Description

Infant container with easy-to-attach cap

[0001] The present invention relates to an infant container with an easy-to-attach cap member, and more particularly, to an infant container, particularly a baby bottle, which connects a flexible cap member, such as a baby bottle or baby food container, to a hard container-shaped body by a one-touch attachment / detachment method rather than a conventional screw attachment method, thereby making use convenient and enhancing airtightness by using a soft cap member.

[0002] Infant containers such as baby bottles, baby food containers, and drinking cups for straws are used by combining a flexible material cap, such as silicone, similar to a nursing nipple, with the container body. Due to the nature of the soft material, the cap cannot be directly combined with the container body.

[0003] Taking a baby bottle as an example, the structure is such that a nipple is fitted into a cap made of a hard material such as plastic, and the cap is connected to a container-shaped body.

[0004] That is, the user checks the joining position so that the screw threads formed on the outer surface of the spout of the container-shaped body and the Nana threads formed on the inner surface of the cap member are well interlocked and fastened, and then rotates the cap member in one direction based on the container-shaped body to fasten the container-shaped body and the cap member.

[0005] Due to the nature of the screw connection method, the contents of the container often leak out due to the cap not being completely closed or being filled crookedly.

[0006] Especially in the case of baby bottles, the cap must be completely locked with strong force to prevent the contents from leaking through the gap in the nipple connection part, but the screw connection method has the disadvantage that the cap often does not completely lock.

[0007] In addition, the cap member rotates as the screw threads of the cap member ride the screw threads of the container body. The entire process of riding the screw threads is the process of fastening the cap member to the container body. Since the user must fasten the cap member to the container body while paying attention to the entire process of the cap member riding the screw threads, it takes a long time.

[0008] Meanwhile, the container body of infant containers such as baby bottles is sometimes made of hard materials such as PPSU or PP, and sometimes of soft materials such as silicone.

[0009] In cases where the container body is made of soft material, a more convenient method of fastening the cap member is being designed by taking into account the characteristics of the soft material.

[0010] In cases where the container body is made of hard material, the screw connection method mentioned above is not convenient from the user's perspective, but is still being used without any alternatives being devised.

[0011] For reference, prior art technologies regarding the method of fastening the cap of a baby bottle, which can be considered a representative infant container, include Patent Publication No. 10-2022-0043262, Patent Registration No. 10-1894739, Utility Model Registration No. 20-046826, and Patent Registration No. 10-1328519.

[0012] Accordingly, the present invention has been devised to solve the above-mentioned problems.

[0013] The purpose of this invention is to provide a container for infants, especially a baby bottle, in which the material of the container-shaped body is made of a hard material such as PPSU or PP, and the fastening structure between the container-shaped body and the cap member is improved to increase the convenience of use.

[0014] In order to achieve the above purpose, the infant container according to the present invention,

[0015] Container-type body,

[0016] Including a cap member that is coupled to the periphery of the spout of the above container-shaped body,

[0017] The above container-shaped body includes a plurality of locking protrusions protruding from the circumference of the spout portion,

[0018] The above cap member is characterized by including a fitting part formed upward from the lower end of the inner surface, a locking part connected to an upward slope in one direction from the upper end of the fitting part, and a fixing part connected horizontally from one end of the locking part, and including a plurality of locking grooves into which the locking projections are fitted and fastened.

[0019] And in the infant container according to the present invention,

[0020] The entrance of the above fixed part is characterized by having a catch formed at the bottom of the groove.

[0021] Also, in the infant container according to the present invention,

[0022] The above fitting part is characterized in that the left-right width is formed larger than the left-right width of the locking projection.

[0023] In addition, in the infant container according to the present invention,

[0024] The above locking part is characterized in that the vertical width of the entrance side is formed to be larger than the vertical width of the locking projection, and the vertical width is formed to gradually decrease as it goes upward.

[0025] The infant container according to the present invention is:

[0026] It increases user convenience by using a one-touch detachment method rather than the conventional screw connection method.

[0027] Despite the simple connection method of the hanging structure, the gap between the container and the stopper member is completely sealed, preventing the liquid contents inside the container from leaking out.

[0028] It is especially effective in maximizing its utility as a baby bottle.

[0048] Hereinafter, a container for infants according to the present invention will be described with reference to the attached drawings.

[0049] The present invention relates to a container for infants as illustrated in FIGS. 1 to 3, and although a baby bottle is shown as a representative container for infants in the drawings of this specification, it is not limited thereto, and if it is a form that can be applied by combining a cap member (20) having a stopper member made of a flexible material such as silicone into a container-shaped body (10), or a form that can be combined using a locking projection (12) of a container-shaped body (10) and a locking groove (21) of a cap member (20) without a stopper member, it should be interpreted as being included in the scope of the rights of the present invention.

[0050] Specifically, the present invention,

[0051] Container-shaped body (10),

[0052] Including a cap member (20) coupled around the spout part (11) of the above container-shaped body (10),

[0053] The above container-shaped body (10) includes a plurality of locking projections (12) protruding from the circumference of the spout (11),

[0054] The above cap member (20) comprises a fitting part (211) formed upward from the lower end of the inner surface, a locking part (212) connected in an upwardly inclined direction in one direction from the upper end of the fitting part (211), and a fixing part (213) connected horizontally from one end of the locking part (212), and includes a plurality of locking grooves (21) into which the locking projection (12) is fitted and fastened.

[0055] As previously explained, the specific type or shape of the stopper member fitted into the cap member (20) may vary depending on the type of container.

[0056] In this specification, a nipple (30) for feeding is described as a representative plug member with reference to FIGS. 1 to 3, and the nipple (30) for feeding includes a lower flange (31) protruding outward from the lower end.

[0057] First of all, the above container-shaped body (10) has no restrictions on its shape or size and is made of a hard material such as PPSU or PP. However, unlike a typical container, there are no screw threads on the outer surface of the upper spout (11), and instead, a plurality of locking protrusions (12) are provided protruding.

[0058] The above locking projection (12) is a pseudo-semicircular or rectangular projection having a flat, flat surface shape with a left-right thickness that is wider than the top-down thickness. In order to ensure smooth coupling, the outer corners (121) are formed to be rounded to a predetermined R value based on the flat surface, and the outer ends between the corners (121) are formed as flat surfaces (122) for stable fixing through surface contact with the locking groove (21).

[0059] In the drawing, an embodiment in which a total of four locking protrusions (12) are radially arranged is representatively illustrated, but the present invention is not limited thereto.

[0060] Next, the locking groove (21) is a similar 'ㄱ' shape in which the locking portion (212) and the fixing portion (213) are connected counterclockwise in the fitting portion (211), and as the locking projection (12) passes the locking portion (212), the cap member (20) is tightened toward the lower side of the spout portion (11) of the container-shaped body (10), and the locking is completed at the fixing portion (213).

[0061] Specifically, the fitting portion (211) is formed so that the left-right width is larger than the left-right width of the locking projection (12), so that when the cap member (20) is fitted into the spout portion (11) of the container-shaped body (10), the locking projection (12) can be more easily fitted into the fitting portion (211).

[0062] Accordingly, when the locking projection (12) fitted into the fitting portion (211) moves along the locking portion (212) through the rotation of the cap member (20), the cap member (20) is pressed toward the container-shaped body (10) due to the inclination angle of the locking portion (212), and the cap member (20) and the container-shaped body (10) are coupled.

[0063] And the locking part (212) is formed so that the vertical width of the entrance side is larger than the vertical width of the locking projection (12), and the vertical width gradually decreases as it goes upward.

[0064] When the cap member (20) is first rotated and locked, the locking projection (12) moves smoothly, and the locking projection (12) is prevented from moving up and down within the locking portion (212) at the locking height of the cap member (20).

[0065] At this time, the inclination angle or overall length of the locking part (212) may vary depending on the diameter or height of the cap member (20), but more preferably, the inclination angle or overall length should be such that the locking of the cap member (20) can be completed within 1 / 4 rotation of the cap member (20), thereby ensuring safe locking of the cap member (20) while minimizing the rotation angle of the cap member (20).

[0066] In addition, the cap member (20) has an upper flange (22) that protrudes inwardly from the inner surface of the upper end, and the upper flange (22) protrudes inwardly in a downward slant to form a receiving groove (23) between the upper inner wall portion of the cap member (20).

[0067] Accordingly, when the cap member (20) is tightened to the spout (11) of the container-shaped body (10), the upper flange (22) of the cap member (20) presses the lower flange (31) of the feeding nipple (30), and the lower flange (31) is fitted so as to be in close contact with the receiving groove (23), thereby ensuring airtightness by being in close contact with the upper part of the spout (11) of the container-shaped body (10).

[0068] In this way, the cap member (20) is tightened and locked to the spout (11) of the container-shaped body (10), and then the locking projection (12) is fitted into the fixing portion (213) and fixed, thereby completing the locking of the cap member (20).

[0069] In addition, a catch (214) protruding from the bottom of the groove is formed at the entrance of the fixed part (213), and at this time, the vertical width of the fixed part (213) from which the catch (214) protrudes is formed to be equal to or slightly smaller than the vertical width of the locking projection (12).

[0070] Therefore, when the cap member (20) is rotated to lock, the locking projection (12) is forcibly fitted into the fixing member (213) by riding the catch (214).

[0071] In addition, the width of each of the upper, lower, left, and right sides of the remaining fixed part (213), excluding the entrance where the above-mentioned catch (214) protrudes, is formed to be equal to or slightly larger than the width of each of the upper, lower, left, and right sides of the above-mentioned locking projection (12).

[0072] Accordingly, when the cap member (20) is completely locked, the elastic force generated when the upper flange (22) of the cap member (20) presses the lower flange (31) of the feeding nipple (30) is applied, so that the locking projection (12) is firmly fitted into the fixing portion (213) and caught on the catch (214), so that the cap member (20) is not opened while maintaining the locked state unless a certain amount of external force is applied in the opening direction of the cap member (20).

[0073] Ultimately, the fastening of the cap member (20) is completed when the locking projection (12) passes over the locking portion (212), goes over the catch (214), and is fitted into the fixing portion (213). Consequently, compared to the conventional screw fastening method, the distance between locking and releasing of the cap member (20) is shortened, thereby increasing convenience of use.

[0074] In describing the present invention above, the container for infants has been mainly described with reference to the attached drawings, but the present invention can be modified, changed and substituted in various ways by those skilled in the art, and such modifications, changes and substitutions should be interpreted as falling within the scope of protection of the present invention.
