United States Patent 3,104,039 PLASTEC CAPTJWE SEAL CLOSURE AND SPGUT Roy W. Dike, Wheeling, W. 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.

and shows the specific relationship of the closure with respect to the container, and the specific details and relationship of the two closure members.

FIGURE 12 is an enlarged fragmentary vertical sectional view similar to FIGURE 11, and shows the upper closure member rotated to a sealed position with respect to the lower closure member.

With reference to the drawings, a first embodiment of the invention is illustrated in FIGURES 1 through 4, inclusive. The closure of this embodiment of the invention is generally referred to by thenumeral 15 and is mounted on a container, generally referred to by thenumeral 16. Thecontainer 16 includes abody 17 which may be of any configuration, thebody 17 terminating at its upper end in aneck finish 18 which hasexternal threads 19.

Theclosure 15 is of a two-part construction, and is preferably formed of plastic, although other materials may sufiice. member, generally referred to by thenumeral 20, and an upper closure member, generally referred to by thenumeral 21. Theclosure 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 askirt 23. Theskirt 23 hasinternal threads 24 which are interlocked with thethreads 19 of the neck finish 18 :so as to secure thelower closure member 29 to thecontainer 16. s

Theupper portion 22 of thelower closure member 20 has anannular recess 25 formed in the underside thereof,

Theclosure 15 includes a lower closure J the recess extending around a downwardly disposedprojection 26 which is centrally located. Theprojection 26 has an upwardly openingcounterbored socket 27 formed in the upper part thereof.

The upper and outer peripheral part of theupper portion 22 is configurated to define an upwardly projectingshoulder 28 which forms the lower boundary of apcripheral recess 29. The upper boundary of therecess 29 is defined by anannular flange 3%} which projects slightly upwardly of the upper surface of the remainder of theupper portion 22, and which terminates inwardly of the periphery of theskirt 23 to leave a portion of theshoulder 28 exposed.

Theupper closure member 21 includes a lower, relatively fiat, disk-like portion 31 which overlies theupper portion 22. Theupper closure member 21 also includes a dispensingspout 32 which is formed integrally with thelower portion 3 1.

Thelower portion 31 has a depending, centrally located, headedpin 33 which is seated within thesocket 27 to interlock the upper and lower closure members. Thelower portion 31 of theupper closure member 21 also includes a narrow dependingskirt 34 which terminates in an inwardly directedlocking rib 35 which is seated on theshoulder 28 and in therecess 29 to further interlock thelower closure member 20 and theupper closure 21. While the upper and lower closure members are interlocked together, theupper closure member 21 is rotatable relative to thelower closure member 20.

It is to be noted that the underside of thelower portion 22 seats on the upper end of theneck finish 18, as at 36, to form a seal therewith. However, the contents of thecontainer 16 may be dispensed therefrom through abore 37 formed in thelower portion 22, thebore 37 being eccentrically located.

The dispensingspout 32 of theupper closure member 21 has abore 38 therethrough, thebore 38 increasing in diameter towards the bottom thereof and opening through thelower portion 31. Thebore 38 is also eccentrically positioned and may be rotated into alignment with thebore 37 so that the contents of thecontainer 16 may be poured through thealigned bores 37 and 38, and thus dispensed.

Theupper portion 22 of theclosure member 20 has anannular locking ring 39 which encircles thebore 37. The underside of thelower portion 31 of theupper closure member 21 is provided with anannular recess 40 in which thelocking ring 39 is disposed when thebores 37 and 38 are aligned to lock theupper closure member 21 in a dispensing position with respect to thelower closure member 20.

Theupper closure member 21 also has acircular recess 42 formed in the underside thereof. Therecess 42 is eccentrically positioned with respect to the center of thepin 33 and is preferably in diameterically opposite relation with respect to thebore 38. Therecess 42, is of a size to receive thelocking ring 39, as is best shown in FIGURE 4, to lock theupper closure 21 against rotation in a sealed position with respect to thelower closure member 20.

Reference is now made to FIGURE 2 in particular, wherein it will be seen that theupper portion 22 of thelower closure member 20 has a vent opening 4 3 formed therethrough. Asimilar vent opening 44 extends through thelower portion 31 of theupper closure member 21. When thebores 37 and 38 are aligned, thevent openings 43 and 44 are also aligned to permit the entrance of air into thecontainer 16 through theclosure 15 during the dispensing of the contents of the container.

It is to be understood that thelower closure member 20 and theupper 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, theclosure 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 theclosure 15 is formed, the lockingring 39 may snap into and out of therecesses 40 and 42 and the desired seal may be maintained between the twoclosure 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 theclosure 51 may be of any design, it

is illustrated as having acylindrical body portion 52 and a reduceddiameter neck finish 53 which terminates at its upper end in an outwardly projecting lockingrib 54. The lockingrib 54 is generally of a frusto-conical configuration, as is best illustrated in FIGURES 7 and 8. Theneck finish 53 also includes a smoothcylindrical mouth 55.

The closure 50 is of a two-piece constluction, and includes alower 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.

Thelower 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 theneck finish 53. Thelower closure member 56 also includes a dependingskirt 59 which is integrally formed with theupper portion 58 and which depends therefrom inwardly of the periphery thereof. Theskirt 59 is relatively deep and is of a diameter to be snugly received within the mouth of theneck finish 53. Theskirt 59 serves to both center thelower closure member 56 and to form a seal with themouth 55. It is to be noted that theskirt 59 is tapered so as to have a minimum cross section at the lower end thereof. This tapered construction facilitates the entry of theskirt 59 into themouth 55 and is best shown in FIGURES 7 and 8.

Theupper closure member 57 includes a lowerdisklike 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 dispensingspout 61 projects upwardly from thelower portion 60 and is formed integrally therewith. A depending, downwardly and outwardly flaringskirt 62 is formed integrally with thelower portion 60 at the pcriphery thereof. Theskirt 62 terminates in an inwardly directed locking rib orflange 63. The flare of theskirt 62 corresponds generally to the slope of the lockingrib 54 and the lockingrib 63 underlies the lockingrib 54 to lock the closure 50 on thecontainer 51.

The central part of theupper portion 58 of thelower closure member 56 includes a dependingprojection 64. An undercutsocket 65 is formed in theupper portion 58 and opens through the upper surface thereof in alignment with theprojection 64. Thelower portion 60 of theupper closure member 57 has a downwardly projecting headedpin 66 which is seated within thesocket 65 to interlock thelower closure member 56 and theupper closure member 57. The central part of thelower portion 60 is in pressure contact with the central part of theupper portion 58 when theupper closure member 57 is snapped onto theneck finish 53 of thecontainer 51. This pressure urges thelower closure member 56 downwardly and the underside of theupper portion 58 outwardly of theskirt 59 is in pressure contact with the upper edge oftheneck finish 53, as at 67, to form an effective seal between thelower closure member 56 and thecontainer 51.

Theupper 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 theupper portion 58 is provided with aboss 69 through which thebore 68 opens. Theboss 69 has a generally horizontally disposed upper surface, as compared to the sloping upper surface of theupper portion 58. The upper surface of theboss 69 is configurated to define an upwardly projectinglocking ring 70 surrounding thebore 68 and anannular groove 71 surrounding thellocking ring 70.

A generallycylindrical recess 72 is formed in the underside of theupper portion 60 in an eccentric position. Therecess 72 is generally defined by a downwardly projectingannular ring 73. The relationship of thebore 68 and therecess 72 is such that when theclosure members 56 and 57 are properly aligned, thebore 68 is aligned with therecess 72. At this time, the lockingring 70 projects into therecess 72. At the same time, theannular ring 73 of theupper closure member 57 is seated in the annular groove orrecess 71. In this manner, the upper closure member '57 is interlocked in sealed relation with respect to thelower closure member 56. This is best illustrated in FIGURE 8.

The dispensing spout 6 1 has abore 74 extending therethrough and opening through the underside of thelower portion 60 of theupper closure member 57. Thebore 74 is surrounded by arib 75 which is spaced outwardly of thebore 74 to define anenlarged extension 76 of thebore 74.

Due to the eccentric positions of both thebore 74 and thebore 68, when theclosure member 57 is properly rotated with respect to theclosure member 56, thebores 68 and 74 are aligned, as is best illustrated in FIGURE 7. When theclosure members 56 and 57 are in this position, the lockingring 70 is seated in thebore extension 76, and the ring orrib 75 is seated in thegroove 71. Thus, theclosure members 56 and 57 are in interlocked sealed relation, although the contents of thecontainer 51 maybe dispensed through the aligned bores "68 and 74.

Theupper closure member 57 has a vent opening 77 which opens through thelower portion 60 thereof. Asimilar vent opening 78 is formed in the lower closure member '56, thevent opening 78 extending through theupper portion 58. When thebores 68 and 74 are aligned, thevent 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 thevent 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 theclosure members 56 and 57 are formed of a flexible, resilient plastic material, the headedpin 66 may be readily interlocked in thesocket 65 to interlock theclosure members 56 and 57 together. Further, the lockingrib 63 may be readily snapped beneath the lockingrib 54 of theneck finish 53. In addition, the flexibility and resiliency of the plastic material permits the desired seal between the closure 50 and thecontainer 51, and theclosure 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.

Thecontainer 86 may be of any configuration, but is illustrated 'as being in the form of a container having acylindrical body 87 of a relatively small diameter. Thebody 87 terminates at the upper end thereof in a neck finish, generally referred to by the numeral 88. Theneck finish 88 includes an outwardly projecting lowerannular rib 89, the upper surface of which defines ashoulder 90. Theneck finish 88 also includes an inwardly offsetmouth portion 91 which terminates at its upper end in an outwardly projecting lockingrib 92, the underside of the lockingrib 92 being spaced above theshoulder 90.

Theclosure 85 is of a two-piece construction and in cludes alower closure member 93 and anupper closure member 94. Theclosure members 93 and 94 are disposed in interlocked telescoped relation, when assembled, as is best illustrated in FIGURES l1 and 12.

Thelower closure member 93 includes anupper portion 95 in the form of a relatively flat, circular disk. Theupper portion 95 has an integral, dependingskirt 96 which terminates at its lower end in an inwardly directed lockingrib 97 which is engaged under the lockingrib 92 to retain thelower closure member 93 on thecontainer 86. Thelower closure member 93 also includes aninner skirt 98 which is relatively shallow and which depends from the underside of theupper portion 95. Theinner skirt 98 engages the inner surface of themouth 91 and serves to both form a seal therewith and to center thelower closure member 93. Theskirt portion 96 istensioned when thelower closure member 93 is positioned on theneck finish 88, and a seal is formed between the underside of theupper portion 95 and the upper end of theneck finish 88, as at 99.

Theupper closure member 94 includes an upwardly projecting dispensing spout 160 which is formed integral with the projects upwardly from alower portion 101. The lower portion 161 in the form of :a relatively flat disk. A dependingskirt 102 is formed integrally with the peripheral surface of thelower portion 101. Theskirt 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 thecontainer 86, theskirt 102 is telescoped over thelower closure member 93, and the lockingflange 103 thereof is locked beneath the lockingrib 97 of thelower closure member 93. When theclosure 85 is assembled on thecontainer 86, it is preferred that theskirt 102 be slightly under tension so that thelower portion 101 will be in a slight compressive face-t-o-face engagement with the upper portion to provide the desired seal between thelower closure member 93 and theupper closure member 94.

Theupperportion 95 of thelower 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 thelower portion 101 of theupper closure member 94 is provided with an eccentrioally positioned cylindrical recess 166 which may be aligned with thebore 104, and when so aligned, receives thelocking ring 105 to provide both a seal between theclosure members 93 and 94 and an interlock between the two to resist relative rotation between theclosure 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 thebore 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 enlargedlower portion 108 to provide the desired seal between theclosure members 93 and 94 and to restrain the two against relative rotation. When thebores 104 and 187 are aligned, as illustrated in FIGURE 11, the contents of thecontainer 86 may be readily dispensed therefrom. On the other hand, when thebore 104 is aligned with the recess 196, thecontainer 86 is sealed by theclosure 85.

As is best illustrated in FIGURE 10, thelower closure member 93 has an eccentrically positionedvent opening 109. Theupper 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 thecontainer 86, thevent openings 169 and 110 are also aligned so as to vent the interior of thecontainer 86 during the dispensing of the contents thereof.

Theclosure 85 is preferably formed of a flexible and resilient plastic material, such as polyethylene. By so forming thelower closure members 93 and 94 of such material, thelower closure member 93 and theupper closure member 94 may be readily snapped over theneck finish 88 with portions thereof remaining in tension to provide the necessary seal between thelower closure member 93 and thecontainer 86, and the desired seal between theclosure members 93 and 94 to permit the sealing of thecontainer 86 by theclosure 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.
