Set to be smaller than the fitting force at the time. By setting in this way, when removing the cover cap 4 from the container 2, the sealing plug body 3 can be shifted to the cover cap 4 side, and the sealing plug body can be moved by removing the cover cap 4 from the container 2. 3 can be reliably removed from the spout 10.

  Further, when an impact force is applied to the cover cap 4 by a drop impact or the like with the cover cap 4 mounted on the container 2, the impact force is absorbed by the buffer portion 3 </ b> C having a U-shaped cross section, and the sealing plug 3 It is possible to avoid applying an impact force directly to the sealing portion 3A. As a result, even when subjected to a drop impact or the like, the sealing of the spout 10 by the sealing plug 3 can be maintained, and liquid overflow at the time of dropping or falling can be prevented.

  2-5 has shown the other structural example of the container with a cover cap which concerns on embodiment of this invention. In these examples, the cap structure for the container 2 includes a three-piece structure including an inner plug 5, a sealing plug body 3, and a cover cap 4. The container 2 has a bottle shape having a mouth part 2A, a shoulder part 2B, and a body part 2C. By plugging the inner plug 5 into the mouth part 2A of the container 2, the container 2 is narrower than the opening of the mouth part 2A. The spout 10 is provided.

  The inner plug 5 includes an opening insertion portion 5A to be inserted into the opening of the mouth portion 2A in the container 2, a stopper fitting portion 5B to be fitted to a fitted portion 2E provided outside the mouth portion 2A, and an outer peripheral flange. 5C is provided. Further, the inner plug 5 has an opening closing portion 5D provided inside the opening insertion portion 5A, and a dispensing cylinder portion 5E is provided at the center of the opening closing portion 5D. A narrow outlet 10 is provided from the opening of the portion 2A.

In the example shown in FIGS. 2 and 3, or in the example shown in FIGS. 4 and 5, the container 2 and the cover cap 4 are made common, and the configurations of the sealing plug body 3 and the inner plug 5 are changed. The example shown in FIGS. 2 and 3 is an example in which the diameter of the spout 10 can be changed by changing the shapes of the sealing plug 4 and the inner plug 5, and the spout of the example shown in FIG. 10 is narrower than the spout 10 in the example shown in FIG.
When the spout 10 is made narrow as shown in FIG. 3, in order to share the cover cap 4, the interval of the U-shaped cross section of the buffer portion 3C is widened (right side in FIG. 3), or the buffer portion 3C is cross sectioned. The shape can be changed to a W shape (left side in FIG. 3) by changing the shape to provide a buffering action while giving rigidity.

  In the cover cap 4 in the example shown in FIGS. 2 and 3, the mounting portion 4A on the cover cap 4 side is the female screw portion 4A1, and the mounted portion 2D on the container 2 side is the male screw portion 2D1. In the cover cap 4 in the example shown in FIGS. 4 and 5, the mounting portion 4A on the cover cap side is the fitting convex portion 4A2, and the mounted portion 2D on the container 2 side is the fitting concave portion 2D2.

  The cover cap 4 in FIGS. 2 to 5 includes a curl ring portion 4D that hangs down from the top surface 4B. The curl ring portion 4D is provided so as to surround the mouth portion 2A of the container 2, and a lower end bent portion 4D1 bent outward along the shoulder portion 2B of the container 2 is provided at the lower end. In the curl ring portion 4D, a plurality of guide ribs 4D2 projecting toward the side portion of the inner plug 5 are extended downward from the top surface 4B.

  By providing such a curl ring part 4D, when the cover cap 4 is attached to the container 2 with the inner stopper 5 plugged, the container 2 is placed in the curl ring part 4D by the lower end bent part 4D1 of the curl ring part 4D. The mouth portion 2A and the inner plug 5 are guided, and the cover cap 4 can be prevented from being obliquely fogged. When the inner plug 5 is housed in the curl ring portion 4D, the guide rib 4D2 in the curl ring portion 4D protrudes toward the side portion of the inner plug 5, so that the posture of the cover cap 4 is properly maintained. In addition, the cover cap 4 is accurately positioned with respect to the container shaft.

  After the cover cap 4 is attached to the container 2, the lower end bent part 4D1 of the curl ring part 4D and the shoulder part 2B of the container 2 are separated from each other in normal times. On the other hand, when a drop impact or the like is applied to the cover cap 4, the lower end bent portion 4D1 hits the shoulder 2B of the container 2 due to deformation of the cover cap 4 and the container 2, and the curl ring portion 4D is It functions as a support and can avoid or alleviate the collision between the top surface 4B of the cover cap 4 and the sealing portion 3A of the sealing plug 3. This also maintains the sealing performance of the spout 10 when an impact is applied.

  Furthermore, the cover cap 4 includes a support ring portion 4E that hangs down from the top surface 4B. The support ring portion 4E is formed so that the lower end thereof is in contact with the upper surface of the opening closing portion 5D of the inner plug 5 when the cover cap 4 is attached to the container 2. The collision between 4B and the sealing portion 3A of the sealing plug 3 is avoided or alleviated. Further, by providing the cover cap 4 with the curl ring portion 4D and the support ring portion 4E, the rigidity of the cover cap 4 itself is enhanced.

  The example shown in FIGS. 2 to 5 includes a sealing plug 3 that is separate from the cover cap 4, and the sealing plug 3 is an outer peripheral portion 3 </ b> B that is fitted to the fitting portion 4 </ b> C of the cover cap 4. Since the buffer portion 3C is provided between the sealing portion 3A and the sealing portion 3A, when an impact force such as a drop impact is applied to the cover cap 4, it is possible to avoid that the impact force is directly transmitted to the sealing portion 3A. . As a result, it is possible to prevent liquid overflow when it falls or falls.

  In the example shown in FIGS. 2 to 4, a gap G is formed between the sealing plug 3 and the top surface 4 </ b> B of the cover cap 4 with the cover cap 4 attached to the container 2. The height of the support ring portion 4E depending from the top surface 4B of the cover cap 4 is set such that the gap G is formed in a state where the lower end thereof is in contact with the upper surface of the inner plug 5. By providing such a gap G, an impact transmitted from the top surface 4B of the cover cap 4 to the sealing portion 3A of the sealing plug 3 can be avoided or reduced.

  On the other hand, in the example shown in FIG. 5, the outer peripheral portion 3 </ b> B (the outer peripheral portion upper surface 3 </ b> B <b> 2) of the sealing plug body 3 comes into contact with the top surface 4 </ b> B of the cover cap 4 with the cover cap 4 attached to the container 2. Is set to According to this, since the top surface 4B of the cover cap 4 presses the outer peripheral surface 3B2 of the sealing plug body 3, the sealing cap body 3 is securely attached to the spout 10 by attaching the cover cap 4 to the container 2. Can be done. Further, when the cover cap 4 receives an impact, the sealing cap body 3 can be prevented from being lifted by pressing by the top surface 4B of the cover cap 4, and further, between the outer peripheral portion 3B and the sealing portion 3A. By providing the buffer portion 3C, it is possible to avoid or reduce the transmission of an impact to the sealing portion 3A.

  The usage method of the container 1 with a cover cap shown in FIGS. 2-5 is demonstrated by FIG. The container 2 is filled with the contents from the opening of the mouth portion 2A. After filling the container 2 with the contents, as shown in FIG. 6A, the inner plug 5 in which the spout 10 is sealed with the sealing plug body 3 is plugged into the mouth 2 </ b> A of the container 5.

  In this state, the plug portion 3P of the sealing plug body 3 is inserted into the spout 10 provided in the extraction tube portion 5E of the inner plug 5, and the sealing portion 3A is fitted to the upper portion of the extraction tube portion 5E. The sealing portion 3A is in close contact with the inner surface, the upper surface, and the outer surface of the upper portion of the dispensing cylinder portion 5E. Further, the fitting side portion 12 of the inner plug 5 is fitted inside the buffer portion 3 </ b> C of the sealing plug body 3. By transporting the container 2 in such a state, the container 2 filled with the contents can be transported while preventing overflow due to the liquid contents jumping up from the spout 10.

  Thereafter, as shown in FIG. 6B, the cover cap 4 is attached to the container 2 so that the sealing plug 3 and the inner plug 5 are accommodated in the curl ring portion 4D. Thereby, the fitting portion 4 </ b> C of the cover cap 4 is fitted to the outer peripheral portion 3 </ b> B of the sealing plug body 3. In this state, the product is distributed through film packaging.

  As shown in FIG. 6C, the user who purchased the product removes the cover cap 4 from the container 2 and tilts the container 2 to pour out the contents from the spout 10. At this time, the fitting force between the inner plug 5 and the sealing plug body 3 in the fitting side portion 12 is set to be smaller than the fitting force between the cover cap 4 and the sealing plug body 3 in the fitting portion 4C. In one operation of removing the cover cap 4 from the container 2, the sealing plug 3 is moved to the cover cap 4 side, and the spout 10 is opened. When the cover cap 4 is attached to the container 2 again, the spout 10 is resealed with the sealing plug 3.

  As described above, the cover cap-equipped container 1 according to the embodiment of the present invention has a cap structure in which the sealing plug body 3 can be fitted and detached integrally by the cover cap 4, and the sealing portion in the sealing plug body 3 is used. By providing the buffer portion 3C having a U-shaped cross section between 3A and the outer peripheral portion 3B, it is possible to avoid or reduce transmission of impact applied to the cover cap 4 at the time of dropping or falling to the sealing portion 3A. it can. Thereby, the overflow of the liquid at the time of fall of the container 1 with a cover cap and a fall can be prevented.

  Since the sealing plug 3 is a separate member from the cover cap 4, immediately after the container 2 is filled with the liquid content, the contents are kept in a state where the spout 10 is sealed with the sealing plug 3. Can be transported. Thereby, when the container 2 filled with the contents is transported, overflow due to the liquid contents jumping up from the spout 10 can be prevented.

  After that, when the cover cap 4 is attached to the container 2, the fitting force with which the cover cap 4 fits the sealing plug body 3 is set larger than the fitting force with which the sealing plug body 3 fits the inner plug 5. The cover cap 4 can be attached and detached integrally with the sealing plug body 3. For this reason, the opening operation when opening the spout 10 repeatedly can be simplified, and the spout 10 can be reliably sealed by the sealing portion 3A of the sealing plug 3 when the cover cap 4 is remounted. .
