TITLE

Vessel with cuff

TECHNICAL AREA

The present invention relates to a vessel, in particular a drinking vessel for drinks, such. a cup.

STATE OF THE ART

Cups made of ceramic materials such as stoneware, stoneware or porcelain have long been known. Such cups are typically coated with a glaze which forms a vitreous, liquid-impermeable surface layer to enhance the cup's sealing and durability and to give the cup a more refined appearance. Such a glazed ceramic cup can easily slide out of the hand in use, especially when the cup is grasped with wet hands. The same applies to glass vessels etc.

For plastic cups, it is known from the prior art to provide such a vessel at least partially with a non-slip coating or a non-slip sleeve. The coating is usually inextricably linked to the cup.

PRESENTATION OF THE INVENTION

The object is to connect a cuff easily and yet safe to use with a vessel body. This object is achieved by a vessel, such as a drinking cup, with the features of claim 1. Preferred embodiments are in specified in the dependent claims.

Thus, there is provided a vessel comprising: a vessel body, wherein the vessel body defines a vessel interior, with a vessel bottom and a circumferential outer wall extending upwardly from the vessel bottom, and an annular collar of an elastic material, e.g. Sucker gum or another elastomer that surrounds the vascular body on the outside, wherein the cuff rests in a support area on the outside of the outer body of the vascular body, wherein the vascular body in the support area of the sleeve at least a region of increased surface roughness (compared to the outside surface roughness of the outer wall outside the support area) ,

By specifically providing a region of increased roughness in the support area of the cuff, the cuff adheres better to the outer wall of the vessel without slipping off in normal use. The region of increased roughness can extend over the entire support surface of the sleeve, or it can be formed only in partial areas of the support surface.

In a preferred embodiment, the vessel body is made of a ceramic material and has a glaze. In order to achieve an increased roughness, there is then no glaze or glaze with increased roughness at least in regions in relation to the glaze existing outside the contact area in the contact area. The region of increased roughness is preferably achieved by the fact that in the production of the cup in this area no glaze is applied, so this area is omitted when applying the glaze, or that in this area a glaze is applied, which has a higher surface roughness than the has glaze used outside the contact area, for example by admixing particles. An increased roughness can also be achieved by roughening or completely removing an originally present burnt glaze by suitable processing, eg sand blasting. The region of increased roughness can also extend over the entire bearing surface of the sleeve, or he can only in some areas of the Support surface be formed. In particular, the glaze existing outside the contact area can extend to below the sleeve at the edges of the sleeve in order to achieve an attractive appearance in this area. On the other hand, outside the contact area of the cuff, the glaze preferably substantially completely covers the outer wall on the outside in order to achieve improved resistance and an appealing appearance of the vessel.

Preferably, the vessel body is made of a ceramic material which is substantially impermeable to water even in the absence of a glaze. The term "substantially" refers to conditions in normal household use: a material is considered to be substantially impermeable to water if a vessel of this material is left for a longer period of time (eg 24 hours) in a normal dishwasher cycle or when left standing with filled water. In general, ceramic materials that are fired at higher temperatures (especially porcelain) are more heavily sintered and thus less permeable to water than those fired at low temperatures (eg, so-called stoneware.) In a substantially water-impermeable material In the area of the support surface of the sleeve can be dispensed with a glaze, without the performance characteristics of the vessel are deteriorated in household use.

In another preferred embodiment, the vessel body is made of glass. In order to achieve an increased roughness, the support area is at least partially roughened, e.g. by sandblasting. Even if the vessel body is made of other materials, e.g. made of plastic, it can be roughened accordingly in the support area.

Preferably, the outer wall has an annular circumferential taper, to which an upper outer wall area adjoins the upper side and a lower outer wall area at the bottom. In this case, the taper has a surface which is set back relative to the surface of the upper outer wall portion and the lower outer wall portion to form one step in each case. The surface of the taper then preferably has at least a region of increased surface roughness. Preferably, the entire surface of the taper has an increased surface roughness. Thanks to the steps, the transition from smooth to roughened area in a defined and thereby aesthetically pleasing manner done. The cuff is then placed between the steps in the area of the taper and rests on the surface of the taper. Due to the steps, the cuff is additionally prevented from slipping off.

Preferably, the collar is stretched elastically in the circumferential direction and is thereby held adhesive-free removable on the vessel body. Thus, the installation of the cuff is very simple by the cuff is simply pushed onto the vessel body. This is very easily possible, in particular, when the vessel body widens upwards. For cleaning purposes, however, the cuff can be easily removed.

In a preferred embodiment, the vessel body is double-walled. In other words, there is an inner bottom which is spaced above the vessel bottom above it, and a circumferential inner wall extending upwardly from the inner bottom which is spaced apart from the outer wall to form a gap and in an upper end region with the outer wall connected is. This results in a good insulation effect, so that warm drinks stay hot longer and cold drinks remain cold for longer, and cold drinks prevent the formation of condensation on the outside.

For ease of manufacture, the vessel bottom may then have an opening which provides access to the gap. This opening is then preferably closed by a plug made of an elastic material.

While the outer wall preferably has a taper, the inner wall towards the vessel interior preferably has a continuous, step-free surface in order to facilitate the cleaning. This can be easily achieved in a double-walled vessel, since the shape of the outer wall has no influence on the shape of the inner wall.

In order to optimize the adhesive properties, the sleeve preferably has a flat inner surface which rests flat on the outer wall of the vessel body. The On the other hand, the outer side of the cuff can optionally be provided with structures such as grooves, knobs, etc. in order to improve the grip and / or to influence the appearance.

DESCRIPTION OF PREFERRED EMBODIMENTS

In Fig. 1 a Gefasskörper 1 is shown, in Fig. 2 an annular, band-shaped sleeve 3. Together, these parts form the in Fig. 3 in section represented vessel, a drinking cup.

The Gefasskörper 1 is double-walled. It comprises an outer part 10 with a circular outer vessel bottom 11 and an outer wall 12 extending upward from it, which widens upwards. In its upper end region 18, this outer wall 12 is connected to the upper edge of an inner part 20 which has an inner bottom 21 and an inner wall 22 extending upwardly therefrom. In this case, an insulating gap 24 is formed between the outer part 10 and the inner part 20. The vessel body 1 defines with its inner bottom 21 and its inner wall 22 a vessel interior 23 for receiving a beverage.

The outer Gefassboden 11 is provided with a central opening, which is present for manufacturing reasons and forms an outer access to the gap 24. This opening is closed with a stopper 4, the out an elastic material, such as silicone rubber, is made. It has an annular region 41 extending through the opening, at the lower end of which a flange 43 is formed, which extends laterally outwards and prevents the plug from being pushed through the opening. A circumferential bead 42 at the upper end of the annular area retains the plug in the opening. This design of the plug manufacturing tolerances in the diameter of the opening can be easily compensated. The plug may be provided with one or more fine openings which are gas permeable but liquid impermeable to allow pressure equalization to the gap. At its lower edge, the vessel body is provided with a circumferential, annular projection 19, which may be interrupted, forms the base of the vessel and protrudes downwards beyond the stopper.

In the outer wall 12, a taper 13 is formed. This taper has a surface which extends slightly inwardly towards the outer wall regions 14, 16 adjoining upwards or downwards. At the transition between the taper and the adjoining outer wall areas defined steps 15, 17 are formed.

The vessel body 1 consists of a ceramic material, as it is commonly used for dishes, e.g. Porcelain. It is provided with a graphic not shown glaze, which covers at least the inner part to the vessel inside and the outer part on its outer side substantially (ie apart from production-related points) completely, with the exception of the entire area of the taper 13 in this area is at the manufacture of the vessel body no glaze applied. In this way, the surface of the taper has a larger surface roughness than the adjoining areas of the outer wall. If a water-impermeable ceramic material such as porcelain is used, the vessel body is nevertheless tight and dishwasher-safe, and no water can penetrate into the intermediate space 24. Otherwise, if necessary, water could also be removed through the opening in the bottom of the vessel.

The cuff 3 is pushed from below onto the vessel body 1. She has one smooth inside 31 and provided with circumferential grooves outside 32. The cuff 3 is made of elastic silicone rubber. It lies with its inside on the surface of the taper 13 and is biased elastically in the circumferential direction. Because of this tension, the cuff is held on the taper. An adhesive is not needed. Slipping of the sleeve is prevented by the surface of the taper 13 being rougher than the adjacent portions 14, 16. In addition, the steps 15, 17 help to hold the collar in place. However, if necessary, the cuff can be easily removed.

Of course, a variety of modifications are possible. Thus, the vessel can also be single-walled. Instead of a drinking cup, a different kind of container, for example a flower container, can be provided with a cuff in the manner mentioned. This may consist of a ceramic material other than porcelain, for example, simple clay-based earthenware. It may, for example, be made of glass, wherein the surface of the taper 13 has been roughened by sandblasting. The cuff need not be made of silicone rubber, but may be made of any elastic material, such as rubber-based rubber, Santoprene ™ or other elastomers. On the outside, it can also be structureless or, instead of the grooves shown here, have a different type of structure, eg knobs or raised letters or symbols. Many other modifications are possible without departing from the scope of the present invention.
