Description

  The present invention relates to a container stopper.

As this kind of container, a breakable partition plate is laid horizontally inside the stopper tube that can be fitted to the mouth and neck of the container, and a ring-shaped finger hook is provided from the upper end of the support piece that stands up from the rear part of the partition plate. What protruded forward is known (patent document 1).
JP-A-2005-112386

    In the container of the prior art, the partition plate is broken by pulling a finger on the finger hanger.At this time, when the finger is put on the ring hole and before the ring is pulled up, the force is applied to the finger hanger. The ring hole may slip off. In order to prevent the finger from slipping from the finger hanger, it is effective to provide a rib for preventing slipping.

  Here, the place where the finger and the finger hanging tool come into strong contact with each other is the inner surface of the finger hanging tool. Therefore, if a rib for preventing slip is attached, it is attached to the inner surface of the ring hole of the finger hanging tool.

    However, this type of inner plug is generally molded with a synthetic resin material, and there are many technical restrictions to provide a rib on the inner surface of the ring hole. In other words, the first mold part that forms the inner surface of the ring hole and the second mold part that forms the outer side of the finger hook are required only by molding the finger hook part. If it is formed, there is a risk that the first mold part may be pulled out. That is, if the rib is large to some extent, the mold part cannot be extracted normally, and conversely, if it is a small rib that allows easy extraction of the mold, the effect of preventing slipping is small.

    Therefore, the present invention provides a container for a container that can be easily formed and can be reliably unplugged by attaching a rib to a rotating plate that is folded back to the inner surface of the finger hook instead of attaching a rib to the inner surface of the finger hook of the inner plug. The purpose is to provide a plug.

The first means attaches to the mouth-and-neck portion of the container, in which a substantially ring-shaped finger hook 16 is attached to a support piece 14 that stands up from a part of a breakable partition plate 10 that is laid horizontally inside the plug tube 2. In the inner plug for
A part in the circumferential direction of the substantially ring-shaped finger hook 16 is used as a finger locking part 20 having a certain width in the hole axial direction C1 of the ring hole 18, and both ends 20a, 20b of the finger locking part 20 in the hole axial direction are provided. The rotating plate 24 that can be turned back to the hole edge surface 18a side of the ring hole in the out-of-plane direction C of the ring opening surface S is projected from one of them through the bent portion 22,
An anti-slip rib 26 is formed on the outer surface of the rotating plate 24 so as to be positioned inside the ring hole in the folded state.

  In this means, instead of providing a rib at the hole edge of the finger hanger, it has been proposed to attach to the finger hanger a rotating plate with a rib that can be folded back inside the ring hole.

  The “finger hanger” is a means for breaking a partition plate by putting a finger on a ring hole and pulling it up. The phrase “substantially ring-shaped” means that the ring itself includes a C-shape as shown in FIG. In that case, a pair of adjacent support pieces may be erected from one side of the partition plate, and these support pieces may be connected to both ends of the C-shaped finger hook. In the preferred illustrated example, the finger hook protrudes from the tip of the support piece in the horizontal direction, but it may protrude obliquely upward, for example.

  The “finger locking portion” is a portion for hooking and pulling a finger directly or indirectly via a rotating plate. The finger locking portion has a width in the hole axial direction and a length in the circumferential direction suitable for hooking a finger.

  The “rotating plate” protrudes to the side of the ring hole, that is, in the out-of-plane direction C of the ring opening surface S so that a rib can be easily formed at the time of molding. It is formed so that it can be folded back. The out-of-plane direction C is a direction that forms a certain angle with respect to the ring opening surface S. The arrow in the out-of-plane direction C shown in FIG. 1 is an example of the out-of-plane direction. The out-of-plane direction may be a direction perpendicular to the ring opening surface S (the hole axial direction C1 of the ring hole), but is inclined with respect to the hole axial direction C1 as long as it does not hinder the return to the ring hole edge side. It doesn't matter.

The second means includes a first means, and the rotating plate 24, both end portions 20a of the finger engaging portion 20, while as to protrude into the hole axis C ₁ from 20b, the rotary plate 24 The inner surface of the finger and the hole edge surface 18a of the finger locking portion 20 are formed in a flat shape that is gently continuous when viewed from the cut surface including the hole axis, and at least the rotating plate 24 and the finger hook 16 are integrally formed. is doing.

  This means proposes a rotating plate and an inner shape of the finger locking portion that facilitate the extraction of the inner mold part that forms the ring hole edge surface when molding the mold. The inner surface of the rotating plate and the inner surface of the finger locking portion can be formed substantially flush with each other.

Third means includes a second means, and the rotary plate 24 and the finger engaging portion 20 as viewed from Anajiku direction C ₁ formed in the same arcuate, rotating plate 24 is ring opening surface The rotating plate 24 and the finger hook 16 are made of an elastic material so that the state can be elastically reversed between the protruding state in the out-of-plane direction C and the overlapping state of the hole edge portion of the finger locking portion 20.

In this means, the rotating plate is provided so as to be elastically reversible, and the rotating plate automatically overlaps the inner surface of the ring hole when pushed in beyond the dead center position during the rotation. During this reversal operation, the rotating plate is viewed from the tip side (D _{1 to} D _{3 in} FIGS. 4A to 4C) in the positive arc state “(” to the linear state “|”. The arc state in the reverse direction “)” is sequentially transformed. The finger locking portion is formed to a length that can get over the dead center position. Even if it says an elastic material, it does not need to be an elastic body like rubber | gum, but polyethylene, PP, or a material which has elasticity comparable as these is sufficient.

The fourth means includes any one of the first means to the third means, and the rotating plate 24 is connected to the end portion 20a opposite to the partition plate 10 at both ends of the finger locking portion 20. Protruding from.

The fifth means includes any one of the first means to the fourth means, and the finger locking portion 20 is formed on the opposite side of the finger hanging tool 16 from the connection portion with the support piece 14. Yes.

    According to the invention relating to the first means, instead of attaching ribs to the hole edge surface 18a of the finger hanger 16, the rotating plate 24 protruding from the finger locking portion of the finger hanger is folded inwardly in the ring hole. Since the anti-slip ribs 26 are provided so as to be positioned at the positions, the ribs can be formed large.

    According to the second aspect of the invention, the rotating plate 24 protrudes from the one end portion of the finger locking portion 20 in the hole axial direction, and the inner surface of the rotating plate 24 and the hole edge of the finger locking portion 20. Since the surface 18a portion is formed into a flat shape that is gently continuous when viewed from the cut surface including the hole axis, it is easy to remove the die when molding the die.

  According to the third aspect of the invention, the rotating plate 24 elastically reverses between the protruding state of the ring opening surface in the out-of-plane direction C and the overlapping state of the hole edge portion of the finger locking portion 20. Easy to operate.

    According to the fourth aspect of the invention, the rotating plate 24 protrudes from the end 20a on the opposite side of the partition plate 10 out of the both ends of the finger locking portion 20, so that the partition plate is used for the unplugging operation. It does not get in the way.

  According to the fifth aspect of the invention, since the finger locking part 20 is formed on the opposite side of the finger hook 16 from the connecting portion with the support piece 14, it is easy to apply force to the finger locking part 20.

  1 to 3 show an inner stopper for a container according to a first embodiment of the present invention. First, heretofore known matters of the inside plug will be described.

  The inner plug hangs the mounting cylinder 6 from the outer surface of the plug cylinder 2 through the outward flange 4 so as to sandwich the mouth and neck of the container between the lower half of the plug cylinder 2 and the mounting cylinder. Provided. The upper end portion of the plug cylinder 2 is connected to the outer middle portion of the upper end large-diameter nozzle cylinder 8 via an inward flange. The lower end surface of the nozzle cylinder is closed with a partition plate 10, and a break line 12 is formed in the outer peripheral portion thereof. A support piece 14 is erected from the rear side of the partition line portion inside the fracture line, and a finger hook (pull ring) 16 protrudes upward and forward from the tip of the support piece. This finger hook has a ring hole 18 opened in the vertical direction. The inner plug can be integrally formed of a synthetic resin material.

  In the present invention, the rotating plate 24 protrudes upward and outward from the upper end portion 20 a of the finger locking portion 20, which is a part of the finger hook 16 in the circumferential direction, via the bent portion 20.

  The finger locking part 20 is located on the opposite side of the finger hanging tool 16 from the connection part with the support piece 14. In the example of illustration, the finger | toe latching | locking part 20 is top view circular arc shape which has the same curvature center as the other part of a finger hook. Even if it says the finger | toe latching | locking part 20, it is not necessary to set it as a structure (width, thickness, etc.) different from the other part of a finger hook.

  The rotating plate 24 has an inner surface that is substantially flush with the inner surface of the finger locking portion 20. When the rotating plate 24 is elastically inverted around the bent portion 22, these inner surfaces abut or have a slight gap. It is configured to maintain that state when facing each other. A plurality of lateral ribs 26 are attached to the outer surface of the rotating plate 24.

With respect to the above-described configuration, when the inner plug is molded, as schematically shown in FIG. 5, first of all the first and _second molds M ₁ and M ₂ for locking the finger hook 16 are the first mold M _1. Pull out. Then, the inner surface of the finger-hooking tool 16 is so flat, it is possible to extract the mold M ₁ smoothly. Now pulled out outside of the mold M _2, so the location where there is the mold M ₁ is empty office, that finger hook member and a finger engagement portion is bent inwardly, draw mold M ₂ it can.

  After molding, when the rotating plate is folded inward from the state of FIG. 1, it is reversed in the order shown in FIGS. 4 (A) to (C), and is securely placed inside the finger locking portion as shown in FIG. To fit. In this state, the inner plug is attached to the mouth and neck of the container. When opening the inner plug, if the finger is hooked on the finger locking portion and the rotating plate from the state of FIG. 3, the finger is firmly locked to the rib.
