Description

[Detailed description of the invention] Industrial application field This invention relates to a rod-shaped cosmetic container with emphasis on airtight structure.

Problems to be Solved by Conventional Technologies and Ideas In conventional bar-shaped cosmetic containers, a packing or inner tube made of rubber or resin is installed inside the cap, and these members have an opening on the side of the container body or an inner cylinder. There are some products that incorporate an airtight structure in which the two sides are brought into close contact with each other, but it is extremely difficult to ensure sufficient airtightness with these structures.The present invention is a rod-shaped cosmetic that solves the above drawbacks with a simple structure. The purpose is to provide food containers.

Measures to solve the problem The present invention provides an annular uneven part at the fitting part of the lower part of the resin cap body installed inside the cap and the inner tube,
The feature is that the uneven parts are engaged with each other and a slight elasticity is imparted to the lower part of the cap body, and this elasticity makes the engagement or contact of the uneven parts even tighter. Hakama tube 1 with spiral groove 2
A vertical hole 4 is bored in both side walls of the lower half part, and an annular convex part 5 bored in the outer circumferential surface of the middle part is engaged with an annular concave part 6 of the upper opening made in the inner circumferential surface of the hakama tube 1. A body tube 3 that is inserted into the hakama tube 1 as if to hold the hakama, and a cosmetic dish 7 that is housed in the body tube 3 and has an annular collar 8 that projects from the outer circumferential surface of the body tube 3 and that is in close contact with the inner circumferential surface of the body tube 3. , a leg tube 9 that hangs down from the bottom of the cosmetic dish 7 and has a pin 10 protruding outward from the bottom that passes through the vertical hole 4 and engages with the spiral groove 2; the hakama tube 1 and the body tube 3; A middle fitting cylinder 11 is interposed with its upper part protruding above the hakama cylinder 1 and is fixed to the hakama cylinder 1 side to prevent the annular convex part 5 of the body cylinder 3 from being pulled out. Fitting part 1 of cylinder 11
A cylindrical cap 12, which is removably fitted into the cap 1', has an inner diameter widened part 12' on the inner peripheral surface of the lower part, and a resin cap body 13 installed inside the cap 12 has a slightly elastic shape with the lower part expanded outward. This bulging part 13' is located in the inner diameter widened part 12' of the cap 12, and the annular groove 14 bored in the inner circumferential surface of the bulging part 13' has a bulging part 13'. engaging an annular rib 15 with a mountain-shaped cross section protruding from the outer peripheral surface of the fitting portion 11' of the inner fitting cylinder 11, and bringing the opening edge of the annular groove 14 into close contact with the base end of the annular rib 15; Further, a dish-shaped engagement piece 16 having elasticity and having a cross section of 1 is provided protruding from the top of the cap body 13 and attached to the cap 1.
An engagement recess 17 having a cross-section [shaped] is bored in the inner surface of the top wall of 2.
The gist is a structure that engages with the

Embodiments The details of the present invention will be described below with reference to embodiments shown in the drawings. 1 is a hakama tube having a spiral groove 2 on the inner peripheral surface;
3 has a vertical hole 4 bored in both side walls of the lower half, and an annular convex part 5 protruding from the outer circumferential surface of the middle part engages with an annular concave part 6 formed on the inner circumferential surface of the hakama tube 1 and opened on the upper surface. A body tube 7 is inserted into the hakama tube 1 so as to hold the body tube 1, and a cosmetic plate 9 is housed in the body tube 3, and an annular flange 8 protruding from the outer periphery of the opening is brought into close contact with the inner circumferential surface of the body tube 3. It is a leg tube that is integrally formed at the lower part of the cosmetic dish 7 and hangs down, and a pin 10 protruding from the lower part passes through the vertical hole 4 and engages with the spiral groove 2, thereby preventing the rotation of the hakama tube 1. As a result, the cosmetic dish 7 moves up and down inside the body barrel 3. Reference numeral 11 denotes a middle fitting tube fixed to the hakama tube 1 side between the hakama tube 1 and the body tube 3 so that its upper half protrudes above the hakama tube 1, and its lower end is attached to the annular shape of the body tube 3. It is located directly above the protrusion 5 and functions to prevent the annular protrusion 5 from being pulled out. Reference numeral 12 denotes a cylindrical cap that is removably fitted into the fitting portion 11' of the inner tube 11, and has an inner diameter enlarged portion 12' on the lower inner circumferential surface. Reference numeral 13 denotes a resin cap body installed inside the cap 12, and a bulge 13' that expands outward and has some elasticity is provided at the lower part. 12', and the fitting part 1 of the inner sleeve 11 is inserted into the annular groove 14 bored in the inner peripheral surface of the bulged part 13'.
An annular rib 1 with a mountain-shaped cross section protruding from the outer peripheral surface of 1'
5, the opening end surface of the annular groove 14 is brought into close contact with the base end of the annular rib 15, and the cap body 1 is brought into close contact with the base end of the annular rib 15.
A dish-shaped engagement piece 16 having an elastic shape and having a shape of 3 is engaged with an engagement recess 17 having a shape of a cross section formed on the inner surface of the top wall of the cap 12.

Functions and Effects of the Invention Accordingly, in the present invention, an annular flange 8 is protruded from the outer peripheral surface of the cosmetic dish 7, and this annular flange 8 is brought into close contact with the inner periphery of the body tube 3, so that the body tube can be opened from the bottom of the container. When the cap 13 is attached, the annular rib 15 of the inner tube 11 is inserted into the annular groove 14 of the bulge 13' in the cap body 13. The opening edge of the annular groove 14 is brought into close contact with the proximal end of the annular rib 15 having a mountain-shaped cross section, and the elasticity of the bulged portion 13' further increases the density of the close contact. , completely blocks the intrusion of outside air, and together with the internal airtightness of the annular flange 8 of the cosmetic dish 7, an extremely high airtightness is obtained. Not only can a stable fitted state of the cap 12 be obtained by the engagement of is adapted to engage with an engagement recess 17 in the shape of a cross section formed on the inner surface of the top wall of the cap 12, and has the advantage that the cap body 13 can be easily and stably attached to the cap 12. be.
