Description

  The present invention relates to a lid with a pouring tube, and in particular, a pouring tube comprising a lid body having a bottomed cylindrical pouring tube and an upper lid, which is used by being attached to the mouth and neck of a container main body that contains an internal solution. It relates to a lid with a cover.

  As a lid used by attaching to the mouth and neck of the container body containing the internal solution, for example, it comprises a lid body and an upper lid. The lid body is provided with a bottomed cylindrical pouring tube, and is formed by a groove or a thin part. 2. Description of the Related Art A lid with a pour tube is known that has a planned opening portion in which a pour hole is formed by tearing a score composed of an easily breakable portion in a bottom plate portion of the pour tube (for example, see Patent Document 1).

In such a lid with a pouring tube, generally, the pulling ring provided integrally with the bottom plate portion of the pouring tube via a leg piece is pulled up to break and remove the planned opening portion along the score. Is supposed to form. Moreover, in such a lid with a pouring tube, the easiness of pouring when the inner solution is poured from the formed pouring hole through the pouring tube is improved, or the pouring amount can be adjusted.

  On the other hand, in the conventional lid with a pouring cylinder, the pull ring is accommodated inside the pouring cylinder, and the ring-shaped seal provided on the upper lid is brought into close contact with the inner surface of the tip of the pouring cylinder at a position close to the upper lid. For this reason, the dispensing cylinder is provided upright from the bottom plate portion at a considerable height. Therefore, when the inner solution is to be poured out by tilting the container, the width of the inner solution discharged from the dispensing hole increases along the arc-shaped inner circumferential surface when passing through the dispensing tube. In addition, when the flows collide with each other in an attempt to return from the expanded state, the liquid contents are less likely to be collected when being dispensed from the tip of the dispensing cylinder, and liquid scattering is likely to occur. Such a tendency of liquid dispersion becomes particularly prominent when the inclination of the container is increased and the amount of pouring is increased.For example, as shown in Patent Document 2, by simply projecting the beak-shaped portion at the tip peripheral portion of the pouring cylinder, It is difficult to suppress liquid scattering.

  The present invention effectively suppresses the occurrence of liquid scattering due to the inner solution discharged from the dispensing hole spreading along the inner peripheral surface of the dispensing cylinder when the container is tilted to dispense the inner solution. Thus, an object of the present invention is to provide a lid with a dispensing cylinder that can dispense the internal solution well from the dispensing cylinder.

  The present invention comprises a lid body and an upper lid that are attached to the mouth-neck portion of a container body. The lid body is provided with a pouring tube having a bottom plate portion, and is poured by breaking the easily breakable portion of the bottom plate portion. A lid with a dispensing cylinder having a planned opening portion in which an outlet hole is formed, wherein the planned opening portion has a radial width of the bottom plate portion between an inner edge and an outer edge of the dispensing cylinder. Provided on one side of the bottom plate portion along the inner peripheral surface of the extraction cylinder so that the inner diameter is 1/3 or less of the inner diameter, and the outer edge is close to the inner peripheral surface of the extraction cylinder. When the internal solution is poured out by opening the pouring hole, the container body is tilted so that one end of the pouring hole by the planned opening portion is on the lower side. The above-mentioned object is achieved by providing a lid with a protruding tube.

  According to the lid with the dispensing cylinder of the present invention, when the inner solution is poured by tilting the container body, the inner solution discharged from the dispensing hole spreads along the inner peripheral surface of the dispensing cylinder and is scattered. Can be effectively suppressed, and the inner solution can be poured out from the dispensing cylinder well.

In other words, in the lid with the dispensing tube, when the internal solution is poured out from the dispensing hole formed by breaking and removing along the score (easy break line) by pulling up the pull ring, it is poured out. In particular, when the amount of the liquid dispensed increases due to the inclination of the container, the width of the inner solution increases along the arcuate inner circumferential surface when passing through the dispensing cylinder, and flows to return from the expanded state. By colliding with each other, the liquid contents are less likely to be collected when being dispensed from the tip of the dispensing cylinder, and liquid scattering is likely to occur. In order to be able to effectively suppress the occurrence of such liquid scattering, the lid 10 with the extraction tube of the present embodiment is employed.
