Abstract

The present invention relates to a handle for containers, more precisely for carboys containing liquids, manufactured from the same material as the container, specifically polyethylene terephthalate (PET), and which is coupled to the neck of the container. Traditionally, carboy handles are made of high-density polyethylene (HDPE) due to its strength, but this makes recycling difficult, as there are components of different materials that must be separated beforehand. The present invention solves a set of problems that had not been solved before, allowing the manufacture of PET handles, promoting greater recyclability and addressing environmental concerns. The handle consists of a grip (A.1) and a rim (A.2) to which the grip (A.1) is attached and which is inserted into the neck of the container. At least one tab (A.2.1) is coupled to the rim (A.2) for attachment to the neck of the container.

[0001] DESCRIPTION

[0002] Ergonomic handle for container

[0003] Technical mastery of the invention

[0004] The present invention relates to a handle for containers, more specifically for containers for liquids, even more precisely for bottles containing liquids, and which is manufactured from the same material as the container. The handle of the present invention is intended to be part of a container as a complementary element attachable to the neck of the container, emerging laterally and horizontally from a ring attachable to the neck of the container and allowing subsequent upward tilting during the lifting of the container suspended by the handle of the handle.

[0005] Framework of the invention

[0006] In the marketing of different types of products, generally liquids, such as beverages, water, oils, olive oils, among others, containers in the form of a large-capacity bottle are used, namely 5 or 6 liters, or others, commonly known as demijohns, which are equipped with a handle, which integrates a device commonly known as a wing, to facilitate their transport and lifting. This wing is not integrated into the container, being manufactured separately and then fitted onto the neck of the demijohn.

[0007] Generally, these containers are manufactured from polyethylene terephthalate (PET), but due to the difficulty in manufacturing resistant products in this material, high-density polyethylene (HDPE) is generally used in the manufacture of the handles, as handles made from this material have much greater resistance than those made from PET. However, at a time when recycling is highlighted and it is necessary to increase the percentage of reusable or recyclable products, especially products whose natural degradation is particularly slow, as is the case with plastics, the fact that a product contains two different components that must be separated beforehand causes a problem for its recycling.

[0008] It is important to highlight that, currently, due to the variety of raw materials used in wing production, as well as the enormous variety of colors that can be applied, there are many limitations in the post-consumer recycling process, which prevents the reintegration of these materials into the production of new wings.

[0009] With the possibility of producing wings from PET, it is possible to produce these same wings using exclusively recycled raw materials or with a high rate of incorporation of recycled material, since the market already provides this raw material, predominantly for the production of packaging.

[0010] In order to solve this problem, the need arose to fill this existing gap in the market and manufacture a wing, not integrated into the container, in PET.

[0011] However, given the characteristics of PET, manufacturing a wing from PET presents a set of problems that need to be solved in order for a wing made of PET, not integrated into the container, to become a reality.

[0012] Among the problems whose resolution was necessary, the following stand out:

[0013] 1) Difficulty in fitting the wing into the neck of the container due to the lack of flexibility of the petals and the mismatched diameter of the rim, compared to existing products, which are produced with high-density polyethylene (HDPE);

[0014] 2) Difficulty in the rotating movement of the wing handle when supporting the load (container weight);

[0015] 3) Difficulty in the molding process, in terms of filling the parts, due to the different fluidity of the PET polymer compared to the HDPE polymer;

[0016] 4) Difficulty in preventing degradation of the PET polymer in the injection molding system, with possible impact on the final product (loss of functional characteristics, such as rupture and loss of load-bearing capacity).

[0017] 5) Difficulty in the demolding process, due to the PET polymer adhering more to the mold, which makes it difficult to extract the parts.

[0018] Background of the invention

[0019] Several patent documents were found that present solutions for handles for containers placed on liquid bottles, but whose objective is not the manufacture of handles in the same material as the container.

[0020] Note in particular the document ES1058549U which presents a

[0021] "Water bottle handle" whose main characteristic is having elements that facilitate the removal of the handle.

[0022] Or document EP1459994A1, which also refers to a "Wing for a water bottle," but whose purpose is to ensure that all components remain coplanar.

[0023] There are also documents that present handles made of the same material as the container, more specifically PET, but these handles are integrated into the container itself. An example of this type of handle can be found in document US2005 / 0048237.

[0024] Advantages of the invention

[0025] The main advantage of the invention's equipment is that it provides a wing made of PET with the same functional characteristics of hardness, durability, flexibility, and stability as wings made of HDPE.

[0026] This type of handle, made from the same material as the container, namely bottles, facilitates recycling by avoiding the need to separate the bottle from the handle for recycling, which happens with current bottles, since the recycling of PET bottles and HDPE handles is carried out separately.

[0027] Additionally, the wing of the invention offers greater ergonomics, due to its construction, when compared to existing wings.

[0028] One of the major differences between the wing of the invention and the wings of the prior art is that the wing of the invention, in relation to existing wings, has a different outer and inner diameter at the lower end of the rim, and the width of the rim varies along its entire length, resulting in slopes along its entire length. These two combined features, contrary to what one might expect, make the wing more ergonomic and the operation of placing the wings on the containers easier.

[0029] Brief description of the figures

[0030] These and other characteristics can be easily understood through the attached drawings, which should be considered as mere examples and in no way restrictive of the scope of the invention. In drawings, and for illustrative purposes, the measurements of some of the components may be exaggerated and not drawn to scale. The absolute dimensions and the relative dimensions do not correspond to the actual relationships for carrying out the invention.
