Description

The present invention relates to a hinge cap that is used by being attached to a container body, and particularly to a hinge cap that has a transition plug that breaks a thin weakened portion and moves to the upper lid side when the lid is opened for the first time.

Conventionally, in a hinged cap consisting of a cap body attached to a container body and an upper lid connected to the cap body via a hinge, an opening for a spout is provided in a partition wall of the cap body to ensure the sealing performance of the container body. The planned portion was defined by a breakable thin-walled weakened portion and formed an opening portion provided with a pull ring or the like.
However, in order to open the cap, it is necessary to remove the cap by pulling up a pull ring after opening the top cover, which is time-consuming and difficult for users with weak strength to open the cap. There was a problem.

Therefore, it is conceivable to eliminate the opening part and open the spout in advance, but in this case, there will be a problem with the sealing of the container body, so the pull ring will be omitted and the transition as an opening part will be removed. A hinged cap is conventionally known in which the stopper is molded and then joined to the top cover using ultrasonic bonding or the like, and when the top cover is opened, the transition stopper is pulled up and the thin weakened portion is broken to open the seal (for example, as disclosed in patent literature (see 1).

In addition, in the hinge cap described in Patent Document 1, after molding, it is necessary to join the transition stopper to the top cover by ultrasonic bonding or the like, so that the lifting part of the transition stopper is connected to the hook attached to the top cover that hangs down from the top cover. There is also known a hinge cap in which the weakened part is broken and the seal is opened by pulling up the transition stopper together with the lifting part, as well as opening the top cover (for example, see Patent Document 2).

Furthermore, an insert body of a separate member may be used, for example, the insert body may be inserted through the engagement hole 36 and combined with the transition plug 10 (pulling part 12), in short, the transition plug 10 and the upper lid B may be Any method may be used as long as it can be firmly bonded.

An arcuate knob 38 is provided on the outer periphery of the lower end of the front side of the side peripheral wall 31, and as shown in FIG. A locking convex portion 39 that engages with the inner peripheral side of the joint portion 22 is provided vertically, and an engaging recess 40 that engages with the bulge portion 23 of the lid engaging portion 22 to maintain the lid closed state is provided in the center. It is surrounded.

Although not shown, the hinge cap of this embodiment is provided with a shrink label, a sealing member, etc. between the cap body A and the top lid B in order to prevent unauthorized opening before use.

Next, the usage mode and effects of this embodiment will be explained.
The hinge cap of this embodiment is manufactured in one piece by injection molding using a mold.
The hinge cap of this example manufactured by integral molding is obtained in an open state as shown in FIG. 2, and is turned into a closed state as shown in FIG. 1 by rotating the top cover B via the hinge C. Ru.
At this time, since the locking protrusion 16 on the upper part of the pulling part 12 is tapered upward, it easily enters into the locking part 33, and the upper part reaches the engagement hole 36, and the locking protrusion 16 16 fits within the inner circumference of the engaging part 33, and the lower surface 33a of the engaging part 33 contacts or approaches the stepped part 15 of the pulling part 12.
Furthermore, the upper end of the outer periphery of the holding wall 13 engages with or abuts the lower end of the inner periphery of the holding wall 34 , and the upper end of the holding standing wall 13 contacts or approaches the lower end of the contact rib 35 .

In addition, the sealed envelope 32 forms a sealing part in close contact with the pouring tube 6, and the lid engaging part 22 of the cap body A fits into the locking protrusion 39 and the engaging recess 40 of the upper lid B. Then, the lid becomes closed.
In this embodiment, when the lid is closed, the upper part of the locking protrusion 16 is treated to prevent it from coming off by melting, ultrasonic bonding, etc., and as shown in FIG. 33.
Next, the closed hinge cap is plugged and attached to the opening 1 of the container main body D filled with the liquid content.

When the hinge cap of this embodiment is used for the first time, by opening the top cover B, the thin weakened portion 8 provided on the partition wall 5 of the cap body A can be broken and opened.
First, when you put your finger on the knob 38 of the top cover B and lift it up, the bottom wall 11 on the front side is lifted, and the thin weakened part 8 on the front side begins to break.By further lifting the top cover B, the hinge C direction The thin weakened portion 8 continues to break, and finally the thin weakened portion 8 near the hinge C is broken, and the transition plug 10 is removed from the partition wall 5 and transferred to the upper lid B, where it is held. In the cap body A, the trace of the transfer stopper 10 removed from the partition wall 5 serves as a spout, and the liquid inside the container body D can be poured out.
After the transition stopper 10 is opened, when the top lid B is closed again, the outer periphery of the sealed envelope 32 of the top lid B comes into close contact with the inner periphery of the spout cylinder 6 of the cap body A, and the inside of the spout cylinder 6 is closed. can be sealed.

In this embodiment, since the reinforcing rib 14 is provided on the hinge C side of the pull-up portion 12, stress is concentrated on the thin weakened portion 8 on the front side, making it easy to break the thin weakened portion 8.
Furthermore, in this embodiment, the front end portion 11a of the bottom wall 11 on the front side has a pointed shape, so that stress tends to concentrate on the thin weakened portion 8 on the front side.

In the case of seasonings such as dressings and sauces, the hinge cap of this embodiment is attached to the top lid B when the container body D is shaken up and down with the lid closed in order to stir the content liquid. In the transfer stopper 10, the liquid content adheres to the lower surface of the bottom wall 11 and the tongue piece 19, but some of the liquid content remaining on the lower surface of the bottom wall 11 flows along the inner circumferential surface 19b of the tongue piece 19 to the container body. It flows down into D.
In addition, when the transition stopper 10 is in a closed state, the liquid tends to remain attached to the horizontal bottom wall 11 compared to the vertically installed tongue piece 19, but as shown in FIG. 4, when the top cover B is opened, Since the bottom wall 11 is inclined toward the hinge C side, the liquid remaining on the bottom wall 11 flows down toward the inner circumferential surface 19b of the tongue piece 19 and reaches the corner between the bottom wall 11 and the tongue piece 19. Content liquid α accumulates.

Next, by tilting the container body D toward the front with the upper lid B left open, the liquid inside the container body D can be poured out through the spout tube 6.
At this time, when the tongue piece 19 tilts from the horizontal state to the lower left when viewed from the horizontal position in FIG. The portion is guided inward of the spouting tube 6 along the tip 19a of the tongue piece 19, so that the content liquid α flowing down the tongue piece 19 does not adhere to the periphery of the spouting tube 6 and flows into the container body D. can be recovered.

In this example, in order to confirm the effect of the tongue piece 19 provided on the transition stopper 10, the length of the tongue piece 19 was Two types of hinge caps with L set to 3 mm and 10 mm were created, and an experiment was conducted to compare each hinge cap after the first stirring and after the 10th stirring.
The liquid content used in the experiment was a grilled meat sauce, and the hinge cap was for a container main body D with an inner diameter of 20 mm at the mouth 1, and the material was LLDPE (linear low-density polyethylene) resin.

This comparative experiment yielded results as shown in the photograph shown in FIG.
The photographs in Figures 5(a) to 5(d) show the state in which the hinge cap is opened after shaking the container body D up and down to stir the contents, with the cap body A on the left and the top lid B on the right. It is.
According to this comparative experiment, as shown in FIGS. 5(a) and (b), when the length L of the tongue piece 19 is 3 mm, after the first stirring (a), the tip of the cap body A is Although the liquid content does not adhere to the outside of the dispensing tube 6 and the outside of the sealed envelope 32 of the top lid B, after the 10th stirring (b), the liquid does not adhere to the outside of the dispensing tube 6 of the cap body A and the sealed envelope 32 of the top lid B. It can be seen that a large amount of liquid is attached to the outside of the container.
On the other hand, as shown in FIGS. 5(c) and 5(d), when the length L of the tongue piece 19 is 10 mm, after the first stirring (c), the dispensing tube of the cap body A is Naturally, the content liquid does not adhere to the outside of the spout tube 6 of the cap body A and the outside of the sealed envelope 32 of the top lid B, even after the 10th stirring (d). It can be seen that the content liquid hardly adheres to the outside of 32.
From the above experimental results, if the length L of the tongue piece 19 is 3 mm or less, the effect is poor, and it is preferable to set it to about 4 mm to 15 mm.

In addition, in this embodiment, the outer periphery of the holding vertical wall 13 of the transition stopper 10 engages with or contacts the inner periphery of the holding wall 34 of the top lid B, so that the rear end 11b of the bottom wall 11 can be firmly held. Therefore, the spout is closed by the bottom wall 11, and the rear end 11b of the bottom wall 11 is not easily deformed even if the container main body D is tipped sideways or shaken greatly, so that the liquid content does not touch the bottom wall 11. It becomes difficult for the liquid to enter through the gap with the partition wall 5, and even if the liquid enters through the gap between the bottom wall 11 and the partition wall 5, the holding vertical wall 13 prevents the liquid from flowing into the transfer stopper 10, so it is difficult to open the lid again. Even in this case, the inside and outside of the container main body D are prevented from being contaminated by the liquid content.

Furthermore, in this embodiment, the holding wall 34 of the upper lid B has an abutting rib 35 formed at the center of the inner periphery on the side of the hinge C, and the abutting rib 35 is such that the inner periphery of the holding wall 34 is connected to the transition stopper 10. Since it is provided so as to be close to or in contact with the upper end of the holding standing wall 13 when engaging or abutting the outer periphery of the holding standing wall 13, even if the top wall 30 of the upper lid B is pushed in, the holding standing wall 13 and the holding receiver are not connected to each other. Disengagement from or contact with the wall 34 can be suppressed.
In this embodiment, the contact rib 35 is provided at only one location on the holding wall 34, but it may be provided at multiple locations.
Further, since the transition stopper 10 has the peripheral wall 18 provided around the entire circumference of the bottom wall 11, when the top cover B is closed after opening, the transfer stopper 10 may move downward compared to before opening. , without impairing the closure of the spout. Furthermore, since the peripheral wall 18 is provided around the entire circumference of the bottom wall 11, it suppresses the content liquid from entering the space between the transfer stopper 10 and the top lid B.

In this embodiment, the hinge cap is attached to the container body D by plugging, but it may also be attached by screwing.
Further, although the thin weakened portion 8 has the same thickness on the front side as on the hinge C side, it may be made thinner on the front side than on the hinge C side so that it is easier to break.

Next, a second embodiment in which the transition stopper 10 of the cap body A is changed will be described.
Hereinafter, the same components as those in the first embodiment will be denoted by the same reference numerals, only different components will be denoted by different symbols, and the differences will be mainly explained.

As shown in FIG. 6, Aa is a cap body attached to the container body D, and B is an upper lid that connects the cap body Aa with a hinge C to open and close.
The cap body Aa includes a partition 5 that seals the mouth 1 of the container body D, a spout cylinder 6 erected from the upper surface of the partition 5, and a spout 1 attached to the mouth 1, with the partition 5 formed inside. It is composed of a mounting section 7.

The partition wall 5 is provided with a transition stopper 50 defined by a breakable thin weakened portion 8 on the inner peripheral side of the spout tube 6 in order to open the spout during use.
The transition stopper 50 includes a bottom wall 51 connected to the partition wall 5 via the thin weakened portion 8. On the upper surface of the bottom wall 51, a substantially cylindrical pulling portion 12 is provided upright on the front side, and the hinge C side A holding wall 13 is provided upright along the inside of the thin weakened portion 8 .
In this embodiment, the bottom wall 51 is an inclined surface that slopes downward from the front side to the hinge C side, but the bottom wall 51 may be flat as in the first embodiment.

A tongue piece 59 is vertically provided on the lower surface of the bottom wall 51 along the thin weakened portion 8 from the hinge C side.
The outer peripheral surface 59c of the tongue piece 59 on the hinge C side curves outward so that the tongue piece 59 slides on the fractured surface of the thin weakened portion 8 when opening and closing the top lid B after opening, and accordingly, the inner peripheral surface 59b Also, the hinge C side is curved outward.
The tip 59a of the tongue 59 on the side of the hinge C is formed to be the longest, and the tongue piece 59 is inclined so that the length gradually becomes shorter toward the front side from both sides of the tip 59a.

Next, the effects of this embodiment will be explained.
In the transition plug 50 of this embodiment, the bottom wall 51 is inclined downward from the front side toward the hinge C side, so that the content liquid adhering to the bottom wall 51 is more easily transferred to the tongue piece 59 than in the first embodiment. This makes it easier for the water to flow downward.

In order to stir the content liquid, when the container main body D is shaken up and down with the lid closed, as in the first embodiment, the transition stopper 50 attached to the top lid B is moved to the lower surface of the bottom wall 51 and the tongue piece 59. However, since the lower surface of the bottom wall 51 slopes downward from the front side to the hinge C side, some of the liquid remaining on the lower surface of the bottom wall 51 is absorbed by the tongue piece 59. It flows down into the container body D along the inner circumferential surface 59b.
Further, since the tongue piece 59 is curved outward on the hinge C side, when the upper lid B is opened, the outer circumferential surface 59c of the tongue piece 59 comes into sliding contact with the fractured surface of the thin weakened portion 8, so that the tongue piece 59 is curved outward. The content liquid adhering to the outer circumferential surface 59c of 59 can be wiped off into the container body D.
Other effects are the same as in the first embodiment.

The hinge cap of the present invention allows the container body to be shaken before use to stir the contents, so that even if the contents adhere to the bottom surface of the transfer stopper, when the top lid is opened, it will stick to the bottom surface of the transfer stopper. Since the liquid content can be prevented from dripping into the top lid and outside of the container, it can be applied to a wide range of applications as a hinge cap for containers containing liquid content that needs to be stirred.
