Description

Specification

One-push open-cap mechanism Technical field

According to the present invention, a cap for a container for liquids or particulates, a hook mechanism thereof and a sealing stopper mechanism are integrally formed, and the lid and the stopper can be easily opened together with the hook simply by one-push operation. A mechanism that can be used in a wide range of applications, with a reasonably correlated configuration of mechanism formation and opening operation, eliminating the need for parts and post-processing, and offering high productivity and low cost supply. It is about.

Furthermore, the present invention reliably forms a tight hook mechanism and the tightness of the extraction port, so that the opening operation of the cap and the extraction of the stored items can be performed appropriately without difficulty, and the outer shape of the container or the cap can be reduced. It relates to a safe mechanism that eliminates the need for damaging irregularities, enables a flat and clean design, and prevents infants from accidentally removing hooks. BACKGROUND ART Conventionally, there has been a "one-touch-and-cap" which employs a hinge structure by integral molding. For example, there is 2-4 5 2 6 6. In this structure, it was necessary to project the hook part to the outer shape of the container or cap, and the structure of the extraction port and the stopper was a mechanism to move up and down in the direction perpendicular to the hinge line. To open these caps, it is necessary to grasp the container with one hand, squeeze the hook with the thumb of the other hand, remove the hook, and open the cap to the expanded state. Arm also protrudes greatly It was a structure. In addition, the projecting shape of the hook had the danger that infants could accidentally open it.

There are some cases, such as the actual fairness 7- 5 4 1 1 9, where the structure is extremely complicated and the manufacturing process is difficult. This plan uses the principle of the principle of the shaft, and for that reason, the supporting member which is the pivot of the shaft is an essential requirement.

In the case of a cap using the seesaw principle, it is impossible to form a reliable hook shape that forms a wedge shape on the rotation side in order to prevent the opening operation. In fact, looking at this plan, only a small recess that does not function as a hook is formed at the tip of the rotating side in the appearance.

The basic condition of the cap is to avoid unnecessary opening of the cap and keep the stored items safely stored, which is also an imperfect plan.

In addition, in the case of adopting the seesaw principle, an indispensable support member is formed on the lid side, and further, it is necessary to provide a receiving part on the cap body side to fix the support member. The inside of the lid has an extremely complicated appearance, and it describes a shape that would not be possible due to the molding process. This is an extremely low feasibility plan.

There are other plans for the "One Touch Open Cap" that require parts and post-processing, but all of them have difficulty in productivity and operability, and their use is limited.

In the past, the applicant has applied for a lid opening mechanism PCT / JP94 / 00167, and has proposed a cap in this. This cap was excellent in terms of the basic principle of the mechanism for pressing and opening the cap body and the lid, but the imperfections remained in the structure of the outlet and stopper for the stored items.

In other words, the structure of the extraction port and the stopper of the cap was vertical to the lid, and did not match the forward operability of the lid when the lid was opened.

In order to enhance the opening effect of the lid, fatal difficulties were inherent, for example, the fitting of the extraction port and the plug had to be loosened at the expense of the sealing performance of the plug. DISCLOSURE OF THE INVENTION The cap of the container requires a firm hook mechanism to prevent unnecessary opening of the lid, and has a sealing plug function to reliably keep the storage in the container tightly closed. When opening the stopper, grasp the container and release the hook simply by pushing with one finger with the same hand. There is no need to provide a fulcrum, a roller mechanism, etc., and there is no need for irregularities in the outer shape.Since the mechanism and configuration are simple with only the cap body and lid, parts and post-processing are also unnecessary. It is desirable to supply highly functional products at low cost and make them widely available.

In view of the above, the cap mechanism according to the present invention uses an elastic material, has a hinge structure, and provides an integrated push-open cap mechanism for a container. The cap body and the lid are formed so as to have a common directionality in the pressure direction, the opening operation direction of the hook and the stopper, and the direction of extraction of the stored items. A hook mechanism is provided, and the container extraction port and the stopper are formed in the cap body and lid in such a way that they are each inclined at the same angle in the direction of rotation, and two slits are attached to the cap body. The hinge section is provided so as to reach the lid section from the side, and a bent section is provided at each end of the two slits of the lid section, and the two-slit and two-slit cap body sides and The part surrounded by the part reaching the lid is the cap pressing and releasing operation part.

Further, when the pressing operation portion is pressed in the turning direction, the lid portion advances in the turning direction to release the hook, and at the same time, the plug portion tilted in the turning side direction is formed at the same tilt angle. The diagonal distance between the hinge part on the cap body side and the bent part of the lid part is extended by linearizing the pressing part, and the lid is moved by the pressing force. The lid and the plug are opened around the bent part of the part, and the extraction of the items stored in the container can be appropriately realized in the rotation direction It is characterized by being able to function.

Further, in the above cap mechanism, a second bent portion is provided on the lid side at an intermediate portion between the lid side hinge portion and the bent portion. The second bent portion can be largely opened by turning it over, so that the plug formed by inclining in the direction of rotation can be completely opened from the extraction port formed at the same angle of inclination. It is also characterized by being able to reliably extract the items stored in the container in the proper direction.

By pressing the pressing operation unit 5, the lid is pressed in the rotating direction to release the wedge-shaped hook, and the pressing operation unit 5 is deformed inward of the cap body, and the pressing operation unit is linearized. As a result, the diagonal distance between the hinge part 4 on the main body side and the bent part 7 of the lid part is extended, and as a result, the plug part 11 is formed from the extraction port 10 formed at the same inclination angle in the rotation direction. It shows a state of being pushed forward and opened upward.

In the above embodiment, the cap body and the lid are each formed with a male and female hook mechanism that forms a wedge on the rotation side, and the extraction port 10 and the stopper 11 are each turned by the lid. It is formed at the same angle of inclination with respect to the direction of movement, and has a rational structure with a common directionality for the locking function of the hook and plug, the sealing function, and the opening operability. .

Further, the shape, position and quantity of the extraction port 10 and the stopper 11 can be set as necessary according to the contents of the container and the intended use.

As long as the shape of the pressing / opening operation section 5 and the lid section 2 is kept parallel to the hinge section 4, it is also possible to freely develop the design into a curved surface or the like.

Furthermore, the shape of the fitting portion 13 with the container or the like is not limited to a spiral shape and can be expanded to other shapes that can ensure the necessary sealing performance, according to the conditions of the stored goods and the intended use. . The hooks 8 and 9, the pressing unit 5, the container and the cap body 1 and the lid 2 do not require any irregularities in the external shape, so that a flat and simple design can be realized. Open accidents due to misoperation by infants, etc. can also be avoided.

In this embodiment, the cap body 1 and the lid 2 are provided with a simple outer shape with no irregularities, a solid hook mechanism, and an extraction port 10 formed to be inclined in the rotation direction, and It can be composed of only the plugs 11 formed at the same angle, and the mechanism such as the seesaw fulcrum and the roller is unnecessary, and the minimum necessary mechanism for forming and opening the cap is required. It can be configured with a common common direction and can be integrally formed, and no separate parts or post-processing is required. This is a cap mechanism that can be produced extremely easily and has wide applicability. The present invention relates to a cap mechanism for a container such as a liquid powder, a wedge-shaped hook and a sealing stopper mechanism, and a method of forming the same and its opening operability, and has a hinge portion.
