Description

SPECIFICATION Metering pen for delivering a metered amount of fluid or loose substances The present invention relates to a metering pen for delivering a metered amount of fluid or loose substances, in particular in powder form, from a barrel.
As it is known, pharmaceutical products and the like are frequently used in the form of tablets.
On the other hand, the mentioned tablets do not offer the possibility of metering in the desired way the active substance contained in said tablets. Thus, for example, by using two or three sweetening tablets, is hardly possible to obtain the desired sweetness for a single user.
Accordingly, the task of the present invention is to provide such a device for delivering metered amounts of fluid or loose substance from a barrel, which is effective to afford the possibility of precisely metering the substance to be supplied.
According to the invention, that task is achieved by a metering pen for delivering metered amounts of fluid or loose substances, in particular in a powder form, from a barrel, characterized in that: a. The barrel is designed as a tubular elongated vessel and is provided, on its bottom front surface, with a delivery opening; b. In said vessel there is arranged, in a shiftable way, a delivery rod projecting from said vessel on the top front surface or face thereof; c. The delivery rod is preloaded towards the top front face of said vessel, by means of an encompassing coil spring; d. The lower end portion of said rod is shaped as a closure small piston effective to normally close the delivery or supply opening; e.At the portion whereof adjoining the closure small piston, at the top, the delivery rod is provided with an annular groove, which may be brought into the delivery opening, by displacing said rod, in such a way that said opening is only partially closed and the amount of substance contained between said rod and annular groove may be ejected from the delivery opening.
The metering pen according to the invention will become more apparent thereinafter from the following detailed description of a preferred embodiment of said metering pen, with reference to the accompanying drawings where: Figure 1 is a partially broken away sectional view of a metering device, according to the invention, in the form of a ball-pen or the like; Figure 2 is a cross-section view of the subject pen as taken along the line 2-2 of Figure 1; Figure 3 is an enlarged detailed view of the device according to the invention, taken at the circle X of Figure 1, the metering device being shown in a first operating position; Figure 4 is a view like to Figure 3, the metering device being shown in a second operating position; and Figure 5 is a detailed view therein there is shown an adapter for filling the metering device according to the invention.
Figure 1 illustrates a tubular elongated vessel 1, which is narrowed at the bottom and is in the form of a writing tool, for example a ball-pen or the like.
A resiiient small spring 2 is provided for affixing the vessel 1 to a pocket of a jacket or the like.
More specifically, the vessel 1 comprises two portions, that is a lower portion 3 and a top portion 4, which, for example, may be made of a suitable plastics material.
The bottom or lower portion 3 is closed by a closure element 5, for example made of a metal, and provided with a center hole.
The top portion 4 is shaped as a threadable cap, and may be screwed on the bottom portion 3, at the region separating the two portions 3 and 4 there being provided an ornamental ring member, also made of a metal, which is like to the ornamental ring member provided on a writing tool.
On its lower front face, the portion 3 of said vessel 1 is provided with a delivery opening 7, which is shaped as a short cylindrical-circular channel.
Inside said vessel 1 there is arranged a movable delivery rod 8, preferably made.of a metal material and having a circular cross-section, which passes through the center hole of the closure element 5 and projects from the top front face of said vessel 1 , with an end portion 9 having a greater diameter.
At its top end portion, the rod 8 is provided with an enlarged diameter collar, effective to prevent said rod 8 from exiting the top front face of the vessel.
On that collar member there is supported an end portion of a pressing coil spring 10, encompassing the rod 1 and the other end portion whereof is supported on said closure element 5.
At its lower or bottom end portion, the delivery rod 8 is provided with an annular groove, which, in the illustrated embodiment, is shaped as a double cone.
After the mentioned annular groove 12 there is located the end portion of the delivery rod 8, which forms a closure small piston 1 3. The height of said closure piston 1 3 corresponds, as it is clearly shown in Figure 1 , to the height of the cylindrical-circular delivery opening 7.
In the position shown in Figure 1, the delivery opening 7 is tight closed by said closure piston 1 3.
In the bottom portion 3 of the vessel 1 there is contained a fluid or loose substance or material 14, for example in the form of a powder material or of a paste material. The bottom portion of the vessel 1 is preferably made from a clear plastics material, thereby it will be very easy to know the filling condition of the vessel.
Accordingly the bottom portion 3 forms the barrel proper for the material to be delivered.
In Figure 1 , the delivery opening 7 is tight closed by the end portion of the delivery rod 8, forming the mentioned closure small piston 13.
The coil spring 10 holds the rod 8 in the shown position. If on the end portion 9 of the driving rod a pressure is applied, for example by a finger, against the force of the spring 10, then the end portion of the rod 8 wil be displaced at first to the positon shown in Figure 3.
The substance which in Figure 1 is arranged at the annular groove 12 will be displaced downwardly and will be enclosed between the annular groove and the inner wall of the delivery opening 7.
The enclosed substance amount will be precisely determined by the volume between the annular groove 12 and the inner wall of the delivery opening 7.
By further displacing downwardly the rod 8, the position illustrated in Figure 4 is obtained, therein the enclosed substance 14 will exit the vessel in a precisely metered amount.
By disengaging the driving rod 8, the latter returns to the position shown in Figure 1 thereby, if desired, a new metered amount of substance may be again delivered through a new operation.
Thus, by correspondingly making and designing the annular groove 12, the metering of the substance to be delivered may be precisely adjusted, in a very fine way.
It shouid be noted that the driving rod 8 has an even diameter with the exception of the region thereat the annular groove 12 is formed and of the region of its-top end portion 9, projecting from the vessel 1. In particular, the closure piston 1 3 has the same diameter as the remaining portion of the rod 8.
That diameter is equal to the inner diameter of the delivery opening 7. Thus it will be possible, as it is shown in Figure 4, to separate a precisely metered amount of the contained substance and, as it is shown in Figure 4, it is also possible to prevent the substance 14 from being delivered in an excess amount, since the portion of the rod 8 adjoining the annular groove 12 has the same diameter as the small piston 1 3.
The above disclosed device is in particular effective to supply or deliver in a precise and fine way medicinal substances in the powder or fluid form. It should also be noted that the disclosed device may also be used for delivering any other fluid or loose substance or material.
In particular, the vessel 1 is filled with the new substance in the following way: the top portion 4 af the vessel is screwed off from the lower portion 3 of the vessel, and the driving rod 1 is withdrawn from the delivery opening 7, as it shown in Figure 5. On the lower end of the portion 3 of the vessel, an adapter 1 5 is applied, having, for example, a funnel shape, and the device is rotated through 1800, in such a way as to cause the adapter 1 5 to face upwardly, with its filling opening 1 6. Then, from a larger vessel, the desired substance may be introduced through the delivery opening 7 formed in the lower portion 3 of the vessel, with the possibility of directly inserting into the adapter 1 5 the port of the filling vessel.It will be obvious that the amount of fluid substance which may be introduced into the lower portion of the vessel will depend on the annular gap between the driving rod 8 and the inner wall of the vessel portion 3.
More specifically, the outer diameter of the driving rod 8 will be designed depending on the inner diameter of the portion 3 of the vessel, and, possibly, it will have a small value. It should be pointed out that it is possible to select the mentioned diameters in such a way as to afford the possibility of introduing into the portion 3 of the vessel an amount of fluid or loose substance corresponding to about 100 conventional sweeting substance tablets.
