Definitions
- This invention relates to bags, and more particularly, but not exclusively, plastic bags for the disposal of refuse, garbage and the like and which may be used for disposing of household waste, such as kitchen waste, as well as the carrying of fruit and vegetables and supermarket goods, and otherwise known as produce bags.
- the invention particularly relates to such bags having flaps formed on their open ends, which flaps, after the bag has received its contents, can be tied together to close the opening of the bag and prevent its contents from spilling out during subsequent handling.
- the flaps also provide a handle formed by the tied portions of the flaps, whereby the bag can be carried, for example from the kitchen to be deposited in a refuse bin as may be provided to households by local Government authorities, or for carrying goods to or from the checkout counter in a supermarket. Flaps also save space in the bag when tied thus saving material cost and minimising wastage.
- plastic bag which may or may not form part of the common general knowledge, is disclosed in Australian patent specification number 611639 and consists of front and rear panels joined to each other along three straight sides and open on the fourth side to form an open end.
- the open end of the panels have a series of valleys and projections formed across the bag, with the projections forming flaps or tie parts which can be tied together by hand to close the opening to the bag and as discussed above.
- the bags are provided in a roll, and the ends of the panels of two of the bags in the roll are welded together and a line of weakness is formed between the two welds, whereby the two bags can be separated from each other as they are drawn from the roll.
- the other ends (opened ends) of the bags are joined to another adjacent bag but with a further line of weakness defining the valleys and projections which will be produced to provide the flaps for both those bags when they are separated from each other.
- a cut out region is formed in each bag along one of the longitudinal edge beneath the separation line so that when an individual bag is separated from the roll and opened, four flaps (ties) are formed which can be used to tie the bag closed.
- the description and claims of the Simhaee reference call for the roll of bags, and as a consequence each bag in the roll, to have one longitudinal edge which is a single longitudinal fold and that the other longitudinal edge have four gusset folds to form three gussets.
- a bag having a welded end and an open end having a series of alternating valleys and projections formed thereon with said projections providing flaps or tie parts, wherein the bag is formed from the tubular body folded upon itself at least once along its longitudinal central region, and wherein no more than two gussets are formed along each longitudinal edge of the bag.
- the bag has four or more layers of bag material overlying each other and welded together the creation of a weakness at the bottom of the longitudinal side edges of the bag, when only two layers of bag material overlie each other, is avoided, whilst the creation of no more than two gussets along each longitudinal side edge of the bag minimises the problems with the three or more gussets referred to above.
- the present invention also envisages, a method of forming a bag having a welded end and an open end having a series of alternating valleys and projections formed thereon with said projections providing flaps or tie parts, wherein a tubular body is folded upon itself at least once along its longitudinal central region and whereby no more than two gussets are formed along each longitudinal edge of the bag.
- the present invention also envisages a roll of bags, said bags being accordance with that defined above, and wherein the welded end of one bag is joined by a line of weakness to the tops of the projections of the next bag in the roll.
- the roll is orientated in its container so that the projections of each successive bag is the end that always extends and projects from the container for the roll, and thus provide for ease of gripping and without the tendency for the end of the next bag to move back into the container when the leading bag is separated therefrom at the line of weakness between the bags.
- a further advantage of the invention, when in the form of a roll of bags, is that bags are only joined together at the tops of the projections and thus the remainder of those ends of the bags are already open and separation at a line of weakness across the entire end, of what will be the open end of the bag, is not necessary as in the case with the roll of bags disclosed in Australian patent specification no. 611639.
- Figure 1 is a perspective view of a roll of bags in accordance with the preferred embodiment of the invention.
- Figure 2 is a side view of the roll of bags of Figure 1
- Figures 3, 4, 5, 6, 7, 8, 9 and 10 are schematic transverse cross-sectional views through a tube of bag material and showing four alternative ways that the tube may be folded to form a bag or roll of bags in accordance with the present invention.
- each bag 11 having a welded end 12 and an open end 13 having a series of alternating valleys and projections formed thereon with said projections providing flaps or tie parts 14.
- the welded end of one bag is joined by a line of weakness 15 to the tops of the projections or flaps 14 of the next bag in the roll.
- the roll is orientated in its container (not shown) so that the projections or flaps 14 of each successive bag is the end that always extends and projects from the container for the roll, and thus provide for ease of gripping and without the tendency for the end of the next bag to move back into the container when the leading bag is separated therefrom at the line of weakness 15 between the bags.
- a further advantage of the invention is that bags are only joined together at the tops of the projections or flaps 14 and thus the remainder of those ends of the bags are already open and separation at a line of weakness across the entire end, of what will be the open end of the bag, is not necessary as in the case with the roll of bags disclosed in the aforementioned patent specification.
- the bags, and roll of bags, in accordance with the four preferred embodiments of the invention are formed from a flattened tube 20 of plastics material and of the type used for conventional bags .
- the tube 20 is subsequently folded in accordance with the folding sequence shown in Figures 4 and 5, that is, the outer side edge portions 20a are firstly folded inwardly across the remainder of the tube but on opposite sides thereof as shown in Figure 4, whereafter the tube is folded upon itself along its longitudinal centre line as shown by the arrow in Figure 4 to produce the folded bag or roll as shown in Figure 5.
- the necessary cutouts 13 and welds 12 are then formed, whilst, in the case of a roll of bags, the lines of weakness 15 are also formed.
- the tube 20 is folded in accordance with the folding sequence shown in Figures 6 and 7, that is, the outer side edge portions 20a are firstly folded inwardly across the remainder of the tube but on the same side thereof as shown in Figure 6, whereafter the tube is folded upon itself along its longitudinal centre line as shown by arrow A in Figure 6 to produce the folded bag or roll as shown in Figure 7.
- the folded tube 20 as shown in Figure 6 may be folded in the opposite direction as shown by arrow B in Figure 6 to produce the folded bag or roll as shown in Figure 8.
- the necessary cutouts 13 and welds 12 are then formed, whilst, in the case of a roll of bags, the lines of weakness 15 are also formed.
- the bag is folded upon itself along its longitudinal mid-region so that opposite edges 20b of the bag are placed adjacently on one side while a first fold line 20c is formed on the opposite side.
- the tube is subsequently folded again along its mid-region so that the first fold 20c line is placed adjacent to the edges 20b of the bag and thereby forming a second fold line 20d.
