Fig. 9 illustrates the release-push 32 in releasing position, as shown in Figure 2, by by being pressed on outstanding forward button part 114 with compression elastic piece 108, has made latch piece 32 slide in breech lock passage 52.The motion of latch piece has been shifted out breech lock protrusion 44 and the engaging of the collar 26.Compressed elastic component 108 on release-push 32, need lasting power to remain in illustrated position, because otherwise will make latch piece 32 move to backward latched position.

The diagram of Fig. 9 has only represented the position of a moment, due to breech lock 32 is discharged, makes compressed lid lifting protrusion 58 apply the power for opening and lid is shifted out to latched position on lid 28.In a preferred embodiment, the release of breech lock 32 makes when the power of compressed lid lifting protrusion 58 is released, and lid " (pop) upsprings " is to the position of slightly opening.In the position of slightly opening, breech lock protrusion 44 can not engage with collar opening again, thereby lid is not relocked.Then user can open to full open position of coupler by lid, so that food additive is added in container, or food is taken out from container.Lid 28 is promoted to the position of slightly opening makes user enough hands the lid of locking is released into open position.Thereby the restricted user of degree of flexibility can easily open container.

Insulation food storage container 20 can easily be closed.Food is being put into after container, and lid 28 is by towards off position pivotable.Or not lid applies the power for closing on 28, lid 28 is because lid promotes the position that protrusion 58 remains in non-locking.By the power applying for closing, with compression cover, promote protrusion 58 on lid 28, the taper edge 112 of breech lock protrusion 44 the card can equally with taper edge of the collar 26 along on slide, with by latch member 32 towards releasing position short distance (briefly) mobile.Downward power at lid on 28 makes after the snap close nose 112 on breech lock protrusion 44 crosses collar edge, and the compressive force on elastic component 108 pushes back latched position by latch member 32.The snap close nose 112 of breech lock protrusion 44 engages with the collar 26 and therefore covers 28 and closes lockedly.Lid 28 off position is pressed in the inside of packing ring 88 to cover on 28 central protrusion 40.

In the enlarged view of Figure 10, packing ring 88 is depicted as on the lower flange 100 that is arranged on throat 38.Packing ring 88 has outwards outstanding film 134, and this film 134 seals to form near the neck 124 of the inwall 120 of body 22, thereby prevents that food and liquid from escaping in the space between throat 38 and body 22.Packing ring 88 has inwardly outstanding film 136, this to outstanding film 136 contact with the central protrusion 40 of lid 28 between being in throat 38 and covering 28 with the neck at container sealing be provided.The food that food is maintained at container thus holds in center cavity, and by packing ring 88 Leakage preventions.Packing ring 88 illustrates with its contactless state in the accompanying drawings, although neck 124 is depicted as with packing ring 88 and contacts with inner protrusion 40.The film 134 of packing ring 88 will be out of shape when the neck with device contacts with inner protrusion with 135.

The second embodiment of food container 140 as disclosed in Figure 11 to Figure 18 is provided.In the second embodiment as shown in figure 11, except breech lock, food container 140 has the basic structure identical with the food container of the first embodiment.Lid 144 is fixed on to off position and allows user to open and cover 144 to obtain the contents of container 140 or the breech lock 142 that food is added into container 140 is configured to from covering 144 extensions in the second embodiment.The button 146 of breech lock 142 extends outwardly beyond the cylindrical wall 148 of covering 144, and the button of the first embodiment forms the extendible portion of the cylindrical wall of lid.In the cylindrical wall 152 of the collar 154, be also provided with the outshot 150 being positioned at below breech lock.Wire loop 156 extends and extends to the top of the outshot of button 146 from the outshot 150 of the collar 154.Salient rib shape portion 158 on the top of button 142 engages with wire loop 156.At wire loop 156 in the situation that in engage position as shown in the figure, the button 142 of breech lock is prevented from inside promotion, thereby prevent that breech lock from by mistake being discharged.Therefore prevented that accident from overflowing.

Except preventing that button 142 from inwardly being pressed, wire loop 156 is extended to and is covered 144 and lid 144 is maintained in its closed position by the collar 154 from food pot.If breech lock 142 is not locked regularly, wire loop 156 provides lid is kept to the additional measure of closing.For example, if if food is absorbed in breech lock, stoped breech lock engage completely or user fails lid to be pressed in complete off position and to cause breech lock to keep the state that does not engage or only partly engage.Even button 142 is pressed latch with enough degree when wire loop 156 is in place, wire loop 156 will keep covering 144 and close.

Wire loop 156 can be made, can be various shape by metal, plastics or other material, can be installed in different positions and by the approach different from diagram, but such wire loop is still in protection scope of the present invention.Wire loop can be called as engagement member.

So, even if prevented from that food pot from being squeezed in lunch bag everywhere and collided or cover during pushing away or processing not initially being closed under complete lock-out state overflowing unexpectedly of food in food pot.

Food cans 140 also has body 160 and base portion 162.Hinge 164 is connected to the collar 154 by lid 144.Any parts of not describing in detail in this embodiment can be roughly the same with previously described embodiment.

In Figure 12, wire loop 156 has been moved into releasing position.In this position, wire loop 156 still remains in from the protrusion 150 of the collar 154 of food pot body 160, but do not rejoin, does not cover the button 142 on 144.Due to pivotable in the opening in the protrusion 150 of the collar 154 of the end of wire loop 156, thereby wire loop 156 can rotate between engage position and releasing position.Can see protrusion or the flank 158 at the top place of button 146.When user is buckled in wire loop 156 on protrusion 158 when wire loop 156 is moved on button 146, protrusion or flank 158 remain on wire loop 156 in engage position.By user, wire loop is departed from the buckle of button 146 wire loop 156 is moved to releasing position.

Wire loop is not only carried out (1) and is kept lid to close also the function that (2) prevent that button from by mistake being pressed, and carries out (3) and guarantee closing completely of lid, and (4) by button push the function to fully locked position.If user is pressed into lid 144 to close, but fail to bring lid 144 into close completely position, the effect wire loop 156 being fixed on button 146 will provide additional downward power to force lid to reach a fully closed position.As operculum 144 has been closed by user, and latched press-button 142 does not move to fully locked position yet, wire loop 156 is buckled in the effect of protrusion 158 tops on button 146 and wire loop 156 on the button being depressed, with downward and outside power, pull will pull button 146 towards extended position with joint efforts.The power being applied on button 146 and lid 144 by wire loop 156 is pressed into the in place position of closing completely by lid, and makes breech lock 142 can complete the motion that it arrives fully locked position.When user is buckled in protrusion 158 top on button 146 by wire loop 156, lid 144 is closed completely and sealing and button are locked completely.

In the position shown in Figure 12, lid 144 is still locked in the position of closing.Button 146 is in outward extending position, indicates the latch part 142 that operated by button 146 position in engaging.For latch 142 and open and cover 144, user inwardly presses on button 146.Thrust is along directed with respect to the radial direction of cylindric lid and tank body.

Figure 13 is illustrated in and after button 146 is pressed, makes to cover 144 food pots 140 that can be moved into open position.The opening 166 of locating by the top of tank 140 can touch the food in tank 140 or food can be put into open tank 140.By the pivotable of hinge 164, lid 144 moves to the position of opening completely, and Gai Buhui is disturbed the interpolation of food or taking-up.Hinge 164 remains lid 144 to be attached to tank 140 and to make Gai Buhui be misplaced position, and Gai Buhui becomes filthy from the teeth outwards because being placed.Can see the extension 168 of the insulation of the centre of covering 144, it extends in opening 166 food in food pot is incubated and is sealed when lid 144 is in the closed position.

The top of food pot 140 comprises the protrusion 150 that keeps wire loop 156.Wire loop 156 is switched to the body that leans on food pot in this view, makes it when adding or take out food, also can not bring any interference.The collar of food pot 140 or edge 154 also comprise when lid 144 is closed for receiving the opening 170 of the snap close protrusion of breech lock 140.
