Description

[Detailed Description of the Invention] <<Industrial Application Field>> The present invention relates to a cap fitting structure for a container that allows the cap to be easily fitted to and removed from the neck of a container having a spout.

《Prior art》 Conventionally, this type of fitting structure was developed in 1973.
82256 is publicly known. In this known device, the outer surface of the neck of the container having the spout is formed into a substantially polygonal planar shape, and the polygonal shape includes a first side wall having a substantially vertical surface shape and a first locking protrusion at an intermediate portion in the vertical direction. and second side walls having portions are arranged alternately. The distance between the first side wall and the center of the neck is relatively short, while the distance between the second side wall and the center of the neck is relatively long.

Further, on the inner wall surface of the cap to be attached to the neck, a pair of second locking protrusions that can be locked with the first locking protrusions are disposed facing each other, and the first and second locking protrusions are oppositely arranged. The second locking protrusions are both inclined at substantially the same angle.

Further, the distance between the opposing second locking protrusions is approximately equal to the distance between the first side walls (shorter distance from the center) formed opposite to the neck.

To fit the cap onto the neck of the container, place the cap so that the opposing second locking projections of the cap are located above the first side wall of the neck, and Push it down to cover the neck, and then rotate the cap by a predetermined angle to engage the upper surface of the second locking protrusion of the cap with the lower surface of the first locking protrusion formed on the neck to prevent the cap from slipping out upwards. It fits in.

<<Problems to be solved by the invention>> However, in this conventional cap fitting structure, when the cap is placed over the neck of the container from above, the opposing second locking protrusions formed on the inner surface of the cap are When located above the first side wall (which is far from the center) of the neck, the distance between the opposing second side walls is longer than the distance between the protrusions, so the upper part of the second side wall I can't cover it by touching it. In other words, in order to close the cap, the second locking protrusion provided on the cap must be positioned above the first side wall of the neck before the cap can be placed over the neck. This positioning is relatively troublesome, especially when the cap is placed on the container while looking aside, as it is difficult to properly align the cap.

Furthermore, in order to fit the cap onto the container, it is necessary to place the cap on the neck and then rotate it through a certain angle, making it impossible to fit the cap with one hand, which is particularly difficult for cream or liquid cosmetic containers. When using the cap, it was extremely inconvenient because it was impossible to insert the cap while applying cream or the like to one hand.

The present invention was developed in view of the above-mentioned problems, and its purpose is to allow the cap to be placed over the neck of the container from any position, and by selecting the position to place the cap, it is possible to simply put the cap on. To provide a cap fitting structure for a container which is extremely easy to use and can be fitted by a one-touch operation of pushing downward from the container, or by rotating a predetermined angle after covering the container. be.

<Means for Solving the Problems> In order to achieve the above object, according to the cap fitting structure of the container according to the present invention, the locking protrusion of the neck portion having the spout, which protrudes upward in a cylindrical shape, is provided. In the container cap fitting structure for fitting the cap to the container by locking the locking protrusion of the cap at the neck portion, the neck portion may be divided into a substantially polygonal shape in plan view. Vertical first side walls and second side walls adjacent to the vertical side walls via the corners, which are arranged alternately in the circumferential direction of the neck, and which project from each second side wall and extend up and down along the side walls A first locking protrusion is formed diagonally in the direction and defines a fitting portion below the first locking protrusion, and a first locking protrusion is formed to be recessed in each of the second side walls and inclined in the vertical direction, and the lower end of the first locking protrusion is formed to be inclined in the vertical direction. an inclined guide groove continuously connected to the first locking protrusion; a flexible cap that is elastically deformable with respect to the planar outline of the neck and the first locking protrusion; From the inner wall surface toward the neck, the first
and at least a pair of protrusions are provided so as to be able to be fitted onto any upper end edge of the second side wall, facing each other across at least the plane outline dimension of the neck portion, and on the first locking protrusion. The inclined guide groove is formed obliquely along the first locking protrusion so as to be removably engaged with the neck from the circumferential direction, and is pressed downward against the second side wall. While being guided by the first side wall, the first locking protrusion is moved over and fitted into the first locking protrusion, while being lowered along the first side wall and attached to the neck. It is rotated in the circumferential direction, passes over the corner from the first side wall, enters the second side wall, and is removably fitted into the fitting portion below the first locking protrusion.
A second locking protrusion.

<<Operation>> First, when the second locking protrusion provided on the inner wall surface of the cap is located above the first side wall of the neck, when the cap is placed over the neck from this state, the opposing second locking protrusion The locking projections of the cap are spaced apart by at least the planar contour dimensions of the neck so that the second locking projection of the cap is lowered along the vertical first side wall to its lower portion. , covering the neck.

When the cap is rotated in the circumferential direction of the neck from this state, the second locking protrusion of the cap is moved from the first to The second side wall passes over the corner and enters below the first locking protrusion, and at this time, the second locking protrusion engages and disengages from the fitting portion below the first locking protrusion. The cap can be fitted freely, and the cap will be firmly attached to the neck.

Also, the second locking protrusion of the cap is connected to the second locking protrusion of the neck.
If the cap is located above the side wall of the neck, immediately push the cap downward against the neck. Then, the second
The locking protrusion moves downward within the inclined guide groove formed in the second side wall while being guided by this. At this time, since the second locking protrusion is guided by the inclined guide groove, unnecessary lateral movement thereof is regulated.
The second locking protrusion will surely move downward. Then, as the second locking protrusion approaches the first locking protrusion, the second The locking protrusion climbs over the first locking protrusion and "snaps".
While making a sound, the cap elastically returns to fit into the first locking protrusion, and the cap is securely fitted onto the neck.

That is, the cap can be placed over the neck of the container from any position.

<<Embodiments>> Preferred embodiments of the present invention will be described below with reference to the accompanying drawings.

The illustrated container 1 has a body 2 formed in the shape of a vertically elongated rectangular parallelepiped, and a cylindrical neck 4 having a spout 3 is integrally formed on the upper surface of the body 2, projecting upward. . This neck portion 4 has a cylindrical portion 5 at the upper end.
and a polygonal section 6 below.

The polygonal portion 6 of the neck portion 4 is formed with an approximately octagonal outline in plan view. And the polygonal part 6
There are two types of side walls that partition the
side walls 15 are arranged alternately along the circumferential direction of the neck portion 4. The first side wall 9 is formed in a substantially vertical plane shape, while the second side wall 1
5, each has a first plate projecting outward from the wall surface at an intermediate portion in the vertical direction, and inclined vertically at a predetermined angle along the side wall 15.
A locking protrusion 11 is disposed across this second side wall 15. Further, below the first locking protrusion 11, a fitting wall portion 12 as a fitting portion is formed which is partitioned by the first locking protrusion 11 and descends one step inward. and the lower part of the first side wall 9 are in communication via the corner.

Further, in the upper part of the second side wall 15, the side wall 15 is recessed and inclined in the vertical direction, and the lower end thereof is continuously connected to the first locking protrusion 11.
An inclined guide groove 10 is formed. in particular,
The inclined guide groove 10 is formed in the shape of an inclined surface such that the upper surface of the first locking protrusion 11 formed on the second side wall 15 gradually moves inward as it goes upward. Moreover, it is formed to extend in the vertical direction toward the upper part of the second side wall 15, that is, the upper part of the second side wall 15. The width of the inclined guide groove 10 is set to be slightly larger than the width of the second locking protrusion 14.

On the other hand, the cap 13 attached to the neck part 4 is formed as a rectangular cap having substantially the same shape in plan as the body part 2 of the container 1, and has a shape with respect to the plan outline of the neck part 4 and the first locking protrusion 11. It is configured to have flexibility and can be elastically deformed.

A second locking protrusion 14 is integrally formed in the center of each inner wall surface of the cap 13 facing the neck 4 so as to protrude inward. In particular, these second locking protrusions 14 are connected to the first side wall 9 and the second
The first side wall 15 is provided such that it can be fitted into any of the upper end edges 7, 8 of the side wall 15 of the neck portion 4, and is provided so as to protrude from the side wall 15 so as to be opposed to each other, with at least the plane outline dimension of the neck portion 4 apart.
It is formed obliquely along the first locking protrusion 11 so as to be releasably engaged with the locking protrusion 11 in the circumferential direction of the neck portion 4, and the second side wall 15 is formed diagonally with respect to the second side wall 15. It is pushed downward and is moved within the inclined guide groove 10 while being guided by it, and then passes over the first locking protrusion 11 and enters below it to be fitted into the first locking protrusion 11. At the same time, the corner portion is lowered along the first side wall 9 and rotated in the circumferential direction of the neck portion 4 to move the corner portion from the first side wall 9 to the second side wall 15. Step over the first locking protrusion 11
It is configured to enter below the fitting wall portion 12 and to be removably fitted into the fitting wall portion 12. Specifically, the opposing second locking protrusions 1 provided on the cap 13
The distance between the tips of 4-14 is the distance between the upper edges 7-7 of the opposing first side walls 9-9 provided on the neck 4, and the distance between the upper edges 8 of the second side walls 15-15. While forming the distance approximately equal to the distance between -8,
A pair of first locking protrusions 11-1 on the second side wall 15
The spacing is slightly narrower than the spacing of 1. As a result, the second locking protrusion 1 provided on the cap 13
4 is the first side wall 9 or the second side wall 1 of the neck portion 3;
Coupled with the flexibility of the cap 13, the second locking protrusion 14 of the cap 13 can be moved downwardly along each side wall 9, 15, regardless of where it is located above the side walls 9, 15. .

Next, the method of fitting the cap 13 of the above-described embodiment will be explained. There are two methods for fitting the cap 13 described above to the neck 4 of the container 1. That is, one method is to displace each side surface of the cap 13 by 45 degrees with respect to the side surface of the body 2 of the container 1, as shown in FIG. The portion 14-14 is positioned above the first side wall 9-9 of the neck portion 4, and from this state the cap 13 is placed over the neck portion 4. Then, the interval between the opposing second locking protrusions 14-14 is
Each upper end edge 7-7 of the opposing first side wall 9-9
, and since the first side wall 9 is a substantially vertical surface, the second locking protrusion 14 of the cap 13 extends along the first side wall 9, as shown in FIG. Smoothly descend to the lower part of the neck 4.
cover. From this state, as shown in FIGS. 4 and 5, when the cap 13 is rotated 45 degrees in the direction of the arrow along the circumferential direction of the neck 4, the flexibility of the cap 13 and the The second locking protrusion 14 crosses over the corner from the lower side surface of the first side wall 9 to the second side wall 15 and connects the first locking protrusion 11.
At this time, the upper surface of the second locking protrusion 14 is removably fitted into the fitting wall 12 below the first locking protrusion 11 of the second side wall 15. , the side surface of the cap 13 occupies the same vertical plane as the side surface of the body of the container 1, so that the cap 13 is tightly fitted onto the neck 4.

Another fitting method is as shown in Figure 1.
Align each side of the cap 13 with the side of the body 2 of the container 1 and position it above, lower the cap 13 as it is, align the second locking protrusion 14 with the inclined guide groove 10 of the neck 4, and then lower the cap. 13 to neck 4
All you have to do is push it downwards. Then,
The second locking protrusion 14 moves downward within the inclined guide groove 10 while being guided thereby. At this time, since the second locking protrusion 14 is guided by the inclined guide groove 10, unnecessary lateral movement thereof is regulated, and the second locking protrusion 14 is reliably moved downward. become. Then, when the second locking protrusion 14 contacts the first locking protrusion 11 from above, the cap 13
Push down even more firmly. Then, since the cap 13 has some elasticity, the second locking protrusion 14-14 expands the cap 13 slightly outward while expanding the first locking protrusion 1 as shown in FIG.
1 and enters below it, makes a "snapping" sound and elastically returns, and as shown in FIG.
is firmly fitted into the neck portion 4.

Of course, at this time, the side surface of the cap 13 occupies a position on the same vertical plane as the side surface of the body 2 of the container 1.

Further, in order to remove the cap 13 fitted by the above two fitting methods from the neck 4 of the container 1, the cap 13 is rotated in the direction opposite to the arrow in FIG. 4. As a result, the second locking protrusion 14 on the inner wall surface of the cap 13 extends from the fitting wall 12 of the second side wall 15 to the lower part of the first side wall 9. Therefore, when the cap 13 is pulled upward from this state, the cap 13 is separated from the container 1.

FIG. 9 shows another embodiment of the present invention, in which the first locking protrusion 1 of the second side wall 15
In place of the fitting wall part 12 in the first embodiment, an inclined groove part 12a is formed below the fitting wall part 12 as a similar fitting part, and the upper end of this inclined groove part 12a is connected to the first side wall 9.
It communicates with the middle part of. Therefore, in this embodiment, after the cap 13 is placed on the first side wall 9 so that the second locking protrusion 14 is located on the first side wall 9, when the cap 13 is rotated as shown in FIG. 13 second locking protrusions 14 are connected to the inclined groove portion 12a.
As the cap 13 is guided and pushed downward, the cap 13 descends to cover the neck 4 and close the spout 3. Conversely, when the cap 13 is rotated from the state shown in FIG. 5 to the state shown in FIG.
Since the second locking protrusion 14 of the cap 13 is positioned on the first side wall 9, the cap 13 can be easily removed by pulling the cap 13 upward from here. He will be forced to leave.

In addition, even in the case of this embodiment, the cap 1
If the second locking protrusion 14 of No. 3 is positioned above the second side wall 15 and the cap 13 is pressed downward, the second locking protrusion 14 will move through the states shown in FIGS. 6 and 7. The portion 14 comes to fit into the first engagement protrusion 11 and the inclined groove portion 12a.

<<Effects>> As described above, according to the cap fitting structure of the container according to the present invention, when the cap is placed over the neck of the container, the second locking protrusion of the cap is connected to the first locking protrusion of the neck.
When the cap is positioned above the side wall of the neck and can be placed over the neck, the second locking protrusion is placed below the first locking protrusion by rotating the cap in the circumferential direction of the neck. The cap can be removably fitted into the fitting part, and on the other hand, when the second locking protrusion of the cap is located above the second side wall of the neck part, the cap can be pushed downward against the neck part. The second locking protrusion can be fitted into the first locking protrusion, and the cap can be fitted onto the neck of the container from any position using either method. Therefore, there is no need for accurate positioning when fitting the cap, and the fitting operation becomes extremely simple.

In addition, in response to an upward pull-out force in the fitted state, the first locking protrusion locks the second locking protrusion, thereby ensuring sufficient fitting holding force.

In particular, when using a push-in operation, the cap can be fitted into the container with a single touch by pushing the cap downward, which is extremely convenient especially when the cap has to be fitted with one hand. . Moreover, since the second locking protrusion is guided by the inclined guide groove during this one-touch operation, unnecessary lateral movement thereof is restricted, and reliable and smooth downward movement can be ensured.
