Description
Technical field
The utility model relates to Paper handbag, relates in particular to a kind of square bottom Paper handbag.
Background technology
The Paper handbag that uses in the market except plastic tape, uses maximum paper bags that is.And along with the enhancing of whole mankind's environmental consciousness and the appearance of national relevant policies rules, the scope of application of Paper handbag and occupation rate of market present the trend of rising, are the at first mode of packing in future.
China Patent No. be 2006201546205X, Granted publication day are December 19 in 2007 day, be called in the patent documentation of " tealeaves Paper handbag " and disclose a kind of Paper handbag.The bag of paper bag is four prism type square bottom structure.
The developed surface of the bag of such Paper handbag is as described in Figure 1: comprise the left wall 12, rear wall 13, right wall 14, antetheca 15, the applying limit 19 that are partitioned into by perpendicular rib 11 and basal edge 21, be connected to left egative film 22 on the left wall 12, be connected to rear egative film 23 on the rear wall 13, be connected to the right egative film 24 on the right wall 14 and be connected to front egative film 25 on the antetheca 15, the centre of left wall 12 and right wall 14 all is provided with the first broken line 16 that extends along the short transverse of bag, respectively is provided with two the second broken lines 17 that intersect vertically on left wall 12 and the right wall 14.All be provided with two on front egative film 25 and the rear egative film 23 with the 5th broken line 26 at basal edge 21 angles at 45 °, left wall 12, rear wall 13, right wall 14, antetheca 15 are provided with four fold line 18.
Referring to Fig. 2, the method for moulding bag 1 is that left wall 12, rear wall 13, right wall 14, antetheca 15 are encircled into the bag body 1 of four prism type along perpendicular rib 11 bendings.Left egative film 22, rear egative film 23, right egative film 24 and front egative film 25 are formed diapire 2 along basal edge 21 towards the internal bend of bag 1.Front egative film 25 and rear egative film 23 are folded into part along the 5th broken line 26 and are superimposed together.
Referring to Fig. 3, when bag was superimposed together, diapire 2 was in straight configuration and is folded into take four fold line 18 as axle with antetheca 15 parts and is superimposed together.Certainly stack also passable with rear wall 13.
The above version of existing bag has the following disadvantages: front egative film and rear egative film are in partially folded state, cause the poor flatness of diapire, and outward appearance is not attractive in appearance, affects the market competitiveness; The together time inconvenience with the diapire involution, especially obvious when the thickness of the paper that consists of bag is thicker; Thickness maximum when bag is superimposed together is in the centre of antetheca, a plurality of bag piles that are superimposed together can be produced together the time topple over phenomenon, therefore inconvenience when depositing paper bag; Because be provided with four fold line and bag closes up and can cause one folding line wherein darker after depositing in the centre of antetheca and rear wall, in the process to can object in the bag, empty bag easily produces bending along this crease line place and topples over phenomenon, makes troubles to can work.
The utility model content
First purpose of the present utility model aims to provide the good square bottom Paper handbag of a kind of diapire flatness, affects the problem of cosmetic look and the market competitiveness owing to the partially folded poor flatness that is caused with the diapire that solves existing Paper handbag.
Second novel purpose of this use is intended to further provide a kind of mode with the diapire doubling to carry out superimposed square bottom Paper handbag, is superimposed together and easily topples over when carrying out pile and the easy bending problem of toppling over when holding up to solve existing Paper handbag.
Above technical problem solves by following technical proposal: a kind of square bottom Paper handbag, comprise bag and the carry hand or the hand-held hole that are arranged on the bag, the developed surface of described bag comprises left wall, rear wall, right wall, antetheca, be connected to the left egative film on the left wall, be connected to the rear egative film on the rear wall, be connected to right egative film and the front egative film that is connected on the antetheca on the right wall, left egative film, rear egative film, right egative film and front egative film are spliced into the diapire of bag, the centre of Zuo Bi and right wall all is provided with the first broken line that extends along the short transverse of bag, it is characterized in that, also comprise left egative film, rear egative film, the otch that right egative film and front egative film separate.The method of diapire being carried out involution is, make first left egative film and right egative film towards the bag internal bend, then make front egative film and rear egative film towards the internal bend of bag and cover left egative film and right egative film on, because the setting of otch, all be in deployed condition so that consist of four egative films of diapire, so the flatness of diapire is good.If end liner is set in diapire, then can stay the slit between front egative film and the rear egative film is that the two width sum can be less than the width of bag.
As preferably, respectively be provided with two the second broken lines that intersect vertically on described Zuo Bi and the right wall, the intersection point of the second broken line is positioned on the first broken line, the crosspoint of the perpendicular rib of bag and the basal edge of bag is positioned on the second broken line, and diapire is provided with along what the bag length direction extended divides diapire equally tri linear for two halves.By make diapire along the tri linear doubling together, Zuo Bi and right wall along the second broken line doubling be in the same place, left and right sides wall realized closing up of bag along the second broken line doubling again with the overlapping part of diapire together afterwards.This design is so that the position of the apparent thickness maximum of the bag that is superimposed together is positioned at front and rear wall bottom, therefore by the interfolded bag, so that the bag pile is to umbilicate together the time, therefore can not produce rollover during pile.Bag is opened when holding up, and bag naturally is in the lower end and opens the large and little shape in upper end of size, and bag can not produce bending topples over.Give and to use and the work of depositing offers convenience.
As preferably, described front egative film and rear egative film the two, the width of one is that half of bag width is following, the width of another one is greater than half of bag width.When bag folded, the solid thickness at the position of corresponding tri linear was little, descended and the power that causes making diapire to open when descending at tri linear place elastic force, and pile bag together can not produce overturning yet.
As preferably, described front egative film and rear egative film the two, the width of one equal the bag width half, the width of another one greater than the bag width half, width be the bag width half backsheet landing width greater than half the outer surface of egative film of bag width on.It is laborsaving when diapire is carried out doubling.
As preferably, described otch is the wide horn mouth of openend.It is convenient and strength-saving when each egative film bending is superimposed together the formation diapire.
As preferably, the blind end of described otch is arc.In the production process, remove the paper scrap that produces when forming otch convenient, convenient when making mould.
The utlity model has following advantage, the diapire flatness is good, appearance looks elegant; Convenient during pile, bag is not easy to produce the bending overturning.
