Definitions

  • the present invention is directed towards a seal for containers that allows the scent or aroma from the substance within the container to come through, while preventing leakage of the substance within the container and physical contact with the underlying substance by the consumer and maintaining the barrier properties necessary to maximize the shelf life of the product.
  • Fig. 4 is a partial perspective view of a seal in accordance with another particular embodiment of the invention sealed to the mouth of a container;
  • the seal 10, 10' is affixed to the mouth 22 of the container 20, but can be peeled off to access the contents of the container 20.
  • the seal 10, 10' is sealed over the mouth 22 of the container 20 and can be peeled off using a fingernail or, in embodiments having a tab 18, by grasping a tab 18 between the thumb and forefinger to facilitate removal of the seal 10, 10' from the mouth 22 of the container 20.
  • the seal 10 is a non-venting seal. More particularly, the intact layer or layers of the seal 10 do not permit a free flow of air or gas from inside the container 20 to the outside of the container 20.
  • the slit(s) may be formed through all of the layers of the seal, but at an angle, such that the slit entry point is offset through the body of the seal from its exit point.
  • a cap 40 is secured to the container 20 over the seal 10, 10'.
  • the cap 40 is a removable continuous thread closure.
  • the seal 10, 10' can be used with any type of container 20 and closure 40, and for any type of substance stored within the container 20.
  • the seal 100, 100' includes at least one slit 1 12 formed in at least one layer thereof.
  • the slit(s) 1 12 are made through fewer than all of the layers of the multi-layer induction seal 100, 100'.
  • the present invention takes a standard one piece, multilayer induction seal 100, 100' and scores a slit or slits in one or more layers, but less than all of the layers, from the top face 1 14 and/or from the bottom face 1 16, to permit scent to permeate from the product in a container (20 of Figs. 1 - 5), through the seal 100, 100', while preventing venting through the seal and/or slit(s).
  • the slit 1 12 is shaped like a wave (i.e., in the present particular embodiment, a sine wave).
  • slit shapes can be used, as desired, including, but not limited to, slits shaped as otherwise described herein and/or slits configured as a line, a circle, an alphanumeric character, a different form of a wave (i.e., cosine; point of inflection; sawtooth; etc) and/or slits of the types described in U. S. Patent Application Serial No. 13/922,994.
  • each seal 100 can be made to have more than one slit 1 12, as shown more particularly in Figs. 5 and 6B, without departing from the scope and spirit of the present invention.
  • each seal 100, 100' includes at least one slit 1 12, but can include two or more slits 1 12.
  • the slit(s) 1 12 could be formed in the bottom layer or layers of the seal 100, 100' and the top layer 1 10 can be left unperforated. Whether scoring of the slits is performed from the top layer 1 10 down or from the bottom layer 140 up may have a direct effect on the scent permeation, leakage and barrier properties of the seal 100, 100'. Consequently, selection of top side scoring or bottom side scoring is made on a case by case basis in order to optimize scent/aroma permeation through a seal 100, 100', leakage prevention and shelf life for a particular product and packaging combination. Additionally, the barrier properties of the seal 100, 100' (currently measured in terms of oxygen transmission rates (OTR) and moisture vapor transmission rates
  • MVTR can be further controlled by adjusting (reducing or increasing) the size, depth and/or number of slits created in the seal 100, 100'.
  • the barrier properties of the unperforated layer(s) are maintained so as to permit permeation (near to hermetic levels) through the unscored layers, while preventing venting through the seal 100, 100'.
  • Web sheet 120 is assembled as a one-piece, multi-layer sheet prior to slitting, die cutting and/or punching the seals 100 from the web sheet.
  • the web sheet 120 is, first, made from a plurality of individual sheets. Subsequently, the slits 1 12 are formed, and finally, the seals 100 are separated from the composite web sheet 120.
  • seals 10, 10', 100, 100' can be made from strips of composite, multi-layered materials, mounted on reels, that are fed through a lining/punching machine to die cut and punch the seal.
  • a sheet 120 including a plurality of multi-layer induction seals 100 (not yet provided with a slit or cut from the sheet 120) is provided to a station 200 including a laser 210.
  • Sheet 120 can be an individual sheet 120 of seals (such as the web sheet 120, above), as shown, or can be part of a roll of seals provided to the station 200. Additionally, although illustrated as having precut seals 100 on the sheet 120, this is not meant to be limiting.
  • the sheet 120 can have the seals precut thereon, or the sheet 120 can be a bulk sheet 120 (not having the seals precut thereon) when provided to the laser 210, such that the slits are ablated into the bulk material and, subsequently, the seals 100 are die cut from the slitted bulk material.
  • the laser 210 can be any type of laser desired, such as, but not limited to, a gas laser (e.g., Galvo laser, a CO 2 laser), a fiber laser, a semiconductor laser, etc. In one particularly preferred embodiment of the invention, the laser 210 has a power of 6.5 Watts or more.
  • the sheet 120 is registered under the laser 210, and the laser 210 is operated to form the slit 1 12 in at least part of each seal 100 using ablation performed by a laser beam 210a.
  • the sheet 120 leaves the laser station 200 with slits 1 12 formed in each seal 100.
  • the seals 100 can then be cut from the sheet 120 to produce individual induction seals 100.
  • more than one laser 210 can be provided at the station 200, to increase speed and/or provide for more paths through the station 200.
  • layers 1 10, 120 and 130 may be cut by the laser, leaving the sealing layer 140, or another scent permeable top layer, intact as a scent permeable layer inhibiting leakage of product through that layer and maintaining the barrier properties of the seal 100.
  • layers 140, 130 and 120 can be cut by the laser, leaving the polyester film layer 1 10, or another scent permeable top layer, intact to inhibit leakage of product and maintain the barrier properties of the seal 100, while permitting the scent of the product to permeate through the seal 100.
  • as few as one layer and as many as three layers can be cut by the laser 210, without departing from the scope and spirit of the present invention.
  • the slits 1 12 can be made at this normal incidence, or can be made at an angle relative to the top plane of the sheet 120 by angling the laser 210 or using a lens system that causes the laser beam 210a to strike the seal 100 at a non-normal angle. Further, the slit 1 12 can be formed in the seal 100 in a single pass of the laser beam 210a, or in two or more passes, as desired.
  • the slit 1 12 can be cut through one or more layers of the multilayer seal 100, by performing five passes of the laser to form the desired slit pattern (sinusoid, in the present example) in the aluminum (back) side of the seal 100, at a depth of .0085 inches through the seal.
  • the slit 1 12 is made by performing from 1 to 8 passes of the laser beam 210a over each seal 100 in the sheet 120.
  • the laser 210 can be stepped in the X axis and Y axis directions, if desired, in order to make the slit in each seal 100.
  • the sheet 120 can be stepped in the X and Y axis directions and the laser may remain stationary.
  • the laser is stepped along the X-axis, only and the sheet 120 is part of a roll that is rolled across the laser station 200 in the direction of the Y-axis.
  • the slits 1 12 can be cut through one or more layers of the multilayer seal 100 (or 100'), by performing two or more passes of the laser to form the desired slit pattern (sinusoid, in the present example) in the aluminum (back) side of the seal 100, at a depth of .0065 inches through the seal.
  • each slit 1 12 can be formed by one ablation pass of the laser 210, or, more preferably in the present embodiment, is formed from multiple ablation passes of the laser 210.
  • a one-piece, multi-layer web sheet 320 (which can be as described in connection with the web sheet 120 of Fig. 7) is fed to a rotary cutting station 310 having a rotary cutter 360 with blades 360a.
  • the blades 360a are used to score the seal 300, while still on the sheet 320, to form the slits 312.
  • the height of the rotary cutter 360 relative to the sheet 320 can be controlled such that the blade 360a cuts through fewer than all layers of the seal 300.
  • the barrier properties of the seal 300 can be maintained such that permeation (including scent permeation) can occur through the unscored layer or layers, but venting and leakage cannot.
  • the seals of the present invention provides a simple, cost effective solution that will allow consumers to sample the scent or aroma of a product while the seal remains secured to the container.
  • manufacturers currently selling products without seals will now be able to include seals on their containers and receive the benefits that seals provide, including maintaining product integrity and barrier properties, extending shelf life and making the seal tamper evident, preventing leakage, preventing products from being
  • the present invention provides a seal for containers that allows the scent or aroma from the substance within the container to come through, while preventing leakage of the substance within the container and maintaining barrier properties to maximize shelf life.
  • a seal can be used with any type of container and with any type of substance or product stored within the container.
  • the present invention may utilize other seal designs, materials and configurations now known or later developed that are capable of being removably secured to a container, preventing leakage of the substance within the container and maintaining barrier properties, without departing from the spirit of the invention. More particularly, it should be appreciated that the seals of the present invention may be embodied in a wide range of structures and designs, and may be suitable for use with many different types of containers.
  • seals 10, 10', 100, 100', 300, 300' of the present inventions are capable of use with many different designs, materials and configurations known in the seal industry and may be manufactured and supplied to container manufacturers as precut discs and/or in rolls consistent with current practices, it can be utilized by closure and container manufacturers and end users using existing lining, sealing and capping equipment and current manufacturing processes and technologies. Additionally, because the seal of the present invention may be manufactured using current, commonly used seal designs, materials and constructions and does not require any specialty equipment or manufacturing processes, it is inexpensive to manufacture and can be readily incorporated into the closure and container manufacturing processes. Further, it can be seen that a seal in accordance with the present invention can be manufactured at a cost comparable the cost of current conventional seals.
