Definitions

  • the present invention relates to a seal for a container and, more particularly, to a seal for a container holding a cream, gel, powder liquid or other substance that allows the scent of the substance in the container to permeate the seal while preventing leakage of the substance within the container.
  • Seals have been commonly used on containers for many years, to prevent leakage or contamination of the substance within the container.
  • seals are used to prevent leakage or contamination on containers containing cosmetics, foods, drinks, medicines and other items in the form of creams, gels, powders, liquids and other substances. Seals used for this purpose are typically placed either within the cap on the container or over the opening on the container.
  • prior art seals are essentially hermetic seals that trap the scent of the product within the container, as well as preventing leakage of the product from the container. These prior art hermetic seals may also result in pressure build-up within the container that may cause the container to expand and collapse based on changes in the surrounding environmental conditions. Although venting seals have been developed to address the pressure build-up problem, these venting seals do not provide the ability to smell the scent of the product in a cost effective manner.
  • the consumer closes the cap and returns the container to the shelf in the store.
  • This sampling of the product causes several problems. First, by placing their fingers into the substance and/or coming in contact with the opening where the substance comes out, the sampler may be contaminating the substance and spreading germs/bacteria. Additionally, each time a consumer samples the product and then returns it to the shelf, the volume of the substance within the container decreases. As a result, the consumer that eventually purchases the product is unknowingly purchasing less than a full container of a product that may have been contaminated and/or contain germs/bacteria.
  • the shelf life of the substance within the container may be reduced or altered by the absence of a seal on the container or having been opened and exposed to the surrounding environmental conditions by a sampling consumer prior to sale.
  • the absence of a seal on a container may result in the substance contacting and/or accumulating within the cap on the container, which may cause spillage when the cap is removed and a less appealing presentation to the consumer.
  • the absence of a seal increases the chances that a product may be tampered with or tainted prior to sale to the consumer.
  • one product utilizes a polytetrafluoroethylene (ePTFE) membrane in a section of the liner to allow the scent from the product stored in the container to come through, while preventing leakage of the substance from within the container.
  • ePTFE polytetrafluoroethylene
  • One such induction liner is made by PERFORMANCE SYSTEMATIX INC.
  • a seal for containers that allows the scent from the substance within the container to come through, offering a tamper evident solution, while maintaining product integrity and preventing leakage of the substance within the container.
  • Any such seal should be capable of use with any type of container and any type of substance stored within the container.
  • Such seal should be further capable of being manufactured using conventional seal manufacturing processes and technologies.
  • Such seal should also be capable of being manufactured at a cost comparable to the cost of current conventional seals.
  • the present invention is particularly suited to overcome those problems which remain in the art in a manner not previously known.
  • the present invention is directed towards a seal for containers that allows the scent from the substance within the container to come through, while preventing leakage of the substance within the container and/or physical contact with the underlying substance by the consumer.
  • a one piece, multi-layer induction seal having at least one slit extending from the top surface of the seal through the bottom surface of the seal is provided.
  • the at least one slit will allow a consumer to sniff the scent emitted through the slit(s), while the seal remains secured to the container, thereby providing a tamper evident seal that prevents leakage, as well as, contamination, damage and/or reduced volume caused by consumers sampling the products.

Abstract

La présente invention concerne un joint d'étanchéité de récipients qui permet à l'odeur de la substance contenue dans le récipient de s'échapper tout en empêchant une fuite de la substance de l'intérieur du récipient et/ou un contact physique de la substance par le consommateur. Plus particulièrement, l'invention concerne un joint d'étanchéité comportant au moins une fente s'étendant de la surface supérieure du joint d'étanchéité à la surface inférieure du joint d'étanchéité en les traversant. Selon l'invention, ladite au moins une fente permettra à un consommateur de sentir l'odeur libérée à travers la fente, le joint d'étanchéité demeurant fixé au récipient, en empêchant ainsi toute fuite, de même qu'une contamination, un endommagement et/ou une réduction de volume provoquée par un prélèvement des produits par les consommateurs.
