Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a handle for use in a double-walled container and a method for attaching the handle.

Conventionally, when attaching a handle to this type of container, the attachment part was either a single welded part, or it was attached directly to the double structure part, but when the former was used, the aesthetic appearance of the inner and outer walls of the attachment part was There you go,
In the latter case, the area around where it is attached becomes uneven and deformed depending on how tightly the rivet is tightened, and because the rivet is mounted on an unstable elastic part made of a hollow double wall, it cannot withstand long-term use. It was rattled.

On the other hand, there is Utility Model Publication No. 29-12509 which fixes a pin with a hanging step, which has an umbrella-shaped metal fitting at the intersection of two rods, presses the end of the pin, and fixes the two rods. One of the rods is loosely fitted so that the two rods can rotate relative to each other using the intersection as a fulcrum. Therefore,
Even if the end of the pin is fixed to one rod, the umbrella-shaped fitting on the head of the pin is not fixed to the other rod into which it is loosely fitted, so it can be used as is for fixing the handle of this type of container. I can't.

Here, when attaching a handle to a container with a double-walled structure, the inventor of the present invention has made various efforts to find a handle that is structurally strong and does not impair the aesthetic appearance. A handle for use in a double-layered container with a plurality of pins was discovered, and as a method for attaching it, the handle was attached to the outer and inner walls of the handle attachment part of the double-layered container by attaching a large step and a small part of the protruding pin of the handle made of plastic material. It has been found that it is sufficient to fit the stepped portions together and press the ends of the plurality of protruding pins by heating and melting them.

In the handle of the present invention, the large and small hanging steps of the protruding pin fit closely into the inner and outer walls of the double-walled container, and together with the provision of a plurality of protruding pins, the handle can be firmly attached and has an aesthetic appearance. There's nothing wrong with it. Note that an elegant shape can be easily formed by compressing the end of the protruding pin by heating it or by applying a rotating body to generate frictional heat.

The present invention will be explained in detail below with reference to drawings of embodiments.

The container shown in FIG. 1 consists of a container body 1 and a lid 2, and a handle 3 split in half is attached to the side near shoulders 1' and 2' of the container.

Handle 3 is the center line of half of container body 1 and lid 2
A large diameter hole 5 is formed in the upper surface of the outer wall 8 and a small diameter hole 6 is penetrated in a straight line in the upper surface of the inner wall 7 at positions slightly off to the left and right. Small step 9' of handle 3, large diameter 9, small diameter 1
Insert the two left and right protruding pins with 0 and abut the long metal plate 12 with the left and right holes 11 shown in Fig. 4 (it is possible without using the long plate), and insert the tip 10' of the protruding pin.
The rivet 13 is made to protrude and is pressed.
Reference numeral 14 denotes a fitting portion between the handle 3 which is split in half, the container body 1 and the lid 2. 15 is a hollow part, and 16 is a buckle that is fixed in the same way as a handle.

In addition, there is a concave-convex fitting 4 on X-X, and large and small diameter holes 9 and 10 are provided in the vicinity of this relatively thick and strong part, so the installation of the halved handle 3 is extremely strong. becomes.

The handle of the present invention is easy to integrally mold, and when attaching the handle of the present invention to a double-layered container, the protruding pin can be firmly fixed via large and small hanging steps, and there is no possibility of deformation due to over-tightening. It has various advantages such as the attachment part does not separate, and the installation work is extremely easy.
