Definitions

  • the subject of the invention is a cap intended to be placed at the ends of pipes and similar tubular bodies, particularly but not exclusively of cast iron pipes, in order to protect these ends during handling and during the transport of these bodies.
  • Caps or protective caps for pipes or the like, are already known, made of cardboard or of composite material with superimposed layers of cardboard and plastic.
  • document G B-A-537,287 describes a protective packaging for crowns of electric wires according to the preamble of claims 1 and 7 which comprises a central strip intended to be closed on the external cylindrical face of a crown of electric wires. From the two longitudinal edges of this central strip extend tabs with a trapezoidal profile which narrows away from the central strip. These tabs are intended to be folded down on a flat lateral face and on the inner cylindrical face of the crown. The tabs of the opposite edges overlap each other on the inner cylindrical face and, so that they remain in this position, they are provided with a layer of adhesive on their end portions.
  • the document FR-A-856 245 describes a similar package having the same use but the tongues are of rectangular profile and the central strip has transverse fold lines in the extension of the cuts between the tongues.
  • the closed central strip has successive flat faces; the tabs are folded only on the flat lateral faces of the ring of wires and they partially overlap each other. It is planned to stick a sheet of paper or cardboard on the folded tabs to make them hold in their position.
  • the caps produced according to these documents are not suitable for protecting the end portions of the pipes.
  • Document FR-A-2 208 378 also discloses a protective cap for the end of pipes having a cylindrical skirt to protect the external lateral face of the pipe, a flange turned inside to protect the edge of this pipe and lips angled inward to protect the inside of the pipe. However, these inclined lips are separated in their free end portions by cut slits.
  • the caps produced according to this design do not have a protective part covering the inner face of the pipe well; each one is suitable only for one dimension or a narrow range of dimensions of the pipes and they have a large bulk in volume.
  • the main object of the invention is to provide a protective cap or tip for the ends of tubular bodies, in particular pipes with which the inner face of the latter is effectively covered, at all times, with a protective wall.
  • the invention also has the secondary aim of achieving a cap that can be kept flat and suitable for tubular bodies very different in size, while providing in all circumstances good protection of the outer surface of the wafer and the inner surface end parts of the tubular bodies.
  • the invention also aims to achieve a cap of the type defined above with which the folded tabs remain in place without the use of adhesive.
  • a protective cap comprising a skirt terminated on a lateral edge by a folding groove, a band folded 90 ° towards the inside of said skirt and joined to this lateral edge, tabs folded back to a position parallel to said skirt with inside thereof, joined at one end to said strip, and separated from each other by cut slits which extend across said strip by dividing the latter into strip sections from the groove of folding which runs along the skirt to the free edge of these same tabs, according to the invention, these cut slots have, at least in their extreme part close to the free edge of the tabs, a generally inclined direction making an acute angle with this free edge and thus showing a point on one of the sides of each tab.
  • each point engages with the neighboring edge of the neighboring tongue.
  • the cut slots follow a curved line showing a convex edge on a tongue and a concave edge on the neighboring tongue, this concave edge being that which gives rise to a point.
  • each cut slit follows a curved line at least from said strip towards the free edge of the tongue and, for a short distance before reaching this free edge, it follows a straight line substantially perpendicular to the latter. giving rise to a heel on the convex edge and a truncated point on the concave edge.
  • the cut blank shown in Figure 1 comprises a rectangular body 1 which will become the skirt 1 '( Figure 2) of the cap after closing on itself of this body.
  • a slot 2 In an extreme part in the direction of the length of the body 1 is cut a slot 2 while the opposite extreme part is provided with a tab 3 with an end longer than the slot 2 and able to be engaged there obliquely, to remain there hung.
  • Other complementary means of attachment could be used.
  • the body 1 of the blank which will become the skirt 1 ′, has a lateral edge 4, designated by the reference 4 ′ on the cover, to which is joined a strip 5 after which there are tabs 6.
  • a first folding groove 7 is provided between the body 1 and the strip 5; a second folding groove 8 is provided between the strip 5 and the tongues 6.
  • the tongues 6 are separated from each other by a cut-out slot 9 which extends through the strip 5 to the first folding groove 7 which extends between this strip and the body 1.
  • Each of the cut slots 9 comprises, from the folding groove 7, a first part 9A which cuts the strip 4 transversely to the longitudinal direction of the latter, a second curved part 9B over almost the entire length of each tongue 6 , a third 9C which is perpendicular or substantially perpendicular to the free edge 10 of the tongues 6.
  • This configuration of the cut slots 9 shows on each tongue 6 a concave edge 11 and on the tongue 6 immediately adjacent a convex edge 12. This convex edge 12 does not reach the free edge 10 of the tongue; it is terminated by a short straight edge analogous to a heel 12A perpendicular to this free edge 10.
  • each concave edge 11 which would give rise with the free edge 10 to a point if it reached this free edge, is interrupted before the latter by a short rectilinear edge perpendicular to this same free edge 10. This gives a truncated tip 11 A.
  • a folding groove 13 extends transversely to the body 1 to the opposite free edge 14 of the latter.
  • Each of these folding grooves 13 is accompanied by a reinforcing rib, in a manner known per se.
  • two longitudinal reinforcing ribs 15 are also provided along the length of the body 1.
  • the tongues 6 ' are then substantially parallel to the skirt 1'.
  • This engagement of the tongues 6 'folded down successively is made possible as a result of the closure on itself of the skirt 1 and of the folding which takes place inwards along a shorter perimeter.
  • the concave 11, convex edges 12 between the tongues and between the folded strip sections 15 become practically contiguous.
  • the edge as well as the inner face of the pipe, which is often covered with a thin and mechanically fragile layer, are well protected by a protective wall which is very close to it and which remains permanently in its protective position. until the cap is removed from the pipe.
  • the cap of the invention can be made of cardboard and of any material having the desirable protective qualities, of plastic or of composite material.
  • the folding grooves 12, not necessary with a flexible material, allow the use of a rather rigid material which can be closed in facets 16.
  • the cap of the invention can be made of material. plastic injected with other known means to keep it closed on itself to replace the tab 3. In the example described above, this tab 3 could be introduced into the slot 2 from the outside to the inside and then be folded against the inside of the skirt for better locking.
