Abstract
The invention relates to a lightweight bottle port which comprises a bottle port main body and thread, a safety ring and a supporting ring which are successively arranged on the bottle port main bodyfrom top to bottom. The whole height of the bottle port main body is 17mm, the top end width of the thread is 0.8mm, and the thread bevel is 20 degrees/20 degrees. A flange is arranged under the safety ring. By adopting the technical proposal, the lightweight bottle port has the advantages of ensuring the normal bottle blowing and filling quality, reducing the weight and saving cost.
Description
Technical field
The present invention relates to a kind of bottleneck that is applicable to beverage bottle, relating in particular to material is the beverage bottle bottleneck of polyethylene terephthalate.
Background technology
Container package bottle, especially material are the beverage bottle of polyethylene terephthalate, and its bottleneck all adopts the bottleneck moulding of traditional model PCO1810 beverage bottle mostly.As shown in Figure 1, this beverage bottle bottleneck is made of bottleneck main body 100, screw thread 200, guard hoop 300 and support ring 400.The characteristics of this bottleneck are: screw thread 200 is for disconnecting design, so just make when the turn bottle cap, the gas that is contained in the beverage, can discharge in advance from the screw thread gap, and can not cause one of liquid beverage to gush, adopted by vast drink manufacturing merchant so plant the design-calculated bottleneck always, and used till today.As shown in Figure 2, in order to satisfy requirement of strength, this bottleneck whole height is 21mm, and screw thread 200 top width are 1.2mm, and the upper and lower oblique angle at screw thread tangent plane oblique angle 201 is respectively 20 ° and 10 °, and guard hoop oblique angle 301 is arc transition.But along with the rise of recent world market crude oil price, drive the raw-material rise in price of PET, above-mentioned traditional bottleneck materials just seem that a bit too much for cost-cutting, energy savings presses for and reduces the bottleneck materials thereupon.
Summary of the invention
Technical matters to be solved by this invention provides a kind of when guaranteeing normal bottle blowing and filling quality, can reduce the beverage bottle bottleneck of materials, saving cost.
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme:
A kind of beverage bottle bottleneck, screw thread, guard hoop and the support ring that is positioned at successively on the bottleneck main body constitutes by the bottleneck main body, from top to bottom, it is characterized in that: described bottleneck main body whole height is 17mm, the threaded tip width is 0.8mm, screw thread tangent plane top rade is that 20 °, time oblique angles are 20 °, and described guard hoop below has flange one.
Described flange begins downward extension from the guard hoop lower surface.
Described flange length is 1.5mm, and thickness is 2mm.
Described guard hoop has the oblique angle, and this guard hoop oblique angle is a straight transitions.
Described guard hoop angle of bevel is 45 °.
Described screw thread is the open circuited discontinuous extension screw thread in interval.
Adopt technique scheme, compare prior beverage bottle bottleneck, bottleneck main body whole height is dwindled, also dwindled the width of screw thread, so just saved the materials of bottleneck relatively; Influence follow-up bottle blowing and filling quality for fear of bottleneck because of the minimizing of materials, increase by one flange below the bottleneck guard hoop, so just increased bottleneck wall thickness herein, guarantee bottle base in heating links such as bottle blowing and can, bottleneck is indeformable; Because the minimizing of bottleneck height, certainly will shorten whorl of bottleneck length, what the shortening of length of thread will influence bottleneck and bottle cap cooperates dynamics and seal quality problem, in order to address the above problem, the upper and lower oblique angle of the tangent plane of screw thread is increased to 20 degree/20 degree by original 20 degree/10 degree, the increase of screw thread tangent plane angle of bevel has improved the cooperate dynamics of screw thread with bottle cap, makes bottleneck cooperate closelyr with bottle cap, avoids sealing quality problems occurring.In addition, further the oblique angle with guard hoop is designed to straight transitions, has further reduced the materials of bottleneck.
Therefore, when beverage bottle bottleneck of the present invention has the normal bottle blowing of assurance and filling quality, the advantage of can reduce grammes per square metre, saving cost.
Description of drawings
The present invention is described in detail below in conjunction with the drawings and specific embodiments:
Fig. 1 is existing beverage bottle bottleneck structure scheme drawing;
Fig. 2 is an A place enlarged diagram among Fig. 1;
Fig. 3 is a Facad structure scheme drawing of the present invention;
Fig. 4 is a structure scheme drawing of the present invention;
Fig. 5 is a B place enlarged diagram among Fig. 4.
Among the figure:
100, bottleneck main body 200, screw thread 201, screw thread tangent plane oblique angle 300, guard hoop 301, guard hoop oblique angle 302, guard hoop lower surface 400, support ring 500, bottleneck upper surface
The specific embodiment
As shown in Figure 3 and Figure 4, beverage bottle bottleneck of the present invention, screw thread 200, guard hoop 300 and the support ring 400 that is positioned at successively on the bottleneck main body 100 constitutes by bottleneck main body 100, from top to bottom.
Wherein, screw thread 200 is the open circuited discontinuous extension screw thread in interval, and such helicitic texture makes when the turn bottle cap, and the gas that is contained in the beverage can be discharged in advance from the screw thread gap, and can not caused one of liquid beverage to gush.Bottleneck main body whole height is 17mm, screw thread 200 top width are 0.8mm, and as shown in Figure 5, screw thread tangent plane top rade is that 20 °, time oblique angles are 20 °, bottleneck upper surface 500 is 11.2mm to the height of guard hoop lower surface 302, and guard hoop 300 is 4.04mm to the distance of support ring 400.Also have flange 600 below guard hoop 300 one, this flange 600 extends downwards from 302 beginnings of guard hoop lower surface, and length is 1.5mm, and thickness is 2mm.Again as shown in Figure 4, guard hoop oblique angle 301 is a straight transitions, and angle is 45 °.
Adopt technique scheme, this beverage bottle bottleneck has following characteristics:
One, the bottleneck whole height dwindles, and reduces the width of whorl of bottleneck, and in order to reduce the materials at former bottleneck guard hoop place, makes the guard hoop oblique angle of new bottleneck be designed to 45 degree, has so just saved the materials of bottleneck relatively.
Two, influence follow-up bottle blowing and filling quality for fear of bottleneck because of the minimizing of materials, increase by one flange below the bottleneck guard hoop, so just increased bottleneck wall thickness herein, guarantee bottle base in heating links such as bottle blowing and can, bottleneck is indeformable.
Three, because the minimizing of bottleneck height, certainly will shorten whorl of bottleneck length, what the shortening of length of thread will influence bottleneck and bottle cap cooperates dynamics and seal quality problem, in order to address the above problem, the upper and lower oblique angle of the tangent plane of screw thread is increased to 20 degree/20 degree by original 20 degree/10 degree, the increase of screw thread tangent plane angle of bevel has improved the cooperate dynamics of screw thread with bottle cap, makes bottleneck cooperate closelyr with bottle cap, avoids sealing quality problems occurring.
Through after the above-mentioned improvement, can make beverage bottle bottleneck materials reduce 1.3g, satisfied when guaranteeing normal bottle blowing and filling quality, reduce grammes per square metre, save cost.
But, one skilled in the art would recognize that the above-mentioned specific embodiment is exemplary, be to be the restriction that this patent is comprised scope in order better to make those skilled in the art can understand this patent, can not to be interpreted as; So long as according to spirit that this patent discloses done anyly be equal to change or modify, all fall into the scope that this patent comprises.
