Abstract

A dual syringe adapter for attachment to a pair of side-by-side syringes includes three interconnected portions. A first portion is configured so as to snap onto a plunger head portion of each syringe so as to connect the pair of syringes and maintain plunger movement in unison. A second portion of the adapter is configured so as to snap onto a syringe body of each syringe to help maintain the connection of the two syringes. The third interconnected portion is positioned between the first and second portions and when connected prevents relative movement of the plungers into the syringe bodies. Weakened sections allow the connecting portion to be severed from the first and second portions thereby allowing plunger movement into the syringe bodies. Once severed, the connecting portion is secured to syringe tips for dispensing a mixed composition.

Claims (16)

1. A dual syringe adapter for attachment to and use with a pair of side-by-side syringes, said dual syringe adapter comprising:

a unitary structure having three initially interconnected portions including a plunger head portion, a syringe body portion and a separable connecting portion positioned between the plunger head portion and the syringe body portion, said separable connecting portion including a pair of tip-receiving sleeves and a flow-dispensing cavity, wherein in its initial unseparated condition, the separable connecting portion functions as a blocking element and prevents any significant reduction in the spacing between said plunger head portion and said syringe body portion and when separated from said unitary structure, said separable connecting portion is constructed and arranged to fit onto the dispensing tips of the side-by-side syringes such that any material dispensed from either syringe flows into said dispensing cavity.

2. In combination:

a first syringe including a hollow syringe body formed with a dispensing tip at one end and an opening at the opposite end, and a plunger inserted into said syringe body, said plunger including a plunger head; and

a second syringe having a hollow syringe body formed with a dispensing tip at one end and an opening at the opposite end, and a plunger inserted into said syringe body, said plunger including a plunger head; and

a dual syringe adapter for attachment to and use with said first and second syringes, said dual syringe adapter comprising:

a unitary structure having three initially interconnected portions including a plunger head portion, a syringe body portion and a separable connecting portion positioned between the plunger head portion and the syringe body portion, said separable connecting portion including a pair of tip-receiving sleeves and a flow-dispensing cavity, wherein in its initial unseparated condition, the separable connecting portion functions as a blocking element and prevents any significant reduction in the spacing between said plunger head portion and said syringe body portion and when separated from said unitary structure, said separable connecting portion is constructed and arranged to fit onto the dispensing tips of the side-by-side syringes such that any material dispensed from either syringe flows into said dispensing cavity.

3. A method of controlling the dispensing of material contents from a pair of side-by-side syringes, said method comprising the following steps:

providing a syringe that includes a first material for dispensing, the first syringe including a hollow body, a plunger moveable in said hollow body and a dispensing tip; and

providing a second syringe that includes a second material for dispensing, said second syringe including a hollow body, a plunger moveable in said hollow body and a dispensing tip;

providing a dual syringe adapter constructed and arranged as a unitary structure having three initially connected portions including a first portion, a second portion and an intermediate connecting portion;

attaching said first portion to the plunger of said first syringe and to the plunger of said second syringe;

attaching said second portion to the hollow body of said first syringe and to the hollow body of said second syringe, wherein said connecting portion prevents any significant inward relative motion of said syringe plungers into said corresponding syringe bodies; and

manually severing said connecting portion from said first portion and manually severing said connecting portion from said second portion so as to enable inward movement of each plunger into its corresponding syringe body.

4. The method of claim 3 which further includes the step of assembling said severed connecting portion onto said pair of syringe tips, said connecting portion including a material cavity constructed and arranged to receive material from each syringe.

5. The method of claim 4 which further includes the step of pushing each of said plungers into its corresponding hollow body so as to dispense a portion of the material content in each syringe into said material cavity such that the two material contents exit from said material cavity as a two-material composition.
