Definitions

  • the present invention relates generally to the field of containers for food liquids, and in particular to an object comprising a sleeve and a bottle (typically made of plastic) and a food liquid such as still mineral water.
  • the invention also relates to a method of delivery to a consumer.
  • minimizing the thickness of these bottles can be advantageous (economically or environmentally), but it's essential to ensure the bottle remains easy to handle and doesn't deform excessively when held by a consumer (typically with a force of 20 newtons). This is particularly important for small-capacity bottles (less than 2 liters, preferably less than 1.5 liters or even 1 liter), as these are intended to be carried by the consumer, and there is a risk of deformation (which (which leads to overflow if the consumer squeezes the bottle tightly) must be minimal.
  • One aim of the present invention is to address the drawbacks of the prior art documents mentioned above and in particular, first of all, to offer a bottle which forms a product by containing a food liquid which minimizes the ecological impact, which is cheap to produce, without degrading the ergonomics or the use by the consumer, who must be able to handle the bottle without taking any special precautions, and without risking spilling the liquid contained.
  • a first aspect of the invention relates to an object to be held by a consumer, comprising: - an external rigid sleeve arranged to be held by the consumer, - a closed thin-walled plastic bottle, in which the bottle has a cylindrical body arranged between a neck and a base, in which the cylindrical body of the bottle is flexible and has a thickness in a range from 30 ⁇ m to 150 ⁇ m, in which the external rigid sleeve includes a lower opening arranged to receive the bottle, and in which at least a first portion of the external rigid sleeve cooperates with a first portion of the cylindrical body of the bottle received by the opening, to form means for locking the bottle in the external rigid sleeve.
  • the sleeve includes a lower opening, allowing for easy insertion of the bottle.
  • the invention provides locking mechanisms to secure the inserted bottle, enabling the consumer to handle the entire assembly via the sleeve, which deforms little or not at all, and without the bottle falling. Because this rigidity is transferred to the sleeve, it is possible to offer a thin-walled bottle that does not need to guarantee high rigidity, thus drastically reducing the amount of material, up to 50% compared to a prior art bottle. This helps to limit the impact environmental, because the bottle is disposable and recyclable, and the sleeve can be used many times.
  • the locking mechanism is operated by the consumer, that is, the person who will consume the food liquid.
  • the invention can be implemented by a user who is not the consumer.
  • the locking means are a screw coupling, the first portion of the bottle comprising at least one thread formed on at least one part of the cylindrical body of the bottle, and the sleeve comprising at least one tapped hole arranged to cooperate with the thread of the bottle.
  • a screw coupling is easy and convenient for the consumer to perform.
  • a thread on the (cylindrical) body of the bottle is also easy to produce, as it consists of one or more helical ribs running along the body of the bottle, or along at least one part of the body.
  • the thread has a thread depth of at least 1 mm, preferably 1.5 mm, and even more preferably 2 mm.
  • a thread depth of more than 2.5 mm can even be considered.
  • a symmetrical, or even asymmetrical, thread profile can also be considered to more effectively absorb downward forces.
  • the first section of the bottle has at least two threads. This creates a multi-threaded "screw,” increasing the pitch and reducing the number of turns required by the consumer: locking is even faster.
  • the locking means are an elastic interlocking coupling
  • the first portion of the outer sleeve includes at least one protrusion arranged on an inner wall facing the opening
  • the first portion of the bottle includes at least one groove
  • the peripheral device is designed to fit onto the protrusion of the external sleeve. Locking is achieved simultaneously with the insertion of the bottle into the sleeve, preferably at the end of its travel.
  • the outer sleeve includes at least one means of indexing the bottle for rotation. This allows the bottle cap to be screwed and unscrewed without risk of accidental rotation between the bottle and the sleeve.
  • the bottle includes a neck
  • the sleeve indexing means includes at least one index or protrusion arranged to engage with a portion of the bottle neck.
  • Such an index arranged at the neck (which is by definition rigid) makes it possible to limit the stresses on the locking means formed by a thread or elastic clip/fit on the body, which is by definition flexible.
  • the sleeve includes a constriction opposite the opening, designed to form an axial stop for the bottle received in the opening.
  • This stop allows for intuitive use: simply push the bottle into the sleeve until it reaches the constriction, and then simultaneously lock the bottle in place.
  • the sleeve has an opening at the constriction, arranged to allow the neck of the received bottle to pass through the opening.
  • the sleeve is a piece open at both ends and has a wall that is at least partly cylindrical to be grasped by the consumer.
  • the bottle has a cylindrical section.
  • a cylindrical wall or section is defined as a portion of a sleeve or bottle with a lateral surface whose generatrices are parallel lines, and which follows a base curve (defined by the intersection of the lateral surface with a plane perpendicular to an axial direction of the bottle) that is a closed curve.
  • This closed base curve may be circular (a circle), oval (an ellipse or any oval shape), square, or rectangular, possibly with rounded corners.
  • Such a section of the cylindrical part can improve grip, limit flexibility and/or limit the risk of leakage when opening the bottle.
  • the bottle is made of polyethylene terephthalate (PET).
  • PET polyethylene terephthalate
  • the bottle comprises a body that is at least partly cylindrical.
  • the product includes bottle closure means, such as a screw-on or snap-on cap, a foil seal, or a valve.
  • the closure means may also include tamper-evident features, such as a tamper-evident ring attached to the cap by tabs that must be broken upon first use. Alternatively, it may include a foil seal on the neck, which must be permanently removed upon first use.
  • the closure means may, where appropriate, include reversible features allowing the bottle to be resealed after first use. This is the case, for example, with screw-on and screw-off caps. It is specified that the filled bottle is preferably closed with a screw-on or snap-on cap equipped with a tamper-evident ring whose tabs are not broken.
  • the object includes a drinkable liquid filling at least 80% of an internal volume of the bottle, preferably water, preferably non-carbonated.
  • the sleeve includes means for recognizing the bottle, and/or means of communication to send information to the consumer, and/or a human-machine interface arranged to receive an order from the consumer.
  • only one sleeve is supplied for a batch of bottles.
  • Delivering a batch of bottles with only one (or a small number of) sleeves saves material on each bottle, while providing the possibility of coupling with a reusable sleeve that is rigid enough to ensure good ergonomics.
  • filling is preferably carried out cold (below 50°C), so the bottle is not intended to compensate for a pressure/volume variation caused by a temperature variation during cooling.
  • FIG. 1 represents three views of a first embodiment of an object according to the present invention, which includes a bottle 11 closed by a cap 12 (thus forming a closed container which contains a food liquid), visible from left view, and a sleeve 20 visible from middle view.
  • the bottle 11 has a neck (closed by the cap 12), a rim, a substantially cylindrical body, a base, and contains a food-grade liquid (for example, still mineral water).
  • the substantially cylindrical body includes a thread 111.
  • the sleeve 20 comprises an upper constriction with a top opening, a substantially cylindrical body, and a bottom opening.
  • the view from the middle of the figure 1 also shows a tapped hole 201 arranged on an internal wall of the sleeve 20 and therefore visible in dotted lines.
  • the view from the right of the figure 1 shows the bottle 11 which has been inserted into the sleeve 20 by a consumer, then screwed so as to come to a stop against the constriction of the sleeve 20.
  • the bottle 11 is locked onto the sleeve 20, so that the consumer can hold the object (the sleeve 20 + the closed bottle 11 + the liquid contained) only by the sleeve 20.
  • FIG. 2 represents three views of a second embodiment of an object according to the present invention.
  • the object to be held by a consumer includes an 11A bottle (left view of the figure 1 ), intended to be inserted into a 20A sleeve (visible when viewed from the middle of the figure 2 ).
  • Bottle 11a is always closed by a cap 12, and also contains a food-grade liquid (for example, still mineral water).
  • a food-grade liquid for example, still mineral water
  • bottle 11A has a peripheral groove 111A in the upper part of its cylindrical body, and sleeve 2A also has a peripheral groove 201A which defines a protrusion on its inner wall, as shown by the dotted lines in the middle view.
  • a rotation stop can be implanted between the bottle 11A and the sleeve 20A, for example in the form of an index or flutes, or grooves (complementary or not) between the bottle 11A and the sleeve 20A, in particular at the upper opening of the sleeve 20A which is opposite the neck of the bottle 11A, which is typically more rigid than the rest of the bottle 11A.
  • the sleeve 20 or 20A is advantageously quite short, but long enough to be held by the consumer (at least ten centimeters long for example), while the bottle 11 or 11A protrudes from the sleeve 20 or 20A so that it can be inserted or removed easily.
  • a strap, wrist strap, or textile hook and loop fastening bands can also be provided to allow the consumer to carry the item in various activities (sports, hiking).
  • the base is concave in a relaxed state, and that the consumer, by pressing on it, can move it into an activated state so that the base has a convexity, which then allows the object to be placed on a work surface.
  • such a concave bottom forms an activatable portion with a concavity oriented along a first direction in a relaxed state, the activatable portion being arranged to deform under an effort exerted by a consumer to pass into an activated state and exhibit a convexity oriented in a direction opposite to the first direction.
  • bottle 11 it can therefore be inserted and locked into sleeve 20 with the activatable portion in a relaxed state, and then the activatable portion can be moved to an activated state, which "tensions” and inflates the cylindrical portion of bottle 11, so that bottle 11 is even more locked in sleeve 20.
  • the activatable portion of the bottle is arranged to be activated directly by the user (for example by a push exerted by the user's hand or fingers directly on the activatable portion).
  • the activatable portion is designed to remain in that state, even if it is not in contact with a surface or worktop.
  • the activatable portion is designed to remain in the activated or relaxed (non-activated) state until pressure is applied by the user to change its state.
  • the activatable portion is advantageously adjacent to the cylindrical portion. This allows, on the one hand, for the cylindrical portion to be effectively tensioned when the activatable portion is activated, and on the other hand, ensures that the activatable portion will remain activated, since a fold along the perimeter of the cylindrical portion will be more resistant. In particular, the weight of the liquid in the bottle is insufficient to cause the activatable portion to transition from the activated to the deactivated state.
  • the 11 or 11A bottle is made of a thin-walled thermoplastic material.
  • the material is preferably a polyester such as polyethylene terephthalate (PET), polytrimethylene terephthalate (PTT), polyethylene furanoate (PEF), or polytrimethylene furanoate (PTF). It is preferably formed by an injection blow molding process, for example, an injection stretch blow molding process. In these processes, a solid preform is manufactured by injecting the material in a mold and then cooled, the preform is then heated to soften it, possibly stretched longitudinally using a rod, then stretched axially and longitudinally by blowing into a mold shaped like the bottle.
  • polyester materials and processes are well-known to those skilled in the art. Their combination makes it possible to obtain thin, lightweight walls with good mechanical strength and sealing or other barrier properties. These properties are due to the orientation of the macromolecular chains, which induces at least partial crystallization. In addition to material savings, these polyesters have the advantage of being easily recyclable. Recovery, sorting, and regeneration channels are well-established. Regeneration can be mechanical recycling involving melting and shaping, for example into granules before further plastics processing operations such as injection blow molding, or chemical recycling involving depolymerization, recovery of monomers or precursors, and then repolymerization.
  • the implementation and use of the thin-walled bottles of the invention therefore presents a very advantageous environmental balance, in addition to good practicality, particularly compared to the implementation of conventional non-activatable, thicker PET bottles.
  • the thin wall is such that the bottle body has a thickness in the range of 30 ⁇ m to 150 ⁇ m, for example, in the range of 30 ⁇ m to 50 ⁇ m, or 50 ⁇ m to 70 ⁇ m, or 70 ⁇ m to 100 ⁇ m, or 100 ⁇ m to 125 ⁇ m, or 125 ⁇ m to 150 ⁇ m, preferably in the range of 100 ⁇ m to 125 ⁇ m.
  • the thickness mentioned is the thickness at at least one point on the body, preferably the average thickness over a portion representing at least 50% by length or surface area of the body, preferably at least 80%, preferably the average thickness over the entire body.
  • the bottom of the bottle may have a thickness slightly greater than that of the body, for example, up to 50% greater than that of the body, or up to 20% greater.
  • the base may also have a cup, typically corresponding to the base of the preform and its injection point.
  • the thickness can be adjusted by adapting the preform's characteristics, particularly its shape and wall thickness, as well as its drawing characteristics, for a target bottle volume. It is noted that the preform's wall thickness, geometry (such as its length, diameter, and base shape), along with the neck (which will form the bottle's neck), determine the weight.
  • the unfilled, unsealed bottle and/or the preform generally have the same weight. Therefore, the weights given hereafter refer interchangeably to the bottle weight or the preform weight.
  • preforms weighing 8 to 13 g can be advantageously used.
  • the overall drawing ratio can, for example, be between 12.0 and 27.0, preferably between 15.0 and 20.0.
  • the axial stretch ratio (typically the ratio between the height of the bottle and the length of the stretchable portion of the preform, typically the distance below the neck) can, for example, be between 3.0 and 4.5.
  • the radial stretch ratio (typically the ratio between the diameter of the bottle and the diameter of the stretchable portion of the preform) can, for example, be between 4.0 and 6.0. It is noted that the overall stretch ratio is generally equal to the product of the axial stretch ratio and the radial stretch ratio.
  • Preform type Preform featuring a non-stretched screw-threaded neck and collar
  • Preform weight 12.8g Neck weight 3.68g
  • Overall stretch rate 17.96
  • Radial stretch ratio 4.35
  • Axial stretch rate 4.13 Thickness at the body 110 ⁇ m
