion 22 right after the pushing up of the stem 40 has begun. As a result of ascending of the stem 40 in the state, the internal surface of the rising projection 44 of the stem 40 comes in contact with the lower end of the basic cylinder portion 62 of the second piston 60 with pressure to close the space between the inside of the bid diameter 87 cylinder portion 22 and the vertical groove 45 of the stem 40. At the same time, the lower end of the cylinder-shaped valve body 125 of the pump head 100 is separated from the stepped cylinder portion 63 of the second piston 60 to open the air hole 64.

The first piston 50, the stem 40, the second piston 69 and the pump head 100 are ascended together after the internal surface of the rising projection 44 comes into contact with the lower end of the basic cylinder 10 portion 62.

The inside of the small-diameter cylinder portion 24 is pressurized negatively when the first piston 50 is ascended, and accordingly the liquid suction valve 30 is pulled up and the lower part valve body 31 is separated 15 from the valve seat 24a so as to make the inside of the small diameter cylinder portion 24 communicate with the inside of the container body 1. As a result, the liquid within the container body 1 is sucked up into the small diameter cylinder portion 24 as the first piston 50 is ascended.

The inside of the container body 1 is pressurized negatively when the liquid is pumped up into smalldiameter cylinder, and accordingly the seal cylinder portion 81 of the first air suction valve 80 is drawn to the direction away from the internal surface of the large-diameter cylinder portion 22, and the gap is generated between the seal cylinder portion 81 and the 88 large-diameter cylinder portion 22.

Besides, the inside of the large-diameter cylinder portion 22 is also pressurized negatively as the second piston 60 is ascended, and accordingly the diaphragm 91 of the second air suction valve 90 is drawn downward and separated from the stepped cylinder portion 63 of the second piston 60 so as to generate the gap.

As a result of operating of the first air, suction valve 80 and the second air suction valve 90 in the S: 10 above-mentioned way, the outside air is sucked into the attaching trunk 150 from the space between the central cylinder portion 151 of the attaching trunk 150 and the •pump head 100. Then, part of the air passes through the air hole 64 of the second piston 60 to get into the 15 large-diameter cylinder portion 22, and the other air S• passes through the air hole 27 of the flange portion 21 in the cylinder member 20 to get into the container body 1. Accordingly, the pressures within the large-diameter cylinder portion 22 and the container body 1 are equal to the air pressure, the first piston 50 and the second piston 60 are ascended smoothly, and the liquid is pumped up into the small diameter cylinder portion 24 smoothly.

When the container is in a state that it is not used after returning the pump head 100 to the upper limit position, the outside cylinder member 110 of the pump head 100 is rotated against the inside cylinder 89 member 120, the discharging hole 121b of the inside cylinder member 120 is closed by the cylinder portion 115 of the outside cylinder member 110, and the opening 115a of the cylinder portion 115 is closed by the smalldiameter portion 121 of the inside cylinder member 120.

At that time, the projection 123b of the outside cylinder member 110 passes over the passable projection 117 of the inside cylinder member 120 to come into contact with the stopper projection 116.

O* C As mentioned hereinbefore, if the opening 115a and the discharging hole 121b are closed, the inside of the pump for discharging bubbles 10 can be prevented from *0 C getting dry, and the bubbles which are not discharged and are remaining within the pump for discharging bubbles 10 do not get dry to be solidified.

Accordingly, the bubbles adhered to the net 133 of the bubbling unit 130 do not get dry to be solidified, and the net 133 is not be clogged. As a result, the bubbles can be formed securely and stably even when the bubbles are discharged for the next time.

Then, the operation of the container with a pump for discharging bubbles in the embodiment 7 will be described.

Fig. 35 and Fig. 37 indicate a state that the pump head 100 is not yet depressed, namely, a state that the pump head is positioned at the upper limit. First of all, the cover 202 is removed when the bubbles are discharged.

In the state that the pump head is not yet depressed, the liquid suction valve 30 is pushed up by the coil spring 39 through the first piston 50, the 107 lower-part valve body 31 is separated from the valve seat 24a of the cylinder member 20, and the inside of the small diameter cylinder portion 24 l hiade to communicate with the inside of the container body 1 through the suction pipe 201. The upper-part valve body of the liquid suction valve 30 is in contact with the valve seat 52 of the first piston 50 to close the upperpart opening of the first piston 50. The lower end of the basic cylinder portion 62 of the second piston 60 is 10 attached to the rising wall 44 of the stem 40, the first air suction valve 80 is in contact with the stepped cylinder portion 63 of the second piston 60 and the large-diameter cylinder portion 22 of the cylinder member 20 with pressure, and the lower end of the 15 cylinder-shaped valve body 102b of the pump head 100 is separated from the stepped cylinder portion 63 of the second piston 60 to open the air hole 64.

If the pump head 100 is depressed in the abovementioned state, the stem 40 and the first piston will be descended together with the pump head 100. As a result, as shown in Fig. 38, the upper part valve body of the liquid suction valve 30 is separated from the valve seat 52 of the first piston 50 to open the upperpart opening of the first piston 50. At almost the same time, the inside of the small-diameter cylinder portion 24 is pressurized by descending of the first piston the liquid suction valve 30 is descended by the 108 hydraulic pressure within the small-diameter cylinder portion 24, and the lower-part valve body 31 comes into contact with the valve seat 24a to alose the lower-part opening of the small diameter cylinder portion 24. On the other hand, the second piston 60 is standing by the frictional force between the seal cylinder portion 61 and the large-diameter cylinder portion 22 right after the depressing of the pump head 100 has been started.

As a result of descending the stem 40 in the state, the 1 0 lower end of the basic cylinder portion 62 of the second piston 60 is separated from the rising projection 44 of the stem 40, and the lower end of the cylinder-shaped valve body 102b of the pump head 100 comes into contact with the stepped cylinder portion 63 of the second piston 60 to close the air hole 64.

The second piston 60 is descended together with the pump head 100, the stem 40 and the first piston after the lower end of the cylinder-shaped valve body 102b of the pump head 100 comes into contact with the stepped cylinder portion 63 of the second piston If the pump head 100 is descended after that, the liquid within the small-diameter portion 24 pressurized by the first piston 30 passes through the upper-part opening of first piston 30 and the vertical grooves 33a and 34a of the liquid suction valve 30 and passes through the space between the vertical ribs 42 of the stem 40 to be pushed out to the upper-part of the upper 109 part valve body 35, and pushes up the liquid discharge valve 70 with the hydraulic pressure from the valve seat 41 to flow into the vapor-liquid mixing chamber 46 (-See Fig. 36). On the other hand, the air received within the large-diameter cylinder portion 22 passes through the space between the flange portion 43 and rising projection 44 of the stem 40 and the lower end of the basic cylinder portion 62 in the second piston' passes through the vertical groove 45 of the stem 10 passes through the vertical groove 102a of the inside cylinder portion 102 in the pump head 100, and passes through the passage between the casing 131 of the bubbling unit 130 and the stem 40 to flow into the vapor-liquid mixing chamber 46.

Then, the liquid and air are joined and mixed in the vapor-liquid mixing chamber to be delivered into the bubbling unit 130. After that, the liquid is bubbled .when it passes through the upper and lower two nets 133 of the bubbling unit 130 and the bubbled liquid is pushed into the bubble passage 105 of the pump head 100 to be discharged from the nozzle 104 of the pump head 100. Fig. 40 indicates a discharging state of the bubbles at this time.

When the finger is off from the pump head 100 after the depressing of the pump head 100 has been completed, the hydraulic pressure within the small-diameter cylinder portion 24 and the air pressure within the 110 large-diameter cylinder portion 22 fall, the liquid discharge valve 70 comes into contact with to the valve seat 41, and the first piston 50, the stem 40 and the pump head 100 is pushed upward by the elasticity of the coil spring 39.

Hereupon, the second piston 60 is standing by the frictional force between the seal cylinder portion 61 and the large-diameter cylinder portion 22 right after :the pushing up of the stem 40 has begun. As a result of ascending the stem 40 in the state, the internal surface of the rising projection 44 of the stem 40 comes into contact with the lower end of the basic cylinder portion 62 of the second piston 60 with pressure, and the space between the inside of the large-diameter cylinder portion 22 and the vertical groove 45 of the stem 40 is shut off. At the same time, the lower end of the cylinder-shaped valve body 102b of the pump head 100 is separated from the stepped cylinder portion 63 of the second piston 60 to open the air hole 64.

The first piston 50, the stem 40, the second piston and the pump head 100 are ascended together after the internal surface of the rising projection 44 comes into contact with the lower end of the basic cylinder portion 62.

The inside of the small diameter cylinder portion 24 is pressurized negatively when the first piston 50 is ascended, and accordingly the liquid suction valve 30 is 111 pulled up, the lower-part valve body 31 is separated from the valve seat 24a, and the inside of the smalldiameter cylinder portion 24 is made to communicate with the inside of the container body 1. As a result, the liquid within the container body 1 is sucked up into the small-diameter cylinder portion 24 as the first piston 50 is ascended.

The inside of the container body 1 is pressurized negatively when the liquid is pumped up into the small- 10 diameter cylinder portion 24, and accordingly the seal cylinder portion 81 of the first air suction valve 80 is drawn in the direction away from the internal surface of the large-diameter cylinder portion 22.

Besides, the inside of the large-diameter cylinder portion 22 is also pressurized negatively as the second piston 60 is ascended, and accordingly the diaphragm 91 of the second air suction valve 90 is drawn downward to be separated from the stepped cylinder portion 63 of the second piston 60, and the gap is generated.

As a result of operating of the first air suction valve 80 and the second air suction valve 90 in the above-mentioned way, the outside air is sucked into the attaching trunk 150 from the space between the central cylinder portion 151 of the attaching trunk 150 and the pump head 100. Then, part of the air passes through the air hole 64 of the second piston 60 to get into the large-diameter cylinder portion 22, and the other air 112 passes through the air hole 27 of the flange portion 21 in the cylinder member 20 to get into the container body 1. Accordingly, the pressures within the laryedim.eter portion 22 and the container body 1 are equal to the air pressure, the first piston 50 and the second piston are ascended smoothly, and the liquid is pumped up into the small-diameter cylinder portion 24 smoothly.

As mentioned hereinbefore, when the finger is off from the pump head 100 after the depressing of the pump o' 10 head 100 has been completed, the hydraulic pressure within the small-diameter cylinder portion 24 falls, and the liquid discharge valve 70 separated upward from the valve seat 41 is descended to be brought into contact with the valve seat 41 so as to close the liquid entrance of the vapor-liquid mixing chamber 46.

S" It takes a little time to bring the liquid discharge valve 70 into contact with the valve.seat 41 so as to close the liquid entrance, and the liquid and air within the vapor-liquid mixing chamber 46 flow into the stem 40 positioned in a portion lower than the valve seat 41 in the meantime. The air which has flown into the stem 40 at this moment may have a bad effect upon the pump for discharging bubbles 10 such as deteriorating the pump efficiency for the liquid and generating large bubbles at the beginning of discharging bubbles, when the bubbles are discharged for the next time.

113 However, in this pump for discharging bubbles since the maximum movement range of the liquid discharge -valve 70 from the state that it is in contact with the valve seat 41 to the state that it is moved to the vertical upper direction is limited within the range of from 0.1 mm to 1.0 mm by the small- diameter portion 131b of the bubbling unit 130, the time required for bringing the liquid discharge valve 70 separated from the valve seat into contact with the valve seat 41 is 10 reduced extremely, and the liquid entrance of the vaporliquid mixing chamber 46 can be closed in a moment.

Accordingly, the air that flows backward into the stem from the vapor-liquid mixing chamber 46 can be removed almost completely.

As a result, the pump efficiency for the liquid is improved, and as shown in Fig. 40, the small bubbles are generated from the beginning of discharging without generating the large bubbles.

Further, it has been confirmed that the particularly preferred result can be obtained and the effect is remarkable, if the vertical movement range from the state that the liquid discharge valve 70 is in contact with the valve seat.41 to the state that the liquid discharge valve 70 comes into contact with the small diameter portion 131b of the bubbling unit 130 is within the range of 0.2 mm 0.3 mm.

A dual seal structure is formed by the seal cylinder portions 81 and 82 Further, it is preferable that each of the members is formed from synthetic resin, elastomer and the like.

Then, the operation of the embodiment 8 will be °o° 10 described.

When the pump head 100 is depressed, the lower part valve body 31 is closed to pressurize the inside of the small diameter cylinder portion 24, and the liquid within the small-diameter cylinder portion 24 pushes up S" 15 the liquid discharge valve 70 to be introduced into the bubble passage 105. At the same time, the air *oe: pressurizing chamber A is pressurized and the second piston 60 is ascended relatively to the stem 40 to open the seal of the lower end of the basic cylinder portion 62, the pressurized air within the air pressurizing chamber A passes through the air passage 102c to be introduced into the bubble passage 105, and the vaporliquid mixed solution which.has been mixed hereupon passes through the bubbling unit 130 to be bubbled, then passes through the unit for regulating bubbles 139 to be discharged from the end of the nozzle 107 in a foamy state.

127 Then, when the pump head 100 is released from the depressing, the stem 40 and the pump head 100 are ascended by the action of the coil spring 39 and- the inside of the small-diameter cylinder portion 24 is pressurized negatively, and accordingly the liquid discharge valve 70 is closed, the suction valve 55 is opened, and the liquid within the container body 2 is sucked into the small diameter cylinder portion 24. On the other hand, the second piston 60 is descended e*0 relatively to the stem 40 to seal the lower end of the basic cylinder. portion 62 and close the air passage 102c, and the outside air is introduced into the air pressurizing chamber A which has been pressurized negatively through the second air suction valve oe At the same time, the first air suction valve 80 is opened and the outside air is introduced into the "container body 1 from the air hole 27, since the inside of the container body 1 is pressurized negatively due to the fact that the liquid within the container body 1 is sucked into the small diameter cylinder portion 24.

The air exists all the time in the air hole 27 portion and the portion is never submerged in the liquid, because the opening.of the nozzle 107 and the opening of the suction pipe 201 are in the same direction all the time, and the air hole 27 is in a position opposite to the opening direction of the nozzle 107, when the bubbles are discharged.

128 Accordingly, the introduced outside air never gets to the liquid surface through the inside of the liquid.

As a result, the inconvenience that the upper part of the liquid surface is filled with the bubbles and so on will never occur.

The liquid within the container body 1 can be discharged entirely, because the lower end opening of the suction pipe 201 is directed to the same direction as the opening direction of the nozzle 107 and is *o 10 positioned in the lower end portion within the container body 1.

Further, 172 the bubbles of large-diameter could be bubbled when only one bubbling element 132 in which the net 133 was provided extendedly on the upper end of the short cylinder 83 was fitted to the upper part of the casing 131.

In the pump for discharging bubbles 10, the 10 discharged bubbles can be accelerated in the conical cylinder shaped wall 501 to be discharged off at a relatively long distance in a linear shape, because the mouthpiece 500 for injection is provided on the end of the nozzle 107. Accordingly, the diversified use for 15 the container with a pump for discharging bubbles of ooaoo. late years is matched up, and the demand can be met S..sufficiently.

Besides, the structure of the mouthpiece is very simple, so the productive efficiency of the mouthpiece is excellent and it can be manufactured at a low price.

Further, the mouthpiece can be provided and fixed on the conventional pump for discharging bubbles 10 of this kind.

The following experiment was performed in reference to the opening diameter L of the nozzle 502.

The discharging state of the bubbles was measured by using the container with a pump for discharging 173 bubbles of the above-mentioned structure and changing the opening diameter L of the nozzle 502. In the measurement, the discharging state when the bubbles were discharged upon the target body separated at 15 cm from the nozzle 502 was observed visually and the pressure sense at the moment was examined. The result is shown in the following Table 1. Further, the pressure sense of the pump head 100 is referred to as "head pressure" in Table 1.

174 0 Discharged in a linear shape smoothly.

A Discharged liquid curved and descended in the observed distance.

X Discharge liquid Curved and descended in a shorter distance.

Besides, the codes O, A and X in the item of "head pressure" indicate the following criteria.

*o* 0 Can be pressured lightly.

X Pressured rather heavily.

et .a Accordingly, it is preferable that the opening diameter of the nozzle 502 is less than 2.0 mm, because the bubbles can be injected linearly at the distance of at least 15 cm when the opening diameter of the nozzle 502 is less than 2.0 mm. On the other hand, it is preferable that the opening of the nozzle 502 is within the range of 1.0 mm 2.0 mm, because the pump head 100 is pressured heavily when the opening is too small.
