A sippy cup stacking system comprising multiple substantially identical sippy cups having sippy spout lids that can be mated with the bottom of a first cup while attached to the top of a second cup. Each cup includes a bottom with an annular recess containing a central locking plug capable of mating with a central locking stem protruding from a lid on another cup. The sippy spout on each lid is radially offset from the locking stem and fits into and can move circumferentially in the annular recess on the bottom of the cup to which it is being mated, until the spout is fully enclosed by the bottom of the mated cup.

The invention concerns a container (40), preferably a bottle, presenting a longitudinal axis comprisinga neck portion (42),a shoulder portion (44) connected to the neck portion (42),a bod portion (45) comprising a label portion (46) and a grip portion (48) and connected to the shoulder portion (44) via a first connecting portion (49a), the label portion (46) and the grip portion (48) being connected together via a second connection portion (49b), anda base portion (50) forming the bottom of the container (40) connected to the bod portion via a third connecting portion (49c), wherein the grip portion (48) comprises at least one undulating bead (54).

A food jar is described that may be used to store and transport food items. The food jar includes a container, a lid, and a vent. As the lid is unscrewed from the container, the vent opens to equilibrate air pressure within the container with the atmosphere. The vent relieves high and low pressure within the container. The food jar may also include stopper with a vent. The stopper may include an upper and a lower stopper that form the vent.

A food jar is described that may be used to store and transport food items. The food jar includes a container. The container defines an interior to store a food product. A stopper is sized to close an opening of the container. A base removably engages to a lower portion of the container.

The side wall, extending below a shoulder of the thermoplastic bottle, has a gripping portion formed substantially in the middle of the bottle body and includes a first line and a second line each defined in a vertical symmetry plane. The second line has a second point at minimal distance ds2 between the side wall and the central axis, while the first line has a first point at minimal distance dsl between the first line and the central axis. For these particular points in the gripping portion: .Math.ds2<ds1.Math.hs1<hs2 A thick portion is provided at and above the second point.

A container assembly for holding a beverage includes a walled container having an interior surface and an exterior surface. An expandable grip accessory is operatively coupled to the walled container and includes a grip accessory body movable between an extended configuration and a collapsed configuration. The grip accessory body includes a first end and a second end. A hub is operatively coupled to the walled container and includes an opening sized to receive at least a portion of the second end of the grip accessory body. The first end of the grip accessory body is spaced away from the exterior surface of the walled container when the grip accessory body is in the extended configuration.
