JP, 2014-188260, A

  In the delivery container described in Patent Document 1 described above, it is not easy to use up the contents inside the main body when the remaining amount of the contents decreases.

  The present invention has been made in consideration of such circumstances, and it is an object of the present invention to provide a feeding container in which the contents can be easily used up.

  In order to solve the above problems, the delivery container according to the first aspect of the present invention comprises a container main body having an upper cylinder and a lower cylinder rotatably provided about the container axis with respect to the upper cylinder; A holding unit for holding the content, and housed in the container body, and restricted in rotation around the container axis with respect to the upper cylinder, the holding unit radially extending the lower end portion of the content And a second holding member having a lower plate for supporting the lower end surface of the content from below, the second holding member comprising: a first holding member having a holding cylindrical portion surrounded from the outside; A guide shaft which is positioned below the plate and extends in the vertical direction is formed, and the first holding member includes a rise restricting portion which restricts the rise of the first holding member with respect to the container body by a predetermined amount or more; (2) a locking portion to be fitted to a locking projection formed on the holding member; In the lower cylinder, when the holding portion rotates with the upper cylinder around the container axis with respect to the lower cylinder, the lower cylinder engages with the guide shaft and is directed upward to the second holding member An engaging portion for applying a force is formed, and the strength of the rising restriction of the second holding member with respect to the first holding member by the locking projection and the locking portion is represented by F1, and When it is assumed that the strength of the rising restriction of the holding member with respect to the container body is F2, F1 <F2.

According to the first aspect, the contents can be reliably held by the holding cylindrical portion of the first holding member and the lower tray of the second holding member. In addition, when the upper cylinder and the lower cylinder are relatively rotated around the container axis, the holding portion rotates with the upper cylinder, and the engaging portion engages with the guide shaft, whereby the force directed upward to the second holding member Works. At this time, since the locking projection of the second holding member is fitted to the locking portion of the first holding member, the first holding member and the second holding member integrally rise.
When the first holding member rises by a predetermined amount with respect to the container main body, the rising restricting portion restricts the further rising of the first holding member. If the rotation operation is further continued in this state, the strength F1 of the rising restriction of the second holding member to the first holding member is smaller than the strength F2 of the rising restriction of the first holding member to the container main body. The lifting control by the locking projection is released. Therefore, when the second holding member having the lower plate ascends with respect to the first holding member having the holding cylindrical portion, the contents are pushed upward from the holding cylindrical portion, and the contents are easily used up. Is possible.

  Here, the second holding member may be formed with a connection portion connecting the lower plate and the guide shaft, and the locking projection may protrude radially outward from the connection portion.

  In this case, the upward force acting on the guide shaft can be smoothly transmitted to the locking projection.

  In addition, the locking projection may be formed in a curved surface shape that is convex outward in the radial direction.

  In this case, the force required for the locking projection to ride over the locking portion is reduced. Therefore, the configuration in which F1 <F2 can be easily realized.

  According to the above aspect of the present invention, it is possible to provide a feeding container which can easily use up the contents.

It is a longitudinal cross-sectional view of the delivery container which concerns on this embodiment. It is a longitudinal cross-sectional view of the delivery container in the state which removed the cap and raised the holding | maintenance part. (A) is an AA cross section arrow line view of FIG. (B) is a BB section arrow line view of FIG. It is a longitudinal cross-sectional view which shows the state which raised the 2nd holding member with respect to the 1st holding member from the state of FIG. It is a side view near the lower tray of the second holding member.

  Hereinafter, the delivery container of the present embodiment will be described based on the drawings. In the drawings used in the following description, in order to make the features easy to understand, the features that are the features may be enlarged for the sake of convenience, and the dimensional ratio of each component may be limited to the same as the actual Absent. Further, the present invention is not limited to the following embodiments.

  As shown in FIG. 1, the delivery container 1 has a bottomed cylindrical container body 2, a holding portion 4 accommodated inside the container body 2, and a cap 5 for closing the opening of the container body 2. Prepare. The holding unit 4 holds the contents. As the contents, for example, a rod-like body in which a cosmetic (lipstick, lip balm, stick eye shadow, etc.), a drug, a glue, or the like is formed in a rod shape is used.

(Direction definition)
Here, in the present embodiment, the central axis of the container body 2 is referred to as a container axis O. The direction along the container axis O is referred to as the vertical direction, the bottom side of the container body 2 along the vertical direction is referred to as the lower side, and the opening side is referred to as the upper side.
Further, in a plan view seen from the up and down direction, a direction intersecting the container axis O is referred to as a radial direction, and a direction circling around the container axis O is referred to as a circumferential direction.

(Container body)
The container body 2 includes a bottomed cylindrical lower cylinder 3 and an upper cylinder 50 disposed above the lower cylinder 3. The lower cylinder 3 and the upper cylinder 50 are relatively rotatable around the container axis O.
The lower cylinder 3 includes a bottomed cylindrical lower main body cylinder 10 and an inner cylindrical portion 20 fixed to the inside of the lower main body cylinder 10. In the present embodiment, the lower main body cylinder 10 and the inner cylindrical portion 20 are separately formed, but they may be integrally formed.

  The outer diameter of the lower main body cylinder 10 is substantially equal to the outer diameter of the cap 5 formed in a top cylindrical shape. As shown in FIG. 2, at the lower end portion of the peripheral wall 11 of the lower main body cylinder 10, a retaining stopper 11 a that protrudes radially inward is formed. A small diameter portion 12 having an outer diameter smaller than that of the peripheral wall 11 is formed at an upper end portion of the peripheral wall 11. The small diameter portion 12 is surrounded by the cap 5 when the cap 5 is attached to the container body 2. At this time, the lower end surface of the cap 5 abuts on or approaches the upper end surface of the peripheral wall 11.

A groove 13 is formed on the inner peripheral surface of the small diameter portion 12 so as to be recessed outward in the radial direction. The groove portion 13 is formed over the entire circumference of the inner peripheral surface of the small diameter portion 12.
The inner cylinder portion 20 has a guide cylinder portion 21 coaxially arranged with the container axis O, and an annular fixing portion 22 extending radially outward from the lower end portion of the guide cylinder portion 21. The fixing portion 22 is undercut and fitted to the retainer 11 a of the lower main body cylinder 10. The fixing portion 22 is press-fit and fitted in the peripheral wall 11 of the lower main body cylinder 10. Thereby, the inner cylinder portion 20 is fixed to the lower main body cylinder 10. In addition, the rotation of both the members 10 and 20 is performed by providing the control part which controls the relative rotation around the container axis O of both the members 10 and 20 in both or one of the inner cylindrical portion 20 and the lower main body cylinder 10. It may be regulated. At the upper end portion of the guide cylinder portion 21, an engagement portion 23 which engages with a guide shaft 43 described later is formed. The guide cylinder portion 21 has a role of guiding the vertical movement of the guide shaft 43.

  The upper cylinder 50 includes an upper main body cylinder 51 having an outer diameter equal to that of the small diameter portion 12 and a sliding cylinder 52 extending downward from the upper main body cylinder 51. The outer diameter of the sliding cylinder 52 is smaller than the outer diameter of the upper main body cylinder 51 and the outer diameter of the small diameter portion 12. The inner diameter of the sliding cylinder 52 is smaller than the inner diameter of the upper main body cylinder 51. As shown in FIGS. 2 and 3B, the inner circumferential surface of the sliding cylinder 52 is formed with a first longitudinal groove 52a which is recessed outward in the radial direction and extends in the vertical direction. The first longitudinal groove 52 a is formed over the entire length of the sliding cylinder 52 in the vertical direction. A plurality of (four in the present embodiment) first circumferential grooves 52 a are formed on the inner circumferential surface of the sliding cylinder 52 at equal intervals in the circumferential direction.

  A sliding projection 53 protruding radially outward is formed at the central portion in the vertical direction of the sliding cylinder 52, and a lower projection 54 projecting radially outward is formed at the lower end of the sliding cylinder 52. Is formed. The sliding projection 53 is located in the groove 13 of the lower cylinder 3. The sliding protrusion 53 and the lower protrusion 54 are disposed apart from each other in the vertical direction. The sliding protrusion 53 and the lower protrusion 54 extend in the circumferential direction all around the outer peripheral surface of the sliding cylinder 52. When the upper cylinder 50 rotates with respect to the lower cylinder 3 by the sliding projection 53 and the lower projection 54 sliding with respect to the lower cylinder 3, the inclination with respect to the lower cylinder 3 of the upper cylinder 50 is suppressed small. It can be rotated smoothly.

(Holding part)
The holding unit 4 includes a first holding member 30 and a second holding member 40.
The first holding member 30 includes a holding cylindrical portion 31 surrounding and supporting the lower end portion of the content from the outer side in the radial direction, and an annular locking portion 32 extending radially inward from the lower end portion of the holding cylindrical portion 31 And a lower cylindrical portion 33 extending downward from the locking portion 32.
The outer diameter of the holding cylinder portion 31 is smaller than the inner diameter of the upper main body cylinder 51 and larger than the inner diameter of the sliding cylinder 52. As shown in FIGS. 2 and 3A, the inner circumferential surface of the holding cylindrical portion 31 is formed with a second vertical rib 31a that protrudes radially inward and extends in the vertical direction. Two second longitudinal ribs 31a are formed at equal intervals in the circumferential direction. The number of second longitudinal ribs 31a may be one or three or more.

  As shown in FIG. 2, the outer diameter of the lower cylindrical portion 33 is smaller than the inner diameter of the sliding cylinder 52. As shown in FIG. 3B, at the lower end portion of the lower cylindrical portion 33, a plurality of slits S extending in the vertical direction are formed at equal intervals in the circumferential direction. Each slit S penetrates the lower cylindrical portion 33 in the radial direction. Thereby, a plurality of restriction pieces 34 are provided at the lower end portion of the lower cylindrical portion 33. A plurality of restriction pieces 34 are formed at equal intervals in the circumferential direction. On the outer peripheral surface of the lower cylindrical portion 33, a first longitudinal rib 35 which protrudes radially outward and extends in the vertical direction is formed. The first longitudinal rib 35 is formed over the entire length of the lower cylindrical portion 33 and the restriction piece 34 in the vertical direction. A plurality of first longitudinal ribs 35 are arranged at equal intervals in the circumferential direction. The number of first longitudinal ribs 35 is the same as the number of restricting pieces 34. The width in the circumferential direction of each first longitudinal rib 35 is smaller than the width in the circumferential direction of each restriction piece 34. Each first longitudinal rib 35 is located at a central portion in the circumferential direction of the outer peripheral surface of each restricting piece 34. In the circumferential direction, the width of each first longitudinal rib 35 and the width of each restriction piece 34 may be equal to each other.

  At the lower end portion of each restricting piece 34, a rising restricting portion 34a that protrudes outward in the radial direction is formed. That is, a plurality of the elevation restricting portions 34a are formed at equal intervals in the circumferential direction. Note that the number of the elevation restricting portions 34a may be changed as appropriate. The lower surface of the elevation restricting portion 34a is an inclined surface which is gradually inward in the radial direction as it goes downward. The upper surface of the elevation restricting portion 34 a extends in the direction orthogonal to the container axis O, and vertically opposes the lower end surface of the sliding cylinder 52. As described above, the elevation restricting portion 34a is formed in a substantially triangular shape in the longitudinal sectional view or the side view. The radially outer end of the elevation restricting portion 34 a is located radially outward of the inner peripheral surface of the sliding cylinder 52.

  When assembling the holding portion 4 to the container main body 2, the lower end portion of the first holding member 30 is inserted from the upper end opening portion of the upper main body cylinder 51. At this time, the inclined surface of the rising restricting portion 34a abuts on the upper end opening of the sliding cylinder 52, and the restricting piece 34 elastically deforms so as to fall inward in the radial direction. Thereafter, as the elevation restricting portion 34 a passes through the sliding cylinder 52 downward, the restriction piece 34 is restored and deformed radially outward. Thus, the restricting piece 34 is elastically deformable in the radial direction.

  The second holding member 40 has a lower plate 41 supporting the lower end surface of the content from below and a connecting portion 42 extending downward from the lower plate 41 and a guide shaft 43 extending downward from the connecting portion 42 A non-guided portion 44 extending downward from the guide shaft, and a retainer 45 formed at the lower end of the non-guided portion 44.

  The lower plate 41 is formed in a substantially disc shape. As shown in FIGS. 2 and 3A, the outer circumferential surface of the lower plate 41 is formed with a second longitudinal groove 41a which is recessed inward in the radial direction and extends in the vertical direction. The second longitudinal grooves 41a are formed in the same number as the second longitudinal ribs 31a at equal intervals in the circumferential direction. The relative rotation of the first holding member 30 and the second holding member 40 about the container axis O is restricted by positioning the second vertical rib 31 a in the second vertical groove 41 a.

  The connection portion 42 connects the lower plate 41 and the guide shaft 43. The connection portion 42 is formed in a cylindrical shape having an outer diameter smaller than that of the lower plate 41. The outer diameter of the connection portion 42 is smaller than the inner diameter of the locking portion 32. The connection portion 42 is disposed at the same position as the locking portion 32 in the vertical direction. The connection portion 42 is inserted radially inward of the locking portion 32 from above. At the lower end portion of the connection portion 42, a locking projection 42a that protrudes outward in the radial direction is formed. As shown in FIG. 5, the locking projection 42 a is formed in a curved surface shape that is convex outward in the radial direction. A plurality of (two in the present embodiment) locking projections 42a are formed at equal intervals in the circumferential direction. The locking projection 42 a is fitted to the locking portion 32. In the present embodiment, the locking projection 42 a is undercut fitted to the locking portion 32. The relative vertical movement of the first holding member 30 and the second holding member 40 is restricted by the locking portion 32 being vertically sandwiched by the locking projection 42 a and the lower plate 41. When a force of a predetermined magnitude is applied to move the second holding member 40 upward with respect to the first holding member 30, the locking projection 42a gets over the locking portion 32.

  The guide shaft 43 is located below the lower plate 41 and extends in the vertical direction. As shown in FIG. 5, a male screw portion is formed on the surface of the guide shaft 43. Further, the engaging portion 23 of the lower cylinder 3 is a female screw portion screwed with the male screw portion of the guide shaft 43 (see FIG. 2). When the guide shaft 43 rotates around the container axis O with respect to the lower cylinder 3, the guide shaft 43 and the engagement portion 23 are screwed together, whereby a force directed upward or downward acts on the guide shaft 43. In addition, as long as the guide shaft 43 moves up and down with relative rotation of the guide shaft 43 and the engagement portion 23, the shapes of the guide shaft 43 and the engagement portion 23 may be changed as appropriate. For example, a spiral groove extending in the vertical direction may be formed in the cylindrical guide shaft 43, and a protrusion located inside the spiral groove may be used as the engaging portion 23.

  As shown in FIG. 2, the non-guiding portion 44 is formed in a cylindrical shape. The surface of the non-guide portion 44 is not formed with a shape for moving the second holding member 40 such as an externally threaded portion up and down. Therefore, even if the non-guide portion 44 and the engaging portion 23 rotate in a state where the positions in the vertical direction coincide with each other, no force in the vertical direction acts on the second holding member 40. The stopper 45 is formed in a cylindrical shape having an outer diameter larger than that of the non-guide portion 44. The outer diameter of the stopper 45 is larger than the inner diameter of the engagement portion 23.

(Action)
Next, the operation of the delivery container 1 configured as described above will be described. In the following description, an operation to relatively rotate the upper cylinder 50 and the lower cylinder 3 around the container axis O is simply referred to as "rotation operation". When rotating, for example, the lower cylinder 3 may be rotated about the container axis O with respect to the upper cylinder 50 while holding the upper cylinder 50.

When using the delivery container 1 in the state shown in FIG. 1, the cap 5 is first removed from the container body 2.
Next, a rotation operation is performed. At this time, since the inner cylindrical portion 20 is fixed to the lower main body cylinder 10, the inner cylindrical portion 20 and the lower main body cylinder 10 do not rotate relative to each other. On the other hand, relative rotation between the upper cylinder 50 and the first holding member 30 is restricted by the first longitudinal rib 35 and the first longitudinal groove 52a. The relative rotation between the first holding member 30 and the second holding member 40 is restricted by the second longitudinal rib 31a and the second longitudinal groove 41a. Therefore, the first holding member 30 and the second holding member 40 rotate relative to the inner cylinder portion 20 of the lower cylinder 3 around the container axis O together with the upper cylinder 50.

  When the second holding member 40 rotates around the container axis O with respect to the inner cylindrical portion 20, the engaging portion 23 and the guide shaft 43 are engaged (screwed), and the second holding member 40 is directed upward. Power acts. At this time, since the locking projection 42 a is undercut fitted to the locking portion 32, the rise of the second holding member 40 with respect to the first holding member 30 is restricted. Accordingly, the first holding member 30 and the second holding member 40 integrally rise. The amount by which the first holding member 30 and the second holding member 40 are raised can be adjusted by the amount of rotation of the upper cylinder 50 with respect to the lower cylinder 3. Thus, the user can use the contents by raising the first holding member 30 and the second holding member 40 by a desired amount.

When the first holding member 30 ascends by a predetermined amount, the upper surface of the elevation restricting portion 34a abuts on the lower surface of the sliding cylinder 52, as shown in FIG. As a result, the rise of the first holding member 30 relative to the container main body 2 is restricted (see FIG. 2).
Here, in the present embodiment, the strength of the rise restriction of the second holding member 40 with respect to the first holding member 30 by the locking projection 42 a and the locking portion 32 is set to F1. Further, the strength of the rising restriction of the first holding member 30 with respect to the container main body 2 by the rising restriction portion 34a and the sliding cylinder 52 is set to F2.

More specifically, when the force F is applied to separate the first holding member 30 and the second holding member 40 from each other in the vertical direction, the locking projection 42 a passes over the locking portion 32 upward. It is the size of the force required at the time. That is, the strength F1 is a force necessary to release the restriction on the elevation of the second holding member 40 to the first holding member 30.
The strength F2 is a force by which the undercut fitting of the elevation restricting portion 34a to the slide cylinder 52 is released when a force is applied to separate the first holding member 30 and the upper cylinder 50 in the vertical direction from each other. The size of That is, the strength F2 is a force necessary to release the restriction on the container body 2 of the first holding member 30 from being lifted.

  At this time, in the present embodiment, F1 <F2. Therefore, when the rotation operation is further performed from the state shown in FIG. 2, the undercut with respect to the locking portion 32 of the locking projection 42a is performed before the undercut fitting of the elevation restricting portion 34a with respect to the sliding cylinder 52 is released. The engagement is released. Then, when the locking projection 42 a passes over the locking portion 32, a click feeling is generated. After that, the second holding member 40 ascends with respect to the first holding member 30 along with the rotation operation, so that the contents located inside the holding cylindrical portion 31 can be pushed upward by the lower tray 41.

When the rotation operation is further performed, as shown in FIG. 4, the upper surface of the lower plate 41 ascends to a position substantially equal to or above the upper end opening of the holding cylindrical portion 31 in the vertical direction. Thereby, the user can easily use up the content located inside the holding cylinder part 31.
At this time, since the non-guide portion 44 of the second holding member 40 and the engaging portion 23 are positioned at the same position in the vertical direction, the raising force does not act on the second holding member 40 even if the rotation operation is performed. It becomes idle. Further, since the stopper 45 is formed at the lower end of the non-guide portion 44, the second holding member 40 is prevented from being accidentally dropped from the first holding member 30.

  As described above, according to the delivery container 1 of the present embodiment, the lower end portion of the content is reliably held by the holding cylindrical portion 31 of the first holding member 30 and the lower tray 41 of the second holding member 40. Can. Then, when the remaining amount of the content decreases, the content on the inner side of the holding cylindrical portion 31 can be pushed upward by the lower plate 41, and the content can be easily used up.

In addition, since the locking projections 42a are formed in a curved shape that is convex outward in the radial direction, the force required when the locking projections 42a cross over the locking portion 32 is reduced. As a result, the configuration in which F1 <F2 can be easily realized.
Further, the locking projection 42 a is formed in the connecting portion 42 connecting the lower plate 41 and the guide shaft 43. For this reason, the upward force acting on the guide shaft 43 is smoothly transmitted to the locking projection 42a, and the undercut fit of the locking projection 42a with the locking portion 32 can be released more reliably.

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

  For example, in the embodiment described above, F1 <F2 is set by forming the locking projections 42a in a curved shape, but other methods may be used. For example, F1 <F2 may be satisfied by making the number of the locking projections 42a smaller than the number of the elevation restricting portions 34a. Alternatively, F1 <F2 may be satisfied by making the amount of engagement of the engagement projection 42a in the radial direction with respect to the engagement portion 32 smaller than the amount of engagement of the elevation restricting portion 34a with respect to the sliding cylinder 52 in the radial direction. Further, it is possible to set F1 <F2 by forming a tapered surface which gradually expands in diameter toward the lower side at the lower end opening edge of the locking portion 32 formed annularly.

In particular, the larger the difference between the strength F1 and the strength F2, the more reliably the above-described effects can be obtained. Therefore, the difference between the strength F1 and the strength F2 may be increased by appropriately combining the above-described modifications.
Moreover, in the said embodiment, although the latching protrusion 42a was formed in the connection part 42, the latching protrusion 42a may protrude radially outward from the lower plate 41, for example. In this case, the guide shaft 43 may extend downward from the lower plate 41, and the second holding member 40 may not have the connection portion 42.

  In addition, it is possible to replace components in the above-described embodiment with known components as appropriate without departing from the spirit of the present invention, and the above-described embodiments and modifications may be combined as appropriate.
