Container with unsealing means

Abstract

A container including an opening unit is provided to enable users to easily and uniformly form an opening without deforming or breaking the peripheral area of a bag film of a container main body. A container includes a container body, a cap, and an opening and main discharging member. The container body includes the following components: a cylindrical head with an openable unit at the upper end, a hook-stopping unit for stopping the opening and main discharging member, and external screw thread on an outer circumferential surface; and a body part. The opening and main discharging member is provided with the following components: an unsealing unit which is provided with an opening / sealing hole; a jointing part which is jointed with the hook-stopping unit, thereby causing the opening and main discharging member in an anti-releasing state at the head of the container body; and an injection-out opening which can inject inner object out when the opening and main discharging member is stopped at the head part of the container body. When the injection-out opening moves to the body side along with the rotation of the cover in screwing with the cover, and the unsealing unit is used for opening and closing the openable unit, the jointing part is jointed with the hook-stopping unit, thereby forming the anti-releasing state at the head of the container body.

Description

technical field [0001] The invention relates to a container with an unsealing unit. More specifically, the present invention relates to a container with an unsealing / spout member for unsealing a sealing film of a container body filled with contents and constituting a spout for the contents. Background technique [0002] Conventionally, many containers have been disclosed in which the spout is kept sealed when not in use, and the sealing film provided on the spout is unsealed for use at the beginning of use. Furthermore, there is also known a lid structure with an unauthorized opening prevention mechanism (unsealing prevention member) that prevents the lid from being accidentally opened in an unused state. [0003] In the patent document 1 (Japanese Patent No. 3024089 communique) proposed by the applicant before, there are following records: in the following bottle container, that is, on the head of the container body filled with the content, seal and fix the anti-open seal ...

AI Technical Summary

Problems solved by technology

However, there are problems in that traces of the anti-tampering member are left, which is unsatisfactory in terms of appearance, and it is necessary to press the exterior cover with a relatively large force when opening the seal.

Although there are many advantages in this prior art, because the rotation of the lid when screwing is used to unseal, so the unseal can be easily performed with a relatively small force, but there is the following problem: the formed unsealed hole is only Limited to very small holes, it is difficult to apply to containers that require relatively large opening holes

However, it has been recognized that there is a problem that if this technique is applied to a container body of a relatively high bending or flexible material such as a squeezed tubular container, or the rotational force applied to form a large-diameter cap is greatly increased In the case of a container body with a relatively small unsealing hole, not only a relatively large pressing force but also a large rotational force will act on the periphery of the sealing film, so the peripheral portion of the sealing film will be deformed abnormally. or damaged
