Definitions
- the invention relates to a container for holding a liquid and a dispenser for storing the containers until needed.
- a lid adapted to engage the open top of the container and having a filter for filtering the liquid while being discharged from the container is also provided.
- the invention finds particular application in spray painting and automotive repair industries. Background of the Invention In the automotive repair industry the painting of the body panels of vehicles is a frequent operation and there is always a need for containers to hold paint while it is being mixed prior to being dispensed into paint spraying equipment. If grit enters the container while the paint is being mixed or is already present in the paint it can subsequently be poured into the spraying equipment resulting in the equipment becoming clogged which is highly undesirable. Clogging can also occur as a result of lumps in the paint. Summary of the Invention
- the invention in one form relates to a lid adapted for sealing engagement with an open end of a container suitable for holding a liquid to be stirred, wherein the lid incorporates a filter for filtering the liquid as it is being poured from the container while the lid is mounted on said open end so as to close the container and be in said sealing engagement.
- the lid and container will usually be designed for single use and so can be simply discarded with a minimum of mess after the liquid has been filtered.
- the filter is particularly suitable for filtering paint although lids of the invention may also be used for filtering a large variety of other liquids including perfumes, lacquers, varnishes and like liquids, water, mineral turpentine and organic solvents. Filters having different pore sizes may be provided in order to accommodate different liquids. The pore size will be less for solvents having a relatively low viscosity compared to more viscous liquids.
- the width of the pores will be in a range of from about 10 ⁇ m to about 2 mm.
- the pore width will range from about 10 ⁇ m to about 0.5 mm and most preferably, from about 60 ⁇ m to about 250 ⁇ m.
- the surface area of the openings of the pores will usually be the square of the width and so will normally range from about lxlO 2 ⁇ m 2 to about 4 mm 2 , more preferably from about lxl 0 2 ⁇ m 2 to about 0.25 mm 2 and most preferably from about 3.6xl0 3 ⁇ m 2 to about 6.25xl0 4 ⁇ m 2 .
- the pore size of a given filter will typically be substantially constant.
- the filter will typically be in the form of a gauze or mesh and may be formed from polypropylene, polyamide and polyester or other materials resistant to common solvents, acids, bases, reducers and catalysts as may be present in a liquid to be filtered.
- the use of a discrete filter covering an opening defined in the lid allows filters with substantially reduced pore sizes to be utilised irrespective of the thickness of that part of the lid about the filter. This allows lids having filters with relatively fine pores to be provided that may not have been readily achievable by puncturing the lid due to the necessary thickness of the material from which the lid is formed.
- the lids are particularly suitable for filtering paint.
- the removal of lumps, grit, dust and lint from paint prior to being used in a spray painting gun may not only reduce the frequency of the gun clogging but may result in an improved painting outcome.
- a lid for sealing engagement with an open end of a container for holding liquid to thereby close the container wherein the lid has a recess for receiving a base of a substantially identical further container such that the further container is held steady on the lid by the reception in the recess.
- the provision of the recess facilitates stacking of the containers and reduces the possibility of the further container tipping and potentially spilling its liquid contents while the containers are being transported.
- a lid as taught herein may be provided in combination with a container.
- a container suitable for holding a liquid to be stirred will generally have an open end with a rim able to sealingly engage a lid to thereby close the container, and wherein the rim projects radially outwardly from a shoulder of the container such that when the container is nested within a substantially identical further container the shoulder rests on the rim of the further container so that the rims of the containers are spaced apart from each other by a gap of predetermined width.
- the lids and containers may be formed from any material deemed suitable.
- a dispenser for dispensing open topped containers suitable of holding a liquid including: a hollow body dimensioned to receive a stack of the containers nested one within another, each said container having a rim formed at its open end projecting outwardly from a shoulder of the container and the containers being stacked such that the shoulder of each container rests on the rim of the container in which it is nested so that the rims of adjacent said containers are spaced apart from each other by a gap of predetermined width; and a collar with an aperture through which the containers are able to be drawn base first, the collar being arranged in the body so that the aperture extends across the interior of the body; wherein the aperture of the collar is dimensioned to permit the majority of a bottom said container of the stack to be received through the aperture with the exception of the rim of that container to thereby hold the stack within the body, and the depth of the aperture is less than the gap between the rims of adjacent said containers so that the collar is able to interpose between the rims to inhibit
- the body of the dispenser may be provided with a plurality of supports on which the collar rests so as to thereby maintain the collar in a desired position within the dispenser and inhibit it from being dislodged from the body when the bottom container of the stack is drawn through the aperture of the collar.
- the supports will generally be in the form of flaps of the body that are folded into the body's interior.
- the dispenser may also have a divider held within and extending across the interior of the body so that the interior is thereby divided into first and second compartments.
- a dispensing opening will typically be provided in a side wall of the body adjacent to the first compartment so that when a stack of substantially identical lids for the containers is placed in the first compartment a lid of the stack is able to be removed from the first compartment through the dispensing opening.
- a dispenser for dispensing open topped containers suitable for holding a liquid including: a hollow body dimensioned to receive a stack of the containers nested one within another, and having a dispensing end from which the containers are able to be removed from the body; a divider held within the body in a desired position and extending across the interior of the body so that the interior is thereby divided into first and second compartments; and a dispensing opening formed in a side wall of the body and positioned adjacent to the first compartment; wherein a stack of substantially identical lids for the containers is able to be placed in the first compartment and a lid of the stack is able to be removed from the first compartment through the dispensing opening.
- the dispenser provides a reliable and convenient means for storing and dispensing the containers.
- the collar may also inhibit more than one container from being drawn from the dispensing end of the dispenser at any one time and further, allow the container to be removed using only one hand by avoiding the necessity to hold the next container in the stack to prevent its removal from the dispenser with the container being withdrawn.
- the provision of the divider allows the lids for the containers to be carried within a single dispenser with the containers thereby lowering manufacturing costs, and facilitating handling and distribution of the lids and containers.
- a collar for placement within the interior of a body of a dispenser for holding a stack of open topped substantially identical containers nested one within another, each said container having a rim formed at its open end and which projects radially outwardly with respect to a shoulder of the container, the containers being stacked such that the shoulder of each container rests on the rim of the container in which it is nested so that the rims of adjacent said containers are spaced apart from each other by a gap of predetermined width, the collar having: an aperture through which the containers are able to be drawn base first; and a plurality of openings for receiving supports of the body of the dispenser for supporting the collar; wherein the openings are positioned such that when the corresponding said supports are received therein the aperture of the collar extends across the body and the collar is able to rest on the supports so that the collar is thereby maintained in a desired position and inhibited from being dislodged from the body when a bottom container of the stack is drawn through the aperture of the collar

- a lid 20 able to be press fitted onto the open top of a deformable container for mixing paint is shown in fig. 1.
- a filter 22 for filtering grit, dust and lumps from the paint and being in the form of a sheet of polypropylene gauze covers opening 23 defined in planar cover 24 of the lid.
- the opening 23 is located adjacent to the outer edge 26 of the container to facilitate the pouring of the paint from the container through the filter directly into the paint cannister of a conventional paint spray gun.
- the filter is gripped around its periphery by the material from which the remainder of the lid is formed so as to be fixedly held in position on the lid and such that it lies substantially parallel with respect to the open top of container when the lid is mounted thereon.
- a number of air inlet holes 28 are also provided in the cover 24 of the lid to allow the entry of air into the container as the paint is being poured through the filter.
- the lid when sealingly engaged with the open top 29 of a container 30 is illustrated in fig. 2.
- the container 30 is nested in a substantially identical further container such that shoulder 36 rests on the rim 34 of the further container and so that a gap of predetermined width indicated by X is provided between the rims 34 of the containers.
- the lid 20 has a circumferentially extending flange 32 projecting downwardly from cover 24 and which engages a rim 34 of the container that extends radially outwardly with respect to shoulder 36.
- a multistorey stack of substantially identical such lids is able to be formed wherein the lids are in alignment with each other in the stack to thereby facilitate storage and supply of the lids.
- lid 20 Rather than a lid 20 provided with a filter 22, other suitable lids can also be mounted over the open top 29 of container 30.
- One such lid 38 is shown in fig. 3. This lid also has a cover 24 and a downwardly extending flange 32 for sealing engagement with the rim 34. In this instance, however, a recess 40 for receiving the base of a container 30 is defined in the cover 24 of the lid to thereby facilitate the stacking of containers filled with paint on top of each other.
- the recess 40 has a tapered peripheral wall 42 that is inclined at an angle away from the floor 44 of the recess toward the outer edge 26 of the lid.
- the angle of inclination of the peripheral wall is substantially the same as that of outer surface 44 of the container 30 and the recess is dimensioned such that the container's base is held in frictional engagement by the wall when received therein so that the risk of a container 30 toppling when placed on the lid during transportation is minimised.
- the taper of the peripheral wall 42 of the recess is more clearly shown in fig. 4.
- the depth of the recess 40 is substantially the same as the width of the peripheral wall 42 as shown by the protrusion of the peripheral wall from below the flange.
- the protrusion of the peripheral wall 42 enables it to be received in the recess 40 of a substantially identical lid when the lids are stacked together to thereby stabilise the stack while at the same time allowing the width of the peripheral wall to be maximised for holding a container 30.
- a dispenser 46 formed from a cardboard blank for holding and dispensing containers 30 is shown in fig. 6.
- the dispenser 46 has an elongate hollow body 48 of square cross-section and is provided at each end with closure flaps 50.
- a window 52 is provided in front wall 54 to enable the number of containers remaining in the interior of the body 48 of the dispenser to be readily determined.
- a transparent film 58 covers the window.
- FIG. 7 An exploded view of the dispenser 46 is shown in fig. 7.
- the body 48 has a number of further flaps 60 that are able to be folded into the interior of the body.
- Each flap 60 is provided with a pair of tabs 62 which when the dispenser is assembled, are received within corresponding slots 64 of collar 56 as will be described further below.
- the dispenser also has a locking flap 66 provided at a dispensing end 68 of the body 48.
- a tongue 70 of the locking flap 66 is able to be inserted into slot 72 of bottom closure flap 50 to thereby secure the closure flap closed.
- the interior of the body 48 is dimensioned to receive a stack of open topped containers 30 nested within one another such that the containers are maintained in stacked form at all times.
- collar 56 The positioning of collar 56 within the body of the dispenser 46 is illustrated in fig. 8. As indicated in that figure, flaps 60 when folded into the interior 74 of the body are located immediately alongside the corresponding walls 54 of the body and such that the tabs 62 are received within the slots 64. The collar thereby rests on the flaps 60 and is maintained in a position such that it extends across the interior of the dispenser's body and is held a desired distance above bottom closure flap 50 in its closed position as shown. The distance between the underside 76 of the collar and the bottom closure flap 50 is such that a container when suspended base first through aperture 78 defined in the collar will be spaced from the inner side of the closure flap. The receipt of the tongue 70 of locking flap 66 in the slot 72 of the closure flap is also shown.
- the collar 56 is more clearly illustrated in fig. 9 and comprises a substantially planar plate 80.
- a number of projections in the form of lobes 82 of the plate are spaced around and protrude into the aperture 78 so that while the majority of a bottom container 30 of the stack is able to pass base first freely through the aperture the passage of rim 34 of the container is inhibited by the lobes so that the stack is maintained within the interior of the body 48 of the dispenser 46.
- the bottom container In order to remove the bottom container from the dispenser it is simply a matter of grasping the base of the container and tilting it to one side with a downward movement so that the rim is thereby drawn through the aperture following opening of the bottom closure flap.
- the lobes are caused to deflect slighly to facilitate the passage of the container but subsequently return to their normal resting position due to the resilient nature of the material from which the collar is formed.
- the plate 80 of the collar has a thickness which is less than that of gap width X between the rims 34 of adjacent containers in the stack so that when the bottom container is drawn through aperture 78 the lobes 82 are able to interpose under the rim of the next container to inhibit it from being withdrawn from the dispenser with the bottom container.
- FIG. 10 An alternate form of a collar 56 is illustrated in fig. 10. Rather than being provided with lobes, this collar has a cylindrical wall 84 tapered such that the diameter of the aperture narrows toward the underside 76 of the plate 80. The aperture is again dimensioned to inhibit the free passage of the rim 34 of a container 30 through the collar 56.
- the collar is also provided with a raised strip in the fom of an annular ring 86 surrounding the aperture 78 which acts to reinforce the collar and so inhibit it from flexing when a container 30 is drawn through aperture 78.
- a number of panels 88 for abutment with the interior surface of the walls 54 of the body to assist in maintaining the position of the collar in the dispenser extend downwardly from the plate. With this collar the container is caused to be deformed as it is drawn through aperture 78.
- FIG. 1 Yet another dispenser 46 is shown in fig. 1 1.
- the body 48 of the dispenser is substantially the same as that shown in fig. 6 except that it is provided with a number of slots 90 through each wall 54 of the body for receiving a tab of a divider for dividing the interior 74 of the body into first and second compartments.
- a dispensing slot 92 is also provided in the front wall 54 of the body adjacent to the floor of the first compartment provided by the divider when in position.
- the dispensing slot 88 allows lids to be removed from the interior of the body when needed.
- the width of the slot is less than the thickness of two stacked lids so that only one lid can be removed from the slot at any one time.
- a further slot 94 transversely intersecting the dispensing slot 92 is provided for receipt of the thumb and forefinger.
- An opening may also be formed in a peripheral region of the divider to allow the shafts of stirrers for mixing paint in the containers to extend through the divider into the second compartment and be received within the uppermost container of the stack.
- the opening will be of a dimension such that the stirring heads of the stirrers are unable to pass through the opening so that the stirrers are thereby held in position until required. Removing one or more of the stirrers from the dispenser is simply a matter of opening top closure flap 50 to allow access to the stirrers. Rather than the opening being formed in the divider it could also be provided between the divider and the interior surface of the walls 54 of the dispenser's body 48.
