Description

  The present invention relates to a container or container sealing structure capable of inserting and removing an object.

Conventionally, for containers that need to be sealed, such as medicine bottles, food storage containers, and electrical product containers, by screwing the cover against the container, the container is opened between the opening and the cover. Sealed with some rubber packing.
The battery housing part of the balance type bath provided next to the bathtub in the bathroom is also an example of a container that needs to be sealed, and FIG. 12A is a partial perspective view of the conventional balance type bath 1, FIG. (B) is the figure which opened the cover body 2 which can be attached or detached with respect to the battery accommodating part 4 provided in the bathtub 1.

  The bath 1 supplies a driving current to the display unit 3 and electrical components such as an igniter and a frame rod (not shown) with a battery 5 in order to avoid danger such as electric leakage. And this battery 5 is accommodated in the battery accommodating part 4 opened to the front so that replacement | exchange is easy, and this battery accommodating part 4 is sealed with the cover body 2 so that water may not penetrate | invade. In addition, a rubber packing 7 is disposed between the lid 2 and the opening of the battery housing 4 and sealed, and the bathtub 1 is provided with a collar 6 so that the shower water is supplied to the lid 2 or the battery. The housing 4 is not covered.

Specifically, the lid body 2 is fixed to the opening of the battery housing portion 4 with screws 8. At this time, the user compresses the rubber packing 7 while turning the screws 8 in order to increase the sealing degree. There is a need to. For this reason, the screw 8 is provided with knurls (notches) so as to be easily turned.
The balance-type bath 1 is often installed in a relatively small bathroom, and a soft body part such as a user's buttocks may come into contact with the knurled screw 8 to cause scratches. 6 also plays a role in preventing this body from contacting the screw 8.

Design Registration No. 8365553

By the way, regarding such a sealing structure of the container, it is possible to achieve a highly effective sealing only after the lid and screws are screwed so that the rubber packing is compressed and deformed. For this reason, in order to turn a cover and a screw, considerable force is required, and when it turns with halfway force, trouble will arise in a sealing degree. Further, when the lid is closed by applying force, the lid is often difficult to open when the lid is opened. For this reason, opening and closing the lid has been difficult for a powerless person such as an elderly person.
In consideration of reliable sealing of the container, it may be possible to adopt a sealing structure as shown in FIG. That is, the lid body 2A of FIG. 13 has a substantially cylindrical shape, and the O-ring seal 9 is accommodated so as to protrude slightly in a recess on the entire circumference of the peripheral side surface. And it is the structure which uses the handle 5 and inserts the cover body 2A in the opening part of the battery accommodating part 4, or pulls it out. However, in the structure of FIG. 13, when the lid 2 </ b> A is pulled out, a very large force is required due to the negative pressure in the internal space of the battery housing portion 4, and it is also necessary to use a large handle 5 for that purpose.

  The present invention is for solving such a problem, and provides a sealing structure for a container that can ensure the sealing of the container and can be easily opened and closed even by a weak person. The purpose is to do.

According to the first aspect of the present invention, the inner lid is in close contact with the opening of the container via a seal member, and the inner lid is movable in a direction approaching or separating from the inner lid. An outer lid connected to face the inner lid, and the outer lid is provided with an elastic member that exerts a biasing force in the separating direction between the inner lid and the outer lid. The outer lid or the container has a groove parallel to the rotational direction, and the other applies the inner lid to the opening, By rotating the outer lid in a state of approaching the inner lid side, the outer lid has a locking portion that is inserted and locked into the groove portion, and the locking portion is connected to the groove portion. The width of the groove is such that the corresponding locking portion can be rotated so that the outer lid can rotate without contacting the inner wall. Compared to rather large to, the container is a battery accommodating section to the wall of the bathtub and to have the opening of the substantially circular, which is stepped portion facing the outside formed on its inner wall, The outer lid is attached to the battery housing portion so as to contact the stepped portion, and the front view in the attached state has a diameter larger than the maximum diameter of the watering portion of the shower device. This is achieved by the sealing structure of the container having a circular shape .

According to the structure of Claim 1, since it has the inner cover which closely_contact | adheres to the opening part of a container via a sealing member, a container can be sealed with an inner cover.
The outer lid is movable in a direction approaching / separating from the inner lid, and has an outer lid coupled to face the inner lid. The outer lid is in a direction away from the inner lid. An elastic member that exerts an urging force is disposed. Therefore, if the outer lid is brought close to the inner lid while resisting the urging force of the elastic member, the inner lid can be pressed against the opening of the container by the urging force of the elastic member. The stopping degree can be increased.
If the outer lid is attached to the container in a state where the inner cover is pressed against the opening of the container by the elastic member, this high degree of sealing can be maintained.

In this regard, according to the configuration of the first aspect, the groove portion is provided in either one of the outer lid or the container, and the other portion is provided with the engaging portion that is engaged with the groove portion. The outer lid can be attached to the container by locking the locking portion and the groove portion.
And this latching | locking part is locked by a groove part by rotating in the state which applied the inner lid to the opening part and made the outer lid approach the inner lid side, but this outer lid approaches the inner lid side. In this state, the urging force of the elastic member is exhibited. Therefore, if the locking portion is locked to the groove portion, the inner lid can be pressed against the opening by the biasing force of the elastic member.

Further, the outer lid is rotatable relative to the inner lid, and the groove is parallel to the rotation direction of the outer lid. For this reason, no force is required to screw the lid into the container, that is, the outer lid is rotated without receiving resistance in the rotational direction of the seal member, and the groove and the locking portion are engaged. The outer lid can be easily attached to the container.
Further, when the outer lid is rotated to the opposite side to the case where the locking portion is inserted into the groove portion, the locking portion is detached from the groove portion, and the locked state between the locking portion and the groove portion is released. Then, the user can easily remove the outer lid and the inner lid connected to the outer lid using the biasing force of the elastic member.
In addition, the width of the groove is larger than the width of the corresponding locking portion. Therefore, the outer lid can be rotated so that frictional resistance does not occur between the locking portion and the groove portion, and the locking portion and the groove portion can be easily detached. Even if the width of the groove portion is larger than the width of the locking portion in this way, if the hand is released from the outer lid, the locking portion is pressed against the inner wall of the groove portion and locked by the biasing force of the elastic member. The outer lid can be fixed to the container without rattling.
At this time, the locking portion includes a protruding portion formed to protrude from the peripheral side surface of the outer lid and a protrusion slightly protruding from the protruding portion, and the groove portion is an inner wall of the opening of the container. Preferably, the inner wall of the opening is formed with an engaging portion that engages with the protrusion when the protruding portion is completely inserted into the groove.

According to the configuration of claim 1, the container is a battery container having an opening on the wall surface of the bath, the inner wall being provided with a stepped portion facing the outside, and the outer lid being a stepped portion. It is attached to the battery accommodating part so that it may contact | abut. For this reason, even if the water sprinkled from the shower invades vigorously from the gap between the peripheral edge of the outer lid and the wall surface of the bath tub, the water once hits the stepped portion. Therefore, it is possible to avoid the water sprayed from the shower from directly hitting the sealing member.
In addition, since the opening part of a battery accommodating part is substantially circular shape, and an outer cover is also substantially circular shape in a front view, even if it attaches an outer cover so that it may contact | abut to a step part, an outer cover can be rotated. .
Furthermore, the circular diameter of the outer lid is larger than the maximum diameter of the watering part of the shower device. For this reason, the water sprinkled from the shower does not enter directly from the gap at the entire periphery of the outer lid. That is, even if water enters into some gaps, water does not enter at least through all gaps. Therefore, it is possible to effectively avoid a situation in which shower water intrudes vigorously and a high water pressure is applied to the seal member.

According to a third aspect of the present invention, in the configuration of the first or second aspect , the wall surface is substantially vertical, and the groove portion is formed on the inner wall, and the drainage channel guides intruding water so that the infiltrated water does not collect. A falling path is provided between the outer lid and the inner lid for dropping infiltrated water onto the inner wall.
According to the configuration of the third aspect , the wall surface with the opening is substantially vertical, and further, a groove is formed on the inner wall of the opening, and a drainage channel is provided in the groove so that intrusion water does not accumulate. Yes. For this reason, the water that has entered the opening easily escapes to the outside.
Furthermore, since a falling path is provided between the outer lid and the inner lid to drop the infiltrated water onto the inner wall, the infiltrated water can be extracted to the outside through the opening inner wall.
In other words, these draining configurations are “a configuration in which high water pressure is not applied to the inside of the container”. Therefore, in combination with the structure for avoiding that the high water pressure that the “outer lid diameter is larger than the maximum system of the watering part of the shower device” according to claim 1 is applied to the seal member, the high water pressure is applied to the seal member. The situation can be reliably prevented.

A fourth aspect of the invention is characterized in that, in the configuration of any one of the first to third aspects, a desiccant is disposed on the inner lid. Therefore, moisture in the container can be removed with the desiccant.

  As described above, according to the present invention, it is possible to provide a sealing structure for a container that can ensure the sealing of the container and can be easily opened and closed even by a weak person.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings. In addition, the location which is attached | subjected with the same code | symbol in each drawing demonstrated below is a common structure.
In addition, since the embodiments described below are preferable specific examples of the present invention, various technically preferable limitations are given. However, the scope of the present invention particularly limits the present invention in the following description. As long as there is no description of the effect, it is not restricted to these aspects.

FIG. 1 is a schematic perspective view of a bath 10 provided with a container 50 and a lid 60 according to the first embodiment of the present invention, and FIG. 2 is a system diagram showing a main configuration of the bath 10 of FIG. .
The bath tub 10 is a balanced bath tub 10 installed in a bathroom, and its side surface SI is directly connected to a bathtub using a circulation fitting 19.
The bath tub 10 of this embodiment is a combined combustion apparatus to which a shower device 37 is connected. As shown in FIG. 2, the bath tub 10 is provided with a burner 40 for bathing and a burner 41 for hot water supply. The heat exchanger 42 for hot water and the heat exchanger 34 for hot water supply are heated to provide two functions of bathing and hot water supply.

  As shown in FIG. 1, such a bath tub 10 has a decorative panel that is entirely formed of a synthetic resin in a substantially rectangular shape, and an appliance plug knob 11, a hot water tap on the front side of the upper surface thereof. A switching lever 12, a hot water temperature adjusting knob 15, a shower pipe 13, and a hot water pipe 14 are attached. A capacity switching knob 16, a gas inlet 17 connected to the gas stopper, and a drain plug 18 are attached to the lower side of the front. A lid 60 that seals a housing (hereinafter referred to as “battery housing portion”) 50 that houses a battery for supplying power to each electrical component of the bath tub is attached to the upper front side. .

The instrument plug knob 11 is for igniting and appropriately selecting the supply of fuel gas to each pipe. Specifically, as shown in FIG. 2, the appliance plug device 20 is connected to the appliance plug device 20, and the appliance plug device 20 includes an electromagnetic valve 23 made of a metal that is adsorbed by magnetic force. The electromagnetic valve 23 opens and closes the boundary between the gas inlet 17 and the outlet using a spring. And the microswitch 22 as a detection means which detects the motion of the instrument plug apparatus 20 is arrange | positioned, and this microswitch 22 is connected to the control part 30. FIG.
Thus, when the user pushes the instrument plug knob 11 and lowers the electromagnetic valve 23, the boundary is opened, and the fuel gas introduced from the gas inlet 17 is supplied to the pilot burner 25 from the gas outlet. Then, the control unit 30 gives an instruction to the ignition device (igniter) 28 based on the operation of the micro switch 22, and the fuel gas is ignited by the electrode (ignition plug) 27, whereby the pilot burner 25 burns. The fire starts.
The appliance plug knob 11 also serves as a knob for selecting either a reheating function or a hot water supply function. The appliance plug device 20 supplies fuel gas to a hot water supply gas pipe 29 by means of a valve body 21 in the case. Alternatively, it is possible to select which of the bath gas pipes 26 is sent.

The hot water temperature adjustment knob 15 is for adjusting the temperature of hot water during hot water supply. As shown in FIG. 2, the hot water temperature adjustment knob 15 is connected to the diaphragm case 32 and flows through the pipe 39 passing through the hot water heat exchanger 34. And the amount of flowing water of the pipe line 38 which is a bypass pipe of the heat exchanger 34 for hot water supply is adjusted.
The diaphragm case 32 is divided into a high-pressure side and a low-pressure side by a diaphragm 33. When the hot water tap is opened, the pressure of the low-pressure side drops from the high-pressure side by the amount of pressure loss in the hot water supply heat exchanger 34. Thereby, when the hot water tap is opened and water is passed through the water supply pipe 35, the diaphragm 33 moves based on the pressure difference. In response to this movement, the valve body of the water pressure automatic gas valve 36 moves against the urging force of the built-in spring, and sends the fuel gas to the gas pipe 29 so that the fuel gas flows. A drain plug 18 is provided at the lower end of the diaphragm case 32.

The hot-water tap switching lever 12 is used to select the supply of hot water to either the shower pipe 13 or the hot water pipe 14 using the hot water supply function, and two pipe lines branched via the diaphragm case 32 38 and 39 are provided downstream.
The capacity switching knob 16 is for changing the number of hot water supply burners 41 to be burned. That is, the hot water supply burner 41 is composed of a plurality of burners, and the fuel gas supplied to each burner is controlled by the gas governor 43.

  In addition, such a bath tub 10 is provided with various safety devices, such as an overheat prevention device (temperature fuse) 44 for when the temperature in the device rises abnormally, and the flame of the burner inside the device. When the temperature of the flame rod 45 when it disappears, the temperature of the heat exchanger 34 for hot water supply rises abnormally, the hot water overheat prevention device (high limit switch) 46 for when the temperature rises abnormally, the water pressure inside the hot water supply heat exchanger rises abnormally An overpressure prevention safety device (overpressure relief valve) 47 for the time is provided.

The machine tools (including the accompanying machine tools such as the above various safety devices) for performing the chasing and hot water supply functions of the bath 10 such as the ignition device 28 as described above are electrically connected to the control unit 30. The control unit 30 controls each mechanical device based on information on each electrical component.
And the control part 30 is electrically connected with the battery accommodated in the battery accommodating part 50, and a battery supplies electric power to each machinery instrument via the control part 30. FIG. In addition, the single battery of 1.5V is utilized for the battery of this embodiment.
Further, the control unit 30 is also electrically connected to a display unit 49 disposed on the upper surface of the flange 24 that protrudes forward in FIG. 1, and the display unit 49 includes information on battery life (such as a battery replacement mark). ) Is displayed. Thereby, the user opens the cover body 60 that seals the battery housing unit 50 based on the information on the display unit 49, and replaces the battery. In addition, the collar part 24 has a role which prevents the battery accommodating part 50 from having water as much as possible, and, for this reason, the battery accommodating part 50 is arrange | positioned directly under the collar part 24 on the upper side of the front. .

Next, the battery housing 50 and the lid 60 for sealing the battery housing 50 will be described in detail.
[Outline of battery compartment (container)]
FIG. 3 is a schematic perspective view in which the lid 60 is opened and the battery housing portion 50 is viewed obliquely from the front, and FIG. 4 is a side view of the lid 60.
The battery housing portion 50 is a housing body that can be opened and closed by the lid body 60. The battery housing portion 50 is formed of, for example, a synthetic resin, and houses a dry battery that can be exchanged up and down as shown in FIG.
That is, the battery accommodating part 50 has the opening part 53 opened to the vertical wall surface FR of the front of the bath, and the battery can be exchanged by opening the lid 60 and putting a hand through the opening part 53.
In the present invention, the opening is an idea in a relative relationship with the lid, and does not mean only a hole in the same plane as the wall surface. When the lid is closed, the lid 60 receives the battery. It includes a region entering the portion 50 and its periphery.

The opening 53 of FIG. 3 has a circular shape when viewed from the front, and a groove 57 serving as a locking means for attaching the lid 60 is formed in the inner wall 53a.
Moreover, about the inner wall 53a, in the position deepened by the thickness dimension (dimension slightly smaller than D1 except the protrusion dimension of the knob | pick part 61 of FIG. 4) at the time of attaching to the opening part 53, the opening part 53 of FIG. The entire inner wall has an annular frame portion projecting inward in the radial direction, or an inward flange portion (hereinafter referred to as “frame portion”) 53b. In the case of this embodiment, the opening 53 is bent vertically from the wall surface FR toward the battery installation region 50 a to form an inner wall 53 a, and the inner wall 53 a is perpendicular to the circular radial direction of the opening 53. And an annular frame 53b is formed.

A seal member 55 is provided on the surface facing the outside of the frame portion 53b. The seal member 55 is a member for increasing the degree of sealing when an inner lid 62 (described later) of the lid body 60 is in close contact, and is formed of, for example, single foam (rubber packing).
In the case of this embodiment, the seal member 55 has a ring shape, and is crushed so that water does not enter when pressed by the inner lid 62 by an urging force of an elastic member 80 shown in FIG. Specifically, as shown in FIG. 7, the frame portion 53 b has a groove formed on the entire circumference and has an annular recess 87, and the seal member protrudes from the opening surface of the annular recess 87. 55 is inserted. The recessed portion 87 is formed into a tapered surface 89 by chamfering the opening edge (C surface cutting) so that the seal member 55 can be easily inserted.
The seal member 55 may be provided on the inner lid 60 side instead of the frame portion 53b. Further, the frame portion 53b of the present invention is not limited to the illustrated shape as long as it corresponds to the shape of the inner lid 60. For example, the frame portion 53b may protrude from the inner wall 53a so as to be inclined inward.

[Overview of the lid]
The lid 60 is formed of, for example, a synthetic resin except for an elastic member to be described later, and is embedded in the opening 53 so as not to protrude from the wall surface FR on the front surface of the bath tub except for a knob 61 for making the lid easy to attach and detach. It is supposed to be. The lid 60 has an inner lid 62 and an outer lid 64 that face each other. Hereinafter, the inner lid 62 and the outer lid 64 will be described with reference to FIGS.
5A is a rear view of the outer lid 64 (the surface on the inner lid side), FIG. 5B is a cross-sectional view taken along the line BB in FIG. 5A, and FIG. 5C is a diagram in FIG. It is an E direction arrow directional view. 6A is a front view of the inner lid 62 (surface on the outer lid side), and FIG. 6B is a cross-sectional view taken along the line CC in FIG. 6A. FIG. 7 is an explanatory diagram for attaching the lid 60 to the battery housing portion 50, and has a schematic cross section corresponding to the position of line AA in FIG. 8 is a view after the lid 60 is attached to the battery housing 50, and is a schematic cross-sectional view taken along the line AA of FIG. An enlarged view around 82). The groove portion 57 and the locking portion 82 are not shown in cross section along the line AA in FIG. 1, but for convenience of understanding, the groove portion 57 and the locking portion 82 are shown in cross section in FIGS. . FIG. 9 is an enlarged view of the FF portion of FIG.

[Configuration of inner lid]
The inner lid 62 is a lid for actually sealing the battery housing portion 50, and is in close contact with the opening portion 53 via the seal member 55.
As shown in FIGS. 6 and 3, the inner lid 62 of the present embodiment has a circular shape when viewed from the front and back according to the shape of the opening 53, and is slightly smaller than the diameter of the opening 53. In the state which has the small diameter L1 and the battery accommodating part 50 was sealed, the peripheral part contacts the seal member 55 provided in the frame part 53b.
Specifically, a recess 66 is formed on the entire periphery of the rear surface 62a of the inner lid 62 (surface on the battery installation area 50a side), and the recess 66 has a ring shape in the rear view. The convex part 69 is formed in the inside over the perimeter (the convex part 69 becomes a ring shape which has thickness as a whole). Then, as shown in FIGS. 8 and 9, the annular seal member 55 is pressed and deformed by the convex portion 69 with the lid 60 attached. Here, the convex portion 69 has a width W3 smaller than the width W4 of the seal member 55, and presses only a part of the seal member 55 (the central portion in the width W4 direction in this embodiment). For this reason, even if the battery housing part is sealed with the inner lid 62 and the inner side becomes negative pressure, when removing the lid 50, the negative pressure state can be easily released and the lid 50 can be easily removed. Become. In addition, the taper surface 89 for easily inserting the seal member 55 into the concave portion 87 at the time of manufacture also serves as a relief portion of the seal member 55 that is pressed by the convex portion 69 and swells in the width direction.
Also, as shown in FIG. 9, the depth D2 of the recess 66 and the protruding dimension of the projection 69 are the same, and when the inner lid 62 and the frame-shaped portion 53b are brought into contact with each other, the seal member 55 A portion 55 a (see FIG. 7) protruding from 87 enters the recess 66.

[Configuration of outer lid]
As shown in FIGS. 5 and 1, the outer lid 64 has a substantially circular shape in a front view and a rear view when attached to the battery housing portion 50.
The peripheral end 77 of the outer lid 64 is plate-shaped. On the other hand, as shown in FIGS. 7, 8, and 3, a stepped portion 59 that faces the outside is formed on the inner wall 53 a of the opening 53 of the battery housing portion 50. As shown in FIG. 8, the outer lid 54 is embedded in the opening 53 except for the knob 61 in a state where the back surface side (inner lid side) of the peripheral end portion 77 is in contact with the stepped portion 59. It has become. Thereby, even if the water of the shower apparatus 37 is sprayed vigorously, the water hits the stepped portion 59 and prevents further water pressure from being applied to the back.
The step portion 59 is formed so that the entire circumference of the inner wall 53a protrudes inward as in the case of the annular frame portion 53b, but the protrusion width is smaller than that of the frame portion 53b, and the inner lid rear surface 62a. This does not hinder the pressing of the seal member 55 on the seal member 55. That is, the outer lid 64 has a circular shape with a larger radius than the inner lid 62 by the peripheral end 77.

  The outer lid 64 has a knob 61 on the front surface (external side). The knob 61 does not extract the lid 60 from the battery housing 50, but mainly has a role of rotating the outer lid 64. In the case of this embodiment, as shown in FIGS. In a state where the lid 60 is attached to the battery housing part 50, the battery body 50 protrudes in a mountain shape in the vertical direction, and has a recess 61a on the protruding side surface. In addition, it is preferable that the knob | pick part 61 does not protrude from the wall surface FR as much as possible so that a naked user may contact and it is hard to collide.

[Configuration of inner and outer lids and their connection structure, etc.]
Such an inner lid 62 and an outer lid 64 are connected so as to be movable toward and away from each other, and are relatively rotatable with respect to a rotational direction intersecting with the approaching and separating direction. It is said that.
First, as shown in FIGS. 6 and 7, the inner lid 62 extends on the peripheral edge of the front surface (outer lid side surface) 62b on the outer lid 64 side and has a predetermined radius r3 from the center OP1. And a plurality of protrusions 67 arranged intermittently along the line. At the tip of each of the plurality of protrusions 67, a hook-shaped part 67a (in the case of the present embodiment, a hook-like shape bent outward) is provided.
On the other hand, as shown in FIG. 5 and FIG. 7, the outer lid 64 extends on the peripheral edge of the back surface (inner lid side) 64a on the arc and has a predetermined radius R3 from the center OP2. And a protrusion 68 formed along the line. Note that the protrusion 68 on the outer lid 64 side is provided over the entire circumference, and the whole is formed in a substantially cylindrical shape (ring shape in rear view). Further, a hook-shaped portion 68a (in the case of the present embodiment, a hook-like shape bent inward) is provided at the tip of the protrusion 68.
Then, as shown in FIG. 7, in a state where the inner lid 62 and the outer lid 64 are connected, the protrusion 67 and the hook-shaped portion 67a on the inner lid 62 side, and the protrusion 68 and the hook-shaped on the outer lid 64 side. The portions 68a are arranged corresponding to each other. That is, the protrusion 67 is disposed on the inner side of the protrusion 68 (radius R3> radius r3), and when the protrusion 67 is moved away from each other, the hook 67a and the hook 68a are locked. It has come to be.

In this way, the inner lid 62 and the outer lid 64 are movable and connected in a direction approaching and separating from each other. Further, the protrusion 67 and the protrusion 68 are formed on arcs having different radii from the center, and enable relative rotation (rotation in the RE direction in the figure). And since the projection part of at least any one of the inner cover 62 or the outer cover 64 is made into a cylindrical body as a whole, even if it rotates relatively, the connection is not removed.
In the present embodiment, the protrusions 67 and 68 are disposed at the peripheral edge, but the present invention is not limited to this as long as they are disposed corresponding to each other.

Further, as shown in FIGS. 5 to 8, the inner lid 62 and the outer lid 64 respectively have wall portions 70 and 75 extending in the respective directions, and the wall portions 70 and 75 are relative to each other. In this way, contact with each other when attempting to move in the radial direction prevents mutual movement in the radial direction.
Specifically, as shown in FIG. 6, the inner lid 62 is provided with a wall portion 70 on the inner side of the projection 67 of the front surface 62b and along an arc having a radius r1 from the center OP1. 70 is formed in a cylindrical shape as a whole. In FIG. 6A, the parallel diagonal lines attached to the wall portion 70 are not a cross section for convenience of understanding. A cylindrical body is cut out between the parallel oblique lines and is a falling path 89 as a drainage passage for intrusion water described later.
On the other hand, as shown in FIG. 5, the outer lid 64 is provided with a plurality of wall portions 75 along an arc having a radius R <b> 1 from the center OP <b> 2 on the inner side of the protrusion 68 of the back surface 64 a.
The wall portion 70 and the plurality of wall portions 75 are at least two or more when the outer lid 64 rotates relative to the inner lid 62 and moves in a direction different from the rotation direction RE. The wall portion 70 and the wall portion 75 are arranged so as to contact each other at a position facing each other.

Here, as shown in FIGS. 7 and 8, an elastic member 80 that exerts an urging force in a separating direction (X direction in the drawing) is disposed between the inner lid 62 and the outer lid 64.
The elastic member 80 according to the present embodiment is formed of a metal coil spring having a circular cross section, and thereby, when the outer lid 64 is rotated in the RE direction in FIG. it can.
Further, the elastic member 80 is disposed in the central region between the inner lid 62 and the outer lid 64 without being joined to both lids, and is provided with convex portions 71 provided toward the inner lid 62 and the outer lid 64, respectively. , 72 regulates excessive movement of the elastic member 80 in the radial direction.
As shown in FIG. 7, the elastic member 80 exerts an urging force in the separating direction (X direction) even when the inner lid 62 and the outer lid 64 are farthest apart from each other. The portion 67a and the hook-shaped portion 68a are locked.

The elastic member 80 is compressed in a direction in which the outer lid 64 and the inner lid 62 approach each other as shown in FIG. 8 in a state where the lid body 60 is attached to the battery housing portion 50. The seal member 55 is compressed by the convex portion 69 by being pressed against the portion 53b, whereby the sealing degree of the container can be increased.
The elastic member 80 exerts a biasing force in a direction in which the outer lid 64 and the inner lid 62 are separated from each other when the lid 60 is removed from the battery housing portion 50, so that the outer lid 64 is flipped outward. To work. For this reason, when the lid 60 is opened, the lid 60 can be easily taken out from the battery housing 50 even if the knob 61 is small.

  As shown in FIG. 8, there is a large space for water to enter between the outer lid 64 and the inner lid 62, while a plurality of protrusions are formed between the outer lid 64 and the inner lid 62 as described above. Portions 67 and 68, wall portions 70 and 75, and convex portions 71 and 72 are provided. For this reason, the inner lid 62 and / or the outer lid 64 are provided with a plurality of dropping paths 89 for allowing the ingress water to drop toward the inner wall 53a of the opening on the opposite surface. Specifically, as shown in FIG. 5 and FIG. 6, the falling path 89 includes notches (between parallel oblique lines) formed between the plurality of intermittently disposed protrusions 67 and between the cylindrical wall portions 70. ), Formed between a plurality of intermittently disposed convex portions 71 and 72. And in the state which attached the cover 60 to the battery accommodating part 50 like FIG. 8, between the outer cover 64 and the inner cover 62, it forms so that at least upper space and lower space may communicate, and outer cover 64 is a gap S between the peripheral edge 64 and the vertical plane FR, and the upper gap S1 and the lower S2 communicate with each other via the outer lid 64 and the inner lid 62.

[Mounting structure between lid and battery compartment (container), etc.]
Next, a structure for attaching the lid 60 to the battery housing 50 will be described.
As shown in FIGS. 3 to 8, a plurality of grooves 57 parallel to the rotation direction of the outer lid 64 (RE direction in FIG. 3) are provided in either the outer lid 64 or the battery housing portion 50. .
On the other hand, on the other of the outer lid 64 and the battery housing portion 50, the inner lid 62 is applied to the frame portion 53b of the opening 53, and the outer lid 64 is moved closer to the inner lid side and rotated in the RE direction. Thus, a plurality of locking portions 82 inserted into the groove portions 57 and locked are provided.
In the case of the figure, the locking portion 82 is a convex portion (hereinafter referred to as “protruding portion”) formed to protrude from the outer side surface (the peripheral side surface of the outer lid) of the substantially cylindrical projection 68 of the outer lid 64. Yes, as shown in FIG. The locking portion of the present invention has a convex shape as shown in the figure as long as the outer lid 64 is pushed into the opening 53 and then rotated in the RE direction so that it can be inserted and locked into the groove 57. It is not limited. For example, it is a configuration in which one of the pair of wall portions similarly constituting the U shape is inserted and locked with respect to the groove portion sandwiched between the pair of wall portions constituting the U shape. May be.

As shown in FIG. 8, the groove portion 57 has an inner wall 57a substantially perpendicular to the direction in which the inner lid 62 and the outer lid 64 approach and separate (the X direction in the figure). In the case of FIG. Are formed at four locations on the inner wall 53a (two locations are not shown). Specifically, a plurality of cutout portions 59a are formed in the stepped portion 59 that prevents water from striking the back, and the groove portion 57 is connected to the cutout portion 59a.
That is, the notch 59a is a guide groove that guides the protrusion 82 of the outer lid 64 of FIG. 4 to the groove 57, and is formed at four locations corresponding to the position of the protrusion 82 of the outer lid 64. It has a length L3 that is slightly larger than 82 length L2.
Thus, when the user fixes the outer lid 64 to the battery housing portion 50, the projection 82 is passed through the notch 59 a, and then the outer lid 64 is moved in the RE direction of FIG. 3 (that is, the inner lid and the outer lid). 3), the groove portion 57 is parallel to the rotation direction RE, so that the protruding portion 82 can be easily inserted into the groove portion 57.
At this time, the outer lid 64 does not rotate at least once, and is preferably not more than 1/4 rotation that can be easily twisted with one hand, and in this embodiment, after passing through the cut portion 59a. By rotating about 10 °, the entire side surface in the X direction of FIG. 8 (the approaching and separating direction of the inner lid and the outer lid) of the projecting portion 82 is locked to the groove portion 57.
On the contrary, when the outer lid 64 is removed, if the outer lid 64 is rotated counterclockwise in the RE direction so that the protruding portion 82 reaches the position of the notch 59a in FIG. Due to the urging force, the projecting portion 82 passes through the notch 59 a, and the embedded outer lid 64 is detached from the container so as to jump out from the opening 53.

  Furthermore, as shown in FIG. 8, the groove portion 57 has a width W1 that is larger than a width W2 of the protrusion 82 corresponding thereto. Therefore, the outer lid 64 can be easily rotated by preventing the protruding portion 82 from coming into contact with the inner wall of the groove portion 57 as indicated by the dotted line in FIG. Even if the width W1 of the groove portion 57 is larger than the width W2 of the protrusion portion 82, if the hand is released from the outer lid 64, the protrusion portion 82 becomes the inner wall 57a of the groove portion 57 as shown in FIG. It is pressed against and locked.

In the state where the outer lid 64 is attached to the opening 53 in this way, the exposed surface of the outer lid 64 is circular as shown in FIG. 1, and the circular diameter L4 (see FIG. 5) is As shown in FIG. 8, it is larger than the maximum diameter L5 of the watering part of the shower device (shower head) 37. In this regard, when the shower water enters the gap S between the peripheral end of the outer lid 64 and the vertical surface FR from the horizontal direction H, the water of the shower will invade vigorously. However, since the exposed surface of the outer lid 64 is larger, even if water enters the upper gap S1 in FIG. 8 from the horizontal direction H, the water enters the lower gap S2 in FIG. It is impossible to do. Therefore, it is possible to effectively prevent the shower water from invading vigorously and increasing the water pressure in the battery housing portion 50.
Moreover, as described above, even if water enters, the water falls on the inner wall 53a of the opening 53 in FIG. 3 through the dropping path 89 shown in FIG. And the groove part 57 formed in the inner wall 53a of FIG. 3 has the drainage channel 85 which guides intrusion water so that the water which permeated inside may not accumulate. Specifically, since the opening 53 is open to the vertical wall surface FR, the drainage channel 85 is provided in the lower groove portion 57 so that the step portion 59 is cut out from the groove portion 57 toward the wall surface FR. Is formed. Therefore, for example, even if water enters the upper gap S1 in FIG. 8, the intruding water is discharged from the lower gap S2 in FIG. 8, and a high water pressure is applied to the seal member 55, so that the water is installed in the battery installation area. Intrusion into 50a can be reliably prevented. The opening 53 and the inner wall 53a of FIG. 3 are circular when viewed from the front, and water on the upper half of the inner wall 53a falls, so that a drainage channel 85 is formed in the groove 57 arranged in the upper half. Absent.

  By the way, this drainage channel 85 has not only a function of draining the intrusion water but also a function of giving a click feeling for notifying the user that the protruding portion 82 has been reliably inserted into the groove portion 57. That is, as shown in FIG. 5 (c), the protrusion 82 on the lower side has a slight protrusion 82a protruding from the substantially quadrangular prism body, and has an L-shaped form in FIG. 5 (c). Yes. The protrusion 82 a is lightly caught by a notch-shaped drainage channel 85 connected to the groove 57 when the lower protrusion 82 is completely inserted into the groove 57.

The first embodiment of the present invention is configured as described above, and the outer lid 64 is attached to the battery housing portion 50 while being close to the inner lid 64 while resisting the biasing force of the elastic member 80. Thus, the inner lid 62 can be pressed against the opening 53 to increase the sealing degree.
The outer lid 64 is rotatable relative to the inner lid 62, and the groove 57 for locking the outer lid 64 and the battery housing portion 50 is parallel to the rotation direction RE of the outer lid 64. Therefore, when the outer lid 64 is rotated, the resistance in the rotation direction RE is only friction with the elastic member 80, and the outer lid 64 can be easily rotated to lock the groove portion 57 and the protruding portion 82.
Further, if the outer lid 64 is rotated to the opposite side to the case where the protruding portion 82 is inserted into the groove portion 57, the locked state between the protruding portion 82 and the groove portion 57 is released, and the user can apply the urging force of the elastic member 80. The lid 60 can be easily removed.
Note that when the lid 60 is fixed to the battery housing portion 50, the user needs to push the outer lid 64 toward the inner lid 62 against the elastic force of the seal member 55 and the urging force of the elastic member 80. However, this pushing operation is easier than, for example, a screwing operation against the elastic force of the seal member 55. Therefore, even a weak person can easily open and close the lid.

FIG. 10 is a schematic longitudinal sectional view of the housing body 100 and the lid body 110 according to the second embodiment of the present invention.
In FIG. 10, the battery housing portion 50 that is an example of the housing body of FIGS. 1 to 9 and the portions with the same reference numerals as the lid body 60 have the same configuration, and therefore, redundant description is omitted. The difference will be mainly described.
The container 100 according to the second embodiment is a food storage container for storing food, and has a configuration suitable for storing food.

That is, at least the opening of the container 100 is cylindrical, and a groove 57 that is parallel to the rotation direction of the outer lid 64 is formed in the outer side surface upper end portion 100a.
The outer lid 64 of the lid body 110 has a substantially circular shape when viewed from above, and is covered so as to cover the upper end portion 100a of the container 100, and is placed on the inner surface of the outer peripheral portion 112 that covers the upper end portion 100a. A protruding portion 82 is provided that protrudes inward in the radial direction. The protrusion 82 is engaged with the groove 57.
Thus, in 2nd Embodiment, it is set as the structure which covers the cover body 110 on the container 100, and latches the cover body 110 and the container 100 on the side surface exposed to the exterior of the container 100. Thus, the stored food such as jam is difficult to enter between the outer lid 64 and the inner lid 62.
Note that a guide 109 for guiding the protruding portion 82 to the groove portion 57 is formed at the opening end portion of the container 100 by being cut out so as to be connected to the groove portion 57.
The outer lid 64 is large enough to hold the outer peripheral portion 112 with one hand, and a knurled protrusion is provided on the outer peripheral portion 112 to facilitate the rotation of the lid.

The projections 113 and 114 provided on the inner lid 62 and the outer lid 64 have functions similar to those of the projections 67 and 68 in FIG. 7, but are generally cylindrical and the first embodiment. This is different in that no falling path 89 is formed. Further, the drainage channel 85 as in the first embodiment is not formed on the container 100 side.
In other words, in the second embodiment, the lid is covered so that water does not enter the container from above, for example, and it is configured on the assumption that at least the collected water does not enter the lid. On the other hand, in the first embodiment, as shown in FIG. 8, in view of the contact of the naked user, the surface of the lid 60 and the wall surface FR are flush with each other. A space S is formed between the wall surface FR and various measures are taken on the assumption that water enters from the space S.

In the case of the second embodiment, the seal member 108 is provided not on the container 100 side but on the inner lid 62. The sealing member 108 is formed by applying a liquid packing agent to the inner lid 62 and then drying and curing it. In this way, when the container 100 is washed, the seal member 55 is prevented from containing water.
In the case of the second embodiment, the elastic member 105 exerts an urging force in the direction in which the inner lid 62 and the outer lid 64 are separated from each other as in the first embodiment, but the inner lid 62 made of resin. Alternatively, a leaf spring shape integrally formed with one of the outer lids 64 is formed. The leaf spring-like elastic member 105 of the present embodiment is integrally formed with the inner lid 62 and is in contact (not connected) with the outer lid 64 only at a portion 107 having a predetermined area. Accordingly, when the outer lid 64 is rotated, the friction between the outer lid 64 and the elastic member 105 is reduced.

FIG. 11 is a schematic longitudinal sectional view of the container 120 and its lid 130 according to a modification of the second embodiment of the present invention.
In FIG. 11, the portions denoted by the same reference numerals as those of the container 100 and the lid body 110 of FIG.
The container 120 according to this modification is a so-called medicine bottle for storing medicine, and is configured to be suitable for storing medicine.

First, the container 120 is formed of glass having a predetermined thickness.
Further, the inner lid 62 has a desiccant 124 formed by filling silica gel in a bag having good air permeability on the inner space S1 side of the container 120, for example. Specifically, a plate-like member 132 that supports the desiccant 124 is formed on the inner lid 62 so that the desiccant 124 does not fall into the internal space S1, and the plate-like member 132 has a plurality of through holes 132a. Thus, the space for accommodating the desiccant 124 and the internal space S1 are communicated.

The elastic member 126 of this modification is configured by first and second springs 126a and 126b in the form of plate springs integrally molded with the resin outer lid 64, and the first spring 126a and the second spring. 126b is arranged symmetrically about the center OP3. Thereby, the urging force can be exerted in a direction in which the inner lid 62 and the outer lid 64 approach and separate in a balanced manner.
In the case of this modified example, the groove portion 57 is provided on the outer lid 64, and the protruding portion 82 is provided on the housing 120, and the guide 109 including a notch for guiding the protruding portion 82 to the groove portion 57 is provided. The outer lid 64 is formed.

In each of the embodiments described above, the battery container of the bath, the food storage container, and the medicine bottle have been described as examples of the container. However, the present invention is not limited to these as long as the container needs to be sealed. For example, it may be a base housing part of a personal computer or a battery housing part of a watch.
Moreover, when providing the slight protrusion 82a in the protrusion part 82, it is preferable to provide also in the protrusion part 82 which opposes, and it is preferable that there exist at least 1 pair (this application is 1 pair).
The notch-shaped drainage channel 85 has both the function of the drainage channel and the engagement function in which the slight protrusion 82a is lightly caught. However, the slight protrusion 82a is provided at the center of the projecting portion 82, for example. A dedicated engaging portion where the protrusion 82a is lightly caught on the inner wall 53a may be provided.
Further, when the slight protrusion 82a is provided, the width W2 of the protrusion 82 corresponding to the width W1 of the groove 57 described in the paragraph 0041 is set to a width W2 including the protrusion 82a (not contacting the inner wall of the groove 57). Thus, the protrusion 82 including the protrusion 82a can be inserted into the groove 57).
