Definitions
- the present invention relates to a device and method for forming packaging, More specifically, the present invention relates to tooling and a method of using the tooling to mold small self-standing packaging containers or sachets from unitary generally rectangular cardboard blanks.
- Small disposable packaging containers or sachets are commonly used to provide consumer samples for assorted products, especially for fluidic products.
- the unitary blanks used to form the sachets are laminated with a moisture proof coating and, when molded, form a completely sealed and sterile environment.
- the sample products include lotions, perfumes, food products and other consumer goods which would benefit from small sealed unitary packaging.
- High quality cosmetics are marketed through the use of sachets emblazoned with trademarks and configured for particular trade dresses.
- Self standing sachets are used in the hotel and restaurant industry to provide consumer products in bathroom facilities, eliminating the need for storage baskets or the like. There is an ongoing need in the art to provide improved tooling for forming sachets in appealing self-standing shapes.
- the present invention involves the use of tooling with curved surfaces and rounded edges to form packages or sachets from unitary generally rectangular cardboard blanks.
- An object of the present invention is to decrease the incidence of damaged packaging due to the sharp edges used on previous tooling.
- Another object of the invention is to increase the number of packaging shapes possible by forming curved surfaces in packaging containers fashioned from the unitary blanks.
- FIG. 1 is a bottom perspective view of the finished molded package or sachet 94 created by the improved tooling of the present invention and illustrates the base configuration 98.
- the sachet base 98 assumes the general configuration of the forming surfaces 12 and 42 integral to mandrels 10 and 40, shown in FIGS. 2A-2F, from which it was molded.
- End triangular segments 74 are shown curving inwardly into the sachet structure from center segment 72 to create recesses 87. There is no exact line of delineation or border between triangular segments 74 and center segment 72, but rather a gradual succession as shown by curved edges 73.
- the curved edges 73 and gradual slope between triangular segments 74 and center segment 72 resist puncturing caused by previous tooling, as no abrupt fold or crease is created.
- the curved edges 73 also allow the sachet 94 to stand erect upon on its center segment 72 while being supported at opposite ends by the bottom of sealed side seams 92 created by the fusing of package sides 86 during the forming process, as shown in FIG. 4.
- FIG. 2A is a front elevation view of the first mandrel of the present invention generally shown as 10.
- the mandrel 10 has a forming surface 12 that is convex in shape and located on its bottom end.
- the forming surface 12 is hemmed by a rounded perimeter edge 17 which defines the general exterior outline of the forming surface 12.
- a center segment 14 is bowed outward and defined by rounded edges 16. Bordering the center segment 14 are two triangular segments 18 that slope upward from the center segment 14 to complete the forming surface 12 of the first mandrel 10.
- the rounded edges 16 created a gradual succession between the center segment 14 and the triangular segments 18.
- the lengthwise sides of the first mandrel 10, as shown in FIG. 1, have flat parallel center sections 20 defined by generally straight longitudinal edges 24 which extend for substantially the length of the first mandrel 10.
- Angled side sections 22 abut flat parallel sections 20 and converge to generally straight longitudinal end edges 26. This convergence of angled side sections 22 is consistent with the shape of the triangular segments 18 located on the forming surface 12 which defines the bottom ends of the angled side sections 22.
- a bore 30 is located on the top end 28 of the first mandrel 10 and is used for mounting the mandrel 10 to a positioning device such as a cylinder shaft, gear box shaft, solenoid shaft, motor shaft and other actuation devices known to persons of ordinary skill in the art
- the complementary or second mandrel is shown in FIG. 2B generally as 40.
- the mandrel 40 has a forming surface 42 that is concave in shape and located on its top end.
- the forming surface 42 is bordered by a rounded perimeter edge 47 which defines the general exterior outline of the forming surface 42.
- a center segment 44 is bowed inward and defined by rounded edges 46. Bordering the center segment 44 are two triangular segments 48 that slope upward from the center segment 44 to complete the forming surface 42 of the second mandrel 40.
- the rounded edges 46 created a gradual succession between the center segment 44 and the triangular segments 48.
- the lengthwise sides of the second mandrel 40 have flat parallel center sections 50 defined by generally straight longitudinal edges 54 which extend for substantially the length of the first mandrel 40, and are similar to generally straight longitudinal edges 24 of the first mandrel 10.
- Angled side sections 52 similarly to angled side sections 22 of the first mandrel 10, abut flat parallel sections 50 and converge to generally straight longitudinal end edges 56. This convergence of angled side sections 22 is consistent with the shape of the triangular segments 48 located on the forming surface 42 which defines the top end of the angled side sections 52.
- a bore 60 is located on the bottom end 58 of the second mandrel 40 and is used for mounting the mandrel to a device such as a cylinder shaft, gear box shaft, solenoid shaft, motor shaft and other actuation devices known to persons of ordinary skill in the art.
- the forming surface 42 of the second mandrel 40 is fashioned to be complementary to the forming surface 12 of the first mandrel 10, as shown in FIGS. 2A-2F.
- both surfaces should substantially adjoin throughout.
- This complementary function allows unitary blanks, when placed between the forming surfaces 12 and 42, to be generally supported throughout on the areas which contact the forming surfaces 12 and 42. By supporting the unitary blanks on both sides the final shape of the sachet is better determined and the occurrence of puncturing is decreased.
- FIG. 2C is a side elevation view of the first mandrel 10 and helps to better illustrate how the angled side sections 22 converge to longitudinal end edges 26.
- Triangular sections 18 generally assume the planar cross section of angled side sections 22 at the forming surface 12 located at the bottom end of the first mandrel 10. Bowed center segment 14 curves to rounded edges 16 which faintly define one side of the triangular sections 18.
- FIG. 2D is a side elevation view of the complementary or second mandrel 40 and, similar to FIG. 2C, shows angled side sections 52 converging to longitudinal end edges 56.

- the center segment 14 is located between triangular segments 18 and bordered by rounded edges 16, Longitudinal end edges 26 are shown at the vertexes of triangular segments 18 as angled side sections 22 converge outwardly from flat parallel center sections 20.
- Figure 2F is a top view of the second mandrel 40.
- the center segment 44 is located between triangular segments 48 and bordered by rounded edges 46.
- the center segment 44 and rounded edges 46 differ slightly from the rounded edges 16 of the first mandrel, as the arc of the center segment 44 and rounded edges 46 extend inwardly to the second mandrel 40 in a concave fashion,
- the degree of curvature for the rounded edges 46 is also less than the degree of curvature for the rounded edges 16.
- Longitudinal end edges 56 are shown at the vertexes of triangular segments 48 as angled side sections 52 converge outwardly from flat parallel center sections 50.
- FIG 3 is a top view of one embodiment of the unitary blanks 70 used to form the packages or sachets.

Abstract
Description
- The present invention relates to a device and method for forming packaging, More specifically, the present invention relates to tooling and a method of using the tooling to mold small self-standing packaging containers or sachets from unitary generally rectangular cardboard blanks.
- Small disposable packaging containers or sachets are commonly used to provide consumer samples for assorted products, especially for fluidic products. The unitary blanks used to form the sachets are laminated with a moisture proof coating and, when molded, form a completely sealed and sterile environment. The sample products include lotions, perfumes, food products and other consumer goods which would benefit from small sealed unitary packaging. High quality cosmetics are marketed through the use of sachets emblazoned with trademarks and configured for particular trade dresses. Self standing sachets are used in the hotel and restaurant industry to provide consumer products in bathroom facilities, eliminating the need for storage baskets or the like. There is an ongoing need in the art to provide improved tooling for forming sachets in appealing self-standing shapes.
- Various apparatus have been developed for the formation of packaging containers from unitary blanks including Belgian Patent No. BE 547 082, which is in accordance with the preambles of claims 1 and 11, and United States Patent No. 5,313,767. The previous apparatus contain sharp comers and edges which might damage unitary blanks during the forming of packaging containers or sachets. These previous apparatus formed sachets that rely on sharp folds and corners for support points and had difficulty forming curved or bowed support surfaces from unitary blanks. The present invention has been fashioned with rounded edges and curved surfaces to better form curved or bowed surfaces from unitary blanks. The curved surfaces of the present invention decrease the chances of puncturing unitary blanks and create more possibilities for the configuration of unitary blanks. The present invention may more easily form curved surfaces and integrate these surfaces with sharply angled surfaces to create containers that were previously very troublesome to form.
- The present invention involves the use of tooling with curved surfaces and rounded edges to form packages or sachets from unitary generally rectangular cardboard blanks. An object of the present invention is to decrease the incidence of damaged packaging due to the sharp edges used on previous tooling. Another object of the invention is to increase the number of packaging shapes possible by forming curved surfaces in packaging containers fashioned from the unitary blanks. These objects are achieved by the apparatus of claims 1 and 11, and by the use of the apparatus according to claim 8.

- FIG. 1 is a bottom perspective view of the finished molded package or
sachet 94 created by the improved tooling of the present invention and illustrates thebase configuration 98. As can be seen by FIG. 1, thesachet base 98 assumes the general configuration of the formingsurfaces mandrels triangular segments 74 are shown curving inwardly into the sachet structure fromcenter segment 72 to createrecesses 87. There is no exact line of delineation or border betweentriangular segments 74 andcenter segment 72, but rather a gradual succession as shown bycurved edges 73. Thecurved edges 73 and gradual slope betweentriangular segments 74 andcenter segment 72 resist puncturing caused by previous tooling, as no abrupt fold or crease is created. Thecurved edges 73 also allow thesachet 94 to stand erect upon on itscenter segment 72 while being supported at opposite ends by the bottom of sealedside seams 92 created by the fusing ofpackage sides 86 during the forming process, as shown in FIG. 4. - FIG. 2A is a front elevation view of the first mandrel of the present invention generally shown as 10. The
mandrel 10 has a formingsurface 12 that is convex in shape and located on its bottom end. The formingsurface 12 is hemmed by arounded perimeter edge 17 which defines the general exterior outline of the formingsurface 12. Acenter segment 14 is bowed outward and defined byrounded edges 16. Bordering thecenter segment 14 are twotriangular segments 18 that slope upward from thecenter segment 14 to complete the formingsurface 12 of thefirst mandrel 10. Therounded edges 16 created a gradual succession between thecenter segment 14 and thetriangular segments 18. - The lengthwise sides of the
first mandrel 10, as shown in FIG. 1, have flatparallel center sections 20 defined by generally straightlongitudinal edges 24 which extend for substantially the length of thefirst mandrel 10.Angled side sections 22 abut flatparallel sections 20 and converge to generally straightlongitudinal end edges 26. This convergence ofangled side sections 22 is consistent with the shape of thetriangular segments 18 located on the formingsurface 12 which defines the bottom ends of theangled side sections 22. Abore 30 is located on thetop end 28 of thefirst mandrel 10 and is used for mounting themandrel 10 to a positioning device such as a cylinder shaft, gear box shaft, solenoid shaft, motor shaft and other actuation devices known to persons of ordinary skill in the art - The complementary or second mandrel is shown in FIG. 2B generally as 40. The
mandrel 40 has a formingsurface 42 that is concave in shape and located on its top end. The formingsurface 42 is bordered by arounded perimeter edge 47 which defines the general exterior outline of the formingsurface 42. Acenter segment 44 is bowed inward and defined byrounded edges 46. Bordering thecenter segment 44 are twotriangular segments 48 that slope upward from thecenter segment 44 to complete the formingsurface 42 of thesecond mandrel 40. As in thefirst mandrel 10 therounded edges 46 created a gradual succession between thecenter segment 44 and thetriangular segments 48. - The lengthwise sides of the
second mandrel 40, as shown in FIG. 2B, have flatparallel center sections 50 defined by generally straightlongitudinal edges 54 which extend for substantially the length of thefirst mandrel 40, and are similar to generally straightlongitudinal edges 24 of thefirst mandrel 10.Angled side sections 52, similarly toangled side sections 22 of thefirst mandrel 10, abut flatparallel sections 50 and converge to generally straight longitudinal end edges 56. This convergence ofangled side sections 22 is consistent with the shape of thetriangular segments 48 located on the formingsurface 42 which defines the top end of theangled side sections 52. A bore 60 is located on thebottom end 58 of thesecond mandrel 40 and is used for mounting the mandrel to a device such as a cylinder shaft, gear box shaft, solenoid shaft, motor shaft and other actuation devices known to persons of ordinary skill in the art. - The forming
surface 42 of thesecond mandrel 40 is fashioned to be complementary to the formingsurface 12 of thefirst mandrel 10, as shown in FIGS. 2A-2F. When formingsurface 12 and formingsurface 42 are brought together, both surfaces should substantially adjoin throughout. This complementary function allows unitary blanks, when placed between the formingsurfaces surfaces - FIG. 2C is a side elevation view of the
first mandrel 10 and helps to better illustrate how theangled side sections 22 converge to longitudinal end edges 26.Triangular sections 18 generally assume the planar cross section ofangled side sections 22 at the formingsurface 12 located at the bottom end of thefirst mandrel 10. Bowedcenter segment 14 curves to roundededges 16 which faintly define one side of thetriangular sections 18. FIG. 2D is a side elevation view of the complementary orsecond mandrel 40 and, similar to FIG. 2C, showsangled side sections 52 converging to longitudinal end edges 56. - Figure 2E is a bottom view of the
first mandrel 10. In this view the horizontal planar features of the formingsurface 12 are better illustrated. Thecenter segment 14 is located betweentriangular segments 18 and bordered byrounded edges 16, Longitudinal end edges 26 are shown at the vertexes oftriangular segments 18 asangled side sections 22 converge outwardly from flatparallel center sections 20. - Figure 2F is a top view of the
second mandrel 40. In this view, similar to Figure 2E, the horizontal planar features of the formingsurface 42 are better illustrated. Thecenter segment 44 is located betweentriangular segments 48 and bordered byrounded edges 46. Thecenter segment 44 and roundededges 46 differ slightly from therounded edges 16 of the first mandrel, as the arc of thecenter segment 44 and roundededges 46 extend inwardly to thesecond mandrel 40 in a concave fashion, The degree of curvature for therounded edges 46 is also less than the degree of curvature for the rounded edges 16. Longitudinal end edges 56 are shown at the vertexes oftriangular segments 48 asangled side sections 52 converge outwardly from flatparallel center sections 50. - Figure 3 is a top view of one embodiment of the
unitary blanks 70 used to form the packages or sachets. The unitary blank 70 may be composed of a relatively rigid sheet of paper coated or otherwise covered with a thermoplastic material. In other embodiments a suitable substantially thermoplastic or metallic unitary blank may also be used. Unitary blank 70 is generally rectangular in form withintegral cap segments 71 located on either end. At the center of the unitary blank 70 is abottom segment 80, defined byparallel creases 82, from which the final molded container will stand upright upon. Thecenter segment 72 is located in thisbottom segment 80. Bordering thecenter segment 72 aretriangular segments 74. There is no exact line of delineation or border betweentriangular segments 74 andcenter segment 72, but rather a gradual succession. When the bottom 80 is fully formed thetriangular segments 74 will slope upward from thecenter segment 72. Finger creases 78 are positioned along lines A and A'. When the formingsurfaces center segment 72 to gradually curve upward totriangular segments 74. Opposingend triangle segments 85 will become upright and. opposing endrectangular segments 88 will become upright and make contact with their oppositerectangular segments 88. - The formation of the container takes place when the two mandrels are brought together and sandwich the unitary blank 70, as shown in FIG. 4, by a package forming and filling machine. Such a machine is disclosed within the following U.S. patent, 5,313,767 entitled "Multiple Package Forming and Filling Machine" issued to Gentile on May 24, 1994 and is incorporated by reference herewithin. When the two opposing
sides 86 of the unitary blank 70 are brought together bymandrels die 96, the two opposingsides 86 will pivot upward aboutparallel creases 82, thetriangular segments 74 will slope upward about finger creases 78 forming recesses, opposingend triangle segments 85 will become generally upright and opposing endrectangular segments 88 will become upright and make contact with their oppositerectangular segments 88. The die 96 will then heat and fold the blank unitary blank 70 along side creases 84 and, after the sachet is filled, close the top of the unitary blank 70 to seal the package in its molded form. - It is to be understood that the invention is not limited to the exact construction illustrated and described above, but that various changes and modifications may be made without departing from the scope of the invention as defined in the following claims.
