Description

The present invention relates to a compact container in which a lid body is provided on a container body so that it can be opened and closed by a rotation mechanism.

2. Description of the Related Art Compact containers are known in which a container body for storing cosmetics such as powder foundation and blush is provided with an openable and closable lid. In order to connect the lid body to the container body in an openable and closable manner, for example, a hinge piece is provided on each of the container body and the lid body, a shaft hole is formed in each hinge piece, and a hinge pin is inserted into the shaft hole. A hinge structure is known in which the lid is rotatably connected to the main body.

Conventionally, metal pins have been mainly used in such hinge structures, but resin pins have also been used as disclosed in Patent Document 1, for example. By using resin pins, it is possible to save the labor of sorting at the time of disposal, which is also excellent for promoting the recycling of resin products. Further, by employing resin pins, the compact container can be made lighter and less expensive, and is also suitable as a container for so-called low-priced cosmetics.

By the way, some compact containers have a spring pin inserted into the insertion hole and a free stop mechanism realized by the frictional force generated between the spring pin and the insertion hole. The free stop mechanism is a mechanism that allows the lid to be held at the current angle when the rotation of the lid is stopped. According to the free stop mechanism, the lid can be held in an inclined state with respect to the container body, so the user can adjust the angle to easily check the mirror.

However, generally spring pins are made of metal. Even if the spring pins are replaced with resin pins, it is difficult to obtain sufficient frictional force to hold the lid provided with the mirror in an inclined state with respect to the container body. Therefore, it has been difficult to realize a free stop mechanism using resin pins. Further, even if a free stop mechanism could be realized, it was difficult to maintain the free stop function for a long period of time.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a compact container equipped with a free stop mechanism that allows the lid to be held on the container body at an angle that is easy for the user to use without using metal parts.

The present invention includes a container body, a lid body that covers the top surface of the container body, a resin turning pin that rotatably supports the lid body on the container body, and a rotating pin provided on one side of the container body. , a compact container provided with a rotation mechanism that rotatably supports the lid with respect to the container body, the lid being rotated when the rotation angle of the lid is within a predetermined range; A free stop mechanism is provided to support at any rotation angle, and the free stop mechanism is provided with a side wall provided along the one side of the container body and protrudes outward above the side wall. a pressing frame made of an elastic material and having an upper wall portion; and a pressing frame provided on the one side side of the lid body, and when the rotation angle of the lid body is within the predetermined range, the side wall portion and a rotating wall portion having a sliding surface having a contact point with the upper wall portion, the sliding surface drawing an arcuate trajectory when the lid body is rotated by the rotating mechanism. while sliding on the side wall portion and the top wall portion at the contact point , the side wall portion includes a convex portion that contacts the sliding surface at the contact point, and the top wall portion slides on the sliding surface at the contact point. When the lid body is rotated by the rotation mechanism, the convex portion of the side wall portion comes into contact with the sliding surface, and when the lid body is further rotated, the convex portion contacts the sliding surface. Both the convex portion of the side wall portion and the convex portion of the upper wall portion contact the sliding surface, and of the two convex portions, only the convex portion of the side wall portion contacts the sliding surface. In this state, the function of the free stop that holds the lid at the angle at that time when the rotation of the lid is stopped does not work, and the convex portion of the side wall portion and the convex portion of the top wall portion do not function. When both of the two convex portions are in contact with the sliding surface, the compact container functions as the free stop due to friction between the two convex portions and the sliding surface .

In the compact container of the present invention, it is preferable that when the lid is in a closed state, the sliding surface and the pressing frame are not in contact with each other.

In the compact container of the present invention, the rotation mechanism includes the rotation pin integrally molded with the lid, and a pin receiver provided on the container body side and rotatably supporting the rotation pin. However, it is preferable that when the sliding surface of the rotating wall portion is pressed by the side wall portion and the upper wall portion, the rotating pin is pressed against the pin receiver.

In the compact container of the present invention, it is preferable that a resin mirror is provided on the surface of the lid on the container body side.

In the compact container of the present invention, the lid is rotatably supported with respect to the container body by a rotation mechanism provided on one side of the container body. Further, the compact container has a side wall portion provided along one side of the container body, and an upper wall portion provided above the side wall portion to protrude outward, and a pressing frame made of an elastic material. and a rotating wall portion provided on one side of the lid body and having a sliding surface having a contact point with the side wall portion and the top wall portion when the rotation angle of the lid body is within a predetermined range. Equipped with a free stop mechanism. According to the free stop mechanism, when the lid body is rotated by the rotation mechanism, the sliding surface of the rotation wall part is pressed by the pressing frame while drawing an arcuate trajectory, and is pressed against the side wall part and the top wall part. slide against. At this time, the rotating wall portion receives a pressing force from the side wall portion and a pressing force from the top wall portion. Since the pressing frame is made of an elastic material, it comes into close contact with the sliding surface and applies an elastic pressing force, thereby acting as a brake to restrict the rotational movement of the lid. Therefore, when the rotation operation of the lid is stopped, the lid does not rotate any more and is held on the container body at the angle at that time. For example, since the pressing frame can be constructed using the elastic force of an elastic material such as rubber or elastomer, the lid can be moved into the container at an angle that is easy for the user to use, without using metal parts such as spring pins as in the past. A free stop mechanism that can be held on the main body can be realized.

A resin mirror is a highly transparent resin substrate made of acrylic resin, carbonate resin, etc., also known as organic glass, on which metals such as aluminum or silver are deposited by vacuum evaporation, or on these resin substrates. A product with a mirror film attached. Compared to glass mirrors obtained by depositing metal on the surface of glass equipment, resin mirrors are lighter and cheaper.

The lid body 20 is provided with elements that constitute the rotation mechanism 30 and the free stop mechanism 40. As an element constituting the rotation mechanism 30, a rotation pin 31 is provided on one side 20a of the lid 20 (see FIGS. 2(a) and 2(b)). Further, as an element constituting the free stop mechanism 40, a rotating wall portion 41 is provided on one side portion 20a of the lid body 20. Note that the one side 20a side of the lid 20 refers to the side connected to the one side 10c of the container body 10 via the rotation mechanism 30.

These structures will be explained with reference to FIGS. 3 and 4. FIGS. 3(a) and 3(b) are a side view and a sectional view of the lid 20 with one side portion 20a disposed on the right side in the drawing. The sectional view shown in FIG. 3(b) is a sectional view taken along the line DD in the view of the lid body 20 shown in FIG. 3(c) from the back surface 23.

As shown in FIGS. 3(a) and 3(b), the rotating wall portion 41 is connected to the lid body 20 via the connecting portion 42 which is connected to hang down below the hanging wall portion 22 of the lid body 20. It is provided on one side portion 20a. The rotating wall surface portion 41 has an elongated semi-cylindrical shape along the longitudinal direction of the one side portion 20a of the lid body 20, and includes a sliding surface 41a having a substantially semicircular cross section. A sliding surface 41a is rotatably inserted therein about the center axis O of the rotary pin 31. Further, the length L1 of the rotating wall portion 41 in the longitudinal direction is approximately 70% of the length L2 of the one side portion 20a of the lid body 20.

Further, both ends of the rotating wall portion 41 and the connecting portion 42 are closed by a substantially circular end surface portion 43 (see FIG. 3(a)). A rotation pin 31 is provided on each end surface portion 43 . The rotation pin 31 is a short pin provided so as to protrude outward from each end surface portion 43, and its axial direction is parallel to the longitudinal direction of the one side portion 20a of the lid body 20.

The lid body 20, the rotating wall portion 41, the connecting portion 42, the end surface portion 43, and the rotating pin 31 are integrally molded from the thermoplastic resin material by injection molding or the like.

Next, the components of the rotation mechanism 30 and the free stop mechanism 40 provided on the container body side will be explained with reference to FIGS. 4 and 5. FIG. 4 is a plan view (a), a sectional view taken along the line BB (b), and a sectional view taken along the line CC (c) of the middle frame body 12. FIGS. 5(a) to 5(c) are enlarged views showing the configuration of one side 10c when the container body 10 and the lid 20 are connected via the rotation mechanism 30. FIG.

As shown in FIGS. 5(a) to 5(c), the container body 10 is provided with a pin receiver 32 as a component of the rotation mechanism 30 and a pressing frame 45 as a component of the free stop mechanism 40. The pin receiver 32 is a shaft hole that rotatably supports the pivot pin 31, and the pivot pin 31 is inserted into the pin receiver 32. In this embodiment, the pin receiver 32 includes a semi-cylindrical lower member 32a that is open at the top and a semi-cylindrical upper member 32b that is open at the bottom. The lower member 32a is provided on the bottom wall portion 11a of the outer frame 11, and the upper member 32b is provided on the middle frame 12.

As shown in FIG. 4(b), the upper member 32b is connected to the middle frame body 12. When the middle frame body 12 is fitted into the outer frame body 11, the upper member 32b and the lower member 32a are combined to form a pin receiver 32 as a shaft hole (see FIG. 5). Further, as shown in FIG. 4(a), pin receivers 32 are provided at both ends of one side 10c of the container body 10. As shown in FIGS. 5(a) to 5(c), the inner diameter of the pin receiver 32 is slightly larger than the outer diameter of the pivot pin 31, and the pivot pin 31 can be inserted into the pin receiver 32 without being press-fitted. considered to be as large as possible.

Next, the press frame 45, which is a component of the free stop mechanism 40, will be explained. As shown in FIG. 4(c) and FIGS. 5(a) to 5(c), the pressing frame 45 includes a first pressing frame 46 and a second pressing frame 47. The first pressing frame 46 includes a first side wall portion 46a made of the middle frame wall portion 12b of the middle frame body 12, and a first upper wall portion 46b provided above the first side wall portion 46a so as to protrude outward. There is. The second pressing frame 47 includes a second side wall 47a provided along the first side wall 46a, and a second side wall 47a that protrudes outward from above the second side wall 47a and is provided along the first upper wall 46b. A second upper wall portion 47b is provided. In the state shown in FIG. 4(b) and FIG. 5(a) to (c), the pressing frame 45 has a first side wall portion 46a, a second side wall portion 47a, a first upper wall portion 46b and a second upper wall portion 47b. This gives it an inverted L shape, like the letter L flipped upside down.

As shown in FIG. 4(a), the pressing frame 45 is elongated along the longitudinal direction of one side 10c of the container body 10, and its length L3 is longer than the length L1 of the rotating wall portion 41. It is configured to be short so that the end surface portion 43 of the rotating wall portion 41 does not interfere with the pressing frame 45 when the lid body 20 rotates.

Further, in the second pressing frame 47, the second side wall portion 47a and the second upper wall portion 47b are provided with convex portions 48a and 48b that protrude from each wall surface, respectively. The convex portions 48a and 48b are provided at the contact points where the sliding surface 41a of the rotating wall portion 41 comes into contact with the second pressing frame 47 when the sliding surface 41a of the rotating wall portion 41 is inserted into the pressing frame 45 (see FIG. 5(a), (b)). Note that when the lid body 20 is in the closed state, the rotating wall surface portion 41 is retracted to the outside of the pressing frame 45, and the sliding surface 41a and the pressing frame 45 are maintained in a non-contact state (see FIG. 5). a)).

In this embodiment, the first pressing frame 46 can be molded integrally with the middle frame body 12 using the same thermoplastic resin material as the middle frame body 12. On the other hand, the second pressing frame 47 is made of an elastic material. Here, examples of the elastic material constituting the second pressing frame 47 include materials that can be easily elastically deformed when force is applied, such as rubber, thermoplastic resin elastomer, and thermosetting resin elastomer.

The first pressing frame 46 and the second pressing frame 47 are formed by molding the second pressing frame 47 using the middle frame body 12 including the first pressing frame 46 as part of a mold by so-called two-color molding. It is preferable that the pressing frame 46 and the second pressing frame 47 are integrated.

Next, the opening/closing operation of the lid 20 in the compact container 100 will be described with reference to FIGS. 2 and 5. When the lid 20 is in the closed state (see FIGS. 2(a) and 5(a)), the lid-side engaging claw 23a and the container body-side engaging claw 13a are engaged, and this lock portion 13 maintains the lid body 20 in a closed state.

When the operating portion 14b is pushed from the outside of the container body 10, the lock release member 14a moves toward the one side 10c of the container body 10, and pushes the lower part of the inclined member 13b toward the one side 10c. Accordingly, the lid side engaging claw 23a is disengaged from the container body side engaging claw 13a provided on the upper part of the inclined member 13b. When the push operation of the operating portion 14b is released, the lower part of the inclined member 13b returns to its original position, and the lid side engaging claw 23a is pushed upward by the container body side engaging claw 13a. As a result, a gap is formed between the container body 10 and the lid 20 at the other side 10d, and the lid 20 is opened.

When the other side 10d of the lid body 20 is lifted, the lid body 20 is rotated by the rotation mechanism 30 around the central axis O of the rotation pin 31. With this rotation operation of the lid body 20, the rotation wall portion 41 is inserted into the inside of the press frame 45, and the sliding surface 41a also starts rotating while drawing an arcuate trajectory. When the rotation angle θ of the lid 20 reaches the first predetermined angle (θa), the sliding tip 41b of the sliding surface 41a contacts the convex portion 48a of the second side wall 47a. This state is the state shown in FIG. 5(b).

When the lid body 20 is further rotated, the sliding tip 41b of the sliding surface 41a rotates while drawing an arcuate trajectory around the central axis O of the rotating pin 31. At this time, the sliding surface 41a slides while being pressed by the convex portion 48a of the second side wall portion 47a. At this time, the rotating wall portion 41 is pressed from the second side wall portion 47a side, and an elastic pressing force is applied in the direction indicated by the arrow in FIG. 5(b).

When the rotation angle θ of the lid body 20 reaches the second predetermined angle θb, the sliding tip 41b of the sliding surface 41a contacts the convex portion 48b provided on the second upper wall portion 47b. This state is the state shown in FIG. 5(c).

When the rotation angle θ of the lid 20 becomes equal to or greater than the second predetermined angle θb, that is, when the lid 20 is further rotated from the state shown in FIG. It slides while being pressed by the convex part 48b of 47a and the convex part 48b of the second upper wall part 47b. At this time, the rotating wall surface portion 41 is pressed from the second side wall portion 47a side and the second upper wall portion 47b side. Therefore, a pressing force is applied to the rotating wall portion 41 in the diagonally downward direction indicated by the arrow in FIG. 5(c). At this time, a pressing force in a diagonally downward direction is applied to the pivot pin 31 as well, and the pivot pin 31 is pressed against the inner wall surface of the pin receiver 32. Furthermore, since the second pressing frame 47 is made of an elastic material, when the sliding surface 41a slides against the convex portions 48a and 48b, the convex portions 48a and 48b are elastically deformed and come into close contact with the sliding surface 41a. . The diagonally downward pressing force and the frictional force acting between the sliding surface 41a and the convex portions 48a and 48 act as a brake that restricts the rotational movement of the lid body 20. Therefore, when the rotation operation of the lid 20 is stopped, the lid 20 does not rotate any more and is held on the container body 10 at the angle at that time.

According to the compact container 100 of the present embodiment described above, the free stop mechanism 40 can be realized without using metal parts such as spring pins, and the free stop mechanism 40 can be realized using an arbitrary function that is easy for the user to use when opening and closing the lid body 20. The lid body 20 can be held on the container body 10 at an angle of .

Further, according to the compact container 100 of the present embodiment, the pressing frame 45 is formed into an inverted L shape and is made of an elastic material, and the sliding surface 41a has contact points with the second side wall portion 47a and the second upper wall portion 47b, respectively. By forming a curved surface having a semicircular (arc-shaped) cross section, the free stop mechanism 40 can be realized with a simple configuration in which the sliding surface 41a and the second pressing frame 47 are brought into contact with each other at a contact point.

Here, for example, as shown in FIG. 3(b), if the sliding surface 41a is brought into contact only with the second side wall portion 47a and the sliding surface 41a is pressed only from the second side wall portion 47a side, the rotation Since the pin 31 has a smaller diameter than the pin receiver 32, it is difficult for the rotation pin 31 to move upward or downward within the pin receiver 32 and to restrict the rotation of the lid body 20. On the other hand, in the compact container 100 of the present embodiment, the sliding surface 41a is pressed not only by the second side wall portion 47a but also by the two contact points at the second upper wall portion 47b as described above, so that the rotating wall surface The portion 41 can be pressed diagonally downward by the pressing frame 45. Therefore, the rotation pin 31 is prevented from moving within the pin receiver 32, and when the rotation operation is stopped, the lid body 20 can be stably held at the rotation angle θ at that time. Furthermore, in this embodiment, since the second side wall portion 47a and the second upper wall portion 47b are provided with the convex portions 48a and 48b, respectively, the elastic pressing force can be applied more efficiently to the sliding surface 41a.

Further, in the compact container 100 of the present embodiment, the lid body 20 comes into contact with the two protrusions 48a and 48b only when the rotation angle θ is within a predetermined range (θb≦θ≦θmax), and these protrusions He is trying to make it slide with respect to parts 48a and 48b. Further, when the lid body 20 is in the closed state, the sliding surface 41a and the second pressing frame 47 are maintained in a non-contact state. Therefore, by constantly pressing the sliding surface 41a against the second pressing frame 47, it is possible to suppress deterioration over time such as fatigue of the elastic material and decrease in elastic modulus. Therefore, according to the compact container 100, the function of the free stop mechanism 40 can be maintained for a long period of time.

Furthermore, according to the compact container 100, the pivot pin 31, the connecting portion 42, and the pivot wall portion 41 can be integrally molded with the lid 20. Further, the first pressing frame 46 can be integrally molded using the same material as the middle frame body 12 on the side of the container body 10, and the second pressing frame 47 made of an elastic material can also be formed by two-color molding or the like. It can be integrated with 12. Therefore, by adopting the rotation mechanism 30 and the free stop mechanism 40 of the above embodiment, the conventional steps such as press-fitting the spring pin into the shaft hole are no longer necessary, and each member can be easily assembled. , it is also possible to reduce costs.

Furthermore, in the compact container 100 of this embodiment, a resin mirror is provided on the back surface 23 of the lid body 20 instead of a glass mirror, so that the weight of the lid body 20 side can be reduced, and the load applied to the free stop mechanism 40 can be reduced. Can be made smaller. Further, the mirror M can be provided in the compact container 100 at low cost.

Although one embodiment of the compact container according to the present invention has been described above, the present invention is not limited to the compact container 100 of the above embodiment, and can be modified as appropriate without departing from the spirit of the present invention. Of course. For example, in the above embodiment, the container body 10 includes the outer frame 11 and the middle frame 12, and the middle frame 12 is fitted into the outer frame 11. The shapes and shapes are not limited to the illustrated examples. For example, in the present embodiment, the container body 10 is shown to be rectangular in plan view, but the shape of the container body 10 may be, for example, circular, oval, or the like.

Further, although the length L1 in the longitudinal direction of the rotating wall portion 41 is approximately 70% of the length L2 of the one side portion 20a of the lid body 20, the length L1 of the rotating wall portion 41 may be changed as appropriate. can. In order to sufficiently ensure the function of the free stop mechanism 40, the length may be sufficient to hold the lid 20 on the container body 10 at any rotation angle θ within the above-mentioned predetermined range. The length L1 of the rotating wall portion 41 can be adjusted as appropriate within the range of 30% or more and 90% or less of the length L2 of the one side portion 20a of the lid body 20, and may be adjusted within the range of 50% or more and 85% or less. It is more preferable to adjust it appropriately within the range. Of course, at this time, the length of the rotation pin 31 can also be adjusted as appropriate.

Furthermore, in the compact container 100, the press frame 45 has a double structure of the first press frame 46 and the second press frame 47, and the first side wall 46a of the first press frame 46 is replaced by the middle frame wall of the middle frame 12. 12b, but these specific configuration examples are not particularly limited.
In addition, in the above compact container 100, the rotating wall portion 41 has a semi-cylindrical shape, but it may have a semi-cylindrical shape, for example, or may be not limited to a semi-cylindrical shape or a semi-cylindrical shape, but may also be a columnar shape or a cylindrical shape. Alternatively, it may have a cylindrical shape or a shape in which a part of a cylindrical shape is cut out.
