The specific embodiment
Below, with reference to a description of drawings preferred implementation of the present invention.The metal sealable tank once more of present embodiment (removing the jar body of lid) 1, as Fig. 1 and shown in Figure 2, constitute: parts bottom 3 crimpings of split are installed in the lower end that engages tank body 2.That is, above columnar body 4, form container finish 5, and bottom 3 is installed at the open end place crimping of the lower end of tank body 2.On this container finish 5, the metal Kaifeng supervision type lid 7 with resinous liner 6 utilizes known in the past capping apparatus and roll forming, forms thread groove 9 on the cylindrical portions may in the skirt section 8 of lid 7 and should cover 7 and be installed on this container finish 5.
In addition, as shown in Figure 3, on the outer peripheral face of container finish 5, be formed with ridge 10, and then thereunder, be formed with flanging muscle (PVC-De) portion (be groove, be raised line) 11 of annular with respect to outside face with respect to inside face.The flanging muscle portion 11 that this is annular, when utilizing known in the past capping apparatus to be installed in metallic lid 7 on the container finish 5, the forming rolls of capping apparatus (not shown) enters and pushes and make and cover 7 lower end wall (the Kaifeng supervision that is formed on the lower end of covering 7 skirt section 8 with 12 end portion) and be shaped to the epimere portion of flanging muscle portion 11, cover 7 card is only under the monitor state of Kaifeng thereby make with respect to container finish 5.
The lid 7 of present embodiment, comprise metal shell 13 and resinous sealing liner 6, shell 13 is that liner 6 is set on the inner surface side (lower face side) of this top plate portion 14 with being general cylindrical shape from the structure in the skirt section 8 of hanging down on every side of top plate portion 14.The bottom in the skirt section 8 of the lid 7 (being shell 13) under the state before being installed on the container finish 5 that engages tank body 2 by roll forming, i.e. lower hem place below more leaning on than the predetermined cylindrical portions may of shaping thread groove being formed with the Kaifeng supervision in the following manner with 12: promptly can cut off the bridge 12B that is formed between the horizontal narrow slit 12A and 12 separation are with in the supervision that will break a seal.
The material of lid 7 (perhaps shell 13) limits especially, for example can use the metallic material that is coated with the aluminium alloy plate that makes the epoxy phenolics that the olefine kind resin powder disperses etc. on inner surface side.In addition, the raw material of liner 6 can use for example low-density polyethylene and the elastomeric composite material of ethylene-propylene copolymer, polypropylene and known resin materials such as the elastomeric composite material of phenylethylene, polyester elastomer.And liner 6 can be by following known compression molding method etc. and is shaped: promptly extrude above-mentioned resin material and carry out mold pressing with molten condition in the inner surface side of top plate portion 14.
On the other hand, the tank body of present embodiment, on the neck of the open end undergauge that makes columnar joint tank body 2, be formed with ridge (external screw thread) 10 and flanging muscle portion 11, but from applicant's various experiments as can be known, existence significantly influences to turning on property in the direction of the ladder difference portion 15 of the side of tank body 2.
At this, tank body 2 and the ladder difference portion 15 of engaging is described.Engage tank body 2 and constitute, above-mentioned metal sheet is cut to a jar amount size and it is configured as cylindrical shape, and the both ends of this metal sheet are overlapping slightly and weld.Represent the junction surface 16 of formation like this as amplification view among Fig. 4, because this junction surface 16 is than other part wall thickness, so produce ladder difference portion 15.And this ladder difference portion 15 is on the outside face side and inner surface side that engage tank body 2, the direction difference of projection is in example shown in Figure 4, outside on the face side, the ladder of projection is poor laterally for the part in the left side of Fig. 4, inner surface side in contrast, the ladder of projection is poor to the inside for the right side.
Promptly, cover on container finish 5 and when carrying out roll forming will covering 7, push to the ridge 10 of the neck of container finish by the shell 13 that the screw forming roller will cover on container finish 5, so, deep hole pinching engages tank body 2 and the ladder difference portion 15 at the junction surface of the neck that forms is transferred to and covers on 7, its result forms the ladder difference trace 17 based on the ladder difference portion 15 that engages tank body 2 on the thread groove 9 of lid 7.And being formed on the ladder difference trace 17 that covers on 7 the thread groove 9 becomes the state that the ladder difference portion 15 with the junction surface 16 of tank body 2 sides faces, and is installed on the container finish 5 thereby will cover 7.More specifically, the dip plane of the ladder difference portion 15 of the dip plane of the ladder difference trace 17 of the inner surface side of lid 7 and the outside face side at junction surface 16 is mutual opposed state, perhaps, the ladder difference trace 17 of the inner surface side of lid 7 thread groove 9 and container finish 5 or with the ladder difference portion 15 of the outside face side of neck be the ingear state.
To making these ladders differ from 17 and ladder difference portion 15 is more positive or the direction swivelling covers 7 of more effectively engaging and opening under the situation of lid, the ladder difference portion 15 that lid 7 ladder difference trace 17 must be crossed the neck at junction surface 16 can turn on, therefore make as can be known cover 7 begin to rotate turn on the moment of torsion increase.
In addition, cover at 7 o'clock opening, when the ladder difference trace 17 of lid 7 inner surface side is crossed the ladder difference portion 15 at junction surface 16, sometimes the tunicle that has the rib portion of ladder difference portion 15 peels off, 7 coating on inner surface is pruned and coating slag (being also referred to as the resin slag) sticks to the situation on the container finish 5 owing to rib portion causes covering, the leak tightness variation, the coating slag that become when sealing are once more sneaked into the reason to content, and cause unhygienic.
As its countermeasure, the joint tank body 2 of present embodiment constitutes, even if will cover 7 at the ladder difference trace 17 of lid 7 thread groove 9 under for the state relative with the ladder difference portion 15 at the junction surface 16 of the neck of tank body 2 is installed on the container finish 5, when turning on, turn on direction and also be ladder to lid 7 and differ from the 17 direction swivelling covers 7 that separate with the ladder difference portion 15 at junction surface 16 and turn on.Promptly, the ridge 10 that is formed on the neck forms following direction, and promptly the upside of 16 (overlapping portions) (outside of the radial direction of the outside face side of jar body 1 or jar body 1) is turned on towards downside (inboard of the radial direction of the inner surface side of jar body 1 or jar body 1) lid 7 from the junction surface.Therefore, cover at 7 o'clock opening, can swivelling cover 7 and in the thread groove 9 (negative thread) of lid 7 inside face of ladder difference trace 17 can not be stuck in the ladder difference portion 15 at junction surface 16.
In addition, turn in case will cover 7, then supervision band in the Kaifeng of lid cuts off and the lower hem broadening of lid, and in the time of need sealing, the clearance C between the gap between ridge 10 and the thread groove 9, above-mentioned ladder difference portion 15 and the ladder difference trace 17 is as shown in Figure 5 than big before turning on again.Therefore, the former ladder difference portion 15 and the problem of ladder difference trace 17, (when sealing once more) no longer become problem when sealing again.
On the other hand, on the flanging part 18 that is formed on the end that engages tank body 2, volume ground crimping forms under the situation of flanging part 18 outside, owing to junction surface 16 is turned over, so that the direction of the ladder difference portion 15 at the end face place of flanging part 18 shows as is opposite with the direction of the ladder difference portion 15 of neck at flanging part 18 end faces.Therefore, need be than the ladder residual quantity of the ladder difference portion 15 that on ridge 10, forms little and ladder difference end face when turning on portion 15 do not influence cover 7 begin rotate, preferably from engage the ladder residual quantity when beginning to reduce to engage tank body 2 for the stage of cylinder as far as possible, preferred weld is below the 0.07mm.In addition, the oral area 5 of tank body 2 that preferably makes in this wise welding is with respect to the diameter undergauge of tank body 2 more than 15%, by from the compressive force of circumferencial direction the ladder residual quantity of the ladder difference portion 15 of neck being reduced.
Make container finish 5 with respect to the necking down rate of tank diameter than 15% littler big necking down forming process in, the limit of the plastic working at junction surface 16 is low, can not expect to reduce the ladder residual quantity at junction surface 16.
Shown in Fig. 6 (A), as the wide-mouth lid used of sealable tank once more, except top plate portion being formed the shape of general plane shape, the lid that the panel of top plate portion 14 is caved in significantly, when such lid is installed in container finish, can tell on to the necking down rate of said vesse oral area.
Promptly, turn back and pre-crimping at the open end that makes container finish 5, and conquassation from the side and when forming flanging part 18, because it is vertically elongated that flanging part 18 forms, so the flanging part 18 and the contact load between the liner 6 that produce owing to the clamp load of pressing cover top plate portion 14 are littler than cross section circle (perhaps odd-shaped cross section) crimping, the tendency that has leak tightness to descend.Therefore, in order to compensate contact load, when roll forming, shown in Fig. 6 (B), under the state of the top plate portion 14 of pressing cover shell 13, use reshapes instrument (not shown) and the bight part 14a that covers 7 panel is out of shape laterally, and makes and cover 7 bight part 7a and be out of shape to the inside, clamps flanging part 18 to increase the power of connecting airtight of liner 6 via liner 6 from both sides.Even if in this case, if carry out the necking down processing of container finish 5, the ladder residual quantity at junction surface on the surface of the flanging part 18 that joins with liner 6 is become below the 0.05mm with above-mentioned necking down rate, can reduce turning on Effect on Performance.
Engaging tank body 2 mainly contains bonding and welds this dual mode, particularly under the situation of the welded tank that uses welding manner, as shown in Figure 7, be formed on the coating 19 on the steel plate, reserve the width about 1.5mm to 3mm and form the zone of the joint reservations at the two ends that will engage when make engaging tank body 2.Carry out because be welded under the no painting state, so, must repair lining this zone in order to ensure the corrosion stability after the welding.With at the junction surface 16 states that are formed with bigger ladder difference portion 15 make columnar body 4.Like this, make the joint tank body 2 of the columnar body 4 and the coating 19 that on the inner peripheral surface except junction surface 16 of this body 4, is covered.
The junction surface 16 that the nothing of using inside face repairing resin to cover the inner surface side of this joint tank body 2 is repaired state.In Fig. 7, the inside face of the circumferencial direction of body 4 is repaired the width setup of coating 20 in the scope of 7mm to 15mm, so that lining property and operation are good.This inside face is repaired coating 20 and can be formed by individual layer or composite bed, repairs the method for coating 20 as forming inside face, the method for coating inside face coating is arranged and paste the method for paying banded resin film.
Coating when repairing application can use the curing type synthetic resin of polyesters or phenolic etc., particularly uses thermohardening type synthetic resin.But these thermohardening type synthetic resin are after coated and dried, and hardness increases, and are shaped at the neck of open end, crimping is shaped and during the conquassation shaping of folding and conquassation flanging part etc., be easy to generate phenomenons such as coating crack and film separation, so can not thickly be coated with.Therefore, if consider that it is to paste the method for paying banded resin film that corrosion stability is then wished.
With the cooresponding situation that is shaped by repair paint under, can consider to approach repairing, but if inside face is repaired the thin thickness of coating 20, then owing to the reason of flowing power etc., be difficult to repair fully the ladder difference portion 15 of welding, to turn on performance and carrying out under the harsh situation of harsh neck is shaped, crimping is shaped back processing in order to improve, the coating eyelet may appear and the phenomenon of corrosion stability deficiency, at this situation, by paste paying a certain thickness banded resin film, the harmful effect to corrosion stability etc. can be suppressed for less.Particularly when crimping shaping neck opening end, viewpoint based on the flatness of guaranteeing leak tightness and flanging part end face, be involved in and after crimping is shaped in circle, carry out the harshness shaping that conquassation is shaped even push this flanging part from the side to stacked state, film can not damage yet, peel off, and can keep corrosion stability.
When paste paying a banded resin film and repair, the temperature that the banded resin film of the inside face of body 4 is pasted the zone of paying press-fits banded resin film to this zone after being heated to 170 ℃ to 230 ℃ scope.As pasting the method for paying banded resin film, can make banded resin film from film as heat adhesiveness, the tack coat of thermosetting resin also can be set on banded resin film.As banded resin film, transparent thermoplastic macromolecule resin's monomer in the copolyester resinoid that can use the polyester resin of for example pet resin, polybutylene terephthalate resin etc., constitute by copolymerization of polyethylene terephthalate and isophthalic acid ester acid etc., acrylic resin, polycarbonate resin, polystyrene resin, polyolefin resin, Koroseal etc., the perhaps banded resin film that constitutes by the complex of above-mentioned resin.In order to make lining property and operation and back processability good, preferably will paste pair thickness setting at the banded resin film on the inner surface side of body 4 in the scope of 15 μ m to 45 μ m.
Banded resin film do not have extensions, extend all can and preferably form by composite bed, in this case, banded resin film has in the face of the 1st layer of body 4 sides and the 2nd layer of private side of facing body 4 with the 1st ply.In addition, the 1st layer preferably is made of the thermoplastic base resin in 175 ℃ to 230 ℃ scopes of fusing point, and the 2nd layer, fusing point constitutes in 200 ℃ to 255 ℃ scopes and by biaxially oriented thermoplastic base resin.
And the 2nd layer the fusing point of thermoplastic base resin is higher 15 ℃ to 80 ℃ than the fusing point of thermoplastic base resin that constitutes the 1st layer, more preferably high 20 ℃ to 40 ℃ mode is selected the material of layers 1 and 2 to constitute.In addition, the 1st layer thickness setting is 70% of the gross thickness that surpasses banded resin film.After should the band shape resin film being fitted on the junction surface 16, to be higher than the 1st layer fusing point, the temperature that is lower than the 2nd layer fusing point be carried out the back heating.As thermoplastic base resin as used herein, can use for example poly-vinyl resin, sex change poly-vinyl resin, acrylic resin, sex change acrylic resin, polyolefin resin, but when using the such polyester resin of pet resins as inside face coating 19, based on the resin viewpoint of connecting airtight property each other, preferably use polyester resin as the 1st layer.And, consider corrosion stability and operation and back processability, the thickness that inside face is repaired coating 20 preferably sets at 15 μ m to 45 mu m ranges, more preferably is set in 18 μ m to 30 mu m ranges.
In addition, by being more than 70% of gross thickness of banded resin film with the 1st layer thickness setting, the bight of the ladder difference portion 15 on the inner surface side at the junction surface 16 that can be covered fully can prevent to get rusty reliably.In addition, preferably repair the junction surface 16 of film lining inner surface side with the above band shape of thickness 15 μ m.Thus, can further reduce the ladder residual quantity of flanging part surface, under state with the ladder difference portion 15 at the lip-deep junction surface 16 of banded resin film coating flanging part, the ladder residual quantity can be suppressed at below the 0.05mm, preferably below 0.04mm, when Jiang Gai turns on, can reduce and liner 6 between seize resistance.
If the banded resin film thickness of the inner surface side at lining junction surface 16 is thinner than 15 μ m, then when the carrying of pasting to tank body 2 inside faces in the process of paying junction surface 16, be difficult to loading and unloading.If opposite thickness is thicker than 45 μ m, the loading and unloading problem when then not having carrying, but be not easy to cut off film, so and because the above thickness of necessary thickness that is covered is also uneconomical.
The raw material of the tank body 2 of present embodiment uses the tank body material of employed 3 complete jar of usefulness usually, for example, have 2 layers of tunicle of crome metal and hydrated chromium oxide sheet iron of wuxi, implement taggers tin class steel plate zinc-plated and that the chromate finish coat is handled, nickel plating and implementing implements tin glazed steel plate as thin as a wafer that flash plating tin and chromate finish coat handle after the DIFFUSION TREATMENT, implement the metal sheet of nickel-clad steel plate that nickel plating and chromate finish coat handle etc.Usually use face (constituting the face of tank inner surface) to go up to form coating (this becomes following inside face coating 19) and thickness of slab is the steel plate of 0.10～0.25mm in a side of this steel plate.
