Definitions

  • ABSTRACT [22] Filed: May 7, 1973 A two or three piece metal container is adapted to hold a pressurized product for dispensing through a pp N05 357,606 valve mounted on the container.
  • the container has a safety venting system therein, whereby the product 52 us.
  • CI. 220/89 A, 220/44 R 222/397 may he vented hem e filled Pressurized Container 51 lm.
  • the venting system comprises a plurality of triple scores formed in the seam where the container [56] References Cited body is joined to the top closure of the container.
  • the present invention relates generally to a metal aerosol container having a pressure relief system whereby the internal contents of the container may be vented therefrom when the internal pressure rises sufficiently to a level threatening blowing the top or bottom end off the container. More particularly this invention relates to a two or three piece metal aerosol container having a simple venting system to eliminate explosion of a filled aerosol container when the internal pressure rises considerably, which may be encountered during excessive heating of the container.
  • pressurized aerosol containers have been marketed to the general public. These containers usually comprise a three piece metal container having therein a product to be dispensed, together with a propellant that provides the internal pressure necessary to dispense the product through a valve mounted on the container. Products such as foods, cosmetics, insecticides, etc. have been packaged in these types of containers with considerable success.
  • Full cans will vent if excessive pressure develops in the can due to misuse. This might involve placing the can on a hot stove or radiator, near a hot iron, or in the glove box, trunk, or window of a car sitting out in the sun.
  • partially filled cans will also vent under the conditions mentioned above; however, near-empty cans may fail at the side seam in typical three piece metal cans before the pressure required to activate the safety feature is generated under prolonged exposure to intense heat.
  • Aerosol cans which are considered empty or nearly empty usually contains a small amount of residual product and propellant. These small amounts are sometimes not sufficient to generate the pressure needed to activate the safety feature when the can is incinerated. Under the intenseheat of incineration, some of these cans will vent or rupture at the side seam of a three piece can. This is due to the fact that the side seam is adhered with a solder or relatively low temperature material. This side seam rupture will occur at pressures below the pressure required to buckle the top closure and thus form the safety venting feature. This failure, although dangerous, is less violent than blow-off of the top or bottom end.
  • the relief concept must allow function of the container under controllable use conditions in violation of precautionary labeling so long as the temperature does not exceed 250 F for approximately one hour. At temperatures below 250 F, the time of exposure can be significantly increased.
  • a secondary type of failure encountered when internal pressure increases over the maximum allowable by the three-piece container construction is a side seam rupture, described above, which generally results from exposure to high temperatures.
  • the side seam failure is dependent upon exposure temperature, the position of the container with respect to the heat source, the type of product and propellant packed in the container, the quantity of product and propellant remaining in the container, and the container size.
  • the relief mechanism must be capable of releasing l4 cubic feet per minute of internal gas at 200 psig. Less release capacity is required for smaller containers as vent capacity is strictly dependent upon volumetric capacity.
  • the instant invention provides an improvement for safely venting excessive internal pressure in a pressurized aerosol dispenser container having a tubular body closed at one end and a metal end wall closing the other end, the end wall being secured to the tubular body by an annular convoluted seam, comprising: a plurality of venting scores, and an anti-fracture score flanking each side of each of said venting scores, said venting and anti-fracture scores penetrating partially through the metal of the end wall and extending from at least a portion of the most interior layer of the seam to the top portion of the seam, whereby when the internal pressure within the container increases and threatens to cause rupture of said container, the end wall will buckle outwardly causing the residual of said venting scores to fracture to thereby produce a plurality of vents to permit the pressurized contents to escape safely therethrough.
  • FIG. 1 is a side elevational view of a three-piece metal container utilized to dispense pressurized products.
  • FIG. 2 is a top plan view of the container of FIG. 1.
  • FIG. 3 is an enlarged, partial, sectional view showing the periphery of the dome and the container body prior to their being seamed together in forming of the container.
  • FIG. 4 is an enlarged, sectional view taken substantially along the line 4-4 in FIG. 3.
  • FIG. 5 is an enlarged, fragmentary, sectional view of the double seam formed by the periphery of the dome and the top of the container body.
  • FIG. 6 is an enlarged, fragmentary, side elevational view of the seam shown in FIG. 5 more fully illustrating the triple score.
  • FIG. 7 is an enlarged, partial, section view similar to FIG. 5 but illustrating the vent score on the interior of the periphery of the dome.
  • FIG. 8 is an enlarged, fragmentary, sectional view illustrating the periphery of the dome after high internal pressure has buckled the head and fractured the vent score to form a safety pressure relief vent.
  • FIG. 9 is an enlarged, fragmentary, side elevational view illustrating the ruptured score after buckling of the dome.
  • FIGS. 1 and 2. show a container, generally designated 12, comprising a tubular metal body 14 having a side seam 15.
  • the side seam 15 is generally sealed with solder, as is well known in the art, although it may also be welded.
  • Closing the bottom of the container is an end 16 hermetically seamed to the bottom of the body 14 by a seam 18.
  • a dome 20 is seamed to the top of the body 12 by an annular, convoluted, double seam (five layers of interfolded material) 22.
  • the upper end of the dome 20 has an orifice 23 defined by a top curl 24.
  • a valve cup is placed into the orifice 23 and a suitable dispensing valve, also not shown, is positioned within the valve cup to seal the container 12 and to permit dispensing of the product and propellant from the container 12.
  • a plurality of radial venting scores 26 are formed, preferably with a scoring punch when the dome 20 is flat, in the periphery of the dome 20 in the area that is to be the top of the double seam 22.
  • the scores 26 are narrow grooves formed in the periphery of the dome 20 and penetrate only partially through the metal of the dome 20.
  • a score 26 has a depth of approximately 0.009 inch for a total metal thickness of 0.014 inch, leaving a solid-metal residual 30 of 0.005 inch.
  • the developed length of the score is approximately 0.125 inch.
  • the included angle of the venting score 26 is approximately 60 and it is desirable that this angle not be below 40.
  • the bottom 28 of the venting score 26 is essentially flat in cross sectional appearance. This provides greater integrity and prevents premature cracking through the residual 30 of the material which would result in leakage of product and propellant from the container 12.
  • each of the venting scores 26 is flanked by a pair of shallower antifracture scores 27 having a depth of approximately 0.005 inch for the total metal thickness of 0.014 inch, leaving a solid metal residual 31 of 0.009 inch.
  • the most effective differential in score depths irrespective of the score depths is on the order of about 3 mils.
  • the developed length of the antifracture scores 27 is about the same as the developed length of the venting score 26, approximately 0.125 inch.
  • the included angle of the anti-fracture scores 27 is approximately 70 and it is desirable that this angle not be less than 40.
  • the bottom 33 of the anti-fracture scores 27 is essentially flat.
  • the center-tocenter spacing between the vent score 26 and each of the anti-fracture scores is approximately 60 mils, with a preferred range being between 50 and 70 mils.
  • the dome 20 prior to double seaming, has a corrugation 34 adjacent the seam area connecting the top of the body 14 with the dome 20.
  • the location of the venting score 26 is critical to the consistency of venting.
  • the venting score 26 must extend from at least a portion of the most interior layer which fits within a curl 38 which forms the peripheral edge of the dome 20.
  • the flange 36 is interfolded with the curl 38 to hermetically seal and close the container 12 as the double seam 22 is formed.
  • a small amount of sealing compound 40 is positioned along the interior wall of the curl 38 to provide a hermetic seal in forming the double seam 22.
  • a similar type of double seam may be used to form the seam 18 at the bottom of the container 12.
  • a plurality of radial venting scores 42 and anti-fracture scores are formed on the interior of the periphery of the dome 20.
  • the scores are hidden by being entirely within the double seam 22. In certain instances this has aesthetic advantages in that the multiplicity of scores are not seen by the user as are the exterior scores.
  • either type of scoring will function in the manner described hereinafter to provide a pressure relief system for a filled container 12.
  • a plurality of radial venting scores 26 have been formed in the double seam 22. This is to insure that no matter where the dome 20 begins buckling due to increased internal pressure, a vent 44 will be formed almost immediately and as the buckling continues about the periphery of the dome 20 additional vents 44 will form about the periphery of the dome 20 as additional radial venting scores 26 are deformed and fractured.
  • the experimental objective was to de- SCORE RESIDUAL (MILS) fine, with the use of graphs, the maximum possible score residual at which score fracture would occur after seaming the end to the can body to give commercially consistent venting, and the minimum possible TRIPLE SCORE MIN. RESIDUAL score residual which would not fracture prematurely, for both single and triple scores for the two different steel plates.
  • a pressurized aerosol dispenser container having a tubular body closed at one end and a metal end wall closing the other end, the end wall being secured to the tubular body by an annular convoluted seam
  • the improvement for safely venting excessive internal pressure comprising: a plurality of venting scores, and an anti-fracture score flanking each side of each of said venting scores, said venting and anti-fracture scores penetrating partially through the metal of the end wall and extending from at least a portion of the most interior layer of the seam to the top portion of the seam, whereby when the internal pressure within the container increases and threatens to cause rupture of said container, the end wall will buckle outwardly causing the residual of said venting scores to fracture to thereby produce a plurality of vents to permit the pressurized contents to escape safely therethrough.
  • tubular body is metal and the anti-fracture scores are shallower than the venting score.
