Description

PACKAGE FOR FLUID MATERIALS AND PACKING ASSEMBLY

FIELD OF THE INVENTION The invention relates to a package for fluid material, and particularly to a solution, that is designed to be used for holding consumables such as drinks or spices. The invention also relates to a packing assembly comprising plurality of these packages.

BACKGROUND OF THE INVENTION Packages for fluid material, such as beverages or granular spices, need toreliably hold the contents, be easy to manufacture, have good logistic properties such as weight, stacking, and standing properties, and preferably be as ecological as possible. In known solutions, the above-mentioned features are implemented most often with traditional plastic bottles which are light in weight and capable of reliably holding the contents. In traditional plastic bottles, in order to keep the bot- tle vertical, the lower end of the bottle needs to be shaped to form a stand. This shaping weakens the structural integrity of the bottle, resulting in a need for add- ing mass through increasing the wall thickness in these areas to compensate for the shaping. Traditional plastic bottles also often require additional labels to indi- cate the contents. Other composite package solutions are also known where the standing ability for holding the bottle upright is provided with external structural supports. Previous solutions for composite packages are disclosed in GB1261248A, FR2013654A1, GB1537179A, US20140061150A1, FR1441098A, N 25 US4342399A, and US5462180A for instance. N A problem with the above-mentioned solutions is that each of them are O lacking in at least one of the categories listed before. For example, as the wall thick- N ness in traditional plastic bottles needs to be increased, the use of plastics is re- = spectively increased which is harmful for the environment. Also, the need for a sep- + 30 arate label causes additional manufacturing steps. The other known solutions for 2 providing the standing ability for bottles also have problems related to either reli- = ability, ease of manufacture, ecology, or logistic properties such as standing and N stacking properties and weight. Also, other packages for granular goods such as coffee or spices have similar problems.

BRIEF DESCRIPTION OF THE INVENTION An object of the invention is to introduce an improved package and an improved packing assembly, which are improved in terms of ease of manufacture, ecology, and logistic properties.

N | DETAILED DESCRIPTION OF THE INVENTION Figures 1, 5, 9, and 13 each illustrate respectively a first embodiment, a second embodiment, a third embodiment, and a fourth embodiment of a package 100; 200; 300; 400 for fluid material.

The package 100; 200; 300; 400 comprising a bottle 120; 220; 320; 420 illustrated separately in figures 2, 6, 10, and 14 for re- ceiving the material.

The bottle 120; 220; 320; 420 having a central axis X, a con- — vex-shaped bottom end portion 120a; 220a; 320a; 420a, an upper end portion 120c; 220c; 320c; 420c with an opening 121; 221; 321; 421 and a central portion 120b; 220b; 320b; 420b between the bottom end portion 120a; 220a; 320a; 420a and the upper end portion 120c; 220c; 320c; 420c.

The package 100; 200; 300; 400 further comprising a tubular shell 130; 230; 330; 430 illustrated separately in fig- ures3,7,11, and 15 around the lower end portion 120a; 220a; 320a; 420a and at least part of the central portion 120b; 220b; 320b; 420b of the bottle 120; 220; 320; 420. The shell 130; 230; 330; 430 having an upper end 130b; 230b; 330b; 430b which is open and through which open end the bottle 120; 220; 320; 420 extends upwardly out of the shell 130; 230; 330; 430, and a lower end 130a; 230a; 330a; 430a extending downwardly past the bottom end 122;222;322;422 of the bottle 120; 220; 320; 420. The package further comprising a cap 140;240;340;440 for the opening 121; 221; 321; 421. This is advantageous because the shell 130; 230; 330; 430 extending downwardly past the bottom end 122;222;322;422 of the bottle 120; 220; 320; 420 acts as the stand for the package 100; 200; 300; 400, thus facilitating standing of the bottle 120; 220; 320; 420 regardless of the shape of the bottom end portion 120a; 220a; 320a; 420a of the bottle 120; 220; 320; 420. Therefore, in the shaping of the bottle 120; 220; 320; 420, preferable shapes such as convex shapes as illustrated can be used.

Also, the bottle can be made with smaller wall thickness, as it does not need to support the standing of the package.

Therefore, decreasing the use of materials in the bottle, particularly plastics, which

N pollute the environment.

AN As illustrated in figures 18 and 19, optionally in each embodiment the = central portion 120b; 220b; 320b; 420b of the bottle 120; 220; 320; 420 comprises 7 plurality of protrusions 126; 226; 326; 426, and the inner surface of the shell 130; N 30 230;330;430rests on the plurality of the protrusions 126; 226; 326; 426. This is E advantageous because it strengthens the structure of the bottle 120; 220; 320; 420, o thus giving the package 100;200;300;400 overall stronger structure.

Also, as the 3 inner surface of the shell 130; 230; 330; 430 rests on the protrusions 126; 226; N 326; 426, it decreases the contact area between the inner surface of the shell N 35 130;230;330;430 and the bottle 120; 220; 320; 420 thus lowering the friction be- tween them and therefore easing assembly and disassembly of the package

100;200;300;400 by reducing the force required to assemble or disassemble the package 100;200;300;400. Alternatively, the plurality of protrusions decreasing friction between said parts can be on the inner surface of the shell 130; 230; 330, 430 instead of the bottle 120; 220; 320; 420.

Further as illustrated in figure 19, optionally in each embodiment, the central portion 120b; 220b; 320b; 420b of the bottle 120; 220; 320; 420 comprises areas 127; 227; 327; 427 between adjacent protrusions 126; 226; 326; 426 where the inner surface of the shell 130; 230; 330; 430 does not reach into contact with the central portion 120b; 220b; 320b; 420b. Preferably, the adjacent protrusions 126; 226; 326; 426 block the inner surface of the shell 130; 230; 330; 430 from reaching into contact with central portion 120b; 220b; 320b; 420b at said areas 127; 227; 327; 427. This is advantageous as it ensures that the contact area be- tween the inner surface of the shell 130;230;330;430 and the bottle 120; 220; 320; 420 is lowered thus decreasing friction and resulting in advantages stated above.

Preferably, the plurality of protrusions 126; 226; 326; 426 extend out- wards preferably from 1 to 10 mm from the central portion 120b; 220b; 320b; 420b. Alternatively, the protrusions 126; 226; 326; 426 may extend inwards pref- erably from 1 to 10 mm from the central portion 120b; 220b; 320b; 420b. This way the protrusions 126; 226; 326; 426 would appear as recesses when viewed from — the outside but would also achieve the effect of decreasing friction between said parts.

Preferably, the plurality of protrusions 126; 226; 326; 426 are dome- like. This domelike shape is advantageous because it provides a strong and smooth structure which is easy to manufacture on the bottle 120; 220; 320; 420 but still has a decreasing sectional area towards the peak of the protrusion 126; 226; 326; N 426 resulting in advantages stated above. However, the protrusions 126; 226; 326; AN 426 may be in other forms which also decrease the contact area between the bottle = 120; 220; 320; 420 and the inner surface of the shell 130; 230; 330; 430. 7 Preferably the plurality of protrusions comprises more than 10 protru- N 30 sions. Further, the plurality of protrusions 126; 226; 326; 426 are preferably E evenly spaced on the central portion 120b; 220b; 320b; 420b. This is advantageous o as it evenly distributes the forces coming from the shell 130; 230; 330; 430 and 3 acting on the bottle 120; 220; 320; 420. However, the protrusions may also be dis- N tributed in other ways such as in random patterns or in ornamental patterns. N 35 In each of the embodiments illustrated in figures 1, 5, 9, and 13, a lower edge 131;231;331;431 of the shell 130; 230; 330; 430 defines a plane to which the central axis X is orthogonal, the lower edge 131;231;331;431 being suitable for supporting the package 100; 200; 300; 400 such that the central axis X is vertical when resting on a planar surface as illustrated in figure 17. This is particularly ad- vantageous when the package is used for holding liquids or granular goods, as this allows the package to be placed on a surface even without the cap without spilling the contents.

Additionally, this is advantageous as a fully flat surface is not required as long as the contact points between the lower edge 131;231;331;431 of the shell 130; 230; 330; 430 and the surface for resting form a plane.

In each of the embodiments illustrated in figures 1, 5, 9, and 13, the package 100; 200; 300; 400 comprises a support face 111;211;311;411 facing up- wards preferably directly or at an inclined angle, in particular for supporting on top of it another package 100; 200; 300; 400 as defined.

This support face 111;211;311;411 allows another package 100; 200; 300; 400 to be arranged on top of the package 100; 200; 300; 400, thus facilitating stacking of the packages 100;200; 300; 400 and therefore improving the logistic properties of the package 100; 200; 300; 400. In each of the embodimentsillustrated in figures 1, 5, 9, and 13, the axial distance D1 between the lower edge 131; 231; 331; 431 of the shell 130; 230; 330; 430 and the bottom end 122; 222; 322; 422 of the bottle 120; 220; 320; 420 isat least the axial distance D2 between the highest point of the package 100; 200; 300; 400 and the support face 111; 211; 311; 411. This allows preferably both the bot- tom end 122; 222; 322; 422 of the bottle 120; 220; 320; 420 and the lower edge 131; 231; 331; 431 of the shell 130; 230; 330; 430 to simultaneously rest on a pack- age 100; 200; 300; 400 below, when stacked.

This is advantageous as it allows mul- tiple contact points to bear the load.

Alternatively, solely the lower edge 131; 231; N 331;431 of the shell 130; 230; 330; 430 rests on the package 100; 200; 300; 400 O below. ~ In each of the embodiments illustrated in figures 1, 9, and 13, the sup- 7 portface 111; 311; 411 is formed by a surface of the bottle 120;320;420 extending N 30 on top of the upper end 130b; 330b; 430b of the shell 130; 330; 430. Whereas, in E the second embodiment of the package 200 illustrated in figure 5, the support face 3 211 is formed by the upper edge 232 of the shell 230. This is advantageous as no 2 external support faces are needed, therefore facilitating the manufacture of the N package.

N 35 In each of the embodiments illustrated in figures 1, 5, 9, and 13, the sup- port face 111; 211; 311; 411 is shaped to form a counterpart for the lower edge

131; 231; 331; 431 of a shell 130; 230; 330; 430 of another package 100; 200; 300; 400 as defined. Preferably the support face 111; 211; 311; 411 and the lower edge 131; 231; 331; 431 of the shell 130; 230; 330; 430 are both circular as illustrated. This is advantageous because it increases the contact area between the packages 100; 200; 300; 400 when stacked, therefore facilitating the firmness of the stack- ing.

In each of the embodiments illustrated in figures 1, 9, and 13, the pack- age 100; 300; 400 comprises a stop face 112; 312; 412 facing downwards, in par- ticular for blocking movement of the shell 130; 330; 430 upwardly past the stop face 112; 312; 412. The stop face 112; 312; 412 is placed against the upper edge 132; 332; 432 of the shell 130; 330; 430. And the shell 130; 330; 430 is arranged to support the bottle 120; 320; 420 via said stop face 112; 312; 412. This is advan- tageous as the stop face aids in accurately positioning the shell relative to the bot- tle, therefore facilitating manufacture of the package 100; 300; 400. It also pro- — videsa physical support point for the parts, reducing the stress placed on adhesion if the parts are adhered.

In the third embodiment of the package 300 illustrated in figure 9, the bottle 320 comprises a protrusion 323 around its periphery, the protrusion 323 comprising said support face 311 and/or said stop face 312. The protrusion 323 is positioned on the central portion 320b of the bottle 320 and proximal to the upper end portion 320c of the bottle 320. The protrusion 323 could also be alternatively positioned elsewhere on the bottle 320. The advantage of this is that it provides a clear and precise reference point for resting the packages 300, when the packages 300 are stacked.

In each of the embodiments illustrated in figures 1, 5, 9, and 13, the shell N 130; 230; 330; 430 surrounds a space 113; 213; 313; 413 below the bottom end N 122; 222; 322; 422 of the bottle 120; 220; 320; 420 and the space 113; 213; 313; = 413 is preferably downwardly open. This is advantageous as this space 113; 213; 7 313; 413 allows for receiving for example a part of another package N 30 100;200;300;400 into the space and/or for additional features to be placed in this E space.

o In an embodiment of the package 500 illustrated in Figure 26, the space 3 513 accommodates a centring member 550; 650 in particular for receiving and lat- N erally supporting part of another package 500 as defined. This further facilitates N 35 lateral support when plurality of packages 500 are stacked for example in a pack- ing assembly 1500 as illustrated in figure 26.

Figures 24 and 25 each illustrate an embodiment of the centring mem- ber 550; 650 that comprises an opening 551; 651 for receiving a part of a package 100; 200; 300; 400. The centring member further comprises a plurality of individ- ually conforming support tabs 552; 652 delimiting said opening 551; 651 and the support tabs 552; 652 are divided on the centring member 550; 650 with a plural- ity of radial creases 553; 653 extending outwards from the opening 551; 651. This allows for the centring member 550; 650 to be used with varying bottle shapes as the support tabs 552; 652 are able to individually conform to various angles.

In each of the embodiments illustrated in figures 1, 5, 9, and 13, the up- per end portion 120c; 220c; 320c; 420c comprises a first rounded convex corner 124; 224; 324; 424 in the periphery of the central portion 120b; 220b; 320b; 420b of the bottle 120; 220; 320; 420, and preferably a second rounded concave corner 125; 225; 325; 425 higher than the first rounded convex corner 124; 224; 324; 424. This facilitates placing the opening 121; 221; 321; 421 of the bottle 120; 220; 320; 420 to be orthogonal with the central axis X of the bottle 120; 220; 320; 420 further aiding the package 100; 200; 300; 400 in holding the contents.

230; 330; 430 of the second package 100; 200; 300; 400; 500 rests on the first package 100; 200; 300; 400; 500. And said plurality of packages 100; 200; 300; 400; 500 comprises at least a first package 100; 200; 300; 400; 500 and a second package 100; 200; 300; 400; 500 arranged on top of the first package 100; 200; 300; 400; 500, such that the shell 130; 230; 330; 430 of the second package 100; 200; 300; 400; 500 is supported by the support face 111; 211; 311; 411 of the first package 100; 200; 300; 400; 500. And said plurality of packages 100; 200; 300; 400; 500 further comprises at least a first package 100; 200; 300; 400; 500 and a second package 100; 200; 300; 400; 500 arranged on top of the first package 100; 200; 300; 400; 500, such that the upper end portion 120c; 220c; 320c; 420c of the first package 100; 200; 300; 400; 500 extends into the space 113; 213; 313; 413; 513 below the bottom end 122; 222; 322; 422 of the bottle 120; 220; 320; 420 of the second package 100; 200; 300; 400; 500. These features allow the packages 100; 200; 300; 400; 500 to be stacked directly on top of each other in the packing assembly, which negates the need for additional support surfaces positioned be- tween the packages 100; 200; 300; 400; 500, thus decreasing the amount of addi- tional materials needed in the packing assembly.

This may also reduce the need of wrapping the packing assem- bly with plastic wrap for transport. Figures 21 to 23 illustrate an embodiment of the packing assembly

1700. The packing assembly comprising a base 1080 for mounting the bottom tier 1060a of packages 300, the base 1080 further comprising elevated protrusions 1081 such that the top surface 1082 of the elevated protrusions 1081 come into — contact with the bottom end 322 of the bottle 320 of the package 300 mounted on said base 1080. This allows for forces in vertical direction to be transferred also through the bottle to the base, further facilitating load bearing ability of the pack- ing assembly 1700. The package is illustrated and described in the application in a position, where the central axis X is vertical. The features of the embodiments may be preferable, but not necessary for the package.
