Container carriers
Improved carriers and improvements in handling equipment to provide for accurate entry of carriers into machines for application of carriers to containers and to prevent inverted entry of carriers into machines for applying carriers onto containers.
Reference is made to my Provisional Application No. 60/555,642, filed Mar. 22, 2004, entitled “Improved Container Carriers”.
BACKGROUND AND SUMMARY OF THE INVENTIONThe present invention relates to carriers for containers for a variety of substances and materials. Such containers are generally fabricated of plastic or glass and have removable caps.
The present invention provides various improvements in carriers and related equipment.
The present invention provides improvements in bottling machines for use with such carriers, including a plurality of posts or rods spaced about a stack of carriers in such machine to maintain them oriented for accurate application of carriers to containers.
Tab portions on carriers engage components of carrier application machines. Tabs on carriers engage at entrance plate openings to prevent the insertion of inverted carriers.
Tabs on carriers are provided to engage the openings of carrier installing machines to prevent entry into the machine of inverted carriers.
BRIEF DESCRIPTION OF THE DRAWINGS
Referring to the drawings,
Referring to
As shown in

As shown in
The filling of containers is generally done by a machine having an upside-down suction cup member (not shown) which engages about the outer rim of respective carriers in succession to force each carrier ring down about a bottle cap on a filled container. If a carrier ring becomes lodged under the upside-down cup member of the machine, it will not be properly mounted ir will hot be mounted. This problem must be corrected with expensive delay and down-time with no production until the problem is corrected.
Referring to
If one or more carriers in a stack of carriers is disposed inwardly or is upside down at the opening 40 in machine plate 42 or, even worse, an upside-down carrier may be partially installed on a bottle by the machine, although upside down with a ring carrier portion hung up on the bottle cap. A serious problem results when a person, such as a customer, picks up the container, in that the carrier may allow the filled container to fall from the carrier and fall to a floor or other surface, breaking the container, with possible resultant serious personal injury, and at least causing a substantial cleaning task.
A plurality of posts or rods 60 of
The posts or rods prevent carriers from passing upside down in the hopper. A cut-out at the bottom conforms to the posts or rods to prevent passage through the throat of the machine. The carrier tab is sufficiently stiff to resist its deflection. If a carrier is upside down it will not pass through. A non-symmetrical placement tab prevents the carrier from being loaded in the hopper upside down. Any carrier in any stack cannot be upside down because the eccentric placement tab interferes with hopper supports. A small tab or finger lays in the same direction so that an eccentric tab is not needed.
Claims
1. A container carrier comprising:
- a generally circular carrier member, and
- a tab extending from said carrier member to engage a machine intake opening edge to prevent entry of an inverted carrier into an intake opening of a machine for the mounting of successive carriers on respective containers, whereby entry of inverted carriers into said machine is prevented.
2. A carrier according to claim 1, wherein a ring portion of a carrier is prevented from being retained on a bottle cap being pressed about a container rim.
3. A container carrier according to claim 1, wherein the tab extending from said carrier is adapted to engage a side edge portion of an opening of the machine to prevent insertion of inverted carriers into an input opening of the machine, whereby incorrect insertion of an inverted carrier is prevented.
4. A container carrier according to claim 1, wherein the tab extends radially from the carrier periphery for prevention of inverted entry of the inverted carrier into a bottling machine for mounting the successive carriers on successive containers.
5. A combination according to claim 4 and further comprising a machine intake opening adapted to receive said tab on the side edge portion of said machine intake opening.
6. A combination according to claim 5, and further comprising a plurality of rods disposed about stacked carriers in a machine to retain the carriers in alignment for application to successive containers.
7. A combination according to claim 6 wherein said carriers are of generally elliptical cross-section to economize in ring material without substantial reduction in rigidity.
8. A container carrier comprising:
- a carrier member of generally circular configuration,
- said carrier member having two handles extending oppositely from the carrier member for upward manual bending and grasping of the handles, and
- tab means extending from the carrier to prevent insertion thereof upside-down into a bottling machine by extension of the tab into an edge portion of a bottling machine intake opening.
9. A combination according to claim 8 wherein portions of said handles are at least partially elliptical in cross-sectional configuration, whereby costs of material are reduced.
