DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container with an overcap, and more particularly to a container with an overcap which prevents the overcap from being detached from a container body.

[0002]

2. Description of the Related Art In general, there is known a container with an overcap in which an overcap can be attached to and detached from a container body. This container with an overcap is widely used, for example, as a container for cosmetics.

FIG. 8 shows a spout container as an example of a conventional container with an overcap. As shown in FIG. 1, the spout container 1 has a configuration including an aerosol container main body 2, a valve 3, a spout 4, an overcap 5, and the like.

The aerosol container body 2 is filled with contents such as a hairdressing material and a discharge agent (eg, LPG). The valve 3 is a valve body that opens and closes when the stem 6 is pressed, and is configured to close when the stem 6 stands upright and to open when pressed.

[0005] The spout 4 is formed by resin molding.
The nozzle portion 7, the operation button 8, the shoulder cover portion 9 and the like are integrally formed. The spout 4 is configured so that the nozzle portion 7 and the operation button 8 can be displaced with respect to the shoulder cover portion 9. Also, the shoulder cover 9 is fixed to a mounting cup 10 disposed on the upper part of the aerosol container main body 2, so that the spout 4 can be attached to the aerosol container main body 2.
Fixed to Further, the nozzle portion 7 is connected to the stem 6.

Therefore, the stem 6 is opened by operating the nozzle portion 7 or the operation button 8, and the contents filled in the aerosol container body 2 are discharged from the stem 6.
Further, since the nozzle portion 7 is connected to the stem 6 as described above, the content discharged from the stem 6 is discharged from the nozzle tip portion to the outside through the hole 7a formed in the nozzle portion 7. You.

The overcap 5 is used when the spout 4 is not used (when the spout container is not used).
Is fitted and attached to the attachment portion 4a formed at the outer peripheral portion of the. The overcap 5 has a cylindrical shape with a bottom and covers the valve 3, the spout 4, and the like when attached to the spout 4, thereby protecting the valve 3, the spout 4, and the like. .

FIG. 9 shows a spout 4 and an overcap 5.
It is a figure which expands and shows the fitting position with. As shown in the figure, an overcap-side protrusion 11 protruding inward is formed near the open end of the overcap 5. Further, a spout-side protrusion 13 protruding outward is formed on the attachment portion 4a of the spout 4.

Therefore, the overcap 5 is used for the spout 4
When mounted on the mounting portion 4a, the overcap-side projection 11 and the spout-side projection 13 are undercut-fitted, whereby the overcap 5 is mounted on the spout 4. Conventionally, the fitting strength of the overcap 5 to the spout 4 is 5 to 30.
N was set.

[0010]

As described above, since the valve 3 is configured to discharge the contents when the stem 6 is pressed, some force is applied to the operation button even if the user does not intend. When it acts on 8, the contents are discharged. Further, as described above, the overcap 5 has the overcap-side projection 11 and the spout-side projection 13 attached to the spout 4 by undercut fitting, and the fitting strength thereof is relatively 5 to 30N. Since the overcap 5 is set to a low value, the overcap 5 easily comes off the spout 4 when an external force is applied.

Therefore, for example, even when the spout container 1 (a container with an overcap) is carried in a bag or the like with the overcap 5 attached, the overcap 5 comes off the spout 4 with a slight external force. In this state, the nozzle portion 7 and the operation button 8 are exposed, so that when the nozzle portion 7 or the operation button 8 is pressed by the external force, the contents are discharged. For this reason, in the conventional mounting structure of the overcap 5, there is a problem that the inside of the bag is stained, or the discharge agent may be exhausted before the entire contents are not used.

The present invention has been made in view of the above points, and has as its object to provide a container with an overcap that can prevent the overcap from coming off when not in use.

[0013]

Means for Solving the Problems In order to solve the above problems, the present invention is characterized by taking the following means.

According to a first aspect of the present invention, there is provided a container body having a mounting portion, an operation portion operated at the time of use for discharging contents, and a mounting portion formed at an open end of the overcap main body. In a container with an overcap, which is configured by an overcap attached to the container body so as to cover the operation unit by fitting to the mounted portion, an engaging projection protruding outward on the container body is provided. Along with the provision, the overcap is formed with an extending portion extending in the mounting direction to the container main body, and at least in a state where the overcap is mounted on the container main body, the extending portion forms the engaging projection. It is characterized in that it is configured to engage so as to sandwich it.

According to the invention, in a state where the overcap is mounted on the container body (hereinafter, this state is referred to as a mounted state), the overcap is formed by fitting the mounting portion to the mounting portion of the container body. In addition to being fixed to the main body, it is also fixed by the fact that the extension formed on the overcap is engaged so as to sandwich the engaging projection of the container main body.

As described above, since the overcap is fixed to the container main body at two places separated from each other, the overcap does not easily come off from the container main body even when an external force is applied, and the erroneous operation of the operation section is reliably performed. Can be prevented.

According to a second aspect of the present invention, in the container with an overcap according to the first aspect, an elongated hole is formed in the extending portion, and the engaging projection is movable relative to the elongated hole. When the overcap is removed from the container main body, the engagement between the mounting portion and the mounted portion is released by the engagement protrusion relatively moving in the elongated hole. The overcap is configured to be detached from the container body by rotating the extension portion about the engagement protrusion.

According to the present invention, since the engaging projection is relatively movably engaged with the elongated hole formed in the extending portion,
When the overcap is pulled out of the container body, the engagement protrusion relatively moves in the elongated hole, whereby the fitting between the mounting portion and the mounted portion is released.

Further, the overcap is configured so that the extension portion is detached from the container body by rotating the extension portion around the engagement projection. In this detached state, the extension portion and the engagement projection are engaged. Maintain the combined state.
Accordingly, even when the overcap is used to project the contents, the overcap is kept connected to the container body, so that the overcap can be prevented from being lost.

[0020]

Next, embodiments of the present invention will be described with reference to the drawings.

FIGS. 1 to 4 show a container 20A with an overcap according to a first embodiment of the present invention. In the present embodiment, an aerosol container will be described as an example of the container 20A with an overcap. FIG. 1 is a perspective view of a container 20A with an overcap,
FIG. 2 is a front view and a side view of the container 20A with an overcap, and FIGS.
FIG. 4 is a diagram for explaining a method of removing A from an aerosol container main body 30.

The container 20A with the overcap is roughly composed of the aerosol container body 30 and the overcap 40.
A. Aerosol container body 30
Is filled with contents such as a hairdressing material and a discharge agent such as LPG. A mounting cup is fixed to the upper opening portion of the aerosol container body 30 by winding, and a valve is provided at a central position of the mounting cup. This valve is provided with a stem, and is configured to perform an opening and closing operation when the stem is pressed. Since the mounting cup, the valve, and the stem have a known structure, they are not shown.

An operation button 31 is attached to the stem. The operation button 31 is formed by resin molding, and is pressed by the user when discharging the contents (hereinafter, this time is referred to as the time of use). The operation button 31 is provided with a discharge port 32 for discharging the contents. When the user presses the operation button 31, the stem is pressed, whereby the valve is opened,
The contents filled in the aerosol container main body 30 are urged by the discharge agent and discharged to the outside from the discharge port 32 through the stem.

On the upper part of the main body 30 of the aerosol container, a mounted portion 33 is provided. This mounted part 33
The above-described mounting cup may be used, and when a shoulder cover is provided from the viewpoint of improving the design of the container 20A with an overcap, the shoulder cover may be formed on the shoulder cover. Overcap 4 described later
The mounting portion 41 formed at 0A is configured to fit with the mounted portion 33.

Further, an engagement projection 34 is formed on the outer periphery of the aerosol container body 30. This engagement projection 34
Is a cylindrical projection, and the cylindrical aerosol container body 3
0 is provided so as to protrude outward from the surface.
In addition, a pair of the engagement protrusions 34 are provided on the outer periphery of the aerosol container main body 30 so as to be separated by 180 ° (FIG. 2B).
reference).

Incidentally, the engagement projection 34 is provided on the aerosol container body 3.
0 and the aerosol container body 30
May be retrofitted by welding or the like. When the shoulder cover is provided on the aerosol container main body 30, the shoulder cover may be provided with the engagement projection 34.

Since the operation button 31 is pressed by the user, the operation button 31 is provided so as to protrude upward from the upper surface of the aerosol container body 30 in order to improve operability (see FIG. 2). ). Therefore, the operation button 3
When the aerosol container main body 30A is carried in a state where 1 is exposed, an external force is easily applied to the operation button 31.

Further, as described above, the operation button 3
1 is configured to open and discharge the contents by being pressed (that is, the stem is pressed). Therefore, when any external force is applied to the operation button 31 and pressed when the portable device is carried, the contents are discharged. As described above, problems such as soiling the inside of the bag being carried and running out of the ejection agent before the contents are not completely used occur. For this reason, the aerosol container main body 30 is configured to have an overcap 40A that covers the operation button 31 attached thereto.

Next, the overcap 40A will be described. The overcap 40A is formed of, for example, a transparent resin, and the aerosol container body 30 described above is formed.
Is attached to the mounting portion 33 provided in the first position. Further, the overcap 40A is provided with a mounting portion 41 and an extension portion 4 on a cap body 46 having a bottomed cylindrical shape.
2A is formed.

The mounting portion 41 is formed at the inner peripheral end (opening end) of the overcap 40A, and is configured to be fitted to the mounted portion 33 provided on the aerosol container main body 30. The mounting portion 41 is formed such that an overcap-side protrusion (not shown) protrudes inside the cap body 46. In addition, a spout-side concave portion (not shown) that fits with the overcap-side protrusion is formed in the mounted portion 33.

Therefore, when the overcap 40A is attached to the aerosol container body 30, the overcap-side projection and the spout-side recess are fitted with undercut, and the overcap 40A is connected to the aerosol container body 3.
0 is attached. However, since the fitting strength by the undercut fitting is a relatively low value of about 5 to 30 N, the overcap 40 </ b> A can easily be formed only by the fitting force between the mounting portion 41 and the mounted portion 33 when an external force is applied. It comes off from the aerosol container main body 30. It is also possible to increase the fitting strength by the undercut fitting, but if the fitting strength is increased, the overcap 40
A becomes difficult to remove, and the usability decreases.

Therefore, the container 20A with an overcap according to the present embodiment has a configuration in which the extension portion 42A is formed in the overcap 40A. This extension 42A
Sets the overcap 40A in the aerosol container body 30.
Is formed so as to extend in the mounting direction (the direction indicated by arrow A2 in the figure). The extension 42A has a long hole 4
3, and a curved portion 44 is formed at the end of the long hole 43 in the direction of arrow A2 in the figure. This curved portion 44
Is set equal to or slightly larger than the diameter of the engagement protrusion 34.

The engagement projection 34 formed on the aerosol container main body 30 is configured to be located in the long hole 43. Therefore, the engagement protrusion 34 is configured to be engaged with the extension 42 </ b> A with both sides sandwiched. Furthermore,
The engagement protrusion 34 is configured to be relatively movable within the elongated hole 43.

With the above configuration, as shown in FIG. 2, the overcap 40A is
Mounted state (hereinafter, this state is referred to as mounted state)
In the overcap 40A, the mounting portion 41 is fitted to the mounted portion 33 so that the aerosol container body 30
And the extension 42A formed on the overcap 40A is fixed by engaging the engagement projection 34 of the aerosol container main body 30A.

As described above, since the overcap 40A is fixed to the aerosol container main body 30A at two separated positions in the mounted state, the overcap 40A can be prevented from detaching from the aerosol container main body 30 even when an external force is applied. . Specifically, assuming that an external force F1 is applied from the side in a state where the container 20A with the overcap shown in FIG. 2A is viewed from the front, the external force F1 is fitted between the mounting portion 41 and the mounted portion 33. It is received at the engagement position and also at the engagement position between the engagement protrusion 34 and the extension 42A. Further, when an external force F2 is applied from the side in a state where the container 20A with the overcap shown in FIG. 2B is viewed from the side, the external force F2 is at a fitting position between the mounting portion 41 and the mounted portion 33. As well as being received, it is also received at a position where the extension portion 42 </ b> A contacts the surface of the aerosol container body 30.

As described above, since the external forces F1 and F2 applied to the overcap 40A in the mounted state are dispersed at two places, even if the external force is applied, the overcap 4
OA is not easily detached from the aerosol container body 30. Therefore, according to the configuration of the present embodiment, the overcap 40A is firmly attached to the aerosol container body 30, and even if the aerosol container body 30 with the overcap 40A is carried, for example,
The overcap 40A does not easily come off the aerosol container body 30. Accordingly, it is possible to prevent the ejection of the contents due to the detachment of the overcap 40A when carrying, etc., and it is possible to reliably prevent the inside of the bag or the discharge agent from being exhausted before the contents are completely used.

Next, the operation of removing the overcap 40A from the aerosol container body 30 in the container 20A with the overcap having the above-described configuration will be described. Replace the overcap 40A with the aerosol container body 3
In order to remove the overcap 40A from the aerosol container main body 30, as shown in FIG. Thereby, the engagement between the mounted portion 33 and the mounting portion 41 is released.

The only force required at this time is a force for releasing the fitting between the mounted portion 33 and the mounting portion 41.
No force required for pulling is generated at the engaging portion between the and the extending portion 42A. Therefore, the overcap 40 </ b> A can be easily pulled out from the aerosol container main body 30 with good operability.

As described above, the elongated portion 43A is formed with the elongated hole 43. By pulling out the overcap 40A from the aerosol container main body 30, the engaging projection 34 relatively moves in the elongated hole 43. Moving. Then, when the engagement protrusion 34 is engaged with the curved portion 44 of the extension portion 42A, the overcap 40A is rotated in the direction of arrow B in the figure as shown in FIG. Thereby, the overcap 40A is located at a position separated from the operation button 31.

The extension 42A is provided with an overcap 40A.
Even when the button is detached from the position covering the operation button 31, it remains engaged with the engagement protrusion.
Therefore, even when the contents are projected, the overcap 40A is kept connected to the aerosol container body 30, so that the overcap 40A can be prevented from being lost. It should be noted that the over cap 40A shown in FIG.
The operation of attaching 0A to the aerosol container main body 30A is the reverse of the above-described operation at the time of removal, and therefore the description thereof will be omitted.
