Description

Detailed Description of the Invention (Industrial Field of Application) The present invention mainly relates to a synthetic resin bottle-sealing lid for sake, which is equipped with a metal canopy with an inner stopper that allows the sealing and unsealing operations to be performed reliably and safely. This relates to a bottle sealing lid made by combining a metal plate.

(Prior art) Many types of lids for alcoholic beverage bottles have already been proposed and put into practical use, but as is well known, these types are made of corks or polyethylene resin instead. The cylindrical part of the sealing lid is designed to fit the inner stopper into the mouth of the bottle, and a cap-shaped sealing lid made of a thin metal plate such as aluminum on the outside to fit over the neck of the bottle and tighten the seal. The seal is opened by tearing off the joint provided between the diagonal cutting line and the part forming the tab, so if you are not careful when picking and tearing this tab, you will end up getting your fingertips cut by the cut. In addition, if the incision line is not sufficiently formed and the force applied to the gripping piece is not appropriate, the gripping piece may be torn to pieces from the body of the sealing lid without being opened firmly. This poses a problem, such as making it useless and making it difficult to open.

Therefore, as one solution to this problem, a sealing lid with a puffer for opening has been proposed.

However, this type of Monoke tag requires extra material to form, and depending on the shape of the tab, it can be as dangerous as the American one, making it useless, and therefore there is no way to make it safe. It becomes necessary to take additional measures such as forming links to make it easier for the fingertips to hang, and covering the curved part with synthetic resin, which not only increases the price but also reduces the production time. Inconveniences tend to occur in handling during packaging and sealing operations, and there are various problems.

(Object of the Invention) The present invention solves certain conventional problems, and forms only the canopy and the constricted sealing part from a thin metal plate, which are combined integrally with the stopper, and the stopper and the sealing cylinder part, that is, the opening part. The object of the present invention is to provide a sealing lid with a bottle stopper that is integrally formed of synthetic resin and configured so that sealing can be performed reliably and it can be operated safely when opening.

(Structure of the Invention) The present invention includes integrally forming a thin-walled sealing cylinder part of an appropriate length from the outer periphery of the flange of a bottle stopper made of synthetic resin, and extending the sealing cylinder part from the canopy of the synthetic resin bottle stopper. The outer surface up to the retracted position is covered with a thin metal plate, and the thin metal plate canopy and the sealing constriction ring are separated by spring tightening in a groove provided on the outer periphery of the bottle stopper, and each is integrated into one body. Attachment: A cutting line is carved in the body of the sealing cylinder at a suitable place from the lower end to the sealing ring so as to rise directly or inclined upwards from the lower end of the sealing cylinder, and at the lower end along the cutting line. A gripping operation part is formed, and a required number of cutting lines are carved at key points of the sealing crimping ring to form an fc, and the sealing cylinder is pulled up from the gripping operation part along the cut lines. A bottle with a combination structure in which the operating part is made of synthetic resin and the part that maintains the sealing function is made of a thin metal plate. It is a sealed lid with a stopper.

(Example) Below, the sealing lid of the present invention will be described in detail with reference to an example diagram.
The one shown in Figures and Figure 2 is a type of sealing lid with a bottle stopper that is opened by pulling the gripping piece of the sealing cylinder upward from the bottom end, and is made of a soft synthetic resin material such as polyethylene resin. Bottle stopper (2) and sealing cylinder (3) are integrally molded, and a thin metal plate (for example, an aluminum laminate plate) that covers the top surface of the bottle stopper (2) and is spring-tightened and fixed around the outer periphery of the brim (6). It consists of a sealing ring (11) made of a thin metal plate that connects with a canopy 101 made of plastic and is fitted and fixed to the sealing cylinder (3) to the position where it is tightened around the outer periphery of the bottle neck when capping.

As shown in the figure, the bottle stopper (2) has a shape in which the top plate side of the stopper (4) is open and has a suitable thickness and elasticity.
A groove (6) is carved on the outer periphery of the flange (6) at a position near the bottom, and a concave curved surface (7) is formed on the lower surface of the flange (5) so that it almost extends to the mouth end of the bottle. ) is formed around the base of the stopper (4), extends downward from the outer periphery of the collar (6), and is integrally molded as a thin-walled sealing cylinder (3) of the required length, and the concave curved surface (7)
A thin string-like protrusion (8
) is formed. And the fire lid (lO
) Another groove (9) for fixing the constriction ring (II) for sealing is carved in the lower position of the tightening groove (6). For a given bottle stopper (2), the canopy and the sealing constriction ring H are initially integrally molded from a highly malleable thin metal plate such as an aluminum plate (but not limited to this). Fit it onto the bottle stopper (2), wrap it in the groove +6) of the flange (5) and cut it, and fix the canopy (10) by wrapping the edge (10) in the groove (6). , sealing ring (llH is the groove (6) of the collar (5)
The upper edge and the middle part are tightened and fixed in the lower groove (9) of the collar.

In such a combination structure of a bottle stopper (2) and a metal covering part, and in which the sealing tube (3) is longer than the metal sealing constriction ring (I1), there is an operation part structure for opening the bottle. As shown in Fig. 2, the lower end of the sealing tube (3) has a width that is suitable for removing the bacteria, and it is connected to a portion o4 u4.
Cut lines 112) (112) (1) are carved parallel to the lower half of the inner side of the constriction ring II+!, so that the space between both cut lines (I2) becomes a gripping piece for opening, and the seal is sealed. One or more incision lines α4) are provided on the circumferential surface of the constriction ring UG in the vicinity of the extension of the gripping piece tea forming portion. In addition, the condensed ring L1
The cut line H1d provided in 1 may be attached at the time of forming the cap of the metal body.

The sealing lid of the present invention constructed as described above is treated in the same manner as the conventional sealing lid with an inner stopper, and as shown in Figure 4f; An annular ring provided on the outer periphery of the rear bottle neck W, K11, which is inserted into the bottle mouth and attached.

The internal force of the first grade is J: and the cut line +
At the 18th point according to 14), the equilibrium is broken at the cut line of the chair tag with φ1, and as a result, the seal caused by the constriction is released and the bottle becomes openable.

What is shown in FIG. 3 is another embodiment, in which a bottle stopper (2)
The sealing tube (3) and the sealing constriction ring tlll have the same basic combination structure as that of the previous embodiment, and in this sealing lid (IA), the gripping piece L131 provided on the sealing vJ+3) It is constructed in the same manner as the embodiment described above, and in this case, a knurled notch U+ slightly deeper in the axial direction is formed on the entire circumference of the sealing ring 1+5. It should be noted that the same reference numerals as in the previous embodiment are used to represent the parts having the same structure as those in the first embodiment.

According to the sealing lid (LA) having such a structure, during the sealing operation, it can be handled and processed in the same way as the above-mentioned one, and a reliable seal can be achieved. By pulling up, the cutting line 12) U is exposed to the urinary part t.
12) After tearing the lli, the sealing ring (when reaching the narrow sealing ring 16, the sealing ring 16 has a number of knurling notches 1151, so any one of them At the weakened part, the bottle loses its balance and breaks, releasing the seal and allowing the bottle to be opened.

In addition to the above-mentioned type in which the bottle is unsealed by pulling up the grip piece in a straight line, there is also a type of bottle stopper with the structure shown in the first embodiment as shown in Fig. 6 ( 2B) and a low-fixing metal plate canopy (■0) and sealing shrink @ surface and 7
The sealing cylinder (3B) of the bottle stopper (2B) is fitted with a gripping part (+6) along the 9J line upwards from the lower end near the periphery as shown in the figure. The sealing lid (IB) has a structure in which the metal plate part and the synthetic resin part are engraved with intermittent cut lines 11 west extending obliquely upward from the gripping part +17) to the crimping ring (IT). Even if i1■
Seal the bag in the same manner as in the first and second embodiments, and when opening the bag, pinch the gripping part (17) and pull it diagonally upward. By tearing the connecting portion 1+411Th) between the two, the sealing crimped ring portion is broken, and the seal can be broken and opened easily. Note that the cut shape of the cut line forming such a grip (1η) and the positional relationship of the connection between the VJ green end and the next cut line carved part are as shown in the diagram. However, when making a slight deviation in the vertical direction, or how to make a cut line for breaking the seal from the cut line end position to the seal e condensation position, use the gripping part 0η. How to attach a cutting line or perforation line (weakening line) that acts so that when a diagonally upward tearing force is applied to the sealing tube (3B) by pinching, the tightening force of the tightening ring part is weakened and then it is broken. That's fine.

Furthermore, a sealing tube (3c) like the sealing lid (10) shown in FIG.
), there are many notches in the axial direction (the river is carved all around the circumference, and at the lower end of the periphery there is one or more cuts indicating the opening for the broken seal, !l). This cutting row should be connected to the notch (14 valley part), and a cut line un of an appropriate length should be made upward from the lower edge of the sealing condensation ring (l la) part at the revised point. In the case of the sealing lid Qc) configured in this way, in order to open the seal after opening, press the fingertip from the appropriate cut 6 of the seal and cylinder reduction part (3c). By prying it open with a similar tool, it will be torn at the notched end, and this torn part will become a gripping piece, so by pulling the gripping piece upward strongly, you can tighten the ring (lla). The force acting on the section causes the nearby section line (section 191) to be torn upwards, resulting in the seal being broken.

Therefore, in the case of this lid, the position for breaking the seal is not specified, and the lid can be opened at any appropriate location around the lid.

In the center of the moon, the lid (ID) is placed on the moon F as shown in Figure 8.
A gripping piece (c) is cut out in the circumferential direction of the sealing cylinder (3D), and this gripping piece is used to secure the proximal edge Q of the sealing tube (3D).

By tearing the cocoon (2f) and the upward tension wi+, and pulling the turned-up part of the seal upward, the vJ Midorihin seal of the d-ring (llb) is tightened. /Ip Choto can be cut and sealed.

What has been described above is a part of the embodiments based on the spirit of the present invention, and these partial opening means may be combined. In addition, as shown in Fig. 9, there is a stopper (4') which is formed in an annular shape and fits into the mouth of the bottle.
It may also have a structure in which it is combined with a bottle stopper 12). Of course, it goes without saying that the above-mentioned method can be used for the sealing cylinder and the proofing ring.

In addition, if you make a 9-score line in the circumferential direction on the upper outer periphery of the sealing tube in advance, just at the part that is hidden by the constriction ring, you can attach the new sealing tube to this score line after sealing. By cutting it down, only the stopper with the fire lid f101 is cut off, and that part can be used as a bottle stopper.

(Effects of the Invention) According to the present invention, when sealing and reducing bottles, it can be handled in the same way as the conventional single @ sealing lid or stopper one sealing lid, and there is no problem at all. A crest made of a thin metal plate that is easily plastically deformed! The seal can be reliably sealed at the #3J'' 4. part, and the thin-walled synthetic resin tube part inside can be fixed, and when turning, the thin-walled synthetic resin tube part is sealed. The seal can be easily opened by pinching or pulling up the holding piece or similar part and tearing and breaking the sealing constriction ring made of metal along with the sealing tube, and this synthetic resin part It solves the problems of conventional products, such as being able to operate safely without damaging the fingertips because the package is opened by grasping the part made of a soft material, such as polyethylene resin, and is also as inexpensive as conventional products. It possesses advantages that conventional sealing lids do not have, such as being able to provide the following benefits, and its industrial effects are outstanding.
