Definitions

  • the present invention relates to a drip-catcher for insertion into a neck of a bottle according to the preamble of claim 1.
  • the resilient flexible sheet material is usually a suitable thin laminated plastics material, which is rolled into a tubular shape before insertion into the bottle neck.
  • the thickness and resiliency of the plastics material are chosen in such a way that the piece of material, when rolled into the tubular shape, tends to unroll so as to assume again its original planar shape and as a result tightly engages the cylindrical inner surface of the bottle neck. In this way the drip-catcher adapts itself to differing interior diameters of an existing range of bottle necks.
  • the tubular drip-catcher is only partially inserted into the bottle neck so that it will project from the bottle neck and form a pouring spout for the liquid.
  • the drip-catcher has a circumference with a relatively sharp edge and two opposite fluid repellent surfaces so that it will enable a drip-free pouring of liquid and will prevent any drops from falling from the pouring spout or from seeping down on the outside of the bottle.
  • the wine is normally poured into a glass decanter with a form that will keep the residues back when pouring the wine and that will increase the surface area of the wine in contact with air.
  • EP 1 165 393 B1 discloses such a pourer which is capable of drawing air into the flow of liquid passing through the pourer and of mixing the air with the liquid within the pourer.
  • the pourer comprises an elongated annular body which is adapted to be inserted into a bottle neck, the annular body defining a longitudinally extending through-going channel and having an air intake opening extending transversely to the channel and penetrating the body, so as to allow air to be sucked into the channel when liquid is flowing from the container through the channel.
  • the channel defines a contraction near the air intake opening like in a Venturi-arrangement.
  • the piece of sheet material is provided with a plurality of cuts and fold lines which delimit integral portions of said piece of sheet material. After having rolled the piece of sheet material from its original planar shape into a tubular shape and after having inserted the tubular piece of flexible sheet material into the bottle neck, these integral portions are apt to project into a hollow interior of said tubular roll and to create obstacles in the liquid flow through said tubular roll during pouring.
  • the effect of the obstacles in the liquid flow through the pourer or drip-catcher is similar to the effects of boulders in a rapid of a river: Due to the flow of liquid around such obstacles swirls, eddies and turbulences will arise behind the obstacles and due to the flow of liquid over the obstacles small falls and eddies will arise behind the obstacles. Both effects will mix the liquid with air. A further effect of the obstacles will be an increase of the velocity of the liquid flow passing the obstacles which will also enhance turbulence in the liquid flow. When the drip-catcher according to the invention is used for pouring wine from a bottle these effects will result in an aeration of the wine due to the mixing of wine and air.
  • the portions forming the obstacles in the liquid flow and the remainder of the piece each have two opposite surfaces which are flush or lie in the same planes, when the piece is in the planar shape, i.e. before use.
  • the drip-catcher preferably does not have any overlapping portions but is a single layer of the sheet material where the portions forming the obstacles in the liquid flow are separated from the remainder of the piece by the cuts and the fold lines so that they can be deformed after having rolled the piece of sheet material into a tubular form. In this way the portions can be simply stamped from the sheet material during production of the drip-catcher.
  • the opposite surfaces of the portions forming the obstacles in the liquid flow are preferably inclined with respect to the main direction of the liquid flow through the tubular roll in order to increase the resistance of these portions to the liquid flow, whereas the opposite surfaces of the remainder of the piece are essentially parallel to the main direction of the liquid flow through the tubular roll when liquid is poured through the drip-catcher.
  • the inclination of the opposite surfaces of the portions forming the obstacles with respect to the longitudinal axis of the tubular roll is preferably more than 30 degrees, and more preferably from 60 degrees to 90 degrees. A relatively steep inclination will result in the formation of small falls of liquid passing over the obstacles which will enhance the mixing of air and liquid downstream of the obstacles.
  • the inclination can be even more than 90 degrees in order to create an overhang on the downstream side of the obstacles.
  • the portions projecting into the interior of the tubular roll and forming the obstacles for the liquid flow are only partially immersed in the liquid flow so that part of the liquid will flow around the obstacles and part of the liquid will flow over the obstacles.
  • another part of the liquid will pass below the obstacles so that the liquid flowing over the obstacles will fall onto the liquid passing below the obstacles.
  • the portions forming the obstacles are partly delimited by fold lines which will act as hinges when deforming the portions such that they are apt to project into the interior of the tubular roll and do not return in the position before deformation.
  • the integral portions After having deformed the integral portions holes or openings will be left in the piece of sheet material where the portions have been situated before in the planar shape of the piece.
  • none of the portions forming the obstacles is provided in the pour spout, i.e. the part of the drip-catcher or pourer projecting from the bottle neck.
  • the portions forming the obstacles are only provided on the part of the drip-catcher or pourer which is inserted into the bottle neck.
  • the arrangement of the portions forming the obstacles on the piece of sheet material is such that during the pouring of liquid from the bottle they will project upwardly into the interior of the tubular roll or into the liquid flow.
  • the portions are preferably arranged along a linear central axis of the piece which, after deforming the piece into the tubular roll, will be essentially parallel to a longitudinal axis of the tubular roll.
  • said portions are symmetrical to a linear central axis of the piece.
  • the portions forming the obstacles are preferably elongated strips having two opposite ends connected by fold lines to the remainder of the piece of sheet material and being delimited on opposite sides by cuts which preferably have a shallow V-shape or U-shape when the piece of sheet material is in its planar shape.
  • the strips are provided between their two opposite ends with at least one further transverse fold line, preferably one central fold line in the middle, which divides each strip into two halves.
  • the second orientation of the strips is preferably an angular orientation where two adjacent sections of the strips which are connected by a fold line are inclined with respect to each other and with respect to the direction of the liquid flow.
  • each of the two sections has two essentially planar opposite surfaces which are not only inclined with respect to the opposite surfaces of the other section but also with respect to the main direction of the liquid flow within the tubular roll.
  • the piece of sheet material is provided with a plurality of elongated strips which project into the interior of the tubular roll and form the obstacles.
  • the strips are arranged along a linear central axis of the piece of sheet material so that the obstacles created after deforming the strips are arranged one behind the other in the main direction of liquid flow through the tubular roll when pouring.
  • a fold line in the middle of each strip is aligned with the linear central axis of the piece of sheet material whereas the two fold lines at the opposite ends of each strip are inclined with respect to the linear central axis of the piece of sheet material.
  • the inclination is such that the opposite fold lines will converge in a direction towards the part of the piece of sheet materials which is used as pouring spout, i.e. the part which will project from the bottle neck and is not provided with an elongated strip or other portion forming an obstacle.
  • the angle of inclination of the two opposite fold lines with respect to the linear central axis of the piece of sheet material is preferably between 10 and 45 degrees and will determine the flow resistance of the strips which will reach a maximum when the angle of inclination is about 45 degrees.
  • the piece of sheet material of the drip-catcher has a circular outline.
  • the shape or outline of the piece of sheet material can be chosen at will.
  • an outline with a continuous convexly rounded curvature is preferred.
  • the drip-catchers 10 as depicted in Figures 1 to 11 of the drawing each consist of a circular piece 12 of a laminated resilient sheet material.
  • the sheet material is a laminated plastics material, which comprises two surface layers of PET (Polyethylenterephthalate) and possibly a thin metal and/or printed layer between the two surface layers.
  • the sheet material has a suitable flexibility and elasticity so that the drip-catchers 10 can be easily rolled from the planar shape, as depicted in Figures 1, 2 , 8 and 9 , into a tubular shape or roll 14 as depicted in the other Figures.
  • In the tubular shape two opposite rim portions 16, 18 of the circular piece 12 will overlap each other, as can be best seen in Figures 5 , 7 , 10 and 11 .
  • the drip-catcher 10 can be partially inserted into the neck of a bottle (not shown), for example a wine bottle, where it can serve both as a pourer for enabling drip-free pouring of wine from the bottle and as an aerator for aerating the wine when it flows through the hollow interior of the tubular piece 12 of sheet material during the pouring operation.
  • a bottle for example a wine bottle
  • the drip-catcher 10 can serve both as a pourer for enabling drip-free pouring of wine from the bottle and as an aerator for aerating the wine when it flows through the hollow interior of the tubular piece 12 of sheet material during the pouring operation.
  • the drip-catcher 10 After letting go the partially inserted drip-catcher 10 within the bottle neck due to the resiliency of the piece 12 of sheet material the drip-catcher 10 will tend to assume its original planar shape. As a result the cylindrical outer surface 20 of the tubular roll 14 will tightly and sealingly engage the cylindrical inner surface of the bottle neck. The friction between the two surfaces will hold the drip-catcher 10 within the bottle neck when pouring wine from the bottle.
  • the part of the tubular roll 14 which projects from the bottle neck forms a pouring spout 22 having a convexly rounded thin and sharp edge 24 which is part of the circumference of the piece 12 of sheet material. This edge 24 will efficiently cut off any liquid flow when the bottle is returned to an upright position after the pouring operation. The cutting off will prevent the formation of drops at the mouth of the bottle neck, which would otherwise seep down on the outside of the bottle.
  • the drip-free pouring is assisted by a liquid repellent surface characteristic of the laminated sheet material.
  • the bottle When pouring wine from the bottle the bottle is held in such an orientation that the convex edge 24 of the pouring spout 22 will be in the lowermost position of the tubular roll 14 such that the wine will flow over the edge 24. In this orientation of the bottle the two overlapping rim portions 16, 18 of the piece 10 will be in the uppermost position of the tubular roll 14 inserted into the bottle neck.
  • planar piece 12 of sheet material of the drip-catchers 10 is provided with a plurality of integral portions 26 which are each delimited by two cuts 28 and by two fold lines 30.
  • the cuts 28 and the fold lines 30 are made by stamping during the production of the drip-catchers 10 when the piece 12 is cut from a blank or from continuous roll of the sheet material.
  • Each drip-catcher 10 depicted in the drawings has a total of five pairs of cuts 28 where each alternate pair delimits one of the deformable portions 26.
  • the number of cuts 28 and therefore the number of portions 26 can be higher or lower.
  • the portions 26 are in the form of elongate narrow strips which are lined up along a linear or diametrical axis 32 through the centre of the circular piece 12 which intersects the strips 26 and divides them in two halves which are symmetrical to the axis 32.
  • the strips 26 are disposed in equal distances however are not equally distributed across the circular piece 12 but are disposed along a length of the axis 32 which length will be within the bottle neck after the drip-catcher 10 has been partially inserted into the latter. In other words the pouring spout 22 which projects from the bottle neck is not provided with any of the strips 26.
  • the two opposite surfaces 34, 36 of each strip 26 are flush with the adjacent surfaces 38, 40 of the remainder 52 of the piece 12 as can best seen from figures 2 and 9 .
  • the surfaces 34, 38 and 36, 40 are in one plane, so that there is no overlapping of the strips 26 with the remainder 52 of the piece 12.
  • each cut 28 has the form of a shallow V and accordingly each strip 26 has an outline in the form of a shallow V. Neighbouring strips 26 are separated by elongate bridges 48 in the form of a shallow V and having a slightly narrower width.
  • the apexes 44 of the pair of cuts 28 which delimit each strip 26 point away from the part of the piece 12 which will form the pouring spout 22 and are connected by an additional fold line 46.
  • the additional fold lines 46 are aligned with the axis 32.
  • the two fold lines 30 at the opposite ends of each strip 26 converge towards the pouring spout 22 and are inclined with respect to the axis 32. In the embodiment in Fig. 1 the angle of inclination ⁇ is about 45 degrees, however ⁇ can be more or less than 45 degrees.
  • the lengths of the strips 26 increase along the axis 32 in the direction of the pouring spout 22.
  • the elongate strips 26 can be deformed from a first position (not shown), where their opposite surfaces 34, 36 are still aligned with the adjacent surfaces 38, 40 of the remainder 52 of the piece 12, into a second position where the strips 26 will project into the interior of the hollow tubular roll 14.
  • the deformation of the strips can be done by pushing them inwardly with respect to the remainder 52 of the rolled up piece 12.
  • each strip When the strips 26 are deformed into their second position each strip will leave a hole or an opening 50 the rim of which is formed by the two cuts 28 and the two fold lines 30 delimiting each strip 26.
  • the second position is a stable position where the strips 26 will remain as long as the drip-catcher 10 is in its tubular shape during use, which is partly due to the fold lines 46. However when the drip-catcher 10 is taken from the bottle neck and resumes its original planar shape the strips 26 will automatically return to their first position
  • each strip 26 will assume a V-shape where the two opposite surfaces 34, 36 of each strip 26 or of the two halves of each strip at either side of the fold line 46 respectively are steeply inclined with respect to the direction of flow and where the apexes 44 of the cuts 28 point into the flow direction.
  • the inclination of the surfaces 34, 36 with respect to the main direction of flow F through the tubular roll is about 85 degrees.
  • the flow of wine will normally amount to less than half of the interior of the tubular roll 14, whereas the other half, or more, is filled with air entering the bottle in order to replace the poured wine.
  • some of the wine will pass beneath the strips 26 or obstacles and will flow across the holes or openings 50.
  • some of the wine will pass over the strips 26 or obstacles. This will create small falls and turbulences behind the strips 26 or obstacles and will increase the velocity of the flow passing the strips 26 or obstacles.
  • the inclination of the surfaces 34, 36 with respect to the main direction of flow F can be even more than 90 degrees in order to create an overhang on the downstream side of the strips 26.
  • each strip 26 is delimited by two cuts 28 having a shallow convex curvature facing away from the pouring spout 22. Furthermore the two fold lines 30 at the opposite ends of each strip 26 are inclined to the axis 32 at a relatively small angle ⁇ of less than 10 degrees.
  • each strip 26 After having deformed each strip 26 into the second position the opposite surfaces 34, 36 of each strip 26 will be nearly parallel to the direction of flow as can be best seen in Fig. 10 . Due to this the aeration of the wine will be much less pronounced. Therefore in order to achieve a higher rate of aeration the angle ⁇ enclosed by the fold lines 30 and the axis 32 should be more than 20 degrees.
