Thereby eliminated the risk of distributing box fault and kept the water tightness of container.

Explanation below reading with reference to the accompanying drawings will be understood the present invention better, in the accompanying drawing:

Figure 1A and 1B are respectively the axial cutaway view of embodiment of pump in accordance with the present invention in dead position (having cover) and distribution locations (not cover).

Fig. 2 to 5 is the pump detailed section view in the different step of distributing this product among Figure 1A, the 1B.

Dispenser designs composition shown in Figure 1A and the 1B is equipped with and batches liquid product and do not have air admission in container.

Thereby this product is stored in the osed top atmosphere, isolates with external environment and separates with any pollutants, and this is basic to the sensitive product such as cosmetics or drug products.

This distributing box has pump P, and pump P is included in the cylindrical pump housing 1 that the bottom is opened wide fully, and the pump housing leads to the container R that is stopped up by moveable base F in the bottom.

Container R according to the present invention also comprises unlimited support base E.

Distributing box shown in Figure 1A is to be positioned to have the static and/or storage location of covering C.

Product is full of the whole volume of container R and rises to the internal volume of the pump housing 1.Thereby the bottom margin of the pump housing 1 immerses in the product as shown in FIG..

By piston closes, this piston contacts with product at the top for the pump housing (body) 1.Piston is made of the ring of installing around middle jet pipe 3 bottoms 2.

Ring 2 has the two edge 23 of radially outer, and it can slide with the inwall wipe contact ground of the pump housing 1.

Ring 2 is assembled on the pipe 3, has the small crest clearance that is parallel to the discharge-channel 30 of at least one lateral arrangement on pipe 3 respectively between two bottom 31a and top 32a backing block.

This ring has ring in the tapered cylinder, its top 22 and 21 zones, bottom, and according to the pressure by liquid transfer, alternately watertight ground contacts with top 32a backing block with the bottom 31a of pipe 3, thereby as shown in Fig. 2 to 5, opens or close discharge-channel 30 as valve.

The bottom of pipe 3 has the conical lower portion 31 with flat edge, and its end face forms bottom stop piece 31a below 30 height of hole.The bottom axial end portion of pipe 3 is stopped up in bottom 31.

More than the height of discharge tube 30, the bottom of pipe 3 has the shaft shoulder 32 on every side, and its bottom surface forms the top backing block 32a of ring 2.

Zone 21,22 arranges with about 160 ° to 170 ° angle, guarantee they respectively under the situation in zone 22 by outer wall against pipe 3, under the situation in zone 21 by 31 end face keeps against the bottom.This reinforcement is supported and is guaranteed the water tightness of valve at detent position.

Ring 20 limits with pipe 3, and parallel with hole 30, very little separating turns to space (dividing turning space), and it allows product to expand before by hole 30 and discharges under pressure.

When opening of valves, the bottom section 21 of the sloped top face of conical lower portion 31 guided rings 20 in the relative upward movement process of ring 20.

Between ring 20 and the tube wall, the friction drag fb between bottom section 21 and bottom 31 end faces lower (being between 50 to 100g) particularly, and under any circumstance, be lower than the friction drag fa (order of magnitude of 700g) between 2 pairs of edge 23 of ring and the pump housing 1 inwall.

Consider the apparent surface of bottom 31 and bottom F, friction drag fb also is lower than the friction drag fc (3 to 4kg the orders of magnitude) between moveable base F and the container R inwall.

The pump housing 1 is partially enclosed by inner liner 10 at the top, and lining 10 has top ring 13 and the bottom part ring 12 that is used for guiding tube 3, and bottom part ring 12 has bigger diameter, is used for stopping up piston at the off position of discharge-channel 30.

The end face of ring 2 comprises circular rib 24, and it limits groove 25 with the top area 22 of ring 20, and the bottom part ring 12 of pump housing lining is inserted in the groove 25.

As shown in Figure 1A and 1B, the top of jet pipe 3 is connected to and is arranged in freeing pipe 40 in the actuator 4, and actuator 4 has external baffle 41 and inner cylinder sleeve 42.Sleeve 42 is designed to cover the pump housing 1 with sliding type, will remain in the space of separation around the spiral retracing spring 5 that pipe 3 is installed.

The foundation ring of spring 5 and top ring 13 are coaxially against lining 10 end faces.

The pump housing 1 is fixedly connected to the top margin that is used to be connected container R on the peripheral flange ring 14 by lateral partitions 11.

Flange ring 14 extends upward by raised edges 15, and edge 15 can housing C in the outside, and cover C can have locking or bolt device, and edge 15 can hold the baffle plate 41 of actuator 4 in the inboard.

Removable bottom F comprises central cup f, and this cup has the profile with the profile complementation of managing 3 conical lower portion 31 and/or the pump housing 2 bottoms, thereby the assurance container is turned fully.

Because piston does not run into any backing block in it falls into the process of the pump housing 1, thereby lateral plane zone 11a is arranged on the dividing plate 11, is used for quantitative purposes.Stop thereby the bottom margin of actuator 4 baffle plates 41 leans against on this plane domain, make except loading spring 5, also can limit the product dosage that is provided.

A kind of variation can comprise by the bottom that makes sleeve 42 and being parked on the dividing plate 11, perhaps even by spring 5 housing top wall are leaned against on the pump housing 1 top, and the stroke of limited piston.

Illustrate in greater detail the operation of pump below with reference to Fig. 2 to 5.

In the position shown in Fig. 2, dispenser stationary is motionless, and cover C seals actuator 4 and pump P still.

Blow off valve and discharge-channel 30 are closed.

The zone 21 of piston ring 20 keeps watertight ground contact bottom stop piece 31a by the application force of retracing spring 5 and by this application force that bottom part ring 12 is transmitted.

In position shown in Fig. 3, after removing cover C, the customer applies Manual pressure to actuator 4.

This pressure makes spring 5 compressions, and makes pipe 3 pass ring 13 declines.Conical lower portion 31 immerses in the pump housing 1 and produce pressure in product then.

But this pressure is considered the wipe contact (fc resistance) between moveable base F and the wall of container R, and deficiency is so that bottom F decline.

Simultaneously, wipe contact (fa resistance) between two edge 23 of piston and the pump housing wall produces resistance of motion, this makes in ring 2 is during certain motionless, during this period very short but be enough to (considering lower fb resistance) and allow zone 21 to separate from bottom stop piece 31a, and, allow zone 22 to stop on the backing block 32a of top according to the value of crest clearance.

Product infiltrates the space of stripper loop 20 and pipe 3 then, and begins to flow out by hole 30, schematically shows as the arrow among Fig. 3.This is the beginning of allocation step.

Pressure on the actuator 4 continues, and because pressure raises, the resistance of ring 2 is overcome.

Product distributes in mode clocklike by managing 40.

Pipe 3 continue to descend, and leans against plane domain 11a up to baffle plate 41 and goes up and stop thereby promoting ring 2 downwards, and as shown in Figure 1B and 4, wherein bottom 31 is outstanding slightly downwards on the outside of the pump housing 1, still immerses in the product simultaneously.

In this, the customer knows the product that doses is provided.

Pressure on the release actuator 4 causes internal pressure to disappear immediately, and manages 3 to rising back then.

Equally, because the resistance that causes of friction, ring 2 keeps static contact of wall with the pump housing in the very short time, and this time is enough to make bottom stop piece 31a to get back to the bottom section 21 that encircles to contact and close this valve, as shown in Figure 5.

Pump is got back to stop position along with valve closing under the effect of retracing spring then, pipe push back the ring 2 up to its lean against the ring 12 on and stop.

Simultaneously, moveable base F rises and enters container R, with the volume of compensation institute allocated product.
