The specific embodiment

The object of the invention is to solve to relate to from container and stores and the problem of distributing such as the product of paper handkerchief and hygenic towelette.As the exemplary description of whole accompanying drawing, the invention provides a kind of storage and dispense container 20 that is used for product 22.Product 22 can be various types of article, such as the article of paper handkerchief, hygenic towelette or the single distribution of other needs.Container 20 generally includes a flexible pouch 30 that is used to store product 22 and one and is used for the allocated product and the rigid flip top 50 of airtight container more subsequently.This bag 30 comprises a bottom 32, and sidepiece 34 is linked on the bottom 32, and each survey portion is connected with adjacent sidepiece, and sidepiece stretches out from the bottom.As shown in the figure, this bag is a rectangle, but it also can be other different shape, as long as the bottom is connected at least one sidepiece (for example, sidepiece is a cylindricality).Sidepiece 34 also is connected on the top 36, and the top is positioned on the bottom.Preferably, the top is parallel with the bottom usually, but and nonessential.Top 36 comprises a removable part 40, this removable part 40 under first situation (referring to accompanying drawing 1, promptly before product is assigned with for the first time) product in the sealing bag, and allow under second situation (promptly to be removed when removable part, rigid flip top 50 is positioned at open mode, as shown in Figure 5, rigid flip top 50 paste shown in Fig. 1-4 the bag 30 on)) near the bag in a product.Removable part 40 can be the die cut oval (as shown in Figure 1) of perforation, the scored material of different shape, and can comprise traditional resealable label therewith." top " as used herein, " bottom ", " sidepiece " are only determined each parts another position relatively, do not limit scope of the present invention in addition.

For example referring to Fig. 3-7, rigid flip top 50 comprises that one is connected to lid 52 on the edge 54 through hinge 56.This edge pastes the outside face 38 of (can further discuss this point herein) bag on the top 36 of bag, so rigid flip top is superimposed upon on the removable part 40 of bag, removable part is centered on by rigid flip top on the outside face of bag.Rigid flip top can be partially or entirely affixed to top 36, or the part of rigid flip top 50 also can paste a sidepiece, as long as lock pin 60 adjacent top settings.Edge 54 forms a distribution openings 58, and product distributes by this distribution openings 58 when lid is opened.This edge can comprise that the strengthening rib 55 that centers on the edge is so that strengthen this edge as desired.Lid 52 can be arranged to closed (example as shown in Figure 3-4) so that engagement edge with removing, thereby and sealing bag on the outer surface, and removable part is centered on by rigid flip top at this, after removable part 40 is removed, and when under a special distribution condition, not wishing to want other paper handkerchief, in the above described manner around the bag outside with bag and the sealing of the product in it.Lid 52 comprises the annular sealing ring 51 that stretches out of inboard away from lid downwards, and the size of this ring 51 is designed so that cooperate away from the inboard upwardly extending annular sealing ring 53 in edge relatively, thereby helps to cover the better sealing with the edge when covering closure.

Will address below the various supplementary features of the present invention.These features can be used separately or in conjunction with part or all of use described herein, utilize the present invention in every way according to wish.For example referring to accompanying drawing 5 and 10-13, in these features one relate to cover 52 with edge 54.Lid comprises that a lock pin 60, lock pin 60 have the outstanding elongated first rib 62 of a level, and the edge comprises a latch hook 64, and this latch hook 64 has the outstanding elongated second rib 66 of a level.First rib and second rib 62 and 66 can be engaged with each other lid being remained closed (for example referring to Figure 13) movably with interference fit respectively, and discharge each other movably when lid is opened.Advantageously, at least one in first and second ribs 62 and 66 has elongate cross-section heterogeneous (being that section heterogeneous is determined along the length direction of rib) respectively.This heterogeneity as an example referring to Figure 10-12.Like this, for example interference that reduces gradually of rib section (promptly because outstanding thickness and/or the quantity of level) (for example right side among Figure 10) on lock pin one side provides still less material, thus reduced overcome with latch hook on the required power of rib interference fit relation.As shown in figure 10, near middle, rib 62 has evenly elongated section along the lock pin length direction, if desired, can provide audible click to cover on the edge closed fully with expression.In addition in this, the significant advantage of another of this non-homogeneous rib feature is unique lock/hook relation, this relation make when opening tongue piece 74 towards the crooked lid of aperture position, rather than the interference fit that must overcome whole lock/hook simultaneously to be when discharging these two parts, lock pin leaves from hook.

Be shown specifically as Figure 11-12, rib 62 and/or 66 heterogeneity can also be restricted to (for example taper) elongate cross-section of band angle.Selectively, or additionally, the elongated first rib of lock pin can cover relatively periphery in the level of lid on inwardly outstanding (for example referring to Figure 10), the elongated second rib of latch hook can be on the horizontal surface at edge the periphery outwards outstanding (for example referring to Figure 13) of opposite edges.Still selectively or additionally, first rib can have an elongate cross-section heterogeneous (for example referring to Figure 10), second rib can have a uniform elongate cross-section (being that this is referring to the rib among Figure 10, if it has the cephalocaudal identical section shown in Figure 11).

In these features other relate to and cover 52 and opening tongue piece 74, for example referring to accompanying drawing 3-5, and 15 and 17." opening tongue piece " is restricted to away from the hermetic unit of rigid flip top from lid radially outstandingly herein, and the user is placed between outshot and the flexible pouch when with box lunch lid being shifted to open position in order to will cover any part of the lid that separates from the edge to their finger tip of major general.The opening tongue piece is outstanding from rigid flip top 50, so the user can more easily find it and a more discernible leverage points be arranged to open lid.By the opening tab off-center (for example is provided with, the left side of bisector 76-76 or the right, perhaps selectively, the left tongue piece of bisector 76-76 and a right tongue piece), particularly at least eccentric 60%, better at least 70%, at least 80%, at least 90%, best 100%, this set of opening tongue piece, benefit are the size maximizations that can be used near paper handkerchief and the distribution openings 58 being convenient to distribute.The size of distribution openings is that the area piled up of paper handkerchief in the bag (wide and long) deducts and is used to produce a bag material, removable part, paper handkerchief is piled up and the edge pasted the function of the production tolerance on the bag.If opening tongue piece 74 and conventional package are set at the center of rigid flip top similarly, the size of distribution openings (being allotment area) has just been reduced unfriendly by the outstanding length of opening tongue piece, this length exceeds the periphery of lid so that the periphery of rigid flip top can be remained on the periphery inboard of container, in the production tolerance of the acceptable container of these needs and customer's the acceptance (being about to is the non-popular opening of not noted).And, be not limited to a kind of theory of operation, by the off-centre setting of opening tongue piece, for the given force that is applied on the tongue piece, the moment of torsion of opening lid that is generated will increase.The result of this increase makes can be more easily (promptly by still less power) opens lid.

Referring to Figure 17, lid is limited by length 70 and width 72, and length is defined as greater than width (in the also promptly long and wide horizontal surface that is determined to be in lid respectively around each limit of the maximum rectangle of lid formation) herein.If long and wide equating, so arbitrary size all can be used as long and wide at this.Lid can also limit by a horizontal perimeter with from the outwards outstanding opening tongue piece 74 of periphery.Opening tongue piece (also promptly, the formed point of leverage of opening tongue piece) at least advantageously is set at the length mid point on the either side of the bisector of the width of lid.As shown in figure 17, being used to cover such bisector of 52 can be the line 76-76 that the width at length mid point upper edge lid is provided with.Usually, for the lid of other shape, bisector can be determined by being provided with perpendicular to the bisector of lid length (length that is limited as mentioned) at the length mid point.More advantageously, opening tongue piece (also promptly, the formed point of leverage of opening tongue piece) at least can be arranged on the width mid point is provided with bisector along the length of lid hinge-less side again.As shown in figure 17, being used to cover 52 this bisector can be the line 78-78 that is provided with along lid length at the width mid point.Usually, for the lid of other shape, bisector can be by determining perpendicular to the bisector of lid width in the setting of width mid point.Selectively, or additionally, opening tongue piece 74 can comprise that being arranged on the opening tongue piece is adjacent pit 80 (for example Figure 15) between the outside face, and this pit 80 helps user grasping edges when opening the opening tongue piece.Selectively or additionally, except opening tongue piece 74 outwards outstanding peripheries, lid can be essentially identical simple geometric shape (for example circle, ellipse, triangle, rectangle, pentagon, hexagon, a heptagon etc.).

Other features relate to hinge 56, for example referring to Fig. 5-9.People often wish to have a snap-type opening hinge.This hinge can be a hinges, " hinges " expression that herein limits and the integrally formed hinge of element of both sides.As shown in the figure, this element for example is to cover 52 and edge 54.Hinge comprises a center band 92 and a pair of wristband 94, and each wristband is arranged on the opposite side of center band.Advantageously, hinge can make to cover at whole first aperture position and move (for example about 90 degree that limited from about 0 degree to the same relatively horizontal surface that relative horizontal surface limited).Subsequently, lid overcomes the power that center band and double-type wristband produced through the mobile needs of first aperture position, any pressure release point of about 180 degree that about 90 degree to the same relatively horizontal surface that limits from same relatively horizontal surface limits), when this power is overcome, lid remains on second open position, any position through pressure release point, for example about 135 of same relatively horizontal surface spend, allow lid to open about 30 degree more subsequently at this place), thus the lid radian in second aperture position is greater than the radian of the lid in first aperture position.From second aperture position lid is moved to closure state and need overcome power on the reversing sense, this reversing sense is a direction of shifting to second aperture position when lid from first aperture position.

Be not limited to a kind of understanding mode, the snap-type opening characteristics of this qualification first and second aperture positions for example obtains referring to Fig. 7-9 as hereinafter.Center band 92 forms a S. A., the effect of this very similar a kind of mechanical hinge at the middle part that it is connected between the lid and the two ends at edge.Wristband 94 is positioned at the both sides of center band and is arranged on the horizontal surface (for example referring to Fig. 8, wherein the horizontal surface of center band is lower than the horizontal surface that holds wristband) that is different from the center band.Because the natural elliptic geometry shape of rigid flip top, wristband is than the bigger distance of hinges rotation, and when cap closure, from lateral plan, wristband is compared the more lateral that the center band is arranged on the rigid flip top periphery.So, when cap closure, wristband is in the slight compression.In case lid is opened, the feathering axis of wristband moves towards the feathering axis of center band.When these took place, wristband was in the tensioning and the extended state of increase, moved past the feathering axis of center band until the feathering axis of wristband, and the feathering axis of wristband moves into position one loose, original shaping.By being closed in the range of movement of opening fully, along with the increase of tension force on the wristband, increase to peak value and reduction fast at lid, this motion just produces spring/snap effect.

More particularly, hinge can be restricted at least one wristband and comprise pair of channels, and this passage has the second channel 98 on second end of band of first passage 96 on first end of the band that is arranged on contiguous lid and neighboring edge.Like this, wristband so more helps the buckle opening characteristic at the end pivot of the middle both sides of similar middle band.Still selectively or additionally, when lid is closed, comprising that the whole hinge of the thickness that adjoins contiguous lid of hinge and edge has a thickness, increase arrangement by advantage, is to be not more than about 4cm, about 3cm, about 2cm, about 1cm, or the thickness of about 0.5cm.

Another feature relate to cover 52 with the relation at edge 54, for example referring to Fig. 5 and 18-23.This feature is particularly conducive to and the combining of snap collar opening characteristics because lid and edge rigidity help the safety of buckle opening characteristics, special because rigid flip top pastes on the flexible material that forms bag.And selectively or additionally, be not limited to a kind of operating mode, the lid and the rigidity at edge, particularly when the rigidity at edge when covering, more help between edge and flexible pouch the viscous force that keeps good, prevent better when opening rigid flip top that the edge from peeling off from flexible pouch with box lunch.In this, lid can have first rigidity value (as qualification herein), and the edge can have second rigidity value, and first rigidity value is greater than second rigidity value.This first rigidity value is the value of covering on length or Width, and second rigidity value is the value of edge on length or Width.In any case above-mentioned, be favourable greater than second rigidity value at least one size of the length at edge or width at the length of lid or first rigidity value at least one size of width.Additionally or selectively, increase according to advantage and to arrange, first rigidity value is at least greater than the second rigidity value twice or at least greater than three times of second rigidity values, or at least four times, five times or be favourable for six times greater than second rigidity value at least.The rigidity of edge and lid for example is by the type of institute's materials used, the thickness of component, composition ratio, component structure and the others well known by persons skilled in the art decision of rigid area and entire area (promptly comprising at interval and the hole).

Rigidity value test method (referring to Figure 18-23)

Sample preparation is by following order: differently state that all tests all are to carry out under TAPPI (U.S.'s paper pulp and paper industry technological associations) reference conditions unless have.Hinge intermediate point between lid and edge is divided into two with rigid flip top, and its function does not have substantial variations when rigid flip top is used before separated.This separation can use scissors, knife, saw, any instrument or other can with lid separately and can the arbitrary assembly of apparent damage from the edge instrument.Referring to Figure 18, test sample 100, for example cover, sentencing certain mode (for example using screw rod, clamp etc.) at attachment point 150 is fixed on the L bracket 200, to prevent that test sample from moving with respect to attachment point except that vertical direction, the mobile of this vertical direction caused by test probe, and is unlikely the function of obvious change rigid flip top assembly, because they may be used before so fixing.Little screw (diameter is not more than 1/8 inch) can be used for the restraint test sample with attachment screw.When measuring rigidity value with respect to specimen width, attachment point is arranged in the scope of sample periphery inboard 5% to 10%.When measuring rigidity value with respect to sample length, fixing being arranged on surely in peripheral inboard 3% to 7% the scope of sample.Distance between the inner side edge 152 of attachment point 150 and L bracket 200 is 5mm.When sample was the edge, it should be positioned in supine direction with respect to the equipment shown in Figure 18, and sample face up is away from the face of flexible pouch when rigid flip top is fixed on the flexible pouch for use.When sample is when covering, it should be positioned in ventricumbent direction with respect to equipment shown in Figure 180, and sample face down is to be fixed to for use on the flexible pouch when the rigidity overturn cover, and lid when being positioned at make position towards the face of flexible pouch.

Process of the test, in the following order: test is carried out on a standard tension experimental engine, this experimental engine is such as MTS Sintech 1/G experimental engine, it has TestWorks 4.07B software, wherein MTS is as MTS Systm Corp. and known, 14000 process drive, Eden Prairie, Minnesota (Minnesota) 55344-2290.Referring to Figure 18, L bracket 200 is sandwiched in the clamp 300 of experimental engine, and test sample book 100 is perpendicular to probe 500 (that is, in horizontal surface on the other side).Referring to Figure 19, probe 500 is made of solid aluminum, and has uniform diameter 1.27cm, and it is most advanced and sophisticated that a length A 11.43cm and a ball-shaped touch smooth circle.The threaded portion 520 that it is 1.0cm that probe has a length B.Threaded portion 520 is suitable for screwing in one 25 newton's force transducers 400.Probe 500 and threaded portion 520 relative ends are the circles with 0.635cm radius.As shown in figure 18, the center of probe 500 is provided with apart from the distance L of the inside 5mm in edge of test sample book 100 relative fixed points.Probe 500 descends subsequently, until the power engaged test sample 100 with 1.5 grams.This has determined the initial point of test.The crosshead speed setting of probe 500 is 0.2 inch of a per minute.Probe 500 is triggered, so move downward with the speed of 0.2 inch of per minute.Probe 500 is stopping after the operation 10mm distance downwards, promptly measures from the test initial point.For each running of test, the peak value-gradient on the relative deflection curve 10mm of the load distance is recorded on computers by the software program that uses TestWorks 4.07B version.Along with sample is positioned to measure its width dimensions rigidity value (being that probe and attachment point are provided with the relative edge of sample along bisector 76-76), the sample preparation (is promptly tested the same parts of rigid flip top with 5 new samples that process of the test is recycled and reused for the same parts of rigid flip top at every turn, but test with a new samples, for example each edge or lid, in 5 each all repeats), result's quilt of combination is average so that peak value-the gradient on the relative deflection curve 10mm of the load distance of definite 5 test sample books.Along with sample is positioned to measure its length dimension rigidity value (being that probe and attachment point are provided with the relative edge of sample along bisector 78-78), use above-mentioned steps, the sample preparation is done with process of the test.

Result: adopt with respect to its width, be used for the load at edge and the relation curve of deflection curve, as shown in figure 20.Point B represents the beginning of data gathering.Initial 20% position that is collected of all data points during some M represents to test, promptly put total strong point between B and the M in representing to test collected all data points initial 20%.Subsequently, " peak value-gradient " used herein limited by the gradient of line BM.Peak value-gradient in this example and thereby the rigidity value at the edge on width dimensions be every millimeter 4.3 gram force (gf/mm).For the edge, the load of relative its length of employing and the relation curve of deflection curve are as shown in figure 21.Peak value-gradient in this example, and thereby the rigidity value at the edge on length dimension be every millimeter 2.3 gram force gf/mm.For lid, the load of relative its width of employing and the relation curve of deflection curve are as shown in figure 22.Peak value-gradient in this example, and thereby the rigidity value of the lid on width dimensions be every millimeter 26.5gf/mm.For lid, the load of relative its length of employing and the relation curve of deflection curve are as shown in figure 23.Peak value-gradient in this example, and thereby the rigidity value of the lid on length dimension be every millimeter 11.0gf/mm.This has just finished the test method of rigidity value.

Shown in Figure 20-23, for example Gai peak value-gradient is greater than the edge, even when width or length direction comparison with length direction and edge.For example, use this rigidity value test method, and use according to rigid flip top of the present invention, peak value-gradient of covering in its Width can be 26.5gf/mm, and the peak value-gradient of edge in its Width is 4.3gf/mm.The rigidity value of this expression lid is greater than six times of edge stiffness values.
