Description

[Technical Field]

[0001] The present invention relates to a melt-combining cap, and more particularly to a melt-combining cap having a new configuration for preventing consumers from opening a container containing contents such as tablets and for verifying whether the container has been opened or not during handling. [Background technology]

[0002] Generally, health supplements such as digestive aids and vitamins are manufactured in the form of tablets or pills (hereinafter referred to as tablets). Tablets are taken regularly in a fixed amount to maximize their effectiveness and to prevent overuse.

[0003] Such tablets are sold in a designated storage container, but conventional tablet storage containers have a structure including a container body that stores a large number of tablets and a cap that is connected to the inlet of the container body in an openable and closable manner.

[0004] Therefore, in order to take a tablet, the cap must be opened from the container body, and then the tablet contained in the container body must be pulled out and taken.

[0005] However, there are cases where consumers voluntarily open the cap while carrying or handling a medicine container containing tablets, and currently there are insufficient means for checking whether the cap has been opened. Summary of the Invention [Problem to be solved by the invention]

[0006] SUMMARY OF THE INVENTION An object of the present invention is to provide a novel melt-combined cap for consumer tamper-evident and tamper-evident functionality during handling of a container containing contents such as tablets. [Means for solving the problem]

[0007] In order to solve the above problems, the present invention provides a melt-combining cap, which includes a lower cap (124) that is attached to the upper opening of a container (20) in which tablets are stored, and an upper cap (122) that is attached to the lower cap (124), and is configured so that the tablets stored in the container (20) can be taken out by removing the upper cap (122).

[0008] At least one closed-loop type forced assembly protrusion (125) is provided on the outer peripheral surface of the lower cap (124), and the closed-loop type forced assembly protrusion (125) is forcibly inserted into at least one container-side protrusion engagement groove (22) provided on the inner peripheral surface of the container (20), thereby forcibly assembling the upper cap (122) and the lower cap (124) to the container (20).

[0009] The bottom surface of the upper cap (122) and the upper end of the lower cap (124) are connected by a plurality of ribs (126), and when pressure acts inside the container (20), even if only one of the plurality of ribs (126) ruptures, the remaining ribs (126) cannot withstand the pressure inside the container (20) and rupture naturally, causing the upper cap (122) to separate from the lower cap (124). [Effects of the Invention]

[0010] The present invention has the effect of preventing consumers from arbitrarily opening a cap while holding or using a container containing contents such as tablets, and of reliably confirming whether the cap can be opened or not. [Brief explanation of the drawings]

[0016] Referring to the drawings, the present invention includes a lower cap 124 coupled to the open top of a container 20 in which tablets are stored, and an upper cap 122 coupled to the lower cap 124, and is configured so that the tablets stored in the container 20 can be taken out by removing the upper cap 122. The tablets stored in the container 20 can be taken out by removing the upper cap 122 onto the lower cap 124.

[0017] The container 20 described in the present invention is cylindrical, the upper cap 122 is circular disk-shaped, and the lower cap 124 is circular ring-shaped with its upper end connected to the bottom surface of the upper cap 122 by a plurality of ribs 126.

[0018] At least one closed-loop type forced assembly protrusion 125 is provided on the outer peripheral surface of the lower cap 124, and the closed-loop type forced assembly protrusion 125 is forcibly inserted into at least one container-side protrusion engagement groove 22 provided on the inner peripheral surface of the container 20, thereby forcibly assembling the upper cap 122 and the lower cap 124 to the container 20.

[0019] The bottom surface of the upper cap 122 and the upper end of the lower cap 124 are connected by a plurality of ribs 126, and when pressure acts inside the container 20, even if only one of the plurality of ribs 126 bursts, the remaining ribs 126 cannot withstand the pressure inside the container 20 and burst naturally, causing the upper cap 122 to separate from the lower cap 124.

[0020] In the present invention, the upper cap 122 and the lower cap 124 are made of a material with appropriate self-elasticity, such as plastic or synthetic resin, and the plurality of ribs 126 are also made of the same material as the upper cap 122 and the lower cap 124, with the upper and lower ends of the plurality of ribs 126 being connected to the bottom surface of the upper cap 122 and the upper end of the lower cap 124, respectively. The plurality of ribs 126 are arranged at regular intervals in the circumferential direction based on the centers of the upper cap 122 and the lower cap 124. In the present invention, 24 ribs 126 are provided.

[0021] Referring to FIG. 5, the container 20 is assembled by forcibly inserting the upper cap 122 and the lower cap 124 into the open top end of the container 20, and when using tablets inside the container 20, the upper cap 122 is opened from the lower cap 124, and the tablets in the container 20 can be taken out and used.

[0022] The present invention is characterized by the forced assembly of the upper cap 122 and the lower cap 124. That is, as described above, at least one closed-loop type forced assembly protrusion 125 is provided on the outer circumferential surface of the lower cap 124. When the lower cap 124 is aligned to meet the upper open end of the container 20 and the upper cap 122 and the lower cap 124 are forced downward from the upper open end of the container 20, at least one closed-loop type forced assembly protrusion 125 provided on the outer circumferential surface of the lower cap 124 enters the center side of the lower cap 124 and then engages with the container-side protrusion engagement groove on the inner circumferential surface of the container 20. When the closed-loop type forced assembly protrusion 125 meets the container side protrusion engaging groove 22, the closed-loop type forced assembly protrusion 125 is seated and hooked into the container side protrusion engaging groove 22 due to the self-elastic restoring force of the lower cap 124 and the self-elastic restoring force of the closed-loop type forced assembly protrusion 125, and the closed-loop type forced assembly protrusion 125 of the lower cap 124 is forcibly inserted into at least one container side protrusion engaging groove 22 on the inner surface of the container 20, so that the upper cap 122 and the lower cap 124 can be forcibly assembled to the container 20.

[0023] In the present invention, two closed-loop type forced assembly protrusions 125 are provided on the outer circumferential surface of the lower cap 124. When the lower cap 124 is aligned to meet the upper end opening of the container 20 and the upper cap 122 and the lower cap 124 are forcibly pushed downward from the upper end opening of the container 20, the two closed-loop type forced assembly protrusions 125 provided on the outer circumferential surface of the lower cap 124 enter the center side of the lower cap 124 and then engage with the two container-side protrusion engagement grooves 22 provided on the inner circumferential surface of the container 20 for closed-loop type forced assembly. When the standing protrusions 125 meet, the self-elastic restoring force of the lower cap 124 and the self-elastic restoring force of the two closed-loop type forced assembly protrusions 125 cause the two closed-loop type forced assembly protrusions 125 to seat and engage in the two container side protrusion engagement grooves 22, and the two closed-loop type forced assembly protrusions 125 of the lower cap 124 are forcibly inserted into the two container side protrusion engagement grooves 22 on the inner surface of the container 20, so that the upper cap 122 and the lower cap 124 can be forcibly assembled to the container 20.

[0024] In addition, in the present invention, the closed-loop type forced assembly protrusion 125 has a lower guide tapered portion 125GT extending upward at least on the bottom surface when viewed from the side cross section of the upper cap 122 and the lower cap 124. This allows the closed-loop type forced assembly protrusion 125 to be inserted into the container-side protrusion engaging groove 22 while smoothly riding down the inner surface of the container 20 before entering the container-side protrusion engaging groove 22 at the moment when the upper cap 122 and the lower cap 124 are forcedly assembled by pushing them downward from the upper open portion of the container 20. This has the effect of making it easier to forcefully assemble the upper cap 122 and the lower cap 124 by pushing them downward from the upper open portion of the container 20.

[0025] For reference, the present invention can be forcefully fitted in an overcap form onto the caps of common PET mineral water bottles and all 28mm diameter caps on the market.

[0026] Meanwhile, in the present invention, the internal pressure of the container 20 is at a level of approximately 0.1 N. In the present invention, the number of ribs 126 is 24, and the 24 ribs 126 prevent the top cap 122 from peeling off (i.e., breaking). However, to prevent consumers from opening the container and to confirm whether it has been opened, even if only one of the 24 ribs 126 breaks, it will not be able to withstand the force of 0.1 N, and the remaining ribs 126 (i.e., the remaining 23 ribs 126) will naturally break over time, allowing the top cap 122 to be removed.

[0027] The present invention has the effect of preventing a consumer from arbitrarily opening the cap while holding a container 20 containing contents such as tablets, and of reliably confirming whether the cap has been opened. In this case, preventing a consumer from arbitrarily opening the cap mainly means preventing a consumer from arbitrarily opening the upper cap 122 due to mistake or the like, and checking whether the cap has been opened mainly means checking whether the upper cap 122 has been opened.

[0028] Meanwhile, FIG. 6 is a side cross-sectional view of a melt-combining cap according to another embodiment of the present invention, and FIG. 7 is a side cross-sectional view of a melt-combining cap according to yet another embodiment of the present invention.

[0029] The present invention is characterized by further including a closed-loop sealed channel portion 130 provided on the bottom surface of the top cap 122 .

[0030] The bottom surface of the upper cap 122 is provided with an inner channel-forming protrusion 132 protruding downward, and an outer channel-forming protrusion 134 protruding downward from the bottom surface of the upper cap 122 and positioned outside the inner channel-forming protrusion 132 so as to be concentric with the inner channel-forming protrusion 132. The inner channel-forming protrusion 132 and the outer channel-forming protrusion 134 form the sealing channel portion 130. A cap insertion space is provided between the inner channel-forming protrusion 132 and the outer channel-forming protrusion 134, into which the upper end of the lower cap 124 is inserted and coupled.

[0031] Therefore, the upper cap 122 is connected to the upper end of the lower cap 124 by a plurality of the ribs 126 (24 ribs 126 in the present invention), and the upper end of the lower cap 124 is fitted into the cap insertion space between the inner channel-forming protrusion 132 and the outer channel-forming protrusion 134, so that the inner channel-forming protrusion 132 and the outer channel-forming protrusion 134 are in sealing contact with the inner and outer peripheral surfaces of the upper end side of the lower cap 124, thereby further enhancing the sealing of the interior of the container 20 by the upper cap 122 and the lower cap 124.

[0032] The present invention is also characterized in that the bottom cap 124 further includes a closed loop type auxiliary sealing edge piece 142 provided on the periphery of the bottom end thereof.

[0033] When the upper cap 122 and the lower cap 124 are forcibly assembled by pushing them downward from the upper open end of the container 20, the closed-loop type auxiliary sealing edge piece 142 comes into sealing contact with the inner peripheral surface of the container 20, which is expected to further improve the sealing performance between the lower cap 124 and the container 20.

[0034] As described above, the present invention is not limited to the above-described embodiments, and it will be understood by those skilled in the art that various modifications and variations are possible without departing from the spirit and scope of the present invention.

[0035] Therefore, the above-described embodiments are provided to fully inform those skilled in the art of the present invention of the scope of the invention, and should be understood to be illustrative and not restrictive in all respects, and the present invention is defined only by the scope of the claims.
