Definitions

  • the invention relates to a container for liquidy, pasty and/or solid materials, consisting of a base, a ring element and at least one opening and a membrane which forms an outer surface and is arranged between the base and the ring element.
  • the base and the ring element can be connected to each other, and an energy storing device is disposed between the base and the ring element.
  • containers for the storage and/or transport of liquid, pasty and/or solid materials.
  • Such containers which are called buckets for example, do however occupy a large storage space due to their outer dimensions and in dependence of their filling capacity.
  • containers which consist of a base and a membrane forming an outer surface and which have a carrying element, for example a carrying handle in the form of a section of an arc of a circle, attached to the membrane in order to carry said container.
  • a carrying element for example a carrying handle in the form of a section of an arc of a circle
  • containers for example drinking vessels, which consist of a base and ring element as well as additional ring elements provided between the said ring element and the base.
  • the diameter of the ring elements becomes increasingly smaller from the top ring element towards the base, and the ring elements are sealingly nested into each other, so that the container can be slid in a telescope fashion, in order to occupy little storage or transport volume when it is not used.
  • a disadvantage of this known container is that its design with serveral ring elements results in a high weight, and that for larger filling volumes and the associated pressures complicated sealings are additionally required between the ring elements, in order to provide a tight container.
  • This type of container is known from the document DE 42 43 678 A1 already mentioned above.
  • This document discloses a container for storing liquids and consisting of a lower and an upper border with an untearable PVC foil as well as a spiral spring arranged between said borders.
  • the upper border includes a screw-type closure that can be opened for filling liquids in or taking liquids out.
  • said preknown device includes a closure means which consists of hook members arranged for pivoting on the lower border and corresponding recesses provided on the upper border.
  • This preknown container for storing liquids can be compressed, and said spiral spring is bent by this compression.
  • a disadvantage of this preknown container resides in that the locking of the borders that are moved toward each other by means of pivotable hook members do not offer any sufficient safety against unintentional opening, so that the required connection between these two borders is not sufficiently stable if it is only one hook that is not correctly hooked in.
  • a further container is known from the document U.S. Pat. No. 2,886,084 disclosing a foldable, double-walled container.
  • This preknown prior art provides that the connection between the two elements which are made of a synthetic material and which are each arranged on the end side, can be effected by virtue of the flexibility of the synthetic material.
  • the invention is based on the problem of further developing a container in such a way that the container can be used as a supplementary multifunctional low-weight storage device which is particularly easy to handle.
  • the solution of this problem provides that the ring element can be twisted at least to a limited extent relative to the base around the longitudinal axis of the membrane, in order to open or close a bayonet-type closure which is disposed on the ring element and the base.
  • the container according to the invention includes a base, a membrane which forms an outer surface, and a ring element.
  • the membrane which is designed to be flexible is arranged between the ring element and the base and is urged via the linear motor, particularly the energy storing device into a stretched-out position.
  • the container In this initial position the container is suited not only for the transport of liquid, pasty and/or solid materials but also for storing these materials, since the base and the ring element are kept spaced from each other via the linear motor and the membrane is tensed.
  • a small transport and/or storage volume of this container is obtained by the ring element being urged against the action of the force of the linear motor in the direction of the base and being connected to the base upon reaching the same.
  • said ring element can grip over the base, in which case the membrane is arranged within the inner space of the ring element which is then left.
  • the energy storing device is formed as spiral spring, helical pressure spring or truncated cone spring, in the following referred to as “the spring” which is preferably arranged externally of the membrane and connected to the base and the ring element.
  • the spring can be manufactured easily and at low cost and can be readily connected to the base and the ring element, in order to form an inexpensive container.
  • the spring is connected to the ring element in such a way that the ring element can be twisted to a limited extent relative to the spring around the longitudinal axis of the membrane. So configured, the connection between the ring element and the base can be effected easily and safely by a bayonet-type closure in which the protrusions of the base or the ring element are pushed into corresponding recesses of the ring element or the base and thereafter the base is twisted with respect to the ring element, in order to lock the protrusions behind a projecting part adjacent to the recesses.
  • the spring is guided by its end facing the ring element in a groove which is formed in the ring element.
  • the spring is fixed to the base.
  • the spring which is formed as a spiral spring or helical pressure spring has at least one spiral turn and particularly 1.5 to 2 spiral turns, so that the space required for stowing the spring is very small when the container is folded.
  • the spring consists of a spring steel and can thus be manufactured in a simple and inexpensive way.
  • tempering steel or special steel is recommendable if the container will be used for liquids that lead to a fast corrosion of untempered steel.
  • the fixing of the guide channel to the membrane may be effected by a pasted joint.
  • the base consists of a ring and a metal core, with the membrane being fixed to the ring.
  • This two-part base has the advantage that through this metal core the container is for example suitable for heating a liquid, particularly water, over an open flame or on a different fire place like one that is electrically operated.
  • the metal core makes it possible that the heat is rapidly transmitted from the fire place to the medium to be heated, while the ring which preferably consists of a synthetic material reduces the weight of the container on one side and allows the membrane to be easily and sealingly fixed to the base on the other side.
  • the metal core includes a cavity wherein a burner element can be inserted.
  • the burner element can also be fixedly installed in the cavity.
  • the burner element is operated with gas, alcohol, diesel oil, kerosine and/or any other burning paste on the basis of these fuels.
  • a fuel can be arranged in an energy storage element which can be connected to the burner element.
  • cartouches which are clamped in a bracket that connects the cartouche to the burner element via a supply line.
  • drop-shaped elements filled with a burning paste can be inserted in the cavity. In this case, the burning pase is first ignited for heating the metal core which conveys the temperature for example to a liquid to be heated in the container.
  • the energy storage element is preferably exchangeably arranged in the cavity.
  • the metal core includes an opening with a sealing plate which closes the cavity.
  • the sealing plate can be formed as a perforated plate in order to guarantee sufficient oxygen supply for the combustion. If the sealing plate is formed as a closed plate the supply of energy will have to be provided in an other way, for example through openings in the metal core which connect the surroundings to the cavity.
  • the metal core is sealed in a manner such as to be movable with respect to the ring of the base at least in the radial direction. This makes sure that the metal core when heating can slide with respect to the ring, without any leakiness being caused.
  • the metal core includes a continuous peripheral, particularly radially open groove having the web-shaped ring arranged therein. Accordingly, the metal core grips over the ring.
  • the web-shaped ring has inside the groove a sealing ring on one side and a spring element on the opposite side.
  • the spring element is arranged between a wall of the groove of the metal core and the ring and therefore presses the ring in the axial direction of the container against the opposite wall of the groove, with the continuous sealing ring being disposed between this second mentioned wall and the ring.
  • the sealing ring is placed in a recess of the ring, in order to avoid a radial displacement of the ring.
  • the spring element is also formed in continuous fashion and is arranged in a recess of the ring.
  • thermal insulator which limits or inhibits any conveyance of the temperature generated within the metal core to the ring.
  • the thermal insulator is arranged between the metal core and the spring element.
  • the base includes an outlet valve that can be used for example for spending liquid contained in the container at a defined volume.
  • the membrane and the base or the ring of the base as well as the ring element are preferably made of a heat-resistant synthetic material, so that the same are resistant also in case of being heated over a fire place or by a heated liquid.
  • connection between the ring element and the base is preferably effected by the base having at least one and preferably more undercut recesses where at least one corresponding protrusion of the ring element can be locked in.
  • the recesses and/or protrusions are equally spaced around the periphery of the base and/or ring element, so that the base and the ring element are interconnected under equal forces over their whole peripheries.
  • the membrane is fixed to the ring element and/or base by one or two clamping rings.
  • the clamping ring(s) is(are) connected to the ring element and/or base by means of screws, with the membrane being arranged between the clamping ring and the ring member on one side and between the clamping ring and the base on the other side, respectively.
  • the clamping ring can be formed of at least two parts.
  • the ring element is formed with a U- or V-shaped cross-section.
  • the container has a round or oval cross-sectional shape.
  • a catching element may be provided which limits the distance between the ring element and the base, for example to protect the membrane against excessively high tensile forces.
  • the distance between the ring element and the base is set such that the membrane is stretched out and does not have any crinkles transversely to the axial direction of the container.
  • the catching element may consist particularly of ropes, preferably made of a synthetic material which is resistant to extension, such as carbon fibers for example, which are rubber coated.
  • the ropes are arranged between the membrane and the spring.

  • a container 1 for liquid, pasty and/or solid materials as shown in FIG. 1 consists of a base 2 , a ring element 3 arranged oppositely to the base 2 and including an opening 4 . Between the base 2 and the ring element 3 a membrane 5 is provided that forms an outer surface and that is made of a flexible soft synthetic material.
  • the base 2 is formed in two parts and has a core 6 of metal and a ring 7 of a heat-resistant synthetic material.
  • the ring 7 surrounds the core 6 .
  • the ring 7 In its external rim area the ring 7 has equally spaced protrusions 8 which are separated from each other by recesses 9 .
  • One end 10 of the membrane 5 rests on the ring 7 .
  • the end 10 of the membrane 5 is sealingly fixed to the ring 7 of the ring element 3 by means of a clamping ring 11 .
  • the clamping ring 11 is fixed to the ring 7 by means of screws 12 .
  • the end 10 of the membrane 5 rests exclusively on the ring 7 and is not in any contact with the core 6 of metal, so that at the use of the container 1 for heating a liquid such as water for example on a fire place the membrane 5 will not be heated directely through the core 6 .
  • the membrane 5 has in the central part thereof an energy storing device 13 formed as an elastic which constricts the membrane 5 in its central part.
  • an energy storing device 13 formed as an elastic which constricts the membrane 5 in its central part.
  • two or more energy storing devices may be provided, in order to pull the membrane into the interior of the container 1 , while the base and the ring element 3 are moved towards each other.
  • the energy storing device 13 is arranged within a guide channel 14 externally arranged on the membrane 5 and formed by a plastic strip 15 .
  • the plastic strip 15 consists of a material matching the material of the membrane 5 and is glued and/or welded to the membrane 5 .
  • the ring element 3 consisting of a synthetic material and shown in detail in FIG. 2 is substantially formed with a V-shaped cross-section and has on its outer leg 16 a web 18 aligned with an inner leg 17 .
  • a second end 19 of the membrane 5 is fixed by means of an additional clamping ring 20 that is fixed to the leg 17 of the ring element 3 by means of screws 21 .
  • the web 18 has on the free edge thereof plural recesses 22 that are equally spaced about the periphery of the ring element 3 .
  • the width of a recess 22 substantially corresponds to the width of a protrusion 8 of the base 2
  • the distance between two adjacent recesses 22 in the ring element 3 substantially corresponds in turn to the width of the recess 9 in the base 2 , so that the protrusions 8 of the base 2 can be passed through the recesses 22 and the parts arranged between the recesses 22 of the ring element 3 through the recesses 9 of the base 2 and so that the protrusions 8 , by slightly twisting the ring element 3 with respect to the base 2 , coming to rest in the area above the material between two adjacent recesses 22 of the ring element, so that the base 2 is connectible to the ring element 3 in the form of a bayonet-type closure.
  • a groove 23 is formed extending at least over a part-portion of the ring element 3 , in which groove one end 24 of a spiral spring 25 is guided, so that the ring element 3 is movable with respect to the end 24 of the spiral spring 25 .
  • the spring 25 surrounds the membrane 5 and is supported on and fixed to the base 2 by its second end. Through the spiral spring 5 the membrane is held in its stretched-out position when the base 2 and the ring element 3 are not locked, so that the container 1 is ready for being used to receive liquid, pasty and/or solid materials, according to its intended use. During this the spiral spring 25 develops a force which is orientated in the longitudinal direction of the container 1 and which is larger than the force provided by the energy storing device 13 , by which force the membrane 5 is constricted in the middle part thereof.
  • the force which is exerted for this purpose will be stored in the spiral spring 25 and at the same time the energy storing device 13 contracts the membrane in the middle part thereof, so that the membrane 5 cannot get into the connection area between the base 2 and the ring element 3 when the base 2 and the ring element 3 are brought together. Therefore, any damaging of the membrane 5 by structural components of the base 2 or the ring element 3 is almost impossible.
  • the container 1 which can be designed and used both as a bucket and a cooking pot or drinking vessel, assumes a relatively small transport volume, so that it can be used particularly for sports purposes like hiking, camping and water sport.
  • the selection of the materials, particularly of the synthetic material for the base 2 , the ring element 3 and the membrane 5 results in a very low weight, so that the container 1 according to the invention can be advantageously used in cases where it is important that the items which are carried along have the lowest possible weight.
  • mountaineering should be mentioned, where it is necessary to carry along a great number of items, but where the carrying capacity and the volume of corresponding pieces of luggage are very limited.
  • the above described embodiment of the container 1 according to the invention merely shows an advantageous example of execution.
  • the container 1 can deviate from the embodiment described in many respects, without leaving the scope of protection of the claims.
  • the connection between the base 2 and the ring element 3 can also be obtained by providing pin-like protrusions on the base 2 or the ring element 3 and by the respective one of the corresponding structural components, namely the ring element 3 or the base 2 having pivotable hook elements that surround the pin-like protrusions and fix the ring element 3 to the base 2 when the base 2 and the ring element 3 lie on top of each other.
