• a rotatable and vertically movable handle disposed atop the second receptacle 3 to block or unblock said second path;
• a rod originating from said handle and passing through said first 5 and second receptacle 3 and connected to the valve 6 within the first receptacle 5 for opening or closing said first path 6a.

• Figure. 3 illustrates different isometric views of the dispensing apparatus 100 of Fig.l in upright and inverted positions. While Fig. 3a and Fig 3d depict isometric views of the apparatus 100 in the upright positions, Fig. 3b and Fig. 3c depict the isometric views in inverted positions. As shown in the figure, both Fig. 3a and Fig. 3b describe an Open first path' and a 'closed second path' position, thereby corresponding to a default position of the dispensing apparatus 100. The open first path has been represented by the numeral 6a at Fig. 3b. On the other hand, both Fig.3c and Fig. 3d describe a 'closed first path' position and an "open second path' position, thereby corresponding to an actuated position of the dispensing apparatus 100.
• the actuated state is achieved by rotating the actuator 2.
• the actuator 2 may be rotated in a clockwise direction as shown in Fig. 3d, when seen from the top of the dispensing apparatus 100.
• the valve 6 connected to the actuator 2 also gets displaced from its default position, as shown in Fig. 3c and appears to have been rotated in an anti-clockwise direction, when seen from the bottom of the apparatus 100.
• the first path 6a gets blocked by the valve 6, while the second path 8 is unblocked.
• the second path 8 or the aperture 8 is visible as shown in Fig. 3d.
• the quantity of substance collected in the second receptacle 3 is prevented from reverse-flowing into the container 7 through the first receptacle 5. Also, due to such closure of the first path 6a, the second receptacle 3 is completely evacuated through the second path 8.
• the role of the second receptacle 3 to provide and maintain the collection area, inspite of the second receptacle 3 moving away from the first receptacle 5, is further assisted by the gasket 4 acting as a fool-proof sealing mechanism between the first 5 and the second receptacle 3.
• the movability of the second receptacle 3 with respect to the first receptacle 5 is restricted by a limit, for example, by formation of a knuckle joint between the first 5 and the second receptacle 3 at a particular raised position of the second receptacle 3 with respect to the first receptacle 5. Such joint also assists firmly holding the second receptacle 3 at the highest raised position.
• the actuator 2 may be connected to the valve 6 through a telescopic arrangement, thereby facilitating a longitudinal motion of the actuator 2 with respect to the valve 6 that is although rotatable but stationary.
• Figure 4 illustrates various steps of operating the dispenser 200 of Fig. 2, in accordance with an embodiment of the present invention. Without limiting the scope of the present invention, entire operation has been classified as comprising at least four steps (1-4). However, the depicted steps shall be construed to cover various other analogous steps as well as additional steps that may be ancillary to the currently depicted steps.
• the removable cap 1 which is removably fixed at the first receptacle 5 with a screw-thread mechanism or through any other removable joining mechanism, is removed from the first receptacle 5. Accordingly, the second receptacle 3 and the first receptacle 5 enclosed by the second receptacle 3 are now exposed and become accessible by a user.
• Step 2 the container 7 of the dispenser 200, which in the current example is a deformable or compressible tube 7, is actuated by a user performed action such as squeezing, compressing, deforming etc, so as to generate an outward flow of the viscous substance (i.e. semi-solid) from the tube 7 towards the first receptacle 5.
• the first receptacle 5 receives the flow and directs the flow through the first path 6a as depicted in Fig. 3c.
• the directed flow accordingly reaches the second receptacle 3, and pushes the second receptacle 3 away from the first receptacle 5, thereby creating a collection area bounded by the first 5 and the second receptacle 3. Accordingly, the flow starts getting collected within the second receptacle 3.
• the container or tube 7 is squeezed further till the viscous substance collection within the second receptacle 3 corresponds to a required level of weight, say 3 grams.
• a required level of weight say 3 grams.
• the graduations may also correspond to other units corresponding to volume (milliliter), pressure (psia, psig, psi) etc.
• the flow of the semi- solid from the container 7 to the second receptacle 3 also gets stopped, and a final quantity of the substance collected in the second receptacle 3 is observable in terms of units like milligrams, milliliter or psi.
• Step 3 when the required dose has been obtained, the actuator 2 is actuated, for example by rotating in the exemplary direction as depicted under Fig. 4c to expose the second path 8 or the aperture 8 provided within the second receptacle 3 so as to later facilitate dispensing of the semisolid from the second receptacle 3.
• the valve 6 within the first receptacle 5 rotates to close the first path 6a (Refer Fig. 3c) so as to prevent the reverse movement of semisolid from first receptacle 5 to the container 7 and to also assist a complete dispensing from the second receptacle 3.
• other type of actuations like linearly pushing or pulling the actuator 2 are also conceivable, for example by employing a linear actuator, to perform the aforesaid shutting and closing of paths.
• step 4 the second receptacle 3 is depressed vertically for evacuating it completely. As a result, an entire quantity of substance collected within the second receptacle 3 oozes outside, through the second path 8 or the aperture 8. Further, as the second path 8 acts as the only opening within the second receptacle 3 and owing to an already shut first path 6a, the second receptacle 3 is evacuated completely and the user is able to retrieve an entire measured quantity. In other example, and also shown in Fig. 4d, the actuator 2 located atop the second receptacle 3 may be instead depressed to facilitate the depression of the second receptacle 3.
• the present dispenser 100 is configured to dispense accurately and substantially greater metered amounts of semi-solids, when compared with the conventional dispensing systems for viscous substances.
• the present dispenser 100 is configured to dispense amounts ranging from 1 gm till 5 gm or 1 milliliter to 5 milliliters accurately.
• the present invention is able to collect a metered quantity of the substance and thereafter dispense it without employment of any energy generation/conservation means such as spring, coil, electricity-generated mechanical force, or propellants such as compressed gas or aerosol.
• the present invention employs a human hand driven force, akin to pressing of a control button, to retrieve the metered substance out of the dispenser 200.
• absence of any energy conservation or generation means within the dispenser 200 imparts it a simple architecture.
• the kinetic flow of viscous substance required by the present invention to enable collection of the viscous substance within the collection area is simply attainable by a compression or deformation of the container 7.
• a manually generated compression such a squeezing of the deformable container 7 (that may be in an example is a plastic or, an aluminum or laminated tube) is enough to meet the kinetic flow requirements of the present invention.
• the present invention is able to dispense the semisolid or liquids irrespective of the viscosity of the substance. Accordingly, almost any non-gaseous and non- solid substance that falls under the category of a viscous substance is operable by the present invention.
