Definitions

  • the object of the present application is the registration of a closing cap for containers.
  • the invention proposes the development of a closing cap for containers with environmental advantages as regards the recycling of containers with a cap, as well as advantages in the manufacturing process thereof.
  • closure caps made from plastic material have been used for many years, which are provided with an internal thread that can be threaded into a thread formed in the neck of the container itself, allowing the contents of the interior of the container to be kept airtight, for example, in the case of a bottle of the type used for bottling beverages, such as mineral water, soft drinks, or the like.
  • the present invention has been developed in order to provide a closure cap that is configured as a novelty within the field of application and solves the aforementioned drawbacks, also providing other additional advantages that will be evident from the description that follows. accompany below.
  • a closure cap for containers in particular intended for containers that have an opening in a neck provided with a threaded outer portion, comprising a lower ring intended to be coupled to the neck of the container and a upper cap having an inner threaded region configured to engage the outer threaded portion of a container neck, the upper cap and the lower ring being articulated to each other by means of a hinged portion, such that the lower ring is formed by a ring-shaped body, characterized in that the lower ring has a section with a diameter greater than the remaining section of the ring-shaped body, wherein the hinged portion is located in the section with the largest diameter.
  • this design facilitates the manufacturing process since it can be carried out by using plastic injection molds devoid of slides, which reduces investment, maintenance and manufacturing costs, since the provision of These two regions with different diameter allow to simplify the design of the hinged portion.
  • closure cap includes a tamper evident seal between the upper cap and the lower ring, which ensures that the container has not been previously manipulated before use by the user.

  • the upper cap (2) and the lower ring (1) are articulated to each other by means of a hinged portion (3), which facilitates the user to manipulate the closure cap and prevents both parts from being separated, since the entire set made of a single piece of injectable plastic material.
  • An outer surface of the side face defined by the body of the upper cap has a non-smooth surface (21), for example, a knurled surface formed by ribs extending from the upper part to the lower part of the body of the upper cap.
  • the lower ring (1) of the closure cap is made up of an annular-shaped body and has a first section (10) with a diameter greater than a second (11) that corresponds to the remaining section of the annular-shaped body, the hinged portion (3) located in the section (10) with the largest diameter.
