Description

  The present invention relates to a cosmetic container in which a middle dish is accommodated via a middle dish housing case excellent in impact resistance.

  Conventionally, in the case of so-called compact type cosmetic containers that contain foundations, eye colors, lip colors, etc., if they are accidentally dropped or applied to other objects during transportation, display sales, or customer use, the impact In order to prevent the occurrence of such troubles, various types of containers with improved impact resistance have been proposed. .

  For example, the present applicant has developed and put into practical use a cosmetic container as shown in FIG. 6 (see Patent Document 1). This container includes a container main body 3 that accommodates an inner dish 2 (a metal dish or a resin dish) filled with cosmetics 1 and a lid 4 that covers the container main body 3. The container main body 3 is connected to the outer peripheral wall 5. A shallow dish-shaped inner box 6 that accommodates the inner tray 2, and a connecting wall part 7 that connects the upper end of the outer peripheral wall 5 and the upper surface opening of the inner box 6. The portion 7a is thinned and bent into a curved shape so as to be elastically deformed, so that almost no impact from the surroundings is transmitted to the cosmetic 1 in the inner box 6. In the figure, 8 is an adhesive layer for fixing the inner tray 2 to the bottom of the inner box 6, and 9 is a rod insertion for removing the inner tray 2 from the adhesive layer 8 and taking it out. It is a hole.

Japanese Patent No. 4601929

  The cosmetic container has excellent impact resistance. When the container body 3 is turned upside down, the space between the opening edge surrounded by the lower end edge of the outer peripheral wall 5 and the bottom of the inner box 6 is improved. In order to give a simple impression, it is used not only as a general compact container for customers to use on hand, but as a refill container for exchanging medium dishes and a tester container for store display. Yes.

  However, there is a strong demand not only for a refill container and a tester container but also for a general compact container, and it is strongly desired to provide excellent impact resistance. An inner box 6 as shown in FIG. Incorporation into

  For example, as shown in FIG. 7, prepare an intermediate tray housing case 10 having the same configuration as the container main body 3 in FIG. 6 (the same reference numerals are assigned to the same parts as the container in FIG. 6 and description thereof is omitted), It can be considered that this is accommodated in the recess 12 of the container body 11 of a general compact container. However, if this is done, excellent impact resistance can be obtained, but space is wasteful, and the compact container is enlarged, which is not preferable for carrying.

  Therefore, for example, as shown in FIG. 8, the container body 11 in FIG. 7 is constituted by two members, a frame-like body 13 and a bottom wall 14 that closes the lower end opening of the frame-like body 13. It is also conceivable to ultrasonically bond the upper end portion 14a of the peripheral wall rising from the peripheral edge portion and the lower end portion 5a of the outer peripheral wall 5 of the inner tray housing case 10. If it does in this way, the inside tray storage case 10 can be attached in the state which floated from the bottom wall 14 inside the container main body 11, and the whole can be designed comparatively compactly.

  However, in order to ultrasonically bond the outer peripheral wall 5 of the inner tray housing case 10 and the peripheral wall of the bottom wall 14, it is necessary to form a welding rib on one end face, so that both end faces must be made thick to some extent. In addition, coupled with the fact that this portion is entirely fitted inside the peripheral wall of the frame-like body 13, the degree of freedom of the inner tray housing case 10 is greatly limited, and the impact resistance is greatly increased. It will drop to. Further, in the inner tray housing case 10, the inner box 6 and the connecting wall portion 7 are thin, the outer peripheral wall 5 is thick, and the thickness of the partial portions is different. Is non-uniform, and there is a problem that defective products are easily formed. Furthermore, in the case where the frame 13 is formed of a resin different from the constituent resins of the inner tray housing case 10 and the bottom wall 14 in terms of appearance and the like, a part of the foreign resin is also present during ultrasonic bonding. Since it may melt and enter the adhesive interface to reduce the adhesive strength, it is not preferable.

  The present invention has been made in view of such circumstances, and an object of the present invention is to provide a cosmetic container that is excellent in impact resistance to an inner dish, is compact in its entirety, and has excellent moldability.

  In order to achieve the above object, the present invention includes a frame-shaped main body, an intermediate tray housing case that is fitted into the frame-shaped main body from above, and an intermediate tray housing case that is fitted into the frame-shaped main body from below. A bottom wall cover that serves as a bottom wall of the frame-shaped main body and a lid that covers the upper surface of the frame-shaped main body, and the frame-shaped main body has at least two opposing portions of the inner peripheral surface thereof. In the portion, there is an engaging portion that can be engaged with the above-described intermediate dish housing case, and the above-described intermediate dish housing case is horizontally disposed from a concave portion that can accommodate the inner tray filled with cosmetics and an upper end portion of the peripheral wall of the concave portion. A flange portion extending outward in the direction, and an engaged piece that is suspended from the flange portion and whose lower end portion can engage with the engagement portion of the inner peripheral surface of the frame-shaped main body, The wall cover is disposed in the frame opening of the frame-shaped main body and has a gap with respect to the bottom wall of the intermediate tray housing case It has a bottom wall portion that becomes a bottom wall of the frame-shaped main body and a peripheral wall portion that rises from the peripheral edge portion, and at least two opposed upper end portions of the peripheral wall portion of the bottom wall cover are accommodated in the inner tray. The first gist is a cosmetic container that is inserted between the peripheral wall of the concave portion of the case and the engaged piece, and presses and urges the engaged piece of the intermediate tray housing case toward the frame-shaped main body. .

  In addition, the present invention has, in particular, a cosmetic container in which the concave peripheral wall portion facing the engaged piece that hangs down from the flange portion is cut out in the above-described inner tray housing case, Among them, in particular, the thickness of the engaged piece of the inner tray housing case is set to 0.4 to 1.0 mm, and the thickness of the peripheral wall of the bottom wall cover is set to 0.4 to 1.0 mm. The cosmetic container is a third gist.

  That is, the cosmetic container of the present invention comprises a conventional part corresponding to the container main body, which is composed of two members, a frame-shaped main body and a bottom wall cover, and the middle tray housing case is inserted into the frame-shaped main body from above. In addition, a bottom wall cover is inserted from the bottom so that it can be assembled integrally. The intermediate tray housing case not only simply accommodates the intermediate tray, but also a flange portion extending outward from the upper end of the peripheral wall of the recess for accommodating the intermediate tray, and a suspended member hanging from the flange portion. And the lower end portion of the engaged piece is engaged with the engaging portion provided on the frame-shaped main body side. Can be held in a state where a gap is provided between the peripheral wall and the bottom wall cover of the frame-shaped main body, and the original shock resistance of the inner tray housing case is not impaired.

  In addition, the upper end portion of the bottom wall cover enters between the peripheral wall of the recess of the intermediate tray housing case and the engaged piece, and presses and urges the engaged piece of the intermediate tray storage case toward the frame-shaped main body. Therefore, the engagement between the middle tray housing case and the frame-shaped main body and the engagement between the middle tray housing case and the bottom wall cover become strong, and the middle tray housing case and the bottom to be bonded by ultrasonic bonding or the like. Even if the joint area with the wall cover is small, this portion does not come off. Therefore, both the thickness of the engaged piece of the intermediate tray accommodating case and the thickness of the peripheral wall of the bottom wall cover can be reduced, and the two members of the intermediate tray accommodating case and the bottom wall cover can be efficiently manufactured. It has the advantage of being able to.

  In addition, since the engaged piece and the bottom wall cover of the middle tray housing case are joined on the side that does not contact the frame-shaped main body, the frame-shaped main body accommodates the middle tray when this joining is performed by ultrasonic bonding. Even if it is formed of a resin different from that of the case and the bottom wall cover, it does not partially melt at the time of adhesion and does not ooze out to the joint, and troubles such as a decrease in adhesive strength can be avoided.

  Among the present invention, in particular, in the above-described intermediate dish housing case, a portion in which a concave peripheral wall portion facing a to-be-engaged piece hanging from the flange portion is cut out is in a state of being fitted into the frame-shaped main body. The inner tray storage case has a higher degree of freedom and is more shock resistant.

  Further, among the present invention, in particular, the thickness of the engaged piece of the intermediate tray housing case is set to 0.4 to 1.0 mm, and the thickness of the peripheral wall of the bottom wall cover is 0.4 to 1.0 mm. In the same manner, the above-described inner tray housing case has a higher degree of freedom and is more excellent in impact resistance. In addition, the space required for the engagement between the inner tray housing case and the bottom wall cover can be reduced, and the overall configuration has the advantage of a more compact shape.

It is explanatory drawing for demonstrating the subject of this invention.

  Next, embodiments of the present invention will be described in detail with reference to the drawings. However, the present invention is not limited to the following embodiments.

  FIG. 1 shows an embodiment of a cosmetic container according to the present invention. However, an exploded perspective view is shown in order to clearly show what is actually assembled integrally. Further, FIG. 2A shows a plan view thereof (the cover body 23 is partially shown by a chain line), and FIG. 2B shows a longitudinal sectional view of the cover body 23 in a closed state. Yes.

  That is, the cosmetic container is inserted into the frame-shaped main body 20, the middle dish containing case 21 inserted into the frame-shaped main body 20 from above, and the frame-shaped main body 20 from below. A bottom wall cover 22 serving as a bottom wall and a lid body 23 that covers the upper surface of the frame-shaped main body 20 are provided.

  Then, in the recess 30 of the intermediate tray housing case 21, a square-shaped intermediate tray 24 provided with a partition so as to be filled with four types of cosmetics is accommodated.

  The frame-like main body 20 has a rectangular shape that is long in a plan view (long in the left and right in the drawing in FIG. 2), and is provided with a recess 25 on the front side that can accommodate cosmetic accessories. An opening 26 (see FIG. 1) having a square shape in plan view is formed on the rear side, and an inner peripheral surface of a peripheral wall surrounding the opening 26 (the front wall also serves as the rear wall of the recess 25). Among them, on the plane portion excluding the four corners, the protruding ridges 27 and the ridges 28 extending in the horizontal direction are formed side by side (see FIG. 2B and FIG. 4 which is a partially enlarged view thereof). .

  In addition, the front end surface of the frame-shaped main body 20 (returning to FIG. 1) except for the left and right end edges and the lower end edge is formed into a concave paragraph, and the front end of the lid 23 is formed at the center upper end. A protrusion 29 for closing the lid 23 by engaging with a hook 50 provided at the center of the part is provided.

  The rear end portion of the frame-shaped main body 20 is notched at the central portion, and a hinge block 51 hanging from the rear end portion of the lid body 23 is inserted into this portion, and hinge pins 52 are inserted from both left and right ends. The frame-shaped main body 20 and the lid body 23 are hinge-connected.

  On the other hand, as shown in FIG. 3, the middle tray housing case 21 fitted into the frame-shaped main body 20 is configured to house the middle tray 24 with a bottom wall 31 and a peripheral wall 32 rising from the peripheral edge thereof. A recess 30 is formed. And the flange part 33 is extended in the horizontal direction outward from the upper end part of the said surrounding wall 32, and the to-be-engaged piece 34 extended by predetermined length along each edge | side at the center part of each of the four sides of the front, back, left, and right Is drooping. A ridge 35 extending in the horizontal direction is formed on the outer side of the lower end of each engaged piece 34, and this ridge 35 is provided with a ridge 27 provided on the inner peripheral surface of the peripheral wall of the frame-shaped main body 20. It gets over and engages with the recess 28 below (see FIG. 4).

  And the part which opposes the to-be-engaged piece 34 which hangs outward among the four surfaces of the front and rear, right and left of the peripheral wall 32 of the said inner tray accommodating case 21 is notched larger than the to-be-engaged piece 34 (FIG. Return to 3). By providing the notch 36, the degree of freedom of the engaged piece 34, and hence the degree of freedom of the recess 30 surrounded by the peripheral wall 32, is increased, and it is easier to absorb the impact received from the outside. It becomes a structure. The size of the notch 36 is set such that the length in the longitudinal direction is 0.5 to 2 mm longer than the length of the engaged piece 34, and the notch width (indicated by W in FIG. 4). Setting to 3 to 10 mm is preferable because it is excellent in the balance between the impact resistance improvement effect and the strength of the inner tray housing case 21.

  Further, the bottom wall cover 22 fitted into the frame-shaped main body 20 from the bottom closes the lower portion of the opening 26 (see FIG. 1) of the frame-shaped main body 20 to form a bottom wall portion 40 that serves as a bottom wall, and its peripheral portion. And a peripheral wall portion 41 that rises from. Of the upper end portion of the peripheral wall portion 41, the narrow portion on the inside rises upward over the entire circumference, whereby the ridge portion 42 is formed. Moreover, the part which went down one step | step outside the protruding item | line part 42 is the taper part 43 of the downward inclination toward the outer side.

  Then, when the bottom wall cover 22 is inserted into the frame-shaped main body 20 from below, the protrusions 42 and the taper portions 43 of the peripheral wall 41 are engaged with the inner tray housing case 21 inserted from above the frame-shaped main body 20. It is inserted between the joining piece 34 and the peripheral wall 32 to press and urge the engaged piece 34 outward and the peripheral wall 32 further inward. The ridges 27 and the ridges 28 of the main body 20 are more firmly engaged.

  The upper end portion of the bottom wall cover 22 is integrally joined to the inner corner portion (portion P indicated by a fine slanted line in FIG. 4) of the engaged piece 34 of the inner tray housing case 21 by ultrasonic bonding. It has become. By the joining, the corner portion P of the engaged piece 34 and the taper portion 43 on the bottom wall cover 22 side are melted and integrated, and both are firmly fixed, and neither is detached from the frame-shaped main body 20. In this state, the bottom wall portion 40 of the bottom wall cover 22 is disposed with a gap between the bottom wall portion 22 and the bottom wall 31 of the inner tray housing case 21.

  According to the cosmetic container having the above-described configuration, the middle tray housing case 21 is inserted from above and the bottom wall cover 22 is inserted from below into the frame-shaped main body 20 instead of the conventional container main body. It is assembled to. And the flange part 33 and the to-be-engaged piece 34 which hangs down from this flange part 33 are provided in the recessed part 30 for accommodating the inside dish of the said inside dish accommodating case 21, The lower end part of this to-be-engaged piece 34 is The ridge 27 and the ridge 28 provided on the inner peripheral surface of the frame-shaped main body 20 are engaged. Therefore, the concave portion 30 of the intermediate tray accommodating case 21 can be held with a gap between the peripheral wall of the frame-shaped main body 20 and the bottom wall cover 22, and the intermediate tray accommodated in the concave portion 30. 24, little impact from outside is transmitted. In particular, the portion of the engaged piece 34 other than the engagement with the ridges 27 and the recesses 28 of the frame-shaped main body 20 is not limited to the frame-shaped main body 20 or the inner tray housing case 21. Since there is a gap, the impact absorbing power in this portion is very high, and particularly excellent impact resistance is exhibited.

  Moreover, the upper end portion of the bottom wall cover 22 enters between the peripheral wall 32 of the inner tray housing case 21 and the engaged piece 34, and presses and urges the engaged piece 34 toward the frame-shaped main body 20. Therefore, the engagement between the middle tray housing case 21 and the frame-shaped main body 20 and the engagement between the middle tray housing case 21 and the bottom wall cover 22 are both strengthened. Even if the joining area with the wall cover 22 is small, the joining portion does not come off. Therefore, both the thickness of the engaged piece 34 of the intermediate tray housing case 21 and the thickness of the peripheral wall portion 41 of the bottom wall cover 22 can be reduced (for example, about 0.4 to 1.0 mm). There is an advantage that the two members of the housing case 21 and the bottom wall cover 22 can be efficiently manufactured. Incidentally, in the above example, the thickness (indicated by D1 in FIG. 4) of the engaged piece 34 of the inner tray housing case 21 and the thickness (indicated by D2 in FIG. 4) of the peripheral wall portion 41 of the bottom wall cover 22 are: Both are 0.8 mm.

  Further, since the engaged piece 34 and the bottom wall cover 22 of the inner tray housing case 21 are joined on the side not in contact with the frame-like main body 20, when this joining is joined by ultrasonic bonding, the frame-like main body Even if 20 is formed of a resin different from the inner tray housing case 21 and the bottom wall cover 22, it does not partially melt at the time of bonding and does not ooze out to the joint portion, thereby avoiding problems such as a decrease in adhesive strength. can do.

  In addition, since the notch 36 is provided in the peripheral wall of the intermediate tray accommodating case 21 at a portion facing the engaged piece 34 that hangs down from the flange portion 33, the intermediate tray accommodated in the frame-shaped main body 20 is accommodated. The case 21 has a higher degree of freedom, and has better impact resistance.

  However, the cutout portion 36 of the inner tray housing case 21 is not necessarily required. For example, as shown in FIG. 5, a part of the flange portion 33 that extends horizontally (a part of each of the four sides on the front, rear, left, and right sides). Can be folded downward to form the engaged piece 34, and a ridge 35 can be provided at the lower end thereof. Also in that case, it is necessary that the upper portion of the peripheral wall portion 41 of the bottom wall cover 22 enters between the engaged piece 34 and the peripheral wall 32. And it is preferable to provide an ultrasonic bonding rib on the upper outer surface of the peripheral wall portion 41.

  Of course, the joining of the engaged piece 34 of the intermediate tray housing case 21 and the peripheral wall portion 41 of the bottom wall cover 22 may be performed by bonding using an adhesive instead of ultrasonic bonding.

  Further, in the above example, the recess 25 for housing the cosmetic accessory is provided on the front side of the frame-shaped main body 20, but this is not necessarily required, and the frame-shaped main body 20 only includes the frame-shaped body surrounding the opening 26. It may be composed of.

  Furthermore, in the above example, in the inner tray housing case 21, the engaged pieces 34 are provided on the four sides of the front, rear, left and right, respectively, but the engaged pieces 34 are provided at two opposing positions on the front and rear or the left and right. You can do that. However, it is preferable to provide the engaged pieces 34 evenly in the circumferential direction because shock can be absorbed in a balanced manner.

  In the above example, the engagement between the frame-shaped main body 20 and the lid body 23 is performed by the projection 29 and the hook 50 provided at the front end portions of the both, but the engaging means is not limited to this. It may be of a type that attaches and detaches at the left and right side portions, or that that opens and closes by sliding the lid 23 back and forth.

  INDUSTRIAL APPLICABILITY The present invention can be used for a cosmetic container in which a middle dish is accommodated through a middle dish housing case excellent in impact resistance.
