, Description:FIELD OF INVENTION
The present invention is related to a polyethylene terephthalate (PET) bottle and more particularly an improvement in the construction or structure of the polyethylene terephthalate (PET) bottle.
BACKGROUND OF THE INVENTION
In general, PET (polyethylene terephthalate) is a packaging medium for a wide variety of liquid food products such as edible oils, syrups, mineral water, alcoholic beverages, juices, and honey. PFA Act of India has approved PET is suitable for the packing of food and pharmaceutical products. It has now been adopted for storing all types of foods. Mineral water and soft drinks account for a major share of the total demand. Others include processed foods, edible oils, and sauces. Kitchen containers are another major usage center. In India, PET started being used in a perceptible way only very recently.
PET preform has a large demand for the manufacturing of PET bottles for food and Pharmaceutical companies. The size of the container-produced ranges from 50 ml to 150 ml which is further used for making required size blow molded bottles. It is easily expanded by compressed air with a specific temperature and does not react with acid or alkali. PET Preform has a large demand for the manufacturing of PET bottles for the food and pharmaceutical company. The current worldwide demand for PET for packaging is approx 5.5 billion pounds.
But the size of the preform needs to be adjusted to achieve some of the technical improvements in the bottle construction. We can see some of the inventions that address some features of the PET bottle, in US20020182292A1, where a confectionery in the shape of a soda pop bottle having a top portion, a lower portion, a flowable confectionery disposed within the lower portion, and hard candy or coatable item extending from the upper portion into the lower portion to dip into the flowable confectionery.
In US20040069736A1, molded plastic container for carbonated and non-carbonated beverages. The plastic container includes an upper mouth-forming portion, a cylindrical sidewall portion and a lower base-forming portion. The upper mouth-forming portion includes a non-circular anti-rotation flange adapted to at least partially inhibit full rotation of the container as a cap is inserted on the container. The anti-rotation flange typically has an outer perimeter shape of a heptagon. The lower base-forming portion can include a variety of different configurations.
In US129652, figure l of the drawing shows a side view of a bottle constructed as above described. Fig. 2 is a section of the upper part of the neck and head of the same. Fig. 3 is a transverse section taken through the line xy, Fig. l In these figures, a is the glass ball b, the ring of vulcanized India rubber, cork, or other elastic material placed in a groove, c, around the interior of the mouth; d d, the contraction at the lower part of the neck; and e e, recesses for the ball to be in while the contents of the bottle are being poured out. It will be seen that the lower part of the neck is contracted from two sides only, so that at this point the bottle is of an oval form in section, as shown l at Fig. 3. The passage between the interior of the bottle and the neck can thus never be closed by the ball-stopper, and therefore no difficulty will be experienced in filling the bottle. The drawing shows the body of the bottle to be shaped like an ordinary soda-water bottle, but it may be of any form desired.
Article Codd (Marble-In-The-Neck) Soda-Water Bottles, Then and Now explains some of the soda bottles with Codd’s words as (Fig. 7) of the Drawings show various views of a bottle furnished with an internal ball stopper ‘a’ which is to be held up by the pressure of air or gas within the bottle against an elastic ring ‘b’ placed in a groove formed around the interior of the head. The lower part of the neck of the bottle is also contracted at ‘c’ as described in the Specification of a former Patent granted to me to prevent the ball stopper from falling into the bottle when it is pressed back from the elastic seat ‘d, d’ are the inclined projecting ridges formed along the inside of the neck of the bottle one on either side; the molds in which the bottles are blown have suitable projections formed in them to produce these internal projections in the neck at the time when a bottle is blown in the mold.
But still, there are so many improvements are required to construct the Pet bottles that can be achieved only in glass bottles.
OBJECTIVES OF THE INVENTION
The main objective of the invention is to provide an improvement over the PET bottle construction, particularly the body and neck portions of the PET bottle.
Another objective of the invention is to provide a set of deep-grooved notches convergences towards the axis of the bottle below cylindrical neck portion of the bottle to hold cylindrical closure ball almost 1800.
Another objective of the present invention is to provide a cylindrical neck portion of the bottle to hold a cylindrical closure ball, - a trapezoidal stadium-shaped profile having an ovoid top shoulder to connect the neck portion, and - a hemispherical rigid un-stacked material cylindrical body of the bottle with corrugated a set of corrugated base foots leaning inwardly,
Yet the objective of the invention is to provide a set of deep-grooved notches, trapezoidal stadium-shaped profile, hemispherical rigid un-stacked material cylindrical body from a modified preform having optimum mass or weight value stretched.

SUMMARY:
The construction of the bottle is made as shown in the embodiment to make functional requirements to hold and pack the contained fluid on it. The neck of the blown bottle is to made to locate the peculiarly designed cap on it, to make the closure of the contained fluid, and make filling simple, massively over by the automated machine. In the bottle, there is ovoidal blended curvature to attain the functional requirements such as to hold, swift transfer of fluid, and to ensure forced tampering while consumption. The holding of the closure ball on the recces is done by narrowed grooves located and slightly inclined downwards and nearer to the neck of the holding chamber below which the closure ball is not allowed to move and while consumption of the contained fluid. The closure ball is seated on the narrowed grooves enabling the user to drink the fluid tilting more than the vertical axis of the bottle. The bottle is made below the ovoidal neck holding chamber in such a way to resist the locating ball and allow the contained fluid inside the bottle to transfer in a faster manner via a slitted arrangement. The base is made in such a way to resist the shock load while dropout impact and transfer the forces around the contained fluid to minimize the damage of the bottle while transportation. The corrugated arrangement is made at the base of the bottle and slightly inward to hold its impact force.

DETAILED DESCRIPTION OF THE PRESENT INVENTION
Referring now to the drawings wherein the showing is to illustrate preferred embodiments of the invention only and not to limit the same, From Fig 1, it is an improved structure of PET bottle were the most commonly used packaging for storing carbonated and non-carbonated beverages in PET containers. To produce a single PET bottle compared to aluminum cans or glass bottles for packaging consumes less energy. Less energy also translates into smaller emissions, which nowadays plays a vital role from an environmental point of view.
There are so many structures of PET bottles have available, but the proposed improvement is not an obvious technique and he person who is skilled in the art would appreciate the improvements in the foregoing illustrations.
It is an important embodiment in the improvement technique that the neck portion in the bottle, the major problem while in the case of the reheat stretch blow molding process. It requires the uniform heat around the preform while blowing off it, for that we need the preferential heating system to carry out the elongation of the material and the crystalline material that takes more attention while heating of the preform and uniform distribution of the materials while blowing. This plays a vital role in the strength of the bottle density and uniform cross-section at each stage. Apart from the design and shape of the bottle the blow parameters such as stretching ratio, temperature, pressure, the velocity of the blown air, have the significant formation of qualitative bottles.
It is another important embodiment in the present invention is the preform is made as per the requirement that allows the skilled persons to improve the structure of the PET bottle while blowing, the terminology of the preform is changed for the functional needs to carry out the uniform density and wall thickness bottles at the time of blowing operation.
Yet in another aspect, the preform is made on the relation that the inner diameter of the neck which is equal to the diameter of the mouth Dm as per the Fig 5 . Below the neck there is a convergence portion to which is done below the notch inner diameter Dn. The notch diameter is always kept smaller than that of the closure Ball diameter Db. The preform outer diameter Do is always kept in such a way, which is not touching the mold cavity and notch inner radius Dn. (DoDb>Dn……….…………………………………………………………………….………Eq-1
DoDs………………………………………………………………………….……………Eq-2
Where,
Dm- Mouth Inner diameter.
Db- Closure Ball diameter.
Dn- Notch inner radius.
Do- Preform outer diameter.
Ds- Stretchrod diamter.
The bottle length for the narrow down neck bottle such as goli soda is lesser when compared to that of the holding neck, so there is a narrow stretching arrangement is needed to obtain the bottle in a crystal clear formation with uniform wall thickness. For that the specially designed stretch rod to achieve the desired stretch length as well enough strength to stretch the perform at the plastic stage. so the stretch rod is designed with a narrowed taper towards the stretching tip in such a way to obtain the clear bottles. The modified stretch rod for stretching of the preform at the time of blowing is shown in the figure3-
Fig 2 illustrates the construction of PET bottle having stadium shaped trapezoidal portion were making a narrow down stadium shaped contraction (1.7) below the neck portion, a flow kinetic arrangement is made on the wall without stacking of the material at the converged stadium shape slitting arrangement the profile of mold design is made in such a way that the operating parameters such as stretching followed by clamping, pre-blow, blow and ejection of blown bottles from the mold during the blowing operation are done as per the figure 3 shown according to the requirements that the stretch rod is introduced into the mold cavity initially stretches the preform to a uniform wall thickness less than the diameter of the size of the preform shoulder which enables the preform to blow smaller than the diameter of the preform while blowing. There is an ovoidal-shaped neck region (L2, L3, L4) which is formed initially after stretching of the preform, the bottle is blown afterward, so the blowing of clear and uniform wall thickness on the wall of the bottle is obtained while blowing. Based on this the solution of Unstacked material flow is achieved because of the lesser stretching of the preform while blowing than normal preform. Due to the lesser diameter under the preform neck and long body preform design. So the flawlessly finished uniform density bottle is achieved. The notched profile (1.5) below the neck of the container is made slightly toward the axis of the blown bottle. Which enables the formation of the notches clearly and rigidly Below which the stadium-shaped profile (1.7) is made in a trapezoidal shape having its radius (R1, R2) for even flow of the material towards the bottom of the preform. A hemispherical arrangement (1.8) is connected to the rest of the bottle body in a cylindrical portion (1.9). At the bottom-most portion, a corrugated arrangement of foots (1.11) which is slightly lean inward of the bottle which resists the shock. Above the foot, the stepped arrangement is provided to hold the label which is affixed while automating it.
From Fig 3 it is an important embodiment in the invention that modification of preform to arrive at the present invention is explained
Stage 1
PET / PLA Granules to make a customized preform.
Stage 2
Manufacture of preform in injection molding which is peculiarly designed to blow.
Stage 3
Peculiarly designed mold for converged deeply grooved blowing.
Stage 4

Nomenclature of preform and mold
L1-Notch outer Diameter at the mold
D1preform Diameter at Section A-A
L2 Stadium shaped Mould Distance
D2 Ball Diameter (Closure Ball)
Preform Relation to mold cavity:
D1 = 0.95 L1…………………………………………………………………..Eq-3
L2=1.001 to 1.2 D1…………………………………………………………………….…..Eq-4
D2>L2 …...Eq-5
The preform is specially designed in such a way to carry out the bottle to be made stronger. The preform is made narrow down below the neck and it is being narrow-down before it reaches the notch on the die cavity. It should be narrow-down at constant diameter or slightly taper towards the tip of the preform. At section A-A, it is kept maintained diameter D1= 0.95 L1. While at section B-B the length between the narrow point on the die cavities is maintained at a distance of L2 which is greater than the preform dimension (1.001 to 1.2 D1). The diameter of the Lock Ball (Closure Ball) is greater than L2 So that the ball is retained in the holding chamber itself.
Hence the conditions are satisfied, so that the preform is stretched in a biaxial direction while blowing, so there is no contact in-between the preform and mold cavity, hence the clear uniform material flow without stacking of material.
The preform is made topologically interconnected while making preform algebraic calculations are made according to the complex shape required.
Below the neck of the bottle design, the notches are provided at a distance and angle as per our requirement.
Advantages of the proposed improvement in the construction of the PET bottle:
1. The PET bottle is blown lower than that of the neck diameter.
2. Peculiarly designed preform to obtain the blowing in flawless finish for the complex curved bottle.
3. Angular Notched arrangement (1.5) to hold the ball while consumption of the fluid until it is turned around 180 degrees.
4. The narrow-down portion of the bottle has uniformly distributed flow kinetics.
5. Stiffened trapezoidal stadium arrangement (1.7 and (1.8) with crystal clear and uniform wall thickness in the area is achieved to retain the closure ball.
6. Stretch mechanism is specially designed to stretch the preform in a narrow mould cavity.
7. Bump arrangement to hold the pressure during development during the impact force on the container wall.
Fig 4 illustrates the diameter of the stretch rod and the diameter of the Narrow down stretch portion. Where D2 is the diameter of the closure ball does not show which is greater the diameter of the ovoidal stadium shape so that the travel of closure ball will be restricted between the trapezoidal stadium to the mouth or cap portion of the bottle.
Fig 5 illustrates the top view of the proposed improved structure of the PET bottle, having Dm, Mouth Inner diameter, Db- Closure Ball diameter, Dn-Notch inner radius from which it is well understood that the relationship of the above is Dm>Db>Dn, so that the closure ball is stopped at deep grooved notch convergence portion (1.5) and in the trapezoidal portion or above the trapezoidal portion (1.7) and is restricted to come out from mouth inner diameter.
From the Fig 1-5 it is well executed that the proposed invention containing improved construction of the PET bottle, the overall complete structure of the bottle can be shown in the figure 6 where an improved structure of polyethylene terephthalate (PET) bottle blow-molded from a preform, wherein the improvement in the structure consisting of, a set of deep-grooved notches convergences (1.5) towards the axis of the bottle below cylindrical neck portion of the bottle to hold cylindrical closure ball, a trapezoidal stadium-shaped profile (1.7) having an ovoidal top shoulder to connect the neck portion, and a hemispherical rigid (1.8) un-stacked material cylindrical body (1.9) of the bottle with corrugated a set of corrugated base foots (1.11) leaning inwardly, wherein the trapezoidal stadium (1.7) shaped profile having ovoid bottom shoulder connects the un-stacked cylindrical body of the bottle (1.9), and preform has optimum mass or weight value stretched to form the improved structure of polyethylene terephthalate (PET) with a uniform wall thickness bottle having deep-grooved notches, trapezoidal stadium shaped profile having top and bottom ovoid shoulder, un-stacked cylindrical body. The deep-grooved notches hold the cylindrical closure ball up to 1800 and stadium-shaped trapezoidal profile (1.7) ovoid top and the bottom shoulder tapers inwardly to connect cylindrical neck portion and a cylindrical body portion (1.9), wherein the optimum mass or weight range of the preform is from 14 grams to 18 grams.
