Description

  The present invention relates to a lid device used in a mixing container in which two types of contents stored separately are mixed by performing a predetermined operation.

  2. Description of the Related Art Conventionally, there has been known a mixing container in which two substances separated and stored until immediately before use are mixed for the first time at the time of use as shown in FIGS. In the figure, 11 is a hollow cylindrical lid for storing the first substance, and 21 is a container main body that is sealed by being screwed together with the lid 11 and sealed to store the second substance. The lid 11 has the opening 10 closed with a sealing member 12 such as an aluminum foil so that the filled contents do not leak. The seal breaker 13 includes a flanged top plate 131 that covers the top of the lid 11 and a cylindrical portion 132 that extends integrally from the bottom surface of the top plate 131 and is loosely fitted into the lid 11. A breaking blade 133 is formed on the lower end surface of the blade. The seal breaker 13 is mounted on the lid 11, and presses the top plate 131 to break the seal member 12 with the break blade 133. Between the seal breaker 13 and the lid 11, a belt-like stopper 14 is usually provided to keep the seal breaker 13 in the raised state, and the lid 11 and the seal are sealed at equal intervals in the circumferential direction on the upper and lower ends of the stopper 14. A plurality of connecting projections 141 connected to the breaking tool 13 are provided, and a protruding knob 142 is provided on a part of the outer peripheral surface. When the knob 142 is pulled with a finger or the like, the seal breaking tool 13 is detached from the container. Make it possible to descend.

  As shown in FIG. 8, the container contains two kinds of substances (not shown) separated from each other. When the container is in use, the stopper 14 is pulled away from the container, and the seal breaker 13 is pushed down vigorously. 9 and 10, the lowermost end surface portion 134 corresponding to the breaking blade 133 approaches the peripheral edge portion 121 of the sealing portion 123 attached to the lower end edge of the lid body 11 of the sealing member 12, and the sealing member 12. Break through. When the seal member 12 is broken, the contents put in the lid body 11 fall or flow into the container main body 21 from the breakage gap 122 and are mixed with the contents in the container main body 21. On the other hand, in order to prevent broken pieces of the seal member 12 from falling into the container, the peripheral portion 121 of the seal member 12 is broken so that it is broken to 1/4 or 1/3 of the entire peripheral edge of the seal member 12. The descending altitude of the tool 13 is determined, and the height of the stopper 14 is also made.

  However, in the mixing container, the two substances can be kept in an isolated state. However, when the seal breaker 13 is pressed to break through the seal member 12, the peripheral portion 121 of the seal member 12 is not completely broken. Therefore, the peripheral edge portion 121 broken by the action between the lowermost end surface portion 134 corresponding to the breaking blade 133 due to the rigidity of the seal member or the tension of the residue sticks to the lowermost end surface portion 134. There is a problem that prevents the contents from falling. In order to eliminate the sticking of the seal member 12 to the breaking blade 133, it is necessary to repeatedly push and pull the seal breaking tool 13, but there is a possibility that the contents are contaminated. In addition, when it is desired to change the descending distance of the seal breaking tool 13, the stopper 14 needs to be made according to the distance, and there is a problem that the manufacturing cost is high.

  The present invention has been made to solve the above-described problems, and an object thereof is to provide a lid device that can smoothly drop contents.

  In order to achieve the above object, the present invention provides a first peripheral wall that defines a first chamber that is open at both upper and lower ends, and a peripheral end face of a lower end opening of the first peripheral wall, and the lower end opening is closed.

A tenon groove 453 is provided in the upper part of the outer peripheral surface 462 of the first peripheral wall 43 of the lid body 4, and a tenon 612 fitted into the tenon groove 453 is provided on the inner peripheral surface of the surrounding member 61.

  Next, the operation of the lid device according to the present embodiment will be described.

  As shown in FIG. 3, the mixing container before use contains a first substance (not shown) in a storage space 34 in the container body 3 and is stored in a first chamber 46 of the lid 4 of the lid device. A second substance is stored. Further, the press cutter 5 is fitted into the lid 4, and the tenon 511 of the press cutter 5 is fitted and locked in the tenon groove 451 of the lid 4, and the container body 3 is screwed by the lid device to be in an airtight state. Kept. Further, the lid 4 is covered by the stopper 6 and the container is sealed.

  At the time of use, the picking member 62 of the stopper 6 is taken and the surrounding member 61 is removed from the lid body 4 together with the cover 63. Next, the press cutter 5 is pressed so that the tenon 511 of the press cutter 5 is detached from the tenon groove 451 of the lid 4, the cutter part 523 of the lower end surface 521 of the press cutter 5 breaks through the sealing wall 44, and the tenon 511 is next. When the tenon groove 452 is fitted and stopped, the contact portion 525 contacts the unbroken portion 445 of the sealing wall 44.

  As shown in FIGS. 4 and 5, when the contact portion 525 contacts the unbroken portion 445 of the sealing wall 44, the broken portion 443 of the sealing wall 44 is lowered by the cutter portion 523 and the sealing wall 44 is not broken. The part 445 falls on the contact part 525 without being broken. At this time, the contact portion 525 hits the sealing wall 44 to such an extent that the sealing wall 44 is not broken, so that the sealing wall 44 is pushed slightly downward. In this way, when the unbroken portion 445 is pushed by the abutting portion 525 while continuing to the lower end surface of the first peripheral wall 43, the broken portion 443 of the sealing wall 44 bends downward, and between the cut portion 523 and A gap 444 is generated in the gap. Therefore, the contents of the lid device can fall from a gap that does not stick to the cut portion 523 of the fracture portion 443 of the sealing wall 44.

  In this way, the second substance stored in the first chamber 46 can fall into the first chamber 46 from the gap 444 and be mixed with the first substance stored in the container body 3. Therefore, by using this mixing container, there is no possibility of being contaminated from the outside even after opening, so that the sanitary property is not impaired, the deterioration of the mixture can be avoided, and the additive stored in the lid device can be smoothly removed. Can be dropped.

  In addition, when the lid 4 is made of a plastic material, it is not necessary to perform a separate process of attaching the sealing wall 44 to the peripheral wall 43. Therefore, the manufacturing cost can be reduced, and the possibility that the lid device is soiled can be reduced. Hygiene can be kept high. Since the sealing wall 44 and the peripheral wall 43 can be integrally formed instead of being made separately, there is no possibility that the sealing wall 44 is peeled off from the peripheral wall 43 due to expansion / contraction due to the influence of the external environment, and the sealing device 44 is not contained in the lid device. The stored contents can be stored well without leaking.

  The lid device of the present invention is useful for containers that do not impair hygiene and avoid deterioration of the mixture.
