container with unsealing unit

Abstract

PROBLEM TO BE SOLVED: To provide a container including an unsealing means attached thereto and capable of easily forming a favorable unsealing hole without abnormally deforming and damaging a peripheral part of a sealing film of a container body.SOLUTION: The container includes the container body, a cap 4 and an unsealing / spout member 5. The unsealing / spout member 5 includes: the unsealing means; an engagement part brought into a come-off prevention state with respect to a neck of the container body; and a spout capable of spouting a content of the container body when the unsealing / spout member 5 is locked on the neck of the container body in the come-off preventing state. While being held by a holding part 43b of the cap, the unsealing / spout member is moved to a barrel side together with the cap accompanied by the rotation of the cap during screwing, and when an unsealing possible part 24 at an upper end of the neck is unsealed by the unsealing means to form the unsealing hole, the engagement part is engaged with a lock 25 so as to be brought into the come-off prevention state with respect to the neck 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
