Abstract

The invention relates to a thermal insulation (1) for a drinks container, in particular for a drinks bottle for small children. Conventional thermal insulation for this purpose comprises a receptacle (2) for housing the drinks bottle and a lid (3). The disadvantage of said thermal insulation is that the lid (3) may not be connected to the receptacle (2) in a reproducible manner, which leads to poor insulation properties. Furthermore, and in particular there is the risk that the lid (3) is not tightly enough fastened to the receptacle (2) such that the lid (3) may unintentionally come free. According to the invention, in order to achieve a secure connection between receptacle (2) and lid (3) and improved and constant insulation values for the thermal insulation (1), the receptacle (2) and lid (3) may be connected to each other with a positive or positive and non-positive fit.

Description

DESCRIPTION

Thermal insulation for a beverage container, in particular for a drinking bottle for small children

The invention relates to a beverage container according to the preamble of claims 1 and 2. Such thermal insulation is described, for example, in DE-U-299 11 460.0.

State of the art

In the heat insulation according to DE-U 299 11 460.0, the relative position of the cover and the receptacle body of the heat insulation is fixed more or less indirectly, specifically via the drinking bottle shown there. The aforementioned fixation is achieved only by a certain clamping or friction of the inside of the lid of the thermal insulation on an upper region of the drinking bottle, for example on its cap covering the drinking teat, in the state of the lid placed on the drinking bottle located in 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 receptacle in relation to the outside atmosphere depends first and foremost on how well and safely the drinking bottle on the one hand with the receptacle body and on the other hand and in particular with the lid - is connected via the cap or the screw cap and / or also via the upper region of the cylindrical part of the drinking bottle - by clamping - that is to say non-positively.

Without a doubt, it is fundamentally possible, even under the circumstances and conditions described above, to achieve an acceptable tightness of the interior mentioned against the external atmosphere; however, this only if the dimensions of the elements involved (receptacle body, lid, drinking bottle and cap / screw cap) which are important for achieving such a function deviate from a respective ideal dimension within a relatively small tolerance. - Under these circumstances, it is in any case excluded that the tightness of the - in this case blunt - joint between the opposite wall parts of the receptacle body and lid, which is required for the best possible thermal insulation of the drinking bottle, is achieved when a tink bottle is accommodated in the thermal insulation should be, whose cylindrical part has a more or less below or also above the mentioned tolerance outer diameter and / or whose cap or screw closure is below or above the permitted tolerance. - As a supplement, it should be mentioned that the tolerances mentioned may be of the order of just a few tenths of a millimeter in order to ensure the desired functionality.

A further disadvantage of the known solution for thermal insulation for beverage containers described above is that there is no direct holding / locking connection between the lid and the receiving body, but rather only the above-mentioned indirect connection via the drinking bottle. This means that the hold of the lid in the desired position in contact with the receiving body is or may be more or less uncertain, depending on the particular circumstances with regard to the dimensions of the drinking bottle located in the receiving body which are essential for holding the lid.

Clamping the lid to the drinking bottle as described in the case of DE-U-299 11 460.0 has several disadvantages. On the one hand, the security of the attachment is dependent on narrow tolerances of the areas of the drinking bottle in question, so that certain variations in the diameter of the drinking bottle or dimensioning of these areas of the drinking bottle can lead to the lid either no longer being on the drinking bottle can be held or can not be attached to them at all. - Another disadvantage is that - even if the lid is held securely on or on the drinking bottle in some cases - due to a more or less wide remaining slit between the opposite ends of the receiving body and the lid, the possible insulating capacity of the overall arrangement of the receiving body / Drinking bottle / lid is significantly reduced. In addition, with such a solution there is also the risk that the lid can fall off the drinking bottle relatively easily as a result of an accidental contact, in particular when the lid is seated on / on the drinking bottle - because of tolerances in the diameter of the drinking bottle and / or other details important for the seat - is not optimal.

A design feature that is advantageous with regard to the daily use of the thermal insulation according to DE-U-299 11 460.0 is, however, the fact that the wall area delimiting the insertion and removal opening of the receiving body of the thermal insulation on two diametrically opposed wall sections is opposite the adjacent wall sections is designed to be retracted to a predetermined extent, so that gripping areas are formed for easy grasping and removal of the drinking bottle located in the receiving body.

DE-U-296 21 235.0 describes a foam-plastic, for receiving a beverage Can (so-called disposable can) provided thermal insulation, the lid of which can be clipped onto the receiving body receiving the beverage can. For this purpose, the drawing of this document shows a cone-like design of the respective one

Wall areas of the cover and receptacle body of the thermal insulation. - In contrast to the solution according to DE-U-299 11 460.0, in the case of DE-U-296 21 235.0 there is a direct connection between the cover and the receptacle body of the heat insulation, but this solution also adheres to the DE-U-299 above 11 460.0 described disadvantages with regard to the strength and safety of the seat / the connection between the cover and the receiving body, which is because of the not nearly exactly predictable - by the

Skill and the force required for attaching the lid to the receptacle dependent ^'- strength of each existing clamping action between the lid and receptacle body nor the difficulties come, giving rise to the assessable from a in their strength is not nearly exactly or predeterminable clamping connection. Ultimately, this also means an uncomfortable way of making or breaking up such a connection, since in particular with regard to the properties of foamed plastic, jerky, uncontrollable movements when making or breaking up such a connection must be expected.

Finally, on the market for the thermally insulating housing of a drinking bottle for toddlers, there are provided wrappings which are torn with a Closure are provided and which consist of an insert made of an open-pore foamed plastic ("foam") and a cover receiving this insert from a plastic film. These coverings are impractical to use and to a considerable extent have leaks in the interior housing the drinking bottle, which greatly reduce the desired insulating capacity of such a cover. A satisfactory insulation which approximately maintains the temperature of a beverage in the drinking bottle over a longer period of time - for example a period of two hours - cannot be achieved with this covering.

Aim.

Against the background of the described disadvantages of the thermal insulation of the type in question, the goal is pursued, based on the known solutions, of a reliable, at least approximately predeterminable to the extent of the connection or holding force achieved and of random factors such as, for example, the force expended by the user to create independent heat insulation when the cover is placed on the receptacle body, which moreover also ensures a satisfactory and constant good insulating ability of the heat insulation. solution

To achieve the objective outlined above, the solution specified in the characterizing part of claim 1 is proposed: the characterizing part of claim 2 names an alternative solution.

Advantageous or expedient further developments of the invention according to claims 1 and 2 are specified in claims 3 to 21.

benefits

With the present invention according to the independent claims 1 and 2, the aim is achieved to provide a consistently safe, practically independent connection between the cover and the receptacle body of the thermal insulation with consistently good and satisfactory insulating ability of the 'thermal insulation , which is also characterized by the fact that the forces to be used for establishing and releasing the connection can be predetermined relatively precisely or are predetermined by design and manufacturing features in the production of the thermal insulation.

A preferred embodiment of a thermal insulation according to the invention is specified in claim 3. In this embodiment, this occurs to a significant extent with certain foamed plastics existing, so-called resetting behavior is used to allow the positive or positive and non-positive connection between the cover and the receptacle to interact in the manner of a catch - i.e. a spring-loaded, positive or positive - and non-positive locking mechanism.

Another possible embodiment of a thermal insulation according to the invention calls claim 4. In contrast to the embodiment according to claim 3, the cover and / or the receiving body of the thermal insulation in the embodiment according to claim 4 are not in one piece, but - because of the additional locking elements to be introduced for the positive connection of the connection between cover and receptacle body - made of several parts. To this end, locking pins, wedges or the like which are fastened to the cover, are spring-loaded and can be actuated by hand from the outside of the cover and which engage in corresponding recesses or the like provided in the receiving body for the purpose of positive locking of the connection between the cover and the receiving body.

Claim 5 describes a further design feature which is advantageous with regard to the best possible insulating ability of the thermal insulation, the folds mentioned there preferably being provided several times - ie in the manner of a step fold - in the relevant wall areas of the cover and the receiving body. - Claim 6 gives a regarding the strength of the achievable connection between the cover and the receiving body, but also regarding the insulating ability further positive development of the mentioned folds.

The elements effecting the positive or the positive and non-positive connection between the cover and the receptacle can be provided continuously on the relevant wall areas of the cover and the receptacle. However, it is also possible and in the case of some connection solutions also expedient to provide the arrangement of these elements discontinuously, namely distributed over the circumference of the wall area in question, as proposed in claim 7. Claims 8 and 9 name particularly advantageous and preferred configurations in this connection.

Another possible embodiment of a positive and non-positive connection between the cover and the receiving body is specified in claim 10.

To achieve positive locking or positive and non-positive locking of the connection between the cover and the receptacle body of the thermal insulation, claims 11 to 13 name further possible designs.

In order to enable thermal insulation - or even just the heat-insulating receptacle or the lid containing a drinking bottle for small children - a stable position on a horizontal storage surface such as a table top, the receptacle and / or the lid must be covered with appropriate flattening as proposed in claim 14.

A further configuration of at least a substantial part of the outer wall of the cover and the receiving body serves to ensure good grip and thus also security in the daily use of the thermal insulation.

As a particularly advantageous and preferred material for the realization of the present invention for the production of the thermal insulation, closed-pore foamed polypropylene (EPP) is used in accordance with the proposal according to claim 16, in which, in addition, air has preferably been used as the expansion medium. In this way, with satisfactory heat insulation ability and very good rigidity and resistance of the structure, this becomes a pronounced, particularly advantageous one for the embodiment of the invention

Resilience behavior of the material achieved (desired locking effect of the preferably one-piece cover and receptacle!). In addition, such a material is special because of the use of air as an expansion medium when foaming the plastic for use in accommodating food and in connection with a food intake that takes place from such a container or in the immediate vicinity of such a container - Suitable dimensions. Claim 17 proposes the use of another material, namely paper mache or paper mache-like material for the production of the thermal insulation, to which claim '18 specifies an expedient addition.

A further embodiment which is advantageous and practical in certain embodiments of the thermal insulation according to the invention is claimed in claim 19; Claim 20 specifies a special embodiment of a joint in question there between the cover and the receiving body.

In view of the fact that a thermal insulation according to the invention for accommodating containers of different lengths / heights, in particular a drinking bottle for

Small children, which should be suitable for the lowest possible production outlay for the thermal insulation, finally proposes that the thermal insulation is accordingly designed as a set of components with elements that can be optionally plugged together for cover and receiving body.

1 to 11 show an inventive. Thermal insulation 1 or parts thereof, which thermal insulation 1 consists of a receptacle body 2 and a cover 3 which can be connected to the receptacle body 2. On the body 2 and the lid 3, when connected to one another - as is shown, for example, in FIG. 1 - form a casing for a known, not shown, drinking bottle for small children, as described, for example, in DE-U-299 11 mentioned at the beginning 460.0 is shown in connection with another thermal insulation. - While the receiving body 2 at least the major part of the lower, mostly cylindrical area of such a drinking bottle - preferably by means of ribs, not shown in detail and known per se in the drawing in the area of the inner wall of the receiving body, with a certain distance from the other areas of the inner wall of the receptacle body - holds, the upper part of the drinking bottle with the drinking teat, a cap for this or the like is covered by the lid 3.

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

The receptacle body 2 is closed except for an adjustment and removal opening 4. The lid opening, designated 5, of the lid 3 assigned to the receiving body 2, which is also designed to be closed except for the lid opening 5, is delimited by a wall area 6, the course and design of which are designated by 7, which delimit the insertion and removal opening 4 of the receiving body 2 Wall area corresponds. The wall area 7 delimiting the insertion and removal opening 4 of the receiving body 2 of the thermal insulation 1 is designed to be retracted to a predetermined extent on two diametrically opposed wall sections 8, 9 with respect to the adjacent wall sections 10, 11, so that gripping areas 12, 13 are easy Detect and remove the drinking bottle located in the receiving container 2.

On the inside of the wall sections 10, 11 there are grooves 14, 15, lying in a plane running transversely to the longitudinal axis of the receiving body 2 and cover 3, with ring sections 16, 17 of approximately the same shape in cross section in wall sections 18, 19 of the wall sections opposite these Cover 3 are assigned. The ring sections 16, 17 have a key-like

Function that can be seen in particular in the illustration in FIG. 7. - The one to the Wall sections 18, 19 adjoining, designated 20, 21, wall sections of the cover 3 are arcuate, for example approximately sinusoidal, and their course corresponds to the wall sections 8, 9 of the receiving body 2.

Furthermore, the wall areas 6, 7 of cover 3 or receiving body 2 have interlocking folds in the form of fold sections 22, 24, 26 and 28 of the

Cover 3, which correspond to the folded sections 23, 25, 27 and 29 of the receiving body 2 and which enable the thermal insulation to be particularly well insulated. The arrangement is such that the grooves 14, 15 and ring sections 16, 17 mentioned are integrated into the relevant folding sections.

The respective cooperating folds or fold sections can be designed such that in the closed state of the thermal insulation - that is, with the cover 3 placed on the receiving body 2 - in addition to the positive connection formed by the grooves 14, 15 and ring sections 16, 17 of receptacle body 2 and cover 3 also offer a non-positive connection of receptacle body 2 and cover 3. The execution as a rebate can also bring about further improvements in the insulating ability of the thermal insulation. For the purpose of connecting the cover 3 to the receptacle body 2, the cover 3 can be pressed onto the receptacle body 2 in the direction of the longitudinal axis of the cover 3 and the receptacle body 2 using a predetermined force, whereby the grooves 14, 15 or the ring sections 16, 17 having wall sections of the receiving body 2 or of the cover 3 temporarily bend to a certain extent - springing back into the starting position, but also the material of the cover 3 and the receiving body 2 in the area of mutual interaction during the connection process to a certain extent Pressure then evades and automatically "resets" after the connection has been made (utilizing the so-called resetting behavior of foamed plastic, in particular foamed polypropylene).

Another and particularly simple way of placing the lid 3 on the receptacle body 2 is to place the lid 2 with an annular section 16, 17 in the region of a groove 14, 15 of the receptacle body 2 obliquely on the latter and then to cover the lid 3 in the train a pivotal movement with the other ring section 16 or 17 in the other groove 14 or 15.

The above-mentioned behavior of the elements involved when the ring sections 16, 17 of the cover 3 are pressed into the grooves 14, 15 of the receiving body 2 represents the behavior of one of others because of the spring forces / restoring forces resulting from the properties of the material used Fields of technology known latching / latching, in which elements of the positive connection are combined with elements of the frictional connection.

FIG. 12 shows the connection area of a cover 30 to a receiving body 31 of another embodiment of a thermal insulation according to the invention, which is not shown in the rest. In this embodiment of the thermal insulation, the elements which bring about the positive or positive and non-positive connection between the receiving body 31 and the cover 30 are, on the one hand, a bead-like shape in the form of a so-called O-ring 32 or the like in the region of a fold 33 on the cover 30, on the other hand, a groove-like recess 34 corresponding to the O-ring 33 is assigned within a fold 35 of the receiving body 31.

The embodiment of the thermal insulation according to the invention according to FIG. 13, which is not shown in any further detail, shows a cover 36 which can be plugged onto a receiving body 37. The form-fitting, moreover optionally also non-positive connection of cover 36 and receptacle body 37 is served by an extension 38 of receptacle body 37 that widens towards the free end of the receptacle body and to which a correspondingly shaped annular recess 39 at the free end of cover 36 is assigned. In the case of this embodiment, too, the suspension properties or the mentioned resilience behavior of the material mentioned, which is preferably used for the production of the cover and the receiving body, become Achieving the desired secure positive locking, moreover possibly also a frictional connection of the connection of cover 36 and receiving body 37 is used.

14 shows a thermal insulation, the cover 40 or receiving body 41 - running parallel to the longitudinal axis of the cover 40 and receiving body 41 - has a flattened area 42. The flattening 42 serves to ensure a stable position of the thermal insulation or of the cover 40 and / or receiving body 41 on a horizontal storage surface such as e.g. to allow a table top.

15 shows a schematic representation of an embodiment of a further thermal insulation according to the invention with a cover 43 pivotably attached to a receiving body 42. The pivot connection can advantageously be made with one of the known, so-called film hinges, as indicated by reference number 44.

Fig. 16 shows a heat insulation, not shown, a cover 45, which can be positively and non-positively connected to a receptacle body 46 via a multi-thread thread similar to the known, so-called twist-off closure, consisting only of thread fragments , For this purpose, the cover 45 has 47 thread fragments 48 in the area of a fold, those in the area of a

Fold 49 of the receiving body 46 are associated with corresponding thread fragments 50. FIG. 17 shows a cover 51 of a heat insulation, which is not shown in any other way, and which is assigned by being placed on a receiving body 52. In the region of a fold 53 of the cover 51, bead-like formations 54 are provided for this purpose, which are also associated with ring-like formations 56 in the region of a fold 55 of the receiving body 52. When the cover 51 and the receiving body 52 are connected, the bead-like formations 54, 56 follow one another alternately; This means that the formations 54 and 56 of the cover 51 and the receiving body 52 form spaces between them which act like groove-like recesses for the other formations.

18 finally shows a portion of a cover 57 of a heat insulation, which is not shown in any further detail, and which — likewise only partially shown — is associated with a receiving body 58. While the cover 57 has, in the region of two successive folds 59, 60 (stepped fold), annular bead-like formations 61, 62, the folds 63, 64 of the receiving body 58 corresponding to these folds 59, 60 have corresponding ones corresponding to the formations 61 and 62, respectively groove-like recesses 65, 66. Also in the case of this embodiment of the invention, when the cover 57 is pushed onto the receiving body 58, the suspension behavior or resetting behavior of the material preferably used is used to achieve the desired To achieve positive locking and, if necessary, also non-positive locking (between the abutting surface areas of the folds 59, 60 on the one hand and 63, 64 on the other hand). It should also be mentioned that the wall of the folds 59, 60 and 63, 64 extends at a certain angle in the order of, for example, 7 ° to the longitudinal axis of the cover 57 and the receiving body 58, so that - if desired - self-locking or clamping between the respective abutting surfaces of the mentioned

Folds can be achieved, which can be achieved by appropriate dimensioning of the adjacent elements involved in the connection.
