Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a glass container for injecting and sealing a volatile or aromatic liquid substance such as a reagent or cosmetics such as perfume or emulsion.

[0002]

[Prior art]

 Conventionally, for example, a volatile or aromatic cosmetic liquid is poured into a glass container body, and a synthetic resin cap is tightly screwed into a screw portion of the container body.

[0003]

[Problems to be solved by the device]

 However, viscous substances such as milky lotion and surfactant gradually adhere to the threaded portion of the container body each time the cap is opened and closed, so the container body is made of glass and the surface is The cap may loosen easily because it is slippery. This also applies to aromatic substances such as perfumes. If the cap is loosened even slightly, volatiles evaporate and aromatics give off a scent. In extreme cases, the contents may spill out, especially when something like a perfume that you put in your handbag spills out of the handbag, the scent permeates the entire handbag, and once it does, it becomes a stain. Removal of this stain becomes extremely difficult. The cause of the looseness of the cap may be the problem of the characteristics of the contents as described above or the cap may be plastically deformed with time.

Therefore, an object of the present invention is to provide a glass container that prevents the cap from loosening.

[0005]

[Means for Solving the Problems]

 The feature of the present invention resides in that in the screw portion formed on the outer peripheral surface of the opening of the glass container main body, the protrusion of the screw portion of the screw portion is formed to project laterally.

[0006]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings.

In FIG. 1, the glass container according to the present invention comprises a glass container body 1 and a deformable cap 2 screwed onto the container body, and the cap is made of polypropylene having a slight elasticity. It is made of resin. A male threaded portion 11 is formed on the outer peripheral surface of the opening of the container body 1, and a thread 12 of this threaded portion is formed with a radially enlarged protrusion 13 that projects laterally. The width of the protrusion 13 is sufficient to press the screw groove 21 (female screw portion) of the cap 2 and the height of the protrusion also presses the top of the protrusion to the bottom of the screw groove of the cap. Is enough for Further, the number of the projections 13 is provided in a symmetrical positional relationship, or three projections are provided so that the screwed state can be maintained in good balance when the cap 2 is screwed into the container body 1. The parts may be provided at positions displaced in the same angle.

The container body 1 is preferably made of hard glass excellent in chemical resistance, and therefore, a tube of hard glass is cut by a burner more than a conventional blow molding method. It is possible to make seamless ones. In this case, the screw part of the container body is manufactured by rotating the glass tube in one direction in a heated state as shown in FIG. A hole 32 for forming the protrusion 13 is formed in the forming groove 31 of 12 to rotate the glass tube and the mold 3 in synchronization.

Then, when the cap 2 is screwed into the container body 1, the projection 13 of the thread 12 of the container body slightly deforms the thread groove 21 of the cap, and the portion becomes uneven, It is possible to prevent the cap from loosening.

The shape of the protrusion is appropriately selected from a hemispherical shape and a triangular shape.

FIG. 3 shows another embodiment in which the projection 22 is formed on the thread 22 of the cap 2. The other structure is substantially the same as that of FIG.

In FIG. 4, the screw thread is omitted in the threaded portion 11a of the container body 1a, and a plurality of protrusions 13a are spirally provided at predetermined positions at a position where the screw thread is originally formed. It is a thing. The cap 1 is the same as that of FIG.

FIG. 5 shows that the screw portion 11b of the container body 1b has the threads 12b and 12c formed by bending at a right angle, and the projection 13b is provided so as to protrude from the horizontal thread 12b. . This cap is formed with a groove into which the horizontal thread 12b can enter. This is convenient for a container such as a reagent container which is frequently opened and closed because it can be fitted into the container body 1b by simply rotating the cap by approximately 90 degrees.

[0014]

[Effect of device]

 According to the present invention, the cap is securely screwed to the container body and the loosening of the screw can be completely prevented, which is convenient as a container for a volatile fragrance or the like.
