Description

[Detailed description of the invention] The present invention locks the dial-type lid by a combination of a locking mechanism of the dial-type lid of the container, and more specifically, a dial display of the dial-type lid fitted externally to the mouth of the container body. This invention relates to a locking mechanism for a dial-type lid of a container for unlocking.

Conventionally, locking mechanisms for dial-type lids of containers of this type have been proposed, for example, in Japanese Utility Model Application No. 57-80423 and Japanese Utility Model Application No. 57-167165. In other words, all of these devices form a notched recess on the inner circumferential surface of the dial ring that constitutes the lid, and provide a plurality of protrusions projecting from the outer circumferential surface of the mouth of the container body that can fit into the notched recess. The container is constructed so that the lid can be opened only when the dial ring is rotated and the notched recess of the dial ring and the protrusion of the container body are brought into positional correspondence.

However, in such a conventional dial-type lid locking mechanism, multiple protrusions must be formed on the container body, which makes the container manufacturing extremely complicated and reduces the work efficiency of the manufacturing work. At the same time, it had fatal drawbacks such as increased production costs.

Moreover, since the container has a special shape in which a protrusion is formed on the outer peripheral surface of the opening, it is not possible to obtain the desired locking mechanism by combining the above-mentioned dial type lid with a general commercially available container. It became necessary to manufacture a special container as described above for the dial type lock mechanism, and the complexity of the manufacturing work could not be solved at all.

The present invention was devised in order to eliminate all of these drawbacks, and to provide a locking mechanism for the dial-type lid as described above without forming the protrusions as described above on the container body. A completely new and useful dial type container that can greatly facilitate the manufacture of containers, thereby improving the efficiency of the manufacturing work and reducing manufacturing costs, and which can also be applied to commercially available containers. The purpose is to provide a locking mechanism for the lid.

In order to achieve such an object, the present invention has a container body which has at least one groove formed on the outer circumferential surface of the opening of the container body, and has an engaging protrusion on the inside that can be engaged with the groove. The flexible piece is fitted into at least two outer rings formed by hanging the flexible piece from the side surface of a substantially cylindrical lid body with an open bottom and displaying a dial display section on the outer peripheral surface. The outer ring and the same number of inner rings having one or more cutout recesses on the inner peripheral surface are fitted together, and both of the fitted rings are attached to the lid main body so that the inner ring rotates at the same time when the outer ring rotates. The engagement protrusion of the flexible piece and the groove of the container body are engaged or engaged by fitting the outer ring and rotating the outer ring to separate or match the positions of the notch recess and the flexible piece. The configuration is such that the connection can be canceled.

In the locking mechanism of the dial type lid having such a configuration, first, in order to set the desired dial display that can be unlocked, the notch recess of the inner ring is aligned with the position of the desired dial display part of the outer ring. Then, fit the inner ring to the outer ring, and then fit the two or more pairs of rings fitted in this way so that the flexible piece of the lid body is located at the position of the notch recess of the inner ring. A dial type lid is assembled by fitting the lid body onto the outside, and then this dial type lid is externally fitted onto the mouth of the container body. At this time, the flexible piece of the lid main body is fitted into the notch recess of the inner ring by the engagement protrusion formed on the inner side hitting the outer peripheral surface of the container main body when the flexible piece is inserted into the opening. The dial-type lid is bent outward, and as a result, the dial-type lid is fitted into the mouth of the container body very smoothly.

When the outer ring is arbitrarily rotated in this state, the position of the cutout recess of the inner ring, which rotates at the same time as the outer ring, is moved away from the position of the flexible piece, and the inner peripheral surface of the inner ring causes the flexible piece to move away from the position of the flexible piece. outward deflection is completely prohibited. Therefore, even if an attempt is made to pull the dial type lid upward in this state, the flexible piece will not bend, and the engagement state between the engaging protrusion of the flexible piece and the concave groove will be reliably maintained. The lid will be locked.

On the other hand, to release this locked state, rotate each outer ring to match the preset dial display, and the notch recess of the inner ring will again match the position of the flexible piece of the lid body, resulting in the corresponding The flexible piece becomes in a state where it can be bent outward, and the engagement state between the engagement protrusion and the groove is released, and the lock is released.
Then, if you pull the dial cover upward in that state,
At the time of external fitting, the flexible piece of the lid main body similarly bends outward to be fitted into the notch recess of the inner ring, making it possible to remove the dial type lid very smoothly and easily.

In this way, the present invention locks the dial-type lid by rotating the outer ring to engage the engaging protrusion of the flexible piece of the lid body with the concave groove of the container body, or locks the dial-type lid, or connects the engaging protrusion and the concave groove. Since the mechanism is such that the locking state of the dial type lid can be released by releasing the engagement with the lid, there is no need to form multiple protrusions on the container body side as in the conventional case, and it is only necessary to form a recess. The desired locking mechanism for the dial-type lid can be obtained, making it much easier to manufacture the container than in the past, significantly improving workability and significantly reducing manufacturing costs. It has come to have a great effect.

Furthermore, since it can be applied to common commercially available containers that only have grooves formed therein, the above-mentioned dial-type lid can also be fitted externally to commercially available containers having such grooves. A dial-type lid locking mechanism is now available.
This has the particular advantage that it is also possible to omit the manufacture of the container completely.

Furthermore, since it can be applied to such commercially available containers, it has the practical benefit of being widely applicable to a wide variety of containers such as bottles for whiskey and cosmetics.

EMBODIMENT OF THE INVENTION Hereinafter, embodiments of the present invention will be described according to an example shown in the drawings.

FIG. 1 shows an exploded front view of a dial-type lid as an example, and FIGS. 2 to 4 are sectional views of the lid body constituting this dial-type lid, a plan view of the outer ring, and a plan view of the inner ring. Figures are shown respectively.

In Figures 1 to 4, 1 has a flange 2 on the top surface.
It is a roughly cylindrical synthetic resin lid body having an opening 3 on the lower surface, and a lid body 1 that can be turned inward or outward between two slits 4 formed in the vertical direction of the lid body 1. A flexible piece 5 that can be bent is vertically provided, and an engaging protrusion 6 that can be engaged with the groove 14 of the container body 15 is provided protruding from the inside of the lower part of the flexible piece 5. Reference numeral 17 indicates an annular recess projecting from the lower outer peripheral surface of the lid body 1. Reference numeral 7 denotes a projection for marking the dial display, which is formed on the side surface of the flange portion 2 of the lid body 1 and on the upper part of the flexible piece 5. Reference numerals 8a, 8b, and 8c are three outer rings with a planar decagonal shape that can be fitted onto the lid main body 1 and formed into a barrel shape when assembled, and the outer peripheral surface has numbers 1 to 10 for dial display. A display section 9 consisting of Greek numerals is displayed, and an annular protrusion 10 is provided on the inner peripheral surface to protrude inward.
11a, 11b, 11c are the outer rings 8a, 8
The outer ring 8a,
8b and 8c, the outer peripheral surface is formed into a planar decagonal shape, and the inner peripheral surface is formed into a circular shape. A cutout recess 12 into which the piece 5 can be inserted is formed. 13 is the outer ring 8a, 8b, 8
It is a bottom ring that is fitted onto the lid body 1 along with c, and has an annular protrusion 18 formed on its inner circumferential surface that can engage with the recess 17 of the lid body 1.

For the dial-type lid constructed as described above, first, a three-digit number was arbitrarily set to indicate that it could be unlocked, and each outer ring 8 was set to match the number.
The inner rings 11a, 11b, and
11c is fitted into the outer rings 8a, 8b, 8c, and then the mutually fitted outer rings 8a, 8b, 8c and inner rings 11a, 11b, 11c are inserted into the cutout recesses 12 of the inner rings 11a, 11b, 11c. It is assembled by sequentially fitting the flexible piece 5 onto the lid body 1 so that it is located at the position shown in FIG. . At this time, the protrusion 18 of the bottom ring 13
is engaged with the recess 17 of the lid body 1, thereby preventing variations in each ring.

The dial-type lid assembled in this way is used by being fitted onto the opening 16 of the container body 15, which has an annular groove 14 formed therein, as shown in FIG. At this time, the flexible piece 5 of the lid body 1 bends outward as the engaging protrusion 6 protruding on the inside hits the outer peripheral surface of the container body 1. Since there are cutout recesses 12 on the inner circumferential surfaces of the inner rings 11a, 11b, and 11c corresponding to positions 5, the bent flexible piece 5 is fitted into the cutout recesses 12, and thereby the dial type lid is smoothly fitted into the mouth 16 of the container body 15. When the dial-type lid is completely fitted onto the opening 16, the engaging protrusion 6 of the flexible piece 5 will be inserted into the groove 14 of the container body 15 as shown in FIG. . Next, in this state, each outer ring 8a, 8b, 8c is
When the inner rings 11a, 11b, 11c are rotated arbitrarily in the direction of the arrow A as shown in FIG. The circumferential surface completely prevents the flexible piece 5 from deflecting outward. Therefore, even if an attempt is made to pull the dial type lid upward in this state, the flexible piece 5 does not bend outward, so the engaging protrusion 6 of the flexible piece 5 does not come out of the groove 14, and the This ensures that the engaged state is maintained. Therefore, the dial type lid is in a completely locked state and can never be removed by someone who does not know the dial display number to be unlocked.

On the other hand, to release this locked state, move the outer rings 8a, 8b, 8c to align the display section 9 of the predetermined dial display with the position of the protrusion 7 as a mark formed on the flange section 2 of the lid body 1. When rotated, the positions of the notched recesses 12 of the inner rings 11a, 11b, 11c and the position of the flexible piece 5 of the lid body 1 match again, and the flexible piece 5 can be bent outward, thereby preventing the above-mentioned engagement. The engagement between the protrusion 6 and the groove 14 is released, resulting in an unlocked state. Therefore, when the dial-type lid is pulled upward in this state, the flexible piece 5 is fitted into the cutout recess 12 and bent outward, allowing the dial-type lid to be removed from the container body 15 very smoothly.

In this way, in the locking mechanism of the dial type lid of the above embodiment, the engagement and disengagement between the engagement protrusion 6 of the flexible piece 5 of the lid body 1 and the groove 14 of the container body 15 is performed. The dial type lid is locked or unlocked.

In addition, the dial display number that can release the lock state is determined by rearranging the display part 9 of the outer rings 8a, 8b, 8c as appropriate with respect to the position of the notch recess 12 of the inner ring 11a, 11b, 11c, and fitting both rings. It can be changed freely by combining them.

In addition, outer rings 8a, 8b, 8c and inner ring 1
The number of 1a, 11b, and 11c is by no means limited to the three in the above embodiment; in short, it may be at least two or more, and there is no particular limitation on the number.

However, as the number of these rings increases, while it has the advantage of being able to more reliably prevent unlocking, it also has the disadvantage of making the mechanism more complicated and increasing the number of parts. Therefore, it is most preferable that the number of rings is three as in this embodiment.

Furthermore, the number of display sections 9 displayed on the outer peripheral surfaces of the outer rings 8a, 8b, 8c is not limited to 10 as in the embodiment, and the number is not limited at all. or,
In addition to the Greek numerals of the embodiment, the display section 9 also has Greek numerals.
For example, they may be general arithmetic numerals, alphanumeric characters, letters, symbols, etc.

Furthermore, the shape of the combined outer rings 8a, 8b, 8c is by no means limited to the barrel shape of this embodiment.

Furthermore, the number of notched recesses 12 in the inner rings 11a, 11b, and 11c is by no means limited to the one in the embodiment, and two may be formed, for example, at opposing positions on the inner peripheral surface of the inner ring. The point is that at least one or more of them should be formed.

Further, the shape of the lid main body 1 is not limited to the embodiment described above, and the formation of the flange 2 is not an essential condition. In short, it is sufficient that it is formed into a substantially cylindrical shape with an open bottom. Moreover, its material is by no means limited to the synthetic resin of the embodiment. Similarly, the material of the outer ring and inner ring does not matter.

Furthermore, the bottom ring 13 of this embodiment is by no means essential to the present invention.

Further, the number of grooves 14 formed in the mouth 16 of the container body 15 is not limited to one in the embodiment, and is formed in an annular manner as in the embodiment, that is, on the outer peripheral surface of the mouth 16. It does not need to be formed all around.

Furthermore, in this embodiment, a dial-type lid is fitted directly onto the opening 16 of the open container body 15;
This dial-type lid may be fitted over the opening 16 to which the cap 19 is attached, as shown in FIG. 8, for example.

Further, the type of container is not limited to bottles for whiskey, cosmetics, etc., or other piggy banks, and can be applied to all kinds of containers.
