Definitions

• the present invention relates to an apparatus and to a production method for producing a sealed single-dose break-open package.
• the patent application W02008038074A2 describes a sealed single-dose break- open package; the sealed package comprises a sheet of semi-rigid plastic material and a sheet of flexible plastic material which is superposed on and sealed to the sheet of semi-rigid plastic material to form a sealed pocket that contains a dose of a fluid product.
• the sheet of semi-rigid plastic material has in the central part a weakened zone for guiding controlled breakage of the sheet of semi-rigid plastic material in such a way as to cause the formation of an outlet opening for the product through the sheet of semi-rigid plastic material itself.
• the weakened zone comprises an inner incision that is made through an inner surface (that is, facing the pocket) of the sheet of semi-rigid plastic material and an outer incision that is made through an outer surface of the sheet of semi-rigid plastic material and aligned with the inner incision.
• the sealed single-dose package described in patent application W02008038074A2 does not allow to apply (spread) the product contained inside the package itself in a precise and intuitive manner on a surface and therefore that package is not suitable to contain spreadable products (that is, to be spread on a surface).
• patent application W02008038074A2 describes the use of an apparatus including a reel for feeding a strip of semi-rigid material and a reel for feeding a strip of flexible material, an incision unit and a package forming station including a device for feeding the fluid product and a sealing device.
• the incision unit has two parallel, facing plates, movable towards each other to grip the strip of semi-rigid material, that support some blades. Each plate is pushed towards the other respectively by a linear actuator in order to hold the strip of semi-rigid material and make an incision on each side of the same.
• a“V”-shaped incision that varies in depth is made on each side of the strip of semi-rigid plastic material, with a sharper blade on the side of the strip intended for the outer part of the package.
• the blades are pushed one against the other in order to hold the strip of semi-rigid material and make the incisions on the same. Even through this method, moving the blades turns out to be difficult and it is not possible to control the depth of the incision.
• the object of the present invention is to provide an apparatus and a method for producing a sealed single-dose break-open package that are free from the above mentioned disadvantages.

• the sealed single-dose package 1 comprises a rectangular sheet 2 of semi-rigid plastic material and a rectangular sheet 3 of flexible plastic material superposed on and sealed to sheet 2 of semi-rigid plastic material to form (between sheets 2 and 3) a sealed pocket 4 containing a dose of a fluid product 5.
• the sheet 2 of semi-rigid plastic material may have regular or irregular shape and sheet 3 of flexible plastic material may have regular or irregular shape symmetric to the semi-rigid plastic material.
• the sheet 2 of semi-rigid plastic material has a weakened zone 6 in the central part for guiding controlled breakage of the sheet 2 of semi-rigid plastic material in such a way as to cause the formation of an outlet opening for the product 5 through the sheet 2 of semi-rigid plastic material.
• a user has to grip the sealed single-dose package 1 with the fingers of one hand and“V”-bend (as shown in figure 3) the sealed single-dose package 1 until the sheet 2 of semi-rigid plastic material breaks at the weakened zone 6.
• the product 5 can flow smoothly and hygienically out of the sealed single-dose package 1.
• the weakened zone 6 comprises one inner incision 7 (not passing through, i.e. it does not go completely through the sheet 2 of semi-rigid plastic material) which is made through an inner surface 8 (that is, oriented towards pocket 4 or facing pocket 4) of the sheet 2 of semi-rigid plastic material and a outer incision 9 (not passing through, i.e. it does not go completely through the sheet 2 of semi-rigid plastic material) that is made through an outer surface 10 (that is, opposite to pocket 4) of the sheet 2 of semi-rigid plastic material.
• the two incisions 7 and 9 are identical (that is, shape and dimensions of the inner incision 7 are equal to the shape and dimensions of the outer incision 9), aligned and superposed (that is, the two incisions 7 and 9 are placed exactly in the same position on the opposite surfaces 8 and 10 of the sheet 2 of semi-rigid plastic material).
• the two incisions 7 and 9 do not touch, that is, a residual portion of the sheet 2 of semi-rigid plastic material interposes itself between the two incisions 7 and 9, to preserve the integrity of sealed pocket 4.
• the sheet 2 of semirigid plastic material and the sheet 3 of flexible plastic material in this example of embodiment are made in such a way that incisions 7 and 9 determine the required breakage of the sheet 2 of semi-rigid plastic material when exposed to the forces generated by the“V”-bending (shown in figure 3).
• the sheet 2 of semi-rigid plastic material is a laminate and includes an outer supporting layer 1 1 (that is, on the side opposite to pocket 4 in the area of the outer surface 10) and an inner supporting layer 12 (that is, on the side of pocket 4 in the area of the inner surface 8).
• An insulating or barrier layer 13 is provided between the two supporting layer 1 1 and 12 to ensure impermeability to air and/or light; in other words, the barrier layer 13 is enclosed by the two supporting layers 11 and 12 and separates the supporting layers 1 1 and 12 itself from one another.
• the supporting layer 12 is covered by a heat-sealable layer 14 which is placed internally (that is, on the same side of pocket 4 and in contact with sheet 3 of flexible plastic material to allow the heat-sealing to the sheet 3 of flexible plastic material itself).
• the two supporting layers 11 and 12 may have the same thickness (i.e. are specular or twins); however, according to other embodiments, the two supporting layers 1 1 and 12 may have different thicknesses, i.e. the thickness of supporting layer 1 1 is different from thickness of supporting layer 12.
• the sheet 2 of semi-rigid plastic material may be composed of: a supporting layer 1 1 of white polystyrene (PS) with a thickness of 200 micron ( ⁇ 10%), a barrier layer 13 of“Evoh” or dialuminium with a thickness of 10 micron ( ⁇ 10%), a supporting layer 12 of white polystyrene (PS) with a thickness of 200 micron ( ⁇ 10%), and a heat-sealable layer 14 of polyethylene (PE) with a thickness of 50 micron ( ⁇ 10%).
• supporting layers 1 1 and 12 may be composed of polylactic acid (PLA) preferably biaxially oriented, and/or the heat-sealable layer 14 may be composed of polypropylene (PP).
• Polylactic acid (PLA) is generally heat-sealable, therefore when supporting layers 11 and 12 are made of polylactic acid (PLA), heat-sealable layer 14 may be absent since the sheet 3 of flexible plastic material may be heat-sealed directly to supporting layer 12 of polylactic acid (PLA). Moreover, when supporting layers 1 1 and 12 are made of polylactic acid (PLA) or polypropylene (PP), it is possible to reduce the thickness of the supporting layers 1 1 and 12 itself since polylactic acid (PLA) and polypropylene (PP) allow to obtain sufficiently rigid supporting layers 1 1 and 12 even with a small thickness.
• supporting layers 1 1 and 12 are made of polystyrene (PS)
• the overall thickness of supporting layers 1 1 and 12 has to be higher than 350-380 micron
• supporting layers 1 1 and 12 are made of polylactic acid (PLA) or polypropylene (PP)
• the overall thickness of supporting layers 1 1 and 12 may reach even 200 micron.
• Each incision 7 or 9 has on the surface (i.e. at the surface of the corresponding supporting layer 11 or 12) a width W that may vary according to the plastic material used to make the supporting layers 11 and 12: with white polystyrene (PS) the width W of each incision 7 or 9 may range between 0,5 e 1,5 mm while with biaxially oriented polylactic acid (PLA) or with polypropylene (PP) the width W of each incision 7 or 9 may range between 2 and 4 mm.
• the width W of each incision 7 or 9 when using biaxially oriented polylactic acid (PLA) or polypropylene (PP) is higher than the width W of each incision 7 or 9 when using polystyrene (PS).
• the outer incision 9 is made through the outer surface 10 of the sheet 2 of semirigid plastic material and can be made by deforming locally the sheet 2 of semirigid plastic material and in particular the supporting layer 11 of the sheet 2 of semi-rigid plastic material; the outer incision 9 ends before the barrier layer 13 and therefore it does not affect the barrier layer 13 itself.
• the inner incision 7 is made in the inner surface 8 of the sheet 2 of semi-rigid plastic material and can be executed by deforming locally the sheet 2 of semi rigid plastic material and in particular the supporting layer 12 of the sheet 2 of semi-rigid plastic material; the inner incision 7 ends before the barrier layer 13 and therefore it does not affect the barrier layer 13 itself.
• the heat-sealable layer 14 can be deformed or torn (partially or completely); in any case, at the inner incision 7 there is no sealing of any kind between the sheet 2 of semi-rigid plastic material and the sheet 3 of flexible plastic material and therefore the possible local damage of the heat- sealable layer 14 does not have any consequence.
• the incision 7 is made only on the inner surface 8 of the sheet 2 of semi-rigid plastic material by deforming locally the sheet 2 of semi rigid plastic material and in particular the supporting layer 12 of the sheet 2 of semi-rigid plastic material; the inner incision 7 ends before the barrier layer 13 and therefore it does not affect the barrier layer 13 itself (figure 1 1).
• the barrier layer 13 may be located between the two supporting layers 1 1 and 12 to build a barrier for the product inside the sealed pocket 4.
• the incisions 7 and 9 may not affect the barrier layer 13.
• the barrier layer 13 may be thick and solid enough to allow a partial penetration of incisions 7 and 9 provided that the barrier layer 13 is designed to maintain its barrier function.
• the integrity of barrier layer 13 of the sheet 2 of semi-rigid plastic material secures the barrier function and therefore the tightness for the content of the sealed pocket 4 even in the area of the incisions 7 and 9 and therefore the sealed pocket 4 is suitable to contain also perishable products and/or with controlled bacterial load like food, medicines or cosmetics.
• inner incision 7 and outer incision 9 may have an essentially constant depth lengthwise (net of the inevitable construction tolerances).
• each incision 7 and 9 (the two incisions 7 and 9 are identical to and superposed on each other and therefore not distinguishable in figure 5) develops along a single line with broken shape (i.e. a single zig-zag line), that is a line composed of an ordered set of consecutive oriented segments (i.e. such that the second end of a segment matches with the first end of the following segment) and not adjacent (i.e. such that a segment and the following segment do not belong to the same straight line).
• each incision 7 and 9 develops along a single line with broken shape (i.e. a single zig-zag line) that is open (i.e.
• the segments of the single line with broken shape (i.e. a zig-zag single line) along which incisions 7 and 9 develop are essentially parallel or essentially perpendicular and therefore a segment forms always an essentially right angle with the next segment.
• Each incision 7 and 9 has a“U”-shaped central part 15 and two lateral parts 16 that are placed on the opposite sides of the central part 15 and connected to the central part 15 itself.
• the two lateral parts 16 are constituted of two respective straight line segments that have identical dimension and are aligned with each other (i.e. one lies on the extension of the other).
• the central part is constituted of a main segment 17 that is essentially parallel to and offset from (i.e. not aligned) the two lateral parts 16 and of two joining segments 18 that are essentially parallel to and offset from each other (i.e.
• each incision 7 and 9 has a square“W” shape (i.e. constituted only of segments essentially parallel or essentially perpendicular to each other).
• the weakened zone 6 does not affect the whole width of the sheet 2 of semi-rigid plastic material, but affects only a central portion of the sheet 2 of semi-rigid plastic material leaving intact (i.e. without the weakened zone 6) two lateral portions of the sheet 2 of semi-rigid plastic material symmetrically placed on opposite sides of the weakened zone 6 itself.
• the weakened zone 6 increases as the density of the product 5 contained in the pocket 4 of the sealed single-dose package 1 increases, that is, the weakened zone 6 (i.e. the two superposed incisions 7 and 9) decreases as the density of the product 5 contained in the pocket 4 of the sealed single-dose package 1 decreases.
• the embodiment shown in figure 5 can be suitable to products with a higher density such as creams or granular products while the embodiment shown in figure 6 can be suitable to products with a lower density like liquids.
• the main segment 17 can be linear, angled (broken) or curved.
• lateral parts 16 or joining segments 18 can be linear, angled (broken) or curved.
• the incisions 7 and 9 are made by means of plastic deformation of the material using corresponding incision tools 19, each of them having a tip that is not sharp, that is to say, that has a round shape (namely a rounded tip) for deforming rather than cutting the supporting layers 1 1 and 12 of the sheet 2 of semi-rigid plastic material.
• only one incision 7 is made on the inner surface 8 of the sheet 2 of semi-rigid plastic material by deforming locally the sheet 2 of semi-rigid plastic material and in particular the supporting layer 12 of the sheet 2 of semi-rigid plastic material; by means of an incision tool 19 having a tip that is not sharp, that is to say, that has a round shape (namely a rounded tip).
• the tip may have different degrees of sharpness and may have any shape according to the product contained in the package.
• the sealed single-dose package 1 has a rectangular shape; obviously due to aesthetic reasons the sealed single-dose package 1 may be shaped differently: rounded, elliptic,“bottle”-shaped, rhomboidal, pentagonal, hexagonal, triangular, squared, “bone”-shaped.
• the sealed single-dose package 1 described above has numerous advantages. Firstly, the sealed single-dose package 1 described above is easier and cheaper to produce than a similar known package 1 (for example of the type described in patent application W02008038074A2), since the incisions 7 and 9 have a constant depth and therefore are easier to be made even with high operating speed.
• the package 1 described above allows to dose in a simple and efficient way all kind of fluid (liquid or creamy), powdered or granular products and it is particularly suitable for spreading the product 5 on a surface thanks to the area of the sheet 2 of semi-rigid plastic material enclosed by the central part 15 of the incisions 7 ad 9 that can be separated (moved) from the rest of sheet 2 of semi- rigid plastic material becoming a spatula useful to spread the product 5 itself.
• the central portion on the main segment 17, between joining segments 18 is designed to extend when package 1 is V-bended, in a trajectory beyond the adjacent structures of the sheet 2 of semi-rigid plastic material to work as a scoop for spreading the product that comes out from the opening (as shown in figure 3).
