This application is a national stage entry under 35 U.S.C. 371 of international application PCT/ZA2005/000062, filed 3 May 2005 which claims priority to South African patent application ZA 2004/3610, filed 12 May 2004, the specifications of which are hereby incorporated herein by reference.
THIS INVENTION relates to condom applicators.
The problems inherent in the application of condoms, and in known applicators, are discussed in WO 02/069861A1. This PCT specification discloses an applicator which is an improvement on those disclosed in the art represented by, for example, U.S. Pat. No. 4,875,491.
The present invention seeks to provide a still further improved condom applicator.
According to one aspect of the present invention there is provided a condom applicator which comprises a base comprising at least two separable parts, each part having a section of a trough therein and the trough sections of the parts together defining an upwardly open trough for receiving the hem ring of a condom, the trough having an inner circumferentially extending wall and an outer circumferentially extending wall and at least two flaps having areas which cover the trough whilst leaving a circumferentially extending gap between said inner circumferentially extending wall and edges of the flaps.
The trough is preferably circular in plan but it can also be oval.
Said applicator preferably comprises two base parts held together by one or more frangible bridges, each part having one half of the trough therein.
Said flaps are preferably connected to said base parts by film hinges.
Said inner and outer walls of the trough preferably diverge so that the trough is wider at its mouth than at its base. Either both walls can slope or one can be vertical and the other can slope.
Said area of each flap can be below the level of the remainder of each flap, there being inclined walls joining said areas and said remainders.
The upper edge of said inner wall is preferably at a level above that of said area of the flap whereby said gap is defined between the edges of the flaps and the outwardly facing surface of said inner wall.
Tabs for holding the condom's nipple in a compressed condition can be provided. The tabs can be connected to the flaps by film hinges and can lie across the opening in the applicator which is bounded by the inner wall of the trough. The tabs can each extend fully across said opening or part way across the opening.
The applicator can comprise two separate parts forming a base and two separate flap parts, there being means for enabling each base part to be secured to one of the flap parts.
In a modification of this form said two base parts are connected together by frangible bridges and the two flap parts are connected together by frangible bridges.
The connecting mean preferably comprises locking tabs which fit into sockets.
According to a further aspect of the present invention there is provided, in combination, an applicator as defined above and a condom, the hem ring of the condom being in said trough and the side wall of the condom being in said gap with the nipple end of the condom extending across the opening in the applicator bounded by said inner wall.
According to another aspect of the present invention there is provided a package comprising two pieces of material each piece of material being a laminate of an aluminium foil with synthetic plastics material on each side thereof, said pieces being heat sealed around the edges thereof and there being registering lines of perforations across the outer layers of plastic and nicks in the material at the ends of these lines.
The laminate is preferably polyester, for the outer layer, aluminium and then polythene for the inner layer.
For a better understanding of the present invention, and to show how the same may be carried into effect, reference will now be made, by way of example, to the accompanying drawings in which:-
Referring firstly to
The base 12 is moulded in two parts 12.1 and 12.2 with a split line 18 between them. To ensure that the parts 12.1 and 12.2 do not separate during packaging of the condom, thin webs (not shown) can bridge the split line 18. These provide insignificant resistance to breaking along the line 18 when such action is required.
The base 12 comprises two planar sections 20 each of which incorporates a semi-circular trough 22. Each trough 22 is bounded by a radially inner wall 24 (see particularly
Interlocking pins 30 protrude upwardly from the sections 20 and a strengthening rim 32 extends around the outer edge of the lower surface of the base 12.
The flaps 14 are joined to the edges of the parts 12.1, 12.2 remote from the trough 22 by way of film hinges 34. Each flap comprises a planar area 36. One edge of each area 36 is joined by the film hinge 34 to the base 12. Strengthening flanges 38 protrude upwardly from the areas 36.
Each flap 14 has a semi-circular depression 40 along its remaining edge. The depression comprises a circumferentially extending semi-circular inclined wall 42 and a semi-circular flat area 44 which are best seen in
Sockets 46 are provided in the areas 36, the sockets serving to receive the pins 30.
The tabs 16 are connected to the flaps 14 by way of film hinges 48. It will be noted that the tabs 16 are not shown in
The underside of each flap 14 (see
Clips are provided at 52 on the flaps 14.
With the applicator as shown in
The flaps 14 are then displaced through 180° to the positions shown in
The tabs are pressed down to the positions shown in
Once the applicator has been removed from its package (as will be described hereinafter), the applicator is gripped on each side of the split line. Flexing the applicator causes any flimsy connection between the two parts to fail. Only the hem ring H now holds the two parts together.
As the applicator is slid along the erect penis, the condom unrolls from the hem ring and feeds out through the gap between the inner peripheries of the flaps and the radially outer face of the inner wall of the circular trough.
Turning now to
Gripping handles 118 protrude outwardly from the wall 110.
Inter-locking tabs 120 are provided which protrude upwardly from the wall 110.
The part 102 can be moulded in halves, the halves abutting along the centre line L. For ease of handling, however, it is preferred that the part 102 be moulded as a single component with flimsy, frangible moulded bridges connections extending across the centre line L.
The part 104 comprises a wall 122 which matches the wall 110 in shape. Sockets 124 in the wall 122 receive the locking tabs 120 protruding from the wall 110.
Inwardly of each half of the wall 122 there is a flap 126 which has an inner edge which is of generally semi-oval shape. A semi-circular cut-out 128 is provided in the edge of each flap 126.
Gripping handles 130 protrude outwardly from the wall 122 and match the handles 118 in shape.
At each end of each handle 118, 130 there is a tab 132 with a circular hole 134 in it. If desired only the part 102 or the part 104, but not both, has tabs 132.
The part 104 can, in the same way as the part 102, be moulded in halves. However it is preferred that it be moulded in one piece with flimsy bridges extending across the line LI.
Strengthening ribs 136, which are on the top faces of the flaps 126 as they are viewed in
The hem ring H (
Lubricant can be fed into the trough through the cut-outs 128. The part 104, inverted from the position shown in
The flaps 126 cover the trough in which the hem ring is located (see
The inner edges of the flaps 126 lie adjacent the wall 108, there being a gap wide enough for that part of the cylindrical wall of the condom adjacent the nipple to pass through.
As shown at 140 in
The condom is applied by flexing the applicator along the registering lines L and LI and pulling the two halves apart. If there are flimsy connections they break at this stage. The applicator is slid along the penis causing the condom to unroll and feed out of the trough through said gap.
Once the condom is fully unrolled, the two halves are tilted with respect to one another using the handles 118, 130 and simultaneously pulled apart. The hem ring displaces the flaps 126 and comes free of the applicator which is now in two separate halves.
In
The foil is manufactured in strip form and rolled. At intervals along the length of the roll there are transverse lines of perforations. Each perforation can be, for example, 1 mm long with a gap of 1 mm between itself and the next perforation. The perforations are cut partially through the polyester layer but not through the polyethylene or aluminum layers.
At each end of each line of perforations the foil is cut. The cuts are preferably V-shaped and extend inwardly for, for example, 2 mm from the edge of the strip. The perforations thus extend between the cuts.
Two foil strips are fed forward and the applicator placed on the lower of the advancing strips with a line of perforations across the applicator. A heated former, preferably of aluminium, then produces a substantially square seal S which encloses the applicator.
To remove the applicator the package is torn along the line of perforations. The cuts assist in the commencement of the splitting action.
The foils can be sealed through the holes 134 to located the applicator in the package.
