The first bar of o, outer surface are sealed to antetheca, and

The second bar of o, outer surface is sealed to rear wall；

Sack defines the internal volume for food, which has between sack bottom and single opening The height of the determination of measurement.

Background technique

In general, among (for example, made of determining semi-rigid plastics material) the first bar and the second bar At least one bar includes top edge and lower edge (closed system of landscape configuration).

For example, disclosing such flexible bags in file US2014/0120207.Although apparatus can have Packaging bag, but this apparatus is usually toothpick, knife or similar plane apparatus.The apparatus cannot be stored in such as known rigidity (for example, rigidly holding refering to disclosed in US8651311 or WO2008/041808 in the internal volume of packaging bag in container Device).

It needs to make the flexible bags equipped with consumer products that there is user-friendly feature.

Summary of the invention

Therefore, the packaging bag container reclosable it is an object of the present invention to provide one kind, especially organ type packaging bag, Since manufacturing process is simple, so presenting user-friendly characteristic, and equally firm at least as conventional organ type packaging bag.

For this purpose, the purpose of the present invention is a kind of flexible bags of the above-mentioned type, wherein among antetheca and rear wall At least one wall defines the bracket of determining bar, and the bar of the determination includes contact portion outstanding, described outstanding Contact portion is suitble to be used in combination with measuring appliance, and contact portion outstanding extends below the interlock region of closed system completely.

The bar of determination with protrusion be by the first bar and the second bar at least one of item Shape object defines, or can be different from closed system.In the case where different from closed system, determining bar is substantially flat Row is laterally extended (thus defining top edge and lower edge) in closed system in sack.Contact portion outstanding is preferably couple to The lower edge of the bar of the determination.

Advantageously, contact portion outstanding:

In at least one base part (can be proximal part for interlock region) and at least one free margins Between extend, the free margins be preferably interlock region distal end (more farther than base part) identical free margins；

Belong to the bar part not in conjunction with sack；And

At least one element smoothed out in element and holding element is defined, to keep the one of elongated measuring appliance The length of a end, the elongated measuring appliance is less than determining height.

In other words, wherein at least one bar possessed by the closed system of flexible bags is furnished with special tongue-like part It is divided to or similar contact portion (may be defined by two prodgers spaced apart), the special ligule part or similar connects Contact portion point is prominent towards content, and matches and/or keep the characteristic of measuring appliance with cup-shaped.Packaging bag is used in particular for herein Powder food product (but being also possible to wet product), including in the accessory for defining the top being individually open.

Because free margins can far from sack inner surface, user be easy to contact portion be used as smooth out element and/or As holding part, measuring appliance therefrom can be stored and take out repeatedly (by direct gripping handle, with food or other contents It is separated by a distance).Contact portion outstanding is usually the resiliently deformable member of ligule, sufficiently prominent from the lower edge of closed system Out, so that being smoothed out with bag sidewalls place separated by a distance.Since contact portion is flexible, so using Person need not nearly vertically tilt measurer, and some products can in this way dropped out and therefore causes measurement inaccurate.

According to special circumstances, packaging bag can have closed system, enable to be particularly easy to a special measuring tool or non-dedicated The internal volume of measurer return package bag, fetches the device when can use afterwards so as to user, limitation produces at the same time The risk of product pollution.

According to selectivity or the special circumstances of complementarity, packaging bag can have closed system, enable to utilize protrusion The free margins of contact portion be particularly easy to smooth out special measuring tool or non-dedicated measurer, make its just side on the contents, and Below the plane of the opening defined by closed system.Herein, it should be appreciated that closed system can be operated by any mode appropriate, It is possible that being not necessarily to any anchoring element.Closure property is all unrestricted in any way, for example, can be using with magnetic material Or the bar of magnetic part carries out magnetic envelope.In the option, magnetic part can be reused by Different Package bag, described Different Package bag will have the identical casings that magnetic part is kept above plane of the opening.

The presence proof for smoothing out element facilitates to slide the spoon by the free margins across the floating element in practice The open side of cup-like portion smoothes out the content in spoon or any other complicated measurer.

When needing precise measurement graininess or powdery product, user preferably uses identical apparatus or amount every time The volume of tool, the apparatus or measurer is precisely defined.Moreover, measuring the variable-volume of product (particularly, such as if necessary It is particularly the case for baby milk), the volume to be taken out depends on the milk amount to be prepared, and measurer is more multiple than simple spoon It is miscellaneous.Therefore highly useful, measurer can be taken out when user uses every time immediately.But for this purpose, user is upper one Abnormal or relatively unpleasant operation need not be executed at the end of secondary use.

Preferably, the structure of accessory device is simple, two bar is interlockable bar, preferably by semi-rigid Material is made.

In a preferred embodiment of the invention, at least one setting in arranged below is further utilized:

It is a further object to provide a kind of methods using the closed system in organ type packaging bag, to have Help the operation that food contents in packaging bag are taken out by measuring appliance.It requires, in fact, measuring appliance is user-friendly Operation.

For this purpose, the embodiment of the present invention proposes a kind of method of closed system using organ type packaging bag, envelope The system of closing includes semi-rigid accessory device, and the semi-rigid accessory device is fixed to flexible front wall and flexible rear wall, and is matched It is set to the top opening for being defined in the packaging bag on bottom opposite, this method mainly comprises the steps that

Elongated scheduled measurement utensil is provided, the height of the internal volume defined by packaging bag, measuring appliance are shorter in length than Tool has the handle free end opposite with cup-like portion,

By the way that the holding part of accessory device is connected to holding element, scheduled measuring appliance is filled fixed to accessory It sets, is preferably formed as slit after clamping, the handle free end of measuring appliance is set, holding part extends below opening completely,

Whereby, handle free end extends above the content of packaging bag, and works as packaging bag in vertical position (in the position Set, the bogey of bottom portion defining packaging bag) it is upright when obtain the storage location generally vertically of measuring appliance.

Therefore, in the next use packaging bag when, can promptly appreciate that measuring appliance, also, if handle free end is neighbouring It is open and the orientation of measuring appliance has been in vertical orientation, be then very easy to remove the measuring appliance.In other words, each In use, measuring appliance is all immediately available.

It individually or combination with the above, and it is to be understood that can be in isolation using described below every The example and details of a implementation, the present invention herein relate to a kind of organ type packaging bag, comprising:

Sack (for example, pillow formula bag orWith bottom, define the flexible sidewall extended around the longitudinal axis Antetheca and rear wall, two connectors on opposite sides between antetheca and rear wall are (in general, landing edge is parallel to the vertical of side wall Axis extends) so that sack defines the single opening on neighbouring sack top；

Closed system, including being sealed to the first bar of antetheca and being sealed to the second bar of rear wall, first Shape object and the second bar have interior mating surface, so that interlockable bar is defined, so that closed system is in enclosed construction When interlock region be attached；

It keeps opening wide device, comprising:

I) first line of deflection of a connector among neighbouring two connectors,

Ii) the Article 2 line of deflection of another connector among neighbouring two connectors, and

Iii) main flexible portion, in the first end limited by first line of deflection part and by Article 2 line of deflection Part limit second end between extend, locking device be rigidly coupled to main flexible portion first end and second end it In at least one end, and while being configured as being in enclosed construction from closed system the first obtained flat structure to Second of curved, tortuous or engagement structure pivots.

For example, passing through a kind of such packaging known to file US2014/0014789.Main flexible portion, which has, to be rigidly coupled to The first end of the main flexible portion and two opposite locking bending parts of second end, this locking bending part is It is contacted in two kinds of structures with the surface lock of complementary flexible portion.Apply light pressure device for opening, to obtain non-flat knot Structure, and when structure reaches predetermined point, at least one of which end (preferably two end) reaches latched position, keeps opening wide Structure.Closing organ only needs to apply light pressure in the outer surface for keeping opening wide the flexible portion of device, as a result, bending Part unlock is simultaneously rotated towards enclosed construction.For example, for when storing edible food, usual sealing bags in use process Open end, to extend the validity period of the surplus products wherein stored.

Product (preferably flowable food), such as cereal, milk powder or similar must be retrieved in user In the case where granulate food, it is advantageous that sack, which is positively retained at open design,.

But it in sack top flexible assembling closed system and keeps opening wide the complicated for operation of device, and actually Do not implement effectively.It is difficult that one or more belt for limiting and keeping opening wide mechanism is accurately positioned, because closed system Bar is also sealed in belt top.The locking device that entire width across open end extends is not suitable for container side wall to be maintained at Open position, at least in the open end of packaging bag in this way, to provide easy access to content.

Moreover, by this packaging, if user is fetched by apparatus (for example, with spoon along packaging bag inner surface) The content of packaging bag can occur to one tearing motion in the half part for keeping opening wide mechanism；Moreover, if institute It states one in half part not to be adequately secured on the flexible material of sack, then can change the closed state and open state of packaging bag Movement between state.This tearing motion is likely occurred, because the half part only passes through its main flexible portion rather than leads to Its end is crossed fixed in bag wall.

Furthermore it is advantageous that this packaging bag container with closed system has the option of certain user close friend.Example Such as, packaging bag container (organ type packaging bag) disclosed in file JP2013169993 has foldable portion, described foldable It is partially configured as accommodating the part of spoon.In the case where increasing this foldable portion fixed to antetheca and rear wall, system It makes also complicated.In addition, if the part for the flexible sheet material being fixed to below closed system must be by rigid material or semi-rigid Property material be made, then may reduce packaging bag container common foldability.

Here, bottom 3 can be defined by bottom wall, the bottom wall have folding line (so usually define the intermediate cross-section 14 of side wall, Intersect herein with longitudinal axis X).This bottom wall can be configured to the pedestal of packaging bag 1.It can be used and W-shaped define bottom shown in Fig. 8 A-8B Portion 3.In this non-limiting example, packaging bag 1 belongs to the classification of the reclosable packaging bag of self-supporting, so that packaging bag 1 It is suitble to show the content information of selectivity of the label on sack outer surface in a vertical position on sack outer surface.When So, different configurations can be arranged at bottom 3, and the property of can choose in side, one or more side walls are set, be preferably separated by with opening 7 Certain distance.When the side wall of two selectivity is in the case where side makes antetheca 4 and rear wall 5 is connected with each other, it should be understood that this side It encloses and belongs to flexible sidewall and define two landing edges 6a, 6b.Reinforcement pad can be set, so as to antetheca 4 and side wall it Between formed sealing, and/or between rear wall 5 and side wall formed sealing.

In certain embodiments, sack B can be single web frame of film.But in a preferred embodiment, by being assembled to Few two different pieces obtain antetheca 4, rear wall 5 and bottom 3.Here, with reference to Figure 1A -1B and Fig. 8 A-8B, by assembling three portions It is divided to (bottom wall and two flexible sides siding P1, P2, overlap each other and be sealed) to obtain sack B.

Sack B includes multiple sealing area 11a, 11b, 12a, two flexible sides sidings P1, and P2 is sealed herein, example Such as, heat-sealing.Here, plate P1 and P2 is sealed along side peripheral edge, to be respectively formed landing edge 6a, 6b, and be sealed selectively along top peripheral edge 12,12a (Fig. 8 B) is sealed to form top.Sidewall paneling The lower peripheral edge 3a and 3b of P1 and P2 can also be sealed against one another respectively, is packed with forming sealed bottom and therefore completing closing Bag structure.But in the especially preferred embodiment of the invention that Fig. 8 A and Fig. 8 B are illustrated, at least one folding line Bottom lateral coaming plate P3 is attached to the inner surface of sidewall paneling P1 and P2.These plates P1, P2 define flexible front wall and rear wall 4,5 herein. Part of the bottom lateral coaming plate P3 more than seal line is not attached to the inner surface of sidewall paneling P1 and P2, so that the centre of side wall Section 14 is free, and is extended up to inside the sack B of fold-type.

Alternatively, bottom lateral coaming plate P3 and sidewall paneling P1 and P2 can be made of identical web material.Such as Doyen human hair The United States Patent (USP) 3 of cloth disclosed in 380,646, by folding the bottom part of continuous net with W-shaped section, can form bottom Portion lateral coaming plate P3.

For more commonly, it should be appreciated that when packaging bag 1 is in opening-wide state, sack B flexible defines at least three sealed The internal volume V of side (bottom side, right side and left side), whereby, the opening 7 of the sack B opposite with bottom 3 define the list of sack B A opening 7.It is measured between bottom 3 and single opening 7, internal volume V has determining height H.Landing edge 6a and 6b can To be grown as determining height H, as shown in Figure 1A.

The thin-film material for being used to form sack B can be plastics, such as low-density, intermediate density or high density polyethylene (HDPE), Polypropylene, polyester (PET), polyamide or packaging industry commonly any other material, copolymer or its mixture.Film Material can be single layer casting or blown film, multi-layer, co-extruded or laminated film.Thin-film material can also include one layer or more Layer paper, metal foil, vacuum deposited metal or aluminium oxide or silica inorganic layer and/or polymer barrier layer, such as ethylene Vinyl alcohol or polyvinylidene chloride (or other barrier layers).Certainly, these materials and non-limiting example.

An important aspect of the invention is that material is flexible, and enables to form side wall.If film is Multilayer film, it is preferred that the internal layer of at least sack B is heat salable layer.

Referring now to Fig. 2A -2B and Fig. 8 A-8B, it is seen that closed system 2 includes two bars 8,9, and the bar exists It is fixed to one another at respective connector 6a, 6b.This bar 8,9 defines the two half-unit point of closed system 2 herein, and is set as Close to the accessory of opening 7.First bar 8 of closed system 2 is sealed to antetheca 4, and the second bar 9 is then sealed to rear wall 5.Therefore sack B internal layer is covered two bars 8 and 9 made of semi-rigid material.In general, sealing in a continuous manner Bar 8,9, to prevent leaking between sack B and bar 8,9.After having loaded content 13, add in packaging bag 1 In the case where entering inert gas, this point is particularly advantageous.

For two bars 8 and 9, this semi-rigid material (usually extrusion polymerization material) can be identical.Half Rigid material (relatively hard and flexible, optionally to have memory characteristic) can be high density polyethylene (HDPE), low-density Polyethylene, polypropylene, polystyrene, PET, Nylon^TM, in the context of the present invention feasible any other polymeric material or its Any combination." memory " word be meant that material be deformed by stress structure and eliminate cause deformation deformation force it Afterwards, material returns to its initial Sliver-Free Catalyst.

In a preferred embodiment, two opposing end portions 8a-8b, 9a-9b (see Fig. 2A -2B) sealing of two bars 8 and 9 Belonging to landing edge 6a, in 6b or two regions contradicted with landing edge 6a, 6b.The end 8a-8b, 9a-9b because This is extended to outside internal volume V, and forms the part of two landing edges 6a, 6b.

As shown in Figure 1A -1B, Fig. 2A -2B, Fig. 5, Fig. 8 A-8C and Figure 11, two bars 8 and 9 can be respectively provided with pulling Part 16 or 18, the drawing article are projected upwards from upper limb.When packaging bag 1 is in opening-wide state, which surrounds opening 7.Pass through The upper limb defines the plane of opening 7.Here, the two linear type upper limbs separated by drawing article 16 are arranged in the first bar 8 Part 81,82.In the second bar 9, it is also provided with the two linear type upper edge portions 91,92 separated by drawing article 18.In item This upper edge portion 81,82,91,92 at the top edge 8c and 9c of shape object 8 and 9 defines the plane of opening 7, such as Figure 1A and Figure 11 In it is especially high-visible.

In the first flat structure of the closed system 2 shown in Figure 1B, a pair of opposite drawing article 16,18 is selectively It is in contact with each other.After forming, filling and sealing, packaging bag 1 is assumed to be substantially flat structure and (is especially separated by with bottom 3 Certain distance).Drawing article 16,18 and two landing edge 6a, 6b are separated.Here, the drawing article defines central ear, it is high It spends similar or different.Alternatively, the top of closed system 2 can with otherness be arranged in drawing article 16,18, in opposite drawing May there are displacement and/or small interval between moving part 16,18.

It is preferred that as seen in figs. 2a-2b, the height H1 of drawing article 16,18 is roughly the same and is smaller than 15 or 20 millimeters.It draws Moving part 16,18 is rigidly coupled to the main flexible portion 28,29 of bar 8 and 9.By so set, the finger of user can be with It is validly positioned off the very close place of 7 plane of mouth, and drawing article 16,18 is prevented to be bent.It should be understood that user was not necessarily to In it is apparent firmly, can apply pressure appropriate (apply pressure outward to be open, inwardly apply pressure so as into Row sealing).

With reference to Fig. 8 A-8B, packaging bag 1 selectively has top peripheral edge 12, in order to remove packaging bag 1 this Top section and cut or torn or peeling action before, 7 will not pour out or take out in packaging bag 1 by being individually open It is tolerant.In other words, content 13 (for example, milk powder or other graininess or powdery product) is fully retained in packaging bag 1, It is used for the first time when removing top peripheral edge 12, selectively tongue is removed by one or more, tears Split tongue, weak line etc..Here, (being that linear type is empty in this non-limiting example shown in Fig. 8 B and Fig. 8 C along dotted line Line) when being enough close to content, reason is that closed system 2 is not on the first flat structure for simple cutting.Preferably, interior Tolerant 13 upper water plane 19 is extended below in closed system 2.

Certainly, dotted line may not be linear.For example, it is not necessary that flexible material is retained in corresponding drawing article 16 or 18 Left or right side, top peripheral edge 12 can be removed.

The top 120 of packaging bag 1 preferably have weak line 12b (at dotted line), the weak line cross two sides of wall 4 and 5 to Extend, it is neighbouring but to be below top periphery 12a, and in 8,9 top of bar, as described below.For example, in antetheca 4 and rear wall 5 Before being sealed, or after the two is sealed jointly, 4 He of antetheca is worn or delineated by laser or lancination Rear wall 5 is to form weak line 12b.The one or both ends of weak line 12b are preferably ended up (see Fig. 8 C) with recess 12c, thus when user beats When opening packaging bag 1, so that stress is concentrated and helps to start to tear along weak line 12b.

For more commonly, it can be set and define the restraint device of tight seal in top peripheral edge 12, so as to first Before use, reclosable closed system 2 is protected.Drawing article 16 and 18 is covered by restraint device herein.But as choosing It selects, drawing article can extend relative to thin-film material or the foil lining 21,22 for defining bag material in outside.In this case, it draws Moving part (not shown) projects radially outwardly on the top of packaging bag 1 from a part of sack B, so that this part sack B presss from both sides Between bar 8 or 9 and corresponding drawing article.

After first use, as shown in Fig. 4, Fig. 8 A and Figure 11, closed system 2 is in second of structure, due to by two Device is opened wide in the holding that bar 8 and 9 defines, so antetheca 4 and the interval of rear wall 5 are wider.

More precisely, one be sealed among the bar 8 and 9 of sack B is herein the first bar 8, comprising:

A connector among-the first scheduled line of deflection 25a, neighbouring two connector 6a, and it is not defined in strip An end 8a (for defining the associated end of connector 6a) for object 8,

Another connector among the scheduled line of deflection 25b of Article 2, neighbouring two connector 6b, and it is not defined in item An end 8b (for defining the associated end of connector 6b) for shape object 8,

Main flexible portion 28 (being specifically shown in Fig. 3-4), extends between first end 28a and second end 28b, herein by First scheduled part line of deflection 25a limits the first end, is limited herein by the scheduled part line of deflection 25b of Article 2 Second end 28b,

Opposite pivoting portions 31 and 32, including the first pivoting portions 31 and the second pivoting portions 32, described first pivots Part is connected with each other first end 28a and end 8a, and second pivoting portions 32 keep second end 28b and end 8b mutual Connection.

Two opposite pivoting portions 31 and 32 preferably have the identical bar 8 near opposing end portions 8a and 8b, with Just it is spaced in main flexible portion 28 and setting between usually harder connector 6a, 6b.In 8 in the first bar, main flexibility Therefore part 28 can be hinged to pivoting portions 31,32 at first and Article 2 line of deflection 25a and 25b, the pivoting portions are not It is attached to the second bar 9 (therefore this pivoting portions are different from two connector 6a, any one of 6b connectors).Such as Figure 11 It is shown, the thickness at connector 6a-6b be about define in main flexible portion 28 and end 8a, 8b thickness (as shown in figure 3, This is equal thickness) twice.

In the first bar 8, and selectively in the second bar 9, line of deflection 25a, 25b longitudinally extend, and It and is to cut down thickness by part to obtain.As shown in Figure 2 A, line of deflection 25a, 25b and connector 6a, the distance between 6b are reduced D usually makes it be less than or equal to 10 millimeters, preferably between 2 millimeters to 5 or 6 millimeters.With reference to Fig. 3, for example, semi-rigid material Determination thickness e 2 be equal to or less than main 28 material thickness e1 of flexible portion 50 percent.This material thickness determined E2 is preferably defined by each external slot 35,36,37,38, and the external slot 35,36,37,38 is from the top of bar 8 or 9 Edge 8c or 9c extend lengthwise into lower edge 8d or 9d.The shape of equal thickness is optionally set in the second bar 9.

As shown in Fig. 2A, Fig. 4 and Figure 11, the first end 28a and second end 28b of flexible portion 28 can be respectively provided with lock Piece 41,42, to define the locking device for keeping opening wide device.Although there are two locking plates for the tool of the first bar 8 described herein 41,42, but can also have other settings, for example, a locking member outstanding is only set in the first bar 8, and/or The locking member outstanding of one or more selectivity is formed in the second bar 9.

Each knuckle joint is set, is herein knuckle joint 44a-44b and 45a-45b spaced apart, herein material thickness office It reduces in portion.The position of first scheduled line of deflection 25a is corresponding with the aligned position of a pair of of knuckle joint 44a and 44b.Locking plate 41 are defined by notch, and hinged at its substrate 41a.Opposite locking plate 42 is also defined by notch, and at its substrate 42a Hingedly, as illustrated in figs. 2 a and 5.It should be understood that the substrate 41a or 42a of each locking plate 41,42 are herein in two knuckle joint 44a- Extend between 44b, 45a-45b.By so set, locking plate 41,42 is configured as in flat structure (closed system 2 Bar 8, in the case that 9 are fixed to one another) it is (curved in bar 8,9 as shown in Figure 1A, Fig. 4 and Figure 11 with second of structure In the case of) between pivot, second of structure is curved, tortuous or engagement structure.

The length of each locking plate 41,42 (in substrate 41a, measuring between 42a and slide outside edge) is about 2 millimeters. For more commonly, it is preferred that this length is greater than the nominal thickness e1 of the first bar 8, but is no more than in auricle 41,42 From substrate 41a, 42a be obviously bent in the case of threshold value.Preferably, the nominal thickness e1 of of length no more than first bar 8 Three times.

It should be noted that interlock region 10 is elongated, institute along imaginary axis Y in the first flat structure of closed system 2 It states imaginary axis Y to intersect with upper hinge connector 44a and 45a, and perpendicular to longitudinal axis X.

Fig. 6 is illustrated can define knuckle joint 44a-44b and 45a-45b by simple cutting operation, at first Anchoring element 51 is formed on the inner surface of shape object 8 executes the cutting operation later.Similar operation can be executed, to obtain Second bar 9, but slit 37,38 can only be defined, because it is considered that there are two locking members with regard to foot on the first bar 8 It is much of that.In a variant, each bar 8,9 all has one or more locking members, such as locking plate 41,42.

With reference to Fig. 7 as it can be seen that interior slit can be defined as one or more slits.It should also be understood that the property of can choose it is opposite In substrate 41a, 42a mobile the knuckle joint 44a-44b and 45a-45b of locking plate 41,42, as shown in fig. 6-7.It can be conducive in this way Obtain longer locking plate 41,42,141,142, without increasing line of deflection 25a, 25b and connector 6a, the distance between 6b d.Between being somebody's turn to do Every can be down to 5 millimeters, or for the first bar 8, the smaller interval.With similar line of deflection, Corresponding distance can be identical as the second bar 9.

Referring now to Fig. 4 as it can be seen that in the case where bar 89 is widened, locking plate 41,42 is curved.Drawing article 16, Starting (in the case where holding or the drawing article drawn apart from one another) makes winner's flexible portion 28,29 according to circular shape at 18 Shape is similar shape.Because of connector 6a, 6b is hard enough, and in terms of transverse plane, and adjacent pivoting portions 31,32 is very short, So there is no obvious bendings for this pivoting portions 31,32 (pivoting portions still have substantially flat shape).

It at each line of deflection 25a, 25b, is compared with connector 6a, 6b, the end 28a and 28b of main flexible portion 28 are because herein In angled structure.Because of the angle, each locking plate 41,42 is directed away from adjacent connector 6a or 6b and against Article 2 Each the contact surface CS1, CS2 of shape object 9.Contact surface CS1 and CS2 can be respectively adjacent to one among two connectors 6a, 6b Connector.In the case where main flexible portion 29 of the setting slit 37 38 to define the second bar 9, it should be appreciated that the contact surface Opposing end portions 29a, 29b extension of the CS1 and CS2 in main flexible portion 29.Such as slit 37,38 high-visible in Fig. 4, selective Being conducive to define scheduled line of deflection in the second bar 9, the line of deflection faces line of deflection 25a, 25b just, so There is also pivoting portions 31 ', 32 ' in second bar 9.

For more commonly, it should be appreciated that when closed system 2 is in second of tortuous or curved structure, as shown in figure 4, Any locking member being arranged close to pivoting portions 31,32 can be kept by such contact surface CS1, CS2.

Due to keeping opening wide device, so the open design is corresponding with predetermined structure, it is described herein to keep opening wide device It is defined by bar 8,9 and (there was only two panels plastic material in the advantageous embodiment).In fact, by such as locking plate 41, Locking member as 42 defines bistable by bar 8 and 9 and is attracted the unlimited device of holding.Because bar 8,9 is as insertion connector End 8a-8b in 6a, 6b is remote as 9a-9b extends, and for defining closed system 2, so this keep opening wide Device is firm.

According to one embodiment of present invention, packaging bag 1 includes at least one locking member or similar locking device.Such as Used herein, " locking " word and its derivative refer to through frictional force, adhesion strength or feasible in the context of the present invention Other power are maintained at the structure of appropriate location.Therefore " locking " word and its derivative can also refer to including more than one semi-rigid The engagement of the structure of property locking plate 41,42,141,142 (such as seeing Fig. 5) or similar component.

Open packaging bag 1 as shown in figure 11, it is necessary to disengage the anchoring element 51,52 of closed system 2.By simply The drawing article 16,18 on the top and/or selectivity that hold opposite wall 4,5 carries out the operation, for separated anchoring element 51,52 The pressure applied manually is enough to make the sufficiently bending of bar 8,9 (beyond angle threshold).

The case where angle between main flexible portion 28 and one or more pivoting portions 31,32 reaches predetermined threshold Under, at least one end 28a, 28b (preferably two end 28a, 28b) reach latched position, keep open design.Closing organ Slight pressure is only needed, is usually applied in the other parts of drawing article 16,18 or the bar 8,9 for defining closed system 2 Add thumb or finger pressure.The memory characteristic of strip preferably facilitates to reclose in a tightening way.

Certainly, locking member that is outstanding herein and being configured as locking plate 41,42 is rigidly coupled to corresponding first End 28a and second end 28b, and be configured as pivoting from the first flat structure to second of structure, described the first is flat Flat structure is obtained in the case where closed system 2 is in enclosed construction, second of structure be it is curved, tortuous or The structure of engagement.

Locking plate 41,42 can have the sliding edge 49 for being basically parallel to pivoting portions 31,32, thus engage the second bar 9 corresponding contact surface CS1 or CS2.Because engaging by locking plate 41,42, and because of the second bar 9 and there is locking plate 41,42 the first bar 8 is made of semi-rigid material, so main flexible portion 28 is kept (herein in bending knot Structure) in the orientation separated relative to the second bar 9.

With reference to Figure 1A, Fig. 4 and Fig. 8 A, it should be appreciated that because of being specifically directed for main flexible portion 28, so for defining interlocking The complementary anchoring element 51,52 in region 10 is still to widen.In addition, between locking plate 41,42 and corresponding contact surface CS1, CS2 Contact will lead to the equally bending of the second bar 29.For this purpose, close to the corresponding pivoting portions 31 ' of the second bar 9, 32 ' are selectively arranged slit 37,38 (Fig. 4).

As high-visible in Fig. 2A-2B and Fig. 3-4, each main flexible portion 28 and 29 is suitable for because at least in central strip Shape region reduced height and be easily bent, the intermediate strip region is in the center with grip device (drawing article 16,18) Domain and respective end 8a, 8b, 9a extend between 9b.Minimum altitude in the intermediate strip region defines main flexible portion 28, 29 height.For example, this minimum altitude is less than 20 millimeters in preferred option.

Each bar 8,9 is all fixed firmly to bag in the elongated area for being parallel to upper edge portion 81,82,91,92 Sub- material.The height of this elongated area may be less than or equal to the minimum altitude of main flexible portion 28,29.Therefore, bar 8,9 Each pivoting portions 31,32 be not attached to bag material because it extends to elongated area in the following, so that bar 8 is consolidated Surely bag material is arrived.Advantageous by so set, both following do not conflict:

On the one hand, bag material when pulling drawing article 16,18 to open organ type packaging bag 1, near opening 7 Expansion, and

On the other hand, between auricle 41,42 and the peripheral region (including pivoting portions 31,32) for surrounding auricle 41,42 Relative motion,

So auricle 41,42 can pivot and be easy (and repeatedly) from bag when opening closed system 2 every time Sub- material local displacement.

For similar reason, the pivoting portions 31 ', 32 ' of the second bar 9 are it is also preferred that be not attached to bag material.Especially It is, it be stressed that each external slot 35,36,37,38 can play the role of sufficient, specific such as figure for locking effect Shown in 3-4.

In the first flat structure of the closed system 2 shown in Figure 1B, it should be appreciated that the interior mating surface of bar 8,9 can It is generally in by two opposite connector 6a, in same longitudinal virtual plane that 6b is defined.On the contrary, in second of structure, this Kind mating surface can separate the angle substantially between about 90 degree to 180 degree relative to each other.

In the first flat structure, continuously defined by anchoring element 51,52 in sealing contact.Because of two bars 8, 9 cooperations, so that sack B can be repeatedly opened and be sealed, it should be appreciated that the characteristic re-closed is realized by anchoring element 51,52 , the anchoring element 51,52 is not made of friable material.The characteristic re-closed can be equivalent to zipper form characteristic.Such as Used herein, this statement of zipper form characteristic includes pressing off formula zipper.

In some configurations, slidingtype zipper can be used, bar 8,9 is preferably made to directly constitute the part of this zipper. Characteristic can be re-closed using many other types of, especially as shown in figures 8 a-8bType characteristic, to be formed Anchoring element 51,52.

This anchoring element 51,52 may include concave-convex fixed device, for example, the male member and second in the first bar 8 Female members in bar 9, vice versa.In first embodiment (Fig. 2A -2B and 3) and second embodiment (Fig. 5), pass through setting Continuous mating surface obtains this in sealing contact in anchoring element 51,52 and pivoting portions 31,32, at the same time from this anchor Gu stripped terminal end 8a, 8b in element 51,52.Therefore, the longitudinal sealing between end 8a and 8b does not interfere interlock region 10.

The bar 108 of second embodiment is fundamentally different from the bar 8 of first embodiment, because being provided with additional Locking plate 141 and 142, as shown in Figure 5.Settable three knuckle joints, to define line of deflection 25a, 25b.As it can be seen that can be two A top locking plate 41 and 42 is cut, and orients it in opposite directions in the first flat structure.Equally, under two Portion's locking plate 141 and 142 is cut, and orients it in opposite directions in the first flat structure.

In third embodiment shown in Fig. 6, closed system 2 can have pivoting portions 31,32, and the pivoting portions are not Including any anchoring element 51,52, so that interlock region 10 is than the connector 6a, 6b in the enclosed construction of closed system 2 Between the distance L6 that measures it is shorter.In fact, interlock region 10 is provided only in main flexible portion 28.Because of pivoting portions 31, 32,37,38 can be shorter part, the no substantive difference of orientation of the shorter part in second of open design, so Closed system 2 is still enough to seal the entrance of content 13.Especially, bar 8,9 is sufficiently secured within the first flat structure In, enter internal volume V to prevent insect.

In order to which with good barrier action (especially damp proof insulation), first embodiment and second embodiment are preferred.? In the 4th Fig. 8 C specifically shown embodiment, anchoring element 51 (being herein the form of belt) is in the entire width of packaging bag 1 Or almost extend on entire width.For example, the end 8b (the end 9a for being sealed to bar 9) of bar 308 further includes anchor Gu the marginal portion of element 51.When closing closed system 2 manually by user, this structure is enough that there is good barrier to make With.Certainly, this set of anchoring element 51,52 can also be used in the other embodiments.

With reference to Figure 12, it is shown that the bar 108 of the 5th embodiment, the first bar 408 and second embodiment is very It is similar, but anchoring element 51 extends between top locking plate 41,42 and lower part locking plate 141,142.The embodiment is conducive to have There is firm holding to open wide device, and when holding drawing article 16,18, provides more skies to finger above interlock region 10 Between.Certainly, the second bar (not shown) has corresponding anchoring element 52 and two flexible portions (one in interlock region 10 tops, another is below interlock region 10), to form the opposed contact surfaces engaged by locking plate.

It should be understood that preferably there is height to be lower than end 8a-8b, the strip of one or more interludes of 9a-9b height Object 8,9.As shown in Fig. 2A -2B, Fig. 5 and Figure 11, quantity of plastics can be saved, at the same time, has firm in end 8a, 8b, 9a, 9b Connector because height it is higher.In this preferred embodiment, about at least one bar 8 and 9, height is (herein from top The straight edge sections 81,82,91,92 of edge 8c or 9c measure) increase with increasing with the space of drawing article 16 or 18.

It should also be understood that in the case where reduced height, for example, highly down to 6 millimeters or lower (minimum altitudes, with end 8a, 8b, 9a, 9b are separated by a distance), main flexible portion 28,29 is easier to be bent.It should be noted that anchoring element 51,52 can be used as The reinforcing element of corresponding bar 8 or 9.

Anchoring element 51,52 can be integrally formed with bar 8,9 and (utilize identical plastic material) or and bar 8,9 co-extrusion pressures or post forming.In the case where not using identical material, for example, anchoring element 51,52 is by flexible material system At the modulus of the flexible material, which is lower than, defines flexible portion 28,29, pivoting portions 31,32,31 ', 32 ' and end 8a-8b, 9a- Strip used in 9b.

When closed system 2 is in closed state, as shown in Figure 15 and Figure 16, the plane in the first bar 8 of locking plate 41,42 Extend, but is independently pivoted relative to antetheca 4.Here, in preferred embodiment as shown in figure 15, the first bar 8 packet It includes continuous sealing and (also sees figure to the first outer surface s1 of antetheca 4 and at least one second outer surface s2 of unsealing to antetheca 4 8A).This second outer surface s2 has locking device (being defined herein by locking plate 41,42).Locking plate 41,42 is therefore close to (still Not being abutted in preferred option) bar 8 is attached to the part of antetheca 4, and at the same time can be with:

When being handled by user, the mass motion of the first bar 8 is accurately followed；And

Each line of deflection 25a and 25b in complete open design are pivoted, because the antetheca 4 of sack B does not keep locking Piece 41,42.

Although it is neat with the inner surface of bar 8,108,208,308 to have illustrated each locking plate 41,42,141,142 Flat, closed system 2 can have at least one auricle 41,42, and the auricle exceeds thickness in the enclosed construction of closed system 2 E4, as the embodiment of Figure 19-20.Because exceeding E4, locking plate 42 defines protrusion part BP, the protrusion split-phase pair It is prominent in outside in the outer surface of corresponding bar 8.In general, this point is also applied for locking plate 41.

Additionally or as selection, when closed system 2 is in open design, an auricle 42 of bar 8 is engageable In the recess 39 of bar 9.In general, in 9 curved situations, shoulder 39a (Figure 20), which is defined, accommodates locking plate 42 in bar 8 The surface (such as Figure 1A and 4) of sliding edge.Here, the protrusion part BP of locking plate 42 is higher than width, the height and auricle of shoulder 39a This of 42 is a part of identical, this is conducive to make the length long enough of the contact between shoulder 39a and locking plate 42.

The notch 48a and 48b that longitudinally extend for being parallel to bar 8,9 define the top and bottom end of locking plate 42.It is this to cut Mouth 48a, 48b can be longer than the width of protrusion part BP.As a result, line of deflection 25b is separated by centainly with having the part beyond thickness E 4 Distance extends.This is conducive to keep flexibility along the line of deflection 25b at substrate 42a.The foil of sack B serves as a contrast 21 (as shown in figure 11) It is contacted in the non-adhering zone of foil lining 21 with protrusion part BP, therefore in the curved situation of bar 8, does not influence auricle 42 Bending.Sack foil lining 21 is at least fixedly attached to bar 8 above auricle 42 and in side connector 6a.

In the embodiment shown in Figure 19-20, for example, bar 8,9 can be obtained by injection molding.It is convex for more commonly Out or the region of thickening helps to increase by the tension and angle of 2 open design of closed system.Certainly, this that there is protrusion or thicken The structure in region may be selectively applied to define all or part of auricles in bar 108,208,308, such as Fig. 5, Fig. 6 With shown in Fig. 8 C.

In Figure 19, closed system 2 can have any kind of anchoring element 51,52, preferably have completely in latch ear The elongated anchoring element 51,52 extended above piece.

In a preferred embodiment, each auricle 41,42,141,142 is hinged all at substrate 41a, 42a, 141a, 142a, The substrate 41a, 42a, 141a, 142a define determining height h2, and the height of the determination is less than associated flexural line 25a, 25b The half of the height H8 of the bar 8,9 at place.Following relationship: h2/H8≤2/5 can be met.Determining height h2 can be greater than or wait In 4 or 5 millimeters.In the case where shoulder 39a is arranged will pass through the engagement of auricle 42, this shoulder 39a is and lower edge 8d phase It defines at a certain distance, and can have identical height (height h2) with the substrate 42a of auricle 42.

Bar 8,9 is pierced through in separated region, to define slit 35,36,37,38, it is seen that each bar 8,9 Thickness e 1 is all relatively large, for example, being greater than or equal to 1 millimeter.Because defining bar 8,9 using semi-rigid material, so anchoring Element 51,52 is usually elongated and sufficiently flexible.

With reference to Figure 16, it is another can be greater than (being herein four elements 51) for the quantity of anchoring element 51,52 in a bar 8 The quantity (being herein three elements 52) of anchoring element 52 in a bar 9.Here, anchoring element 51,52 is by bar 8,9 Each inner surface on mushroom-shaped valve rod define.When two inner surface cooperations, this mushroom-shaped valve rod, which can provide, effectively to be stung It closes (being likely to be the occlusion heard).It is so engaged in the relatively thin outer edge of each head 54 of mushroom-shaped valve rod 53.Phase Coincidence distance D1 between enemy 54 can only be about 1 millimeter, to be easier to separate bar 8,9.

For more commonly, be conducive to obtain compared with low-ratio D1:e1, for example, being less than or equal to 1:5.In this way to locking member The changing firmness requirements of part 41,42 and extraordinary compromise is realized between the flexibility demand of interlock region.Anchoring element 51,52 Stem portion 53 extends in parallel, and has equal length D3, and the length can be greater than the dimension D 2 of head 54 (according to stem portion The dimension D 2 of the same direction measurement longitudinally extended).Between the bar 8,9 in the region of neighbouring anchoring element 51,52 Interval D 4 can be equal to nominal thickness e1, for example, being herein about 1 millimeter.Certainly, other shapes can be used for anchoring element 51,52, Supplement replaces illustrated shape.In some instances, certain mushroom-shaped valve rods can be replaced with tip.

With reference to Figure 17 and Figure 18 A-18F, it is seen that certain options, wherein being to pass through injection molding by the accessory that bar 8,9 defines It obtains.It should be understood that the shape of anchoring element 51,52 can be different.In total Options, anchoring element 51,52 all with ear Piece 41,42 extensions separated by a distance, the auricle are separately positioned in first end 28a and second end 28b.

The method of manufacture packaging bag 1 can be especially executed in the following way.It conventionally produces herein by two The wall for the sack B that the side enclosure wall P3 (see Fig. 8 A-8B) of a opposite plate P1 and P2 and selectivity are defined.The flexible material of sack B Material may include plastics, and preferably multilayer compound, such as in the case that product is milk powder, the multilayer compound is formed Very effective oxygen barrier layer.Of course, it is possible to pass through other materials, especially metal or composite material (one or more multi-layer boards Certain parts of sack B can also at least be constituted) production sack B.

With reference to Figure 13, is produced using extruder 60 and forming roller 62 by polyolefine material, preferably given birth to respectively by PP Produce 8,108,208,308,408 and the second bar 9 of the first bar.The bucket of extruder 60 or similar section melt, and force molten Melt plastics 20 and drawing-in point 64 is entered by mold 61.More precisely, molten plastic 20 (also referred to as molten resin) is continuously drawn Enter in the gap along the peripheral surface formation of rotational forming roller 62, so that plastics surround type roller surface outside forms strip At least part strip-form base of object 8,108,208,308,408 or 9, and it is filled in the lock chamber battle array defined in rotating roller 62 Column, to form some parts of fastener/anchoring element 51,52, as the protrusion extended from the side of sheet form base. Here, the continuous band of molten plastic 20 can be narrow as a bar 8 or 9, also, before the cutting stage, such as the top Fig. 6 Shown in portion, anchoring element 51 can be formed.Cavity in roller 62 usually has certain shapes, is suitble to engagement ring to be formed Anchoring element 51.In the case where anchoring element 51 52 forms zip closure, cavity can be replaced by one or more grooves, For anticipated shape relative to anchoring element 51,52, the groove has complementary profile (constant profile).

Substrate roll 63 is used, in a conventional manner so that when molding anchoring element 51 or 52, there is sufficient pressure.This Kind structure is particularly suitable for defining hook-type anchoring element 51 in the first bar 8.Can be had in the conventional mode Second bar 9 of ring or similar anchoring element 52, second bar also make to the property of can choose materials at two layers (base Bottom is with the layer for forming ring) it combines.Alternatively, ring is not necessarily the ring being closed completely and can set It is set to the female hook with significant curvature, it is more flexible than convex hook.

For more commonly, it should be appreciated that anchoring element 51,52 can have diversified fastener (for example, hook and ring-type Object) or have continuous fastener (for example, pressing zipper etc.).

Bar 8,108,208,308,408,9 with anchoring element 51,52 is by that can surround roller after drawing-in point 61 It 62 periphery and selectively advances around stripper roll 67, the stripper roll 67 assists to pull bar 8 or 9 and from roller Each embossed section is extracted in 62 respective cavities, and arrives ending equipment therefrom, is not shown.

At least for the first bar 8,108,208,308,408, cutting step is executed by cutter device 65,66 Suddenly, herein for roller 67 cutter device downstream.In fact, must cut tight after being operated by roller 62 Then the section S8 of the continuous band obtained, to obtain:

Locking plate 41,42,141,142 or similar locking device；

Slit 35,35,37,38；

Selectively, the contoured at top edge 8c, 9c preferably makes drawing article 16 or 18 be located at intermediate cross-section；

Selectively, the contoured at lower edge 8d, 9d, preferably with 8,9 end 8a of bar, 8b, 9a, 9b Place separated by a distance removes plastic material, it is also an option that property define the holding part 55 of measuring appliance 100 and/or smooth out The free margins 56 of element.

Cutter device may include one or more modules 65,66.Here, precut locking device, and cut using longitudinal It cuts and obtains the locking device with transverse cuts.Therefore cutter device is suitble to be separated by relatively short distance with bar end 8a, 8b Place executes cutting, as shown in the non-limiting example of Fig. 6.One or more locking plates 41,42,141,142 or similar locking member It is to be formed in strip, and protrusion can be formed in second of structure.(slit is not defined using cutting module 35,36,37,38) the certain parts cut can make its reduction (for example, forming anchoring element by any device appropriate By forming recess when 51,52).

First bar, 8,108,208,308,408 and the second bar 9 is cut from continuously extruded take respectively, excellent Choosing defines closed system 2 using identical polyolefine material.

At least one bar 8 is obtained to the property of can choose by combining the extruding plastic material more than one layer, 108,208,308,408,9.For example, sheet form base can be used as the bracket of the outer layer with anchoring element 51,52.Certainly, if Outer layer is provided, this outer layer becomes bar 8 then for good and all in conjunction with the molten plastic of basal layer, and 108,208,308, A part (when resin solidification) of 408 or 9 strip-form base, so that two layers on final bar cannot be distinguished.

After the cooling step, it should be appreciated that the semi-rigid plastics material of continuous band has memory characteristic, and is usually hard , for example, pictureIt is equally hard, and plastic material unlikeIt is frangible like that (preferably, modulus of elasticity is greater than 1GPa).Polypropylene, polyethylene (HDPE, LDPE) and similar material (including PEF) can be used, because in line of deflection 25a, 25b The loose-joint butt intensity that place defines is stronger, and locking plate 41,42,141,142 is hard enough.

It is preferred that the (not shown) after length of the final cutting to define bar 8,108,208,308,408 or 9, is fetched Bar 8,108,208,308,408,9 with anchoring element 51,52.Then make these bars 8,108,208,308, 408,9 combine with 4 inner surface of antetheca or 5 inner surface of rear wall respectively.

Of course, it is possible to by with a piece of plastic material (its landing edge is intersected with the virtual positive middle section of sheet material) while obtaining 8,108,208,308, the 408 and the second bar 9e of the first bar of the same closed system 2.In this case, can have Folding step is executed, sharply to obtain the enclosed construction of closed system 2.Then execute it is longitudinally cutting, so as to by longitudinally connecing 8,108,208,308,408 and the second bar 9 of the first bar is separated at the lower edge that head defines.It is adjacent in extruding two When bar, initially slit can be set in joint.This facilitates the closing in the previous dynasty closed system 2 for being attached to sack B Structure carries out folding operation.

Fig. 8 C and Figure 12 show the exemplary position of the first bar 308,408, and end (only shows end herein 8b) block the edge bond area 30 of antetheca 4.This edge bond area 30 is for defining connector 6b (in antetheca 4 and rear wall 5 Between fasten during bond area is operated).Preferably, bar 8,108 can be placed in this manner, 208,308,408,9 each end 8a, 8b, 9a, 9b, so that these bars are inserted partially into connector 6a, in 6b.

Before loading step, connector 6a is obtained by the first sealing step, 6b (can be in bottom 3 and top periphery side Edge 12 extends beyond being open between 7 other appropriate ends) and at least one lower seal.In some configurations, bottom Peripheral edge 3a and 3b traverse landing edge 6a, and 6b extends, and the intersection punishment between connector 6a, 6b and edge 3a, 3b Two lower comer parts CP1, CP2 are not defined.After the filling step that internally volume V loads content 13, by the Two sealing steps define the top sealing 12a at top 120.

In some embodiments it is possible to additional box usually harder than sack B be arranged, to encapsulate one or more Packaging bag 1.Although embodiment shown in each figure shows the edge bond area 30 of rectangle, however, it is understood that according to be produced Packaging bag 1 type, other shapes can be used.In addition, certain steps can be executed in the earlier or later stage, such as One or many cutting steps.Therefore, knuckle joint 44a, 44b, 45a, 45b are not necessarily by molding anchoring element 51, What the cutting operation executed after 52 (or being similarly shaped) was formed.

In some configurations, can be utilized by cross cutting or directly Shooting Technique or laser engraving and it is other can The technology of energy forms knuckle joint 44a, 44b, 45a, 45b.In some configurations, the material of knuckle joint 44a, 44b, 45a, 45b Material thickness can be 10 or less of the material thickness of adjacent locking plate 41,42 and adjacent pivoting portions 31,32.At certain In a little structures, the material thickness of knuckle joint 44a, 44b, 45a, 45b are about 0.2 millimeter and about 0.5 millimeter.

In some configurations, by independent material and/or multi-piece type linkage, (it is coupled in main flexible portion 28 or 29 Between each locking plate 41,42,141,142) knuckle joint 44a, 44b, 45a, 45b are provided.However, it is possible to as that can roll over Folded, bending or any part pivoted provide knuckle joint 44a, 44b, 45a, 45b.For example, can only pass through the folding in material Knuckle joint 44a, 44b, 45a, 45b is arranged in trace or crease.

The closed system 2 for the accessory being suitable as in packaging bag 1 is illustrated now, with reference to Fig. 2A -2B, Fig. 5, figure 8C, Fig. 9 A-9C and Figure 10-11, Figure 14, this closed system tool interact there are two bar and with measuring appliance 100 Ligule contact portion 55,55 '.

Closed system 2 can have above-described all features.But it keeps opening wide device and/or realizes interlock region 10 concrete mode is considered as options.For terseness and simplicity, sack B is not repeated, because the wall of sack B can be with The declaratives of front are identical.But when being related to following part and illustrating, closed system 2 is connected to the mode on the top sack B It is not restricted to previous examples.

It is similar to the spoon in illustrated embodiment about the measuring appliance 100 that Fig. 9 A and Figure 11 are illustrated, in other words, institute Measuring appliance is stated with cup-like portion 101, the cup-like portion defines fixed measurement volume, and in the options, institute Cup-like portion is stated until 101 open side of cup-like portion is substantial cylindrical.Handle 102 extends to certainly from cup-like portion 101 By holding 102a.Measurer 100 is therefore elongated in shape, and is made of plastic material or equivalent material.Measuring appliance 100 is predetermined form Measurer, be preferably designed to sell together with entire packaging bag 1, and its fixation measuring volume be exclusively used in being discussed it is interior Tolerant 13, it is herein food.

In the case where selling together with packaging bag 1, measuring appliance can initially be wrapped in the sack shown in Fig. 9 a, in inside In volume V or in the separate housing defined by top 120 or in the sack being secured on the outer surface sack B.

Using scheduled measuring appliance 100 enable coupling with one among bar 8 and 9 is integrally formed contacts The free margins 56 of part 55, the bar 8 and 9 is to be configured to be, so that it is tightly engaged with corresponding portion, phase described herein It should be partially the rear slit 103 and/or ring edge 14 of the cup-like portion 101 of measuring appliance 100, the measuring appliance 100 has There is known and accurate geometry.

Referring now to Fig. 2A -2B and 11 as it can be seen that each bar 8,9 can have ligule (can certainly use other shapes Shape) contact portion 55, so as to measuring appliance 100 interact, operate the bar directly or indirectly to close opening 7.Contact portion 55 is disposed entirely within 10 lower section of interlock region, and defines floating element, and the floating element does not fasten directly To the inner surface of sack B.At this as it can be seen that contact portion 55 can have recess or centre bore 50 in Figure 11.Two arm portions 40a, 40b extend downwardly into the insertion portion with linear type free margins 56 from the base part 55a of neighbouring interlock region 10 55b.Insertion portion 55b is configured to slide into inside rear slit 103, and because of the clamping action at handle 102, is led to It crosses contact portion 55 and keeps measuring appliance 100.

Because contact portion 55 is defined as downward projection of lower extension portion, the movement of connection handle 102 is Of short duration moves upwards.Contact portion 55 is made of strip, usually with the first bar 8,108,208,308,408 and Article 2 Shape object 9 is equally thin.The opposite face defined by contact portion 55 removes all reliefs respectively.Therefore, will not assemble on a surface Powder, this is conducive to correctly connect insertion portion 55b by slit 103.Alternatively, it can be formed with an opposite face wherein Certain protrusions, for example, during being inserted into the insertion portion 55b guide handle 102 movement.This selective dashes forward Part can be centered around the distribution of the contact area between handle 102 and insertion portion 55b out.

With reference to Fig. 9 B-9C, rear slit 103 can be defined in the major part and at least one clamping element 106 of handle 102, Between 107, the clamping element longitudinally extends between coupling part 106a, 107a and free end 106b, 107b.Slit 103 exists This is laterally delimited not by left side wall and right side wall, to help to be inserted into the insertion portion 55b.Contact portion 55 It can be attached to corresponding bar 8；The contact portion outstanding of 9 edge 8d or 9d.In sack B inner surface and contact portion Gap is defined between 55, to be smoothed out using free margins 56.

About rear slit 103, the mode for not being able to narrow sense understands that " rear " word (not necessarily positions in measuring appliance 100 Later).It mean onlys that the free end 102 or proximate to it of measuring appliance 100 is arranged in slit 103.Shown in Fig. 9 D In preferred embodiment, measuring appliance 100 can have simple structure, and the structure has slit 103 and setting towards open front In the slotted inlets with 101 open side the same side of cup-like portion.By the available this structure of single longitudinal cut, generally Or it is substantially same wide with handle 102.Since (but the notch can be obviously shorter than clip element 110, so as to the company of raising for notch Connect the intensity of clip element 10) and define the clip element 110 defined herein by single resilient tongue.Pass through this seed type Rear slit 103, in rear slit 103 in the case where engaged contact portions 55, hole 50 is needed to define the logical of clip element 110 Road.

The structure of clip element 110 can be similar to the clip of the cap of a pen, can be by user the insertion of contact portion 55 Part 55b is engaged in slit 103, it is not necessary that finger is placed below contact portion 55.In fact, when storage measuring appliance 100, User only touches free end 102a.

As shown in Figure 10, pass through the opening of the cup-like portion 101 relative to the sliding measuring appliance 100 of linear type free margins 56 Thus side obtains the product of certain volume to be smoothed out in measuring appliance 100, the volume very accurately with cupule Divide 101 volume corresponding.For this purpose, the length of the straight parts of free margins 56 opening at least equal to cup-like portion 101 Mouth side.In addition, if without straight parts, for example, then cannot accurately be smeared if there is spill free margins on open side top Flat powder, what is worse, in the case where convex free margins, local projecting edge may tangle cup-like portion 101 and cause Powder is poured out.On the other hand, it is necessary to be sufficiently spaced from free margins 56 and the bag sidewalls of sack B so that user without Measurer 100 need to be nearly vertically tilted, the inclination can be such that a part of product falls, and therefore cause measurement inaccurate.Because into When row smoothes out, sack B material BM is flexible and will not hinder cup-like portion 101, so obtaining gap herein.Sack B's Ring enables to be partially formed angle, θ behind contact portion 55, moreover, therefore can be relative to the material BM of sack B Radially spaced apart free margins 56 keeps base part 55a along sheet material BM at the same time.

In the case where contact portion 55 defines and smoothes out element, it should be appreciated that tongue, the tongue can be configured as It will not obviously be bent, moreover, generally can not fold (without crack or fracture).In the non-limiting embodiment, because Formed have contact portion 55 bar 8 or 9 semi-rigid material memory effect, so contact portion can be parallel to by The plane that interlock region 10 in 2 enclosed construction of closed system is defined extends, even if repeatedly smoothing out operation and repeatedly closing packet It is also such after pack 1.

With reference to Fig. 2A -2B as it can be seen that the extension L5 of contact portion outstanding 55 is lower than end 8a, 8b, the 9a of bar, The height of 9b.For example, preferably smaller than 15 millimeters of this extension by a small margin is conducive in content 13 less than 20 millimeters Floating is effectively performed above upper water plane 19, at the same time to the fully filling product of packaging bag 1.

Here, contact portion 55, which defines, smoothes out element and insertion edge, to keep the free end 102a of handle 102. As shown in figure 11, the length of measuring appliance 100 is shorter than the height H of the determination of internal volume V.

In order to keep measuring appliance 100 fixed in the case where handle 102 has been engaged in insertion portion 55b, In the case that insertion portion 55b is in the engaging structure in rear slit 103, one or more pressing pieces 59 or similar fastener can Directly to engage insertion portion 55b.These elements 59 are arranged in herein on the inner surface of clamping element 106,107.Therefore slit 103 Clamping action close to free end 102a enhances, in the case where element 59 is engaged in centre bore 50 or similar recess, this Point is especially advantageous.For more commonly, it may be provided around clip functions in 102 free end 102a of handle, to keep being inserted into Part 55b.

After amount needed for taking out, user is attached measuring appliance by engaged contact portions 55 in slit 103 100, so that contact portion 55 subsequently forms holding part.In organ type packaging bag 1, between connector 6a, 6b just The largest interval between 2 two bars of closed system is defined in middle face.Therefore, be conducive to make contact portion 55 and this virtually just Middle face P5 intersects (Fig. 8 C and Figure 12 show this mesion P5).

In advantageously reducing bar 8 or 9 in certain options of amount of plastic, length (its larger ruler of contact portion 55 It is very little) usually strictly it is lower than the one third of 10 length of interlock region, the preferably shorter than a quarter of 10 length of interlock region.Excellent It selects in embodiment, the length of the contact portion 55 measured at connector 55a can be strictly less than 50 millimeters, and free margins 56 is straight Line style continuous part is usually between 15 millimeters to 40 millimeters.

The open side of cup-like portion 101 is oriented towards bottom 3.Then measuring appliance 100 is held in place, here In lengthwise position, and by mutually fastening bar 8,9 or closing packaging bag 1 using any closed system 2 appropriate Later, keep it fixed in the position, the closed system 2 is suitble to such flexible package.If in the closed state effectively Packaging bag 1 is operated, can be enough to prevent measuring appliance 100 from falling into content 13 by insertion portion 55b fixation measuring utensil 100 In.

When next time uses packaging bag 1, measuring appliance 100 is immediately visible, and if 102 adjacent openings 7 of handle and survey Measuring device tool 100 has been in vertical orientation, then is easy to take out measuring appliance.

It is, of course, also possible to the content of packaging bag 1 is taken out by standard teaspoon or table spoon, but this will not be able to user friend Spoon is kept well, and can lose the advantage of the longitudinal storage location of measuring appliance 100.

In certain options, the contact portion 55 formed on the first bar 8 or 9 can form certain shapes, so as to Only as keeping the holding meanss of scheduled measuring appliance 100, or ligule can be smoothed out element and be arranged at another On shape object 8 or 9, or floating element is not provided.In other options, slit 103 after being not provided in measuring appliance 100, And neighbouring free end 102a forms hook-shaped protrusion, enables to be engaged on centre bore 50 in protrusion or by packing In the case where in a similar recess defined among the bar 8,9 of bag 1, measuring appliance 100 is maintained at identical vertical To storage location (general location is identical as Figure 11).

In an option, ligule contact portion 55 be set as being secured under interlock region bar 8,9 it In one individual component.For example, when encapsulating measuring appliance 100 for the first time, it can be this tongue packet in the same sack In.

Referring now to Figure 14, as it can be seen that contact portion 55 ' outstanding can also have, there are two tongues, and the tongue is by narrow Slot 75 separates, and is integrally formed with main flexible portion 28.It, can be by the end 102a of handle 102 in measuring appliance 100 At least one section or similar groove replace slit 103, for example, sliding by two opposite side grooves and/or one or more Dynamic protrusion 103a, 103b (herein by rib shape protrusion) are replaced.This protrusion 103a, 103b can be used for it is narrow 75 edge mate of slot.When placing and storing measuring appliance 100, each protrusion for being contacted first with contact portion 55 ' The front end of 103a or 103b can have small rib R1, and R2 or the similar of the wider rear end Elastic Meshing in part in slit 75 are floated It is convex.Therefore it is provided in this option and slides into cooperation.Of course it is possible to use one or more as illustrated in the embodiment of figure 9 c is pressed Casting die 59 forms occlusion in the end for placing handle 102.

Herein selectively provide two holes 50, so as to need to open the package 1 when, it is curved to facilitate main flexible portion 8 It is bent.Two free margins 56a, 56b for allowing for smoothing out are shown in Figure 14, it can with relatively narrow Both tongue portion Or such larger-size free margins 56a is fully replaced, 56b is (in its straight parts and most of aforementioned other embodiments As).

It should be noted that in this case, according to an identical mode among bar, formed by squeezing plastics Smooth out element, so that geometry is more accurate.Making the geometry of measuring appliance 100 in this way has good adaptability, Especially, if the measuring appliance and do not have well-known predetermined form, it is even more so.

Certainly, above-described embodiment is by no means limitative, and feature can combine, further, it is contemplated that other variants.Especially It is that other types of fixation can be formed in closed system 2, not necessarily passes through interlock region as shown in the drawings 10 form.For example, as supplementary features or replacing characteristic, at least one drawing article 16,18 can have fixing element, so as to handle Closed system 2 is maintained at the first flat structure.

In certain embodiments, the type of closed system 2 can be different, such as in the feelings of only contact portion 55,55 ' Under condition, remove two locking plates 41,42 (with or without the equivalent feature for keeping open package bag 1).

Term as " rear " and " preceding " is used only to be for illustrative purposes, to define the main flexible board of sack B Relative position.However, it should be understood that these terms be it is opposite, based on context, term " rear " and " preceding " can overturn.Cause This, it should be understood that wall 5 can be described as " antetheca ", and wall 4 can be described as " rear wall ".
