Description

gunpowder packaging container

[0001] The present invention relates to a container for packaging explosives, and more specifically, to a container for packaging a pre-explosive for detonating a bulk explosive.

[0002] Generally, pentolite boosters are used as the detonators for bulk explosives.

[0003] Pentolite boosters are easy to mold into a liquid state at high temperatures and a solid state at room temperature. They are generally shaped like a cylinder with two holes in the center, with a structure in which a detonator is passed through one hole and inserted into the other, allowing them to maintain a horizontal position when inserted into a blast hole.

[0004] On the other hand, emulsion-type explosives are generally packaged in film form, and when a film-type emulsion explosive is inserted into a hole, if the packaging material is damaged by hitting a protrusion inside the blast hole, the explosive may leak out, potentially causing problems with normal blasting.

[0005] The objective of the present invention is to provide a gunpowder packaging container that allows for easy leveling when inserted into a blast hole through a loop portion formed on the bottom surface and a groove portion for protecting the angle of the line formed on the side.

[0006] Another objective of the present invention is to provide a container for packaging gunpowder that can stably fix the position of the lid by securing the container part and the lid part with a locking projection after joining, and preventing rotation of the lid part after joining.

[0007] Another objective of the present invention is to provide a gunpowder packaging container that can more safely protect the wire or shock tube connected to the detonator by forming a wire protection groove in the lid portion as well as the container portion, and can stably maintain a horizontal position when inserted into a blast hole.

[0008] To achieve the above-mentioned objective of the present invention, one embodiment of a container for packaging explosives according to the present invention is characterized by comprising: a container portion having an explosive storage space for storing explosives inside and an inlet for introducing explosives into the upper portion; a lid portion coupled to the upper portion of the container portion to block the inlet; and a ring-shaped loop portion located on the lower surface of the container portion and having a hole through which a string can pass.

[0009] In the present invention, the container portion protrudes upward and includes a neck portion having an inlet formed therein, to which the lid portion is detachably coupled. The lid portion may include an upper lid surface that blocks the inlet and a side lid portion that wraps around the outer perimeter of the upper lid surface, is positioned upright, wraps around the neck portion, and is detachably coupled to the neck portion.

[0010] In the present invention, the upper surface of the lid includes an upper surface for coupling a primer having a primer coupling hole and a hole cover portion for blocking the primer coupling hole, and the hole cover portion may have a structure that opens when a predetermined force is applied in a form in which at least a part of the outer circumference is cut.

[0011] In the present invention, the hole cover portion is formed with a diameter smaller than the primer coupling hole, so that its outer surface is positioned spaced apart from the inner surface of the primer coupling hole, and a plurality of cover connecting portions connected to the inner surface of the primer coupling hole may be positioned spaced apart on the outer surface.

[0012] In the present invention, the upper surface of the lid may include an upper surface for coupling a primer having a primer coupling hole and a guide tube for coupling a primer that is provided to protrude toward the lower side of the primer coupling hole and is formed by penetrating the primer coupling hole.

[0013] In the present invention, a ring-shaped protruding rim portion protruding from the upper surface of the primer coupling is provided around the perimeter of the upper surface of the primer coupling, and the upper surface of the primer coupling may be positioned in a recessed shape from the upper surface of the lid by the ring-shaped protruding rim portion.

[0014] In the present invention, a pair of symmetrically aligned first wire insertion grooves are formed on the outer surface of the container portion along the length of the container portion, with the upper and lower portions respectively open, and a pair of second wire insertion grooves connected in a straight line to the first wire insertion grooves are formed on the side portion of the lid in a form open in the upper and lower directions.

[0015] In the present invention, the inlet and outlet of the ring-shaped loop portion may each be positioned toward a pair of first wire insertion groove portions.

[0016] In the present invention, a ring mounting groove is formed on the lower surface of the container portion in which the ring-shaped ring portion is located inside, and the depth of the ring mounting groove is formed to be greater than the height of the ring-shaped ring portion so that the ring-shaped ring portion can be positioned in a form inserted within the ring mounting groove.

[0017] In the present invention, the ring mounting groove includes a first line guide groove connecting the entrance of the ring-shaped ring portion and the first wire insertion groove portion, and a second line guide groove connecting the exit of the ring-shaped ring portion and the first wire insertion groove portion. The first line guide groove portion and the second line guide groove portion may each be formed with an inclined surface having an inner surface facing each other from the entrance and exit of the ring-shaped ring portion to the first wire insertion groove portion, with the inner surfaces being spread apart from each other.

[0018] In the present invention, the lid portion may be formed with the same diameter as the container portion.

[0019] In the present invention, the front and rear surfaces facing the first wire insertion groove from the ring mounting groove may each be formed in a recessed shape relative to the outer surface of the container.

[0020] In the present invention, a first lid coupling projection may be protruded from the outer surface of the neck portion, and a groove or a second lid coupling projection may be positioned on the inner surface of the lid side portion so as to be caught on the lower side of the first lid coupling projection when the lid portion is coupled to the neck portion.

[0021] In the present invention, the lid side portion may include an inner wall portion that can elastically open and an outer wall portion positioned on the outside of the inner wall portion and spaced apart from the inner wall portion, wherein a projection or groove for connecting the second lid is formed on the inner surface.

[0022] In the present invention, a stopper for preventing rotation is positioned so as to protrude from the outer surface of the neck portion, and a stopper insertion groove into which the stopper for preventing rotation is inserted is provided on the inner surface of the side portion of the lid portion. When the stopper for preventing rotation is inserted into the stopper insertion groove, the rotation of the lid portion is prevented, and the position of the lid portion can be fixed in a state where the second wire insertion groove is positioned to coincide with the first wire insertion groove.

[0023] The present invention has the effect of significantly increasing convenience during insertion work into a blast hole by allowing easy leveling when inserted into the blast hole through a ring portion formed on the bottom surface.

[0024] The present invention secures the container part and the lid part with a locking projection after combining them, and prevents the lid part from rotating after joining, thereby stably fixing the position of the lid part and ensuring both convenience and safety during use.

[0025] The present invention forms wire protection grooves in the container and lid portions, respectively, to prevent exposure of the wires or shock tubes connected to the detonator along their entire length, thereby protecting the wires or shock tubes connected to the detonator more safely. Additionally, it allows for stable horizontal alignment when inserted into a blast hole, which has the effect of significantly increasing convenience and stability during the insertion process.

[0051] FIG. 1 is an exploded perspective view illustrating an embodiment of a container for packaging explosives according to the present invention, FIG. 2 is a cross-sectional view illustrating the combined structure of a container part (100) and a lid part (200) in an embodiment of a container for packaging explosives according to the present invention, FIG. 3 is a plan view illustrating an embodiment of a container for packaging explosives according to the present invention, and FIG. 4 is a bottom view illustrating an embodiment of a container for packaging explosives according to the present invention.

[0052] In addition, FIG. 5 is a front view illustrating an embodiment of a container for packaging explosives according to the present invention, and FIG. 6 is a side view illustrating an embodiment of a container for packaging explosives according to the present invention, and is a front view and a side view illustrating only a portion of the lower side of the container for packaging explosives according to the present invention.

[0053] An embodiment of a container for packaging explosives according to the present invention will be described in detail below with reference to FIGS. 1 to 6.

[0054] One embodiment of a container for packaging explosives according to the present invention includes a container part (100) having an explosives storage space capable of storing explosives inside.

[0055] The container part (100) is provided with an inlet (100a) at the top for introducing gunpowder into the gunpowder storage space.

[0056] More specifically, the container part (100) includes a container body (110) having a gunpowder storage space capable of storing gunpowder inside, and a neck part (120) having a diameter smaller than that of the container body (110), positioned protrudingly, and having an inlet (100a) formed on the upper part of the container body (110) to allow gunpowder to be introduced into the gunpowder storage space, to which a lid part (200) is detachably connected.

[0057] The container body (110) is exemplified as a container having a cylindrical shape, and the neck portion (120) is positioned so as to protrude from the upper part of the container body (110) such that its center coincides with the center of the container body (110), and is positioned at the center of the upper surface of the container body (110).

[0058] One embodiment of a container for packaging explosives according to the present invention stores a pre-explosive used for detonating bulk explosives, and is exemplified by storing an emulsion-based explosive. Although not illustrated, it may further include a detonator for detonating the pre-explosive, that is, the explosive stored in the explosive storage space, and a wire or shock tube connected to the detonator.

[0059] Additionally, a lid portion (200) that blocks the input port (100a) is attached to the upper part of the container portion (100), and the lid portion (200) is attached to the upper part of the container portion (100) to block the input port (100a), thereby sealing the interior of the gunpowder storage space and preventing the gunpowder stored in the gunpowder storage space from leaking out.

[0060] The lid portion (200) is detachably coupled to the neck portion (120) and blocks the input opening (100a) formed in the neck portion (120).

[0061] The lid portion (200) includes a lid upper surface (210) that blocks the input opening (100a) and a lid side portion (220) that wraps around the outer perimeter of the lid upper surface (210), is positioned upright, wraps around the neck portion (120), and is detachably coupled to the neck portion (120).

[0062] The upper surface of the lid (210) includes an upper surface (211) for connecting a detonator that is recessed in shape and has a detonator connecting hole (211a) in the center, and a hole cover portion (212) that blocks the detonator connecting hole (211a). The hole cover portion (212) has a structure that opens when a predetermined force is applied, with at least a portion of its outer circumference cut out.

[0063] More specifically, the hole cover portion (212) is formed with a diameter smaller than that of the primer coupling hole (211a), and its outer surface is positioned spaced apart from the inner surface of the primer coupling hole (211a), and a plurality of cover connecting portions (212a) connected to the inner surface of the primer coupling hole (211a) are positioned spaced apart on the outer surface.

[0064] When the cover connecting part (212a) is pressed with a force greater than a preset amount, it breaks, separating the hole cover part (212) from the detonator connecting hole (211a) and allowing the detonator connecting hole (211a) to be opened.

[0065] The hole cover portion (212) blocks the detonator coupling hole (211a) that opens on the upper surface (210) of the lid to prevent foreign substances from entering into the container portion (100), and opens the detonator coupling hole (211a) only when the detonator is coupled.

[0066] The hole cover portion (212) not only prevents foreign substances from entering the container portion (100), but also prevents the emulsion-based explosive from leaking out of the container portion (100) after the emulsion-based explosive is filled into the container portion (100).

[0067] A ring-shaped protruding rim portion (213) protruding from the upper surface (211) for connecting the detonator is provided around the upper surface (211) for connecting the detonator, and the ring-shaped protruding rim portion (213) is exemplified as a ring-shaped protrusion protruding along the outer circumference of the upper surface (211) for connecting the detonator.

[0068] The primer can be inserted into the primer coupling hole (211a) and coupled so as to protrude on the upper surface (211) for primer coupling by the height of the ring-shaped protruding rim portion (213).

[0069] The upper surface (211) for connecting the detonator is positioned in a recessed shape on the upper surface (210) of the lid by means of a ring-shaped protruding rim (213), so that the detonator can be connected so that it protrudes upward, and convenience and stability can be ensured when connecting the detonator.

[0070] Additionally, the upper surface of the lid (210) is provided to protrude toward the lower side of the primer coupling hole (211a) and further includes a primer coupling guide tube (214) formed by penetrating the primer coupling hole (211a).

[0071] The guide tube section (214) for connecting the detonator has a length of more than 1 / 2 of the height of the lid side section (220) to stably support the position of the detonator.

[0072] As an example, the guide tube portion (214) for connecting the detonator has a length that matches the lower portion of the lid side portion (220) in a flat plane, and the lid side portion (220) has a shape that has at least the same length as the neck portion (120) and wraps around the neck portion (120) so as not to expose it to the outside.

[0073] The guide tube portion (214) for connecting the detonator is provided to protrude from the upper surface (211) for connecting the detonator to the lower side of the detonator connecting hole (211a), thereby extending the detonator connecting hole (211a) so that the detonator can be stably inserted through the detonator connecting hole (211a), and supporting the position of the inserted detonator to fix it stably.

[0074] The container part (100) and the lid part (200) are made of plastic material and can protect the gunpowder inside from external impact.

[0075] The container part (100) is formed as a cylindrical container so that when inserted into the blast hole, the inner surface and outer surface of the blast hole can be stably inserted with a constant distance between them.

[0076] On the outer surface of the container part (100), a first wire insertion groove (130) is formed in the longitudinal direction, i.e., the vertical direction, at a spaced interval in the longitudinal direction of the container part (100), and is formed in a shape in which the upper and lower ends are each open.

[0077] The first wire insertion groove (130) is provided as a pair symmetrically with respect to the center of the container (100), and is formed as a straight line with the upper side and lower side respectively open to the upper surface and lower surface of the container body.

[0078] The first wire insertion groove (130) is an insertion groove into which a wire, such as a wire or shock tube connected to a detonator, is inserted. When the container (100) is inserted into the blast hole, the wire, such as a wire or shock tube connected to a detonator, can be prevented from coming into contact with a sharp stone or the like protruding from the inner surface and being damaged, and the detonation signal can be stably transmitted to the detonator, thereby preventing a detonation malfunction accident.

[0079] Each wire or shock tube is connected to a detonator and is inserted into a wire guide groove (132a) formed in a bottom support projection (132) on the bottom surface (130) of the container part (100), that is, the lower surface (130) of the container part (100), and is inserted into a first wire insertion groove (130) on the side of the container part (100) so as not to protrude outwardly from the bottom and side of the container part (100).

[0080] Therefore, when inserting the container part (100) into the blast hole, the wire or shock tube may be prevented from coming into contact with sharp stones protruding from the inner surface of the blast hole and be damaged, and the detonation signal may be stably transmitted to the detonator, thereby preventing a detonation malfunction accident.

[0081] A ring-shaped loop portion (300) through which a string for hanging the container portion (100) passes is located on the lower surface of the container portion (100), and a loop mounting groove portion (140) in which the ring-shaped loop portion (300) is located is formed on the lower surface of the container portion (100).

[0082] The depth of the ring mounting groove (140) is formed to be greater than the height of the ring-shaped ring portion (300), so that the ring-shaped ring portion (300) is positioned in a form inserted within the ring mounting groove (140).

[0083] The lower part of the ring-shaped ring portion (300) is positioned higher than the lower surface of the container portion (100) so that it does not protrude toward the lower surface of the container portion (100), thereby preventing damage that may occur due to rock fragments, etc., when the container portion (100) is inserted into the blast hole.

[0084] The inlet and outlet of the ring-shaped ring portion (300) are positioned toward a pair of first wire insertion groove portions (130), and the ring mounting groove portion (140) formed on the lower surface of the container portion (100) includes a first line guide groove portion (141) connecting the inlet of the ring-shaped ring portion (300) and the first wire insertion groove portion (130), and a second line guide groove portion (142) connecting the outlet of the ring-shaped ring portion (300) and the first wire insertion groove portion (130).

[0085] The front and rear sides facing the first wire insertion groove (130) from the ring mounting groove (140) are each formed in a recessed shape relative to the outer surface of the container (100), that is, the opening corner of the first wire insertion groove (130), so that the line passing through the ring-shaped ring portion (300) can be smoothly and naturally guided into the first wire insertion groove (130).

[0086] The first line guide groove (141) and the second line guide groove (142) are formed with slanted surfaces that are spread apart from each other, facing from the entrance and exit of the ring-shaped loop (300) to the first wire insertion groove (130), so that the line can be guided to the entrance side of the ring-shaped loop (300) or from the exit of the ring-shaped loop (300) to the first wire insertion groove (130).

[0087] Additionally, the first line guide groove (141) and the second line guide groove (142) are formed in a shape that spreads out from the entrance and exit of the ring-shaped loop (300) to the first wire insertion groove (130), respectively, thereby forming a space in which wires such as a wire or shock tube connected to a detonator and a wire passing through the ring-shaped loop (300) can be stably mounted together when the explosive packaging container according to the present invention is stacked and positioned inside the blast hole, and a space in which the wires and the wire passing through the ring-shaped loop (300) can be stably guided toward the first wire insertion groove (130).

[0088] The entrance corner of the first wire insertion groove (130) is formed in a rounded or tapered shape so that wires such as a wire or shock tube can be smoothly inserted into the groove, and a portion of the wire passing through the ring-shaped loop (300) can be partially inserted and supported.

[0089] The depth of the first wire insertion groove (130) is formed to be larger than the diameter of the wire connected to the detonator, i.e., the wire or shock tube, and is formed to a depth into which a part of the wire passing through the ring-shaped loop (300) can be inserted.

[0090] That is, the depth of the first wire insertion groove (130) is formed to be deeper than the diameter of the wire connected to the detonator, and with the wire inserted inside, a part of the line passing through the ring-shaped loop (300) on the outside is inserted.

[0091] The gunpowder packaging container according to the present invention can be inserted stably without shaking when suspended by a string and inserted into a blast hole by having a string passing through a ring-shaped loop portion (300) partially inserted into the interior of a pair of first wire insertion groove portions (130) and supported.

[0092]

[0093] Meanwhile, the lid portion (200) is formed with the same diameter as the container portion (100), and a pair of second wire insertion grooves (230) connected in a straight line with the first wire insertion groove portion (130) are formed to penetrate in the upper and lower directions on the lid side portion (220).

[0094] A pair of second wire insertion grooves (230) are formed by penetrating in the upper and lower directions and extending along the length of the lid side portion (220), and are connected to the first wire insertion groove (130).

[0095] In the gunpowder packaging container according to the present invention, in which the lid portion (200) is coupled to the container portion (100), the first wire insertion groove portion (130) and the second wire insertion groove portion (230) are positioned to penetrate vertically along the entire length, thereby allowing wires such as wires or shock tubes to be inserted, so that the wires such as wires or shock tubes are minimized from being exposed to the outside, thus safely protecting the wires.

[0096] On the outer surface of the neck portion (120), a first lid coupling projection (150) is protruded, and on the inner surface of the lid side portion (220), a groove or a second lid coupling projection (240) is positioned to be caught on the lower side of the first lid coupling projection (150) when the lid portion (200) is coupled to the neck portion (120).

[0097] In the present invention, as an example, the second lid coupling projection (240) is positioned to protrude from the inner surface of the lid side portion (220).

[0098] The first lid coupling projection (150) is formed such that its upper surface has an inclined surface and its lower surface has a flat surface, and the second lid coupling projection (240) has inclined surfaces formed on its upper and lower surfaces, respectively.

[0099] When the neck portion (120) is inserted into the open lower portion of the lid portion (200), the lower inclined surface of the second lid coupling projection (240) is guided to the inclined upper surface of the first lid coupling projection (150), so that the lid side portion (220) naturally opens elastically and passes through the first lid coupling projection (150) and is positioned on the lower side of the first lid coupling projection (150).

[0100] When the lid portion (200) is coupled to the neck portion (120) by a press fit, the second lid coupling projection (240) passes through the first lid coupling projection (150) by elasticity and is positioned on the lower side of the first lid coupling projection (150), and the upper surface, which is the flat surface of the second lid coupling projection (240), and the lower surface, which is the flat surface of the first lid coupling projection (150), are caught on each other, so that the lid portion (200) can be maintained in a firmly coupled state so as not to be separated from the neck portion (120).

[0101] The lid side portion (220) includes a second lid coupling projection (240) or a groove formed on the inner surface to which the first lid coupling projection (150) engages, an inner wall portion (221) that can be elastically opened, and an outer wall portion (222) positioned on the outside of the inner wall portion (221) at a distance from the inner wall portion (221).

[0102] The side portion of the lid (220) must be formed with a thickness to form a pair of second wire insertion grooves (230), but in this case, the thickness is too thick, making it difficult to elastically deform the first lid coupling projection (150) to catch on the groove or the second lid coupling projection (240).

[0103] Accordingly, the lid side portion (220) is provided with a second lid coupling projection (240) on the inner side where the first lid coupling projection (150) is caught, or an inner wall portion (221) with a groove formed on the inner side, spaced apart from the outer wall portion (222), so that only the inner wall portion (221) is elastically deformed and the first lid coupling projection (150) can be caught on the groove or the second lid coupling projection (240).

[0104] And, on the outer side of the neck portion (120), a stopper (160) for preventing rotation is positioned so as to protrude from the lower side of the first lid coupling projection portion (150), and on the inner side of the lid side portion (220), that is, the inner wall portion (221), a stopper insertion groove portion (250) into which the stopper (160) for preventing rotation is inserted is provided.

[0105] When the anti-rotation stopper (160) is inserted into the stopper insertion groove (250), the rotation of the lid portion (200) is prevented, and the lid portion (200) is fixed in a position where the second wire insertion groove (230) is aligned with the first wire insertion groove (130).

[0106] The anti-rotation stopper (160) and the stopper insertion groove (250) fix the position of the lid portion (200) at a position where the second wire insertion groove (230) of the lid portion (200) aligns with the first wire insertion groove (130) of the container portion (100) while the lid portion (200) is coupled to the neck portion (120), thereby allowing wires such as wires or shock tubes, as well as a rope that hangs the container and is inserted into the blast hole, to be stably inserted into the first wire insertion groove (130) and the first wire insertion groove (130) along the entire length of the container.

[0107]

[0108] The present invention allows for easy leveling when inserted into a blast hole through a ring portion formed on the bottom surface, thereby significantly increasing convenience during the insertion operation into the blast hole.

[0109] The present invention secures the container part (100) and the lid part (200) by connecting them and fixing them with a locking projection, and prevents the lid part (200) from rotating after connection, thereby stably fixing the position of the lid part (200) and ensuring both convenience and safety during use.

[0110] The present invention forms wire protection grooves in the container part (100) and the lid part (200), respectively, thereby preventing exposure of the wires or shock tubes connected to the detonator along the entire length, thus providing safer protection, and can maintain a stable horizontal position when inserted into the blast hole, thereby greatly increasing convenience and stability during the insertion work into the blast hole.

[0111]

[0112] Although the present invention has been described in detail using preferred embodiments, the scope of the invention is not limited to specific embodiments and should be interpreted by the appended claims. Furthermore, those skilled in the art will understand that many modifications and variations are possible without departing from the scope of the invention.
