Description

stack canister

The present invention relates to a stackable canister for the storage and transport of flowable material, having a bottom side, an upper side and at least one side wall connecting the underside and the top side and defining the canister circumference, and a pourable closure opening closable with a cap, the underside spaced-apart base sections and the top surface receiving surfaces which are spaced from the pouring opening.

Such canisters are used for example for the transport and storage of chemicals, pesticides and / or fertilizers. In order to make these canisters more easily stackable, they often have on their upper side laterally arranged beads which project upwards beyond a pour spout and form a receiving surface or base for a canister to be stacked above it. However, this entails the disadvantage that the liquid contained in such a canister, even if the canister is turned upside down, partially collects in the depressions formed by the beads in this position. The canister is therefore not completely emptied and there is always a residue of the contents in the canister. If the canister content is an environmentally harmful and / or hazardous product, disposal of the incompletely emptied canister is associated with considerable expense and expense. In addition, the consumer can not use a part of his purchased product, as this remains in conventional canisters in the canister. Particularly with comparatively expensive products, noticeable losses occur.

Insofar as canisters which can be completely emptied in the state of the art are described, they have a pouring opening with an upwardly projecting edge or pouring spout, which in turn has the disadvantage that the canisters can not be stacked on top of one another because the upwardly projecting canisters are stackable Pouring spout prevents a secure state of a further can be arranged about it. In order for such canisters to be arranged one above the other, for example, between each two groups of canisters to be stacked, a plate is arranged which rests on the caps of the lower group closing off the pouring openings and provides a stable, flat surface on which the respective upper canisters are placed can. The need for additional However, plates increase transport and storage costs and make handling difficult. Also, the arranged on the plate canisters are only expensive to secure against accidental slipping. A possible cost advantage through the use of these conventional, completely emptying canisters is at least largely nullified by the lack of stackability.

Against the background of this prior art, it is therefore an object of the present invention to provide a well-stackable but completely emptied canister. According to the invention, the present object is achieved by a canister for the storage and transport of flowable material, having a bottom side, an upper side and at least one side wall connecting the underside and the top side and defining the canister circumference, and a pouring opening closable with a cap, wherein the underside spaced-apart base portions and the top surfaces have receiving surfaces, which are spaced from the pouring opening, wherein the top has a local maximum at which the pouring opening is arranged, and wherein the bottom has a pointing in the direction of the canister interior recess, of which the local maximum the top and the closed with the cap pouring a second identical canister are at least partially receivable. Strictly speaking, the term "local maximum" in the context of the present invention strictly speaking always refers to the inner surface of the upper side, which, however, is an identical image of the upper side, if it has a uniform wall thickness and apart from a grip section.

If the pouring opening is arranged at a local maximum of the upper side, this local maximum during a pouring operation corresponds to a local minimum on the inner surface of the upper side, in which the canister content collects or in the direction of which the canister contents flow. This allows complete emptying of the canister contents. Not necessarily, the local maximum of the top must also be the absolute maximum or the only local maximum of the top, although this is generally advantageous. Another maximum well away from the pour opening will not prevent complete emptying if the container is tilted over one side and substantially emptied and turned upside down just prior to complete emptying.

For the purposes of the present invention, it is therefore sufficient if the local maximum is arranged and configured such that, in the case of a pouring operation, ie with a corresponding inclined position of the canister, the entire canister contents are directed in the direction of the pouring opening. is wegbar. This avoids that a portion of the canister contents during pouring in other possibly existing local maxima of the top collects, as long as they are in the region of the relatively tilted when tilting the canister area of the top. If necessary, the transfer and discharge of a portion of the canister contents which has accumulated in a further local maximum of the top of the upside-down canister can also be achieved by tilting the canister back and forth.

A "local maximum of the top" refers to an orientation of the canisters with its footprint on a flat, horizontal floor, where the local maximum actually refers to the interior surface of the top of the canister located within the canister interior. Thus, a local maximum of the inner surface of the upper side simultaneously corresponds to a local maximum of the outer surface of the upper side A local maximum within the meaning of the invention also comprises a saddle point in which part of the canister contents can collect during a pouring operation.

Characterized in that the underside of the canister has a pointing in the direction of the canister interior and spaced from the Stanflächenabschnitten depression, of which the local maximum of the top and the closed with the cap pouring a second identical can be accommodated can be stacked identically one another canisters , The multiple identical canisters can be arranged so space-saving and safe one above the other for transport and / or storage. A plate for stacking stacked, as in conventional canisters, is thus not necessary in the canisters according to the invention. If two canisters according to the invention are stacked on top of each other, then the receiving surfaces of the upper side of the lower canister engage with corresponding surfaces of the underside at least in sections. Depending on the design of the top and bottom, the receiving surfaces of the lower canister can either engage with the base surfaces or with the depression of the underside bounding surfaces of the upper canister. The weight of the upper canister is thus distributed over the corresponding receiving surfaces on the lower canister.

For the purposes of the present invention, a cap means any device with which the pouring opening of the canister can be closed in such a way that the contents of the canister can not escape through the closed pouring opening. In particular, a cap may be a screw cap, a plug or a seal, the latter also on the pouring opening can be glued on. Often under a (screw) cap additionally provided a closure seal.

In a further embodiment, the canister may have a rectangular or other polygonal or even a circular cross section in a plan view of the upper side. Canisters with a rectangular cross-section can be particularly space-saving next to each other and arranged one above the other, so that a high packing density can be achieved.

In one embodiment, at least two receiving surfaces are provided on the upper side on opposite sides next to the pouring opening, which have no or a positive slope in the direction of Ausgießoffnung. The receiving surfaces interact with corresponding surfaces on the underside of a similar canister, so that the two canisters are stacked securely on top of each other. If the receiving surfaces have no or a positive slope in the direction of the pouring opening, the canister contents during a pouring process along the inner surface of the receiving surfaces can flow only in the direction of the pouring opening. If the receiving surfaces are arranged on at least two opposite sides of the pouring opening, this causes a symmetrical load distribution when stacking canisters of identical construction. In connection with the engagement between areas of the local maximum of the lower canister and the recess of the upper canister can also be effected a centering of the canisters. In addition, during a pouring operation, the canister contents may flow from each of these sides toward the pouring spout.

In order to make it easier to pour out the canister contents, an embodiment is provided in which the pouring opening is offset on one side from the top of the canister in the plan view, between the pouring opening and the nearest side wall section and the adjacent sections of the side wall and in the vicinity of the pouring opening no further local maximum is present at the top. For the purposes of the present invention, the "closer environment" of the pouring opening is the environment which lies in a top view within a circle concentrically arranged around the pouring opening whose radius is at most twice the smallest distance between the center of the pouring opening and the nearest sidewall of the canister.

In one embodiment, it is provided that the canister has a substantially rectangular cross section in plan view from above and the pouring opening is offset towards one of the four side walls of the canister, wherein between the pouring opening and the next gen side wall and the adjoining sections of the adjacent side walls no further local maximum of the top is present. During pouring, such a canister is usually tilted over the pouring opening at the nearest side wall, so that without the presence of further local maxima between the pouring opening and the nearest side wall of the canister is completely emptied.

In a further embodiment, the upper side between the pouring opening and the nearest side wall section has an edge section extending approximately perpendicular to the side wall section as a receiving surface. This edge section can be brought into engagement with corresponding base sections of the underside of a container of identical construction, so that they can be stably stacked on top of one another.

Particularly when the edge section extends in the circumferential direction along a part of the circumference, preferably along more than one third of the circumference, a structurally identical canister can be securely placed on the edge section of a canister arranged thereunder, with base sections configured correspondingly on the underside. Conveniently, the edge portions may comprise a plurality of spaced-apart portions, but preferably extend in their entirety along more than one-third of the circumference. It has proven to be expedient in one embodiment that the edge section comprises at least two sections arranged on opposite sides of the pouring opening, since in this way the edge sections can be brought into engagement particularly well with corresponding base sections of the underside. In order for the weight of a canister to be distributed to the top of a canister disposed thereunder, it is useful if, in one embodiment, the receiving surfaces comprise at least 10%, preferably at least 20%, of the cross-sectional area of the canister. In addition, such sized receiving surfaces provide sufficient space to engage with boundary surfaces of the existing on the underside of a similar canister recess. The proportion of the receiving surface related to the cross section is at most 80%, preferably at most 60% and preferably less than 50%.

In one embodiment, a step is provided between a side wall portion and the receiving surface. The step prevents, if it is taken up by the recess of the underside of a similar canister, that two superimposed canisters can slip against each other. Moreover, in a further embodiment it is provided that the canister has a handle connected to the upper side, which can form an additional receiving surface, which is provided for engagement with a complementary surface in a recess on the underside of another, similar to be stacked canister is. An additional receiving surface causes the weight force acting on the top of a canister to be distributed more evenly. The top of the cap, with which the pouring spout is closed, may be part of the additional receiving surface in one embodiment. The receiving surface is enlarged in this way, so that the weight is more evenly distributed on the top of the respective canister. In this case, the handle may be hollow or made of solid material, the former does not necessarily mean that the volume of the hollow handle is part of the canister volume. For example, the cavity of a handle may be separated from the interior volume of the canister by squeezing the neck at the top.

In one embodiment, it is provided that the recess of the underside is at least partially configured complementary to the receiving surfaces of the top. In particular, the recess of the underside and the receiving surfaces of the upper side of two identically constructed canisters can be brought into engagement with one another like a key-lock principle. The key-lock principle ensures a precise alignment of containers stacked on top of one another and prevents slippage of several identically arranged canisters arranged one above the other.

In another embodiment, the recess of the bottom extends in a side view over the entire diameter of the canister. In this case, however, the recess does not have to have a uniform depth, but is advantageously adapted to the variation of the height of components, such as the pouring opening with cap and a handle. In particular, the bottom of the recess may have an outwardly projecting portion which is provided for the engagement between a pour spout and a handle portion of an underlying canister.

For improved stability of the canister, in one embodiment, the sidewall and / or corner regions of the canister have a plurality of narrow, flat grooves extending vertically from the top to the bottom. Furthermore, holding means, such as ropes, cords or straps, can be introduced into the grooves with which canisters stacked one above the other can be fixed in their respective position. In this case, the grooves or beads extending vertically from the upper side to the lower side prevent the fastening means arranged in the grooves from slipping.

If a canister according to the invention has, for example, a circular cross-section in a plan view of the top, it is particularly expedient if the vertical grooves extending from the top to the bottom of the canister are provided diametrically opposite one another and preferably along the entire circumference. In the event that the canister has a rectangular cross-section, the vertical grooves extending from the top to the bottom are expediently arranged at the opposite corner regions of the canister.

In a further embodiment, it is provided that the circumferential side wall has at least two recessed grips arranged at a distance or opposite one another. It can be z. B a smaller canister with the recessed grips are held better in a pouring process.

FIG. 1 shows an embodiment of the present invention, wherein FIG. 1 a is a side view, FIG. 1 b is a plan view of the front side, FIG. 1 c is a plan view of the underside and FIG. 1 d is a plan view of the upper side of a canister 1 according to the invention. The canister 1 for the storage and transport of flowable material has a bottom 2, a top 3 and at least one of the bottom 2 and the top 3 connecting and the canister circumference defining side wall 4 and a closable with a cap 5 pouring opening 6. The underside 2 of the canister 1 comprises spaced-apart base sections 7 and the upper side 3 receiving surfaces 8. The receiving surfaces 8 are spaced from the pouring opening 6 and are arranged on two opposite sides of the pouring opening 6. In this embodiment, the receiving surfaces 8 in the direction of the pouring opening 6 on a positive slope. The receiving surfaces 8 are recognizable substantially triangular surfaces which can be brought into engagement with corresponding boundary surfaces of the recess 9 of the underside 2 of a further identical canister 1. In addition, a plurality of stacked canisters 1 through the receiving surfaces 8 and the corresponding boundary surfaces of the recess 9 of the bottom 2 are arranged one above the other centered.

Top 3 has in all the canisters of the present an elevation, which is here precisely referred to as a local maximum, on which the pouring opening 6 is arranged, wherein the underside 2 has a pointing in the direction of the canister interior and spaced from the base sections 7 recess 9 of which the receiving surfaces 8 of the upper side 3 and sealed with the cap 5 pouring opening 6 of a second identical canister 1 are at least largely receivable, as indicated in Figure 1 a.

The canister 1 has in a plan view from above a substantially rectangular cross-section, wherein the pouring opening 6 is offset to one of the four side walls 4, wherein between see the pouring opening 6 and the nearest side wall 4 and the adjoining portions of the adjacent side walls. 4 no further local maximum of Top 3 is present. That is, in particular, the inner sides of the receiving surfaces 8, when the canister is placed by 180 ° on the head, no depressions or depressions, in which any befindlichem in the canister 1 flowable material could accumulate during a pouring process.

As can be seen particularly clearly in FIGS. 1 b and 1 d, the upper side 3 between the receiving surfaces 8 arranged on opposite sides of the pouring opening 6 and the side wall 4 has two edge sections 10 which run approximately perpendicular to the side wall 4 and serve as a further receiving surface 8 extend over more than a third along the circumference, namely along three sides of the roughly rectangular canister cross-section.

The receiving surfaces 8 and the associated edge portions 10, on which stand surfaces at the bottom of a stacked canister, comprise more than 20% of the cross-sectional area of the top 3 of the canister 1, so on the one hand enough space for arranging a similar canister 1 on the Top 3 is present and on the other hand, the weight of the upper canister 1 on the top 3 of the disposed below the canister 1 is well distributed. In addition, a step 15 is formed between the receiving surfaces 8 and the edge portions 10, which prevents accidental slipping stacked canisters 1 when the step 15 is engaged with a portion of the complementarily shaped recess 9 of another identically constructed canister 1. As shown in FIG. 1 a, the handle 1 1 connected to the canister 1 and the pouring opening 6 closed by a cap 5 form a common further receiving surface 8, which runs essentially perpendicular to the side wall 4. When the bottom of a canister rests on this additional receiving surface 8, this serves to better distribute the weight force exerted by a second upper canister 1 on a first canister 1 arranged thereunder.

Conveniently, the recess 9 of the bottom 2 is designed so corresponding to the receiving surfaces 8 of the top 3, so that two identical canisters 1 can be arranged one above the other, that the receiving surfaces 8 of the first canister 1 with the recess 9 of the second canister equal to a key lock Principle, that is complementary and fit exactly in each other. In all the figures 1 a to 1 d, but in particular in the figures 1 c and 1 d, a plurality of narrow, shallow grooves or beads 13 can be seen extending vertically to stabilize from the top 3 to the bottom 2 and in the corner areas 12 of the canister 1 are arranged.

A further embodiment of the invention is shown in FIGS. 2a to 2d. Figure 2a shows a side view, Figure 2b is a plan view of the front, Figure 2c is a plan view of the bottom 2 and Figure 2d is a plan view of the top 3 of the canister 1. The canister 1 for the storage and transport of flowable material has a bottom 2, a top 3 and at least one bottom side 2 and the top 3 connecting and the canister circumference defining side wall 4 and a pouring opening 6. The pouring opening 6 is closable with a cap 5 and arranged at a local maximum of the top 3, as shown both in Figure 2a.

So that a plurality of identical canisters 1 of this type are stackable, here also the underside 2 has a recessed in the direction of the canister interior recess 9, from which the receiving surfaces 8 of the top 3 and closed with the cap 5 pouring 6 of a similar canister 1 in sections receivable are, as it is also indicated by way of example in Figure 2a. The receiving surfaces 8 are arranged on opposite sides of the pouring opening 6 on the upper side 3, wherein the receiving surfaces 8 from the side walls to the pouring opening and in the direction of the pouring opening 6 have a uniform positive slope. A flowable material located in the canister can therefore flow in the direction of the pouring opening 6 along the inner surfaces of the receiving surfaces 8 arranged inside the canister during a pouring operation. In this embodiment, the receiving surfaces 8 are essentially triangular surfaces which, in this case, can be brought into engagement only with the corresponding, inclined surfaces of the recess 9 of the underside 2 of an identically constructed canister 1. The standing surfaces 7, with which the canister 1 rests on a level floor, do not come in the stacking of such canisters 1 with the receiving surfaces into engagement. Due to the adapted inclination of the receiving surfaces 8 and the oblique boundary surfaces 16 of the recess 9 a plurality of identical canisters 1 can be arranged one above the other centered. The oblique surfaces 8 and 16 also prevent the superimposed canisters 1 from slipping against one another. The pouring opening 6 in a plan view from above on one side to the side wall 4 of the canister 1 is added. In addition, between the pouring opening 6 and the nearest sidewall section 4 and the adjoining sections of the side wall 4 and in the vicinity of the pouring opening 6 no further local maximum at the top 3 available. During a pouring operation in which the canister 1 is first tilted and then "held upside down, the pouring opening 6 is at a local minimum, so that the canister contents can flow completely out of the canister 1 through the pouring opening 6.

A connected to the canister 1 handle 1 1 is so squeezed that this is hollow although he can not fill with flowable material from the canister interior. In this case, the upper side of the handle 1 1 forms a further receiving surface 8 extending substantially perpendicular to the side wall 4, which can be brought into engagement with the recess 9 of a further canister 1 of identical design. In a state in which a plurality of identical canisters 1 are arranged one above the other, causes by the handle 1 1 and sealed with the cap 5 pouring opening 6 further receiving surfaces uniform distribution of arranged on the top 3 of another under the canister 1, identical Canister 1 acting weight.

The recess 9, which is arranged in the underside 2 of the canister 1, extends in a side view over the entire diameter of the canister 1. The underside 2 has two spaced-apart base sections 7, with which the canister 1 on the ground or, im Case of the embodiments of Figures 1 and 3, can be placed on another canister 1.

For stabilization, the canister 1 has a plurality of oppositely disposed grooves 13 which extend vertically from the top 3 to the bottom 2 of the canister 1. In this case, the grooves 13 in the canister 1 with a rectangular cross section, as seen in Figures 2c and 2d, arranged in the corner regions 12 of the canister 1.

Various views of a further canister 1 according to the present invention are shown in FIGS. 3a to 3d. Thus, FIG. 3a shows a side view, FIG. 3b shows a front view, FIG. 3c shows a plan view of the underside 2 and FIG. 3d shows a top view of the top side 3 of the canister 1. The canister 1 has a bottom side 2, a top side 3 and at least one has the bottom 2 and the top 3 connecting and the canister circumference defining side wall 4 and a pouring opening 6. As indicated in FIG. 3 a, the pouring opening 6 can be closed with a cap 5. In addition, the canister 1 comprises on its top 3 a local maximum at which the pouring opening 6 is arranged. As shown in Figure 3d, top 3 also has two arranged on opposite sides of the pouring opening 6 receiving surfaces 8, which are designed triangular, each of which at one corner of the receiving surfaces 8, the Ausgießöff- 6 adjacent. It can be seen in FIGS. 3a and 3b that the receiving surfaces 8 have a positive gradient pointing in the direction of the pouring opening 6. Due to the positive slope of the canister contents in a pouring process flows in the direction of the pouring opening 6, so that the canister 1 is completely emptied and no remainder of the canister contents in the canister 1 remains.

The canister 1 has in a plan view from above in approximately a rectangular cross section, wherein the pouring opening 6 is arranged on one side to one of the four side walls 4 offset. Between the pouring opening 6 and the nearest side wall 4 and the adjoining portions of the adjacent side walls 4 no further local maximum of the top 3 is present.

The upper side 3 further comprises an edge portion 10, which extends as a further receiving surface 8 in the circumferential direction along three sides of the canister 1, as shown in Figure 3d. In this case, the edge section 10 comprises two sections which are arranged on opposite sides of the pouring opening 6 and which can be brought into engagement with the standing surface sections 7 of a further identical canister 1 when stacked on top of one another (as is also shown, for example, in a schematic partial sectional view of FIG In connection with another embodiment). The underside 2 of the canister 1 has a pointing in the direction of the canister interior recess 9, from which the receiving surfaces 8 of the top 3 and sealed with a cap 5 pouring opening 6 of a second identical canister 1 are partially receivable. Furthermore, with the top 3 of the canister 1, a handle 1 1 is connected to the cap 5 closed pouring opening 6 forms a further receiving surface 8, which is arranged at a common height and perpendicular to the peripheral side wall 4. By engaging this further receiving surface 8 with a corresponding surface of the recess 9 of the bottom 2 of another similar canister 1, the weight of the upper canister 1 can be distributed to the top 3 of the further identical canister 1. The canister 1 also has two recessed grips 14 which are arranged circumferentially on opposite sides of the rectangular canister 1 in the side walls 4, so that the canister 1 can be kept well, inter alia, in a pouring operation.

In order to increase the stability of the canister 1, this has in its corner regions perpendicular to the top 3 to the bottom 2 extending beads 13.

The canister 1 of this embodiment differs from the previously described embodiments only by the shape of the recess on the underside 2 and the elevation or the local maximum on the upper side 3, which are again formed substantially complementary to each other, but not the have oblique receiving surfaces 8 or oblique boundary surfaces 16 of the recess, which receive in the case of the other two embodiments described in stacking support loads. In the present case, such supporting loads are only transmitted through the edge sections 10 and the standing surfaces 7. Common to all embodiments shown that the pouring opening 6 is formed by an upwardly projecting, approximately cylindrical spout.

In the side view of all illustrated variants and in particular in Figures 5 and 6b it can be seen that the bottom of the recess 9 has an outwardly projecting portion 17 which is provided for engagement between a pouring opening 6 and a handle portion 1 1 of an underlying canister 1 is.

A further embodiment is shown in FIGS. 4a to 4d, wherein FIG. 4a shows a side view, FIG. 4b shows a top view of the front side, FIG. 4c shows a top view of the underside 2 and FIG. 4d shows a top view of the top side 3 of a canister 1. The canister 1 has a lower side 2, an upper side 3 and at least one side wall 4 connecting the underside 2 and the upper side 3 and defining the canister circumference. Furthermore, the canister 1 has a pouring opening 6, which can be closed with a screw cap 5. The underside 2 of the canister 1 comprises a recess 9 which points in the direction of the canister interior and two stand surface sections 7 which are arranged on opposite sides of the recess 9 and are spaced apart from one another.

With the base sections 7, a first canister 1 can be placed on the top 3 of a second, identical canister 1. For this purpose, the upper side 3 of the second canister 1 expediently has an edge section 10, with which the standing surface sections 7 of the first canister The canister 1 can be brought into engagement, wherein the edge portion 10 extends in the circumferential direction along more than one third of the circumference. In the plan view of the top 3 of the canister 1 (Figure 4d), it is clear that the canister 1 has an approximately rectangular cross-section and the edge portion 10 extends along three sides of the canister. In addition, it can be seen that the upper side 3 comprises, in addition to the edge section 10, two receiving surfaces 8 arranged on opposite sides of the pouring opening 6, the edge sections 10 being arranged between the receiving surfaces 8 and the side wall sections 4. The edge sections 10 extend approximately perpendicular to the side wall sections 4.

The depression 9 in the underside 2 of the canister 1 is configured such that the pouring opening 6, which is arranged in the local maximum of the upper side 3 and closed by a cap 5, can be received therein by the depression 9. In this case, the receiving surfaces 8 of the upper side 3 abut on complementary to the receiving surfaces 8 formed boundary surfaces 16 of the recess 9 at.

As can be seen from FIGS. 4 a and 4 b, the receiving surfaces 8 have a positive gradient pointing in the direction of the pouring opening 6. Also, the receiving surfaces 8 comprise more than 10% of the cross-sectional area of the canister 1.

In essence, the embodiment shown in Figures 4a to 4d differs from the embodiment shown in Figures 3a to 3d, characterized in that in the embodiment according to Figures 4a to 4d, the canister 1 in the side wall 4 has two oppositely disposed recessed grips 14, the As shown in the side view of Figure 4a, are arranged in the lower third of the side wall 4 and not as in the embodiment of Figure 3 on each of opposite sides has a recessed grip in the lower and upper third.

In addition, the over the entire length of the canister 1 extending recess 9, a plurality also extending over the entire length of the canister 1 reinforcements 18.

A state in which two identical canisters 1 according to the invention are stacked on top of one another in accordance with the embodiment shown in FIGS. 4a to 4d is shown as a perspective partial sectional view in FIG. Perspective views of a canister 1 according to the embodiment of FIGS. 4a to 4d are shown in FIGS. 6a and 6b. In particular, in Figure 6b, the outwardly projecting portion 17 can be seen, which has the bottom of the recess 9 and is provided for engagement between a pour spout and a handle portion 1 1 of an underlying canister 1.
