[0004]
[Problems to be solved by the invention]
In the case of the former of the above conventional technique, since the contents cream is scrubbed directly with hands, germs and foreign substances enter the container, and the contents are not hygienic, and the contents adhere to the side edges and lid members of the container. It was easy to get dirty. In addition, since the contents adhere to the back surface of the lid member, it is not possible to provide a projection shape or the like for sealing and mounting the lid member. However, there is a problem that the number of parts increases.
[0005]
Further, in the latter case of the above conventional technique, the number of parts such as the inner lid is large and the cost is high. Furthermore, when the lid is pressed, the contents are not produced if the cap orifice is closed with a finger, so that the opening of the orifice must be pushed so as not to be blocked, resulting in poor operability. Furthermore, there is a problem that the contents remain in the holes of the inner lid and the cap, and the contents that cannot be used up eventually increase.
[0006]
The present invention has been made in view of the above-described conventional problems, and an object of the present invention is to provide a container in which contents can be easily and hygienically taken out with a simple structure.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1 to 3 show an embodiment of the present invention. A container 10 according to this embodiment includes a container main body 11 and a lid member 54 described later. The container main body 11 includes a cylindrical main body side surface 12. And a bottom portion 14 in which a lower surface opening of the main body side surface 12 is closed. The main body side surface 12 has a hollow thinning structure, and the inner peripheral surface of the main body side surface 12 is formed by a relatively thin cylindrical inner main body side surface 16. The inner peripheral surface has a uniform circular shape with the same inner diameter from the upper end portion 16a to the lower end portion 16b. On the outer side of the inner main body side face 16, a cylindrical outer main body side face 18 having a slightly larger diameter than the inner main body side face 16 is provided concentrically with a predetermined lightening space. The upper end portion 18 a of the outer main body side surface 18 is integrally and continuously formed from the upper end portion 16 a of the inner main body side surface 16 through the hook-shaped extension portion 20. Further, the lower end portion 18b of the outer main body side surface 18 extends downward from the inner main body side surface 16b.
[0011]
An inner bottom surface 22 is formed integrally with the bottom portion 14 on the inner side of the container 10 at a substantially right angle continuously from the lower end portion 16b of the inner body side surface 16. On the outer side of the inner bottom surface 22, an outer bottom surface 24 formed separately in a disk shape is provided to be engaged with the inner peripheral surface of the lower end portion 18 b of the outer body side surface 18. In the mounting method, an engagement groove portion 26 is formed on the inner peripheral surface of the outer main body side surface 18b, and when the outer bottom surface 24 is pushed into the outer main body side surface 18, the outer main body side surface 18 is once elastically deformed and spreads. When fitted, the elastic deformation is restored and the outer bottom surface 24 is locked. This attachment may be welded by heating or ultrasonic treatment. Further, a cylindrical support portion 28 that protrudes toward the outer bottom surface 24 is provided on the outer surface of the inner bottom surface 22, and the front end of the support portion 28 is substantially in contact with the outer bottom surface 24.
[0012]
The upper end portion 16 a of the inner body side surface 16 is provided with a cylindrical mounting portion 30 formed by extending the inner body side surface 16 upward with the same inner diameter, and a lid described later is provided on the outer peripheral surface of the mounting portion 30. A male screw 32 to which the member 54 is screwed is formed.
[0013]
An inner lid 34 is slidably fitted inside the attachment portion 30 of the container 10. The inner lid 34 is formed continuously with a circular top surface portion 36 that is fitted to the attachment portion 30 and the inner body side surface 16 continuous therewith in a slidable manner, and a peripheral portion of the top surface portion 36. A short cylindrical sliding contact portion 38 is provided along the inner peripheral surface of the mounting portion 30 at a right angle with respect to 36.
[0014]
In the center of the top surface portion 36, an extrusion hole 40 that is a pair of through holes that penetrate the top surface portion 36 is provided. The pair of extrusion holes 40 are positioned symmetrically in the radial direction across the center of the top surface portion 36. In the vicinity of the center of the top surface portion 36, a protrusion 42 that continuously surrounds the pair of extrusion holes 40 is formed to rise from the top surface portion 36. The protrusion 42 is formed in an oval shape with the extrusion hole 40 as the center, and the cross-sectional shape of the protrusion 42 in the radial direction is a concave curved surface that decreases toward the center of the oval. A content 44 such as a creamy medicine or cosmetic is placed under the inner lid 34 and inside the main body side surface 12.
[0015]
An inner plug 46 is provided in the extrusion hole 40 of the inner lid 34. The inner plug 46 is provided with an oval holding plate 48 that covers the protrusion 42, and an edge 50 that is perpendicular to the holding plate 48 is formed around the periphery of the holding plate 48. On the surface of the holding plate 48 opposite to the edge portion 50, a pair of rod-shaped plug portions 52 that are inserted in close contact with the extrusion holes 40 are formed.
[0016]
A lid member 54 is detachably screwed to the outer peripheral surface of the mounting portion 30 of the container 10. The lid member 54 is provided with a circular upper surface 56 and a cylindrical lid side surface 58 continuous to the peripheral edge of the upper surface 56, and is formed on the attachment portion 30 of the main body side surface 12 on the inner side of the lid side surface 58. A female screw 60 that is screwed into the male screw 32 is formed. In addition, a small protrusion 62 that contacts the upper end surface 30a of the mounting portion 30 is provided on the back surface of the upper surface 56 of the lid member 54. A large protrusion 64 is provided in contact therewith. The lid member 54 is attached with the inside of the container sealed by the small protrusion 62 and the large protrusion 64 coming into contact with the attachment portion 30.
[0017]
Next, the usage method of the container 10 of this embodiment is demonstrated. When taking out the contents 44, the lid member 54 is removed from the attachment portion 30 on the side surface 12 of the main body, and the inner plug 46 is removed from the extrusion hole 40 of the inner lid 34. Then, a part of the top surface portion 36 of the inner lid 34, for example, the inside of the long circle surrounded by the protrusion 42 is pressed with a finger. At this time, one of the extrusion holes 40 may be closed with a finger. Then, pressure is applied to the contents 44, the inner lid 34 is pushed down below the attachment portion 30 and the inner body side face 16, and the contents 44 are pushed out from the unsealed extrusion holes 40, and It collects inside the part 42. At this time, the inner lid 34 moves slightly downward by the amount of the extruded content 44. Then, by moving the finger, the contents 44 accumulated in the ellipse surrounded by the protrusions 42 are scooped and used in the designated usage. Then, the inner lid 34 reaches the inner bottom surface 22 in a state where the contents 44 are lost.
[0018]
According to the container 10 of this embodiment, it has a simple structure, and a necessary amount of the contents 44 can be taken out and used in a sanitary manner, and the contents in the container 10 are not randomly touched with fingers. Therefore, it is possible to prevent bacteria and foreign substances from entering the container 10. In addition, since the contact area between the air and the content 44 is reduced, the content 44 is effectively prevented from being oxidized and dried. The main body side surface 12 has a thinned structure, and sink marks generated during molding can be prevented by eliminating the thick portion. As a result, the inner cross-sectional shape of the inner body 16 has a uniform circular inner peripheral surface from the upper end portion 16a to the lower end portion 16b, and the inner lid 34 slides smoothly and the contents 44 do not leak. The outer main body side surface 18 of the main body side surface 12 can be formed to have the same diameter or large diameter as the lid member 54 and has a good appearance and a high-class feeling. Since the bottom portion 14 is not sinked and the inner bottom surface 22 is formed flat, the top surface portion 36 of the inner plug 34 abuts the entire surface of the inner bottom surface 22 when the content 44 is eliminated, and the content 44 is not wasted. Can be used up. In addition, it is possible to reduce the resin material used by reducing the thickness and shorten the molding cycle time during molding.
[0019]
Further, since the extrusion hole 40 is surrounded by the protrusion 42, the portion where the content 44 coming out of the extrusion hole 40 adheres is restricted to the inside of the protrusion 42. Can be used cleanly. The protrusion 42 is curved to form a dent, and when the contents 44 are scooped with a finger, the curved surface of the dent and the fingertip are in close contact with each other. Can do. Since the dent of the protrusion 42 approaches the outer periphery of the protrusion 42, the contents 44 do not sag outside the protrusion 42 when scooped up with a finger. And since the two extrusion holes 40 are provided, when pushing down the inner lid 34, all the extrusion holes 40 are not obstruct | occluded and the contents 44 can be extruded reliably. Since the protrusion 42 is formed in an oval shape on the top surface portion 36 and the extrusion holes 40 are arranged in the longitudinal direction, when the extrusion hole 40 is pushed with a finger, as shown in FIG. By closing the extrusion hole 40 located at a position far from the user, the inner lid 34 is pushed down, and then the content 44 is moved from the previous extrusion hole 40 by moving the finger toward the extrusion hole 40 from which the content has been extruded. Is extruded. In this state, the contents 44 can be scooped only by moving the finger forward, and the contents can be scooped cleanly without hanging or leaving the contents.
[0020]
Further, since the contents 44 do not adhere to the lid member 54, projections 62 and 64 for sealing and attaching the lid member 54 to the mounting portion 30 of the side surface 12 of the main body can be formed. There is no need to affix, and the number of parts can be reduced and the number of assembly steps can be reduced. Moreover, since only a small amount of contents 44 remain inside the extrusion hole 40 in the inner lid 34, it can be used up without waste. The inner plug 46 seals the extrusion hole 40 of the inner lid 34, so that even if the content portion 44 has a low viscosity such as gel, the content 44 does not come out of the extrusion hole 40 before use or when carried. It can be stored safely.
[0021]
The container of the present invention is not limited to the above embodiment, and the extrusion hole may be an elongated long hole or the like other than those provided with two circular through holes. May be. The shape of the protrusion surrounding the extrusion hole, the shape of the inner plug, and the like can be changed as appropriate. The contents are not limited to pharmaceuticals and cosmetics, but can be used for various creams. In addition to creams, the contents can be used for all cream-like materials including ointments, pastes, gel bodies, and the like. In addition to the above-described embodiment, the hollow structure of the main body side face or bottom may be formed by assembling these two members, for example, the inner main body side face and the inner bottom face are integrated, and the outer main side face and the outer bottom face are integrated.
[0022]
【The invention's effect】
The container of the present invention has a simple structure, and the contents can be taken out and used hygienically by an easy operation. Moreover, since the extrusion hole which extrudes the content is surrounded by the protrusion along the shape of the finger, it can be easily scooped along the finger easily without spreading the content. Furthermore, by providing an inner plug so that the extrusion hole can be closed, the contents do not come out of the extrusion hole when carried around, even when used for cream or gel having low viscosity.
