Description

  The present invention relates to a cat nail sharpener used when a cat sharpens its claws.

  In general, cats have an instinct to sharpen their nails, and especially cats kept as pets in the home use home pillars, walls, floors, furniture, curtains, carpets, etc. to relieve stress. May be damaged by scratching with nails.

  Therefore, conventionally, in order to prevent furniture and indoor damage caused by cat nails, a plurality of corrugated cardboard pieces are bonded with an adhesive, and the flute end surfaces of each corrugated paper are continuously formed to form a nail sharpening part. A vessel is used.

  For example, Patent Document 1 discloses a cat nail sharpener in which a laminated cross section is impregnated with a synthetic resin in a cat nail sharpener in which corrugated cardboard is laminated and bonded with an adhesive or the like.

  In addition, a nail sharpener made of a large number of corrugated cardboard bonded with an adhesive is made into a gentle M-shape, for example, so that a cat can easily relax on it (Non-patent Document 1). A crocodile shape is sold on the Internet (Non-patent Document 2).

  However, conventional cat nail sharpeners use a process in which adhesive is applied to the liner surfaces of a plurality of cardboard pieces that have been die-cut into a desired shape, or the cardboard pieces are joined together. A process of cutting the required shape into a required shape is indispensable, and in these respects, there is a problem of increasing the cost at the time of production.

  In addition, since the conventional cat nail sharpener is integrated with an adhesive at the time of completion, even if only a part of the nail sharpening part with the continuous flute end face is damaged by continuous use, it is integrated. There is also a problem that it is not economical because it is necessary to replace all the corrugated cardboard pieces.

  Furthermore, in the conventional cat nail sharpener, the adhesive used in the gluing process to join the corrugated cardboard pieces leaks to the nail sharpening surface, so when the cat sharpens the nail, it is exposed to the nail sharpening surface. There is a risk that the adhesive that is being used will be licked, so that the owner is worried about use.

  The present invention achieves the object of eliminating the step of applying an adhesive and joining the cardboard pieces together in a cat's nail sharpening device that forms a nail sharpening portion by continuing the flute end surfaces of a plurality of cardboard pieces. In addition, a configuration in which a plurality of corrugated cardboard pieces are detachably overlapped with each other and a plurality of corrugated cardboard pieces are separately bound in an overlapping direction using a binding means is employed.

  Hereinafter, the best mode for carrying out the present invention will be described with reference to FIGS.

  The cat's nail sharpener T1 of the first embodiment shown in FIG. 1 does not join and integrate, for example, 40 cardboard pieces 11, but stacks them in the width direction in a separable state. The nail sharpening portion 2 is constructed by arranging the flute end face composed of the liner of the piece 1 and the corrugated core to be continuous. The nail sharpening part 2 has a sufficient area even when a grown adult cat uses it.

  Reference numeral 3a denotes a cap which is one of members constituting a binding means for binding a plurality of cardboard pieces 1 in the overlapping direction. The cap 3a is also present on the opposite surface that is not visible in FIG. Reference numeral 4 denotes decorative paper affixed to the liner surface of the outermost corrugated cardboard piece 1. The “overlapping direction” of the cardboard pieces 1 is synonymous with the width direction of the cat's claw sharpener T1 (in the example of FIG. 1, the thickness direction is equivalent to 40 cardboard pieces).

  FIG. 2 is a view showing a state in which one of the caps 3a is removed and a plurality of corrugated cardboard pieces 1 that have been bound are separated. As shown in FIG. 2, the cat's nail sharpener T1 of this embodiment has a cap 3a that is detachably attached to a paper tube 3b that passes through an opening 1a provided in each cardboard piece 1. For example, it is possible to replace only the portion of the center nail sharpening portion 21 that is severely damaged by nail sharpening with a new one, and continue to use the portions of the nail sharpening portions 22 and 23 at both ends where the damage has not progressed to the left. Yes, paper resources can be valued.

  Also, the conventional nail sharpener has an adhesive that is exposed on the nail sharpening surface when the cat sharpens the nail because the adhesive used in the gluing process for joining the cardboard pieces leaks to the nail sharpening surface. However, the nail sharpening device T1 of the present invention does not perform the gluing step, so that there is less risk of harming the cat. Users can use it with peace of mind.

  FIG. 3 is a diagram showing one of the two cardboard pieces located at both ends in the overlapping direction among the plurality of cardboard pieces 1. The present invention is characterized in that no adhesive is used between the corrugated cardboard pieces, but in the first embodiment, only two corrugated cardboard pieces positioned at both ends in the overlapping direction are provided on the outer liner. The decorative paper 4 is pasted on. The corrugated cardboard piece 1 used in the present embodiment has a motif of the shape of Son Goku's muscle cloud as shown in FIGS. 3 (a) and 3 (b). Is used to produce an image of a muscular cloud.

  FIG. 3C is a view of the corrugated cardboard piece 1 seen from the lateral direction, and shows a flute end face 1d composed of two upper and lower liners 1b and a corrugated core 1c. The above-described nail sharpening portion 2 is configured such that such a flute end face 1d is continuously formed in the width direction.

  FIG. 4A shows the entire paper tube 3b of FIG. The paper tube 3b is a cylindrical member, and both ends are openings 3b1. FIG. 4 (b) shows the bundling means 3 of this embodiment comprising a cap 3a and a paper tube 3b. That is, the bundling means 3 is composed of a paper tube 3b penetrating through an opening 1a provided in each of a plurality of cardboard pieces 1, and caps 3a attached to the openings 3b1 at both ends of the paper tube 3b.

  FIG. 5 is a diagram showing the structure of the resin cap 3a. The cap 3a has a disc-shaped flange portion 3a1 having a larger size than the diameter of the opening 1a of the corrugated cardboard piece 1, and a fitting portion 3a2 having an outer diameter size that fits just inside the opening 3b1 of the paper tube 3b. Have. Therefore, when the fitting portions 3a2 of the cap 3a are pushed into the openings 3b1 at both ends of the paper tube 3b in a state where the paper tubes 3b are passed through the openings 1a of the plurality of cardboard pieces 1, the plurality of cardboard pieces 1 become flanges. The state pressed toward the center by the protrusion of the portion 3a1 is maintained.

  3a3 shows four convex portions (ribs) provided on the outer surface of the fitting portion 3a2 so that the cap 3a is not easily detached by applying an appropriate load when fitted into the paper tube 3b. Yes. Reference numeral 3a4 denotes a hole provided in the center of the flange portion 3a1 so that air inside the paper tube 3b can easily escape when the cap 3a is pushed in from both ends of the paper tube 3b. When such a hole 3a4 is provided, the cap can be easily attached and detached.

  Next, the configuration of the cat's claw sharpener T2 of the second embodiment will be described with reference to FIG. In the second embodiment, for example, 40 cardboard pieces 11 are used, and the cardboard pieces 1 are not bonded to each other but are arranged in the width direction so as to be separated so that the flute end faces of the cardboard pieces 1 are continuous. The nail sharpening portion 2 is configured in the same manner as in the first embodiment, and there is no change in these points.

  The second embodiment is different from the first embodiment in that a desired design (for example, arabesque pattern) is applied to the outer liner surface of the cardboard pieces 1 located at both ends in the overlapping direction among the plurality of cardboard pieces 1. This is the point where the first fabric 5 is sewn.

  That is, in the second embodiment, since the first fabric 5 is attached to the outer liner surfaces of the two corrugated cardboard pieces 1 located at both ends in the overlapping direction by sewing, the policy of the present invention is not used. it can.

  As shown by the suture line 5a in FIGS. 7 (a) and 7 (b), the first fabric 5 is sewn using a sewing machine at a position slightly inward from the peripheral edge of the corrugated cardboard piece 1 having the shape of a myocardium. Thus, it can be firmly sewn to the liner surface of the cardboard piece 1.

  FIG. 8 is a diagram showing the structure of the cap 3a in the second embodiment. In the second embodiment, the cap 3a includes a flange portion 3a1 having a size larger than the diameter of the opening 1a of the corrugated cardboard piece 1. Out of the corrugated cardboard pieces 1, the outer side of the corrugated cardboard piece 1 located at both ends in the overlapping direction is provided. The first fabric 5 is sewn to the liner surface, and the second fabric 6 is attached to the cap 3a so as to cover the outer surface of the flange portion 3a1 as shown in FIG.

  That is, since the second fabric 6 can be given an arbitrary design that suits the user's preference, as with the first fabric 5, as shown in FIG. Of course, if a plurality of caps 3a in which the design of the second fabric 6 is changed is prepared, the user can enjoy variations of the design.

  Further, as shown in FIG. 9, an overlap margin 5 b is provided on the first fabric 5 so as to overlap the opening range of the opening 1 a provided on the cardboard piece 1.

  Accordingly, when the fitting portions 3a2 of the cap 3a are pushed into the openings 3b1 at both ends of the paper tube 3b in a state where the paper tubes 3b are passed through the openings 1a of the plurality of cardboard pieces 1, the fitting portions 3a2 are overlapped. It is fitted with the opening 3b1 of the paper tube 3b so as to retract the portion 5b.

  In other words, the presence of the overlap allowance 5b enables the cap 3a to be securely attached to the paper tube 3b more firmly than the first embodiment in the second embodiment, and the first fabric 5 is wrinkled. It can be attached to the liner surface in a beautiful state that is tensioned.

  FIG. 10 shows an example of the layout when the cardboard piece 1 is die-cut. The design based on the myo-clouds used in the above embodiment can be used efficiently by corrugated cardboard with less waste of paper resources, as shown in FIG. it can.

  The present invention is not limited to the above example, and it goes without saying that the embodiments may be changed as appropriate within the scope of the technical idea described in each claim.

  For example, to prevent paper dust generated when a cat sharpens nails from reaching the lower surface of the nail sharpener through a small hole in the flute end face of each corrugated cardboard piece and soiling the floor, A tray for receiving paper dust may be provided.

  Moreover, in the said Example, although the example which pushes a resin cap into a paper tube was shown as a binding means, you may bind using another means. For example, a resin tube having a threaded end may be used and a screw cap may be attached.

  In the above embodiment, an example in which two cylindrical paper tubes are passed through a plurality of cardboard pieces and bound with a cap has been shown. However, the shape and number of members constituting the binding means are described in the embodiment. Not limited to those shown.
