Description

Packaging for foodstuff comprising inner bag

Technical field

The present invention relates to the packaging with closure lid, the closure lid, which is suitable for easily taking, to be contained in by as filling out again Fill the product in the sack of thing.More particularly it relates to suitable for more easily bellows pocket (gusset bag) is set Put the packaging for foodstuff in outer container.

Background technology

It is known that the bellows pocket with flexible sidewall for accommodating various products, the product are especially flowable Food.For example, pass through the food bag that can be refilled known to WO2014/120258.But for the content to air-sensitive and Speech, for example, milk powder or cereal preparation, it is impossible to use this sack refilled.

The bellows pocket or similar flexible pouch for being also used as sealing supply susceptibility relatively low food to secondary market.For The common bellows pocket of this purpose has two opposite gussets., can be gusset from locally unlimited structure after removing top It is deployed into completely unlimited structure.This flexible pouch (for example, as disclosed in US2011/0293208) can not be fine Ground adapts to topple over operation.

Sometimes the food content thing being initially stored in flexible pouch is accommodated with hard box.The box can fill this repeatedly The food of type.But in fact, when flowable food content thing is poured into box, often loss comes from bellows pocket or class Like the food of sack.

In addition, box is not to be particularly suitable for bellows pocket of the storage in opening-wide state because product can in flexible pouch and Flowed between box inner surface.Box is under closed state, and when whole packaging is inverted, often this thing happens.If Not over the validly blind boxes of the lid positioned at cartridge top, if alternatively, invalid by the sealing that lid carries out, produce The possible rapid deterioration of product, and may be lost there is a situation where product.

File WO2012/085117 discloses the bellows pocket being stored in box.Inner periphery is fitted possessed by cassette sidewall The annular side of guiding sack is closed, sack is in precalculated position in packaging whereby.Because being guided by cassette sidewall, Inner flexible bag can not be in container inside to movement (be adapted to box in sack).The prior art is it is known that the list for passing through inner bag This operation that a precalculated position carries out between inner bag and outer container.Bellows pocket has the bag extended to outside box top edge Lid.In order to which validly at the top of blind boxes, closed system has ring frame, the ring frame accommodates the top edge of box, pkt. flap Folding surrounds the top edge.Due to so accommodate, so the bellows pocket in precalculated position completely open wide, and sack with There is no product leakage between cassette sidewall, precondition is validly to fold and placed pkt. flap.

By this set, user is likely difficult to be accurately placed pkt. flap or ring frame.Furthermore, it is necessary to larger pkt. flap (except storing the purpose for the food being fully accommodated in box) can substantially increase before bellows pocket is integrally formed with box Volume.

File JP2012197105A, JP2012197106A, JP2012197107A, JP2012197108A, JP2012197109A and JP2012197110A also relates to the doggie bag refilled being maintained in hard box.On box top Portion, obtains the wide of sack using special insert and is open, and lid can close the top defined by insert and take opening.

The content of the invention

It is an object of the present invention to provide a kind of reclosable packaging, and whenever closure cap, the packaging can be very The content of protective packaging well, and can effectively refill.

For this purpose, the embodiment of the present invention provides a kind of packaging for foodstuff, including：

- outer container, extends lengthwise into the top surface with opening, outer container, which has, defines opening around central shaft from bottom Peripheral upper limb and define definite height internal volume side wall, side wall has two opposite inner surfaces, preferably plane,

- closed system, including frame and lid, the frame are ring-shaped and are fixed to periphery in a movable manner Upper limb, the cover hinge to frame, to enable lid to be moved between open position and closed position, in the pass During closed position, the opening of closing container with closure, frame includes the top fitting part of covering upper limb；

- bellows pocket, it is filled with food and is flexible, and the bellows pocket includes bottom, is adapted to be defined in bottom pair The upper end of the bag opening in face, the annular sidewall with least one gusset (preferably two opposite gussets), so that sack is fitted Closing from locally unlimited structure expansion becomes completely unlimited structure, shape (especially cross section possessed by outer container side wall Shape) and size matched with sack annular sidewall so that prevent sack be located at off-centerly in internal volume (sack it is predetermined Position)；

Wherein, frame further comprises：

- insertion portion, it extends in internal volume, and is radially inwardly separated with container side wall, and insertion portion is complete Annularly extend below upper limb entirely, and

- multiple axially directed extensions, it belongs to insertion portion and is configured to pass through the opening of sack and sack is nibbled Close, to keep sack to open wide, insertion portion has at two along an inner surface among described two opposite inner surfaces The recess defined between axially directed extension.

The inner surface of bottom can be completely covered in sack, and close to the side wall of outer container, so that the interior table opposite with two Face contacts, or generally coaxial with outer container side wall, and small―gap suture is left in its periphery.For more commonly, it should be appreciated that sack has Have certain size, when being in storage location in internal volume so as to the sack cannot diametrically apparent motion, in other words, It is immovable more than 5 or 6 millimeters, more preferably less than 4 millimeters.This small―gap suture usually represents less than bag width or size of equal value 9 percent or 10, and the reduced size of container is typically larger than 60 millimeters, more preferably greater than 80 millimeters.

By this set of closed system, in installation frame, due to radially extending portion, so insertion portion can have The contact of effect ground simultaneously (radially outward) promotes bag sidewalls part, due to recess, so not disturbing the expansion of sack.Because sack side The shape of wall is substantially identical with the shape of container near bottom, so without any particular/special requirement that center is placed on sack. The top of bag sidewalls does not especially extend or folds than side wall remainder, this is conducive to prevent bag material cracking.

In addition, reduce the amount of the plastic material of insertion portion to be formed, because recess usually defines two of the same side Obvious interval between axial continuation.The free margins for being spaced in axial continuation can nearby be more than 30 millimeters.

In the case where sack and container are in polygon (such as rectangle), axially directed extension can have angle respectively The free margins of degree, so as to which in each top edge of peripheral regional guidance sack, institute is defined between insertion portion and container top State outer peripheral areas.Sack is typically prefabricated bellows pocket, so the planar outer surfaces in readily available side wall, this outer surface is with holding The respective inner surfaces of device coordinate.It is to be understood that " locally unlimited structure " this statement can be corresponding with free structure, described In free structure, be open close to sack be in complete opening-wide state when size.Therefore " local to open wide " this term can be simple Ground is interpreted as " not opening wide completely " (not opening wide fully usually, to have rectangular gap between container at the top of sack).

According to a specific characteristic, among two opposite inner surfaces at least one inner surface be by with top fitting part What the panel of contact defined, and extend between two junctions, described two junctions (preferably curved) exist respectively An angle (preferably about 90 °) is defined between two adjacent panels of outer container side wall.

According to a specific characteristic, by the side that outer container is defined in its four pieces of panel that each junction is connected with each other Wall, the junction is respectively from bottom linear extension to the angle of peripheral upper limb, and the annular sidewall of sack then has four edges And there is predetermined periphery, the periphery has certain size and dimension, to be stored in by sack in internal volume And when upper limb is engaged in the groove of fitting part, each edge is separated by with one of junction is approximately less than 3 millimeters.Pass through This set, placement sack is directly perceived and simple, and the position of the top edge of sack can be as covering container side wall inner surface Liner.Because by insertion portion by sack be maintained at complete opening-wide state (make sack side wall therefore Longitudinal extending, relative to Container has identical smaller radial to interval), so avoiding the risk that sack is folded when taking out food content thing.

According to a specific characteristic, wherein a substrate from neighbouring definite hole among axially directed extension is two Extend between a recess, so the hole is not passed through by the central shaft that a part of frame defines, when lid is in enclosed construction, institute Frame is stated to be completely covered by lid.This determines that hole is typically what is defined by the fixing device of measuring appliance, and preferably justifies Shape.From in terms of the plane of central shaft, the axially directed extension in neighbouring definite hole optionally has C-shaped or L-shaped Section.

According to a specific characteristic, recess extends between two planar sections of two axial continuations, and described two A axial continuation is angled, so as to from terms of the plane of central shaft, respectively with L-shaped section.It is axially extending This partial structure is well suited for preventing near the angle of outer container surprisingly folding (sack), is in have about especially in packaging It is even more so in the case of the polygon of 90 ° of angles.

According to a specific characteristic, insertion portion includes four bridge portions, these bridge portions are tapered towards bottom respectively, There is less offset compared with central shaft, the less offset is preferably lower than or equal to 10 °, and four bridge portions include respectively：

- the recess extended between two axially directed extensions；And

- the arcuate segment extended above recess, between two axially directed extensions.

The curl of arcuate segment can define all or part of recess, and can have the curvature of more or less protrusion.

Alternatively, insertion portion has four generally planar outer surfaces, and each arcuate segment defines insertion portion The stage casing of the outer surface.

According to a specific characteristic, insertion portion meets following relation：

H-H2<5 millimeters<H1

Wherein

H1 is the maximum height of insertion portion,

H2 is the height of the flexible bellows pocket in complete open design, and

H is the definite height of internal volume.

Height H2 is the measurement from sack bottom, and the sack bottom is generally planar, and is connect with food content thing Touch.Therefore, the sack in opening-wide state is not extended to outside vessel port, difference in height (compared with the horizontal plane of vessel port) 4 or 5 millimeters can be approximately be less than, preferably about 2 or 3 millimeters.It is poor by this low height, and because insertion portion (is passed through Define) it is contained in inside pocket volume, enough height are left, so sack will not vertically break away from completely unlimited structure.More For universal, there is sack smaller radial to be conducive to fall in whole packaging to gap (being less than 2 or 3 millimeters) and relatively small axial gap Prevent bag sidewalls from substantially deforming any change of relative position (or between sack and insertion portion) in the case of putting.

Because sack top side can be usually kept not have any folding or any compression (shape of bag sidewalls and hard container Inner surface matches), so the box of partly or completely all-transparent can also be used, enable satisfactorily to show mark in bag Information on sub- wall outer surface.

In some variations, the height of sack can be relatively low so that the height of insertion portion is higher, and/or container has The similar adjusting apparatus of one or more keepers or the support sack of the certain distance to be separated by with bottom water plane.

In a preferred embodiment of the invention, at least one during further utilization is arranged below is set：

- sack and container are in polygon respectively, preferably rectangular, axially directed extension respectively have it is angled from By side, so that in each top edge of outer upper part regional guidance sack, the periphery upper area is in insertion portion and container Defined between top, when fitting part is in appropriate configuration, the periphery upper area is completely on angled free margins Side's (in general, the length of each branch of angled free margins is at least above 10 millimeters).

- insertion portion includes being fully located at four axially directed extensions inside virtual cuboid, described virtual long Cube has the rectangle first segment less than or equal to rectangle second segment, and the rectangle second segment is by sack bottom portion defining (bag The peripheral rectangular edges of sub- bottom).

- insertion portion has first recess and second recess on first recess opposite, first recess and Second recess is wider than height respectively, and sack include by first recess and second recess being unfolded respectively two are opposite Gusset.

- packaging further comprises the measuring appliance with cup and handle, is held by the fixing device in storage location Receive the measuring appliance, wherein, handle extend completely above insertion portion (be usually horizontal level by the storage location, Measuring appliance can extend above food content thing, the axially directed extension without disturbing insertion portion).

For-the first recess at least local neighborhood in the cup of storage location, fixing device is connected to the first of frame Bar side, second recess extend close to the Article 2 side of frame, and the Article 2 side is parallel with a line of frame (therefore, Cup be maintained at container central axis part separated by a distance, and the handle up for being gripped by user can be with this Central shaft intersects or is extended about in the central shaft).

The inner surface of-sack has at least one circular elastic band initially energized of two gussets of interference, its structure is just In radial and outward deformation (because its energised state and its shape memory), sack is automatically from initial locally unlimited knot Structure expansion becomes another kind structure, the close completely unlimited structure or same (by removing envelope of another kind structure Obtained this bias effect is closed after band, is usually that the initial of refill can more be held in sack of the top with confining zone Change places the structure for reaching completely unlimited).

- when being in storage location, cup is virtual relative to the container intersected with first recess and second recess Mesion deviates completely.

- frame includes the annular transitional portion between insertion portion and fitting part, and transition portion tapers downwardly simultaneously And define the concave surface that faces outwardly (curvature of annular transitional portion is adapted to radially outward promote top edge, rather than is pressed down against this Kind top edge；In addition, this transition portion is conducive to provide effective guiding function by insertion portion, it will not apply and vertically push away Action is used or unexpected tear acts on).

- annular transitional portion has radially extending portion, and the radially extending portion (is surveyed from the joint of fitting part Amount) be more than insertion portion radially extending portion maximum.

- in completely unlimited structure when, flexible pouch defines top surface, the top surface in face of the outer surface of continuous bend or Contacted with the outer surface of the continuous bend, the outer surface of the continuous bend and the annular outer surface phase defined by insertion portion It is connected with cutting, the top adjacent recess of the curved outer surface, upper limb is engaged in the groove.

- frame includes smoothing out element, and the floating element has two opposing end portions and a rigid free margins, described The rigid crosscutting central shaft of free margins extends between two opposing end portions, smoothes out element respectively in two opposed ends adjacent to phase Same axially directed extension.

- frame includes at least one elastic sealing elements, and the elastic sealing elements are more flexible than axial continuation (excellent Elect ring washer as), to define one or more radial contacts between frame in sack (locating at an upper portion thereof).

- two opposite inner surfaces are close to the interregional every smaller of container bottom, so as in internal volume lower part sack Gap between container is smaller.

Embodiment

In the various figures, identical label refers to the same or similar element.

It should be noted that described further below be directed to explaination includes box and flexible bellows pocket or not reclosable (removal top Cannot be closed after portion) it is well suited for being easily removed the food being contained in sack B similar to the packaging 1 of sack B, the packaging Product.Various products may be housed in sack B, preferably food, such as milk powder, dry beverage or solid beverage, dry powder soup, coffee, Tealeaves, whey powder or the like, buttermilk powder, condiment and other flowable solid foods.

With reference to figure 1-2 and Fig. 7, packaging 1 includes container 2 and closed system 3.Container 2 is in the side opposite with its bottom 20 Opening, and can be parallelepiped-shaped, there is the section of ellipse or any shape, bottom is wide substantially as opening, as It is understood by one of ordinary skill in the art the same.The annular sidewall 4 of container 2 extends to around vertical central shaft X and defines peripheral upper limb The top 2a of 21a.Outer lining ring 2c can be set, and top 2a can be defined as to the annular protruding portion projected upwards from top surface, The top surface is defined by lining ring 2c.It is (selective that the wide opening 21 closed by periphery 22 is defined by rigid edge 21a Lining ring 2c increases the hardness of edge 21a, with anti-deformation).

Can substantially be in the rectangle with fillet perpendicular to the cross section of 2 central shaft X of container.When stacking, it is ensured that packaging 1 Vertical intensity.The method that Fig. 7 shows stacking package 1 in more detailed manner, it is at least local using the recess in bottom 20 The roof 33 of ground packaged cap 32.The reason in order to facilitate processing, again, cross section is preferably using size as long 100 to 140 milli Rice wide 80 or 90 to 125 millimeters of rectangle are inscribed.The internal volume V of container 2, which has, determines height H, height H herein close to appearance The whole height of device 2.Bottom 20 can have bogey 20a, for example, can be relative to the downward projection of bottom of planar wall of bottom 20 Seat or annular substrates.When being configured to the additional outer layer of container 2, this bogey 20a can strengthen the intensity of bottom 20.Side The section of 4 lower part 40 of wall can be slightly narrow, as shown in Figure 1.

In the case where the side wall 4 of container 2 has rectangular cross section, two opposite inner surfaces are defined by the panel of plane The distance between F1, F2, described inner surface F1, F2 can be corresponding with the width of internal volume V.Herein out of, bottom 20 plane Surface F3 is preferably between 120 to 190 millimeters to the definite height H that top surface measures, so that box has the mark for accommodating baby milk Quasi- volume.Therefore it is relatively deep container, its opening 21 must be as wide as possible, in order to avoid take powder from close to 2 bottom 20 of container When it is difficult.In addition, this wide opening 21 makes it possible to take out powder or similar food content 5 with measuring appliance 100.

Because this substantially rectangular cross section shown in Fig. 1, the periphery 22 of the opening 21 of container 2 can be considered tool There are first long side 22a, opposite Article 2 long side 22b and first short side and Article 2 short side of the connection long side 22c, 22d.Four corners or similar junction 6 can be defined in side wall 4, to prevent forming sharpened edge.Here, the four of side wall 4 A panel has four junctions 6, and the junction is adapted to the adjacent two pieces of panels for making to be formed about 90 ° of angles to be connected with each other.

In the case where not implying that any restrictions, container 2 can be made to single hot blow modeling plastic components.For than In the case of the food content thing 5 as milk powder, the plastics are preferably multilayer materials, to form efficient oxygen barrier layer, Certainly, container 2 can also be made of other materials, be especially made of metal or couch board.

With reference to figure 4a-4b and Fig. 6, food content thing 5 is stored in sack B, and the sack has flexible sidewall 8, bottom The top that 8a and the confining zone 10 by cut away or tear define.Here, antetheca W1 and rear wall W2 and two opposite sides 9a, 9b interconnection are enclosed, is extended parallel to the longitudinal axis of flexible sidewall 8.It can set and sack B is defined at connector or sealing engagement. Confining zone 10 can be by heating seal the hermetic unit obtained.Bottom 8a can be defined by the pkt. flap in overlay structure, Wherein sealing area defines between at least two pkt. flaps.

In certain embodiments, sack B can be single web frame of film.But in a preferred embodiment, pass through assembling At least two different pieces obtain antetheca W1, rear wall W2 and bottom 8a.In this case, sack B includes multiple sealing areas, So as to each several part is sealed (for example, passing through heat sealing part).In the of the invention specific embodiments shown in Fig. 6 In, bottom 8a eliminates gusset and typically plane.Two gussets 9a, 9b have inward flange respectively, are passing through confining zone In the case of 10 or similar locking device closing sack B, the inward flange is between antetheca W1 and each inner surface of rear wall W2 Extension.

Thin-film material for forming sack B can be plastics, such as low-density, intermediate density or high density polyethylene (HDPE), Polypropylene, polyester (PET), polyamide or usually used any other material, copolymer or its mixture of packaging industry.It is thin Membrane material can be that individual layer pours or blown film, multi-layer co-extruded or laminate.Thin-film material may include one or more layers The inorganic layer and/or polymer barrier layer of paper, metal foil, vacuum deposited metal or aluminium oxide or silica, such as ethene second Enol or polyvinylidene chloride.The non-limiting example of these examples.

Important aspect is that material is pliable material, and can form gusset 9a and/or 9b.Here, two phases To gusset 9a, 9b adjacent to it is wide opening 11.Therefore sack B is bellows pocket.The upper end defined by top edge 7 is adapted to define generally It is identical with bottom 8a with opening 11 wide as the 8a of bottom, its usual shape.In addition, if film is plural layers, preferably The internal layer for being at least sack B is heat-sealable layer.

With reference to figure 6, sack B optionally has a top peripheral edge, and in order to remove this top of sack B and Before taking cutting or tear or peeling action, the content 5 of sack B can not be taken out by the single opening 11 of sack B.Antetheca Initial flat structure is generally at the top of W1 and rear wall W2, as shown in Figure 6.

In other words, until using it for the first time in the case where removing top peripheral edge (being defined herein by confining zone 10) Before, preferably content 5 (for example, milk powder or other particles or powder-product) is deposited in sack B, optionally by one Or multiple stripping tongues, tear tongue, weaker area or the like.

With reference to figure 6, the similar top of confining zone 10 or sack B preferably has a line of weakness (at dotted line), the line of weakness by Nearly top peripheral edge but extend thereunder laterally through two walls W1 and W2.For example, can be worn by laser or lancination or Scribing antetheca W1, rear wall W2 and other selective pkt. flaps form line of weakness, both can be before the wall W1 and W2 was sealed It is pierced through one by one or scribing, also it can jointly be pierced through after being sealed against together or scribing.Line of weakness One or both ends can be terminated by recess (not shown), thus make stress concentration when user opens sack B and help Torn in along line of weakness.

Here, it is enough to provide along dotted line (being linear pattern dotted line in the non-limiting examples shown in Fig. 6) simply cutting To the entrance of content 5, because the fully extension of the side wall 8 of sack B is so that each top of antetheca W1 and rear wall W2 is not at Initial flat structure.Preferably, the upper water plane of food content thing 5 and top edge 7 are separated by axial distance extension, it is described on Edge 7 extends along line of cut, and the line of cut is corresponding with dotted line (for example, upper water plane lower than the horizontal plane at edge 7 25 To 90 millimeters).

It is usually pulverulent material when sack B is in completely unlimited structure (such as shown in Fig. 4 b) inside sack B Food content thing 5 initial water plane with significantly lower than sack B predetermined altitude H2 height H3 it is corresponding.In some implementations In example, ratio H3:H2 can be between 1:2 to 4:Between 5.

Referring now to Fig. 1-2 and Fig. 4 a-4b, it is seen then that sack B once opens the internal volume V that can be stored in container 2 In.Certainly, bellows pocket B can also be stored in container 2, then opened it by cutting confining zone 10.

Although being shown as matching completely with the outer shape of container 2 in this internal volume V, however, it is understood that can root According to the concrete structure adjustment internal volume V in container 2.The height H2 of sack B, which is less than, determines height H, so that upper limb 21a is complete Extend entirely above the top edge 7 of sack B.Shape is matched with the side wall 4 of outer container 2 possessed by the annular sidewall 8 of sack B, So as to prevent sack B to be located among internal volume V off-centerly.In other words, before fixed frame 31, sack B relative to The position of container 2 is precalculated position.As high-visible especially from Fig. 1, Fig. 4 a-4b and Fig. 7, this precalculated position be because It is similar to the shape of cross section of the side wall 4 of outer container 2 for the shape of cross section of bag sidewalls 8.Bag is closely surrounded by side wall 4 During sub- side wall 8, realize that nature vertically guides the sack B for being initially at the state of filling.

Closed system 3 has annular attachment part 13 herein, and the annular attachment part includes peripheral grooves G, upper limb 21a In the groove (annular protruding portion defined by top 2a is contained in groove G at this).Herein by fitting part 13 are configured to surround the top of the ring frame 31 of opening 21.

Closed system 3 further includes the lid 32 for being hinged to frame 31, to enable lid 32 in open position with closing Moved between position.Frame 31 therefore by it is removable and closely in a manner of be affixed directly to peripheral upper limb 21a, and lid 32 and frame The then opening 21 of closed vessel 2 when the fitting part 13 of frame 31 engages.Lid 32 includes roof 33, and has and prolong from roof 33 The peripheral sidewall 34 and the interior skirt 36 evenly spaced with peripheral sidewall stretched, so as to define continuous groove CG by sidewall 34. By this set, fitting part 13 may be housed in continuous groove CG.When lid 32 is in the closed position, fitting part 13 Inner surface optionally radially contacted with interior skirt 36 (interior skirt 36 at least it is local is pressed in annular attachment part it is this in On surface), (such as powder type) food content thing 5 is gathered in the region 25 of lid and contact therewith so as to prevent.Herein As illustrated in fig. 2, this contact area 25 is arranged on the close of the angled outer surface of fitting part 13 and outer peripheral sidewall 34 Seal between surface.Therefore, can closure cap 32 repeatedly by effective sealing function.

Roof 33 is generally planar herein, to reduce the height of lid 32.Frame 31 has insertion portion 35, selectivity Ground makes frame 31 be higher than lid 32.Lid 32 and frame 31 are hinged by junction, and the junction enables lid 32 It is enough to be moved relative to frame 31 and relative to container 2 between open position shown in Fig. 1 and the closed position shown in Fig. 7, locate Opening 21 is largely close to when open position, lid 32 covers the opening 21 when in the closed position.Therefore, this It is reclosable packaging, its lid 32 uses (such as when preparing feeding bottle) to be processed each.

In this case, junction is hinge type junction 16 (being usually one or more hinges), wherein, pivot Shaft is perpendicular to central shaft X.In the shown embodiment, it is by the plastic hinge 16 of broken line formation, thus makes lid 32 and frame Frame 31 can be used as single part to produce.It is by the way that plastics (such as polypropylene) are expelled to the component obtained in mould.But It is, it is of course possible to hinge type junction 16 is obtained using two separate parts mutually assembled, and equally can be in frame 31 The junction of other forms is formed between lid 32.

With reference to figure 1, the girth that frame 31 can have can be substantially identical with lid 32, and the frame 31 is included by accessory First outside shorter side and Article 2 outside shorter side 31c, 31d that part 13 is defined, itself and first short side and Article 2 short side 22c, 22d are matched.

Although the central shaft X that shown embodiment is shown is the symmetry axis on container 2 and frame 31, naturally it is also possible to is adopted With other structures, this depends on the geometry of container side wall 4.Frame 31 is not necessarily intended to the section phase with internal volume V Same shape.In the selective embodiment with cutting element, the side wall 4 for surrounding the internal volume V for media containment bag B can It is a part of corresponding with container gusset, and including the cutting element for defining upper limb 21a.

With reference to figure 1 and Fig. 5, fitting part 13 or container 2 have the prodger that the band for locking engages edge 18.It is this to nibble Closing edge 18 can be integrally formed with the annular lining ring 2c of container 2.Packaging 1 has locking device herein, and the locking device has ear Piece T, the auricle T are downwardly projected from lid 32, are downwardly projected herein from sidewall 34.When lid 31 is in the closed position, ear Piece T occupies the position of engagement, and when in the position of engagement, lower part grip portion 19 is engaged with engaging edge 18.By using hand court Radially outward direction (being usually pulling action) is opened auricle T and is unlocked.In closed position as shown in Figure 7, adjustment is simultaneously Fixed lid 32, to realize that continuous sealing contacts between fitting part 13 and lid 32.

Referring now to Fig. 1-2, Fig. 4 a-4b and Fig. 8, pressed by the insertion portion 35 of frame 31, so as to organ Completely unlimited structure is maintained at the top of bag B, now will be described.

Open wide and be stored in sack B in internal volume V, equipped with food content thing 5 and contacted with the bottom 20 of container 2, And cannot significantly it move, because the gap between the inner surface all or in part of 2 side wall 4 of side wall 8 and container is smaller.It is actual On, shape is matched with side wall 4 herein possessed by annular sidewall 8.Therefore, sack B cannot internally placed body off-centerly In product V.In some alternatives, the lower part 40 that height H3 is preferably shorter than to height H4 configures, partly to reduce Or the small gap (size for reducing internal volume V lower parts 90) around suppression sack B.It will therefore be appreciated that container 2 is carried out Configuration, so as to define the precalculated position of the sack B with opening 11 upwardly.

It is not mounted in closed system 3 in this structure of upper limb 21a, sack B is usually not in the structure opened wide completely. Each panel of side wall 4 extends between two junctions 6, described two junctions 6 respectively with institute in embodiment as shown Angles show, preferably about 90 ° are corresponding.In the case of this angle being defined between two adjacent panels of container 2, Ying Li Solution, the corresponding corner of (being stored in internal volume V) sack B can not be substantial access to junction 6.In fact, it is usually formed bright Aobvious folding or recessed portion (usually at gusset 9a, 9b), such as shown in Fig. 1.

Herein because having gusset 9a, 9b, flexible sidewall 8 can be deployed into completely unlimited from locally unlimited structure Structure, its condition are the position of the mobile top edge 7 (under pressing effect), and hold it in away from central shaft X and along The position of the side wall 4 of container 2.For this purpose, frame 31 includes insertion portion 35, when fitting part 13 is connect by close annular When touching covering upper limb 21a, the insertion portion extends in internal volume V, and is contained in sack B (in food Above 5 horizontal plane of content).In Fig. 1, folding when being somewhat exaggerated in the structure locally opened wide, preferably to explain Edge 7 is released brokenly to separate with side wall 4.

Insertion portion 35 is radially-inwardly separated relative to 2 side wall 4 of container, obtains this because of annular transitional portion 38 herein Kind interval, the annular transitional portion 38 make insertion portion 35 (31 lower part of frame) mutual with fitting part 13 (outside frame 31) Connection.

Annular transitional portion 38 can be radially connected to fitting part 13, as shown in figure 8, in fitting part 13 and upper limb Below tight junctions between 21a.Therefore, food content thing 5 will not be escaped from container 2, because：

- the close contact at groove G；

- continuous the contact at groove CG, preferably by interior skirt 36；

If moreover, reverse package 1, food content thing 5 is inevitable to be returned to (after normal position) inside sack B, Because the position of powder or contents particles will not be moved to beyond the S38 of concave surface, this is because in sack B top peripheries part (in top edge 7, which is in extended state) is with frame 31 (in continuous transition part 38 and/or the company in insertion portion 35 Continuous annular upper end) between face contact.

In order to improve radial contact, frame 31 may include at least one elastic sealing elements (not shown), and the elasticity is close Seal element it is more flexible than axial continuation E1, E2, E3, E4, and below fitting part 13 from outer surface F5 radially outward It is prominent.Ring washer or similar annular elastic element --- be preferably provided at transition portion 38 (and usually completely recess 61, 62nd, 63,64 top) --- it is defined in one or more radial contacts between sack B and frame 31.This flexible member can be with Bending is angled, to help to be inserted into the insertion portion 35 by opening 11.

With reference to figure 2, insertion portion 35 annularly extends below upper limb 21a completely, and preferably completely can ring selection Below shape lining ring 2c.Annular transitional portion 38 substantially extends in the horizontal plane identical with lining ring 2c, and is gradually reduced downwards, boundary Fixed periphery concave surface S38 downwards.In the insertion position of insertion portion 35, transition portion 38 can abut the upper of flexible bellows pocket B Edge 7, to keep the top edge 7 to be in close to the position of 4 inner surface of side wall (including opposite surface F1 and F2).At certain In a little embodiments, top edge 7 faces this concave surface S38, without continuous or local axially contact transition portion 38.

Insertion portion 35 has multiple axially directed extension E1, E2, E3, E4, it is configured to is nibbled through opening 11 Close sack B.In the case where sack B extends in internal volume V, when closed system 3 is installed, insertion portion 35 and container Side wall 4 is sufficiently spaced from, and to make the top edge 7 of sack B surround skirt insertion portion 35 completely, leaves small gap.Guiding is prolonged Extending portion divides E1, E2, E3, E4 through opening 11 at the top of opposite inner part (angle or relative edge) place engagement sack B.Because draw Lead the pressing effect of extension E1, E2, E3, E4, when closed system 3 is in mounting structure, the Part portions of sack B first to Outer shift position, then holds it in fixed close position relative to each inner surface of container 2.

Axially directed extension E1, E2, E3, E4 are not stretched or are tightened to the side wall 8 of sack B by sack B bottoms Outside the virtual cuboid that 8a is defined.Therefore, when frame 31 is in the installment state as shown in Fig. 4 b or Fig. 7, sack B's is every A side wall 8 can be generally planar.By this structure, constant wider section of sack B is obtained, it is most suitable for utilizing measurement Utensil 100 takes out the food content thing 5 near the 8a of bottom.

Height H1 possessed by axially directed extension E1, E2, E3, E4 be more than axially directed extension E1, E2, The length for two relatively low straight edge sections that E3, E4 free end (L-shaped free margins FE) are defined.Height H1 optionally with The maximum height of insertion portion 31 is corresponding, and generally between 5 to 40 millimeters.

Preferably, the polygon with least four jiaos of the side wall 4 of sack B and side wall 8, because the interior table of container 2 Face can be generally planar, and axially directed extension E1, E2, E3, E4 can have a plane boot segment or two respectively Plane boot segment 28,29, in terms of the plane perpendicular to central shaft (X), the plane boot segment is L-shaped.Defined in sack B per side Top edge 7 be therefore maintained at the position of generally straight type, without (the imperceptible folding of user that substantially rises and falls in transverse plane It is folded).The angle of L-shaped can be not less than 90 °, this is conducive to carry according to two different directions by the same parts of insertion portion 35 For guiding function.Each axially directed extension E1, E2, E3, E4 have curved stage casing 67 (Fig. 4 a), thus define Radius of curvature is more much smaller than the radius of curvature in junction 6 or short side 31c, 31d ends.

38 buckling of transition portion, to be tangentially connected to insertion portion 35, compared with longitudinal axis X, the insertion section Divide radial deflection amplitude smaller.But this less offset is conducive to gradually increase on the transmission inner surface of container side wall 4 F1, F2 Pressure.As it can be seen that axial continuation E1, E2, E3, E4 are smaller than 38 magnitude of inclination of transition portion respectively.Transition portion 38 it is higher Deviation and the generally continuous curvature of transition portion 38 (not having horizontal plane) are conducive to prevent powder to be gathered in transition part herein Divide 38, that is, be gathered in outside sack B.

In the case where polygon is rectangular or square, the side wall 4 of container 2 is defined by four panels, four faces Plate is connected with each other in respective junction 6, the junction 6 respectively from 20 linear extension of bottom to the angle 211 of peripheral upper limb 21a, 212nd, 213,214, as shown in the non-limiting example of Fig. 1.The annular sidewall 8 of sack B has (four longitudinal directions of four edges edge 80 Edge) and predetermined periphery, the predetermined peripheral size and dimension be confirmed as --- be stored in inner bulk in sack B In product V, and in the case that upper limb 21a is engaged in the groove G of fitting part 13 --- so that each of the edges 80 and junction 6 One of distance be both less than 3 millimeters.This parallelepiped-shaped bellows pocket B structure is simple, and can be with the bag of general type Son is corresponding.

In the illustrated embodiment, insertion portion 35 may include to be connected with axially directed extension E1, E2, E3, E4 Four bridge portions 66 connect.In the case where guiding extension E1, E2, E3, E4 have L-shaped section, insertion portion 35 defines Four generally planar outer surface F5.Each bridge portion 66 (or similar recessed portion) is gradually reduced towards bottom 20, with The direction of mandrel X is compared, and has less offset.This less offset (for example, seeing Fig. 2 and Fig. 7) may be less than or equal to 10 °, preferably Less than 4 or 5 °.Because extension E1, E2, E3, E4 are more downward projection of than arch stage casing AS more, they are in free margins FE offsets are slightly more (but the usually deviation angle is identical), maximum with the interval D 2 of container 2 at the free margins.So gradually contracting Small is favourable, because in the case of being close to installation site in the position of mobility framework 31 and then being installed, gusset 9a and 9b can be moved gradually towards two opposite faces F1, F2 herein, and described two opposite face F1, F2 are preferably plane.More commonly For, it is to be ensured that there is a greater degree of progressive pressing on opposite direction (towards different side 22a, 22b, 22c, 22d of container 2) Effect.

Four bridge portions 66 include respectively herein：

- recess 61,62,63,64, it extends (for example, recessed between two axially directed extension E1, E2, E3, E4 Mouth 63 extends between two extensions E1 and E4 on the same side)；And

- arcuate segment AS, above the recess 61,62,63,64 between two axially directed extension E1, E2, E3, E4 Extension.

As it can be seen that each arcuate segment AS can define the stage casing of an outer surface in each outer surface F5 of insertion portion 35.It is logical This structure of four recesses 61,62,63,64 is crossed, only at the end of frame 31 is installed or when closing to an end, presses each top 7 stage casing of edge (here it can be seen that before pressing, at least shorter edge has V-arrangement profile), and at the end of folding, the top edge of sack B 7 can be maintained on substantially linear position along planar outer surfaces F5.

In the non-limiting examples of Fig. 1, herein along short side 22c and 22d, first recess 61 and second recess 62 Position it is relative to each other.These recesses 61,62 are preferably wider than height, and this point is also applied for prolonging along long side 22a, 22d The additional recesses 63,64 stretched.

Almost vertical structure is also advantageous by axial continuation E1, E2, E3, E4 because insertion portion 35 without prejudice to Sack uses.Protruded only for the optional fixing device 60 for accommodating measuring appliance 100 towards central shaft X, as shown in Figs. 1-5.

In some alternatives, inner periphery possessed by sack B, it, which has, contradicts and is arranged on gusset 9a, 9b The circular elastic band 65 initially energized near upper end (shown in Fig. 4 a).In the case where removing confining zone 10, this elastic webbing 65 radial and outward deformations, so sack B is another structure from initial locally unlimited structure Automatic-expanding, which approaches Complete open design or same.This alternative can be utilized to help through the 11 insertion insertion of sack B openings Part 35.

Referring now to Fig. 1-2 and Fig. 7, the cross section of axial continuation E1, E2, E3, E4 have same profile, and respectively From with L-shaped free margins FE, all free margins FE are generally in identical imaginary transverse plane (when packaging 1 is in usual position Horizontal plane) in extension.Of course, it is possible to using relatively low or comparatively high amts this angled free margins FE, this is depended on The geometry of container side wall 4.If along at least two antipodal L-extensions point or opposite of virtual diagonal L-extension point is conducive to define at least four different radially outward directions on pressing sack B inner surfaces.Cause This, the opening 11 defined by sack B top edges 7 is unfolded, and edge 7 is in the peripheral upper area around insertion portion 35 Identical axial horizontal plane is suitably positioned at, installation is in completely above angled free margins FE and in fitting part 13 During structure above recess 61,62,63,64.

Here, the smaller radial between 2 inner surface of container and sack B top halfs is substantially unchanged to gap, because top Edge 7 is without radially outwardly hyper-extended.Geometry shown in being produced on the constant surface of sack at the top of Fig. 4 a and Fig. 4 b changes Become and (because of excessive elongation bag material will not be caused to deform).

Maximum height H1 possessed by insertion portion 35 is less than the definite height H of internal volume V certainly, and usually less than 30 millimeters.In a preferred embodiment, following relation is met：

H–H2<5 millimeters<H1

It is the predetermined altitude of the flexible bellows pocket B in completely unlimited structure in this H2.It is this with reference to figure 2 and Fig. 4 b Setting ensures that top edge 7 is in the top (it is more narrower than the lower part with maximum radial distance D2) of annular space, the annular Defined between the respective inner surfaces of insertion portion 35 and container 2 (for example, surface F1 or F2) in gap.

In reverse package 1, it should be appreciated that abundance of food content 5 is gathered in by 3 boundary of closed system around insertion portion 35 In fixed volume.Here, as shown in Fig. 4 a-4b, sack B have height H2 and also in the spaced radial of every side and container 2 not More than 5 or 6 millimeters, preferably more than 2 or 3 millimeters, so there is no enough spare spaces to make it (see Fig. 7) around sack B Obvious deformation folds (even in obliquity, will not form obvious lateral protrusions).In addition, because insertion portion 35 The space of surrounding is smaller, so the insufficient pressure that (when packing inversion) food content thing 5 is applied around at edge 7 is so that sack B local deformations, therefore will not largely lose product.

Certainly, the structure of insertion portion 35 can have the recess for reducing quantity, and/or at least side of insertion portion 35 There is difference in height.For more commonly, insertion portion 35 has one or two recess 61,62, guides extension axially therein The recess is defined between two axially directed extensions in E1, E2, E3, E4, and the recess is opposite along two Inner surface F1, F2 among the extension of inner surface (herein along short side 22c, 22d of container 2).In an only recess 62 In the case of two gussets 9a, 9b, it is easier to towards not having jagged a line 31c to be slightly slanted frame 31, so this edge First gusset 9a is pushed to corresponding surface F1 or F2 by 31c.Then, than first gusset 9a is subject to second of smaller stress Gusset 9b can be unfolded by recess 62.

Recess 61,62,63,64 opens wide downwards, and is preferably not divided into several slits or thin ongitudinal recess.Molding This recess 61,62,63,64 can be obtained during frame 31 or by cutting operation.Certainly, those skilled in the art are not able to Restricted mode understands " recess " word.

Now, said with reference to figure 2-3, Fig. 5 to Fig. 7-8, the setting of pair device to interact with measuring appliance 100 It is bright.

The measuring appliance 100 explained on Fig. 3 and Fig. 5, it is similar to the spoon in illustrated embodiment, in other words, tool There is cup 101, the cup defines measurement volume, and in this alternative, substantially in cylinder, until the cup The open side of shape thing 101.Handle 102 extends to free end from cup 101.Measuring appliance 100 therefore in elongation in the form of, and And it is made of plastic material or equivalent material.On bulge 2, the length of measuring appliance 100 is necessarily less than frame 31 certainly Internal diameter.On rectangular vessel 2, which is necessarily less than the inner opposite angle line of frame 31.Measuring appliance 100 is the survey of predetermined form Device is measured, it is preferably designed to together sell with entirely packaging 1, may not have bellows pocket B in some alternatives.But It is to be understood that the fixation measuring volume of this measuring appliance 100 is to be directed to discussed content 5, said content is Such as food as milk powder.

In the case where together being sold with packaging 1, measuring appliance 100 can be initially wrapped in sack, in internal volume V, And/or below 32 roof 33 of lid, or in the independent sack for being fixed to 2 outer surface of container.At least it is being initially opened After closed system 3, measuring appliance 100 can be accommodated by the hole 60a in fixing device 60, the fixing device 60 is in frame Formed on 31, and be preferably integrally formed with frame 31.Hole 60a's is sized to holding cup 101.Gu Determine device 60 to be integrally formed with closed system 3 herein, and between at least one base part and at least one free margins 72 Extension, the base part is connected to short side 31c, and the free margins 72 is selectively configured to smooth out the one of element 70 Part.Fixing device 60 is essentially perpendicular to central shaft X extensions herein.With reference to figure 2, size is more than 101 open side of cup Free margins 72 can be curved or linear.Rigid free margins 72 can be connected to 31 inner annular surface of frame Floating element 70 two opposing end portions 73,74 between extend.It (is herein square to smooth out element 70 and may be connected to polygonal frame Shape frame 31) two adjacent sides.Therefore end 73,74 can be respectively adjacent to the same axial extension E4 of insertion portion 35.

It is relatively fixed device with free margins 72 as shown in figure 8, can be defined in joint by annular transitional portion 38 60 base part BP, the annular transitional portion 38 Longitudinal extending between fitting part 13 and insertion portion 35.Free margins 72 can have relatively low protrusion, so as in the case of without inclination measurement utensil or the position by being slightly slanted carry out Smooth out.Therefore user without nearly vertically inclination measurement utensil 100, can so cause some food content things 5 to drop simultaneously Therefore cause measurement inaccurate.

In one embodiment shown in Fig. 1-4B and Fig. 8, can neighbouring free margins 72 set stabilize relief 60b or At least one similar protrusion projected upwards, and it is set to around opening 60 26 extension.Fixing device 60 With hole 60a, for example, round hole, so as to which measuring appliance 100 is stored in storage location, in the storage location, handle 102 Extend completely above insertion portion 35, be substantially parallel to the roof 33 of lid 32.Minimum altitude possessed by cup 101 More than the space between 32 roof 33 of hole 60a and lid, so when closed system 3 is maintained in its closed position, measuring appliance 100 It will not escape.

Here, first recess 61 at least local neighborhood is in the cup 101 of storage location.Cup 101 can be along Axially directed extension E4 extensions, the joint close between short side 22c and long side 22b.Fixing device 60 may be connected to frame The a line 31c of frame 31 and the another a line for being used to selectively connect to neighbouring a line 31c.Have in insertion portion 35 In the case of two opposite recesses 61,62, second recess 62 extensible Article 2 side 31d close to frame 31, described the Two articles side is parallel with a line 31c.Handle 102 extends from cup 101 towards Article 2 side 31d.

In order to make 32 top surface of lid, close to the plane of the opening defined by upper limb, lid 32 is in substantially flat structure, and have Bounded determines the roof 33 of planar top surface, and measuring appliance 100 extends along the planar top surface when in storage location.Here, It is curved to smooth out edge 72.

As it can be seen that the distance between hole 60a and upper limb 21a D4 are typically smaller than each axial continuation E1, E2, E3, E4 Maximum height H1 and the characteristic size D3 (for example, internal diameter) less than hole 60a.Distance D4 can be set smaller than 10 millimeters, it is excellent Choosing is less than 5 or 6 millimeters, it means that the interval D 2 between free margins FE and outer container 2 may be typically smaller than 3 or 4 millimeters.Hole Therefore the distance between 60a and central shaft X D5 can be at least 20 or 30 millimeters, this be conducive to smooth out operation (within easy reach, and Measuring appliance 100 need not be tilted to more than 45 °, even if length possessed by this utensil with along container 2 short side 22c, The opening size of 22d it is similar or more than the opening size in the case of, be also such --- for example, seeing Fig. 5).

Although Fig. 1-4B show fixing device 60 and/or smooth out the free margins 72 of element 70 in the angular region of rectangular frame 31 Domain, it should be appreciated that, the setting of the such device to interact with measuring appliance 100 can be different.For example, figure 7 show retaining element 60, by free linear edge 72 possessed by the retaining element be arranged to it is two opposite short Side is vertical, separated by a distance with angle.

In the variation shown in Fig. 5, it is seen then that and the fixing device 60 formed on frame 31 is connected solely to a line 31c and the bent portion away from frame 31.In storage location, neighbouring cup 101 sets clip 69, will pass through and one Departure handle 102 engages and locks the position.Certainly, fixing device 60 can also form linear pattern free margins 72.

In the variation explained in figures 9-10, pass through the exterior recess below outer lining ring 2c and/or in the outer lining ring 2c The inside relief 39 of middle engagement frame 31, and frame 31 is attached to container 2.Internal relief 39 is defined in groove G, and from The annular outer wall of frame 31 radially-inwardly protrudes.With reference to figure 10, corner CP possessed by outer lining ring 2c can have recess 82 respectively, The recess is obtained by the local height that reduces.At the angle of frame 31, internal relief 39 can be defined below each window 37.This Sample adds the local pliability of frame corners, and therefore contributes in groove G the outer lining of the inside relief 39 and container 2 defined Cooperation is slipped between circle 2c.It is to be understood that such frame 31 is attached any one being applicable in the embodiment And any other variation.Surface possessed by peripheral upper limb 21a can rounded cross section, this is conducive to (by gradually increasing Contact force) groove G interior of the insertion with internal relief.Pass through this set, the frame 31 of closed system 3：

- on the one hand, it is (and not special for a part for lid 32 is attached to container 2 to be fixed firmly to container 2 It is required that)；

- pass through specific impetus (this promotion under two corners defined by frame 31 in the same side at the same time The corresponding internal relief 39 of the same side release is acted on, to obtain disengaging configuration) it is easy to the frame 31 of the closed system 3 Removed from container, then by the outer lining ring 2c relative to container 2, simply pivot frame 31 (passes through to remove closed system 3 Other internal reliefs 39 of turning effort release opposite side (being usually hinge side)).

As in previous embodiment, there is provided engagement edge 18 ', will pass through the closing knot of fixed ear piece T interlocks lids 32 Structure (for the sake of clear, do not show lid, this lid has been described in Fig. 1 and Fig. 5) in fig.9.It is but here, this Engaging edge 18 ' is formed on the frame 31 shown in Fig. 9.Certainly, this option is applicable to previous embodiment.Preferably this Kind is set, to simplify container 2.

Frame 31 shown in Fig. 9 is similar to the frame shown in Fig. 1 and Fig. 5, does not show the hinge connection with lid 32.Though The position of the hole 60a so defined by fixing device 60 is identical with the position shown in the embodiment of Fig. 1-2 and Fig. 4 a-4b, still Insertion portion 35 is slightly different herein.In fig.9 as it can be seen that axially directed extension E4 ' from the substrate 43 of adjacent bores 60a two Extend between a recess 61,63.When closed system 3 is in mounting structure, in terms of the plane perpendicular to central shaft X, adjacent bores The axially directed extension E4 ' of 60a optionally has C-shaped or L-shaped section.Substrate 43 can be tied with base part BP phases Close (Fig. 8).

Here, recess 62 and 64 is more less than the respective notches protrusion in other embodiments.In addition or as selection, axis It is more slightly larger than the example magnitude of inclination of Fig. 1-2 and Fig. 7 to extension E1, E2, E3, unlike, axial continuation E4 ' is thin Long, and it is narrower than remaining axially directed extension E1, E2, E3.Make some axially directed extensions it is more inclined this Kind is provided with beneficial to making sack B easily engage, and it is properly positioned at the top corner of sack B especially by user.

Figure 10 illustrates the fact that shape of container side wall 4 is matched with the annular sidewall 8 of sack B.Make container 2 herein Length L1 is significantly greater than width L2, it is impossible to which unlimited sack B is contained in the precalculated position in 2 internal volume V of container not Same other vertical positions.Here, " matching " word is meant that shape (form) is identical or fully similar, put not to prevent stop bit When in the improper position, sack B side walls 8 do not extend along the side wall 4 of container 2.It is well known in the art that this form fit (for example, refering to bag in box system and similar refill system) is and this area in order to which inner bag B is contained in outer container 2 This point is well understood in technical staff.Although it have been described that the height H2 for opening wide sack B is sufficient for relation H-H2≤5 in the least Rice, however, it is understood that sack B not necessarily has constant height H2 because there is provided recess or it is non-protruding it is irregular in place of, It is preferred that, correct guiding function without weaken insertion portion 35 separated by a distance with angle.For example, can be only in unlimited sack This relation is verified at the top corner of B.

As it can be seen that central shaft does not pass through hole 60a in Fig. 1 and Fig. 5.This point be also applied for shown in Fig. 9 in frame 31 The hole 60a defined by fixing device 60.Due to the horizontal storage position of measuring appliance 100, it is possible to obtain the phase of lid 32 To flat structure, this utensil can be at least partially inserted into the internal volume V of container 2.

In these different embodiments, handle 102 is easy to grip, and without contact at cup 101 or at it Neighbouring measuring appliance 100.The handle 102 of measuring appliance 100 extends in the plane of opening 21 or above upper limb 21a, this Mean that the finger of the user when gripping measuring appliance 100 does not contact the inner surface of sack B.Handle 100 is outside sack B Middle position is conducive to avoid the contact that may easily make food content thing 5 degenerate.

Therefore, multiple features can be combined by packaging 1, and not weaken the effect of closing, and remove empty bag Afterwards, the new sack B equipped with content 5 can be reused.The processing of the frame 31 of closed system 3 does not bother, Er Qiewu It need to place a finger in new sack.

It is obvious that the not in any limiting sense embodiment of embodiment described above, is not departing from required the scope of the present invention In the case of, there may be many variations, form the geometry of the part of container 2 and closed system 3.

For example, although closed system described herein 3 is made of one-piece molded plastic, however, it is understood that can profit Closed system is defined with the combination of two or more elements.For more commonly, it is evident that use verb " comprising " and its morphology Change is not precluded from addition to element defined in claim that also there are other elements.

Wording as "a" or "an" before the element is not precluded from that there are multiple this elements.Following right will All labels in asking must not all be interpreted as limitation claim.

Certainly, the size of the inner periphery of container 2 is not necessarily as the annular sidewall 8 of sack B, so that sack B is outside It is fitted close in container.Overall fitting is enough, and more commonly for, the inner periphery of container 2 is adapted to the ring for guiding sack B Shape side wall 8, so that the precalculated position in the internally positioned volume V of sack B.
