Description

Baby straw cup

Technical Field

The present invention relates to a baby straw cup that can be used by inserting a straw into a cup lid for sealing the cup to prevent a baby from spilling a beverage.

Background

In general, when an infant drinks a beverage contained in a cup of a general shape with an open mouth, there are many inconveniences in that the beverage is carelessly flowed to the outside to dirty the surrounding environment and to stick the beverage to clothes, etc., depending on the degree of physical development.

In order to solve such inconvenience, a baby straw cup in which a straw is inserted into a cup lid for sealing the cup is proposed (see patent document 1 below). Accordingly, the cup cover is formed with a straw insertion part including a cutting part, the straw insertion part blocking the inside and outside of the container when a straw is not inserted, and the straw insertion part allowing a beverage to be drunk through the straw when the straw is inserted.

The straw cup for babies having such a structure is portable, thereby providing convenience when a baby is out. However, when several beverages (e.g. water, milk, juice) need to be prepared, several different cups must be carried for each beverage, which is cumbersome and takes up a large volume.

Fig. 1 is a perspective view of an infant straw cup according to an embodiment of the present invention, and fig. 2 is a perspective view illustrating a state in which a lid of the infant straw cup shown in fig. 1 is detached. Fig. 3 is a vertical sectional view of the cup body shown in fig. 1.

The infant straw cup according to the present embodiment includes a cup body 10, a partition plate 20, a cup cover 30, and a straw insertion valve 40.

The cup body 10 includes an inner space for containing a beverage, and has a shape that one side is blocked and the other side is open. In the case of the present embodiment, it is exemplified that the cup body 10 has a cross section of a circular shape, but the cup body 10 may have a cross section of a polygonal shape (e.g., a quadrangular shape).

The partition plate 20 is formed in the cup body 10 so as to divide the internal space of the cup body 10 into a plurality of beverage

accommodating spaces

11 and 12. According to the present embodiment, the partition plate 20 has a flat plate shape so as to form two

beverage containing spaces

11, 12, and the first containing space 11 and the second containing space 12 having a symmetrical shape are formed on both sides thereof with the partition plate 20 interposed therebetween.

Unlike the present embodiment, the partition plate 20 may be provided to form three or more beverage receiving spaces. For example, the three beverage receiving spaces may be provided to be evenly divided at an angle of 120 degrees.

The cap 30 is provided on the cup body 10 in such a manner as to cover the inlets of the

beverage receiving spaces

11, 12. The cap 30 is detachably provided at the inlet of the cup body 10 to open and close the

beverage receiving spaces

11, 12. In the case of the present embodiment, a configuration in which a plurality of locking members 80 are provided on the side surface of the lid 30 is exemplified for this purpose. The manner of fastening the cap 30 to the cup body 10 may be realized in various forms other than the constitution exemplified in the present embodiment.

The straw insertion valves 40 are respectively provided at positions corresponding to the respective

beverage receiving spaces

11, 12 of the cap 30. In the case of the present embodiment, two straw insertion valves 40 are disposed at the upper sides of the first and

second accommodation spaces

11 and 12, respectively. The straw insertion valve 40 is formed of an elastic material (e.g., silicone, rubber, etc.) and is provided so as to maintain a closed state at ordinary times and to switch to an open state when the straw 1 (see fig. 6) is inserted. When the straw 1 is removed from the straw insertion valve 40, the straw insertion valve 40 is again switched to the closed state by the elastic restoring force to prevent the beverage in the

beverage containing spaces

11, 12 from being exposed to the outside.

The cap 30 may be further provided with a spin cap 50 covering the straw insertion valve 40, the spin cap 50 being configured to open and close the straw insertion valve 40 by a spin operation. Fig. 1 shows a state in which the rotary cap 50 is closed, and fig. 2 shows a state in which the rotary cap 50 is opened, and leakage of the beverage from the straw insertion valve 40 can be doubly prevented by rotating the rotary cap 50.

The spin cap 50 may have a configuration including a cap body 51 connected to the cap 30 by a hinge and an insertion portion 52 formed to protrude from the cap body 51. The insertion part 52 may be inserted into the inlet of the straw insertion valve 40 in an insertion connection manner, and may prevent the beverage exposed from the straw insertion valve 40 from being exposed to the outside.

A handle member 70 including a handle 72 may be provided at the cup body 10 so that the infant can take the beverage by holding the handle 72 with the hand.

A guide for guiding the joining position when the cap 30 is joined may be provided between the handle member 70 (or the cup body) and the cap 30, and in the case of the present embodiment, as the above-described guide, it is exemplified that the circular portion 35 protrudingly formed at the cap 30 and the concave portion 75 concavely formed at the handle member 70 are arranged in a convex and concave shape with each other. The convex and concave shapes may be inverted from each other, and the shape of the guide portion may also be modified into various shapes other than the convex and concave structures.

The operational state of the above-described infant straw cup will be described. The

beverage receiving spaces

11, 12 of the cup body 10 may contain different kinds of beverages. For example, water may be contained in the first receiving space 11, and milk may be contained in the second receiving space 12. At this time, the straw insertion valve 40 corresponding to each receiving

space

11, 12 is in a closed state to prevent the beverage received in each receiving

space

11, 12 from being exposed to the outside.

In the case where the infant wants to take water, when the rotary cap 50 at a position corresponding to the first accommodation space 11 is opened and the straw 1 is inserted into the straw insertion valve 40 at the corresponding position, the straw insertion valve 40 is switched to the open state, so that the taking of water can be achieved. After the water intake is finished, when the straw 1 is pulled out from the straw insertion valve 40, the straw insertion valve 40 is switched to the closed state again, and when the rotary cap 50 is rotated to be closed, the water outflow is doubly blocked.

On the other hand, when the infant wants to ingest milk, the rotary cap 50 at a position corresponding to the second receiving space 12 is opened and the straw 1 is inserted into the straw insertion valve 40 at the corresponding position to accomplish the ingesting of milk. The explanation about the closing operation is replaced with the foregoing description about the first accommodation space 11 side.

Fig. 4 is a rear perspective view of the lid shown in fig. 2.

Referring to fig. 4, a gasket 60 for preventing leakage of beverage may be provided at the cap 30. The gasket 60 is formed of an elastic material (e.g., silicone, etc.), seals a gap between the cap 30 and the cup body 10 to prevent beverage inside the cup body 10 from leaking to the outside, and seals a gap between the cap 30 and the partition plate 20 to block beverage of the

respective receiving spaces

11, 12 from flowing into different spaces.

Fig. 4 shows a state where the gasket 60 is separated from the cap, and the gasket 60 may be detachably inserted into a gasket insertion groove 16 formed in the rear surface of the cap 30.

The gasket 60 may include an outer frame portion 61 (or an outer collar) having a shape corresponding to an opening portion (inlet portion) of the cup body 10, and a partition portion 62 having a shape corresponding to the partition plate 20 and formed inside the outer frame portion 61. The outer frame 61 serves to seal a gap between the lid 30 and the cup body 10 by contacting an end of the cup body 10, and the partition 62 serves to seal a gap between the lid 30 and the partition plate 20 by contacting an end of the partition plate 20.

The washer 60 may be formed with a knob 63 for detachment, and in the case of the present embodiment, a structure in which a pair of knobs 63 for detachment protrude inward from the outer frame portion 61 is exemplified. The user can easily detach the gasket 60 by holding the knob 63 for detachment with a hand.

The locking member 80 may be foldably connected to the cap 30 and may be provided in plurality along the outer face of the cap 30. A locking hook 85 is formed on the bottom surface of the locking member 80, and the locking hook 85 is hooked on a locking protrusion 15 formed to protrude from the outer circumference of the cup main body 10. The locking member 80 is fixed and released according to the locking and unlocking operations of the locking hook 85.

Fig. 5 is a perspective view of the pipette insertion valve shown in fig. 2, and fig. 6 is a sectional view illustrating an operation state of the pipette insertion valve shown in fig. 5.

Referring to fig. 5, the straw insertion valve 40 includes a valve body portion 41, a diaphragm 44, and a cutting portion 45.

The valve body 41 may have a structure including

hollow passages

49a and 49b through which the straw 1 is inserted, and including an upper body 42 and a lower body 43. The

hollow passages

49a, 49b may include an upper hollow passage 49a formed in the upper body 42 and a lower hollow passage 49b formed in the lower body 43.

The upper body 42 is fixed to the fixing hole 39 of the cap 30, and the lower body 43 is formed at a lower portion of the upper body 42 so as to contact and support the outer circumferential surface of the straw 1 when the straw 1 is inserted.

The inner side surface of the lower body 43 is formed such that the cross-sectional area of the lower hollow path 49b becomes narrower toward the lower side, and thus the straw 1 having various thicknesses can be applied. A vertical slit groove 48 extending from the lower end to a predetermined height may be formed at the lower body 43 such that the sidewall of the lower body 43 is laterally opened when the straw 1 passes through the lower body 43. The inner side surface of the lower body 43 may have a shape of a curved surface protruding inward.

An upper flange 46 and a lower flange 47 are formed on the outer peripheral surface of the valve main body 41, and the upper flange 46 and the lower flange 47 are hung on the upper and lower portions around the fixing hole 39 of the lid 30. This prevents the valve body 41 from being detached from the cap 30 in the vertical direction.

The diaphragm 44 is formed inside the valve main body 41 so as to block the

hollow passages

49a and 49b, and may be formed between the upper body 42 and the lower body 43 as shown in the present embodiment.

The cut portion 45 is formed by cutting the diaphragm 44 so that the diaphragm is deformed in accordance with the insertion of the pipette 1 to open the

hollow paths

49a and 49 b. The cut portion 45 may be formed such that a plurality of cut grooves intersect at the center of the diaphragm 44.

Next, the operation state of the straw insertion valve 40 will be described. As shown in fig. 6 (a), when the pipette 1 is not inserted, the diaphragm 44 blocks the hollow path 49 and is in a closed state.

If the pipette 1 is inserted as shown in part (b) of fig. 6, the diaphragm 44 is folded downward so that the pipette 1 passes through the diaphragm 44, and the pipette 1 moves downward while pressing the inner side surface of the lower body 43. In this process, the side wall of the lower body 43 is slightly opened to the side, so that the lower body 43 and the straw 1 are closely attached to each other due to the elastic restoring force.

When the pipette 1 is pulled out in the inserted state of the pipette 1, the side wall of the inwardly convex curved surface shape of the lower body 43 is kept not to rise upward to keep the contact force with the pipette 1 to some extent or more, and therefore, the pipette 1 is not easily detached upward. In other words, the straw 1 can be easily inserted, but not easily removed.

As shown in fig. 7, the handle member 70 may be detachably provided to the cup main body 10.

The handle member 70 may include a detachable ring 71 into which the outer circumference of the cup body 10 is inserted and fixed, and a handle 72 provided at the detachable ring 71.

The detachable ring 71 may be connected to the cup body 10 in an insertion connection manner, and a guide portion may be provided between the detachable ring 71 and the cup body 10, the guide portion guiding the connection therebetween. In the case of the present embodiment, the guide protrusion 18 and the guide groove 78 are listed as an example of the guide portion, the guide protrusion 18 is protrudingly formed at the outer circumference of the cup main body 10, and the guide groove is formed at the inner circumference of the detachable ring 71 for insertion of the guide protrusion 18. It is to be understood that the configuration of the guide portion may be modified in various other forms.

A handle 72 may be formed extending from the outer periphery of the detachable ring 71 so that a user can grasp the handle. In the case of the present embodiment, a structure in which two handles 72 are arranged in a symmetrical fashion on both sides of the detachable ring 71 is exemplified.

According to the above structure, the user can close the cup cover 30 and use the cup in the state that the handle member 70 is attached to the cup body 10, but can also close the cup body 10 with the cup cover 30 and use the cup in the state that the handle 72 is not attached to the cup body 70.

While the invention has been described with reference to specific embodiments thereof, it will be understood that various changes and modifications can be made by one skilled in the art within the spirit and scope of the principles of the invention as set forth in the following claims.
