Definitions

  • the invention relates to collapsible, disposable liquid containers and accessories, and more specifically to containers used to dispense irrigating liquids to the body.
  • a vessel containing a lukewarm saline solution has been used for rinsing a person's nasal cavities.
  • Such vessels particularly adapted to that function are often called neti pots.
  • the mucosa of the nasal cavity and paranasal sinuses contains secretory elements (mucosal glands and goblet cells) and a dense ciliary layer.
  • the secretory cells can produce a large volume of mucus that is normally actively transported by the cilia from the sinus through the opening between the sinus and the nasal cavity (sinus ostium).
  • the mucus typically carries cellular debris and bacteria from the sinus cavity through the ostium into the nose.
  • Inflammation of the sinus and nasal mucosa can cause hyperemia, lymphatic swelling, stasis in the blood and lymphatic pathways, which can lead to increased secretion of mucus and reduced mucociliary transport.
  • the inflammation may be caused by allergies, noxious agents, nasal polyps, and other factors.
  • Over time there is often a pathologic increase in inflammatory cells, ground substance, and fibers with a permanent disruption of mucociliary transport and lymphatic drainage.
  • An obstruction of the narrow ducts and ostia between the paranasal sinuses and nasal cavity can develop, resulting in a vicious cycle of increased secretions, edema, and ultimately organized connective tissue and mucosal hyperplasia.
  • Bacteria are not cleared from the sinuses and multiply in the fertile inflammatory environment worsening the chronic sinus inflammation (sinusitis). Treatment with antibiotics, corticosteroids in nasal sprays or systemically, and antihistamines may result in resolution of sinusitis.
  • Sterile rinses are often performed to clean and treat other body parts such as eyes, and to flush and treat wounds.
  • Collapsible, disposable prefilled drinking bottles such as Capri Sun brand fruit drinks, available from Kraft Food Group, Inc. of Northfield, Illinois have been commercially available for many years.
  • the principal and secondary objects of the utilitarian aspects of the invention are to provide an improved vessel for performing irrigation of body parts. These and other objects are achieved by a disposable, collapsible, squeeze-dispensing container carrying a preloaded amount of irrigation solution and having a bottom supply tube connected to spout that can eject solution through the spout while the container is in various orientations including a substantially upright orientation.
  • the spout is adapted to form a seal against a user's nostril.
  • a disposable nasal irrigation device comprises: an oblong collapsible container carrying an amount of a liquid irrigation solution in an internal chamber; said container having a proximal closed end and a distal dispensing end; an openable spout structure sealing said dispensing end and including a nozzle having an outlet port; an oblong feed tube having an inlet port proximate said closed end and open to said internal chamber; and, a passageway extending from said inlet port to said outlet port; whereby squeezing said container while said container is in a dispensing-end-upward orientation creates an overpressure of said liquid irrigation solution within said internal chamber causing a flow of said liquid irrigation solution into said inlet, through said passageway, and out of said outlet.
  • said spout structure further comprises said nozzle having an outer surface surrounding said outlet port.
  • said outer surface is shaped and dimensioned to intimately contact and comfortably form a seal against a nostril of a user.
  • said outer surface is outwardly convex.
  • said outer surface is outwardly concave.
  • said device further comprises a band of resiliently compressible material supporting said outer surface.
  • said nozzle is moveable from a closed position in which flow is prevented, and an open position in which flow is permitted.
  • said device further comprises a locking mechanism preventing closure of said nozzle when said nozzle is in said open position.
  • said locking structure comprises a snap ring biased to engage a slot on a surface of said spout when said nozzle is moved into an open position.
  • said spout structure is opened by rotating said nozzle in a first direction; and wherein said locking structure comprises a ratchet mechanism limiting rotation in a direction opposite said first direction.
  • said tube comprises a substantially cylindrical sidewall and wherein said inlet port comprises a bottom orifice and at least one radial hole through said sidewall proximate said bottom orifice, whereby liquid from said chamber can enter said inlet port while said bottom orifice is blocked and said radial orifice is open.
  • said device further comprises a gasket made from a resiliently compressible material surrounding said bottom orifice.
  • said distal dispensing end is located opposite said closed end.
  • said nozzle is removably fastened to said spout along a threaded refill opening.
  • said liquid irrigation solution comprises a pre-filled amount of saline solution.
  • said liquid irrigation solution further comprises a chemical component selected from the group consisting of an antimicrobial agent, a preservative agent, an anti-inflammatory agent, an analgesic agent, and a pharmaceutical agent.
  • said device further comprises a protective cap removeably covering said nozzle.
  • said protective cap is retained by a frangible retaining ring.
  • a method for rinsing the nasal cavity of a user comprises: selecting a collapsible container preloaded with a liquid irrigation solution; inserting a nozzle having an opening to the solution into a nostril of the user; sealing a surface surrounding said opening to the skin surrounding said nostril; and, squeezing the container while keeping the container in an upright orientation; thereby injecting said solution into the nasal cavity of the user.

  • the container 1 includes a pair of
  • Each panel has a pair of opposite lateral side edges 5,6 which, as they extend upwardly, both gently curve inwardly toward a central vertical axis 4 to form a generally stylized, bullet-shaped border which is substantially symmetric with respect to a center plane containing the central vertical axis.
  • Each panel further includes a substantially fiat, horizontal bottom edge 7 and an opposite, top crowning apical edge or simply apex 8.
  • the shape is further selected so that the widest lateral dimension occurs proximate the bottom edge, which facilitates a bottom inwardly convex vaulted panel or diaphragm 13 which at its center is substantially perpendicular to the central vertical axis.
  • the diaphragm pushes the medial part 14 of the bottom edge of each panel outwardly away from the opposing panel to form the base 12 for supporting the container on a hard flat surface, such as a tabletop, in a dispensing-end-upward orientation.
  • the panels are bonded face-to-face along a peripheral hermetic seam 15 to form an inner chamber 16 for holding the irrigation liquid contents 17 until the liquid is dispensed.
  • the container can be sold containing a preloaded amount specialized irrigation liquid such as a sterile saline solution for enhanced convenience to the consumer.
  • the seam separates to seal against a spout structure 20 located at the dispensing, top end of the container at the apex 8.
  • the spout structure can include a substantially eye-shaped flange 27, an axial stem 21 carrying an axial lumen 23 leading to a distal outlet 22 and having outer threads 27 for carrying a removable outlet-sealing screw cap 19.
  • a screw cap is shown, other means known in the art can be used to releasably open and close the spout such as a pop-up spout shown in Figs. 8-9.
  • the stem 21 of the spout structure 20 includes an outlet 22 for dispensing a flow of the liquid therethrough.
  • the outlet can have a diameter D of at least 0.6 centimeter (0.25 inch) in order to accommodate a larger volume of liquid at a slower velocity to more comfortably and effectively deliver the solution to the user.
  • a substantially cylindrical central axial lumen 23 extends from the distal dispensing outlet through the stem of the spout and into an elongated feed tube 24 terminating an inlet 25 located at the proximal end 26 of the tube. The lumen forms a fluid connection from the inner chamber 16 with the outside of the container, and thus the user's nose when in use.
  • the proximal end 26 of the tube can have a spacing S apart from the inner surface of the diaphragm 13 so that an adequate gap is formed allowing liquid from the inner chamber into the inlet.
  • the lumen is in fluid communication between the inner chamber and the outside of the container.
  • the spout structure has a generally eye-shaped outer flange 27 which provides for a more durable hermetic seal to each panel 2,3 along the apex 8 by providing gradual transitions to the panel seam 15. In this way, the outlet can form the only exit path for over-pressurized liquid in the container.
  • the feed tube 24 is shown as an integral extension of the proximal end of the spout structure 20, however, the tube can be a separately manufactured component that is bonded to the spout structure directly or through one or more intermediate structures.
  • the spout structure 20 further includes a nostril-engaging tip 28 having an outer surface 29 shaped and dimensioned to intimately and substantially sealingly close a single nostril of a user. By sealing against only one nostril, the other nostril is left open to allow drainage of the liquid after it has irrigated the nasal passages.
  • the outer surface 29 of the tip can be convex and completely surround the outlet 22 of the lumen 23 thus spacing the outlet radially away from the nostril walls thereby enhancing the flow of liquid during irrigation.
  • the tip can be sized so that when it is pushed lightly against the nostril, the seal is capable of withstanding pressures of the injected liquid without substantial leaking.
  • an alternate embodiment of the spout structure provides a dispensing tip 38 including an outer contact surface 39 formed upon a resiliently cantilevered skirt 31 extending radially outwardly from the central axis 34, and is conveniently made from the same material as the rest of the tip material and so can be made form a unitary piece of injection molded plastic.
  • the skirt is shaped and dimensioned to enhance its mechanical flexibility by having a tapered disk shape which becomes thinner towards its peripheral edge. This allows the skirt to deflect 35 (shown in dotted line) under forceful contact with the nostril, thus allowing for a resilient seal with nostrils having a larger range of sizes.
  • an alternate embodiment of the spout structure provides a dispensing tip 48 including an outer contact surface 49 made from a band 47 of resiliently conforming material such as such as synthetic rubber, or flexible polyurethane.
  • the band material can have a durometer of between about 30A and 70A.
  • the band can be secured to the spout by a tongue and groove structure 45 and/or adhesive or other means known in the art.
  • the resiliently conforming material better allows the tip to seal more comfortably against the skin surrounding the nostril in a wide range of orientations and differently shaped and sized nostrils.
  • an alternate embodiment of the spout structure provides a dispensing tip 58 including an outer contact surface 59 that has a concave shape surrounding the outlet 56.
  • the concave shape can form a more rugged, and comfortable seal against the nostril along a more radially outward zone of contact, thus accommodating a larger range of nostril sizes and avoiding the potentially uncomfortable deep insertion of the distal tip of the nozzle into the nostril.
  • a band 57 of resiliently conforming material such as synthetic rubber such as polysiloxanes, or flexible polyurethane can form the outer contact surface. The band can be secured to the spout by adhesive or other means known in the art.
  • an alternate embodiment of the spout structure provides a threaded opening 61 in the flange portion 62 which can be engaged by a commensurately threaded separate stem potion 63 connected at its proximal end to the feed tube 64 and having a distal nozzle 65.
  • the threaded engagement between the flange and stem can allow for more rapid pre- filling of the container during manufacturing. Further, by disengaging the stem from the flange the container can be refilled and is therefore reusable. In this way, the nozzle is removably fastened to the flange portion by way of the threaded refill opening.
  • Those skilled in the art of liquid containers will appreciate other means for fastening the stem to the flange such as snap fittings and adhesives.
  • an alternate embodiment of the spout structure provides a locking mechanism 70 for preventing closure of the nozzle once it has been opened.
  • the spout includes a flange portion 71 hermetically sealed to the container 72 and a separate stem portion 73 carrying a moveable nozzle portion 74.
  • the nozzle can be moved axially along an axis 69 from a lower, pre-opened, closed position shown in Fig. 8 where the substantially circular outlet port 75 is sealed by a penetrating substantially cylindrical stopper 76, to an upper, open position shown in Fig. 9 where the stopper 76 has been disengaged from the outlet 75, allowing pressurized liquid to flow from the container through the outlet port passageway.
  • the locking mechanism 70 can include a radially inwardly biased snap ring 81 carried within a retaining groove 82 set into an inner surface of the nozzle 74 which retains the axial position of the ring with respect to the nozzle as it slides axially over part of the outer surface of the stem portion 73.
  • the snap ring 81 can snap radially inwardly into a slot 83 set into the outer surface of the stem portion 73.
  • the snap ring engages both the groove and the slot simultaneously, thereby preventing further axial movement of the nozzle with respect to the stem portion, and locking it in place.
  • the locked nozzle in the open position discourages reuse of the container.
  • Figs. 10-11 show an alternate embodiment of the spout structure 100 which provides a locking mechanism 101 for preventing closure of the nozzle once it has been opened.
  • the spout includes a threaded stem 102 supported by a flange 110 which is bonded to the container panels similarly to the embodiment of Figs. 1-2.
  • a threaded nozzle 103 threadingly engages the commensurate threads of the stem so that the nozzle is screwingly mounted to the stem.
  • a removeable cap 107 covers the outer surface of the nozzle portion and is removed before use. The cap can be held in place by a frangible retaining ring 108.
