Description

The invention relates to a closure device comprising a frame defining an opening, a lid covering the opening in a closed position, and at least first locking means and second locking means. Furthermore, the invention relates to a container with such a closure device.

It is customary today to use active substances, for example from the group of laundry detergents, dishwashing detergents, pharmaceuticals, personal care products, agricultural auxiliaries, building materials, dyes, adhesives or foods, in a flowable or pourable form, which are stored in a container as predosed units. In the field of storage of commercial quantities of these active substances are plastic containers, which may be transparent, inter alia, known.

These containers have said closure device, wherein the frame of the closure device is connected to a container edge whose shape substantially corresponds to the shape of the frame with the container. By the lid of the closure device, the container can then close accordingly.

The locking means are intended to hold the lid in the closed position on the frame, even if external, unintentional forces act on the frame or on the lid. In particular, the closure device should be childproof. A requirement for a child-resistant closure device is that an opening of the closure device is only possible by a certain, predetermined manner and that deviating attempts to open the closure device, if possible, do not lead to success.

From the WO 2014/111284 A1 is a closure device with lid and frame known, wherein the lid is held in a closed position by two arranged on a same edge of the closure device locking means. The locking means each have a latching tab and a latching hook, wherein the latching hook in the closed position of the lid engages behind an undercut of the latching tab to prevent opening of the lid. In both locking means, the locking between the latching hook and locking tab can be solved by an externally accessible actuating element, wherein the actuating element is coupled to the latching hook and the latching tab. By pressing the actuating element in a first direction, for example, the latching hook can be displaced such that it no longer engages behind the undercut of the latching tab. The actuating element and the latching hook form essentially a rigid unit. The child safety of this closure device results from the fact that the two locking means for opening the lid must be unlocked at the same time, which is difficult for a child to realize.

Also, the closure device of WO 2015/090289 A1 has spaced-apart locking means which must be actuated simultaneously to open the lid can. The locking means are arranged so that the lid can be opened by the interaction of both hands of an adult. Here are actuating element in the form of a gripping tab and latching hooks on the one hand and actuator in the form of a pressure plate and latching tab on the other hand also each rigidly connected to each other.

The rigid connection between the externally accessible actuator and the latching hook / latching lug carries the risk that by improper editing of the actuating element by levering, tearing, damaging etc. of the latching hook or the latching tab are affected in such a way that the locking of the respective locking means is solved. Thus, for example, a child could successively solve the locking means, which should actually prevent the child-safe concept.

The invention is therefore based on the object to provide a closure device with lid, frame and locking means, which provides good protection against accidental opening of the lid, childproof and can be opened at the same time easy

The object underlying the invention is achieved with the feature combination according to claim 1. Embodiments of the invention can be taken from the subclaims. The lid of the closure device according to the invention comprises in any case first locking means and second locking means.

The closure device according to the invention is characterized in that the actuating element can be moved in a second direction, which is different from the first direction, without the latching hook or latching tab being moved. In one embodiment, the actuating element is pivotally connected to the locking tab or the latching hook.

If, for example, the actuating element is moved by pressure in the first direction, a coupling between the actuating element and the latching tab causes the locking between Latching tab and the latching hook is lifted. If, however, the actuating element is moved in the second direction, which in one embodiment is opposite to the first direction, this has no or substantially no influence on the position of the latching tab or the latching hook.

In the following, the interaction of actuating element and locking tab will be described. This description applies mutatis mutandis to the embodiments in which the actuating element is coupled to the latching hook. In the description of the interaction of the actuating element and locking tab, the locking tab can therefore also be mentally replaced by the term "latching hook".

In one embodiment, the actuating element has a pressure surface, which rests against the latching tab when the actuating element is moved in the first direction. In other words, when the actuating element is moved in the first direction, the actuating element presses over the pressure surface onto the latching tab so that the latching tab is pressed out of a locking position.

The actuator can be integrally connected by a film hinge with the locking tab. Thus, there is a hinged connection between the actuating element and latching tab, wherein in one of the two possible directions of rotation over, for example, the pressure surface acts a pressure of the actuating element on the latching tab and in the opposite direction of rotation, the actuating element can move without causing the latching tab moves.

For example, in one embodiment, when a child attempts to release the first locking means by attempting to depress the actuator not as provided by predetermined guidance, but by levering it upward by a screwdriver or the like, this will not affect the locking tab , Since the upward levering corresponds to a movement of the actuating element in the second direction, the latching tab remains in its locking position despite the change in position of the actuating element. The improper levering of the actuator can thus not solve the lock between the locking tab and the latching hook or unlock.

In a rest position of the actuating element may be given a gap between the pressure surface of the actuating element and the locking tab. In the rest position act on the actuator no external forces. If the actuating element is moved starting from the rest position in the first direction, this initially has no influence on the position of the latching tab, since first the gap must be overcome until the pressure surface comes to bear against the latching tab. Upon further movement of the actuating element and the locking tab is then moved. In a movement of the actuating element from the rest position in the second direction, however, the gap between the actuating element and the locking tab is larger, with no forces act on the locking tab, which are large enough to move the locking tab from its locking position.

The actuating element may have a substantially rectangular base surface with two longitudinal sides and two end faces extending perpendicular thereto. In one embodiment, each side wall extends on the two longitudinal sides and on one of the end sides. On the front side, on which no side wall is provided, the above-described film hinge can be connected to the rectangular base.

In one embodiment, the actuating element has at least one reinforcing rib. Preference is given to two reinforcing ribs, which are spaced apart and parallel to each other. The reinforcing rib or the reinforcing ribs can form the pressure surface of the actuating element.

The lid may be pivotally connected to the frame with a pivot axis disposed on a first edge of the frame. Preferably, the frame has a quadrangular basic shape, so that in addition to the first edge it also has a second edge as well as a third and a fourth edge. The first edge and the second edge should face each other. The third edge and the fourth edge are then perpendicular to the first edge and the second edge.

The substantially rectangular basic shape should not preclude that one of the four edges or several edges are curved. For example, the second edge facing the first edge with the pivot axis may have an outward curvature (convex curvature) while the other three edges are substantially rectilinear. The corners between two abutting edges may be rounded.

In one embodiment, the first locking means are arranged at the closed position of the lid on the second edge of the frame. By such an arrangement spaced from the pivot axis, the lid can be well maintained in its closed position.

In a preferred embodiment, the second locking means may be arranged with respect to a center axis of the closure device mirror-symmetrical to the first locking means. If, for example, the first locking means are arranged on the second edge of the frame, the second locking means are also arranged on this edge, namely at the same distance from the central axis of the closure device.

The frame may have a circumferential web which defines a support surface for the lid to the outside. If the lid is in the closed position and flat on the support surface, it is difficult or impossible by the circumferential ridge, leverage the cover from the side by a screwdriver.

The frame and the lid can be made in one piece. The closure device is preferably an injection-molded part made of plastic. As plastic any suitable plastic material can be used, preferably plastics are selected from the group of polyolefins, for example polyethylene or polypropylene.

Another object of the invention, the provision of a container that can be opened easily, but at the same time makes improper opening difficult especially by children, is achieved by the combination of features according to claim 12. The container according to the invention is equipped with a closure device in one of the embodiments described here.

Preferably, the container and the closure device are separate components, both of which may be plastic. The frame may be fastened to the container via suitable connecting means (for example latching means). Alternatively, it is possible that the container and at least the frame of the closure device are integrally formed.

1 shows in perspective view a closure device, which is designated in its entirety by 1. The closure device 1 includes a frame 10 and a lid 30 , While the 1 the lid 30 in a closed position represents 3 in a plan view the lid 30 the closure device 1 in an open position. Like the 3 can be taken, defines the frame 10 an opening 2 extending through the lid 30 can be closed. At the closure device 1 it is a one-piece plastic injection molded part. The frame 10 and the lid 30 are about three film hinges 3 connected

The frame 10 has a substantially quadrangular basic shape with a first edge 11 , a second edge 12 , a third edge 13 and a fourth edge 14 on. While the first edge 11 , the third edge 13 and the fourth edge 14 straight line is the second edge 12 curved and slightly arched outwards. The second edge 12 , which is spaced apart from the film hinges, runs like the first edge 11 substantially parallel to a pivot axis 4 passing through the movie hinges 3 is defined. Around this pivot axis 4 lets the lid 30 from the in 3 shown opened position in the in 1 Swing closed position shown. At its edges 11 . 12 . 13 . 14 indicates the frame 10 a plurality of spaced latching means 15 on, through which the frame 10 with a container, as shown schematically in 2 is shown, can connect. The container, marked 50, has a peripheral edge 51 on, through which an upper opening 52 of the container 50 is defined. The closure device 1 and in particular the frame 10 settles on the surrounding edge 51 put. By the locking means 15 can be a firm connection between the container 50 and the closure device 1 getting produced. In the container 50 For example, dishwashing tablets can be filled in, with the lid open 30 from the container 50 can be removed.

The frame 10 has a support surface 16 on top of the lid 30 in the closed position rests. Outwardly, the bearing surface 16 limited by a circumferential, perpendicular to the support surface 16 ersteckenden outer bridge 17 , The outer dock 17 prevents the lid 30 can be easily levered in the closed position from the side by a screwdriver or the like. To the opening 2 hin close to the support surface 16 in the right Angle an inner bridge 18 on, the insert position of the closure device 1 on the container 50 extends in the direction of the container. The outer dock 17 however, extends in the opposite direction away from the container. To the dimensional stability of the frame 10 are several reinforcing elements 19 provided, on the one hand on the contact surface 16 and on the other hand on the circumferential inner web 18 adjoin.

The lid 30 also has a substantially quadrangular basic shape with the basic shape of the frame 10 corresponds. A first edge 31 near the pivot axis 4 , one of the first edge 31 opposite second edge 32 , which is arched outwards, and a third edge 33 and a fourth edge 34 form the said square basic form. A circumferential outer edge 35 is in the closed position of the lid 30 on the support surface 16 of the frame 10 on. At a distance to the circumferential outer edge 35 is a surrounding inner walkway 36 provided, which is such that it is closed position of the lid 30 inside the inner bridge 18 of the frame 10 lies and at least partially faces this.

The closure device 1 further comprises first locking means 70 and second locking means 90 on, as in the embodiment shown mirror-symmetrical to a central axis 5 can be arranged (see 3 ). The central axis 5 runs perpendicular to the pivot axis 4 , Because the second locking means 90 mirror-symmetrical to the first locking means 70 are constructed in the following, only the first locking means 70 described in more detail. For the second locking means 90 the same applies mutatis mutandis.

Referring to 4 making a cut of the closure device 1 along the line IV-IV in 3 at the lid 30 in the closed position, the first connecting means 70 a latching hook 71 and a snap tab 72 on. In the snap tab 72 is a recess 73 incorporated, in which the remaining hook 71 attacks. The snap tab 72 leaves the frame 30 assign it to the second edge 32 of the frame 30 is formed. The latching hook 71 is part of the second edge 12 of the frame 10 , Accordingly, the latch hook can be 71 the frame 10 assign.

4 shows the locking tab 72 in a locking position. In this locking position forms a lower edge 74 the recess 73 an undercut for the latching hook 71 so that it is not possible, the locking tab 72 and with it the frame 30 with the second edge 32 from the second edge 12 of the frame 10 in the direction of the arrow 6 to raise. The locking means 70 thus prevent opening of the lid 30 ,

By an actuator 75 can the latching tab 72 from the in 4 Press the locking position shown. By a force, by the arrow 7 is shown, the actuator can be 75 Press down, it is essentially a pivoting movement about a pivot axis 8th performs perpendicular to the plane of the drawing 4 extends. By the pivoting movement about the pivot axis 8th comes a print area 76 to rest with the locking tab 72 , As a result, in particular, the lower end of the locking tab 72 in the presentation of the 4 moved to the left until the lower edge 74 no longer below the fixed latching hook 71 , but is arranged laterally thereof. In this deformed state of the locking tab 72 is the locking between locking tab 72 and latching hooks 71 unlocked. Now it is possible, as far as a corresponding simultaneous unlocking even with the second locking means 90 took place, the lid 30 to open.

Between the printing surface 76 and the snap tab 72 is a small gap 77 intended. This gap 77 occurs when the actuator 75 is in a rest position, in which no force acts from above. The gap 77 makes it clear that the actuator 75 and the snap tab 72 only by a single connection point here in the form of a film hinge 78 connected to each other. For example, trying the actuator 75 to pick up, so try this contrary to the direction according to the arrow 7 To move up, for example, by a screwdriver into a gap 37 between the actuator 75 and an opposite edge 38 is introduced, so finds only a movement of the actuator 75 around the pivot axis 8th instead of doing so without the operating tab 72 is moved. The levering of the actuator 75 thus has no influence on the locking between locking tab 72 and latching hooks 71 ,

5 shows a perspective view of the basic structure of the actuating element 75 , 5 shows the actuator from below or in a relation to the 4 rotated or turned upside down, leaving a footprint 79 not at the top but at the bottom. It can be seen that on two parallel longitudinal sides and on a perpendicular end face of the base 79 side walls 80 . 81 . 82 extend. Parallel to the two longitudinal sides run two reinforcing ribs 83 . 84 , who share the printing area 76 train, with the actuator 75 against the locking tab 72 suppressed. At the front, on which the actuator 75 has no side wall, closes over the film hinge 78 the upper end of the locking tab 72 at. In 5 is also the pivot axis 8th shown to the the actuator 75 can be turned.

Due to the side walls 80 . 81 . 82 and the reinforcing ribs 83 . 84 represents the actuator 75 a comparatively rigid unit that with the locking tab 72 articulated, not rigid, connected. The only material connection to the locking tab 72 takes place via the hinged film hinge 78 ,

Like that 1 and 4 can be seen, the actuating element 75 a recessed grip 85, which in 5 not shown. Due to a strip-shaped elevation 39 that stretch along the second edge 32 extends, a same outer cross-section as the actuating element 75 and in which the actuating element 75 without offset is so integrated that it does not have the front elevation 39 In addition, the risk is small that any pressure from the top to the second edge 32 to unintentionally unlock the locking means 70 . 90 leads.

The lid 30 has a projection associated with the first locking means 40 on, under the opening of the lid 30 a thumb of a left hand can be positioned. By pressure on the actuator 75 by the index finger of the same hand, which is then placed in the grip 85, the actuator can be 75 Press down so that the locking between the locking tab and the latching hook is released. By the thumb below the projection 40 can then be the lid 30 around the pivot axis 4 the movie hinge 3 swing upwards. Prerequisite is that the other locking means 90 also be unlocked, namely, for example, by the thumb and forefinger of the right hand.
