Description

  The present invention provides a liquid container having two different types of plugs for different purposes by replacing two different types of plugs in the same container body in a liquid container such as a portable thermos, a tabletop thermos, and a water bottle. Related to container closures.

  2. Description of the Related Art Conventionally, a stopper for a liquid container of this type includes: (a) an indirect drinking stopper in which a container body is inclined so that a content liquid is poured into a cup or the like from a spout of a liquid passage in a stopper, or a straw. There is known a direct-drinking plug which directly attaches a mouth to a mouthpiece to drink a liquid content.

    Since the above-mentioned plug for indirect drinking and the plug for direct drinking have different structures, the container body of the liquid container into which the plugs are removably inserted has a different structure, depending on the purpose of use. It was necessary to use separate liquid containers. In other words, there has been a problem that the conventional stopper of a liquid container cannot be selectively used for indirect drinking or direct drinking for one container body.

    In order to solve such a problem, (b) a stopper for a liquid container disclosed in JP-A-9-313363 is known. The stopper of the liquid container described in this publication includes one stopper having two systems of liquid passages, a first liquid passage for indirect drinking and a second liquid passage for direct drinking, in a stopper hole of one container body. A first valve body that is removably fitted to open and close the first liquid passage, a second valve body that opens and closes the second liquid passage, and a spout member used as opening and closing means for the first and second valve bodies. The spout member can be operated in two different modes by an external operation, and the first liquid passage is closed while the second liquid passage is closed during the operation of the one embodiment, In the operation of another mode, the second liquid passage is opened and closed while the first liquid passage is closed.

According to the above (b), one plug body is inserted into one container body, and a predetermined operation is performed, whereby the container can be switched between indirect drinking and direct drinking. Therefore, it is extremely convenient as compared with the conventional example (a).
JP-A-9-313363

  However, in the above (b), a large number of parts such as the second liquid passage, the second valve body, the spout member, and the spout opening / closing member must be incorporated into one stopper, and not only the number of parts increases, but also the number of parts increases. There is a disadvantage that the structure is complicated.

  In addition, opening and closing the first liquid passage and the second liquid passage requires a different operation such as vertical movement of the spout member or rotation / sliding, so that when the user operates, it is complicated and troublesome. There are problems.

    The present invention is intended to solve the above-mentioned problems of the conventional examples (a) and (b), and comprises two plugs, an indirect drinking plug and a direct drinking plug which can be replaced with a stopper hole of one container body. By using different types of stoppers, not only can indirect drinking or direct drinking be selected and used, but also both stoppers can prevent the increase in the number of parts and simplify the structure, and furthermore, can be used for indirect drinking It is an object of the present invention to provide a liquid container stopper that can be easily and easily and reliably performed by a user for each operation of direct drinking.

      In order to achieve the above object, the present invention provides a substantially cylindrical plug body detachably screwed into a plug hole of a container body, and a plug between the plug body detachably provided in the plug body. A first plug sub-body of an indirect drinking plug and a second plug sub-body of a direct drinking plug in which an internal liquid passage is formed; and a common valve element for opening and closing the internal liquid passage. By replacing the first plug sub-body and the second plug sub-body with respect to the main body, the plug body can be selectively used as a plug for indirect drinking or a plug for direct drinking, and the valve body is composed of the first plug sub-body and the second plug sub-body. The liquid passage in the plug is opened / closed by being operated by operating a valve opening / closing mechanism provided in the plug sub-body (see claim 1).

  Here, a single plug body can be used in common as a plug for indirect drinking and a plug for direct drinking, and a plug subbody is a first plug subbody for indirect drinking plugs and a plug for direct drinking. The first plug sub-body and the second plug sub-body are replaced with respect to the plug main body, and can be selectively used as an indirect drinking plug or a direct drinking plug. With such a configuration, the number of parts can be reduced and the structure is simplified.

  The structure in which the plug for indirect drinking and the plug for direct drinking are fitted into the plug hole of the container body and fixed to the container body is not particularly limited in the present invention, and is arbitrary.

  In the present invention, the first plug sub-body and the second plug sub-body each have an empty chamber at an upper part and a valve rod insertion hole at a bottom part, and a guide cylinder is provided upright at a lower part of the empty chamber of the plug main body. Then, one of the first plug sub-body and the second plug sub-body is selected and attached to the upper part of the guide tube, and the valve plug insertion hole of the attached first plug sub-body or second plug sub-body is inserted into the valve stem insertion hole. When the valve is closed, the lower part of the liquid passage in the plug is closed by the valve body, and the liquid passage inside the stopper is automatically opened and closed by the valve opening and closing mechanism. It can be opened and closed automatically (see claim 2).

  According to the first aspect of the present invention, the first plug subbody for the indirect drinking plug and the direct drinking plug for one stopper body detachably screwed into the stopper hole of the container body. By replacing the second plug sub-body, the plug can be selectively used as an indirect drinking plug or a direct drinking plug, and the plug body can be shared, so that the number of parts can be further reduced and the structure can be simplified. In addition, by operating the valve opening / closing mechanism provided on the first plug sub-body and the second plug sub-body, the valve body easily opens and closes the liquid passage in the plug.
