The specific embodiment
Fig. 1 is the block diagram of the container for packing of relevant one embodiment of the present invention.Fig. 2 is that the part of the A part of Fig. 1 enlarges block diagram, birds-eye view and lateral plan.
In this embodiment, as container for packing, take out container body 1 and describe.Container body 1 has base plate 20 and all side frames (cycle side plate) 10 of holding up to oblique foreign side around the base plate 20.Base plate 20 be for example four jiaos be circular roughly oblongs.Thus, container body 1 main body is shaped as rectangular dark ware shape.And the opening of container body 1 is divided by the upper end of all side frames 10.Form outwardly directed bead (flange) 11 in the upper end of all side frames 10.Bead 11 promptly becomes the bead around the round of vessel port around the upper end of all side frames 10.Bead 11 plays a part to make vessel port to remain on the intensity of inward-outward direction.
The outer peripheral edges 11a minor fluctuations of bead 11.In illustrated embodiment, bead outer peripheral edges 11a is seen as the waveform shape of fine fluctuation from the top.In this case, the difference d of the crest of bellows-shaped (waveform shape) and trough is less than 0.5mm.In addition, spacing (pitch) (interval of the interval of crest and crest or trough and the trough) p of bellows-shaped (waveform shape) is about 1mm.
But the difference d of this trough can be in the scope of 0.2～1mm, preferably less than 0.5mm.In addition, spacing p can be in the scope of 0.5～5.0mm, about preferred 1.0mm.
By bellows-shaped being limited in the above-mentioned number range, can preventing to injure finger and cut off packing film by bead outer peripheral edges 11a.
Part block diagram, birds-eye view and the front elevation of other shape of Fig. 3 bead 11 that to be expression stretch out to foreign side from the upper end of all side frames 10 of container body 1.In the embodiment shown in Fig. 3, bead 11 integral body are along edge of opening minor fluctuations up and down.Thus, though bead outer peripheral edges 11a almost completely is straight when overlooking, if (if from horizontal direction) from the side, the shape of minor fluctuations about the periphery 11a of (along continuous straight runs extensions) of extending along transverse direction becomes.The crest of this fluctuation and the difference d of trough and last embodiment coexist in the scope of 0.2～1.0mm mutually, and Bo Dong spacing (interval of the interval of crest and crest or trough and trough) p is in the scope of 0.5～5.0mm in addition.
The direction of the ripple of bead outer peripheral edges 11a also be can be used as the ripple of overlooking the horizontal direction of seeing fluctuation as a last embodiment, also can be used as the shape that as present embodiment, fluctuates along the vertical direction in addition from transverse direction (horizontal direction).
Perhaps, will go up an embodiment and present embodiment and combine, two sides that the ripple of bead outer peripheral edges 11a also can be at transverse direction (horizontal direction) and longitudinal direction (vertical direction) go up the compound bellows-shaped of fluctuation.
To any one situation, by making the fine fluctuation of bead outer peripheral edges 11a, periphery 11a can not have the edge shape of the linearity that thin resin making sheet has been sheared, but has the edge shape of fine fluctuation as playing wave, so the inoffensive finger in edge of this fine fluctuation, the contact packing film can not cut off packing film yet.
Fig. 4 be expression relevant of the present invention other the bead 11 of embodiment and the part enlarged drawing of the formation of outer peripheral edges 11a.
Shown in Fig. 4 (A), to the tiny convex-concave of bead 11 whole formation.That is, be formed on the outstanding a plurality of kicks 12 that form of upper face side of bead 11 and regularly at a plurality of small ruts 13 of the recessed formation of reverse side of bead 11.And by shearing described bead 11, its outer peripheral edges 11a will becoming shown in Fig. 4 (B), has the edge of fluctuation along the vertical direction that is formed by the shear line that is breaking at a plurality of kicks 12 of forming on the bead 11 and a plurality of small rut 13.
Under the situation of present embodiment, bead outer peripheral edges 11a neither linearity, but the fluctuation shape, the sharpness when therefore having reduced the contact of finger or packing film.
Illustrated that in the above embodiment the opening periphery that makes container body 1 is the container of bellows-shaped.But the present invention is not only to container body 1, and the opening periphery that covers the lid on this container body 1 is suitable for.Promptly adopt the container for packing of plastic sheet moulding, store the container for packing of food etc. especially, not only will be manufactured with container body, and will be manufactured with the lid that is positioned on this container body.And lid is also identical with container body, and edge of opening is sheared and formed thin plate.Also adopt bellows-shaped at this by edge of opening, can make the contact surface of opening periphery become soft contact surface from sharp contact surface to lid.
Fig. 5 is the diagram figure that overlooks of container body 1 or lid 18, and bead 11 is represented by cross hatch.Can implement any of above-mentioned bellows-shaped to the periphery 11a of this bead 11.In addition, if outstanding being arranged on is positioned on the handle 15 that can pinch operation when the lid of maybe this having been set up on the container body is opened with lid from bead 11, then the outer peripheral edges of preferred this handle 15 are also paid bellows-shaped.
In addition, as shown in Figure 6, with container body 1 and lid 18 by connecting portion 16 with collapsible mode bonded assembly situation under, can on the outer peripheral edges of the bead 11 of the outer peripheral edges of bead 11 except the external margin of this connecting portion 16, container body 1 and lid 18, pay bellows-shaped.
In addition, if operation is outstanding with handle 15, so preferably on the outer peripheral edges of this handle 15, also form bellows-shaped.
In the explanation of reference Fig. 5 and Fig. 6, though represented on nearly all zone of the outer peripheral edges of the bead 11 of the outer peripheral edges of the bead 11 of container body 1 and lid 18, to apply the example of bellows-shaped, can be not yet at the All Ranges of the outer peripheral edges of bead 11 and only pay bellows-shaped in any range in outer peripheral edges.
In the above description, though will in the peristome of container body or lid, exist the situation of the bead of stretching out laterally to be illustrated as an example, even but in the opening periphery of container body or lid, do not exist under the situation of bead, also can form bellows-shaped to the opening periphery.
The diagram figure of the skiagraph of the container body of 3 kinds of expression in Fig. 7.Also can pay bellows-shaped on its outer peripheral edges under the situation as described below respectively: possess as Fig. 7 (A) around openings that is shown under the situation of bead 11 on its outer peripheral edges (on the T1 part among Fig. 7 (A)), in Fig. 7 (B) under the situation of container shapes of expression on the outer peripheral edges of representing by T2, under the situation of Fig. 7 (C) on the outer peripheral edges of representing by T3.
In addition, Fig. 8 is the graphic skiagraph of the shape example of expression lid.Also can be on the outer peripheral edges T4 part in the bead of lid under the situation of Fig. 8 (A), and under the situation of Fig. 8 (B) towards below edge of opening T5 on, pay bellows-shaped.
Then, with reference to Fig. 9,10, the manufacture method with reference to the container body 1 of Fig. 3 explanation is described.
Container body 1 will be supplied to by the cylinder thin plate that the synthetic resin material forms on the metal mould for formation P1, after making thin plate according to the metal paattern warpage, be transported to die-cut mould, and use and for example the container that has been shaped to be sheared and separate from the cylinder thin plate by the shears that possesses Thomson (Thomson) blade.
The example of expression metal mould for formation P1 among Fig. 9.Metal mould for formation P1 forms along the vertical direction bellows-shaped W with fine waveform fluctuation to the be shaped part of bead 11 of major general.By adopting this metal paattern P1 to be shaped, can make the waveform of the bead 11 formation above-below directions of container body 1.
Figure 10 represents that with sheet moulding be with the example of the shearing of die-cut mould P2 after the container shapes.This shears the example that Thomson blade C is adopted in the example expression.The blade of Thomson blade forms waveform shape on the direction vertical with paper.By using this Thomson blade C, can make the periphery of bead not only form bellows-shaped at above-below direction also left and right directions.
In addition, as the embodiment as shown in Fig. 3 and Fig. 4, if bead is formed the bellows-shaped of above-below direction, even adopting the blade of the shearing knife edge of Thomson blade C etc. so is the blade of linearity, is also to be the shape that fluctuates along the vertical direction though the bead outer peripheral edges after the shearing are linearity when overlooking when seeing from transverse direction (horizontal direction).Therefore,, can use the shearing knife edge of straight line, and then make simple with making change by on bead, paying the ripple of above-below direction in advance.
Also have, under the situation that the edge of opening of container for packing is sheared, the temperature of gas atmosphere can be in 15 ℃～55 ℃ scope.Under the temperature of moulding product was situation below 15 ℃, the moulding product were easy to generate and break and become defective products, if the temperature of moulding product becomes high temperature more than 55 ℃ conversely, there is the danger that produces deliquescing and be out of shape in the moulding product so.
