Definitions

  • the object of the present application is to provide 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.
  • closing caps made from plastic material have been used for many years, which are provided with an inner thread able to be threaded in a cut formed in the neck of the container itself, enabling the contents inside 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 with the aim of providing a closing cap which is configured as a novelty within the field of application and solves the previously mentioned drawbacks, further contributing other additional advantages which will be obvious from the description below.
  • An object of the present invention is therefore to provide a closing cap for containers, particularly intended for containers that have an opening in a neck provided with an outer threaded portion, comprising a lower ring intended for being coupled to the neck of the container and an upper cap having an inner threaded region configured for being coupled to 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 an annular-shaped body, characterised in that the lower ring has a section with a diameter larger than the remaining section of the annular-shaped body, wherein the hinged portion is located in the section with the larger diameter.
  • this design facilitates the manufacturing process since it can be carried out by using plastic injection moulds devoid of slides, which reduces investment, maintenance and manufacturing costs, since the arrangement of these two regions with different diameters enables the design of the hinged portion to be simplified.
  • the closing cap includes a tamperproof seal located between the upper cap and the lower ring, which ensures that the container has not been previously manipulated before use thereof by the user.
  • the tamperproof seal is made up of a plurality of breaking points located on a rim of the lower ring that protrudes outwards and attached to a lower edge of the upper cap.
  • the rim of the lower ring that protrudes outwards is located in the smaller diameter section thereof.
  • the hinged portion is formed by an extension of a substantially rectangular shape that at the upper end thereof is attached to the upper cap and at the lower end thereof is attached to the lower ring, such extension being devoid of fold lines.
  • the closing cap described represents an innovative structure with structural and constituent features heretofore unknown for its intended purpose, reasons which, taken together with its usefulness, provide it with sufficient grounds for obtaining the requested exclusivity privilege.
  • FIG. 1 is a perspective view of the closing cap according to the invention, mounted on a container, in a closed condition;
  • FIG. 2 is a perspective view of the closing cap of the invention, mounted on a container, in a raised position prior to the open condition thereof;
  • FIG. 3 is a side elevation view of the upper cap shown in the preceding figures in the raised position
  • FIG. 4 is a side elevation view of the upper cap in a partially open condition
  • FIG. 5 is a side elevation view of the upper cap in a completely open condition
  • FIG. 6 is a schematic view of the closing cap of the invention in a partially open condition from another point of view:
  • FIG. 7 is a perspective view of a second embodiment of a closing cap according to the present invention, mounted on a container neck, in an open condition;
  • FIG. 8 is a lower perspective detailed view of the cap represented in FIG. 7 in a closed condition.
  • the closing cap for containers is particularly intended for containers that have an opening in a neck ( 100 ) provided with an outer threaded portion ( 101 ), comprising a lower ring ( 1 ) intended for being coupled to the neck ( 100 ) of the container and an upper cap ( 2 ) having an inner threaded region ( 20 ) (see FIG. 6 ) configured for being coupled to the outer threaded portion ( 101 ) of the container neck.
  • the upper cap ( 2 ) and the lower ring ( 1 ) are articulated to each other by means of a hinged portion ( 3 ), which makes it easier for the user to manipulate the closing cap and prevents both portions from being separated, as the entire set is made of a single piece of injectable plastic material.
  • An outer surface of the lateral 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 portion to the lower portion of the body of the upper cap.
  • the lower ring ( 1 ) of the closing cap is made up of an annular-shaped body and has a first section ( 10 ) with a diameter larger than a second one ( 11 ) that corresponds to the remaining section of the annular-shaped body, the hinged portion ( 3 ) being located in the section ( 10 ) with the larger diameter.
  • both sections ( 10 ) and ( 11 ) are attached by two curved sections ( 12 ) arranged diametrically opposed to each other.
  • the section with the smaller diameter has a diameter such that it is located in a region ( 104 ) defined by two circumferential rims ( 102 , 103 ) provided in the lower portion of the neck of the container, so that during the operation in which the upper cap rises to separate the upper cap ( 2 ) from the upper opening of the container, the ring remains in this region at all times.
  • these two sections with different diameters enable a controlled stretching and subsequent return to the initial position thereof, which enables, once the upper cap has been unscrewed, the lower ring ( 1 ) to be comfortably stretched, holding from the upper cap ( 2 ), to house a portion of the section with the larger diameter ( 10 ) and the hinged portion ( 3 ) below the lowermost circumferential rim ( 103 ) of the container, as shown in FIG. 5 .
  • the upper cap ( 2 ) is perfectly locked, as the inner face of the hinged portion ( 3 ) abuts the lower portion of the circumferential rim ( 103 ).
  • hinged portion ( 3 ) is formed by an extension of a substantially rectangular shape that at the upper end thereof is attached to the upper cap ( 2 ) and at the lower end thereof is attached to the lower ring ( 1 ), such extension being devoid of fold lines, unlike other closing cap systems known in the current state of the art.
  • the closing cap is provided with a tamperproof seal located between the upper cap ( 2 ) and the lower ring ( 1 ).
  • this tamperproof seal is made up of a plurality of breaking points ( 4 ) located on a rim ( 5 ) of the lower ring ( 1 ) that protrudes outwards and attached to a lower edge of the upper cap ( 2 ).
  • the rim ( 5 ) that protrudes outwards is located only in the smaller diameter section ( 11 ).
  • FIGS. 7 and 8 show a second preferred embodiment of the closing cap, wherein the same portions or parts are indicated with the same numerical references as in the example described above.
  • the upper cap ( 2 ) advantageously includes an abutment means configured for being in contact with the circumferential rim ( 103 ) of the neck ( 100 ) in the open position of the upper cap with respect to the lower ring, so that it is ensured that the upper cap ( 2 ), when it is in the open position, does not rotate in an undesired way by effect of the hinged portion ( 3 ) to return to the rest position thereof, that is, when the upper cap ( 2 ) is on top of the lower ring ( 1 ).
  • the abutment means consists of a flange ( 22 ) that extends outwardly from the inside of the body that makes up the upper cap ( 2 ) and parallel to the hinged portion ( 3 ).
  • said flange ( 22 ) takes a position practically or completely parallel to a longitudinal axis of the neck itself ( 100 ) and the hinged portion ( 3 ) is housed below the circumferential rim ( 103 ).
  • the smaller diameter section ( 11 ) of the lower ring includes a circumferential projection ( 13 ) that protrudes outwards.
