題があった。[Problem to be solved by the invention] By the way, in a container consisting of a container body and a lid that can be freely flashed, it is possible to attach the plate piece that connects the container body to either the body or the lid. Molding it in one piece is better in terms of reducing the number of assembly steps and simplifying the configuration. However, as described in the above-mentioned Japanese Utility Model Publication No. 61-45315, in this type of container, the plate piece is also blow-molded integrally with the container body, so the pin of the plate piece is hollow and Only short pieces can be obtained, and as a result, the strength of the plate to attach the container body and lid is low, and there may also be restrictions on the attachment of the plate with pins, so it is widely used in various containers. The problem was that I couldn't do it.

That is, the molten parison is placed between the split molds, the split molds are closed, the parison is closed, and blow molding is performed, whereby the plate piece with the mounting pin protruding is attached to the container member body through the hinge part. In the method of manufacturing a container member integrally formed with a mold, in the process of closing the split mold, the outer circumference surrounding the compression surface on which the plate piece is molded is first compressed, and then the compression force of the compression surface is increased. A plate piece of the required thickness is molded, and as the resin pressure increases as the compression force on the compressed surface increases, the resin enters and fills the pin forming hole formed on the compressed surface, and solid pins are formed on the plate piece. A method of manufacturing a container member is characterized in that:

を構成するものである。First, the molten parison 8 is placed between the open split molds 1.1 (FIG. 1), and then the split molds 1.1 are closed (FIG. 2). In the process of closing the split molds 1.1, , the plate piece 11 of the parison 8 is compression-molded on the compression surface 5.5, but prior to this, the outer periphery of the plate piece 11 is compressed by the compression part 7 surrounding the compression surface 5 to form the plate piece 11. This results in a state in which outward movement of the resin is suppressed. Therefore, the resin forming the plate piece 11 compressed by the compression surfaces 5, 5 reliably enters and fills the pin forming hole 6 as the compression force increases, so that it is solid and has the required length. A pin 12 is formed. The hinge portion 9 that connects the main body 10 of the container 11 and the plate piece 1 is formed by compressing and thinning a portion of the compressed portion 7. In addition, the compression part 7 is configured to be slidable within the mold, as shown in FIGS. 2 and 3, and the protrusion movement of the compression part 7 is prevented in the process from FIG. By performing this prior to the closing movement of the mold, it is possible to further prevent the resin from moving outward. Container member body IO
is r of split mold 1.1? Blow molding is performed by blowing compressed air into the parison B after the iron chain 9 After the molding is completed, if the molded product is taken out from the split molds 1 and 1, the shape shown in Fig. 4 will be obtained, so the burr 15 By removing , a container member in which the container member main body lO and the plate piece 11 are integrally formed via the hinge portion 9 can be obtained.The container member illustrated in the second manufacturing process is shown in FIG. As shown, the main body of the case is composed of the main body 16 and the lid 17.

Lid body 17 with pin holes 19 drilled in advance on the bottom
In the upright position a, insert the pin 12 into the pin hole 19 of the lid 17.
eMating. First, the tip #IIm of the pin 12 is pressed and crushed using the pressing tool 2o to form the head 21 on the pin 12 and fix the plate piece 11. In addition, the pressing tool 2
0 is one that performs staking by heating, but it may also be one that pressurizes m.
According to the No. 1 manufacturing method, when blow molding a container member, the compressed surface 5 for molding the plate piece 11 is formed by using the split mold Ll in a pinwheel process.
, 5 is compressed in advance by the compression section 7, and
The compression force of the compression surfaces 5, 5 is increased to obtain the required thickness of the plate piece I.
Since t is a molding gap, as the compression force of the compression surfaces 5 increases, the resin at that portion is prevented from moving to the surroundings. Therefore, the resin reliably enters and fills the pin forming holes 6 formed in the compression surfaces 5, 5, and a solid pin 12 of a required length is formed in the plate piece 11.

成することができる効果が得られる。[Effects of the Invention] The method for manufacturing a container member according to the present invention places a molten parison between split molds, closes the parison through the split molds, and performs blow molding. , in a method for manufacturing a container member in which plate pieces from which mounting pins protrude are integrally formed via a hinge part, in which the outer periphery surrounding the compressed surface on which the plate pieces are formed is formed in a split mold in the dark. The compressive force of the compressed image is then increased to form a plate piece of the required thickness, and the pins formed on the compressed surface are I in the molding hole! #Since the resin is introduced and filled to form a solid pin in the plate piece, it is compressed on the compressed surface. This provides the advantage of being able to form a solid pin of the required length on the piece.

In a method for manufacturing a container member integrally formed via a hinge part, in the process of closing a split mold, the outer peripheral part surrounding the compression surface on which the plate piece is molded is first compressed, and then the compression force of the compression surface is reduced. is raised to form a plate piece of the required thickness, and as the resin pressure increases with the increase in compression force on the compression surface, resin enters and fills the pin forming hole formed on the compression surface, and the plate piece is filled with resin. A method for manufacturing a container member, comprising forming a pin in an actual state.
