Benefits of technology

[0006]In an effort to provide an improved opening device the present invention, according to one aspect thereof, provides a cap arranged to interact with a spout. The cap comprises a top portion, a sidewall portion depending from the top portion and formed in one piece therewith, the sidewall portion comprising an interior threading arranged to interact with exterior threading of the neck during an opening operation and during a closing operation. Further, the cap comprises a tamper evidence removably attached to the sidewall portion, and the sidewall portion further comprises cutting elements having a first end hingedly attached to the sidewall portion and a free end portion arranged to interact with a membrane portion of the spout, wherein the hinged attachment allows for the cutting element to pivot in an axial direction. The cap is characterized in that the free end portion has a blunt tip and a comparatively sharper cutting edge on a lateral side of the free end portion. This design facilitates initial arrangement of the cap onto a neck or spout, and it also provides an adequate operation during use of the device.
[0015]The cap may be made of polypropylene. Since polypropylene is harder than High Density PolyEthylene (HDPE) a cap made of polypropylene may advantageoulsy be used with a spout made of HDPE. An advantage of having the spout made of HDPE is that the shelf life of the liquid food stored in a bottle provided with the spout may be prolonged since the liquid food is less affected by the outside conditions due to the more resistent material in the spout. More particularly, a spout made of HDPE has a lower Oxygen Transmission Rate (OTR) than, for instance, a spout made of Low Density PolyPropylene (LDPP), which has the positive effect that less oxygen will enter the bottle or the package provided with the spout through the spout, which in turn has the effect that the liquid food in the bottle or package may be stored for a longer period of time without being unsafe to consume.
[0016]Another advantage of having a spout made of HDPE is that a more roboust package is achieved having the effect that more packages or bottles provided with spouts made of HDPE can be piled on top of each other.

Problems solved by technology

A regular screw-cap closure may be opened and reclosed without causing any visible leakage, yet breaking the hermetic seal may hamper the quality of the product in a dramatic way.

Embodiment Construction

[0028]To put the present invention into context a packaging container is shown in the perspective view of FIG. 1. This is a type of packaging container which may utilize an cap according to the present invention. It should be noted that an inventive cap, inventive neck, etc may be used in combination with other packaging containers too. Returning to the packaging container of FIG. 1, it is composed of three constructional parts. A sleeve 150 is attached to a shoulder / neck portion 130, and a cap 100 is arranged on the neck. It is a typical example of a Tetra Top® container, which is a well known carton bottle concept from the present applicant. The shoulder / neck portion 130 is moulded in one piece directly onto the sleeve 150, after which a cap 100 is screwed onto the neck. The sleeve 150 is formed from a packaging laminate of standard design, i.e. a paper core with surrounding laminate layers also well known in prior art.
