Description

  The present invention relates to a drawing container for extracting powder contained by a drawing operation, and an inside plug for a drawing container provided inside the drawing container.

  As a container for containing powder (for example, salt, sugar, grated cheese, detergent, etc.) as the content, there is known a drawing container for extracting the content by a drawing operation of displacing the container in an inverted posture and moving it up and down. . In such a dispensing container, once opened, it may absorb moisture in the air and part of the contents may become a lump. When such a lump is formed, the opening for extracting the content may be blocked by the lump, and the unsolidified content may not be extracted. Also, if the opening is enlarged, the contents will not be clogged, but since the lumps will be shaken out, it is necessary to crush the lumps later.

  To solve such a problem, the applicant of the present application proposes a swing-out container in which a plurality of crosspieces are bridged inside the container body and a projection having a pointed tip is provided on the lower surface of the crosspiece as shown in Patent Document 1. . According to such a swing-out container, it is possible to crush it by hitting a lump on the crosspiece or projection, so it is necessary to crush it during the swing-out operation or shake it up and down with the lid closed to crush it beforehand. The contents can be extracted smoothly. Further, even if a large lump remains, it is caught on the crosspiece, so that only the small contents can be extracted.

  By the way, the lump can be sufficiently crushed even with the drawing container of Patent Document 1, but it may be difficult to break depending on the storage condition and the type of contents, and the drawing operation may have to be repeated.

  An object of the present invention is to improve such a point, and to provide an inner plug for a dispensing container capable of crushing lumped contents more efficiently than before, and a dispensing container using this inner plug. The purpose is to do.

The present invention is an inner stopper used for a drawing container for extracting powder from a container body by a drawing operation,
An annular holding portion held by the container body, and one end portion thereof is connected to the holding portion, and extends from there toward the bottom portion of the container body toward the central axis of the container body, and the other end portion. Is an inner plug for a dispensing container, which comprises a plurality of rod-shaped portions interconnected with each other.

  The rod-shaped portion preferably has at least one edge in a cross-sectional shape.

  It is preferable that the rod-shaped portion has a protrusion protruding from the rod-shaped portion.

  It is preferable that the protrusion has at least one edge at the tip of the protrusion.

  It is preferable that the rod-shaped portion linearly extends from the one end toward the other end.

  It is preferable that the rod-shaped portion extends in a spiral shape from the one end toward the other end in a direction in which the rod extends around the central axis.

  Further, the present invention includes a lid body having a ceiling wall provided with an opening for extracting powder, which is attached to an opening portion of the container body, and holds the holding portion between the ceiling wall and the opening portion. Then, it is a drawing container which holds the above-mentioned inner plug for the drawing container.

  The inner stopper for a swing-out container of the present invention has an annular holding portion held by the container body, and one end portion of which is connected to the holding portion, and from which the direction toward the central axis of the container body approaches the bottom of the container body. And a plurality of rod-shaped portions that are connected to each other at the other ends. That is, the inner plug has a cone-like shape with the other end as the apex as a whole, and has a larger size than the conventional protrusion, so that a large lump can be efficiently crushed.

  Further, the rod-shaped portion preferably has at least one edge in the cross-sectional shape, and in this case, the lump can be crushed also by the edge of the rod-shaped portion, so that the efficiency is further improved.

  When the rod-shaped portion is provided with a protrusion protruding from the rod-shaped portion, the lump can be crushed by the protrusion. By providing at least one edge at the tip of this protrusion, the lump can be crushed more efficiently.

  By the way, it is possible to sufficiently crush a lump even when the rod-shaped portion extends linearly from one end to the other end, but the rod-shaped portion is the center of the container body from one end to the other end. In the case of extending spirally around the axis, the extending distance of the rod-shaped portion becomes longer, so that the contact length with the lump becomes longer and the crushing can be performed more efficiently. In addition, since the lump becomes easy to move along the rod-shaped portion extending in a spiral shape, the lump becomes easy to move with the rotation around the central axis of the container body, so that the lump can be more efficiently crushed. .

  Further, in a drawing container provided with such an inner stopper, a lid body having an upper wall provided with an opening for extracting powder is provided and attached to the mouth portion of the container body. It is preferable to sandwich the holding portion between the two, so that the assembly can be easily performed with a small number of steps.

  Hereinafter, one embodiment of the drawing container according to the present invention will be described with reference to FIGS. 1 and 2. In addition, in this specification etc., "upper" and "lower" refer to the orientation in the state where the container body is in the upright posture, as shown in FIG.

  The drawing container of the present embodiment includes a container body 1, an inner stopper 2, a lid 3, and a cover 4.

  The container body 1 has a disc-shaped bottom portion 1a, a cylindrical body portion 1b connected to an edge portion of the bottom portion 1a, and an upper end portion of the body portion 1b, and has a smaller diameter than the body portion 1b. And a mouth portion 1c. A male screw portion 1d is provided on the outer peripheral surface of the mouth portion 1c. Further, inside the container body 1, an internal space N capable of accommodating powder contents is formed.

  In the container body 1 of the present embodiment, the bottom portion 1a and the body portion 1b are integrally connected, but these are separated and configured by two members, and both are fixedly held by an undercut or a screw. Good. Further, the container body 1 is not limited to the cylindrical shape, and may be a rectangular tube shape.

  The inner plug 2 is provided with a plate-shaped holding portion 2a having a circular ring shape in a plan view. The holding portion 2a of the present embodiment has a circular ring shape corresponding to the cylindrical container body 1. However, when using a rectangular tube-shaped container body, for example, the holding portion 2a also has a rectangular ring shape. As shown in FIG. 1, the holding portion 2a is placed on the upper end portion of the mouth portion 1c. A circular through hole 2b is provided in the center of the holding portion 2a.

  On the lower surface of the holding portion 2a, one end portion 2c1 is integrally connected to the holding portion 2a, extends from there toward the bottom portion 1a in a direction approaching the central axis O of the container body 1, and the other end portions 2c2 are mutually connected. A plurality of rod-shaped portions 2c to be connected are provided. The rod-shaped parts 2c of this embodiment are eight in total, and are provided at equal intervals with respect to the holding part 2a. The rod-shaped portion 2c of the present embodiment spirally extends from the one end portion 2c1 toward the other end portion 2c2 in a direction that circulates the central axis O. The rod-shaped portion 2c has a polygonal cross section (quadrangle in this embodiment) and has four edges. The one end portion 2c1 is in airtight contact with the inner peripheral surface of the mouth portion 1c.

  As shown in FIG. 2, the inner plug 2 of this embodiment has a cone shape (conical shape in this embodiment) with the other end 2c2 as the apex as a whole. In addition, for example, when the container body is formed into a rectangular tube shape, it is preferable that the inner plug as a whole has a pyramidal shape in accordance with the container body. Further, the cross-sectional shape of the rod-shaped portion 2c is not limited to the quadrangular shape, and may be a polygonal shape such as a circular shape or a triangular shape, but the effect of crushing the contents is more effective. To obtain, it is preferred to have at least one edge in cross-sectional shape.

  The lid 3 includes a plate-shaped top wall 3a extending along the upper surface of the holding portion 2a. A circular opening 3b is provided at the center of the top wall 3a. A peripheral wall 3c is provided at the outer edge of the top wall 3a so as to expand downward. The peripheral wall 3c is configured to be fitted and held on the outer periphery of the mouth portion 1c. As a result, the inner plug 2 is held by the container body 1 with the holding portion 2a being sandwiched between the top wall 3a and the upper end portion of the mouth portion 1c. In addition, when holding the lid body 3 in the mouth portion 1c, a method using screws or undercutting may be used. Further, in the present embodiment, the inner plug 2 is held by the lid body 3, but any form may be adopted as long as the inner plug 2 does not come off from the mouth portion 1c of the container body 1 during use. Good.

  The cover 4 includes a plate-shaped top wall 4a that covers the top wall 3a, and a cylindrical outer peripheral wall 4b that is connected to the outer edge of the top wall 4a and surrounds the mouth 1c. Further, a female screw portion 4c adapted to the male screw portion 1d is provided on the inner peripheral surface of the outer peripheral wall 4b. To attach the cover 4 to the container body 1, an undercut may be adopted instead of the screw. Alternatively, a hinge may be provided at the end of the outer peripheral wall 4b, and the hinge and the top wall 4a may be integrally connected to each other so that the top wall 4a can swing.

  When using the drawing container having such a form, the cover 4 is removed and the container body 1 is displaced to the inverted posture to perform the drawing operation. As a result, the powder in the internal space N passes through the gap between the adjacent rod-shaped portions 2c, passes through the through hole 2b and the opening 3b, and is extracted to the outside. Although the opening 3b has a relatively large size, since the gap between the adjacent rod-shaped portions 2c is relatively small, the powder in the internal space N is not extracted at one time.

  Here, since the inner plug 2 has a conical shape with the other end portion 2c2 as an apex as a whole, even if a part of the powder in the internal space N becomes a lump, it can be efficiently crushed. . Further, since the rod-shaped portion 2c has an edge in the cross-sectional shape, the lump can be crushed even at this edge. Further, the lumps are likely to move along the rod-shaped portion 2c extending in a spiral shape, and as a result, the lumps move with rotation, so that the lumps can be crushed more efficiently.

  The drawing container according to the present invention is not limited to the above. For example, the lid body 3 of the present embodiment has a relatively large opening 3b in the central portion of the ceiling wall 3a, but the size and number thereof can be appropriately changed according to the contents. For example, it is assumed that a plurality of small holes (small hole group) are provided near the outer edge of the top wall 3a to extract a small amount of contents, and a plurality of holes larger than the small holes (on the outer edge near the opposite side). A group of holes may be provided to extract a large amount of contents. Further, in this case, in place of the cover 4 described above, one cover portion that covers the above-described small hole group and another lid portion that covers the above-described hole group are provided, and each cover portion is a central portion. A hinge cover that can be opened and closed by a hinge provided in the vicinity (may be close to the outer edge portion) may be provided. The number of hinge covers preferably corresponds to the number of hole groups, but at least one is sufficient. Further, when providing the hinge cover, the lid is omitted, while the hinge cover has a hole for extracting the contents and a top wall for covering the holding portion of the inner stopper to sandwich the holding portion, It is possible to adopt a configuration in which the top wall is covered to close the hole and a lid portion integrally connected to the top wall via a hinge is provided. In this case, it is preferable that the upper surface of the top wall and the upper surface of the lid are flush with each other when the lid is closed. For example, the structure as shown in FIG. Is preferably lower than the other portions) so that the top wall has a portion covered by the lid portion lower than the other portions. The hinge cover may be integrated with the lid body and the lid body may be omitted. In addition, in order to improve airtightness when not in use or in use, a sealing material (for example, a sheet-shaped member made of aluminum foil or synthetic resin, etc. ) May be attached or interposed, or a sheet-like member (packing or the like) may be interposed on the lower surface of the top wall 4a of the cover 4.

  Further, the inner plug according to the present invention is not limited to the one described above, and it is also possible to employ the inner plug shown in FIG. 3, for example. The inner plug 20 shown in FIG. 3 is provided with a holding portion 20a and a through hole 20b having the same configuration as the holding portion 2a and the through hole 2b described above. Further, the rod-shaped portion 20c, like the rod-shaped portion 2c described above, extends in a spiral shape from the one end portion 20c1 toward the other end portion 20c2 in a direction to circulate the central axis O. Are different in number (10 in this embodiment). With such an inner plug 20, the lump can be efficiently crushed similarly to the inner plug 2.

  The inner plug may be that shown in FIG. The inner plug 21 shown in FIG. 4 includes a holding portion 21a and a through hole 21b, which have the same configurations as the holding portion 2a and the through hole 2b. The rod-shaped portions 21c spirally extend from the one end portion 21c1 toward the other end portion 21c2 in a direction to circulate the central axis O, and eight rod-shaped portions 21c are provided in the same manner as the rod-shaped portions 2c described above. Further, the rod-shaped portion 21c is provided with a protrusion 21d protruding outward, and the lump can be crushed also by this protrusion 21d. Although the protrusions 21d of this embodiment are provided on both side surfaces of the rod-shaped portion 21c, they may be provided on either side surface. The protrusion 21d may have a circular shape or a polygonal shape such as a triangular shape, but if it has at least one edge, the lump can be crushed more efficiently. The protrusion 21d of the present embodiment has a hexagonal shape in a plan view, and can efficiently crush a lump with four edges excluding a portion connected to the rod-shaped portion 21c.

  Further, as the inner plug, the one shown in FIG. 5 can be adopted. The inner plug 22 shown in FIG. 5 includes a holding portion 22a and a through hole 22b, which have the same configurations as the holding portion 2a and the through hole 2b. The rod-shaped portion 22c extends linearly from the one end 22c1 toward the other end 22c2. The rod-shaped portion 22c has a triangular cross-sectional shape and has three edges. The rod-shaped portion 22c is provided with a protrusion 22d that projects outward. The projection 22d of the present embodiment has a quadrangular shape (trapezoidal shape) in a plan view, and the lump can be efficiently crushed by the two edges excluding the portion connected to the rod-shaped portion 22c.

  The inside plug according to the present invention can be modified in various other ways, and the thickness and number of the rod-shaped portions may be appropriately changed in order to make the gap between the rod-shaped portions suitable for the contents. Further, the shape of the protrusion can be changed appropriately. Further, in the above-described embodiment, the protrusions are projected in the circumferential direction toward the adjacent rod-shaped portions, but the protruding direction may be radially inward or outward, upper side or lower side, or a combination thereof. Good. Moreover, the combination of the rod-shaped portion and the protrusion can be appropriately changed.
