As shown in FIGS. 3 and 4, the pair of right and left magnets 41 attached to the distal end of the short arm portion 4b of the arm 4 abut from above when the door is closed. Unnecessary opening of the door 3 is prevented by the magnetic force acting between the iron plate 9 and the magnet 41 when the door is closed.

The material of the members constituting the dispenser 1 is not particularly limited, but it is preferable that at least a part of the material is transparent so that the inside can be seen. It is desirable to use a resin in which an ultraviolet absorber such as benzotriazole is blended, for example, in order to be able to transmit and reduce the amount of transmitted ultraviolet light.

Next, a method of using the dispenser 1 having the above configuration will be described below. When storing the roll R in the dispenser 1, the door 3 is tilted forward and downward with the shaft 5 as a fulcrum. Then, the door 3 is opened, the opening 2f is opened, and the long arm 4a of the arm 4 fixed to the door 3
Falls forward and downward, and the short arm portion 4b rises forward.

When the door 3 is opened, as shown in FIGS. 1 and 2, the roll R is placed on the stays 6a and 6b which are arranged side by side so that the axis thereof is parallel to the stays 6a and 6b. The roll R is supported from below by the stays 6a and 6b, and the end of the sterilized sheet S fed from the roll R is positioned on the mounting table 31. Then, in this state, when the door 3 is raised upward and backward with the shaft 5 as a fulcrum, the door 3 is closed and the opening 2f is closed, and the roll R is stored in the dispenser 1 as shown in FIGS. At the same time, the end of the sterilization sheet S is sandwiched between the mounting table 31 and the holding plate 8.

Further, with the closing of the opening 2f, the long arm 4a
Rises rearward, and the short arm 4b falls down rearward, so that the stays 7a and 7b are arranged in front and rear in place of the stays 6a and 6b. As a result, stay 6
The roll R supported by the rolls a and 6b is supported by the stays 7a and 7b from below when the door is closed.

When replacing the rolls R stored in the dispenser 1, when the door 3 is opened, the rolls R supported on the stays 7a, 7b become opposite to the stays 6a, 6b. It is pulled out together with the door 3 in a state of being supported upward. Then, this pulled out roll R
Then, a new roll R is placed on the stays 6a and 6b and the door 3 is closed according to the above procedure.

At the time of opening the door, the roll R is
a, 6b from below, and the door 3
However, as shown by an arrow A in FIG. 2, since the front end of the mounting table 31 and the floor F are inclined toward the shaft 5 due to contact, the door 3 is opened in a state where the roll R is stored in advance. Also, the roll R does not roll down from the door 3. When the roll R is stored in the dispenser 1 with the inclination of the door 3, the door 3
Is turned obliquely upward, thereby facilitating the storing operation. In addition, the roll R can be easily stored in the dispenser 1 by its own weight.

The sterilizing sheet S may be fed out from the upper side of the roll R as shown in the figure, or may be fed out from the lower side of the roll R. When the indications are printed, it is desirable to extend the indications from the upper side so that these indications can be visually recognized.

When removing the sterile sheet S from the dispenser 1, the end of the sterile sheet S sandwiched between the mounting table 31 and the holding plate 8 is pulled out forward. Then, the roll R supported from below by the stays 7a and 7b rotates, and the sterilization sheet S is fed forward from the dispenser 1. Here, as described above, the stays 6a, 6b, 7
a, 7b are composed of a shaft extending left and right and a roller rotatably mounted around the shaft,
The rollers rotate together with the rotation of the roll R supported by the rolls a and 7b. As a result, the rotation of the roll R is performed smoothly, and the force for pulling the sterilization sheet S forward can be reduced.
The rotating roll R and the stays 6a, 6b, 7a, 7
The surface of the sterilizing sheet S is not scratched by sliding with b.

Then, when the sterilized sheet S having a desired length is fed out, the mounting table 3 is cut using a cutting means such as a cutter.
1. Cut the upper sterilization sheet S left and right. In this case, since the sterilizing sheet 5 is urged toward the mounting table 31 by the weight of the holding plate 8 and the action of the spring 82, when the sterilizing sheet S is cut, the sterilizing sheet S on the mounting table 31 is removed from the cutting means. There is no slippage between the mounting table 31 and the holding plate 8 due to the applied force. Therefore, displacement of the sterilization sheet S during cutting is prevented, and as a result, the sterilization sheet S can be cut easily and accurately without particularly supporting by hand. Further, the cutting means is fitted into a guide groove 31a formed on the upper surface of the mounting table 31, and the guide groove 3a
By cutting along the line 1a, the sterilization sheet S can be accurately cut into a desired shape (for example, a straight line) along the extending direction of the guide groove 31a. Further, since the sterilizing sheet S is sandwiched between the mounting table 31 and the holding plate 8, the sterilizing sheet S fed out onto the mounting table 31 is prevented from rewinding into the main body 2.

According to the dispenser 1 having the above configuration, since the roll R is isolated from the outside by the main body 2 and the door 3, paper dust derived from the paper box in which the roll R is packaged,
Alternatively, dust and bacteria in the air are prevented from adhering to the roll R, and a clean sterile sheet S can be used at all times.

Further, the roll R is placed on the stays 6a and 6b, the end of the sterilized sheet S fed from the roll R is positioned on the placing table 31, and the door 3 is closed. 1 and the end of the sterilization sheet S is sandwiched between the mounting table 31 and the holding plate 8 (removable state). Also, when removing the sterilization sheet S from the dispenser 1, it is only necessary to pull out the end of the sterilization sheet S sandwiched between the mounting table 31 and the holding plate 8, and the sterilization sheet S can be removed from the mounting table 31. Because it is sandwiched between the holding plate 8
Cutting of the sterilization sheet S is also easy. That is, according to the dispenser 1, the operation required for storing the roll R in the dispenser 1, taking out the sterilized sheet S from the dispenser 1, and further cutting the sterilized sheet S taken out can be greatly simplified. .

Further, since the dispenser 1 is made of a material that transmits visible light and reduces the transmission of ultraviolet light, the remaining amount of the sterile sheet S stored in the dispenser 1 is visually observed from outside the dispenser 1. , And the sterilization indicator or the like printed on the sterilization sheet S is not discolored by ultraviolet light in the outside air. Furthermore, since the rolls R are not stored in the paper box and used, but stored in the dispenser 1, the packaging of each roll R is made of an inexpensive material such as a resin film instead of an expensive paper box. There is also an effect that it can be used.

The specific shape and the like of each member constituting the dispenser 1 are, for example, the width and diameter of the roll R to be stored, the material and shape of the sterilizing sheet S (a flat bag or a gusset bag), or the use of the dispenser 1. Needless to say, it can be arbitrarily changed according to the environment and the like without departing from the gist of the present invention.

For example, in this embodiment, the stays 6a, 6
Each of b, 7a, 7b is composed of a shaft extending left and right and a roller rotatably mounted on this shaft. The rotating roll R supported by the stays 7a, 7b from below is not necessarily a stay. It is not necessary to be in contact with 6a, 6b. Therefore, in such a case, it is not necessary to provide rotatable rollers or the like on the stays 6a and 6b.

As the cutting means, not only the above-mentioned manual cutter but also a cutter which automatically travels along the guide groove 31a to perform cutting automatically may be used. Further, the material that transmits visible light and reduces transmission of ultraviolet light does not necessarily need to be used for the entire dispenser 1, as long as the roll R housed in the main body 2 is used at least in a position where it can be viewed. You can reach its purpose.

[0032]

As described above, according to the dispenser for sterilizing sheet according to the present invention, adhesion of paper dust derived from the paper box in which the roll is packaged, or dust and bacteria in the air to the roll is prevented. Thus, a clean sterile sheet can always be used. Also, storing the roll in the dispenser and taking out the sterile sheet from the dispenser,
Further, the operation required for cutting the sterilized sheet taken out is also simplified.
