However, these sachets can be difficult to open, especially for children, as certain force and skill are required to pierce the sachet with the straw
The pressure required to hold the pouch and insert the straw may also force some of the contents out of the pouch
Also, the sachets are not resealable if the entire contents are not consumed in one serving

Embodiment Construction
[0020] Such as figure 1 Illustrated to 3, a preferred fitting according to the invention (generally indicated by numeral 1) comprises a tubular body portion 2 defining a channel 3 (see FIG. 2), which is open at one axial end 4, figure 1 To 3 this is the lower end. Conversely, the opposite, other or upper axial end of said channel 3 is hermetically sealed by the cover element 6 .
[0021] The body part 2 and the cover element 6 are formed together in one piece as a molded article of suitable synthetic material, preferably polypropylene (PP) or polyethylene (PE), including low density polyethylene (LDPE), medium density polyethylene (MDPE) and high-density polyethylene (HDPE). The choice of material depends on the composition of the packaging film to which the accessory is to be bonded in order to form the flexible pouch. A person skilled in the art of packaging will be able to select the fitting material to ensure sufficient adhesion between the fitting and the film. Of not...

Abstract
A plastic fitment with child-safe properties for attachment to a container component of film-like plastic material, includes a tubular body portion defining a through passage having axially spaced ends. A plurality of welding ribs is formed integrally on the outer periphery of the body portion near one axial end of the through passage. Furthermore, a cap member is integrally formed on the body portion near the other axial end, said cap member sealing the through passage at one end. The cap member is attached to the body portion through a weakened portion that is adapted to break when a rotational force is exerted by hand on the cap member. Radially outwardly projecting, wing-like blades are formed on the cap member at diametrically opposite positions thereof so that a person can place his fingers thereon in order to apply the rotational force to the cap member. The dimensions of the cap member relative to those of the body portion are made such that the cap member can be placed on the body portion for repeatedly sealing the through passage after it has been separated from the body portion. The cap member is also permanently attached in one-piece manner to the body portion through a meandering strap. This invention also relates to flexible pouches and beverage packages incorporating said fitment.
Description
technical field [0001] The present invention relates to child-resistant accessories and their use in flexible sachets and beverage packaging. The invention also relates to flexible sachets and beverage packaging incorporating said fittings. Background technique [0002] Fittings of this type are used in flexible pouches for liquid or fluid or pasty products as well as various cleaning materials. The sachets are generally intended for single use applications. Of particular note are sachets for beverages, such as fruit juices and other flavored beverages, which are consumed directly from the sachets. Currently, plastic-wrapped pointed straws are commonly provided on flexible beverage sachets, which are removably attached to the sachet, intended to pierce the sachet at specific locations to reach the contents of the sachet ( As a representative example of such pouches, see US Pat. No. 3,380,646). However, these sachets can be difficult to open, especially for children, beca...
