Definitions

  • This invention relates to injection moulded containers.
  • Paint and similar materials are usually sold in metal containers of the type having a body, a cylindrical side wall and a mouth at the top defined by a radially inwardly projecting rim. This rim defines a drip channel and tightly receives a plug-fitting lid.
  • a carrying handle is mounted in yoke fashion on the side wall with opposite end parts of the handle pivotally mounted on external projections on the side wall. The external surface of the side wall is directly printed.
  • Print is carried out on a blank of sheet metal prior to forming of the side wall of the container from the sheet.
  • a pair of projections is rivetted to the side wall after printing and each projection extends to the exterior of the side wall with a formation for receiving a respective end part of the handle.
  • FR-A-2463063 discloses a plastics moulded paint container which has its cylindrical side wall provided with integrally moulded external projections for mounting of a handle.
  • This container differs from the usual paint container in having a lid which fits over the outside of the cylindrical side wall and the side wall also has external formations for snap-fitting of the lid.
  • the grommet has to have a substantial portion at the exterior of the container to effect sealing and this substantially detracts from the appearance of the printed container, the container has to be moulded with a special formation to accept the grommet, separate processes are needed to position the grommets and it is difficult to provide an effective seal, especially with a plastics container wall.
  • the present invention is concered with eliminating the additional steps required to provide the handle mounting after printing and providing a reliable connection of the handle to the container body without making the printing process more difficult to carry out.
  • the present invention is characterised in that, prior to fitting of the handle, the circumferential external surface of the side wall is smooth without any projections, said projections extend radially inwardly from the inner surface of the side wall, each projection having a recess open to the exterior of the body, each end part of the handle having a spigot which pivotally seats in the corresponding one of the recesses, and retaining means retaining each spigot in the recess.
  • French Certificat d'Utilite' No. 7411108 discloses a barrel-shaped plastics moulding, whose body is made in two halves sealed together along their edges. A separate top is secured to the body and has a narrow neck for receiving a stopper. The neck has inwardly extending projections which receive trunnions of a handle.
  • This is a complicated construction, which could not be made in one piece by injection moulding and has no relation to the type of container with which the invention is concerned. It would not be obvious to a skilled person faced with the problem solved by the present invention, to injection mould the container with inward projections in the body side wall, if this French publication was available to him. The problem is not relevant to this publication and adaption of a container of the type for holding paint.to the construction shown in this publication would render the container useless for its intended purpose, as well as making it impossible to produce by injection moulding.
  • pivotal movement is facilitated by the provision of spaced annular ribs on a spigot of the handle, which ribs define bearings journalled in the recess.
  • This ensures that the handle cannot bind and be held in a raised position, which would interfere with automatic handling of the containers, e.g. during filling.
  • One of these ribs co-operates with a shoulder at the entrance to the recess to retain the handle in the recess.
  • the arrangement is such that the spigots can automatically be pushed into the recesses to provide the pivotal interconnections, the shoulder and/or the ribs being resilient to provide for snap-engagement.
  • the spigot is pivotally movable relative to the body of the container and this could cause a problem in mechanical handling for filling of the container. There is some vibration during conveyance and the handles could move into positions where they interfere with the process. This is prevented by providing the end of each spigot and the adjacent end wall of the respective recess with resiliently interengageable parts, which define location means for resiliently holding the handle in a given position.
  • the handle may be held positively in a precise position, or resiliently prevented from passing a precise position until a small force is applied to the handle.
  • the container shown in Figure 1 is a one-piece injection moulding and has a bottom 11, a main cylindrical wall 12 and an open mouth 13 surrounded by an inwardly extending peripheral rim 14, formed as a drip channel.
  • the bottom 11 is reinforced by a pattern of integral radial and circular ribs 15, 16.
  • the cylindrical wall 12 is provided internally with integral vanes 17 adjacent the rim 14, the vanes being spaced around the wall.
  • each boss 20 is hollow, defining a recess 21 open to the exterior of the body, but closed to the interior of the body by an end wall 22.
  • a shallow depression 23 is provided in the end wall 22.
  • the mouth of the recess is constricted by an annular rim 24 whose surface is radiussed in cross-section.
  • the container includes a carrying handle 30, only part of which is illustrated in Figures 3 and 4.
  • the handle is also moulded and is of the yoke type, conventional in paint cans, in which the handle is generally of inverted U-shape and bridges the mouth of the can in the carrying position, the free end of each leg of the U being pivotally mounted on the cylindrical wall of the can.
  • FIG 3 the end part of one leg 31 of the handle 30 is shown, and this carries a spigot 32 extending axially perpendicularly to the length of the leg 31.
  • the other leg of the handle (not shown) is similarly formed, with the two spigots lying on a common axis and extending towards each other. Each spigot engages in a corresponding one of the recesses 21.
  • Each spigot 32 is provided with a pair (or more) of axially spaced peripheral ribs 33, 34, each of which is radiussed in cross-section. These ribs engage and slide on the internal peripheral wall of the respective recess 21 to facilitate pivotal movement of the spigots in the recesses.
  • Each annular rim 24 similarly slidably engages with the external surface of the respective spigot and serves to retain the spigot in the recess by cooperation with one of the peripheral ribs 33.
  • the material of the main wall and/or the handle is sufficiently resilient to allow for snap-engagement of each spigot in its recess.
  • each spigot On the free end wall of each spigot is a detent 35, which is engageable with the depression 23 in the end wall 22 of the recess. This locates the handle relative to the body in a given position and resiliently resists movement from that position. This prevents the handle from being moved by vibration during conveyance of the containers for filling and fitting of lids.
  • the vanes 17 prevent swirling of liquid in the container, during handling, and thereby prevent spillage.
  • the cylindrical wall of the container Before fitting of the handle, the cylindrical wall of the container has a smooth exterior, with no projections, which can easily be printed.
  • the handle 30 may comprise a resiliently flexible length of material having the spigots 32 formed on each end, the flexibility allowing for bending of the spigot ends relative to the adjacent parts of the handle, instead of the spigots being formed perpendicularly to the adjacent parts of the handle.
