Definitions

  • This invention relates to safety closures for containers. More particularly, the present invention relates to a safety closure over a container opening having a dispenser with a peelable seal.
  • a safety closure may have a pair of opposable locking lugs projecting inward from a flexible annular skirt.
  • a container for the closure is also provided with a container neck portion having on an exterior surface a pair of opposable outwardly projecting lugs.
  • the closure has an outer cap and an inner cap.
  • the inner cap is threadably engaged to a container neck.
  • the inner cap is not removable from the container cap until a downward pressure is applied to the outer cap while simultaneously t irning the outer cap.
  • the downward pressure engages ratchets within the inner and outer cap to each other and permits turning of the inner cap along with the outer cap.
  • the simultaneous downward pressure and turning motion requires a minimal amount of strength and dexterity that a child will not possess.
  • containers dispensing low viscosity hydrocarbons such as baby oil, sunscreens, bath oils, makeup removers and some cleaning solvents are often packaged with closures that have flip-open tops and dispensing spouts. Due to the low viscosity of the product, it is also necessary to use a seal with the closure. However, a deficiency in this packaging is that if the consumer does not keep the container upright at all times, the low viscosity fluid will eventually leak past the threads of the closure.
  • hydrocarbon products such as baby oil
  • Aspiration of hydrocarbon products can cause serious injury including fatal pneumonia.
  • Other hydrocarbon products are poisonous if ingested. Since closures for containers dispensing these products do not usually have safety features, these packaging materials may pose a danger to children and others unaware of the risk.
  • a traditional safety closure as described above is not designed to be used with closures having pour spouts. Therefore, it is desirable to have a new type of closure that will seal a container tightly during shipping and even after initial use of the product by the consumer regardless of the position of the container during storage.
  • the new closure must also have a dispensing spout and safety features that prevent access to the contents of the container by children and others incapable of understanding the risks inherent in the product. Further, it is desirable to have such a product that is simple and inexpensive to manufacture by using existing closure technology.
  • a container with a safety closure and dispenser includes a safety closure for preventing access by children and other at risk groups as is known in the art, a container with a neck and an opening, and a dispenser affixed to the container neck and sealing the opening.
  • the dispenser is a barrier film with an aperture therein that acts as a pour spout for dispensing the container contents.
  • the barrier film may be of multilayer construction.
  • the aperture has a peelable seal to prevent leakage of the container contents before purchase and use by the consumer.
  • the design of the present invention provides the previously unrealized advantage of providing a container having a safety closure with the added feature of a dispenser for dispensing regulatable quantities of the container contents.
  • the container and safety closure utilized for the present invention are previously known in the art and so provide a cost effective means of producing a new and safer container for dispensing potentially hazardous products such as low viscosity hydrocarbons in a manner accustomed to by consumers, namely by way of a pour spout. All of the above outlined objectives are to be understood as exemplary only and many more objectives of the invention may be gleaned from the disclosure herein. Therefore, no limiting interpretation of the objectives noted is to be understood without further reading of the entire specification, claims, and drawings included herewith. Various other feature of the present invention will become obvious to one skilled in the art upon reading the disclosure set forth herein.

  • the container 12 has a neck 14 with an opening therein. The opening is sealed with a dispenser 20 to prevent leakage of the contents from the container 12 and easy dispensing of the product by the consumer.
  • the dispenser 20 is covered by a safety closure 30, 40 and threadably affixed to the neck 14 of the container.
  • the safety closure 30, 40 has "child resistant" features that discourage access to the contents of the container by children and others unable to recognize the
  • container 12 may generally have an elongated cylindrical shape, but is not limited to such and may be of any shape that best contains the product or has the greatest aesthetic appeal.
  • the container 12 has a shoulder 13 narrowing to a neck 14 that is of sufficient length to accommodate an external thread for threadably affixing a closure 30,40 to the container 12.
  • a neck 14 At the top of the neck 14 is an opening p ermitting access to the contents of the container 12.
  • lug 16 At the base of the neck 14, adjacent the shoulder 13 is at least one lug 16 and possibly two, placed on opposing sides of neck 14. Lug 16 acts as a barrier to removal of closure 30 and 40 and is an integral component of the safety closure system.
  • the container is of unitary construction and may be made of any of numerous materials commonly known in the art depending on specific product and environmental conditions. Some common examples of materials include but are not limited to polyethylene, polypropylene and polyethylene terephthalate.
  • FIGS. 1 and 4 detail one embodiment of the dispenser 20.
  • the dispenser 20 is designed so that it can be retrofitted onto a standard container 12 and a variety of common closures 30, 40. hi this manner, the requirement for a dispensing means for certain compounds such as low viscosity hydrocarbons can be accommodated with dispenser 20 in combination with numerous commonly available containers and safety closures. This provides an economical packaging and dispensing system with safety features.
  • the dispenser 20 includes barrier film 21 and aperture 25, and may also include overlap tab 22.
  • Barrier film 21 is sealed to the lip of the container 12 opening so that even low viscosity fluids can not leak from the container 12 even if the container is not stored in an upright position.
  • Barrier film 21 may be sealed to the container 21 lip by a variety of means known in the art including but not limited to conduction and induction welding.
  • Barrier film 21 may be a laminate. An exemplary description of a laminate embodiment of barrier film 21 is shown in FIG. 9.
  • a first layer 61 is in direct contact and permanently bonded with the rim of container neck 14.
  • the first layer 61 may be composed of the same material as the container is made, for example, polyethylene, polypropylene and polyethylene terephthalate.

  • the first layer 61 may be composed of a weaker layer of bonding material such as ethylene vinyl acetate.
  • the first layer 61 may itself be a multilayer material consisting of a very thin (approximately .0001 inch) and weak fracture layer the same as the container 12 is constructed coextruded with a similar but thicker (approximately .001 inch) and stronger layer. If barrier layer 21 is peelable from container 12, barrier layer 21 may have a tab for grasping such as overlap tab 22. Overlap tab 22 is an extension of barrier layer 21 beyond the lip of neck 14. The grasping tab maybe of different size and shape as needed.
  • a second layer 62 is in direct contact with the top surface of the first layer 61 and sandwiches the first layer 61 between the second layer 62 and the lip of neck 14.
  • the second layer 62 is an adhesive, such as an epoxy.
  • the second layer 62 is preferably about .0001 inch thick. The second layer 62 functions to bond the first layer 61 to the next layer.

  • the third layer 63 is a conductive metal, for example aluminum. It preferably has a thickness of between .0005 and .001 inch. If barrier film 21 is induction welded to the lip of neck 14, the metallic third layer 63 functions to generate heat for the bonding process. Alternatively, or in addition to its role in induction welding, the third layer 63 may function as a barrier layer to gases or solvents that would otherwise permeate a polymer layer.
  • a fourth layer 64 is in direct contact with the top surface of the third layer 63 and sandwiches the third layer 63 between the second layer 62 and fourth layer 64.
  • the fourth layer 64 is another adhesive layer and may be of the same material and thickness as the second layer 62, such as an epoxy of about .0001 inch thick.

  • dispenser 20 has as a means of dispensing container 12 contents an aperture 25 through b arrier film 21.
  • Aperture 25 acts equivalent to a pour spout, providing a narrowed opening through which a more controlled amount of product may be dispensed than is possible with an unrestricted opening.
  • the presence of aperture 25 through barrier film 21 allows a consumer to squeeze or pour out a small amount of product as needed for use. Further, should container 12 tip over, the smaller opening of aperture 25 will prevent a large quantity of a potentially dangerous product from spilling out.
  • the diameter of aperture 25 is chosen according to the particular qualities and uses of the product within container 12. In one embodiment of the present invention, the diameter of aperture 25 is between about .0625 and .125 inch.

  • aperture 25 may also be positioned near the periphery of barrier film 21 should this location provide a better location for the particular product being dispensed.
  • a particular dispensing system may require more than one aperture 25, and such an embodiment would fall within the spirit of the present invention.
  • a second aperture 25 may provide venting that helps dispense container 12 contents more rapidly.
  • aperture 25 Prior to use by the consumer, aperture 25 is sealed with aperture seal 23 as is best illustrated in FIG. 1.
  • Aperture seal 23 is attached to the surface of barrier film 21, is peelable and completely seals aperture 25 preventing any of container 12 contents from leaking during shipping and storage, regardless of the position of container 12.
  • Aperture seal 23 may also be gas impermeable, thus protecting the contents of container 12 from reacting with exterior gases assuring the contents remain as they were when bottled.
  • the consumer removes the outer safety closure and peals aperture seal 23 away from barrier film 21 as is shown in FIG. 4.
  • the seal between barrier film 21 and aperture seal 23 is strong enough to create a barrier between the outside and inside environments, yet weak enough to be peeled with relative ease by the consumer.
  • aperture seal 23 may be fitted with pull tab 24.
  • Pull tab 24 may be a flap that lifts up as illustrated in FIGS. 1 and 4.
  • An alternative embodiment is illustrated in FIGS. 7 and 8.
  • Aperture seal 53 does not have a separate pull tab 24, but rather the seal holding aperture seal 53 to barrier film 51 does not extend to the outer periphery of aperture seal 53.
