Definitions

  • This disclosure is directed to container opening structures comprising a container wall member, such as a closure, e.g., a lid, to which there is attached at least one flexible closure tearing means accessible from the exterior of the container and a plurality of pressure-rupturable capsules, each of which contains a volatilizable core material, e.g., perfume or other fragrance, located between the container wall or lid and the tearing means.
  • the tearing means is a flexible tape composed of a plurality of parallelly arranged monofilaments. The operation of the tearing means serves to rupture at least some of the capsules during opening of the container.
  • One major object of the present invention is the provision of a container opening structure and method for the preparation thereof which, upon opening of the container, will release a desired fragrance or other volatilizable material capable of functioning in the vapor state to accomplish a desired objective.
  • the present invention enables the fragrance or other encapsulated core material to be stored without undergoing any significant change prior to the desired moment of use, viz the time when the container is to be opened.
  • FIG. 1 of the drawings is a perspective view illustrating one embodiment of a container opening structure utilizing the present invention.
  • FIG. 2 is a top view of the container opening arrangement of FIG. 1 with alternate means to gain access to the tape.
  • FIG. 3 is a series of five sectional views labeled steps I through V, showing a preferred sequential procedure for formation of a container opening structure(s) in accordance with this invention.
  • container 1 has a closure formed from inner flap 2 and outer flap 3.
  • One longitudinal extremity of inner flap 2 constitutes a reseal tuck flap 4, which, after opening of the container, serves to reseal it by insertion into open ing 5 on flap 3, which opening serves to seat the reseal tuck flap.
  • Tuck flap 4 actually becomes the outer flap once the original closure is opened and then resealed.
  • Flap 3 has two glue lines applied thereto, one lid sealing glue line area being shown at 9 and a capsule tape adhering glue line area being shown in 6. Glue is applied to the inner surface of flap 3 along glue line 6 to adhere container tearing means 7, which contains the encapsulated fragrance or other core material to the interior surface of flap 3.
  • the tearing means is located within a region or area of the container wherein the container wall material is preweakened, e.g., by perforations 10, as shown in FIGS. 1, 2 and steps IV and V ofFIG. 3, to aid in the tearing thereof.
  • the container tearing means can be provided with a tab or extension 8 which in effect extends the container tearing means past the lid of the box to provide access from the exterior.
  • the lid sealing glue line 9 adheres the inner surface of flap 3 to the outer surface of flap 2 to achieve the initial container closure.
  • a V-shaped (or other shape) preweakened region can be employed in flap 3 to provide access to the tearing tape from the exterior of the container.
  • the perforated access tab 12 shown in FIGS. 1 and 2 as having a V-shape can be employed to initiate tearing of the container closure.
  • the exterior view one obtains of the preweakened container wall is shown in FIG. 2.
  • the opener To initiate opening the container, the opener merely grips the initiator tab 12 and applies upward pressure which causes the perforated portion of the lid to yield engaging the closure tearing means 7 which opens the container within a region defined by perforations such as one or more perforated lines as shown in FIG. 2. Alternatively, access to the tearing means 7 can be secured by lifting tab 8 in the region between perforated lines 10 and pulling upward.
  • the container tearing means assembly 7 containing encapsulated fragrance or other capsule core material can be produced readily by fixing a plurality of thin strips of nylon reinforced tape T to a substrate S, e.g., of coating grade paper, at regular intervals as shown in step I of FIG. 3. Any conventional binder, glue, adhesive, etc., can be used for this purpose although a pressure sensitive adhesive is preferable.
  • the tape T constitutes the tearing portion of the closure tearing means in accordance with this invention.
  • the tearing means is a flexible pressure-sensitive plastic tape having a plurality of parallelly arranged nylon monofilaments incorporated therein, said monofilaments being strong enough to pressure rupture the capsules and tear the boxbourd or other container material from which the container is made.

  • the capsules need not be incorporated in the tearing means prior to adhesion of the tearing means to the interior surface of container flap 3 as shown in step III of FIG. 3. Instead, the capsules can be added with the glue ofglue line area 6 followed by addition of the tape T.
  • the capsules are basically generally spherically shaped pressure rupturable cells having an internal core of solid, liquid or gaseous material whose vapor state is functional in respect of a physiologically stimulating or invigorating result or a task to be performed.

  • the capsules can contain liquid or solid insect repellents functioning to repel insects in the vapor state.
  • the capsule core material can be a fragrance, perfume, food aroma, inset repellent, insecticide, etc.
  • the capsule layer can be continuous or discontinuous, although the use of continuous capsule layers is preferred.
