Detailed Description of Frt jferr<gd Emb dimeEts

FIG. 1 illustrates a product 10 in accordance with an illustrative embodiment of the disclosure as including a container 12 to hold a liquid product P, and a dispensing fitment 14 coupled to the container 12. The fitment 14 may be non-removably secured to the container 12. The tennmoiogy "non-removably secured" includes a manner in which the fitment 14 is, by design-intent, not intended to be removed from the container 12 without damaging the container and/or fitment 14 or otherwise visibly compromising the structural and or functional integrity of either or both, Also, the fitment 14 may render the container 12 non-refillable. In other words, the fitment 14 may prevent or at least impede efforts to refill the container 12, for example, with counterfeit liquid products. The terminology "non-refillable" is used interchangeably herein with the terms refill- resistant and anti-refill, and includes a characteristic of the fitment 14 which, by design intent, is not intended to be refilled without dainaging the container 12 and/or fitment 14 or otherwise visibly compromising the structural and/or functional integrity of either or both. As will be described below, the fitment 14 also may facilitate evidencing of efforts to tamper with the product 10, for example, via breakage of the container 12 when someone attempts to refill the container 12.

The container 12 can be a bottle, for example, a wine or spirits bottle or any other suitable type of bottle or container, and can be composed of glass, ceramic, metal, plastic, or any other suitable material(s). The container 12 may include a bottom or base 18, a body 16 that may include a sidewall 20 extending in a directional axiaily away from the base 18 along a central longitudinal axis A of the container 12, The container 12 also may include a shoulder 22 extending in a directional axially away from, the sidewall 20. and a neck 24 extending in a directional axially away from the shoulder 22 and including a neck finish 26, As used herein, directional words such as top, bottom, upper, lower, radial, circumferential, lateral, longitudinal, transverse, vertical, horizontal, and the like are employed by way of description and not limi tation. The neck finish 26 may include an open end or mouth 28 of the container 12, and one or more closure engagement, elements 30, for example, helical threads, or any other suitable feature(s), for coupling to a closure (not shown). The geometry of the container 12 of FIGS. 1 and 2 is illustrative only, and any other suitable geometries m&y be used.

With reference to FIG. 3, the container neck 24 may include an interior passage 32 to carry the fitment 14 and to communicate liquid out of the container body 16 (FIG . 1) and through and out of the neck 24. The passage 32 may include a through bore 34 and a cotmterbore 36 in which the fitment 14 may be positioned. The bores 34, 36 may be of cylindrical shape or of any other suitable geometry, and may be established by interior surfaces of the container neck 24. An internal shoulder or step 38 may be established between the bores 34, 36 and may serve as an axial locator for the fitment 14.

Various features of the fitment 14 illustrated in the drawing figures are illustrative only, and may be of any other suitable type or construction. The fitment 14 includes an axially extending circumferential outer wall 40 to contact the interior passage 32 of the container 1.2. The outer wall 40 may be a ring or ring-shaped, for example of oval or cylindrical shape, or of any other suitable shape corresponding to the shape of the corresponding portion of the container neck 24, The outer wall 40 may contact an axial stop portion of the container 12, for example, the step 38. The fitment 14 also may include a base wall 42 that extends transversely with respect to the outer wall 40. As used herein, the term transverse may mean disposed at some non-zero angle with respect to the longitudinal axis A of the container 12 and along any direction intersecting the container 12 and may include but is not limited to a radial direction.

The relationship between the fitment 14 and the container 12 may be such that an axial end of the fitment 14 extends axially out the mouth 28 of the container 12 axially beyond an axial end surface or lip of the container 12 to form an anti-drip edge or feature. For example, the fitment outer wall 40 may have an axial length such that it bottoms out at the internal shoulder 38 in the container 12 and extends out of the container mouth 28.

The fitment 14 further may include any suitable features to impede or prevent refilling of the container 12. For example, the fitment 14 may include a check valve that may be Carried within the outer wail 40, for example, as illustrated in FIGS. 3 and 4. The check valve may include an outlet wall 44 having outle apertures 46, and a cage 48 held between the base and outlet walls 42, 46 and spaced from the outlet wall 44 by a spacer 50 and having apertures 49. The outlet wall 44 may be recessed axiall from the outer axial end of the outer wall 40 to provide anti-drip functionality. The check valve also may include a valve plate 52 axially movably retained by the cage 48 and covering an opening 54 hi the base wall 44, and a valve ball 56 retained between the cage 48 and the valve plate 52. The aforementioned elements may be mounted within and to the outer wall 40 of the fitment 14 in any suitable manner, in one embodiment the fitment 14 outer wall 40 may be composed of stainless steel or any other suitable metal, and one or more of the other portions of the fitment. 14 may be composed of plastic, metal, or glass. In other embodiments, one or more portions of the fitment 14 may be composed of glass or ceramic. For example, the outer wall 40, axial wall 44, cage 48, and/or ball 56 may be composed of glass or ceramic. Accordingly, attempts to remove the fitment 14 may shatter the container 12 and/or the fitment 14.

The illustrative cheek valve permits flow of liquid out of the container body 16 (FIG. 1) but prevents or retards flow into the container body 16. For example, the valve ball 56 holds the valve plate 52 down to cover the base wall opening 54 to prevent flow therethrough. But when the container 12 is tipped or inverted, liquid may flow ^" through the base wall opening 54 to displace the valve plate 52 and ball 56, and the liquid may flow out of the cage apertures 49 through the fitment 14 and out of the outlet openings 46. Non-refillable fitments are well known to those of ordinary skill in the art, and any suitable type of fitment may be used, whether a check valve type of fitment, an ai r trap type of fitment, or any other suitable type of refill-resistant fitment.

With reference to FIG. 5, the fitment 14 also may include decorative and/or informative features. For example, the outer wall 40 of the fitment 14 can carry indicia, for example, brand name indicia 58, package serial number indicia 60, a logo, a slogan, or the like, in another example, the features may include a radially recessed portion in the wall 40 that may extend axially and circumferentially, and may be rectangular in outer profile or of any other suitable shape. In one embodiment, the indicia may be disposed within the radially recessed portion and may project radially outwardly, as shown, or may be recessed, or printed, or the like. In another embodiment, the indicia may be carried on the fitment outer w ^r all 40 and may be engraved or otherwise radially recessed in the outer wall 40, may be printed thereon, or the like. The various features may be formed, machined, lasered, etched, or produced in an other suitable manner. The features may be located on the fitment 14 in such a manner that the features are disposed completely within the container neck 24 below an axial end surface or lip of the container neck 24. Accordingly, the decorative and/or inibrmaiive features are positioned on the inside of the container but are visible therethrough.

In production, a liquid product may be flowed into the container 12 in any suitable manner, and then the fitment 14 can be coupled into the neck 24 of the container 12 via an interference fit to render the product 10 tamper-evident. The fit between the outer wall 40 of the fitment 14 and the corresponding interior surface of the container 12 may be tight, wherein the fitment 14 cannot be removed without causing visible damage to the container 12. For example, the outer wall 40 of the fitment 14 may he larger than the corresponding interior surface of the container 12 that carries the fitment 14 when both the fitment 14 and the container 12 are at the same temperature,

In one embodiment, before assembly, the fitment 14 may be at a relatively cooler temperature than the container 12. hi one example of this embodiment, before assembly, the fitment 14, or at least the outer wall 40 of the fitment 14, can be cooled to reduce the radially outer size of the outer wall 40 and the container 12, or at least the corresponding wall thereof, can be heated to increase its radially inner size. Then, the fitment 14 can be inserted into the container 12 to its desired axial, position, and then as the fitment 14 warms up and the container 12 cools down, the radially outer size of the outer wall 40 expands into a tight fit with the corresponding contracting portion of the container 12.

in other embodiments, only the fitment 14 may be cooled, or only the container 12 may be warmed, and then the fitment 14 may be assembled to the contarner 12. Thereafter, expansion of the fitment 14 or contraction of the container 12 result in the interference fit. In another embodiment, the fitment 14 may be press fit to the container 12. For example, the fitment 14 and the container 12 may be at the same or similar temperature, and the fitment 14 pressed into the container 12. Of course, care must be taken in the selection of the materials, wall thicknesses, and the like, to ensure that the hoop stresses are not so high that such press fitting breaks the container 12.

In a further embodiment, any combination of the aforementioned embodiments may be used.

it is believed that friction and/or surface tension between the fitment and the container resulting from the interference fit will sufficiently secure the fitment in place and render the fitment tamper-evident because attempts to remove the fitment should result in visible damage or breakage of the container and/or fitment. But other engagement features could be added such as barbs on the exterior of the fitment that could press into certain container materials, like plastic, and cause visible damage to the container if the fitment were removed or removal was attempted.

A method of inserting an anti-refill valve into the neck of a container may include the following steps: providing a container having a neck at a first temperature, mounting an anti-refill valve within a ring, providing the ring at a second temperature less than the first temperature, inserting the ring with anti-refill valve into the neck of the container, and allowing temperatures of the container neck and the ring to equalize to secure the ring and the valve within the neck. The ring may include the outer wall 40 of the fitment 14, and the anti-refill valve may include the various other elements of the fitment 14. Equalization of temperatures of the ring and/or container neck may occur passively over time, or may be actively accelerated by any suitable heating and/or cooling operation(s). Of course, artisans of ordinary skill will recognize that the relative cooling and warming temperatures are application specific, and dependent on material selection, wall thicknesses diametric interference, and the like.

if, as they are known to do, counterfeiters attempt to melt a plastic portion of the fitment 14 by a pplyin g heat to the fitment 14, the outer wall 40 of the fitment 14 will expan d and, thus, break the container neck 24, thereby faci litating evidence of tampering with the container 12 and likely rendering the container 12 unusable, The container 12 and/or fitment 14 would break because the portion of the fitment 14 expands to a greater extent than the container 12 for a given temperature and, thus, the expanding fitment 14 would stress the container 12 beyond its breaking point,

FIG. 6 illustrates another illustrative embodiment of a product 110 including a container 112 and a fitment 114 non-removably coupled to the container 112. This embodiment is similar in many respects to the embodiment of FIGS. 1-5 and like numerals between the embodiments generally designate like or corresponding elements throughout the several views of the drawing figures. Accordingly, the descriptions of the embodiments are incorporated into one another. Additionally, the description of the common subject matter generally may not be repeated here.

In this embodiment, the container 112 includes a neck 124 including a neck finish 126. The neck finish 126 may include an open end or mouth 128 of the container .1 12. The container neck 124 may include an interior passage 132 to carry the fitment 1 14. The passage 132 may, but need not, take the form of a counterbore passage. For example, the passage 132 may include a through bore 1 34, a counterbore 136 in which the fitment 1 14 may be positioned, and an internal shoulder or step 138. The fitment 114 includes an axially extending radially outer wall 140 to contact the interior passage 132 of the container 112, The outer wall 140 may contact an axial stop portion of the container 112, for example, the step 138. The fitment 114 also may include a frusto-eomeal or tapered surface 141 between interior and exterior circumferential surfaces of the fitment 114 and at an interior end of the fitment 114. Accordingly, the tapered surface 141 may terminate in a relati vely thin or sharp edge. The tapered surface 141 discourages attempts to remove the fitment 114 by hooking of the interior end of the fitment 1 14. The fitm ent 114 may be a simpl e annular component, as shown in FIG. 6, for example, to provide an anti-drip feature to the container 112. But the fitment 114 instead may include non-refillable features and functionality and, thus, may carry other components, for example, as shown in FIGS. 1-5.

FIG. 7 illustrates another illustrative embodiment of a product 210 including the container 112 and a fitment 214 non-removably coupled to the container 112. This embodiment is similar in many respects to the embodiments of FIGS. 1-6 and like numerals between the embodiments generally designate like or corresponding elements throughout the several views of the drawing figures. Accordingly, the descriptions of the embodiments are incorporated into one another. Additionally, the description of the common subject matter generally may not be repeated here.

in this embodiment, the fitment 214 includes an axially extending circumferential outer wall 240 to contact the interior passage 132 of the container 112. The outer wail 240 may include a tapered surface 241 between interior and exterior circumferential surfaces of the fitment 214 and at an interior end of the fitment 214. The outer wall 240 of the fitment 214 also may include one or more engagement elements, for example, thread segments 215, for coupling other components or devices to the fitment, such as an aerator, an anti-refill device, or any other suitable products. As ed herein,. the terra thread segment includes w ole, arti ij jto!ti k, andor an interrupted thread. mdiw ttead segment The Strneat 114 tm he a simple annular ¾Q«j- oaen as shown in FI3, 7 _S for example, to o ide a coupling and/or anti-drip feature to di container 112,.. But the fitment 214 instead may other components, for example, as shown in FIOS, 1-5,
