The invention is particularly concerned with plastics containers for holding paint, but containers according to the invention may be used for any other purpose that may be desired.

From a first aspect, the invention provides a plastics liquid container having a container body and having a carrying handle mounted thereto at two locations by way of holes extending through the body of the container, and having a lid arranged to make a 15 sealing engagement inside the mouth of the container at a location between said holes and the main part of the container body in which the contents of the container are located in use, such that when said lid is in sealing engagement with said container body no flow path 20 exists between said holes and the main part of said container body, and wherein means are provided, separate from the said sealing engagement of the lid and container body, for securing the lid in the mouth of the container in its closed condition, said securing means 25 comprising interengaging means provided on the mouth of said container and said lid respectively and being arranged above said sealing engagement.

Preferably the handle is provided with mounting lugs which extend into the said holes from the outside. 30 The seal between the lid and the container body should be located inwardly of, i.e. below, the said holes for mounting the handle, so as to ensure that no leakage of the container contents can occur through the said holes when the lid is in place, and also that there can be no 35 inward leakage of air to the contents. However, means for securing the lid in its closed condition, separate from the lid seal, may conveniently be located outwardly •$*- - ;23 3 0 ;2 ;of, i.e. above, the said holes. ;If an air-tight seal is required, for example when the container is for solvent-borne paints, the lid seal ;5 polymeric material on either the lid or the container body in the sealing zone therebetween, which gasket is different in material or composition from the said lid or body and is, in its working condition, softer than the material of the latter; further details of this 10 sealing concept may be obtained from our British Patent Application No. 8820393.0. ;Preferably the container has an open top which is defined by a separately formed shroud secured around the top of the container body, the container body and the 15 shroud together providing wall regions of double thickness at least at the said handle mounting locations, and the handle being connected to the container by way of holes extending through said double thickness wall regions. ;20 Preferably the lid makes securing engagement with the said shroud and, inwardly thereof, sealing engagement with the container body. ;An embodiment of the invention will now be described by way of example and with reference to the 25 accompanying drawings, in which:- ;Figure 1 is a side elevation view of a plastics container according to the invention, particularly for containing paint; ;line III-III of Figure 2, including an enlarged view. ;Referring to the drawings, the container basically comprises a generally square-section open-topped body 1 provided with a reinforcing shroud 2 around its top, a 35 pivotally mounted handle 3, and a lid 4. Figure 1 shows the handle 3 in full lines in its stowed position, and in ghost lines in a partially raised position. Referring may be provided by means of a flowed-in gasket of ;30 ;Figure 2 is a top plan view of the container; and Figure 3 is a vertical cross-sectional view on the f'i v. w .. ;// ;c ;23 3 0 0 4 ;3 ;now particularly to Figure 3, the body 1 of the container has a radially inset portion 6 around its top, arranged to provide an inwardly facing sealing surface 7 for the lid 4 and terminating in an upwardly directed annular wall portion 8 which provides a mounting for the shroud 2. ;The shroud is received in the annular space provided by the inset portion 6 of the container body, and includes a central vertical wall portion 9 which engages face to face with the wall 8 of the body to form a double thickness wall and is formed with an inwardly facing annular hook portion 10 which engages under the bottom edge of the body wall 8 to securely attach the shroud to the body. The shroud further includes a lower annular wall portion 11 which fits flush with the top of the side wall 12 of the body 1 to define a substantially ;V..~" ;23 ;continuous outer surface therewith, and an upper annular wall portion 13 of inverted V-shape which terminates in an inwardly directed lid securing flange 14. ;The handle is formed with an integral, inwardly 5 facing, mounting lug 15 at each end thereof, which mounting lugs are rotatably received in holes 16 extending through the double thickness wall defined by the wall portions 8 and 9 of the body and shroud respectively, barbs 15a being provided on the inner ends 10 of the lugs to prevent disengagement. Thus, the handle is mounted to a double thickness wall defined in combination by the container body 1 and the shroud 2. ;The lid 4 of the container comprises a substantially flat top 17 formed with a depending 15 annular side wall 18. An outwardly and upwardly projecting annular flange 19 of the lid is formed with an annular recess 20, which snaps over the lid securing flange 14 of the shroud to secure the lid in its closed position. The lid seal is provided by way of a flowed-in 20 gasket 21 provided all around the outside surface of the lower region of the lid side wall 18. An outwardly extending annular shoulder 22 is formed on the wall 18 to define the upward termination of the flowed- in gasket 21, the effect of which is that at its top 25 adjacent the shoulder 22, and as clearly shown in the enlarged view, the outwardly facing sealing surface of the gasket is of arcuate shape so as make a particularly efficient seal with a similarly shaped inwardly facing sealing surface of the shroud wall 9. To secure the lid 30 in its closed position it is simply pushed into the mouth of the container until the lid holding flange 14 on the shroud springs into the recess 20 in the lid, while at the same time the sealing gasket 21 fits into the annular sealing surface defined by the shroud. 35 It will be noted that the seal between the lid and the container body is located inwardly of, i.e. below, the holes 17 provided in the body to mount the handle, ;233004 ;5 ;thus ensuring that the contents of the container cannot leak out through the holes and that air cannot gain access to the contents by the same route. ;A brush wiping bar 23 extends across the open mouth 5 of the container body, being spot welded at its opposite ends to a shoulder 24 on the inset portion of the body, below the lid seal. ;Where in the aforegoing reference has been made to integers or components having known equivalents then such equivalents are herein incorporated as if individually set ;Although this invention has been described by way of example with reference to possible embodiments thereof it is to be appreciated that improvements and/or modifications may be made thereto without departing from the scope of the invention as defined in the appended claims. ;forth ;T A * 23 3 0
