Definitions

  • the present invention belongs to the field of closure elements for containers, and more specifically caps for containers with a leaktight closure.
  • An object of the invention is to therefore provide a cap for containers capable of assuring the sealing of the content.
  • Another object of the invention is also to provide a cap for containers capable of improving tightness with the neck of the container, such that the resistance to pressures or damage sustained during transport is improved.
  • Another object of the invention is also to provide a cap for containers capable of improving stability against the risk of sliding and seal loss during palletization, storage or horizontal transport operations.
  • caps for containers those caps with a contact surface provided for being coupled to the neck of a container and preserving its content are known.
  • caps of this type use a type of irregularity on their inner perimetral face to contact the outer side of the neck of the container, which allows a certain sealing to be achieved when a user couples the cap to the container.
  • caps of this type have a series of drawbacks. These notably include, among others, the fact that these caps often close the container through the outer side of the neck thereof and the presence of small burrs causes the sealing to be inadequate. Likewise, even starting from an initial leaktight situation, due to the configuration thereof, it is common for storage or transport operations to cause a critical sealing deformation, even giving rise to leakages.
  • the cap for containers proposed by the present invention is therefore presented as an improvement over what is known in the state of the art, given that it satisfactorily achieves the objectives indicated above as ideal for the art.
  • the invention consists of a cap for containers comprising a cylindrical body comprising, on the inner face thereof, a cylindrical skirt and a rib, where the cylindrical skirt and the rib are sized for contacting the inner face of the neck of the container and creating at least two sealing areas. Therefore, the invention advantageously provides closure means for closing the opening of the neck for improving the sealing of the container.
  • the rib has a cylindrical shape providing a continuous perimetral relief on the inner face of the upper base of the cylindrical body.
  • the rib has an outer perimeter larger than the outer perimeter of the cylindrical skirt.
  • the width of the cylindrical skirt, according to the axial axis of the cap is greater than that of the rib.
  • the cylindrical skirt comprises a protuberance on the lower edge of its outer face for contacting the neck of the container. Therefore, the contact of the cylindrical skirt with the inner face of the neck of the container is advantageously made easier, which assures the sealing of the container.
  • the inner face of the upper base of the cap comprises a first and second attachment point, from which the cylindrical skirt and the rib project, respectively. Therefore, advantageously, the sealing areas are completely independent and offer better resistance against sealing loss due to manufacturing defects, blows received during storage, warehousing or transport.
  • the rib is arranged on the outer face of the cylindrical skirt. Therefore, a second point of contact of the cylindrical skirt with the neck of the container is advantageously assured, which assures a second sealing area.
  • the cylindrical body is formed by the articulated attachment of two superimposed parts, a lower part and an upper part.
  • the double-sealing solution of the present invention described above is advantageously arranged in the upper part of the cap, so, in addition to the caps described above which are formed by a single rigid body, the present invention is also adapted to caps of this type having two bodies which are widely used, for example, in oil bottles or small water bottles.
  • the lower portion to be provided with gripping means for the retention thereof on the neck of the container and the upper portion to be provided with the cylindrical skirt and the rib.
  • this configuration keeps the cap, specifically its lower portion, coupled to the neck of the container at all times, so the loss thereof is prevented and there is only a need for a simple movement of the upper portion of the cap which fits into the neck by pivoting about the hinge-type articulated attachment, the container being closed and sealed.
  • the present invention contains a series of technical features involving advantageous technical effects which mainly include, among others, improvement of the sealing that is provided. Therefore, the present invention prevents dust and/or foreign bodies from entering the container, preventing them from coming into contact with the content thereof.
  • the double-sealing solution of the present invention is applicable to all types of caps, such as for example caps having a single body, caps having two parts attached to one another by means of a hinge or any other variation.
  • the two sealing areas provided by the cap reduce the weight of the cap and use a clean surface of the neck of the container for contact. Furthermore, the risk of receiving blows is lower in the inner area than in the outer area of the neck, which allows better withstanding any pressure or damage sustained during transport or palletization.
  • the two inner circular contacts that are provided assure good vertical stability of the cap when it is placed on the neck of a bottle and excellent stability against any risk of sliding and seal loss in warehousing or horizontal transport operations.
  • the present invention discloses a double-sealing solution for container caps which is based on a cap inner face configuration comprising a cylindrical skirt 5 and a rib 7, where the cylindrical skirt and the rib are sized for contacting the inner face of the neck (2) of a container and thereby creating two sealing areas.
  • Figure 1 shows a cap 1 provided on the neck2 of a container in an open position.
  • the cap 1 is formed by the articulated attachment of two superimposed parts, a lower part 3 and an upper part 4.
  • the lower part 3 comprises gripping means for the retention thereof on the neck2 of the container, both while opening and closing the cap 1.
  • Figure 2 shows a front view of the cap 1 in a closed position.
  • said cap 1 consists of a substantially cylindrical body formed by the articulated attachment of the lower part 3 and the upper part 4.
  • Figure 3 shows the inner portion of the cap from a rear view.
  • the upper part comprises a cylindrical skirt 5 projecting from the inner face of said upper part and a cylindrical rib arranged continuously on the inner face of the upper part.
  • Both the cylindrical skirt and the rib are sized for the insertion thereof into the neck2 of the container, such that they contact the inner face of the neck at at least two points of contact located at different heights.
  • the points of contact are substantially circular and concentric points of contact, providing continuous contact with the inside of the neck of the container along the entire perimeter thereof. Good vertical stability of the cap when it is coupled to the neck of the container is thereby assured.
  • the cylindrical skirt preferably has a protuberance 6 arranged continuously on the lower edge of its outer face for contacting the neck of the container.
  • the cylindrical skirt 5 and the cylindrical rib 7 each have a permanent attachment with the upper part at two different points of the inner face thereof, specifically following two concentric circumferences with a different diameter.
  • the cylindrical rib in an alternative embodiment with respect to the preceding paragraph, it is contemplated for the cylindrical rib to be arranged on the outer face of the cylindrical skirt itself. In this sense, there is only a single attachment point with the inner face of the upper part, i.e., the one defined by the cylindrical skirt 5 itself and the inner face of the upper part. In this configuration, the cylindrical rib projects from the upper edge of the cylindrical skirt 5, on the outer face thereof, to contact the neck of the container at a point close to the neck.
  • Figure 4 shows a cross-section of the cap 1.
  • the two points of contact 8 and 9 between the cylindrical skirt 5, the cylindrical rib 7 and the inner face of the neck of the container, respectively, define two sealing areas. Therefore, the sealing areas advantageously use a clean surface of the neck of the container, or at least one that is cleaner than the outer surface, which also reduces the risk of receiving blows with respect to configurations using the outer face of the neck of the container and reduces the weight of the cap.
  • the diameter of the outer perimeter of the protuberance 6 is smaller than the outer perimeter of the cylindrical rib 7.
  • the width of the skirt 7, measured according to the axial axis of the cap is greater than that of the cylindrical rib 7. Therefore, the protuberance of the cylindrical skirt is sized for being introduced a certain distance into the container and to contact a first point of contact 8 assuring a first sealing area, whereas the rib is sized to contact a second point of contact 9 inside the container, closer to the end or mouth of the container than the first point of contact, assuring a second sealing area.
  • the sealing areas thus defined inside the container withstand any pressure or possible damage sustained during transport better than the solutions using the outside of the container do. Likewise, it offers excellent stability against the risk of sliding and assures that there is no seal loss during palletization, storage or horizontal transport operations.
  • the double sealing of the product is achieved every time the cap is closed, i.e., when the upper part 3 is introduced in the mouth of the container using the articulated attachment which attaches the upper part 3 with the lower part 2.
  • This articulated attachment comprises two pairs of vertical notches 10, arranged in a manner parallel to the axial axis of the cap 1, defining two strips 11 for attachment between both lower and upper parts. Said strips 11 form the articulation of the lower part and the upper part.
  • the described configuration provides an improved sealing as it has at least two sealing areas preserving the interior of the container. Additionally, closure can be improved by combining the cylindrical skirt 5 and the cylindrical rib 7, arranged to contact the inner portion of the container, with similar elements arranged to contact the outer portion of the container. Therefore, one or more perimetral reliefs 12 can be included on the inner face of the lower part 3 which reduce the inner area of the cap 1 and contribute to preventing dust from entering the container. Additionally, the upper part 4 can also include one or more burrs on the lower edge of the perimetral wall 13 thereof, such that it faces the cylindrical skirt and can contact the outer face of the neck 2 of the container, limiting the entry of dust and/or foreign bodies into the areas of contact with the mouth of the consumer.
  • Figure 5 shows a cross-section of a cap 20 according to a particular embodiment of the invention.
  • the inner configuration is the same as the one described above for the cap having two articulated parts. The difference lies in the fact that the cap of this embodiment depicted in Figure 5 is formed by a single rigid body.
  • the cap 20 therefore has a cylindrical skirt 5 projecting from the inner face of the cap (specifically from its upper base) and a cylindrical rib 7 arranged continuously on said inner face. Both the cylindrical skirt and the rib are sized for the insertion thereof into the neck 2 of the container, such that they contact the inner face of the neck at at least two points of contact 8, 9 located at different heights.
  • the points of contact are substantially circular and concentric points of contact, each of them providing continuous contact with the inside of the neck of the container along the entire perimeter thereof. Good vertical stability of the cap when it is coupled to the neck of the container is thereby assured.
  • the cylindrical skirt preferably has a protuberance 6 arranged continuously on the lower edge of its outer face for contacting the neck of the container.
  • the cylindrical rib in an alternative embodiment, it is contemplated for the cylindrical rib to be arranged on the outer face of the cylindrical skirt itself. In this sense, there is only a single attachment point with the inner face of the upper part, i.e., the one defined by the cylindrical skirt 5 itself and said inner face. In this configuration, the cylindrical rib projects from the upper edge of the cylindrical skirt 5, on the outer face thereof, to contact the neck of the container at a point close to the mouth of the container.
  • the cap 20 can include one or more perimetral reliefs 12 and/or one or more burrs on the inner face of the perimetral wall 21 which reduce the inner area of the cap 20 and contribute to preventing dust from entering the container.
