Definitions
- the present invention relates to a drinking straw for a package filled with a pourable food product.
- the present invention also relates to a package having a package main body filled with a pourable food product and a drinking straw.
- liquid or pourable food products such as fruit juice, UHT (ultra-high-temperature treated) milk, wine, tomato sauce, etc.
- UHT ultra-high-temperature treated milk
- wine tomato sauce
- etc. are sold in packages made of sterilized packaging material.
- a typical example is the parallelepiped-shaped package for pourable food products known as Tetra Brik Aseptic (registered trademark), which is made by sealing and folding a laminated strip packaging material.
- the packaging material has a multilayer structure comprising a carton and/or paper base layer, covered on both sides with layers of heat-seal plastic material, e.g. polyethylene.
- the packaging material also comprises a layer of oxygen-barrier material, e.g. an aluminum foil, which is superimposed on a layer of heat-seal plastic material, and is in turn covered with another layer of heat-seal plastic material forming the inner face of the package eventually contacting the food product.
- packages comprising a package main body formed from the multilayer packaging material and a drinking straw. Those packages are in particular used for the consumption on-the-go.
- the main package body comprises a main opening configured to allow the insertion of the drinking straw into the main package body.
- the package main body also comprises a separation membrane covering the main opening for separating the inner space of the package main body from an outer environment and which is configured to be pierced by the drinking straw so as to allow the introduction of the drinking straw through the main opening and into the package and the subsequent extraction of the pourable food product through the drinking straw.
- Each drinking straw is typically attached to the respective package main body within a closed plastic envelope. Prior to its use a consumer extracts the respective drinking straw from the envelope and introduces the drinking straw into the package by piercing the separation membrane.
- a drawback of these packages is that the drinking straws may be littered independently and voluntarily or involuntarily from the package main body after the complete or partial consumption of the pourable food product.
- the document EP-A-3692866 of the Applicant discloses a solution to such a problem by providing a drinking straw having a main tubular main body and a sleeve fitted on the main tubular main body.
- the drinking straw comprises a tip configured to pierce the separation membrane.
- the tip is formed by both the main tubular main body and the sleeve.
- the sleeve is provided with an abutment portion, which is configured to allow for the insertion of the drinking straw into the package main body, but which guarantees to abut against an inner surface of the package main body during an attempt to remove the drinking straw and thereby to hinder the removal of the drinking straw.
- the abutment portion can be realized as a thickening or by means of a palm-tree like structure.
- a drawback of such described drinking straws is that the production of these find limits when desiring to further accelerate the production of such drinking straws.

- sleeve 17 may have a single wall thickness.
- abutment portion 25 In use, during insertion and/or introduction of drinking straw 3, in particular of at least sleeve 17 and coupling portion 16 into package main body 2 and through the main opening (i.e. movement of drinking straw 3 along direction Dl), the consumer must exert a force sufficient to overcome the resistance due to abutment portion 25 needing to pass through the main opening. In particular, the passing through of sleeve 17 as a whole is facilitated by abutment portion 25 being frustoconically shaped.
- abutment portion 25 abuts against the inner surface of package main body 2.
- abutment portion 25 cannot be directed out of package main body 2 through the main opening.
