Description

Technology Field

[0001] The present invention relates to a spring device configured to automatically open the lid of a water bottle for infants and children, and more specifically, to a spring device for opening the lid of a water bottle that has a simple structure and excellent assembly workability, and enables the automatic opening of the lid using the elastic force of silicone rubber with a spring function, without using metal springs that are harmful to the human body for hinge rotation due to the automatic opening of the lid, thereby reducing manufacturing costs. Background Technology

[0002] Breast milk or milk bottles for infants or children are designed so that the liquid outlet is protruding from the mouth of the bottle body in a sealed state, and the lid prevents the liquid (milk, barley tea) filled in the bottle from leaking out and prevents surface contamination except through artificial opening.

[0003] The water bottle is configured to be opened and closed by unlocking a lid body that is coupled to a water bottle body containing a beverage, a beverage outlet made of silicone material that is molded to protrude from the lid body, and a lid that is hinge-coupled to the lid body to receive the beverage outlet in a hermetic state and maintains a locked state by a locking means.

[0004] That is, it is known that a conventional water bottle for infants or children has a configuration in which a lid hinged to one side of a lid body is locked by a physical locking means on the other side, forcibly folding a silicone beverage outlet into a bent state to block the outlet, and when the locking state is released by a user pressing the locking means, the beverage outlet, which was pressed in a bent state, automatically rotates around the hinge on one side of the lid body with restoring elastic force, thereby exposing the beverage outlet in an upright state and opening.

[0005] The opening structure of this water bottle lid automatically opens the lid on one side of the hinge by the restoring force of the beverage outlet, which is forcibly folded into a bent state by rotation of the hinge, and selectively has a structure that allows drinking by holding it upside down through the beverage outlet, or by sitting upright and drinking if a straw is built inside the water bottle.

[0006] However, for such water bottles, the securement of the lid during carrying and the convenience of opening operation during use are important.

[0007] Thus, recently, various methods have been disclosed in which a beverage outlet having a spring function is forcibly folded and the lid is kept closed by a locking means, and then automatically opened by the restoring force of the beverage outlet that was forcibly folded by unlocking the lid that was locked by the locking means when drinking.

[0008] For example, Patent Document 1 proposes a ‘beverage bottle and lid having an opening button on the back of the lid’ in which the spout (straw) bent by the outer lid is automatically opened by the restoring elastic force of the spout by unlocking a push button configured in the hinge part while the spout is in a locked state.

[0009] In addition, Patent Document 2 proposes a ‘water bottle lid’ that automatically opens by releasing the locking state of a button assembly by means of the elastic force of a compression spring assembled at the hinge part, in which a cover (lid) that accommodates a silicone mouthpiece is released.

[0010] However, although Patent Document 1 has a structure that automatically opens using the elastic restoring force of a bent-deformed spout without the use of a metal spring, it has the disadvantage that the manufacturing cost increases because the structure of the lid for sealing and the bending deformation of the elastic spout (straw) are complex, and the structure of the push button for opening the lid is complex.

[0011] In addition, Patent Document 2 has the disadvantage that a metal compression spring is installed between the lid body and the button assembly to transmit elastic force in the direction in which the button assembly restrains the lid, that a large number of components of the button assembly are required to support this compression spring and that the molding structure is complex, and that it is difficult to separate and clean once assembled.

[0012] In particular, there is a disadvantage in that the reliability of the product is reduced because the molded part has many protrusions, and if these protrusions are damaged during long-term use, it becomes difficult to use.

[0013] In addition, the structure of the water bottle of Patent Document 1 necessarily requires the protruding molding of a spout with a straw function that can be forcibly folded into a bent state as a means to provide opening force of the lid.

[0014] Ultimately, the fact that the beverage outlet is not a protruding structure has the disadvantage of increasing manufacturing costs because a metal spring assembly structure is required in the hinge part for automatic opening of the lid. Prior art literature

[0015] Korean Published Patent No. 10-2013-0098941 (Published September 5, 2013) Korean Registered Patent No. 10-2444634 (Registered September 14, 2022) The problem to be solved

[0016] The objective of the present invention is to provide a spring device for opening a water bottle lid that ensures hygiene through the convenience of cleaning by eliminating the use of metal springs, simplifying parts, and enabling easy reassembly after disassembly and cleaning, by providing automatic opening through the elastic restoring force of the elastic member upon unlocking, while the beverage outlet and ventilation hole are locked in a sealed and compressed state by an elastic member assembled inside the lid. means of solving the problem

[0017] The spring device for opening the lid of a water bottle according to the present invention for solving the above problem is,

[0018] The present invention provides a spring device for opening a water bottle lid, wherein an elastic member assembled on the inner side of the lid, which rotates by means of a hinge on one side of a lid body assembled to the water bottle body and is locked by a locking means on the other side, stores a beverage outlet and a ventilation hole formed in the lid body in a compressed, airtight, and elastically deformed state, and automatically opens the lid by the restoring force as the deformed state of the elastic member is restored to its original shape upon release of the locking means.

[0019] In the present invention, the elastic member is characterized by being integrally molded such that a first elastic stopper that adheres to the upper part of the beverage outlet and a second elastic stopper that seals the ventilation hole are elastically connected to each other, and the first and second elastic stoppers are molded as stepped protrusions having an expanded stepped ring on the upper part and assembled by press fitting into an assembly hole formed through the lid.

[0020] In addition, the present invention is characterized in that the elastic member is assembled in an upright position in which shaft protrusions protruding on both sides are prevented from detaching by press fitting into an assembly shaft groove formed on the hinge side of the lid body in the shape of a plate, is elastically bent and stored by the hinge rotation of the lid, and automatically opens by the restoring elastic force when the lid is opened and rotated.

[0021] In addition, the present invention is characterized in that the elastic member is formed in the shape of a rod and is assembled with an extended stepped ring at the top to prevent detachment of the press fit in an assembly hole penetrating the hinge side of the lid, and is stored by shrinkage deformation as the tip contacts the upper surface of the lid body when the lid hinge rotates, and is automatically opened by the restoring elastic force of the elastic member when the lid rotates to open. Effects of the invention

[0022] According to the present invention, there is an advantage of reducing manufacturing costs by minimizing the components of a water bottle lid manufactured by injection molding.

[0023] In other words, the present invention provides button operation without the use of a metal spring, offering the advantages of convenient assembly with minimal parts, easy separation for cleaning, and simple reassembly, while ensuring convenience of use without damage during long-term use by enabling automatic opening of the lid using the restoring elastic force as the deformation state of the elastic member assembled to the lid or lid body is restored simultaneously with the application of the button of the locking means.

[0025] The present invention will be described in detail below with reference to the attached drawings.

[0026] (1st embodiment)

[0027] FIG. 1 is a perspective view of a lid body according to the present invention with the lid open, FIG. 2 is an exploded perspective view of a component according to the present invention, FIG. 3 is an exploded perspective view showing a partial cut of a key component according to the present invention, FIG. 4 is a cross-sectional exploded view according to the present invention, FIG. 5 is an assembled cross-sectional view with the lid closed according to the present invention, and FIG. 6 is an assembled cross-sectional view with the lid open according to the present invention.

[0028] Referring to these drawings, the present invention is largely composed of a lid body (110) screw-assembled to the opening of a water bottle body (100), a lid (200) connected to one side of the lid body by a hinge (250) assembly, and an elastic member (300) assembled to the lid to automatically open the lid (200) with elastic force while providing a sealing function.

[0029] The above lid body (110) has a protruding beverage outlet (120) with a straw function in the center and a ventilation hole (130) on one side.

[0030] Here, the beverage outlet (120) allows a user to drink a beverage, such as water or milk, filled in the container body (100), and the ventilation hole (130) allows air to flow into the interior of the container body (100) when the user inhales the beverage using the beverage outlet (120), thereby facilitating the inhalation of the beverage.

[0031] And the hinge (250) is formed by the assembly of a hinge shaft support (251) integrally molded on the lid (200) corresponding to a hinge shaft (151) molded on one side of the lid body (100).

[0032] Additionally, the lid body (110) includes a locking means (150) provided on the opposite side of the hinge (250) to maintain the lid (200) in a closed state.

[0033] This locking means (150) is configured such that a button (160) made of silicone material is assembled to a button fixing guide (170) assembled to a button fixing part (140) that is molded to protrude forward on the lid body (110), and the lock piece (210) of the lid (200) locked by the button fixing guide (170) is released and opened by the pressure of the button.

[0034] The above lock piece (210) is formed such that the lid (200) is integrally molded and a locking projection is formed at the tip of the lower part of the protruding gripping projection, extending vertically and being inserted through a hole penetrating the upper part of the button fixing part (140), and is locked in a state where the locking projection is engaged with the button fixing guide (170), and when the button fixing guide (170) is retracted by the user pressing the button (160), the locked state is released. Since this locking means is a known technology, it will be sufficiently understood without a detailed explanation.

[0035] The present invention is characterized by the fact that when the locking state of the lock piece (210) of the lid (200) is released by the horizontal movement (reverse movement) of the button fixing guide (410), the lid is automatically opened by upward rotation through the hinge (250) by the restoring elastic force of the elastic member (300) assembled on the upper part of the lid body (110) and the inside of the lid (200).

[0036] In other words, the core technology of the present invention is to assemble and configure the elastic member (300) so that the lid (200) is kept locked by the locking means (150) and then automatically opens upward by the hinge (250) when the locking means (150) is unlocked.

[0037] The elastic member (300) of the first embodiment of the present invention is,

[0038] A first elastic stopper (310) that adheres to the upper part of the beverage outlet (120) of the lid body (110) and a second elastic stopper (320) that seals the ventilation hole (130) are connected to each other by an elastic joint (330) and formed as a single unit.

[0039] At this time, the first and second elastic plugs (310, 320) are formed with stepped protrusions (311) (321) having an extended stepped ring on the upper side, and are assembled by press fitting into each assembly hole (220) (230) that is formed through the corresponding lid (200) so as to be assembled without detachment.

[0040] In other words, since the user can forcibly disassemble, clean, and reassemble the unit, it offers the advantage of hygiene even with long-term use.

[0041] The elastic member (300) assembled in this way is stored by elastic deformation inside the lid (200) at the same time as the lid (200) is locked by the locking means (150), as shown in FIG. 5.

[0042] That is, the first elastic stopper (310) and the second elastic stopper (320) are stored in a state where they are elastically deformed and compressed against the upper part of the beverage outlet (120) and the ventilation hole (130) of the lid body (110), and at the same time, the elastic rod (330) is stored in a state where it is bent upward like a bow due to force deformation.

[0043] In this state, as illustrated in FIG. 6, the elastic member (300), which was forcibly stored in an elastically deformed state by unlocking the locking means (150), is restored. That is, the compression state of the first elastic plug (310) is restored, and at the same time the elastic rod (330) extends downward and the compression state of the second elastic plug (320) is restored simultaneously, and with this restoring elastic force, the lid (200) is automatically opened upward around the hinge (250).

[0044] (2nd Example)

[0045] As shown in FIGS. 7 and 8, the second embodiment is composed of an elastic member (301) that protrudes upward by press assembly into an assembly shaft groove (111) formed on the hinge (250) side of the lid body (110) in the shape of a plate, which is the elastic member (300) of the first embodiment of the present invention.

[0046] As shown in FIG. 9, the elastic member (301) of this second embodiment is assembled in an upright position with the shaft projections (301a) protruding on both sides being forced into the assembly shaft groove (111) to prevent detachment, and as shown in FIG. 10, it protrudes in an upright position when the lid (200) is open, and as shown in FIG. 11, when the lid (200) is closed, the elastic member (301) is elastically bent in the rotational direction of the lid (200) and stored, and then when the lid (200) is opened again, the lid (200) can be automatically opened by the restoring elastic force.

[0047] This second embodiment of the present invention has the advantage of being able to provide automatic opening of the lid (200) as a simple structure.

[0048] (3rd Example)

[0049] As illustrated in FIGS. 12 to 14, the third embodiment of the present invention is configured such that the elastic member (302) is assembled in the shape of a rod with an assembly hole (212) penetrating the hinge (250) side of the lid (200) to prevent detachment of the forced fit with an extended step ring (302a) on the upper side, and the tip is received by contraction deformation as the lid (200) hinge rotates, and then automatically opened by the restoring elastic force of the elastic member (302) when the lid (200) rotates open.

[0050] This third embodiment of the present invention also has the advantage of being able to provide automatic opening of the lid (200) as a simple structure.

[0051] As such, while specific embodiments have been described in the detailed description of the present invention, it is understood that various modifications are possible within the scope of the invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be defined by the claims set forth below as well as equivalents thereof.
