Fig. 1 to Fig. 4 represents dispensing cartridge 10, and it is made up of two superimposed panels 11 and 12.The element of common numerical code expression and structure are corresponding to my element and the structure with same numeral in US 5000350 and 5067835.Box forms a hopper 13 (Fig. 2), is used to store the liquid article of high viscosity, as soap, and shampoo, catsup, mayonnaise, oil or other appropriate liquid shape article of thickness.

In a preferred embodiment of the invention, plate 11 and 12 is two independent composite plastic plates (for example nylon/polyethylene laminator, 6-8 mil thick), and is superimposed each other and substantially along its peripheral heat-sealing, shown in latasuture 14 and 14 ' in the manufacturing process.In the starting stage of encapsulation process, the upper end 15 of ingredient capsule can be opened wide, so that liquid article can charge in the box at the beginning, after this upper end is sealed.Another kind method is behind the hopper filled with articles, can seal to the process flat board 11 of deep drawn dull and stereotyped 12.As later to illustrate, pumping system 16 combines with the sort of ingredient capsule illustrated in my patent above-mentioned, sends to guarantee the high viscosity article that will be encapsulated in effectively wherein.

For the ease of installing, pass the last abutted seam of box and can do one or more holes 17, as described in my patent above-mentioned.The lower end of box is preferably partially enclosed by the leak free plate in manufacturing process, and described plate has partly constituted movable closure member (not shown).For example when the user used ingredient capsule, available scissors cut off this closure member.

The composite metal extruding composite plastic of illustrated the sort of pattern is made in each piece plate 11 and the 12 the most handy patents that I mention in the above, and the disclosure of these patents at this as a reference.The single-piece thickness of plate and composition can become according to special user's request for product.For most of family expenses and industrial use, the composite thickness of each piece plate is preferably in interior selection of approximate extents of 3.0-10.0 mil, and box can be stored the liquid article of 50-5000 milliliter in its hopper 13.Moreover, the total length of wishing most of ingredient capsule in 10.0-36.0 centimetre approximate extents, and hopper 13 (Fig. 2 centre joint 14 and 14 ' between) the inside maximum width be 5.0-12.0 centimetre.

Pumping system 16 comprises the plug-in unit 18 (Fig. 5) of a single-piece and button shape, and it is clipped between plate 11 and 12.When dull and stereotyped 12 seal to plate 11, after plug-in unit falls into dimple identical shaped on the plate 11, as needs, the relative garden circumferential portion 19 of the diametric(al) of the plug-in unit of moulding in advance (Fig. 2) can seal at least one block of plate, preferably seals between two boards.As the back with reference to figure 7 to Fig. 9 described, when pumping pressure was applied on the box, pumping system can be sent the liquid of higher tack from box.

In order to reach desirable pump action, plug-in unit can be by polyethylene, and rubber or other have adequate thickness and size, and the suitable material of physics and mechanical specialities (for example hardness 60-80 of hardness meter (durometer) mensuration) is made.Fig. 1 is in the lax state to the plug-in unit of moulding in advance shown in Figure 5, and it has constituted fills material chamber 20, and this fills expects that the chamber communicates with many passages or groove 21 again, and groove 21 is made on the circumference, passes the bottom surface of the annular mounting flange 22 of plug-in unit.Fill the material chamber and be used to store the liquid fraction that measures in advance, the chamber is that the inner surface portion by the plate 12 on the spherical part at plug-in unit center and opposite constitutes.

When the spherical part of plug-in unit or drum convex portion by being positioned at the plate 11 above it, by compression the time, the pump action of generation is enough to by lowermost groove 21 (Fig. 2) liquid be sent from filling the material chamber from the outside.The spherical part of plug-in unit can be from regaining its normal expansion condition when the pumping pressure removal, to shown in Figure 5, is that the next one send work get ready thereby make ingredient capsule as Fig. 1.Simultaneously, along with the automatic expansion of plug-in unit, the pressure in the chamber 20 reduces (parital vacuum) relatively, adds the effect (ingredient capsule is generally vertical installation) of gravity, makes the liquid fraction that measures in advance charge into once more the chamber 20 from hopper 13.

In a preferred embodiment of the invention, the spherical part of plug-in unit at least totally is seen as semisphere (Fig. 3 and Fig. 5).In addition, though pumping system of the present invention is the box that adopts disclosed the sort of form among the US 5067635, yet more wish to adopt the box of the sort of form of being set forth among the US 5000350, in this box, its plate 11 is process deep drawn, so that the side at box can obtain graphic expansion condition, and plate 12 is flat at least substantially.The cavity that forms in the plate 11 is consistent with the profile of plug-in unit 18, also is preformed during the stage in the deep drawn of making box.

Can find out that with reference to Fig. 1-Fig. 4 pumping system 16 is in the downward awl neck or in the ingredient capsule discharging opening 23.As illustrated in the above-mentioned patent of applicant, the terminal of discharging opening is positioned on the lower end at valve 24 places, and it comprises a normally closed passage 25 (Fig. 2), has formed the delivery port of box, and it communicates with the lowermost end delivery channel 21 of pumping system 16.Passage 25 is preferably oblong and straight, and is made of the superimposed part of plate 11 and 12, and superimposed part is flat substantially, and is pressed together with valve-off.

Discharging opening 23 has many parallel channels 26 as the wafer, and they are made on the plate 11, communicates with hopper 13, feeds filling of pumping system 16 in order to the liquid fraction that helps periodically will measure in advance and expects chamber 20.Passage 26 constitutes the input port in chamber 20, the cross-sectional area of the cross-sectional area specific output passage 25 that it is total much bigger (for example 4 times).When ingredient capsule is is vertically installed and used, as will describing in detail later on, be stored in hopper 13 and fill the high viscosity article of expecting in the chamber 20 and can not leak, because valve 24 is normally closed.The compression of the spherical part of plug-in unit 18 (Fig. 9) will make valve 24 open, and article are sent from fill material chamber 20.

When pressure was eliminated, plugin table revealed enough rebound characteristicss and " memory " function, makes plug-in unit can regain the condition of its normal expansion, and as Fig. 1-shown in Figure 5, this puts the high evaluation that also will obtain technical personnel in encapsulation field.Meanwhile, in filling material chamber 20, will produce negative pressure (parital vacuum) (valve 24 SELF CL are to prevent to fill the influence that the material chamber is subjected to external air pressure).Like this, the predetermined liquid fraction of another burst will be by any gap between passage 26 and plate and the flange 22 (Fig. 3), from hopper 13 inflow chambers 20.Effective work of pumping system can guarantee that at least substantially all the article of encapsulation can both be utilized by the user.

Fig. 6 is illustrated in a kind of comprehensive proportioner 29 illustrated among the US 5000350.This device comprises a mounting bracket 30, and the adhesive agent of its available standards or other suitable fasteners are inserted by the hole 31 of running through plate behind the support and be fixed on the wall or elsewhere.By first cover 32a of two lids of forming of part by two laterally the pins 33 of placements can be installed in the lower end of mounting bracket pivotally, pin is installed in the groove 34.Make a flange 32b in the upper end of cover 32a central authorities, on a fixed position that under normal circumstances lid is remained on mounting bracket.Also have cantilevered spring 30a (only expressing), under normal circumstances, the sheet spring is attached on each pin 33.

Done many finger-holes (not illustrating among the figure) by the bottom surface of mounting bracket, sheet spring 30a is unclamped from pin 33 easily, this mode has been illustrated in US 5000350.Particularly, cover 32a can raise, and enters groove 34a with upward movement forward, outwards does on pin 33 then pivotally and rotates, and can expose the box 10 shown in the dotted line like this.Installation pin 35 is fixed on the front of mounting bracket 30, is used for detachably installing box 10.If wish to do like this, then can use a pair of horizontal separated pin and accommodation hole 17 (Fig. 1) thereof.

Lid also comprises second cover or pressing plate 32c, and it is installed on the support 30 pivotally by pin 32d (only representing 1).When in order to prepare burden, as Fig. 7 to Fig. 9 order is represented, with pressing plate 32c during towards mounting bracket 30 pushing, compression set 37 will compress, and apply a downward pumping pressure on pumping system 16, and valve 24 is opened (Fig. 9), the liquid product share that measures is in advance sent from fill material chamber 20.Compression set comprises a gauge finder or pressure plate 38, and pressure plate 38 is installed on the medial surface of pressing plate 32c pivotally by two pins 39.

The upper end of pressing plate is born the elastic force bias of compression coil spring 40 usually, keeps and relative " gently " of box and contacting of not dispatch.Like that, handle or finger pressure are added to and can make this pressing plate do pivot type rotation around pin 32d on the pressing plate 32c shown in Fig. 7 to Fig. 9 order.The last seamed edge 38a of pressure plate 38 moves to when beginning and is line with the upper end of discharging opening 23 and contacts, and horizontal resting on the passage 26 filled the material chamber to stop more liquid to enter.The pressure that motion produced of gauge finder generally is that imitation applies the finger pressure of downward pressure on discharging opening 23, so that dispatch, is a kind of action of the formula of milking.

As shown in Figure 9, continuous stress will make pressure plate 38 center on seamed edge 38a to pressing plate 32c and rotate, thereby will fill material chamber 20 emptyings fully.When loosening pressing plate, spring 40 will make pressing plate and pressure plate return back to their normal positions at Fig. 7.Then, fill material chamber 20 more automatically by passage 26, material is filled in any gap between groove 21 and dull and stereotyped and the flange 22 (Fig. 3), for the next dispatch action of device is prepared.Central authorities at cover 32a are equipped with a watch window 41 (Fig. 6), can see the amount that liquid reduces in transparent box 10 by naked eyes.

As Fig. 7 to Fig. 9 more clearly represented, mounting bracket 30 had a static mounted panel 42, and it and support are made an integral body.If desired, then as shown in figure 10, on stay bearing plate, can fix a pinch device with block 43 forms, when doing pivot type rotation downwards with convenient pressure plate 38, can control better accurately close from hopper 13 to the chamber 20 inlet.Block can be done the shape of cross section of wedgewise, and its terminal promptly is seamed edge 44 on its top, when the dispatch effect begins, can contact and close with the whole width retention wires across discharging opening 23 and block 43 like this.The panel material that constitutes the box wrinkle part of passage 26 should have enough " memory " characteristics, and it can make that passage can regain the condition of normal standard-sized sheet after pumping pressure is removed from box.

Normally closed valve 24 preferably with applicant's the sort of similar described in US 5000350 and 5067835, but its size and structure can be designed to keep under normal condition " slightly " to open.In a back patent, the size of delivery channel 25 (cross-sectional area and length) should be complementary with the viscosity that is encapsulated in the particular fluid in the metering device, in case stopping leak leaks.Especially when metering device is in its normal pre-dispatch condition (Fig. 7) since the viscous effect of liquid before pumping system 16 actions, can not leak by delivery channel.

Figure 11 represent the ingredient capsule 10 of a remodeling ', the cavity of laying plug-in unit 18 is made in the plate 12 rather than in plate 11.Pumping system 16 disposes to such an extent that make its contact and compresses an opposite side of remodeling box.The passage of wafer shape can be made on plate 12 (Figure 11) or the plate 11 (Fig. 1 to Fig. 4).The box of remodeling can be installed in the proportioner 29 (Fig. 6), and its mode of operation and above-described box 10 are just the same.
