Va, assignor to Continental Can Company, Inc, New York, N.!., a corporation of New York Filed Apr. 12, 1960, Ser. No. 21,738 Claims. (El. ZZZ-536) This invention relates in general to new and useful improvements in closures for containers, and more particularly relates to a captive closure of the dispensing type which may be permanently secured to a container and which may be selectively opened and closed for the dispensing of the contents of the container and the sealing thereof.
A primary object of the invention is to provide a novel closure for containers, such as bottles and the like, the closure being of a two-piece construction and including a lower member which is sealed with respect to the container and which has a small dispensing opening therethrough, and an upper member which overlies the lower member and which has a dispensing spout, the upper member being rotatable relative to the lower member to selectively align the dispensing spout with the opening in the lower member to facilitate the dispensing of the contents of the container to which the closure is attached.
Another object of the invention is to provide a twopiece closure for a container, the closure being of the captive type intended to be permanently mounted on the container and including a lower member which is sealed with respect to the container and an upper member which is rotatable on the lower member, the lower member and the upper member having interlocking parts for selectively locking the upper member in a container sealing position with respect to the lower member and a dispensing position whereby the contents of the container may be readily dispensed.
Still another object of the invention is to provide a novel captive closure of the dispensing type, the captive closure being of a two-piece construction and including a lower member and an upper member which are mounted in interconnected relation with the upper member overlying the lower member, the lower member having a dispensing bore therethrough with the upper part of the bore being encircled by an upwardly projecting ring, and the upper member having a dispensing spout and a recess disposed generally diametrically opposite to the dispensing spout, the upper member being rotatable relative to the lower member and selectively positioned with respect to the lower member to have the locking ring disposed either within the recess so as to retain the upper member in a sealed relation with respect to the lower member, or in alignment with the dispensing spout to align the dispensing spout with the dispensing bore of the lower member to facilitate the dispensing of the contents of the container on which the closure is mounted.
A further object of the invention is to provide a novel two-piece captive seal closure which is formed of plastic material and which may be readily assembled, the closure construction being of a nature to permit a variation of structural relationships so that the closure may be mounted on containers of varied construction.
With the above, and other objects in view that will hereinafter appear, the nature of the invention will be more clearly understood by reference to the following detailed description, the appended claims, and the several views illustrated in the accompanying drawings.

The container 16 includes a body 17 which may be of any configuration, the body 17 terminating at its upper end in a neck finish 18 which has external threads 19.
The closure 15 is of a two-part construction, and is preferably formed of plastic, although other materials may sufiice. member, generally referred to by the numeral 20, and an upper closure member, generally referred to by the numeral 21. The closure mentubers 2t and 21 are interlocked together and are rotatable relative to each other, in a manner .to be described in detail hereinafter.
The lower closure member Ztl includes an upper, fiat, disk-like portion 22 which has depending from the periphery thereof a skirt 23. The skirt 23 has internal threads 24 which are interlocked with the threads 19 of the neck finish 18 :so as to secure the lower closure member 29 to the container 16. s
The upper portion 22 of the lower closure member 20 has an annular recess 25 formed in the underside thereof,
The closure 15 includes a lower closure J the recess extending around a downwardly disposed projection 26 which is centrally located. The projection 26 has an upwardly opening counterbored socket 27 formed in the upper part thereof.
The upper and outer peripheral part of the upper portion 22 is configurated to define an upwardly projecting shoulder 28 which forms the lower boundary of a pcripheral recess 29. The upper boundary of the recess 29 is defined by an annular flange 3%} which projects slightly upwardly of the upper surface of the remainder of the upper portion 22, and which terminates inwardly of the periphery of the skirt 23 to leave a portion of the shoulder 28 exposed.
The upper closure member 21 includes a lower, relatively fiat, disk-like portion 31 which overlies the upper portion 22. The upper closure member 21 also includes a dispensing spout 32 which is formed integrally with the lower portion 3 1.
The lower portion 31 has a depending, centrally located, headed pin 33 which is seated within the socket 27 to interlock the upper and lower closure members. The lower portion 31 of the upper closure member 21 also includes a narrow depending skirt 34 which terminates in an inwardly directed locking rib 35 which is seated on the shoulder 28 and in the recess 29 to further interlock the lower closure member 20 and the upper closure 21. While the upper and lower closure members are interlocked together, the upper closure member 21 is rotatable relative to the lower closure member 20.
It is to be noted that the underside of the lower portion 22 seats on the upper end of the neck finish 18, as at 36, to form a seal therewith. However, the contents of the container 16 may be dispensed therefrom through a bore 37 formed in the lower portion 22, the bore 37 being eccentrically located.
The dispensing spout 32 of the upper closure member 21 has a bore 38 therethrough, the bore 38 increasing in diameter towards the bottom thereof and opening through the lower portion 31. The bore 38 is also eccentrically positioned and may be rotated into alignment with the bore 37 so that the contents of the container 16 may be poured through the aligned bores 37 and 38, and thus dispensed.
The upper portion 22 of the closure member 20 has an annular locking ring 39 which encircles the bore 37. The underside of the lower portion 31 of the upper closure member 21 is provided with an annular recess 40 in which the locking ring 39 is disposed when the bores 37 and 38 are aligned to lock the upper closure member 21 in a dispensing position with respect to the lower closure member 20.
The upper closure member 21 also has a circular recess 42 formed in the underside thereof. The recess 42 is eccentrically positioned with respect to the center of the pin 33 and is preferably in diameterically opposite relation with respect to the bore 38. The recess 42, is of a size to receive the locking ring 39, as is best shown in FIGURE 4, to lock the upper closure 21 against rotation in a sealed position with respect to the lower closure member 20.
Reference is now made to FIGURE 2 in particular, wherein it will be seen that the upper portion 22 of the lower closure member 20 has a vent opening 4 3 formed therethrough. A similar vent opening 44 extends through the lower portion 31 of the upper closure member 21. When the bores 37 and 38 are aligned, the vent openings 43 and 44 are also aligned to permit the entrance of air into the container 16 through the closure 15 during the dispensing of the contents of the container.
It is to be understood that the lower closure member 20 and the upper closure member 21 may be readily molded of a plastic material. Further, because of the flexibility and resiliency of the plastic material which is utilized, the plastic material being polyethylene, for example, the closure members 20 and 21 may be readily snapped together and will remain in the interlocked relation illustrated in the drawings. Furthermore, because of the resiliency of the material from which the closure 15 is formed, the locking ring 39 may snap into and out of the recesses 40 and 42 and the desired seal may be maintained between the two closure members 20 and 21.
A second embodiment of the invention is illustrated in FIGURES 5 through 8, inclusive. The closure illustrated in these figures is generally referred to by the numeral and is mounted on a container, generally referred to by the numeral 51.
Although the closure 51 may be of any design, it
is illustrated as having a cylindrical body portion 52 and a reduced diameter neck finish 53 which terminates at its upper end in an outwardly projecting locking rib 54. The locking rib 54 is generally of a frusto-conical configuration, as is best illustrated in FIGURES 7 and 8. The neck finish 53 also includes a smooth cylindrical mouth 55.
The closure 50 is of a two-piece constluction, and includes a lower closure member 56 and an upper clo sure member 5'7. The closure members are interlocked in a manner to be described in detail hereinafter, and will be supplied as a unit.
The lower closure member 56 includes an upper, slightly domed disk-like portion 58 which is of a diameter substantially equal to the diameter of the upper end of the neck finish 53. The lower closure member 56 also includes a depending skirt 59 which is integrally formed with the upper portion 58 and which depends therefrom inwardly of the periphery thereof. The skirt 59 is relatively deep and is of a diameter to be snugly received within the mouth of the neck finish 53. The skirt 59 serves to both center the lower closure member 56 and to form a seal with the mouth 55. It is to be noted that the skirt 59 is tapered so as to have a minimum cross section at the lower end thereof. This tapered construction facilitates the entry of the skirt 59 into the mouth 55 and is best shown in FIGURES 7 and 8.
The upper closure member 57 includes a lower disklike portion 60 which has the underside thereof relatively flat, but which is of an increased thickness in the center thereof so that the upper surface thereof is slightly domed. A dispensing spout 61 projects upwardly from the lower portion 60 and is formed integrally therewith. A depending, downwardly and outwardly flaring skirt 62 is formed integrally with the lower portion 60 at the pcriphery thereof. The skirt 62 terminates in an inwardly directed locking rib or flange 63. The flare of the skirt 62 corresponds generally to the slope of the locking rib 54 and the locking rib 63 underlies the locking rib 54 to lock the closure 50 on the container 51.
The central part of the upper portion 58 of the lower closure member 56 includes a depending projection 64. An undercut socket 65 is formed in the upper portion 58 and opens through the upper surface thereof in alignment with the projection 64. The lower portion 60 of the upper closure member 57 has a downwardly projecting headed pin 66 which is seated within the socket 65 to interlock the lower closure member 56 and the upper closure member 57. The central part of the lower portion 60 is in pressure contact with the central part of the upper portion 58 when the upper closure member 57 is snapped onto the neck finish 53 of the container 51. This pressure urges the lower closure member 56 downwardly and the underside of the upper portion 58 outwardly of the skirt 59 is in pressure contact with the upper edge of theneck finish 53, as at 67, to form an effective seal between the lower closure member 56 and the container 51.
The upper portion 58 of the lower closure member has an eccentrically located dispensing bore 68 opening therethrough. As is best illustrated in FIGURE 6, the upper surface of the upper portion 58 is provided with a boss 69 through which the bore 68 opens. The boss 69 has a generally horizontally disposed upper surface, as compared to the sloping upper surface of the upper portion 58. The upper surface of the boss 69 is configurated to define an upwardly projecting locking ring 70 surrounding the bore 68 and an annular groove 71 surrounding the llocking ring 70.
A generally cylindrical recess 72 is formed in the underside of the upper portion 60 in an eccentric position. The recess 72 is generally defined by a downwardly projecting annular ring 73. The relationship of the bore 68 and the recess 72 is such that when the closure members 56 and 57 are properly aligned, the bore 68 is aligned with the recess 72. At this time, the locking ring 70 projects into the recess 72. At the same time, the annular ring 73 of the upper closure member 57 is seated in the annular groove or recess 71. In this manner, the upper closure member '57 is interlocked in sealed relation with respect to the lower closure member 56. This is best illustrated in FIGURE 8.
The dispensing spout 6 1 has a bore 74 extending therethrough and opening through the underside of the lower portion 60 of the upper closure member 57. The bore 74 is surrounded by a rib 75 which is spaced outwardly of the bore 74 to define an enlarged extension 76 of the bore 74.
Due to the eccentric positions of both the bore 74 and the bore 68, when the closure member 57 is properly rotated with respect to the closure member 56, the bores 68 and 74 are aligned, as is best illustrated in FIGURE 7. When the closure members 56 and 57 are in this position, the locking ring 70 is seated in the bore extension 76, and the ring or rib 75 is seated in the groove 71. Thus, the closure members 56 and 57 are in interlocked sealed relation, although the contents of the container 51 maybe dispensed through the aligned bores "68 and 74.
The upper closure member 57 has a vent opening 77 which opens through the lower portion 60 thereof. A similar vent opening 78 is formed in the lower closure member '56, the vent opening 78 extending through the upper portion 58. When the bores 68 and 74 are aligned, the vent openings 77 and 78 are also aligned to permit the venting of the container '51 while the contents thereof are being dispensed. The relative positions of the vent openings 77 and 78 are best illustrated in FIGURE 6.
The closure 50 is preferably formed of a resilient plastic material, such as polyethylene. When the closure members 56 and 57 are formed of a flexible, resilient plastic material, the headed pin 66 may be readily interlocked in the socket 65 to interlock the closure members 56 and 57 together. Further, the locking rib 63 may be readily snapped beneath the locking rib 54 of the neck finish 53. In addition, the flexibility and resiliency of the plastic material permits the desired seal between the closure 50 and the container 51, and the closure members 56 and 57 of the closure 50.
Another embodiment of the invention is illustrated in FIGURES 9 through 12, inclusive. The closure illustrrated in these figures is generally referred to by the numeral 85 and is mounted on a container, which is generally referred to by the numeral 86.
The container 86 may be of any configuration, but is illustrated 'as being in the form of a container having a cylindrical body 87 of a relatively small diameter. The body 87 terminates at the upper end thereof in a neck finish, generally referred to by the numeral 88. The neck finish 88 includes an outwardly projecting lower annular rib 89, the upper surface of which defines a shoulder 90. The neck finish 88 also includes an inwardly offset mouth portion 91 which terminates at its upper end in an outwardly projecting locking rib 92, the underside of the locking rib 92 being spaced above the shoulder 90.
The closure 85 is of a two-piece construction and in cludes a lower closure member 93 and an upper closure member 94. The closure members 93 and 94 are disposed in interlocked telescoped relation, when assembled, as is best illustrated in FIGURES l1 and 12.
The lower closure member 93 includes an upper portion 95 in the form of a relatively flat, circular disk. The upper portion 95 has an integral, depending skirt 96 which terminates at its lower end in an inwardly directed locking rib 97 which is engaged under the locking rib 92 to retain the lower closure member 93 on the container 86. The lower closure member 93 also includes an inner skirt 98 which is relatively shallow and which depends from the underside of the upper portion 95. The inner skirt 98 engages the inner surface of the mouth 91 and serves to both form a seal therewith and to center the lower closure member 93. The skirt portion 96 istensioned when the lower closure member 93 is positioned on the neck finish 88, and a seal is formed between the underside of the upper portion 95 and the upper end of the neck finish 88, as at 99.
The upper closure member 94 includes an upwardly projecting dispensing spout 160 which is formed integral with the projects upwardly from a lower portion 101. The lower portion 161 in the form of :a relatively flat disk. A depending skirt 102 is formed integrally with the peripheral surface of the lower portion 101. The skirt 102, terminates at the lower end thereof in a locking flange 1%. It is to be noted that when the closure is assembled and positioned on the container 86, the skirt 102 is telescoped over the lower closure member 93, and the locking flange 103 thereof is locked beneath the locking rib 97 of the lower closure member 93. When the closure 85 is assembled on the container 86, it is preferred that the skirt 102 be slightly under tension so that the lower portion 101 will be in a slight compressive face-t-o-face engagement with the upper portion to provide the desired seal between the lower closure member 93 and the upper closure member 94.
The upperportion 95 of the lower closure member 93 is provided with an upwardly tapered dispensing bore 104 which opens therethrough and which has the upper part thereof defined by an upwardly projecting locking ing 10-5. The underside of the lower portion 101 of the upper closure member 94 is provided with an eccentrioally positioned cylindrical recess 166 which may be aligned with the bore 104, and when so aligned, receives the locking ring 105 to provide both a seal between the closure members 93 and 94 and an interlock between the two to resist relative rotation between the closure members 93 and 94.
The dispensing sp out 189 has a bore 167 which opens downwardly through the upper portion 161. The lower part of the bore 107 includes an enlarged portion itt8.-
When the bore 167, which is eccentrically positioned, is rotated into alignment with the bore 164; the locking ring 165 snaps into the enlarged lower portion 108 to provide the desired seal between the closure members 93 and 94 and to restrain the two against relative rotation. When the bores 104 and 187 are aligned, as illustrated in FIGURE 11, the contents of the container 86 may be readily dispensed therefrom. On the other hand, when the bore 104 is aligned with the recess 196, the container 86 is sealed by the closure 85.
As is best illustrated in FIGURE 10, the lower closure member 93 has an eccentrically positioned vent opening 109. The upper closure member 94 has a similarly positioned vent opening When the bores 167 and 18-; are aligned for the purpose of dispensing the contents of the container 86, the vent openings 169 and 110 are also aligned so as to vent the interior of the container 86 during the dispensing of the contents thereof.
The closure 85 is preferably formed of a flexible and resilient plastic material, such as polyethylene. By so forming the lower closure members 93 and 94 of such material, the lower closure member 93 and the upper closure member 94 may be readily snapped over the neck finish 88 with portions thereof remaining in tension to provide the necessary seal between the lower closure member 93 and the container 86, and the desired seal between the closure members 93 and 94 to permit the sealing of the container 86 by the closure 85, if so desired.
From the foregoing, it will be seen that novel and advantageous provision has been made for carrying out the desired end. However, attention is directed to the fact that other variations may be made in the exampie embodiments disclosed herein without departing from the spirit and scope of the invention, as defined in the appended claims.
