Specific embodiment is described

Fig. 1 and Fig. 1 a are shown that a circular lid 1 seals the food 20 of vegetable dish 21, and this vegetable dish has disk side 24 and Nei Biao Face 23.Lid 1 includes that 30, elastic sealed body of a top board 10 (to seal inner surface 23, forms close between top board and plate Closed chamber 22), side wall 29 and handle 50 (to remove lid).Side wall 29 includes 28, evagination upper end 6 of main body, has bottom surface 15 Bottom, lower outer convex rib 14 and upper outer convex rib 27 to be accommodating elastic sealed body 10.Upper end 6 is accommodated by top board outer rim 4, and in addition Edge 4 is because heat or due to pressure are bent to form horizontal loops 5 side wall 29 to be locked onto on top board in bottom.

Elastic sealed body 10 has three sealing surfaces 16,17 and 18, is all formed in elastic sealed body bottom, and sealing surface 18 is water Flat, sealing surface 17 is about in 20 degree of angles.Sealing surface 16 encloses more outward-dipping to periphery from elastic packing body than sealing surface 17, With horizontal plane or face relative angle of trying to get to the heart of a matter in about 40 degree of angles.Bottom shape of the sealing surface 16 and 17 in 10 outer bulge loop 25 of seal Into, with allow they when inner surface 23 is more vertical the outward-dipping gradient more it is big a bit.Cannelure 26 is in ring 25 and seal 10 Side wall 11 between formed, sealing surface can be allowed more outward-dipping.Elastomer and elastomeric material (pillar A) are according to ASTM D- 2240 measuring and calculating, hardness range, are applied on seal 10 preferably 25 to 45 20 to 60.Bottom surface 15 and muscle 15 and 27, with Mode that is controllable and being constantly incremented by transmit the gravity or vacuum power (this will be discussed in figure 3) of lid to sealing surface 16,17, 18, to by 23 vacuum sealing of inner surface of plate.

It was found that traditional packing ring has flat or circular sealing surface, Hsieh is in United States Patent (USP) (US publication 2009/0101535) packing ring taught in has downward-sloping sealing surface.When vegetable dish is sealed, easily in even a few minutes a couple of days Vacuum loss is caused in clock, especially 22 in closed chamber in vacuum it is relatively low when occur.But it was found that with seal 10 Lid 10 is kept for the vacuum-packed time much longer, and vacuum sealing is up to several weeks even time of some months.

Handle 50 includes the 73, band of cylinder accommodated by opening 34 (being formed at the recessed median plane of top board 75) There are the attached screw 77 (to avoid handle 50 from removing from opening 34) of substrate 56, handle head 60 (to have one to be located in main body 73 The horizontal projection at end 59), and o-ring 78.Cylinder 73 and 34 frictional fit of opening.After lid is put plate, user Handle can be moved down by pressing handle head 60, it is possible to hold raised 59 times handles.Frictional fit makes handle (figure upward 1) and will not fall down, such handle head arbitrarily can be taken.Fig. 1 a show handle head 50 down position when, o-ring 78 sealing open Mouthfuls 34, and handle head major part is hidden in the closed chamber 22 below top board, 21 top is overlapped to accommodate other trying to get to the heart of a matter On plate 30 (as illustrated in figures 1 and ia).

When handle is not needed, its hiding function not only can help user that taking out for refrigerator and cabinet is saved in food storage Drawer space, and just open air is had a dinner party at last or hotel's sumptuous meal, and owner or waiter can disposably go up various meal, eat in quickening Speed, mitigation are served a dish load.This vacuum refreshing lid also has other benefits, such as storage food it is more fresh-keeping, for being incubated well-done meal Dish, and can prevent liquid food leakage from splashing.

It is to be appreciated that in the implementation this time and later of the present invention, except pan and plate, lid 1 Other vessel such as bowl, cup, bottle, cylinder, chest, chopping board and other sealing surfaces that can support can also be sealed.Except food, Other household articless can also be sealed, the industry and commerce article being such as placed in vessel.More it is to be appreciated that except this enforcement is with after Circular dishware described in the enforcement of face, lid apply also for square, ellipse, rectangle or other shapes of vessel.Also it is worth Must appreciate, top board is exactly briefly, on vessel bottom, there may be many shapes, such as circular, square, ring Shape, cardioid or ellipse.More it is to be appreciated that flexible handle 50 can be used for the glass of existing pan or other tablewares and cooker On glass or rustless steel lid, during food storage, handle can be hidden, and be easy to the overlap of vessel to deposit.

In Fig. 2 and 2a, in, the first modification of Fig. 1 lids only provides the top half of lid.Modification handle Including main body 73a (top head of a quilt 60a is encased), it is connected with the convex surface the depressed 85a of top board 30 with the screw 77 of belt substrate, one Valve groove 35 (having substrate 129 and valve opening 125), an elasticity or rubber valve body 127 (on substrate to cover hole), one Individual valved tube 74 (coordinating with valve groove, be installed on the side 32 of seal 127 to prevent seal from pulling out from valve groove), one Tubular opening 53 (to accommodate evacuator 84 shown in Fig. 2 b).Device 84 has the otch 87 of 83 lower end of tubular body 83 and tubular body, And the horizontal tube 76 being connected with vacuum pump (not shown).Valve seal body 27 has main body 73b and head 60b, and extends up to Opening 53 is taken with facilitating.53 size of tubular opening is accurate to the 83 height close fit of pipe with device 84, to prevent pipe 83 from existing Drop in evacuation process or mobile.The main body 73b size of head 60b and valve seal body 127 is accurate to. The side 32 of seal 127 some be not fixed to on valved tube 74, it is allowed to user pull-up head 60b is upwards with 10 to 100 Degree angle, preferably 30 to 75 degree angles, 129 He of substrate can just be cleaned when so cleaning in mobile valve seal unlocked part Part between seal 127.

OrVacuum cover evacuate vessel when, the handss of operator must be held and take out Empty device is not put, and in contrast to this, lid 1 can realize hand-free vacuum drawn.The tubular body 83 of device 84 is inserted by user Tubular opening 53 is fitted close therewith, and pipe 83 then is accommodated by main body 73b and head 60b automatically.Negative pressure is by valve seal body 127 are pulled upwardly, and open valve opening 125 and evacuate air (Fig. 2 a) in closed chamber 22.When vacuum is produced in chamber 22, it is allowed to another One plate base plate (not shown) can be overlayed on top board.When device 84 is removed, seal 127 drops to substrate 129 On, seal valve opening 125 to prevent vacuum leak occurs in closed chamber 22.Vacuum to be discharged, user can open valve opening with drop-down 60b 125。

Can belling face 85a may be designed as no external force act in the case of, rest on raised position, it is allowed to by pressing Handle head 60a generates a small amount of vacuum in closed chamber.When handle head is pressed down, convex surface 85a becomes a concave surface 85b, malleation Produce to push the release vacuum of elastic sealed body 127 upwards open in closed intracavity.When handle head unclamps, concave surface 85b attempts to reply To raised position to produce negative pressure, pull-up valve seal body, with close valve orifice 125, prevents concave surface 85b from returning to convex downwards successively Surface state 85a.

Although most problems of the existing lid that Fig. 2 lids were discussed in having processed background of invention, have Railway Project Exist.First, when valve opening 125 is sealed by seal 127, Jing foods often because of institute's band between valve seal body and substrate 129 Residue or dust leak air phenomenon.Second, i.e., using vacuum equipment 84, in closed chamber, also there was only 60% to 70% air one Rise and discharge, because this pump only possesses the ability for extracting 60% to 70% air out.3rd, top board 30 and side wall 29 need to thicken to be strengthened To support that No leakage vacuum, such lid weight increase cost and also increase.4th, lid can not seal the device less than itself Ware.

The second modification of Fig. 1 lids that Fig. 3 to 3c shows solves problem above.Improved lid includes first top Plate 30a (have opening 34 and bead 33), second top board (flexible seal 30b coordinates negative pressure is formed in closed chamber 22, and Negative pressure is converted into into downward force, is applied to elastic sealed body 10 to keep vacuum sealing), handle 50 is (with second top board 30b phase Even, can move to multiple positions at opening 34, as shown in Fig. 4 to 4d), film lock 31 (is used for locking elastic seal to side The peripheral surface of wall is 7).Be open 34 it is sufficiently large a handss can be allowed to put in, position handle 50 being moved to from top board on top board (Fig. 4 to 4d is discussed again after a while).The upper surface or elastica 30b of second plate, is not used by or in top position in handle When putting, connect with first plate 30a.This connects so that first and second plates seem an imposite, and the entirety in dish-washing machine Property works, to prevent foreign body from entering between 2 plates.This unexpected benefit that connects is exactly to use can product The vacuum sealing time of life-span and lid is substantially extended.

Based on the applicant's patent US7,594,586Lid, it is found that elastica is easy to from side wall or rigidity Frame lira goes out.Film lock 31 solves this problem in which includes that formed on top board 30a first lock (has first muscle 8 and first Bar groove 2 is accommodating elastica), second formed on side wall 29 lock (has Article 2 muscle 3 and the second bar groove 9 also for accommodating Elastica), the first bar groove 2 is engaged with the assembling of Article 3 muscle 3, and the second bar groove 9 is engaged with first assembling of muscle 8.First With Article 2 muscle apart from close, only separated by a vertical section of elastica 30b.It is believed that elastica 30b, side wall 29 The factor that elastica goes out from rigid border lira is easily made (to cover described in United States Patent (USP) 7,594,586 with dimensional variations of plate 30a etc. Son) it has been cancelled in film lock 31, so as to avoid the problem that film is drawn out.

Handle 50 includes that 35) handle body 73 (has base 45, cylindrical groove 51 and side wall；Interior main body 37 (has base 36 and side wall 43 With 51 close fit of groove, to encase the elastica between side wall 35 and 43 and between base 36 and 45)；Handle head 60 (has one Horizontal projection 59, first tube capacity receive opening 54 and upper groove 57 with reduce being open 54 height)；55 upper end of valve rod and handle head phase Even, lower end is connected with valve seal body 42, a pair of disc springs 61a and 61b, and each spring one end is connected with side wall 35, another End is then connected on valve rod；One valve opening 80 (is formed at inner valve body 37, to connect closed chamber 22 and air.Raised 41 on valve rod Can prevent valve seal body 42 from skidding off.One or more air flues 44 are formed in Ji36Chu, when handle 50 touches food by air Guide at valve opening 80.The opening 33 of base 45 and first top board is fitted close with fixed handle, while handle can also avoid opening 33 remove from bead 34.

The projection 46 of 35 inner surface of side wall groove corresponding to 43 outer surface of side wall coordinates, to avoid side wall 35 and 43 from separating.Film Print 49 is formed in the edge of elastica 30b, to be permanently secured on side wall 35 and 43.Film print 49 is elastic above interior main body 37 Generate on face, while generating aperture, the film around bottoming hole is allowed to bubble, and is advanced to 37 side wall 43 of interior main body and handle body The junction of 37 side walls 35.

Valve opening 80 has a side wall 79, its size just and with valve seal body frictional fit, with valve sidewall and valve Vacuum sealing is produced between door sealing body, allows valve seal body to completely close valve opening.Valve seal body 42 is coordinated with valve opening 80, can The upper and lower frictional movement in hole, and the cleanable valve sidewall 79 when mobile.Cylindrical appendage 40 is above valve sidewall Formed, to accommodate and guide the activity of valve seal body.Three uptake ventilators 47 (Fig. 3 and 3a) are on the side wall 38 of appendage 40 Formed, attached internal friction is moved into from valve opening when valve seal body to reduce.When valve seal body enters appendage from valve opening When 40, partial frictional coordinates loses generation, so as to form air flue 58 in 47 bottom of air flue successively, air can be allowed to pass through dish-type spring Opening 53, cannelure 48 and valve opening 80 on 61b is entered in chamber 22 (Fig. 4 b).

It is different from the lid valve of conventional technique or Fig. 6, this conduit acceptor handle openings 53 and 54, positioned at the upper of valve opening 80 Trip, and valve seal body 42 upward open wide, thus can directly contact cleaning solution or water, so as to have at valve 50 Any corner or spot as yet untouched by a clean-up campaign is difficult to the region cleaned.The tubular body size for accommodating opening 53 and 54 can just accommodate vacuum equipment The pipe 83 of 84 (Fig. 2 b), allows vacuum pump depletion closed chamber 22.The size energy storing apparatus 84 of opening 54 simultaneously interact, and depress handss Button 60, so as to remove downwards valve rod 55 and valve seal body 42, is lost with producing at least part of frictional fit, when the pipe of device 83 enter opening 53 and 54 when, formed air flue 81 (Fig. 4 d).Opening 53 is fitted close to lock at handle head with tubular body 83.

Opening 67 is formed on the roof 66 of cylindrical appendage 40, and size can just accommodate valve rod 55 and inside move. Opening 69 is formed between dish-type spring 61a and 61b, and size can just accommodate the motion inside of valve rod 55, to promote valve Bar and valve seal body 42 are connected with spring 61a and 61b.Recess 68 between spring 61a and 61b can make spring 61a and 61b Self-movement.Baffle plate 68 is formed on valve rod 55, and spring 61a and 61b are clamped between 60 bottom of handle head and top board, while See and allow handle head to pull up spring 61a and 61b (as shown in Figure 4 b), to open valve opening 80 and produce air flue 58.Seal sleeve 62 with Wall 35 upper end surrounding in side is connected, so that handle head (as shown in figure 4d) is sealed when handle head 60 is drop-down.

Spring 61a and 61b have enough length that valve rod can be allowed to move considerably long distance, and valve seal body is removed valve Hole 80, or the frictional fit allowed between valve seal body and valve sidewall 79 is lost produces air flue (Fig. 4), or some lost Frictional fit is producing air flue 58 (as shown in Figure 4 b).This spring has enough intensity overcome the frictional force of frictional fit, After valve seal body is caused friction forfeiture or some lost of frictional fit by movement, valve seal body is allowed to be returned to valve opening 80 It is interior, to produce air flue 81 or 58.The diameter of valve opening 80 can be between 2mm and 20mm, preferably between 5mm and 10mm.To keep away During exempting to store, aging caused gas leak phenomenon or accident are touched, 42 movable sealing distance of valve seal body, i.e., closed Between chamber and air during no any generation air flue, valve seal body in ultimate range from the valve opening 80 to vessel displacement, typically Be between 0.5mm to 15mm, it is preferably longer than 1mm and 7mm.

The handle 50 of Fig. 3 to 9 has many original performances compared with other valves.First, valve seal body 42 can make valve opening 80 sealings, even if valve seal body or valve rod remove some distance (as long as this distance than movable sealing apart from little), also not Can leak, have better seal than other valves for moving slightly the lower valve i.e. leakage of seal so as to handle 50 can be made.Second, Valve seal body 42 can remove dust on valve opening side wall 79, food debriss or other foreign bodies, i.e., during normal use, work as sealing When body is moved up and down, cleanable sealing surface.So as to handle or valve can be made self-cleaning, this is the key of lid reliability.3rd, It is the most important, valve seal body can move back and forth at first position, i.e. valve seal body sealing valve opening 80；May be used also On in second position movement, i.e. valve seal body at least partially in valve opening, first is formed between closed chamber and air At individual air flue；Valve opening can also be at least partly less than in the movement of the 3rd position, i.e. valve seal body, closed chamber and air it Between formed second air flue at.Lid handle head 60 allows user to move valve rod 55, so as to valve seal body 42 forms air flue down 58 allow air to discharge from closed chamber 22.Handle head 60 can also make user pull valve rod 55, so that seal 42 is upward with shape Into air flue 58, air is allowed to enter closed chamber, to promote lid to remove from vessel.

In Fig. 3 and other enforcements of the invention, it is to be appreciated that an appendage similar with cylindrical appendage 40 Can be formed in 80 bottom of valve opening.Also it is to be appreciated that the horizontal cross section of 67 and 69, i.e. valve rod 55 of opening and valve opening 80 can , there is the situation of any no calibration to prevent from being open between 53 and 54 in ovalize, square or other are non-circular.More have worth Appreciate, handle can with other variously-shaped cooperations than a circular one, such as ellipse, triangle, square, rectangle, Star or cardioid etc..Further it is to be appreciated that first plate 30a can be open 34 than handle body 73 with annular engagement Base 45 is big.Also more it is to be appreciated that handle head 60 and other secondary members can be minimized or be removed, and the work(of handle Can be like that valve works in sealing surface, have self-cleaning function in use.

Using lid 1, user can check that vessel are bigger or little than lid.If vessel are big, user holds handle 50 and exists Elastic sealed body 10 is placed on vessel interior surface 23.Using front, the handle with base 45 above plate 30a openings 34, first Or leave unused (Fig. 3) at unused position, air is evacuated so as to handle operation can be reached by.To produce vacuum storage food 20, User's pressable handle head 60, moves down opening 34 inner handle 50 to the second or following storage location, or part such as Below opening 34 shown in Fig. 4 and 4a.Handle base 45 pushes down on second plate or elastica 30b being connected with handle, promotes Air on food 20 is discharged by air flue 81, opening 80, groove 47, groove 48 and opening 53 and 54.Pressing handle head 60 promotes Spring 61a and 61b bend, and the valve seal body 42 of valve stem end is removed to anti-frictional fit direction from valve opening 80, to produce gas Road 81 (Fig. 4).

When handle head I unclamps, spring 61a and 61b push up handle head, valve rod and valve seal body, with shutoff valve Hole 80, handle head fall at storage location (Fig. 4 a), in chamber 22 form vacuum.Valve opening 80 is opened, user easily can be pulled upwardly Handle head 60, moving handle promote spring 61a and 61b to bend to the 3rd position, and valve rod 55 and valve seal body 42 are moved upwards It is dynamic to enter cylindrical appendage 40 to produce air flue 58 (Fig. 4 b).When handle is in the 3rd position, at first and second Between individual position, air then passes through air flue 58 into chamber 22, as a result promotes the 3rd position of handle to change, until handss Handle reaches first position.

If vessel are less (Fig. 4 c) than lid, user can be positioned over top board 30a and 30b on the side 24 of vessel 21.Elasticity The bottom surface of film 30b is smooth and the peripheral surface 7 that has one to communicate with vessel, by 24 vacuum sealing of side, lid is sealed and is less than The vessel of lid.Air-out is wanted to produce vacuum, user can be by depressing handle 60 similar to method shown in Fig. 4.Discharge true Sky removes lid, and user can be by similar to method pull-up handle shown in Fig. 4 b 60.In this handle 50 and other enforcements of the invention Handle, presses deeper or more shallow downwards, and air-out is more or less, so as to the vacuum for producing is then higher or lower.It is related to Thus the handle head position of the opening 34 or bead 34 of plate 30a may indicate that the vacuum below lid, for example, at handle head 60 When the position many higher than bead 33, vacuum is just low；When flushing with bead, vacuum is medium；When less than bead very When many, vacuum is just high.

The shape and size of existing lid are immutable, and unlike this, in Fig. 3, Fig. 5 and 7, lid has second top board 30b, coordinates food shapes application, so as to the vacuum pump (not shown) that more air more than food can be connected with device 84 is taken out It is empty.During use, the tubular body 83 of device is inserted in the tubulose body that can accommodate opening 53 and 54 by user, lower pushing hands button 60, bullet Spring 61a and 61b are bent successively, remove downwards valve rod 55 and valve seal body 42, to produce air flue 81.Seal sleeve 62 is by valve body 73 close fits being sealed between the tubular body of handle head, tubular body 83 and receiving opening 53 can avoid handle head from passing through spring 61a and 61b upward displacements.Because air is extracted out from closed chamber 22 by vacuum pump by air flue 81, valve opening 80, groove 47, chamber 48 All be stretched with tubular body 83 and elastica, and move down and cover food, and (Fig. 4 d) is closed with 20 matching form of food.

In Fig. 3 d, improved film lock 31 is standby for the lid 1 in Fig. 3.The only part of side wall 29 and first and second The part of individual plate 30a and 30b is shown.Side wall 29 against lid center slope inwardly, film lock 31 from side wall 29 inwardly toward Lid center, so can just overlap with multiple lids of size.Little opening 162 is beside side wall 29, away from opening 34 and handss Formed on first plate of handle 50, the fluid (such as water or air) allowed between first and second plates passes through.Improve film lock 31 to wrap Include first 165 (the having first muscle 171 and the first bar groove 163 to accommodate elastica 30b) of lock formed on top board 30a； Second 167 (the having Article 2 muscle 164 and the second bar groove 166 to accommodate elastica) of lock formed on side wall 29.Article 2 muscle 164 With 163 fit applications of the first bar groove, first muscle 171 coordinated with second groove 166.First bar groove 163 makes first plate bottom Wrapped up by elastica, to prevent film from removing from groove 163.As the film lock in Fig. 3, can prevent elastica from dividing from lock 31 From, first and second muscle only by a vertical section institute of elastica 30b every.

The first bar groove 163 on plate 30a is a continuous circular trough.But the side wall 29 around Article 2 muscle 164 On have multiple second bar grooves 166, have multiple first muscle 171 around upper first bar grooves of plate 30a 163, when Article 2 muscle 164 is entered During the first bar groove 163, fit applications enter multiple second grooves 166.Each first muscle 171 (has hook-shaped end including left muscle 171a End 170a), right muscle 171b (having hooked end 170b), the recess 172 (Fig. 3 e) between the muscle of left and right.Side channel 168 each second Groove 166 is formed below, to accommodate the hooked end of first muscle.The width of each the second groove 166 is than each 168 width of side channel It is little, the left muscle of its dimensional requirement and right muscle 171a and 171b local inclinations, it is therefore an objective to allow hooked end 170a and 170b to pass through.At least One in first muscle 171, the second groove 166 and side channel 168 has pointed members, strongly to be entered in first article of muscle 171 During two grooves 166, partial elastic film 30b can be separated.Separate elastica finds to prevent film from separating from film lock.It will be appreciated that , be so possible to form the second groove and muscle on the first lock 165, and can be formed on the second lock 167 first groove and Muscle.

Such as Fig. 5 to 5c, which provides Fig. 1 lids (has minipad 93 and sealing surface 16,17 with elastic sealed body 10 is improved Be connected with 18) the 3rd modification.Although Fig. 1 elastic sealed bodies can be longer than other lid Sealing periods, this is close Envelope not enough, because the inner surface 23 of most of kitchen utensils has rough phenomenon, and is not especially to justify.In addition, Even if vessel are standard circulars, can also work as lid it is not placed in the middle on vessel when the appearance of oval or irregular cycle is presented.It is little Pad 93 includes diaphragm seal 94 (in elastic sealed body bottom remote position), has first end 105 and elastic sealed body bottom Face is connected, the removable end 106 of also second relative resilient seal.Diaphragm seal 94 spends overturning angles in 1 to 89, preferably Horizontal by 2 to 80 degree angles, to reach long-time sealing effectiveness.Here diaphragm seal application is consistent with letter I italic shapes.I Find that diaphragm seal is outward-dipping and have been carried out the longer more long effect of Sealing period, thus second end 106 to the first Individual end 105 is from elastic sealed body periphery closer to (Fig. 5).Part diaphragm seal is relatively thin, can promote its soft whereabouts, work as lid When on vessel, lid weight causes part film to can contact elastic sealed body bottom surface, so as to promote the formation of vacuum.

Fig. 5 c are shown the modified version of minipad 93, and diaphragm seal 94 has a sealing at second end 106 herein Side 124.Sealing strip is than sealing thickness or at least sealing thickness a bit than the part adjacent with sealing strip.Side wall 29 in Fig. 5 d has One inclined end face 15, such side wall inner surfaces are just high than outer surface, it has been found that can so avoid food in use from side wall Enter between 29 and elastic sealed body, Fig. 5 d also show another modification of minipad 93, diaphragm seal 94 includes propping up herein Post 123 and base 122 are sealing vessel interior surface 23.Here 94 fit applications of diaphragm seal are in alphabetical L-type.

It is to be appreciated that inclining the pillar 123 in Fig. 5 c, diaphragm seal 94 coordinates in oblique V-type；Curved struts 123 and bottom Seat 122, diaphragm seal coordinate C-shaped；By the base 122 of bending, pillar 123 moves 50% to the left, and diaphragm seal coordinates in the T for reversing Type；By base 122, pillar 123 moves 50% to the left, and diaphragm seal coordinates in the Y types for reversing.Increase by one to second end 106 Pillar, then it is in letter U type that diaphragm seal coordinates.Because the combination of pillar 123 and base 122 and change have to inclined oblique diaphragm seal Affect, above-mentioned alphabetical L-type, oblique V-type, c-type, T-shaped, the reversing Y types for reversing and U-shaped diaphragm seal 94 typically are all regarded as inclining Oblique.

Also it is it is to be appreciated that diaphragm seal may be nearby formed in plastics or becket bottom or phase, close to form elasticity Feng Ti.Also it is to be appreciated that elastic sealed body 10 may only need to a small washer or diaphragm seal just can be sufficiently sealed interior Surface 23.More have it is to be appreciated that at least partly diaphragm seal is designed to contact with inner surface 23, and it is relatively thin, so as to Can be with the little recess on inner surface or male cooperation, its thickness is less than 1.5mm, preferably less than 0.75mm, optimal It is no more than 0.5mm.

Side wall 29 is made by stainless steel substrates, and top board 30a is made of then glass.The shape on the top 97 of side wall 29 of groove 88 Into to accommodate ring 90, clamping elastic sealing film peripheral surface 7.Glass plate 30a is positioned on ring 90, and sidewall upper 91 is along glass plate 30a is rolled, to be connected with the elastica print 92 formed at film periphery.It is similar to the handle 50 of Fig. 3, the handle head 60, handss of modification The elastica of there is clipped in the middle by shank body 73 and interior main body 37.Handle body 73 has a upper groove 57 to accommodate handle head 60.

Groove 52 is formed on the bead of groove 57, and pressing handle head promotes closed chamber 22 to be evacuated.Handle head has active side Wall 102, is accommodated by cannelure 48.First spring 100 is between the roof 66 and valve seal body 42 of cylindrical appendage 40 Compressed, to move down valve rod 55 and valve seal body 42；Second spring 101 is compressed between handle head and roof 66, To move up valve rod and valve seal body.During storage or when lid is not used, first, second spring is selective Ground is maintained at valve seal body at valve opening 80.First spring 100 is preferably made more solid, or has than second spring 101 There is bigger elastic constant value, to increase the sealing reliability of handle 50 and lid in vacuum storage.

Except glass plate 30a and elastica 30b, top board 30 further includes bottom dust cap 143, with interior 36 phase of main body base Even.Dust cap being contacted with elastic sealing film using front, or when closed chamber 22 is evacuated, (figure farther apart with elastica 5a).Which is bigger than handle body base 45, and has a plate 144 and multiple openings 146.

When user presses handle by mould to food or when lid is connected with vacuum pump, it has been found that dust cap can be prevented Elastica by food in sharp bone or shell puncture.It is then to prevent elastica that dust cap 143 has a unexpected benefit 30 are damaged in microwave oven, and especially when 1 lid food of lid has Fructus Lycopersici esculenti or oil, i.e., the applicant is in United States Patent (USP) Described in (patent No. US7,594,586)The related subject matter that lid occurs.Dust cap is preferably a little bit smaller, Preferably than 29 little 5mm to 40mm of side wall, so as to clean lid.

Handle head 60 is easily pressed during use, second spring 101 is compressed, so as to move down valve rod 55 and valve seal Body 42, to produce air flue 81, then pushes downwards elastica 30 open, and rush bypasses air through air flue 81 and (figure is discharged from closed chamber 22 5a).Elastica is moved down and promotes dust cap 143 to be connected with film and handle 50, so as to when air is discharged from closed chamber 22, Dust cap is moved down together with film.If user wants more air are discharged from food, (it is used for sealing upper groove 57 with tubular body 83 Handle head evacuator 84 (Fig. 5 b) 60) is pushed with bolt 107 to be inserted in the upper groove 57 of handle head 50.

Fig. 6 is shown the 4th modification of Fig. 1, compared with Fig. 5 lids, only one layer of top board 30 here, and Interior main body 37 plays handle body 73, is formed directly into top board.Cast groove 112 is formed at valve rod 55, top and 115 phase of groove Even, lower end 111 is connected with closed chamber 22.The tubular body for accommodating opening 54 is formed on valve disc 117, seal groove 115.Spherical sealed Body 120 is pushed valve disc 117 open to close opening 54 by spring 116.Side wall 29 is made up of rustless steel or plastics, has multiple yielding movables Pleat 119a and 119b, can coordinate its soft whereabouts when air is discharged from chamber 22 during pressing, or change its height, and not by There is resilience during pressing or be returned to the memory of elemental height, so that vacuum is formed in closed intracavity.

Similar with Fig. 5 and 5a, valve rod 55 and valve seal body are pushed down on by user's pressing handle head 60, to form air flue 81 (not shown).Pressure is passed through handle body 37 for handle head 60 and spring 101 and top board 30 is transported to side wall 29, is lived with the elasticity of compression Pleat 119a and 119b, air is extruded from chamber 22 by 81 (not shown) of air flue.When not pressing, handle head 60 is by spring 101 Above push away, close valve orifice 80；The elastic tuck of compression attempts to expand, so as to form vacuum in closed chamber 22.Vacuum to be discharged, moves Uncap son 1, similar with the method that Fig. 4 b show, user holds projection 59 or handle head 60, upper handle, promotes valve rod 55 and valve Door sealing body 42 is upwardly into cylindrical appendage 40 to produce 58 (not shown) of air flue, allows air to enter in chamber 22, compression Tuck is expanded and is returned to elemental height.

Air is evacuated with evacuator 84 shown in Fig. 2 b, tubular body 83 can be inserted into user the tubulose for accommodating opening 54 In body, under push the ball type seal 118, air is extracted out from closed chamber 22 by groove 112.

5th modification of Fig. 1 lids is presented in Fig. 7 to 7c.Improved lid includes first plate 30a, with first The side wall 29 being connected above individual plate, is had a bottom surface 15 and first plate and groove 2, is substantially located with second plate or elastica 30b On same horizontal plane.Elastica 30b includes a peripheral surface 7, and which has a glossy bottom surface to enable lid to seal vessel side 24, method is similar with shown in Fig. 4 c.Peripheral surface 7 has a big enable to cover the flat horizontal surface 18 of 29 bottom surface 15 of side wall, forms elasticity Seal 10, makes lid form vacuum sealing on the inner surface 23 of vessel 21.

It means that with Fig. 3 as the lid of Fig. 5, can seal more than lid and less than the vessel of lid.But It is that cost is lower than the lid of Fig. 3 and Fig. 5 more, because its elastic sealed body 10 is a peripheral surface of elastica 30b, Side wall 29 is a part of first plate 30a.Peripheral surface 7 beside side wall 29 from side wall 29 to handle 50 at it is downward-sloping, When lid is not used or is not positioned on vessel, horizontal by 50 degree of angles (Fig. 7).First plate 30a bottom surface is from side wall 29 It is also downward-sloping to median plane.This gradient is 5 to 75 degree angles, and preferably 10 to 60 spend angles.Such gradient we send out The tightness on vessel side 24 can be now lifted, makes elastica that inner surface 23 is sealed when gradient is larger, so as to help remove plate 30a Fluid and 30b between.

Peripheral surface 7 has a diagonal 17, including the predetermined altitude on 29 surface of side wall, communicates with vessel interior surface 23, To lift the sealing of vessel.7 outermost part of peripheral surface is connected with ring 82 with groove 2, and film print 92 is formed at film peripheral surface.Stream Body groove 19 is formed between diagonal 17 and side wall 29, including fluid layer such as air or liquid, further to lift elastica pair The sealing of vessel interior surface 23.Side wall 29 arrives the distance between section 17 and 18 of elastica 30b elastic sealed body 10 and bottom Face 15 connects, and including the surface of side wall 29, is variable cooperation, can make elastica section 17 and 18 preferably with vessel interior surface 23 Coordinate, further improve vacuum tightness.

Lid produce or assembling process in, ring 82 film is connected on side wall 29 or before, elastica 30b is stretched 1% to 50%, preferably it is stretched 5% to 30%.When lid is not used or is not placed on vessel, elastica 30b is in drawing Stretch and tense situation.This extended state can promote fluid such as air or water (if the first plate 30a and the second plate 30b it Between have if) discharge, when handle is moved to not from vacuum storage state (part handle is in opening 34 or plate 30a location below) Use state, at this moment handle is on opening 34 or major part is above.

In the applicant's United States Patent (USP) (U.S. Patent number：US 7,594, it is 586) middle to find a problem, through some months Widely use in a large number, fraction lid (such as about 4%, put to death in lid service life), it may occur that a small amount of vacuum leak. Once attempted film thickness is doubled to solve this problem, such as thickness increases to 0.1mm, but successfully probability from 0.05mm It is very limited.On average, the lid percentage ratio number for producing leakage have dropped about 30%, i.e., big when film thickness doubles About 3% is have decreased to from 4%.

It has been surprisingly found that when one layer of elastica is substituted by two-layer elastica in lid 1, producing the lid of leakage Percentage drop 250%, i.e., about have decreased to 1.5% from 4%, and this improvement is that we are original desired 10 times.Thus it is excellent Elastica 30b is selected to include multiple-layer overlapped elastica, its peripheral surface is connected with side wall 29 together.More surprisingly, when the two of lid 1 When tunic is sticked together by heat, after Jing extensively sends out use in a large number, 200 lids do not find there is vacuum leak.This just anticipates Taste, and adhesion process solves leakage problem, and is processed (as press polish, heating or pressure are combined, are laminated or extruded by adhesion Coating) 2 layers or multilayer elastic adhesion membrane can be preferentially used for lid 1.

Improvement handle 50 in Fig. 7 is simplified by handle cannelure 48 in mobile Fig. 3 and 5, including handle body 73 (having side 109 to prevent handle body from deviating from from below opening 34) interior main body 37 (has valve opening 80 and cylindrical appendage 40 to pass through handss Under tubular opening 54 on button 60, direct tubular opening 72 and 53 pairs of air are opened wide, valve seal body 42,100 He of spring 101 coordinate, even if when having negative pressure under handle head 60, as long as handle head 60 is not pressed or non-pull-up, can also allow valve seal body extremely It is rare to be partially left in valve opening 80.Cylindrical appendage 40 is covered by the roof 66 of handle body 73, has opening 67 to accommodate valve rod 55。

Handle body 73 can be moved up and down in the opening than 34 a little bit smaller points of opening, handle, prevent foreign body from entering the first He Space between second plate 30a and 30b.When handle is moved to below opening 34, static air layer 120 is first and the Formed between two plates 30a and 30b, adiabatic edge (Fig. 7 c) is provided for product 20 in closed chamber 20.It is to be appreciated that first Plate 30a can be connected with 29 top of side wall, on the second plate or elastica 30b.Also it is to be appreciated that vacuum sealing can be led to Cross o-ring or seal washer to be formed between opening 34 and handle body 73, when handle 60 moves on to from first unused position Behind two sealed storage positions, vacuum is maintained between the first and second plate 30a and 30b.

Using method：If vessel 20 are bigger than lid 1, user is placed on elastic sealed body 10 on inner surface 23, pressing Handle head 60 extracts air (Fig. 7 c) in chamber 22 out to produce air flue 81, and release handle head, valve seal body 42 are returned in valve opening, And allow vacuum to be formed in intracavity.Lid to be removed, user can using with similar approach pull-up handle head shown in Fig. 4 b.If vessel Less than lid, elastica 30b can be positioned over vessel bead 24 and be operated according to similar approach shown in Fig. 4 c by user.Pumping to be passed through Absolutely empty gas, user can will press handle head in 83 insertion opening 54,53 and 72 of tubular body of Fig. 2 b shown devices 84.Tubular body 84 There are 72 frictional fits with opening 53,54, make handle head be formed down o-ring 108, even if release handle head in evacuation process Opening 67 can be sealed.

The modified version lid of Fig. 7 shows in figure 7d.The groove 2 of modified version lid is towards on one side, allowing plastics or metal canula Elastica peripheral surface is clamped in 82 propulsions, and is connected on side wall 29, so that all elastic film inclined-plane 17 is communicated with inner surface and carried Rise sealing property.Dust excluding plate 143 has a disc plate 144 below the substrate 45 of handle head 50, is connected with interior main body 37, to bullet Property film plays a protective role, and mode is similar with shown in Fig. 5.Dust cap also has side 121, when lid is not used, can be in pressing table Basin or table top.

Substrate 45 is less than opening 34, and partial elastic film 30b exposures promote cleaning action outside.Elastica 30b is from side wall 29 To the centroclinal of lid, downwards followed by it was inclined upwardly before this.Groove 128 is formed below in substrate 45 and disc plate 144.Spring 101 tops are fixed on 60 bottom of handle head, and 101 bottom of spring is fixed at the plate 66 of handle body, so as to spring 101 not only Valve seal body 42 can be retracted in valve opening after handle head is pressed, can be when handle head is left behind, valve seal body being pushed away Enter valve opening.Fixed spring end can not only save spring expense, can also shorten handle, the stackable storage of vessel.

Fig. 8 and 8a provide the 6th modification of lid 1.This inboard wall includes lateral wall 28a and medial wall 28b, Position is at the predeterminable range of lateral wall.The inclined-plane 17 of elastic sealed body 10, the i.e. peripheral surface of elastica 30b, positioned at lateral wall Between 28a and medial wall 28b.Film lock 31 has a groove 9 and muscle 8 to clamp the exterior face of diaphragm seal.Stainless steel cover 149 covers side wall 29, there is top cover 30c to cover top board 30a, top cover upper shed 141 and elasticity or rubber ring 199 are fixed on cast opening 53, work as figure When 2b shown devices 84 are inserted, the friction of tubular body 83 can be increased, also bottom 148 is in lateral wall 28a bottoms turnup.

Passage 162 is formed at first plate 30a and allows air to enter, and is left fluid groove 19 and be sealed to inner surface 23 On the inclined-plane 17 of elastic sealed body 10.Using method：User inserts the inclined-plane 17 of elastic sealed body 10 in vessel, presses handle Valve rod and valve seal body 42 are released from valve opening 80 by 60, are produced air flue and are evacuated vessel, and then release handle makes valve close Envelope body close valve orifice, so as to keep vacuum (Fig. 8 a) in vessel.Lid to be removed, user can pull handle head, arrive by such as Fig. 3 Operate described in 7.

When the lid of Fig. 8 is tested, it has been found that even if the inclined-plane 17 of elastic sealed body 10 is removed in handle head 50, Vessel can be made to form long-time strong sealing.Without handle 50, the inclined-plane 17 of elastic sealed body 10 is only inserted vessel, is pressed by user Coping 30c allows inclined-plane 17 to deform, until inclined-plane 17 largely or entirely enters vessel.We have found that inclined-plane 17 and horizontal plane or When the relative angle of horizontal plate 30a is in gradient more than 15 degree of angles, preferably greater than 45 degree angles, optimal 60 degree are greater than During angle, lid coordinates best with vessel.We have found that lid has a resilience when unclamping, when passage 162 has angle of inclination During in about 60 degree or bigger, this resilience can be reduced or eliminated.

It is to be appreciated that the lid of Fig. 7 and 7d also can form long-time strong vacuum seal in no handle 50. Also it is to be appreciated that elastica 30b shown in Fig. 8 can be substituted by elastic washer or seal 10, coordinate in lateral wall 28a and Between the 28b of medial wall, including level top base 120, connect with top board 30a and side wall 29, base ring 18 and thin diaphragm seal 17 and top base Be connected (Fig. 8 b) with base ring.Diaphragm seal 17 is in be more than 15 degree of overturning angles with horizontal plane or 120 relative angle of level top base, preferably More than 45 degree of angles, it is desirable to more than 60 degree of angles.17 thickness of diaphragm seal is preferably less than 1.5mm, more preferably less than 0.7mm, to lift the performance of vacuum sealing vessel inner surface 23.

Fig. 9 to 9b provides the 7th modification of lid 1.This modification lid is similar with lid shown in Fig. 8, but It is to have modified handle 50, its handle head 60 is less.The handle of modification includes handle main body 37, and which has valve opening 80 and groove 150, handle 60 have cast body 151 to coordinate removable with groove 150, and outer lug 152 can prevent handle from removing from groove 150, cast opening 54, On convex along 155 and on along groove 52, valve rod 55 has upper cylinder 156 move in cast body 151, also and valve seal The bottom 41 that body 42 is connected.Upper cylinder 156 can prevent from removing from cast body 151 by convex 155, also by opening 158。
