Description

Container with lid

The present invention relates to a container with a cover.

A container with a lid is known that adopts a structure in which an opening provided on a container body is sealed with an outer lid and an inner lid (for example, refer to the following patent document 1).

Specifically, such a container with a lid comprises: a container body having an opening at the upper end; an inner lid which fills the color of the opening when embedded into the inner side of the container body from the opening; a waterproof gasket which seals the container body and the inner lid when mounted on the inner lid; and an outer lid which is screwed to the container body when covering the opening from the outside. In addition, the container with a lid is configured so that the plugging gasket (embolism body) provided on the outer lid blocks the air hole (gas flow hole) provided on the inner lid.

When the outer cover of such a container with a cover is installed on the container body, the inner cover can be restricted from moving upward by the closing gasket abutting against the inner cover. In addition, when the outer cover of the container with a cover is removed from the container body, the blockage of the air hole by the closing gasket will be released. In this way, even if the pressure in the container body is low (becomes negative pressure), when the outer cover is removed from the container body, external gas can be introduced through the air hole, so that the air pressure in the container body becomes the same as the atmospheric pressure. Therefore, the inner cover will not be pulled to the inside of the container body, and the inner cover can be easily removed from the inside of the container body.

As described above, according to the present invention, a container with a cover is provided, which is not only low-cost and has a simple structure, but also can remove the cover from the container body in a safe and easy manner in response to the pressure change of the container body.

The following describes the embodiments of the present invention in detail with reference to the drawings.

(First implementation form)

First, a first embodiment of the present invention, for example a container 1A with a cover as shown in FIGS. 1 to 8 , will be described.

1 is an exploded perspective view showing the structure of a first embodiment of a container with a lid 1A of the present invention; FIG. 2 is a cross-sectional view showing a state in which a lid 3 is mounted to a container body 2 of the container with a lid 1A; FIG. 3 is an enlarged cross-sectional view showing a portion A of the container with a lid 1A circled in FIG. 2; and FIG. 4 is a perspective view showing a state in which a waterproof pad 4 is mounted on the inner side of the lid 3. FIG5 is a plan view showing the inner side of the cover 3; FIG6 is an enlarged plan view showing the cover 3 of the circled portion B in FIG5; FIG7 is an enlarged three-dimensional view showing the cover 3 of the circled portion B in FIG5; FIG8 is an enlarged cross-sectional view of the covered container 1A showing the circled portion A in FIG2 for illustrating the deformation state of the waterproof pad 4 when the pressure in the container body 2 is low.

As shown in FIGS. 1 to 3 , the covered container 1A of this embodiment includes a container body 2 having an opening at an upper end 2a, a cover 3 for opening and closing the upper end opening 2b of the container body 2, and a waterproof pad 4 for sealing the container body 2 and the cover 3.

The container body 2 is formed of a heat-resistant resin such as polypropylene (PP) and has: a bottom 2c, which is substantially circular; a body 2d, which is vertically formed from the outer periphery of the bottom 2c in a cylindrical shape; and a head and neck portion 2e, which is provided on the upper side of the body 2d in a substantially cylindrical shape with a slope. In addition, an upper end opening portion 2b with a circular opening is formed at the upper end of the head and neck portion 2e to serve as an upper end portion 2a of the container body 2.

1 to 5, the cover body 3 is formed of a heat-resistant resin such as polypropylene (PP), and has a peripheral wall portion 3a formed substantially in a cylindrical shape, and a top wall portion 3b for blocking an upper section of the peripheral wall portion 3a.

The lid 3 can be detachably mounted to the container body 2 by screwing. Therefore, the outer peripheral surface of the head and neck portion 2e (container body 2) is provided with a male threaded portion 5. On the other hand, the inner peripheral surface of the peripheral wall portion 3a (lid 3) opposite to the outer peripheral surface of the head and neck portion 2e (container body 2) is provided with a female threaded portion 6 that can be screwed with the male threaded portion 5.

Furthermore, a plurality of protrusions 7 for preventing slipping are provided on the outer peripheral surface of the peripheral wall portion 3a (cover body 3). The protrusions 7 extend in the vertical direction and are arranged at equal intervals in the circumferential direction of the peripheral wall portion 3a.

The waterproof gasket 4 is formed of a heat-resistant, substantially annular elastic member such as silicone rubber. The waterproof gasket 4 is detachably mounted on the inner side of the cover body 3 by fitting.

Therefore, the cover body 3 has: a rib wall 8, which is opposite to the inner peripheral surface of the peripheral wall portion 3a and protrudes in a circular ring shape from the lower surface of the top wall portion 3b; and a groove 9, which is formed in a circular ring shape between the peripheral wall portion 3a and the rib wall 8.

On the other hand, the waterproof pad 4 has: a first elastic portion 4a, which can be embedded in the groove 9; a second elastic portion 4b, which extends downward from one end of the first elastic portion 4a and is provided with an embedding recess 10 for the rib wall 8 to be embedded; an elastic flange portion 4c, which is opposite to the first elastic portion 4a and protrudes from the outer circumference of the second elastic portion 4b; and a third elastic portion 4d, which is located at the opposite side (inner circumference) of the first elastic portion 4a with the embedding recess 10 clamped.

The waterproof pad 4 can be removed from the cover 3, so that it can be washed separately from the cover 3, and the hygiene between the waterproof pad 4 and the cover 3 can be maintained. In addition, the waterproof pad 4 is provided with a removal piece 11 protruding from the third elastic portion 4d toward the inside, and the removal piece 11 is used to make it easier to remove from the inside of the cover 3.

In the lidded container 1A of this embodiment, when the lid 3 is installed on the head and neck portion 2e of the container body 2, that is, when the lid 3 blocks the upper end opening 2b of the container body 2, the first elastic portion 4a of the waterproof pad 4 is elastically deformed so that the waterproof pad 4 is tightly fitted to the bottom surface of the groove 9 of the lid 3 in a whole circle, and the elastic flange portion 4c of the waterproof pad 4 is elastically deformed so that the waterproof pad 4 is tightly fitted to the upper end portion 2a of the container body 2 in a whole circle, thereby enabling the container body 2 and the lid 3 to be sealed through the waterproof pad 4.

However, in the lidded container 1A of the present embodiment, as shown in FIGS. 3 , 6 and 7 , the lid body 3 has: a first gas circulation recess 12 formed by a portion of the bottom surface of the groove 9 being recessed in a radial direction; and a second gas circulation recess 13 formed by a portion of the rib wall 8 being recessed in a vertical direction at a position overlapping with the first gas circulation recess 12 in a circumferential direction.

The width of the first gas circulation recess 12 is wider than that of the second gas circulation recess 13. In addition, the second gas circulation recess 13 is continuously provided with the first gas circulation recess 12 at a position where it overlaps with the first gas circulation recess 12 in the circumferential direction. That is, the second gas circulation recess 13 is continuously provided from the front end (lower end) to the base end (upper end) of the rib wall 8.

The first gas circulation recess 12 and the second gas circulation recess 13 are respectively arranged at multiple positions in the circumferential direction (two positions in this embodiment). At this time, the first gas circulation recess 12 and the second gas circulation recess 13 are preferably arranged at equal intervals in the circumferential direction of the groove 9. However, the first gas circulation recess 12 and the second gas circulation recess 13 can also be configured to be arranged at least one position in the circumferential direction of the groove 9.

In the lidded container 1A of the present embodiment having the above-described structure, when the pressure in the container body 2 increases, the lid 31 is lifted up.

Thereby, a part of the first elastic part 4a (waterproof gasket 4) of the cover 3 which is tightly fitted with the groove 9 will separate from the groove 9, and the pressure in the container body 2 can be released to the outside through the first gas flow recess 12, the second gas flow recess 13 and a part of the interlocking recess 10, so that the pressure in the container body 2 will become the same as the outside (atmospheric pressure).

Therefore, the lidded container 1A of this embodiment will not be affected when the pressure in the container body 2 increases (becomes a positive pressure state), and the lid body 3 can be easily and safely removed from the container body 2 by releasing the screwing of the male threaded portion 5 and the female threaded portion 6 between the container body 2 and the lid body 3.

The situation where the pressure in the container body 2 rises (becomes a positive pressure state) can be exemplified by the situation where a high-temperature content is placed in the container body 2, or the situation where the content in the container body 2 is rotten and gas is generated.

On the other hand, in the lidded container 1A of the present embodiment, when the pressure in the container body 2 is low, a portion of the first elastic portion 4a, the second elastic portion 4b and the third elastic portion 4d (waterproof pad 4) will be squeezed toward the container body 2 while being elastically deformed, as shown in FIG. 8 .

Thereby, the external air can be introduced into the interior of the container body 2 through the first gas circulation recess 12, the second gas circulation recess 13 and a part of the interlocking recess 10, so the pressure inside the container body 2 will become the same as the external pressure (atmospheric pressure).

Therefore, when the pressure in the container body 2 is low (becoming a negative pressure state), the lidded container 1A of this embodiment will not be affected, and the screwing of the male threaded portion 5 and the female threaded portion 6 between the container body 2 and the lid body 3 is released, and the lid body 3 can be easily and safely removed from the container body 2.

The situation where the pressure in the container body 2 decreases (becomes a negative pressure state) can be exemplified by the situation where a high-temperature content is placed in the container body 2 and the content is cooled.

As described above, the lidded container 1A of this embodiment has a low-cost and simple structure, and the lid 3 can be easily and safely removed from the container body 2 in response to changes in pressure within the container body 2.

The covered container 1A of this embodiment is not limited to the above-mentioned structure, and the first gas flow recess 12 and the second gas flow recess 13 may be made into a discontinuous structure as shown in FIG. 9 or FIG. 10 .

That is, the second gas flow recess 13 shown in Fig. 9 and Fig. 10 is continuously recessed from the front end (lower end) of the rib wall 8 to the upper middle portion. Thereby, the first gas flow recess 12 and the second gas flow recess 13 are separated.

In addition, in the covered container 1A of the present embodiment, the first gas circulation recess 12 and the second gas circulation recess 13 may not be located at overlapping positions in the circumferential direction, but, for example, as shown in FIG. 11 , one of them may be moved to a position of 90° in the circumferential direction.

With such a structure, when the pressure in the container body 2 increases (becoming a positive pressure state) or when the pressure in the container body 2 decreases (becoming a negative pressure state), it will not be affected. The screwing of the male threaded portion 5 and the female threaded portion 6 between the container body 2 and the cover body 3 can be released to easily and safely remove the cover body 3 from the container body 2.

(Second implementation form)

Next, a container 1B with a cover as shown in, for example, FIG. 12 to FIG. 19 will be described as a second embodiment of the present invention.

Among them, Figure 12 is an exploded three-dimensional diagram of the structure of the covered container 1B of the second embodiment of the present invention; Figure 13 is a cross-sectional view showing the state of the cover 3 being installed to the container body of the covered container 1B; Figure 14 is an enlarged cross-sectional view of the covered container 1B showing the circled portion C in Figure 13; Figure 15 is a plan view showing the inner side of the cover 3. FIG. 16 is a plan view showing the structure of the waterproof pad 4; FIG. 17 is an enlarged plan view showing the waterproof pad 4 of the circled portion D in FIG. 16; FIG. 18 is an enlarged three-dimensional view showing the waterproof pad 4 of the circled portion D in FIG. 16; and FIG. 19 is a cross-sectional view of the covered container 1B showing the circled portion C in FIG. 13 for explaining the deformation state of the waterproof pad 4 when the pressure in the container body is low. In addition, in the following description, the description of the parts equivalent to the above-mentioned covered container 1A is omitted and the same symbols are given in the drawings.

The container 1B with a lid of this embodiment is structured such that the first gas circulation recess 12 and the second gas circulation recess 13 provided on the side of the lid body 3 in the structure of the container 1A with a lid are provided on the side of the waterproof pad 4 .

Specifically, in the container with a lid 1B, the lid body 3 omits the first gas circulation recess 12 and the second gas circulation recess 13 as shown in FIGS. 12 to 19 .

On the other hand, the waterproof pad 4 includes: a first gas circulation recess 14, which is formed by recessing a portion of the surface (upper surface) of the first elastic portion 4a opposite to the bottom surface of the groove 9 in a radial direction; and a second gas circulation recess 15, which is formed by recessing a portion of the surface (outer peripheral surface of the engaging recess 10) of the second elastic portion 4b opposite to the rib wall 8 in a vertical direction at a position overlapping with the first gas circulation recess 12 in the circumferential direction.

The first gas circulation recess 14 is formed to be wider than the second gas circulation recess 15. In addition, the second gas circulation recess 15 is continuous with the first gas circulation recess 14 at a position where the second gas circulation recess 15 overlaps with the first gas circulation recess 14 in the circumferential direction.

The first gas circulation recess 14 and the second gas circulation recess 15 are respectively arranged at multiple positions (two positions in this embodiment) in the circumferential direction. At this time, the first gas circulation recess 14 and the second gas circulation recess 15 are preferably arranged at equal intervals in the circumferential direction of the waterproof pad 4. On the other hand, the first gas circulation recess 14 and the second gas circulation recess 15 can also be arranged at least at one position in the circumferential direction of the waterproof pad 4.

In the lidded container 1B of the present embodiment having the above-described structure, when the pressure in the container body 2 increases, the lid 3 is lifted upward.

Thereby, a part of the first elastic part 4a (waterproof gasket 4) of the cover 3 which is tightly fitted with the groove 9 will separate from the groove 9, and the pressure in the container body 2 can be released to the outside through the first gas flow recess 12, the second gas flow recess 13 and a part of the interlocking recess 10, so that the pressure in the container body 2 will become the same as the outside (atmospheric pressure).

Therefore, the lidded container 1B of this embodiment will not be affected when the pressure in the container body 2 increases (becomes a positive pressure state), and the lid body 3 can be easily and safely removed from the container body 2 by releasing the screwing of the male threaded portion 5 and the female threaded portion 6 between the container body 2 and the lid body 3.

On the other hand, in the lidded container 1B of the present embodiment, when the pressure in the container body 2 is low, a portion of the first elastic portion 4a, the second elastic portion 4b and the third elastic portion 4d (waterproof pad 4) will be squeezed toward the container body 2 while being elastically deformed, as shown in FIG. 19 .

Thereby, the external air can be introduced into the interior of the container body 2 through the first gas circulation recess 14, the second gas circulation recess 15 and a part of the interlocking recess 10, so the pressure inside the container body 2 will become the same as the external pressure (atmospheric pressure).

Therefore, when the pressure in the container body 2 is low (becoming a negative pressure state), the lidded container 1B of this embodiment will not be affected, and the screwing of the male threaded portion 5 and the female threaded portion 6 between the container body 2 and the lid body 3 is released, and the lid body 3 can be easily and safely removed from the container body 2.

As described above, the lidded container 1B of this embodiment has a low-cost and simple structure, and the lid 3 can be easily and safely removed from the container body 2 in response to changes in pressure within the container body 2.

However, the covered container 1B of this embodiment is not limited to the above structure, and the first gas circulation recess 14 and the second gas circulation recess 15 may be made into a discontinuous structure as shown in FIG. 9 or FIG. 10 .

In addition, in the covered container 1B of the present embodiment, the first gas circulation recess 14 and the second gas circulation recess 15 may not be located at overlapping positions in the circumferential direction, but, for example, as shown in FIG. 11 , one of them may be moved to a position 90° in the circumferential direction.

With such a structure, when the pressure in the container body 2 increases (becoming a positive pressure state) or when the pressure in the container body 2 decreases (becoming a negative pressure state), it will not be affected. The screwing of the male threaded portion 5 and the female threaded portion 6 between the container body 2 and the cover body 3 can be released to easily and safely remove the cover body 3 from the container body 2.

However, the present invention is not limited to the above-mentioned embodiments, and various modifications can be made without departing from the scope of the present invention.

For example, the appearance of the covered container to which the present invention is applied is not limited, and can be appropriately modified in terms of size or design. In addition, the present invention can also be applied to a covered container having a vacuum insulation structure and thus having a cold-keeping (or heat-keeping) function.
