Definitions

  • This invention relates to the packing for transport of articles susceptible to damage by impact. as by a blow or fall, or by mishandling.
  • the invention is thus applicable to the packing of fragile or otherwise damageable or breakable articles.
  • a particular object of the invention is to provide packing means enabling a hitherto unattained standard of safety in the transport and handling of electric detonators as used in blasting and like operations in connection with explosive materials.
  • detonators commonly consist of the detonator proper, which is a small cylindrical object containing the detonating charge, and attached thereto a. long electrical lead or cable which for convenience of handling before use is bundled in the form of a hank tied round its middle as by the free end of the lead, so as to afiord a long bundle of relatively small cross-section.
  • detonators are usually carried by shotfirers in mines and quarries and like workings in boxes which hold a number of the detonators. These have to be handled in diflicult and arduous conditions, often in poor light, and it is a disadvantage of the boxes hitherto employed that in the removal of one detonator it is possible for another to be inadvertently displaced or withdrawn, with evident dangerous possibilities. Moreover, having regard to the conditions in the workings, insufiicient protection has heretofore been provided against the possibility of detonators being damaged or exploded by the boxes being dropped or knocked against hard objects by inadvertence of or accident to a man carrying them.
  • the invention provides improved packing means for such susceptible articles, and particularly for detonators as aforesaid, comprising a container subdivided into compartments, each compartment being adapted to hold one article and having means for retainin said article against accidental displacement.
  • the invention provides retaining means of flexible or'resilient material for such susceptible articles, which means serve to retain the articles individually and jointly against accidental displacement in or from a compartmented container, and as insulation against shock for such container Within an outer casing or box.
  • the retaining means may include at least one resilient projection disposable transversely across or partly across the open end or within and adjacent t e open end of a compartment in a con- 2 tainer for substantially enclosing and/or gripping an article housed within the compartment.
  • Such means may comprise a pair ofinverted L-section members having each a vertical web adapted to be disposed against the upper part of one of two opposite walls of a container, and a transverse or horizontal web disposed to extend towards the like web of the other member across the open mouth of a compartment or the open mouths of a row of compartments.
  • the retaining means may comprise a cap or cover member for a compartment or a plurality of compartments in a container, said member havin twovertical webs adapted to be disposed against the upper parts of two opposite walls of the container and a pair of tongues or a plurality of pairs of tongue disposed to project towards one another over thefmouth of the rows or each compartment.
  • the cover member may be made of natural or synthetic rubber or other resilient material.
  • the tOngues may be moulded or otherwise formed or afiixed to project transversely by their own resilience across the open end of a compartment, so as to be deformable only by substantial force, as with the fingers, for the insertion or removal of an article into or from a compartment.
  • the cap or cover member may be provided with a slot or slots in register with said mouth or one with each of said mouths, through which slot or each of which slots the underlying compartment is individually accessible.
  • the tongues may be such as normally to extend upwards substantially in the planes of said webs, each of an op.- posed pair of tongues carrying one of two mutual- 1y engageable elements of a fastening device such as a press stud, so that the tongues may be secured together over an article inserted into a compartment and the article may thereafter be removed or displaced only when the tongues are deliberately separated upon releaseof the fastening device.
  • a fastening device such as a press stud
  • retaining means may be adapted to project inwardly, through an aperture in one wall of a compartment, or through apertures in opposite walls ofa compartment, from pads, plates, strips, bands or the like disposable outside said walls, the projection or projections being such as to grip resiliently an article inserted in the compartment.
  • said vertical webs or said lastmentioned pads, plates, stripsor the like may serve as insulation against impact shock between a container, to which such member or members is or are applied, and an outer casing or box, or between two such containers juxtaposed in a casing or box.
  • the invention further provides the combination of retaining means as aforesaid with a container, having a compartment or a plurality of compartments for or each for one susceptible article, with retaining and shock-insulating means as aforesaid.
  • the invention provides the combination of an outer casing or box, one or more of such compartmented containers, and means as aforesaid for retaining susceptible articles one within each of the compartments and for insulating the container or containers against shock within the casing or box.
  • Figure 1 is a perspective view of a detonator box and cover, partly broken away,
  • Figure 2 is a vertical section on the line 11-11 of Figure 1
  • Figure 3 is a plan of a box with cover removed and with modified retaining means
  • Figure 4 is a fragmentary vertical section corresponding to the upper part of Figure 2 and showing another embodiment
  • Figure 5 is an elevation of the retaining means shown in Figure 4, with the box and cover removed.
  • Figure 6 is a fragmentary vertical section, similar to Figure 4, of yet another embodiment.
  • Figure 7 is a plan view of the box shown in Figure 6, with its cover removed.
  • a casing for the carrying of blasting detonators comprises a box l e. g. of tinplate, rubber, alloy or other suitable material, fitted with a lid 2 which has a carrying handle 3 of suitable form and with belt loops 4 through which a mans belt may be passed to enable the carrying of the box in a manner which leaves a man's hands free.
  • Any suitable means may be provided for locking the lid to the box by co-operating part-s fixed to the box and lid respectively, and in one convenient arrangement, as illustrated, the box and the lid are provided externally with a hasp 5 and a staple 6 to enable the box to be padlocked.
  • the bottom of the box may be fitted internally with a resilient or soft pad 7, e. g. of felt, and the lid also may have resilient or soft lining 8, which again may be of felt.
  • the box there may be disposed within such outer box at least one, or as shown in Figure 1, preferably two, inner containers 9 divided into a plurality of deep compartments IQ of relatively small cross section, open at the top, each intended to hold one detonator such as H.
  • the box is provided with two inner containers 9, each of which has a single rank of compartments 10, e. g. five, the two containers being disposed side by side (although containers may be disposed end to end, or otherwise).
  • each container Over the upper part of each container as shown in Figure 1 are disposed retaining means which comprise a pair of inverted L-section members I2 having each a, relatively deep vertical web l3 adapted to be disposed against the lateral surfaces of the upper parts of the container walls,
  • Such retaining members are desirably to be made of a resilient material such as rubber, and so that the transverse webs i4 main tain their normal position by their own resilience.
  • transverse webs M of each pair extend to wards one another so that their free edges almost touch.
  • a detonator into any of the compartments of a container it is nec essary deliberately to displace or deform the overlaying pair of webs.
  • a similar deformation or displacement is also necessary. as with the hugers, in order to grip and withdraw a detonator from any of the compartments, and it will be appreciated that in the course of such withdrawal the possibility of disturbance or displacement of a detonator or detonators in any of the adjacent compartments is made practically impossible.
  • the containers are insulated from such box, the only contact with the interior of the box walls being through the vertical webs of the retainer members at the upper parts of the containers, and lower parts of the containers having a certain degree of freedom for swinging under shock applied to the box.
  • the two containers are themselves separated by the double thickness of the interposed vertical webs of the two retainer members as will be clearly seen in Figure 2, so that the possibility of their being caused to knock against one another is practically completely prevented.
  • retaining means for the detonators is in the form of pairs of strips l8 adapted to be disposed and to afiord shock insulation between the upper parts of the walls of each of the containers and the box, and between the containers themselves, as shown, each strip having a plurality of tongues l9 extending upwards, each member of an opposed pair of tongues carrying one element of a press stud 20 and each pair of tongues being disposed so that on deformation to fasten the stud the tongues are brought together over one of the compartments in a container.
  • detonators when detonators have been individually inserted in the compartments iii, they may be secured therein by fastening the associated pairs of tongues I9 over the compartments, and can then be withdrawn individually only by deliberate unfastening of the tongues.
  • the vertically extending portions I3 (Fi ures 1 and 2) or l5 ( Figure 3) or. l8 ( Figures 4 and 5) of the retaining means may be extended round the end walls 2
  • the upper part of the container may be inserted into a continuous resilientflange or band of retaining means, which may present a pair ofhorizontal opposed webs. such, as It ( Figures 1 and 2) or a transverse. portion it. with slots I! ( Figure 3) or tongues such as it withnpressstuds 20 ( Figures 4 and 5.) as may be desirable or convenient.
  • This embodiment has the further advantage that the number of detonators in the box is clearly visible, without need to touch or displace the re-' taining means.
  • the aforesaid strips or plates at of resilient material disposed one on each side of a container may be substituted by a band disposable around the upper part of the container, with bosses and. tongues as required.
  • at least one boss and tongue assembly may be attached to a separate pad.
  • a pad, plate or strip such as 24, or an equivalent band carries a plurality of bosses 25, these and the co-operating apertures 22 in the container walls may for convenience be circular, but when a pad carries a single boss, this and the co-operating aperture is desirably polygonal, e. g. rectangular, for retaining the tongue 25 in suitable transverse attitude.
  • a container fitted with such pads, plates, strips or band, when inserted in a box, as previously described, is insulated resiliently from shocks received by the box, and a plurality of containers so inserted are likewise insulated from one another.
  • the inner containers may be madev as desirable or convenient from any suitable material, e..g., metal cast, welded, riveted or beaded form, or
