Abstract
Description
Technical Field
[0001] The present invention relates to a container for feeding out a rod-shaped material.
Background Art
[0002] As a feeding-out structure of a container for feeding out a rod-shaped material, a so-called double spiral structure is known (for example, Patent Documents 1 and 2). In the double spiral structure, two spiral members having spiral grooves on the peripheral surface are provided inside and outside in the radial direction. The spiral grooves of the spiral members are engaged with adjacent members, and by this engagement, the rotational motion can be converted into a vertical motion. Therefore, the spiral members can be easily raised and fed out by the rotational operation of the user. In a feeding-out container having a double spiral structure, the lengths fed out by each of the two spiral members are added as the feeding-out length of the rod-shaped material (the stroke in which the rod-shaped material rises by the operation). Therefore, the feeding-out length can be increased while the feeding-out mechanism is compactly configured in the vertical direction.

Summary of the Invention
Problems to be Solved by the Invention
[0004] As a feeding-out container, one in which a rod-shaped material is configured to be replaceable is also known. In such a feeding-out container, it is preferable to be configured such that when the rod-shaped material is fed out, the lower end of the rod-shaped material is exposed so that the rod-shaped material can be easily replaced. Thus, there may be a case where it is desired to further increase the feeding-out length of the rod-shaped material.
[0005] In a rod-shaped material feeding container having a conventional double-helix structure, the feeding mechanism including the helical member is housed below the lower end of the rod-shaped material. Therefore, in order to further increase the feeding length, it is necessary to lengthen the feeding mechanism, which in turn requires lengthening the entire rod-shaped material feeding container. When the overall length of the rod-shaped material feeding container increases, it may become inconvenient for carrying or handling, which may not be preferable. On the other hand, if the feeding mechanism below the rod-shaped material is lengthened without changing the overall length of the feeding container, the length of the rod-shaped material has to be shortened, resulting in a reduced amount of rod-shaped material that can be used, and the rod-shaped material can only be used for a short period of time.
[0006] Therefore, an aspect of the present invention aims to provide a rod-shaped material feeding container that maintains a short overall length while further increasing the feeding length of the rod-shaped material.
Means for Solving the Problems
[0007] To solve the above problems, in one aspect of the present invention, there is provided a rod-shaped material feeding container including a receiving portion for receiving a rod-shaped material, a rod-shaped material holding portion (3) having a screw shaft extending downward from the bottom surface of the receiving portion, an outer cylinder (8), and an intermediate mechanism (5, 6, 7) that enables vertical movement of the screw shaft by rotation of the outer cylinder (8). The outer cylinder (8) is provided with an inner screw in the outer cylinder, and the intermediate mechanism (5, 6, 7) includes an inner engaging portion that engages with the screw shaft and an outer engaging portion that engages with the inner screw in the outer cylinder. The outer cylinder (8) is disposed radially outside the receiving portion, and in the bottom dead center state, the upper end of the inner screw in the outer cylinder is located above the lower end of the bottom surface of the receiving portion.
Effects of the Invention
[0008] According to one aspect, it is possible to provide a rod-shaped material feeding container that increases the feeding length of the rod-shaped material while maintaining a short overall length in the rod-shaped material feeding container.

Embodiments for Carrying Out the Invention
[0010] Hereinafter, embodiments of the present invention will be described with reference to the drawings. One embodiment of the present invention is a feeding container for a rod-shaped material (stick-shaped material). The rod-shaped material may be a solid formed in a predetermined shape or a form that can maintain a predetermined shape in a stationary state.
[0011] The feeding container according to this embodiment can be suitably used as a feeding container for rod-shaped cosmetics. Specific examples of rod-shaped cosmetics include lipsticks, lip creams, concealers, stick eyeshadows, stick blushes, stick foundations, etc. Also, cosmetics having a predetermined function such as skin care liquids (cosmetics), moisturizers, and whitening agents may be formed into a rod shape. Further, the rod-shaped material may be something other than cosmetic materials, for example, personal care products (hygiene products) such as antiperspirants, sunscreens, hair dyes, solid perfumes, and insect repellents. Furthermore, the rod-shaped material may be a solid detergent, paste, adhesive, eraser, or a toy imitating cosmetics.
[0012] FIG. 1 shows a perspective view of the rod-like material feeding container 100 according to this embodiment. FIG. 2 shows an exploded view of the rod-like material feeding container 100. Further, FIG. 3 shows a cross-sectional view taken along line I-I of FIG. 1, that is, a cross-sectional view cut along the vertical direction (axial direction), and FIG. 4 shows a cross-sectional view taken along line II-II of FIG. 1, that is, a view cut in a cross-section that is in the vertical direction but orthogonal to the cross-section of line I-I. FIGS. 1, 3, and 4 show the rod-like material feeding container 100 in a state before the rod-like material is fed out or in a state where the rod-like material is completely accommodated, that is, in the bottom dead center state.
[0013] As shown in FIG. 1, the rod-like material feeding container 100 generally has an elongated substantially cylindrical shape. The rod-like material feeding container 100 may include a cap 10 for covering from above, as shown by a dashed-dotted line in FIG. 4. The cap 10 may have a shape and size such that the outer peripheries of the cap 10 and the outer cylinder 8 are flush with each other when the cap 10 is put on.
[0014] The rod-like material feeding container 100 basically includes a rod-like material holding portion 3 for holding the rod-like material, an outer cylinder 8 that can be operated by the user, and an intermediate mechanism that enables the vertical movement of the rod-like material by the rotation of the outer cylinder 8.
[0015] The rod holding portion 3 may have a bottomed cylindrical receiving portion 3a that receives and holds the lower side of the rod, and a screw shaft 3b that extends downward from the bottom surface of the receiving portion 3a. The screw shaft 3b may be solid, or may be hollow, for example, cylindrical. The rod may be directly accommodated in the receiving portion 3a of the rod holding portion 3, or as shown in FIGS. 1 to 4, the rod 1 may be accommodated in the middle plate 2, and the middle plate 2 may be received by the receiving portion 3a. When the middle plate 2 is provided, by configuring the middle plate 2 to be detachable from the receiving portion 3a of the rod holding portion 3, the rod 1 can be easily replaced. At the time of replacement, the user can, for example, hold the side peripheral surface of the middle plate 2 and remove or attach the rod 1 together with the middle plate 2. That is, the feeding container 100 according to this embodiment can be suitably used as a feeding container in which the rod can be replaced. One or more locking protrusions 21 are provided on the side surface of the middle plate 2, and the locking protrusion 21 can engage with a notch 31 formed at the upper end of the side portion of the receiving portion 3a of the rod holding portion 3 (FIG. 2). The notch 31 is preferably formed in a substantially L shape. In that case, after the locking protrusion 21 of the middle plate 2 is inserted into the substantially L-shaped notch 31 of the receiving portion 3a from top to bottom and the middle plate 2 is received by the receiving portion 3a, the middle plate 2 can be rotated in the circumferential direction to lock the locking protrusion 21.
[0016] An external thread (external spiral groove or male thread) 32 may be provided on the outer peripheral surface of the screw shaft 3b of the rod holding portion 3. The external thread 32 may be formed on the entire outer peripheral surface of the screw shaft 3b, for example, on the entire surface of a columnar shaft. Further, as long as the function as an external thread can be maintained, it may be formed only on a part of the outer peripheral surface of the screw shaft 3b, or the external thread 32 may be discontinuous. For example, as shown in FIG. 2, the external thread 32 may be formed on two side surfaces that are diametrically opposed to each other on the outer peripheral surface of the screw shaft 3b. This shape can be said to be a shape obtained by cutting along two parallel surfaces along the vertical direction separated from the axis from a state where an external thread is formed on the entire circumferential surface of a columnar shaft. Alternatively, it can also be said that the screw shaft 3b has a shape in which an external thread is partially formed on the side surface of a rod having a substantially elliptical or substantially rectangular cross section.
[0017] The outer cylinder 8 is a cylindrical member disposed on the outermost side of the rod-shaped material feeding container 100, excluding the cap 10. The rod-shaped material feeding container 100 is provided with a basket cylinder 4 that extends substantially throughout the vertical direction of the rod-shaped material feeding container 100 (Figs. 1 to 4), but the outer cylinder 8 is disposed radially outside of this basket cylinder 4. The basket cylinder 4 is a member that houses and protects the main part of the feeding mechanism and the rod-shaped material 1, and surrounds the rod-shaped material 1 throughout the entire vertical direction in the bottom dead center state.
[0018] When the user feeds out the rod-shaped material, for example, the user can operate the feeding container 100 by pressing the basket cylinder 4 with one hand, holding the outer cylinder 8 with the other hand, and relatively rotating the outer cylinder 8 with respect to the basket cylinder 4.
[0019] An outer cylinder internal thread (inner spiral groove or female thread) 82 is formed on the inner peripheral surface of the outer cylinder 8. The outer cylinder internal thread 82 is preferably formed up to the upper end of the outer cylinder 8, but it does not have to reach the upper end of the outer cylinder 8.
[0020] The outer cylinder 8 and the rod-shaped material holding portion 3 are connected via an intermediate mechanism. More specifically, the intermediate mechanism has an outer engaging portion formed on the radially outer side of the intermediate mechanism and an inner engaging portion formed on the radially inner side. Then, on the radially outer side, the outer cylinder internal thread 82 of the outer cylinder 8 engages with the outer engaging portion of the intermediate mechanism, and on the radially inner side, the inner engaging portion of the intermediate mechanism engages with the screw shaft 3b of the rod-shaped material holding portion 3. When the user rotates the outer cylinder 8 when feeding out the rod-shaped material, the screw shaft 3b can be moved up and down through the above two engagements formed in the radial direction inside and outside (the engagement on the radially outer side between the outer cylinder internal thread 82 of the outer cylinder 8 and the outer engaging portion of the intermediate mechanism, and the engagement on the radially inner side between the inner engaging portion of the intermediate mechanism and the screw shaft 3b).
[0021] The intermediate mechanism may have a structure including one or more cylindrical members. The intermediate mechanism is formed in the radial direction between the outer cylinder 8 and the screw shaft 3b of the rod holding portion 3, and below the receiving portion 3a of the rod holding portion 3. By configuring the intermediate mechanism to be as short and compact as possible, the upper end position of the intermediate mechanism can be brought closer to the lower side, so that the receiving portion 3a of the rod holding portion 3 can be arranged lower. As a result, a larger proportion of the space for accommodating the rod 1 can be ensured in the vertical direction. If the proportion of the space for accommodating the rod 1 increases, the amount of the rod 1 can be increased, so that the rod can be used for a long period, which is preferable. However, the shorter the vertical length of the intermediate mechanism, the shorter the length of the structure (including the screw shaft 3b) for feeding out the rod, and as a result, the feeding length may become shorter.
[0022] In contrast, in this embodiment, since the outer cylinder 8 is provided on the outermost side in the radial direction, the vertical length of the outer cylinder 8 can be designed without depending on the length of the intermediate mechanism and the length of the screw shaft 3b of the rod holding portion 3. Therefore, by increasing the vertical length of the outer cylinder 8 and, accordingly, forming the inner screw 82 of the outer cylinder provided on the inner peripheral surface of the outer cylinder 8 over a wide range in the vertical direction, the movable range in the vertical direction of the intermediate mechanism engaged with the inner screw 82 of the outer cylinder 8 can be increased. If the movable range in the vertical direction of the intermediate mechanism with respect to the outer cylinder 8 can be increased, the feeding length of the rod 1 can be increased.
[0023] In this way, since the outer cylinder 8 is provided on the outermost side, it is not necessary to accommodate the outer cylinder 8 in the range below the rod holding portion 3. Therefore, for example, as shown in FIG. 3, in the bottom dead center state, the position H2 of the upper end of the inner screw 82 of the outer cylinder 8 can be made higher than the position H1 of the lower end of the bottom surface of the receiving portion 3a of the rod holding portion 3 (the position H2 can be brought closer to the tip of the rod 1 than the position H1). As a result, the movable range in the vertical direction of the outer engagement portion of the intermediate mechanism engaged with the inner screw 82 of the outer cylinder (in this embodiment, the protrusion formed on the outer periphery of the first intermediate cylinder 5, which will be described in detail later) is widened, and the rod 1 can be fed out longer.
[0024] Next, a more specific configuration of the feeding container 100 will be described. As described above, the feeding container 100 according to this embodiment includes a rod-shaped member holding portion 3 that holds a rod-shaped member, an outer cylinder 8 that can be operated by a user, and an intermediate mechanism that enables the vertical movement of the rod-shaped member by the rotation of the outer cylinder 8. Here, the intermediate mechanism may include an inner cylinder 6, a first intermediate cylinder 5, and a second intermediate cylinder 7 arranged in order from the radially inner side (Figs. 2 to 4).
[0025] An internal thread (internal spiral groove) 64 is formed on the inner peripheral surface of the inner cylinder 6. The inner cylinder internal thread 64 is the inner engagement portion of the above-described intermediate mechanism and engages with the external thread 32 of the screw shaft 3b of the rod-shaped member holding portion 3. By rotating the inner cylinder internal thread 64, the screw shaft 3b moves up and down, and thus the rod-shaped member holding portion 3, and hence the rod-shaped member 1, can move up and down.
[0026] The inner cylinder 6 is accommodated in the first intermediate cylinder 5. And the inner cylinder 6 is held by the first intermediate cylinder 5 so as to be rotatable relative to the first intermediate cylinder 5 but non-axially movable. More specifically, the first intermediate cylinder 5 is provided with continuous or discontinuous circumferential protrusions 56 formed along the circumferential direction on the upper end side of its inner peripheral surface (Fig. 3). On the other hand, a circumferential rib 62 extending along the circumferential direction is provided at the upper end of the inner cylinder 6. The circumferential rib 62 may be formed continuously in the circumferential direction or may be discontinuous in the circumferential direction (Fig. 2). In the assembled feeding container 100, the circumferential rib 62 formed at the upper end of the inner cylinder 6 is placed on the circumferential protrusion 56 of the first intermediate cylinder 5. Thereby, the inner cylinder 6 and the first intermediate cylinder 5 are relatively rotatable but can move up and down integrally. Note that the configuration for the inner cylinder 6 and the first intermediate cylinder 5 to be relatively rotatable and non-axially movable is not limited to the illustrated one. For example, a groove may be provided on the outer peripheral surface of the inner cylinder 6, and a circumferential rib may be provided on the inner peripheral surface of the first intermediate cylinder 5 at a position facing this groove, and the two may be rotatably engaged.
[0027] The first intermediate cylinder 5 has an upper surface, and an opening 55 is formed in this upper surface (Fig. 2). In the assembled state, the screw shaft 3b of the rod-shaped member holding portion 3 is disposed to penetrate the opening 55 of the first intermediate cylinder 5 (Figs. 3 and 4). The screw shaft 3b is movable up and down with respect to the opening 55 but is non-rotatable. The shape of the opening 55 may be formed to conform to the shape of the screw shaft 3b of the rod-shaped member holding portion 3 so that the screw shaft 3b is non-rotatable with respect to the opening 55. That is, the opening 55 can function as a rotation stopper for the rod-shaped member holding portion 3.
[0028] Bulging portions 53, 53 may be formed at the edge of the opening 55 of the first intermediate cylinder 5. On the other hand, a rib portion 33 extending in the vertical direction is formed on the screw shaft 3b of the rod-shaped member holding portion 3. Since this rib portion 33 can be engaged with the bulging portions 53, 53 formed in the opening 55 of the first intermediate cylinder 5 so as to be movable up and down, the screw shaft 3b can move up and down stably.
[0029] The first intermediate cylinder 5 is provided with protrusions 52 on its outer peripheral surface, and these protrusions 52 can be engaged with the internal external thread 82 of the outer cylinder 8 (Fig. 4). Further, the protrusions 52 of the first intermediate cylinder 5 are formed so as to be movable up and down within a slit 41 (Fig. 2) formed along the vertical direction in a housing cylinder 4 disposed outside the first intermediate cylinder 5. Therefore, when the user rotates the outer cylinder 8 with respect to the housing cylinder 4, the first intermediate cylinder 5 can move up and down along the slit 41 of the housing cylinder 4.
[0030] In the illustrated form, the protrusions 52 of the first intermediate cylinder 5 are formed at two diametrically opposed locations on the lower end side of the first intermediate cylinder 5, but three or more protrusions 52 may be provided on the outer peripheral surface. Further, the slit 41 of the housing cylinder 4 is formed for each protrusion 52.
[0031] A second intermediate cylinder 7 is disposed between the inner cylinder 6 and the first intermediate cylinder 5. A plurality of vertical ribs 61r, 61r,... extending along the vertical direction and a plurality of vertical grooves 61g, 61g,... between the vertical ribs 61r, 61r,... may be formed on the outer peripheral surface of the inner cylinder 6 (FIG. 2). On the other hand, a plurality of vertical grooves 71g, 71g,... extending along the vertical direction and a plurality of vertical ribs 71r, 71r,... between the vertical grooves 71g, 71g,... may be formed on the inner peripheral surface of the second intermediate cylinder 7 (FIG. 2). In the assembled state, the vertical ribs 61r of the inner cylinder 6 engage with the vertical grooves 71g of the second intermediate cylinder 7, and the vertical grooves 61g of the inner cylinder 6 engage with the vertical ribs 71r of the second intermediate cylinder 7. Therefore, the inner cylinder 6 and the second intermediate cylinder 7 can move relative to each other in the vertical direction (slidably), but are non-rotatable relative to each other. Therefore, when the second intermediate cylinder 7 is rotated, the inner cylinder 6 can rotate integrally with the second intermediate cylinder 7.
[0032] The second intermediate cylinder 7 is provided with a flange 72 protruding in the radial direction at the lower end. The second intermediate cylinder 7 can be inserted into the outer cylinder 8 from below the outer cylinder 8 and mounted during assembly. At this time, the flange 72 of the second intermediate cylinder 7 can contact the lower end surface of the outer cylinder 8 (FIGS. 3 and 4). Further, the flange 72 is not continuously formed in the circumferential direction, and one or more notches 72c may be provided. A lower end surface protrusion 85 (FIGS. 5 and 6) that can be fitted into the notch 72c may be formed on the lower end surface of the outer cylinder 8. By this fitting, the outer cylinder 8 and the second intermediate cylinder 7 are fitted and fixed. By fixing the outer cylinder 8 and the second intermediate cylinder 7, the outer cylinder 8 and the second intermediate cylinder 7 move integrally. That is, when the outer cylinder 8 is rotated, the second intermediate cylinder 7 can also rotate integrally with the outer cylinder 8. Further, the second intermediate cylinder 7 does not move up and down relative to the outer cylinder 8. The configuration in which the second intermediate cylinder 7 is fixed to the outer cylinder 8 is not limited to the above-described configuration. For example, the flange 72 of the second intermediate cylinder 7 may be adhered to the lower end surface of the outer cylinder 8.
[0033] In this way, the first intermediate cylinder 5 can move up and down with respect to the outer cylinder 8 by rotating the outer cylinder 8. Further, the second intermediate cylinder 7 is fixed to the outer cylinder 8, is incapable of moving up and down and rotating relative to the outer cylinder 8, and can rotate together with the outer cylinder 8. Furthermore, the inner cylinder 6 is accommodated in the feeding container 100 so as to be movable up and down by the first intermediate cylinder 5 and rotatable by the second intermediate cylinder 7.
[0034] Next, the movement of each member when feeding out the rod-shaped material from the feeding container 100 will be described. First, the user rotates the outer cylinder 8 with respect to the housing cylinder 4 about the axis (center line along the vertical direction) in the feeding container 100 in the bottom dead center state as shown in FIG. 3. When the outer cylinder 8 rotates, the outer cylinder internal thread (female thread) 82 of the outer cylinder 8 rotates, whereby the protrusion 52 of the first intermediate cylinder 5 engaged with the outer cylinder internal thread 82 rises, and the entire first intermediate cylinder 5 rises. That is, when the user rotates the outer cylinder 8 with respect to the housing cylinder 4, the first intermediate cylinder 5 moves up and down without relative rotation with respect to the housing cylinder 4.
[0035] FIG. 5 shows the state after the outer cylinder 8 is rotated once from the bottom dead center state of the feeding container 100 shown in FIG. 3. Further, FIG. 6 shows the top dead center state of the feeding container 100 after the outer cylinder 8 is further rotated from the state of FIG. 5.
[0036] As shown in FIG. 5, the first intermediate cylinder 5 has risen with respect to the outer cylinder 8. Although the inner cylinder 6 is accommodated in the first intermediate cylinder 5, since the circumferential rib 62 at the upper end of the inner cylinder 6 is disposed on the circumferential convex portion 56 of the first intermediate cylinder 5, the inner cylinder 6 accommodated in the first intermediate cylinder 5 also rises as the first intermediate cylinder 5 rises. Then, as the inner cylinder 6 rises, the screw shaft 3b having the external thread 32 engaged with the inner cylinder internal thread 64 of the inner cylinder 6 rises, and thus the rod-shaped material holding portion 3 rises.
[0037] Further, when the user rotates the outer cylinder 8 relative to the housing cylinder 4, the second intermediate cylinder 7 fixed to the outer cylinder 8 also rotates. The second intermediate cylinder 7 is provided with a flange 72 formed at its lower end, and since the notch 72c of the flange 72 is fitted with the lower end surface projection 85 of the outer cylinder 8, as described above, the outer cylinder 8 and the second intermediate cylinder 7 are relatively non-rotatable and relatively non-vertically movable. Therefore, when the user rotates the outer cylinder 8 relative to the housing cylinder 4, the second intermediate cylinder 7 relatively rotates with respect to the housing cylinder 4 without moving vertically. And when the second intermediate cylinder 7 rotates, the inner cylinder 6 engaged with the second intermediate cylinder 7 also rotates integrally. That is, the inner cylinder 6 rotates with respect to the first intermediate cylinder 5 within the first intermediate cylinder 5.
[0038] The external thread 32 of the screw shaft 3b of the rod holding portion 3 is screwed into the internal thread 64 inside the inner cylinder 6 formed on the inner peripheral surface of the inner cylinder 6. And since the screw shaft 3b is non-rotatable with respect to the first intermediate cylinder 5 as described above, when the inner cylinder 6 rotates with respect to the first intermediate cylinder 5, the screw shaft 3b rises, and thus the rod holding portion 3 rises.
[0039] In this way, when the user rotates the outer cylinder 8 relative to the housing cylinder 4, the inner cylinder 6 relatively rises with respect to the housing cylinder 4 via the first intermediate cylinder 5, and the inner cylinder 6 relatively rotates with respect to the housing cylinder 4 via the second intermediate cylinder 7. That is, due to the rotation of the outer cylinder 8, the inner cylinder 6 rises via the first intermediate cylinder 5 and rotates via the second intermediate cylinder 7 at the same time. According to this embodiment, not only can the inner cylinder 6 simply rotate or rise due to the rotation of the outer cylinder 8, but it can rotate while rising, so that a longer feeding length can be obtained with a small rotational movement of the outer cylinder 8 or with less labor.
[0040] More specifically, when the inner cylinder 6 itself ascends, the lifting stroke of the screw shaft 3b can be obtained, and also when the inner cylinder 6 rotates, the lifting stroke of the screw shaft 3b engaged with the inner cylinder 6 can be obtained. If the former lifting stroke, that is, the lifting stroke due to the ascent of the inner cylinder 6 itself (the lifting stroke resulting from the function of the first intermediate cylinder 5) is Δh5, and the latter lifting stroke, that is, the lifting stroke due to the rotation of the inner cylinder 6 (the lifting stroke resulting from the function of the second intermediate cylinder 7) is Δh7, then the lifting stroke (total stroke) of the screw shaft 3b (or the rod holding portion 3) is Δh t Then, Δh t = Δh5 + Δh7.
[0041] Also, according to this embodiment, the first intermediate cylinder 5, the second intermediate cylinder 7, and the inner cylinder 6 included in the intermediate mechanism are housed below the lower end of the receiving portion 3a of the rod holding portion 3, and the intermediate mechanism that occupies a large part of the feeding mechanism is compactly configured. On the other hand, as described above, the outer cylinder 8 is formed long with respect to the intermediate mechanism, and in the bottom dead center state, the upper end of the internal thread 82 in the outer cylinder is located above the lower end of the bottom surface of the receiving portion 3a, so the feeding length of the rod can be increased. Therefore, in the entire feeding container having the same overall length as the conventional one, the feeding length of the rod can be increased without distributing the accommodation space of the rod to the accommodation space of the intermediate mechanism. Therefore, as shown in FIG. 6, the rod 1 can be lifted and fed until the middle dish 2 for accommodating the rod 1 is exposed.
[0042] Each member of the rod feeding container 100 may be formed of resin or metal. Examples of the resin include AS (acrylonitrile-styrene), ABS (acrylonitrile-butadiene-styrene), PP (polypropylene), POM (polyacetal), UHMWPE (ultra-high molecular weight polyethylene), etc., and engineering plastics can also be used. Also, if it is metal, aluminum or the like can be used.
