Definitions

  • This invention relates to a packaging having a closure lid adapted to provide easy access to a product contained in a bag used as refill. More specifically, the invention relates to a food packaging adapted to make installation of a gusset bag inside an outer container easier.
  • Gusset bags having a flexible side wall are well-known for containing a variety of products, especially flowable food products.
  • Refillable food pouches are known, for instance from WO 2014/120258 . But for air-sensitive contents, for example powdered milk or cereals, such kind of refillable pouch cannot be used.
  • gusset pouch Less sensitive food can also be supplied to a secondary market as a sealed gusset pouch or similar flexible bag.
  • Conventional gusset bags for this purpose are provided with two opposite gussets. After removal of a top portion, the gussets can unfold from a partially open configuration to a fully open configuration.
  • Such flexible bags (for example as disclosed in US 2011/0293208 ) are not well adapted for a pouring operation.
  • Rigid boxes are sometimes used to receive food content initially stored in flexible bags.
  • the box can be repeatedly filled up with such kind of food. But practically, loss of food product from a gusset bag or similar bag often occurs when pouring the flowable food content into the box.
  • boxes are not particularly well adapted to store a gusset bag that is in an open state because the product can flow between the flexible bag and the inner face of the box. This typically happens when the whole packaging is turned upside down in a closed state of the box. And if the box is not correctly closed by a lid positioned at the top of the box or if the sealing performed by the lid is not efficient, the product may be quickly altered and loss of product may occur.
  • Document WO 2012/085117 which accords with the preamble of claim 1, discloses a gusset bag stored in a box.
  • the box sidewall has an inner circumference adapted to guide the annular side of the bag, whereby the bag is standing in a predetermined position in the packaging. Because of the guiding by the box sidewall, the inner flexible bag cannot move laterally inside the container (fit of the bag inside the box). Such cooperation between an inner bag and an outer container, with a single predetermined position of the inner bag, is well-known in the art.
  • the gusset bag is provided with flaps that extend beyond the upper edges of the box.
  • a closure system In order to correctly close the top of the box, a closure system is provided with annular frame that accommodates the upper edges of the box with the flaps folded around these upper edges. Due to this accommodation, the gusset bag in the predetermined position is widely open and there is no leakage of product between the bag and the box sidewall, with provision that the flaps have been correctly folded and positioned.
  • JP2012197105A , JP2012197106A , JP2012197107A , JP2012197108A , JP2012197109A and JP2012197110A also relate to refillable food pouches that are maintained in a rigid box. At the top of the box, a specific insert is used to obtain a wide opening of the pouch and a cover can close the top access opening defined by the insert.
  • embodiments of the invention provide a packaging for a food product comprising:
  • the bag may fully cover the inner face of the bottom and is close to the sidewall of the outer container so as to be either in contact with the two opposite inner faces, or substantially coaxial with the sidewall of the outer container with a small gap at its periphery. More generally it is understood that the bag is sized so that it cannot move significantly in a radial direction, i.e. not more than 5 or 6 mm, preferably less than 4 mm, when put in a storage position in the interior volume. Such small play typically represents less than 9 or 10 percents of the width or equivalent size of the bag as the smaller size of the container is typically greater than 60 mm, preferably greater than 80 mm.
  • the insert part can efficiently come into contact and push (radially outwards) portions of the bag side wall when mounting the frame, thanks to the axial extensions, without interfering with unfolding of the bag, thanks to the notch.
  • the bag side wall has substantially the same shape has the container near the bottom, there is no particular requirement for any centering of the bag.
  • the top of the side wall of the bag has not to be particularly stretched or folded more than the reminder of the side wall, which is of interest to prevent undesirable cracks in the bag material.
  • the amount of plastic material to form the insert part is reduced as the notch typically defines a significant spacing between two axial extensions of a same side. This spacing may be superior to 30 mm near the free edges of the axial extensions.
  • the guiding axial extensions may be provided each with an angled free edge in order to guide each upper edges of the bag in a peripheral area that is defined between the insert part and the top of the container.
  • the bag is typically a gusseted pre-made bag so that planar outer faces in the side wall are easy to obtain, such outer faces matching with the corresponding inner faces of the container.
  • the wording "partially open configuration" may correspond to a free configuration where the opening is close to its size when the bag is configured in a fully open state.
  • the term “partially open” may simply be interpreted as “not fully open” (typically not sufficiently open to have a regular gap between the top of the bag and the container).
  • At least one of the two opposite inner faces is defined by a panel in contact with the upper fitment part and extends between two connections (preferably curved) that each define an angle, preferably of about 90°, between two adjacent panels of the sidewall of the outer container.
  • the sidewall of the outer container is defined by four panels interconnected at respective connections that extend each rectilinearly from the bottom to an angle of the peripheral upper rim, while the annular side wall of the bag is provided with four edges and has a predetermined periphery sized and shaped so that each of the edges is at less than about 3 mm from one of the connections when the bag is stored in the interior volume and the upper rim is engaged into a groove of the fitment part.
  • positioning the bag is intuitive and easy and the upper edges of the bag can be positioned as a lining that covers the inner face of the container sidewall. Since the bag is hold in a fully open state by the insert part (with the side wall of the bag thus longitudinally extending with a same small radial spacing with respect to the container), risk of folding the bag is prevented when retrieving the food content.
  • one of the axial guiding extensions extends between two notches from a base adjacent to a determined hole, such hole not intersected by the central axis being delimited by a part of the frame that is entirely covered by the lid in the closed configuration of the lid.
  • This determined hole is typically delimited by a retaining device for a measuring utensil and is preferably circular.
  • the axial guiding extension adjacent to the determined hole may optionally have a C-shape or L-shape section when viewed in a plane perpendicular to the central axis.
  • the notch extends between two planar portions of two axial extensions that are angled to have each a L-shape section when viewed in a plane perpendicular to the central axis.
  • This configuration of the axial extensions is well adapted to prevent undesirable folding (of the bag) near the angles of the outer container, especially when the packaging has a polygonal shape with angles of about 90°.
  • the insert part comprises four bridge portions each tapering toward the bottom with small deviation as compared to the central axis, said small deviation being preferably inferior or equal to 10°, each of the four bridge portions comprising:
  • the insert part is such that the following relation is satisfied: H ⁇ H 2 ⁇ 5 mm ⁇ H 1 where
  • a partly or fully transparent box could also advantageously be used with a satisfactory display of information marked on the outer faces of the bag side wall.
  • height of the bag may be lower, providing that the insert part is of greater height and/or the container is provided with one or more holding members or similar adjusting means for supporting the bag at a distance from the level of the bottom.
  • a packaging 1 including a box and a flexible gusset pouch or similar bag B that is not resealable (not tightly closed after removal of a top portion), the packaging being well adapted for easy retrieval of the food product contained in the bag B.
  • a variety of products may be contained in the bag B, preferably food products such as powdered milk, dry or powdered beverages, dry soups, coffee, tea, whey powder or the like, butter milk powder, spices, and other flowable solid food products.
  • the packaging 1 comprises a container 2 and a closure system 3.
  • the container 2 is open on one side opposite its bottom 20 and may be parallelepiped-shaped, provided with an oval section or any shape with a bottom substantially as wide as the opening, as those skilled in the art will understand.
  • An annular side wall 4 of the container 2 extends about a vertical central axis X to a top 2a defining a peripheral upper rim 21a.
  • An outer collar 2c may be provided and the top 2a may be defined as an annular projection protruding upwardly from an upper face defined by the collar 2c.
  • a wide opening 21 enclosed by a perimeter 22 is defined by the rim 21a that is rigid (the optional collar 2c increases rigidity of the rim 21a to prevent any deformation).
  • the cross section perpendicular to the central axis X of the container 2 may be basically rectangular with rounded corners. It ensures vertical strength of the packagings 1 when stacked.
  • Fig. 7 shows in more detail a way of stacking the packagings 1, using a recess at the bottom 20 to at least partly house the top wall 33 of the lid 32.
  • the cross section is preferably inscribed in a rectangle measuring 100 to 140 mm by 80 or 90 to 125 mm.
  • the interior volume V of the container 2 has a determined height H, which is here close to the whole height of the container 2.
  • the bottom 20 may be provided with bearing means 20a, for example feet or an annular base that may protrude downwardly with respect to the planar wall of the bottom 20. Such bearing means 20a can reinforce the strength of the bottom 20 when configured as an additional outer layer of the container 2.
  • the lower part 40 of the sidewall 4 may be of slightly narrower section as illustrated in Fig. 1 .
  • the determined height H here measured from a planar inner face F3 of the bottom 20 to the top face is preferably between 120 and 190 mm to provide the normal volume for boxes intended to contain infant powdered milk. It is therefore a relatively deep container whose opening 21 must be made as wide as possible to avoid difficulty with extracting powder from close to the bottom 20 of the container 2. In addition, this wide opening 21 allows a measuring utensil 100 to be used to pick up the powder or similar food content 5.
  • the perimeter 22 of the opening 21 of the container 2 may be considered to have a first long side 22a, an opposite second long side 22b, and first and second short sides 22c, 22d connecting the long sides.
  • Four corner portions or similar connections 6 may be defined in the sidewall 4 to prevent formation of sharp edges.
  • the four panels of the sidewall 4 are provided with four connections 6 each adapted for interconnecting two adjacent panels that form an angle of about 90°.
  • the container 2 may be made as a single thermally blow-moulded plastic component.
  • the plastic is preferably a multilayer composite forming a highly effective oxygen barrier where used for a food content 5 such as powdered milk, but the container 2 could of course be produced in some other material, especially metal or a multilayer cartonboard.
  • the food content 5 is stored in the bag B, which has a flexible side wall 8, a bottom 8a and a top portion defined by a closing band 10 intended to be cut or torn.
  • a front wall W1 and a rear wall W2 are interconnected by two opposite gussets 9a, 9b extending parallel to a longitudinal axis of the flexible side wall 8.
  • Welds or sealing junctions can be provided to define the bag B.
  • the closing band 10 may be a sealed part obtained by heat sealing.
  • the bottom 8a can be defined by flaps in an overlapped configuration with a sealing area defined between at least two flaps.
  • the bag B can be a mono-web construction of a film. But in preferred embodiments, the front wall W1, the rear wall W2 and the bottom 8a are obtained by assembling at least two different parts. In such case, the bag B includes several seal areas to seal the parts together (e.g., with heat-sealed parts). In a particular embodiment of the present invention as shown in Fig. 6 , the bottom 8a is deprived from any gusset and is typically planar. Each of the two gussets 9a, 9b has an interior edge extending between the respective inner faces of the front wall W1 and the rear wall W2 when the bag B is closed by the closing bad 10 or similar closing means.
  • the film material used to form the bag B can be plastic, such as low, medium or high density polyethylene, polypropylene, polyester (PET), polyamide or any other material that is commonly used in the packaging industry, copolymers, or blends thereof.
  • the film material can be a single layer cast or blown film, a multi-layer coextrusion or laminate.
  • the film material can also include one or more layers of paper, metal foil, vacuum deposited metal or inorganic layer of aluminium or silicon oxide and/or a polymer barrier layer, such as ethylene vinyl alcohol or polyvinylidene chloride. These examples are non limiting examples.
  • the material is flexible and capable of allowing a gusset 9a and/or 9b to be formed.
  • the two opposite gussets 9a, 9b are provided adjacent to the wide opening 11.
  • the bag B is therefore a gusset bag.
  • the upper end defined by the upper edges 7 is adapted to define an opening 11 substantially as wide as the bottom 8a, typically with the same shape as the bottom 8a.
  • the film is a multi-layer film, it is preferred that at least the inner layer of the bag B is a heat sealable layer.
  • the bag B is optionally provided with a top peripheral edge and, before a cutting or tearing or peeling action to remove such top part of the bag B, the content 5 of the bag B cannot be retrieved through the single opening 11 of the bag B.
  • the top portions of the front wall W1 and of the rear wall W2 are typically in an initial flat configuration, as illustrated in Fig. 6 .
  • the content 5 (powdered milk or other granular or powdery product for example) is perfectly preserved in the bag B until used for the first time when the top peripheral edge (here defined by the closing band 10) is removed, optionally with the aid of one or more peeling-off tongues, tearing tongues, weakened areas or the like.
  • the closing band 10 or similar top portion of the bag B is preferably provided with a line of weakness (at the dash line) that extends laterally across both walls W1 and W2 in close proximity to but below the top peripheral edge.
  • the line of weakness may be formed by, for example, perforating or scoring the front wall W1, the rear wall W2 and other optional flaps with a laser or knife either individually before these walls W1 and W2 are sealed together, or collectively after they have been sealed together.
  • One or both ends of line of weakness may terminate with a notch (not shown), which provides a stress concentration and aids in starting a tear along the line of weakness when the bag B is opened by a consumer.
  • the upper level of the food content 5 extends at an axial distance from the upper edges 7 that extend along a cut line that corresponds to the dash line (for example, the upper level is between 25 and 90 mm below the level of the edges 7).
  • the initial level of the food content 5, typically powder material corresponds to a height H3 that is significantly lower than a predetermined height H2 of the bag B when the bag B is in a fully open configuration (as shown in Fig. 4b for example).
  • the ratio H3:H2 may be comprised between 1:2 and 4:5 in some embodiments.
  • the bag B once open, can be stored in the interior volume V of the container 2.
  • the gusset bag B can also be stored in the container 2 and then opened by excising the closing band 10.
  • the interior volume V is here illustrated as fully matching with the outer shape of the container 2, it is understood that such interior volume V can be adjusted depending on specific configuration inside the container 2.
  • the height H2 of the bag B is inferior to the determined height H so that the upper rim 21a extends entirely above the upper edges 7 of the bag B.
  • the annular side wall 8 of the bag B has a shape matching with the sidewall 4 of the outer container 2 so as to prevent the bag B to be eccentrically positioned inside the interior volume V.

  • the annular transition part 38 can be radially connected to the fitment part 13 as shown in Fig. 8 , below the tight connection between the fitment part 13 and the upper rim 21a. Accordingly, the food content 5 cannot escape from the container 2 because of:
  • the frame 31 may comprise at least one resilient sealing element (not shown) more flexible than the axial extensions E1, E2, E3, E4 and protruding radially outwards from the outer faces F5, below the fitment part 13.
  • An annular gasket or similar annular resilient element which is preferably provided near the transition part 38 (and typically entirely above the notches 61, 62, 63, 64), defines one or more radial contacts between the bag B and the frame 31.
  • Such resilient element may be curved or angled to facilitate insertion of the insert part 35 through the opening 11.

  • the insert part 35 When mounting the closure system 3 with the bag B already extending in the interior volume V, the insert part 35 is sufficiently spaced from the container sidewall 4 to allow the upper edges 7 of the bag B to completely surround the skirt-like insert part 35 with a small play.
  • the guiding extensions E1, E2, E3, E4 are engaging, through the opening 11, the top of the bag B at opposite inner parts (corners or opposite sides).
  • each face of the side wall 8 of the bag B may be substantially planar. With this configuration, a wide and constant section of the bag B is obtained, which is optimal to retrieve food content 5 near the bottom 8a, using a measuring utensil 100.
  • the axial guiding extensions E1, E2, E3, E4 have a height H1 that is greater than length of the each of the two lower rectilinear edge portions defined at the free end (L-shaped free edge FE) of the guiding axial extension E1, E2, E3, E4.
  • Such height H1 may optionnally correspond to a maximum height of the insert part 31 and is typically comprised between 5 and 40 mm.
  • a polygonal shape with at least four angles for both the sidewall 4 and the side wall 8 of the bag B is preferred because the inner faces of the container 2 may be substantially planar and the axial guiding extensions E1, E2, E3, E4 may be each provided with one planar guiding section or two planar guiding sections 28, 29 configured with a L-shape when viewed in a plane perpendicular to the central axis (X).
  • the upper edges 7 defined at each side of the bag B are thus held in a substantially rectilinear position, without significant undulations in a transverse plane (no folding perceived by the user).
  • Angle of the L-shape may be not inferior to 90°, which is of interest to provide a guiding effect in two distinct directions by a same member of the insert part 35.
  • Each axial guiding extension E1, E2, E3, E4 is provided with a curved midsection 67 ( Fig. 4a ), which defines a radius of curvature much smaller than the radius of curvature at the connections 6 or at the ends of the shorts sides 31c, 31d.
  • the transition part 38 is longitudinally curved to be tangentially connected to the insert part 35 that has a small radial deviation as compared to the longitudinal axis X. But such small deviation is of interest to progressively increase the pressing toward the inner faces F1, F2 of the container sidewall 4. It can be seen that the axial extensions E1, E2, E3, E4 are each less slanted than the transition part 38.
  • the higher deviation of the transition part 38 and the substantially continuous curvature (with no horizontal surface) of the transition part 38 is here advantageous to prevent powder to accumulate on the transition part 38, i.e. out of the bag B.
  • the sidewall 4 of the container 2 is defined by four panels interconnected at the respective connections 6 that extend each rectilinearly from the bottom 20 to an angle 211, 212, 213, 214 of the peripheral upper rim 21a, as in the non-limiting embodiment of Fig. 1 .

  • the insert part 35 may comprise four bridge portions 66 interconnected by the axial guiding extensions E1, E2, E3, E4.
  • the insert part 35 defines four substantially planar outer faces F5.
  • Each of the bridge portions 66 (or similar notched part) tapers toward the bottom 20 with small deviation as compared to the direction of the central axis X. Such small deviation (see Figs 2 and 7 for instance) may be inferior or equal to 10°, preferably less than 4 or 5°.
  • extensions E1, E2, E3, E4 protrudes downwardly more than the arched midsections AS, they may deviate slightly more at the free edge FE (but typically with the same deviation angle) where the interspace D2 with the container 2 is maximum.
  • Such tapering is of interest because the gussets 9a and 9b can be here progressively moved toward the two opposite faces F1, F2, preferably planar, when the frame 31 is displaced proximate its fitted position and then fitted. More generally, it ensures a more progressive pressing effect in the opposite directions (toward the different sides 22a, 22b, 22c, 22d of the container 2).
  • Each of the four bridge portions 66 here comprises:
  • each arched section AS may define a midsection of one of the respective outer faces F5 of the insert part 35.
  • each midsection of the upper edges 7 (here it can be seen that at least the shorter sides have a V-profile before the pressing) is pressed only at the end or nearly the end of the mounting of the frame 31 and the upper edges 7 of the bag B may be held in a substantially rectilinear position, along the planar outer faces F5 at the end of the unfolding.
  • a first notch 61 and a second notch 62 are located opposite each other. These notches 61, 62 are preferably wider than high and the same applies for additional notches 63, 64 that extend along the long sides 22a, 22d.
  • the almost vertical configuration of the axial extensions E1, E2, E3, E4 is also advantageous because the insert part 35 does not obstruct the bag access. Only the optional retaining device 60 for receiving a measuring utensil 100 protrudes toward the central axis X, as shown in Figs 1-5 .
  • the bag B has an inner circumference provided with an initially energized annular elastic tape 65 (shown in Fig. 4a ) interfering with the gussets 9a, 9b and arranged near the upper end.

  • the axial extensions E1, E2, E3, E4 have the same profile in a cross section and have respective L-shaped free edges FE that all extend substantially in a same virtual transverse plane (horizontal plane in usual position of the packaging 1).
  • L-shaped free edges FE could be used, depending on the geometry of the container sidewall 4.
  • Providing at least two diametrically opposed L-shaped extensions or opposite L-shaped extensions along a virtual diagonal is of interest to define at least four distinct radiallly outward directions for the pressing against the inner faces of the bag B.
  • the opening 11 defined by the upper edges 7 of the bag B is expanded and the edges 7 are adequately positioned at a same axial level in the peripheral upper area around the insert part 35, entirely above the angled free edges FE and above the notches 61, 62, 63, 64 in the fitted configuration of the fitment part 13.
  • the small radial gap between the inner face of the container 2 and the upper half of the bag B is substantially constant because the upper edges 7 are not excessively stretched radially outwards.
  • the change of geometrical conformation as illustrated at the top of Figs 4a and 4b occurs at constant surface for the bag (no overstretching causing deformation of bag material).
  • the insert part 35 has a maximum height H1, which is of course lower than the determined height H of the interior volume V, and typically inferior to 30 mm. In preferred embodiments, the following relation is satisfied: H ⁇ H 2 ⁇ 5 mm ⁇ H 1 where H2 is the predetermined height of the flexible gusset bag B in the fully open configuration. Referring to Fig. 2 and 4b , such arrangement ensures that the upper edges 7 are in the upper part (which is narrower than the lower part with maximum radial distance D2) of the annular interspace defined between the insert part 35 and the corresponding inner face (for example the face F1 or F2) of the container 2.
  • the insert part 35 may be configured with a reduced number of notches and/or have a difference in height for at least one side of the insert part 35. More generally, the insert part 35 is provided with one or two notches 61, 62, defined between two of the axial guiding extensions E1, E2, E3, E4, and extending along one of the two opposite inner faces F1, F2 (here along the short sides 22c, 22d of the container 2).

  • Fig. 10 illustrates the fact that the shape of the container sidewall 4 is matching with the annular side wall 8 of the bag B.
  • the term "matching" means that the shape (form) is identical or sufficiently similar to prevent any unsuitable position where the side wall 8 of the bag B does not extend along the sidewall 4 of the container 2.
