Description
S PECI FI CATI ON
The present invention generally relakes to container closures. More specifically, the invention relates to a tamper evident or evidencing container closure oE the type having a dispensing oriEice and a liquid closure cap.
In recent years, a heightened emphasis has been placed upon utilization of tamper prooE oE tamper evidencing or evident closures for containers. This is particularly true for containers utilized for storage of human ingestible materials.
A known class o-E such containers employs caps or closures having dispensing orifices therethrough.
Such orifices may be used in connection with, for example, squeeze bottles or the like, and frequently include a two-section cap, a first section including a base top surface having the orifice therethrough, and a second section carrying a stopper for the orifice. In such caps the stopper carrying section is movable ~rom an orifice closing position to an orifice opening position.
The stopper carrying section may be in integral part of the closure, as shown, for example, in U.S. Patent No.
~,124,151, or may be formed as a separate but attached piece as shown, for example, in U.S. Patent Nos.
~,595,123 and ~ 1,637.
Such stopper carrying section must, of necessity, he relatively easy to open to allow the container to be used for its intended purpose. However, ease of opening of the stopper carrying section allows for possible tamperiny with the contents of the container to occur. While it is known to utilize foil or paper 2 ~
seal overlays covering the openings of the containers beneath the base top surface section, which overlays must be broken or removed prior to dispensing of the contents of the containers, such overlays are not a sufficient detriment to tampering. For example, stick-on overlays can be surreptitiously opened by steaming or the like.
Additionally, the overlays can be an undesired added expense.
It has also been known to make the stopper carryiny section physically a part of the base top surface section and to provide a tear strip portion in the connection between the two sections (see U.S. Patent Nos. 3,255,928; 3,651,992; and ~,031,108). While such tear strip portions provide an indication of tamperiny, they require that the stopper carrying sections be molded as a part of the base top surface section, an expensive procedure.
It would therefore be an advance in the art to provide a dispensing orifice type closure hav.ing means preventing opening of the stopper carryiny member which means are easily removable but which, when removed, provided indication of tamperiny, and which means further are both inexpensive and difficult to circumvent.
It would be a further advance .in the art if such a tamper evidencing or evident closure could be provided .in connection with an easily attached but substantially non-removable closure cap to container interface.
The present invention provides a tamper evident or evidencing conta:iner closure of the dispensing orifice type, wherein the c:Losure includes separate base and cap sections, the cap section including at least one tear strip connected about a closure cap between the closure cap and a skirt to indicate tampering. A pull ring positioned concentrically about the closure cap is also attached to the tear strip so that removal of the ring enables removal of the tear strip simply by pulling on the ring.
Accordingly, it i5 a principle object of the invention to provide an improved tamper indicating container closure.
It is another object of the invention to provide a tamper evident closure for a container of the dispensing orifice therethrough, wherein removal or attempted removal of the closure cap is evidenced by means of a tear strip frangibly connected to the closure cap.
It is yet another object of the invention to provide a tamper resistent container closure including a cap adapted to be received on the neck of a container with cap removal resisting means on the inner diameter of a cap skirt and on the outer diameter of the cap, which means resists removal of the cap.
Further objects, features, and advantages of the invention will be readily apparent Erom the following description of the preEerred embodiments thereof, taken in conjunction with the accompanying drawings.

In Figure l there is illustrated a closure 10 positioned on a container 12. The closure 10 includes means for evidencing tampering or attempted tampering with contents of a container 12 in accordance with principles of the invention.
With reference to Figures 1-~, it can be seen that the closure cap 10 includes separate base and cap sections 20 and 30, respectively. The base section 20 is located at and engages an opening l~ of the cont~iner 12.
2 ~ A.~ ~ rJg The cap section 30 is positioned on and about the base section 20 and the opening 14.
As is most clearly illustrated in Figure 3, the base section 20 includes a top plate member or portion 22 5 having an orifice member 23 projecting upwardly therefrom, which orifice member includes an opening 23a therethrough for dispensing of the contents of the container 12. A flange 2~ is integrally ~ormed with the plate member 22 and projects radially from an un~erside of the plate member ~2. An annular portion 26, also integrally forméd with the plate member 22, extends vertically downward from the underside of the plate member 22 and ~its within the opening 14 of the container 12, so as to abut against interiors of a wall or neck portion 15 defining -the opening 14.
As illustrated, an underside 24a of the flange 24 lays on top of A top edge 16 of the wall 15. The flange 24 extends out to the outside diameter of the neck 15. The plate member 22 does not extend to that diameter and as such, the plate member 22 and the flange 2~ form a stepped arrangement at the top sides thereof.
The cap section 30, as illustrated in F'igures 1-~, includes a lower skirt portion 32 and a hinged cap 3~. The lower skirt portion 32 is annular in shape ancl fits about the neck 15 of the container 12. The skirt portion 32 includes a circular rib or bead portion 33 that runs along the interior of the skirt 32. The rib or bead 33 engayes an underside of a rib, rim, or projection portion 17 of the neck 15 so as to retain the cap section 30 on the neck 15 o~ the container 12. As such, the cap ~J3~
section 30 is not screwed onto the neck 15, but instead is press fit thereon so that it cannot be xemoved.
- The cap section 30 also includes an inwardly extend~ng wall 32a at a top edge of the skirt 32 in the sh~r,f of a flattened ring. It can be appreciated from the cross-sectional view of Figure 3, that the wall 32a of cap section 30 also serves to retain the base section 20 and cap section 30 on the neck 15. It can be seen that the cap ~ is hingedly attached to t~e s~irt portion 32 by means of a bridging hinge 40 formed of material that extends between the skirt 32 and the cap 34 and that has appropriately formed crease 42 therealong. The crease 42 permits the cap 34 to be moved between a closed position as illustrated in Figure 3, to an open position as illustrated in Figure 8.
The cap 34 further includes a stop member 50 formed on an underside thereof that engages the opening 23a of the orifice member 23 when the cap 34 is in its closed position. In a preferred embodiment, the stop member and orifice member 23 are designed for frictional engagement therebe-tween to secure the cap 34 in its closed position. ~lowever, other means are available for securing the cap 34 in its closed position, as will become apparent below.
At the same time that the cap 34 and skirt 32 are formed, a pair of tear strips 60 are formed such that they connect between a lower edye 62 of the cap 3~ and an insi~e edge 6~ of the wall 32a oE the skirt 32, on opposite sides of the cap 3~. The tear strips 60 do not encircle the entire cap 34. Instead, the tear strips 60 on a fxont side o~ the cap 34 are separated by a ~istance ~ ~ 2 ~ '~ a ~J
sufficient to permit ~ormation or molding of a lift tab 70 for moving the cap 34 between its open and closed positions. On ?. back side of the cap 34, the tear strips 60 are separated by a distance sufficient to permit formation o.r. '~he hinged bridge 40. Additionally, on opposite sidei of the hinged bridge 40, there are formed slots 80 that isolate the hinge ~0 from the tearing action of the tear strips 60 so that the integrity of the hinge 40 is not destroyed when the tear strips 60 are removed.
As is most clearly illustrated in Figure 5, each of the tear strips 60 includes one edge connected to the lower edge 62 of the cap 34 and another edge connected to an inside edge 64 of the inwardly extending ring 32a of the skirt 32. The edges are frangible so that the tear strip 60 can be easily removed, but so that they cannot again be replaced. These frangible edges can be created by perforations or sufficient thinning of the material forming the connecting edges.
Also included in the cap section 30 is a pull ring 90 utilized to pull at the tear strips 60 so that the tear strips 60 can be removed. This ring 90 is concentrically positioned about the cap 3~ but is not connected thereto. This is clearly illustrated in Fiyure 3.
The pull ring 90 is formed so as to be poiitioned at the height of the top of the cap 3~ and includes ~wo downwardly angled bridge members 92 that connect between the pull ring 90 and the tear strips 60.
It can be appreciated, that when the tear strips 60 are to be removed, one simply grasps the pull ring 90 and pulls upwardly relative to the cap 34, without grasping the cap 34, until the ~ear strips 60 are removed or otherwise torn away. The pull ring 90 will cause the tear strips 60 to commer e tearing at the hinged side of the cap 3~ and then 'o proceed tearing toward the lift tab 70 side of the cap 3~.
Once the tear strips 60 have been removed, the cap section 30 will appear from a to view as is illustrated in Figure 6. In the top side of the flattened portion ring 32a of the skirt 32 is fully visible. Moreover, the portions of the top side of the base section 20 previously covered by the tear strips is now visible. At this point, the cap 3~ can be freely moved between opened and closed positions. It can be appreciated, however, that without removal o~ the tear strips 60, the closure cap 34 is precluded from being moved to its open position because it would be secured to the skirt 32.
In Figure 9, there are illustrated additional princ:iples o~ the invention.
It can be appreciated that because the cap and base sections 30 and 20, respectively, are separate].y ~ormed, it can be appreciated that it is possible that the cap section 30 can become rotationally misaliyned relative to the base section 20. Th.is would not be a problem if the orifice member 23 were centrally located on the base section 20. However, if the orifice member 23 is not centrally loca-tecl on the base section 20, then the stopper member 50 and the orifice member 23 can become so misaligned that they no longer engage one another.
~2~2 To maintain the cap and base sections 30 and 20, respectively, in rotational alignment, there can be provided a detent member 100 in the skirt 32 that projects into an appropriately 'o~med indentation or openiny 102 in the flange 2~ of the base section 20, as illustrated in Figure 9. Of course, there are a myriad of other schemes that can be employed to accomplish alignment between the cap and base sections 30 and 20, respectively.
Additionally, other means for securing the cap 3~ in its closed position are contemplated. For example, the interior of the annular wall 35 of the cap can contain a notch 104 that is engaged by a projection 106 that extends from the base section 20. Similarly, the orifice member 23 can contain a rib 108 or other detents that extend inwardly and engage mating notches 110 in the stopper. Many other schemes are also possible.
With respect to the materials of which the closure 10 is made, in the preferred embodiment, the cap and base sections are formed of a thermo-plastic material that is easily molded. However, thermoset plastics and other materials are also conkemplated.
While a preferred embodiment has been shown, modifications and changes may become apparent to those skilled in the art which shall fall within the spirit and scope of the invention. It is intended that such modi~ications and changes be covered by the atkached claims.

In Figure l there is illustrated a closure 10 positioned on a container 12. The closure 10 includes means for evidencing tampering or attempted tampering with contents of a container 12 in accordance with principles of the invention.
With reference to Figures 1-~, it can be seen that the closure cap 10 includes separate base and cap sections 20 and 30, respectively. The base section 20 is located at and engages an opening l~ of the cont~iner 12.
2 ~ A.~ ~ rJg The cap section 30 is positioned on and about the base section 20 and the opening 14.
As is most clearly illustrated in Figure 3, the base section 20 includes a top plate member or portion 22 5 having an orifice member 23 projecting upwardly therefrom, which orifice member includes an opening 23a therethrough for dispensing of the contents of the container 12. A flange 2~ is integrally ~ormed with the plate member 22 and projects radially from an un~erside of the plate member ~2. An annular portion 26, also integrally forméd with the plate member 22, extends vertically downward from the underside of the plate member 22 and ~its within the opening 14 of the container 12, so as to abut against interiors of a wall or neck portion 15 defining -the opening 14.
As illustrated, an underside 24a of the flange 24 lays on top of A top edge 16 of the wall 15. The flange 24 extends out to the outside diameter of the neck 15. The plate member 22 does not extend to that diameter and as such, the plate member 22 and the flange 2~ form a stepped arrangement at the top sides thereof.
The cap section 30, as illustrated in F'igures 1-~, includes a lower skirt portion 32 and a hinged cap 3~. The lower skirt portion 32 is annular in shape ancl fits about the neck 15 of the container 12. The skirt portion 32 includes a circular rib or bead portion 33 that runs along the interior of the skirt 32. The rib or bead 33 engayes an underside of a rib, rim, or projection portion 17 of the neck 15 so as to retain the cap section 30 on the neck 15 o~ the container 12. As such, the cap ~J3~
section 30 is not screwed onto the neck 15, but instead is press fit thereon so that it cannot be xemoved.
- The cap section 30 also includes an inwardly extend~ng wall 32a at a top edge of the skirt 32 in the sh~r,f of a flattened ring. It can be appreciated from the cross-sectional view of Figure 3, that the wall 32a of cap section 30 also serves to retain the base section 20 and cap section 30 on the neck 15. It can be seen that the cap ~ is hingedly attached to t~e s~irt portion 32 by means of a bridging hinge 40 formed of material that extends between the skirt 32 and the cap 34 and that has appropriately formed crease 42 therealong. The crease 42 permits the cap 34 to be moved between a closed position as illustrated in Figure 3, to an open position as illustrated in Figure 8.
The cap 34 further includes a stop member 50 formed on an underside thereof that engages the opening 23a of the orifice member 23 when the cap 34 is in its closed position. In a preferred embodiment, the stop member and orifice member 23 are designed for frictional engagement therebe-tween to secure the cap 34 in its closed position. ~lowever, other means are available for securing the cap 34 in its closed position, as will become apparent below.
At the same time that the cap 34 and skirt 32 are formed, a pair of tear strips 60 are formed such that they connect between a lower edye 62 of the cap 3~ and an insi~e edge 6~ of the wall 32a oE the skirt 32, on opposite sides of the cap 3~. The tear strips 60 do not encircle the entire cap 34. Instead, the tear strips 60 on a fxont side o~ the cap 34 are separated by a ~istance ~ ~ 2 ~ '~ a ~J
sufficient to permit ~ormation or molding of a lift tab 70 for moving the cap 34 between its open and closed positions. On ?. back side of the cap 34, the tear strips 60 are separated by a distance sufficient to permit formation o.r. '~he hinged bridge 40. Additionally, on opposite sidei of the hinged bridge 40, there are formed slots 80 that isolate the hinge ~0 from the tearing action of the tear strips 60 so that the integrity of the hinge 40 is not destroyed when the tear strips 60 are removed.
As is most clearly illustrated in Figure 5, each of the tear strips 60 includes one edge connected to the lower edge 62 of the cap 34 and another edge connected to an inside edge 64 of the inwardly extending ring 32a of the skirt 32. The edges are frangible so that the tear strip 60 can be easily removed, but so that they cannot again be replaced. These frangible edges can be created by perforations or sufficient thinning of the material forming the connecting edges.
Also included in the cap section 30 is a pull ring 90 utilized to pull at the tear strips 60 so that the tear strips 60 can be removed. This ring 90 is concentrically positioned about the cap 3~ but is not connected thereto. This is clearly illustrated in Fiyure 3.
The pull ring 90 is formed so as to be poiitioned at the height of the top of the cap 3~ and includes ~wo downwardly angled bridge members 92 that connect between the pull ring 90 and the tear strips 60.
It can be appreciated, that when the tear strips 60 are to be removed, one simply grasps the pull ring 90 and pulls upwardly relative to the cap 34, without grasping the cap 34, until the ~ear strips 60 are removed or otherwise torn away. The pull ring 90 will cause the tear strips 60 to commer e tearing at the hinged side of the cap 3~ and then 'o proceed tearing toward the lift tab 70 side of the cap 3~.
Once the tear strips 60 have been removed, the cap section 30 will appear from a to view as is illustrated in Figure 6. In the top side of the flattened portion ring 32a of the skirt 32 is fully visible. Moreover, the portions of the top side of the base section 20 previously covered by the tear strips is now visible. At this point, the cap 3~ can be freely moved between opened and closed positions. It can be appreciated, however, that without removal o~ the tear strips 60, the closure cap 34 is precluded from being moved to its open position because it would be secured to the skirt 32.
In Figure 9, there are illustrated additional princ:iples o~ the invention.
It can be appreciated that because the cap and base sections 30 and 20, respectively, are separate].y ~ormed, it can be appreciated that it is possible that the cap section 30 can become rotationally misaliyned relative to the base section 20. Th.is would not be a problem if the orifice member 23 were centrally located on the base section 20. However, if the orifice member 23 is not centrally loca-tecl on the base section 20, then the stopper member 50 and the orifice member 23 can become so misaligned that they no longer engage one another.
~2~2 To maintain the cap and base sections 30 and 20, respectively, in rotational alignment, there can be provided a detent member 100 in the skirt 32 that projects into an appropriately 'o~med indentation or openiny 102 in the flange 2~ of the base section 20, as illustrated in Figure 9. Of course, there are a myriad of other schemes that can be employed to accomplish alignment between the cap and base sections 30 and 20, respectively.
Additionally, other means for securing the cap 3~ in its closed position are contemplated. For example, the interior of the annular wall 35 of the cap can contain a notch 104 that is engaged by a projection 106 that extends from the base section 20. Similarly, the orifice member 23 can contain a rib 108 or other detents that extend inwardly and engage mating notches 110 in the stopper. Many other schemes are also possible.
With respect to the materials of which the closure 10 is made, in the preferred embodiment, the cap and base sections are formed of a thermo-plastic material that is easily molded. However, thermoset plastics and other materials are also conkemplated.
While a preferred embodiment has been shown, modifications and changes may become apparent to those skilled in the art which shall fall within the spirit and scope of the invention. It is intended that such modi~ications and changes be covered by the atkached claims.
