Description

Plastic bucket

The invention relates to a plastic bucket with a container, a lid which can be arranged on the container in a holding position, and a device for releasing the lid from the container from the holding position, wherein the lid has a radially outer lid rim and the container has an upper container rim.

Plastic container of the type mentioned are known. These often have as a device a Untergriffigkeit on the lid edge or embossed on the lid edge tab with one or more engagement openings for lifting the lid, wherein the lid edge, starting from the location of the sub-grip or the tab, dissolves peeling from the container edge. Here, the lid is arched at the same time. Liquid or doughy products in plastic containers, which can be transported by transport etc. adhered to the lid and already dried can be solved by the buckling of the lid from the lid and fall back into the container. As a result, the consistency of the product is changed in the container undesirable. For certain products or hazardous substances, such as in the case of paints and varnishes, it is essential that the lid closes the container in a particularly secure, firm and tight manner. Therefore, even drop tests are carried out to test the closure. A release of the lid therefore requires a correspondingly large force, which are difficult to be applied by a user and, in particular with repeated opening of the lid, not infrequently can lead to a tearing of the tab.

BESTATIGUNGSKOPIE The object of the invention is therefore to provide a plastic bucket of the type mentioned, the lid of the container is easier to remove.

The object is achieved according to the invention in that the device has a solution element which can be attacked at the edge of the lid and the container rim, and a guide for the solution element in which the solution element can be moved in a working position at least partially circumferentially around the container rim and / or lid rim. wherein the lid edge can be brought by the, solution element over the travel in the solution direction from its holding position to a solution position.

A solution position is understood to mean the position in which the edge of the lid rests on the container edge at least partially almost loosely or loosely and / or is released from the catch when the lid edge and container edge have been locked. The solution direction takes place in conventional plastic buckets usually in the axial direction. With plastic buckets with latched lid, an additional solution force in the radial direction can be used to solve the locking. By driving around the solution element in the circumferential direction of the lid edge is continuously released from the container edge, so that a relatively small force must be expended for detachment. Furthermore, the detachment can take place without buckling or bending of the lid, so that products adhering to the lid can remain on the lid.

Preferably, the solution element exercises in the working position

Solvent force on the lid edge and, opposite thereto, on the container edge, which has a first force component in the axial direction of the plastic bucket. This can be the Solvent be pressed for example with a portion between the lid edge and container edge, which is supported on the lid edge and the container edge, whereby a pushing up or pushing the lid edge or the lid can be effected by its holding position in its solution position in the region of the movable solution element. Hereby, the amount or amount of push-up determined by the thickness of the part of the solution element which spaces the lid edge from the container edge into the release position. Container edge and lid edge, for example, each having a peripheral edge with an axially facing end face, which bear against each other in the holding position or are arranged opposite one another at a small distance and between which the solution element is pressed. This is advantageous, for example, in the case of a container rim, which is conically tapered towards the opening. In the case of an intended latching of the lid with a latching means provided for radial engagement, the latching means can elastically bend upon axial release of the lid. In addition, the latching means may have at their contact surfaces bevels with radial and axial path components, is facilitated by the principle of the inclined plane sliding of the contact surfaces for unlocking in the axial direction.

Furthermore, a formation of the plastic bucket is preferred in the. the. Solvent element., in .der working position a Solvent force on the lid edge and, opposite thereto, on the container edge exerts, which has a second force component in the radial direction of the plastic bucket. The radial force component can for example be advantageously used for opening a lid, which is connected in the holding position via a latching device with the container, wherein the latching substantially perpendicular to the axial solution direction, ie substantially radially.

In a preferred embodiment of the plastic bucket, the guide may have a first guide element on the lid edge and a second guide element on the container edge, wherein the two guide elements are arranged circumferentially and along the travel path and the solution element in the working position under a voltage generating the solution force against the two guide elements supported. Preferably, the two guide elements are arranged in the circumferential direction.

In a further development of the guide, the first guide element may comprise a guide rail which engages in a first guide groove provided on the solution element and adapted to the first guide element. Instead of a guide groove and a guide paragraph may be provided on which the guide rail is supported. Of course, the reverse principle is also possible in each case according to which the first guide element is designed as a guide groove and a rail is provided on the solution element. To the same extent, instead of the guide groove and / or the guide rail, a guide shoulder can be provided.

In a further embodiment of the guide, the second guide element may comprise a guide rail which engages in a second guide groove provided on the solution element and adapted to the second guide element. This can also be a permutation of the guide rail and guide groove and, instead of the guide rail and / or the guide groove, a guide paragraph may be provided. For example, if the first guide rail perpendicular to the travel positively and slidably mounted in the direction of travel in the guide, it may be provided instead of the formation of the second guide element as a rail / groove / guide a rail / sales or sales / paragraph leadership. Through the guide, the solution element should be guided in the intended manner circumferentially on the displacement path with simultaneous detachment of the lid edge of the container edge.

In a preferred development of the guide, the guide rail of the first guide element or of the second guide element can latchingly engage in the longitudinal direction and displaceable in the guide groove respectively provided on the solution element. As a result of the latching, the solution element can be arranged captively on the edge of the lid or on the edge of the container, so that it can not detach from the lid rim or container rim after the lid has been opened by the container.

Preferably, the guide groove is elastically expandable, whereby a simple locking between the guide groove and associated guide rail with a preferably thickened guide rail head can be produced, wherein the guide rail is then mounted longitudinally displaceable in the guide groove. The guide groove may also have a bow shape in which it engages behind a certain portion of the container edge or lid edge in the radial and / or axial direction. The solution element can also be designed overall as a bracket. Here, the solution element can be designed as a separate component of the lid and container, which are brought about by widening lid rim or edge of the container ^"can / ^Here," the solution element be arranged on the edge of the lid or container so that it is covered by a tamper-evident closure so far that it can be operated only after breaking or removing the tamper-evident closure.

In another form of training it is suggested that

Container edge and lid edge can be forcibly guided by the guide over the travel in both circumferential directions. Preferably, in this case the two guide elements can be arranged at the container edge and lid edge at an acute angle circumferentially converging. Thus, an inclined plane is provided with respect to the circumferential direction, over which the solution element can slide off and space edge and container edge space or feed each other. In the process of the solution element in the direction of the crossing point of the two guide elements, the guide elements can thus be pressed apart and thus the lid brought over the travel from its holding position to its solution position, that is solved. When moving the solution element in the opposite direction, ie away from the intersection point, the guide elements can be pulled or pressed against each other or into each other. Thereby, the lid edge can be brought over the travel from the solution position in the holding position and thus closed. Thus, the lid over the solvent element of the container edge, similar to a zipper or bag closure, detached and reconnected to the container edge, wherein the solution element should connect at the end of the travel path in connecting the container edge and lid edge in a rest position described below, in which it can be detached from the container edge and / or the lid edge. The acute angle may be less than 45 °, more preferably less than 20 °. Ideally, the angle can be approximately equal to an acute angle, in which the longitudinal side walls of a closure element, for example, a conventional zipper or bag closure, are supplied to each other.

Preferably, a portion of the travel can be designed as a rest section, in which the solution element can be arranged in a rest position in the guide. In this case, the rest position relative to the working position is characterized in that the solution element is mounted without or under only a minor, a force in the direction of the solution force generating voltage to cover edge and container edge in the rest section. In the rest position, the solution element can thus be stored so that it remains loose relative to at least one of the two guide elements, so that the cover can be lifted off the container and the solution element remains on the edge of the lid or on the edge of the container. In the rest section, the solution element can therefore remain when lifting the lid on the edge of the lid or on the edge of the container or be removed from the plastic bucket. In the formation of the guide with two positively driven guide elements also one of the guide elements in the rest section from the ^" forced operation must be solvable or be pulled out, so that the lid from the container is removable.

To achieve the tension-free mounting of the solution element in the rest section, the second guide element in the rest section may have a course which is designed opposite its course in the remaining travel offset by at least amount against the axial and / or radial solution direction, in which the lid through the Solution element can be brought from the holding position to the solution position. This amount already mentioned above can thus be equal to the distance at which the solution element the two guide elements when detaching the lid spaced from each other, or equal to the thickness of the part of the solution element, which is pushed to the spacing between the two solution elements.

Preferably, the second guide element in the transition to the rest section have a steady course. An unsteady course, for example in the form of a shoulder to compensate for the gradient differences in the rest section and in the rest of travel, would undesirably hinder the displacement of the solution element and require a direct, axial lifting or lifting of the solution element in the solution direction. In this case, a slope may preferably be provided in the transition. This slope or ramp forms an inclined plane over which the solution element is pressed by the rest section in the direction of solution against the edge of the lid, which in turn is thereby pressed into the solution position. The inclination of the slope determines at the same time the necessary force that must be expended in the process of the solution element to overcome the transition. To achieve a force unaufwendiges displacement of the solution element in the transition, the slope should be curved, such as with stretched, S-shape-like Course to be trained.

Appropriately, it may be provided that the travel is limited on one side or on both sides by a rest section. In the case of two rest sections, the solution element can be moved from one rest section via the travel path into the other rest section with the cover being released. After re-closing of the container by pressing the lid on the container, the solution element can be with renewed detachment of the lid in the one rest section back process. Does the guide, as already described above, at an acute angle to each other inclined guide elements over which the lid can be opened with displacement of the solution element and closed again in the opposite direction, so can on the way of the solution element of a rest section in the other an opening and in countermovement take place a closing or closing the lid. If the travel path extends over the entire circumference of the plastic bucket, the two rest sections can coincide. The possible length of the travel can also be structurally dependent on whether a mounting bracket is provided for carrying the plastic bucket, which is articulated in height of the travel path to the container edge. As a result, the maximum travel in the initial direction can each be limited by the articulation points of the support bracket. Furthermore, it is also possible to provide two travel paths extending over a circumferential radius, at the same axial height and adjoining one another, each with a solution element arranged therein, which can be interrupted for example by the articulation points of the handle. Finally, at an intended travel distance of less than the full extent, a rest section may also be provided only at one end. Here, the rest section should be expediently designed as the place in which the solution element, if any, only connected to the lid edge or the container edge remains so that a complete detachment or further spacing of the lid from the container by the user can take place.

Preferably, the solution element is adapted to the contour of the lid edge and / or the container edge. In this case, the solution element can have a different color from the lid edge and / or container edge for better visibility. Furthermore, the solution element may preferably be integrated in the lid rim and / or container rim. For actuation, a pivoting or displacement of the solution element described below may be necessary in this case, so that the solution element protrudes from the edge of the lid or container edge and can be moved circumferentially.

In a further development, the solution element can be at least partially covered by a tamper-evident closure formed in a section of the lid rim or container rim, so that the solution element can be actuated only after the tamper-evident closure has been broken, possibly by pivoting or shifting it from the integral shape with the container rim or lid rim ,

In a preferred embodiment of the plastic bucket, the solution element itself can be designed as a tamper-evident closure. For this purpose, the solution element can be integrally connected to the lid or to the container. For this purpose, the solution element can be connected via webs to the cover or the container, wherein the webs are designed as predetermined breaking points, so that the solution element is movable after breaking the webs. In addition, the solution element designed as a tamper-evident closure can be at least partially covered by the portion of the lid or container rim designed as a tamper-evident closure, so that practically a double tamper-evident closure results. In a preferred development, the sliding element can have a guide section for its guidance on the lid or container rim and a handle section for engagement by a user. Preferably, the handle portion may be pivotally connected to the guide portion. In this case, the handle portion in the working and rest position of the solution element from the container edge and edge of the lid can be pivoted away in a pivoting position. As a result, the user can comfortably grasp the solution element at its guide section and move over its travel path. By pivoting, for example, a laterally provided stop can be overcome, against which the solution element strikes in the untwisted state. As a result, the solution element can be secured against an unwanted procedure.

The grip portion may preferably have an engagement opening for

Have engagement by a user who has in the pivoting position approximately in the direction of the maximum release force.

In another development, radial tabs can be provided as part of a tamper-evident closure on both sides of and circumferentially to the rest section. If the solution element is moved out of its rest position beyond the limits of the rest region in the direction of travel, then the solution element travels over the tabs, which thereby break off and thus indicate in the sense of a tamper-evident closure the procedure of the solution element.

1 to 17, a plastic bucket 1 is shown in various embodiments in side views and associated Schnittverlaufsansichten showing a container 2, one on the Container 2 can be arranged in a holding position cover 3 and a device 4 for releasing the lid 3 of the container 2 has a holding position. The lid 3 is provided with a radially outer lid edge 5 and the container 2 with an upper container edge 6. In the embodiments of the plastic bucket 1 presented here, the cover 3 is supported via an inwardly extending support groove 7 on a substantially axially upwardly extending support web 8 of the container edge 6, whereby the lid edge 5 is guided at the same time on the container edge 6. (In the drawing, obliquely designed lines have an unintentionally stepped course due to insufficient digital resolution).

The device 4 has a solution element 9 which acts on the lid edge 5 and on the container edge 6. In addition, a guide 10 is provided for the solution element 9, in which the solution element 9 in a working position at least partially circumferentially in the initial direction around the container edge 6 and lid edge 3 is movable. By the method of the solution element 9 via a travel path 11, the lid edge 5 can be brought by the solution element 9 in the solution direction 1 from its holding position into a solution position.

In Figures 1, 5, 7, 9, 11 and 14, the solution element 9 is shown in a rest position. In FIGS. 3 and 16, the solution element is shown in a position displaced from the rest position, the solution element in FIG. 3 being in the working position and being displaced from the rest position to the working position in FIG. The solution element 9 exerts in the working position a solvent force on the lid edge 5 and, opposite thereto, on the container edge 6, through which the lid 3 is raised from its holding position to a release position. After that, a user can find the one in the solution position Lid 3 without much effort and without bending the lid 3 from the container 2. ^@

The guide 10 has a first guide element 12 on the lid edge 5 and a second guide element 13 on the container edge 6, wherein the two guide elements 12, 13 are arranged circumferentially and along the travel path 11. The solution element 9 dissolves in the working position under a stress generating voltage against the two guide elements 12, 13 from. The progress in the solution process of the lid 3 of the container 2 is inter alia in Fig. 4, a sectional profile IV-IV of FIG. 3 can be read, in which the support groove 7 is displaced by an amount a of the support web 8, so that Support web 8 no longer, as in Fig. 2 on the groove bottom support groove 7 rests.

The travel path 11 has a section designed as a rest section 14, in which the solution element 9 is arranged in the rest position shown in FIG. 1 in the guide 10. In the rest section 14, the second guide element 13 has a course which is designed offset from its course in the remaining travel 11 at least by the amount a against the solution direction 1 in the axial direction, so that the solution element 9 in the rest section 14 is no longer under tension rests against the lid 3. On its traverse 11 from the rest section 14 from the rest position into the working position into the solution element 9 is thus raised due to the increase of the second guide member 13 against the lid edge 6, so that the lid 3 is pressed from its holding position to the release position. The raising of the solution element 9 via the travel path 11 is symbolized here by the curved arrows in the figures. Due to the flexibility of a conventional Kunststoffimers 1 this pressing of the lid 3 is relatively localized limited in the environment of the attacking Solution element 9, so that the force required to lift the lid 3 is relatively low.

The second guide member 13 is formed in this embodiment as a web-like and circumferential to the container 2 extension 15, which is embraced by the solution element like a clip. Thus, the solution element 9 can be moved by bending its clip-like shape over the extension 15. The first guide element 12 is designed as a guide web 16, which is based on the solution element 9. Thus, for the assembly of the plastic bucket in a first step, the solution element 9 can be applied to the second guide element 13. After completion of the plastic bucket 1, the lid 3 can be placed.

The solution element 9 has a plan view of substantially triangular shape, wherein the solution element 9 engages around the second guide element 13 at an upper holding point 17 and two lower holding points 18. Correspondingly adapted, the course of the second guide element 12 in the resting section 14 follows the area which the upper holding point 17 engages in a curved course, while the course of the second guide element 13 in the section in which the lower holding points 18 in the rest position attack second guide member 13, is formed straight ahead and has an oblique transition to the rest of travel 11. As shown in Figures 1 to 4 difficult to remove, the solution element 9 has a flat, elongated shape, which can adapt to the rounded shape of the lid edge 5 and container edge 6 on the triangular shape with the holding points 17, 18.

On the lid edge 5 and container edge 6 are also locking means in

Form of two locking hooks 19 provided with the placement of the

Cover 3 on the container 2 interlock. By pushing up the lid edge 5 by the solution element. 9 takes place unlatching of the latching hooks 19 by the lid edge 5 bends radially outward. This process is assisted by the fact that the latching hook abutment surfaces 20 have mutual abutment with respect to the direction of solution 1, so that the abutment surfaces can slide on one another according to the principle of the inclined plane. The solution element 9 is essentially divided into two sections, a guide section 21 and a handle section 22. The guide section 21 abuts substantially against the container rim 5, while the handle section 22 is arranged perpendicular to the guide section 21 and points with its larger side faces in the direction of the travel path 11. In order for a user can grab the handle portion 22 rather and move it over the solution element 9 in the direction of travel f.

FIGS. 5 and 6 show a second embodiment of the plastic bucket 1, with FIG. 6 showing a sectional view VI-VI according to FIG. The solution element 9 is shown in Fig. 5 in the rest section 14 in the rest position. Furthermore, here, as in the first embodiment of the plastic bucket 1, the second guide element 13 is lowered in its course in the rest section 14 with respect to the remaining travel path 11. In the method of the solution element 9 in the direction of travel f, as indicated by the bent, the direction of travel f symbolizing arrow raised by the second guide member 13, so that the solution element 9 pressed against the lid edge 5 and thus the lid 3 from that shown in Fig. 5 Holding position can be brought into a solution position, not shown here. At the container edge 6, two tabs 21 are formed, which extend radially outwardly and perpendicularly from the travel path 11. The tabs 23 also limit the rest section 14 on both sides. By moving the solution element 9 out of the rest section 14, the respective tab 23 is broken by the solution element 9. Thus, the tabs 23 form a Tamper-evident closure, which indicates whether the dissolution element 9 has only been moved away from the container 2 by detaching the lid 3 from the container 2 from the rest section 14 in order to detach the lid 3. The guide portion 21 of the solution element 9 has a cylindrical shell-like shape. The grip portion 22 in turn extends perpendicular thereto and is equipped with empty grooves 24 for improved grip of the solution element 9.

A third embodiment of the plastic bucket 1 is shown in FIGS. 7 to 10, wherein a substantial aspect is to be shown here during the assembly of the device 4. As shown in Fig. 8a, the solution element 9 is integrally connected at one end to the container edge 6 and still shown in a pivoted from the container edge 6 state. FIG. 7 shows this situation in a side view, with the solution element 9 extending out of the image plane. The solution element 9 has at its free end a clip-like guide groove 25 which snaps into the pivoting of the solution element 9 to the container edge 6 in Montageverschwenkrichtung m on the second guide member 13 of the lid edge 5 in a latching position.

In a further assembly step shown in Fig. 8b, the lid 3 is placed against the solution direction 1 on the container 2, wherein the support web 8 and support groove 7 engage with each other. The latter is shown in Fig. 9 and Fig. 10a, a

Sectioning X-X shown in FIG. 9. In addition, as in the previous embodiment, snap on the lid edge 5 and container edge 6 provided latching hooks 19 into each other. The first guide element is here, as before, web-like design. In addition, the first one points

Guide member 12 a latching hook 19, which with the

Solution element 9 locked. In order to be able to displace the solution element 9, it must, as shown in FIG. 10b, be released from its single-storey connection with the container edge 6, whereby an actuation of the solution element 9 is indicated in the sense of a tamper-evident closure. The grip portion 22, which rests against the retaining edge 6 in FIG. 10a, is articulated on the guide portion 21 of the solution element 9 and, as shown in FIG. 10b, can be brought into a radial, ie horizontal, position in the pivoting direction v. Thus, a user can comfortably grasp the grip portion 22. In the handle portion also has an engagement opening 26 is provided for engagement by the user. In the position of the dissolution element 9 shown in FIG. 10b, the dissolution element 9 is already in a working position in which it has lifted the lid edge 5 by an amount a relative to the container edge β.

FIGS. 11 to 17 show a further exemplary embodiment of the plastic bucket 1. FIGS. 11 and 12 are shown in the release element 9 in the rest section 14 in the rest position. Figures 13a and 13b, in which only the container edge 6 and the solution element 9 are shown, it is clear that the solution element is connected via connecting webs 20 in one piece with the container edge 6. Here, the solution element 9 is shown pivoted to the container edge. In addition, the solution element 9 has a cross-sectional taper 27, by means of which the guide section 21 is designed to be pivotable relative to the grip section 23.

For mounting the device 4, the solution element 9 is pivoted in Montageverschwenkrichtung m against the container edge 6 and comes, as shown in Fig. 13 b, with its handle portion 22 for abutment against the container edge 6. In a further step or simultaneously with the application of Handle portion 22 to the container edge 6 is the Guide portion 21 pivoted into the second guide member 13 of the container edge 6. In a next, not shown here assembly step, the lid 3 is placed on the container 2 so that, as already in the previous example, the locking hooks 19 on lid edge 5 and container edge 6 lock each other and support groove 7 and support web 8 are guided into each other. Furthermore, the lid edge sits with its web-like first guide element 12 on the solution element 9, as shown in Fig. 12. Similar to the previous embodiment, the solution element 9 is released for its actuation of the container edge 6 by its connecting webs 26 are severed, so that here by the severing of the connecting webs 26 an actuation of the solution element 9 is shown and thus the solution element 9 simultaneously Tamper evident closure is used.

Fig. 14 shows in a side view as shown in Fig. 15 situation of the solution element 9 again. The solution element 9 also has in its handle portion 22 also has an engagement opening 28 for easier attack by a user. With a method of the solution element 9 from a rest position or from the rest section 14 in the direction of travel f, the solution element is raised by the rise s of the second guide element 13 against the first guide element of the lid edge 5. In this case, in Figs. 16 and 17, the beginning of the lifting shows.
