Detailed description of the invention
The utility model is further illustrated below in conjunction with accompanying drawing.
As shown in Figure 1, the utility model comprises the hermetically-sealed construction of bag and bag, and hermetically-sealed construction wherein comprises separable handheld ring 1, diaphragm seal 2, multiply pressure-sealing zipper 3, slide fastener slippery fellow 4.The top of diaphragm seal is arranged can the bracelet of folding, and the below of diaphragm seal arranges pressure-sealing zipper, and bracelet, diaphragm seal and pressure-sealing zipper all seal with bag, and in diaphragm seal or pressure-sealing zipper, at least one is for keeping the sealing of bag.Sealing structure can be applicable to multiple bag, comprises bag with square bottom, bellows pocket and three edge sealing bags, can respectively attend Fig. 2 a, Fig. 2 b, Fig. 3, Fig. 4 a, Fig. 4 b, Fig. 5, Fig. 6 a, Fig. 6 b and Fig. 7.
As shown in Figure 8 and Figure 11, diaphragm seal 2 is not separated, and this kind of pouch-type structure can utilize sub-thread slide fastener and traditional Typical zipper, does not have lower seal slide fastener stock 6,7, also can with the slide fastener easily tearing 8 places below multiply pressure-sealing zipper and separate.
As shown in Figure 9, pressure-sealing zipper 3, diaphragm seal 2, separable handheld ring 1 carry out heat-sealing with bag 9,10 successively and weld, when heat-sealing welding 11(is shown in Figure 14) be greater than B according to size A, A is less than C, D be less than C carry out heat-sealing welding time, when filling object or carrying, see Figure 15, object first impacts bag 9,10, impact lower seal slide fastener stock 6,7 again, impact upper pressure-sealing zipper stock 5 again, then impact diaphragm seal 2, its easy-torn line 8 place can not be opened.
As shown in Figure 10, when the object of splendid attire is not very heavy, can by diaphragm seal 2 separately, respectively with bag 9, 10 heat-sealing welding, B is greater than according to A, A is less than C, D be less than C carry out heat-sealing welding time, when filling object or carrying, see Figure 15, object first impacts bag 9, 10, impact lower seal slide fastener stock 6 again, 7, if (when desired strength is not high, lower seal stock 7 can be removed, as long as lower seal stock 6), impact upper pressure-sealing zipper stock 5 again, utilize buffering several times that its easy-torn line 8 place can not be opened, this kind of pouch-type structure easy-torn line 8 place before not arriving in customer's hand cannot open, in case the object of splendid attire runs off,
As shown in Figure 12, Figure 13 a and Figure 13 b, the pressure-sealing zipper in the present embodiment has three strands, is respectively pressure-sealing zipper stock 5, lower seal slide fastener stock 6,7.Pressure-sealing zipper lower end closed, closes place with easy-torn line 8.
If also want to increase the Keying strength between multiply pressure-sealing zipper stock and stock, a heat-sealing welding 12 can be increased again and see Figure 16, Figure 17, first heat-sealing place of pressure-sealing zipper and bag is between upper pressure-sealing zipper stock 5, lower seal slide fastener stock 6, this place and bag bilateral seal, second heat-sealing place of pressure-sealing zipper and bag near easy-torn line, this place and the one-sided heat-sealing of bag.Figure 18 is seen when filling object or carrying, multiply pressure-sealing zipper 3 is stressed along F, G direction, so just increase the Keying strength between multiply pressure-sealing zipper stock and stock greatly, no matter whether diaphragm seal 2 separately seals welding, and multiply pressure-sealing zipper all can not be opened before not reaching in customer's hand.
To sum up, the utility model a kind ofly utilizes a kind of plastic bag encrypted film above multiply sealed explosion-proof slide fastener and add separable handheld ring simultaneously, one, portable part is not cut, foxy 4 are pulled gently with regard to object in desirable output as long as cut off by diaphragm seal 2, again also facilitate during carrying, also can repeated usage, as shopping bag, other article of splendid attire etc., two, if gently pull slippery fellow, just sack can be opened or closed, easy to use, three, above multiply pressure-sealing zipper, add diaphragm seal make its sack airtight, turn increase the intensity at handheld ring place simultaneously.
