Description

[0001]
[Technical field to which the invention belongs]
This invention integrally forms a cap such as a container for liquid or powder and its hook mechanism and a sealing plug mechanism, so that it can be easily opened only by one push operation of opening the lid and plug together with the hook. The present invention relates to a cap mechanism that can be used in a wide range of applications, with the mechanism formation and the opening operation configured with a reasonable correlation, eliminating the need for parts and post-processing, and being excellent in productivity and enabling low-cost supply.
[0002]
In addition, the present invention reliably forms a tight hook mechanism and a sealing property of the extraction port, allows the cap opening operation and the extraction of stored items to be carried out reasonably, and unevenness that impairs the outer shape of the container and the cap. This also relates to a safe mechanism that enables a flat and neat design and prevents an infant from accidentally removing the hook.
[0003]
[Prior art]
Conventionally, there is a “one-touch open cap” that employs a hinge structure by integral molding. For example, Japanese Utility Model Publication No. 2-45266 may be mentioned. This structure requires the hook portion to protrude from the outer shape of the container or cap, and the structure of the extraction port and the stopper is a mechanism that moves up and down in a direction perpendicular to the hinge line.
[0004]
In order to open these caps, it is necessary to grasp the container with one hand, remove the hook with the thumb of the other hand and remove the hook, and widen the cap in the unfolded state. It was a structure that sticks out. In addition, the protruding shape of the hook portion has a risk that an infant or the like may accidentally open it.
[0005]
There is a proposal such as a real fairness 7-54119 in which the structure is extremely complicated and the manufacturing process is difficult. This proposal uses the seesaw principle, and for that purpose, a support member that becomes a seesaw fulcrum is an indispensable requirement.
[0006]
In a cap using the seesaw principle, it is impossible to form a reliable hook shape in the form of a wedge on the rotating side in order to prevent the opening operation. In fact, when this plan is viewed, only a small concave portion that does not have a hook function is formed at the tip on the rotating side.
[0007]
The basic condition of the cap is to avoid unnecessary opening of the cap and to store and maintain the stored items safely, which is also an incomplete proposal.
[0008]
Moreover, in the said plan which adopted the seesaw principle, an indispensable support member is formed on the lid side, and in order to fix this, it is necessary to provide a receiving part on the cap body side. The internal structure has an extremely complicated aspect, and a shape that is considered impossible to be removed due to molding is described, and the feasibility is extremely low.
[0009]
There are other proposals for "one-touch open caps" that require parts and post-processing, but all of them have difficulty in productivity and operability, and their application range is limited.
[0010]
The applicant has previously filed a lid opening mechanism PCT / JP94 / 00167 and proposed a cap therein. This cap was excellent in terms of the basic principle of the operation mechanism for pressing and releasing the cap body and the lid, but imperfections remained in the structure of the extraction port and plug of the stored item.
[0011]
That is, the structure of the extraction port and the stopper of the cap has a vertical structure with respect to the lid, and does not match the forward operability of the lid by the lid opening operation.
[0012]
In order to enhance the opening effect of the lid, a fatal difficulty is inherent, such as loosening the fitting between the extraction port and the plug portion at the expense of the sealing performance of the plug portion.
[0013]
[Means for Solving the Problems]
The cap of the container requires a solid hook mechanism to prevent unnecessary opening of the lid part, and has a sealing plug function to securely keep the contents in the container sealed, and grips the container when the hook and the plug part are opened. It is necessary to release the hook by one push with the finger of the same hand, and at the same time to easily open the plug part and the lid part at the same time. In addition, there is no need for irregularities in the outer shape, and by using a simple mechanism and configuration with only the cap body and lid, it is possible to form a single unit with no parts or post-processing, and to supply high-performance products at a low cost. It is desirable to make it widely available.
[0014]
Therefore, the cap mechanism according to the present invention is a one-push open cap mechanism for an integrally formed container using a flexible material and having a hinge structure. And the opening operation direction of the plug portion and the extraction direction of the stored item are formed to have a common directionality, and each of the cap body and the lid portion is provided with a male and female hook mechanism that forms a wedge shape on the rotation side of the lid, In the cap body and the lid part, the extraction port and the plug part of the stored item are formed at the same angle in the rotation direction, respectively, and the two slits are formed from the cap body side across the hinge part to reach the lid part Provided are bent portions at the ends of the two slits of the lid portion, and a portion surrounded by the two slits and the cap body side of the two slits and the portion reaching the lid portion is defined as a pressing release operation portion of the cap.
[0015]
Furthermore, when the pressing operation part is pressed in the rotation direction, the lid part advances in the rotation direction and the hook is released, and at the same time, the plug part inclined in the rotation side direction has an extraction port formed at the same inclination angle. The diagonal distance connecting the hinge part on the cap body side and the bent part of the lid part is expanded by the straightening of the pressing operation part, and the bent part of the lid part is pushed by the pressing force. The lid portion and the stopper portion are opened around the axis, and the extraction of the stored item in the container can be appropriately realized in the rotational direction.
[0016]
Further, in the cap mechanism, by providing the second bent portion on the lid portion side at the intermediate portion between the lid portion side hinge portion and the bent portion, the lid portion is folded by the press release operation. It can be opened greatly from the curved part in the inverted state, and the plug part formed by inclining in the direction of rotation along with this is completely opened from the extraction port formed at the same inclination angle, and stored in the container The feature is that the product can be extracted in the proper direction.
[0017]
