The system for extracting, dosing, dispensing, with controllable regular and continuous flows, liquids and creams from their container, in the absence of gas, comprises a thick hollow rod provided with low-softening means to seal a thermoplastic sac on which is shod an elastomeric balloon.
대표청구항▼
The invention claimed is: 1. System for extracting, dosing, dispensing with controllable, regular and continuous flows, liquids, creams, chocolates, jams, fruit, squashes and the like, from a container thereof, said system generally comprising an inner tube, a sac, a balloon, a bottle, and a valve,
The invention claimed is: 1. System for extracting, dosing, dispensing with controllable, regular and continuous flows, liquids, creams, chocolates, jams, fruit, squashes and the like, from a container thereof, said system generally comprising an inner tube, a sac, a balloon, a bottle, and a valve, wherein said inner tube is a hollow rod (TU, TU') which extends from the top to the bottom of said container as an integral mono-body element comprising: inlet-outlet holes (FO, OL) in the highest possible position on said inner tube for said liquid or cream to avoid the formation of air bubbles; and a bulkhead (BH) substantially beneath said inlet-outlet (FO, OL holes) defining within the hollow rod a major blind portion (BL) between said bulkhead (BH) and the a male top-shaped bottom terminal (TO); said rod being provided with a thermoplastic liquids-containing sac (SAU) having a bottom female cavity (FC) to accommodate the male top-shaped bottom terminal (TO) of said rod, wherein said male top-shaped bottom terminal has a throat (GO) that couples with said female cavity. 2. System according to claim 1, characterized in that said rod is provided at its head with a collar having annular protrusions made of a thermoplastic material having a softening point lower than the melting point of the rod forming material. 3. System according to claim 1, characterized in that said bottom male top-shaped bottom terminal (TO) is shaped inversely to the female cavity in the bottle container. 4. System according to claim 1, characterized in that a small cylinder (CC) covered with rings (MR) made of high friction material is movably inserted in said blind portion (BL) of the rod, whereby few up-down strokes of said high friction rings on (CC) generate sufficient heat to enhance the floatability of the liquids or creams within the sac. 5. System according to claim 4, characterized in that said thermoplastic sac (SAU) is provided with an open mouth (B) to fit and seal on the low softening material of the collar protrusions (MR). 6. System according to claim 1, characterized in that the sac (SAU) has an umbrella like structure. 7. System according to claim 1, characterized in that said bottom female cavity (FC) is formed of an elastomeric balloon or vesica (PA). 8. Method for the embodiment of the system according to claim 1, comprising at least the following steps: I) assembling the hollow rod with a tap and cap; II) sealing a thermoplastic sac at the upper and lower ends of said rod; III) fitting an elastomeric balloon or vesica (PA) well shod on the thermoplastic sac (SA); IV) inserting in a bottle the assembly of the rod carrying tap and cap, of the thermoplastic sac and of the elastomeric balloon; and V) filling thee sac. 9. Method according to claim 8 comprising the steps of providing the hollow rod with: (a) a male top-shaped terminal at the bottom thereof; (b) a collar having ring protrusions made of a material with a low softening point at its upper portion; (c) an upper bulk-head; (d) a movable cylindrical body having high friction annular protrusions; welding the mouth of an umbrella like sac to said low softening ring protrusions and welding or fitting said male terminal of the rod to a female cavity in the bottom of said umbrella sac; inserting the so assembled rod-sac within an elastomeric balloon also provided with a bottom female cavity; applying a tap and a cap on the rod head; inserting the rod-sac-balloon-tap-cap assembly within a bottle or bag-box, and filling the sac with the liquids, creams, and the like, to be dispensed.
