Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This proposal relates to a lid plug with a breakable opening that is integrally molded from synthetic resin material.

0002

[Conventional technology]

A lid plug whose shape is obtained by removing the elastic guide piece 18 from the lid plug shown in FIG. 3, that is, the outside of the first top wall 2 A first peripheral wall 3 is provided vertically to be fitted from the periphery to the upper outer surface of the mouth and neck of the container body, and a first The central part of the top wall is formed into a peeling plate 6 by providing five thin broken lines around it, and a part of the outer periphery of the peeling plate is formed. A first top wall portion from which a protruding piece 8 with a finger ring 7 is erected and which further surrounds the above-mentioned breaking line. The spouting tube 9 is placed higher than the finger ring 7, and there is a space between it and the outer periphery of the first top wall. The short fitting tube 10 is inserted from the upper surface of the first top wall leaving a gap, and the plug body 1 and the above-mentioned A seal tube 12 that is watertightly fitted to the upper inner surface of the projecting tube 9 is inserted from the lower surface of the second top wall 13 and from a short distance. A lid in which a second peripheral wall 14 fitted to the outer surface of the fitting tube 10 is hung from the outer periphery of the second top wall. It has a plate 11, and a cover plate can be opened and closed at the rear of each of the first peripheral wall 3 and the second peripheral wall 14.

[Problem that the idea aims to solve]

In the conventional lid stopper mentioned above, when the lid is closed, the lid plate rotates around the hinge and the seal tube opens. It is provided to fit into the inner surface of the upper end of the spouting tube, but in order to make the fitting watertight. The outer diameter of the seal cylinder and the inner diameter of the upper part of the spout cylinder are approximately the same diameter, so the stopper However, if the cover plate shifts even slightly, it becomes difficult to fit the cover plate together. remove the defect In order to remove the seal, either lengthen the seal tube or insert the gas from the rear inner surface of the seal tube. It should be possible to hang the guide piece vertically, but if the seal tube is made long, the seal tube will not be able to hold the finger. If the lid hits the ring and the lid closes incompletely, and if a guide piece like the one above is installed vertically, The rear part of the seal cylinder to which the base end of the guide piece is attached has a thick wall, so the synthetic When the lid is integrally molded with a resin material, when it cools down, the thick seal cylinder part is removed. A so-called sink mark is formed on the surface, and the sink mark does not allow a watertight seal between the spout tube and the seal tube. There was a drawback that would go away.

0004 This proposal eliminates such drawbacks and also makes it easy to fit the seal tube into the spout tube. It is designed to be easy and reliable.

[0005]

[Means to solve the problem]

A first peripheral wall 3 is vertically installed from the outer periphery of the first top wall 2 to the upper outer surface of the mouth and neck of the container body. At the same time, the central part of the first top wall is formed into a peeling plate 6 by providing five thin broken lines around it, and A protruding piece 8 with a finger ring 7 is erected from a part of the outer periphery of the release plate, and the above-mentioned breaking line is further surrounded. The spout tube 9 is placed higher than the finger ring 7 from the first top wall portion, and from the outside of the first top wall. The short fitting tubes 10 are respectively erected from the upper surface of the first top wall with a small gap left between the plugs and the peripheries. The body 1 and the seal cylinder 12, which is watertightly fitted to the inner surface of the upper part of the spout cylinder 9, are placed under the second top wall 13. The second circumferential wall 14 fitted to the outer surface of the short fitting tube 10 is then inserted from the outer circumference of the second top wall. Each of the first peripheral wall 3 and the second peripheral wall 14 has a vertically disposed lid plate 11. A lid that is connected with a hinge 15 and is entirely molded from synthetic resin material so that it can be opened and closed. , from the lower end of the rear part of the seal cylinder 12 close to the hinge 15, When closing the lid plate 11 by rotating around 15, it contacts the inner edge of the upper end of the spouting tube 9. The elastic guide piece 18 that guides the seal tube 12 to the upper inner surface of the spout tube is short and lower front. It was curved in the direction and protruded.

[0006]

[Effect]

When the lid plate 11 is pushed up against the stopper 1 from the open state of Fig. 1, the hinge 15 The lid plate 11 rotates until the tip of the elastic guide piece 18 comes into contact with the upper end of the spout tube 9, as shown in FIG. Then, by continuing to push down the lid plate, the elastic guide piece 18 is elastically deformed and the inner surface of the spout tube 9 is pressed down. The seal cylinder 12 is fitted into the upper end of the spout cylinder 9 under the guidance of the guide piece.

[0007]

【Example】

First, to explain the conventionally known structure, reference numeral 1 denotes a stopper, and a plug is inserted from the outer periphery of the first top wall 2. The first peripheral wall 3 to be fitted onto the upper outer surface of the mouth and neck of the vessel is also inserted into the mouth and neck from the back surface of the first top wall. The inner peripheral walls 4 to be fitted onto the surfaces are respectively suspended. The first top wall portion surrounded by the inner peripheral wall is recessed, and the central part of the first top wall within the recess is provided with five thin fracture lines around it to form a peeling plate 6. A projecting piece 8 with a finger ring 7 stands up from a part of the outer periphery of the peeling plate. Mataue The circumferential wall of the recessed part is extended upward to raise the spouting tube 9 higher than the finger ring 7. , the upper end of the spout tube is curved outward. Also, between the first top wall 2 and the outer periphery The short fitting tube 10 is erected from the upper surface of the first top wall 2, leaving a small gap between the two.

[0008] Reference numeral 11 denotes a cover plate, which has a seal fitted watertightly to the inner surface of the upper part of the pouring tube 9, as shown in Fig. 3. The second circumferential wall 14, in which the cylinder 12 is fitted from the lower surface of the second top wall 13 to the outer surface of the short fitting cylinder 10, is Each is installed vertically from the outer periphery of the top wall.

[0009] The plug body 1 and the lid plate 11 are integrally connected by a hinge 15 and made of synthetic resin. The hinge 15 allows the lid plate to be opened and closed at the rear of each of the first peripheral wall 3 and the second peripheral wall 14. Connect to ability. The illustrated hinge is connected by a pair of left and right elastic plates 16, 16, but other It may be connected. A finger hook protrusion 17 is attached to the lower front end of the second peripheral wall.

0010 In this proposal, in the lid stopper with the above structure, the rear lower end of the seal cylinder 12 close to the hinge 15 is When closing the lid plate 11 by rotating around the hinge 15, the spout tube 9 An elastic guide piece 18 is attached to the inner edge of the upper end and guides the seal tube 12 to the upper inner surface of the spout tube. , curved and protruding downward and forward.

[0011]

[Effect of the idea]

In this case, the elastic guide piece 18 is provided protruding from the rear lower end portion of the seal cylinder 12. The seal cylinder part above the guide piece of the seal cylinder should not be thicker than the other seal cylinder parts. Therefore, when the cap is cooled after molding, the rear surface of the seal cylinder with the elastic guide piece is exposed to heat. A concave surface is formed by the groove, and the concave surface makes it impossible to fit the spout tube and the seal tube in a watertight manner. In addition, the elastic guide piece 18 is short and curved downward and forward. Then, the tip of the guide piece hit the finger ring 7 of the stopper, which caused the lid to close incompletely. It will never happen.
