Description

Technical Field

[0001] The invention relates to a cover unit and a container with a cover. Background Art

[0002] Conventionally, there is a container with a lid that includes a lid unit (plug body) that is detachably attached to a container body with an upper opening (for example, refer to Citation 1 listed below).

[0003] For example, the following reference 1 discloses a structure in which an operating handle is provided on a cover of an upper opening of a closing plug body, and by pressing down the operating handle, a valve body closing a fluid flow path is pressed down in an opening direction against the biasing force of a coil spring.

[0004] Patent Document 1: Japanese Patent No. 5451813

[0005] However, in the covered container described in Patent Document 1, the spout for pouring the liquid in the container body outward is exposed to the outside, so there is a possibility that dust, dirt, etc. are attached to the spout during use.

[0006] In addition, when used as a milk jug for storing milk, fresh cream, etc., the liquid flow cut-off from the spout is poor. In this case, there is a possibility that the spout, etc. may be contaminated due to liquid dripping from the spout, liquid accumulation in the spout, etc.

[0007] Therefore, in such conventional covered containers, the pouring port is easily unsanitary, and in order to keep the pouring port hygienic, the trouble of frequently cleaning the cap unit etc. is generated. In addition, when the structure of the cap unit is complicated, the careful cleaning of the cap unit is required.

[0008] On the other hand, in the case of a cover body that opens and closes the pouring port, if the liquid flowing out of the pouring port adheres to the inner surface of the cover body, there is a possibility that the liquid adhering to the cover body will scatter around when the cover body is opened, and the area around the pouring port may be soiled. Summary of the invention

DETAILED DESCRIPTION

[0052] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0053] For example, Figure 1 to Figure 5 A lidded container 100 including the lid unit 1 shown will be described.

[0054] also, Figure 1 It is a perspective view showing a state in which the lid body 9 is located at the closed position in the lid-attached container 100 including the lid unit 1 . Figure 2 This is a perspective view of the lidded container 100 when the lid 9 is in the open position, as viewed from above. Figure 3 This is a perspective view of the container with lid 100 , in which the lid 9 is located at the open position, as viewed from below. Figure 4 It is an exploded perspective view showing the structure of the container 100 with a lid. Figure 5 It is a cross-sectional view showing the structure of the container 100 with a lid.

[0055] like Figure 1 to Figure 5 As shown in FIG. 1 , a container 100 with a lid according to the present embodiment includes a lid unit 1 according to the present embodiment and a container body 2 to which the lid unit 1 is detachably mounted.

[0056] The container with a lid 100 of the present embodiment is a milk jug that can keep liquid such as milk or fresh cream contained in the container body 2 cool by using the container body 2 having a vacuum heat-insulating structure.

[0057] Specifically, in the container with a lid 100, the container body 2 is constituted by, for example, a double-structured container having a bottomed cylindrical outer container 3 and an inner container 4 made of stainless steel or the like, and the outer container 3 is formed by joining the opening edges of each other in a state where the inner container 4 is accommodated inside the outer container 3. In addition, a vacuum insulation layer 5 is provided between the outer container 3 and the inner container 4. The vacuum insulation layer 5 can be formed by, for example, blocking a degassing hole provided in the center of the bottom surface of the outer container 3 in a chamber that is decompressed (evacuated) to a high vacuum.

[0058] The container body 2 has a substantially circular bottom 2a, a cylindrical body 2b that rises substantially cylindrically from the outer periphery of the bottom 2a, and a substantially cylindrical neck 2c that is reduced in diameter on the upper side of the cylindrical body 2b. The upper end of the neck 2c opens in a circular shape when viewed from above as an upper opening 2d of the container body 2. An annular extension 2e is protrudingly provided on the inner side of the neck 2c over the entire circumference.

[0059] The lidded container 100 of the present embodiment has a generally cylindrical appearance, but the appearance of the lidded container 100 is not particularly limited and can be appropriately changed according to size, appearance design, etc. In addition, the outer peripheral surface of the container body 2 can also be painted, printed, etc.

[0060] Reference Figure 1 to Figure 7 , the structure of the cover unit 1 of this embodiment is described. In addition, Figure 6 This is a perspective view of the cover main body 7 included in the cover unit 1 as seen from above. Figure 7 This is a perspective view of the cover main body 7 included in the cover unit 1 as seen from the bottom.

[0061] In the following description, the side of the cover unit 1 where the outlet 6 described later is provided is referred to as the “front side” of the cover unit 1 , and the side opposite to the side where the outlet 6 is provided is referred to as the “rear side” of the cover unit 1 .

[0062] like Figure 1 to Figure 7As shown, the cap unit 1 of the present embodiment constitutes a plug body that closes the upper opening 2d of the container body 2. Specifically, the cap unit 1 includes a cap body 7 that closes the upper opening 2d of the container body 2 and is provided with a pouring port 6 at the upper front portion, and a cap body 9 that is rotatably mounted on the rear side of the cap body 7 via a hinge 8 and opens and closes the pouring port 6.

[0063] The cover body 7 is made of synthetic resin such as polypropylene (PP), acrylonitrile butadiene styrene (ABS), polyoxymethylene (POM), etc. The cover body 7 has a peripheral wall portion 7a formed in a substantially cylindrical shape and an upper wall portion 7b covering the upper surface of the peripheral wall portion 7a.

[0064] The cap body 7 is detachably mounted on the neck portion 2c of the container body 2 by screwing. Therefore, an internal thread portion 10 is provided on the inner peripheral surface of the peripheral wall portion 7a. On the other hand, an external thread portion 11 screwed with the internal thread portion 10 is provided on the outer peripheral surface of the neck portion 2c of the container body 2.

[0065] In addition, a handle portion 12 for the user to hold is provided on the cover body 7. The handle portion 12 is provided so as to protrude from the side surface on the rear side of the cover body 7 and extend downward.

[0066] The pouring port 6 constitutes a liquid passage for pouring the liquid in the container body 2 to the outside. Specifically, the pouring port 6 has a protrusion 6a protruding upward from the upper surface of the upper wall portion 7b (cover body 7) and forward from the side of the peripheral wall portion 7a (cover body 7), a groove portion 6b formed by cutting the upper portion of the protrusion 6a in the front-rear direction toward the front end of the protrusion 6a, an opening portion 6c opened toward the rear from the rear end of the groove portion 6b, and a recessed portion 6d obtained by making the inner surface of the cover body 7 concave from the opening portion 6c toward the rear of the protrusion 6.

[0067] In the outlet 6 of the present embodiment, the upper surface of the protruding portion 6a where at least the groove portion 6b is formed is flat. The groove portion 6b is formed to have a substantially arc shape when viewed in cross section, and cuts the central portion of the upper surface of the protruding portion 6a in the front-to-back direction. In addition, the groove portion 6b has a shape in which the width and depth gradually decrease from the rear end side toward the front end side. In addition, the groove portion 6b is inclined upward from the rear end side toward the front end side (downward from the front end side toward the rear end side).

[0068] The opening 6c is continuous with the rear end of the groove 6b and is formed into a substantially arc shape when viewed in cross section, and the upper portion of the groove 6b is formed to be substantially linear when viewed in cross section in a manner that closes the upper portion of the groove 6b. In addition, the opening 6c faces the inner side of the cover body 7 and opens in a plane orthogonal to the extension direction (front-rear direction) of the groove 6b.

[0069] The recess 6d has a shape in which the depth gradually increases from the rear end side toward the opening 6c located at the front end side on the lower surface of the upper wall portion 7b (the inner surface of the cover body 7). Figure 7 As shown, the recessed portion 6d is formed to expand in a substantially arc shape in a plan view from the flat lower surface (bottom surface of the recessed portion 6d) of the protruding portion 6a continuous with the opening portion 6c toward the rear side.

[0070] A vent 13 for introducing external air into the container body 2 is provided at the upper portion of the cover body 7. The vent 13 is formed by a circular hole portion located at the rear side of the pouring port 6 of the upper wall portion 7b (cover body 7) and penetrating the upper wall portion 7b in the thickness direction.

[0071] A circular ring wall 7c is provided on the inner side of the cover body 7 so as to protrude from the lower surface of the upper wall portion 7b. Figure 5 and Figure 7 As shown, the annular wall 7c is provided to protrude concentrically with the peripheral wall 7a at a position continuous with the opening 6c. That is, the opening 6c is provided to penetrate the annular wall 7c in the front-rear direction. The vent 13 is provided at a position overlapping with the rear end side of the annular wall 7c.

[0072] A water stop packing 14 is detachably mounted inside the cap body 7. The water stop packing 14 is a sealing member for sealing the cap body 7 and the container body 2, and is made of heat-resistant rubber such as silicone rubber or an elastic member such as an elastomer.

[0073] The waterproof gasket 14 has a stepped shape along the lower surface of the upper wall portion 7b, the outer peripheral surface of the annular wall 7c, and the lower end surface, and is formed in a circular ring shape as a whole. The waterproof gasket 14 is embedded between the peripheral wall portion 7a and the annular wall 7c in a state of contact with the lower surface of the upper wall portion 7b, the outer peripheral surface of the annular wall 7c, and the lower end surface.

[0074] On the other hand, the waterproof gasket 14 can be removed from the inner side of the cover body 7 by elastically deforming (stretching) itself. Thus, the waterproof gasket 14 and the cover body 7 can be cleaned separately, and the space between the waterproof gasket 14 and the cover body 7 can be kept clean.

[0075] In addition, an elastic flange portion 14a protruding along the entire circumference in the direction of the diameter expansion is provided on the outer peripheral surface of the water stop gasket 14. When the cover body 7 is installed on the container body 2, the elastic flange portion 14a of the water stop gasket 14 is elastically deformed and is in close contact with the upper end of the neck mouth portion 2c over the entire circumference. As a result, the cover body 7 and the container body 2 can be sealed in a liquid-tight manner (waterproof).

[0076] The cover body 9 is made of a synthetic resin such as polypropylene (PP), acrylonitrile-butadiene-styrene (ABS), or polyoxymethylene (POM). The cover body 9 includes a top wall portion 9a covering the pouring port 6 and the upper portion of the cover body 7, and a peripheral wall portion 9b protruding downward from the periphery of the top wall portion 9a. The peripheral wall portion 9b is formed to cover the front end side of the pouring port 6 after the cover body 9 closes the pouring port 6, and is in contact with the upper wall portion 7b of the cover body 7 and is coplanar with the peripheral wall portion 7a.

[0077] The lid 9 is attached to be rotatable in the vertical direction via a hinge 8 provided on the upper portion of the handle 12 (lid body 7). The lid 9 is biased in a direction to close the pouring port 6 by its own weight.

[0078] The cover 9 has a rod 15 protruding along the upper part of the handle 12 at a position behind the hinge 8. The cover 9 can be rotated in a direction to open the spout 6 by pressing the rod 15 downward while the handle 12 is held.

[0079] The cover 9 has a protrusion 16 protruding from the lower surface of the top wall 9a at a position opposite to the groove 6b of the outlet 6. The protrusion 16 has a shape extending in the front-to-back direction and gradually decreasing in height from the rear end side toward the front end side in accordance with the shape of the groove 6b. In addition, the front end of the protrusion 16 is connected to the peripheral wall 9b.

[0080] In the cover unit 1 of this embodiment having the above structure, after the cover body 9 closes the outlet 6, the front end of the protrusion 16 abuts against the bottom surface of the groove 6b, and the lower surface of the top wall 9a abuts against the flat upper surface of the protrusion 6a.

[0081] Thus, for example, even if the container body 2 is tilted forward in order to pour the liquid without pressing the operating lever 15 by mistake, and the liquid flowing out of the pouring port 6 adheres to the inner surface of the cover 9 corresponding to the flat surface of the protruding portion 6a, the liquid adhering to the cover 9 via the protruding portion 16 can be returned to the pouring port 6 side. In addition, by making the lower surface of the top wall 9a contact with the flat upper surface of the protruding portion 6a, the liquid adhering to the inner surface of the cover 9 can be prevented from leaking from the pouring port 6. Therefore, when the cover 9 is opened, the liquid adhering to the cover 9 can be prevented from scattering around and contaminating the area around the pouring port 6.

[0082] In addition, in the cover unit 1 of this embodiment, starting from the state where the cover body 9 opens the pouring outlet 6, the container body 2 can be tilted forward while the liquid in the container body 2 is easily poured out from the pouring outlet 6, and the liquid flow interruption from the pouring outlet 6 after pouring out the liquid is improved.

[0083] Specifically, in the pouring port 6, when the liquid in the container body 2 is poured out from the opening 6c through the groove 6b, the recess 6d functions as a liquid storage portion, and introduces external air from the vent 13 into the interior of the container body 2. Thus, it is possible to prevent air from flowing in from the opening 6c, and to smoothly pour the liquid temporarily accumulated in the recess 6d from the opening 6c to the groove 6b. That is, during the period when the liquid flows out from the opening 6c, the opening 6c is blocked by the liquid, so it is possible to prevent air from flowing in from the opening 6c.

[0084] On the other hand, in the pouring port 6, the width and depth of the groove 6b gradually decrease from the rear end side to the front end side, thereby improving the liquid flow cut-off from the front end of the groove 6b after pouring the liquid. In addition, the groove 6b is inclined downward from the front end side to the rear end side, so that the liquid flowing along the groove 6b can be quickly returned to the container body 2 through the opening 6c.

[0085] Therefore, in the cap unit 1 of this embodiment, the spout 6 can be prevented from being contaminated by liquid dripping from the spout 6 or liquid accumulating in the spout 6, and the spout 6 can be kept hygienic. In addition, the trouble of frequently cleaning the cap unit 1 can be avoided.

[0086] In the cap unit 1 of the present embodiment, the simple structure of the cap main body 7 and the cap body 9 can improve the cleanability thereof. Therefore, in the lidded container 100 of the present embodiment, by including such a cap unit 1, the usability can be further improved.

[0087] In addition, the present invention is not necessarily limited to the above-described embodiment, and various modifications can be made without departing from the gist of the present invention.

[0088] For example, in the above-mentioned embodiment, the container with lid 100 applied to the above-mentioned milk jug is exemplified, but the present invention can be widely applied to containers with lids including a lid unit detachably attached to the neck of the container body.

[0089] In the above embodiment, the container 100 with a lid that maintains the cold-keeping function by the container body 2 having the above-mentioned vacuum insulation structure is exemplified, but the present invention can also be applied to a container with a lid having a container body without a vacuum insulation structure.
