Description

Portable milk powder can}

The present invention relates to a infant milk bottle, and more particularly to a portable milk bottle having a dose dispensing structure so that the milk powder in the milk bottle can be easily dispensed by a desired dose.

In general, the infant formula is made of a cylinder, and at home, the amount of powdered milk required by the infant is taken out of the formula from the formula and filled into the formula, and the formula is poured by pouring water into the formula.

In the home (indoor), there is always a space to put the milk bottle, and the milk bottle is fixed in a certain place and the milk powder is used whenever needed. However, it is inconvenient to carry a bulky milk bottle directly in a moving car or outdoors, so use a portable milk bottle containing only the capacity required in a large milk bottle.

In addition, since such a portable powdered milk bottle may need to be used in a moving vehicle such as a car, it is not appropriate to open the lid of the powdered milk bottle and to pour the powdered milk inside the spoon with a spoon. Therefore, a product that makes an outlet on one side of the milk powder container and safely discharges the milk powder through this outlet has been produced. In addition, a product having a quantitative dispensing distribution structure that can control the discharge amount of the powdered milk in order to discharge only the required capacity has been produced.

The portable milk container having the above-described quantitative dispensing distribution structure has a structure in which the internal structure is divided into several parts or a rotary discharge port is installed in the discharge part to discharge only a predetermined amount per unit revolution.

As described above, the rotary discharge port is formed as a bottleneck, and is installed in this part. Therefore, after the powdered milk is discharged in one rotation, the powdered milk should be filled in the empty space again. It often happens that the particles are not completely filled due to the bonding force between the particles.

Therefore, in order to discharge the required amount, it has to be discharged several times, but after discharging, it is inconvenient to shake the powdered milk container to fill the empty space, and when it is desired to install and use a device having a plurality of distribution structures inside the powdered milk container, Each dispensing port has the inconvenience of having to form each discharge port, and also has the inconvenience of repeating the disassembly and assembly every time the powdered milk is added.

Infants are unable to control the amount they eat, so you should eat the right amount according to the age and development of the infant.

In order to ingest an appropriate amount, the volume discharged from the portable powdered milk container is accurately counted, but the above-mentioned conventional portable powdered milk container is complicated in structure and difficult to reliably dispense an appropriate amount. Accordingly, the present invention provides a portable milk powder container for discharging the required capacity by operating in a simple and simple manner, and reliably discharging the required capacity in consideration of the characteristics of the powdered milk.

The present invention provides a portable powdered milk container, characterized in that the upper end of the powdered milk storage portion further includes a storage box formed to accommodate a small breastfeeding article.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. 1 is an exploded perspective view of a portable milk bottle of the present invention.

As shown in FIG. 1, the milk powder storage unit 12, the capacity adjusting unit 14, the upper partition 16, the lower partition 18, the capacity adjusting cover 20, and the connecting pin 22 are largely shown in FIG. 1. , Milk powder outlet 24, the upper cover 26, the lower cover 28 is made up.

Milk powder storage unit 12 is formed in a cylindrical shape to store the milk powder, the upper cover 26 is coupled to the top, the powdered milk outlet 24 is coupled to the bottom. Coupling method of the powdered milk storage unit 12 and the upper cover 26 forms a screw thread on the upper outer periphery of the powdered milk storage unit 12, and a tab corresponding to the screw thread is formed on the inner circumference of the upper cover 26 to form an upper cover ( 26) is coupled to the top of the milk powder storage unit 12 and the bolt / nut coupling method. A storage box 34 is formed on the upper end of the upper cover to accommodate small items required for feeding. In addition, the milk powder storage unit is provided with a capacity display scale, an adjustment gear, and a guide groove. The formation position of the control gear and the guide groove is designed based on the capacity display scale, and this portion will be described later.

The capacity adjusting unit 14 is installed in contact with the inner diameter of the powdered milk storage unit 12 at the lower portion of the powdered milk storage unit 12 so as to be removable and rotated to discharge the powdered milk by a predetermined capacity while rotating. A plurality of storage portions 14a having upper and lower portions are formed. Only the half of the cylindrical portion 14a is formed at regular intervals, and the remaining space is closed. In the center of the dose adjusting portion 14 is formed a rotary shaft hole 14b facing the central axis of the dose adjusting portion 14, and the connecting pin hole 14c is formed on the side toward the center of the dose adjusting portion 14 have.

The upper partition 16 and the lower partition 18 are installed in close contact with the upper and lower ends of the capacity adjusting part 14 to fix the position of the capacity adjusting part 14 and at the same time the inflow of powdered milk during rotation of the capacity adjusting part 14. Outflow is determined. That is, the upper partition 16 is a half-moon-shaped space is formed in a plate-shaped plate and the remaining space is a closed structure formed a plurality of fixing grooves (16a) on the outer periphery corresponding to the fixing grooves (16a) 12a is formed in the inner diameter of the milk powder storage unit 12 so that the fixing groove 16a is inserted into the protrusion 12a to be fixed. The fixing position of the upper partition 16 should take into account the height of the dose adjusting portion 14.

In addition, a rotation shaft 16b is formed at the center of the upper partition 16, and the rotation shaft 16b is slightly longer than the depth of the rotation shaft hole 14b formed in the capacity adjusting section 14 described below. Allow the bottom partition to engage.

Like the upper partition 16, the lower partition 18 also has a half-moon-shaped space on the plate-shaped plate, the remaining space is closed, and several protrusions 18a are formed on the outer circumference, and the milk powder storage part ( 12, a fixing groove 12b corresponding to the protrusion 18a is formed so that the lower partition 18 is fixed to the milk powder storage unit 12.

The dose adjusting cover 20 is coupled to the outer circumference of the milk powder storage unit 12 and rotates along the outer circumference of the milk powder storage unit 12 in conjunction with the dose adjusting unit 14 to rotate the dose adjusting unit 14. do. In order to link the dose adjusting cover 20 and the dose adjusting portion 14 to the powdered milk storage portion 12, a slot-shaped guide groove 32 is formed, and at one side of the dose adjusting cover 20, a connection hole 20a. And a connecting pin 22 penetrating the connecting hole 20a and the connecting pin hole 14c to connect the capacity adjusting cover 20 and the capacity adjusting part 14. In the above, the length of the guide groove 32 determines the amount of rotation of the dose adjustment cover 20, and the length of the guide groove 32 is approximately equal to the distance at which the dose adjustment portion 14 rotates 180 °. Therefore, one end of the guide groove 32 coincides with one side initial position of the dose adjusting unit 14 and the other end of the guide groove 32 coincides with the other end position of the other side of the dose adjusting unit 14.

In order to allow the capacity adjusting cover 20 to discharge the desired constant capacity of powdered milk while functionally rotating it at the outer circumference of the powdered milk storage unit 12, the capacity adjusting cover is freely rotated at the outer circumference of the powdered milk storage unit 12. It should be formed in a structure that can be adjusted appropriately. This structure, as shown in Figure 1, to form a plurality of control gear 30 at a predetermined interval on the outer periphery of the dose adjusting portion 14 to which the dose adjusting cover 20 is coupled. The spacing of the adjustment gear 30 is the same as that of the scale formed in the milk powder storage section, and the spacing of the storage section of the capacity control section. And the structure of the control gear 30 is formed by a pair of engaging jaw (30a, 30b) facing each other at a predetermined interval.

In addition, the capacity adjustment cover 20 is rotated on the outer periphery of the powdered milk storage part, and requires a larger inner diameter than the outer periphery of the powdered milk storage part 12 in consideration of the height of the protruding control gear 30. Therefore, the inner diameter of one end of the cylindrical capacity adjustment cover 20 is formed with a protrusion line 20b along the circumference. As described above, when the protrusion line 20b is formed at one end of the capacity adjusting cover 20 and coupled to the powdered milk storage unit 12, the protrusion line 20b is not formed. In order to remove the floating structure, the milk powder storage unit 12 to which the opposite ends of the protrusion lines 20b are coupled is provided with a protruding jaw 12c, which is compensated by the height of the protrusion line 20b, on the outer circumference of the milk powder storage unit 12. It is formed along.

An adjustment protrusion 20c is formed at the center of the inner diameter surface of the capacity adjustment cover 20 so that the adjustment protrusion 20c of the capacity adjustment cover 20 is rotated when the capacity adjustment cover 20 is rotated at the outer circumference of the milk powder storage unit 12. And the locking jaw of the control gear 30 is rotated while rubbing at a constant pressure. That is, when the capacity adjustment cover 20 is rotated while the adjustment projection 20c and the locking projection 30a of the adjustment gear are rubbed, the adjustment projection is caught between the locking projections and then rotates. Therefore, when the user rotates the dose adjustment cover 20 and the adjustment protrusion 20c is caught between the locking projections 30a, the user stops the rotation and discharges the desired dose.

Rotational performance is good when the frictional pressure between the control protrusion 20c and the control gear 30 is lower than a predetermined pressure, but it is difficult to effectively secure one end locking function of the control protrusion 20c, and when the frictional pressure is higher than the predetermined pressure, the locking property is good. It is inconvenient to use because of poor rotation Therefore, in order to secure the locking and rotation at the same time by cutting the predetermined length in the circumferential direction in the circumferential direction to the upper and lower capacity adjusting cover 20 of the portion formed with the adjustment projection (20c) adjustment projection (20c) Appropriate elasticity is given to the to ensure rotational and once locking properties at the same time.

Capacity adjustment cover 20 is rotated on the outer periphery of the milk powder storage unit 12, because the phenomenon occurs by the inertia, preventing the capacity adjustment cover 20 is raised on the top of the projection jaw (12c) To form the upward prevention jaw (12d) so that the capacity adjustment cover 20 is always rotated in the same position.

The powdered milk outlet 24 is coupled to the lower end of the powdered milk storage unit 12 to guide the powdered milk discharged from the capacity adjusting unit 14 to be discharged to a desired place, and is formed in a funnel form. That is, the powdered milk outlet 24 has a thread formed at one end of the inner circumference, and a tab corresponding to the threaded thread is formed at the lower inner diameter of the powdered milk storage part 12, so that the powdered milk outlet 24 is formed with a powdered milk storage part ( 12) is coupled to the bottom.

The lower cover 28 is to keep the powdered oil outlet 24 always clean by closing the outlet 24a of the powdered oil outlet 24, and the diameter of the outlet 24 of the powdered oil outlet 24 is equal to the diameter of the outlet 24. In accordance with this, a latch 28a protruding a predetermined length is formed. The locking holes 28a are cut at regular intervals along the circumference so that each cut portion has a constant elastic force. That is, when the upper cover 26 is pressed on the discharge port 24a, the upper cover 26 is coupled to the discharge port 24a in a one-touch manner by pressing force, and on the contrary, when the upper cover 26 is pulled out, the catch 28a ), The discharge port 24a is removed and the discharge port 24a is opened. If the pressing force acts too strongly on the discharge port 24a inserted into the locking hole 28a, it is difficult to engage and separate, and if it is too weak, the upper cover is easily separated and the function of the upper cover is not secured, so the locking hole 28a It is preferable to make an incision considering the elastic force of the.

Referring to the preferred assembly process of the portable milk shaker configured as described above are as follows.

First, the powdered milk storage unit 12 is upside down and the upper partition 16 is mounted. That is, since the protrusion 16a is formed at the outer circumference of the upper partition 16, and the milk powder storage part has a fixing groove 12a corresponding to the protrusion 16a, the upper partition 16 is the milk powder storage part ( 12, the upper partition 16 is fixed at the point where the protrusion 16a and the fixing groove 12a coincide with each other. An upper cover 26 for opening the powdered milk storage part is coupled to the upper end of the powdered milk storage part 12.

After the upper partition 16 is fixed, the capacity adjusting unit 14 is mounted thereon. That is, since the rotating shaft 16b is formed at the center of the upper partition 16, and the rotating shaft hole 14b corresponding to the rotating shaft 16b is formed at the center of the capacity adjusting part 14, the rotating shaft 16b is formed on the rotating shaft 16b. If the rotary shaft holes 14b are inserted in coincidence, the position of the dose adjusting portion 14 is fixed and the rotation is possible by the rotary shaft 16b.

After the dose adjusting unit 14 is fixed, the lower partition 18 is mounted thereon. That is, as in the upper partition 16, the projection 18a is formed on the outer circumference of the lower partition 18, and the lower partition 20 is formed with a fixing groove 12b corresponding to the projection 18a. 18) the lower partition 18 is fixed at the point where the projection 18a and the fixing groove 12b coincide with each other by turning into the milk powder storage unit 12 on the dose adjusting unit 14. Since the lower partition 18 is fixed with a phase difference of 180 ° from the upper partition 16, the space part of the upper partition 16 and the space part of the lower partition 18 are always positioned oppositely.

After the lower partition 18 is fixed, the powdered milk outlet 24 is fastened thereon. That is, since a screw thread is formed on the outer circumference of the powdered milk outlet 24, and a tab corresponding to the thread of the powdered milk outlet 24 is formed at the lower end of the powdered milk storage part 12, the powdered milk outlet 24 is powdered. The bottom of the storage unit 12 is coupled to the bolt / nut coupling method. The powdered milk outlet 24 is coupled to the lower partition 18 while being in close contact with the lower partition 18 to function so as not to flow down.

After the powdered milk outlet 24 is fixed, the capacity adjusting cover 14 is mounted on the outer circumference of the powdered milk storage unit 12. That is, the connecting hole 20a of the dose adjusting cover 14 and the connecting pin hole 14c formed on the side of the dose adjusting part 14 coincide with each other, and then the connecting pin 22 is inserted into the dose adjusting part 14 and the dose. The adjusting cover 20 is integrally interlocked along the guide groove 32. As described above, the milk powder storage unit 12 is formed with a guide groove 32 through which the connecting pin 22 can move, so that the capacity adjusting unit 14 connected by the connecting pin 22 when the capacity adjusting cover 20 is rotated. ) Rotates integrally. In addition, the capacity adjustment cover 20 at the position where the connecting pin 22 is inserted is formed with a connecting pin locking device 22a for fixing the inserted connecting pin 22 so as not to be separated, thereby connecting the connecting pin 22 to the connecting pin 22. It is fixed to the pin locking device (22a) so that the connecting pin 22 is not separated. The order of assembly of the capacity adjusting cover 14 and the powdered milk outlet 24 may be changed according to the user's convenience.

After the capacity adjusting cover 20 is coupled, the lower cover 28 is finally mounted to the discharge port 24a of the powdered milk outlet 24 in a one-touch manner.

When separating the portable milk bottle assembled as described above, take out the connecting pin 22, the bottom cover 28 coupled to the bottom from the capacity adjustment cover 20, the powdered milk outlet 24, the bottom partition 18 In this order, the capacity adjusting unit 14 and the upper partition 16 may be sequentially separated.

Referring to the operation and use of the portable milk bottle assembled as described above are as follows.

Open the top cover 26 and fill the milk powder in the milk powder storage unit 12. The powdered milk filled in the powdered milk storage unit 12 is filled in the receiving portion 14a of the capacity adjusting unit built in the lower portion thereof. There is an upper partition 16 at the upper portion of the capacity adjusting unit 14, and the upper partition 16 opens only half, and the rest is not opened, so the milk powder passes only to an open place, and to an unopened place. It is not passed. That is, the powdered milk is filled only in the receiving portion 14a positioned at the lower part of the open place, and the rest is not filled. However, since the opening of the upper partition 16 and the entire receiving portion 14a coincide with each other at the initial position of the capacity adjusting portion 14, the powdered milk is filled in all the storing portions 14a. Here, the initial position means a state in which the 0 mark of the scale marked on the milk powder storage unit 12 and the arrow marked on the capacity adjusting cover 20 coincide.

Grab the capacity adjustment cover 20 with one hand at the first position, hold the powdered milk storage unit 12 with the other hand, and then rotate the capacity control cover 20 or the capacity control unit 14 to stop the aeration control cover 20. Rotates along the guide groove (32). Since the powdered milk storage part 12 has five scales formed in units of 20 ml from 0 ml to 100 ml, the user rotates the capacity adjusting cover 20 to a desired position. For example, if the arrow of the capacity control cover 20 is matched to the scale of 20ml by rotating the capacity control cover, the capacity control unit 14 which rotates in conjunction with the capacity control cover 20 also has a distance of one storage unit 14a. Rotate by. That is, the accommodating part 14a of the capacity adjusting part 14 is formed with five accommodating parts 14a, and the distance from one accommodating part 14a to the other accommodating part 14a is a milk powder storage part ( Since it corresponds to one step of the scale formed in 12), the capacity adjusting unit 14 is moved by one receiving unit 14a. In the above, the length of the guide groove 32 serves to determine the amount of rotation of the dose adjustment cover 20, the length of the guide groove 32 is approximately equal to the length rotated 180 ° of the dose adjustment portion.

When the dose adjusting unit 14 rotates, the powdered milk in the storage unit 14a of the dose adjusting unit 14 passes through the space of the lower partition 18 and is discharged to the milk powder outlet 24. On the contrary, since the upper partition 16 is installed at a phase difference of 180 ° with the lower partition 18, the upper end of the accommodating part 14a where the powdered milk is discharged is closed by the upper partition 16 so that no further powdered milk is discharged. Do not. As described above, if the capacity adjusting cover 20 is continuously rotated, as shown in FIGS. 2A, 2B, 2C, and 2D, the storage unit 14a of the capacity adjusting unit 14 is opened step by step. Discharged through the open space of the partition 18, on the contrary, the upper partition 16 maintains a phase difference of 180 ° with the lower partition so that no further milk powder discharge occurs.

Adjusting gear 30 formed in the powdered milk storage unit 12 is matched with the scale portion marked step by step, respectively, while rotating the capacity adjusting cover 20, the locking of the adjustment projection 20c formed on the capacity adjusting cover 20 When the friction is caught by the jaw 30a, the rotation of the capacity adjusting cover 20 is stopped once in this portion, thereby obtaining the required precise capacity.

When the capacity adjustment cover 20 is rotated, a phenomenon occurs by upward inertia, and is prevented from being raised by an upward bump 12d formed at the outer circumference of the powdered milk storage unit 12.

After dispensing as much milk powder as necessary by rotating the dose adjusting cover 20, the dose adjusting cover 20 is returned to its original position to refill the milk powder which has been removed from the receiving portion 14a, and more milk powder may be needed. In this case, the rotation of the dose adjusting cover 20 and the original position may be repeated repeatedly.

According to the present invention as described above, the powdered milk can be put into the milk bottle without having to weigh the volume every time, the volume can be arbitrarily controlled to use only the required capacity, and the container is small and light so that it can be carried indoors as well as conveniently carried outdoors. It can be used, and the operation method is simple, anyone can use it easily, and it is easy to clean because only the connecting pin is pulled out, so it is easy to clean and does not need to be disassembled and assembled every time. In addition, as the greatest effect of the present invention, the amount of milk powder required for feeding can be accurately discharged to a desired place by the receiving unit formed in the capacity adjusting unit by the rotating action of the capacity adjusting unit.
