This invention relates to the field of containers and their methods of manufacture. This invention further relates to one-piece containers with multiple design elements.
Bottles for storing and dispensing liquids are known in the art. Many bottle types exist, being made of different materials and configurations. The mechanisms by which bottles store and dispense fluids have become more and more complex as the end user expects additional benefits. These benefits include repeatably removable caps, spouts, caps functioning as dosing cups, drainback features, and the like. These items have resulted in more complexity in the bottle. In turn, these additional complexities result in an increasing complex manufacturing process. These complexities require bottles having multiple parts, including mechanisms for attaching a cap, glue rings, elements for force fitments, and the like. These items must be put together in what is often a multistep process, adding additional cost and complexity.
Blow-molded polyethylene phthalate (“PET”) bottles are also known in the art. PET bottles have been used multiple industries because of their ease of manufacture, low resin costs, and recyclability. While the technology for producing fairly simple PET structures is known, the addition of additional elements has been difficult. Specifically, adding elements such as a spout or drainback feature within the structure of a PET bottle has been possible with available technologies.
What is needed is a bottle capable of delivering various benefits with little or no additional manufacturing complexities. The current invention delivers these objectives.

In one embodiment there is a bottle comprising a body capable of containing a fluid; a spout fluidly connected to the body; a collar comprising at least one attachment area, said collar capable of removably securing a cap; a skirt functionally connected to the collar; and a drip concentrator concentrically interposed between the spout and the collar; wherein the bottle is continuous. In one embodiment, the skirt visually engages with the body.
In an alternate embodiment, there is a preform comprising a tubular body capable of being molded; a spout fluidly connected to the tubular body; a collar comprising at least one attachment area, said collar capable of removably securing a cap; a skirt functionally connected to the collar; and a drip collector concentrically interposed between the spout and the collar; wherein the preform is continuous.
The term “one piece” or “continuous” as used herein, means that the preform or the bottle is made of one continuous piece of material, without the need for joining by welding, adhesive, heat seals, mechanical means, or other processes. The term “multi piece” as used herein, means that the preform or the bottle is made of more than one piece of material.
The term “substantially” as used herein, means a dimensional change of less than about 5%. For example, two objects having substantially the same volume would have actual volumes differences of less than about 5%.
The term “vent” as used herein, means an opening in the drip concentrator capable of allowing a fluid to pass through. The vent can be fully surrounded by the drip concentrator, e.g., a hole or circular shape within the drip concentrator. The vent can also be partially surrounded by the drip concentrator, e.g., a notch or cutout. Alternatively, the fluid pathway from the spout to the body of the bottle may be considered the vent.
The term “visually engage” as used herein, means for a structure to contact or to nearly contact (less than about 5 mm, alternatively less than about 2 mm) a second structure whereby the two structures have the appearance of being sealed, closed, or otherwise engaged with each other without additional processing steps including welding, adhesives, heat seals, mechanical means, and the like.
The term “fluid” as used herein, means any substance that is capable of being poured. Fluids of the present invention include both liquids, fluidizable solids or powders, and granular compositions that are capable of being poured.
It has been found that a bottle comprising is a bottle comprising a body capable of containing a fluid; a spout fluidly connected to the body; a collar comprising at least one attachment area, said collar capable of removably securing a cap; a skirt functionally connected to the collar; and a drip concentrator concentrically interposed between the spout and the collar; wherein the bottle is continuous provides the benefit of an inexpensive bottle that is constructed with fewer steps in fewer pieces.
Without wishing to be bound by theory, it is believed that the bottle of the present invention allows for a bottle containing various elements, including a drip collector, spout, skirt, collar, and the like to be constructed as a one piece bottle with reduced processing and assembly. Moreover, various elements may be added or removed depending on the desired end function of the bottle, allowing for custom application bottles. Spout shape can be non round (v shape or elliptical) and may not need to be a complete circle.
It is contemplated that the process for moving from the preform to bottle utilizes blow molding techniques, such as stretch blow molding. Such techniques are well known in the art. While these techniques are well known, utilizing blow molding to produce the bottle of this invention is unique, as having a bottle with the elements disclosed herein has before been unattainable.
Various plastics materials are suitable, including polyvinyl chloride, high and low density polyethylene, polypropylene, acrylic, polystyrene, or polycarbonate. Since the one-piece construction offers savings, more expensive materials such as polyethylene terepthalate (PET), polyethylene napthalate (PEN) and copolymers and blends of these two materials in both crystalline and amorphous forms are viable.
In one embodiment, the resin of the present invention is manipulated to form a preform. An exemplary preform of the present invention is illustrated in
In one embodiment, the preform is made from one piece. Such a one piece preform has the advantages of incorporating various elements without additional manufacturing or processing steps. The mold for a one piece preform is such that a desired preform can be made by injecting resin into the preform mold in one processing step. Such a preform, when made into a bottle or container forms a continuous or one piece bottle.

The head 2 of the illustrated preform 1 contains a spout 30, collar 20, skirt 40, and a drip concentrator 24. The tubular body 10 is fluidly connected to the spout 30. In one embodiment, the spout 30 and tubular body 10 are oriented to allow the insertion of a blow pin used during a blow molding process. The spout 30 functions to direct the liquid out of the fully blown bottle. Typically, the spout extends in length beyond the collar 20 to prevent buildup of product inside of the head 2. The spout 30 extending beyond the collar 20 allows pouring of contained product into a dispensing cup.
The drip concentrator 24 is concentrically interposed between the spout 30 and the collar 20. The drip concentrator 24 functions to gather any product remaining in the closure (e.g., dispensing cup) upon reapplication of the closure. The drip concentrator 24 further contains a vent 26. The vent 26 allows any product captured by the drip concentrator 24 to be collected within the blown bottle. In one embodiment, the drip collector is oriented in a non-parallel orientation to the rim 29. Without wishing to be bound by theory, it is believed that this non-parallel orientation of the drip concentrator 24 facilitates fluid transport of the material on the drip concentrator 24 through the vent 26 into the blown bottle.
The collar 20 is functionally attached to the drip concentrator 24. The collar further comprises an attachment area for engaging a cap, lid, top, or other sealing mechanism. An attachment area of the current invention includes threads 22. Threads 22 are present on the inside of the collar 20. The threads 22 are designed to engage with a cap for sealing the contents of the blown bottle. While threads 22 are illustrated here, other engagement mechanisms are also contemplated. Such engagement mechanisms would be readily known by one of skill in the art. For example, the orientations of threads 22 on the collar 20 can also be placed on the outside of the collar 20, instead of the internal position illustrated.
In one embodiment the rim 29 of the collar 20 serves at least one sealing function. When blow molding the preform into a bottle, the rim 29 at least partially engages with the blow pin forming a seal, facilitating blow molding. Upon completion of the blow molding, the collar 20, when engaged with a cap forms at least a partial seal with the rim 29 when engaged. The skirt 40 is functionally connected to the collar 20. The skirt 40 optionally comprises a flute 42 on an end of the skirt 40. The flute 42 may be curved, angled, straight, or shaped otherwise to allow for visual engagement of the skirt 40 with the body 10 after the blow molding step.
In one embodiment, the skirt 40 visually engages the body 110, as further exemplified in
In an alternate embodiment, not illustrated, the skirt can be molded separately and introduced onto the bottle, forming a multi-piece bottle. In such an embodiment, the skirt and body are made of the same material or optionally different materials.
As the preform of the present invention contains many different elements, proper orientation of these elements is desired when blow molding the preform into the bottle. Such a feature is of particular importance when the body 110 is not cylindrical, but has a length longer than its width. Proper orientation of the preform in the blow mold can be achieved utilizing an optional orientation notch 46, illustrated on the preform. Such an orientation notch 46 is capable of aligning with machinery capable of processing the preform 1, such as blow molding machines, conveyers, and the like.
