Description

Collapsible container

Technical field

The present invention relates generally to the molded plastic container of the type of the various uses that is usually used in comprising storage food or non-edible article, and such container preferably is suitable for admitting suitable sealing member or lid.More particularly, the invention relates to such one type container, this container is not to be rigidity as traditional bowl tool, but in sky the collapsible state that can be folded into a compactness in other words so that store.

Background technology

The container of general in the prior art known such, cup, bowl and similar type, and these containers have various forms.These containers comprise contractile cup or glasswork, and wherein glass is formed by the stacked annular wall part of telescopically, and these annular wall parts can slide between the state of the state of full extension and contraction relative to each other.When wall spare is not whole when forming and being free to slide relative to each other, seepage just takes place possibly, and except as the practical use that does not have other the temporary transient drinking container.Authorize the collapsible container that another form more relevant with the present invention has been described in No. the 5th, 439,128, the patent of Fishman in August 8 nineteen ninety-five.In the container of Fishman, wall spare is Unitarily molded, comprise replace stacked to form the member of the vertical and bevel of a group of wall of container.All members corner connection portion betwixt links into an integrated entity by film hinge, and all wall spares are folding around these film hinges.The actual folding downwards and contraction of Fishman member requires the member bending to adapt to jackknife action.This is fairly obvious except also need the situation of the actual flexion of all members film hinge place folding, so that at least in some examples shown in Fig. 3 of Fishman patent, need tangible center relief groove in each bevelled wall spare, this can must weaken these wall spares.To should be mentioned that also in the Fishman container, the vertical wall spare that replaces of the container that opens wide keeps their vertical orientations perpendicular to substrate wall when shrinking.Thereby obviously, the Fishman container can not be the contraction state injection molding, and is the molded method of contraction state owing to very economical aspect die production and molding process, so very favourable from commercial operation.

Summary of the invention

A main purpose of the present invention provides a kind of collapsible container, this container is opened or deployed condition is or forms the container of a substantially rigid at it, and when a suitable lid or sealing member card were joined thereon, this container can provide an actual available watertight storage container that for example is used for suitable food or similar articles.This container is very convenient, and for the food of " prepare just with " provides a kind of solution of carrying of particularly suitable people's needs, such as be used to picnic, people's that those lunches with them take the working space to lunch and other occasion that need temporarily store.The contractile character of container, promptly be retractable into a form highly minimum, that compress fully basically, especially have a sealing member mounted thereto, in being enclosed in order to any residue in the container that will vacate at that time, used container can be deposited or be collected in the hamper or similar object of " brown sack ", knapsack, picnic usefulness, for cleaning subsequently and repeated usage.

Also be to provide a kind of method that is molded this container of contraction state from the further again main purpose of the present invention, with as the measure that realizes the maximum economic benefit in molding equipment and the process, and a kind of compact conformation is provided but still can be launched into the moulded product of the self-supporting state of relative rigidity fully.

A significant aspect of container of the present invention is that it can step by step, next wall section fold and opens, and can changing the volume of container, and simultaneously himself is remained on any folding step by step state.

Other feature of being wanted of the present invention comprises: provide a kind of and can wash the container that also can be stacked in the mode identical with traditional plate in the dish-washing machine in dish-washing machine with its folded state, provide a kind of and stay open in use and keep the container of closing, and provide a kind of and make when being contained in the shipping case and utilize space maximized container when storing at home in when storage.

In order to realize improvement of the present invention and very practical container, the invention provides a kind of like this collapsible container, this container comprises a substrate, one apical ring and peripherally be fixed on described substrate and the apical ring and at a wall that extends between the two, described container can apical ring from described substrate make progress spaced apart and form a deployed condition of an internal tank and described apical ring with outwards spaced apart, basic and described substrate is concentric relation ground and regulates around between the contraction state of described substrate, described wall comprises and extending upward and peripherally continuous a plurality of wall sections, at described unrolling of container state, the relative internal tank of described wall section alternately outwards and slope inwardly, contraction state at described container, described wall section is folded in over each other, and be received in substantially with one heart between substrate and the apical ring, and the wall section is surrounded substrate, surrounded by described apical ring again, wherein, container comprises the bending area that connects the adjacent wall section, the relative bending area of adjacent wall section has limited flexibility, and wherein, but each bending area independent operation, move between second state of nature of closing that folds with first state of nature of opening launched in corresponding adjacent wall section and corresponding adjacent wall section, by this, container just can be adjusted to fixing between described expanded position and described punctured position, the position that part is launched.

According to said structure, in the substrate of a substantially rigid and be suitable for admitting the container perimeter wall that extends between the apical ring of a substantially rigid to comprise one group of ring or the continuous wall section of periphery of rigidity substantially, these wall sections are connected with adjacent wall section at fixing annular top place, and the connecting portion in interior and the outside is alternately pointed in the inside that forms relative container.Be provided with comparatively flexible annular section between these wall sections.In unrolling of container or open mode, the inside of the relative container of all wall sections self is alternately inside and outward-dipping with relative vertical direction, and sequentially makes progress from substrate to apical ring, and each wall section radially or peripherally increases than substrate substantially gradually.So the structure of the expansion container that forms will be inverted taper shape, and all wall sections upwards substantially outwards become step-like from substrate.This makes the wall section can directly be shrunk to one heart around substrate again downwards, and apical ring is around the folded wall section of shrinking.

Wall section reality relative to each other is folding to be occurred in the sweep, this sweep between the wall section, each wall section and tight adjacent wall section or all wall section bonded assemblys one apex zone place, and the thickness of this sweep is than the thin thickness of the wall section of its each side.Thicker part is all than sweep rigidity more, and has obviously the more flexibility of limitation.At the unrolling of container state, thin part forms the arc extendible portion than the heavy wall section, forms a circular arc greater than 90 degree, and, before in the contraction process of container, moving past on the center substantially, provide sizable rigidity for the wall section along the height of entire container wall.When applying positive substantial power when shrinking apical ring and substrate toward each other, flexible portion between the wall section will be with the mode of the flexibility hinge direction side-bend along fold, such bending provides actual folding, and makes the wall section be minimum in any trend of wanting side-bend or motion when shrinking each other simultaneously.By thin formed each bending area of part along its each edge by adjacent delimiting than the heavy wall section.In case the circular arc of bending area is reduced to less than 90 degree, the center of moving just overcome the proper drag that bending area moves, and the zone of this contraction is the dome-shaped form less than 90 degree.From close to open mode or oppositely directed motion, each bending area reverses and distortion slightly, till it overcomes its stabilized conditions and is turned to other state.

Molded container according to contraction of the present invention is as follows: relative rigid walls portion defines leg-of-mutton clearance space substantially, and this space forms by open about 8 ° of two walls to about 40 ° scope from vertical direction.But, owing to will become clear below, a preferable scope is from about 10 ° to about 16 °.

Launching container from its contraction state will push downwards or pulling in substrate when substrate moves up at apical ring.When sweep launched and move into circular arc greater than 90 degree, wall can trend towards the rigidity that becomes, and effectively container is pinned at open position.

When hereinafter structure of the present invention and details being described more intactly, will mention other features, objects and advantages of the present invention.

The specific embodiment

In the accompanying drawings, come the feature of the embodiment shown in the sign picture 1-11 with two numbering.Feature among the embodiment shown in Figure 12-22 is with indicating with last 1 same numeral as prefix.

Now please more specifically referring to accompanying drawing, collapsible container 10 comprises a substrate 12, an apical ring 14 and a folded wall 16 of extending betwixt.Substrate 12 is members of a substantially rigid, and this member comprises a bottom 18, and this bottom 18 comprises the upright substrate wall 20 of a periphery.This substrate can be straight, and comprises that preferably one of any suitable shape (as dome) is positioned at the area pressed center, upwardly extending slightly or projection 24, and is to help launching container, such as will be described later.This substrate also preferably has from one group of sagging little leg of the bottom 18 of substrate, and these legs form spherical protrusion 26 or continuous leg flank (not shown).

Apical ring 14 comprises a continuous or annular ring wall 28, and this ring wall 28 has the flange 30 of the horizontal directed outside of a periphery at medium altitude place roughly.Similar to substrate 12, apical ring 14 is rigidity substantially, and has diameter or other the non-circular cross-sectional area bigger than substrate 12, in the contraction state of container, to surround substrate, as shown in Figure 4, and enough outside from substrate, to hold folding wall of container betwixt.Apical ring flange 30 provides additional lateral rigidity for apical ring, and for particularly when bowl is filled thing, moving the measure that bowl is provided convenience and used.In addition, in the time will opening the bowl of contraction, ring flange 30 makes the user easily will point around flange 30 and the below, and simultaneously with on the dome area pressed 24 that is pressed in substrate under the thumb, vertically launches relative to each other to force substrate and apical ring.As the another kind of form of pushing on 24 in the zone, particularly for bigger bowl, can be around the bottom 18 of substrate, exert pressure around the adjacent vicinity of its substrate wall 20 at periphery.As described and will the most clearly mention in Fig. 1 and 2, ring flange 30 can stretch out slightly or enlarge to form grasping member 32 at radially relative part place.

Coming molded substrate and apical ring as the entity that separates with wall is a preferable method of moulding, and this method is by utilizing rigidity and/or flexible poly-mer in various degree, and the rigidity of obviously bigger relative wall section can be provided to these members.

Container side wall 16 is formed by the continuous wall spare or the wall section 34 of one group of annular or periphery, lower wall section surround and closely in conjunction with (such as in many members molding process, self combining closely) on the bearing shoulder 21 of on the wall 20 of the substrate 12 and bottom that is placed in substrate above slightly.

In the embodiment of Fig. 5 A, integrally be combined on the thin base part that upwards protrudes out 22 than all the other wall sections the most following little or base wall section on it highly slightly, when wall of container is folding, this base part 22 will form a bending area between this lower wall section and substrate.

From the joint of lower wall section and substrate upwards, the inside of wall section 34 relative containers and vertical direction alternately outwards and slope inwardly, and each wall section is on the top of alternately pointing to outer and inner side or form respectively as the top ends office of the total corner connection portion that is shown in 36 and 38 places is connected to adjacent ground wall section above it.

Please note Fig. 5, go up most or wall section 34 is connected to a neck ring 37 of pointing to upside by a sweep that this neck ring is for example admitted and closely is fixed in the bottom of ring wall 28 in the mode that this foot is advised.In the embodiment of Fig. 5 A and 6A, the lower edge of upper wall section 34 and apical ring 14 partly be one or otherwise closely periphery couple together.

Please note the container of opening, alternately each the wall section in the bevelled wall section has a preset thickness, and has the more limited flexibility of the bending area that connects adjacent wall section 34 or part 40.Sweep 40 than wall section 34 want relative thin some, and its thickness is substantially equal to the thickness of the extendible portion 22 of the substrate among Fig. 5 A.Bending area or the part 40 general corner connection portions 36 or 38 that between each wall section and adjacent with it adjacent wall section, form.As mentioned, the height of the part 40 that reduces of these thickness is significantly less than the height of wall section 34.Please pay close attention to Fig. 5 again, in unrolling of container or open mode, these sweeps 40 form extendible portion of the inside face of appropriate section 34 thereunder for outward-dipping wall section 34, and are the outside faces of respective wall section extendible portion for intilted wall section.When such formation, each side of these bending area parts 40 and bight thereof just define the direction of jackknife action naturally than the heavy wall section, the fold sequence that please pay special attention among Fig. 8 to be advised.What also will appreciate that is that before folding, the location in these zones 40 between bending area 40 and the adjacent wall section provides the stability of crossing center-point to a certain degree, collapses unintentionally to prevent wall 16.Only can just can overcome such stability by applying enough forward vertical pressure, force apical ring and substrate vertically to move towards one another, with the motion of crossing center-point that realizes bending area 40 and all zones jackknife action to " snap action " of contraction state.When the beginning jackknife action, each related bending area 40 slightly twists, and moves to the state that can be considered to cross center-point until it.By this way, the container oneself that just make container, particularly fills article in it is cut out or unexpected tendency of shrinking reduces to minimum.

As noticing in the accompanying drawings, at the contraction state of container, adjacent wall section 34 form on the contrary towards V-arrangement or leg-of-mutton opening.The line of centers of each V-arrangement opening is substantially perpendicular to the horizontal plane that shrinks container.This structure is allowing injection molding separately so that important meaning is arranged aspect the moulded parts demoulding.

Total possible range of the opening angle between the adjacent pinch wall section 34 is 8 ° to 40 °, and preferable scope is 10 ° to 16 °.Realizing container in the rigidity under the open mode and contraction or launch aspect the balance of being wanted between the required power of container, 10 ° angle is considered to optimum.As very actual thing, this angle also is considered to make the moulded parts can be from the minimum angles of the mould demoulding consistently.As will giving understanding, when angle increased, the rigidity of opening container just reduced.

Please special concern Fig. 7-9, as seen from the figure, if necessary, can be by exerting pressure with centering on containers sequentially, perhaps by rotary container when exerting pressure, with on wall section 34, produce one step by step or ratchet engagement (ratchet) effect help open and shrink container, and and non-once each bending area of engaging location fully just.

Fig. 9 is focussed in particular on and illustrates when wanting or require less volume by partially folded or launch for the container that uses.Under such state, container has the function of admittance and storage food or similar articles fully, and, as among Fig. 3 open in the container, sealing member 42 also can play effect fully, and this is because the size of apical ring all is stable under each state of container.

Please pay special attention to Fig. 3, can see, all wall sections form the inverted cone shape of a cardinal principle step by step from the cardinal principle that substrate to apical ring makes progress to the external container of opening.

Please note Fig. 7-9 again, when vertically shrinking container, bending area 40 is folded between the adjacent wall section, is the shape of dome substantially.Therefore, adjacent wall section is folded into and makes the thicker main height part of wall section concentric abreast substantially relative to each other, and the angle between the adjacent wall section preferably is roughly 10 ° to 16 °, and all wall sections side direction between substrate wall 20 and apical ring wall 28 is alignd and around described substrate.This can see the most clearly in the cross sectional detail of Fig. 6.

Please note Fig. 3,9 and 10, can see that sealing member 42 can be fitted on the apical ring 14 with the suitable manner card under any state that container presented.For the ease of such joint, the top of apical ring wall 28 can be outward-dipping slightly on peripheral flange, in the groove with the sensing downside that is received in the sealing member upper peripheral edge.Be appreciated that, because under any state of container, folding wall section is concentrically positioned in apical ring 14 inboards of substantially rigid, so sealing member 42 can be used as the suitable cover closing member of the container of container, container of opening that partly launches and the contraction that realizes compact storage state.

As previously mentioned, in the time will opening container before use, people only need to engage finger around the periphery flange 30 of apical ring, and push in the bottom with one or two thumb and to apply downward pressure on the projection 24 and get final product.Perhaps, can be in the bottom from sequentially exerting pressure around its periphery on one's body.In addition, as shown in figure 11, a cross bar 44 is set with can the diagonal angle crossing the recessed recess that in the lower surface of bottom 18, forms by projection or recess, rather than relies on the direct pressure on projection 24 or the bottom 18.User's finger can be caught this cross bar 44 really, with directly pulling downwards in the substrate of container, makes the relative apical ring of substrate move down and launch Zhu Biduan.

Please again referring to Fig. 6, to should be mentioned that, the restriction that folded wall section 34 will be shunk downwards as the relative substrate wall with apical ring of remaining wall section, make the formed supporting plane in bottom that all wall sections and apical ring remain on substrate with and on the top slightly of support foot, thereby to the supporting of the container under the two states that launches and shrink all on substrate and substrate leg, rather than on the bending area of Bao Deduo.

Now please in further detail referring to the embodiment shown in Figure 12-22, those members of the basic building block of this embodiment and previous embodiment are basic identical, thereby, indicate with the same numeral that has prefix 1.Therefore, container 110 comprises a substrate 112, an apical ring 114 and a folded wall 116 that is made of the rigid walls section 134 that replaces and bending area or part 140.

As first embodiment, container 110 launches in aforesaid mode and shrinks, and is configured to make container can be under this state pratical and feasible and preferably carry out molded at punctured position.According to such requirement, wall section 134 contraction state form on the contrary towards the V-arrangement opening, the possible range of the angle between wherein all wall sections is 8 ° to 40 °, but preferably within 10 ° to 16 ° scope, and optimum angle is 10 °.The line of centers of each V-arrangement opening is from open wall section 34 formed summits, extend perpendicular to the horizontal plane of the container that shrinks.In unrolling of container or open mode, both relative to each other with greater than 90 ° angle tilt, the defined vertical direction of the vertical line of substrate tilted wall section 134 relatively again.

For the folding of reinforced wall section 134 with launch action, each wall section 134 along its edge as 135 places, forming the oblique angle, so that the gradually transition of wall section 134 between adjacent sweep 140 to be provided.This with as different in very precipitous transitional region as shown in Fig. 5 and 6, first embodiment.

As first embodiment, in the open position of container, sweep 140 for lean-out shown in Figure 16 to wall section 134 form extendible portion of inside face of the respective wall section 134 of its below.Similarly, sweep 140 is outside faces of respective wall section 134 for intilted wall section 134 extendible portion.As previously mentioned, this relation will help to limit the direction of jackknife action inherently, please pay special attention among Figure 19 and the fold sequence of being advised among aforesaid Fig. 8.

Especially referring to Figure 16 and 17, can see that please the wall section of the aspect ratio of base wall section 134 on it is high, and extend the whole height of the upright substrate wall 120 of periphery.The lower end of this wall section 134 under is folded under the bottom 118 of substrate 112, and is bonded on one and admits in the recess 119, thereby has formed the part on support of vessel plane effectively.Such as will be appreciated, being connected therebetween strengthened in the overlapping region of the reinforcement between wall of container bottom and the substrate.

Realize engaging of wall of container and apical ring by a neck ring 137 of pointing to side direction, this neck ring is connected to the wall section 134 that goes up most by the sweep of going up most 140.Neck ring 137 comprises that on its outer rim one points to the locking crimping 139 of upside, and neck ring 137 and crimping 139 boths are received in the substrate of annular wall 128 in the formed corresponding locking recess.Apical ring 114 comprises the ring flange that outwards protrudes out 130 of holistic annular as aforesaid ring 14, and this flange 130 is both for apical ring provides lateral rigidity, again for operating and using this bowl that a convenient measure of using is provided.As the measure of being convenient to the grasping flange, suggestion is provided with holistic sagging grasping crimping 131 around the periphery of the peripheral edge portion of flange 130.

Last difference between in the various cutaway views of Figure 12 and container 110, can seeing among two embodiment.As from these figure with will understanding after the figure of first embodiment compares, substrate 112 comprises a upwardly extending center area pressed or a projection 124 that obviously increases.This has strengthened particularly can will opening the zone that pressure is applied thereto, and helps the operation of container, and helps simultaneously further to strengthen otherwise will be straight bottom 118.As shown in Figure 22, bottom pushing projection 124 also can be provided with the cross bar 144 at a diagonal angle, is used for the purpose of being mentioned when cross bar 44 is discussed in the front.

Also have, as described in about first embodiment, can be provided with and to block a suitable sealing member 142 that fits on the apical ring 114.Consider the contraction of folded wall section with one heart and open the mode of container, no matter this container is to open fully, shrink fully or part is launched, and such sealing member all can form a suitable cover closing member of container.

Please especially referring to Figure 21, can see, downwards the wall section 134 of shrinking, more particularly be meant the top slightly that remains on the bottom of substrate and/or the supporting plane that support foot limited to the sweep 140 of downside, thereby more stable supporting is provided, and avoids obvious thinner bending area to contact with area supported.

Vessel Design as described becomes to utilize the structure of bending area " network ".This is not a kind of the stretching as spring with the shape of the concertina that opens and closes, but a kind of flat storage container that can open and close based on " subsystem (opposingangle) " principle.

In known expansion container, generally be to come molded container with the form of opening or launch.Thereby open mode is the state of nature of those containers, that is to say, those containers " would rather " stay open but not any other state.Therefore, when people tried folding or shrink these containers, these containers tended to rebound and open, and just get back to their state of nature.Container of the present invention then is not such situation, and in the present invention, container preferably is state flat or that shrink and comes molded.This is its initial natural state, just means that also this container would rather keep its this closing state at the very start.At the network internal storage of bending area at a plurality of folds.In an illustrated embodiment, but be provided with the zone (if necessary, can add more group, to increase volume) of three groups of independent operations.As seen in fig. 9, but the bending area of each independent operation has one second " nature " or quiescence when opening, and in this state, fold rather stays open and be uncorrelated with remaining fold.In this structure, the action of the contractive action of container and expansion container all needs to operate individually these folds.Fold and launch this container and all need positive action.This can be called as " subsystem " principle.The angle of fold keeps fold to close in off position; The angle of fold keeps fold to open in open mode.In order to move to open mode, otherwise perhaps, slightly reverse or twist sweep, overcome subsystem, turn to the form of another state then until it from closed condition.Because the diameter of bending area is unalterable, so can produce such action.Fold does not have other intermediateness.It or open or close, perhaps reversed (side is opened and opposite side is closed).In this structure, it is semi-open and keep the situation of available space simultaneously for example single wall section one to occur.As previously mentioned, a kind of easy mode of operation bending area is to make container " ratchet engagement ", once the state of extremely partially or completely opening in a side " ratchet engagement ".

Particular structure of the present invention can closed or contraction state keeps flat container, and keeps launching at any state of opening or partially opening.Because bending area has two " nature " states,, and would rather stay open upon deployment so container would rather keep cutting out when contraction is flat.Because the bending area in the operational network has fixing partial volume so this container can be opened into because it would rather stay open in the form that partially opens independently.Aspect storage space in making refrigerator and the dish-washing machine maximum storage space and optimization when washing, this is valuable especially.

Collapsible container of the present invention is described as being made by a kind of molded plastics (that is man-made polymer) in preferred embodiment, and has all " entity that separates " that comprises substrate, apical ring and folded wall.In a preferable method of moulding, all " entity of separation " for example can be realized by the molding equipment that utilizes multistage ground of energy molded substrate, apical ring and folded wall, and can select the poly-mer of the different brackets of substantially rigid and/or cardinal principle rigidity in this equipment.This can also change the color or the penetrability of substrate, apical ring and folded wall.

Be appreciated that container of the present invention can be molded as an integral structure in the single molded step basically as described in conjunction with the embodiment of Fig. 5 A and 6A.In addition, also can be in single mode system step, realize that by the suitable thickness of selecting several portions substrate and apical ring compare in relative rigidity or substantially but the described preferable difference aspect the rigidity of inflexibility with folded wall.A kind of like this molding equipment also might be provided, and wherein mold structure becomes the poly-mer with different-stiffness or flexible grade that is provided for substrate, apical ring and wall to institute's favored area of mould inside.

Be appreciated that, be suitable for mould in contraction state injection molding wall portion and require a plurality of concentric annular, interlaced, the mould parts of triangularity or V-arrangement substantially, these mould parts are loaded on the mold half, and corresponding to the quantity that is folded in Zhu Biduan over each other.

Foregoingly should be considered to explanation of the principles of the present invention.Because those those skilled in the art that can be susceptible to various modifications and change, so shown in not wanting the present invention is confined to and described these structures and mode.And opposite, modification modification that all are suitable and equivalent all are considered to fall within the scope of the present invention for required protection.
