The short brink innovation 1b of portion of bottom 1 is just highly low than the long side innovation 1a of portion, its structure is practically identical, the inboard vertical component effect 1b1 that is vertically extended upward substantially by the edge of 1 the base plate 1c from the bottom, the outward extending horizontal part 1b2 of on even keel and be in substantially parallel relationship to the 1b3 of outside vertical portion that extends on inboard vertical component effect ground downwards from the edge part of horizontal part 1b2 and constitute substantially from the upper end of inboard vertical component effect 1b1.On the short brink innovation 1b of portion, also form above-mentioned cloudy articulated section H1.In addition, on the back side of the lower edge 3a of short sidewall 3, the also corresponding cloudy hinged H1 that sets in the short sidewall innovation portion of bottom 1 forms above-mentioned positive articulated section H2.And, be articulated and connected at cloudy articulated section H1 that sets on the short brink innovation 1b of portion of bottom 1 and the positive articulated section H2 that on short sidewall 3, sets.

The incision recess h2 of the cloudy articulated section H1 that 1 the short brink innovation 1b of portion upward forms bottom being formed in extends near the base plate 1c or base plate 1c of bottom 1.The base plate 1c that promptly cuts the lower end h2a of recess h2 and bottom 1 is on same plane or be positioned near the base plate 1c.Owing to constitute like this, as shown in Figure 2, when the short sidewall 3 that the elder generation in the relative short sidewall 3 was fallen when direction was fallen at the end 1, the supporting pieces h10 of the positive articulated section H2 that sets on the short sidewall 3 not can be formed in the short brink innovation 1b of portion on the lower end h2a of incision recess h2 of the cloudy articulated section H1 that forms contact.As illustrated in fig. 11, lack the cardinal principle of plate-like portion 3b of sidewall 3 all in fact with 1 base plate 1c contacts in the bottom.In addition, at present embodiment, as illustrated in fig. 10, the lower end h2a of expression incision recess h2 and the base plate 1c of bottom 1 are on same plane.

In addition, on the inner face upper end of the inboard vertical component effect 1a1 of the both sides that are located at the incision recess h2 that forms on the inboard vertical component effect 1b1 of the short brink innovation 1b of portion, hook h3 is set; Be positioned at the height of the following incision recess h2 of the h3b of eaves portion of this hook h3, promptly the height W10 from the h3b of eaves portion of hook h3 to the lower end h2a that cuts recess h2 has the height more than the twice of width of cloth W7 of the supporting pieces h10 that constitutes positive articulated section H2.

The state that is folded from Collapsible container, the short sidewall 3 of level substantially substantially during vertical stand-ups, as shown in Figure 3, bottom the lower edge 3a of short sidewall 3 is placed on the horizontal part 1b2 of 1 the short brink innovation 1b of portion.Meanwhile, the h3b of eaves portion that touches the hook h3 of piece h12b from the inboard vertical component effect 1b1 that is arranged on the short brink innovation 1b of portion that forms in bottom 1 of hinged block h12 leaves the distance D 2 of regulation, is positioned at the below of the h3b of eaves portion.Thereby as shown in figure 13, by the state of vertical stand-ups substantially, when mentioning short sidewall 3, bottom 1 is motionless at shortwall 3, just shortwall 3 from the bottom 1 distance D 2 of the eaves h3b that touches piece h12b and hook h3 that moves up above-mentioned hinged block h12.

Fold the assembling boxlike-forming collapsible container, at first, a short sidewall 3 in the vertical substantially relative short sidewall 3 was fallen to bottom 1 direction.In bottom 1 direction was rotated, the lower edge 3a that is placed on a short sidewall 3 on the horizontal part 1b2 of the short brink innovation 1b of portion threw off from horizontal part 1b2 at a short sidewall 3 of cardinal principle plumbness.Afterwards, the cardinal principle horizontality that is keeping a short sidewall 3, make the supporting pieces h10 that is provided in a positive articulated section H2 on the short sidewall 3, the incision recess h2 that is formed at the cloudy articulated section H1 of the short brink innovation 1b of portion along formation moves downwards, as Figure 11 and shown in Figure 12, on the base plate 1c that roughly all overlaps bottom 1 of the plate-like portion 3b of a short sidewall 3.

Then, another the short sidewall 3 in the vertical short sidewall 3 of relative cardinal principle was fallen to bottom 1 direction, partly overlapped on the short sidewall 3 that has overlapped on the bottom 1 with the cardinal principle horizontality earlier.Same with the short sidewall 3 that above-mentioned elder generation was fallen, the short sidewall 3 of substantially vertical another is in bottom 1 direction is rotated, and the lower edge 3a that is placed on another the short sidewall 3 on the horizontal part 1b2 of the short brink innovation 1b of portion throws off from horizontal part 1b2.Afterwards, keeping another short sidewall 3 to be the cardinal principle horizontality, supporting pieces h10a of being provided in the positive articulated section H2 on another short sidewall 3 is moved downwards along being formed in the incision recess h2 that the short brink innovation 1b of portion goes up the cloudy articulated section H1 that forms, as Figure 11 or shown in Figure 12, short sidewall 3 cardinal principle on even keels were fallen, on the mutual short sidewall 3 of partly overlapping of formerly being fallen.

As mentioned above, as Fig. 3, Figure 11 and shown in Figure 12, owing to being fallen with partly overlapping each other, a pair of short sidewall 3 cardinal principle on even keels that fell overlapped on the bottom 1, therefore can reduce the height of the Collapsible container of folded state, be lower than present Collapsible container with the overlapping a pair of short sidewall 3 of heeling condition.Thereby, accommodate efficient in the time of can improving lamination and accommodate the Collapsible container of folded state.

Above-mentioned relative short sidewall 3 fell overlap on the bottom 1 after, a longer sidewall 2 among the vertical relative long sidewall 2 of cardinal principle was fallen to bottom 1 direction, overlap on the back short sidewall 3 that was fallen among the relative short sidewall 3.In bottom 1 direction was rotated, the lower edge 2a that is placed on a long sidewall 2 on the horizontal part 1a2 of the long side innovation 1a of portion threw off from horizontal part 1a2 at a long sidewall 2 of cardinal principle plumbness.Afterwards, keeping a long sidewall 2 to be the cardinal principle horizontality, the supporting pieces h10 that is provided in a positive articulated section H2 on the long sidewall 2 is moved downwards along the incision recess h2 that is formed in the last cloudy articulated section H1 that forms of the long side innovation 1a of portion, as shown in Figure 8, the long sidewall 2 of a side is overlapped to horizontality on the short sidewall 3 that was fallen above-mentioned back substantially.

Then, another the long sidewall 2 among the vertical long sidewall 2 of relative cardinal principle fell to bottom direction, on the long sidewall 2 of partly overlapping cardinal principle horizontality of formerly being fallen.Fallen with above-mentioned elder generation one long sidewall 2 is identical, and in bottom 1 direction was rotated, the lower edge 2a that is placed on another the long sidewall 2 on the horizontal part 1a2 of the long side innovation 1a of portion also threw off from horizontal part 1a2 at another long sidewall 2 of cardinal principle plumbness.Afterwards, keeping another long sidewall 2 to be the cardinal principle horizontality, the supporting pieces h10 that is provided in the positive articulated section H2 on another long sidewall 2 is moved downwards along the incision recess h2 that is formed in the last cloudy articulated section H1 that forms of the long side innovation 1a of portion, as Fig. 3 and shown in Figure 8, another long sidewall 2 cardinal principle horizontality ground, on the long sidewall 2 that was formerly fallen that fell with overlapping mutually.

As mentioned above, as Fig. 3 and shown in Figure 8, overlapped on the bottom 1 owing to can fall to horizontality a pair of long sidewall 2 that fell substantially with partly overlapping each other, therefore, can reduce the height of the Collapsible container of folded state, be lower than present Collapsible container with the overlapping a pair of long sidewall 2 of heeling condition.Thereby, accommodate efficient in the time of can improving lamination and accommodate the Collapsible container of folded state.

As mentioned above, can the relative short sidewall 3 cardinal principle on even keels that be fallen earlier be fallen from the state that is assembled into case, partly overlapping mutually; Simultaneously can after the relative long sidewall 2 that fell also the cardinal principle on even keel fell, partly overlapping mutually.Thereby, can reduce the height of the Collapsible container of folded state, thereby accommodate efficient can improve lamination and accommodate the Collapsible container of folded state the time.

According to above-mentioned structure, can reduce the height of the Collapsible container of folded state.Be assembled into the state of case, when holding long sidewall 2 or short sidewall 3, in the time of upwards carrying the Collapsible container that is assembled into case, as mentioned above, bottom 1 former state is motionless, and only long sidewall 2 and short sidewall 3 leave bottom 1 and move up.

Below, prevent above-mentioned long sidewall 2 and short sidewall 3 mechanism that 1 disengagement is upwards become flexible from the bottom with reference to Fig. 9, Figure 10, Figure 14 and Figure 15 explanation.

By cutting, bight through hole 1d is set by the inboard vertical component effect 1b1 of the short brink innovation 1b of portion that constitutes bottom 1 and the bight that horizontal part 1b2 constitutes.In addition, be positioned at the upwards loosening teat 1e that prevents that vertical component effect 1b1 direction extension to the inside is set on horizontal part 1b2 bight through hole 1d, that constitute the short brink innovation 1b of portion or the 1b3 of outside vertical portion.What set in bight through hole 1d and this bight through hole 1d prevents upwards loosening teat 1e, forms one or more along the length direction of the short brink innovation 1b of portion.In addition,, be illustrated in the bight through hole 1d, separate the interval of regulation, form two examples that prevent upwards loosening teat 1e at present embodiment.In addition, prevent that the upwards loosening following 1e1 of protuberance 1e that prevents from forming tabular surface, simultaneously, above 1e2 from the 1b3 of outside vertical portion of short brink end 1b vertical component effect 1b1 to the inside, form downward-sloping dip plane.

On the other hand, at the back side of the lower edge 3a of short sidewall 3, what be provided with on the horizontal part 1b2 of the corresponding short brink innovation 1b of portion in above-mentioned bottom 1 prevents upwards loosening teat 1e, be provided with prevent upwards loosening with link 8.This link 8 constitutes to the connecting portion 8b of the level of the short brink innovation 1b of portion of bottom 1 direction extension by the vertical component effect 8a lower end of extending downwards from the back side of lower edge 3a with from vertical component effect 8a.In addition, 8c is the enhancing rib that connects the substantial middle portion of the substantial middle portion of lower edge 3a, vertical component effect 8a and connecting portion 8b respectively.

The short sidewall 3 of as shown in figure 14 cardinal principle horizontality when vertically upright substantially, the short brink that upwards loosening connecting portion 8b with link 8 is inserted in bottom 1 that prevents at the back side that is arranged on the lower edge 3a of short sidewall 3 is gone up in the bight through hole 1d of formation as the 1b of portion, simultaneously, practically be formed at bight through hole 1d in prevent that upwards the following 1e1 of loosening teat 1e contacts.Thereby, even upwards mention the short sidewall 3 of the state of vertical stand-up substantially, the upwards loosening connecting portion 8b that prevents that establishes because hang down on the back side of weak point sidewall 3 lower edge 3a with link 8, the reality following 1e1 that prevent upwards loosening teat 1e interior with being formed at bight through hole 1d contacts, and 1 disengagement moves up from the bottom so can prevent short sidewall 3.

When the assembling Collapsible container becomes box-shaped, as mentioned above, because the chimeric protruding 7a of formation is entrenched in the through hole 4a in the connection box 4 of being located at long sidewall 2 in the connection box 7 of short sidewall 3, thereby, even upwards carry vertically upright substantially long sidewall 2, because the chimeric protruding 7a of formation is entrenched in the through hole 4a in the connection box 4 of being located at long sidewall 2 in the connection box 7 of short sidewall 3, on the back side of short sidewall 3 lower edge 3a, be provided with simultaneously prevent upwards loosening connecting portion 8b with link 8 actual be formed at bight through hole 1d in prevent that 1e1 contact below the upwards loosening teat 1e, so long sidewall 2 can be from the bottom 1 disengagement make progress and become flexible.

In addition, in the above-described embodiment, represented on the short brink innovation 1b of portion of bottom 1 to form bight through hole 1d and prevented upwards loosening teat 1e, and on the back side of the lower edge 3a of short sidewall 3, formed and prevent upwards loosening example with link 8.Yet, also can on the short brink innovation 1b of portion of bottom 1, not set such bight through hole 1d and prevent the upwards loosening protuberance 1e that uses, and on the long side innovation 1a of portion of bottom 1, form same bight through hole 1d and prevent upwards loosening teat 1e, and, on the back side of the lower edge 2a of long sidewall 2, form prevent upwards loosening with link 8.In addition, also can all form bight through hole 1d on the long side innovation 1a of portion of the short brink innovation 1b of portion of bottom 1 and bottom 1 and prevent the upwards loosening protuberance 1e that use, on long sidewall 2 and short sidewall 3, all forming prevents to make progress becomes flexible and uses link 8.

As mentioned above, during the short sidewall 3 cardinal principle vertical stand-ups of cardinal principle horizontality, usually the upwards loosening connecting portion 8b with link 8 that prevents that is located on the back side of lower edge 3a of short sidewall 3 inserts in the bight through hole 1d on the short brink innovation 1b of portion that is formed at bottom 1, actual simultaneously be formed at bight through hole 1d in the following 1e1 that becomes flexible teat 1e that makes progress of preventing contact., when the short sidewall 3 cardinal principle vertical stand-ups of cardinal principle horizontality, if upwards excessively draw short sidewall 3, the loosening connecting portion 8b with link 8 that then prevents to make progress can be placed on and prevent from upwards to become flexible on the top 1e2 of teat 1e.As above-mentioned ground, because preventing upwards loosening top 1e2 with protuberance 1e is from the 1b3 of outside vertical portion of the short brink innovation 1b of portion vertical component effect 1b1 to the inside, form bevelled dip plane downwards, so preventing upwards loosening connecting portion 8b with link 8 descends along this inclination, thereby, prevent upwards loosening connecting portion 8b with link 8 insert be formed at bottom in the bight through hole 1d on 1 the short brink innovation 1b of portion, meanwhile, the actual following 1e1 that prevent upwards loosening teat 1e interior with being formed at bight through hole 1d contacts.

In addition, in the above-described embodiment, illustration such structure, promptly for the height of the Collapsible container that more reduces folded state, make the relative short sidewall that fell earlier 3 substantially horizontalitys fell, partly overlapping mutually, simultaneously, the relative long sidewall 2 that fell after making substantially horizontalitys fell, partly overlapping mutually.But, only also can form any pair of sidewalls in relative short sidewall 3 or the relative long sidewall 2 substantially on even keel fell, partly overlapping such structure mutually.Like this, compare, although the height of the Collapsible container of folded state increases with the above embodiments, but, as mentioned above, the situation that all tilts to fall with relative short sidewall 3 and relative long sidewall 2 relatively can reduce the height of the Collapsible container of folded state.
