Problems solved by technology

It is difficult to produce glass containers with special shapes and thick bottom walls with ordinary blow molding molds
[0012] That is to say, it is difficult to form a bottom with a specific shape and wall thickness at the bottom of the glass container due to the flow of molten glass using a common blow molding mold.

no. 1 Embodiment

[0044] 1st embodiment, such as figure 1 As shown, the bottom 18 and the bottom wall 17 of the glass container 10 in this example are very thick, and the bottom of the cavity is concave 19 .

[0045] Hereinafter, each main point will be described in detail by taking the example glass container of the first embodiment as an example.

[0046] 1. Glass container

[0047] (1) shape

[0048] The shape of the glass container is not particularly limited, and it may be a narrow-mouth bottle, a rectangular bottle, a barrel-shaped bottle, an oval-shaped bottle, or a special-shaped bottle according to the application.

[0049] The ideal shape is as figure 1 The narrow mouth bottle shown.

[0050] The narrow-mouth bottle 10 has a bottleneck 14 above, a body 16 in the middle, and a bottom 18 below. The bottle base 18 is formed by the bottle wall 17 and the recess 19 .

[0051] The height of the glass container (called A1) should be controlled within the range of 20~150mm.

no. 2 example

[0081] The second embodiment, as shown in FIG. 3, refers to a method of manufacturing a glass container with a low center of gravity and a concave bottom of the cavity. The blow molding die 43 is used together with the protruding bulkhead 20 to blow the molten glass 31 into a glass container.

[0082] Hereinafter, each main point of a manufacturing method is demonstrated in detail.

[0083] 1. Glass container

[0084] The detailed description has already been given in the first embodiment, so it will be omitted here.

[0085] 2. Blow molding mold

[0086] Containers produced by the blow molding method have high precision and high production efficiency. Mold As shown in Fig. 4 (a), (b), should use initial mold 43 and forming mold 103.

[0087] The blow molding mold is divided into the initial mold and the finished mold, which are introduced separately.

[0088] (1) initial model

[0089] The initial mold can be changed according to the specific shape of the glass containe...

Abstract

A glass container with lower gravitational center is made up by use of a blowing mould and a convex bulkhead. The finished glass container has thick and concave bottom.

Description

technical field [0001] The invention relates to a glass container, in particular to a glass container with a low center of gravity and a manufacturing method thereof. The present invention relates to the technique of increasing the thickness of the bottom wall of a glass container in order to make the glass container have a low center of gravity. Specifically, it is a glass container with a low center of gravity, the contents of which are easy to take out, easy to decorate, and will not tip over. It is this glass container and its highly efficient manufacturing method that are described in the present invention. Background technique [0002] Glass is widely used as a raw material for containers because of its stable chemical properties and good transparency. However, the bottom of the inner cavity of the general glass container is flat, and the thickness of the bottom wall is similar to that of the bottle body wall, and the problem of the center of gravity of the glass con...
