Description

Packaging The present invention relates generally to packaging and a method of manufacture of packaging, and finds particular, although not exclusive, utility in food packaging for opening single-handedly.

Most flow-wrapped food packaging is difficult to open with one hand. Only one hand may be available while the consumer is undertaking other tasks such as riding a bicycle, or driving a car. Although it is possible to hold the packaging with one hand and use one's teeth to try and rip the packaging apart, this often leads to at last some of the food being dropped.

It is desirable to have food packaging which is relatively easily openable with one hand and the user's mouth or teeth and whereby the food is not easily dropped or lost.

In a first aspect, the present invention provides a packaging comprising a planar web of material, the web having three folds, a first fold at a first end of the packaging, and a second fold at a second end of the packaging, wherein the packaging includes first and second sides, formed by the web, lying between the first and second ends, the first and second sides forming a pocket therebetween, the packaging further comprising scaling means, extending between the first and second sides and between the first and second ends, such that they adhere the first and second sides together along their opposing edges to enclose the pocket, wherein the second side is continuous and the first side is formed by first and second end ends of the web which are arranged in overlapping relationship, and wherein the first end of the web includes the third fold, to form a first tab, the first tab arranged to he adjacent the first side, and between the first side and the second end of the web, the first tab being at least partially adhered to the second end of the web, and wherein the packaging includes an opening region in the first side configured to expose the enclosed pocket, in use, when the first tab is pulled away from the first side. To open the packaging a consumer may hold the packaging with one hand and insert the first tab into their mouth to be held between their teeth. The packaging may then be pulled away from the mouth such that the opening region controllably breaks allowing the inside of the pocket to be exposed. The rest of the packaging remains intact such that the food is not lost.

The opening region may be a frangible portion comprising an area of the web having a reduced thickness. This may be formed by such as means as scoring, or ablation, such as by use of a laser. The thickness may be reduced by 5 to 95%.

The opening region may comprise at least one slit in the web, and the packaging may include a portion of material arranged to lie over the at least one slit and to seal it.

The at least one slit may be formed by cutting the web. the portion of material may at least be partially releasable from the first side.

The opening region may extend the full width of the packaging between the first and second sides. Alternatively, the opening region may only extend across a portion of the width of the packaging. The opening region may be continuous or discontinuous.

The opening region may be located on the third fold.

The packaging may further comprise a fourth fold in the second end of the web forming a second tab. The opening region may he located on the fourth fold. Alternatively, the opening region may he located adjacent either the third or fourth folds.

More than one opening region may be provided.

The third and fourth folds may be formed adjacent one another and may be located in the first side at a distance from the first end in the region of 1% to 50% of the length of the first side.

The third and fourth folds may have longitudinal lengths parallel to the first and/or second ends.

At least one of the first and second tabs may have a dimension such that it extends away from the first side by at least 5mm. In this regard the at least one of the first and second tabs may project away from the first side perpendicularly.

The first tab may he arranged to extend away from the first side with a dimension sufficient to he gripped by a consumer's fingers or teeth. In this regard, the dimension may he the length of the first tab measured from the third fold to the end of the first tab. The sealing means may be arranged such that, in use, when the first tab is pulled away from the first side, at least a portion of the first side is separated from the second side. This may be effected by employing suitable adhesion techniques in adhering the first and second sides together such that the adhesive force, and/or the structural integrity of the web, may be overcome by typical forces applied by a consumer to open the packaging.

The packaging may have an approximate cuhoid shape. The pocket may be substantially air-tight. The web may act as a moisture barrier. The web may comprise one or more of plastics, metallic films, paper. The web may be substantially flexible. The packaging may be arranged to be formed using a flow-wrapper process. Tn this regard, the web may be configured to be wound in a roll or spool before it is formed into the packaging. The packaging may be arranged to accept food within the pocket. In this regard, only food-safe materials may be used in the packaging.

The portion of material arranged to lie over the at least one slit and to seal it may comprise air-tight and moisture barrier qualities such that when sealed over the at least one slit the pocket within the packaging is air-tight.

The portion of material may at least be partially releasable from the first side. In this regard, the portion of material may he releasably adhered to the first side by the use of appropriate means such as the application of glue, or cold or hot sealing techniques.

The third and fourth folds may he fowled adjacent one another and located in the first side at a distance from the first end in the region of 1% to 50% of the length of the first side.

The sealing means may be arranged such that, in use, when at least one tab is pulled away from the first side, at least a portion of the first side is separated from the second side.

in this way, when the at least one tab is pulled away from the first side, in use, the frangible region breaks, and the portion of the first side between the at last one tab and the first end is released from the second side along its edges such that a substantially large opening is formed in the packaging at the first end so as to expose the food within.

The third and fourth folds may have longitudinal lengths parallel to the first and/or second ends.

The possible approximate cuhoid shape of the packaging may exclude the edges of the first and second sides which have been adhered together.

The two tabs may be adhered together to form a single tab.

In a second aspect, the invention provides a method of manufacturing packaging, comprising the steps of providing a planar web of material, folding the web such that it has a first fold at a first end of the packaging, and a second fold at a second end of the packaging, such that the packaging includes first and second sides lying between the first and second ends, the first and second sides forming a pocket therebetween, the method further comprising the step of sealing the first and second sides together along their edges extending between the first and second ends, to enclose the pocket, wherein the second side is continuous and the method includes the step of forming the first side by overlapping first and second web ends, the method also comprising the step of creating a third fold in the first web end, so as to form forming a first tab, the first tab lying adjacent the first side, and between the first side and the second web end, and adhering the first tab at least partially to the second web end, and forming an opening region in the first side configured to expose the enclosed pocket, in use, when the first tab is pulled away from the first side.

The method may further comprise the steps of creating a fourth fold to thus form a second tab and at least partially adhering the first and second two tabs together to form a single tab.

The above and other characteristics, features and advantages of the present invention will become apparent from the following detailed description, taken in conjunction with the accompanying drawings, which illustrate, by way of example, the principles of the invention.

Figure 1 shows a perspective view of the packaging 10 in a closed state. The packaging comprises a web of material which has been formed into an approximate cuboid shape. This shape comprises a first side 20, and a second side 30, underneath and opposing the first side, wherein the two sides have substantially equal size and shape. The web is continuous to the extent that the first and second sides are formed by introducing two folds 40, 45, one at either end of the packaging 10 to thereby form a first and second end. In this regard the term "fold" is taken to mean that the web has been turned through approximately 180 degrees. The fold may be a sharp fold or a gradual fold. Other folds may be included at either end, or example, to provide a gusset.

The first and second sides 20, 30 are sealed together along either edge 50, 60 to form a pocket within. Sealing means such as glues, hot or cold melt adhesives, welds and the like.

A third fold 70 is formed in a first web end 75 so as to form a tab 75a. This is shown in broken line format in this Figure because it is not visible being hidden by the second web end 80. The second web end 80 overlaps this tab 75a and is adhered to it, at least partially, thus forming a single tab 90. This tab may or may riot be adhered to the first side. The third fold 70 bends the web through approxitnatcly 180 degrees such that the tab 90 lies adjacent the planar surface of the first side 20 pointing towards the end of packaging comprising the fold referenced "40".

The sealed edges 50 and 60 extend along the web ends 75, 80.

A region of weakness, otherwise referenced herein as an opening region, or frangible portion is arranged in the first side and at least partially across the whole width of the first side. It may or may not extend into the sealed regions 50, 60. The opening region may he adjacent the fold 70 under the single tab 90. However, it may he directly on the fold 70, or between the fold 70 and the end referenced "45". The opening region may be a frangible portion comprising an area of the web having a reduced thickness. This may be formed by such as means as scoring, or ablation, such as by use of a laser.

Figure 2 shows a slightly different packaging 110. The only difference is that the web end 180 includes the third fold 170, rather than the web end 175, forming a tab 180a. This fold 170 is shown in broken line fonnat in this Figure because it is not visible being hidden by the web end 175. The web end 175 overlaps this tab 180a and the two are at least partially adhered together to form a single tab 190. In this example, the region of weakness is again arranged in the first side and at least partially across the whole width of the first side. Tt may or may not extend into the scaled regions 50, 60. The opening region may be adjacent the fold 170 under the single tab 190. However, it may be directly on the fold 170, or between the fold 170 and the end referenced "40".

Figure 3 shows a cross-section through the packaging of Figure 1. 'the packaging comprises a web of material which has been formed into an approximate cuboid shape containing a pocket within where food 15 has been placed. This shape comprises a first side 20, and a second side 30, underneath, and opposing the first side, wherein the two sides have substantially equal size and shape. The web is continuous to the extent that the first and second sides are formed by introducing two folds 40, 45 at either end of the packaging 10 to thereby define a first and second end. In this regard the term "fold" is taken to mean that the web has been turned through approximately 180 degrees. The fold may he a sharp fold or a gradual fold.

The two opposing, first and second, web ends 75, 80 overlap one another above the first side. A third fold 70 is then formed in the first web end 75 so as to form a tab 75a. The second web end 80 is then adhered to this tab 75a thus forming a single tab 90. This tab may or may not he adhered to the first side. The third fold 70 bends the web through approximately 180 degrees such that the tab 90 lies adjacent the planar surface of the first side 20 pointing towards the end of packaging comprising the fold referenced "40" in the Figures.

A region of weakness, otherwise referenced herein as an opening region, or frangible portion 200 is arranged in the first side and at least partially across the whole width of the first side. It may or may not extend into the sealed regions 50, 60. The opening region 200 may lie completely within the width of, the food 15 such that when the packaging 10 is opened at least a portion of the food 15 is exposed as will he explained in more detail below. The opening region is shown adjacent the fold 70 but may be directly on the fold 70.

With reference to Figure 4, it is possible that the third fold 170 is located in the second web end 180 to bend the web through an angle of approximately 180 degrees to form a tab 180a. The first web end 175 then overlies the tab 180a, and the two tabs are adhered together at least partially to form a single tab 190 lying adjacent the first side 20 and pointing towards the opposite end of packaging comprising the fold referenced "45" in the Figures. In this regard, there may be no fold in the first web end.

Angles other than 180 degrees are contemplated for the third fold. For instance, the third fold may only bend the web through an angle less than 180 degrees, such as 50 degrees. A fourth fold of approximately 130 degrees may then be formed in the second web end 80, 180 such that the two web ends 75, 80; 175, 180 overlap at least partially and are adhered together. The position of the fourth fold is indicated by reference "76" in Figure 3. In this manner, the single tab 90, 190 may project outwardly away from the first side 20, such as perpendicularly to the plane of the first side 20.

Continuing with Figure 4, an opening region 200 is arranged in the first side and at least partially across the whole width of the first side. It may or may not extend into the sealed regions 50, 60. The opening region 200 is shown arranged above, but within the length of the food 15 such that when the packaging 110 is opened at least a portion of the food 15 is exposed as will he explained in more detail below. The opening region is shown adjacent the fold 170 but may be directly on the fold 170.

The first and second sides 20, 30 are scaled together along either edge 50, 60 to form a pocket within. 'fhe seals need to extend up to the third fold 70, 170 and preferably slightly beyond it towards the end of the first web encl.

The second side is continuous to the extent that there may be no seam across its width other than the two edge seals. The first side is continuous to the extent that there may be no seam across its width other than the two edge seals and the two web ends being sealed together.

The food 15 is shown in Figure 4 located within this pocket thin the packaging 110.

Another example packaging 310 is shown in Figure 5. This has all of the same features as shown in, and described with reference to, Figure 4. However, an additional patch 350 is arranged over the opening region and adhered to the first side 20. This patch may be required where the opening region comprises an aperture in the first side which extends through the thickness of the web from one side to the other, such that without the patch the pocket would not be airtight or sealed. The patch seals this aperture within the packaging 310 to thereby releasably seal the opening region. This patch 350 may comprise another material different from the web, or may be the same material.

In Figures 2 to 4 the single tab 90, 190 is shown with the overlaps of the tabs and web ends 75a, 80; 175, 180a being equal in length, however, it is possible that the overlap is not an equal distance, as shown in Figure 5. In other words, one tab, or web end, may be longer than the other tab, or web end. T Toweyer, the two are still adhered together to form a single tab 90, 190.

In Figures 2 to 5 and 8, the single tab 90, 190 is shown with a gap between the tabs 75a, 180a and web ends 80, 175 to ease understanding of the arrangement. However, in reality the tabs and web ends would be adhered together at least partially such that they are immediately adjacent one another. Likewise, a gap is shown in Figure 5 between the patch 350 and the first side 20. Again, this is to aid understanding of the example. In reality the patch and first side would be adhered together at least partially such that they are immediately adjacent one another.

A region of the packaging referenced "210" is indicated at the fold end of the packaging referenced "45" in Figures 4 and 5, as will he explained in more detail below.

The third 70, 170 and fourth folds 76 may be sharp folds or more gradual folds.

To open the packaging 10 with the single tab 90 lying adjacent the planar surface of the first side 20 and pointing towards the end of packaging comprising the fold referenced "40" in the Figures, the single tab 90 is first lifted away from the first side 20 and rotated through at least approximately 45 degrees such that it projects away from the planar surface of the first side 20. This tab 90 is then pulled away from the first side 20.

This will lead to the opening region rupturing thus opening the packaging. This rupturing of the opening region may be caused by frangible regions created in the first side 20 breaking such that the regions of the first side either side of the opening region separate. The first side 20 may rip away from the opening region such that the food within the pocket is more fully exposed.

To open the packaging 110 where the single tab 190 lies adjacent the planar surface of the first side 20 pointing towards the end of packaging comprising the fold referenced "45" in the Figures, the single tab 190 may either be pulled in a direction substantially parallel to the planar surface of the first side 20, or lifted slightly away from the first side 20 and rotated through an angle of less than approximately 90 degrees such that it projects away from the planar surface of the first side 20, and is then pulled away from the first side 20. This will also lead to the opening region rupturing, thus opening the packaging. This rupturing of the opening region may be caused by the frangible regions breaking such that the regions of the first side either side of the opening region separate. The first side 20 may rip away from the opening region such that the food within the pocket is more fully exposed.

Tn the case of the example, discussed with reference to Figure 5, the pulling of the tab 190 away from the first side 20 will cause the patch 350 to become detached from the first side 20 to an extent that the regions of the first side either side of the opening region are able to separate. Again, the first side 20 may rip away from the opening region, for instance towards the edges 50, 60, such that the food within the pocket is more fully exposed.

Figure 6 shows a side view of the packaging 10 such that the first 40 and second folds 45 are at either end, with one sealed edge 60 visible extending therebetween across the middle of the thickness of the packaging 10. The packaging 10 comprises the first side 20, shown upwardly, and the second side 30, shown downwardly. The single tab 90 is shown extending towards the end of the packaging 10 comprising the fold 40. The fold 70 is shown in broken lines because it is underneath the tab 90 and would not be visible as such in this arrangement.

By contrast, Figure 7 shows a side view of the packaging 110 such that the first 40 and second folds 45 are at either end, with one sealed edge 60 visible extending thercbctween across the middle of the thickness of the packaging 10. The packaging 110 comprises the first side 20, shown upwardly, and the second side 30, shown downwardly.

The single tab 190 is shown extending towards the end of the packaging 10 comprising the fold 45. The fold 170 is shown in broken lines because it is underneath the tab 90 and would not he visible as such in this arrangement.

Figure 8 shows the packaging 110 having been opened and exposing the food 15 within the pocket. In this regard, the opening region 200 has ruptured such that one side of this region 200A is located at the end of the single tab 190 and the other side 200B of this region is located at the, now free end, of the first side 20 adjacent to, or at, the location of where the fold 170 was before opening. The region 210 of the packaging which previously encapsulated one end of the pocket is now exposed, lying between the region 200A and the location of where the fold 170 was before opening. For this to have occurred the first side will have ruptured all the way across the width of the packaging between the two sealed edges 50, 60. In this Figure the sealed edges 50, 60 have also 1l ruptured although it is to be understood that this may not be required in order to open the packaging and expose the food 15.

Tt is to be understood that the packaging 10 would also appear in the same manner as shown in Figure 8 if the single tab 90 is pulled away from the pocket in a direction substantially parallel to the planar surface of the first side 20 and away from the opening region 200.

Figure 9 shows a plan view of the packaging of Figure 8, whereby the food 15 is exposed. The two regions 200A, 200B are visibly separated due to the rupturing of the opening region 200. 'fhe region 210 of the packaging which previously encapsulated one end of the pocket is now exposed lying between the region 200A and region 200B. For this to have occurred the first side will have ruptured all the way across the width of the packaging between the two sealed edges 50, 60. In this Figure the sealed edges 50, 60 have also ruptured as may be observed. Regions 50A and 5013 of the sealed edge 50 which were previously sealed together are now separated. Likewise, regions 60A and 6013 of the sealed edge 60 which were previously scaled together are now separated. Again, it is to be understood that this may not be required in order to open the packaging and expose the food 15 as the packaging may rip in other directions and in other places.

The packaging (10) may be described as one may be opened one-handedly comprising a planar web having two folds (40, 45) defining ends of the packaging and sides (50, 60) scaled together, forming a pocket for food (15), the packaging also comprising a third fold (70, 170) forming a tab (75a, 180a) adhered to the opposite web end (75, 180) to form an opening tab (90, 190), the packaging including an opening region (200) in one side configured to expose the enclosed pocket, in use, when the opening tab is pulled away from the side.

With regard to the adhesion of any of the tabs and web ends described above, adhesion, or sealing means, such as glues, hot or cold melt adhesives, welds and the like may be employed.
