The description of embodiment

Referring to Fig. 1 a and 1b, Fig. 1 a and 1b represent the preferred embodiment of container of the present invention, and it is in a kind of by the state that is filled with liquid contents and does not break a seal.Container 1 is particularly suitable for the liquid food product, for example milk, fruit syrup, water or wine.

Container 1 can flatten form, and is promptly compressible or collapsible, and comprises three walls, i.e. two relative sidewalls 2 and a diapire 3.

These

walls

2,3 can be by the plastics manufacturing, perhaps preferably by the material manufacture of the adhesives of a kind of additive that comprises mineral material and a kind of polyolefine material.Additive is chalk advantageously.

Wall

2,3 further is connected to form a chamber 4, and its volume depends on the relevant position of

wall

2,3, as shown in Figure 2.Two sidewalls 2 pass through solder bond along a connecting bridge 5.

Flexible wall

2,3 forms like this, and has such rigidity, promptly described sidewall 2 in actuating state not promptly corresponding to the state of the sky of container 1, mutually against fitting into a plane.If wall comprises the additive of a mineral base, chalk for example, described rigidity is mainly obtained by additive.When container 1 of the present invention is filled with liquid contents, content will make

wall

2,3 be actuated into such degree, and promptly they present a relative position, and its lumen 4 limits one and holds the required volume of content.

Container 1 is crushable as mentioned above, this means that it is reduced by the volume that chamber 4 limits when wherein content of container 1 emptying.

A bogey 6 is arranged on connecting portion 5, in first side of container 1, and comprises an open area 8 in described embodiment, has one first circular basically opening 9 and one second elongated basically opening 10.As a result, bogey 6 forms a handle 11, and it makes the user to mention container 1 by enough four fingers, and a load absorption portion 12 forms between opening 9,10 simultaneously, prevents the otherwise folding or distortion of handle 11 of container 1.Two openings 9,10 of handle 11 extend into about ground, 25 ° of angles with the perpendicular line of container 1.Test verifiedly, the result of use of the handle of the container 1 that one 20-30 ° angular range produces is good.

Referring now to Fig. 2,, it is the top plan view of Fig. 1 a and 1b, and immediate sidewall 2 is removed.Can see the inboard of rear wall 2 now,

diapire

3 and 5, two sidewalls 2 of connecting bridge interconnect.At the bottom section 13 of container 1, sidewall 2 is connected with diapire 3, on the one hand, makes each sidewall 2 be connected with diapire 3 through a following connecting portion 14, makes three all

walls

2,3 interconnect at public weld nugget through two side connecting portions 5 on the other hand.Therefore the chamber 4 of container 1 is limited by sidewall 2 and diapire 3.The boundary line 16 that connecting portion 5 forms in the face of chamber 4.

Chamber 4 comprises a bottom section 13, as mentioned above, a central area 17, its boundary line 16 in the face of the connecting bridge 5 in chamber 4 is parallel, with a last arch area 18, extend in the face of arc ground, ground mutually its boundary line 16, but not in the exit region 19 places extension of second side 20 of container 1, detailed hereafter exit region 19.This design makes container 1 stably to stand, and does not rely on filling operation.

When container 1 stands up during the position shown in Figure 1, the principal part of liquid contents is collected in the bottom section 21 of container 1, and described bottom section 21 is formed by bottom section 13 and central area 17.

Container 1 of the present invention also has a pipe installation 22, and it is arranged on the described exit region 19 apart from bottom section 21 certain distances.Therefore pipe installation 22 is set at second side 20 of container 1, and relative with described first side 7, bogey 6 is arranged on first side.

Pipe installation 22 is integrally formed with sidewall 2.Particularly, pipe installation 22 is formed by a wall portion 23 of each sidewall 2.The longitudinal axis of each wall portion 23 and container extends at angle, and therefore forms the projection that extends laterally on each sidewall 2, and wall portion 23 interconnects along its side, and therefore it be included in the described connecting portion 5.Therefore interconnective wall portion 23 forms described pipe installation 22, is communicated with the chamber 4 of container 1 at first end 24, is sealed by described connecting portion 5 at second end 25.Because described wall portion and pipe installation 4 extend with the longitudinal axis of container 1 at angle from the chamber, this pressure that acts on the wall of container of guaranteeing the liquid content deposits yields does not diffuse into pipe installation.In the embodiment shown in Figure 2, pipe installation has an extension that is substantially perpendicular to described longitudinal axis.It should be noted that pipe installation 22 comprises two wall portions 23, it is flexible, and respectively has an inside face 26 that along its limit portion sealing the state of its inside face is the actuating that is not subjected to described content, reclines mutually.

In order to open container 1 of the present invention, second end 25 of pipe installation 22 is by cutting off or the similar operation removal.Certainly, but this cut-out can form an opening that has selected angle.A container of opening like this 1 is shown in Fig. 3 a and 3b.

When container 1 of the present invention presented described stand up position, liquid contents was collected in the bottom section basically 21 in chamber 4, and as shown in Figure 4, Fig. 4 is the cross-sectional figure of container 1 shown in Fig. 3 a.Should be understood that when the content in the container also is not drained some contents may remain on the arch area 18 of container 1.Content will act on the bottom section 21 of sidewall 2, make sidewall mutually away from, present a relative position then, to increase the volume in chamber.But the arch area 18 in chamber 4 does not keep any content, perhaps as mentioned above, has only the sub-fraction content, thereby the sidewall 2 in this zone reclines mutually, causes the volume in chamber 4 to increase then.But the increase of volume reduces greater than volume, and this causes forming negative pressure in the chamber 4, and it hinders the increase of volume.

Fig. 5 represents the action of toppling over of container 1 of the present invention, and Fig. 6 is the cross-sectional figure of container 1 shown in Figure 5.Container 1 is moved, and from stand up position to a position that turns forward, Fig. 6 represents how some contents enter the arch area 18 in chamber 4, thereby causes the volume in this zone 18 to be increased to a certain degree, the reducing of volume of compensation bottom section 21.The relevant variation of volume is adjusted by this way, and promptly the significant negative pressure in the chamber 4 stops.

Fig. 7 a-7c represents how above-mentioned container of the present invention 1 is grasped and topples over the liquid contents that remains in the container 1, for example milk.

Fig. 7 a represents that the container of opening 1 is in stand up position, on a base portion.Liquid contents is collected in described bottom section 21.

Fig. 7 b represents container 1 at the state that is raised, and the action of toppling over makes some contents that remain in the container 1 enter the arch area 18 in chamber 4 and relevant exit region 19 from bottom section 21.Liquid contents will forward pipe installation 22 to, thereby apply a pressure, and the wall portion 23 of pipe installation 22 and inside face 26 thereof are separated, and pour out in some contents to one cup 27 allowing.Because some contents enter the arch area 18 and the exit region 19 in chamber 4 from bottom section 21, the pressure that is applied to by described content on the sidewall 2 of bottom section 21 reduces, and sidewall is moved mutually in opposite directions, causes the volume in chamber 4 to reduce.This volume reduces relatively to increase greater than the volume at described arch area 18 places, causes the significant negative pressure in the chamber to stop.

Finish and topple over action, content no longer applies any pressure in the wall portion of pipe installation certainly, and therefore the inside face 26 of wall portion presents the state that reclines mutually again.

In Fig. 7 c, container 1 has entered stand up position again.Content is collected in described bottom section 21 again, this means that content exerts pressure on described sidewall 2 again, therefore causes the volume in chamber 4 to increase.

The increase of this volume means, produces a negative pressure that hinders the increase of this volume in chamber 4 again.This negative pressure makes the partial sidewall that does not comprise liquid contents 2 in the chamber 4 shrink, therefore this part forms the arch area 18 of container, and may comprise the bigger or less part of bottom section, therefore depend on the packing density of container, and guarantee that described sidewall 2 in the described part in chamber 4 keeps the state that reclines mutually.

Pipe installation 22 is suitable for responding the negative pressure that produces in the chamber 4 and cuts out.In an illustrated embodiment, this means that the inside face that reclines mutually 26 of the wall portion 23 of pipe installation 22 presses mutually, and therefore form a gas tight seal.The longitudinal axis of pipe installation and container extends at an angle, guarantee can not involve pipe installation by the pressure that liquid contents is applied on the wall of container, so pipe installation can not be under pressure the effect and be opened.The result is, obtained the prolonged sealing of container 1, prevents that atmospheric air from entering into the chamber 4 of container, is affected content.

Container 1 therefore self sealss durably of the present invention this means, do not need the durable sealing device of machinery, for example lid or clip.

In order repeatedly to pour out content, only need mention container 1, carry out the action of toppling over of a repetition, thereby negative pressure stops.When action was toppled in one of execution, content was exerted pressure, and as mentioned above, made the wall portion 23 of pipe installation 22 separate, thereby allowed content to pour out once more.

Experiment confirm, the prolonged self sealss ability of container 1 does not rely on the packing density of container basically.

Therefore the present invention relates to a kind of prolonged self sealss of container 1.Particularly, container 1 comprises a pipe installation 22, and it can be opened by cut-out.And container 1 has

flexible wall

2,3, during controlling container 1, this flexible wall is activated by the liquid contents that remains in the container 1, by this way, and when action is toppled in execution, by wall 2, the volume in 3 chambeies 4 that limit reduces, and when container 1 was turned back to stand up position, this volume increased.Described volume increase causes producing negative pressure in chamber 4, and this negative pressure hinders the increase of volume, and guarantees that the pipe installation of opening 22 is sealed.Extending laterally of pipe installation 22 promptly guaranteed not diffuse into pipe installation by the pressure that acts on the wall of container that content produces with the fact that the longitudinal axis of container extends at angle.The result is, a durable sealing is guaranteed, prevented that air from entering and its influence to content from the chamber 4 of container 1.

In order to ensure the gas tight seal of the pipe installation 22 that responds the negative pressure that produces in the chamber, the inside face 26 of pipe installation 22 has very high Pingdu.

Fig. 8 represents according to another embodiment of the present invention, and it has one and 4 becomes a pipe installation 22 that extends less than 90 ° of angles with the longitudinal axis of container 1 from the chamber.

The embodiment of the container 1 shown in the present invention obviously is not limited to; For example, pipe installation can with container 1 one, promptly it is outstanding from container 1, and is only 4 outstanding from the chamber.Therefore several improvement and variation are feasible, and the present invention is limited exclusively by the claim of enclosing.
