Definitions
- This invention relates to an explosive column assembly especially adapted for use in seismic operations and more particularly to an improved explosive column assembly and plastic containers therefor.
- plastic containers which may be manufactured in an economical manner and which containers may be assembled in a facile, efficient and economical manner.
- a further object is to provide additional desirable features heretofore not available to the art such as placing the packaged explosive under compressive force during assembly where if the container is not properly filled or if the column tends to elongate, improved contact between adjacent explosive charges is insured with attendant consistency of propagation and rate.
- Still another object is to provide plastic containers which may be quickly interconnected and locked in place.
- the present invention comprises an explosive column assembly having a plurality of substantially cylindrical blown plastic containers charged with explosive, each of said containers having an interruptively beaded male coupling with locking indentations and an end closure at one end and having an interruptively grooved female coupling with looking indentations and a yieldable seal adjacent the explosive at the other end, said containers being fractionally rotated and interconnected by said male and female couplings and locked by engagement of their respective indentations, and said containers having the end closures of the male couplings exerting compressive force on the yieldable seals and adjacent explosive of the female couplings.
- a container for explosives adapted for interconnection with like containers to form an explosive column assembly, which comprises a thin-walled elongated substantially cylindrical blown plastic container having explosive disposed therein throughout the major length of the 3,1863% Patented .lune 1, E965 container and having a yieldable seal within the container adjacent the explosive, a male coupling and end closure on one end of the container, said male coupling having at least one peripheral bead interrupted by a plurality of longitudinal slots extending a substantial length of the male coupling, a female coupling on the other end of the container, said female coupling having a plurality of interrupted peripheral grooves compatible with the bead and the slots of the male coupling, and locking indentations associated with the male coupling and the female coupling whereby like containers of explosive may be interconnected by slidable and rotatable engagement of the beads and the grooves of the male and female couplings and looked upon engagement of their respective indentations to form an
- FIG. 1 is an elevational view of a container in accordance with the invention with a part thereof in section showing the yieldable seal and adjacent explosive within the container;
- FIG. 2 is a sectional view taken along line 22 of FIG 1; and FIG. 3 is a fragmentary part elevational and part sectional view showing the interconnection of the containers of FIG. 1 to form an explosive column assembly.
- a thin-wall elongated blown plastic container 1 has an explosive 2 disposed therein throughout the major length of the container.
- a yieldable seal 3 is provided within the container 1 adjacent the explosive 2.
- a slightly tapered male coupling 4 with a convex end closure 5 are formed as a unitary structure in the thin wall at one end of the container 1 and the explosive 2 extends into the bottom of the coupling.
- the male coupling 4 has a peripheral bead 6 with no pitch near the lower end thereof which is interrupted by four equally spaced longitudinal slots 7 which extend a substantial length of the male coupling thus dividing the bead 6 into four equal segments.
- Positioned midway above each segment of the bead 6 are two female locking indentations 8.
- the upper side of the 'bead 6 has its surface at a right angle to the longitudinal axis of the container with its lower side at an angle of about sixty degrees. Similarly, the surface opposite the lower side of the bead is at a right angle and the surface opposite the upper side of the bead is at an angle of about sixty degrees.
- This arrangement forming the bead grooves 11 with the right angle surfaces and absence of pitch on the bead 6 insures durable interconnection of like containers in contrast to beveled surfaces and pitch where an assembly of containers would tend to unscrew when subjected to tension loads as imparted by their own weight.
- a female coupling 9 adapted to receive the male coupling of a like container is provided at the other end of the container 1.
- the female coupling 9 has four sets of two peripheral grooves each represented by it which grooves are compatible with the bead grooves 11 and the slots 7 of the male coupling 4. Positioned midway above each set of grooves it) are two male locking indentations 12 compatible to engage with the female locking indentations of a like container a hereinafter described.
- 1a and its like parts represent a superjacent container and 1 and its like parts represent the su-bjacent container.
- the male coupling 4a of container 1a with alignment of the indentations 12 and grooves It? within the slots 7a is slidably inserted into the female coupling 9 of container 1 with the convex end closure a exerting a positive compressive force on the yieldable seal 3 and adjacent explosive 2 whereby the yieldable seal 3 is depressed.
- the slidable insertion of the male coupling 4a proceeds until the upper end wall .of the slots 7a engages the upper indentations 12 whereby it is stopped.
- the bead grooves 11a are now in register with the grooves and the containers 1 and 1a are rotated relative to each other whereupon the grooves engage each other and the male locking indentations 12 ride up out of the slots 7a and over the male coupling body 4a into locking engagement with the female locking indentations 8a with FIG. 3 illustrating the locked position.
- the thin plastic wall of the female coupling 9 is sufiiciently elastic to accommodate the tapered male coupling 4a at its upper end to give a tight water resistant fit as well as being sufficiently elastic to permit the male indentations 12 to ride up out of the slots 7a for locking engagement with the female indentations 3a.
- a considerable bending moment can occur in the thin body plastic containers of this invention particularly when several containers are interconnected in a horizontal position and then lifted for insertion in a vertical borehole.
- a plurality of longitudinal reinforcing ribs 14 is spaced circumferentially about and substantially coextensive with that portion of the body of the container lying between the male coupling 4 and the female coupling 9.
- a plurality of girth reinforcing ribs 15 is spaced along the length of the longitudinal ribs 14 to insure overall integrity of the body structure of the container 1 against deformation under various conditions of manufacture and field handling.
- the longitudinal reinforcing ribs 14 should have a width of not more than the width of the areas 16 lying therebetween and that ordinarily five of the girth reinforcing ribs 11 spaced along the length of the longitudinal ribs give very satisfactory results for the average size of most commercial cartridges.
- the. length of the slotted portion 7 of the male coupling 4 is cor related with the upper indentation 12 of the female coupling 9 to insure that in assembling a column of the containers 1, the convex end closure 5 of the male coupling exerts a positive compressive force on the yieldable seal 3 and adjacent explosive 2 of the female coupling of a like container.
- a series of thin-wall containers was formed by blowmolding high-density polyethylene having a density of 0.962 and a nominal melt index of 0.8 (I at 190 C.) These containers were molded in a split mold designed to yield the structure heretofore described and illustrated as a preferred embodiment of the invention. Approximate dimensions of the containers were 22%" overall length; 2 body diameter; sixteen reinforcing ribs 7 wide raised & around 2 diameter; male coupling 4%" long with convex end; slotted portion 1%" long, '%2" wide and deep; bead /4" long with grooves each side /2 c. to c. and deep; female indentations diameter and 7 deep; female coupling 4% long, grooved midportion of female coupling /2" c. to c. and
- the ribbed body portion 13 long had five girth ribs 7 wide equally spaced with the exception of a midportion 4" long wherein three ribs were omitted to provide a smooth area for labeling.
- the wall thickness of the body of the container, including the female coupling, was approximately 40 mils, and the wall thickness of the male coupling was approximately 55 mils. Programming was used during the blow-molding process to obtain female couplings that were uniform in thickness and strength.
- Each of these containers was charged with approximately 5 pounds of explosive composition consisting of 49.0% nitroglycerin, 1.5% nitrocotton, 36.0% sodium nitrate, 7.0% pulp, 3.0% coated cob meal,.2.0% starch, 0.5% bagasse and 1.0% chalk.
- This charge filled each container to a heightapproxirnately level with the girth rib adjacent the female coupling.
- a cupped polyethylene sealing disk approximately 25 mils thick was then placed over the explosive and snugly filled into the annular girth rib.
- the containers thus manufactured were tested and initiated under conventional field conditions as explosive column assemblies containing from two to ten containers in each assembly. The tests were satisfactory in all respects with additional advantages hereinafter set forth.
- the containers of this invention may be formed from many of the plastic materials capable of being blown but that the economy of the material will largely dictate its use.
- linear polyethylene is preferred and has been found highly satisfactory, polyolefins generally, and copolymers and alloys thereof and other materials such as ABS terpolymer, plasticized vinyl chloride, plasticized vinyl chloride-vinyl acetate copolymer and the like may be used.
- the seal may be a plastic cup sealed around its lip and the shell body with a hot melt adhesive, or a wax such as parafiin, or resins or asphaltic compounds or the like Where extreme waterproofness is desired.
- the seals should be yieldable in respect to deflection or in respect to sliding along the wall of the container or otherwise yielding so that compressive force is gently but firmly developed with close proximity assured as between adjacent container explosive charges.
- the reinforcing ribs have been described as raised, they may be obtained also by providing a constant body diameter with the areas such as 16 depressed, thusforrning ribs such as 14 and 15.
- the explosive containers of this invention are made available in sizes from about 6 to about 36 inches in length and from about 1 to about 8 inches in diameter with the number of interconnected units dependent upon the specific service desired.
- containers are easier to prime for the shooter by conventional means; a lock type, fractionally rotated positive coupling feature making assembly or disassembly a faster and simpler task; increased protection to the powder charge because the plastic is impervious to water; a plastic unit susceptible for use wherever paper containers or metallic containers formerly were preferred and in some instances necessary; improved loading in boreholes due to flexibility as the plastic assembly will yield and slide by obstructions; and a general purpose plastic unit which does not tend to disintegrate or rust internally in the presence of moisture or watercontaining explosives and does not tend to disintegrate or rust in the presence of moisture or water as externally encountered in water-containing boreholes and unsheltered storage.
