[0001]
BACKGROUND OF THE INVENTION
TECHNICAL FIELD The present invention relates to a container holder for holding a container in a container sealing device that seals a container having a flange portion extending outward from an opening edge of the container body with a lid member. The present invention relates to a container holder in which a flange support that supports a flange portion is securely fixed to a holder body, and when the flange support is replaced, the flange support can be easily attached and detached.
[0002]
[Prior art]
As a sealed container filled with food, etc., heat sealing is conventionally applied to a container made of plastic, such as polypropylene, filled with food, etc., and a flange extending outward from the opening edge of the container body. And a lid made of a relatively thin plastic film having a heat-welding property, which is welded by the above-mentioned method. Such a container is sealed by, for example, a container sealing device as shown in FIG.
[0003]
This container sealing device includes a plurality of container holders 11 for intermittently transferring a plurality of containers 1 filled with food (not shown) and the like, a wound body 12 in which a band-shaped lid member 2 is wound in a roll shape, The guide rolls 13 and 14 for guiding the lid material 2 fed out from the winding body 12 onto the container 1 of the container holder 11 and the lid material 2 superimposed on the upper end surface of the container 1 filled with food are attached to the container 1. A sealing device 15 that heat-presses and heat-seals the flange portion, a trimming device 16 that cuts the lid material 2 along the outer periphery of the flange portion of the container 1, and a marking (not shown) of the lid material 2 for alignment. It is comprised roughly with the sensor 17 which reads.
[0004]
Here, as shown in FIGS. 10 and 11, the container holder 11 in the container sealing device has a plurality of container insertion holes 21 into which the container body 3 of the container 1 is inserted and is held in the container holder 11. Between the holder main body 23 in which an annular groove 22 for entering the cutter blade 18 of the trimming device 16 is formed so as to surround the outer periphery of the flange portion 4 of the container 1, and between the container insertion hole 21 and the annular groove 22. An annular flange support 25 made of an elastic material such as silicone rubber, which is bonded to the holder main body 23 with an adhesive 24, is schematically configured.
[0005]

Examples of such plastic films include polypropylene (PP), ethylene-vinyl alcohol copolymer (saponified ethylene-vinyl acetate copolymer, EVOH), polyethylene (PE), unstretched nylon, Examples thereof include a laminated film in which two or more of these single-layer films are appropriately combined and laminated.
[0020]
Next, replacement of the flange support in the container holder will be described.
When removing the flange support 35 from the holder body 33, first, the screw 37 that fixes the fixing portion 36 of the locking ring 40 to the bottom of the annular groove 32 of the holder body 33 is removed, and the locking recess of the flange support 35 is removed. The flange support 35 is removed from the holder body 33 together with the locking ring 40 in a state in which the locking claw portions 38 of the locking ring 40 and the locking ring 40 are fitted. Next, by elastically deforming the T-shaped vertical bar portion 42 of the flange support 35, the engagement between the locking recess 34 of the flange support 35 and the locking claw 38 of the locking ring 40 is released, and the flange support is performed. The body 35 is separated from the locking ring 40.
[0021]
When the flange support 35 is attached to the holder body 33, first, the locking recess 34 of the flange support 35 and the locking claw of the locking ring 40 while elastically deforming the T-shaped vertical bar portion 42 of the flange support 35. The flange support 35 is attached to the holder main body 33 together with the locking ring 40 in a state where the locking recess 34 of the flange support 35 and the locking claw 38 of the locking ring 40 are fitted. Install. Next, the fixing portion 36 of the locking ring 40 is fixed to the bottom portion of the annular groove 32 of the holder body 33 with a screw 37.

Further, the fixing portion 36 of the locking ring 40 is fixed along the bottom of the annular groove 32 of the holder main body 33, and the main body portion 39 of the locking ring 40 extends along the inner peripheral wall of the annular groove 32 of the holder main body 33. Therefore, a sufficient space for allowing the cutter blade 18 of the trimming device 16 to enter the annular groove 32 can be secured.
Further, since the fixing portion 36 of the locking ring 40 is fixed along the bottom portion of the annular groove 32 of the holder body 33, the screw 37 fixing the fixing portion 36 to the bottom portion of the annular groove 32 of the holder body 33. Can be confirmed from above the container holder 30, and a tool such as a screwdriver can reach the screw 37 directly from the opening of the annular groove 32, so that the screw 37 can be easily attached and detached.
[0024]
Further, since the locking recess 34 of the flange support 35 is formed so as to extend in the circumferential direction along the outer peripheral side surface of the flange support 35, the annular locking ring 40 is formed on the entire outer peripheral side surface of the flange support 35. The flange support 35 is securely engaged with the engagement recess 35 of the flange support 35.
Further, since the holder body 33 is formed with an annular convex portion 41 along the periphery of the container insertion hole 31, flange support is provided between the annular convex portion 41 and the locking claw portion 38 of the locking ring 40. The T-shaped vertical bar portion 42 of the body 35 can be clamped. Thereby, the flange support 35 is reliably fixed by the holder main body 33.
[0025]

For example, the shapes of the holder main body and the flange support are not limited to those shown in the drawings, and can be changed as appropriate according to the shape of the container and its flange. Further, the locking portion of the flange support is not limited to the concave shape in the illustrated example, and may be a protrusion or the like as long as it can engage with the locking member.
Further, the shape of the locking member is not limited to the L-shaped one in the illustrated example as long as a sufficient space for allowing the cutter blade of the trimming device to enter the annular groove can be secured.
[0026]
Further, the locking member is not limited to an annular member that engages with the flange support over the entire outer peripheral side surface of the flange support as shown in FIGS. 6 and 7, and is a flat plate as shown in FIG. 8. A locking member 50 including a fixing portion 51, a flat plate-like main body portion 52 bent at a right angle from a side edge of the fixing portion 51, and a locking claw portion 53 formed by bending the tip of the main body portion 52. Alternatively, a plurality of the locking members 50 may be used to partially engage with a plurality of locations on the outer peripheral side surface of the flange support.
Further, the means for fixing the locking member to the holder main body is not limited to a screw as in the illustrated example, and any other fastening means such as a bolt may be used as long as the locking member can be detachably fixed. May be used.
[0027]
