Definitions
- the neck construction of the closure is molded from plastic and may be formed integrally with the container body, such as the collapsible tube in the aforementioned U.S. patent, or the neck element may be molded as a separate component which is subsequently associated with the container body in another manner, as is well known in the art.
- the neck element includes a hollow tubular body and a central sealing plug disposed within the body and carried by circumferentially spaced radial webs, the spaces between which provide the apertures through which the contents of the container are dispensed.
- the present invention provides an improved precision-formed neck element for center lock or captive plug closures characterized by a plurality of precisely formed dispensing orifices of arcuate configuration as viewed in plan anddisposed in spaced relation to the center plug. Further, the terminal portions of the neck element bounding the dispensing orifices define a planar sheared surface of precise and controlled character so as to insure uniformity of the dispensing passages.
- FIG. I is a sectional view of the neck element of the present invention, further showing a fragmentary container body associated therewith;
- FIG. 2' is a top plan view of the neck element of the invention
- FIG. 3 is a sectional view taken along the lines 33 of FIG. 1;
- FIG. 4 illustrates a partiallyformed neck member according to the invention and prior to final fabrication thereof.
- the neck element of the present invention is shown generally at 10 and may be associated in conventional manner with a tubular container body 12 secured thereto at a joint 14 adjacent the lower shoulder of the neck element.
- the neck 10 may be formed integrally with the container body 12 if desired.
- a closure C shown in dashed lines which per se does not form a part of the present invention.
- the closure C is, however, centrally apertured at C1 for reception therethrough of the center plug 16 of the instant neck element and wherein also the closure may conventionally have threads C2 or other interengaging means for cooperation with means such as threads 18 provided on the instant neck member.
- Retaining means are provided whereby the closure C is not normally removed from the neck element during dispensing, all as shown more fully in the aforesaid patent to Grimsley et al. US Pat. No. 3,263,851.
- the neck element 10 includes the central plug 16 which is suspended as by a plurality of integrally formed radial webs 20, shown as four in number, within the tubular body portion 22 of neck 10.
- the plug 16 is imperforate and usually molded with an indented aperture 24 to minimize wastage of material.
- the plug 16 further includes a circumambient wall portion 24 in spaced relation thereto and connected to the plug 16 by a short radial flange 28, whereby the plug 16, flange 28 and wall portion 26 together define an annular recess or groove about the plug 16.
- top or upper terminal portions of the tubular body 22, webs 24, and the wall 26 together define a common planar surface 30 on the neck 10.
- the aforesaid top planar surface 30 thereby defines several dispensing orifices 36 which in the preferred embodiment of the invention partake of an arcuate configuration.
- the orifices 36 inwardly thereof comprise elongated flow passages 38 or dispensing ports through which the product is expelled upon collapse of the container body portion 12 in usual manner.
- the upper surface is planar, and in particular comprises a sheared surface thereby to define a positive and precise planar relation between the neck element portions and the dispensing orifices 36.
- FIG. 4 relates to certain steps in the fabrication of the neck element of the present invention.
- a full disclosure of the novel forming and fabricating technique will be found in our aforesaid copending application Ser. No. 869,675.
- the neck 10 includes an obturation portion 0 which blocks the dispensing passages 38 between the webs 20.
- the center plug 16 includes an undesirable sprue extension S.
- the unwanted portions 0 and S are removed from the neck and at the same time the desired planar sheared surface 30 is formed on the neck 10 as by means of a reciprocable and rotatable knife assembly K which includes lower knife K1 and upper knife K2.
- the molded neck element 10 (which may at this time have been associated with container body 12) is elevated from the tool member T, after which the knife member K is laterally translated to cause the upper knife K2 to sever the sprue extension S as seen in phantom lines to the right in FIG.
- planar sheared surface 30 as aforesaid to positively open the passages 38 between webs 20 and define precisely formed right-angular dispensing orifices 36, thereby promoting smooth flow of the product in pressure dispensing from the container.
- the neck element of the invention is formed by injection molding which permits the precision of contour and dimensional tolerance which cannot be achieved by other molding techniques, such as blow molding, thermoforming, etc.
- the neck element 10 comprises an injection formed member of precise dimensional characteristics having the sheared surface 30, which defines the dispensing orifices 36 and which by virtue of the spacing of the dispensing orifices as above discussed, insures the cleanly formed and planar characteristics of the neck construction thereat.
- the neck as formed further includes the conical surface 40 surrounding the upper narrow portion of the center plug 16 as well as a comparable conical portion 42 at the upper end of the tubular portion 22 of neck element 10. As is well known, these conical surfaces cooperate with the closure C to insure a positive and leakproof seal when the cap or closure is in its closed and sealed position.
- a neck element for a center-lock captive closure comprising:
- annular wall portion disposed in circumambient spaced relation to said plug, said wall portion at its lower end being inturned toward said plug intermediate the plug length and integrally connected therewith, thereby to support said wall portion in spaced relation to said plug and define an annular recessed area therebetween, and,
- the neck element of claim 1 further including an integrally formed shoulder flaring outwardly from the lower end of said tubular portion.
