Title: Cover for glass

Description:
Described is a cover for glasses, for example for glasses in shape of goblet or the like. The cover allows it to adopt a condition of fitting on the glass in which it covers at least partly the glass and, by means of its shape and/or its structural features, it is able to keep oneself in the fitting condition. Moreover, the cover, in this fitting condition, allows the visibility of the drink contained in the glass, if the glass is at least partly transparent. 
     As is known, the glasses in the form of a goblet or the like are normally used for drinking cool drinks (in particular wine) during parties, receptions and meetings. During these occasions one talks with the other people whilst holding the goblet in one&#39;s hand and sipping the drink and, therefore, the temperature of the drink gradually increases so much so that sometimes the drink become no longer drinkable. Moreover, the handgrip of the goblet may, over time, not be completely effective because with the variation in temperature it could become slippery on account of the sweat transmitted from the user&#39;s hand. 
     The aim of the invention is to provide a cover for glasses which overcomes these drawbacks. 
     Another aim of this invention is to provide a system for providing drinks or beverages which overcome these drawbacks. The system for providing drinks or beverages according to this invention comprises a cover according to this invention and a glass.

     Numeral  1  in  FIGS. 1 to 6  denotes a preferred embodiment of a cover in accordance with the invention. A glass for which the cover  1  may be used is indicated in  FIGS. 7 and 8  with B. The glass B is for containing a drink or beverage. 
     The cover  1  is for covering and/or coating at least partly the glass B. The cover  1  is for covering and/or coating at least partly the glass and simultaneously at least partly or totally thermally insulating the glass B and/or the drink or beverage in the glass B. 
     A preferred embodiment of a system for providing or administering a drink or beverage according to this invention comprises the cover  1  and the glass B. 
     The cover  1  comprises a wall  11 . 
     The wall  11  is at least partly or totally thermally insulating. For this purpose, the wall  11  comprises and/or is made of at least one material with certain properties and/or features. The at least one material has certain properties in terms of thermal insulation. The at least one material is preferably thermally insulating. The at least one material may have certain surface features or properties in terms of roughness and/or friction. The at least one material may have certain structural features or properties in terms of flexibility/rigidity, in such a way as to be elastically deformable. 
     The wall  11  defines a cavity  110 . The cavity  110  is designed to receive the glass B. The cover  1  is configured in such a way that the glass B can adopt an inserted position of the glass B in the cavity  110 . When the glass B adopts the inserted position, the glass B is inserted in the cavity  110  defined by the wall  11 . 
     The glass B can adopt a not inserted position. When the glass adopts the not inserted position, the glass B is not inserted in the cavity  110 . In  FIGS. 9 to 14 , the glass B adopts the inserted position. In  FIGS. 7 and 8 , the glass B adopts the not inserted position. 
     The wall  11  stably adopts a non-deformed configuration. In  FIGS. 1 to 6  and in  FIGS. 9 to 14  the wall  11  is in the non-deformed configuration. When it is in the non-deformed configuration, the wall  11  is shaped in such a way as to reproduce the outside shape of at least a part of the glass B. In this way, when the glass B adopts the inserted position, the wall  11  coats and/or cover said at least a part of the glass B. 
     The wall  11  retakes substantially said outer shape of the said at least a part of the glass B, in order to be designed to coat said at least a part of the glass B. 
     The wall  11  may adopt a condition of fitting on the glass B. The condition of fitting of the wall  11  on the glass B can be defined a fitting condition of the wall  11 . 
     When the wall  11  adopts the fitting condition, the glass B adopts the inserted position. 
     The wall  11  may adopt a condition of not fitting on the glass B. The condition of not fitting of the wall  11  on the glass B can be defined a not fitting condition of the wall  11 . 
     When the wall  11  adopts the not fitting condition, the glass B adopts the not inserted position. 
     The wall  11  in  FIGS. 1 to 6  adopts the not fitting condition. 
     The wall  11  in  FIGS. 9-14  adopts the fitting condition. 
     The fitting condition of the wall  11  corresponds to the inserted position of the glass B. The not fitting condition of the wall  11  corresponds to the not inserted position of the glass B. 
     The wall  11  has at least one opening  11   a . The opening  11   a  allows the glass B to move from the not inserted position to the inserted position by a first passage of the glass B through the opening  11   a . The opening  11   a  allows the glass B to move from the inserted position to the not inserted position by a second passage of the glass through the opening  11   a.    
     The wall  11 , by means of the structural features of the above mentioned at least one material, is elastically deformable in order to be able to adopt a first deformed configuration. The first deformed configuration is not shown in the accompanying drawings. When the wall  11  adopts the first deformed configuration, the wall  11  allows the first passage of the glass B through the opening  11   a.    
     The wall  11  is configured, when the glass B has been subjected to the first passage and adopts the inserted position, to be subjected to a first elastic return movement. The first elastic return movement of the wall  11  is a movement of the wall  11  from the first deformed configuration of the wall  11  towards the non-deformed configuration of the wall  11 . The first elastic return movement may be a movement of the wall  11  from the above-mentioned first deformed configuration of the wall  11  to the above-mentioned non-deformed configuration of the wall  11 . The first elastic return movement may be in a snap-on fashion. 
     In this way, when the glass B is in the inserted position, the wall  11  tends elastically to adopt the non-deformed configuration. 
     A user can make the glass B to move from the non-inserted position to the inserted position, exerting on the glass B and on the wall  11  a suitable system of forces which contrasts the elastic resistance which the wall  11  opposes to the above mentioned first passage of the glass through the opening  11   a.    
     These structural features of the above mentioned at least one material are such that the wall  11  tends to elastically move towards and/or maintain its non-deformed configuration. 
     When the wall  11  adopts the fitting condition, the wall  11 , by means of the shape of the wall  11  in the non-deformed configuration and/or by means of the structural features of the above-mentioned at least one material of the wall  11 , exerts a locking action on the glass B. The locking action keeps the glass B in the inserted position. From another point of view, the glass B also exerts the locking action on the wall  11 , and ensures that the wall  11  remains in the fitting condition. The fitting condition of fitting the wall  11  corresponds in effect to the inserted position of the glass B. The locking action can be considered as a gripping or retaining action exchanged between the wall  11  and the glass B. 
     The shape of the wall  11  in its non-deformed configuration is such that the wall  11 , when it adopts the fitting condition, at least partly surrounds the said at least a part of the glass B. 
     The wall  11 , by means of the structural features of the above mentioned at least one material, is elastically deformable in order to be able to adopt a second deformed configuration. The second deformed configuration is not shown in the accompanying drawings. When the wall  11  adopts the second deformed configuration, the wall  11  allows the above mentioned second passage of the glass B through the opening  11   a.    
     The wall  11  is configured, when the glass B has been subjected to the second passage and adopts the not inserted position, to be subjected to a second elastic return movement. The second elastic return movement of the wall  11  is a movement of the wall  11  from the second deformed configuration of the wall  2  towards the non-deformed configuration of the wall  11 . The second elastic return movement may be a movement of the wall  11  from the above-mentioned second deformed configuration of the wall  11  to the above-mentioned non-deformed configuration of the wall  11 . The second elastic return movement may be in a snap-on fashion. 
     In this way, when the glass B adopts the not inserted position, the wall  11  adopts the non-deformed configuration. 
     In this way, when the wall  11  adopts the not fitting condition, the wall  11  stably adopts the non-deformed configuration. 
     A user can make the glass B to move from the inserted position to the not inserted position, exerting on the glass B and on the wall  11  a suitable system of forces which contrasts the elastic resistance which the wall  11  opposes to the above mentioned second passage of the glass B. 
     The first deformed configuration could be similar or coincident with the second deformed configuration. In this case, the first elastic return movement is similar or equal to the second elastic return movement. 
     The glass B defines an axis Z of the glass B. 
     The Z axis might be an axis of symmetry of the glass B. 
     The glass B has an outer surface  10  of the glass B. The outer surface  10  of the glass B can be considered as a lateral outer surface  10  of the glass B. 
     The outer shape of the above-mentioned at least a part of the glass B is defined by at least a part of the outer surface  10 . 
     The above-mentioned outer surface  10  of the glass B has a longitudinal extension along the axis Z of the glass B. In this application, the fact that any object has a longitudinal extension along a predetermined axis means that it is possible to define an extension of the respective object along a direction parallel to the predetermined axis. The above-mentioned outer surface  10  of the glass B has an angular extension about the axis Z of the glass B. In this application, the fact that any object has an angular extension about a predetermined axis means that it is possible to define an extension of the respective object along a curve situated around the predetermined axis. 
     The wall  11  of the cover  1  defines a longitudinal axis X. The wall  11  has a longitudinal extension along the longitudinal axis X. The wall  11  has an angular extension about the longitudinal axis X. 
     The longitudinal axis X, when the glass B adopts the inserted position, coincides with the axis Z of the glass B. 
     The wall  11  of the cover  1  is shaped, along the above mentioned extensions of the wall  11 , in such a way that, when the glass B adopts the inserted position, the wall  11  coats the above-mentioned at least a part of the outside surface  10  of the glass. 
     The opening  11   a  of the wall  11  extends along a sector of the angular extension of the wall  11 . Thus, the opening  11   a  of the wall  11  can be considered as a lateral opening  11   a  of the wall  11 . This sector of the angular extension of the wall  11  is positioned in such a way that the opening  11   a  leaves uncovered and/or uncoated, when the glass B adopts the inserted position, a corresponding sector  10   a  of the angular extension of the outer surface  10  of the glass B. 
     The lateral opening  11   a  extends along the entire above-mentioned longitudinal extension of the wall  11 .

     The above mentioned first passage and second passage of the glass B through the opening  11   a  comprises respectively a first passage and a second passage of said at least a part of the base B 3  through the opening  113   a  of the disc portion  113 . 
     When the glass B adopts the inserted position in the cavity  110 , the wall  11  is able to keep oneself in the fitting condition. This is thanks to the shape of the wall  11  and/or the structural features in terms of rigidity/flexibility of the at least one thermally insulating material with which the wall  11  is made. The wall  11  is able to keep oneself in the fitting condition thanks also to the fact that the return elasticity of the wall  11  is such that the sleeve portion  112  exerts a first pressure action and/or a second pressure action. The first pressure action is exerted by the sleeve portion  112  on the cup-shaped portion  111 . The first pressure action is exerted in opposition to the cup-shaped body B 1 , in the sense that the first pressure action presses at least partly the cup-shaped portion  111  against the cup-shaped body B 1  of the glass B. The second pressure action is exerted by the sleeve portion  112  on the disc portion  113 . The second pressure action is applied in opposition to the base B 3 , in the sense that the second pressure action presses at least partly the disc portion  113  against the base B 3  of the glass B. 
     The first pressure action and the second pressure action may be considered part of the above-mentioned locking action which is exchanged between the glass B and the wall  11 , when the wall  11  adopts the above-mentioned fitting condition. 
     The main direction of the first pressure action is indicated by the first arrow F 1  of  FIG. 11 . The main direction of the second pressure action is indicated by the second arrow F 2  of  FIG. 11 . 
     In order for the wall  11  to adopt the above-mentioned fitting condition, the cup-shaped portion  111  is pressed against the cup-shaped body B 1  of the glass B until the above-mentioned at least a part of the cup-shaped body B 1  enters at least partly in the above mentioned first part of the cavity  110  defined by the cup shaped portion  111 . 
     The user then presses the sleeve portion  112  against the stem B 2  of the glass B until all the above-mentioned at least a part of the cup-shaped body B 1  is totally inside the above-mentioned first part of the cavity  110 , and until the above-mentioned at least a part of the stem B 2  is totally inside the above-mentioned second part of the cavity  110 . 
     At this point the wall  11  has adopted the fitting condition. 
     The locking action exchanged between the wall  11  and the glass B in the fitting condition of the wall  11  preferably also prevents a possible rotation of the wall  11  relative to the glass B and about the axis of the glass Z, which in this fitting condition coincides with the longitudinal axis X of the wall  11 . 
     Any machining tolerances of the wall  11  and/or of the glass B could reduce the locking action exchanged between the wall  11  and the glass B. For this reason, the cover  11  might comprise at least one additional elastic element which, when the wall adopts the fitting condition, is interposed between the wall  11  and the glass B. 
       FIG. 14  shows a longitudinal cross section of a possible further embodiment of cover in accordance with the invention. The further embodiment is indicated by numeral  1 ′. In this further embodiment, the cover  1 ′ comprises at least one first elastic element K 1 . The first elastic element K 1 , when the wall  11  adopts the fitting condition, is interposed between the disc portion  113  and the base B 3  of the glass B. In this further embodiment, the cover  1 ′ comprises a second elastic element K 2 . The second elastic element K 2 , when the wall  11  adopts the fitting condition, is interposed between a transition area of the wall  11  and a transition area of the glass B. The transition area of the wall  11  is a transition area between the sleeve portion  112  and the cup-shaped portion  111 . The transition area of the glass B is a transition area between the stem B 2  and the cup-shaped body B 1  of the glass B. 
     The first elastic element K 1  and/or the second elastic element K 2  might be a seal and/or be at least partly annular in shape. The first elastic element K 1  and/or the second elastic element K 2  might be made, for example, of silicone. 
       FIG. 14 a    shows an enlargement of the area where the first elastic element K 1  is situated.  FIG. 14 a    shows that the first elastic element K 1  is interposed between the disc portion  113  of the wall  11  and the base B 3  of the glass B. 
       FIG. 14 b    shows an enlargement of the area where the second elastic element K 2  is situated.  FIG. 14 b    shows that the second elastic element K 2  is interposed between the above-mentioned transition area of the glass B and the above-mentioned transition area of the wall  11 . 
     The elastic elements K 1  and K 2  produce a “precise elasticity” of the cover  1  at predetermined points of the wall  11 , whilst the structural features of the above-mentioned at least one material of the wall  11  result in a “distributed elasticity” of the cover  1 . 
     The additional elastic elements render more secure the seal of the wall  11  on the glass B, increasing the above-mentioned locking action exchanged between glass B and the wall  11 , for example in order to compensate for machining tolerances and/or imprecisions of the wall  11  and/or of the glass B, which could determine, when the wall  11  adopts the fitting condition, excessive clearances between the wall  11  and the glass B. 
     In this fitting condition of the wall  11 , the wall  11  covers at least partly the glass and, through the above-mentioned characteristics in terms of thermal insulation of the above-mentioned at least one material, allows an at least partial (or total) thermal insulation of the drink contained in the glass. In this fitting condition of the wall  11 , the wall  11  covers at least partly the glass and defines, by its shape, also a grip for moving the glass B by the user, in such a way as to reduce, by means of the above-mentioned surface features of the at least one material, the above-mentioned problems due to the slipperiness of the grip of the glass B. The grip defined from the wall  11  is in particular defined by the cup-shaped portion  111  and/or, if necessary, at least partly also by the sleeve portion  112 . 
     Moreover, the wall  11 , by the shape of the wall  11  and the above-mentioned structural features of the at least one material, is able to remain stably in the fitting condition, without it being necessary to use additional retaining systems designed to retain the wall  11  in the fitting condition. Moreover, the wall  11 , by the shape of the wall  11  and the above-mentioned structural features of the at least one material, is able to remain stably in the fitting condition, also if the opening  11   a  of the wall, and in particular the first portion  111   a  of the opening  11   a , is relatively large. 
     In this way, considering that the glass B could be at least partly or totally transparent, the opening  11   a  of the wall  11 , and in particular the first portion  111   a  of the opening  11   a , may be sufficiently large to allow the drink or beverage contained in the glass B to be seen, through the first portion  111   a  of the opening  11   a , whilst retaining the functionalities of thermal insulation and/or reduction of slipperiness as mentioned above. The opening  11   a  of the wall  11 , and in particular the first portion  111   a  of the opening  11   a , may be sufficiently large also to allow to see well a possible image printed on the outer surface  101  of the cup shaped body B 1 . 
     The cover  1  may be used on glasses for example in the form of a goblet, or on glasses of other types.
