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

Sealing flange 132 and reinforcement skirt section 170 form receiving cable 172 between them.Receiving cable 172 is the top of the annular sidewall 110 of receiving vessel body 104 axially.More particularly, when container is in the closed position, the part of the side 123 of its receiving vessel body 104,125 and 129 top flange 114.

The section of holding 122 form from the inner surface radial direction of strengthening skirt section 160 the salient or the protruding head (referring to Fig. 1) that extend internally.

Main body 130 comprises the seat part 143 that radially is between sealing flange 132 and the reinforcement skirt section 170.Seat part 143 forms the bottom of receiving cable 172.The shape of this part of main body and structure are constructed to promote container lid 102 to the sealing of the improvement of vessel 104, and be such as will be described further.

Container lid 102 is configured to vessel 104 improved sealing and seating is provided.The application's applicant determined when use as the present invention engaging member (snap ring) or the problem of device for clamping appearance when being fixed to container lid on the vessel.When engaging member or device for clamping were in side middle, the turning of lid trended towards throwing off from vessel, thereby forms leakage paths.In addition, in certain embodiments, when front side that claw or engaging member only are in lid (namely, the side opposite with hinges) in the time of on, then lid may be away from the transverse side that extends between leading flank and trailing flank bow axially, so that the container lid top surface of the described transverse side of seating well.The present invention has been constructed to improve sealing and the seating between container lid 102 and the vessel 104, in order to water-stop is provided in one embodiment, as will illustrating now.As used herein, place and container 100 not during water leakage when container can be filled water, reverses and be shelved on the container lid 102, water-stop is provided.

Main body 130 of the present invention is prebended when container lid is shown in an open position.Yet when container 102 was in the closed position, it is plane that main body 130 is basically.Part and the seat part 143 of the outside that radially is positioned at sealing flange 132 of main body 130 at least of the main body of contiguous sealing flange 132 for the special part of the main body of plane configuration basically from this prebuckling configuration transitions, in off position, it axially is biased on the top surface 114 of vessel 104.It should be noted that to allow from complete some deviations of plane generation, yet, in off position, more smooth when this part 143 will be shown in an open position than it at least.

Therefore, when container lid 102 when (referring to Fig. 1 and 3) is transformed into complete off position (referring to Fig. 2) from the fully open position, container lid 102 and particularly its relevant portion can be regarded as " expansion " and are become the more layout on plane.

The below describes the prebuckling (part) of front part 144 with reference to Fig. 4-8.Have the constant altitude H2(of oneself seat part 143 referring to Fig. 4 because strengthen skirt section 170), so strengthen the bending that the bending of the far-end in skirt section 170 will be followed a part 143.In addition, when comparing, each distance B 2 to seat part and reference plane 153 can find out the bending (degree) of a part 143.By being parallel to hinges but pass the definition datum plane, plane 153 at the intersection point place of the base part 137 of sealing flange 132 and seat part 143.In addition, described plane comprises the front part 144 of a

part

143 and 2 points of the midpoint of the rear portion of seat part 143.In Figure 12, described point all is positioned on the line 5-5.

Seat part 143 is with the direction prebuckling of two separation.The front part 144 of curved body 130 like this is so that corner part 146,148 with respect to the core 150 that is close to holding part 122 straight up.Be based on straight up the employed relative terms in orientation among Fig. 1 and 2 that container lid 102 is shown in an open position.In Fig. 7, turning 146,148 diagram are downward, yet with respect to Fig. 1 and 2, lid 102 is illustrated as in the closed position.But as seeing from Fig. 7, when moving by side to opposite side from one of container lid 102, the front portion of container lid 102 changes with respect to reference plane 153.

In this configuration, the seat part 143 of basal surface 120 roughly is recessed into when extending laterally to another corner part 148 from a side to opposite side from a corner part 146.When container lid 102 was in the closed position with respect to vessel 104, this recessed profile caused two corner parts 146,148 to be biased in the respective corners position of top surface 116 of vessel 104.The holding part 122 of container lid 102 provides the sweep with container lid 102 to be biased into application force in the top surface 116.

Can also in Fig. 5, see this crooked outline, wherein the top surface 152 of visible body 130 from the sectional side view (referring to Fig. 8) of container lid 102.

In this structure, the top flange 114 of radially extending when holding part 122 engaging is when being fixed on off position with container lid 102, and the core 150 of main body 130 pulled down on the top surface 116 of vessel 104 after corner part 146,148 contact top surfaces 116.This is biased into corner part 146,148 in the top surface 116, causes corner part 146,148 with respect to core 150 bendings, 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 similarly recessed profile, but degree is less.Directly the part in abutting connection with the seat part 143 of hinges 106 is basically straight.Only corner part 158,160 is bent, thereby the female shape is provided.

Particularly referring to Fig. 8, not only the front part 144 of container lid 102 and rear portion 156 extend to another cross side and bending from a cross side, and container lid 102 and more especially main body 130 is at open position from rear portion 156(namely, near rear corner 158,160 and hinges 106) prebuckling to front part 144(namely, near front corners 146,148).This bending is protruded, that is, and and crooked opposite with from a side to opposite side.More particularly, when on same transverse side from a front corners 146,148 be converted to rear corner 158,160 the time, top surface 152 is (invaginated types) that roughly are recessed into, and is (convex shape) that roughly protrudes by the basal surface that seat part 143 forms.In addition, this recessed form is positioned at least on the part of sealing flange 132 radially outer top surfaces.

In off position, this bending assists to keep container lid 102 and widthwise side portions 162,164 middle part (referring to Fig. 9) the seating top surface 116 axially of main body 130 more especially.

When container lid 102 is closed with respect to vessel 104, widthwise side portions 162,164 middle part will be before corner part 144,146 seating top surface 116.Therefore, widthwise side portions 162,164 centre portion will be before holding part 122 engages the top flange 114 of radially extending contact top surface 116.When container lid 102 was closed, it can almost be seen as container lid 102 " does not launch ".
