Self-actuating closure mechanism for closable objects

The present invention is in the field of mechanical technology, and more particularly in relation to self-actuating closure mechanisms for objects having components that are closable with each other, and more particularly, includes a self-actuating closure mechanism that is rotatably coupled. This includes, but is not limited to, embodiments in the form of a covered container having a self-closing mechanism that is operated to automatically mechanically lock and seal the container regardless of how the lid is placed on the container.

This application claims to be based on (1) U.S. Provisional Patent Application No. 61/087,814, filed on August 11, 2008, and U.S. Provisional Patent Application No. 61/107,546, filed on Oct. 22, 2008. And (3) the priority of US Provisional Patent Application No. 61/141,395, filed on Dec. 30, 2008. The complete disclosure of each of these U.S. Provisional Patent Applications is incorporated herein by reference.

An example of an object having a rotatably engageable closable assembly is a jar having a threaded cap. Common kitchen jars are often dropped and broken because the previous user did not properly screw the lid.

Currently, most containers use a standard threaded locking/seal mechanism or latch, both of which require a specific force to achieve locking and sealing. In the case where the required force is not applied correctly or completely, two main problems may arise: (1) the seal cannot be achieved, thus possibly jeopardizing the contents of the container, or (2) the lock is insufficient, so When the container is picked up by the cover, the container and contents may be exposed to risks.

One prior solution to this problem is to provide a container having a lid with a pressure clip closure. However, the press-fit clip cover can only be used for lightweight containers and contents. It must be effectively pressured off. At the same time, most clips do not provide a sufficient seal.

Therefore, there is a need for a self-sealing container that provides an effective and strong seal for a wide variety of contents. More generally, there is a need for more modern closures that are not only self-actuating and convenient, but also provide a strong and secure closure.

It is an object of the present invention to provide a self-actuating closure that can be operated in a convenient and straightforward manner and that provides an effective and strong seal for a variety of container contents when incorporated into a container. Other required attributes include:

Preferably, the mechanism is automatically closed in a smooth and predictable manner to avoid an indeterminate "blocking" or "stagnation" state in which the closure suddenly stops fully engaged.

Preferably, in addition to a specific, intended detachment operation, the closure engages in a manner that provides strong and positive resistance to detachment when subjected to force and motion.

Preferably, the detachment operation involves forces and actions that are different from the forces and actions resulting from daily storage and handling.

Preferably, the closure mechanism can comprise a positive seal for solid, liquid and/or gaseous contents.

In certain embodiments, the present invention utilizes mutually attracting or repelling elements (e.g., magnets) on a lid and/or body (tank) of a container to attractably engage the body and the lid and to initiate engagement upon engagement. These objectives are partially achieved by mechanical interlocking of the joint assembly in a locked position. In these embodiments, the lid simply needs to be placed near the top of the can and released. The closure mechanism shown can be adapted to any device having a closure that is operated by rotation. By the same principles shown, the mechanism can be adapted to non-rotating embodiments, such as a closure that slides into place in a straight position, an embodiment with a latch, and other closures.

Other aspects and advantages of the invention will appear from the drawings and the detailed description.

For a fuller understanding of the present invention and its advantages,

The following is a description of an alternative embodiment of the invention. The embodiments are merely illustrative, and the invention defined by such technical solutions is not limited to the specific examples shown. For example, certain preferred embodiments are described with respect to an implementation having particular magnetic attraction elements, pins, and channels, but it should be understood that the following disclosure is intended to enable those skilled in the art to readily apply the aforementioned teachings. Other commonly available hardware and materials. The specific features of any particular embodiment are not to be construed as limiting the scope of the claims.

The particular embodiments presented herein for the purpose of illustrating the invention may be practiced in the context of a rotary engagement machine for a container, such as a container used in a kitchen. There are of course also embodiments other than containers in which the mutually enclosed components are engageable by a rotational action.

An illustrative object having a rotary joint closure in accordance with an embodiment of the present invention, in this case the object 1 shown in Figure 1, comprising a body 2 and a cover 3.

Reference will now be made to the "top" of the body 2, and such reference will be the end of the cover 3 facing the body 2 in a mutually closed position. Similarly, reference to the "bottom" of the lid 3 refers to the portion of the body 2 that faces the lid 3 in a mutually closed position. The term "axis" as used herein shall refer to the axis of rotation defined when the cover 3 is rotated to engage/disengage the body 2. "Axial" will mean to align with the axis, while "radial" and / or "circumferential" will refer to a position in a plane perpendicular to the axis.

In the embodiment shown in Figure 1, the object 1 is configured as a container having a hollow interior and is therefore sometimes referred to as "container 1". The lid 3 is shaped to engage the body 2 and is rotatable when engaged therewith. The cover lip 61 descends circumferentially downward from the top of the cover 3 to form a cylindrical structure that is shaped and dimensioned to fall over the upper portion of the body 2 and receive the upper portion.

Figure 2 also shows the container 1 in an exploded partial view.

At least one (and three in the case of this embodiment) is fixedly disposed on the body 2 in a shape similar to the first interlocking member of the first interlocking member 4. In the embodiment shown in Figure 1, the first interlocking member 4 is generally in the shape of an inverted circular segment (the curved bottom surface near the region 7 has some flattening at which it is nearly horizontal), which The upper portion of the body 2 projects radially (or has a radial extent relative to the body 2) and is oriented such that its generally flat upper surface 12 slopes downwardly, in this embodiment when viewed from the side and outside of the container 1. Tilt from left to right. In this embodiment the three first interlocking members comprise a first interlocking member 4 and two other corresponding similar interlocking members (visible in Figure 1C but not separately referenced), which are similarly spaced approximately 120 degrees apart. The circumference is fixedly disposed around the outer circumference of the body 2.

There is at least one, and in the case of this embodiment, three second interlocking members similar in shape to the second interlocking member 5 are fixedly disposed on the cover 3. In the embodiment shown in FIG. 1, the second interlocking member 5 has the shape of a cylindrical pin that is radially oriented with respect to the axis of the cover 3 and protrudes inwardly from the inner circumference of the outer lip 61 of the cover (or There is a radial extent relative to the cover 3). In this embodiment, the three second interlocking members include the second interlocking member 5 shown in FIG. 1 and two other corresponding similar interlocking members (visible in FIG. 2 but not separately referenced), which are similarly similarly The interval of about 120 degrees is circumferentially fixedly disposed on the inner circumference of the outer lip 61 of the cover.

The cylindrical pin shape of the second interlocking member 5 (and its circumferential corresponding member) can be rotationally engaged with the bottom side of the first interlocking member 4 (and its circumferential direction) when the cover 3 is closed on the body 2 and rotated relative to the body 2. Corresponding component). As can be seen from FIG. 1E, this rotational engagement has a rotationally defined region of one of the interlocking joints 6 adjacent the generally flat horizontal portion (in region 7) of the underside of the first interlocking member 4, wherein in the region of the interlocking joint 6 The interlocking portion 8 of the second interlocking member 5 is disposed in opposition to a region 7 (of the first interlocking member 4), that is, a portion of the substantially flat horizontal bottom side region of the first interlocking member 4.

Furthermore, there is at least one pair of mutually attracting (or repelling) elements (9, 10), the opposing elements of which are respectively disposed on the body 2 and the cover 3 and positioned thereon such that when the cover 3 is opposite the body 2 The strongest suction of each other when rotating The lead (or repulsive) position corresponds approximately to the rotational position of the cover 3 and the body 2 in the region of the rotationally positioned interlocking engagement 6. In this embodiment, the mutually attracting/repelling elements are magnets, and preferably strong rare earth magnets. The N/S polarity of the magnets is indicated by light/dark shadows (polarity is irrelevant as long as the polarities are treated consistently). In the illustrated embodiment, the three magnets 9, 9' and 9" are circumferentially disposed around the cover 3 at intervals of approximately 120 degrees. The opposing magnets 10, 10' and 10" are circumferentially disposed at the base at similar intervals and radii. 2 on. (The base 2 may also have additional magnets around its upper periphery, such as magnets 21, 21' and 21" that are oriented by N/S relative to the N/S orientation of the other base magnets 10, 10' and 10" In the direction of the body to repel rather than attract the magnets 9, 9' and 9"; such optional, relatively oriented magnets will be discussed later in this disclosure. The magnet configuration shown here (and involves more A similar arrangement of the number of fewer magnets can also be reversed between the cover and the base. In the embodiment shown, pairs of magnets are used. However, the magnets and unmagnetized magnets that will be understood by those of ordinary skill will be appreciated. Combinations of materials may be used in an equivalent manner.

As can be seen from the various views of Figure 1, the first and second interlocking members 4 and 5 are also in an interlocking position when the magnets 9 and 10 are aligned. In the embodiment shown, this occurs when all of 4, 5, 9 and 10 are approximately aligned, but the interlocking pairs 4 and 5 do not have to be vertically aligned with the magnet pairs 9 and 10.

Furthermore, it is preferred to have at least one bevel 11 forming the bottom of an insert which extends at least partially around the outer periphery of the body 2. The inner peripheral wall of the region of the insert above the bevel 11 comprises a first interlocking member 4 as a radial projection into the insert. The bevel 11 is inclined with respect to the top of the body 2 to be inclined in the direction of the region of the interlocking joint 6 and extends below the first interlocking member 4 in this region of the interlocking joint 6 and has sufficient clearance to accommodate the second Chain 5 . There are three circumferential bevels in this embodiment, including the bevel 11 and the other two corresponding similar bevels (which can be seen in the various views of Figure 1), also spaced apart by approximately 120 degrees. Furthermore, in this embodiment (but not necessarily in the present invention) the bevel 11 (and each of the other two corresponding bevels) comprises two sections, one on each side of the first interlocking member 4, each section surrounding the An interlocking member 4 is symmetrically inclined and extends below the bottom side of the first interlocking member 4. The three bevels collectively define a generally fan-shaped insert having a varying depth of depth around the upper periphery of the body 2. It can be inferred from the above that in this embodiment, the first interlocking member 4 or the like protrudes from the side faces of the body 2 into the sector-shaped insert, and the three regions of the maximum bevel depth are placed approximately in the first interlocking member 4 and the like. Underneath, a gap is provided for the second interlocking member 5 and its corresponding two other cover interlocking members.

The bevel 11 is positioned on the body 2 when the cover 3 is attracted from the rotational position to the body 2 to receive the second interlocking member 5 from above, wherein the second interlocking member 5 approaches a portion of the inclined surface 11 from above the inclined surface 11. Note that the present invention will work without the bevel 11 . However, it is preferred to have a bevel 11 because it helps to participate in assisting both gravity and magnetic forces to convert the downward movement of the cover into a rotation in the locking direction, rather than relying solely on magnets or other attracting/rejecting elements to induce this. Rotate.

The respective shapes of the interlocking members 4 and 5 - in this embodiment, the interlocking member 4 as an inverted substantially circular segment shaped member having a flat side flat region and the shape of the second interlocking member 5 as a cylindrical pin It helps the cover 3 to be smoothly closed on the body 2. The upper surface 12 of the first interlocking member 4 and the lower surface 13 of the second interlocking member 5 are shaped such that the surfaces 12 and 13 are further in the case where the surfaces 12 and 13 are in contact with each other during the closing of the cover 3 against the body 2. Cooperating together and (respectively) sliding against each other as the cover 2 and the body 3 rotate. The sliding is in a direction corresponding to the closer engagement of the cover 3 and the body 3. The shapes of the surfaces 12 and 13 further cause the first interlocking member 4 and the second interlocking member 5 to slide away from each other at a position of relative rotation and compression of the cover 3 and the body 2 above the inclined surface 11 (then the second interlocking member 5) Falling onto the ramp 11 and starting to engage will be described herein with respect to the ramp 11).

The preferred magnets 9, 9' and 9" will be in close proximity to the magnets 10, 10' and 10" in the closed position, but preferably the opposing magnet surfaces are not physically in contact. This smaller separation helps the lid 3 maintain a positive pressure against the base 2 when the container 1 is closed and aids in sealing.

The base 2 also has a central opening 32 therein defining an interior space or volume of the body 2 (typically where the object 1 is, for example, a kitchen container having an interior for its contents). The preferred cap 3 also has a cylindrical inner lip 31 disposed at the bottom of the cap 3 and shaped to fit snugly into the peripheral wall of the central opening 32 of the base 2 to reduce friction.

When the cover 3 is close to the body 2, the cylindrical inner lip 31 engages with the central opening 32 of the body 2. Assuming that the lid 3 and the body 2 are approximately erect, as the lid 3 is released, it tends to fall toward the body 2 (first in most cases primarily due to gravity), preferably by the cylindrical inner lip 31 into a concentric position. When the cover 3 is in proximity to the body 2, the magnets 9 and 10 (and their corresponding radial counterparts) and/or the magnets 9 and 21 (and their corresponding radial counterparts) will be close enough to create a significant interaction. The magnets 9 and 10 attract each other, and the magnets 9 and 21 repel each other. In either case, the attraction and/or repulsion pushes the magnets 9 and 10 closer together, and the interlocking members 4 and 5 push toward the locked position while attracting the cover 3 close to the body 2.

If the second interlocking member 5 contacts the bevel 11, these forces tend to pull the second interlocking member 5 into position below the first interlocking member 4. On the other hand, if the second interlocking member 5 abuts the upper surface 12 of the first interlocking member 4 in this procedure, the second interlocking member 5 will slide down the slope of the top surface 12 of the first interlocking member 4 and fall on the inclined surface 11 Once again, it is introduced into the locked position below the first interlocking member 4. When in the locked position, the approximately flat interlocking portion 8 on the lower surface 7 of the first interlocking member 4 ensures that the lid remains locked even if a container to which the lid is attached is picked up from the lid.

Except by pulling the second interlocking member 5 from below and avoiding the first interlocking member 4 (i.e., resisting the strong magnetic force that tends to align the interlocking members) and then pulling the cover 3 away from the body 2 (again resistance tends to In addition to the specific twisting and pulling disengagement action of the magnetic force that pulls the lid and body together, the container in this embodiment strongly and reliably resists removal of the lid. A pure pull will not remove the cover 2. A rocking force, a lateral force or a pure torsion force cannot remove the cover 2.

Preferably, the repulsive magnets 21, 21' and 22' are circumferentially disposed about the body 2 at an interval of 120 degrees and are centered at equal distances between the magnets 10, 10' and 10". One or more of this In embodiments where additional magnets are used, the body magnets are arranged in an alternating polarity to form an NSNSNS pattern around the body (in the case of three sets of magnets). Preferred bevels 11 The intersection with the counterpart, i.e., its highest point 71, etc., is in a position approximately aligned with the magnets 21, 21' and 21", i.e., where the magnets 9, 9' and 9" will experience approximately the maximum repulsive force. It is especially effective when providing a true, automatic locking action without indeterminate state, blocking, "stagnation" or dead point.

Further, a seal can be provided between the cover 3 and the base 2. In the embodiment shown, this seal takes the form of an O-ring 41 which is located at the base of the cylindrical inner lip 31 where it connects the lid 3 and when the lid 3 is in the closed position on the base 2 Abutting the chamfer 42 on the base 2. A flat sealing ring or disc can be used instead of an O-ring. The O-ring 41 is sized and placed such that it is approximately optimally compressed to seal when the assembly of the container 1 is in a fully locked position.

The base 2 may further include a resilient pad 51 on the bottom of the base 2. This pad promotes one-handed use of the container 1. The pad provides sufficient friction against a surface such as a table or counter to overcome the attraction of the magnets when the user twists the cover so that the user does not need to hold the base with the other hand.

It is not necessary to use three cover magnets. One or more, up to any number of magnets can be provided. However, in embodiments of this type in which repelling magnets are also used, the preferred number of body magnets is twice the number of cover magnets (or vice versa) so that their polarities are alternately and equally spaced. And with corresponding interlocking elements and bevel elements for each mutual attraction pair as needed. Presently preferred embodiments have three illustrated lid magnets and six body magnets.

The ramp 11 and the first and second interlocking members 4 and 5 and associated structures can be interchanged and/or reconfigured between the lid 3 and the base 2 of the container 1 for equivalent operation. Similarly, the cover 3 can be adapted to fit within the central opening 32 of the base 2 rather than being mounted over the top of the outer side of the body 2. Those skilled in the art will appreciate other variations that have a similar nature.

A number of other embodiments can be developed for a generally rotating closure embodiment in accordance with the principles of the present invention.

For example, in an alternate embodiment, as shown in FIG. 3, three cover bar magnets 309 are radially oriented and positioned in the inner lip 361 of the cover 303; the body 302 has six sets of ramps 311, the bevels 311 has an interlocking member 304 centered above the lowest point of the ramp 311 and a body magnet 310 radially oriented below the interlocking member 304 in the wall of the body 302. Thus, in this embodiment, the magnets 309 and 310 are joined from the side rather than from the top (or repelled in the case of one of the variations of this embodiment). The rod magnet 309 functions as both the locking pin (5) and the cover magnet (9) of the previously discussed embodiment, i.e., the magnet 309 engages the body ramp 311 and provides a strong attraction to the magnet 310 once under the interlock 304. And thus provide a mechanical lock.

Although the design of the embodiment shown in FIG. 3 is generally satisfactory, the tilt of the upper surface of the first interlocking member 4 of the embodiment shown in FIG. 1 has one advantage over the corresponding interlocking structure shown in FIG. Because it avoids the possibility of a "dead point" in a self-closing in the embodiment of FIG. 3 when the cover 303 is initially placed, such that the rod magnet 309 is extremely close to the top of the first interlocking member 304. The first interlocking member 304 is approximately at the topmost height of its upper surface. The uninterrupted and continuous tilting of the top surface 12 of the first interlocking member 4 in the embodiment of Fig. 1 avoids this particular condition.

4 shows another alternate embodiment having eight pairs of mutually attracting magnets, including four pairs of magnets 609, 610 in an NS pairing orientation that alternate around the circumference of the cover 603 and body 602, and four pairs oriented in opposite orientations. Magnets 622, 621. The first four pairs 609, 610 are respectively centered above the linkages 604, 605, and the second four pairs 621, 622 are respectively centered on the topmost region of the slope 611.

It will be apparent that various embodiments of the present invention can be used with any type of rotary closure that does not have to be associated with a cylindrical container, such as a gas canister or other packing cover, venting hood or the like.

Moreover, the principles of the present invention may also be adapted to non-circular geometries in which a channel similar to ramp 11 is linear and has, for example, two parallel alternating pairs of magnets rather than a ring configuration.

Similarly, as described above, in a rotary joint embodiment, the first and second interlocking members 4 and 5 need not be aligned with the magnets 9 and 10, but may be opposite to the axis of a ring mechanism or relative to a linear mechanism. The length is offset at any angle as long as it is positioned such that the second interlocking member 5 is aligned with the first interlocking member 4 when the magnets 9 and 10 (or corresponding mutual attraction elements) are aligned, in this case the beveled surface 11 (or corresponding element) The deepest point of the ) will also be moved to align with the locked position defined by the first and second interlocking members.

In addition, interlocking members 4 and 5 can be interchanged with other interlocking elements known to those skilled in the art, including but not limited to hooks, latches, interlocking slots, and the like.

The two embodiments shown in detail here have mutually attracting elements, in which case the magnets are arranged differently, in one case joined along one radius and in the other case axially joined. These are only two of the many operative configurations of mutually attracting or repelling elements, and those skilled in the art will readily appreciate that other forces are provided by rotation or sliding to attract the closures together and move them into the locking pair. The configuration of the quasi-relationship. As mentioned above, a combination of magnets and unmagnetized magnetic materials can also be used as an alternative to magnet pairs.

As explained above, a self-actuating closure in accordance with the present invention overcomes the shortcomings of the prior art in various respects. It only requires the placement and release of the lid (or other closure element) to automatically lock and seal it. It eliminates the need to manually apply specific forces to achieve a lock and seal and provides a reliable and effective seal for a variety of containers and contents. It can be automatically closed in a smooth and predictable manner to avoid "blocking" or "stagnation" in which the closure suddenly stops fully engaged. It may be engaged in a manner that provides a strong and positive resistance to detachment other than detachment by a particular detachment operation involving forces and actions other than those resulting from daily storage and handling. The closure mechanism can easily incorporate a positive seal for solid, liquid and/or gaseous contents.

Thus, it is apparent that the present invention satisfies the foregoing objects and provides some advantages over the prior art in terms of use and efficiency. Although the present invention has been described in detail, it is understood that the invention may be
