The inner and outer containers are joined at a neck assembly which has an opening communicating with the inner container. The outer container is partially filled with a fluid, semi-fluid or gel material giving the container a soft, resilient “jelly-like” feel.

Description

  • The present invention relates generally to novel product containers, and more particularly to squeezable single or multi-compartment containers for liquid and paste materials. The invention has particular utility in providing containers having a unique squeezable soft touch or hand feel for high value products such as cosmetics, and will be described in connection with such utility, although other utilities are contemplated.
  • BACKGROUND OF THE INVENTION
  • High value products such as cosmetics typically are packaged in small rigid walled or semi-rigid walled containers such as tubes, jars and bottles. Often the containers are made of various plastic resins, which are somewhat lighter in weight and more shatter resistant than glass, which also is used. Manufactures often differentiate their products from those of other manufacturers by employing uniquely shaped containers, colors and sizes to create unique or distinctive product identification. It is thus an object of the present invention to provide unique containers, which can be manufactured from a wide variety of materials including but not limited to: vinyl, plastic, rubber, films, sheet material, etc which can contain a decorative “jelly-like” solution and a product solution in a separate chamber. Another object of the invention is to provide a multi channel or compartment squeezable containers that are simple and economical to manufacture in a variety of colors and shapes. Yet another object of the invention is to provide unique squeezable containers that provide superior impact-resistance and protection of the contents.
  • SUMMARY OF THE INVENTION
  • The present invention provides a “fun to hold, fun to see and fun to use” flexible container which containers a decorative “jelly-like” liquid, which provides an aesthetically pleasing look and a squeezable feel. Within this container is a separate compartment, which holds the product, which can be a liquid, powder or semi liquid product. Often, but not always, the product is a cosmetic such a lip-gloss, eye shadow, blush, mascara, etc. Usually the “jelly-like” liquid is a bright vibrant color to complement or contrast the product color and provides a squeezable feel.
  • More particularly, the present invention provides novel multi-compartment containers comprising of a separate chamber or bag for containing a liquid or paste type product, surrounded at least in part by an outer chamber or bag. The inner and outer chambers or bags are separated and one chamber usually, but not always the outer, contains a “jelly-like” fluid which is provided for color and/or squeeze-ability, but is not usually dispensed. The inner chamber is usually, but not always, used to contain the product. Depending on the design the separate chambers can be formed using a chamber within a chamber or two chambers formed by creating a sealed seam separating the product chamber from the “jelly-like” fluid containing chamber. The two chambers form a container with the “jelly-like” fluid containing chamber preferably sealed into itself and the product chamber sealed to a neck assembly, which is used to dispense the product. The chamber walls are generally formed of a flexible material. The outer chamber is at least partially filled with a fluid, semi-fluid or gel material giving the outer chamber a soft, resilient “jelly-like” look and feel. Completing the container is a closure for closing the opening, which communicates with the inner chamber, which contains the product.
  • The containers of the present invention may be formed in a variety of shapes and sizes and may be used for holding a variety of products including high valued products such as cosmetics, creams lotions and the like. Also, if desired, solid particles having a density approximating that of the liquid, semi-liquid, gel or other “jelly-like” material filling the outer chambers may be included in the filling to provide aesthetic appeal. In another aspect, the invention provides a method of producing the novel containers, which involves sealing the inner and outer containers from each other and sealing the product container to the neck assembly. The outer container is partially filled with a liquid, semi-liquid, gel or other “jelly-like” material and sealed, and the inner container is filled with the desired product and sealed with a closure.

  • DESCRIPTION OF PREFERRED EMBODIMENTS
  • Referring to FIGS. 1 and 2, there is shown a multi-compartment container 10 made in accordance with the present invention. Container 10 includes an inner chamber or bag 12 having a main body, which includes a upper portion 14, a side wall portion 16 and a bottom portion 18. Chamber 12 is primarily bulb-like in shape, and includes a neck portion 20 formed around a rigid neck element 22 having an opening 24 through which product may be dispensed. Inner container 12 is surrounded by an outer container 30 which also is bulb-like in shape, and includes a neck portion 32, a side wall portion 34 and a base portion 36. Outer container 30 preferably has the same general shape as inner container 12, but is larger in size so that when the inner container 12 and outer container 30 are assembled together, a chamber or space 38 is formed between the inner and outer containers 12 and 30, respectively (see FIG. 2). Space or chamber 38 is partially filled with a “jelly-like” fluid such as mineral oil, and the inner and outer containers 12 and 30 are sealed together at neck 20 by a ring 40 that fits snugly over the upper ends of the inner and outer containers and rigid neck element 22. The containers also may be sealed, to the neck assembly, by heat fusing the inner and outer containers to a rigid neck assembly.
  • Inner and outer containers 12 and 30 are formed of a thin resiliently flexible material such as polyvinyl sheet material or another material that is inert both to the material intended to be held in the inner container 12 and to the fluid in the chamber 38. For example, where the material intended to be held in container 12 comprises an oil-based cosmetic, and the fluid in chamber 38 containers comprises a mineral oil, the inner and outer containers may be made of a polyvinyl chloride (PVC) sheet of appropriate thickness. However, the material used to form the inner and outer containers may comprise other plastic or rubber materials.
  • Referring also to FIG. 3, there will now be described the assembly of the multi-chamber container illustrated in FIG. 1. Pre-formed inner container 12 is loaded into outer container 30 and the two are assembled together on a rigid neck element 22 at a station 50. The outer container 30 is then partly filled from the bottom with a mineral oil at a filling station 52, and sealed. The inner container is then filled through the open top end with a product of choice at a filling station 54, and a removable top or cap 56 which may include an applicator such as a brush 60 is affixed to the top end of the assembly at a capping station. Alternatively, the cap 56 may include a dropper, a rod, a brush, a sponge or a blade applicator or the like.
  • Referring now to FIGS. 4-7, there is shown an alternative embodiment soft-walled multi-compartment container made in accordance with the present invention. In this alternative embodiment the multi-compartment container is constructed from a single pre-formed long necked bag 68 in which the inner container 70 is formed by turning a neck portion 72 of the bag 68 which also forms the outer container 74 in on itself. As before, the inner and outer containers 70, 74 are sealed to a rigid neck element 22 and ring 40, and the inner container capped with a cap 56. As in the case of the first embodiment, the outer container 74 may be partially filled with a mineral oil or the like, while the inner container 70 may then be filled with a high value product and sealed with the cap.
  • Referring also to FIG. 8, a method of forming a multi-compartment container of FIGS. 4-7 will now be described. Referring again to FIG. 4, a bulb-shaped bag 68 having an elongate neck 72 is provided at a station 80. The bag 68 is then partially filled with a “jelly-like” fluid at station 82.
  • Referring to FIG. 5, the neck 72 is pushed into itself using a rod 84 at a station 86 whereby to create the inner container 70. FIG. 6 shows the neck 72 pushed into its final position.
  • A rigid neck element 22 is supplied and is inserted into the neck at a station 88 shown in FIG. 6. Thereafter, an outer sealing ring 40 is press fitted over the neck element 22. The container neck also may be sealed, to the neck assembly, by heat fusing each to the other. The inner container 70 is then filled through the top end with a product of choice at station 90 and the filled container is then capped or sealed with an applicator 56 or other form of cap at station 92.
  • Yet another embodiment of the invention is shown in FIGS. 9 and 10. In this latter embodiment, the inner and outer containers 100, 102 are formed by heat fusing two sheets of flexible film along pattern edges 104, 106 to create the outer container and inner container separated by a barrier line. A rigid neck element 22 and sealing ring 40 supplied and sealed to the necks of the inner and out containers, as before. The inner and outer containers may then be filled, as before, and capped 56.
  • The containers of the present invention can be made in a conventional shape such as an elongated tube or bulb. Usually, however, the containers may be made in unconventional shapes such as star or tear drop shapes to catch the eye of a consumer. Also, if desired, the inner and outer container walls may be made of transparent or translucent materials which may be the same or different color materials. If desired, patterns may be printed on the inner and/or outer container walls. In another embodiment of the invention, particles such as glitter or the like may be incorporated into the fluid in the outer container.
  • It is thus seen that the present invention provides highly unusual eye catching product packaging that satisfies the aforesaid and other objects above described. Additionally, the product has a soft “jelly-like” “squishy” hand feel. Moreover, by making the outer wall and filling material transparent, the user can see how much product is remaining. Also, by making the outer container flexible, the consumer can express essentially all of the contents from the inner container.
  • Various changes may be made in the foregoing without departing from the spirit and scope of the invention. For example, the inner compartment closure or cap may comprise a screw top, or a press-fitted or flip cap. Other changes may be made without departing from the spirit and scope of the invention.
