Embodiments of the present invention will be exemplified below with reference to the drawings.

As shown in FIGS. 1 to 4, in the first embodiment of the present invention, a feeding container 1 has a case cylinder 2, a feeding member 3, an operating member 4 and a cap 5. As shown in FIGS. The case tube 2 has a body tube 6 and a split nut portion 7 . The delivery member 3 has a male threaded cylinder 8 and a middle plate 9 . The operating member 4 has an engaging shaft 10 , an operated portion 11 and an inner cylindrical portion 12 . The inner cylindrical portion 12 has a restricting portion 13 . The inner tubular portion 12 and the main tubular portion 6 are engaged with each other via the rotary connecting portion 14 and the ratchet portion 15 . The cap 5 has an insert 16 and a body portion 17 . The case cylinder 2, the feeding member 3, the operating member 4 and the cap 5 are each integrally molded.

For convenience of explanation, the direction along the central axis O with the cap 5 closed will be referred to as the axial direction or the vertical direction, and the direction along the central axis O from the male threaded cylinder 8 toward the inner plate 9 will be referred to as the upward direction. The opposite direction is also called downward, the direction along a straight line perpendicular to the central axis O is also called the radial direction, the direction around the central axis O is also called the circumferential direction, and the cross section including the central axis O is also called the longitudinal section.

The main body tube 6 of the case tube 2 has a cylindrical shape centered on the central axis O, and the upper tube end forms a delivery port 18 . Note that the delivery port 18 is not limited to the configuration in which it is inclined with respect to the horizontal plane as illustrated. The outer peripheral surface of the main body tube 6 has a diameter-reduced portion 6a whose diameter is reduced stepwise on the upper side.

The cap 5 has a cylindrical outer peripheral wall 5a centered on the central axis O, and a ceiling wall 5b closing the upper end of the outer peripheral wall 5a. The cap 5 is composed of a capped cylindrical insert member 16 made of a soft material that forms the inner surface of the upper portion of the cap 5, and a capped cylindrical main body that covers the outer surface of the insert member 16 and extends below the insert member 16. It is an insert-molded product formed by the part 17 . By fitting the outer peripheral wall 5a of the cap 5 over the diameter-reduced portion 6a of the main body cylinder 6, the soft insert member 16 of the cap 5 is brought into close contact with the diameter-reduced portion 6a, thereby sealing the feeding port 18. As shown in FIG. The cap 5 is configured to be detachable from the reduced-diameter portion 6a so that the feeding port 18 can be opened and closed. With such a configuration of the cap 5, good airtightness of the feeding port 18 can be realized.

The split nut portion 7 of the case tube 2 extends downward in a radially inward direction from the inner peripheral surface of the main tube 6, and has split portions 7a that are split in the circumferential direction at four locations. , and has a threaded portion 7b at the lower end of the inner peripheral surface. The split nut portion 7 is not limited to the configuration in which the divided portions 7a are provided at four locations in the circumferential direction as shown in the figure, and may be configured to have the divided portions 7a at one or more locations in the circumferential direction. Since the split nut portion 7 has the dividing portion 7a, it can be easily displaced radially outward by elastic deformation.

An inner plate 9 is fitted to a portion of the inner peripheral surface of the main body tube 6 of the case tube 2 above the split nut portion 7 so as to be slidable upward. Inside the body tube 6, a storage portion S for the contents C is formed between the delivery port 18 and the inner plate 9. In the storage portion S, the inner peripheral surface of the body tube 6 is formed inside a cylinder having a constant inner diameter in the vertical direction. form a circumference. The middle plate 9 has a circular shape when viewed from the top, and has a close contact tube 9a on the outer peripheral edge. The tight contact tube 9a has a constricted cylindrical shape that is in close contact with the inner peripheral surface of the main body tube 6 at the upper end and the lower end over the entire circumference, and separated from the inner peripheral surface of the main body tube 6 at the vertical middle part.

The content C is solid, semi-solid or liquid, and is contained in the container S. The type of the content C is not particularly limited, and may be, for example, cosmetics such as lipstick or lip balm, medicines, glue, or the like.

The male threaded cylinder 8 has a male threaded portion 8a on its outer peripheral surface that is screwed into the threaded portion 7b, and has a hollow screw shaft shape centered on the central axis O. As shown in FIG. The male threaded tube 8 rotates in the first circumferential direction with respect to the case tube 2 (the threaded portion 7b and the main body tube 6) in a state where the male threaded portion 8a is screwed to the threaded portion 7b. can be lifted integrally with the inner plate 9. The male screw cylinder 8 is integrally provided with the middle plate 9 and extends downward from the middle plate 9 .

The engaging shaft 10 of the operating member 4 is engaged with the inner peripheral surface of the male threaded cylinder 8 so as to be axially slidable and circumferentially corotatable. More specifically, the engagement shaft 10 has a cross-shaped spline shaft shape when viewed from above, and the inner peripheral surface of the male threaded cylinder 8 has a complementary shape to the engagement shaft 10 . The shape of the outer peripheral surface of the engaging shaft 10 and the inner peripheral surface of the male threaded cylinder 8 is not limited to this. Any shape may be used as long as it allows engagement.

The upper end of the engaging shaft 10 is located above the upper end of the male threaded portion 8a. The lower end of the male screw portion 8a is located below the lower end of the case tube 2. As shown in FIG.

The operated portion 11 of the operating member 4 is arranged below the case tube 2 and can receive a rotation operation for rotating the operated portion 11 in the circumferential direction with respect to the case tube 2 . Further, the operated portion 11 has a bottom wall 11a integrally connected to the lower end portion of the engaging shaft 10 and an outer peripheral portion 11b extending upward from the outer peripheral edge portion of the bottom wall 11a. The upper end surface of the outer peripheral portion 11 b faces the lower end surface of the case cylinder 2 .

The inner cylindrical portion 12 of the operating member 4 has a cylindrical shape centered on the central axis O, and is integrally connected to the upper end of the outer peripheral portion 11b of the operated portion 11 at its lower end. The inner tube portion 12 is arranged radially inward of the main tube 6 . That is, the outer peripheral surface of the inner tubular portion 12 faces the inner peripheral surface of the main tube 6 .

The outer peripheral surface of the inner cylinder portion 12 and the inner peripheral surface of the main body cylinder 6 are engaged with each other via the rotary connecting portion 14 . The rotary connecting portion 14 includes a circumferential groove provided on one of the inner peripheral surface of the main tube 6 and the outer peripheral surface of the inner tube portion 12 and extending in the circumferential direction, and the inner peripheral surface of the main tube 6 and the outer peripheral surface of the inner tube portion 12 . and a convex portion which is provided on the other side and fitted into the circumferential groove, and holds the inner cylinder portion 12 and the operated portion 11 in the main cylinder 6 so as to be rotatable in the circumferential direction. Therefore, the operated portion 11 is held by the case tube 2 so as to be rotatable in the circumferential direction with respect to the case tube 2 integrally with the inner tube portion 12 and the engaging shaft 10 .

The outer peripheral surface of the inner cylinder portion 12 and the inner peripheral surface of the main body cylinder 6 are engaged via the ratchet portion 15 . The ratchet portion 15 allows rotation of the inner cylinder portion 12, the operated portion 11 and the engaging shaft 10 with respect to the main cylinder 6 in a first circumferential direction, while restricting it in a second circumferential direction opposite to the first circumferential direction. do. The ratchet portion 15 can be composed of, for example, an internal gear portion 15a provided on the inner peripheral surface of the body tube 6 and one or more elastic pieces 15b provided on the inner tube portion 12 as shown.

An upper end portion of the inner cylindrical portion 12 constitutes a restricting portion 13 . That is, the restricting portion 13 is provided integrally with the operated portion 11 . The restricting portion 13 is sandwiched between the outer peripheral surface of the split nut portion 7 and the inner peripheral surface of the main tube 6 to restrict radial expansion of the split nut portion 7 due to elastic deformation.

The extension member 3 can be easily assembled into the case tube 2 by simply pressing the male threaded tube 8 straight downward without rotating it from above into the split nut portion 7 which can be easily elastically deformed in the radial direction. . By pressing the operating member 4 against the case tube 2 from below, the operating member 4 is assembled to the case tube 2 via the rotary connecting portion 14. As a result, the restricting portion 13 prevents the radial elastic deformation of the split nut portion 7. It can be placed in the above position where it can be regulated. Therefore, when the operated portion 11 is operated, the threaded state between the threaded portion 7b of the split nut portion 7 and the male threaded cylinder 8 can be maintained well.

The inner peripheral surface of the restricting portion 13 has a convex portion facing the outer peripheral surface of the split nut portion 7 , and the outer peripheral surface of the restricting portion 13 has a convex portion facing the inner peripheral surface of the main tube 6 . Therefore, it is possible to suppress the generation of excessive sliding resistance in the circumferential direction when the operated portion 11 is operated.

Note that the configuration of the restricting portion 13 is not limited to the configuration having these convex portions. In addition, the restricting portion 13 is not limited to the structure that restricts the expansion of the split nut portion 7 by being sandwiched between the outer peripheral surface of the split nut portion 7 and the inner peripheral surface of the main body cylinder 6. Any configuration that restricts the expansion of the split nut portion 7 by contact with the . Although the restricting portion 13 has a slit extending vertically at one or more locations in the circumferential direction to facilitate demolding during molding, the restricting portion 13 is not limited to having a slit.

In addition, in order to adjust the sliding resistance with the inner peripheral surface of the main body tube 6, the inner tube portion 12 is made of one or more elastic pieces that contact the inner peripheral surface of the main body tube 6 as shown in the figure. A configuration having a moving portion 12a may be employed.

When using the delivery container 1, the operated portion 11 is operated to rotate in the first circumferential direction with respect to the case tube 2, thereby engaging the male threaded cylinder through the engaging shaft 10 that rotates integrally with the operated portion 11. 8 can be rotated with respect to the threaded portion 7b of the case tube 2, and the male threaded tube 8 can be sent toward the feeding port 18 integrally with the inner plate 9 by the action of the screw. Then, the contents C pushed up by the inner plate 9 and delivered from the delivery port 18 can be used.

When the operated portion 11 is operated, the inner plate 9 slides on the inner peripheral surface of the main body tube 6 in the circumferential and axial directions. airtightness between the inner plate 9 and the main body cylinder 6 can be maintained satisfactorily. Further, since the reverse rotation of the operated portion 11 is restricted by the ratchet portion 15, it is possible to prevent the content C in the storage portion S from being cracked or air-entrained due to the lowering of the middle plate 9. According to this embodiment, airtightness is improved by both the inner plate 9 (adhesive cylinder 9a) that closes the lower opening of the storage portion S and the insert member 16 that closes the upper opening of the storage portion S. Good airtightness of the object C can be achieved, thereby protecting the content C. That is, the delivery container 1 of the present embodiment can be used particularly advantageously as the delivery container 1 for the type of content C that requires good airtightness.

In addition, although the cap 5 is formed by insert molding in the first embodiment, it is not limited to this, and may be formed by assembling separate parts as in the second embodiment shown in FIG. 5, for example.

In the second embodiment, the cap 5 is formed by assembling a lid member 20 made of a soft material to the upper end portion of a cylindrical member 19 made of a hard material. An upper inner peripheral surface of the cap 5 is formed by the lid member 20 . Good airtightness of the feeding port 18 can also be achieved with such a configuration.

In the first embodiment, the upper tube end of the main body tube 6 forms the delivery port 18, but this is not limiting. For example, as in the third embodiment shown in FIG. A plug 21 made of a soft material (or a hard material) may be attached to the end, and the semi-solid or liquid content C may be delivered (discharged) through a discharge port 21a of the plug 21 . In this case, use as, for example, a tube-lip cosmetic container can be realized.

In the third embodiment, the plug 21 has a peripheral wall 21b fitted to the inner peripheral surface of the upper tube end of the main tube 6, and a top wall 21c connected to the upper end of the peripheral wall 21b and having a discharge port 21a. Note that the top wall 21c is not limited to being inclined with respect to the horizontal plane as illustrated. The cap 5 also has a sealing protrusion 5c that hangs down from the top wall 5b and can close the discharge port 21a. According to the third embodiment, better airtightness of the accommodating portion S can be achieved.

The present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the scope of the invention.

Therefore, the delivery container 1 of the above-described embodiment includes the male threaded cylinder 8, the case tube 2 having the threaded portion 7b screwed to the male threaded tube 8, and the storage portion S for the contents C, the male threaded tube 8 and the storage portion S, an engagement shaft 10 axially slidably and co-rotatably engaged with the inner peripheral surface of the male threaded cylinder 8, and a case cylinder integrated with the engagement shaft 10. 2, as long as it is a delivery container 1 having an operated portion 11 held by the case cylinder 2 so as to be rotatable with respect to the case cylinder 2 .

For example, the configuration in which the upper end of the engaging shaft 10 is positioned above the upper end of the male threaded portion 8a is not limited. Moreover, the lower end of the male threaded portion 8a is not limited to being positioned below the lower end of the case tube 2 . The outer peripheral portion 11b of the operated portion 11 is not limited to the structure extending upward from the bottom wall 11a. The configuration is not limited to the configuration in which the split nut portion 7 is provided to form the threaded portion 7b. A configuration in which the ratchet portion 15 is not provided may be employed. The inner plate 9 and the male threaded cylinder 8 may be configured separately. The operated portion 11 and the engaging shaft 10 may be configured separately.

In addition, the feeding container 1 of the above-described embodiment is provided integrally with the split nut portion 7 having the threaded portion 7b and the operated portion 11 in the above configuration, and the split nut portion 7 comes into contact with the outer peripheral surface to split.
