Abstract

BOTTLE IN COUPLED POLYETHYLENE TEREFTALATE. Utility Model Patent for a final liquid conveying bottle having a quick-fit coupling neck and bottom (2) located just below its sealing cap (1) which is threaded into the bottom (3) of Another bottle. Both the top and bottom of the bottle have curved shape of same size and shape. The upper (neck) is conical while the bottom is convex. At the position corresponding to the neck thread the bottom has another, in which the neck is fixed. In its initial part of its neck there is a ring with projections (4) which fit in identical ring located in the bottom that has corresponding recesses (5).

Description

"COUPLING TEREPHALIZED POLYETLENE BOTTLE"

The present utility model patent has as its object a model of terephthalated pofretrene bottle for use in beverages, edibles and other fluids currently used in such packaging.

This patent aims to modify the shape of the bottles so that transportation, storage, storage and handling are optimized from the manufacture of the product to its recycling.

Due to their great ease of molding, strength and density, which even allow the packaging of carbonated drinks, we find in the market several formats for terephthalated polyethylene bottles. They are thus widely used for the above reasons and also because they are cheaper and lighter to carry as glass bottle replacements. Another aspect is that this is a recyclable material and with such bottles there is no need to return the container.

Today's bottles, in various shapes, colors and sizes, are designed by their designers to serve primarily aesthetic and marketing purposes. Often taking inspiration from the shape of the previously used glass. With the exception of the modification that reduced, in some models, the diameter to half height, to facilitate the handling and elimination of a plastic base that was quoted at the bottom of the bottles at the time of its launch so that they were standing and replaced. Due to a new background design that guarantees its balance and resistance, there was no innovation of the functional characteristics of the packaging.

Despite the widespread use of bottles in the preservation of various types of beverages, especially the 2 (two) liter packaging, their packaging in refrigerators or freezers, especially the horizontal ones used in various points of sale, is not convenient, as well as the handling of such bottles at the time of consumption, because their plastic structure does not allow, when full, to handle them easily with one hand. For storage in the final consumer home we also find that they occupy a considerable space (some being about 40 cm high).

Another disadvantage is that the end consumer is compelled to drink the entire content of carbonated drinks in a short time, otherwise the gas contained in the liquid will escape into the remaining bottle air, considerably impairing the taste of the drink, and taking up unnecessary space in its refrigerator.

Although bottles are recyclable, the storage of empty containers is also not facilitated as a large amount generates considerable volume occupying storage areas in a totally disorganized manner.

In order to offer a solution to the above described problems, as well as to innovate, improve the presentation and transport of packaging made of terephthalized polyethylene, the present patent proposes a new bottle format, which consists in modifying its neck region and its base, so that each bottle can be fitted into another.

Product size may vary, however the final consumer will have the option of bringing smaller individual amounts of different flavors that will consume to their needs.

Transport and storage will be facilitated as multiple units can be arranged vertically or horizontally to maximize use of the stockpile.

After drinking the beverage, for the same reasons above, it will be easier to store the material to be recycled and with the advantage that when empty the handling and coupling of the bottles will be even easier. Stacks can then be made in quantities that will form sets of tubes that will be transported or stored at one time.

The sketch presented in figure 1 makes the proposal clearer, emphasizing that the main modifications are from the neck and the base, allowing the conception of different wall shapes. In the drawing we elaborate a representation of the present proposal. In its upper region we have the neck and in the lower one we represent by dashed lines the bottom. We emphasize that the final dimensions will be established by the manufacturer of the liquid to be filled.

We detail the following:

The proposed innovation is to model a double-threaded thread (2) just below the cap (1), which seals the contents of the container, causing the bottle to be screwed to the bottom (3) of another. This bottom will also have a new design, which is essentially a "negative" of the top of the bottle.

The upper tapered part of the bottle starts from a ring that has two diametrically opposed shoulders (4) that will also fit into the two bottom recesses (5) of another bottle making the threaded oggle have a limit and provide the user with a tactile end feel. coupling.

It is clear that the bottom of the bottles will allow the same (or better) balance as the current bottles on the market. Every lower ring will be in contact with the bearing surface except for the two recesses. The neck of the neck will have the function of the existing ring existing under the lid on today's bottles, that is, to facilitate the transport and will also be the element of union of the packages. For this, we opted for a fast thread two threads. A thread was chosen, as a simple snap fit would not give a safe transport, since each bottle can come despite more than two pounds, which could cause the disengagement simply by their weight. Two wires, so that the coupling operation will be quick, taking only half a turn.

Claims (4)

1.) "ADJUSTABLE POLYETHYLENE TEREPHALATE BOTTLE", understood as a bottle for packaged liquids in molded plastic containers of polyethylene terephthalate, closed with a screw cap (1) and used in carbonated or non-carbonated beverages, characterized in that their neck has a thread ( 2), which will be threaded into the bottom (3) of another bottle of the same size, thus forming a unique assembly which may be increased by coupling more units. The thread (2) is a fast two-threaded type so that the fitting is the fastest and safest possible. The bottom (3) has the neck design but convexly, that is, so that the entire upper part is coupled therein. In the initial region of the neck, there is a ring in which there are shoulders (4) for the secondary fit with the recesses ( 5) in the ring of the same size, located at the base of the bottle. The dimensions of the walls of the container are whatever suits the manufacturer.
