Bag 200 is constructed to make distance H1 be greater than distance H2 and H4, but distance H1 is less than distance H3.Therefore, a part for the antelabium 228 formed by the second closure member 209 extends above the edge 212 formed by the first closure member 207.Therefore easily distinguish the first antelabium 226 and the second antelabium 228, and where provide visual cues to open with regard to interlocking component 214,216,218 and 220 to user with regard to what catch antelabium 226 and 228.In addition, guide user to catch antelabium 226 and 228 in the central area of bag 200, in central area, the second antelabium 228 extends above the first antelabium 226.By catching the antelabium 226 and 228 in central area, user can apply to roll to antelabium, and as described above in connection with Figure 4, this is convenient to separation first closure member 207 and the second closure member 209, and therefore, opens interlocking component 214,216,218 and 220.

Figure 10 A, Figure 10 B and Figure 10 C show bag 300A, 300B and 300C according to another embodiment of the invention.In these embodiments, antelabium 326A, 326B and 326C offsets at least in part relative to antelabium 328A, 328B and 328C respectively.As shown in Figure 10 B and Figure 10 C, due to the skew between antelabium 326B and 326C and antelabium 328B and 328C, in bag 300B and 300C, form multiple projection.When opening opening, multiple projection just can catch the position of bag 300B and 300C to provide even further visual cues.

Figure 11 shows bag 400 according to another embodiment of the invention.In this embodiment, the antelabium 426 of the first closure member 407 is from interlocking component 414 extended distance H1, and the antelabium 428 of the second closure member is from interlocking component 418 extended distance H2.Distance H2 is greater than distance H1 and makes in the whole length of bag 400, and the edge 413 formed by the second closure member 428 is more farther to the distance of interlocking component 414 and 418 than the edge 412 formed by the first closure member to the distance of interlocking component 414 and 418.

In order to help difference first antelabium 426 and the second antelabium 428, paint at antelabium 426 and 428.In fact, when observing bag 400 in the first side 102 or the second side 104, the first antelabium 426 region overlapping with the second antelabium 428 presents eye-catching dark color than the second antelabium 428 and the first nonoverlapping region of antelabium 426, or eye-catching dark shade.Therefore, user easily can distinguish the first antelabium 426 and the second antelabium 428, and where user more easily determines to catch bag 400 when opening interlocking component 414,416,418 and 420.

To understand from discussion herein, mention that " dark color " and " dark shade " has different meanings.CIELAB color space is the current techique for quantizing color and colourity.In this color space, L* represents brightness or the degree of depth of color, and a* and b* represents color opposition dimension (color-opponent dimensions), based on the CIE XYZ color space coordinates of non-linear compression.L*, a* and b* value of the color of specific sample easily can be determined by using such as spectrophotometer.As used herein, when consideration two color samples, dark sample is the sample that a* and b* value represents the color darker than other samples, such as, represents that blue a* and b* value ratio represents that yellow a* and b* value is darker.On the other hand, but the dark shade of color represents two samples with substantially identical a* and b* value different L* values, and the sample with higher L* value is light degree.In this regard, it should be noted that term used herein " color " comprises black, white and grayness.Should also be noted that plastics preservation bag that is as discussed above and substantially transparent as known in the art can be considered to have certain " color ".When mentioning the first and second colors or colourity in this article, the first color can be identical with the remainder of bag with one of the second color or colourity, comprises the part of the substantially transparent of bag.

Result is exactly, and by the visual effect using different color can realize the first antelabium 426 described herein and the second antelabium 428, wherein antelabium 426 is different with a* and/or the b* value of 428.Qualitatively, the first antelabium 426 can present green, and the second antelabium 428 can present redness.In such an embodiment, two antelabium 426 with 426 L* value can be identical, or L* value can be different.In other embodiments, the first antelabium 426 can be arranged to substantially identical color with the second antelabium 428, that is, have approximately identical a* and b* value, but has different L* values.In this case, the first antelabium 426 and the second antelabium 428 have different colourity.More again in other embodiments, the first antelabium 426 and the second antelabium 428 are formed as identical color and identical colourity.Moreover when observing bag from the first side 402 or the second side 404, because the first antelabium 426 is overlapping with a part for the second antelabium 428, overlapping region presents the colourity darker than the colourity of the part with nonoverlapping second antelabium 428 of the first antelabium 426 naturally.Such as by using the antelabium 426 and 428 of more heavy thickness can obtain this effect.More again in other embodiments, the first antelabium 426 and the second antelabium 428 can be formed by different colors, this provides the color different from the non-overlapped part of the second antelabium 428 thus in antelabium 426 with the lap of 428, such as, first antelabium 426 is yellow, and the second antelabium 428 is blue, makes, when observing bag towards the first side 402 or the second side 404, to produce green in the region that the first antelabium 426 is overlapping with the second antelabium 428.

In a particular embodiment, the difference of the L* value of two antelabium 426 and 428 is about 30.Such as, the L* of dark first antelabium 426 is about 50 to about 70, and more particularly, L* value is about 55 to 65, and even more particularly, L* value is about 55 to about 60.The L* value of light color the second antelabium 428 is about 60 to about 80, and more particularly, L* value is about 65 to about 75, and even more particularly, L* value is about 70 to about 75.By all these configurations, the first antelabium 426 presents substantially darker than the second antelabium 428.Therefore, user easily can distinguish two antelabium 426 and 428 when opening interlocking component 414,416,418 and 420, and this makes user where more easily determine to catch bag 400 then.

Color can be formed in antelabium 426 and 428 by using various technology.For example, formed bag closure member 407 and 409 extrude operation before, the colorant of liquid or solid form can with mixed with resin.As similar example, by adding color resin pellet or color of liquid can introduce color in pellet stream, color will be evenly distributed in whole plastics during the formation film of bag and/or the extrusion of closure member 407 and 409.In such configuration, such as can extrude the independent extruder that forming process sets up and introduce colorant by whole by extruding color layer on the closure member 407 and 409 formed.As another example, color can be applied by application on closure member 407 and 409 or printing.Those skilled in the art will recognize that, the other technologies of wide region can be used to form color or colourity with the antelabium 426 and 428 at bag 400.

Although the bag shown in Figure 11 400 is formed with the first short antelabium 426 than the long more dark coloured silk of the second antelabium 428 or more dark shade, in other embodiments, relatively painted can be conversely.That is, the first short antelabium 426 can have the color more shallow than long antelabium 428 or more shallow colourity.In these embodiments, by only with the part of nonoverlapping second antelabium 428 of the first antelabium 426 in provide darker color or darker colourity can emphasize color contrast further.In addition, although the whole distance H1 between interlocking component 414 and 418 and edge 412 and 413 and H2 is provided with color in the embodiment shown in fig. 11, in other embodiments, color does not need to extend whole distance H1 and H2.On the contrary, color can extend in a part of the distance H1 of antelabium 426 and 428 and H2.

In other embodiments, color is not the solid slug on antelabium 426 and 428.On the contrary, color can form such as pattern or shape, pattern and shape continuous or discontinuous.The example of these patterns and shape comprises heart, flower, tree etc.Along these lines, antelabium 426 also or the painted of antelabium 428 can comprise multicolour.At this, as mentioned above, the first antelabium 426 can be identical with other parts of bag with one of the color or colourity of the second antelabium 428.Therefore, in an embodiment, the color of the first antelabium 426 is identical with the color of the side 402 of substantially transparent, and antelabium 428 is formed with two kinds of different colors.Person of skill in the art will appreciate that the painted option of the wide region of the antelabium 426 and 428 of bag 400.

Interlocking component 414,416,418 and 420 also can be painted, and like this, be provided with the color identical or different with antelabium 426 and 428.Due to painted, easily can differentiate interlocking component 414,416,418 and 420, therefore make user more easily seal and opened pocket.Therefore, by providing the bag 400 and painted interlocking component 414,416,418 and 420 with painted antelabium 426 and 428, user can easily distinguish for sealing the part with opened pocket 400.

Figure 12 shows the bag 500 according to another embodiment again of the present invention.Bag 500 is configured to similar to above-mentioned bag 100, and difference is that antelabium 526 and 528 is painted.First antelabium 526 has the color darker than the second antelabium 528 or darker colourity.Therefore, user easily can distinguish two antelabium 526 and 528.In addition, due to overlapping in the first antelabium 526 and the second region of antelabium 528 immediately below recess 530, so even darker part 532 can be seen when observing bag 500 towards the first side 502 or the second side 504.This provides the visual cues of the antelabium 526 and 528 caught in the region of the bag 500 adjacent with recess 530 to user.As mentioned above, when catching bag 500 near recess 530, interlocking component 514,516,518 and 520 can the most easily be opened.

Figure 13 shows bag 600 according to another embodiment of the invention.Bag 600 is constructed to the bag 200 shown in Fig. 6 and Fig. 7 in the same manner, and difference is that the antelabium 626 and 628 of bag 600 is painted.The second antelabium 628 being included in the part extended above the first antelabium 626 has the colourity darker than the first antelabium 626 or color.The example of other painted antelabium as discussed above, user easily can distinguish two antelabium 626 and 628.

The painted bag 400,500 and 600 that also can allow of the antelabium 426,428,526,528,626,628 of bag 400,500 and 600 is easily different from other preservation bags.That is, the painted of antelabium 426,428,526,528,626 and 628 provides vision to indicate to the user of specific bag, and this feature can provide the clear and definite of the content of bag or hint instruction.Such as, blue antelabium may be used for indicating freezer bag, and carmetta antelabium may be used for indicating freezer bag, and green antelabium can with indicating general preservation bag.In addition, painted antelabium 426,428,526,528,626 and 628 can allow specific bag other bag of saliency, and such as, carmetta bag is in green bag saliency.Certainly, the first side of bag 400,500 and 600 and the second side 400,402,500,502,600 and 602 can only be formed in antelabium 426,428,526,528,626 and 628 due to painted, so still can be made transparent or substantially transparent.Therefore, bag 400,500 and 600 gives instruction color by antelabium 426,428,526,528,626 and 628, but still easily can see the content of bag 400,500 and 600.

In order to make bag 600 and other bags distinguish further, bag 600 can comprise the region 601 allowing easily to write on bag 600, that is, form the region 601 of the label being used for bag 600.Usually, plastic bag has the label be printed on surface.Usually, this label is such as printed on by elasticity printing and scribbles on the bag of ink.In some embodiments of the invention, the region 601 of bag 600 can be this ink label.

But in other embodiments, do not use ink forming region 601, on the contrary, this region is formed as the etching part on the surface of bag.Etching area can be formed by using various technology.For example, forming region 601 can be carried out by sandblasting.And for example, forming region 601 can be carried out by super sonic, wherein vibrate ultrasonic transformer or the rough surface of anvil or the surface contact of embossed surface and bag 600.Find, the surface of the bag be made up of plastics (such as plastics as above) performs the imparting of this etching technique and easily receives from calibrating oil writing brush the etching area write.Etching technique for the formation of region 601 is more favourable than the ink-printing techniques for the formation of region 601, because etching is more cheap than the ink for the formation of region 601.In addition, the bag 600 of more environmental protection is provided by eliminating use printing-ink by etching forming region 601.It should be noted that, no matter for the formation of the technology in region 601, can on any surface of bag 600 forming region 601, and in addition, region 601 can be formed as arbitrary shape.

Figure 14 to Figure 16 shows bag 700 according to another embodiment of the invention.Bag 700 is constructed to bag as above similar generally, because bag 700 comprises the first side 702 and 704 be connected with edge 706,708 and 710.Bag 700 also comprises the first closure member 707 and the second closure member 709, and closure member 707 and 709 comprises interlocking component 714,716,718 and 720.First closure member 707 and the second closure member 709 also comprise the first antelabium 726 and the second antelabium 728 limiting edge 712 and 713.First antelabium 726 and the second antelabium 728 offset according to the mode that the antelabium 412 and 413 with bag 400 as above is similar.

In bag 700, the first closure member 707 and the second closure member 709 comprise texture region 734,736,738 and 740, and these texture regions are positioned at adjacent with edge 706 and 708, and with interlocking component 714,716,718 and 720 adjacent.Texture region 734,736,738 and 740 provides significantly different textures than other surfaces of bag 700, make texture region 734,736,738 and 740 be visually different from texture region 734,736, the region of 738 and 740 adjacent closure members 707 and 709.But texture region 734 and 736 only extends in a part of length of closure member 707 and 709, and more specifically, extend in the region adjacent with the end of interlocking component 714,716,718 and 720.That is, first closure member 707 and the second closure member 709 comprise the texture region 734,736,738 and 740 adjacent with the part of interlocking component 714,716,718 and 720, but closure member 707 and 709 is formed adjacent with most of length of interlocking component 714,716,718 and 720 without texture region.It should be noted that term used herein " without texture " refers to the comparatively smooth surface usually found in this area.
