Definitions

  • the present invention relates to a tablet dispenser, like, for example, a dispenser of a solid cleaning and/or deodorant product in a toilet bowl or of a cleaning product in an automatic dish washing machine or the like, which enables the dissolution of these contained tablet(s) in a liquid medium.
  • tablette will refer to any form of particulate solids.
  • the tablet provides a number of advantages to both the consumer and the manufacturer. Indeed, said tablet prevents spillage of the cleaning and/or deodorant composition. Furthermore, said tablet eliminates the need for the user to estimate the dosage of the cleaning and/or deodorant composition required and ensures that the correct dosage of cleaning and/or deodorant composition is used.
  • cleaning tablets are available on the market for dish washing. These tablets are generally sold packed in containers in a loose way or individually wrapped in bags. Separately, dispensing devices enabling to contain and to dispense these tablets are also available. Indeed, once this dispensing device containing a tablet is placed into an automatic dish washing machine this dispensing device enables the dissolution of the tablet in the wash liquor. Such a dispensing device is, for example, described in the co-pending European patent application No. 95304115.9.

  • FIG. 1 For example, in EP-A-166 374.
  • these dispensers require an additional secondary package. This secondary package ensures that the cleaning and/or deodorant tablets contained in the dispensers are protected from the exterior to avoid deterioration of the tablet before these tablets are actually placed and used in the toilet bowl.
  • the secondary package has the following disadvantages.
  • the dispenser containing the tablet and the corresponding secondary package have to be produced independently from each other. Indeed, usually two different machines and two different materials are needed to make the dispenser containing the tablet and the corresponding secondary package.
  • the dispenser has to be put into or assembled into the secondary package. The additional manufacturing steps to produce the secondary package and to place the dispenser into said secondary package complicates the total manufacturing process, adding costs to the package.
  • Another disadvantage of the secondary package is that this secondary package can not be usually reclosed once it has been opened, e.g. when the user opens the secondary package by mistake, with inevitable deterioration of the tablet. Indeed, the secondary package has usually no reclosing features such that said dispenser can be stored again in this secondary package.
  • the secondary package loses its function once it has been opened.
  • the present invention is a tablet dispenser comprising means for holding said tablet dispenser such that a tablet is gradually dissolved in a liquid medium when said tablet dispenser is in use.
  • Said means for holding said tablet dispenser comprises means for protecting a tablet from deterioration when said tablet dispenser is not in use.
  • methods of making a tablet dispenser include the step of thermoforming a tablet dispenser, or of cutting out a sheet such that a tablet dispenser can be formed out of said sheet, or of wrapping a sheet around a tablet.
  • a tablet dispenser as a dispenser of a cleaning and/or deodorant product on toilet bowl rim, or as a dispenser of a cleaning and/or perfume product in a toilet flushing water tank, or as a dispenser of a cleaning product in an automatic dish washing machine is disclosed.

  • Figure 12b showing a perspective front view the tablet dispenser formed from the blank of Figure 12a.
  • the tablet dispenser (10) of Figure 1a is shown in a perspective front view in its closed position.
  • This tablet dispenser comprises a means for holding said tablet dispenser (11) and outer walls (12).
  • said outer walls define a rectangularly shaped container (Fig. 1b, 12').
  • Said outer walls contain the tablet.
  • One half of said outer walls further comprise orifices (14), as shown in Figure 1c.
  • Said orifices allow the dispensing of the dissolved part of the tablet.
  • Said means for holding said tablet dispenser lies upon one half of the outer walls.
  • the means for holding said tablet dispenser is a pre-bent clip (Fig. 1b, 11'). This clip corresponds to the shape and form of said outer wall, such that one half of outer walls is completely covered.
  • said orifices (Fig. 1c, 14) are covered by said clip.
  • said clip covering said orifices provides product and/or perfume protection of said tablet during shipment and storage without needing any additional secondary package around said tablet dispenser. Therefore, this clip is also the means for covering a tablet and which protects the tablet from the exterior when said tablet dispenser is not in use.
  • the dimensions of said clip (11') should correspond at least to the width of the supporting structure upon which said tablet dispenser is applied.
  • said clip should correspond to the width of the rim (100) of a toilet bowl such that said tablet dispenser is firmly held onto the rim, as shown in Figure 1d.
  • the dimensions of said clip should correspond the rim of the cutlery basket, for example.
  • said clip may be sufficiently flexible such that said clip may be bent over the rim of a toilet bowl or a cutlery basket, even if the dimensions of said clip are smaller than the width of the rim when said clip is not flexed.
  • said clip is U-shaped, as shown in Figure 1b.
  • One end of said U-shaped clip is free (16), whereby the opposing end (18) is connected to a transition piece (15).
  • the free end (16) of said U-shaped clip is longer than the corresponding opposed end (18). Indeed, the free end of said U-shaped clip goes over the rim of the supporting structure upon which said tablet dispenser is applied.
  • Figure 1d represents an example of a tablet dispenser held on the rim of a toilet bowl. We found that a further elongated free end improves the holding of said tablet dispenser.
  • Said transition piece (15) is a frame defining a free space (15'). Said free space is such that said outer walls (12) are able to pass at least partially through said free space between said frame.
  • Said transition piece is connected to said clip on one end and to said outer walls at the opposed end. Both connections are hinged such that said clip and said end walls can at least partially pivot around said frame.
  • the end (18) of said clip is connected to the part of said frame opposing the connection between said frame and said outer walls.
  • the connection between said transition piece and said outer walls is achieved at one corner of a rectangularly shaped container defined by said outer walls.
  • this tablet dispenser in its closed position as shown in Figure 1a starting from the open position of Figure 1c, said frame is rotated so that said frame passes over the outer walls, as shown in Figure 1b. Then the clip is rotated in such a manner that said clip covers one half of said outer walls reaching the position of Figure 1a. The reverse is done to achieve again the open position of Figure 1c.
  • said outer walls (12) may comprise orifices on any other side or half of said outer walls.
  • a liquid medium may enter from one half of said outer walls, dissolve the tablet contained within said outer walls and the dissolved part of said tablet exits from the opposed side with respect to the entered liquid medium.
  • orifices may be located towards the inner wall of said rim to facilitate the entering of liquid medium of the flushing into said outer walls.
  • orifices located opposed to the previous ones facilitate the exit of the dissolved parts of said tablet contained within said outer walls.
  • said tablet dispenser may further comprise additional means to said clip for covering and protecting the tablet from the exterior to avoid deterioration of the tablet when said tablet dispenser is not in use.
  • This additional means may be a plastic sheet attached to the free end (16) of said clip. This plastic sheet goes around said outer walls such that all the remaining orifices are covered protecting the tablet from the exterior. Said plastic sheet may be provided with an adhesive part such that said sheet may be adhesively attached on said clip or on said plastic sheet again once all the orifices are covered.
  • the adhesive part of said plastic sheet is preferably made of glue, like, for example Wet-Surface Acrylic #1100 glue supplied by 3M.
  • said tablet dispenser may be further packaged in a secondary package with or without the additional plastic sheet.
  • the means for holding said tablet dispenser (11) is completely made of a completely flexible sheet (20), as shown in Figure 2b.
  • this completely flexible sheet acts also as means for covering the tablet and protecting the tablet from deterioration when said tablet dispenser is not in use.
  • said plastic sheet when said plastic sheet is wrapped around said outer walls (12), said plastic sheet can cover all the orifices (14) placed around the axis defined by the attachment between said flexible sheet and said outer walls.
  • Figure 2a illustrates said tablet dispenser when said flexible sheet is wrapped all around said tablet dispenser, i.e.
  • Figure 2a represents the tablet dispenser in its closed position. The open position is shown in Figure 2b and Figure 2c illustrates the tablet dispenser attached over the rim (100) of a toilet bowl.
  • This same tablet dispenser can be applied also to a cutlery basket in an automatic dish washing machine as the embodiment described before.
  • this means (11) for holding said tablet dispenser due to the flexibility of the flexible sheet results in a tight fit around any supporting structure upon which said tablet dispenser is applied.
  • said means for holding a tablet dispenser has the advantage of fitting easily on a non uniform supporting structure, like the rims of toilet bowls, which differ slightly in dimensions between each other.
  • said tablet dispenser may be further packaged in a secondary package.
  • FIGs 2b and 2c There are different options to attach said tablet dispenser with said flexible sheet onto a structure.
  • the attachment means is an adhesive part (21).
  • This adhesive part adheres to the toilet bowl attaching said tablet dispenser under the rim of the toilet bowl.
  • FIG 2d Another possibility is shown in Figure 2d.
  • the flexible sheet is engaged into a hook (22).
  • Said hook is preferably attached to the supporting structure, e.g. to the outside of the toilet rim using, for example, adhesives or a mechanical suction clip.
  • Said hook may have different forms, for example, as a hook, as shown in Figure 2e, or as a button as illustrated in Figure 2f or a cut out hook as shown in Figure 2g.
  • Said flexible sheet comprises, for example, a simple cut (23) through the thickness of said flexible sheet corresponding to said hook such that said cut engages said hook, and consequently holding said tablet dispenser in said toilet bowl.
  • the flexible sheet (20) may be preferably made of a plastic material.
  • This plastic material should be flexible enough such that said flexible sheet can wrap around said tablet dispenser in its closed position and conform to the shape of the rim of a supporting structure, like a toilet bowl when said tablet dispenser hangs in said toilet bowl.
  • said plastic material should be resistant to a certain degree of mechanical stresses when holding the tablet dispenser in said toilet bowl to avoid risks of breakings of the flexible sheet, especially at the cut (23) and at the connection between said flexible sheet and said outer walls.
  • a layer or liner of EVOH works as a barrier for moisture and perfume.
  • Materials other than EVOH which provide a barrier for moisture and perfume may be also chosen for the present invention.
  • said outer walls are made of the same material as said flexible sheet.
  • the thickness of the material for said outer walls may be different from the thickness of the material for said flexible sheet.
  • the means for holding said tablet dispenser and the means for covering and protecting the tablet may be also made of water soluble materials, like, for example, the following water soluble films Mowiol® 888 by Hoechst, KU HH40® by Soltech and Polyox® by Union Carbide.
  • First step is to form a sheet of plastic (Fig. 3a, 30).
  • the outer walls (12) are formed as shells by thermoforming (Fig. 3b).
  • the thickness of the plastic sheet after thermoforming may be preferably within a range of about 10 ⁇ m to about 1 mm, more preferably within a range of about 20 ⁇ m to about 500 ⁇ m, most preferably within a range of about 20 ⁇ m to about 150 ⁇ m. In this manner parts of said plastic sheet are very flexible where the thickness is smaller, whereas other parts of the same plastic sheet are stiffer where the thickness is greater.
  • said means for holding said tablet dispenser is a clip, as described, for example, in Figures 1a to 1d, then also said clip is formed by thermoforming or bending.
  • said flexible sheet as a means for holding, as described in Figures 2a to 2d
  • said flexible part of said plastic sheet extends away from the thermoforming manufacturing process.
  • said orifices (14) on said outer walls are cut off or stamped out (Fig. 3c) on a support (6).
  • said tablet dispenser comprises a flexible sheet as the means for holding, the cut (23) of said flexible sheet is also cut off or stamped out and said flexible sheet is cut in the desired shape and length.
  • a tablet (5) of detergent and/or perfume product is placed in one of the shells (Fig. 3d).
  • the product can be extruded in solid form and then placed in the shell.
  • Another possibility is to inject the product in a liquid form and place the product still in liquid form in the shell where the product solidifies into the corresponding shape of the shell.
  • the shells or the outer walls can now be sealed together by heat sealing or with appropriate adhesives (Fig. 3e).
  • said means for holding the tablet dispenser further comprises means for covering and protecting the tablet from the exterior to avoid deterioration, then the clip as described, for example in Figure 1a to 1d is pivoted over the outer walls of said tablet dispenser closing the orifices. Otherwise, at least part of said flexible sheet is wrapped around said shells or outer walls closing said orifices.
  • FIGs 4a and 4b Another improved means (30) for holding said tablet dispenser is shown in Figures 4a and 4b.
  • Figure 4a shows the improved means for holding said tablet dispenser in the position when said means for holding said tablet dispenser is not used.
  • Said improved means for holding comprises a blank (31) and a certain pattern of cuts (32) through the thickness of said blank.
  • the pattern of cuts on said blank are such that a clip (33) can be unfolded as shown in Figure 4b.
  • the unfolded clip comprises a restraining part (34) connected to the rest of said blank with at least an arm (35).
  • the restraining part goes over supporting structure upon which said tablet dispenser is applied acting like the free end (16) of the U-shaped clip in Figure 1d.
  • the arm remains on the top edge of said supporting structure. We found that this clip ensures the holding of a tablet dispenser.
  • the blank (31) is made of a material such that the blank can be resiliently deformed to unfold the clip (33) as in Figure 4b. Nevertheless, this same material has to be sufficiently resistant to be able to hold the corresponding tablet dispenser.
  • said blank is made of plastic materials, and preferred plastic materials are PET, PP, HDPE and polyethylene with a layer of EVOH.
  • this means (30) for holding said tablet dispenser due to the resilient deformability of the blank results in a tight fit around the toilet rim.
  • said means for holding a tablet dispenser has the advantage of fitting easily on a non uniform supporting structure, like the rims of toilet bowls, which differ slightly in dimensions.
  • said blank formed into a tablet dispenser may be further packaged in a secondary package.
  • FIG. 5a shows the tablet dispenser (40) comprising the means (30) for holding said tablet dispenser described before in figures 4a and 4b.
  • Said tablet dispenser further comprises said means (41) for covering and protecting the tablet from the exterior.
  • An example of means for covering and protecting is a flexible sheet. When the tablet dispenser is in its closed position, the flexible sheet covers all orifices (14) of said tablet dispenser, as shown in Figure 5a.
  • Said means is attached to said tablet dispenser to keep said tablet dispenser in closed position covering and protecting the tablet.
  • the attachment between said flexible sheet and said tablet dispenser may be achieved, for example, by an adhesive part on said flexible sheet or tablet dispenser.
  • Figures 5c to 5e illustrate in a side view that when said flexible sheet is detached from said tablet dispenser, said flexible sheet also helps to unfold the clip (33) of Figures 4a and 4b.
  • the unfolded clip is also shown in a perspective front view in Figure 5f.
  • Said flexible sheet (41) is connected to part of said blank (31).
  • said flexible sheet is connected to the restraining part (34) such that the clip is unfolded when said flexible sheet is detached from said tablet dispenser.
  • said flexible sheet may be used only to facilitate the opening and usage of the tablet dispensing. Indeed, facilitating the unfolding of said means for holding said tablet dispenser makes said tablet dispenser very user friendly.
  • the means for covering and protecting said tablet may be then achieved by an additional secondary package.
  • the connection between said flexible sheet and said blank may be an adhesive connection (36) as shown in Figure 5e. Another possible connection is achieved through a perforation line (37) between said blank and said flexible sheet as shown in Figure 5b.
  • the adhesive connection and the perforation line may be used to connect any means for holding the tablet dispenser with any means for covering and protecting the tablet as described herein before and hereinafter.
  • said blank formed in a tablet dispenser may be further packaged in a secondary package with or without the additional flexible sheet.
  • the method to manufacture the tablet dispenser made of plastic material according to any of the embodiments of Figures 4 and 5 ( Figures 6a and 6b) is very similar to the method described above in Figures 3a to 3e.
  • the outer walls (12) are formed as shells by thermoforming.
  • the thickness of the blank (31) of plastic of Figure 6a after thermoforming is again variable preferably within a range of about 10 ⁇ m to about 1 mm, more preferably within a range of about 20 ⁇ m to about 500 ⁇ m, most preferably within a range of about 20 ⁇ m to about 150 ⁇ m.

  • the part of said blank acting as the means for holding is cut in the desired shape and length.
  • stiffer parts of said tablet dispenser can provide flexibility to certain parts of said table dispenser. Indeed, with specific cuttings through the thickness of part of blank the means for holding said tablet dispenser as described in Figures 4a and 4b is formed.
  • the tablet of detergent and/or perfume product can be placed in one of the shells.
  • the product can be extruded in solid form and then placed in the shell.
  • Another possibility is to inject the product in a liquid form and place the product still in liquid form in the shell where the product solidifies into the corresponding shape of the shell.
  • the shells or the outer walls can now be sealed together by heat sealing or with appropriate adhesives (Fig. 6b).
  • said means for holding the tablet dispenser further comprises means (41) for covering and protecting the tablet from the exterior in form of a flexible sheet, said flexible sheet is wrapped around said shells or outer walls closing said orifices.
  • the means (11) for holding the tablet dispenser has to be adaptable to non-uniformed sizes and dimensions of the supporting structure upon which said tablet dispenser is applied.
  • the rim of a toilet bowl (100) for example, differs from country to country, and even within the same country between different manufacturers. Therefore, it is desirable to have means for holding said tablet dispensers which are able to adapt to different sizes and dimensions without jeopardising a reliable holding of said tablet dispenser.
  • the means for holding said tablet dispensers described in Figures 2a to 2d and in Figures 4a and 4b are such means fitting any toilet dimensions.
  • the means (50) for holding said tablet dispenser comprises a plastic sheet which can be easily bent.

  • this tablet dispenser may be further packaged in a secondary package.
  • the tablet dispenser needs to contain the tablet and at the same time has to allow the dissolution of the tablet in a liquid medium. Usually, this is achieved with cages thermoformed or injected moulded from plastic materials. A way to reduce the manufacturing costs of said tablet dispensers would be to reduce the manufacturing costs of the cage enclosing said tablet. A possible way to achieve a reduction in the manufacturing cost is shown in Figures 8a to 8f.
  • This tablet dispenser is made of a completely flexible sheet (60). Preferably, the thickness of this flexible sheet is in the range of about 20 ⁇ m to 70 ⁇ m. This flexible sheet is wrapped around the tablet (5) to keep said tablet. The part of the flexible sheet wrapping around the tablet defines a dispensing unit (Fig.

  • Figure 12a shows a blank (90) which is a slight variation of the blank (80) of Figure 11a.
  • this blank (90) comprises the cuts as for blank (80), but only side flaps (91) which can be folded along the folding lines (drawn in punctuation). These folding lines may also be curved, as illustrated in Figure 12a.
  • said side flaps act as restraining means when a tablet is inserted into said cage. Indeed, a tablet is inserted into the cage by bending and pushing said side flaps further towards the interior down to the bottom wall (93).
  • the side flaps impede that the tablet exits again from inside the cage once the tablet is inserted into the cage. Indeed, we found that the forces exerted by said tablet are not sufficient to bend the side flaps outwards to exit from the cage.
  • the forces exerted by said tablet are due to its weight and/or additional forces acting on the tablet when the liquid medium in which said tablet is held for dissolution is in movement, as, for example, the flushing of the water under the rim of a toilet bowl, or the spraying of water in an automatic dish washing machine.
  • the tablet dispensers of Figures 9 to 12 may have any of the means for holding as described before, for example, in Figures 1, 2 and 7. As an option, the tablet dispensers described in Figures 10, 11 and 12 may be further packaged in a secondary package with or without the additional means for covering and protecting the tablet from deterioration.
