Priority declaration

This application claims priority from U.S. provisional application filed on 2016, 12/5, and having application number 62/335,342, entitled "Housingfor explicit Device and Method of Assembly," and is incorporated herein by reference in its entirety.

Technical Field

The present invention relates generally to a housing for an explosive device for recreational purposes.

Background

Conventional fireworks rely on a blasting charge and a housing wall or shell to produce a sufficient amount of fireworks fanning effect. Traditionally, low explosive compounds are used so that the rate of decomposition is not sufficient to produce the desired fireworks blooming effect alone. Examples of such low explosives are black powder based or flash or aluminium based charges. Accordingly, the shell of the firework serves to limit the initial detonation of the explosive compound until sufficient pressure is generated within the shell to cause it to rupture, and the pressure generated then serves to dissipate the firework effect as desired.

One of the challenges is to develop a firework shell or shell that is easy to manufacture and assemble in a compact form while increasing its burst strength and burst sound without having to increase the amount of explosive compounds in the shell.

Detailed Description

The following is a more detailed description of various related concepts and embodiments related to methods and apparatus according to the present disclosure. It should be appreciated that various aspects of the subject matter introduced above and discussed in more detail below may be implemented in any of a variety of ways, as the subject matter is not limited to any particular implementation. Examples of specific implementations and applications are provided primarily for illustrative purposes.

Various embodiments of the present invention relate to explosive devices (e.g., firecrackers) and to rugged casings and enclosures that need to contain a particular material and then burst open over a particular period of time to release the contents.

Referring to the drawings, fig. 1-6 illustrate exemplary embodiments of an explosive device 30 (see fig. 5 and 6) and a method of assembling a reinforced housing or casing for an explosive device 30 according to the teachings of the present invention. Referring now to fig. 1, an explosive device housing or casing is first formed from a base layer 5, the base layer 5 being formed from a sheet (paper-based) material 10, the sheet material 10 having a fibrous reinforcement layer 12 disposed thereon. The sheet material 10 includes, but is not limited to, paper-based materials, cardboard, paperboard, cloth, plastic cloth, leather, burlap materials, vinyl, and other extensible and perforable materials. In one exemplary embodiment, the housing or shell is formed by a base layer 5, the base layer 5 having at least one layer of a paper based material. In another exemplary embodiment, the base layer 5 is formed from multiple layers of material 24 or multiple alternating layers of paper-based material and fiber reinforcement. In one exemplary embodiment, the base layer includes 8 layers of material 24, which may be alternating layers of paper-based material and fibrous reinforcement material or about 3 to about 8 layers of paper-based material or alternating layers of paper-based material and fibrous reinforcement material (see, e.g., fig. 4).

The base layer 5 is then formed into a tubular structure 20 (fig. 2 and 3), the tubular structure 20 having a tube body 21, a seam 22 and an outer sheet 10, the tubular structure 20 having a first flap member 25 formed at a first open end 20A and a second flap member 27 formed at a second open end 20B, and having a tube body disposed between the first open end and the second open end, the tube body being collinear with the longitudinal axis 20C of the tubular structure 20, and each flap member being configured to be oriented radially at approximately 90 degrees with respect to each other. The first flip member 25 has an inner surface 26A, an outer surface 26B and a distal portion 32 located away from the housing, while the second flip member 27 has an inner surface 28A, an outer surface 28B and a distal portion 34 located away from the housing.

Referring now to fig. 4, the device housing 30 includes a first seal 32 forming a base for the housing, the first seal 33 being formed by a folded first flip member 25, the folded first flip member 25 covering the first open end 20A such that an inner surface 26A of the flip member 25 contacts and adheres to the tube. In this embodiment, the outer surface 26B is exposed and the distal end portion 32 of the first flip member 25 is generally perpendicular to the longitudinal axis 20C of the tubular structure 20. In the exemplary embodiment, multiple layers 22 of first seal 32 are shown and adhered to the body of housing 30 for added strength. The second flip member 27 is shown open such that an inner container 36 is formed in the housing 30 for disposing therein (along the core member or lead member) an explosive compound or a flammable material. In a related embodiment, a non-flammable material is disposed within the container 36, wherein a user may be interested in a sturdy housing that can later burst apart to disperse the contents.

Referring to fig. 4-6, a second seal 35 is formed, the second seal 35 forming a top 38 for the housing 30, the second seal being formed by the folded second flip member 27, the folded second flip member 27 covering the second open end 20B such that the inner surface 28A and the distal end portion 34 of the second flip member contact the tubular body 21 and adhere to the tubular body 21 to form the top or top end 38 of the housing or casing. In summary, fig. 5 shows a front view of an exemplary embodiment of a tetrahedron or 3-D pyramid shaped fully assembled shell, while fig. 6 shows a perspective view of an exemplary embodiment of a tetrahedron or 3-D pyramid shaped fully assembled shell according to the teachings herein. In other embodiments, the shell or housing is formed in tubular, spherical, elliptical, square, and rectangular shapes, and is not necessarily limited to only pyramid shapes or configurations.

In a related embodiment, and referring to fig. 6 and 7, when a combustible material or explosive compound is disposed within the enclosure (in container 36-the opening), an explosive device is formed from the enclosure or housing. One of the advantages of the described housing design for use as an explosive device is that: the housing may provide enhanced burst strength when energy, gas and pressure from ignition of the combustible material attempt to escape one of the end seals formed by the folded flip member structure. To this end, in a related embodiment, a small opening 39 is formed near the top 38, or a hole 40 is formed in one end face of the housing (fig. 7) to accommodate a lead member 42 for an explosive device or a firecracker. In another related embodiment, when the body and end seal are formed from a multi-layer substrate, the burst strength and pressure are increased by igniting the combustible material.

Referring to fig. 1-7, a method of forming a rugged housing or casing adapted to receive and contain an explosive or flammable material therein is described. The method comprises the following steps: the base layer 5 is formed from a sheet of paper based material 10 and a sheet of fibrous reinforcing material 12 disposed thereon, and then a tubular body 20 having first and second open ends 20A, 20B and a tube body 21 therebetween is formed from the base layer, the tube body being co-linear with the longitudinal axis 20C of the tube. Next, material is removed from the first and second ends of the tube to form a first flip member at the first end and a second flip member at the second end of the tube, each flip member configured to be radially oriented at approximately 90 degrees relative to each other, each flip member having an inner surface, an outer surface, and a distal end distal from the tube body. Next, the first flip member is folded to cover the first open end such that the inner surface of the flip member is in contact with and adhered to the tubular body, wherein the outer surface is exposed and the distal end of the flip member is substantially perpendicular to the longitudinal axis of the tube, thereby forming the base of the housing. Finally, the second flip member is folded to cover the second open end such that the inner surface and distal end of the second flip member are in contact with and adhered to the tubular body, thereby forming a top or cover portion of the housing or case. In a related embodiment, a method of forming an explosive device from an enclosure formed by the above method further comprises the step of disposing an explosive or flammable material within the enclosure prior to folding the second flip member. The ease of the housing or shell, and the method of constructing the explosive device described herein, allows for the manufacture of the housing and resulting explosive device using mechanized and robotic mechanical devices.

In a related embodiment for manufacturing the housing, the folded flip is adhered to the housing body (of any desired shape), and for some materials this would require a small amount of glue or adhesive to be applied before folding the flip. Some materials do not require any additional glue to adequately adhere to the housing body. In another related embodiment, the method of forming an explosive device further comprises the step of disposing an explosive or flammable material in the housing by injecting the material when inserting the lead member into the housing.

In related embodiments, the explosive devices and housings disclosed herein are configured in various sizes to meet various applications in the firework industry. In addition, the housing or shell can be made small enough to replace standard firecrackers, or large enough to replace large explosive charges in aerial fireworks. Furthermore, the housing of the explosive device can be constructed from a variety of materials and several quality levels of materials. The higher the mass of the raw material used, the better the shell strength and therefore the greater the explosion sound. The casing constructed on the basis of the described design and the resulting explosive device are also a very efficient use of the paper fibre raw material input, when there is little waste of the used material compared to the traditional method of constructing small firecrackers.
