Description

[Detailed explanation of the idea] "Industrial application field" This proposal concerns containers with push-pull caps.

``Prior Art'' Conventionally, this type of container has a main body with a locking protrusion around the outer periphery of the mouth, a tapered shoulder extending below the mouth, and a container body with a tapered shoulder extending from the inside of the top wall. a cap having an appropriate number of vertically disposed elastic locking pieces that engage with the locking protrusion, the peripheral wall being configured to be elastically deformable in bending, and bringing the lower end of the peripheral wall into contact with the upper surface of the shoulder; (Utility Model Application Publication No. 58-130947).

In the case of this container, when the cap is placed over the mouth of the container body and pushed down, the elastic locking piece engages with the locking protrusion, allowing the cap to be easily installed. When the cap is pressed toward the cap and elastically deformed, the lower end of the section slides up the upper surface of the tapered shoulder, pushing the cap upward, the elastic locking piece disengages from the locking protrusion, and the cap floats up. , can be easily removed.

``Problem to be solved by the invention'' By the way, in this case, when removing the cap, if the lower part of the peripheral wall is pressed horizontally from both the left and right sides at the same time, the engagement can be done efficiently and easily.
Can be made to leave.

However, if the pressing location or the pressing direction is misaligned, it will not be easy to separate, and in order to compensate for this inconvenience, the engagement will have to be made looser, which may lead to unexpected separation.

The present invention attempts to solve these conventional problems.

"Means for Solving the Problems" As shown in the illustrated embodiment, the present invention provides a locking protrusion 16 around the outer periphery of the opening 15 of the container body 1,
An umbrella-shaped cap guide 2 is attached to the neck 13 of the container body 1.
is fixed, the cap guide has a tapered flange 23 protruding from a base 21 fixed to the neck 13,
A pair of left and right elastic pressing pieces 24, 24 are erected from the edge of the tapered flange, and a cap 3 is provided to cover and close the opening 15. Locking protrusion 16
An appropriate number of elastic locking pieces 33 are provided vertically to engage with the elastic locking pieces 33, and the peripheral wall 32 is configured to be elastically deformable by bending and inserted into the inner side of the elastic pressing pieces 24. It is configured so as to be brought into contact with the edge of 23.

Bulging portions 25, 25 are provided on the inner surfaces of the elastic pressing pieces 24, 24.

``Operation'' With the above structure, when the cap 3 is placed over the opening 15 of the container body 1 from above and pushed down, the elastic locking pieces 33 engage with the locking protrusions 16 of the opening 15 and are engaged. The central part of the top wall 31 is held at the mouth part 15.
The lower end of the peripheral wall 32 abuts against the edge of the tapered flange 23 of the cap guide 2 and maintains this state.

Next, the elastic pressing pieces 24, 2 of the cap guide 2
When 4 is strongly pressed inward, the bulge 25,
At 25, the peripheral wall 32 of the cap 3 is pushed in and elastically deformed, and as a result, the lower end of the peripheral wall 32 slides up on the tapered flange 23 of the cap guide.
The cap 3 is pushed upward, and the elastic locking pieces 33 of the cap 3 are disengaged from the locking projections 16 of the mouth portion 15 and float. After that, all you have to do is pull up the cap 3.

"Example" The illustrated embodiment will be described below.

In the figure, 1 is a container main body, 2 is a cap guide attached to the shoulder of the container main body, and 3 is a cap that fits into the mouth of the container main body and is in contact with the cap guide. , which is suitably made of synthetic resin.

The container body 1 has a body 11 that can be squeezed,
A shoulder portion 12 extending above the torso is formed into a tapered shape,
A concave groove 14 is provided around the outer periphery of the neck 13 that extends above the shoulder, a mouth 15 that extends above the neck is formed with a slightly smaller diameter, and a locking protrusion 16 is provided on the outer periphery of the mouth.
is established.

The cap guide 2 is formed in an umbrella shape, and is provided with a fitting base 21 that fits on the outer periphery of the shoulder portion 12.
An engaging protrusion 22 that engages with the groove 14 is provided around the upper edge of the fitting base, and a tapered flange 23 that overlaps with the shoulder 12 is provided on the lower edge of the fitting base, A pair of left and right elastic engagement pieces 24, 24 are integrally erected at the edges of the tapered flange, and the elastic pressing pieces bend the upper part outward and form inward bulges 25, 25 in the middle of the inner surface. It protrudes and is fitted and fixed to the neck 13 to shoulder 12.

The cap 3 fits inside the elastic pressing pieces 24, 24 from the peripheral edge of the top wall 31 where the center of the inner surface abuts the top surface of the mouth portion 15, and the lower end thereof fits into the edge of the tapered flange 23. A tapered peripheral wall 32 with a small inclination and elastically deformable is provided vertically in contact with the top wall 31, and a plurality of elastic locking pieces 33 which engage with the locking protrusions 16 of the mouth portion 15 are arranged in an annular shape from the inner surface of the top wall 31. An engaging protrusion 34 is provided around the base of the elastic locking piece to fit with the outer edge of the opening 15.

``Effects of the invention'' According to the present invention, by placing the cap 3 over the opening 15 of the container body 1 and pushing it down, it can be attached with one hand or with a single push. The cap 3 can be detached, and at that time, the peripheral wall of the cap is not pressed directly but through the elastic pressing pieces 24, 24, so that the optimum position can always be reliably pressed, and the press can be carried out easily. It can be removed efficiently and easily, and this also means that
Strong engagement between the elastic locking pieces 33 and the locking protrusions 16 is enabled, the cap 3 can be firmly and reliably held, and accidental detachment can be completely eliminated. Also, when installing cap 3,
The elastic pressing piece 24 of the cap guide 2
By inserting the cap 3 into the inside of the cap, the cap 3 can be automatically aligned, and the cap 3 can be attached and detached extremely easily, which is very convenient for use.

It is simple in structure and manufacture and can be provided at low cost, and is extremely useful in practice.
