Description
- The invention relates to a box-shaped package of a flexible and sealable, especially heat-sealable, packaging material including:
- a front wall and a back wall arranged opposite each another and sealed together along opposed side edges thereof by means transverse side seams;
- two opposed and inwardly folded end walls, a first end wall being sealed to the front wall and the back wall along first longitudinal end seams and along first end side seams adjacent a respective side seam and a second end wall being sealed to the front and the back walls along second longitudinal end seams and along second end side seams adjacent a respective side seam.
- The expression “packaging material” denotes both plastic film-based and paper-based materials and combinations thereof. Further the expression “film” is used in a wide sense to include a monofilm, a co-extruded film, and a laminate including one or more monofilms and or co-extruded films and optionally one or more paper layers.
- Packages of this type are inter alia known from WO 00/58166 and WO 00/58174. Such packages are preferably made of a web material on vertical form, fill and seal machines. Consequently, the expression “transverse” denotes a direction parallel to the longitudinal direction of the web material, said latter direction also being denoted as the machine direction. Correspondingly the expression “transverse” denotes a direction perpendicular to the machine direction. It should be noted that the packages may be made of a single web of packaging material or of several, eg two or four, packaging material webs. It should also be noted that the packages may be made as pre-fabricated bags, which are subsequently filled and sealed in a fill and seal machine.
- The object of the present invention is to provide a package of the above type, which is easily openable and may be provided with an advantageously sized opening allowing for easy access to and removal of the packed product. A special object of the invention is to provide a package for articles of foods, in particular light foods, such as mixed salads, the package being provided with a good sized opening allowing for use of the package as a bowl at consumption of the article of food contained therein.
- The package according to the invention is characterized in at least one of the side seams is peelable, that at least portions of the front and the back walls extend beyond the transverse peelable side seam to form a front wall gripping member and a back wall gripping member, and that opening means are provided for opening at least a portion of the front wall in longitudinal direction when the peelable sealing seam is peeled.
- The peelable side seam is peeled by gripping the gripping members or flaps of the front wall and the back wall and pulling these apart. At the same time due to opening means at least a portion of the front wall is opened to provide access to the interior of the package. The contents of the package may be removed through this opening, eg while the package rests on the back wall. It is thus possible to use the package as a bowl at consumption of the article of food contained therein.
- Further it should be noted that the present package differs from the above prior art packages in that the peelable side seam is a transverse seam when seen relative to the machine direction (MD in FIG. 1), whereas the peelable seams of the above prior art packages are longitudinal seams. This difference is considered advantageous in relation to the manufacture of the package and in relation to the properties of the package.
- According to a first embodiment of the invention a first and a second end side seam adjacent the peelable side seam are peelable at least between the front wall and the first and second end walls to optimize the provided opening. As a result the front wall is peelable along its entire transverse extent in the portion at the front wall gripping member.
- In the above embodiment of the invention the opening means advantageously includes peelable end seams between the front wall and the first and second end walls to allow for a complete removal of the front wall from the package, at least up to the side seam opposite the peelable side seam and the peelable end side seams. An opening is thus provided completely exposing the contents of the package to allow easy removal thereof.
- Furthermore according to the invention, the opening means may include two mutually interspaced incisions or weakening lines in the side edge of the front wall at the peelable side seam or at the peelable end side seams. When the gripping members are gripped and pulled apart, the front wall is peeled in the peelable side seam(s) and further torn longitudinally in line with the incisions or weakening lines, whereby an opening is provided in the front wall. The incisions or weakening lines may optionally extend into the peelable side seam(s).
- The above embodiment is particularly suitable when the packaging material includes a plastic film oriented in the longitudinal direction, ie in the machine direction, said oriented film providing a controlled tearing of the packaging material in line with the incisions or weakening lines, when the gripping members are gripped and pulled apart. Examples of such controlled and tearable films are oriented PE (polyethylene), PP (poly-propylene), PA (polyamide) and PET (polyester) films.
- Moreover, according to the invention the incisions or weakening lines may be provided at either of the end seams between the front wall and the first and the second end walls, respectively, to obtain as large an opening area as possible. It should be noted that the weakening lines may be formed by means of the sealing bars forming the longitudinal end seams between the front wall and the first and second end walls, the inner edges of the sealing bars weakening the packaging material at the inner edges of the longitudinal end seams. Differently stated the sealing bars provide a notch effect such that the packaging material is torn along the inner edges of the end seams, when the package is opened.
- According to another embodiment of the invention, the opening means include two mutually interspaced weakening lines in the front wall extending from a side edge thereof and beyond the peelable side seam or the peelable end side seams. When opening the package, the front wall is peeled in the peelable side seam(s) and further tom along the weakening lines. The weakening lines may advantageously be provided by means of so-called laser cuts, ie by means of a laser beam. The laser used may be a so-called contour laser, ie a laser capable of forming contoured, ie not straight, cuts. However, as well-known in the art the weakening lines may be formed by means of mechanical devices. The weakening lines may further be continuous or discontinuous.
- For an optimum control of the tearing action, in the longitudinal direction the weakening lines may extend over the majority of the front wall and preferably at least over two-thirds of the distance to the side seam opposite the peelable side seam.
- Furthermore, the weakening lines may be provided at either of the end seams between the front wall and the first and the second end walls and extend substantially parallel to the respective end seam to obtain as large an opening as possible.
- Moreover, according to the invention the weakening lines may be arranged symmetrically about a longitudinal centre line of the front wall and extend mutually diverging from the front wall gripping member towards the end seams and then parallel thereto.
- The weakening lines may further extend so as to allow a joining thereof, eg they may initially extend parallel to each other and then mutually divergent. As a result the portion of the front wall defined by the weakening lines may be removed completely at opening of the package.
- Finally, according to the invention in transverse direction the gripping members may have an extent less than that of the package and be arranged centrally. However, it is to be understood that the front wall and the back wall over their entire transverse width may extend beyond the peelable side seams, whereby the gripping members or flaps may have a transverse width corresponding to the transverse width of the package. Optionally the front wall member may be defined by two mutually interspaced incisions or weakening lines in the projecting portion of the front wall.
- The expression “peelable” denotes a seal or a seam, which may be peeled and which preferably has a strength between 100 and 800 g/20 mm, most preferably between 200 and 500 g/20 mm.
- Peelable sealing seams may for instance be provided by using a sealing medium sealing peelably to itself. The sealing medium may either be a film, eg a so-called peel PE or peel PP (cast PP), or a coating which may be applied either to the entire inner surface or only to the sealing areas. Another option is to apply a coating, eg a so-called peel lacquer, to a sealing medium fushion-sealing to itself, said coating weakening the sealing strength so as to provide a peel seal. Such weakening coatings may be applied by printing either to the entire inner surface or only to the sealing areas. A third option for providing a peelable seal is to use a laminate or a co-extruded film including a thin inner sealing medium layer, and a superjacent layer, the peel strength between the said layers being lower than the sealing strength obtained when the sealing medium is heat-sealed to itself. A peeling of the seal causes a tearing of the thin inner sealing layer along the edges of the sealing seam and a delamination between the two layers of the laminate or co-extrudate in the area of the sealing seam. The above peelable seal is also known as a so-called riss peel.
- In a modification of the above riss peel, a pressure-sensitive layer, eg a hot-melt, is provided between the above thin inner sealing medium layer and a subjacent layer, the peel strength between the inner layer and the pressure-sensitive layer being lower than the sealing strength obtained when the inner sealing medium layer is sealed to itself. Optionally the inner cohesion of the pressure-sensitive layer is less than the peel strength between the pressure-sensitive layer and the inner sealing medium layer and the sealing strength obtained when the sealing medium layer is sealed to itself. A peeling of the seal causes a tearing of the thin inner sealing medium layer along the edges of the sealing seam and a delamination between the inner sealing medium layer and the pressure-sensitive layer or optionally an inner delamination or splitting of the pressure-sensitive layer. Thus, the pressure-sensitive layer is exposed, when the seal is peeled and may be used for reclosure of the package after the initial opening thereof.
- The invention is explained in details below with reference to the accompanying drawings, in which
- FIG. 1 is an isometric view of a first embodiment of a box-shaped package according to the invention, shown in its closed state,
- FIG. 2 illustrates the package shown in FIG. 1 in its open state,
- FIG. 3 is a view corresponding to FIG. 1 of a modification of the first embodiment shown in FIGS. 1 and 2,
- FIG. 4 is an isometric view of a second embodiment of a box-shaped package according to the invention in its closed state, and
- FIG. 5 illustrates the package shown in FIG. 4 in its open state.
- The embodiment of a box-shaped package according to the invention shown in FIGS. 1 and 2 includes a
front wall 1 and aback wall 2 arranged opposite each other and opposing first andsecond end walls front wall 1 and theback wall 2 are sealed together inner face to inner face alongtransverse side seams 5, 6 extending along opposing side edges. - The
first end wall 3 is folded inwards at theend portions front wall 1 and theback wall 2 along transversefirst end seams end portions first end wall 3 is sealed to itself outer face to outer face and to thefront wall 1 and theback wall 2 inner face to inner face along first opposing end side seams 11, 12. Thus the inwardly foldedend portions first end wall 3 are sandwiched between the front andback walls transverse side seams 5, 6 between thefront wall 1 and theback wall 2. - The
second end wall 4 is also folded inwards at theend portions front wall 1 and theback wall 2 along second transverse end side seams 15, 16. In the inwardly foldedend portions second end wall 4 is sealed to itself outer face to outer face and to thefront wall 1 and theback wall 2 inner face to inner face along second opposing end side seams 17, 18. As a result, the inwardly foldedend portions second end wall 3 are sandwiched between thefront wall 1 and theback wall 2 at the second end side seams 17, 18. The end side seams 17, 18 are aligned with thetransverse side seams 5, 6 between thefront wall 1 and theback wall 2. - In the side seams portion the
front wall 1 and theback wall 2 are extended in the longitudinal direction such that they extend beyond theside seam 5 to form a frontwall gripping member 19 and a backwall gripping member 20. Theside seam 5 is a peelable seam. The adjacent end side seams 11 and 17 between thefront wall 1 and the first andsecond end walls longitudinal end seams front wall 1 and theend walls wall gripping member 19 and the backwall gripping member 20 are gripped and pulled away from one another, thepeelable side seam 5, the peelable end side seams 11, 17 between thefront wall 1 and theend walls peelable end seams end walls front wall 1 is peeled, the end side seams 11, 17 remain intact, ie. are left non-peeled, in the sealing areas between theback wall 2 and the inwardly foldedend portions end walls portions - In a modification of the above embodiment instead of being arranged centrally, the gripping
members - An example of a suitable packaging material for the above embodiment is the laminate coex. OPP/peel PE, wherein peel PE is a polyethylene-based sealing medium layer sealing peelably to itself and coex. OPP denotes a co-extruded oriented polypropylene film provided with a thin sealing medium layer on each side including a copolymer of PP and PE. The peel PE film is the inner layer when seen in relation to the finished packaging. The thickness of the coex. OPP film may for instance be 60 μm and the thickness of the peel PE film may for instance be 20 μm. In order to obtain improved barrier properties, one or more barrier layers, eg of polyvinylidene chloride (PVdC) or of ethylenevinyl alcohol (EVOH) or a metallization layer, may be provided between the peel PE film and the coex. OPP film.
- The package may advantageous be manufactured and filled on a vertical form, fill and seal machine, preferably from a single web of packaging material. By this manufacturing method the web material is fed into the machine's filling tube having a rectangular cross section and is formed into a hose of a rectangular cross section, three of the end seams being formed by folding and sealing the web material, while the fourth end seam is formed by sealing the edges of the web material.
- The fourth end seam may for instance be the
end seam 9 between thefront wall 1 and thefirst end wall 3. Since the web material is continuous at the three folded and sealed end edges, the fold at theend seam 15 opposite theend seam 9 has to be cut away in the longitudinal direction to allow for peeling of theend seam 15 between thefront wall 1 and thesecond end wall 4, when the finished package is to be opened. The removal of the said fold may advantageously be performed on the filling tube immediately after completion of theend seam 15. - The
transverse side seams portions end portions end walls transverse side seams members - The second embodiment of the invention shown in FIGS. 4 and 5 corresponds widely to the first embodiment shown in FIGS. 1 and 2 and thus includes a
front wall 1 and aback wall 2 being sealed together by means oftransverse side seams 5, 6, and first andsecond end walls end portions first end wall 3 is sealed to the front andback walls longitudinal end seams second end wall 4 is sealed to the front andback walls gripping members side seam 5. In respect of the above the second embodiment shown in FIGS. 4 and 5 is identical to the first embodiment shown in FIGS. 1 and 2. - However, the second embodiment differs from the first embodiment by the
front wall 1 being provided with two mutually interspaced,longitudinal weakening lines 21, 22 weakening the packaging material to such an extent that it is torn along the weakening lines, when subjected to a predetermined tear force. The weakening lines 21, 22 are provided adjacent arespective end seam front wall 1 and the first andsecond end walls free end edge 23 of thefront wall 1 over the majority of thefront wall 1 in the longitudinal direction. - For opening the package the gripping
members peelable side seam 5 is peeled. Furthermore the adjacent peelable end side seams 11, 17 between thefront wall 1 and the first andsecond end walls front wall 1 and theend walls - The same packaging materials may be used for the above embodiment as used for the first embodiment. Since the end seams9, 10 are not peeled when the package is opened, a packaging material having an inner sealing medium layer, which fusion-seals, ie. it does not seal peelably to itself, may, however, also be used provided that a
peelable side seam 5 is provided between the front andback walls front wall 1 and theend walls peelable side seams front wall 1 and theend walls end seam 15 need not be cut away during the manufacture of the package from a single web of packaging material on a vertical form, fill and seal machine. - It should further be noted that instead of being rectilinear the weakening lines may extend mutually diverging from the front
wall gripping member 19 towards the end seams 9, 15 and then extend mutually parallel thereto, as shown by means of dot-and-dash lines transverse weakening line 27, as shown in FIG. 4. As a result, the portion of thefront wall 1 defined by the weakening lines 25, 26, 27 is removed completely when the package is opened. - Finally, if an easily controlled tearable packaging material is used for the package, such as most oriented films, weakening lines may be omitted in the embodiment shown in FIGS. 4 and 5. The front wall may instead be provided with two mutually inter-spaced incisions or weakening lines in the
free side edge 23 at thepeelable side seams peelable side seams - While the invention has been described in details above with reference to heat-sealable plastic films, it should be understood that the present invention is not restricted to the use of such films. Thus, the present invention also includes the use of paper-based heat-sealable materials and the use of plastic film-based and paper-based cold-sealable materials.
