Description

FIELD OF TECHNOLOGY

The present invention relates to an integrated liquid dispenser configured to deliver an accurate dose of liquid products and, more specifically, to provide an accurate dose of liquid pharmaceuticals for oral use / drinks, etc.

BACKGROUND

It is well known in the art that many pharmaceutical preparations and drugs are presented in liquid form to facilitate oral administration to patients, such as children, elderly patients and patients having difficulty swallowing solid dosage forms. The most commonly available oral fluids are supplied in a container, such as a vial, together with a dosing aid, such as a measuring cap, spoon, oral syringe, dropper, etc. Using these types of vials and dosage aids, the patient is faced with a number of problems, as follows:

• Each time, in order to dose the patient / nurse, it is necessary to open the container by removing the lid or stopper and measure the dose from the container into the dosing auxiliary device, rinse the dosing auxiliary device and return it back to the container.

• Since most liquid oral medications are sugar-based, flushing the measuring accessory becomes critical, failure to flush can harden residue deposits and contaminants.

• In some dosing aids, such as a measuring cap or spoon, dosing accuracy is impaired, resulting in an insufficient dose or overdose.

• If the solution is viscous, then with multiple use, dosing may not be carried out.

• The dosage aid must function until the completion of the liquid drug in the container and, therefore, proper storage is essential, which is a time-consuming process.

Thus, there is a need to provide an integrated drug dispenser for delivering an accurate dose of liquid drugs.

SUMMARY OF THE INVENTION

In an embodiment, the present invention provides a device for providing a metered supply of fluid, said device comprising a first chamber formed by a first cylinder and having a first opening; a second chamber formed by a second cylinder and having a second hole, the second cylinder being placed inside said first cylinder; and an element representing a lid interacting with a second chamber to form a storage portion; moreover, in the first state, the first and second holes coincide with each other to form a path with the possibility of a metered amount of fluid to flow from the fluid source into the second cylinder for accumulation in the specified storage section; wherein the second cylinder is movable relative to the first cylinder or vice versa to achieve a second state, wherein in the second state, the first and second openings do not coincide with each other, thereby blocking the path; wherein said first cylinder forms a displacement limit for said second cylinder.

In another embodiment, the present invention provides a dispenser for dispensing a liquid, said device comprising a liquid container; a first chamber mounted on said liquid container, wherein said first chamber is formed by a first cylinder and has a first opening; a second chamber formed by a second cylinder and having a second hole, the second cylinder being placed inside said first cylinder; and an element representing a lid interacting with a second chamber to form a storage portion.

Embodiments of the present invention will be described in detail with reference to the accompanying drawings.

In FIG. 1 shows a dispenser 100 of liquid assembled and disassembled according to an embodiment of the present invention.

According to FIG. 1a, the dispenser 100 was assembled (as shown in FIG. 1) to provide a metered supply of liquids. As shown in the figure, the dispenser 100 comprises a liquid container 102 or a liquid source 102 and a dispensing device 104 mounted on top of the dispenser 100. The liquid container 102 may be a glass bottle or plastic bottle or any other known portable liquid container that is a living organism Can easily be lifted for fluid intake directly from the vial.

In FIG. 1b shows the dispenser 100 as well as the disassembled dispenser 104. As shown in the figure, the metering device 104 may be an assembly of a first chamber formed by an outer cylinder 106 or a first cylinder 106, a second chamber formed by an inner cylinder 108 or a second cylinder 108, and an element constituting a cover 110, all of which are installed axially on top of each other in ascending order. As shown in FIG. 1b, the outer cylinder 106 is built-in unequal cylinders, so that the smaller diameter portion 106a is placed inside the container 102, while the upper diameter portion 106b is wrapped around the neck of the container 102 by means of a threaded mechanism. For this purpose, the upper diameter portion 106b of the outer cylinder 106 has an internal thread to match the threaded neck of the container 102, while the neck of the container 102 is twisted externally. However, in another example, the upper diameter portion 106b may also be snapped onto the neck of the container 102.

In addition, the inner cylinder 108, in turn, is placed inside the outer cylinder 106 and also contains parts of unequal diameters. The lower diameter portion 108a of the inner cylinder 108 has a centrally located protrusion 112 (i.e., an extended element) on its lower part for snapping in within an opening 114 located in the center of the lower part of the outer cylinder 106. In other words, the protrusion 112 passes through the opening 114 for the formation of a snap connection. On the other hand, the upper diameter portion 108b or the cylindrical cap 108b of the inner cylinder 108 is adjacent to and lies on the upper diameter portion 106b of the outer cylinder 106. In addition, the outer surface of the upper diameter portion 108b of the inner cylinder 108 is corrugated to provide good grip on the curved surface of the inner cylinder 108 to manually rotate the entire inner cylinder 108. However, this actuation of the inner cylinder 108 does not cause the outer cylinder 106 to rotate due to the snap-fit connection.

In addition, the cover member 110 is mounted on top of the inner cylinder 108 by another snap connection, as shown further in FIG. 2a. The lid member 110 includes a removable shutter covering the opening provided on the upper surface of the lid member 110 and is used to clean the contents of the inner cylinder 108. Accordingly, the lid member 110 interacts with a second chamber or inner cylinder 108 to form a storage portion since the inner cylinder 108 is hollow. More specifically, the storage portion is formed by an integrated hollow cylindrical chamber (i.e., lower diameter portion 108a) with a larger diameter cylindrical cap (i.e., large diameter portion 108b). In addition, for the above cleaning, the shutter of the cap member 110 is manually removable to close or open a hole inside the cap member 110, and typically remains closed until any amount of liquid is dispensed.

Let us turn to FIG. 2 (a), which shows a cross-sectional view of the dispenser 100. The cross-sectional view clearly shows the mutual connection between the various components, such as the threaded connection between the neck of the container 102 and the outer cylinder 106, and the snap connection between the inner 108 and the outer cylinders 106, and a snap connection between the inner cylinder 108 and the cap member 110.

In FIG. 2 (b) illustrates a disassembled assembly of the inner cylinder 108 and the outer cylinder 106. As can be seen from the figure, the outer cylinder 106 and the inner cylinder 108 are provided with corresponding windows or holes 202, 204 extending from curved surfaces to a flat bottom surface. Moreover, the openings 202, 204 on both cylinders 106, 108 are aligned with each other to effectively coincide with each other, resulting in a specific number of turns in a specific direction (e.g., clockwise) into the inner cylinder 108 relative to the outer cylinder 106. However, in another embodiment, the outer cylinder 106 may also be rotatable relative to the inner cylinder 108 to ensure alignment of the holes.

When turned in the other direction (for example, counterclockwise) to the inner cylinder 108, the holes do not coincide with each other, so that the hole on the outer cylinder 106 can most likely be blocked by the curved surface of the inner cylinder 108. To prevent any random development events where the curved surface of the inner cylinder 108 will protrude from the opening of the outer cylinder 106, a flange is provided that is built into the surface of the outer cylinder 106 and separates the hole of the outer cylinder 106 by two halves. The shoulder acts as a structural obstacle to tightly holding the inner cylinder 108 inside the outer cylinder 106, despite the presence of holes on the outer cylinder 106.

In FIG. 3 now depicts the various operating states of the metering device 102 located inside the metering device 100 by means of a cross-sectional view of the container 102. FIG. 3 (a) and FIG. 3 (c) are front cross-sectional views of the dispenser 100, while in FIG. 3 (b) and FIG. 3 (d) is a cross-sectional isometric view of the dispenser 100. The isometric view corresponds to the type of dispenser 100 in an upward direction with the name.

Whereas FIG. 3 (a) and FIG. 3 (b) correspond to the first state, or open state, i.e. both holes 202, 204 coincide with each other, FIG. 3 (c) and FIG. 3 (d) correspond to a second state, or a closed state, i.e. the hole 202 of the outer cylinder 106 is overlapped by the curved surface of the inner cylinder 108. However, each of these states is achievable only by manually rotating the inner cylinder 108 or the outer cylinder 106.

In FIG. 4 shows the interconnection between the upper diameter portion 108b of the inner cylinder 108 and the upper diameter portion 106b of the outer cylinder 106 by means of a cross-sectional view of the inner cylinder 108. In addition, in FIG. 4 also depicts the installation of the cap member 110 onto the upper diameter portion 106b of the inner cylinder 106.

More specifically, in FIG. 4 (a) shows the presence of plugs 402 on the circumferential surface of the outer cylinder 106, i.e. above the circular surface of the upper diameter portion 106b of the outer cylinder 106. In addition, the upper diameter portion 108b of the inner cylinder 108 is also provided with plugs 404 (as shown in the figure) to functionally match the plugs 402 of the outer cylinder 106. The plugs 402, 404 may be small protrusions towering above the surfaces of any of the cylinders 104, 106.

Such coincidence of plugs 402, 404 between the inner cylinder 108 and the outer cylinder 106 limits the rotation of the inner cylinder 108 relative to the outer cylinder 106 or vice versa. In other words, coincidence of traffic jams limits rotation by about 20 ° to 30 ° or provides rotation by no more than a quarter. Moreover, such a limited rotation makes it possible to define the two extreme turning points as an open and closed state, thereby ensuring ease of use, for example, of the inner cylinder 108 as a rotary handle. Whereas a rotation (for example, clockwise) towards one extreme point indicates an OPEN state, i.e. the states described in FIG. 3 (a) and FIG. 3 (b), another rotation (for example, counterclockwise) towards another extreme point leads to a CLOSED state, i.e. the states described in FIG. 3 (c) and FIG. 3 (d). To facilitate such a rotary handle operation, the outer curved surface of the inner cylinder 108 is corrugated for ease of grip. In another example, the outer cylinder 106 may also act as a pivot handle instead of the inner cylinder 108.

In addition, as shown in FIG. 4 (b), an element representing the cap 110 is mounted on top of the inner cylinder 108. Since the inner cylinder 108 is hollow from the inside, the element representing the cap 110 can be snapped onto the inner cylinder 108 and, accordingly, act as a coating for the hollow inner cylinder 108.

Now, according to FIG. 5 shows the operating conditions of the entire dispenser 100. In FIG. 5 (a), the dispenser 100 is shown in an inverted position, which corresponds to the operating state of the dispenser 100. However, the operating state of the dispenser 100 can also be achieved even if the dispenser 100 is not completely turned upside down, but rather turned upside down. In this operating state, the state of the metering device 104 may correspond to any state in FIG. 3 (a) or FIG. 3 (c).

Considering the state of FIG. 3 (a) of the metering device 104 as the default state in the operational state shown in FIG. 5 (a), it can be understood that the holes 204, 202 on the inner 108 and the outer cylinders 106 coincide with each other and, accordingly, lead to the passage of the channel from the container 102 to the inner cylinder 108. Since in the present case the container 102 is upside down, the liquid stored in the container 102 enters the inner cylinder 108 through the outer cylinder 106 due to gravity. Accordingly, it can be understood that the inner cylinder 108, which is also in an inverted position, is completely filled with fluid over a period of time. Accordingly, with this joint, the inner cylinder 108 can be rotated in the form of a rotary knob to achieve a CLOSED state, as shown in FIG. 3 (c). Accordingly, as long as the collected fluid remains inside the inner cylinder 108, the channel between the container 102 and the metering device 104 closes due to this rotation.

In addition, as shown in FIG. 5 (a), the state of the metering device 104 may more closely correspond to the state of FIG. 3 (c) than the state depicted in FIG. 3 (a). In this scenario, since there is no liquid flow down from the container 102 to the inner cylinder 108 even when the dispenser 100 is turned over, the state shown in FIG. 3 (a) should be achieved by turning the inner cylinder 108 to create a fluid flow. Accordingly, the liquid fills the inner cylinder 108 in a few seconds, for example, 2-3 seconds or more, depending on whether the dispenser 100 is completely turned upside down or partially. In addition, for example, after 5-6 seconds, when there is a high probability that the inner cylinder 108 will be completely full, the inner cylinder 108 can be rotated again to return to the state, as shown in FIG. 3 (c).

Then, the shutter of the element, which is the cover 110, can be opened to extract the amount of liquid collected in the inner cylinder 108. To dispense after opening the shutter, the dispenser 100 can be held in a slightly inverted position to dispense the liquid at the optimum flow rate. It can be understood that achieving the state as shown in FIG. 3 (c) is a prerequisite for dispensing fluid from the inner cylinder 108, and if such a requirement is not met, not only the contents of the inner cylinder 108 will flow, but also the contents of the container 102, and the purpose of the metered supply will seem impossible.

As shown in FIG. 5 (b), dispenser 100 is returned to its normal vertical position. As can be understood, this position of the dispenser 100 prevents any fluid flow from the container 102 to the inner cylinder 108, regardless of the conditions depicted in FIG. 3. The present upright position may also be useful if it is necessary to empty the pre-filled inner cylinder 108 by draining the contents of the inner cylinder 108 back into the container 102. Accordingly, for this purpose, the inner cylinder 108 can be rotated to achieve a state as shown in FIG. 3 (a) or FIG. 3 (b).

In General, as a result of the implementation of the present invention, the dispenser 100 is provided for the supply of a fixed or exact dose of all types of liquid products, liquid drugs for oral administration and similar liquid consumables. In addition, the dosing device 104, forming part of the dispenser 100, acts as a substitute for the existing cap of the vial of the liquid container (or vial), and almost every type of portable liquid container having a neck can be upgraded by the dosing device 104.

At least by virtue of the foregoing embodiments, the present invention provides a metering device 104 having substantially fewer components than conventional liquid metering devices. In addition, the components in the metering device 104 do not require any energy source (for example, the action of a gas, spring or piston) for their functionality and, accordingly, are not only cheap, but also durable.

In addition, the present invention also eliminates the need for additional utensils for administering a measured dose of a liquid drug. This is due to the fact that a dosed amount of a liquid dose (such as that collected in the inner cylinder 108) can be directly consumed by a living organism without contact of the liquid with the outer dishes, thereby minimizing the likelihood of contamination or environmental influences on highly sensitive liquids.

While specific phrases are used to describe the disclosure, any restrictions arising for the same reason are not provided. As is obvious to a person skilled in the art, various working modifications can be applied to the method for implementing the idea of the invention as described herein.
