Description

Locking device and liquid container

Technical Field

The proposed solution relates to a closure device for closing an opening, which is formed between a first closure section and a second closure section.

Background

The closing section can be part of the storage device. The cavity in the hollow body of the holding device can then be closed via the opening closed by means of the closing device. Such safes are for example designed for accommodating items, for example electronic items such as mobile phones, cameras, tablets or laptops or other items of daily life, for example wallets or payment instruments such as credit cards. Such storage devices are used to accommodate and protect articles, in particular against moisture or contamination or also other external influences. It should thus be possible to carry the articles to difficult environments, such as water sports, but also, for example, in operation.

Such a hollow body then has, for example, a cavity formed between the first wall part and the second wall part, in which cavity the object to be accommodated in the holding device can be held. For locking the hollow body, a locking device is then provided, which comprises a first locking element and a second locking element. In one embodiment variant, the first closure element has a first strip extending longitudinally in the transverse direction and is arranged at the first closure section of the first wall, and the second closure element has a second strip extending longitudinally in the transverse direction and is arranged at the second closure section of the second wall. The first and second closure elements interact magnetically attractive together in such a way that the first and second closure sections bear against one another in a closed state in which the hollow body is closed. Such a storage device is known, for example, from EP 2 571 391 B1.

In this connection, it is also known that the first and second closure elements form a closure composite in the closed state of the closure device, which can be adjusted from a release position into a closure position. In the release position of the closure composite, the first and second closure sections can be again moved away from one another in a conventional manner, in opposition to the magnetic force exerted by the first and second closure elements, in order to release the opening. In the locking position, the locking composite and the third locking element cooperate in a magnetically attractive manner, so that the locking composite is held in the locking position, in which the release of the opening is not possible. The locking composite must therefore first be adjusted from the locking position into the release position in order to release the opening again. The adjustment of the blocking composite into the blocking position is effected, for example, by folding or rolling the blocking composite at least once, so that the blocking composite is then held in the folded or rolled-up blocking position by means of the third blocking element.

Although the latching device is effectively secured against accidental opening on the user side and ensures relatively simple operation via magnetic fastening between the latching composite and the third latching member, there is a need for further improvements in such latching devices. In particular with regard to increased loads on the closure device, for example due to increased internal pressure in the cavity closed by the closure device, (increased) shear forces may occur on the closure parts of the closure device, which shear forces may cause the closure composite part to move away from the third closure part and/or the first and second closure sections to separate from one another.

SUMMERY OF THE UTILITY MODEL

The locking device according to the invention is an improvement in this respect over the solutions known from the prior art.

The proposed locking device comprises an additional fastening mechanism via which the locking composite in the locked position is additionally fastened against removal from the locked position.

According to a first aspect of the proposed solution, the locking device additionally comprises a third lock at the first closure section, by means of which the locking composites interact in their locking position in a magnetically attractive manner. The locking position can then be additionally mechanically fastened via an additional fastening mechanism, so that the fastening mechanism prevents the locking composite from being unintentionally dislodged from the third closure.

However, the proposed solution is also advantageous in principle without such a third locking element which interacts magnetically attractive with the locking composite. Accordingly, a second aspect of the solution proposes a locking device in which the closing section is adjusted into the closed position with at least one folding or rolling and the fastening means fastens the locking composite in order to prevent it from moving out of the closed position it thus occupies as a result of the increase in the internal pressure in the hollow body closed by the closing device at the opening. The proposed locking device (in particular independently of the third locking element which interacts magnetically with the locking composite) has therefore proven to be advantageous in order to secure the occupied locking position by at least one folding or rolling-up in order to prevent undesired opening when shear and/or lifting forces act on the first and second locking elements as a result of an increase in the internal pressure at the hollow body which is locked by the locking device. In this case, it is possible to effectively counteract, in particular, shear forces and/or lifting forces via the additional fastening means, wherein the shear forces act in the middle section of the strip of the first and second closure elements in a direction perpendicular to the longitudinal extension direction of the strip and the lifting forces act on the closure composite at the longitudinal end sides and under the action thereof the closure elements tend to move away from one another.

Independently of the embodiment variant according to the first or second aspect of the proposed solution, the fastening means can be designed accordingly for the purpose of being locked in the closed position

Against a lifting force acting on the first and second strip-shaped bodies on the longitudinal end sides and resulting from an increased internal pressure, under which lifting force the longitudinal ends of the first and second strip-shaped bodies lying opposite one another tend to move away from one another and/or

Against shear forces which are generated by the increased internal pressure and which act in a plane extending parallel to the first and second closing sections in the middle region of the first and second strip-shaped bodies at the closure device.

The fastening mechanism can thereby be designed in particular for counteracting shear forces which act between the first and second blocking element, between the blocking composite and the third blocking element or between the blocking composite and the wall opposite the blocking composite in the blocking position.

The proposed solution is based on the basic concept that the closure composite is additionally mechanically fastened in its closure position by means of the closure sections which lie against one another in the closed state, in order to prevent a transfer into the release position, in any case as long as no release force is applied to the closure composite from the user side in a specific predetermined direction of action. This prevents, in particular, accidental opening of the closure composite. The additional fastening mechanism can thus be manually operated so as to be releasable, so that the blocking composite can be readjusted into the release position. Without intentional loosening of the fastening mechanism on the user side, the blocking composite remains blocked, however, from being adjusted into the release position. In this way, a (optionally sealed) closure is provided at the closure section via the first and second closure elements together with their strip-shaped bodies, which closure is mechanically fastened via the fastening mechanism. In the case of a movement away from the locking position, a mechanical securing against this is provided via the securing mechanism, whereby this is understood not only to mean an unintentional movement away by actively acting on the locking device on the user side, but in particular also a (at least partial) movement away from the locking position, owing to the load acting on the locking device which is not applied on the user side.

In the closed position, the first and second closing section can be folded or rolled up, in particular in such a way that, viewed along the path of extension in a cross section perpendicular to the transverse direction, the first and second closing section and thus the wall with the closing section are bent at least once through 180 °.

The strip-shaped body is arranged at the closing section so as to act on the closing section, wherein the first and second closing elements, when in their closed state, cooperate in a magnetically attractive manner such that the closing sections are held in magnetic contact with each other.

In order to provide a magnetic interaction, the first and/or the second strip-shaped body can each be formed from a magnetic material, for example in that the strip-shaped body is formed from a plastic material, in particular a polymer material, or a silicone material, which is mixed with a magnetic material in the form of magnetic particles. Alternatively, the strip-shaped bodies can each accommodate a magnetic system composed of separate magnetic elements, so that the strip-shaped bodies interact magnetically attractive to one another by interaction of the magnetic systems. It is conceivable that each locking element acts permanently, for example in the form of a strip-shaped body with permanent magnet particles and thus made of a permanent magnet material or in the form of a magnetic system of the locking element formed by a system of permanent magnets. Alternatively, however, it is also possible for the blocking element to act permanently and for the other blocking element to act as a ferromagnetic armature, for example, in that the blocking element, which acts in a ferromagnetic manner, is formed as a strip of ferromagnetic material (for example, from a plastic material mixed with ferromagnetic particles) or has a separate ferromagnetic element.

If the closure has a magnetic system of discrete magnetic elements, the discrete magnetic elements can be arranged, for example, linearly next to one another in the transverse direction, wherein the discrete magnetic elements can be spaced apart regularly from one another, for example, in the transverse direction. However, it is also conceivable and feasible for the individual magnetic elements to be arranged in rows and columns by means of a two-dimensional matrix.

In principle, the third blocking element can also have a third strip extending in the transverse direction. For example, the third latch is provided at a different, staggered section of the first wall than the first closure section. The third blocking element can interact in the closed state, for example magnetically attracted, with the first blocking element in order to hold the blocking composite element in the blocking position.

The third closure element can be arranged spatially offset from the first closure section perpendicular to the transverse direction. In this embodiment variant, the third closing element is thus formed with its third strip-shaped body extending parallel to the first strip-shaped body of the first closing element, but offset transversely thereto.

In the closed state, the third strip and the first strip can be in a planar, mutually opposite position, for example with faces facing each other. In this case, the locking elements cooperate in a magnetically attractive manner such that the first locking element is held in a defined positional relationship with respect to the third locking element.

In one embodiment variant, the first and/or second and/or third strip-shaped body of the third closing element is/are formed in an elastic manner. The strip-shaped body can have an increased rigidity in relation to the wall of the hollow body, at which the closure device is inserted, for example, but is elastic in this case, so that it can be bent, in particular about a vertical direction perpendicular to the transverse direction.

Additional connections between the closure composite and the wall connected to the first closure section and/or between the closure composite and the third closure may be provided via the fastening mechanism when the closure composite is in the closed position. The connection between the blocking composite and the third blocking element is closed here, for example, in such a way that in the blocking position a connection between the first blocking element and the third blocking element or between the second blocking element and the third blocking element is provided via the fastening mechanism. The additional connection provided by the fastening means can be designed to absorb shear forces acting on the locking device in a form-fitting manner.

For example, the fastening mechanism has at least one fastener which fastens the closure composite via a form fit to prevent removal from the third closure. The form fit can in principle already be in the locking position of the locking composite. However, embodiments are also conceivable in which a form fit for fastening the blocking composite to prevent removal from the third blocking element is only produced when a specific load acts on the blocking device.

In one refinement, the fastening mechanism has at least two fastening elements which cooperate in a form-fitting manner with one another in the blocking position of the blocking composite in order to fasten the blocking composite against removal from the third blocking element. The at least two fastening elements can also be brought into engagement with each other in a form-fitting manner by means of the closure composite into a closed position, or alternatively at least into a relative position relative to each other, in which relative position the two fastening elements automatically engage into each other in a form-fitting manner when a load is exerted on the closure device.

In a development based thereon, a first fastening element and a second fastening element are provided, wherein the first fastening element is designed to engage the second fastening element from behind in order to fasten the closure composite against removal from the third closure element. By means of the corresponding rearward engagement, which forms an undercut at the fastening means, it is ensured on the one hand that the two fastening elements are effectively fastened to one another in a form-fitting manner. On the other hand, this also makes it relatively simple to implement: the fastener can be disengaged again only by a targeted loosening movement. This prevents the fastening element from being unintentionally detached, in particular in the loaded state of the locking device.

In principle, the fastening element of the fastening mechanism can also be formed on one of the blocking elements. Alternatively or additionally, the fastening element can be formed by a separate component of the closure device from the closure element.

In one embodiment variant, the blocking device comprises at least one magnetic element, under the action of which at least one fastener of the fastening mechanism is positioned in a fastening position in which it can block the blocking composite via a form fit against removal from the third blocking element. The corresponding magnetic element can also be formed here by a magnetic material in the form of magnetic particles. Alternatively, the magnetic element may comprise a permanent magnet which is arranged on the locking device at the respective location.

In the fastening position, the fastening element can already be in a form-fitting engagement in order to fasten the blocking composite against adjustment into the release position, in which the fastening element of the fastening mechanism is positioned under the action of the at least one magnetic element. However, it can also be provided that the fastening element is also in an intermediate position in its fastening position, from which it is only transferred into the engagement position under the effect of an additional load on the locking device, in which engagement position a positive-locking engagement is then formed, which serves as a stop.

In a variant embodiment, it is also provided that the at least one fastening element is already adjusted together into the fastening position by the at least one magnetic element when the closure composite is transferred into its closure position. The at least one magnetic element thus ensures that the at least one fastening element is in its fastening position when the locking composite reaches the locked position.

In an alternative embodiment variant, the at least one fastening element is subsequently adjusted in the direction of the fastening position after the transfer of the closure composite into its closure position. The subsequent adjustment can then be supported by the at least one magnetic element, at least in the last portion of the adjustment path before reaching the fastening position, in order to support the occupation of the predetermined position by the at least one fastening element in the fastening position by magnetic attraction.

In principle, an additional form fit between the closure composite and the wall portion to which the first closure section is connected can be provided in order to secure the occupied engagement position. For example, one embodiment variant provides for this purpose at least one form-fitting element on the closure composite side, for example in the form of a latching projection or a latching tab, which engages into a latching opening on the wall side when the fastening means is in the engaged position.

In one embodiment variant, an additional fastening element is provided at the closure composite, at which at least one fastening element of the fastening mechanism is fixed spaced apart from the first and second closure parts. The fastening element has, for example, a flexible or rigid carrier, at which at least one fastening element is fastened. For example, the fastening element is arranged offset from the first and second closing elements in a spatial direction which runs transversely to the direction of extent of the strip-shaped bodies of the first and second closing elements. The mechanical locking of the locking composite in the locked position can thus be provided via the fastening means provided at the additional fastening element, spaced apart from the first and second locking elements and, if appropriate, also from the third locking element. This includes, for example, in connection with the variants already mentioned above: the fastening element provided at the additional fastening element forms a first fastening element which, in the closed position of the closure composite, is connected in a form-fitting manner to a second fastening element which is provided at the wall connected to the first closure section and is in particular fixed thereto. The first and second fastening means can in particular be parts of a magnetic closure, via which the closure composite is additionally fastened in its closed position to prevent adjustment into the release position.

In one embodiment variant, the fastening mechanism has at least one fastening element which, after the transfer of the closure composite into its closure position, can be adjusted into the fastening position of the fastening closure composite by pivoting about at least one hinge axis. Thus, in the fastened position, the at least one fastener fastens the closure complex in its closed position against removal from the third closure. Here, after the closure composite has been adjusted into the closed position, it can be proposed to pivot the fastener about its hinge axis into its fastening position. In the present embodiment variant, the at least one fastening element is then pivoted into its fastening position, for example, in a targeted manner on the user side, in order to additionally fasten the closure composite.

The hinge axis can be defined, for example, by a hinge via which at least one fastening element is hinged to the closure composite, to the third closure part of the closure device or to a wall connected to the first or second closure section. In this last case, the fastening means can thus be articulated on the front first wall or on the rear second wall in the direction of view (running perpendicular to the longitudinal extension of the first and second strips) of the closure composite present in its closed position.

For example, the hinge axis is defined by a film hinge or film. The pivotable fastening at the closure device can be provided relatively inexpensively here via a film hinge or film. For example, the film defining the hinge axis may be a section of a wall to which one of the closure sections is connected.

In order to keep the closure device as compact as possible, an embodiment variant proposes that at least one fastening element is connected to the third closure element via a film hinge. The at least one fastening element is therefore hinged to the third closure part via the film hinge and does not have to be provided on any separate component.

In one embodiment variant, a form-fitting connection is provided between the closure composite in the closed position and the third closure, via at least one fastener in its fastening position, in order to absorb shear forces and/or lifting forces, in particular. Thus, after the closure composite has assumed the closure position, the fastening element can be pivoted into its fastening position via the film hinge, for example also relative to the third strip-shaped body of the third closure element, and then connected to the closure composite in a form-fitting manner. The fastening means can here be arranged at the longitudinal ends of the third strip via film hinges. For example, the fastening web is formed in the form of a strip, in particular.

For a positive-locking connection via a fastening element in a fastening position pivoted about the hinge axis, at least one receptacle can be provided at the at least one fastening element, into which a further fastening element of the fastening mechanism engages positively in the fastening position. For example, openings are provided for this purpose at the fastening elements, into which openings the projecting pins or webs of the other fastening element engage in the fastening position. Alternatively or in addition, at least one form-fitting element can be provided for at least one fastening element, which form-fits into a receptacle of another fastening element of the fastening mechanism in the fastening position. The corresponding form-fitting element can then be formed here by a pin or a tab which is inserted into a corresponding receptacle of the other fastening element. The further fastening element mentioned above can be formed in particular at the closure of the closure composite, i.e. for example at the first closure.

Alternatively or in addition, the fastening mechanism may have at least one fastening element for the targeted mechanical fastening of the end of the closure composite present on the longitudinal side (with respect to the longitudinal extension of the strip and thus with respect to the transverse direction) to the wall or to the third closure. This fastening of the longitudinal end sides particularly inhibits vertical lifting and, if necessary, additionally shear. Fasteners which can be used for this purpose include, for example, the articulated fasteners already mentioned above. However, this is also to be understood as an alternative embodiment variant in which the fastening means are formed, for example, by means of velcro, O-rings or sleeves which are slipped over the longitudinal ends.

As already mentioned above, the blocking composite with the first and second blocking member in the closed state can be transferred from the release position into the blocking position by pivoting the blocking composite about a pivot axis parallel to the first spatial direction (for example a cartesian coordinate system with respect to the x direction). The locking composite is therefore pivoted about a pivot axis parallel to the first spatial direction, for example by approximately 180 °. The (generated) magnetic force for holding the blocking composite in its blocking position relative to the third blocking element then acts along a spatial axis which runs parallel to a second spatial direction (y) running perpendicular to the first spatial direction. The blocking composite is fastened via a fastening mechanism in this variant in order to prevent displacement from the third blocking element as a result of shear forces, i.e. due to shear forces directed in a third spatial direction (-z), which is perpendicular both to the first spatial direction (x) and to the second spatial direction (y). If a shear force directed in the third spatial direction acts on the blocking composite, the blocking composite is therefore fastened via the fastening means to prevent a transfer in the spatial direction and thus into the release position.

The blocking composite is thus, for example, pivoted out of the release position into the blocking position, in which it is then fastened via the fastening mechanism to prevent a displacement relative to the third blocking part in the third spatial direction beyond an allowable magnitude and thus also a pivoting back. The third spatial direction is in this case exactly opposite to the spatial component along which the locking composite is tilted into the locked position. The securing mechanism can thereby also prevent the locking composite part from being lifted or sheared off from the third locking part as a result of a load applied to the locking device, for example a load due to an increased internal pressure in the cavity locked by the locking device.

One embodiment variant provides that the fastening element, which blocks the locking composite against adjustment in the third spatial direction, is first in the intermediate position when the locking position is reached by the locking composite and can only then be transferred into the engaged position. It can be provided here that the fastening element of the fastening mechanism is (only) positioned in the intermediate position by magnetic attraction when the closure composite is transferred into its closure position.

In one variant, the transfer into the engagement position, in which for example one fastening part of the fastening mechanism engages the other fastening part from behind, is alternatively or additionally supported by at least one (additional) magnetic element. Thus, at least one magnetic element can be provided, under the action of which at least one fastening element is adjusted from the intermediate position into the engagement position. Thus, when the locking composite assumes its locking position, so that the fastening element is present in the intermediate position, the fastening element is supported here under the effect of the magnetic force for further adjustment into the engagement position.

The adjustment of the magnetic support from the intermediate position into the engagement position can also comprise: the bi-stability of the position for the fastener is preset via the magnetic system of the fastening mechanism when the locking composite is in its locked position. Via this, the fastening element is then first held in the intermediate position via the magnetic system. However, if a load acts on the locking device by means of which the locking composite can be transferred into the release position, a slight transfer movement of the fastening element connected thereto causes a change in the magnetic elements which act in an attractive manner with respect to one another and, in conjunction therewith, a magnetically supported transfer of the fastening element into the engagement position. This includes, inter alia: the fastening mechanism is designed to allow a slight transfer movement of the fastening element in the direction of action of the shear force by the action of the shear force acting at the closure composite, which then nevertheless causes a magnetically supported transfer of the fastening element into the engaged position.

Irrespective of whether the fastening elements are magnetically supported from the intermediate position into the engagement position, an embodiment variant can provide that the at least one fastening element can be transferred from the intermediate position into the engagement position by the effect of an increase in the internal pressure in the cavity accessible via the opening. The fastening means is therefore designed in such a way that the fastening means is automatically transferred into the engaged position when an increased internal pressure acts in the cavity, i.e. exceeds a threshold value. This variant is particularly advantageous when the cavity at the liquid container is to be closed by means of a flexible wall via the closing means. After filling the cavity with liquid, particularly during transport or loading, the internal pressure can be increased considerably in this case, so that the fastening element is automatically transferred from the intermediate position into the engagement position at the fastening means of the closure device. In this embodiment variant of the proposed locking device, the locking position of the locking composite is therefore additionally mechanically secured automatically, i.e. without acting on the securing mechanism on the user side, in order to prevent setting into the release position. After the load on the liquid container has been relieved, the resetting of the fastening element into the intermediate position can then also be effected automatically, which also facilitates the release of the fastening mechanism and thus the opening of the closure device. The mechanical fastening of the locking position additionally provided by the fastening mechanism thus has no disturbing influence on the opening of the locking device for the user.

The proposed solution is thus advantageous in particular for use on liquid containers, such as drinking capsules. In one embodiment variant of the proposed closure device, the hollow body of the liquid container, which is designed to receive liquid at the opening, is closed, via which opening liquid can be filled into the hollow body when the closure device is opened. The fastening means of the closure device can in this case resist, in particular, the removal of the closure composite part from the third closure part as a result of the increased internal pressure in the hollow body which is at least partially filled with liquid.

In this connection, it can be provided, in particular, that the hollow body is surrounded by at least one flexible wall, to which the closing section of the closure device is connected. By introducing the liquid into the hollow body, but also by the pressure exerted on the flexible wall from the outside in the at least partially liquid-filled hollow body, no slight shear forces act on the closure at the closure device which closes the opening. By means of the additionally provided fastening means, it is then ensured that such shearing forces do not lead to undesired opening of the closure device.

The proposed solution also comprises a drinking water capsule with one embodiment variant of the proposed closure device, wherein a hollow body designed for receiving liquid is surrounded by a flexible wall portion and the closure of the closure device is arranged at a respective flexible closure section connected to the relevant wall portion.

In one embodiment variant, the first strip of the first blocking element is then enclosed, for example, between an inner layer and an outer layer of the first wall section, which border the cavity of the hollow body to be blocked by the blocking device (berandet). In addition or alternatively, the second strip of the second closing element can be enclosed between an inner layer and an outer layer of the second wall of the hollow body. The respective strip-shaped body can be designed as a solid strip-shaped band, whereby it is located in the intermediate layer between the inner and outer layers so as to be enclosed between these layers and is covered inwardly by the inner layer and outwardly by the outer layer.

In one embodiment variant, the first closing section is formed by an inner layer of the first wall and the second closing section is formed by an inner layer of the second wall. Thereby, the closing section of the respective wall portion is integrally formed at the inner layer of the respective wall portion. In the closed state, the closing sections lie flat against one another and form a sealed closure, so that the hollow body is sealed off, in particular fluid-tight, so that no moisture can reach the interior of the hollow body.

In one embodiment variant, the first wall and/or the second wall are flexible. In particular, the first wall section and the second wall section can be flexible and supple, so that the hollow body is deformed in a flexible, easily deformable manner so as to be able to be matched to the shape of the article for accommodating the article. The hollow body is thus formed by a wall portion, depending on the type of bag, in such a way that objects, in particular electronic objects such as mobile phones or other articles of daily life, are accommodated and can be enclosed in a protected manner. Alternatively, the hollow body is designed for receiving a liquid and is designed, for example, as part of a drinking water bag.

In principle, the first and second wall parts can be parts of a common wall element, to which the first and second closing sections of the proposed locking device are connected. The first and second wall sections can thus be formed in particular in one piece. For example, the first and second wall parts, which are opposite one another in the cross-sectional view, can be formed by a single, one-piece wall element in the form of a blow-molded part.

100, 101 is formed by two

layers

106, 107, from which the inner layer 106 points towards the inner volume of the hollow body 10 and the outer layer 107 points outwards.

The

wall sections

100, 101 are designed flexibly, so that the hollow body 10 is flexible, in particular is flexibly accommodated therein around an object or can expand when a liquid is accommodated in the hollow body 10.

The closure device 2 has three

closure elements

20, 21, 22. A first latch 21 of these

latches

20, 21, 22 is arranged at the closing section 104 of the first wall 100, and a second latch 20 is arranged at the closing section 105 of the second wall 101, so that the

latches

20, 21 extend at the same height along the vertical direction z at the respectively associated

wall

100, 101. The locking

elements

20, 21 cooperate in a magnetically attractive manner such that, in the closed state of the locking device 2, the

closure sections

104, 105, which are formed in each case by the inner layers 106 of the associated

wall sections

100, 101, lie flat and thus sealingly against one another and form a locking composite 2V.

The third blocking element 22 is arranged on a section 102 of the first wall 100 offset from a closing section 104 of the first wall 100 and, viewed along the extension path, is arranged offset laterally in cross section according to fig. 3C from the closing section 104 relative to the first blocking element 21.

The blocking

members

20, 21, 22 each have a

strip

202, 212, 222 which extends longitudinally in the transverse direction x and thus transversely to the vertical direction z.

The locking

elements

20, 21, 22 are designed to interact magnetically in an attractive manner. In the exemplary embodiment shown, the

strips

202, 212, 222 are each formed from a magnetically active material, for example in that the

strips

202, 212, 222 are made of a plastic material or a silicone material, in which magnetically active particles are embedded.

The

strips

202, 212, 222 can each have a permanent magnetic action and then face each other in pairs with poles of different names, so that the

strips

202, 212, 222 are magnetically attracted to each other in the sequence shown in fig. 3C. Alternatively, the strip 212 of the first locking member 21 can, for example, only function as a permanent magnet, while the

other strips

202, 222 are designed ferromagnetically, so that the associated locking

member

20, 22 acts as a magnetic armature. For example, it is also conceivable for the

locking elements

20, 21 to be designed permanently at their

strips

202, 212, while the strip 222 of the third locking element 22 acts ferromagnetically.

As can be seen for example from fig. 3C, the

strips

202, 212, 222 are enclosed between the inner layer 106 and the outer layer 107 of the respectively associated

wall portion

100, 101. In this way, the

strips

212, 222 of the blocking

elements

21, 22 are enclosed between the inner layer 106 and the outer layer 107 of the first wall section 100, while the strip 202 of the blocking element 20 is enclosed between the inner layer 106 and the outer layer 107 of the second wall section 101.

The

closure sections

104, 105 are pressed flat against one another by the first and

second closure elements

21, 20, so that the

closure sections

104, 105 formed by the inner layers 106 of the

walls

100, 101 bear against one another depending on the type of film and thus seal the hollow body 10. The closure composite 2V formed by the

closures

20, 21 is held in a defined closure position by the third closure 22, wherein folding of the

walls

100, 101 at 180 ° in the region between the

closure sections

104, 105 and the

sections

102, 103 offset transversely with respect to the

closure sections

104, 105 is caused, as can be seen in fig. 3C. This again improves the tightness of the closure device 2 in the closed position.

The first and

second blocking elements

21, 20 each have a

grip element

200, 210 on which a user can act. By acting on the blocking

elements

20, 21, the blocking

elements

20, 21 are released, in particular from the further third blocking element 22, and are set in the release position. In the release position, the blocking

elements

20, 21 can be separated from one another in an opening direction y, which is oriented perpendicular to the transverse direction x and the vertical direction z, in order to separate the

closure sections

104, 105 from one another, so that the interior of the hollow body 10 is accessible through the opening released thereby.

In the embodiment shown in fig. 4 to 6A-6C, the strip-shaped

bodies

202, 212, 222 are not made entirely of magnetic material, but rather have a system of receiving

openings

201, 211, 221, respectively, in which the individual magnetic elements of the respective

magnetic system

23, 24, 25 are received. The individual magnetic elements are arranged next to one another in the transverse direction X in this case so as to form a linear array of magnetic elements, wherein the

magnetic systems

23, 24, 25 of the

different closure elements

20, 21, 22 interact in a magnetically attractive manner in the closed position in order to sealingly close the hollow body 10 via the

closure sections

104, 105.

The individual magnetic elements of the

magnetic systems

23, 24, 25 can each be formed from individual permanent magnets, for example from neodymium material. However, it is also conceivable to realize that only one

magnetic system

23, 24, 25 or both

magnetic systems

23, 24, 25 have separate permanent magnets, while the other

magnetic systems

23, 24, 25 are formed by separate ferromagnetically acting elements.

Otherwise, the exemplary embodiment according to fig. 4 to 6A to 6C is functionally identical to the exemplary embodiment according to fig. 1 to 3A to 3C, in particular also in respect of the production of the part of the storage apparatus 1 which is made of a raw material containing the antimicrobial additive, so that in this respect reference should be made in full to the preceding statements.

The exemplary embodiment according to fig. 7 to 9A to 9C corresponds to the exemplary embodiment according to fig. 4 to 6A to 6C, wherein in this case, as in the exemplary embodiment according to fig. 4 to 6A to 6C, the third blocking element 22 is not present, so that the blocking device 2 is formed by only two blocking

elements

20, 21. The storage apparatus 1 has the same function as the storage apparatus 1 shown in fig. 4 to 6A to 6C.

Fig. 10A to 18B show an embodiment variant of the proposed solution, in which the locking device 2 is modified with a fastening mechanism S. The locking position of the locking composite 2V is additionally mechanically fastened via the fastening means S. The fastening means S are designed in particular to absorb shear forces (in the xz plane or in the vertical direction z, -z) and/or lifting forces (in the spatial direction y) which are caused by an increase in the internal pressure in the hollow body 10, for example by the liquid contained therein. Under the action of the shear forces, there is otherwise an increased risk that the closure composite 2V moves away from the third closure 22 and (upwards) flips into the release position about a spatial axis parallel to the x direction and additionally moves the two

closures

20 and 21 away from one another.

In the embodiment variant of fig. 10A and 10B, an additional fastening element in the form of a fastening web 3 is provided at the closure composite 2V. The fastening web 3 is fixed to the second closure part 20 and forms a carrier for the pair of first fastening parts 3.1, 3.2. The first fastening elements 3.1 and 3.2 protrude at the inner side 31 of the fastening web 3 by means of a fastening pin and are completely covered by the outer side 30 of the fastening web 3 in the closed position of the locking composite 2V.

If the locking composite 2V is turned into its locking position according to fig. 10B, the first fastening elements 3.1, 3.2 automatically lock into the second fastening elements 4.1 and 4.2 of the fastening device S, which are arranged at the wall section 100, in a form-fitting manner.

Engagement openings

41 and 42 are formed at the second fastening elements 4.1 and 4.2, which are arranged at a distance from the third blocking part 22 in the z direction and into which the fastening pins of the first fastening elements 3.1 and 3.2 are respectively locked. At the present time, a magnetic system is provided in each of the pair of first and second fastening elements 3.1/4.1, 3.2/4.2, so that when the first fastening element 3.1, 3.2 has come sufficiently close to the associated second fastening channel 4.1, 4.2 and thus sufficiently close to the fastening web 3 when the locking composite 2V is turned over, the first fastening element 3.1 or 3.2 is adjusted in a form-fitting locking position in each case magnetically supported manner at the respective second fastening element 4.1 or 4.2. The respective first fastening part 3.1, 3.2 is thereby moved into the normal locking position under the action of the respective magnetic system along the insertion slit 410 or 420, which is arranged at the

engagement opening

41, 42 of its associated second fastening part 4.1 or 4.2 and extends radially with respect to the

engagement opening

41 or 42. The pair of fastening elements 3.1/4.1, 3.2/4.2 thus each form a magnetically supported closure.

If the blocking composite 2V is present in the normal blocking position with respect to the third blocking element 22, additional fastening takes place via the fastening mechanism S of the blocking composite 2 and the fasteners 3.1/4.1, 3.2/4.2 engaging one another to prevent a reversal back into the release position. In order to release the fastening mechanism S, the fastening web 3 must be acted upon by the user with a release force F in a targeted manner _L Loaded to disengage the first and second fasteners 3.1/4.1, 3.2/4.2. The release force F must be applied here _L In order to transfer the first fastening elements 3.1, 3.2 fixed on the fastening web 3 out of the

engagement openings

41 and 42 of the associated wall-side second fastening elements 4.1 and 4.2 along the respective insertion slit 410 or 420. In the exemplary embodiment shown, the insertion slits 410 and 420 extend in the z direction in a parallel manner relative to one another, so that the release force F _L Must be applied to the fastening web 3 in the z-direction.

Alternatively, however, it is of course also possible to orient the insertion slits 410, 420 differently. In particular, it is conceivable that the

insertion slots

410, 420 are each open in the transverse direction x before the closure composite 2V is turned back so that a (complete) removal of the third closure element 22 becomes possible, so that the fastening web 3 must first be displaced transversely.

In the embodiment variant of fig. 11A and 11B, the fastening means S has two fastening elements in the form of narrow, strip-shaped fastening webs 223A, 22B, which are each arranged at the end of the longitudinal side of the third strip 222 of the third blocking element 22 via a

film hinge

222A or 222B. The

fastening webs

223A and 223B are thus placed at the strip 222 of the third closure member 22 via the

film hinge

222A or 222B, respectively.

In addition, additional fastening means of the fastening mechanism S in the form of

fastening pins

204A and 204B are formed on the second bar 202 of the second locking member 20. When the closure composite 2V is present in its closure position relative to the third closure part 22, the fastening pins 204A and 204B project in the y direction at the strip 202. At the

fastening webs

223A and 223B, in each case, a (shear force)

absorber

224A and 224B is formed in the form of a through-opening, which can be brought into positive engagement with the associated

fastening pin

204A or 204B by tilting the

fastening webs

223A and 223B about a hinge axis defined by the

respective film hinge

222A and 222B and running parallel to the z direction.

The fastening pins 204A and 204B are in this case each arranged at a distance from the longitudinal-side end of the strip 202, so that when the

receptacle

224A or 224B of the

fastening web

223A or 223B is engaged with the associated

fastening pin

204A or 204B, the fastening web always surrounds at least one end of the strip 202. The flat section of the

respective fastening web

223A or 223B is thus directly opposite the section of the strip 202.

In order to support a positive connection between the

fastening webs

223A, 223B of the third latch 22 and the second latch 20 of the latching composite 2V in the thus defined fastening position of the

fastening webs

223A, 223B and visible in fig. 11B, the magnetic system may be provided with

magnetic elements

205A, 205B at the fastening composite 2V and

magnetic elements

225A, 225B at the

fastening webs

223A, 223B. The

magnetic elements

205A, 205B of the closure composite 2V are arranged in fig. 11A, for example, on the second bar 202 of the second closure part 20 and interact here magnetically attractive with the

magnetic elements

225A and 225B of the

fastening web

223A or 223B. The

fastening webs

223A, 223B which support the turning in this way bear against the strip 202 and the respective strip-side fastening pins 204A, 204B engage in the web-

side receptacles

224A or 224B.

In the variant of fig. 11A and 11B, the closure composite 2V is also lifted off from the third closure 22 or the longitudinal ends of the strip of the

closures

20, 21, 22, in particular against the action of an increased internal pressure in the hollow body 10, via the

fastening webs

223A and 223B of the fastening mechanism S, which are each hinged on one side at the third closure 22, in order to counteract an undesired opening of the closure 2 in the event of filling of the cavity 10 with liquid. The embodiment variant of fig. 11A and 11B is therefore also particularly suitable for using the storage device 1 as a drinking water bag.

In the embodiment variants of fig. 12, 13 and 14, the locking device 2 is shown in a sectional view according to fig. 3C. In each of the embodiment variants shown in fig. 12, 13 and 14, the locking device 2 is reconfigured with an additional fastening means S. The fastening mechanism S, by means of a defined form fit, here between the composite closure element 2V and the third closure element 22, again counteracts a displacement of the composite closure element 2V in the closed position from the third closure element 22, in particular counteracting shearing of the third closure element 22 and, if appropriate, counteracting the separation of the two

closure layers

104 and 105 from one another. In this case, however, the fastening means S are each designed such that, when the liquid is to be filled into the hollow body 10 again, for example via the opening between the

closure sections

104 and 105, the closure composite 2V is released by a release force F in the spatial direction y _L The pulling-in is carried out, however in the unloaded state of the locking device 2, the locking composite 2V is easily removed by the user from the third locking element 22 and can be pivoted back (upward) into the release position.

In the embodiment variant of fig. 12, the fastening mechanism S has a first fastening element in the form of a fastening hook 216 at the first blocking element 21. In this case, in the closed position of the closure composite 2V, the fastening hook 216 projects in the direction y in the direction of the (first) wall 100 at the first closure part 21. For example, the fastening hooks 216 are formed for this purpose at the handle element 210.

In the closed position of the closure composite 2V, the fastening hook 216 lies opposite a fastening recess 226 of a second fastening element of the fastening mechanism S, which is formed by the third closure element 22. The fastening recess 226 is open in the z direction, so that the fastening hook 216, which projects in the y direction at the first blocking element 21, engages in a form-fitting manner with a hook end projecting in the z direction into the fastening recess 226 so that the third blocking element 22 can be partially engaged from behind.

In the closed position of the closing composite 2V, the fastening hook 216 is initially present in an intermediate position in which the fastening hook 216 (still) is not engaged with its hook end into the fastening recess 226. However, in the intermediate position, the fastening hook 216 lies opposite the fastening recess 226, so that due to the increased internal pressure in the hollow body 10 and the resulting pressure or shear force component F acting in the direction z on the closure composite 2V, a pressure or shear force component F acting in the direction z is produced _D In the event of a load on the closure device 2, the fastening hook 216 engages positively with the fastening recess 226. As a result, under the effect of the increased internal pressure, the fastening hook 216 is transferred into the engagement position, in which the fastening hook 216 engages behind the section of the second fastening element formed by the third blocking element 22 and blocks the blocking complex 2V against being removed from the third blocking element 22. Thereby, the blocking composite 2V is also blocked against overturning about a spatial axis parallel to the spatial direction-x (clockwise in fig. 12) into the release position.

In the modification of fig. 13, a positioning section 227 protruding in the y direction is provided at the wall 100 opposite the fastening clearance 226. The wall-side positioning portion 227 carries a magnetic element 227M which interacts magnetically attractive with the magnetic element 210M of the first locking part 21. The magnetic element 210M on the latch side is integrated here, for the present example, in the grip element 210. The normal positioning of the fastening hook 216 with respect to the fastening recess 226 can be ensured by means of the tilting of the closure composite 2V into its closure position via the magnetic attraction between the

magnetic elements

210M and 227M. It can thus be ensured in particular that the fastening hook 216 engages, as desired, into the engagement opening 2260 formed between the fastening recess 226 and the detent pin 227 by means of the tilting of the locking composite 2V into its locking position and is conventionally opposite the fastening recess 226, so that a form-fitting, blocking engagement of the fastening hook 216 into the fastening recess 226 is possible.

The occupation of the engagement position by the fastening hook 216 can also be supported via the

magnetic elements

227M and 210M. Thus, the

magnetic elements

227M and 210M can cooperate in such a way that the fastening hook 216 is automatically transferred from the intermediate position shown in fig. 13 into the engagement position or is supported at least once in a corresponding adjustment into the engagement position. If the fastening hook 216 is thus conventionally engaged into the engagement opening 2260 by means of turning the blocking complex 2V into the blocking position, the fastening hook 216 is driven further into the engagement position under the effect of the

magnetic elements

227M and 210M. In the engaged position, the fastening hook 216 then engages the third blocking element 22 from behind. In the fastening position thus defined, a positive-locking blocking engagement between the blocking composite and the third blocking element 22 is therefore already provided, which engagement is only established in the fastening position of the variant embodiment of fig. 12 by loading the blocking device 2.

In the embodiment variant of fig. 14, a fastening element in the form of a fastening tab 207 is provided as part of the fastening mechanism S at the closure composite 2V. The fastening tab 207 is formed on the second closing part 20 and projects from the second closing part 20 in the closing position of the closing composite 2V in the direction of the first wall 100 and thus in the direction of the y direction. The fastening tab 207 projects here as far as such that the end of the fastening tab 207, viewed in the z-direction, engages the third blocking element 22 from below or from behind. As a result, the locking composite 2V, which is fastened to the web 207 in the z direction so that it is in its locked position, does not move past the third locking element 22. Thus, the adjustment of the closure composite 2V in the z direction is mechanically prevented by the interaction of the fastening web 207 with the third closure element 22. As a result, the blocking composite 2V is thereby also prevented from moving away from the third blocking element 22 as a result of shear forces, for example due to increased internal pressure in the cavity 10. Thus, the fastening tab 207 must be adjusted in the y direction away from the wall 10 and thus also from the third closure element 22 by the targeted displacement of the closure composite 2V, so that the fastening tab 207 no longer prevents the closure composite 2V from being folded over.

Fig. 15 shows a front view of a further embodiment variant of the proposed storage device in the form of a water bladder 1 with an outlet 10A for connecting a water hose to the hollow body 10. Figure 15A shows a cross-sectional view of the hydration bladder 1 of figure 15. Fig. 16A to 16C, 17A to 17B and 18A to 18B show enlarged views of a further variant of the closure device 2, corresponding to detail C from fig. 15A.

In the variant of fig. 16A to 16C, analogously to the embodiment of fig. 13, the closure composite 2V is designed with an additional fastening member in the form of a fastening hook 206, which in the closed position of the closure composite 2V can engage in a form-fitting manner in a fastening recess 226 at the third closure 22 in order to additionally mechanically fasten the closed position of the closure composite 2V. In contrast to the exemplary embodiment of fig. 13, the fastening hook 206 is not formed here at the first closure part 21, but rather at the second closure part 20, here illustratively at the handle body 2000 of the handle element 200. In the embodiment variant of fig. 16A to 16C, the fastening hook 206 is thus formed in a projecting manner in the direction of the wall 100 at a second closing member which, in the closed position of the closure complex 2V, is in front of the first and

third closing members

21, 22, as viewed in direction-y (opposite to the opening direction y).

At the wall 100, an engagement opening 2260 for locking the fastening hook 206 on the composite side is newly defined between the strip 222 of the third locking element 22 and the positioning section 227 spaced apart from it in the vertical direction z. In order to facilitate the introduction of the fastening hook 206 into the engagement opening 2260, the handle body 2000 is hinged to the strip 202 of the second blocking element 20. For this purpose, the wall thickness in the transition section a between the strip 202 and the handle body 2000 connected thereto in the vertical direction z is reduced in a targeted manner and is visible as a recess in the cross-section of fig. 16A to 16C. In this way, a targeted elasticity is introduced between strip 202 and handle body 2000 at transition section a, so that handle 2000 can be moved relative to strip 202 on the user side about a hinge axis running parallel to transverse direction x. The handle body 200 can thus be connected to the strip 202, in particular via a film hinge defined by the transition section a.

By means of the transfer of the locking composite 2V into its locking position according to fig. 16A, the fastening hook 206 is introduced into the engagement opening 2260 and is initially present in the intermediate position according to fig. 16A. The

magnetic elements

227M and 200M, which act in an attractive manner with respect to one another, via the positioning section 227M and the handle body 2000 then displace the locking composite 2V in the vertical direction-z (upwards in fig. 16A to 16C) by means of the fastening hook 206. A transfer of the fastening hook 206 from the intermediate position into the engagement position is thereby effected, in which the fastening hook 206 engages in a form-fitting manner in the fastening recess 226 at the third blocking part 22.

In order to predetermine the engagement position between the fastening hook 206 on the closure composite side and the third closure part 22 and, if appropriate, additionally to fasten it, a positive connection between the handle body 2000 and the positioning section 27 is provided. A form-fitting element in the form of a latching projection 200R is thus formed at the handle body 2000 at a distance from the fastening hook 206. When the locking composite part 2V is transferred from the intermediate position into the engagement position by means of the fastening hook 206, the locking projection 200R snaps into a positive fit in the locking opening 227R at the positioning section 227 (see fig. 16B).

In order to release the fastening mechanism S and thus disengage the fastening hook 206 from the third latch 22 again, it is sufficient for the user to act on the handle element 200 and pivot the handle body 2000 outwards, i.e. away from the wall 100, about the hinge axis defined by the transition section a. The position of the hinge axis defined by the transition section a and the fastening recess 226 and the fastening hook 206 are coordinated with one another such that a corresponding pivoting movement of the fastening hook 206 is transferred away from the fastening recess 226 and the engagement opening 2260. In this way, a simple opening of the closure device 2 is made possible for the user, although the closure composite 2V is secured in various respects in the closed position against accidental opening and resists shear forces acting in particular in the xz plane and in the vertical direction z, which shear forces result from the increased internal pressure in the hollow body 10.

The embodiment variant of fig. 17A and 17B is in principle similar to the embodiment variant of fig. 16A to 16C. Unlike the embodiment variant of fig. 16A to 16C, in the embodiment variant of fig. 17A and 17B, the form fit is configured differently only in the engagement position between the handle body 2000 and the positioning section 227. Instead of the latching projections, latching tabs 200R which project in the cross section in the manner of a pin are therefore provided on the handle body 2000, which latching tabs can engage in corresponding latching openings 227R, which are formed, for example, in the manner of slits, on the positioning sections 227R.

In the embodiment variant of fig. 18A and 18B, a fastening mechanism S is provided, similar to the embodiment variant of fig. 16A to 16C and 17A to 17B, in which the closure complex 2V is transferred magnetically controlled with a fastener in the form of a fastening hook 216 from a first-occupied intermediate position into an engagement position in which the fastening hook 216 engages in a form-fitting manner in a fastening recess 226 at the third closure part 21. The fastening hook 216 is formed in the variant embodiment of fig. 18A to 18B on the first strip 212 of the first blocking element 21. The strip 212 then also interacts magnetically with the positioning section 227 in order to control the automatic transfer of the closure complex 2V into the engagement position. For this purpose, in the embodiment variant of fig. 18A-18B, at least one additional magnetic element 212M is arranged in the strip-shaped body 212 at a distance from the magnetic system 24 in the vertical direction z. The at least one additional magnetic element 212M of the first blocking member 21 interacts here, for example, with the at least one magnetic element 227M of the positioning section 27 in order to transfer the blocking composite 2V, which is turned toward the wall 100, from the first-assumed neutral position into the engaged position in the vertical direction z (upward).

In an alternative embodiment variant, it is of course also possible for the closure composite 2V to be folded or rolled up several times about an axis parallel to the transverse direction x in order to assume a closure position at the wall 100. Furthermore, it is not mandatory for the fastening of the locking position by means of the fastening mechanism S that the third locking part 22 interacts magnetically with the locking composite 2V. In particular in the embodiment variants of fig. 10A to 18B, the magnetic system 25 in the strip 222 of the third closure element 22 can therefore be dispensed with, without this impairing the function of the fastening mechanism S.

The concept based on the proposed solution is not limited to the embodiments described above, but can also be implemented in a completely different way.
