In the container 10, a cap 12 is attached to the opening of the container body 11, and when the cap 12 is in an open state, the container body 11 is squeezed (squeezed) so that the contents such as a detergent are poured. It is possible to go out.

The cap 12 can open and close the upper lid 15 via a pin 14 (coupling portion) integrally formed with the cap body 13.

The cap body 13 includes a top surface portion 22 having a spout 21, a mounting tube 23 integrally provided around the spout 21 of the top surface portion 22, and a mounting tube 23 around the top surface portion 22. The outer cylinder 24 is provided. Further, the cap body 13 has upper cover engaging recesses 24A formed on both sides of the outer cylinder 24 on the rear surface side of the cap 12, and left and right protruding from both side parts of the outer cylinder 24 toward the inside of the recess 24A. It has a pin 14 of. Further, the cap body 13 has a push operation piece 25 that is formed by cutting out at a position facing the pin 14 of the outer cylinder 24 on the front surface side of the cap 12. The mounting tube 23 has a round tubular shape and has an internal thread 26. The internal thread 26 is screwed onto an external thread provided in the opening of the container body 11 so that the cap 12 can be attached to the container body 11. . The outer cylinder 24 is a rectangular cylinder that fits the outer diameter of the container body 11.

The upper lid 15 has a bowl shape, and is provided with a coupling convex portion 30 to be inserted into the upper lid coupling concave portion 24 A of the cap body 13 on the rear surface side of the cap 12, and on both side portions of the convex portion 30. It has a notched guide groove 30A into which the pin 14 provided in the recess 24A of the cap body 13 is introduced, and a support hole 30B continuous with the guide groove 30A. Then, the upper lid 15 fits the coupling convex portion 30 into the coupling concave portion 24A with the guide groove 30A of the coupling convex portion 30 aligned with the pin 14 of the upper lid coupling concave portion 24A. As a result, both side portions of the cap body 13 around the coupling recess 24A are elastically expanded slightly by the coupling projection 30 of the upper lid 15 to guide the pin 14 from the guide groove 30A to the support hole 30B side. When the pin 14 is engaged with the support hole 30B, the expansion described above is released to allow the cap body 13 and the upper lid 15 to be openably and closably coupled around the pin 14. Further, the upper lid 15 has a protrusion-shaped sealing engagement portion 31 which can be engaged with the spout 21 of the cap body 13 in a sealed state to maintain the closed state at the center of the inner surface thereof. Further, the upper lid 15 has a pushed upper piece 32 which is provided with an opening force by being brought into contact with the inner surface of the front side of the cap 12 with the push operation piece 25 via the respective engaging slopes 25A and 32A. .

In the closed state of the cap 12, the push operation piece 25 is erected on the same plane as the outer cylinder 24 of the cap body 13, and the upper edge portion of the push operation piece 25 is provided with the upper lid 15. The lower edge of the front surface is abutted against each other, and the pushed upper piece 32 is provided with a gap between the engaging inclined surface 25A of the push operation piece 25 of the cap body 13 and the outer peripheral surface of the mounting cylinder 23. The engagement slope 32A is set at the position. When the cap 12 is opened, the engagement slope 32A of the pushed upper piece 32 of the upper lid 15 is pressed by the engagement slope 25A of the push operation piece 25, and the mounting cylinder 23 of the cap body 13 is pressed. Will be backed up and supported on the outer peripheral surface.

In the present invention, the pushed upper piece 32 of the upper lid 15 does not necessarily need to be backed up and supported by the cap body 13 under the pressing force of the push operation piece 25.

Now, as shown in FIGS. 1, 2B, and 3B, a fitting groove 41 is provided at the central portion in the width direction of the outer peripheral portion of the coupling convex portion 30 of the upper lid 15. A rubber-like elastic ring 42 is attached to the fitting groove 41 in a press-fitted state. The rubber-like elastic ring 42 is composed of rubber, elastomer or the like (for example, a methyl vinyl raw rubber compounded with KE951U manufactured by Shin-Etsu Chemical Co., Ltd. as a compound and C-8 manufactured by the same company as a vulcanizing agent). . The rubber-like elastic ring 42 has an O-ring shape, a part of which is press-fitted into the fitting groove 41, and the rest is projected on the surface of the coupling convex portion 30. When the upper lid 15 is closed, the rubber-like elastic ring 42 is pressed against the top surface portion 22 on the cap body 13 side while being backed up by the fitting groove 41 on the upper lid 15 side, and the diametrical direction thereof. Is given a compressive elastic deformation.

Further, in the cap 12, as shown in FIGS. 1B, 2 and 3, protruding thin stoppers 51 are provided on both sides in the width direction of the outer peripheral portion of the coupling convex portion 30 of the upper lid 15. It is integrally molded. In the process of opening and closing the upper lid 15, the thin stopper 51 is elastically deformed so as to exceed the stopper engaging portion 52 formed by the wall surface around the coupling recess 24A of the cap body 13, and the upper lid 15 is opened. By engaging with the stopper engaging portion 52 in the closing direction, the opening angle of the upper lid 15 (opening angle in FIGS. 1A and 2A) can be maintained.

Therefore, the cap 12 is opened and closed as follows. (1) When the cap 12 is closed, the sealing engagement portion 31 of the upper lid 15 engages with the spout 21 of the cap body 13 in a sealed state, and the closed state is maintained. At this time, the rubber-like elastic ring 42 is given a compressive elastic deformation between the cap body 13 and the upper lid 15 (FIG. 3).

(2) When the cap 12 is opened, the container body 11 is grasped with one hand, and the push operation piece 25 of the cap body 13 is pushed with the thumb, for example. As a result, the engagement slope 25A of the push operation piece 25 presses the engagement slope 32A of the pushed upper piece 32 provided on the upper lid 15, and the pushed upper piece 32 is attached to the outer periphery of the mounting cylinder 23 of the cap body 13. As a result of pinching with the surface and squeezing up the pushed upper piece 32 in the upward direction (opening direction), the upper lid 15 is pushed up around the pin 14 in the opening direction, and by extension, the sealing engagement of the upper lid 15 occurs. The part 31 is detached from the spout 21 of the cap body 13. Simultaneously with the disengagement of the sealing engagement portion 31 and the spout 21, the elastic restoring force of the rubber-like elastic ring 42 in the elastically deformed state of the above (1) acts as the opening force of the upper lid 15 to open the upper lid 15. Open the lid (Fig. 2).

The above-described opened state of the upper lid 15 is maintained by engaging the thin stopper 51 on the upper lid 15 side with the stopper engaging portion 52 on the cap body 13 side as shown in FIG. 2A. .

The operation of this embodiment will be described below. Since the rubber elastic ring 42 interposed between the cap body 13 and the upper lid 15 is configured to elastically deform when the upper lid 15 is closed, the closed state of the cap body 13 and the upper lid 15 is released. Then, the elastic restoring force of the elastically deformed rubber-like elastic ring 42 opens the upper lid 15. This restoring force is not excessive like the coil spring, and the upper lid 15 can be gently opened at an appropriate speed.

When the rubber-like elastic ring 42 is elastically deformed when the upper lid 15 is closed, the deformation due to the compression is evenly distributed over the entire circumference thereof, and the permanent strain can be reduced.

The member that gives a restoring force to the upper lid 15 is the rubber-like elastic ring 42, which is not made of metal like a coil spring and therefore does not corrode, and the contents poured out from the spout 21 of the cap body 13 It does not cause rust to be mixed in.

Further, since the one end portion 43 of the rubber-like elastic ring 42 is fitted into the fitting groove 41 of the cap body 13 and no adhesive or the like is used, the adhesive may flow out to the contents in the container. Moreover, the phenomenon that the adhesive is deteriorated by the contents does not occur.

As the rubber-like elastic ring 42, a simple O-ring can be used, which is inexpensive. Further, the rubber-like elastic ring 42 is incorporated only by fitting it into the fitting groove 41 provided in the cap body 13 or the upper lid 15, and the presence or absence of the incorporation can be seen from the outside, so that an assembly error occurs. Nonetheless, productivity can be improved.

With a simple configuration in which the thin stopper 51 is provided on the side of the upper lid 15 and the stopper engaging portion 52 is provided on the side of the cap body 13, the opening angle of the upper lid 15 can be maintained.

In the cap 12, the pushed upper piece 32 of the upper lid 15 is backed up and supported by the cap body 13 under the pressing force of the push operation piece 25, whereby the pushed upper piece 32 of the upper lid 15 is covered. The push-up piece 32 is pinched between the push-up piece 25 and the cap body 13 of the push-operation piece 25 and is squeezed upward (toward the lid). Therefore, the amount of push operation applied to the push operation piece 25 is effectively converted in the lid opening direction, and even when the fitting length between the spout 21 and the sealing engagement portion 31 is large, a light push operation is performed. The lid can be opened securely by pressing the button. That is, the fitting length between the spout 21 and the sealing engagement portion 31 is increased to improve the sealing performance when the lid is closed, and the operability of the lid opening can be improved.

The embodiment of the present invention has been described in detail above with reference to the drawings. However, the specific configuration of the present invention is not limited to this embodiment, and changes in design without departing from the gist of the present invention are possible. Even if it exists, it is included in the present invention. For example, the cap body and the upper lid may be openably and closably coupled to each other via an integral hinge. Further, the lid closing means of the upper lid is not limited to the one constituted by the spout of the cap body and the sealing engagement portion of the upper lid, and may be constituted by other portions.

Further, in the practice of the present invention, the rubber-like elastic ring may be attached to at least one of the cap body and the upper lid, may be attached to the side of the cap body, or may be attached to the cap body and the upper lid. It may be attached to both.
