Description

BACKGROUND OF THE INVENTION

Field of the Invention

The present disclosure relates to a method and apparatus for dispensing. The present disclosure relates more specifically to a spout assembly and a bottle assembly for dispensing.

Description of Related Art

A bottle is a rigid container with a neck that is narrower than the body and a mouth. By contrast, a jar has a relatively large mouth or opening which may be as wide as the overall container. Bottles are often made of glass, clay, plastic, aluminum or other impervious materials, and typically are used to store liquids such as water, milk, soft drinks, beer, wine, cooking oil, medicine, shampoo, ink, and chemicals. A device applied in the bottling line to seal the mouth of a bottle is termed an external bottle cap, closure, or internal stopper. A bottle can also be sealed by a conductive “innerseal” by using induction sealing.
A plastic bottle is a bottle constructed from plastic. Plastic bottles are typically used to store liquids such as water, soft drinks, motor oil, cooking oil, medicine, shampoo, milk, and ink. Plastic bottles have become popular with both manufacturers and customers due to their lightweight nature and relatively low production and transportation costs when compared with glass bottles. However, the biggest advantage plastic bottles have over glass, is their superior resistance to breakage, in both production and transportation.

DETAILED DESCRIPTION OF THE INVENTION

Embodiments of the present disclosure provide for a spout assembly that can be removeably attached to a bottle. For purposes of description, the bottle has a body and a mouth, wherein the mouth defines a termination of a neck and a shoulder interconnects the body to the neck. The neck thus has a dimension, or neck height, from the mouth to the shoulder. Embodiments further provide an integral spout assembly having an endless side wall that corresponds to the neck height of the bottle. Embodiments provide a dispensing assembly that includes a bottle with a spout that allows a user to substantially pour out all of the contents of the bottle. That is, as the side wall of the spout assembly does not project into the interior of the bottle substantially beyond the neck, there is no cavity formed by the shoulder of the bottle and side wall of the spout assembly which can retain contents upon inversion of the bottle. Embodiments still further provide a bottle with a removeable spout that prevents the build-up of the contents of the bottle between the bottle and the removeable spout along the spout neck. Aspects provide a removeable spout with a drainage trough and vertical ribs that prevent stacking or nesting of multiple spouts. Embodiments include a spout made of plastic with a wall thickness between approximately 0.036 inches to 0.1 inches. Embodiments include a bottle made of plastic with a wall thickness between approximately 0.036 inches to 0.1 inches.
Embodiments of the present disclosure include a spout assembly 102, which includes spout 104, trough 106, and side wall 108. The spout has a generally tubular configuration, wherein the cross section along a length of the spout can be constant or varied, as well as symmetrical or asymmetrical along a longitudinal axis of the spout. For purposes of description, the spout is described as cylindrical. However, it is understood the spout can have any of a variety of tubular configurations. Spout assembly 102 as shown in FIG. 1 is a cylindrical spout that has an endless wall that defines passage 110 through spout assembly 102. Spout 104 has a top open edge 112 fluidly connected to bottom open edge 114. Passage 110 fluidly connects the top open edge 112 and the bottom open edge 114 of spout 104. The top open edge 112 can lie in a single plane, or can occupy a given volume. Spout 104 includes multiple vertical ribs 116 extending inwardly from the endless wall within the passage 110.
Embodiments of spout assembly 102 include three vertical ribs 116 that serve at least two purposes. First, vertical ribs 116 are located along endless wall of spout 104 such that during use (such as pouring a liquid through spout assembly 102) the flow is directed along the longest portion of spout 104. In the embodiment shown in FIG. 1, the longest portion of spout 104 is enclosed by two of the three vertical ribs 116. Second, vertical ribs 116 provide a means that prevent stacking, clustering, or nesting of multiple spout assemblies 102 on top of one another during sorting, packaging, or assembly.
Embodiments of vertical ribs 116 include vertical ribs 116 that have the same thickness throughout their long axis that extends from the top open edge 112 to the bottom open edge 114. In other words, the distance vertical ribs 116 extend within passage perpendicular from the endless wall 110 is the same throughout the extent of vertical ribs 116. In another embodiment, vertical ribs 116 can have a different thickness or a thickness that gradually changes along its long axis. Further, the vertical ribs 116 can have different cross sectional profiles, either along a length of the rib or between ribs. Embodiments of vertical ribs 116 can have a cross sectional thickness of approximately 0.05 inches to 0.103 inches.
The bottom open edge 114 is connected to trough 106. Trough 106 circumscribes the bottom open edge 114. Trough 106 provides a means to trap and direct a flow of liquid from spout 104. Trough 106 has a flat surface that is angled towards a drainage hole 120. Thus, trough 106 directs a flow (through gravity) of liquid toward drainage hole 120 such that liquid drains back into a bottle to which spout assembly 102 is removeably attached. Drainage hole 120 can be located at many different locations along trough 106, however, embodiments of drainage hole 120 are located such that substantially all of a liquid that enters trough 106 is able to flow out of trough 106 through drainage hole 120. Embodiments of trough 106 can include one or more drainage holes 120.
Side wall 108 is coupled to trough 106 and extends around spout 104 thereby circumscribing spout 104. Embodiments of side wall 108 have a height that is equivalent to the neck height of the bottle to which spout assembly 102 is removeably attached. Embodiments of side wall 108 allow a flow of substantially all liquid from a bottle to which spout assembly 102 is removeably attached. In other words, embodiments of side wall 108 prevents a build-up of liquid between the bottle and side wall 108.
Side wall 108 includes an outwardly extending retaining bead 122 that engages the neck of the bottle and resists removal of spout assembly 102 from a bottle. Retaining bead 122 also allows spout assembly 102 to be affixed and removed from a bottle to which spout assembly 102 is attached with a predetermined force from either a user or a machine during manufacturing or assembly.
Side wall 108 also includes a lip 124 which extends outwardly perpendicular from side wall 108. Lip 124 substantially resists or prevents spout assembly 102 from being completely pressed inside a bottle. Lip 124 is configured to engage the mouth of the bottle to limit passage of the spout assembly and locate the spout assembly relative to the neck. Embodiments of lip 124 outwardly extends circumferentially from side wall 108 approximately 0.061 inches and has a height of approximately 0.036 inches.
Spout assembly 102 is operable to be removeably attached or permanently attached to a bottle 126 (shown in FIG. 8). Bottle 126 includes a body 128 and a neck 130. Body 128 defines a hollow cavity that is operable to maintain a fluid. Body 128 can also include a handle 132 to aid a user during use in pouring a fluid from body 128. Neck 130 is sized to correspond with side wall 108 of spout assembly 102 creating a sealed interface by a friction fit (intentional interference) between bottle 126 and spout assembly 102. Neck 130 includes a thread 134 that circumscribes an exterior of neck 130.
Neck 130 also includes a retaining shoulder 136 which extends perpendicular from the interior wall of neck 130. Retaining shoulder 136 circumscribes the interior portion of neck 130. Retaining shoulder 136 is operable for interacting retaining bead 122 of spout assembly 102 to aid in sealing the spout assembly to the bottle. When placing spout assembly 102 within neck 130 of bottle 126 retaining bead 122 is snapped or pushed over retaining shoulder 136. Then lip 124 of spout assembly 102 sits on the mouth. Thus lip 124 substantially prevents spout assembly 102 from completely passing through neck 130 into body 126.
As side wall 108 has a height substantially equal to, or less than, the height of the neck of the bottle, no pocket or cavity is formed between the outside of the side wall and the shoulder of the body. In other embodiments, side wall 108 is not uniformly distanced from the center of spout assembly 102, but has a radius distance from the center of spout assembly 102 that decreases gradually or uniformly toward the bottom of spout assembly 102 (shown in FIG. 14, FIG. 15, and FIG. 16). In these embodiments, side wall 108 with retaining bead 122 and neck 130 still creates a sealed interface by friction fit (intentional interference) near the top of neck 130, but the bottom portion of side wall 108 is not in contact with the interior of neck 130 of bottle 126. Thus, a pocket 138 is created between neck 130 and side wall 108. This allows for alternative manufacturing capabilities because of the self-centering aspects of spout assembly 102 combined with the decreased radius along the bottom of side wall 108, which allows for decreased machine error during insertion.
Embodiments of side wall 108 further include instances wherein the height of side wall 108 is not uniform through the circumference of side wall 108. For instance as shown in FIG. 16, embodiments of side wall 108 include the height of side wall 108 nearest the tallest portion of spout assembly 102 (also known as the pouring side) having the same height or substantially the same height as neck 130, and the opposite side of side wall 108 having a height that is greater than that of neck 130. In other words, side wall 108 has a height that substantially prevents a buildup of excess liquid between bottle 126 and spout assembly 102 between neck 130 and side wall 108 during proper use. Excess liquid between bottle 126 and spout assembly 102 along the pouring side drains to the pouring side and is thus not retained with in the bottle 126. That is, the pocket 138 (volume) defined between side wall 108 and neck 130 along the pouring side of the bottle 126 and spout assembly 102 is minimized with respect to the height of the neck 130 and side wall 108. The pocket 138 defined by the side wall 108 and neck 130 along the pouring side substantially defines the volume of retained material in the bottle 126. As the volume is minimized, the percentage of material dispensed from the bottle 126 to material introduced into the bottle 126 is increased.
Embodiments of spout 104 are located such that the longest portion of spout 104 is nearest to the adjacent side wall 108 relative other portions of spout 104. However, embodiments of spout 104 further provide that spout 104 is sufficiently spaced from side wall 108 such that after spout assembly 102 is affixed to neck 130 of bottle 126, spout 104 is positioned such that it does not interfere with or obstruct the ability to pressure check the seal between neck 130 and side wall 108. Embodiments of spout 104 are positioned such that an air tight seal can be formed along the top of neck 130 and side wall 108 allowing verification that air and liquid is substantially prevented from passing between neck 130 and side wall 108.
The present configuration effectively eliminates the pocket of the prior art by locating a bottom of the side wall at the bottom of the neck. Thus, upon tipping or inverting the bottle to pour from the spout assembly, substantially none of the material in the bottle is captured in a pocket between the spout assembly and the inside surface of the bottle. This allows a consumer to use more of the purchased material, thereby increasing value and decreasing waste.
