Definitions

  • the invention relates to a container for a multi-component reaction and a method for filling such a container according to the preambles of claims 1 and 22 respectively.
  • Containers for multi-component reactions are known and are used, for example, in so-called pocket warmers or glow sticks.
  • these containers comprise at least two chemical chambers which are broken open in use so that reaction components contained in them can interact with one another. This interaction - usually a chemical or physical reaction - either adds or removes heat from the environment.
  • Another result of this interaction can also be the generation of light or sound.
  • the container itself is opened so far that either the reaction components themselves or the reaction product resulting from them can be used again. This is the case, for example, with multi-component adhesives.
  • the aforementioned pocket warmers or light sticks represent a further variant, in which the container containing the reaction components remains intact even after the chemical chambers have been broken open.
  • such containers are manufactured or filled in such a way that the container as a whole is completed to such an extent that the chemical chambers are filled from a remaining open side seam that is later to be sealed, the respective reaction component in FIG the tube-like chamber of the container provided for this purpose is filled. The sealed seam is then closed.
  • the container itself is formed by two sheet-like foils or similar sheet-like bodies which are sealed to one another at least in sections.
  • this filling method also affects the geometry of the container, which is formed unevenly, since the substances inevitably cause thickening on the lower side of the container, whereas the reaction chambers on its upper filling side remain virtually empty even after filling.
  • Another disadvantage of this filling variant is that the filling must take place across the area of a subsequent sealing seam. There is a risk that the areas to be sealed later will be contaminated with the solid or liquid reaction component which is filled into the respective chambers, which without one an additional cleaning step with the associated risk of contamination of the reaction components leads to a weakened and potentially leaky sealing seam.
  • Another object of the invention is to fill such a container.
  • the object is achieved by a container for a multi-component reaction with at least two chemical chambers and at least one mixing volume, the container being formed from a bottom film provided with depressions and a possibly structured top film, the top film being connected, in particular sealed, to the bottom film at least in sections is.
  • the bottom film is provided with depressions into which a desired reaction component can be conveniently filled. Since the bottom film extends horizontally, the depressions are essentially trough-shaped and / or cup-shaped and in turn extend essentially perpendicular to the bottom surface. In the absence of the possibly structured upper film, the depressions are therefore freely accessible from above for a filling process, so that the filling process can be carried out as a horizontal process.
  • the top film is connected to the bottom film at least in sections, with sealing or adhesive bonding of the two films being a preferred type of connection.
  • the seal runs in such a way that the depressions provided in the base film, which represent the chemical chambers, are separated from one another in such a way that premature mixing of the reaction components which are arranged in the chemical chambers is not possible. Such mixing can only take place when the seal separating the chambers is broken and a mixing volume is made available for the reaction components.
  • the reaction components can also be brought into contact with one another via valves which are arranged between the chemical chambers and which can be closed again if necessary. This is advantageous, for example, if, in the case of a heat-generating reaction, uniform and permanent heating is to be brought about without undesired sudden heating occurring.
  • the reaction can be controlled by means of a valve-like passage from chamber to chamber and the reaction can also be stopped if necessary.
  • the base film is embossed and / or deep-drawn and / or folded, so as to produce the depressions in the base film.
  • the top film can be designed analogously. This is particularly advantageous if the structuring of the top film corresponds to the structuring of the bottom film and if the multi-component reaction taking place in the container is accompanied by an increase in volume.
  • Both the top film and the bottom film can be produced from a preferably cold-formable plastic film and / or such a laminate, a plastic or aluminum laminate having a high strength being preferred.
  • the top film preferably has a material with high thermal conductivity, such as a metal, preferably aluminum. In this way, in the case of a heat-emitting or heat-absorbing reaction, a good heat transfer between the interior of the container and the environment is possible, so that the container as a heating or Cooling container is usable.
  • the base film is also provided with a corresponding material with high thermal conductivity.
  • the material with high thermal conductivity can be embedded in a laminate or, for example, as the sole metal foil per se.
  • the base film is made of a foamed material and in particular has polyethylene and / or polypropylene and / or polyethylene terephthalate and / or mixtures thereof.
  • the bottom foU serve as an insulating bottom, while a drink or meal, for example, is warmed or kept warm on the top of the container.
  • the bottom surface serves to prevent heat being released downwards
  • the upper surface which is made from a material with high thermal conductivity, serves to deliver the heat as effectively as possible to the object placed on the container.
  • the base film has a metallic, preferably reflective layer, in particular in the form of a metal covering.
  • this layer is applied on the inside of the bottom sheet, that is to say on the side of the bottom sheet facing the interior of the container, and preferably consists of aluminum. This can be vapor-deposited or applied in the form of a FoHe to the bottom film or to the laminate forming the bottom film.
  • such a metal lining can be used both on the inside and on the outside of the container
  • the bottom foil and / or the upper foil has at least one barrier layer, the ethyl vinyl alcohol (EVOH), quartz (Si0 2 ) and / or aluminum, in particular in the form of a foHe or a deposited one
  • EVOH ethyl vinyl alcohol
  • quartz Si0 2
  • aluminum in particular in the form of a foHe or a deposited one
  • Such a barrier layer ensures that the container according to the invention becomes insensitive to permeation and / or diffusion of substances into or out of the container.
  • the container can be selectively permeable to certain substances if desired.
  • a selective permeation is advantageous, for example, if a pressure equalization with the environment is to be achieved in order to prevent the container from bursting or being bombed.
  • the individual chambers of the container are separated from one another by means of a strip seal and / or by means of a point seal and / or on account of an applied negative pressure, in particular a vacuum, which brings about sealing contact between the bottom film and the top film.
  • the seals mentioned can be in the form of weakened seals with breakage units, in order in this way to ensure that the individual chemical chambers are connected to one another to define a mixed volume, destruction of the container being avoided by breaking an outer sealing seam.
  • At least one chamber according to the invention has a SoHbruchsteUe, in particular in the form of an inner sealing tip, so that starting from this chamber below
  • Application of pressure forms a mixed volume, which is formed from the volume of at least one adjacent chamber and the chamber having the inner tip.
  • the mixing volume in turn forms a reaction chamber in which the reaction of the reaction components takes place.
  • opening the predetermined breaking point or the inner sealing tip causes a reaction component that is in an adjacent chamber without or with a lower vacuum to suddenly enter the evacuated chamber spreads and triggers a very fast, possibly explosive subsequent reaction.
  • the spreading and mixing of reaction components is advantageously supported by suction-induced suction of components from neighboring chambers, which contributes to a quick and complete reaction.
  • at least one actuatable opening device or aid is provided, which can be designed, for example, as a mandrel or KHnge to create a connection between adjacent chambers, so that a mixed volume is formed.
  • the opening device is advantageously secured against unintentional actuation, so that the establishment of an unwanted fluid connection between the respective chambers is avoided.
  • the actuatable opening device By means of the actuatable opening device, it is possible to pierce the sealing seams separating the chambers between the bottom and the upper surface, the bottom and the upper surface being pushed apart and the sealing being released. Care must be taken to ensure that the bottom or upper surface is never pierced when the seal is separated.
  • a reinforcement can be provided in the area of the opening control or aid, by means of which damage to the bottom and top films is avoided.
  • a flat, for example spatula-shaped design of the opening device is also helpful in accordance with the design of the sealing seams.
  • a control system in the form of channels, webs and / or a preferably structured, in particular perforated, distribution body is also provided, along which the reaction components can spread and distribute.
  • a control system can be produced, for example, by applying a vacuum to the container starting from a chamber, which preferably contains a liquid medium, during the sealing of the container, so that the air is sucked out of the container.
  • folds are formed in particular in the upper surface, the inner sides of which, due to the vacuum, are tightly sealed to one another, but which, when a chamber is broken open, can separate from one another and act as a channel-like distribution system.
  • This formation of folds during the application of a vacuum is desirable in accordance with one aspect of the invention and can be supported, for example, by selecting the size of the top film to be somewhat larger than is absolutely necessary to cover the bottom surface.
  • Another possibility of making a channel-like control system available is to make a dedicated choice in the formation of weakened sealed seams, which preferably break open. Such sealing seams can for example be thinner or less sealed than. adjacent fixed sealing seams.
  • solid webs or channels can also be incorporated into the container according to the invention, along which the distribution of a liquid or pasty reaction component takes place.
  • a film-like distribution body can be provided, which establishes a connection between the reaction chambers as a foam or hose. According to a film-like configuration, this distribution film body can be arranged and perforated above the reaction chambers.
  • a liquid reaction component which in turn is provided above the distribution film body and is released to initiate the multicomponent reaction, accordingly distributes above the distribution film body quickly and uniformly and passes through the perforations of the distribution film body with further reaction components provided in the chambers of the container according to the invention in contact. According to a further embodiment, it is possible to pass a liquid reaction component through a tubular distribution system to the respective chambers which contain further reaction components.
  • the container has at least one expansion device in order to prevent the container from bursting or bulging.
  • the expansion device preferably comprises at least one area separated from the mixing volume, preferably by a sealed seam. This area can be designed in the form of separate, sealed corners.
  • this expansion device can compensate for pressure, with a sealing seam between a mixing volume and the separated area first being opened in a first step.
  • the opening can be brought about by a sealing seam of defined thickness and possibly with the aid of an inner sealing tip, the opening pressure causing the sealing coming from inside the container containing the reaction components.
