Definitions

  • This invention relates generally to container closures of tamper-indicating type and containers provided with such closures.
  • US-A-2 939 597 there is described a container closure for providing tamper-indication.
  • This closure has a closure member defining a container closure expanse and adapted for rotative first and second movements for closing and opening the container with at least one protrusion depending from the top of the closure member for engagement with a tamper-indicating element and radially offset from the rotation center of the first and second movements.
  • the tamper-indicating element of this container closure is retained within the closure member and at least one protrusion is inaccessible through the closing expanse and said closure affording visibility therethrough of the tamper-indicating element which has a higher frictional adherence to the container than to the closure member.
  • the cooperating parts such as the protrusions and ratchet teeth, move relatively into a position in which the closure member has been advanced a part of the turn while a locking member remains stationary. Therefore the previously hidden printed indication of the tamper-indicating element will become visible. As the locking member cannot be removed from the closure member the tamper-indicating element will remain in such a position that the printed indication is visible even if the closure member is applied again to reseal the container.
  • This known tamper-indicating element uses a printed indication in order to indicate that the closure member has already been opened.
  • teltale indication i.e., a tamper-indicating means or a readily discernible characteristic indicative of tampering, such as a signal that some person has previously attempted to gain access to the container contents.
  • this approach can be generalized as placing a tamper-indicating member in the path of access to a container to indicate tampering by discernible change.
  • tamper-indicating means one finds in the prior art approaches elements which evidence color change, which mechanically present literal messages, and which are ruptured or torn upon the occurrence of tampering.
  • the color change devices may be considered less than desirable as requiring ambient-sensitive constituents and measures for sealing same from ambient environment.
  • the mechanical devices providing literal indication i.e., the words "closed” or “open” (see for example US-A-2 939 597), are less than desirable as they are inherently complex and customized.
  • the rupturing and tearing practice offers the best potential for desired simplicity in solution.
  • Prior art tamper-indicating means may also be categorized in respect of the relative location thereof to the container access port.
  • the tamper-indicating means are located directly at the access port and wherein the tamper-indicating means are otherwise located in the path of access to the container.
  • tamper-indicating means directly span the access opening, e.g., are secured across the mouths of jars.
  • the tamper-indicating means are located in container wrappers, within plastic heat shrunk about the capped jar, etc.
  • the effective location for a tamper indicator is directly at the access port, since wrappers, heat shrunk plastic sleeves and like tamper-indicating means outside the container may be removed and the remaining capped container remain without tamper indication.
  • prior art tamper indication may be categorized as of type wherein the tamper-indicating means directly at the access opening is closure member activated or not.
  • the former category reverse sense (opening) movement of the closure member or closure cap brings some element into tearing relation with the tamper-indicating means.
  • tamper-indicating means is unaffected by closure member removal.
  • closure member activated case affords greater security.
  • US-A-2,131,774 and US-A-2,131,775 are considered to disclose tamper-indicating containers incorporating the desired of the foregoing categories of tamper indication.
  • the tamper-indicating element is simple rupturable sheet material. The element is located directly at the container mouth opening and is cap-activated. In accommodating this operative selection of features, however, these disclosed tamper-indicating containers have vulnerability, recognized expressly in the patents, to direct tampering with the tamper-indicating element.
  • the Waring US-A-2 131774 practice is to provide a cap in the form of a hollow cylinder having a skirt depending from the cap top and interiorly threaded to receive the jar neck.
  • the cap top is centrally open and prongs are formed in the plane of the cap extending into the central opening.
  • the tamper-indicating element is nested in the cap interior and suitably secured therein.
  • the cap with its nested tamper-indicating element is then rotated into secured relation with the jar. Now the prongs are bent out of the plane of the cap top and into puncturing relation with the tamper-indicating element, remaining accessible through the open cap top.
  • the tamper-indicating element is secured to the cap for movement therewith, the cap again having its top centrally open.
  • a liner is stapled, stitched or glued to the tamper-indicating element.
  • a frictional undersurface of the liner is compressed onto the jar neck by friction therebetween.
  • the cap and tamper-indicating element rotate initially relative to the liner and staple, whereby the staple ruptures the tamper-indicating element.
  • the limitation of the US-A-2 131 774 practice is again present, i.e., the staple is accessible at all times through the open cap center.
  • cap liners with the cap during cap shipment and cap application to containers is a present industry practice, as is shown, for example, in US-A-3,819,460 and 3,917,100.
  • a circumferential groove is formed in the cap immediately beneath the cap top panel above the cap threads.
  • the liner is forced into the cap and nests in the retention groove.
  • the liner includes a compressible layer which is said to be displaced radially outwardly of the liner into sealing relation with the groove wall as the cap is threaded upon a container.
  • tamper indication is not involved and there is no anchoring of the liners to the container mouth, as by adhesive or other bond.
  • This invention has as its primary object the provision of improved tamper indication for containers of the capped type.
  • the invention has as a further object the accommodation of the above-noted practice selections and existing practices in the related industries.
  • the present invention has as another object the provision of tamper indication systems wherein the alternative user preference is accommodated in both of its requirements.
  • a container closure for providing tamper indication having a closure member defining a container closure expanse and adapted for rotative first and second movements for closing and opening the container with at least one protrusion depending from the top of the closure member for engagement with a tamper-indicating element and radially offset from the rotation center of such first and second movement; said tamper-indicating element being retained within the closure member, said at least one protrusion being inaccessible through said closing expanse and said closure affording visibility therethrough of the tamper-indicating element which has a higher frictionat adherence to the container than to the closure member (as known from US-A-2,939,597), whereby the container closure is characterized in that at least one protrusion is designed for selectively tearing said tamper-indicating element during said second movement.
  • the tamper-indicating element may be in the form of a simple paper seal closing the mouth, and the closure may be a see-through cap releasably securable to the container and circumscribing its mouth and the tamper-indicating element when secured to the container.
  • the cap includes one or more puncturing elements in form of protrusions interiorly of the cap for travel with the cap.
  • the tamper-indicating element is arranged in captive relation to the puncturing element prior to assembly of the cap with the container. As the cap is rotated in securement with the container, the tamper-indicating element becomes secured to the container mouth as it engages same, for example, through contact activation of a sealant on the container or jar mouth. Reverse sense opening movement of the cap is accompanied by visible rupturing and tearing of the tamper-indicating element.
  • the puncturing element may take the form of one or more knife-like tines depending from the cap upper interior surface and non- deflectable relative thereto.
  • the cap is made of transparent material such that the condition of the tamper-indicating element may be viewed constantly after the initial assembly juncture and to the point of consumer sale.
  • the cap tines have a tamper-indicating wafer applied thereto and the tines are then blunted upon the tamper-indicating wafer undersurface.
  • a second wafer is now adhesively secured to the tamper-indicating wafer and, since the second wafer is unaffected by the tines when the tamper-indicating wafer is ruptured, the second wafer can maintain the jar sealed and its contents unaffected by tamper-indicating wafer ruptured parts.
  • a further tamper-indicating element has a compressible layer, such as foam, in which the tines are captive.
  • the preferred tamper-indicating element is a laminate inclusive of such compressible layer and an underlayer which is both effective to blunt the tines in fully captured relation in the compressible layer and to serve as a jar sealing layer.
  • a foil overlayer may also be included.
  • the cap may include means for distributing force applied to the tamper-indicating element to its periphery, thereby lessening the likelihood of tine rupture of the tamper-indicating element in movement of the cap into initial securement with a jar.
  • the force distributing means may also serve as a cap reseal for a jar upon removal of the tamper-indicating element after initial jar opening.
  • the invention further encompasses an overcap for the closure cap to defeat malicious activations of the tamper-indication element.
  • a further embodiment of the invention includes, in addition to the tines, means within the cap for engaging the tamper-indicating element selectively subsequent to its activation on cap opening movement, both to forcibly break the sealing bond between the tamper-indicating laminate and container and to retain the tamper-indicating laminate with the cap.
  • the tamper-indicating laminate is secured to the container mouth, as by induction heating, and the tamper-indicating laminate is so structured as to maintain its integrity as it is forcibly separated from such securement in the course of cap opening movement.
  • the invention provides a container in the form of a vessel comprising the customary neck terminating in a container mouth and defining surface extent circumscribing the mouth and inclusive of container sealing surface and the neck has the typical threads for closure member securing thereon.
  • the container surface extent is adapted for engaging the tamper-indicating element and is configured to effect first and second different engagements therewith respectively in the course of the first and second sense movements.
  • the container permits the tamper-indicating element to be moved into closure relation with the sealing surface in first sense closure movement and to be selectively positively restrained from movement relative to the mouth in the initial phase of the second sense closure member movement without need for an adhesive layer or other bonding agent between the container neck and the tamper-indicating element.
  • closure or cap 10 includes a closure member 12 having depending skirt 12a and interior threading 14 with lower opening 16.
  • the cap defines closing expanse comprising skirt 12a and the undersurface 12b of cap 10, for registry with the neck and mouth of a jar or like container having an access opening for obtaining its contents.
  • cap 10 Interiorly of such closing expanse, cap 10 includes one or more tines, three being shown as 18a, 18b and 18c, comprising puncturing and tearing or rupturing elements spaced at equal angles.
  • Each tine may be formed integrally with cap 10, e.g., is molded therewith, and is rigid, such that it is not readily deflectable relative to cap undersurface 12b.
  • the tines may be parts of an insert to cap 10, which is secured therein for movement therewith. Based upon its secured relation to cap 10, each tine travels with the cap in the course of its first sense (clockwise) movement into releasably secured relation with the jar neck and also in the course of second opposite sense (counterclockwise) cap movement relative to the jar for release from such secured relation therewith.
  • Cap 10 is formed of optically clear plastics of butyrate, acetate, nylon, lucite and plexiglass and the like.
  • the jar for use with cap 10 is preferably made of glasser thermoplastics such as will provide a barrier to covert penetration, such as by use of a hypodermic needle. High impact styrene is suitable.
  • tine 18c shown in Figs. 3 and 4
  • same includes a vertically extending radially outward wall 20, terminating in inverse V-shaped groove or rupturing channel 22, bounded by surfaces 24a and 24b, each forming angle A (forty-five degrees) with the central vertical plane of tine (axis 26 on Figure 3).
  • the channel extends radially inwardly and upwardly to interior wall 28 at angle B (thirty degrees).
  • cap 30 has skirt 32, interior threading 34, interior cap undersurface 30a and supports tines 36a, 36b and 36c, extending in the direction of lower opening 38.
  • each of tines 18a-c and 36a-c is radially offset from the center of the rotative movements of caps 10 and 30 and that each extends generally parallel to the axis of the hollow cylindrical cap.
  • Each tine is also disposed radially of the rotation center, thus having extent generally radial to provide a frontal expanse for rupturing or tearing of a member penetrated thereby.
  • tines 36a-c will be seen to involve an asymmetry about axis 40.
  • V-shaped configuration is defined by tapered sidewalls 42 and 44, the former starting its taper at location 42a, higher than that 44a for the latter. Both taper at angle C (thirty degrees) and incline radially inwardly upwardly from outward wall 45 to interior wall 46 at angle D (thirty degrees).
  • the asymmetry gives rise to a preferential directional deformation oftines as indicated for tine 36c in Fig. 10 upon assembly as now discussed.
  • tamper indication means 48 is a generally flat disk which may be comprised of a layer of foam alone, e.g., styrene based plastic foam.
  • Assembly tool 50 (Fig. 7) includes a backing member 52, being rigid in practice under present discussion, e.g., a metal cylinder, for receiving layer means 48 on its upper surface 52a and is movable in direction E for inserting layer means 48 into opening 38 of cap 30.
  • Fig. 10 shows the assembly resulting from such insertion practice with a rigid backing member.
  • the entirety of tine 36c is situated in layer means 48, with end portion 36c-1 of the tine positioned in spaced relation to layer means undersurface and with thetine defining a generally hooked shape at its end portion 36c-1, such hook being in retentive relation to layer means 48 and extending in direction F, i.e., the direction of opening movement (counterclockwise rotation) of cap 30.
  • the tine is disposed to enhance tearing of layer means 48 in the course of opening movement of cap 30 and accordingly is adapted to heighten tamper indication.
  • tine 36c is so deformed that reuse of the cap by a would-be tamperer is negated.
  • Layer means 48 may carry on its undersurface a marginal ring 53 of contact-activated adhesive, or same may be applied to the jar mouth, whereby the Fig. 10 assembly has jar securement. With tine 36c spaced from such undersurface, ruptured fragments of layer means 48 may be removed upon container opening without entering the container.
  • Backing member 52 may, if desired, be a compressible member, e.g., rubber, to reach the assembly shown in Fig. 11.
  • a major extent of tine 36c is situated in layer means 48 (more than half of its vertical extent), thus enhancing tamper-indicating element rupture. Retention is effected by the remnant of tine 36c exteriorly situated with respect to layer means 48.
  • the tamper indication means 48 has been discussed as constituted by foam for layer means 48, the invention contemplates various other tamper-indication means, some of which are seen in Figs. 12, 14 and 16.
  • the tamper-indication means comprises foam layer 54 in assembly with overlayer 56 of metal foil, defining laminate 58.
  • Practice of the Fig. 10 method i.e., rigid backing member, gives rise to the assembly of Fig. 13, wherein tine 36c penetrates and is thus situated in both layers of the laminate.
  • the laminate 60 comprises foam layer 62 and underlayer 64 constituting a container access port seal, e.g., glassine or like sealing layer.
  • a container access port seal e.g., glassine or like sealing layer.

  • tine 36c penetrates the metal foil layer 70 and foam layer 68 and is spacedly disposed relative to the glassine underlayer 72, which is securable to the jar mouth as above discussed.
  • Tines may take the further configuration shown in Figs. 18 and 19.
  • tine 74 is symmetrical about axis 76 and defines piercing apex 78 inclined radially inwardly upwardly between end walls 80 and 82.
  • the upper surfaces of container access port sealing layers of glassine or like dense paper are provided with coloration, e.g., bright red, and the foam layers are of offset color, e.g., white, whereby a vivid tamper indication is provided as the closure member is rotated in the opening direction.

  • foam layers are of offset color, e.g., white
  • surety of tamper indication is effected.

  • the tine rollover or staking step has benefit in enhancing the tearing thereof. Further, the step places the preassembly attained thereby in such posture that it may now receive an underlayer, as part of the cap as manufactured, having its integrity unaffected by activation of the tamper-indication means. Thus, with the tine ends now blunted and not having their prior puncturing and tearing capability below the tamper-indication means, jar mouth or container access port sealing layer 124 is isolated from the tines. Referring to Fig.
  • an adhesive 126 may be applied either to the mouth of container 128 or to the undersurface of layer 124, such that, upon securement of closure 122 to the jar by engagement of cap threads 116 with container neck threads 130, layer 124 becomes secured to the container and hence teltale 120 is rendered fixed relative to the container. Gripping of closure 122 and counterclockwise rotation thereof effects a tearing of teltale 120 and indicates initial opening of the container.

The tamper-indicating element is now removed from cap 312, i.e., by peeling same from tines 316.
  • the tamper-indicating member-less cap is seen in Fig. 36, which also shows the reseal capability of tamper-indicating element protection means 328.
  • flat surface 334 of end portion 332 is in sealed relation with surface 338 of container 318, desirably in flat horizontal disposition, generally parallel to top panel 312c, as indicated in Fig. 36.
  • container 410 includes cap or closure member 412 of see-through plastic material having skirt 414 with interior threads 416.
  • a circumferential bead 418 projects inwardly from skirt 414 with threads 416, but is fully horizontally disposed, and defines with undersurface 412a of the cap top 412b a recess or groove 420.
  • Tines 422a, 422b and 422c (Fig. 5) are movable with cap 412 in its rotative movement.
  • Each tine tapers to piercing apex as shown at 422a-1 and 422b-1 in Fig. 37 and is preferably of length below undersurface 418a less than the vertical run of recess 420.
  • the preferred structure of tamper-indicating assembly 424 is a laminate, as is seen in the enlarged view of Fig. 40.
  • the laminate includes an uppermost compressible layer 426 of material, e.g., open cell styrofoam, which is rupturable and tearable by tines 422a ⁇ 422c. This layer is desirably from 762 pm to 889 pm mils in thickness.
  • a printed pattern is applied to top surface 426a of layer 426.
  • a strip pattern adhesive 427 is applied to stiffening layer 428 for securement thereof to the undersurface of layer 426.
  • This strip pattern adhesive layer is comprised of a pressure-sensitive hot melt, and may be about 25.4 pm in thickness.
  • Assembly 424 is cylindrical or disk-shaped and the individual strips, one identified at 427a, of the pattern adhesive layer are spaced from other strips and extend chordally of the cylinder.
  • Stiffening layer 428 is comprised of a clear K-resin and is preferably from 101.6 um to 254 pm.
  • the above- mentioned pressure-sensitive adhesive bonds layer 428 to tamper-indicating layer 430, which is a paper of about 25.4 um in thickness.
  • Bottom layer 432 is a 25.4 pm aluminum foil which is coated with general purpose polyethylene or Surlyn (trademark) etc. Color and pattern features are significant, both from a security and control viewpoint and tamper indication viewpoint.
  • the printed pattern on surface 426a is desirably a thin line green imprinting to impart an anti-counterfeit character to tamper-indicating assembly 424.
  • Layer 426 is preferably white foam and the coloration of tamper-indicating paper layer 430 is desirably red on its surface facing clear stiffening layer 428.
  • jar 434 is partially shown and has neck 436 with exterior threads 438.
  • a layer 440 of controlled release type adhesive may be applied to the mouth of neck 436.
  • cap 412 is inverted from its Fig. 37 orientation and tamper-indicating assembly 424 is forced against surface 412a of top panel 412 by a rigid, e.g., metal, backing member applied to layer 432 of assembly 424.
  • Layer 426 is punctured by the tines and the tines are deformed in the foam, effecting retention of assembly 424 by the tines.
  • Fig. 38 wherein tamper-indicating assembly 424 is nested in recess 420 and is held by the tines in preselected spaced vertical relation to bead 418, for purposes below discussed.
  • cap 412 is fully threaded in container closing sense (full clockwise movement as in Fig. 41).
  • Layer 432 (Fig. 40) of tamper-indicating assembly 424 is secured to the mouth of neck 436 by adhesive layer 440 and the tamper-indicating assembly is thus anchored to both cap 412 and jar 434.
  • layer 432 is polyethylene-coated aluminum, or other compatible coating as above discussed, the latter anchoring is done preferably by induction heating of the aluminum foil, which directly bonds the coating to the container neck, without need for a separate adhesive.
  • a measure of counterclockwise (opening sense) rotation of cap 412 can occur prior to any confrontational engagement of bead 418 with layer 432 and hence prior to any discontinuance of the anchoring of assembly 424 to the mouth of neck 436.
  • tines 422a, 422b and 422c tear through foam layer 426, giving rise to a revealing of tamper-indicating layer 430 in areas 442, 444 and 446 as shown in Fig. 42, and the presentation of the vivid red layer 430 through the white foam against the green line background atop foam layer 426.
  • a tamper-indicating assembly design consideration which assists in the realization of the features discussed immediately above, is the character of layer 428 of tamper-indicating assembly 424.
  • This layer is effective to withstand the camming force applied to the tamper-indicating assembly by bead 418 in the course of its release from jar 434, while at the same time retaining the cylindrical geometric configuration of assembly 424.
  • assembly 424 will thus be seen to have an anti-counterfeit imprint atop a tine securement layer (layer 426), a layer for maintenance of structural integrity (layer 428), a tamper-indicating layer (layer430) and sealing and reseal layer (layer432).
  • cap 412 will be seen to have plural and successively operative means for retention of tamper-indicating assembly 424.
  • Tines 422a-422c represent first means for tamper-indicating assembly retention, being imbedded in layer 426 upon cap and tamper-indicating assembly. Bead 418 is inactive until such time as tines 422a-422c have ruptured layer 426 and lost retentive relation therewith, but follows tamper-indicating assembly 424 to retentively and con- tinuingly engage the same following tamper-indicating activation.
  • the tamper-indicating means can be in the multilayer form shown as element 320 (Fig. 32) and in other tamper-indicating configuration, for example, running from a single paper layer disrupted by the tines to other multilayer structures, e.g., wherein a foam layer is in immediate juxtaposition to the cap top panel and is supported by an encapsulated aluminum layer, the latter being in present commercial usage. Where the foam layer is opaque, the aluminum layer, or other underlying tamper-indicating means is seen in its portions in registry with the translucent tines, when inactivated, and is highly visible upon activation.
  • tamper-indicating structure could see an upper paper layer, a foam layer, a lower paper layer and a lowermost layer comprising Surlan (trademark) coated aluminum foil. While engagement of the tines and tamper-indicating structure has been shown as involving penetration of the tamper-indicating means by the tines, the invention contemplates also a surface joinder of the tines and tamper-indicating means, e.g., the tines having surface engaging the tamper-indicating upper surface and such surfaces being heat bonded together. Further, while the depicted embodiments employ rotative closures having internal threads, the invention requires only that the closures be rotative for tamper-indicating activation.
  • tamper-indicating assembly 424 would be to form the tamper indication atop the stiffening layer, as by coloration on the upper surface thereof.
  • the stiffening layer may now be constituted of opaque material, such as hardboard, since the tamper indication is not required to be seen therethrough as in the first discussed embodiment, wherein the stiffening layer of K-resin has see-through character.
  • FIG. 46 through 48 another embodiment of the invention involves a tamper- indicative container having a vessel with facility for non-adhesive engagement with the container closure member.
  • Vessel 610 includes a neck 612 bearing suitable cap securement threads 614 on its exterior surface and providing an access channel between the vessel mouth and vessel interior compartment 616.
  • the vessel defines surface extent circumscribing the mouth, inclusive of peripheral teeth 618, a flat expanse 620 and vessel sealing surface 622.
  • sealing surface 622 directly borders the mouth and is a flat annulus (Fig. 46).
  • Flat expanse 620 is also an annulus, contiguous with sealing surface 622 and vertically recessed therebelow by dimension B. Expanse 620 extends to the root, i.e., the lower end of inclined surface 618b, of teeth 618.
  • Each of teeth 618 also has an outer vertical side 618a, leading to a tooth peak, an interior side 618c which is substantially vertically disposed and another interior side 618d, which is inclined to the horizontal. In clockwise sense in Fig.
  • side 618c is clockwise leading, i.e., is spatially ahead in the sense that one o'clock is spatially ahead of twelve o'clock, and side 618d is clockwise lagging, sides 618c and 618d of each tooth intersecting at such tooth peak and otherwise throughout the length of inclined surface 618b.
  • Teeth 618 witt be seen to rise vertically above sealing surface 622 by a dimension equal to the difference between A and B and accordingly the teeth can penetrate a layer applied to surface extent 618-620-622 to the depth therein equal to such difference dimension when the layer is in sealed relation with sealing surface extent 622.
  • the full radial dimension of surface extent 618-620-622 is noted as F, equal sub- dimensions C, D and E applying to the radial dimension of sealing surface 622, recessed expanse 620 and teeth 618.
  • a preferred tamper-indicating element for use in practice includes a compressible inner layer of open cell foam, an upper layer of metal foil and a lower layer of closed cell foam, suitable for sealing the vessel to which it is applied.
  • the tamper-indicating element is nested in cap as above discussed in connection with Figs. 5-7.
  • cap With assembled tamper-indicating element, is threaded onto vessel 610 at the point of initial closing of the container after content filling thereof, layer rides relatively freely over ramp-like surfaces 618d of vessel 610 and ultimately, closure between cap and vessel 610 is such that layer abuts sealing surface 622 to effect sealing of the vessel.
  • the teeth take up residence in layer in such manner that the tamper-indicating element will be positively restrained from movement relative to vessel 610 in the initial course of opening movement (counterclockwise) of cap. There results consequently the required relative movement of the cap tines with respect to the tamper-indicating element and visible rupturing thereof.
  • the foam is torn through, exposing any desired tamper indicia placed on the upper surface of the closed cell layer of the tamper-indicating element.
  • the peaks of teeth 618 could be radially outward of the roots thereof and at the same vertical elevation as the roots to effect like different engagement between the vessel and the tamper-indicating element in respective different sense movements of the closure member.
