Dry ice vaporizing device and method

Abstract

A dry ice vaporizing device includes: a container having a vapor permeable surface and a closeable entrance configured to be locked closed, an external implement configured to unlock the closeable entrance, and dry ice located inside the container. The vapor permeable surface includes a plurality of holes each having a hole dimension less than approximately 4 mm. The container is configured, when the closeable entrance is locked closed, to prevent the passage of dry ice pieces having dimensions larger than the hole dimension.

1 . A dry ice vaporizing device, comprising:
 a container comprising a vapor permeable surface and a closeable entrance configured to be locked closed;   an external implement configured to unlock the closeable entrance; and   dry ice located inside the container,   wherein the vapor permeable surface comprises a plurality of holes each having a hole dimension less than approximately 4 mm, and   wherein the container is configured, when the closeable entrance is locked closed, to prevent the passage of dry ice pieces having dimensions larger than the hole dimension.   
   
   
       2 . The dry ice vaporizing device as claimed in  claim 1 , wherein the container comprises a snap buckle comprising a male hook lockable to a female receiver. 
   
   
       3 . The dry ice vaporizing device as claimed in  claim 2 , wherein the external implement comprises an unlocking block comprising:
 a hitch configured to contact the male hook to thereby unlock the closeable entrance; and   a splitter configured to open the closeable entrance.   
   
   
       4 . The dry ice vaporizing device as claimed in  claim 1 , further comprising a handle connected to the container, the handle having a length not shorter than a longest dimension of the container. 
   
   
       5 . The dry ice vaporizing device as claimed in  claim 4 , wherein the handle comprises a hollow tube configured to allow liquid to pass through. 
   
   
       6 . The dry ice vaporizing device as claimed in  claim 1 , wherein the container is substantially cylindrical and comprises:
 a first semicylinder comprising a rounded portion and two end portions;   a second semicylinder comprising a rounded portion and two end portions, the second semicylinder connectable to the first semicylinder so that when the first and second semicylinders are mated they substantially form a cylinder; and   a hinge connecting the first and second semicylinders at ends of the first and second semicylinders,   wherein at least one of the first and second semicylinders comprises the vapor permeable surface, and   wherein the first and second semicylinders are configured to open and close relative to each other via the hinge.   
   
   
       7 . The dry ice vaporizing device as claimed in  claim 6 , further comprising a handle connected to the container, the handle having a length not shorter than a longest dimension of the container, wherein the handle comprises a hollow tube configured to allow liquid to pass through. 
   
   
       8 . A method of using dry ice, comprising:
 providing the dry ice vaporizing device as claimed in  claim 1 ;   closing and locking the closeable entrance; and   submerging the device in a fluid.   
   
   
       9 . A dry ice vaporizing device, comprising:
 a container comprising a vapor permeable surface and a closeable entrance configured to be locked closed;   a handle connected to the container, the handle having a length not shorter than a longest dimension of the container; and   dry ice located inside the container,   wherein the vapor permeable surface comprises a plurality of holes each having a hole dimension less than approximately 4 mm, and   wherein the container is configured, when the closeable entrance is locked closed, to prevent the passage of dry ice pieces having dimensions larger than the hole dimension.   
   
   
       10 . The dry ice vaporizing device as claimed in  claim 9 , wherein the handle comprises a hollow tube configured to allow liquid to pass through. 
   
   
       11 . The dry ice vaporizing device as claimed in  claim 9 , wherein the container comprises a snap buckle comprising a male hook lockable to a female receiver. 
   
   
       12 . A method of using dry ice, comprising:
 providing the dry ice vaporizing device as claimed in  claim 9 ;   closing and locking the closeable entrance; and   submerging the device in a fluid.   
   
   
       13 . A dry ice vaporizing device, comprising:
 a) a substantially cylindrical container comprising:
 a first semicylinder comprising a rounded portion and two end portions; 
 a second semicylinder comprising a rounded portion and two end portions, the second semicylinder connectable to the first semicylinder so that when the first and second semicylinders are mated they substantially form a cylinder; and 
 a hinge connecting the first and second semicylinders at ends of the first and second semicylinders; and 
   b) dry ice located inside the container,
 wherein at least one of the first and second semicylinders comprises a vapor permeable surface comprising a plurality of holes each having a hole dimension less than approximately 4 mm, 
 wherein the first and second semicylinders are configured to open and close relative to each other via the hinge, 
 wherein the substantially cylindrical container is configured to be locked closed, and 
 wherein the substantially cylindrical container is configured, when it is locked closed, to prevent the passage of dry ice pieces having dimensions larger than the hole dimension. 
   
   
   
       14 . The dry ice vaporizing device as claimed in  claim 13 , wherein the substantially cylindrical container comprises a snap buckle, whereby the second semicylinder comprises a female receiver and the first semicylinder comprises a male hook lockable to the female receiver. 
   
   
       15 . The dry ice vaporizing device as claimed in  claim 13 , further comprising a handle connected to the substantially cylindrical container, the handle having a length not shorter than a longest dimension of the substantially cylindrical container. 
   
   
       16 . The dry ice vaporizing device as claimed in  claim 15 , wherein the handle comprises a hollow tube configured to allow liquid to pass through. 
   
   
       17 . A method of using dry ice, comprising:
 providing the dry ice vaporizing device as claimed in  claim 13 ;   closing and locking the substantially cylindrical container; and   submerging the device in a fluid.
