Definitions

  • the present invention relates to packaging or protecting members adapted to be applied to articles to facilitate transport or storage of the articles in a protected state.
  • packaging also covers generally protection and cushioning.
  • a commonly known form of packaging comprises moulded polystyrene blocks which are shaped and dimensioned for compatability with the article to be packaged.
  • the blocks can have shaped surfaces so that a set of the blocks can fit around the article whereby, when the article and block set are installed in a container e.g. cardboard box, the article is firmly located in the container.
  • a container e.g. cardboard box
  • US-A-4407898 shows a corner pad for a cubic article such as a speaker box, said pad comprising linked generally rectangular hollow elements which are foldable to set the elements at right-angles to each other whereby the member can be applied at the corner of a cubic article.
  • this hollow member does not provide a substantially improved cushioning action in comparison with the known polystyrene block packaging. It is the principal object of this present invention to provide packaging members giving improved cushioning for articles being packaged.
  • a packaging or article protecting member comprises a hollow element formed by blow moulding, the element including means giving increased cushioning performance.
  • These cushioning means preferably comprise recesses, grooves or protrusions in the element. More especially the recess, groove etc. of the cushioning means can be arranged for design deformation or collapse on loading of the element.
  • pressure regulation is achievable in the element together with controlled damping for the provision of an improved cushioning action.
  • a specific and separate pressure regulating device could be carried by the hollow element.
  • the hollow space of the element may be at atmospheric pressure but it would be possible to utilise a pressure above atmospheric.
  • the element may include means to enable inflation and deflation of the element.
  • the hollow element includes reinforcing means either as an integral part of the element or as fitted subsequently to the element. Reinforcing seams or profiling may be present, for example in the form of corrugations or by providing additional strengthening members.
  • the packaging member includes locating means for the location of an article to be protected by the packaging, the arrangement being such that the locating means is independently movable relative to portions of the element adjacent said means whereby the article being packaged (or protected or cushioned) can move relative to the hollow element.
  • the element includes edge relief, or where the element has portions defining an internal corner, relief can be provided at said corner.
  • a further preferred feature relates to the provision of a special facility enabling controlled or simplified puncturing of the element.
  • Packaging elements in accordance with the present invention when discarded and especially in the deflated state e.g. after puncturing can occupy a minimum of space vis-a-vis polystyrene block packaging, and this represents a substantial environmental benefit.
  • the present packaging member conveniently can be made from a material facilitating recycling - again an environmental advantage.
  • the packaging of the present invention can be used to package and protect a wide variety of different types of articles. These articles may comprise components of a standard shape, for example items produced in an extensive production run, or again the article may be a special customised component.
  • the packaging members may be applied at only parts of the article, for example as corner or edge pads, in particular where the article/packaging combination is to be ⁇ ibused in a container/box; or again the packaging may substantially encapsulate the article in which case an additional outer container/box may not be necessary.
  • Suitable materials for the packaging member of the invention can include polypropylene (standard) or high density polypropylene, polyethylene, PET, or rubber; or it may be appropriate to provide an individual material of special composition.
  • the material can comprise a co-injected material, that is a material comprising recycled materials. By using these co-injected materials the blow moulding can be made to provide a wall having a core of recycled material (or aerated base material) sandwiched between outer skin of higher quality material.
  • the material may include internal reinforcement.
  • Figs. 1 - 15A show generally how the present invention can be applied in packaging, whereas Figs. 16 - 24 show packaging utilising the present invention and adapted for protecting specific articles.
  • Figs. 25 and 26 respectively illustrate the use of varying wall thicknesses and of inter-engaging formations in embodiments of the invention.
  • Fig. 1 shows pictorially a portion of a packaging member 1 formed as a blow moulding, a cylindrical intrusion 2 defining a recess (blind) being provided to give improved cushioning performance, the cylinder 2 being at right angles to the top surface 1A of the member 1.
  • Fig. 1 shows the static condition whereas in Fig.
  • a downward load L has been applied (as can happen when a jarring force is imparted on the article/package combination) .
  • the load L increases the internal pressure in the member 1 but the intrusion 2 deforms (as shown dashed) and by arranging for this deformation to be in a controlled manner the effect ⁇ f the pressure variation can be regulated, and controlled damping also applied.
  • Figs. 2 - 2B show a similar arrangement but in this case the intrusion 2 is of cuboid (parallelopiped) form.
  • a slot 3 is provided for pressure regulation but the principle is again the same via controlled deformation (buckling) of the slot (Fig. 3A) .
  • the packaging member 1 in Figs. 4 to 4C utilises an external feature, i.e. a cylindrical protrusion 4 which "barrels" (Fig. 4A) when the load L is applied.
  • the member 1 of Figs. 5A is similar but in this case the protrusion is of cuboid or parallelopiped form.
  • a groove 5 is provided extending around at least some of the peripheral faces (Fl, F2, F3) of the member 1 which, when the load L is applied, moves from the normal state (Fig. 6A) to the collapsed state (Figs. 6B/6C) for controlled deformation and pressure regulation.
  • the packaging member 1 can be fitted with strapping 6 (Fig. 7) to strengthen the member, or alternatively additional strengthening could be formed integrally with the member, for example by the ribbing 7 shown in Fig. 8.
  • a further option would be to strengthen by the provision of corrugations 8 as shown in Fig. 9 to provide a reinforced seam.
  • corrugations may be added as shown for example in Fig. 9B to prevent buckling of the component as a whole or of a part thereof, when a load L is applied as shown.
  • a recess 9 for example cylindrical
  • an annular groove 10 surrounds the recess 9.
  • Fig. 10 shows the static state
  • Fig. 10A shows the situation where the article A has been displaced downwardly: it can be seen that the major effect is that the recess 9 is displaced whereas the bulk of the remainder of the member 2 including the faces remain undefor ed.
  • the member 1 comprises portions set at an angle to each other, e.g.
  • a relief groove 11 is formed at the corner of the portions as shown in Figs 11 to 11B.
  • Figs 11 and HA show the undisturbed situation, Fig. 11A illustrating an article A abutting against the internal faces Ij . , I 2 of the member 1.
  • the edge relief 11 enables an appropriate one only, e.g. Face !___ , of the internal faces to displace, and also encourage pressure and deformation regulation.
  • the outer wall I 0 of the member 1 may be corrugated per Fig. 9B to resist buckling when a vertical load L is applied.
  • corner relief 12 is provided additionally.
  • Figs. 13 and 13A show an arrangement for controlled puncturing of the member 1 which is desirable when the member 1 is to be discarded as it is then beneficial that the member can be deflated to occupy minimal space.
  • the member 1 includes a designated puncturing zone P guarded by a wall formation 13.
  • a suitable puncturing tool is at hand and to this end the tool 14 e.g. pin form can be moulded integrally with the member 1 and be movable into the wall formation 13 for puncturing at zone P. It is advantageous for the zone P to be of thinner material for ease of puncturing.
  • a further possibility is to have some form of closable air inlet or valve to enable the member to be inflated and deflated - this especially will convenience storage and transport of the member 1 when not in use.
  • Figs. 14/14A show a further arrangement for pressure control and regulation.
  • the member 1 has an annular recess 15 extending inwardly from a large diameter mouth portion 16 on a side face F s of the member, and an additional resilient device D is provided for deformation (and pressure) control.
  • this device D includes a spring 17 located between the central cylinder A of the recess 15 and a disc 18 secured in the mouth portion 16.
  • a load L applied as shown will deform the recess 15 (as indicated by dashed lines) but additionally the spring 17 will be compressed due to the barrelling of the cylinder 15A.
  • Figs. 14A show a further arrangement for pressure control and regulation.
  • the member 1 has an annular recess 15 extending inwardly from a large diameter mouth portion 16 on a side face F s of the member, and an additional resilient device D is provided for deformation (and pressure) control.
