Liquid container

Abstract

A solution for a logistical problem within the beverage industry, specifically related to hot beverages such as coffee and tea; namely, storing the means to sell the beverages, which generally includes a cup, a lid for the cup, and an insulation sleeve that allows holding the cup in a comfortable way for the consumer, avoiding burns due to the high temperatures of the liquid. Thus, the container presented here unifies the 3 elements, comprising a body formed by a base and a wall, where the upper edge of said container has a group of flaps that in their closed position enables liquid containment and prevents spillage in case the container is moved, and through a modification in the cross profile of the wall. Additionally, the container has an insulation sleeve that keeps the contact surface at a low temperature.

I claim: 
     
         1 . A liquid container, comprising:
 a base;   a wall joined to the base; and   several flaps joined to the upper edge of the container in such a way that when they close, the mouth of the container formed by the base and the wall is covered;   characterized in that the wall joined to the base has a circular profile in its lower edge which modifies its geometry up to a polygonal profile in its upper edge, where the sides of the polygonal profile are the junction point between the wall and the flaps; and   the overlap of the flaps in closed position forms several sealing points, where one of the vertices of the polygonal profiles includes a first cut in one internal flap and a second cut in one external flap, in a manner that when the flaps are closed an opening for pouring is formed enabling the extraction of the liquid from the container.   
     
     
         2 . A liquid container according to claim number  1 , wherein the wall is joined to the base in a perpendicular manner, where the joint angle is equal or greater than 90°. 
     
     
         3 . A liquid container according to claim number  1 , wherein the polygonal profile is a rectangular profile. 
     
     
         4 . A liquid container according to claim number  1 , wherein one of the vertices of the polygonal profile is slightly rounded concurring with the opening for pouring. 
     
     
         5 . A liquid container according to claim number  1 , wherein the group of flaps includes at least one pair of internal flaps and one pair of external flaps. 
     
     
         6 . A liquid container according to claim number  5 , wherein the internal flaps close by total or partial overlapping. 
     
     
         7 . A liquid container according to claim number  6 , wherein the overlapping of the internal flaps is a partial overlap between protruding sections of both flaps, where the configuration of each internal flap includes a first edge joined to the upper edge of the container, where a surface extends toward the center covering half of the mouth of the container, including also in said surface an additional portion with a width equal to half the width of the first edge and enough length to overlap the flaps and keep them in horizontal position. 
     
     
         8 . A liquid container according to claim number  5 , wherein the external flaps close by total or partial overlapping, where said external flaps also include means to ensure their closed position. 
     
     
         9 . A liquid container according to claim number  8 , wherein the means ensuring the closed position include a tab that extends from the surface of one of the flaps, with form and size consistent with a slot made in the surface of the opposite flap. 
     
     
         10 . A liquid container according to claim number  1 , wherein all the flaps include at least one bend that, in their closed position, enables each flap to overlap with the adjacent flaps in their edges joined to the upper edge of the container, and generates a sealing point in each one of the vertices of the polygonal profile. 
     
     
         11 . A liquid container according to claim number  10 , wherein the bend is located a short distance from the edge in a way that keeps the flap in position in the upper part of the container, forming a step between the upper edge of the container and horizontal to the surface of said flap. 
     
     
         12 . A liquid container, comprising:
 a base;   a wall joined to the base; and   several flaps joined to the upper edge of the container in a way that when they close, the mouth of the container, formed by the base and the wall, is covered;   characterized in that the wall joined to the base has a circular profile in its lower edge that modifies its geometry up to a polygonal profile in its upper edge;   it includes a layer of insulation joined to the wall, which in turn includes a sleeve joined with glue to the wall of the container, where the geometry of the sleeve imitates the form of the base's circular profile and additionally is transformed in a polygonal profile as the height of the wall continues upward, forming a parallel layer to the wall of the container, where the edges of the polygonal profile of the sleeve becomes the junction point between the sleeve and the flaps;   the glue, due to its volume and application, generates air gaps between the wall and the sleeve which make up a thermal insulation layer; and   the overlap of the flaps in closed position make up several junction points, where one of the vertices of the polygonal profile comprises a first cut in an internal flap and a second cut in an external flap, so that when the flaps are in the closed position an opening for pouring is formed enabling the extraction of liquid from the container.   
     
     
         13 . A liquid container according to claim number  12 , wherein the wall is joined to the base in a perpendicular way, where the joint angle is equal or greater than 90°. 
     
     
         14 . A liquid container according to claim number  12 , wherein the polygonal profile is a rectangular profile. 
     
     
         15 . A liquid container according to claim number  12 , wherein one of the vertices of the polygonal profile is slightly rounded matching with the opening for pouring. 
     
     
         16 . A liquid container according to claim number  12 , wherein the group of flaps comprises at least one pair of internal flaps and one pair of external flaps. 
     
     
         17 . A liquid container according to claim number  16 , wherein the internal flaps close by total or partial overlapping. 
     
     
         18 . A liquid container according to claim number  17 , wherein the overlap of the internal flaps is a partial overlap between protruding sections of both flaps, wherein the configuration of each internal flap comprises a first edge joined to the upper edge of the container, from where the surface extends toward the center covering half of the mouth of the container, including also in said surface an additional portion with a width equal to half the width of the first edge and enough length to enable overlapping the flaps and keep them in horizontal position. 
     
     
         19 . A liquid container according to claim number  16 , wherein the external flaps close by total or partial overlap, wherein said external flaps also comprise the means to ensure a closed position. 
     
     
         20 . A liquid container according to claim number  19 , wherein the means that ensure the closed position is comprised of a tab that protrudes from the surface of one on the flaps, with a form and size consistent with the slot made in the surface of the opposite flap. 
     
     
         21 . A liquid container according to claim number  12 , wherein all flaps are comprised of at least one bend that, in their closed position, enables each flap to overlap with the adjacent flaps in their edges joined to the upper edge of the container, and generates a sealing point in each one of the vertices of the polygonal profile.
