Dispenser with twist lock fitting

Abstract

A dispenser for dispensing a unit measure of a product includes a twist-locking mechanism. The twist-locking mechanism included on the dispenser engages a twist-locking mechanism on a dispensing accessory device, locking the accessory device to the dispenser. The disposable dispenser may include a cap frangibly coupled to the housing of the dispenser, the cap to be removed when dispensing the product. The disposable dispenser may be formed of a single material that is suitable for a blow-fill-seal process.

         16 . A method of manufacturing a unit-measure dispenser, the method comprising:
 heating a first material to a first temperature;   enclosing the first material in a mold, the mold comprising a shape to form a housing including a first body, a reservoir for containing a unit-measure of a product to be dispensed, an outlet disposed on the reservoir for dispensing the product from the reservoir, and a twist-locking mechanism disposed on the housing, the twist-locking mechanism configured to engage an opposite gender twist-locking mechanism disposed on an accessory device and to mate the accessory device to the outlet of the reservoir;   inflating the first material in the mold to form the first body;   cooling the first body formed of the first material;   filling the reservoir of the first body with the unit-measure of the product to be dispensed; and   sealing the first body to prevent the product from escaping the first body prior to use.   
     
     
         17 . (canceled) 
     
     
         18 . The method of  claim 16 , wherein the accessory device comprises at least one of: a needle, a spoon, a static mixer, a barb, a tube, a dropper, or an applicator. 
     
     
         19 . The method of  claim 16 , the mold further including a shape to form a cap frangibly coupled to the first body, wherein the cap seals the outlet to prevent the product from escaping the reservoir through the outlet prior to use. 
     
     
         20 . The method of  claim 16 , the mold further including a shape to form another reservoir for containing a unit-measure of another product to be dispensed, and an outlet on the other reservoir such that the product and the other product can be dispensed concurrently through the outlet;
 the method further comprising filling the other reservoir of the first body with a unit-measure of the other product to be dispensed; and   sealing the first body to prevent the other product from escaping the first body prior to use.   
     
     
         21 . The method of  claim 16 , wherein the twist-locking mechanism disposed on the housing is a female luer fitting configured to engage a male twist-locking mechanism disposed on the accessory device. 
     
     
         22 . The method of  claim 21 , wherein the female luer fitting includes external threads. 
     
     
         23 . The method of  claim 22 , wherein the outlet is sized to receive a portion of the accessory device when the accessory device is engaged by the twist-locking mechanism disposed on the housing. 
     
     
         24 . The method of  claim 16 , wherein the twist-locking mechanism disposed on the housing is a male luer fitting configured to engage a female twist-locking mechanism disposed on the accessory device. 
     
     
         25 . The method of  claim 24 , wherein the male luer fitting includes internal threads. 
     
     
         26 . The dispenser of  claim 24 , wherein the outlet comprises mating surfaces configured to mate with accessory device mating surfaces, the mating surfaces including a cylindrical peripheral surface and an abutting axial end surface. 
     
     
         27 . The method of  claim 16 , wherein the first material is a polymer resin selected from the group consisting of polyethylene, polypropylene and ethyl vinyl alcohol. 
     
     
         28 . The method of  claim 16 , wherein a mandrel is used to fill the reservoir with the product. 
     
     
         29 . A method of manufacturing a unit-measure dispenser, the method comprising:
 heating a first material to a first temperature, wherein the first material is selected from polypropylene, polyethylene or ethyl vinyl copolymer;   enclosing the first material in a mold, the mold comprising a shape to form a housing including a reservoir for containing a unit-measure of a product to be dispensed, an outlet disposed on the reservoir for dispensing the product from the reservoir, and a twist-locking mechanism disposed on the housing and integral with the outlet;   inflating the first material in the mold to form the housing;   cooling the housing formed of the first material;   filling the reservoir with the unit-measure of the product to be dispensed; and   sealing the housing to prevent the product from escaping the reservoir prior to use.   
     
     
         30 . The method of  claim 29 , wherein the twist-locking mechanism disposed on the housing is a female luer fitting with external threads, and configured to engage a male twist-locking mechanism disposed on an accessory device. 
     
     
         31 . The method of  claim 29 , wherein the twist-locking mechanism disposed on the housing is a male luer fitting with internal threads configured to engage a female twist-locking mechanism disposed on an accessory device. 
     
     
         32 . The method of  claim 29 , wherein a mandrel is used to fill the reservoir with the product. 
     
     
         33 . A unit-measure dispenser of a product contained in a reservoir of the dispenser, the dispenser prepared by a process comprising:
 heating a first material to a first temperature;   enclosing the first material in a mold, the mold comprising a shape to form a housing including a body, the reservoir for containing a unit-measure of the product to be dispensed, an outlet disposed on the reservoir for dispensing the product from the reservoir, and a twist-locking mechanism disposed on a housing and integral with the outlet;   inflating the first material in the mold to form the body;   cooling the body formed of the first material;   filling the reservoir of the body with the unit-measure of the product to be dispensed; and   sealing the body to prevent the product from escaping the reservoir prior to use.   
     
     
         34 . The method of  claim 33 , wherein the twist-locking mechanism disposed on the housing is a female luer fitting with external threads, and configured to engage a male twist-locking mechanism disposed on an accessory device. 
     
     
         35 . The method of  claim 33 , wherein the twist-locking mechanism disposed on the housing is a male luer fitting with internal threads configured to engage a female twist-locking mechanism disposed on an accessory device.
