In a container (1) containing an eye drop and consisting of a body (1a) with an outlet at the top and a cap (1b) coupled to the outlet side, a label is attached in a form surrounding the body (1a) and the cap (1b) ( As a manufacturing method for 2),

It largely consists of a label production stage, a printing stage, a cutting line formation stage, and an adhesive application stage.

Looking at each step,

The label production step is

As shown in Figures 1 and 12,

Forming a first vertical cut line (2d) starting from one end of the grip portion (2b) in the wrapping portion (2a) of the label (2) and extending vertically to an area adjacent to the horizontal cut line (2c);

It is formed on one end of the wrapping part (2a) of the label (2), and when attached to the container (1), one end and the other end of the wrapping part (2a) overlap each other and correspond to the first vertical cutting line (2d). Step of forming a second vertical cutting line (2e) in a shape running vertically in the area.

It consists of

Ultimately, as shown in FIG. 3, when the grip portion 2b is held and pulled downward, it is cut along the first and second vertical cut lines 2d and 2e, and when pulled to the left, the horizontal cut line 2c is cut. By cutting along, only a part of the label 2 remains on the body 1a of the container 1 and is removed.

The adhesive application step is

As shown in Figures 2 and 12,

Starting with a first area including the horizontal cutting line 2c on the back side of the wrapping part 2a of the label 2, and the right end of the first area on the back side of the wrapping part 2a of the label 2. An adhesive ( This is the step of applying 2f).

The label (2) composed of the above configuration uses shrink film as a raw material. Since the existing PVC shrink film can cause environmental pollution, the label (2) in the present invention uses a shrink film made of OPS (Oriented Poly styrene). use.

This OPS shrink film has excellent advertising effectiveness as it allows labels to be attached to the entire container. It can also adhere to curved surfaces, has excellent printing effects, and is very convenient to use as the labels do not easily fall off during distribution.

In addition, OPS shrink film can reduce costs by about 10 to 20% compared to shrink films such as PET, and because it uses alcohol-based solvents that are harmless to the human body, the label surface is safe for the human body and the printing site can be kept comfortable, and when separating labels, When placed in water in a water tank along with a container, it floats on the water due to the difference in specific gravity from the container, making it easy to separate and remove. When shrinking in a highly curved area, the film shrinks cleanly without curling or wrinkling.
