Description

BEVERAGE CAN
The utility model relates to a container, particularly to a beverage can and might be used for containing of carbonated beverages, juices, etc.
As is know, beverage can [I]5 made mainly of sheet of metal, has a cylindrical part of side face and two end walls, one of which can be opened and the second one is not indented for opening, accordingly the first mentioned-above end wall is convex and domed in shape evenly protruded outward in an axial direction and is the bottom of the can, and the mentioned-above second end wall has mainly flat surface and folded seam formed at external circumference of the above-mentioned cylindrical part, connecting this part of the can with its side walls.
This beverage can has the disadvantage that when beverage is contained in the can for a long time, beverage organoleptic properties are not saved due to material a can is made of. As a result that beverage can is made of metal, oxidation of the contents of a container happens and consequently metal oxidation products migrate into the contents of a container. Besides, a can is sealed shut in such a way that a special tool is necessary for opening. Another disadvantage of the present technical solution is that as a result that a can is opaque, the contents can not be viewed and consequently it is not possible to define liquid level and color contained in a can as well as to determine liquid quality on appearance.
The most relevant can according to the declared technical solution is beverage can [2], comprising a cylindrical body with the bottom and open top with metal cover folded thereon, having a pouring opening closed with an opening tool, where a detachable plastic cover is installed on the said metal cover comprising a top and a skirt starting thereof, besides plastic cover is realized with dome-shaped top for repeated installation on a can after the said opening tool is opened.
However, the present technical solution has such disadvantage as changes of beverage organoleptic properties, when beverage is contained in a can for a long time, due to can metal body, which inner cavity is being filled with liquid (beverage) and consequently migration of metal oxidation products into the contents of a container happens, influencing on consumer's health harmfully. Besides, there happen dispensing of metal micro particles, released when a beverage can body integrity is broken. One more disadvantage of the present technical solution is that it is not possible to view the contents of a container because a can is opaque, not allowing to define liquid level and color contained in a can as well as to determine liquid quality on appearance.
The present utility model aims at creating of such a beverage can, which will allow to save organoleptic properties, when beverage is contained in a can for a long time, by improving of beverage can structure and using of a new material for a can body, also to ensure ecological safety and airtightness of a can, by lowering amount of metal, as well as to give more information about the contents in a can.
The assigned task is solved such that known beverage can comprising a cylindrical body with the bottom and open top with metal cover folded thereon, having a pouring opening closed with an opening tool, in accordance to the utility model, a can body is made of transparent material and having at least three side faces: bottom, middle and top face, interconnected together by means of grooves located on these faces horizontally, where bottom and top faces additionally comprising outer shell, which is fastened on the body by means of coupling of collar located around the perimeter of the outer shell and groove.
It is preferably that can body is made of polymeric material.
It is more preferably that polyethyleneterephthalate is used as polymeric material.
Besides, can body outer shell is made of metal.
Depth of the groove is 0.1 - 10 mm and width of the collar is 0.1 - 10 mm.
A beverage can body, being made of such material as, for example, polymeric material allows to lower amount of metal and at the same time to ensure ecological safety due to decreasing of oxides, which appear, when liquid is in contact with metal surfaces of a container. As a result, beverage organoleptic properties, when beverage is contained in a can for a long time, remain the same, and oxidation of the contents as well as migration of metal oxidation products into the contents of a container don't happen.
Furthermore, due to transparence of a container more information about the contents of a container is available and it is possible to determine liquid level and color contained in a can on appearance as well as visually become certain of the quality of the contents.
The outer shell, made, for example, of metal, being located on the bottom and top faces of a can additionally, fastened on a body of a can, ensures sufficient ruggedness of the construction in whole and increases its hardness.
The outer shell is fastened on a body by means of coupling of collar located around the perimeter of the outer shell and grooves located on side faces of a body horizontally, in such a case, that airtightness of a beverage can and firm connection of all parts thereof are ensured.
Depth of the grooves and width of the collar, set for coupling, being within the limits of 0.1 - 10 mm, are chosen experimentally and seem to be optimal for safe and airtight connection.
The utility model is described with reference to the accompanying drawings, wherein Fig. 1 is a prospective main view of a beverage can and Fig. 2 is a longitudinal section view of a beverage can.
A beverage can is made of transparent material, for example, of polymeric material, in particular of PET, comprising cylindrical body 1, divided into three interconnected transparent faces 2, 3, 4. A can body has hollow bottom 5 and convex cover 6 with opening tool 7 having pull tab. There is an outer shell 8 made, for example, of metal and located additionally on bottom face 4 and top face 2 of body 1. Besides, outer shell 8 is fastened on body 1 by means of coupling of collar 9, located around the perimeter of the outer shell and having width of 0.1 - 10 mm, and grooves 10 located on side faces of the body horizontally, having depth of 0.1 - 10 mm. This coupling ensures airtightness of a beverage can and firm connection of all parts thereof. Furthermore, a seam (fastener) 11 or other geometrical shape needed for a firm connection of can parts is implemented on the outer shell and on the top face of a body made of PET.
When manufacturing a beverage can, preforms of PET in intended color to ensure transparence are chosen, which then protect the contents of a container against exposure to light. Thereafter at press operation or later on a seam (fastener) or other geometrical shape needed for a firm connection of can parts is implemented on the outer shell. The process of connection of metal parts together with PET parts is realized at several stages. On the first stage PET preform of the container is heated in the infrared heating chamber, where temperature required for extending and blowing is reached. On the second stage metal parts of a can and the heated preform are placed in a special-purpose press tool. On the third stage preform is blown out in the press tool and then metal parts are connected with PET parts. Thanks to elasticity of PET, when being heated and pressed, polymeric parts of a container are connected with metal parts tightly, resulting in one integer product, which is a beverage can, comprising a cylindrical body with the bottom and open top. After a beverage can is filled with intended beverage, for example, with juice, beer or any other drink, the top section of a beverage can is folded with metal cover, having a pouring opening closed with an opening tool. Consequently, beverage organoleptic properties, when beverage is contained in a can for a long time, don't change as the inner surface of a can doesn't have any metal parts and the cover is coated with a special polymeric material.
As a result, the declared utility model allows to save organoleptic properties, when beverage is contained in a can for a long time, lower amount of metal due to can body being made of, for example, polymeric material, ensure airtightness of a can and ecological safety thanks to minimum contact of the contents of a container with metal surfaces of a can, as well as to give more information about the contents of a container due to transparent material used for a can.
