Definitions
- This technology includes bottles that have fitments installed in the bottle necks.
- Plastic bottles can be formed from plastic film.
- One or more webs of the plastic film are unrolled from spools, and are folded and seamed together to form structures known as a preforms.
- Each preform corresponds to an individual bottle, and has a generally flat shape defined by the flat panels of plastic film.
- a fitment may be installed in the neck of the preform to provide a spout.
- the preform is then placed inside a blow-molding cavity that has the size and shape of the bottle, and is expanded under fluid pressure inside the cavity. This deflects the plastic film into the shape of the bottle.
- a cylindrical fitment has an axis and a registration feature.
- the fitment is sealed within a bottle neck in a position in which the registration feature has a predetermined orientation to the bottle neck rotationally about the axis.
- the fitment has a screw thread defining a limit of rotation for a bottle cap to be screwed onto the fitment.
- the registration feature has a predetermined orientation to the screw thread rotationally about the axis.
- the limit of rotation also has a predetermined orientation to the bottle neck rotationally about the axis.
- a cylindrical fitment is mounted on an insertion tool in a position in which a registration feature on the fitment has a predetermined orientation to the insertion tool rotationally about an axis of the insertion tool.
- the insertion tool is moved to a position in which the mounted fitment is located within a bottle neck, and in which the insertion tool has a predetermined orientation to the bottle neck rotationally about the axis. This establishes a predetermined orientation of the fitment relative to the bottle neck rotationally about the axis.
- the fitment can then be secured to the bottle neck in the established orientation.
- the bottle neck is preferably defined by a plastic bottle preform web structure.
- the secured fitment and the web structure are placed into a blow-molding cavity in a position in which the registration feature on the fitment has a predetermined orientation rotationally relative to a registration feature of the mold cavity. This establishes a predetermined rotational orientation between the web structure and the mold cavity.
- the web structure can then be blow-molded into a bottle having a predetermined rotational orientation with the fitment.

- a fitment 20 projects upward from a neck portion 22 of the bottle 10 .
- the fitment 20 is configured and arranged to receive a bottle cap 28 in a specified position relative to the neck 22 and other parts of the bottle 10 .
- a non-cylindrical portion 30 of the cap 28 has a predetermined orientation relative to the front face 12 of the bottle 10 .
- this example of a fitment 20 is a cylindrical tube with a central axis 31 .
- a lower section 32 of the fitment has ribs 34 for gripping to the bottle neck 22 .
- An intermediate section 36 of the fitment 20 has a registration feature.
- the registration feature is a flat 38 that extends lengthwise as chord relative to the circular peripheral shape of the fitment 20 .
- An upper section 40 of the fitment 20 has a screw thread 42 .
- the screw thread 42 on the upper section 40 of the fitment 20 is configured for the cap 28 to be screwed onto the fitment 20 , and defines a limit of rotation of the cap 28 about the axis 31 relative to the fitment 20 .
- the flat 38 on the fitment 20 has a predetermined orientation circumferentially about the axis 31 relative to the limit of rotation defined by the screw thread 42 . This ensures that the cap 28 will have a correspondingly predetermined orientation relative to the fitment 20 rotationally about the axis 31 when the cap 28 is screwed fully onto the fitment 20 .
- the cap 28 has a short cylindrical body 50 with a central axis 51 .
- a top wall 52 of the body 50 has a spout 54 .
- An insert 56 is fitted closely into the body 50 from beneath, and has a screw thread 58 for engaging the screw thread 42 on the fitment 20 .
- the non-cylindrical portion 30 of the cap 28 is a feature that renders it asymmetrical circumferentially about the axis 51 .
- the non-cylindrical portion 30 of the cap 28 is a rectangular flip-top extending diametrically across the top wall 52 .
- a hinge 60 enables the flip-top 30 to move pivotally back and forth between the closed and open positions of FIGS. 5 and 6 .
- the flip-top 30 in this example extends longitudinally in a direction perpendicular to the lengthwise direction of the flat 38 when the cap 28 is screwed fully onto the fitment 20 .
- the bottle 10 in the illustrated embodiment is formed from a plastic film web structure.
- FIG. 8 shows an example of a web structure 100 that can be used to manufacture the bottle 10 .
- the web structure 100 is shown to include four panels of plastic film. These include a front panel 102 , a rear panel 104 , and two gusseted side panels 106 .
- the web panels 102 - 106 are arranged together along the length of the web structure 100 to form multiple bottles 10 having the front, rear and side faces 12 , 14 and 16 shown in FIG. 1 .
- FIGS. 9-12 show a method and apparatus for assembling parts of the bottle 10 .
- the web panels 102 , 104 , and 106 are fed lengthwise between a pair of rollers 120 to form the web structure 100 downstream of the rollers 120 .
- a fitment insertion tool 122 includes a mandrel 124 with an axis 125 , and further includes a driver 126 that is operative to advance and retract the mandrel 124 axially into and out of the web structure 100 .
- the mandrel 124 When the mandrel 124 is being advanced toward the position shown in FIG. 9 , it carries a fitment 20 toward and between the panels 102 - 106 to place the fitment 20 within the web structure 100 . The mandrel 124 is then retracted. In the next step, a pair of grippers 130 ( FIG. 10 ) move into engagement with the fitment 20 . The grippers 130 form a heat seal that fixes the fitment 20 to the web structure 100 , and also pull the fitment 20 and the web structure 100 downward from the position of FIG. 9 to the position of FIG. 10 to advance another section of the web structure 100 downward between the rollers 120 . A seaming press 140 then acts upon the web structure 100 to form seams that attach the panels 102 - 106 together, as shown in FIG. 11 .
- the seaming press 140 forms seams 142 at the bottom of the leading section 144 of the web structure 100 , and forms seams 146 at the top and sides of a trailing section 148 of the web structure 100 .
- This forms the neck 22 in which the fitment 20 is to be inserted.
- the seaming press 140 also cuts out extraneous portions 150 of the web structure 100 , and severs the leading section 144 from the trailing section 148 at a cut line 151 .
- the leading section 144 is thus assembled as a bottle preform 152 with a neck 22 , and the process repeats to form multiple bottle preforms 152 successively in this manner.
- a track 160 feeds the fitments 20 to the mandrel 124 .
- the track 160 is inclined so that fitments 20 loaded at the upper end of the track 160 will slide toward the lower end under the force of gravity.
- a spacer bar 168 is moved across the track 160 to interrupt movement of the fitments 20 .
- the mandrel 124 is then moved downward into engagement with the fitment 20 in the gate 166 , and sections 170 of the gate 166 are opened to allow the mandrel 124 to move the engaged fitment 20 downward into the web structure 100 as described above.
- the spacer bar 168 is then retracted to allow the next successive fitment 20 into the gate 166 .
- the track 160 in this example has a pair of side walls 182 that are spaced apart a distance that is just slightly greater than the diameter of a fitment 20 at the lower section 32 of the fitment 20 .
- a rail 184 projects transversely inward from one side wall 182 at the height of the flat 38 on a fitment 20 .
- the track 160 thus configured to receive a row of the fitments 20 , with the flats 38 on the fitments 20 adjoining an inner edge of the rail 184 . This permits a fitment 20 to be mounted on the track 160 in only one orientation rotationally about the axis 31 of the fitment 20 .
- the track 160 delivers the fitment 20 to the mandrel 124 in the same orientation rotationally about the axis 125 of the mandrel 124 .
- the orientation of the fitment 20 on the mandrel 124 has a predetermined relationship to the web structure 100 . In the illustrated embodiment, this is accomplished by advancing the fitments 20 along the track 160 toward the mandrel 124 in a direction parallel to the axes 189 of the rollers 120 that guide the panels 102 - 106 together into the configuration of the web structure 100 .
- the mandrel 124 moves the fitment 20 into the web structure 100 along the axis 125 , it does not rotate the fitment 20 about the axis 125 , but instead maintains the fitment 20 fixed relative to the rollers 120 and the web structure 100 rotationally about the axis 125 .
- the mandrel 124 thus inserts each fitment 20 into the web structure 100 in an orientation in which the flat 38 extends lengthwise in a direction parallel to the front and rear panels 102 and 104 .
- the fitment 20 is then heat-sealed to the neck portion 22 of the bottle preform 152 in the same orientation rotationally relative to the web structure 100 .
- This provides a correspondingly predetermined orientation between the panels 102 , 104 and 106 of the preform 152 , the flat 38 on the fitment 20 , and the rotational limit of the bottle cap 28 on the fitment 20 .
- that predetermined orientation ensures that the flip-top portion 30 of the cap 28 will extend lengthwise in a direction perpendicular to the front and rear faces 12 and 14 of the finished bottle 10 , with the hinge 60 at the rear, when the cap 28 is screwed fully onto the fitment 20 as shown in FIG. 1 .
- a fitment 20 has a single flat 38
- multiple flats 38 or other registration features could provide multiple corresponding orientations between the panels 102 , 104 and 106 of the preform 152 , the registration feature on the fitment 20 , and the rotational limit of the bottle cap 28 on the fitment 20 .
- a pair of flats 38 at diametrically opposite locations on the fitment 20 would provide a pair of orientations that are offset from each other by 180 degrees.
- a pair of mold structures 190 and 192 are configured to receive the preform 152 for blow-molding of the preform 152 into a finished bottle 10 .
- the mold structures 190 and 192 When the mold structures 190 and 192 are closed, they define a mold cavity in which the front, rear, and side panels 102 , 104 and 106 of the preform 150 are expanded to the size and shape of the front, rear, and side faces 12 , 14 and 16 of the bottle 10 .
- Neck portions 196 of the mold structures 190 and 192 together correspond to the neck portion 22 of the bottle 10 .
- One of the neck portions 196 has a registration feature in the form of a rail 198 projecting radially inward.
- the rail 198 on the mold structure 190 is configured to register with the flat 38 on the fitment 20 in the preform 152 . This helps to ensure that the panels 102 , 104 and 106 of the preform 152 will be expanded into a bottle 10 in which the fitment 20 , and a bottle cap 28 screwed onto the fitment 20 , will have the predetermined rotational orientations described above.

Abstract
A fitment has an axis and a registration feature. The fitment is sealed within a bottle neck in a position in which the registration feature has a predetermined orientation to the bottle neck rotationally about the axis. Preferably, the fitment has a screw thread defining a limit of rotation for a bottle cap to be screwed onto the fitment. The registration feature has a predetermined orientation to the screw thread rotationally about the axis, whereby the limit of rotation also has a predetermined orientation to the bottle neck rotationally about the axis.
Description
- This application is a divisional of utility U.S. patent application Ser. No. 13/656,170, filed Oct. 19, 2012, which claims the priority benefit of provisional U.S. patent application 61/550,482, filed Oct. 24, 2011.
- This technology includes bottles that have fitments installed in the bottle necks.
- Plastic bottles can be formed from plastic film. One or more webs of the plastic film are unrolled from spools, and are folded and seamed together to form structures known as a preforms. Each preform corresponds to an individual bottle, and has a generally flat shape defined by the flat panels of plastic film. A fitment may be installed in the neck of the preform to provide a spout. The preform is then placed inside a blow-molding cavity that has the size and shape of the bottle, and is expanded under fluid pressure inside the cavity. This deflects the plastic film into the shape of the bottle.
- A cylindrical fitment has an axis and a registration feature. The fitment is sealed within a bottle neck in a position in which the registration feature has a predetermined orientation to the bottle neck rotationally about the axis.
- Preferably, the fitment has a screw thread defining a limit of rotation for a bottle cap to be screwed onto the fitment. The registration feature has a predetermined orientation to the screw thread rotationally about the axis. Accordingly, the limit of rotation also has a predetermined orientation to the bottle neck rotationally about the axis.
- In a method of assembling a bottle with a fitment, a cylindrical fitment is mounted on an insertion tool in a position in which a registration feature on the fitment has a predetermined orientation to the insertion tool rotationally about an axis of the insertion tool. The insertion tool is moved to a position in which the mounted fitment is located within a bottle neck, and in which the insertion tool has a predetermined orientation to the bottle neck rotationally about the axis. This establishes a predetermined orientation of the fitment relative to the bottle neck rotationally about the axis. The fitment can then be secured to the bottle neck in the established orientation.
- The bottle neck is preferably defined by a plastic bottle preform web structure. The secured fitment and the web structure are placed into a blow-molding cavity in a position in which the registration feature on the fitment has a predetermined orientation rotationally relative to a registration feature of the mold cavity. This establishes a predetermined rotational orientation between the web structure and the mold cavity. The web structure can then be blow-molded into a bottle having a predetermined rotational orientation with the fitment.

FIG. 16 is a perspective view of a blow molding apparatus. - A
plastic bottle 10 is shown inFIG. 1 . In this particular embodiment, thebottle 10 has a square cross-sectional shape with afront face 12, arear face 14, and a pair of opposite side faces 16. Afitment 20 projects upward from aneck portion 22 of thebottle 10. Thefitment 20 is configured and arranged to receive abottle cap 28 in a specified position relative to theneck 22 and other parts of thebottle 10. Specifically, when thecap 28 is screwed fully onto thefitment 20 as shown inFIG. 1 , anon-cylindrical portion 30 of thecap 28 has a predetermined orientation relative to thefront face 12 of thebottle 10. - As shown in greater detail in
FIGS. 2-4 , this example of afitment 20 is a cylindrical tube with acentral axis 31. Alower section 32 of the fitment hasribs 34 for gripping to thebottle neck 22. Anintermediate section 36 of thefitment 20 has a registration feature. In the preferred embodiment the registration feature is a flat 38 that extends lengthwise as chord relative to the circular peripheral shape of thefitment 20. Anupper section 40 of thefitment 20 has ascrew thread 42. - The
screw thread 42 on theupper section 40 of thefitment 20 is configured for thecap 28 to be screwed onto thefitment 20, and defines a limit of rotation of thecap 28 about theaxis 31 relative to thefitment 20. The flat 38 on thefitment 20 has a predetermined orientation circumferentially about theaxis 31 relative to the limit of rotation defined by thescrew thread 42. This ensures that thecap 28 will have a correspondingly predetermined orientation relative to thefitment 20 rotationally about theaxis 31 when thecap 28 is screwed fully onto thefitment 20. - As shown in greater detail in
FIGS. 5-7 , thecap 28 has a shortcylindrical body 50 with acentral axis 51. Atop wall 52 of thebody 50 has aspout 54. Aninsert 56 is fitted closely into thebody 50 from beneath, and has ascrew thread 58 for engaging thescrew thread 42 on thefitment 20. - The
non-cylindrical portion 30 of thecap 28 is a feature that renders it asymmetrical circumferentially about theaxis 51. In the illustrated embodiment, thenon-cylindrical portion 30 of thecap 28 is a rectangular flip-top extending diametrically across thetop wall 52. Ahinge 60 enables the flip-top 30 to move pivotally back and forth between the closed and open positions ofFIGS. 5 and 6 . In accordance with the predetermined rotational orientations of thecap 28 and thefitment 20, the flip-top 30 in this example extends longitudinally in a direction perpendicular to the lengthwise direction of theflat 38 when thecap 28 is screwed fully onto thefitment 20. - The
bottle 10 in the illustrated embodiment is formed from a plastic film web structure.FIG. 8 shows an example of aweb structure 100 that can be used to manufacture thebottle 10. In this cross-sectional view, theweb structure 100 is shown to include four panels of plastic film. These include afront panel 102, arear panel 104, and twogusseted side panels 106. The web panels 102-106 are arranged together along the length of theweb structure 100 to formmultiple bottles 10 having the front, rear and side faces 12, 14 and 16 shown inFIG. 1 . -
FIGS. 9-12 show a method and apparatus for assembling parts of thebottle 10. Theweb panels rollers 120 to form theweb structure 100 downstream of therollers 120. Afitment insertion tool 122 includes amandrel 124 with anaxis 125, and further includes adriver 126 that is operative to advance and retract themandrel 124 axially into and out of theweb structure 100. - When the
mandrel 124 is being advanced toward the position shown inFIG. 9 , it carries afitment 20 toward and between the panels 102-106 to place thefitment 20 within theweb structure 100. Themandrel 124 is then retracted. In the next step, a pair of grippers 130 (FIG. 10 ) move into engagement with thefitment 20. Thegrippers 130 form a heat seal that fixes thefitment 20 to theweb structure 100, and also pull thefitment 20 and theweb structure 100 downward from the position ofFIG. 9 to the position ofFIG. 10 to advance another section of theweb structure 100 downward between therollers 120. A seamingpress 140 then acts upon theweb structure 100 to form seams that attach the panels 102-106 together, as shown inFIG. 11 . - Specifically, as shown in
FIG. 12 , the seamingpress 140forms seams 142 at the bottom of the leadingsection 144 of theweb structure 100, andforms seams 146 at the top and sides of a trailingsection 148 of theweb structure 100. This forms theneck 22 in which thefitment 20 is to be inserted. The seamingpress 140 also cuts outextraneous portions 150 of theweb structure 100, and severs the leadingsection 144 from the trailingsection 148 at acut line 151. The leadingsection 144 is thus assembled as abottle preform 152 with aneck 22, and the process repeats to form multiple bottle preforms 152 successively in this manner. - As thus far described, the method and apparatus for forming a preform web structure, and for inserting a fitment into the neck of a preform web structure, are substantially similar to the method and apparatus disclosed in U.S. Pat. No. 7,147,597, which is incorporated by reference. U.S. patent application Ser. No. 12/813,216, filed Jun. 10, 2010, which also is incorporated by reference, describes additional web-forming and fitment insertion methods and apparatus that are suitable for adaptation to the present invention.
- In the preferred method of inserting a fitment with a registration feature, a track 160 (
FIGS. 13-15 ) feeds thefitments 20 to themandrel 124. Thetrack 160 is inclined so thatfitments 20 loaded at the upper end of thetrack 160 will slide toward the lower end under the force of gravity. When afitment 20 reaches agate 166 at the lower end of thetrack 160, aspacer bar 168 is moved across thetrack 160 to interrupt movement of thefitments 20. Themandrel 124 is then moved downward into engagement with thefitment 20 in thegate 166, andsections 170 of thegate 166 are opened to allow themandrel 124 to move the engagedfitment 20 downward into theweb structure 100 as described above. Thespacer bar 168 is then retracted to allow the nextsuccessive fitment 20 into thegate 166. - As shown in
FIG. 15 , thetrack 160 in this example has a pair ofside walls 182 that are spaced apart a distance that is just slightly greater than the diameter of afitment 20 at thelower section 32 of thefitment 20. Arail 184 projects transversely inward from oneside wall 182 at the height of the flat 38 on afitment 20. Thetrack 160 thus configured to receive a row of thefitments 20, with theflats 38 on thefitments 20 adjoining an inner edge of therail 184. This permits afitment 20 to be mounted on thetrack 160 in only one orientation rotationally about theaxis 31 of thefitment 20. Thetrack 160 delivers thefitment 20 to themandrel 124 in the same orientation rotationally about theaxis 125 of themandrel 124. - The orientation of the
fitment 20 on themandrel 124 has a predetermined relationship to theweb structure 100. In the illustrated embodiment, this is accomplished by advancing thefitments 20 along thetrack 160 toward themandrel 124 in a direction parallel to theaxes 189 of therollers 120 that guide the panels 102-106 together into the configuration of theweb structure 100. When themandrel 124 moves thefitment 20 into theweb structure 100 along theaxis 125, it does not rotate thefitment 20 about theaxis 125, but instead maintains thefitment 20 fixed relative to therollers 120 and theweb structure 100 rotationally about theaxis 125. In this example, themandrel 124 thus inserts eachfitment 20 into theweb structure 100 in an orientation in which the flat 38 extends lengthwise in a direction parallel to the front andrear panels fitment 20 is then heat-sealed to theneck portion 22 of thebottle preform 152 in the same orientation rotationally relative to theweb structure 100. This provides a correspondingly predetermined orientation between thepanels preform 152, the flat 38 on thefitment 20, and the rotational limit of thebottle cap 28 on thefitment 20. In the illustrated embodiment, that predetermined orientation ensures that the flip-top portion 30 of thecap 28 will extend lengthwise in a direction perpendicular to the front and rear faces 12 and 14 of thefinished bottle 10, with thehinge 60 at the rear, when thecap 28 is screwed fully onto thefitment 20 as shown inFIG. 1 . - Although the given example of a
fitment 20 has a single flat 38,multiple flats 38 or other registration features could provide multiple corresponding orientations between thepanels preform 152, the registration feature on thefitment 20, and the rotational limit of thebottle cap 28 on thefitment 20. For example, a pair offlats 38 at diametrically opposite locations on thefitment 20 would provide a pair of orientations that are offset from each other by 180 degrees. - As shown in
FIG. 16 , a pair ofmold structures preform 152 for blow-molding of thepreform 152 into afinished bottle 10. When themold structures side panels preform 150 are expanded to the size and shape of the front, rear, and side faces 12, 14 and 16 of thebottle 10.Neck portions 196 of themold structures neck portion 22 of thebottle 10. One of theneck portions 196 has a registration feature in the form of arail 198 projecting radially inward. Therail 198 on themold structure 190 is configured to register with the flat 38 on thefitment 20 in thepreform 152. This helps to ensure that thepanels preform 152 will be expanded into abottle 10 in which thefitment 20, and abottle cap 28 screwed onto thefitment 20, will have the predetermined rotational orientations described above. - This written description sets forth the best mode of carrying out the invention, and describes the invention so as to enable a person skilled in the art to make and use the invention, by presenting examples of elements recited in the claims. The patentable scope of the invention is defined by the claims, and may include other examples that occur to those skilled in the art. Such other examples, which may be available either before or after the application filing date, are intended to be within the scope of the claims if they have elements that do not differ from the literal language of the claims, or if they have equivalent elements with insubstantial differences from the literal language of the claims.
