Description

The The invention relates to a thermal insulation for one Beverage containers, in particular for one Drinking bottle for Toddlers.

State of the art

The DE 299 11 460 U1 describes a heat insulation for a beverage container, in particular for a drinking bottle for toddlers, in the form of an existing at least substantially foamed plastic sheath for the beverage container, consisting of a closed up to a setting and removal opening in itself receiving body and the receiving body associated lid consists, the wall opening bounding the lid opening corresponds with the wall of the adjustment and removal opening of the receiving body limiting wall area. However, it is not apparent from this document how the respective wall areas of receiving body and lid should be formed in detail, so that it comes to a coherent connection, that is, to a possible airtight abutting the respective wall areas. In this respect, the statement that the relevant wall region of the cover "corresponds" to the respective wall region of the receiving body represents only a task for which the document does not disclose a solution. Analogously, the reference to a "conclusive" connection between the lid and the receiving body only has the quality of a task, without a solution would be disclosed in detail (see page 6, lines 23-29 of the document).

When the heat insulation after the DE 299 11 460 U1 A more or less good fixation of the relative position of the lid and the receiving body of the thermal insulation takes place indirectly, via the drinking bottle shown there. The mentioned fixation is achieved exclusively by a certain clamping or friction of the inside of the cover of the heat insulation at an upper region of the drinking bottle, eg at the cap covering the drinking teat, in the state of the lid attached to the drinking bottle located in the receiving body. Without taking into account the open, above-mentioned question of the exact design of the respective wall regions of the lid and the receiving body, this means that the quality of the air seal between the interior of the thermal insulation formed by the lid and the receiving body is initially and substantially dependent on the external atmosphere, how well and safely the bottle for a connection with the receiving body and the other and in particular with the lid - via the cap or the screw cap and / or over the upper portion of the cylindrical portion of the bottle - clamped, that is non-positively connected.

undoubtedly it is basically possible, too under the circumstances described above and conditions of an indirect connection of the lid and the receiving body acceptable tightness of the mentioned Interior opposite to achieve the external atmosphere; However, this only if the for achieving such a function important dimensions of the elements involved (receiving body, cover, Drinking bottle and cap / screw cap) within a relative only slight tolerance deviate from a respective ideal measure. - Under these circumstances it is excluded in any case, that for the sake of a best thermal insulation The water bottle required tightness of - here dull running - joint between the opposite ones Wall parts of receiving body and Lid is reached when a Tinkflasche in the heat insulation is to be housed, the cylindrical part of a more or less below or above the mentioned tolerance lying outer diameter has and / or their cap or screw below or above the approved tolerance. - Just additional be cited that mentioned Tolerances of the order of magnitude of only a few tenths of a millimeter may be to the desired mode of operation sure.

Further is disadvantageous in the above-described known solution for heat insulation for beverage containers, that there is no direct holding / locking connection between the lid and the receiving body, but only the above-mentioned indirect Connection via the drinking bottle. This means that the stop of the lid in the desired, the receiving body adjacent position is more or less uncertain or may be dependent of the particular circumstances with respect to the maintenance of the lid essential Dimensions of the receiving body located drinking bottle.

A clamped attachment of the lid to the bottle as in the case of DE 299 11 460 U1 So described has several disadvantages. Firstly, the safety of the attachment of tight tolerances of the relevant areas of the bottle is dependent, so that certain variations in the diameter of the bottle or dimensioning of these areas of the bottle can cause or cause the lid either can not be held on the bottle or not even be plugged on this. - Another disadvantage is that - even if in some cases, if possible satisfactory hold the lid on or on the bottle - because of a more or less wide remaining slot between the opposite ends of receiving body and lid the per se possible insulation of the overall arrangement receiving body / bottle / lid is significantly reduced. Moreover, in such a solution there is also the risk that the lid may fall off the drinking bottle relatively easily as a result of accidental contact, especially if the lid is seated on the drinking bottle - due to tolerances in the diameter of the drinking bottle and / or other for the seat of important details - not optimal.

As for the daily use of heat insulation after the DE 299 11 460 U1 advantageous design feature, however, is the fact that the adjustment and removal opening of the receiving body of the heat insulation limiting wall region is performed at two diametrically opposed wall sections relative to the adjacent wall sections to a predetermined extent, so that gripping areas for easy detection and removal of the receiving body are formed drinking bottle.

The DE 26 16 502 A1 describes an insulated container for bottles, which consists of an upper part and connectable to the upper part via a positive connection lower part. The upper part of the bottle enclosing upper part is provided with a through opening for the bottle mouthpiece and a releasable latching support for attachment to the lower part. As a latching support, the upper part is provided with abutting from its inner peripheral edge on the inner wall of the lower part tabs, which have on their outer side with corresponding recesses in the wall of the lower part corresponding projections. In this case, two such tabs are provided with latching projections in radially opposite position, which should have a size sufficient for finger operation. Moreover, the upper part of this insulating vessel is designed not only open to the lower part, but also has an opening at the opposite end of the lower part. Through this opening through the closure of the bottle, for example, a cork or a screw cap, so accessible from the outside. However, it can also be provided an interception plug for this region of the upper part, whose overlap connects to the shape of the insulating vessel.

To the isolation vessel after the DE 26 16 502 A1 is first to note that it is designed clamshell, namely consists of an outer shell and an inner insulating material. This type of execution of the isolation vessel is per se expensive and obviously not been introduced into the practice. In addition, it is unclear from which materials the insulated vessel should be made. This unanswered question is particularly important in view of the fact that the mentioned tabs of the upper part of the insulating vessel must have sufficient suspension behavior in order to meet the intended locking function can.

In addition, it is likely for a user of the isolation vessel after the DE 26 16 502 A1 be difficult and cumbersome at least, under the drawing to be taken constructive conditions to separate the two parts of the isolation vessel by finger operation from each other or to connect with each other. A simple operation in the sense of a simple connection and detachment of the two parts of the isolation vessel is certainly not possible in the case of this vessel.

Finally, the upper part of the insulating vessel after the DE 26 16 502 A1 a significant length in relation to the lower part, whereby after releasing from the lower part of a significant part of the temperature-wise insulated bottle is exposed. This does not serve a good and lasting as long as the temperature. This disadvantage is exacerbated by the fact that the upper part is made open at the top.

The US 31 20 319 A describes an intended for a bottle, consisting of a lid and a receiving body for the bottle existing insulating vessel, which is also designed clamshell. While the outer shell is preferably made of polystyrene, the inner shell should be made of compressible foam, preferably polyurethane foam. A bottle located in the receiving body should be held securely in this under a certain compression of the foam of the inner shell and associated friction inhibition between the bottle and inner shell. A disadvantage of this construction of the insulating vessel is that the inner shell - because of the required compressibility - must consist of open-cell foam. This type of foam has a very poor insulating power, so that the insulating capacity of the vessel after the US 31 20 319 A essentially depends on the insulating ability of the outer shell.

Due to the bivalve structure of the insulated vessel after the US 31 20 319 this is how the insulated vessel after the DE 26 16 502 A1 Costly to manufacture, which includes not only the use of different materials and their different manufacturing and processing, but also the need to properly fit the two shells of the insulated vessel together.

The connection of lid and receiving body takes place in the US 31 20 319 A by means of a kind Screw connection with short fragments of threads. In order to facilitate the relative rotational movement of both parts, which is to be carried out to one another or to connect or detach the lid and the receiving body, the lid of this insulating vessel has wing-like extensions at its upper, closed end. These extensions not only have a negative effect on the production costs of the insulated container, but are also at risk of breakage because of their exposed and fragile design.

The DE 296 21 235 U1 describes a made of foamed plastic, for receiving a beverage can (so-called disposable) provided heat insulation, the lid on the beverage can receiving female body is clamped attachable. For this purpose, the drawing of this document shows a respective cone-like design of the respective wall regions of the lid and receiving body of the heat insulation. - In contrast to the solution after the DE 299 11 460 U1 exists in the case of DE 296 21 235 U1 Although a direct connection between the lid and the body of the heat insulation, but also hard this solution already above DE 299 11 460 U1 described disadvantages with respect to the strength and safety of the seat / the connection between the lid and the receiving body, including because of the not nearly exactly predictable - dependent on the skill and the effort when attaching the lid on the receiving body - strength of each existing clamping action between the lid and receiving body still the difficulties come, which originate from an in its strength not nearly exactly predictable or predeterminable clamping connection. This ultimately also means a less convenient way of producing or dissolving such a compound, as in particular with regard to the properties of foamed plastic with jerky, uncontrollable movements in the manufacture or dissolution of such a connection must be expected.

Finally in the market for heat-insulating Provision of a drinking bottle for toddlers provided enclosures offered, which provided with a zipper are and are made of an insert of an open-celled foamed plastic ("Foam") and one of these Insert receiving cover consist of a plastic film. These wraps are impractical in the Use and show significant leaks of the bottle receiving interior, which is actually the intended good Insulating capacity such a cladding greatly reduce. A satisfactory, the temperature of one in the bottle beverage over a longer period - for example a period of two hours - approximately maintaining isolation is with this cladding impossible to achieve.

The 1 to 11 show a thermal insulation according to the invention 1 or parts of it, what heat insulation 1 from a receiving body 2 and one with the on take body 2 connectable lid 3 consists. receiving body 2 and lid 3 form in interconnected state - as he is for example in 1 is shown - a sheath for a known per se, not shown drinking bottle for toddlers, as shown for example in the above-mentioned DE-U-299 11 460.0 shown in conjunction with another heat insulation. - While the receiving body 2 at least the majority of the lower, mostly cylindrical region of such a bottle - preferably represented by in the drawing in the region of the inner wall of the receiving body, unspecified and known per se ribs with a certain distance from the remaining areas of the inner wall of the receiving body - receives , the upper part of the drinking bottle with the teat, a cap for this or the like. From the lid 3 covered.

The receiving body 2 and the lid 3 are each made in one piece of a foamed plastic, preferably from closed-pore, air-foamed polypropylene. The advantages of this material have already been mentioned.

The receiving body 2 is up to a setting and removal opening 4 closed executed. With 5 designated lid opening of the receiving body 2 assigned, except for the lid opening 5 also in self-contained lid 3 is from a wall area 6 limited, its course and design with the setting and removal opening 4 of the recording body 2 limiting, with 7 designated wall area corresponds. It is the setting and removal opening 4 of the recording body 2 the heat insulation 1 bounding wall area 7 at two diametrically opposite wall sections 8th . 9 opposite the adjacent wall sections 10 . 11 executed to a predetermined extent, so that gripping areas 12 . 13 for easy detection and removal of the in the receptacle 2 are formed drinking bottle.

On the inside of the wall sections 10 . 11 are located - in a direction transverse to the longitudinal axis of receiving body 2 and lid 3 extending plane lying - grooves 14 . 15 , which in cross-section approximately correspondingly shaped ring sections 16 . 17 in this Wandungsabschnitten opposite wall sections 18 . 19 of the lid 3 assigned. The ring sections 16 . 17 have a feather-like function, in particular the appearance in 7 can be seen easily recognizable. - The to the wall sections 18 . 19 subsequent, with 20 . 21 designated wall sections of the lid 3 are arcuate, for example, running approximately sinusoidally running and correspond with respect to their course with the Wandungsabschnitten 8th . 9 of the recording body 2 ,

Furthermore, the wall areas 6 . 7 from lid 3 or receiving body 2 interlocking folds on in the form of fold sections 22 . 24 . 26 and 28 of the lid 3 that with fold sections 23 . 25 . 27 respectively. 29 of the recording body 2 Correspond and allow a particularly good insulation of the heat insulation. The arrangement is such that the mentioned grooves 14 . 15 and ring sections 16 . 17 are integrated in the respective fold sections.

In this embodiment, the heat insulation are the form-fitting or positive and non-positive connection between the receiving body 31 and lid 30 effecting elements on the one hand a bead-like shape in the form of a so-called O-ring 32 or the like. In the area of a fold 33 on the lid 30 on the other hand one with the O-ring 33 corresponding groove-like appearance mung 34 within a fold 35 of the recording body 31 assigned.

The embodiment of the invention, not otherwise shown heat insulation after 13 shows a lid 36 standing on a receiving body 37 Aufsteck1ar is. The form-fitting, in addition, if necessary, in addition also non-positive connection of cover 36 and receiving body 37 serves a to the free end of the receiving body towards expanding extension 38 of the recording body 37 , Which a correspondingly shaped annular recess 39 at the free end of the lid 36 assigned. Also in the case of this embodiment, the suspension properties or the mentioned restoring behavior of said, preferably used for the production of lid and receiving body material to achieve the desired positive fit, in addition, possibly also a frictional connection of the cover 36 and receiving body 37 exploited.

14 shows a heat insulation, whose lid 40 or receiving body 41 - parallel to the longitudinal axis of the lid 40 and receiving body 41 running - a flattening 42 having. The flattening 42 serves to ensure a stable position of the heat insulation or of the lid 40 and / or receiving body 41 to allow on a horizontal shelf such as a table top.

15 shows a schematic representation of an embodiment of another heat insulation according to the invention with a on a receiving body 42 hinged lid 43 , The pivotal connection can be advantageously carried out with one of the known, so-called film hinges, as denoted by the reference numeral 44 is indicated.

16 shows from a not otherwise shown heat insulation a lid 45 that with a receiving body 46 about a known per se, so-called twist-off closure similar, multi-threaded, consisting only of thread fragments thread positively and non-positively connectable. For this purpose, the lid 45 in the area of a fold 47 thread fragments 48 on those in the area of a fold 49 of the recording body 46 Corresponding threaded fragments herewith 50 assigned.

In 17 is of a not otherwise shown heat insulation a lid 51 shown by attaching to a receiving body 52 assigned. In the area of a fold 53 of the lid 51 are annularly bead-like formations for this purpose 54 provided in the area of a fold 55 of the recording body 52 likewise annular circumferential bead-like formations 56 assigned. In the state of connection of cover 51 and receiving body 52 follow the bead-like formations 54 . 56 alternately on each other; that is, the formations 54 respectively. 56 of the lid 51 or the receiving body 52 form spaces between them, which act as groove-like recesses for the other forms.

18 Finally, from a heat insulation not shown otherwise shows a portion of a lid 57 , which - also shown only partially - a receiving body 58 assigned. While the lid 57 in the area of two successive folds 59 . 60 (Shiplap) annular annular bead-like formations 61 . 62 have, with the show those folds 59 . 60 corresponding folds 63 . 64 of the recording body 58 corresponding, with the formations 61 respectively. 62 corresponding groove-like recesses 65 . 66 on.
