Description

[Detailed description of the device]

[0001]

[Industrial application] The present invention is mainly used for packaging and selling circular saws (hereinafter simply referred to as circular saws) such as tip saws for brush cutters, and is also used by consumers of purchased items as cases for storage. It is a device for a circular saw case to be obtained.

[0002]

2. Description of the Related Art Conventionally, in order to wrap a circular saw, the circular saw is simply put in a rectangular plastic bag or a paper bag as it is. At that time, in order to protect each blade of the circular saw, a thin vinyl tube is axially incised and fitted into the peripheral edge of the circular saw. Also, instead of a bag, it is also stored in a square case made of cardboard. An example of a case using cardboard is shown in FIG. This case B
For example, folding pieces C, C, D and E which can be folded inward are provided on four sides of a square cardboard, and a circular saw is placed on the folding pieces C on the left and right sides. , C are bent inward, then the upper and lower bent pieces D and E are bent inward, and the end of the upper bent piece D is inserted into the elongated hole F formed in the lower bent piece E. The tongue piece G that is protruded in is inserted and locked.

[Problems to be Solved by the Invention] When the circular saw is stored in a plastic bag, a paper bag, or a cardboard case as it is, the bag or case is damaged during transportation and the cutting edge is exposed. It often happens. In that case, not only is it dangerous, but it may damage the cutting edge. In particular, brazing of a super hard tip, which is a hard material, has a drawback that the tip is easily chipped.

On the other hand, in a case where a protective material such as a vinyl tube is attached to the periphery of the circular saw so as to cover each blade of the circular saw, the blade can be protected, but it takes a lot of time to attach the protective material. The cost was high.

The present invention solves the above-mentioned drawbacks of the prior art, the blade of the circular saw is not exposed, the entire circular saw is protected, and the circular saw is easily packaged and stored. The purpose is to provide a case for a circular saw.

[0006]

[Means for Solving the Problems] A base paper for forming a case is folded in two, and one is used as a cover plate 2 and the other is used as a substrate 3 via a folded portion 1. On the substrate 3, a holding member 8 made of a material that is roughly equivalent to the thickness of a saw and can be bitten into the blade of a circular saw, such as corrugated cardboard or foamed synthetic resin, is mounted. A recess 7 which is slightly smaller than the diameter of the circular saw to the cutting edge is formed so that the circular saw is accommodated therein.

In order to provide the saw case more easily, the whole case is made of corrugated cardboard, and the folding pieces 4, 5 and 6 are formed on three sides except the folding portion 1 of the portion which becomes the substrate 3. Then, this is folded back and adhered to the substrate 3, and the recess 7 is formed by the combination of the tip end shapes of the three folded back pieces 4, 5, 6.

[0008]

When the circular saw, which is the contained article, is to be stored in the recess 7, the blade edge of the circular saw is caught on the inner peripheral edge of the recess 7. When forced in this state, the cutting edge of the circular saw bites into the inner peripheral surface 8a of the holding member 8. As a result, the circular saw is securely held in the case when the cover plate 2 is put on the circular saw without being supported by the inner peripheral surface 8a of the holding member 8 and moving in the recess 7. At this time, the blade edge of the circular saw bites into the inner peripheral surface 8a of the holding member 8 and is not exposed to the outside of the case.

[0009]

Embodiments of the present invention will be described with reference to the accompanying drawings.

1 to 2 show a first embodiment of the present invention, and FIG. 3 shows a second embodiment. In the embodiment shown in FIGS. 1 and 2, a rectangular corrugated cardboard having a dimensional ratio of 1 to 2 is folded in two at the center position, and one of them is a cover plate 2 and the other is a substrate 3 via the folded portion 1. A circular saw A can be fitted when the inward folding sides 4, 5 and 6 are formed on three sides of the square substrate 3 and are folded and adhered onto the substrate 3. The recess 7 is formed.

Explaining this case in more detail, as shown in FIG. 2, the edges of the folding pieces 4, 5, 6 provided on the substrate 3 form an inner diameter slightly smaller than the outer diameter of the circular saw. Therefore, each is cut into an arc shape and attached to the substrate 3 to form a holding member 8 having a circular cut portion formed in the center thereof, and the circular cut portion serves as a recess for accommodating a circular saw.

When a circular saw is fitted into the circular recess 7, one plate surface abuts on the substrate 3 and the hole diameter of the holding member 8 is slightly smaller than the outer diameter of the circular saw. The cutting edge of the saw bites into the inner peripheral surface 8 a of the holding member 8. As a result, the circular saw is supported by the inner peripheral surface 8a of the holding member 8. Further, the dimension from the inner peripheral surface 8a to the outer surface of the holding member 8 is large, and there is no possibility that the blade edge of the circular saw will break through the case and be exposed to the outside of the device. To wrap the circular saw, the holding member 8 holds the circular saw, and then the cover plate 2 is folded and fixed. At this time, the entire circular saw is firmly held in the case, and not only the blade edge but also the board surface is protected by the substrate 3 and the cover plate 2.

The outer shape of this case is not limited to a square as in the illustrated embodiment, but a rectangular, polygonal, circular or other recess is formed in the center thereof to accommodate a circular circular saw. In addition, any shape may be used as long as it is folded in half.

A second embodiment shown in FIG. 3 is an embodiment in which a holding member 8 which is a separate body from the substrate and the cover plate is attached to the inner surface of the substrate 3, and the holding member 8 has an object to be packaged. A circular hole, which is slightly smaller than the outer diameter of the circular saw that is the container, is formed. The holding member 8 to be attached to the substrate 3 is made of corrugated paper,
It is possible to use a foamed synthetic resin material such as polystyrene foam on a plate, which has strength such that the blade edge of a circular saw easily bites and does not easily lose its shape. Further, the hole formed in the holding member 8 may be a quadrangle or a polygon other than the circular shape, but a circular shape is preferable.

By the way, as shown in FIG. 2 and FIG.
In the recess 7 of the holding member 8, a part of the folded portion 1 side is opened so that the blade edge of the circular saw can be easily taken in and out by fingers.

In order to make the cover plate 2 of the case openable and closable and to prevent the stored circular saw from rattling, the sheet fasteners 9b and 10b are fixed to a part of the cover plate 2 and Planar fasteners 9a and 10a paired with the planar fasteners 9b and 10b are provided on the opposing substrate side. At this time,
The planar fasteners 9a and 10a on the substrate side are fixed to the substrate, the holding member 8 is provided with a window hole, and the planar fasteners 9b and 10b of the cover plate 2 are projected. As a result, the sheet fastener 9 is attached in a state where the inner surface of the lid plate and the surface of the holding member are in close contact with each other.
A and 9b and 10a and 10b can be attached and covered.

[0017]

According to the invention as set forth in claim 1, the inner peripheral surface of the holding member engages with and supports each blade edge of the circular saw, so that the circular saw does not rattle or move in the recess. It can be securely held, and the cutting edge of the circular saw is not exposed outside the case, so it is safe.
Moreover, there is an effect that the cutting edge is not damaged. Further, the circular saw case of the present invention holds the entire circular saw in the case, and since both front and back surfaces are covered with the substrate and the cover plate, not only the blade but also the board surface is protected.

According to the second aspect of the invention, since it is an assembling type using corrugated cardboard that is cut integrally, it is easy to manufacture and can be supplied at a low cost.
