Refill container for refillable electronic vaping devices

Abstract

A container for separately containing pre-vapor formulation ingredients prior to filling a reservoir of an electronic wiping device includes a container body having a first opening, a first compartment in the container body, a second compartment in the container body, a first seal between the first compartment and the second compartment, and a lid configured to cover the opening. The first compartment contains at least a first ingredient. The second compartment contains at least a second ingredient. The first seal is a frangible seal and is substantially impermeable. The lid is connected to the first seal.

We claim: 
     
         1 . A container for separately containing pre-vapor formulation ingredients prior to filling a reservoir of an electronic vaping device, the container comprising:
 a container body having a first opening;   a first compartment in the container body, the first compartment containing at least a first ingredient;   a second compartment in the container body, the second compartment containing at least a second ingredient;   a first seal between the first compartment and the second compartment, the first seal being substantially impermeable; and   a lid configured to cover the opening, the lid connected to the first seal, such that removal of the lid breaks the first seal.   
     
     
         2 . The container of  claim 1 , wherein the first seal is formed of at least one of a plastic and a metal foil coated with an inert substance. 
     
     
         3 . The container of  claim 2 , wherein the container and the first seal are formed of the same material. 
     
     
         4 . The container of  claim 2 , wherein the first seal is about 50 microns to about 1000 microns thick. 
     
     
         5 . The container of  claim 1 , further comprising:
 a third compartment in the container body, the third compartment containing at least a third ingredient; and   a second seal separating the third compartment from at least one of the first compartment and the second compartment, the second seal being substantially impermeable.   
     
     
         6 . The container of  claim 5 , wherein the second seal is formed of the same material as the first seal and removal of the lid breaks the second seal. 
     
     
         7 . The container of  claim 5 , wherein the second seal is connected to the first seal. 
     
     
         8 . The container of  claim 6 , wherein the second seal is coated with an inert substance. 
     
     
         9 . The container of  claim 1 , wherein at least one of the container body, the lid, and the first seal is coated with an inert substance. 
     
     
         10 . The container of  claim 1 , wherein the lid is a screw-top lid. 
     
     
         11 . The container of  claim 1 , wherein the first compartment contains at least one of nicotine and a flavorant and the second compartment contains at least one of an aerosol former, an acid, and water. 
     
     
         12 . The container of  claim 1 , wherein the first seal extends substantially horizontally between the first compartment and the second compartment. 
     
     
         13 . The container of  claim 12 , further comprising:
 a seal connector is attached to the first seal and attached to the lid, such that when the lid is removed from the container, the seal connector pulls the first seal to break the first seal.   
     
     
         14 . The container of  claim 1 , wherein the first seal extends substantially vertically between the first compartment and the second compartment. 
     
     
         15 . A container for separately containing pre-vapor formulation ingredients prior to filling a reservoir of an electronic wiping device, the container comprising:
 a container body having an opening therein;   a first compartment in the container body, the first compartment containing at least a first ingredient;   a lid covering the opening; and   a dropper extending from the lid into the first compartment, the dropper containing at least a second ingredient, the dropper including a dropper opening, the dropper opening covered with a covering, the covering being removable and substantially impermeable.   
     
     
         16 . The container of  claim 15 , wherein the dropper includes measurement markings on a side thereof, the measurement markings including indicia indicating amounts of the second ingredient. 
     
     
         17 . The container of  claim 15 , wherein the covering is formed of at least one of a plastic and a metal foil coated with an inert substance. 
     
     
         18 . The container of  claim 15 , further comprising;
 a second compartment in the container body, the second compartment containing at least a third ingredient; and   a first seal between the first compartment and the second compartment, the first seal being impermeable, and the first seal being connected to at least one of the lid and the dropper, such that the first seal is broken when the lid is removed from the container.   
     
     
         19 . A method of increasing shelf-life of a pre-vapor formulation, the method comprising:
 storing at least a first ingredient in a first compartment of a container; and   storing at least a second ingredient in a second compartment of the container, the first compartment separated from the second compartment by a first seal, the first seal being substantially impermeable, the first seal attached to a container lid, and the first seal configured to be removed upon opening of the container.
