Description

  The present invention relates to a hinge cap that is attached to the mouth of a container and has an upper lid that is provided continuously through a hinge to open and close the spout, and in particular, a rib for collecting the liquid adhering to the back surface of the upper lid is provided to prevent dripping. The present invention relates to a hinge cap.

The hinge cap that connects the cap body and the upper lid attached to the mouth of the container with a hinge can be opened and closed simply by rotating the upper lid, and the upper lid is not lost, so it is widely used as a cap. .
However, when containing the content liquid to be used by shaking the container as in dressing or the like, the stirred content liquid adheres to the back of the top wall of the upper lid, and when the upper lid is opened and closed, the adhered liquid There was a problem of flowing out and soiling the periphery of the cap and the container body.

  In order to prevent such dripping at the time of opening and closing the upper lid, a plurality of liquids are provided on the back surface of the lid body 13 that fits into the dispensing cylinder 8 of the cap body 1 and projecting at intervals that allow the content liquid to adhere and be held.

JP 2001-106251 A

However, the liquid held between the plurality of liquid retaining pieces described in Patent Document 1 falls due to an impact at the time of closing the lid, or the tip of the liquid retaining piece is part of a cap body such as a dispensing cylinder. Since the liquid only flows down from the contacted part, the content liquid with high surface tension and viscosity is not collected in the container while remaining in the gap between the liquid retaining pieces, and is unsanitary and unsatisfactory.
On the other hand, in the case of a content liquid having a small surface tension and viscosity, the force to hold the adhering liquid in the gap is weak, and the liquid may spill if the impact of the opening / closing operation is large.

  An object of the present invention is to provide a hinge cap capable of solving the above-mentioned problems and efficiently collecting the liquid adhering to the inside of the sealing cylinder on the back surface of the upper lid in the container body to prevent dripping and keep the periphery of the cap clean. The purpose is to provide.

In order to solve the above-described problems, the present invention provides a hinge cap including a cap body attached to a mouth portion of a container body and an upper lid connected to the cap body via a hinge as a hinge cap with a liquid recovery rib. In addition, on the back surface of the top wall of the upper lid, a sealing cylinder is provided that fits to the inner periphery of the extraction cylinder of the cap body when the lid is closed, and seals the outlet. A plurality of liquid recovery ribs protruding from the back surface are arranged to be spaced apart from each other at the end opposite to the hinge, and converged to the inner periphery of the sealing cylinder while narrowing each other toward the hinge side. The protrusion height of the liquid recovery rib is low at the end and increases toward the converging part on the hinge side, and protrudes inward to the inner peripheral surface of the sealing cylinder where the liquid recovery rib is converging and continuously provided. A configuration characterized in that vertical ribs are provided is adopted.

As an embodiment of the liquid recovery rib, the protruding height of the liquid recovery rib is the highest in the central rib at the center position, and is lower as it goes away from the center, and the end of the liquid recovery rib Adopts a configuration characterized in that it extends at least from the center of the sealing cylinder to a region opposite to the hinge.

As another embodiment of the hinge cap with the liquid recovery rib, the liquid recovery rib or the longitudinal rib is provided on the hinge side of the sealing cylinder over a predetermined arc range having a substantially central position where the liquid recovery ribs are converged and continuously provided. The structure characterized by providing a tongue piece projecting inward below and below any of the above is adopted.

  The hinge cap with a liquid recovery rib according to the present invention has a plurality of liquid recovery ribs protruding from the back of the top wall inside the sealing cylinder of the upper lid, from the end opposite to the hinge arranged at a distance from the hinge side. The liquid adhering to the back surface of the top wall is guided to the liquid recovery rib protruding from the back surface, and the distance between the ribs. As the surface area gradually decreases, the surface area increases and the surface tension increases, so it is attracted to the converging part where the interval is narrowed, and the ribs converge to flow down the inner periphery of the dispensing cylinder at the continuous part where the surface area is reduced. The content liquid can be efficiently recovered.

The liquid recovery rib increases the protruding height toward the converging part on the hinge side, thereby facilitating the flow of liquid from the end of the rib to the converging part, and can further increase the suction force of the liquid to the converging part. .
In addition, by providing a tongue piece that protrudes inward over a predetermined arc range in which the liquid collection ribs of the sealing cylinder are converged and connected in a central position, the inside of the sealing cylinder Adhering liquid flowing down the circumference can be temporarily received on the tongue piece, and dripping can be reliably prevented.

A curved portion 28 is formed at the upper end of the dispensing cylinder 6, and the opposite side of the hinge C is slightly higher than the hinge C side to form the dispensing side flow path surface.
The lid engaging portion 10 erected on the upper surface of the base wall 9 has a substantially cylindrical shape, and a bulging portion 29 that engages with the upper lid B protrudes outward from the upper end portion.

As shown in FIGS. 1 to 3, the upper lid B is composed of a top wall 31 and a side peripheral wall 32 suspended from the periphery of the top wall 31. A sealing cylinder 33 which is fitted into the inner periphery of 6 is suspended.
As shown in FIG. 3A, a plurality of liquid recovery ribs 35 (35 a, 35 b,... 35 e) protruding from the back surface of the top wall 31 are provided inside the sealing cylinder 33, and each liquid recovery rib is provided. As shown in FIG. 4 (b), 35 has a wall surface shape with a predetermined height in cross section, and is arranged to be spaced apart from each other at the end 36 on the opposite side of the hinge C. While narrowing each other toward each other, the respective base portions are converged and connected to the inner peripheral surface of the sealing cylinder 33.

The liquid recovery ribs 35 extend from the base on the hinge C side at substantially equal intervals so that the liquid recovery ribs 35 are distributed almost uniformly on the back surface of the top wall 31 in the sealing cylinder 33, and the end 36 thereof is at least of the sealing cylinder 33. It extends from the center to a region opposite to the hinge C.
The protrusion height of each of the liquid recovery ribs 35 is low at the end 36, and gradually increases toward the base on the hinge side, and at the center line XX common to the cap body A and the upper lid B. The center rib 35c that coincides or is closest is the highest, and the distance from the center line is lower.
As shown in FIG. 3A, at the base of each liquid recovery rib 35, the intermediate ribs 35b and 35d are first converged on the central rib 35c in the order close to the central rib 35c, and then the peripheral ribs 35a and 35e are formed. Focusing on the central rib 35 c, the base of the central rib 35 c is connected to the vertical rib 37 projecting from the inner peripheral surface of the sealing cylinder 33.
In the present embodiment, five liquid recovery ribs 35 are provided, but the number of the liquid recovery ribs 35 can be determined as appropriate depending on properties such as the surface tension and viscosity of the content liquid.
Further, the specific shape, height, thickness, and extending region of the liquid recovery rib 35 are not limited to the present embodiment, and the vertical rib 37 is not necessarily required.

As shown in FIG. 2, the protruding height of the lower end 38 of the sealing cylinder 33 from the back surface of the top wall 31 increases from the opposite side of the hinge C toward the hinge C side. Is provided with a tongue piece 39 that protrudes inward over a predetermined arc range having a longitudinal rib 37, which is formed by converging and collecting the liquid recovery ribs 35, as a central position.
In the present embodiment, the tongue piece 39 is provided at the lower end 38 of the sealing cylinder 33, but it does not necessarily have to be provided at the lower end 38, and may be provided at an intermediate portion as long as it is below the liquid recovery rib 35. Good.

It consists of a part 43 and reinforcing ribs 44 provided at a plurality of locations of the lightening part 43 and connecting between the outer frame 42 and the side peripheral wall 32.
On the inner periphery of the side peripheral wall 32, engaging protrusions 45 that engage with the bulging portion 29 of the lid engaging portion 10 of the cap body A are respectively provided at intermediate portions between the hinge C side and the knob portion 40 side. Projects over the arc range.

Next, usage modes and operational effects of this embodiment will be described.
The cap of the present embodiment is attached by being plugged into the mouth portion 1 of the container body D in the closed state shown in FIG.
In the plugging process, the mouth 1 of the container body D is applied to the annular groove formed between the inner cylinder 7 and the outer cylinder 8, and pressing force is applied from above the upper lid B, so that the outer cylinder 8 is fitted. The strip 2 gets over the mouth portion 1 and fits into the constricted recess 2, and the mouth portion 1 is clamped by the outer periphery of the inner tube 7 and the inner periphery of the outer tube 8, and the base wall 9 and the fitting protrusion 25. Is done.

At that time, when it is necessary to position the pouring direction of the cap main body A with respect to the container main body D, the alignment ribs 27 provided on the outer periphery of the outer cylinder 8 coincide with a predetermined portion (not shown) of the container main body D. Positioning is performed.
Although the cap of the present embodiment is formed thin as a whole, since the reinforcing protrusion 26 is provided on the fitting protrusion 25, the fitting strength can be maintained even if the outer cylinder 8 is thin. it can.

In order to unplug the cap of this embodiment when the container is used, as shown in FIG. 2, the upper lid B is opened, the pull ring 17 is pulled upward, the removal portion 15 of the partition wall 5 is pulled up via the support column 16, and the thinned portion is weakened. 14 is cut, the removal part 15 is cut off from the partition wall 5, and the spout is opened.
Since a thin plate-like buffer portion 18 is provided on the lower side of the pull ring 17 opposite to the hinge C, the buffer portion 18 can be easily bent when the finger hits it, and the contact pressure on the finger can be softened. .

When pulling up the pull ring 17, the periphery of the removal portion 15 adjacent to the thinned weakened portion 14 is formed thick by the upper protrusion 19 except for the periphery of the support column, so that the fracture portion in the thinned weakened portion 14 bends or extends. Therefore, it is possible to prevent the beard from being generated, and the removal unit 15 can be easily cut off.
Further, since the constricted portion 21 of the removing portion 15 is formed thick and reinforced by the lower protrusion 23, the constricted portion 21 may be broken while the pull ring 17 is being pulled up even if the entire removing portion 15 is thin. There is nothing.

If the content liquid contained in the container body D is agitated by shaking the container before use, such as dressing, after removing the removing portion 15 from the partition wall 5 and opening the spout, the upper lid B is once closed. After shaking the container, the upper lid B is opened again, the container is tilted, and the content liquid is poured out.
When the upper lid B is closed, a sealing cylinder 33 suspended from the back surface of the top wall 31 of the upper lid B is fitted into the inner peripheral surface of the extraction cylinder 6 to seal the inside of the container, and on the inner peripheral surface of the side peripheral wall 32. The provided engaging protrusion 45 gets over the bulging portion 29 of the lid engaging portion 10 and engages with the lower portion of the bulging portion 29 to hold the closed state.
When the upper lid B is opened and closed, the knob portion 40 to which a finger is applied is formed thin by the thinned portion 43, but sufficient strength is ensured by the reinforcing rib 44.

The content liquid stirred when the container is shaken flows out from the spout and adheres to the inside of the sealing cylinder 33 on the back surface of the top wall 31.
The adhering liquid flows down while being guided to a plurality of liquid recovery ribs 35 (35a, 35b,... 35e) protruding from the back surface of the top wall 31, and the surface area density is gradually reduced as the distance between the liquid recovery ribs 35 gradually decreases. Is increased and the surface tension is increased, so that the liquid recovery rib 35 is sucked toward the respective bases.
Since the intermediate ribs 35b and 35d and the peripheral ribs 35a and 35e are connected to the vertical ribs 37 on the inner periphery of the sealing cylinder 33 while converging on the central ribs 35c at the respective base portions to reduce the surface area, The liquid that has flowed down along the recovery rib 35 immediately flows down from the central rib 35 c to the vertical rib 37 and is recovered in the container body D.

At this time, the protruding height of each liquid recovery rib 35 is low at the end 36 opposite to the hinge C and is high toward the converging portion of each base on the hinge C side, and thus the liquid recovery rib 35 adheres to each liquid recovery rib 35. The liquid thus urged to flow down to the respective bases and the suction force to the vicinity of the converging site are enhanced, so that the content liquid can be efficiently recovered.
Further, by making the protruding height of the central rib 35c higher than that of the intermediate ribs 35b and 35d and the peripheral ribs 35a and 35e, the adhered liquid becomes taller from the short intermediate ribs 35b and 35d and the peripheral ribs 35a and 35e. It can be guided to flow down to the central rib 35 c and further flow down to the vertical rib 37 on the inner periphery of the sealing cylinder 33.

Further, the lower end 38 of the sealing cylinder 33 is provided with a tongue piece 39 projecting inward over a predetermined arc range having a central position in the vicinity of the longitudinal rib 37 where the liquid recovery ribs 35 are converged and continuously provided. When the upper lid B is tilted during opening and closing, the liquid flowing down the inner peripheral surface of the sealing cylinder 33 can be temporarily received on the tongue piece 39, and the liquid stored in the tongue piece 39 is poured out when the lid is closed. Since it is collected in the container through 6, it is possible to prevent dripping.
Although the tongue piece 39 is provided at the lower end 38 of the sealing cylinder 33, the tongue piece 39 does not necessarily have to be the lower end, and may be provided at an intermediate portion below the vertical rib 37.

In this embodiment, the upper protrusion 19 that reinforces the removing portion 15, the lower protrusion 23, the reinforcing support portion 26 that reinforces the fitting protrusion 25 of the outer cylinder 8, and the reinforcing rib 44 that reinforces the lightening portion 43 of the knob 40. Etc., the entire cap can be made thinner.
In addition, the shapes of the extraction tube 6, the lid engaging portion 10, the removal portion 15 that forms the spout are not limited to those shown in the present embodiment, and various shapes can be used as necessary. Can be adopted.

The hinge cap according to the present invention can efficiently recover the liquid adhering to the back surface of the upper lid by guiding it to a plurality of liquid recovery ribs, allowing it to flow down into the container and reliably preventing dripping. It can be widely used as a hinge cap for containers.
In particular, it is suitable for use as a hinge cap for a container for storing a content liquid to be used by shaking and agitating a container such as dressing, various sauces and soup.
