Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a continuous package in which items to be packaged are enclosed at regular intervals in a long sheet-like packaging material, particularly a continuous package in which towels are sterilized after being wrapped. This invention relates to a device for taking out individual packaged items in an unsealed state.

BACKGROUND OF THE INVENTION When performing surgical or dental treatment or surgery, the operator always washes his hands before and after the treatment or surgery, and at that time, he uses a sterilized towel to prevent nosocomial infections. In addition, sterilized towels are often used to wipe off moisture after sterilizing and disinfecting treatment equipment and forceps, and to wipe off affected areas after treatment.

As a disposable towel for this purpose, it is soft and
The towels used are made of highly absorbent nonwoven fabric that does not generate dust, and are then sterilized using steam, ethylene oxide gas, or heat. When you pull out the first towel from the packaging material, the next towel can be removed.

The cards are taken out in order until the last one.

In a package in which towels are sealed and then sterilized, after the first towel is pulled out, the next towel may come into contact with the atmosphere in the room and become contaminated. Therefore, to prevent contamination, this package is stored in a box and the lid of the box is always closed, and the lid is opened only when necessary.
The conventional method is to take out the towels one by one. In this case, it is necessary to maintain the inside of the box in a sterile state, and several measures have been taken to achieve this.

For example, in order to prevent the inside of the box from momentarily becoming pressure-proof and sucking in outside air (indoor atmosphere) when the lid is opened and closed, the lid is designed to slide open and close to prevent the occurrence of turbulent flow.

An ultraviolet lamp is installed inside the box, and the lamp is turned on only when the lid is opened or closed, in order to maintain the inside of the box in a sterile state.

Further, the inside of the box is kept under a slightly pressurized condition to prevent the outside atmosphere from entering.

Problems to be Solved by the Invention However, it is not possible to simply make the lid of the box containing the sterilized package with towels slide open and close.
As the outside atmosphere gradually enters the inside of the box, the towels are inevitably contaminated.

Even with the method of installing an ultraviolet lamp inside the box, it is difficult to maintain sterilization for a long period of time.

Even with methods that keep the inside of the box under pressure, it is not possible to keep the inside of the box completely sterile, and if the inside of the box becomes pressurized even temporarily due to a power outage or other trouble, the towels will be contaminated and the contamination will be notified. may continue to use towels.

In addition, in any of the above methods, there is a problem in that the operation of taking out the towels from the box is not always easy.

The present invention maintains a completely sterile state at all times by enclosing an item to be packaged, such as a towel, in a long sheet-like packaging material at regular intervals and then sterilizing it, and automatically opens the towel only when it is used. The purpose is to provide a device that can be directly picked up.

Means for Solving the Problems The unsealing device for a continuous package of the present invention comprises a sheet (1) consisting of two long sheets (1A) and (1B) on the front and back sides.
