In these embodiments, it is at least partly inclined to be respectively relative to antelabium 328A, 328B and 328C by antelabium 326A, 326B and 326C It moves.As shown in Figure 10 B and Figure 10 C, due to the offset between antelabium 326B and 326C and antelabium 328B and 328C, in bag 300B and Multiple protrusions are formed in 300C.When opening opening, multiple protrusions 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 first closure member 407 Antelabium 426 from 414 extended distance H1 of interlocking component, the antelabium 428 of the second closure member is from 418 extended distance H2 of interlocking component. 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 to interlocking structure The distance of part 414 and 418 is more farther than the distance of the edge 412 to the interlocking component 414 and 418 that are formed by the first closure member.

In order to help to distinguish the first antelabium 426 and the second antelabium 428, paint in antelabium 426 and 428.In fact, when the When one side 102 or second side 104 observe bag 400, the first antelabium 426 region Chong Die with the second antelabium 428 is than the second lip Edge 428 and the nonoverlapping region of the first antelabium 426 show eye-catching dark color or eye-catching dark shade.Therefore, user can To be easy the first antelabium 426 of difference and the second antelabium 428, and user is when opening interlocking component 414,416,418 and 420 More easily where determination catches bag 400.

It is readily apparent that from discussion herein, refers to that " dark color " and " dark shade " has different meanings.CIELAB color is empty Between be general technology for quantifying color and coloration.In the color space, L* represents the brightness or depth of color, and a* Color opposition dimension (color-opponent dimensions) is represented with b*, the CIE XYZ color based on non-linear compression is empty Between coordinate.It can be easy to determine L*, a* and b* value of the color of specific sample by using such as spectrophotometer.Such as this paper institute With when considering two color samples, dark sample is the sample that a* and b* value indicates color more deeper than other samples, example Such as, indicate that a* the and b* value of blue is deeper than a* the and b* value for indicating yellow.On the other hand, the dark shade of color indicates there is base This identical a* and b* value but two samples for being different L* value, the sample with higher L* value is light degree.With regard to this point For, it should be noted that term " color " used herein includes black, white and grayness.It should also be noted that such as The plastics preservation bag of substantially transparent discussed above and as known in the art is considered with certain " color ".When When referenced herein first and second color or coloration, the first color and one of the second color or coloration can be with the residues of bag Part is identical, the part of the substantially transparent including bag.

It as a result is exactly that the first antelabium 426 described herein and the second antelabium 428 may be implemented by using different color Visual effect, wherein the a* and/or b* value of antelabium 426 and 428 is different.Qualitatively, the first antelabium 426 can show green Color, and the second antelabium 428 can show red.In such an embodiment, the L* value of two antelabium 426 and 426 can be identical, Or L* value can be different.In other embodiments, the first antelabium 426 and the second antelabium 428 can be set into essentially identical Color, that is, there is about the same a* and b* value, but there is different L* values.In this case, 426 He of the first antelabium Second antelabium 428 has different colorations.Again and in other embodiments, the first antelabium 426 and the second antelabium 428 are formed as phase Same color and identical coloration.Furthermore when the bag from first side 402 or second side 404, due to the first antelabium 426 with the second antelabium 428 a part it is Chong Die, overlapping region show naturally than with nonoverlapping second lip of the first antelabium 426 The deeper coloration of the coloration of the part of edge 428.Such as this effect can be obtained by using the antelabium 426 and 428 of bigger thickness Fruit.Again and in other embodiments, the first antelabium 426 and the second antelabium 428 can be formed by different colors, thus this exists The color different from the non-overlap part of the second antelabium 428 is provided in the lap of antelabium 426 and 428, for example, the first antelabium 426 be yellow, and the second antelabium 428 is blue, so that when observing bag towards first side 402 or second side 404, Green is generated in first antelabium 426 region Chong Die with the second antelabium 428.

In a particular embodiment, the difference of the L* value of two antelabium 426 and 428 is about 30.For example, dark first antelabium 426 L* is about 50 to about 70, and more particularly, L* value is about 55 to 65, and even more specifically, L* value be about 55 to About 60.The L* value of light second antelabium 428 is about 60 to about 80, and more particularly, L* value is about 65 to about 75, and even more In particular, L* value is about 70 to about 75.By all these configurations, the first antelabium 426 shows more basic than the second antelabium 428 It is deeper.Therefore, user can be easy two antelabium 426 and 428 of difference when opening interlocking component 414,416,418 and 420, This then makes user be easier where determination catches bag 400.

By using various technologies color can be formed in antelabium 426 and 428.For example, in the closure for forming bag Before the extrusion operation of part 407 and 409, the colorant of liquid or solid form can be mixed with resin.As similar example, lead to Color can be introduced by crossing addition color resin pellet or color of liquid in pellet stream, and color is forming the film of bag and/or closing It will be evenly distributed in entire plastics during the extrusion process of component 407 and 409.In such configuration, such as by On the closure member 407 and 409 of formation squeeze out color layer can by be entirely extruded into the individual extruder that process is added come Introduce colorant.As another example, color can be coated by the coating on closure member 407 and 409 or printing.This field It will be recognized that the other technologies of wide scope can be used to form color or color in the antelabium 426 and 428 of bag 400 Degree.

Although bag 400 shown in Figure 11 is formed with more dark than long second antelabium 428 color or more dark shade short by the One antelabium 426, but in other embodiments, opposite coloring can be in turn.That is, the first short antelabium 426 can be with With the color more shallow than long antelabium 428 or more shallow coloration.In these embodiments, by only with the first antelabium Color pair can further be emphasized by providing deeper color or deeper coloration in the part of 426 nonoverlapping second antelabium 428 Degree of ratio.In addition, although the entire distance H1 and H2 between interlocking component 414 and 418 and edge 412 and 413 is equipped in Figure 11 institute The color in embodiment shown, but in other embodiments, color does not need to extend entirely distance H1 and H2.On the contrary, color It can extend in a part of the distance H1 and H2 of antelabium 426 and 428.

In other embodiments, color is not the solid slug on antelabium 426 and 428.For example scheme on the contrary, color can be formed Case or shape, pattern and shape are continuously or discontinuously.The example of these patterns and shape includes heart-shaped, flower, tree etc..Along these Line, the coloring of antelabium 426 or antelabium 428 may include multicolour.At this, as described above, the first antelabium 426 and the second lip One of the color of edge 428 or coloration can be identical as the other parts of bag.Therefore, in embodiment, the color of the first antelabium 426 It is identical as the color of side 402 of substantially transparent, and antelabium 428 is formed with two different colors.Those skilled in the art The coloring option of the wide scope of the antelabium 426 and 428 of bag 400 will be recognized.

Interlocking component 414,416,418 and 420 can also colour, and as such, be equipped with antelabium 426 and 428 it is identical or Different colors.Due to coloring, can be easy to differentiate interlocking component 414,416,418 and 420, therefore keep user more easily close Seal simultaneously opened pocket.Therefore, by provide have coloring antelabium 426 and 428 bag 400 and coloring interlocking component 414, 416,418 and 420, user can be easy to distinguish for sealing and the part of opened pocket 400.

Figure 12 shows the bag 500 of still another embodiment according to the present invention.Bag 500 is configured as and above-mentioned bag 100 It is similar, the difference is that antelabium 526 and 528 is colored.First antelabium 526 have than the deeper color of the second antelabium 528 or Deeper coloration.Therefore, user can be easy to distinguish two antelabium 526 and 528.Further, since the first antelabium 526 and second Antelabium 528 is overlapped in the region of the underface of recess 530, so when observing bag towards first side 502 or second side 504 It can see even deeper part 532 when 500.This is provided to user catches in the area of the bag 500 adjacent with recess 530 The visual cues of antelabium 526 and 528 in domain.As described above, can be easiest to open when catching bag 500 near recess 530 Open interlocking component 514,516,518 and 520.

Figure 13 shows bag 600 according to another embodiment of the invention.Bag 600 is configured to Fig. 6 in the same manner With bag 200 shown in Fig. 7, the difference is that the antelabium 626 and 628 of bag 600 is colored.It is included in 626 top of the first antelabium Second antelabium 628 of the part of extension has than the deeper coloration of the first antelabium 626 or color.It is as discussed above other The example of the antelabium of color, user can be easy to distinguish two antelabium 626 and 628.

The coloring of the antelabium 426,428,526,528,626,628 of bag 400,500 and 600 also can permit bag 400,500 Other preservation bags are readily distinguishable from 600.That is, the coloring of antelabium 426,428,526,528,626 and 628 is to specific bag User provide and visually indicate, and this feature can provide the clear of the content of bag or imply instruction.For example, blue Antelabium can serve to indicate that freezer bag, and carmetta antelabium can serve to indicate that freezer bag, and green antelabium can be logical with instruction Use preservation bag.In addition, the antelabium 426,428,526,528,626 and 628 of coloring can permit specific bag in other bag of convexity It is aobvious, for example, carmetta bag is in green bag saliency.Certainly, due to coloring can be made only in antelabium 426,428,526,528, In 626 and 628, so the first side of bag 400,500 and 600 and second side 400,402,500,502,600 and 602 are still It can be made transparent or substantially transparent.Therefore, bag 400,500 and 600 is by antelabium 426,428,526,528,626 and 628 Instruction color is assigned, however still it can easily be seen that the content of bag 400,500 and 600.

In order to further distinguish bag 600 and other bags, bag 600 may include the area for allowing to be easy to write on bag 600 Domain 601, that is, form the region 601 of the label for bag 600.In general, polybag has the label of printing on the surface.In general, This label is for example printed on by elasticity and is coated on the bag of ink.In some embodiments of the invention, the area of bag 600 Domain 601 can be this ink label.

However, in other embodiments, ink forming region 601 is not used, on the contrary, the region is formed as the surface of bag Etching part.Etching area can be formed by using various technologies.It for example, can be by sandblasting come forming region 601. It for another example, can be by ultrasonic wave come forming region 601, wherein the rough surface or embossed surface and bag of vibration amplitude transformer or anvil 600 surface contact.It has been found that executing this etching on the surface for the bag being made of plastics (such as plastics as described above) Technology, which assigns, to be easy to receive the etching area write from standard oil writing brush.The etching technique ratio in region 601 is used to form for shape Ink-printing techniques at region 601 are advantageous, because etching is more cheap than being used to form the ink in region 601.In addition, passing through erosion More environmentally friendly bag 600 can be provided by eliminating using printing ink by carving forming region 601.No matter it should be noted that being used for The technology of forming region 601 is how, can on any surface of bag 600 forming region 601, and in addition, region 601 can be with Be formed as arbitrary shape.

Figure 14 to Figure 16 shows bag 700 according to another embodiment of the invention.Bag 700 be generally configured for Bag as described above is similar, because bag 700 includes the first side 702 and 704 connecting with edge 706,708 and 710.Bag 700 It further include the first closure member 707 and the second closure member 709, and closure member 707 and 709 includes 714,716,718 and of interlocking component 720.First closure member 707 and the second closure member 709 further include the first antelabium 726 and the second antelabium for limiting edge 712 and 713 728.First antelabium 726 and the second antelabium 728 are inclined according to the mode similar with the antelabium 412 and 413 of bag 400 as described above It moves.

In bag 700, the first closure member 707 and the second closure member 709 include texture region 734,736,738 and 740, this A little texture regions are located at adjacent with edge 706 and 708 and adjacent with interlocking component 714,716,718 and 720.Texture region 734,736,738 and 740 dramatically different texture is provided than the other surfaces of bag 700, so that 734,736,738 and of texture region 740 are visually distinguishable from and the region of texture region 734,736,738 and 740 adjacent closure members 707 and 709.However, line Reason region 734 and 736 only extend in a part of length of closure member 707 and 709, and more specifically, with interlocking component 714, the adjacent region in 716,718 and 720 end extends.That is, the first closure member 707 and the second closure member 709 packet Include 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 are formed with the texture-free region adjacent with most of length of interlocking component 714,716,718 and 720.It should be noted that Term " texture-free " used herein refers to the relatively smooth surface being generally found in this field.

Figure 15 and Figure 16 show the details of the texture region 734 of bag 700.Texture region 734 includes being located at interlocking component Section 740, the section 742 between interlocking component 714 and 716 and the area positioned at 716 lower section of interlocking component of 714 tops Section 744.Other texture regions 736,738 and 740 of bag 700 also include relative to interlocking component 714 and 716 or interlocking component 718 and 720 three sections positioned in a similar manner.

It has been found that if user starts seal operation in the end of interlocking component 714,716,718 and 720, such as The zipper form closing structure of the closing structure formed by interlocking component 714,716,718 and 720 is easier to seal, and usually more It adds hermetically sealed.When the process for starting to seal bag, texture region 734,736,738 and 740 provides vision to user and mentions Show to catch closure member 707 and 709 at the position adjacent with the end of interlocking component 714,716,718 and 720.Therefore, make User is easier to correct in the case where texture region 734,736,738 and 740 is provided and guided and bag 700 is fully sealed.

As shown in figure 16, texture region 734 and 736 the interlocking component 716 that can be reciprocal interlocked or unlock, 718, Extend on 720 and 722 partial-length.However, for the ease of interlocking, texture region 734 and 736 is not substantially formed at interlocking structure In part 716,718,720 and 722 itself.That is, the formation of texture region 734,736 have substantially no effect on interlocking component 716, 718, therefore 720 and 722 shape so that interlocking component 716,718,720,722 still can be interlocked effectively, and seals The opening of bag 700.

Texture region 734,736,738 and 740 can be formed by various technology and methods.For example, Ke Yitong It crosses and is embossed with moulding press to closure member 707 and 709 to form texture region 734,736,738 and 740.It for another example, can be by super Sound wave is embossed to form texture region 734,736,738 and 740.It will be understood by those of skill in the art that molding or ultrasonic wave Embossing technology will allow to be formed texture region 734,736,738 and 740 in specific section 740,742 and 744 and will not be It is embossed on interlocking component 714,716,718 and 720, that is, do not crush interlocking component 714,716,718 and 720 or perhaps make it Deform.Certainly, those skilled in the art will recognize that, each of texture region 734,736,738 and 740 can be formed by existing Kind other technologies.For example, can be operated by the micro shaping on closure member 707 and 709 to form texture region 734,736,738 With 740.

It should be pointed out that although the texture region 734,736,738 and 740 of bag 700 be formed in interlocking component 714, 716,718 and 720 tops, between and the section of lower section in, but in other embodiments, texture region 734,736,738 In the only one that these parts can be formed in 740 or two sections.For example, texture region 734,736,738 and 740 can With in the region that is formed only between interlocking component 714,716,718 and 720, but be not formed in interlocking component 714,716, Above or below 718 and 720.On the contrary, texture region 734,736,738 and 740 can be formed in interlocking component 714, 716, in 718 and 720 adjacent only one sections.In addition, again and in other embodiments, texture region 734,736,738 Bag 700 can be formed in 740 side or the one end for being made only in interlocking component 714,716,718 and 720.In embodiment In, for example, texture region 734 can be formed only, and omit other texture regions 736,738 and 740.

Figure 17 and Figure 18 shows bag 800 according to other embodiments of the invention.Bag 800 includes and edge 806,808 With the first side 802 and second side 804 of 810 connections.Bag 800 further includes 803 phase of opening extended to the inside of bag 800 Adjacent the first closure member 807 and the second closure member 809.Closure member 807 and 809 includes interlocking component 814,816,818 and 820. Interlocking component 814,816,818 and 820 is configured to according to mode hermetic bag identical with the interlocking component in above-described embodiment 800 opening.Closure member 807 and 809 also includes the first antelabium 826 and the second antelabium for limiting the edge 812 and 813 of bag 800 828。

First closure member 807 and the second closure member 809 further include multiple pits 852 and 854.As shown in figure 18, it first closes Pit 852 on component 807 is formed as the concave surface 856 in 807 outside of the first closure member, and first inside bag 800 closes The convex surface 858 of 807 side of component.On the other hand, the pit 854 in the second closure member 809 is formed as the outer of the second closure member 809 Concave surface 862 on convex surface 860 on surface, and the surface of the second closure member 809 inside bag 800.

The pit 852 of first closure member 807 is positioned to and is configured to the pit with the relative positioning of the second closure member 809 854 engagements.More specifically, when interlocking component 814,816,818 and 820 is combined with the opening 803 of hermetic bag 800, it is recessed The convex surface 858 in hole 852 can be received in the concave surface 862 of pit 854.As such, pit 807 and 809, which provides, is used for closure member 807 With 809 alignment feature.In addition, the alignment and engagement of pit 807 and 809 are provided to user in user's hermetic bag 800 Notify that user's interlocking component 814,816,818 and 820 is meshingly engaged visually indicate and sense of touch.That is, user exists Visually distinguish pit 852 and 854, and with user move along interlocking component 814,816,818 and 820 it is his or her Finger is felt the convex surface 858 of pit 852 and is engaged with the concave surface 862 of pit 854 with hermetic bag 800.
