JPS5843527Y2 - Small container without cap - Google Patents

Description

[Detailed explanation of the idea] This proposal concerns a small container made of synthetic resin without a cap.

For example, a small container filled with a sample product is often disposable and can be used only once, and is free of charge, so it is desirable that the cost of the small container be low.

However, if the sample storage item is relatively expensive,
Preferably, the small container also has an appearance that corresponds to the contents stored therein.

Based on such a request, the present applicant previously filed a Utility Application in 1983-18.
No. 2047 (Japanese Utility Model Publication No. 55-96021) was filed, and the present invention is a further improvement of the invention of the previous application.

Referring to the drawings below, the small container according to the present invention consists of a small container body 1 with an open top end, and a closing means provided on the open surface of the top end.

The small container body 1 is molded from a synthetic resin material that whitens due to crystallization, for example, a saturated polyester resin.

The upper part of the mouth and neck is a large outer diameter part 2 which has the appearance of a cap without a top wall fitted onto the outer surface of the mouth and neck of a small container, and only the middle part in the vertical direction of the large outer diameter part is formed by crystallization. A whitened part 3 is formed, and all parts of the small container body other than the whitened part are formed transparent.

By vertically disposing knurling on the cap circumferential wall-like external portion, the appearance of the cap circumferential wall can be further improved.

The inner peripheral part 4 of the upper end surface may be formed slightly higher than the outer peripheral part 5.

This will be discussed later. 6 is the lower part of the mouth and neck, and 7 is the torso.

The opening 8 at the upper end of the small container body is removably closed by suitable means.

The closing means may be a stopper 11 having a leg tube 10 suspended from the back surface of the top plate portion 9, as shown in the figure.

The stopper has a ring portion 12 around its top plate as shown in FIG.
A part of the ring is opened as a connecting part 13, and several parts are connected with broken pieces 14. When the ring part on the side facing the connecting part is pulled up, the broken pieces are broken. The ring part 12 stands up, and the entire stopper can be removed via the connecting part 13 by pulling the ring part upward using the ring part as a handle.

A sealing plate may be bonded as another closure means.

As mentioned above, if the inner peripheral part 4 of the upper end surface is made slightly higher than the outer peripheral part 5 and the lower surface of the closing means is brought into contact only with the inner peripheral part, the lower surface of the outer peripheral part of the closing means A gap 15 for hooking is formed between the large outer diameter portion 2 and the outer peripheral upper surface of the large outer diameter portion 2, which is convenient for removing the closing means.

As shown in FIG. 3, the small container body 1 having the above-described structure includes a transparent intermediate material 16 made of, for example, saturated polyester resin, which is cylindrical in shape and has an upper end opening and a bottom, and has a large outer diameter portion 2. Then, it may be placed in a blow molding mold at a temperature suitable for blow molding and blow molded.

Whitening of the peripheral wall-like appearance of the cap by crystallization may be performed either before or after the blow molding.

Note that whitening due to crystallization can be achieved by simply heating the relevant portion to the crystallization temperature and then cooling it back and forth.

The present invention has the above-mentioned structure, and is provided with a large outer diameter portion 2 that looks like a cap peripheral wall, and its upper end opening is closed. Therefore, although it has the appearance of a small container with a cap, it is actually a cap. In addition, the small container body is transparent in all parts except for the cap peripheral wall-like external part, and the large outer diameter part 2 has a two-tone color consisting of a white part and a transparent part. Therefore, the container can be made to have an extremely superior appearance.

Furthermore, when a stored item is placed inside the body of the small container, the body appears in the color of the stored item, making the small container look even more beautiful.
