Description

The folding package that has inner casing, device that these package center article are packed and the device of making these packages

The present invention relates to a kind of FOLD AND PACK product that have inner casing, and the method for making this package.

In packing technique, the known various FOLD AND PACK product that have soft liner pouch, Packaging Specialty personnel claim these pouches to be " pouch in the chest ".

For some package, narrow the pressing down that the soft son bag of the inside is bonded in the delta-shaped region closed on the tongue piece.The end of Delta Region with press down the end of closing tongue piece and coincide.

The lining bag is to close by its open end is rolled in soft, and perhaps great the straight line that parallels with two broad side surfaces seals, and those skilled in the art thinks, fixedly is necessary along the axle that parallels with two broad side surfaces.Because the location of straight line is than the height that is easier to, also can reduces the son bag.

Yet there is a very big shortcoming in this package, in case because the user tears the upper end and after opening the inside pouch for the first time, this pouch just can not regain excellent sealing performance along static line.

The objective of the invention is to, provide a kind of by a favorable sealing property, and the FOLD AND PACK product of the box of reclosable and soft pouch composition, this shortcoming corrected.

The invention further relates to the FOLD AND PACK product of the reclosable that constitutes by a rigidity or semi-rigid box and soft inner casing, box has four sides and is extended with to press down closes tongue piece, the opening portion on inner casing top adheres on some point of two relative wide tongue pieces, these points be positioned at least the Delta Region within or very near the Delta Region, the end of Delta Region with close tongue piece and the corresponding formed boundary line of broad side surface coincides.

The size at the end of this Delta Region is by formula

L＝（P-2l）/2

Determine that P is the girth of the inner casing on the inner casing cross-sectional direction in the formula; L is the width of narrow side; L is the size at the bottom of the Delta Region.

The height of Delta Region equals half of its end.Along the static line that is parallel to narrow side and the top by described Delta Region inner casing is fixed.

The cross-sectional plane of inner casing might not equate with the cross-sectional plane of box.In fact, the cross-sectional plane of inner casing is significantly less than the cross-sectional plane of box, and this is for inner casing being suspended between two broad side surfaces, and not with a narrow side or an one narrow contacts side surfaces.

The ratio of the size of broad side surface and narrow side is preferably between 1.3 and 4, and broad side surface should extend the following spatula of closing again, and can not there be so following spatula narrow side.

In the package that constitutes like this, just being easy to that tongue piece outwards separates of closing that has said Delta Region closed inner casing.Close tongue piece when pressing down 90 ° outwardly when these, the open end of inner casing just presents two lip shape shapes of tightening mutually arranged side by side.Just carry out again folding then easily or seal, so inner casing is fixed on the box method of gluing particularly with any known process.

Seal along the straight line that is parallel to narrow side opposite with those of ordinary skills' method in common, yet before the user opened it first, it had the beyond thought advantage that assurance does not damage package.And can close again effectively very much, this closes the flavor perfume (or spice) that can keep article in the package.

Because the Delta Region is in wide closing on the tongue piece, and its size is very big, and this has just guaranteed the net effect of package and be well suited for soft inner casing to be folding shape and to be placed in one.

Certainly, can be constituted by the above-mentioned leg-of-mutton gross area or also be constituted in the fixed area of closing on the box by some points in the top gluing of described trigonum, yet can be constituted, for example be arranged to inverted T-shaped or in delta-shaped region, be arranged to parallel band shape by every other arrangement.

Be preferably in above-mentioned delta-shaped region in-to-in very near gluing in the zone on top, right angle, and gluing in exterior at least two zones, trigonum, these two zones all are positioned at and parallel with the end of delta-shaped region and very near the two ends of the linear portion of this bottom, so-called very near being meant that the distance between them is such, the material deformation of inner casing can eliminate the displacement that the gluing beyond the triangle causes by elastic deformation.Not on the leg-of-mutton end, but can avoid the chance of glue to overflow making pouch set on the following spatula beyond the Delta Region in two regional gluings that parallel the end of with and be lower than the bottom slightly.Extracting of inner casing occur or rupture thus or make the shaping of inner casing not good, or overflowing the position.

Inner casing can be made by the housing that forms at the bottom of that two ends are opened or an end is closed in advance.At latter event, we are with a more specific speech " pouch ".In the following description, our usefulness specific word " pouch " of using everyday words " inner casing " sometimes, having.But, other various forms of inner casings can be considered, and particularly the inner casing of chemical treatment can be used to prevent that some from corroding, and this inner shell materials will be selected according to the article in this package.

Certainly, inner casing will sufficiently exceed box; Make an end of opening arrive the top, trigonum of regulation at least, preferably exceed.

For having only unique end, particularly inner casing by having under the situation that the pouch of closing the end constitutes, can consider this mode of closing, when inner casing be two ends open hull shape the time, also can consider this mode of closing.

Inner casing can adhere on other two side tongue pieces equally, rather than is fixed on these two tongue pieces.First kind of situation, close tongue piece when launching to the outside pressing down, inner casing adheres in this Delta Region of closing tongue piece, and can causing in addition two, to close tongue piece folding again inwards.

According to first kind of embodiment, folding package only contains the inner casing of a tubulose, and the cross-sectional plane of this tubular inner casing and the cross-sectional plane of box are similar.

Though this embodiment can not obtain complete liquid-tight package, it can make the packing powder need maybe to prevent that the cost of box of the product of extraneous dust from reducing greatly, by the folding structure that has formed when sheet is packed at the bottom of the package of closing again.The tongue piece of closing that is fixed with inner casing on the Delta Region is turned down outwardly, then other two close one of tongue piece and turn down inwardly with a ground, again fwd being closed tongue piece turns down one by one inwardly at the bottom of the final plant closure box, thereafter this is closed tongue and be stained with, this just has been enough to form the structure at the bottom of the package.Then, before the other end of closing box again, just can in package, article have been loaded.

According to a kind of more clear embodiment, when two tongue pieces all are pressed onto off position, one of them close tongue have at least one can with the relative protuberance that at least one notch on the tongue piece matches of closing, inner casing does not strike up partnership at the notch position with the tongue piece with notch.When closing package, just the top of pouch is sealed.

This embodiment can constitute the energy package that relative density ground is closed again after using for the first time.In fact ought open for the first time, just can with one have a gluing trigonum close tongue piece outward to the belt that presses down and cut off by this triangle top, just realized thus unpacking, by unpacking, the dress thing deposited in the inner casing just flows out.Closing tongue piece might constitute a cleaning liquid and chew.

According to the embodiment that is changed, notch is located on the broad side surface, preferably be located at corresponding and close on the common seamed edge that tongue piece conforms to, this change is called the advantage of the package of " U.S.'s tongue piece box " with respect to known name, rigidity when the ratio of rigidity when unpacking is closed case is stronger, and for U.S.'s tongue piece box, the corresponding position that has the protuberance tongue piece causes forming on original side a belly without tongue piece, this was both ugly, and closed also very difficult again.On the contrary, package of the present invention is closed tongue and is had stronger rigidity owing to having increased, this increase close the appearance that tongue has prevented all " bellies " distortion, make rectangular section.

When closing tongue piece to what be used as that cleaning liquid chews usefulness when folding once more inwardly again, because the top of pouch is sealed, so just inner casing is clipped on the seamed edge, this seamed edge is to be made of described connection lead of closing between tongue piece and the corresponding surface, and this clamping has also just constituted a kind of method that relative leak free inner pouch is provided.Corresponding protuberance of closing tongue piece is inserted in the notch, be used for the interim fastening tongue piece of closing that is closed condition.These notches are provided with the seamed edge of closing tongue piece that has the gluing trigonum with paralleling, so that with close from corresponding that end tongue is extended and the tongue and groove tongue bars that contains said teat matches, these notches also can be arranged between two angles, are used for matching with the corresponding angle of closing tongue piece.

Certainly, the combination of other notch one teats also can be considered, thereby this does not exceed scope of the present invention.

According to preferable embodiment, the top tongue piece of closing contains one with two disclosed broken strings in zone, first zone contains the overwhelming majority that the handlebar inner casing carries out the fixed triangle district at least, and do not adhere to corresponding closing on the tongue piece, obviously, second is replenished regional corresponding the closing on the tongue piece that adhered to after box is made.

According to this embodiment, the user tears the top tongue of closing along broken string when using for the first time.After wearing out pouch, the user just can contact the article in the package, for example, a part is cut on the leg-of-mutton top of being glued, owing to protuberance can fall in the into cooresponding groove of closing on the tongue piece, so also box can be closed again.

Because double folding is carried out at the superincumbent seamed edge of inner casing position, and owing to sealing closing the tongue piece off position, so inner casing still has sealing property.

According to the embodiment that changes, box contains a window at least on one face.Simultaneously inner casing is bonded to around this window on the overwhelming majority.Thereby can see that article the package, inner casing have sealing and the effect of dress sulphur simultaneously from window.It is very low that this embodiment can be made the rate of manufacturing, the box that Packing Condition is enhanced and has the aesthetic feeling packing.In addition, even bonding undesirable around the window broken even perhaps produce on window, the leak tightness of packing still can maintain.

According to a preferred embodiment of the present invention, soft inner casing is fixed on first pair of relative pressing down closes in some zone in the triangle on the tongue piece, simultaneously also be fixed to another to closing certain zone on the tongue piece relatively, this zone at least rectangle inner become very near with the rectangle top, limit in the rectangle coincides with the intersection of closing tongue and respective face, and the height of brachmorphy is about described first pair and closes half of tongue width.

After inner casing is filled, just box is closed, two tongue pieces that have fixed triangle shape outwardly when pressing down, are pressed onto they and box height at conplane off position with regard to the tongue piece that causes having two, and the heart does not carry out other operation, these, the folding of inner casing is formed automatically, and style is very good, and not manual effect, when pressing down in the opposite direction, just close tongue to what have a fixed triangle when inwardly pressing down singly, just finished closing of box.

When using tubular inner casing.After box is made container, back cover is carried out in the lower end of inner casing just can expect sealing very good package.The following tongue piece of closing that at first will have the fixed triangle district is outwardly to pressing down, this closes tongue inwardly to pressing down under just causing in addition two, then the first two will be pressed downwardly onto certain position inwardly by the bonding tongue piece of closing entirely, this has just finished closing of box very ideally, and need not glue processing.The end that is constituted is perfect like this, and without any discordant folding line.After package is filled, use the same method the other end of package is closed.

Package preferable embodiment according to the present invention, box has two relative faces, and these two faces contain with face and press down the perpendicular medial launder of intersection of closing tongue.

Using before them, can flatten package along two medial launders becomes flat boards.When being exerted pressure in the side, just very simply box has been made container perpendicular to the direction of two medial launders.When inner casing used the pouch at the end of W shape to constitute, this embodiment was very successful, and it has prevented the torsional deflection when making container.This torsional deflection should be avoided, because it is restricted the intensity at the bottom of the pouch, and this also is inaesthetic in any case.At present, to having only four seamed edges and not finding any method that prevents torsional deflection as yet with respect to the conventional box that cooresponding two seamed edges of box are crushed.

The box of known form is made container, be that these two sides are become " container " position by " plane " position in the process of rocking, so-called " plane " position is meant that the angle between the side adjacent with them, these two sides is 0 °, and " container " position is meant that the angle between these two sides and their adjacent side is 90 °, and its cross section is transformed into the square-section step by step from very flat rhombus " plane ".

Will adapt to this transformation with the side at the bottom of the incorporated pouch, this transformation can produce shearing effect when box is made container, the acquisition at the end that this shear efficiency influence is smooth.The distortion of bearing at the bottom of the pouch can have been moved complex-shaped hidden hole humorous folded trace on good terms, and forms unwelcome cave.

On the contrary, for package of the present invention, no matter box is container-like or tabular, two do not have the relative face of medial launder still to be in position face-to-face and parallel to each other.So the constraint of shearing force is not born at the end of pouch at all.Two faces that have medial launder are folding symmetrically at the medial launder place, and this is because square-section originally progressively becomes hexagon along with box is pressurizeed.

In the bottom of box, the part of W type can compensate the gap of being caused by the limit of the face that has medial launder.

Obtain the water operation of such pouch from operation.With the plastic film of common reel, by just can forming housing along the folding described film of its axis, make the lower part of frame moulding with the groove shape thing in a manufacturing W type cross section after, firmly and pouch scale off with the hot thin plate of a motion underseal again from film with pouch.

Can make it become flat board or become container at an easy rate according to the made package of the scheme of this change, and the package packing machine of using it for form known does not have hell and high water yet.

Scheme according to another change.Above basic big or small consistent with the cross-sectional plane of box of size of big tongue piece.This big tongue piece has a fracture straight line that is made of line segment, and this straight line parallel is in main seamed edge, and the triangle by gluing, the top edge of big tongue piece above this triangle is linked by two curvilinear lengths again, and described fracture straight line defines and draws back part.

Correspondingly big close tongue piece by forming this antimeric shape and the tongue piece shape basically identical of being extracted based on two parts that are symmetrical in center apportion broken line.Top big tongue piece is bonding along side, and it is extracted the symmetric part that partly has at least a part to adhere to the outside of following big tongue piece and gets on.

Thereby this has just formed the package that cleaning liquid with Reclosable is chewed.Equally also can prepare a metal liquid cleaning that matches with box and inner casing on a side chews.

According to the specific embodiment of a same inventive concept, inner casing is adhered on the big tongue piece of before having pointed out.

Inner casing can adhere to the arbitrary region of another relative big tongue piece, and these zones are the outside of defined Delta Region in front.The big tongue piece of this of back contains the corresponding folding groove in two limits with the previously defined structure Delta Region that falls, and its degree of depth equals the height of Delta Region at the most.

When two big tongue pieces outwards when pressing down, be bonded at outside the Delta Region institute of the inner casing in zone applied pressure and just caused because of existing, folding groove and bending in the big tongue piece angle that is allowed to for inner casing is sealed, is made the lip shape and is anticipated for reason.

Roll over the turning-in of groove and tongue sheet elder generation having then, and close tongue lid, in order to keep an appearance that ideal is attractive in appearance by other.

The invention still further relates to the device of article in this package of packing, when closing tongue piece greatly to external pressure, this device contains the equipment of sealing along by apex bundle of lines inner casing open end.

The invention still further relates to the device made from above-mentioned arbitrary different embodiment same package product, this device contains and removes the equipment that is bonded at the film on the cut paper inside face at least in three zones, these three zones are among virtual triangle or very near triangle, the leg-of-mutton end and close tongue and the intersection of side and corresponding side is consistent greatly, its size is by equation L=(P-2l)/2 determine, P is the cross-sectional plane of inner casing in the equation, l is the width of narrow side, and leg-of-mutton height is half of the end.

Other advantage and embodiment will be described in detail by accompanying drawing, among the figure:

-Fig. 1 is the top view section-drawing that has the box of inner pouch;

Transparent view when-Fig. 2 closes for package of the present invention;

-Fig. 3 is the top view section-drawing of the embodiment of the present invention's change;

-Fig. 4 is the top view section-drawing of the embodiment of another change;

-Fig. 5 is the transparent view that has the clean box of chewing of liquid spray.

FOLD AND PACK product of the present invention, package for example shown in Figure 1 are made of box (1) and soft son bag (2), in described embodiment, the top of soft pouch (2) be open and the lower end is closed.

It is made of the transparent plastic material of polyethylene or polypropylene type.Equally also can be by every other flexible material, for example paper, aluminium, aluminum-clad plastic material are made.The selection of material should be according to the physicochemical characteristic of being studied: aeroseal, ash sealing, coal gas sealing, anti-chemical reagent.

Son bag (2) is from the soft cover of common reel, cuts thin plate with heat and cuts off soft housing and make foldable bag, by plastic film self the formation bellows that collapses, later on its limit is sealed.Thereby just can obtain the pouch of desired size, promptly in described embodiment, its cross section conforms to the cross section of shaping box (1), its highly to the height of the side (5) of group box (1) and close the height of tongue piece (9) and the box height 1/10th and.

This exceeds part and is used for that the end of opening to pouch (2) seals after loading article.The most handy cardboard of box (1) is made.Particularly have the cardboard or the solid cardboard of stria.Box also can have opening, for example has the window of transparent rigidity or transparent semi-rigid lid.

Box has two broad side surfaces (6) and (8), also has two narrow sides (5) and (7).One of them broad side surface (6) contains and the corresponding tongue piece (10) that is connected of the join domain (14) of gluing, and zone (14) is positioned on the corresponding side surface (8).

Side (5,6,7,8) is contained respectively in their upper end to press down and is closed tongue piece (9,10,11,12).

Broad side surface (6,8) on top has big tongue piece (10,12) respectively, and narrow side (5,7) have tab (9,11) respectively in the above, preferably be used to be slightly larger than big tongue piece (12) toward the size of the big tongue piece in top (10) that presses down before at the big tongue piece in corresponding top (12), and this can make second big tongue piece in top (12) folding easily.

Big tongue piece (10,12) has the zone of gluing, the gluing zone is arranged in virtual equicrural triangle (24,26) or close equicrural triangle place, first zone of gluing (100,200) is positioned at triangle (24,26) to be located near upper end (101,201), and the angle of top (101,201) is 90 °.

Two gluing zones (102,202) and (103,203) are positioned at the below of described triangle (24,26), (104,204) in addition, are in the termination of the virtual line section (105,205) that parallels with the said end.Distance between the end (104) and the line segment (105) is very little, mostly is several millimeters the order of magnitude most.Certainly can be different by the morphology of gluing with described embodiment, this does not exceed scope of the present invention.They also can make the inverse-T-shaped shape between three zones that define, perhaps gluing on whole delta-shaped region in the above.

In described embodiment, what pouch equally also can adhere to tab (9,11) is positioned at rectangle (106,206) some zone of in-to-in, and for example these zones (107 to 110), (207 to 210) are on four jiaos of described rectangle.

Splicing tape (301 to 305) with axial placement adheres to pouch on the side, only carries out bonding along a limit of each seamed edge (306 to 308) with the inside face of Bedpan.

Fig. 2 represents to close the package of tongue piece (9 to 12) when closing, close tongue piece (10,12) along direction shown in the arrow F outwards when pressing down, just caused closing tongue piece (9,11) and inwardly closed up along the direction of arrow F '.The super interior pressure that is produced on the upper tongue (9 to 12) of box that bonds in inner casing of this mobile generation.That part that exceeds triangle (24,26) top of pouch has formed the parallel lip of two parallel lips (35,36) and can be bent and be pressed onto above the box before two following spatulas (10,12) be closed.Perhaps also available flatiron is sealed it.If these two lips (35,36) have been sealed, then can obtain airtight and all desirable the closing of watertight.

In addition, according to specific embodiments shown in Figure 3, the cut paper of cardboard contains two grooves (20,21), and these two grooves extend along the line of centers of broad side surface (6,8) respectively, and reaches (12,18) upward continuity at the wide tongue (10,16) of closing that makes the groove lengthening respectively.To close tongue piece (9 to 12) and (15 to 18) revolution superimposed before, these two central channels can make box almost be rendered as hexagonal cross-section, the plane by two grooves (20,21) to each other fully flattening also be like this.

On the contrary, when box was made container, medial launder (20,21) was positioned in the plane that is formed by cooresponding two broad side surfaces (6,8), and medial launder is also owing to folding folding this phenomenon in side that prevents to top tongue piece obtains sclerosis.

At first use adhesive tape (22) that soft pouch (2) is adhered on the cut paper of box (1), adhesive tape is parallel with folding groove (19) and be provided with the not belt of gluing of a long narrow table mm wide along described folding groove (19).The geometric configuration in gluing zone provides according to explanation.And, whole side height and whole folding bag are being carried out in the scope of gluing, can replace the geometric configuration in gluing zone with difform zone, and the folding bag of this moment is flat.But this does not change function of the present invention.Equally, only have several gluing points and be fine yet, still, the last package of making is very not satisfactory.

When the cut paper that pouch is not had lid partly be pressed onto the plate cassette structure pouch have on the cover time, other adhesive tape (22) is just collided with following pouch.

The bent around that does not have cover groove (20,21) of these pouches.

In addition, cut paper has broken string (37), broken string comes having divided near first zone (38) of side (6) with described side (6) corresponding second zone (39).First zone is included whole or most at least triangles (24).Gluing is promptly given with cooresponding to close tongue piece (12) be freely in this first zone, and on the contrary, second zone (39) will adhere on the corresponding tongue piece 12 that is covered by it, and tear the later original state that still is in of broken string (37).When box was made container, second zone can be prolonged by the tongue and groove tongue bars (40) that matches with notch (41), and groove 12 is (8) last or corresponding upper tongue (12) in the side.

When using for the first time, the user tears first zone along broken string (37), can open the loam cake of box.This moment, he just contacted the article in the inner casing, particularly contacted pouch.Be pressed onto off position at superincumbent tongue piece (9 to 12) again, also two big tongue pieces (10,12) are incorporated into a time-out by salient that is in first zone (38) one ends and the notch that is formed on the corresponding tongue piece (12) simultaneously, just can close box again.Inner casing do not adhere to this notch (43) around, this is for protuberance (42) can be slided between box and inner casing.

Can design the protuberance (43) that can combine with notch (43) of many other geometric configuratioies, this does not exceed scope of the present invention.Especially this protuberance can be made with the rectangle that can match with notch or trapezoidal first regional angle, and it is tilting that they close the line of centers of tongue piece (12) in correspondence toward each other.

According to specific embodiments of the present invention shown in Figure 4, cut paper is owing to two parts that for line of centers (44) are symmetry are formed, and line of centers is on the end of box.Because two grooves (20,21) are divided into two parts to side (10,12), the part of two outsides (45,46) can be in order to combine with additional side (47,48).

In the embodiment shown in fig. 4, cut paper contains first window (48) on the side therein, and in addition two windows (49,50) be that the center is provided with window (48) all each other, can see from these windows and article the inner casing also can improve the outward appearance decoration of package.

Making package of the present invention carries out in order to following method:

-at first the cut paper with the box unanimity is placed on the assembly machine,

-needing to coat glued membrane on the zone of gluing with gluing machine then,

-soft pouch is placed between the groove (20,21) on the cut paper of glue last more thereafter, seamed edge is linked to each other with going to the bottom of soft pouch, this seamed edge has been determined scope at the bottom of the box.

-not covering pouch on the cut paper but have a part that connects tongue piece (13) and fold on the part that has pouch of cut paper, on then the another part that does not cover pouch being folded into the first that has pouch and is connected tongue piece.

Flat box according to making like this just is adhered to pouch on all gluing zones, and these gluing zones place on the side and close on the tongue piece.Like this, just can preserve and sell being flat box.Box is with regard to moulding when applying side pressure on to the big sidewall (6,8) that has central channel (20,21).

Box is the square-section, guarantees its body by closing tongue piece (15 to 18) under the handle to pressing down.After with soft inner pouch (2) filled with articles, closing tongue piece (10,12) greatly outwards separately and will (1) close tongue piece (9,11) when keeping the pass gate position, the top tongue piece of having finished package shuts away.The lower edge superelevation of pouch also forms two lips mutually arranged side by side, and these two lips are sealed it with two heating plates.So just obtained more satisfactory sealing property.The less tongue piece (10) of closing that to close greatly then in the tongue piece is folding on the uvula that has been pressed down, simultaneously it is clung and close greatly maximum in the tongue piece close tongue piece (12) stick on it above.

Fig. 5 represents to have the transparent view that constitutes the package of chewing of closing tongue that the clean liquid of spray uses.

The maximum tongue piece (12) of closing is being opened, and cut-out is with belt that the upper base of box (1) parallels the time, package also will be cut the top of the equicrural triangle of gluing (26) by breakdown.Close tongue piece (9 to 11) and be maintained in its closed position for other three.The cut paper of closing tongue piece (12) and pouch (12) is provided with a hole, liquid can be gone out in addition by this orifice flow, the liquid weight that acts on the side (8) has caused a same dark groove with medial launder (21), and this groove can make liquid carry out suitable flowing at an easy rate.

Fig. 6 represents to have the tangent line of the collapsible package product that can close the clean mouth of chewing the body fluid body of spray, and the difference of it and above-mentioned cut paper is to close greatly tongue piece (10,12).Big tongue piece (10) is regarded as below, because after the box of package was shaped, this big tongue piece will be covered by relative big tongue piece (12), just claims that thus big tongue piece (12) is top big tongue piece.

Should extract part (66) by top big tongue piece (12), this is extracted part and limits its scope by broken string (60).Line of rupture (60) have one parallel with main seamed edge (62) and disconnected (61) this broken string (60) of line of triangle being separated at the place of portion on the upper side of bonding triangle (26) and above close greatly on the tongue piece (12), two points by broken string (64,65) join, extract part for trapezoidal, the trapezoidal big end with above close tongue piece (12) outward flange (63) coincide.

Close tongue piece (10) down and be made up of two parts (67,68) of symmetry, the shape of these two symmetric parts (67,68) is identical with size, and two parts (67,68) of symmetry by graduation broken line (69) separately.

At first will close tongue piece (9,11) for a short time when pressing down, and close tongue piece (10,12) greatly outwards separately, this just makes the work of closing carry out.They force, and pouch (2) is correct to be shaped.Then the following tongue piece (10) of closing is greatly depressed, the more top tongue piece (12) of closing is greatly depressed, just push the upper part (68) of symmetry to back thus.

Final when box is closed, successively with symmetric part (67,68) with extract part (66) and stack in proper order from the bottom up.

On the inside face of extracting part, the more top tongue piece (12) of closing is greatly adhered to its lateral edges (70,71) is corresponding and closes for a short time on the tongue piece (9,11) in addition.

The part (66) of extracting that is connected on the symmetric part (68) is applied one and just can open the package made from the perpendicular pulling force in big side (6).Pull out with regard to the angle that requires a pouch (2) then, earlier following following symmetric part (67) of closing tongue piece (10) is greatly outwards collapsed, pull out extracting part (66) and top symmetric part (68) more at last, this just can make the angle of pouch (2) be pulled out, and having constituted a hole thus, from then on the liquid of splendid attire or particulate just flow out in the hole in the package.

When falling the thing of adorning in the box, the box of the package of doing according to this change and box shown in Figure 5 are similar.

Closing again of box is very simple, symmetric part (67) inwardly toward pressing down, and the top edge of symmetric part (67) is with to extract line (69) consistent, this top edge can be slided with respect to the top remainder of closing tongue piece (12) greatly, and especially the line segment (61) that parallels with respect to main seamed edge (62) slides.And symmetric part (67) still is in the closed position of closing, and it can guarantee the relative sealing property of package.

The present invention is subjected to the appearance of above-mentioned embodiment and embodiment restriction anything but, can extend to all the change styles that can expect that can obtain same effect on the contrary.
