Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a blow-molded bottle with a handle, and particularly to a method for producing a bottle having a handle on the opposite side of a display label.

<Prior Art> In many blow-molded bottles with handles currently on the market, the handle and the label are disposed at right angles so that when the handle is grasped, the display label can be viewed directly.

However, if the labels are arranged at right angles in this way, if the label is viewed from multiple directions, it will be necessary to attach two sheets, but if the label is displayed at a store, or used by a large number of people at a party, etc., it will be necessary to attach one sheet. It is desirable to have a label on the opposite side of the handle so that the label can be viewed from multiple directions.

When attaching a label to such a bottle as an after-label after blow molding, the bottle must be placed on the belt conveyor on the line so that the handle is perpendicular to the flow direction, and the handle is attached to the support of the conveyor. There are times when you get caught, and the conventional I! There is a problem in that it requires a completely different system from the line for pasting labels on one side.

Also, as a method of attaching the handle to the bottle,
In Japanese Patent No. 91744, a technique is already known in which the handle attachment is made by embedding the component on the parting line of a proportion type, that is, at the seam of the mold, and the bottle and the handle attachment are integrated at the same time as blow molding. There is. Also, JP-A-63-9593
In Publication No. 1 or Japanese Patent Application Laid-Open No. 58-99350, the handle member itself is buried on the parting line of the proportion type, that is, in the seam of the mold, and the bottle and handle attachment are integrated at the same time as blow molding. There are already known technologies to do this.

Problems to be Solved by the Present Invention> However, in the above conventional method, as described above, the opposite side of the handle is also located in the part where the parting line will be generated after molding, and the label will be formed at the same time or after molding. In view of the above points, the present invention provides a mold that opens and closes in parts. In the method of molding a bottle by inserting a parison into a mold, clamping the mold, and blowing compressed air into the parison, the label is held on the inner surface of one of the split molds. After holding a handle member or a member for attaching the handle to a recess formed in a position opposite to the label of the other mold, the mold is clamped, and the bottle is blow-molded and the label is simultaneously molded. The present invention provides a method for manufacturing a bottle with a handle, characterized in that a handle member and the like are integrated.

Effect〉 By the above method, the label and handle can be formed at the same time as the bottle is formed.
Alternatively, the member for attaching the handle can be integrated, and the label, handle, etc. can be placed at the playing position.

<Example> Hereinafter, the embodiments shown in the drawings will be described. The present invention will be explained.

FIG. 1 is an explanatory cross-sectional view of a mold used in the manufacturing method of the present invention, which is a divided mold for bottle molding that opens and closes (
A vacuum hole (5) capable of holding a label (4) is provided in the cavity surface (3) of one of the molds (2) in 1), and communicates with the outside of the mold (2). A recess (8) is formed in the cavity surface (7) of the other mold (6), and this recess (8) is also provided with a vacuum hole (9), communicating with the outside of the mold (6).

In the manufacturing method of the present invention, from the open state of the mold (1) shown in FIG. Then, the label (4) is transferred to the cavity surface (3) of mold C) by each inserter (not shown) moving toward the cavity surface (3) and the cavity surface (7), and the label (4) is transferred to the cavity surface (3) of the mold C), and the label (4) is 2 is held on the cavity surface (3) by the suction force of the hole (5).
The handle member Qe is transferred to the recess (8) of the mold (6) and held by the suction force of the vacuum hole (9).

Next, as shown in Figure 2, the parison θD is inserted into the mold (
1), and mold the bottle (A) by normal blow molding (this mold is stretch blow molding using polyester resin, but this method can also be used for general blow molding). When the label (4) and the handle member O (D) are integrated and the mold (1) is opened, a bottle with a handle is obtained, as shown in FIG. can be obtained.

Here, FIGS. 4a and 4b show an embodiment of the handle member Qω, in which a fixing portion is attached and held in the recess (8) and is integrally bitten into the bottle of the handle member GO) by molding the bottle. In order for a part of the bottle to rotate to the back side of the surface, it is necessary to release the air inside the mold into the recess (8), and the fourth
It is preferable to provide a hole (B) in the column part 0 located on the back side of the fixing part Q31 in FIG. 4, and a hole in the fixing part Q31 in FIG.

In addition, as shown in Japanese Utility Model Application Publication No. 1-91744, instead of directly integrating the handle member into the bottle, two recesses are formed in the vertical direction, and the handle, which is a separate member, is later attached to the recess. By attaching and holding the connecting part member for the bottle, and holding the label in the opposing mold as in the first embodiment, the label and the connecting part member can be integrated at the same time as bottle molding. The invention has the above-mentioned configuration, and since it is only necessary to replace the mold, it is easy to attach the label to the front of the handle.
There is no need to make major line modifications like after-labeling, and even though the label is pasted on the opposite side of the handle, the label and handle or connecting part can be integrated at the same time as blow molding, and the label can be placed on the parting line. It has become possible to obtain a bottle with a handle that does not hang on the body. Therefore, when displayed at a store or used by a large number of people at parties, etc., the bottle can be used as a bottle with a label placed on the opposite side of the handle so that it can be viewed from multiple directions with a single label. Ta.
