Definitions

  • This disclosure relates to a can of the easy opening type wherein one end of the can has a major portion of the end panel thereof in the form of a removable panel portion.
  • the can body is divided immediately adjacent the one end of the can with an inwardly projecting guard bead which underlies the end panel of the can end and projects radially inwardly of the boundaries of the removable panel portion so as to protect one dispensing a product from the can from engaging the resultant raw edge when the removable panel portion is removed.
  • the can is provided with a snap-on type plastic overcap.
  • the overcap in addition to protecting the contents of the can after the can has been opened, also protects the can end against accidental rupture prior to the initial opening thereof.
  • the guard head is advantageously utilized in conjunction with the overcap in that it provides clearance for engaging the lower edge of the overcap to facilitate the removal of the overcap.
  • the guard bead has a further function in that it reinforces the entire end construction of the can and thereby further eliminates the possibility of accidental rupture of the end panel.
  • This invention relates in general to new and useful improvements in can constructions, and more particularly to a novel can of the easy opening type wherein the can body thereof is provided immediately adjacent the easy Opening end thereof with a guard bead.
  • a guard bead is provided in the can body immediately below the end panel of the can end, the guard bead being a flattened bead which projects into the can body radially inwardly of the weakening line defining the removable panel portion of the can end and at the same time occupies a minimum portion of the volume of the can body.
  • Another object of this invention is to provide a can body adjacent an end portion thereof particularly adapted to have secured thereto by seaming an end of the easy opening type, with a readily collapsible head which may be collapsed by applying an axial pressure on the opposite ends of the can body either before or after the can end has been secured thereto.
  • Another object of this invention is to provide a novel can body being formed adjacent an end portion thereof with a bead which may be readily formed by a normal bead forming operation and is readily collapsible by the application of an endwise pressure on the can body so as to be relatively fiat as compared to normally formed beads.
  • Another object of this invention is to provide a novel can construction which includes a can body having seamed to one end thereof an easy opening can end of the type having an end panel formed with a weakening line defining a removable panel portion, and the can body having formed therein immediately adjacent the can end a fiat bead which projects radially inwardly of the can body and has a wall portion disposed immediately adjacent the end panel, the bead being a guard bead and both reinforcing the can body and the can end and forming a guard against accidental engagement with the raw edge which results when the removable panel portion is removed.
  • a further object of this invention is to provide a novel can construction which includes a can body having an easy opening can end secured thereto, the can body being provided with a combination reinforcing and guard bead immediately adjacent the can end, and there being provided an overcap which normally overlies the can end and is engaged with the double seam, the overcap having a skirt which terminates immediately adjacent the bead whereby the space provided by the bead facilitates the engagement of the skirt of the overcap and the removal of the overcap.
  • the overcap has an end panel overlying the end panel of the can end and affording protection against engagement of the end panel by another object to the extent that accidental rupture of the end panel would occur.
  • the guard bead reinforces the double seam between the can body and the can end and thereby stifIens the end portion of the can and aids in the prevention of accidental rupture of the end panel of the can end.
  • FIGURE 1 is an exploded perspective view of a can body and can end formed in accordance with this invention and shows the two generally before they are assembled.
  • FIGURE 2 is an enlarged fragmentary vertical sectional view taken through an end portion of the can body with the can end double seamed thereto and prior to the collapsing of the bead of the can body.
  • FIGURE 3 is an enlarged fragmentary longitudinal sectional view taken through one end of a completed can body formed in accordance with this invention and provided with an overcap.
  • FIGURE 4 is a schematic view illustrating the advantages of the Hat guard bead of this invention as compared to a conventional type of head of a size necessary to perform the same function.
  • FIGURE 3 the can construction which is generally referred to by the numeral 5 and includes a can body 6 having secured thereto by means of a conventional double seam 7 an easy opening can end which is generally referred to by the numeral 8.
  • the can 5 is also provided with an overcap, which is generally referred to by the numeral 9.
  • the can end 8 is of a conventional easy opening construction and includes an end panel 10 of which a major portion thereof is in the form of a removable panel 11 defined by a circumferential weakening line 12. It is to be understood that the removable panel 11 will be provided with suitable means, such as a pull tab (not shown), for facilitating the removal thereof without the use of any tools.
  • the can body 6 is provided with a head 14 which is disposed immediately adjacent the seam 7 and the end panel 10.
  • the bead 14 is U-shaped in cross section and includes two walls 15 and 16 which are disposed generally normal to the axis of the can body 6 and are connected together by a bight 17. It is to be noted that the wall 15, which is the uppermost of the two walls, is disposed in direct underlying relation to the end panel 10 and will be disposed closely adjacent the same.
  • the head 14 is extremely flat as compared to the bead 13, as is evident from FIGURE 4, it will be seen that it may effectively protect or guard the raw edge which results when the panel 11 is torn along the weakening line 12 without the bead greatly projecting into the can body 6 or occupying a material volume thereof.
  • the bead 14 has a relatively great beam strength in a radial direction and therefore, greatly stilfens the can 5 in the area of the can end 8.
  • the head 14 projects inwardly of the can body 6 until the bight 17 is disposed generally tangent to a line 18 which extends from the inner top portion of the seam 7 through. the weakening line 12.
  • the head 14 due to its particular configuration and relative depth as compared to height, cannot be formed in a conventional manner. It is, therefore, necessary to provide the can body 6 first with a head, which is generally identified by the numeral 20, as is shown in FIGURE 2.
  • the head 20 is generally V- shaped in cross section and is formed of two radially inwardly converging walls 21 and 22 connected together by an arcuate portion 23.
  • the bead 20 may be formed with any conventional bead forming operation after the can body 6 has been formed.
  • an endwise compressive force is applied to the can body 6 as is generally indicated by the arrows 24, 25 in FIGURE 2. This endwise compressive force results in the collapsing of the head 20 with the walls 21 and 22 swinging towards one another and the curve 23 tightening.
  • the head 14 has another advantageous function when the can 5 is provided with the overcap 9.
  • the overcap 9 has a skirt 27 which surrounds the seam 7 and which terminates in an inwardly directed retaining flange 2-8 at the lower edge thereof, the retaining flange 28 underlying the seam 7.
  • the head 14 provides suflicient clearance for one to engage the flange 28 with ones fingers in order to outwardly spread the lower portion of the skirt and release the overcap 9 from the can.
  • the overcap 9 has an end panel 29 which overlies the end panel 10 in spaced relation and which end panel 29, although the overcap 9 is formed of a flexible plastic material, is prevented from moving towards the end panel 10 sufiiciently to prevent any foreign object from accidentally striking the end panel 10 and efiecting the rupture thereof along the weakening line 12.
  • the overcap 9 cooperates with the bead 14 to increase the rigidity of the end portion of the can 5, thereby resisting accidental flexure of the end panel 10 and the rupture thereof along the weakening line 12 in the case of droppage.
  • a can construction of the type including a can body having one end closed by an easy opening can end having a removable panel portion defined by a Weakeing line formed in the end panel thereof, said can body having an end portion particularly adapted for the seaming of the can end thereto, said can body being provided immediately adjacent said end portion with an inwardly directed bead particularly adapted for reinforcing said can body and forming a guard relative to a raw edge formed when the removable end panel is removed, said head projecting radially inwardly beyond said weakening line substantially to a line extending from the extreme end of said can through said weakening line.
  • said head is a generally fiat bead of generally U-shaped section and includes an axially outermost wall disposed generally normal to the axis of said can body and closely underlying said end panel.
  • a can construction of the type including a can body having one end closed by an easy opening can end having a removable panel portion defined by a weakening line formed in the end panel thereof, said can body having an end portion particularly adapted for the seaming of the can end thereto, said can body being provided immediately adjacent said end portion with an inwardly di rected bead particularly adapted for reinforcing said can body and forming a guard relative to a raw edge formed when the removable end panel is removed, and a protective overcap having a skirt releasably interlocked with said seam and an end panel overlying said removable panel portion in spaced relation thereto and protecting said can end against accidental rupture.
  • a can body having one end closed by an easy opening can end including a removable panel portion defined by a weakening line formed in the end panel thereof, said can body having an end portion particularly adapted for the seaming of the can end thereto, said can body being provided immediately adjacent said end portion with an inwardly directed bead particularly adapted for reinforcing said can body and stiffening said can body end portion and said can end against undue fiexure which will result in the rupture of said end panel along said weaking line, and an overcap carried by said can body end portion, said overcap including an end panel and a depending skirt, said depending skirt surrounding the seam between said can end and said can body and terminating generally in alignment with said bead, and said overcap end panel being disposed in protective overlying spaced relation to said can end panel.
