Description

The container of variable volume
Background technology
The present invention relates to a kind of container, this container is by the variation of volume, makes that amount of air reduces to minimum in the container.
Common container all has fixing volume.As everyone knows,, so just can make food preserve the long period, therefore often need the container of many different sizes if food can reduce to minimum with contacting of air.In addition, need, produce some problems sometimes, particularly under the very valuable situation in space if container volume surpasses.
Another problem of often running into is, when depositing, and gaseous beverages meeting " deflation " or lose carbonic acid.This is to have suffered owing to gas escapes near air from beverage.
One object of the present invention is to provide the container of a variable volume to overcome above-mentioned shortcoming, perhaps provides another useful selection to the public at least.
According to an aspect of the present invention, the container that is provided comprises the scalable inner component of a basic fixed in several interlocking shells, wherein, green phase moves at least one shell for another shell, can make the container volume with scalable inner component change.
The shell of interlocking can make by mutual rotation case with being threaded togather, the volume of parts is changed.
By a ratchet, the interlocking shell is alternately moved each other.Shell can comprise the outside projecting teeth of at least two groups on one.The leader can be set, to organize the pawl of outside projecting teeth as each on lower casing.In order to reduce volume of a container, can push to shell downwards towards lower casing, and it is entered in the lower casing.In order to discharge shell, thereby increase volume of a container, can use handle or rotate mutually and go up lower casing.
By a multilayer bayonet socket attaching parts, the interlocking shell is alternately moved each other.By relative groove is set on last shell or lower casing, form multilayer bayonet socket attaching parts, each group groove comprises and the many transverse grooves of a longitudinal slot bonded assembly.Can or go up shell and extend at least two pieces of pin parts from adjacent lower casing, so that each piece pin can match with each the group groove in another shell.Shell and lower casing in the rotation make that the horizontal pin in transverse groove moves in the longitudinal slot, thereby, by pushing away/draw and rotating, change volume of a container.
Can pass through one piece of pin, scalable inner component is fixed on the base of lower casing.And scalable inner component is welded on the shell.
In addition, a lip of scalable inner component can be outstanding by an opening in the container, thereby can provide sealing between a scalable inner component and a lid.This makes scalable inner component to take away fully from shell.
Scalable inner component can be flexible shape or balloon-like.
Can be by lid with seal of vessel, lid comprises a threaded cover, and a float is installed in the cover the inside.Float has the superincumbent or integrally formed with it cover of installation, and a button part.With respect to the moving of another shell, volume of a container is reduced by a shell, and air can be by the outer ledge and the effusion of the passage between cover inner surface and threaded cover at cover.In case when liquid or other stream material arrived the float place, float began to rise, and when cover contacts with the inside face of lid, just little by little the effusion of air was stopped.
According to a further aspect in the invention, the container of the variable volume that it provides includes, and one has the shell of scalable inner bag, passes through proper device, one end scalable in-to-in volume of mobile courage makes that employed scalable inner bag volume and its content volume are basic identical.
Brief description
By below in conjunction with the description that accompanying drawing carried out, other aspects of the present invention will become apparent.
Fig. 1 illustrates the longitudinal diagram of first embodiment of the invention container;
Fig. 2 illustrates the section-drawing of half lid of first embodiment of the invention;
Fig. 3 has shown the drawing in side sectional elevation of further embodiment of this invention container;
Fig. 4 illustrates the drawing in side sectional elevation of another embodiment of the present invention container.
Describe in detail
In the being seen example of Fig. 1, container 10 comprises a scalable inner component 1.This inner component 1 has flexible shape, and is fixedly connected on the shell 14.Inner component 1 links to each other with lower casing 3 by one piece of pin 2, and it allows lower casing 3 and inner component 1 to rotate independently of each other.Lower casing 3 has identical diameter with last shell 14, and all has negative thread.The height of lower casing 3 and last shell 14 approximately is the sixth of full extension container height when opening.
Lower casing 3 and parts 4 interlockings.Parts 4 all have screw thread in its both sides, so that interlock with lower casing 3 and centre part 5.One parts 4 ' similar to parts 4 are assemblied in 14 on centre part 5 and last shell.Parts 4 and 4 ' height approximately are the sixths of container height when launching fully, the height of centre part 5, approximately be when launching fully container height 1/3rd.
Shell 3 and parts 4 negative thread 6 topmost, and the thread contour of parts 4 ' and shell 14 negative thread 6 ' bottom is littler than all the other screw threads.On the contrary, parts 4 and 5 outside thread 7 bottom, and parts 4 ' and 5 outside thread 7 topmost has bigger thread contour.Owing to is frictional fit between them, so the combination of these profiles can prevent screwed part 3,4,4 ', 5 and 14 separate.
Therefore, having the parts of screw thread and shell 3,4,4 ', 5 and 14 can be pressed downward and revolve 1/3rd of entire container height.When the parts 3,4,4 ', 5 and 14 with screw thread rotate up, can obtain the height of entire container, and screw thread 6 and 7 size can prevent that parts and shell 3,4,4 ', 5 and 14 break away from.
At the top of last shell 14, an outside thread opening 15 that cooperates with lid 9 is arranged.Lid 9 comprises a threaded cover 8, cover 13 and float 11.Threaded cover 8 connects with threaded openings 15 and cooperates.
Fig. 2 illustrates the part of lid 9.When spinning parts and shell 3,4,4 ', 5 and 14, when reducing the volume of container 10, air can be from the passage 12 effusion containers 10 of 13 on threaded cover 8 and cover.The decline of lid 9 makes that any liquid or other flowable mass in float 11 and the parts 1 contacts, and floats over above them.So just little by little promote float 11 and cover 13, finally just blocked passage 12, container 10 has been sealed.Any further interior pressure, no matter this interior pressure comes from further reduces internal volume, perhaps comes from escaping gas from liquid, all will improve the sealing effectiveness of lid 9.
Clogged cover 8 if cover 13, pinned button parts 16 with hand, but with regard to uncover, and air is overflowed.
Fig. 3 illustrates an alternative embodiment of the invention, wherein changes volume of a container by a detent mechanism.Last shell 14 has two groups of outside projecting teeths 16.Be appreciated that the tooth that can be provided with more than two groups.Pawl handle 17 is arranged on the lower casing 3.In order to reduce volume of a container, will go up shell and push lower casing downwards to.The inner of the pawl of pawl handle 17 and tooth 16 lockings are to keep the certain volume of container.Can discharge detent mechanism by moving handle 17, increase volume of a container.In addition, can rotate shell 14 and lower casing 3, discharge ratchet, thereby increased volume of a container.
Fig. 4 illustrates another embodiment of the present invention, wherein, changes volume of a container by multilayer card shape of the mouth as one speaks attaching parts.Connection among the embodiment makes lower casing 3 have two groups of groovings, and each group groove includes and the many transverse grooves 19 of a longitudinal slot 20 bonded assemblys.Last shell 14 has one piece of pin part 21 that is installed in the groove 19,20.Move (rotate and press/push away) with respect to lower casing 3 and go up shell 14, otherwise perhaps, parts 21 can move in transverse groove by longitudinal slot, thereby have changed volume of a container.
Therefore, can see, the invention provides the container that a volume can change, so that the amount of air in the container is minimum.
In aforesaid explanation, with reference to entire container with known equivalents or parts, and such equivalent here just looks like to be to illustrate separately and combined together.
Though, by explaining and describing the present invention, be appreciated that do not breaking away from spirit and scope of the invention, and can improve and revise the present invention under the situation of appending claims scope with reference to the possible embodiment of the present invention.
