Abstract

A lid with a raised drink-through spout ( 24 ) has a hinged flap valve ( 28 ) covering a drink opening ( 26 ') formed in the surface of the spout. The user opens the valve by pushing the top of a post ( 28 P) on the flap ( 28 F) down. A hinge ( 28 H) holding the flap urges the flap to return to its closed and horizontal orientation, but the top edge of the post will catch under a catch edge of the opening opposite the hinge. This holds the flap open. The user can then drink from the spout. To re-close the valve, the user applies inward force to the outer sidewall ( 16 ) below the catch edge. This causes the wall to deflect inwardly and the catch edge to distort outwardly, widening the hole. This releases the post, allowing it to move upwardly so that the flap can spring back to its horizontal and closed position.

Description

Lid with bistably valved drinking spout

The cross reference of background technology---related application

The patent application serial numbers that this patent comes from the submission of being abandoned now in 17 days September in 2004 is Nr.10/944, the application of 387 part continuation application.

Background technology---technical field:

Present invention relates in general to drinking container, relate in particular to the valve gap that is used for this container.

Background technology---prior art

Fast food restaurants, liquor store and other provand company can supply hot beverage in the disposable cup with lid or cover.Lid can keep the heat of the article in the cup and prevent that liquid from overflowing.Many lids have opening, and the user just can not remove lid from beverage under the cup like this.The beverage that some lids have protrusion connects the drink mouth, and these drink mouths allow the user to put lip on the spot the drink mouth to suck beverage more easily and safely.

For example, the patent 4,589,569 of authorizing Clements (1986) discloses a kind of dome lid that beverage protrusion and wide connects the drink mouth that has.Unlimited consumption aperture is to cut out from the top of drinking mouth.

The patent Des 417,845 that authorizes Sadlier people (1999) such as (present inventors) also discloses the dome lid that a kind of beverage with wide protrusion connects the drink mouth, and this drink mouth has unlimited consumption aperture at the top of drink mouth.

Above two kinds cover in market by business-like acceptance, all can sell millions of weekly.Although they are very successful, a shortcoming of consumption aperture is to open wide all the time.This obtains your drink then beverage to be brought to for those hope and has constituted problem the people that for example their office drinks of other place.When cup was carried, beverage can come out from the consumption aperture of opening wide in splash.In addition, before the user prepared beverage, heat can scatter and disappear from the consumption aperture of opening wide at an easy rate.Therefore, some beverage storekeepers will be placed on a strap on the hole, and beverage can not overflow and heat can not scatter and disappear before the user prepares to enjoy their beverage like this.This solution is consuming time, in disorder and unhygienic.

In order to address this is that, the inventor provides solution, for example authorizes the patent 4,899,902 of DeMars (1990) and the patent 6,644,490 of authorizing Clarke (2003).This patent disclosure have a protrusion beverage connect the lid of drink mouth and beverage and connect the drink mouth and have unlimited consumption aperture.Lid also comprises and is connected to the flexible arm portion that covers and has closure plug in the end of arm.When user or distributors wished closed beverage opening, they can insert the spigot end of arm in the consumption aperture of opening wide.When they wish to open once more when covering, they can remove stopper from consumption aperture.Although the beverage drink mouth lid to the protrusion of non-closure has been made improvement, these lids obtain to use widely, because the flexible arm that connects is very clumsy and can attempt disturbing them when drinking from cup the user.After consumption aperture was removed, it was wetting by beverage usually at stopper, and this trends towards making beverage to drop onto on user's the clothing from stopper.And, connecting drink mouth lid with the beverage of the protrusion of standard and compare, such lid can use more materials and Gai Gengnan to make.The open and close operation in hole is pretty troublesome and need use two hands.Lid is to make under the situation that Kongzui just opens wide and vanning; Therefore the waiter must manually insert stopper in the lid when beverage is offered the consumer.This can take more working time at the information desk place.Because these shortcomings, such lid does not obtain approval and the use on the wide range of commercial.

Authorize people's such as Smith (2004) patent 6,732,875 and the patent application of having announced 2002/0,011,494 of Lukacevic and shown that the beverage with protrusion connects the lid of other two-piece type Reclosable of drink mouth.These lids have two parts: outer cup and inner rotating disc, wherein the beverage of outer cup with protrusion connects drink mouth and beverage and connects the drink mouth and have unlimited consumption aperture, and inner rotating disc has the consumption aperture enclosed member.Movable disk also has the column that extends upward by the groove in the outer cup.By column is moved by side to opposite side from one of groove, dish can be rotated with the open and close consumption aperture.Although on function above-mentioned lid is improved, the formation of two-part construction is very expensive.Need additional plastic material to form outer cup and internal activity dish, and need additional manufacturing procedure that two parts are tightened together.Therefore these lids have very big shortcoming than other of the prior art lid discussed above on cost.

Herbst is in patent 4,925, in 051 (1990), Albert is in patent 4,186, shown in 842 (1980) wherein to form the normally closed lid that enters otch by downward power.

Montemerano is in patent 4,333, in 583 (1982) and people such as Ryan in the patent application 2004/0,094,549 of announcing, shown lid with drink mouth, and the drink mouth has the cover that can open to drink.

Coy is in patent 4,782, shown the lid with drink mouth in 975 (1988), and had valve in the drink mouth.Valve can be opened by the pressure of lip.

Kick is in patent 5,894, in 950 (1999) and Van Melle in patent 6,089, shown lid in 397 (2000), and flap has frangible annex with flap, it just can break away from from the remainder of lid it is opened allowing and drinks like this.

People such as Bruce are in patent 6,419, have shown a kind of lid in 105 (2002), and this lid has part drink mouth or funnel (on-beverage connects type) and is lower than the cylindrical part of drink mouth, this cylindrical part can be out of shape come with the bistable mode open or closure it.The beverage drink mouth that the operation of this lid can not allow beverage to connect type is subjected to consumer and food supply operator's welcome.

People such as Hundley are in patent 6,612, in 456 (2003) and people such as the Schmidtner patent application 2003/0 of announcing, 218, shown lid in 017, and hinged valve comprises the protrusion fin of hollow, protrude fin and can be depressed to open the hole with consumption aperture and hinged valve.

All these lids have one or more shortcomings, comprise complexity, unreliable, expensive, be difficult to use, clumsy, expensive or the like.

Therefore, all current lids with beverage perforation drink mouth of protrusion have different shortcomings: beverage can come out and the meeting loses heat in splash, belt uses clumsy and can not reseal, sealing-plug can disturb drinking of user, the beverage of inside can drip when opening, and uses relative wide variety of materials, needs to use a large amount of time and work, the formation of two parts formula lid is expensive and need wide variety of materials, and other lid complicated, unreliable, expensive, be difficult to use and clumsiness.

---advantage

Therefore several advantages of the present invention have provided the bowl cover of drinking with drinking spout mouth, it: (1) has improved the lid of prior art, (2) do not need to use the closed consumption aperture of belt, (3) resealable, (4) can not disturb or hinder drinking of user, (5) do not have any part of dripping when opening, and (6) use the material of relatively small amount, (7) need use little time, material and work, (8) use simple, reliable, economical and easy.

Other advantage has provided the lid with closure member, this closure member can: (9) cover the beverage opening fully and are opened by the user until it, (10) in case open and just remain on stable open position until by user's closure, (11) can be closed once more by the user, (12) make by from one piece, (13) can use the operation open and close of a hand, (14) health, (15) being integrated into the beverage with protrusion connects in the lid of the standard style of drinking the mouth layout, (16) user can more easily make and be used for drinking and (17) more anti-splash when consumption aperture is opened by lid.

By considering that accompanying drawing and the more advantages of explanation subsequently will become more apparent.

Summary of the invention

According to the present invention, new having the beverage perforation drink mouth of protrusion with improved lid and cover beverage perforation drink mouth has the beverage opening of being with valve.Lid is formed by from one piece.Cover on its base and have installation portion, this installation portion comprises the elastic ring holding tank, and this holding tank is designed to the globule is clamped on the top of cup.Annular outboard wall or tower, the lateral wall of preferred frusto-conical from installation portion upwards and extend internally and have annular top or flange, annular top or flange have circular substantially circumference at the top of lateral wall.Tower has the central fovea slot part of the central plate that forms lid.Flange is higher and wideer in a side, therefore forms the drinking spout that protrudes.

Beverage in the drinking spout connects valve and comprises the rectangle flap at the top surface or the chi chung of flange.Flap has integrally formed projection that makes progress or column.Flap by along the line of cut of leading edge, on each lateral edges crooked line of cut and limit along antemarginal hinge.Hinge lines is preferably in " activity " or the integral hinge of the inside edge of roof.

The user applies downward power by the top to column makes flap be bent downwardly along hinge lines, and flap just extends to lower angle with one with the surface of ridge or flange like this, thereby opens valve.The hinge of flap has spring-operated, this spring-operated promote flap return its closed and level towards.Yet when the top of column is pushed through the cutting leading edge of roof or clamping (catch) edge, it will be connected to this below, edge and flap will be locked in the open position.This will prevent that flap from returning and---and therefore with valve---remains in the open position to generate the beverage pass through openings with flap.Therefore the user can come normally to drink from lid around the beverage drink mouth that protrudes by the lip with them.

If closed valve once more, the user applies inside power on the point that is lower than cutting leading edge place on the lateral wall.When this power was applied on this point of release, it can cause antetheca outwards to be out of shape to the cutting leading edge of intrinsic deflection and consumption aperture, thereby has widened the hole.The top that this can discharge column allows it to move up, so just can rebound its level and closing position of flap.

Detailed description-Fig. 1-lid of the prior art

Fig. 1 has shown that beverage of the prior art connects the perspective view of dome bowl cover, and this bowl cover is similar to the lid shown in people's such as the Sadlier recited above design patent.This lid has the base flange 10 of annular, and this base flange 10 has from the outward extending little flange 1OF in its bottom.The downside of flange 10 forms towards the annular cup-flange-clamping of below and seal groove 12 (best referring to Fig. 2 C).Tower or dome part 14 extend upward from the inside of groove 12; Tower 14 has frusto-conical and has vertically wall 16 of annular.Tower 14 have the annular top horizontal surface that extends from the top of wall 16 or ridge 18 and by ridge 18 around and be lower than the groove 20 of ridge 18.Wall 16, ridge 18 and groove 20 form annular upper flange 22 thus.In other words, flange 22 is the top of tower 14 and encirclement and has defined groove 20.The first half of flange 22 is inclined upwardly and flattens then forwardly to form that protrude or higher and wideer drinking part or drink mouth 24.Drink mouth 24 has the beverage opening 26 that cuts away from ridge 18.Cut out little air vent 26A relatively with opening 26 in ridge 18.

As described, covering in market by business-like acceptance and all can sell millions of weekly among Fig. 1.Although it is very successful, a shortcoming of opening 26 is patents or unlimited.This obtains your drink then beverage to be brought to for those hope and has constituted problem the people that for example their office drinks of other place.When cup was carried, the beverage below cup in the (not shown) can spill from lid.In addition, before the user prepared to drink its beverage, heat can scatter and disappear from the hole of opening wide at an easy rate.Therefore, some beverage storekeepers will be placed on a strap on the hole for the client, and beverage can not overflow and heat can not scatter and disappear before the user prepares to enjoy their beverage like this.This solution is consuming time, in disorder and unhygienic.

As described equally, valve gap is known can be prevented splash and reduce heat loss, but these valve gaps have a lot of shortcomings, comprise disturbing the drinking of user, the beverage that can drip in inside when valve is opened, needs to use relative wide variety of materials, too much time and work, manufacturing expense height, need lot of materials manufacturing, the complexity of using, unreliability, difficulty and clumsiness and can not remain on before by user's closure to open in the configuration.

Fig. 2 A-has the lid-general description of valve

Fig. 2 A has shown the lid that has valve according to of the present invention.This lid is similar to the lid among Fig. 1, and replaces patent or unlimited consumption aperture 26 and have outside the valve 28, and it has all identical reference numbers.Valve 28 comprises the hinged flap 28F of rectangle substantially, and flap 28F has monoblock type column or protruding 28P.Flap 28F has crooked side and straight leading edge and is hinged to back edge on the top surface 18 by movable or natural hinge 28H.That is, hinge 28H is positioned on the inner hinge edge in hole (be designated as now 26 ').Hinge closes on groove formation along the inward flange or the back edge of annular top.In order to help hinge function, one section hinged edge can be made for straight.Perhaps hinge can be designed to the part of top surface, and design is for forming groove, and wherein flap 28F expectation will be crooked in this groove.As flap 28F during as shown in the figure with ridge or top surface 18 coplanes, the valve closure provides and drinks opening but can as described belowly open it at an easy rate by depressing flap 28F.

The lid of Fig. 2 A preferably forms by hot forming, but also can be by any formation in the multiple manufacture method, and these manufacture methods for example are injection moulding and/or vacuum forming.Preferably, it by plastics for example polystyrene (preferably), polypropylene, polyethylene or arbitrarily other suitable plastic material make.Column 28P preferably flap 28F integral part and form by hot forming, the material of column just can be stretched from the flap main body like this.In one embodiment, lid to be dimensioned to flange with 90 mm dias and flange be that the dixie cup (not shown) of 3 mm wides cooperates.It is that 4 millimeters and diameter are 3 millimeters that flap 28F is of a size of 14 millimeters height of taking advantage of 4 millimeters and column 28P.Its surplus size is designed pro rata.

As will showing, valve 28 has improved lid of the prior art, because except other, it can reseal, can not disturb or hinder drinking, prevent the beverage splash in the cup and keeping beverage hotter of user at an easy rate.

Fig. 2 B and 2C-top and side sectional view

Fig. 2 B and 2C have shown the top and the side sectional view of lid, and Fig. 2 C cuts open along the hatching 2C-2C among Fig. 2 B.As shown in Fig. 2 B, groove 20 is positioned at the center of lid and is centered on its ridge 18 by flange 22.Drink mouth 24 comprises that valve 28 and valve 28 have flap 28F and column 28P thereof.Should be noted that flap 28F has the long rectangular shape of the crooked lateral edges of band, this be similar to hole 26 among Fig. 1 or the hole 26 among Fig. 2 B '.

Fig. 2 C has shown base flange 10 and recess 12 with profile; Recess 12 is forced to place on the top flange of dixie cup (not shown), and groove will closely remain to lid on the cup like this.Wall 16 extends upward in flange 10 inside to form tower or dome part 14.Upper flange 22 and upper flange 22 formation and encirclement groove 20 are formed on the top that the ridge 18 of tower 14 has projection or drink mouth 24 and tower.Should be noted that, comprise in the upper flange 22 that the part of drinking mouth 24 is wider than the remainder of upper flange 22 slightly.

Fig. 3 A, 3B and 3C-have perspective view, top enlarged drawing and the part side sectional view of the lid of opening valve

Fig. 3 A has shown the perspective view of lid, lid has that the valve 28 of downward promotion and opening are drunk mouthful with formation or hole 26 '.Hole 26 ' be similar to the hole 26 among Fig. 1, difference is that flap 28F extends from the inward flange in hole downwards.Column 28P also is pushed down to such an extent that be lower than the neighbouring part of ridge 18.

Fig. 3 B has shown the plane of the amplification of the lid among Fig. 3 A.Should be noted that flap 28F is bent downwardly at hinges 28H place, generate patent or unlimited hole 26 '.That is, a side of flap hinges 28H place be connected to hole 26 ' dorsal part or the hinge side on.The top of column 28P be locked in hole 26 ' relative leading edge or the below at clamping edge.If the top of column is not locked in the below at the clamping edge in hole, hinge 28H will tend to make flap to turn back to its closed horizontal level.Yet because column is locked in the below at clamping edge, so flap is exactly bistable, promptly it has two settling positions: open position and closing position.Column be dimensioned to that its just is acute angle with top surface 18 of drink mouth downwards and extends like this when flap rotation, and when column is relative with flap 28F with top surface 18, the top of column will with hole 26 ' the clamping EDGE CONTACT, flap will remain in the open position like this.

Fig. 3 C has shown in the side of the part of the lid of cutting open along the line 3C-3C among Fig. 3 B that comprises valve 28 and has analysed and observe detailed view.Should be noted that equally flap 28F is bent downwardly at hinges 28H place, generation hole 26 '.The top that is to be further noted that column 28P be locked in hole 26 ' leading edge or the below at clamping edge.

Fig. 4-have part side sectional view of the lid of closed valve

Fig. 4 shows that valve returns the side sectional view of the lid among Fig. 3 A of its closing position.When the user uses finger 30 when pushing on wall 16 as shown, with the part of finger 30 walls that contact will distortion as illustrated or be pushed.This can cause the top of the wall above finger and comprise hole 26 ' the adjacent part outside distortion as illustrated of ridge 18 at clamping edge.This will allow the clamping edge that slides past as illustrated, top of column 28P.Flap 28F is shown as in rotary course and returns its level or closing position.Hinges 28H will cause flap rotation or rebound until it closed basically and with ridge 18 coplanes, shown in Fig. 2 A to 2C.

Operation

The closure of valve: the valve 28 that in closure state (Fig. 2 A), is provided with them that covers of the present invention.The flap 28F of valve and its base coplane, and base is the part of upper flange 22.Flap will have this position usually, or be bent upwards or rotate to the position that just is positioned at above its base (not shown) after the cutting slightly in perforating die.If it rotates to the position that just is positioned on the base after punching press, it just can be pushed down in mould, like this it just with its base coplane, as shown in Fig. 2 A; This can make the user promote flap downwards more easily to open valve.(it also can be pushed lowlyer, as hereinafter in conjunction with as described in Fig. 5.)

The cup (not shown) in beverage shop, family or distributors etc. locate to be filled beverage, and lid is snapped into downwards on the flange of cup.User or drinking person are taken away cup with a lid, for example take job site, vehicle, working site etc. to.Because valve is closed, so lid is fully closed basically, although like this by rough use, inner beverage can not come out in splash yet.But also can reduce the scattering and disappearing of heat (or the entering of heat, the words that are cooled as fruit beverage).

Opening of valve:, flap 28F is rotated down on hinge 28H gets final product if want beverage, user only to need to use a finger or thumb (not shown) to promote column 28P downwards.When flap rotates enough far, the top of column 28P will be clipped to hole 26 ' leading edge or clamping edge, shown in Fig. 3 A to 3C.When hinge 28H promotes flap 28F when closed again, flap can not be done like this and it will remain on open position (Fig. 3), this be because column 28P be locked in ridge 18 and hole 26 ' below, clamping edge.Therefore flap stably remains in the open position.User's (not shown) now their lip is placed on around the drink mouth 24 and the hole 26 by opening wide ' from cup, drink.Beverage will freely flow through hole 26 ', through flap 28F and column 28P thereof, enter in user's the mouth.

Because additional benefits, even when consumption aperture is opened, valve also provides spray resistance.When valve was opened, shown in Fig. 3 B, hinged flap 28F and column 28P served as the inner splash guard of lid to stop that some liquid are by opening 26 ' splash out.

The closure of valve: if the user wishes to interrupt their drinking before all beverages in having drunk cup, they can following closed valve 28: as shown in Figure 4, the user uses finger 30 inwardly promoting on wall 16 below the ridge 18.This cause wall 16 this part as shown in the figure to intrinsic deflection, this can cause again the top of wall 16 and hole 26 ' leading edge and the clamping edge outwards be deformed into the top that is enough to allow column 28P make progress slide through holes 26 ' leading edge, like this flap 28F will be closed and reseal opening 26 '.Therefore cup just can be carried and use now and its beverage can splash come out and can reduce heat by hole 26 ' transmission.The user removes their finger 30 from wall 16, allow wall to return its distressed structure and allow its normal configuration of hole 26 ' return not normally.

The applicant believes that now following explanation is correct, but does not wish to be subjected to its constraint.The applicant believes that the top of wall 16 and the leading edge and the clamping edge in hole 26 ' can outwards be out of shape the user when the lower position of wall 16 inwardly promotes, this is that the fulcrum of this lever is between the summit of point that wherein applies power and wall because wall 16 serves as lever.Fulcrum is to be formed by the hardness of lid owing to the round-shaped of lid.

Except said method, also has the closed hinged flap 28F of alternate manner.Beverage drink mouth 24 can be extruded before finger and thumb or roll.This will make this part distortion of lid and therefore column be discharged from the clamping edge and allow the flap closure.Perhaps, the user can remove lid and use finger upwards to promote the downside of flap with closed flap from cup.The user just can reconnect to lid on the cup then.

Reopening of valve: when the user wished to drink once more, they can be column 28P to pressing down to open flap once more.Column 28P will be locked in the below at the clamping edge in hole 26 once more, because the hole has turned back to its initial configuration.

The promotion of the flap of Fig. 5-valve below base

As described, lid can be formed with the flap 28F of valve, flap 28F shown in Fig. 2 A with its base coplane or (not shown) above its base just.Yet the applicant has been found that the user can find to supply with the flap that the top surface that is bent to the position that just is lower than base or drink mouth is downwards arranged as operculum, as shown in the local figure of Fig. 5, with regard to easier flap is pushed to open position (Fig. 3 C) downwards.This position can generate covering in the perforating die (not shown) when forming, its mode is for providing spring loaded stripper pin (show, but be well-known for those skilled in the art) after flap is stamped flap is pushed to below its base slightly downwards to former.Flap will make progress when making it promote lowlyer downwards and discharging from being screwed into this position, because flap hinge 28H will make it rotate up EDGE CONTACT until its edge and its base, this will make it to stop.

When lid is provided the flap that is in this position (Fig. 5), inner liquid will can not come out because valve is still closed in splash.Yet the user can push it down moving to open position (Fig. 3 C), because it has been lower than its base easily.The opening valve can be to cut out and to be back to the closure state of Fig. 5 with identical mode discussed above.

Fig. 6 and 7-flap are hinged to the outside in hole

Replace being hinged to inward flange or hole 26 (being best shown among Fig. 4) of beverage opening, flap can be hinged to the outward flange of opening 26, as shown in Fig. 6 and 7.The hinged flap 28 in Fig. 6 China and foreign countries ' be shown as downward extension and opening, but turn back to its closing position, as shown in Figure 4.Yet, flap 28 ' locate to be hinged to the outward flange of opening at hinge 28H ', like this free edge of flap or clamping edge 28F ' will be more near the inward flange in hole.That is, the hinge edge of the opening clamping edge that closes on the outward flange of lid and opening closes on the center of lid.Below but the hinged flap 28 in Fig. 7 China and foreign countries ' close just places its base, be similar to the embodiment of Fig. 5.
