Definitions

  • the present invention relates to a locking means for a cap designed to be particularly resistant to impact forces to provide for a leak-tight fitting whilst allowing simple and quick release.
  • a preferred field of use is that of caps for large containers for domestic or household use, containing detergents or other cleaning preparations, fabric conditioners and the like.
  • said cap may equally be suitable in other fields of use such as containers for manual and automatic dishwashing liquids, hair-care products and oral care applications such as mouth washes.
  • container caps suitable for use with containers holding fluid base substances such as, shower gels, hair shampoos, suncreams, sun lotions, body oils and the like.
  • the purpose of these caps is, on the one hand, to form a leakproof seal so that the substance contained within does not escape and so that outside air does not constantly pervade the container.
  • such cap should be easy to open and close.
  • Caps of this kind usually have an essentially tubular-shaped cap body with a female thread provided in its inner wall for screwing onto, for example, an accordingly configured (male) thread at the upper end of a container neck.
  • a sealing arrangement By means of a sealing arrangement, a leakproof connection is created between the cap and the container.
  • US6409034B relates to a hinged cap body designed for fitting with a leakproof seal on a container opening, a hinged lid joined to the cap body for closing an outlet aperture formed on the cap body, and a locking arrangement formed on the cap body and the hinged lid. Sealing is achieved via a protrusion extending from said hinged lid which at least partly lodges in the outlet aperture when the lid is closed.
  • Ease of opening and closing is achieved via a combination of; an elastically deformable material, which creates a biasing force between the cap body and the hinged lid in order to bring the hinged lid into an open position; and a locking projection which, in closed position, clutches rearwards to a biased, manually operable locking element which is disposed on the cap body.
  • the locking arrangement is especially simple to use in that only a light pressure must be manually applied to disengage the locking element from the locking projection and allow the elastically deformable material to flip the hinged lid open.
  • Such device introduces a number of disadvantages.
  • One disadvantage is that the hinged lid may easily flip open if the container is accidentally knocked over by the user and cause spillage of the content.
  • Another disadvantage is that the only sealing means for preventing the content to exit the outlet aperture is the protrusion on the hinged lid which may leak when subjected to high pressures caused by, for example, high impact forces during transportation.
  • Further disadvantages may be: alignment problems between the protrusion and the outlet aperture in case of distortion of the hinges and/or its suitability only for small outlets.
  • Caps provide various locking mechanisms, particularly for child-proof containers of medications. Caps of this kind use mechanisms such as the "push-and-turn" system or other mechanisms such as those described in WO2006/102601A1 and US7404495B2, which require the combination of a radial force and an upward force applied onto a portion of said locking mechanism to open said cap. Although these mechanisms may be useful in preventing a child from opening the caps, they render singlehanded operation difficult, which may be important for certain users, such as for elderly.
  • EP2218654A1 relates to a cap comprising a base portion with an outer periphery adapted to extend over at least a portion of a container, a skirt depending downwardly from the base portion and a lip seal member depending downwardly from the base portion.
  • the container has an opening bounded by a lip extending upwards from the container.
  • the lip seal member is adapted to abut an interior side of the lip, when the cap is in closed position.
  • Such devices although suitable for preventing moisture entering or exiting the container, do not provide a strong enough locking force to prevent the lid from opening upon impact. Furthermore, such devices rely solely on a single sealing surface thus more likely to leak during, for example; handling of the container by the user wherein the container is subjected to a given, albeit small, holding pressure; or accidental knock-over.
  • the present invention relates to a locking means for a cap capable of connecting to a container, said locking means comprising a panel connected to a lid of said cap on at least a portion of the perimeter thereof. At least one protrusion extending from a portion of said panel towards the inside of said lid for coupling with a slot provided in a portion of a cap body of said cap and further, an elastically deformable material connecting said panel to said lid, wherein at least a portion of said protrusion (26) extends at an angle c and wherein at least a portion of said slot (27) is slanted at an angle b so that coupling with said protrusion (26) is achieved when said lid (3) is pressed onto said cap body (2), and wherein the angle c of said protrusion (26) is between 1 and 2 degrees and the angle b of said slot (27) is between 0 and 2 degrees, taken from a plane perpendicular to the longitudinal axis (YY).

  • the distance between the uppermost portion of the top (12) of the spout (6) and the apex of said outer wall (7) may be at least 6 mm preferably at least 7mm, more preferably between 7 and 10 mm. It is understood that said distance between the uppermost portion of the top (12) of the spout and the apex of said outer wall (7), and thus the total height of the spout (6), may also be determined by the height of said lid (3).
  • This embodiment is particularly advantageous for allowing pouring of a liquid content to be achieved in a predetermined direction without dripping onto the outer wall (7) and/or container.
  • the cap body (2) may further comprise a female thread (14) extending from said inner surface (9) for coupling with a container neck threaded accordingly, to secure said cap body (2) onto said container.

  • the distance "a" between the apex of said bridge-type portion (15) and said flat surface (17) is between 2mm and 3mm, preferably between 2.2mm and 2.5mm. This specific notch configuration and range of thickness has been found to be particularly beneficial to reduce the stress concentrations generated upon tightening of the cap body (2) onto the container neck and to contribute in stiffening the bridge-type portion region against deflection at high torque.
  • said cap body (2) may comprise a plug seal (18) proximal said flat notch (16) extending substantially parallel to the longitudinal axis (YY) of said cap body (2).
  • the plug seal (18) may be capable of contacting at least a portion of the inner surface of a container neck, when said cap body (2) is coupled to said container.

  • Such stiffening, resistance to deflection and shape may become particularly important when tightening or over-tightening of the cap body (2) occurs. Strong tightening of the cap body (2) onto a container neck may be required in order to maximize the sealing capabilities of said cap body (2) and to prevent accidental unscrewing from said container neck.

  • a lubricating additive may be added to the resin of the cap body (2), lid (3) and locking means where the greatest contact occurs.
  • said lubricating additive is selected from the group consisting of erucamide, siloxane and mixtures thereof.
  • the panel (25) may be further connected to the lid (3) by a second material having a lower elastic deformation than the elastically deformable material (28), preferably said second material is the same material of said lid (3).
  • the panel (25) may be connected to the lid (3) by said second material at two discrete locations, one on each of the two sides of the panel (25) parallel and mirrored to each other such to form two parallel pivot points for rotation.
  • the remaining portions of the panel may be connected to the lid (3) via the elastically deformable material (28).
  • the two discrete locations are proximal to the bottom of the panel (25) and distal from the top of the panel (25) such that a greater rotational arm is formed between the two parallel pivot points and said top of the panel (25).
  • the elastically deformable material (28) covers at least one face of said panel (25), preferably the face onto which the user applies pressure thereon, more preferably the face pointing away from the inside of said lid (3).
  • said elastically deformable material (28) may comprise indicia on at least part of its surface, preferably the surface onto which the user applies pressure thereon with one or more fingers.
  • said indicia may indicate the optimal position onto which the user should press to achieve unlocking with the least possible effort.
  • Fig. 8A-C illustrate an example of the operation of the cap (1).
  • Fig. 8A illustrates the resting position of the cap (1) in its closed position, prior to use.
  • the user disengages the lid (3) by applying a pressure, preferably in the radial direction, onto at least a portion of the panel (25) forming part of the locking means with one or more fingers.
  • the direction and location of the pressure is indicated in Fig. 8A by the arrow A.
  • This pressure causes the plate () to rotate upon an axis perpendicular to the longitudinal axis (YY) such that the protrusion (26) exits the slot
  • Fig. 8B illustrates the disengagement of the protrusion (26) from the slot (27). The user may now apply a substantially upward pressure to lift the lid (3) to its fully open position for pouring of the content of the container connected thereto.
  • Fig. 8B illustrates both the radial pressure of smaller magnitude A' and the upward pressure B.
  • Smaller magnitude as used herein it is meant that the magnitude of the radial pressure applied when the protrusion (26) and slot (27) have disengaged is less than the radial pressure applied before said disengagement.
  • Fig. 8C illustrates the cap (1) in its fully open position.
  • the lid (3) may be closed singlehandedly by pushing said lid (3) back onto the cap body (2) until the protrusion (26) snaps back into the slot (27) to lock the cap (1) in its closed position. The operation may be repeated for subsequent uses.
