Fitment for a flexible pouch with child-safety properties
View Patent ↗Disclosed is a plastic fitment with child-safe properties for attachment to a container component of film-like plastic material, including a tubular body portion defining a through passage having axially spaced ends, a welding rib, and a cap. Also disclosed are flexible pouch or beverage package comprising the fitment and a process for using the fitment.
1. A child-safe plastic fitment comprising:
(a) a tubular body portion defining a through passage having axially spaced ends, said through passage is open at one of the axial ends;
(b) at least one welding rib integrally formed on said tubular body portion on the outer periphery thereof near the open end of said through passage and outwardly projecting therefrom;
(c) a cap member integrally formed on said tubular body portion near the other end of said through passage and having a base wall and a peripheral wall projecting therefrom, said cap member hermetically seals the adjacent end of said through passage in that said cap member is attached to said tubular body portion through a circumferentially extending weakened portion adapted to break when a rotational force is exerted by hand on said cap member, and the dimensions of said cap member are adapted to those of said body portion such that said cap member can be placed onto said tubular body portion for repeatedly sealing said through passage after it has been separated from said tubular body portion; and
(d) radially outwardly projecting, wing-like blades on said cap member at diametrically opposite positions dimensioned so that a person can place his fingers thereon to gain additional mechanical leverage when a rotational force to said cap member wherein said blades comprise a plurality of lobes dimensioned to prevent lodging of the cap in a child's wind pipes and a plurality of openings therein, or a combination of lobes and openings to provide breathing passages.
2. A child-safe plastic fitment in accordance with claim 1 wherein said cap member is permanently connected in one-piece manner to said tubular body portion through a strap extending there between.
3. A child-safe plastic fitment in accordance with claim 2 , wherein said strap extends externally of said tabular body portion between a connecting portion on said cap member and a connecting portion axially spaced therefrom on said tubular body portion.
4. A child-safe plastic fitment in accordance with claim 3 , wherein an extended length of said strap is substantially greater than the axial spacing of the connecting portions of said strap.
5. A child-safe plastic fitment in accordance with claim 4 , wherein said strap has a substantially meandering form between the connecting portions.
6. A child-safe plastic fitment in accordance with claim 1 , wherein said peripheral wall of said cap member has an internal dimension matched to the external dimension of said tubular body portion so as to close said through passage when said cap member is placed over said tubular body portion.
7. A process comprising attaching a child-safe plastic fitment to a flexible pouch or beverage package wherein the child-safe plastic fitment is as recited in claim 1 , 2 , 3 , 4 , 5 , or 6 .
8. A flexible pouch or beverage package comprising the child-safe plastic fitment of claim 1 , 2 , 3 , 4 , 5 , or 6 .
9. A beverage package comprising: (a) a flexible pouch; (b) a child-safe plastic fitment of claim 1 , 2 , 3 , 4 , 5 , or 6 , and (c) a beverage.
