Description

[Detailed description of the invention] The present invention relates to improvements in paper wrappers.

Conventional paper rolls have a cover with a blade at the tip that is supported by the paper itself, and when cutting the paper, pull out the required amount of paper and then hold the cover with the other hand while cutting. Therefore, the operation of cutting out the paper is troublesome, and it is extremely inconvenient not only for people who cannot use one hand, but also for those who have to use both hands at the same time in a place with strong shaking such as a toilet on a vehicle. It's even dangerous.

The present invention has been made to eliminate these conventional drawbacks, and has a simple structure that allows the necessary amount of paper to be easily cut out with one hand.

An embodiment of the present invention will be described with reference to the drawings. In FIGS. 1 and 2, 1 is a main body, 2 is a blade portion, 3 is a mandrel, 4 is a support portion, and 5 is a wrapping paper. The main body 1 is integrally formed with a back wall 11 and both side plates 12, and guides 6 are formed on opposing surfaces of the side plates 12 in a substantially S-shape and curved downward to gradually approach the back wall 11. It is formed of. A shaft 31 protrudes from both ends of the mandrel 3, and the shaft 31 rolls on the guide 6. The support portion 4 is formed into a convex curved surface so as to gradually approach the back wall 11 from the top to the bottom. 22 is a hand rod.

When the mandrel 3 is passed through the wrapping paper 5 and the shaft 31 of the mandrel 3 is placed on the guide 6, the outer peripheral surface of the wrapping paper 5 contacts the back wall 11 and the support part 4 at lines 50 and 52, respectively.
Moreover, the load of the mandrel 3 is applied to the guide 6 and the wrapping paper 5 in a distributed manner. Since the mandrel 3 is used to apply an appropriate load to the wrapping paper 5, a material with an appropriate specific gravity such as aluminum or plastic may be selected depending on the size of the mandrel 3.

When the outer diameter of the wrapping paper 5 decreases due to use, it moves diagonally downward, and the mandrel 3 also moves downward on the guide 6, and in the meantime, a diagonally downward force is always applied to the wrapping paper 5. Since the slope of the guide 6 is gradually approaching the vertical direction, the load applied to the wrapping paper 5 increases accordingly. Also rolling paper 5
The contact line between the outer circumference of the back wall 11 and the support portion 4 also moves from lines 50 and 52 to lines 51 and 53.

When cutting the paper 55, the paper 55 is pulled out to the upper right in FIG. 2 by a desired length, and then pulled downward to the right as shown, so that the blade 2 cuts the paper 55.

When the paper 55 is pulled upward and to the right, a frictional resistance corresponding to the weight of the wrapping paper 5 itself and the weight of the mandrel 3 is generated in the lines 50 and 52.
The weight of the mandrel 3 is selected so that 5 does not break.

Because of this frictional resistance, when the paper 55 is pulled diagonally downward, it can be cut by the blade portion 2 without slipping. Rolling paper 5 depending on use
The weight of the paper 55 gradually decreases, but the outer diameter also decreases accordingly, so the contact line moves from 52 to 53, and as a result, the paper 55
The area in contact with the surface becomes larger. Therefore, the contact resistance of the paper 55 increases by the increase in area, and a constant resistance occurs from beginning to end. That is, with this structure, a desired length of paper can be taken out by simply holding the end of the paper 55 with one hand and pulling it diagonally downward.

Note that the blade portion 2 may be set downward as shown by the imaginary line in FIG. 2, and the paper 55 may be cut by pulling it diagonally upward. Also guide 6
shows an example in which the slope is made to be S-shaped and gradually becomes steeper, but it is possible to keep the slope constant and increase the contact area of the paper 55 on the support part 4. The resistance during cutting may be made constant.

Further, although the guide 6 is used for rolling the mandrel 3, a guide 61 facing the guide 6 is formed as shown by the imaginary line in FIG. 1 in order to restrict unnecessary movement of the mandrel 3. It's okay.

As explained above, the present invention utilizes frictional resistance with the supporting part to always create a constant pull-out resistance on the paper to prevent the paper from slipping when cutting. It is very convenient because it can be cut into pieces, and the wrapping paper is easy to replace due to its simple structure.

In the embodiment, the case where toilet paper is used has been described, but it goes without saying that other wrapping paper can be used in the same manner.

Claims (1)

[Claims] 1 In a holder configured to rotatably hold the rolling paper between both side plates of the main body, a blade part and a support part are formed between the both side plates, a guide is formed on the opposing surfaces of the both side plates, and the rolling paper is held in a rotatable manner. A mandrel that penetrates the center hole and rotatably supports the wrapping paper is arranged along the guide, and the distance between the two is gradually increased downward so that the outer circumferential surface of the wrapping paper is always in contact with the supporting part and the rear wall of the main body. A paper wrapping machine characterized in that the supporting part is formed into a curved surface so that the support part becomes narrower, and the guide is formed so as to be inclined so that the mandrel moving along the support part always applies the weight of the mandrel to the wrapping paper.
