[0001]

The present invention relates to an improvement of the packaging mirror rice cake.

[0002]

2. Description of the Related Art From a transparent or translucent thermoplastic synthetic resin, an upper small container and a lower large container are formed as concentric circles in plan view, and are blow-molded in a state of internal communication to form a mirror cake .
The present inventor has already disclosed a packaging container and a method and an apparatus for pouring and enclosing freshly ground hot rice cake into the packaging container, as disclosed in Japanese Utility Model Application Laid-Open No. 58-116573 and 59-30801.
No., No. 59-27760, 62-13495
No. 63-23342, No. 1-20302, No. 59-5266, No. 59-35579, Japanese Patent Application Laid-Open No. 5-178368, etc. Was completed.

The above-mentioned prior art is disclosed in
No. 116573 describes that the thickness of the sealing piece (7) welded to the bottom (3) of the container body (1) is made thinner than the thickness of the container body (1) itself. Even if the rice cake poured into the container body (1) in a full state by the sealing piece (7) is subjected to a boil action on sterilization and then shrunk and hardened to a volume reduced state by natural drying (cooling). In this case, the container body (1) does not undergo any irregular deformation such as a dent, so that only the sealing piece (7) is necessarily recessed from the bottom (3) of the container body (1).

[0004] On the other hand, since the Japanese Patent Laid-Open No. 5-178368 for facilitating the longitudinal split dismantling of packaging <br/> mirror rice cake, the center of the top surface of the upper <br/> stage small container of the packaging container (11) Department (North Pole)
Starting from (a), the portions (f) and (g) where the equator line of the small container (11) and the equator line of the lower large container (12) intersect with the virtual meridian (zz) are changed to other portions. It is disclosed that blow molding is performed to the thinnest wall thickness.

[0005]

[SUMMARY OF THE INVENTION However, the above known technique has still the following problems, and external shape important as commercial value of this type packaging mirror rice cake, resulting in the inhibition of Contents of reliability.

That is, referring to the above-mentioned Japanese Patent Application Laid-Open No. 5-178368, a seal cover (34) for sealing a rice cake pouring opening (17) at the center of the bottom surface of a mirror- shaped packaging container (filling container) is provided. The thinnest part of the container (a)
(F) Even if the thickness is further reduced as compared with (g),
The mochi covered by this is poured into the container.
Pour in a full state almost flush with the opening plane of the mouth (17)
When filled, the rice cake is sealed by welding the seal cover (34), and then immersed (boiled) in hot water for sterilization, whereby the container itself and the seal cover (34) are integrated. Once the expanded rice cake is naturally dried (cooled) and subsequently shrinks and hardens, when the container itself and the seal cover (34) are suctioned from inside, the amount of shrinkage of the rice cake is reduced by the above-mentioned amount. It is difficult to completely absorb and compensate only by the dent deformation of the seal cover (34), so that not only the seal cover (34) but also the central portion of the thinnest top surface (corresponding to the so-called weak point of the container itself) (North Pole) (a) does not mean that there is no risk of dent deformation.

Even if the lid is closed and the seal cover (34) is provisionally thinned compared to the container itself, the diameter (s2) of the rice cake pouring opening (17) sealed by this is a special shape.
It has a small size as that of a packaging container blow-molded in a shape , and the allowable deformation range of the seal cover (34) itself is limited to a narrow range. On the other hand, the diameter (d2) of the upper small container (11) in the container is considerably larger than the diameter (s2) of the rice cake pouring port (17),
Moreover the curvature radius is significantly larger for the top surface, on the relationship between form a near horizontal plane shape, for example or a Should too small amount pouring rice cake with respect to the container, or contraction of the rice cake is or changed, the The amount of shrinkage was measured using the seal cover (3
If it is not possible to absorb or compensate even a little due to the dent deformation of 4),
This is because the central portion of the top surface (the north pole) (a), which is a weak point of the container, is immediately dented by the shortage. The suction force accompanying the shrinkage of the rice cake concentrates on the central part (North Pole) (a) of the top surface of the container.

[0008] In addition, the rice cake that has just been milled into the container
Full shape almost flush with the opening plane of the pouring opening (17)
After filling, the volume of rice cake is reduced by subsequent cooling.
Is shrunk and hardened to a reduced state, and the seal cover (34)
Will be deformed together with
May result in false indications to consumers.
It is not preferable as a sale product.

[0009]

A tapered melt projection group is shaped by, and exhibits its overall cross-section substantially saw toothed, and heating elements ensures adhesiveness of the heat sealer (welder) to be described later to its previous
The heating effect can be concentrated on the apex of the thin projection. Further, the group of the molten protrusions (16) is of the large container (12).
Protruding outward from the bottom surface (15) by a certain band width (z)
Therefore, the bottom surface (15) is used as a reinforcing rib for thickening.
Would be helpful. The large and small containers (11) (1)
Needless to say, both the circumferential body surface of 2) and the top surface of the small container (11) have an arc-shaped convex surface protruding outward.

Next, FIGS. 2 and 3 show a rice cake pouring and filling machine (B).
(17) is an installation base plate with a free wheel (18), (19) is a hollow support that is vertically suspended from the center thereof, and a transmission case (20) is provided at the upper end thereof. It is fixedly installed.

Reference numeral (21) denotes an extrusion cylinder which is suspended from the lower front end of the transmission case (20) through the mounting bracket (22) almost in parallel with the hollow support (19).
The mid-height position is shaped like a funnel that expands forward, and a rice cake hopper (23) is connected to the funnel-shaped opening.

Further, (24) is an extrusion screw vertically suspended inside the extrusion cylinder (21), and (25) is a rotary shaft connected to and integrated with the upper end of the extrusion screw (24). It goes without saying that it faces the inside of the transmission case (20). (26) is the rotation axis (25)
Is a bearing case that supports the above-mentioned extrusion cylinder (2).
1), and is assembled and fixed via bolts (27).

(28) is a rotary drive motor of the extrusion screw (24), (29) is a speed reducer of the motor (28), and a drive pulley (30) is fixed to an output shaft thereof. (31) is an endless transmission belt wound around a driven pulley (32) fixed to the upper end of the rotating shaft (25) and a driving pulley (30).

Therefore, the extruded screw (24)
Is driven to rotate by the drive motor (28), and pushes the freshly polished rice cake (M) in a flowing state from the hopper (23) downward along the extrusion cylinder (21). (33) is a funnel-shaped aperture barrel which is flanged to the lower end of the extrusion cylinder (21) and fixed by bolts (34), and (35) is the aperture barrel (3)
The nozzle is connected to 3), and has a funnel shape whose lower end is opened downward.

Further, (36) is the transmission case (20).
The first switch of the manual push button type attached to the side surface of (1), (37) is the second switch of the foot type,

It is connected to the operation pedal (39) installed above.
The first and second switches (36) and (37) are electrically connected and wired to the drive motor (28), and by manually operating either of them, the motor (28) is turned on.
Can be started or stopped.

[0021] The hitting the enclosing poured inside to luck fresh cake of the packaging container (A) (M), while gripping the packaging container (A) above and below the opposite orientation state, FIG. 3, 4
The filling machine as a nozzle (35) to cast cakes from below port (B) (14) pledged, the packaging container (A)
The or turning, with or is further tilted by moving downward away from the nozzle (35) gradually, follicle
The rice cake (M) is poured and filled so that the rice cake (M) can be evenly distributed in the entire container (A).

Then, the rice cake (M) exceeds the full state of the packaging container (A) and overflows by an extra amount (h) from the opening plane (XX) of the rice cake inflow port (14) in the large container (12). Filling machine (B)
The stepping pedal (39) of the second switch (37) is depressed to stop the drive motor (28) of the extrusion screw (24), and the rice cake that hangs down from the nozzle (35) due to its own viscosity. (M)
Is cut off with a cutting tool (40) such as scissors.

In this case, the extra amount (h) of the rice cake (M) that overflows from the opening plane (XX) of the rice cake inflow port (14) is determined by the subsequent natural amount of the rice cake (M). The amount of shrinkage due to drying (cooling) is foreseen in advance from experience, and is subjected to the suction force at the time of the shrinking action.
4) Although the seal cover described below that seals the dent is deformed,
Small container, which is a weak Pont site of the packaging container (A) (1
Assuming that the central part (a) of the top surface of (1) is not depressed, the shrinkage of the rice cake (M) is set to a corresponding amount that can sufficiently absorb and compensate for the shrinkage of the rice cake (M) together with the seal cover.

In this respect, since the packaging container (A) is prepared in various sizes corresponding to the contents thereof, it is difficult to comprehensively define the excess amount (h) by specific numerical values. However, it is possible to know from the experience the shrinkage amount of the rice cake (M) and determine the fixed amount according to the individual packaging container (A). Further, the surplus amount (h) is Since the literally many eyes are meant to enclose the rice cake (M) in advance, there is a shortage in the content as a packaging mirror rice cake,
All it does not become the imaginary false display to the consumer.

As a final finished state (sale product) of the packaged mirror rice cake in which the rice cake (M) is shrink-hardened, the seal cover is flush with the opening plane (XX) of the rice cake pouring port (14). Is best, but shrinkage of rice cake (M)
Even if the provisional irregularities such as a slight bulging outward from the opening plane (XX) or a slight indentation from the opening plane (XX) are caused due to the variation in usage, the small The central part (a) of the top surface of the container (11) does not dent and deform , and
As long as there is not enough shortage of the contents to make a false indication, they belong to a certain allowable range as the extra amount (h).

As described above, the rice cake (M) is added to the packaging container (A).
After the filling is completed, the packaging container (A) is still in an upside-down state, and is placed in a receiving frame (41) of a heat sealer (welding machine) (C) as shown in FIG. The container (12) is set so that the bottom surface (15) of the container (12) is horizontal.

Then, the rice cake (M) in a state where the rice cake (M) is laid in an extra amount (h) from the opening plane (XX) of the rice cake pouring opening (14) is covered with a separate seal cover (42). The sealing cover (42) is heated by the heating element (43) of the heat sealer (C) to the large container (1).
The fusion protrusions (16) projecting from the bottom surface (15) of (2) are welded and integrated to keep the rice cake (M) in a sealed state.

In this case, as the seal cover (42), a back sheet (42a) of the same thermoplastic synthetic resin as the packaging container (A) itself as shown in FIG. 6 and a synthetic resin having higher heat resistance than this Table sheets (e.g., nylon) a slip sheet material with (42b), yet further using thin-walled than the thinnest part of the overall wall thickness packaging container thereof (a), the sealing cover (42) Back sheet (42
a) as shown in the partially enlarged view of FIG.
The heating element (43) is joined to the bottom surface (15) of (2).
The welding is integrated . (P) shows the welding position <br/> section min.

Then, the bottom (1) of the large container (12)
5), the back sheet (42) of the seal cover (42) is combined with the fact that the molten protrusion group (16) is provided.
Only a) can be welded and integrated with the packaging container (A) based on high affinity to prevent corrosion of the rice cake (M) due to invasion of air or moisture, while the surface sheet (42b)
Characters and graphics to guide the disassembling method of packaging rice cake, because it is possible to print without a risk of softening deformation
is there. Incidentally, the thin because it has a Table sheet (42b) is high heat resistance, as thick for backing sheet (42a) is melted, each on it is the function relating extraordinarily reasonable
It is a target.

However, the heat sealer (C) is not limited to one that causes the heating element (43) to generate heat by electricity, but may be one that generates heat by high frequency or ultrasonic waves. The packaging container (A)
The molten projection group (16), it can be said that capable of Okoshisei only one point centrally pressurized heat acting on the bonding interface.

The packaging container (A) has a diameter (d1) (d
2) Since the containers (11) and (12) are different in size from each other and each of the containers (11) and (12) has an elliptical shape stacked in a side view, the container is placed in an upside-down inverted posture state as shown in FIG. Heat sealer (C) receiving frame (4
The mounting setting can be stably performed to 1).

The heating element (43) of the heat sealer (C) is connected to the rice cake pouring port (1) in the packaging container (A).
It has an annular shape with a diameter (s3) larger than the diameter (s1) of 4), and further has a rice cake escaping concave groove (44) therein. That is, the seal cover (42)
The back sheet (42a) is the bottom surface (15) of the packaging container (A).
Group (16) provided as a constant band width (z)
Of which is a fixed distance from the edge of the rice cake pouring mouth (14)
At a position (p) separated outward by only (w),
That is, they are partially welded and integrated.

Therefore, when the seal cover (42) is welded, the heating element (4) of the heat sealer (C) is used.
According to 3), the edge of the rice cake pouring opening (14) is incorrectly deformed by heat, or the seal cover (42)
To the bonding interface between the large container (12), without fear or I sandwich the cake state marked with the prime (M), its
Condition that the excess amount (h) of rice cake (M) can be covered without leakage
Then, the back sheet (42a) of the seal cover (42)
Only you can be sure solid stability may integrally welded.

Further, the fusion protrusion group (16) has a constant band width.
Being provided in a concentric circle state over (z)
Is the heating element (43) of the heat sealer (C) and the container
(A) relative position deviation with the rice cake pouring port (14)
It also helps to absorb, and a slight misalignment occurs
Also, the seal cover (42) is combined with the molten protrusion group (16) .
Welding can be integrated reliably.

By welding the seal cover (42),
Once the mochi (M) has been sealed in its packaging container (A),
This can be continuously sterilized at a constant temperature (for example, about 80 to 10).
0 ° C) for a certain period of time (eg
For about 30 minutes).
Thus, the rice cake (M) is sterilized. Its boil action
Inside, rice cake (M) is packaging container (A) itself and its seal cover
It expands integrally with (42). In addition,
The posture state of the packaging container (A) during the action of the oil is as described above.
It is not limited to the opposite direction, and it is free.

The boil operation for sterilization was completed.
If the packaging container (A) is in a normal posture,
Subsequently, the rotation receiving frame (4) of the air processing machine (D) as shown in FIG.
5) From above, set it into the receiving frame (4)
5) Place the packaging container (A) around the vertical rotation axis (46).
Rotate at a constant speed (for example, about 100 to 1000 rpm)
To give the rice cake (M) a rotational centrifugal force.
This is tightly integrated with the inner peripheral surface of the packaging container (A).
Air bubbles at the interface are unsightly from the outside
Prevents seeing through.

At this time, air enters the packaging container (A).
If so, the air moves to the rotation center
And will not be discharged from the packaging container (A), but will be described later.
When the rice cake shrinks and hardens due to natural drying (cooling), the rice cake
(M) will be confined inside,
You can't see it.

Finally, the packaging container (A) is inserted into the container shown in FIG.
As is apparent from
Insert into the drying frame (47) from above and set
Air dry (cool) for a time (eg, about 12 hours)
By shrinking and hardening the rice cake (M) into a mirrored rice cake
It is finished in every sale product.

Then , the comparison between FIG. 9 and FIG.
As suggested, it once expanded due to the boil effect .
In the process of shrinking the rice cake (M), the packaging container
(A) Seal cover thinner than the thinnest part
(42) will be sucked from the inside first.
However, the bottom surface (15) of the container (A) is as described above.
In addition, the extra amount (h) of rice cake (M) overflows
Yes, the seal cover (42) covering this
Keeping the container (A) in a state of protruding outward from the bottom (15)
Because of the dent deformation action inward.
To absorb and compensate for the shrinkage of the rice cake (M)
