Safety Seal Cap Thefollowing statement is a full description of this invention, including the best method ofperforming it known to me.

The invention is described in the following statement: Safety Seal Cap This invention is in the area of tamper-evident capping devices that are used to seal bottles containing valuable liquids and prevent the bottles from being re-filled.

The following known solutions are similar to the invention: WO 96/23904 Al, 08. 08. 1996 RU 2150417 C1, 10. 06. 2000 GB 2218590 A, 13. 12. 1989 S The known capping devices contain a dispenser, securing cap, valve, seal, cap-like plug and safety collar. The cap and safety collar are connected loosely by several joints. The dispenser has ridges distributing the flow. The safety collar has a flange on its internal side that engages with the dispenser collar. The valve prevents the bottle from being re-filled. The cap is screwed onto the dispenser and sealed to it by a sealing V-ring.

The similar solutions have a number of shortcomings that show themselves in various situations. In particular, if the bottle is tipped at a small angle the valve may jam inside the guide due to the short length of initial positioning of the valve in the guiding plane. The known designs use a cap-like plug and a securing cap that engage with one another, making the manufacturing more expensive. Short joints made of medium-rigid plastic and S-connecting the plug and securing collar, make it harder to unscrew the cap as excessive force needs to be applied to tear it off.

The technical advantage of the invention is that it makes the safety seal cap more convenient to use. This is achieved thanks to incorporating in the design of the safety seal cap a decorative housing containing a tear-off flap in its vertical part. When the housing is rotated in relation to the bottle, the tear-off flap comes off making an opening in its place, and a nozzle comes out through the opening so that the liquid could be dispensed from the bottle.

When the housing is rotated back, the nozzle retracts and its opening through which the liquid passes, gets shut off. The number of parts used in the safety seal cap, is reduced significantly, leading to its lower cost.

The invention is illustrated in the following Figures: Fig. 1 General (Assembled) View of the Safety Seal Cap Fig. 2 Decorative Housing Fig 3 Securing Collar Fig. 4 Lid Fig. 5 Dispenser The safety seal cap contains decorative housing 1, securing collar 2, lid 3 and dispenser 4.

The decorative housing 1 has cup 5 and grooved rim 6 in its upper part. The tear-off flap 7 is fixed to the solid top of the housing 1 by joints 8. The securing collar 2 contains cup 9 whose top part 10 has opening 11. The cup 9 has locating ridges 12 used to mount the collar 2 tightly inside the decorating housing 1. The top of the collar 2 has guiding lugs 13 and guiding slots 14. The lugs 13 and slots 14 are located in the top part of the collar along its S•axis. The lugs 13 and slots 14 are located in groups, with each group having one lug 13 and 0 0 0two slots 14 spaced on either side of the lug. There may be three groups containing lugs and slots. In that case, the groups would be spaced at a 120-degree angle. The depth of slot 14 is somewhat greater that the height of lugs 13. The internal bottom part of the cup 9 contains ee.eei stopping lugs 15. They are positioned at a 90-degree angle to the collar 2 axis, between the lug-slots groups, and are also spaced at a 120-degree angle. The top internal part of the cup 9 has a thickening 16 whose size exceeds the length of the lug 13 and slots 14.

The lid 3 contains a nozzle 17 that has an opening 18. Ridge 19 and cup 20 installed inside S•the lid 3, are located against the nozzle 17. A cup 21 is made along the lid 3 circumference; the cup's internal surface has thread 22 while its external surface has slots 23. The slots 23 are coaxial to the cup 21 and their size allows for loose insertion between the lug 13 surface and the lateral surface of the closest slot 14 of the securing collar 2.

The dispenser 4 has an external cup 24 and, coaxial to it, an internal cup 25; the two are joined together by part 26. The gap between the cups 24 and 25 is of such size that it allows a bottle neck to be pressed (crimped) into it. A ring-shaped ridge 27 with thread 28 is made in the top of the dispenser 4, coaxial to cups 24 and 25. The thread 28 is made on the external surface of the ridge 27 and its size matches the thread 22 made in the lid 3. The internal diameter of the ring-shaped ridge 27 is the same as the external diameter of the cup (lid Edges 29 are made inside the ring-shaped ridge 27; their lower part is aligned with the upper part of the internal cup 25. The top parts of the edges 29 are secured to V-ring 31 outer surface by disk 30. The surface size is such that it allows to shut off securely the opening 18 in the lid 3.

The top part of surface 31 is somewhat higher that the ring-shaped ridge 27. The external bottom part of the cup 24 has a ring-shaped ridge 32. The diameter of the ridge 32 is somewhat less than the internal diameter of the cup 9 (collar The external surface of the cup 24 has edges 33 that are coaxial to it. The number of edges 33 may be 4. The bottom internal surface of the cup 24 contains edges 34 that are coaxial to it. A ring-shaped ridge is positioned over the edges.

The safety seal cap is assembled as follows: The dispenser 4 with the lid 3 screwed onto it by means of the thread 28, is inserted in the securing collar 2. As a result, the slots 14 of the collar 2, enter the spaces between the slots S- 23 on the lid 3, while the ring-shaped ridge 32, edges 33 and stopping lugs 15 of the dispenser 4, set the lid 3 in a position relative to the internal surface. The dispenser 4 is set •in place so that it can be rotated relative to the securing collar 2. This feature is provided by S"the above design of safety seal cap parts as well as by the fact they are made of an antifriction material, for example, plastic. The metal decorative housing 1 is placed on top; it places the securing collar 2, lid 3 and dispenser 4 in a fixed position along its internal surface ••go and locating ridges 12 of the collar 2. The safety seal cap is placed on a bottle; the top of the bottle inserts tightly into the gap between the external cup 24 and internal cup 25 of the o 0 dispenser 4. The bottle neck is secured by means of the ring-shaped ridge 35 and edges 34 of the dispenser 4. This safety seal cap design allows to reduce the number of parts used in it and, therefore, lower the safety seal cap cost, and, at the same time, make it more o conveient to use.

ooooo How to operate the safety seal cap The decorative housing 1 is rotated by hand. As a result, the securing collar 2 also rotates relative to the bottle and dispenser 4. As the slots 14 of collar 2, slots 23 of lid 3, thread 22 and thread 28 engage with one another, the lid 3 moves along the cup's axis. By moving the nozzle 17, the lid 3 pushes out the tear-off flap 7 and breaks the joints 8. The nozzle 17 comes outside the decorative housing and, at the same time, the V-ring 31 of the collar 2, uncovers the opening for passing the liquid from the bottle. When the decorative housing is rotated back, the lid 3 is placed on the V-ring 31 (dispenser 4) and shut off the opening, because the surfaces of cup 20 (lid 3) and ridge 27 (dispenser 4) are matched tightly.

Brief Technical Description of the Safety Seal Cap The safety seal cap containing a housing with a tear-off flap, securing collar and dispenser, is different from others because of the following: the dispenser has a threaded ring-shaped ridge; screwed to the ridge is a housing containing a nozzle for dispensing the liquid, and slots on its external lateral surface; the tear-off flap is located in the top part of the decorative housing; a securing collar containing slots on its internal surface, is mounted inside the decorative housing, so that the collar and the housing can be rotated relative to the dispenser, and that its slots can engage with the lid slots, making the lid move along its axis, push the nozzle and remove the tear-off flap.
