The carton can be stored in a flat condition prior to assembly, and the lid and bag assembly can also be stored in a flat condition.
1 Claims, 5 Drawing Figures PATENTEDFEB22 1912 SHEET 1 or 2 lnvenfor ordon w, Holmes @4105 A Horneys PATENTEDFEB 22 I972 SHEET 2 [1F 2 Invenror ordon W. Holmes g E AHorneys PAINT CONTAINER This invention relates to a container for liquids, more particularly paints.
Paints for industrial and household use are commonly marketed in cans of various sizes, usually cylindrical cans. The paint manufacturer receives the cans from a supplier, and the storage and shipping of the empty cans presents serious problems owing to the amount of space they take up, thus raising the cost which is passed on to the consumer.
It is an object of the present invention to provide an altemative container construction which largely overcomes these problems.
Basically, the invention provides a container which comprises first and second separately storable components adapted to be assembled together for use, each component being collapsible into a substantially flat condition so as to minimize the space it occupies during transport and storage prior to its being used.
A container according to the invention basically comprises a carton having a base with four upstanding walls defining a rectangular top opening; a rectangular lid adapted to close the top opening, the lid providing a dispensing opening, and a depending skirt positioned to extend inside said top opening; means for securing the lid to the carton to close the top opening; a closure for said dispensing opening; and a flexible bag of a material which is impermeable to the liquid to be carried, the bag having an opening at one end which is sealed around its edge to said depending skirt.
One embodiment of the invention will now be described by way of example with reference to the accompanying drawings, in which:
FIG. 1 is a general perspective view of an assembled paint container according to the invention;
FIG. 1A shows a detail of FIG. 1 with the closure removed;
FIG. 2 is an enlarged section on line 22 in FIG. 1;
FIG. 3 is an enlarged section on line 33 in FIG. 1; and
FIG. 4 is an exploded perspective view showing the elements of the container.
Referring first to FIG. '4, the elements of the container include a carton 10, a bag assembly 11 with closure 12, and a handle 13.
The carton consists of a tubular blank (shown in the flat collapsed condition) having four panels, two of which are shown at 14 and 15, defining wall portions, and four extension flaps l6, l7, 18, 19, defining a base portion. The blank may suitably be of corrugated cardboard. As illustrated in FIG. 1, the blank is erectable into a carton having a base and four upstanding walls defining at the top a rectangular opening, the opening being closed by a rectangular lid 20. Near the top edge of the panel 15 is a short rectangular. slot 21, a similar slot being provided near the top edge of the opposite panel. This slot may be provided on all four panels if desired.
The bag assembly 11 comprises a flexible bag 22 of polyethylene or like material which is impermeable to the paint to be carried. The bag has two generally rectangular panels 23 meeting at a lower edge 24, and two generally triangular panels 25 which are gussetted to permit the bag to be folded into a flat condition against the lid 20. When the bag is filled it is distended into a cubelike shape and substantially fills the carton. The lid is a rigid one-piece moulding of thermoplastic material having a ribbed upper surface as shown in FIG. 1. Adjacent to one corner of the upper surface is a rectangular dispensing opening 26, bounded by a beaded rim 27; the closure 12, which is of the same material as the lid, is formed at its edge with a channel 28 shaped to fit on to the rim 27 and to engage it resiliently whereby to fasten the closure over the dispensing opening. A hand tab 38 is integrally moulded with the closure to facilitate its removal.
The lid 20 is formed with an integral depending skirt 29 which extends inside the top opening of the carton 10, as shown inFIGS. 2 and 3, the skirt lying immediately adjacent to the inner surfaces of the four carton walls. The lid 20 is also formed with a peripheral depending flange 30 lying parallel to the skirt 29 and defining therewith a channel into which the upper edges of the carton walls fit. The bag 22 as a rectangular opening at its upper end, defined by the edges of the four panels 23, 25, and the edges of the opening are heat sealed or otherwise joined to skirt 29 to form a continuous painttight joint.
On each of two opposite side portions of the skirt 29 is an outwardly projecting ledge 31 with integral triangular gussets 32 which form a rigid projection of generally wedged shape. The projection is adapted to engage into a respective slot 21 of the carton wall, the wedge formation permitting the lid to be placed on the carton easily, to close the top opening, but preventing its removal.
The handle 13 consists of a rod which is bent to provide a crosspiece 33 extending between two U-shaped portions 34 and two side portions 35, the side portions terminating in respective axially aligned, inwardly turned portions 36, which engage retaining means 37 in the flange 30. The inwardly turned portions may be extended to engage beneath the ledges 31. This handle formation enables the container to be supported from a rung of a ladder, or the like during use.
It will be appreciated that a stock of containers prior to being filled, may be stored and shipped easily since the amount of storage and shipping space required is relatively small. The containers would normally be shipped and stored in three lots: first, the carton blanks would be stacked in flat, collapsed condition; second, the bag assemblies would be stacked in flat, collapsed condition, the bag of each assembly being folded into the well defined on the underside of the lid by the skirt 29; third, the handles would be stored separately. The erection of the containers ready for filling by the manufacturer requires a minimum of labor, it being necessary only to erect the carton, unfold the bag, place the lid onto the carton, and fix the handle in place.
What I claim as my invention is:
l. A container for liquids comprising a carton having a base with four upstanding walls defining a rectangular top opening; said carton comprising a one-piece blank which is collapsible into a flat condition; a rectangular lid adapted to close the top opening; said lid being a one-piece rigid moulding of thermoplastics material, the lid providing a dispensing opening positioned adjacent to one corner of the lid, and a depending skirt positioned to extend inside said top opening, the lid being formed with an integral depending peripheral flange lying parallel to the depending skirt and defining therewith a channel adapted to receive the ends of said upstanding walls; means for securing the lid to the carton to close the top opening; a closure for said dispensing opening; a foldable flexible bag of a material which is impermeable to the liquid to be carried, the bag having an opening at one end which is sealed around its edge to said depending skirt; a handle comprising a rod bent to form a cross portion extending between two side portions, each side portion terminating in an inwardly turned end, said ends being aligned with one another; and the container further including means for connecting said inwardly turned ends to said depending peripheral flange.
