Embodiments described herein relate to articles and methods for forming liquid surface films on the interior surfaces of containers for holding one or more products comprising one or more Bingham plastic materials. Bingham plastic materials behave as a solid under no or low shear stress, and behave as viscous liquids when an applied shear stress exceeds a yield stress. In some embodiments, a container for containing a product includes an interior surface and a liquid disposed on the interior surface. Before introduction of a product into a container, the liquid may be surrounded by air. The liquid-air interface in contact with the interior surface makes a contact angle, θ.sub.os(a), with respect to the interior surface of the container, of about 0°. After a product has been introduced to the container, the liquid is at least partially covered by the product. The liquid-product interface in contact with the interior surface, makes a contact angle, θ.sub.os(p), with respect to the interior surface, of less about 60°. The subscript “o” denotes the liquid, subscript “s” denotes the interior surface, subscript “a” denotes air, and subscript “p” denotes a product. In some embodiments, the contact angle θ.sub.os(p) can be less than about 50°, less than about 40°, or less than about 30°.

Containers can include main bodies of various shapes and include one or more recessed channels that extends from one side to another of the container to provide greater ease of use and improved access to materials contained there, such as food and other solids, liquids, or combinations thereof.

A collapsible capsule including a first annular body portion having a first annular body portion proximal end, a first annular body portion distal end and a first annular body portion diameter, the first annular body portion proximal end comprises an opening, a second annular body portion having a second annular body portion proximal end, a second annular body portion distal end and a second annular body portion diameter that is smaller than the first annular body portion diameter, the second annular body portion distal end is a closed end, and an intermediate annular body portion extending from the first annular body portion distal end to the second annular body portion proximal end.

A fluid dispensing system is provided. The fluid dispensing system includes a container formed by a first chamber and a second chamber separated by an internal divider. A stopper element extends through each chamber via a first aperture disposed in the internal divider. A second aperture is disposed in a base of the second chamber, wherein the stopper element is used to selectively allow fluid to flow from the first chamber into the second chamber when the stopper element is in a measuring configuration. When the stopper element is in a dispensing configuration, the first aperture between is closed and the second aperture is opened to allow fluid from the second chamber to flow exterior from the container. In this manner, a measured amount of fluid from the container can be dispensed in a single movement without using a secondary measuring receptacle.

A refill package for liquid products, comprising: (a) a rigid outer container comprising an inside face, an opening, and an air intake means; wherein the opening comprises a removable closure and wherein the air intake means comprises a sealable orifice and a sealing mechanism, and (b) a flexible inner body, for containing a liquid product; wherein the flexible inner body is joined to the rigid outer container around the opening.

A liquid saving device having a container, a lid for attaching to the container, the lid having a top side and a bottom side, a finger element attached to the lid, and a closure for covering the top side of the lid. The liquid saving device also having an inner cover for covering the bottom side of the lid.

Pet owners are frustrated with conventional wet pet food packages as it is difficult to remove product from these packages. Traditional metal or plastic containers and flexible pouches are not designed to fully eject product in one step. Rather, the consumer must perform additional steps such as scooping, scraping, tearing, or twisting to entirely remove product. Provided is a collapsible package for wet pet foods. The collapsible package has tapered flexible sidewall, a rigid ring and/or circumferential peripheral flange attached to a top of the sidewall, and a rigid base attached to a bottom of the sidewall. The flexible sidewall is configured to be compressible between an expanded position, at which point product is held in the container, and a collapsed position, at which point product is effectively ejected from the container. A lid can also be attached to the ring and/or circumferential peripheral flange to seal the container.

In some embodiments, a container for containing a product includes an interior surface and a liquid disposed on the interior surface. Before introduction of a product into a container, the liquid may be surrounded by air. The liquid-air interface in contact with the interior surface makes a contact angle, .sub.os(a), with respect to the interior surface of the container, of about 0.

The liquid-product interface in contact with the interior surface, makes a contact angle, .sub.os(p), with respect to the interior surface, of less about 60. The subscript o denotes the liquid, subscript s denotes the interior surface, subscript a denotes air, and subscript p denotes a product. In some embodiments, the contact angle .sub.os(p) can be less than about 50, less than about 40, or less than about 30.

A method and an apparatus (10) for realising a box (9) starting from a cardboard band (7) for packing a plurality of articles (100) with the box (9), wherein the plurality of articles (100) is contained in a reusable crate (1), the first internal wall (4) of which is positioned such as to minimise the volume of the chamber (5) containing the plurality of articles (100). The apparatus comprises: detecting means (11) arranged so as to detect data on the volume occupied by the plurality of articles (100); cutting means (12) for cutting a cardboard band (7) and obtaining a portion of cardboard band (8) in a flat configuration; a control unit which receives the data from the detecting means (11) and which commands the cutting means (12); movement means (13) for moving the bottom wall (2) of the crate (1); positioning means (14) for reciprocally positioning the portion of cardboard band (8) and the crate (1) such that the portion of cardboard band (8) can receive the plurality of articles (100); folding means (15) for folding the portion of cardboard band (8) in a flat configuration so as to form a box (9).
