Detailed Description Of The Invention
Referring to Fig. 1, angle brace limit bag 10 has a flat substantially end 12, thereby can be erected at horizontal support surface (not shown), for example, and common bag in the coffee package.The main body 14 of bag is made by plastic film, and for example polyethylene (at the inside face of bag, promoting fresh-keeping) and polyester (at the outside face of bag, the raising durability) lamination forms.Lateral end sealing 16 and vertical fin shaped sealing 18 make film form graphic bag shape, have the internal cavities shown in Fig. 3 view.
Referring to Fig. 1, bag 10 has two surface fastener elements once more, can make a bag top remain closed reeling condition to be used for storage with taking apart.Nonreentrant surface hasp 20 sticks on along its upper limb on the back 22 of bag, and the most of area in the bottom of hasp 20 freely stretches out from bag.Hasp 20 preferably by the plastic resin of certain width be suspended to be configured as have a series of integrally formed can with the protruding hasp element of engagement of loops, stretch out from its broad outside face.Can form these hasps by the process that Fisher describes in US Patent 4794028, this patent is incorporated herein by reference document.In this embodiment, its vertical shaping direction is extended along the bag face, hook-shaped hasp element extends along the width of bag.But, can use the protruding hasp element of other shape, perhaps when being used for colluding up when bag last and/or down.Preferably, hasp 20 has resin compatible with the outside face of bag 10, thereby for example, the hasp upper limb can for good and all be attached on the bag by thermal.Other associated methods that is fit to comprises use pressure sensitive adhesives (PSA) or wet quick adhesive agent (MSA), for example resinous coat.
Recessed surface fastener 24 towards the applied on top of bag on the front 26 of bag 10.But hasp 24 has the junc-ring or the fiber that can engage with the hasp element of hasp 20, and for good and all is fixed on bag film and (for example passes through heat seal) along two long limits of bag at least, preferably along the whole back side (for example by heat seal or adhesive agent) of bag.The fiber that is exposed to hasp 24 outside faces can be, for example, and above-mentioned ASPEN material.As shown in the figure, hasp 20 and 24 extends on the whole width of bag 10 substantially.
For closed bag 10, at first with partially folded on ring hasp 24 upper limbs of the top of bag, as shown by arrow A.The foldable bag top is the part under hasp 24 lower edges, as shown by arrow B specifically once more.Then for the third time, only on top, will gang up with the edge joint of button 20 specifically, and the exposure composition surface of hasp 20 and 24 will be bonded with each other (shown in Fig. 2 A) the bag top fold.When the lower edge of hasp 20 is attached on bag face, discharge the bag top of reeling in this position, (promptly the peeling off) that will apply normal direction on surface fastener separates load, because the bag top of reeling is flexible and it tends to open.But because does not paste the lower part of hasp 20, the elasticity at the bag top of reeling is with upwards pulling of hasp 20, around the upper limb bending of its stickup, up to forwarding the bag top of reeling to the outside face points upwards, shown in Fig. 2 B.Have been found that to have this thin, the deformable matrix that colludes, hasp 20 can be pulled up to the direction of offset from perpendicular 10 to 30 degree.And the tendency that the bag top of reeling is tending towards opening produces load between surface fastener, mainly be shearing load (promptly being parallel to its face of joint), this be a kind ofly protrudingly know, with peel off the easier load mode of being born of comparing by surface fastener.Shown in Fig. 2 A and 2B, after decontroling the coiling top, the coiling top is folding bottom almost completely opens, and the hasp 20 of below upwards rotates arrival shearing load direction.It should be understood that the folding times that can find out other for this general bag closing structure, last folding being used at least in part of any this folding times moved closure to the shearing load orientation.For example, Figure 11 A-11C represents different folding times.Folding many more, closed sealing is good more.
Fig. 4 represents to reach above-mentioned distance between the preferred hasp 20 and 24 when folding.The width " W " of ring hasp 24 is about 1/2 inch (12.5mm), and the distance of the upper limb 28 of distance bag equals the fragment " X " that its width deducts about 1/8 inch (3.2mm).Gang up with the button 20 be combined on bag face the position the ring hasp 24 below, the distance between the two is that the width " W " of hasp 24 adds fragment " X ".Consider fold thicknesses, regulate when these fragments are used for reeling at the bag top.Hasp element arrays on the hasp 20, width also are about " W ".
Fig. 5 represents to have the closed bag 20 in volume top, and its function is any number of times during the top can fold several times.The structure of this bag is particularly useful, for example, is applied to the user and along with the minimizing of article in the bag bag is subsided.For example, the bag of dress charcoal lump is so a kind of application.Article one, ring hasp 24 vertically extends in whole bag front 32, and of engaging with it gangs up with button (not shown at this) and extends on the back 34 of bag in a parallel manner.When bag top fold one or many, two opposing face, and each hasp that is loaded with above, being bonded with each other forms knock-down joint.In this embodiment, collude and encircle band and for good and all be combined on bag film, promptly corresponding to the whole length of bag along its whole length.It should be understood that this special construction can not mainly be the advantage of shearing load, but can obtain a lot of other above-mentioned advantages.
Fig. 6 represents to be in the bag 30 that empties with open mode, the bag before for example filling.For the vertical fin-shaped sealing of representing to be covered by loop member, extend previously at bag 18 from angle attractive in appearance, among the figure only with empty outline line representative ring element 24.Loop member 24 can paste on the vertical fin-shaped leak free bag film of both sides with adhesive agent 36, shown in Fig. 7 A, on one side the fin-shaped leak free free edge that perhaps can align, shown in Fig. 7 B.Two kinds of methods have tangible advantage, and the hasp shown in Fig. 7 A can be applied on the bag after forming the fin-shaped sealing, and if desired in addition can finish to be shaped and filling process after use.On the other hand, hasp shown in Fig. 7 B, be direct heat in conjunction with or be welded on bag film, can be applied to before shaping and the filling bag on the bag film of film shape, the hasp band is delivered directly in bag former with continuous length, be applied to each edge and the middle part of bag film in the time of perhaps on being wound up into roller, thereby obtain two preferred embodiments.
Fig. 8 A-8C represents to combine the roll top bag constructions of shearing load and different adjustment ability.Article one, loop member 24 for good and all pastes the front of bag 40, and is similar to the layout of the ring bar of bag among Fig. 5.But, in the back of bag, collude element 20 only thereon, the lower end pastes on the bag, make collude element array on its whole length down towards the bag film.Shown in Fig. 8 A, the upper limb sealing of the bag 40 that is full of forms the bag that is suitable for adorning perishable goods, and the back seal of bag forms tear band 42, tears this off from bag when opening for the first time.Collude element 20 and only be combined in the top on the tear band 42, and have the frangible combination in top (promptly laterally delineate line or tear breach, be not shown) near the tear band position, thereby when tearing tear band off, the upper end of colluding element 20 separates with bag, shown in Fig. 8 B.For closed bag again, the bag top of reeling as required, then making stretches colludes the top (shown in Fig. 8 C) that bar 20 encases bag, engages with ring bar 24 on large tracts of land, forms main shearing load.
Two hasps also can be the whole bars of a part.For example, Fig. 9 represents closure strip 50, and closure strip 50 has whole resin matrix 52, has the monolithic molding hasp element 56 of tearing muscle 54 and extending in parallel on matrix 52, also on matrix, the fiber of ring material embeds and is fixed in the resin of matrix ring material 58.US Patent 6,202 has been described the method that forms this unitary closed bar in 260 in more detail.Parallel, continuous banded adhesive agent 60 is attached to the back side of closure strip, is used for closure strip is fixed on bag, for example, shown in Fig. 9 A.At the arrowband adhesive agent 60 that colludes on the side of tearing muscle 54 closure strip is pasted on bag face, and after filling, closure strip is pasted the coiling top of bag at the broadband adhesive agent 60 of the ring side of muscle 54.When closure strip so is applied to when bag last, closure strip 50 provides required firm closure feature, just can not open bag because do not destroy or tear closure strip.It is abandoned after it crosses bag face in order to open bag, to catch to tear muscle 54 and spur, the matrix 52 of closure is torn into two parallel parts, every part has corresponding one that can engage hasp.Matrix 52 is torn groove (not shown) what each side of muscle 54 had a shaping, helps control to open bag.After this closed bag again, as mentioned above, the bag top reeled downwards makes two snap-engagement.Because the lower edge of closure strip 50 does not paste on the bag, following hasp element freely is hinged on it and sticks on the corresponding adhesive agent on bag face, makes the orientation of face of joint be in the shearing load direction.
Figure 10 represents, is used to roll up another embodiment of the unitary closed bar 70 that pushes up bag.In this embodiment, the protruding hasp element 56 of shaping is formed in being loaded with and tears on muscle 54 opposite side opposite with ring material 58 1 sides.Be the adhesive agent 60 in broadband below ring material, and below near the longitudinal edge that colludes element, be the adhesive agent 60 of arrowband.The arrowband adhesive agent is fixed on bag face bottom with bag closure 70, makes to collude element 56 towards the bag film, shown in Figure 10 A.Broadband adhesive agent 60 for good and all is fixed on closure strip the coiling or the folding top of filling bag.When opening filling bag for the first time, catch and tear muscle 54 and pulling to tear closed matrix.After this, compacting bag face and divide by closed hook part, the below of tearing formation between the coiling top, can bag is closed again.Although this closing order needs operation simultaneously to collude partial sum coiling top, thereby generally needs two manual manipulations, this can provide the advantage of above-mentioned shearing load.And the overall permanence of closure strip becomes easily assembling, and the firm closure feature is provided.Since only after filling, closure is pasted a bag top, therefore can be according to the actual needs steady ring element of each filling bag.Like this, closed top can paste on the bag of filling, and the bag top of filling has been wound up into position very tight, that reduce the space downwards, and this is very favourable, and closure is in extended state, as same adhesive agent band.This close packing needs for transportation and the storage space removing air, strengthen sealing (for example for perishable goods) and reduce Retail commodity.
For example, the adhesive agent 60 of each the closure strip bottom in the bag can be replaced by heatsealing shown in Fig. 9 A and Figure 10 A.In this case, closure strip can be applied on the bag before filling.Closure strip can provide with continuous form, and is cut into the length of application, perhaps is cut into certain-length according to release wire and utilizes common labeling apparatus to be attached on the bag.
Should be realized that above-mentioned accompanying drawing is not limited to, but be used to schematically show the notion of claim.For example, the matrix thickness that above-mentioned closure member has usually is only for about 0.003 to 0.007 inch (preferably, between about 0.004 to 0.005 inch), but seem shown in the figure than the bag thickness many, and a bag film preferably has the thickness identical with closed matrix.Thin and deformable closed matrix particularly itself are compared for bag constructions shown in Figure 1 and with the bag film, make down closure member upwards be drawn to the shearing load direction easily.A thicker bag film has bigger elasticity, and the restoring force at bigger coiling top is provided for the reorientation of closure.The thin closure standard that also makes handles and packaging facilities is used.
Though described a lot of embodiments of the invention, it should be understood that under the situation that does not depart from spirit and scope of the invention and can make different modifications.Therefore, other embodiment is also in the scope of claim restriction.
