Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an opening opening device for a folding container, and more particularly, the present invention relates to a device for opening an opening of a folding container, which is formed by folding a paper sheet, and is capable of sufficiently opening the opening of the folding container and dripping fluid confectionery dough into the folding container. Relating to a container opening opening device.

Jelly confectionery is packaged and supplied to the market after molding the fluid confectionery dough. First, the inventor of the present invention used an automatic manufacturing device to make jelly confectionery by pressing the center part of a rectangular paper sheet with a push rod. We have developed a manufacturing device that presses downward and folds a paper sheet around this push rod to form a folded container, injects dough into the folded container, and simultaneously wraps it while forming the mold.

However, since this container is formed by folding a single sheet of paper, there is a problem in opening the opening of the container when filling the container with dough, making it extremely difficult to pour and fill the container with dough.

The present invention is based on the above points and in particular proposes an opening device with which the opening of a folding container from a paper sheet can be opened before filling with dough.

Embodiments of the present invention will be described below with reference to the drawings.

Note that FIG. 1 is a side view of an opening device according to one embodiment of the present invention, and FIGS. 2 and 3 are explanatory views of the operating mode of the opening device of FIG. 1, respectively.

First, in FIG. 1, reference numeral 1 indicates an endless orbit, and a receiver that moves intermittently along with this endless orbit 1 moves with a folding container 3 made of a paper sheet placed on a tray 2.

This folding container 3 is formed by pressing the center part of a rectangular paper sheet with a push rod and folding the other parts around the push rod, and is completely different from ordinary containers in that the folded part is opened. The paper sheet is then restored to its original rectangular shape, and will be simply referred to as a container hereinafter.

Next, when the container 3 reaches a predetermined location, a rod-shaped guide member 4 is placed on the endless track 1 so that it enters the container 3 when lowered from above.

That is, the rod-shaped guide member 4 is attached to the pedestal 5 by an elevating mechanism such as a cam so that it can be raised and lowered in the direction of arrow A-A in FIG.
Install so that it can slide freely according to the direction.

Further, while an annular stopper 7 is fixed to the lower end of the rod-shaped guide member 4, a part of the outer periphery of the sliding member 6 is enlarged to form a large diameter portion 8.
A plurality of connecting rods 10 are attached between the large diameter portion 8 and the stopper 7.

A bent portion 9a is formed in the middle of each connecting rod 10, and the portion 9 below the bent portion 9a of the connecting rod 10 is made of leather, synthetic resin, rubber, or other flexible material.

With the opening device having this configuration, even if the container is a folded paper sheet, the opening can be opened as follows.

First, the container 3, which is folded and formed from a paper sheet at another station, is conveyed intermittently into the tray 2 on the endless track 1, and stops at the position shown in FIG.

In this position, the rod-shaped guide member 4 is lowered and the lower end stop 7 hits the bottom of the container 3 (see FIG. 2).

In this state, the sliding member 6 slides downward along the rod-shaped guide member 4, and each connection frame 10 descends accordingly.

That is, in each connecting rod 10, the portion 9 below the bent portion 9a
Since it is made of a flexible material, only the lower part 9 is bent as shown in FIG. 3, and the opening of the container 3 is pushed open by the bent portion 9a.

Further, to explain in detail, the lower part 9 of each connecting rod 10 from the bending part 9a is made of other flexible materials such as leather, synthetic resin, rubber, etc., whereas the upper part is made of steel or other rigid material. As the sliding member 6 descends, each connecting rod 10 is bent at the bending part 9a, and the lower part 9 is curved from the bending part 9a, and the material of the container is not damaged by this curvature.
The opening is opened.

In summary, the present invention connects the sliding member that can be raised and lowered and the stopper at the lower end with a connecting rod, and each connecting rod is made of a rigid material and a flexible material, so that it can be easily accessed from the inside of the container. It can be expanded to

Claims (1)

[Claims] 1. Press the center part of a square paper sheet downward with a push rod, and fold the other parts of the paper sheet material other than the center part around the push rod so that the paper sheet material can be inserted into a folding container. The rod-shaped guide member is provided with a rod-shaped guide member that can be moved up and down, a sliding member that can be slid up and down along the rod-shaped guide member, and a stopper fixed to the lower end of the rod-shaped guide member. and the sliding member are connected by a plurality of connecting rods, each connecting rod has a bent part in the middle, and the lower part of the connecting rod from this bent part is made of leather or other flexible material. The downward sliding of the sliding member causes the flexible material portion at the bottom of each connecting rod to curve outward, and the upper part of each connecting rod expands toward the bottom to widen the container opening. A device for opening the opening of a folding container.
