Abstract

A sponge is compressed and sealed within a air-tight enclosure to provide a compact product and to provide ready identification that the seal has been broken to indicate a possible contamination of the sponge. The enclosure may be formed by two plastics sheets welded together by ultrasonic means whilst a sponge is held compressed between the sheets. In a preliminary station, a line of weakening 22 is formed in one of the sheets at the same time as a tag 23 is welded to the sheet by shaped ultrasonic welding horn 35. <IMAGE>

Description

Method of Packaging A Sponge This invention relates to a method of packaging a sponge and to a sponge so packaged.
Sponges are being provided more often by hotels for their guests and people are beginning to use and accept sponges for washing themselves as well as general cleaning tasks. Sponges for human application generally are softer than household sponges but the method of the invention is applicable to all types of sponges.
For hotel use, guests prefer to use sponges or other washing implements such as brushes and face washers which they know are clean, sterile, unused and/or at least have not been tampered with. Until now it has been difficult to determine if a sponge has been used or tampered with. Also, the packaging of sponges for storage and transport has caused problems as they contain a large proportion of empty space and thus although light, each sponge occupies a relatively large volume. This volume could be substantially reduced if the sponges, which are readily compressable, could be packaged in the compressed state.
Accordingly, the present invention provides a method of packaging a sponge comprising the steps of compressing the sponge to expell air from within the sponge and enclosing the compressed sponge within an air-tight enclosure to substantially maintain the sponge in the compressed state.
Preferably, the air-tight enclosure is an envelope made from a plastics material such as PVC or from a metallic paper material.
Preferably, the sponge is compressed between two sheets of plastics or metallic paper material and the two sheets are sealingly joined to form the envelope, for example, by heat or ultra-sonic welding.
Alternatively, the sponge is compressed between a folded sheet of plastics or metallic paper material and the edges are sealingly joined to form the envelope.
Preferably, the method includes the step of forming a zone of weakness on a first side of the envelope or on one side of the folded sheet.
Preferably, the zone of weakness defines a substantially U-shaped region.
Preferably, the method includes the step of attaching a tag to the first side of the envelope adjacent the zone of weakness.
Preferably, the tag is attached to the envelope and the zone of weakness is formed by ultra-sonic welding.
Preferably, the method includes the step of printing indicia on the inside surface of the second side of the envelope.
In a second aspect the invention provides a packaged sponge comprising a sponge compressed to substantially remove air therefrom and enclosed within a sealed enclosure to substantially maintain the sponge in the compressed state.
Preferably the sealed enclosure is a metallic paper or plastics material envelope.
One preferred embodiment of the invention will now be described by way of example only with reference to the accompanying drawings in which: Figure 1 depicts a sponge packaged according to the preferred embodiment of the present invention; Figure 2 illustrates how the sponge is removed from the package; Figure 3 illustrates an exploded view of the preferred embodiment; Figure 4 illustrates a machine used to prepare the packaged sponge of figure 1; and Figure 5 illustrates a portion of the machine of figure 4.
As shown in Figures 1, 2 and 3 the preferred embodiment of the packaged sponge 10 is a substantially flat rectangular article. The final shape of the packaged sponge will depend on the shape of the sponge to be packaged and its density. For the purpose of illustration a rectangular body sponge will be used. Of course, in practice, the sponge may be any shape or size.
The packaged sponge 10 has a sponge 11 contained within an enclosure or envelope 20. The envelope is made from two sheets of clear PVC plastics material 21, 24 between which the sponge 11 is sandwiched.
Other suitable material, such as metallic paper may be used.
The first sheet 21 has a zone of weakness 22 formed thereon. This zone of weakness may be of any convenient shape including V- ,O- ,H- , C-shaped, etc but preferably it is U-shaped as shown. The zone is formed by ultra-sonic welding and at the same time a tag 23 of similar material but preferably of a different colour, for asethetic reasons, is welded to the zone. For a U-shaped zone the tag is welded to the base of the "U". The zone of weakness provides an easy tear path for opening the package and the tag provides a convenient handle by which the package can be opened to initiate tearing along the zone of weakness 22.
The second sheet 24 of the envelope may be printed with indicia 25 such as product description, trade mark, manufacturer etc. The printing may be carried out by a screening printing process. If the printing is applied to the inside surface of the sheet 24 the printing cannot be removed without opening the package.
The sponge 11 is packaged by placing the sponge between sheets 21 and 24 and compressing the sponge to expel the air from the sponge. awhile the sponge is compressed the envelope is formed by sealingly welding the two plastics sheets together. The thus sealed envelope prevents air from returning to the sponge after the compression force is removed and thus the sponge stays substantially in its compressed state.
To open the package, the tag 23 is pulled to tear the weakened zone to gain access to the sponge which can then be removed by way of the opening created. The sponge, once the packaging is opened, begins to absorb air and resumes its original shape. If the envelope is not properly sealed the sponge absorbs air and tries to regain its original shape. Thus, if the packaged sponge is tampered with resulting in the seal being broken, the sponge tries to resume its original shape and the broken seal is clearly evident by the expanding sponge.
Figures 4 and 5 illustrate a machine for packaging the sponges. The machine 30 is an ultra-sonic welder used for welding plastics materials. The machine illustrated has two operating work stations 31 and 32, one at each end of the machine. Each work station has a work plate 33 and an anode or welding horn 35, 36. The parts to be welded are placed on the work plate and pressed by the welding horn as a high frequency current is passed through the material resulting in localised fusion and bonding of the plastics material.
At work station 31, the first sheet 21 and the tag 23 are welded together as the zone of weakness is formed. This is carried out by using a U-shaped welding horn 35 shown in Figure 5. The zone of weakness is formed by welding a seam across the sheet. At the same time the tag 23 is welded to the sheet at an appropriate point along the seam or zone of weakness 22.
At work station 32, the sponge is packaged. The welding -horn 36 for work station 32 is arranged to weld a seam around the sponge joining the two sheets 21 and 24 together and thus in the preferred embodiment the welding horn 36 has a rectangular foot print. The first sheet 21 is placed on the work plate 32 with the tag 23 against the plate. The sponge 11 is placed on the first sheet and the second sheet 24 is placed on top of the sponge. The welding head 37 is lowered to compress the sponge and press the first and second sheets together. Once the sponge has been sufficiently compressed the welding horn 36 is activated to sealingly weld the two sheets together to enclose the sponge 11 within the sealed envelope 20. Once the two sheets have been welded together the package is removed from the welder and this sponge remains in its compressed stage as its sealed envelope prevents air from returning to the sponge to allow it to resume its original shape.
As will be appreciated, this invention can be applied to any sponge and provides a compact package giving a ready indication if the seal has been broken. The envelope may be formed by a single sheet folded to form the two sides of the envelope. In this arrangement joining is required on three sides only.
Also, the zone of weakness may be formed by applying heat to the sheet to produce an area of reduced material strength.
