[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a cap such as a detergent container.

[0002]

[Prior art]

 As a conventional cap, there is one described in Japanese Utility Model Laid-Open No. 62-200567. In this conventional technology, in a cap in which the upper lid is openable and closable via a pin-shaped hinge part in the cap body, (a) the cap body has a top surface part with a spout and a spout around the top surface part. The mounting cylinder provided, the outer cylinder integrally provided around the top surface of the mounting cylinder, the push operation part integrally provided at a position facing the hinge part of the outer cylinder, and the push operation offset of the top surface (B) The lid opening force is applied by contacting the stopper inserted into the spout and the push operation piece via the engaging slope on the upper lid. (C) It is mounted on the hinge part and urges the upper lid in the opening direction. And a coil spring that operates.

Therefore, in this conventional cap, the engaging protrusion of the cap body and the engaging portion of the upper lid are engaged by pushing up the pushed upper portion of the upper lid by the pressing force applied to the push operation piece. The upper lid can be opened with one touch by removing the spring.

[0004]

[Problems to be solved by the device]

 However, the conventional techniques have the following problems. The coil spring has a strong biasing force, and the top lid opens abruptly. Further, since the coil spring is generally made of metal, it is easily rusted, and there is a risk that the rust will be mixed into the contents in the container poured from the spout of the cap body.

The upper lid is maintained closed with respect to the cap main body by the engagement between the engagement protrusion on the cap main body side and the engagement portion on the upper lid side provided near the push operation piece. For this reason, the pushing-up angle of the top lid by the push operation is small, and the lid can be opened relatively easily, but the degree of plugging engagement between the spout and the stopper is zero or a positive fitting that creates a gap, and the pouring when the lid is closed. Poor sealing of the outlet. Therefore, there is a risk of leakage in contents with low viscosity.

Penetration notches are provided on both sides of the push operation piece in the outer cylinder of the cap body. For this reason, (a) Dust enters the outer cylinder from the notch, and electrostatically stains dust around the notch, and (b) Drip from the spout enters the outer cylinder, and this liquid drip from the bottom of the notch. (C) The design provided on the front surface of the outer tube cannot be continuous because the design is applied to the front surface of the outer tube, and the label provided on the front surface of the outer tube cannot be spread on both sides of the cut. Impair the appearance of the cap.

The present invention allows the top lid to be opened gently at an appropriate speed, prevents the contents from being rusted, and improves the sealing property of the spout when the lid is closed. The purpose of the present invention is to improve the appearance and the like of the cap without the operation portion for opening the lid being accompanied by a through cut in the outer cylinder of the cap.

[0008]

[Means for Solving the Problems]

 According to the present invention as set forth in claim 1, in a cap in which an upper lid is openable and closable via a hinge on the cap body, the cap body is integrally formed around a top surface portion having a spout and a spout of the top surface portion. The outer cylinder, the outer cylinder integrally provided around the top cylinder at the top surface, and the push operation portion integrally provided at a position facing the hinge of the outer cylinder. Both sides of the push operation part in are made thin parts, and the upper lid is in contact with the push operation part via the engagement slope with the sealing engagement part that can be engaged with the spout in a sealed state to maintain the closed state. In particular, it has a pushed piece to which a lid opening force is applied, and a rubber-like elastic body is attached to at least one of the cap body and the upper lid in the vicinity of the hinge, and the rubber-like elastic body is pressed when the upper lid is closed. Top of the cap body It is obtained by the so configured to elastically deformed between the.

According to a second aspect of the present invention, in addition to the first aspect of the present invention, the pushed upper piece of the upper lid is backed up to the cap body under the pressing force of the push operation portion. It is configured so as to be.

[0010]

[Action]

 According to the present invention as set forth in claim 1, the following effects are obtained. The rubber-like elastic body interposed between the cap body and the upper lid is configured to elastically deform when the upper lid is closed, so when the closed state of the cap body and the upper lid is released, this elastic deformation The elastic restoring force of the rubber-like elastic body opens the upper lid. This restoring force is not excessive like the coil spring, and the top cover can be gently opened at an appropriate speed.

[0011] Further, since the member that gives the restoring force to the upper lid is a rubber-like elastic body and is not made of metal such as a coil spring, it does not corrode, and rust is not mixed into the contents poured from the spout of the cap body. It will never happen.

The upper lid is maintained closed with respect to the cap body by engaging the spout on the cap body side and the sealing engagement portion on the upper lid side in a sealed state. Therefore, the fitting degree between the spout and the sealing engagement portion is a negative fitting (no gap is generated), and the sealing performance when the lid is closed can be improved. Therefore, even if the content has low viscosity, no leakage occurs.

By providing thin portions on both sides of the push operation portion in the outer cylinder of the cap body, the push operation portion can be pushed and deformed toward the pushed upper piece of the upper lid.

That is, the thin portion is extended and deformed by the push operation force applied to the push operation portion, and the push operation portion can be deformed by pushing. Further, since the push operation portion itself is thicker than the thin portions on both sides, the push operation portion is stably displaced without buckling due to the push operation force and securely engages with the pushed upper piece to securely push the pushed upper piece. Apply the lid opening force.

Here, since the outer cylinder of the cap body has a thin portion for pushing deformation of the push operation portion and does not have a through cut, (a) dust is allowed to enter the outer cylinder through the cut. (B) Even if the liquid dripping from the spout enters the outer cylinder, the liquid drips from the bottom of the notch and stains the outer surface of the container and the label. (C) The design applied to the front surface of the outer tube cannot be continuous because it is divided by the notch, or the label provided on the front surface of the outer tube cannot be stretched on both sides of the notch and spoils the appearance of the cap. Instead, the design and label on the front of the outer tube can be laid across both sides of the thin wall without any discomfort, improving the appearance of the cap.

According to the present invention as set forth in claim 2, there is the following action. The pushed upper piece of the upper lid is back-up supported by the cap body under the pressing force of the push operation section, so that the pushed upper piece of the upper lid is pinched between the push operation section and the cap body. It will be able to be squeezed upward (toward the lid). Therefore, the amount of push operation applied to the push operation part is effectively converted to the lid opening direction, and even if the fitting length between the spout and the sealing engagement part is large, a light push operation can be performed reliably. You can open the lid. That is, it is possible to improve the operability of the lid opening while increasing the fitting length between the spout and the sealing engagement portion to enhance the sealing performance when the lid is closed.

Specifically, an M-shaped groove 29 is provided on the surface of the front surface of the outer cylinder 24, and the portions corresponding to the respective pieces of the groove 29 are the thin portions 27, 27, 28, 28. The central portion sandwiched between the members 27 is a push operation unit 25.

The base of the outer cylinder 24 is fitted around the stepped outer surface 11A of the container body 11, and the base of the push operation portion 25 provided on the outer cylinder 24 is backed up to the stepped outer surface 11A. . As a result, the push operating portion 25 is supported by the container main body 11 like a cantilever lever, and the push operating force applied to the push operating portion 25 ensures that the upper portion of the push operating portion 25 is securely held as shown by the chain line in FIG. It is elastically deformable by pushing.

The upper lid 15 is bowl-shaped and has a protrusion-shaped sealing engagement portion 31 at the center of the inner surface thereof, which can engage with the spout 21 of the cap body 13 in a sealed state to maintain the closed state. . 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 push operation portion 25 through the engaging inclined surfaces 25A and 32A on the inner surface on the front surface side of the cap 12.

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

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 portion 25.

A fitting groove 41 is formed on the top surface 22 of the cap body 13 in the vicinity of the hinge 14, and a rubber elastic body 42 is fitted into the fitting groove 41. The rubber-like elastic body 42 is composed of rubber or elastomer (for example, a methyl vinyl-based raw rubber synthesized with KE951U manufactured by Shin-Etsu Chemical Co., Ltd. as a compound and C-8 manufactured by the same company as a vulcanizing agent). It Further, the rubber-like elastic body 42 has a substantially U-shaped cross section as shown in FIG. 2A, and one end portion 43 is fitted into the fitting groove 41. The other end 44 of the rubber-like elastic body 42 is formed in a tapered wedge shape, and its tip is in contact with the inner surface of the upper lid 15 so that it can be compressed and bent.

That is, as shown in FIGS. 2A to 2C, in the process of closing the upper lid 15, the tip of the other end 44 of the rubber-like elastic body 42 abuts against the inner surface of the upper lid 15 and is pressed. It By this pressing, the other end portion 44 of the rubber-like elastic body 42 bends inward, the rubber-like elastic body 42 bends and deforms the A portion 42A and the B portion 42B, and when the upper lid 15 is closed, the other end portion 44 is The rubber elastic body 42 is compressed between the inner surface 42C of the elastic body 42 and the inner surface of the upper lid 15 so as to be folded.

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 body 42 is subjected to elastic deformation such as bending and compression between the cap body 13 and the upper lid 15.

(2) When the cap 12 is opened, the container body 11 is grasped with one hand, and the push operation portion 25 of the cap body 13 is pushed with, for example, the thumb. As a result, the engagement slope 25A of the push operation portion 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 in the opening direction around the hinge 14, and as a result, the sealing engagement portion of the upper lid 15. 31 is disengaged 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 elastic body 42 in the elastically deformed state of (1) acts as the opening force of the upper lid 15 and the upper lid 15 Open the lid.

The operation of this embodiment will be described below. Since the rubber-like elastic body 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 this elastically deformed rubber-like elastic body 42 opens the upper lid 15. This restoring force is not excessive like the coil spring, and can cause the upper lid 15 to gently open at an appropriate speed.

Further, the member that gives the restoring force to the upper lid 15 is the rubber-like elastic body 42, which is not made of metal like the coil spring and therefore does not corrode and is poured out from the spout 21 of the cap body 13. No rust is mixed in with the product.

Further, since the one end portion 43 of the rubber-like elastic body 42 is fitted in the fitting groove 41 of the cap body 13 and the adhesive agent is not used, the adhesive agent does not flow out to the contents in the container. Moreover, the phenomenon that the adhesive is deteriorated by the contents does not occur.

The closure of the upper lid 15 with respect to the cap body 13 is maintained by engaging the spout 21 on the cap body 13 side and the sealing engagement portion 31 on the upper lid 15 side in a sealed state. Therefore, the fitting degree between the spout 21 and the sealing engagement portion 31 is a negative fitting (no gap is generated), and the sealing performance at the time of closing the lid can be improved. Therefore, even if the content has low viscosity, no leakage occurs.

By providing the thin portions 27 and 28 on both sides of the push operation portion 25 in the outer cylinder 24 of the cap body 13, the push operation portion 25 can be pushed and deformed toward the pushed upper piece 32 of the upper lid 15.

That is, the thin-walled portions 27 and 28 are extended and deformed by the push operation force applied to the push operation portion 25, and the push operation portion 25 can be pushed and deformed. Since the push operation portion 25 itself is thicker than the thin portions 27 and 28 on both sides, the push operation portion 25 is stably displaced without buckling due to the push operation force and securely engages with the pushed upper piece 32. The lid opening force is surely applied to the pushed upper piece 32.

Here, since the outer cylinder 24 of the cap body 13 includes the thin portions 27 and 28 for pushing deformation of the push operation portion 25 and does not have a through cut, (a) dust is cut from the cut. It does not enter the outer cylinder 24, and does not cause dust contamination around the cut. (B) Even if the dripping from the spout 21 enters the outer cylinder 24, this dripping flows out from the lower part of the cut. (C) The design on the front of the outer tube 24 cannot be continuous because it is cut off by the notch, or the label provided on the front of the outer tube 24 is on both sides of the notch. The design and label on the front of the outer tube 24 can be stretched over both sides of the thin-walled parts 27, 28 without causing any discomfort and the appearance of the cap 12 can be improved. Possible To.

The pushed upper piece 32 of the upper lid 15 is backed up and supported by the cap main body 13 under the pressing force of the push operating portion 25, so that the pushed upper piece 32 of the upper lid 15 is pushed by the push operating portion. It is pinched between the cap 25 and the cap body 13 and is squeezed upward (toward the lid). Therefore, the push operation amount applied to the push operation portion 25 is effectively converted to the lid opening direction, and even when the fitting length between the spout 21 and the sealing engagement portion 31 is large, the light push operation is performed. The lid can be opened securely with. 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.
