  In FIG. 3A, which shows a cross-sectional view of the present invention as a whole, as a preferable example, for example, a cylindrical flexible case 1 formed of a thin resin is provided with an adhesive roller 2 stored (inserted). ) Or can be pulled out (removed).

  Hereinafter, based on each figure, a preferable example of the case 1 and the adhesive roller 2 will be described.

  The case 1 has an opening 100 on one side 1a (one side) and a bottom portion 101 on the other side 1b (the other side), and receiving means A is provided on the bottom portion 101. In the example shown in FIG. 3A, the receiving means A is a cylindrical body 3 made of a finger-sack-shaped flexible member erected on the bottom 101, and is attached to the top 3 a of the cylindrical body 3. A hole 300 is formed in the direction. Moreover, as for the cylinder 3, the top part 3a and / or the vicinity part 3b are circular arc shape, and the main-body part 3c and the base end part 3d are made into cylindrical shape. Although not shown, a thin structure may be sequentially formed from the base end portion 3d toward the top portion 3a in order to ensure elasticity and / or strength. In another example shown in FIG. 6, the structure is integrated with the bottom 101. For example, an opening 301 provided on the bottom 101 (not shown) is used as a core insertion space (not shown). In another example, the case 1 and the cylinder 3 can be formed in one step. An annular gap 5 is formed between the outer surface of the main body 3 c of the cylindrical body 3 and the inner surface 1 c of the case 1. The structure of the cylinder 3 is one of the points of the present invention.

  In the opening 100 of the case 1, one or several locking notches B to which the handle 200 of the adhesive roller 2 is locked are formed. The locking notch B includes an insertion portion 6 at the end of the opening 100 and a locking guide groove 600 having an elongated groove shape formed from the end of the opening 100 toward the bottom 101 of the case 1 (the outer diameter of the handle 200). And a bulge-shaped locking key portion 601 formed at the base end of the locking guide groove 600 (which has a hole having substantially the same diameter as the outer diameter of the handle 200). Is inserted into the locking guide groove 600 from the insertion portion 6 and moved toward the locking key portion 601 while expanding the diameter of the locking guide groove 600 (so-called expanding by narrowing the narrow width). When the locking key portion 601 is reached, the handle 200 is accommodated in the locking key portion 601 and the locking guide groove 600 whose diameter has been enlarged returns and is reduced in diameter (becomes narrower). The structure is to be eliminated. That is, this is a structure in which the lock function works. In addition, when the locking key portion 601 is reached, a clicking sound is generated between the material of the case 1 and the metal material of the handle 200, so that the locked state can be confirmed, and I can rest assured. Note that the inlet side of the locking guide groove 600 is not shown, but may have an expanded shape. Moreover, the case 1 can avoid contact with the adhesive surface of an adhesive roller, which will be described later, by adopting a structure in which the case 1 is not recessed when grasped by a hand.

  The adhesive roller 2 is composed of a main body 2a and an adhesive tape cylinder 2b that can be attached to and detached from the main body 2a. The adhesive tape cylinder 2b is attached to and detached from a cylindrical outer peripheral surface of a reel of the main body 2a described later. It is provided freely. The main body 2a includes a handle 200 having an approximately L shape, a reel 201 having recesses 201a and 201b at both ends provided at a base end portion 200a of the handle 200, and a shaft portion provided at a free end of the reel 201. 202 and a grip 203 provided at the free end 200b of the handle 200. The adhesive tape cylinder 2b includes a cylindrical paper tube 205, an adhesive tape 206 having an adhesive surface 206a connected to and laminated on the outer periphery of the paper tube 205, and an adhesive tape 206 provided at appropriate intervals. And a perforation 207 for cutting. Note that the adhesive-free tape 206 is provided with an adhesive-free portion 206b at both ends (both ends have a structure without the adhesive surface 206a). This structure without the adhesive surfaces 206a at both ends is to prevent adhesion of glue to the separation protrusion (described later), the inner surface 1c of the case 1, the bottom surface 101 of the case 1, or the like. Furthermore, the structure without the adhesive surfaces 206a at both ends facilitates peeling and simplification of the adhesive tape 206, or avoids glue sagging.

  An example of the relationship between the pressure-sensitive adhesive tape cylinder 2b and the pressure-sensitive adhesive tape 206 will be described. When the pressure-sensitive adhesive tape 206 of the pressure-sensitive adhesive tape cylinder 2b runs out, the pressure-sensitive adhesive tape cylinder 2b is pulled out from the reel 201 of the main body 2a, and the pressure-sensitive adhesive tape cylinder 2b. When the reel 201 is removed, the reel 201 becomes empty. By inserting and setting a new adhesive tape cylinder 2b on the reel 201, the adhesive roller 2 can be used.

  A spacing means C is provided on the inner surface 1c of the opening 100 of the case 1 and there are examples shown in FIGS. 7-1 to 7-4. For example, in FIG. 7-1, the protruding protrusions 10 having an elliptical bulge shape provided at intervals are separated from each other by an adhesive-free portion 206 b, and the inner surface 1 c of the case 1 and the adhesive surface of the adhesive tape cylinder 2 b. It is intended to avoid contact with 206a and avoid deterioration of the adhesive effect of the adhesive surface 206a. 7-2, the ring-shaped and spaced-apart chevron-shaped spacing protrusion 10 is shown in FIG. 7-3, the intermittent-type and the chevron-shaped separating protrusion 10 is further cut off in FIG. The formula and the drop-shaped separating protrusion 10 are shown respectively. In any case, the shape having a small contact area is intended to avoid contact with the adhesive surface 206a when the adhesive roller 2b is inserted (inserted) or pulled out, and to eliminate adhesion of glue. This structure is one of the points of the present invention. And this separation protrusion 10 has the characteristic which can avoid a contact with the adhesive surface 206a of the adhesive tape 206 by making the opening side into the slope shape 10a. Further, each structure of the separation protrusion 10 serves as reinforcement (prevention of depression) of the case 1 including the opening 100, and contributes to thinning of the case 1, and to the adhesive surface 206a of the adhesive roller 206 described above. Can be avoided. In order to avoid contact with the adhesive surface 206a of the adhesive tape 206, the opening 100 is configured to be provided with an expanding slope 100a that is thinned toward the opening 100.

  Next, an example of putting the adhesive roller 2 in and out of the case 1 will be described. From the opening 100 of the case 1, the main body 22a of the adhesive roller 2 and the adhesive roller 2 are inserted from the left side in FIG. At that time, the insertion operation is performed so that the adhesive surface 206a on the insertion side (left side in the direction) of the adhesive tape cylinder 2b does not contact the separation protrusion 10. Then, when the shaft portion 202 of the main body 2a is inserted into (inserted into) the hole 300 of the cylindrical body 3 provided in the bottom 101 of the case 1, and the insertion is completed (stored), the cylindrical body. 3 is provided with a recess 201b of the reel 201 with an interval Y (the interval Y can be eliminated. In the absence of the interval Y, the adhesive tape cylinder 2b can be inserted smoothly, or The adhesive tape cylinder 2b is supported so as to be parallel to the inner surface 1c of the case 1). Further, in the process of this insertion, the handle 200 enters the locking notch B, and when the insertion is completed, the handle 200 clicks into the locking key portion 601 and is inserted. Recognize safety and operational reliability. Also, the structure in which the adhesive tape cylinder 2b does not come into contact with the bottom 101 of the case 1 is ideal, and the tip of the shaft part 202 makes contact with the bottom 101 or makes contact with the bottom (not indicated) of the cylinder 3. And adopt a structure to stop. Furthermore, depending on the tightening (clamping) state between the handle 200 and the locking key portion 601 during storage, the non-glue portion 206b of the adhesive tape cylinder 2b is not in contact with the separating protrusion 10. However, in some cases, it is supported by contact. The adhesive tape cylinder 2b is pulled out by pulling the handle 200 toward the opening 100 of the case 1 so that the inner surface 1c has only the separation protrusion 10 on the inner side X of the opening 100. In addition, there are advantages such as being able to be taken out reliably, and that the adhesive surface 206a is in contact with the inner surface 1c at this time, and is extremely reduced.

  Each structure described above is a description of a preferred example of the present invention. Therefore, the present invention is not limited to the above-described embodiments, and structures that change a part of the configuration within the scope of the invention, structures that can achieve the same features and effects, and the like are within the scope of the present invention. It is.
