Description

The invention relates to a vessel for liquid, pasty and / or solid substances, consisting of a bottom element, a ring element with at least one opening and a lateral surface forming membrane which is arranged between the bottom element and the ring element, wherein the bottom element and the ring element with each other can be connected and between the bottom element and the ring member, a force accumulator is arranged, wherein the ring member is at least limited rotatable relative to the bottom member about the longitudinal axis of the membrane.

Various vessels are known from the prior art, which are suitable for the storage and / or transport of liquid, pasty and / or solid materials. Such vessels are referred to, for example, as pails, but due to their external dimensions, they occupy a large storage volume depending on their filling capacity. In addition, vessels are known, which consist of a bottom element and a lateral surface forming membrane, wherein on the membrane, a support member, for example, a circular arc portion-shaped trained carrying handle is arranged to carry the filled vessel. However, these vessels are not suitable for the storage of liquid, pasty and / or solid substances, because after stopping the vessel, the membrane does not have sufficient stability to maintain the cavity for the liquid, pasty and / or solid material. In addition, vessels, such as drinking vessels are known, which consist of a bottom element and a ring member and arranged between the ring member and the bottom element further ring elements, wherein the ring elements are formed starting from the upper ring element towards the bottom element with ever smaller diameter and sealingly arranged one inside the other, so that the vessel in the manner of a telescope is telescopically to take when not in use, a smaller storage or transport volume. Disadvantage of this prior art vessel is that the design with multiple ring elements leads to a high weight and that, moreover, for larger quantities and the associated pressures consuming seals between the ring elements are required to create a dense vessel.

Such a vessel is known from the above DE 42 43 678 A1 known. 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 coil spring is arranged. The upper enclosure has a screw cap that can be opened for filling or withdrawing liquids.

Moreover, this prior art device has a closure which consists of hook elements pivotally arranged on the lower rim and recesses correspondingly arranged on the upper rim. This prior art container for storing liquids is compressible, being compressed by the compression of the coil spring.

A disadvantage of this known container is that the locking of the mutually moved enclosure by means of pivoting hook elements provide sufficient security against unintentional opening, so that even with only one insufficient adhered hook element, the required connection between the two enclosures is not sufficiently stable.

Another container is out of the US 2,886,084 which discloses a collapsible, double-walled container. In this known prior art it is provided that the connection between the two existing plastic end-mounted elements can be made due to the flexibility of the plastic.

Starting from this prior art, the invention has the object of further developing a vessel such that it is additionally used and a low weight as a multifunctional stocker handled particularly easily.

The solution to this problem provides that a bayonet-type closure is arranged on the ring element and bottom element.

The vessel according to the invention thus has a bottom element, a membrane forming a lateral surface and a ring element, wherein the membrane, which is designed to be flexible, is arranged between the ring element and the bottom element and pressed into a stretched position via the energy store. In this initial position, the vessel is not only suitable for the transport of liquid, pasty and / or solid substances, but also for the storage of these substances, as are held on the energy storage bottom element and ring element at a distance and the membrane is stretched. A small transport and / or storage volume is achieved in the vessel in that the ring element is pressed against the force in the direction of the bottom element and connected upon reaching the bottom element with this. Preferably, for example, the ring element engage over the bottom element, wherein the membrane is then arranged in the remaining interior of the ring element.

According to a further feature of the invention, it is provided that the energy accumulator as a coil spring, helical compression spring or as a truncated cone spring, hereinafter referred to as spring, is formed, which is preferably arranged outside the membrane and connected to the bottom element and the ring member. Such a spring is produced in a simple and cost-effective manner and can be easily connected to the bottom element and the ring member to form a low-cost vessel.

It is further contemplated that the spring is connected to the ring member such that the ring member is at least limited rotatable relative to the spring about the longitudinal axis of the membrane. Thus configured, the connection between the ring element and the bottom element can be effected in a simple and secure manner by a bayonet-type closure, in which projections of the bottom element or the ring element are inserted into corresponding recesses of the ring element or bottom element and then the bottom element is rotated relative to the ring element, to lock the projections behind a projection area adjacent to the recesses.

In a preferred embodiment, it is provided that the spring is guided with its end facing the ring element in a groove formed in the ring element. In this embodiment, prevents the spring during rotation of the ring member relative to the bottom element builds up a restoring force, which then rotates the ring member back to the starting position, whereby the connection between the ring element and bottom element lifted and the vessel is transferred from its collapsed position to the unfolded position ,

According to a further feature of the invention it is provided that the spring is fixed to the bottom element. But it is also possible to guide the spring on the bottom element in a groove relatively movable to the bottom element, while the spring is fixed to the ring member. It is essential here only that the bottom element is rotatable relative to the ring member about the longitudinal axis of the vessel, so that the spring is not subjected to torsional force.

Preferably, the spring formed as a spiral spring or helical compression spring has at least one spiral passage, in particular 1.5 to 2 spiral turns, so that the storage space necessary for the spring is very small when the vessel is folded.

The spring consists in particular of a spring steel and is therefore produced in a simple and cost-effective manner. If necessary, the use of tempered steel or stainless steel is recommended, as long as the vessel is used for fluids that cause rapid corrosion of un-tempered steel.

The membrane is formed of a heat-resistant, acid-resistant, liquid-tight, permeable, tear-resistant foil of a soft plastic, depending on the intended use of the vessel. In the case of a permeable film, the advantage can be achieved that, for example, mixtures of solid, pasty and liquid constituents can be separated from one another in a simple manner.

According to a further feature of the invention, it is provided that the membrane has a force store acting at right angles to its longitudinal axis, which preferably constricts the membrane in the middle area. This energy storage causes the membrane in a collapse of the bottom element and the Ring element is pulled into the region of the opening of the ring element, so that even with incorrect handling, the membrane is not clamped between the bottom element and the ring member, which may possibly lead to damage or destruction of the membrane, so that the vessel then for the intended purpose is no longer operational. The energy accumulator may be formed, for example, as an elastic band. It has proved to be advantageous to arrange the energy accumulator in a guide channel, which is preferably arranged on the outside of the membrane. In particular, the guide channel consists of a material which conforms to the material of the membrane, consequently of a soft plastic, so as not to negatively influence the flexible properties of the membrane even in the region of the guide channel.

Due to the material matching the guide channel and the membrane, it is particularly advantageous according to a further feature that an attachment of the guide channel on the membrane by a splice is possible.

It is provided according to a further feature of the invention that the bottom element consists of a ring and a metal core, wherein the membrane is attached to the ring. This two-part bottom element has the advantage that the vessel via the metal core, for example, for heating a liquid, in particular water over an open flame or on another, for example, electrically operated fireplace is possible. The metal core allows this rapid heat transfer from the hearth to the medium to be heated, while the ring, which consists for example of plastic, on the one hand reduces the weight of the vessel and on the other hand allows a simple and tight attachment of the membrane to the bottom element.

The metal core preferably has a cavity into which a burner element can be inserted. This burner element can also be permanently installed in the cavity. Preferably, the burner element is operated with gas, spirit, diesel, petroleum and / or fuel paste based on these fuels. Such a fuel can be arranged in an energy store which can be connected to the burner element. For example, cartridge can be provided for this purpose, which are clamped in a holder, which the cartridge via a supply line connect to the burner element. Alternatively, cup-shaped elements may be inserted into the cavity with a fuel paste filling in the cavity. Here, the fuel paste is previously ignited to heat the metal core, which emits the temperature, for example, to a liquid to be heated in the container.

Preferably, the energy storage is arranged interchangeably in the cavity for this purpose. In order to facilitate the interchangeability of the energy storage is provided that the metal core has an opening with a closure plate which closes the cavity. The closure plate can be designed as a perforated plate in order to ensure adequate oxygenation for combustion. If the closure plate is formed closed, the supply of oxygen in another way, for example, through openings in the metal core, which connect the environment with the cavity.

According to a further feature of the invention it is provided that the metal core is sealed against the ring of the bottom element movable at least in the radial direction. This ensures that the metal core can move when heated relative to the ring, without causing a leak. Preferably, the metal core has a peripheral edge, in particular radially open groove in which the web-shaped ring is arranged. The metal core thus overlaps the ring.

The web-shaped ring has within the groove on a sealing ring on the one hand and opposite a spring element. The spring element is disposed between a wall of the groove of the metal core and the ring and thus pushes the ring in the axial direction of the container to the opposite wall of the groove, wherein between this second-mentioned wall and the ring of the circumferential sealing ring is arranged. Preferably, the sealing ring is inserted into a recess of the ring to avoid a radial displacement of the sealing ring. The spring element is also formed circumferentially and arranged in a recess of the ring.

Between the ring and the metal core, a thermal insulator is further provided, the transition of the temperature generated in the metal core to the ring limited or prohibited. The thermal insulator is arranged in particular between the metal core and the spring element.

It is provided according to a further feature of the invention that the bottom element has an outlet valve, which can be used for example to a volume defined discharge of the liquid disposed in the vessel.

Membrane and bottom element or ring of the bottom element and ring element are preferably formed of heat-resistant plastic, so that they are resistant even when heated over a hearth or by a heated liquid.

The connection between ring element and bottom element is preferably carried out in that the bottom element has at least one, preferably a plurality of undercut recesses into which at least one corresponding projection of the ring element can be latched.

In particular, it is provided that the recesses and / or projections are arranged at regular intervals around the circumference of the bottom element and / or the ring element, so that the bottom element and ring element are connected to each other over their entire circumference with uniform forces.

According to a further feature of the invention it is provided that the membrane is attached to the ring element and / or on the bottom element with one or two clamping rings. Preferably, the or the clamping rings are screwed to the ring member and / or the bottom element, wherein between the clamping ring and the ring member on the one hand and the clamping ring and the bottom member on the other hand, the membrane is arranged. In a correspondingly thick membrane with flexible properties, the membrane then forms its own seal against the bottom element or the ring element and the clamping rings.

In order to simplify the assembly, the clamping ring can be formed from at least two sections.

The ring element is formed according to a further feature in cross section U- or V-shaped. Finally, it is provided that the vessel has a round or oval configuration of its cross section.

In addition, a catch element may be provided which limits the distance between the ring element and the bottom element, for example, to protect the membrane from excessive tensile forces. The distance between the ring element and the bottom element is in this case set such that the membrane is stretched and has no folds transverse to the axial direction of the vessel. The catching element may in particular consist of ropes, preferably of tensile plastic, such as carbon fibers, which are coated with a rubber coating. Preferably, the ropes are arranged between the membrane and the spring.

a second embodiment of a vessel in a side view.

An Indian FIG. 1 illustrated vessel 1 for liquid, pasty and / or solid substances consists of a bottom element 2, a bottom element 2 of the oppositely arranged ring element 3, which has an opening 4. Between the bottom element 2 and the ring element 3, a, forming a lateral surface membrane 5 is arranged, wherein the membrane 5 consists of a flexible soft plastic.

The bottom element 2 is formed in two parts and has a core 6 made of metal and a ring 7 made of a heat-resistant plastic. The ring 7 surrounds the core 6.

In its outer edge region, the ring 7 at uniform intervals projections 8 which are separated by recesses 9 from each other.

On the ring 7 is an end 10 of the membrane 5. The end 10 of the diaphragm 5 is secured with a clamping ring 11 sealingly on the ring 7 of the ring member 3, wherein the clamping ring 11 is screwed by screws 12 to the ring 7.

The end 10 of the membrane 5 rests exclusively on the ring 7 and is not in contact with the core 6 made of metal, so that when using the vessel 1 for heating a liquid, such as water on a hearth, the membrane 5 is not directly on the Core 6 is heated.

The membrane 5 has in its central region designed as an elastic force accumulator 13 which constricts the membrane 5 in the central region, wherein depending on the length of the membrane 5, two or more energy storage 13 may be provided to move the membrane 5 in a successive of Floor element and the ring element 3 in the interior of the vessel 1 to draw.

The energy storage 13 is according to FIG. 4 arranged in a guide channel 14 which is arranged externally on the membrane 5 and formed by a plastic strip 15. The plastic strip 15 consists of a matching with the material of the membrane 5 material and is glued to the membrane 5 and / or welded.

The existing plastic ring element 3, which in FIG. 2 is shown in detail in cross section is substantially V-shaped and has on its outer leg 16 a directed to an inner leg 17 ridge 18. On the leg 17, a second end 19 of the membrane 5 is fastened with a further clamping ring 20, wherein the clamping ring 20 is screwed with screws 21 with the legs 17 of the ring element 3.

The web 18 has at its free edge on a plurality of recesses 22 which are arranged distributed at a uniform distance over the circumference of the ring member 3. The width of a recess 22 substantially corresponds to the width of a projection 8 of the bottom element 2, wherein the distance between two adjacent recesses 22 in the ring element 3 again substantially corresponds to the width of the recess 9 in the bottom element 2, so that the projections 8 of the bottom element 2 through the recesses 22 and arranged between the recesses 22 of the ring member 3 sections can be guided through the recesses 9 of the bottom element 2 and by a slight rotation of the ring member 3 relative to the bottom element 2, the projections 8 in the region above the material between adjacent recesses 22 of the ring element 3 come to rest, so that the bottom element 2 is connectable to the ring member 3 in the form of a bayonet closure.

On a side facing the leg 17 inner wall of the leg 16 a extending at least over a portion of the ring member 3 groove 23 is formed, in which one end 24 of a coil spring 25 is guided, so that the ring member 3 relative to the end 24 of the coil spring 25 is movable.

The coil spring 25 surrounds the membrane 5 and is supported and fixed with its second end to the bottom element 2. About the coil spring 25, the membrane 5 at not latched bottom element 2 and ring element 3 held in its extended position, so that the vessel 1 is intended to accommodate liquid, pasty and / or solid substances. The coil spring 25 in this case develops a force which is aligned in the longitudinal axis direction of the vessel 1 and which is greater than the force provided by the energy accumulator 13, with which the membrane 5 is constricted in its middle region.

If now the ring element 3 is moved in the direction of the bottom element 2, the force applied for this purpose is stored in the spiral spring 25 and at the same time the energy accumulator 13 pulls the membrane together in its middle region, so that the membrane 5 does not collide with the bottom element 2 and ring element 3 can get into the connection area between bottom element 2 and ring element 3. Damage to the membrane 5 by the construction elements of the bottom element 2 and the ring element 3 is therefore almost impossible.

Reached the ring member 3, the bottom member 2 and engage the projections 8 through the recesses 22, the ring member 3 is rotated relative to the bottom member 2, whereby the end 24 of the coil spring 25 moves along the groove 23 and the ring member 3 is latched to the bottom member 2. In this position, the vessel 1, which can be designed and used both as a bucket, but also as a cooking vessel or drinking vessel, a very small transport volume, so that it can be used, for example, especially for sports purposes, such as hiking, camping or water sports can. The choice of materials, in particular of the plastic for the bottom element 2, the ring element 3 and the membrane 5 lead to a very low weight, so that the vessel 1 according to the invention can be used advantageously when it comes to carrying as low-weight equipment arrives. It may be mentioned at this point, for example, mountain sports, in which a variety of commodities are to take with you and the carrying capacity and the volume of appropriate luggage is very limited.

The above-described embodiment of the vessel 1 according to the invention shows only one advantageous embodiment. The vessel 1 may differ in many respects from the described embodiment without thereby the scope of the claims is abandoned. For example, the connection between the bottom element 2 and the ring element 3 can also be achieved by providing pin-shaped projections on the bottom element 2 or the ring element 3 and the respectively corresponding construction element, namely the ring element 3 or the bottom element 2 having pivotable hook elements when the floor element 2 and the ring element 3 lie on one another, surround the peg-shaped projections and fix the ring element 3 on the floor element 2. Such connecting elements may be arranged on the outside on the ring element 3 or bottom element 2. In addition, the vessel 1 may have a handle, not shown, which is preferably removably attached to the ring member 3.

Furthermore, it is possible to arrange a valve in the bottom element 2, which allows a defined outflow of a liquid substance arranged in the vessel 1.

FIG. 5 shows an alternative embodiment of the compound of the coil spring 25 with the ring member 3. The coil spring 25 is fixed with its end 24 to a sliding ring 26 which is rotatably mounted in a groove 27 of the ring member 3. The groove 27 is arranged between two webs of a cross-sectionally C-shaped profile section of the ring element 3. At this profile section is followed by an inwardly drawn portion of the ring member 3, to which the membrane 5 is fastened sealingly with its end outside.

In the FIGS. 6 and 7 the vessel 1 is shown in the pushed-together position. It is the bottom element 2 and that ring element 3 can be seen. The spring and the membrane are not shown for clarity. The bottom element 2 consists of the ring 7 and the metal core 6, which has a cavity 28 in which a burner element 29 is arranged. The metal core 6 is formed in two parts and consists of a lower part 30 with a cavity 28 substantially forming cup-shaped receptacle 31. Further, the metal core 6 has an upper, plate-shaped part 32 which is connected by screws 33 to the lower part 30 ,

The two parts 30 and 32 are formed round, wherein the lower part 30 has a circumferential and web-shaped portion 34 which is spaced from the upper part 32 mounted therefrom and forms with this a groove 35 for receiving the ring 7.

The burner element 29 can be operated with gas, alcohol, diesel, kerosene and / or a fuel paste based on these fuels, wherein the burner element 29 is arranged to be connectable or replaceable in the cavity 28 to an energy store, for example a gas cartridge.

The metal core 6 is arranged and sealed relative to the ring 7 of the bottom element 2 in the radial direction and sealed. For this purpose, the metal core 6 on the circumferential, radially open groove 35, in which the web-shaped ring 7 is arranged. The web-shaped ring 7 has within the groove 23 a sealing ring 36 on the one hand and on the opposite side a spring element 37. Further, a thermal insulator 38 is disposed between the ring 7 and the metal core 6.

The sealing ring 36 is round in cross-section and is located in a semi-circular cross-section annular groove which is circumferentially arranged in the upper part 32 facing surface of the ring 7. In the opposite surface of the ring 7, a circumferential recess 39 is arranged with a rectangular cross section, which serves to receive the thermal insulator 39 and the spring element 37.

The spring element 37 holds the portion 34 at a distance from the ring and thus the upper part 32 sealingly on the sealing ring 36. By this embodiment, the bottom element 2 is sealed even when using the vessel 1 as a saucepan. At the same time, this embodiment allows a relative movement of the metal core 6 to the ring 7, whose engaging in the groove 35 areas do not reach the groove bottom. An expansion of the metal core 6 during operation of the burner element 29 is therefore not contrary to the ring 7. The arrangement of the sealing ring 36 in the annular groove of this is fixed at radially occurring forces, so that the vessel remains tight even with repeated heating and cooling.

Finally shows FIG. 8 an alternative embodiment of a vessel 1, in which the coil spring 25 has been replaced by a truncated cone spring 40.
