But, will recognize from following description, embodiments of the invention described herein can be used in the container of commercial environment. In addition, it will also be recognized that, the container that the aspect of the present invention described relative to the disclosed embodiments can be expanded to various sizes and shape, and it is not limited to specific dimensions and the shape of the container of institute's diagram herein and description.

Container 100 generally includes container lid 102 and container body 104. Container lid 102 be formed as single type (entirety) structure with container body 104 and be not formed as multiple points liftoff be attached to together with parts.

Container lid 102 is attached on container body 104 by hinges (hinged part) 106. Hinges 106 allows container lid 102 between open and closed positions relative to container body 104 pivotable, forever is fixed on container body 104 by lid 102 simultaneously. In open position (Fig. 1), it is possible to access is stored in the content of container 100 inside. In a preferred embodiment, container lid 102 seals relative to container body 104 in off-position (Fig. 2).

In addition, container lid 102 forever is attached on container body 104 by hinges 106, can not lose container lid 102 or to be shifted from container body 104. This prevent the problem of lid 102 repeats lost often occurring in and not being attached on container body 104 forever in closet or cabinet.

Container body 104 generally includes the body part of cup-shaped, and this body part generally includes the sidewall sections 110 of the general toroidal upwards extended from bottom 112, thus forms the body part of described cup-shaped. The body part of cup-shaped is the part of the article usually keeping being stored in container 100. Sidewall sections 110 and the bottom 112 of annular are generally formed as one-piece unitary structure by injection-molded and container lid 102. Thus, whole container 100 is from one piece, and is mutually snapped into together with being not separated (independence) or is secured together multiple parts. The polypropylene that whole container 100 is preferably crossed by purification (clarification) is formed.

See Fig. 1 and 3, container body 104 comprises the top flange 114 of radial extension, and this top flange 114 has top surface 116, and when container lid 102 is in the closed position, the basal surface 120 of container lid 102 is seated against on this top surface 116. The region 121 that the radial top flange 114 extended limits with the device for clamping being illustrated as the lock that extends radially inwardly only section (section of holding) 122 interacts, is fixed on off-position for by container lid 102. In a preferred embodiment, when container 100 is in an open position and during off-position, the top surface 116 of flange 114 is in plane shape (or smooth).

Although the cross section of annular side wall portion 110 is in the form of a substantially rectangular, but extension roughly radially outwards arcuately bends the transverse side 123,125 put between rear side and face, front side 127,129.But, other designs may use roughly straight side. Adjacent side is connected by the turning in fillet. In a preferred embodiment, top flange 114 exceedes outwardly stretching out between about 0.050 and 0.070 inch and preferred size between about 0.055 and 0.065 inch of adjacent side 123,125,127,129.

In addition, side 123,125,127,129 is mutually outwards tapered when moving away from bottom 112. This taper is generally between about 91 degree and 100 degree and the most typically between about 94 degree and 98 degree. The outside surface repairing round turning between adjacent side 123,125,127,129 comprise be formed at wherein to meeting portion, when by multiple container stacking to time together, should to the portion that connects to the top surface 116 connecing second container body 104. This prevents the container body of stacking from pinning mutually.

Container lid 102 comprises main body 130, and this main body 130 covers the opening end of annular sidewall 110, with closing containers 100. Main body 130 provides the basal surface 120 of the top surface 116 of seating top flange 114. In certain embodiments, container lid 102 by so retainer shaft to being pressed against top flange 114, to provide shoulder seal between top surface 116 and basal surface 120.

Container 100 also comprises sealing flange 132. Sealing flange 132 can be looked at as a part for container lid 102. Sealing flange 132 is from main body 130 and more particularly axially extends from the basal surface 120 of main body 130.

Sealing flange 132 forms radial seal with the internal surface 136 of annular sidewall 110. Thus, sealing flange 132 is similarly general toroidal.

Sealing flange 132 is preferably wedge shape, so that it has wider base part 137 near main body 130 place and is having narrower distal tip part 138 in the position away from interval, main body 130 axial ground. The angle that the radially-outer surface 140 of sealing flange 132 is preferably spent between 100 (100) degree with about 90 (90) relative to basal surface 120 tilts. More preferably, described angle is between about 92 (92) and 95 (95) degree. This tilt relationship allows more easily to be inserted in annular sidewall 110 by sealing flange 132 between the closed-down period of container lid 102.

The angle that internal surface 141 is preferably spent between 100 (100) degree with about 90 (90) relative to basal surface 120 tilts. More preferably, this angle is between about 90 (90) and 93 (93) degree, and is preferably about 91 (91) degree.

Sealing flange 132 preferably has the width between about 0.030 and 0.045 (basal surface 120 being parallel to main body 130 records) at base part 137 place and has the width between about 0.020 inch and 0.030 inch at tip portion 138 place of far-end. In a preferred embodiment, the height H 1 of sealing flange 132 is in the whole circumferentially substantially constant (that is, along all sides of container lid 102) of ring-type sealing flange 132. Preferably, height H 1 between about 0.225 inch and 0.325 inch, and more preferably between about 0.250 inch and about 0.285 inch.

The wall thickness T 1 of main part is preferred between about 0.058 and 0.070 inch, and more preferably between about 0.060 and 0.067 inch.

Container lid 102 also comprises strengthens skirt section 170. Strengthen skirt section 170 axially to extend away from main body 130 and be radially outward in the spaced relationship of constant from sealing flange 132. Strengthen at least partially extension of skirt section 170 along three sides of container lid 102.Strengthen the rigidity that skirt section 170 increases container lid 102. In a closed position, strengthen skirt section 170 be radially positioned at the outside of top flange 114 of container body 104 and suspend downwards with a part of crossover of the adjacent side of container body 104.

Sealing flange 132 and reinforcement skirt section 170 form reception channel 172 between which. The top of the annular sidewall 110 of reception channel 172 axial ground receiving vessel body 104. More particularly, when container is in the closed position, a part for the top flange 114 of the side 123,125 and 129 of its receiving vessel body 104.

The salient that the section of holding 122 extends internally with being formed as the inner surface radial direction from reinforcement skirt section 160 or protruding head (see Fig. 1).

Main body 130 comprises the seat part 143 being radially in sealing flange 132 and strengthening between skirt section 170. Seat part 143 forms the bottom of reception channel 172. The shape of this part of main body and structure are constructed to the sealing promoting container lid 102 to the improvement of container body 104, as will be described further.

Container lid 102 is configured to container body 104 and provides the sealing and seating that improve. The applicant of the application it has been determined that when using fastener (snap ring) as the present invention or container lid is fixed on container body by device for clamping produced problem. When fastener or device for clamping are in side middle, the turning of lid trends towards disengaging from container body, thus forms leakage paths. In addition, in certain embodiments, when the front side that claw or fastener are only in lid (namely, the side contrary with hinges) upper time, then lid may axially bend song away from the transverse side extended between face, front side and rear side so that container lid can not the top surface of transverse side described in seating well. The sealing that the present invention has been constructed to improve between container lid 102 and container body 104 and seating, to provide water-stop, as now by illustrating in an embodiment. As used herein, when container can be filled water, reverse and be shelved on container lid 102 placement and container 100 does not leak water, it provides water-stop.

The main body 130 of the present invention is bent in advance when container lid is in an open position. But, when container 102 is in the closed position, main body 130 is substantially in plane shape. From this in advance part of bending configuration transitions to be the special part of the main body of plane shape configuration substantially be main body of contiguous sealing flange 132 and the seat part 143 of at least outside being radially positioned at sealing flange 132 of main body 130, in a closed position, it axially is biased on the top surface 114 of container body 104. It is noted that allow produce some deviations from complete plane shape, but, in a closed position, this part 143 will at least in an open position than it time more smooth.

Therefore, when container lid 102 is transformed into complete off-position (see Fig. 2) from fully open position (see Fig. 1 and 3), container lid 102 and particularly its relevant part can be seen as the layout that " expansion " becomes more plane.

Describe below with reference to Fig. 4-8 pre-bending (part) of front part 144. Because strengthening skirt section 170 to have from the constant height H 2(of seat part 143 see Fig. 4), so the bending of far-end strengthening skirt section 170 will follow the bending of a part 143. In addition, can find out when each distance D2 of seat part with reference plane 153 is compared bending (degree) of a part 143.By being parallel to hinges but pass the base part 137 of sealing flange 132 and the plane definition reference plane 153 of the point of intersection of seat part 143. In addition, described plane comprises 2 points of the midpoint of the front part 144 of a part 143 and the rear portion of seat part 143. In fig. 12, described point is all positioned on line 5-5.

Seat part 143 bends in advance with the direction of two separation. The front part 144 of curved body 130 like this so that corner part 146,148 relative to next-door neighbour holding part 122 centre portions 150 straight up. It is the relative terms used based on the orientation in container lid 102 Fig. 1 and 2 in an open position straight up. In the figure 7, the diagram at turning 146,148 is downward, but, relative to Fig. 1 and 2, lid 102 is illustrated as in the closed position. But, as seen from Fig. 7, when moving to another side from the side of container lid 102, the front portion of container lid 102 is change relative to reference plane 153.

In the configuration, when extending laterally to another corner part 148 from side to another side from a corner part 146, the seat part 143 of basal surface 120 is roughly recessed into. When container lid 102 is in the closed position relative to container body 104, this recessed profile causes two corner parts 146,148 to be biased in the respective corners position of top surface 116 of container body 104. The holding part 122 of container lid 102 provides reactive force that the curved part of container lid 102 is biased in top surface 116.

This crooked outline can also be seen in Figure 5, wherein the top surface 152 of visible body 130 from the sectional side view (see Fig. 8) of container lid 102.

In the structure shown here, when blocking the top flange 114 closing radial extension when holding part 122 so that container lid 102 is fixed on off-position, after corner part 146,148 contacts top surface 116, the centre portions 150 of main body 130 pulled down on the top surface 116 of container body 104. Corner part 146,148 is biased in top surface 116 by this, causes corner part 146,148 to bend relative to centre portions 150, so that the seat part 143 of front part 144 becomes more smooth.

The seat part 143 of the rear portion 156 of container lid has similar recessed profile, but degree is less. Directly the part of the seat part 143 of adjacent hinges 106 is substantially straight. Only corner part 158,160 is bent, thus provides the female shape.

Particularly see Fig. 8, not only the front part 144 of container lid 102 and rear portion 156 extend to another cross side and bend from a cross side, and container lid 102 and more particularly main body 130 is in open position from rear portion 156(namely, near rear corner 158,160 and hinges 106) it is bent to front part 144(in advance namely, near front corners 146,148). This is bending is protrude, that is, bending contrary with from side to another side. More particularly, when being converted to rear corner 158,160 from a front corners 146,148 on same transverse side, top surface 152 is (invaginated type) that be roughly recessed into, and the basal surface formed by seat part 143 is (convex shape) that roughly protrude. In addition, this recessed form is at least positioned at from the part of the radially outer top surface of sealing flange 132.

In a closed position, this bending middle part (see Fig. 9) axially seating top surface 116 assisting to maintain container lid 102 and the more particularly widthwise side portions 162,164 of main body 130.

When container lid 102 is closed relative to container body 104, the middle part of widthwise side portions 162,164 will before corner part 144,146 seating top surface 116. Therefore, the middle portion of widthwise side portions 162,164 contacted top surface 116 before engaging the radial top flange 114 extended at holding part 122. When container lid 102 is closed, it can almost be seen as container lid 102 " expansion ".

Figure 10 illustrates when container lid starts to close that it is in the state of opening. Figure 10 illustrates when seat part 143 starts to be shelved on the top surface 116 of top flange 114 near hinges 106. When container lid 102 is closed relative to container body 104, first the rear portion of container lid will contact with container body 104. This is illustrated as the top surface 116 that the front part 144 when container lid 102 leaves top flange 114 in Fig. 10 and lifts, and the rear portion 156 of container lid axially is pressed in top surface 116 simultaneously. In an embodiment, when the rear portion seating top surface 116 of the contiguous hinges 106 of seat part 143, the angle [alpha] that container lid 102 will be opened between about 5 and 20 degree. The theoretical planes 153 that the intersection point of the mid point 150 of the front part 144 at the top surface 116 of this angle [alpha] in top flange 114 and the pedestal 137 of sealing flange 132 by contiguous hinges and pedestal 137 place of sealing flange 132 limits limits.

It may be seen that the curved part being formed in container lid 102 (curve) be combined in all positions and particularly directly the position of contiguous one or more holding part 122 by the seating of the improvement that promotes the seat part 143 of basal surface 120 on top surface 116.

For the sake of completeness, other embodiments can use holding part at the different positions place of such as turning (that is, turning 146,148 instead of middle portion 150). In this case, anterior curved part is so contrary, so that the top of middle portion contacting container body before there is the part of holding part. This is because use holding part to pull turning downwards after the freedom part of container lid is biased in the top of container body 104.

In a word, it can be seen that embodiments of the invention relate to the main body of pre-bending container lid, so that not being close to the top surface of part contacting container body before the main body near holding part is biased on top surface of device for clamping. This causes the axial seating of the improvement of the basal surface of the main body of container lid on container body.

Namely the further feature of embodiments of the invention relates to adjacent side face part 162,164(, front part 144 between respective corners 146,158 and 148,160 and the part extended between rear portion 156) bow song (bending) lateral parts of part of sealing flange 132. Bent sealing flange is radially outward bent by having, when main body 130 and thus sealing flange 132 becomes at ordinary times closing between working life, the bent lateral parts of the bow of sealing flange 132 incites somebody to action radially deform outward, to force the internal surface of the side 123,125 of the annular sidewall 110 of itself and container body 104 to carry out the joint strengthened. By having the sealing flange 132 that radially outwards bow is bent, the structure of sealing flange is previously determined at the deformation direction closing the described part of sealing flange 132 between working life.

In an embodiment, when container lid 102 is transformed into off-position from open position, to the centre portions 180,182 of the side (see Fig. 4 and 13) put by remotely radial offset mutually.In an embodiment, if being switched to open position container lid 102 is in the annular wall 110 not being installed to container body 104, then the distance D recorded at mid point 180,182 place of side 162,164 will increase about 0.001% to 0.01%. In an embodiment, the value that distance D increases is between about 0.005 and 0.020 inch. But, depending on the length of lateral parts 162,164, the absolute magnitude being radially bent outwardly will change. Particularly, the deviation amount of distance D may change according to the size of container and angle [alpha] as above.

In a particular embodiment, all parts of sealing flange in the same side of reference plane 153 or are included in reference plane 153.

Container lid 102 and container body 104 comprise the stacking passage of the stacking for promoting container 100 when it is in closing condition. Other embodiments can not comprise described feature.

Turning now to Figure 15-24, illustrate another embodiment of container 100. In this embodiment, container 100 comprises at least one and preferred multiple projection of claw 202 form in arranging along skirt section 170. Claw 202 provides additional sealing integrity (see Fig. 1) by flexibly engaging the top flange 114 of radial extension between container lid 102 and container body 104. In addition, and describing in further detail as following, claw 202 also allows container 102 to keep local to open by general control mode, for ventilation and other objects.

See Figure 15, claw 202 is arranged around medullary ray 200 symmetry. In the embodiment shown, skirt section 170 arranges six claws 202. But, recognize, it is possible to less or more claw 202 is set. In addition, claw 202 can be set in an asymmetrical fashion around skirt section 170 in other embodiments.

Turning now to Figure 16, claw 202 radially-inwardly extend into the reception channel 172 being formed between skirt section 170 and sealing flange 132 from the internal surface 204 in skirt section 170. As illustrated, claw 202 is generally dome-type, however, it is contemplated that other structures, such as fin, pits rampway structure etc.

Referring now to Figure 17, each claw 202 is located along internal surface 204, so that its far-end 206 that is usual and skirt section 170 separates, as shown in the figure. It will be appreciated, however, that in other embodiments, claw 202 can be positioned at different positions place along internal surface 204.

Turning now to Figure 18, when claw 202 be positioned at as shown in figure flange 114 above time, lid 102 can be freely mobile relative to container body 104. But, it is possible to optionally some in multiple claw 202 are positioned at above flange 114, and some other in multiple claw is positioned at below flange 114, partly to open container 100. In described structure, lid 102 is partly retrained relative to body 104.

When lid 102 moves along direction 208, it is positioned at the claw 202 above flange 114 and contacts with each other. See Figure 19, once described claw 202 contacts flange, then skirt section 170 flexibly will radially bend away from flange 114, to allow lid 102 and particularly claw 202 is axially mobile relative to flange 114. See Figure 20, once claw 202 moves by flange 114, then seat 143 will contact the top surface 116 of flange 114 as shown in figure, and skirt section 170 will flexibly return its original configuration. As shown in figure 20, when claw 202 is positioned at below flange 114, there is small gap 212 between which.Recognizing, in other embodiments, gap 212 may be bigger, or is ignored completely, so that claw 202 is shelved on the basal surface of flange 114.

In addition, when move under the flange by face for claw 202, the form buckleing sound with card provides tangibly and the response that can hear. This response provides claw 202 and is positioned to the instruction below flange.

Figure 21-24 illustrates the various configurations of lid 102 relative to body 104. In figure 21, container 100 is shown in an open position. " open " and mean do not have claw 202 to be positioned in below flange 114. In the configuration, lid 102 can move freely relative to body 104.

In Figure 22 and 23, container 100 is shown as and is in mid-way. " centre " means that at least one claw 202 is positioned in below flange 114. Due to being arranged symmetrically with (see Figure 15) of claw 202, generally by the one of mutually opposing spaced relationship alignment, claw 202 is positioned at flange 114 above or below simultaneously. But, it is possible to optionally locate each claw 202 relative to flange 114 independently of one another with claw 202.

Special in Figure 23, only still it is positioned at above flange 114 near the claw 202 locking only section 122. This configuration partly opened is for needing the heated food being vented container 100 inside for heating to be desirable.

Turning now to Figure 24, container 100 is shown as to be in closes configuration. " closedown " means that all claws 202 are positioned in below flange 114. In the configuration, lid 102 and more particularly sealing flange 132(see Fig. 1) be all sealed on container body 104 as described above. The location of claw 202 reduces the container 104 that is sealed in being formed between lid 102 and body 104 and drops or possibility destroyed unintentionally in the event of load that is impacted.
