3A is a front view (cross-sectional view) of the preform 5 as a pre-molded body before blow molding of the container body 2, and FIG. 3B is a bottom view.
The preform 5 is formed by a compression molding machine, and an upper neck portion 3a of the preform 5 which is a portion that becomes the mouth neck portion 3 of the container body 2 is formed at the upper portion, and a preform is formed at the lower portion of the mouth neck portion 3a. An annular flange 23 projecting outward in the radial direction is formed, and a body portion 9 as a blow-molded portion is provided at a lower portion of the annular flange 23. The trunk | drum 9 is formed in the thickness which can be extended | stretched at the time of blow molding.
The bottom 6a of the preform 5 has a mold number a (02 in the figure) and a cavity mold number b (20 in the figure, hereinafter referred to collectively as the production numbers after the preform 5 is blow-molded). A label 7 on which the production numbers a and b) are displayed is attached. These serial numbers a and b are attached to the inner surface or the outer surface of the center portion of the bottom portion 6 a of the preform 5.

Next, a compression molding machine for the preform 5 and its related devices capable of mounting the label 7 on the bottom 6a will be described.
The mold 10 of the compression molding machine is provided with, for example, a plurality of cavity molds 11 arranged concentrically as shown in FIG. The mold 10 is provided with a molten resin conveying device 25 adjacent thereto, and a plurality of molten resin drop supply members 15 are rotatably arranged on the conveying device 25. The molten resin is cut from the molten resin supply device by the position X below the molten resin discharge port 24, received, rotated by a predetermined angle, and then the molten resin is cavityd at a position Y corresponding to the cavity mold 11. It is configured to be supplied into the mold 11.

  On the upstream side of the position Y, a label supply device 28 shown in FIG. In the label supply device 28, the rod 30 supported by the rotary lift unit 29 is provided in an upright state, and an arm 31 extending in the horizontal direction is attached to the upper end side of the rod 30. The arm 31 can move up and down according to the lifting and lowering of the rod 30 by the rotary lifting unit 29, and is configured to rotate about the rod 30 as an axis. A label support member 32 that extends downward is attached to the tip of the arm 31. A suction part 32a in which a suction hole is formed is provided at the tip of the label support member 32, and the suction part 32a is stopped by sucking and sucking the label 7 by a suction device 33 capable of sucking air. The label 7 can be dropped onto the cavity mold 11. If a system capable of intake and exhaust is used instead of the suction device 33, for example, a system capable of intake and exhaust by moving the piston back and forth, such as a syringe, when the label is dropped, the label is placed on the suction portion 32a by slightly exhausting. Since sticking can be prevented and a label can be dropped more smoothly, it is preferable.

The labels 7 are assigned production numbers a and b corresponding to the corresponding cavity molds 11, and a set of labels 7 corresponding to the quantity of the cavity molds 11 is placed on the turntable 34. The label 7 is transferred while rotating the turntable 34, and the label 7 is sucked and supported by the label support member 32 by the rotation of the arm 31. As shown in FIG. 4, the rotation radius circle of the arm 31 of the label supply device 28 is in contact with the rotation radius circle of the cavity mold 11 of the mold 10, and the arm 31 is positioned just above the center of the cavity mold 11. The label 7 is dropped from the label support member 32 onto the cavity mold 11 by stopping the exhaust of the suction device 33.
Thus, the cavity mold 11 receives the label 7 at the position Z, and the molten resin is transported to the position Y where the molten resin is dropped onto the cavity mold 11 with the label 7 disposed on the bottom of the cavity mold 11.

Of the production numbers a and b, the mold number a identifies one of the molds 10 of the compression molding machine, and a plurality of cavity mold numbers b are provided in the mold 10. The individual cavity molds 11 are identified. For example, when there are 10 molds (sets) of the compression molding machine, numbers such as 01 to 10 can be given. Similarly, for the cavity mold number b, when 50 cavity molds 11 are provided in one mold 10, for example, numbers such as 01 to 50 can be given. Therefore, when the cavity mold number b of the present embodiment is 20 as shown in FIG. 2B, the subsequent cavity mold numbers are 21, 22 and 23, which are followed by consecutive numbers, The labels 7, 21, 22, and 23 are sequentially disposed in the cavity mold 11.
The label 7 may be printed and printed in advance, but a blank one is placed on the turntable 34 so that the cavity number of the cavity 11 is recognized and the turntable 34 is placed. For example, a number recognized by a high-speed printing machine such as an ink jet printer may be printed during the period from placement to dropping into the cavity 11.

Next, the preform compression molding procedure will be described.
FIG. 6A shows one of the cavity molds 11 arranged concentrically. The cavity mold 11 is formed with an inner hole formed in the vertical direction at the center thereof, and is rotated on a circular orbit separate from the cavity mold 11 on the cavity mold 11. 11 is configured such that the drop supply member 15 of the transport device having one contact in the vertical direction is instantaneously disposed at the upper position.
A neck half 16 that mainly forms the mouth-neck portion 3 of the container 1 is disposed immediately above the cavity mold 11, and the neck half 16 can move on the circular orbit of the cavity mold 11. The neck half 16 can be divided into right and left, and a through-hole 17 extending in the vertical direction is formed inside the neck half 16 (A in FIG. 6 is a situation diagram at position Y in FIG. 4).
A core 18 that can move on the track of the cavity mold 11 is disposed on the neck half 16, and the neck half 16 and the core 18 can move up and down while moving on the circular track of the cavity mold 11. It is configured.

As shown in FIG. 6A, when the drop supply member 15 of the transport device enters between the cavity mold 11 and the neck half 16 and moves on the same orbital point that is tangent to each other's orbit, the drop supply member 15 A drop (molten resin) 21 is supplied from 15 to the inner hole 14 of the cavity mold 11 and dropped onto the label 7. Thereafter, the drop supply member 15 is separated from the orbit of the cavity mold 11.
Next, as shown in FIG. 6B, the neck half 16 is lowered and disposed on the cavity mold 11, and then the core 18 is lowered. As shown in FIG. 6C, a gap is formed by being inserted into the through hole 17 and the inner hole 14 of the neck half 16, and the drop 21 fills the gap on the neck half 16 side (molding start of FIG. 4). Position reference). Thus, the drop 21 is compressed into the core 18 to form the preform 5 made of molten resin (see the molding completion position in FIG. 4). At this time, the label 7 is attached to the outer bottom portion of the preform 5 by the adhesive force (welding force) of the drop 21. Since the temperature of the drop 21 is about 280 ° C., even if the label 7 is paper, synthetic resin, or the like, it is a temperature that can be sufficiently tolerated if it is made of a normal material.

  As shown in FIG. 6C, after the compression molding of the preform 5 is completed, the core 18 and the neck half 16 are raised, and as shown in FIG. 5 can be removed from the core 18 and conveyed to the next process by a conveying means (not shown). In this way, the label 7 is mounted on the outer surface side of the bottom portion 6 of the preform 5 as shown by an arrow W in FIG. A label 7a in FIG. 7 shows a state in which the label is attached to the inner surface side of the preform 5 described later.

Such a preform 5 is blow-molded (not shown) in the next step.
In blow molding, the container body 2 is molded from the preform 5 using the heat of an infrared lamp or the like. At this time, if the material of the label 7 is weak against heat, a blindfold plate may be disposed between the label 7 and the infrared lamp so that the label 7 is not directly irradiated with the light of the infrared lamp. At the time of blow molding, since the label 7 is disposed at the center of the bottom portion 6 of the preform 5, the preform 5 is stretched at the time of blow molding, but the bottom portion 6 is a relatively unstretched portion. Less affected.
Thus, when sticking a label on the bottom 6 of the container body 2, if the label 7 is pasted on the bottom 6a of the preform 5 in advance, it is easier than pasting the container body 2 after molding. Further, since the production numbers a and b are attached to the bottom portion 6 of the container body 2, the cap is opened to determine which of the container molds 2 is formed of the cavity molds 11 among the plurality of cavity molds 11. It can be confirmed without. In addition, mounting the label 7 on the outside of the container body 2 has an advantage that the room for selecting the material of the label 7 is widened because the quality of the beverage is not affected.

Next, a second embodiment of the present invention will be described. In addition, about the same part as the said embodiment, the same code | symbol is attached | subjected and demonstrated. However, the label attached to the inside of the container body 2 is the inner label 7a, and the label attached to the outside as in the first embodiment is distinguished from the outer label 7.
In the first embodiment, the outer label 7 is attached to the outside of the bottom portion 6a of the preform 5. However, as shown by the arrow W in FIG. 7, the inner label is placed inside instead of the outside of the bottom portion 6a. 7a is attached.
In the label supply device 28 shown in FIG. 8, a rod 30 supported by a rotary lifting unit 29 is provided in an upright state, and an arm 31 extending in the horizontal direction is attached to the upper end side of the rod 30. The arm 31 can move up and down according to the lifting and lowering of the rod 30 by the rotary lifting and lowering unit 29, and is configured to rotate around the rod 30 as an axis. A label support portion is provided at the tip of the arm 31 and can be supported so as to place the inner label 7a. The label support portion 35 is connected to the suction device 33, and can hold the inner label 7a by a suction force. However, the inner label 7 a may be simply placed on the label support portion 35.

In the first embodiment, the inner label 7a is dropped on the bottom 6a of the cavity mold 11, but in this embodiment, the inner label 7a is supported on the lower end of the core 18. The inner label 7a can be supported on the core 18 by applying a simple adhesive or the like to the lower portion of the core 18 or the upper surface of the inner label 7a. Further, it is preferable to attach water or the like between the label 7a and the core 18 instead of the simple adhesive because the contents to be filled and the core 18 are not adversely affected when it becomes a container.
Since the preform molding process by the compression molding machine is the same as that of the first embodiment except that the inner label 7a is attached to the core 18, it is omitted. When the compression molding is completed, the inner label 7a is attached to the inner surface side of the bottom portion 6a of the preform 5 as shown in FIG.

  The preform 5 has the container body 2 formed by blow molding. As described above, blow molding is performed by irradiation heat such as an infrared lamp. However, since the inner label 7 a is attached to the inner surface side of the preform 5, the outer label 7 is attached to the outer side of the preform 5. Compared to almost no problem. After the blow molding of the preform 5 is completed and the container main body 2 is formed, the inner label 7a is attached to the inner surface side of the bottom portion 6 of the container main body 2, so that the material of the inner label 7a has an oxygen absorbing function. If a film, a far-infrared film, or the like is used, not only the production numbers a and b of the preform 5 can be confirmed, but also the quality of the contents can be maintained. The inner label 7a is particularly effective when it is necessary to prevent the label from being peeled off.

The embodiments of the present invention have been described above. However, of course, the present invention can be variously modified or changed based on the technical idea of the present invention.
In the above embodiment, the labels 7 and 7a are attached to the preform 5 of the container body 2. However, in the present invention, the label is attached to the outer surface or the surface of the ceiling wall of the cap when the cap is molded by the compression molding machine. can do. The cap manufacturing method in this case can be molded in the same process as the preform molding method shown in FIGS. 5 to 8 (blow molding is not performed), and has the same effect as the preform molding. There is an effect.
In each said embodiment, although the manufacturing number of the preform 5 or the container main body 2 was attached | subjected to the labels 7 and 7a, you may attach | subject the information of the molten resin which forms a preform, the information on the drink side, etc. , Patterns, patterns, etc. may be decorated (refer to the “Pura” design in the variation in FIG. 2).
In the first embodiment, the outer label 7 is used, and in the second embodiment, the inner label 7a is used. However, as shown by the arrow W in FIG. Also good. However, the thickness of the bottom is increased.
