Blow molding forming bottle with handle and manufacturing device for the same

Abstract

The present invention relates to a blow-moulding formed bottle with handle and its production equipment. The mounting strength of said handle is raised, and sand handle is not easily separated from bottle body. It is characterized by that in the blow-moulding forming process two cylinders are respectively set, said two cylinders can be used for driving two cams, and said two cams can be used for forming upper and lower bottom side dishes, so that the action of the lower cam side is front and the action of the upper cam side is late, the dish depth and form of lower bottom side dish are identical to that of upper bottom side dish, the combination portions of said handle can be firmly combined in the above-mentioned upper and lower bottom side dishes, therefore the mounting strength of said handle can be raised, and said handle can not be easily separated from said bottle body.

Description

[0001] This application is a divisional application of the invention patent application submitted by Kaikai Co., Ltd. and Airtech ALT Co., Ltd., with the application number "200410045896.1" and the filing date of "May 25, 2004". technical field [0002] The present invention relates to a blow-molded bottle with a handle and a manufacturing device for the bottle. A bottom recess for attaching a handle is formed on the surface of the body portion, and a handle that is separately formed later is attached to the bottom recess. Background technique [0003] Blow-molded bottles are often used as liquid containers such as beverages represented by mineral water, edible fats and oils, and seasoning liquids. When such a bottle is more than 250ml and less than 1800ml, there are many examples where no handle is usually provided. However, when it is more than 1800ml, it is inconvenient to use if there is no handle, so there are many bottles with handles. [0004] In this bottle with a ...

Problems solved by technology

[0012] However, in the case of installing the support plate 108, although it is effective to prevent the handle 104 from coming out, when the use of the bottle is over and the bottle body 100 is separated from the handle 104, it is very troublesome to detach the support plate 108, which becomes a problem when separating. obstacle

[0013] In addition, in order to make the mounting state of the bottle body 100 and the handle 104 firm, it is conceivable to form the bottom side recesses 102, 103 deeper, or to shape the bottom side recesses 102, 103 The member called the cam is loaded into the metal mold, and the cam is opened at the same time during blow molding to form the bottom side concave parts 102, 103 that are concave up and down. For this reason, the concave parts of the bottom side concave parts 102, 103 There is a limit to the depth. In addition, as a major disadvantage, the depth and shape of the upper and lower bottom side recesses 102 and 103 are different from each other, which is also the reason why the handle 104 is easy to come out.
