Description

[0001] Refillable drinking bottle

[0002] Technical field of the invention

[0003] The invention relates to a refillable drinking bottle that allows for easy filling even when there is limited space under the faucet. Because the drinking bottle is flat, it can also be easily and conveniently stored.

[0004] State of the art

[0005] Drinking bottles are usually filled through the same opening from which the drink is drunk. Since most drinking bottles are bottle-shaped, easy filling at a sink is only guaranteed if the sink is deep enough to position the bottle exactly vertically under the tap, i.e. in a vertical orientation. If the sink is not deep enough, the bottle must be held at an angle, which, depending on the angle of the bottle, can lead to considerable water loss during filling. This is unsatisfactory and unacceptable from a sustainability perspective. Furthermore, some bottles are not refillable at sinks due to their size, as they do not fit under the tap.

[0006] Drinking bottles with a second opening are already known from CN-A 101 756 483 and ES-A 2 933429. However, even when positioned horizontally, the bottle still takes up a lot of space, making it impossible to fill taps where there is little space available. The object of the present invention was therefore to design a bottle that allows easy filling, even when there is very little space available under the tap, or between the tap and the sink, or the tap is located in a niche, which is usually not possible for normal water bottles.

[0007] Summary of the invention

[0008] This object is achieved by the refillable drinking bottle according to the invention, which comprises a cuboid-shaped container with a first closable opening, a second closable opening, a first side surface, a second side surface and a third side surface and preferably rounded corners, wherein the first closable opening is designed as a drinking opening and is attached to the first side surface, wherein the width bl of the first side surface is 0.1 times to five times the diameter dl of the first closable opening, wherein the second closable opening is designed as a filling opening and is attached to the second side surface of the cuboid-shaped container, wherein the area of ​​the second side surface is both larger than the area of ​​the first side surface and larger than the area of ​​the third side surface.

[0009] In particular, the width bl of the first side surface is 0.2 to five times the diameter dl of the first closable opening, preferably the width bl of the first side surface is one to five times the diameter dl of the first closable opening, particularly preferably the width bl of the first side surface is one to three times the diameter dl of the first closable opening, very particularly preferably the width bl of the first side surface is one to one and a half times the diameter dl of the first closable opening.

[0010] Preferably, the first and third side surfaces have the same width, i.e., bl = b3 (see Fig. 1), also called the "depth" of the drinking bottle. For drinking bottles with particularly small depths bl and b3, drinking water can also be drawn off through tubes inserted into the first opening. Alternatively, the tube can already be integrated into the bottle.

[0011] The drinking bottle according to the invention is characterized in that it is flat, and the opening for filling the bottle is located on the largest side surface of the cuboid-shaped container, so that only little space is required below a tap to fill the bottle, since the drinking bottle according to the invention can be filled in a horizontal orientation (the vertical orientation is shown in each of the figures). The closer the second opening is to the first opening or to the lower edge of the second side surface, or the more the second opening is located in the two lower corners of the second side surface, or the shallower the first and third sides are (small bl and small b3), the less space is required to fill the bottle.The bottle can be placed under the tap both horizontally in alignment with the transverse axis Q and horizontally in alignment with the longitudinal axis L, even if there is little space between the tap and the sink to allow easy refilling.

[0012] In a first preferred embodiment of the drinking bottle according to the invention, the area of ​​the second side surface of the cuboid-shaped container is at least four times as large as the area of ​​its first and third side surfaces.

[0013] In a second preferred embodiment of the drinking bottle according to the invention, the area of ​​the second side surface of the cuboid-shaped container is at least seven times as large as the area of ​​its first and third side surfaces.

[0014] In a further preferred embodiment of the drinking bottle according to the invention, the area of ​​the second side surface of the cuboid-shaped container is at least ten times as large as the area of ​​the first and the third side surface.

[0015] In an exemplary embodiment of the drinking bottle according to the invention, it has a height with lid of 23.8 cm, a width of 13.5 cm, and a depth of 2.7 cm, with the first closable opening having an inner diameter of 1.9 cm and the second closable opening having an inner diameter of 3 cm. The drinking bottle designed in this way has a capacity of approximately 0.75 l. However, the present invention is not limited to this exemplary embodiment. For example, flat drinking bottles with the inventive features according to claim 1 and a capacity in the range of 0.2 to 2.5 l are also encompassed by the invention. The dimensions given in this patent application are therefore purely illustrative and do not represent a restriction of the drinking bottle according to the invention to these dimensions.Therefore, drinking bottles with smaller or larger capacities than those mentioned are also encompassed by the invention.

[0016] In further exemplary embodiments of the drinking bottle according to the invention, it has a height with lid in the range of 10 to 35 cm or 15 to 30 cm, a width in the range of 8 to 20 cm or 8 to 15 cm, and a depth bl / b3 in the range of 0.5 to 8 cm, with the first closable opening having an inner diameter in the range of 0.5 to 8 cm and the second closable opening having an inner diameter of 1 to 20 cm. Each size specification can be arbitrarily combined with any other size specification. This also applies to the dimensions mentioned below.

[0017] Drinking bottles with a depth bl and b3 in the range from 0.5 to 6 cm, in particular in a range from 1.5 to 5 cm, are particularly preferred.

[0018] The first closable opening has in particular an inner diameter in the range of 0.6 to 8 cm, preferably in the range of 0.8 to 5 cm, particularly preferably in the range of 1.0 to 4 cm, very particularly preferably in the range of 1.5 to 2.5 cm.

[0019] The second closable opening has in particular an inner diameter in the range of 1 to 10 cm, preferably in the range of 1 to 7 cm, particularly preferably in the range of 1.5 to 5 cm, most particularly preferably in the range of 2.0 to 4.0 cm.

[0020] In a third preferred embodiment of the drinking bottle according to the invention, the first closable opening is arranged centrally on the first side surface of the cuboid-shaped container.

[0021] The terms “side area”, “upper area”, “quadrant” and “corner area” used below each refer to an area that represents a section of the second side area.

[0022] In a fourth preferred embodiment of the drinking bottle according to the invention, the second closable opening is provided in a side region of the second side surface of the cuboid-shaped container. This side region extends over the length of the second side surface and is delimited by one of the longitudinal edges of the second side surface. The width of the side region is preferably approximately one-quarter to one-half of the total width of the second side surface; more preferably, the width of the side region is one-quarter to one-third of the total width of the second side surface. In Fig. 1, this side region 4 is delimited by the dashed line 14 and the first longitudinal edge 34, as well as by the upper edge 36 and the lower edge 37 of the second side surface. This side region (shown in Fig.1 ) therefore extends here very particularly preferably along the longitudinal axis L of the second side surface with a width which approximately corresponds to the diameter of the second opening. In Fig. 1 the side region is shown on the right-hand side as seen from the observer; it can of course also be located on the left-hand side. In a fifth preferred embodiment of the drinking bottle according to the invention the second closable opening is arranged in the upper region of the second side surface of the cuboid-shaped container. This upper region of the second side surface (shown in Fig. 2) is located in the upper half, ie the half facing the first opening, of the second side surface, and preferably takes up approximately a quarter to a half of the second side surface.

[0023] Alternatively, the second closable opening of the drinking bottle according to the invention can also be located in the lower region of the second side surface of the cuboid-shaped container. This lower region of the second side surface (shown in Fig. 2) is located in the lower half, i.e., the half of the second side surface facing the lower edge, and preferably occupies approximately one-quarter to one-half of the second side surface, viewed from the lower edge of the second side surface.

[0024] In a sixth preferred embodiment of the drinking bottle according to the invention, the second closable opening is arranged in a quadrant of the second side surface of the cuboid-shaped container. This quadrant is located in the upper half of the second side surface adjacent to the first opening. In Fig. 1, the second opening is located in the top right quadrant; however, it could also be located in the top left quadrant. The second opening could equally well be located in the bottom right or bottom left quadrant. This is particularly advantageous for cleaning the drinking bottle according to the invention by rinsing it with a cleaning solution.

[0025] In a seventh preferred embodiment of the drinking bottle according to the invention, the second closable opening is provided in a corner region of the second side surface of the cuboid-shaped container. The second closable opening is preferably located in a corner region adjacent to the first side surface on which the first closable opening is located. The length of this corner region is preferably approximately one-third to one-quarter of the total length of the second side surface and / or the width of this corner region is preferably approximately one-third to one-quarter of the total width of the second side surface. In a particularly preferred embodiment, the second opening is circular, the corner region is approximately square, and the length and width of the corner region, which is delimited by the upper edge and one of the two lateral longitudinal edges of the second side surface, correspond to the diameter of the second opening + 50%.Preferably, the length and width of the corner region, which is bounded by the upper edge and one of the two lateral longitudinal edges of the second side surface, correspond to the diameter of the second opening + 30%, particularly preferably to the diameter of the second opening + 20%. In Fig. 1, the corner region is located on the right side; however, it could also be located on the left side, or correspondingly in the lower region of the second side surface.

[0026] The position of the second closable opening in a corner region of the second side surface reduces the space required for filling the drinking bottle to a minimum. This enables the drinking bottle to be filled even when the distance between the tap and the wall to which it is attached is relatively small. Thus, advantageously, only a distance of length 12 between the tap or its water outlet opening and the wall behind it (distance from the upper edge of the first lid to the middle of the second opening; see Fig. 1 ) or a distance of length II (length of the first side surface; see Fig. 1 ) from the walls on either side of the tap is necessary in order to be able to fill the drinking bottle according to the invention.

[0027] If the second opening is located in a corner area in the lower half of the second side panel or adjacent to the lower edge of the second side panel, the required distance is further reduced. The required minimum distance is then only the distance from the lower edge of the second side panel to the center of the second opening.

[0028] In a further preferred embodiment, the second closable opening is located in a corner region of the second side surface of the cuboid-shaped container, which is bounded by the lower edge of the second side surface and one of the longitudinal edges of the second side surface. The above-mentioned preferences for the size of this corner region are also preferred in this embodiment.

[0029] In an eighth preferred embodiment of the drinking bottle according to the invention, this drinking bottle has a first lid designed to close the first closable opening. The first lid can be designed in any manner known to those skilled in the art. For example, the first lid can be designed as a flap, a slider, or a twist-off cap. Furthermore, the closure can be effected, for example, by magnetic forces, either by the first opening being made of metal and the first lid being a magnet, or vice versa.

[0030] In a ninth preferred embodiment of the drinking bottle according to the invention, this drinking bottle has a second lid designed to close the second closable opening. The second lid can be designed in any manner known to those skilled in the art. For example, the second lid can be designed as a flap, a slider, or a twist-off cap. Furthermore, the closure can be effected, for example, by magnetic forces, either by the second opening being made of metal and the second lid being a magnet, or vice versa.

[0031] The two openings and the two lids can be designed either identically or differently from one another. In a tenth preferred embodiment of the drinking bottle according to the invention, the second closable opening has a diameter approximately one and a half times (1.5 times) as large, preferably twice as large, as the first closable opening. A large second opening has the advantage that the drinking bottle according to the invention can be filled quickly.

[0032] In an eleventh preferred embodiment of the drinking bottle according to the invention, the second closable opening and / or the second lid are designed such that the second lid does not protrude beyond the second side surface. This makes the drinking bottle even easier to store, since the second side surface is not raised by the second opening and its lid, but is completely flat. The second opening is virtually recessed into the second side surface. Here, the lid could, for example, be provided with a foldable hook or handle that can be positioned by folding it 90° so that the lid can be unscrewed.

[0033] In a twelfth preferred embodiment of the drinking bottle according to the invention, the second closable opening and / or the second lid are circular. In this embodiment, the second opening preferably has an internal thread and the second lid preferably has an opposing external thread, or vice versa. However, designs without a thread are also possible. The thread can extend over the entire vertical extent of the second closable opening and / or the entire vertical extent of the second lid or only over part thereof. This means that the thread can, for example, extend only over the lower, middle or upper part of the respective vertical extent. So that the lid is easier to grip and rotate, it can also be angular, for example square, rectangular, pentagonal or hexagonal.The edge of the lid could also be provided with grooves or bulges to facilitate gripping. Other possibilities known to those skilled in the art for designing the lid to make it easier to grasp are also encompassed by the invention.

[0034] In a thirteenth preferred embodiment of the drinking bottle according to the invention, the first closable opening and / or the first lid are circular. In this embodiment, the first opening preferably has an internal thread and the first lid preferably has an opposing external thread, or vice versa. However, designs without a thread are also possible. The thread can extend over the entire vertical extent of the first closable opening and / or the entire vertical extent of the first lid or only over part thereof. This means that the thread can, for example, extend only over the lower, middle or upper part of the respective vertical extent. So that the lid is easier to grip and rotate, it can also be angular, for example square, rectangular, pentagonal or hexagonal.The edge of the lid could also be provided with grooves or bulges to facilitate gripping. Other possibilities known to those skilled in the art for designing the lid to make it easier to grasp are also encompassed by the invention.

[0035] In a fourteenth preferred embodiment, the two openings and the two lids each have a complementary rotating thread, also called a thread. In one embodiment of the drinking bottle according to the invention, the first opening and the second opening have an external thread, and the associated lids each have a complementary internal thread. In another embodiment, however, the first opening and the second opening could also have an internal thread, and the associated lids could have a correspondingly complementary external thread. The thread preferably extends over the entire vertical extent of the first or second opening.

[0036] The drinking bottle can be made from any food-safe material. For example, the drinking bottle can be made from a plastic and / or metal-based material; production from renewable raw materials such as bamboo is also possible. The drinking bottle is preferably made from a material that does not deform when the drinking bottle is emptied or filled. In a preferred embodiment, at least the cuboid-shaped container and / or the openings are made from a metal-based material, preferably metal or a metal alloy, particularly preferably stainless steel or aluminum, and most preferably stainless steel. However, the drinking bottle, in particular the cuboid-shaped container and / or the openings, could also be made from hard plastic or another food-safe material that cannot deform when the drinking bottle is filled.A food-grade material that deforms when the drinking bottle is filled can also be used as an alternative.

[0037] The lids can be made of either a flexible plastic (polyethylene, polypropylene) or of metal or a metal alloy, particularly stainless steel or aluminum. The lids can also be provided with a seal, for example, made of plastic such as polyethylene or polyvinylidene chloride.

[0038] The drinking bottle according to the invention can be cleaned, for example, with appropriate cleaning tablets or by allowing a cleaning solution to flow through it. The features of the above-mentioned preferred embodiments and their preferences can be combined with one another as desired in a drinking bottle and are encompassed by the present invention.

[0039] The following description of the preferred embodiment serves as a non-limiting illustration of the present invention.

[0040] Short description of the drawings

[0041] Figure 1 shows a perspective view of a preferred embodiment of the drinking bottle according to the invention.

[0042] Fig. 2 shows a side view of the embodiment of Figure 1. Fig. 3 shows the embodiment of Figure 1 in an exploded view with the openings open.

[0043] Fig. 4 shows a perspective view of another preferred embodiment of the drinking bottle according to the invention.

[0044] Preferred embodiment of the invention

[0045] Figure 1 shows a preferred embodiment of the drinking bottle 10 according to the invention, which comprises a cuboid-shaped container 3 with a first closable opening 1, a second closable opening 2, a first side surface 31, a second side surface 32 and a third side surface 33, as well as preferably rounded corners 13, 13', 13", 13"'.

[0046] It can be clearly seen that the area of ​​the second side surface 32 is at least four times larger than the area of ​​the first side surface 31, as well as the area of ​​the third side surface 33.

[0047] The first closable opening 1 is designed as a drinking opening and is located centrally on the first side surface 31, i.e., on the short, narrow side of the cuboid-shaped container. It is closed with a first lid 1. Preferably, the width bl of this first side surface 31 is not significantly larger than the diameter dl of the first closable opening 1.

[0048] The second closable opening 2, which serves to fill the drinking bottle, is located on the second side surface 32 of the cuboid container, i.e., on the wide side. The second opening 2 is located in the side area 4 of the cuboid container, in particular in the corner area 5 of the cuboid container, and is closed with a second lid 12.

[0049] The side region 4 is delimited by the dashed line 14 and the first longitudinal edge 34, as well as by the upper edge 36 and the lower edge 37 of the second side surface. This side region 4 therefore particularly preferably extends along the longitudinal axis L of the second side surface with a width that approximately corresponds to the diameter of the second opening.

[0050] The second closable opening 2 is also advantageously arranged in the upper region 6 of the second side surface 32. This upper region 6 of the second side surface 32 is located in the upper half, i.e., the half of the second side surface 32 facing the first opening 1, and preferably occupies approximately one-quarter to one-half of the second side surface 32. Here, the dashed line 16 is shown as an example to delimit the upper region.

[0051] In another advantageous embodiment, the second opening 2 could also be located in the lower region 7 of the second side surface. This lower region 7 of the second side surface 32 is located in the lower half, i.e., the half of the second side surface 32 facing the lower edge 37, and preferably occupies approximately one-quarter to one-half of the second side surface 32.

[0052] The second closable opening 2 is preferably arranged in a quadrant 15 of the second side surface 32 of the cuboid-shaped container. The quadrant 15 is located in the upper half of the second side surface 32 adjacent to the first opening 1. In the embodiment shown here, the second opening 2 is arranged on the right side of the second side surface 32, as viewed from the viewer, or in the right quadrant 15. However, the opening could just as easily be located on the left, i.e., in the left quadrant 25 or the corresponding corner area.

[0053] If the drinking bottle 10 according to the invention is filled horizontally in alignment with the transverse axis Q, only a distance of the walls located on both sides of the tap of the length of the second side surface 32 is necessary in order to be able to fill the drinking bottle according to the invention.

[0054] If the drinking bottle 10 according to the invention is filled horizontally in alignment with the longitudinal axis L, even less space is required: In this case, a distance of the tap or its water outlet opening from the wall behind it of length 12 (distance from the upper edge 51 of the first lid to the middle 52 of the second opening) is sufficient to be able to fill the drinking bottle according to the invention.

[0055] In further embodiments of the drinking bottle 10 according to the invention, the second opening 2 could also be located in the lower left quadrant 55 or in the lower right quadrant 45, or in the corresponding corner regions, which are each delimited by the lower edge 37 and one of the two longitudinal edges 34 or 35.

[0056] This means that the second opening 2 could also be located adjacent to the lower edge 37 or even in the lower half of the second side surface. The closer the second opening 2 is to the lower edge 37, the smaller the distance required between the faucet attachment and the water outlet opening, or the space required to fill the drinking bottle 10 according to the invention horizontally in alignment with the longitudinal axis L.

[0057] Figure 2 shows the embodiment of the drinking bottle 10 according to the invention shown in Figure 1 from above onto the first side surface 31. The width bl of the first side surface 31 is not significantly larger than the diameter dl of the first closable opening 1, which is closed here by the first lid 11. The second closable opening 2, which is closed here by the second lid 12, is located at a 90° angle to the first closable opening 1 on the second side surface 32.

[0058] Figure 3 shows the embodiment of the drinking bottle 10 according to the invention shown in Figure 1 with open openings 1 and 2. Here, the openings 1 and 2 each have a thread 21, so that the lids 11 and 12, which have corresponding threads (41 and 42 respectively; not visible here), can be turned clockwise onto the openings to close the openings. In the embodiment of the drinking bottle 10 according to the invention shown in Fig. 3, the first opening 1 and the second opening 2 have an external thread and the associated lids 11, 12 have an internal thread. The first opening 1 and the second opening 2 could also have an internal thread and the associated lids an external thread.

[0059] In the further preferred embodiment of the drinking bottle 10 according to the invention shown in Figure 4, the opening 2 and the lid 12 are designed such that they do not protrude beyond the second side surface 32. As a result, the drinking bottle according to the invention requires even less space for storage than the embodiment shown in Figures 1-3.
