The present invention relates to containers for holding liquid samples. The containers may be useful for mixing a liquid sample or lysing cells in a liquid sample. The invention also relates to methods of using the containers of the invention.

The container includes an ink well and a base for the ink well. The ink well has a side defining an open top. It also has a bottom surface. The base includes a base wall configured to receive the well. The base wall has an upper section surrounding and engaging the well side proximate the open top of the well. It also has a lower section extending downwardly from the upper section. The lower base wall section includes at least one set of spaced legs. The spaced legs define a recess adapted to receive a leg of another similarly shaped container in order to interlock the containers in various arrangements.

A fluid dispensing container is provided. The container includes a container body formed from a first flexible material defining an interior cavity. The container includes a membrane formed from a second flexible material and a seal coupling the membrane to the inner surface of the container body. The membrane divides the interior cavity into a contents chamber and a dispensing chamber, and the membrane and the seal are configured to be fluid tight to maintain fluid within the contents chamber prior to rupture of the membrane. The rupture stress of the second flexible material is less than the rupture stress of the first flexible material such that, as fluid pressure within the contents chamber increases, the membrane is configured to rupture without the container body rupturing.

Paint tester and methods of testing paint using the paint tester. The paint tester having a sealed receptacle containing paint, a foam applicator, and a seal cutter. The methods comprising rotating the seal cutter with respect to the receptacle until one or more teeth will cut into and break a seal on the receptacle, applying inward pressure to an exterior surface of a receptacle wall causing paint to flow from the receptacle through a channel exit of the receptacle, through a conduit defined in the seal cutter, out a conduit exit encircled by crenulations, through pores in the applicator, and onto an exterior surface of the applicator, and touching the exterior surface of the applicator to a surface upon which paint is desired.

Water-soluble films made from copolymers of butene-diol and vinyl alcohol, wherein the films have improved barrier properties (such as low transmission rates for oxygen and water vapor) as well as good solubility. The water-soluble films may form at least a portion of a water-soluble unit dose article, a flexible package, and/or a personal care product or products.

The multi-chambered well dosage form and device disclosed herein can be single or multi dose capable for administration of pharmaceuticals of a range of particle sizes. The present dosage devices and systems provide for improved efficiency and patient ease of use owing to its compact size and simple design, low cost, and consistent, contamination free dosing of dry powder medicaments or other agents. The present disclosure provides a multi-chambered dosage form containing dry powder medical composition containing chamber well with an internal piercing device and one or more adjacent gas-filled chamber wells to aid the dispense of the powder contents to the user and in certain embodiments, without the requirement of an external energy sources common with active devices known in the art. Said methods, systems and devices provide increased ejection fraction and hence greater efficiency of drug delivery above that as provided by current devices.

A disposable blister package according to an example of the present disclosure includes a first portion and a second portion. A cavity is formed in the second portion and contains a compound. The first portion is separable from the second portion at a snap line, and the first portion is operable to spread the compound.

Disclosed is a pair of capsules assembled together and respectively including two different phases to be mixed in order to obtain a personalized cosmetic product, including: two pouches respectively containing the two different phases and respectively included in the two capsules and interconnected by a communication channel including at least one portion of narrow cross-section relative to the two pouches, this portion of narrow cross-section of the communication channel including two right-angle bends.

There is provided a pack (10) in the form of a stirrer for a hot or cold beverage. The stirrer comprises first and second films (13, 14) sealingly connected around a periphery to enclose a volume in which is disposed a liquid. The liquid is conveniently disposed in an elongate channel (15) formed in one of the films. Openable portions (17, 55) are provided at respective ends of the stirrer, one openable portion (17) allowing the liquid to flow out once opened and the other openable portion (55) acting as a vent. Each openable portion is opened by peeling apart the two films and has a stronger connection (52, 57) provided to limit the opening of the ends.

The present technology provides a beauty care system for manicure and pedicure products in individual use packaging. This system allows for a fresh set of products be used on each client, improving the efficacy and sanitation of the products being used. Further, the system allows for consumers to mix and match products and better estimate number of manicure and pedicure sessions that can be completed with remaining beauty care products.
