Definitions

  • the present invention relates to a large size thermoplastic container for containing and distributing liquids, in particular potable liquid products.
  • liquids in particular potable liquids or beverages, such as water, are typically preserved and distributed in plastic containers.
  • large size containers or bottles are used, which have capacities generally from 5 liters to 25 liters, and may be either disposable or reusable after suitable treatment.
  • the large bottles in particular the 10 liter to 19 liter bottles, are used with specific dispensers, e.g. water dispensers, which can also cool the content of the bottle.
  • specific dispensers e.g. water dispensers
  • thermoplastic materials such as polyethylene terephthalate (PET), polycarbonate (PC), polystyrene (PS), etc.
  • Relatively thick walls are also necessary because the container must be able to sustain the external pressure while it is being emptied, before air enters into the container to replace the dispensed liquid.
  • This problem is particularly related to containers made of PET.
  • returnable containers must be properly washed before they can be used again. For these reasons, returnable containers are rather expensive, heavy, difficult to handle, and involve sanitary problems. Therefore, it is not always economical to make returnable containers having thick, robust walls.
  • Disposable containers are also used as alternatives to reusable containers and manufacturers have a strong interest in reducing the weight of containers of this type, which are usually transported on pallets, in order to reduce the consumption of thermoplastic material, principally PET, which is chosen because of its high strength.
  • US 2011 /0036806 discloses a small sized bottle, i.e. having a capacity of up to 2 liters, designed to collapse after being emptied in response to an axial crushing force, in particular by applying an axial compressive force and an axial rotation.
  • the bottle is collapsed by twisting and pushing the bottle along its axis.
  • the collapse is promoted by a concertina portion provided with a number of collapse initiators which are circumferentially staggered.
  • This bottle is not adapted to be used with a liquid dispenser and said forces are different from the atmospheric pressure.
  • WO 2010007744 discloses a bottle for water dispensers which can reduce its volume due to a concertina portion between a top and bottom portion. Such document does not disclose a specific design for the concertina portion, but it teaches that the height of the bottom portion has to be 60-80% of the height of the concertina portion. However, such bottle still leaves room for further improvements. For example, it has been noted that the concertina portion does not allow for a gradual and controlled collapse of the bottle and the bottle tends to assume its original shape mainly due to the memory of the material.
  • thermoplastic container which is light and has thin walls, like those which can be achieved by using PET or another thermoplastic material having the same features, which does not suffer from the aforesaid disadvantages and which collapses during emptying in a controlled manner.
  • a self-collapsible container according to claim 1 made of PET, adapted to be filled with a liquid and to be and to be used in an upside-down position with a potable liquid dispenser, having a capacity of at least 5 liters, defining a longitudinal axis X and comprising:
  • central body is provided with a plurality of adjacent ribs substantially parallel to a plane perpendicular to said longitudinal axis, each of said ribs having
  • first straight portion of a rib and the second straight portion of the adjacent rib facing the first straight portion form a first angle C comprised between 10°- and 90 Q ;
  • the concave root portion has a first radius of curvature B comprised between 0,2 and a 1 mm;
  • the maximum dimension P measured along a line perpendicularly crossing the longitudinal axis X, between the crest and the concave root portion, is comprised between 5 mm and 8 mm;
  • the second straight portion is shorter than the first straight portion 6;
  • a line Y perpendicular to the longitudinal axis X and passing through the concave root portion divides the first angle C into a second angle C1 defined by the second straight portion and the line Y, and a third angle C2 defined by the first straight portion and said line Y, the second angle C1 being smaller than the third angle C2,
  • the container gradually collapses axially reducing its volume with respect to its original shape, the collapsing occurring as result of the force generated by atmospheric pressure due to the difference between external and internal pressure.
  • the capacity of a container of the invention is in the ranges from 5 liters to 25 liters, for example from 10 liters to 19 liters.
  • the radius of curvature A is comprised between 4 mm and 8 mm, more preferably between 5 mm and 7 mm.
  • the radius of curvature B is comprised between 0,4 mm and 0,6 mm.
  • the angle C is comprised between 12- and 80 Q , or between 72° and 76°
  • the ratio C2/C1 i.e. between the third angle C2 and the second angle C1 , is between 2,5 and 5,5, more preferably between 3,5 and 4,5, for example about 4.
  • the length of proximal, or first, straight portion is at least four or at least five or at least six times greater than the length of the distal, or second straight portion; Best results are obtained when the length of the proximal straight portion is at least five times, preferably about six times, the length of the distal straight portion.
  • the maximum dimension P is comprised between 6 mm and 7 mm.
  • the crest further comprises a third straight portion, adjacent to the first rounded portion, and a second rounded portion, between the third straight portion and the second flank.
  • the central body Preferably, from 85 to 95 % of the longitudinal height of the central body is provided with ribs.
  • the ratio Weight/Volume of the container without taking into account the weight of the neck is between 6,5 and 9, where the weight is in grams and the volume is in liters. This means that the walls are very thin.
  • the wall thickness of the central body is between 0,10 and 0,20 mm, although it can be lower than 0,10 mm.
  • Such a thin wall thickness contributes to allow a controlled, gradual collapse effect as liquid is emptied from the container.
  • the wall thickness can be substantially constant, or can vary from 0,10 to 0,20 mm going from the rib adjacent to the shoulder to the rib adjacent to the base. Such increase in wall thickness can be gradual or not.
  • the half of the central body proximal to the neck can have a wall thickness which is 50-60% of the wall thickness of the half of the central body distal from the neck, e.g. 0,10 and
  • the central body is the lightest portion of the container, and preferably also the largest.
  • the present invention overcomes the problems of the prior art by taking advantage of the vacuum pressure itself. Indeed, it is designed not to resist said pressure, but to collapse in a controlled, gradual manner during the drop of internal pressure caused by the dispensing of the liquid therein contained. In other words, when the water flows out of a container according to the invention, the latter collapses in a controlled manner.
  • the container shrinks to an external volume which is less than 20-25% of its original volume, i.e. when it was substantially full of water.
  • the container of the invention collapses vertically along its longitudinal axis as the water flows out, thus reducing its height by virtue of the particular design of the ribs which allow the container to collapse in a controlled manner.
  • the volume reduction of the container is advantageously permanent, since the container can recover its original shape only if an external pulling, i.e. traction force is applied. In other words, the possible recovery is not because of the shape- memory of the thermoplastic material.
  • This permanent deformation is mainly due to the particular design of the ribs, which can get stuck into each other, and is not possible with the prior art containers with a concertina portion.
  • the container when mounted in an upside down position on a conventional water dispenser, i.e. with the neck pointing downwards, in order to compensate for the variation of internal pressure in the container due to the portion of liquid dispensed from the container, the container will gradually collapse, the collapsing occurring as result of the force generated by atmospheric pressure due to the difference between external and internal pressure, thus reducing only the upper portion void of the liquid, and therefore only the longitudinal height of the container, in a controlled manner, while the part of the container proximal to the neck, which still contains the liquid, maintains its shape.
  • the collapsing occurs only as result of the force generated by atmospheric pressure due to the difference between external and internal pressure.
  • the collapsing of the container is gradual, or sequential, i.e. the collapsing starts at the rib which is adjacent to the bottom, then occurs at the adjacent one, and so forth, the motion becoming continuous as the water is dispensed, and this movement will continue until the collapsing of the rib adjacent to the shoulder.
  • a self-collapsible container according to the invention is lighter, and has thinner walls than the typical non-collapsible container which has to resist the vacuum pressure.
  • the weight of a 12 liters bottle can be of 135 g or less, where such weight takes into account the weight of the neck.
  • the collapsible containers according to the invention are light in weight particularly due to their design which allows the use of thin walls while achieving excellent operational performances.
  • these containers can be placed in cardboard boxes to be transported.
  • these containers allow a high cost reduction of the polymeric material: at least 50% less polymer is used than in the designs of containers with walls made to resist vacuum pressure.
  • Another advantage of a light-weight-self-collapsible container is the reduction in energy consumption and the lower amount of plastic which needs to be recycled, thus reducing its impact on environment.
  • thermoplastic materials such as PET allows to obtain peripheral walls which are thinner than those reachable by most other plastic materials.
  • the self-collapsible container of the invention is preferably made of PET and is particularly suitable for potable liquids or beverages. Furthermore, it is particularly suitable for water dispensers..
  • the ribs of a container of the embodiments illustrated in the following description have the same shape, i.e. the same profile on their projection on a plane coplanar with the longitudinal axis of the container. The only exceptions are the rib adjacent to the shoulder and the rib adjacent to the bottom, as described below.
  • the shape of the ribs can be the same or vary from one embodiment to another.
  • all the ribs i.e. also the rib adjacent to the shoulder and the rib adjacent to the bottom, can have identical shape, without departing from the scope of the invention.
  • the shoulder is provided with a plurality of grooves. These grooves, seen from a top view, have substantially radial extension, end extend inward in a direction along the longitudinal axis X towards the bottom of the container.
  • these grooves permit to use less material while preserving structural stiffness of the container.
  • the envelope of the crests and roots of the ribs is cylindrical.
  • the shoulder, central body, and bottom can have a circular, substantially square or polygonal cross section on planes orthogonal to the longitudinal axis, or combination thereof, for example, but not exclusively, square with rounded angles bottom and central body, and substantially circular shoulder.
  • the cross section is substantially square, or square with rounded, the wall thickness at the corners, or angles, of each rib, is greater than the remainder of the rib.
  • the envelope of the crests and roots of the ribs is frustoconical or frustopyramidal.
  • this configuration facilitates the collapse of the container in a controlled manner because the larger surface area of the bottom, which is the highest point of the container mounted on a water dispenser will collapse more easily onto the successive rib, thus facilitating the collapse of each rib onto the adjacent lower one.
  • the shoulder, central body, and bottom can have a circular, substantially square or polygonal cross section on planes orthogonal to the longitudinal axis, or combination thereof, for example, but not exclusively, square with rounded angles bottom and central body, and substantially circular shoulder.
