Definitions
- the present invention relates to a double-walled liquid container. This may in particular be a kettle.
- Liquid containers are known, inter alia, in the form of insulating containers in which a warm or cold beverage can be kept warm or cold for as long as possible. In order to improve the insulation properties, such liquid container are usually designed double-walled.
- Double-walled insulation containers are traditionally, as shown for example in DE 89 08 532, designed such that a continuous double-walled glass container is held in a surrounding jacket.
- the problem with these liquid containers is the fragility of glass and in particular of double-walled glass vessels.
- a liquid container in which a first container in the form of a glass body is inserted into a second container made of plastic. The two containers are held in a surrounding jacket container.
- liquid containers relate to kettles with an integrated heater and coffee pots for resting on hot plates.
- the bottom is contrary to the above Isolation containers usually designed such that it allows for the best possible heat conduction of the heat energy to the liquid for heating.
- the soil is therefore preferably formed single-walled in these liquid containers.
- These liquid containers also often have a double-walled side wall.
- a material such as glass or stainless steel is preferably used for the inner wall, which has advantageous properties for contact with food, but which is not suitable for the production of the outer structure of the liquid container.
- glass is ideal for food contact because it is odorless and easy to clean.
- glass as already mentioned, is fragile and less malleable than plastic.
- the inner wall is often kept in an outer covering structure, as for example in the kettle shown in EP 0 175 231.
- the liquid container is an insulation container.
- the inner wall is pressed by means of a screwed onto the shell lower part against an upper, attached to the casing seal member and is thereby fixed in the sheath.
- the outer structure takes in these double-walled liquid containers with single-walled in relation to the inner container so on the one hand a sheath function for protection or isolation purposes and on the other hand a holding function true. Due to the fact that the outer structure has to fulfill these two functions at the same time, however, there are conflicting requirements for their design, in particular with regard to the choice of material. A material which, for example, although good protective or insulating properties, but which is only poorly moldable and relatively brittle and therefore not to the perception of a holding function is suitable, therefore, can not be used for the outer structure.
- the present invention thus provides a double-walled liquid container having the following features:
- a support structure having an inner support member in which the upper edge of the inner side wall is held, and an outer support member in which the
- a fixing member attached to the support structure which fixes the lower edge of the outer side wall with respect to the support structure.
- the outer and preferably also the inner Sidewall fixed in the support structure By providing two side walls held in a support structure by means of a fixing member, there is provided a readily fabricated double-walled liquid container having an arbitrarily configured bottom in which the functions of holding and sheathing the inner side wall are structurally separated. While the outer side wall perceives the function of the casing, the holding structure serves in particular for holding the inner side wall.
- the outer side wall and the support structure may be made of different materials most suitable for the particular function.
- the holding structure which is usually best visible from the outside can also be designed in almost any desired manner and in particular also have openings, windows, etc.
- the support structure does not form a closed shell around the inner and outer side walls, the inner side wall is still protected from outside influences by the outer side wall.
- the inner side wall Due to the shape of the inner side wall, a longitudinal direction of the liquid container is defined.
- the inner side wall and particularly preferably the outer side wall is formed substantially cylindrical, whereby a radial direction of the liquid container is defined.
- the support structure usually extends along the longitudinal direction of the liquid container both downwards and upwards beyond the inner and outer side wall.
- the fixing element is then advantageously mounted below the inner and outer side wall on the support structure in such a way that the inner and outer side walls are fixed longitudinally in their position relative to the support structure and are thereby firmly held in the inner or outer support element of the support structure.
- the outer side wall may in particular also be clamped between the outer holding element of the holding structure and the fixing element.
- the inner side wall between the inner support member of the support structure and the fixing member may be clamped.
- the fixing element can exert a certain contact pressure on the lower edge of the outer side wall or the outer side wall.
- the inner side wall and the outer side wall are each transparent, and the support structure is preferably designed such that the interior is visible from the outside through the inner side wall and the outer side wall.
- the support structure advantageously has an upper base ring, on which the inner and the outer retaining element are arranged, and a lower base ring, on which the fixing element can be attached, wherein the two base rings are connected to each other by means of struts. Window openings are then present between the base rings and the struts through which the interior of the liquid container can be viewed.
- a handle may also be attached to the support structure, which may extend in particular from the upper base ring to the lower base ring.
- the inner side wall made of glass and the outer side wall made of a plastic such as polycarbonate (PC).
- PC polycarbonate
- the support structure of the inventive liquid container can be made of a different plastic, which is easier to mold compared to polycarbonate and a higher elasticity and thus better suited to the perception of the holding function.
- the inner side wall is formed closed downwards and thereby forms a bottom, which limits the interior downwards.

- this sealant may be an adhesive, such as Loctite TM.
- At least one support element is advantageously arranged between the inner side wall and the fixing element, which element is made of a substantially more flexible material compared to the inner side wall and the fixing element, so that it is suitable for compensating manufacturing tolerances with respect to the dimensioning of the length of the inner side wall.
- the support element which may in particular be made of silicone, is preferably attached to the fixing element.
- the support element is preferably designed as a support plug, which extends in the longitudinal direction of the liquid container through an opening formed on the fixing element and has a support surface facing the lower edge of the inner side wall.
