container

1,2, enters the opposite in hole 10 at air, and when this film 4 is not held, it be placed in bracing or strutting arrangement 22 above.Film 4 is realized by single annular element, but is not limited thereto.

[0019] air enters hole 10 and combines with locking device, and locking device for example is a film, the direction circulation or the circulation that allow air only to suck towards inside with the outside from container.By Fig. 1 representative be not the embodiment of the mode that is used for limiting, film 4 is placed on the opposite in hole 10, if allowing air to enter under the situation about holding and air flows out from

container

1,2, then blocks air.When

container

1,2 pressure inside during greater than the pressure of outside, opening 10 air by baffle plate flow out.According to the physical phenomenon of suction, film 4 is close to opening 10.When film allowed film 4 to have seal with respect to the elastic property of opening and material and impel air towards the outer loop of bottle, the pressure in container remained unchanged.

[0020] when the user unclamped pressure on container, because the elastic property of container deformation material, container returned to its original-shape.Get back to its original-shape, compare, in container, produce low pressure with external pressure.Therefore air is inhaled in the container 1,2.By pushing film 4b open, air is by opening 10) enter, therefore film is placed on the bracing or strutting arrangement 22.Air therefore only can be with the direction circulation that enters.

[0021] power of pump is to be applied to pressure on the soft bottle by the user.When the user pushed deformable bottle 1, inside and film 4 obstruction air that pressure is applied to container entered opening 10.Compressed-air actuated volume will be exerted pressure to akaline liquid (liquide de base) 9, and akaline liquid will be pushed in blender 6 by dip-tube 5.On the other hand, portion of air flows out by blender 6, and the gas port 13 by blender 6 passes through.Foam is produced in the outlet 11 of blender 6, and the outlet 11 of blender 6 connects the despatch room 12 of foam.When the user unclamped pressure on container 1, because the elastic property of material, container 1 returned to its original-shape, and air is inhaled into.The film 4 in control air supply pipe road 10 will be promoted again, and the air that has discharged in

container

1,2 enters opening 10.Then

container

1,2 usefulness surrounding air is filled once more.Each its shape representation, the each new pressure of user produces new foam.Preferably, by the user pump is remained in position.

[0022] Ping bottle cap 2 is discharged foam by the opening 11 of foam distribution.By realizing the foam despatch room 12 of guiding or conducting device, next, foam is by guard shield 3, and foam is spendable for the user in conduit 18 outlets.The outlet 11 of foam distribution is connected to blender 6, therefore can not be directly and

container

1,2 connection.

[0023] blender 6 allows akaline liquid 9 and air floatation, so that produce foam.Liquid 9 flows towards blender 6 directions by dip-tube 5.Air is introduced in the blender 6 by gas port 13.Air enters into the chamber of blender and contacts with the different elements of blender, for example grid and needle-valve.In order to produce foam, air promotes in blender simultaneously with the liquid 9 that contains the reagent that foams.Similarly, liquid enters in the chamber of blender and contacts with different elements in the blender, and for example dip-tube 5 enters grid 7a, outlet grid 7b and needle-valve.In order to realize emulsification, the flowing of akaline liquid 9 at first by being placed on needle-valve 14 multilateds in the groove.From definition, needle-valve is the adjuster of flow.Baffle plate 16 remains on original position with needle-valve.When the user did not exert pressure on bottle, by the pressure gently that his finger applies, then needle-valve 14 block liquid flowed.

[0024] when the user exerts pressure on deformable bottle, alkaline product 9 flows back in the pipe, and needle-valve lifts, and product liquid 9 is passed through, and has changed the flow of liquid 9, produces disturbance, and it begins emulsification.The flow of liquid is big more, and needle-valve is swing or stirring more.Needle-valve comprises and is immersed in the bottom in the liquid line and is used for top at the broad that flows of the head seal liquid of needle-valve.When the user exerted pressure, the air in container was exerted pressure to liquid, and this liquid flows back in the dip-tube 5.User's applied pressure is big more, and the flow of foam liquid is big more.The flow of liquid is big more, and needle-valve will be got over swing tempestuously.The flow of liquid has also been confused in the swing of needle-valve.This flow that has reduced liquid on the one hand that stirs has been realized the initial emulsification of product liquid on the other hand and has been begun to form foam.

[0025] on the other hand, air mixes with liquid 9, part in the first grid 7a emulsification of blender 6 and before entering into distribution opening 11 in the second grid 7b emulsification.According to user's applied pressure, after the needle-valve swing and after first or second filters, this liquid is emulsified more or less.According to applied pressure, the user will obtain different foam-types, and foam is soft more or less.Foam leaves with the outlet 18 by this chamber 12 by despatch room 12 subsequently.

[0026] produces foam by on deformable bottle, applying Manual pressure, can control the quality of foam.In fact strong or soft according to user extruding, foam has different denseness or uniformity (consistances).And according to long-time extruding of user or short time extruding, the foam volume of generation is different.The foam volume that produces is not unlimited, but the container of

big volume

1,2 allows to discharge a large amount of air and a large amount of foaming, to produce a large amount of foams.Bottle cap 2 is fixed at annular opening 20 places of deformable bottle 1 by obturator 21 in airtight mode, is contained on the deformable bottle.But therefore the user can load onto identical bottle cap 2 with the deformable bottle that has different volumes have the opening of same size.The size of deformable bottle for example, is more or less swelled or is raise more or less according to bottle and change.The different size of container is suitable for concrete purposes.In order to produce foam in large quantities, jumbo container will be used and in order only to produce foam in a small amount, for example in order to save valuable product, small container will be used.Soft more or less speed and the type that has changed the foam that produces equally of container.

[0027] specific embodiment of blender 6 shows in Fig. 2.Conical blender 6 obtains by tightening nozzle 2.The air 13 that enters mixes between the baffle plate made from plastics 23, represents with the hacures element.Baffle plate 23 connects between the 7b at two screen 7a of sieving.Needle-valve 14 highly is defined by moving stop 16 in its position, and the pyramid type chock tube 19 of needle-valve head, and it has cone shape too.The air that exists in

container

1,2 can be passed through by opening 13, is incorporated in the blender 6.

[0028] in an exemplary embodiment, the dip-tube 5 in liquid is made up of the pipe of a plurality of parts, different-diameter, and some are embedded into the length that allows product is kept outflow in other.Dip-tube 5 for example is fixed in the blender by tight fit, so that dismounting and replaceable easily.Long or the short pipe that is comprised will be suitable for the dark or shallow deformable degree of depth of deformable bottle 1.Preferably, for the product 9 that can use all akaline liquids in

container

1,2, the bottom of the internal heads passage deformable bottle 1 of pipe.As long as dip-tube 5 is immersed in the liquid 9, pump just keeps its function.

[0029] pump of deformable bottle 1 is designed to and can removes from nozzle 2.Deformable bottle 1 comprises, and the rigid circular thing at circular open place at it is used to make nozzle 2 to close and closes.When container was disassembled, therefore the user can recharge container by enough akaline liquid products 9.Pump is also changed by the user.Not that the embodiment that is used to limit is included in alignment target is set in the container, be used for transparent height or the level that shows product by container.

[0030] in exemplary embodiment, guard shield 3 can be placed vertically with respect to nozzle 2 by spiral helicine connecting portion.At the place, high position of guard shield 3, foam pump is used as the front is described, and at the lower position place of guard shield 3, it blocks the discharge of flowing of air supply and foam.For each opening is closed in the lower position place of guard shield, each highlight 15 of each guard shield 3 is equal with respect to extended distance.In another embodiment, guard shield 3 has smooth support and connection with bottle cap 2, and keeps by the internal lock system at the lower position place with respect to the guard shield 3 of bottle nozzle 2, has replaced the spiral connection.
