Abstract

PROBLEM TO BE SOLVED: To enhance yield of a container body and eliminate malfunction such as functional leakage or the like. SOLUTION: The synthetic resin plug comprises a base 8 molded of rigid synthetic resin for covering a mouth 4 of a container body 1, an ejection hole 12 placed at the center of the base 8, and an in-fitting part 10 hanging from a lower face of the base 8 to be inserted into the mouth 4 of the container body 1, wherein a sealed part 15 molded of a flexible material is provided from an outer wall of the in-fitting part 10 to a contact face 14 where a tip of a neck 3 of the container body 1 is in contact, and the sealed part 15 seals an inner wall of the neck 3 of the container body 1 and a tip of the neck 3. A circular rib 19 with which the tip of the neck 3 of the container body 1 comes into contact may hang on the contact face 14 of the sealed part 15.

Description of the Related Art Conventionally, a container for storing a liquid content having a relatively low viscosity such as a lotion, a hairdressing agent, a medicine, etc. has a plug provided with a discharge port for discharging the content at the mouth of the container. The discharge port was fitted with a cap which was fitted. For this container body, one made of glass or synthetic resin was used. Further, as means for sealing the discharge port, an elastic packing such as a soft resin is disposed inside the cap, and this packing is brought into contact with the upper surface of the plug body to perform the sealing by the elasticity of the packing.

プの要因となっていた。However, since many containers made of glass or synthetic resin are formed by a molding method similar to hollow molding, the inner diameter of the opening, which is particularly important for fitting the plug, is important. The shape and the size of the sample tend to fluctuate, and there is a danger of liquid leakage from the plug, and high-precision size control is required. For this reason, the production yield is low, and this has been a factor of cost increase.

たりした。[0004] Further, in the case of a container with a cross section of a different shape, which emphasizes design, a positioning mechanism is provided on the cap so that the outer shape matches when the container is fitted. Because of this cap positioning mechanism, there is no means for retightening the cap when the packing comes off due to repeated insertion and removal of the cap, and there is a risk of liquid leakage. To solve this problem, extra parts had to be added, which resulted in design restrictions and increased costs.

It is possible to prevent liquid leakage other than the pouring hole 12. In addition, if the sealing portion 15 is within the range of deformation, the container main body 1 mouth 4 can be securely sealed, so that the allowable range of the shape and dimensions of the inner diameter of the container main body 1 mouth 4 is widened, and The yield can be improved. In addition, by providing the annular rib 19 in the sealing part 15, the amount of deflection of the sealing part 15 can be further increased, and the allowable range of the inner diameter of the mouth part 4 can be further expanded.

る。Further, when the cap 16 is fitted to the container body 1, the plug 7 is
Is sealed, but since the elasticity of the sealing portion 15 of the plug 7 can be utilized in addition to the elasticity of the packing 18, the sealing portion 15 compensates for the load of the packing 18 and extends the life of the packing 18. You can do it. In addition, by hanging the annular rib 19 on the sealing portion 15, the amount of bending of the sealing portion 15 can be further increased, and the load on the packing 18 can be further reduced. Therefore, when the present invention is applied to a container having an alignment mechanism for the cap 16 used for a container having a different cross-section, since the settling of the packing 18 can be prevented without adding a special configuration, Design restrictions can be relaxed without increasing costs.
