Abstract

A bottle (10) substantially spherical in shape and with a concave recess (20, 21) in three sides so that other bottles in the vicinity of the bottle can be located so close to the said bottle that at least portions (15) of the other bottles are, directly or via a spacing piece, in the said recesses. The neck portion (11) of the bottle is directed vertically upwards or obliquely to the side and upwards. A recess (21) in the bottom of the bottle is similar to the recesses (20a, 21b) in the side walls or, in the middle of the recess in the bottom, there is an additional recess (21b) for the neck portion (11) and/or cap of a bottle.

Description

BOTTLE AND BOTTLE PACKAGE

OBJECT OF THE INVENTION

The object of the invention is a spherical bottle having, at least on one of its sides, a recess or a notch so that another bottle in the vicinity of the bottle can be located so close that at least portions of the other bottle are, directly or via a spacing piece, in the said recess.

PRIOR ART When transporting and packing bottles in boxes or other transportation packages, bottles are generally not in contact with one another, leaving a great deal of empty space between the bottles. This is due both to the shape of bottles and often also to divider walls or similar structures between the bottles. Thus the package becomes unnecessarily large in relation to the volume of the bottles, which means that, uneconomically, a lot of empty space has to be transported.

Attempts have been made to solve this problem by shaping the bottles so as to pack them as tightly against one another as possible, using quadrangular and triangular shapes for the bottles. However, such forms are not very strong and durable, making it necessary to provide the bottles with uneconomically thick walls. A known solution is presented in the publication DE-299 07 258 U1 , which presents a bottle with a recess for an adjacent bottle. Thus adjacent bottles can be packed closer to one another. The publication DE-296 00 051 U1 presents a bottle with a recess for the mouth and the cap of the bottle under it. These solutions are, however, not very advantageous.

PURPOSE OF THE INVENTION

The purpose of this invention is to create a bottle which overcomes the above-mentioned drawbacks. A further purpose of this invention is to create a strong bottle shape enabling the packing of several bottles on top of one another.

CHARACTERISTICS OF THE INVENTION

A bottle according to the invention is characterised in that there are recesses in three sides of the bottle so that other bottles both beside the said bottle and on top of or below it may be located so close to the said bottle that at least portions of the other bottles are, directly or via a spacing piece, in the said recesses. The packing density of such bottles can be very high. In other words, the total volume of the contents of the bottles is very high in relation to the space required for the multi-bottle package. Thanks to the invention, the bottle package can be made very small in terms of its external dimensions. This makes the raw material requirements for both the bottles and the package substantially smaller than in known solutions.

EMBODIMENTS OF THE INVENTION

A preferred embodiment of the bottle according to the invention is characterised in that the bottle is substantially spherical, and - the recesses in three sides of the bottle are concave so that the spherical surface of a bottle in the vicinity of the said bottle can be fitted into the said recess.

The spherical shapes of the bottle according to the invention make the bottle very strong. Its wall thickness can be decreased without decreasing the strength, which reduces the required amount of raw materials. A spherical bottle is also very resistant to pressure. Furthermore, the concave recesses in combination with the spherical surface provide a shape that reflects light in a unique way, giving the bottle and its contents an advantageous appearance. A bottle according to the invention is therefore preferable also for retail consumer packages.

Another preferred embodiment of the bottle according to the invention is characterised in that the neck portion of the bottle is directed obliquely to the side and upwards, and the said recesses in the side wall of the bottle are in the vicinity of the neck portion of the bottle, on both sides of the neck portion.

A third preferred embodiment of the bottle according to the invention is characterised in that the bottle is substantially spherical, - in two sides of the bottle, there is a concave recess for adjacent spherical bottles, and a recess in the bottom of the bottle is so shaped that the neck portion and/or cap of a bottle underneath it may be fitted into the recess.

The object of the invention also includes a bottle package, wherein the spherical bottles can be placed. The bottle package according to the invention is characterised in that the bottle package includes a stacking rack or a packing box, which is in an inclined position relative to the horizontal plane during the packing of bottles. According to one preferred embodiment, the plane of the stacking rack is most preferably at an angle of 45° relative to the horizontal plane, and the bottles are put into place by hanging them on its neck.

DESCRIPTION OF THE FIGURES Figure 1 is a top view of a bottle 10 according to the invention. In the usual way, the top portion of the bottle 10 comprises a neck portion 11 and a thread 12 for a threaded cap, which is not shown in the figure. The bottle 10 in Fig. 1 is substantially spherical in shape; however, there are two concave recesses 20a and 20b in a spherical side surface 15 of the bottle 10. The curvature of the recesses 20a and 20b matches the curvature of the surface 15 in the bottle 10 so that spherical sides of similar bottles placed in the vicinity can be fitted into the recesses 20a and 20b. Furthermore, the bottle 10 also has a recess in its bottom, the recess being shown in greater detail in Fig. 5.

Figure 2 shows a side view of the bottle 10 in Fig. 1. Fig. 2 also shows one recess 20a of the spherical side wall 15 of the bottle 10 and the recess 21 in the bottom. The recess 21 is also concave and substantially matches the shape of the spherical surface 15. In this embodiment, however, the recess 21 also has a recess for the neck portion 11 of the bottle underneath, as shown in Fig. 5.

Figure 3 shows the bottle 10 in Fig. 1 as seen from another side. As the figure illustrates, the spherical side wall 15 of the bottle 10 has concave recesses 20a and 20b in two sides and a recess 21 in the bottom.

In Figure 4, the bottle 10 is shown with the recess 20a in the spherical side wall 15 of the bottle 10 towards the viewer. The sectional view in Figure 5 shows that the concave recess 20a in the side wall 15 of the bottle 10 matches in shape the spherical side surface 15 of the bottle 10. An annular edge portion 21a of the recess 21 in bottom of the bottle 10 also matches in shape the spherical surface of the bottle 10, so that the edge portion 21a rests on the spherical surface around the neck portion 11 of a similar bottle located underneath. The recess 21 also includes a deeper mid portion 21 b, which provides sufficient space for the neck portion 11 and the threaded cap of a similar bottle underneath.

Figure 6 shows several bottles 10a-10d in accordance with Figures 1-5 placed adjacent to and on top of one another. In this example, one group contains eight bottles placed tightly against one another, but a bottle package or box can naturally contain any number of bottles. Figure 7 shows the group of bottles in Fig. 6 from another side.

Figure 8 is a sectional view of a group of bottles 10. As the sectional view shows, a side wall of each bottle 10 has a concave recess 20a, wherein the spherical side wall surface 15 of the adjacent bottle 10 fits and whereon it can rest. The bottom of the bottle 10 also has a recess 21 , the annular edge portion 21a of which recess rests on the spherical surface around the neck portion 11 of the bottle 10 located underneath. The neck portion 11 of the bottle 10 underneath is fitted into a deeper portion 21 b in the middle of the recess 21. Thus the bottles 10 rest with their side walls on the adjacent bottles and with their bottom portions, on the bottle underneath. This kind of packaging method for bottles is very stable because the bottles have support portions that fit well into one another. At the same time, the bottles in a way lock into one another, which is advantageous for transportation of the bottles.

Figure 9 is a top view of the group of bottles in Figures 6-8. As the figure shows, the bottles 10 are located tightly against one another, also as seen from this direction. Almost no empty space at all is left between the bottles 10, which gives a very high total volume relative to the volume of the entire package. Thus the packing density of bottles according to the invention is very high, and bottles according to the invention provide a highly efficient and advantageous solution for packaging and transporting liquids.

Figures 10 and 11 are axonometric views of the bottle group in Figures 6-9 from various sides. These figures also clearly show how well the bottles 10 can be fitted in a tight group against one another. Figure 12 is a top view of a bottle 10 according to another embodiment of the invention. Similarly to the embodiments shown in Figures 1-11 , this embodiment has concave recesses 20a and 20b in a spherical side wall 15 of the bottle 10. However, the bottle 10 in Fig. 12 differs from those presented above in that the neck portion 11 of the bottle 10 and the thread portion 12 belonging therein are directed obliquely to the side and upwards. Thus the neck portion 11 is not in the middle of the bottle 10, directed vertically upwards, as in a conventional bottle.

The solution presented in Fig. 12 provides an adequate space in the small empty space between the bottles in the package or bottle group for the neck portion 11 of the bottle 10 and for the threaded cap thereon, which is not shown in the figure. As a result of this, no notch has to be made separately in the bottom of the bottle 10 for the neck portion 11 and cap of the bottom 10 underneath. The topmost bottle 10 can rest directly on the spherical surface 15 of the bottle 10 beneath because, in this embodiment, the bottom of the bottle 10 comprises a similar concave recess matching the spherical surface 15 as in the bottle's side wall. The shape of bottle according this embodiment is shown in greater detail in the following figures.

Figures 13-15 are side views of the bottle 10 in Fig. 12 as seen from three different sides. As the figures show, the spherical side wall 15 of the bottle 10 has two concave recesses 20a and 20b, and the neck portion 11 is located at a vertex between the recesses, directed obliquely to the side and upwards. The bottom of the bottle 10 is a part of the same spherical shape and surface 15 as the other walls of the bottle 10, but in this second embodiment the bottom of the bottle 10 has a concave recess 20c similar to the recesses 20a and 20b in the side walls. Thus the bottle 10 comprises three recesses 20a, 20b and 20c matching the concave, spherical surface, the recesses being located in a similar position relative to one another as three faces of a cube having a common vertex.

Figure 16 is a sectional view of the bottle 10 showing that the spherical surface 15 of the bottle 10 has two similar concave recesses 20a and 20b in the side wall and one recess 20c in the bottom.

Figure 17 shows several bottles 10a-10d in accordance with Figures 12-16 placed adjacent to and on top of one another. In this example also, one group contains eight bottles placed tightly against one another, but a bottle package or box can naturally contain any number of bottles. Figure 18 shows the group of bottles in Fig. 17 from another side. Figure 19 is a sectional view of a group of bottles 10. As the section shows, each bottle 10 has a concave recess 20a in its side wall, wherein the spherical side wall surface 15 of the adjacent bottle 10 fits and whereon it can rest. The side surface 15 of the bottle 10, beside the recess 20a, has another, similar recess 20b. The bottom of the bottle 10 also has a similar recess 20c, so that in this embodiment the spherical surface 15 of the bottle 10 has three concave recesses 20a, 20b and 20c. Figure 20 gives an additional top view of the group of bottles in Figures 17-19.

Figures 21 and 22 are axonometric views of the group of bottles in Figures 17-20 from various sides, with bottles 10 according to the second embodiment of the invention.

Figure 23 shows a third embodiment of the bottle 10 according to the invention, wherein an alignment recess 22 is arranged in the top portion of the spherical surface 15 of the bottle 10. The recess 22 is oval in shape.

Figure 24 is a sectional side view of the bottle 10 in Fig. 23. Opposite to the alignment recess 22 in the top portion of the spherical surface 15, below the sphere 10, there is an alignment protrusion 23, which is also oval in shape, as seen from below the sphere 10, so that the shape of the protrusion matches the alignment recess 22. When the bottles 10 are placed on top of one another, the alignment protrusion 23 in the bottom of the topmost bottle goes into the alignment recess 22 on top of the lowermost bottle. Thus bottles placed on top of one another are locked to one another so that they cannot slide or rotate relative to one another. It is specifically the elongated oval shape of the alignment protrusion 23 and the alignment recess 22 that prevents the rotation of bottles relative to one another. This shape can also be different, however, as long as it creates a similar locking effect.

Figures 25 and 26 are axonometrically presented oblique side views of the bottles 10 with an alignment protrusion 23 and an alignment recess 22 as shown in Figures 23 and 24.

Figure 27 is a sectional side view of the bottles 10 according to Fig. 24 shown placed against one another. This leaves very small spaces between the bottles 10, and the bottles 10 are locked in place by means of the alignment protrusions 23 and the alignment recesses 22. Figure 28 shows bottles 10 placed on a stacking rack 30 or in a packing box, tightly against one another. In this figure, two walls of the stacking rack 30 are shown, whereby the position and location of the bottles 10 placed in the box stand out clearly. Due to the shape of the bottles 10, it is most preferable to stack the bottles in the stacking rack 30 or in the packing box so that the tray or the packing box 30 is in an oblique position, as if having one of its corners downwards. In this way it is easy to place the bottles 10 in place, and they will settle tightly against one another. Figure 29 shows the packing arrangement in Fig. 28 as seen from another direction.

Figure 30 matches Fig. 27 and shows the bottles 10 placed against one another so that there are packing trays 31 between bottle layers. The packing trays 31 are shaped so that the bottles 10 will settle tightly also in this arrangement. The packing tray 31 also has matching shapes for the alignment protrusions 23 and the neck portions 11 of the bottles 10. Figure 31 is an oblique side view of the bottles 10 and the packing trays 31 between them.

Figure 32 is a sectional side view of a bottle 10 according to Fig. 24, with a cap 24 and shown filled with liquid 40. The surface 41 of the liquid 40 forms a circular pattern inside the spherical bottle 10. In this way the appearance of the bottle 10 filled with the liquid 40 is particularly attractive because, due to its shape, the bottle has circular details on several sides. The spherical surface of the bottle 10 functions as a lens, creating a magnified impression of an object behind the bottle. Similarly, the concave recesses, spherical and circular in shape, function as a lens that creates a diminishing impression of an object behind the bottle. The visual appearance is completed by the spherical shape created by the liquid surface.

ADDITIONAL NOTES

It is obvious to a person skilled in the art that the different embodiments of the invention may vary within the scope of the claims presented below. Thus a bottle according to the invention may in some cases also deviate from the spherical shape. It is essential, however, that the bottles overlap one another by means of the recesses described above. Advantageously, the bottles described above are tightly against one another. In some cases, a spacing piece or padding, such as plastic foam, may be added between the bottles if required, for example when it is known that the bottles or their package will be subjected to exceptionally hard impacts or vibrations. The spherical shape is particularly advantageous due to its resistance to high pressure. The outside surface of the bottle is substantially a sphere, and the recesses on the surface are also spherical surfaces directed inwards, the curvature radii of which are most preferably equal to the curvature radius of the spherical surface of the bottle. Shaped this way, the bottles can be packed more tightly than bottles of any other shape. In other words, the packing density, i.e. the relation of the total volume of the bottles to the volume of the entire package, is maximal.

The applicant has found that a conventional, 1200 mm x 1000 mm sized Europallet can accommodate regular soft drink bottles in two layers, which gives a total volume of 200- 230 litres. A unit of the same height can accommodate five layers of spherical bottles according to the invention giving a total volume of 300 litres.

Most preferably, the concave recesses in the spherical bottles are located in three sides, i.e. one in the bottom and two in the side walls. The section planes of the segments of the recesses are thus most preferably perpendicular to one another, i.e. their principal directions are perpendicular relative to the axes x, y and z in a three-dimensional rectangular coordinate system. In this way the bottles also lock well relative to one another in the package. During packaging, it is easier to place the bottles on top of one another when the bottles have the alignment recesses and alignment protrusions described above. No intermediate trays are necessarily needed between the bottles because the bottles settle tightly against one another. Shaped packing trays can be used, however, because they align the bottles well relative to one another.

A bottle according to the invention can be provided with a barcode for an automatic bottle collection machine. In this case, the barcode is most preferably located on the spherical side surface of the bottle because the collection machine will spin the bottle to recognise the bottle by means of the barcode.

For packaging and stacking, it is preferable to use a stacking rack with the surfaces at a 45° angle relative to the horizontal plane. In this way the bottles can be lowered into place by hanging them by the neck. LIST OF REFERENCE NUMBERS
