Description

  The present invention relates to a spout attached to the mouth of a container, and is intended to easily determine whether the container has been tampered with visually.

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, this kind of pouring tap is fixed by fitting the annular groove of the base constituting the pouring tap into the mouth of the container (such as an undercut that links the concave and convex portions to prevent them from coming off. Engagement caps are applied), the cap is usually only screwed into the peripheral wall of the base, e.g. if only the cap is removed before the container is opened, The current situation is that there is no way to check whether this is the case.

  An object of the present invention is to propose a novel pouring tap that can be easily visually confirmed whether or not the cap has been illegally removed.

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 engaging the outer wall of the annular peripheral wall,
The base is provided with an annular body having at least one weakened portion (a thin-walled portion or a notched portion is applied) and surrounding the outer cylinder with a gap between them. It is provided with a bridge that can be torn apart at multiple locations.
The spigot is characterized in that the cap is provided with a locking member that enters the gap and is linked to the annular body so as not to be detached, and pulls up the annular body by opening the container to cut the weakened portion.

  The cap provided in the spout tap 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, It is preferable to use a ring that is reversibly connected via a hinge at the lower end.

  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 the cap is turned around to remove the cap, the annular body is pulled up along with the upward movement of the cap, thereby cutting the weakened portion, so it is confirmed at a glance whether the cap has been removed. can do.

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.

  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. They are fitted in a state where they are prevented from coming off by an engaging means such as an undercut (a projecting part and a projecting part engage with each other).

  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 pouring 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 integrally connected to the edge of the top wall 4a.

  Reference numeral 5 denotes an annular body that surrounds the outer cylinder 1b with a gap t at the lower end of the outer cylinder 1b. The annular body 5 is provided with at least one weakened portion 5a narrowly formed by the notch C and a recess 5b that partially thins the annular body 5 together with the weakened portion 5a. A claw portion 5c is formed at the upper end portion. The concave portion 5b can be provided on both sides including the weakened portion 5a.

  Reference numeral 6 denotes a bridge that integrally connects the annular body 5 and the outer cylinder 1b at six locations around it (see FIG. 2). The bridge 6 is made of a thin piece and can be easily torn with a small force.

  Reference numeral 7 denotes a locking member that is integrally provided at the lower end of the cap 4 and enters the gap t. A cylindrical body or a plurality of tongue pieces having the same shape as the peripheral wall 4 a of the cap 4 is applied to the locking member 7, and a claw portion that is linked to the claw portion 5 c of the annular body 5 so as not to be detached can be provided on its outer wall. 7a is provided.

  When the cap 4 is rotated to remove the cap 4 from the annular peripheral wall 2, the cap 4 moves upward. At this time, the claw portion 7 a is moved to the claw portion 5 c of the annular body 5. Since they are linked, the annular body 5 is also pulled up in accordance with the movement of the cap 4, and the weakened portion 5a is broken accordingly.

  When the weakened portion 5a of the annular body 5 is broken even before the container is opened, safety can be improved since it can be seen at a glance that the cap 4 is artificially touched.

  Although the annular body 5 is integrally connected to the outer cylinder 1b by the bridge 6, the bridge 6 is broken by grasping and pulling the broken portion of the annular body 5, and the annular body 5 can be easily removed.

  FIG. 3 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 reversibly connecting the ring 8 to the peripheral wall 4b. Reference numeral 10 denotes a captive connection between the peripheral wall 4b of the cap 4 and the ring 8. The bridge (thin wall piece) 11 is inserted into a concave portion 11b (two convex portions provided with a concave portion therebetween) having a convex portion 11a provided integrally with the peripheral wall 4b at the upper end of the ring 8. It is a detent that prevents rotation with respect to the ring 8.

  Normally, the spout is firmly fitted to the mouth of the container, and cannot be easily separated even if it is attempted to remove the spout from the container in order to separate and collect. When the cap 4 having the structure shown in FIG. 3 is detached from the annular peripheral wall 2, a force is applied in a direction to separate the cap 4 and the ring 8 from each other, whereby the bridge 10 is broken and the hinge 9 is shown in FIG. As shown in FIG. 5, it can be inverted as shown in FIG. 5, and it is attached again to the annular peripheral wall 2, hooked on the ring 8 and pulled upward to easily remove the spout. There is an advantage that an improvement in the collection rate in the separate collection can be expected.

  The hinge 9 can be constituted by a belt-like body, and the ring 8 can be easily reversed by providing a slit e (see FIG. 3) on the hinge 9 or the peripheral wall 4b of the cap 4 along the width end. It becomes.

  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. 4), whereby the peripheral wall 4b and the ring 8 can be easily separated. A bridge 13 similar to the bridge 10 can be provided at the position of 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. 3 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 projection 11 a is provided on the peripheral wall 4 b and the recess 11 b is provided on the ring 8. However, the recess may be provided on the peripheral wall 4 b and the projection 11 a may be provided on the ring 8. 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.

  It is possible to provide a spout that can be grasped at a glance whether unauthorized opening has been performed.
