Definitions

  • the present invention relates to durable bottom-dispensing containers.
  • Liquid dispensers are widely used for various applications, including household products, personal care items, and industrial chemicals.
  • liquid dispensers have been designed with top dispensing mechanisms, where the liquid is dispensed through an opening on the top of the container.
  • top dispensing mechanisms where the liquid is dispensed through an opening on the top of the container.
  • a growing number of such products, and especially liquid detergent compositions are provided in bottom-dispensing containers, also sometimes referred to as inverted containers, since they provide less hold-up of product inside the container, and enable easy dispensing.
  • a particular challenge with these types of bottom-dispensing containers is the prevention of leakage of the liquid contained therein during steady state (i.e., storage) and/or upon impact, especially upon impact.
  • leakage may occur during storage when the inverted container is subjected to a temperature change, specifically increase (e.g., inverted container placed beside sunny window or near stove top, etc.), that can lead to internal pressure increases and leakage.
  • impact it is meant that when the inverted container is handled, transported, dropped or knocked over.
  • transient liquid pressure increases also referred to as hydraulic hammer pressure, inside the container and can momentarily force open the valve causing liquid to leak out, which will result in consumer dissatisfaction with the product.
  • impact resistance systems adds complexity to the process of making the package. In addition, they can be difficult to clean, especially when residual liquid contained within the container has dried. As such, such impact resistance systems are less suited for durable containers which are cleaned and reused regularly.
  • EP3686118A1 relates to a bottom dispensing package comprising a base having an orifice comprising a slit-valve, which is less prone to leakage, even when a lower viscosity product is comprised in the container, is met by providing the container with a more elastic resiliently squeezable container.
  • US5,213,236 relates to a dispensing package for fluid products such as liquid soaps, shampoos and conditioners, house hold detergents, cleaners, polishes, moisturizing creams, and the like, and includes a container with a self-sealing dispensing valve mounted therein.
  • Suitable zwitterionic surfactants include betaine surfactants.
  • Such betaine surfactants includes alkyl betaines, alkylamidobetaine, amidazoliniumbetaine, sulfobetaine (INCI Sultaines) as well as the phosphobetaine.
  • the most preferred zwitterionic surfactant is cocoamidopropylbetaine.
  • compositions can comprise alkyl polyglucoside ("APG") surfactant, to improve sudsing beyond that of comparative nonionic surfactants such as alkyl ethoxylated surfactants.
  • APG alkyl polyglucoside
  • the alkyl polyglucoside can be present in the surfactant system at a level of from 0.5% to 20%, preferably from 0.75% to 15%, more preferably from 1% to 10%, most preferably from 1% to 5% by weight of the surfactant composition.
  • the container is then topped up to the brim with additional distilled water at 20 °C and the container reweighed, in order to measure the weight of the distilled water contained within the container after topping up to the brim. From this weight of surfactant solution, the overflow volume can be deduced.
  • the overflow volume is the total volume of the distilled water contained in the container after topping up. The time between immersion in the basin and weighing must be less than 2 minutes.
  • the containers are filled to 10% of the container size (recommended fill volume) at 20 °C with Fairy ® original dark green dishwashing product having a viscosity in the range of 1,000 +/-200 mPa.s, measured at a shear rate of 10 s -1 (for example, Belgian market product, 2018), and the containers sealed with caps comprising V21 - 145 slit-valves (supplied by Aptar). Cups are weighed before the containers are placed upside down in the cups, with the container cap positioned a distance from the bottom of the cup. The containers are then placed, with the cups in a constant temperature oven kept at 40 °C. The containers and cups are then removed from the oven after an hour, the container removed from the cup and the cup reweighed, in order to measure the weight of product that has leaked from the container.
  • Fairy ® original dark green dishwashing product having a viscosity in the range of 1,000 +/-200 mPa.s, measured at a shear rate of 10 s -1 (
  • the purpose of the Leakage Resistance Test is to assess the ability of a liquid dispenser to prevent leakage of the liquid from an inverted container during "impact".
  • the impact occurs when the inverted container is dropped, liquid dispenser side down, from a certain height onto a flat surface.
  • the drop is supposed to mimic the resulting transient liquid pressure increases upon impact inside the inverted container.
  • the leakage resistance ability of the liquid dispenser is evaluated through measurement of the drop height till which no volume/weight of the liquid leaks out when dropped. A higher leak-free drop height correlates to better leakage resistance ability for the liquid dispenser.
  • the steps for the method are as follows:
  • the viscosity of the liquid detergent compositions is measured using a DHR-1 rotational rheometer from TA instrument, using a cone-plate geometry of 40 mm diameter, 2.008° angle with truncation gap of 56 ⁇ m. Unless otherwise mentioned, the viscosity is measured at a shear rate of 10 s -1 .
  • the dimensions and values disclosed herein are not to be understood as being strictly limited to the exact numerical values recited. Instead, unless otherwise specified, each such dimension is intended to mean both the recited value and a functionally equivalent range surrounding that value. For example, a dimension disclosed as "40 mm” is intended to mean "about 40 mm.”
