First embodiment

The embodiment of the present invention provides a kind of packing box for straight lamp D, shown in reference Fig. 1, Fig. 2, Packing box includes that middle box 10, middle box 10 are suitable to wrap up at least two straight lamp D.Wherein, straight lamp D Can be that any one has the lamp of straight pipe shape, light fixture or a lamp socket, such as LED daylight lamp, light fixture or Lamp socket.

Middle box 10 mainly wraps up straight lamp D with the integrally formed bending design of individual millboard, thus to directly Spot D is protected by.The material of middle box 10 can be selected for but is not limited to monolayer corrugated paper.As it is shown on figure 3, Inner sleeve 20 can also be included between straight lamp D and middle box 10.But, in other embodiments, Straight lamp D can individually be accommodated in middle box 10, it is not necessary to has inner sleeve 20.

Shown in Fig. 3, Fig. 4, middle box 10 includes the supporting region 11 of X arrangement in the width direction, and Lay respectively at the bent area 12 of the both sides of supporting region 11, the length direction of width X and straight lamp D Vertically.Wherein, bent area 12 is suitable to bend towards supporting region 11, and after bending with supporting region 11 shape One-tenth can be wrapped circumferentially around at least one receiving chamber 10a (Fig. 1) of a straight lamp D.As it is shown on figure 3, The inner peripheral surface of inner sleeve 20 contacts with the outer peripheral face of straight lamp D so that straight lamp D is clamped in receiving chamber 10a In.It is to say, an inner sleeve 20 is for accommodating a straight lamp D.But, other embodiment party In formula, straight lamp D can individually be accommodated in middle box 10, it is not necessary to has inner sleeve 20, say, that The each sidewall all outer peripheral faces with straight lamp D accommodating chamber 10a contact so that straight lamp D is clamped in appearance Receive in the 10a of chamber.

Need exist for explanation, when straight lamp D is cased with inner sleeve 20, accommodate each sidewall of chamber 10a Contact with the outer peripheral face of inner sleeve 20.In the following description of the present embodiment, accommodate chamber 10a with straight describing During the matching relationship of spot D, as a example by all the outer peripheral face by its sidewall with straight lamp D contacts.

In other embodiment of the present invention, accommodate each sidewall of chamber 10a not with straight lamp D outside Circumferential contact, includes buffer structure (not shown) between the outer peripheral face of straight lamp D and the sidewall of receiving chamber 10a, Padded coaming makes straight lamp D card be tightly fixed in receiving chamber 10a.Wherein, buffer structure can be example Such as bubble cloth, bubble bags, Shu Meibu, Shu Mei bag, PE Foam (EPE) or air column bag etc..

As shown in Figures 1 to 4, after the bending of bent area 12, there is multiple bending side, as label a in figure, b, C indication.Any one sidewall being formed as accommodating chamber 10a in bending side a, b and c.As it has been described above, In the present embodiment, accommodate chamber 10a by bent area 12 and supporting region 11 around being formed, supporting region 11 also shape Become the sidewall accommodating chamber 10a.

In the present embodiment, during forming receiving chamber 10a, supporting region 11 is without bending.

Wherein, receiving chamber 10a is regular polygon along the projection of described length direction, i.e. accommodates the horizontal stroke of chamber 10a Cross section is regular polygon, and wherein the number on the limit of regular polygon may be greater than the random natural number equal to 3. In the present embodiment, as a example by regular polygon is as tetragon.As shown in Figures 1 to 4, bent area 12 has three Individual bending side a, b and c, wherein three limits of tetragon lay respectively on three bending sides a, b and c, An other limit is then positioned on supporting region 11.Owing to the both sides of supporting region 11 width X are equipped with curved Folding area 12, each bent area 12 all surround with supporting region 11 after bending one accommodate chamber 10a, therefore, The centrage (dotted line in Fig. 3, Fig. 4) of supporting region 11 X in the width direction is that boundary is divided into two parts, this Two parts are respectively as two sidewalls accommodating chamber 10a.In the present invention " regular polygon " be meant that each The difference of the length of side is less than 10%.

As in figure 2 it is shown, when straight lamp D is placed in receiving chamber 10a, the four edges of square is equal Contacting with the outer peripheral face of straight lamp D, each edge of square is roughly the same with the diameter of straight lamp D. In present embodiment " roughly the same " the diameter length difference being meant that each edge length of side and straight lamp D Less than 20%.

In further embodiments, the cross section accommodating chamber 10a can be triangle, pentagon, six limits The arbitrarily regular polygon such as shape, heptagon or octagon.As shown in Figure 5 a, the cross section accommodating chamber 10a is Positive triangle, correspondingly, bent area 12 forms two bending sides a, c after bending, when straight lamp D is put Putting when accommodating in the 10a of chamber, three limits of positive triangle the most all outer peripheral faces with straight lamp D contact, just The each edge of triangle is all higher than the diameter of straight lamp D；As shown in Figure 6 a, the cross section of chamber 10a is accommodated For regular pentagon, correspondingly, bent area 12 forms four bending sides a, b, c, d after bending, when directly When spot D is placed in receiving chamber 10a, each edge of regular pentagon all connects in the outer peripheral face of straight lamp D Touch, but the length of regular pentagon each edge is respectively less than the diameter of straight lamp D；As shown in Figure 7a, accommodate The cross section of chamber 10a is regular hexagon, correspondingly, bent area 12 formed after bending five bending side a, B, c, d, e, same, each edge all contacts in the outer peripheral face of straight lamp D, and the length of each edge It is respectively less than the diameter of straight lamp D；As shown in Figure 8 a, the cross section accommodating chamber 10a is octagon, phase Ying Di, bent area 12 forms seven bending sides a, b, c, d, e, f, g after bending, same, Each edge all outer peripheral faces with straight lamp D contact, and the length of each edge is respectively less than the diameter of straight lamp D. Described in embodiment of above, the limit number of the transverse polygonal of receiving chamber 10a and bent area 12 are after bending The face number difference forming bending side is 1.

By that analogy, accommodating the cross section of chamber 10a, i.e. it is formed along the projection of described length direction Regular polygon can also is that other regular polygons, no longer enumerates at this.The polygonal each edge length of side With the direct path correlation of straight lamp D it is: each edge of positive triangle is all higher than the diameter of straight lamp D, just The each edge of tetragon is roughly the same with the diameter of straight lamp D, the length of regular pentagon each edge is respectively less than The diameter of straight lamp D, the length of regular hexagon each edge is respectively less than the diameter of straight lamp D, regular hexagon The length of each edge less than the length of regular pentagon each edge, by that analogy.

In the present embodiment, as shown in Figure 1, Figure 2 and Figure 3, the bent area 12 of supporting region 11 both sides it is positioned at About supporting region 11 symmetrically, two the receiving chambeies formed after bending also about supporting region 11 along width The centrage in direction is symmetrical.

In further embodiments, the bent area 12 being positioned at supporting region 11 both sides can also be asymmetric, Correspondingly, two the receiving chambeies formed after bending are the most asymmetric.Such as, as it is shown in figure 9, be positioned at carrying The bent area 12 of both sides, district 11 size in the width direction is different, both after the bending of same number, The receiving chamber 10a varied in size is surrounded respectively, to accommodate the straight lamp of different-diameter, example with supporting region 11 A diameter of 31.8mm, T8 fluorescent tube a diameter of such as a diameter of 38.1mm, the T10 fluorescent tube of T12 fluorescent tube The diameter of a diameter of 12.7mm, the T2 fluorescent tube of a diameter of 16mm, the T4 fluorescent tube of 25.4mm, T5 fluorescent tube For 6.4mm.For another example, the bent area 12 being positioned at supporting region 11 X both sides in the width direction can each lead to Cross the bending of different number of times so that two accommodate chamber and have different shapes.Such as, as shown in Figure 10, Two accommodate chamber 10a and are respectively equilateral triangle and square, or two along the projection of described length direction Individual receiving chamber 10a projection along its length can also is that other regular polygons, but two regular polygons The number on limit different.

Again pointing out, " regular polygon " in the present embodiment, the difference referring to each length of side is less than The polygon of 10%.

With continued reference to Fig. 1 and combine shown in Fig. 3, bent area 12 has free end c1, after bending, extremely The free end c1 of a few bent area 12 engages with supporting region 11, can be at fully circumferential parcel with formation One straight lamp D accommodates chamber 10a.When free end c1 engages with supporting region 11, accommodate chamber 10a in week Upwards closing, straight lamp D circumferentially direction is completely wrapped in receiving chamber 10a.

In order to meet the purpose that free end c1 engages with supporting region 11, as it is shown on figure 3, to be bent to form two As a example by the receiving chamber of individual square, before bending, the width of middle box 10 is preferably 8 times of straight lamp D Add the thickness of cardboard own 2 times, so can be only achieved fully wrapped around protected effect；Middle box 10 exists The length direction of straight lamp D is then not less than the length of straight lamp D, with at the fully wrapped around straight tube of length direction Lamp D.

Such as Fig. 3, during packaging, choose two straight lamp D, be placed side by side for spacing with 2 times of calliper The centre of supporting region 11, then carries out three 90 ° curved by each bent area 12 along the circumference of straight lamp D Two bent area 12 outermost bending side c, the last time after bending, are folded into two directly by folding simultaneously In spacing between spot D, two bent area 12 outermost bending side c mutually overlap.Such as Fig. 5 a, As a example by the receiving chamber being bent to form two positive triangles, before bending, the width of middle box 10 is preferably 6 The positive triangle length of side again, both sides free end c1 and supporting region 11 are bonded between two straight lamp D In spacing, two bent area 12 outermost bending side c the most mutually overlap, and middle box 10 is at straight lamp D Length direction then not less than the length of straight lamp D, with at length direction fully wrapped around straight lamp D.As Fig. 6 a, Fig. 7 a and Fig. 8 a, to be bent to form two regular pentagons, regular hexagon, the receiving of octagon As a example by chamber, before bending, the width L of middle box 10 is preferably for be multiplied by more than 2 times of regular polygon limit number n again Regular polygon length of side l adds 2 times of the own thickness h of cardboard, i.e. L > 2nl+2h.Both sides free end c1 And supporting region 11 is bonded in the spacing between two straight lamp D, two bent areas 12 are outermost curved Folding face c the most mutually overlaps, middle box 10 at the length direction of straight lamp D then not less than the length of straight lamp D, With at length direction fully wrapped around straight lamp D.

Wherein it should be noted that in Fig. 5, cross section is the freedom of two receiving chamber 10a of positive triangle When end c1 engages with supporting region 11, two free end c1 are immediately adjacent to each other.In Fig. 6 a, Fig. 7 a and Fig. 8 a, Cross section is regular pentagon, hexagon and octagonal two free end c1 accommodating chamber 10a and supporting region 11 During joint, between two free end c1, there is interval.Should be appreciated that in Fig. 5, two free end c1 Interval can also be provided with.

In further embodiments, bent area 12, can between free end c1 and supporting region 11 after bending To have gap (as shown in label G in Fig. 1 b, Fig. 5 b, Fig. 6 b, Fig. 7 b, Fig. 8 b).In other words, Receiving chamber 10a has opening G, straight lamp D circumferentially direction in the circumferential and is not completely wrapped in appearance Receive in intracavity 10a, and outside having sub-fraction to be exposed to.Be appreciated that Fig. 1 b, Fig. 5 b, Fig. 6 b, In the embodiment of Fig. 7 b and Fig. 8 b, the length of side of bent area 12 outermost bending side c can adjust, Accommodating the cross section of chamber 10a, i.e. it forms class regular polygon, outermost along the projection of described length direction The length of side of bending side c with the direct path correlation of straight lamp D be: the outermost bending side of the positive triangle of class The length of side of c can more than/less than or roughly the same with the diameter of straight lamp D, class square is outermost The length of side of bending side c can less than straight lamp D diameter or roughly the same with the diameter of straight lamp D, The length of regular pentagon outermost bending side c is respectively less than the diameter of straight lamp D, regular hexagon outermost The length of bending side c be respectively less than the diameter of straight lamp D, by that analogy.

In further embodiments, such as Fig. 4 b, middle box 10 can offer one or many in the centre of cardboard Individual hole 10b, so, after cardboard creasing forms middle box 10, the perisporium of middle box 10 will have one or Multiple through holes, these through holes will expose the portion perimeter face of straight lamp D, say, that user is from the outside Through through hole it can be seen that the portion perimeter face of straight lamp D.It should be noted that after providing holes 10b, The globality of box 10 in needing to ensure, any hole 10b all middle box 10a can not be isolated and become two or Some.

In the present embodiment, as shown in Figure 1 and Figure 2, the bent area 12 of supporting region 11 both sides it is positioned in carrying Surface, the same side bending in district 11.

In further embodiments, the bent area 12 difference at supporting region 11 of supporting region 11 both sides it is positioned at Side surface bends.As a example by square, as shown in Figure 11, Figure 12, one of them bent area 12 court Bending to the upper surface of supporting region 11, its receiving chamber 10a surrounded with supporting region 11 is positioned at supporting region 11 Upper surface；Another bent area 12 bends towards the lower surface of supporting region 11, and it surrounds with supporting region 11 Receiving chamber 10a be positioned at the lower surface of supporting region 11.In the process, supporting region 11 is without bending.

Wherein, when bent area 12 is towards the different surfaces bending of supporting region 11, supporting region 11 is being ensured In the case of bending, appearance can be adjusted by the size changing bent area 12 X in the width direction Receive the size of chamber 10a.As shown in figure 13, as a example by square, when the width of bent area 12 is enough Time big, its free end c1 can engage with the other end of supporting region 11 X in the width direction after bending, So that increase the size accommodating chamber 10a to greatest extent.In the process, supporting region 11 is without curved Folding.In embodiment as a example by square, the width of supporting region 11 is preferably the straight of straight lamp D 2 times of the own thickness of cardboard are added in footpath.In other embodiments, accommodate the cross section of chamber 10a, Its regular polygon formed along the projection of described length direction i.e., the width of supporting region 11 is the most permissible Roughly the same with the regular polygon length of side.

In further embodiments, bent area 12 is suitable to by being bent to form multiple X in the width direction arrangement Receiving chamber 10a.As shown in figure 14, as a example by square, in Figure 14, dotted line represents supporting region 11 The center of X in the width direction, each bent area 12 bends and is formed multiple appearance towards supporting region 11 Receive chamber 10a.Figure 14 schematically illustrates each bent area 12 and is bent to form two receiving chamber 10a's Situation.As long as should be appreciated that the size long enough of bent area 12 X in the width direction, accommodate chamber 10a's Number can also be more.

Further, with reference to shown in Figure 15, Figure 16, in accommodating chamber 10a, at least one protection knot it is provided with Structure 13, safeguard structure 13 offsets for the end with straight lamp D, to prevent straight lamp D along length side Chamber 10a is accommodated to departing from.

In the present embodiment, as shown in Figure 16 a, Figure 16 b, accommodate chamber 10a high in end along its length Going out the end of straight lamp D, safeguard structure 13 is located in the raised area accommodating chamber 10a.It is to say, The length accommodating chamber 10a is greater than the length of straight lamp D, and straight lamp is completely covered at length direction D.The end of straight lamp D length direction is located at by safeguard structure 13, to enter straight lamp D at length direction Row is spacing.Wherein, as shown in fig 16b, between length Ld of the straight lamp D end face with two ends lamp holder Distance defines, and does not comprise the guide pin D1 on lamp holder, and correspondingly, the end of straight lamp D refers to lamp holder End face D2.

Specifically, such as Figure 15, Figure 16, safeguard structure 13 is formed at adjacent first accommodating chamber 10a In sidewall a, the second sidewall b.Wherein, the first side wall a, the second sidewall b i.e. bent area 12 adjacent two Individual bending side a, b, point to same position, and simply title is different.

Safeguard structure 13 includes: the most spaced two limits, be respectively defined as the first limit 13a, Second limit 13b, the first limit 13a, the second limit 13b are all across the first side wall a, the second sidewall b, and in institute Severing on sidewall.

After Figure 16, the first limit 13a, the second limit 13b severing, between the first limit 13a, the second limit 13b Region form reverse bent area 13 ＇, the two ends of reverse bent area 13 ＇ X in the width direction have and are positioned at The first border a ＇ in the first side wall a, and the second boundary b ＇ being positioned in the second sidewall b.The most curved Folding area 13 ＇ is towards the internal bend of receiving chamber 10a, and shape at the first border a ＇, the second boundary b ＇ Become folding line.Reversely after bent area 13 ＇ bending, form the safeguard structure 13 shown in Figure 15.

With continued reference to Figure 15, shown in 16, between the first side wall a, the second sidewall b, there is the first flanging 121. Reversely include two bending sides after bent area 13 ＇ bending, be respectively defined as the first bending side 131, second Bending side 132, has the second flanging 133 between first bending side the 131, second bending side 132.

In the present embodiment, before bending, the second flanging 133 is located along the same line with the first flanging 121. As shown in figure 16, when bent area 12 does not bends, first flanging the 121, second flanging 133 overlaps.Thus Form safeguard structure 13 as shown in figure 15, this safeguard structure 13 along its length be projected as square.

As shown in figure 16, between can having between the edge of the end of reverse bent area 13 ＇ and middle box 10 Every or not interval.As illustrated in fig 16 a, reverse bent area 13 ＇ and middle box edge along its length Between there is a certain distance H, thus the end of safeguard structure 13 with middle box 10 is separated, to such an extent as to Central box 10, when the shock that end is subject to, can first be absorbed a part of impact force by end so that clashes into Power will not completely be moved and is delivered to safeguard structure 13, thus appropriateness cuts down the impact force that straight lamp D is subject to, and keeps away Exempt from it to be damaged.Wherein, reverse bent area 13 ＇ (i.e. safeguard structure 13) length along its length L1 in the range of 1cm to 3cm, preferably 2cm.More precisely, such as Figure 16, reverse bent area Spacing distance between the first limit 13a of 13 ＇, the second limit 13b is 1cm to 3cm, preferably 2cm. If reversely the length of bent area 13 ＇ is the shortest, insufficient strength, cannot firmly prop up lamp holder, oversize then Will result in the waste of cardboard.

As it was previously stated, receiving chamber 10a is located at by safeguard structure 13 exceeds the part of straight lamp D along its length, So that the size that safeguard structure 13 is along its length meets above-mentioned requirements, then, in the present embodiment, The raised area of receiving chamber 10a length range along its length is more than reverse bent area 13 ＇ along length side To the scope of length L1.

It addition, reversely the limit of bent area 13 ＇ is vertical with length direction.As Figure 16, the first limit 13a, Two limit 13b are all vertical in length direction.So, after reverse bent area 13 ＇ bends, safeguard structure is formed When 13, safeguard structure 13 end face along its length is parallel with the end face of straight lamp D, so that two There is between end face bigger contact area, strengthen the safeguard structure 13 position-limiting action to straight lamp D.

Such as Figure 16, the forming method of safeguard structure 13 is as follows:

First on middle box 10, reserve the straight lamp D accommodation space at length direction, then at accommodation space The two ends along straight lamp D length direction, cut out between the first side wall a and the second sidewall b the most curved The first limit 13a of folding area 13 ＇, the second limit 13b；Then, reverse bent area 13 ＇ is pressed, by it to appearance Receive the internal bend 90 ° of chamber 10a, to form one firm safeguard structure 13.Such as Figure 15, Mei Gerong The chamber 10a that receives is equipped with safeguard structure 13 in the end of straight lamp D so that in middle box 10 every the most always Spot D all can appropriateness be protected, not impaired because of carrying.

In further embodiments, as shown in Figure 17, Figure 18, before bending, the second flanging 133 and One flanging 121 X in the width direction has interval, and the i.e. second flanging 133 is misaligned with the first flanging 121. Being consequently formed safeguard structure 13 as shown in figure 18, this safeguard structure 13 is being projected as along its length Rectangle.

In further embodiments, the edge weight of the end of a limit of reverse bent area 13 ＇ and middle box 10 Close.As shown in figure 19, the first limit 13a of reverse bent area 13 ＇ overlaps with the broadside of middle box 10, by This outer face of safeguard structure 13 formed overlaps with the end face of middle box 10.Should be appreciated that the most reverse Bent area 13 ＇ needs the limit only one of which of severing, the i.e. second limit 13b.In this case, with Middle box 10 packs straight lamp D when the height of 1 meter carries out drop test, although safeguard structure 13 Length alreadys more than 5cm, but when central box 10 strikes ground along the end of described length direction, hits Straight lamp D still can be caused serious injury by the power hit, and test result finds, safeguard structure 13 Length L1 at least needs to reach 10cm and just can ensure that straight lamp D will not damage, say, that the most curved Folding area 13 ＇ (i.e. safeguard structure 13) length L1 along its length is not less than 10cm, is at this moment accomplished by Suitably increase the size accommodating the part that chamber 10a exceeds straight lamp D at length direction.It should be understood that The raised area of receiving chamber 10a length range along its length is greater than or equal to reverse bent area 13 ＇ Length, do not have spaced embodiment equal to reverse a length of of bent area 13 ＇, more than reversely bending The a length of spaced embodiment of district 13 ＇, in spaced embodiment, both differences the biggest generation Table interval (distance H) length is the longest.The raised area length along its length is the longest, during the shock being subject to, The effect of impact force can be absorbed better, the sad waste that will also result in cardboard.

It should be noted that the one end at straight lamp D, reverse bent area 13 ＇ can arrange one or Multiple, to form one or more safeguard structure 13.When reverse bent area 13 ＇ has at least two, Should be respectively arranged in different adjacent sidewalls, sidewall therein may be located at bent area 12, it is also possible to It is positioned at supporting region 11.As shown in figure 20, between supporting region 11 and the first side wall a, it also is provided with one prevent Protection structure 13.By that analogy, the quantity of safeguard structure 13 can also be more, and can be according to not similar shape The receiving chamber on-demand layout of 10a of shape.

Further, with continued reference to Figure 15, reverse bent area 13 ＇ after bending with the first side wall a, Two sidewall b surround the safeguard structure 13 of tetragon.Along the radial direction of straight lamp D, this tetragon covers The size of straight lamp D accounts for 3rd/to four/4th of straight lamp D diameter, and optimum size is two/ One.This size is the shortest, cannot really prop up the lamp holder of straight lamp D, oversize, and middle box 10 cannot form heavily fortified point Solid safeguard structure, it is impossible to actually reach protection straight lamp D purpose.

It addition, the two ends that straight lamp D is along its length all can arrange safeguard structure 13 so that straight lamp D is clamped between safeguard structure 13 at length direction.Due to middle box 10 two ends safeguard structure 13 away from From being to set with the length of straight lamp D, therefore the safeguard structure 13 at two ends can just prop up straight lamp The lamp holder at D two ends, to be firmly limited to the inside of middle box 10 by straight lamp D.

Further, with continued reference to Fig. 4 and combine shown in Figure 21, shown, middle box 10 also includes connecting Structure 14, attachment structure 14 is for fixing the receiving chamber 10a of both sides, to prevent from accommodating chamber 10a again Launch.

Second embodiment

The present embodiment is with the difference of first embodiment, in first embodiment, accommodates chamber 10a being formed During, supporting region 11 is without bending, but in the present embodiment, supporting region 11 is through bending.

With reference to shown in Figure 25, supporting region 11 has the flanging 111 of the length direction extension along straight lamp D, Supporting region 11 can be bent along flanging 111.

Wherein, the purpose that supporting region 11 bends along flanging 111 has two kinds: the first, by supporting region 11 Bending change the arrangement mode accommodated between the 10a of chamber；The second, supporting region 11 can be along flanging 111 Bending forms receiving chamber 10a.

(1) the first is described below: changed the row accommodated between the 10a of chamber by the bending of supporting region 11 Mode for cloth.

In this case, supporting region 11 is before bending, and each accommodates chamber 10a and has been formed, supporting region The bending of 11 is only used for changing the arrangement mode accommodated between the 10a of chamber, but do not change accommodate chamber shape or Person and the number of sidewall.

As a example by the cross section container 10a as square, Figure 26 schematically illustrates by bending Supporting region 11 changes a kind of form of the arrangement mode accommodated between the 10a of chamber.As shown in figure 26, carrying Before district 11 bending, the bent area 12 being positioned at supporting region 11 both sides bends at the not same surface of supporting region 11. As a example by square, one of them bent area 12 towards supporting region 11 upper surface bend, its with hold The receiving chamber 10a that load district 11 surrounds is positioned at the upper surface of supporting region 11；Another bent area 12 is towards carrying The lower surface bending in district 11, its receiving chamber 10a surrounded with supporting region 11 is positioned at the following table of supporting region 11 Face, two accommodate chamber 10a in angular distribution (Figure 26 a), after supporting region 11 bends along flanging, two appearances The chamber 10a that receives is distributed (Figure 26 b) side by side, wherein accommodates the 3rd sidewall c and the carrying of opposite side of chamber 10a District 11 is bonded to each other.In further embodiments, the bent area 12 of supporting region 11 both sides it is positioned in carrying The same surface bending in district 11.With reference to Figure 26 c, 26d, as a example by square, such as Figure 26 c, carrying Before district 11 bending, one of them bent area 12 bends towards the upper surface of supporting region 11, itself and supporting region The receiving chamber 10a that 11 surround is positioned at the upper surface of supporting region 11；Another bent area 12 is also towards supporting region The upper surface bending of 11, its receiving chamber 10a surrounded with supporting region 11 is also positioned at the upper table of supporting region 11 Face, two receiving chamber 10a are in being distributed side by side, and such as Figure 26 d, supporting region 11 is along its flanging towards lower surface After bending, supporting region 11 is divided into two parts and the most corresponding two receiving chamber 10a, and two accommodate chamber 10a Supporting region 11 bonded to each other.Such as Figure 26 e, for the receiving chamber 10a of other regular polygons, such as positive six limits Shape, the bending that again may be by supporting region 11 changes the arrangement mode accommodated between the 10a of chamber.

As a example by the receiving chamber 10a that cross section is positive triangle, Figure 27 schematically illustrates by bending Supporting region 11 changes the another kind of form of the arrangement mode accommodated between the 10a of chamber.Such as Figure 27 a-27d, Before supporting region 11 bending, two receiving chamber 10a are in be arranged side by side (Figure 27 a, 27c), and supporting region 11 can To make two receiving chamber 10a stacked (Figure 27 a, 27b) after upper surface bending, and make two Sidewall (in figure shown in label c) is bonded to each other；Or, supporting region 11 can also bend towards lower surface Making two to accommodate chamber 10a later and be stacked (Figure 27 c, 27d), now, supporting region 11 is divided into two parts And correspondence two accommodates chamber 10a respectively, two supporting regions 11 accommodating chamber 10a are bonded to each other.As Figure 27 e, 27f, before supporting region 11 bending, two accommodate chamber 10a and lay respectively at two surfaces (27e) of supporting region 11, Supporting region 11 can also be towards any surface bending so that two accommodate chamber 10a and are stacked (Figure 27 f).

Should be appreciated that this mode is equally applicable to the structure that cross section is other regular polygons.And When bent area 12 is by being bent to form multiple receiving chamber 10a arranged in the width direction, the most permissible The arrangement mode accommodated between the 10a of chamber is changed by the bending of supporting region 11.

As can be seen here, supporting region 11 is suitable to be formed bonded to each other between two receiving chamber 10a by bending Sidewall, to change the arrangement mode accommodated between the 10a of chamber.

(2) the second is described below: supporting region 11 can form receiving chamber 10a along flanging 111 bending.

In this case, one of them bent area 12 size in the width direction is less, to such an extent as to carrying District 11 is before bending, and at least one accommodates chamber and is formed the most completely, and such as this receiving chamber is owing to lacking not yet At least one sidewall and the structure that be enough to wrap up straight lamp D can not be formed, in the case, by supporting region 11 bend, and make bending after, formed accommodate chamber 10a sidewall.

Can be divided into the most again following several situation:

Situation one, supporting region 11 can be shared along flanging bending to be formed between the receiving chamber adjacent at two Sidewall.

As a example by the cross section container 10a as square, Figure 28 schematically illustrates supporting region 11 A kind of form accommodating chamber 10a is formed by bending.In Figure 28, supporting region 11 before bending, its In one accommodate chamber 10a ＇ due to disappearance one sidewall and there is opening (Figure 28 a), this receiving chamber 10a ＇ Cannot wrap up straight lamp D, after supporting region 11 bending, this opening will be accommodated a side of chamber 10a by another Wall is closed (this sidewall can be another supporting region 11 accommodating chamber 10a), so that accommodate chamber 10a ＇ Ultimately form the structure (Figure 28 b) that be enough to wrap up straight lamp D.Under end-state, two accommodate chamber 10a Having shared sidewall, in the structure shown in Figure 28 b, the sidewall shared is positioned on supporting region 11.

As a example by the receiving chamber 10a that cross section is positive triangle, Figure 29 schematically illustrates supporting region 11 The another kind of form accommodating chamber 10a is formed by bending.In Figure 29, supporting region 11 before bending, One of them accommodates chamber 10a ＇ and has opening (Figure 29 a) due to one sidewall of disappearance, and this opening is in bending The sidewall being accommodated chamber 10a by another afterwards is closed (Figure 29 b), and described sidewall is on bent area 12. Under end-state, two accommodate chamber 10a and have shared sidewall, in the structure shown in Figure 29 b, share Sidewall be positioned on bent area 12.In another embodiment, one of them accommodate chamber 10a ＇ due to Lacking a sidewall and have opening, this opening is accommodated supporting region 11 institute of chamber 10a by another after bending Close.

Should be appreciated that this mode is equally applicable to the structure that cross section is other regular polygons.

Situation two, supporting region 11 can bend along flanging, is respectively used to adjacent receiving chamber forming two Sidewall.

Being as a example by orthohexagonal receiving chamber by cross section, such as Figure 30, wherein Figure 30 a shows supporting region Structure before 11 bendings, two accommodate chamber 10a and all lack a sidewall.At supporting region 11 along flanging (figure In 30a shown in dotted line) towards black block arrow direction bend after, supporting region 11 divides with flanging for boundary It is two faces, and respectively constitutes two sidewalls accommodating chamber 10a, such as Figure 30 b.

Situation three, supporting region 11 can bend to form at least one sidewall accommodating chamber along flanging, And form shared sidewall between two receiving chambeies.

Being as a example by orthohexagonal receiving chamber by cross section, such as Figure 31, wherein Figure 31 a shows supporting region Structure before 11 bendings, in two adjacent receiving chamber 10a, receiving chamber, left side 10a lacks a sidewall, The receiving chamber 10a on right side lacks two sidewalls.At supporting region 11 along flanging (in Figure 30 a shown in dotted line) After bending towards black block arrow direction, the supporting region 11 two faces with flanging as boundary respectively constitute two The side sidewall of individual receiving chamber 10a, and, the sidewall of receiving chamber, left side 10a is simultaneously as receiving chamber, right side Another sidewall of 10a, and finally make two receiving chamber 10a all form the knot enough wrapping up straight lamp D Structure, such as Figure 31 b.

It should be noted that as in the first embodiment, before supporting region 11 bends, be positioned at supporting region 11 The bent area of both sides can bend on the surface, the same side of supporting region 11, or the difference at supporting region 11 Side surface bends.

3rd embodiment

The present embodiment is with the difference of first embodiment, in the present embodiment, accommodates the sidewall of chamber 10a There is at least two-layer.More precisely, along the circumference of straight lamp D, each receiving chamber 10a has at least The sidewall of two layers bent, and contact at each sidewall all outer peripheral faces with straight lamp D of internal layer, make Obtain straight lamp D to be clamped in the 10a of receiving chamber, place.

Such as Figure 32, as a example by the cross section receiving chamber 10a as square, each receiving chamber 10a has Double wall, the most respectively ground floor wall 101, second layer wall 102.Wherein, ground floor wall 101 Each sidewall all outer peripheral faces with straight lamp D (being not drawn in figure) contact, with by straight lamp D clamping Including.

As it was previously stated, the cross section accommodating chamber 10a can also be other regular polygons, such as positive triangle, Regular hexagon etc..Such as, show that cross section is positive triangle and has double walled receiving chamber such as Figure 33 The structure of 10a.Figure 34 shows that cross section is regular hexagon and has the knot that double walled accommodates chamber 10a Structure.

As shown in Figure 32, Figure 33, Figure 34 and Figure 35, the number of plies of the sidewall of each receiving chamber 10a is identical, It is all two-layer；Shown in Figure 36, the number of plies of the sidewall accommodating chamber 10a differs, but at least two-layer.Should When knowing, no matter accommodate the cross section why shape of chamber 10a, the sidewall of each receiving chamber 10a The number of plies can also is that three layers or more, but straight lamp must be sidewall (the ground floor wall being clamped on innermost layer 101) in the space surrounded.

With continued reference to Figure 32, in two adjacent receiving chamber 10a, one of them accommodates chamber 10a and has the One outer wall W1, another accommodates chamber 10a and has the second outer wall W2；Described first outer wall W1 is with described Second outer wall W2 is bonded to each other.Second outer wall W2 is one of them second layer wall 102 accommodating chamber 10a, Also it is another ground floor wall 101 accommodating chamber 10a simultaneously；First outer wall W1 is that one of them accommodates chamber The ground floor wall 101 of 10a, is also another second layer wall 102 accommodating chamber 10a simultaneously.Such as Figure 32 In embodiment, the second outer wall W2 is the second layer wall 102 that left side accommodates chamber 10a, is also right side simultaneously Accommodate the ground floor wall 101 of chamber 10a；First outer wall W1 is the ground floor wall 101 that left side accommodates chamber 10a, Also it is the second layer wall 102 of right side receiving chamber 10a simultaneously.First outer wall W1 and the second outer wall W2 is two The two-layer sidewall that individual receiving chamber 10a is shared.

As shown in figure 32, along direction from inside to outside, the first outer wall W1, the second outer wall W2 make respectively The second layer wall of chamber 10a is accommodated for another.It is to say, at the first outer wall W1, the second outer wall W2 Before laminating, two accommodate the aspectant sides of chamber 10a respectively only have one layer of sidewall, when the first outer wall W1, After second outer wall W2 laminating, the first outer wall W1, the second outer wall W2 accommodate chamber 10a respectively as another Second layer wall from inside to outside.

Should be appreciated that before the first outer wall W1, the second outer wall W2 laminating, as long as one of them accommodates chamber 10a is only having one layer of sidewall towards another side, it is possible to by the first outer wall W1, the second outer wall The laminating of W2 makes this receiving chamber 10a have a double walled effect, now the first outer wall W1, second One of them in outer wall W2 accommodates the second layer wall from inside to outside of chamber 10a as another.

In structure as shown in figure 32, supporting region 11 without bending, the first outer wall W1, the second outer wall W2 lays respectively in the bent area 12 of supporting region 11 both sides.Wherein, the first outer wall W1, the second outer wall W2 lays respectively at the bending side region at the middle part of bent area, place 12.

In middle box 10 as shown in figure 32, supporting region 11 without bending, the first outer wall W1, second Outer wall W2 is by bonded to each other after the bending of bent area 12.

In further embodiments, supporting region 11 has flanging, the first outer wall W1, the second outer wall W2 By supporting region 11 along flanging bend after bonded to each other.As shown in figure 33, it is positive triangle with cross section Receiving chamber 10a as a example by, supporting region 11 has flanging (position shown in dotted line in figure) in centre, carrying Before district 11 bending, two accommodate the aspectant side of chamber 10a and only have single layer wall (Figure 33 a) respectively, when Supporting region 11 is along figure after the bending of direction shown in black block arrow, and two single layer wall are stacked, to form phase First outer wall W1, the second outer wall W2 of laminating mutually, so that accommodate chamber 10a have double walled knot Structure (Figure 33 b).
