The specific embodiment
Below, with reference to accompanying drawing, just the example of plastics bag of the present invention is done an explanation.
Figure 1 shows that the front view of the plastics bag of an example of the present invention.Bag 10 sack 11 and the nozzle-like pouches 21 that formed by plastic sheeting are respectively constituted.Sack 11 is that one piece of material film is folded into two for the bag that the known in the past deposited bag of conduct makes, or two material films are overlapping, and deposited its four limit (part of the A shown in the oblique line of Fig. 1, B, C, D) forms.Again, the following D of portion is deposited behind the fill fluid shape thing in sack 11.
Pouch 21 is by inserting, depositedly forming between the film of the deposited portion C in the top of sack 11.Shown in Fig. 2 A and Fig. 2 B, two hot melts apply two sidepiece E, E and end F deposited (shown in the oblique line) pouch of property plastic sheeting 22,22.One end of pouch 21 is as peristome 23, and peristome 23 inboards are provided with slide fastener 30 in advance.This slide fastener 30 is known, as shown in Figure 3, be by respectively with base portion 31,31 and recess 32, protuberance 33 extrusion moldings, and integrally formed.
Above-mentioned pouch 21 is integral on ground deposited top in the sack 11 deposited portion C, shown in Fig. 4 A and Fig. 4 B, inserts between the plastic sheeting 12,12 of sack 11, and it is deposited in this portion C that the state that goes out with the one distal process is integral ground.Carrying out this when deposited, the inside of the outside of film 22 and film 12 is deposited.And, in order not make film 22 the insides deposited, the inboard face of film 22 has been carried out anti-deposited processing.Described anti-deposited processing can easily be carried out by deposited barrier layer 24,24 (referring to Fig. 2 A and Fig. 2 B) is set.Deposited barrier layer 24,24 can use multiple material, but is preferably, and uses the barrier layer material that is for example formed by the heat-resisting seal China ink of photogravure.
Other examples as anti-deposited processing also can be made of laminated film and double-layered co-extruded film.Its outside makes hot melt and (for example applies the low film of temperature, polyethylene foil), its inboard makes hot melt and (for example applies the high film of temperature, polypropylene film), melt-coating part E, the F of pouch 21 carries out deposited with the deposited high-temperature of inboard film, melt-coating part A, B, C, the D of sack 11 carry out deposited with low temperature.Take this to handle, can obtain the not deposited pouch of its inner face 21.In addition, in that pouch 21 is deposited on sack 11 time, also can insert non-deposited (for example, tagger or plastic flagstone) being used for deposited obstruction between the film 22 of pouch 21.Particularly, the base portion 31 of above-mentioned slide fastener 30 can extend as deposited obstruction film and use.
The bag 10 that above-mentioned formation forms can be as the bag that holds as flow-like things such as powder, colloid shape thing, sticky matter, oils, synthetic paste, Yin Mo, paint.Sack 10 is when manufacturer dispatches from the factory, and its following part D is in not deposited state, more following portion is carried out deposited processing behind fill fluid shape thing.In bag operation 1, make pouch 21 in advance, this pouch is inserted between the material film that constitutes sack 11, additional deposited operation, only this can directly utilize existing bag-making equipment.
During the flow-like thing of user in taking out collecting bag, at first, open the slide fastener 30 of the pouch 21 of the state shown in Fig. 4 A and Fig. 4 B, will point in the insertion pouch 21, pluck the state of carrying pouch 21 the insides, pouch 21 is pulled out to the outside with finger.At this moment, pouch 21 becomes the state that turns up in the inside, pulls out (shown in Fig. 5 A and Fig. 5 B) by slide fastener 30.In addition, also can push sack 11, pouch 21 be extruded to the outside by pressing in the bag.
Secondly, along long and short dash line G shown in Fig. 5 A and Fig. 5 B, the fore-end that cutting pouch 21 is given prominence to forms and takes out with opening 26 (with reference to Fig. 6 A and Fig. 6 B).
Take out the flow-like thing of requirement, then shown in Fig. 7 A and Fig. 7 B,, above-mentioned clip is pressed in the sack 11 closed slide fastener 30 (with reference to Fig. 8 A and Fig. 8 B) with clip 27 latch openings 26.
As above illustratedly, turned up in pouch 21 the insides, pull out as tubular, or squeeze out, when taking out the flow-like thing, the flow-like thing can not contact slide fastener 30.Therefore, the situation that slide fastener 30 is stopped up for the flow-like thing can not take place.
Again, pouch 21 uses the deposited sack of its three fusing of margin, but also can use the sack that one piece of film is folded to form along melt-coating part F shown in Fig. 2 A, perhaps also can use the sack that is folded to form along peristome 23.Using the occasion that forms pouch 21 along peristome 23 folding films, must cut oral area 23 open along long and short dash line G (referring to Fig. 2 A).Again, in the pouch shown in Fig. 2 A 21, also can deposited in advance peristome 23, at this moment, peristome 23 is cut in use.
In addition, the example shown in plastics bag of the present invention is not limited in the scope of spirit of the present invention, can have various changes.
Particularly, the thin bilge construction and the Fabrication procedure of sack and pouch are arbitrarily, and the installation site of pouch also is arbitrarily.Again, slide fastener can use the slide fastener of various structures, can use the higher slide fastener of air-tightness.
