Description

  The present invention relates to a spout suitable for being attached to the mouth of a container, and when discarding the container, the spout is removed from the mouth and the components of the container are collected for each of the same materials. With regard to the recovery, it is intended to further increase the recovery rate.

Containers for seasoning ingredients such as soy sauce and dressings 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).
Utility Model Registration No. 2548506 Specification

  By the way, in this type of container, the container main body part, the spout (inner stopper), and the cap are usually made of different materials. Individual collection and collection are important for effective use of resources. Especially, the base of the spout tap is firmly fitted to the mouth of the container in the annular groove that opens downward. As a result, it could not be removed easily and it was difficult to achieve separate collection.

As a prior art in this regard, an appropriate number of deep grooves are provided in the outer tube of the inner plug to be fitted to the container neck and neck, and the bottom of the groove is formed as a thin flexible part or a ruptured part. A holding cylinder that hangs down from the lower end of the threaded cap female screw cylinder through the outward flange-shaped top wall is fitted to the outer surface of the outer cylinder, while leaving a small number of easily breakable connectors on the outward flange-shaped top wall. There is known a container with an internal stopper that also serves as a nozzle, provided with engaging protrusions that are provided around the respective grooved surfaces and that come into contact with each other when the male screw cylinder is rotated in the tightening direction from each opposing surface of the groove (see, for example, Patent Document 1). However, since the container with a stopper has a relatively complicated structure, there is still room for improvement in manufacturing method for efficient production with high molding accuracy.

  An object of the present invention is to propose a spout that can be removed from the mouth of a container under a relatively simple operation when the container is discarded.

The present invention comprises a base having a concentric double arrangement of an inner cylinder and an outer cylinder, an annular groove opened downward between the inner cylinder and an outer cylinder, and a mouth portion of a container fitted into the annular groove and fixedly held. A pour-out that allows the contents in the container to be discharged by opening a pour-out path by tearing a closed wall that is provided inside the ring-shaped peripheral wall and a closed wall that is provided inside the ring-shaped peripheral wall. A spout provided with a tube and a cap having a storage space for covering the spout tube and removably engaged with the outer wall of the annular peripheral wall,
The lower end portion of the outer cylinder is provided with an annular body that surrounds the entire circumference of the outer cylinder, and between the annular body and the outer cylinder, a thin connecting piece that connects them at a plurality of locations is disposed.
Said annular body, the mouth of the container have a weakened section which divided along at least one portion of its rotation in the width direction when pulled out of the annular groove,
The cap includes a top wall located at the mouth end of the container, a peripheral wall integrally connected to the edge of the top wall and surrounding the mouth side wall of the container over the entire circumference, and a hinge at the lower end of the peripheral wall. The spout is characterized by comprising a ring that is connected in a reversible manner .

  Between the peripheral wall and the ring, they are connected to each other at a plurality of locations, and a bridge that can be broken by being separated from the annular body, and a convex part is inserted into the concave part to prevent rotation of the peripheral wall relative to the annular body. A detent can be provided.

  When a pulling force is applied to the spout, the outer cylinder will get over the convex part at the mouth of the container (protrusion for forming an undercut engagement in which the convex part and the convex part engage with each other and are prevented from coming off). At this time, the tensile force along the circumference of the annular body acts on the annular body and the annular body itself breaks from the weakened portion. Since the fitting force with respect to the mouth part of the tap becomes small, the removal of the pouring tap becomes easy.

Hereinafter, the present invention will be described more specifically with reference to the drawings.
1 to 5 are views showing an embodiment of a spout according to the present invention.

  Reference numeral 1 in the figure is the base of the spout. This base 1 has an inner cylinder 1a and an outer cylinder 1b arranged concentrically and forms an annular groove m opened downward between them. The mouth of the container is formed in the annular groove m. Fitting (undercut engagement in which the convex portion and the convex portion are engaged with each other to prevent detachment) is performed.

  Reference numeral 2 denotes an annular peripheral wall integrally provided on the upper portion of the base 1, and 3 denotes a pouring cylinder integrally disposed inside the annular peripheral wall 2 (the base 1, the annular peripheral wall 2, and the pouring cylinder 3 are arranged). All can also be called inner plugs). The pouring tube 3 is provided with a blocking wall 3a for closing the pouring path r, and the pulling wall 3a connected to the closing wall 3a is caused by tearing the blocking wall 3a along the planned breaking groove S. The outgoing route r can be opened.

  Reference numeral 4 denotes a cap that has a storage space that covers the dispensing cylinder 3 and is detachably engaged with a screw portion provided on the outer wall of the annular peripheral wall 2. The cap 4 includes a top wall 4a and a peripheral wall 4b that is integrally connected to the edge of the top wall 4a.

  Reference numeral 5 denotes an annular body that is provided at the lower end of the outer cylinder 1b and surrounds the entire circumference of the outer cylinder 1b. The annular body 5 functions as a ridge that suppresses, to some extent, the diameter of the outer cylinder 1b from expanding outwardly when the spout is fitted to the mouth of the container. Reference numeral 6 denotes a thin connection piece disposed between the annular body 5 and the outer cylinder 1b. The thin connecting piece 6 is used to connect the annular body 5 and the outer cylinder 1b at the lower end portion thereof, and is provided at a plurality of locations around the space. This thin connecting piece 6 is set to a thickness that can be separated by pulling up the annular body 5 upward or downward, and can be bent so that its central portion is convex upward. .

  Reference numeral 7 denotes a weakened portion provided in the annular body 5 (see FIGS. 1 and 3). The weakened portion 7 can be formed by a thinned portion that is thinned by a notch or the like, and the diameter of the outer cylinder 1b is increased (when the convex portion 1b 'of the outer cylinder 1b gets over the convex portion t of the mouth, 5) when a large tensile force is applied to the annular body 5 (when a pulling force is applied to remove the spout from the mouth), the annular body 5 is moved in the width direction (in the drawing). Divide vertically).

  When the annular body 5 is divided at the weakened portion 7, the pouring tap having such a configuration is such that the outer cylinder 1 b easily expands outward and the fitting force with respect to the mouth portion is weakened. Can be removed.

FIG. 6 is an external perspective view showing another embodiment of the spout according to the present invention.
Reference numeral 8 in the figure denotes a ring provided at the lower end of the peripheral wall 4b of the cap 4. Reference numeral 9 denotes a hinge for connecting the ring 8 to the peripheral wall 4b so that the ring 8 can be reversed, and a bridge for connecting the peripheral wall 4b and the ring 8 of the cap 4 so as to be separated. (Thin-walled piece) 11 is a ring of the cap 4 that is inserted into a concave portion 11b (two convex portions are formed between the concave portions) provided with a convex portion 11a integrally provided on the peripheral wall 4b at the upper end of the ring 8. 8 is a detent that prevents rotation with respect to 8.

  When the cap 4 having such a configuration is detached from the annular peripheral wall 2, the bridge 10 is broken by applying a force in a direction to separate the cap 4 and the ring 8 from each other, and the ring 8 is inverted as shown in FIG. In this inverted state, as shown in FIG. 8, it is attached again to the annular peripheral wall 2, a finger is hooked on the ring 8 and pulled upward to easily remove the spout plug.

  The hinge 9 can be constituted by a belt-like body, and the ring 8 can be easily reversed by providing a slit e on the ring 8 or the peripheral wall 4b of the cap 4 along the width end thereof (FIG. 6). reference).

  In addition, a finger-holding recess 12 can be provided at the upper end of the ring 8 at the opposite position where the hinge 9 is provided (see FIG. 7), whereby the peripheral wall 4b and the ring 8 can be easily separated. A bridge 13 similar to the bridge 10 can be provided in the recess 12. The bridge 13 may be a protrusion for hooking a finger, or the installation of the bridge 13 itself can be omitted. When the installation of the bridge 13 is omitted, only the recess 12 exists.

  In particular, the cap 4 shown in FIG. 6 can be molded as a single member by injection molding a synthetic resin, and there is no problem that the number of parts increases.

  As for the rotation stopper 11, the convex portion 11 a is provided on the peripheral wall 4 b and the concave portion 11 b is provided on the ring 8. However, the concave portion may be provided on the peripheral wall 4 b and the convex portion 11 a may be provided on the ring 8. Further, the convex portion 11a may be projected downward in addition to the type projecting outward in the radial direction of the peripheral wall 2, and may be appropriately changed according to the size and shape of the cap. Moreover, although the case where one weakening part 7 was provided was shown, it cannot be overemphasized that two or more can be provided.

  A pouring tap that can be easily separated and collected can be provided.
