Definitions

• the invention relates to a vessel for liquid, pasty and / or solid substances, consisting of a base element, a ring element and at least one opening and a membrane forming a lateral surface, which is arranged between the base element and the ring element, the base element and the ring element together are connectable and an energy store is arranged between the base element and the ring element.
• vessels are known from the prior art which are suitable for storing and / or transporting liquid, pasty and / or solid substances. Such vessels are referred to as buckets, for example, but because of their outer dimensions they require a large storage volume depending on their filling capacity.
• vessels are known which consist of a base element and a membrane forming a lateral surface, a support element, for example a support handle designed in the form of an arcuate section, being arranged on the membrane in order to carry the filled vessel.
• a support element for example a support handle designed in the form of an arcuate section, being arranged on the membrane in order to carry the filled vessel.
• these vessels are not suitable for storing liquid, pasty and / or solid substances, since after the vessel has been switched off the membrane does not have sufficient stability to maintain the cavity for the liquid, pasty and / or solid substance.
• vessels for example drinking vessels
• vessels which consist of a bottom element and a ring element and further ring elements arranged between the ring element and the bottom element, the ring elements starting from the top ring element towards the bottom element being formed with an ever smaller diameter and arranged in a sealed manner, so that the container can be pushed into one another like a telescope so that it takes up less storage or transport volume when not in use.
• the disadvantage of this previously known vessel is that the design with a plurality of ring elements leads to a high weight and that, in the case of larger filling quantities and the pressures associated therewith, complex seals between the ring elements are required in order to create a tight vessel.
• Such a vessel is known from DE 4243 678 A1 already mentioned above.
• This document discloses a container for storing liquids, which consists of a lower and an upper enclosure, between which a tear-resistant PVC film and a spiral spring is arranged.
• the upper bezel has a screw cap that can be opened for filling or removing liquids.
• this previously known device has a closure, which consists of hook elements pivotably arranged on the lower frame and correspondingly arranged recesses on the upper frame.
• This previously known container for the storage of liquids can be compressed, the coil spring being tensioned by the compression.
• a disadvantage of this previously known container is that the locking of the bezel that is moved towards one another by means of pivotable hook elements does not offer sufficient security against unintentional opening, so that the required connection between the two bezels is not sufficiently stable even with only an insufficiently hooked hook element.
• the invention is based on the further development of a vessel in such a way that it can additionally be used as a multifunctional storage device with a low weight and, in particular, can be handled in a simple manner.
• the solution to this problem provides that the ring element can be rotated at least to a limited extent relative to the base element about the longitudinal axis of the membrane in order to open or close a bayonet-type closure on the ring element and base element.
• the vessel according to the invention thus has a base element, a membrane forming a lateral surface and a ring element, the membrane, which is of flexible design, being arranged between the ring element and the base element and being pressed into an extended position by the linear motor, in particular the energy accumulator.
• the vessel is not only suitable for the transport of liquid, pasty and / or solid substances, but also for the storage of these substances, since the linear element keeps the base element and ring element at a distance and the membrane is stretched.
• a low transport and / or storage volume is achieved in the vessel by pressing the ring element against the force of the linear motor in the direction of the base element and connecting it to the base element when it reaches it.
• the ring element can preferably overlap the base element, the membrane then being arranged in the remaining interior of the ring element.
• the energy accumulator is designed as a spiral spring, helical compression spring or as a truncated cone spring, hereinafter referred to as a spring, which is preferably arranged outside the membrane and is connected to the base element and the ring element.
• a spring can be produced in a simple and cost-effective manner and can be connected to the base element and the ring element without any problems in order to form an inexpensive vessel.
• the spring is connected to the ring element in such a way that the ring element can be rotated at least to a limited extent relative to the spring about the longitudinal axis of the membrane.
• the connection between the ring element and the base element can be made in a simple and secure manner by a bayonet-type closure, in which projections of the base element or the ring element are inserted into corresponding recesses in the ring element or base element and the base element is then rotated relative to the ring element, in order to lock the projections behind a projection region adjacent to the recesses.
• the spring with its end facing the ring element is guided in a groove formed in the ring element.
• This configuration prevents the spring from building up a restoring force when the ring element is rotated relative to the base element, which then rotates the ring element back into the starting position, whereby the connection between the ring element and base element is released and the vessel is moved from its collapsed position to the opened position ,
• the spring is attached to the base element.
• the base element can be rotated relative to the ring element about the longitudinal axis of the vessel, so that the spring is not subjected to any torsional force.
• the spring designed as a spiral spring or helical compression spring preferably has at least one spiral gear, in particular 1.5 to 2 spiral gears, so that the storage space required for the spring is very small when the vessel is folded.
• the spring consists in particular of spring steel and can therefore be manufactured in a simple and inexpensive manner. If necessary, the use of tempered steel or stainless steel is recommended, provided the vessel is used for liquids that lead to rapid corrosion of non-tempered steel.

• the metal core enables rapid heat transfer from the fireplace to the medium to be heated, while the ring, which is made, for example, of plastic, on the one hand reduces the weight of the vessel and on the other hand allows simple and tight attachment of the membrane to the base element.
