Abstract

A container assembly comprises a plastics containers with a cylindrical side wall 1 carrying an internal annular catch 6, and a circular plastics lid 2. The lid has an annular channel 7 in its edge part and an external annular rib 14 which forms an annular recess 15 with the outer edge 8 of the lid. An annular bead 12 on the lid indicates where pressure is applied during fitting of the lid so that, when the edge 8 of the lid abuts the catch 6, a bending moment is applied at A-B to the material of the lid causing the recess 15 to open and the rib 14 to engage over the catch 6. When the pressure is removed the recess 15 closes over the catch 6 to form a seal therewith. The assembly is suitable for containing fluid such as paint. <IMAGE>

Description

IMPROVEMENTS IN OR RELATING TO LIDS FOR CONTAINER ASSEMBLIES The present invention relates to container assemblies and in particular to a means by which a lid is secured to an open topped container to form such an assembly.
According to the present invention there is provided a container assembly comprising an open topped container and a lid, said open topped container having an internal, integral and annular projection adjacent its open top forming a catch, and said lid being circular and having an annular channel in its marginal edge part with an annular rib projecting outwardly from a side wall of the channel such that an external annular recess is formed by the rib and the periphery of the lid, said annular recess being engaged by the catch to form a seal therewith.
The present invention also provides a method of forming a container assembly comprising providing an open topped container having an internal, integral and annular projection adjacent its open top forming a catch, and providing a lid having an annular channel in its marginal edge part with an annular rib projecting outwardly from a side wall of the channel such that an external annular recess is formed by the rib and the periphery of the lid, and fitting the lid onto the container so that the rib is received in the open top and the catch is engaged in the recess to form a seal therewith.
The present invention also provides for one or more raised annular beads on the outer surface of the lid. The, or one of the, annular beads is preferably located adjacent to the annular channel on the side thereof nearest to the periphery of the lid so that it can be used as an indicator or location at which pressure should be applied to the lid when it is fitted to the container whereby a bending moment is applied to the material of the lid (by the reaction of the lid on the container) causing the annular recess to open and when the pressure is removed, close over the catch.
The container assembly of the present invention can be constructed from, for example, any semi-rigid plastics, and was primarily developed for use in holding fluids such as paint (although it will be appreciated that such use is not intended to be a restriction on the scope of the invention).
A container assembly constructed in accordance with the present invention will now be described, by way of example only, with reference to the accompanying illustrative drawing which shows a cross section through a portion of the wall and lid of the assembly.
The parts of the embodiment illustrated are moulded in serni-rigid plastics, (of which a preferable material is polypropylene) and is suitable for use as a paint container. The container assembly shown in the figure comprises an open topped container having a cylindrical wall 1 and a circular lid 2. The wall 1 has a rim 3 projecting perpendicularly from its inner surface 4 in close proximity to one end 5 of the wall 1. The rim 3 is generally L-shaped in cross section and includes an internal annular projection in the form of a catch 6.
The lid 2 has in its upper surface a U-shaped annular channel 7 in its marginal edge part (close to its outer edge 8). The channel 7 has side walls 9 and 10 converging to a base 11. A raised annular bead 12 extends concentric with and around the radially outer side of the channel 7.
An annular rib 14 projects from the radially outer surface of the side wall 9. The rib 14 and the edge 8 define an annular recess 15 of a size just sufficient to accomodate the catch 6.
When the lid 2 is fitted to close the open topped container, the bead 12 is used as an indicator and provides a bearing surface 13 at which pressure is applied to the lid in the direction of arrow A. As pressure is applied to the lid 2, the rib 14 enters the open top of the container and moves over the catch 6, while the outer edge 8 abuts the top or uppermost surface of the catch 6, so that the catch 6 is engaged in the recess 15. The catch 6 is retained by the natural resilience of the container within the recess 15 and forms a seal between the wall 1 and the lid 2 around the entire circumference of the lid 2.
The rim 3 is reinforced or supported on the wall 1 by a circumferentially space array of internal webs 16 so that flexure of the plastics material which is necessary to permit the engagement of the catch 6 with the recess 15 is predominately permitted by the material of the lid.
During fitting of the lid 2 by the application of pressure in the direction A on the rib 12, the underside of the edge 8 abuts the top of the catch 6 so that there is a reactive force on the lid as indicated in the direction of arrow B. As a consequence the marginal edge part of the lid is subjected to a bending moment by the forces indicated at A and B causing the mouth of the annular recess 15 to open and receive the catch 6. When the pressure at A is removed, the mouth of the annular recess 15 closes by the natural resilience of the material of the lid so that the recess firmly engages and seals with the catch 15.

Claims (10)

1. A container assembly comprising an open topped container and a lid, said open topped container having an internal, integral and annular projection adjacent its open top forming a catch, and said lid being circular and having an annular channel in its marginal edge part with an annular rib projecting outwardly from a side wall of the channel such that an external annular recess is formed by the rib and the periphery of the lid, said annular recess being engaged by the catch to form a seal therewith.
2. An assembly as claimed in claim 1 in which indicator means is provided on the outer surface of the lid and which is located adjacent to the annular channel on the side thereof nearest to the periphery of the lid to provide indication of a location at which pressure should be applied to the lid when it is fitted to the container whereby during such fitting a bending moment is applied to the material of the lid by the reaction of the lid on the container causing the annular recess to open and, when the pressure is removed, to close over the catch.
3. An assembly as claimed in claim 2 in which the indicator means comprises a raised annular bead on the outer surface of the lid.
4. An assembly as claimed in any one of the preceding claims and which is arranged so that, during fitting of the lid to the container, the rib is displaced over the catch until a lower part of the periphery of the lid abuts an upper part of the catch remote from the rib and, upon application of pressure to the outer surface of the lid on the side of the annular channel nearest to the periphery of the lid, the or a bending force is applied to the material of the lid causing the annular recess to open and receive the catch.
5. An assembly as claimed in any one of the preceding claims in which flexure necessary for the annular recess to engage the catch is predominantly permitted by flexure of the material of the lid.
6. An assembly as claimed in claim 5 in which the catch is restrained from flexure by a circumferentially spaced array of internal webs extending between the catch and a side wall of the container.
7. An assembly as claimed in any one of the preceding claims in which the container and lid are mouldings of semi-rigid plastics.
8. A container assembly substantially as herein described with reference to the accompanying illustrative drawing.
9. A method of forming a container assembly comprising providing an open topped container having an internal, integral and annular porjection adjacent its open top forming a catch, and providing a lid having an annular channel in its marginal edge part with an annular rib projecting outwardly from a side wall of the channel such that an external annular recess is formed by the rib and the periphery of the lid, and fitting the lid onto the container so that the rib is received in the open top and the catch is engaged in the recess to form a seal therewith.
10. A method of forming a container assembly substantially as herein described.
