Definitions

  • the invention concerns a method and apparatus and a unit produced by the same.
  • the unit may take a number of forms, for example it may include one or more containers for emanation of volatile substances, e.g. insecticides, or it may be a packaging unit for one or more candles.
  • DE-A-44 46 413 describes a container for an active substance, such as perfume, insecticide or the like, including a portion of sheet material drawn to provide a larger cavity and a smaller cavity, closed by respective closing layers. Between the above-mentioned cavities a wick extends, which is covered by the closing layers.
  • the cavity in which the active substance and a portion of the wick are contained is closed by a permanent closing layer, while the other cavity, wherein the other end of the wick extends, is closed by a removable layer.
  • the wick is uncovered by removal of the removable layer and the wall of the corresponding cavity is turned away from the wick in such a way that it may be brought up to a heater of an evaporator device to facilitate the emanation of the active substance. Turning the cavity wall away from the wick means that the user, after removal of the removable layer, sets the cavity wall at an angle to the position which it had originally.
  • the container is obtained by drawing a first sheet of plastic material to form a cavity having an edge flange, extending outward and crossed by the wick, whereon a closing and substantially plane second sheet is welded, or glued.
  • DE-U- 296 12 562 also describes a package for containing the container mentioned above, which has a first packaging sheet element wherein a cavity is formed, which has substantially the same shape as the container and a second packaging sheet element, which is substantially plane and is attached, in a removable way, to the first packaging element.
  • the cavity has an extension to lodge the end of the wick pro ecting from the container, holds the container when the latter is placed inside the cavity and has a plurality of seating projections which support the container flange inside the cavity.
  • the container is removed from the package, after removing therefrom the removable sheet, and inserted into an evaporator device wherein a heater acts to facilitate the evaporation of the volatile substance.
  • a heater acts to facilitate the evaporation of the volatile substance.
  • Candles are normally manufactured as such and then put into boxes each containing one or more candles. Candles are sold m that way to customers.
  • each candle includes a metal anchorage from which a wick extends upwardly. After the wick has been lit, the consumer pours candle wax in granules into the bowl in order to prevent the candle from being consumed rapidly.
  • a further drawback is that, when the packaging units are stocked for a long period, a somewhat significant proportion of perfumes which are included in the wax is lost to the ambient at posphere.
  • blow-thermoforming packaging systems a flowable product is filled into containers which have been blow- thermoformed from face-to-face thermoplastic strips and which, after filling, are then sealed for delivery to customers.
  • the content of each blow- thermoformed packaging unit is only formed of a single flowable product.
  • US-A-5, 121, 835 discloses a candle display package including two transparent panels which double as a mould and as a container for the candle (s) .
  • One or each of the panels is a mould panel having one or more shaped recesses with one or more sprue passages.
  • Wick holders, including V-shaped notches, are provided beyond opposite ends of the or each recess.
  • the panels may be held together during moulding and thereafter by snap-fastener-type elements formed on the panels.
  • a display graphics card may be held between the panels.
  • the panels are hinged together beyond the upper ends of a group of candle recesses, with the panels held together with the hinge lowermost and the sprue passages uppermost, and wax is poured in through the passages and allowed to set.
  • a method including forming a container utilizing first and second strips of material, said forming comprising blow-thermoforming, characterized in that a wick is located to extend between said strips and through the interior of said container.
  • apparatus including forming means which utilizes first and second strips of material in forming a container, said forming means comprising blow- thermoforming means, characterized in that locating means serves to locate a wick to extend between said strips and through the interior of said container.
  • a unit comprising a container which has been formed by utilizing first and second strips of material in blow-thermoforming, characterized in that a wick extends between said strips and through the interior of said container and that said container contains a substance which, in a liquid state, flows along said wick. Owing to these aspects of the invention, it is possible to produce wicked units relatively rapidly and relatively cheaply.
  • a method including forming a container utilizing first and second strips of material, filling said container with a substance and locating a wick between said strips to extend through said container, whereby said substance, in a liquid state, flows along said wick, characterized in that said wick is introduced to between said strips before said substance is filled into said container.
  • a method including utilizing first and second strips of material to form a container, filling said container with a substance and locating a wick between said strips to extend through said containers, whereby said substance, in a liquid state, flows along said wick, said container being part of a unit m which said wick is completely enclosed, characterized in that no more strips than said first and second strips are employed m providing the external walls of said completed unit.
  • a unit comprising a container comprised of first and second strips of material, a substance contained by said container, and a wick extending between said strips and through said container, whereby said substance, m a liquid state, flows along said wick, said wick being completely enclosed m said unit, characterized m that no more strips than said first and second strips are employed in providing the external walls of said unit.
  • a method comprising providing candle wax means and wick means m a container formed of first and second walls joined together, characterized by injecting anchoring means into said container.
  • apparatus comprising providing means arranged to provide candle wax means and wick means in a container, and forming means arranged to form said container of first and second walls joined together, characterized m that injection means is arranged to inject fluid anchoring means into said container.
  • a unit comprising candle wax means and wick means m a container formed of first and second walls joined together, characterized by anchoring means m said container.
  • a method comprising introducing a fluid anchoring substance into moulding means having walls defining an interior thereof, said anchoring substance flowing to a bottom part of said interior to an anchorage location at which said anchoring substance forms an anchorage means which causes a wick to be anchored at said anchorage location upon setting of said anchoring substance, and introducing fluid wax to above said anchorage means and around said wick between said wick and said walls.
  • a method comprising providing candle wax means and wick means m a container formed of first and second walls joined together, characterized by introducing said wick means through an opening of said container. Owing to this aspect of the invention, it is possible to provide a wicked container m an efficient manner. According to a twelfth aspect of the invention, there is provided a method wherein a distribution container is formed of first and second walls joined together along an outline of said container and first and second flowable products are filled into said container.
  • apparatus comprising means arranged to form a distribution container of first and second walls joined together along an outline of said container and to fill said container with first and second flowable products.
  • a unit comprising a distribution container formed of first and second walls joined together along an outline of said container and first and second flowable products in said container.
  • the unit comprises a container having a cavity containing a volatile substance, a wick extending outwardly from said cavity and intended to transfer, in a controlled manner, the volatile substance from the cavity to the ambient atmosphere, the cavity being provided with an extension projecting outwards and bounded by at least one element of removable sheet material containing the outer end zone of the wick.
  • the container is obtained by thermowelding of two strips of gas-barrier sheet material along a welding edge, the appendix forming an outward extension of that edge, and thermoforming at least one of the strips to make it concave and joined; between the strips there is interposed the wick, which is preferably flat.
  • the appendix has a gap which exposes the outer end zone of the wick, and the gap is covered by a fluid-tight removable cover.
  • the appendix may be covered, at both its sides, by sheets of removable material, for example a peelable material which cover gaps at both sides, and thus protects the wick and isolates it from the outside environment and thereby prevents the emanation of the active substance before the opening of the unit.
  • the unit is totally closed without it having to be introduced into a package. Moreover opening is simplified because, for use, it is sufficient to remove the sheets of removable material, freeing the wick.
  • the wick is attached to the appendix along at least one pair of edges.
  • a pair of strips is thermowelded and at least one strip of the pair is thermoformed to obtain groups of containers joined by thermowelding along respective major peripheral edge zones of the containers, each container having a non-welded peripheral edge zone providing a communication between the container interior and the outside.
  • the method then includes filling with the substance (s) , inserting wicks through the communications into the container interiors, and closing the containers; wherein, during the closing, the wick is enclosed between the strips.
  • a portion of the or each communication conduit is punched out, m such a way that during closing of the container (s) the outer end zone (s) of the w ⁇ ck(s) stay(s), at least partially, not engaged by the strips.
  • the appendix defines a chamber m which the outer end zone of the wick is contained, the chamber being openable along a predetermined fracture line interposed between an edge zone of the chamber and the container interior.
  • a packaging unit comprising a container, and a candle m said container having wick means, said container comprising first and second walls joined together and extending over respective opposite sides of the candle.
  • a method comprising providing distribution containers with respective wick means extending therethrough, introducing fluid wax to between the wick means and the respective containers and subsequently delivering to customers packaging units formed of solidified wax obtained from the fluid wax, the wick means and the containers.

  • Each zone 14 has an upper end portion defining an opening in the form of a conduit 15 which allows communication between the cavity 13 and the outside .
  • a pair of opposite punches (5') is driven to act on corresponding zones of the strip portions 11 and 12 defining each conduit 15, so as to create therein a pair of opposite window-shaped gaps 16, having substantially the same dimensions as and aligned with each other; the pair of gaps 16 has a transverse dimension less than the transverse dimension of each conduit 15.
  • the cavities 13 are filled with a liquid, active substance 18, which is introduced into the cavities through filling cannulae 17 inserted through the conduits 15.
  • each conduit 15 extends vertically, so as to act as a passage for the corresponding cannula 17 (as well as for the wick 19, as will be explained below) and assure an optimal condition of filling of the corresponding cavity 13.
  • each group 4 is advanced to the introducing station 7, shown m Figure 4, for inserting a wick 19 into the cavity 13 through the conduit 15.
  • the wick 19 is obtained by unwinding of a porous wick stock 22, such as paper or a textile, permeable to the liquid substance 18, from a reel 20 and cutting thereof by shears 21 which are above the conduit 15.

  • the wicks are inserted through the respective conduits 15 by an inserting device, after they have been cut and stored m a suitable loader supported above each conduit 15.
  • FIGs 8 and 9 show that, at the closing station 8 for closing groups 4, each conduit 15 is squashed so as to extend the welding zone 14 between the portions 11 and 12 and isolate the cavity 13 from direct communication with the outside. Owing to the squashing of each conduit 15, the wick 19 is gripped between the portions 11 and 12. The wick projects outwards with respect to the cavity 13 through a portion 25 of the periphery of the cavity 13. The gaps 16 are smaller than the dimensions of the wick and therefore, during squashing of the conduit 15, they frame the outer end zone 26 of the wick which projects from the cavity 13, the zone 26 thus being held firmly round its periphery by the edges of the openings 16. The gripping of the zone 26 assures stable positioning of the wick 19 inside the cavity 13.
  • the communication with the outside may take place only through the wick zone 26. Therefore, the liquid, volatile, active substance 18 tends to move from the cavity 13, wherein it is contained, to the exposed zone 26 while the substance evaporates, for example if it is heated in an evaporating device of conventional type.
