Piazze, Mount Vernon, Ohio, assignor to Continental Can Company, Inc., New York, N. Y., a corporation of New York Application August 5, 1954, Serial No. 448,067
Claims. (Cl. 225-406) This invention relates to packaging and is more par,- ticularly concerned with improvements in apparatus for use in packaging merchandise in successive containers in a rapid and efficient manner.
It is a general object of the invention to provide apparatus for use in packaging merchandise in flexible containe'rs, which containers are formed of a continuous plastic film material, or the like, and which are supplied in connected roll form.
It is a further object of the invention to provide apparatus for use in packaging merchandise in containers which are formed of relatively flexible and limp material, such as a plastic film, and which are supplied to the operator in connected series, the apparatus being adapted to facilitate separation of successive containers from the source of supply and presentation of the same, with the mouth thereof in open condition, to a filling funnel, or the like, for receiving therein a predetermined quantity of the merchandise which is to be packaged.
It is another object of the invention to provide an apparatus for facilitating the handling of a plurality of containers which are formed of plastic film material and which are supplied to the apparatus in connected series or roll form, which apparatus is so arranged that the operator. is able to Withdraw a single container from the supply thereof and separate the same from the next succeeding container by a tearing operation.
It is another object of the invention to provide a mechanism for use in dispensing merchandise containers or.
bags which are supplied in connected series or roll form which comprises a support for a roll of the bags and associated apparatus permitting the bags to be withdrawn and removed from the roll, which apparatus includes an abutment member adapted to project through an aperture in a perforated line separating each bag in the roll from the next succeeding bag as the bags are unwound from the roll and moved in a predetermined path past the abutment member, whereby the endmost bag may be separated from the end of the roll by tearing along the perforated line separating it from the next succeeding bag while the next succeeding bag is held against advancing movement by engagement with the abutment member.
These and other objects and advantages of the invention will be, apparent from a consideration of the apparatus and the method of using the same which is illustrated in the accompanying drawings, wherein:
Fig. 1 is a front perspective view of apparatus arranged for dispensing a roll of connected containers which embodies the principles of the invention;
Fig. 2 is a rear perspective view of the apparatus;
Fig. 3' is a sectional view taken on the line 3-3 of Fig. 1, to an enlarged scale;
Fig. 4 is a perspective view of a roll of the container material; and
Fig. 5 is a perspective view illustrating the separation of the containers. 1
Referring first to Fig. 4 of the drawings, there is illus- 2,"i4,88t5 Patented Feb. 24, 1959 is... trated a supply roll 10 of the containers 11 with which the dispensing mechanism is adapted to be employed. The roll 10 comprises a plurality of the connected containers 11, each of which is formed from a section of flat tubular material which is initially provided with infolded sides or bellows fold formations 12. Each of the containers 11 is separated from the adjoining container in the roll 10 by a transverse seal formation 13 and a perforated transverse tearing line 14 which is provided adjacent the transverse seal 13. The perforated tearing line 14 preferably comprises a center slit 15 of substantial width and a plurality of smaller slits or perforations extending from the center slit 15 to opposite side edges of the tube.
The dispensing apparatus 20 (Figs. 1 to 3) which is adapted to support the roll 10 for ready removal therefrom of the individual containers 11 comprises a circular support plate 21 which is preferably positioned in vertical or upright relation relative to a horizontal supporting surface. The plate 21 is secured to an upright frame forming bar or plate 22 having cross bars 23 and 24 at,
opposite ends. The lower end cross bar 23 is provided at its opposite ends with laterally extending parallel rods 25 and 26 which are adapted to cooperate with the end cross bar 23 to provide a U-shaped bottom supporting frame when the apparatus is supported on a table top or other horizontal surface. The top end. cross bar 24 is apertured at opposite ends at 27 and 28 to permit the apparatus to be fastened to a vertical or overhead support. .A handle forming bar or rod member 29 extends laterally of the cross bar 24 intermediate its ends to facilitate handling of the apparatus.
, The roll 10 is adapted to. be rotatably mounted on a cylindrical supporting member 30 which extends laterally of the frame member 22. The free end 31 of the web The shaft 36 carries adjacent its free end a cross pin 38 which is slidably mounted in a radial aperture 39 with a removable cotter pin 40 at one end; and a guide roller 41 rotatably mounted on the other end for bearing against the end edge of the core 42 of the roll 10 to retain the roll 10 in proper alignment on the support 30.
The end 31 of the web material passes from the takeup roller 32 beneath a fixed guide roller, 43 (Figs. 1 and 3) which is rotatably mounted on a shaft 44 extending laterally of a supporting bracket formation which comprises the horizontal bar or plate 45 extending from the main vertical support member 22 and a vertically extending bar or plate 46 mounted on the end of support bar 45. The guide roller 43 is arranged in parallel relation with take-up roller 32 and the roll support '30. A rod 47 extends laterally of the vertical support plate 46 immediately above the guide roller 43 and provides a supporting member for an abutment pin 48 which projects outwardly beyond the surface of the adjoining guide roller 43. The abutment pin 48 is provided in its outer free end with an axially extending vertical slot 49 and a disk-like roller 5t) of relatively small diameter is journaled therein which bears against the web material as it is pulled by the operator in a vertical direction upwardly of the guide roller 43.
The web material is held against the surface of the guide roller 43 by a spring plate 51 which is clamped to a supporting bar member 52 extending from the vertical support member 46 by means of a clamp bar 53 and cooperating clamp bolts 54. The spring plate 51 is formedof relatively thin resilient plate material and is curved at 55 adjacent its upper end to conform to the curvature of the roller 43 andtopressthe web material against the same. t
In using theapparatus-the frame is set up as desired and securedin place. The roll'of material is secured on the support member 3% by lifting the pin 38 sufiicien't' to pass the hollow core '42of the roll over the same. Thereafter, the "free end 31 of the roll 10 is threaded over the take-up roller 32, beneath the guide roller 43' and upwardly between the roll Bend the spring plate rnem 51 in urging the same toward the roller'43, which is im mediate'ly'belo-wthe pin 48, and the'tension in the ma ter'ial due tothe operators pull on the same in the vertical direction. The individual containers llma'y thenv be separated from the supply roll 10 by pulling upwardly on the same until thepin 48 engages in the center slit in =theiperforated tearing-line 1'4 and penetrates the web material as shown iii-Figs. 3' and 5. Continued-pull on the end of the material "causes the end to tear off on the perforated line 14, while the adjoining portion of the'material is held against advancing movement by the abutmentpin 48 as shown in Fig. 5.
