Abstract

A composite container for storing product in a hermetically-sealed volume includes a fitment that forms one end of the container. The fitment has an outer face, an inner face, a perimeter edge with an attachment surface formed therein, and an aperture between the outer face and the inner face with an aperture mount configured to receive and secure a closure for sealing the aperture of the container. The fitment also includes a sealing surface on the inner face that surrounds the aperture, and a products pouch with a pouch opening that is sealed to the sealing surface. The fitment further includes a can having a first end that is coupled to the attachment surface of the fitment and a substantially-rigid tubular body extending away from the fitment to form an interior volume that surrounds the products pouch.

First claim

What is claimed is:

1. A composite container for storing product in a sealed hermetically sealable volume, the container comprising:
a can having a spirally wound substantially-rigid cylindrically shaped can sidewall defining an interior volume, a top end defining an opening and a bottom end on which the can may rest during use, the top end comprising a bead;
a substantially cup-shaped fitment comprising a substantially disc-shaped portion covering the opening and defining an aperture and having an inner face, an outer face and a perimeter, a skirt extending upwardly from the perimeter of the covering portion and having an attachment surface formed therein, the attachment surface defining a groove for receiving the bead at the top end of the can, an aperture mount extending upwardly from the covering portion and having a central bore that communicates with the aperture, and a protrusion extending downwardly from the inner face and surrounding the aperture, the protrusion having a sealing surface facing away from the aperture;
a products pouch disposed within the interior volume and having an airtight body with a pouch opening, the products pouch being heat sealed directly to the sealing surface with a hermetic seal to form a hermetically sealable inner volume; and
a closure mountable to the aperture mount and configured to seal the aperture, the closure having a dispensing end located outside the hermetically sealable volume and an intake end located inside the hermetically sealable volume.

2. The container of claim 1 , wherein the composite container includes a longitudinal axis and the sealing surface is substantially parallel with the longitudinal axis.

3. The container of claim 1 , wherein the first end of the can outwardly surrounds the attachment surface of the fitment.

4. The container of claim 1 , wherein the pouch opening is further secured to the sealing surface with a clamp ring.

5. The container of claim 1 , wherein the sealing surface forms a non-circular cylinder.

6. The container of claim 1 , wherein a material forming the fitment is selected from the group consisting of a high-density polyethylene (HDPE), a polypropylene (PP), nylon 6 and a acrylonitrile-methyl acrylate copolymer.

7. The container of claim 1 , wherein a material forming the products pouch is selected from the group consisting of a polypropylene film, a acrylonitrile-methyl acrylate copolymer film, a laminate comprising a polyethylene terephthalate (PET) film adhered to a linear low-density polyethylene (LLDPE) film, a laminate comprising a metalized PET film adhered to a high-density polyethylene (HDPE) film, a laminate comprising a PET film adhered to a metallic foil adhered to a LLDPE film, and a laminate comprising a PET film adhered to a metallic foil adhered to a nylon 6 extrudate.

8. The container of claim 1 , wherein the products pouch includes at least one gusset.

9. The container of claim 1 , wherein the can is made from paperboard.

10. The container of claim 1 , further comprising a base coupled to the bottom end of the can and enclosing the interior volume.

11. The container of claim 10 , wherein the base further comprises a plug base that is insertable into the bottom end of the can and having a rabbet fit.

12. The container of claim 10 , wherein a material of the base is selected from the group consisting of a paperboard material and a metallic material.

13. The container of claim 1 , wherein the aperture mount is a threaded neck finish extending outwardly from the outer face.

14. The container of claim 1 , wherein the closure is a pump spray dispenser.

15. The container of claim 1 , wherein the aperture mount is a circumferential surface substantially perpendicular to the center axis.

16. The container of claim 1 , wherein the products pouch is scored proximate the sealing surface to facilitate the separation of the products pouch from the fitment after use.

17. A composite container for storing product in a sealed hermetically sealable volume, the container comprising:
a can having a rigid, cylindrically shaped can sidewall defining an interior volume, a top end defining an opening and a bottom end on which the can may rest during use, the top end comprising a straight cut top edge;
a substantially cup-shaped fitment comprising a substantially disc-shaped portion covering the opening and defining an aperture and having an inner face, an outer face and a perimeter, a skirt extending upwardly from the perimeter of the covering portion and having an attachment surface formed therein, the attachment surface being attached to the straight cut top edge by a friction fit, an aperture mount extending upwardly from the covering portion and having a central bore that communicates with the aperture, and a protrusion extending downwardly from the inner face and surrounding the aperture, the protrusion having a sealing surface facing away from the aperture;
a products pouch disposed within the interior volume and having an airtight body with a pouch opening, the products pouch being heat sealed directly to the sealing surface with a hermetic seal to form a hermetically sealable inner volume; and
a closure mountable to the aperture mount and configured to seal the aperture, the closure having a dispensing end located outside the hermetically sealable volume and an intake end located inside the hermetically sealable volume.

18. The composite container of claim 17 , wherein the container defines a longitudinal axis and the sealing surface is substantially parallel with the longitudinal axis.

19. The container of claim 18 , wherein the sealing surface forms a non-circular cylinder.

20. A composite container for storing product in a sealed hermetically sealable volume, the container comprising:
a can having a rigid, cylindrically shaped can sidewall defining an interior volume, a top end defining an opening and a bottom end on which the can may rest during use, the top end comprising a straight cut top edge;
a substantially cup-shaped fitment comprising a substantially disc-shaped portion covering the opening and defining an aperture and having an inner face, an outer face and a perimeter, a skirt extending upwardly from the perimeter of the covering portion and having an attachment surface formed therein, the attachment surface being attached to the straight cut top edge by adhesive, an aperture mount extending upwardly from the covering portion and having a central bore that communicates with the aperture, and a protrusion extending downwardly from the inner face and surrounding the aperture, the protrusion having a sealing surface facing away from the aperture;
a products pouch disposed within the interior volume and having an airtight body with a pouch opening, the products pouch being heat sealed directly to the sealing surface with a hermetic seal to form a hermetically sealable inner volume; and
a closure mountable to the aperture mount and configured to seal the aperture, the closure having a dispensing end located outside the hermetically sealable volume and an intake end located inside the hermetically sealable volume.
