The specific embodiment
The operation of a kind of flexible membrane container and this container of manufacture is provided.Those defects that this container has the self-supporting ability and do not exist existing package design usually to exist.
Fig. 1 is the transparent view according to the flexible membrane container 100 of an exemplary embodiment.As the decomposition view of the schematic cross section of Fig. 2 a and Fig. 2 b was clear that, flexible membrane container 100 comprised top 110, base portion 130 and mediates top 110 to be connected to the body 120 of base portion 130.In this embodiment, the part that top 110 and base portion 130 form separately, separate, they are linked to body 120 to form container 100 subsequently.
Still referring to Fig. 1,2a and 2b, the body 120 of container 100 is multi-sided, so container 100 has the sidewall 121 of at least three separation.In typical embodiment, body 120 has the sidewall 121 of four separation, thereby container 100 is cuboids.The continuous netware structure of body 120 use membrane materials, its opposed end for example connects with heat seal or welded lap.
Flexible membrane for vessel 120 is any suitable film that uses at package.According to some exemplary embodiments, very thin film can be used to form other parts of vessel 120 and/or container 100, and the container of semi-rigid and self-supporting still is provided.Film can have approximately 25 microns to the about thickness of 250 micrometer ranges, is generally approximately 75 microns to approximately 150 microns.
Film can be the monofilm material.In certain embodiments, film can be instead MULTILAYER COMPOSITE or laminated film.Can be set to barrier layer by one or more such layers, to keep the fresh of container contained object.The suitable material that uses in film (or as individual layer or as the membrane element of multilayer) for example comprise ethylene-vinyl alcohol copolymer, polyamide, polyacrylinitrile, polyethylene terephthalate, polyalkane (polyalkene) (polyolefin), poly(lactic acid) (polylactic acid) (PLA), cellophane and take the film of biological plastics (bioplastic-based) as base.Should be understood that in some cases, the selection of concrete membrane material and/or these materials order of placement in laminated film can be depended in container 100 the concrete contained object of depositing.For example, for depositing chocolate container, expectation can obtain penetrablility, and this container and contained object are that the situation of nut or dry fruit is different.
Base portion 130 is provided to the bottom (for example seeing Fig. 2 b) of container 100.Base portion 130 forms the part that separates with vessel 120, usually but not necessarily also by flexible membrane, formed.Should understand, although base portion 130 can use the material structure different from flexible membrane (to comprise rigid material, the thermoplastic material of cardboard or injection-molded for example), the characteristics that can be used to form the flexible membrane type of base portion 130 be as above, for those materials of vessel 120.
Base portion 130 can comprise knuckle 132, and knuckle extends and the surface that identical border is arranged with body 120 lower edges is provided around the periphery of base portion 130.Base portion knuckle 132 can help the manufacture of container 100 thus by overlapped surfaces is provided, by overlapped surfaces, base portion 130 can be attached to body 120 to form seam.The increase thickness of the seam that in succession forms (at these place's base portion knuckle 132 contact bodies 120) helps to make container 100 self-supportings.
Base portion 130 can be attached to body 120 by heat seal, welded lap or by some additive methods that base portion knuckle 132 is heat sealed to body 120.As Fig. 2 a, know finding, base portion is sized on the inside face that makes base portion knuckle 132 be positioned at body 120.Yet, can be sized to base portion 130 to make the outside of base portion knuckle 132 at body 120.
As shown in Figure 2 a, base portion knuckle 132 is shown as towards the space that is limited by container 100 and extends.This provides flat bottom for container 100, causes stacking better and increasing head room.Perhaps, base portion 130 can be constructed to base portion knuckle 132 extends and leaves from container 100, namely opposite with the structure of (with shown in Fig. 2 a-1) shown in Fig. 2 a.This replacing structure has reduced the space in container 100 by the height of base portion knuckle 132, because the first type surface of base portion 130 replaces base portion knuckle 132 to put in container 100.
Container 100 also comprises top 110.Similar base portion 130, top form the part that separates with vessel 120 and usually also with flexible membrane, form.Also be similar to base portion 130, in certain embodiments, replace flexible membrane, rigid material (for example cardboard or injection molded) structure can be partly used at top 110.
Top 110 comprises the hole near the contained object of container 100 for the customer.Hole can be formed in top 110 during manufacture.Alternatively, by by the customer, removing the perforated portion 112 that is formed in top 110, can complete the hole near the container contained object.The use of perforated portion 112 can be used for being provided at the customer and buys the sign (evidence) that whether the container contained object changes or approached in addition before goods.
In certain embodiments, top 110 can comprise covers 115, usually also with flexible membrane, forms.Lid 115 can comprise salient 117 and can be attached to top 110 by lining cement, cause lid can be from top 110 separate or otherwise remove, (or removed perforated portion 112 is wanted in exposure to expose the 110Zhong De hole, top that is formed on container 100, to form hole) so that near the contained object of container.Lid 115 can attachedly for good and all be removed from container 100 with being configured to.Alternatively, lid 115 can seal repeatedly.The use of the lid of sealable can be remained the fresh of container contained object and prevent from spilling.In the embodiment of the lid 115 that uses sealable, lid 115 one or more edges or bight for good and all are attached to top 110, simultaneously by lining cement or allow cover 115 and repeatedly open and with other parts that are sealed to again top 110, will cover 115 one or more other edges or bight and removably be attached to top 110.Further should be understood that in certain embodiments, lid 115 can form with top 110 and is integral, and to realize covering 115, forever is attached to top 110(and sees Fig. 4).
In addition, as shown in Figure 2 b, top 110 can comprise top knuckle 114, so that the surface that identical border is arranged with the upper limb of vessel 120 to be provided, so that by heat seal or form welded lap or other appropriate method of two parts 110,120 of connecting container 100 are attached to vessel 120 by top 110.As shown in Figure 2 a, top knuckle 114 is vertically located and is extended and leave from container 100, the upper limb 124 of vessel 120 folds into top knuckle 114 tops, makes the thickness of seam equal thickness for the film at top 110 and adds the twice for the thickness of the film of body 120.Can be by extra introducing top, folding part knuckle 114, base portion knuckle 132 or vessel 120, to increase the thickness of seam.As shown in replacing structure shown in Fig. 2 a-2 and 2a-3, the upper limb 124 of vessel 120 is attached to top knuckle 114 by the seam that does not double on the upper limb 124 of body 120.
The signal of Fig. 2 a-2 and 2a-3 there is shown the adjacently situated surfaces of the container features 110,120,130 that forms upper and lower container seam 117,137, between surface, has the interval for the separation characteristic of showing large described part.However, it should be understood that these neighbouring surfaces of sealing cause close contact and the integration at seal point place part, to form seam.The whole periphery of the common wrapped piece installing of this seam extends and seals fully guaranteeing.Described seam is provided to container 100 by extra structure, makes container top 110 work when being attached to vessel 120 with bottom 130, to realize the self-supporting of container, and irrelevant with the structure of flexible membrane.
Forward Fig. 4,5a and 5b to, the flexible membrane container 100 shown in figure is for comprising pleated portions 125, and this pleated portions is the overlapping folding part that is formed in vessel 120.Pleated portions 125 is configured to pillar, in substantially vertical mode, locates and increased the intensity of container 100.Pleated portions 125 helps to make container 100 to realize self-supporting thus, especially in the height of container 100 approaches or surpasses the embodiment of container 100 length or width dimensions.As shown in the figure, pleated portions 125 is formed in the sidewall 121 of body 120, is positioned on each side in bight 126 of adjacent body 120.Yet pleated portions 125 can be formed directly in bight 126, or, at the near middle of sidewall 121, leaves bight 126.In some cases, be desirably in some combination of the different parts introducing pleated portions 125 of body 120.
Embodiment shown in Fig. 4,5a and 5b is also cuboid, is cube substantially in this embodiment, have the taper that slightly reduces from the top to the bottom, so the area of base portion 130 is less than the area at top 110.Yet container can be also the taper that slightly reduces from bottom to top.The use of taper can further improve self-supporting characteristics and its stacking property of container.According to the angle of taper, can be used to form by cutting, folding or other operation adjustments the flexible membrane of vessel 120, to consider needing material still less having than the container end portion place of small size.
Alternatively, in certain embodiments, container is not taper along either direction, has all vertical orientated sidewalls 121, so body 120 is perpendicular to each of top 110 and base portion 130.Although the embodiment shown in Fig. 4-5b shows pleated portions and conical body, it should be understood that, needn't use these features in the mode of combination.
Except the geometric configuration that shows cuboid, container 100 can have any multi-sided geometric configuration and be prism in one embodiment.That is, top 110 and base portion 130 can be polygons, and it forms two consistent, parallel or substantially parallel base portions, and it links by vessel 120.A plurality of sides of body 120 for example can be by manufacturing vessel 120 and/or forming when body 120 is attached to the seam of top 110 and base portion 130 by film fold is formed, and this is further used for body 120 is remained on the specific geometric configuration of expectation.
So some exemplary embodiments form flexible membrane container 100, although form container 100 with flexible membrane, by being connected to each other of top and bottom member 110,130 and body 120, keep orientation, this makes it have semi-rigid and self-supporting characteristics.Even so the container 100 of structure also can stack and keep its shape in sky.Therefore, according to the container 100 of some exemplary embodiments, do not require in container or vessel 120 forming processes in use carriage, cardboard or other rigid strutting pieces.This container 100 can stack and provide better shelf to show, comprises the greater room for drawing and other brand key elements.The shape of container 100 and structure also allow its interim plate as can directly consuming contained object easily.
