DESCRIPTION:
BRIEF SUMMARY
The present invention relates to a device for retaining a bag mouth open, and is especially but not exclusively for application with bin bags.
When depositing material into a bag, it is inconvenient to continually hold the mouth of the bag open. This function may be fulfilled by placing the bag inside a rigid cylinder such as a bin and folding the bag over the rim, but a bin is neither portable, nor can its mouth size be varied to accommodate different sizes of bags.
A plastic belt is disclosed in U.S. Pat. No. 3,627,243 for use with paper bags and which has to have a separate clamping member which must be manually displaced to lock the belt in position and can only be used with the bag mouth located outwardly thereof and not folded thereover such that the belt may fall out of the mouth and is difficult to position apart from being less easy to use.
An object of the present invention is to provide a means to help readily and automatically retain open the mouth of bags of various mouth diameters.
According to the present invention, there is provided a device to help retain the mouth of a bag open comprising an elongate body having sufficient flexibility to bend over on itself to form an annular member with both ends of the body overlapping each other, and sufficient stiffness to be self-supporting in the condition: means holding at least one of said ends adjustably to the body whereby the diameter of the annulus can be varied by moving the one end along the body relative to the other end.
Also according to the present invention, there is provided a method of helping to retain the mouth of a bag open comprising using a device comprising an elongate body having sufficient flexibility to bend over on itself to form an annular member with both ends of the body overlapping each other, and sufficient stiffness to be self-supporting in this condition: means holding at least one of said ends adjustably to the body whereby the diameter of an annulus can be varied by moving the one end along the body relative to the other end; the mouth of the bag being circumferentially held open by said annular member.
Preferably, said holding means is a sleeve through which the end slides and is held adjacent the body, and advantageously each of the two ends is held adjustably to the body by separate sleeves, the diameter of the annulus being varied by sliding one end and its associated sleeve along the body relative to the other end and sleeve.
The annular member is preferably used with a plastic bin bag or bag or other material, which is ideally suited for collecting litter with a spike for spearing paper. Preferably, a spike discharge member is provided having a notch located over the mouth of the bag for displacing paper from the spike into the bag. Advantageously a handle is provided secured to the annular member to provide a more secure grip, and also when used with the said notched discharge member, to provide an anchor base to which said notched member is secured.
According to another aspect of the invention there is a clip which will hold the elongate body whilst fitted to the bag, to a vertical surface i.e. a wall. This clip may be adjustable on the wall in order to vary the height of the annular member from the ground.
According to another aspect of the present invention a spiked pole which may be pushed into the ground to act as a support pole for the annular member with a spring clip. The spring clip may be adjusted with reference to its position on the pole by means of the application of hand pressure to the clips surfaces and thereby adjusting the height of the annular member from the ground.
The device may be used to locate a bin bag with a bin by resting on the rim thereof.
The length of band or belt should be such that there is sufficient overlap in the circumference of the closed loop in its likely position of use i.e. relative to the circumference of bag with which it is to be used, so that the loop has a tendency to lock or stick sufficiently to prevent contraction of the loop under the compressive reactive ac
