Description

description

cups

The invention relates to a cup with a bottom and an adjoining jacket, wherein the jacket provided at its end facing away from the bottom end with a mouth roll and one or more layers may be formed, wherein at least one layer of the shell of paper or cardboard or other comparable Materials is made.

There are a variety of different such cups known. Often single or multi-walled cups are used. Multi-walled cups are mainly used in hot or chilled drinks, as there single-walled cups are often only uncomfortable to touch.

In all cup variants, however, there is the problem that they are only unpleasant to grab. This problem occurs especially with cups provided with a well layer. In addition, there is often also the problem that the outside of the cup is unpleasant hot or unpleasant cold depending on the content.

Furthermore, such cups are poorly printable with information and advertising. The invention is therefore based on the object to propose a cup design, which also has good tactile properties in addition to good insulation properties and also can be easily provided with information and / or advertising.

This object is achieved in that at least one layer of the shell is provided over its entire height and at least approximately the entire circumference with elevations and / or depressions, wherein the difference in depth between maximum increase or, recess and material layer or recess or Increasing over the height of the shell and / or varies over the circumference, and that the mouth roll may be formed on the inner or single layer.

As a result, the cup nestles very well when grasping in the hand. He can be taken for sure. Nevertheless, the stackability is not adversely affected. In addition, a multi-layered cup ensures very good insulation.

It has proved to be very advantageous if the distance between two adjacent elevations or depressions varies over the height of the shell.

This is a very good adaptation to the cup shape achieved without undesirable wrinkles.

Erfmdungs according to it is very advantageous if the elevations and / or depressions are formed as embossments.

By means of embossing there is a very great freedom in the design of the elevations and the depressions. It is also very advantageous if a plurality of discrete embossments, which are formed as mold elements, are distributed over the shell, which together form the elevations and depressions.

As a result, the coat can also make very appealing, and it is conceivable that through these embossing designs, presentations or advertising can be displayed.

Another very advantageous embodiment of the invention is also present when the elevations and / or depressions are arranged in line form.

Through the use of lines can be generated in a multilayer jacket air ducts, so that at least the outside of the shell is kept aligned by convection to the ambient temperature. But it is also conceivable that in a single-layer jacket by such a configuration, the contact surface is reduced to the hand of the user.

It is also very advantageous according to the invention if the elevations and / or depressions are arranged in the form of wavy lines.

With such wavy lines the cup is even better in the hand.

It is also extremely advantageous if the lines run at least approximately in the height direction of the jacket.

As a result, an occurring convection is not only supported on the outside of the shell. According to a further embodiment of the invention, it is extremely advantageous if the depth of the elevations and depressions varies along the lines or in the direction of the mantle height.

This makes it possible to design a jacket, which is formed, for example, at its upper and / or lower edge flat with leaking elevations and depressions or in which the elevations and depressions are formed lower in inner regions and thus ensure better tangibility.

It is also extremely advantageous according to the invention if the contact surface between the inner surface and the outer surface of the cup is reduced.

A reduced contact surface reduces the heat transfer between inside and outside.

It has proved to be very advantageous if the elevations are formed such that at least in the grip area, the inwardly directed contact surface is smaller than that of the outward elevations.

This ensures a good and pleasant handling. Nevertheless, a very good insulation with low heat transfer is ensured.

Another very advantageous embodiment of the invention is also present if the elevations are formed such that at least in the grip area, the inwardly directed contact surface is greater than that of the outward elevations.

As a result, a significant reduction of the contact area between the hand and the cup is also achieved, whereby a lower heat transfer takes place. Of the Cup can thus be easily handled even with very hot or very cold content, even if the cup is formed single-layer.

It has proven to be extremely advantageous in this context if the ratio between the inner contact surface and the outer surface is 1: 2.

As a result, a particularly low heat transfer and a very good insulation effect is achieved.

According to the invention, it has also proved to be very advantageous if the jacket has at least one region which is substantially smooth.

It has proved to be very advantageous if information is provided in the smooth area.

It is also very advantageous if imprints are provided in the smooth area.

In this smooth area advertising or other information can be provided by inking and / or embossing.

A very advantageous development of the invention is also present when the multi-layered jacket has at least two embossed layers.

It has proved to be very advantageous if the imprints of the layers are directed against each other.

As a result, a very good insulation of the shell is achieved. Erfmdimgs according to it is also extremely advantageous if the embossments of the layers abut each other.

As a result, a comparatively large distance between the layers is created even with a small embossing depth. In addition, such imprints are very stable.

But it is also very advantageous if the multi-layered jacket has a smooth position.

Very good printability can be achieved if the smooth layer is directed outwards.

It has proved to be very advantageous if a smooth layer is provided as the inner layer of the shell and this is tightly connected in itself and with the ground.

As a result, the contents of the cup can not be fixed to imprints.

A further very advantageous embodiment according to the invention is also present when the layers are tightly connected to each other at their upper and / or lower end.

Thereby, the penetration of liquid, dirt, dust or the like between the layers can be prevented.

It is also very advantageous if the jacket and / or the layers are glued in themselves.

This creates an outer jacket or layers that can be easily pushed over the cup afterwards. Another according to the invention very advantageous training is also present when the jacket is formed overlapping and when the second, outer end of the shell is equipped with a bond which is arranged set back relative to the outer end.

This avoids that adhesive is able to leak at the end edge of the shell. The return can also be so great that the bonding of the second end takes place with the inner shell.

Furthermore, it has proved to be extremely advantageous if the mouth roll is formed on the inner layer.

This results in a greater comfort when using the cup.

It has also proved to be very advantageous according to a further development of the invention, when the outer layer has a given by the different levels surveys anti-slip.

This makes the cup even easier to handle. Accidental slipping out is avoided. In addition, the cup nestles very pleasant in the hand of a user.

Another very advantageous embodiment of the invention is also present when the outer layer has at least one thickening.

It has proved to be very advantageous if the thickening is provided in the central region of the height of the shell.

As a result, a very good gripping and anti-slip of the cup is achieved. Another very advantageous development of the invention is also present when at least one perforation is provided in the jacket.

It has proved to be extremely advantageous if the perforation is provided in the outer jacket.

Such a design results in many design options.

It is extremely advantageous according to the invention if a perforation is provided at the upper and / or lower end of the jacket

This ensures that air can flow within at least approximately in the direction of the cup height extending channels. The air enters at the bottom of the cup and out at the top of the cup, provided that the cup content is warmer than the environment. The flow is generated by convection. A differently directed flow with cold cup contents is additionally conceivable.

It is also very advantageous if that a coupon is provided which is delimited by a perforation from the rest of the jacket.

Thus, for example, coupons or other advertisements can be attached to the cup.

Another very advantageous embodiment of the invention is also present when the outer shell covers a partial height of the cup height.

Thus, the outer insulating jacket can be provided in the grip area.

It is also very advantageous if the outer jacket has recesses. By means of these recesses, for example, viewing window can be created on the inner shell or on the contents.

In the following the invention will be illustrated with reference to several embodiments.

Outside surface is greater than the contact surface of the outer shell on the inner cup.

1 with a manufactured from a paper or a cardboard cup with a bottom 2 and a shell 3 is shown in Fig. 1. At the end facing away from the bottom 2 of the shell 3, an outwardly wound mouth roll 4 is attached, which comprises the opening of the cup 1.

In the first embodiment, the jacket 3 of the cup 1 is double-walled and consists of an inner jacket 3a made of a smooth material and an outer jacket 3b provided with a structure 5, which is wrapped around the inner jacket 3a. In this case, a first end of the outer jacket 3b along the height to the inner shell 3a is connected by an adhesive seam 6, which may be arranged offset from the end. The adhesive seam 6 may preferably be set back between one and eight millimeters, in order to avoid leakage of the adhesive used for the adhesive seam 6 at the end. The adhesive seam 6 can also be constructed from discrete points or other geometric configurations. Depending on the intended use of the cup 1 and the materials used, a wide variety of hot, cold or even dispersion adhesives can be used for the adhesive seam 6.

The second end of the outer jacket 3b may overlap the first end and is secured in the region of the first end with a further adhesive seam 7. The two ends of the outer sheath 3b may overlap each other. It is conceivable that the overlap is between one and ten millimeters. But it is also conceivable that the ends only abut one another or even occupy a small distance from each other, which should not exceed one millimeter.

The outer sheath 3b is first glued to the first end and then wrapped around the inner sheath 3a.

The adhesive seam 7 can either attach the second end to the first end of the outer jacket 3b or on the inner jacket 3a. The same adhesives may be used as in the adhesive seam 6.

Also, the adhesive seam 7 may be arranged offset from the end, so that there is also the possibility that the second end of the outer shell 3 b is glued despite an overlap with the first end directly to the inner shell 3 a.

The inner shell 3a overlaps at its ends and is glued tight.

The outer jacket 3b is provided with wavy lines 8 which extend substantially in the direction of the height of the shell 3 and form the structure 5. The wavy lines 8 form elevations 9 and depressions 10. However, the designations elevations 9 and depressions 10 do not necessarily designate that these elevate or deepen in each case relative to a zero position which is defined, for example, by the original paper plane. Rather, the elevations 9 and the depressions 10 describe against each other elevations and depressions.

The height of the elevations 9 and depressions 10 can change over the mantle height. In this embodiment, a plurality of regions 11 of a weaker expression of the elevations 9 and the depressions 10 are arranged, which run around the outer casing 3b. Other arrangements are conceivable. Through these areas 1 1, the outer sheath 3b is griffsymphatischer. In addition, a slip guard is formed, which prevents accidental slipping. Nevertheless, this embodiment does not hinder the stackability of several cups 1 into each other.

In addition, smooth areas 12 can be provided which can carry information that is printed or embossed. It is also possible that 12 logos or the like are arranged in these areas. For example, region 12 is a slightly recessed circular surface that carries a logo.

By the structure 5 of the outer sheath 3b channels are formed which extend at least approximately in the direction of the mantle height and are closed by the inner sheath 3a, so that here correct, closed channels result, which may be open at their ends.

The air contained in the channels ensures a very good insulation effect. If, for example, a hot or cold beverage is filled into the cup 1, the cup 1 is nevertheless very easy to handle, since the outside of the outer casing 3b does not assume the high or low temperature of the beverage. The temperature balance of the beverage with the environment is also reduced.

If the channels are open at their ends, a cooling effect, for example for hot drinks such as coffee or the like, can also be achieved by the convection of the air through the channels in order to cool the beverage more quickly to a temperature that is beneficial for drinking.

It is also conceivable that 3b perforation openings 13 are provided at the upper and lower edges of the outer shell, which allow unhindered admission of air or air leakage from the channels. Furthermore, it is conceivable that the outer sheath 3 b has such a high inherent rigidity, that this only in predefined areas, preferably at the upper and / or lower edge of the inner cup 3 a rests and otherwise occupy a distance from the inner cup 3a, thereby achieving an even better insulation effect becomes.

It is also conceivable that the outer sheath 3b itself is formed multi-layered. It can be applied to the structured layer a smooth layer and connected to this. The smooth layer can be arranged either on the inside or outside.

It is also conceivable that the cup 1 consists of a plastic or any other materials and only the outer jacket 3b is made of paper or cardboard.

The outer jacket 3b can also be made separately from the cup 1 and then pushed onto the cup. Often the static friction is sufficient here. An adhesive connection is conceivable.

The above-described bonding can also have further splices on the circumference of the cup 1. It is also conceivable, for example, that the bonding takes place along the circumference of the cup 1. In this case, one or more splices or glue lines can be provided.

In Fig. 2 a section through the jacket 3 of the cup 1 is shown, so that the channels formed from the elevations 9 and depressions 10 can be seen.

The distance 14 between two adjacent elevations 9 or depressions 10 can vary over the height of the casing 3. In this first embodiment, the distance 14 in an upper region of the shell 3 is greater than in a lower region of the shell 3. By these different distances compensation for the available material is created, the adaptation to creates different diameters over the height of the cup 1. By this adjustment wrinkles or the like are avoided in the outer jacket 3b.

This also makes it possible to use only slightly elastic paper or cardboard for the outer sheath 3b under certain circumstances.

Fig. 3 shows a further embodiment of the invention. The cup shown here is designated 31. Here, instead of the structure 5 formed from wavy lines 8, a structure 35 formed from parallel lines 38 is provided.

In a central region 32 of the outer sheath 3b is bulged. This results in a circumferential thickening of the outer shell. This thickening is generated by a larger distance 33 of the lines 38 in this area. The greater distance 33 may be accompanied by a greater height of the elevations 9 and depressions 10.

A further embodiment of the invention is shown in FIG. 4. Here discrete embossments 48 are provided, which together form a structure 45 in their majority.

As in the first embodiment, the height of the embossments can also vary in this embodiment. As embossments 48, for example, logos or the like can be used.

In all of these multi-layered embodiments, it is also conceivable that a perforation 46 is provided which surrounds a jacket region 47, which is detachable as a coupon.

But there are also single-layer shell designs conceivable. FIG. 5 shows an embodiment which shows such a jacket 53 formed only from the structured outer jacket 3b. The casing 53 again has a depth of the structure 55 which varies over the casing height 53. The structure 55 runs in this example to the upper and lower edge of the shell 53 out, so that very easy the mouth roll 4 can be arranged and a tight connection with the bottom 2 can be created.

However, it is also conceivable that the depth also varies further.

Even with the single-layer design a variety of forms of structuring are conceivable.

In one embodiment, the depth of the structuring in the range between 0.1 and 2.5 millimeters, wherein the distance between adjacent elevations 9 and recesses 10 should be between 0.1 and 3 millimeters. The transition radii between the elevations 9 and depressions 10 may be in the range between 0.5 and 1, 25 millimeters.

The jacket 3b may be structured such that it represents, for example, a landscape or other images. The structuring can still be highlighted by a corresponding color. The color scheme can be based on the embossing.

The discrete imprints 48 can consist of logos, picture elements or any other representations, for example also text elements, which then together form a structuring of the sheath 3b.

According to the invention, it is also conceivable for the outer jacket 3b to occupy only part of the cup height. Thus, the outer shell can be limited to the grip area, for example. It is saved in non-insulating areas requiring the additional material for the outer jacket 3b. The outer jacket 3b can also be restricted to certain areas requiring stabilization.

In this context, it is also conceivable that the outer jacket 3b has recesses. These recesses can for example release the view of the inner shell 3a, or if this is transparent on the cup contents. Also in this variant, material for the outer sheath 3b is saved.

It is also conceivable that both the outer jacket 3b and the inner jacket 3a is structured or embossed, as shown in Fig. 6.

The embossing 4 of the two layers 3a and 3b are at least partially directed against each other, whereby the distance of the layers increases.

It is also conceivable that the structuring 5 is formed so that the inner jacket 3a facing surface is larger than the outwardly facing surface.

By this configuration, the heat transfer between the cup 1 and the hand of the user is reduced. It can also be kept cups that contain very hot or very cold product. In the example shown, the ratio between the areas is about 1: 2.

The outwardly facing surface may also be less than or more than 50% of the inwardly facing surface.

Such a design has proved to be very effective not only as shown in Fig. 7 in multi-layer cups, but especially in single-layer cups. It is also conceivable that the outwardly directed surface is larger than the inwardly directed surface, as shown in Fig. 8.

This is particularly suitable for multi-layer constructions. The larger outer surface ensures pleasant handling, while still achieving a very good insulation effect.

Despite this configuration, the cup 1 can still be kept very comfortable. In particular, no unpleasant pressure points arise. This is mainly due to the changing depths of structuring.
