DETAILED DESCRIPTION
[0023]
[0024] The embodiment of the sprinkler base 16 is illustrated in greater detail in
[0025] The base plate 20 is a circular disk to which the sprinkler disk 18 is secured. The base plate 20 may be configured for attachment and indexing of the sprinkler disk 18, and to create an opening for dispensing the flowable product after a consumer purchases the flowable product container 10. The base top surface 22 has an annular disk connection housing 34 located on a base central axis 36 of the sprinkler base 16 and concentric with the containment shoulder 26 (
[0026] The base plate 20 further includes an indexing detent 46 and a tongue 48 that may be disposed on diametrically opposite sides of the base central axis 36 of the base plate 20 as shown. In alternate embodiments, the indexing detent 46 and the tongue 48 may have different relative positions on the base plate 20, but will be located radially outward from the base central axis 36 on the base plate 20. The indexing detent 46 extends upward from the base top surface 22. The indexing detent 46 is positioned to radially align with corresponding indexing recesses of the sprinkler disk 18 when the sprinkler disk 18 is attached to the sprinkler base 16 to alternately open and close the flowable product container 10 when the sprinkler disk 18 is rotated relative to the sprinkler base 16 as discussed further below.
[0027] The tongue 48 is integrally formed in the base plate 20 and configured to be partially detached from the base plate 20 when a sufficient downward force is applied as described further below. The tongue 48 may have an eccentric position on the base plate 20 that is between the housing opening 38 and the containment shoulder 26 (
[0028] The base plate 20 may have a generally constant base thickness t.sub.B that is within a range from 0.50 mm to 1.00 mm?0.05 mm for a majority of the base plate 20, but may include a shear area 56 at the outward front edge 50 of the tongue 48 that has a shear thickness t.sub.Sthat is less than the base thickness t.sub.B, and may have a value that is within a range from 0.03 mm to 0.10 mm?0.01 mm. The shear area 56 may also have a shear width w.sub.S that is within a range from 0.03 mm?0.01 mm to 0.20 mm?0.05 mm. A tongue hinge 58 may be formed at a radially inward edge of the tongue 48. The tongue hinge 58 may have a hinge thickness t.sub.H that is less then the base thickness t.sub.Band greater than the shear thickness t.sub.S. In one embodiment, the hinge thickness t.sub.H may be equal to 0.30 mm?0.05 mm.
[0029] The arrangement of the tongue 48, the shear area 56 and the tongue hinge 58 facilitates partial detachment of the tongue 48 by the consumer to open the flowable product container 10 after purchase to dispense the product. When a downward force F is applied to the tongue 48 as shown in
[0030] In some embodiments, the tongue 48 may be left free to dangle below the base bottom surface 24. Alternatively, in the illustrated embodiment, the base plate 20 includes a pair of locking ribs 64 extending downward from the base bottom surface 24 on either side of the tongue 48. Referring to
[0031] The configuration of the sprinkler base 16 illustrated in
[0032] Another alternative embodiment of the sprinkler base 16 is illustrated in
[0033] The sprinkler disk 18 is illustrated in greater detail in
[0034] The disk bottom surface 74 is illustrated in greater detail in
[0035] The sprinkler disk 18 may be further configured to index the apertures 78, 80 and the cover portion 82 as the sprinkler disk 18 rotates on the sprinkler base 16. A plurality of indexing recesses 94-102 are defined in the disk bottom surface 74 and are configured to receive indexing detent 46 of the sprinkler base 16. A cover indexing recess 94 is positioned diametrically opposite the cover portion 82 and a sift indexing recess 96 is diametrically opposite the sift apertures 80. A first pour indexing recess 98 is diametrically opposite the pour aperture 78, and additional pour indexing recesses 100, 102 are circumferentially offset from the first pour indexing recess 98. The plurality of pour indexing recesses 98-102 may be provided to vary an amount of overlap between the pour aperture 78 and the product dispensing opening 62 so the size of the opening through which the flowable product can be poured can be varied to control dispensing of the flowable product.
INDUSTRIAL APPLICABILITY
[0036]
[0037] With the tongue 48 extending above the base top surface 22, rotation of the sprinkler disk 18 is substantially prevented to provide visual and tactile evidence that the flowable product container has not been subjected to tampering. After a consumer purchases the flowable product container 10, they may apply the downward force F to partially detach the tongue 48 as discussed above. After the tongue 48 is partially detached and engaged by the tongue ribs 54 as shown in
[0038] The sprinkler assembly 12 in accordance with the present disclosure provides an eco-friendly solution as a substitute for prior sprinklers fabricated from PS, which may be banned from recycling in some jurisdictions. In one embodiment, the sprinkler base 16 ifs fabricated from PP and the sprinkler disk 18 is fabricated from either PP or PE. Materials such as PP and PE do not require perforations for partial detachment of the tongue 48. The disclosed design takes advantage of the ability of such materials to be separated by shear forces. Consequently, the tongue 48 is secured to the base plate 20 without perforation openings so that the flowable product is sealed within the flowable product container 10 until the consumer partially detaches the tongue 48.
[0039] Freshness and retention of the flowable product is further ensured by the disk connection housing 34. In previous sprinkler assemblies, sprinkler bases were provided with central openings through which mounting bosses were inserted. Due to tolerances in manufacturing the sprinkler assemblies, gaps may exist between the central openings and the mounting bosses that would allow migration of vapor or oxygen into the previous containers and into the flowable product prior to purchase and opening by the consumer, and leakage of the flowable product from the container. In the design in accordance with the present disclosure, the disk connection housing 34 completely encloses the housing opening 38 to seal the container 10 prior to partially detaching the tongue 48, and to eliminate any leakage from the container 10 at the point of connection between the sprinkler base 16 and the sprinkler disk 18. After the tongue 48 is partially detached to open the container 10, flowable product can only be dispensed from the container 10 through the product dispensing opening 62 when either the pour aperture 78 or the sift apertures 80 are aligned therewith.
[0040] While the preceding text sets forth a detailed description of numerous different embodiments, it should be understood that the legal scope of protection is defined by the words of the claims set forth at the end of this patent. The detailed description is to be construed as exemplary only and does not describe every possible embodiment since describing every possible embodiment would be impractical, if not impossible. Numerous alternative embodiments could be implemented, using either current technology or technology developed after the filing date of this patent, which would still fall within the scope of the claims defining the scope of protection.
[0041] It should also be understood that, unless a term was expressly defined herein, there is no intent to limit the meaning of that term, either expressly or by implication, beyond its plain or ordinary meaning, and such term should not be interpreted to be limited in scope based on any statement made in any section of this patent (other than the language of the claims). To the extent that any term recited in the claims at the end of this patent is referred to herein in a manner consistent with a single meaning, that is done for sake of clarity only so as to not confuse the reader, and it is not intended that such claim term be limited, by implication or otherwise, to that single meaning.
