Description

[Detailed description of the invention] container lid The present invention is particularly designed so that when the contents are removed and replaced, it remains as evidence. This invention relates to a pilfer-proof type container lid.

Pilfer-proof lids are well known, but their purpose is to ensure that the container to which they are applied The purpose is to provide visual evidence of whether or not it has been touched for some reason. Pilfer Blue fi is made of gold ffi or synthetic resin material, but the metal type is better. It is widely used. One well-known type is e.g. lead-tin alloy or shrink composite. It is equipped with a cap or sleeve made of resin.

Other well-known types are metal tacks to the bottom abutting by a gapped brittle bridge. In the case of synthetic resin, the key is pre-screwed. capping material and a protective or pilfer-proof ring. Therefore, the lid When the lid is used on a container, a protective ring is required to prevent rotation of the axis to remove the lid from the container. It is deformed or contracted below the support shelf on the container. The lid is rotated and removed from the container. The bridge will then be destroyed, indicating that the container has been opened.

In the alcoholic beverage industry, non-refillable installations are used to secure alcohol containers with fittings. It has become common to have them used.

Such installations allow the device to dispense liquid from the container, but the container cannot be refilled. It is equipped with a one-way valve that cannot be used.

Thus, when applying a container filled with alcohol with a non-refillable fitting, , the contents of the container cannot be mixed or diluted. kana The well-known non-refillable fitting is described in British Patent Publication Nos. 1 and 17. There is a tool to install No. 8,237 "Lylatum". For this installation, the fitting is inside the neck of the container. The pulp body is in close contact, the flange is attached to the annular shoulder, that is, the neck of the container, and the inside Consists of a screw spout through which the flavor is poured and the lid screwed on has been done. This installation requires a flange that goes over the container shoulder and It is held on the container by a barrel that fits into an annular opening in the lower neck. above pill Fur-proof lids are usually of the capsule type mentioned above, and the drawback is that The lid application step requires subsequent steps.

The present invention relates to an improved pilfer-proof lid, the primary purpose of which is to ensure that it is not refillable. A possible installation consists in providing a lid that can be used in conjunction with the fixture.

The container lid according to the present invention is a cap that is connected to the container or its attached member with a screw τ. an annular frangible ring rotatably engaged with the cap; and an annular frangible ring rotatably engaged with the cap; The ring is provided on the attached member and the fragile ring is prevented from being broken by rotation of the cap. It has the means to trigger it.

The screw cap may consist of one or two components. Two configurations Components include the container or its accessories, such as non-refillable attachment screws on the device. an inner screw thread member that is threadedly attached to the inner cap member; This is an outer cap member that can be rotated in the direction of loosening the cap. With this configuration, the outer cap is, for example, an inner rib or groove that engages an outer groove or rib formed on the inner cap. I/z with the following. The engagement attachment of these cap members is the outer camp part. The inner cap member may be provided with an outward protrusion or shoulder that can press the material into place. .

The annular frangible ring is separate from the cap member and can be forcefully connected to it, allowing two or more The upper weak point (e.g. thinner) is provided with a wall. This ring is formed on the camp member. The cap member is connected to the cap member by engaging with a rib extending in a radial shape.

When the cap is used on a container, the rotational movement of this interlocking rib cap is It is arranged so as to be transmitted to the ring. The cap member is connected to the inner cap and outer cap. If the outer cap is provided with an engaging rib, the engaging rib is appropriately formed on the outer cap.

Breaking of the frangible ring can be accomplished in a variety of ways. For example, one or more rings An inward protrusion or cam-like protrusion is provided. And correspondingly, the neck of the container That is, the mounting therein provides the same projection outwardly as above. If you do it like this When the cap is loosened, it becomes fragile. The ring rotates in the direction of loosening, and one or more The protrusions collide with one or more protrusions on the container and further damage will destroy the ring.

The destruction of the ring thus provides visual evidence that the cap has been loosened. or, First, a frangible ring is formed into an oval shape, deformed, placed on a container, and placed under tension. If you hold it on the container, when you loosen the cap, this ring will form an oval shape. It is also possible to make it so that it breaks.

Hereinafter, the configuration of the present invention will be explained in detail. First, the fragile ring is attached to the neck of the container, i.e. The inset fitting is placed on top of the fixture and the screw gap is screwed into it. Ru. Screwing the screw cap all the way to the bottom will remove the screw cap and the fragile lid. The ring is rotatable (connected), so if you subsequently try to turn the cap, The circular ring is destroyed. When using inner and outer caps, attach the inner cap to the container. That is, to install, after screwing into the tool, the outer cap is placed on the inner cap and pressed. So Therefore, the bottom edge of the outer cap fits into the bottom edge of the inner cap, and the outer cap and fragile link The rings are rotatably engaged.

Brief description of the drawing Embodiments of the present invention will be described based on the drawings.

FIG. 1 is an exploded perspective view showing the lid and non-refillable fitting according to the present invention.

Figure 2 is a cross-sectional view of the lid that covers the non-refillable attachment in the neck of the container. Ru.

FIG. 3 is a partially cutaway front view of the outer cap.

FIG. 4 is a partially cutaway front view of the inner gap.

FIG. 5 is a plan view of the frangible ring.

First, as shown in FIG. It consists of 3 rings. The lid is detailed in British Patent Publication No. 1,178,237. The installation is the same as the general structure but has been modified as described below using tool 4. use

It is a thousand-round top that is independent of the cart 11. There are grips on the outer surface of the skirt 11. A series of radially extending ribs] 3 are formed on the knurling 12 and the inner surface. has been done. The inner wall of the skirt 11 also has an annular shelf 14. bottom of skirt 11 There is a ring part]5 which is thinner than the thickness of the skirt 11, and this ring part 15 is A series of equally spaced ribs 16 are formed on the outer surface side.

The inner cap 2 shown in FIG. have. The outer surface of this skirt 21 engages with the rib 13 of the outer cap 1. A series of mating outwardly extending ribs 22 are formed. Inner cap 2 has a strip on the inside. It forms a screw thread 23, and also has a flexible section extending outward below the rib 22. It has an arched edge 24.

In FIG. It is an annular thousand-round shape extending for 1 minute.

The inner surface of the wall 31 is formed with equally spaced axially extending ribs 32. fruit As shown in the example, the ribs 32 are in two separate series, with each series The length of the wall 31 is approximately ]/4 of the inner periphery of the wall 31. The thousand-round body 30 is diametrically It has two generally triangular inwardly extending protrusions 33 located opposite to each other. each The thousand-round body 30 is interrupted at a place where the protrusions 33 are immediately adjacent to each other, which will be described later. The wall 31 is made thin so that the ring 3 breaks down, and two weak points are placed diametrically opposite each other. A portion 34 is formed.

As shown in the examples, the container lid of the present invention has a non-refillable attachment when used in conjunction with device 4. It is used. This mounting fixture 4 is shown in British Patent Publication No. 1,178,237. substantially the same as that shown in the figure, except that it has four outwardly extending protrusions 40. They are different. This projection 40 mates with the projection 33 of the ring 3.

For mounting, the fixture 4 is provided with an upper screw 42 that is based on an annular shoulder 43. It has a valve body 4I. Furthermore, the shoulder portion 43 is fitted with a mounting tool. It mates with an outwardly extending flange 44 over the edge of the container neck.

The lid is mounted on the neck of the container 50 as shown in FIG.

As shown in the figure, the sealing material 51 is placed on the spout at the neck of the container, and the attachment is performed using a fitting. 4. Fit the valve body 41 (only its outline is shown in Figure 2) into the neck of the container. Place the flange 44 on the sealant 51 to cover the spout of the container. There is. Attachment 4 is fixed to the container by means of known coupling members.

FIG. 2 shows two different coupling members. The left side shows a metal coupling member 52. and a deformed shape that can be locked to the flange 53 and the four annular portions 55 formed on the neck of the container. The mounting tool 4 is fixed by providing the circumferential portion 54 at a proper location. Also, the right side has a synthetic resin type connection. A mating member 56 is shown, with an inward flange 57 overlying said flange 44 and the neck of the container. An annular web 58 that engages with the lower part of the bead 59 formed on the part is provided at an appropriate location. There is.

The ring 3 is attached to the coupling member 52 or 56 through the upper screw thread of the tool 4. It is arranged on the flange 53 or 57.

Ring 3 preferably has protrusion 33 abutting protrusion 40 for reasons described below. Rotate until. When the inner cap 2 is screwed in, the sealant installed on the inner cap 2 The mounting material 6o is pressed against the upper part 42 of the tool 4. Push the outer cap 1 vertically downward. and fit onto the inner cap 2. At this time, the lip formed on the inner surface of the outer cap 1 The ribs 13 engage with ribs 22 formed on the outer surface of the inner cap 2. Also, outside When the cap 1 is pushed downward, the shelf 14 of the outer cap 1 deforms the arched edge 24. Beyond this, the shelf 14 and edge 24 are locked. In this way, the shelf 14 and the edge 24 are locked together. Therefore, it is not possible to remove the outer cap 1 from the inner cap 2 after this.

The outer cap 1 is pushed downward and slides onto the ribs 22 of the inner cap 2 to reach its bottom. The ribs 16 formed at the bottom of the outer camp 1 are placed on the wall 31 of the ring 3. It meshes with the formed rib 32.

Therefore, the outer cap 1 is held by hand and rotated G counterclockwise. outside cap Since the rib 13 of the inner cap 2 is engaged with the rib 13 of the outer cap 1, When rotated, the inner cap 2 also rotates at the same time. Also, the rib 16 of the outer cap 1 and the rib Ring: Since the ribs 32 are engaged, the rotation of the outer cap 1 rotates the ring 3. let When the ring 3 rotates, the attachment is caused by the protrusion 40 of the tool 4 and the protrusion 33 of the ring 3. collide. Furthermore, when the outer cap 1 is rotated to open it, the protrusions 33 and 40 is pressed and at least one of the weak parts 34 is destroyed. (As mentioned above, the protrusion 33 If the projections 33 and 40 are in contact with each other, the rib 16 is pressed by the projections 33 and 40. There is almost no possibility that the ribs 32 will disengage. ) then remove ring 3 The lid can then be opened in the normal way. If ring 3 is destroyed or removed, This indicates that the lid has been opened beforehand.

Various modifications of the structure of the ring 3 are possible. For example, the protrusion 33 collides with the protrusion 40. After that, when a cam action is performed such that the protrusion 40 rides on the curved surface of the protrusion 33, The ring 3 is deformed and stretched and finally breaks. Also, deform ring 3. By opening the lid, a pressure is created and this pressure causes the weak part 34 to break. For installation, the protrusions on each of the tool 4 and the ring 3 are shaped so that the ring 3 is destroyed by the transmission. You can do it.

In a preferred embodiment, the ring 3 is ejected from the container during breaking. This has seeds There are many methods. For example, the ring may be formed into an ellipse or deformed to one side. do. In this way, the ring is placed on the container, and by applying pressure to the ring, the container is removed. Or the attachment that comes with it is that the protrusions of the earth hold the ring in a circular shape. Therefore, Upon destruction, the ring is repelled from the container.

The ring may also be attached to the neck of the container or its attached fittings under pressure. A finger-like protrusion extending radially inward may be provided.

In the above embodiment, the ring 3 has two weakened portions 34 diametrically opposed to each other. However, the number is not limited as long as it is effective in destroying ring 3. Similarly, containers or In addition, the number of protrusions and the spacing between the protrusions for abutment are not limited either. In addition, The ribs 32 are preferably two separate series of ribs as shown. The number of series 32 and the number of weak parts 34 are the same, and more preferably the number of series of ribs 32 is the same. The length of each series shall not be more than half the length of the arc between weak points.

By doing this, for example, if four weak parts 34 are provided, the rib 32 of the ring 3 The length of each series is preferably less than or equal to ⅛ of the inner circumference of wall 31. basic Typically, each series of ribs 32 is comprised of a single rib. the important thing is Each series of ribs 32 is aligned in the direction in which the lid is opened (counterclockwise in Figure 5). It is located in front of the adjacent weak point.

Therefore, even if you rotate the cap to open it, the ring part that has a weak part will not be active. Not rotated.

All components of the container lid of the present invention are made of polyethylene, for example.

Appropriately formed from synthetic resin materials such as polystyrene, related to synthetic resin and glass containers used. In this example, the lid consists of two parts: an outer cap and an inner cap. However, if the lid is made of one part, the fragile ring can be replaced with a high-density pot. Molded from a relatively soft material such as polyethylene. Therefore, the lid is closed In between, the ribs on the lid can ride over the ribs formed on the ring. This is the cover This allows the ribs of the ring to be appropriately sloped. Therefore , the rib of the opening lid that closes the lid instead of opening it must go over the rib of the ring. Can be done. For example, British Patent Publication No. 7900354 describes the ribs of the lid or ring. It is good to have a shape like this.

The first effect of the present invention is that the non-refillable attachment device is attached to the pilfer-proof lid of the present invention. can be combined and all parts can be set in the container in one operation. It's all about what you can do.

All these parts are shown in FIGS. 1 and 2, respectively: outer cap, inner cap, 2. Ring 3. Attachment is by fittings 4 and coupling members 52 and 56. These are sheathing materials 5] A liquid-filled container 504 is used. The connecting member is gold. If the type is 52, another operation is required to fit the coupling member onto the annular fourth part 50. However, if the connecting member is a synthetic resin type 56, push the outer cap 1 downward. The annular web 58 is set under the bead 59 by pressure.
