Detailed description of the invention
In order to the mode carried out an invention
Below, with reference to accompanying drawing, embodiments of the present invention are described.Fig. 1 is the cutaway view of the lid made of resin 1 of the 1st embodiment of the present invention, and Fig. 2 is the figure watching this lid made of resin 1 from dorsal part.This lid made of resin 1 is the lid that the container finish being installed in the not shown container that plastic bottle etc. is defined by synthetic resin uses.Lid made of resin 1 is the lid be shaped integratedly by polyethylene by compression molding or injection moulding, the tear-strap (tamper evident band) 4 that the lower ora terminalis 3a possessing the sidewall portion 3 being positioned at the periphery of container finish that superposed top board 2, from then on the outer peripheral edges 2a of top board 2 extend downward and sidewall portion 3 has therewith linked.In addition, the raw MAT'L forming lid made of resin 1 without particular limitation of, except the polyethylene employed in the present embodiment, be also applicable to using polypropylene etc.
Lid main body 5 is constituted by above-mentioned top board 2 and sidewall portion 3.Top board 2 is formed to have the discoid of required size, on the back side 2b of this top board 2, the inner ring 6 extended inward, the ring-type teat 7 given prominence to inward at the radial outside of this inner ring 6 and further at the outer shroud 8 that the radial outside of this ring-type teat 7 extends inward with the size shorter than inner ring 6 are integrally formed.If lid made of resin 1 is installed in container finish, then the inner peripheral surface close contact of inner ring 6 and this container finish, meanwhile, the outer peripheral face close contact of outer shroud 8 and this container finish.Circular protrusion 7 abuts with the open end of container finish and is out of shape.
Due to the existence of above inner ring 6, outer shroud 8 and ring-type teat 7, the leakproofness of container finish is maintained high.In lid made of resin 1, because have employed with can not arranging packing seal by unibody construction airtight for container finish, so compared with the lid made of resin constructed with the binary possessing packing seal, Fabrication procedure is simplified.In the lid of binary structure being provided with packing seal, because there is gap between top board and packing seal, so, there is the problem being difficult to clean lid made of resin.About this point, in the lid made of resin 1 of present embodiment, because all integral, the above-mentioned gap being present in binary structure does not exist.Therefore, cleaning liquid at short notice throughout the corner of inner side to lid made of resin 1, so, easily clean, can be corresponding with aseptic filling.
Sidewall portion 3 is the sidewall portions being formed as the cylindrical shape with required size, within it on side face 3a, defines the internal thread part 9 be threadedly engaged with container finish.In addition, internal thread part 9 by circumferentially spaced predetermined distance in sequential like multiple protruding part 9A of being provided with form, fraction can be passed through towards above-below direction.On the outer peripheral face 3c in sidewall portion 3, define the annular knurl groove 10 extended towards above-below direction.
Boundary line sections in sidewall portion 3 with tear-strap 4, defines multiple bridging part 11 with circumferentially separating predetermined distance.Multiple bridging part 11, by interconnected to lid main body 5 and tear-strap 4, if stretched by the power specified, ruptures.Tear-strap 4 is formed as going some cylindrical shape of enlarged-diameter along with toward below.In the inner side of tear-strap 4, be provided with engaging portion 12.Engaging portion 12, inwards turns back oblique upper from the bottom 4a of tear-strap 4, and is circumferentially formed in interrupted shape ground.Engaging portion 12 can inward, foreign side and below carry out elastic deformation.And this engaging portion 12, is positioned at the roughly downside in the not shown beading portion (bead portion) of container finish at lid made of resin 1 under being installed in the state on container finish, locking with this beading portion by operation of uncapping.
If the lid made of resin 1 being arranged on container finish starts to be rotated in direction of uncapping, then engaging portion 12 is locking with beading portion, acts on tensile force to bridging part 11, if lid made of resin 1 is rotated further, then bridging part 11 is stretched greatly, is tapered down, until fracture.Thus, the lid main body 5 be made up of top board 2 and sidewall portion 3 is separated by from tear-strap 4, and container is uncapped.
As shown in Figure 2, the radially inner side of the inner ring 6 in the back side 2b of top board 2, has formed rib 13 outstanding inward.On rib 13, define plane end face 14 and the 2b continuous print dip plane, the back side 15 at the both sides of this end face 14 and top board 2.This rib 13, is made up of the annulus 16 centered by the mid point 2c of top board 2 and 6 epitaxy parts 17 linearly extending from annulus 16 towards radial outside.Annulus 16, is formed roughly cellular as a whole, and the size t1 on 1 limit is 4.5mm.The width t2 of annulus 16 and each epitaxy part 17 is 1.5mm.Each epitaxy part 17, extends from 6 external angle 16a of annulus 16 towards radial outside, and the length t3 of this each epitaxy part 17 is 3.0mm.The outer end 17a of these 6 epitaxy parts 17 is formed arc-shaped, and each outer end 17a and inner ring 6 are left mutually.The outer end 17a of each epitaxy part 17 and distance t4 that leaves of inner ring 6 is 1.0mm.This leaves distance t4 and is preferably 0.5 ~ 1.5mm.This is because, if it is less than 0.5mm to leave distance t4, then when top board 2, inner ring 6 etc. have been out of shape, there is outer end 17a and the interactional danger of inner ring 6 of each epitaxy part 17, if it is larger than 1.5mm to leave distance t4, then the length t3 of each epitaxy part 17 diminishes corresponding amount, becomes and is difficult to obtain the effect produced because of the existence of this each epitaxy part 17.In addition, the above-mentioned size of annulus 16 and each epitaxy part 17, width, length are an example, are not defined.
The height h1 of the rib 13 be made up of annulus 16 and 6 epitaxy parts 17 is that 0.3mm(is with reference to Fig. 1).The thickness d 1 of top board 2 is 0.5mm, by this top board 2 is made thin-walled, achieves lightweight.Here, the formula below the height h1 of rib 13 and thickness d 1 demand fulfillment of top board 2.
The thickness of the end face 14 of thickness d 1(from the surperficial 2d of top board 2 to rib 13 of the height h1+ top board 2 of rib 13) > 0.7mm
Fig. 3 is on the top board 2 being embedded in the lid made of resin 1 in axle (printing fixture) 50, by printing rubber blanket 51 implement print time analyse and observe instruction diagram.Lid made of resin 1 is embedded in axle 50, and the top board 2 of this lid made of resin 1 is by from back side 2b side bearing.In this case, the printing rubber blanket 51 that attached to ink is pushed to the surperficial 2d of top board 2, to the printed patterns of this surperficial 2d printing regulation.
Because be provided with rib 13 on the back side 2b of top board 2, so when lid made of resin 1 is embedded in axle 50, the areal of support 50a of this axle 50 abuts with the end face 14 of rib 13.Therefore, axle 50 does not directly contact with the back side 2b of top board 2.Annulus 16 little Yi Quan compared with the areal of support 50a of axle 50 of rib 13, the entirety of this annulus 16 abuts with this areal of support 50a.
In order to prevent applying excessive thrust pressure by printing rubber blanket 51 to top board 2, preset when this printing rubber blanket 51 is closest to the interval D of the material of two during axle 50 51,50.In the present embodiment, because the thickness of the end face 14 from the surperficial 2d of top board 2 to rib 13 becomes more than 0.7mm, so, can printing rubber blanket 51 and the setting of the interval D of axle 50 be expanded to 0.7mm more than.By setting the interval D expanded, when there occurs the not embedding state that lid made of resin 1 is not embedded in axle 50, the printing rubber blanket 51 that attached to ink can be made not contact with axle 50.
According to the lid made of resin 1 of above-mentioned present embodiment, because quilt is as not using the monomer lid of packing seal to form, so, Fabrication procedure is simplified, meanwhile, when implementing printing to the surperficial 2d of top board 2, because the rib 13 making axle 50 directly not contact with the back side 2b of this top board 2 is given prominence to inward from this back side 2b, so set wide by the interval of printing rubber blanket 51 and axle 50 with can not changing the thickness of top board 2, the ink of printing rubber blanket 51 can not be attached in axle 50.Thus, easily manufacture, and do not cause the increase of weight, the ink in printing process can be prevented to the attachment of the back side 2b of top board 2.In addition, even if when the ink of printing rubber blanket 51 is attached in axle 50, because this axle 50 does not directly contact with the back side 2b of top board 2 because of the existence of rib 13, so, also can prevent from being made dirty this back side 2b by ink.
The overall annulus 16 abutted with the areal of support 50a of axle 50 is made, so by this axle 50 not top support plate 2 partially, the distortion of this top board 2 during printing is suppressed owing to being provided with.Thereby, it is possible to implement printing usually even and attractive in appearance to the surperficial 2d of top board 2, reduce the generation of bad product.In addition, the top board 2 of thin-walled can be strengthened by the annulus 16 and epitaxy part 17 that form rib 13, the distortion of the lid made of resin 1 preventing the flexure etc. because of this top board 2 from causing.
And then, by being provided with 6 epitaxy parts 17 extended from annulus 16 towards radial outside, even if become the state that axle 50 offset by relative to top board 2, also this top board 2 partially can not be supported.Therefore, the distortion of the top board 2 during printing is suppressed, can implement printing usually even and attractive in appearance, reduce the generation of bad product to the surperficial 2d of this top board 2.
Because the outer end 17a of each epitaxy part 17 and inner ring 6 are left mutually, so, rib 13 and inner ring 6 can be made not to influence each other.If the outer end of each epitaxy part is connected with inner ring, then when top board, sidewall portion are out of shape because of certain reason and concomitantly rib has been out of shape therewith, because of the impact of this rib of being out of shape, the decline of the roundness of coupled inner ring becomes remarkable, and the leak tightness to container finish produced by lid made of resin declines.In the lid made of resin 1 of present embodiment, because rib 13 and inner ring 6 do not influence each other, so, even if top board 2, sidewall portion 3 are out of shape because of certain reason, accompany therewith, rib 13 is out of shape, and the impact of the distortion of rib 13 is not delivered to inner ring 6 yet, and the decline of the roundness of this inner ring 6 is suppressed to Min..Thereby, it is possible to improve the leak tightness to container finish produced by lid made of resin 1.On the other hand, because the impact of the distortion of inner ring 6 is not delivered to rib 13 yet, so, the distortion of the top board 2 caused by the impact of the distortion of inner ring 6 when lid made of resin 1 can be prevented to be installed in container finish etc.
