Japanese Patent No. 3397502 JP 9-37839 A JP-A-11-56456

  However, the combination of the screw-type lids is complicated in structure, increases the manufacturing cost, and makes the container heavier or bulky, making it less convenient than the usual one. There's a problem. In addition, the type in which the packing is in close contact must open the cover from a state in which the packing is in close contact with the back surface of the cover or the inside of the annular groove. There is a problem.

  The present invention has been made in view of such circumstances, and is an excellent compact that has a simple structure, can sufficiently ensure the airtightness of the cosmetic container, and can be easily opened and closed. The purpose is to provide containers.

In order to achieve the above object, the present invention provides a compact container in which a container body provided with a cosmetic container for housing cosmetics and a lid body that covers the upper surface opening of the container body are connected in an openable and closable manner. An annular groove is formed in the outer periphery of the cosmetic container of the container body, and an annular elastic packing having an upper portion protruding upward from the opening surface of the annular groove and a lower portion fixed in the groove is mounted in the annular groove. and, in the closed state of the above lid, said annular elastic gasket is pushed into the annular groove in a state in which forcibly contracted was vertically, Rutotomoni top of that is biased pressed against the lower surface of the lid that The peripheral surface portion is pressed and urged against the side wall of the annular groove to keep the inside of the cosmetic container in an airtight state, and when the lid is opened, the annular elastic packing is restored, and the upper portion pushes the lid upward to make up the makeup. Reduces airtightness in the material storage A compact container which is in earthenware pots and first aspect.

In the present invention, a container main body provided with a cosmetic container for storing cosmetics and a lid for covering the upper surface opening of the container main body are connected in an openable and closable manner, so that at least the cosmetic container of the container main body is stored. The inner lid that covers the portion is a compact container that is freely opened and closed between the container body and the lid body, and an annular groove is formed on the outer periphery of the cosmetic container of the container body. An annular elastic packing with the upper part protruding upward from the opening surface of the annular groove and the lower part fixed in the groove is mounted inside, and when the inner lid is closed, the annular elastic packing is forcibly contracted in the vertical direction. is pushed into the annular groove while being urged pressed against the lower surface upper portion of the inner lid of that Rutotomoni maintaining its peripheral surface is biased pressed against the side walls of the annular groove cosmetic receptacle in an airtight state, during the opening operation of the inner lid, the ring Elastic gasket is restored, and a compact container upper portion thereof has a inner lid to reduce the airtightness of pushed up within the cosmetic receiving portion second aspect.

  Of these, the third aspect is a compact container in which the annular elastic packing is formed in a bellows shape that expands and contracts in the vertical direction.

  That is, the compact container according to the present invention not only enhances the airtightness maintaining function at the time of close contact by simply bringing the annular elastic packing provided on the outer periphery of the cosmetic container into close contact with the side surface of the lid body. When the cover is opened in a state of being compressed and deformed, the upper part of the annular elastic packing is popped out of the groove by the restoring force so as to push up the cover and reduce its airtightness. ing. Therefore, this can open the lid with a light force even though a sufficient hermetic holding force can be obtained with the lid closed, and is easy to use. Moreover, even if there is some variation in the dimension of the portion that presses the annular elastic packing, there is an advantage that the adhesion with the annular elastic packing is not impaired.

  Among the compact containers, when the annular elastic packing is formed in a bellows shape that expands and contracts in the vertical direction, it is difficult to lose its shape even after repeated expansion and contraction, and is excellent in resilience. Can be used in good condition.

  Next, the best mode for carrying out the present invention will be described.

  FIG. 1 is a partially exploded perspective view showing a compact container which is the best embodiment of the present invention. In the figure, reference numeral 1 denotes a container body having a substantially oval shape in plan view, which accommodates a concave portion (hereinafter referred to as “cosmetic material accommodating portion”) 2 for accommodating cosmetics, and cosmetic accessories such as cosmetic puffs and cosmetic brushes. The recessed part 3 for doing is formed in the state located in a line with right and left. Moreover, the notch part 4 for hinge connection is formed in the rear-end part.

  On the other hand, 5 is a lid that covers the upper surface of the container body 1, and a hinge portion 6 that is formed to protrude from the rear end of the container body 1 enters the notch 4 on the container body 1 side. The container body 1 is openably and closably connected via hinge pins 7 (see FIG. 2) that are inserted from the left and right ends of the container body 1 respectively. 30 is a mirror.

  Further, downward ridges 8 are formed on the peripheral edge of the lower surface of the lid 5, so that the ridges 8 come into contact with the peripheral edge of the upper surface of the container body 1 with the lid 5 closed. (See FIG. 3). In addition, an engagement piece 11 that engages with the protruding piece 10 provided on the container body 1 side is provided at the center of the lower surface of the front end portion of the lid body 5. The body 5 is opened and closed. In addition, the state which closed the cover body 5 is shown in FIG.

  An annular groove 20 is formed on the outer periphery of the cosmetic container 2 of the container body 1 concentrically with the cosmetic container 2, and an annular elastic packing 21 is fitted therein. And the protrusion 22 is formed in the annular part of the lower surface of the said cover body 5 facing the annular elastic packing 21 in the said annular groove 20, The state which closed the cover body 5 as shown in FIG. Thus, the protrusion 22 pushes the annular elastic packing 21 into the annular groove 20 and comes into pressure contact with the upper surface thereof. Note that reference numeral 23 denotes a metal plate accommodated in the cosmetic material accommodating unit 2 and is filled with the cosmetic material 24.

  More specifically, as shown in FIG. 4, the annular elastic packing 21 is formed in a bellows shape that expands and contracts in the vertical direction, and the lower portion is forcibly fitted and fixed to the inner wall 20 a of the annular groove 20. Yes. When the lid 5 is closed, the upper surface 21 a of the annular elastic packing 21 is pressed downward by the ridge 22 on the lid 5 side and is in close contact with the lower surface of the ridge 22 horizontally. Further, the angles of the bellows bent portions 21b and 21c are forcibly contracted in the vertical direction and repelled, and the upper surface 21a is pressed against the lower surface of the ridge 22 to be urged.

  Therefore, when the engagement between the projecting piece 10 and the engaging piece 11 is released, as shown in FIG. 5, as the annular elastic packing 21 is restored, the upper surface 21a pushes up the lower surface of the projecting ridge 22 and remains horizontal. The upper surface 21a is tilted, the contact with the protrusion 22 is released, and the airtightness is released. Thereby, the cover body 5 can be opened easily.

  Thus, according to the said structure, although sufficient sealing holding force is obtained in the state which closed the cover body 5, the cover body 5 can be opened with a light force, and it is convenient. Even if the height of the protrusion 22 that presses the annular elastic packing 21 varies, or the lid 5 itself is somewhat distorted, the downward pressing force on the annular elastic packing 21 varies. Since the upward pressing biasing force by the annular elastic packing 21 is large, there is an advantage that the adhesion with the lid 5 is not impaired.

  In the above example, the annular protrusion 22 is formed on the lower surface of the lid 5 and the annular elastic packing 21 in the annular groove 20 is pressed on the lower surface. However, the protrusion 22 is not necessarily provided. The annular elastic packing 21 may be pressed directly on the lower surface of the lid body 5 without being formed. Therefore, the lower surface of the protrusion 22 is also an aspect of “the lower surface of the lid 5”.

  Further, in the above example, the annular elastic packing 21 is fixed by forcibly fitting the lower part thereof into the annular groove 20. However, the fixing of the annular elastic packing 21 is not limited to the forced fitting. In addition, the annular groove 20 may be bonded to the bottom surface or side surface with an adhesive or the like.

  Furthermore, in the present invention, the configuration of the portion that hinge-connects the container body 1 and the lid 5 is not limited to the above example, and any hinge structure conventionally used for opening and closing compact containers can be used. There is no problem.

  Further, as shown in FIG. 6, the present invention provides a compact container in which an inner lid 40 that covers at least the cosmetic container 2 is provided between the container body 1 and the lid 5 so as to be freely opened and closed. Can be applied. In that case, the annular elastic packing 21 is pushed into the annular groove 20 by the protrusions 41 provided on the lower surface of the inner lid 40 (or directly on the lower surface), and the lid 5 is closed via the inner lid 40. Is pressed downward to keep the inside of the cosmetic container 2 in an airtight state. In order to keep the inner lid 40 closed when the lid 5 is closed, any inner lid such as a protrusion for pressing the upper surface of the inner lid 40 is provided on the lower surface of the lid 5. A holding means is required (not shown).

  Similarly to the above embodiment, when the lid 5 is opened, the inner lid 40 is pushed upward with the restoration of the annular elastic packing 21 and the airtightness is easily released. The effect of.

  Furthermore, the ring-shaped elastic packing 22 used in the present invention is suitable for the bellows-like shape, which is not easily deformed even if it is repeatedly expanded and contracted, but is not limited to the bellows-like shape, and when the lid 5 is closed, As long as the upper part is pressed and urged against the lower surface of the lid body 5 so that the lid body can be pushed upward when the lid body 5 is opened, any object can be used.

  However, since the upper surface pressed against the lower surface of the lid 5 is lifted while the lid 5 is in close contact with the lower surface of the lid 5 during the opening operation, the airtightness is difficult to be released. It must be set so that the airtightness is reduced by changing the inclination of the plate or reducing the contact area.

For example, as shown in FIG. 7A, the peripheral surface is curved, and when the lid 5 is closed, the upper surface thereof is in close contact with the lower surface of the lid 5 as shown in the drawing. However, when the lid 5 is opened, as shown by a chain line, there is one that extends in an oblique direction and the angle of the upper surface becomes non-horizontal (modified example of the annular elastic packing used in the present invention) . Further, as shown in FIG. 7B, the upper surface is raised in an arc shape in cross section, and when the lid 5 is closed, the upper surface is crushed to the lower surface of the lid 5 as shown in the figure. However, when the lid 5 is opened, the raised portion is restored as shown by the chain line (a reference example of the annular elastic packing) .

  In addition, the material of the annular elastic packing 21 must have both airtightness and elasticity, and in particular, a material made of polyester elastomer having a high rebound resilience exerts a strong pushing force at the time of restoration. It is suitable for a thin and compact container.
