Description

  The present invention is generally formed of a metal sheet and has a polygonal or circular cross section, and allows multiple opening and closing operations while gradual consumption of bulk product stored in particulate or liquid form in a can It is related with the pouring lid used for the can which provided the edge part top lid | cover of the kind to make.

  A can of the type contemplated herein includes a tubular body generally described in Brazilian patent application PI 0306608-8 by the same applicant and formed by one or more peripheral side walls, The lower edge is double spliced or incorporated into the bottom wall, and its upper edge is double spliced or fixed to the outer peripheral edge of the upper annular wall, defining a central opening to define the interior of the receiver A seat is constructed which has an inner peripheral edge for access to, can be seated on it and closed again, and holds a lid which can be made of metal sheet or plastic material.

  In many solutions of known can structures, the radial extension of the annular upper wall defined between its outer periphery and its inner periphery and having an opening to access the interior of the can includes a can When the is inverted, there is provided at least one peripheral region that also sits on the annular top wall of the can towards its opening and defines a barrier that impedes free radial gravitational flow of the bulk product. .

  The above-mentioned prior patent application PI 0306608-8 by the same applicant requires that the user pour out the entire bulk product contained in this type of can with an annular top wall, and simply by gravity effects inside the can Describes the well-known difficulty that it is practically impossible or very cumbersome to remove all products from the. It is stated that when the can is inverted after removing the lid, a small amount of product, whether powder, granule or liquid, tends to remain on the annular top wall.

  Due to the above-mentioned drawbacks, the solution proposed in the above-mentioned patent application No. PI 0306608-8 is that when the can is opened and inverted, the stored product adhering to the annular upper wall is radially opened by gravity. A can that can flow outward from the can toward the can.

  The above-mentioned patent application further provides a sheet on the annular upper wall of the can on which a lid is seated that can be opened and sealed multiple times as a product storage container during operation of the can.

  According to Applicant's prior structure proposal, the annular upper wall of the tubular body is adjacent to any point on its inner surface, measured radially inside the tubular body, radially outward with respect to this point. Arranged at a height that is at least equal to the height of other points on this inner surface.

  In the above structure, the annular upper wall of the can acts as a kind of hopper, and when the can is inverted, it directs the product toward the opening of the tubular body, and the flow of the product contained inside the tubular body of the can enable.

  The above solution allows the bulk product stored in the can to flow completely from the inside of the can when the lid is removed and the container is inverted, but the bulk through the annular top wall opening of the can. There are several difficulties in controlling and guiding the product flow, when a certain amount of particulate material is fed into the soap and detergent reservoirs of a washing machine, or a relatively accurate amount of bulk material is simply removed. When it is desired to transfer to a container designed to contain one or a small amount of use, the bulk product is transferred from the inside of the can to another specific location and a predetermined amount of the above bulk material It is noted that this difficulty is so high that the need to accept is important.

  Due to the above-mentioned drawbacks of the prior art regarding the direction and control of the bulk material discharged through the opening provided in the annular upper wall of the can, the present invention can be applied to the interior of the can when attached to the upper opening of the can. It has the overall object of providing a pour lid for the type of cans contemplated herein that allows the stored product to have a controllably directional release through the top opening. .
