A device is provided that assists with equalizing air pressure within a container with the atmospheric air pressure as liquid is being poured from the container and includes one or more relatively short air tubes. The device is provided with the ability to simultaneously equalize pressure in the container while also providing a drip collection mechanism. The device may be configured for unidirectional pouring or multi-directional pouring.

A flexible, stackable container for storing a quantity of a product may include a sealed package formed from a single sheet of film and retaining the quantity of the product disposed therein, and a lid fitment attached to a first side of the package. The first side of the package may have an outer first surface of the film and outwardly extending first corner seals formed in the film at the edges of the first side and surrounding the first side of the package. The package may also have a second side disposed opposite the first side and outwardly extending second corner seals formed in the film at the edges of the second side and surrounding the second side of the package.

A pouring element for a package having a base body, a polyhedrally formed flange which is designed for joining to a package sleeve and whose joining faces converge in face abutments, as well as a pouring element for a package, in which the package sleeve is correspondingly joined to the pouring element. Provision is made for receiving areas to be formed in the area of the face abutments for the fold line of the package sleeve ears, in order to prevent the package from becoming damaged during the joining process between the pouring element and the package sleeve and during the folding of the package sleeve ears and hence keep it leak-tight.

A pouring element for a package having a base body, a polyhedrally formed flange, the flange inner surfaces of which converge in face abutments, for joining to a package sleeve and at least one holding element projecting on the inside of the flange for operatively connecting to a mandrel of a packaging machine, as well as a pouring element with polyhedrally formed gable surfaces, which are correspondingly joined to the polyhedrally formed flange. Provision is made for the holding element to be formed as a rounding in the area of the face abutments on the inside of the flange, in order to prevent the pouring element from becoming damaged during the whole joining process with the package sleeve when putting the pouring element onto, holding it on and removing it from the mandrel and additionally in order to guarantee a secure and precise hold.

Packaging container comprising a top part (110) comprising a pouring spout for pouring the contents of the container a tubular body part (120) comprising an upper end and a lower end, the upper end being joined together with the top part along a circumferential edge of the upper end of the body part, the body part further comprising a first group of crease lines (132) extending from a lower end of the body part towards its upper end. The top part comprises a recessed portion (117) and the recessed portion and the first group visually form one surface, wherein the one surface near the interface area between the first group of crease lines and the recessed portion of the top part provides gripping support for one or more fingers of a hand, when the packaging container is held by the hand and the remaining fingers during pouring the contents from the packaging container.

A storage box having a fill viewer created when the negative space of the box flaps are combined when the flaps are folded to close the box.

The sealing device 100 of a container 1 is provided with an inner plug 10 and an upper closure 20. The inner plug 10 has a separation part 12 for forming an opening by separation. A first screwing part 51 for attachment of the upper closure 20 is provided between the inner plug 10 and the upper closure 20. The upper closure 20 has an inner cylinder part 20c which is a support part catching a separation part 12 by a second screwing part 52 in opening the plug and separating the separation part 12 from the inner plug 10. The second screwing part 52 is in a reverse thread relation with respect to the first screwing part 51 and has a barb-shape which facilitates pushing the separation part 12 into the inner cylinder part 20c rather than withdrawing the separation part from the inner cylinder part 20c.

There is described a sonotrode for sealing an opening device onto a hole of a packaging material destined to from a sealed package, comprising: a sealing surface adapted to cooperate with packaging material in order to seal the opening device to the packaging material; a cavity bounded by an opening of sealing surface and adapted to receive the opening device and a ring made in an elastomeric material, partially protruding inside the cavity, and adapted to center a first axis of the opening device on a second axis of the sonotrode.

A cap arranged to interact with a spout. The cap comprises a top section, a side wall section attached to the top section and a tamper element attached to the side wall section in a tearing interface. The tearing interface may be provided with a weakening line that is arranged to break when the cap is unscrewed such that the tamper element is separated from the side wall section. The cap further comprises at least one resilient cutting element arranged to the side wall. The at least one resilient cutting element is arranged to cut off a membrane of the spout when the cap is unscrewed. The cap is arranged such that the weakening line is arranged to break before the membrane of the spout is cut off when the cap is being unscrewed from the spout.

An opening device for a package of packaging material having a pour opening comprises a base frame, a collar integrally connected to and extending from the base frame and a closing element configured to cover and/or close the pour opening. The closing element is detachably fixed to an initial contact portion of the collar. The collar comprises a sealing ring having a first inner surface facing the flow channel and an outer surface opposite the first inner surface. The base frame comprises a second inner surface facing the outer surface. The base frame comprises first and second contact surfaces for contacting the packaging material from first and second faces respectively. The initial contact portion is interposed between the first contact surface and the pouring outlet. An annular interface interposed between the base frame and the collar has a thickness larger than a distance between the first and second contact surfaces.
