2 Sheets-Sheet 1 2 Sheets-Sheet 2 SEQUENCE INDICATING MECHANISM This invention relates to a sequencing assembly which may be employed in a closure mechanism that indicates the number of openings and/or closings of a container.

The features of this invention will become more apparent in the following description read in conjunction with the figures in which:

FIG. 1 is a front elevational view of a container having an indicating closure mechanism constructed in accordance with the principles of this invention.

FIG. 2 is an exploded front elevational view, partly in cross section, of the upper portion of the closure mechanism.

FIG. 3 is a top view of an indicator for use in a preferred embodiment.

FIG. 4 is a bottom view of a moving element depicted in FIG. 2.

FIG. 5 is a front elevational view, partly in cross section, of the lower portion of a preferred form of indicating closure.

FIG. 6 is a front elevational view, partly in cross section, of a closure mechanism constructed in accordance with the principles of this invention in operating relationship with the container.

FIGS. 7 through 10 illustrate a preferred form of the novel motion transmitting mechanism constructed in accordance with the principles of this invention.

Referring now to the figures wherein like reference numerals indicate like parts, a preferred form of the sequencing assembly and its incorporation into a preferred form of an indicating closure mechanism will be described. Although throughout this description the preferred embodiment will be illustrated as, a medication dispensing device, it is obvious that many other dispensing functions such as chemical additions to manufacturing processes and the like, will find a use for an indicating closure as described in the preferred embodiment.

FIG. 1 depicts an indicating closure, denoted generally by the reference numeral 10, on a container 12. A cut out area 14 in the top of the lid 16 exposes the marking 1 SA, representing one Saturday. In this preferred embodiment the indicating closure 10 is utilized as a medication dispensing apparatus and will be described in terms of a medicine that the user must take three times daily; thus, the indication in FIG. 1 would tell the user that he has taken his first dosage on Saturday. After the user takes another dosage and, by so doing, completes one open-close cycle of the indicating closure 10, the indicator will be cycled to 2 SA and thus indicate that the second dosage for the day has been consumed.

The indicating closure 10 is composed of an upper indicating portion and a lower motive portion. The indicating portion is depicted in FIGS. 2, 3 and 4. An indicia-carrying member 18 is secured to the top of a sequenced member 20. The sequenced member 20 is releasably, rotatably secured within the lid 16 by a screw 22, a spring washer 24, and a stud into which the screw 22 is threaded. Thus, the indicia-carrying member 18 will not freely rotate but may be rotated if the frictional forces applied by the washer 24 are overcome.

Referring now to FIG. 4, the movable member 20 has a plurality of circumferentially spaced teeth 26 disposed on its underside. The teeth 26 include cam surfaces 28, which are utilized to produce the sequential indicating movement of the member 20. That motion and the specific utilization of the cam surfaces 28 will be described more fully hereinafter.

The motive portion of the closure 10 is depicted in FIGS. 5 and 7, however, teeth A, B and C in FIG. 7 should be disregarded for present purposes. An internal plate-like member 30 is adapted to be rigidly afi'ixed to a cap which may be removed from a container by a rotating movement. The internal member 30 is fitted within a recess 31 in an outer member 32 which is free to rotate with respect to both the internal member 30 and a container cap when the closure member 10 is affixed thereto. A projecting tab 34 fitted within a recessed portion 36 of the outer movable member 32 provides a stop means for limiting the rotation of the outer member 32 with respect to the inner member 30.

A spring 38 is rigidly affixed to internal member 30 by a suitable fastening means 40. The spring 38 comprises an upstanding pin 42 disposed within a second recessed portion 44 of the movable outer member 32. An upstanding projection 46 having a cam surface 48 thereon is also disposed within the recessed portion 44.

FIG. 6 illustrates the motive and indicating portions of the preferred closure 10 in assembled relationship and secured to rotatable cap 50 on a container 12. The lid 16 is rigidly secured to the outer movable element 32 by suitable screws 52. In this preferred embodiment the cap 50 is removable by counter-clockwise rotation and is secured into position by clockwise rotation with respect to the container 12. Accordingly, to seal the container 12 the lid 16 is rotated clockwise, which rotates the outer member 32 clockwise until the stop 34 on inner member 30 abuts the left edge of recess 36 as shown in FIG. 10. At that point continued clockwise rotation of the lid 16 will cause the cap member 50 to screw on to the container 12. Removal of the closure member I0.may be effected by rotating it in a counterclockwise direction. That rotation will rotate the outer closure member 32 until the stop 34 has reached the position shown in FIG. 7 at which point the lid 16, outer member 30, inner member 32, inner member 30 and consequently the cap all rotate counter-clockwise thus removing the cap 50 from container 12.

Although the cap 50 has been illustrated as a separate piece from the inner member 30, it is obvious that they could be of unitary construction. Furthermore, it should be apparent that other means than the screws 40,40 could be used to attach the inner member 30 to the cap 50 such as adhesive for one example.

In this preferred embodiment the cycling of indicia takes place during the closing of member 10. FIGS. 7 through 10 sequentially illustrate the closing of closure member 10 and also the details of the sequencing mechanism of this invention. In FIG. 7, the closure member 10 has been removed from the container 12 by rotation in a counter-clockwise direction. Thus, stop member 34 abuts the right-hand side of recess 36. Three teeth A, B and C which correspond to three of the plurality of teeth 26 present on the underside of sequenced member 20 have been superimposed over the motive portion of the closure member 10.

From the starting position in FIG. 7, all elements may be freely rotated clockwise until some degree of friction is generated between the cap member 50 and the container 12. At that point the outer member 32 begins to rotate with respect to the inner member 30. The outer member 32 and the sequenced member 20 carrying teeth A, B and C move in unison during the clockwise rotation until the intersection of cam surfaces 28 and 48 is contacted by the upstanding pin 42, as shown in FIG. 8.

- As the clockwise rotation is continued the pin 42 follows cam surface 48 and maintains the teeth A, B and C stationary with respect to the inner member 30. In FIG. 9, the furthest extent of clockwise rotation has nearly been reached as the stop 34 is very near the leftward edge of recess 36. The pin 42 is about to reach the rightward edge of upstanding member 46 whereupon the spring will retract the pin 42 to the back side of upstanding member 46.

In FIG. the clockwise rotation has been completed, the stop 34 abuts the leftward edge of recess 36. The pin 42 is now on the opposite side of upstanding member 46 from cam surface 48 and the teeth A, B and C are free to rotate counterclockwise with respect to the pin 42. Since the relative positions of teeth A, B and C and inner member 30 have been unchanged through FIGS. 8, 9 and 10 but their position with respect to the lid 16 has been altered, a new marking now appears in the window 14. If from the positions depicted in FIG. 10 the lid is now rotated counter-clockwise to open the container 12, sequenced member 20 and thus the indicia carrying member 18 will rotate with the lid because of the frictional holding spring 24 and thus maintain the same indicia in the window 14 during the opening cycle. If the container 12 were opened, the positions of the elements would be that shown in FIG. 7 except now tooth A would be in the position tooth B is depicted, tooth B would be in the position tooth C is depicted, and tooth C would have assumed a new position counter-clockwise from that shown in FIG. 7.
