EP0478687B1 - Container, in particular for free-flowing products - Google Patents

Abstract

A container, in particular for free-flowing products, has a body (2), a base (3) connected to one side of the body, a lid (4) connected to the other side of the body, a withdrawal opening and a closure element in the form of a slide. The container is easy to handle and childproof, because the closure element (17) has at least two catches (18, 19) which, although located at a distance apart, can nevertheless be gripped by the fingers of one hand, are effective when the slide (12) is in the closed position, and can be released simultaneously by only two fingers.

Description

The invention relates to a container for in particular free-flowing, intended for consumption products with a hull that has an inwardly folded bead on its open side, a lid attached to it, a removal opening and a closure member in the form of a slide with a handle that consists of a Open position can be brought into a closed position in which it is locked by means of a lock acting as a child lock. Such a container is known from DE-A-36 43 600.

Packaging containers with a removal opening which can be closed by a slide, in particular on the lid of the packaging container, are known. The removal opening can only make up a part of the lid and can be used, for example, as a sprinkling opening, metering opening or the like for removing partial quantities, or can also be designed as a full opening if, for example, the filling material is to be removed in one go and decanted or the contents are removed in portions by reaching into the container. While in the former case the slide covers only a partial area on the cover, in the latter case it essentially forms the closure cover itself. Such a slide can be designed as a linear slide or - especially in the former case - as a rotary slide. Packaging containers of this type serve primarily to hold free-flowing products and can be any, in particular also a different from the circular shape, for. B. have substantially rectangular cross-section.

Packaging containers of this type often contain contents which have health-impairing or hazardous properties. This applies, for example, to household cleaners, detergents or the like. Such products, in particular, must not be accessible to small children. In order to ensure a secure closure of the packaging container, it is known to lock the slide in the closed position by means of a lock (e.g. DE-A-36 43 600), but the locking is generally such that it is alone is overcome by the opening movement, be it a linear sliding movement or a rotary movement. Adequate child protection is not provided. This is achieved in another known container (US-A-3 240 373) in that the lock can only be actuated with an additional tool, which is, however, cumbersome. Finally, in cans with a slip lid (US-A-4 520 921) it is known to provide holes on the overlapping apron of the slip lid at opposite locations, into which pins formed on the outer wall of the container engage in the closed position. The wall of the container and the apron of the lid are so elastically deformable that when the cover is put back the pins move back until they reach the area of the holes and engage there. To open, pressure must be exerted on the pins on opposite sides and at the same time the opening movement must be carried out, so that the holes come free from the pins and the cover can be removed completely.

The invention has for its object to provide a packaging container of the aforementioned construction with an all-round bead at the opening edge with an effective child safety device.

This object is achieved in that the cover on approximately opposite sides has the bulges engaging noses, of which at least part of the slide is guided on the cover and between the closed position in which the cover is fixed to the fuselage and the lock is engaged , can be moved into the open position by means of the handle accessible on the top of the lid and after actuation of the catches, in which the lid can be lifted off by releasing the entire open side of the fuselage.

In the embodiment according to the invention, the lid can have the basic shape known from loose slip lids, namely have an edge flange overlapping the container body on the open side with an inwardly drawn-in cover disk. The edge flange is only to be designed so that it overlaps the bead, possibly with a little pretension. In a departure from the known design, the cover in the region of the edge flange has at least two approximately opposite lugs, at least one of which is designed as a slide or is part of one which is operated by means of the handle is movable between an open position and a closed position. In the open position, the lid is placed on the bead, possibly inserted at an incline so that the nose can reach under the bead, and the slide is then moved into the closed position so that he or his nose also pushes the bead on the opposite side Reaches under. The slide can be guided on the underside of the cover by guide elements molded onto the cover. In the closed position of the slide, the lid is connected to the fuselage and the slide is at the same time latched onto the lid, so that even if the container tips over or is lifted, contents cannot escape on the lid. The lid can only be separated from the fuselage by consciously manipulating the handle that moves the slide and by unlocking the lock. In the open position, the entire cross-section of the container is exposed, so that the contents can be removed not only by pouring, but also by means of a portioning vessel.

An advantageous embodiment of the invention is characterized in that at least the nose opposite the slide, which is firmly connected to the cover, is designed as a spring latching nose engaging under the bead on the fuselage. In this embodiment, the cover only needs to be pressed onto the bulge of the fuselage when the slider is retracted, the nose engaging automatically.

Preferably, the nose of the slide is designed as a spring catch so that the cover only has to be pressed onto the fuselage regardless of the position of the slide, but in particular even when the slide is closed. This is especially true for the bottling plant the advantage that the lid supplied in or behind the filling station can be placed easily, if necessary by machine.

In a further advantageous embodiment it is provided that the spring catches only spring out when the cover is put on and engage behind the bead under tensile forces acting on the cover, so that the container can be lifted on the cover without the latter becoming detached.

In a particularly advantageous embodiment it is provided that the lock has at least two detents arranged at a distance from one another, but in the grip area of the fingers of one hand, which are effective in the closed position of the slide and can only be released with at least two fingers for opening the same.

In this embodiment, the slide is held in the closed position by at least two notches. These two catches must be pressed simultaneously in order to be able to move the slide, in particular to lead it into the open position. The catches are designed and arranged in such a way that at least two fingers are necessary to release the catches and to be able to move the slide. The movement of the slide itself can then not be carried out with the same hand, but the user must also use the second hand. A toddler cannot easily understand these considerations. The securing can be further improved in that the catches are arranged at such a distance from one another that the span to be bridged for the simultaneous attachment of two fingers is greater than the possible span of two fingers of a child's hand. In this case, a toddler has no option to open the slide due to the two-handed operation required. The rest can held in any position in the closed position and brought into the unlocked position, for example by pulling, pressing, turning or the like.

The two catches can be offset next to one another on a line perpendicular to the direction of movement of the slider or one behind the other or in alignment in the direction of movement of the slider. The type of arrangement depends primarily on the shape and size of the container and the aspects to be observed for the removal opening and its arrangement.

In the embodiment according to the invention, the catches at the same time form an effective protection against untimely opening, for example by inadvertent action on the slide, by bumping, tipping over or the like.

In another, but basically equivalent embodiment, there are at least two spaced-apart, finger-releasable catches, one of which is effective in the closed position of the slide and the other is arranged such that it is in an intermediate position of the slide with the removal opening still closed locked and can be triggered with the fingers in the intermediate layer.

In the aforementioned solution, two fingers of one hand are also required to release the catches and the other hand is also necessary to move the slide. Here, however, a further deliberate action is necessary in that not both latches can be triggered simultaneously by a single application of the fingers, but either a repeated actuation in the intermediate layer or an actuation that lasts until the intermediate layer is reached is necessary.

This solution principle can be implemented constructively, for example, by the two catches being effective one after the other in the direction of movement of the slide.

In this version, only one catch is effective in the closed position, which must first be released for opening. If the slide reaches the intermediate position at which the removal opening has not yet been released, the second latching takes effect, which must also be released again in order to be able to bring the slide into the open position.

Instead, it can be provided that the two catches are arranged and designed so that one catch is only effective in the closed position, the other in the direction of movement of the slide between the closed position and the intermediate position.

In the aforementioned embodiment, both detents are effective in the closed position. If they are pressed simultaneously with two fingers and only for a short time, one of the catches is triggered, but the other remains effective and must either be pressed continuously until the intermediate layer is reached or must be pressed again in the intermediate layer.

A preferred embodiment provides that the catches are formed from openings arranged on the slide or on the cover and approximately of the same shape and serving as actuators for resiliently locking cams.

This embodiment can be realized constructively, for example, in that the actuators are arranged on resilient tongues.

When the child lock is designed according to the invention, the usual locking of the slide in the closed position can be dispensed with, since this task can be performed by at least one of the catches.

In the case of the second solution concept described above, the design can be such that in the closed position of the slide an actuating member engages in an opening on the slider, while the second actuating member and the second opening are disengaged and only engage in the intermediate position.

In this embodiment, one of the projections must first be pressed into the opening so that the slide can be moved into the intermediate layer. In this the second projection engages in the second opening and must be actuated by a further finger pressure in order to finally bring the slide into the open position.

In another embodiment it is provided that one opening is of the same shape as the actuating member, the other is an elongated hole extending in the direction of movement of the slide between the closed position and the intermediate position.

In the aforementioned embodiment, the one projection remains within the elongated hole until the slide moved out of the closed position has reached the intermediate position. To open it is therefore necessary to either press both actuators at the same time and to allow the pressure on the actuating member guided in the elongated hole to last until the intermediate position, or to actuate the actuating member again so that the slide can only then be moved into the open position.

A further embodiment consists in that the lock is formed by at least one cam which is resiliently arranged on the cover and a locking surface on the slide cooperating with it, and in that the cam also forms the actuating element for the lock.

In this embodiment, the blocking surface on the slide can in turn be an opening into which the cam engages, or else a simple stop surface, for example on the end of the slide facing away from the bead, behind which the cam engages in the closed position. Depending on the direction of the spring action, the cam or its actuating member can be brought into a position releasing the lock by a pulling or pushing movement.

In this, as in all of the embodiments described below, the spring action can be obtained from the elasticity of the material of the cover or slide or by appropriate shaping thereof.

Another solution is characterized in that the lock is formed by at least one toothed bar arranged on the underside of the cover and a corresponding toothed bar arranged on the slide, the latter being able to be disengaged against the spring action by means of an actuating member.

The toothed strips can have an asymmetrical tooth profile, for example be designed like a saw tooth, so that, for example, actuation of the lock is not necessary for closing the slide. In this case, the teeth slide away from one another, but fulfill their locking function when the slide is in the opposite direction.

An embodiment of this embodiment is characterized in that the toothed strip on the cover lies in a plane parallel to the cover surface and that the actuating member for the other toothed strip on the slide also forms its handle.

In this embodiment, the actuator for the lock and the handle for the slide coincide. To open the slide, the actuator must first be pressed down to disengage the toothed strips. Then a sliding movement must then be effective on the actuator to move the slide from the closed position and to be able to lift the lid.

Instead, the lock can also be designed such that the toothed strip on the cover lies in a plane perpendicular to the cover surface. The toothed strips are advantageously arranged so that the actuating movement for releasing the lock and for moving the slide are perpendicular to one another, so that two-hand operation is necessary in any case.

Finally, this embodiment can be modified such that two toothed strips are provided at a distance from one another and with the teeth facing each other and that two toothed strips with one another on the slide turned toothings are provided, which are forced outwards under the spring action into the toothed strips on the cover and come out of engagement by means of two actuating members to be pressed against one another with one hand. In this embodiment, the actuating members of the two toothed strips are pressed toward one another, for example, with the fingers of one hand and the handle of the slide is actuated with the other hand.

In a further preferred embodiment it is provided that the slide is held by a spring in the closed position, which is designed as a resilient kink support with dead center position, in which the slide is held in the closed position, and that the kink support also serves as a lock by the The crest of the kink support forms the actuating element of the lock and can be brought into an unstable position by pressure via the dead center position, in which the slide can be moved by means of the handle.

Such an anti-kink support gives the possibility of injecting the slide directly in one piece with the cover, for example via so-called film hinges. The kink support has a stable position in its one kink position, in which the slide is in the closed position. The slide can therefore only be moved into the open position while overcoming the dead center position. By pressing on the top of the kink, the kink support can be brought over the dead center position into the other kink position, in which it is unstable due to the articulated film hinges, so that the slide can be moved into the open position.

In a further embodiment of the invention, two slides can be provided, each with a handle, each of which is assigned a lock. In this version, too, both locks must be released in order to be able to move the slide into the open position.

Containers of the aforementioned type, in particular large household packs, generally have a handle which is pivotally mounted, for example, on the body of the container or on the lid.

It is preferably provided that the handle also forms part of the lock for the slide and the lock can be released by means of the pivoting movement of the handle.

With this design, the handle is therefore used for a further purpose by simultaneously serving as part of the child safety device.

This can be achieved, for example, in that the lock has a cam which is resiliently arranged on the cover or on the slide and which engages in a receptacle which is arranged on the cover and is open at the top, and in that the handle is pivoted with a section into the receptacle, displacing the cam is insertable. This also provides an extremely effective child safety device, in that the handle, which is obviously used for other purposes, is used for a purpose that is not intended for it and is also not foreseeable by a small child.

The aforementioned securing is particularly effective when the handle, as usual, has a band-shaped cross section, and also the receptacle is correspondingly slit-shaped. The slot forming the receptacle can be so narrow and, in this case, the ledge-shaped cam can be recessed in the receptacle so that it is impossible to actuate the cam by hand, ie it can only be operated by the carrying handle or a correspondingly narrow auxiliary tool the recording can be suppressed.

Since containers of the aforementioned type are bulk packaging, they must be correspondingly inexpensive to manufacture. To achieve this, it is provided, for example, that the lock is connected via a joint to the cover or the slide and is injection-molded together in one piece with them. A one-piece injection molding of this relatively complicated structure of cover, slide and lock with handle, actuating member and guides can be easily achieved by means of an injection molding tool, in which the cover and slide are sprayed in different planes converging in the joints.

In a further advantageous embodiment it is provided that the lid of the container forms, together with the slide, a uniform component that can be retrofitted to the container body. By designing the lid and slide as a single component, this component can be retrofitted as a whole to the open end of a container, for. B. flanging, gluing or sealing.

In the aforementioned embodiment, the cover has at least on two opposite sides of guide surfaces lying one above the other, between which the slide is movable. The guide surfaces are preferably in one piece with the container lid.

For example, the cover can have an annular flange which can be connected to the container body and a wall covering the free cross section of the container body up to the removal opening, the slide being in the open position approximately above this wall and this having the tongues with the actuating members.

In this embodiment, the removal opening thus takes up only a part of the cross section of the container, and is therefore primarily used for portioned removal of the filling material by pouring.

On the other hand, if the container can be exposed over almost its entire cross-section for the removal of the filling material, for example by means of a portion container, it is provided that the lid is essentially designed as an annular flange, the two circumferential projecting into the free cross-section of the container body and the guide surfaces for the Has slide forming guide strips, and that on one of the lower guide strips, the tongues with the actuators and corresponding openings are arranged on the upper guide bar above, which are aligned with the openings in the slide in its closed position and how these are penetrated by the actuators.

The container 1 according to FIG. 1 consists of a body 2 with a rectangular cross section in the exemplary embodiment shown, a bottom 3 which closes the body 2 on one side and is drawn inwards, a cover 4 which closes the opposite opening and a carrying handle 5 which is by means of Rivets 6 is pivotally mounted on the fuselage 2. The container serves, for example, as a large household pack for detergents, dishwashing detergents or the like.

The fuselage 2 has an inwardly folded bead 7 at the opening opposite the bottom 3, as can be seen in more detail in FIGS. 2 and 3. The bead 7 is formed all around and initially stiffens the fuselage 2 in the area of the opening. In addition, it serves to attach the cover 4.

The cover 4 has an edge flange 8 which overlaps the bead 7 from above and a lower-lying cover plate 9 which are formed in one piece. Furthermore, the lid has a nose 10, 11 that engages under the bead 7 on approximately opposite sides. The nose 11 is only designed as a slide 12 which is guided linearly in guides 13 on the underside of the cover plate 9 and has a handle 14 which projects upwards through an opening in the cover plate. The guide 13 can be formed, for example, by spring noses 15 molded onto the underside of the cover plate 9, which engage in parallel slots in the slide 12. By means of the handle 14, the slide can be moved from the closed position shown in FIG. 2 to the left into the open position and the cover 4 can be lifted off the fuselage 2. To put on the cover 4, this is first placed in an inclined position with the nose 10 ahead on the left part of the fuselage, so that the nose 10 engages under the bead 7 there. Then the cover 4 is tilted downwards to the right and placed on the bead 7 and finally the slide 12 is moved back into the closed position. For this purpose, the handle 14 is guided in an elongated hole 16 (see FIG. 4) in the cover plate 9.

In the exemplary embodiment according to FIGS. 1 to 4, child safety in the form of an additional lock 17 for the slide 12 is implemented. In this exemplary embodiment, the lock consists of two catches, each of which is formed by a cam 18 in the form of a pushbutton and an opening 19 arranged in the cover plate 9, into which the spring-loaded cam 18 engages. In this exemplary embodiment, the cam 18 is part of the slide 12, the spring action being obtained from the material elasticity of the slide 12. The distance the cam 18 from each other and from the handle 14 of the slider 12 can be selected so that the slider 12 can only be opened with two hands, for example by pressing the cams 18 down with two fingers of one hand and the slider 12 with the other hand is moved by means of the handle 14.

In the embodiment according to FIG. 5, both lugs 10, 11 are formed as part of a slide 12 and are guided separately from one another in guides 13 on the cover 4. They can be actuated by means of a handle 14 in the same way as the slide 12 according to FIGS. 1 to 4. Each slide 12 is assigned two locks 17, which, however, act collectively on both slides. The locks 17 in turn have cams 18 which pass through openings 19 in the cover plate 9. The cams 18 are part of strips 20 which are held under spring action in the locked position and act against stop surfaces 21 on the slides 12. By pressing the cams 18, the strips 20 disengage from the stop surfaces 21 so that the slides 12 can be opened. Consequently, the cams 18 must first be pressed with one hand and then the handles 14 can be grasped with the spread fingers of one hand and pulled against one another in order to move the slides 12 into the open position.

In the exemplary embodiment according to FIG. 6, in turn only one slide 12 is provided, to which two locks 17 are assigned. The locks 17 consist of a toothed strip 22 which is arranged on the underside of the cover or in openings in the cover 4, the toothing of which is facing one another and is essentially perpendicular to the cover plane. Corresponding toothed strips are hereby arranged on the slide 12 via resilient arms 23, each of which has an actuating member 18 which extends through the cover plate 9 upwards. The spring action of the arms 23 is designed such that the toothed racks formed on them engage the toothed racks 22 on Lid 4 are held. By pulling the two handles 18 towards the center of the container, the toothed strips can be disengaged and the slide 12 can be opened by means of the handle 14. The toothing is preferably designed so that it does not hinder the closing of the slide 12, but excludes an opening without pressure on the actuators 18.

In the embodiment according to FIGS. 7 and 8, the slide 12 is again assigned two locks 17, which in turn are designed as toothed strips 24. In this case, however, the toothed strips 24 are arranged in a plane parallel to the cover plate 9 on the underside of the cover 4. Toothed slats 25 are in turn formed by resilient arms 25 toothed strips 26, which engage with the toothed strips 24 on cover 4 under the action of the spring force. At the end of the toothed strips 26 a handle 27 is arranged, which reach up through openings 28 in the cover plate 9. The handles 27 also form the actuators for the locks 17. By pressing the handles 27, the lock is first released and then the slide 12 is brought into the open position by thrust.

In the exemplary embodiment according to FIG. 9, two sliders 29 arranged parallel to one another are provided, the handle 30 of which in turn engages through openings 31 in the cover plate 9. Furthermore, a lock 17 is provided on each slide, which is formed, for example, from a slot 31 formed in the cover plate 9 and a strip 32 engaging therein on the slide. Here, too, a combined push and push movement is necessary to bring the slide into the open position. In the exemplary embodiment according to FIG. 10, the slide 12 is again seated in guides 13 and a handle 14 formed on it extends through an elongated hole 16 in the cover plate 9. In this exemplary embodiment, the lock 17 is of a type which also has the actuating member Cam 33 formed, which cooperates with a locking surface 34 on the side opposite the closing edge of the slide. The cam 33 is integrally formed on the cover plate 9, specifically on a section 35 which is curved downward and is prestressed in this direction and which urges the cam 33 into the locked position. By pulling the cam 33, the locking surface 34 of the slide 12 is released and the slide can be moved into the open position by means of the handle 14.

In the exemplary embodiment according to FIG. 12, the slide 12 is injection molded onto the cover 4 via an articulated support 36. The slide 12 also has the handle 14, which in turn engages in an elongated hole 16 on the cover plate 9, but in this case is additionally guided, for example in longitudinal slots, on the cover plate 9. The kink support 36 with the legs 37, 38 which merge into one another in the kink apex 39 has a stable position, which is shown in solid lines in FIG. In this stable position, the slide 12 in the closed position cannot be moved by means of the handle 14. By pressing on the top of the kink, as indicated by direction arrow 40, the kink support 36 can be bent downward (indicated by dash-dotted lines). In this position, the two legs 37, 38 can be folded towards one another, so that the slide 12 can be guided into the open position and the cover 4 can be removed. If the slide 12 is moved into the closed position when the cover 4 is in place, the kink support 36 automatically snaps into the stable position according to FIG.

The exemplary embodiment according to FIGS. 13 and 14 has a handle 5, which, however, in a modification to the illustration in FIG. 1, is not articulated on the body 4 of the container, but on the lid 4 in bearings 41. The bearings 41 are located on the mutually facing inner sides of the edge flange 8 of the lid 4. The handle is designed so that it, as from 13 and 14 can be seen, when folding onto the cover lies within the edge flange 8. In the embodiment shown, the band-shaped handle 5 also serves as an aid for opening the lock of the slide. The slider 12 is in turn guided in guides 13 on the underside of the cover and provided with a handle 14 extending through it upwards. The lock 17 is formed in this case by a strip-shaped cam 42 on the slide 12 and a slot-shaped receptacle 43, in which the cam 42 engages in the closed position. The slot-shaped receptacle 43 can be designed so that the cam 42 does not protrude above it. By moving the handle 5 from the position shown in Figure 13 to the dash-dotted position, the handle with its upper band-shaped portion 44 can be inserted into the receptacle 43 and pushed down by the pressure on the handle of the cams 42 from the receptacle 43, so that the Slide reaches the dot-dash position and can be moved into the open position by means of the handle 14.

In the exemplary embodiment according to FIG. 15, the slide 12 is designed as a rotary slide 45 which is mounted on an axis 46 arranged on the cover 4. The rotary valve 45 is circular in the embodiment shown and forms the closing edge or closing surface with the partially circular surface 47, while by turning the edge 48 formed by a circular edge is brought in parallel to the bead 7, in which the lid can be lifted off. For this purpose, the cover has a part-circular opening 49 into which a handle arranged on the rotary slide 45 engages. Protection against rotation, as indicated in FIG. 15, can be obtained by an additional toothing of the rotary valve with the underside of the cover, so that opening is only possible by pushing and pushing on the handle 14. Of course, other types of Use the childproof lock as described above in connection with the rotary valve 45.

While in all of the above-mentioned embodiments the lugs 10, 11 are designed in such a way that the cover 4 can only be put on when the slide 12 is open and the lug 10 must be guided under the bead 7 with the cover being inclined, in the embodiments according to FIGS to 20, the nose 10 arranged on the cover 4 and the nose 11 provided on the slide are designed as spring locking noses 50, 51. In the exemplary embodiment according to FIG. 16, the spring latch 50 is formed on the cover 4 and is designed as a downwardly extending spring strut with a bend 520, with which the spring latch engages under the bead 7. The spring catch 51, which is designed in the same way, is formed on the slide 12. In this embodiment, the cover plate 52 is also pulled upwards relative to the edge flange 8. The transition between the edge flange 8 and the cover plate 52 forms a stacking aid when the sealed containers are placed one on top of the other. In this case, the cover plate 52 has a slot 53, below which the slide 12 is guided, for example on a rib 54. The handle 14 of the slide 12 is accessible through the slot 53. Finally, it is shown in this exemplary embodiment that the inwardly rolled bead 7 of the fuselage 2 is only fastened to the inside of the fuselage 2 with an adhesive, hot melt or the like at the points where it is under the noses 10, 11.

The aforementioned embodiment has the advantage that the cover 4 - regardless of the position of the slide 12 - after attachment to the bead 7 is fixed only by pressure on the fuselage, the spring detents 50, 51 springing inwards and then with their kinked apex 52 underneath engage the bead 7.

In the exemplary embodiment according to FIG. 17, with a cover design similar to that in FIG. 16, the spring catch 51 formed on the slide 12 is also connected to the cover 4. It in turn has a kink apex 52 which engages under the bead 7. In this case, the spring catch 51 also forms a spring 56 which urges the slide 12 into the closed position, in which, for example, a film hinge obtained by material weakening is provided at 57, which always keeps the spring catch 51 in the position shown and thus the slide 12 always in the closed position pulls. The slide 12 can therefore only be opened by actuating its handle 14 and by triggering the lock, not shown here. Conversely, the lid 4, which is separated from the fuselage 2, can be fixed on the fuselage by pressing it onto the fuselage without any further hand movements. In the exemplary embodiment according to FIG. 18, the cover 4 consists of two materials, namely a cover plate 58 with an edge flange 8 made of cardboard or cardboard composite. The cover plate 58 with edge flange 8 thus forms the entire top end. As a separate component, the spring catch 51 is connected to the cover disk 58. For example, the spring catch 51 can be formed as an injection molded part and inserted into an opening of the cover plate 58 by means of a rivet-like head 59. The slide 12 is guided on a slot 59 of the cover plate 58. Here, too, the spring catch 52 on the slide 12 can again be designed as a closing spring similar to FIG. 17.

In the exemplary embodiment according to FIGS. 19 and 20, the functions of the closing spring and the spring latches are separated. The slide 12 with the handle 14 and the locks 17 in turn has a spring detent 52 which, in the exemplary embodiment shown, is designed as a V-shaped spring strut and, in the closed position, as shown in FIG. 20, locks the cover 4 against lifting off. In this embodiment, the lid is also on its underside with a down Reaching, multi-interrupted rib 60 is provided, which lies on the entire inner circumference of the bead 7 and provides an additional seal. The slide 12 is in turn seated in lateral guides 13 which, in the exemplary embodiment shown (FIG. 20), is formed by slots 61 on downwardly extending tabs 62 and lugs 63 engaging in the slots on the slide 12. Furthermore, the slide 12 is provided with a large-area recess 64 for reasons of material savings.

In the exemplary embodiment according to FIGS. 19 and 20, the slide 12 is under the action of a spring 56 urging it into the closed position, which in the exemplary embodiment shown is designed as a bow spring 65. The bow spring 65 has at its connection points on the slide 12 at 66 and in the region of its outer apex 67 kinks in the manner of film hinges. The bow spring 65 is with its end facing away from the slide 12 on the cover 4, for. B. supported on a molded on its underside nose 68.

In the case of the container 1 shown in FIG. 21 with a handle 5, the open end face is closed by a cover 4 which has a linearly guided slide 12. The slide 12 is part of the cover 4 and forms the closure for a removal opening 71.

Between the cover 4 and the slide 12 two spaced-apart locks 17 are effective which hold the slide 12 in the closed position. The detents locks 17 are arranged so that they can only be operated with two fingers of one hand at the same time. To facilitate opening of the slide 12 with the other hand, it has a handle 14 in the form of a gripping surface which, in the closed position, engages flush in a corresponding recess 70 on the cover 4.

The lid 4 in turn has an annular flange 8, by means of which it is placed on the open end face of the container body 2 and permanently attached to it. As can be seen from FIGS. 23 and 24, it has two circumferential guide rails 20, one above the other, between which the slide 12 is guided. The guide strips 20 are designed somewhat wider on one side of the container, where the gripping surface 70 is also located. The locks 17 are also effective in this area.

The locks 17 are each formed by a cam 18 on the cover 4 and an approximately contoured opening 19 on the slide 12. In the exemplary embodiment in FIGS. 21 to 24, the cams 18 are arranged on the lower guide bar 20 of the cover 4 and, furthermore, a further opening 73 is arranged in alignment with the cam 18 on the upper guide bar, into which the cam engages in the closed position as well as in FIG Opening 19 on the slide 12. The cam 18 is seated on a resilient tongue 72, which is punched out, for example, of the lower guide bar 20 so that it has material connection to the guide bar only on one side.

In the closed position, which is shown in solid lines in FIG. 24, the cam 18 extends through the opening 19 in the slide 12 and also engages in the opening 73 on the upper guide bar 20. To open, the cams 18 of both locks 17 must be pressed down simultaneously with the fingers of one hand, the cams 18 deflecting downward due to the spring properties of the tongues 72. The pressure must be applied so that the cams disengage from the openings 19 and 73 so that the slider 12 can be pulled by a finger of the other hand on the gripping surface.

A container 1 for portioning is shown in FIGS. 25 to 28 Removal of the filling material, for example shown by pouring. In this case, a lid 4 is placed on the container body 2, which has a smaller removal opening 71 and a cover disk 74 which closes the remaining cross section. The slide 12 can be brought from the closed position shown in FIGS. 25 and 26 into an open position in which it lies largely above the cover plate 74 and opens the opening 71. For this purpose, the cover 4 has guide strips 20 above the cover disc 74 on opposite longitudinal sides, so that the slide 12 is guided between these guide strips and the cover disc 74. Furthermore, the slide 12 has a handle 14 in the form of a grip tab.

The locks 17 are designed in the same way as in FIGS. 21 to 24. They are formed by cams 18 on the edge flange 8 and openings 19 in the slide 12. The cams 18 are in turn seated on resilient tongues 72, which in this case have been worked out of the cover disk 74. As in the exemplary embodiment described above, the two cams 18 and the openings 19 are arranged next to one another, for example on a line running perpendicular to the direction of movement.

In the exemplary embodiment according to FIG. 29, the slide 12 again has two openings 19 which are arranged and designed in the same way as in FIG. 26. However, the cams 18 are arranged differently. In the closed position, the cam 18 'engages in the opening 19, while the cam 18 "is ineffective below the slide 12. Furthermore, the removal opening 71 is made somewhat smaller by the right edge 75 being displaced further inward. About the removal opening To expose 71, the cam 18 'must first be pressed and the slide 12 must be moved in the opening direction with the other hand by gripping the handle 14. With this displacement, the slide reaches an intermediate position in which the cam 18˝, the tongue 72˝ of the tongue 72 'of the other cam 18' opposite is engaged in the opening 19. The removal opening has not yet been opened in this intermediate position. By pressing the cam 18 "into the associated opening 19, the second lock is also released so that the slide 12 can be moved into the open position. When opening, the cams 18 'and 18" can be pressed one after the other. Is the function of the opening mechanism recognized, but the user can also press the cam 18 'at the same time and engage with the other finger in the opposite opening 19, so that the cam 18 "can not even snap into this opening.

In the exemplary embodiment according to FIG. 30, the removal opening 71 and the cams 18 ′, 18 ″ with their tongues 72 ′ and 72 ″ are designed in the same way as in the exemplary embodiment according to FIG. 29. However, in a modification of this, the opening assigned to the cam 18 ″ is formed as an elongated hole 76, the length of which corresponds to the displacement between the closed position and the intermediate position of the slide 12. In order to open the removal opening 71, the cam 18 ′ must at least first be pressed into the opening 19 so that the slide 12 can be moved into the intermediate position, in which the cam 18 "strikes the opposite end of the elongated hole 76. By subsequently pressing the cam 18 ", the slide 12 can then be moved into the open position. If the user has recognized the opening mechanism, he can press both cams 18 'and 18" simultaneously in the closed position and at least the pressure on the cam 18 "for as long Let it continue until slot 76 has passed this cam.
