Description
Technical field
The present invention relates to a kind of flexible plasticity packaging that can be sealed again, the food (example that storage may be suitble to take out from the package
Such as, granular edible product uses the predetermined apparatus as measurer).More particularly, it relates to arrive a kind of organ type
Packaging bag, including：
- sack (for example, pillow formula bag or), there is bottom, define the flexible side wall around longitudinal axis extension
Antetheca and rear wall, the opposite side between antetheca and rear wall on two connectors (in general, landing edge is parallel to side wall
The longitudinal 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 as to define interlockable bar, so that closed system is in enclosed construction
When interlock region be attached；
- keep opening wide device, including：
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 be configured as from closed system be in enclosed construction when the first obtained flat structure to
Second of curved, tortuous or engagement structure pivots.
Background technology
For example, pass 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 the two of second end opposite locking bent portions, this locking bent portion is the
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 that the outer surface for the flexible portion for opening wide device is being kept to apply light pressure, the result is that bending
Part unlock is simultaneously rotated towards enclosed construction.For example, when being used to store edible food, usual sealing bags during use
Openend, to extend the term of validity 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 of granulate food, it is advantageous that sack, which is positively retained at open design,.
But in flexible sack top assembling closed system and keep opening wide the complicated for operation of device, and actually
Do not implement effectively.It is difficult to 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 openend extends is not suitable for container side wall to be maintained at
Open position, at least in the openend of packaging bag in this way, to provide easy access to content.Therefore, using US2014/0014789
Shown packaging bag (have be considered as hand-made keep opening wide device), by Reusability/operate repeatedly closed system
Afterwards, holding can not be made to open wide device and still maintain efficient.This is because the efficiency of too difficult accumulation closed system and holding are spacious
The efficiency of opening apparatus.
File US2014314342 shows another accessory that mechanical lock is provided using the hinge of a pair of of bar.It keeps
Device is opened wide to be defined by the bar extended above the bar of closed system.By this positioning, user can be straight
It connects operation to keep opening wide device, this helps to repeat efficiency.This operation for keeping opening wide device is not considered user friendly
's.
In the case of mass production, US5,174,658, which disclose the holding defined by the bar of closed system, opens wide
Device.Two bars are made of the relatively stiff elastic material with memory function, for example nylon or high density are gathered
Ethylene.A pair of of bar is formed so that when in unstressed structure, the bar is circular or oval.
Therefore, when sack is opened, almost circular opening is easily formed, to help to be packed into or pour out the content of sack
Object.In this case, it is complete so as to locked package bag between two bars of closed system without specific mechanical engagement
Full opening-wide state.Although this system provides the open feature of holding for being suitble to Reusability, it is considered as it and manufactures cost
It is higher (usually around arch mandrel or cylinder molding bar, with free bow-shaped structural and to have pressure
Flat structure).In addition, the usually preferred bare mechanical lock of user, because user is more easily implemented " locked in " operation.
, it is necessary to which a kind of closed system of user-friendly organ type packaging bag simple in structure, includes for more commonly
The mechanical lock of efficiency for the complete opening-wide state of locked package bag, while meets the method for mass production.
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 keeping opening wide the tearing motion of one in the half part of mechanism；If moreover, 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 by its main flexible portion rather than is led to
Its end is crossed fixed in bag wall.
Furthermore it is advantageous that this option of the packaging bag container with certain user close friend with closed system.Example
Such as, the packaging bag container disclosed in file JP2013169993 (organ type packaging bag) 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 fixed to the flexible sheet material below closed system must be by rigid material or half just
Property material be made, then may reduce packaging bag container common foldability.
The content of the invention
Therefore, it is an object of the invention to propose a kind of packaging bag container, especially organ type packaging bag, due to manufacture
It is simple for process, so user-friendly characteristic is presented, and it is equally firm at least as conventional organ type packaging bag.
For this purpose, the purpose of the present invention is a kind of organ type packaging bag of the above-mentioned type, wherein, main flexible portion and
At least one locking member of locking device is defined by the first bar, and first bar is semi-rigid by what is determined
Made of plastic material, moreover, wherein, made of semi-rigid plastics material (preferably also by definite semi-rigid plastics material)

For more commonly, the restraint device that top peripheral edge 12 defines tight seal can be arranged on, 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 compared with thin-film material or the paper tinsel lining 21,22 for defining bag material in outside.In this case, draw
A part of the moving part (not shown) in the top of packaging bag 1 from sack B projects radially outwardly, so that this part of 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, thus antetheca 4 and rear wall 5 be spaced it is wider.
More precisely, one be sealed among the bar 8 and 9 of sack B is herein the first bar 8, has：
A connector among-the first predetermined line of deflection 25a, neighbouring two connector 6a, and strip is not defined in
An end 8a (for defining the associated end of connector 6a) for object 8,
Another connector among the predetermined line of deflection 25b of-Article 2, neighbouring two connector 6b, and item is not defined in
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 predetermined line of deflection 25a part limits the first end, is limited herein by the predetermined line of deflection 25b parts 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 make 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 set and be spaced between main flexible portion 28 and usually harder connector 6a, 6b.In 8 in the first bar, main flexibility
Therefore part 28 can be hinged to pivoting portions 31,32 in first and Article 2 line of deflection 25a and 25b, the pivoting portions are not
It is attached to the second bar 9 (this pivoting portions are therefore different from any one connector in two connectors 6a, 6b).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 Longitudinal extending, and
And it is obtained by local thickness of cutting down.As shown in Figure 2 A, the distance between line of deflection 25a, 25b and connector 6a, 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 figure 3, for example, semi-rigid material
Definite thickness e 2 be equal to or less than main 28 material thickness e1 of flexible portion 50 percent.This definite material thickness
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, only set in the first bar 8 a prominent locking member and/or
The locking member of the protrusion 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 predetermined 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
It is hinged, as illustrated in figs. 2 a and 5.It is to 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.It sets by doing so, 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, being measured between 42a and slide outside edge) is about 2 millimeters.
For more commonly, it is preferred that this length is more than the nominal thickness e1 of the first bar 8, but is no more than in auricle 41,42
From substrate 41a, the threshold value in the case of the apparent bendings of 42a.Preferably, the nominal thickness e1 of of length no more than first bar 8
Three times.
It should be noted that in the first flat structure of closed system 2, interlock region 10 is elongated, institute along imaginary axis Y
Imaginary axis Y is stated with upper hinge connector 44a and 45a to intersect, 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 and performs the cutting operation afterwards.Similar operation can be performed, to obtain
Second bar 9, but slit 37,38 can only be defined, because it is considered that just sufficient there are two locking member 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 figure 7 as it can be seen that can one or more slits be defined as interior slit.It it should also be understood that can be selectively opposite
Knuckle joint 44a-44b and 45a-45b are moved in the substrate 41a, 42a of locking plate 41,42, as shown in fig. 6-7.Can so it be conducive to
Obtain longer locking plate 41,42,141,142, without increasing the distance between line of deflection 25a, 25b and connector 6a, 6b d.Between being somebody's turn to do
Every can be described interval smaller down to 5 millimeters or for the first bar 8.In the case of with similar line of deflection,
Corresponding distance can be identical with 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,
Start at 18 makes winner's flexible portion 28,29 according to circular shape (in the case of gripping or the drawing article drawn apart from one another)
Shape is similar shape.Because connector 6a, 6b is hard enough, and in terms of transverse plane, adjacent pivoting portions 31,32 is very short,
So there is no apparent bending 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 the angle, each locking plate 41,42 is directed away from adjacent connector 6a or 6b and against Article 2
Each contact the surface C S1, CS2 of shape object 9.Contact surface C S1 and CS2 can be respectively adjacent to one among two connectors 6a, 6b
Connector.In the case where setting slit 37 38 to define the main flexible portion 29 of the second bar 9, it should be appreciated that the contact surface
CS1 and CS2 is in opposing end portions 29a, the 29b extension of main flexible portion 29.Such as slit 37,38 high-visible in Fig. 4, selective
Being conducive to define predetermined 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,
Can any locking member that set close to pivoting portions 31,32 be kept by such contact surface C S1, 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 half just
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
It holds the top of opposite wall 4,5 and/or the drawing article 16,18 of selectivity carries out the operation, for separated anchoring element 51,52
The pressure applied manually is enough to make the fully bending of bar 8,9 (beyond angle threshold).
Angle between main flexible portion 28 and one or more pivoting portions 31,32 reaches the situation of 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 contributes to reclose in a tightening way.
Certainly, locking member that is protruding 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 C S1 or CS2.Because it is engaged by locking plate 41,42, and because of the second bar 9 and with 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) compared with the separated orientation of 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, institute interlocks for defining
The complementary anchoring element 51,52 in region 10 is still what is widened.In addition, between locking plate 41,42 and corresponding contact surface C S1, CS2
Contact can cause the equally bending of the second bar 29.For this purpose, close to the corresponding pivoting portions 31 ' of the second bar 9,
32 ' selectively set 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, in preferred option, this minimum altitude is less than 20 millimeters.
Each bar 8,9 is all fixed firmly to bag in the elongated area 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, and when pulling drawing article 16,18 to open organ type packaging bag 1, the bag material near opening 7
Expansion, and
- on the other hand, between peripheral region (including pivoting portions 31,32) of the auricle 41,42 with surrounding auricle 41,42
Relative motion,
So when opening closed system 2 every time, auricle 41,42 can pivot and easily (and repeatedly) from bag
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 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 slide fastener.
In some configurations, slidingtype slide fastener can be used, bar 8,9 is preferably made to directly constitute the part of this slide fastener.
May be employed it is many other types of re-close characteristic, 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 fixing 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 there is provided additional
Locking plate 141 and 142, as shown in Figure 5.Three knuckle joints can be set, to define line of deflection 25a, 25b.It as it can be seen that can be two
A top locking plate 41 and 42 is cut, and it is made to be oriented in opposite directions in the first flat structure.Equally, under two
Portion's locking plate 141 and 142 is cut, and it is made to be oriented in opposite directions in the first flat structure.
In the 3rd 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 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 the entrance for sealing 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 specifically shown Fig. 8 C 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, more skies are provided 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 is to be understood that preferably there is height less 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, 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 of 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 bend.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
Into the modulus of the flexible material, which is less 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
Extension, but independently pivoted compared with antetheca 4.Here, in preferred embodiment as shown in figure 15, the first bar 8 wraps
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, accurately follow the mass motion of the first bar 8；And
- each line of deflection the 25a and 25b pivots in complete open design, because the antetheca 4 of sack B is without keeping 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 beyond E4, locking plate 42 defines projection BP, and the projection is opposite
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 bar 8, in the case of 9 is curved, shoulder 39a (Figure 20), which is defined, accommodates locking plate 42
The surface (such as Figure 1A and 4) of sliding edge.Here, the projection 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 top and bottom of locking plate 42 are defined parallel to the notch 48a and 48b of the Longitudinal extending of bar 8,9.It is this to cut
Mouth 48a, 48b can be longer than the width of projection BP.As a result, line of deflection 25b with the part beyond thickness E 4 with being separated by centainly
Distance extension.This is conducive to keep flexibility along the line of deflection 25b at substrate 42a.The paper tinsel of sack B serves as a contrast 21 (as shown in figure 11)
It is contacted in the non-adhering zone of paper tinsel lining 21 with projection BP, thus it is curved in bar 8, auricle 42 is not influenced
Bending.Sack paper tinsel 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.It is convex for more commonly
The region for going out or thickening helps to increase by the tension and angle of 2 open design of closed system.Certainly, it is 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
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 of extension 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 definite height h2, and the definite height is less than associated flexural line 25a, 25b
The half of the height H8 of the bar 8,9 at place.Following relation can be met：h2/H8≤2/5.Definite height h2 can be more than or wait
In 4 or 5 millimeters.In the case where setting shoulder 39a will pass through the engagement of auricle 42, this shoulder 39a is and lower edge 8d phases
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, more than or equal to 1 millimeter.Because defining bar 8,9 using semi-rigid material, so anchoring
Element 51,52 is typically elongated and sufficiently flexible.
With reference to figure 16, it is another can be more 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.During 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 be about only 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, less than or equal to 1：5.So to locking member
Changing firmness requirements of part 41,42 and to realizing extraordinary compromise between the flexibility demand of interlock region.Anchoring element 51,52
Stem portion 53 extends in parallel, and with equal length D3, the dimension D 2 that the length can be more than first 54 is (according to stem portion
The dimension D 2 of the equidirectional measurement of Longitudinal extending).Between bar 8,9 in the region of neighbouring anchoring element 51,52

The closed system 2 of the accessory to being suitable as in packaging bag 1 illustrates now, with reference to figure 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 illustrating with lower part, closed system 2 is connected to the mode on sack B tops
It is not restricted to previous examples.
It is similar to the spoon in illustrated embodiment on 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 selection item, 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 being sold together with packaging bag 1, measuring appliance can be initially wrapped in the sack shown in Fig. 9 a, in inside
In volume V either in the separate housing defined by top 120 or in the sack being secured on sack B outer surfaces.
Enable coupling using predetermined measuring appliance 100 and 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
Should be partly the rear slit 103 of the cup-like portion 101 of measuring appliance 100 and/or ring edge 14, 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, to interact with measuring appliance 100, the bar is operated 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.Herein in fig. 11 as it can be seen that contact portion 55 can have recess or centre bore 50.Two arm portions
The base part 55a of 40a, 40b from neighbouring interlock region 10 extends downwardly into the insertion portion with linear pattern free margins 56
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, can be formed with an opposite face wherein
Some protrusions, for example, during the insertion portion 55b is inserted into guide handle 102 movement.This selective dashes forward
Go out the contact area distribution that part can be centered around between handle 102 and insertion portion 55b.
With reference to figure 9B-9C, rear slit 103 can be defined in the major part of handle 102 and at least one clamping element 106,
Between 107, clamping element Longitudinal extending 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 of the protrusion of 9 edge 8d or 9d.In sack B inner surfaces and contact portion
Gap is defined between 55, to be smoothed out using free margins 56.
On 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 slit 103 is arranged on the free end 102 or proximate to it of measuring appliance 100.Shown in Fig. 9 D
In preferred embodiment, measuring appliance 100 can have simple structure, and the structure has the slit 103 and setting towards open front
In the slotted inlets with 101 open side the same side of cup-like portion.This structure can be obtained by single longitudinal cut, generally
It is or substantially similary wide with handle 102.Due to notch, (but the notch can be substantially shorter than clip element 110, so as to the company of raising
Connect the intensity of clip element 10) and define the clip element 110 defined herein by single resilient tongue.Pass through this type
Rear slit 103, the logical of clip element 110 is defined in the case of engaged contact portions 55, it is necessary to hole 50 in rear slit 103
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, without finger is placed below contact portion 55.In fact, during storage measuring appliance 100,
User only touches free end 102a.
As shown in Figure 10, by the opening for the cup-like portion 101 that measuring appliance 100 is slided compared with linear pattern 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
The volume for dividing 101 is 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, if there is spill free margins, cannot then be smeared exactly on open side top
Flat powder, what is worse, in the case of 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 make a part of product drop, 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 compared with the material BM of sack B
At the same time radially spaced apart free margins 56 keeps base part 55a along sheet material BM.
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 substantially bend, moreover, (without crack or fracture) generally can not be folded.In the non-limiting example, because
Formed with contact portion 55 bar 8 or 9 semi-rigid material memory effect, so contact portion can parallel to by
The plane extension that interlock region 10 in 2 enclosed construction of closed system is defined, even if repeatedly smoothing out operation and repeatedly closing bag
Also it is such after pack 1.
With reference to figure 2A-2B as it can be seen that the extension L5 of prominent contact portion 55 is less than end 8a, 8b, the 9a of bar,
The height of 9b.For example, less than 20 millimeters, preferably smaller than 15 millimeters of this extension by a small margin is conducive in content 13
Floating is effectively performed in the top of 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 definite height H of internal volume V.
Make measuring appliance 100 fixed in the case of in order to be engaged in handle 102 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 on 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, clip functions are may be provided around in 102 free end 102a of handle, to keep being inserted into
Part 55b.
After amount needed for taking out, user by slit 103 engaged contact portions 55 be attached measuring appliance
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 with this virtually just
Middle face P5 intersects (Fig. 8 C and Figure 12 show this mesion P5).
In bar 8 or 9 is advantageously reduced in some options of amount of plastic, length (its larger ruler of contact portion 55
It is very little) usually strictly it is less than 1/3rd 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 by, here
In lengthwise position, and by mutually fastening bar 8,9 or closing packaging bag 1 using any appropriate closed system 2
Afterwards, make 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 measurings 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 some options, the contact portion 55 formed on the first bar 8 or 9 can form definite shape, so as to
Only as keep the holding meanss of predetermined measuring appliance 100 or can by ligule smooth out element be arranged on another
Floating element is not provided on shape object 8 or 9 or.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 or by packing in protrusion
In the case of in a similar recess defined among the bar 8,9 of bag 1, measuring appliance 100 is maintained at identical and is indulged
To storage location (general location is identical with Figure 11).
In an option, ligule contact portion 55 be arranged to can be secured under interlock region bar 8,9 it
In the individual component of one.For example, when encapsulating measuring appliance 100 for the first time, it can be this tongue bag in same sack
In.
Referring now to Figure 14 as it can be seen that prominent contact portion 55 ' can also have there are two tongue, 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 are replaced (herein by rib shape protrusion).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 local wider rear end Elastic Meshing in slit 75 are floated
It is convex.Therefore provided in this option and slip 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, contribute to main flexible portion 8 curved
It is bent.Two free margins 56a, 56b for allowing for smoothing out are shown in fig. 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 foregoing 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.So make the geometry of measuring appliance 100 there is good adaptability,
Especially, it is even more so if the measuring appliance and without well-known predetermined form.
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 attached drawing
10 form.For example, as supplementary features or instead of characteristic, at least one drawing article 16,18 can have retaining 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 the feelings in 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.It is opposite for however, it should be understood that these terms, and 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 ".
Single opening 7 is preferably wide as the bottom 3 for closing packaging bag 1, as illustrated in the depicted embodiment.But in some knots
In structure, 7 shape and size of being open can be different.For example, conical section or similar changeover portion can be arranged on sack B
In.
In addition, although two bars 8 and 9 are described as two panels semi-rigid plastics material, but it is not excluded that having
The individually option of a piece of annular semi-rigid plastics material or the semi-rigid plastics material with the interaction of at least three pieces.When
So, section or component fixed to antetheca 4 must be considered as defining the first bar 8, and section or component fixed to rear wall 5 must
It must be considered as and define the second bar 9.
Although closed system 2 is in the first structure, in the case that internal volume V is sky, sack B can advantageously make
Antetheca 4 and rear wall 5 are in flat structure, it is also possible to form another type of sack, for example, with add-in card (for example,
For defining the component of two foreboards, the function of the foreboard is similar to the antetheca 4 shown in each figure) or tool there are one or it is more
