Benefits of technology

The present invention provides a packaging assembly that can accommodate a wide variety of containers and caps while maintaining a low variation in cap opening torques. The assembly allows a residual liquid composition to flow back from its opening to container easily and efficiently after dispensing, preventing it from accumulating and drying. The assembly also includes several components that serve as a visual reminder to users of the most efficient way in dispensing the liquid composition. Additionally, the assembly facilitates precise dosing of liquid compositions, particularly concentrated liquid compositions.

Problems solved by technology

However, such viscous liquid detergents pose challenges to packaging due to the increased difficulty in dispensing them out of the packaging along with the increased viscosity.
For example, the flow rate of the liquid detergent may become too slow to be acceptable by users, or the liquid detergent may form bulks which then block the opening of the packaging.
However, a liquid detergent may flow out of such a slotted spout too fast, thereby causing undesirable turbulence.
Moreover, a fast flow rate of the liquid detergent causes insufficient ventilation, i.e., not sufficient air could ventilate into the container at the same time when the liquid detergent is dispensed out of the container.
Therefore, the flow may undesirably stop or at least have discontinuous flow during dispensing due to the significantly decreased air pressure in the container.
But in the art the size and position of the vent are not aligned well with the spout such that the ventilation function of the vent is not consistently reliable, i.e., during dispensing a liquid detergent may flow out of the vent too.

Packaging Assemblies of the Present Invention

[0075]Example 1A is the packaging assembly as shown in FIG. 6. Specifically, the container of Example 1A has an internal volume of 2000 mL, and the cap of Example 1A has an internal volume of 80 mL. The transition piece as used in Example 1A is exactly the same as the one shown in FIGS. 2A, 2B, and 2C. The spout opening of the transition piece has a cross-sectional area of about 177 mm2, and the vent has a cross-sectional area of about 30 mm2. The spout has a length of about 55 mm measured from its base end to the spout opening along the longitudinal axis.

[0076]The packaging assembly of Example 1B comprises the same container and cap as Example 1A, but has a slightly different transition piece. The 3rd transition piece (from left) as illustrated in FIG. 7 is the one used for Example 1B. This transition piece has a circumferentially integral spout opening and 5 tiny vents arranged side-by-side. The spout opening therein has a cross-section...

Abstract

A packaging assembly (10) having a container (100) and a transition piece (200), which comprises a spout (201) with a circumferentially integral opening (204) and a vent (209) located adjacent to the base end (202) of the spout (201). The spout (201) and the vent (209) have a particular ratio in terms of cross-sectional area. The packaging assembly (10) provides a controlled dispensing of a liquid detergent composition, particularly viscous liquid detergent compositions.

Description

FIELD OF THE INVENTION[0001]The present invention relates to a packaging assembly. The present invention also relates to a liquid detergent product comprising a packaging assembly and a liquid detergent composition contained within the packaging assembly.BACKGROUND OF THE INVENTION[0002]Liquid detergents have been increasingly preferred by users over solid detergents, mainly due to their improved water solubility during a washing cycle. Moreover, viscous liquid detergents (e.g., a liquid detergent composition with a viscosity of 500 centipoise (“cps”) when poured out of a container) are desired as they tend to connote a premium product. However, such viscous liquid detergents pose challenges to packaging due to the increased difficulty in dispensing them out of the packaging along with the increased viscosity. For example, the flow rate of the liquid detergent may become too slow to be acceptable by users, or the liquid detergent may form bulks which then block the opening of the pa...
