| 摘要 | An intrinsically non-explosive liquid constituent of an explosive composition is contained within a can. The can is located inside of a plastic bottle. In the field an intrinsically non-explosive solid constituent of the explosive composition is poured from a separate container into a space in the bottle above the cam. The user presses down on the capped top of the bottle to move a downwardly projecting cutter carried by an upper portion of the bottle downwardly and through the top of the can. Following cutting the bottle is turned upside down and/or shaken to cause a mixing of the two constituents of the explosive composition. The resulting explosive is a liquid which can be poured from the bottle and then detonated by a conventional detonator, or detonated while still in the bottle. | ||||||
| 权利要求 | 2. The field-mix explosive package of claim 1, wherein the chamber formed by said inner wall means is a rigid can, and said can includes a lower rim bead and said package includes means connecting said rim bead to said outer wall means. 3. The field-mix explosive package of claim 1, wherein said punch is an elongated member having a lower end portion cut for progressive entry into the said first wall means upon movement towards said first wall means. 4. The field-mix package of claim 3, wherein said punch has a curved cutting edge which starts from a generally pointed leading end and curves both laterally and axially away from said leading end, on both sides thereof. 5. The field-mix package of claim 1, wherein said outer wall means forms a relatively small diameter tubular neck in the region of the access opening, and said punch includes an upper end portion including means for securing it to said neck portion. 6. The field-mix package of claim 5, wherein said punch also includes upwardly extending means for engaging the opening of another container, and serving to locate the opening of such other container in substantial axial alignment with said access opening. 7. The field-mix explosive package of claim 5, wherein the chamber formed by said inner wall means is a rigid can, and said can includes a lower rim bead and said package includes means connecting said rim bead to said outer wall means. 8. The field-mix explosive package of claim 5, wherein said punch is an elongated member having a lower end portion cut for progressive entry into the said first wall means upon movement towards said first wall means. 9. The field-mix package of claim 8, wherein said punch has a curved cutting edge which starts from a generally pointed leading end and curves both laterally and axially away from said leading end, on both sides thereof. 10. The field-mix explosive package of claim 1, wherein the outer wall means is made from a light transmitting plastic material and a dye material is present in the mixing space, causing the two constituents to assume a color upon mixing, whereby the user can tell when mixing has occurred by viewing the color through said outer wall means. 11. The field-mix package of claim 1, wherein said inner wall means is initially a hermetically sealed can having a rim bead at its lower end, said outer wall means surrounds the can and said bead, and includes a first retainer ring having a lip defining and opening large enough to receive the can but not pass the rim bead, and a second retainer member which underlies the can and holds it within the outer wall means, and wherein the two retainer members are firmly secured to the outer wall means. 12. A method of handling and mixing an explosive prior to its use, comprising: locating an intrinsically non-explosive first constituent of an explosive composition within a sealed first container; positioning said first container inside of a larger second container such that a mixing space exists in said second container above said first container; anchoring a cutting tool to an upper portion of said second container, which cutting tool is of a type having a cutting edge at its lower end and is of such a length that the cutting edge is normally spaced above the first container; transporting said first constituent in said first and second container assembly; transporting an intrinsically non-explosive second constituent of the explosive composition in a third container; preparatory to use, pouring said second constituent from said third container into the space in the second container above The first container; closing said second container; forcing the top of said second container downwardly to move the cutting edge of said cutting tool through said first container; and repositioning said second container as necessary to cause a mixing of the first and second constituents. 13. A field-mix explosive package, comprising: inner wall means forming a chamber for an intrinsically non-explosive first constituent of an explosive composition; outer wall means surrounding said inner wall means and extending above said inner wall means to form a container which includes a space therein above the chamber for receiving an intrinsically non-explosive second constituent of the explosive composition, said outer wall means terminating above said chamber in an access opening for said container; a closure for said access opening; punch means including an elongated handle extending upwardly from said container along the inside portion of said outer wall means in its extent above the container, and a punch portion connected to the lower end of said handle and extending over a portion of the container; said outer wall means being readily bendable by a lateral squeezing action thereon in the vicinity of said handle, so that such a squeezing action can be used to move the handle of the punch means laterally inwardly, causing a downward swinging movement of the punch portion through the container, providing an opening in the container and permitting mixing of the two constituents within the confines of the outer wall means to form the explosive composition. 14. The field-mix explosive package of claim 13, wherein the chamber formed by said inner wall means is a rigid can, and said can includes an upper closure, and said punch portion is a pointed member which prior to use extends over the upper closure of the can, and said punch portion is rigidly connected to the lower end portion of the handle so that swinging movement of the handle will cause a swinging movement of the punch portion. 15. A field-mix explosive package, comprising: inner wall means forming a chamber for an intrinsically non-explosive first constituent of an explosive composition; outer wall means surrounding said inner wall means and extending above said inner wall means to form a container which includes a space therein above the chamber for receiving an intrinsically non-explosive second constituent of the explosive composition, said outer wall means terminating above said chamber in an access opening for said container; a closure for said access opening; punch means within the confines of the outer wall means and positioned in close proximity to said container, said punch means functioning upon a collapsing force applied to some portion of the outer wall means to pierce through a portion of the container, so that the constituent within said container can be released therefrom within the confines of the outer wall means to mix with the other constituent to form the explosive composition. 16. The field-mix explosive package of claim 15, in combination with a relatively rigid packing sleeve which surrounds at least that portion of the outer wall means which is forced inwardly to move the punch means through a portion of the container, said packing sleeve serving to preventing unwanted inner movement of said outer wall means. |
