This disclosure relates to a bottle having a top portion comprising an opening, a bottom portion, and a shell portion extending between the top portion and the bottom portion. The top portion includes a sealing part which is arranged to releasable cover the opening. The bottom portion includes a recess such that the bottom portion is dimensioned to receive at least a part of a top portion of another similar bottle. A locking arrangement is included such that the top portion comprises a first locking element and the bottom portion comprises a second locking element for locking the bottle and another similar bottle together.

A mixing container and a method for the manufacturing thereof provide a mixing container which offers high pressure-resistance performance while allowing the sealing membrane to be easily broken when the containers are coupled together, by having the sealing membrane formed in an integrated manner with the metallic bottle end and arranging a breaking line on the sealing membrane. Also, the method for manufacturing a mixing container with which the time and effort required for manufacturing the mixing container may be reduced, to allow mass production at a low cost, as the holding body made from a synthetic resin material and the bottle end made from a metallic material are manufactured separately and subsequently seamed together.

A container having a center portion and two side portions each situated at an angle to the center portion and extending in opposite directions such that the a left half of the container is substantially identical to a right half of the container. The container includes recesses and protrusions which enable the container to stack in two orientations generally perpendicular to each other.

Object to be held by a user, comprising: an external structure arranged to be held by the user, a thin-walled closed bottle made of plastic comprising a body defining an internal volume and a collar,
characterized: in that the external structure is a shell in contact with at least part of the body of the bottle, and in that the shell comprises an upper collar forming an open U or C and arranged to elastically interlock on at least part of the collar of the bottle.

A stackable liquid vessel may be able to receive, store, and dispense various liquids or fluids, such as beverages, cooking oil or vinegar, motor oil, and/or other appropriate materials or substances. Each stackable liquid vessel may be able to at least partially couple to at least one other stackable liquid vessel. An arrangement of stackable liquid vessels may utilize perforated slipsheets to reduce material usage when packing, shipping, storing, and/or displaying multiple stackable liquid vessels (e.g., a pallet of stackable vessels).

Containers are disclosed herein that include a reservoir, a handle disposed on the reservoir at an angle defined by a grip axis. The handle is configured for a single grip position and having a midpoint that coincides with a midpoint of a user's grip when the handle is gripped by a user. A first center of gravity coincident with a resting axis is substantially perpendicular to the bottom wall when the bottom wall is placed on a horizontal surface. A second center of gravity coincident with a carrying axis is substantially perpendicular to the grip axis when the container is carried by the handle.

A plastic internally hollow body has a cavity for containing liquids, solids or gases, and includes a main body shaped and having an inner surface at least partially defining the cavity. The inner surface terminates in a shaped edge that delimits a coupling aperture to the cavity. The internally hollow body includes a closure body, having an outer sealing surface suitable at least partially engaging the inner surface of the main body. The closure body at least partially closes the cavity in correspondence of the coupling aperture. The main body is joined to the closure body at least partially along the shaped edge by a joining element over-moulded to the main body and the closure body and covering the over-moulding seat resulting between the main body and the closure body. A method for making the internally hollow body over-moulds the joining element by injection moulding with an over-moulding mould.

The present invention relates to a container unit for engaging with a second container, comprising: a) a container body having a neck portion, wherein said neck portion includes a first sealable opening; and b) a coupling mechanism disposed at said neck portion for enabling engagement with said second container for combining the volume of said container unit and said second container, wherein said coupling mechanism includes: i) a first ring-like seal located at an upper end of said neck and sized to engage an inner wall of an opening of said second container; and ii) a first shoulder, spaced apart from said first seal, sized and configured to sit on an open edge of said second container, wherein said shoulder is in removable abutting relation with the open edge of said second container, while said neck portion is inserted by a maximum extent through the opening of said second container, thereby defining the maximum extent of said first ring-like seal.

A container includes a finish, a shoulder portion, a body, and a base portion. The finish defines an opening. The shoulder portion extends from the finish. The body extends from the shoulder portion and defines a chamber. The base portion extends at an end of the body opposite to the shoulder portion and is moveable from an as-blown position to an expanded position and from the expanded position to a retracted position. The base portion includes a standing ring, a pivot area, and a central area. The pivot area is disposed between the standing ring and the central area. The pivot area is configured to flex and move the central area along the longitudinal axis when the base portion moves from the as-blown position to the expanded position, and from the expanded position to a retracted position.

A system for collecting, storing, and dispensing breastmilk can include stackable containers with various shaped lids and bottles that are shaped complementary to each other to provide stability to the stacked container assembly. In some examples, the lids and bottle also include attachment features that engage with each other to secure a bottle of a top container to the lid of a bottom container.
