LIQUID MEDICAMENT DISPENSER

A liquid medicament dispenser having a tubular barrel extending from a plunger end to a cap end having a cap opening and without a washer. The present invention includes a plunger dimensioned and adapted to hermetically engage the inner circumference of the tubular barrel so that as it moves between a fully compacted condition and a partially compacted condition pressure develops therein, thereby urging a liquid medicament in or out through the cap end.

BACKGROUND OF THE INVENTION

The present invention relates to medicinal applicators and, more particularly, a liquid medicament dispenser.

Current oral syringes consist of a barrel, plunger and silicone washer to function as a liquid medicament dispenser. Silicone washers, however, can get dirty and accumulate unhealthy debris and pathogens.

As can be seen, there is a need for a washer-less liquid medicament dispenser comprising an only two-piece assembly: barrel and plunger, requiring less time and cost to assemble, maintain, clean and operate as a functioning oral syringe.

SUMMARY OF THE INVENTION

In one aspect of the present invention, liquid medicament dispenser without a washer includes the following: a tubular barrel extending from a plunger end to a cap end having a cap opening; and a plunger dimensioned to hermetically engage an inner circumference of the tubular barrel so that as the plunger moves between a compacted condition and a partially compacted condition pressure develops therein, thereby urging a flow out through the tubular barrel.

In another aspect of the present invention, liquid medicament dispenser without a washer includes the following: a tubular barrel extending from a plunger end to a cap end having a cap opening; a plunger dimensioned to hermetically engage an inner circumference of the tubular barrel so that as the plunger moves between a compacted condition and a partially compacted condition pressure develops therein, thereby urging a flow out through the tubular barrel; a cap dimensioned to engage the cap end in a sealed configuration, preventing said flow; and the cap being movable between the sealed configuration and an unsealed configuration; and the cap end is asymmetrically disposed along the cap end, wherein the tubular barrel defines a volumetric capacity ranging between one and ten milliliters.

DETAILED DESCRIPTION OF THE INVENTION

Broadly, an embodiment of the present invention provides a liquid medicament dispenser having a tubular barrel extending from a plunger end to a cap end having a cap opening and without a washer. The present invention includes a plunger dimensioned and adapted to hermetically engage the inner circumference of the tubular barrel so that as it moves between a fully compacted condition and a partially compacted condition pressure develops therein, thereby urging a liquid medicament in or out through the cap end.

Referring now toFIGS. 1 through 20, the present invention may include a liquid medicament dispenser10,20,30,40, or50having a tubular barrel,12,22,32,42or52, respectfully, extending from a plunger end13,23,33,43or53to a cap end15,25,35,45or55, and without a washer. The present invention may include a plunger14,24,34,44, or54dimensioned and adapted to hermetically engage the inner circumference of the tubular barrel,12,22,32,42or52, so that as it moves between a fully compacted condition (seeFIGS. 3, 7, 11, 15, 19) and a partially compacted condition (seeFIGS. 4, 8, 12, 16, 20) pressure develops in the tubular barrel,12,22,32,42or52, thereby urging a liquid (not shown) therein through the cap end15,25,35,45or55, and similarly urging the same liquid out of the cap end15,25,35,45or55when the plunger14,24,34,44, or54is moved toward the fully compact condition. The liquid medicament dispenser10,20,30,40, or50may provide a plurality of embodiments, each having different volumetric capacities of their respective tubular barrel,12,22,32,42or52; for example, the liquid medicament dispenser10may be associated with a 1 mL volumetric capacity; the liquid medicament dispenser20may be associated with a 3 mL volumetric capacity, the liquid medicament dispenser30may be associated with a 5 mL volumetric capacity, the liquid medicament dispenser40may be associated with a 10 mL volumetric capacity, and the liquid medicament dispenser50may be associated with a 20 mL volumetric capacity. The present invention may include a cap16,26,36,46, or56, respectively, dimensioned and adapted to removably seal any of the respective cap ends15,25,35,45, or55, each having a cap opening, as illustrated in the Figures, whereby the present invention can be positioned in a sealed (with cap16,26,36,46, or56engaging the cap opening) and an unsealed configuration.

A method of using the present invention may include the following. The liquid medicament dispenser10,20,30,40, or50disclosed above may be provided. By moving the respective plunger14,24,34,44, or54from the fully compacted to the partially compacted condition, when the present invention is positioned in the unsealed configuration, a liquid medicament may be selectively drawn into the respective tubular barrel,12,22,32,42or52through the respective cap end15,25,35,45, or55for subsequent dispensing through the same by moving the respective plunger14,24,34,44, or54back toward the fully compacted condition. Prior to dispensing or storage, the present invention can be positioned in the sealed configuration.
