Definitions

  • the present invention relates to capsules containing an ingredient for the preparation of beverages within a closed chamber, which are opened through various strategies and opening elements.

  • the preparation of infusions such as tea is carried out by a leaching process whereby a fluid, usually water heated to a temperature below boiling, is passed through a bed of porous material, granular or chopped, so that a leachate is obtained that extracts part or all of its components.
  • a fluid usually water heated to a temperature below boiling
  • the principle of operation of this technology is based on carrying out an extraction process with a fluid (usually hot water) at constant pressure and temperature by using a capsule containing a pre-established dose of material. It typically consists of inserting a capsule into a receptacle or cavity of a machine, injecting an amount of pressurized water into the capsule, usually after drilling a wall of the capsule with an injection element such as a needle arranged in the machine, and creating in this way an interaction between the fluid and the ingredient, and then let the drink out of the capsule.
  • soft, semi-soft, semi-rigid or rigid capsules can be found.
  • Reusable capsules and disposable single-dose capsules after single use are also known.
  • the semi-soft, semi-rigid or rigid single-dose capsules are the ones that best guarantee the hygiene and preservation of the ingredient since with them a good barrier can be established to contain a conservation atmosphere in a closed chamber.
  • Single-dose capsules are elements that contain an ingredient that is extracted in the form of a drink when they collaborate with means external to them, such as an extraction device in which they are introduced or coupled.
  • an extraction device in which they are introduced or coupled.
  • These chambers may be inside the capsule, they may be formed by the capsule itself, or they may contain several capsules (such as a common container). In some cases, a waterproofing of liquids or moisture is sufficient, although in general the most common is the waterproofing of moisture and gases.
  • the waterproofing barrier be bidirectional effective, restricting both the entry and exit of gases or liquids. This type of insulation is common in those ingredients that are introduced into the capsule together with a conservation atmosphere, or in those ingredients that give off gases over time and that it is advisable not to let go.
  • the capsule is perforated with a perforator at one of its ends, where an extraction fluid is injected and the capsule is also perforated with another perforator at the opposite end, to open an outlet for the drink, which is led to a container.
  • the increase of hydraulic pressure inside is disregarded to move the walls of the same in order to open them and perforation elements integrated in the machine that are inserted in capsule are used.
  • a sample of these solutions are the capsules in which the closed chamber is defined by the capsule housing and an upper wall pierceable by a needle or fluid injection conduit.
  • the evacuation route of the beverage is formed in the lower part of the shell itself during the process of insertion or positioning of the capsule in the extraction machine.
  • the opening means are also based on the use of perforators or pushers, but now they are inside the capsule. Normally, the perforator or pusher also serves as a concentrator or dispenser, so that a single outlet jet is obtained that goes directly to the cup or container.
  • the wall of the base of the housing can be moved towards the inner perforator by applying pressure in said base towards the internal volume, as described for example in patent document EP 1580144 B l.
  • To open the capsule it is inserted into a capsule holder that is inserted into the machine or placed directly in a hole in the machine, being slightly raised.
  • the machine When the machine is closed on the capsule, it pushes it down, against the capsule holder or the hole in the machine, causing the housing to open internally.
  • Another way of provoking the perforation is with the displacement of the internal pusher or perforator towards the base of the housing using the movement of insertion of the needle or injection conduit that is placed in the machine.
  • An example of this technique can be seen described in WO 2008132571 Al.
  • the opening is made through the capsule shell by means of a perforator, spout or projection arranged in an inner pusher.
  • the capsule housings are made of plastic, such as PP, with a thickness that can be up to 1.5 mm.
  • the perforation of a plastic wall of these characteristics results in the need to apply a great penetration force, which implies that the closing of the machine on the capsule may require an overexertion that is not available to all users (such as children or the elderly) or that the design of the means of closing the machine on the capsule have to be very robust to withstand wear.
  • the opening force could be reduced at the cost of the perforator being a very sharp component, which makes it dangerous for the user as it is exposed after opening.
  • the type of opening in which the perforator is moved towards the housing when being pushed by means of injection or dispensing is only suitable for flat capsules, with a reduced height.
  • the perforator is a piece that has to open the capsule due to breakage or tearing of the lower part, where the beverage is produced.
  • the perforator is a part that is activated by contact with the injection means that penetrate the capsule at the top and normally have a travel capacity of a few millimeters. In order to activate the pusher or perforator and for it to tear the housing from the bottom, it is necessary that one end of the perforator be close to the top, which is where the injection media enters.
  • overexertion on the needle or conduit causes a problem of wear on the tip, which can affect the passage of fluid inside and the function of penetration and / or tearing of the needle in those capsules in which the needle must penetrate the top sheet. In the worst case, overexertion can cause elastic or even plastic flexion of the needle to such an extent that it makes the discharge dangerous due to blockage of the injection flow or that the machine is permanently damaged.
  • a technological alternative of the above capsules are those that continue to use closed chamber opening means integrated in the capsule itself but which are activated by increasing the hydraulic pressure inside the capsule, such as those described in EP1472156 B l, EP1864917 B l, WO 2006021405 A2 or WO 2014029884 Al.
  • Its operating principle is an evolution of the first capsules mentioned in this section, in which the opening is produced by direct interaction with pointed elements located in the extraction machine, outside the capsule.
  • the closed chamber with the ingredient is a subchamber inside the housing, with a top sheet and a bottom sheet.
  • the increase in hydraulic pressure inside the capsule causes it to either swell, pushing the lower wall of the closed chamber against opening means located outside it, or that opening means inside it move towards the bottom wall, so that they tear this membrane.
  • the opening means are placed inside the capsule housing and are in the form of blades, drills or projections. After opening the capsule, the beverage is conducted internally and exits directly from the capsule into a container or cup.
  • a typical configuration of this type of technology is the following: a hollow body or housing, usually in the form of a cup, and an injection wall that is impervious to moisture and air and is welded to the housing, and which is made to be punctured by an injection needle of a machine and which acts as the upper wall of the closed chamber.

  • the injection means are introduced into the capsule when a capsule holder with the capsule is inserted into the machine and the capsule is closed on the assembly for operation.
  • This type of machine is described, for example, in EP 1967099 B l.
  • the displacement that facilitates the crimping of the perforating elements with the aluminum foil to tear it and open the closed chamber depends on the increase of the internal hydraulic pressure.
  • the dynamics of this pressure increase depend on controllable factors, such as injection pressure, injection time or injection fluid temperature, which are usually constant values predefined by the machine or by the user.
  • this dynamic also depends on uncontrollable factors, such as the dynamics of the physical-chemical reactions of extraction or dissolution that produce a substance more or less concentrated depending on the characteristics of the ingredient, or the internal turbulent regime during injection. of fluid that depends on the shape of the capsule and the mode of impact of the injection jet, among other variables.

  • the nature of the uncontrollable factors makes the dynamics of the pressure increase and therefore of the opening of the closed chamber of the capsule different in each extraction process, causing several inconveniences that affect the quality of the final product.
  • This variability sometimes causes partial openings of the closed chamber due to the fact that the crimping of the sheet with the perforating elements fails locally, or that arbitrary openings occur, for example between two adjacent perforating elements.
  • a spray of fluid in the form of an aerosol can also be generated that suddenly comes out through the injection hole that is drilled in the upper layer of the capsule when the injection means are removed.
  • the expulsion of the leachate after extraction is generated mainly by the process of balancing between the internal pressure of the capsule and the external pressure, normally lower.
  • the dynamics of this pressure balance also depends on the shape and amount of passageways or tears that communicate the inside of the closed chamber with the outside. Therefore, a random opening of gaps can also result in the occurrence of a drip phenomenon that can be lengthened for minutes even after cessation of fluid injection in the capsule or in a sudden stream of fluid.
  • This process of expulsion of drink causes problems that have a negative impact on the cleanliness of the process and the user experience.
  • the proposals of the first type are based on the implementation of some type of valve system that restricts the passage of the beverage when the injection is finished and the hydraulic pressure inside the closed chamber is reduced.
  • EP 1864917 B 1 describes a type of capsules such as those mentioned above, which use closed chamber opening means integrated in the capsule itself and which are activated by increasing hydraulic pressure inside.
  • the valve provides valve means that block the flow to the outlet by cooperating a flexible lip with the housing wall.
  • the flexible lip is arranged in a disc located downstream of the chamber with ingredient that also has perforating elements that open the chamber closed with the ingredient when it swells.
  • the deformation of this lip also originates thanks to the effect of the internal hydraulic pressure and atmospheric pressure, which causes it to move away or close to the housing, allowing or restricting the passage of fluid.
  • the drawbacks of the operation of this valve system are very similar to those indicated for the opening of this type of capsules.
  • valve means The functioning of the valve means is dependent on the dynamics of internal pressure equilibrium and atmospheric, which makes it unpredictable.
  • opening of the chamber occurs late, even after the injection process is over, it can cause the internal pressure still retained to be released randomly and fluid is blown out, so that the valve does not It can regulate or contain.
  • WO 2008116818 Al an improvement of the previous valve technology is presented by introducing capillary holes in the opening means or valve insert, whose function is to release the pressure inside the closed chamber after injection or prevent the return of the upstream flow, so as to prevent its exit through the needle piercing hole and cross contamination. This is achieved with very small holes that are plugged after the injection restricting the passage and regulating the pressure equilibrium dynamics.
  • main problems referred to in the previous patent remain.
  • capillary holes The effectiveness of the capillary holes is very delicate since in turn their tamponade depends on the balance of internal and external pressures, which is little or not controllable, especially when the opening of the closed chamber is carried out by means of the internal hydraulic pressure.
  • materialization of capillary holes supposes a complex and high precision manufacturing process, which makes technology more expensive.
  • the proposals of the second type try to eliminate the jet of fluid that occurs when the residual pressure that remains after the injection of fluid is balanced with the outside.
  • the gas trapped in the fluid inside the capsule suddenly expands when the injection needle is removed and the passage that connects the inside of the closed chamber with the outside is opened. This causes the water under pressure to jet out of the capsule through the hole through which the injection needle, already removed, penetrated.
  • Another problem is the additional wear to which the injection needle is subjected, which must tear, pierce or penetrate an element of a material that offers greater resistance compared to a thinner or less stubborn layer.
  • This overexertion on the needle causes a problem of wear on the tip, which can affect, as already mentioned, the passage of fluid inside and the function of penetration and / or tearing in those capsules in which the Needle should penetrate the top sheet.
  • capsule housings are manufactured as a single piece using plastic molding techniques (such as PP) with the intention of providing a wall with insulating properties for the ingredient, and with sufficient mechanical capacity to serve as a container and support efforts during storage and extraction of the drink.
  • the shape of the housing normally corresponds to a molded plastic wall with smooth or faceted curves, such as a truncated cone or a cup-shaped piece. These types of shapes favor demolding and structural function.
  • the introduction of elastically deformable zones in the wall means that either new steps or manufacturing processes have to be incorporated to add or incorporate those zones, or that the molding or demolding process is hindered to the point where it is They must introduce new tools or tools to ensure continuity of production.
  • the housing is constructed based on high resilience materials, which penalize the manufacturing process, the cost of the product and the structural function (important during the storage phase), or additional structures are added, such as skeletons interiors, which help recovery, which also has the drawbacks indicated.
  • the introduction of elastically deformable areas in the wall of the housing means that the compression force to cause deformation has to be applied at the edge of the wall and run through the housing to the deformable zone.
  • this compression force is obtained from the closure of the machine on the capsule, and more specifically when the injection means press the capsule once introduced into the machine.
  • the injection means are closed on the capsule by a hinge movement
  • compression does not occur simultaneously on the entire edge of the wall, but the compression force travels along the edge as the injection means They close on the capsule.
  • This causes compression forces with horizontal component to appear and, therefore, that the deformation of the capsule is not uniform in one direction. An undesired displacement may therefore occur and that either the capsule does not regain its shape due to local plasticization effects, or that in the worst case the process of dispensing and removing the capsule is dangerous due to breakage, interruption of injection flow or clogging.
