ンが脱落することがある。(Problems to be Solved by the Invention) However, in the former case, labor for applying an adhesive to the packing or the packing groove is required, and the work is troublesome, and a problem such as detachment of the packing due to poor bonding occurs. Also in the latter case, the packing material may not come off due to insufficient adhesion because the material of the box-shaped body and the packing material to be injection molded are not chemically bonded.

付の作業性を著しく阻害する。Dropping of these packings occurs during transportation, resulting in defective products. In addition, when assembling the box-shaped body, it is often installed with the opening end facing downward, so that the box-shaped body falls off during the assembling work and significantly impairs the workability of assembling.

In this case, the packing is made of a soft synthetic resin integrally molded.

形作業も容易である。(Operation) In the box-like body with packing of the present invention, the packing is filled in the packing groove and the packing material is also integrally filled in the lateral hole, so that the packing has the same shape as the packing groove and is compressed. The force acting in each direction at the time becomes uniform, and even if the adhesion force to the packing groove is loosened, it is locked and held by the plurality of lateral holes and does not fall off. In addition, the packing is formed by injection molding or injection molding the packing material into the packing groove.In this case, since the horizontal hole acts as a gas vent hole, the packing shape becomes complete, and the molding work is also completed. Easy.

形されたパッキンの突出部4aが充填されている。(Embodiment) The box-like body 1 with packing shown in FIG. 1 is an ornament of an internal combustion engine, and a packing groove 3 provided at an open end of a box-like body 2 is filled with a packing 4 of a soft synthetic resin. . The packing groove 3 is formed by the inner side wall 5 and the outer side wall 6. A plurality of lateral holes 7 are formed at appropriate intervals through the outer side wall 6, and are filled with a projecting portion 4 a of the packing integrally molded with the packing 4.

化しパッキンが成形される。The box-shaped body 2 is formed of a synthetic resin in advance, and when a synthetic resin material serving as a soft elastic packing is injected into the packing groove 3 or a foamable synthetic resin material is injected, the box groove 2 is inserted into the packing groove 3 and the lateral hole 7. The synthetic resin material is fed.
At this time, the air in the packing groove and the generated gas are released from the lateral holes without being confined in the groove, and the material is solidified to form the packing.
尚この箱状体はオーナメントに限られずロッカーカバ
ーその他容器の蓋などに広く適用できる。In addition, this box-shaped body can be widely applied not only to ornaments but also to rocker covers and lids of containers.

Are integrally filled, so that the packing having the same shape as the packing groove is formed, the forces acting in each direction when the box-shaped body is mounted are uniform, and therefore, the sealing performance is excellent, and the packing groove inner wall Even if the degree of adhesion with the seal is reduced, the packing does not fall off, and there is no occurrence of a defective packing missing or a drop in workability due to falling off during assembly. In addition, since the horizontal hole serves as a gas vent hole, packing can be easily performed, and a defective packing shape due to gas retention does not occur.
