Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a jig used for forming vertical and horizontal scores of a pilfer-proof cap.

[Conventional technology]

Conventionally, vertical and horizontal scores are engraved on the peripheral wall of an aluminum cap, and when the cap is opened, these scores are cut off, making it possible to visually confirm whether or not the cap has already been opened. Pilfer-proof caps are widely used.

[Problem that the invention seeks to solve]

However, these conventional pilfer-proof caps have at least two problems.

One is that in the method of forming the vertical score from the outer surface of the cap peripheral wall, the vertical score is noticeable even before the cap is opened, and the difference from the cut vertical score after opening is not clear.
As a result, the effectiveness in preventing unauthorized opening was not satisfactory.

The other method is to form vertical scores from the inner surface of the peripheral wall of the cap when molding the cap using a press, and to carve horizontal scores in a subsequent process, in which the positional relationship between the vertical and horizontal scores is set constant. It is not possible, therefore, in this method.

Although the difference in the cut points before and after opening the vertical score is obvious, the parts cut by the horizontal and vertical scores become uneven after opening, resulting in large protrusions. It is dangerous as there is a risk of cutting your hand depending on the part.

The present invention was devised to solve these problems, and includes forming a vertical score on the inner surface of the peripheral wall of the cap, setting the positional relationship between the vertical score and the horizontal score, and cutting the vertical score when opening the cap. The aim is to set the cracks to the necessary extent.

[Means to solve the problem]

As a means for that purpose, the present invention provides a pedestal 1. Holder 2. Support 3. Storage body 4. and a carving blade 5.

The pedestal 1 was designed to be rotatable, and the cap 10 was placed upside down on its upper surface.

The holder 2 is located opposite the pedestal 1 and is movable up and down.

Top wall 11 of camp 10 lowered and placed on pedestal 1
is pressed onto the pedestal 1 to firmly hold the cap 10.

The support 3 had a holder 2 movable up and down in the center, and its outer diameter was set to be approximately equal to the inner diameter of the cap 10.

The storage body 4 stores and holds the support body 3, and forms a gap 16 with a distance approximately equal to the thickness of the peripheral wall 12 of the cap 10 between the skirt portion 6, which is the lower part, and the outer peripheral surface of the support body 3. .

A plurality of engraving blades 5 are installed along the circumferential direction of the support body 3, and the blade portions are made to protrude into the gap 16, so that the engraving blades 5 are installed along the circumferential direction of the support body 3, and the blade portions are made to protrude into the gap 16.
When it enters the gap 16, a vertical score 14 is formed on the inner surface of the nine peripheral wall 12.

Note that the holder 2 may be made rotatable so that the cap 10 can be installed at a set position necessary to form the vertical score 14 and the horizontal score 15 in a fixed positional relationship by rotating it while holding the cap IO. I can do it.

[Effect]

The operation of the pilfer-proof cap forming jig having the above configuration will be explained below.

First, before the vertical score 14 and the horizontal score 15 are formed, the camp 10 is placed on the pedestal 1 in an inverted position (
Figure 1). Next, the holder 2 descends and the cap top wall 11
Press down and firmly hold it on the pedestal l (Fig. 2).

After the cap 10 is fixed, the assembly of the storage body 4 and the support body 3 is lowered, and the cap peripheral wall 12 is inserted into the gap 16 formed between the storage body 4 and the support body 3, and the cap circumferential wall 12 is moved to the position. The engraving blade 5 forms a vertical score 14 on the inner surface of the peripheral wall 12 (FIG. 3).

After the vertical score 14 is carved, the storage body 4 and the support body 3 are
(Fig. 4), and a horizontal score 15 is formed by the cutting blade 17 installed in another device (Fig. 5). It is not necessary to raise the assembly immediately before forming the horizontal score 15, and it may remain in the lowered state.

When the formation of the horizontal score 15 is completed, the assembly of the storage body 4 and the support body 3 rises (Fig. 6), and the holder 2
also rises to release the hold on the pilfer-proof cap 13, which has a vertical score of 14 and a horizontal score of 15, completing the process (FIG. 7).

In order to form the vertical score 14 and the horizontal score 15 in a constant positional relationship, it is necessary to perform alignment before forming the horizontal score 15. or the fourth
It may be performed in the state shown in the figure, that is, after the vertical score 14 is formed. Furthermore, at this time.

Since the pedestal 1 is rotatable, it is rotated by the rotational force of the holder 2, making the above position setting possible.

Even after positioning the cap 10, the rotation of the camp 10 by the holding body 2 may be performed depending on the means for forming the horizontal score 15.
The vertical score 14 may be formed while constantly rotating.

〔Example〕

In the illustrated embodiment, the engraving blade 5 is disc-shaped.

It is of a roller-like rotating type that forms a vertical score 14 while rolling on the inner surface of the camp surrounding wall 12. This engraving blade 5 is
It is not limited to this rotary type; for example, it may be fixed immovably.

A cutout groove 9 is formed at the lower end of the outer circumferential surface of the support body 3, and this serves as a groove into which a blade is cut when forming the horizontal score 15 on the cap 10.

This cutout groove 9 allows the formation of a deep horizontal score 15.

The holder 2 here is composed of a rod piece 7 and a pressing piece 8, the outer diameter of the pressing piece 8 is made almost the same as the inner diameter of the cap 10, and by fitting into the cap 10,
It plays the role of positioning and fixing 0 at the set position.

In addition to the method described above, there are two methods for fixing the cap 10 at the set position.For example, a groove into which the cap 10 can be inserted is formed on the upper surface of the pedestal 1, and the cap 10 is pressed by the holder 2.
The purpose may be achieved by fitting the O into the groove and positioning it.

The number of vertical scores 14 and horizontal scores 15 and the positional relationship between the two scores are appropriately set depending on the size and material of the cap 100.

FIG. 8 shows a pilfer-proof cap 13 after forming vertical scores 14 and horizontal scores 15, with the number of horizontal scores 15 being twice the number of vertical scores 14, and the upper end of each vertical score 14 being centered on the horizontal scores 15. The positional relationship between the two is set so that they face each other.

〔Effect of the invention〕

In this way, when the pilfer-proof cap forming jig of the present invention is used, the vertical score can be formed on the inner surface of the cap peripheral wall, so the vertical score before opening is not noticeable, and the vertical score after opening is not noticeable. The difference between the scores becomes clear and this is highly effective in preventing unauthorized opening.

In addition, since the formation positional relationship of the vertical score and horizontal score can be set constant, depending on the formation positional relationship of the 9-car score as in the past, the cut point of the vertical score after opening is not noticeable and it is difficult to visually confirm. Moreover, on the contrary, the cutting part is not broken and protruded more than necessary, and the protruding part no longer cuts fingers, etc., and exhibits excellent effects.
