Description

  The present invention relates to a technique for suppressing an increase in internal pressure caused by a lid, which is a container with a lid for storing contents in a closed space by attaching a lid to the container.

  As represented by hair dyeing agents, when different materials are mixed in a container, the materials may react to generate gas. In this case, when the internal pressure of the container rises by covering the container, the cover body may fly and the contents may be scattered.

  On the other hand, in the conventional technology, a rise in internal pressure between the container and the lid is suppressed by adopting a gas permeable member as a part of the lid.

  However, in the conventional technique, a gas permeable member must be used separately. Moreover, when such a gas permeable member is used, it is necessary to separately use a member for holding it. For this reason, there is room for improvement in productivity and cost with the increase in the number of parts.

  An object of the present invention is to provide a novel container with a lid that can prevent air pressure from increasing while ensuring airtightness without using a gas permeable member.

As shown in the figure, the lid body 2 is formed with a dome-shaped bulging portion 2c that is curved so as to protrude upward.

Reference numeral 3 denotes a stopper that enables the lid 2 to be opened and closed by one-side opening. 3a has a lower part 3b that fits with the lower end 1f of the flange 1a, and an upper part 3c that wraps around from the lower part 3b to the upper end 2f of the outer peripheral edge 2a has the flange 1a and the outer peripheral edge 2a together with the lower part 3b. It is a holding part to hold. The holding | maintenance part 3a is formed in the semicircular arc shape extended along the edge of the flange 1a and the outer periphery 2a. Thus, the lid 2, allowing single swing from the opening A _1. Further, since the holding portion 3a holds the flange 1a and the outer peripheral edge 2a between the lower part 3b and the upper part 3c, the stopper 3 is guided by the flange 1a and the outer peripheral edge 2a and is indicated by the arrow in FIG. As shown, it can be attached while sliding along the flange 1a and the outer peripheral edge 2a from the lateral direction.

  Reference numeral 3d denotes a cover that is disposed on the upper side of the lid 2 and contacts the bulging portion 2c of the lid 2. The cover 3d is integrally connected through the holding portion 3a and the step portion 3e. The step portion 3e has a trapezoidal cross-sectional shape with a flat surface portion 3f extending in a semicircular arc shape along the edge of the outer peripheral edge 2a as an upper base, and is connected to the upper portion 3c via the outward inclined portion 3g, It is connected to the cover 3d via the inwardly inclined portion 3h. Thereby, when the cover body 2 opens partly, the step part 3e allows the cover 3d to be deformed along with the opening, and gives the cover 3d a restoring force against the deformation of the cover 3d.

  According to this embodiment, when the pressure between the container 1 and the lid 2 is increased, the lid 2 is easily bent around the bulging portion 2c as shown in FIG. As shown in (b), the lid body 2 is opened one side. Thereby, the pressure between the container 1 and the cover body 2 can be reduced because the gas between the container 1 and the cover body 2 escapes.

  Further, when the pressure between the container 1 and the lid body 2 is reduced, the cover 3d is connected to the holding portion 3a via the step portion 3e, so that the cover 3d deformed by the single opening of the lid body 2 Thus, an urging force for returning to the initial position shown in FIG. Thereby, when the pressure between the container 1 and the lid body 2 decreases, the lid body 1 is automatically closed as shown in FIG.

  In addition, according to the present embodiment, since the gas venting is performed by opening the lid 2 one by one, it is not necessary to separately use a member having gas permeability. In addition, the present embodiment can be configured with a small number of parts such as three parts of the container 1, the lid 2, and the stopper 3.

  Therefore, according to this embodiment, it is possible to provide a novel container with a lid in which an increase in internal pressure is suppressed while ensuring airtightness.

  Further, as in this embodiment, if the bulging portion 2c that is curved so as to protrude upward is provided at the center of the lid body 2, the lid body 2 can be easily bent around the bulging portion 2c. 2 can be easily realized.

  FIG. 5 shows a second embodiment of the present invention, in which finger pads 3i hang down from the lower portion 3b on both the left and right sides of the holding portion 3a. A plurality of anti-slip ribs 3j are formed on the finger rest 3i. In this case, it becomes easy to attach while sliding along the flange 1a and the outer peripheral edge 2a from the lateral direction.

Incidentally, a stopper 3 of the present embodiment, as shown in FIG. 3 (b), the cover 3d, opening A ₂ for fitting the bulging portion 2c of the lid 2 is formed. If the opening A ₂ is formed in the cover 3d, the stopper 3 can be made difficult to come off from the lid 2. However, according to the present invention, as shown in FIG. 3 (c), without forming openings A _2, by a one piece, by providing the bulging portion 3d ₀ to mating the bulging portion 2c Can do.

  6 to 8 show a third embodiment of the present invention. In this embodiment, the inwardly inclined part 3h that connects the flat part 3f and the cover 3d is formed in a stepwise cross-sectional shape so that the step part 3e rises toward the container center axis O. Also in this case, as shown in FIG. 8, when the lid body 2 is opened, the step portion 3e allows the cover 3d to be deformed along with the opening, and provides a restoring force against the deformation of the cover 3d. Give to 3d.

The cover 3d according to the present embodiment, without fitting A ₂ for fitting the bulging portion 2c is formed in contact with the distal end of the bulging portion 2c.

Furthermore, FIGS. 9-11 is the 4th form of this invention. This embodiment is a modification of the third embodiment. By forming two parallel slits S in the cover 3d, the cover base 3d ₁ connecting the cover 3d to the inwardly inclined surface 3h, and the cover base 3d ₁ and a tongue piece 3d ₂ that can be deformed and restored to a bent line H that is a connecting portion to ₁ . Accordingly, the tongue piece 3d ₂ is deformed up and down with respect to the cover base 3d ₁ with the fold line H as a base point. Therefore, the cover 3d furthermore, at the tongue portion 3d _2, while permitting deformation accompanying the opening of the single cover body 2, the restoring force is applied to deformation of the cover 3d.

  By forming the slit S in the cover 3d as in the present embodiment, the cover 2d is allowed to be deformed as the cover 2 is opened, and the cover 3d is given a restoring force against the deformation of the cover 3d. The body 2 can be opened by a smooth motion.

In this embodiment, the lower end 3g _(e) of the outwardly inclined surface 3g of the holding portion 3a is inclined upward at an angle θ ₁ toward the tip of the cover 3d as shown in FIG. 11 (a). It is configured as follows. In this way, if the lower end 3g _(e) of the outwardly inclined surface 3g is given a weak inclination, the holding portion 3a holds the outer peripheral edge 2a extending over the flange 1a only at the rear, so that the lid 2 is opened in one piece. The operation of the cover 2d during the operation becomes better.

Further, in the present embodiment, as shown in FIG. 11 (b), the upper surface of the lid body 2 is configured to be inclined downward at an angle θ ₂ toward the outer side in the radial direction. In this case, since the lid body 2 is easily deformed, a good one-side opening can be realized.

  Furthermore, in this embodiment, as shown in FIG. 6 (a) with a part of the stopper 3 cut away and enlarged, the claw portion 3p is provided inside the side wall portion 3k that connects the lower portion 3b and the upper portion 3c. And is configured to be detachable by hooking the claw portion 3p on the side surface of the outer peripheral edge 2a of the lid. In this case, unless a constant external force is applied to the stopper 3, it can be prevented from coming off by sliding from the lateral direction.

  12 and 13 show a fifth embodiment of the present invention. The stopper 3 according to the present embodiment has a lower portion 3b whose holding portion 3a is fitted to the lower end 1f of the flange 1a, and the upper end of the lower portion 3b beyond the upper end 2f of the outer peripheral edge 2a of the lid 2. The middle leg part 3m hanging from the upper part 3c holds the flange 1a and the outer peripheral edge 2a together with the lower part 3b.

  As shown in FIG. 12 (a), the holding portions 3a are arranged at the left and right and the rear three locations in a semicircular arc-shaped region extending along the edges of the flange 1a and the outer peripheral edge 2a. Further, the middle foot portion 3m is formed in a semicircular arc shape extending along the edges of the flange 1a and the outer peripheral edge 2a as shown by a broken line in FIG. As a result, the lid 2 can be opened on one side.

  Also in this embodiment, when the pressure between the container 1 and the lid body 2 is increased, the lid body 2 is opened one side. Thereby, the pressure between the container 1 and the cover body 2 can be reduced because the gas between the container 1 and the cover body 2 escapes.

  Further, when the pressure between the container 1 and the lid body 2 is reduced, the cover 3d is formed by extending the upper part 3b where the middle leg part 3m hangs forward, so that the lid 2 can be opened one by one. The deformed cover 3d generates an urging force that causes the cover 3d to return to the initial position. Thereby, when the pressure between the container 1 and the lid body 2 decreases, the lid body 2 is automatically closed as in the first embodiment.

  In addition, in this embodiment as well, the gas venting is performed by opening the lid 2 one by one, so there is no need to separately use a member having gas permeability. Moreover, this embodiment can also be configured with a small number of parts such as the container 1, the lid 2, and the stopper 3.

  Therefore, according to this embodiment, it is possible to suppress an increase in internal pressure while ensuring airtightness.

  Also in this embodiment, the holding portion 3a holds the flange 1a and the outer peripheral edge 2a between the lower part 3b and the upper part 3c, so that the stopper 3 is guided by the flange 1a and the outer peripheral edge 2a. As shown by the arrow 1, it can be attached while sliding along the flange 1 a and the outer peripheral edge 2 a from the lateral direction, but it can also be configured as a claw portion by adjusting the length of the lower portion 3 b. In this case, since the lower part 3b is detachably locked by being caught on the outer peripheral edge 2a, the stopper 3 can be attached and detached.

14 and 15 show a sixth embodiment of the present invention. This embodiment is a modification of the fifth embodiment, and the lower end 3m _(e) of the middle foot portion 3m is inclined upward at an angle θ ₃ toward the tip of the cover 3d as shown in FIG. 13 (a). Is configured to do. Thus, if the lower end 3m _(e) is given a weak inclination, the holding portion 3a holds the outer peripheral edge 2a extending over the flange 1a only at the rear, so that the cover 2d of the cover 2d when the cover body 2 is partially opened is used. Works better.

Further, in this embodiment, two parallel slits S are formed in the cover 3d formed by extending the upper part 3b, so that the cover 3d is connected to the holding base 3d ₁ and the bent line H as a base. And a tongue piece 3d ₂ that can be deformed and restored. Thus, the cover 3d furthermore, at the tongue portion 3d _2, together with the deformation accompanying the opening of the single cover body 2 is permitted, resiliency is applied to deformation of the cover 3d.

  The above description shows the preferred embodiment of the present invention, but various design changes can be made according to the application. For example, the holding portion 3a may be disposed at least rearward in a semicircular arc-shaped region extending along the edges of the flange 1a and the outer peripheral edge 2a so that the lid body 2 can be opened on one side. That's fine. Moreover, each structure employ | adopted for each form can be combined with each other suitably.
