The present invention relates to a plug with a built-in unsealing blade with a tamper-proof opening protruding from the top of a liquid paper container used for seasonings and the like. 2. Description of the Related Art Conventionally, as shown in FIG. 3 (a), for example, a liquid paper container (20) has a square pillar-shaped body (21) and a gable roof-shaped top inclined plate (21). No. 22), in which a spout with a built-in opening blade (10) is protruded for ease of pouring, has been used in a wide range of commercial fields. For example, as shown in FIG.
A plurality of triangular-shaped opening blades (310) are provided at the lower end with the cutting edge portion (31).
A cap (200) screwed down to the spout (100) (the spouting tool) inside the spouting tube (110) so as to be able to descend and open the vertically opening tubular body (300) provided with 1).
When the is rotated in the unscrewing direction, the spiral sliding contact inclined surface provided on the outer peripheral surface of the guide inner cylinder vertically provided at the center position of the top plate of the cap, and the inside of the opening cylindrical body The opening cylinder (300) is lowered by sliding contact with the spiral sliding contact guide inclined surface provided on the peripheral surface, and the liquid sheet is opened by the opening blade (310) provided at the lower end of the opening cylinder. It has been known that a sealing film (400) for sealing a container is opened by breaking. The reason why the notch portion is provided is to prevent broken pieces (401) of the sealing film from falling into the contents (30). Then, into the opening blade built-in plug, a sealing film is heat-sealed on the lower surface of the spout to seal the lower opening of the dispensing cylinder, and the stopper is poured into the stopper mounting hole of the liquid paper container. An internal one that is formed by projecting the cylinder and heat-sealing the upper surface of the flange to the inner surface of the container, and a sealing film (40) of the liquid paper container (20) as shown in FIG.
On the upper surface of the outer peripheral edge of the pouring hole (23) sealed in 0), there is an external type which is attached by heat-sealing the lower surface of the flange (120) of the spout (100). However, since the above-mentioned conventional opening blade built-in plug does not have a function for preventing unauthorized opening, even if the product is accidentally or intentionally opened in the distribution process, the product is not opened. Is difficult to judge from the appearance of the product, the virginity of the product may be impaired, or the contents of the product may be adversely affected. For this reason, the present inventors have found that when a cap is screwed onto a spout, the cap is screwed into the spout and the cap is unscrewed from the spout in order to provide the conventional opening blade built-in plug with a function to prevent unauthorized opening. In the past, a tamper evident ring with a tamper evident ring connected to the lower end of the cap via a plurality of thin brittle bridges, and a tamper evident ring remaining on the spout side separated from the cap, has been prototyped. If the engagement is tight, a setting failure may occur in the capping process, and if the engagement with the spout is weakened, a failure in separating the tamper-evident ring may occur when the cap is unscrewed. The present invention solves the above-mentioned conventional problems, has a function of preventing unauthorized opening, has good set suitability in the capping process, and the unauthorized opening preventing ring is completely separated from the cap when the cap is unscrewed. It is intended to provide a plug with a built-in opening blade with tamper-proofing. [0005] That is, the present invention comprises a spout having a built-in unsealing cylinder and a cap screwed to the spout, which is protruded at a pouring position of a liquid paper container. When the cap is rotated in the unscrewing direction, an unsealing cylinder having an unsealing blade at a lower end, which is built in the inside of the spout spout cylinder, descends with the rotation of the cap and is provided below. In the spout for breaking the sealing film and opening the container, the cap is provided at the lower end of the peripheral wall at a lower end thereof through a plurality of thin brittle bridges that are cut when the cap is rotated in the unscrewing direction. A tamper-evident ring having an engaging portion on the peripheral surface is connected, and when the spout is screwed to the spout below the threaded portion on the outer peripheral surface, the tamper-evident ring of the cap is engaged. To provide an engaging part A step is provided at a position 20 to 60% of the height from the lower end of the tamper-evident ring of the cap, and the lower outer radius is set to 20 to 7 of the thickness higher than the upper outer radius.
A plug with a built-in unsealing blade with tamper-proofing, which is reduced by 0%. Next, an embodiment of a plug with a built-in unsealing blade with tamper-proof according to the present invention will be described in detail with reference to the drawings. FIG. 1 is a partial cross-sectional view showing the structure of a plug with a built-in unsealing blade with tamper-proof according to one embodiment of the present invention.
Is a front view thereof. As shown in FIG. 1 (a) or FIG. 2, an opening cylinder (10) having an opening blade (310) at the lower end of an opening plug with built-in opening blade (10) according to one embodiment of the present invention. (30
0) movably housed therein, and a cap (200) screwed onto the spout. The cap is provided at the lower end of the peripheral wall (220) via a plurality of thin brittle bridges (223) at the lower end. A tamper-evident ring (230) having an engaging portion (231) on the surface is connected to the top plate (210).
At the center of the lower surface, a guide inner cylinder (240) having two or more sliding guide slopes (241) opposed to each other for lowering the opening cylinder on the outer peripheral surface are provided at regular intervals in the circumferential direction. The opening cylindrical body has a sliding guide inclined surface (24) of the cap on the inner peripheral surface.
A plurality of sliding guide inclined surfaces (301) corresponding to (1) are provided at equal intervals in the circumferential direction, and usually, a plurality of sliding protrusions (320) are provided at the upper end of the outer peripheral surface at equal intervals in the circumferential direction. The spout generally has eight sliding vertical ribs (130) corresponding to the sliding projections (320) of the opening cylinder on the inner peripheral surface of the pouring cylinder (110) at equal intervals in the circumferential direction. And an engaging portion (11) in which the engaging portion (231) of the tamper-evident prevention ring of the cap engages by fitting or occlusion below the screwing portion (111) on the outer peripheral surface.
2) is provided. Also, as shown in FIG. 1B, from the lower end of the tamper-evident ring (230) of the cap,
A step (232) is provided from a position of 20 to 60% of the height (H), and the lower outer radius is reduced by 20 to 70% of the thickness (T) above the upper outer radius. When the cap is rotated in the unscrewing direction, the cap rises, but the tamper-evident ring is attached to the spout. Due to the engagement, the plurality of thin brittle bridges connecting the lower end of the peripheral wall of the cap and the tamper-evident ring are cut by the rotational force of the cap, and the cap and the tamper-proof ring are separated. At the same time, the sliding contact between the sliding guide inclined surface of the cap and the sliding guide inclined surface of the opening cylinder lowers the opening cylinder to open the sealing film sealing the lower container. The container is opened by breaking at the opening blade provided at the lower end of the cylinder. And
After the contents are used as needed, the cap is screwed onto the spout to reseal the container. The fact that the thin-walled fragile bridge has been cut can be clearly confirmed from the appearance, so whether or not the container has been opened previously can be determined based on the presence or absence of the thin-walled fragile bridge, ensuring the virginity of the product. And can be confirmed. Further, in the plug with a built-in opening blade with tamper-proof of this embodiment, a step is provided at a position of 20 to 60% of the height from the lower end of the tamper-evident ring of the cap, and the outer peripheral radius below the step is set. The thickness of the lower portion is reduced by reducing the upper outer radius by 20 to 70% of the thickness of the upper portion. As a result, when the cap is screwed into the spout and set, the engaging portion provided on the inner peripheral surface at the lower end of the tamper-evident prevention ring is positioned below the threaded portion on the outer peripheral surface of the spout pouring cylinder. It becomes easy to get over the provided engaging portion appropriately, and the setting suitability is improved.
Moreover, the tamper-evident ring is not simply a thinner whole, but, as described above, the lower part of the tamper-evident ring is based on knowledge obtained from the inventors' repeated trial production.
When the cap is rotated in the unscrewing direction, the engaging portion of the tamper-evident ring does not climb over the engaging portion of the spout. The cap is reliably cut by the rotational force, and the cap and the tamper-evident ring are separated. [0010] When a step is provided from the lower end of the tamper-evident ring to a position 60% or more of the height and the outer peripheral radius is reduced below, the rigidity of the tamper-evident ring becomes weak, and the cap is unscrewed in the unscrewing direction. When rotated, the tamper-evident ring may get over the engagement part of the spout without cutting the thin brittle bridge. Also, a step is provided from a position of 20% or less of the height and the outer periphery is provided below. If the radius is reduced, the rigidity of the tamper-evident prevention ring is high, and when the cap is screwed into the spout and set, the engagement force with the spout is strong, so that setting failure may occur. Further, when the lower outer radius is made 70% or more of the upper thickness, the rigidity of the tamper-evident ring becomes weak, and when the cap is rotated in the unscrewing direction, the thin fragile bridge is not cut, and The opening prevention ring may get over the engagement part of the spout,
If the lower outer radius is set to 20% or less of the upper thickness, the tamper-evident ring has high rigidity, and when the cap is screwed into the spout, the engagement force with the spout is strong. May occur. The tamper evident plug of the present invention has a tamper evident function by connecting a tamper evident ring to the lower end of the peripheral wall of the cap via a plurality of thin brittle bridges. By making the lower part of the tamper-evident ring thinner with the restriction range, the suitability for setting in the capping process is improved, and the tamper-evident ring is completely separated from the cap when the cap is unscrewed.
