Abstract

A container (1) has a handle (2) with a container engagement portion at each end thereof. Each engagement portion has a tongue (4) tapering from a width greater than the width of an adjacent portion of the handle to a narrower portion (7) at the free end to provide a barb where the engagement portions extend from the handle. Each engagement portion has an elongate aperture (5) extending either side of the barb and the engagement portions are engagable in diametrically opposed slots (10) in an upper portion of the container (1). The slots (10) are of a length less than the width of the tongues at the barb such that, upon insertion of the tongues in respective slots, the barbs are compressed until the barbs have passed through the slots (10) and snap outwardly into holding engagement with the material of the container defining the slots.

Description

This invention relates to attachable handles for containers such as pots, basins, trays or the like. More particularly, but not exclusively, the invention relates to containers for aquatic plants.
Aquatic plants are seeded in a pot that has a coarse mesh which allows water to permeate freely the bedding in which the plant is seeded. These pots are immersed in water until the plant is ready for sale. At this point, the plants and pots need to be lifted from their bedding pens and relocated to an area where they are more readily available for public inspection and purchase. When members of nursery staff are relocating these plants, they often have to move large numbers of pots in a manner such that the contents of the pots remain undamaged. Thus, there is a need for a device that enables personnel quickly to attach a handle to the pots, the handle and device being capable of supporting the combined weight of the pot, plant, bedding and water.
There are currently a number of devices on the market that enable a handle to be attached to a pot or other article. For example, a protrusion mounted on the side of the pot which mates with a corresponding hole in the handle upon the application of sufficient sideways force. However, due to the large manufacturing tolerances employed in the creation of these devices, it is often difficult and sometimes impossible to force the protrusion through the handle. When dealing with aquatic plants it is a disadvantage to be having to exert a sideways force, firstly because this may squash the plant, and secondly because it is more difficult for a user than inserting an element from above.
In accordance with the present invention there is provided a container and a handle therefor, the handle having a container engagement portion at each end thereof, each engagement portion comprising a tongue tapering from a width greater than the width of an adjacent portion of the handle to a narrower portion at the free end to provide barb means where the engagement portions extend from the handle, each engagement portion including an elongate aperture extending either side of the barb means, the engagement portions being engageable in diametrically opposed slots in an upper portion of the container, the slots being of length less than the width of the tongues at the barb means, such that, when the tongues are inserted in respective slots, the barb means are compressed by flexure of the material of the engagement portion towards the aperture until the barb means have passed through the respective slots and snap outwardly into holding engagement with the material of the container defining the slots.
The direction of insertion of the engagement elements into the slots is preferably parallel to the central axis of the container. This allows the engagement portions to be inserted vertically downwards in use.
The material of the container at the ends of the slots is preferably formed with groove means adapted to be engaged by the barb means for location thereof. The groove means are preferably V-shaped grooves. The barb means may comprise a barb at each side of the tongue.
A specific embodiment of a container and a handle according to the present invention is now described, by way of example only, with reference to the accompanying drawings, in which:-

Figure 1 shows a side elevational view of a pot to which a handle; incorporating the device of the present invention, is attached;
Figure 2 shows an enlarged partly sectional and cut away view of a handle engagement portion of the pot and handle of Figure 1; and
Figure 3 shows a side elevational view of the engagement device of this invention in conjunction with a sectional view of the pot wall.

With reference to Figure 1, the device of the present invention is shown incorporated into a handle 2 which is shown engaging a pot 1 with base la (partly shown) and sidewalls 1b. The pot 1 is moulded from a suitable plastics material, as is the handle 2, although other materials may be used. A lip 8 is provided on the side wall 1b. At the points where the handle 2 enters the lip 8, the lip 8 is enlarged in a direction away from the center of the pot so as to create sufficient space for formation of a slot 10 through which the handle 2 is engaged.
Figure 2 is an elevational view of a handle engagement portion 3 of Figure 1. A tongue 4 is formed integrally with and at each end of the handle 2 and engages the pot 1 through the slot 10 in the lip 8 of the pot sidewall 1b. The tongue 4 is symmetrical about the line II-II. The tongue 4 tapers to a rounded end 7, and the thickness of the tongue 4 also tapers towards the end 7 which is approximately half the thickness of the handle 2 so as to ease location of the tongue within the slot. Tapered edges 12, 13 of the tongue 4 end in barbs 6. The tongue 4 is formed with an elongate aperture 5. It will be appreciated that the aperture 5 may be of a different shape. The aperture 5 may be located between the barbs 6 so that the wall of the tongue 4 may flex inward towards the aperture 5 when pressure is applied to the barbs 6.
The slot 10 has a pair of end walls 9. The end walls 9 each have a generally V shaped depression located in the base thereof on the edge opposite the lip 8 of the pot 1. The depressions are of a shape corresponding to the profile of the barbs 6, and figure 2 shows in detail barb engagement in the depressions. The barbs 6 are capable of engaging the respective V shaped depressions thereby securely locking the handle 2 in the pot 1 and lip 8, and preventing the unauthorised withdrawal of the tongue 4 through the slot 10. The tongue 4 has a maximum lateral width along the line joining the barbs 6. At this point, the width of the tongue is appreciatively larger than the width of the slot 10. Thus, when the rounded end 7 of the tongue 4 is passed through the slot 10, the lower portion of the barbs 6 comes into slideable frictional contact with the edge of the slot 10. Continued pressure on the handle 2 and tongue 4 causes an elastic deformation of material of the tongue on either side of the aperture 5 so that the barbs to pass through the slot 10, at which point the tongue returns to its original shape. The barbs will now be capable of engagement with the end walls 9 thereby preventing removal of the handle 2 from the pot 1.
Figure 3 is a side view showing the tongue 4 engaged in the slot 10 in the lip 8 of the pot 1. In this Figure the reduced thickness of the rounded end 7 compared with the tongue 4 which facilitates the location of the rounded end 7 within the slot 10. If the handle is to be removed from the pot 1 at any stage, it would be possible to cut the handle with a suitable tool. Once the handle has been cut, the tongue and attached handle may be drawn towards the base of the pot and removed.
Numerous modifications may be made without departing from the scope of the invention. Furthermore, the pot need not necessarily be a pot, the engagement mechanism could be located in a basin or tray or other such carrying device.
In addition to the above, it is the applicants intention to provide a display area on the handle for the non-removable display of prices or other such information.
