Description

[Detailed Description of the Invention] The present invention relates to a blow molded product in which a pair of products are disposed opposite each other through a neck portion by blow molding.

Conventionally, this type of blow molded product requires post-processing to separate the product by cutting the end face of the neck portion. For example, when producing an armrest S for an automobile as shown in Fig. 1, a blow molded product is formed in which the armrest S is placed oppositely at the neck part K as shown in Fig. 2, and then the end face of the neck part (Fig. 2 and 3) are cut with a knife to separate each armrest S. However, the blow-molded product is supported during cutting of the end face of the neck part by locking claws N on both end faces of the neck part of the product as shown in Fig. 3, and the claws N are bent outward. Since both end faces are cut at the same time, it is necessary to cut both end faces at the same time. If they cannot be cut at the same time, the blow molded product will not be held and will move, and the end face of one of the uncut end faces will be cut. There was a drawback that it could not be cut. That is, this is due to the fact that the product is hollow due to blow molding and cannot support the neck itself.

Therefore, the present invention makes it possible to easily and reliably cut the end face of the neck by allowing the neck to be supported by itself.The details of the present invention will be explained below with reference to illustrated embodiments.

The armrest blow molded product E of this example shown in FIGS. 4 and 5 is manufactured by blow molding in the conventional manner.
2 are arranged opposite to each other, and an air blowing pipe section 3 is integrally molded on the outside of one neck section 1'. A distinctive feature of this example is that a supporting protrusion 4 is integrally provided on each neck portion for clamping and fixing with a fixing tool. That is, one neck part 1 has supporting protrusions 4 horizontally protruding from both the left and right sides thereof, and the other neck part 1' has supporting protrusions facing inward facing the air blowing pipe part 3. 4 protruding horizontally. The supporting protrusion 4 is located at the center of the neck portions 1, 1' and protrudes like a tongue along the parting line P.

Since the blow-molded product E of this example is constructed in this way, when cutting the neck end face 1a, first, as shown in FIG. The neck itself is held and fixed by pressure-clamping. Then, as in the conventional method, while pulling the end face 2a of the neck part of the product outward with a nail, the end face 1a of the neck part 1a of the product is cut with a knife to separate the parts 2 and 2. In this way, according to this example, the neck part is fixed by supporting the supporting protrusion 4, so that the end face 1a of the neck part can be easily cut, and even if the cutting of one side is delayed, the blow molded product remains immovable. Therefore, the other can be cut without any problem.

Although this example is configured as described above, the present invention is not limited thereto. For example, the shape of the support protrusion does not matter, and it may be a protrusion 6 in the form of a band provided around the outer periphery of the neck portion, as shown in FIGS. 6 and 7. In this case, as shown in FIG.
It is sufficient to hold the neck portion by engaging with the screws. Furthermore, the number of connection neck portions to be formed is not limited.
Further, the type and shape of the products are arbitrary, and any blow molded product may be used as long as a pair of products are disposed opposite each other through a neck portion.

In short, the present invention uses blow molding to connect a pair of products via a connecting neck.
For products that are separated by cutting the end face of the neck part, a supporting protrusion that can be held by a holder to fix the blow-molded product when separating and cutting the product is integrally molded in the center of the neck part. This is a blow molded product characterized by a protruding structure.

Therefore, according to the present invention, since the supporting protrusion is provided protruding from the neck part, the neck part is fixed by holding the protrusion with a fixture, so that the end face of the neck part can be cut stably and reliably. The effect is large.
