Detailed description of preferred embodiment

With particular reference to accompanying drawing, Fig. 1 has shown the beverage can 10 with interior thorax 12.Some beverages 14 in interior thorax 12, have been placed.Beverage can 10 has opening 16.But typical beverage cold drink or hot drink.Yet, the situation when structural design of the present invention has been considered the hot drink use especially, for example tea, coffee or hot chocolate.

Opening 16 can be with covering in addition capping of 18 first embodiment.Lid 18 flaky materials by plastics or other similar type, for example the paper synthetic constitutes.Lid 18 has enclosing cover 20 and inner cap 22.Enclosing cover 20 and inner cap 22 boths substantially are flat also for discoid.Yet, following situation also within the scope of the invention,

lid

20 and 22 discoids not just, for example square or for example hexagon or octagonal other polygon.Typically, the thickness of

lid

20 and 22 is about 1/8 inch usually.

Inner cap 22 has the week edge that forms ring edge 24.The upper edge of ring edge 24 gummed or otherwise for example heat-sealable way be fixed on the inner surface of enclosing cover 20.Ring-type drape edge 26 whole week edges that connect enclosing cover 20.Endless groove 28 is between drape edge 26 and ring-shaped edge 24.The edge, top that is positioned at the beverage can 10 of opening 16 is positioned among the endless groove 28 snugly.This will cover 18 firm being fixed on the beverage can 10.Yet, can by only the lid 18 be pulled away from change batch can 10 come with hand make cover 18 the disengaging beverage cans.

Inner cap 22 comprises inlet 30.30 normal lengths that enter the mouth are no more than 3/4 to 1 inch, about 1/4 inch of width.Inlet 30 is arranged in the off-centered position of inner cap 22.Inlet 30 has forward position 32 and back along 34.In case slanting beverage jar 10 is to the position that tilts, for example shown in Fig. 5, a spot of beverage 14 is flowed through inlet 30 in the space 36 of base closed, and this space is formed between enclosing cover 20 and the inner cap 22.

Dividing plate 38 is fixedly mounted in the forward position 32 on the upper surface of inner cap 22.Dividing plate 38 has the edge, top that contacts with the inner surface of enclosing cover 20.Dividing plate 38 comprises an arcuate wall, about 3/4 to 1 inch long of this wall, and importantly dividing plate 38 is the same long with inlet 30 at least.In fact, dividing plate 38 is made of " perforation output " material of the inner cap 12 that forms inlet 30.A gap area 40 is arranged between dividing plate 38 and ring-shaped edge 24.It should be noted that gap area 40 is no more than 1/4 to 1/2 inch wide usually.This means that dividing plate 38 is very near from ring-shaped edge 24, fully big to the space of ring-shaped edge 24 from the back like this along 34.Such reason is when beverage can 10 tilts, and beverage 14 is flowed through and entered the mouth 30, shown in arrow 42, flows to dividing plate 38, and walks around dividing plate 38, and is as shown in arrow 44, arrives among the gap area 40.Distribution openings 46 links to each other with gap area 40, and this hole is shown as triangle.Drinking person is positioned at mouth around the distribution openings 46, and upper lip is positioned at a little 48 zone, and but lower lip 50 has spacing near bottom 50 from the bottom.Select 48 and prevent beverage, if heat, with the upper lip of big arbitrarily degree contact drinking person.Can protect upper lip not scalded like this.Some distances though in fact must flow, from entering the mouth 30, pile warp dividing plate 38 arrived in the gap area 40 before distributing via distribution openings 46.The distance that flows should be enough to beverage is fully cooled off, thereby the arbitrary portion that prevents the mouth of drinking person is scalded.In addition, tap 52 is helped cooled beverage by making " steam " escape into the external world.

Hit or translate into because of carelessness if beverage can 10 is pushed, must guide beverage 14 via inlet 30, the fact via dispensing orifice 46 has reduced the accidental arbitrarily possibility unreasonable like a shrew of beverage 14 generations fully then.Even topple over to such an extent as to tap 52 is so little beverage cans 10, also can allow by these holes 52 flow to the outside beverage quantity be reduced to minimum degree.Such purpose is to prevent to pollute the clothes of the workplace of drinking person and drinking person and avoid contacting with the drinking person human body.

Though it is arc that dividing plate 38 as shown is, segmental baffle 38 helps to guide beverage 42 to flow along the direction of arrow 42, but what can be sure of is that dividing plate adopts other shape also can fall within the scope of the invention, for example adopt arrangement of line, even can adopt the convex opposite with spill shown in Figure 4.

With reference to accompanying drawing 6-9, shown second embodiment 54 of lid of the present invention especially.Second embodiment 54 comprises enclosing cover 56 and inner cap 58.Enclosing cover 56 and inner cap 58 boths are discoids.Yet, even what can be sure of is to cover 56 and 58 to adopt other shape beyond the discoids also can fall within the scope of the invention.In addition, the thickness of lid 56 and 58 is about 1/8 inch usually.

Enclosing cover 56 has the inner surface that limits interior thorax 60.Distribution openings 62 is formed within the enclosing cover 56.Distribution openings 62 is adjacent along 64 with the week of enclosing cover 56.Be positioned within the thorax 60 with enclosing cover 56 integrally formed convex surfaces 66, just in time setting is positioned at distribution openings 62 1 sides, and similar convex surfaces 68 is provided with the offside that is positioned at distribution openings 62.Convex surfaces 66 comprises and sees through groove 70, also is formed with the similar groove 72 that sees through in the convex surfaces 68.The purpose that sees through groove 70 and 72 is set will be further explained in detail in specification.Enclosing cover 56 also comprises outlet 74.Outlet 74 can be directly links to each other with the space 76 of the base closed of inner cap 58, perhaps can directly link to each other with the hole 78 that is formed on among the integrally formed post 80 of inner cap.It is in order to allow steam directly discharge from the interior thorax 82 of beverage can 84 that post 80 is set.The liquid 86 of heat, for example coffee or tea are contained among the interior thorax 82.

Enclosing cover 56 comprises the recessed portion 88 in the middle of being positioned at.Recessed portion 88 is to provide the intensity guarantee for the unitary construction of giving enclosing cover 56.

Inner cap 58 also comprises dividing plate, and this dividing plate form is a pair of separated upstanding wall 90 and 92.In upstanding wall 92 arranged outside holes 94.In upstanding wall 90 arranged outside holes 96.Gap area 98 is set between upstanding wall 90 and 92.By after for example bonding or sonic welded mode is fixed to enclosing cover 56 with inner cap, the upper surface of upstanding wall 90 is against convex surfaces 66, and the upper surface of upstanding wall 92 is against convex surfaces 68.

When beverage can just tilts, drink first mouthful during from the beverage in the beverage can, should there be beverage in the space 76 of base closed.In addition, if after drinking for the last time, spent some times again, so be contained in the base closed space 76 beverage 102 also can by ooze out hole 100 ooze get back in thorax 82, mix with hot drink 86 that to merge into hot drink institute warm.Yet when drinking first mouthful of beverage, in base closed space 76, there is not liquid under the normal condition, this is because beverage flow 94 and 96 is full of base closed space 76 through the hole, and then pile warp upstanding wall 90 and 92 is filled gap areas 98 and also needed some times (a few second).For filling these required several seconds, therefore allow beverage flow directly to enter gap area 98 when avoiding drinking first mouthful of beverage through seeing through groove 70 and 72.This initial direct beverage flow can provide instant a spot of beverage 104 to drink to the user.This flowing through can cause the reduction of the temperature of beverage through groove 70 and 72, thereby beverage is cooled off a little, in that initially to drink Shi Buhui too boiling hot.First mouthful drink after, can hold a certain amount of 102 beverage in the space of base closed 76.When the user drank another mouthful beverage, these a certain amount of 102 liquid are pile warp upstanding wall 90 and 92 only, and filled gap area 98 with a small amount of 104 liquid.Beverage inflow base closed space pile warp upstanding wall 90 and 92 then enters the 98 needed times of gap area, a certain amount of 104 beverages of directly drinking can cause a certain amount of 104 beverage temperature to be lower than a certain amount of 102 the beverage or the beverage temperature of beverage 86, to such an extent as to can not cause the scald of the mouth of drinking person.

The present invention can be embodied as other form, and does not deviate from its base attribute.Should with reference to attached claims rather than the preceding specification indicate scope of the present invention.
