Description of Related Art

The wiping wet tissue that the commercial consumer products that can various forms obtain are arranged much as everyone knows.Perhaps the prevailing form of wiping wet tissue is a folded thin slice that has been packaged in the humidification in the plastic container.The wiping wet tissue can be made by the material of the various suitable polishing solution humidifications of various usefulness.Be typically, the wiping wet tissue is deposited in the container with folding or not folding form.For example, can obtain this wiping wet wipe container, each the wiping wet tissue that wherein is stacked in this container has been positioned to folding, the Z type the is folding or folding folded form of orthogonal type of C type, and this point is well-known to those skilled in the art.In this folded wiping wet tissue, some folding wiping wet tissues also have directly in the above with following wiping wet tissue by interfolded.In the embodiment that replaces, the wiping wet tissue is placed in the container with the form of the continuous wire side of material, and the continuous fiber netting gear of this material has separating the perforation of independently wiping wet tissue, and it can be wrapped on the cylinder.This wiping wet tissue is as baby wipes, hand towel, household cleaning wiping cloth, industrial wiping cloth or the like.

As mentioned above, the traditional packing of holding the wiping wet tissue typically is designed to be positioned on the flat surface as work top.This traditional packing provides plastic container or bucket basically, provides a kind of leak free environment can not become too dried to guarantee them to give the wiping wet tissue.Some traditional packings also are configured to once distribute the structure of a slice wiping wet tissue, and after unpacking, an available hand is finished every wiping wet tissue of distribution.Distribution this one hand, an a slice is special needs, because user or the another hand that carries out the care-giver need to be used as simultaneously other function basically.For example, when giving baby's changing babies' napkin, carry out the care-giver and have the baby in arms with a hand basically and make the baby keep a desirable direction, the another hand will be distributed a slice baby wipes with the cleaning baby simultaneously.

But the opening of so traditional wiping wet wipe container is not to be entirely satisfactory.For example, a lot of traditional containers can not be opened with a hand, even or be designed to an available hand and open, but for all users and be not easy to open with a hand.For such container, the user must with the hands unpack before distribution wiping wet tissue basically.A lot of such containers are difficult to open, because they comprise that one forms just friction sealed lid with container body, just can guarantee that when it is closed the wiping wet tissue can not become too dried.In addition, a lot of traditional containers comprise less relatively, be difficult to a hand-guided cap-opening mechanism.

Another difficulty relevant with traditional wiping wet wipe container is that container cover must be to open fully or close fully basically.The overturning backward owing to the weight of the lid of opening of container possibility, this depends on the weight of the wiping wet tissue that is retained in the container.Therefore, traditional container does not provide a kind of position that partially opens between container cover and container body.Thereby when the amount of wiping wet tissue in the container reduced, just becoming was difficult to get the wiping wet tissue from container with a hand.In some traditional containers, the alignment between container cover and container body is not so good.This not so good alignment has hindered the user that lid is fixed to ability on the body, particularly when must carrying out this operation with a hand.

In the use of the wiping wet tissue of some wiping wet tissues when being used for changing babies' napkin, it is very high to hold the frequency that the container of wiping cloth opens and closes.Open and close container cover continually and cause on connection between lid and the body or fixed part, producing wearing and tearing and stress.After a large amount of circulations that open and close, this connection may begin to lose efficacy, and will cause container cover to be ripped on container body in some cases.The rough surface of the container cover of ripping may tangle skin or fabric, thereby becomes obstacle.In the past, the exterior contour of some conventional container is the right angle that has the Roughen Edges that may tangle skin or fabric.For example, there is the right angle at the point of connection place through being everlasting between container cover and the container body.

In the shipment of container and storing, container often is on the top that vertically is stacked on another.Can realize piling up on the supporting plate or in shipment/reservoir vessel.Container causes having significant masterpiece to be used on the vessel top on the top that vertically is stacked on another.If container does not have enough compressive strengths, lid or body just may be outwardly-bent or bending and being out of shape.Some traditional containers are not designed to stand the size of the power that will stand in routine shipment and storage process.

Summary of the invention

According to above-mentioned difficulties and problem, a kind of new wiping wet wipe container is proposed, it has improved opens and ways of distribution, and the alignment between lid and the body has been improved in the position that can keep the part to open, and has improved pulling force resistance and has improved compressive strength.To illustrate objects and advantages of the present invention in the following description and make it apparent, also will understand objects and advantages of the present invention according to application of the present invention.Particularly in its specification sheets of writing and claims and accompanying drawing, pointed out the additional advantage that realizes and obtain by container of the present invention.

On the one hand, the present invention relates to comprise the wiping wet wipe container of a container cover and a container body.Container cover is connected on the container body.Container cover and container body can be monomer spares or can be part separately.Connection between container cover and the container body can be super sonic connection, interlocking hinge spare or other connection mode as known in the art.Container cover has top, antetheca, rear wall and a pair of relative sidewall.These walls extend downwards with rectangular shape basically from the top of container cover.These walls also can extend downwards with trapezoidal shape basically.Container body has bottom, antetheca, rear wall and a pair of relative sidewall.These walls extend upward inside to provide one to hold the wiping wet tissue with rectangular shape basically from the bottom of container body.These walls also can extend upward with trapezoidal shape basically.

A guide ridges of extending is downwards arranged at the top of container cover.The rear wall of container cover limits an about length identical with the total length of container.Guide ridges is arranged essentially parallel to the rear wall of container cover, and guide ridges is positioned near the position of rear wall or near rear wall.The length of guide ridges is less than the length of rear wall.For example, guide ridges length and the rear wall length ratio of representing container length basically can be expected but not be uniquely in the about scope of 40%-about 90%.And guide ridges can be extended the distance that is approximately the 0.25-0.75 inch downwards.Guide ridges also can have the thickness of about 0.0625-0.25 inch.The rear wall of container body has the top that the limit is accepted in a qualification.This accepts the guide ridges that the limit is configured for admitting container cover basically.For example, this to accept the limit can be arc.When container cover when open position turns to off position, this is accepted the limit and admits guide ridges gradually.In others, guide ridges is convenient to the singlehanded container that opens and closes.In addition, guide ridges has been improved the alignment between container cover and the container body.Guide ridges also allows container cover to be in the position that partially opens.When container cover was in the position that partially opens, even have only a small amount of wiping wet tissue to be retained in the container, container was still stablized and can overturning.In the position that partially opens, container cover is about 1.5-3.0 inch place above container body.The position that partially opens allows a people only just can enter container with a hand and takes out the wiping wet tissue.

Container cover can be made by poly-mer, copolymer or both compounds.For example, container cover can be made by the s-B-S copolymer basically.Container cover can be transparent or semi-translucent, on the part, so that determine to be retained in the quantity of the wiping cloth in the container.Equally, container body can be made by poly-mer, copolymer or both compounds.For example, container body can be made by polystyrene basically.Container body can be to be made by opaque, semi-translucent or material transparent.Dyestuff, pigment and colorant can be added to or the material of container cover or container body in.Wiping wet wipe container of the present invention can not be used for second purpose valuably when they are not used further to hold the wiping wet tissue.For example, this container can be used for storing nicknack, workmanship and other household supplies.When container cover and container body are semi-translucents or when transparent, can open lid and just can find out in the container what is arranged.

Detailed description of the present invention

The present invention is introduced into and is used to solve about the use of traditional container that is used for the wiping wet tissue and the problem of durability.As being schematically shown among Fig. 1-8, the invention provides a kind of wiping wet wipe container 20, constructing this container is to be used for using and distributing the wiping wet tissue with convenient and failure-free mode the individual.Wiping wet wipe container 20 comprises container body 22 and container cover 24, and container cover 24 is connected to or is added on the container body 22.Container body 22 and container cover 24 can be made as monomer spare or they can be parts separately.By known various machineries and method chemistry in the prior art, container cover 24 is connected on the container body 22, includes but not limited to articulation piece, interlocking part, glue or other connects material or the super sonic bonded assembly uses.

The wiping wet tissue can be positioned in the container 20 in any way, can conveniently and reliably provide a wet tissue with this mode at every turn when distributing, and guarantee that the wiping wet tissue can not become too dried.For example, the wiping wet tissue can be positioned in the container 20, becomes a plurality of individual sheets that are placed in the stacked structure, and is folded independent folding or be not independent folding wiping wet tissue to form one.The wiping wet tissue can be to be folded into independently wiping wet tissue c type structure or z type structure, and this point is well-known to those skilled in the art, then on top that is stacked in another to form a folded wiping wet tissue.Perhaps, if the wiping wet tissue is placed in the container 20 with stacked structure, independently wiping wet tissue can be folding mutually, so that the leading end and the trailing end edge of the continuous wiping wet tissue in the stacked structure overlap each other.In this structure, when guiding wiping wet tissue was taken away by the user, because the effect at the trailing end edge of guiding wiping wet tissue, the leading end edge of towing wiping wet tissue was released from lamination.By those of ordinary skill in the art's known method, the wiping wet tissue can be folding mutually, thereby is convenient to such distribution.

Perhaps, the wiping wet tissue can be positioned in the container 20, becomes the continuous fiber net of interconnected wiping wet tissue folding as the stacked structure of concertina.Independently wiping wet tissue is joined together along easy broken string such as perforation line, to guarantee that towing wiping wet tissue is in the position that allows the user catch after being removed of guiding wiping wet tissue.For example, the wiping wet tissue can be made of the continuous fiber net materials, and this material has a series of easy broken strings on the width of perforating fiber net.Web material between continuous easy broken string partly forms independently wiping wet tissue separately.Can be with those of ordinary skill in the art's known method as forming easy broken string in web material middle punch, the mode that forms indentation or otch is set.For example, web material in web material, forms easily broken string or perforation by being passed between die-cut roller and anvil roller.After easily broken string had been incorporated in the web material, this fleece can be settled so that put into the inside 38 of container 20 to pile up form then.

Wiping wet wipe container 20 of the present invention can comprise the independently wiping wet tissue of any right quantity that depends on required packing and application target.For example, container 20 can be constructed to be permeable to hold one and be stacked to less about 5 wiping wet tissue, and desirable approximately be 16 to 320 independently wiping wet tissues.

Each wiping wet tissue is rectangle basically, and defines a pair of opposed side edge and a pair of relative end margin that is known as guide edge and trailing edge.The guide edge of each wiping wet tissue is located substantially in the container 20 position that will be caught by the user so that the user takes out this wiping wet tissue from container 20.Each wiping wet tissue defines not folding width and not folded length.The wiping wet tissue can have any suitable not folding width and folded length not.For example, the wiping wet tissue can have and is approximately 2.0-80.0 centimetre not folded length, and desirable approximately be 10.0-25.0 centimetre, be approximately 2.0-80.0 centimetre not folding width, and desirable approximately be 10.0-45.0 centimetre.

The material that is suitable for wiping wet tissue of the present invention to those skilled in the art is well-known.The wiping wet tissue can be made by any material that is suitable for use as wet wipes, comprises melt-blown, shaping altogether, air lay, sticking comb section bar material, waterpower winding-type material etc., and can comprise synthetic or natural fiber material or its complex.The basic weight of wiping wet tissue is the about 25-120 of an every sq m gram, and desirable approximately be that the about 40-90 of every sq m restrains.

One concrete aspect, the wiping wet tissue can comprise common shaping (coform) substrate of polymer microfibers and basic weight be the about 60-80 gram of every sq m, desirable approximately be the cellulose fibre of about 75 grams of every sq m.The manufacturing of this substrate that is shaped altogether here is incorporated herein by reference basically as described in the people's such as Anderson that published on July 11st, 1978 the U.S. Patent No. 4100324.Basically this substrate that is shaped altogether comprises the gas shaping matrix of the polymerization melt-blown microfiber of thermoplastic plastic, for example Polypropylene Tiny Fiber and cellulose fibre, for example wood pulp cellulose.The relative percentage of polymeric microfibers and cellulose fibre can in very large range change according to the feature of required wiping wet tissue in the substrate that is shaped altogether.For example, based on the dry weight of the common shaping substrate that is used to provide the wiping wet tissue, the polymeric microfibers that the substrate that is shaped altogether comprises can account for about 20 weight %, desirable is about 20-60 weight %, and that better is about 30-40 weight %.

It can be a kind of liquid of any solution that the wiping wet tissue of another aspect of the present invention comprises, and this liquid can be absorbed by this wiping wet tissue.This liquid that is included in the wiping wet tissue can comprise any suitable composition that required wiping characteristic can be provided.For example, this composition can comprise water, emollient, inhibiter, anti fouling composition, chelaization agent, pH value buffering agent or its composite.This liquid also can comprise lotion, finish and/or medicament.

The amount that is included in the liquid in each wiping wet tissue according to the material type, the kind of liquid that is used that are used to form the wiping wet tissue, be used for storing the Container Type of this folded wiping wet tissue and the application target of required wiping wet tissue changes.Based on the dry weight of the wiping wet tissue that is used for improving wiping, the liquid that comprises of each wiping wet tissue can account for about 150-600 weight % basically, desirable is about 250-450 weight %.One concrete aspect in, wherein wiping wet tissue is made by being total to shaped material, dry weight based on the wiping wet tissue, this material comprises the polymeric microfibers of about 30-40 weight %, dry weight based on the wiping wet tissue, the liquid that is included in the wiping wet tissue accounts for about 300-400 weight %, and that desirable is about 330 weight %.If the amount of liquid is less than the above-mentioned scope of pointing out, then wiping wet tissue can be too dried and can be fully utilized.If the amount of liquid is greater than the above-mentioned scope of pointing out, then wiping wet tissue can be satiated and be drenched, thereby liquid may collect in the bottom of container.

Shown in Fig. 1-8, wiping wet wipe container 20 comprises a container body 22, and it defines the bottom 28 that links to each other with 36 with antetheca 30, rear wall 32, a pair of relative sidewall 34.Antetheca, rear wall and sidewall 28 extend upward to form a rectangular vessel body 22 from the bottom in vertical mode basically.Container body 22 also can be trapezoidal.The bottom of container body 22, antetheca, rear wall and two sidewalls limit a unlimited inside 38 basically to hold the wiping wet tissue.This wiping wet wipe container 20 also comprises a container cover 24, and it limits a top 40 that links to each other with 48 with antetheca 42, rear wall 44, a pair of relative sidewall 46.Antetheca, rear wall and two sidewalls 40 extend downwards to form a rectangular vessel lid 24 from the top in vertical mode basically.

The container body 22 of container 20 and container cover 24 can be formed by various materials not too expensive and can receiving fluids.Suitable material comprises polypropylene, polyethylene and polystyrene etc. or its composite.For example, container body 22 can be made by the polystyrene material of thick about 0.010-0.080 inch.Container cover 24 can be made by the copolymer of the polystyrene material of s-B-S and thick about 0.005-0.060 inch.

Each wall 30,32,34 of container body 22 and 36 can form with bottom 28 integral body, comprises that perhaps the separation member that is connected or is installed into bottom 28 is to form container body 22.Equally, each wall 42,44,46 and 48 of container cover 24 also can form with top 40 integral body, comprises that perhaps the separation member that is connected or is installed into top 40 is to form container cover 24.It is desirable to, be curved to form more good-looking container 20 aesthetically at body 22 and connecting portion or the bight covered between 24 each wall, top 40 and the bottom 28.

Can be the known different component that forms container 20 as thermoforming or injection-molded conventional art with those of ordinary skill to ability.For container of the present invention, container body 22 and container cover 24 are shaped as single unit system in certain embodiments.In some instances, can adopt injection-molded technology to form single unit system.When container body 22 and container cover 24 are separation member, be typically the thermoforming technology of using.

In one embodiment of the invention, container 20 comprises container body as described herein 22 and container cover 24.Except top 40, antetheca 42, rear wall 44, sidewall 46 and 48, container cover 24 also can comprise a guide ridges 50 of extending downwards.Guide ridges 50 is arranged essentially parallel to the rear wall 44 of container cover 24.Guide ridges 50 is located substantially near the position of rear wall 44 or near rear wall 44.The rear wall 32 of container body 22 has top 52.This top 52 is topmosts of rear wall 32, thereby the part of rear wall 32 the most closely contacts with container cover 24 formation.Extend along the total length of rear wall 32 on this top 52.This top 52 limits one and accepts limit 54.This is accepted limit 54 and is configured for the guide ridges 50 of admitting container cover 24.For example, this accept limit 54 can be arc to admit guide ridges 50.When container cover 24 was closed on container body 22, this was accepted limit 54 and admits guide ridges 50.

In one embodiment of the invention, when container cover 24 downwards when off position rotates, this guide ridges 50 is accepted limit 54 with this and is contacted, and this is accepted limit 54 and forces guide ridges 50 and be positioned at the front that this accepts limit 54 downwards.Therefore, when container cover 24 was closed on container body 22, this guide ridges 50 was separated so that be in the front that this accepts limit 54 fully with rear wall 44.Because this guide ridges 50 is extended downwards from the top 40 of container cover 24, this guide ridges 50 can be described as to be had and highly relative " degree of depth ".The degree of depth of this guide ridges 50 is enough to accept under the nadir on limit 54 or the bottom at this extends.This guide ridges 50 has improved the simplicity that container cover 24 is closed with this combination of accepting limit 54 on container body 22.And the combination that guide ridges 50/ is accepted limit 54 helps the alignment of container cover 24 on container body 22, so that firm off position to be provided.Because container cover 24 and container body 22 are suitably alignd, container cover 24 is covering container body 22 fully, and container cover 24 will the possibility of " ejection " reduce on container body 22.If container cover 24 is partially or completely separated with container body 22, the moisture of the wiping examination wet tissue product that then stores in container 20 will be lost.Therefore, wiping wet tissue product will lose the ability that realizes that it wants the function that reaches.

Be in the relation that partially opens by making between container cover 24 and the container body 22, this guide ridges 50 also helps the one hand of container 20 to use with this combination of accepting limit 54.Be typically the position that existing container can only keep or open fully or cut out fully.When having only a small amount of wiping wet tissue to be retained in the container 20, and container cover 24 is when open position, and entire container 20 can be because the weight of container cover 24 have balance and overturning backward.The overturning of container 20 makes one hand catch the wiping wet tissue comparison difficulty that becomes.When guide ridges 50 rests in when accepting on the limit 54, can realize the position that partially opens.Use container of the present invention, can overcome and the relevant difficulty of container 20 overturnings, and the still available hand of user is taken the wiping wet tissue away from container 20.Even when not having the wiping wet tissue to be retained in the inside 38 of container 20, container 20 of the present invention can overturning yet.Basically when container cover 24 was in a partly opened position, it was apart from container body 22 about 1.5-3.0 inches.At least owing to these reasons, container of the present invention is easier to singlehanded the use, and when a small amount of wiping wet tissue was retained in the container 20, they were more stable.

Guide ridges 50 with accept limit 54 multiple structure can be arranged.Be typically, shape or the profile of accepting limit 54 will local at least profile or the shapes that is complementary to the guide ridges of facing 50 downwards.Though accept limit 54 thickness is arranged, this accepts limit 54 is bidimensional basically.Accepting limit 54 can extend along the total length on the top 52 of rear wall 32, and perhaps only 52 partial-length extends along top.Guide ridges 50 has length 51 (as shown in Figure 3), the degree of depth 55 (as shown in Figure 7) and thickness 53 (as shown in Figure 3).Basically the length 51 of guide ridges 50 is less than the length of rear wall 44.It is desirable to, the length 51 that guide ridges 50 has a guide ridges 50 and the length ratio of rear wall 44 are approximately the length of 40%-90%.In most of embodiment, the scope of the degree of depth 55 of guide ridges 50 is greatly about the 0.25-0.75 inch.The scope of the thickness 53 of guide ridges 50 approximately can be at the 0.0625-0.25 inch.In the section drawing of schematic container 20 shown in Figure 7, when container cover 24 is closed, are appreciiables against the position of the guide ridges 50 of the rear wall 32 of container body 22.

As described herein, container of the present invention can be made by the material beyond the composite of poly-mer, copolymer or poly-mer and copolymer.Can add other composition to give or whole container 20 or independent container body 22 provide different functional characteristics with container cover 24.In an example, container body 22 is formed by the polystyrene that about 98% height compresses, as can be from Dow Chemical of Midland, and the Dow SYRON  484 that the company of M1 has bought.The residual components of container body 22 can be a kind of improvement composition that compresses, as the STEREON  that can buy from Firestone Company company.In an example of container cover 24 of the present invention, container cover 24 can be made by about 70% s-B-S copolymer, as the FINAPRENE that can buy from Fina Oil and Chemical company ^TM, Finaclear 520 thermoplastic elastomers.Container cover 24 can comprise the polystyrene of about 20% general applications, as the FINA  polystyrene 524B that can buy from Fina Oil and Chemical company.Container cover 24 also can comprise the polystyrene that about 10% height compresses, as Dow SYRON  484.If desired, container cover 24 can comprise that content accounts for the colorant of the 0.08%-1.2% of weight greatly.Those colorants that are fit to it is well known to those having skill in the art that.

In the container cover 24 of container of the present invention and the container body 22 one or another can be transparent, semi-translucents or opaque.In container cover 24 or the container body 22 arbitrarily one be transparent or semi-translucent has been brought some advantage.For example, when container cover 24 is transparent, the user of container 20 can determine to be retained in the quantity of the wiping wet tissue in the container 20 at an easy rate.That is, the user's container cover 24 that can open container just can determine to be retained in the quantity of the wiping wet tissue in the container 20.This is a usefulness in a measure, because sell the wiping wet tissue product that some do not have container in replenishing packing.The customer can buy the wiping wet tissue in the container as described herein 20 discontinuously, buys the wiping wet tissue of replenishing in the packing but also can replenish.The customer can fill up container 20 again with the part of the additional wiping examination wet tissue of being bought of packing.When container cover 24 and container body 22 all were semi-translucent, container 20 of the present invention can expect to be used for second purposes.For example, when the user did not re-use container 20 and holds the wiping wet tissue, the user can store nicknack, workmanship and other household supplies with container 20.If container 20 is semi-translucents, people can cover 24 or needn't settle again under the situation of the top that is placed on container 20 or articles for use on every side and just can find out the thing of being adorned in the container 20 not opening.

In container cover 24 or container body 22 one or another are colored, can also obtain the advantage on aesthetic and the function.For example, can distinguish packing of dissimilar wiping wet tissues with the container of different colours.Equally, when container cover 24 or container body 22 all have pattern to print thereon, also can obtain the advantage on aesthetic and the function.Except aesthetic benefit, pattern can also be used to distinguishing dissimilar wiping wet tissue products.

As describing here, container cover 24 and container body 22 can be shaped as monomer spare, or are shaped as separation member.For the container that is configured as two separation members of the present invention, can connect container cover 24 or install on the container body 22 with the known various technology of the those of ordinary skill of ability.In certain embodiments, container cover 24 can link to each other at their rear wall place with container body 22.By using glue, lining cement or other coupling agent; Pass through heat seal; Connect by super sonic; Or by using physical connector such as pin or interlocking part, the rear wall 44 of container cover 24 can be connected on the rear wall 32 of container body 22.

In another embodiment of the present invention, container 20 comprises container body 22 and the container cover 24 of separating, and this container cover 24 is connected on this container body 22.Schematically show as Fig. 6-8, the rear wall 44 of container cover 24 has an outward extending flange 60.This outward extending flange 60 is bidimensional basically, and this flange has width 61 and length 63.Extend on this outward extending flange 60 plane away from rear wall 44 on vertical substantially direction.Flange 60 comprises three normal areas: the zone of the most close rear wall 44, that is, and near adjacent region 66; Articulated section 64; With bonding pad 62.This bonding pad 62 is positioned at from rear wall place farthest, and articulated section 64 is arranged on the central authorities near adjacent region 66 and bonding pad 62.In three zones of flange 60 or the part each all is linearity configuration basically, and each zone all has independently length, width and thickness.These three zones are parallel to each other basically, and extend on the direction of the rear wall 44 that is basically parallel to container cover 24.The rear wall 32 of container body 22 has top or top 52, and extend away from the partial linear of bottom 28 along rear wall 32 at this top 52.This top 52 has outward extending antelabium 70.This outward extending antelabium 70 is the plane basically, and leaves top 52 and extend on vertical substantially direction.By being connected of flange 60 and outward extending antelabium 70, container cover 24 is connected on the container body 22.More specifically, the bonding pad 62 of flange 60 links to each other with outward extending antelabium 70.Therefore, basically, container cover 24 and container body 22 are connected to each other along their rear wall.Use any technology known to a person of ordinary skill in the art bonding pad 62 and outward extending antelabium 70 can be joined to one another.A kind of suitable technique is that for example super sonic connects.

In one embodiment of the invention, the end edge of flange 60 can be splayed.The end that causes flange 60 of splaying of the end of flange 60 is curved.When the end of flange 60 has curve shape, this end angulation 69, as shown in Figure 8, this angle is away from rear wall 44 and less than 90 degree.In traditional container, the hinged edge between container cover and container body can be vertical with the base plate of container cover or become 90 degree.Curvilinear figure and angle make container 20 have several advantages less than the design of 90 degree.The curvature of the end edge of flange 60 provides the container 20 friendly more with the user, is because this flange 60 unlikely hooks fabric or skin.When the edge of flange 60 when a curve is tapered, have maximum length near adjacent region 66, and bonding pad 62 has minimum length.Yet the length of flange 60 can not surpass the length of rear wall 44 basically, and whether trizonal length can be with splaying and how to splay and change.For example, in a specific embodiment, the length of articulated section 64 approximately can be the 60%-85% of rear wall 44 length.The length of bonding pad 62 approximately can be the 50%-75% of rear wall 44 length.

In another embodiment of the present invention, there are two ends articulated section 64, and each end of articulated section 64 all comprises end 68.Articulated section 64 has one first thickness, and end 68 has second thickness.Second thickness of end 68 is basically greater than first thickness of articulated section 64.For example, first thickness of articulated section 64 approximately can be the 0.005-0.015 inch.Second thickness of end 68 approximately can be greater than the 20%-100% of first thickness.In a similar embodiment, the gross thickness of this outward extending flange 60 is along the change width of flange 60.The same with the length of the flange 60 of splaying described herein, the thickness of flange 60 can gradually change crossing on three zones of flange 60.The gradually changing or being tapered of flange 60 thickness shown in Figure 8.
