Definitions

• a Two-Piece Dispenser Cap with Security Device A Two-Piece Dispenser Cap with Security Device.
• the invention relates to a two-piece disenser cap with security device.
• the prior art comprises dispenser hoods generally used, for example, in shampoo or liquid detergent containers, where it is sufficient to rotate or slightly lift the dispenser hood, without removing it from the container; the hoods are so made that thanks to this slight lifting a passage mouth is opened, through which the product can flow.
• These containers are repeatedly opened and closed without ever removing the hood or cap, so that a small dose of product can be dispensed on each occasion.
• the prior art further teaches security capsules for bottles, constituted by two elements in which: a first, cylindrical element constitutes the cap of the bottle; a second element comprises a first ring, which is blocked in the first cylindrical element, a second ring, which is coaxially connected to the first ring by means of easy- break ribs and which constitutes the security strip of the capsule, and an additional element, coaxially connected to one of the two above-mentioned rings by means c ⁇ easy- break ribs, so that it can easily be detached on inserting the capsule on the bottle.
• the additional element can have, for example, the shape of a gasket plate between the bottle neck and the cap, or a dispenser, or a drop-counter, or the like
• a capsule of the above-mentioned type is taught in patent GB 2 141 414
• the capsule which offers the considerable advantage of exhibiting relatively low stocking and production costs, is all the same rather impractical to use, especially when the additional element is shaped and used as a dispenser, for the liquid can exit only when the first element or cap has been fully removed from the bottle; the capsule in fact, cannot operate in the above-mentioned typical way of rapid-opening dispenser hoods.
• a principal aim of the present invention is to obviate the above-mentioned limits and drawbacks in the prior art by providing a two-piece assemblable dispenser cap having a security device, being relatively economical to produce, store and assemble and able to be opened and closed very rapidly and practically.
• An advantage of the dispenser cap is that it guarantees maintenance of good vacuum conditions in the container it
• a further advantage is that it is applicable to already- existing container types.
• figure 1 is a vertical elevation in longitudinal section divided into two parts of the cap of the invention applied to a container, in which in the left part the container is closed by the cap in an unopened configuration, while in the right part the container is open with the security strip having been separated from the rest of the cap.
• 1 denotes in its entirety a dispenser cap in two pieces and including a security device, destined to be applied on a neck 3 of a contai ner 2.
• the dispenser cap 1 comprises a first part 4 applied solidly by jointing on the neck 3 of the container 2 such as to close the mouth.
• the dispenser cap 1 also comprises at least one central and annular orifice 5 through which a product contained in the container 2 can pass.
• An annular projection 14 on the first part 4 engages with an undercut 15 on the neck 3 of the container 2 so as to prevent the first part 4 from rising with respect to the container 2 after assembly.
• a cylindrical body 19 made in a single piece with the first part 4 projects coaxially upwardly.
• a central element 20 having a superiorly- closed hollow body shape, coaxial to and having a smaller diameter than the cylindrical body 19, so that an annular channel is afforded between the cylindrical body 19 and the central element 20, opening inferiorly in the orifice 5 and superiorly at a height which is lower than the upper end of the central element 20.
• the dispenser cap 1 comprises a second part 6, coupled to the first and can rise or lower with respect thereto Preferably the two pieces 4 and 6 are coupled together by means of a screw 22 connection.
• the second part 6 superiorly exhibits a central mouth 7 for passage of the product contained in the container 2 and in communication with the orifice 5 of the first part 4.
• the second part 6 further exhibits a tubular body 23, coaxial with the central mouth 7 and projecting downwards, which tubular body 23 is made in a single piece with the second part 6 and has a greater superior internal diameter than the central element 20 of the fi st part 4
• the internal surface of the tubular body 23 interacts contactingly with the external surface of the cylindrical body 19, both said surfaces being able to drag sealedly one on the other.
• a free annular space remains between a part of the tubular body 23 and the central element 8, which space represents a sort of continuation of the conduit 21 and which reaches upward as far as the central mouth 7.
• the second part 6 can during use selectively assume a first lowered closed position, illustrated in the left part of the figure, and a second raised open position, illustrated in the right part of the figure.
• a first lowered closed position illustrated in the left part of the figure
• a second raised open position illustrated in the right part of the figure.
• the wall of the edge of the central mouth 7 of the second part 6 is settled contactingly on a wall 8 of the first part 4, which wall 8 is constituted by the upper portion of the central element 20 and which is shaped and arranged in such a way as to obstruct the central mouth 7, so that product cannot exit from the contai ner 2
• the central mouth 7 of the second part 6 is distanced from the first part 4, so that the product can exit from the container 2, more precisely, the product can pass through the orifice 5, cross the conduit 21 and exit from the central mouth 7
• the sealedly dragging contact between bodies 19 and 23 in the figure prevents undesi red loss of product.
• An annular body 11 inserted into a niche 12 afforded in the second part 6 is connected to the inferior end of the first part 4 by means of easy-break ribs 10, arranged coaxially and in a crown-ring fashion and destined to break on insertion of the dispenser cap 1 on the container 2 due to an axi al-di rectIon lowering of the second part 6 with respect to the first part 4.
• the second part 6 On an internal surface thereof and projecting internalwise in proximity of the upper end of the niche 12, the second part 6 exhibits an annular relief 26.
• This annular relief 26 exhibits an internal diameter which is slightly smaller than the maximum diameter of the crown formed by the easy- break ribs 10, and cooperates contactingly there-with in such a way as to break them when the second part 6 is first mounted on the first part 4.
• the easy- break ribs 10 have already been broken.
• a security strip 9 is connected to the support elements 11 by means of easy-break ribs 13 destined to break on first opening of the container 2 due to an axial-direction raising of the second part 6.
• the security strip 9 exhibits a projection 24 which when the dispenser cap 1 is mounted engages in an undercut 25 of the neck 3 of the container 2. The interaction between the projection 24 and the undercut 25 causes the easy-break ribs 13 to break and the security strip 9 to detach on first rotation of the second part 6
• the second part 6 exhibits, on an internal wall thereof, a plurality of elastIcal 1y-f1exi ble strips 28 arranged ci rcumferent ⁇ al 1y and cooperating with corresponding projections 27 arranged on the first part 4 in such a way as to create a sort of "noisy engagement" on each opening or closing of the dispenser cap 1
• the dispenser cap 1 is made separately in two pieces 4 and 6, while the first part 4 is made in one piece with the annular body 11 and the security strip 9.
• the two parts of the cap 1 that is, an external part constituted by the second part 6 and an internal part, constituted by the first part 4, the annular body 11 and the security strip 9) are obtained by pressing of plastic mate ⁇ al s .
• the dispenser cap 1 is formed by inserting the internal part in the external part in such a way that the annular body 11 joints in the corresponding annular niche 12 of the second part 6; subsequently the neck 3 of the container 2 is inserted into the dispenser cap 1.
• the easy-break ribs 10 which at first hold the first part 4 and the annular body 11 together, break due to the impact with the annular relief 26 of the second part 6.
• the dispenser cap 1 also simplifies the opening and closing of the container 2 without any part of the dispenser cap 1 being removed. To open it is sufficient to unscrew the second part 6 by enough to release the central mouth 7 from the wall 8; to re-close, the second part 6 is re-screwed until the central mouth 7 comes up once more agai nst the wal 1 8.
• the "noisy engaging" between the flexible elements is to signal to the user that the closing operation has been completed and that the container 2 is properly closed, so that the product does not leak accidentally, say, in a travel 11 ng bag .
• the mounting operation of the dispenser cap 1 on the neck 3 i s no more complicated than, for example, known operations for prior-art dispensing caps lacking a security device.
