Description

Container for stick-shaped cosmetics

Technical Field

The present utility model relates to a stick-type cosmetic. In particular, it relates to a container for containing stick-shaped cosmetics.

Background

The conventional principle of rotating and lifting the center of the stick-shaped cosmetic container in which the mechanisms such as the guide vertical groove, the guide vertical rib, and the screw thread are disposed at the periphery of the content as shown in fig. 1 and 2, and the conventional principle of rotating and lifting the center of the stick-shaped cosmetic container in which the mechanisms such as the guide vertical groove, the guide vertical rib, and the screw thread are disposed below the content as shown in fig. 3 and 4, are realized by the combination of the inner cylinder member a, the middle dish member b, the screw member c, and the guide vertical groove a1, the guide vertical rib b1, and the screw thread c1 attached thereto, which constitute the center. Then the combined middle beam core is integrally fixed on the container body to form a complete rod-shaped cosmetic container.

However, the rod-shaped cosmetic container and the middle bundle core of the rod-shaped cosmetic container having such a structure have the following problems:

1. the guide vertical groove a1, the guide vertical rib b1, the screw c1 and other mechanisms in the middle beam core are positioned at the periphery of the content (stick-shaped cosmetic paste) arranged on the middle dish part b, so that the outer diameter of the middle beam core is increased, the section difference between the diameter of the middle beam core and the diameter of the content e is increased, and the appearance is deteriorated. And the contact portion with the content cannot be made smooth due to the thread c1 or the guide vertical groove a1, so that the content cannot be made scratch-resistant and soft in texture.

2. The guide vertical groove a1, the guide vertical rib b1, the screw thread c1 and other mechanisms in the middle beam core are positioned below the content, and the screw part c is arranged at the periphery of the inner cylinder part a, so that the outer diameter of the lower part of the middle beam core is large and bloated, and the middle beam core is inconvenient to directly insert into a general cosmetic container body. And the screw part c is not easy to be demoulded, so that the screw pitch is very small, and the micro-motion container is inconvenient to manufacture.

3. The middle beam core is not easy to decompose after being fixed with the cosmetic container body, and the cosmetic container body and the middle beam core are abandoned together after the cosmetic content is used up, so that waste is caused.

4. The existing stick-shaped cosmetic container has poor sealing property, so that active ingredients of the cosmetic content are easy to volatilize, the efficacy of the cosmetic content is reduced, and the cosmetic content is wasted.

Disclosure of Invention

The utility model aims to solve the technical problem of providing a rod-shaped cosmetic container which has a simple structure, is convenient to decompose, and is not easy to scratch and volatilize when being loaded with the rod-shaped cosmetic paste.

The technical scheme adopted by the utility model is as follows: the utility model provides a stick-shaped cosmetic container, is in including cosmetic container body and lid the upper cover on cosmetic container body upper portion, this internal bundle core in the stick-shaped cosmetic that is provided with the loading of cosmetic cream of cosmetic container, cosmetic container body lower part inner peripheral face on be formed with the round can with the fixed a plurality of perpendicular muscle of a plurality of numbers of mutual embedding of fixing that the bundle core lower part corresponds the position department in the stick-shaped cosmetic, anti-rotation perpendicular muscle upper end be formed with the round outwards protruding and be used for embedding the anti-decomposition horizontal muscle that forms in the fixed recess that forms in bundle core lower part corresponds the position department in the stick-shaped cosmetic, cosmetic container body upper portion be formed with the outer convex structure of round in the near port department, the inner side cover have flexible inner cover the flexible inner cover inboard correspond the outer convex structure of cosmetic container body upper portion be formed with the round can with outer convex structure forms complex gas tightness arch.

According to the container for rod-shaped cosmetics, the middle dish part and the spiral part are positioned below the content and are contained in the outer cylinder part, and the effects of fixation and disassembly are achieved through the mutual matching of the anti-decomposition transverse ribs on the cosmetic container body and the fixing vertical ribs on the spiral part. The inner surface of the middle beam core is smooth, and can accommodate soft contents. The upper and lower outer diameters of the middle beam core are consistent, so that the design of the container shell is facilitated. The mould structure is easy to realize, the screw pitch of the screw component is smaller, the micro-motion performance of the container is convenient to improve, and the micro-motion type rod-shaped cosmetic container can be manufactured. And through increasing the inner cup, improved the gas tightness of cosmetic container, make cosmetic content active ingredient be difficult to volatilize.
