BACKGROUND OF THE INVENTION

Field of the Invention

The present invention relates generally to product packaging, particularly to a product packaging method, and more particularly to a method of assemblying a package suitable for protectively enclosing a photosensitive product.

Description of the Prior Art

Various methods for protectively packaging a product are known in the prior art. Pertinent examples may be found in the following documents :

U.S. Patent No. 4,702,383 (Wender) - Discloses a tamper—evident package comprising a jar with a circular opening, a circular cap that is closingly matable with the opening, and an annular connecting member on the cap with diametrically opposed, frangible tabs extending downwardly therefrom and secured to correspondingly opposite sides of the jar, to seal the jar closed and to evidence tampering by breaking or tearing apart whenever the cap is moved relative to the opening.

Jap. Patent Pub. No. 1-113237 (Fuji) - Discloses a film package comprising a plastic cylindrical can with an open end and an end cap removably attached thereto by a disposable sealing tape that extends across the cap and down onto opposite sides of the can, for protectively containing a 35mm film cartridge.

U.K. Published Patent Application No. GB-2,213,135-A (Fuji) - Discloses a film package comprising a plastic container with an open end or side and a removable or hingedly attached cap, for opening and closing the container around a 35mm film cartridge, wherein an information-displaying label may be attached to the container's outer surface, a seal may extend from the container to the cap to indicate whether the package has been opened, and a lub or tab may project from an edge of the cap to facilitate opening.

While product packaging methods such as those indicated above may have sufficed for their intended purposes, there is now an increasing need for a more efficient and reliable method of assemblying a highly useful and protective product package. That need heretofore has not been satisfactorily met.

SUMMARY OF THE INVENTION

Accordingly, a primary object of this invention has been to meet the foregoing need. That and other objects have been achieved by the invention herein claimed.

This invention finds particular utility in a method of assemblying a package for protectively enclosing a product, the package including a substantially cylindrical container having an open end through which the product is insertable into and removable from the container, an end cap matably attachable to and detachable from said end to close and open the container respectively, the cap having a thumb tab projecting therefrom to facilitate opening

the container, and an information-bearing label applied to at least one of said container and cap. The method comprises (1) attaching the cap to the end to close the container, (2) using the tab to place the container and cap in a predetermined position, and (3) applying the label to said at least one of the container and cap when in said position, so that the label is applied in a preselected orientation relative to the tab.

This invention, and its objects and advantages, will become more apparent in the detailed description of the preferred embodiment thereof presented hereinbelow.

DESCRIPTION OF THE PREFERRED EMBODIMENT

Because certain parts of product packaging arrangements, methods of assembling them, and devices for displaying and- dispensing them, are well known,

the following description is directed in particular to those elements and steps forming, cooperating directly with, or relating especially to, this invention. Elements and steps not specifically shown or described herein are selectable from those known in the pertinent art.

Fig. 1 illustrates, via an exploded perspective view, a package P constructed and configured, in accordance with the preferred embodiment of this invention, to protectively enclose a cartridge C_ of photographic roll film F, such as color print film in the popular 35mm size.

Package P comprises a substantially cylindrical, or can-shaped, container 10 having a closed bottom end 12, an exterior sidewall surface 14, and an open top end 16_, through which film cartridge C is insertable and removable. Attachable to and detachable from end 16, to respectively close and open container 10, is a closure in the form of a mating end cap 1£, which fits closely over and around end 16 in a light-tight manner. Container 10 and cap 18 are both made of an opaque plastic material, such as polyethylene, which is readily recyclable. Cap 18 has a substantially round exterior end wall surface 20 and a peripheral exterior sidewall surface 2 depending therefrom as shown in Figs. 2—4. Projecting radially outward from one side of peripheral sidewall surface 22 is a thumb tab 24 to facilitate pushing cap 18 away from end 16, and to serve other important purposes to be discussed hereinbelow.

A first label 2_6_, mainly round in configuration, has a pair of elongate, flexible, and readily

tearable tab portions 28. extending respectively from opposite sides thereof and bent downwardly therefrom as shown in Fig. 1. Label 26 is adhesively secured to the exterior end wall surface 20 of cap 18, while tab portions 28 are wrapped over and secured to respective sides of the exterior sidewall surface 22 of cap 18. With the cap firmly attached to the container top end 16, the tab portions 28 are then tautly secured to corresponding opposite sides of the exterior sidewall surface 14 of container 10 as shown in Fig. 3. Each tab portion 28 is provided with a small slit 3j0_ at approximately the location thereon where the tab portion leaves the cap, as shown in Figs. 2 and 3, to render the tab portion more easily tearable whenever the cap is pushed upwardly to open the container. Fig. 6 illustrates one of the tab portions having been so torn.

A second label 32, basically rectangular in shape, is adhesively secured to the exterior sidewall surface 14 of container 10, over the tearable tab portions 28, thereby further securing the tab portions to the container sidewall. Label 32 comprises substantially coextensive and registered inner and outer sheet—like portions 4 and 3_6_ respectively. Inner portion 34 has first and second ends 34a and 34b respectively, an inner surface 34i facing toward and adhesively secured to sidewall surface 14, and an outer surface 34o facing away from surface 14. Superposed outer portion 36 has corresponding first and second ends 36a and 36b respectively, an inner surface 36i facing toward and separably adhered to inner—portion outer surface 34o, and an outer surface 36o facing away from the inner portion. The inner—portion outer surface 34o and the outer—portion inner and outer surfaces 36i and 36o

all have product information thereon. Such information presented on outer surface 36o is fully visible when the inner and outer portions are registered as shown in Figs. 2 and 3. To render such information on surfaces 34o and 36i viewable, outer portion 36 is at least partially separable from inner portion 34. Thus, starting at its first end 36a, outer portion 36 is readily peelable away from inner portion 34 toward its second end 36b, but is firmly secured to the inner portion at its second end to prevent the outer portion from being removed entirely. Figs. 6 and 7 illustrate the outer portion 36 peeled back from inner portion 34 almost to their registered second ends 34b and 36b. Consistent with the purpose of keeping the outer portion on the container, its inner surface 36i is adapted to be separably re—adhered to surface 34o when superposed thereupon again after being peeled away to view the product information thereon. Preferably, label 32 is formed as two distinct, coextensive, sheet-like elements comprising its inner and outer portions 34 and 36 brought together in registered face-to-face relation as aforesaid and firmly secured at their second ends 34b and 36b. Alternatively, label 32 could be formed as a unitary sheet-like element folded over upon itself at a medial fold line thereon defining the joined second ends 34b and 36b of its coextensive, registered inner and outer portions, as illustrated partially in Fig. 7.

A third label 18., also mainly round, is separably adhered to the top surface of first label 26. With the help of a peripheral pull tab _0_, label 38 is readily peelable away from label 26, as illustrated in Fig. 4, and is re-adherable. to another surface, such as an exterior surface on the user's camera, for

reference in reminding the user of the particular product removed from the container. As depicted in Figs. 4-6, removal of label 38 leaves label 26 remaining on cap 18. The now-exposed top surface of label 26 may provide information relating to the product, such as the status of an exposed film cartridge returned to the container, as well as spaces wherein the user can record his own information.

An especially advantageous feature of all three of labels 26, 32, and 38 is that they are made of recyclable plastic material that is recyclably compatible with the recyclable plastic material, such as polyethylene, of which the container and cap are made. This feature extends as well to the adhesives used on their adhering surfaces, and to the inks used on their information surfaces. With this feature, the entire package (without the product therein) can be recycled as a whole, without first having to remove the labels .

In assembling the package P just described, after film cartridge C has been fully inserted into container 10 through open top end 16 thereof, end cap 18 is first attached to end 16 to close container 10. Using the outwardly projecting thumb tab 24 as an orienting guide, the joined container and cap are then placed in a predetermined angular position relative to their longitudinal axis A.

Next, with the container and cap held in that position, the first label 26 is adhesively secured to the cap exterior end wall surface 20, and its oppositely extending tearable tab portions 28 are then folded downwardly over corresponding opposite

portions of cap exterior sidewall surface 22 and container exterior sidewall surface 14, and are tautly secured thereto, so that label 26 and tab portions 28 are secured in a preselected angular orientation relative to thumb tab 24. In the preferred embodiment illustrated, that orientation is such that at least a principal part of the information borne by label 26 is readily viewable from a direction substantially opposite to the direction in which tab 24 projects outwardly from surface 22, and tab portions 28 are substantially equally spaced peripherally from tab 24, i.e., tab 24 is peripherally midway between tab portions 28. With that orientation, any upward force exerted upon tab 24 to remove cap 18 results in substantially equal upward tearing forces on tab portions 28 at the locations thereon where those portions have been weakened by the small slits 30.

The next step, with the container and cap still held in the aforementioned predetermined position, is to secure the second label 32 to the container exterior sidewall surface 14 over the depending tab portions 28 already secured thereto, and in the aforementioned angular orientation wherein at least a principal part of the information borne by label 32 is viewable from a direction substantially opposite to that in which tab 24 projects.

Assuming such information to be symmetrically displayed on label 32, this orientation would place the vertical centerline of label 32 diametrically opposite tab 24. As previously mentioned, applying label 32 over tab portions 28 further secures them to the container sidewall.

The final step, still with the container and cap in their predetermined position, is to separably adhere the third label 38 to the upward-facing exterior surface of first label 26, again in the aforementioned angular orientation, so that at least a principal part of the information borne by label 38 is viewable from the aforementioned direction opposite that in which tab 24 projects. With label 38 so oriented, according to the preferred embodiment depicted in Fig. 4, pull tab 40 projects radially outward approximately midway peripherally between thumb tab 24 and the closer one of tab portions 28.

With all three of labels 26, 32, and 38 applied in the same preselected angular orientation relative to thumb tab 24, when container 10 and cap 18 are held in the desired predetermined angular position relative to their longitudinal axis A, at least the principal part of the information visible on each label can be viewed from a side of the package which is substantially diametrically opposite thumb tab 24. A particularly useful advantage of this arrangement will become readily apparent in the following description of a cooperating device for displaying and dispensing a plurality of such film packages .

Fig. 8 illustrates, in perspective, a point-of—sale device D constructed and configured to display and dispense a plurality of product—enclosing packages such as the film package P described above with reference to Figs. 1—7.

in its illustrated embodiment, the device D- comprises a plurality of upstanding tubes 5_ , each

having upper and lower open end portions 5_2 and 5_4, respectively, and a substantially cylindrical sidewall 5_6_ with a longitudinal slot 5_8 therein extending between the two end portions. Each tube 50 is configured to slidably receive therein a plurality of film packages P for successive gravity feeding from upper end portion 52 to lower end portion 54. Each package is received through the open end of portion 52 in such orientation that its end cap 18 faces upward, its thumb tab 24 projects radially in a first direction d into slot 58, and at least a principal part of visible information on its label 32 faces outwardly in a second direction d2 generally opposite the first direction dl in which tab 24 projects .

The device D also comprises means .6_0_ for supporting each tube 50 in an orientation wherein the second direction d2 coincides substantially with a display direction . suitable for viewing. As depicted in Fig. 8, such means is provided by a partial enclosure j>2 having opposing sidewalls and 66. a rear wall £8., a short front panel 7_0_ at its upper end, a front brace 72, and a bottom wall 74. Thus, as oriented by enclosure 62, the second direction d2 coincides with the desired display direction dd, which extends forwardly from each tube 50 while the tab-receiving slot 58 is disposed rearwardly therein. Also as oriented by enclosure 62, each tube is tilted so that its upper end portion 52 is slightly rearward of its lower end portion 54.

In the preferred embodiment illustrated, the cylindrical sidewall 56 of each tube is substantially transparent, so that at least the forward-facing portion of the label 32 on each package in the tube

can be viewed therethrough.

As can be seen in Figs. 8 and 11, the slot 58 in each tube is widened, or flared as at 7_6_, at its open end in upper end portion 52 to facilitate receiving the package thumb tabs 24 therein.

Device D further comprises means 78. adjacent to the lower end portion 54 of each tube for supporting the lowermost one of the packages therein in such a way as to render that package accessible for convenient removal. As depicted in Figs. 8 and 9, such means is provided by a substantially U-shaped shelf 8Q. disposed immediately under the open end of each lower end portion 54 and projecting forwardly therefrom. In supporting the lowermost package, shelf 80 of course serves to support all other packages stacked above that one. It will be noted that the front half of each lower end portion 54 is cut away to a height that permits the lowermost package to be readily grasped and removed, after which the next package above that one simply slides downward to take its place.

in the illustrated embodiment, the displaying and dispensing device D comprises a cluster of eight closely arranged tubes, including front and rear rows of four tubes each, disposed in side—by—side relation. It will be seen that the U-shaped shelves 80 under the four tubes in each row are joined together as one integrally formed piece. Also, it will be seen that the rear row of tubes extends to a lower level than the front row. Thus both the lower end portions 54 of the rear tubes and the joined shelves 80 thereunder are sufficiently below their front—row counterparts to render the lowermost packages in the rear- row fully accessible for removal.

While the present invention has been described in detail with particular reference to its preferred embodiment illustrated herein, it should be understood that variations and modifications can be effected within the scope of this invention as defined by the following claims.
