[0006] [Patent Document 1] Japanese Utility Model Application Publication No. 59-013218 [Patent Document 2] Utility Model Registration No. 3089979 [Patent Document 3] Utility Model Registration No. 3127399 Summary of the Invention [Problem to be solved by the invention]
[0007] The present invention aims to provide a new pen-type container that can replace a used bottle. [Means for solving the problem]
[0008] In order to solve the above problems, the present invention is configured as follows. That is, the pen-type container according to the present invention may have a pen body that is held by a user during use, and a first replacement bottle that is detachably attached to the pen body. The first replacement bottle may have a cylindrical body and a discharge port provided at one end of the body. The body may have an engagement portion on its outer periphery near the one end. The pen body may have a first movement restricting portion that engages with the engagement portion of the body so as to be immovable in the axial direction, and a first exterior portion that extends from the first movement restricting portion to the other end side of the body and covers the outer periphery of the body.
[0009] In this way, the engagement portion of the body and the first movement restricting portion are engaged near the one end side, so that the discharge port is less likely to be displaced in the axial direction when the user tries to discharge the contents while holding the pen body. As a result, the contents stored in the first replacement bottle can be stably discharged from the discharge port while the user is holding the pen body. Furthermore, since the first replacement bottle is supported by the pen body at the engagement portion located near the discharge port, even if an external force is applied to a discharge device such as an applicator or spray device attached to the discharge port in a direction intersecting the axial direction during use, the moment generated in the support part by the external force is reduced, and a more stable discharge operation can be performed. In addition, the first exterior part of the pen body covers the outer periphery of the body of the replacement bottle, so that the design of the pen-type container as a whole can be improved by the first exterior part. Note that the first exterior part may cover the outer periphery of the body over the entire circumference, or may cover a part of the circumference.
[0010] The outer peripheral surface of the body may be supported by the inner peripheral surface of the first exterior part at least on the other end side of the engaging part. This allows the outer peripheral surface of the body to be supported at least at two points, the first movement restricting part and the other end side of the engaging part. As a result, the axis of the pen body and the discharge port is less likely to shift, and the content contained in the first replacement bottle can be discharged more stably from the discharge port while the pen body is held by a user. Note that the entire inner peripheral surface of the first exterior part may be in contact with or close to the outer peripheral surface of the body, or a part of the inner peripheral surface of the first exterior part may be in contact with or close to the outer peripheral surface of the body.
[0011] The first movement restricting portion may be engaged with the engaging portion so as to prevent rotation of the first replacement bottle relative to the pen body. This makes it difficult for the discharge port to rotate. As a result, the content contained in the first replacement bottle can be discharged more stably from the discharge port while the pen body is being held by a user.
[0012] The pen-type container may further include a second replacement bottle detachably attached to the pen body. The second replacement bottle may have a cylindrical body and an outlet provided at one end of the body. The body of the second replacement bottle may have an engagement portion on the outer periphery near the one end side. The first and second replacement bottles may be attached to the pen body such that their other end faces face each other and their outlets face in opposite directions. The pen body may further include a second movement restricting portion that engages with the engagement portion of the body of the second replacement bottle so as to be immovable in the axial direction, and a second exterior portion that extends from the second movement restricting portion to the other end side of the body of the second replacement bottle and covers the outer periphery of the body of the second replacement bottle.
[0013] In this way, the engaging portion of the barrel of the second replacement bottle and the second movement restricting portion are engaged near the one end side, so that the content accommodated in the second replacement bottle can be stably discharged from the discharge port while the user is holding the pen body in the second replacement bottle. In addition, since the first replacement bottle and the second replacement bottle are connected by the pen body, the content accommodated in the first replacement bottle and the second replacement bottle can be discharged from their discharge ports, respectively. As a result, the pen-type container can discharge two different types of content, and the user's convenience can be improved by changing the content according to the user's preference. In addition, since only one of the first and second replacement bottles can be replaced, there is no need to discard the replacement bottle with the remaining content.
[0014] The second movement restricting portion may be engaged with the engaging portion so as to prevent rotation of the second replacement bottle relative to the pen body. This makes it difficult for the discharge port of the second replacement bottle to rotate. As a result, the content contained in the second replacement bottle can be more stably discharged from the discharge port while the pen body is being held by a user.
[0015] The body of the first replacement bottle may be configured in a cylindrical shape. The pen body may be a long member having a C-shaped cross section and a slit for radially extracting the first replacement bottle in a circumferential portion. The width of the slit may be narrower than the diameter of the body of the first replacement bottle. The pen body may be elastically deformable so that the width of the slit becomes larger than the diameter of the body of the first replacement bottle when the first replacement bottle is extracted. This allows the pen body and the first replacement bottle to be easily attached and detached.
[0016] The pen body may be a long member having a C-shaped cross section and a slit for radially extracting the second replacement bottle in a circumferential portion. The width of the slit may be narrower than the diameter of the body of the second replacement bottle. The pen body may be elastically deformable so that the width of the slit becomes larger than the diameter of the body of the second replacement bottle when the second replacement bottle is extracted. This allows the pen body and the second replacement bottle to be easily attached and detached. The slit for the first replacement bottle and the slit for the second replacement bottle may be configured as a single slit that is continuous in the axial direction. When the diameters of the body of the first and second replacement bottles are different, the width of each slit can be set according to the diameter of the corresponding bottle.
[0017] The pen body may be cylindrically configured from first and second divided members that are separable in the radial direction. This allows the first replacement bottle (or the first and second replacement bottles, if a second replacement bottle is present) to be attached by being sandwiched between the first divided member and the second divided member, and allows the first replacement bottle to be easily attached and detached from the pen body even though the entire circumference of the first replacement bottle is covered by the first and second divided members.
[0018] The first movement restricting portion may be composed of a first locking piece provided on the first divided member and a second locking piece provided on the second divided member. The first locking piece may be releasably engaged with the engaging portion of the body in one radial direction. The second locking piece may be releasably engaged with the engaging portion of the body in the opposite direction. This allows each divided member to be engaged with the engaging portion of the body of the first replacement bottle, thereby more stably supporting the first replacement bottle.
[0019] Furthermore, the first and second locking pieces may be configured to engage with each other to prevent separation in the radial direction, and to be disengaged by elastic deformation of the locking pieces. This makes it possible to lock the first and second divided members together and to prevent the first and second divided members from unintentionally separating when the pen-shaped container is in use.
[0020] The first exterior part may be composed of a first semi-cylindrical part provided on the first divided member and a second semi-cylindrical part provided on the second divided member. The outer peripheral surface of the body part may be supported from both radial sides by the inner peripheral surfaces of the first and second semi-cylindrical parts. This makes it possible to prevent the body part and the first exterior part from being displaced radially or from swinging about the engagement part as a fulcrum. As a result, the contents can be more stably discharged from the discharge port while the pen body is held by a user. Effect of the Invention
[0021] According to the present invention, a new pen-type container that can replace a used bottle can be provided. [Brief description of the drawings]

[Figure 6] FIG. 6 is an external perspective view showing the structure of a pen-type container according to another embodiment. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0023] (First embodiment) The pen-type container 1 according to the first embodiment will be specifically described below with reference to Figures 1 to 4. As shown in Figures 1 and 2, the pen-type container 1 includes a replacement bottle 2, a replacement bottle 3, a cap 4, a cap 5, and a pen body 6.
[0024] As shown in FIG. 2, the replacement bottle 2 has a cylindrical body 21 and a discharge port 22 formed continuously at one end of the body 21 and communicating with the body 21 in an internal space. The body 21 accommodates contents such as a liquid medicine in its internal space. The body 21 has an engagement portion 211 on the outer periphery near the one end side. The engagement portion 211 is formed by cutting out the outer periphery of the body 21 in a flat shape. The engagement portion 211 has a flat portion 211a and step portions 211b, 211b formed at both axial ends of the flat portion 211a. That is, by cutting out the outer periphery of the replacement bottle 2, a step is formed between the outer periphery of the replacement bottle 2 and the flat portion 211a. The engagement portion 211 engages with a movement restriction portion 61 of the pen body 6 described later in the axial direction, thereby making it impossible for the replacement bottle 2 to move in the axial direction relative to the pen body 6. The body 21 is not limited to a cylindrical shape, and may be an elliptical cylindrical shape or a polygonal cylindrical shape. When body portion 21 is a polygonal tube, the corners of the polygon in cross section may be cut out flat, or the flat outer surface of body portion 21 may be cut out to form engagement portion 211.
[0025] The discharge port 22 refers to a portion of the replacement bottle 2 that is closer to one end than the body portion 21. With reference to Figs. 2 and 4, the discharge port 22 is formed continuously from the body portion 21 and includes a tubular portion having a male thread for screwing with the cap 4 and a discharge portion including a spring. The discharge port 22 discharges the contents contained in the internal space of the replacement bottle 2 to the outside in the axial direction (upward in the figure). For example, since the discharge port 22 in this embodiment is a so-called spring plug, the contents can be discharged by pressing the tip of the discharge port 22 from which the contents are discharged against the application part such as the user's skin or scalp.
[0026] The discharge port 22 is not limited to the above, and is not particularly limited as long as it can discharge the contents of the replacement bottle 2. For example, the outer peripheral surface of the body 21 of the replacement bottle 2, which is elastically deformable in the radial direction, may be pressed from the outside to the inside in the radial direction to discharge the contents of the replacement bottle 2 from the discharge port 22. In this case, the pen body 6 may also be configured to be elastically deformable in the radial direction so that the replacement bottle 2 can be pressed, or a through hole may be provided in the pen body 6 so that the user's finger can be inserted through the through hole to directly press the replacement bottle 2. Also, for example, mascara may be stored in the replacement bottle 2, and a brush attached to the cap 4 may be taken out from the discharge port 22, or lipstick attached to the cap 4 may be stored in the internal space of the replacement bottle 2, and the lipstick may be taken out from the discharge port 22. Also, ink may be stored in the body 21, and a ball of a ballpoint pen or a pen tip of a marking pen (highlighter) may be attached to the discharge port 22. Furthermore, a stick-shaped tool such as a cotton swab or a toothpick may be stored in the replacement bottle 2, and the stick-shaped tool may be removed from the replacement bottle 2 when in use. In this way, the pen-type container 1 can be used not only as a pen, but also in various other ways depending on the contents stored in the replacement bottle 2 and the replacement bottle 3. The same applies to the discharge port 32 of the replacement bottle 3, which will be described later.
[0027] The replacement bottle 3 has a cylindrical body 31 and a discharge port 32 formed continuously at one end of the body 31 and communicating with the body 31 through an internal space. The body 31 accommodates contents such as a liquid medicine in its internal space. The body 31 has an engagement portion 311 on the outer periphery near the one end side. The engagement portion 311 is formed by cutting out the outer periphery of the body 31 in a flat shape. The engagement portion 311 has a flat portion 311a and step portions 311b, 311b formed at both axial ends of the flat portion 311a. That is, by cutting out the outer periphery of the replacement bottle 3, a step is formed between the outer periphery of the replacement bottle 3 and the flat portion 311a. The step portion 311b engages with a movement restriction portion 63 of the pen body 6 described later in the axial direction, thereby making it impossible for the replacement bottle 3 to move in the axial direction relative to the pen body 6. The body 31 is not limited to a cylindrical shape, and may be an elliptical cylindrical shape or a polygonal cylindrical shape. In the case of the body 31 having a polygonal cylindrical shape, the corners of the polygonal shape in cross section may be cut out in a flat shape, or the flat outer surface of the body 31 may be cut out to form the engagement portion 211. The other end face (bottom face) of the replacement bottle 3 faces the other end face (bottom face) of the replacement bottle 2. The replacement bottles 2 and 3 are attached to the pen body 6 so that the discharge ports 22 and 32 of the replacement bottle 2 and 3 face in opposite directions. The axial length of the body 21 of the replacement bottle 2 and the axial length of the body 31 of the replacement bottle 3 are substantially the same in the drawings, but can be appropriately changed depending on the type of contents to be contained in the body 21 and the body 31. For example, when contents with a small amount of content and contents with a large amount of content are contained in the body 21 and the body 31, respectively, the axial length of one of the body 21 and the body 31 may be made smaller to contain the contents with a small amount of content, and the axial length of the other body 21 and the body 31 may be made larger to contain the contents with a large amount of content.
[0028] The discharge port 32 refers to a portion of the replacement bottle 3 that is closer to one end than the body portion 31. It discharges the contents contained in the internal space of the body portion 31 outward in the axial direction (downward in the figure). For example, the discharge port 32 is a spray device that sprays the contents from the body portion 31 outward in the radial direction by pushing the tip of the discharge port 32 inward in the axial direction.
[0029] The cap 4 is attached on the axially outer side (upper side in the figure) of the replacement bottle 2 so as to cover the discharge port 22 .
[0030] The cap 5 is attached axially outward (lower in the drawing) than the replacement bottle 3 so as to cover the discharge port 32. Note that the caps 4 and 5 are not particularly limited as long as they can cover the discharge port 22 and the discharge port 32.
[0031] The pen body 6 is held by a user when using the pen-type container 1. The pen body 6 has a movement restricting portion 61, an exterior portion 62, a movement restricting portion 63, and an exterior portion 64. The movement restricting portion 61 engages with the engagement portion 211 of the body portion 21 so as to be immovable in the axial direction. The exterior portion 62 has a semicircular shape in cross section, and extends from the movement restricting portion 61 to the other end side of the body portion 21 to cover the outer periphery of the body portion 21. The movement restricting portion 63 engages with the engagement portion 311 of the body portion 31 so as to be immovable in the axial direction. The exterior portion 64 has a semicircular shape in cross section, and extends from the movement restricting portion 63 to the other end side of the body portion 31 of the exchange bottle 3 to cover the outer periphery of the body portion 31 of the exchange bottle 3. As shown in the figure, the exterior portion 62 and the exterior portion 64 are continuously and integrally formed. In this way, the exterior parts 62 and 64 are formed in a cylindrical shape, but are not limited thereto, and may be formed in an elliptical cylindrical shape or a polygonal cylindrical shape depending on the shapes of the body part 21 of the replacement bottle 2 and the body part 31 of the replacement bottle 3 described above. The exterior part 62 may cover the outer periphery of the body part 21 over the entire circumference, or may cover only a part of the circumference. The exterior part 64 may cover the outer periphery of the body part 31 over the entire circumference, or may cover only a part of the circumference. The relationship between the movement restricting part 61 and the engagement part 211 will be described later with reference to Figs. 3 and 4.
[0032] The pen body 6 is composed of a divided member 6a and a divided member 6b that can be separated in the radial direction. The exterior part 62 has a semi-cylinder part 62a provided in the divided member 6a and a semi-cylinder part 62b provided in the divided member 6b. The exterior part 64 has a semi-cylinder part 64a provided in the divided member 6a and a semi-cylinder part 64b provided in the divided member 6b. The outer peripheral surface of the body part 21 is supported from both sides in the radial direction by the inner peripheral surfaces of the semi-cylinder part 62a and the semi-cylinder part 62b. The outer peripheral surface of the body part 31 is supported from both sides in the radial direction by the inner peripheral surfaces of the semi-cylinder part 64a and the semi-cylinder part 64b. This makes it possible to suppress the body part 21 and the exterior part 62 from being displaced in the radial direction or from swinging around the engagement part 211 as a fulcrum. As a result, the contents can be stably discharged from the discharge port 22 while the pen body 6 is held by the user. Similarly, the contents can be stably discharged from the discharge port 32 in the body 31 and the exterior 64. Although the divided members 6a and 6b are separated in the radial direction in Fig. 2, the replacement bottles 2 and 3 may be attached inside the pen body 6 by connecting one end side of each of the opposing members with a hinge or the like and rotating the divided members 6a and 6b in the radial direction around the hinge as an axis to open and close the other end sides of each of the opposing members.
[0033] The outer peripheral surface of the body 21 is supported by the inner peripheral surface of the exterior part 62 at least on the other end side (bottom side of the replacement bottle 2) from the engaging part 211. The outer peripheral surface of the body 31 is supported by the inner peripheral surface of the exterior part 64 at least on the other end side (bottom side of the replacement bottle 3) from the engaging part 311. That is, the outer peripheral surfaces of the body 21 and the body 31 are supported by the inner peripheral surfaces of the exterior parts 62 and 64 at the engaging parts 211 and 311 and at least two points on the other end side of each. This makes it difficult for the axes of the discharge port 22 and the discharge port 32 to shift relative to the pen body 6, so that the contents of the replacement bottle 2 and the replacement bottle 3 can be discharged stably. The entire inner peripheral surface of the exterior part 62 may be in contact with or close to the outer peripheral surface of the body 21, or a part of the inner peripheral surface of the exterior part 62 may be in contact with or close to the outer peripheral surface of the body 21. In addition, the entire inner surface of the exterior portion 64 may be in contact with or close to the outer surface of the body portion 31, or only a portion of the inner surface of the exterior portion 64 may be in contact with or close to the outer surface of the body portion 31.
[0034] As shown in FIG. 3, the movement restricting portion 61 is formed in a protruding shape toward the circumferentially inner side in correspondence with the engagement portion 211, which is a flat cutout of the outer peripheral surface of the body 21. The movement restricting portion 61 has a rotation restricting surface 61a that faces the flat portion 211a of the engagement portion 211 in the radial direction, and axial movement restricting surfaces 61b, 61b that face each of the step portions 211b, 211b of the engagement portion 211. As shown in FIG. 3 and FIG. 4, the rotation restricting surface 61a comes into contact with the flat portion 211a when the body 21 tries to rotate relative to the pen body 6. That is, the rotation restricting surface 61a includes a flat contact surface that faces the flat portion 211a. This makes it possible to prevent the body 21 from rotating relative to the pen body 6.
[0035] The axial movement restricting surfaces 61b, 61b are an end surface on one end side (upper side in the figure) of the movement restricting portion 61 formed in a protruding shape toward the circumferential inside, and an end surface on the other end side (lower side in the figure) of the movement restricting portion 61. The axial movement restricting surfaces 61b, 61b are in axial contact with the step portions 211b, 211b of the engagement portion 211, respectively. This allows the movement restricting portion 61 to disable the body portion 21 from moving in the axial direction relative to the pen body 6. In this way, the movement restricting portion 61 engages with the engagement portion 211, thereby preventing the body portion 21 from rotating and moving in the axial direction relative to the pen body 6, and as a result, the contents accommodated in the replacement bottle 2 can be stably discharged from the discharge port 22 while the pen body 6 is held by the user. As shown in FIGS. 1 to 4, in this embodiment, the engagement portion 211 and the movement restricting portion 61 are formed in pairs at positions facing each other on the outer circumferential surface of the body portion 21. The configuration of the engagement portion 311 and the movement restriction portion 63 of the exchange bottle 3 is the same as the configuration of the engagement portion 211 and the movement restriction portion 61 of the exchange bottle 2. Therefore, detailed description of the engagement portion 311 and the movement restriction portion 63 of the exchange bottle 3 is omitted. The bottom surface of the exchange bottle 2 and the bottom surface of the exchange bottle 3 are flat as shown in FIG. 3, but are not limited to this. For example, a recess may be provided on one of the bottom surfaces of the exchange bottle 2 and the bottom surface of the exchange bottle 3, and a protrusion having a shape corresponding to the recess may be provided on the other bottom surface. The recess may be mortar-shaped, and the protrusion may be conical-shaped corresponding to the mortar shape. As a result, the recess provided on one of the bottom surfaces of the exchange bottle 2 and the bottom surface of the exchange bottle 3 engages with the protrusion provided on the other, and the exchange bottle 2 and the exchange bottle 3 can be connected while suppressing radial displacement from each other. Furthermore, by connecting replacement bottle 2 and replacement bottle 3 in this manner and engaging portions 211 and 311 provided on one end of each bottle with movement regulating portions 61 and 63, rotation and axial movement of body portion 21 and body portion 31 can be more reliably prevented.
[0036] In FIG. 3, the cylindrical body 21 and the tubular portion of the outlet 22 on which the male thread is formed are integrally formed. In this case, the replacement bottle 2 is replaced as a whole. The cap 4 may also be replaced. As described above, the contents contained in the replacement bottle 2 are various, and the configurations of the outlet 22 and the cap 4 differ depending on the type of contents. Therefore, when the body 21 and the outlet 22 are configured to be detachable, only the body 21 that contains the contents may be replaced. That is, at least the body 21 may be replaced. The same applies to the body 31 and the outlet 32 of the replacement bottle 3, and the cap 5.
[0037] As shown in FIG. 4, the movement restricting portion 61 can be separated near the center in the circumferential direction (the vertical direction in the figure). That is, the movement restricting portion 61 is composed of the movement restricting portion 61 on the circumferential end side of the divided member 6a and the movement restricting portion 61 on the circumferential end side of the divided member 6b. The movement restricting portion 61 has a locking piece 611 and a locking piece 612. The locking piece 611 is provided at both ends in the circumferential direction of the divided member 6a. The locking piece 612 is provided at both ends in the circumferential direction of the divided member 6b. As shown in the figure, the outer surface of one of the locking pieces 611 and 612 has a gentle protrusion, and the inner surface of the other has a gentle groove at a position corresponding to the protrusion. The divided members 6a and 6b are integrated to form the pen body 6 by engaging the protrusion of one of the locking pieces 611 and 612 with the groove of the other. That is, the locking pieces 611 and 612 are engaged to prevent separation in the radial direction, suppressing separation of the divided member 6b from the divided member 6a, and are configured to be disengaged by elastic deformation of the locking pieces 611 and 612. The locking pieces 611 are engaged with the engaging portion 211 of the body 21 in one radial direction so as to be disengaged. The locking pieces 612 are engaged with the engaging portion 211 of the body 21 in the opposite direction to the locking pieces 611 so as to be disengaged. That is, the pen body 6 is formed to be detachable from the body 21 by sliding the inner surfaces (rotation restriction surfaces 61a) of the locking pieces 611 and 612 along the flat surface portion 211a of the engaging portion 211 in the radial direction. The configurations of the engaging portion 311 and the movement restriction portion 63 of the exchange bottle 3 are similar to those of the engaging portion 211 and the movement restriction portion 61 of the exchange bottle 2. Therefore, a description of the locking pieces of the movement restriction portion 63 will be omitted. In this way, the pen body 6 is detachably provided on the replacement bottle 2 and the replacement bottle 3, and stores the replacement bottle 2 and the replacement bottle 3 therein. The replacement bottle 2 and the replacement bottle 3 are connected by the pen body 6 with the other end faces (bottom faces) of the replacement bottles 2 and 3 facing each other, i.e., with the discharge outlet 22 and the discharge outlet 32 facing in opposite directions.
[0038] The locking piece 611 has a pressing portion 611a. The locking piece 612 has a pressing portion 612a. As shown in FIG. 4, the outer peripheral surface of the movement restricting portion 61 is formed in a concave shape. The pressing portion 612a and the pressing portion 612b are wall surfaces along the axial direction in the concave shape. When separating the divided member 6a and the divided member 6b, the user presses the pressing portion 611a with his / her finger in one radial direction and presses the pressing portion 612b with his / her finger in the opposite direction. This makes it possible to easily separate the divided member 6a and the divided member 6b, and to easily replace the used replacement bottle 2. The pressing portion 611a and the pressing portion 612b may be side surfaces of protrusions provided on the outer peripheral surfaces of the locking piece 611 and the locking piece 612. The same applies to the movement restricting portion 63.
[0039] In this way, according to the pen-type container 1, the contents can be stably discharged from the discharge ports 22, 32, and various contents can be stored in the replacement bottle 2 and the replacement bottle 3 connected by the pen body 6, so that the replacement bottle 2 and the replacement bottle 3 can be used according to the user's preferences. In addition, since the body 21 and the body 31 of the replacement bottle 2 and the replacement bottle 3 are covered by the pen body 6, the design of the pen-type container 1 as a whole can be improved by, for example, decorating the outer peripheral surface of the pen body 6. In addition, the pen body 6 can suppress damage to the replacement bottle 2 and the replacement bottle 3. Furthermore, since only one of the replacement bottle 2 or the replacement bottle 3 can be replaced, there is no need to discard either the replacement bottle 2 or the replacement bottle 3 in which the contents remain.
[0040] In addition, since the pen body 6 is composed of a dividing member 6a and a dividing member 6b that can be separated radially, the entire circumference of the replacement bottle 2 or replacement bottle 3 is covered by the pen body 6, yet the replacement bottle 2 or replacement bottle 3 can be easily attached and detached from the pen body 6.
[0041] Second embodiment Next, the pen-type container 1 of the second embodiment will be specifically described with reference to Fig. 5. Basically, the description of the same configuration as the pen-type container 1 of the first embodiment will be omitted, and only the configuration different from the pen-type container 1 of the first embodiment will be described.
[0042] As shown in FIG. 5, the pen-type container 1 is different from the pen-type container 1 of the first embodiment in that the replacement bottle 3 is not configured. The pen-type container 1 has one replacement bottle 2. The pen body 6 is detachably attached to the outer periphery of the replacement bottle 2. The engagement portion 311 is formed by cutting out the outer periphery of the other end side (bottom surface side) of the replacement bottle 2. The engagement portion 311 is formed only with a step portion 311b on one end side (discharge port 22 side), and the step portion 311b is not formed on the other end side. The movement restriction portion 63 has a bottom portion 65. The inner surface of the bottom portion 65 contacts the bottom surface of the replacement bottle 2. This makes it possible to disable the replacement bottle 2 from moving in the axial direction (downward in the figure).
[0043] Third embodiment Next, the pen-type container 1 of the third embodiment will be specifically described with reference to Fig. 6. Basically, the description of the same configuration as the pen-type container 1 of the first embodiment will be omitted, and only the configuration different from the pen-type container 1 of the first embodiment will be described.
[0044] As shown in FIG. 6, the pen-type container 1 differs from the pen-type container 1 of the first embodiment only in the configuration of the pen body 6. That is, the pen body 6 of this embodiment is a long member having a C-shaped cross section. The pen body 6 has a slit 66 for radially extracting the replacement bottle 2 and the replacement bottle 3 in a part of the circumferential direction. The movement restricting portion 61 and the movement restricting portion 63 are formed at both ends of the C-shaped cross section and at both ends of the axial direction of the pen body 6. The width of the slit 66 is narrower than the diameter (outer diameter) of the body 21 and the body 31 of the replacement bottle 2 and the replacement bottle 3, and the pen body 6 is elastically deformable so that the width of the slit 66 becomes larger than the diameter of the body 21 and the body 31 when the replacement bottle 2 and the replacement bottle 3 are extracted. This allows the replacement bottle 2 and the replacement bottle 3 to be extracted from the pen body 6. On the other hand, when the replacement bottle 2 and the replacement bottle 3 are pushed in through the slit 66, both ends of the C-shaped cross section of the pen body 6 are bent radially outward. Then, by further pushing in, the replacement bottle 2 and the replacement bottle 3 can be easily attached to the pen body 6. In this embodiment, the slit 66 for the replacement bottle 2 and the slit 66 for the replacement bottle 3 are configured as a single slit 66 that is continuous in the axial direction, but they may be configured to be offset from each other in the circumferential direction. In addition, when the diameters of the body 21 of the replacement bottle 2 and the body 31 of the replacement bottle 3 are different, the widths of the respective slits 66 may be set according to the diameters of the corresponding bottles. In addition, the pen body 6 having a C-shaped cross section can also be applied to one replacement bottle 2 as in the second embodiment.
[0045] Although the embodiments have been described above, the present disclosure is not limited to the above-described embodiments, and various modifications are possible without departing from the spirit of the present disclosure. [Explanation of symbols]
