## Background
CROSS-REFERENCE TO RELATED APPLICATION
This application claims priority to U.S. Provisional Patent Application Ser. No. 62/011,603 filed Jun. 13, 2014, hereby incorporated herein by reference in its entirety.


FIELD
The present technology relates to a nozzle and cap assembly and more particularly to a dual thread nozzle and cap assembly for a pouch that dispenses a confectionery used in the decoration of cakes and cookies, for example.
INTRODUCTION
The application of flowable confectionery or icing to the top and sides of an iced cake or other pastry is well known in the art. Typically, the confectionery is sufficiently viscous to maintain a shape and is resistant to excessive flow or slumping after being extruded or dispensed from an associated bag or dispensing pouch. Some types of flowable confectionery may tend to surface harden by reason of water evaporation after being dispensed from the pouch. Accordingly, it is desirable that the pouch and the dispensing system be substantially leak-proof and air tight to prevent evaporation of water and the resultant hardening of the contents prior to application. Certain flexible and collapsible dispensing pouches utilized for decorating cakes and other pastries employ a dispensing nozzle, through which a flowable confectionery such as cake icing may be extruded. An example of a dispensing system is shown and described in U.S. Pat. No. 6,981,614, the contents of which are hereby incorporated herein by reference.
Dispensing pouches are usually adapted to receive a decorating tip either alone or with a cooperating collar or compression ring that engages a threaded portion of the dispensing nozzle to hold the decorating tip in place. The flowable confection is caused to be extruded through the decorating tip by collapsing the dispensing pouch and applying pressure thereto. The shape of the free end of the decorating tip determines the final shape of the extruded confection.
In order to create extruded designs of a different type or size, use of a different decorating tip is required. This may require that a different nozzle tip assembly be used, thereby exposing the confectionery stored in the dispensing pouch to air, resulting in drying and surface hardening. Certain nozzle and cap assemblies accept decorating tips of different sizes and shapes to allow interchanging of the decorating tips such as shown and described in U.S. Pat. No. 7,762,439, the contents of which are hereby incorporated herein by reference, and U.S. Pat. No. 7,337,923, the contents of which are hereby incorporated herein by reference. However, the nozzle and cap may not effectively cooperate with each other to maintain a hermetically sealed nozzle. For example, as assembled, a space typically exists between the nozzle opening and the cap to militate against damage to the nozzle opening. Therefore, confectionery can leak intermediate the nozzle and cap and succumb to hardening and/or the confectionery within the dispensing pouch or nozzle can harden and cause clogging of the nozzle and decorating tips. Additionally, some nozzle and cap assemblies require multiple parts, additional molded features, and components, which undesirably leads to higher manufacturing costs.
Therefore, it would be desirable to improve nozzle and cap assemblies for a dispensing pouch to facilitate effective sealing and militate against a complexity and cost of manufacturing.

In FIGS. 1-4, a nozzle and cap assembly 10 adapted to be joined with a container is shown. The nozzle and cap assembly 10 includes a unitary hollow nozzle 12 and a cap 14. The cap 14 cooperating with the nozzle 12 to seal the nozzle 12.
The nozzle 12 includes a radially outwardly extending collar 16 formed at a first end 18 of the nozzle 12 and adapted to be joined with the container, such as a dispensing pouch 100 as shown in FIG. 6. The nozzle 12 further includes a first threaded section 22 and a second threaded section 24 formed at a second end 20 thereof. The threaded sections 22, 24 are formed on an outer surface of an annular wall 28 of the nozzle 12 and are concentrically aligned with each other. A diameter of the first threaded section 22 is less than a diameter of the second threaded section 24. In certain embodiments, a flange 26 is disposed intermediate the second threaded section 24 and the collar 16. The annular wall 28 defines an aperture 30 that extends through the nozzle 12 from the second end 20 to the first end 18 thereof. The annular wall 28 terminates at a substantially planar rim 31 formed at the second end 20 of the nozzle 12.
The cap 14 has an open end 34, a closed end 36, a first annular wall 40 disposed adjacent the closed end 36, and a second annular wall 42 disposed adjacent the open end 34. The closed end 36, the first annular wall 40, and the second annular wall 42 define a cavity 38 configured to receive the first threaded section 22 and the second threaded section 24 of the nozzle 12. In the embodiment shown in FIG. 4, threaded portions 44 are formed on the inner surface of the first annular wall 40 and the inner surface of the second annular wall 42. The threaded portions 44 are configured to correspondingly releasably engage with the first threaded section 22 and the second threaded section 24 of the nozzle 12 to couple the cap 14 to the nozzle 12. A diameter of the first annular wall 40 has a diameter substantially corresponding to a diameter of the first threaded section 22 and a diameter of the second annular wall 42 has a diameter substantially equal to the second threaded section 22. Additionally, a height of the first annular wall 40 has a height substantially corresponding to a height of the first threaded section 22 and a height of the second annular wall 42 has a height substantially equal to a height of second threaded section 22. It is understood that the cap 14 can be coupled to the nozzle 12 by other means as desired such as with an interference fit, for example.
The nozzle and cap assembly 10 further includes a ring 32 having notches 33 formed therein disposed intermediate the open end 34 of the cap 14 and the collar 16 of the nozzle 12. The ring 32 is configured as a tamper evident indicator. The ring 32 may be coupled to the cap 14 by frangible elements (not shown). The ring 32 is positioned about the flange 26 and secured thereto by a snap fit, friction fit, or other similar coupling means. In certain embodiments, tabs 48 extend outwardly from the cap 14 and are adapted to engage with the notches 33 of the ring 32 to facilitate stability and to maintain the frangible elements in position during an initial assembly of the nozzle and cap assembly 10.
The nozzle and cap assembly 10 can further include sealing features to facilitate sealing of the nozzle 12. For example, in certain embodiments, the cap 14 further includes a lip 46 formed on the second wall 42 at the open end 34 thereof. The lip 46 is adapted to align with the ring 32. In another example, as shown in FIG. 4, an annular protrusion 50 is formed on the inner surface of the cap 14 at the closed end 36 thereof. The annular protrusion 50 has an outer diameter substantially equal to a diameter of the aperture 30 of the nozzle 12. In yet a further example, surface roughening means 52 can be formed on an outer surface of the cap 14 to facilitate gripping the cap 14 such as grooves or protrusions, for example.
During assembly, the cap 14 receives the nozzle 12. The threaded portions 44 of the cap 14 threadingly engage with the first threaded section 22 and the second threaded section 24 of the nozzle 12. When the cap 14 is engaged with the nozzle 12, the rim 31 interfaces the inner surface of the cap 14 to facilitate hermetically sealing the aperture 30 of the nozzle 12. The annular protrusion 50 cooperates with the inner wall of the cap 14 to form a channel. The channel is configured to receive and guide the rim 32 of the nozzle 12 to interface with the inner surface of the cap 14. The annular protrusion 50 extends into the aperture 30 and interfaces the inner surface of the annular wall 28 of the nozzle 12. In certain embodiments, during an initial assembly, prior to the cap receiving the nozzle 12, the ring 32 is coupled to the cap 14 via the frangible elements, wherein the tabs 48 of the cap 14 engage with the notches 33 of the ring 32. Thereafter, the cap 14 and ring 32 are then positioned over the nozzle so that the ring 32 is positioned about the flange 26 of the nozzle 12.
In FIG. 5, a nozzle and cap assembly 10′ according to another embodiment of the disclosure is illustrated. Features similar to the nozzle and cap assembly 10 illustrated in FIG. 1 are denoted with the same reference numeral and a prime (′) symbol for clarity. The nozzle and cap assembly 10′ of FIG. 5 is similar to the nozzle and cap assembly 10 of FIGS. 1-4, except the nozzle and cap assembly 10′ includes a hanger tab 60 disposed at the closed end 36′ thereof and extending outwardly from an outer surface thereof. An aperture 62 is formed in the hanger tab 60. The hangar tab 60 is configured for hanging or displaying the dispensing pouch 100 at a store, for example.
In FIG. 6, an exemplary embodiment of the nozzle and cap assembly 10 coupled to the dispensing pouch 100 is shown. The dispensing pouch 100 such as shown and described in U.S. Pat. Appl. Pub. No. 2003/0205584, which is hereby incorporated in its entirety herein, is configured for containing and dispensing confectionery. In application, the nozzle and cap assembly 10 is joined with the dispensing pouch 100 by joining the collar 16 with an open end of the dispensing pouch 100. The nozzle and cap assembly 10 can be joined with the dispensing pouch 100 by heat sealing or gluing to form a leak proof seal therebetween. The nozzle and cap assembly 10′ of the embodiment shown in FIG. 5, can be similarly coupled to the dispensing pouch. The dispensing pouch 100 can further include an aperture 102 formed therethrough for hanging the dispensing pouch 100.
During an initial use, the cap 14 is removed from the ring 32 and nozzle 12 by breaking the frangible elements and disengaging the threaded sections 22, 24 of the nozzle 12 from the threaded portions 44 of the cap 14. To dispense or extrude a confectionery from the dispensing pouch 100 through the aperture 30 of the nozzle 12, pressure is applied to the outside of the dispensing pouch 100 by a user. A variety of selected tips, not shown, can threadingly engage with the first threaded section 22 or the second threaded section 24 of the nozzle 12 to create shapes and sizes of extruded confectionery as desired. After extruding confectionery, the selected tip can be removed from the nozzle 12. The cap 14 is then positioned to threadingly engage with the nozzle 12 so that the inner surface of the cap 14 interfaces the rim 31 of the nozzle 12 to hermetically seal the aperture 30 of the nozzle 12 after use. The nozzle 12 and cap 14 cooperate with each other to militate against hardening of the confectionery within the dispensing pouch 100 or nozzle 12 or between the nozzle 12 and the cap 14. If an additional use of the dispensing pouch is desired, the cap 14 can then be removed again by disengaging the threaded sections 22, 24 of the nozzle 12 from the threaded portions 44 of the cap 14.
The nozzle and cap assembly 10, 10′ can be formed from any suitable material such as a plastic material by a molding process such as injection molding. However, the nozzle and cap assembly 10, 10′ can be formed from any material having properties suitable for assisting in dispensing confectionery and by any process now known or later developed.
The nozzle and cap assemblies 10, 10′ of the present disclosure minimize cost and complexity of manufacturing while facilitating an effective seal of the confectionery within the dispensing pouch 100. The nozzles 12, 12′ are configured to receive any standard decorating tips as desired, such as Wilton brand decorating tips, DEC-A-CAKE brand decorating tips, TONES BROTHERS brand decorating tips, CAKE MATE brand decorating tips, and BETTY CROCKER brand decorating tips, for example.
