The specific embodiment

Beverage can lid of the present invention and drinking container are described with reference to the accompanying drawings.

Fig. 1 has shown the part of drinking container of the present invention.Drinking container of the present invention comprises container cover 1 and vessel 2, and wherein container cover 1 is with known screw-threaded engagement or alternate manner and be connected on the vessel port 3 of vessel 2.

Container of the present invention can be any type of, for example, can be bottle, jar, box, bucket etc.Vessel 2 has the wall of container of thin-walled form, and it can be made by the material of various suitable forms as known in the art, for example the paper etc. of plastics, band membrane waterproofing.Container cover 1 can be made by the material of various suitable forms as known in the art, for example plastics, metal etc.

Container of the present invention is applicable to non-whipped beverage.As a representative embodiment of the present invention, container of the present invention is used to hold mineral water.In other words, container of the present invention is mineral water bottle or bucket, and wherein vessel and container cover all are made of plastics.

Introduce details of the present invention below in conjunction with Fig. 1-3.

The substantial cylindrical sidewall 12 that container cover 1 of the present invention has diapire 10 and extended downwards by the diapire outward flange.Among the application so-called about, be meant the above-below direction of under container normal upright state (vessel port is up).Sidewall 12 limits the longitudinal axis X that extends up and down of container cover.The inside face of sidewall 12 has screw thread 14, is used for screw thread 52 engagements on the outside face with the cylindrical mouthful wall 50 of vessel port 3, so that container cover 1 is connected on the vessel 2.

For the ease of handling container cover 1, the outside face of its sidewall 12 can be provided with anti-skid structure, for example the striped of longitudinal extension.

Alternatively, container cover 1 also comprises subring 20, and it is connected on the lower edge of sidewall 12 by thin discrete connecting portion 18.Described discrete connecting portion 18 is uniform along circumferencial direction, is formed with penetrating part 22 between them.

Vessel port 3 also is included in screw thread 52 belows and is formed on annular arrangement stopper section 54 and annular flange 56 on the outside face of mouthful wall 50.Final finished state when container of the present invention shown in Figure 1 is equipped with beverage, described subring 20 is embedded between described stopper section 54 and the flange 56.When along opening direction rotary container when lid, container cover can move away vessel port under threaded function, thus the described discrete connecting portion 18 of tear fracture.Like this, open circuited discrete connecting portion 18 expression container cover were opened.This just provides a kind of " show and surreptitiously open " function.

Certainly, this subring 20 only is optionally, and nonessential, therefore in other figure, itself and related discrete connecting portion 18 is not drawn into again.Be appreciated that in all embodiment of the present invention container cover can be provided with, also can not be provided with subring 20.

As unique distinction of the present invention, on diapire, be provided with the protrusion 30 of downward projection.At container the final finished state of beverage is housed, protrusion 30 inserts in the vessel port 3, and the upper limb of vessel port 3 on the lower surface of the diapire 10 of container cover 1, forms sealing with the certain pressure pushing and pressing thus between vessel port and container cover.Protrusion 30 has the upper end that is connected on the diapire 10 and is positioned at lower end below the described upper end.Footpath at sidewall 12 makes progress, and protrusion 30 is positioned at sidewall 12; Sidewall 12 vertically on, protrusion 30 is positioned at sidewall 12 at least in part, that is to say, protrusion 30 can be positioned at sidewall 12 fully, perhaps the lower end of protrusion 30 can extend longitudinally the lower edge that exceeds sidewall 12.

In order to help sealing, can on the lower surface of diapire 10, be provided with the auxiliary seal flange 16 that extends around the upper end of protrusion 30.Like this, at described final finished state, near the part the upper limb of vessel port 3 is clamped between the upper end of auxiliary seal flange 16 and protrusion 30, strengthens the sealing between vessel port and the container cover thus.

This auxiliary seal flange 16 only is optionally, and nonessential.Be appreciated that in all embodiment of the present invention container cover can be provided with, also can not be provided with auxiliary seal flange 16.

The effect of described protrusion 30 is described below.When filled drink in vessel, beverage is fills up to apart from vessel port upper limb one segment distance place, thus in vessel port, above beverage surface, stay not filling space, this space is occupied by air.The volume of described not filling space can come out by preliminary evaluation, promptly equals the volume of described protrusion.Like this, along with container cover 2 is screwed on the vessel port 3, described protrusion 30 can insert in the beverages, raising beverage surface, thereby with the air exhaustion in the vessel port.Like this, at described final finished state, do not retain air in the container.And when opening container cover 2, screwed and leave vessel port along with container cover, outside air can enter in the vessel port, thus the liquid level of the beverage in the vessel port can descend, and avoids thus or has reduced the possibility that beverage overflows.

The height of vessel port represents with H0 that in Fig. 3 the height of sidewall 12 represents with H1 that in Fig. 2 the height of protrusion is represented with H2 in Fig. 2.

According to calculating, can pre-determine the volume of vessel port and protrusion.

The volume of protrusion can equal 15% to 90% of volume that described vessel port limits, and is preferred 20% to 60%, and more preferably 30% to 50%.If the volume of protrusion is too little, it is insufficient that then container cover is opened back liquid level decline possibility, still has beverage and overflow when container moves.And if the volume of protrusion is too big, then can cause the waste of manufactured materials.

The height of protrusion more below.As previously mentioned, protrusion can be positioned at the scope of sidewall fully, also can exceed the lower edge of sidewall downwards.Preferably, the height H 2 of protrusion can equal 0.3 to 2 times of sidewall height H 1, preferably equals 0.5 to 1 times of sidewall height H 1, more preferably equals 0.6 to 0.8 times of sidewall height H 1.If the height of protrusion is too little, then can cause its volume too little, inadequate problem thereby said container cover unlatching back, generation front liquid level descends.And if the height of protrusion is too big, then can cause its aesthetic property to descend.

Described protrusion 30 can adopt any shape that is suitable for deaeration.The important point is to have the shape that pit etc. is easy to produce bubble on the surface of protrusion 30.In addition, the preferred direction of axis along the longitudinal of the cross-sectional plane of protrusion remains unchanged or reduces gradually downwards.

For the consideration of processing aspect, protrusion 30 can have regular shape, the shape of single swivel for example, the just shape that forms around a central axis rotation of one section straight line or curve.This central axis longitudinal axis best and container cover overlaps, even do not overlap, also unsuitable deviation is too many.

Shape as the swivel that constitutes protrusion 30 can adopt the frusto-conical shown in Fig. 2,4, the hemisphere shown in Fig. 5 (or part spheroid) shape, and cylindrical shape shown in Figure 6, cone shape shown in Figure 7, or the like.Also can adopt difform combination, cylindrical and hemispheric combination for example shown in Figure 8, or the like.

The shape that shows among Fig. 5,7,8 has an additional advantage, and promptly the lower end of protrusion diminishes gradually and converges at a bit, so the beverage that adheres on the protrusion can be concentrated towards this convergent point.

Certainly, protrusion 30 also can adopt the non-rotary body regular shape, for example shapes such as cuboid, square, prism, pyramid.

In addition, protrusion 30 can also adopt shape complete and/or the combined generation of part regular shape.For example, shape of the combination results of swivel and swivel, swivel and non-rotary body, non-rotary body and non-rotary body or the like.For instance, can be two or more cylinders of center arrangement or the like with described longitudinal axis.

In addition, protrusion 30 can also adopt irregularly shaped or complete and/or part regular shape and erose combination or the like.

Compare with regular shape, irregularly shapedly may in the manufacturing process of container cover, cause some troubles.However, it is irregularly shaped that the present invention does not get rid of use.

Protrusion 30 can be solid, also can be hollow.Situation when protrusion 30 is solid has been shown among Fig. 2, accordingly, the situation when protrusion 30 is hollow has been shown among Fig. 4.Similarly, other embodiment of hollow protrusion 30 has been shown among Fig. 5-8, those skilled in the art envision and they cooresponding solid protrusions 30 easily.

The advantage of solid protrusion 30 is that it can not influence the shape of the diapire 10 of container cover 1.As shown in Figure 2, it is smooth that the upper surface of diapire 10 is that outside face is still, identical with the conventional container lid profile.Certainly, the shortcoming of solid protrusion 30 is high material consumption.

The advantage of hollow protrusion 30 is can saving in material.Hollow protrusion 30 can produce one towards the extraneous cavity 32 that opens wide of diapire one side direction, thereby sees that from the outside the diapire 10 of device lid 1 is recessed into.The shape of described cavity 32 can be consistent with the outline of protrusion 30, that is to say, hollow protrusion 30 has roughly wall thickness uniformly.The shape of described cavity 32 also can be different with the outline of protrusion 30.For example, protrusion 30 is own cylindrical, and cavity 32 is semisphere.

Because the existence of cavity 32, the container cover of this profile might have influence on some customers' consumer psychology.In addition, may enter dust in the cavity 32.

For this reason, as supplementary features of the present invention,, can provide a cover plate 40, as shown in Figure 4 at hollow protrusion 30.Be appreciated that this cover plate 40 is equally applicable to the hollow protrusion 30 shown in other figure.Cover plate 40 can be smooth, and it can be bonded on the upper surface of diapire 10.In order to help the firm attachment of cover plate 40, can be provided with locating flange 42 at its lower surface, be used for buckling into cavity 32, to improve Joint strenght in friction tight mode.Locating flange 42 can be continuous, also can disperse.Logo that can printed product maker on the upper surface of cover plate 40, pattern or the like.

In addition, described protrusion 30 can form one with the other parts of container cover 1, as shown in Fig. 1 to 8.The advantage of this structure is that entire container lid 1 comprises protrusion 30, can make by commaterial, and for example by injection-moulding plastic, or the metallic plate punching moulding.Yet there is a potential shortcoming in this structure, and the alerting ability in promptly making is subjected to certain limitation.

For this reason, the present invention can also separate formation with the protrusion 30 and the other parts of container cover 1, is assembled into one again.The advantage of this structure is that protrusion 30 can be made with the material of the other parts that are different from container cover 1, thereby has improved the alerting ability of manufacturing process.For example, the other parts of container cover 1 are made of metal, and protrusion 30 is made of plastics.Perhaps, the other parts of container cover 1 are made by a kind of plastics, and protrusion 30 is made by another kind of plastics, metal or cork etc.In this situation, can the other parts of protrusion and container cover be combined by inlaying injection moulding.In addition, protrusion 30 also can be made by elastic body.

As example, shown respectively among Fig. 9,10 that hollow and solid protrusion 30 is combined in the other parts of container cover 1.Protrusion 30 can be provided with flange 34 in the top, and is connected on the diapire 10 of container cover 1 at these flange 34 places, for example by bonding or thermal welding.Perhaps, protrusion 30 can not be connected with diapire 10, and only prevents that by the screw thread in the container cover protrusion 30 from deviating from.

As supplementary features,, can in the diapire 10 of container cover 1, form the opening 36 that connects, as shown in figure 10 at the protrusion 30 that separately forms.This opening is equally applicable to situation shown in Figure 9.

As another supplementary features, shown in Figure 11,12,, can reinforced rib 60 be set for it in order to prevent the undercapacity of hollow protrusion 30.Described reinforced rib can for example metal, plastics etc. form by hard material.Reinforced rib is arranged in cavity 32, and extends along y direction.Birds-eye view from Figure 12, reinforced rib 60 is made of two blocks of plates that are right-angled crossing.Be appreciated that reinforced rib 60 can only be a mono-longitudinal extension plate, also can be meter plate of word intersection and constitute by three.That is to say, the concrete structure of reinforced rib 60 without limits, as long as can provide support for hollow protrusion 30.

The transverse edge of reinforced rib 60 can embed in the material of protrusion 30, to improve the Joint strenght between reinforced rib 60 and the protrusion 30.

In sum, the drinking container that the invention provides a kind of beverage can lid and use described beverage can lid, wherein be provided with the protrusion that inserts vessel port in the container cover, utilize protrusion, can avoid in filling having air in the container of beverage, simultaneously can when opening container cover, reduce beverage surface, to prevent or to reduce the possibility that beverage overflows.
