Description

Stackable vessel with double and perfect area

The invention relates to a vessel, in particular a Getränkege ^¬ fäß, preferably of glass, which is double-walled in a lower, a voltage Publ ^¬ opposite region, and which has a single-walled area between the double-walled region and the opening.

Forming vessels double-walled for the purpose of thermal insulation has been known since the invention of the principle by James Dewar in 1874 and the application of a patent based thereon by Reinhold Burger in 1903 (DE 170057 C).

From this principle, starting the AT 9949 Ul shows a Portions ^¬ vessel for foodstuffs, which has a single-end edge at the top. The single-walled area serves drinking comfort. The vessels disclosed therein all have a stem-shaped portion, on which - similar to a wine glass - followed by a substantially plate-shaped foot for parking.

Furthermore, the US 6,419,108 Bl shows a thermally insulated Getränkege ^¬ fäß. The thermal insulation is an evacuated space between an outer and an inner wall. The inner wall protrudes above the height of the outer wall, and thus forms an upper einwan ^¬-ended range. The glass is substantially cylindrical so that the bottom circumference and opening circumference are substantially identical.

The vessel shown in WO 2010/003257 AI is double-walled and has a continuous and stepless inner wall. The curved inner profile of very short single-wall region is not aligned with the substantially straight peripheral profile of the Ge ^¬ fäßes so that the profile shown is unsuitable for example for stacking.

On the other hand, a stackable heat-insulating paper cup is known from DE 10 2004 056 932 Al. The thermal insulation is achieved by a double-walled construction of an outer and a spaced inner shell. The indoor and outdoor Coat have substantially the same length and erstre ^¬ ck each of a lower crimping roll, which is ^¬ Essentially at the bottom end of the cup - especially below the cup bottom - is arranged, to an upper crimping roller, which forms the upper edge of the cup.

The DE 203 14 276 Ul shows a drinking vessel with a handle and an inner relief, which inner relief preferably has a stack ^¬ edge, which facilitates unstacking. However, the drinking vessel is at no point doppelwanding and otherwise has no heat-insulating properties. Another stackable drinking vessel is described in US Pat. No. 6,065,603 A, whereby insulation of the glass, in particular a double-walled embodiment, is also not shown here.

It is an object of the invention to provide a vessel of the type mentioned, on the one hand has good thermal insulation ^¬ properties and on the other hand, a space-saving position ^¬ tion of many similar vessels, as it is desirable, for example, in the catering allowed.

This is inventively achieved in that an inner profile of the single-walled region of the vessel is at least partially matched with an outer profile of a lower stacking area of a wide ^¬ ren, similar vessel such that the Ge ^¬ vessels are stackable. Due to the corresponding design of the inner profile in the upper region of the vessel and the outer profile of the lower double-walled Dämmbereichs thus suitable for the catering vessel is created, which also has the advantages of a thermally insulated double-walled vessel. The space saving achieved and the stability during stacking and the ^fact that the maximum number of vessels in a stack can therefore be simply determined by the choice of a suitable height of the stack

single-walled area.

To achieve a high stability in the nested inserted position of at least two vessels, it is advantageous if the outer profile of the lower stacking area to form ei ^¬ nes game at least partially corresponds to the inner profile of a obe ^¬ ren stack region. It is furthermore suitable if an upper matches the further vessel to ^¬ participating stacking region substantially coincides with the single-walled area, so that the danger of damage to the inner wall of the double wall portion forming container ^¬ ses is reliably avoided. In addition, the outer profile of the lower stacking area can have a significantly greater circumference than the inner profile in the double-walled area would allow and thus the inner volume of the vessel despite the partially dop ^¬ pelwandigen design and regardless of the wall distance in the double-walled area be relatively large.

In a preferred variant, the vessel is substantially frusto-conical, whereby particularly good stacking properties are achieved, without giving the impression that the mold is subjected exclusively to the stacking function.

In addition, the exterior profile of the vessel can be above ^¬ semi-insulating region of the at least partially tapers in the upward direction at one point. By tapering the outer profile above the double-walled region of the inner profile for Bil ^¬ extension of the single-walled region can approximate at least partially. An opposing step on the inner profile above the doppelwandi ^¬ gene region may therefore be reduced or even completely the vermie ^¬.

It also proves to be advantageous if the Außenpro ^¬ fil the vessel is extended at one point upwards. By thus also expanded inner diameter, the stackability is particularly favored.

Conveniently, the vessel also has a grip area with substantially the same shape and smaller circumference with respect to the rest of the outer profile. The handle portion prevents slipping on the vessel and returns through the lower circumference to the user haptic information as to what amount he holds the vessel, which - even without visual inspection - the feeling of a Siche ^¬ ren balance is mediated.

If, in the grip region, a cover, preferably a cover ring, preferably consists of a material different from the vessel Plastic, in particular made of silicone, the grip safety is further improved. In addition, the stacking security can be increased if the cover in the stack acts as an intermediate layer between two vessels. If the vessel walls ^¬ for example consist of glass, a scratch of the glass can be prevented, and stack noises when stacking several vessels can be reduced.

In a preferred variant of the vessel of the invention is an externally disposed on the vessel cover, preferably a covering ^¬ ring, arranged in a transition region of the double-walled region in the single-walled area. Using this arrangement, the transition between the double-walled and the single-walled area can be concealed so that the vessel initially, particularly in the filled state, appears continuous einwan ^¬ dig and the impression of a relatively large Innenvolu ^¬ mens arises for the user. In addition, the cover of the additional thermal insulation between the vessel or its contents and the environment, for example, the surrounding room air or the hand of a person who touches the vessel on the cover ring.

It proves to be advantageous if a base with a smaller circumference is formed on the underside of the vessel. In this case, the indentation or step may be selected such that it corresponds to a step in the inner profile of a lower vessel in the stack, whereby the stability during stacking is further improved.

In addition, a cover made of a different material from the vessel, preferably made of plastic, insbeson ^¬ particular silicone, may be arranged on the base. Thus, the stability of the vessel is on the one hand improved to a smooth and possibly rut ^¬ schigen underground and on the other impacts are Zvi ^¬ rule the lower edge of the vessel and any steps in

Inner profile of another vessel steamed when stacking.

For the thermal insulation, it is advantageous if the double-walled area encloses a cavity. The insulating properties can thus be set up in a simple manner by a suitable choice of the dimensions of the cavity. In particular, good insulation properties are achieved if the cavity contains air, since this has a low thermal conductivity.

The invention will be described below with reference to particularly preferred embodiments, to which it should not be limited, and with reference to the drawings even further erläu ^¬ tert. The drawings show in detail:

Fig. 1 is a side view of a vessel according to the invention without covers;

FIG. 2 shows a vessel according to FIG. 1 with covers; FIG. and

3 is a sectional view of two stacked vessels of FIG .. 2

In Fig. 1, a substantially frusto-conical vessel 1 is shown, which has an opening 3 on an upper side 2 ^¬ . The opening 3 is bounded by an upper edge 4. Unge ^¬ approximately halfway up the vessel 1, a handle portion 5 is provided substantially vertically centered, wherein the vessel 1 in the handle portion 5 has a smaller compared to a continuous truncated cone shape circumference. At the lower and upper edge (6 and 7) of the handle portion 5, the outer profile 8 of the vessel 1 has a taper 9 respectively an extension 10, which are each formed by an edge or a bead.

The vessel 1 is formed from the upper edge 4 to a lower edge 6 of the handle portion 5 single-walled. Below the handle portion 5 ^¬ 1, the vessel has a double-wall portion 11, which is achieved in that the wall of the vessel 1 has an outer portion 12 and - having an inner part 13 - positioned therein. Between outer part 12 and inner part 13, a hollow ^¬ space 14 is formed, which contains substantially air. Through the double-walled region 11 and the air trapped in the cavity 14, a thermal insulation with respect to the outside of the vessel 1 is achieved. Here, the volume of the cavity 14 determines the degree of thermal insulation. In particular, the configuration of the inner part 13 may be selected such that suitable insulating properties are achieved. be targeted. Due to the thermal insulation, a temperature compensation of the vessel contents is reduced both with the outside air surrounding the vessel 1 and with a substrate, with which the bottom 15 of the vessel 1 can be in thermal contact. In addition, an unpleasant feeling due to very high or very low temperatures, for example, when touching the vessel 1 is prevented.

On a bottom 16, the vessel 1 has a base 17. The base 17 is formed by an inwardly step or indentation 18. Therefore, the bottom 15 has a smaller diameter than would be the case with a continuous truncated cone shape of the vessel 1. The thus-reduced area of the bottom 15 additionally reduces the thermal conductivity Zvi ^¬ rule the contents of the vessel 1 and a substrate. In addition, the stage 18 may be formed such that they are in Sta ^¬ PelN in another receptacle 1 '(s. Fig. 3) in an extension 26 fits inside the wider vessel.

Fig. 2 shows a vessel 1 (see Fig. 1) with a cover ring 19 in the handle portion 5 and a cover 20 on the base 17. The cover ring 19 and the cover 20 are both formed of silicone. The cover ring 19 has on one side an advertising space 21, which may show, for example, a logo. To increase grip safety, the cover ring has a groove structure. Since the covering 19 covers the entire grip portion 5 and thus also a transition from the double-wall portion 11 in a single-walled portion 22, the container 1 appears at first glance, a total of single-walled and has a (apart from the grooves ^¬ structure) is substantially planar outer surface on.

In addition to the covering function, the covering ring 19 also fulfills an insulating function. It is thus formed by the double-walled region 11 together with the cover ring 19 in the handle portion 5 an enlarged Dämmbereich extending from the upper edge 7 of the handle portion 5 down to the bottom 15. By the

Cover 20 on the base 17 is in the area of the bottom 16, the heat insulation even further improved.

The cover 20 also prevents slipping of the vessel 1 on a smooth surface and serves to protect the vessel 1 during stacking, since it forms a shock-absorbing layer between the vessel 1 and a further vessel 1 '(see Fig. 3).

When the cover ring 19 compensates for the reduced in the handle region 5 circumference substantially and the cover 20 18 also compensates for the classification of the base 17 substantially, the outer profile 8 of the vessel 1 is substantially continuous cone ^¬ conical shape.

FIG. 3 shows a section of the vessel 1 according to FIG. 2 with another similar vessel 1 '. The further vessel 1 'is stacked in the vessel 1. At an opposite side of the outer profile 8, the inner profile 23 of the vessels 1, 1 'can be seen. In the single-walled area 22, the inner profile 23 essentially follows the outer profile 8 of the vessels 1, 1 '. ^{By way of} example, the inner profile 23 has an extension 26 in a substantially same height as the extension 10 on the outer profile 8. In the double-walled region 11, however, the inner profile 23 deviates from the outer profile 8 and is determined by the shape of the inner ^¬ part 13.

The arrangement of the further vessel 1 'in the vessel 1 during stacking is predetermined by the inner profile 23 in an upper stack area 25 and the outer profile 8 in a lower stack area 24. As shown in FIG. 3, during stacking, the lower stack area 24 of the further vessel 1 'fits into the upper one

In the illustrated preferred embodiment, the upper stacking area 25 is substantially identical to the single-walled area 22. The bottom of the further vessel 1 'is thus stacked at a level with the lower edge 6 of the grip area 5 of the Vessel 1 arranged. The Abde ^¬ ckung 20 of the other vessel 1 'is in contact with an extension 26 of the inner profile 23. The extension 26 is due to the smaller inner diameter of the inner part 13 in the double-walled area 11 or by the distance between the inner part 13 and outer part 12 and the radial extent of the cavity 14th

In the example shown in Fig. 3 open the inner part 13 and the outer part 12 in the single-walled area 22 by the outer part 12 tapers and the inner part 13 expands. Alternatively, for example, each one of the two parts can pass straight into the single-walled area 22 while the other part is either tapered or widened.

In the example shown, the upper stack area 25 overlaps with the lower stack area 24 of the same vessel 1, as a result of which more than half the height of the further vessel 1 'can be introduced into the vessel 1. But it is also conceivable that the stack ^¬ areas 24, 25 do not overlap. For example, the lower stack area 24 may be provided substantially identically to the double-walled area 11. It is only essential that the two vessels 1, 1 'are stackable, ie that the further vessel 1' at least partially into the vessel 1 ^{¬ a} feasible and in the inserted position positively, preferably with play, ie not completely immovable held becomes .
