Description

Drinking container

Technical field

The present invention relates to a kind of container that is used for beverage, especially for the container of soda, and relate to container in type described in the international patent application No.PCT/GB2005/000986, this container does not constitute the part of state-of-art.The present invention specifically but not exclusively relate to the container with wide mouth that is to say that diameter surpasses about 25mm or more containers, is preferably the container that surpasses about 38mm or 45mm.

Background technology

Drinking container has the only narrower mouth in 28mm or littler scope of diameter usually.Numerous methods that bottle top is sealed to the bottle bottleneck are for known to the public, but it should be understood that, the problem that produces for the sealing of the container of soda, increase along with the increase of bottle neck diameter forms exponentially, this be because the area of bottle cap or top downside along with square increase of radius.If container cover or its seal failure then can release of gas pressure, and lid even might produce in the air, thereby cause the loss of beverage, also can bring potential harm to the onlooker.Same sealing problem also may occur in the beverage of filling CO 2 gas not, this is because if container places under the high temperature action, for example, directly be exposed under the sunshine, then the gaseous tension in the container top space will increase, if container does not have enough sealings, then will cause gas leakage in air.This is not itself intrinsic problem, and when container cools off again, will produce pressure below atmospheric pressure in head room, thus the oxygen in the meeting aspirated air.The oxidation that this just may make the content of container causes beverage not drink.

With reference to Fig. 1 to Fig. 6 of accompanying drawing, will the container that illustrate among the PCT/GB2005/000986 be described below, wherein:

Fig. 1 is the vertical cross-section diagram of first embodiment with beverage bottle of the lid that is positioned at midway location and is used for bottle simultaneously;

Fig. 2 is the vertical cross-section diagram of described lid before being used for bottle;

Fig. 3 is the partial section on the top of described bottle, and expression is in the lid in application and the sealing station;

Fig. 4 is the lateral plan on the top of the bottle shown in Fig. 3;

Fig. 5 is the partial view of watching from the below of described lid, the draw ring that expression is broken; And

Fig. 6 is according to the container cover of second embodiment and the partial view of bottle.

As can be seen from Figure 1, bottle 2 is generally cylindrical, has at least a portion 4 that axis 3 and size increase, and the diameter of this part is greater than the diameter of lid 6, will illustrate afterwards this reason.In the case, bottle is made by plastic material is molded, and has the mouth of broad, and this mouth has greater than 28mm and the diameter that limited by the neck 8 of bottle.Neck 8 stops in the marginal portion that is limited by inside face 10 and outside face 12, and inside face 10 makes progress with respect to axis 3 and be outward-dipping, and outside face 12 makes progress with respect to axis 3 and slopes inwardly.Therefore, join in surface 10 and 12, and the overall diameter of bottle, particularly its marginal portion, and beginning increases downwards from the top.Yet the overall diameter of bottle reduces suddenly at downward annular shoulder 14 places that are basically perpendicular to axis 3 extensions of aiming at.Yet the interior diameter of described marginal portion begins to begin downwards to reduce from the top.

As shown in Figure 2, lid comprises the parts of one, preferably by elastomeric plastic material such as polypropylene is Unitarily molded forms.Lid comprises the closing panel of moulding, and this closing panel and web 16 form one, and when container cover was connected to bottle, described web extended on the edge of bottle.Sagging lateral margin 18 forms integral body with web 16, and described lateral margin 18 extends downwards around the outside of top of bottle.Annular locking flange 20 integrally is connected to the lower edge of lateral margin 18, or is connected to the inside face of described lateral margin in the position of the lower edge that is close to lateral margin 18.Flange 20 is elongated in axial, cross-sectional view, and is connected to lateral margin 18 by elasticity connection web 22, and elasticity connects web 22 thickness and reduces, thereby forms the line of weakness of annular or predetermined breakdown point.Rupture tab 24 is connected to described lid at a circumferential position, and this rupture tab 24 is extended downwards under the lower edge of lateral margin 18.By two line of weakness 26, i.e. the zone of thickness minimizing is connected to lateral margin 18 to this draw ring in its both sides.

The closing panel of described lid is recessed, thereby when this closing panel was connected to bottle, closing panel extended into the neck of bottle.Closing panel comprises usually wall part 30 downward and that extend internally, and wall part 30 is joined at the lower edge and the base part 32 of this wall part 30, and base part 32 is bent downwardly, and that is to say that base part 32 is reclinate convex shape.

Lid shown in Fig. 2 is a molded structure.In this structure, flange 20 downwards and extend internally, and the diameter of the lower edge of flange 20 is less than the diameter of the upper limb at the edge of bottle, the diameter of the upper limb of flange 20 is greater than the diameter of the upper limb at the edge of bottle simultaneously.

Lid is fastening and be sealed in bottle by simple snap-fit procedure.This exerts pressure and enforcement simply then by described lid is inserted the edge of bottle downwards.In the time will covering placement downwards, the lower edge of flange 20 and the edge contact of bottle.So just making flange center on web 22 inwardly rotates.As shown in Figure 1, along with lid continues to move downward, flange 20 moves down with surface 12 and contacts, and should increase by the diameter of surface on downward direction, causes described flange to continue rotation, therefore, makes the inside face of its close more lateral margin 18.Then, the upper surface of the following side contacts bottle edge of web 16.Yet described covering maintains pressure, and this will cause the slight deformation of web 16.Being designed and sized to of described lid and bottle:, be enough to allow the free end of flange 20 to move through shoulder 14 by slight further the moving downward of the caused bottle cap of the distortion of web 16.Then, as shown in Figure 3, flange 20 promptly inwardly rotates along relative direction by the elastic force of web 22, thereby locks behind described shoulder.Now, lid remains on the appropriate location on the bottle and can not move, and described lid is damaged or distortion.Tensile force keeps the downside of web 16 to cooperate with the upper surface at described edge, has the contact pressure that is enough to guarantee to form along the toroid of contact first air seal.Tensile force in lateral margin 18 also keeps the surface engagement of the free end and the shoulder 14 of flange 20, has the contact pressure that is enough to guarantee to form along the toroid of contact second air seal.In addition, connect the elastic force of web 22, the free-ended side surface of flange 20 is contacted with the side surface of bottle, and preferably, this contact pressure is enough to form the 3rd air seal.If desired, can also further improve the integraty of first air seal by annular ring or flange 17 are set, annular ring or flange 17 are only represented with the illusion line on the left side of Fig. 2, and annular ring or flange 17 will cooperate with the side surface at the edge of bottle, constitute other lid sealing.The position of this annular ring 17 is conspicuous to be designed and sized to: this annular ring 17 is by the lateral deformation with contacting of bottle edge, contact thereby forced with the side surface at described edge by the elastic force of annular ring 17, thereby forms further and seal.Be enough to make the high value of described lid away from the edge deformation of bottle if the pressure in the bottle is elevated to, first air seal is destroyed, the gas of supercharging will flow in the space that is limited by the outside face at described edge, lateral margin 18 and flange 20.This pressure will act on the flange 20, and flange 20 is pressed in the side surface at described edge more firmly, thereby increase the integraty of described the 3rd air seal.

Further sealing integrity if desired then can be provided with other air seal between the apparent surface 34 of the surface 10 at edge and wall part 30, as shown in the embodiment.Therefore, in this embodiment, these two surfaces form the complementary sealing surfaces that is sealed and matched each other.If the pressure in the bottle surpasses barometric pressure, no matter be because carbon-dioxide release in the soda, still because Yin Wendu increases the expansion of gas in the head room that causes bottle, the center of recessed base part 32 all will upwards be out of shape, and this will produce in the outward flange of base part 32 inherently, therefore, the lower edge of wall part 30 is slight outwards moves.This will cause the increase of the contact pressure between sealing surfaces 10 and 34, therefore improve the integraty of this other air seal.Therefore, not only have main and auxiliary air seal, and have other air seal according to drinking container of the present invention.Leak free integraty or seal ability that this is other increase along with the increase of the gaseous tension in the container.

When needs are opened bottle, as long as the user catches the lower edge of rupture tab 24 and is pulled outwardly.Line of weakness 26 ruptures immediately or elongates, and, be connected to the upper limb rotation of the draw ring 24 of web 16, thereby destroy the second and the 3rd air seal.This rotation is delivered to web 16, and the edge that therefore leaves bottle moves.Therefore destroy first air seal.Moving of web 16 also makes sealing surfaces 10 and 34 semistall, thereby also destroys described other air seal.Therefore make described container decompression.The outside motion of draw ring 24 begins to make thin connection web 22 to tear, and in case begun to tear, then only need simply by on draw ring 24, applying upwards and outside pressure, above-mentioned tearing proceeded, till described lid breaks away from the flange 20 that keeps the location around the bottle bottleneck fully.Can throw away lid then, and distribution and drink beverage in the bottle up.

As mentioned above, bottle has one or more projection 4, and when when axially watching, the profile extension of projection 4 surpasses lid.This just means that when a plurality of this kind bottles were packaging together side by side, these bottles only contacted with each other at projection, and the lid of adjacent bottles can not contact each other, thereby has eliminated the danger that lid may unexpectedly be removed, thus inside that can the emptying corresponding container.The shape of the pedestal of bottle can also with the shape complementarity of the upper surface of described lid, thereby make that bottle can be simply and be stacked on the top of each other securely.

In improved embodiment shown in Figure 6, the outside face of wall part 30 supports the projection 40 of annular, the surface engagement of the recess in this projection 40 and the described edge inside face.If being increased to, the gaseous tension in the bottle is enough to make the upwards degree of distortion of lid, thereby reach the scope that is enough to destroy first air seal, as shown in the figure, then the contact pressure on the surface of the top of described projection and described recess will increase, thereby further increase the integraty of air seal, and compensate the loss of first air seal.Projection can also be supported by the inside face at described edge, and in this case, described recess forms in wall part 30.If the gaseous tension in the container increases, then the contact pressure of the lower part of described projection will increase.

Though the container of explanation is very effective in existing the application, and has the failure-free air seal, can think, if container is heated to too high temperature, for example,, then still might lose efficacy if particularly inside is under the situation of soda owing to be exposed under the sunlight.In this case, the gaseous tension in container top space may be elevated to and makes closing panel upwards be out of shape the higher level of remarkable distance.

This distortion can cause the remarkable distortion of sagging lateral margin, makes sagging lateral margin away from the significant distance of the neck of container.Then, the elasticity of integral hinge can make the rotation of the sagging relatively lateral margin of ring seal flange and container, up to arriving in the position shown in half the partial view of the top portion of container shown in Figure 7.Any further motion that surpasses this point all will cause sealing flange owing to the gaseous tension that acts on the upper surface impact is arranged is rotated down, thereby cause the explosive decompression of container, also may make lid owing to gaseous tension is produced in the air.The content of container is no longer available, and probably forces ejection from container, says nothing of the danger that the onlooker is damaged.

Summary of the invention

Therefore, an object of the present invention is to provide a kind of drinking container, the container of particularly wide mouth type, described container has the lid of positiver sealing, even under relative high ambient temperature condition, described lid can hold the pressure that is generally produced by soda, if and produce extra high internal pressure, then described lid can be discharged into the inside of container the lower pressure that can hold easily, and can not cause the loss of bottle cap or container contents, and authorized pressure is not reduced to barometric pressure.

According to the present invention, drinking container comprises holder, this holder has central axis and passes through the lid sealing of elastomeric material, described holder comprises neck that limits opening and the lid that comprises closing panel, this closing panel and sagging lateral margin form one, described sagging lateral margin extends around the outside face of described neck, described lateral margin is supported with annular lip, down the downside of annular shoulder is sealed and matched on this annular lip and the described exterior, it is characterized in that, described annular lip is connected through the hinge and is connected with described lateral margin, described annular lip is elongated in axial, cross-sectional view, the free-ended end surfaces of described annular lip and the downside of described shoulder are sealed and matched, the inside face of described lateral margin is supported with the annular protrusion branch that a side surface with described annular lip is sealed and matched, the opposite side surface of described annular lip is sealed and matched with the outside face of described neck, therefore, annular chamber is by the inside face of described lateral margin, a described side surface of described annular lip, described projection and described hinge limit, and are provided with the gas passage that extends between described annular chamber and atmosphere.

Therefore, basic identical according to container of the present invention with the existing container of using, but comprise two supplementary features.First feature is, annular protrusion on the inside face of described sagging lateral margin divides or bump, described annular protrusion divides or the size of bump is designed to the location: this projection or bump are contacted with the outer surface of described sealing flange, thereby with its formation air seal.This will further improve the sealing integrity of container.In addition, by described projection applied pressure on the outside face of described sealing flange,, thereby can further improve the integraty of seal of vessel with the contact pressure that further increases between the outside face of the inside face of described sealing flange and described neck.Form the setting that the described annular protrusion of leak free divides with described ring seal flange, mean naturally that also annular chamber is limited by the outer surface of the inside face of described lateral margin, described ring seal flange, described projection and described hinge.This annular chamber usually with the inner sealing of container, but be communicated with atmosphere with a plurality of gas passages by one.

Gas passage can be arranged in any parts that limit described annular chamber, but preferably is arranged in the integral hinge with the form of a plurality of apertures.If the gaseous tension in the container is increased to the level that moves above the neck that makes described sagging lateral margin away from described container, described in this case lid is also inevitable have been moved and the contacting of disengaging and container neck, projection on the described lateral margin inside will break away from and the contacting of described sealing flange, and described annular chamber will with the internal communication in chamber.Yet this chamber also is communicated with atmosphere, and therefore the inside of described container is emptied to atmosphere.Therefore, the pressure of described container will begin to descend, but in case described pressure reaches certain lower level, the elasticity of described lid will cause various sealings to produce again, specifically, make described annular protrusion branch rebulid sealing with described sealing flange.Then, with stopping the emptying of described container and keeping pressure in the container,, the lid of container or the danger of content loss have been eliminated though be in level low and that can receive more.

Preferably, described integral hinge is resilient, and its elastic force makes its described opposite side surface rest on the outside face of described neck.Preferably, described closing panel is recessed, therefore extends into described neck, and comprises the base part that forms one with upwardly extending wall part, and described wall part is connected to described sagging lateral margin.Also preferably, described upwardly extending wall part is connected to sagging lateral margin by the web of annular, and the downside of described annular web extends in the surface of described neck and is sealed and matched with its maintenance.

Description of drawings

Further feature of the present invention and details are will be by the description of a concrete embodiment apparent, and this embodiment provides with reference to the embodiment of the Fig. 8 in the accompanying drawing and Fig. 9, wherein:

Fig. 8 is half the scheme drawing of Fig. 6 that is similar to the lid of container; And

Fig. 9 is when lid is applied to container, the similar scheme drawing of half of described lid.

The specific embodiment

According to container of the present invention and lid and basic identical, therefore will not repeat its explanation referring to figs. 1 through Fig. 6 illustrated container and lid.Yet, two main differences are arranged.

At first, integral hinge 22 has and is formed at one or more aperture 50.The second, ring uplift part or projection 52 are integrally formed on the inside face of sagging lateral margin 18.When the lid snap fit was to container, described lid rotated up nearly 180 °, forms in the structure shown in Figure 9.Projection 52 is forced to contact with the outside face of sealing flange 20 and seal with its formation.Be applied to the power of sealing flange by projection, the contact pressure that also makes the inside face of sealing flange act on the outside face of neck 8 increases, and therefore, has improved the sealing of container simultaneously in two different zones.In addition, annular chamber 54 is limited by projection 52, sealing flange 20, integral hinge 20 and sagging lateral margin 17 and forms.This chamber is communicated with atmosphere by hole 50, but the inner sealing of common and container.Yet if the pressure of internal tank is elevated to extra high level, lid will be owing to pressure distortion, and breaks at the top surface of the neck of container and the sealing at inside face place.Lateral margin 18 is outwards distortion also, and therefore the sealing between projection 52 and the sealing flange 20 also breaks.Therefore, the inside of container is communicated with atmosphere 50 by hole 50 and therefore can emptying.Then, pressure decay, the elastic force that reaches described lid up to this pressure are enough to resist the gaseous tension that reduces in the container and till recovering its shape.Then, rebulid various sealings, and the emptying of internal tank termination, the gaseous tension of container still is in the actv. level.Therefore, the content of container is retained in the container and is still available.
