Definitions

  • the present invention relates to a vessel that is capable of separating and enclosing at least two types of contents by an easy-open peelable seal, and that is particularly suitable for a two-component hair colour.
  • a two-component hair colour comprises a first agent containing an oxidation dye and an alkaline substance, and a second agent with aqueous hydrogen peroxide as the main component thereof, and these are usually enclosed in separate sealed vessels. At the time of use, the two agents are removed into a separately prepared mixing vessel and applied to hair after being mixed with a spatula or the like.
  • both agents must be placed in separate vessels, and mixing must be performed once the agents are removed from their vessels, which creates difficulty in handling.
  • the conventional vessel having an easy-open peelable seal, is formed from a film of resin blends that comprise at least two types of polyolefinic polymers selected from among a low-density polyethylene resin, high-viscosity polyethylene resin, polypropylene resin, and other materials with different fusion-starting temperatures
  • oxygen penetrates extremely easily through the vessel leading to drawbacks that the first agent, which comprises an oxidation dye and alkaline substance, is oxidized and discolored while in storage.
  • free ammonia gas dissipating out of the vessel which leads to an inability to maintain the necessary alkali concentration when aqueous ammonia is contained as the alkaline substance.
  • the vessel is made from materials in which a low-density polyethylene sheet, or the like, is laminated through an adhesive onto the outside of a resin blend sheet comprising a polyolefinic polymer, the adhesive is weakened because of penetrating ammonia gas, which leads to undesirable interlaminar peeling.
  • An object of the present invention is to provide a vessel having an easy-open peelable seal, which is not easily affected by oxygen outside the vessel, and for which interlaminar peeling does not occur, even when ammonia gas evolves from the vessel, wherein this vessel is suitable for various products, including a two-component hair colour for which the effects of outside oxygen must be avoided immediately prior to use, and for which two or more components thereof must initially be kept separate and then mixed at the time of use.
  • the inventors discovered that the foregoing object could be achieved by newly providing part of the material that constitutes the vessel with a gas barrier layer for preventing the effects of oxygen from outside the vessel on the vessel contents, and for inhibiting the effects of ammonia gas generated inside the vessel, and thus developed the present invention.
  • the present invention provides a vessel with at least two compartments separated by an easy-open peelable seal, wherein the vessel comprises a gas barrier layer in part of the vessel material that constitutes at least one of the separated compartments, such that the entire surface of that one compartment is covered.
  • Fig. 1 which is a cross-sectional diagram depicting an example of the vessel of the present invention, depicts an embodiment in which two compartments (A, B) are separated by an easy-open peelable seal S. Substance a is sealed in compartment A, and substance b is sealed in compartment B.
  • the laminate material comprising at least an easy-open peelable material layer and a gas barrier layer is formed into a pouch shape, such that the easy-open peelable material layer is located on the inside of the vessel (specifically, the easy-open peelable material layer 1 is disposed over the entire inside surface of the vessel, and the gas barrier layer 2 is disposed over the entire outside surface thereof).
  • the easy-open peelable material layer 1 need not be disposed over the entire inside surfaces of compartment A and compartment B as long as this layer is disposed over at least part of the seal S.
  • the gas barrier layer 2 may be disposed so as to cover only the compartment in which the effects of oxygen from the outside must be avoided, or for which elimination of the effects of internal ammonia gas is desired.
  • the oxygen permeation rate of the laminate material comprising the gas barrier layer 2 may vary somewhat according to adhesion conditions even in the same structure, but 3.0 cc/m 2 ⁇ day ⁇ atm or less is preferable for avoiding degeneration of vessel contents by oxygen, and 1.0 cc/m2 ⁇ day ⁇ atm or less is more preferable.
  • Gas barrier layers 2 that can be preferable for use in the present invention include polyvinyl alcohol film, silicon dioxide vapor-deposited polyvinyl alcohol film, ethylene vinyl alcohol copolymer film, or silicon dioxide vapor-deposited polyethylene terephthalate film.
  • the thickness of the gas barrier layer 2 may be determined as appropriate according to the desired oxygen permeation.
  • the thickness of the silicon dioxide vapor-deposited layer in the silicon dioxide vapor-deposited polyvinyl alcohol film or silicon dioxide vapor-deposited polyethylene terephthalate film may also be determined as appropriate according to the color, desired oxygen permeation rate, and the like of the vapor-deposited layer thereof.
  • a resin mixture comprising at least two types of polyolefinic resins which have different fusion-starting temperatures, as described in claim 1 of Japanese Patent No. 2675075, and in column 6 (line 41) to column 7 (line 40) of the same specification, can be cited as a preferable material used for the easy-open peelable material layer 1.
  • a protective layer 3 for enhancing impact resistance, abrasion resistance, and the like is provided on the gas barrier layer 2 of the laminate material from which the vessel is composed, so as to be furthermore located outside the vessel (Fig. 2).
  • an adhesive layer 4 preferably, a urethanic adhesive layer
  • a nylon film or oriented polypropylene film can be cited as examples of protective layers 3 that can be preferable for use in the present invention.
  • the thickness of the protective layer 3 and the thickness of the adhesive layer 4 may be determined as appropriate according to the desired oxygen permeation rate.
  • the vessel of the present invention can be manufactured by a process in which, for example, the peripheral edges of two sheets of the laminate material in Fig. 2 are tightly sealed and processed into a pouch shape, such that the easy-open peelable material layers both are inwardly faced to each other, the first contents are introduced to the pouch at an amount of about an half in volume of the pouch, the central part of the pouch is sealed so as to be easy-open peelable, the remaining empty space in the pouch is filled with the second contents, and the open top end of the pouch is tightly sealed.
  • these conditions include heating to a temperature approximately 5°C or more above the highest fusion-starting temperature from among the fusion-starting temperatures of all resins contained in the easy-open peelable material. Conditions of 120°C and 4 seconds are also included as conditions for the easy-open peelable seal.
  • the vessel of the present invention as heretofore described can be preferable for use with hair colour.
  • a hair colour with a vessel having two separate compartments is encompassed by the present invention, wherein a publicly known oxidation dye is sealed in one compartment covered with a gas barrier layer, and.a publicly known aqueous hydrogen peroxide agent is sealed in the other compartment.
  • the vessel of the present invention having an easy-open peelable seal can also be preferable for application to a hair bleach (alkaline agent and aqueous hydrogen peroxide agent), dressing (edible high unsaturated fatty acid and water-based seasoning liquid), cooling agent (ammonium nitrate, water), heating agent (calcium oxide, water), or the like, for which the effects of outside oxygen must be avoided immediately prior to use, and for which two or more components thereof must initially be kept separate and then mixed at the time of use.
  • a hair bleach alkaline agent and aqueous hydrogen peroxide agent
  • dressing edible high unsaturated fatty acid and water-based seasoning liquid
  • cooling agent ammonium nitrate, water
  • heating agent calcium oxide, water
  • the oxygen permeability (cc/m 2 ⁇ day ⁇ atm) of each laminate material is shown in Table 1. All of the oxygen permeability values for Comparative Examples 1 to 3 greatly exceeded 3.0 cc/m 2 ⁇ day ⁇ atm.
  • a first agent comprising 5% MEA (monoethanolamine), 20% BOE (benzyloxyethanol) and oxidation dye, and a second agent with 6% aqueous hydrogen peroxide as the main component thereof were used as contents.
  • the vessels of Examples 1 to 3 provided with a gas barrier layer, showed good storage stability, with almost no decline in performance, even after storage for 6 months at 40°C.
  • the oxidation dye was oxidized by the first agent, and became discolored before 6 months of storage at 40°C were finished.
  • This vessel is a vessel suitable for various products, including a two-component hair colour for which the effects of outside oxygen must be avoided immediately prior to use, and for which two or more components thereof must initially be kept separate and then mixed at the time of use.
