Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a brush case that accommodates and covers the bristle portion of a brush such as a toothbrush.

[Conventional technology]

Generally, a case with a lid was used for toothbrush cases to contain the entire toothbrush for reasons of hygiene or to protect the brush, but for reasons of economy and ease of handling, cases have recently been made that only cover the bristles with flocked hair. Are known.

[Problem that the invention attempts to solve]

In order to make this conventional case easier to handle, the case was simply inserted into the brush part, but due to the friction fit with the toothbrush, the cap often fell off, and in order to prevent this, the case was either too tight or too loose. This posed a manufacturing problem as dimensional accuracy was required to ensure that no damage occurred. In addition, using a cap with a bottom that opens and closes using a hinge will ensure that it does not fall out, but on the other hand, when opening it, the user must use a small knob to open it, making it difficult for children and the elderly to open and creating handling problems. It was hot.

The present invention aims to accurately eliminate these conventional drawbacks by providing a cap-shaped brush case that is easy to open and close, is easy to handle, and does not fall easily.

[Means for solving problems]

The present invention is a device that can fit and store the head of a brush, including the brush, and has one end as an open end serving as an insertion port 1 for the brush part, and the other end as a blind end wall 6 with a hinge 2 serving as a connecting part to the wall part. In the case A, the door section 3 is provided with a door section 3 that can be freely opened and closed, and the door section 3 has a bending piece ₃₁ as a free end that covers a part of the insertion opening 1. A spring acting part 5 consisting of a bending hinge 5' having a thin folding line near the intermediate part between the bending piece 3 ₁ and the hinge 2 at the other end is formed in a chevron shape as the top. ' and the bending piece 3 ₁ , a connecting part 4 is provided as a fulcrum,
This brush case is characterized in that the spring action of the spring action part 5 of the door part 3 is changed in the opening direction and the closing direction of the door.

〔Example〕

An embodiment in which the present invention is applied to a toothbrush case will be described with reference to the drawings.

Case A is a cap that houses the head of a toothbrush, which consists of a brush part _B1 and a flocked head part _B2 ,
It consists of a blind end wall 6 which is a fixed wall, side walls 7, 7, a bottom wall 8, and a door part 3 which is a movable wall.

The door part 3 opens the insertion opening 1 facing the blind end wall 6 to a size that allows the head of the toothbrush to be inserted and removed, and the brush part B ₁ is connected to the blind end wall 6 when the toothbrush head is attached to the toothbrush head. A member that is housed in between and closes to a size that can prevent the toothbrush from separating from the case A, and is composed of an entrance wall and an upper wall component, and functionally extends into and retreats from the insertion opening ₁ area. and a spring acting part 5 for advancing and retracting the bending piece ₃₁ are integrally molded of an elastic material such as plastic, and a blind end wall is formed at the edge opposite to the side where the bending piece ₃₁ is provided. 6
It is connected to the upper edge of the frame via a hinge 2.

That is, the door part 3 includes a flat plate member having a bent piece ₃₁ at one end and a hinge 5' near the center in a direction parallel to the hinge 2, which is formed of a thin part, and is bent with the hinge 5'. It is mounted between the side walls 7, 7 via the engagement part 4 near the center of the end on the side where the piece 3 ₁ is provided, so as to be rotatable by a predetermined angle about an axis parallel to the hinge 2,
In addition, the end opposite to the side on which the bent piece 3 ₁ is provided is connected to the blind end wall 6 via the hinge 2 , but the door portion 3 is shorter than the straight line distance between the hinge 2 and the connecting portion 4 . The length from the hinge 2 to the engaging part 4 is set to be longer, and the door part 3 between the hinge 2 and the engaging part 4 is used as a spring acting part 5.

Accordingly, the spring-acting portion 5, with the hinge 5' as a bent portion, assumes either an outwardly bulging state or an inwardly recessed state depending on the direction of pressing. That is, if the equilibrium point is when the spring acting part 5 is on a plane connecting the hinge 2 and the engaging part 4, then when a force is applied outward beyond the equilibrium point, the spring acting part 5 bulges. A restoring force is generated, and when a force is applied inward, a restoring force is generated that causes a dent.

The bending piece ₃₁ is provided so as to close the insertion port 1 when the spring acting portion 5 is in the bulged state, and to open when the spring acting portion 5 is in the recessed state.

The side walls 7, 7 are formed in a shape that follows the expanded state of the spring acting portion 5.

Note that the door portion 3 is integrally molded with the fixed wall to form the blind end wall 6.
The hinge 2 may be formed by a cut or a thin part at the boundary between the door part 3 and the door part 3. Alternatively, the hinge 2 may be formed separately from the fixed wall and the door part 3
Alternatively, the connection can be made via the hinge 2 integrally formed on the blind end wall 6 or the hinge 2 formed as a separate member.
Alternatively, the entire spring acting portion 5 may be mounted in a curved state without providing the hinge 5'. Further, the case A may be provided with holes or gaps for ventilation and drying as appropriate, or a part or all of each wall portion may be openworked to serve as a vent that also serves as a decoration.

When attaching and detaching the case A from the toothbrush, if the vicinity of the hinge 5' of the spring acting part 5 is pressed inward until it exceeds the equilibrium point, even if the pressure is stopped, it will be displaced to the predetermined concave state by the restoring force. Maintain that state. At this time, the door section 3 on the bending section 3 ₁ side of the hinge 5'
rotates around the branch 4, so the branch 4
The door portion 3 on the side of the bent portion 3 ₁ rotates outward and becomes the open position, allowing insertion and removal of the toothbrush head from the insertion opening 1. When installing, after inserting the head, insert the door part 3 on the side of the folding piece 3 ₁ from the engaging part 4 that is rotating outward, that is, the folding piece 3 ₁ or the engaging part 4 and the folding piece 3 ₁ . When the door part 3 between the two parts is pressed so as to rotate inward until the spring action part 5 bulges beyond the equilibrium point, the spring action part 5 shifts to a predetermined bulge state with restoring force, Therefore, the bent piece ₃₁ also rotates to the closed position, and the case A
is securely attached to the toothbrush head.

In addition, in the examples shown in FIGS. 1 and 2, there are two hinge parts that allow the spring acting part 5 to move beyond the equilibrium point from the bulged state to the depressed state, but it cannot go beyond the equilibrium point and therefore It is possible to have a structure that does not allow it to be in a recessed state, that is, a structure that opens by pushing it, keeps the open state by continuing to push it, and closes it when you stop pushing it.

FIG. 3 shows an example of this. Since the engaging part 4 is located below the extension surface of the upper end surface of the blind end wall 6, the spring acting part 5 comes into contact with the upper end of the blind end wall 6 and exceeds the equilibrium point. It never dents and always has the ability to return to its bulging state above the equilibrium point. In addition to this example, in FIGS. 1 and 2, the upper end surface of the blind end wall 6 is formed with a slope so that the engaging part 4 is located below the extension surface, and the spring acting part in the engaging part 4 and the hinge 2 is This is possible by restricting the rotational angle range of the bending piece 3 1 , but in any case, the bending piece 3 ₁ should be set to be displaced only to open and close the insertion opening 1 .

The example shown in FIG. 4 is an example in which a spring-acting portion 5 formed into a chevron-shaped bulge is used.
In this example, the spring acting portion 5 has a restoring force to return to a predetermined bulged state no matter how it is deformed. Therefore, since the bending piece ₃₁ is always biased in the direction of closing the insertion port 1, the open state is maintained by continuing to press the spring acting part 5 downward, and when the pressing is stopped, the restoring force returns to the closed state. It is something.

Note that in order to open the insertion port 1, it is necessary to move the bent piece ₃₁ to the open position, but this may be difficult due to the strong restoring force of the spring. In that case, a structure in which the pivot point of the connecting part 4 is moved, for example, by providing a long groove 4 ₁ in the side wall that is substantially parallel to the bottom wall 8 and protruding a pin 4 ₂ that fits into the long groove 4 ₁ from the door part 3,
A smooth transition to the open state can be achieved.

FIG. 5 shows an example in which case A has protruding walls 9, 9, which are fixed walls, integrally provided at the entrance. This protruding wall 9,
9 is capable of contacting the bristle head part B ₂ of the toothbrush, and is designed so that the neck part of the toothbrush (handle part thinner than the bristle head part B ₂ ) can be inserted between the protruding walls 9 and 9, and the shoulder part 3
When the opening is open, the toothbrush head can be inserted, and when the opening is closed, together with the folding piece ₃₁ , the entrance wall is formed so as to protrude from both lower corners of the entrance.

Therefore, the case A and the toothbrush are prevented from coming off by the engagement between the protruding walls 9, 9 and the bristle head part _B2 , and the bending piece ₃₁ and the brush part _B1 come into contact with each other to prevent the toothbrush from coming off. Compared to the types shown in Figures 1 to 4, the brush part
B ₁ has the advantage of not being damaged.

Note that the protruding walls 9, 9 can also be provided at both lower ends of the bent piece ₃₁ .

Although the explanation has been given above using a toothbrush as an example, the present invention can also be applied to other brushes.

[Effect of idea]

In the present invention, the door part is provided with a free end of a folded piece that covers a part of the insertion opening, and a thin folded line is provided near the intermediate part between the folded piece and the hinge at the other end. A spring-acting part consisting of a bending hinge is formed in a chevron shape as the top, and an engaging part is provided between the bending hinge and the bending piece as a fulcrum, and the spring-acting part of the door part is used to control the opening direction of the door. By configuring the spring action to change in the closing direction, the door is opened and closed by the pushing action of the two parts, the bending piece and the spring action part, and the switching spring action allows the door to be opened and closed. In addition to ensuring that the condition is maintained, the cap has a door that can be opened and closed with a single touch, making it easy to open and close the cap, and to attach and detach the brush without requiring dimensional accuracy. The brush case is reliable and does not fall out.
