Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention provides a container in which a locking portion provided on a cylindrical portion of the cap is locked to a horizontally long locking portion provided on the neck of the container body. The configuration for releasing the lock is 2.
Regarding the containers provided in the tiers.

(Prior Art) A structure having the above locking structure and releasing the lock without rotating the cylindrical portion of the cap around the neck is disclosed in Japanese Patent Application Laid-Open No. 59-93660 and Japanese Utility Model Publication No. 51-9534. It is disclosed in the publication No.

The cap disclosed in Japanese Patent Application Laid-open No. 59-93660 has an inner cylinder part and an outer cylinder part with a rectangular cross section, and the lower end portions of two opposing sides of the inner cylinder part are bent outward. , and has a protruding portion on the inner surface of the bent portion that engages with the locking portion of the neck of the container body, while the inner surface of the outer cylindrical portion located on the outside of each of the two opposing surfaces has the bent portion. It has a configuration in which a protrusion is provided that abuts on the bent portion so as to change the position of the bent portion vertically and lock the protruding portion with the locking portion of the neck portion. In this container, when only the outer cylindrical part is raised and the protrusion on the outer cylindrical part is above the bent part, the bent part bends outward, and the container body and the cap are not locked together. Once released, the cap can be removed from the container body.

In addition, in the case of Utility Model Publication No. 51-9534, by rotating the outer cylindrical part of the cap, the part that was holding down the bent part of the inner cylindrical part moves in the circumferential direction, and the bent part is moved in the circumferential direction. This structure allows the cap to be released from the neck of the container body.

Further, the inner cylinder part is formed into a cylindrical shape and made of a deformable material, and the inner surfaces of opposing parts of the inner cylinder part are locked with locking protrusions provided on the neck of the container body, respectively. The container body and the cap are locked by providing a locking protrusion to deform the circular shape of the inner cylinder part into an oval shape by pressing the part between the two locking protrusions from the outside in the circumferential direction of the inner cylinder part. There is a structure to solve.

(Problem to be solved by the invention) In the above two examples in which the lock is released by moving the outer cylinder part, a well-known structure is added to strengthen the fit between the container body and the outer cylinder part of the cap. It is possible to prevent unexpected unlocking by preventing movement of the cylindrical portion, but in the case where the lock is released by pushing the inner cylindrical portion from the outside, there is no known structure to prevent the inner cylindrical portion from deforming due to unexpected external force. I haven't been able to do it.

The present invention is a container in which the lock is released by pushing the inner cylindrical part from the outside, and has a structure that does not release the lock even if unexpected external force is applied, that is, a mechanism that releases the lock in two stages. The purpose is to obtain a container having the following properties.

(Means for Solving the Problem) In order to achieve the above-mentioned purpose, the container of the present invention has the head 3 of the container main body 1 as a cut-off plane portion in which opposing portions of a truncated cone are cut away in the vertical direction leaving the upper portions 9, 9. 1
2, 12, and the circular arc portions 10, 10 remaining between the cut plane portions 12, 12; The cap 17 includes a ceiling part 21, an outer cylindrical part 19 and an inner cylindrical part 20 hanging from the ceiling part 21,
The inner cylinder part 20 has horizontally elongated protrusions 26, 26 on its inner surface that engage with the stepped parts 11, 11, and the outer cylinder part 19
has a cross-sectional shape that matches the body 2 of the container body 1, and there is a connecting vertical rib 22 between the inner cylindrical portion 20 and the outer cylindrical portion 19 at a location between the horizontally long protrusions 26, 26.
22 is provided, and by pushing the outer cylindrical portion 19 from the side where the connecting vertical ribs 22, 22 are located, the inner cylindrical portion 20 is deformed into an elliptical shape, and the stepped portions 11, 1 of the container body are deformed into an elliptical shape.
1, the horizontally elongated protrusions 26, 26 of the cap are unlocked, and the cap 17 is removed. a rotatable member 38, which has elongated holes 27, 27 at symmetrical positions with 20 in between, is rotatable around the center line of the inner cylinder part 20, and is engaged with the cap 17 in the vertical direction; It is integral with the rotatable member 38 and the elongated hole portions 27, 27
When an external force is applied to the connecting vertical ribs 22, 22, it comes into pressure contact with the outer surface of the locking portion 25 having the horizontally long protrusion 26, thereby preventing the horizontally long protrusion 26 and the stepped portion 11 from being unlocked. Hanging support members 36, 36
A lock body 18 is attached to the cap 17, and extends from the point where the hanging support members 36, 36 press against the locking portions 25, 25 to the sides in the circumferential direction of the locking portions 25, 25. A mechanism is provided in which the elongated holes 27, 27 are rotatably formed.

(Function) Since the container of the present invention has the above structure, the inner cylinder part 20
When an external force is applied to deform the lock body into an elliptical shape, the locking portion 25 comes into pressure contact with the hanging support member of the lock body 18, and the locking between the stepped portion 11 and the horizontally long protrusion 26 is not released. Therefore, the lock between the container body and the cap is not released.

The locking is released only when the lock body 18 is rotated to move the hanging support member 36 to the side of the locking portion 25 and then the external force is applied.

(Example) This example is illustrated in FIGS. 1 to 5. The container body 1 has one end 6 of a body 2 having a trapezoidal cross-sectional shape.
It is a tube container in which the shoulder part 5 of the head part 3 is glued to the top.

The head 3 has a cut plane part 1 in which opposing parts of a truncated cone are cut in the vertical direction leaving the upper parts 9, 9.
2, 12, and the circular arc portions 10, 10 remaining between the cut plane portions 12, 12; The neck portion 4 has a constricted portion 13, and vertical grooves 14, 14 are provided in the upper portions 9, 9 of the neck portion 4, respectively. Note that 2 is the body of the container body 1.

Next, it has a cap 17 attached to the neck 4 of the container body 1, and a lock body 18 attached to the cap 17 to prevent the cap 17 from being accidentally removed from the container body 1.

The cap 17 includes an outer cylindrical portion 19 whose cross section is trapezoidal, which is close to the cross-sectional shape of the body portion 2 of the container body;
A ceiling part 21 extending substantially horizontally from the upper end toward the center, a cylindrical inner cylinder part 20 hanging down from the inner surface of the ceiling part 21, and an outer surface that protrudes upward from the center of the ceiling part 21 to prevent detachment. an upper cylindrical portion 29 having a ring 28;

The inner cylinder part 20 (FIG. 2) has the inner cylinder part 2 on its inner surface.
0 on the neck portion 4, the vertical groove 14,
14, and horizontally long protrusions 26, 26 that engage with the stepped portions 11, 11.
, and has slit portions 24 that open at the lower end of the inner cylinder portion 20 on both circumferential sides of each of the laterally elongated protrusions 26, 26.

Connecting vertical ribs 22, 22 between the inner cylindrical portion 20 and the outer cylindrical portion where the vertically elongated protrusions 32, 32 are provided.
The ceiling portion 21 of the cap 17 has the horizontally elongated protruding portion 26 located outside the upper cylindrical portion 29 and between the inner cylindrical portion 20 and the outer cylindrical portion 19 in an arc concentric with the inner cylindrical portion 20. . In this embodiment, the central angle of the arc of the elongated holes 27, 27 is 85°.

In addition, in FIG. 2, 25 is a horizontally long protrusion 26.
is a portion between the slit portions 24, 24, that is, a locking portion, and 33 is a positioning mark with respect to the lock body 18 provided on the cap 17.

The lock body 18 (FIG. 3) is a rotatable member 3 that is attached to the upper cylindrical portion 29 and has a locking ring 39 on the inner surface that locks the detachment prevention ring 28.
8, and hanging support members 36, 36, which are formed integrally with the rotatable member 38, have a chevron-shaped horizontal cross section, and are inserted into the holes 27, 27. The hanging support members 36, 36 are provided facing each other, and by rotating the rotatable member 38, the long hole portions 27,
27 can be moved to the center of the locking portion 25 of the inner cylinder portion 20 and to the circumferentially side portions of the locking portion 25.

Note that 37 is a reinforcing rib of the hanging support member 36;
3 is a cutout portion provided so that the locking portion 25 can bulge outward when the hanging support member 36 is located on the side of the locking portion 25 in the circumferential direction;
41 and 42 are marks indicating the rotational position of the lock body with respect to the cap, and mark 42 is similar to mark 41.
It was engraved at 225° clockwise.

To assemble the lock body 18 to the cap 17, insert a hanging support member 3 having a width of approximately 30 degrees into the elongated hole 27 formed in the ceiling 21 of the cap 17.
6 and cover the upper cylindrical portion 29 with the rotatable member 38 of the lock body 18. A retaining ring 39 is engaged with the detachment prevention ring 28 of the upper cylindrical portion 29, and the lock body 18 is rotatably attached to the cap 17. Since the locking ring 39 of the lock body 18 is locked below the detachment prevention ring 28 of the cap 17, the two will not be separated. Then, when the lock mark 42 of the lock body 18 is aligned with the alignment mark 33 of the cap 17, the reinforcing rib 37 of the hanging support member 36 is located approximately at the center of the arcuate outer surface of the locking portion 25 having the horizontally long protrusion 26. Mark 42 was engraved as follows.

Next, turn the lock body 18 in the above position counterclockwise.
When the opening mark 41 of the lock body 18 is aligned with the positioning mark 33 of the cap 17 by rotating 55 degrees, the reinforcing rib 37 of the hanging support member 36 is located outside the slit part 24 of the inner cylinder part 20, and the locking part 25 can expand outward and release the lock.

A state in which the cap 17 with the lock body 18 attached to the container body 1 is attached and the hanging support member 36 is positioned at the locking portion 25 is shown in FIGS. 4a and 5. To release the lock, align the open mark 41 on the lock body 18 with the alignment mark 33 on the cap 17.
A two-step operation is performed: moving the hanging support member 36 to the side of the locking portion 25 (see FIG. 4b), and then pressing the opposite lower end of the outer cylindrical portion 19 of the cap. is necessary. In other words, when the hanging support member 36 is in a position to support the locking portion 25, the lock cannot be released even if the outer cylinder portion 19 is pressed.

As shown in FIG. 6, the effect of preventing lock release is enhanced by providing a protrusion piece 51 at the lower end of the hanging support member 36 that contacts the vicinity of the horizontally elongated protrusion 26 of the locking portion 25. .

The structure of this embodiment is as described above, but the rotatable member 38 is attached to the lock body 1 with respect to the cap 17.
The hanging support member 36 may have any other configuration as long as it is rotatable around the center line of the inner cylinder portion 20 and has a configuration that locks the cap in the vertical direction and prevents it from coming off. The shape of the cap is not limited to that of the embodiment, and the horizontal cross section may be semicircular or the like, and the mechanism for preventing rotation of the cap relative to the container body may have other known configurations.

(Effects of the invention) According to the container of this invention, by positioning the hanging support member 36 at the horizontally elongated protrusion 26 of the inner cylinder part 20, the container can be used even if an unexpected external force is applied to the outer cylinder part. The lock between the main body and the cap will never come loose.
