In particular, the moving piece 14 that opens and closes the air inlet 13 is for introducing air into the water bottle. That is, when drinking water from a water bottle, pressurize the water bottle with your hand while holding the discharge part 11 in your mouth. Since the volume of the water bottle decreases as much as the volume of water you drink, it is difficult to pressurize the water bottle additionally and if there is little water left, It does not discharge well. Therefore, there is an advantage in that drinking can be done conveniently through the air inlet 13 and the moving piece 14 even when there is little water remaining in the water bottle.

However, the moving piece 14 is made of an elastic material composed of a conical head, a cylindrical body, and a flat-plate tail, and the opening and closing of the inlet 13 is performed by the internal pressure of the water bottle and the weight of the moving piece 14. However, a problem has been pointed out that sometimes it does not work properly because it is affected by the shape change of the moving piece 14.

The filter accommodating member 200, one side of which is connected to the fixing part 100, will be described. The filter accommodating member 200 includes an upper support portion 210 for fixing one end of the filter 300, a lower support portion 220 for fixing the other end of the filter 300, and the upper support portion 210 and the lower support portion ( 200) is configured to include a side support 230 connecting.

First, the upper support part 210 will be described. The side and upper surface are sealed so that one end of the filter member 300 can be fixed, while the inside is empty so that one end of the filter member 300 can be accommodated.

More specifically, a cylindrical first connecting member 211 having a predetermined length is provided on the outer side of the upper surface so as to be in close contact with the holder 130 while being inserted into the inner surface, and in the center of the upper surface, a first through hole ( 212) is formed. In addition, a third connection member 213 extending a predetermined length toward the center of the filter member 300 while being in communication with the first connection member 211 and the first through hole 212 is provided, which is a filter member ( 300), that is, to provide a movement path for water passing through the filter member 300, while supporting the filter member 300 more firmly.

As a result, the water passing through the filter member 300 sequentially passes through the third connection member 213, the first through hole 212, and the first connection member 211, and then moves to the discharge unit 110. It will be.

Here, the coupling method between the holder 130 and the first connecting member 211 is not particularly limited, but may be a male and female screw fastening method or may be fixed with an adhesive or the like.

The lower support part 220 has a hollow inside so that the other end of the filter member 300 can be accommodated while the side surface and the bottom surface are sealed. In addition, a second through hole 221 coupled to an air inlet member 400 to be described later is formed on the lower surface.

The side support 230 has a cylindrical shape with an empty inside to accommodate the filter member 300, and has a plurality of slits 231 so that water in the water bottle can flow into the filter member 300. One end of the side support 230 is closely fixed to the inner surface of the upper support 210 and the other end is closely fixed to the inner surface of the lower support 220 .

Here, the filter 330 preferably has a pleated shape in which predetermined portions are folded along the longitudinal direction, because the filter surface area per unit volume can be increased and the filter shape can be easily maintained. Of course, water introduced from the outside of the filter and passed through the filter may pass through the third connection member 213, the first through hole 212, and the first connection member 211 sequentially, and then move to the discharge unit 110. It is obvious that the filtered water movement passage is provided inside.

9 is an enlarged perspective view of a state in which the air inlet member is coupled to the lower support part of the portable water bottle cap shown in FIG. 5, FIG. 10 is a cross-sectional view of the lower support part and the air inlet member shown in FIG. 9, and FIG. 11 is shown in FIG. An exploded perspective view of a lower support and an air inlet member, and FIG. 12 is an enlarged perspective view of the inside of a lower body constituting the air inlet member.

The air introduction member 400 will be described in detail with reference to FIGS. 9 to 12 .

The air inlet member 400 installed on the other side of the filter accommodating member 200, specifically, in the second through hole 221 of the lower support 220 and guiding air into the water bottle B, is an upper body 410, It is composed of a lower body 420, a ball 430, a spring 440 and a packing member 450.

The upper body 410 connected to the second through hole 221 of the lower support 220 described above has a cylindrical shape with an empty inside and is composed of an upper surface and a side surface, and is inserted into the second through hole 221 outside the upper surface. The first extension part 411 of a cylindrical shape extends upward by a predetermined length so as to be able to do so.

Here, a portion of the first extension portion 411 has a cylindrical shape having the same length as the thickness of the lower support portion 220 (ie, the height of the cross section in the drawing) and the same outer diameter as the second through hole 221, and then It is preferable to have a conical shape in which the outer diameter decreases as it goes upward, so that it is easy to fasten to the second through hole 221 through a forced press-in method, and to prevent easy separation after fastening. Of course, a part or all of the end of the first extension part 411, that is, the columnar part, is inserted into the central part of the second sealing part 320, that is, the filtered water passage.

The lower body 420, which is fastened to each other by being in close contact with the inner surface of the upper body 410, is composed of a first body 421 and a second body 422.

First, the first body 421 is in close contact with the inner surface of the upper body 410 and has a hollow cylindrical shape, and has a plurality of ribs 421 (a) extending along the longitudinal direction of the inner surface. ) Is provided in a radial shape, which is to secure the space portion (S), which is the movement path of air.

That is, when the ball 430 is accommodated in the inner space of the lower body 420, the ball 430 moves up and down along the end of the rib 421 (a), and at this time, the ball 430 moves inside the upper body 410. Since it is spaced apart from the side surface by the width of the rib 421 (a), a space S through which air can move is secured.

The second body 422 is connected to one end of the first body 421 and may have a substantially disc shape.

At the center of the second body 422, a third through hole 422(a) for guiding air introduced from the outside into the water bottle is drilled.

In addition, it is preferable that a plurality of incisions 422 (b) cut to a predetermined depth in a trapezoidal shape are formed near the edge of the third through hole 422 (a), which ensures air inflow into the water bottle. To do so, it will be described later.

Meanwhile, the outer diameter of the second body 422 is preferably the same as the outer diameter of the upper body 410, which is to prevent a step from occurring on the outer surface after the lower body 420 is accommodated and fixed inside the upper body 410. am.

The circular ball 430 is arranged to move up and down along the inside of the lower body 420, more specifically along the end of the rib 421 (a) of the first body 421.

One side of the coil-shaped spring 440 supporting the ball 430 with a predetermined elastic force is located below the ball 430, and the other side is located on the upper surface of the second body 422, more preferably the aforementioned incision groove 422 ( b)) are located across them.

Reference numeral 450 is a packing member, which may be a circular O-ring for completely blocking water and air, but may be omitted if a sufficient airtight effect can be expected only with the ball 430.

When the water bottle cap having the above structure is mounted on the water bottle, when drinking water by pressing the water bottle by hand, the passage inside the first extension part 411 is formed by the external pressure applied to the water bottle and the elastic force of the spring 440. Since it is blocked by the 430, the water passes through the side support 230, the filter 330, the third connection member 213, the first connection member 211 and the discharge unit 110 of the filter receiving member 200. It is discharged to the outside while passing through.

After drinking water, the volume of the water bottle itself is reduced by that much, so the pressure inside the water bottle is relatively lower than the outside. , Since the air moves into the water bottle via the filtered water movement passage inside the filter 330, the first extension portion 411, the space portion S, and the third through hole 422 (a), the water bottle is in its original state. It will come back to volume.

This is a structure in which the coil spring 440 contracts due to the relatively low internal pressure of the water bottle and thereby allows the ball 430 blocking the inner passage of the first extension part 411 to be opened. However, if the pressure inside the water bottle is too low, the coils come into close contact, and since the circular ball 430 is located in the center of the coil, it may be difficult for the air to move to the third through hole 422(a). .

However, in the present invention, since a plurality of cutout grooves 422(b) are formed near the edge of the third through hole 422(a) of the second body 422 on which the coil spring 440 is seated, the coils are perfectly formed. Even in the case of close contact, it is possible for air to move to the third through hole 422 (a) through these incisions 422 (b).

As above, specific parts of the present invention have been described in detail, and to those skilled in the art, these specific descriptions are only preferred embodiments, and the scope of the present invention is not limited thereby, and the scope of the present invention It is obvious to those skilled in the art that various changes and modifications are possible within the scope and scope of the technical idea, and it goes without saying that these changes and modifications fall within the scope of the appended claims.
