- the side walls and top and bottom walls are formed as a tube which is closed each end by transverse seals which run the full width of the side walls to form an enclosure.
- the edges of the side walls where they join the top and bottom walls along fold lines are sealed to the adjoining edges of the top and bottom walls to form upstanding peripheral walls or rims which increase rigidity of the package.
- An object of the invention is to provide an improved package incorporating an easy open feature.
- the invention comprises a package having a flexible top wall joined at its periphery to flexible side walls to form an enclosure, the top wall being formed with a line of weakness which is adapted to be torn to create an opening in the top wall, the tear being confined between the peripheral join of the top wall with the side walls.
- the invention is applied to a package of the known type described above comprising side walls with transverse seals, and top and bottom walls folded inwards as gussets.
- a line of weakness Prior to assembly of the package, that portion which forms the top wall is formed with a line of weakness which extends across the top wall and allows it to be opened by inward pressure on the top wall to create a tear along the line of weakness.
- the line of weakness extends substantially centrally along the fold line of the gusseted top wall between the two transverse seals that permanently close the package, and the package is easily gripped in both hands, one either side of the line of weakness, with a thumb on each side to press downwards and create a tear along the line of weakness.
- the upper edges of the side walls are sealed to the adjoining edges of the top wall to form a peripheral upstanding rim which, as well as adding rigidity to the package in the known manner, further facilitates gripping of the top portions of the package either side of the line of weakness.
- a package allows the two portions of the top wall either side of the tear along the line of weakness to be folded inwards and downwards against the surrounding side walls of the package so as to leave an unobstructed opening of maximum size corresponding to the outline defined by the upstanding peripheral rim, and the torn portions of the top wall serve to line and reinforce the side walls below the upstanding rim.
- the folded sealed edges which form the upstanding rim serve to hold the torn portions of the top wall against the side walls. Therefore, in its open state, the package forms a container similar to a cup with an open top to allow maximum access to its contents and which is convenient to handle while the product is consumed.
- the packaging can then be disposed of in a tidy manner without having previously generated any additional potential litter in the form of tear strips or other torn packaging created during the opening process.

Description
- This application claims the benefit and is a continuation of U.S. patent application Ser. No. 11/721,048, filed Aug. 7, 2009, which is a 371 of international application PCT/GB2005/004790, filed Dec. 12, 2005, which claims priority to GB 0427140.9, filed Dec. 10, 2004.
- 1. Field of the Invention
- This invention relates to packaging and packages, especially flexible packages, which are easily operable to allow the consumption of products contained therein.
- A known type of flexible package is described in WO200058174 in the form of a stand up bag comprising two side walls joined by top and bottom walls formed with gussets so that they each fold inwards of the package when in the flattened form. In manufacture, the side walls and top and bottom walls are formed as a tube which is closed each end by transverse seals which run the full width of the side walls to form an enclosure. Furthermore, the edges of the side walls where they join the top and bottom walls along fold lines are sealed to the adjoining edges of the top and bottom walls to form upstanding peripheral walls or rims which increase rigidity of the package. When a pack of this type is filled with a product it maintains a rectangular shape that will stand unsupported and presents good side walls for the presentation of information relating to its contents.
- An object of the invention is to provide an improved package incorporating an easy open feature.
- According to one aspect, the invention comprises a package having a flexible top wall joined at its periphery to flexible side walls to form an enclosure, the top wall being formed with a line of weakness which is adapted to be torn to create an opening in the top wall, the tear being confined between the peripheral join of the top wall with the side walls.
- In a preferred embodiment, the invention is applied to a package of the known type described above comprising side walls with transverse seals, and top and bottom walls folded inwards as gussets. Prior to assembly of the package, that portion which forms the top wall is formed with a line of weakness which extends across the top wall and allows it to be opened by inward pressure on the top wall to create a tear along the line of weakness. Preferably, the line of weakness extends substantially centrally along the fold line of the gusseted top wall between the two transverse seals that permanently close the package, and the package is easily gripped in both hands, one either side of the line of weakness, with a thumb on each side to press downwards and create a tear along the line of weakness. Preferably, the upper edges of the side walls are sealed to the adjoining edges of the top wall to form a peripheral upstanding rim which, as well as adding rigidity to the package in the known manner, further facilitates gripping of the top portions of the package either side of the line of weakness.
- Once opened, a package according to this embodiment of the invention, allows the two portions of the top wall either side of the tear along the line of weakness to be folded inwards and downwards against the surrounding side walls of the package so as to leave an unobstructed opening of maximum size corresponding to the outline defined by the upstanding peripheral rim, and the torn portions of the top wall serve to line and reinforce the side walls below the upstanding rim. The folded sealed edges which form the upstanding rim serve to hold the torn portions of the top wall against the side walls. Therefore, in its open state, the package forms a container similar to a cup with an open top to allow maximum access to its contents and which is convenient to handle while the product is consumed. The packaging can then be disposed of in a tidy manner without having previously generated any additional potential litter in the form of tear strips or other torn packaging created during the opening process.
- Other aspects of the invention are defined in the accompanying claims.
- The invention will now be described by way of example with reference to the accompanying drawings in which:
-
FIG. 1 illustrates a package according to an embodiment of the invention; -
FIG. 2 shows the package ofFIG. 1 in a partially open state; -
FIG. 3 shows the package ofFIG. 1 in the fully open state; -
FIG. 4 illustrates a package according to an embodiment of the invention; and -
FIG. 5 shows a cross sectional view of the package ofFIG. 1 taken along line 5-5 ofFIG. 1 . - In general terms,
FIG. 1 illustrates a stand up bag of the known type composed of flexible plastics film which is formed into a tubular shape in a continuous flow process, with gusseted side walls that fold inwards. A bag or package is formed by severing a length of the tubular film front a continuous length and closing the cut ends by seals extending laterally of the length of the tube. As shown inFIG. 1 , the seals are shown as sealedflaps seals FIG. 1 . - Another known feature of this type of stand up bag is to heat seal peripheral portions of the top and bottom walls to the adjoining portions of the
upright side walls rim 6 which gives a better definition to the shape of the package. - The easy open feature according to the invention consists in providing a line of
weakness 7 in the top wall 3 of the package, and as shown inFIG. 1 , this extends substantially along the centre fold which forms the gusset in the wall production. The line of weakness is preferably formed as a continuous formation in the side wall 3 and therefore extends fully between the twoseals - The opening process of the package simply involves a consumer gripping the top of the pack either side of the line of
weakness 7 and either pulling either side of the top wall 3 apart to create a tear along the line ofweakness 7, or pressing downwards with thumbs either side of the line ofweakness 7 so as to create the tear along the line of weakness, as shown inFIG. 2 . The two portions of the top wall either side of the tear can be further pushed inwards against the adjacentupright side walls upstanding rim 6 around the top of the package, as shown inFIG. 3 . The fact that the line ofweakness 7 extends across the full width of the top wall 3 ensures that the opening created by the tear also extends the full width of the top wall to allow the maximum opening. With the two torn portions of the top wall 3 folded against the adjacentupright walls rim 6 which provides increased reinforcement or stiffness to make the open package more like a cup for convenience of use by the consumer when consuming the contents. The upstanding rim serves to help hold the two torn portions of the top wall 3 against the adjacentupright walls - In one embodiment of the invention, the plastics film that fixes the package is a two layer laminate comprising inner and outer layers suited to different purposes including allowing heat sealing of the film to itself, providing a suitable contact layer and protective film for the contents of the package, and providing a suitable external layer for printing and other packaging purposes. Typically, the outer layer may be orientated polypropylene OPP, orientated polyester OPET or orientated polyamide OPA, and the inner layer is polyethylene PE or non-orientated polypropylene PP. In other embodiments of the invention, a laminate film may be used having three or more layers.
- The line of
weakness 7 in the top wall 3 may be formed by perforations in the outer layer of the laminate film, these perforations being formed before the lamination of the inner and outer layers. The perforations are therefore sealed by the inner layer until the line of weakness is torn in opening the package. The plastics composition of the inner layer and its thickness are selected to facilitate the tearing process, and the composition of the material of the outer layer is also selected to ensure that the applied tension during the opening process is generally withstood until the line of weakness fails. In a typical example using polyethylene film, the inner layer may be 20-70 micron thick. Preferably, the polyethylene film is formulated to enable the laminate to be split more readily. For example, polyethylene films which ere blends of different polyethylene grades containing a proportion of medium or high density polyethylene have been found to be particularly suitable for this purpose. - The perforations in the line of
weakness 7 may be formed by any suitable means including mechanical or laser means. Laser perforation means may be used to form the perforations in a laminate film after lamination. - In an alternative embodiment of the invention, instead of providing perforations, a continuous slit may be provided in the outer layer.
- Furthermore, instead of a single line of
weakness 7 as shown inFIG. 1 , multiple parallel lines of weakness may be formed in the region of the centrefold of the top wall so as to allow for variation in the positioning of the centrefold of the package during the manufacturing process. That is, the multiple lines of weakness are preformed in the web that is eventually folded to form the side wall, and any lateral change in the position of the centre fold will then be accommodated by substantial alignment with at least one of the lines of weakness. The lines of weakness would typically be spaced 1 mm apart, - In an alternative embodiment of the invention, a monolayer film may be used for the packaging, and the line of weakness may be formed by means which still preserves the barrier properties of the top wall, for example, by local thinning of the thickness of the film along the line of weakness, or, if suitable for the contents, the line of weakness may involve perforations which penetrate the film and break the barrier properties of the top wall.
- In yet another embodiment of the Invention, the line of weakness or parallel lines of weakness are offset from the centre fold of the gusset towards the junction of the top wall 3 with a
side wall opposite side wall - In yet another embodiment of the invention, an opening may be provided in the top wall 3 by a line of weakness defining a portion of the wall which is to be displaced or removed on opening of the package. The line of weakness would then include portions that extend substantially laterally of the fold line of the top wall 3.
- In yet another embodiment of the invention, the line of weakness may be a cut in the top wall which is covered by a pressure sensitive adhesive label, the label being removed in order to create an opening in the top wall. The line of weakness may be formed by a die-cutting process.
- In any of the above embodiments of the invention, a reclose device such as a pressure sensitive adhesive label may be provided that can be used to close the opening, after it has been formed by tearing the line of weakness. This label may be attached to the top wall 3 to cover the line of weakness before it is torn, the label first being removed to allow the opening. Alternatively, the label may be attached to the packet elsewhere.
- In yet another embodiment of the invention, the top wall may he composed of an easy tear film which tears easily in a preferred direction, which direction would be aligned to extend between the two
upright seals FIG. 1 . - It will be appreciated that the terminology “top”, “bottom” and “side” as used in this application is not intended to be limitative, and that a package according to the invention may assume any orientation in use. However, it is a common practice to stack packages upright and to provide for them to be opened at the top as a matter of convenience.
