Definitions
- the invention relates generally to the field of packaging, and in particular to packaging for long rolls of photosensitive web material. More specifically, the invention relates to a light-tight packaging container, which includes features for keeping the container securely closed to ensure light-tightness during shipping and storage.
- photosensitive web material e.g., photographic film used for surveillance, social/portrait, and commercial imaging
- containers ensuring light-tightness from the manufacturer to the film processor.
- the rolls of photographic film are wound onto cores with or without flanges.
- the light-tight containers generally have a film compartment and a closure adapted to fit rather snugly about the film compartment.
- the containers are often fabricated of metal or plastic.
- closure for such film containers must be securely attached to the film compartment to ensure light-tightness during shipping and handling.
- An existing practice for securing the closure to the film compartment is by wrapping some sort of opaque or partially opaque adhesive material, such as tape, around the circumference covering the seam between the closure and film compartment.
- the manufacturer of photographic film product would apply the adhesive material or tape to the seam between the film compartment and the closure in a dark environment to ensure light-tightness of the product in the package during shipping and handling from the factory to the photographer.
- the photographer removes the tape from the seam and disposes of it in the environmental waste stream.
- the adhesive material or tape introduces added labor cost (in the form of additional operators) to the film manufacture process. Operators would then be exposed to the possibility of injuries when cutting the tape in a dark environment suitable for handling photosensitive film.
- the tape introduces an undesirable cost burden to the film manufacturer who applies the tape to the container to protect the photosensitive product.
- the tape is a waste burden to the photographer who removes the tape and ultiumately disposes of it.
- the tape is a cost burden to the photographer who re-tapes the film container before shipment to the processing lab.
- the tape is a waste burden to the processing lab that removes the tape to access the exposed film. Thus, at some point the removed tape is disposed of by the processing lab.
- an object of the invention to provide a light-tight packaging container for photosensitive film product that is easy to access in a dark environment.
- Another object of the invention is to provide a light-tight packaging container that can be easily resealed in a dark environment without the need for additional materials.
- Yet another object of the invention is to provide a light-tight packaging container for photosensitive film that resolves the problem of adding product to the environmental waste stream.
- a first detent feature formed on a flange of the film compartment interlocks with a cooperating second detent feature formed in the closure to secure the film compartment from the penetration of light.
- a light-tight packaging container comprising:
- the present invention has numerous advantageous effects over current developments. First, it eliminates the need for an adhesive tape to secure the seam between the closure and product compartment to ensure a light-tight condition inside the product compartment. Next, it eliminates the cost and waste associated with the adhesive tape. Further, it is simple and cost effective to manufacture. And, the packaging container of the invention is easy to use.
- packaging container 10 and or components thereof suitable for storing and shipping, under light-tight conditions, an article, e.g., a roll of photosensitive film, is illustrated.
- the closed packaging container 10 of the invention is depicted having a container compartment 12 and a closure 22 (described below) fitted snugly about the container compartment 12 in a manner that prevents the penetration of light.
- packaging container 10 has a container compartment 12 having a generally cylindrical shape.
- container compartment 12 has a substantially circular base 14, sidewalls 16 surrounding the base 14 and an opening 17 opposite the base 14 for accessing the container compartment 12.
- the sidewalls 16 have a flange 18 that extends at least partially around the circumference of the container compartment 12.
- the flange 18 includes a first detent feature, preferably a protuberance 20, which extends axially from the flange 18.
- Closure 22 has at least one second detent feature 24, preferably two spaced notches, configured for interlocking with the first detent feature 20 in the flange 18 of container compartment 12.
- Second detent feature 24 is preferably at least one notch formed in a peripheral end edge 26 for capturing the protuberance 20 in the flange 18 thereby securing the closure 22 from movement along the flange 18.
- FIG. 5 an alternative embodiment of the packaging container 10 (Fig. 1) of the invention is illustrated.
- sidewalls 30 surrounding base 14 have a flange 18 and a first thread 36 extending helically at least partially around the sidewalls 16.
- the flange 18 includes a first detent feature 38 extending axially therefrom.
- Closure 40 is configured for closing the opening 17.
- Closure 40 has an inside second thread 42 extending helically about an inner wall 43 of closure 40 for cooperatively engaging the outside first thread 36 of container compartment 12.
- a peripheral edge 44 of the closure 40 includes a second detent feature 46 for engaging the first detent feature 38 in the flange 18 thereby securing the closure 40 from axial movement along the flange 18.
- closure 40 can tightly close upon container compartment 12 by threadably screwing the first thread 36 into the second thread 42 so that the first detent feature 38 aligns with and then interlocks the second detent feature 46. This prevents light penetration into the container compartment 12 and unintended unscrewing of the closure 40 after the closure 40 has been coupled through axial pressure with the container compartment 12.
- Closure 40 may have a plurality of ribs 52 along its periphery for ease of engaging and disengaging the second thread 42 from the first thread 36.
- the first detent feature 38 is preferably a protuberance having a generally arcuate shape.
- the protuberance and the notch may have practically any shape such as a generally square shape, a generally V-shape, or a generally C-shape.
- Fig. 5 Depicted in Fig. 5, on either end of the generally arcuate shape protuberance 38 is a first land 54 and an opposed second land 56.
- the first and second lands 54, 56 guide the protuberance 38 between a light-tight and a light- "loose" position relative to the second detent feature or notch 46 (Fig. 6).
- a method of forming a light-tight packaging container 10 for photosensitive film product includes the step of providing a packaging container 10 and a removable closure 22 configured to fit snugly about the container compartment 12, each as described above.
- a first detent feature 20 is formed in the container compartment 12 by, for instance molding, and a second detent feature 24 configured for interlocking with the first detent feature 20 in a light-tight position is formed in the interior of the closure 22.
- the removable closure 22 is fitted on the container compartment 12 so that the first detent feature 20 interlocks with the second detent feature 24 in a light-tight relations.
- packaging container 10 may include a closure 60 having at least one first thread 62 on an interior wall 64 and at least one detent feature 66, as described above.
- container compartment 68 may include at least one second thread 70 helically wound at least partially about the sidewall 69 for cooperating with the at least one first thread 62 in the closure 60.
- Container compartment 68 further has a second detent feature 72, as described above, for interlocking with the first detent feature 66 in the closure 60 when the packaging container 10 is closed.
- the first and second threads 62, 70 enable the user to tightly screw the closure 60 to the container compartment 68.
- the first and second detent features 66, 72 enable the closure 60 to resist axial movement thereby preventing the penetration of light into the container compartment 68 during handling and shipping.
- Packaging containers 10, including the container compartment 12 and closure 22 are preferably made of a rigid thermoplastic material, such as high density polyethylene. Those skilled in the art, however, will appreciate that other material compositions may be used, such as polystyrene or polypropylene.
