Kannenartiaer item

The present invention relates to a jug-like object according to the preamble of the main claim. Such jug-like objects are generally known and can be found in every household.

In principle, such objects serve to hold liquids or drinks and are therefore preferably used as tableware.
20

However, after use, such objects generally have to be cleaned outside and/or inside at a relatively high level of effort.

In addition, storing these items in the refrigerator is not always possible due to their external dimensions. In such cases, the liquids must be poured into smaller containers in order to be able to store these smaller containers in the refrigerator.

It is therefore an object of the invention to further develop the known jug-like objects in such a way that they no longer require any complex external or internal cleaning, particularly after use, while having improved usage properties.

The invention solves this problem with the features of the main claim.

The invention provides the advantage that the interior is prepared for the direct placement of commercially available cardboard beverage containers.

This advantage is achieved by a straight-cylindrical interior whose surface lines are practically parallel to each other.

The conventional cardboard beverage containers, which are sold, for example, under the name Tetra-Pack®, can therefore easily be placed into the jug-like objects according to this invention.

In principle, the free inner cross-section circumscribes the rectangular outline of such cardboard-like beverage containers so closely that the beverage container sits firmly within the jug-like object.

The straight-cylindrical interior is of key importance. This ensures that a large number of basic shapes of the jug-like container according to the invention can be reduced to just a small number of basic shapes of such beverage containers, for example 0.5 l or 1 l milk cartons, 1 l red wine cartons or orange juice cartons, etc.

0 The outline of the inscribed envelope corresponds in principle to the outline of the intended cardboard beverage container. This is then inserted into the interior of the jug in a practically tight fit and is fixed there.

In addition, the straight-cylindrical interior can also

be provided with inward-projecting retaining projections that protrude only a few millimeters into the interior. This strengthens the holding function on an inserted cardboard container.

This technical function can also be performed by a narrowing of the interior space at the bottom, which serves to clamp the inserted cardboard container in the bottom area.

An embodiment in which the chamber wall is double-walled is advantageous.

In addition to the additional insulating effect, this measure also provides extensive design freedom for the floor plan of the outer wall, which, in contrast to the rectangular floor plan of the inner wall, can be round, elliptical, hexagonal, pentagonal or similar.

In addition, it can be provided that the cavity between the inner wall and the outer wall is filled with a cold storage medium, for example salt water.

This cold storage medium can be installed at the factory or can be individually filled in via a separately provided inlet opening.

With these measures, a good, long-term cooling effect can be achieved on the inserted cardboard container, which can even be extended to temperatures below the freezing point of water.

In the case of the jug-like objects according to this invention, pouring spouts in the area of the edge of the opening arranged at the top are completely unnecessary, since the

Cardboard containers usually have suitable pouring spouts.

Since the drinks to be served always remain in their original cardboard containers, all embodiments of the invention also eliminate the need for laborious internal cleaning after each use. If the container becomes dirty, a single wipe/rinse is sufficient to clean it.

The arrangement of the handle in the longitudinal direction of the hollow cylinder, i.e. essentially parallel to the surface lines, promotes ergonomics and is user-friendly. The features of claim 6 are given particular attention, as this avoids unnecessary accumulation of material in the edge area of the chamber wall. These measures therefore serve to simplify production and reduce internal material stresses. However, these measures also exploit the fact that the commercially available cardboard-like beverage containers are already provided with pouring spouts and can therefore be conveniently inserted into the interior in a rotating position that positions the pouring spout opposite the handle.

In addition, the object according to the invention offers the possibility of large-scale and inexpensive advertising, for example for a certain drink, for a certain company or the like.

0 It is also proposed to manufacture the jug-like object from plastic material. This offers the possibility of inexpensive mass production.

Further embodiments emerge from the subclaims.

The invention is explained in more detail below using exemplary embodiments. They show:

Unless otherwise stated below, the following description always applies to all figures.

The figures show a jug-like object 1. This jug-like object consists of a hollow cylindrical jug wall 2, to the outside 3 of which a handle 4 is attached.

At the lower end, the hollow cylindrical can wall 2 forms a base 5 and offers an opening 6 at its upper end.

It is now essential that the interior space 7 is essentially straight-cylindrical. The chamber wall enclosing the interior space therefore has essentially exclusively parallel surface lines which in principle extend over the entire height of the can wall.

In addition, the free inner cross-section is limited by an envelope 8 inscribed in 0, which has a rectangular floor plan.

The examples shown represent the limiting case of a rectangular floor plan. The 5 sides of the rectangle are all the same size. This results in a square floor plan.

The floor plan dimensions can be varied as desired within the usual cross-sectional dimensions of commercially available cardboard beverage containers. In any case, however, a rectangular or square floor plan is necessary in order to meet the requirement for extended usage properties.

In addition, the figures show double-walled chamber walls. These double-walled chamber walls consist of an inner wall 9 and an outer wall 10, between which a cavity 11 is formed.

This measure offers the advantage of good insulation with minimal material expenditure.

In addition, provision can be made to fill the cavity 11 with a cold storage medium 12. For this purpose, easily closable filling openings 13 can be provided if necessary.

Furthermore, it is essential that no pouring spout is provided on the side 14 opposite the handle 4 at the upper edge of the opening 6.
25

The edge of the opening 6 is therefore closed and preferably has a uniform curvature, since the pouring function is performed by a corresponding spout of the cardboard-like beverage container, which is inserted into the jug-like object according to this invention from above.

If the handle 4 extends, as shown, in the vertical direction 15 of the container, ergonomically advantageous handle shapes can also be realized for such jugs of low height.

In addition, it is shown that the chamber wall 2 has mutually parallel surface areas 16 on two opposite sides, namely on the side of the handle 4 and the opposite side 14, and that the handle is located on one of these mutually parallel surface areas 16.

Fig.l shows a chamber wall with a basically circular cross-section. Here, the mutually parallel surface areas are provided by diametrically opposed jacket zones of the outer wall, whereby an additional accumulation of material in the contact area 22 between the inner wall 9 and the outer wall 10 is avoided.

In addition, it can be provided to apply an advertising medium 17 to the outside of the outer wall 10 in order to draw attention to the origin of the object according to the invention or the content.

In addition, Figs. 1 and 3 show that the inscribed envelope 8 is surmounted by inwardly directed projections 18, 19 which extend only a few millimeters beyond the envelope 8 into the interior 7.

In the present embodiment, these projections 18, 19 consist of vertically extending ribs which enclose an inserted cardboard container from diametrical sides and in this way reliably fix it against falling out.

In addition, it can be provided that the projections 18, 19 do not extend into the bottom area of the interior 7 but end a little 20 in front of the bottom 21 of the interior 7. In this way, the inserted cardboard container is enabled to elastically recline somewhat in the lower area, so that an additional holding function is achieved.

Such jugs should preferably be made of plastic material, in particular, roughened surfaces are preferred.

The figures also show a special case in which the right-cylindrical interior 7 has a square floor plan.
