いる。The container body 1 of the present invention is made of a synthetic resin formed by injection molding, and has a cylindrical mouth and neck portion 4 erected through a shoulder 3 from an upper end edge of a cylindrical body portion 2 having an opened lower end surface. Make up.
【００１０】又、口頚部４頂面の内周縁部を下方へ凹ま
せてリング状の凹部５を形成しており、この凹部５によ
り口頚部４頂面の平滑性を維持させる如く構成してい
る。A ring-shaped recess 5 is formed by recessing the inner peripheral edge of the top surface of the mouth and neck 4 downward, and the recess 5 is configured to maintain the smoothness of the top surface of the mouth and neck 4. I have.

上がって盛り上げ部８を形成する場合がある。しかしな
がら、この盛り上げ部８は凹部５内に形成されるため、
口頚部４頂面の平滑性は保たれる訳である。That is, as shown in FIG. 2, the recess 5 is connected and supported by a gate 7 having an end connected to the upper end of the inner surface of the mouth and neck 4 through a runner 6 during injection molding.
When the gate 7 is cut, as shown in FIG. 3, the cut end piece of the gate 7 may rise into the recess 5 to form a raised portion 8. However, since the raised portion 8 is formed in the concave portion 5,
This means that the smoothness of the top surface of the mouth and neck 4 is maintained.
【００１２】従って、この凹部５は上記実施例の如き口
頚部頂面内周縁部に周設する場合に限らず、ゲート近傍
の口頚部頂面内周縁部に設ければ良く、上記実施例の場
合の如く４箇所のゲートの有る場合には４箇所の凹部を
設けても良い。又、ゲートの数が一箇所或いはその他の
複数箇所の場合には、その数だけ凹部５を設けることも
可能である。Therefore, the recess 5 is not limited to being provided on the inner peripheral edge of the top face of the mouth and neck as in the above embodiment, but may be provided on the inner peripheral edge of the top face of the mouth and neck near the gate. it may be a recess at four positions in the case where the gate closed Ru in four places as is the case. In the case where the number of gates is one or a plurality of other places, it is possible to provide the recesses 5 by the number.
