The specific embodiment
With reference to Fig. 1, Fig. 1 shows the plastic bottle as the typical example of container of the present invention, and this bottle has entirety 1 oral area representing at an upper portion thereof.The below of oral area 1 is connected to bandy shoulder 3.Shoulder 3 is connected to main part 5, utilizes the lower end of bottom 7 sealing main parts 5.
As understood from Fig. 1, on the outer peripheral face of oral area 1, form screw thread 10 and lid engage with this screw thread 10 by the mode of screw thread.Below screw thread 10, form week-like protrusion 11.Although not shown, TE band can be set in the lower end of the lid assembling by the mode of screw thread.TE band produces the not stolen evidence opening with engaging of week-like protrusion 11.That is, if operculum is Kaifeng, TE band remains in vessel side in the mode separating with lid, and this allows ordinary consumer know that lid was once broken a seal.
Large diameter support ring 13 is formed on the foot place of container finish 1.Can be by utilizing support ring 13 to keep and transfer cask.
With reference to enlarged drawing and Fig. 1 of Fig. 2, the horizontal recess 17 of ring-type or arcuation is formed between the upper end 10a of screw thread 10 and the upper end 15 of container (bottle).Namely, side wall surface 19 vertically stretches (stretch) downwards from the outer peripheral edges of the upper end 15 of oral area, and this side wall surface 19 is continuous at the upper wall surface 17a of intersection point X place and horizontal recess 17.
In the present invention, from preventing the viewpoint of liquid drippage, importantly: the upper wall surface 17a of horizontal recess 17 is 80 degree to 150 degree with respect to the angle θ of vertical direction, be preferably 90 degree to 150 degree, particularly preferably 90 degree are to 120 degree.The in the situation that of in angle θ drops on above-mentioned scope, when tilt container is when pouring out the liquid that is contained in container, this liquid can be as shown in Figure 3 wandered side wall surface 19 from the outer peripheral edges of the upper end 15 of oral area.But in this case, liquid is cut off and makes at this part place the power vanishing of liquid pushing and pressing wall at be bonded together part (intersection point) the X place at place of the upper wall surface 17a of side wall surface 19 and horizontal recess 17., liquid separates with wall of container and separates and fall with container finish 1.In the time that container almost starts pouring liquids under upright state, or particularly in the time starting to pour out the liquid that is contained in container or when the liquid that is contained in container is poured out in end liquid the most easily drip.By forming according to the horizontal recess 17 with above-mentioned angle θ of the present invention, this also allows effectively to prevent liquid drippage in the time starting or finish to pour out content liquid.
Here, recess 17 be level and be not used as screw thread.
If intersecting angle θ is less than above-mentioned scope, in the time being shaped, be difficult to remove metal die.Particularly, if intersecting angle θ is less than 80 degree, even by such as forcing to remove or the means such as post-processing are also difficult to remove metal die.In addition, if angle θ is greater than above-mentioned scope, side wall surface 19 and horizontal recess 17(roof 17a) so gentleness makes liquid not be cut off at intersection point X place continuously.In the time not forming horizontal recess 17, not for cutting off the intersection point X(of liquid, liquid is not cut off) time sets up too.Therefore,, if angle θ is greater than above-mentioned scope or the horizontal recess 17 of formation not, the same with the bottle in Fig. 4, liquid drips along screw thread 10 from side wall surface 19.According to circumstances, the dripping whole bottle of making dirty along the outside face landing (creep down) of bottle portion 5 further.
Container of the present invention should have the shape at intersection point X place sharp keen as far as possible (sharp).For example, desired curvature radius R is not more than 0.5mm.When in intersection point X place chamfering, expect that chamfering C is as much as possible little.If the liquid that intersection point X with large scale rounding, remains on side wall surface 19 is not cut off at intersection point X place in the time finishing pouring liquids, and be back to the inside of horizontal recess 17.Therefore possible that: liquid can pass through horizontal recess 17, wander to the part that forms screw thread 10.
In addition expectation: horizontal recess 17 is formed on as upper/lower positions: this position, as far as possible near the upper end 15 of oral area, is not lost sealing be limited with cover while assembling.Particularly, expectation: the distance L of the upper end 15 from intersection point X to oral area is in the scope of 1.0mm to 2.0mm.If horizontal recess 17 is formed on too low position, in the time that pouring liquids is interrupted liquid residue the amount of side wall surface 19 increase and liquid backflow in horizontal recess 17.As a result, liquid easily flows through horizontal recess 17 to the part place that forms screw thread 10.In addition,, if horizontal recess 17 is formed as the too upper end 15 near oral area, the area of the part contacting with the lid being assembled reduces, and is difficult to stably maintain sealing.
On the other hand, in the time that the distance of the lower surface from intersection point X to horizontal recess 17 is considered to the height h of horizontal recess, for the not specific restriction of the height h of horizontal recess, but desired distance L in above-mentioned scope and screw thread be formed on low position within reason.As shown in Figure 2, together with the lower surface of horizontal recess 17 forms with the upper end of screw thread 10a time, the height h of horizontal recess becomes the distance from intersection point X to threaded upper end 10a.
In addition, in the present invention, expectation: the depth d of horizontal recess 17 is not lost the degree of intensity to container finish 1 greatly.For example, expectation: depth d is in the scope of 0.2mm to 1.5mm.If horizontal recess 17 is not enough dark, can there is the identical phenomenon of phenomenon when not forming horizontal recess 17.Namely, if the liquid of having wandered along side wall surface 19 is even marginally back in recess 17, this recess 17 is easily filled and has been flowed into its inner liquid.As a result, liquid becomes perfusion, and the liquid of having wandered along side wall surface 19 can not cut off at intersection point X place and wander to and form the part of screw thread 10.On the other hand, if this depth d is excessive, the intensity of oral area 1 has reduced at the part place of the horizontal recess 17 of formation, and oral area 1 trends towards easily destroyed.
In addition, from preventing the viewpoint of liquid drippage, expectation: outer peripheral edges (part of the contact side wall) Y of the upper end 15 of oral area has the angle shape that approach right angle the same as above-mentioned intersection point X.But this part and the inside face close contact of lid that is mounted to oral area, affected sealing, this part can also contact with the people's who attempts to drink mouth in addition.Therefore, this part Y can have the curved surface for suitable circularity the same with known vessel.This is because according to the present invention, has effectively prevented liquid drippage due to the formation of above-mentioned horizontal recess 17.
Above-mentioned explanation and Fig. 1 to Fig. 5 example when be formed between threaded upper end and the upper end of oral area when horizontal recess is relevant.But, as shown in Figure 6, even if the present invention has also presented the effect that also can prevent liquid drippage by the horizontal recess of formation in screw thread.But in this case, the upper wall surface of horizontal recess is 80 degree to 150 degree with respect to the intersecting angle θ of vertical direction, is preferably 90 degree to 150 degree, particularly preferably 90 degree are to 120 degree.
In addition, in this case, although specifically do not limit for the height h of horizontal recess 17, expect that screw thread is not formed on too top position and maintains suitable distance by screw thread.
Fig. 1 to Fig. 6 shows the example in the time that the present invention is applied to plastic bottle.But, as long as formed, threaded oral area being set, the pattern of container of the present invention is not limited only to bottle, but also can be applied to flask and the bag-like container with wide mouthful.The shape of container of the present invention is not specific restriction also.
The material of container of the present invention is not limited to plastic material and can is glass or metal.But, can easily be formed as meeting the viewpoint of above-mentioned condition from horizontal recess 17, be contemplated to be plastic material.
The present invention has improved the anti-drippage of the liquid of the shape that depends on container finish, and therefore, the present invention does not specify or limit the contact angle between container finish and content liquid.In addition, anti-drippage is not subject to viscosity or the capillary restriction of content liquid.
As plastic material, can use and be used to up to now produce following these materials of accommodating the container that liquid uses: particularly, these materials be such as the polyester take polyethylene terephthalate (PET) as representative and look like polyethylene and polyacrylic polyolefin.In addition, can also adopt following multiple-structure: this multiple-structure is to obtain with above resin combination by using such as the gas barrier resin (gas-barrier resin) of ethylene-vinyl alcohol resin or oxygen absorber (resene or transition-metal catalyst).
According to the present invention, in order effectively to prevent the liquid drippage in the time pouring out content liquid, desirably select shape and the content liquid of the container that can the most advantageously prevent liquid drippage.
As content liquid, in the situation that there is no specific limited, can select those to there is low-viscosity liquid and there is any liquid in full-bodied liquid to those.Namely, soda is dissolved with carbonic acid and is filled to the head space of guaranteeing a constant volume, and noncarbonated beverage products is almost filled up completely and need not stay head space.Therefore, in the time attempting pouring liquids, first container is tilted a little (container is almost upright) with pouring liquids, and liquid is very easy to drip.Even if the present invention can make also can effectively prevent liquid drippage in the time starting to pour out noncarbonated beverage products.
In plastic container, conventionally owing to causing container finish to be formed white for giving stable on heating thermal crystalline (heat crystallization).In the time that content liquid is the colored liquid such as coffee, soy sauce or various juice etc., due to the liquid having dripped, therefore container finish there will be significantly dirty.In this case, the present invention is preventing that aspect liquid drippage be very useful effectively.
In the situation that content liquid is beverage, expect that the present invention is applied to the bottle that volume is not less than 500ml.,, in the case of the beverage bottle of the little volume of about 180ml, customer directly drinks content liquid from container finish as a rule.But along with the volume of container increases, customer is transferred to content liquid in cup and drinks content liquid by gradation, can there is liquid drippage in this therefore.Therefore, also effectively apply the present invention to the beverage bottle of large volume.
Example
This moment, will excellent effect of the present invention be described by means of following experiment.
In this experiment, carry out as described below the anti-drippage test of liquid.
(the anti-drippage test of liquid)
By only changing the oral area of formation screw thread, the PET bottle of the volume of 500ml is used as to sample plasma bottle.Each bottle is filled with the coffee { viscosity in 25 ℃: 10mPaS(B type fluid meter) } of 498ml as content liquid.
Based on the operation of staff pouring liquids, record the position of center of gravity and angle of inclination as data at every turn.By using fixture (the 6 axles-controlled machine people who is manufactured by Kabushiki Kaisha Yaskawa Denki), each sample is moved and rotate to utilize eyes to observe the state of liquid drippage.The sample that makes liquid wander to the part that forms screw thread is be evaluated as × (bad), and the sample that cuts off liquid at intersection point X place is be evaluated as zero (good).
