Definitions

  • the invention is in the general field of packaging, and in particular, in the field of packaging food products in hermetically sealed containers.
  • Many food products and liquors are commonly packaged in glass containers that are hermetically sealed by means of turn olf type closure caps.
  • tamper-proof closures have been developed.
  • Such tamper-proof closures of one type or another are extensively used in the packaging of hard liquor, such as whiskey and gin.
  • the use of such tamper-proof closures is gaining acceptance in the packaging of such products as catsup, sauces and syrups, and may shortly extend into the packaging of many other food and even non-food products.
  • the invention provides new and novel improvements in a specific type of tamper-proof, turn-off container closure construction that is in widespread use.
  • the prior art Tamper-proof packages of the specific type under con sideration include a container, usually made of glass, such as a bottle or jar, and a turn-01f type metallic closure cap that is in engagement with inclined surfaces, such as the surfaces of threads on the container finish portion adjacent the container mouth opening.
  • the cap includes a separable ring at the lower end of the skirt which is connected to the skirt by circumferentially spaced frangible bridges.
  • Cooperating means are provided on the separable ring and container finish which provide detents to prevent the ring from rotating when the cap is turned for removal. The turning of the cap creates shearing forces acting on the frangible bridges resulting in the rupture of the bridges and the separation of the ring from the upper cap portion.
  • a customer opens either one of the types of package immediately above described, he may have some indication as to whether the package had been priorly opened. If the package was priorly unopened, it will require a relatively high turning force to fracture the frangible bridges between the separable ring and the upper cap portion. The bridges may be heard to snap and the sudden release in pressure may be felt by the fingers. In the event that the package was priorly opened, there will be no audible signal such as caused 'by the breaking of the frangible bridges, nor will there be the sudden lessening of the turning force as occurs immediately following the breaking of the bridges. The lack of these signals may be observed by the customer to indicate to him that the package was opened beforehand. However, here again, unless the customer is focusing his attention on the reception of the expected signals, he is apt to miss them.
  • the combination container and tamper-proof closure construction in accordance with the present invention provides better signals, both visible and audible, at the time of purchase and at the time of opening than is achieved by the aforementioned prior art designs.
  • a good audible signal is provided at the time the package is opened in that the separable ring is permitted to drop free of the finish and free-fall downwardly until it strikes either an enlarged neck or shoulder portion of the container with sufiicient impact to make a clearly heard noise.
  • the neck of the container immediately beneath the finish is made substantially smaller than the inside diameter of the separable ring so that when a priorly opened container is removed from the retailers shelf for purchase or for inspection, the ring is clearly visible since it has dropped a considerable distance away from the top portion of the cap. It will also move about freely on the reduced diameter container neck which attracts the eye and Which also results in audible rattling sounds being made by the ring.
  • Non-tamper-proof caps of modern design having a isimlpioth sidewall or skirt are now widely accepted in the In accordance with the tamper-proof constructions of the prior art, the detents on the separable ring which prevent the ring from rotating during removal of the cap are in the form of embossments pressed into the side of the skirt of the cap.
  • a further feature of the present invention not found in prior art designs is that the cooperating detents on the separable ring of the cap on the container finish which prevent turning of the ring, also assist in keeping the cap tightly on the finish. This is of particular importance when the cap is of the prest-on turn-off type, such as disclosed in US. Patent 3,270,904, issued Sept. 6, 1966, to Charles N. Foster et al.
  • the detents also cooperate when the cap is turned for removal to create a downward reaction force on the separable ring to propel the ring downwardly at high velocity against the ring intercepting portion of the container which results in a good audible signal.
  • a package in accordance with the present invention includes a plurality of circumferentially spaced apart detents around the container finish.
  • the detents are generally disposed at an angle with respect to the container axis. These detents cooperate with a plurality of detents on the tamper-proof ring to provide resultant generally vertical reaction forces tending to hold the closure cap tightly seated on the container finish.
  • the neck portion of the container is made so that it is of substantially smaller diameter than the inside diameter of the separable ring. Due to the angled position of the detents on the container finish, and the small diameter container neck, the ring immediately terminates contact with the container and falls freely through the air until it strikes an intercepting container portion considerably below the container finish with substantial impact, to audibly report the breaking of the container seal.
  • the tamper-proof ring is clearly visibly separated and will rattle about on the container neck when the container is handled so as to audibly report the breaking of the seal to a prospective purchaser.
  • the broad object of the invention is to provide a package substantially as immediately above described.
  • FIGURE 1 is a sectional elevation view of a closure cap constructed in accordance with the principles of the invention as it appears prior to its application to a container finish;
  • FIGURE 2 is a fragmentary portion of a container having a finish adapted to accommodate the cap of FIGURE 1;
  • FIGURE 3 is a fragmentary enlarged cross-sectional view of the finish of FIGURE 2 with the cap of FIGURE 1 being applied by a capping head, shown fragmentarily, before the curl at the bottom of the skirt of the cap is pressed into engagement with a circumferential head on the finish;
  • FIGURE 4 is a view similar to FIGURE 3 with the cap in the fully seated position with the curl being in engagement with a circumferential bead on the finish;
  • FIGURE 5 is a fragmentary perspective view of a container and cap construction as shown in FIGURES 1-4, illustrating the position of the separable ring rest ing on the shoulder portion of the container after the container has been opened;
  • FIGURE 6 is a view similar to FIGURE 4, showing a slightly modified cap construction in which the lower end of the cap skirt is not provided with a curl but is turned under the circumferential head;
  • FIGURE 7 is an elevational view, partly broken away. of a modified form of cap shell prior to the application to a container finish;
  • FIGURE 8 is a fragmentary elevational view of a con tainer having a finish adapted to receive the cap shell of FIGURE 7 thereon;
  • FIGURE 9 is a fragmentary enlarged cross-sectional view of the container finish of FIGURE 8 with the cap shell of FIGURE 7 being applied thereover and just prior to the formation of embossed thread formations in the side-wall of the cap skirt;
  • FIGURE 10 is a view similar to FIGURE 9, with the thread formations in the side-wall of the cap skirt having been completed so that the cap is firmly engaged with the container finish and with the curl at the lower end of the cap skirt being in engagement with detents on the container finish; and,
  • FIGURE 11 is a view similar to FIGURE 10, but showing the separable ring of the cap dropping away from the upper cap portion in a free-fall and just before making audible contact with an enlarged shoulder portion of the container.
  • the closure cap 10 includes a top panel portion 11 having a shoulder portion 12 forming one margin of a gasket groove 13 while the outer margin is defined by the depending skirt portion 14.
  • the inner circumferential surface 15 of the skirt 14, as well as the gasket groove 13 at the juncture of the skirt and top panel portion, is filled with a layer of flowable plasticlike gasket material 16 for sealing to a container finish and formation of means to facilitate rotational removal of the closure cap.
  • the gasket material may be of the type described in US. Patents 2,874,863, issued to Harold W. Unger et al., on Feb. 24, 1959 and 2,841,304. issued to Donald H. Zipper on July 1, 1968, or the equivalent.
  • skirt 14 is in the form of a separable tamper-proof ring 118 which is connected to the upper skirt portion through a series of frangible bridging portions 19 at spaced intervals.
  • the lower margin of the tamper-proof ring 18 may he curled as at 20.
  • a fragmentary portion of a container is illustrated at 22 in FIGURE 2, having a necked-in portion 23 defining a neck of the container located directly below the container sealing finish portion 24.
  • the sealing finish portion 24 is provided with a plurality of inclined multistart threads or camming surfaces 25 which may be constructed in accordance with the teachings of the US. patent to C. N. Foster et al., No. 3,270,904, issued Sept. 6, 1966.
  • the lower end of the sealing finish portion is in the form of a circumferential head 26 having circumferentially spaced apart detents 27 in the form of hollows in the rounded undersurface of the bead 26.
  • FIGURE 3 is illustrated an enlarged half-sectional view of the closure cap of FIGURE 1 being applied to the container finish of FIGURE 2.
  • Capping head 32 presses the closure cap 10 onto the rim 28 of the container finish causing the gasket compound 16 to flow around the multi-start threads 25 creating inclined hollow thread formations or camming surfaces 29 in the gasket compound 16.
  • the details of this feature are fully described in the above-mentioned Foster et al. patent.
  • punch 33 engages the curl 20 to force it radially inward into contact with the circumferential head 26 as shown in FIGURE 4.
  • Punch 33 maybe continuous or can engage the curl at spaced points around the closure cap depending upon the particular application. In either event, the deformation of the curl 20 radially inward to the position as shown in FIG- URE 4 serves to assist in maintaining the closure cap 10 on the container finish 24.
  • the curl 28 When the curl 28 comes into contact with the circumferential bead 26, it deforms so that portions of the curl 20 fit into the detents 27 with the remaining portions contacting the rounded under-surface of the bead 26 be tween the detents 27.
  • the portions of the curl 20 that fit into the detents are in the form of matching detents 34 in the separable tamper-proof ring 18 as seen in FIG- URE 5.
  • the separable tamper-proof ring 18 has come to rest on an enlarged shoulder portion 35 of the container 22.
  • the separable ring 18 falls freely through the air a considerable verti cal distance before it audibly strikes the enlarged shoulder portion 35 so that it is easily observed by a prospective customer to be separated from the cap.
  • the necked-in portion of the container 23 is considerably smaller than the inside diameter of the ring 18 so that when the container 22 is picked up by a prospective customer and moved about, the separated ring 18 will rattle on the container neck 23 to further indicate that the container was priorly opened.
  • the detents 27 are provided in the undersurface of the circumferential head 26 and are generally disposed at an angle L from the vertical axis of the container.
  • the resultant reaction force F exerted by the surface of a detent 27 of the container against the surface of a detent 34 on the separable ring 18 is generally vertical. Since the reaction force F is nearly vertical, it will have a large vertical component tending to hold the closure cap securely in place on the container 22 so as to maintain the rim 28 securely sealed in the gasket material 16.
  • the gasket material 16 is in a relatively soft or pliable condition and may not be effective to adequately hold the cap in place without the holding action of the curl against the circumferential head 26 and the hollow detents 27 therein.
  • the relationship of the cooperating detents 27 on the sealing finish and the detents 34 on the separable ring 118 permit the depending skirt portion of the cap 14 to be free of the usual protuberances found in the prior art tamper-proof constructions.
  • the smooth skirt 14 lends modern styling to the closure cap 10 which provides a competitive edge in sales appeal.
  • the main purpose of the detents 27 cooperating with the detents 34 on the separable ring 18 is to prevent the ring 18 from rotating when the closure cap 10 is being turned for removal.
  • shearing stresses are set up in the frangible bridging portions 19 which connect the separable ring portion of the cap 14) from the upper portion of the cap indicated at 36.
  • the shearing stresses in the bridging portions 19 result in the fracture of the bridging portions and the separation of the ring 18 from the upper cap portion 36.
  • the resultant reaction force F of the hollow surface of the detents 27 against the detents 34 will be of increased magnitude and will tilt in a clockwise direction so as to be about as illustrated in FIGURE 2 during removal of the upper cap portion.
  • the force F has a horizontal component Fx and a vertical component Fy which are approximately equal in magnitude.
  • the horizontal component Fx is responsible for preventing the rotation of the separable ring 18 on the sealing finish during the removal of the upper cap portion 36.
  • the vertical component Fy causes the separable ring 18 to be propelled downwardly with considerable force at the instant the frangible bridging portions snap, resulting in the ring 18 striking the shoulder portion with sufficient force to provide an audible report that the sealed container was not priorly opened.
  • FIGURE 6 is depicted a modified version of the cap 10 which is indicated generally at 10 applied to the container 22.
  • the cap 10 is similar in all respects to the cap 10 with the exception of the elimination of the curl 20 on the separable ring 18, and prime numerals have therefore been employed to indicate the portions of the cap 10' that have the same designation as respective similar numerals used in the description of the cap 10.
  • the skirt portion adjacent the marginal edge indicated at 37 at the bottom of the depending slL rt portion 14 is merely turned inwardly under the circumferential bead 26 and pressed into the hollow detents 27 so as to form the detents 34' on the separable ring 18 which prevent the separable ring 18 from rotating upon turning of the upper cap portion 36' during removal thereof.
  • the detents 34 are contiguous with the marginal edge 37.
  • cap 10' has most of the important features provided by the cap 10.
  • the depending skirt portion 14' is smooth and free of normally visible protuberances in keeping with the modern design concepts.
  • the detents 27 and 34 are completely hidden from View with only the smoothly rounded curl 20 being visible to the customer, the detents 34' are substantially hidden from view as the cap 10 on a container 22 would normally be viewed on a retailers shelf.
  • the marginal edge 34 although not completely hidden from view from all angles of observation, is substantially hidden from view as the cap 10" is normally viewed on the retailers shelf.
  • FIGURE 7 is depicted a modified form of closure shell made in accordance with the invention and indicated at 38.
  • the closure shell 38 is adapted to be applied to the sealing finish 40 of a container 41 partially depicted in FIGURE 8.
  • the closure shell 38 has a top panel portion 42 and a depending skirt portion 43 at the marginal edge of the top panel.
  • a separable tamper-proof ring 44 is provided around the circumference of the lower end of the depending skirt portion and is connected by means of a plurality of frangible bridging portions 45 to the upper cap portion 46.
  • a circumferential curl indicated at 47 At the lower extremity of the tamperproof ring 44 is provided a circumferential curl indicated at 47.
  • a suitable gasket 48 is provided in contiguous relationship with the interior of the top panel portion 42 for seating on the upper rim 51 of the sealing finish 40 of the container 41.
  • Container 41 is provided with a continuous inclined thread formation 52 on the sealing finish 40.
  • the lower end of the finish 40 comprises a circumferential bead 53 having disposed on an undersurface thereof a plurality of detents in the form of raised protuberances or beads indicated at 54.
  • Protuberances or beads 54 blend into the container neck 55.
  • Container neck 55 is of reduced diameter and extends downwardly at reduced diameter until it blends into an increased diameter shoulder portion 56.
  • closure shell 38 illustrated in FIGURE 7 does not have thread formations in the depending skirt portion 43 before it is applied to the container 41.
  • the shell 38 is merely placed over the sealing finish 40 in the initial stage of application.
  • the depending skirt portion 43 is rolled about the periphery thereof so as to form an embossed thread formation 57 therein over the thread formation 52 on the container finish as seen in FIGURE 10.
  • the detents or beads 54 are disposed along the undersurface of the bead 53 and at an angle L from the vertical axis of the container.
  • the reactional forces F one of which is shown in FIGURE 10 of the beads against the detents 58, will have a vertical component of a large magnitude since the forces F will be substantially vertically disposed. The force F thus aids in holding the closure 38 tightly seated on the container finish.
  • the counter-clockwise turning of the closure during removal causes the reaction of force F of the individual bead 54 against the individual detent 58 to increase in magnitude and to be tilted in a clockwise direction so as to have a horizontal component Fx as well as a vertical component Fy.
  • the horizontal component Fx resists the tendency of the tamper-proof ring 44 to turn which results in shearing forces being set up in the frangible bridging portions 45, causing the bridging portions 45 to snap, releasing the tamper-proof ring 44.
  • the vertical component of the reaction force F namely, Fy, exerts a downward force on the ring 44 which causes the ring 44 to be rapidly propelled downwardly immediately upon the snapping of the bridging portions 45.
  • the separable ring 44 immediately drops free of the container finish 40 and free-falls a considerable distance through the air before striking the enlarged shoulder portion 56. Due to the ring being propelled downwardly at relatively high velocity as a result of the vertical force F'y, the ring will strike the shoulder 56 with considerable impact resulting in an easily heard signal being produced to indicate to the person opening the container that it was not previously opened.
  • the separable ring 44 will be positioned on the shoulder portion 56 of the container a considerable distance below the upper cap portion 46 where it is readily observed as being separated by prospective purchasers. Furthermore, the neck 55 being of reduced diameter as compared to the inside diameter of the tamper-proof ring 44, will permit rattling and freeswinging of the ring on the neck 55 when a prospective purchaser handles the container 41 so as to additionally audibly and visually indicate that the container was priorly opened.
  • bead-type detents 54 may be substituted for the hollowed-out type detents 27 and used in cooperation with the closure caps 10 and 10' of FIGURES 1-6.
  • the hollowed-out detents 27 may be used in lieu of the bead type detents 54 in the embodiment of the invention illustrated in FIGURES 7-11.
  • a tamper-proof package comprising:
  • a closure cap adapted to be received over said sealing finish
