Description

The present invention is used externally to a PET bottle container, and the cap opens with a slight force by applying a lever when opening the lid, and uses the function of an elastic body when closing the lid to achieve its purpose. . .

In recent years, water bottles with lids that open using an elastic body or external caps have come out, but to date, I have not seen any that have lids that close, and the only ones that are known are: There is Patent Document 1.
However, issues include whether the surface is structurally clean and whether it can be easily repaired in the event of a problem.
Further, in Patent Document 2, the lid is opened using a lever, but the lid is closed manually.

By turning it to the side where the body is not attached, it contacts and tilts the hinge (11), and when the lid is closed, the elastic body A (120) or the elastic body on the side moored to the rotating part (30) and the neck main body (66) The reaction of B (127) will be used, so by further turning the lever (32) in the rotational direction, the protrusion A (56) or protrusion B (58) will come off the hinge protrusion (13), and the above-mentioned The lever (32) of the rotating part (30) is pulled back to the front side and is biased to close the lid, and at the same time, the elastic body A (120) returns to its natural length. Also, the features of each part are that the cap (3) has a lever locking hole (5) on the lower front side, and a torsion spring hole A (9) on the lower side of the rear extension (7). The end hole (17) of the end (15) of the hinge (11), which is provided vertically from the extension (7), is a hinge that protrudes from the back surface of the neck main body (66) having an open upper end. It is hinged to the hinge mounting hole (74) of the connecting part (72), and a hinge convex part (13) is provided at the center of the inside of the hinge (11) of the cap (3), and the rear outer peripheral green part is connected to the rear wheel (54). ) A stopper A (60) and a stopper B (62) protrude diagonally outward from the protrusion A (56) and protrusion B (58), respectively, and are located below the connecting rear wheel (54). has a semicircular opening (50), an arc-shaped inner circumferential convex portion (52) of the rotating portion protrudes from the inner circumferential surface of the remaining portion (42) of the rotating portion (30), and fasteners A (46) are provided on the lower side of both ends. ) A fastener B (48) is attached, and a lever (32) equipped with a hook (34) is provided on the front side of the outer periphery, and when the neck main body (66) is fitted into the rotating part (30), the outer periphery A recess (70) on which the rotary inner convex ring (52) is pivotally supported is provided on the lower side of the surface, and an elastic body groove (84) in which a stretchable elastic body fits is provided on the lower side of the neck main body (66). A rear protrusion (76) is provided at the rear lower end of the outer peripheral surface, a torsion spring hole B (78) is provided on the upper surface, a fastener C (80) and a fastener D (82) are provided at both left and right ends, and the lower end (86) is provided. A bottle connecting female screw (88) that screws into the male screw (154) of the plastic bottle container (150) or water bottle container (170) is formed on the inner peripheral surface of the plastic bottle automatic opening/closing device (1). In the narrow mouth type (190), the cap (3) and the rotating part (30) have the same outer diameter, and are protruded from the back side of the lever (32) provided on the front side of the outer periphery of the rotating part (30). A compression coil spring (140) inserted between the small protrusion A (38) and the small protrusion B (40) attached so as to face directly on the front outer peripheral side of the rotating part (30), The type suitable for a small opening neck (152) such as a container (150) and the wide mouth type (200) are suitable for the neck body (66) and the rotating part (30) relative to the cap (3) fitted to the neck body (66). ), the outer diameter of the lever (32) on the outer peripheral surface of the rotating part (30) bulges out, so that the lever (32) on the front side of the rotating part (30) is shielded, The distance from the elastic body groove (84) provided on the neck main body (66) is widened, and the area around the small protrusion A (38) protruding from the back side of the lever (32) is partially opened. , a small protrusion B (40) is provided on the lower side of the recess (70) of the neck main body (66) so as to directly face the small protrusion A (38), and a plate spring (145) is interposed therebetween.

The following effects can be expected from the present invention.
Without touching the cap, push down the lever that has a hook that engages with the lever locking hole on the front of the cap, and when the hook is released, turn the lever to the left or right so that the protrusion comes into contact with the hinge and the cap tilts. The bottle cap opening/closing device of the present invention is a device that opens and is significantly different from (Patent Document 2) in that the hinge is provided with an elastic body A, and the elastic body is moored to the rotating part and the neck body. However, this elastic body is not limited to metal springs, but can also be applied to elastic bodies such as rubber cords, and if the elastic body is made of metal, the rotating member becomes a barrier and compressive strain is less likely to occur from the natural length state. Even if you try to turn it any further, it won't turn, and the lever is basically turned only in the opposite direction to the moored side, so it functions as a lock and relies on the elastic body to close the lid after completing its purpose. The pulling force returns the lever to the front, and at that time the elastic body on the hinge rises toward the neck, making it possible to close the lid or close it with minimal assistance. Since the structure itself is simple, the cap and rotating parts can be replaced, and the elastic body of the rubber cord can be used to create a wide range of originality by replacing not only plain items but also items with characters. It is possible to provide a narrow-mouth automatic cap opening/closing device, a wide-mouth automatic cap opening/closing device, and a container set.

For these reasons, the structure is extremely simple compared to (Patent Document 1), and there is nothing blocking the drinking spout, making it easy to drink comfortably, and the bottle cap opening/closing device is easy to clean and prevents any malfunctions. It is very easy to treat when it happens.

Embodiments of the present invention will be described below based on the drawings.

First, FIGS. 1 to 3 will be explained. Figure 1 shows a narrow-mouth type (190) of a cap opening/closing device (1) that is twisted with a small-opening neck (152) of a general PET bottle container (150), and is different from (Patent Document 2). , a small protrusion A (38) is provided on the back side of the lever (32), and a small protrusion (40) is protrudingly provided on the outer peripheral surface of the rotating part (30) so as to directly face the small protrusion A (38). The side surface of the rotating part (30) has a large opening (50) from the remaining part (42) to the hinge connecting part (72) and the rear protrusion (76). The inner peripheral convex part (52) of the rotating part is pivotally supported in the concave part (70) of the neck main body (66), and a fastener is attached to the side surface of the rear protrusion (76) which is provided at the rear lower end of the neck main body (66). A tool C (80) is provided, and in the enlarged view of FIG. 2(a), a small protrusion B is provided from the rotating part (30) at a position directly facing the small protrusion A (38) on the back side of the lever (32). (40) protrudes, and the compression coil spring (140) is fitted into it. At this time, depending on the strength of the compression coil spring (140), the hook (34) protruding from the lever (32) It has a structure that securely locks into the lever locking hole (5), and in addition, the amount of change in the elastic body of the iron coil that locks between the rotating part (30) and the neck body (66) provides the lid closing function. In addition to this, it also brings about the effect of keeping the lid closed, and these elements are one of the features of the present invention.
FIG. 2(b) shows a stopper B connected to the hinge (11) from the protrusion B (58) when the hinge (11) is hinged with the hinge screw set (111) and the lever (32) is rotated to the left. (62) is in contact with the hinge (11), the remaining part (42) of the rotating part (30) is rotating to the left, and a groove for an elastic body is provided in the lower end side of the neck main body (66). (84) is clearly exposed. In FIG. 3, the rotating part (30) of the bottle cap opening/closing device and the rotating recess (64) on the lower end side of the neck main body (66) face each other in a semicircular arc shape, so that, for example, a coiled spring can be moved between the members. The rotating part (30) and the neck main body (66) can be slid together without being hindered by the elastic body A (120).

Next, FIG. 4 will be explained.
FIG. 4 is a right rear perspective view of the cap (3), the rotating part (30), and the neck main body (66). You can imitate some kind of design on (30) and rearrange it depending on your mood, or you can make the top of the cap into a character shape instead of just a circular shape, which makes it possible to replace it in the same way and increase originality. becomes.

Next, FIGS. 5 to 8 will be explained.
FIG. 5 shows the neck main body (66), and (a) is a front view. Looking at (b), (C), and (D), it can be seen that a rear protrusion (76) is provided below the hinge connecting portion (72) above the rear surface of the neck main body (66). A torsion spring hole B (78) is provided on the upper surface of the rear protrusion (76). First, the lower end side of the torsion spring (100) shown in FIG. 7(b) is inserted into this hole, and then the lower end side of the torsion spring (100) shown in FIG. The upper end of the torsion spring (100) is fitted into the torsion spring hole A (9) provided on the lower surface side of the extending portion (7) of the cap (3) as shown in FIG. 7(d). ), where the end hole (17) of the end (15) and the hinge mounting hole (74) of the neck body (66) are aligned, insert the spring ring (102) of the torsion spring (100) into the hinge screw set (111). It is a very simple mechanism that is hinged. Further, at this time, the torsion spring (100) is designed to spring up toward the drinking spout (68) of the neck main body (66).
Next, regarding the rotating part (30) in FIG. 8, (a) is a front view, and (b) shows that about half of the rotating part (30) from the remaining part (42) is open (50). ), and a convex portion (52) on the inner periphery of the rotating portion is protruding from the middle of the remaining portion (42), and at the rear of the rotating portion (30) there is a convex portion (52) on the inner periphery of the rotating portion (30). As shown in FIG. It can be seen that it is formed.
(c) is a rear view of the rotating part (30), and the above-mentioned combination shown in FIG. The parts of the cap (3) and the neck main body (66) facing the hinge connection part (72) and the rear protrusion (76) are largely open, but as shown in FIG. 52) protrudes on a semicircular arc, so that it can be pivotally attached to the recess (70) of the neck main body (66) when it is press-fitted directly below, and at this time, the fastener A that is attached to the rotating part (30) (46) and fastener B (48), and fastener C (80) and fastener D (82) of the neck main body (66) are in parallel positions.

Next, FIGS. 9, 10, and 11 will be explained.
FIG. 9 shows a top view of the rotating part (30) pivotally attached to the neck main body (66) and a cross-sectional view of the hinge (11) of the cap (3). It can be seen that the hinge protrusion (13) protrudes from the part.
As described in the middle section of 0012, when the lever (32) is turned in either direction, the hinge (11) has a mechanism in which the torsion spring (100) springs up toward the spout (68) of the neck body (66). Therefore, when drinking, it is possible to hold the lever (32) while turning it in the rotational direction, but the emphasis was placed on eliminating this inconvenience by locking the hinge (11) with a stopper. Looking at (b) and (d) in Fig. 8, protrusion A (56) and protrusion B (58) are gently raised, and these protrusions rotate around the inner surface of the hinge (11) on either the left or right side. When the hinge (11) is rotated to a certain position, the stopper A (60) of the protrusion A (56) or the stopper B (62) of the protrusion B (58) presses down on the hinge (11) as shown in Fig. 9. It is a mechanism that catches and locks the part (13). This eliminates the need to hold down the lever (32) with your finger while performing a purpose such as swallowing the contents.
FIG. 10(a) is a plan view showing a state in which the rotating portion (30) is covered with the neck main body (66), FIG. 10(b) is a spring-like elastic body A(120), and FIG. It is a rubber string-like elastic body B (127), and (d) is the elastic body A (120) of (b) with the fastener B (48) of the rotating part (30) and the fastener of the neck main body (66). This shows that the elastic body A (120) is attached to D (82) and has its natural length.
11(a) shows a state in which the lever (32) has been turned to the right from the state shown in FIG. ) is attached to the fastener C (80) of the neck main body (66), and the lever (32) is turned to the left.
For example, at the time of sale, elastic body A (120) or elastic body B (127) is attached to clasp A (46) and clasp C (80) like this, and each person can attach the clasp on the opposite side according to their preference. It is also possible to replace elastic bodies with B (48) and fastener D (82). Also, as explained in the upper part of 0013, stopper A (60) or stopper B (62) is locked to the hinge convex part (13), and after the purpose is finished, the lever (32) is attached to the elastic body. When the lever (32) is turned further in the opposite direction, the diagonally installed stopper locking the hinge protrusion (13) pushes down the hinge protrusion (13) further and the lever (32) returns to the front position due to inertia, and at the same time The elastic body A (120) is designed to return to its natural length. At the same time, this mechanism also has the role of performing a locking function, and if it is a rubber string-like material such as the elastic body B (127), the cap (3) or the rotating part (30) Similarly, it is also possible to imitate character designs and change them to suit your mood.

Here, a wide mouth type (200) bottle cap opening/closing device will be described using FIGS. 12 to 14.
Even if the lever (32) is provided on the outer peripheral surface of the rotating part (30) as in the bottle cap opening/closing device of the narrow mouth type (190) in FIG. 1, the compression coil spring (140) and the torsion spring ( 100) and the elastic body A (120), we believe that watertightness can be achieved sufficiently, but Fig. 12 shows that in the case of large diameter items such as water bottles, the lever may get caught when taking them out of a bag etc. It is also necessary to assume that something may spill. Additionally, if you want something with a wide mouth type (200), the outer diameter of the bottle cap opening/closing device (1) needs to be made larger to match the large opening neck (175) like the water bottle container (170). Since it is expected that the elastic body A (120) will inevitably become thicker and longer in proportion to the weight of the member, the inner peripheral surface of the lever (32) and the remaining part (42) of the rotating part (30) By widening the gap between the elastic body grooves of the neck body (66), the fastener A (46) of the rotating part (30) and the fastener C (80) of the neck main body (66) or the rotating Prevent the lever (32) from coming into contact with the elastic body A (120) attached to either side of the fastener B (48) of the section (30) and the fastener D (82) of the neck main body (66). I can do it.
In addition, as shown in FIGS. 12(a), 13(a), and (b), the front part of the rotating part (30) is bulged out so as to shield the lever (32), and the small convex part A( 38), the rotating part (30) corresponding to the circumference of the leaf spring (145) interposed in the small convex part B (40) of the neck main body (66) is partially opened. , the rotating part (30) does not become a barrier when pushing the lever (32), and the purpose can be achieved.

The present invention provides a set of a wide-mouth automatic cap opening/closing device and a water bottle, or a narrow-mouth automatic cap opening/closing device that can be attached externally to a PET bottle container, so that the patient can use both hands, especially when injured or sick, or when driving a car. In case the upper part of the cap cannot be opened or closed, the upper part of the cap can be opened and closed with a small amount of force, and the elastic body works especially when the lid is closed.The structure is also simple and can be disassembled, so for example By combining several shaped elastic bodies with characters, it can be customized to each person's taste, and it is easy to clean, so it can be kept clean. In combination with this, it satisfies a variety of needs, such as not only regular use but also stocking up in case of a disaster.
