Definitions

  • the present invention refers to an improvement in the construction of cans, in which the annular upper wall is provided with a discharge opening, to be closed by a press fit lid, and which occupies a substantial part or practically the whole area of said upper wall.
  • the invention allows said can to be used for containing dangerous goods .
  • the tubular wall 14 which surrounds and defines the opening A, incorporates a continuous tubular rib 16 with a circular cross section and which is provided in a plane that is lowered in relation to the plane of the closing seat 13.
  • a lid 20 having a peripheral edge 21, usually defined by a tubular rim, which is outwardly downwardly bent and from which peripheral edge 21 is downwardly projected a circular lateral wall 22 provided with a peripheral recess 23, having an approximately semi-circular section, and which is dimensioned to be fitted around the continuous tubular rib 16 upon seating the lid 20 onto the opening A of the can.
  • the peripheral edge 21 is seated onto the closing seat 13 when the lid 20 is fitted onto the opening A.
  • FIGS 1 and 2 show two distinct constructions for the upper wall 11 of the can 10 produced according to the solution proposed in said prior art patent PI9408643-5. As it can be observed, the upper wall 11, in both configurations is not maintained flat until reaching the tubular wall 14 that surrounds the opening A, being upwardly (figure 1) or downwardly
  • the deformations of the upper wall 11 for the definition of the closing seat 13 are usually obtained by spinning and drawing the metallic sheet, reducing, in the deformed regions, the thickness of the sheet, and consequently the resistance thereof.
  • These cans already belonging to the state of the art are not resistant enough to meet the requirements of the international and national regulations regarding shipping of dangerous goods.
  • the lids are retained only by attrition, they are easily released from the can when the internal pressure of the can is increased to values slightly higher than the atmospheric pressure. Even in the case of the lids illustrated in figures 1 and 2, which are provided with mechanical locking, when the can is submitted to expected internal pressures, the upper ring is deformed inside out, expelling the lid.
  • the object of the present invention is to provide a can having an annular upper wall, which surrounds the discharge opening, to be closed by a press fit lid, and which is constructed to give the can enough structural resistance, in order to comply with the requirements imposed to these type of containers designed for dangerous goods. Disclosure of the Invention The object mentioned above is attained by providing a can for dangerous goods, having an upper wall provided with an external peripheral portion, which is double seamed to the lateral wall; a median portion with a larger radial extension, and an internal peripheral portion, defining a closing seat and from which depends a tubular wall defining a discharge opening and incorporating, internally, a tubular rib, onto which will be fitted a peripheral recess of a lid having a peripheral edge to be seated onto said closing seat.
  • the internal peripheral portion and the median portion of the upper wall are mutually coplanar, one being the radial extension of the other.
  • Figure 1 is a partial cross-sectional view of the upper wall of a can provided with a lid and constructed according to a possible embodiment of the prior art
  • Figure 2 is a similar view to that of figure 1, but illustrating a can constructed according to another embodiment of the prior art ;
  • Figure 3 is a similar view to those of figures 1 and 2, but illustrating a can constructed according to an embodiment of the present invention.
  • Figure 4 is a similar view to that of figure 3, but illustrating another embodiment of the present invention.
  • the present can comprises a generally cylindrical lateral wall 10, and an upper wall 11 having: an external peripheral portion 11a, which is conventionally double seamed to an end edge of the lateral wall 10; a median portion lib with a larger radial extension; and an internal peripheral portion lie, into which is incorporated and from which depends a tubular wall 14, defining a discharge opening A.
  • a closing seat 13 which is formed by spinning applied to said internal peripheral portion lie, causing said internal peripheral portion lie and said closing seat 13 defined thereby to occupy a level that is superior to the plane containing the median portion lib.
  • the spinning of the internal peripheral portion lie forms a continuous circular projection, whose cross section has the shape of an open and inverted "V" with a rounded vertex, and which defines the closing seat 13, and with the inner lateral leg extending downwardly, in order to define the tubular wall 14.
  • V open and inverted
  • the upper wall 11 develops from the external peripheral portion 11a until reaching the region of the closing seat 13, in a single plane orthogonal to the axis of the can.
  • the deformation of the internal peripheral portion lie of the upper wall 11, upwardly in the region of the closing seat 13, is usually obtained by spinning, weakening the regions presenting plane change close to said closing seat 13 , and causing the latter to collapse when the can is submitted to determined efforts due to internal pressure.
  • the upper wall 11 of the can has its median portion lib occupying a substantial part of the radial extension of said upper wall 11, provided in a plane that is slightly elevated in relation to the external peripheral portion 11a, having a small radial extension and which is double seamed to the lateral wall 10 of the can.
  • the elevation of the median portion lib of the upper wall 11 is desirable to obtain a corresponding gain in the volumetric capacity of the can.
  • the closing seat 13 is formed by lowering the internal peripheral portion lie of the upper wall 11, which lowering is obtained by spinning and drawing the metallic sheet, weakening the can is this region, as already mentioned in relation to the embodiment of figure 1.
  • the closing seat 13 is defined by an internal peripheral portion lie, which is coplanar to the median portion lib of the upper wall 11.
  • the new construction proposed by the present invention allows to eliminate, from the upper wall 11, the regions thereof deformed by spinning, in order to define the closing seat 13 in a plane different from that containing the median portion lib of the upper wall 11.
  • the upper wall 11 has its median portion lib and internal peripheral portion lie contained in the same plane, which is slightly elevated in relation to the external peripheral portion 11a, leading to a corresponding gain in the volumetric capacity of the can. It should be understood that the upper wall 11 may be formed with its external peripheral portion 11a, median portion lib, and internal peripheral portion lie entirely contained in a single plane, extending from the lateral wall of the can, up to the region in which is defined the closing seat 13 and from which depends the tubular wall 14, as illustrated in figure 4.
  • the deformations produced in the upper wall 11, in order to elevate the median portion lib and the internal peripheral portion lie in relation to the external peripheral portion 11a, have small values and are located at small radial distances from the elevated wall 10, producing no relevant structural weakening in the can, as it occurs with the deformations existing in the known solutions, in which the closing seat is defined in planes provided above or below the plane that contains the median portion lib and the internal peripheral portion lie of the upper wall 11 of the can.
