Description

The present invention relates to a container with a straw in which a straw is inserted into the container body.

The container with a straw is provided with a stopper for accommodating the tip of the straw so that the suction part at the tip of the straw does not touch the outside air when not in use. For example, there is known a straw container including a plug member that is detachably fitted to a mouth portion of a container body and a lid member that is pivotally supported by the plug member (Patent Document 1).
JP 2003-205958 A

However, in the container with a straw described in Patent Document 1, when the lid member is opened, the straw stored in a bent state rises with an elastic force, so that a high-temperature liquid or the like is stored in the container body. When the pressure in the container increases and the liquid in the container rises to the tip of the straw, the liquid may be ejected from the straw.

  The main object of this invention is to provide the container with a straw which can release the pressure in a container body before a straw stands up.

  Another object of the present invention is to provide a container with a straw having a simple structure.

  Still another object of the present invention is to provide a container with a straw that can be easily disassembled and assembled.

The present invention includes an adapter 10 in which a valve hole 14 and a through hole 15 are formed in a top plate 12 of a top peripheral wall 11 detachably fitted to the outer surface of a container body 1;
A pair of through holes are formed in the valve receiving member 31 disposed on the lower surface of the adapter top plate 12, and the upper and lower intermediate portions of the valve cylinder 35 rising from the periphery of one of the through holes are fitted into the valve hole 14, and the other An elastically deformable straw holding member 30 formed with the upper protruding portion of the through tube 36 penetrating through the through-hole 36 in the straw portion 37 and the lower protruding portion in the straw holding portion 39, respectively.
A valve shaft 43 is suspended from a top wall 42 depending on a hanging cylinder 45 threadedly engaged with a standing cylinder 13 rising from the adapter top plate 12, and a reduced diameter portion 44 formed at the upper and lower intermediate portions of the valve shaft is An operation cap 40 is inserted into the valve cylinder 35 so as to be movable up and down, and the upper and lower surfaces of the reduced diameter portion are formed as seal portions, and further, a long hole 48 through which the straw portion 37 is inserted is formed in the top wall 42. Prepared,
The valve shaft 43 is provided detachably upward from the valve cylinder 35 by forcibly turning the operation cap 40 in the opening direction from the open position.

Further, according to the present invention, when the operation cap 40 is rotated in the closing direction, the straw portion 37 is engaged with one end of the long hole 48 and can be stored in the operation cap while falling down. An upper surface seal portion of the portion 44 abuts on the upper end of the valve cylinder 35 so that the valve can be closed, and a lower surface seal portion is provided so as to be spaced apart downward from the valve receiving member 31 and opened.
By rotating the operation cap 40 in the opening direction, the straw portion 37 can protrude from the elongated hole 48 to the outside of the operation cap, and the upper surface seal portion of the valve shaft reduced diameter portion 44 is spaced apart from the valve cylinder 35 upward. Are provided so that the valve can be opened and the bottom seal portion can be closed by contacting the valve receiving member 31,
At the intermediate position between the closed position and the open position of the operation cap, the seal portions on both the upper and lower surfaces of the valve shaft diameter-reduced portion are opened away from the valve cylinder and the valve receiving member, so that the pressure in the container body is increased. It is provided with releasability.

  Further, according to the present invention, the valve shaft 43 has a fitting cylinder 45 depending from the top wall 42, and an upper part of the fitting cylinder 45 depending on the fitting cylinder 45, and the lower end portion is formed in the enlarged diameter portion 46. Thus, a portion between the lower end of the fitting cylinder 45 and the enlarged diameter portion 46 is constituted by a cylindrical valve body 47 formed in the reduced diameter portion 44.

  Furthermore, the present invention is characterized in that the straw holding member 39 is made of an elastomer.

  Furthermore, the present invention is characterized in that the adapter 10 is provided with a closing plate 50 capable of closing the elongated hole 48 from below when the operation cap 40 is closed.

  Furthermore, the present invention is characterized in that a handle 70 projects from the adapter peripheral wall 11.

  In the present invention, since the inside of the container body can be communicated with the outside air when the operation cap for storing or standing the straw section is rotated, the pressure in the container body is released when the straw section is raised, and the inside of the straw section is released. Therefore, the liquid is not ejected from the straw portion when the straw portion is erected.

  In addition, the present invention uses the threaded portion of the upright cylinder rising from the adapter top plate and the suspended cylinder from the top wall of the operation cap as an outflow path for high-pressure air, and the air outflow path can be opened and closed by turning the operation cap. Since it is possible, the configuration is simple.

  Furthermore, the present invention provides the valve shaft so that it can be detached upward from the valve cylinder by forcibly turning the operation cap in the opening direction from the open position, so that the operation cap can be detached from the adapter and disassembled. Therefore, the inside of the operation cap can be easily cleaned.

  Furthermore, since the closing plate which can close | close a long hole from the downward direction is provided in this invention in the closed position of an operation cap, the designability improves.

The present invention will be described below with reference to embodiments shown in the drawings.
