Abstract
A packaged product unit including a package with an inner cavity having a pocket portion containing a product and communicating with an elongated portion in which a straw is housed. The straw has a proximal end which leads into the pocket portion and a distal end which is closed by a cap portion of the package. An outer wall of the straw is welded perimetrically to the package in a proximal sealing area at the proximal end of the straw to prevent leakage of the product from the pocket portion along an outer surface of the straw.
Claims20
A unit of packaged product,
- comprising a package with an inner cavity formed by a pocket portion, the inner cavity containing a product, the package having an elongated portion, a straw housed in the elongated portion and a cap portion, the straw having a proximal end portion in fluid communication with the inner cavity of the pocket portion and a distal end portion spaced from the proximal end portion and closed by the cap portion, the proximal end portion of the straw having a terminal proximal edge, the straw having an outer wall welded perimetrically to the package in a proximal sealing area at the proximal end portion of the straw to form a sealing ring, the sealing ring extending from the terminal proximal edge of the straw and towards the distal end portion of the straw to prevent leakage of the product from the inner cavity of the pocket portion along an outer surface of the outer wall of the straw.
A method of packaging a product in a unit, comprising the steps of:
- providing a package with an inner cavity formed by a pocket portion, the inner cavity communicating with an elongated portion, and an access opening providing access to the inner cavity;
- providing a straw having a proximal end portion and a distal end portion, the proximal end portion of the straw having a terminal proximal edge;
- inserting the straw into the elongated portion so that the proximal end portion of the straw is disposed adjacent the inner cavity;
- closing the distal end portion of the straw with a cap portion;
- perimetrically welding an outer wall of the straw to the package in a proximal sealing area at the proximal end portion of the straw to form a sealing ring extending from the terminal proximal edge of the straw and towards the distal end portion of the straw to prevent leakage of product from the inner cavity of the pocket portion along an outer surface of the outer wall of the straw;
- filling the inner cavity of the pocket portion with a product through the access opening;
- and
- closing the access opening by welding.
A unit of packaged product, said unit comprising a package, said package comprising a pocket portion defining a hollow inner cavity containing a product therein and having an open end through which the product exits said hollow inner cavity, an elongated portion connected to said pocket portion, a straw housed in said elongated portion and a cap portion, said elongated portion being disposed between said cap portion and said pocket portion, said straw having a proximal end portion disposed adjacent said hollow inner cavity in fluid communication with said open end thereof and a distal end portion spaced from said proximal end portion and closed by said cap portion, said proximal end portion of said straw having a terminal proximal edge extending to and terminating at said open end of said hollow inner cavity, said straw having an outer surface, said package comprising a sealing ring comprising a weld extending peripherally along said outer surface of said straw and interconnecting said proximal end portion thereof to said elongated portion of said package to prevent leakage of the product from said hollow inner cavity along said outer surface of said straw, said sealing ring at one end thereof originating at said terminal proximal edge of said straw and extending towards said distal end portion thereof.
