The container main body 14 has, on the inner peripheral surface of the opening portion, a female screw 32 complementary to the male screw 28 of the lid 16 </ b> A, and a projection 30 protruding inside the container main body 14 from the female screw 32 to the bottom 15 side.

The protrusion 30 is disposed on the opening side of the container body 14 with respect to the return portion 38 when the cap 12A is mounted on the container body 14. The projection 30 has a tapered shape in which the projection length gradually increases from the opening of the container body 14 toward the bottom 15. The protruding length is a length in a direction perpendicular to the inner peripheral surface of the container body 14.

As shown in FIG. 3, a plurality of projections 30 are provided at predetermined intervals in the circumferential direction of the container body 14, and four projections 30 are arranged in the present drawing. The size of the protrusion 30 can be appropriately selected. For example, when the inner diameter of the container body 14 is 54 mm, the circumferential length of the protrusion 30 is preferably about 2 mm to 5 mm. The container body 14 contains one or more substances (second substances, not shown in the figure) selected from the above-mentioned substances different from the first substances.

返 し As shown in FIG. 4, it is preferable that the turning portion 38 of the bottom cover 20 and the projection 30 of the container body 14 have complementary shapes. The outer diameter of the bottom lid 20 is smaller than the inner diameter of the container body 14 and larger than the inner diameter of a circle defined by an arc connecting the tips of the plurality of protrusions 30. That is, the outer edge of the return portion 38 and the tip of the projection 30 are formed so as to overlap when viewed from the axial direction of the container body 14. In this specification, when the cap 12A enters the container main body 14, the surfaces where the projection 30 and the return portion 38 come into contact with each other are the entry surfaces 43 and 45, and when the cap 12A retreats to the opening of the container main body 14, the protrusion 30 The surfaces where the return portions 38 contact each other are referred to as return surfaces 47 and 49.

It is preferred that it is below the degree. The angle (hereinafter referred to as the cap-side turning angle) _θc2 between the turning surface 49 of the turning portion 38 and the direction parallel to the central axis is preferably 90 degrees or more.

As described above, by defining the angles θ _b1 , θ _b2 , θ _b3 , θ _c1 , θ _c2 , and θ _c3 , the protrusion 30 can be fixed to the bottom lid 20 fixed to the cap 12A from the opening side toward the bottom 15 side. And the movement of the bottom lid 20 fixed to the cap 12A from the bottom portion 15 side toward the opening side is more reliably stopped.

(how to use)
A procedure for putting a substance into the container 10A with a cap will be described. As an example, a case where powder is used as the first substance and liquid is used as the second substance will be described. First, as shown in FIGS. 5A and 5B, the canopy 22 of the lid 16A is turned downward, and the first substance 40 is put into the storage portion 27 from the opening that has turned upward (FIG. 5A). Next, the bottom cover 20 is inserted into the opening until the tip of the outer wall portion 18 contacts the outer peripheral plate portion 41 (FIG. 5B). The bottom lid 20 closes the lid 16 </ b> A when the seal portion 23 contacts the inner peripheral surface of the opening area 26. Thus, the cap 12A in which the first substance 40 is stored in the storage section 27 is obtained.

と し By turning the canopy 22 upward and screwing the male screw 28 into the female screw 32, the cap 12A is attached to the container body 14 in which the second substance 42 has been previously placed (FIG. 6A). The lid 16A moves downward in the axial direction by the rotation in the closing direction. When the entry surface 45 contacts the entry surface 43 of the projection 30, the return portion 38 is radially outward with respect to the projection 30 (solid arrow in FIG. 6A) because the return portion 38 and the projection 30 have complementary tapered shapes. ), A force is generated radially inward of the return portion 38 (in the direction of the dashed arrow in FIG. 6A). The container body 14 is elastically deformed so as to expand in the radial direction by a radial outward force on the projection 30. The cap 12 </ b> A enters the container body 14 while elastically deforming the container body 14. When the return portion 38 passes through the projection 30, the radial force is removed, and the container body 14 is elastically deformed and returns to its original shape (FIG. 6B). The container main body 14 is hermetically closed by rotating the cap 12A in the closing direction until the opening end of the container main body 14 contacts the sealing surface 36. As described above, the container with cap 10A in which the first substance 40 and the second substance 42 are stored in a separated state is obtained.

Next, an operation when the first substance 40 stored in the cap 12A is transferred into the container body 14 will be described. The lid 16A is rotated in the opening direction. The cover 16A moves upward in the axial direction by rotation. When the lid 16 </ b> A moves upward, the turning surface 49 of the turning portion 38 comes into contact with the turning surface 47 of the protrusion 30. Since the cap-side turning angle θ _C2 and the container-side turning angle θ _b2 are each 90 degrees or more, the axially downward force is applied to the return portion 38 and the radially inner side is applied to the projection 30 (in FIG. ), A force is generated outward in the radial direction (in the direction of the solid arrow in FIG. 6C) on the return portion 38.

(4) The above force increases as the lid 16A moves upward and the axial force increases. Therefore, the upward movement of the lid 16A increases the force of blocking the upward movement of the bottom lid. The force causes the bottom lid 20 to fall off the tip of the outer wall portion 18 and fall into the container body 14 (FIG. 6C). The first substance 40 falls into the container body 14 together with the bottom lid 20. The first substance 40 that has dropped into the container body 14 mixes with the second substance 42 stored in the container body 14. The bottom lid 20 that has fallen into the container body 14 functions as a stirrer when the container 10A with a cap is shaken, and mixes the first substance 40 and the second substance 42 more efficiently.

The lid 16A once rotated in the opening direction is again rotated in the closing direction, and the opening end of the container body 14 comes into contact with the sealing surface 36, thereby sealing the container body 14. After the mixing is completed, the user can drink the food or drink in the container body 14 by opening the lid 16A.

(Action and effect)
The container 10A with a cap includes the lid 16A, the bottom lid 20, and the container body 14, thereby holding the first substance 40 and the second substance 42 in a separated state, and opening the cap 12A to open the first substance. 40 and the second substance 42 can be mixed. Since the outer wall 18 has the male screw 28 for fixing the cap 12A to the container body 14 and the housing 27 for housing the first substance, the structure can be simplified as compared with the conventional case. In addition, the container 10A with a cap can omit components that come into contact with the bottom lid 20, so that the number of components can be reduced as compared with the related art.

Since the container 10A with a cap can transfer the first substance 40 into the container body 14 without touching the bottom lid 20 and exposing the first substance 40 to the outside air, food and drink can be obtained in a more sanitary and simple procedure. be able to.

容器 The container 10A with a cap can mix the first substance 40 and the second substance 42 immediately before the user drinks, so that the versatility is higher. For example, conventionally, when an acidic beverage for the purpose of replenishing a high protein is produced, there is a problem that the protein precipitates and it is difficult to obtain a stable quality. On the other hand, the container 10A with a cap according to the present embodiment stores, for example, a protein concentrated powder as the first substance 40 in the cap 12A and an acidic raw material water as the second substance 42 in the container body 14 so that the user By mixing immediately before drinking, it is possible to provide the user with an acidic beverage before the protein is precipitated.
