  The cutting blade member 5 and the hinge 6 can be integrally formed with the inner cap 4 by, for example, injection molding using synthetic resin.

  An overcap 9, also called an outer lid, is detachably attached to the outer side of the inner cap 4. The overcap 9 is made of, for example, a synthetic resin. The inner cap 4 is covered with an overcap 9 to prevent the container body 2 from being unsealed due to an erroneous operation of the cutting blade member 5 during distribution or the like, and to prevent the drinking mouth 4d of the side wall portion 4c from becoming dirty. The

  The overcap 9 is formed in a bottomed cylindrical shape including a cylindrical side wall 9a along the outer periphery of the side wall portion 4c of the inner cap 4 and a top wall 9b connected to the side wall 9a. A mounting cylindrical portion 9c formed in a cylindrical shape having a larger diameter than the side wall 9a is integrally provided on the side wall 9a via a connecting piece 9d. A locking piece 9e that protrudes in a U-shape toward the radially inner side is integrally provided at the tip of the mounting cylindrical portion 9c, and this locking piece 9e is provided at the tip of the mounting claw portion 4e of the inner cap 4. By engaging the undercut, the overcap 9 is detachably attached to the outside of the inner cap 4.

  The top wall 9b of the overcap 9 is provided with a recess 9f formed to have a diameter slightly larger than the outer diameter of the bottom portion 2b of the container body 2. The concave portion 9f is disposed when the bottom portion 2b of the container body 2 of the other overcap-equipped container 1 is disposed as shown by a two-dot chain line in FIG. And is formed in a circular shape concentric with the top wall 9b.

  The overcap 9 is integrally provided with a pushing portion 10 in order to open a temporary hole in the sealing sheet 3 without removing the overcap 9. The pushing portion 10 is provided at a position corresponding to the cutting blade member 5 of the recess 9f, that is, above the cutting blade member 5, and is displaced toward the cutting blade member 5 by being pushed toward the cutting blade member 5. In other words, it moves so that the cutting blade member 5 can be rotated from the initial posture to the temporary opening posture.

  The top wall 9b of the overcap 9 is provided with an inclined wall 9g inclined downward from the surface of the recess 9f toward the drinking mouth 4d, and a connecting wall 9h connecting the inclined wall 9g to the recess 9f. A bellows portion 11 is integrally provided between the wall 9g and the connecting wall 9h. The bellows portion 11 is formed in a wave shape in the up-down direction, that is, in a direction approaching / separating from the cutting blade member 5, and can be extended downward by elastic deformation. When the bellows part 11 extends downward, the inclined wall 9g moves downward, that is, toward the cutting blade member 5 while tilting in the direction of increasing the inclination with a portion directly connected to the top wall 9b as a fulcrum.

  The pushing portion 10 is formed in a bottomed cylindrical shape that opens on the side of the cutting blade member 5, and is provided integrally with the inclined wall 9g at the lower end of the inclined wall 9g. That is, the pushing portion 10 is formed in a circular convex shape that projects from the inclined wall 9g toward the side opposite to the cutting blade member 5. Since the pushing portion 10 is provided at the lower end of the inclined wall 9g, the outer peripheral edge along the lower end of the inclined wall 9g is connected to the connecting wall 9h via the bellows portion 11. A predetermined range of the push-in portion 10 facing the upper side of the inclined wall 9g is connected to the inclined wall 9g without the bellows portion 11 interposed therebetween.

  In the initial position shown in FIG. 1, the pushing portion 10 has an upper surface that does not protrude into the recessed portion 9f. That is, the pushing portion 10 is disposed closer to the cutting blade member 5 than the recessed portion 9f. Yes. Thereby, as shown by a two-dot chain line in FIG. 1, even when the same kind of overcap-equipped container 1 is stacked on the concave portion 9f of the overcap 9 during distribution, the overcap container in which the pushing portion 10 is stacked. The sealing sheet 3 is prevented from being unintentionally opened by being pushed by the bottom portion 2b.

  The pushing portion 10 can be integrally formed with the overcap 9 by, for example, injection molding using a synthetic resin.

  Next, a procedure for opening a temporary hole for pressure relief in the sealing sheet 3 when the beverage filled in the overcap-equipped container 1 is heated by a heating device such as a microwave oven will be described.

  As shown in FIG. 1, at the time of distribution or the like, the cutting blade member 5 of the container 1 with an overcap is in an initial posture to be separated upward with respect to the sealing sheet 3, and the pushing portion 10 has the cutting blade member 5. The initial position is spaced upward.

  When the beverage filled in the overcap-equipped container 1 is warmed by a heating device such as a microwave oven, in order to prevent the container body 2 from bursting due to an increase in internal pressure, the pushing portion 10 of the overcap 9 is A temporary hole for pressure release can be opened in the sealing sheet 3 by pushing toward the cutting blade member 5.

  As shown in FIG. 3, when the pushing portion 10 provided in the overcap 9 is pushed downward, that is, toward the cutting blade member 5, before heating, the bellows portion 11 is elastically deformed and extends downward, and the inclined wall 9g moves downward, that is, toward the cutting blade member 5 while increasing the inclination. When the inclined wall 9g moves downward, the pushing portion 10 moves downward toward the cutting blade member 5 and pushes down the cutting blade member 5 in the initial posture downward.

  When the pushing portion 10 moves to the pushing position, the cutting blade member 5 is pushed by the pushing portion 10 and rotates to the temporary opening posture. The temporary opening posture is a posture in front of the opening posture in which the cutting blade member 5 forms the spout on the sealing sheet 3, and the cutting blade member 5 is at the same angle as the inclined wall 9g along the inclined wall 9g. Tilt. When the cutting blade member 5 is rotated to the temporary opening posture, the tip portion of the blade 5c slightly breaks the sealing sheet 3, and the temporary hole 12 is opened in the sealing sheet 3. The temporary hole 12 is smaller than the spout formed in the sealing sheet 3 by turning the cutting blade member 5 to the opening posture, and has a size such that the beverage cannot be easily poured out from the container body 2.

  Here, when the pushing portion 10 is pushed to the pushing position and the cutting blade member 5 is in the temporary opening posture, the operation portion 5b of the cutting blade member 5 comes into contact with the inclined wall 9g and functions as a stopper. Further rotation is restricted. Thereby, it is prevented that the cutting blade member 5 rotates excessively and the temporary hole 12 larger than necessary is opened in the sealing sheet 3.

  In this way, by pushing the pushing portion 10 provided on the overcap 9 toward the cutting blade member 5 and displacing it to the pushing position, the cutting blade member 5 is rotated to the temporary opening posture, and the sealing sheet 3 A temporary hole 12 having a predetermined size can be opened. That is, without removing the overcap 9 and the inner cap 4 from the container body 2, the temporary hole 12 can be formed in the sealing sheet 3 by a simple operation of pushing the pushing portion 10 provided on the overcap 9 toward the cutting blade member 5. Can be opened. Therefore, when the beverage is heated, the temporary cap 12 for depressurization can be opened in the sealing sheet 3 without performing the attaching / detaching operation of the overcap 9 or the operation of the cutting blade member 5. The heating operation of the beverage filled in 1 can be facilitated.

  Further, since the inner cap 4 is covered with the overcap 9, even if the pressing portion 10 provided in the overcap 9 is pressed to open the temporary hole 12 in the sealing sheet 3, the inner cap 4 and the sealing sheet 3 are touched by the hand. There is nothing. Therefore, the container 1 with an overcap can be made more hygienic by avoiding, for example, the hand of an operator such as a store clerk from touching the broken portion of the drinking mouth 4d of the inner cap 4 or the sealing sheet 3 during the heating operation. Can do.

  Furthermore, in this container 1 with an overcap, since the pushing part 10 is connected to the top wall 9b (connecting wall 9h) of the container 1 with an overcap through the bellows part 11, the pushing part 10 is made into a cutting blade. It can be easily displaced toward the member 5.

  When the temporary hole 12 is opened in the sealing sheet 3, the container 1 with an overcap is put into a heating device such as a microwave oven, and the beverage is heated. At this time, since the temporary hole 12 opened in the sealing sheet 3 functions as a pressure releasing hole for releasing the pressure inside the container body 2, the pressure inside the container body 2 even if the beverage is heated excessively. Does not escape from the temporary hole 12 and the container body 2 does not burst.

  As shown in FIG. 4, when the heating of the beverage by a heating device such as a microwave oven is completed, the overcap 9 is removed from the inner cap 4. Next, when the operation portion 5b of the cutting blade member 5 is further pulled upward, the cutting blade member 5 is rotated to the opening position with the hinge 6 as a fulcrum, and the sealing sheet 3 is broken by the blade 5c of the cutting blade portion 5a. As a result, the spout 13 is formed in the sealing sheet 3.

  When the cutting blade member 5 is rotated to the opening position, as shown in FIG. 5, a substantially rectangular opening 14 surrounded by the inner wall 4 a of the inner cap 4, the pair of operation portions 5 b of the cutting blade member 5 and the hinge 6 is formed. An inner cap 4 is formed. Thus, when the container body 2 is tilted, the beverage poured out from the spout 13 of the sealing sheet 3 is poured out into the drinking mouth 4d of the inner cap 4 through the opening 14.

  FIG. 6 is a cross-sectional view of a container with an overcap according to another embodiment of the present invention. In FIG. 6, members corresponding to those described above are denoted by the same reference numerals, and repeated description thereof is omitted.

  As shown in FIG. 7, the cutting blade member 5 provided in the inner cap 4 of the overcap-equipped container 21 has a cutting blade portion 5 a formed in a substantially rectangular shape having the same width as the hinge 6. The pair of operation portions 5b of the cutting blade member 5 are formed in a wing shape extending from both sides of the cutting blade portion 5a toward the opposite side of the hinge 6 with respect to the cutting blade portion 5a. The interval of 5b is adjusted to the width of the cutting edge portion 5a. The cutting blade member 5 is connected to the bottom wall 4h by a virgin type connecting piece 22 and is held in an initial posture. When opening, the connecting piece 22 is cut to rotate the cutting blade member 5. Yes. The bottom wall 4h of the inner cap 4 is provided with a pair of locking pieces 23. When the cutting blade member 5 is rotated to the opening position, the locking piece 23 has a width of the operation portion 4b. The direction outer edge part is engaged, and the cutting blade member 5 is held in the opening position.

  Moreover, in the container 21 with an overcap shown in FIG. 6, the pushing part 10 provided in the overcap 9 is formed in the cylindrical shape with a bottom which opens toward the opposite side to the cutting blade member 5, ie, the concave shape of a cross section. ing. The pushing portion 10 is connected to the top wall 9b of the overcap 9 through the bellows portion 11 at the entire outer periphery thereof, and the bellows portion 11 extends downward due to elastic deformation, whereby the cutting blade member It is possible to move in parallel toward 5. An inclined portion 24 that is inclined downward toward the drinking mouth 4d is provided at a portion of the push-in portion 10 that faces away from the drinking mouth 4d. The inclination angle of the inclined portion 24 corresponds to the inclination angle of the cutting blade member 5 in the temporary opening posture.

  In the container 21 with an overcap shown in FIG. 6, an annular groove 25 is provided in the top wall 9 b of the overcap 9, and when the same kind of overcapped container 1 is stacked on the overcap 9 during distribution or the like, The bottom portion 2b of the container 1 with an overcap is arranged in the groove 25. Also in this case, the pushing portion 10 is disposed at a position lower than the groove 25, that is, shifted toward the cutting blade member 5 from the groove 25 in the initial position shown in FIG. 6. Thereby, even when the same kind of overcap-equipped container 1 is overlaid on the top wall 9b of the overcap 9 during distribution, the pushing portion 10 is pushed by the bottom portion 2b of the overcap container 1 overlaid, The sealing sheet 3 is prevented from being opened accidentally.

  Next, the procedure for opening the temporary holes 12 for pressure release in the sealing sheet 3 when the beverage filled in the container 21 with an overcap shown in FIG. 6 is heated by a heating device such as a microwave oven will be described.

  Also in the case shown in FIG. 6, the cutting blade member 5 of the container 21 with an overcap is in the initial posture of separating upward with respect to the sealing sheet 3 during distribution, etc., and the pushing portion 10 is the cutting blade member. 5 is an initial position that is separated upward.

  As shown in FIG. 8, when the pushing portion 10 provided on the overcap 9 is pushed downward, that is, toward the cutting blade member 5 before heating, the bellows portion 11 extends downward due to elastic deformation, and the pushing portion 10 moves in parallel downward. Thereby, the cutting blade member 5 is pushed downward from the initial posture by the pushing portion 10.

  When the pushing portion 10 moves to the pushing position, the cutting blade member 5 is pushed by the pushing portion 10 and is rotated to the temporary opening posture, and the tip portion of the blade 5c slightly breaks the sealing sheet 3 to seal the blade. Temporary holes 12 are opened in the sheet 3. At this time, the cutting blade member 5 comes into contact with the inclined portion 24 of the push-in portion 10 and is held in a temporary opening posture along the inclined portion 24.

  When the cutting blade member 5 is rotated to the temporary opening posture, the operation portion 5b of the cutting blade member 5 comes into contact with the inner surface of the top wall 9b of the overcap 9, and this operation portion 5b functions as a stopper, Further rotation of the blade member 5 is restricted. Thereby, it is prevented that the cutting blade member 5 rotates excessively and the temporary hole 12 larger than necessary is opened in the sealing sheet 3.

  Thus, also in the container 21 with an overcap shown in FIG. 6, by pushing the pushing part 10 provided in the overcap 9 toward the cutting blade member 5, the cutting blade member 5 is made into the sealing sheet 3 together with the pushing part 10.
