Pouring Lid for Cans

Abstract

A pouring lid for cans of the type comprising a tubular body (10) having an annular upper wall (12) which presents an inner face (12b), an opening (13) and having any point of its inner face (12b) positioned at a height in the interior of the tubular body (10), at minimum equal to the height of another point of said inner face (12b) positioned radially externally. A pouring lid (20) is removably fitted and retained in the opening (13) and comprises a closing wall (21) provided with a median opening (21a) and externally carrying a tubular projection (27) generally provided with an obturator (30), any point in the inner face of the closing wall (21) of the pouring lid (20), when mounted to the can, being positioned at a height, measured in the interior of the tubular body (10), at minimum equal to the height of any other point of the inner face (12b) of the annular upper wall (12).

Description

FIELD OF THE INVENTION[0001]The present invention refers to a pouring lid to be applied to a can generally formed in metallic sheet and presenting a polygonal or circular cross section and being provided with an end upper lid of the type which allows multiple opening and closing operations during the progressive consumption of the bulk product stored in the can in a particulate or liquid form.PRIOR ART[0002]The cans of the type considered herein are generally those described in Brazilian patent application PI0306608-8 of the same applicant and comprising a tubular body formed by one or more peripheral sidewalls, to whose lower edge is double seamed or otherwise incorporated a bottom wall, and to whose upper edge is double seamed or otherwise affixed the outer peripheral edge of an upper annular wall, having an inner peripheral edge that defines a median opening to access the interior of the recipient and in which is configured a seat onto which will be seated and retained a reclosab...

AI Technical Summary

Benefits of technology

"The present invention provides a pouring lid for cans of bulk products that allows for controllable and directional release of the product through the opening in the can. The lid includes a closing wall with a median opening and a tubular projection aligned with the opening. The lid can be fitted into the can without creating any obstacles to the flow of the product. The tubular projection can also have an obturator for continued storage of the product after the original closing lid has been replaced. The invention prevents any obstacles to the free radial flow of the stored product and allows for the continued use of the can."

Problems solved by technology

Said prior patent application PI0306608-8 of the same applicant comments the known difficulty the user has to pour out the whole bulk product contained in this type of can provided with an annular upper wall, in which it is practically impossible or at least very laborious to extract all the product from the interior of the can by the simple gravitational effect.

Although the solution above allows the bulk product stored in the can to completely flow from within said can when the lid is removed and the recipient is inverted, there is a certain difficulty in providing a controlled and directed flow of the bulk product through the opening of the annular upper wall of the can, it being noted that the more critical the need to transfer the bulk product from the inside of the can to another specific place to receive a determined amount of said bulk material, the higher said difficulty, as it occurs when a certain amount of the particulate material is supplied to soap and detergent reservoirs of washing machines or when it is desired to transfer a relatively precise amount of the bulk material to recipients designed to contain single or reduced dosages.
