Definitions

  • This invention relates to a metal container for pressurised material and to a method of manufacturing the same.
  • a container of this type in the prior art, was mainly formed by the step of drawing raw material into a cylindrical body with an integral bottom and processing also the top part to be smaller in diameter for the mouth by so-called necking procedures, whereon the top is closed by another member equipped with valve apparatus in the final stage of the completion.
  • the metal container completed through the above procedures in the prior art is restricted in selecting the raw material, like aluminum, since it needs ductility and to be able to be easily cast. Further, the completed container is not strong enough for the pressure endurance because of the nature of the material itself.
  • US-A-4,241,844 discloses the following manufacturing method. Firstly there is provided a cylindrical body having its top end with a smaller diameter and its lower end open, i.e. with no integral bottom at all, and with the same diameter as the cylindrical body, and then fitting into the open end a disc-like bottom plate, produced by another step, finally securing the bottom plate in place by curling inwards the open end of the cylindrical body. The joint is sealed by the use of a polymeric varnish on the inner wall of the cylindrical body and optionally on the skirt part of the bottom plate.
  • This method allows the use of harder metallic material than aluminum, such as steel plate, and thus the cylindrical body is able to be made of steel plate as the said body is produced by means of the step with an open end.
  • Figures 1 and 2 herein show the construction and manufacture of another prior art metal container.
  • the cylinder 1 has its lower end open and its other end drawn into a smaller diameter top, where a dispensing means 24 such as a cap with an emitting valve is provided, the body between the ends being cylindrical.
  • the bottom plate 2 is inserted into the said open end of the cylinder 1 to form the lower closure of the cylinder 1, this bottom plate 2 being in the form of a disc with a dome-like top portion 22 and a depending cylindrical skirt portion 21.
  • Adhesive 3 is applied circumferentially to the inner surface of the cylinder 1 near its open end and, on assembly, forms a sealing joint part between the two components.
  • the lowest part of the cylinder 1 is subject to a curling operation and this folds over the skirt portion 21 of the bottom plate 2, whereon the skirt portion is pinched by the lowermost portion of the cylinder, to produce resistance against movement of bottom plate 2 out of the cylinder 1 as a result of inner pressure.
  • the adhesive does not almost exist correctly between the whole outer circumference of the bottom plate and the inner wall of the cylinder, and thus the sealing is only kept by the said semilunar-like collective group of the adhesive.
  • the effective surface of the adhesive which is to secure the whole outer circumference of the bottom plate with the inner wall becomes quite small, so that a desirable and satisfactory seal is not obtained.
  • a metal container comprising: a cylinder means adapted to be the main body of a container, the cylinder means having an open end; a bottom plate means having a dome-like top disc and a skirt portion, the skirt portion having its outer surface parallel or nearly in parallel with an inner surface of the cylinder means; a hardening adhesive securing said bottom plate means to said cylinder means; and a curling portion formed at said open end of the cylinder means so as tightly to attach the skirt portion of the bottom plate means to the cylinder means; characterised by gap means between said inner surface of the cylinder means and the outer surface of the skirt portion, and by said adhesive being effective in said gap means, and also along said inner surface of the cylinder means and said bottom plate means outside of said gap means.
  • a method of manufacturing a metal container comprising the steps of: providing a cylinder means adapted to be the main body of the container, the cylinder means having an open end; providing a bottom plate means having a dome-like top disc and a ski rt portion, the skirt portion having its outer surface parallel or nearly in parallel with an inner surface of the cylinder means; applying a hardening adhesive circumferentially to said inner surface of the cylinder means in the vicinity of its open end; inserting the bottom plate means into the cylinder means through the bottom end thereof; and curling said open end of the cylinder means towards the inside after the bottom plate means has been inserted into the cylinder means, to attach the skirt portion thereto; characterised by a step in which the adhesive on the inner surface of the cylinder means flows into gap means defined between said inner surface of the cylinder means and the outer surface of the skirt portion, and also along said inner surface of the cylinder means and said bottom plate outside of said gap means, effectively to secure the bottom plate to the cylinder means.
  • This invention is substantially based on the prior art construction shown in Figures 1 and 2 and aims to resolve the problems mentioned in connection therewith by increasing the adhesive effect between the cylinder and the bottom plate as well as improving the sealing of the container.
  • the cylinder 1 and the bottom plate 2 are generally the same as those of the prior art, and in the adhesive application step the adhesive is supplied circumferentially along the inner wall of the open end 11 of the cylinder 1.
  • a nozzle N of an adhesive container is placed at a defined portion of the inner wall of the cylinder 1 and runs at 150 rpm, for example, and the adhesive agent is, for example, dispersed at 18 c.c. per minute, the adhesive 3 being applied circumferentially along the inner wall of the open end 11 as shown in Figure 3.
  • the adhesive applied area must be the contacting area between the skirt portion 21 and the inner wall of the cylinder 1 when the bottom plate is fitted in the cylinder 1.
  • the bottom plate 2 is inserted into the cylinder body furnished with adhesive from the open end 11, and as shown in Figure 4, the bottom end of the skirt portion 21 and the open end 11 of the cylinder 1 become axially aligned, i.e. flush.
  • the adhesive 3 as shown in Figure 4 becomes a semilunar-like group around the periphery of the dome-like portion 22 of the bottom plate 2.
  • a gap is defined between the tapered surface and the inner surface of the cylinder, and adhesive is received therein, as shown in Figure 4.
  • the assembled body of the said cylinder 1 and the said bottom plate 2 is then placed upside down, and subject to a curling procedure as shown in Figures 5 and 6.
  • the curling method is similar to the prior art method, and during the curling step, the bottom plate 2 is forcibly pushed inwardly into the cylinder 1 as the open end portion 11 is bent to interfold the bottom plate 2.
  • the curling portion is formed circumferentially all around the bottom end of the skirt portion 21 as shown in Figure 6, and finally the said skirt portion 21 is pinched by the curling portions.
  • the following materials are available for forming the cylinder 1: steel plate, steel plate furnished with aluminium plating, aluminium sheet, cladding steel plate and compound steel plate furnished with plastics coating in its inside.
  • epoxy solvent agent such as epoxy-amine type, or epoxy-urethane adhesive with high-viscose quality.
  • the upper end of the skirt portion 21 is tapered as described and shown.
  • the skirt portion can alternatively be without any taper, as shown in Figure 8, having the hemispherical part 23, which is also easy and smooth to allow the said bottom plate 2 to be fitted into the cylinder 1.
  • the gap tolerance between the bottom end 11 of the cylinder and the skirt portion 21 is preferably between 0.1 and 0.3mm.
  • the skirt portion is equipped with taper, as shown in Figure 4, some small circumferential gaps are formed, into which the adhesive 3 flows. In other words, at least, on the upper part of the skirt portion, adhesive is accordingly provided.
  • the cylinder 1 is kept standing upside down, and the caulking is performed on the skirt portion 21.
  • the adhesive 3 runs down along the inner wall of the cylinder 1 from its semilunar-like group, and accordingly the said group of the adhesive 3 is gradually running lower and finally it changes its form into a convex style from its original concave style. Keeping this arrangement, the adhesive joint part is dried and the resultant cylinder 1 is surely jointed around the hemisphere of the bottom plate 2.
  • the adhesive is now applied over the circumferential edge part of the dome portion 22 and over the inner wall of the cylinder 1 in even thickness, as seen in the convex style between the bottom plate 2 and the cylinder 1. Therefore, the adhesive applied areas can transform themselves in correspondence with the transformation of the dome portion 22 and the inner wall of the cylinder 1.
  • the adhesive applied areas can transform themselves accordingly by which the damage by pressure change or impact load is avoided and the satisfactory sealing is kept correct.
  • the increase of the effective areas for the adhesive also promotes the sealing ability when compared with the same produced by the prior art.
  • test container was of the following construction: Diameter : 50mm Height : 124mm Thickness of the cylindrical body at the joint part: 0.27mm Thickness of the bottom part at the joint part: 0.36mm Material : aluminum alloy Adhesive : Epoxy polyamide plastics adhesive 0.6 gram used.
  • test specimen was adapted, as shown in Figure 9, cutting the piece down at 5mm wide at 120 degree intervals, and the specimen was completed in the manner of Figure 10.
  • the stripping power for the present invention shows 14.0 kgs at maximum and 12.7 kgs at minimum, and 13.34 kgs at average, while the same power against the prior art shows 4.5 kgs at maximum and 2.8 kgs at minimum, and 3.66 kgs at average, all of which show that the strength of a container joint of this invention is approximately 3.5 times that of the prior art.
  • the recommendable adhesive is epoxy type, non-solvent, two-part adhesive, and hardening type such as epoxy-amine adhesive, epoxy-polyurethane adhesive and epoxy-polyamide adhesive.
  • the adhesive used in the above field test is epoxy-polyamide type in the following constitutions: MAIN AGENT HARDENING AGENT EPOXIDE EQUIVALENT 165 ⁇ 185 - AMINE NUMBER - 400 ⁇ 440 VISCOSITY 5000 ⁇ 7000 CPS (50 ⁇ 70 N.s.m ⁇ 2) 4000 ⁇ 5000 CPS (40-50 N.s.m ⁇ 2) PERCENTAGE 75% 25%
  • the semilunar-like collective group of adhesive is now prevailing over the inner wall of the cylinder 1 and also over the dome portion 22 of the bottom plate 2, and finally the semilunar-like group is formed into a convex shape by distribution of its adhesive.
  • the applied adhesive is urethane type belonging to the epoxy-amine system. If the pressure increasing step is effected independently, the pressure condition applied can be a few atmospheric pressures for a few seconds. The above condition depends upon the size of the gap between the cylinder 1 and the skirt portion 21 of the bottom plate 2 and also upon the viscosity of the applied adhesive. In a case where the gap is larger and the viscosity is weaker, the pressurising time must be shortened accordingly, while in a case where the gap is smaller and the viscosity is stronger, the time must be increased.
  • the semilunar-like collective group of the adhesive is forced to flow forcibly into the gap between the open end 11 and the skirt portion 21, and the gap is filled with the adhesive as the result.
  • the adhesive stays as it is in the gap.
  • the pressure step is an independent step as above mentioned, but this relative step proceeds simultaneously in correspondence with the curling step.
  • the inside of the cylinder 1 is receiving the fixed pressure, and the adhesive 3 is thus forced to flow into the gap between the cylinder 1 and the skirt portion 21.
  • the bottom plate 2 is pushed into the inside of the cylinder by the curling step.
  • the adhesive 3 is compelled to flow into the said gap even if the pressure time is quite short.
  • the adhesive 3 is also pushed into the gap between the cylinder 1 and the skirt portion 21, whereas the semilunar-like collective group of the adhesive on the upper part of the skirt portion 21 is gradually broken down to move into the gap.
  • the following material is available for the cylinder: steel plate, steel plate furnished with aluminum plating, aluminum sheet, thin cladding steel plate and compound steel plate furnished with plastics coating in its inside.
  • the applicable adhesive epoxy type, two-part adhesive such as epoxy-amine agent, epoxy-urethane agent and so on, with a quality of strong viscosity.
  • the bottom plate 2 After the step of putting adhesive on the inner wall of the cylinder 1, the bottom plate 2 is inserted from the open end 11 of the cylinder 1, and at this instant the adhesive 3 forms the semilunar-like group at the upper part of the skirt portion 21. Then the fixed pressure is put into the inside of the cylinder 1, and the semilunar-like group of the adhesive 3 is forced to flow into the said joint section. In other words, the gap is filled with the adhesive. According to the flow of the adhesive 3 as above, the semilunar-like group is gradually broken down into a formation of convex type, contrary to the semilunar-like form.
  • the adhesive flows over along the inner wall of the cylinder 1 and also over along the inclined surface of the skirt portion 22 into the average thickness, whereas the adhesive supplied areas are easy to transform in accordance with the transformation of the wall or that of the skirt portion 21.
  • the adhesive 3 in those areas stays as it is.
  • the adhesive 3 is dried and hardened to connect tightly the joint section between the cylinder 1 and the bottom plate 2.
  • the adhesive 3 flows forcibly into the gap between the cylinder 1 and the skirt portion 21, and the said gap is filled with the adhesive 3. Accordingly, the adhesive prevailed areas may transform by themselves in correspondence with the transformation of the inner surface of the skirt portion 21 and also with that of the cylinder inner wall, whereas the sealing joint section is neither damaged by an interior pressure change or by an impact load nor the sealing ability is deteriorated.
  • the contacting surface between the inner wall of the cylinder 1 and the skirt portion 21 is larger in comparison with that of the prior art, and therefore the sealing ability is much greater.
  • the assembled body of the cylinder 1 and the bottom plate 2 is upright, whereon heating is temporarily employed upon the adhesive joint section.
  • the applied adhesive is urethane type belonging to the epoxy-amine system, and the heating condition is defined at 150°C for a few seconds.
  • the semilunar-like group of the adhesive 3 at the upper part of the skirt portion 21 gradually runs down into the gap between the open end 11 and the skirt portion 21 because the viscosity is weakened by the heating procedure, and finally the gap is filled with the adhesive 3.
  • the adhesive regains its original viscosity.
  • an infrared heater H is recommended, or else a high-frequency heater is also applicable.
  • the open end 11 is bent inwardly in the curling step.
  • the curling step is the same as for the prior art.
  • the bottom plate 2 is pushed inwardly into the inside of the cylinder 1, and at the final stage of the relative curling step the curling portion is formed to surround the bottom end of the skirt portion 21, wherefore the skirt portion 21 is pinched by the relative curling portions.
  • Adhesive is received in the gap between the tapered upper part of the skirt portion and the inner surface of the cylinder.
  • the applicable adhesive is recommended: two-part adhesive of epoxy type such as epoxy-amine adhesive, epoxy-urethane adhesive with the quality of the strong viscosity.
  • the heating procedure is expressed as an independent step, but this procedure may be included together with the insertion step of the bottom plate 2.
  • this procedure may be included together with the insertion step of the bottom plate 2.
  • the adhesive 3 is furnished, where the bottom plate 2 is inserted from the open end 11 of the cylinder 1 the semilunar-like collective group of the adhesive 3 is formed at the upper part of the skirt portion 21.
  • the applied adhesive is of strong viscosity, enough volume of the adhesive does not exist in the joint section between the cylinder 1 and the skirt portion 21.
  • the semilunar-like collective group of the adhesive 3 flows into the gap of the said joint section and the adhesive 3 fills the said gap.
  • the semilunar-like group of the adhesive 3 gradually decreases its group unity to change into the convex style, and the average prevailing areas of the adhesive 3 adjust themselves to transform in correspondence with the transformation of the cylinder inside wall and with that of the skirt portion 21.
  • the adhesive 3 recovers its original viscosity after the heating is stopped, and thus the adhesive 3 remains filling the said joint section.
  • the bottom plate 2 is tightly fixed at the lower part of the cylinder 1 through the steps of the said curling and caulking.
  • the adhesive 3 stays filling the said gap, whereas the group unity of the semilunar-like collective group of the adhesive 3 gradually decreases to change into the convex style and the average prevailing areas of the adhesive 3 adjust themselves to transform in accordance with the transformation of the cylinder inside wall and with that of the skirt portion 21. It is also understood that the sealing joint section is neither damaged by an internal pressure change or by the impact load nor the sealing ability is deteriorated.
  • the adhesive effecting areas between the inner wall of the cylinder 1 and the skirt portion 21 are larger in comparison with that of the prior art, and therefore the sealing ability is far greater.
  • This embodiment only requires the simple heater apparatus, which does not affect at all the mass production system both costly and systematically.
  • Figures 18 and 19 refer to a still further modification of the invention, which can be applied to any of the embodiments already described.
  • a recess or ditch 27 or a plurality of recesses or ditches 27 at fixed intervals therearound is established, so that the adhesive can flow into the curling portion 28 and it is dried and hardened.
  • the applicable adhesive 3 is two-part and non-solvent epoxy type with 2,500 ⁇ 4,000cp viscosity.
  • the adhesive 3 flows into the curling portion 28 through the ditch 27 and also it fills at the same time the gap between the inner wall of the cylinder 1 and the skirt portion 21. Accordingly, it is not necessary to prepare the slope at the upper part of the skirt portion 21 as shown in Figure 4.
  • the gap tolerance between the cylinder 1 and the skirt portion 21 may be fixed at zero, namely no tolerance is necessary.
  • the adhesive effective areas are increased and the airtightness therewith is also strengthened, wherefore the durability against a shock caused by falling and so on is well maintained.
  • the cut edge is completely covered with the adhesive 3, which prevents the relative edge from becoming rusty, and, further, as the curling portion 28 is filled with adhesive 3 it rejects any incoming of water, and this waterproof situation benefits the step of shrink packaging.
  • the shrink film is likely to deform itself by absorbing the aqueous vapour caused by remaining water therewith.
  • the aerosol container receives the hot water test for leakage after refilling, and during this test it is quite often that the air existing in the gap of the said curling portion 28 comes out to be mistaken as a leakage. This embodiment definitely avoids such a mistake in the relative testing procedure.
