Horizontal joint-cutting facing each other is positioned between time side plate and secondary lid, is starting point with the intersection point of first horizontal fold line and oblique broken line, ends at the intersection point of first horizontal fold line and vertical fold.
Wherein: the angle of described oblique broken line and vertical fold is 45 when spending, and packing container is square little volume receptacle.
Reaching embodiment in conjunction with the accompanying drawings is described in detail as follows architectural feature of the present invention:
Brief description of drawings:
Fig. 1 is the plane outspread drawing that changes the packing container of volume of the present invention;
Fig. 2 is the block diagram that changes the packing container of volume of the present invention, wherein:
Fig. 2 A, 2B are the scheme drawing of large-volume packing container;
Fig. 2 C, 2D are the scheme drawing of little volume packing container.
Please refer to shown in Figure 1ly, it is the plane outspread drawing that changes volume packing container of the present invention, wherein, can roll over planar materials and form by cutting, and impression has array broken line and joint-cutting on it.In the present invention, vessel comprises: side plate group, cover plate group and base plate.The side plate group is in order to form vessel space, and cover plate is by top closed container space, and base plate is by following closed container space.The side plate group comprises double-type master plate 11 (being made up of master plate top 11a and master plate bottom 11b) and double-type side plate 12 (being made up of inferior side plate top 12a and time side plate bottom 12b).The cover plate group comprises double-type main cover plate 8 and double-type secondary lid 7.Base plate 9 autonomous side plate bottom 11b and time side plate bottom 12b extend.There is horizontal fold line 1,2,3 to run through body in addition in addition, vertical fold 4 and oblique broken line 5.The horizontal fold line 1 of oblique broken line more than 5 is provided with horizontal joint-cutting 6.Oblique broken line 5 and horizontal joint-cutting are relative in twos.Body is provided with a junction surface 10.After body was with vertical fold 4 invaginations 90 degree, junction surface 10 engaged with time side plate bottom 12b, makes body surround a rectangular space.At this moment, base plate 9 just can obtain needed container after engaging according to the 90 degree sealings of horizontal fold line 3 invaginations.
As shown in Figure 2, it is the block diagram that changes the packing container of volume of the present invention, according to the container that expansion drawing was folded into of Fig. 1 the methods of two kinds of sealing caps is arranged, to obtain the container of two kinds of different volumes respectively.Shown in Fig. 2 A and 2B, main cover plate 8 and secondary lid 7 obtain a kind of large-volume receptacle according to horizontal fold line 1 invagination, and this is an one.In the time will sealing the container of this big volume, can seal secondary lid 7 earlier, then seal main cover plate 8 again.That is secondary lid 7 is following at this moment, and main cover plate 8 is last.
Shown in Fig. 2 C, 2D, when wishing to get little volume receptacle, main cover plate 8 together with the top 11a of master plate earlier respectively according to horizontal fold line 2, oblique broken line 5 and vertical fold 4 tops to invagination.Afterwards, secondary lid 7 just can obtain the container of little volume according to horizontal fold line 2 invaginations together with the top 12a of inferior side plate.At this moment, last, main cover plate 8 is descending together with master plate top 11a secondary lid 7 together with inferior side plate top 12a.
Be noted that, when making large-volume receptacle,, therefore, can not have the shortcoming of aforementioned structure intensity reduction because joint-cutting 6 on the horizontal fold line 1 between inferior side plate top 12a and the secondary lid 7, can not cause damage to side plate group intensity connected to one another.
In the foregoing description, main cover plate 8 and secondary lid 7 be dimensioned to large-volume receptacle the time master cover plate 8 both front end driving fits, and secondary lid 7 both front end driving fits when little volume receptacle.And the angle of 1,2 of oblique broken line 5 and vertical fold 4 and horizontal fold line need guarantee main cover plate 8 together with master plate top 11a under little volume receptacle, be flattened on during invagination on the plane that is constituted by horizontal fold line 2, it is square could keeping volume.Among the present invention,, can reach above-mentioned requirements when this angle is 45 when spending.
Compared with prior art, the present invention has following effect:
It is practical to understand the packing container that changes volume of the present invention by above-mentioned explanation, can general existing vessel structure not carried out under the more cataclysmal principle, only need several broken line of impression and joint-cutting on vessel, just can reach the purpose that changes vessel volume; And the productive costs of invention packing container is low.Because horizontal joint-cutting can not cause structural infringement, makes container of the present invention can be made into the container of big volume or little volume.
Container of the present invention only need impress the purpose that several broken line and joint-cutting just can reach the change vessel volume on existing vessel under the situation that does not reduce structure of container intensity.The user also only needs the variodenser of design minority different size and is made up utilization just can reach the effect of one-object-many-purposes in order to pack multiple article not of uniform size; More can repeated usage, reduce unnecessary costs such as production Different Package container and repeated packing.
Foregoing is to utilize embodiment that technical characterictic of the present invention is described, is not to be used to limit protection scope of the present invention, even there is the people to change slightly on the basis of the present invention's design, must belong in protection scope of the present invention.
