JP5467945B2 - Pouring tap and stopper plugging and mounting method - Google Patents

Description

  The present invention relates to a pouring plug suitable for being attached to the mouth and neck of a container for pouring the contents by tilting the container, and a plugging and mounting method for the pouring plug. It is intended to achieve simple fixation and easy removal.

  Containers for seasoning ingredients such as soy sauce and dressing are equipped with virgin-type pouring taps that tear open the obstruction wall by pull ring and open the contents in the container. In the meantime, a screw-in type cap or an undercut type cap is adapted to the spout and the container is held in a sealed state (for example, see Patent Document 1).

  Such pouring taps are usually provided with an annular groove at the lower end of the pouring tap, and are attached by fitting the annular groove to the tip of the mouth and neck of the container by means of a stopper with a pushing force applied. Although the spout is fixed, it is inevitable that the peripheral wall of the fitting will be deformed when plugging, so a gap is formed between the outer wall of the neck and neck and the inner wall of the spout In such a case, while the sealing performance is deteriorated, when the spout is firmly fitted to the mouth and neck of the container, the spout is not easily removed when the container is disposed of, and separation and collection are not possible. It was difficult to do.

It is an external appearance perspective view of the principal part of the pouring tap shown in FIG. It is the figure which showed other embodiment of the pouring tap according to this invention in the cross section.

Hereinafter, the present invention will be described more specifically with reference to the drawings.
1 and 2 are views showing an embodiment of a spout according to the present invention as viewed from the side, FIG. 1 is a view showing a state before being plugged, and FIG. It is the figure which showed the state which closed the cover (The mouth-and-neck part of a container is not shown in figure).

  Reference numeral 1 in the figure denotes a base cap. The base cap 1 is integrally connected to a cylindrical cap body 1a that is directly undercut fitted to the mouth and neck of the container, and an upper edge portion of the cap body 1a via a weakened portion h. It is comprised from the annular body 1b which has an internal diameter substantially equivalent to a diameter. Here, as the weakening portion h, a thin connection piece may be provided over the entire circumference, or a plurality of thin connection pieces may be provided at intervals.

The cap body 1a includes a pouring cylinder 1a ₂ standing on the top wall 1a ₁ to form a content pouring path, and a concentric double-arranged inner cylinder 1a ₃ suspended from the lower surface of the top wall 1a ₁ . It has become the outer cylinder 1a _4, inner cylinder 1a _3, the mutual of the outer cylinder 1a ₄ is open downwardly, the annular groove m is formed to fit the mouth and neck of the container by capping.

2 is a circumferential groove provided in the upper part of the outer surface of the outer cylinder 1a ₄ (may be a locally provided recess), and 3 is a circumferential groove 2 provided in the upper part of the inner surface of the annular body 1b. A suitable convex part (which may be an annular one or a plurality of protrusions may be located), 4 is a lid that seals the extraction path of the base cap 1. The lid body 4 is composed of a peripheral wall 4a whose lower end surface is aligned with the upper end surface of the base cap 1, and a top plate 4b integrally connected to the upper portion of the peripheral wall 4a, and an upper edge of the outer cylinder 1a ₄ via a hinge 4c. and integrally linked to open and close the section, sealed contact with the pouring path inside the lower end of the pouring cylinder 1a ₂ of drooping cylinder 4d provided on the lower surface of the top plate 4b in closed position of the lid 4 To do.

5, sealing barrier which is integrally connected via the weakened portion h ₁ on the inner side of the pouring cylinder 1a _2, 6, a post which is provided on the edge portion of the sealing barrier 5, 7 in the pull ring provided at the upper end of the column 6 is there. By pulling the pull ring 7, the sealing barrier 5 is torn along the weakened portion h ₁ , and when the sealing barrier 5 is completely torn, an extraction path such as a circular shape is formed. Furthermore, 8 are a plurality of slits provided on at least the lower half of the outer cylinder 1a ₄ of the cap body 1a. As shown in FIG. 3, the slit 8 extends in the vertical direction along the axial center of the mouth-and-neck portion, and the lower end reaches the lower end of the outer cylinder 1 a ₄ and is open.

The spout according to the present invention is basically composed of a single member, and is in a state as shown in FIG. 1 before being attached to the mouth and neck of the container. In order to attach the pouring stopper to the mouth-and-neck portion of the container, first, the lid 4 is closed and the annular groove m of the cap body 1a is positioned at the distal end of the mouth-and-neck portion of the container. The annular body 1b may be pushed in the same direction as the cap body 1a at the same time as the annular groove m is fitted to the distal end of the container neck by applying a pressing force toward the base end of the container. Thereby, the weakened part h is cut | disconnected and this annular body 1b slides toward the base end of a mouth neck part, and as shown in FIG. 2, it fits to the outer surface of the cap main body 1a. Convex portions 3 of the annular body 1b, the cap will be fit and the annular member 1b to the circumferential groove 2 provided on the upper portion of the outer surface of the inner cylinder 1a ₄ functions as suppressing hoop spreading in the radial direction of the cap body 1a The main body 1a is firmly fixed to the mouth and neck of the container.

  Although the annular body 1b is in an engaged and positioned state by the circumferential groove 2 and the convex portion 3, the annular body 1b does not have a great thickness (the thickness is set to a minimum thickness that can function as a collar). And can be deformed relatively easily. For example, when the used container is discarded, the annular body 1b is pulled out from the cap body 1a with the lid 4 as a knob. Thus, the fitting force of the cap main body 1a to the mouth-and-neck portion is reduced, so that the spout can be removed relatively easily.

By providing a plurality of slits 8 as shown in FIG. 3 in at least the lower half of the outer cylinder 1a ₄ of the cap main body 1a, the fitting force of the cap main body 1a with respect to the mouth-and-neck portion is reduced, so Attachment and removal can be facilitated, but the same effect can be expected by locally thinning the part or making it thin over the entire circumference.

  The spout according to the present invention can be molded by applying an injection molding method using synthetic resin as a raw material. The cap body 1a and the annular body 1b are, for example, a soft material and a hard material by two-color molding. May be composed of different types of materials. This makes it possible to perform two-color molding by selecting a material according to applications such as heat resistance and non-heat resistance. Further, when performing the plugging, the lid 4 is closed.

  When the annular body 1b is pushed in, the convex part 3 is fitted and positioned by fitting into the circumferential groove 2, but when the pushing force of the annular body 1b is large, the lower end thereof is at the proximal end of the mouth-and-neck part. Since there is a concern that it will hit the neck ring that is formed, a protrusion is provided at the lower end of the cap body 1a, and when the annular body 1b slides, the protrusion abuts against the lower end of the annular body 1b for positioning. Good.

  FIG. 4 is a view showing another embodiment of the spout according to the present invention. A plurality of convex portions 9 are provided around the lower end of the inner side surface of the annular body 1b, or an annular convex portion 9 is provided, and a concave portion 10 linked to the convex portion 9 is provided at the lower end portion of the cap body 1a. The annular body 1b may be positioned with respect to the cap main body 1a. In such a structure, a step 11 having a hook margin t is formed on the top of the cap main body 1a. It is possible to make the portion 11 function as a stopper for preventing the annular body 1b from being removed, and there is a slight gap between the inner surface of the annular body 1b and the outer surface of the cap body 1a between the step portion 11 and the recess 10. Since t ′ is formed, there is an advantage that the annular body 1b can be easily removed when the container is discarded.

  In the present invention, an example in which the sealing barrier 5 is torn off by pulling the pull ring 7 to form a pouring path is shown as an example. However, the present invention is not limited to the illustrated one as long as unauthorized opening can be prevented.

  It is possible to provide a pouring stopper that can be securely fixed at the mouth-neck portion of the container and can be easily removed when the container is discarded, and a plugging and mounting method for the pouring stopper.
