Description
The present invention relates to the integral plastics beverage bottle.Particularly relate to a kind of improved bottle, this bottle has bigger horizontal surface area, and it can be firmly held on the upright position when the perfusion beverage.
Insufficient strength at the bottom of with the main difficulty of plastic bottle carbonated beverages being bottle.Because the pressure of carbonate gas is higher in the bottle, can reach 75 pounds/inch
2More than, so the bottle end of plastic bottle usually outwards bloats, bottle is put in one plane and will be rocked back and forth when it just as one " rocker " as a result, perhaps may overturning.In addition, because bottle outwards protrudes at an end, the volume of bottle increases, and therefore, has reduced the liquid level of beverage, and the customer just may think that bottle do not fill or do not have a good seal.
A kind of way that solves the bloated problem of bottle pucking is hemispherical with making at the bottom of the bottle, lives it with an end saucer that has planar base surface again, and bottle is supported on the upright position.This bottle is commonly referred to as compound bottle.Compound bottle is widely as the bottle of adorning 16 ounces or more carbonated drink.But, because cup with the end, so the cost of material is higher, thus encourage the integral bottle at the bottom of people remove to study the hemisphere bottle that has reinforcement, with the bulging phenomenon that prevents to cause owing to carbonate gas pressure.
In the time of at the bottom of estimating a kind of bottle, should consider several factors.Stability is most important factor.Bottle is empty or all should is stable when being full of beverage.Empty bottle must be sufficiently stable with the state of being kept upright in the bottle charger.If bottle is overturning in transmission course, will influence the efficient of filling material.In order to make bottle keep stable, the diameter of bottle and contact position, held water plane is essential maximum, and is in addition, also essential maximum with the area at the face-to-face contacted bottle of the aerofoil end.
Another factor of evaluation is the intensity of the anti-sudden impact at the bottom of the bottle when bottle fills material.The bottle end, will reduce intensity if any stress cracking, and it is burst easily.The quantity of stress cracking is relevant with the geometric configuration at the bottle end.The stress cracking at the bottle end that bending spring is bigger is than less the lacking of bending spring.
Make the ability of the correct exhaust of die cavity when also having the factor of evaluation that to consider to be blowing mould shaping bottle.Exhaust must be sufficient be formed on the pin that bottle bearing surface contact zone is determined in the leg lower end to guarantee in each leg at the bottom of plastics are blown into bottle fully.
Several integral bottles have been developed.But their bottom structure all has one or more shortcomings.Plastic bottle is when pouring into carbonation liquid, and the bottle end can offset downward.When this situation appearred in existing several integral bottles, the diameter of its bearing surface contact zone and size will reduce, and the stability of result's bottle when pouring into beverage just reduces.
Also there is the little and bending spring problem of smaller of bottle pin in the geometric configuration at the bottle end of several bottles in the past.Therefore, stable inadequately when standing, and be prone to stress cracking, thus reduced the intensity at the bottle end, when being subjected to impacting, easily break at the bottom of making bottle.
These shortcomings at former technology an object of the present invention is to provide a kind of bottle, with respect to certain bottle diameter, have the flat bearing surface contact zone of large-size, therefore, have improved pack into stability after the beverage of bottle.
Further purpose of the present invention provides a kind of bottle, and the skew that this bottle causes because of charging can not reduce the area of bearing surface contact zone.
Another purpose of the present invention provides a kind of bottle that has than the macrobending radius, so that reduce the possibility that produces stress cracking.
Purpose of the present invention can reach by following measure.The invention provides a kind of bottom construction that takes up the bottle that carbonated drink uses, comprise the diapire that extends inwards from the cylindrical sidewall lower ends downward with cylindrical sidewall.One group of bottle leg extends downwards from diapire, and the end of bottle leg is to have the radially flat bottle pin at inside and outside edge.The outer rim of bottle pin forms discontinuous bearing surface, and the diameter of its contact zone only is slightly less than the diameter of cylindrical sidewall.
As further improvement, can make these bottles pin radially inwards and be inclined upwardly, make bottle when pouring into carbonation liquid, the pressure of bottle interior forces bottle pin roughly around its outward flange rotation and remain on the position of level.Owing to be on the level attitude, aspectant area of contact is just bigger between the horizontal surface of bottle pin and support bottle.When bottle charges liquid, just can not reduce the diameter of bottle bearing surface contact zone, and the outer rim maintenance of bottle pin contacts with horizontal surface, so the diameter of its bearing surface contact zone equals the diameter of empty bottle as the bottle of prior art.
The bottle wall part that diapire extends downwards at the bottom of the bottle tilts slightly inwards than the cylindrical sidewall of bottle.In order to make this bottle, this tapering is necessary.By reduce the way of this tapering as far as possible, can make radial distance reach maximum, thereby obtain the diameter of bigger bearing surface contact zone from the center shaft of bottle to bottle pin outer rim.This has just improved the stability of bottle.In addition, the bottom that lower end diameter is bigger can make the plan area of bottle pin bigger than the bottle of prior art.
And by increasing the diameter of bearing surface contact zone, the bending spring at the bottom of can making bottle becomes big, thereby has reduced the stress cracking at the bottle end.
By following explanation and appending claims and more detail knowledge further purpose of the present invention, characteristics and advantage in conjunction with the accompanying drawings.

Describe most preferred embodiment of the present invention below in detail.
Describe most preferred embodiment of the present invention below in detail.
Fig. 1 and Fig. 2 show the plastic bottle made from prior art.One group of level bottle pin 104 is arranged at bottle bottom 102 shown in Figure 1.The bottle pin 104 outward flange (105) be exactly diameter be the outward flange of the bottle bearing surface contact zone of D.Core 106 has sealed the bottom surface of 107 of the inward flanges of bottle pin 104, and protrudes into the bottle wall that the bottle the inside has formed concave outer surface.
When 102 bottle pours into carbonation liquid at the bottom of having bottle, at the bottom of forcing bottle, pressure in the bottle offsets downward, core 106 is moved among the figure on the position shown in the dotted line 108, thereby cause that bottle pin 104 arrives on the position of dotted line 110 around its outward flange 105 rotations approximately, so that bottle just is supported on is corresponding mutually with the inward flange 110 of bottle pin, diameter is on the bearing surface contact zone of d.Because diameter d diameter group D is much smaller, therefore, behind the bottle dress liquid, its stability just reduces.
The bottom construction of the another kind of bottle of producing with prior art as shown in Figure 2.The bottle end 112, have level bottle pin 114 and rib 116, and rib 116 extends transverse on the opposing sidewalls of bottle from the inward flange 118 of bottle pin 114, and links to each other with this sidewall at 120 places.When bottle is empty, the diameter of the bearing surface contact zone at the bottle end 112 extends to outward flange 112 places of bottle pin 114, but, after bottle is filled carbonated drink, 112 offset downward at the bottom of pressure in the bottle forced bottle, make the rib 116 that is originally straight curve shape shown in dotted line among the figure 124 downwards, thereby make bottle pin 114 position shown in the dotted line 126 around its outward flange 122 rotations and among the arrival figure approximately.On this position, the diameter of bottle bearing surface contact zone, the end just only extends to inward flange 128 places of skew back bottle pin 126, so the stability of adorning bottle behind the liquid is than empty bottle difference.
The bottle end of plastic bottle of the present invention,, after bottle poured into liquid, its bearing surface contact zone can not reduce.Fig. 3 shows the plastic beverage bottle with bottom structure of the present invention, and its general shape is shown in 130.This bottle be with the blowing mould forming process by twin shaft to saturated polyester, preferably polyethylene terephthalate (PET) is made, it comprises a single-piece conical top 132, has a flange 134 and spiral bottleneck 136 on the top 132.The 132 hollow bottles of forming by cylindrical sidewall 138 downwards from the top.Sidewall 138 generally is columniform, and it has the straight longitudinal axis 139 by its center.The also bottom of closed bottle 130 is extended from the lower ends downward of sidewall 138 in the bottle end 140.
The bottle end 140, have a diapire 142 that extends downwards, and this section-drawing from Fig. 5 can be seen clearlyer.Diapire 142 begins radially turning-in from the lower end of cylindrical sidewall 138.As shown in Figure 5, the bent flat of diapire 142 directly is a unmodified, and bigger than the radius of cylindrical sidewall 138.The quite little fillet part 144 of radius is used for connecting the upper end of diapire 142 and the lower end of sidewall 138.Diapire 142 ends at the lower end 146 of core, promptly be basically bottle at the bottom of 140 center and intersect with axle 139.Though the bottle end may be protruded a little or be recessed, core in the central generally is a level.
Diapire be broken into one group radially spaced-apart and extend to the wall section of the downward protrusion below the diapire 142 at 146 places, centre, be called hollow legs.These wall sections comprise bottle leg sidewall sections 148 and bottle leg outer wall section 150, as shown in Figure 3.Bottle leg outer wall section 150 has formed the radially-outer surface of hollow legs.As Fig. 3 and shown in Figure 5, bottle leg outer wall section 150 on downward direction with radially turning-in of constant radius.The sidewall sections 148 of bottle leg extends downwards and radially extends inwards from the outer wall section of bottle leg from diapire.The end of bottle leg is a bottle pin 152.Fig. 5 A is the enlarged drawing of the bottle pin of Figure 10.Each bottle pin 152 all is flat, and its shape generally is trapezoidal (see figure 4), and its outward flange 154 is general parallel with inward flange 156.The side 155 of bottle pin 152 radially tilts mutually inwards.Diapire around between hollow legs has formed the inverted V-shape rib that separates hollow legs.
Each bottle pin 152 have one radially inwards with acclivitous plane, make the outward flange 154 of each bottle pin be lower than inner edges 156.The outward flange 154 of bottle pin is adjacent with the lower end of bottle leg outer wall section 150 and by the quite little fillet part of a radius 158 they are coupled together.The outward flange 154 of bottle pin 152 has formed the bearing surface contact zone that diameter only is slightly less than the support bottles 130 of sidewall 138.Because the outer peripheral position of bottle pin as far as possible radially outward, therefore improved the stability of bottle.
After bottle 130 was filled with carbonated drink, the pressure in the bottle forced centre 146 to offset downward the position shown in the dotted line 160 among Fig. 5.Because centre 146 moves down, so bottle pin 152 also moves down and arrive level attitude 162 around its outward flange 154 rotations approximately, like this, the bottle pin just is in and supports on the horizontal surface 163 face-to-face contacted positions of bottle, because the outward flange of contact surface remains on 154, so the bearing surface contact zone can not reduce because of the skew in centre 146, therefore, bottle is filled rear stability and can not reduced.
The angle 157 that bottle pin 152 and Horizontal Branch bearing surface are 163 depends on the size of bottle and the wall thickness of bottle bottom material.These two kinds of factors have determined the side-play amount at the bottle end that internal pressure causes.Have found that, for the bottle of great majority two liters and 16 ounces, angle 157 be about 9 ° just enough.
Except keeping in when skew at the bottom of the bottle the bottle stability at the end, bottle pin 162 and the contact zone on surface 163 have also reduced the vibration of bottle.If when the impact that upright bottle is subjected to was not enough to it is pushed over, it will rock back and forth.This shake to be actually weaken gradually, last bottle is with stop motionless.When bottle pin 162 contacts face-to-face with areal of support, will be bigger to the resistance that shakes than the old soldi on the outward flange 154 that is supported in inclination pin 152.
Another kind of embodiment of the present invention is blow molded into the shape plastic bottle with label 10 expression as in Fig. 6～10.Plastic bottle 10 comprises the conical top 13 that has flange 12 and spiral bottleneck 18.Plastic bottle 10 also has at the bottom of hollow cylindrical sidewall 14 and the integral bottle 16.
As shown in figure 10, the bottle end 16, comprise a diapire that extends from sidewall 14 downwards, and diapire has top 20 and is the arch lower part 30 that radially bends inwards downwards.The core 28 at 16 center at the bottom of diapire ends at and is actually bottle.
Diapire is broken into one group of wall section that extends to the downward protrusion below the diapire, is called hollow legs 26.These wall sections comprise bottle leg sidewall sections 32 and bottle leg outer wall section 33.Bottle leg outer wall section 33 forms the radially-outer surface of hollow legs 26.As shown in figure 10, bottle leg outer wall 33 radially evenly tilts on downward direction inwards.The bottle leg ends at (see figure 10) on the flat bottle pin 25 that concentrates on the core 28.When bottle was sky, bottle pin 25 was in position as shown in phantom in FIG. radially inwards with downward-sloping.When bottle had been filled with carbonated drink, the position of bottle pin then was among the figure shown in the solid line 27.Fill beverage, bottle pin 25 approximately when its outward flange 24 rotates to position shown in 27 when bottle, a bottle pin just is in and horizontal surface 29 face-to-face contacted positions.
In two embodiment of the invention described above, spaced-apart bottle pin radially outward as much as possible, so there is bigger plane surface to form the bearing surface contact zone.The outer wall section of bottle leg tilts inwards on downward direction or is crooked, so bottle takes out from mould easily.Owing to reduce this inclination or bending as far as possible, so the diameter of the discontinuous bearing surface contact zone of being made up of bottle pin outer rim only is slightly less than the diameter of bottle cylindrical sidewall.In addition, the interval between the bottle pin makes it compare with many bottles with the prior art manufacturing, and the radius of the sweep at the bottle end is bigger, so be reduced to the possibility of having eliminated bottle end generation stress cracking.Have found that two kinds of bottles for 2 liters and 16 ounces adopt 5 bottle pin best, can obtain the radius of bigger bottle pin and bigger bottle end sweep.
Hollow legs is that the plastics by diapire blow out downwards from diapire.The terminal of bottle leg is actually the supporting plane contact zone by the diapire projection.The bevelled contact zone transfers to form and the contacted coplane of the horizontal surface district of supporting bottle at the internal stress effect backspin of bottle.
The invention provides a kind of blowing mould shaping integral plastics bottle that has at the bottom of the self-supporting bottle.A diapire that extends downwards from the side wall lower ends of bottle is arranged at the bottom of this bottle.One group of bottle leg has extended to form the hollow legs of being with flat bottle pin downwards from diapire, and the bottle pin is from the upwards inclination inwards of outward flange of bottle leg.When bottle was filled with carbonated drink, the bottom at the bottom of the internal pressure in the bottle forces bottle offset downward, and the bottle pin then rotates on the level attitude that the coplane bearing surface contact zone by the supporting bottle limited.This skew can not reduce the diameter of bottle bearing surface contact zone, therefore can not reduce the stability of bottle when irritating liquid.In addition, the radius of sweep was bigger when the bottle end was shaped, so reduced the quantity of bottle stress cracking at the end, therefore, had improved the intensity at the bottle end, thereby had reduced the possibility of bottle explosion.
Should be understood that the present invention is not limited to detailed structure and the method that illustrates in the above-mentioned and diagram, the spirit and scope of the present invention of defined in claims can be carried out various changes and modification only otherwise below breaking away from.
