Drink Bladder With Magnetic Closure Device

A drink bladder, comprising a hollow body for receiving a liquid, wherein

• the hollow body has at least one flexible wall and at least one port for connection to a drinking tube,
• the liquid can be filled into the hollow body via an opening that is formed between a first closing portion and a second closing portion and can be closed by a closure device of the drink bladder,
• the closure device includes a first closure part on the first closing portion and a second closure part on the second closing portion,
• the first closure part has a first strip body longitudinally extended along a transverse direction,
• the second closure part has a second strip body longitudinally extended along the transverse direction,
• the first closure part and the second closure part cooperate in a magnetically attracting manner in such a way that in a closed position of the closure device the first closing portion and the second closing portion rest against each other and form a closure compound with the first and second closure parts,
• the closure compound can be adjusted from a release position, in which the first and second closing portions can be properly separated from each other against a magnetic force applied by the first and second closure parts to clear the opening, by folding or rolling the first and second closing portions at least once into a sealing position, and
• the closure compound disposed in its sealing position is secured via a securing mechanism.
