Definitions

  • the present invention is a closure with evidence of opening intended to be installed on the mouth of a container, preferably a bottle, in such a way that not only is the container prevented from being fraudulently refilled, but its appearance and external configuration also show when it has been opened at least once.
  • Fraudulent techniques are designed to allow customers to be offered a refilled container with a lower-value liquid, but which appears to be the original. This way, the customer pays for a product that supposedly has a higher value than what they actually receive.
  • a first security mechanism consists of providing a means for this initial opening to alter the appearance of the closure in such a way that the customer realizes that the container with the closure has already been opened and is not in its original, manufactured form. Only by receiving a container with an unopened closure can we be sure that the contents are the original.
  • closures designed to demonstrate the first opening specifically those developed by the applicant himself, where there is a first closure configuration before the first opening and a second closure configuration after the second opening.
  • the success of this solution is that the transition from the first configuration to the second configuration is irreversible.
  • a first aspect of the invention is a closure with first-opening evidence, which is installed on the mouth of a container and in particular on the mouth of a bottle.
  • This closure comprises the following elements: a pourer with external thread, where the pourer comprises at least one peripheral region configured to be visually accessible after the first opening; a cap with internal thread, where the cap is configured to screw onto the external thread of the pourer in an axial direction, and where before the first opening and according to the axial direction, the cap extends through three sectors: i. an upper sector, which comprises the internal thread, configured to allow the cap to be gripped and opened by turning,
  • an intermediate sector comprising a perimeter band extending between a first end and a second end characterized in that the perimeter band is temporarily connected by a first weakening line to the upper sector, is temporarily connected by a second weakening line to the lower sector, comprises a gripping element at the first end to allow the grasping and subsequent tearing by traction of the first line of weakening and the second line of weakening, where the perimeter band is positioned according to the axial direction, at least in part, superimposed on the perimeter region of the spillway and configured to be visually accessible after the first opening.
  • One of the advantages of this first aspect of the invention is the use of only two essential parts: the spout and what will be called a cap, but which, in a single part, includes several elements, which will be distinguished below. Although there are several parts with different functions, as it is a single part, it is manufactured, according to a preferred example, by plastic molding in a single operation, drastically reducing manufacturing costs.
  • the pourer is a part that is hidden by the stopper until the stopper is removed. Originally, the stopper covers the pourer so that it is not visually accessible before the first opening. In a preferred example, the pourer is a part that fits over the neck of the bottle, and it is on the pourer that the stopper remains fixed during the manufacturing process; that is, in a position prior to the first opening.
  • the pourer includes an additional part, a chassis, which serves as an interface with the neck of the bottle.
  • the chassis is preferably made of a material with greater flexibility than the pourer material and serves to establish a seal between the pourer and the mouth of the container.
  • the pourer also includes a single or double valve, to prevent fraudulent refilling of the interior of the container.
  • the pourer comprises a perimeter region configured to be visually accessible after the first opening. That is, before the first opening it is not visually accessible, but after the first opening it is this region that is visually accessible and therefore observable by the user.
  • the user upon seeing this region not accessible before the first opening, has the information that the closure has already been opened at least once, so if they acquire the container with the closure as original, they can reject it because they know that has been manipulated.
  • This perimeter region does not have to extend around the entire perimeter, although it is advisable since the first opening is evident from any observation direction when there is visual access to this region.
  • the stopper is the part that changes configuration between a first state and a second state. The first state before the first opening and the second state after the first opening.
  • the cap has an axial direction, which is the direction in which it moves, regardless of rotation, during screwing and unscrewing operations. It has an internal thread adapted to fit onto an external thread of the pourer. When the cap closes the pourer, a tight seal is established that prevents liquid from escaping from the container.
  • the plug comprises three sectors connected by lines of weakness.
  • a line of weakness is a temporary mechanical bond, continuous or discontinuous, distributed along a path.
  • lines of weakness are channels that reduce the thickness of a wall along a path, allowing it to break along this weakened area under stress.
  • frangible bridges are small links between the parts to be joined, distributed along a path. A stress exceeding the breaking strength separates the two parts previously connected by the frangible bridges.
  • the three sectors of the cap are distributed according to the axial direction, with the lower sector located closest to the container when the closure is installed on said container, the upper sector located furthest from the container, and the intermediate sector, in the form of a perimeter band, located in an intermediate position. also according to the axial direction, between the upper sector and the lower sector.
  • the upper section includes the thread and is therefore the part that allows access to the container to be opened and closed, ensuring a tight seal even after the first opening.
  • the lower section is adapted to be fixed at least axially to the pourer.
  • the fixation also includes a rotational lock. That is, this lower section establishes a permanent connection with the pourer both before and after the first opening. This permanent connection ensures, before the first opening, the entire stopper is secured securely, preventing any tearing or breakage.
  • the intermediate sector is located, according to the axial direction, between the lower sector and the upper sector and is formed by a perimeter band delimited from the other sectors by a line of weakness.
  • connection to the upper sector is via a first weakening line
  • connection to the lower sector is via a second weakening line.
  • both weakening lines extend around the perimeter and are parallel.
  • this perimeter band that forms the intermediate sector is interrupted so that it has a first end and a second end.
  • the first end has a gripping element that allows the user to grasp it and, by pulling on it, cause the first and second lines of weakness to progressively break until the band forming the intermediate sector becomes independent of both the upper and lower sectors.
  • This band, once removed, is now discarded.
  • the upper section serves as a closing cap for the pouring spout, allowing it to be unscrewed to dispense the liquid stored in the container and then screwed back on to reseal.
  • the lower sector remains attached to the bottom of the weir and spaced apart from the first sector.
  • the spillway is connected to the lower section by a section of skirt that is one inside the other, reinforcing the rigidity of the assembly.
  • This section can no longer be covered because the intermediate section has lost the ties that held it in place, covering the perimeter of the spillway, designed to be visually accessible after the first opening. This means that not only is the first opening evident, but it is irreversible.
  • the closure comprises a chassis configured to be partially inserted into the neck of a container in its lower part and to be inserted into the interior of the pourer in its upper part.
  • chassis The presence of a chassis has been described above as an example.
  • This element is mechanically inserted between the spout and the neck of the container, preferably the container's mouth, and allows the spout's tightness to be established when the closure is operationally installed on the container's mouth.
  • the chassis material is more flexible or at least elastically deformable under an external force, allowing it to hug the spout and also a wall of the neck or, more particularly, the mouth of the container to ensure a tight seal.
  • the upper sector comprises a cylindrical section adapted to establish a seal with the interior of the spillway.
  • the pourer comprises a pouring surface through which the liquid stored in the container is poured.
  • the screwing motion in addition to rotation, is axial and moves (descending according to the convention described at the beginning) in the direction of the container to establish a seal.
  • the seal is established, according to this embodiment, through a cylindrical section that exerts pressure against the internal walls of the pourer, preferably on or near the pouring surface.
  • the upper sector comprises a cavity in its outer surface configured to at least partially house the gripping element.
  • the gripping element is located at the first end of the intermediate sector. Since in the preferred examples the intermediate sector establishes continuity at least on the outer surface between the upper and lower sectors, the presence of a cavity housing this gripping element ensures that the gripping element also maintains the continuity of the outer surface. Surface continuity is defined as not appearing noticeably raised from the rest of the surface.
  • it may have reliefs, which are indentations and protrusions, for example to ensure the user's grip, but these indentations and protrusions do not stand out noticeably since they affect the texture of the surface and are not as thick as the gripping element.
  • the cavity comprises an area that after the removal of the intermediate sector passes from being at least partially covered by the gripping element to being visually accessible. This additional area also helps demonstrate a change in appearance, where, for example, it's possible to add other visual elements that emphasize that the closure has been opened for the first time.
  • the upper sector comprises two separate, essentially cylindrical sections: an inner cylindrical section and an outer cylindrical section, the inner thread located on the inner surface of the inner cylindrical section and the outer cylindrical section being configured to allow the cap to be gripped and opened by turning.
  • essentially cylindrical should be interpreted as meaning that the element or part thus characterized is formed by a body of revolution whose shape is generated by the rotation of a directing line.
  • the preferred example of this characteristic is a body of revolution formed by the rotation of a straight line.
  • a cylinder or a cone are figures covered by this interpretation.
  • cylindrical sections are formed by cylinders where the directing line is a straight line parallel to the axis of rotation, the axial axis, or with a slight inclination that results in a small taper, for example, to facilitate extraction from injection molds when the part is made of molded plastic.
  • any pressure exerted by external forces against the outer cylindrical section will cause some deformation that is not transmitted to the inner cylindrical section or is highly damped, preventing these deformations. may compromise the coupling established by the thread.
  • the user has access to the outer cylindrical section, while the cap thread is located on the inner surface of the inner cylindrical section.
  • This configuration protects the thread, making it even more inaccessible. Any attempt to insert a tamper-evident element will tend to lodge between the two sections, the inner cylindrical section and the outer cylindrical section, preventing access to the thread.
  • this distance between the inner cylindrical section and the outer cylindrical section that also generates the cavity in which the gripping element is housed.
  • the dimension in a radial direction of these stops determines to what extent it will be transmitted to a user that the outer cylindrical section deforms inwards when the cap is manipulated to open or close the container, while preserving at the same time to the inner cylindrical section from deforming in the event that it were to deform the outer cylindrical section outwards.
  • the pourer is an internal part of the cap and establishes the connection between the cap and the neck of the bottle.
  • the pourer includes securing means that rest on them.
  • These axial and anti-rotation securing means are preferably configured to establish insertion securing, making this insertion irreversible. They preferably include guiding means during insertion that guide the orientation and final position of the pourer so that they anchor properly in cooperation with the means provided by the neck of the bottle. This securing is established when the closure is installed on the bottle in operational mode, preferably with a insertion installation.
  • said chassis comprises a non-return valve.
  • the pourer comprises a perimeter flange that rests on the inside of the plug in a position below the second line of weakness and proximal to it.
  • axial retention between the pourer and the cap is established at this location.
  • Other locations where support is established are points on a lower skirt of the pourer and on the upper part, where the seal is established.
  • the pouring surface ends in a pouring rim that rests on equally distributed internal projections on the cap, ensuring that there is no excessive pressure on other parts that ensure the seal.
  • the intermediate sector is distanced from at least the perimeter region of the landfill.
  • This distancing means that, after the initial opening, when the intermediate section has been removed, it cannot establish not only a temporary or fixed connection with the closure elements, but it also cannot support them. If it had a support, it would be possible to reposition the intermediate section to fraudulently attempt to show its original appearance.
  • the distancing eliminates any support or positional reference for this purpose.
  • a second aspect of the invention is a container comprising a bottle neck closed by a closure according to any of the preceding claims.

  • FIG. 1 a first exemplary embodiment of the first aspect of the invention is described where the closure is shown in perspective from an elevated viewpoint and a lower viewpoint.
  • the terms “upper” and “lower” will be used. These terms should be interpreted as meaning that the lower part is where the container is located and the upper part is where the closure is located, depending on the direction established by the action of gravity when the closed container is in operation and resting on a horizontal surface. In this way, the axial direction of the neck of the container and the closure installed on said neck of the container are oriented vertically. However, in containers that can be designed obliquely, the axial direction of the neck of the container and the closure will be established by the relative terms “upper,” “lower,” or other equivalent and similar terms.

  • the visible part is the cap (2) which is formed by three sectors, an upper sector (2.1) which in this embodiment shows a fine groove on its outer surface.
  • the fine groove increases the grip capacity of the user when screwing and unscrewing this upper sector (2.1) on a pourer (1) which is not visible in these figures and which will be described later.
  • This upper sector (2.1) is the one that establishes the hermetic closure not only before the first opening but also in subsequent closures with the use of the container and closure.
  • this sector is mainly formed by a perimeter band (2.2.1) that surrounds the closure and that has two ends (2.2.1a, 2.2.1b), a first end (2.2.1a) and a second end (2.2.1b) opposite the first end (2.2.1a).
  • the ends (2.2.1a, 2.2.1b) are not mechanically connected.
  • At the first end (2.2.1a) there is an extension that increases its area upwards, configuring a grip element (2.2.2).

  • Figure 9 shows the closure configuration when the upper section (2.3) has been rethreaded. It can be seen how both the cavity (2.1.3) and the perimeter region (1.2) are now uncovered, modifying the external appearance. According to an example applicable to any of the examples described, these parts, now visually accessible, are in a different color. According to a specific way of achieving this color, it is through the color of the internal parts visible through a pourer (1) made of a transparent material.
