Description
Technical field
The present invention relates to a kind of container, the inner space that this container is used to hold certain amount of fluid and leaves certain filled gas simultaneously.
Background technology
This container is equipped with plug cover usually.When lid was opened, some nigh liquid for example because the effect of surface tension of liquid is attached near the drop lid, if when having overbalance between pressure in container and the exterior ambient pressure, will go out from splash in the container.So just have near the risk of liquid splash vessel port, or even can splash to the user on hand or the risk on the clothing.If liquid is the liquid that is easy to pollute, Feng Zhuan hair dyeing product particularly, then this shortcoming is particularly evident.
Consider that for this EP-A-0 528 707 is open and proposed a kind of two kinds of products that are used to store, in particular for two bottle packings of storing liquid products, described two kinds of products are separated mutually and just it are mixed in use.This kind packing is used for hair dyeing solution and uses the required oxidizer of hair dyeing solution to store respectively.For adopting " oxidation dye ", in fact need for example hair dye to be added hydrogen peroxide in the moment that spreads upon on the hair by adding oxidizer to hair-dyeing.Therefore be divided in and be more convenient for implementing hair dyeing in two bottles.
Before the unlatching, user's solution of will having hair dyed mixes with oxidizer and also needs shaking ladle bottling to make it to mix usually.Begin the oxidation chemistry reaction this moment and cause generating gas, especially oxygen, described gas will impel the rising of pressure of the inside of a bottle.Be provided with the external screw thread adapter on the top of bottle, the batching ozzle of a closure can be rotated with hermetically on this external screw thread adapter, and the top of the ozzle that can fracture in use, sets up opening, thereby product can be poured on the hair.This broken top can avoid the user by re-using again of top carried out embolism to container, because oxide hair dye can not be preserved after mixing, so this point is necessary.Therefore impelling the user to be about to Packaging Bottle after using hair dye first disposes.
But through finding, since the inner of batching ozzle be pointed and under the surface tension of liquid effect, certainly will be attached with the hair dye drop and usually the user understand the shaking ladle bottling and cause the formation of this drop, so when opening the hair dye drop very near broken place, tip.Therefore, when the user tip that fractures, when opening Packaging Bottle, the most advanced and sophisticated drop of next-door neighbour will certainly cause by splash to the Packaging Bottle outside face, the user on hand, or even in the worst case by splash on user's clothing and cause the risk of nonvolatil stolen goods dirt.If the two kind compositions of the certain moment of user before unlatching to hair dye mix, if for example the user cleans its hair between these two control steps, then this phenomenon is particularly evident.This is because the chemical reaction that produces between two kinds of compositions will cause the rising of pressure and thereby be engraved in the bigger pressure reduction of formation between Packaging Bottle inside and the air environment when opening.
In addition, find that also the broken plug member with very good sanitation performance is always so not wieldy.This is because their mechanical characteristics is too good, so the user has to use cutting knife or scissors, cuts off the tip, and this is accompanied by the risk that the user might be injured or be difficult to open.On the other hand, if the mechanical characteristics at broken tip is bad, then during to processing such as Packaging Bottle such as packing, stacking or transportations, be easy to cause most advanced and sophisticated fractureing.This can cause packing to be undermined the danger that adjacent Packaging Bottle is polluted again, and the product that these Packaging Bottle are contaminated no longer can be sold, thereby will increase loss significantly.

Figure 18 is the longitudinal diagram of another embodiment of the present invention.
The specific embodiment
As shown in the drawing, bottle comprises a bottle 1 and a cover piece 2.Bottle 1 is made of glass or molding synthetic material, and for example has the frustum of a cone global shape such as circular, oval or some other cross sections, and an ozzle 4 that slightly is conical frustum shape is installed near the convex shoulder 3 of the end the top.
The upper edge 5 of ozzle 4 forms its free end, and its other end is connected with convex shoulder 3.Ozzle 4 be hollow and thereby form inside and outside bonded assembly passage 6 with bottle 1.The upper end of the passage 6 on the plane identical with the upper edge 5 of ozzle 4 forms discoid outlet mouthful end 7.Outside face 4a at ozzle 4 forms external screw thread 8.
With the lower surface 10a of the upper wall 10 of sidewall 9 homonymies on correspondingly form circular sharp gasket ring 12, its diameter conforms to the diameter of arris 5, thus the upper edge 5 of described gasket ring 12 and ozzle 4 seals and touches when closure state.
Cross section of each plug part 13 is circular arc and is separated by a slit 15 and adjacent plug spare 13 that described slit is along the whole length extending of plug part 13.Also can change accordingly, be designed to one or more slit 15, only stretch along the partial-length by 13 lower ends, 14 beginnings of plug part in described slit.But, preferably there is a slit to extend to the position of approaching upper wall 10 for the following reason that also will be explained always.
One hole pipe 16 is arranged between plug part 13, and this hole pipe 16 stretches on the whole length of described plug spare 13, and also it can be designed to only along the hole pipe 16 that stretches on the partial-length by 13 lower ends, 14 beginnings of plug part at this.
Separated plug spare 2 and bottle 1 shown in Fig. 1.Described plug spare 13 has corresponding suppleness in the horizontal, thereby the plug spare shown in the figure 13 is in free state.In this free state, the lower end 14 of plug part 13 can in be connected into an imaginary circle, this circle diameter is greater than the diameter of 4 mouthfuls of ozzles end 7.Therefore, if the user unscrews cover piece 2 and with cover piece fully by taking off on the ozzle 4, then be difficult to again cover piece 2 is installed on the described ozzle 4, this be because the diameter of plug part 13 greater than the internal diameter of 6 mouthfuls of ends 7 of passage so.Thereby will impel the user must not reuse cover piece 2 container is covered again.
In the flexible program shown in Fig. 3, plug part 13 is longer than plug spare shown in Figure 1, for keeping the lasting elasticity of its constituent material, the lower end 14 of plug part 13 further can be separated, thereby any trial that covers again with cover piece 2 all more is difficult to successfully.
Opposite with such scheme, the lower end 14 of plug part 13 flushes with the lower end of sidewall 9 substantially in the deformation program shown in Fig. 4, and the while has certain interval certainly, thereby can not inlet port end 7 when making it be in free state.If worrying that the user might attempt to use such as instruments such as knife or pliers makes the lower end 14 of plug part 13 and closes, once more container is implemented closedly with cover piece 2, then this flexible program is useful especially.The plug part 13 lower end 14 cut sth. askew, in it radially arris be shorter than its outer radial arris.Therefore, any when attempting that container added a cover cover piece again, in case the end of plug part 13 contact with the upper edge 5 of ozzle 4, then fill in part 13 certainly will be radially outward also so hold 7 outside slippages at mouth.
In flexible program shown in Figure 5, cover piece 2 comprises an independent plug part 17, but the part below it is divided into several branches 18, described branch 18 by another branch to lower bifurcation, thereby make its lower end 19 similar with the lower end 14 described in the above-mentioned flexible program.Also can associate simultaneously and use a plug part 13 and a plug spare 17 that has two branches 18, maybe can also use two plug parts 17 that have two branches 18 respectively.
In flexible program shown in Figure 6, cover piece 2 comprises the plug spare 13 that its length is very short, and its length is shorter than the axial length of cover piece significantly, and the mode that adopts degree of tightness to cooperate between plug part 13 connects a sag pipe 26.Sag pipe 26 has the cylinder global shape, and its upper end 26a forms at a certain angle and is arranged in the hole pipe 16 of 13 of plug parts, and its lower end 26b surpasses the lower end 9b of sidewall 9.Therefore when closure state, the lower end 26b of pipe 26 is not arranged in the passage 6, but in bottle 1 in-to-in district 1a.During unlatching, in case the sealing that forms between the upper edge 5 of gasket ring 12 and ozzle 4 is disengaged, and before screw thread 8 and 11 is totally released, high pressure gas in bottle 1 inner area 1a are promptly revealed, be upward through the inside of pipe 26, to fill in part 13 separated slits 15 through one or more, between ozzle 4 and sidewall 9, return downwards then.Cut fluted upper end 26a be used to guarantee pipe 26 inner with at least one slit 15 between be communicated with.If have fluid drips in passage 6, then guaranteed not can be owing to the equilibrium of inside and outside pressure in the decompression of the gas before screw thread 8 and 11 is totally released, and the splash phenomenon occurs.When bottle during in normal make position, cover piece 2 is topmost, and the lower end 26b of pipe 26 must be located on the liquid levels of holding in the bottle 1 and the drop or the height between the partially liq that are easy to be trapped in owing to the surface tension of liquid effect in ozzle 4 passages 6.Thereby can realize gaseous emission, do not reveal and liquid can not occur.
According to a flexible program, can also associate and use plug part 13, described plug spare takies very little radial space, is arranged in the pipe 26, and the upper end 26a of pipe is cut with groove, thereby realizes gas communication.
In the step of shown in Fig. 7 to 12 container being added a cover.What these steps of adding a cover related to is the step of product at the originating firm workshop, in fact is not the customer capabilities of staying at home.
As shown in Figure 7, cover piece 2 is above bottle 1, and plug part 13 is in free state.Then by downward moving axially, as shown in Figure 8, cover piece 2 is moved to mouth end 7 places that approach ozzle 4.As shown in Figure 9, utilize an instrument 20 to make plug part 13 and closing, thereby the imaginary circle diameter that is connected in it is less than the internal diameter of passage 6 openings 7.Described instrument 20 can be the form that is made of several pawls, and each plug part 13 or each branch 18 are equipped with a pawl at least, and each plug part 13 or branch 18 are radially moved inward.The pawl of instrument 20 can be the form that is similar to the aperture of photographic camera, thereby can promote plug part 13 with the quantity of pawl is irrelevant, makes it to abut in together mutually.
As shown in figure 10, in case employing instrument 20 closely abuts in together plug part 13, then the end by will fill in part 13 is inserted arrival end 7 and is caused slightly inlet port ends of described end 14, then can realize continuous downward axial mobile of cover piece 2.
As shown in figure 11, instrument 20 is removed, and plug part 13 is fixed on the upper part of passage 6.Then recover downward moving axially, be together with each other until screw thread 8 and 11.Rotation cover piece 2 causes screw to be tightened, until realizing that the complete and leak free of cover piece on bottle fixed as shown in figure 12.
The end 14 of filling in part 13 this moment puts in the bottle 1 under the convex shoulder 3.
In the mode of operation of opening cover piece shown in Figure 14 to 17.In container, be equipped with under the situation of liquid to small part, because the drop of the described liquid of effect of surface tension of liquid is attached near the convex shoulder 3.Under the situation of using the hair dye applicator, as long as the user shakes container, two kinds of compositions are mixed, then in fact under any circumstance all can form drop.The more detailed condition of relevant dual compartment package sees also EP-A-0 528 707.The volume of drop 21 will depend on the physicochemical characteristics of liquid certainly, for example its viscosity, its surface tension and water-wet behavior thereof etc.
Adopting under traditional not situation with the cover piece of filling in part 13, drop forms in the upper end of cover piece, directly contacts with the upper wall of cover piece, and the passage in the ozzle that might account for is very most of.
As shown in figure 14, when adopting cover piece 2 of the present invention, drop 21 formation below convex shoulder 2 and plug part 13.Utilize advantage of the present invention, can make drop depart from a mouthful end 7 in the axial direction.
When cover piece 2 was unscrewed as shown in figure 15, described cover piece 2 slightly moved up, and caused gasket ring 12 to separate with the upper edge 5 of ozzle 4 and depressurization.
If when opening, there is the gas under the high pressure of being in corresponding to air environment in the inside of container body 1, then these gases will be by slit 15 and/or by managing 16 in the hole of 13 formation of plug part, then, leak out at screw thread 8 and 11 quilts at last through 13 slits 15 that form between near the plug spare the upper wall 10.Because the drop 21 of the overwhelming majority is in the district of plug part 13 ends 14 radial outsides, thereby the gas of leakage is under high pressure only brought the liquid of a spot of drop in the hole pipe 16 into.In addition, these a spot of liquid certainly will be attached in the slit that forms between the plug part 13 under capillary effect, and the radial dimension in slit is less than the radial dimension of hole pipe 16.This a spot of liquid might be distributed on the inner face of the free surface of plug part 13 and the passage 6 that ozzle 5 forms, and these free surface limit slit 15 and hole pipe 16.Usually hole pipe 16 can be droplet distribution provides most of face.Hole pipe 16 still is used for mechanism that gas is separated by the drop that forms in addition, and described most drops are to go up the hole that forms away from the free end by plug part 13 diametrically and/or axially to manage on the position of 16 lower end and form.The free cross-section that is used for gas leakage is small enough to make liquid a large amount of in this section not hold the degree of being leaked out through this outlet mouth.So can extract the gas of not being with splash liquid.
Therefore the phenomenon that reduces pressure can occur in position shown in Figure 15, still be in engagement at this position screw thread 8 and 11, this engagement remains on cover piece 2 on the bottle 1 and avoids cover piece to be opened by roof pressure, allows gas leakage to go out simultaneously.In case realize decompression, then continue cover piece 2 unscrewed and direct-axis to taking off cover piece 2, the plug part slips in the passage 6 of ozzle 4 for 13 this moments.Fill in part 13 in the case and form embolism, as shown in figure 13, having dwindled liquid greatly can occupation space in passage 6.
When cover piece 2 during in position shown in Figure 16, as can be seen, a little the remaining drop 21 that is carried by plug part 13 will certainly be distributed on passage 6 walls.During unlatching is moved, the face district of distribution drop will progressively increase.This is because plug part 13 makes the increasing part of ozzle 5 inner faces obtain discharging, stretches between this part fill in part 13 when closure state lower end and its instantaneous position during unlatching is mobile.
Shown in the embodiment among the figure, the inner face of ozzle 5 slightly is truncate taper shape, and the diameter of mouthful end 7 is less than near the diameter of 6 substrates of the passage the convex shoulder.During described unlatching was moved, plug part 13 was forced to abut in mutually together, and this will reduce in passage 6 idle cross section that can receiving fluids.In other words, the width in gap 15 will diminish, and produce crowding-out effect, and drop is dripped back in the bottle 1.
When mobile end, cover piece 2 separates with bottle 1 fully, the end 14 through port ends 7 of plug part 13.As shown in figure 17, at this moment fill in the shape that part 13 recovers its free states, this moment its horizontal size greater than the size of mouth end 7, thereby can avoid cover piece 2 to be covered again on bottle 1.Therefore as can be seen, the liquid that can not that is contained in openable container in the container is gone out by splash, and this is because the section that any drop is revealed away from high pressure gas.In other words, plug part 13 can make high pressure gas break away from drop 21 and sealing be disengaged the back and at cover piece 2 with before bottle 1 separates fully, can realize the leakage of gas, thereby can realize the very reliable and clean unlatching of container.Even the leakage of gas causes generating a spot of drop, these drops also can be distributed on the face that is provided with for this purpose and can avoid splash.
In the embodiment shown in Figure 18, substitute plug part 13 by an independent protrusions 22, this protrusions takes in ozzle 4 the whole space that forms substantially, and flushes with the lower surface 24 of convex shoulder 25, and it is the footpath of the benchmark corresponding bigger size that makes progress that described convex shoulder need have with the cover piece axle at this.The lower surface of described convex shoulder face and protrusions 22 presents an actual smooth surface, can not form drop on this surface.Usually, have only after the user mixes the hair dye component and shakes, just can on this surface, stay the very thin liquid film of one deck.When opening, very small amount of liquid in the liquid film that only can carry formation that moves up of protrusions 22, and this a spot of liquid certainly will distribute along the inwall of passage 6 during moving, and this names a person for a particular job and further reduces the quantity of the liquid that constantly might be ejected in decompression.
Because above-mentioned advantage of the present invention, thereby can realize making economy and using reliable, clean cover piece and container.Can adopt degree of tightness cooperation or screw to be fixed on the container to cover piece.Thereby the danger that when normal the use, can avoid the liquid splash in the container to go out.In other words, a liquid sealing structure is arranged in the part of passage 6 at least, this structure can avoid liquid holdup in described part and simultaneously gas can pass through this part again, thereby can realize decompression to container.The unitized design of this hydraulic seal of Shi Xianing and ventilation is very useful simultaneously.
Cover piece can also add to be equipped with and avoids or can stop at least fully the reusable mechanism of cover piece on container, this point is disposed described container after using for the first time by impelling the user, thereby can guarantee can only use once the product in the container.At last,, still can make by mold pressing is one-body molded, needn't add any parts container no matter be to cover piece.
