Definitions

  • the present invention relates to a pack for, and a method of packaging, a two-component product, such as an adhesive formed from an epoxy resin and a hardener.
  • epoxy adhesives have been sold with the resin and the hardener packaged in separate tubes, so that the resin and the hardener do not react before the product is to be used.
  • the user dispenses equal amounts of the resin and hardener from the respective tubes and mixes the two components with an appropriate implement to form the adhesive.
  • the mixing process is often messy and requires the provision of a mixing implement and mixing surface or container by the user.
  • a pack for a two-component product primarily a pharmaceutical product
  • This pack comprises two stacked compartments for the respective products separated by a barrier layer which can be ruptured by an internal projection when it is desired to mix the components. Mixing of the components is carried out by the user shaking or kneading the pack. It is apparent that the compartments of the pack of GB-A-2002316 cannot both be filled in a single operation, which leads to a complex assembly process for this type of pack.
  • EP-A-612673 and EP-A-688726 each disclose packs for a multi-component product in the form of a bag composed of bonded plastics sheets.
  • the arrangement of the sheets divides the interior of the bag into compartments for respective components of the product. Perforations are provided in the sheets separating two compartments, which perforations are ruptured when it is desired to mix the components. Mixing of the components is achieved by the user kneading the bag.
  • This type of pack requires a complex filling process, as the compartments for the components are only formed when the sheets have been bonded together.
  • the invention provides a pack for a two-component product, such as for example an adhesive formed from an epoxy resin and a hardener, the pack comprising an enclosure member having defined therein two adjacent compartments for respective components of the product, and a substantially planar base member bonded to the enclosure member so as to close each compartment, wherein a rupturable portion is provided between the two compartments at the interface of the enclosure member and the base member, and wherein the rupturable portion is arranged to be ruptured, in use, to bring the two compartments into communication and allow the components of the product to be mixed within an envelope formed by the communicating compartments .
  • a two-component product such as for example an adhesive formed from an epoxy resin and a hardener
  • the invention provides a pack in which the two components of the product are separated during storage, but can be mixed, for example by kneading, without opening the pack. This prevents the need for the user to provide a mixing implement and/or mixing surface or container and reduces the messiness of the mixing operation. Furthermore, it is possible for the mixed product to be dispensed straight from the pack.
  • the pack according to the invention is of a particularly convenient design in that it is possible for the compartments in the enclosure member, which may be in the form of recesses, wells or blisters, to be filled in one operation and then closed by bonding the base member to the enclosure member. This allows for greater flexibility in the packaging process than has previously been available.
  • the invention provides a method of packaging a two-component product, the method comprising: providing an enclosure member having defined therein two compartments; filling each of said compartments with a respective component of the product ; bonding a substantially planar base member to the enclosure member so as to close each filled compartment; and providing a rupturable portion between the two compartments at the interface of the enclosure member and the base member, which rupturable portion is arranged to be ruptured, in use, to bring the two compartments into communication and allow the components of the product to be mixed within an envelope formed by the communicating compartments.
  • the base member may conveniently provide a lid for the two compartments after filling.
  • the rupturable portion may be in the form of a rupturable bonded region between the compartments, for example, a relatively narrow region.
  • the rupture of the bond can provide a path between the adjacent compartments, there being no need to provide perforations or breakage regions in the material of the enclosure member or that of the base member. This simplifies manufacture.
  • the rupturable portion is rupturable by external pressure applied to either one of the compartments by the finger and thumb of a user, and this may determine the dimensions of such a bonded region.
  • the rupturable portion may be in the form of a weakened or weaker bond between the enclosure member and the base member.
  • a sealing bond will be formed by the base member all the way round its interface with each compartment, with a weakened area between the two compartments providing the rupturable portion.
  • the rupturable portion is provided with an interference layer, such as latex based ink applied to the appropriate portion of the enclosure member or the base member, at the interface of the base member and the enclosure member.
  • the enclosure member may be relatively rigid, at least in part, although it is desirable for the portions of the enclosure member defining the compartments to be relatively flexible so that the components can be manually manipulated during mixing. Indeed, the entire enclosure member may be made from a relatively flexible material .
  • the enclosure member may be in any suitable form.
  • the enclosure member is made of moulded plastics.
  • the enclosure member is in the form of a thermoplastic, for example polypropylene, forming, such as a vacuum forming.
  • the base member may be relatively rigid or relatively flexible. For example, if it is desired for the pack to be relatively rigid, the rigidity may be provided by the enclosure member, the base member or both.
  • the base member may be made from any suitable material, for example plastics.
  • the base member is made of a laminate, for example in the form of a metallised plastics foil .
  • a plurality of packs sharing a common base member may be provided.
  • Such a plural pack unit may include packs with differently sized compartments or packs with different fill volumes or packs for different products, e.g. different cure time adhesives.
  • the material of the base member and/or the enclosure member may be provided from a continuous supply, for example a reel, of material.
  • packs according to the invention may be made on a continuous production line.
  • a plurality of packs may be made, and optionally filled, simultaneously.
  • the resulting plural pack unit may be in strip form.
  • the manufacturing or filling process may include the forming of the compartments in the enclosure member.
  • the enclosure member and the base member may be bonded to each other in any suitable manner, for example by thermal or ultrasonic welding or by the use of an adhesive.
  • the pack may be opened to release the mixed product by puncturing or cutting the envelope formed by the communicating compartments.
  • an outlet or nozzle is provided through which the product may exit the pack.
  • the nozzle may be provided with a closure.
  • the closure may be re-usable, for example in the form of a cap.
  • a product such as an epoxy adhesive
  • the product must be used shortly after the components have been mixed, and thus a re-usable closure is not required.
  • a blind duct is provided, for example as part of the enclosure member, in communication with one of the compartments.
  • the closed end of the duct may be cut, twisted, broken or otherwise separated from the pack to provide an outlet, e.g. a nozzle, from which the mixed product may be dispensed.
  • the duct has a weakened portion to aid the removal of the end of the duct.
  • the duct is connected to an extended portion of the pack which the user may grip when removing the end of the duct and which may be removed with the duc .
  • Figure la shows a perspective view and figure lb shows a plan view of a pack according to an embodiment of the invention
  • FIGS. 2a to 2c illustrate the operation of the pack of figure 1;
  • Figure 3 shows the pack of figure 1 in use .
  • a pack for an epoxy adhesive and a hardener comprises an enclosure member in the form of a polypropylene vacuum thermoforming 2.
  • the thermoforming 2 includes two depressions each defining a compartment 4,6 for the epoxy adhesive and the hardener respectively.
  • a part of the thermoforming 2 is in the form of a blind duct 8 extending from the compartment 6 and in communication therewith.
  • a twist-off panel 10 extends from either side of the duct 8 and enables the end of the duct 8 to be twisted from the thermoforming 2, so that the contents of compartment 6 can exit through the nozzle formed by the residual portion of the duct 8.
  • the compartments 4,6, duct 8 and twist-off panel are all formed integrally as parts of the thermoforming 2.
  • a base member in the form of a sheet of metallised polypropylene laminate corresponding in size and shape to the outline of the thermoforming 2 is bonded to the lower surface of the thermoforming 2.
  • the laminate closes off and seals the compartments 4,6. Between the positions of the compartments 4,6 on the laminate an interference coating of latex based ink is provided which interferes with the bond between the thermoforming 2 and the laminate to provide a rupturable portion 12.
  • the epoxy adhesive and the hardener are deposited in their respective compartments 4 , 6 in the thermoforming 2.
  • the laminate, which has the interference coating printed thereon, is then bonded to the thermoforming to close the compartments, i.e. to form a lid.
  • the mixing operation is carried out while the epoxy adhesive and hardener are still completely contained within the pack.
  • the twist-off panel 10 is rotated to break off the end of the duct 8, so that the residual portion of the duct 8 forms a dispensing nozzle.
  • the mixed adhesive can then be dispensed through the nozzle/duct 8 by applying pressure to the envelope formed by the communicating compartments 4,6. This is shown in figure 3.
  • the invention has been described herein with particular reference to epoxy adhesives, it will be appreciated that the invention may be applied to other two-component products, such as pharmaceutical preparations, toothpastes and the like.
  • the invention is also of application to products comprising more than two components, with a compartment being provided for each component.
  • the invention may be applied to products wherein not all components are in a fluid phase, for example products comprising a liquid component and a solid component, two solid components or even one or more gaseous components.

Abstract

Cet emballage pour résine époxy et durcisseur est constitué d'un thermoformage (2) à deux alvéoles adjacentes (4, 6), l'une pour la résine époxy, l'autre pour le durcisseur. Une feuille laminée est solidarisée à la face inférieure du thermoformage (2) de façon à fermer chacune des alvéoles (4, 6). L'interface du thermoformage (2) avec le laminé présente entre les deux alvéoles une zone de faiblesse (12) qui cède lorsqu'on applique une pression extérieure sur l'une des alvéoles (4, 6). Cette rupture met en communication les deux alvéoles (4, 6), ce qui permet le mélange de la résine avec le durcisseur dans une enveloppe close. Pour déposer la colle mélangée on utilise une buse formée par un conduit autocassant (8) communiquant avec l'une des alvéoles (4, 6).
