A high score is rewarded by skipping distant targets and aiming at a target nearer the tee area. According to the invention, at least one of the targets includes front and rear surfaces, spaced to allow a golf ball to pass therebetween, the front surface providing a ramp at ground level, both surfaces substantially preventing rebound of a ball landing thereon, and means for detecting upon which surface the ball stops its movement and for indicating a corresponding score. A separate tee area G is provided for target G (which may be skipped if a high score is achieved at D, E or F). The simulated hole is finished by putting into a hole 15 from position 1, 2, 3 or 4 (depending upon previous shot performance at D, E, F or G). A bunker 13 is provided. Three simulated holes having individual putting areas, but sharing some of the targets A-G, may be situated adjacent each other, Figs. 2 and 5 (not shown). Parts of the course may be floodlit or covered. One of two alternative forms of target structure may be provided. A first form, Figs. 3-4 and 9-12 (not shown), comprises inclined fences extending transversely to the flight of the ball and arranged one behind the other, the height of successive fences increasing from front to rear and the material and/or mounting of each fence being such that a flighted golf ball landing thereon does not rebound appreciably. The channels between adjacent fences are divided into high-scoring central zones and low-scoring lateral zones. Switches in the base of each channel may detect the presence of a ball and cause the appropriate score to be indicated at the tee area. The front fence presents a ramp up which a ball rolling towards the target may travel. The second form of target structure, Figs. 6-8 and 13-16 (not shown), comprises an array of concentric annular channels associated with respective scores which increase towards the centre of the array. The array is inclined and its lower, forward end is straight and touches the ground to form a ramp. Ball detecting switches are again provided.

[Also in Division B8] A screw cap 20 is rendered tamper-proof by a frangible ring 50 whose upper and lower inwardly projecting flanges 52, 54 engage respectively an annular bead 28 rolled at the extremity of the skirt 24 of the cap 20 and an annular projection 16 on the neck of the container. As unscrewing of the cap is initiated the circumferential stress set up in the ring leads to fracture at one of a number of weakening longitudinal score lines (56), Fig. 3 (not shown), continued unscrewing dividing the ring into sections which pivot at neighbouring score lines and are easily removed to leave a simple screw cap. Rings 50 are formed from a continuous strip of material. Scoring is carried out by a device Ss comprising rolls 80, 82, the latter having peripheral scoring elements 83, and the strip is fed into a cutting and sealing station Sc by rollers 94 through a slotted guide opening 92 in a work head 85. The strip is bent to circular shape between the walls of a circular opening 90 in the work head 85 and a mandrel 89, and a reciprocating cutter 96 cuts off a predetermined length of strip. Before the cutter 96 reaches its fully extended position a seating rod 100 which is normally held in a retracted position is actuated inwards to press the leading end of the strip segment against the mandrel 89 so that the ends of the strip segment overlap when the cutter 96 descends and may be sealed together by the pressure of a heating element 102, a coating of bonding material having been initially applied at least to one surface of the strip. The turret mounting 87 supporting the ring on the mandrel 89 is then rotated 90 degrees to convey the ring to a rolling station Sr where the upper annular flange of the ring is formed by a rolling mechanism 110, the mandrel 89 being partly retracted so that its upper edge forms a die, controlling the profile of the rolled flange of the ring, Figs. 10-12 (not shown).
