DESCRIPTION OF THE INVENTION

[0064] FIGS. 1 to 3C show views of a first exemplary embodiment of a storage device 1 which has a storage body 10 that is formed by walls 100, 101 and is designed to hold a liquid, a gas or an item, in particular an electronic item such as a mobile phone or another item of daily life, for example a purse or a means of payment.

[0065] The walls 100, 101 are connected to each other for example by welding on parallel lateral edges spaced apart from each other along a transverse direction X and on a lower edge along a vertical direction Z and are to be closed by a closure device 2 in the region of an upper end such that an inner volume of the storage body 10 is sealingly closed in a closed position of the storage device 1 and an item received therein thus is protected against external influences, in particular moisture and dirt.

[0066] The walls 100, 101 are of flexible design so that the storage body 10 is flexibly deformable, in particular in order to be able to flexibly receive an item therein.

[0067] As can be taken from the sectional view of FIG. 3C, each wall 100, 101 is formed by two layers 106, 107, of which an inner layer 106 points towards the inner volume of the storage body 10 and an outer layer 107 points towards the outside.

[0068] The closure device 2 includes three closure parts 20, 21, 22.

[0069] Of these closure parts 20, 21, 22 a first closure part 21 is arranged on a closing portion 104 of the first wall 100, while a second closure part 20 is arranged on a closing portion 105 of the second wall 101 in such a way that the closure parts 20, 21 extend along the vertical direction Z at the same height on the respectively associated wall 100, 101. The closure parts 20, 21 cooperate in a magnetically attracting manner so that in the closed position of the storage device 1 the closing portions 104, 105, which are each formed by the inner layer 106 of the associated wall 100, 101, flatly and thus sealingly rest against each other.

[0070] A third closure part 22 is arranged on a portion 102 of the first wall 100 which is offset from the closing portion 104 of the first wall 100 and, as seen along a path of extension proceeding from the closing portion 104 in a cross-section as shown in FIG. 3C, arranged transversely offset from the first closure part 21.

[0071] The closure parts 20, 21, 22 each have a strip body 202, 212, 222 that is elongate along the transverse direction X and thus extends transversely to the vertical direction Z.

[0072] The closure parts 20, 21, 22 are designed to cooperate in a magnetically attracting manner. In the illustrated exemplary embodiment, the strip bodies 202, 212, 222 are each formed from a magnetically acting material, for example in that the strip bodies 202, 212, 222 are made of a plastic material or a silicone material into which magnetically active particles are embedded.

[0073] The strip bodies 202, 212, 222 can each act as permanent magnets and then face each other in pairs with unlike poles in such a way that in the sequence shown in FIG. 3C the strip bodies 202, 212, 222 magnetically attract each other. Alternatively, for example, merely the strip body 212 of the first closure part 21 can act as a permanent magnet, while the other strip bodies 202, 222 are of the ferromagnetic type so that the associated closure parts 20, 22 act as a magnetic armature. It is also conceivable, for example, that the closure parts 20, 21 are designed to be permanently magnetic at their strip bodies 202, 212, while the strip body 222 of the third closure part 22 acts ferromagnetically.

[0074] As can be taken for example from FIG. 3C, the strip bodies 202, 212, 222 are enclosed between the inner layer 106 and the outer layer 107 of the respectively associated wall 100, 101. The strip bodies 212, 222 of the closure parts 21, 22 are enclosed between the inner layer 106 and the outer layer 107 of the first wall 100, while the strip body 202 of the closure part 20 is enclosed between the inner layer 106 and the outer layer 107 of the second wall 101.

[0075] The closing portions 104, 105 are urged into flat contact with each other by the first closure part 21 and the second closure part 20 in such a way that the closing portions 104, 105 formed by the inner layers 106 of the walls 100, 101 rest against each other in the manner of membranes and thus sealingly close the storage body 10. The closure parts 20, 21 are held in a defined position by the third closure part 22, wherein a 180° convolution of the walls 100, 101 in a region between the closing portions 104, 105 and portions 102, 103 transversely offset from the closing portions 104, 105 is effected, as this can be taken from FIG. 3C. This further improves the tightness of the closure device 2 in the closed position.

[0076] The first closure part 21 and the second closure part 20 each include a handle element 200, 210 which can be grasped by a user. By action on the closure parts 20, 21 the closure parts 20, 21 can be released in particular from the further, third closure part 22 and be moved away from each other along an opening direction Y, which is directed perpendicularly to the transverse direction X and to the vertical direction Z, so that access to the interior of the storage body 10 is possible.

[0077] In the illustrated exemplary embodiment at least parts of the storage device 1 are fabricated from an antimicrobially active material or are provided with an antimicrobially active coating. The material consists of a composition which contains an antimicrobially active additive, for example silver-based, zinc-based, copper-based, cobalt-based, cadmium-based particles, particles based on titanium dioxide or particles based on an organic compound. In one embodiment, the antimicrobially active material is a material which contains a photocatalyst generating singlet oxygen (in-situ) when exposed to light. For example, the antimicrobially active material is a material which contains Dyphox®. The material can be used for manufacturing parts of the storage device as such, but can also serve to produce a coating on one or several parts.

[0078] For example, the walls 100, 101 can wholly or partly be fabricated from such a material. For example, the inner layer 106 and/or the outer layer 107 of each wall 100, 101 can be fabricated from such a material. For example, when the inner layer 106 of one or both walls 100, 101 is fabricated from a material containing an antimicrobially active additive, the storage device 1 has an antimicrobial effect on items received in the storage body 10. When the outer layer 107 additionally or alternatively is fabricated from a material containing an antimicrobially active additive, the storage device 1 has an antimicrobial effect on its outer surfaces.

[0079] The material of the inner layer 106 and of the outer layer 107 here can be the same or different.

[0080] Additionally or alternatively, the strip bodies 202, 212, 222 can also be fabricated from an antimicrobially active material.

[0081] In an exemplary embodiment shown in FIGS. 4 to 6C, the strip bodies 202, 212, 222 are not entirely fabricated from a magnetic material, but each include an arrangement of receiving openings 201, 211, 221 in which discrete magnetic elements of one magnet arrangement 23, 24, 25 each are received. The discrete magnetic elements are lined up one beside the other along the transverse direction X and thus form a linear array of magnetic elements, wherein in the closed position the magnet arrangements 23, 24, 25 of the different closure parts 20, 21, 22 cooperate in a magnetically attracting manner and thus sealingly close the storage body 10 via the closing portions 104, 105.

[0082] The discrete magnetic elements of the magnet arrangements 23, 24, 25 can each be formed by discrete permanent magnets, for example from a neodymium material. It is also conceivable, however, that merely one magnet arrangement 23, 24, 25 or two of the magnet arrangements 23, 24, 25 include discrete permanent magnets, while the other magnet arrangements 23, 24, 25 are formed of discrete ferromagnetically active elements.

[0083] Otherwise, the exemplary embodiment of FIGS. 4 to 6C is functionally equivalent to the exemplary embodiment of FIGS. 1 to 3C, in particular also with regard to the manufacture of parts of the storage device 1 from a material containing an antimicrobially active additive so that in this respect reference fully is to be made to the preceding explanations.

[0084] The exemplary embodiment of FIGS. 7 to 9C corresponds to the exemplary embodiment of FIGS. 4 to 6C, wherein in this case there is no third closure part 22, like in the exemplary embodiment of FIGS. 4 to 6C, and the closure device 2 thus is formed by merely two closure parts 20, 21. Otherwise, the storage device 1 is functionally equivalent to the storage device 1 of FIGS. 4 to 6C.

[0085] The idea underlying the solution is not limited to the exemplary embodiments described above, but can also be realized in an entirely different way.

[0086] In particular, for example materials with an antimicrobially active additive, which in particular have an antibacterial and antiviral effect, other than the materials mentioned here are also conceivable and possible.
