Description

This invention relates to a hairdressing and hygiene tool, and to a nail clipper case for cutting fingernails and toenails, and to a nail clipper fitted with this case.

Conventional nail clippers include the lever type, and lever type clippers are generally configured so that a pair of upper and lower blades open and close when the user presses the lever. These upper and lower blades are symmetrically shaped, and the tips of the blades meet when closed.

Generally, lever-type nail clippers come with a case that houses the main body, which has upper and lower blades at the tip, and stores the cut nails when in use. This case is sheath-shaped and stores the main body of the nail clippers, and the main body is inserted into the case, covering the sides of the main body, forming a space for storing the nails. The cut nails naturally fall into the space formed between the upper and lower springs of the main body stored inside the case, preventing the nails from scattering when cut, and allowing the cut nails to be collected and easily disposed of.

However, there is a problem in that the side wall portion surrounding the nail storage space formed by the sheath-like case covers both ends of the upper and lower blades, making it difficult to position the blade against the nail and difficult to place the blade in the correct position. This makes it difficult to align the nail to be cut, reducing operability during use.

In particular, because the side walls cover both ends of the blade, visibility is poor when applying the blade to the nail, which reduces the ease of use when cutting nails, particularly for elderly people and others with poor eyesight, leading to overcutting more nails than necessary or leaving some nails uncut.

The present invention aims to solve the above problems by providing a nail clipper case and nail clippers with this case attached that are easier to use and have a structure that provides high visibility by improving the reduced operability and difficulty in visibility while maintaining the advantage of preventing cut nails from scattering when using nail clippers.

In order to solve the above problems, the present invention provides:
A base portion having a blade at a tip thereof;
a movable part having a blade at a tip and movable toward and away from the base part by elastic force;
A case for covering at least a part of the base part or the movable part of a nail clipper, the case comprising: a lever part for closing the blades of the base part and the movable part by bringing them closer together against the elastic force,
a tip side wall portion having a protrusion that matches the side shape of the blade at the tip of the base portion in a closed state;
and a tip opening portion that opens the side of the blade at the tip of the movable portion.

In the above idea,
The base portion has a lower blade,
The movable part has an upper blade on an upper side and is joined to the base part so as to be relatively close to and separated from the base part,
The protrusion of the tip side wall portion is positioned so as to match a side shape of the lower blade in a closed state,
It is preferable that the tip opening portion is positioned so as to open the side of the upper blade.
The base portion has an upper blade on an upper side,
The movable part has a lower blade and is joined to the base part so as to be relatively movable toward and away from the base part,
The protrusion of the tip side wall portion is positioned so as to match a side shape of the lower blade in a closed state,
The tip open portion is preferably positioned so as to open a side of the upper blade.

In the above device, the nail clipper case has an opening at the tip side, and the spring part formed by bonding the base part and the movable part is shaped so that it can be inserted through the opening,
It is preferable that the tip side wall portion and the tip open portion are positioned at the opening.
The tip side wall portion and the tip open portion may be disposed on either the left or right side of the opening.

As described above, this invention provides a nail clipper case that has the advantage of preventing cut nails from scattering, while improving operability and visibility, making it easier to use and with a highly visible structure.

In more detail, in this device, the tip side wall has a convex part that matches the side shape of the blade at the tip of the base part, and the tip opening part that opens the side of the blade at the tip of the movable part makes it easier to apply the blade to the nail, makes the nail alignment more accurate, and improves cutting accuracy. In other words, the convex part of the tip side wall is a protruding part that matches the sharp parts of the blade at both ends of the lower blade, and this shaped part abuts so as to match at both ends of the lower blade, so that the tip parts of both ends of the lower blade that extend left and right are extended by the tip side wall convex part. By inserting this convex part between the nail and the outer skin of the finger, the gap between the nail and the skin is expanded, and the side end part of the lower blade is guided there, and the lower blade can be safely guided by the plastic convex part.

In addition, by opening the sides of the blade, visibility is ensured when clipping the nails, making it easier to see where to cut the nail. Improved visibility prevents overcutting or leaving behind any cuts, allowing for safe use, and the tip side wall covers the blade of the nail clippers, effectively preventing the cut nails from scattering, helping to maintain a clean environment without soiling the surrounding area. Furthermore, the removable case makes it easy to collect and dispose of the cut nails, simplifies maintenance, and allows the clippers to be kept clean at all times.

Below, an embodiment of a nail clipper case and nail clippers according to the present invention will be described in detail with reference to the attached drawings. Figures 1 to 3 show a lever-type nail clipper according to this embodiment, and Figure 4 shows a lever-type nail clipper according to a modified example. Note that the embodiments shown below are merely examples of devices that embody the technical idea of this invention, and the technical idea of this invention does not specify the material, shape, structure, arrangement, etc. of each component part as described below. The technical idea of this invention may be modified in various ways within the scope of the utility model registration claims.

As shown in Figures 1 and 2, the nail clipper 1 according to this embodiment is a lever-type nail clipper with a pair of blades that open and close vertically, and has a pair of upper blades 21a and lower blades 22a that open and close vertically, and these upper and lower pairs of upper blades 21a and lower blades 22a are formed at the tip of the main body 2. The main body 2 is composed of a base part 22 having the upper blade 21a at its tip, and a movable part 21 having the lower blade 22a at its tip and moving toward and away from the base part 22 due to elastic force.

The main body 2 is formed by bonding the base part 22 and the movable part 21 together at the rear end, and a space for storing the nails is formed by covering the side of the gap between the base part 22 and the movable part 21. The cut nails fall naturally into the space formed between the upper and lower springs of the main body 2 stored inside the case 3, preventing the nails from scattering when cut, and allowing the cut nails to be collected and easily disposed of.

The nail clipper 1 also includes a lever 4 that acts as a leverage to bring the lower blade of the base part 22 and the upper blade 21a of the movable part 21 closer together against the elastic force to close them. At least a portion of the main body part 2 is covered by the case 3.

The lever 4 is connected to the pivot 41 via the pin member 41a, and the lever 4 is rotated around this pin member 41a as an axis point, opening and closing the upper blade 21a and the lower blade 22a at the tip up and down by the principle of leverage. The base part 22 and the movable part 21 are configured to generate elasticity when the upper blade 21a and the lower blade 22a open and close by joining the rear ends of the curved plate-like members, and to bias the upper blade 21a and the lower blade 22a to the open state.

The case 3 is a sheath-shaped cover into which the main body 2, which has upper and lower blades at the tip, is inserted from the rear end to store it, and a space is formed inside the main body 2 to store cut nails when in use. The case 3 is hollow and shaped like a sheath with an opening 32 into which the main body 2 of the nail clipper is inserted, and this hollow interior has a size and shape that allows the main body 2 to be stored. When the main body 2 is inserted into this space, the side of the main body 2 is covered by the case, forming a space to store the nails. The cut nails naturally fall into the space formed between the upper and lower springs of the main body 2 stored inside the case 3, preventing the nails from scattering when cut, and allowing the cut nails to be collected and easily disposed of.

The case 3 has an opening 32 on the tip side, and the opening 32 is provided with a tip side wall 31b having a convex portion 31c that matches the side shape of the lower blade 22a at the tip of the base portion 22, and a tip opening portion 31a that opens the side of the upper blade 21a at the tip of the movable portion 21. The case 3 can be made of various materials such as plastic, wood, and metal. In particular, in this embodiment, the base portion 22 has a lower lower blade 22a, the movable portion 21 has an upper upper blade, and they are joined so as to move relatively close to and away from the base portion 22, the tip side wall 31b is positioned so as to match the side shape of the lower blade 22a, and the tip opening portion 31a is positioned so as to open the side of the upper blade 21a.

Here, the convex portion 31c is a protruding portion that matches the sharp portions of the blade at both ends of the lower blade 22a in the closed state, and this shaped portion abuts so as to match at both ends of the lower blade 22a in the closed state, and in a top cross section, the tip portions of both ends of the lower blade extending to the left and right are extended by the convex portion 31c of the tip side wall portion 31b of the case 3. By inserting this convex portion 31c between the nail and the outer skin of the finger, the gap between the nail and the skin is expanded, and the side end portion of the lower blade 22a is guided there, and the lower blade 22a can be safely guided by the plastic convex portion 31c.

(How to use)
The nail clipper 1 according to the present embodiment, which has the above-described configuration, is designed to improve the ease of use of conventional lever-type nail clippers, and is excellent in operability and visibility. First, when using the nail clipper 1, the main body 2 is held by hand, and the main body 2 is provided with a pair of upper blades 21a and lower blades 22a that open and close vertically, and the nail is cut by this pair of upper and lower blades. The tip of the nail clipper is placed on the nail, and the upper blade 21a and the lower blade 22a are accurately aligned with the position of the nail, and at this time, the tip side wall portion 31b and the tip open portion 31a improve visibility and facilitate accurate alignment.

Next, the nail is cut by operating the lever 4. The lever 4 is connected to the pivot 41 of the main body 2 via the pin member 41a, and by rotating the lever 4 around this pin member 41a as an axis point, the lever 4 pushes down and closes the upper blade 21a using the principle of leverage. When the lever 4 is pushed down, the upper blade 21a and the lower blade 22a approach each other, clamping and cutting the nail. After cutting, the lever 4 is returned, and the upper blade 21a and lower blade 22a return to their original positions, ready for cutting the next nail.

In addition, when cutting nails, the case 3 prevents clippings from scattering. The sheath-shaped case 3 that covers the main body 2 serves as a space to store cut nails during use, and the cut nails naturally fall into the space formed between the upper and lower springs inside the case 3, so they are efficiently collected without scattering.

(Example of change)
The above-described embodiments are merely examples of the present invention, and therefore the present invention is not limited to the above-described embodiments, and various modifications may be made according to the design, etc., without departing from the technical concept of the present invention.

In the above embodiment, the base part 22 having the lower blade 22a is fixed, and the movable part 21 having the upper blade 21a moves relative to it, with the tip side wall part 31b positioned below the opening 32 and the tip open part 31a positioned above the opening 32, but the present invention is not limited to this.

For example, if the nail clippers are structurally such that the movable part is located on the lower side, the shape of the opening 32 may be designed so that the tip side wall 31b is located on the lower side of the opening 32 and the tip open part 31a is located on the upper side of the opening 32. In this case, the tip side wall 31b is positioned to match the side shape of the lower blade 22a, and the tip open part 31a is positioned to open the side of the upper blade 21a. This configuration further improves operability and visibility during use, making the design easy to use, especially for delicate work and for elderly people who are concerned about declining eyesight.

Also, as shown in FIG. 4, the tip side wall portion 31b and the tip open portion 31a may be arranged on either the left or right side of the opening 32. This change in arrangement allows customization according to the user's dominant hand and ease of operation, realizing a flexible design that can also accommodate left-handed users. Furthermore, by changing the position and shape of the opening 31, it is possible to provide nail clippers specialized for specific purposes, and to respond to situations where specialized care is required.

In this way, this invention can be flexibly modified to meet diverse needs, enhancing the convenience and satisfaction of users. By appropriately combining each component, it is possible to provide a more user-friendly and functional product, thereby creating new value.
