Abstract:
A container system for a floral arrangement, comprising a waterproof container having a base portion which can act as a water reservoir, and a separate insert locatable from above into a lower part of the container, the insert acting to confine from above water within the reservoir, the insert carrying a porous water-retaining material lying within the reservoir, the porous material extending upwardly through the insert so that an upper portion of the material is exposed to receive the stems of cut flowers and the like.

Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to container systems for floral arrangements and more particularly to container systems for presenting cut flowers and the like in an attractive manner. 
     2. Description of the Prior Art 
     One previously proposed method of presenting cut flowers and the like involves the use of an open cell foam of relatively friable structure which can be easily pierced by the stem of a flower so that the flower stem is supported within the foam which also constitutes a reservoir for water, the foam standing within a shallow tray which constitutes a reservoir for further water and which also serves to carry a mesh-like support which retains the foam in position. Such a foam may be referred to as a florist&#39;s foam and one well known type of foam suitable for this purpose is sold under the trade mark “OASIS”. The assembly consisting of tray, foam, and mesh can be stood within an outer decorative container, for example of cardboard suitably shaped and decorated to form an attractive package. 
     One significant disadvantage with the system proposed above is that the trays are only able to hold a restricted volume of water and require frequent topping up. It is not practicable to increase the water holding capacity just by increasing the size of the tray as this, then, results in restrictions in the range of outer container sizes which can be used and also reduces the inherent versatility of the system. 
     SUMMARY OF THE INVENTION 
     According to the present invention, there is provided a container system for a floral arrangement, comprising a waterproof container having a base portion which can act as a water reservoir, and a separate insert locatable from above into a lower part of the container, said insert acting to confine from above water within the reservoir, said insert carrying a porous water-retaining material lying within the reservoir, said porous material extending upwardly through the insert so that an upper portion of the material is exposed to receive the stems of cut flowers and the like. 
     Advantageously the porous material consists of a block of a foam material of a type which is sufficiently friable that it can be pierced by the stems of cut flowers so that the stems are held by the foam material. 
     Preferably, the block of foam material is anchored within the insert so that the block is held firmly between the insert and the base of the outer container. 
     Advantageously the insert is configured to be a relatively tight sliding fit with the interior of the container so as to minimise the risk of leakage of water from the reservoir past the edges of the insert. Advantageously the insert is formed with one or more access ports, preferably adjacent the foam block, and through which the reservoir can be filled with water. 
     In one particularly preferred form of the invention, the container is of box-like form erected from a blank of board material, for example a cardboard material, made watertight by a waterproof liner applied to the interior surface of the container prior to, or during, installation of the insert. The insert may be formed from a waterproof or water-resistant material, for example a semi-rigid plastics sheet material capable of being cut and folded. Preferably, the insert is formed to provide tabs which may be bent to rigidify the sheet and also, possibly, engage the base of the container to support the insert therefrom.

     DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     As shown in the accompanying drawings a container system in accordance with a preferred embodiment of the present invention comprises an outer container  2  preferably of box-like form erected from a blank of suitable material, for example of corrugated or other board. The interior of the box  2  is made watertight using a liner  4  of a thin waterproof plastics sheet, for example of polyethylene or polypropylene which is retained within the box  2  by an insert  6  which carries a foam block  8  for cut flowers. The insert  6  is pushed downwardly into the box  2  from above onto the sheet of plastics film forming the liner  4  so that the liner  4  is moved onto the bottom of the box  2  and held in shape by the insert  6 . As shown, the insert  6  is formed from a sheet of waterproof or water-resistant material which can be cut and folded to a required shape. In one preferred form, the insert  6  is fabricated from an extruded plastics sheet material of semi-rigid form comprising opposed outer layers interconnected by a series of spaced parallel webs as manufactured and sold under the trade mark “COREFLUTE”. The edges of the insert  6  are formed with two sets of opposed tabs  6   a ,  6   b . One set of tabs  6   a  is folded upwardly from the plane of the insert  6  and act to rigidify the insert against bending deflection and the other pair of tabs  6   b  is folded downwardly to form legs by which the insert  6  is supported from the bottom of the box  2  and further rigidify the insert  6  against bending deflection. In an alternative form, both sets of tabs  6   a ,  6   b  may be folded upwardly or downwardly. 
     The central part of the insert  6  is formed with an aperture for receiving the block  8  of florists foam such as that sold under the trade mark “OASIS”. The block foam  8  projects to the bottom of the box  2  and extends upwardly through the insert  6  to form above the insert an exposed portion for receiving the stems of cut flowers and the like. The foam block  8  is retained within the insert  6  by means of a support  10 , for example consisting of a flexible plastics mesh, which fits within the aperture in the insert  6  and surrounds the upper exposed part of the block  8  while still permitting access through the mesh for the flower stems. Preferably, the block  8  is a relatively tight fit within the aperture in the insert  6  and thereby retains the mesh support  10  within the aperture with a lower edge lO a  of the mesh support  10  being trapped beneath the edge of the aperture as shown in FIG.  2 . 
     In order to assemble the container system just described, the outer box  2  is first erected from the blank. Plastics film for forming the internal liner  4  is then cut approximately to size. The foam block  8  is pre-saturated with water and is mounted within the insert  6  in which it is held in place by the mesh support  10 . The liner  4  is placed over the top of the box  2  and the insert  6  carrying the saturated foam block  8  is moved downwardly into the box  2  thereby pushing the liner  4  into the box. The insert  6  is shaped to be a relatively tight fit within the interior of the box so that frictional pressure between the edges of the insert  6  and the inner surface of the box  2  is sufficient to hold the bottom of the foam block  8  firmly against the bottom of the box  2 , with the foam block effectively being wedged between the bottom of the box  2  and the mesh support  10  which encloses the upper part of the foam block  8 . The relatively tight fit between the insert  6  and box  2  also acts to resist escape of water from the bottom part of the box  2  beneath the insert  6  whereby the system is less susceptible to spillage. The aperture within the central part of the insert  6  and which receives the upper part of the foam block  8  is also shaped to form one or more access ports  12  (see FIG. 1) outside of the periphery of the block  8  and through which water can be poured into the bottom part of the box  2 . When the insert  6  with the foam block  8  has been inserted into position in the lower part of the box  2 , water possibly treated with product to increase the life of the cut flowers, is poured into the bottom part of the box  2  through the access ports  12  provided in the insert  6  around the foam block  8 . The bottom part of the box  2  then acts as a relatively large capacity reservoir  14  which can contain sufficient water to last for the life of the flowers. As mentioned previously, due to the relatively tight fit between the insert  6  and inner wall of the box  2 , the system is not susceptible to spillage of water from the reservoir  14 , for example during transportation from the florist to the customer. Likewise, the positioning of the access ports  12  within the central part of the insert  6  adjacent the foam block  8  will minimise the risk of spillage occurring through these ports. 
     Instead of forming the liner  4  from a plastics sheet, the liner  4  can consist of a thin waterproof plastics bag. 
     In an alternative form of insert shown in FIG. 3, the aperture  20  within the insert for receiving the foam block is bounded on two opposed sides by downwardly inclined flaps  22  with serrations  22   a  along their inner edges to bite into the foam block whereby to grip the block and thereby to prevent upwards movement of the block within the insert, thus obviating the need for the mesh support. This type of insert is particularly suitable for use with foam blocks of a structure which renders the block relatively coherent and not readily friable at the edges. However, for blocks of a structure which renders their edges rather more friable, the first form of insert with the mesh support would be preferred. In this alternative form of insert, the downwardly inclined flaps  22  with serrations at their inner edges also act as ducts for feeding water into the reservoir in the bottom part of the box beneath the insert, the serrations  22   a  defining a series of small ports to facilitate passage of the water past the inner edge of each flap  22  The insert shown in FIG. 3 is produced from a blank as shown in FIG. 4 from which it will be seen that in addition to the opposed flaps  22  bounding one pair of opposed sides of the aperture  20 , the aperture  20  is bounded at its other pair of opposite sides by flaps  24  which are folded downwardly to lie against the adjacent sides of the block whereby the block is firmly seated and retained within the insert. 
     Although it is preferred to form the outer container of the system in the form of a box of cardboard or the like which is then made waterproof by an applied lining, as cardboard as boxes can be easily produced in the form of blanks of sheet material which can easily be printed with suitable exterior designs and colours and can readily be stored in blank form, alternatively the outer container could be in the form of a preformed watertight container, for example of a suitable plastics material. The insert  6  may also be pre-formed in a rigid plastics material. 
     The embodiment has been described by way of example only and modifications are possible within the scope of the invention.
