DETAILED DESCRIPTION OF THE INVENTION The set of design engineering, technology and geometry of the funds for pet plastic packaging by blow (Propeller Performance Funds) with the specifications that we indicate in the present point, present an evolution of a bottom that solves the handling of preform with high Recycling percentages up to 70%, with a 600mm bottle, within specifications in all laboratory tests, providing the opportunity to perform optimal processes with a global biorentation of the material in critical areas of the bottom, mainly in the push-up (central background point). These specific measures of the design and geometry of the funds for pet plastic packaging by blow (Propeller Performance Funds), achieve an excellent result in the performance in stress cracking tests (stress cracking), fall impact and internal pressure, very above the specifications required by the MAP (approved plan), as well as the high percentage of recycling reaching up to 70% in plastic bottles "pet" (polyethylene terephthalate). The design, geometry, technology and measurements of the push-up (center point of the bottom), which due to its low and distant height with reference to the final surface of the Petals improves the stability of the bottle and helps a better distribution of the base material. Next I will specify to which corresponds each one of the numbers that appear in the figures of the bottom for container of plastic pet by blown (Bottom Propeller Performance).

In Fig. 1 we can see the bottom from the top view where you can see the difference between the sections and the distance within the transition zone, which is reduced as much as possible, without losing structural strength as a finished product.

In Fig. 2 we can see the bottom from the bottom point of view where the different points that make up the same are described (1) corresponds to the central diameter of the bottom, defined in a dimension of 0.327"evaluated taking into consideration an adequate space so that its five reinforcements are deployed and end in the periphery of this, (2) corresponds to the reinforcement angle, defined in a dimension of 16.31 degrees, evaluated in such a way that the development of the reinforcement is adequate for a good formation and its structure in the upper part, be able to form tangency with the bottom connection diameter; (3) corresponds to the support width, defined in a dimension of 0.670", evaluated taking into account the ideal formation of a background petal, same as All of their radii make possible the correct formation of the bottom shape in the blowing process; (4) corresponds to the width of reinforcement, defined in a dimension of 0.312", dimension required to have the formation and result of the reinforcement angle and the compliance of this, points (5) and (6) correspond to the radius of reinforcement, defined in a dimension of 0.291", dimension evaluated in conjunction with the reinforcement in general, and in proportion to the diameter of the connection with the bottom, to define between both, both the width of the support and the width of the reinforcement; (7) corresponds to the width of petal contact, defined in a dimension of 0.155", evaluated by CAM system (machining design software), said contact width that in relation to its base diameter, will define stability and capacity to withstand the various destructive tests applied to containers of this type; (8) corresponds to the diameter of connection with bottom, defined in a dimension of 2,834", evaluated to obtain in containers of 600 ml capacity, a result in diameter of 71.5 mm.

In Fig. 3 we can observe the bottom from the lateral point of view which is described in the following points, (1) corresponds to the diameter of connection with bottom, defined in a dimension of 2,834", evaluated to obtain in containers of capacity 600 mi, a result in diameter of 71.5mm, (2) corresponds to the height of greater, defined in a dimension of 0.941", own evaluated dimension for funds in capacity of 600ml; (3) corresponds to the largest petal radius, defined in a dimension of 1470", evaluated in conjunction with the base radius, bottom height and contact diameter, thus achieving an external petal profile, capable of withstanding both internal pressures , vertical loads and impact tests to which these types of funds are subjected in laboratory tests; (4) corresponds to the petal contact radius, defined in a dimension of 0.291", evaluated taking into consideration that said radius, will be critical both in the process of blowing the bottom, as well as in the majority of the destructive tests of this one, this evaluation is realized by means of CAM systems (software of design of machineries), and tests of simulation in advanced software; (5) corresponds to the dimension of intersection between greater radius and petal contact radius, defined in 1.168", required for the previous construction of the external petal profile, evaluated in consideration of the function to be performed; (6) corresponds to the upper radius Reinforcement, defined in one dimension 0.164", evaluated in consideration of forming the necessary tangency between the reinforcement and bottom connection diameter, allowing in turn, the exact and necessary formation of said connection diameter; Points (7) and (8) correspond to the intermediate reinforcement spokes, evaluated respectively in 0.920 and 0.161", evaluated taking into account, forming tangency and a profile that of rigidity to the support in said area, close to the diameter of the bottom connection; (9) corresponds to the largest radius of support, defined in a dimension of 2.248", evaluated in consideration of forming tangency with central diameter of the bottom and intermediate radii of this, as a fundamental point, it is achieved that the difference in sections defined between the profiles outer support and petal, be relatively one of the other not very drastic in a diameter defined as transition area, being this 50"approximately the diameter of bottom contact; (10) and (11) these points correspond to the construction height of intermediate radii, respectively evaluated at 0.496 and 0.521", respectively evaluated for the development of the intermediate radii; (12) corresponds to the central background height, defined in a dimension of 0.791", evaluated taking into consideration to respect a difference in heights, between this and the greater height, able to support in post-blow operations (filling and storage), that the central part of the bottom maintain enough rigidity, achieving that the petal contact area is always the one that is actually acting.
