Abstract

A cap is to be removably attached to a cutting blade configured to cut a tape. The cap includes a grip portion to be gripped by a user and a holding portion configured to hold teeth provided on a distal end of the cutting blade while causing the teeth to face the grip portion.

First claim

The invention claimed is:

1. A cap which is configured to be removably attached to a cutting blade which cuts a tape, the cap comprising:
a grip portion to be gripped by a user; and
a holding portion configured to hold teeth provided on a cutting edge at a distal end of the cutting blade with the teeth of the cutting blade facing the grip portion;
wherein the holding portion comprises a protection portion including an end surface against which the teeth of the cutting blade are abutted when the cutting blade is in a loaded position in the cap, and
wherein the holding portion comprises a pair of side guide portions which are located on one end side of the grip portion and respectively correspond to side surface portions of the cutting blade, and the pair of side guide portions are configured to guide the side surface portions of the cutting blade when the cutting blade is mounted or removed.

2. The cap according to claim 1 , wherein the holding portion comprises a first support portion extending from a location on the one end side of the grip portion and between the pair of side guide portions, and the first support portion is configured to support a first surface of the cutting blade.

3. The cap according to claim 2 , wherein the first support portion further includes a positioning portion configured to be fitted into an aligning portion provided at a loading location on a binding machine for gardening upon loading of the cutting blade into the binding machine for gardening.

4. The cap according to claim 2 , wherein the holding portion comprises a second support portion extending from a location on the one end side of the grip portion and between the guide portions and configured to support a second surface of the cutting blade, and the second surface is on an opposite side of the cutting blade with respect to the first surface.

5. The cap according to claim 1 , comprising a positioning portion that is configured to align the cap and an aligning portion provided at a loading location on a binding machine for gardening, the positioning portion including a protrusion which protrudes in a direction away from the cutting blade when the cutting blade is in a loaded position in the cap.

6. The cap according to claim 1 , wherein a thickness of the end surface of the protection portion is configured to be thicker than a thickness of the cutting blade.

7. The cap according to claim 1 , wherein each of inner surfaces of the pair of side guide portions includes a flat surface and is configured to slidably support the respective side surface portions of the cutting blade when the cutting blade is mounted on or removed from the cap.

8. The cap according to claim 1 , wherein a length of each of the side guide portions is set to the distance between the distal end and substantially the middle of the cutting blade.

9. The cap according to claim 1 , wherein the grip portion includes a flat surface portion and a step extending around a perimeter of the flat surface portion;
the cap further including a first support portion located between the pair of side guide portions and which is configured to elastically urge against a first surface of the cutting blade at a location between the side surface portions of the cutting blade.

10. The cap according to claim 1 , wherein the cap is configured to receive the cutting blade in a mounting direction in which the teeth of the cutting blade are on a leading side of the blade with respect to the mounting direction and the side surface portions of the cutting blade are slidably guided by the pair of side guide portions; and
wherein the cap is configured such that in a loaded position of the blade in the cap, the teeth of the cutting blade are received in the cap and a mounting portion of the cutting blade at which the cutting blade is attached to a binding machine for gardening is exposed outside of the cap.

11. The cap according to claim 10 ,
the cap further including a first support portion located between the pair of side guide portions and which is configured to elastically urge against a first surface of the cutting blade at a location between the side surface portions of the cutting blade.

12. A cap unit, comprising:
a cutting blade configured to cut a tape, the cutting blade including a cutting edge on a distal end thereof; and
a cap removably attachable to the cutting blade, wherein
the cap comprises:
a grip portion to be gripped by a user; and
a holding portion configured to hold the cutting edge provided on the distal end of the cutting blade with the cutting edge facing a direction toward the grip portion;

wherein the holding portion includes a protection portion which receives the cutting edge with the cutting edge facing in the direction toward the grip portion,
wherein the blade includes a recess on an end opposite to the distal end at which the cutting edge is located,
the cap unit including a mounting direction in which the blade is loaded into the cap and an extracting direction in which the cutting blade is removed from the cap, and wherein the blade is moved from an unloaded position to a loaded position in the mounting direction with the cutting edge at a leading end of the cutting blade, and
in the loaded position in which the cutting blade is loaded into the cap, the recess of the cutting blade is exposed outside of the cap.

13. The cap unit according to claim 12 , wherein the cutting edge of the cutting blade includes a plurality of teeth, and wherein the teeth abut against the protection portion in the loaded position.

14. The cap unit according to claim 13 , wherein the protection portion includes tooth abutting portions and tooth fitting portions, with the tooth fitting portions protruding from the tooth abutting portions, and wherein when the cutting blade is in the loaded position the teeth of the cutting blade fit between the tooth fitting portions of the cap.

15. The cap unit according to claim 12 , wherein the cutting blade includes a pair of side surface portions extending between the distal end and the end opposite to the distal end; and
the cap includes a pair of side guide portions which slidably support the side surface portions of the cutting blade.

16. The cap unit according to claim 15 , wherein the cap further includes a first support portion which elastically urges against a first surface of the cutting blade at a location between the pair of side surface portions.

17. The cap unit according to claim 12 , wherein the grip portion of the cap includes a flat surface portion and a step extending around a perimeter of the flat surface portion.
