• the sealed package 1 comprises a substantially rectangular sheet 2 of semi-rigid plastic material (visible in Figures 1 and 2) and a substantially rectangular sheet 3 of flexible plastic material (only visible in Figure 1), which is superimposed on and sealed to the sheet 2 of semi-rigid plastic material to define a sealed pocket 4 that contains a dose of a (preferably liquid) fluid product 5.
• the sheet 2 of semi-rigid plastic material has longer sides that extend in a longitudinal direction D1 and shorter sides that extend in a transverse (lateral) direction D2.
• the fluid product 5 may be, or may include, a vaporizable solution such as an "e-liquid" (i.e. a liquid for electronic cigarettes) .
• the fluid product 5 may include nicotine, propylene glycol, glycerine, water, and/or flavorings (natural and/or artificial) .
• the fluid product 5 may, additionally or alternatively, contain one or more non-nicotine stimulants and/or other suitable ingredients .
• the sheet 2 of semi-rigid plastic material has a centrally located pre-weakened area 6 (visible in Figure 2), which is created in a central area of the sheet 2 of semi-rigid plastic material (in particular in a longitudinally central area) , extending transversely (i.e. parallel to the shorter sides of the sheet 2 of semi-rigid plastic material) , and guides a controlled breakage of the sheet 2 of semi-rigid plastic material so as to cause the formation of an outlet opening for the (preferably liquid) product 5 through the sheet 2 of semi rigid plastic material.
• a user grasps the sealed package 1 with the fingers of one hand and bends the sealed package 1 in a "V" shape until the sheet 2 of semi-rigid plastic material breaks at the pre-weakened area
• the sheet 2 of semi-rigid plastic material has a U-shaped protuberance 7 that extends in the transverse direction D2 from a longer side of the sheet 2 of semi-rigid plastic material and is located at the pre weakened area 6, or rather, it is aligned (centred) with the pre-weakened area 6.
• the illustrative protuberance 7 includes two concave portions 16 that extend laterally from an outer edge of a main body 17 of the sheet 2 and meet at a convex portion 18 of the protuberance
• the protuberance 7 may be otherwise shaped.
• the protuberance 7 may include two portions 16 that meet at a most laterally protruding point of the protuberance 7.
• the protuberance 7 may include one or more rectangular, or otherwise shaped, bodies that extend laterally from the outer edge of the main body 17.
• the sheet 3 of flexible plastic material is without the protuberance 7 (i.e. the sheet 3 does not extend into the protuberance 7); in consequence, the sheet 3 of flexible plastic material is shaped slightly different from (i.e. not completely superimposable on) the sheet 2 of semi-rigid plastic material in the illustrative embodiment.
• the sheet 3 of flexible plastic material also has the protuberance 7 (i.e. similar to the sheet 2, the sheet 3 also extends into the protuberance 7); in such embodiments, the sheet 3 of flexible plastic material is shaped to be completely superimposable on the sheet 2 of semi-rigid plastic material.
• the illustrative protuberance 7 extends a length L (measured along the longitudinal direction Dl) of approximately 9-10 mm from the outer edge of the main body 17 of the sheet 2 and has a maximum width W (measured along the transverse direction D2) of approximately 25 mm.
• the protuberance 7 may have other dimensions in other embodiments .
• the pre-weakened area 6 comprises two external incisions 8 and 9, which are aligned with each other, separated from each other (i.e. there is a non-zero lateral distance between the two external incisions 8 and 9) , are oriented parallel to the transverse direction D2 and transversely relative to the length of the package 1 (e.g. shown as being parallel to the shorter sides of the sheet 2 of semi-rigid plastic material) , and are made in an outer surface 10 (i.e. opposite an internal surface 12 that defines the pocket 4) of the sheet 2 of semi-rigid plastic material.
• External incision 8 is opposite to the protuberance 7 (and so at a certain distance from the protuberance 7), while external incision 9 is next to the protuberance 7 and also extends along the protuberance 7 (i.e. it occupies the protuberance 7 and extends up to an outer edge of the protuberance 7); moreover, in addition to extending on one side along the protuberance 7, external incision 9 also extends with its other side over the pocket 4 (i.e. part of external incision 9 opposite to the protuberance 7 overlaps the pocket 4) .
• the pre-weakened area 6 comprises an internal incision 11 that is transversely oriented (i.e. parallel to the transverse direction D2), is parallel to and aligned with (e.g. within the same plane of) external incision 9, and is made in an inner surface 12 (i.e. facing towards the pocket 4) of the sheet 2 of semi-rigid plastic material opposite to the outer surface 10.
• the internal incision 11 only extends over the pocket 4 (i.e. the internal incision 11 is entirely superimposed on the pocket 4) and only over external incision 9 (i.e. the internal incision 11 is entirely superimposed on external incision 9) .
• the illustrative internal incision 11 does not extend laterally beyond the edge of the pocket 4.
• the internal incision 11 only extends in an area where both the pocket 4 (on the side of the inner surface 12 of the sheet 2 of semi-rigid plastic material) and external incision 9 (on the side of the outer surface 10 of the sheet 2 of semi-rigid plastic material) are present.
• the sheet 2 of semi-rigid plastic material is constituted by a laminate comprising a supporting layer 13 arranged externally (i.e. on the opposite side to the pocket 4 and at the outer surface 10) and a heat-sealable layer 14 arranged internally (i.e. on the same side as the pocket 4, and at the inner surface 12, and in contact with the sheet 3 of flexible plastic material at the periphery of the pocket 4) .
• the sheet 2 of semi-rigid plastic material could be composed of a white polystyrene (PS) supporting layer 13 having a thickness of 400 micron ( ⁇ 10%), of an "Evoh” or aluminium barrier layer 15 having a thickness of 7 micron ( ⁇ 10%), and a polyethylene (PE) heat-sealable layer 14 having a thickness of 43 micron ( ⁇ 10%) .
• PS white polystyrene
• PE polyethylene
• the sheet 2 may be composed of one or more other suitable types of materials having suitable dimensions consistent with the functions described herein .
• the illustrative external incisions 8 and 9 are made in the outer surface 10 of the sheet 2 of semi-rigid plastic material, have a V-shaped cross-section, and are made by locally deforming the sheet 2 of semi-rigid plastic material; according to a preferred embodiment shown in the accompanying figures, the external incisions 8 and 9 are made by deforming only the supporting layer 13 of the sheet 2 of semi-rigid plastic material, i.e. the external incisions 8 and 9 only occupy the supporting layer 13 of the sheet 2 of semi-rigid plastic material. In other embodiments, the external incisions 8 and 9 may have an otherwise shaped cross-section (e.g. a U-shaped cross-section) .
• the illustrative internal incision 11 is made in the inner surface 12 of the sheet 2 of semi-rigid plastic material, has a V-shaped cross-section, and is made by locally deforming the sheet 2 of semi-rigid plastic material; according to a preferred embodiment shown in the accompanying figures, the internal incision 11 is made by deforming all three of the supporting 13, heat-sealable 14 and barrier 15 layers of the sheet 2 of semi rigid plastic material. In other embodiments, the internal incision 11 may have an otherwise shaped cross-section (e.g. a U-shaped cross-section) .
• the heat-sealable layer 14 and especially the barrier layer 15 of the sheet 2 of semi-rigid plastic material are locally deformed (even in an irregular manner) along the internal incision 11, but are not torn, i.e. they are still integral .
• the barrier layer 15 of the sheet 2 of semi-rigid plastic material also along the internal incision 11 made in the inner surface 12 of the sheet 2 of semi-rigid plastic material, it is possible to ensure the substantial insulation (e.g. food- or medical-grade insulation) of the pocket 4, which is thus suitable for also containing perishable products and/or products with controlled bacteria counts such as foods, medicines or cosmetics.
• External incision 9 in the portion superimposed on the internal incision 11 and the internal incision 11 serve to cause the controlled breakage of the sheet 2 of semi-rigid plastic material when the sealed package 1 is bent in a "V" shape, to allow dispensing of the product 5 contained in the pocket 4.
• External incision 9 in particular, in the portion not superimposed on the internal incision 11 also serves to guide folding the sheet 2 of semi-rigid plastic material in a "V" shape in such a way that the vertex of the "V” shaped fold in the sheet 2 of semi-rigid plastic material coincides with the incisions 8, 9 and 11.
• External incision 9 (in the portion not superimposed on the internal incision 11 and extending along the protuberance 7) also serves to guide the product 5 coming out through the fractured sheet 2 of semi-rigid plastic material in such a way that the product 5 runs across the entire protuberance 7 along external incision 9 until it leaves the protuberance 7 (and therefore the sheet 2 of semi-rigid plastic material and the sealed package 1) from the central area (where external incision 9 is located) of the protuberance 7.
• the protuberance 7 allows for highly controlled dispensing of the product 5.
• External incision 8 (as it is on the opposite side to the protuberance 7 and is not superimposed on the internal incision 11) only serves to guide folding the sheet 2 of semi-rigid plastic material in a "V" shape in such a way that the vertex of the "V" shaped fold in the sheet 2 of semi-rigid plastic material coincides with the incisions 8, 9 and 11.
• external incision 8 is not provided (or rather, only external incision 9 and the internal incision 11 are provided) .
• external incision 9 does not extend along the entire protuberance 7, but stops before the protuberance 7 or only occupies part of the protuberance 7.
• external incision 9 is connected to external incision 8 without any interruption; or rather, the two external incisions 8 and 9 together form a single external incision that occupies the entire transverse extension of the sheet 2 of semi-rigid plastic material.
• the internal incision 11 has variable depth along its length; when included, this characteristic improves the opening of the sealed package 1 when the sealed package 1 is folded in a "V" shape.
• the variable depth of the internal incision 11 along its length enables achieving progressive fracturing of the sheet 2 of semi-rigid plastic material when the sealed package 1 is folded in a "V" shape .
• external incision 9 also has variable depth along its length.
• both incisions 9 and 11 may have variable depth along their length, only one of the two incisions 9 and 11 may have variable depth along its length, or both incisions 9 and 11 may have a constant depth along their length depending on the particular embodiment.
• the sealed package 1 has a generally rectangular shape. In other embodiments, it should be appreciated that the sealed package 1 may have any other shape suitable for performing the functions described herein and otherwise consistent with the description.
• the sealed package 1 may have a generally round shape, elliptical shape, "bottle” shape, rhomboidal shape, regular or irregular polygonal shape (e.g. pentagonal, hexagonal, triangular, square, etc.), "bone” shape, or another suitable shape.
• the main body 17 of the sheet 2 and the sheet 3 may have a generally symmetric or asymmetric shape.
• the outer surface 10 of the sheet 2 of semi rigid plastic material and/or the outer surface of the sheet 3 of flexible plastic material can be printed, both to carry information regarding the product 5 and for greater aesthetic decoration .
• the user holds the sealed package 1 relatively vertical with the protuberance 7 facing downwards and vertically aligned with the area where it is wished to supply the (preferably liquid) product 5 contained in the pocket 4 (e.g. the inlet mouth of a tank 19 of an electronic device such as a vaporizer) .
• the pocket 4 e.g. the inlet mouth of a tank 19 of an electronic device such as a vaporizer
• the user must fold the sealed package 1 in a "V" shape to cause the sheet 2 of semi-rigid plastic material to break at the pre-weakened area 6 as described above (in particular at the internal incision 11); the (preferably liquid) product 5 flows out from the pocket 4 through the internal incision 11 and downwards due to the effect of gravity, across the protuberance 7 until it leaves the sealed package 1 (typically by dripping) from the central area of the protuberance 7.
• the protuberance 7 serves as a high precision delivery mechanism.
• the final portion of the protuberance 7 can also be inserted inside the inlet mouth of the tank 19.
• the fluid product 5 may be a vaporizable e-liquid (e.g. stimulant-containing) substance.
• the protuberance 7 serves as a tip or docking station to be inserted in the inlet mouth of a tank of a vaporizer for the safe and high precision dispensing of the product 5 into the vaporizer tank.
• the vaporizable stimulant-containing substance or other product 5 may be used in conjunction with any of the embodiments and features described herein.
• the above-described sealed package 1 enables delivering a liquid product 5 contained inside it (namely, in the pocket 4) with extreme precision in a small space.
• the above-described sealed package 1 is extremely simple and intuitive to use due to its '''asymmetry" , as the user (even if not informed beforehand) naturally tends to hold the sealed package 1 relatively vertically with the protuberance 7 facing downwards and vertically aligned with the area in which it wishes to supply the (preferably liquid) product 5 contained in the pocket 4 (e.g. the inlet mouth of a tank of an electronic device such as a vaporizer) .
• the presence of the protuberance 7 gives the sealed package 1 a shape that intuitively guides the user, even if inexperienced, to immediately use the sealed package 1 in the correct manner without any realistic possibility of error .
• the above-described sealed package 1 is simple and inexpensive to make.
